Selective Laser Sintering(SLS) method is one of Rapid Prototyping(RP) technologies. It is used to fabricate desirable part to sinter powder and stack the fabricated layer. To develop this SLS machine, it needs effective scanning path and the development of scanning device. This paper shows how to make fast scanning path with respect to scan spacing, laser beam size and scanning direction from 2-dimensional sliced file generated in commercial CAD/CAM software. Also, we develop the scanning device and its control algorithm to precisely follow the generated scanning path. Scanning path affects precision and total machining time of the final fabricated part. Sintering occurs using infrared laser which has high thermal energy. As a result, shrinkage and curling of the fabricated part occurs according to thermal distribution. Therefore, fast scanning path generation is needed to eliminate the factors of quality deterioration. It highly affects machining efficiency and prevents shrinkage and curling by relatively lessening the thermal distribution of the surface of sintering layer. To generate this fast scanning path, adaptive path generation is needed with respect to the shape of each layer, and not simply x, y scanning, but the scanning of arbitrary direction must be enabled. This paper addresses path generation method to focus on fast scanning, and development of scanning system and control algorithm to precisely follow generated path.

The study is to clarify the influence of house heating forms on the ways in which people make use of space and react to their home environment. With a sample of 200 households in apartment houses recently built in Seoul, measurements and descriptive evaluations have been made once in winter and once in summer of 1975/76. Part Ⅰ of this study includes the result of summer survey which will be comparatively analysed with that of Part Ⅱ in the final report. The findings of Part Ⅰ are summarized as follows: 1) there is a positive indications that Westernization of life style is more predominant in the houses with modern style of heating such as pannel heating and radiator than with traditional Ondol. 2) the individual room functions and seasonal variations in room use are significantly differentiated across the heating types. 3) Peoples' attitudes toward their life style within the home environment are also differentiated across the heating types. It can be concluded that the modernization of house heating should be preceded by the better quality of life style in accordance with the space and environmental design based on the improvement of standard of living.

사우경,김용기,정회민 大韓小兒齒科學會 1991 大韓小兒齒科學會誌 Vol.18 No.2

Partial anodontia associated with Ectodermal Dysplasia, may be inherited as a sex-linked recessive characteristic. The size of the primary teeth that are present may be normal or reduced. The anterior teeth are often conical, which is one of the characteristic of oligodontia associated with an Ectodermal Dysplasia. Children with a large number of missing primary teeth can have partial dentures constructed at an early age which have been shown to improve their masticatory function and nutritional states. A ?? year-old male with Ectodermal Dysplasia showing oligodontia and a number of abnormal shaped primary teeth was treated by using anterior strip/open-faced stainless steel crowns, posterior casted metal crowns and removable acrylic partial dentures on upper/lower arches in order to rehabilitate functional and esthetic problems.

A micro former among micro machines is known as a useful tool for machining micro parts. It makes micro holes automatically with punches, a hole-shape die and material by rotation of crank shaft synchronously. Micro displacement in micro forming affects on the performance of machining because micro forming size is similar with its mechanical displacement. Therefore, the measurement of this micro displacement is essential to be guaranteed to obtain high forming precision in the whole machine as well as its devices. This paper addresses the development of a laser interferometer to measure micro displacement for a micro former. The laser interferometer is able to measure micro displacement during a few micro seconds with non-contact. For the experiment, a laser probe installed on the optical table with optical devices and a micro stage. Moving mirror set up upside of micro stage. The velocity decoding board is also added to calculate doppler shift frequency directly. The output signal is processed by LabView. Finally experiments are found out the relation between displacement and output signal.

조경은,김회수,염시창 한국교육정보미디어학회 1999 교육정보미디어연구 Vol.5 No.2

본 연구의 목적은 작문에서의 컴퓨터(워드프로세서) 사용이 최근 작문에서 중요하게 논의되고 있는 학습자의 메타인지와 함께 작문의 결과에 미치는 영향을 알아보는 것이었다. 이를 위해 광주에 있는 U중학교 3학년 남학생 80명을 대상으로 메타인지 수준별(상·하)과 워드집단과 지필집단으로 무선 배정한 후 수업시간에 작문을 하도록 하고 작문 결과와 작문 태도 검사를 통해 작문의 길이와 질, 그리고 작문에 대한 태도 및 그 상호작용 효과를 실험하였다. 실험 결과 워드를 사용한 집단과 메타인지 상위 집단의 작문의 길이와 질은 더 좋았으나, 작문의 태도나 작문 매체와 메타인지 수준에 따른 작문의 길이와 질, 태도의 상호작용 효과는 의의 있는 차이가 없었다. 이에 작문 매체와 메타인지 수준은 작문의 길이와 질에 영향을 준다는 것과, 작문의 태도 및 매체와 메타인지 수준의 상호작용 효과는 다양한 실험 설계와 충분한 시간, 워드프로세서를 이용한 작문 기회의 확대 등과 더불어 다시 논의되어져야 할 것임을 알 수 있었다. The purpose of this study was to examine the effects of media and metacognition and their interactive effects on writing quantity, quality, and students' attitudes toward writing. The subjects of this experiment were selected 80 male students from third grades at U middle school in Kwangju city. The research design was 2x2 factorial design with four groups by levels of metacognition and writing medm. On the basis of metacognition test scores, the subjects were divided into two groupshgh vs. low), and these groups were randomly assigned to ane of word-processor writing group and hand-writing group, forming four groups in total. After pretest of writing attitudes, each group were given 45 minutes writing time and took the posttest of writing attitudes after a week. ANOVA and ANCOVA were employed to analyze the data and the significance level, alpha was set at a .05 level. The results were as follows: First, the word-processing group was superior to the hand writing group in writing quantity and quality. second, the high-metacognition group was superior to the low metacognition group in writing quantity and quality. But, writing media and metacognition didn't have a significant effects on student' s attitudes. third, there was no interaction effects between the writing media and the levels of prior metacognition on writing quantity, quality and students' attitudes. Last, in the word-processing group, high metacognition subjects received higher scores than low metacognition subjects. The findmgs from this study indicated that writing media and metacognition had significant effects on writing quantity and quality, and that we must rethink

정경회,이일재 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.14 No.6

Today the sports is doing very important role in promoting the tourism industry through sports tours as well as in doing its own functions, and therefore local governments are making efforts to bring economic benefits to their region through sports. The purpose of this paper is to suggest effective policy implications for the Jeollabuk-do by researching the ways to activate sport tourism. To accomplish the purpose of this study, we have surveyed 1,000 people who are selected by the stratified random sampling method. Out of 780 questionnaires collected, we use 756 questionnaires for the descriptive statistics, and analyses of frequency, crosstable, and variance with SPSS Window 10. We have performed the pilot tests twice and extracted the questions through reliability tests. Based on the extracted factors we finally set up the questionnaire which is consist of characteristics of demography, general types and degree of satisfaction on sports tour, types of sports tour. The results of this study we obtained through data collection and analyses are as follows: First, the degree of recognition on sports tourism is generally low. Therefore, it is necessary to hold seminars or conferences related to sports tourism for the tourism specialists, physical education professionals, relevant government employees and tourism employees. The frequency of participation in the sports tourism is the most respondents participated 1-3 times. The purposes of participation in sport tourism are to spend spare time, to pursue amusement, to get rid of stresses, and to improve health. This shows that the sport tourism should give people both sports activities and tour. Second, the result shows that the sight-seeing of natural beauty and the participation of cultural events are most wanted tour products when people consider sport tourism. This agrees with the assertion that the modern tours have been changing to the 'experience tour' and 'active tour'. As competitive tour products linked with sport tourism in Jeollabuk-do, the social and natural tours are selected. Therefore it is necessary to develop these types of tours. The degree of satisfaction regarding the sport tourism in Jeollabuk-do is generally low, thus it is necessary to develop facilities and programs and to reinforce the public relations. Third, it is necessary to develop sport tourism products that are linked to the local festivals with local tour resorts. Therefore, sports tour facilities and theme parks that fit to the uniqueness of Jeollabuk-do should be developed based on the case studies from the developed countries and on the researches for sports events preferred by sports tourists.

배정익,이경희 대한건축학회 2003 대한건축학회논문집 Vol.19 No.7

The construction and property sector has seen the development of a number of methods for evaluating environmental performance and building environmental assessment schemes for existing buildings and new designs. But these Environmental evaluation methods have decision making design adaptation limitations in the evaluation process such as: 1. The lack of economic consideration of buildings. 2. The absence of a weight system among buildings' environmental performance criteria. 3. The insufficient adaptation to a vernacular construction environment. This study is aware of the aforementioned issues and will take action in the following steps: ① Laying weights on the building's environmental performance criteria, ② A presentation of Cost-Effectiveness Analysis for the economic consideration of buildings, ③ Establishing integrated environmental performance evaluation methods of alternative design considering multi-criteria and choosing an alternative design. And finally, this study presents an integrated environmental evaluation method as a decision making tool for a multi-criteria design alternative.
