大關嶺地域의 家屋形態와 機能 : 平昌山村家屋의 變貌를 中心으로
申重盛 誠信女子大學校 韓國地理硏究所 1984 應用地理 Vol.- No.7
The purpose of this study is to examine rural houses have kept its old types and how they have been changed, and to find out general trend of folk house pattern in Yongsan-ri, Dosa-ri and Shin-ri, the Pyung Chang County of the Kang Won Province. For the study I took a field trips to study area several time from 1983 to 1984. I obtained the materials and data in the field. The data was analyrized with the statistical and descriptive methods. The results may be summarized as follows; 1. Traditional folk house type of double row room type ( 址 ) which have cowshed in front of the kitchen remains in three study areas, in particular dominant in Dosa-ri. 2. Materials of roof has been changed from thatched roof to state or zinc roof, especially slated roof dominant in shinri, while the other areas with cement block by administrative policies. 3. The extension of room and Maru (Wooden floor) has been experienced recently from the part of size, which result from the change of lifemode with improvement of economic life. 4. Most of annex or attached buildings are generally situated at right or left side of the main building, making a right angle, some others irregular forms. 5. House form of Yongsan-ri has not been changed in spite of level up of economic living. Dosa-ri is expected to develop with the location of Yong Pyung Myon administrative service. Shin-ri is expected to change soon with truck farming, pavement of road and administrative policy.
송전손실보정에 의한 Newton-Raphson 전력조류계산법의 확장
신중린,임한석 건국대학교 1994 學術誌 Vol.38 No.2
Newton-Raphson(NR) method is the famous Power Flow calculation technique, and normally used due to its rapidness of numerical convergency. In the conventional NR method, however, there is a somewhat unrealistic assumption under which all the system transmission losses are considered to be supplied by the slack bus generator. In this study, a new approach for handling the losses and augmenting the conventional NR method is proposed. The proposed method estimates the incremental changes of active power on each generation bus with respect to the total system power loss, and the estimated value are used to update the slack bus power. By doing this is improves the performance of power flow calculation, especially for the critical situation which is close to voltage collapse point and thus has relatively large transmission loss.

The author has participated in the International Conference on Electrical Engineering 2004 (ICEE 2004) held in Sapporo, Japan from July 4 to 8, 2004. This is the tenth annual conference jointly sponsored by the Institute of Electrical Engineers of Japan (IEEJ), Korean Institute of Electrical Engineers (KIEE), Chinese Society for Electrical Engineering (CSEE) and Hong Kong Institution of Engineers (HKIE). The ICEE 2004 was a joint conference with Asia-Pacific Conference of Transducers and Micro-Nano Technology (APCOT/MNT 2004). The conference aims to provide a forum for sharing knowledge, experience, and creative ideas among electrical engineers worldwide. It gives me a good opportunity for better international collaboration.

본 논문에서는 고성능 표면탄성파 필터의 최적 설계를 위하여 다양한 IDT(interdigital transducer) 구조의 필터를 제작하고 각각의 주파수 응답특성을 비교 분석하였다. 기본 구조외에 MSC(micro strip-coupler), double split, reflector, ground line 등의 구조를 일반적으로 널리 사용되고 있는 Y-Z cut l-N(LiNbO3) 기판 위에 형성시켰다. 제작된 소자의 중심주파수, 통과 대역, 삽입손실등을 측정하였으며, 주파수 응답에 기초한 기존 모델의 효용성을 논의하였다. Effects of IDT structures on frequency responses of SAW filters are investigated to achieve a high performance SAW filter, Various types of IDTS, such as MSC(multistrip-coupler), double split, reflector, and ground line, are designed and patterned on a widely used Y-Z cut LN(LiNbO3) substrate. Center frequencies, band widths, and insertion losses are measured and compared. Invalidity of the conventional model based on the impulse response model is also discussed.

Soy milk prepared from soy protein isolate and soy milk fermented with Lactobacillus acidophilus were adsorbed and desorbed by using Tenax-GC method and analyzed by Gas Chromatograph. It was found that this techingue was very efficient when the analytical results was expressed by the ratis of the peak area of each volatile to that of a fixed concentration of internal standard. Acetaldehyde, ethyl vinyl ketone, n-hexanal, n-hexanol, and 1 -octen-3-ol existed in soy milk. The content of acetaldehyde and diacetyl was increased while that of n-hexanal was reduced by lactic fermentation.

The purpose of this study sis to suggest Improvement Ideas of urban squatter area through the Japan examples For this, we analyzed the six examples of Japan and extracted their Improvement methods and main principles The frame of analysis was made from the problems of urban squatter area Improvement in Korea and It's Items are social, economic, system, organization and space These Items were applied to six examples In Japan too The results of this study is as follows First, the problems of urban squatter area Improvement were summarized to the destroy of local society, the privatization of development benefit, the lack of publicity effect, the exception of residential participation and reckless development Second, they were inventing diverse Improvement methods under the local situation in japan and their main principles were durability, strategy, flexibility, cooperation and unification Third, dll examples were proceeded by the leading public role and the most important concept was not physical supply but living independence about local society The last, we were able to suggest four subjects ①the introduction of incremental small-scale development concept ②the invent of adaptable Improvement methods in local situation ③the strengthen of public support and coordinate function ④the specialization and partnership of resident, company and public

As direct contact mechanisms, cam and follower mechanisms are used commonly in many machinery. Disk-typed cam mechanisms have 4 different types due to the different type of followers, such as reciprocating roller type, reciprocating flat-face type, oscillating roller type, and oscillating flat-face type. Depending on the shape of cam and type of follower, the motion of cam-follower mechanism is determined. Thus design procedure must be well defined for determining acculately the shape of cam corresponding to the given motion of follower. In this paper, an instant velocity center method is proposed. This method calculates the instant velocity centers of cam and follower in contact motion at any time. From geometric relationships on contact points of cam with follower, cam shape can be determined using the instant velocity centers. Also this paper presents 4 different cams for demonstration of the proposed design method and the results gives the exact solutions of cam design.
