The aims of this study were to investigate (1) the status of food materials purchased by group-buying companies and (2) the satisfaction with food materials and service quality of group-buying companies in foodservice at child-care centers. In November 2013, child-care centers which were participated in a group-buying program in Gwanak-gu, Seoul were requested to complete self-reported questionnaires. One hundred and eight respondents (76.9% of directors, 23.1% of non-directors) completed questionnaires, including purchase frequency of food materials, degree of satisfaction with 'food materials' and 'operating system and service' of group-buying companies. About 60% of child-care centers purchased food materials from major companies. Respondents' overall satisfaction with 'food materials' and 'operating system and service' were '3.55' and '3.72' out of 5 points, respectively. For overall satisfaction with food materials, there were significant differences between 'public (3.79)' and 'private, home-based (3.31)' child-care centers (p=0.023). The results of multi-regression analysis showed that quality (${\beta}$=0.271, p=0.013) and price appropriateness (${\beta}$=0.284, p=0.002) were associated with overall satisfaction with food materials purchased by group-buying companies. The factors such as delivery accuracy about items(${\beta}$=-0.201, p=0.042), hygiene of delivery process (${\beta}$=-0.207, p=0.025) and communication with companies (${\beta}$=-0.317, p=0.003) were significantly associated with overall satisfaction with operating system and service provided by group-buying companies. The results of this study could be utilized for group-buying companies and the government to develop guidelines and policies on food material buying in foodservice at child-care centers.

This paper addresses an assessment model for selecting PL(Private Level) product companies. The proposed model extracts the weights of evaluation elements based on AHP(Analytic Hierarchy Process). These evaluation elements are from real-world instances in a domestic hyper market. Especially, the model points at food products which constitute a large portion of entire profits in the market. In this model, we first classify the 54 evaluation elements into 4 layers and secondly carry out a survey with relevant specialists based on them. We also estimate the weights of evaluation elements according to pairwise comparisons from the survey, and propose them as a quantitative alternative which can be applied in real-world problems. Finally, the pilot-study is conducted to compare the proposed model with the existing simple summation method. From this study, HACCP system assessment and Review(0.279281), Transportation(0.117706) and Fundamental law observance(0.066392) are presented as the key evaluation elements for selecting PL product companies. The proposed model facilitates the company selection among those candidate companies which is not easy to determine the superiority by reflecting the importance of evaluation elements.

The purpose of this study is to present meaningful information and policy implications concerning the determinants of royalties of technology transfer to stakeholder. To identify key determinants of royalties in technology transfer, this study conducted AHP survey analysis (Survey period: 01/09~31/10, 2016) of 96 government-funded research centers and 85 companies which were participants of the R&D project "Next Generation BioGreen21" of R.D.A in the "N" center from 2011 to 2015. Research results show that both parties acknowledge 'Technical considerations for determining the profitability of the technologies' and 'The interest and willingness of the management group' as critical factors for the determinants of royalties. The difference of each party is that private companies acknowledge 'Available budget plan' as a critical factor while the government-funded research centers value 'Market competitiveness'. These findings suggest four main policy implications which are the investigation of technological demands reflecting specific needs of industrial sites, the diversification of royalty payments for private companies, the differentiated research evaluation system for the purpose of technology transfer and the planning of public R&D project reflecting research time span of private companies.

Unlike the semi-public system of city buses, Seoul's townbus are operated on a private operating system, which is poor condition to the changes in the environment. Sales decreased due to a decrease in the number of passengers due to COVID-19 and a demand for conversion due to the advent of competitive transportation methods, and the financial support of Seoul Metropolitan Government is continuously increasing. In this study, to analyze the characteristics of townbus operated by a private operating system, the townbus sales and surplus companies were analyzed by what factors were affected. For the analysis data, townbus financial statements of Seoul in 2018 were used, and townbus sales and surplus companies were applied as dependent variables, and townbus operation system, satisfaction survey, humanities and social variables, and subway and public bicycle characteristics were applied as independent variables. As a result of the analysis, the sales is affected by operating hours per vehicle, in-vehicle safety, the number of households, the number of elderly people, and public bicycle variables, and surplus companies are affected by in-vehicle safety, reliability, and public bicycle variables. In particular, public bicycles, a competitive means of transportation, had an impact on industry sales, and the townbus business environment is expected to become more difficult as time goes by. The industry is seeking self-rescue measures, and Seoul is required to strengthen financial support so that townbus can operate stably.

This study aims to examine the causal relationships between sales and employment for public technology-based startups. Although there is a limit to statistical generalization due to the poor understanding of the actual conditions of public technology start-up companies, these companies were analyzed by classifying them into high-growth companise, potential growth companies, and other companies. In order to understand the causal relationship, and to estimate the time required to be effective, panel vector autoregression was applied. As a result, the performance creation mechanism was identified as government supoort and private investment was mutually causal with employment, sales did not cause employment, and employment caused sales. In other words, it was found that employment plays an mediator role in public technology based startups' performance mechanism. In addition, private investment had the effect of improving employment and sales in the short time than governments support, and showed that firms with high employment can attract government support and private investment. This study are academically meaningful in that they empirically revealed the process of performance creation, whereas previous studies had only shown whether there was an effect on performance. It also has a policy contribution by suggesting the need for effective policy promotion by considering the 'employment' factor, such as human resource support, as more important.

Emerging trends regarding USFK(United States Forces, Korea)'s EC(Engineering/Construction) market include: (1) introduction of MATOC(Multiple Award Task Order Contract); (2) increase of DB(Design-Build) contract; and (3) encroachment of large US-origin private EC firms upon Korea. This study analyzes the change of USFK's EC market with focus on the change of construction management actors for USFK's EC projects. Specifically, USFK's EC projects have been managed by FED(Far East District). Recently, however, the large US private EC companies substitute the role previously taken by FED. This phenomenon is accelerated by the business chances in Korea due to LPP(Land Partnership Plan) and intentions of US Government to save military construction costs by means of utilizing US private EC companies. The large US EC firms entering into Korea are business opportunities as well as challenges to Korean EC firms, which are contracting USFK's EC projects. This study concludes that, through teaming joint venture with the large US EC firms, the market changes can be opportunities to acquire foreign market information and learn advanced construction management skill from them.

This paper analyzes Japan's consignment management of the Chosun Railway to the South Manchuria Railway. While Chosun Railway was entrusted, its management style differed significantly from that of Japan's direct management. After eight years of trust management, the direct management of Chosun Railway was returned to Japan. This of beyond border trust management is very rare. In addition, the management of Chosun Railway by South Manchuria Railway, which had an operation style similar to that of a private company, led to changes in Chosun Railway. This research analyzes the four key traits of South Manchuria Railway's consigned management. The first key trait is the initial Korean infrastructure and operation separation model. The second key trait is the international transportation and administration segregation. The third key trait is that it expanded the railway related businesses and led to the establishment of private railway companies. The fourth key trait is that the continental linked transportation was activated. Through analyses, it would be to create a comparative study of the resulting East Asian countries' operations. Furthermore, this research will in investigating the nature of Chosun Railway.
