This study was carried out to evaluate the relations among workers' general characteristics, work-related behaviors and health related behaviors in a steel industry with 1,134 workers in Pohang. The results were as follows; 1. The mean age of workers was 50 years old and working duration was 15 years and over. Most of them were married(94 5%) and had studied beyond high school (53.0%). They performed three shift work and most of them(63.0%) had experienced industrial accidents. The frequency of noise and dust exposure was defined by a minimum of 6 hours per day, and workers complained about noise exposure(62.9%) and dust(55.6%). There were current smokers(67.7%), current drinkers(74.3%) and current exercising workers(32.3%) in the industry. The number of cigarette consumption in current drinkers was significantly high (13.6 +/- 8.4 pieces/day) and the alcohol consumption in current smokers was significantly high(l04.5 +/- 113.5 g/wk). And the number of cigarette consumption of exercisers was significantly low and the alcohol consumption of exercisers was higher than non-exercisers. 3. The ratio of current smokers on frequent noise in exposed workers versus non-exposed workers was not significantly high but the current drinkers in frequent noise and dust exposed workers was significantly higher than non--exposed. 4. The normal levels of SGOT workers in non-smokers were significantly higher than in current smokers, and the abnormal levels of LFT(SGOT, SGPT, gamma-GTP workers in nondrinkers were significantly high. The normal levels of SBP and DBP workers in current smokers were not significantly high but were significantly high in non-drinkers. 5. The ratio of current smokers in workers unsatisfied with their job and working condition was higher than non-smokers, but the ratio of current drinkers in workers satisfied with their job and working condition were higher. 6. The significant factors for SGOT and gamma-GTP were age, the drinking amount and BMI. But the only significant factor for r-GTP was BMI. The significant factors for DBP were age, the alcohol consumption and BMI And the significant factors for SBP were age, BMI.

BACKGROUND: Through the control of tuberculosis at 22 public health centers under the National Tuberculosis Control Program, this study is purposed to examine the situation of the tuberculous patients and the characteristics of the therapeutic regimens. METHODS: The data was obtained from 8091 medical records of pulmonary tuberculous patients who were registered for treatment at public health center in Seoul during the year of 1993. It was comparatively analysed by the general characteristics(gender, age, chest X-ray findings, sputum results, treatment results, side effects, combined diseases and accompanied extra-pulmonary tuberculosis) according to various regimens of the tuberculosis. RESULTS: The male patients were 5144, the female were 2947. 34.1% of patients were between 21 and 30years of age. Short course regimen was 97.1% and long course regimen was 2.9%. According to chest X-ray findings minimal 53.5%, moderately advanced 41.2%, far advanced 5.3%. Sputum AFB negative was 52.2% and positive was 47.8%. Therapeutic efficiency was high in short course regimen. Among the side effects, dermatologic problems was high and at the regimen of EHRZ side effects were developed highly. Combined diseases were liver diseases(5.2%), DM(4.2%). Accompanied extrapulmonary tuberculosis were pleurisy(5.4% ), superficial lymphadenitis(0.4% ). CONCLUSIONS: There was great effects in the treatment of tuberculosis with short course regimen in the National Tuberculosis Control Program. But only 38% among the expected patients were treated in this country. So the greater efforts were needed to find and treat more patients effectively.

OBJECTIVES: Cord blood stem cells have been widely used as donor cells for bone marrow transplantation recently. These cells can give rise to a variety of hematopoietic lineages to repopulate the blood. Recent observations reveal that some bone marrow cells and bone marrow stromal cells(MSCs) can grow to become either neurons or glial cells. It is, however, unclear whether or not there exists stems cells which can differentiate into neurons in the blood during the early stages of postnatal life. METHODS: Human cord blood stem cells were prepared from human placenta after full term delivery. To induce neuronal differentiation of stem cells, beta-mercaptoethanol was treated. To confirm the neuro-glial characteristics of differentiated stem cells, immunocytochemical stain for NeuN, neurofilament, glial fibrillary acidic protein(GFAP), microtubule associated protein2(MAP2) was performed. RT-PCR was performed for detecting nestin mRNA and MAP2 mRNA. RESULTS: We showed in this experiment that neuro-glial markers(NeuN, neurofilament, MAP2, GFAP) were expressed and axon-like cytoplasmic processes are elaborated in the cultured human cord blood stem cells prepared from new born placenta after full term delivery. Nestin mRNA was also detected in fresh cord blood monocytes. Conclusions: These results suggest that human cord blood derived stem cells may be potential sources of neurons in early postnatal life.

PURPOSE: This research was conducted to explore the experiences of graduate student women with children fulfilling multiple roles and to generate a substantive theory. METHODS: This study uses the grounded theory method based on Strauss and Corbin(1988)'s method. Interviews were conducted with 11 graduate student women who had children aged three of older. RESULTS: The core category of this research is 'Role balancing for self-generativity'. Based on the core category, three types of married women graduate students' experiences were found. They are 'concentrating on graduate-work' 'postponing graduate-work' and 'adjustment between two roles' CONCLUSIONS: Through understanding the married women's multiple roles experience process, there can be a basis for making a women's health system and social support system for the married women graduate student. Also, this research is to generate a substantive theory which can helps to change social perspectives on the quality of life for the women who will contribute in Korean society as professionals.

The purpose of this study was to evaluate weight control program provided by university health care center for female college students. The program was 8-week long and composed of diet, exercise, and behavioral modification. Evaluation was made on the completion of 8-week program and a follow-up survey was done at 3 - 24 months after the end of program by telephone or by e-mail. Total of 76 women completed the 8-week program and 51 for follow-up survey. On the completion of 8-week program, significant decreases in body weight, BMI, body fat (kg), % body fat, and WHR were resulted, however, no change in muscle mass was found. Even the subjects without weight change showed significant reduction in body fat (kg) and % body fat. Total food intake was decreased resulting in reduced intakes of most nutrients. Meal distribution of energy was changed; %energy from snack decreased from 22% to 14%, and proportion for breakfast increased. Blood values of hemoglobin, hematocrit, total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride were within normal range, and no changes were observed by this program. The follow-up survey revealed that 88.3% of the subjects continued to lose weight after completion of the program, while only 7.8% gained weight. And 78.4% of the subjects considered the program effective. In conclusion, the weight reducing regime with education is effective for long lasting weight control and health conscious behavior for female college student. Since the subjects reduced the size of meal, instead of cutting only calories down, food selection to meet all the nutrient requirements except energy should be emphasized.

BACKGROUND/OBJECTIVES: The purpose of this study is to analyze daily kimchi, vegetable and fruit consumption by general characteristics and vegetable and fruit consumption from 1998 to 2012 by the Korean population based on the data of the KNHANES (Korea National Health and Nutrition Examination Survey). SUBJECTS/METHODS: This study is based on the 1998-2012 KNHNES. Analysis data on 54,700 subjects aged 19 years and older were obtained from health behavior interviews and the 24-hour dietary recall method. RESULTS: Daily kimchi consumption and portion size of kimchi decreased significantly from 1998 to 2012 (adjusted P for trend < 0.0001). Meanwhile, daily consumption of both non-salted vegetable and fruit with and without kimchi did not significantly change between 1998 and 2012. Reduced consumption of kimchi, non-salted vegetable, and fruit was observed for both genders as well as daily meal episodes and cooking locations. Male and female subjects with insufficient non-salted vegetable and fruit intake were increased 1.4 times and 1.3 times, respectively, in 2012 than 1998. All subjects consumed at least 400 g/day of non-salted vegetable, fruit, and kimchi in each survey year, although they consumed insufficient amounts (< 400 g/day) of non-salted vegetable and fruit without kimchi. CONCLUSIONS: Since Koreans generally consume high amounts of fermented vegetables, including kimchi, total vegetables and fruit. Consumption of these foods by the Korean adult population reached 400 g, which is the recommended intake of the WCRF/AICR. Based on this result, it is necessary to promote consumption of kimchi in the Korean population and research the development of low sodium kimchi in the future.

Ovarian hyperstimulation syndrome is a serious complication of ovulation induction and has a diverse clinical spectrum from edema to thromboembolism. Antiphospholipid antibody syndrome, one of the well known hypercoagulable states, can be also manifested as an arterial or venous thrombosis and recurrent spontaneous abortion. Sometimes a patient with antiphospholipid antibodies might not notice a miscarriage and seek for assisted reproduction treatment, which harbors a chance of developing ovarian hyperstimulation syndrome. If this happens, the ovarian hyperstimulation syndrome can exacerbate the thrombotic complication of underlying antiphospholipid antibody syndrome, resulting in a catastrophic vascular event. The authors experienced a case of middle cerebral artery infarct, which developed during ovarian hyperstimulation syndrome in a 33-yr-old woman with a previous history of fetal loss. An elevated titer of anticardiolipin antibodies was noticed and persisted thereafter. The authors suggest screening tests for the presence of antiphospholipid antibodies before controlled ovarian hyperstimulation.

PURPOSE: Hepatocellular carcinoma (HCC) is one of the most common cancers in many parts of the world, however the molecular mechanisms underlying liver cell transformation remain obscure. The instability of microsatellite sequences dispersed in the genome has been linked to a deficiency in cellular mismatch repair. This phenotype has been frequently observed in various human neoplasms and is regarded as a major factor in tumorigenesis. To investigate cumulative genetic changes related with apoptosis during development and progression of HCC, we examined DNAs isolated from 12 Korean HCCs and their adjacent non-tumorous parts to look for evidence of microsatellite instability (MSI). MATERIALS AND METHODS: Twelve microsatellite loci (D6S271, D6S426, D13S153, D13S263, D17S849, D17S938, D17S945, D18S474, D18S64, D19S420, D.19S418 and D19S210) were amplified by PCR from 12 Korean HCCs, and analyzed using an automated DNA analyzer. RESULTS: The high percentages of the MSI were found for the loci of D6S426 (33.3%) and D17S945 (25.0%). The related genes with high frequency of MSI were noted in the wafl (41.7%) and p53 (25.0%). From this study, fifty eight percent of HCCs (7/12) showed MSI with at least one marker. CONCLUSION: This results suggest that the analysis of MSI in HCC might be useful for identifying genes whose loss of function contributes to the development of liver cancer. Furthennore, this method may give a more rapid and accurate sizing of the PCR products of microsatellite; making the routine assessment of MSI possible in many clinical fields.

PURPOSE: This study was conducted to explore the professional identity of elementary school health teachers. METHODS: In-depth interviews with fifteen elementary school health teachers were conducted from July 2010 to August 2012. Qualitative data collected by the researcher including transcription and field notes were analyzed through an adapted methodology based on the Grounded Theory of Strauss and Corbin. RESULTS: Fifteen categories, 35 sub-categories and 120 concepts were obtained. The key category that was consistently maintained in identity formation was 'keeping themselves being a teacher providing nursing' which has three styles, 'focusing on health education', 'combining nursing and education' and 'focusing on providing nursing care'. CONCLUSION: Results of this study will provide basic information for preparing manuals regarding the range of activities in school health teachers' jobs, improving promotion and merit payment systems for school health teachers, creating support programs for them, and contributing to the formation and establishment of their professional identity.
