At the 21th century management environment with the emotion and creativity, as design has recognized the core element of management strategy, the combination of design and management, design management, has been increased the importance worldwidely. In the rapid changing enterprise environment, the small or venture enterprises in flexible management environment than the large enterprise have advantage on management process. The design management has created the various field of knowledge in the integrated solution, the integrated approach methods of management are the effective operative process in the importance of design management. As CEOs in small/venture enterprise take part in the innovation of design management, a specialistes in recognition of specificity and design management are defined and created the design management process through the enterprise resource planning programs. With the understanding on the above situation, the purpose of this study is to suggest the design is strategically applied in the management level of Daejeon region small/venture enterprises and the recognition of design management as a strengthen the competitiveness.

This research examines the constitutional meaning of the right to health through reviewing the decisions of the Constitutional Court and proposed amendment of the Constitution issued by the President. This article further discusses the relationship between the right to a humane livelihood and the right to health. Health is a fundamental freedom and inalienable human right which is a prerequisite to accomplish individual's independent activity and realization of value. Thus, the government is obligated to protect and uphold the right. Article 36(3) of the Constitution delineates the government's duty to protect and fulfill the right to health. Through the interpretation of both Article 36(3) and Article 34 of the Constitution, I suggest that the right to health implies 'the right to social security for health'. The Constitutional Court has narrowly interpreted the scope of the right to a humane livelihood by defining the term as "minimum material living standards". However, it should be interpreted as 'the right to enjoy a healthy and cultural life for human dignity' and setting the level of protection is solely on the discretion of the legislative branch. Ultimately, the judicial review on the right to a humane livelihood connects with the issue of rational control for legislative discretion.

For this study, we carried out a field survey on the analysis for the spatial distributions of phytoplankton community in the eleven areas of the Korean South Sea during the early summer of 2018. The results from the study showed that the phytoplankton community consisted of 56 genera and 105 species showing by diatoms with 52.4%, dinoflagellates with 40.0% and other phytoflagellates with 7.6%. The cell density of the phytoplankton ranged from 5.5 to 593.2 cells mL^-1. The species number and cell density of the phytoplankton were high in the eastern waters of the South Sea and low in the western one. The phytoplankton community showed the characteristics of being dominated by the diatoms except in the Geumpo of Namhae, Ocheon-dong of Yeosu and Oenarodo of Goheung. The dominant species of the phytoplankton community were the centric diatoms, Skeletonema costatum-like species (ls), except for the Ocheon-dong and Chungdo of Wando. However, the Ocheon-dong was dominated by toxic dinoflagellate, Gymnodinium catenatum by 41.1% dominance. On the other hand, Keumpo and Oenarodo was by dinoflagellate, Tripos fusus more than 12% dominance in the surface layer. The spatial distribution of the phytoplankton community in the coastal waters of the Korean South Sea in the early summer were determined by the supply of nutrients through precipitation.

The objective of this study is to develop the design criteria of traffic island considering pedestrian level of service (LOS). In pursuing the above, this study gives particular emphasis to suggesting the minimum design space of traffic island in order to maintain pedestrian LOS C and D, and the critical pedestrian traffic volume that reflects the intersection geometry (2 lanes per direction) through the simulation analysis. The main results are as follows. First, the spaces of 160 traffic islands, which meet the pedestrian LOS C and D and reflects the pedestrian traffic volume by signal cycle, are drawn by using a commercial simulator VISSIM. The relevant spaces of traffic island in terms of both the pedestrian LOS and the pedestrian traffic volume are evaluated to range from $3.0m^2$ to $41m^2$. Second, the critical pedestrian traffic volume for the operation of traffic island is evaluated to be 1,000-1,300 person/hour at LOS C and 1,600-1,800 person/hour at LOS D, respectively, when a cycle of 120-150 seconds were applied to a intersection with two lanes per direction.

Previous studies report that organo-sulfur compounds derived from garlic inhibited smooth muscle cell (SMC) proliferation and induced apoptosis of cancer cells. Recently, lipid-soluble compounds such as diallyl sulfides (DAS) and diallyl disulfides (DADS) have been reported to more effectively suppress tumor cell proliferation. However, there were few studies on the suppressive effects of lipid-soluble garlic sulfur compounds on the proliferation and migration of vascular smooth muscle cells (VSMC). Therefore, this study investigated the effect of DAS and DADS on VSMC proliferation/migration induced by oleic acid (OA), a principal fatty acid in circulating triglyceride of blood stream. Assays performed include a tetrazole (MTT) assay, a wound healing assay and a Western blots. VSMC proliferations were enhanced by OA in a dose-dependent manner at concentrations of $10{\sim}50\;{\mu}M$ and inhibited by DAS and DADS compared to non-treated control. OA-induced proliferations were also attenuated by DAS and DADS. OA-induced cell migrations were 2.5 times higher than non-treated control, and they were significantly attenuated by DAS (32% at $150\;{\mu}M$ and 50% at $200\;{\mu}M$) and DADS (40% at $150\;{\mu}M$ and 46% at $200\;{\mu}M$). OA-induced cell migration was also attenuated by PD98059 (ERK inhibitor), SB203580 (P38 inhibitor) and particularly by LY204002 (PI3K inhibitor) and SP600125 (JNK2 inhibitor). Additionally, Western blot assays showed that OA-induced JNK1/2-phosphorylation was down-regulated after treatment with DAS and DADS. In conclusion, the findings of our study support the idea that DAS and DADS may have a suppressive effect on the proliferation and migration of OA-induced VSMC and that this effect may be partly associated with PI3K and JNK2 pathways.

We examined the genetic diversity and abundance of picocyanobacteria using barcoded amplicon sequencing approaches and flow cytometry in the East Sea and the East China Sea to determine the distribution patterns of diversity during spring in seas adjacent to the Korean Peninsula. Synechococcus clades I and IV, which have been known as cold-adapted ecotypes, dominated at most stations. However, the relative abundances of the two dominant clades differed in their spatial patterns. Clade I was exclusively dominant in the shelf area of the East China Sea and the north East Sea. However, the dominant genotypes belonging to clade I had different spatial distributions in the two areas and responded oppositely to seawater temperature. The dominance of distinct genotypes under the different ecological conditions suggests the presence of ecologically different ecotypes within the clade. Abundances of clade IV were greater than those of clade I at most stations in the southwest East Sea, showing an apparently different pattern from that of the other areas. A warm-water adapted clade II was observed at significant levels only at stations located in the eastern East China Sea affected by a branch of the warm Kuroshio Current. These results suggest that the physicochemical properties of influencing water masses play an important role in determining the distribution of Synechococcus genotypes.

The purpose of this study was to analyze the patterns and the interrelationships for meeting guidelines of three health behaviors including physical activity(PA), sedentary behavior(SB), and dietary behavior(DB) for Korean adolescents using 2007 KYRBS(Korea Youth Risk Behavior Survey) data. A cross-sectional design was used to assess 73392 middle-high school students. PA(moderate physical activity${\geqq}$5times/week, or vigorous ${\geqq}$3times/week), SB(watching TV, computer, DVD, video, etc. < 3 hr/day), and DB(servings of fruits ${\geqq}$1 times/day, or vegetables ${\geqq}$ 3 times/day) were categorized into two levels (meeting guidelines or not). Chi-squared tests were conducted to compare the prevalence of students not meeting these three health behaviors between boys and girls, and logistic linear regression was used to determine the interrelationships of three health behaviors. Students meeting guidelines for PA, SB, and DB were 31.0%(boys 42.6%, girls 18.0%), 74.7%(boys 75.4%, girls 74.0%), and 38.5%(boys 38.6%, girls 38.4%), respectively. In addition, there were significant differences between both genders for PA and SB (PA; $x^2(1)$=35175.11, p<.0001, SB; $x^2(1)$=19.44, p<.0001). Only 10.9% of students met all three guidelines and 12.4% did not meet all three. Pattern that simultaneously did not meet PA and DB were high in both boys(27.1%) and girls(37.2%). Students who did not meet DB were at greater risk of not meeting PA(Boys; OR 1.49, 95% CI 1.43 to 1.55, Girls; OR 1.42, 95% CI 1.34 to 1.50), and not meeting SB(Boys; OR 1.41, 95% CI 1.34 to 1.48, Girls; OR 1.36, 95% CI 1.29 to 1.43) compared with students who met DB. The findings of this study supported further evidence for the need of a multiple behavior approach considering gender and interrelationships among three behaviors.

This study was conducted to investigate the effect of shoot training method on the plant growth and fruit quality and yield of 'Sinsakigake-2' and 'Shishito' peppers (Capsicum annuum L.) grown in the glasshouse. Plants were either left untrained as control or trained at the third node leaving two or four shoots per plant. The untrained control plants had no pruning and therefore had all the lateral branches. The growth was enhanced in plants with two trained shoots in both cultivars. Fruit length and width, fruit weight, and pericarp thickness were not affected by the number of shoots trained. However, the percent marketable fruits was the highest in plants with two trained shoots, and the number of marketable fruits per plant was the highest in plants with four trained shoots. Marketable yield in plants with four trained shoots increased 15% in 'Sinsakigake-2' and 5% in 'Shishito' as compared to that of the control. Results of this study showed that yield and quality of pepper fruits were promoted by training with four shoots and the effect was more pronounced in 'Sinsakigake-2' than 'Shishito' pepper.

Financial technology (FinTech) is an emerging financial service sector include innovations in financial literacy and investment, retail banking, education, and crypto-currencies like bitcoin. One of the crucial branch of financial technology-third-party payment (TPP) is undergoing rapid growth, with online/mobile systems replacing offline financial systems. System quality and user attitudes are key perceptions driving third-party payment usage, the importance of these perceptions, however, may be different with countries as users' thinking varies from country to country. Thus, the purpose of this study is to elaborate how factors differ from China to Korea by drawing on the unified theory of acceptance and use of technology (UTAUT2). Additionally, this study also aims to propose a multi-attribute evaluation of the third-party online payment system based on analytic hierarchy process (AHP), fuzzy sets and technique for order performance by similarity to ideal solution (TOPSIS), to examine the relative importance of the perceptions influencing new technology adoption intention. The results showed that the price value has the most significant influence on Chinese perceptions, while the perceived credibility has the most significant effect on Korean perceptions. Sub-criteria also performs different results to Chinese and Korean third-party online payment system.

This study was Dental health determinants of elderly people. For this purpose, a questionnaire was done for 396 elderly people of 60 or more years old who have visited Seogwipo city public health center(branch) in Jejudo from May 27th to June 5th 2013 after they heard the intention of that investigation. Result of the most answers were 'normal' for the question asking the subjective status of teeth health of whom having more than 20 natural teeth as 73.3%; the most answers of whom with less than 19 natural teeth were 'bad' as 41.4%, which showed difference(p<0.05). The factors influencing the subjective teeth health were 4.3times higher in cases of women than men. The higher educational(high school or more)had they, the more monthly average income(2 million won or more) did they have, the higher was their subjective teeth health status(p<0.01). It is more important than anything that they reserve more than 20 natural teeth until they get old to keep and improve their oral and body health. In addition to that, the oral health project or oral health program to perform country-wide programs for free, consistent and systematic oral health examination and education should be planned.
