In the past, designers relied primarily on past experience and reference to industry standard thresholds to design spaces. 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.

Recent accidents in school environment involving violence, and bullying indicate that school safety is exposed to a serious threat to community well-being. 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.

This study was conducted to propose a product planning prediction model using logistic regression algorithm to predict seasonal factors and rapidly changing product trends. 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.

In this study, the molecular dynamics simulation of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) single molecule was conducted by changing the solvent properties in order to investigate the change in the glycerol backbone structure in phospholipids according to the solvent properties. 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.

The purpose of this study was to investigate the effects of career maturity major satisfaction, self-control on university students' job stress. Data collection was conducted from November 2018 to February, 2019 in 236 students who understood the purpose of the study and agreed to participate in the study. The collected data were analyzed by frequency, mean, standard deviation, Pearson correlation analysis, and multiple regression. The lower the career maturity (β=-.258), job stress was the higher. Also, the lower major satisfaction (β=-.377), the higher the job stress, and the lower the self-control (β= -.275), the job stress was the higher. Through these results, education programs that link students from their childhood to college students are needed to improve their career maturity, satisfaction with majors and self-control(r=-.410, p<.001).
