탈취제로 이용되고 있는 지렁이 분변토로 부터 황화수소를 제거하는 황산화 세균 CP-5를 분리하였다. 이 균주는 운동성이 없고 Gram 음성인 단간균 이었으며, cytochrome oxidase와 catalase test에 양성 반응을 보였다. CP-5 균주는 환원형 황합물을 기질로 하는 배지에서 독립영양적인 생장이 가능하였다. 이 균주는 thiosulfate 에서 tetrathionate를 중간생성물로 하여 최종적으로 sulfate로 산화하고, elemental sulfur를 일단 thiosulfate로 산화한 후, sulfate까지 재산화하는 것으로 사료되었다. 독립영양 배지에 yeast extract 를 첨가하면 균의 생장이 촉진되었다. CP-5 균주 현탁액에 H₂S를 2vvm의 유속으로 주입하면 140ppm까지는 거의 완전하게 제거 가능하였다. 본 연구결과로부터 CP-5 균주는 분변토에서 황화수소를 제거하는 대표적인 탈취균주이며, 황화수소 제거를 위한 생물학적 탈취 공정에 활용 가능하다는 것을 알 수 있었다. A new sulfur-oxidizing bacterium which was capable of degrading hydrogen sulfide was isolated from earthworm casts using deodorant materials. The cell of isolate CP-5 was short rod, gram negative and non-motile, the activities of cytochrome oxidase and catalase were positive. The isolate could autotrophically grow in the basal mineral medium supplemented the reduced sulfur compounds such as thiosulfate and elemental sulfur. This bacterium could oxidize thiosulfate and elemental sulfur to sulfate, and the metabolic intermediates were considered as tetrathionate and thiosulfate, respectively. The removal of hydrogen sulfide by the isolate CP-5 was confirmed, and the CP-5 was regarded as one of microorganisms responsible for degradation of hydrogen sulfide in earthworm casts. The isolate CP-5 can be applied to biodeodorization systems for the improvement of removal efficiency of hydrogen sulfide.

This paper presents a design method of fuzzy logic controller(FLC). In the proposed method, the parameters of FLC are determined by using Genetic Algorithms(GAs), which is an optimizing algorithm. Two types of FLC are considered. One is FLC with control rules whose fuzzy variables are all assigned by linguistic quantity. The other is FLC with control rules which are inferenced with simplified reasoning. For each FLC, the method of applying the GAs to determine the parameters of the FLC is proposed. By the simulation study for four systems with different characteristic, the usefulness of the proposed design scheme is discussed.

This study aims to find a solution promoting sports tourism as the affective plan for tour industry in Mokpo area. This study will define the necessity of sports tourism development and provide the solutive of sports tourism development in Mokpo area by researching and analyzing sports tourism environment and opinons. For the examination objects, sports tourists who visited Mokpo area (Mokpo, Sinan, Muan, Yeongam, Haenam), sports tourism industry workers, politicians for tourism policy, college students, local citizens are referred to, and the samples of examinations objects is drawn out by Stratified Cluster Samplig and Convenient Sampling. Total numbers of samples are 776, but final available samples are 738 excepted 36 who answered thoughtlessly. The question sheet for this for this study compares previous studies of Gibson(1988), Danaher et, al, (1996) and Yoon, Yee-Joong. It is composed to social-population property, tourism experience, divelopment possibility, appraisement for tourism, golf course constrution, marine sports development, etc The way of statistics in this study is technical statistics to examine the general property and cognition of examination objects, T-test and Anova are used for comparing analysis according to population statictic property. The conclusions from the study are as follows : First, pulblic officers, workers of tourism, and the inhabitants have very low level of conscioysness about sports tourism. So the condition of sports, tourism is very poor. Especially the fact that the policy makers have very low level of consciousness about sports tourism is the biggest problem in developing Mokpo area as a modern and international tourism center. Second, the condition and environment of tourism Mokpo area is very poor because of the difficulty of approach. the lack of facilities, the lack of advertisement, and so on. But there are various sports tourism resources such as beautiful tour course of the land and the sea, deaches of Sinan-Keun, places for fishing, diving points for construction of golf course in Haenam and Youngam. Third, Mokpo area has bright prospect in not only the domestic tourism for the tourists of seoul and large cities but also the international tourism for the tourists of Japan, China, and South-east Asia. If the SOC business in Mokpo area are West-coast Highway, Muan International Airport, Mokpo harbor, the removal of provincial office, the construction of double train track, and so on. In addition to this, Mokpo area in the starting point of the southern seashore touting belt which is carried by the government. So Mokpo area has good condition to construct tourism infrastructure and has big potentiality to be the center of sports tourism of Korea. Fourth, it is needed to make and pursue the policy which makes Mokpo area as the center of golf tour, finshing tour and diving tour. The way to do this is like this hold various seminars and debating societies to change the consciousness about sports tourism, and construct golf courses, beaches, associated with sports tourism, it is mecessary to held national sports games, invent sports programs and sports tourism packages connected with local festival, make internet site to advertise sports tourism, and plan political policy to develop the speciality of sports tourism.

□Acceleration control scheme is known to be useful for the robust control of motors. In this paper, a new acceleration control scheme for position control of DC servo motor is proposed. In the proposed scheme, the acceleration of DC servo motor is directly controlled by a FLC(Fuzzy Logic Controller).The robustness of conventional acceleration control system can be improved by introducing FLC which is useful for controlling processes with uncertainties. The robustness of the proposed control scheme to the parameter variation and load disturbance is shown through a simulation study.

To evaluate the degree of bone mineral density according to physical activity, lifestyle in pre- and postmenopausal women. The subjects were 951 premenopausal and 1,167 postmenopausal women who have examined in health promotion center of Yeungnam University Hospital in Daegu city from January, 1999 to Januaty, 2001. The test for bone mineral density. The physical activity and life style were evaluated by questionaire through interview. The results were summarized as follow. 1) The prevalence rates of reduced bone mineral density and osteoporosis in premenopausal women were 23.8% and 1.6%, respectively. However, these values were increased to 46.1% and 28.1% in postmenopausal women. 2) The regular exercise was revealed to have preventive effect for osteoporosis in pre- and postmenopausal women. Among the types of exercise, the most effective exercise was bowling and moderately effective exercise was swimming on prevention of osteoporosis, however, bare hand physical exercise was not significant effect on bone mineral density. 3) The risk for reducing bone mineral density was decreased in women who have higher educational background and income in pre- and postmenopausal. The bone mineral density was highest in white color worker and lowest in blue color worker. 4) The premenopausal women who favor meat were revealed higher bone mineral density than the women who favor vegetable. The women who have drunk none or small amount of alcohol were revealed increased bone mineral density and smoking was a risk factor for osteoporosis. These results suggested that to prevent osteoporosis, the systemized program for promoting anti-osteoporotic factor have to be developed and apply from the thirties whom have maximal bone mineral density.

Input shaping is widely accepted to be a useful tool for removing residual vibration in cranes. The UMZV(unity magnitude zero vibration) input shaper is often employed for cranes driven by on-off type motors. However, the UMZV input shaper makes the cranes move slightly further than expected from the original command while it can remove the residual vibration out of the cranes. This paper deals with a method of input shaping scheme which can compensate the position inaccuracy as well as remove the residual vibration of cranes. The proposed method is illustrated through a numerical simulation.

국내에서 채집한 진드기의 라임병 및 ehrlichiosis원인체 보균 상태를 조사하기 위하여 총 516마리 (Ixodes spp. 22마리, Haemaphysalis spp. 494마리)의 ixodid 진드기를 봄과 가을에 걸쳐 강원도 고산지대 일원에서 채집하였다. 수집한 진드기에서 DNA를 추출 ·정제한 후 추출한 DNA를 template로 이용하여 , Borrelia burgdorferi sensu lato 및 Ehrlichia spp.에 특이하게 반응하도록 제작한 primer를 이용한 중합효소연쇄반응 (polymerase chain reaction, PCR)을 실시하였으며, 이 결과를 oligonucleotide probe를 사용한 southern blotting을 통하여 다시 확인하였다. 총 516마리의 진드기중 B.garinii sensu lato DNA 양성 인 진드기는 68(13.2%)마리 (B. burgdorferi sensu stricto,2; B. afzelii,1; B. garinii,33; B.tanukii,8; B.turdae, 4)로 나타났으며 이 중 37 (7.2%)마리의 진드기 는 southern blot analysis에서도 양성으로 확인되었다. 또한 101 (19.2%)마리의 진드기가 Ehrlichia spp.에 대한 PCR에서 양성 이었으나, 이들 중 25 (4.8%)마리 만이 southern blot analysis에서 양성으로 확인되었다. 그러나 사람의 병인체로 추정 되는 human granulocytic ehrlichiosis (HGE) agent DNA를 보균한 진드기는 확인되지 않았다. 한편 라임병균과 ehrlichiosis원인체를 동시에 보균한 것으로 밝혀진 진드기가 3마리에서 (0.6%)확인되어,국내에서도 진드기 교상시 이들 두 가지 열성질환이 동시에 감염될 가능성이 있는 것으로 사료됨으로 진드기 매개성 열성질환에 대한 적절한 진단법 등을 보다 체계적으로 연구하여야 할 것으로 판단된다. To investigate the distribution of Borrelia Burgdorferi and human granulocytic ehrlichiosis(HGE) agent in ticks, adult ixodid ticks of Ixodes spp. and Haemaphysalis spp. were collected from the high mountain areas of Kangwon Province. Using DNAs extracted and purified in the collected ticks, polymerase chain reaction (PCR) was performed to amplify the specific nucleotide sequences of both agents. Of the 516 ticks, a total of 68 (13.2%) ticks was positive for Borrelia burgdorferi sensu lato with PCR analysis (2 for B. burgdorferi sensu stricto; 1 for B. afzelii; 33 for B. garinii; 8 for B.tanukii; 4 for B. turdae). However a little more than half of PCR-positive ticks (37/68) was found to be positive in the southern blot analysis with Bl6S oligonucleotide probe. One hundred and one (19.2%) ticks were positive for Ehrlichia spp. in PCR, and a quarter of them (25/101) was positive in southern blot with E16S oligonucleotide probe. But none of them was found to be the DNA of HGE agent. And 0.6% (3/516) ticks were positive for both of B. burgdorferi sensu lato and Ehrlichia spp. These findings might implicate the possibility of the outbreak of lyme borreliosis and ehrlichiosis in Korea, and more extensive studies may be need for the diagnosis of multiple tick-borne diseases.
