Objective: The purpose of this study is to compare the effects of Dong-si acupuncture therapy and General acupuncture therapy for the patients with acute ankle sprain. Methods : This study has been carried out for 60 cases of ankle sprain patients who have visited Dong-Seo Oriental medical Hospital from May 1, 2002 to September 30, 2002. We have treated 30 cases of them by Dong-si acupuncture therapy and the other 30 cases by General acupuncture therapy. And we have compared those two group. Results : 1. There was no significant difference at the treatment period and the number of treatment times in comparing two groups. 2. The number of treatment times for good effect is that : Dong-si took $1.57{\pm}0.85$ times and General acupuncture therapy took $2.15{\pm}0.96$ times. And we have found that the effect of Dong-si acupuncture therapy is faster than the other.

In order to observe hydrological characteristics in the Gulf of Yoeng-il, measurements of water temperature have been carried out from February to August 1983, and from August 1985 to December 1986. Surface water temperatures are closely linked to air temperature and solar-radiation for all littoral stations. Seasonal and annual variations of all horizontal stations are very similar to one another. Vertical variations of water temperatures for the stations located along the central-line of the Gulf are characteristic (and observed) as thermoclines and thermal stratification in the hottest summer-time (August). It is interesting to note that water column temperature of July and September are rather warmer than August, on account of a cold water mass coming from NE direction. For example, surface temperature in June 1982 was above 19℃, but the water below a depth of about 30m drastically drops to 4℃. It is indicative of invasion of water mass from cold current or deep sea.

Since the introduction of Mathematica in 1988, it has been succesfully utilized in various research fileds including mathematics and physics. In this study, we use the numerical and graphical power of Mathematica to analyze the voice traffic and the video traffic mixed with voice traffic under the B-ISDN environments. We adapt the fluid flow approximation as the basis of traffic modelling. The individual video source is modelled as a 3-state continuous time Markov chain. We present both numerical examples and Mathematica procedures in order to demonstrate the convenience of Mathematica as well as the validity of the model.

This study was carried out to improve the organic farming system about crop cultivation, compost production and application, plant diseases & pest control, weed control and marketing system of organic farming products to the case study in Chungnam Hongdong area. Agricultural technologies concerning pest & diseases control, weed control and compost production are not established due to lacks of systemized researches by the agricultural scientist, and agricultural machines profitable to this works had not developed yet. In cropping system, reasonable crop rotation had not conducted. The related cultivation of vegetables on the same ground for a long time cause a various plant disease easily. So crop rotation is a reasonable method about soil nutrient utility and soil disease control. It is a good method that introduce the barley and wheat in this field crop system. Those crop have a long root, so can use the other nutrient against the vegetable. In organic farming products, the safety and quality of products by the National Agricultural Products Inspection Center had not inspected except rice, lettus and apple. Inspection is needed for the development of organic farming and mutual confidence between producer and consumer, because the mutual confidence is a major thing to sustain the organic farming. In products marketing, it is more need for the information of organic farming products. Nowaday most products are marketed in Seoul region, but it is not a good method. To search the consumer in near region is a good method for decrease the cost of conveyance and maintain the quality of products. The varieties of distribution structure of organic farming products are required. The products are sold to department store in large city and the prices are about 30% higher than normal products. But when those are supplied in near region, the prices of those are similar to normal products. Direct transactions in near regions is a good method for decrease the cost of conveyance and strength the mutual confidence between producer and consumer.

본 논문은 두 편으로 구성된 스마트 능동 레이어(smart active layer, SAL) 센서 개발에 관한 첫 번째 논문으로, 구조 내에 발생하는 균열 및 손상에 의한 탄성과 검출을 위한 SAL 센서의 이론 및 개념을 연구하였다. 본 SAL 센서의 개발을 위해, 첫째, 탄성파의 기본 이론을 고찰하였고, 둘째, 이론적 토대 위에 단일 압전 disc의 유한요소해석법(finite element analysis, FEA)을 이용하여 탄성파 검출 센서로서의 가능성을 검증하였고, 셋째, 몇 종류의 압전 disc 센서와 상용 음향방출(acoustic emission, AE) 센서를 연필심 파괴시험을 통해 상호 성능을 비교하여 실험적으로 그 가능성을 확인하였다. 또한 수개의 센서를 일정한 거리로 분포시켜서 구조물 결함의 효과적 검출 및 위치 표정이 가능한 스마트능동레이어 센서의 개념연구를 수행하였다. This paper is the first part of the study on the development of a smart active layer (SAL) sensor, which consists of two parts. In this first part, the theory and concept of the SAL sensor is investigated, which is designed for the detection of elastic waves caused by internal cracks and damages in structures. For the development SAL sensor, (ⅰ) the basic theory of elastic waves was studied, (ⅱ) the feasible study of the SAL as an elastic waves detection sensor using the finite element analysis (FEA) with respect to a piczoceramic disc was performed. (ⅲ) the comparison of performances between some piczoceramic sensors and a commercial acoustic emission (AE) sensor was accomplished to ensure the applicability by the experimental means, such as a pencil lead break test. Also, the conceptional study for the SAL sensor, which can be utilized for the effective detection and locating of defects by the arrangement of regularly distributed sensors, was discussed.

The growth in popularity of sports over the past several decades has brought increased attention from government and new possibilities for sport management. This study considered the relationship between sports and politics, and the effects that demographic characteristics have on opinion of this relationship. The research provided and extensive discussion of the theoretical and historical connections between sports and politics. survey analysis were conducted to test whether Korean students at three major colleges in Pusan, Korea, saw the connections between sports and politics, what factors determined their views on these relationships, and if their view affected their opinions on appropriate sports management policy. The study found that there was significant support for the claim that sports and politics were related. It showed that the people who were most likely to see the connections were well-educated, less active on a daily basis in either sports or politics, desirous of having integrated government involvement in sport management, older, socially aware, politically liberal in their desire that government meet citizens' needs, involved in sports for physical fitness or entertainment, and male.

This paper is concerned with the dynamic characteristics of buildings, especially with the measurement of the natural frequencies(natural periods). The vibration measurement methods employed for field measurement and presents reliable methods of accessing natural period from ambient vibration tests. Data from measurement on 16 reinforced concrete buildings in Seoul City and Seoul national university of technology are given. 16 Low-rise Reinforced concrete buildings are measured for ambient vibration to obtain the natural frequency. The natural periods obtained by ambient vibration measurements are compared with those of forecast model suggested by standards and foreign researchers.

Although porous concrete is recently used as a pavement at a parking lot, a public squre and a bicycle road, we use without enough examining. Most the maintenance of quality for porous concrete is only dealt with strength and color tone. Also, there is not et enough fundamental data about dynamical properties for strength, rate of void and water permeability. Even when it is applied to at the scene, it is been a matter. Accordingly in this study analyzed influences through the dynamical properties, combination, and time to vibration. After the analyzation, they investigated peculiar dynamics which are strength of porous concrete, rate of void, and water permeability follow the rate of increase on an admixture making pozzolan reaction. This is purpose to improve capacity of the sidewalk permeable concrete and development of the economical technique for pavement.
