Hypertension is one of the most well known risk factors for cerebrovascular or coronary heart disease and is a major public health problem. Early detection and treatment of hypertension are essential, but the compliance of treatment on hypertension is not easy to achive. Hypertensive workers are being detected by the annual screening under the Labour Standard Law in Korea but the solidified control system for them is not existing. This study about workers 'Motive-Belief-Action in non-drug and drug treatment of their hypertension would be worthwhile to interpret how the workers actually behave in coping with hypertension, and also would be advisable to construct the follow-up program in Korea. In the field research process two criteria were used to select sample group. The first criterion included the workers who were screened to be hypertensive with their blood pressure above 160/95 in this survey. The second one was used to classify study-group respondents who had known their hypertension by successive annual screening. From such criteria a total of 156 male workers were sampled in 21 industries, the author interviewed them using the structured questionnaire which consisted of Belief-Motive-Action items about non-drug and drug treatment for hypertension with open-ended question on symptom of hypertension. The summary is as follows: 1) Sixty-one percent of respondents had ever checked their blood pressure somewhere besides the annual screening. 2) Most respondents(97.2%) complained no symptoms of hypertension at all. 3) Belief level of non-drug treatment was relatively high (82.1%-64.7%), but motive(55.1%-28.2%) and action(38.5%-16.7%) levels were low. 4) Belief level of drug treatment was relatively lower than that of non-drug treatment, blue collar workers showed higher artier level of drug treatment than white collar workers, and correlation coefficient between belief and motive on drug treatment was lower in group of not-recognizing their family history of hypertension than recognized group. Such findings indicated that belief on drug treatment of hypertensive workers would be problematic. 5) White collar workers showed significant lower correlation coefficients between Motive and Action of salt restriction, restriction of fatty diet and relaxation than blue collar workers. 6) Mild hypertension group showed low levels of Motive and Action of non-drug treatment(salt restriction, restriction of fatty diet and relaxation) and also showed low correlation coefficient between Belief and Motive of above non-drug treatment.

This study is designed to find out the determinants of dual-earner wives' needs for family-supportive services. For this purpose, a hypothetical model which explains the relationships among 6 stressors, role overload, stress and needs for 4 family-supportive services is developed. Using the data collected by purposive sampling from 234 professional women and 208 blue-collar women living in Chinju and Sacheon, the hypothetical model developed in this study was tested. In order to examine occupational class differences, a model for professionals and another model for blue-collars were developed separately and compared. For data analysis, a covariance structure analysis was used. The best-fitting model for professional women (df=141, GFI=0.928, CFI=0.965) and the model for blue collar women (df=141, GFI=0.902, CFI=0.912) were found. As a result of comparing two models, 9 common relationships were found:l)Greater dissatisfaction with child care service increases role overload; 2)Longer work hours increases role overload; 3) Higher level of role overload increases stress; 4)Higher level of stress increase needs for leaves; 5)Older child increases needs for flexible work pattern; 6)Younger child increases needs for finalcial assistance for child care fee; 7)needs for financial assistance for child care increases needs for on-site child care services; 8)needs for on-site child care services increases needs for leaves; 9)needs for leaves increases needs for flexible work pattern. With the exception of these 9 common relationships, the analyses revealed substantial differences between professional and blue-collar dual-earner wives. Based on the common and differential needs between 2 groups of wives, the effective ways to provide family-supportive services according to the needs of individual dual-earner wives who are in different familial, financial, and work conditions were suggested.

The purpose of this study was to examine the effects of bodyshape and clothing color on boy's impression. The subjects were composed of 480 elementary students, 11-12 years old. The stimuli were consisted of 12 color photographs by using CAD system that was different in the bodyshape, the clothing color and the level of contained color each other. The subjects reported the stimuli's pression on the questionnaires. The image of the stimuli were emerged 5 differented dimensions ; attractiveness, evaluation, potency, bodyshape, visibility. The boy's impressions of normal bodyshape were more attractive, positive evaluation and thin than obese bodyshape. The boy's impressions who was dressed in pink color shirt were thin than blue color. The boy's impressions were positive evaluation when he was dressed in shirt with pink or blue color in collar and cuffs and the whole. The boy's impression of normal bodyshape wearing blue color shirt was the most attractive but the boy's impression of obese bodyshape wearing pink color shirt was not charm. The boy's evaluation who was normal bodyshape wearing pink color shirt was the most positive and the most thin.

The purpose of this study is to study main characters' (Roxie Hart, Velma Kelly) costumes and color images in the movie "Chicago". First, regarding the costumes and color images in characters, Roxie's straight silhouette slip in skin tone reflected her frailty and monotonous routines in reality. On the other hand, a white beaded dress showed her fame-hungry and self-absorption in fantasy. Also, a low waistline blue dress and a see-through black dress with a white collar were to disguise her guilt and draw sympathy to win a suitcase. Black and contrasting colors of red and blue body-suit style dresses expressed Velma's sensual attraction, aggressiveness, and desperation. Second, these images were reinforced by color images in the backgrounds in the film. On the scene of Velma's 'cell block tango', black and red showed her strong character. Contrasting colors of the red and blue expressed Velma's desire and despair in her act of 'the desperation'. As for images of black color on Roxie's stages, they represented her self-absorption and frustration of failing to attract public attention. On the ending of duet performance of Roxie and Velma, the yellow of the background expressed success and joy in life.

Background: Welders are exposed to many known and suspected carcinogens. An excess lung cancer risk among welders is well established, but whether this is attributable to welding fumes is unclear. Excess risks of other cancers have been suggested, but not established. We investigated welding cancer risks in the population-based Canadian Census Health and Environmental Cohort. Methods: Among 1.1 million male workers, 12,845 welders were identified using Standard Occupational Classification codes and followed through retrospective linkage of 1991 Canadian Long Form Census and Canadian Cancer Registry (1992-2010) records. Hazard ratios (HRs) were calculated using Cox proportional hazards models based on estimated risks of lung cancer, mesothelioma, and nasal, brain, stomach, kidney, and bladder cancers, and ocular melanoma. Lung cancer histological subtypes and risks by industry group and for occasional welders were examined. Some analyses restricted comparisons to blue-collar workers to minimize effects of potential confounders. Results: Among welders, elevated risks were observed for lung cancer [HR: 1.16, 95% confidence interval (CI): 1.03-1.31], mesothelioma (HR: 1.78, 95% CI: 1.01-3.18), bladder cancer (HR: 1.40, 95% CI: 1.15-1.70), and kidney cancer (HR: 1.30, 95% CI: 1.01-1.67). When restricted to blue-collar workers, lung cancer and mesothelioma risks were attenuated, while bladder and kidney cancer risks increased. Conclusion: Excess risks of lung cancer and mesothelioma may be partly attributable to factors including smoking and asbestos. Welding-specific exposures may increase bladder and kidney cancer risks, and particular sources of exposure should be investigated. Studies that are able to disentangle welding effects from smoking and asbestos exposure are needed.

Objectives: This study was performed to provide the basic data for establishing countermeasures for preventing injury by analyzing the incidence rates, the risk factors, the characteristics of the injury and the utilization of medical care for mild injury that lasted for two weeks. Methods: We examined the injury survey data among the National Health and Nutrition Survey data. The definition of mild injury that lasted for two weeks was that the injury that caused pain at least once a day for two weeks or the injury for which the usual daily activity of the injured person was severely affected. We used statistical analysis methods such as chi-square test and multiple logistic regression analysis. Results: The incidence rate of injury that lasted for two weeks was 4.7 per 1,000 persons. On the multiple logistic regression, the children and adolescents (OR=3.80, 95%CI=1.63-8.84) had higher rates of injuries than the adults, and the middle and high school (OR=0.51, 95%CI=0.31-0.85) and college(OR=0.34, 95%CI=0.17-0.68) students had lower rates of injuries than the elementary school students. The unemployed (OR=0.39, 95%CI=0.20-0.73) and others (OR=0.38, 95%CI=0.21-0,70) had lower rates of injuries than the blue collar workers. The major causes of injuries were found to be falling and slipping, and the most prevalent place of occurrence was near or at home. Conclusions: A prevention program needs to be developed and continuous education must be offered to the children, adolescents and blue collar workers.

Accident reports from 1991 to 2000 of a steel company were used to analyze which factors induce industrial accidents. The subjects were 8,311 blue-collar workers, who sustained 114 occupational injuries and work on a continuous full-day 3-team 3-shift system of backward rotation(mornings to afternoons to nights). With respect to marital status, the occupational injury rate(OIR) on the married workers was significantly higher compared to unmarried workers. With respect to no, the OIR of those in their early 20s was significantly higher when compared to other age groups. The OIR of highly educated workers showed a reduction when compared with lower educated workers. The OIR of shift workers were significantly higher compared with the daytime workers. The OIR of type of work decreased across the steel manufacturing process, rolling process, machine maintenance section forwarding products section to the field management section. With respect to the block of shift work(morning, afternoon, and night shifts) by the type of work, the OIR of the night shift was higher than those of the morning shift in the steel manufacturing process or forwarding products section. The OIR of the machine maintenance section was slightly higher in the morning shift than those of the night shift. The OIR of the time of day of the shift workers reached a peak between 09:00 and 11:00. The OIR of a slight injury to shift workers decreased across the night, afternoon, to morning shifts whereas the OIR of a serious injury tended to decrease across the night, morning, to afternoon shift. The body parts most commonly injured were the arm and the crus.

Research on employee commitment to the organization is necessary for human resource management, and the result is applied in practice to improve organizational effectiveness. The aim of the present study is to explore factors affecting organizational commitment at the small and medium-sized enterprises (SMEs) in Vietnam. Besides, the relationship between organizational commitment and job performance is examined as well. The research was conducted on a sample consisting of 67 white-collar workers and 260 blue-collar workers at SMEs. A total of 327 valid complete questionnaires were input into SPSS 20 database for processing to provide evidence. The research model and hypotheses were tested using the technique of the hierarchical multiple regression analysis. The research resultsrevealed that income, reward and welfare, direct manager, working environment, coworker, and promotion opportunity tended to associate positively with organizational commitment. Besides, the finding also showed that, when the employee has a high organizational commitment, it would lead to high job performance. The main findings of this study provided some managerial implications for SMEs, in general, and managers, in particular. It implies that Vietnam's small and medium-sized enterprises should improve these six factors to retain employees as well as enhance their job performance.

This paper examines the occupational gender wage gap in the Korea labor market. This paper classifies occupations into three(the blue-collar profession, white-collar profession and female-dominated profession) according to job characteristics and female worker's ratio. To analyze occupational gender wage gap, this paper uses Mincer's wage equation(1974) and Oaxaca model(1973). The results are listed below. First, the gender wage gap is growing in all occupations. Second, the cause of increasing gender wage gap varies in different occupations.

This paper surveys the existing literatures on labor demand of Korea. It has been found that labor and capital are substitutes in Korea and the result holds even if labor is decomposed into white collar and blue collar workers. The elasticity of substitution lies between 0 and 1. It is yet unclear if employment and work hours are substitutes. The reduction of legal work week did not increase employment although decreased work hours. The labor demand elasticity is below 0.5 in the short run. Since mid 1990s, the technological change has shown skill bias and therefore increased demand for skilled labor.
