In order to maintain customer voltages within allowable limit($220{\pm}13V$) as much as possible, tap operation strategy of SVR(Step Voltage Regulator) installed in distribution system is very important, considering the scheduled delay time(30 sec) of SVR. However, the compensation of BESS(Battery Energy Storage System) during the delay time of SVR is being required because the customer voltages in distribution system interconnected with PV(Photovoltaic) system have a difficultly to be kept within allowable limit. Therefore, this paper presents the optimal voltage stabilization method in distribution system by using coordination operation algorithm between BESS and SVR. It is confirmed that customer voltage in distribution system can be maintained within allowable limit($220{\pm}13V$).

Purpose - Considering the importance of education as the base for countries' development, the results of various studies show that accounting education is not reconciled to business environment changes with huge defects in methods of education and knowledge transition. Research design, data, and methodology - By reviewing current research and considering the effect of 12 factors, the study traces and detects why accounting education is far from the business environment from viewpoints of academic and practitioner bodies. After testing for validity and reliability, 225 questionnaires were administrated among representatives of three groups. Results - Respondents were not satisfied with lack of specification of various scientific areas of accounting, that less attention is paid to accounting software education, and about the rarity of workshops for performing accounting skills and discordance between accounting education and standard rules. Conclusion - These findings agreed with Albrecht and Sack (2001) who stated that the current style of accounting education is very cluttered and incomplete and needs major adjustments: subjects of accounting education must be based on the grounds of work needs not on willing academics.

As intellectual property has become an important competitive element in the industry, government-led patent education is rapidly expanding. It is important to look at whether each patent education course is organically linked to each other under a life-long patent education system from elementary school to college. This study focused on the link between high school education and college education to analyze statistically how invention activities in high school affect patent education achievement at college. Statistical analysis of a survey of students taking a basic course of intellectual property revealed no statistically significant correlation between invention experience in high school and college students' patent class total score, contrary to popular perception. These results are believed to be due to the distribution of data on the number of invention contest participations or the number of invention class participations, which does not form a normal distribution and has a relatively large skewness. Rather, the attendance to the patent class showed a relatively distinct positive linear correlation with the patent class total score, indicating that the student's attitude in class was important for the patent education achievement.

This study examines the mackerel distribution systems in Norway which has a leading mackerel industry, and has the purpose of analyzing the effects of structural improvements for the development of Korea's mackerel industry. The landing and distribution status of Korea and Norway's mackerel industry was compared, and the effects of structural improvements was analyzed under the assumption that a number of factors would be improved after an analysis of competitiveness. Special features of the landing and distribution systems of mackerel in Norway are Reduction of transportation costs and transportation time through E-auctions, fish Pumps, freshness management using state-of-the-art equipment and technology such as sea water cooling systems, direct landing at processing factories and Automation through fully automated sorting & packaging systems. The distribution competitiveness of Korea and Norway's mackerel industry was compared through the qualitative review of landing time and the length of distribution channel, distribution costs due to differences in trading method, quality and hygiene management and merchandising. For Korea's mackerel industry to have international competitiveness, they must have efficiency throughout the phases of landing, processing and distribution systems as observed in case of Norway.

Purpose: The purpose of this study is to investigate the distribution of ancient Korean books around the world, and to study the process and impact of Myongsimbogam's distribution to East Asia and Europe. Research design, data and methodology: This study conducted literature research as its research method. The scope of research covers Korea, China, Japan, Vietnam, Spain, Germany and Russia. Results: Ancient Korean books were distributed through the Kwanpan and Banggakbon, and leaked overseas in historical circumstances. Myongsimbogam was distributed to Korea, China, Japan, Vietnam, Spain, France, Germany, and Russia. Myongsimbogam was the first ancient book to be translated into Western languages. Conclusions: The distribution of Myongsimbogam promoted the exchange of spiritual civilizations in the East and West, and became the basis for maintaining an individual philosophy, as well as social order. Therefore, the distribution of Myongsimbogam needs to be further expanded. For this, it is necessary to translate Myongsimbogam into English and popularize it through e-books, audio books and various lectures. While previous studies on Myongsimbogam have mainly focused on personality and moral education, this study is significant in that it examines the distribution and dissemination process of Myongsimbogam, its influence and significance.

Objectives: This study aimed to assess the improvement of teachers' sanitation performance and food distribution environment at Centers for children's food service management after a sanitation education program. Methods: The subjects were 119 teachers working at child care centers registered in the Daejeon Center for Children's Foodservice Management in Dongu and Jung-gu, Daejeon. The sanitation education was provided three times from March to August in 2014, and the survey questionnaires were distributed before and after the education. The sanitation status of food service environment of the centers was examined by ATP(adenosine-5'-triphosphate) bioluminescence. Results: After the sanitation education, the teachers showed higher levels of sanitation knowledge. Also, sanitation performance and recognition level of the importance of it significantly improved after the education program. The mean variation scores of importance and performance after the education were 0.14 and 0.23. According to the Importance-Performance Analysis (IPA) results of 26 sanitation attributes about the food service environment, the selection attributes with relatively low performance and importance were mostly distributed in the children's and distributer's personal hygiene management area. However, all attributes except using a personal water bottle and cup were moved to high performance and importance level. Also, the ATP examination results showed that the sanitation status of the food service environment was improved after the education program. Conclusions: The sanitation education program was effective in improving the recognition of the importance of sanitation and its performance with regard to food service management.

Purpose: Research and development of human capital in countries bring sustainable development to the nations. Especially for developing countries, the attraction of foreign direct investment not only brings economic growth to the country but also contributes to improving human capital. This study aims to assess the impact of foreign direct investment on human capital in ASEAN countries. Research design, data and methodology: With data collected from ASEAN countries from 1990 to 2019, panel data analysis is performed with revised model types (the Pooled OLS, Fixed effect model, Random effect model and regression with Driscoll-Kraay standard errors). Result: The results of the regression analysis show that FDI has a positive impact on human capital. At the same time, the study also found that public investment in education also positively affects human capital; the life expectancy factor does not affect human capital. Conclusions: With this research result, the authors also proposed a number of solutions to improve human capital by attracting FDI and improving the efficiency of investment for the education of ASEAN countries. Besides, public expenditure on education also plays an important role in raising human capital. Therefore, investment in education should be promoted further in the future.
