This paper is concerned with a chronological analysis of the simple limb movement and the performance of a selective response for Korean adults. The cybernetical control number(C.C.No) tester is used to perform the experiment for 103 males and 96 females aged from 20s to above 60s. For the selective response ecperiment, judgement speed has decreased with age. The judgement speed was slowed down more rapidly with age for female than for male. Both the limb movement and the judgement speed showed significantly different trends according to age groups. Especially, it was shown that simple limb movement decreased beginning with 50s for male and 40s for female. It is expected that the results can be applied to the job design of aged people.

The importance of uniform is getting increased in the present society because it is one of symbols which represent a company and give customers the image of it. Uniform shows the kind of companies, one's position, and sometimes the actual job which one does. And workers who put on the same kind of uniform feel companionship among them, the security of their position and responsibility for their job, all of which elevate the efficiency of their job and the company. To enhance the functions of uniforms such as representativeness, esthetics, convenience and economization, the followings were studied. 1) Through survey on the present condition of seven different types of company uniforms, we analyzed preference of workers, staffs and consumers and did the factor analysis of uniform constitution. 2) It presented the relative importance among the uniform constitution. 3) The reflective condition of the uniform constitution was estimated. 4) It investigated the working condition and working movement.

The muscle strengths in various postures are still used in the workplace, although mechanization and automation have been continuously accomplished. The aim of this study is to measure the maximum muscle strength and analyze the muscle fatigue during the various wrench jobs which are one of the upper limbs related works. Four hundreds and eighty five college students (243 males and 242 females) participated in this study. Twelve muscle strengths which are using for pulling, pushing, lifting and lowering the wrench with various postures are measured. For every moment, the muscle strengths for both hands were measured. In each measurement, five seconds averaged value and peak value were collected. The averaged value of preferred hand and non-preferred hand was compared. Also, the averaged value of opposite movement was compared through t-test. The fatigue of agonist for each movement was analyzed using EMG analysis. The result of this study can provide some basic information not only in designing the tools in work but also in selection, training and management of workers.

Purpose: This study was designed to identify the prediction factors that influence nurses' organizational commitment. Method: The sample of this study consisted of 526 full-time nurses randomly picked at 19 general hospitals in Korea. The data was analyzed by computer using SPSS 15.0 for Pearson's correlation coefficient, and multiple regression analysis. Result: 1) According to general characteristics, nurses' organizational commitment levels among the sample were significantly different in age, religion, social status, marital status, clinical career, and department satisfaction. 2) Level of nurses' organizational commitment was average 2.70, job satisfaction 2.91, burnout 3.03, empowerment 3.36, autonomy 2.93, and self-efficacy 3.51. 3) Nurses' organizational commitment had significant positive correlations with job satisfaction, empowerment, self-regulation, social support, self-efficacy, clinical career, and personnel movement experience. On the other hand, it had significant negative correlations with occupational stress, burnout, and age. 4) The prediction factors which influence Nurses' organizational commitment were job satisfaction($\beta$=.405), burnout($\beta$=-.282), self-regulation($\beta$=.171), clinical career($\beta$=.135). These factors were approximately 49.6% reliable in explaining nurses' organizational commitment. Conclusion: These results can be used to develop hospitals' management strategies for increasing organizational commitment effectiveness and nursing productivity.

Kangwonland has been the only domestic casino and movement in casino industry has not been notable, but if more domestic casinos open in the future, it is inevitable those casino workers will move for the better remuneration and working condition. In this situation, in order to keep the previous customers and create new ones, we need to realize the importance of workers who lead customers' satisfaction. For this purpose, we need to find out the influential factors which affect the job satisfaction of the workers and try to turn the worker's satisfaction into good customer service. Despite the importance of casino workers, previous researches about casino industry focused only on economic effects, and there was few systematic research about the casino workers considering their job characteristics who provide services to customers in field. Therefore, this research aims to grasp influential factors of job satisfaction of casino dealers, analyze satisfaction and find out the ways to enhance the satisfaction. This will eventually help profit maximization of the casino company by improving the service quality. For this purpose, research was conducted whether job itself, relationship with the supervisors, promotion, remuneration, working environment affect the job satisfaction of the employees meaningfully and whether job satisfaction changes according to demographic characteristics.

Using the 1st to 13th rounds of occupational history data of the Korea Employment Information Service's Youth Panel (YP2007), this study explores the trends and characteristics of the youth labor market in Seoul. We further empirically investigated the job duration and wage determinants of youth employed in Seoul. The results confirm that workers who have a higher income and a higher consistency with their majors are less likely to leave. In addition, we find that workers in full-time, householders, or labor unions have a higher income if they are men and work in large companies. In particular, compared to the reference group (appropriate academic background, appropriate skill), mismatches in the lack of education and skill showed a wage increase effect of 4.9% and 5.5%, respectively. For the major consistency, the wage of the matched major group is 3.8% higher than the non-matched major group.

The creative class is the class of workers whose job is to create meaningful new forms. Recently, much attention has been focused on the role of the creative class in regional development. Many policy makers have invested to amenities to attract more creative class into their cities or regions for regional economic growth. However, there are only a few studies about the migration of the creative class in Korea. The purpose of this study is to make an analysis of the movement of the creative class by using the 17th Korean Labor & Income Panel Study. According to empirical results, the creative class are more likely to move than the non-creative class. The characteristic of creative class who moved is related to married man aged 20s and 30s without own house. Also, there is the difference between determinants of migration of the creative class and the non-creative class. It was founded that the most important determinants of migration of the creative class are housing related reasons such as home ownership and job reasons. Relationship, convenient facilities are not important factors when the creative class make a decision to move.
