In order to analyze the potential rise of ground surface of grounding grid installed in buildings, the grounding simulator has been designed and fabricated as substantial and economical measures. This paper describes the study of touch and step voltages with grounding grid where earth leakage current is injected. To assess risk voltage of grounding grid, the grounding simulator and CDEGS program were used to obtain measured data and theoretical results of this study. The grounding simulator was composed of an electrolytic tank, AC power supply, a movable potentiometer, and test grounding electrodes. The potential rise was measured by grounding simulator, and the touch and step voltages were computed by CDEGS program. As a consequence, the touch voltage and step voltage above the grounding grid were very low, but were significantly increased near the edge of grounding grid.

The Purpose of this paper is to analyze of community space of high-rise housing as a basic research towards developing a model of spacial convergence. For this, 10 cases of high-rise housing complexes are compiled. Research methods are as follows. First, through the analysis of 10 high-rise housing complexes, the types of community space program are categorized by concepts. Second, community space plans are analyzed by floor. The results of this study are summarized as follows. First, through the analysis of 10 cases, the types of community space program are classified 8 categories : Culture, Health, Leisure, Education, Life-style Assistance, Business Assistance, Open Space, Commercial Facility. Second, community space plans are arranged at the lower floor of the building at a high ratio. Third, the types of convergence model for community programs are suggested by 4 categories : Human, Time, Experience, Local Community. Fourth, community space configuration is categorized by 4 types.

At design stage of new motor or when taking remedial action of old motor, a lot of information can be obtained from thermal parameters analysis. This study focused on the temperature rise of TEFC induction motor with respect to various thermal parameters. Frame heat transfer had the most important effect on coil temperature rise. But those of air gap and rotor fan had no effect. This fact shows fan action is more important than fin action in the case of rotor fan. Coil temperature can be more decreased by cooling near the heat sources than any other parts from the results of thermal conductivity and loss tests. Variation of cooling air flow rate and motor volume effects on coil temperature were also tested. These tests suggest that improvement of cooling fan performance is important in reducing the coil temperature rise. Thermal equivalent program was verified by comparison of some experimental results.

Single-parent families are on the rise because of the death of one parent for various disasters and rapid rise of divorce, single-parents suffer various stress such as economical difficulties and emotional confusion like domestic duties, nurturing, remarriage originated from the lost of one spouse. Especially the purpose of this study was to develop family life education program focused on single-fathers. This program was developed in the viewpoint of the family consolidation. The program was composed of 3 dimensions; the stress management from domestic duties, the guideline of child nurturing, and the good remarriage. And the trial method and assessment method were suggested. The advantages of this program were the objects and contents : This program put the focus in the single-fathers which were ignored in other researches, and in the source of anxiety of single-fathers originated daily family life. This program will provide useful data for an intervention of proper welfare policy of single-father families.

The objective of this study is to analyze the space usage and user evaluation of community facility in High rise Mixed-use Apartment. This study was conducted case study and questionnaire survey. Four High rise Mixed-use Apartments built since 2000 were chosen for case study and 166 residents were collected for questionnaire survey. The frequency, percentage, mean, t-test and F-test were executed through SPSS for Win 12.0 statistics package program. The types of community facilities of High rise Mixed-use Apartments were consisted of sports, child care/study, information sharing, leisure/cultural facilities. The usage percentage of community facilities increased since the residents have moved to their current residence of High rise Mixed-use Apartments from their previous residence. The most satisfactory facility was sports facilities. The satisfaction of community facilities showed high in general. The satisfaction of community facilities was significant with gender and age.

초고층 건물이라는 특수 장소에서 화재가 발생하였을 경우에 야기될 수 있는 제반 문제점을 도출하여 인적, 물적 피해를 최소화하기 위해서 초고층 건물 내에 존재하는 잠재위험요인을 찾아내 위험이 얼마나 큰가를 분석하여 그 해결 방안을 모색하여야 한다. 예방적 측면에서 화재예방활동을 통하여 화재의 발생을 억제하거나, 진압적 측면에서 화재발생과 동시에 초기 진화하는 것이겠지만, 화재의 진행과정을 미리 예측하거나 진행경로를 차단하는 인텔리젠트 또는 파이어 그리드를 이용한 과학소방적 진압방안의 도입이 필요하다.

Within residential high-rise market there are many value determining factors. Site condition, view, program, units and structure are important parameters that are directly related to the financial aspect of the project. However, most of the studies of high-rise building design focus on the facade and the shape strategies from an esthetic point of view without considering these factors. The objective of this study is to investigate new design approach that incorporates site, program and structural information at an early stage as a generator of building form and explore a wide range of strategies to negotiate these factors in the process of design/decision making. Not being based on designer's subjective preference or style, architects still can create interesting building design through integration and negotiation of various building information. Since this form is based on real data, not just play of form, we can expect that this form has great potential to be developed into real one at the later design phase.
