OBJECTIVES: The purpose of this study was to investigate the job stress level of post-graduate students in schools of natural sciences and engineering in order to evaluate the relationship between temperament, character and job stress. METHODS: All the 254 subjects were interviewed by means of a structured questionnaire, KOSS-SF and TCI-RS. Among them, only 220 were eligible for analysis. Statistical methods used included chi-square test, independent t-test, Mann Whitney test, ANOVA test, correlation analysis and multiple linear regression analysis with PASW ver.18. RESULTS: Age, degree course, working hours per week, work tenure, smoking habits, exercise, and disease history were associated with job stress and hours worked per week, smoking being associated with TCI-RS subscales. For job demand, interpersonal conflict scores were higher than Korean standard. In multiple linear regression analyses, R2 scores of temperament subscales on job stress were 0.099~0.312 and those of character subscales on job stress were 0.056~0.249. CONCLUSIONS: Job stress was associated with the unique traits of individuals, temperament and character. In order to manage job stress, the personality, as well as work environment, was found to be important considerations.

Purpose: To determine the differences in the radiographic findings of miliary tuberculosis between patients with and without associated acute respiratory failure (ARF). MATERIALS AND METHODS: We retrospectively reviewed 32 patients in whom miliary tuberculosis had been diagnosed, and assigned them to one of two groups: with ARF (n=10), and without ARF (n=22). Chest radiographic findings such as the presence of miliary nodules, cosolidation, ground-glass opacity (GGO), pleural effusion, small calcified nodules and linear opacities were assessed, the size and profusion of nodules in each of four zones were analyzed and scored using the standard radiographs of the International Labor Organization, and the extent of consolidation and GGO were scored according to the percentage of involved lung. We compared the radiologic findings between the two groups. RESULTS: Ground-glass opacity, consolidation, and pleural effusion were seen more frequently in miliary tuberculosis patients with ARF than in those without ARF. Although the size and profusion of nodules were similar in both groups (p>0.05), consolidation and ground-glass opacity in cases of miliary tuberculosis with ARF were significantly more extensive than in those without ARF (p<0.005). CONCLUSION: GGO and consolidation were more extensive in miliary tuberculosis patients with ARF. A finding of ground-glass opacity in miliary tuberculosis patients might be an early indication of developing ARF.

Doxylamine is common over-the-counter sleep preparations & frequently involved in overdoses. The clinical course is dominated by the anticholinergic effects, including central nervous system & autonomic effects. We report 4 cases of suicide attempts in adults where ingestion of the doxylamines were complicated by rhabdomyolysis. They ingested doxylamines variable amount & were carried to emergency department. They complained gastrointestinal or central nervous system symptoms. Gastric lavages & administrations of activated charcoal were done. Creatine phosphok inase levels were normal or markedly elevated on arrival, but peaked several days later. Serum creatinine levels were normal. 99mTc-MDP bone scans were showed increased muscle labelling at the regions of muscle injury. They were treated with hydration, urine alkalinization, & supportive measures in hospital. On considering cause of rhabdomyolysis, our patients did not show any evidence of viral illness or coingestion of other potential myopathic toxins to support a secondary cause of rhabdomyolysis. The mechanism of rhabdomyolysis in cases of doxylamine overdose seems to be a direct toxic effect of the drug on striated muscle, but the exact mechanism is not clear. In all cases where such overdoses are suspected, consideration should be given to obtaining a urinalysis & a creatine phosphokinase level on arrival & creatine phosphokinase levels are carefully followed. Primary detoxication included gastric lavage & administration of activated charcoal. The patient's urine output & renal function should be closely monitored.
