This study is about the reinforcing type of reinforcement method which is reinforced in tunnel portal of tunnel with bad ground condition. Generally, it is known that the horizontal reinforcement method is more effective than the conventional reinforcement method. However, as a limitation of the tunnel construction technology, it is being constructed by the superposition reinforcement method. In recent years, high-strength large-diameter steel pipes and horizontally oriented longitudes (L = 30.0~50.0 m) construction technology have been developed. Therefore, it is required to study reinforcement method of tunnel portal reinforcement method. Therefore, 3-D numerical analysis (Midas GTS NX 3D) was performed by setting the reinforcement method (No reinforcement type, overlap reinforcement type and horizontal reinforcement type) and ground condition as parameters. As a result, it was considered that the reinforcement effect was the largest as the horizontal reinforcement type of the reinforcement method was the smallest in the displacement and the support material stress. Based on the results of the numerical analysis, horizontal steel pipe grouting was applied to the actual tunnel site. The displacement of the tunnel portal and the stress of the support material occurred within the allowable values and were considered to ensure sufficient stability.

This article introduces a recent innovation in Korea's human resources development policy in the SW sector. Facing serious problems in cultivating SW engineers such as a mismatch in supply and demand of SW workers, shortage of globally competitive SW professionals, and insufficient education and training of university graduates, the Korean government has decided to adopt a new paradigm in national SW engineering education, based on supply chain management (SCM) in manufacturing. SCM has been a major component of the corporate competitive strategy, enhancing organizational productiveness and responsiveness in a highly competitive environment. It weighs improving competitiveness of the supply chain as a whole via long-term commitment to supply chain relationships and a cooperative, integrated approach to business processes. These characteristics of SCM are believed to provide insight into a more effective IT education and university-industry collaboration. On the basis of the SCM literature, a framework for industry-oriented SW human resources development is designed, and then applied in the case of nurturing computer-software engineers in Korea. This approach is expected to fumish valuable implications not only to Korean policy makers, but also to other countries making similar efforts to enhance the effectiveness and flexibility in human resources development. The construction of SCM-based SW HRD model is first trial to apply SCM into SW HRD field. The model is divided into three kinds of primary activities and two kinds of supportive activities in the field of value chain such as SW HRD Council, SW demand and supply plan establishment and the integration of SW engineering capabilities that contribute the reduction of the skill and job matching through SW HR demand and supply collaboration.

The purpose of this study is to propose strategies for enhancing competitiveness through the utilization of policy funds, especially in the start-up companies supported by the Korea Credit Guarantee Fund. And then, the Korea Credit Guarantee Fund should develop 'user-centered policy funding model' in order to increase start-up's utilization of policy fund and support start-ups that are supported in the long run. The competitiveness of domestic start-up companies has been strengthened by 'user-centered policy funding model' and new innovations have been introduced through 'Living Lab', an open innovation. But, in order to overcome the limitation of reaching the stage of commercialization, the 'user-centered policy funding model' proposed in this study enables start-ups to be the subject of actual policy funding, and also allows users to freely apply for necessary funding at any time. Therefore, the Korea Credit Guarantee Fund has a significance in suggesting 'user-centered policy funding model' as a support model to be customized. However, since SMEs recognize the actual situation and limit acceptance of all the difficulties, the systematic analysis of the actual situation of the policy funds of the start-up by the credit guarantee fund and the related support institutions for the scientific approach of the user-oriented policy funding model need.

The existing HiPassPlusCard system is composed of the HiPassPlusCard, a Purchase SAM, a Purchase terminal, a settlement system and OBU. However, this system is confronted by the problem with its incompatibility. This problem occurred because the technology companies made cards in their own ways in respect of the parts which were not yet set by KS standard. Thus if existing HiPassPlusCard user wants to use any other public transportations, user would have to buy other cards and have to bring all them. Also if the HiPlusCard wants to extend their business to apply its technology into infrastructure of the other companies, the HiPlusCard has to construct infra independently so that it causes the such problems of duplicated investment. To solve these problems, we have analyzed and upgraded the existing HiPassPlusCard system, and we designed and developed the Nation-wide Interoperable HiPassPlusCard system. Then the conformity test demonstrated that it is efficiency-oriented and technically performs well. Also we, the HiPlusCard, the Korea Financial Telecommunications & Clearings and the KORAIL NETWORKS, run the Test-bed in Gwangju for 6 months. The test-bed indicated that Nation-wide Interoperable HiPassCard system practically works well.

Could STS throw another-colored light on the Hwang's Affair, the scientific fraud committed by Hwang Woo-Suk and his research team in Korea? And could analytic tools of STS unfold another meanings which have been overlooked in most of the traditionally social-sciences-oriented analyses? In this essay, I try to answer these questions by analyzing the Hwang's Affair in the view of STS, especially by using some concepts of actor-network theory(ANT): movement, translation and displacement. I want to say that the Hwang's Affair seems to be a part of normal scientific activity, not an abnormal phenomenon, and as an evidence, focus on the similarities of their life styles between "pure/real scientist" Louis Pasteur and "impure/political scientist" Hwang Woo-Suk. I try to mobilize some concepts of ANT, especially movement, and find out why scientists came to move toward the opposed direction on the pure/real-impure/political line. I suggest that there exists "laboratory politics" as the key factor in this bifurcation. My tentative conclusion is that Pasteur can take a position to make his great world, so-called the Pasteurian world, owing to the success of "double movement" in which he treated his laboratory as a fulcrum to lift up the world, but Hwang degrades himself to "ugly scientific politician" due to the loss of the momentum of his movement; Hwang treated his laboratory only as the symbolic resources and in turn failed to solidify material entities, his real political resources, even though he knew the importance of laboratory.

In Korea, recently, efforts have been made to introduce BIM(Building Information Modeling) to housing complex projects. However, there have been several problems including excessive competition for building design and outcome-oriented evaluation due to a lack of clear evaluation criteria and poorly organized management process. Under this circumstance, the study surveyed opinions of project managers and conducted a pilot test to improve evaluation criteria of BIM-based design for housing complexes. The objective is to assess the level of BIM technology and its applicability, and to propose a list of reasonable evaluation criteria for better project management. First, the study examined the current condition of evaluation on the BIM-based housing complexes, and identified 15 preliminary items that might be suitable for application of BIM. Second, the study conducted a pilot test for the 15 items to determine their suitability for the level of BIM technology, clarity of the calculation process, and the extent of fulfilling information quality, and short-listed eight items for application of BIM. In particular, in the design concept stage, mostly 3D visual images and area-related items are suitable for BIM-based evaluation. Accordingly, formerly used items such as project cost, energy and environmental analysis, building structure, and facilities were deemed more relevant to the subsequent stages of basic design and its implementation.

In recent years, efficient energy management technologies are required, as environmental problems have emerged worldwide. In response to this, smart home services focused on efficient energy management technology seems to be emerging. And the integration of technology of user-oriented real-time energy monitoring and control systems is required. In this paper, we present a location-based green home service using smart phones for efficient energy management in a house. We design a green home network system to apply the green home service, and implement an integrated gateway system which connects and controls each appliance in a house. We develop appliance control services and indoor location services on smart phones, and determine whether user's occupancy of each room by measuring the location according to the variation of signal strength. In order to evaluate the performance of the energy savings, we have set up the scenarios of energy usage pattern and have compared the energy variation resulting from the application of the indoor location services with smart meters. A comparison of energy usage demonstrated that the energy saving of a house with the proposed location-based green home service was down up to 30%.

This study suggests multisensory interaction techniques to help visually impaired people appreciate and understand artworks through non-visual senses such as tactile, auditory, and olfactory senses. A user study was conducted on the basis of a qualitative interview about the experience of appreciating artwork through the multisensory interaction system to visually impaired people so as to verify the development of the interaction techniques. The user test shows that the multisensory interactions in artwork generally not only help them appreciate and understand it but also give them satisfaction through artwork appreciation. However, it also indicates that some multisensory interactions caused the visually impaired people confusion and could not be perceived during the appreciation. On the basis of these outcomes, implications in this study are as follows. This study has contributed to providing specific development guidelines and indicators of non-visual multisensory interactions as a technical alternative to improve accessibility to cultural and artistic activities for the visually impaired. Furthermore, this study is expected to contribute to building a technical background, which can provide comprehensive sensory experiences with not only blind people but also non-blind people such as children and the elderly through universal interaction techniques beyond existing visual-oriented fragmentary experience.

Global warming crisis due primarily to continued green house gas emission requires impending change to renewable alternative energy than continuously depending on exhausting fossil fuels. Bioenergy including biodiesel and bioethanol are considered good alternatives because of their renewable and sustainable nature. Bioethanol is currently being produced by using sucrose from sugar beet, grain starches or lignocellulosic biomass as sources of ethanol fermentation. However, grain production requires significant amount of fossil fuel inputs during agricultural practices, which means less competitive in reducing the level of green house gas emission. By contrast, cellulosic bioethanol can use naturally-growing, not-for-food biomass as a source of ethanol fermentation. In this respect, cellulosic ethanol than grain starch ethanol is considered a more appropriate as a alternative renewable energy. However, commercialization of cellulosic ethanol depends heavily on technology development. Processes such as securing enough biomass optimized for economic processing, pretreatment technology for better access of polymer-hydrolyzing enzymes, saccharification of recalcitrant lignocellulosic materials, and simultaneous fermentation of different sugars including 6-carbon glucose as well as 5-carbon xylose or arabinose waits for greater improvement in technologies. Although it seems to be a long way to go until commercialization, it should broadly benefit farmers with novel source of income, environment with greener and reduced level of global warming, and national economy with increased energy security. Mission-oriented strategies for cellulosic ethanol development participated by government funding agency and different disciplines of sciences and technologies should certainly open up a new era of renewable energy.

Purpose : This study is a descriptive correlation study to offer the basic materials for developing the preventive program of continuously increasing AIDS in the young people by examining the knowledge and attitude of AIDS in college students. Methods : The period of data collection was from May 1 to 15, 2009, 300 freshman, sophomore and junior students who understood the purpose of the research and agreed to participate in the questionnaire were randomly sampled, structured questionnaire was distributed to them and their responses were collected. Instruments used for this study included those used by Kim and Lee and revised and complemented by this researcher to measure the knowledge of AIDS and those by Yun and Lee revised and complemented by the researcher to measure the attitude of AIDS. For data analysis, it measured technical statistics, t-test, ANOVA, and Pearson's correlation coefficient using SPSS/PC 12.0. Results : The results of this study are summarized as follows. 1. The whole knowledge of AIDS the subjects had scored 58.9 and their average attitude scored $3.78(1{\pm}25)$. 2. In the degree of knowledge of AIDS depending on general characteristics and health-related characteristics of the subjects, it was found that the students at the department of emergency medical showed higher knowledge(t=3.638, p=.001) and positive attitude of AIDS(t=3.330, p=.001) compared to students at other majors. 3. In the degree of knowledge of AIDS depending on AIDS-related education, subjects who had experienced AIDS education(t=1.973, p=.050), those with the experience of theory education(F=4.057, p=.008), those who felt the necessity of AIDS education(t=4.588, p=.000), and those who were willing to take part in AIDS education(t=2.898, p=.004) showed higher know1edge of AIDS. In the attitude of AIDS, subjects with theory-oriented AIDS education(F=3.012, p=.032), those who felt the necessity of AIDS education(t=2.445, p=.015), and those who were willing to take part in AIDS education(t=2.379, p=.018) showed positive attitude of AIDS education. 4. As the knowledge of AIDS the subjects was higher(r=.329, p=.000), they showed more positive attitude of AIDS and it meant that there was positive correlations. Conclusion : Consequently, systematic, concrete and continuous education of AIDS suitable to the requirements of college students is needed to induce changes of their knowledge and attitude of AIDS and for this, AIDS education program which can be used properly by the developmental stages of college students who belong to late adolescence should be developed in the field of school and if possible, curriculum of sex education including AIDS education should be established in all departments of college.
