Objectives: This study is planned to assess the trend of occupational injuries in Korea from 2001 to 2010. Methods: Ten years of occupational injuries, from 2001 to 2010, were analyzed in order to investigate the changing profiles according to the various characteristics of injuries; economic sectors, age of the injured, and type of injuries. The changing profile of occupational injuries was investigated by comparison with an index-created relative value based on the number of cases of reference category. Results: The fatalities of construction, forest, agriculture, and service show the increasing trend. The nonfatal occupational injuries of the manufacturing sector were higher than those of other sectors in every year but the fatal occupational injuries of construction workers were higher than those of the manufacturing sector. Occupational injuries occurring due to amputation and those of slip and trip increased. The number of occupational injuries for the worker groups of 24 years old and below decreased and 45 years old and above increased. In comparison to the figure of fall from height, the figures of slip and trip or caught in equipment are higher in every calendar year. Conclusion: This study find out construction, forest, agriculture, and service sectors, aged worker with 45 years old and over can be target population for the strategies of occupational safety.

The purpose of this study was to investigate(1) the effects of clothing cues of 20s young man in business suits on the perception of occupational suitability in an office setting and (2) the effect of Perceiver's self-monitoring and sex on the perception of occupational suitability formed by the function of clothing cues. The experimental design of this study was between-subjects 23 factorial design. The experimental materials developed for the study were a set of stimuli and a response scale. The stimuli consisted of 8 color photographs of a young man wearing business suits which were manipulated at two levels for each of three clothing cues (suit color, suit style, necktie color). Each one of eight sub-samples included 14 subjects from 2 perceiver groups by sex. The questionaires used to measure perceivers' responses to the stimuli were constructed in 12 five-point likert scale representing occupational suitability and self-Monitoring was measured by the self-Monitoring Scale by Gangestad adn Snyder. The subjects consisted of 224 male and female college students in Seoul. The data was processed by ANOVA and MCA(Multiple Classification Analysis). The result were as follows: (1) The Clothing cues of young man in business suits(suit color, suit style) partially influenced the occupational suitability. (2) The perception of occupational suitability formed by the clothing cues of a young man in business suits was partially influenced by the perceiver's self-monitoring and sex. Female high self-monitoring group were more affected by the clothing cues than any other groups.

Purpose: We were to identify the differences of "Job stress" and "Depression scores" in the divided groups by self-efficacy. And the factors affecting Depression scores were analyzed. Method: This study was conducted from July 2006 to September 2006. Collected 295 surveys were used in this study among 311 surveys since 16 surveys offered insufficient data. SPSS for Windows 10.0 was used to analyse the data. Result: We identified the factors of "Occupational climate", "Job control", "Job demand" as affecting the depression scores in the lower self-efficacy group by the multi-variables statistical analysis. And this statistical model had 12.5% explainable power. Also, the factors of "Occupational climate" were identified as affecting the depression scores in the higher self-efficacy group. And the statistical model had 9.0% explainable power. Conclusion: In the lower self-efficacy group, the scores of the job stress and depression were significantly higher. Therefore, in the lower self-efficacy group, the self-efficacy promotion programs should be needed for prevention of the related occupational diseases. The factors related job stress were identified as affecting the depression scores in both lower and higher self-efficacy groups. Therefore, job stress management program should be prepared for stress loading workers.

Cyclohexanone ($C_6H_{10}O$, CAS No. 108-94-1) is a colorless oily liquid obtained through the oxidation of cyclohexane or dehydrogenation of phenol. It is used in the manufacture of adhesives, sealant chemicals, agricultural chemicals, paint and coating additives, solvent, electrical and electronic products, paints and coatings, photographic supplies, film, photochemicals, and as an intermediate in nylon production. Owing to the lack of information on repeated inhalation toxicity of cyclohexaone, in this study, we aimed to characterize the subacute inhalation toxicity. B6C3F1 mice were exposed to 0, 50, 150, and 250 ppm of cyclohexanone for 6 hr/day, 5 days/week for 4 weeks via whole-body inhalation in accordance with the OECD Test Guideline 412 (subacute inhalation toxicity: 28-day study). Mortality, clinical signs, body weights, food consumption, hematology, serum biochemistry, organ weights, as well as gross and histopathological findings were evaluated between the control and exposure groups. No mortality or remarkable clinical signs were observed during the study. No adverse effects on body weight, food consumption, hematology, serum biochemistry, and organ weights, gross or histopathological lesions were observed in any male or female mice in any of the exposure groups, although some statistically significant changes were observed in organ weights. We concluded that no observable adverse effect level (NOAEL) is above 250 ppm in mice exposed to cyclohexanone for 6 hr/day for 5 days/week.

Background: Safety climate and occupational stress are related with occupational accident. The present study tried to identify the differences in safety climate and occupational stress according to occupational accidents experience and employment type (e.g., direct workers and subcontract workers). Methods: In this study, we conducted a survey using safety climate scale and Korean Occupational Stress Scale and classified the participants into four groups: direct workers working for accident-free departments, direct workers working for accident departments, subcontract workers working for accident-free departments, and subcontract workers working for accident departments for 2 years within the same workplace in the shipbuilding industry. Results: The direct workers and subcontract workers showed diverse results in subscales of safety climate and occupational stress. This result is supported by existing studies; however, further study is necessary for more supporting evidence and elaborative methodological approach. Conclusion: The necessity of management for safety climate and psychosocial factor such as occupational stress for both direct workers and subcontract workers as a whole is suggested by this study.

Purpose: This study was conducted to provide occupational performance evaluated by stroke patients themselves as an intervention according to the periods of its outbreak and examine the effects of it on their activities of daily living and life quality by using the Canadian Occupational Performance Measure (COPM). Method: The subjects of this research were divided into nine persons for the experimental group receiving the client-centered occupational therapy intervention and another nine for the control group getting the conventional occupational therapy intervention. And the intervention was performed for 30 minutes, three times a week, for total eight weeks. The level of activities of daily living was evaluated by the Functional Independence Measure (FIM), and life quality was tested by using SS-QOL. Results: First, about the difference of change in the FIM points of the two groups, there was statistically significant difference in Mauchly's sphericity verification (p<.05). Second, about the difference of change in the SS-QOL points of the two groups, there was statistically significant difference in Mauchly's sphericity verification (p<.05). Third, regarding the coefficient of difference in the change of FIM and SS-QOL points according to the two groups, there existed statistically significant correlation in all the evaluations of before, in the middle of, and after the FIM points and also before, in the middle of, and after the SS-QOL points (p<.05). Conclusion: With the findings of this research, we can see that the client-centered occupational therapy training group shows more improved activities of daily living and life quality than the conventional occupational therapy training group. Therefore, it is expected that the client-centered occupational therapy training will be applied usefully to clinical situations as an intervention to improve stroke patients' activities of daily living as well as life quality.

Purpose : Transcranial direct current stimulation is noninvasive method of cerebral cortical stimulation applied as an intervention to facilitate recovery in stroke patients. The purpose of this study was to examine the effects of transcranial direct current stimulation on depression and anxiety in stroke patients with the aim to finding a reliable method to reduce depression and anxiety in stroke patients. Methods : This study was conducted at A hospital located in D city from December 2022 to February 2023. Patients diagnosed with stroke were selected according to predefined study criteria and divided into two groups. 9 patients in experimental group underwent transcranial direct current stimulation and traditional occupational therapy, while 9 patients in the control group underwent sham transcranial direct current stimulation and traditional occupational therapy for 20 min per session 3 times per week for a total of 8 weeks. Beck depression inventory (BDI) and Beck anxiety inventory (BAI) were used to evaluate depression and anxiety in the patients before and after intervention. Wilcoxon signed rank test was used to compare differences before to after intervention. Mann-Whitney U test was used to compare the two groups. Differences with p<.05 were considered statistically significant. Results : First, both the experimental and control groups presented significant statistical difference before and after intervention on depression (p<.01). Comparison of two groups after intervention showed significant statistical difference in depression (p<.05). Second, the groups presented significant statistical difference before and after intervention on anxiety (p<.01). After intervention, the two groups showed significant statistical difference in anxiety (p<.05). Conclusion : Results of the present study demonstrated the effects of transcranial direct current stimulation on depression and anxiety in stroke patients, suggesting it may be a useful method of rehabilitation in this patient population; as such, further studies are warranted.

This study was carried out to investigate awareness and attitude of monitors in 206 small sized industries in Seoul and Kyeonggi area toward the occupational health programs using a specially prepared questionnaire. The industries had been running Government-Funded Subsidiary Program since 1998. The questionnaire was designed to be self-administered by respondents. Data were collected for two months from November to December, 1998. Major results are as follows: 1. Between two groups of industries, there were no significant differences in classification, scale, methods of production, existence of trade union, but in type of working pattern and facility ownership there were significant differences. 2. Between two groups of monitors, there were no significant differences in gender, age, marital status, rank, years of education, but in duration of working there was a significant difference. 3. In awareness and attitude of monitors toward their activities and occupational health programs, there was no significant difference by groups of industries, but a significant difference by type and scale of industry, gender, age, years of education 4. It was found that newly subsidized industries were more necessary to provide education programs on occupational health than old industries, and there was a significant difference between two groups of industries in the contents of education needed. In conclusion, it is desirable that the government should develop specific training programs for monitors on occupational health to provide them practical knowledge and specific skills which monitors can apply to their specific situation, and implement the training programs and continue Government-Funded Subsidiary Program for years until small scale industries would have been able to develop and keep their own health management system spontaneously.
