One of the key features of the Korean labor market is that, even though the central axis of employment has shifted from manufacturing sector to service sector, the ratio of part-time work is very low. Its major reasons are low wage rate, insufficient fringe benefits including social insurance, and deficient job security, even though part-time work has positive characteristics. This study examines whether part-time work would be a decent one and an alternative to full-time work by answering two questions: one is who chooses part-time work and another is whether part-time work is satisfactory. Analyses of 3,971 wage workers in the 8th wave of the Korea Labor and Income Panel Survey reveal that, as expected, part-time work is prevalent among the young, married women, and the old supporting the results from previous studies and that choosing part-time work on one's initiatives has a significant positive effect on job satisfaction for women while it is not for men. Form the result, it can be concluded that part-time work can be an appropriate alternative for full-time work if one chooses it voluntarily.

The transfer of R&D performance is the technology transfer in a narrow sense. This study aimed at fanning the effective managerial systems of the transfer of the academic entrepreneur's R&D performance. For this purpose, this study analysed the characteristics and success factors of R&D performance transfer based on the theory of project life cycle. This research classified the life cycle of academic entrepreneurs' R&D projects into six stages. And the risks associated with the transfer process was categorized using the case study about the establishing processes the mineral-related small finns. Especially, the risk of the technology transfer was investigated by the R&D project implementation stages. Based on this results, this paper suggested the strategic system such as the marketing-oriented thinking, the clear-cut statement of the role among the stake-holders of the R&D and commercialization processes, the dynamic system of the academic entrepreneurs' leadership, the formation of the transfer management system, and the usage of project risk management techniques.

Recently domestic companies have been needed to securing competitive techniques due to increasing orders of plant industries in the oversea construction market. Although domestic engineering companies have been assessed competitive in the field of detail design, their high value-added basic design have evaluated uncompetitive. To manage efficiently various contents which occurred in works of design steps, the management method must be built. In this study, we have found the contents which required to management through the definition of main works and analysis of characteristics in the step of basic design. Then, we have suggested to Contents Classification System which reflected of work flows and relations among stakeholders. Proposed Contents Classification System will help us when requiring the proper documents, drawings, sheets and other information.

In the mobile telecommunication industry, the effects of handset subsidies are revealed as two aspects. There are the activation of service and handset market and the acceleration of related technology development in the desirable aspect. On the other hand, the rise in service rates and the squandering of the related resources in the undesirable one. There have been a lot of researches that disclose the desirable or undesirable factors through the qualitative methods. However, the quantitative studies are rare. In this study, we consider the positive, from the increase of demand, and negative, from the increase of service rates, effects on consumers' benefit attendant handset subsidies. Then, we quantitatively compared between the positive and negative effects and analyze the direct effects of consumers' benefit of handset subsidies, and figured out that the direct effect is not expected to be positive.

To improve the efficiency of PDP TV, it should minimize the power losses transpired during AC-to-DC power conversion and PDP driving process. Generally the input power supply for PDP driving employes a two-stage power factor corrected converter, and it independently consists of sustain driver, which has high power consumption. However, such a circuit configuration has a difficulty for the PDP market requires low cost. To alleviate this problem, a new circuit composition is presented. It integrates input power supply with sustain driver in a single power stack. The input power supply of the proposed circuit has a single-stage structure to minimize power conversion loss, and it directly supplies power to the sustain driver so as to reduce the system size and cost.

We can use NAT(Network Address Translation) technology to solve the lack of IP address. The problem of NAT traversal is happened when the filtering characteristics of NAT remove the packet that has no binding in the address translation table of NAT. There were many kinds of way to solve these problems by using additional device. Lately, network market is changed into integrating wired and wireless network by the IMS(IP Multimedia Subsystem). The IMS integrates to control network of wired and wireless network, has emerged to control convergence network effectively. Lately, the additional devices like IBCF(Interconnection Border Control Function) and IBGF(Interconnection Border Gateway Function) are used to solve the NAT traversal problem in the IMS. In this paper, we propose the solution of NAT traversal using P-CSCF without any additional equipment in the IMS.
