Such design often results in spaces that do not meet the needs of users. The purpose of this paper is to investigate the process and way of generating design parameters by constructing a BP neural network algorithm for spatial design. From the perspective. This paper adopts an experimental research method to take a kindergarten with a large number of complex needs in space as the object of study, and through the BP neural network algorithm in machine learning, the correlation between environmental behavior parameters and spatial design parameters is imprinted. The way of generating spatial design parameters is studied. In the future, the corresponding spatial design parameters can be derived by replacing specific environmental behavior influence factors, which can be applied to a wider range of scenarios and improve the efficiency of designers.","PeriodicalId":45879,"journal":{"name":"Journal of the Korean Chemical Society-Daehan Hwahak Hoe Jee","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48434373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such incidents come as big problem because various policies and programs have widely long been implemented in order to protect the school environment. Thus, it is critical for the local community and goverment to develop measures for prevention. However, some of the incidents are misrepresented because school environment still remains as one of the safest settings. The current study discusses successful case studies of education, policies and projects regarding school violence and safety that are enforced in many other nations. One of the most practical and concrete means of pursuing an improved level of school safety is for the local community to be actively involved in the process. And one of the key factors for the success of international programs was that it was very much an integrative approach involving a joint effort with the local communities, accompanying a strong tie between the school and its surrounding context.","PeriodicalId":45879,"journal":{"name":"Journal of the Korean Chemical Society-Daehan Hwahak Hoe Jee","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43470346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, we collected unstructured data of consumers in portal sites and online markets using web crawling, and analyzed meaningful information about products through preprocessing for transformation of standardized data. The datasets of 11,200 were analyzed by Logistic Regression to analyze consumer satisfaction, frequency analysis, and advantages and disadvantages of products. The result of analysis showed that the satisfaction of consumers was 92% and the defective issues of products were confirmed through frequency analysis. The results of analysis on the use satisfaction, system efficiency, and system effectiveness items of the developed product planning prediction program showed that the satisfaction was high. Defective issues are very meaningful data in that they provide information necessary for quickly recognizing the current problem of products and establishing improvement strategies.","PeriodicalId":45879,"journal":{"name":"Journal of the Korean Chemical Society-Daehan Hwahak Hoe Jee","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46169675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DOPC has three different conformations according to glycerol C1C2 bond: A(θ3 = trans, θ4 = gauche), B(θ3 = gauche, θ4 = gauche-), C(θ3 = gauche-, θ4 = trans). Changes in the glycerol backbone structure of the DOPC were examined using the solvent’s dielectric constant and surface tension constant as variables. As a result, the population of the B structure increased as the dielectric constant increased. The reason is that the solvation energy of the B structure is larger than that of A. In addition, as the surface tension constant increased, the population of the B structure increased because the surface area of B was smaller than that of A. The results of these studies are expected to be used in the study of phospholipid structure in the future.","PeriodicalId":45879,"journal":{"name":"Journal of the Korean Chemical Society-Daehan Hwahak Hoe Jee","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47652859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
