This study statistically analyzed the laboratory accidents by investigating 806 laboratory accident survey reports which were officially submitted to government from 2013 to June 2017. After comparing domestic and foreign accident classification criteria, the laboratory accidents were classified using KCD7(Korean Standard Classification of Diseases) and OIICS(Occupational Injury and Illness Classification System) criteria. For the type and part of injury, KCD7 classification criteria was adopted. And, for the cause and occurrence type of accidents, OIICS was adopted to analyze the laboratory accidents. Most of injuries happened to the wrist and hand caused by sharp materials or chemical materials. The analysis of accident cause showed that accidents resulted in medical practice and accidents from handtools and chemical materials such as acid and alkali frequently occurred. The major occurrence types of laboratory accidents was body exposure to the chemical materials such as hydrochloric acid and sulfuric acid. In addition, the accidents resulted in destroy of grasped object or falling object were frequently reported.

The present status of the traffic accident rate in Korea shows that it is the highest in the world with a continuously increasing trend. Human factors account for 90% of the causes of traffic accidents. Therefore, the purpose of this study was to determine some human factors related to traffic accidents by studying the relationship between health status and traffic accidents. To accomplish this purpose, all taxi companies located in the Seoul area were divided in three groups according to the number of taxi possessed, then some companies in each ?roup were randomly selected for study, and a total of 222 drivers in those selected companies were questioned and examined from April 15 to April 22, 1989. Seventy drivers among 222 had experienced a traffic accident. A $x^2$-test was performed on the data, then, factor analysis and discrminant analysis were executed with the following results: 1. The drivers complaining of gastroenteric symptoms numbered 110(49.5%), which was the major symptom among all drivers complaining of poor health. 2. In the primary analysis, variables related to traffic accidents were divided into general, occupational, and health characteristics. Drivers having no traffic accident experience and drivers having that experience were subjected to question about age, educational level, residential status, monthly average income, working hours and days, degree of satisfaction with their profession and homelife, degree of worry about health. degree of fatigue, medication, drunken driving, and illness, but there were no statistical significances. 3. In the factor analysis, the 8 health variables which cause traffic accidents were classified into 3 common factors which were perceived health factor, sleeping and drunken driving, and visual acuity and smoking factor. Perceived health was the factor which contributed most to explaining accidents. 4. In the discriminant analysis, a correct prediction rate of 68.0% was obtained in the factors of all the characteristics. 5. Degree of sttisfaction with their homelife and educational and economic factor in the general characteristics, degree of satisfaction with their profession in the occupational characteristics, and sleeping and drunken driving in the health characteristics were selected as statistically significant factors to discriminant the traffic accident. 6. Among the factors of the general, occupational, and health characteristics, degree of satisfaction with their homelife, driving experience, family factor, perceived factor were selected as the statistically significant factors.

This study was carried out to find out the basic data required to plan and develop Rehabilitation Day Care Program for the stroke survivor's family in Korea. The subjects comprised of 92 stroke survivor's family who discharged from 4 hospitals in Seoul during the past 2 years. The data were collected from August 3, 1998 to September 18, 1998, through interviews with questionnaires about general characteristics, activities of daily living, depression and service need of rehabilitation day care program at the outpatient clinics by trained nursing graduates. Data were analyzed with descriptive analysis, Pearson's correlation analysis, and Stepwise multiple linear regression analysis using SPSS/WIN 10.0 program. The results obtained are as follows; 1. The mean score of the general need of rehabilitation day care program of stroke survivor's family was 3.10(range 1-4). The highest need among the service categories of the rehabilitation day card program was self-care and restorative activities category(3.30), and health services referral category, recreation category, psychosocial activities category in order. The needs of each category are as follows. In the health services referral category, the need for dental examination and medical examination were highest, followed by the need for physical therapy and occupational therapy. In the psychosocial activities category, the need for family counselling was highest. In the self-care and restorative activities category, the need for ROM exercise training was highest, followed by bowel training, and ambulation training. 2. The need of family for rehabilitation day care program service displayed a correlation with the level of education, ADL, and the level of depression, and a reverse correlation with age, illness intrusiveness, depression, knowledge, subject and object burden and relationship with stroke survivors. 3. The stepwise multiple linear regression analysis revealed following results. For the need for rehabilitation day care program service, 22.6% of the variance was initially explained by level of family's knowledge about caring method for stroke survivors, 8.8% was the level of subjective burden and 5.4% was relationship with stroke survivors. In conclusion, above characteristics should be considered to develop stroke survivors' rehabilitation day care program.

Purpose: The purpose of the study was to identify attitudes of middle managers toward employees with psychological problems and to determine factors affecting their attitudes. Methods: A questionnaire with Community Attitudes Toward Mentally Ill (CAMI) scales was administered to 161 middle managers working in small and medium-sized enterprises based in Seoul and Gyeonggi Province. Results: There are four separate subscales on the CAMI. Mean score for authoritarianism was $35.0{\pm}4.4$, benevolence $23.0{\pm}4.8$, social restrictiveness $32.3{\pm}4.9$ and community mental health ideology $27.2{\pm}5.1$ According to multiple regression analysis, middle managers with no experience of learning mental illness through mass media or higher levels of depression symptom were more authoritative and less benevolent towards employees with psychological problems. The experience of meeting a patient with mental problem contribute to positive attitudes toward people with mental illnesses in social restrictiveness subscale and community mental health ideology subscale among CAMI. Conclusion: This study suggests that experience of having patients with mental problems and information on psychological problems will have great influence on attitudes of middle managers toward employees with psychological problems. It might be important to help middle manager manage their depression because their depression also affects their attitudes toward employees with psychological problems.

Purpose: The purpose of this study is to determine the effect of motor imagery training on residual upper extremity strength and activities of daily living of chronic cervical spinal cord injury patients. Methods: Twelve ASIA A B patients, who had more than a 12-month duration of illness and C5 or 6 motor nerve injury level, were randomly divided into experimental group (n=6) and control group (n=6). Patients in the experimental group performed motor imagery training for five minutes prior to general muscle strengthening training, while those in the control group performed general muscle strengthening training only. The training was performed five times per week, 30 minutes per day, for a period of four weeks. General muscle strengthening training consisted of a progressive resistive exercise for residual upper extremity. Motor imagery training consisted of imagining this task performance. Before and after the training, EMG activity using BTS Pocket Electromyography and Spinal Cord Independent Measure III(SCIM III) were compared and analyzed. Results: The residual upper extremity muscle strengths showed improvement in both groups after training. Comparison of muscle strength improvement between the two groups showed a statistically significant improvement in the experimental group compared to the control group (p<0.05). SCIM III measurements showed significant improvement in the scores for Self-care and Transfer items in the experimental group. Conclusion: Motor imagery training was more effective than general muscle strengthening training in improving the residual upper extremity muscle strength and activities of daily living of patients with chronic cervical spinal cord injury.

Purpose : This study was performed to understand the relationship between hand and mouth shapes using functional magnetic resonance imaging(fMRI). Methods : Two healthy volunteers without any previous history of physical or neurological illness were recruited. fMRI was done that volunteers was 6 repeated of natural mouth, close mouth and open mouth while power grip and pinch grip movement. Results : Cerebral cortex activation was not well observed for the natural mouth during the power grip exercise. For the closed mouth, the temporal lobe, Broca's area, the prefrontal area related to thinking and judgment, the supplementary motor area, the auditory area and Wernicke's area were activated. For the open mouth, cortical activation was also observed in the temporal lobe, Wernicke's area, the prefrontal area related to thinking and the orbital frontal area related to visual sense. During the pinch grip exercise, cortical activation was observed for the natural mouth in the primary sensory area, Wernicke's area, the primary and supplementary motor area, and the prefrontal area. For the closed mouth, cortical activation was observed in the temporal lobe, Wernicke's area, the prefrontal area related to thinking, the secondary visual area, the primary sensory area and the supplementary motor area. In the case of the open mouth, cortical activation was observed in a few parts in the temporal lobe as well as Wernicke's area, the prefrontal area related to thinking, and other areas related to visual sense such as the primary visual area, the secondary visual area and the visual association area. Conclusion : Brain was more activation for close mouth and open mouth more than natural mouth movement.

Objectives Atypical antipsychotics show better treatment efficacy, safety and tolerability than typical antipsychotics. Among the adverse events observed during treatment with antipsychotics, extrapyramidal syndrome (EPS) and negative symptoms has been greatly reduced. But still, weight gain is receiving growing attention. The aim of this study was to investigate the association between therapeutic response to atypical antipsychotics and weight gain in admission status. Methods The study was conducted for Korean inpatients with schizophrenia in a university hospital in Seoul, between Jan 2006 and Dec 2010. Data was collected by reviewing the medical record of 39 consecutively hospitalized patients with Schizophrenia (DSM-IV) at a university hospital. Positive and Negative Symptom Scale (PANSS), Body Mass Index (BMI) and body weights were measured. Results No significant difference was observed for sex, age, illness onset age, family history of schizophrenia, numbers of hospitalization before treatment, educational years, marriage status, occupational status and subtype of schizophrenia between weight gainers and non-weight gainers. Regarding treatment response to atypical antipsychotics, weight gainers show significantly more PANSS decrease than non-weight gainers during admission period. Conclusions Our findings suggest that it appears to be more likely to respond to atypical antipsychotics in weight gainers than non-weight gainers (that weght gainers appear to be more likely to respond to atypical antipsychotics than non-weight gainers). These results show that the antipsychotic-induced body weight gain is associated with therapeutic response of antipsychotics in Korean inpatients with schizophrenia.
