Objectives : There is a increasing need to recruit and retain more psychiatrists who can plan and implement organized programs to work with chronic mentally ill patients in community settings. The aim of study is to discover what training is currently in place to prepare psychiatrist for work in "community" or "public" settings. Methods : Survey questionnaires were mailed to 85 residency training directors and 10 leaders of community mental health in 2005. Response rate was 75%. Results : Academic seminar about community mental health were not administered to residents in 63% of training hospitals. Forty one out of 64 training hospitals had community mental health rotation programs, Community mental health center (50%) and day hospital (36%) were the most common type of programs. Few general hospital had affiliation with community mental health programs. The amount of time for clinical rotation varied from less than three months part time to 6 months fulltime, with most frequent form of one day per week for three month in second or third year of psychiatry residents. Conclusion : Further steps are needed to improve residency training curricula and to encourage well qualified psychiatrist to choose careers in community psychiatry.

This study was conducted to examine aspects of health and safety education and demand level of safety education in construction job sites in order to provide direction of safety education development. The subjects of this study were 566 workers who were working in construction job sites located in Daegu City and Kyungbuk Province. Data were collected from June 1, 2002 to August 30, 2002. The results of this study can be summarized as follows. 1. According to safety education by experience methods, the proportion of education by lecture was highest (90.6%). The proportion of education by field practice was 13.1%. 2. Among the education methods which they thought as the most desirable method, the proportion of audio-visual education was 39.4% and the proportion of education by experience was 37.5%. Those who had more monthly income and higher education level preferred audio-visual education, while those who were younger and less educated preferred education by experience. 3. In the case of the contents of the safety education which they thought as the most important one, the proportion of enhancement of safety awareness and education of risk factors was highest (24.7%). The groups of older workers, having longer working period, and belonging to higher education level preferred these contents. 4. According to the factors which were most important to increase effectiveness of the safety education were workers' voluntary participation (27.7%), 40 to 49 years old (27.7%), and monthly income of one million, five hundred thousand won to one million, nine hundred ninety thousand won (32.0%). The proportions of lower educated workers and working as daily workers were also high. 5. The variable which most influenced the safety education was age. The safety awareness of construction job sites was the second highest influential variable. From above results, it is clear that the workers' participation in the safety education was low since most of the safety educations were formal education by lecture. Although they participated in the education, the education was also not effective because they compulsorily participated in it. Therefore, it can be concluded that effective alternative policies must be formulated.

Purpose : The study was aimed to detect the induction of apoptosis, cell cycle arrest and calcified nodule formation after irradiation on primarily cultured osteoblasts. Materials and Methods : Using rat calvarial osteoblasts, the effects of irradiation on apoptosis, cell cycle arrest, and calcified nodule formation were studied. The single irradiation of 10 and 20 Gy was done with 5.38 Gy/min dose rate using the 137Cs cell irradiator at 4th and 14th day of culture. Apoptosis induction and cell cycle arrest were assayed by the flowcytomtry at 1,2,3, and 4 days after irradiation. The formation of calcified nodules was observed by alizarin red staining at 1,3,10,14 days after irradiation at 4th day of culture, and at 1,4,5 days after irradiation at 14th day of culture. Results : Apoptosis was not induced by 10 or 20 Gy independent of irradiation and culture period. Irradiation did not induced Gl arrest in post-irradiated ostedblasts. After irradiation at 4th-day of culture, G2 arrest was induced but it was not statistically significant after irradiation at 14th-day of culture. In the case of irradiated cells at 4th day of culture, calcified nodules were not formed and at 14th-day of culture after irradiation, calcified nodule formation did not affected. Conclusion : Taken together, these results suggest that Irradiation at the dose of 10-20 Gy would not affect apoptosis induction of osteoblasts. Cell cycle and calcified nodule formation were influenced by the level of differentiation of osteblasts. (Korean J Oral Maxillofac Radiol 2000; 30: 189-198)

영지 균사체의 액체배양에 의하여 생산된 세포외 다당 시료를 분획하였고, 이들 각 분획에 대한 항암 활성을 균사체 유래 다당 분획들과 비교하면서 조사하였다. 배양여액으로부터 세포외 수용성 다당(BWS)을 얻었고, 이를 순차적으로 이온교환 및 겔 크로마토그라피 하여 BWS를 포함한 세포의 수용성 다당 분획, 총 5종을 얻었으며, 균사체 유래의 수용성 다당(MWS)에서도 세포외 다당과 동일한 방법으로 분획하여 총 5종의 분획을 얻어 대조구로 시용하였다. 세포외 다당 시료들의 항보체 활성(ITCH_50, %)은 15~30% 정도로 15~70%인 균사체 유래 다당 분획들의 값보다는 낮았으나, 이들 세포외 다당 분획들의 값보다는 낮았으나, 이들 세포외 다당 분획들중, BWS-DA와 BWS-DA-GI는 1000 ㎍/ml의 시료 농도에서 30% 정도의 매우 높은 활성을 나타내었다. MTT assay에서는 mouse leukemia L1210에 대하여 BWS-DN 및 MWS가 600㎍/ml의 농도에서 각각 86 및 89%의 높은 저해율을 나타내었으며, BWS-DA 및 MWS-DN의 경우는 3㎍/ml의 매우 낮은 농도에서도 32~35%의 저해율을 보였다. 또 human cell line인 COLO-205에 대해서는 BWS와 BWS-DA 및 MWS-DA가, 그리고 HL-60에 대해서는 BWS-DA와 BWS-DN 및 MWS-DN이 각각 300㎍/ml의 시료 농도에서 약 50%(IC_50)의 높은 저해능을 나타내었다. Exo-polysaccharide (BWS) obtained from submerged cultivation of Ganoderma lucidum mycelium was fractionated. Antitumor activity of their fractions was investigated in comparison with the mycelial polysaccharide fractions. Eight kinds (BWS-DN, BWS-DA, BWS-DN-GI, BWS-DA-GI, MWS-DN, MWS-DA, MWS-DN-GI and MWS-DA-GI) of polysaccharide fractions were obtained by DEAE-cellulose ion exchange chromatography and Sepharose CL-4B gel chromatography from BWS and MWS, which were isolated from culture fluid and mycelial cell, respectively. The anticomplementary activities (ITCH_50, %) of the exo-polysaccharide fractions showing 15% to 30% were lower than those of mycelial polysaccharide fractions showing 15% to 70%. The acidic fractions of BWS-DA and BWS-DA-GI fractionated from BWS, showed the highest activity of 30%. In the MTT assay, BWS-DN and MWS against mouse leukenia L1210 exhibited high inhibition ratio of 86 and 89%, respectively at the concentration of 600 ㎍/ml. High inhibition ratio of 50% (IC_50) was achieved for BWS, BWS-DA and MWS-DA fractions against human colon adenocarcinoma COLO-205 and for BWS-DN, and MWS-DN fractions against human leukemia HL-60 at the concentration of 300 ㎍/ml among the six polysaccharide fractions, respectively.

This study proposes a new analytical method for assessing outage cost of composite power system with considering transmission system. Uncertainty of outages of generation system and transmission can be included. Composite power system ELDC(CMELDC) on HLII is developed and proposed newly from reliability evaluation of composite power system in order to analysis the outage cost on HLII. Equivalent outage cost of transmission system(EOCTS) is proposed newly in this study too. This means the outage cost conversed from unarrival which is power occurred by the outage of transmission system. The effectiveness of the proposed approach is demonstrated by the two case studies. The results show that this approach can evaluate the equivalent price of the outages of transmission lines.

Renal vein thrombosis (RVT) is not an uncommon condition amongst patients with nephrotic syndrome or malignancy. Septic pulmonary embolism (SPE) is associated with risk factors such as intravenous drug use, pelvic thrombophlebitis, and suppurative processes in the head and neck. However, acute pyelonephritis is a rare cause of RVT and SPE. Case reports on RVT and SPE due to acute pyelonephritis are rare. In most of the earlier cases, patients had underlying conditions such as diabetes mellitus, renal carcinoma, calyceal stones, and hyperhomocysteinemia. We report a case of acute pyelonephritis complicated by RVT and SPE that occurred in a patient without any predisposing risk factors for thromboembolism. RVT and SPE were diagnosed using computed tomography and ventilation/perfusion scan. The patient recovered with antibiotics and anticoagulation therapy without any surgical interventions.

Rhinocerebral mucormycosis is a well-described fulminant fungal infection that typically presents in a rapidly fulminant manner. This condition is more likely to occur among patient with diabetes mellitus, malignant tumors, who have long-term steroid treatment, or who suffer from some debilitating diseases. We report 3 cases of rhinoorbitocerebral mucormycosis, all suffered from diabetes mellitus. In all 3 cases, endoscopic sinus surgery was done and the antifungal agent(amphotericin B) was administered intravenously, and two patients died. One survivor who had focal extension of paranasal sinus and orbit, required one surgical intervention without orbital exenteration and he is alive without recurrence disease. The severity of the disease is probably dependent upon the gost resistance to the invasion of phycomycetes. Early diagnosis and immediate, effective treatment are the key for cure of the disease.

측백나무 추출물의 Monoamine Oxidase 저해활성

이문순,오지훈,이학수 忠北大學校 農業科學硏究所 2012 農業科學硏究 Vol.28 No.2

Monoamine oxidase (MAO) exists in the outer membrane of mitochondria and contained a flavin adenine dinucleotide (FAD). MAO is classified into two forms, A-type (MAO-A) and B-type (MAO-B) on the basis of their different specifications toward substrates and inhibitors. This study was carried out to identify inhibitory components on MAO from Thuja orientalis seed extract by bioassay- guided isolation. The seeds of Thuja orientalis was extracted with 80% MeOH, and the MeOH extract was fractionated with n-hexane, chloroform, ethylacetate and n-butanol successively. The n-hexane and chloroform fraction showed relatively high inhibitory activity on MAO. Among the fractions from n-hexane layer through silicagel column chromatography, the fractions 2, 3 and 4 showed strong inhibitory activity on MAO
