Proprioception means the ability to perceive the sensation of position and movement of body. As it is transmitted to central nervous system and used in feed-back or feed-forward motor control, proprioception allows us to keep our normal movement and normal balance activity. However, the conditions such as injury, disease, aging and fatigue can damage the proprioceptiive sensation of position, movement and lead to a functional impairment and additional damages in musculoskeletal system, because they alter the amount of proprioceptive ability that transfer into the central nervous system. The purpose of this study was to identify the definition and the function of proprioception, to look into variations in injury, disease, aging and fatigue that can be easily met in clinical application and eventually to provide valuable aid for assessment and treatment.

The number of tunnel has fast increased with the rapid expansion of highway network. Tunnel should be designed to provide for drivers both safety and pleasant driving conditions. In this perspective, the design for tunnel lightning is very important in order to provide its safety, pleasantness, and cost-efficienty of maintenance, all of which should be considered and analyzed for a better tunnel lighting. This paper attempts to compare the low-pressure sodium lamp, which has usually been used for tunnel lighting, with the fluorescent lamp, which we consider as an alternative for the former. In an effort to determine the number of lamps to meet the required illuminance in the tunnel, this research employs a simulation technique which would allow us to conjecture, with the aid of basic model, the life cycle cost for illumination per each tunnel. This analysis is expected to provide a basic method and related information for tunnel development and design.

Through two case studies on the United States and Japan, this research aims to identify the characteristics of disaster management research and thereby provides policy implications for Korea. This paper analyzed government-funded disaster management R&D for each country: the National Science Foundation awarded projects from 2005 to 2015 for the United States, and Grants-in-Aid for Scientific Research from 2011 to 2015 managed by the Japan Society for the Promotion of Science for Japan. As a result, four following implications were drawn. 1) pursuit of R&SD(Research & Solution Development) instead of R&D, 2) shift from prevention to life-cycle management, 3) necessity of multidisciplinary research, and 4) emphasis on post-disaster investigation.

The new integrated CAD-CAM systems induce an increasing demand for simulation tools, which are able to simulate industrial part assembly processes by welding, gluing, riveting or bolting(more generally by fastening). Concerning fastened flexible parts, there exist no efficient computational aid on tolerance and methodology available on the field. The first part briefly presents the approach method based on the finite element method for TADA(Tolerance Analysis of Deformable Assemblies). The second part compares the results obtained by simulation using the commercial FEM code with the measurements. The principal elements of dispersion have been identified and studied on an experimental basis in order to test the robustness of the TADA model. This has enabled us to verify the model's possibilities as regards industrial constraints such as the use of incompatible meshes or the use of triangular elements and so on.

This paper studies the dynamic foundation-soil-foundation interaction for two square rigid foundations embedded in a viscoelastic soil layer. The vibrations come from only one rigid foundation placed in the soil layer and subjected to harmonic loads of translation, rocking, and torsion. The required dynamic response of rigid surface foundations constitutes the solution of the wave equations obtained by taking account of the conditions of interaction. The solution is formulated using the frequency domain Boundary Element Method (BEM) in conjunction with the Kausel-Peek Green's function for a layered stratum, with the aid of the Thin Layer Method (TLM), to study the dynamic interaction between adjacent foundations. This approach allows the establishment of a mathematical model that enables us to determine the dynamic displacements amplitude of adjacent foundations according to their different separations, the depth of the substratum, foundations masss, foundations embedded, and the frequencies of excitation. This paper attempts to introduce an approach based on a polynomial mathematical tool conducted from several results of numerical methods (BEM-TLM) so that practicing civil engineers can evaluation the dynamic foundations displacements more easy.

After participation in the Colombo Plan in 1954, Japan has provided Official Development Assistance (ODA) to 185 countries and areas, and the accumulated amount of Japan's ODA is approximately US$ 221 billion for 50 years. Japan is the second largest ODA donor country in the world now. The country is contributing to the peace and development of the international community. However, the recipient government and the parties concerned are not always satisfied with the Japan's ODA system.. Especially the grant aid system is strongly based on the domestic public work system. This paper analyzes the problems and figures out solutions from the viewpoint of donor and the participant.

본 논문은 정부의 창업지원사업이 외형적 예산투입관점에서는 크게 증가함에도 불구하고 창업기업들의 현장에서 필요로 하는 니즈에 맞게 적절하게 이루어지지 못한다는 문제에 대해, 창업지원사업을 수혜 받은 기업들을 대상으로 정부지원 세부사업에 대한 중요도와 만족도를 조사하고 이의 차이인 기대충족도를 분석하여 그 원인을 분석하고 개선방안을 제시하는데 목적이 있다. 이를 위해, 본 연구는 충청남북도에 소재한 창업기업들을 대상으로 창업가가 인식한 정부의 창업지원사업 만족도가 경영성과에 미치는 영향을 살펴보았다. 특히 본 논문은 창업지원사업 중 어떠한 정부지원이 경영성과에 가장 큰 유의미한 영향을 미치는지를 분석하였다. 연구결과는 다음과 같다. 첫째, 창업지원사업의 창업교육, 시설 공간, 컨설팅, 자금지원 각각 분야의 중요도와 만족도의 차이에 대한 통계적 유의성을 검정한 결과 모든 분야에서 유의미한 차이가 있는 것으로 나타났다. 또한 중요도와 만족도의 차이가 가장 큰 분야는 자금지원으로 나타났다. 둘째, 창업지원사업과 재무적 성과와의 영향관계를 분석한 결과 시설 공간 만족도가 재무적 성과에 정(+)의 영향을 미쳐 시설 공간 만족도가 높을수록 재무적 성과가 높아지는 것을 알 수 있다. 창업지원사업과 비재무적 성과와의 영향관계를 분석한 결과 창업교육 및 컨설팅 만족도가 비재무적 성과에 정(+)의 영향을 미쳐 창업교육 및 컨설팅 만족도가 높을수록 비재무적 성과가 높아지는 것을 알 수 있다. 마지막으로 본 논문은 기대충족도가 가장 낮은 자금지원사업에 대해 그 수치가 가장 높은 창업교육 및 컨설팅사업과 연계하여 맞춤형 지원사업을 개발하는 것을 정책대안으로 제시하였다.

The year 2010 is the 60th anniversary commemorating the Korean War. China intervened in the Korean War with the logics such as "To Resist the U.S.'s Aggression and Aid North Korea," "Save Endangered Home & defend Nation," and "If the Lips Are Gone, the Teeth Will Be Exposed to the Cold or If One of Them Falls, the Other is in Danger." However, China had a deep and long connection with North Korea through 1st Chinese Civil War, war against Japan imperialism, and 2nd Chinese Civil War. China has consulted with Kim Il-sung on his invasion of South Korea at the initial stage of development and played a casting vote role in the execution of the invasion plan. During the Korean War, the PLA supported the North Korea's regime by its action, and made the Korea Peninsula divide into two semi-permanently. Even after the war, China continues to maintain relations with North Korea by helping North Korea build the Kim Il-sung's Kingdom. Currently, whenever any issue related to North Korea rises in the international society, China definitely gets involved in those issues and exercises its power. Conditionally 'either armed aggression or, and wartime' in North Korea, China would follow the "Clause of Military Auto Intervention." In addition, China is very likely to establish refugee camps for North Koreans in the Northeastern-Three-Province and to provide rear bases or guerrilla camps for pro-Chinese sects. Furthermore, voluntarily playing a role as spokesman of North Korean Regime in the international society, China will exercise enormous influence on the reunification of the Korean Peninsula.

한 나라의 사회복지 시설과 제도로 그 나라 국민 생활의 질과 수준을 가늠할 수 있듯이, 대학의 학생복지 시설은 학생들의 대학생활에 도움을 주는 제반 시설의 질을 평가할 수 있는 척도가 될 것이다. 오늘날 대학사회의 문제점으로 대두되는 개인주의와 학과에 대한 소속감결여의 문제점을 해결하기 위한 하나의 대책으로서 학생회관이 갖는 기능적 측면을 보다 극대화하여 학교에 대한 소속감과 공동체의식의 함양에 건축적 환경을 제공하는 데 본 논문의 목적이 있다, 또한 대학인이 가장 많은 시간을 보내는 대학 캠퍼스의 바람직한 계획 방향과 학생들의 생활 전반을 지원하는 대학 복지 시설로서의 바람직한 학생회관 배치계획 방향에 관해 모색하고자 한다.
