On-arrival duty free will prevent Korean outbound passengers from keeping the duty free items they purchased at the departure during their travel. Most Korean tourists have requested the airport authority to install on-arrival duty free since the grand-opening of Incheon int'l airport. Considering the fierce hub airport competition in the North East Asian region, the Korean government's decision to install on-arrival duty free is regarded as a well-timed intervention. The purpose of the research was to analyze sales correlation based on a comparison of sales of both departure and on-arrival duty free and to propose an administrative implication. Compared to business conglomerates running departure duty free, on-arrival duty free operators, who are small or medium companies, have weakness in product composition, marketing, and merchandising capabilities. According to the analysis, outbound passengers, who purchased fashion accessories and leather products at the departure duty free, tended to purchase cosmetics/perfume or liquor on the arrival duty free. Such complementary purchasing behavior of passengers showed there is barely a negative correlation between departure and on-arrival duty free.

In Korea, there are a lot of regulation on gambling industry. Among them, the most unique regulation is the CAP system. The purpose of CAP system is to minimize the social side effects of gambling industry. For that, National Gambling Control Commission controls the maximum number of business premises of gambling companies. The CAP system is a means of preventing excessive expansion of the gambling industry. The CAP system has lasted since 2009. This study investigate how the CAP system influence the structure of gambling industry. In result, after the CAP system carried out, the growth rates of gambling industry are similar to those of national GDP. And before the CAP system, the HHI index and CR index were decreasing trend. However, after the CAP system, the HHI index and CR index were not decreasing. That means the structure of gambling industry has been stable and settled. And there were few variation among the gambling companies in sales. In conclution, the CAP system influenced the gambling industry to be stable. There were few competition among the gambling companies in Korea. And the structure of gambling industry has been settled.

We tried new analysis including social network analysis(SNA) on the transaction network centered on electronic companies using more than 50 thousand company transaction data obtained from Korean enterprise data (KED) for the year of 2015. We found 97 clusters having more than 10 firms and remarkable 13 clusters having more than 90% sales of the electronic industry in Korea. Clusters are the groups of companies having most of their transactions in the clusters they belong to. We found 5 clusters have 83% of sales in the electronic industry. Most of clusters have main single firms having most of the sales in each clusters except a few clusters. However, we found a few firms to have high rear production linkage effect and found the firms with high linkage effect specially for the small and medium size enterprise (SME). The companies with high production linkage (specially on SMEs) should be managed in terms of (SME) growth policy. The last firm group consisting of the small clusters with less than 10 firms has high employment coefficients. The clusters or company having high production linkage effect on this last firm group should be noted in the terms of employment policy. We also note that there exist the firms with the high value of betweenness coefficients meaning high potential of technology development. They should be managed carefully in terms of technology development policy.

This paper investigates the performance of technology innovation activities performed by firms in 16 major regions in Korea using 2002-2010 survey data by STEPI. The theoretical and empirical analysis is carried out via the 2 models which are the simple R&D - total revenue model and Cobb-Douglas model based on the simple model adding labor variable. The main results shows that for simple model, the R&D elasticity for total revenue is 0.42 for all areas and Ul-San shows the highest elasticity level, 0.66 and Bu-San the lowest level, 0.2. In case of Cobb Douglas model the R&D elasticities are not statistically significant for many regions. To overcome the low statistical significance, we grouped the 15 regions for 3 wider regions using ANOVA based on the R&D intensity for the homogeneity of R&D activities. By grouping, each region has more observations to analyze and the results from the empirical analysis shows higher statistical significance level and data explanation capability. In this case, Group 3 which shows larger firm size and slightly higher export share shows the highest level of R&D elasticity, 0.088 and Group 1 which has the smallest firm size and the lowest revenue growth rate shows the lowest level, 0.31. For the labor elasticity, Group 1 shows the higest level, 1.16 and Group2 the lowest level, 1.096. These results show that the regions which have many middle and small firms reveal low R&D-revenue elasticity and high labor-revenue elasticity.

This paper adopts a resource-based approach to analyze why some universities have a greater number of faculty startups, and how this impacts on performance, in terms of indictors such as the number of employees and revenue sales. More specifically, we propose 9 hypotheses which link institutional resources to faculty startups and their performance, and compare 5 different groups of university resources for cross-college variation, using data from 134 South Korean four-year universities from 2017 to 2020. We find that the institutional factors impacting on performance of faculty startups differ from other categories of startups. The results show that it is important for universities to provide a more favorable environment, incorporating more flexible personnel policies and accompanying startup support infrastructure, for faculty startups, whilest it is more effective to have more financial resources and intellectual property for other categories of startups. Our findings also indicate that university technology-holding company and technology transfer programs are crucial to increase the number of faculty startups and their performance. Our analysis results have implications for both university and government policy-makers, endeavoring to facilitate higher particaption of professors in startup formation and ultimate commercialization of associated teachnologies.

ESCO는 매우 특수한 제도이므로 팩토링 및 회계처리의 근거자료를 확보해 놓을 필요가 있다. 특히 관공서와 ESCO사업을 실시할 경우, 계약서에 에너지절약시설의 소유권 이전을 대금상환 완료시까지 회사에 유보하는 것을 명시하여 관공서 ESCO사업은 ''장기할부거래''로, 일반 ESCO사업은 ''일반원칙거래''로 개념을 정리, 회계에 적용해야 한다. 또한 ESCO사업을 ''용역거래''가 아닌 ''건설공사''로 인식하고 있는 세무공무원이 있다는 점을 감안, 회사매출액을 ''용역매출'' 또는 ''엔지니어링매출''로 표현하여 건설공사로 볼 소지를 차단해야 한다.

소매점에서 판매를 최대화하여 이익을 극대화하기 위해서는 투자비용을 최소화하고 재고를 최소로 유지하며, 결품을 최소화해서 매출을 보호해야 한다. 수요의 동향이 다양화 됨으로써 예측이 점점 어려워지고, 재고를 최소화하고, 빠른 납기를 충족시키고, 판매 기회의 손실을 최소화 하기란 점점 어려워지고 있다. 또한 매출의 보호와 재고의 축소는 서로 상반되는 내용을 담고 있다. 전통 Industrial Engineering(IE)에서 경제적 주문량(EOQ)을 결정하여 재고 회전율을 높이고 발주 비용과 재고 비용을 최소화하는 연구는 많이 다루어져 왔다. 본 논문에서는 TOC의 쓰루풋 증대의 관점에서 최적의 재고 보충 관리 방안을 제시하고자 한다.
