Cytokeratin 7 has been known to be present in various types of human epithelial cells including the ovarian neoplasms, but not in colon cancers. The antibody to colon ovarian tumor antigen (COTA) has been introduced as a marker of colon and ovarian tumors. The aim of this study was to evaluate the usefulness of cytokeratin 7 and COTA in the differential diagnosis between ovarian primary and metastatic tumors. Nineteen primary ovarian epithelial tumors, seven metastatic carcinomas of the ovary from the stomach, three metastatic carcinomas of the ovary from the colon, one mucinous tumor of the ovary associated with a mucinous tumor of the appendix and pseudomyxoma peritonei, and nineteen colonic and twenty gastric adenocarcinomas were stained with monoclonal antibodies to cytokeratin 7 and COTA. The results are summerized as follows; In the primary ovarian tumors, 94.4% were positive for cytokeratin 7 and 50% were positive for COTA. In the primary colonic adenocarcinomas, 94.7% were negative for cytokeratin 7 and 68% were positive for COTA. In the metastatic ovarian tumor from the colonic adenocarcinomas, 100% were negative for cytokeratin 7 and positive for COTA. In the primary gastric adenocarcinomas, 40% were negative for cytokeratin 7 and 85% were negative for COTA. In the metastatic ovarian tumor from the gastric adenocarcinomas, 43% were negative for cytokeratin 7 and 14% were negative for COTA. From the results of this study, it could be concluded that in the differential diagnosis of primary ovarian tumors from metastatic colonic carcinomas, positive reaction for cytokeratin 7 suggests a primary ovarian tumor but a negative reaction for cytokeratin 7 and positive reaction for COTA suggest metastatic colonic carcinomas. The results of this study also reveal that cytokeratin 7 and COTA are not useful in the differential diagnosis of primary ovarian tumors from metastatic gastric carcinomas.

Service diversification is recognized as an important strategy against turbulent environmental change. This study is designed to find out the trend of service diversification in Korean health care organizations and also to identify factors associated with the degree of service diversification. Data were collected from 69 hospitals out of 71 hospitals with over 300 beds. Important findings are summarized below. 1. Types of diversification are closely related to hospital size. Large hospitals have a tendency to provide sophisticated service requiring specialized skills and equipment, while small hospital have concentrated their efforts on health screening programs. 2. The more competitive and bigger hospitals are, the greater number of services that provide. Also, hospitals operating rational management information systems provide more services. Contrary to the expectation, hospitals with a low performance during last 3 years showed more service diversification. 3. A trend of more diversification was observed in hospitals whose chief executive officer used a prospector strategy. 4. A multiple regression analysis revealed that bed size, competitive environment, degree of rational management, and the growth pattern were significantly associated with teh service diversification.

There are increasing interest and need for information on health care consumer with the significance of hospital marketing and strategic planning being increasingly emphasized. This study was conducted to investigate the criteria for selection of medical facilities according to the characteristics of health care consumer by the types of medical services on a sample of 1,500 population aged 20 years and above. Major findings are as follows; 1. When considering the criteria for selection of medical facilities into two factors, namely, quality or convenience factors, convenience factor was the major contributor for outpatient and dental services whereas it was quality factor for inpatient services. 2. Females and those residing in large cities selected medical facilities based on convenience factor in the outpatient services. In the case of inpatient service, persons who considered their present health status to be good and whose ages were 50 years old and above choose medical facilities based on quality factor. 3. Persons who considered medical facilities to be profit-making tended to choose medical facilities based on convenience factor for outpatient services. There were no differences in the cases of inpatient and dental services. 4. There was no significant difference on the criteria for selection of medical facilities according to the decision maker for selection or trust on medical facilities. On the use of health service information, selection of medical facilities was based on qPality factor for those who made more use of the information in the cases of outpatient and dental services. 5. Analysis using the logistic regression model on the criteria for the selection of medical facilities with the characteristics of health care consumer as independent variables was performed. The selection of medical facilities was significantly related with residential area, sex, and use of information on medical facilities for outpatient services and with age, average monthly income, and perception of health status for inpatient services. For dental services significant association with residential area and use of information on medical facilities was seen. The results of this study, despite some limitations, can be used as baseline data for marketing and strategic planning of hospital management.

Alternaria cassiae Jurair & Khan was recorded on seeds of sickle senna(Cassia tora L.). Seed infection ranged from 25~45% in two samples. Developing roots and shoots turn brown and died in case of severe infection. Detailed descriptions were given on the habit characters of the fungus and on the morphology of conidiophores and condia. This is the first report of A. cassiae on seeds of Cassia.
