The present study, black soldier flies (Hermetia illucens) fermented using lactic acid bacteria were powdered without defatting and added to 3% or 5% to make pig feed. Weaning piglets were fed 3% (T3) or 5% (T5) feed powdered with Hermetia illucens for 5 months and the efficacy of the feed was investigated. The results of measuring body weight gain over 5 months after adding 3% (T3) or 5% (T5) of Hermetia illucens powder to the feed of weaned piglets showed significant weight gain in the T5 group compared to the control group. The added feed to Hermetia illucens powder did not show toxicity, and analysis of its effect on blood properties showed that white blood cell levels tended to increase in the T3 or T5 group compared to the control group.The only increase in white blood cell count was a change within the normal range. As a result of analyzing the effect of the level of addition of Hermetia illucens powder on feces, the effect of liquid reduction showed excellent results in the T3 treatment group and maintained the best form of feces. In this study, the thawing loss in the control group was 6.66%, and the T3 group with added powder to Hermetia illucens showed a significant decrease of 5.03%, and the T5 group also showed a decrease of 5.61%. Therefore, it was demonstrated that additive feed for Hermetia illucens reduced thawing loss, affected the water holding capacity of meat, and played an important role in maintaining the taste of meat. Moreover, the results of carcass grade showed a tendency for one grade to increase in the T3 and T5 groups fed additive feed to Hermetia illucens compared to the control group. In conclusion, the results of this study suggest that feed supplemented with Hermetia illucens is effective in influencing the weight gain of pigs, reducing the liquid content of feces, and increasing carcass grade.

This study aimed to develop the in vitro method using domestic commercial diets to estimate nutrient digestibility in dogs. The existing in vitro method were tested and compared with literature data to develop new in vitro method. The development of in vitro method progressed as follows: modification of pepsin solution to an activated form and supplementation with 1% lipase. All the in vitro method progressed to 4 hours of stomach simulation and 2 hours of small intestine simulation. In vivo digestibility was measured using the same diets as beagle dogs. The supplementation of lipase methods showed significantly improved (p < 0.05) DM, OM, and EE than the existing and modified pepsin solution methods. The correlation between in vitro and in vivo data in DM, OM, and EE digestibility was high (r2 = 0.889, 0.907, and 0.721, respectively), and the correlation between in vitro and in vivo data in CP and GE digestibility was medium (r2 = 0.681 and 0.536, respectively). The current in vitro method is similar to in vivo digestibility and helps potentially predict digestibility for dogs. In conclusion, this developed in vitro method suggests that it can help estimate the nutrient digestibility of dogs' diets without in vivo experiments.

연구는 참외 재배 지에서 흰가루병, 담배가루이 및 두점박이응애가 동시에 발생하였을 때 45, 40, 35°C (대조구)의 온도에서 측창으로 환기 처리 시, 온실 내 온 ․ 습도의 변화, 병충해 발생과 잎말림, 그리고 개화조절에 미 치는 효과를 검토하였다. 3월 3일 ‘히든파워’ 대목에 접붙여진 ‘알찬꿀’ 참외를 40cm 간격으로 격리상에 심었고, 위 에 언급한 병해충이 모든 처리구에서 발생한 6월 18일부터 7월 13일까지 처리하였다. 온실의 온도는 맑은 날에는 설정 온도 지점까지 증가되었고, 45°C 환기 처리에서 고온 고습이 약 9시간 동안 유지되었다. 주간 최고 기온과 최 저 상대습도 차이는 45°C 환기 처리에서 가장 높았다. 환기 처리 11일 후에는 흰가루병과 두점박이응애 피해가 45°C 환기 처리에서 거의 회복되었지만 40°C와 35°C에서는 그렇지 않았다. 처리 14일 후, 담배가루이와 두점박이 응애 밀도는 45°C에서 유의하게 감소하였으나 흰가루병 증상은 유의하게 감소하지는 않았다. 잎말림은 고온에서 유발되었으나 45°C에서도 심하지 않았다. 처리 26일 후, 새로 나온 줄기의 15 마디의 개화수를 조사한 결과, 45°C에 서 암꽃이 전혀 나오지 않았고 수꽃은 1.2개로 나타났다. 이상의 결과는, 고온기에 45°C의 고온에서 2－3주간 환기 처리는 온실 내부의 고온 고습을 유도하여 흰가루병, 담배가루이, 두점박이응애를 통제하고, 개화를 억제하여 참외 의 영양 생장을 회복할 수 있는 방법으로 사료되었다.

Lentinula edodes is known by oak mushroom. It has been favored as delicious and nutritious food and the low-calorie food with a high nutritional value. It is also functional food since it contains a material well-known for its medicinal benefits. Since the growth and quality of oak mushrooms are sensitively affected by environmental conditions, an adequate environmental control is very essential to improve the yield and quality under protected cultivation. The main objectives of the study were to investigate cultural characteristics of mycelial growth and in vitro fruiting of Lentinula edodes. The optimum culture media for mycelial growth of L. edodes were PDA and MYA. Similarly, optimum temperature was 25℃. Malt extract(2%) and yeast extract(0.2%) were optimum carbon and nitrogen sources. Optimal culture period was 110~120 days in sawdust medium. Among different five log types, highest mycelial growth and fruiting productivity were observed in Quercus variabilis sawdust(20.9%).

Field research was undertaken for recovering mosquito larval mermithid parasite, Romanomermis species in rice fields in 54 different areas in period of May through October, 2009. Of 54 area rice fields surveyed, Romanomermis sp. recoveries were made from 4 areas. 32 Anopheles mosquito larvae, malaria disease vector were infected and died from samples collected in Pochon area, and a total of 10 Culex mosquito larvae, house frequenting mosquito were infected to death in 3 different areas, Gimpo, Sangju and Gurae, respectively. On the basis of positive natural infection record, an intensive host-parasite occurrences and/or population study was surveyed in foci area of Pochon in small pond (P) and Rice paddies (A and B) during 5 months till end of October. The natural mermithid infection was continuously occurred from June through October in weekly samples, however the rate of infection was appeared higher in June-July, thereafter the rate gradually decreased in progress of the season. The highest natural infection rate was observed from the Pond 9.1% followed by Rice paddy "A" 5.2%, Rice paddy "B" 2.4%, respectively. Including 2 other Rice paddies "C" and "D", a total mosquito larvae collected was 3,270, an overall average natural infection rate was recorded as 3.7% (121 Anopheles mosquito larvae infected).

The purpose of this study was to investigate the distribution of trig˗ ger points(TrPs) on athletes with various sporting background. To achieve the purpose, a study was carried out through a survey from 180 athletes involved in 6 selected sports at Yong-In University. Selected sports included Judo, Taekwondo, Kendo, Ssi-reum(Korean traditional wrestling), Boxing, and Golf. An interview type survey and physical examination were conducted with each thirty athletes from each of the selected sports groups. Technical statistic(SPSS 15.0) was used to analyze the distribution of TrPs on these athletes. The most common TrPs observed in muscles of Trapezius, Quadratus Lumborum, Quadriceps in Judo. In Taekwondo, it was on the trapez˗ ius and triceps surae. Kendo athletes had TrPs at sites of trapezius, brachioradialis and triceps surae. Ssirem athletes were found to have TrPs on trapezius, deltoid and quadrates lumborum. In boxers, TrPs appearing at trapezius and brachioradialis were observed. Finally, Golf players were seen to have TrPs at trapezius, quadrates lumbo˗ rum and brachioradialis. Hence, the analysis shows that there are significant differences of the distribution of TrPs according to the different sport items of the athlete.
