To investigate the factors influencing workers' perception and attitude toward special periodic health screening test for workers, a survey with self-administered questionnaires was performed on 279 workers who had special periodic health screening test from september 1 to October 15, 1994. A study model was developed by modifying the health belief model. The end and intermediate response variables of the model were the voluntary participation and necessity perception on the special screening for workers, and The result of analysis was consistent with the study model. Rates for the necessity perception and voluntary participation on the special1 screening for workers were 77.2%, 79.2%, respectively. Factors influencing on the voluntary participation were necessity perception, benefit of special screening for workers, and cue to action. And on the necessity perception were susceptibility and severity to occupational disease, knowledge to special screening for workers, and support of company. General and occupational characteristics influencing on the susceptibility and severity to occupational disease were sex, age, educational level, work duration, and health education. On the knowledge to special screening for workers were age, educational level, work duration, and locus-of-control. On the benefit of special screening for workers were age, locus-of-control, pride on health, and health education. Therefore, to increase the voluntary participation and necessity perception on the special periodic health screening for workers, l) if a worker is judged as occupational disease, the judgment should be widely known in his workplace, 2) the screening result forms should be directly sent to the workers themselves, 3) for the positivity of employers, the campaign and education program subjected to them should be planned, 4) health education should give the first consideration to the younger, lower educational level, and newly employed women, and its frequency should be increased and it should be more frequently dealt with occupation-related subjects, and 5) the employers should have a careful concern in not being disadvantageous to workers due to result of screening.

OBJECTIVES: Over the last 30 years, despite the increasing sophistication in medical care, the mortality of acute renal failure(ARF) has remained virtually unchanged at 40-50%, but the reasons remain unknown. This study intend to identify prognostic risk factors influencing survival and predict the mortality in ARF patients. METHODS: We retrospectively analyzed 152 patients with ARF who required renal replacement therapy, or whose serum creatinine level above 5 mg/dl, from Jan. 1988 to May. 1995. Multiple factors which may influence mortality were evaluated by univariate and multivariate analysis. RESULTS: 1) Of the 152 patients, 97 were male and 55 were female. The mean age was 47 years and the overall mortality was 36.8%. 2) Based on the univariate analysis, age>60 years, cause of ARF, APACHE II score, number of failing organs, peak serum creatinine level, PaO2, coma, hypotension, ARDS, GI bleeding, ventilatory support, need for antiarrhythmics, DIC, cardiovascular failure, pulmonary failure, neurological failure, and gastrointestinal failure were all significant factors discriminating between survivors and nonsurvivors(p<0.05) 3) By multivariate analysis, hypotension, coma, ventilatory support, and age over 60 years were significant independent predictors influencing survival in ARF patients and logistic equation and logit score were as follows : z=-2.04+1.32(age over 60)+2.18(hypotension)+2.88 (ventilatory support) + 3.28(coma) P=ez/(1+ ez) 4) In ROC(receiver-operating characteristic)curve, when the cutoff point was 0.2, maximum sensitivity was 75% and maximum specificity was 82%. CONCLUSION: In ARF, prognostic risk factors for mortality were age over 60 years, hypotension, assisted ventilation and coma. The logit score by multiple analysis is a reliable predictor of mortality in ARF patients, however the further studies are required to confirm these results.

Background : It has been suggested that thrombospondin (TSP) is a p53-dependent negative regulator of tumor angiogenesis. TSP expression and localization in hepatocellular carcinomas (HCCs) and its association with overexpression of p53 protein were investigated. Methods : TSP-1 and -2 expressions were examined in 40 HCC specimens by immunohistochemical staining and in 4 HCC cell lines by Western blotting. In addition, p53 protein expression and microvessel density (MVD) were correlated with the TSP expression. Results : Strong immu- nopositivity for TSP-1 was observed in fibroblasts, vascular endothelial cells, and some vas- cular smooth muscle cells of the stroma in 18 cases (45%), and in tumor cells in 3 cases (7.5%) of 40 cases of HCC. Immunoreactivity for TSP-2 was observed in only the sinusoidal lining cells of the tumor in 15 cases (46%), and in tumor cells in 2 cases (6%) of 32 cases of HCC. TSP-1 expression was inversely correlated with MVD (p=0.028), but TSP-2 expression did not show any correlation with MVD. Although p53 was overexpressed in 17 cases, there was no significant correlation between TSP and p53 expressions. None of the HCC cell lines expressed TSP-1 or -2. Conclusions : These findings indicate that TSP-1 is mainly derived from nonparenchymal cells, and may decrease tumor angiogenesis in HCC.

This study was conducted to analyse medical facilities utilization based on predisposing factors, enabling factors and need factors, and effect of these factors on medieal facilities utilization, by applying Anderson's medical care service behavioral model as the most well known medical demand model to 163 available for interview among 246 workers who, as the result of health examination in 1994, were evaluated as the non occupational diseases. The results of this study were summarized as follows. Among variables of predisposing factors, knowledge for disease showed significant relations with the medical utilization, other variables of predisposing factors, such as sex, age, marital status, educational level, number of family members, type of occupation, attitude toward the disease, were not related with the medical utilization. The medical utilization was not related with variables of enabling factors. Among variables of need factors, medical advice of health personnel was significant variable for medical utilization. With multiple logistic regression analysis, the significant variables haying an effect on the medical facllities utilization were the type of occupation and knowledge for the disease among predisposing factors, ana seriousness for the disease and medical advice of health personnel among need factors. In case of the production job, the medical facilitles utilization was higher for the persons with more knowledge for disease and experience of medical treatment guidance. The number of non-occupational diseases detected, but untreated person was 76 (46.6%) of total subjects, mainly because the non-occupational diseases seemed to be a slight disease (55.3%). On consideration of above findings, health education for workers and adequate medical advice by health personnel would be needed for health management of workers with non occupational diseases.

To identify the drug abuse status and its determinant factors in high school boys in Taegu, the study was performed from April to May, 1995. Study population were selected by cluster sampling method and total 5,665 students replied to the self-administered questionnaire survey(2,207 in academic high school, 3,458 in business high school). The major findings were as follows; The proportion of drinking, smoking experience was 55.0%, 45.8%, respectively, and the proportion of current drinker, current smoker was 27.2%, 27.5%. The drinking, smoking experience rate of second grade students was higher than first grade and it was higher in business high school boys. The proportion of a stimulant, a hallucinogen, hemp leaf cigarets experience was 3.2%, 1.6%, 0.1%, respectively. Drug abuse had significant association with home environment(lower economic status, frequent move, death of father or mother, apart from family), parents environment(parents' indifference, parents' drinking and smoking, etc.), school life(lower school grades, intimate friend's drug abuse, etc.), generous attitude to drug abuse, higher level of stress. Students who replied that the law prohibited immature person(students) from drinking and smoking showed lower drug abuse rate. In multiple logistic regression analysis, second grade students, business high school students, parents' indifference, lower school grades, intimate friend's drug abuse, no recognition of the fact that the law prohibits high school students from drinking and smoking, generous attitude to drug abuse, higher level of stress were significantly related with alcohol abuse and smoking. Other drugs abuse were related with above factors. On consideration of above findings, to prevent students from drug abuse, we have to try together in house, school, and society.

A simple, rapid and selective liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) is developed and validated for quantification of venlafaxine in human plasma with simple liquid-liquid extraction step consisted of extraction with ether and dichloromethane for 10 min and mixing with 1 M sodium acetate in human plasma using fluoxetine as an internal standard (IS). The analyte are separated using an isocratic mobile phase consisted of acetonitrile and 5 mM ammonium formate (4/3, v/v) on a isocratic YMC hydrosphere C18 (2.0x50.0 mm, 3.0 microm) column and analyzed by MS/MS in the multiple reaction monitoring (MRM) mode using the transitions of respective [M+H](+) ions, m/z 278.2-->260.3 and m/z 310.1-->148.1 for quantification of venlafaxine and IS, respectively. The standard calibration curves showed good linearity within the range of 1.0-200.0 ng/mL (r2=0.9986, 1/chi2 weighting). The lower limit of quantification (LLOQ) was 1.0 ng/mL. The retention times of venlafaxine and IS were 0.6 min and 0.7 min that means the potential for the high-throughput potential of the proposed method. In addition, no significant metabolic compounds were found to interfere with the analysis. Acceptable precision and accuracy were obtained for the concentrations over the standard curve range. The validated method was successfully applied to bioequivalence study after 75-mg of venlafaxine sustained-release (SR) capsule in 24 healthy Korean subjects.

BACKGROUND AND OBJECTIVES: In addition to diagnostic criteria, a broad range of nonspecific clinical features can be found in patients with Kawasaki disease. This lack of specificity may cause confusion with other febrile illnesses and delay the diagnosis of Kawasaki disease. The purpose of this study is to describe common associated symptoms and their clinical significances in children affected with Kawasaki disease. SUBJECTS AND METHODS: As a retrospective study, we reviewed the medical records of 121 children who were treated for Kawasaki disease at Presbyterian medical center from January 2005 to June 2010. All clinical symptoms, laboratory data and echocardiographic findings in patients with KD were collected and analyzed. RESULTS: We found that there are 9 associated symptoms, namely cough, rhinorrhea, sputum, abdominal pain, vomiting, diarrhea, arthralgia, headache and seizure, which occur in patients with Kawasaki disease. Among the study group, there were only 32 children with no associated symptoms (26.4%). Patients with abdominal pain and headache had an older mean age than those without such symptoms. The incidence of seizure was significantly higher in incomplete Kawasaki disease patients compared with those with complete Kawasaki disease. Vomiting was highly associated with IVIG non-responder group. CONCLUSION: To decrease the incidence of serious coronary complications due to delayed diagnosis, physicians need to be aware of the manifestations of Kawasaki disease and the possibility of associated symptoms, which, being unspecific, may otherwise not raise any red flags.
