The attraction activity of the natural baits for sea eels(Astroconger myriaster) was surveyed by using fishing traps in the 3 different fishing ground of southern coastal waters of Korea. Twenty four different baits were experimented and weight for each bait was 50g, the optimal minimum weight owing to our preliminary test. Among the above 24 baits, anchovy(Engraulis japonica), sardine(Sardinops melanosticta), or marine worms(Neanthes japonica)were most effective. In case of sardine bait, the body showed higher attraction activity than the head or viscera and the builded juice of anchovy or sardine showed higher attraction activity than spoiled one.

Two kinds of simple and interesterfying mixed rapeseed oil were prepared according to add 30%, 50% and 70% of coconut and palm oil, then the physicochemical propecties such as the tedency of oxidation, foaming activity were Investigated. The initial AV and POV of interesterifyung mixed rape-seed oils were higher than those of simple mixed oils, but the tendencies of oxidation were similar. The intial value of IV interesterfied rapeseed oils was added in simple mixed rapeseed oil, Induction period were increased about 2.4~4 times. Induction period of intereterifyng mixed oils added palm ell increased about 2~3.2 times. While the foaming Buantity of interesterifing mixed rapeseed oils with palm oil were lower about 28~40% than those of the simple mixed rapeseed oils.

This experiment was conducted to determine the most effective type of Bight·trap for pine catepillar moths (Dendrolimus spectabilis B.) and to investigate the environmental factors affecting the attractiveness of the moths.. The various types of light traps made used of: black light, white light, fluorescent light, yellow light, and red light and the environmental factors considered were rainfall, wind velocity and collecting time. All the traps were operated from 8 in the evening to midnight. The results obtained are summarized as follows; The most effective attraction of moths ($62\%$ of total number attracted) was observed with blacklight-lamp and the most abundant attraction of the moths was found from 8 to 10 in the evening. Attractiveness in terms of sex ratio attracted from 8 to 10 in the evening was found to the .approximately 7 female to 1 male, Environmental factors considered were found to have no influences in attractiveness of the moths in this experiment.

This study was carried out to investigate the characteristics of goat and cow milk yogurts containing high-exopolysaccharide fermented by Streptoccous thermophilus LFG isolated from kefir. The pH of cow milk yogurt was higher than that of goat milk yogurt. The contents of lactic acid was greater in goat milk yogurt (743.9-1043.8 mg/100 g) than in cow milk yogurt (441.6-709.9 mg/100 g). The numbers of survival lactic acid bacteria were the greatest in goat milk yogurt fermented by Str. thermophilus LFG. Viscosity was greater in cow and goat milk yogurts cultured by Str. thermophilus LFG than in yogurts by Str. thermophilus TH3. Syneresis of yogurt fermented by Str. thermophilus LFG was 9.6-16.1% and 28.2-31.8% in yogurt fermented by Str. thermophilus TH3 after 10 d storage at $4^{\circ}C$. Flavor compounds identified from goat milk were acetone, ethylbutanoate, ethyl-3-methylbutyrate, ethyl-2-butenoate and ethylhexanoate, and those from cow milk were ethylbutanoate, acetone, 2-heptanone and acetoin. Flavor compounds detected from goat milk and cow milk yogurts were acetic acid, butanoic acid, butanol, diethylcarbinol, acetone, diacetyl, decane, 2-methyl-3-pentanone, hexanal, 2-heptanone, acetoin, benzaldehyde, dimethyldisulfide, and dimethyltrisulfide. In sensory evaluation, overall preference and texture values were higher in goat milk yogurt fermented by Str. thermophilus LFG than in cow milk yogurts and the yogurt fermented by mixed culture resulted in the highest score.

The pinning method is the traditional method to produce strawberry transplants. But, cultivating the pinning transplant is a labor-intensive operation and needs a long labor period. The cutting method has been considered as an effective alternative to the pinning method, due to the relatively short labor period and works time. This study was conducted to investigate the labor period, work time, and growth between pinning and cutting methods for strawberry transplants. The 'Maehyang' strawberry was cultivated at each pinning and cutting strawberry greenhouses. The time for special works on pinning method (pinning work, elimination of mother plant, and division of daughter plant), and cutting method (cutting collection, pretreatment before storage, and cutting work) were measured. The pinning method needed 6 tasks (planting of mother plant, maintaining of mother plant, pinning work, maintaining of daughter plant, elimination of mother plant, and division of daughter plant) for 158 days, and cutting method needed 4 tasks (collection and storage of cutting, cutting work, misting, and maintaining of transplants) for 113 days to cultivate transplants for fruit. And pinning method needed more work time than the cutting method. There was no significant difference between the growth of pinning and cutting transplants. These results showed that the cutting method saved more labor period, work time than pinning during the nursery period without losing transplant quality.

To enhance the control efficacy against cockroaches in dwelling space, repellent ("Push") was set down on one comer and a poison bait including attractant ("Pull") was on the opposite side. And we tested the control efficacy of Push-Pull strategy by behavior-stimuli of cockroaches. In a mini-field test, German cockroach males primarily chose shelters nearest to the attractant-treated surfaces and farthest from the repellent-treated surfaces. The consumption of food or bait was also highest from food nearest to the preferred shelters by push-pull effect. We evaluated the push-pull insecticidal efficacies of five essential oils belong to Citrus plant, namely, grapefruit, lemon, lime, orange, and petitgrain. The combined push-pull treatments appeared to be faster and higher insecticidal effects than single (pull) treatment, and the repellent efficacy of Citrus oils was in the order of grapefruit > lemon > lime > orange > petitgrain. Therefore, we propose the effective control of the german cockroach using Citrus oils as repellents and push-pull method into a limited area.

연구에서는 HEC-RAS 모형을 이용한 부등류 모의를 통하여 댐 방류수의 유하시간을 산정하고 이를 실시간 댐 방류수의 봉부자 추적실험에서 산정된 유하시간과 비교검증 하였다. 대상구간은 충주댐지점부터 여주대교까지 총 63.6km에 이르는 남한강 본류 구간으로 164개 단면으로 나누어 부등류 모의를 하였다. 유하시간 실험은 센서가 내장된 봉부자를 최초 시작지점에 투척하여 주요 교량에서 봉부자를 관측하여 최초 투척된 시간으로부터 교량을 통과하는 시간을 관측하는 방법을 사용하였다. HEC-RAS 부등류 모의 결과 2007년 8월 7일 방류량(680CMS)의 유하시간은 약 13시간으로 산정되었고 봉부자 추적자 실측자료를 통한 유하시간은 11.5시간으로 산정되어 실측치가 모의치보다 유하시간이 빠른 것으로 나타났다. 구간별로 살펴보면 HEC-RAS 모형의 모의결과는 수행교에서 충주조정지는 1.4시간 느리게, 목계교에서 남한강교는 1.0시간 빠르게 모의되었으나 나머지 구간에서는 실측치와 대체로 일치하였다. 본 연구는 유하시간 실험 구간 및 구간과 동일한 조건으로 모의함으로서 모형을 보정하기 위한 실측 유하시간 자료를 확보하였으며, 이러한 실측자료를 토대로 보정된 모형의 매개변수를 이용함으로서 대상 수계의 방류량별 유하시간을 산정하는데 정확성을 제고하고 홍수기 댐 운영 및 홍수예경보에 반영될 수 있을 것으로 기대된다.
