This study was attempted to suggest fundamental data to take health care plan in terms of oriental medicine by evaluating the health-related quality of life according to the Sasang constitutional medicine (SCM) of factory workers. General characteristics, living habits, and health-related quality of life were investigated through self-administration questionnaire in the course of oriental health examination for 1,870 male workers at a manufacturing company located in the Jeollabuk-do region, and the Sasang constitution of each worker was identified and analyzed through questionnaires and oriental doctor's medical examination. For Sasang constitutional medicine, So-eum person(少陰人) was found to be the most, and then So-yang preson(少陽人), Tai-eum preson(太陰人), and Tai-yang preson(太陽人) in order; for lifestyle, smokers were most found in So-yang person workers, non-smokers in Tai-yang person workers, drinkers in Tai-yang person workers, and non-drinkers in So-eum person workers. For the general health score by the Sasang constitutions, Tai-yang person workers were found to be 42.73 in general health area, Tai-eum preson workers 41.69, So-yang person workers 40.87, and So-eum person workers 40.42; in the vitality area, Tai-eum person workers were found to be 45.14, So-yang person workers 44.16, So-eum person workers 43.02, and Tai-yang person workers 41.34. Specially, it was found that regular exercise improved physical health factors, drinking adversely affected mental health factors, and the mental health factors of Tai-eum person workers who have regularly exercised showed the highest values, while those of Tai-yang person workers who have not exercised showed the lowest values. There was difference in lifestyle by Sasang constitutions, and accordingly, the quality of life might be different Therefore it is deemed that health care plan is required to be taken by Sasang constitutions and lifestyle for health promotion and care of blue-collar workers in the future.

This study was performed to elucidate the association of blood pressure and incidence of hypertension in response to changes in body mass index. A total of 28,249 industrial workers (male: 25,548, female: 2,701) who aged 30~69 years old, received regular medical check-up at least once per year from 2002 to 2012 (over 11 years) were included. In the analysis, the averages of blood pressure were stratified by BMI which was obtained from the initial examination results of each individual. In addition, averages of changes in blood pressure were analyzed by stratifying with changes in BMI over 10 years(from 2002); annual occurrence rates of high blood pressure, stratified per BMI, were further assessed in which patients were in normal ranges of blood pressure. As a result, the averages blood pressure over 10 years were more significantly elevating in the group of obesity compared to those of the low weight group as well as the normal weight group. Similarly, when it comes to the occurrence rates of high blood pressure, the group of higher BMI represented elevated risks compared to the groups of low BMI. In conclusion, the increase of BMI over 10 years(2002-20012) were significantly influenced on the increase of blood pressure.

The purpose of this study was to analyze a change in Post-traumatic Stress Disorder (PTSD) level and the continuity of the effects in music therapy by applying short-term music therapy program in fire fighters with Post-traumatic Stress (PTS). Forty two fire fighters in 3 districts were randomly assigned to experimental group (21 subjects) and control group (21 subjects). Music therapy was applied in totally 10 sessions by two sessions (120 minutes) a day for 5 days. PTS level was measured immediately after the end of program, after 4 weeks, and after 12 weeks. As a result, PTS level has significantly decreased into $8.90{\pm}4.55$ from $26.52{\pm}2.32$ right after the music therapy program(p<0.05). And the effect was shown to be continued significantly up to after 4 weeks($11.95{\pm}4.57$) and after 12 weeks($13.76{\pm}5.62$)(p<0.05). As a result of research, it is considered that the music therapy is effective approach for reduction in PTS as for fire fighters who belong to the group with high risk of PTSD. Accordingly, the application of regular program for managing fire fighters' mental health is understood to likely to contribute to enhancing the field service competence.

This study was conducted to determine the quality of sleep, and its association with the sociodemographic characteristics, health-related characteristics, and job-related characteristics among male workers in small-scale manufacturing industries with fewer than 50 members. A self-administered questionnaire was distributed to 856 male workers from April $1^{st}$ to June $30^{th}$, 2011. The survey items included the variables of sociodemographic, health-related, job-related, and quality of sleep. As a result, the quality of sleep according to the PSQI of the study subjects revealed 32.0% to be good and 68.0% to be poor. The quality of sleep assessed by hierarchical multiple regression analysis was significantly lower in the married group, those with lower BMI, and those with a lower level of subjective health status, non-smoking, alcohol drinking, without regular exercise, coffee drinking, blue color, had a longer of working hours, subjective health status, had a visiting out-patient department, and had a history of hospitalization. With the above model, the job characteristics had 13.1% explanatory power. This suggests that the quality of sleep (PSQI) has more power when combined with the job characteristics.

This study was conducted to find out the complaint rate of musculo-skeletal disorder and its related factors from male manufacturing workers at a nonferrous manufacturing industry. As for the research subjects, 302 workers selected from a nonferrous manufacturer located in Daejeon City, and as for the collection of data, a standardized anonymous questionnaire survey were conducted from May 1, 2011 to June 30, 2011. As a results, the complaint rate of musculo-skeletal disorders by each body part, the symptom of shoulders was 42.7%, the highest rate, followed by the waist, 36.8%, the neck and the hand/wrist/finger, 30.5% respectively, the leg and foot, 30.1% and arm/elbow, 20.9%. The complaint rate of musculo-skeletal disorder for the sociodemographic characteristics was significantly high as survey participants' age and BMI were low and in the group having low subjective health condition. The complaint rate of musculo-skeletal disorder for the health-related behavior characteristics was significantly high in the group having been absent from work due for diseases, in the group having received outpatient services, in the group having been hospitalized for treatment, in the group not having a regular exercise and in the group having insufficient sleeping hours. Finally, the complaint rate of musculo-skeletal disorder for the job-related characteristics was significantly high in the group suffering from the physical burden of their work, in the group working while bending at the waist and in the group carrying out repetitive tasks.

Objectives: Although the number of laboratory workers is constantly increasing every year, few studies have been conducted on the health and nutritional status of these research workers. This study determined the health status of laboratory workers by analyzing their anthropometric indices, dietary life, vitamin D status and blood clinical indices. Methods: The subjects consisted of 100 female laboratory workers. This study investigated their diet, anthropometric indices, vitamin D status and blood clinical indices. The subjects were divided into two groups according to their duration of working in a laboratory (<1 year, $${\geq}_-1year$$). Results: The average age and body mass index (BMI) of subjects were 23.18 years and $21.51kg/m^2$, respectively Those subjects with over 1 year employment ($${\geq}_-1year$$) had a significantly higher waist-hip ratio than that of the subjects with the less than 1 year employment (<1 year). The mean serum vitamin D level of all the subjects was 10.04 ng/mL, which is close to a level of vitamin D deficiency. There was a significantly higher average intake of calories in the over 1 year employment group as compared to that of the less than 1 year employment group. The frequency of eating sweet snacks was significantly higher for the over 1 year employment group. The correlation analysis showed a significant positive correlation between the serum 25-(OH)-vitamin D level and the time of exposure to sunlight, while dietary intake of vitamin D did not show correlation with the serum 25-(OH)-vitamin D level. However, the serum 25-(OH)-vitamin D level was also negatively correlated with both the percentage of body fat and visceral fat. Conclusions: Laboratory workers are a very high risk group in terms of their nutritional status of vitamin D. Therefore, they need greater time of exposure to sunlight as well as increasing their dietary consumption of vitamin D. In addition, it is important for laboratory worker to practice regular and balanced dietary habits in order to maintain a healthy life.

This study aims at explaining organizational mechanisms of inequality that has been rising rapidly alongside the proliferation of irregular employment in the post-crisis Korean labor market. It argues that inequality is not sufficiently explained by individual gap in human capital or widespread marketization as such. Social categories into which each individual worker falls seems more important as a source of labor market inequality. Employment types that are composed of regular and irregular employment do not simply indicate the different economic meanings of employment contracts but have rather been institutionalized as a social category of status in the context of inequality over the past two decades. They are also often matched with other social categories such as gender that have created and reproduced greater labor market inequality. We pay attention to the organizational practice of dominant incumbents who make claims for advantages of return based on their exclusive accessibility to limited organizational resources and explain how that particular practice plays a role to increase relational inequality between those insiders who achieve advantageous returns and outsiders mostly irregular workers who are excluded from those resources because of the social categories that they belong to. In this study, we identify seniority based pay as the key organizational practice that justifies categorical differences within the workplace and examine how that particular practice contributes to organizational level segmentation and income ineqaulity.

This study was conducted with the purpose of deriving a revitalization plan by analyzing the factors influencing the characteristics and perception of self-employment and self-employment selection of young people. To this end, discussions on self-employment and the size of workers were reviewed, and the characteristics, determinants, and difficulties of self-employment youth were analyzed based on data from a survey of youth in Seoul and Gyeonggi-do. The support plan proposed through the analysis should first strengthen the program so that the government, local governments, and schools can all gain experience in the practice of developing ideas, producing, and selling based on aptitude and competency to solve youth employment problems. Next, compared to support for technology-based start-ups, there are no suitable programs in the fields of knowledge, manufacturing, and distribution, and there is almost no support for freelancers in which the majority of young people are engaged. Therefore, it is necessary to diversify support projects so that the diversity of young people can be expressed in self-employment. Finally, it was found that entrepreneurship had an important influence on self-employment. However, Korean teenagers do not know what entrepreneurship is and have no experience in education, so they should focus on cultivating entrepreneurship in the regular curriculum and establishing a cultural foundation to foster young leaders with creative ideas and execution.

Purpose: The Ministry of Employment and Labor has been working hard to ensure the safety of workers due to heavy rain during natural disasters as the responsible ministry in charge of preventing industrial accidents and health problems for workers. Accordingly, the Ministry of Employment and Labor intends to analyze actual cases of responding to heavy rain disasters and suggest ways to improve the response system. Method: An emergency response system implemented to respond to heavy rain disasters with an internal expert group composed of those in charge of disaster work at headquarters, local government offices, and Korea Occupational Safety and Health Agency, and an external expert group composed of professors, consulting representatives, and disaster managers from other ministries. Contents on self-inspection by industry, workplace inspection, use of serious siren, safety management and restoration work guidance were reviewed. Result: First of all, it is necessary to check the regular contact system from time to time, and it is also necessary to prepare and distribute detailed self-checklists for each industry. In addition, it is necessary to check the implementation of self-inspection when inspecting workplaces, and it seems necessary to have measures to increase the readability of information notified through serious disaster sirens. In addition, since safety work is done in the form of a contract, it seems necessary to prepare specific safety guidelines. Conclusion: In order to protect the lives of workers due to seasonal harm and risk factors, unlike the passive coping methods of the past, abnormal weather should not be regarded as an unexpected situation, and it should be actively and preemptively responding beyond the conventional framework.

The present study examines the dialectic tensions arising within the ICT-mediated labor culture between the dominant power of conglomerates and the precarious labor subjects in the labor practices, as smartphones and tablet PCs have grown in popularity. The present study explores how much young precarious workers named 'Cheongyeon Alba' (young precariat in S Korea) suffers from continually precarious job positions as temporary staff or contract workers, being trapped at the bottom of the pay scale, and also being electronically connected to the workplace in a seamless way. Concretely, this study investigates how the mobile phone becomes deeply entangled with the 'precarious' labor culture in the metropolitan city of Seoul. The mobile precariat has been in a disadvantaged position, in terms not only of the moral issue of exploitation in business but also of social injustice. Labor exploitation of young workers has been reinforced by the mobile labor culture, in which they are remotely monitored by live surveillance mobile apps, and mobile instant messaging from a boss can intrude incessantly into their private life. This study depicts the extension of the business's surveillant power by mobilizing the mobile phone in the working practices.
