  • There is an increasing need to foster new industries at the local level. This study aims to analyze the spatial patterns of new industries in Korea from 2007-2017 and to figure out its determinants of agglomeration in 2017. Through this study, it is found that new industries are unevenly distributed around Seoul Metropolitan Area(SMA). The regional disparity between SMA and non-SMA is prominent. Furthermore, new industries represent a strong spatial positive autocorrelation, showing a strong concentration on a few regions in Korea. This study explores the determinants on agglomeration of new industries with spatial statistical model. From the results of spatial error model, it is indicated that the number of graduate students, the ratio of technology based start-ups, and the number of elementary, middle, and high schools have a significant effect on new industries. In addition, the specialization and the diversity of industrial structure on knowledge-based manufacturing industries and knowledge-based service industries have been statistically significant. This study provides implications that non-SMA needs policies with respect to attracting talented people, developing human resources, and improving regional environment in order to improve regional competitiveness in promoting new industries.

  • This study aimed to develop the multi-span plastic greenhouse which is suitable for tomato cultivation and is safe against climatic disasters such as typhoon or heavy snow. The width and heights of eaves and ridge of newly developed tomato greenhouse are 7, 4.5 and 6.5 m, respectively. The width is the same but the eaves and ridge heights are 1.8 and 2 m higher than conventional 1-2 W greenhouses, respectively. Cross beam has been designed as a truss structure so it can sustain loads of tomato and equipment. Tomato greenhouse has been designed according to climatic disaster preventing design standard maintaining the high height. In other words, the material dimensions and interval of materials including column and rafter have been set to stand against $40m{\cdot}s^{-1}$ of wind and 40 cm of snow. Tomato greenhouse has been equipped with rack-pinion type roof vents which have been used in glass greenhouse in order to prevent excessive rise in air temperature. This vent type is different from that of 1-2 W type greenhouse which is made by rolling up and down the vinyl at upper part of column. Roof vents are installed at ridge, and thus external air inflow and natural ventilation are maximized. As the height increases, heating cost increase as well and, therefore, tomato greenhouse has been equipped with multi-layered thermal curtain, of which thermo-keeping is excellent, to prevent heat from escaping.

  • The primary goal of this research is to link two currently disconnected literature; the history of urban redevelopment and the one of urban parks and open spaces in the United States (US). Through this exercise, this study attempts to reveal examples of urban parks and open spaces that have yielded economic effects, and emphasize their possibility as a measure of urban redevelopment. Five phases are presented, starting with two Pre-World War II urbanization periods, and three subsequent periods of Post-World War II urban redevelopment (1940s~1960s, late 1960s~1970s, 1980s~present). While urban parks in the 19th century urbanization period held a preeminent place in urban design, policy and economy, ensuing depression and World War II diminished their role as a channel to ease unemployment. In the first phase of urban redevelopment, the economic motive to build open space was to boost the appeal of specific locales in order to draw people and businesses back to a neglected city. In the second phase, public effort to create and maintain urban parks and open spaces declined due to the budget austerity, instead, community open spaces flourished through the voluntary actions and helped neighborhoods to regain desirability. In the third phase, the aspirations and functions of such projects resemble their forerunners of the first phase, but their targets extended to global businesses and elites.

  • The purpose of this study was to examine the effectiveness of family-friendly management in 501 family-friendly certified firms and to analyze organizational and social outcomes outlined by the firms. In addition, this study aimed to discover ways to promote family-friendly management by investigating the effects of ongoing support to certified firms, including family-friendly consulting and workplace training. The results showed that certified firms administer family-friendly workplace policies at a satisfactory level, while their management of policy indices and outcomes were not effective. The finding suggests that family-friendly management indices need to be aligned with firms' substantial outcomes. An improved organizational image and trust were major organizational outcomes of family-friendly management, and an enhanced CEO perception and a culture centered on gender-equality were significant social outcomes. These outcomes need to be promoted to attract organizations to engage in family-friendly management. The finding further implies the important roles of organizations in cultivating family-friendly environments in society. Finally, the certified firms with ongoing consulting and training support exhibited higher levels of family-friendly management and organizational and social outcomes. This study sheds light on the importance of long-term, systematic efforts by organizations in fostering family-friendly management and achieving organizational and social outcomes.

  • In this study, the fatty acid (FA) composition of commercial sesame oils (n = 62) was investigated using gas chromatography with flame ionization detector (GC-FID). Multivariate statistical techniques, including principal component analysis (PCA) and linear discriminant analysis (LDA), were applied to the chromatographic data of the FAs to discriminate the geographical origin of sesame oils. A statistically significant difference was observed in the content of C16:0, C18:0, C18:1, and C18:2 between domestic and imported sesame oils. A satisfactory recovery rate of 82.8-100.2 % was achieved for C16:0, C18:0, C18:1, C18:2, and C18:3. The correlation of C16:0, C18:1, and C18:2 in domestic sesame oils showed opposite trends compared to imported oils. The PCA plot demonstrated that sesame oils were clustered in distinct groups according to their origin. LDA was used to predict sesame oil samples in one of the two groups. C16:0 (Wilks λ = 0.361) and C18:1 (Wilks λ = 0.637) demonstrated the highest discriminant power for classifying the origin of the samples. The correct prediction rates were 88.9 % and 100 % for the domestic and imported samples, respectively. Further, 60 of the 62 sesame oil samples (96.8 %) were correctly classified, indicating that this approach can be used as a valuable tool to predict and classify the geographical origin of sesame oils.

The Meaning and the Legislative Suggestion about Data Manipulation of Pharmaceutical Companies in the Aspect of the Medicine Approval System (의약품 품목허가 제도에서 제약기업 자료조작의 의미와 입법 개선 방안-대법원 2008. 11. 13. 선고 2008두8628 판결을 중심으로-)

  • The National Assembly of the Republic of Korea recently enacted laws to fortify sanctions about data manipulation of pharmaceutical companies. The medicine approval system is the result of legislative efforts to prevent accidents that caused damages to patients' life and health. The medicine approval system is based on the trust that the data submitted by pharmaceutical companies is not manipulated. The Supreme Court of Korea clarified that strict standard shoud be required to secure the medicine safety in Supreme Court Decision 2008Du8628 decided November 13, 2008. We agree. This paper suggest legislation to weaken the economic incentives for pharmaceutical companies to choose data manipulation by minimizing the expected profit. In addition to revoking the marketing authorization of the medicine, the 'unfair' profits the pharmaceutical company has earned must be recovered. In addition, in order to increase the possibility to discover data manipulation, it is necessary to strengthen the review capacity and to activate the whistle-blowing.

  • This study examines the concentration in terms of supply and consumption in the Korean movie market, focusing on screen size, nationality, and the box office. For analysis, it selects the top 100 movies in the box office each year for 15 years from 2005 to 2019. According to the result, the number of screens increased steadily every year, and the screen concentration became very high. For the top 100 movies, it increased from 12% to 30% of the total screen. It became higher in the case of the top 10 movies. As the number of screens increased, multiplex assigned more screens to one movie. Multiplex's screen allocation continued to increase, with one movie taking up more 60% of the total screen. This became more serious after 2011 and 2012. Market share of the top 100 movies accounted for about 95% of the total box office performance, even though the number of released movies is about 3,000. Whether multiplex preferred Hollywood movies or not, its screen assignment was found to favor Hollywood movies over Korean ones. In the case of film nationality, both Korean and Hollywood movies accounted for 90.7%. Two countries had a market share of 96.6%. There was no single side except Korea and the United States in the top 10. The increase in the number of screens deepened the concentration in screen allocation. The concentration in the screen allocation led to the concentration of consumption. The Korean film market is the case where the increase of movie screens did not create a diversity of supply and consumption. It also did not affect the diversity of film nationality. This research reveals that supplied concentration and consumed concentration are positively correlated, and that the former is a little lower than the latter.

  • Space exploration is an area where international cooperation takes place more actively than any other space activities such as Earth observation, communication and navigation. This is because a country cannot afford a huge budget to have full infrastructure for deep space exploration, such as a heavy launch vehicle, communication and energy infrastructure, and human habitats, and has learned that it is not sustainable. Korea expressed its willingness to join humanity's epic exploration journey by signing the Artemis Accords in 2021 and launching Danuri lunar orbiter in 2022. The beginning of space exploration means that Korea's space activities have expanded beyond the stage of focusing only on technology development to set norms necessary to accompany other countries and cooperate diplomatically to solve exposed problems. This paper analyzed European space policy and space exploration, which are most actively participating in the Artemis Program and exerting diplomatic power in the space field, from the perspective of science and technology diplomacy. The suggestions for Korea's space exploration strategy from the perspective of science and technology diplomacy were drawn by examining the international cooperation strategies in Europe's space activities ranging from space policy, space strategy, and space exploration program to project units.

  • The emissions trading system stands as a pivotal climate policy in Korea, incentivizing abatement equivalent to 87% of total emissions (as of 2021). As the system likely has a far-reaching impact, it is crucial to understand how the real economic activity, energy sector, as well as environment would be influenced by its implementation. Employing a macroeconometric model, this paper is the first study analyzing the effects of the Korean emissions trading policy. It interconnects the Korean Standard Industrial Classification (Economy), Energy Balance (Energy), and National Inventory Report (Environment), enhancing its real-world explanatory power. We find that a 50% increase in emission permit price over four years results in a decrease in greenhouse gas emissions (-0.043%) and downward shifts in key macroeconomic variables, including real GDP (-0.058%), private consumption (-0.003%), and investment (-0.301%). The price increase in emission permit is deemed crucial for achieving greenhouse gas reduction targets. To mitigate transition risk associated with price shocks, revenue recycling using auction could ensure the sustainability of the economy. This study confirms the comparative advantage of expanded current transfers expenditure over corporate tax reduction, particularly from an economic growth perspective.

  • This study was conducted to analyze the anti-oxidant activity of green juice containing barley sprouts. The specimens used in the experiments were supplied byCSJ company located in Jincheon-gun, Chungbuk province. Polyphenol and flavonoid was detected in Huttuynia cordata Thunb fermentation sprout juiceat $1.075{\pm}0.174mg/mL$ and $2.736{\pm}0.187\;quercetin\;mg/mL$, in organic dandelion at $1.048{\pm}0.173mg/mL$ and $2.685{\pm}0.245\;quercetin\;mg/mL$, kan andRakat $1.013{\pm}0.083mg/mL$ and $3.624{\pm}0.237\;quercetin\;mg/mL$, broccoli blending juice at $1.494{\pm}0.255mg/mL$ and $3.826{\pm}0.286\;quercetin\;mg/mL$, and barley sprouts at $1.043{\pm}0.220mg/mL$ and $1.990{\pm}0.223\;quercetin\;mg/mL$, respectively.Antioxidant activity testing revealed the electron donating ability of Huttuynia cordata Thunb fermentation sprout juice for DPPH was 81.97%. Moreover, the free radical scavenging ability measured by ABTS assay showed that the activity was increased in the order of broccoli blending juice, Huttuynia cordata Thunb fermentation sprout juice, organic dandelion, 'kan andRak', barley sprout, and thatthe effects were similar to those of ascorbic acid at $100{\mu}g/mL$. Statistical processing is using SPSS 24, analysis of distributed layout and Duncan's multiple range (p<0.05). Therefore, the use of functional assistance material of products in the future indicates that it is worth a healthy functional drink.
