The pharmaceutical industry has an ongoing need for new, safe medicines with genuine biomedical effects. Most of the candidate molecules are far from becomes a drug, because of their pharmacokinetic and pharmacodynamic properties. The introduction of bioisostere to improve properties of molecules and to obtain new class of compound is currently increased. Silicon substitution of carbon of existing drugs is an attractive strategy to search a new candidate with improved biological and physicochemical properties. The fundamental differences between carbon and silicon can lead to improved profile of the silicon containing candidate, and could be exploited to get further benefit in drug design process.

Supplier quality management (SQM) is considered as a proactive approach in the buyers' perspective to seek for continuous supply quality improvement and collaborative ongoing alliance between buyers and suppliers. Therefore, it is important for the buyers to understand their circumstances for managing their suppliers, and thereby to search for an improved way to rectify managerial deficiencies, if any. This paper aims to identify the critical factors of SQM, and then propose a hierarchical framework which can facilitate the assessment of their SQM performance in the buyers' perspective and also serve as a working tool for managing supply quality performance.

As a part of an ongoing search for natural plants with antioxidant compounds by measuring the radical scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH), a total extract of the aerial parts of Bidens frondosa L. (Compositae) was found to show potent antioxidant activity. Subsequent activity-guided fractionation of the methanolic extract led to the isolation of five compounds, quercetin-3-O-${\beta}$-D-glucopyranoside (1), luteolin-7-O-${\beta}$-D-glucopyranoside (2), 7,8,3',4'-tertrahydroxy-flavanone (3), okanin-4-O-${\beta}$-D-glucopyranoside (4), and okanin (5). Their structures were elucidated by spectroscopic studies. Compounds 3-5 were isolated for the first time from this plant. Among them, compounds 3 and 5 showed the significant radical scavenging effects on DPPH, and compounds 3 and 5 also showed the potent riboflavin and xanthine originated superoxide quenching activities.

Objectives: The purposes of this study were to describe comprehensive health promotion policies for university students in Korea and to discuss the implications based on the socio-ecological approaches. Methods: A web-based search was performed to identify empirical programs and literature to develop health promotion policies and strategies in university settings. Results: Five domains for policy development are suggested for comprehensive health promotion policies in universities: evidence-based policy development; establishment of supportive policy through network and partnership; infrastructure of university; systems approach with education, environment, enforcement and policy tailored for universities; and sustainability for policy implementation. Conclusions: For healthy universities and students, government, community, health professionals, organizations and universities are all responsible as main agents for the five domains suggested in this study. Multi-level approaches with political, organizational and environmental changes should be sustained as an ongoing process.

This paper reports on an ongoing study investigating the feasibility of using an evolutionary method to develop the rules governing Self-Organised (SO) systems for use in swarms of unmanned aerial vehicles. In general, it is difficult to design swarm systems that follow explicit global behaviour. Unlike optimising a predefined objective function, the solution to the problem is the emergent behaviour in the SO systems which results from simultaneous interactions among agents and between agents and their environment. In this study, evolutionary algorithms are used to investigate their control and effectiveness in synthesising the weighting of different rules on SO emergent behaviour. Both homogeneous swarms and heterogeneous swarms were considered though the results provided are for a case study investigating the simplest problem a homogeneous swarm without mutation. Though simple this study does indicate the potential of the approach.

The combination between metaverse and non-fungible token (NFT), which opens up new opportunities for the media industry, raised expectations for a new economic system and business model. Of course, last year, various institutions and researchers continuously introduce representative metaverse services and business strategies such as Roblox, Fortnite, and ZEPETO. However, as 2022 progresses, the reaction to the metaverse is tepid than expected. Search volume on Google has been continuously decreasing. Furthermore, skepticism, regarded as one of the special phenomena caused by the coronavirus disease 2019 pandemic, is expanding since December 2021. Nevertheless, analysis or contemplation of a new business model related to the metaverse, which is still ongoing, is essential for those who must prepare for the future. The reason is that even if without being activated now, advanced preparation can help when various problems arise. In this study, we look at the metaverse and NFT biz models and estimate a picture of the future. In other words, the social and economic problems that may arise when the business model is expanded are summarized, and technical and policy measures are derived as solutions.

It is not easy to go on business. Many businesses are fails for many reasons. The purpose of this research was to study ongoing business intention of entrepreneurs that were related to the business burdens such as economic loss, psychological stress, bankruptcy and other failure stresses. To study this search, wide surveys were conducted targeting entrepreneurs of small and medium size companies. About 300 research papers were distributed and 260 papers were collected and 247 questionaries were used for final analysis. And SPSS 24.0 programs were used. The results of this study were as follows. First, the entrepreneurial intention was closely related to the debt burdens. If the burdens of debt were high, ongoing entrepreneur intention went down. Second, the recognition of bankruptcy systems gave positive impacts for the entrepreneurs of small and medium size companies. Third, among the psychological costs, the intention of business stop gave negative impacts to ongoing business intention. There are many obstacles and difficulties in real business world. Especially in Korea failure costs are considered to individual costs and responsibilities. However, countries such as U.S., E.U. and Israel, the costs of failures considered to social costs. According to this study, burdens related to business failure were closely related to entrepreneur intentions. Therefore, the implications of this study are diverse solutions to easy business burdens are necessary.

The purposes of this study were 1) to test the differences between two groups who have high and low purchase of apparel in low-price retailing concerning consumers' beliefs and attitude toward low-prce retailing 2) to identify differences between these two groups in type of information search and use of information sources and 3) to investigate differences between department store and low-price retailing in consumers' satisfaction toward products and purchase frequencies of apparel items and differences between two groups in demographic variables. The data were collected via a self-administeered questionnaire from 474 femail adults in Seoul Korea and analyzed by factor analysis t-test and paired t-test. The results of this study were as follows : First based on a series of t-test and paired t-test. the results showed that those who had a high purchase of apparel in low-price retailing had significantly higher belief scores on all of the five store attributes and a more favorable attitude toward low-price retailing than did those who had low purchase. Second those who had high purchase of apparel in low-price retailing had significantly higher scores on ongoing and prepurchase information search and on use of mass media information and interpersonal information source than did those who had low purchase. Third in case of high purchase consumers of apparel in low-price retailing there were not found significant differences between department store and low-price retailing there were not found significant differences between department store and low-price retailing in purchase frequency on man's and women's casual wear of department stores than low-price retailing. However low purchase consumers of apparel in low-price retailing revealed significantly higher purchase frequency on all of seven apparel items of department stores than low-price retailing. Finally there were significant differences between two groups in demographic variables. The papers discussed theoretical implications as well as manageral implications.

Complex diseases such as stroke and cancer have two or more genetic loci and are affected by environmental factors that contribute to the diseases. Due to the complex characteristics of these diseases, identifying candidate genes requires a system-level analysis of the following: gene ontology, pathway, and interactions. A database and user interface, termed StrokeBase, was developed; StrokeBase provides queries that search for pathways, candidate genes, candidate SNPs, and gene networks. The database was developed by using in silico data mining of HGNC, ENSEMBL, STRING, RefSeq, UCSC, GO, HPRD, KEGG, GAD, and OMIM. Forty candidate genes that are associated with cerebrovascular disease were selected by human experts and public databases. The networked cerebrovascular disease gene maps also were developed; these maps describe genegene interactions and biological pathways. We identified 1127 genes, related indirectly to cerebrovascular disease but directly to the etiology of cerebrovascular disease. We found that a protein-protein interaction (PPI) network that was associated with cerebrovascular disease follows the power-law degree distribution that is evident in other biological networks. Not only was in silico data mining utilized, but also 250K Affymetrix SNP chips were utilized in the 320 control/disease association study to generate associated markers that were pertinent to the cerebrovascular disease as a genome-wide search. The associated genes and the genes that were retrieved from the in silico data mining system were compared and analyzed. We developed a well-curated cerebrovascular disease-associated gene network and provided bioinformatic resources to cerebrovascular disease researchers. This cerebrovascular disease network can be used as a frame of systematic genomic research, applicable to other complex diseases. Therefore, the ongoing database efficiently supports medical and genetic research in order to overcome cerebrovascular disease.
