  • Taking a subway shield tunnel in a certain section of Zhengzhou Metro Line 5 as an example, the field tests of shield cutting cement-soil monopile composite foundation were carried out. The load and internal force of the tunnel lining under the action of composite foundation were tested on-site and the distribution characteristics and variation laws of earth pressure around the tunnel under the load holding state of the composite foundation were analyzed. Five different load combinations (i.e., overburden load theory + q0, Terzaghi's theory + q0, Bierbaumer's theory + q0, Xie's theory + q0, and the proposed method (the combination of compound weight method and Terzaghi's theory) + q0) were used to calculate the internal force of the tunnel structure and the obtained results were compared with the measured internal force results. The action mode of earth pressure on the tunnel lining structure was evaluated. Research results show that the earth pressure obtained by the calculation method proposed in this paper was more consistent with the measured value and the deviation between the two was within 5%. The distribution of the calculated internal force of the tunnel structure was more in line with the distribution law of field test data and the deviation between the calculated and measured values was small. This effectively verified the rationality and applicability of the proposed calculation method. Research results provided references for the design and evaluation of shield tunnels under the action of composite foundations.

  • Purpose: This study was aimed to identify the major factors affecting performance in health promoting behaviors in women workers at small-scale industries. Method: This study was based on the Pender's Health Promotion Model. The subjects for this study were 251 women workers at 23 small-scale industries in Busan city. The data for this study was collected from July 15th to August 15th 2003 by structured questionaries, and were analyzed with ANOVA, t-test, Pearson' correlation coefficient, and multiple Regression in the SPSS/WIN 10.0. Result: The mean performance of the health promoting behavior was 2.56. The factors related to the performance of the health promoting behaviors were social support, marital status, status of owning a house, perceived barriers to action, working time, and self-efficacy, and they explained 58.4% of the variance of the health promoting behaviors. Conclusion: The mean performance of the health promoting behavior seemed to be low, and the most important variable related to health promoting behaviorsof women working at a small-scale industry was social support. Therefore, intervention programs to increase the social support for women worker need to be developed.

  • Purpose: This study was conducted to examine effects of a small group-based cardiocerebrovascular disease (CVD) prevention education program on knowledge, stage of change and health behavior among male bus drivers with CVD risk factors. Methods: A non-equivalent control group pretest-posttest design was used. Participants were 68 male bus drivers recruited from two urban bus companies. Participants from the two groups were selected by matching age, education and risk factors. Experimental group (n=34) received a small group-based CVD prevention education program 8 times over 6 weeks and 3 times through telephone interviews at 2-week intervals. Data were collected between December, 2010 and March, 2011, and were analyzed using chi-square test, t-test, and repeated measure analysis of variance with SPSS/Win18.0. Results: Experimental group showed significantly higher scores in CVD prevention knowledge (p<.001) and health behavior (p<.001) at 6 and 12 weeks after intervention. Participants in pre-contemplation and contemplation stages made progress to contemplation and action. This was significantly better at 6 and 12 weeks after intervention (p<.001). Conclusion: Results suggest that small group-based education programs for CVD prevention are effective in increasing knowledge, stage of change, and health behavior to prevent CVD among male bus drivers with CVD risk.

  • Today, the availabity of usable pieces of land in urbanized areas is very limited. Specifically, it is very difficult to secure a piece of land to be used as a park for the public, mainly due to the high price of land in cities. However, the City of Seoul has carried out three action plans to secure land deemed for insufficient parks and to vitalize these small piece of land in downtown areas such as following: 1. Ssamzie-park(Korean version of a 'vest pocket park') Development Plan in 1990 through 1991. 2. Modernization Plan for Children's Parks since 1994. 3. Maeul-madang (Korean version of 'community garden')Development Plan since 1996. The purpose of this study was to present some design approaches for practical use of small urban spaces by articulating the concepts of Modernization Plan for Children's Park and Maeul-madang Development Plan of the winning entries and by describing how the concepts were actualized in reality.

  • 이 연구는 중소 SI업체들이 IT프로젝트를 수행하는데 있어 어떤 공통적인 특성을 보여주는가를 알아보기 위해 진행되었다. 이 연구에서는 2006년부터 2009년까지 중소 제조업체를 대상으로 수행된 194개의 IT프로젝트에 대한 388건의 감리보고서를 기초자료로 사용했다. 연구 결과 프로젝트 관리 분야에서는 일정관리가 가장 취약한(문제가 있거나 또는 관리가 잘안 되는) 것으로 드러났으며, 개발 및 구현 분야에서는 시험 계획과 활동이 가장 취약했으며, 운영 빛 유지보수 분야에서는 사용자/운영자판 위한 매뉴얼 작성이 가장 취약한 것으로 드러났다. 결국 이들 세 가지 취약한 항목들은 중소 SI업체들이 IT프로젝트를 수행하는데 있어서의 공통적인 특성이라고 할 수 있다.

  • 소상공인이 한국 경제에서 차지하는 비중이 높지만 전문적인 경영 역량이 부족하여 어려움에 처하는 경우가 많다. 그러나 이에 대한 실효성 있는 대안은 부족하다. 소상공인의 경영 문제에 관한 학계의 관심은 주로 성공적인 소상공인의 특징을 밝히거나 요인들 간의 관련성을 살펴보는 기술적이고 정량적 데이터 위주의 단편적 성과에 머물렀다. 한편 실질적인 경영 지원 과정을 통해 획득된 지식과 경험들을 이론적으로 논의하는 실천적 연구 성과는 찾아보기 어려운 형편이다. 2015년 6월부터 2015년 11월까지 경기도에 소재한 소상공인 업체들과 경기도 소재의 대학 및 경기도 소재의 중소기업진흥 기관이 공동으로 추진한 컨설팅 프로젝트에 실행 연구법을 부분 적용한 결과 트리플 힐릭스 이론 기반의 소상공인 컨설팅이 바람직한 결과를 가져온다는 사실을 알 수 있었다. 업체와 대학 그리고 공공 기관의 협업은 경영학을 배우는 학생들의 문제의식을 높이고 지식을 활용하는 기회를 부여하는 등 경영교육 상 목적 달성에 적절함도 확인했다.

  • A 2D comic model, a comic-style line drawing model having only eyebrows, eyes, nose and mouth, is much easier to generate facial expressions with small number of points than that of 3D model. In this paper we propose a 3D emotional editor using a 2D comic model, where emotional expressions are represented by using action units(AU) of FACS. Experiments show a possibility that the proposed method could be used efficiently for intelligent sign-language communications between avatars of different languages in the Internet cyberspace.

  • This paper is devoted to illustrate some numerical procedures to solve the boundary equilibrium problems of three-dimensional solids that are subjected to thermal strains. The constitutive equations take into account the bounded tensile strength of the material and they are presented in the framework of non-linear elasticity and small strains. The associated equilibrium problem is solved numerically by means of the finite element method and the numerical techniques, i.e. the Newton-Raphson method and the secant method, are revised in order to assure the solution convergence of the discretized problem. Some numerical examples are illustrated.

  • Insects have many excellent features and functions in their small bodies, such as hexapod walking, flapping flight, vision systems, sensory hairs, etc, and those characteristics can be thought as good models for many types of robots. Insects also will be good models far micro-machines because of its size. Insect behavior consists of simple reflex acts and programmed behavior, Some robots were made in order to clarify the emergent mechanism of insect behavior, Through some experiments it would be found that even if insect behavior consists of some simple action patterns, it looks intelligent through interactions its sensors and actuators with its complex environment. In the near futures small robots inspired by insects will be used in many fields of our life. I hope that insect-model based robots will play an active part in many fields and that they will make us happy.

  • Signal transduction through G protein-coupled receptors comprises three functional components, a receptor, a G protcin and a effector protein. Work over the last sevcral ycars has led to the characterization or virtually all of the components or these systems. what has come out or those studies is that these mechanisms of signal transduction are pervasive in nature being found in mammalian and avian species, as well as lower organisms such as yeast and slime mold. It is known that G protein-coupled receptors mediate the action of such diverse molecules such as small hormones and neurotransmitters, small peptide molecules as well as glycoprotein hormones and various sensory perceptions such as light, olfaction and most likely taste.
