OBJECTIVES: This study was intended to investigate the differences of job stressors between managers and low level employees among white-collar workers. Another objective of this study was to examine whether the effects of job stressors on mental health differ between the two groups. METHODS: Data was obtained from 204 managers and 251 low level employees who were employed in white-collar jobs. Fourteen job stressors and seven job stress variables were measured. RESULTS: Among the 14 job stressors, role overload, job insecurity, and work-family conflict were higher job stressors for the manager group whereas role conflict, work-aptitude incongruity, participation in decision making, and promotion problems were higher job stressors for the low level of employees. There were no differences in job stress scores between the two groups. However, differences in the effects of job stressors on job stress were found between the two groups. For the manager group, job insecurity, work-aptitude incongruity, and work-family conflict significantly affected in explanation of job stress whereas for the low level employees, role underload, peer satisfaction, and environmental problems significantly explaining the job stress variables. CONCLUSIONS: There were significant differences in job stressors between managers and low level employees among white-collar workers. Additionally there were differences in the effects of job stressors on job stress between the two groups.

Mural nodules in ovarian mucinous tumors, whether benign, borderline, or malignant, have been described by several authors since Prat and Scully first described sarcoma or sarcoma-like mural nodules occurring in association with mucinous epithelial neoplasia in 1979. Three distinct types of the mural nodule have been identified; i. e., 1) sarcoma-like lesion, 2) true mesenchymal sarcome, and 3) anaplastic carcinoma simulating a sarcoma. Mural nodules of sarcomatous and carcinomatous foci associated with mucinous ovarian tumors should be separated from sarcoma-like nodules because of the poor prognosis of the former compared to the favorable prognosis of the latter. We experienced a case of ovarian mucinous cystadenocarcinoma with sarcoma-appearing mural nodule of anaplastic carcinoma occurred in a 59-year-old woman and reported with brief review of the literatures.

PURPOSE: To explore the dose-response relationship between amount of cigarette smoking and blood lipids and sugar METHODS: In this cross-sectional study, we gathered the smoking history by self-administered questionnaire between 1994 and 1998 among 2888 men who visited the Health Promotion Center at St. Mary's Hospital, Seoul. RESULTS: Adjusted for age, body mass index, the odds ratio of hypercholesterolemia (> or =240 mg/dl) were 2.06 (95% Confident Interval, 1.44-2.94), 2.03(95% CI 1.31-3.11), higher LDL-cholesterol(> or =160 mg/dl) were 2.06(95% CI 1.43-2.98), 2.25(95% CI 1.45-3.45) among group of men who smoked 21-30, over 30 cigarettes per day respectively compared with nonsmokers group. And adjusted for age, body mass index, the odds ratio of lower HDL-cholesterol(<35 mg/dl) were 1.76(95% CI 1.34-2.33), 1.98(95% CI 1.39-2.81), 2.35(95% CI 1.54-3.54), hypertriglyceridemia(> or =200 mg/dl) were 1.93(95% CI 1.47-2.55), 2.57(95% CI 1.82-3.62), 2.80(95% CI 1.86-4.21) among group of men who smoked 11-20, 21-30, over 30 cigarettes per day respectively compared with nonsmokers group. The adjusted odds ratio of diabetes(FBS> or =126 mg/dl) was 1.86(95% CI 1.10-3.06) only among who smoked more than 30 cigarettes compared with nonsmokers. CONCLUSION: This study showed that there were dose-response relationships betwen amount of cigarette smoking and total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride and sugar. It suggested that health promotion program including quitting and decrease of cigarette smoking would be necessary to prevent cardiovascular disease in Korean men.

OBJECTIVES: This study is to evaluate the awareness, attitude, practice and the countermeasures against passive smoking in Korean adults. METHODS: By self-administered questionnaires, we assessed the knowledge, attitude, behavior for passive smoking and the countermeasure for reduction of it's harmful effects in 289 men and 238 women. RESULTS: The subjects that have heard about passive smoking were 96.8% in total and well known were 26.4% of current smoker, 56.6% of ex-smoker, and 14.8% of non-smoker(p=0.001). The irritative symptom from passive smoking was the most frequent in non-smokers and the most common place where exposed to passive smoking was public place. For attitude against passive smoking in 'no smoking allowed area', ex-smokers were the most active to recommend to stop smoking. And for opinion about establishment of 'no smoking allowed area', the restriction by law was the best acceptable method in smokers, exsmokers, and nonsmokers. In marking of 'no smoking allowed area', 69.9% of smokers answered no smoking, but in non-marking area only 6.3% stop smoking. When smokers were recommended to stop smoking, the more subjects stop smoking with good feeling in marking area, but the less in non-marking area. The factor associated the high awareness of passive smoking were aged(OR=1.07, 1.03-1.12), men(OR=4.34, 2.32-8.46). The persons who have known well about passive smoking had good attitude and behavior to prevent of harmful effect of passive smoking. CONCLUSIONS: This study suggested that education program would be necessary to reduce the passive smoking.

OBJECTIVES: This study was conducted to evaluate the risk factors associated with cardiovascular disease. METHODS: By the questionnaire, the informations of education level, monthly income, alcohol consumption and smoking habit were obtained. Height, weight and blood pressure(BP) were measured by a trained nurse. The level of fasting blood sugar(FBS), total cholesterol, hight-density lipoprotein(HDL) cholesterol and triglyceride were tested by enzyme method about a group of 2888 males and 1696 females ages over 20 who had never taken the medication for hypertension. Statistical analysis, ANOVA, stepwise multiple regression, correlation analysis were performed using SAS package program. RESULTS: There were significant differences among age groups in systolic and diastolic blood pressure, body mass index(BMI), FBS, triglyceride and cholesterol except HDL-cholesterol. The risk factors associated with systolic and diastolic BP significantly in male were BMI, age, alcohol intake, but in female BMI, age. Smoking habit had a significant negative correlation with BP in both sex. In the group of mild hypertension (> or =140 mmHg or> or =90 mmHg defined by JNC-VI) and hypertension (> or =160 mmHg or > or = 95 mmHg defined by WHO), the percent of diabetes (FBS> or =140 mg/dl), hypercholesterolemia (> or =240 mg/dl), and hypertriglyceridemia (> or =200 mg/dl) were signifcantly higher compared with normal group in male and female. BMI, and alcohol consumption had a positive correlation with FBS, total cholesterol and triglyceride. Smoking had a positive correlation with cholesterol and triglyceride but negative correlation with HDL-cholesterol in male. The educational attainment had a negative correlation with BMI, FBS, total cholesterol and triglyceride in female. CONCLUSIONS: This study suggested that drinking, smoking, and BMI and lower educational level were associated with hypertension, hyperlipidemia and diabetes, but further evaluation was needed by prospective intervention study.

BACKGROUND: The smoking rate of Korean male workers is top in the world. To establish the effective smoking cessation strategy, we conducted a study to evaluate the factors associated with smoking and smoking cessation. METHODS: We surveyed 509 male workers in a university hospital about age, marital status, drinking, exercise level and checked their awareness and seriousness for diseases due to smoking, benefits from smoking cessation, motivation derived from massmedi and books and their will to quit smoking by self-administerd questionnaire. RESULTS: The significant factors associated with smoking cessation were higher education (OR=1.85, 95% CI 1.26-2.74), non-religion (OR=0.56, 95% CI 0.38-0.83), drinking (OR=0.40, 95% CI 0.27-0.61), awareness (OR=1.30, 95% CI OR=1.03-3.25) and seriousness (OR=1.29, 95% CI 1.19-1.39) for smoking related disease, benefit (OR=1.21, 95% CI 1.16-1.27), and barrier (OR=0.78, 95% CI 0.74-0.83), motivation (OR=1.21, 95% CI 1.12-1.30), and the will to quit smoking (OR=1.70, 95% CI 1.56-1.85). CONCLUSION: This study suggested that effective smoking cessation program should be based on awareness and seriousness due to smoking related diseases, health benefit and barrier to quitting smoking, company's support, the individual's will to quit and various motivation methods.

BACKGROUND: Lung carcinogenesis is a multistage process involving alterations in multiple genes and diverse pathway. Mutational activation of oncogenes and inactivation of tumor suppressor genes, and subsequent increased genetic instability are the major genetic events. The p53 gene and FHIT gene as tumor suppressor genes contribute to the pathogenesis of lung cancer, evidenced by mutation, microsatellite instability(MI) and loss of heterozygosity(LOH). METHODS: We analysed genetic mutations of p53 and FHIT gene in 29 surgical specimens of nonsmall cell lung cancer using PCR-single strand conformation polymorphism, DNA sequencing and RT-PCR. MI and LOH were analyzed in loci of D3S1285, D9S171, and TP53. RESULTS: In 2 cases, point mutation of p53 gene was observed on exon 5. MI of 3 times and LOH of 14 times were observed in at least one locus. In terms of the location on microsatellite, D3S1285 as a marker of FHIT was observed in 5 cases out of 26 specimens;D9S171 as a marker of p16 in 5 out of 17;and TP53 as a marker of p53 in 7 out of 27. In view of histologic type, squamous cell carcinoma presented higher frequency of microsatellite alteration, compared to others. Mutation of FHIT gene was observed in 11 cases and 6 cases of those were point mutation as a silent substitution on exon 8. FHIT mRNA expression exhibited deletion on exon 6 to 9 in 4 cases among 15 specimens, presenting beta-actin normally. CONCLUSION: Our results show comparable frequency of genetic alteration in nonsmall cell lung cancer to previous studies of Western countries. Microsatellite analysis might have a role as a tumor marker especially in squamous cell carcinoma. Understanding molecular abnormalities involved in the pathogenesis could potentially lead to prevention, earlier diagnosis and the development of novel investigational approaches to the treatment of lung cancer.

The lactose, total nitrogen and total lipid contents of human breast milk were determined longitudinally after protein and term deliveries. Milk samples were obtained from day 2 to 5, on weeks 1, 2, 4, and 6 after preform (PM: n=24) and term (TM: n=22) deliveries. The lactose contents of PM and TM increased from 5.28 g/dl and 5.93 g/dl at days 2 to 5, to 7.95 g/dl,7.87 g/dl at 6 weeks, respectively. The total nitrogen contents of PM and TM decreased significantly during the first 6 weeks after birth (from 374 to 220 mg/dl versus 382 to 220 mg/dl respectively). However the total lipid contents of the PM and TM increased during the same periods. Significant differences in the total lipid contents between the PM and TM were 2.15 versus 3.27 g/dl at 2 weeks, and 3.26 versus 2.52 g/dl at 6 weeks, respectively. The energy intakes of preform infants was 134.8 kcal/kg/d during the 6 weeks of lactation, which satisfied with energy requirements (85-130 kcal/kg/d) of the preform infants.

The authors conducted a clinical observation of 13 cases of pulmonary aspergilloma at Yeungnam University Hospital from March 1983 to March 1992, and the following results were observed: 1) The male to female ratio was 1 : 1.2, and the age distribution was ranged 30 to 67 years old. 2) All cases were symptomatic : hemoptysis, cough, sputum and dyspnea. Especially, hemoptysis was the presenting compliant in 10 patients (77%) 3) The underlying lung disease were pulmonary tuberculosis in 9, COPD in 5 and bronchiectasis in 2. 3 cases were without underlying disease. 4) According to radiographic appearance, 8 cases had the typical crescent sign and 5 cases were seen nodular lesion. And the lesions of 11 cases were located in both upper lung. 5) 10 cases were treated with surgical resection. Among these cases, 8 cases were alieved and 2 cases, died. And other 3 cases were treated with conservative treatment. We suggest that these findings would be helpful for the diagnosis and treatment of pulmonary aspergilloma and further study might be needed to evaluate the prognosis of pulmonary aspergilloma.

Five cases of intracranial lipoma diagnosed by MR are presented. MR imaging was performed on a 0.2T permanent unit using T1 weighted, proton density-weighted, and T2 weighted spin echo sequences. In two patients, gadolinium-enhanced T1 weighted image was also obtained. The lipomas were located dorsolaterally to the splenium of the corpus callosum (n=1), inferior to the splenium (n=2), in quadrigeminal plate(n=1) and in the presumed corpus callosum area in the case of agenesis of corpus call?um (n=1). The size and shape of the lipomas were variable. No contrast enhancement was seen in post contrast study. Sagittal T1 weighted image appeared to be the most useful imaging plane for the demonstration of the relationship between the lipoma ad the adjacent normal structures. The Homogenous signal intensity paralleling the fat signal and the characteristic location of the lesion are considered to be helpful in the differential diagnosis from dermoid cyst or teratoma.
