The safety management of a road network comprises four basic inter-related components：identification of sites(black spot) requiring safety investigation, diagnosis of safety problems, selection of feasible treatments for potential treatment candidates, and prioritization of treatments given limited budgets(Persaud, 2001). Identification process of selecting black spot is very important for efficient investigation of sites. In this study, the accident prediction model for EB method was developed by using accident data and geometric conditions of black spots selected from four-leg signalized intersections in In-cheon City for three years (2004-2006). In addition, by comparing the rank nomination technique using EB method to that by using accident counts, we managed to show the problems which the existing method have and the necessity for developing rational prediction model. As a result, in terms of total number of accidents, both the counts predicted by existing non-linear regression model and that by EB method have high good of fitness, but EB method, considering both the accident counts by sites and total number of accident, has better good of fitness than non-linear poison model. According to the result of the comparison of ranks nominated for treatment between two methods, the rank for treatment of almost sites does not change but SeoHae intersection and a few other intersections have significant changes in their rank. This shows that, with the technique proposed in the study, the RTM problem caused by using real accident counts can be overcome.

Construction of large-scale structures such as dams would be suggested actively to cope with change of flood characteristics caused by climate change. However, due to environmental, economic and political issues, dams are not ideally constructed. Thus flood damage reduction planning projects would get started including washland or detention pond for sharing the flood in basin. The washland made artificially by human being is an area of floodplain surrounded by bank to be intentionally inundated by overflowing through overflow structure adjacent to main channel during flood season. Flood reduction capacity at just downstream of each washland could be affected by type, length, and crest elevation of overflow structure in addition to shape of design hydrograph, storage volume of washland, etc.. In this study flood reduction effects of washland are estimated for overflow weir type and gate type to compare the results of flood reduction respectively subjected to given hydrograph in sample site, the Cheongmicheon stream. It has been shown that even if gate type at overflow structure could yield more flood reduction than overflow weir type, economic aspect such as initial cost, operation cost and maintenance cost should be considered to select the type of overflow structure because flood reduction rate by gate type could not be significant value from engineering point of view.

In line with the government's policies for localization, furniture industry in the northern area in Gyeoggi-province at presence has been operated by several furniture industrial complexes in the region in small scale, but now it should be considered from overall view of furniture industry in order to develop more competitive industry. As a matter of this fact, Gyeonggi-province should be engaged in planning to make various industrial clusters of the furniture-related industry based on the northern area of province at structural as well as politic aspects, with the help of the analyzed status of the current furniture industry in region, in supporting them by the systemized policies and developing the overall program to foster furniture as an international-competitive industry. Therefore this study suggested 'furniture industry center' which will exclusively handle and maintain the network of each furniture company in the northern area of Gyeonggi-province and 'high-tech furniture industry complex' to keep pace with the globalization and to be competitive internationally and also 'common brand business' for the cooperation at technical phase. In order to realize and vitalize such suggestions, it is urgently necessary that the network consists of the furniture companies and the expert of the related department in local universities as the main body for furniture industry, of course Gyeonggi-province as well.

In order to establish fundamental data for stream restoration and environmental flow, we investigated fish fauna, community and physical habitat conditions in the Dal Stream of Han River Basin. Field monitoring including fish sampling was conducted from September 2008 to October 2009. A total number of fish caught in the 5 sites was 2,080 representing 9 families 35 species, and 19 species (54.3%) including Acheilognathus koreensis and Iksookimia koreensis were Korean endemic species during the study period. The most frequently found species in number was pale chub (Zacco platypus, 25.7%, n = 632) followed by Coreoleuciscus splendidus (18.0%, n = 375) and Z. koreanus (13.0%, n = 272). The lower reach of Dal Stream was more abundance of species, high diversity, evenness and richness, and lower dominance index than those of the upper reach. According to the dendrogram established at 0.63 level of similarity rate, sampling stations were divided into 2 groups. Most of upper streams in Korea consist of riffles and runs that are repeatedly followed by another one. However, stream channelization and leveling have caused reduction of habitat diversity. Therefore, it is necessary to make an effort on stream rehabilitation with evaluation of physical habitat condition by indicator species in order to maintain biodiversity and perform ecological restoration.

Recently, although many government agencies, including the Korea Tourism Organization, have been operating two-way interactive online idea proposal communities in order to reflect the various ideas of citizens in business, the utilization rate is still extremely low due to the lack of public's understandings and management's commitments. Therefore, based on previous studies on the characteristics of information quality, this research (1) derives key factors constituting idea quality in the context of online idea proposal communities, (2) classifies them into the content cues (value-added, relevancy, originality, and completeness) and the non-content cue (amount of writing) according to the heuristic-systematic model, and (3) finally validates how these content/non-content cues influence the knowledge adoption of administrators in an online idea proposal community. The findings of the structural equation modeling analysis with all of the 240 completed idea proposals in the 'Tourism Idea Bank' of Korea Tourism Organization reveal that, among content cues, value-added, relevancy, and originality have a significant effect on knowledge adoption. Moreover, it is also found that amount of writing as a non-content cue has a positive moderation effect on the relationships between originality and knowledge adoption.

This study aims at establishing a knowledge transfer system between academics and industries in the Chungnam Region. We analyze the difficulties encountered by the technology licensing offices of universities in the Chungnam Region through a practical analysis of the current situation regarding the transfer of the knowledge developed in the universities. The problems found included the poor circumstances of the TLO of the universities, very limited number of requests for knowledge transfer by the companies, distrust of university technologies and the absence of related networks and platforms. Especially, there is insufficient concern and recognition of the regional actors in the knowledge transfer system. Therefore, in order to improve the regional competitiveness, these problems should be fixed by enacting suitable government policies.

As the Korean government initiates the Han-style campaign, the efforts and expectations for the modernization and industrialization of Hanok are growing. Accordingly, a major R&D project sponsored by the government is in progress for the development of related technologies, in which the development of a Hanok design support system based on Building Information Modeling(BIM) technology is included as one of the major subjects. However, the development of design tools for Hanok so far has not focused on the windows and doors, which is another major element of Korean traditional architecture. Therefore, this study developed a BIM-based design tool for Hanok windows and doors as an approach to the integrated design of various Hanok elements and their applications to modern buildings. To this end, the characteristics of Hanok windows and doors were analyzed first in terms of the location, opening method, style, components, and the over-all construction. A design tool was then developed with the parametric modeling functions of the $ArchiCAD^{(R)}$system. The applicability and efficiency of the developed tool were verified with design simulations. This is expected to contribute to not only the application of Hanok windows and doors to modern buildings but also to the further development of an integrated Hanok design system.

This study was a qualitative study performed to understand the nature and structure of the suicide attempt process experienced by maladjustment soldiers. The survey participants targeted 10 soldiers who entered 'Camp Green' due to lack of duty by the 00 Corps of ${\bigcirc}{\bigcirc}$ Prefecture. Data were collected by individual in-depth interviews from October 2016 to September 2017 and analyzed using Colaizzi's phenomenological method. The suicide attempt process by maladjusted soldiers was delineated into four categories such as 'A prison without bars', 'Walk on eggshells', 'A pretentious series of life', and 'A life of desperation'; 9 theme clusters; and 25 themes. As a result, maladjusted soldiers had a generally negative experience related to military culture. Soldiers who fail to adapt to military culture will show extreme behavior unless they are able to overcome their depression. Unless specific understanding of the suicide attempt process is attained, the suicide prevention policies of mission-maladjusted soldiers will be ineffective. The results of this study hope to serve as the basis for a suicide prevention and nursing intervention program.

Microfinance has been an important tool for the economic growth and poverty alleviation. But the success factors and risk factors have not been synthesized in academic literature. This article has paid attention to success factors and potential risk of the Grameen Bank. Grameen Bank methodology is almost the reverse of the conventional banking methodology. Conventional banking is based on the principle that the more you have, the more you can get. Founder of Grameen Bank, Professor Yunus pointed out that, "The least you have the highest you have the priority to receive a loan". On the basis of theoretical literature, there have been different kinds of success factors of microfinance observed in this paper. Key success factors of Grameen Bank are like these: innovation, strict administrative structure, adaptation and learning practice, incentive system. Complementary services such as business consulting and brokerage will contribute to borrowers' economic performance development.
