한해 누수로 인하여 많은 양의 상수가 소실되고 있어 국가 재정낭비를 초래하고 있다. 이는 관의 노후화와 지반침하에 의한 파이프의 파손 둥 여러 요인에 의해 발생하는 것으로 누수를 예측하여 탐지하는 것은 매우 어렵다. 현재 누수를 탐지하는 방법은 여러 가지가 있지만 현실적인 제약과 경험자의 주관적인 판단에 의존하기 때문에 정확한 누수 위치를 찾을 수가 없었다. 본 논문에서는 종래의 누수탐지 방법의 단점을 획기적으로 보완하여 지하에 매설된 상수도 관망을 실시간으로 모니터링 할 수 있는 누수탐지 모니터링 시스템을 제안하였다 또한 제안된 시스템을 GIS상에서 실험함으로서 효율성과 정확성을 입증하였다.

This paper examines university patenting activities as a commercialization of academic research. It shows how a number of university patents increase exponentially and how that can be, especially in terms of role of the state. In the late 1990, the Korean government supports the new vision of 'technological innovation' in establishing a science and technological policy and begins to perceive the importance of university R&D to overcome the economic crisis. Thus, an administrative, financial, and legal systems which support the university R&D are organized and the governmental grants for R&D increase exponentially, especially in promising new technologies(6T). Also, an institution for managing intellectual property rights is established in university. Universities assess professor's performance in terms of patent and license to encourage patenting activities. Thus the number of patents and its productivity increase exponentially. But the increase in patents takes place only to a dozen of universities, this means that a Matthew effect does work.

Recent companies have introduced AEO (Authorized Economic Operator) system for a smooth and fast customs clearance to meet the conflicting objectives of trade security and trade facilitation in international trades. The present study was to verify 150 companies that have acquired Korea's AEO certification and its impact from the government and financial support, the effects of AEO certification post management, and the AEO system's utilization satisfaction to seek ways to further activate the AEO system. The research hypothesis and model was derived on the basis of existing theory and empirical research, and obtain the following results. First, government policy supporting the AEO system after certification post management showed positive (+) effect for the AEO satisfaction. Second, AEO certification post management showed positive (+) effect for AEO satisfaction. Third, government funded factor showed negative (-) effect for AEO certification post management. The present study is differentiated from previous research information. The study evaluated the company's satisfaction with the AEO certification, and the government support has empirically evaluated the relationship between the post management and the satisfaction. Academic contribution was conducted for Korea's AEO system's post follow-up research while a practical contribution suggested the direction for our country's organization to take advantage of the AEO system.

In this study, we compared Korean retirees' retirement wealth adequacy with their subjective recognition and examined determinants affecting the retirement wealth adequacy. The data were drawn from the 2007 Korean Retiree Survey carried out by the Korean Investors Education Foundation. The major results of this study were as follows. The analysis suggested that Korean retirees(age 50 and over) were not well prepared financially. When using their assets(except for their residence), only 23.2% had accumulated enough wealth to meet their expenses for the remainder of their life. 25.7% of retirees subjectively considered themselves to be adequately covered. The comparison results showed that 23.8% of retirees' subjective recognition was not in accord with the estimation results. One of the most troubling groups is the 12.9% of retirees who were in the inadequacy group even though they considered themselves to be in the adequacy group. Retirement wealth adequacy determinants were quite different between objective adequacy and subjective recognition. Household income and ownership of a residence have positive effects on the retirement wealth adequacy. Also, the importance of retirement planning to retirement wealth adequacy is statistically confirmed. Based on these findings, This research suggests private retirement planning and political implications for retirees and preretired households.

This study aims to empirically analyze the effects of the learning organization characteristics in public libraries on the innovative work behavior of librarians. In this analysis, 113 librarians from 15 public libraries in the Seoul Metropolitan Area of South Korea were surveyed to investigate the learning organization characteristics of libraries and innovative work behavior. Through a multiple regression analysis of learning organization characteristics and innovative work behavior, it was found that, among the sub-factors of learning organization characteristics, creating continuous learning opportunities and creating systems to capture and share learning had a positive effect on idea realization among the sub-factors of innovative work behavior. From this, it was interpreted that public libraries should increase financial and non-financial support for librarians to learn and also that libraries should create various systems such as electronic bulletin boards and meetings in which librarians can share their learning. Moreover, the sub-factors of learning organization characteristics were found to have no effect on idea generation and idea promotion among the sub-factors of innovative work behavior, which indicated that it will be necessary to identify the organization characteristics that affect idea generation and idea promotion. This study is significant in that it identified the sub-factors of learning organization characteristics that promote the innovative work behavior of public library librarians.

Fourth, there were five periods with establishment, foundation, crisis, restoration and collapse in the change of public policy. Fifth, $Zh{\bar{u}}z{\check{i}}^{\prime}$ and $Ch{\acute{e}}ng{\cdot}zi$ had influenced bigger than Confucius as a factors of policy making. This study has been promoted the complement of context analysis and understanding of semantic analysis with implementing dictionary using two language with Korean and Chinese.

Currently financial support for vocational skills development training is provided based on the NCS standard unit price set according to the NCS occupational classification. Such a standard unit price system has the advantage of reducing administrative burdens required in managing the training levy-grant system. In this paper, it is pointed out that current unit price system may distort the social integration function of vocational training policy as it is based on the tuition fees of training course. As a basis for finding a more appropriate financial support system, we analyzed what factors are influencing the training course fees set by training institutions. As a result, it was confirmed that the monopolistic nature of the training courses or the high level of willingness of pay of training participants influenced the training course fees. Therefore, the necessity of removing the influence of such factors from unit price system was suggested so as that the training policy contributes to the social integration. Furthermore, it is required to establish new support criteria centered on the government's policy judgment if the training costs of all training courses cannot be exactly estimated.

The main purpose of this paper is to examine the structural determinants of regional variations of poverty in Korea. Poverty rates and independent variables in Seoul, 6 other metropolitan areas, and 8 provinces except Jejudo from the year of 1998 through 2006 were pooled as unit of analysis. The pooled cross-sectional time-series regression(TSCSREG) using SAS program was adapted for the analysis. As a result of the analysis, absolute poverty and relative poverty of Gangwondo and Chungcheongnamdo were relatively higher, and that of Seoul and Ulsan metropolitan area were lower than other areas. And, the increase of financial self-reliance, social welfare expenditure, rate of standard workers, and rate of workers in manufacturing sector were associated with lower poverty rates. Therefore, place-based policies should be considered as another poverty-fighting tool in conjunction with people-based policies.

Due to various reasons (normally financial constraints in developing countries), it becomes common to change of the business model from state-run projects to Private Investment Projects (Public Private Partnership) in the global railway businesses. However, due to the nature of railroads compared with other types of infrastructure such as roads and others, railway business require considerable construction cost and O&M cost through the business development, construction, and operation and management stages. Therefore, private investment railway projects, especially in developing countries, can be problematic in terms of the potential for uncertainty when return on investment cannot be guaranteed. In order to strengthen the competitiveness of domestic companies when entering overseas railroad PPP projects, this study proposes PPP-related risks and their countermeasures by reviewing global railroad trends and identifying Korea's weakness in managing international railroad projects.
