PURPOSE: This study aims to test the validity and criteria-related reliability of the Korean version of the Copenhagen Psyco-social Questionnaire version II (COPSOQ-K) assessing the psychosocial working environment. METHODS: The COPSOQ-K was developed through forward-backward translation techniques, and revision based on feedback from focus groups. Survey data were collected from 311 office workers who worked in one workplace. An internal consistency reliability was estimated by Cronbach's alpha. The impacts of the COPSOQ-K scales on job satisfaction, self-rated health, stress, sleeping troubles, burnout, and sickness absence were analyzed with multiple regression model or multiple logistic regression model, adjusted age and gender using SAS version 9.3. The Pearson correlation coefficients between the COPSOQ-K scales and Korean job stress and its subdomain were identified. RESULTS: Cronbach's alpha of COPSOQ-K scales was adequate or good (0.66~0.87). The major COPSOQ-K scales predict job satisfaction, self-rated health, stress, sleeping troubles burnout, and sickness absence. The major COPSOQ-K scales were correlated with Korean job stress and its subdomain. CONCLUSION: The COPSOQ-K scales have satisfactory reliability and criteria-related validity. The COPSOQ-K scales will be useful for the future studies and practices associated with psychosocial working environment.

Wallerian degeneration is well known as the anterograde degeneration of axon and their accompanying myelin sheath from injury to the proximal portion of the axon or its cell body. The most common cause of wallerian degeneration is cerebral infarction. Authors experienced three patients with old hemispheric infarct with typical wallerian degeneration in the brain stem, which was demonstrated by magnetic resonance imaging (MRI) in two cases and CT in one case. This report demonstrates the wallerian degeneration in the corticospinal tract on the MRI and CT with the brief review of the literatures.

BACKGROUND: Chlamydia pneumoniae, a new species of the obligate intracellular Chlamydia, has been recognized as a significant pathogen that causes infection of the human respiratory tract and has recently been associated with coronary atherosclerosis. Diagnosis of infections with C. pneumoniae is problematic, because the syndrome usually presents few distinguishing features and culture of the organism is far more difficult than other Chlamydia species. To further improve the cell culture isolation and passage of C. pneumoniae organisms. we have studied several chemical and physical factors that might affect their viability and growth. METHODS: C. pneumoniae strain (TW-183) was obtained from the Centers for Disease Control, Atlanta. Ga. First we compared McCoy HeLa-229, and HEp-2 cells in the search for a more efficient and practical cell culture system. The growth rate of C. pneumoniae was assessed by the effects of diethylaminoethyl-dextrin, by the adequate centrifugation force and time, by the growth promoting effect of cycloheximide, and by the optimal incubation time. All of the results were evaluated by the indirect immunofluorescent stain using the genus-specific monoclonal antibody(HYMo 1-1) to Chlamydia. RESULTS: The HEp-2 cell was the most efficient for culturing C. pneumoniae and the inclusion bodies in monolayer were increased with DEAE-dextran pretreatment at 30microgram/ml. Also application of a centrifugal force of 1.500 xg for at least 15 minute during inoculation enhanced the growth of C. pneumoniae. The best concentration of cycloheximide in the culture medium for host cell cytostasis was 1microgram/ml. The yields of organisms were greater when the cultures were harvested at 48 hours. CONCLUSIONS: We suggest that this system may make it more practical for laboratories to culture for C. pneumoniae.

PURPOSE: This study tried to explore factors influencing on job maintenance of the mentally disabled who employed before. The subjects of this study were the mentally disabled who participated in community mental health center and social rehabilitation center, there had experienced a job in the past. METHODS: The number of community centers were 27 places, there were located in different region. The number of participants were 221 persons agreed to this study. Data was analyzed by Mean, SD and logistic regression analyzation using SPSS/WIN 14.0. RESULTS: General character such as age was significant factor. Monthly pay and working a day in the midst of job related factors were significant. Moreover, job rehabilitation program satisfaction rate and social support revealed significant factors. CONCLUSION: On the basis of results, Job rehabilitation programs for job maintenance of the mentally disabled should be development and establish mediate strategies to improve social support to them.

The CT findings of the acute cerebral infarction are well known. However the CT findings of early stroke within 24 hours of the onset have not been sufficiently reported. The purpose of this study is to evaluate early acute cerebral infarction on CT within 24 hours after ictus. The early and accurate CT diagnosis could lead to the appropriate therapy and improved outcome of the patients. Authors retrospectively analyzed 16 patients with early acute cerebral infarction. Acute cerebral infarction was confirmed by follow-up CT in 11 patients, SPECT in 4 patients, and MRI in 1 patient. The CT findings of early acute cerebral infarction include effacement of cortical sulci or cistern (n=16, 100%), hyperattenuation of MCA (n=3), obscuration of lentiform nucleus (n=6), loss of insular ribbon (n=6) and subtle low density in hemisphere (n=5). The most frequent findings was effacement of cortical sulci in our study, and it was though to be the most important sign of early acute cerebral infarction.

PURPOSE: This study aims to assess the effects of psychosocial work environment and self-efficacy on stress, depression, and burn-out among office workers. METHODS: Survey data were collected from 331 office workers who worked in one workplace from April 10 to 30, 2012. The impact of psychosocial work environment and self-efficacy on stress, depression, and burn-out was analyzed with hierarchical multiple regression using SAS version 9.3. RESULTS: Work-family conflicts and emotional demands were identified as main factors influencing mental health. Other work environment factors influencing mental health were role clarity for stress, possibilities for development, meaning-of work, social support-from supervisors and job insecurity for depression, and social community at work for burn-out. Self-efficacy was correlated with most psychosocial work environment and factor with independent influence on stress and depression. The final models including general characteristics, psychosocial work environment, and self-efficacy accounted for 34%, 44%, and 36% for stress, depression, and burn-out respectively. CONCLUSION: To promote mental health in office workers, there is a need to decrease work-family conflicts and emotional demands and to improve work organization and job contents, social support, and self-efficacy.

Common peroneal nerve injury has been reported as the most frequent lower extremity peripheral nerve injury. The peroneal nerve may be particulary prone to direct or indirect injury by penetrating trauma or external compression by it's superficial route to bony prominence of fibular neck. By the development of microsurgical technique, recently epineural repair, fascicular group repair, and interfascicular graft were tried. The authors have experienced five cases microsurgical repair of common peroneal nerve injury around the knee joint from December 1990 to November 1991, and motor and sensory result was relatively good.

BACKGROUND: Urinary tract infections (UTIs) are the most frequent nosocomial infections and are frequently associated with indwelling urinary catheters. It is known that adherence to standard infection control measures for urinary catheters can reduce UTIs in hospitals. This study was performed to evaluate the effect of education in reducing catheter-related UTIs (CR-UTIs) in intensive care units (ICUs) of a university hospital. METHODS: CR-UTIs were prospectively monitored for all patients with indwelling urinary catheters in ICUs from July 2006 through December 2007. Recommendations based on previously known guidelines for catheter insertion, catheter management, and specimen collection to prevent CR-UTIs were formulated and educated in March 2007. Knowledge and adherence level were evaluated before and after educating healthcare workers about the recommendations using questionnaire. Changes in knowledge and adherence level before and after education were compared by Chi-square test. Changes in the rate of CR-UTIs and urinary catheter utilization ratios were also analyzed by Fisher's exact test. RESULTS: After education, knowledge level of and adherence level to most of the recommendations were improved significantly. The rate of CR-UTIs significantly decreased by 48% from 7.43/1,000 catheter-days before intervention to 3.87/1,000 catheter-days after intervention (P=0.02). CONCLUSION: Surveillance for nosocomial infections and education for standard infection control measures are very important in preventing CR-UTIs in ICUs.
