Objectives : One of the objectives of this study is to estimate the prevalence rates of psychiatric diagnoses in the combined populations of psychiatric hospitals, psychiatric nursing facilities and homeless asylums using the Korean version of the Composite International Diagnostic Interview (K-CIDI), which is a comprehensive and fully standardized interview schedule to assess psychiatric disorders for diagnosis. The Other objective is to compare with previously studied prevalence rates of Psy-chiatric diagnoses using the results of this study. Methods : The study subjects, aged from 181o 64 years, were randomly selected from 64,582 institutionalized population of psychiatric hospitals, Psychiatric nursing facilities and homeless asylums as of 30, June, 2001. Twelve trained interviewers administered the K-CIDI to the selected respondents. A total of 1,875 respondents (male 1,194, female 681) completed the interview. Results : The lifetime and one year prevalences of any diagnosis excluding nicotine dependence · withdrawal, anxiety disorder, eating disorder, somatoform disorder were 88.2% (male 88.1%, female 88.3%), and 65.8% (male 62.7%, female 73.7%), respectively. The lifetime and one year prevalences of schizophrenia and other psychotic disorders were 78.5% (male 75.3%, female 83.7%), and 56.8% (male 51.9%, female 64.8%), respectively. The lifetime and one year prevalences of alcohol use disorder (dependence/abuse) were 26.7% (male 37.9%, female 8.3%), and 8.7% (male 12.8%, female 2.1%), respectively. The lifetime and one year prevalences of mood disorder were 18.1% (male 13.5%, female 25.8%), and 10.4% (male 7.2%,female 16.9%), respectively. The lifetime and one year prevalences of schizophrenia and other psychotic disorders were comparable with the 2001 community survey by 1.19% to 1.32%, and 0.51% to 0.61%, respectively. The lifetime and one year prevalences of schizophrenia were also comparable by 0.16% to 0.28%, and 0.16% to 0.25%, respectively. There were no significant changes of prevalence rates when correction were applied to other psychiatric diagnosis. Conclusion : The results of this study could be used for evaluating the distribution of psychiatric diagnoses in mental health related facilities and for planning mental health policies.

In this study, we investigate effects of compositional ratios on zirconium based amorphous films for alternative gate dielectric applications. To obtain amorphous films, Si, Bi as glass former materials are evaluated. The dielectric constant of Zr based films is directly related to the Zr concentration. So higher Zr concentration results in higher dielectric constant. But to obtain good thermal stability, higher glass material concentration is preferred. Amorphous thin films were deposited by reactive co-sputtering because of its easiness on compositional change. However, reactive sputtering easily causes undesirable interfacial layers. In order to reduce the interfacial layers, amorphous films is formed by oxidation. Especially, the amorphous films of Zr_(X)Bi_(1-X)O_(3.5), X = 0.5 prepared by oxidation shows CET (Capancitance Equivalent Thickness) of 17 and leakage current density of 1X10^(-2) A/㎠ at - 1.0V.

연구배경 : 최근의 死亡率중에 腦血管系疾患이 차지하고 있는 比率이 대단히 높기 때문에 氣와 血의 이론적 관계인 "氣爲血之帥, 氣行則血行." 의 관점하에서 腦血管系疾患중의 하나인 血栓病을 동의학적 병리론에 의거하여 "瘀血"의 범주에 속할 것으로 사료되기 때문에 補氣之劑인 황기를 君藥으로하고 活血祛瘀之劑인 桃仁과 紅花를 加하여 실시하기로 하였다. 그리하여 본 연구가 임상에서 血栓症治療에 應用할 수 있는지를 考察하고, 작게는 東醫學 發展의 이론적 뒷받침이 되었으면 하는 바램에서 시행하였다. 방법 : 황기도홍탕이 1첩분량(318.75g)을 100ml로 減壓濃縮하여 0.2mg/kg의 endotoxin을 試料投與 1시간 후에 白鼠의 尾靜脈에 注入하고 4시간이 경과되면 urethane 痲醉下에서 心臟採血 하였다. 결과 : 血小板數와 FDP는 對照群에 비하여 增加 또는 減少되었지만 有意性은 나타내지 않았다. 그러나 prothrombin time과 fibrinogen량은 對照群에 비하여 有意性있게 短縮 또는 增加하였다. 결론 : 황기도홍탕이 endotoxin으로 誘發된 白鼠의 血栓症에 미치는 影響은 有意한 것으로 나타났다. 그렇기 때문에 黃?桃紅湯이 腦血管疾患 뿐만 아니라 瘀血性疾患에 임상적으로 응용하면 보다 높은 치료효과를 거두리라 思料된다 This study was performed to investigate the effect of Whangkidohongtang(황기도홍탕) on the intravascular coagulation induced by endotoxin in rats. The intravascular coagulation was induced by injecting endotoxin in the caudal vein of rats. And these rats were treated with extract of Whangkidohongtang(황기도홍탕)1.0ml/200g (GroupⅠ) and Whangkidohongtang(황기도홍탕) 2.0ml/200g (groupⅡ), which were administered orally. Then, the number of blood cells, platelets, concentration of prothrombin time, fibrinogen and FDP(fibrin-fibrinogen degradation products) were measured. The following results were obtained : 1. The number of platelets increased in the GroupⅡcompared with the control group, but it is not significant. 2. The prothrombin time was shortened significantly in the GroupⅡcompared with the control group. 3. The concentration of fibrinogen increased significantly in the trial group compared with the control group. 4. The degree of concentration of FDP decreased significantly in the trial group compared with the control group, but it is not significantly. According to the above results, it is considered that Whangkidohongtang(황기도홍탕) has the significant effects on thrombosis. Therefore, Whangkidohongtang(황기도홍탕) seems to be applicable to the diseases related to thrombosis.

The purpose of this study is to analysis the change patterns of life style and education of North Korean defectors. The questionnaire of this study is for two hundred North Korean defectors who had entered South Korea in 2001. The questions are about residence, education, legal issue, and health. According to this study, the residences of the defectors were still concentrated on the Metropolitan area. Type of residence has become varied so as to increase proportion of their own-houses and long-term leases. Males had got educated for employment purpose, while females had learned using computer the most. Among age groups, the 20s and the 30s had taken regular education the most. As the length of staying in South Korea had increased, the legal cases had decreased; however, the legal issues had become more complicated. The number of the defectors with chronic diseases has gradually declined; thus, overall health status of the defectors had become better. As the length of staying in South Korea had increased, their needs for supports of basic life had decreased, while the demands for consultation about marriage and legal issues. In the conclusion, we point out several ideas based on this study result, which can be utilized in developing policies and supporting programs for North Korean defector adaptation in South Korea.

In this investigation the PFM(Pulse Frequency Modulation) will be used for optimizing PWM inverter pulse patterns. In traditional the pulse frequency of PWM is kept constant. But modulated PWM's frequency in this study, the sinusoidal inverter's performance should be improved. The PWM pulse patterns are definitely controlled so that the time-integral function of the voltage vectors in the space vector notation may show a circular locus. Further, performance index will be minimized because of minimizing distortion of output current. Finally, these theories are realized using single-chip microprocessor.

Objectives : The aim of this study was to examine the change in attitudes and satisfaction level of North Korean defectors in South Korea over a 3 year period (2001-2004). Methods : In our first study in 2001, a total of 200 detectors were interviewed. In the follow up study after 3 years, 151 defectors were re-interviewed by an in-person interview. Results : The level of satisfaction to the governmental support policy to defectors decreased significantly. However, the general level of satisfaction increased slightly (from 3.52 to 3.56 ; 5-score scale). This shows that North Korean defectors are stably adapting to South Korean society. The level of satisfaction significantly correlated with the defectors' confusion of the different value systems, the defectors' understanding of the South Korean people, satisfaction with their physical and mental health, and the Prejudice of South Korean people to defectors. In terms of the attitudes, the type of schooling, the military service and the communist party membership in North Korea were not related to the change in attitude. However, there was a significant correlation with gender and age. Women showed a greater change in attitude compared to men. Older people had difficulty in understanding the South Korean people, but they showed little psychological affiliation to North Korea. Moreover, they showed a high level of satisfaction with the economic situation in South Korea and had an optimistic viewpoint for their future than younger people. Even though many defectors attended churches, religion was not associated with the level of satisfaction or their change in attitude. Conclusion : The factors that influence the level of satisfaction and attitudes of North Korean defectors have changed over 3 years. Therefore, the government, nongovernmental organizations (NGOs) associated with defectors and the churches need to be more sensitive to these changes and make plans to support the adaptation of defectors to South Korean society.

외경 0.25mm 의 동맥문합에 있어서 항혈전제의 효과

In 1960, Jacobson and Suarez reported a 100 per cent patency rate following the anastomoses of vessels which were 1.6 to 3.2 mm in diameter. This report speeded modern-day microvascular surgery up for the last 20 years. High patency rate is reported in microvascular anastomosis of the 1.0mm diameter, and microvascular surgery is widely used in clinical practice. Improvement in methosds of microanastomoses and development of the microvascular instruments, including the operating microscope along with the microsutures make the microvascular anastomoses of vessels that are less than 0.5mm in diameter opssible. The key problem microvascular surgery is the formation of thrombus which is mainly composed of platelets, causing occlusion of the anastomotic site. So much efforts have been made in developing effective anticoagulants. Currently used systemic anticoagulants are heparin, aspirin and persantin. Aspirin inhibits collagen-induced platelet aggregation and the primary action of persanin is to inhibit platelet aggregation to ADP, collagen, and epinephrine, is widely used as effective anticoagulant for patients of atherosclerosis, hemodialysis, and subarachnoid hemorrhage. An animal study was carried out to investigate the opssibility of tichlopidine-HCI to be used as a choice of anticoagulant in microvascular surgery. One hundred and twenty rats were divided into 3 groups. Group A was the control group. Aspirin and Persantin were given orally in group B. Ticlopidine-HCI was given orally in group C. A superficial epigastric artery as small as 0.25mm in hage devised autogenous fascia and silicone rubber tube method to splint the suture line and reduce the bleeding casued by anticoagulants. Fewer sutures were required, saving time and effort in microvascular repair. The results were as follows: 1. At 20 minutes after anastomoses, the patency rates were 100% in all groups. 2. At 3 days after anastomoses, the patency rates were 75% in the control group(A), 75% in the aspirin-persanting group(B), and 80% in the ticlopidine group(C). 3. At 3 weeks after anastomoses, the patency rates were 70% in the group A, 75% in the group B, and 80% in the group C. It is concluded that the ticlopidine-HCI may be used in the microvascular anastomoses of very small arteries as the anticoagulant of choice.
