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.

The in vitro and in vivo activities of CH1250, a new β-lactamase inhibiting compound, were compared with the activities of clavulanic acid and sulbactam against 30 β-lactamase-producing bacteria. Broth microdilution susceptibility testing was performed to compare the activities of β-lactamase inhibitors. Serial two fold dilutions of β-lactams were tested alone and in two combinations with β-lactamase inhibitor. CH1250 was more active than clavulanic acid against Acinetobacter calcoaceticus S21, Pseudomonas aerug-nosa GN918, Proteus vulgaris 20, Staphylococcus aureus MS15009/1258, Serratia marcescens 1 when combined with cefotaxime. When combined with amoxicillin, CH1250 was more effective against Citrobacter diversus 2046E. Staphylococcus aureus MS25009/1258, Proteus vulgaris GN76. With ampicillin, CH1250 had an better or simillar activities against Escherichia coli 3455E, Klebsiella aerogenes 1976E, Serratia marcescens 1, Staphylococcus aureus MS15009/1258. The efficacy of ampicillin-CH1250 in treatment of mice with systemic infections produced by Klebsiella aerogenes 1976E, a β-lactamase-producing bacteria, was compared with that of ampicillin, ampicillin-sulbactam. Acute systemic infections in mice were produced by i.p. inoculation of bacterial cultures suspended in 6% mucin. Mice were treated s.c. 1hr after challenge. PD50s of the ampicillin, ampicillin-sulbactam. ampicillin-CH1250 were 334.32, 170.58, 250.5mg/kg, respectively. CH1250 was not more effective than sulbactam in reducing ampicillin doses required to protect mice from infection produced with Klebsiella aerogenes 1976E. The reduction in the 50% protective dose of ampicillin by CH1250 was 23% better than those effected by sulbactam for Klebsiella aerogenes 1976E infection.

비저지 시스템을 강력하게 추진하려는 전송설비와 통신망에 저속 코딩 기술이 출현하고 있다. 본 논문에서는 하나의 국제 표준 ISDN 기본율 접속을 통한 ADPCM 음성전송을 위하여 스위치 액세스 구조를 제안하였다. 제안한 구조에서는 2개, 3개 또는 4개의 음성 터미날과 데이타 터미날이 접속을 통하여 동시에 동작될 수 있다. 다양한 기술적 내용을 논의하였으며 제안한 기본율 접속구조, 기본율 S와 T 접속 비트 프레밍 요구와 Q.931 호 제어와 새로운 구조에 필요한 회선할당 절차를 논의하였다. 연구결과 기존 ISDN 스위치에서 제안한 구조로 갱신하는데 비교적 간단한 하드웨어 추가로 될 수 있고 표준 ISDN S와 T접속은 그대로 유지된다. This paper proposes a switch access architecture for Adaptive Differential Pulse Code Modulation voice transimssion over a single international standard Inetegrated Services Digital Network, Basic Rate Interface. In this proposed architecture, data terminals with two voice terminals, three voice terminals, or four voice terminals can be operated simultaneously through the interface. Various technical topics are dicussed : the proposed Basic Rate Interface architecture. BRI S and T interface bit framing requirements and the Q.931 call control and channel assignment procedures required for the new architecture. The study results show that relatively simple additional hardware could be used to upgrade an existing ISDN switch to this proposed architecture and the standard ISDN S and T interfaces remain intact.

Neomorphogenesis of cartilage using chondrocyte-polymer constructs is a potential source for development of cartilage reconstruction. Current tissue engineering techniques of neocartilage rely on in vivo implantation of polymer-chondrocyte constructs. The purpose of this study was to find a way to bioengineer cartilage in vitro by entrapping chondrocytes in a molded autologous fibrin glue. Chondrocytes isolated from the cartilage of rabbit joints were combined with fibrinogen extracted by a single cryoprecipitation of autologous plasma, and they were then polymerized with thrombin to create a fibrin glue with a final cell density of 2.5x10?? cells/ml. The collagen for a control study was used as a polymer. The polymer-chondrocyte constructs were cultured for 4 weeks and the fibrin-chondrocyte constructs molded in the shape of a human ear were cultured for 6 weeks in vitro. Morphometric, histochemical, and histomorphometric analysis including glycosaminoglycan quantitation confirmed the following results: 1) Highly-concentrated autologous fibrinogen was easily extracted by a single cryoprecipition of autologous olasma. 2) The fibrin-chondrocyte constructs demonstrated the presence of actively proliferating chondrocytes with the production of cartilaginous matrix(collagen and glycosaminoglycan) at 1 week after culture, as well as gross and histologic evidence similar to those of normal cartilage at 3∼4 weeks after culture. 3) The collagen-chondrocyte constructs demonstrated lower degrees of hardness and transparency, as well as a lower density of cells and glycosaminoglycan during the culture period. 4) Neocartilage generated from fibrin-chondrocyte constructs in the shape of a human ear nearly retained their original configuration and size without degeneration for 6 weeks of culture in vitro. This study demonstrated a novel method for bioengineering the molded cartilage in vitro using autologous fibrin glue as a matrix scaffold. The generated cartilage showed gross and histologic evidence similar to those of normal cartilage, retaining the original gross dimension. With further refinement, this may be a new application of tissue engineering for the reconstruction of cartilage.

Modeling a CPS system which prtoritize handover requests in order protect ongoing calls from forced termination as queueing system in cellular communication networks. The number of total channels and dedicated channel for handover were decided by analyzing a model, with satisfy GOS constraint. The CPS is simple prioritization scheme, however it provide high quality of services and improved performance in the total admitted traffic. In view of total system it is possible to assign a frequency channel to each cell. In this paper, we provide a method of channel assignment strategies along with the complexity in cellular systems. The proposed channel assignment method improved quality of services by adapting to practical problems.

홍진표 안양대학교 산업기술연구소 2000 自然科學硏究 Vol.7 No.-

본 논문에서는 계수분할을 이용하여 웨이블릿 패킷 변환된 영상을 부호화하는 방법을 제안한다. 전체적인 수행시간을 줄이기 위해 엔트로피를 이용하여 영상을 웨이블릿 패킷 분할하고, 부대역간의 상관성을 이용하여 계수들을 제로트리 방식으로 부호화하여 비트율과 왜곡면에서의 성능을 보완한다. 영상 복원시오차를 감소시키기 위하여 각 주파수 부대역간의 상관성을 이용한 새로운 부모-자식노드 관계를 도출하고, 이를 이용하여 계수들에 대한 부호화 순서를 결정한다. 그 결과 새로운 웨이블릿 패킷영상 부호화기는 비트율과 제곱오차에 대해서 기존의 방법과 비교 평가하였을 때 우수한 성능을 나타내었다. A wavelet packet image coder which is based on the coefficients partition for efficiently encoding the image is proposed. The wavelet packet decomposition scheme by the first-order entropy provides a fast implementation of the encoder and the zerotree-based coding a very good rate-distortion performance. To reduce the reconstruction error, a new parent-children relationship using the correlation between the subbands is proposed and then the wavelet packet coefficients are partitioned by a new order. The result indicate that this new wavelet packet image coder produces the satisfiable performance both compression rate and quadratic error. The computer simulation is applied to evaluate performances of the designed network. The algorithm proposed in this study is a heuristic one with polynomial time complexity. This method was tested on sample problems and proved to be superior to the conventional ones.

人體組成 및 體力에 關한 硏究 : 韓 ·日 女子大學生 對象 Korean and Japanese young female subjects

洪進杓,增田卓二 대구효성가톨릭대학교 1993 연구논문집 Vol.47 No.1

The body composition and nutronal state of the Korean and the Japanses young female subjects were compared. Three-day individual weighed, dietary intakes and anthropometric measurements were ditermined in 48 Korean and 60 Japanese female subjects, 19 to 23 yr of age, from the divisions of dietetics. The body composition estimates were measured by bioelectrical impedance-total body water (BI-TBW) method. There were no significant differences between the Korean and the Japanese young females in body size and body shape, but the endomorphy score in the Heath-Carter somatotype method of the Japanese young females was higher than those of the Korean young females. The Korean young females had lower estimated total body fat and internal fat that calculated by BI-TBW method, but there was no great difference butween the Korean and the Japanese in subcutaneous fat. In contrast, the Korean young females are reproted to have the same total energy expenditure per day as the Japanese young females and the total enerfy intaker and carbohydrate energy intake ratio per day were significantly higher than those of the Japanese young females. the differences in body fat distribution and energy intakes in the Korean, and the role of capsaicain in red papper are discussed as a possible determinant of teh internal fat in the Koren vs Japanese.
