In the current situation in which any effective treatment or preventive vaccine for AIDS has not yet been invented, the most important method of control to reduce the chances of HIV infection is through the continuous education about AIDS. Hospital workers are one type of group which are at a high risk for HIV infection and to some degree resposible for the transmission of AIDS.

This study was conducted to investigate the predictive validity of self-perceived health status or the medical examined health level by health related practices. This study surveyed 18,873 people aged 50 and over by the data from a health insurance institute. We analyzed the self-evaluation questionnaires concerning health related practices and self-perceived health status which each individual filled out. We compared these with data concerning health levels produced by medical examinations. As for the health related practices, 9 variables such as dietary habits, smoking, drinking and exercise were surveyed. We applied discriminant analysis to predict the self-perceived health status and related it to professionally examined health level by health related practices. As for self-perceived health status, the accuracy of the prediction rate was 79.4%, as for the healthy group : 80.9% and specificity for unhealthy group : 55.5%. As for the medical examined health level, the total prediction rate was 56.2%, as for the normal group : 58.8% and specificity for the abnormal group : 53.4%. The result of this study indicates that health related practices were able to predict the self-perceived health status to a high degree, but not the health level by professional medical practices.

In order to find out the positive rate of surface antigen of hepatitis B virus (HBsAg) in the industrial workers and to study the association with liver disease, a total of 2,579 workers in an industrial establishment was selected and evaluated. During the three months from June 1985, a screening test detecting HBsAg was conducted by reverse passive hemoagglutination method (RPHA method) and factors related to hepatitis B virus infection were studied through the questionnaire survey. The results of the examination were as follows; 1. The positive rate of HBsAg was 7.5%; male 8.1%, female 6.0%; production line workers 7.8%, office workers 6.5%. But, there were no statistical significance between the two rates. 2. The occurrence rates of HBsAg in the workers who have a long working experience in the plant and elders were turned out to be bit higher. Workers with middle school education background showed higher rate. 3. It was confirmed that the positive rate of HBsAg was related to history of medical treatment for the industrial accident, past history or family history of liver disease, particularly mothers' past history. 4. It was also learned that the positive rate of HBsAg was related with skin test for liver or lung flukes and drinking habit. 5. No significant difference was found in positive rate amongst the persons who have had experiences in acupunctural, blood transfusion, sexual intercourse with prostitutes, injury caused by nail cutting or shaving at the harbor shop.

Under the pressure to open the service market as proposed by World Trade Organization, we can easily expect our educational systems for allied health professions will experience a lot of changes in near future. Accordingly, we compared our current educational systems for allied health professions with the foreign ones and mapped out some strategies predicting the forthcoming enormous changes. Major investigations and analysis are summed up as follows, The educational programs for allied health professions which was started in 1963 in Korea are stilled remained as 2 to 3 school years, while the systems in advanced countries have already been changed or been changing from 2 year to 4 year college levels. We can hardly find the uniform educational system or school years for the allied health professions in the world except for Korea. Fortunately, university level four-year programs for the profession was established in 1979 in Won-joo for the first time in Korea. However, there are still only few four-year programs in this country. To meet the rapidly changing needs we have faced in the health areas we should supply appropriate health personnel through various efforts. Now we would like to suggest followings, <Educational goals for the allied health professions> 1) reconfirming characteristics for the educational goals of health professions 2) extending school years for the allied health professions 3) strengthening clinical training and internship 4) expanding opportunities for the continuing education through lifelong education 5) upgrading from old-fashioned technologies to advanced technologies 6) cultivating competencies of health professionals for the global competition <Suggestions for the Development of Allied Health Professions> 1) reforming the school years of educational programs for the allied health professions to meet the global standards 2) expanding the role of junior college programs for the allied health professions through the development of intensive courses in the professions. 3) diversifying and specializing the allied health professions mainly through 4 year B.S. degree programs.

This study was attempted to identify trends and determinants of the profitability of Korean Provincial Hospitals different. Data used in this study were chosen from provincial hospitals that passed the standardization audit undertaken by the Korean Hospital Association from 1998 to 2001 for the purpose of accrediting training hospitals. There were collected from 19 provincial hospitals with complete general data of present conditions as well as financial statements(balance sheets, income statements). The dependent variables in this study were used net profit to total assets and operating profit to gross revenue as a proxy indicator for profitability. The independent variables were classified by general factors(location, teaching status, number of beds, period of establishment), operating and financial factors(current ratio, fixed ratio, liabilities to total assets, total asset turnover, average length of stay, bed occupancy rate, admission ratio of outpatients, patients per specialist, personnel costs per adjusted inpatient, material costs per adjusted inpatient, administrative costs per adjusted inpatient), in addition time leg effect(fiscal years). As a result of hierarchical multiple regression analyzation of net profit to total assets and operating profit to gross revenue, with general factors, operating and financial factors, adjusted R² of operating and financial factors is very powerful. The factors had significant positive effect on net profit to total assets were period of establishment, current ratio, admission ratio of outpatients. The factors had significant negative effect on net profit to total assets were average length of stay, personnel costs per adjusted inpatient, fiscal years. The factors had significant positive effect on operating profit to gross revenue were teaching status, fixed ratio, total asset turnover. The factors had significant negative effect on operating profit to gross revenue were location, liabilities to total assets, personnel costs per adjusted inpatient.

An investigation was conducted to assess the chemopreventive effects of chitosan in a rat preneoplastic colorectal carcinogenesis induced by azoxymethane (AOM). Thirty, 5-week-old, male F344 rats were divided into three groups. CRF-1 diet containing 2% chitosan and control diet were fed to the rats of group 1 and 2, respectively, for 12 weeks. AOM (15 mg/kg body weight, subcutaneously) were given to the rats three times for 2 weeks from week 2. The treatment regimen to the rats of group 3 were same to the group 1 except that saline was given instead of AOM initiation. Animals were sacrificed at week 12 to examine the development of aberrant crypt foci (ACF). A decreasing tendency was observed in the total number of ACF and sum of aberrant crypts in group 1 comparing with those of group 2. These results indicate that chitosan may have inhibiting effects to the development of preneoplastic lesions by azoxymethane and be a potential chemopreventive food component.
