Update on Receptor-Like Kinases and the Cell WallThe Role of Receptor-Like Kinases in Regulating Cell Wall Function1Blaire J.Steinwand and Joseph J.Kieber*Department of Biology,University of North Carolina,Chapel Hill,North Carolina27599–3280The plant cell wall is a rigid but highly dynamic structure that provides mechanical support,protection against pathogen attack,and determines the direction and extent of cell expansion(Humphrey et al.,2007). The dynamic nature of the plant cell wall allows growing cells to expand while providing the mechan-ical strength required to resist the forces of turgor pressure exerted on the cell(Cosgrove,2000).The properties of the cell wall are modified during growth and development as well as in response to a wide variety of environmental stimuli.In order to maintain the integrity of the wall and to adjust its properties to accommodate the changing needs of the cell,plants respond to perturbations to the wall and environmen-tal cues by remodeling matrix polysaccharides and by regulating the cell wall biosynthetic machinery. The components and mechanisms underlying such a signaling system remain largely unknown,but emerg-ing evidence has implicated several receptor-like ki-nases as regulators of cell wall function.Plant cell walls are composite structures composed primarily of cellulose and matrix polysaccharides such as hemicelluloses and pectins(Somerville et al.,2004). In addition to wall polymers,structural proteins pro-vide a quantitatively small but important contribution to the wall.The major load-bearing components of the cell wall are the cellulose microfibrils,which,in lon-gitudinally expanding cells,are deposited primarily in an orientation perpendicular to the axis of expansion, thus constricting radial expansion(Green,1980;Taiz, 1984;Baskin,2005).Consistent with a role in differen-tial cell expansion,cellulose-deficient mutants and seedlings treated with inhibitors of cellulose synthesis display reduced or no growth anisotropy,and this is generally accompanied by cell and organ swelling (Somerville,2006).The oriented deposition of cellulose is guided by underlying cortical microtubules;thus, cortical microtubules are thought to be key determi-nants of anisotropic growth(Baskin,2001;Paredez et al.,2006;Lucas and Shaw,2008).In the primary cell wall,cellulose is synthesized at the plasma membrane by a hexameric protein com-plex called cellulose synthase(CESA).Each hexamer is composed of six CESA proteins that each synthe-size a b-1,4-linked glucan chain.A combination of expression analyses,genetic studies,and coimmuno-precipitation experiments have defined roles for the various CESA isoforms in Arabidopsis(Arabidopsis thaliana).CESA1,CESA3,and CESA6interact with each other to form a class of rosettes that function in primary cell wall biosynthesis(Desprez et al.,2007). CESA2,CESA5,and CESA9also likely function in primary cell wall synthesis in a manner such that they are partially redundant with CESA6at different stages of growth(Desprez et al.,2007;Persson et al., 2007).CESA4,CESA7,and CESA8constitute a dis-tinct subset of rosettes that function in secondary cell wall biosynthesis(Taylor et al.,2000,2003).Single mutants in any one of the genes encoding these CESA proteins are deficient in cellulose biosynthesis,which suggests that a functional cellulose synthase complex requires contributions from three different CESA subunits(Desnos et al.,1996;Arioli et al.,1998;Taylor et al.,1999,2000;Fagard et al.,2000;Can˜o-Delgado et al.,2003;Taylor,2008).The same structure and composition that lends strength and rigidity to the wall also serves to constrain cell expansion.While cell wall loosening is essential for expansion,this must be balanced with polymer syn-thesis and wall restrengthening to prevent the cell wall from rupturing.Such wall remodeling is facilitated by the activity of loosening and strengthening agents that modify cell wall polysaccharides.For example,wall loosening is accomplished through the activities of hy-droxyl radicals,expansins,xyloglucan endoglucosylase/ hydrolases,and endo-(1,4)-b-D-glucanases,whereas the extensins and peroxidases function in wall rigid-ification(Cosgrove,2005;Humphrey et al.,2007). Coordinating wall loosening with wall-strengthening activities during cell expansion requires the ability of the cell to monitor changes in wall integrity and to signal back to regulate the machinery involved in the synthesis and modification of the cell wall compo-nents.Such a cell wall signaling system has been well characterized in the yeast Saccharomyces cerevisiae (Levin,2005).In this system,the cell Wall integrity and Stress response Component(WSC)and Mating Induced Death2(MID2)cell surface receptors func-1This work was supported by the National Science Foundation (grant no.IOS–0624377).*Corresponding author;e-mail jkieber@.The author responsible for distribution of materials integral to the findings presented in this article in accordance with the policy described in the Instructions for Authors()is: Joseph J.Kieber(jkieber@)./cgi/doi/10.1104/pp.110.155887tion as sensors of cell wall integrity.Both WSC and MID2contain an extracellular domain rich in Ser/ Thr residues,a single transmembrane domain,and a small C-terminal cytoplasmic domain that interacts with ROM1and ROM2(Philip and Levin,2001). Upon activation,ROM1and ROM2stimulate the small GTP-binding protein Rho1,which in turn ini-tiates a variety of processes,including changes in the synthesis of b-glucan,nucleation of actinfila-ments,secretory vesicle targeting,and activation of a mitogen-activated protein kinase(MAPK)cascade that leads to changes in gene expression related to cell wall biogenesis(Ozaki et al.,1996;Levin,2005). The hypothesis that plant cells have the ability to sense and respond to changes in wall integrity is supported by the observation that genetic or chem-ical perturbation of cellulose biosynthesis results in an ectopic deposition of lignin.Lignification,which increases the rigidity of the cell wall,normally occurs in the secondary cell walls of the vascular tissue and in response to pathogen attack.Ectopic lignin deposition has been observed in several cel-lulose-deficient mutants(Vance et al.,1980),includ-ing rsw1(root swelling1),eli1(ectopic lignification), and prc1(procuste),which disrupt CESA1,CESA3, and CESA6,respectively,as well as the korrigan and fei mutants(Nicol et al.,1998;Can˜o-Delgado et al., 2000,2003;Fagard et al.,2000;Xu et al.,2008). Ectopic lignin deposition also occurs in seedlings treated with the cellulose synthesis inhibitors2,6-dichlorobenzonitrile and isoxaben(Can˜o-Delgado et al.,2003).In addition to increased lignin deposi-tion,disruption of cellulose synthesis also results in other changes,including changes in gene expression, activation of ethylene and jasmonic acid signaling pathways,and the inhibition of cell elongation(Can˜o-Delgado et al.,2003;Duva and Beaudoin,2009).These changes in cellular function indicate that the cell not only senses changes in the wall but that there is a feedback system in place to maintain cell wall integrity.Relatively little is known about the molecular com-ponents and signal transduction pathways involved in the regulation of plant cell wall function.Recent stud-ies have implicated multiple receptor-like kinases (RLKs)in cell wall signaling.RLKs represent a large (approximately600in Arabidopsis),diverse family of proteins(Shiu and Bleecker,2001)that physically link the cell wall to the cytoplasm,making them ideal candidates for cell wall sensors.RLKs are situated at the plasma membrane and contain an extracellular domain,a transmembrane domain,and an intracellu-lar Ser/Thr kinase domain.They have been implicated in various signaling pathways,including meristem function,brassinosteroid perception,floral abscission, ovule development and embryogenesis,plant defense, and overall plant morphology(Becraft,2002).This review highlights the role of RLKs in cell wall function.THE WALL-ASSOCIATED KINASESThe wall-associated kinases(WAKs)are a set of RLKs that are tightly bound to the cell wall(He et al., 1996).There arefive highly conserved WAK genes in Arabidopsis and an additional26WAK-like genes that encode proteins with divergent extracellular domains (Verica et al.,2003).The WAK proteins consist of an extracellular domain,a transmembrane domain,and a cytoplasmic Ser/Thr protein kinase domain.The ex-tracellular domains of the WAKs are40%to60% identical to each other and contain two epidermal growth factor-like repeats.This domain binds tightly to pectin in a calcium-dependent fashion(Decreux and Messiaen,2005).This association with pectinfirst occurs in an endomembrane compartment,most likely the Golgi(Kohorn et al.,2006a).The intracellular kinase domains of the WAKs are more highly con-served than their extracellular domains,which might reflect similar downstream targets;alternatively,this catalytic domain may be more evolutionarily con-strained.Allfive WAKs are expressed widely through-out the plant in the expanding cells of leaves,stems, roots,and fruits,and their expression is differentially regulated by environmental and developmental cues such as wounding,pathogen infection,and aluminum (He et al.,1998;He et al.,1999;Wagner and Kohorn, 2001;Sivaguru et al.,2003).WAKs are required for cell expansion during plant development.Disruption of WAK function using in-ducible expression of full-length WAK2antisense RNA,which likely disrupts multiple WAKs,compro-mised leaf cell expansion(Lally et al.,2001;Wagner and Kohorn,2001).Consistent with these results,root cell elongation is impaired in wak2loss-of-function mutants and in seedlings expressing WAK4antisense RNA(Kohorn et al.,2006b).The growth of a wak2 loss-of-function mutant was dependent on exogenous sugars,suggesting that the mutation may alter sugar metabolism(Lally et al.,2001;Kohorn et al.,2006b). This idea is supported by thefinding that wak2mu-tant roots show reduced vacuolar invertase activity, which is critical for the generation of solutes required to maintain turgor pressure during cell expansion (Kohorn et al.,2006b).Furthermore,both the expres-sion of INV1,which encodes an invertase enzyme, and MAPK3activity are induced in Arabidopsis mesophyll protoplasts treated with pectin in a WAK2-dependent manner(Kohorn et al.,2009).Loss-of-function mapk3mutants,which are aphenotypic, enhanced the phenotypic effects of a WAK2dominant negative transgene.Together,these results suggest that WAK2and MAPK3may be involved in a pathway that modulates the activity of vacuolar invertase by detecting pectin-based signals in the cell wall(Kohorn et al.,2009).A combination of in vitro and in vivo studies have identified a WAK1protein complex that includes a Gly-rich-extracellular protein(AtGRP-3)and a kinase-associated protein phosphatase(KAPP;Park et al.,Steinwand and Kieber2001).In plants,Gly-rich proteins are considered structural components of the cell wall(Keller,1993); thus,in addition to binding pectin,the extracellular domain of WAK1likely also binds AtGRP-3.The KAPP protein binds to the cytoplasmic kinase domain of multiple receptor kinases in a phosphorylation-dependent manner(Braun et al.,1997;Shah et al.,2002), and in several cases,this interaction has been demon-strated to be functionally relevant.AtGRP-3spe-cifically interacts with WAK1;however,KAPP binds to the kinase domains of both WAK1and WAK2as well as to the kinase domains of other RLKs.The expression of WAK1and AtGRP-3was up-regulated by exogenously added AtGRP-3protein,suggesting that they are regulated by a positive feedback loop (Park et al.,2001).Although the biological significance of the WAK1/AtGRP-3interaction has not been de-termined,the specificity of this interaction,together with the distinct expression patterns of the various WAK genes,suggest the possibility that the WAKs may sense different signals from the wall.THE CATHARANTHUS ROSEUS RLK1-LIKE FAMILY The Catharanthus roseus RLK1-Like(CrRLK1L)family is named after its founding member,CrRLK1,which was identified from the plant C.roseus(Schulze-Muth et al.,1996).There are17members of the Arabidopsis CrRLK1L subfamily of RLKs,and four of these have been implicated in regulating cell wall function: FERONIA(FER),THESEUS1(THE1),HERCULES1 (HERK1),and HERK2(Hematy and Ho¨fte,2008;Guo et al.,2009a,2009b).The FER RLK was identified by its role in pollen tube function(Huck et al.,2003).FER-dependent sig-naling in the synergid cell appears to be required for pollen tube growth arrest and the release of sperm cells in the female gametophyte during fertilization (Huck et al.,2003;Escobar-Restrepo et al.,2007).In fer mutant ovules,pollen tubes fail to cease growth and to rupture upon reaching the micropylar entrance of the embryo sac;instead,they continue to grow within the embryo sac,thus failing to fertilize the ovule(Escobar-Restrepo et al.,2007).More recent studies have demonstrated that fer mutant seedlings display a pronounced decrease in hypocotyl elongation,petiole length,and overall shoot growth when compared with wild-type seedlings,suggesting that FER also regu-lates cell elongation in these contexts(Guo et al., 2009a).The THE1RLK was identified as a suppressor of the hypocotyl elongation defect of a loss-of-function mu-tation in the catalytic subunit cellulose synthase6 (cesA6prc1).the1was found to also suppress the hypo-cotyl growth inhibition of a subset of other mutants altered in cell wall function,including cesA3eli1and cesA rsw1,and to suppress the ectopic lignin accumula-tion observed in these cellulose-deficient mutants. However,surprisingly,the1did not suppress the defect in cellulose biosynthesis of the cesA6prc1mutant. These results suggest that the inhibition of hypocotyl elongation and the ectopic lignin deposition in the cesA6prc1mutant is an active response to cell wall de-fects that requires signaling through the THE1recep-tor.Consistent with this,transcriptional profiling identified36genes that were altered by cesA6prc1in a THE1-dependent manner.The THE1-dependent genes included two transcription factors,several proteins involved in protecting the cell against oxidative stress, potential pathogen defense proteins,and multiple genes encoding cell wall proteins(Hematy et al.,2007). Single loss-of-function mutations in THE1in an otherwise wild-type background did not result in any detectable change in plant growth and develop-ment(Hematy et al.,2007),suggesting that THE1 function is only revealed when the cell wall is per-turbed.However,recent studies have shown that THE1 is genetically redundant with other members of the CrRLK1L gene family,as combining the1with herk1 and/or herk2mutations,single mutants that are also aphenotypic,resulted in strong effects on cell expan-sion,including decreased petiole length and shoot growth(Guo et al.,2009a,2009b),similar to the effects of the fer mutation.The overall decreased growth in the double the1herk1mutants was found to be a consequence of reduced cell elongation,implicating these RLKs as important regulators of cell expansion within the cell wall.Interestingly,six of the17CrRLK1L genes are regu-lated by brassinosteroid,including THE1,HERK1, HERK2,and FER(Guo et al.,2009a,2009b).Further-more,the herk1the1mutations enhanced the dwarfed phenotype of the loss-of-function brassinosteroid re-ceptor mutant,bri1,and partially suppressed the ex-cessive cell elongation phenotype of a gain-of-function bes1-D mutant(Guo et al.,2009a).Expression profiling of the the1herk1double mutant and the fer single mutant suggests that these receptors regulate over-lapping sets of genes.Furthermore,16%of the genes affected in these mutants are regulated by brassino-steroid.These data suggest that while THE1,HERK1, HERK2,and FER may act in a common pathway re-quired for cell elongation,there is cross talk between this pathway and the pathway mediating brassinosteroid-regulated cell elongation.The reduced cell expansion observed in the the1/herk multiple mutants atfirst seems at odds with the increased cell expansion brought about by the the1 mutation in the cesA6prc1background.One simple model to resolve this apparent discrepancy invokes a threshold mechanism:the reduction in THE1/HERK signaling resulting from single the1mutations is enough to disrupt the feedback system involved in perception of the altered cell wall function of the cesA6prc1mutant,but it is not drastic enough to sub-stantially alter basal cell wall synthesis.In contrast, further disruption of this class of receptors(i.e.the the/ herk multiple mutants)decreases signaling below a threshold necessary for proper regulation of cell wallReceptor-Like Kinases and the Cell Wallsynthesis even in basal conditions.The cell must maintain a delicate and dynamic balance between wall rigidity and extensibility during growth;thus, perturbing this proposed feedback system to differ-ent levels could shift this balance with distinct out-comes.THE LEU-RICH REPEAT RLKSThe leucine-rich repeat(LRR)RLK family represents the largest group of RLKs encoded by higher plant genomes.The Arabidopsis LRR-RLK family is com-posed of216genes distributed among13different subfamilies(Shiu and Bleecker,2001).In animals,LRR proteins are important signaling components of many developmental and host defense pathways.However, unlike in plants,animal LRR proteins do not contain a cytoplasmic protein kinase domain but instead trans-duce signals across the plasma membrane by activat-ing coreceptors,a mechanism that may be conserved in plants.Recently,two LRR-RLKs(FEI1and FEI2)were dem-onstrated to play a role in the regulation of cell wall function.Although single fei1and fei2mutants showed no obvious phenotypes,double fei1fei2mu-tants displayed conditional root anisotropic growth and ectopic lignin deposition.These phenotypes are characteristic of cellulose deficiency;indeed,fei1fei2 mutant roots displayed a significant decrease in the synthesis of cellulose and possibly other cell wall polymers when grown in nonpermissive conditions, suggesting that the FEI receptors regulate the synthe-sis of cell wall components(Xu et al.,2008).The sos5 mutant,which was isolated as a mutant that displayed a swollen root tip in the presence of moderately high salt(Shi et al.,2003),was found to have a similar phenotype to fei1fei2.Genetic analysis revealed that SOS5and the FEIs act through the same pathway to regulate cell wall function(Xu et al.,2008).SOS5 encodes a cell surface glycosylphosphatidylinositol-anchored protein with fasciclin-like domains(Shi et al.,2003)and could act as,or may be involved in the production or presentation of,a FEI ligand.Both the fei1fei2and sos5mutants display swollen root phenotypes only when elevated levels of Suc or salt are present in the medium,which is also observed in several other root-swelling mutants,including cesA6prc1,weak alleles of cobra(Xu et al.,2008),and pom1and pom2mutants(Hauser et al.,1995).This sug-gests that elevated levels of Suc or salt sensitize roots to perturbations in cell wall synthesis through an as yet unknown mechanism.It has been suggested that the Suc-dependent phenotype of cobra and several other root-swelling mutants could be linked to the relative rate of root growth,with defects occurring only under conditions of maximal growth rates(Hauser et al., 1995).However,fei1fei2(and sos5and weak cobra alleles)also display swollen roots on medium con-taining moderately elevated levels of NaCl(Xu et al.,2008),a condition that decreases the rate of root growth.Further analysis indicated a role for1-aminocyclo-propane-1-carboxylate(ACC)synthase,which cata-lyzes the rate-limiting step in ethylene biosynthesis,in FEI function.Both FEI1and FEI2directly interact with ACC synthase,as shown by yeast two-hybrid assays. Furthermore,inhibition of ACC function using either a-aminoisobutyric acid(AIB;a structural analog of ACC)or aminooxy-acetic acid(inhibits ACC synthase) reverted the root-swelling phenotype of both the fei1 fei2and the sos5mutants.As aminooxy-acetic acid and AIB block ethylene biosynthesis by distinct mecha-nisms,it is unlikely that this phenotypic reversion of fei1fei2is due to off-target effects of the inhibitors. Furthermore,this is not a general effect of AIB,as it did not revert the root-swelling phenotype of the cobra mutant(Xu et al.,2008).Surprisingly,inhibition of ethylene perception via mutations or chemical inhib-itors had no appreciable effect on the root phenotype of fei1fei2or sos5-2mutants(Xu et al.,2008).This suggests that either swelling in the absence of FEI depends on a hitherto undiscovered pathway for ethylene perception or that ACC itself is acting as a signaling molecule.Consistent with this hypothesis, recent data indicate that,in addition to acting as the immediate precursor to ethylene,ACC itself may also act as an essential regulator of plant growth and de-velopment(Tsuchisaka et al.,2009).Genetic disruption of all eight ACC synthase genes in Arabidopsis caused embryonic lethality,in contrast to mutations that elim-inate ethylene perception,such as etr1and ein2,which have only relatively modest effects on plant develop-ment.The precise role of ACC in plant development in general and in the FEI pathway specifically,and how this potential signaling molecule is perceived, are important questions that need to be addressed.CONCLUSIONWhile the identification of multiple RLKs that likely play a role in regulating cell wall function is an important beginning in our understanding of cell wall signaling,thefield is only in its infancy and many questions remain unanswered.There are over 600RLKs in Arabidopsis,and it is likely that addi-tional RLKs play a role in regulating wall function.To further enhance our understanding of this signaling system,it is crucial to identify the immediate targets of the RLKs implicated in cell wall function.One poten-tial target could be the cellulose synthase enzyme itself,as multiple phosphorylation sites have been identified,clustered primarily in the N-terminal do-main of several CESA proteins(Nuhse et al.,2004; Brown et al.,2005;Persson et al.,2007),and phosphor-ylation of CESA7has been linked to its degradation via a26S proteasome-dependent pathway(Taylor, 2007).However,an intact kinase catalytic domain is not required for the function of FEI1/FEI2(Xu et al.,Steinwand and Kieber2008),raising the possibility that,at least for this class of RLKs,the targets may not be regulated solely by phosphorylation.How these RLKs interact with each other and with other signaling pathways to regulate cell wall function is unknown.Finally,while pectin has been identified as a possible ligand for the WAKs, there are no clear candidate ligands for the other RLKs. The near future will likely reveal answers to these and other questions,and perhaps an integrated model describing the mechanisms by which cell walls per-ceive and respond to signals will emerge.ACKNOWLEDGMENTSWe thank Smadar Harpaz-Saad and Tracy Hargiss for helpful comments on the manuscript,and we apologize to those many authors whose work was not cited owing to space limitations.Received March5,2010;accepted April14,2010;published April21,2010.

Research on Controls-Based Visual ProgrammingYubin Liu 1Yellow River Conservancy Technical Institute,Kaifeng ，China 475003 e-mail: hhsylyb@Li Wu 2and Xinfa Dong 3Yellow River Conservancy Technical Institute,Kaifeng ，China 475003 e-mail: kaifengqzh@Abstract --The current programming environment only implements the visualization programming of the software interface. The process of programming is not fully visualization; programmers still need to input codes line by line. And the current programming languages are not the visual programming language in the true sense. If the programming language is made up of series of graphic expressions, then it is under the name of visual programming language. This paper provides a new kind of visual programming language UVPL （Uniform Visual Programming Language ）. It makes the visual components as grammar cells, and constitutes a series of visual sentences in accordance with predetermined grammar rules. Then it can be able to automatically generate the text codes, and to generate the designated codes in other existing languages such as C, Java or Pascal, the whole Encoding Process is visual. It reduced morphology and syntax error rates, shortened the debugging time, improved the development efficiency.Keywords--Control; visual; programming language; programming environment; visual expressionsI.INTRODUCTIONAccording to the present programming development environments, they usually take beginners a long time to complete a program. This is partly because they need to understand the new concepts, syntax, and semantics of a programming language. However they often spend a lot of time editing a program andcorrecting types and misspellings, according to our survey, when they use a text programming language many novice programmers are not used to touch typing (especially their native language is not English) or operate a text editor or conventional integrated development environment (IDE) system. We think that this situation greatly affects them not only at their programming efficiency but also theirunderstanding of the programming concepts [1].Visual programming language (VPL) is any programming language that lets users program graphically with elements rather than textually [2]. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols [3][4]. II.OVERVIEW OF USING CONTROLS TO EXPRESS LANGUAGE ELEMENTS OF THE HIGH-LEVEL PROGRAMMINGLANGUAGEAccording to many articles, there are a variety of researches on visual programminglanguages and development environments, I generally put them into two categories [5], one is against the actual demand in some visual development environment, in particular to meetthe robot development, game development and industrial controls products. Such as: LabView, Comikit, Visual Gragh and MVPL (Microsoft Visual Programming Language). Another is a response to visual development environment and the development of a graphical high-level language, such as the visulan.2010 Second International Conference on MultiMedia and Information TechnologyRecently, I always think about the topic of "software as building blocks" and the desire for non-programmers to be able to assemble these blocks into something that met their needs came up. So I think about that we should develop enough controls to express language elements of the high-level programming language. I found these kind of programming languages really elegant and fun to use, especially with the ability to write your own modules if something you needed and it didn't exist. So. I want to apply this programming method to an interesting problem in a way that empowers individuals to "program" by just dragging out controls and setting their attributes, and seeing the results in real-time. When we drag or edit a control there is a text file generated. After we finish our program, the corresponding text file is also generated. And last, when we compile the program, in fact it compiles the text files. Because according to the present, compile a text file is more efficient than compile a graphical file according to now compiler. Of course you can make the text file and the controls to be showed as C#[6] style, pascal style or java style etc.So first we should define a new visual programming language, And then we begin our visual programming based on it. For simplicity of reasoning, we introduce a primitive version of the language named UVPL (Uniform Visual Programming Language).III.IMPLEMENTATION OFCONTROLS-BASED VISUALPROGRAMMINGA.Data StyleIn order to reduce the workload and maintain the essence of a new visual language UVPL, we assume that it only contains some of the basis data style: integer, real, string and Boolean.B.Basic ControlsThe present development environments, such as visual studio 2005/2008 or Delphi 2006/2009, are conductive to the development of controls. Each control has a group of properties and events for options and modifications. Besides some basis properties of the controls such as visible, I take into account some important properties as follows:•Revealed a set of properties and methods enough for developers.•Controls with properties can be persistent.•Controls can be released and reusable.•The appearance of control can be expressed with Multi-lingual format.Programming with controls has nothing to do with generating a specific language text file, this is my aim. In order to a high readable as text file, the controls can be showed as c# or Pascal etc, and the final program also can appear all kinds of high-level language style such as c#, Pascal or java etc.According to the design of the UVPL, we developed 9 controls as the basic grammar cells. And we can compose complex statements, function, or program with them. They are Program Begin, Reserved words, Constant define, Variable declaration, Assignment statement, Input output, IF statement, WHILE statement, Program end. The 9 controls are showed as Fig1.Fig1-UVPL basic controlsAs for the variable declaration, for example, we developed a corresponding control just as Fig2.Fig2(a)-variable-attributeFig2(b)-variable-Pascal styleFig2(c)-variable-C# styleWe can set the controls appearance as one style which we like. The complex expressions or statements are composed of the basis expression and statements, but we should think about the problem of nested control. And the internal parts in it are some expressions, thus we should deal with the problem of Nested controls. When we edit a specific expression, we should click the expression control so as to choose it, and then the corresponding attributes form will popup or list just as that in the development environment of Microsoft visual C# 2008 [8], for example, when we define a constant, we will choose its type, just as fig3Fig3-consttype-attributeC.Integrated Development EnvironmentWe developed a simple IDE, it has a basic controls toolbox with 9 controls which we just descript, and has a Property Bar in its right,showed as Fig4.Fig4 UVPLE-sampleIn this simple UVPLE, we just drag the controls in the left basic ControlsToolbox, placed them from top to bottom.And set the controls properties in theright Property Bar. A complete sample asFig5.Fig5 UVPLE-sampleIn this sample, all statements are controls which were dragged out from the Basic Controls Toolbox. No one line text or letters in it. It is truly the visual programming, and compliance “WYSIWYG(what you see is what you get)”, the principle of ideological programming in a bid to realize the visual programming, the results can be seen at any time, procedures and theresults of the simultaneous adjustment ,which can meet the development of a general abstract sense, it is the visual programming graphical development. Controls-Based visualprogramming is a new programming change, which combines object technology and components technology. We can use its basic controls as the visual morphemes to express the abstract methods such as algorithms [7]. When we drag or edit a control to do our program, there is a text file generated automatically. And we can choose a text file type to save, just asFig6Fig6 UVPL-testIV. DISCUSSIONS AND FUTURE WORK In order to perfect this visual programmng, we have a lot of work to do. The definition of it should be detailed and whether the basic controls are enough to express the program work perfectly. Finally, we will finish developping many controls Corresponding to IF-THEN-ELSE structure, FOREACH structure, solve the Nested controls problems, and complete the development environment.REFERENCES[1] Noritaka OSAWA, Kikuo ASAI, Yuji Y .

Status Quo in the Three Quarters of 2010 Wang Ting【摘要】@@ In general rnGenerally speaking,in the first three quarters of 2010,the main industrial operation index still kept an increasing trend,but the growth margin represented a slower uptrend.【期刊名称】《中国纺织（英文版）》【年(卷),期】2010(000)011【总页数】4页(P22-25)【作者】Wang Ting【作者单位】【正文语种】中文In generalGenerally speaking, in the first three quarters of 2010, the main industrial operation index still kept an increasing trend, but the growth margin represented a slower uptrend.During the first nine months of 2010, the total industrial output realized a growth of 26.04%, with the growth speed increasing by 18 percentage points comparing with the same period of time of 2009, while the saleswitnessed a year-onyear increase of 26.36%.In terms of different textile p r o d u c t s, f r o m J a n u a r y t o September, the output of the manmade fiber increased by 14.25%, up by 0.16 percentage points comparing with the same time of last year; the growth speed saw a continuously downtrend from April to July, however, it rebounded slightly since August.The industrial output of yarn, fabrics, and apparel in the f rst nine months represented a growth of 16.09%, 17.67% and 18.24%, increasing by 5.69, 15.44 and 13.25 percentage points, year-on-year, respectively. Generally speaking, the growth speed of most industrial textile products began to see an uptrend in the f rst three quarters of 2010.The dom e sti c sal es still performed as one of the pillars driving the development of textile and apparel industry in China: from January to September, the domestic consumption increased by 28.8% year-on-year, up by 16.65 percentage points comparing with the same period of last year; furthermore, the proportion taken by domestic consumption reached 81.14%, which rose by 0.15 percentage points comparing the same time of 2009.Comparing with other categories, the retail sales of apparel in domestic market grew fast: in the firs nine months, the retail sales of consumer goods increased by 18.3%, while the sales of apparel rose by 24.0%, 5.7 percentage points higher than the social average level.Prof tThe rising cost is an inevitable problem for the textile and apparel industry in China. According to the statistics, it is estimated that since the October 2009, the cost price index of the textile industry represented an uptrend markedly. Till the September, 2010, the textile industrial cost price index reached 125.39.Of them, the cost price index of the raw material increased by 28.56%, the price of yarn, fabrics, and ex-factory price rose by 41%, 20% and 1.8% year-on-year, respectively.From January to August, the industrial total profit witnessed a rise of52.42%, however, the growth speed down by 40.14 percentage points year-on-year. In terms of different industries, the cotton industry stood ahead among other industries: in the f rst eight months, the cotton industry realized a prof t of 37.075 billion Yuan, with a rise of 66.45%, and the growth speed ascending by 40.14 percentage points.Then, followed by the apparel and MMF industry: from Jan. to Aug., the total profit of apparel and MMF industry reached 34.533 billion Yuan and 14.277 billion Yuan, ascending by 30.92% and 103.38%, respectively. InvestmentDuring the first three quarters, the actually-realized fixed assets investment increased by 25.66% year-on-year, rising by 16.95 p e r c e n t a g e p o i n t s comparing with the same period of time of last year. The newly-launched projects witnessed a rise of 11.26% comparing with the same period of last year, down by 10.32 percentage points. Of the whole textile industry, the wool and MMF industry realized the highest investmentcomparing with other industry, with a growth speed around 50% markedly.Moreover, in terms of regions, the investment to the middle and western part of China saw a sharp increase: from Jan. to Sep., the investment in the middle and western regions rose by 42.61% and 56.12%, respectively, which are 29.98 and 43.49 percentage points higher than that in the eastern part of China.Besides, the proportion taken by the middle and western regions of the whole investment reached 36.12% and 9.95%, increasing by 4.29 and 1.94 percentage points respectively year-on-year.ExportAccording to the Customs, from Jan. to sep., the total export of textiles and apparel reached 149.820 billion USD, with a rise of 23.14% year-on-year, and up by 34.25 percentage points comparing with the same time of 2009. Moreover, in the first nine months, the export in July arrived at the highest value among others months, along with August and September, the export in each month was above 20 billion USD, respectively.Comparing with apparel, the growth s p e e d o f t h e export of textiles represented a fast increase during t h e f i r s t e i g h t months. Accordingto statistics, from January to August, t h e e x p o r t o f textiles and apparel accumulatively rose by 32.23% and 19.02%, with the growth speed ascending by 46.27 and 29.1percentage points comparing with the same period of 2009 respectively.In terms of countries and regions, from Jan. to Aug., due to the rebounded consumption market in USA, the export to USA represented a sharp jump. Since 2010, the sales in American market show a fast increasing: from January to August, the sales ascended by 5.94%, with the growth speed up by 15.02 percentage points comparing with the same time of 2009. Of them, the retail sales of apparel increased by 4.26%, with the speed increasing by 11.20 percentage points year-onyear.According to the statistics, the export to USA rose by 30.63% comparing with the same time of last year, and the growth speed ascended by 30.70 percentage points. Not only the export amount saw a growth, but also the exported price witnessed an increase during the f rst three quarters: from January to August, the export amount to USA rose by 29.08% year-on-year, with a growth speed rising by 20.09 percentage points; while the price index up by 10.34 percentage points comparing with the beginning of 2010.Meanwhile, the export to EU ascended by 21.28% year-on-year, with a growth speed up by 30.05 percentage points; while, the export to Japan also increased slightly: during the first eight months of 2010, the export only increased by 2.77%, with a growth speed rising by 1.86 percentage points year-onyear.Furthermore, in terms of different categories of the countries, the export to the developing countries grew faster than that of the developed countries: from January to August, the export to developing countries rose by29.47%, and the growth speed was 9.98 percentage points higher than that of the developed countries (which saw a rise of 19.49%).The export to the Association of South East Asian Nations still represented an obviously increase: from January to August, the export saw a fast rise of 40.74% year-onyear.Main Industrial Index for 2010(Above-designated sized enterprises)Main industrial index Accumulative Amount ±% Output for main industrial products Accumulative Amount ±% Total Income (100 million Yuan) 44500 24 MMF (10,000 tons) 3030 13 Total Prof t (100 million Yuan) 2050 40 Yarn (10,000 tons) 2730 14 Total Output (100 million Yuan) 45500 23 Fabrics (100 million meter) 632 14 Total Export (100 million USD) 2060 20.5 Apparel (100 million piece) 274 17tForecastThere are also several domestic as well as overseas factors influencing the development of extile and apparel industry in China, such as the currency exchange rate, soaring price for production factors, and so on.Currency exchange rate would be one of hot issues for textile industrial export and import in China during this year, creating tough pressures forthe textile, especially exported textile and appeal, enterprises in China. . Besides, various reasons make the cotton price soar so fast; since this September, the price has already stepped to the highest level in ten years. Recently, in the new cotton year, the cotton supply in domestic and global market represented a sigh of tightening, so that the cotton price in a short term could not be easily adjusted.As the raw material price was stable, in 2010, the MMF price was favorable correspondently. However, due to the fast increasing cotton price, since this September, the price of MMF show an uptrend.Furthermore, the price of employees also represented a fast rising trend: in the first half year, the employee’ welfare per person of the manufacture industry increased by 14.9%. It is estimated that the textile industrial labor price would keep a growth around 15%.Nevertheless, the fluctuant currency exchange rate would b e c o m e o n e o f t h e m o s t important elements influencing the industrial export in China, which would affect the growth margin of the export slightly. The strong domestic demand and the active domestic consumption would support the favorable development of the whole industry, leading the industrial growth speed preserve a stable situation. The soaring high price of the raw material would increase the cost burden for the middle and downstream textile and apparel enterprises, so that the total prof t would be affected inevitably.。
