The use of food frequency questionnaire to estimate dietary intake has become widespread in epidemiologic studies. It has been suggested that knowledge about a person's usual serving size of each food, in addition to consumption frequency, will improve the accuracy of this method. This sutdy was performed to investigate the nutritional status and one serving sizes of commonly consumed dishes in Korean college women. Intakes of dish or food in 156 college women were measured by 7-day wiighed food records in May, 1992 and May, 1993. For each dish or food, variance in one serving size was partitioned into within-person(intraindividual) and between-person(interindividual) components. All nutrient intakes except vitimin A and vitamin C were less adequate. The jamor dish groups which contributed to the most daily nutrient intakes were boiled rice, bread, fruits, dairy product, and biscuit and snack groups. In more than 50% of dishes, the within-person variation was greater than between-person variation. And the variety and amount of food which was used in one dish were too variable to make standard recipe.

The purpose of this experiment is to investigate conservation of tocopherol in edible oils during storage. The dietary oils used in this study were soybean oil, corn oil, repeseed oil, perilla oil, sesame oil and one portion of each was kept at room temperature while another was in refregerator. The contents of total tocopherol in vegetable oils were in the order of corn oil, soybean oil, perilla oil, sesame oil, repeseed oil. Tocopherol content of soybean oil and corn oil were not different significantly bystorage condition, but those of repeseed oil, perilla oil and sesame oil were 30~50% higher when oils were stored in the refregerator than those kept at room temperature. Tocopherol in sesame oil was best conserved, when oil was kept refregerator, since the decrement was less than 10%. Therefore, it is recommended that perilla oil, sesame oil, repeseed oil be keptin refrigerator. These results suggest peroxide formation in oils is repressed both by low temperature and higher content of tocopherol conserved in oils by refrigeration.

The objective of this study was to investigate the managing realities of EVD and provide a descriptive survey with the attempt to obtain basic data needed for the standardization of EVD management. For that purpose, 220 questionnaire copies were distributed to those nurses who were working with intensive care units at university hospitals, general hospitals, semi-general hospitals in Seoul, Kyongki-de and local areas. Of 158 returned questionnaire copies, 139 were used for analysis. Data were collected during the term of academic seminars of Neurosurgery Nursing Committee and KICA (Korea Intensive Care Association), ranging from Oct. 26 through 27. 2000. The tools utilized a structured questionnaire form consisting of 21 questions on general characteristics, the level of understanding, the level of work performance, standard management guidelines, etc. The data collected were analysed with frequency, percentage, mean vague, chi -square test using the SPSS 10.0 program Findings were revealed, as follows: For managing the prevention of EVD infection, aseptic technique was found to be of the most importance (48.9%),'the technique should be carried out at an operation room'(92.8%), but it was actually performed at intensive care units (over 51.5%). 'The term of antibiotics use should be less than 7 days' (81.8%), while it was actually executed for less than 7 days (49.5%). 'The proper time of quittance from it should be within less than 7 days'(74.1%) but actual quittance was executed only by 51.1%. 'Set exchange is needed' by 54.0% but actual exchange was implemented merely by 28.1%. 'The subject of management should be nurses' was reflected by 40% but actually 52.0% were carried out. As a result of hating analysed the understanding of the management of EVD by general characteristics, a significant difference was found in the necessity for set exchange by hospitals, in the time of quittance of a catheter, and in ablution items by work experience. The result of hating analysed the work performance levels of EVD management by general characteristics revealed that a significant difference in administration facilities of medicine by the classification of hospitals, especially the use of antibiotics and the quitting time of a catheter by the classification of intensive care units, and in the use of antibiotics and ablution items by the standard management guidelines.

2,3,7,8-Tetrachlorodibenzo-ρ-dioxin (TCDD) is a ubiquitous, persistent environmental contaminant and the most powerful carcinogen categorized by IARC. Although the mechanism of carcinogenesis by TCDD is poorly understood, several studies have shown that the skin is one of target organs for TCDD. In this study, we investigated the neoplastic transformation of human keratinocyte-derived cell line, HaCaT, by chemical transformation method using N-methyl-N'-nitro-N-nitorsoguanidine (MNNG) and TCDD. We found that subsequent exposure to TCDD for 3 weeks after initial exposure to MNNG markedly induced transformed cells. It was suggested that TCDD can act as a potent promoter in HaCaT cells. Furthermore, these transformed cells showed morphological alternations in soft agar and increased telomerase activity. Therefore, the TCDD treatment of HaCaT cells by initiated with MNNG could promote neoplastic transformation without stimulation by exogenous growth factors. As a result, TCDD had a strong potency as a promoter in nontumorigenic immortalized human epidermal keratinocytes.
