Even though the efficient public transportation system has been issued in many areas, a few practical methodology of analysis and evaluation of the transit system has been developed since applying the practical methodology faces many difficulties as a feasible solution. For example, designing the public transit transfer system needs the feasible consensus of requirement and solution among the related people and institutes, which the system engineering concept should be involved. It is necessary and confident to analyze and evaluate the public transit transfer system in term of system engineering process.

Nowadays almost nations try to promote the competition of nation through the development of national science technology. Also Korea has been engaging in this race of through public research&development institute. But recently the commercialization of R&D products appears a poor result in the royalty of technology according weak technology transfer toward IT small and medium-sized enterprises. Even If we have been trying to find the problems and causes, as yet it is true that we don't solve clearly the problem, make a diagnosis about it. This paper analyzes the process of commercialization in public R&D research institute(ETRI: Electronics and Telecommunications Research Institute) through system thinking and researches an interrelationship among government agency, public R&D research institute, and enterprise. This one can find the fact that between research fund and R&D products, transfer technology and royalty, and enterprise's operating profit and active technology transfer like adding technology development is a positive feedback loop. This positive feedback loop in the commercialization of public R&D research institute carries out very important role in examining problems in R&D product's commercialization. Also this paper looks forward to being a guide in the commercialization of public R&D research institute.

The purpose of this study is to investigate whether depression and social support have a multiple mediating effect in affecting the life satisfaction of the elderly with public and private transfer income. To this end, the 7th panel data (2017) among the data of the Korean Retirement & Income Study (KReLS) was used for analysis, and the analysis was conducted using structural equation modeling (SEM). As a result of the analysis, first, it was analyzed that the higher the public transfer income of the elderly, the lower the level of depression, the higher the social support, and the higher the satisfaction of life. Second, the partial mediating effect of depression was verified in the influence of the elderly's public transfer income and private transfer income on life satisfaction. Third, the partial mediating effect of social support was verified in the influence of the elderly's public transfer income and private transfer income on life satisfaction. Fourth, it was verified that the multiple mediating effects of depression and social support were significant in the effect of the elderly's public and private transfer income on life satisfaction. Based on the results of this analysis, policy proposals were made, such as revitalizing the Community Care program to strengthen the social support network of the elderly.

Objective: This study was carried out for the purpose of identifying major substances contributing to the production of odor and evaluating the characteristic of odors. Methods: Complex odor and 17 odorous compounds were measured at 18 waste transfer stations located in Seoul. Results: The dilution ratio value of complex odor ranged from 4 to 30 times in the boundary layer of 18 waste transfer stations. At 6 measurement points among the 18 waste transfer stations, the dilution ratio values exceeded standards (15 times). When the results were evaluated in terms of their contribution to the formation of malodor, the patterns indicated that the highest concentration values in the residential waste disposal process were of i-valeraldehyde and acetaldehyde, while butyraldehyde and acetaldehyde accounted for a large proportion of odorous compounds from the waste recycling process. Conclusions: It was found that butyraldehyde and acetaldehyde were the primary compounds released from the food waste disposal process. Overall, aldehyde compounds were the greatest contributor to detectable odor intensity emitted at the waste transfer stations.

Increasing the mode transfer volume between public transportation modes has known to be necessary for efficiency improvement of public transportation system operation and it is also found to be important to have relevant transfer point selection with reflection of current travel pattern. This study is in regards to providing a selection guideline for the location of transfer point between public transport modes. This case study has been carried out for Daegu Metropolitan City especially for public transportation users behaviour by analysis of daily usage of transportation card to identify the transfer travel pattern. A cluster analysis was applied to categorize the pattern of transfer stop which induces many users and a discriminant analysis also utilized for grouping the stops by number of transfer trip. This research produces the estimation result of transfer volume for urban railway system no.3 in Daegu City which is currently under construction. In addition, the locations of transfer center has also been proposed.

The purpose of this study is public and Private transfers in the elderly life satisfaction, self-esteem any influence to understand. Analysis of the frequency analysis, T-test, ANOVA, regression analysis was performed. Study the following points were discussed. First, the elderly public transfer and Private transfers in accordance with life satisfaction, self-esteem was significant. Second, private transfers from children in public transfer income subsidies and the more life satisfaction and self-esteem, respectively. Third, the private sector of private transfers. Individual grants fewer higher self-esteem. Based on these results, the following suggestions were Economic independence of the elderly a chance to increase the self-esteem that was found. Therefore, a more practical and should be supported by specific public transfer system.

The paper tests the above socio-cognitive model with four empirical case studies of leading Korean science and technology research and technology transfer organizations. The case studies demonstrate clear differences in individuals' frames about the technology transfer process and arising conflicts. As a result, technology transfer process is not fully controllable and is highly contextual. We argue, whereas public policy in countries approaching technology frontier provides essential support for defining and exploiting best practices (routines/pathways) for technology transfer at organizational level, they have not matured enough to support the timely identification and resolution of conflicts between individual actors, hence the inefficiencies. Therefore, among others, public policy for technology transfer could consider allowing an inclusive approach to recognition of best practices for technology transfer and innovation processes, increased social interactions between technology transfer actors, and their training on resolution of individual level cognitive conflicts.
