The systematization of construction information is required over whole life cycle of facilities to improve productivity of construction industry. BIM has been actively suggested as one of alternatives. However, it may be currently concentrated on the large-scale facilities while the small and medium-scale facilities based on BIM are slightly treated in indifference. This study has been performed to set up information management system based on BIM considering characteristics of small and medium-scale facilities. PLIB of ISO and construction information classification system of by MLTM in Korea are used in this study.

This research was performed to test the effects of oleic acid for the management of greenhouse whiteflies and tobacco whiteflies. Tobacco whiteflies, especially, are the vectors of tomato yellow leaf curl virus on tomato plants. Whiteflies are not only the vectors of various viruses but also the major insect pests that cause direct damages through sucking and induce sooty mold with their sweet dew on tomato plants. There are many eco-friendly management measures including the use of yellow sticky trap and natural enemies such as Eretmocerus eremicus and Amblyseius swirskii. However, these management measures have difficulties to implement in the greenhouse. Therefore, in this research, oleic acid was tested for its effect on the management of whiteflies at various concentrations of 1,000ppm, 2,000ppm, or 4,000ppm. As a result, treatments of 1,000ppm, 2,000ppm and 4,000ppm oleic acid showed the control value of 70%, 76% and 84%, respectively. In another test, treatments of 2,000ppm oleic acid, and control treatment of 1,5000ppm neem oil and 50ppm dinotefuran showed the control value of 82%, 75%, and 75%, respectively. Cost for one application of oleic acid and neem oil for 10a area would be 3,180 Won and 20,150 Won, respectively. As a result, it was assumed that the use of oleic acid would be a appropriate management measure.

The present study was carried out to investigate the in vivo single-dose acute toxicity of Leuconostoc citreum GR1 (Leuc. citreum GR1), a lactic acid bacteria isolated from kimchi, in ICR male and female mice. The test article was orally administered once to both sexes of mice. The mortalities, clinical findings, autopsy findings, and body weight changes were monitored daily for two weeks. The male and female mice were gavaged with Leuc. kimchi GR1 of four doses (625, 1,250. 2,500 and 5,000 mg/kg). The oral LD50 of Leuc. citreum GR1 was considered higher than 5,000 mg/kg. No significant changes in the general conditions, body weights, clinical signs and presence of gross lesions were observed in both sexes of mice to whom Leuc. citreum GR1 was administered orally. The results indicated that the 5,000 mg/kg dose of Leuc. citreum GR1 showed no adverse effect.

The in vivo single-dose acute toxicity of Lactobacillus plantarum AF1, a lactic acid bacterium isolated from kimchi, in ICR male and female mice was investigated. The test article was intraperitoneally or orally administered once to both sexes of mice. The motalites, clinical findings, autopsy findings, and body weight changes were monitored daily for 14 days. In the oral acute toxicity test, the male and female mice were gavaged with four doses (5.0, 2.5, 1.25 and 0.625 g/kg) of Lb. plantarum AF1. The oral LD50 of the Lb. plantarum AF1 was considered higher than 5.0 g/kg. In the intraperitoneal acute toxicity test, mice were injected intraperitoneally with dosages of 0.7, 0.9, 1.1, 1.3, 1.5, 1.7, 1.9, 2.1, 2.3 and 2.5 g/kg. The intraperitoneal 50% lethal dose (LD50) of the Lb. plantarum AF1 was >2.5 g/kg in the male and female mice. No significant changes in the general conditions, body weights, clinical signs, and gross lesions were observed in both sexes of mice to which Lb. plantarum AF1 was administered intraperitoneally or orally. The results suggest that the no-adverse-effect level of Lb. plantarum AF1 is estimated to be more than 5.0 g/kg in the oral route and 2.5 g/kg in the intraperitoneal route.

신경리포푸신증(NCLs)은 신경퇴행 축적 질환으로 뇌에 자기형광물질을 포함한 다양한 물질의 축적이 야기되어 발생하며, 노던에필렙시를 제외한 모든 신경포푸신증은 리소즘 축적 질환으로 분류된다. 이러한 신경리포푸신증은 전세계적으로 12,500명 중 1명에게 발생되는 높은 발병 빈도를 나타내며, 그 발병 시기에 따라 영아형, 영유아형, 유년형, 그리고 성인형과 같이 분류된다. 신경리포푸신증이 유발하는 의학적 증상로는 시각 손실, 발작, 간질, 진행성 정신지체

This study performed in order to evaluate the effects of pipe materials on corrosion and bacteria regrowth using a laboratory scale batch test. Two varieties of feed water with different microbial conditions were selected: tap water, surface river water (Han River water), and five pipe materials; carbon steel, copper, galvanized iron, stainless steel, and PVC. Carbon steel and galvanized iron pipes showed higher corrosion rates than other materials. In terms of attached bacterial growth, pipes with PVC and stainless steel showed higher bacteria concentration compared to other materials. Pseudomonas vesicularis was the predominant bacteria found on biofilm. The behavior of bacterial growth in the pipes was observed using a scanning electron microscope.

갈수량은 수자원의 개발 및 관리에 매우 중요한 인자중의 하나이다. 신뢰성 높은 갈수량을 측정하기 위해 한국수자원공사는 2000년도에 용담댐 시험유역에 5피트 규격의 파샬플륨을 설치하였다. 파샬플륨은 유량측정을 하기 위해 독특한 모양을 가지고 있으며, 부정확한 유량관측을 유발하는 퇴사문제를 거의 해결한 시설물이다. 본 연구에서는 3차원 CFD (Computational Fluid Dynamics) 모형으로 5가지 수위에 대해서 완전월류(free flow)
