The domestic development status of Inductively Coupled Plasma (ICP) simulator which is based on fluid model is explained. As each part which composes the unified simulator, electron heating module, charged and neutral particle transport module, surface reaction module including a sheath model, and GUI (Graphic User Interface) with pre- and post-processors are described in order. Also, we present data base status of chemical reaction and physical collision, which has been applied to the recently developed simulator until now. Lastly, some future plans of development are suggested.

The objective of this study was to find out the present status of the physio - therapeutic facilities in oriental hospitals The material were used in this study The literatures or annual reports of 15 oriental hospitals which present the status of input resources of physio-therapy departments and performances, Major findings of this study were as follows The average scale of input resource of physio-therapy departments are in difference among hospitals a) number of rooms : 4.5 in average(5.1 in university hospitals, 3.5 in other hospitals) b) size of therapeutic facility' area : $20.0m^{2}$ in average($19.3m^{2}$ in university hospitals, $20.3m^{2}$ in other hospitals) c) number of therapists : 8.6 in average(9.3 in university hospitals, 7.5 in other hospitals)

Purpose: The purpose of this study was to provide the basic techniques in utilizing the systematic home-rehabilitation service with a Minimum Data Set for Home Care (MDS-HC) 2.0 navigator system. Methods: The present study was conducted with 50 persons receiving home-care services from a Welfare Center. Respondents were selected from urban and rural areas in and around the Wonju area. Results: The results showed that MDS-HC2.0 was useful to evaluate the functional status of disabled persons in the fields of health and home-care services. Furthermore, this navigator system provided basic information about the functional health problems of respondents and therefore can provide guidance for health and home care services for disabled persons. Conclusions: Through the present study, a comprehensive model for health and home-rehabilitation was developed. The author believes that respondents will have the satisfaction of high quality service if the developed model is used as the standard in planning and providing home-rehabilitation services.

The purpose of this study is to investigate the present status of environmental education administration in the middle schools of Seoul City and to find problems to be solved environmental education in middle schools. To accomplish these purpose surveys for middle school teachers in Seoul was conducted, and evaluation reports of school environmental education of 1998 were analyzed. The results indicated that both schools and Ministry of Education offered few evaluation standards related to environmental education. Most schools abolished division of environmental affairs because of the reorganization of school system, which focuses on subject and aptitude-based education. In addition, environmental education and related activities were maily the responsibilities of division of science education. The teachers responded that such activities as organization and management of mothers'social service, management of environment day, use of environmental conservation card, and establishment of conservation area were not effective and should be abolished. The conclusion from this study are that environmental education can be effective only when goals of environmental education are included in school evaluation, and the division of environmental affairs should be revived and systematically operated in school.

The present study aims to investigate the feasibility of using a simple nonlinear acoustic method for the assessment of bone status and osteoporosis in trabecular bone. Correlations of linear and nonlinear ultrasound parameters with the apparent bone density were obtained in 32 bovine femoral trabecular bone samples. Highly significant positive correlations were observed between the apparent bone density and the two linear ultrasound parameters, the speed of sound (SOS) and the normalized broadband ultrasound attenuation (nBUA), with Spearman's correlation coefficients of r = 0.85 and 0.77. In contrast, the apparent bone density was found to be negatively correlated with the nonlinear ultrasound parameter introduced in the present study, the logarithmic difference between the power spectrum levels of the fundamental frequency and the second harmonic (PSL1-PSL2), with the highest correlation coefficient of r = -0.92. These results suggest that the PSL1-PSL2, in addition to the SOS and the nBUA, may be useful for the assessment of bone status and osteoporosis.

Objectives: The study aimed to investigate the relationship between depression and number of present teeth in Korean elderly individuals. Methods: Data for this cross-sectional survey was obtained from the records of the sixth Korea National Health and Nutrition Examination Survey (KNHANES). The subjects were 1,199 Korean elderly individuals above 65 years of age. The survey and examination data were used for the independent variables. The KNHANES included health status, nutrition survey, and oral examination. $x^2-test$ was performed to identify the characteristics of depression and number of teeth present according to the characteristics of the study subjects. Logistic regression analysis was also performed to identify the relationship between depression and number of teeth present. The statistical significance level wa sset at 0.05. Results: The prevalence of depression in the subjects was 14.8%. There were statistically significant differences in the prevalence of depression, depending on gender (p<0.001), education level (p=0.001), income (p=0.001), spouse status (p<0.001), and alcohol consumption (p=0.020). The association between depression and the number of teeth present showed statistically significant difference after adjustment (p=0.040). Conclusions: Depression in elderly individuals was closely related to the number of teeth present. Therefore, public health policies for improving oral health should be established to prevent depression.
