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.

Photobacterium phosphoreum을 고정화하기 위한 최적 Carboxymethylcellulose(CMC) 담체의 농도결정

이용제,전억한 경희대학교 생명자원과학연구원 1999 硏究論文集 Vol.20 No.-

CMC 담체는 점도가 큰 물질로 luminometer tube내의 사료에 유동을 최소화함으로써 산소의 공급을 일정하게 하여 bioluminecsence의 intensity를 일정하게 측정 할 수 있고, P phosphoreum을 고정하여 30분 후에 bioluminescence의 안정성을 가지므로 바로 측정할 수 있는 장점을 가지고 있다 독성에 민감하고 bioluminescence에 영향을 주지 않는 CMC의 농도(w/v)의 결정은 중요하며 1%(w/v) CMC 담체에 고정했을 때 bioluminescence의 유지가 가장 안정했으며, Cr 화합물에 대한 민감하게 반응하는 CMC 담체의 EC_50값ㅇ르 г값을 이용하여 산출했을 때 1% CMC 담체에 고정하였을 때 적은 독성 농도에서 민감한 bioluminescence의 감소를 볼 수 있었다. 그러므로 독성모니터용 P phosphoreun의 고정화 담체로 CMC의 1%(w/v)가 최적 농도이다. Bioluminescence of Photobacterium phosphoreum has been used for the detection of pollutants in the environment. Immobilization method was used to maintain the stability of bioluminescence of P. phosphoreum. Carboxymethylcellulose was investigated for immobilization of P. phosphoreum as a matrix without disturbance in bioluminescence emission. Maintenance of bioluminescence was determined from the P. phosphoreum immobilized on the various concentrations of carboxymethylcellulose. Relatively high bioluminescence intensity was observed with cells immobilized on 1%(w/v) carboxymethylcellulose. The effect of carboxymethylcellulose concentrations on the sensitivity of Cr-compounds including Na_(2)CrO_(4), K_(2)CrO_(4), CrO_(3), CrK(SO_(4))_(2) and CrCl_(3) to the bioluminescence intensity was investigated. The calculated EC_(50) showed that the linear relationship between such substances and bioluminescence.

제영지,장민희,임용규,이동렬 대한치과교정학회 2007 대한치과교정학회지 Vol.37 No.5

본 실험은 마찰력을 줄이고 물리적 성질을 개선하여 최근에 개발된 수 종의 심미 브라켓들과 교정 탄선간에 발생하는 마찰력의 크기를 측정, 비교해 보고자 하였다. 일반 슬롯의 세라믹 브라켓인 Inspire, Signature III와 Cristaline V, 스테인레스 스틸 (SS) 슬롯을 가진 세라믹 브라켓인 Clarity, 골드 슬롯을 가진 Luxi II, Polyoxymethylene 계열의 플라스틱 브라켓인 Brillant, SS 슬롯을 가진 컴파짓 브라켓인 Spirit MB, 금속 브라켓인 Integra를 사용하여 018″ 원형의 교정 탄선에 0˚, 4˚, 8˚의 tip angulation을 부여하고 elastic module로 결찰한 뒤 인공 타액 상태에서 활주이동할 때의 운동 마찰력을 측정하였다. 연구 결과 슬롯에 silica 처리된 세라믹 브라켓 (CR)이 유의하게 낮은 마찰력을 보였고 (P < 0.05), 단결정 세라믹 브라켓이 (IN) 유의하게 큰 마찰력을 보였다 (P < 0.05). 플라스틱 브라켓인 polyoxymethylene계열의 BR이 낮은 마찰력 양상을 보였고 이는 금속 브라켓과 유사하였다. 모든 브라켓에서 브라켓-탄선 각도가 증가함에 따라 유의하게 마찰력이 증가하였으나 주사전자현미경상에서 탄선이나 브라켓에 손상은 발견되지 않았다. 마찰력의 양상이 브라켓의 재질로 추측할 수 있는 것과는 다르게 나타난 결과로 보건대 심미 브라켓이 스테인레스 스틸 브라켓에 비해 마찰력 면에서는 오히려 우수하거나 큰 차이가 없으므로 임상적으로는 마찰력은 크게 고려하지 않아도 되겠다. Objective: The purpose of this study was to evaluate how the friction that occurs during the sliding movement of the archwire through esthetic brackets is differently affected by bracket materials, slot designs, and tip angulations of the archwire. Methods: Eight types of brackets with 0.018 inch slots (composite: Brillant (BR); composite with metal slot: Spirit MB (SP); ceramic: Inspire (IN), Signature (SI), Cristaline V (CR); ceramic with metal slot: Clarity (CL), Luxi II (LU); and metal bracket: Integra (IT)), and placed into groups of 20 brackets in each group, were tested in artificial saliva with 0.018 inch stainless steel wire. The wire tip angulations were given as 0, 4 and 8 degrees. Results: CR group significantly showed the lowest frictional force with all wire tip angulations of 0, 4, and 8 degrees. IN significantly showed the highest frictional force (P < 0.001). BR (Polyoxymethylene) had significantly less frictional force than SP (Polycarbonate) (P < 0.001) and showed no significant difference between metal brackets. Friction was increased as the wire tip angulations were increased, but no notches were observed on any parts of the archwire. Conclusions : According to the results of this study, esthetic brackets are superior or similar to SS brackets from a frictional point of view.

공중합에 의해 제조된 온도와 pH 응답성 하이드로젤의 체적 전이온도, 팽윤거동 및 방출 특성 변화

이제용,김형일 한국공업화학회 2003 응용화학 Vol.7 No.2

Temperature and pH-responsive hydrogels were prepared with the combination of various monomers such as N-isopropylacrylamide (NIPAAm), acrylamide(AAm), n-butoxymethylacrylamide (nBMA), poly(ethylene glycol) methyl ether methacrylate (PEG), and acrylic acid (AAc). 2,4-Dichlorophenoxyacetic acid was chosen as the herbicide loaded into hydrogel. Volume transition, swelling behavior and release property were studied for these hydrogels. Poly(NIPAAm) hydrogel showed the sensitivity to the thermal stimuli at around 30℃ with a large volume change. nBMA was incorporated in a proper composition for the preparation of thermal stimuli-sensitive hydrogels which had a sharp volume transition temperature around 15℃. The hydrogels which have AAc as one of their components showed very different behavior depending on the pH. Volume transition temperature, degree of swelling and release rate were varied significantly depending on the content of comonomer, graft, and crosslinker.

이동우,강웅구,류인균,정도언,조맹제,우종인,김용식,권준수 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.3

연구목적 : 강박증의 동반인격장애에 관한 연구들은 기존의 개념과 달리 강박성 인격장애와 강박증 간에는 특이적인 관계가 없으며, 강박증 환자들은 다양한 인격장애를 동반한다는 결과를 보여주었다. 그러나 이러한 연구들은 동반 인격장애에 관한 기술적인 분석에 그쳤고, 강박증 환자군의 임상 증상과 동반 인격장애 양상간의 연관성에 관한 분석을 시행하지 않았다. 본 연구의 목적은 강박증 환자군에서의 동반 인격장애를 평가하고 강박증 환자의 다양한 증상과 동반 인격특성 간의 연관성에 대해 연구하는 것이다. 방 법 : DSM-IV의 강박증의 진단기준을 만족하는 59명의 환자군과 32명의 정상대조군을 대상으로 인격장애 질문지를 적용한 후 4∼6점의 절단점을 기준으로 인격장애의 진단이 내려졌다. 먼저 환자군과 정상대조군 간의 특정 인격장애 빈도의 차이를 알아보기 위하여 Fisher's exact test를 시행한 후, 두집단 간에 유의한 차이가 있는 것으로 밝혀진 인격장애 척도 점수에 미치는 Y-BOCS,BDI,BAI점수의 영향을 알아보기 위하여 다중선형회귀 분석을 시행하였다. 결 과 : 1) Fisher's exact test 결과 강박증 환자군은 정상 대조군에 비해 경계성 인격장애(18.6%vs 0%, p=0.007). 회피성 인격장애(55.9% vs 18.8%, p=0.001), 우울성 인격장애(40.7% vs 0%, p=0.000)의 비율이 유의하게 높았다. 2) 다중선형회귀분석 결과 Y-BOCS 점수 (t=2.10, p=0.043)와 BAI점수(t=2.60, p=0.014)는 경계성 인격장애 점수에 유의한 영향을 주는 것으로 나타났다. 또한 BAI점수(t=3.23, p<0.003)는 회피성 인격장애 저수에, BDI점수 (t=3.08, p=0.004)는 우울성 인격장애 점수에 유의한 영향을 주는 것으로 나타났다. 결 론 : 강박증 환자군은 정상 대조군에 비해 회피성 인격장애, 우울성 인격장애, 경계성 인격장애의 동반율이 높고, 강박증이 경계성 인격장애의 심각도에 유의한 영향을 미치는 것으로 사료된다. The purpose of this study was to assess the comorbid axis-Ⅱ disorders of obsessive compulsive disorder(OCD) patients and to investigate the relationship between symptoms of OCD and the comorbid personality traits. The subjects were 59 patients who met DSM-IV criteria for obsessive-compulsive disorder and 32 normal controls. All subjects completed personality Disorder Questionnaire-IV(PDQ-IV). The patients completed Beck Depression Inventory(BDI) and Beck Anxiety Inventory(BAI), and were rated with Yale-Brown Obsessive Compulsive Scale(YBOCS). The results were as follows. 1) The OCD patients showed significantly higher prevalence of avoidant, depresssive and borderline personality disorder(p<0.01) compared to controls. 2) The BAI score had significant effect on the avoidant personality score(t=3,23, p<0.003). The BDI score had significant effect on the depressive personality score(t=3.08, p=0.004). The YBOCS(t=2.10, p=0.043) and BAI(t=2.60, p=0.014) scores had significant effects on the borderline personality score. We found that OCD patients had higher prevalence of avoidant, depressive, and borderline personality disorders. We also found that obsessive-compulsive symptoms have significant effect on the severity of borderline personalty traits. We suggest that it would be very helpful to consider Axis-Ⅱ disorders for managing patients with obsessive-compulsive disorder.

The international government committee is progressing their agreements about intellectual property protection of traditional knowledge(TK1, gene resource(GR), folklore(FL) in WIPO. It is in the course of selection with precedence of TK, GR, FL in WIPO, focused on discussions about listing of TK documents, standardization of DB construction, sharing and profit distribution of GR. There are disagreements between developed countries and developing countries about intellectual property protection agreements of TK, GR. The developed countries insist on using the existing intellectual property protection, but the developing countries ask new ones on character of TK, GR. It causes intangible assets to be valuable trade properties in future world trade. This research Groped for a summary program about intellectual property protection of traditional knowledge(TK) etc. debating in WIPO. This program confirms that such as TK, GR etc. not only to be the cultural property accumulated in human history, but also to be the original resource may be using at present. Therefore, we suggest that the focus of discussion should transfer to UNESCO instead of WIPO which only deal with the intellectual property protection. Besides, the main body which protecting and supporting TK should become its holding organization so as to achieve more effective management about it. In order to protect and support TK, the government should have firstly the recognition that TK is the property belongs to the country. By this viewpoint, it needs to setup DB through overall excavation of the unofficial knowledges in order to protect and support these TK, GR. Because the positive dealing with those WIPO's discussion means to support our TK, GR, so there should have some reorganization about existing related ones, and also needs systemic supporting policies & management system.

WIPO international government committee will finish to develop toolkit for making documentation on discussions of intellectual property protection with TK, GR until the late 2003. As they construct DB of TK, GR, it becomes in a hurry to construct DB of TK information in Korea. We looked into application of copyright in force and a lot of problems in terms of analyzing medical books in the resent condition or protecting them in Korea. There are 29 kinds which have been lost, 12 kinds which could have read in parts, 136 kinds which have been existed of Korean medical books before 1900. There are also a lot of medical books which have been published after 1900 and still are unpublished. It would be 406 medical books from China totally, 111 kinds from Chosun Dynasty version, 134 kinds from Euybangeuchui, 225 kinds from Hyangyackjibsungbang, 78 kinds from Dongeuybogam. We consider to know whether Korean medical books could been applied to the copyright in force or not in accordance with discussions of WIPO on the period, subject(author), contents of protection. If it is applied to the copyright in force, it will be decided to revise according to discussions of WIPO. On the other hand, the problem which is occurred to protect Korean medical books is friction with China as importing their medical books, to find our medical books actively which has been unpublished. Finally, We have to revise administration and intellectual property standards or protect our medical books by making new administration laws.
