Sports has become one way to improve our own health and to enjoy life by changing the lifestyle of modern-day people. Sports athletes not only give pleasure to the public, but also play a role in elevating a nation's reputation through sports. Tennis is popular with the public, and women players receive tennis wear from various sports companies to promote the designs to the public. This study considers the design-related characteristics of women's tennis wear through content analysis of design elements from the tennis wear in four major tournaments over the most recent five years. This is important in order to provide basic data on design directions for tennis wear in the future. The results of this study are as follows. First, the silhouette plays a role in enhancing activity by considering the physical movement of tennis players who are very active. Second, color emphasizes the rules and clarity of traditional tennis tournaments, and reflects a diversified trend in tennis wear by considering smooth game play by players and combining popular colors in the year. Third, patterns and decorations on material are used as a means to emphasize the esthetics of tennis wear, and tape plays an auxiliary role in emphasizing the physical beauty of women or preventing physical movement causing injury. In addition, sponsor logos are generally located at the center of the chest of tennis wear tops by mixing letters and images. This can be interpreted as a part of the marketing strategy to enhance clarity of the sponsor's brand.

Forest fires have frequently occurred around the world, and the damages are increasing. In Korea, most forest fires are initiated by human activities, but climate factors such as temperature, humidity, and wind speed have a great impact on combustion environment of forest fires. In this study, therefore, based on statistics of forest fires in Gyeonggi-do over the past five years, meteorological and hydrological factors (i.e., temperature, humidity, wind speed, precipitation, and drought) were selected in order to quantitatively investigate causal relationships with forest fire. We applied a partial least squares structural equation model (PLS-SEM), which is suitable for analyzing causality and predicting latent variables. The overall results indicated that the measurement and structural models of the PLS-SEM were statistically significant for all evaluation criteria, and meteorological factors such as humidity, temperature, and wind speed affected by amount of -0.42, 0.23 and 0.15 of standardized path coefficient, respectively, on forest fires, whereas hydrological factor such as drought had an effect of 0.23 on forest fires. Therefore, as a practical method, the suggested model can be used for analyzing and evaluating influencing factors of forest fire and also for planning response and preparation of forest fire disasters.

In February 2020, Gyeonggi-do paid the world's first Data Dividend to local residents of Gyeonggi Province who produced data using local currency. Currently, Data Dividend is being paid to consumers who have produced data, but this paper studied the expansion of Data Dividend qualifications according to the contribution to creating added value. First, it raised the question of whether it is right for the recipient of Data Dividend to have only the consumers who produced the data. Second, by analyzing the four elements of data valuation criteria that influenced the creation of added value identified the objects that influence the creation of added value. The 4 factors were divided into productivity, effectiveness, concreteness, and usability, and the objects corresponding to each factor were analyzed. Accordingly, it was determined whether platform workers contributed to the creation of added value. In conclusion, it was confirmed that not only consumers, who were the first data producers, but also platform workers who contributed to the concreteness of data valuation to create added value can qualify for Data Dividend. Since this paper focuses on the necessity of data allocation centered on platform workers among the objects, the validity of objects that influence added value other than platform workers are excluded.

The purpose of this study is to present implications for revitalizing start-ups and contribute to enhancing the success rate of start-ups by clarifying factors and processes for converting workers with knowledge, experience and networks in related fields into entrepreneur. Based on the Shapero's Entrepreneurial Event Model, this study demonstrated whether the job insecurity and entrepreneurship of the workers were precipitating events of the entrepreneurial intention and whether the perceived desirability and feasibility of the entrepreneurial behaviour mediated between them. According to the results of the study, first, it was confirmed that job insecurity, innovativeness, and risk-taking of workers are factors that increase the entrepreneurial intention. Second, the indirect effect of perceived desirability between all components of job insecurity and entrepreneurial intentions was not significant, but all components of entrepreneurship appeared to improve entrepreneurial intention through perceived desirability. Third, it has been confirmed that job insecurity, innovativeness, and risk-taking strengthen the entrepreneurial intention through the perception of feasibility for entrepreneurial behavior. Through this study, it is confirmed that in order to convert workers into entrepreneur, it is necessary to strengthen entrepreneurship education and support for internal ventures for workers to increase their positive attitude and confidence in implementation. Therefore, it is expected to help solve job problems and revive the sluggish economy by contributing to boosting start-ups.

In modern society, interest in antioxidants is increasing as the stress caused by oxidants increases. However, the demand for synthetic antioxidants is decreasing because some studies have confirmed that they are harmful when consumed in large quantities; thus, studies on antioxidants derived from natural substances are actively being conducted to replace synthetic antioxidants. Blueberry, known as one of the world's top ten long-lived foods, is a plant of the Vaccinium (Ericaceae) family, and various pharmacological activities of blueberry including antioxidant activity have been studied. Vaccinium oldhamii (VO) is a deciduous broad-leaved shrub in the same genus as blueberries, and in this paper, we summarize the studies on the efficacy analysis of VO extracts and purified products. The content of phenolic compounds in VO fruits was proportional to antioxidant and anti-influenza activity such as the inhibition of NO production, and the total content of polyphenols and anthocyanin was higher than that in blueberries. VO fruit extracts showed anti-inflammatory activity and anti-cancer activity against human acute leukemia; in contrast, VO branch extracts showed anti-inflammatory activity, activity to inhibit osteoclast differentiation and bone resorption due to inflammatory response, and anti-cancer activity against several human cancer cell lines. Compared to blueberries, VO showed higher phenolic compound content, antioxidant activity, and various physiological activities. In addition, VO is considered to have sufficient value as an alternative crop to blueberries, such as it can be grown natively in Korea, with simple mass cultivation and no need to pay royalties for commercialization.

Recently, venture capital investment has been shrinking globally due to high interest rates and economic slowdown. Korea is no exception. Due to the downturn in the M&A and public markets, increasing economic uncertainty, and the aftermath of corporate bankruptcies, venture capitalists are facing many difficulties in raising funds. In the changed economic environment, the investment decision factors of venture capitalists have also changed. However, studies on VCs' investment decisions have focused on the general economic environment. This study examines how VCs' investment decision-making factors change during economic recessions and booms. To this end, we interviewed active investors who have experienced both economic recessions and booms to compare how VCs' investment decision factors change: 1) personal characteristics of founders, 2) experience of founders, 3) product/service, 4) market, 5) financial situation, 6) contract terms and 7) venture capital co-investment. The results showed that founder's personal characteristics, experience, and product/service were more important during the economic recession. Market is slightly more important during economic booms. The importance of financial situation and investment conditions increased sharply during the recession compared to the boom. Finally, venture capital co-investment did not differ significantly between recessions and booms. By understanding the investment decision-making factors of venture capitalists in the recent difficult venture investment environment, this study aims to help startups raise funds and survive in a difficult market.

The projection on the demand for seafarers is seen to continue to rise in consonance with the world's fleet increasing tonnage. It is also expected that recurring officer shortages is paramount when global markets bounce off from the economic downturn it experienced for the last few years. In BIMCO/ISF(The Baltic and International Maritime Conference/International Shipping Federation) report for 2010, a continuous effort to produce competent seafarers should be adapted and as much as possible, reduce the wastage in the industry to address the looming scenario. The Republic of Korea, an OECD member, is a powerhouse in shipbuilding industry and has also had continued to show also an expanding trend in its fleet. On the other hand, the Philippines is still acknowledged as the main source of manpower for ocean-trading vessels. In this paper, a statistical comparison of maritime graduates' career path between the two countries is presented. In conclusion, it is suggested that a mutual co-operation between the Republic of Korea and the Philippines can be established with focusing on international maritime education and training collaboration.

In spite of economic slump of global IT market, China is showing growth of $25\%$ per a year. After opening economy, the economic growth of the country haven't flagged. Moreover, According to the economic plan of the President HuJinTao who took office in 2002, IT field has been developing quickly. Even though such development is enough to show off the ability of China in the world, it is also a fart that there are many side effects. Among them, the imbalance of development between the east and the west is disturbing the general Chinese development. So the government is making efforts to reduce the gap as a solution, 'Go West campaign.' While progressing the policy, the related method which restricted domestic demand market advance from 2000 is abolished. We also established a bridgehead for lauching to the west of China at the same line with other developed countries. Based ell such reality, we understands the general present state and policy of Chinese IT industrial and the opportunity for abolishing the related method which restricted domestic market advance to also obtain from 2000, and for our country to also advance to the western area in China by the start onboard equal to other advanced nations. The direction to which we have to go by investigating the situation of a western area is investigated.

As the current level of birth rate of Korea has dramatically declined, it is obvious that pediatric dentistry will also be affected by this change. This study was performed for the purpose of understanding on the current fertility levels of Korea. The formal data on the number of live births(NLB), crude birth rate(CBR), and total fertility rate(TFR) published annually from the National Statistical Office of Korea from 1992 to 2000 were used as materials for this study. The TFR values from 1990 to 2002 of Korea were compared with those of some western countries with similar history of decreased birth and the CBR values of the metropolitan cities and the capital city Seoul in 2003 were compared domestically, yielding to results as follows. 1. Recent birth rate of Korea was decreased continuously. NLB was about 490,000 CBR was 10.2 and TFR was 1.19. 2. TFR of Korea in 2002 was 1.17, the lowest in the world. 3. There was a large difference in the NLB and CBR between local prefectures and towns of Seoul domestically. Additional population studies and medico-economical studies to exactly predict the demands of pediatric dentistry and proper supplies of manpower in the future was thought urgently required.
