Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

This paper describes the speed control method of BLDC Motor using TDOF PI ( Tow-degree of freedom PI ). PI control method generally used has difficulty in efficient speed control because speed response and load torque response interfere each other. It can't decrease the overshoot of motor speed w rm, and shorten the response time of load torque TL, at the same time according to the step alternation of speed reference w rm. Therefore TDOF PI is applied to BLDC Motor in order to supply these weak points of PI control method in this paper. TDOF PI can get the torque characteristic of short response time as well as stable and prompt speed adjustment by separate control for speed response and load torque response. The results from the tests of C program simulation and system construction show that TDOF PI is superior to PI control system in speed adjustment and load torque response.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Han, Seong-kyu,Park, Jin-bong,Kim, Doo,Park, Sang-kyoon,Lee, Ho-sung,Kim, Seong-nam,Chang, Byoung-sun,Ryu, Pan-dong The Korean Society of Veterinary Science 1999 大韓獸醫學會誌 Vol.39 No.2

Bovine somatotropin is known to improve the growth rate and lactation in cattle. In this study, we examined the concentration-time profiles of a sustained-release formulation of bovine somatotropin (BST) and insulin-like growth factor-1 (IGF-1) in plasma and milk in cows. In addition, the possible effect of co-administrated vitamin ADE complex on the pharmacokinetic parameters of BST and IGF-1 was evaluated. 1. Plasma BST and IGF-1 levels reached the peak at 12~24 and 48 hours after the administration of BST, and plasma half-lives ranged 100 to 137 and 201 to 310 hours, respectively. To 8th day after administration, BST and IGF-1 levels in milk were not significantly different from the control levels. 2. Plasma BST levels showed cyclic pattern with high concentrations in early stage after each injection and following gradual declining during repeated administrations at 2 week intervals, while plasma IGF-1 levels in treated animals did not show such a cyclic pattern, but remained higher than the control levels. 3. Milk BST and IGF-1 levels during repeated treatments were not significantly different from the control levels. 4. Co-administration of vitamin ADE complex yielded slightly increased AUC of plasma BST for high dose group, but such effect was not evident in the IGF-1 levels. Co-administration of ADE complex tended to increase plasma BST levels and decrease the elimination half-life of IGF-1. 5. These results suggest that the BST formulation tested is one of the ideal sustained-release formulation for long term use in dairy industry. As for the co-administration of vitamin ADE complex, the benefit of co-administration with BST is needed to be further evaluated.

한성식(Seong-Sik Han),장성원(Seong-Won Jang),이양섭(Yang-Sub Lee),우봉철(Bong-Cheol Woo),정순필(Soon-Phil Jung),이관섭(Kwan-Sup Lee) 대한영상의학기술학회 2014 대한영상의학기술학회 논문지 Vol.2014 No.1

목 적 : 급성 외상 환자의 상부경추 검사 시 환자의 움직임이나 자세 잡이의 어려움으로 재검사가 많은데, 이러한 재검율을 최소화 하기 위하여 변형된 open mouth view를 적용한 검사의 유용성을 평가하고자 하였다.  대상 및 방법 : 성인 팬텀을 대상으로 안와외이공선을 검출기면에 수직이 되도록 하고, 초점과 피사체 간 거리를 100cm으로 고정한 후, X선관의 각도를 머리쪽으로 각각 0°, 5°, 10°, 15°, 20°, 25° 를 설정하고 제 1경추와 제 2경추의 높이인 상치열(teeth incisor)을 중심 X-선으로 촬영하였다. 영상평가는 5년차 이상 방사선사 10명이 PACS의 모니터 영상을 통하여  ‘Excellent’ 5점, ‘Good’ 4점, ‘Fair’ 3점, ‘Poor’ 2점, ‘Very poor’ 1점으로 부여하여 육안적 평가를 하였으며,  Kruskal wallis test와 Mann-Whitney로 통계적 분석을 하였다. 결 과 : 응답 점수의 평균은 15°에서 5.0점으로 가장 높게 평가 되었다. Kruskal wallis test 검정 결과에서는, 15°에서 55.5점으로 가장 높게 나타났고 20°에서 40.6점으로 나타났다. Mann-Whitney 사후 검정 결과 0°와 5°, 10°와 20°를 제외한 방법들은 통계적으로 유의하였다(p<0.05). 결 론 : 급성 외상 환자의 상부경추 검사 시 환자의 움직임 없이 중심 X-선의 각도만을 변화시킨 변형된 open mouth view는 진단적 가치가 우수한 유용한 검사법이라고 사료된다.   Purpose : This study is to evaluate the modified open mouth radiography which is valuable and minimizes the reexamination rate in case of acute trauma patient. Materials and Methods : The modified open mouth view was taken changing x- ray angles of 0°, 5°, 10°, 15°, 20°, 25° toward to the head with orbitmeatal line of the phantom perpendicular to the detector, and the focus-object distance was 100cm. The center of x-ray was teeth incisor that is the same anatomical level as the atlas(C1) and axis(C2). All the images were evaluated by ten radiological technologists who have over five-year work experiences and 5-point Lickertis scale throughout visual evaluation in PACS system was used. Statistical significance was analyzed by Kruskal wallis test and Mann-whitney test Result :  In response to mean score of Likertis scale, the image of 15° was highly evaluated as 5.0 points among the group. The result of the Kruskal wallis test, the image of 15° was ranked first as 55.50 points and the image of 20° was scored 40.60 points secondly. All the results of the Mann-whitney post-hoc test, except between 0° and 5°, 10° and 20°, indicated statistical significant differences(p<0.05). Conclusion : In case of patient with acute upper cervical spine trauma, the modified open mouth radiography can minimize patient s movement and can make them more comfortable and bringing satisfaction. In addition, it can get a high quality image without specific positioning. As a result, the modified open mouth radiography would be useful and applicable to the clinical practice especially for acute trauma patients.
