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.

To investigate psychopathoIogy and executive functions of attention deficit hyperactivity disorder (ADHD) children according to intelligence level, this study included 197 ADHD children who visited the outpatient department of neuropsychiatry of YeungNam University Medical Center, from July 2000 to June 2002. The children were divided into groups based on their intelligence levels. They were compared by the Personality Inventory for Children (PIC), Conncers' Continuous Performence Test (CPT), and Wisconsin Card Sorting Test (WCST). There were significant differences in PIC, on the subscales of verbal development, socialization and autism. In the CPT, there was no significant difference. In the WCST, there were significant differences in the total number of errors, the number of perseverative errors, the number of completed categories and the number of trials needed to complete the first category. Considering these results, the intelligence level of ADHD children is related to their disabilities and behavioral symptoms.Executive functions such as abstract thinking, categorization, working memory and flexibility had significant relationship to the intelligence levels of ADHD children. Therefore, the intelligence level of children with ADHD influences the higher executive functions of regulating attention and information processing rather than attentional functions and capacity alone.

A transient axistymmetric model is used to simulate the thermal and conversion characteristics of a monolithic catalytic converter operating under warm-up conditions. The model takes into account the gas-solid heat and mass transfer, axial and radial heat conduction, chemical reactions and the attendant heat release, and heat loss to the surrounding. The model has been used to analyze the transient response of an axisymmetric ceramic monolith system (catalytic monolith, mat, and steel shell) during warm-up with respect to heat loss and flow nonuniformity at inlet. Numerical solutions indicate that wall temperature and CO conversion efficiency are much more dependent on the flow nonouniformity than that loss. Three dimension effects due to heat loss to the surrounding is localized near the steel shell. The flow nonuniformity plays a major role even inside the catalytic monolith. The convective that transfer due to flow nonuniformity balance with the exothermic reaction and this balance determiness steady state temperature distribution. As the amount of catalytic material increase the exothermic reaction becomes dominant in steady state.

탈취제로 이용되고 있는 지렁이 분변토로 부터 황화수소를 제거하는 황산화 세균 CP-5를 분리하였다. 이 균주는 운동성이 없고 Gram 음성인 단간균 이었으며, cytochrome oxidase와 catalase test에 양성 반응을 보였다. CP-5 균주는 환원형 황합물을 기질로 하는 배지에서 독립영양적인 생장이 가능하였다. 이 균주는 thiosulfate 에서 tetrathionate를 중간생성물로 하여 최종적으로 sulfate로 산화하고, elemental sulfur를 일단 thiosulfate로 산화한 후, sulfate까지 재산화하는 것으로 사료되었다. 독립영양 배지에 yeast extract 를 첨가하면 균의 생장이 촉진되었다. CP-5 균주 현탁액에 H₂S를 2vvm의 유속으로 주입하면 140ppm까지는 거의 완전하게 제거 가능하였다. 본 연구결과로부터 CP-5 균주는 분변토에서 황화수소를 제거하는 대표적인 탈취균주이며, 황화수소 제거를 위한 생물학적 탈취 공정에 활용 가능하다는 것을 알 수 있었다. A new sulfur-oxidizing bacterium which was capable of degrading hydrogen sulfide was isolated from earthworm casts using deodorant materials. The cell of isolate CP-5 was short rod, gram negative and non-motile, the activities of cytochrome oxidase and catalase were positive. The isolate could autotrophically grow in the basal mineral medium supplemented the reduced sulfur compounds such as thiosulfate and elemental sulfur. This bacterium could oxidize thiosulfate and elemental sulfur to sulfate, and the metabolic intermediates were considered as tetrathionate and thiosulfate, respectively. The removal of hydrogen sulfide by the isolate CP-5 was confirmed, and the CP-5 was regarded as one of microorganisms responsible for degradation of hydrogen sulfide in earthworm casts. The isolate CP-5 can be applied to biodeodorization systems for the improvement of removal efficiency of hydrogen sulfide.

Load distribution in group piles is an important matter of consequence for the safe design and the economical design. In the group piles, the model tests were to investigate the effects on spacing-to-diameter ratio of pile, number of piles and arrangement of the pile. The tops of pile were all set to rotate freely. This paper considered the load distribution by the location of the pile as compared the behavior of group piles with single pile. For a three row pile group at 3D spacing, the measured individual row distributions were 35~38%(lead), 32∼34%(middle) and 27∼30%(tail). This results were compared very favorably to those by McVay et al(1995). The shadowing effect for the parallel direction of lateral loading appears to be more significant than the one for the perpendicular direction of lateral loading.

A numerical procedure for the analysis of transient behavior of a monolithic catalytic converter is presented. The thermal behavior of a monolithic catalytic converter is fully coupled with mass transfer and exothermic reaction between exhaust gases and the catalytic converter. In the present study, all these processes are solved simultaneously. The heat transfer process is also simply modelled by using combinging one dimensional convention and conduction and the chemical reaction is also simply modelled by using the concepts of reaction rate and reaction heat. All the partial differential equations for the heat transfer, mass transfer and chemical reactions are approximated by using finite volume method. Resulting algebraic equations are solved using the Newton's method. To see the workability of present numerical method, two well known problems, step increase and step decrease in the gas inlet temperature, have been calculated. Present numerical method shows a good convergence behavior for two test cases : converged solution were obtained with 8 iteration (for tolerance of ??)at most through out the whole calculation domain of space and time. Comparison of present solutions with previous solutions shows a good agreement.

Objective : To compare two different methods of rigid fixation in postoperative stability after mandibular setback, Material and Methods : 28 patients with Class III malocclusion were treated by bilateral sagittal split ramus osteotomy(BSSRO) and mandibular setback were selected for this study. Group A(n=14) had the bone segments fixed with monocortical miniplate on the lateral side of the mandibular body and Group B(n=14) had three noncompressive bicortical screw inserted at the genial area through a transcutaneous approach. Cephalograms were taken preoperatively, postoperatively within 1 weeks and at a follow-up period (mean 8.9 months after surgery) and the amount of setback and postoperative change were measured. Results : Postoperative relapse between two groups was minimal in setback of the mandible. Statistical analysis showed no significant difference in postoperative relapse. Conclusion : This study suggests that both methods of skeletal fixation investigated give comparable postoperative stability and their use in mandibular setback appears to be a fairly stable clinical procedure.

Sulfur dioxide (SO_2), a kind of air pollutant, causes harmful damage to human body. In particular, inhalation of sulfoxide dioxide has been demonstrated to result in the injury to the upper respiratory duct. However, mechanisms by which SO_2 affects these tissues remain to be clarified. In the present study, to investigate the mechanism of SO_2 effects, the influence of SO_2 exposure was examined in terms of the injury of lung and the expression pattern of laminin in the basal lamina. The basal lamina is an important tissue for the regulation of internal respiration by composing of air-blood barrier. Sprague-Dawley rats repetitively exposed to a mixture of O_2 gas and SO_2 gas (250 ppm) for 30 minutes a day were sacrificed to observe the distribution of laminin in the alveolar septum as well as the morphological alteration of alveoli using immunohistological methods. The resutls we observed were as follows: 1. Alveoli from SO_2-exposed rats (for 5 days) were strongly stained with anti-laminin antibody, suggesting laminin expressed at the high level, at week 1 to 3 upon exposure to SO_2 2. At week 1 to 3 after exposure of rats to SO_2, alveolar septa were collapsed, leading to the reduction of alveolar volume along with morphological changes to irregular shapes. 3. At week 4 to 6 after exposure of rats to SO_2, alveoli were weakly stained with anti-laminin antibody, suggesting laminin expression was decreased during this period. 4. Rats sacrificed at week 7 upon exposure to SO_2 exhibited the expansion of new alveoli and the expression of laminin was partially recovered up to the intermediate level. Taken together, these results demonstrate that the expression of laminin was enhanced in the early phase, followed by downregulation in the late phase. Moreover, lung injury and resolution were correlated with the level of laminin. Thus, these results suggest that SO_2 suppresses the expression of laminin, which may be associated with the neo-generation of lung tissue.
