Low back pain patients an controls of shipyard workers were surveyed between June 1995 and september 1995 to identify risk factors of industrial low back pain. The patients were 17 male workers who had got medical treatment for over 3 days because of industrial back pain controls were 51 male workers who had not have musculoskeletal disorder for one year before the survey. By univariate analysis, the workers who did overtime work 4 times or more for the last 2 weeks showed odds ratio of 3.67 on low back pain with the workers who did less overtime work. Carrying heavy materials was also associated with the low back pain and the odds ratio increased with the increase of carrying weight. work space and work posture were not associated with the low back pain significantly. The welder had higher odds ratio than the other workers on low back pain. The duration of employment and job satisfaction did not affect the risk of low back pain. Multiple logistic regression analysis showed that frequency of overtime work for the last 2 weeks and carrying heavy materials among the risk factors were associated significantly with the low back pain. We found that important risk factors of low back pain of shipyard workers are work intensity factors such as overtime work and carrying heavy weight.

PURPOSE: The purpose of this study was to identify relationships among self-esteem, social support, nursing organizational culture, experience of workplace bullying, and the consequences of workplace bullying in hospital nurses, and then to provide basic information for developing workplace bullying prevention programs. METHODS: Participants were 122 hospital nurses from three general hospitals. Data collection was done during April and May 2015. Data were collected using self-report questionnaires which were used to identify participants' characteristics, self-esteem, social support, nursing organizational culture, and workplace bullying. RESULTS: Approximately one quarter of the nurses had experienced workplace bullying in the past six months. Hierarchical regression analysis showed that experience of workplace bullying (β=.45) and self-esteem (β=-.31) explained 53.3% of the variance in consequences of workplace bullying. CONCLUSION: Based on the findings that experiencing workplace bullying and having a low self-esteem were likely to increase workplace bullying in hospital nurses, there is a need to develop prevention and intervention programs on avoiding or dealing with workplace bullying.

A 52-year-old woman was admitted with a palpable mass on the abdominal wall. This tumor had developed at the same site of a previously resected dermatofibrosarcoma protuberans. The biopsy specimen from the recurrent tumor revealed malignant fibrous histiocytoma. Immunohistochemistry with anti-CD34 antibody revealed diffuse linear positivity on the tumor cells of dermatofibrosarcoma protuberans and negativity on malignant fibrous histiocytoma. Anti CD34 antibody was valuable for a differential diagnosis of these two lesions.

Adenoid cystic carcinoma (ACC) of the breast is an uncommon carcinoma accounting for less than 1% of the breast carcinoma. This type of carcinoma has a distinctive histology, such as cylindromatous, cribriform, glandlike space and solid pattern in the variable proportion. Prognosis is favorable with rare recurrence or metastasis and the guideline for therapy is not well established. We experienced a case of ACC of right breast in the 48 year-old woman. Cytologically, it showed numerous three-dimensional, well outlined cell clusters with central core of homogeneous, eosinophilic material. The mass was well demarcated, firm and measured 2.5 2.5 2 cm. Cut surface was yellowish white and granular with focal necrosis. Histologically, the tumor was composed of cylindromatous, adenoid and solid area with marked cellular atypia. Focal invasion was identified in the adipose tissue around the tumor. Histologic and nuclear grade was III by Kleer's grade. Nodal metastasis was not found.

This study was performed for the comparison of the therapeutic efficiency between 6-month (2tHER/4HER) and 9-month (9HER) short-course chemotherapy under the programe conditions for pulmonary tuberculosis in terms of sputum AFB negative conversion rate, remedial interruption rate and cost effectiveness analysis. Two hundreds and ninty three patients treated with 9HER and 641 treated with 2HERZ/4HER had been discharged from 22 health centers in Seoul from May 1, 1993 to April 30, 1994. Seven hundreds and seventeen was subsequently analysed excluding 217 patients due to remedial interruption. The results: 1. Bacteriological negative conversion rate in 9HER regimen and 2HERZ/4HER regimen was 97.8% and 96.4% respectively (p>0.05). But the early treatment period, negative conversion rate in 2HERZ/4HER regimen was very higher than in 9HER regimen(p<0.01). 2. Remedial interruption rate for 9HER regimen and 2HERZ/4HER regimen was 34.1% and 13.6% respectively. The primary reason for the interruption was transfering to other clinics and this interruption was high within 3months. 3. Cost effectiveness for 2HERZ/4HER regimen was higher than 9HER regimen. The difference cost effectiveness ratio was 2.33 at the first sputum test and 1.69 at the last sputum test.

The expression of the nuclear phosphoprotein p53, a product of tumor suppressor gene, has been noted in a number of human tumors as a tumor suppressor. nm23 is a gene associated with low tumor metastatic potential and has been proposed to be a metastasis suppressor gene. To assess the role of p53 and nm23 expression in colorectal tumorigenesis and the association with clinicopathological parameters, an immunohistochemical study for mutant p53 and nm23 was done using mouse monoclonal antibodies in 43 colorectal carcinomas, 55 tubular adenomas and corresponding normal mucosa. In the tubular adenomas, p53 expression was significantly correlated with the degree of atypism(p<0.05) but not with other variables as well as with nm23. In the colorectal carcinoma, there were evidence of some correlation between metastasis, laterality and p53; laterality, depth of invasion and nm23 expression, but without statistical significance. Other clinicopathologic features were not significantly correlated. In the aspect of 'adenoma-carcinoma sequence', normal mucosa was totally negative for both p53 and nm23, and they were increasingly expressed through tubular adenoma to carcinoma with statistical significance(p<0.05). Therefore, it is suggested that both p53 and nm23 expressions occur in and around the time of transition to carcinoma from adenoma but are not significantly associated with the infiltrative behavior and metastasis.

The purpose of this study was examine the general characteristics of relapsed pulmonary tuberculous patients (i.e. age, sex, weight, occupation, previous forms of treatment, drug sensitivity, and the frequency of relapse) in order to improve future treatments of tuberculosis as well as to perpetuate health education. The data was obtained from the medical records of 186 relapsed pulmonary tuberculosis patients who were registered for treatment at various public health officers in Seoul during the year of 1994. The major findings obtained from the study were as follows; l) The male to female ratio of relapsed pulmonary tuberculous patients was about 7:3, more specifically 23.7% of the men and 30.9% of the women were between 20 and 29 years of age. 2) Comparing initial less aggravated states to relapsed states, patients with minimal x-ray findings later proved moderately advanced X-ray findings. Furthermore, patients with negative sputum AEB findings later proved positive sputum AFB findings. 3) of the l86 patients studied, 91.9% suffered, relapse and 8.1% suffered 2 or more relapses. Of the patients who suffered at least 1 relapse, 54.8% received short-term treatment, 26.9% received long-term treatment, and 18.3% received treatment of an unknown during their initial tuberculosis treatment periods. 4) Fifty five point four percent of the patients had no reaction to the drug treatment(not available), 25.9% of the patients had sensitive reaction to the drug treatment, 18.7% of the patients had resistant reaction to the drug treatment. Drug resistance was higher in patients to exhibited positive X-ray findings as well as in patients that exhibited positive sputum findings furthermore, patients receiving treatment of an unknown nature(35.5%) exhibited higher drug resistance than those receiving short-term treatment(13.6%) and long-term treatment(l7.0%). 5) Of the 160 patients who suffered relapses, 8.8% suffered a relapse within 1 year after treatment and 91.2% suffered a relapse at least 1 year after treatment. Furthermore, our study showed that women, under 30, who received short-term treatment and encounterd complications during their primary treatment suffered relapses faster than any other groups studied. In addition, minimal X-ray findings and sputum AFB findings were not correlated to the time relapse occurred. Therefore, the greater efforts are needed to prevent relapsed pulmonary tuberculosis.

PURPOSE: Despite the well-known public health benefits of vaccination, increasing public concern about the safety of childhood vaccinations has led some parents to refuse or hesitate having their children immunized. The purpose of this study was to identify the subjectivity of parents toward refusal of childhood vaccination. METHODS: Q-methodology, in which subjective viewpoints are explored and analyzed using a combination of quantitative and qualitative techniques, was used. Thirty-five participants were asked to rank 42 statements on diverse issues of childhood vaccination according to a continuous 9-point scale ranging from -4 for strongly disagree to +4 for strongly agree. Collected data was analyzed using the PC-QUANAL program. RESULTS: The results revealed three discrete groups of parents in the refusal of children's immunization: type I, distrust; type II, concern about side effects, and type III, belief that vaccinations are unnecessary. CONCLUSION: Special nurse counselors who can provide correct information about vaccination based on the three types should be part of the government policy. Customized education programs to shift viewpoints should be also redeveloped according to the results in this study.

PURPOSE: The purpose of this study is to investigate the differences Quality of Life(QOL) according to menopausal symptoms in middle aged women. METHOD: The subjects consisted of 578 women(45-60 years old) residing in urban area by convenience sampling from March 15 to May 30, 2002. The data were collected by structured questionnaire that included general characteristics, menopausal symptoms and QOL scale. the collected data were analyzed by the SPSS 11.0 program that included descriptive statistics, t-test and ANOVA. RESULT: The averaged age of menopause of subjects was 48.29 4.66 years and 74.8% in the subjects complained menopausal symptoms. As for the orders of complained menopausal symptom, it was fatigue, hot flashes, benumbed hands and feet, and irritability. The mean score of the QOL scale was showing above average level of quality of life. Religion was significantly different to the score for activity of QOL, monthly income was different to the score for activity and physical well-being of QOL. Menopausal status was significantly different to the QOL. CONCLUSION: This study suggests that a replicate study is needed. The results are also useful in developing various programs for health promotion of middle aged women.

The purposes of this study are to define the scope of occupational health management and to classify occupational management by review of related journals from 1945 to 1994 in Korea. The steps of this study were as follows: (l)Search of secondary reference; (2) Collection and review of primary reference; (3) Survey; and (4) Analysis and discussion. The results were as follows; 1. Most of the respondents majored in occupational health(71.6%), and were working in university (68.3%), males and over the age 40. Seventy percent of the respondents agreed with the idea that classification of occupational health management is necessary, and 10% disagreed. 2. After integration of the idea of respondents, we reclassified the scope of occupational health management. It was defined 3parts, that is, occupational health system, occupational health service and others (such as assessment, epidemiology, cost-effectiveness analysis and so on). 3. The number of journals on occupational health management was 510. It was slightly increased from 1986 and abruptly increased after 1991. The kinds of journals related to occupational health management were The Korean Journal of occupational Medicine(18.2%), several kinds of Medical College Journal(17.0%), The Korean Journal occupational Health(15.l%), The Korean Journal of preventive Medicine(15.l%) and others(34.6%). As for the contents, the number of journals on occupational health management systems was 33(6.5%) and occupational health services 477(93.5%). Of the journals on occupational health management systems, the number of journals on the occupational health resource system was 15(45.5%), occupational finance system 8(24.2%), occupational health management system 6(l8.2%), occupational organization 3(9.1%) and occupational health delivery system l(3.0%). of the journals on occupational health services, the number of journals on disease management was 269(57.2%), health management 116(24.7%), working environmental management 85(18.1%). As for the subjects, the number of journals on general workers was l85(71.l%), followed by women worker, white color workers and so on. 4. Respondents made occupational health service(such as health management, working environmental management and health education) the first priority of occupational health management. Tied for the second are quality analysis(such as education, training and job contents of occupational health manager) and occupational health systems(such as the recommendation of systems of occupational and general disease and occupational health organization). 5. Thirty seven respondents suggested 48 ideas about the future research of occupational health management. The results were as follows: (l) study of occupational health service 40.5%; (2) Study of organization system 27.1%; (3) Study of occupational health system (e.g. information network) 8.3%; (4) Study of working condition 6.2%; and (5) Study of occupational health service analysis 4.2%.
