The purpose of this study was to empirically describe the everyday life of middle-aged adults in terms of their time-use activities. From the original '2004 Time dairy' Data, developed by the Korean National Statistical Office (KNOS), 17,684 respondents aged between 35-59 were selected. In order to categorize their activity patterns, work/labour, domestic labour, and spare leisure time were classified according to the action classification system. As a result, four dominant types were found: namely work-leisure, work-oriented, family-oriented, and leisure-oriented activities. Results of multinomial logistic analysis revealed that gender, age, socioeconomic status, job characteristic, and family structure were the major determinants on time-use. Compared with work-leisure, young middle aged women holding a part-time job with less income tended to be involved in a family-centered time use. Dual earners with lower SES status were likely to have work-oriented time schedules. Older men with relatively lower income were more likely to be involved in leisure-oriented activities rather than work-leisure activities. Multitasking behavior was a significant variable in explaining the four different types of time-use. Work-oriented group showed the highest level of time pressure as well as fatigue. Group differences in these measures, however, was not as large as expected.

The purpose of this study was to find the mediation effect of job satisfaction between job autonomy and career maturity in high school students. It sampled 849 students who have experienced part-time work. Data were analyzed by regression analysis with SPSS 18.0 version. Results showed significant relationships between socio-economic variables(gender, educational aspiration) and main variables. Females showed higher level of job autonomy, job satisfaction, and career maturity than males' ones. Second, job autonomy was a significant predictor of career maturity by gender and educational aspiration. In addition, job satisfaction proved to have a partial mediating effect on job autonomy and career maturity. Based on the results, this study suggest that adolescents actively participate when they work on the field, and employers have to recognize a role of collaborator about vocational education to increase the career maturity of adolescents. Also, communities and schools have to give adolescents right information on job and make an official system to find a good job.

A typical job sequencing problem is studied in this research to improve productivities in manufacturing companies. The problem consists of two-stage parts and assembly processes. Two parts are provided independently each other and then two sequential assembly processes are followed. A new heuristic is developed to solve the new type of sequencing problem. Initial solution is developed in the first stage and then the initial solution is improved in the second stage. In the first stage, a longer part manufacturing time for each job is selected between two, and then a sequence is determined by descending order of the times. This initial sequence is compared with Johnson's sequence obtained from 2-machine assembly times. Any mismatches are tried to switch as one possible alternative and completion time is calculated to determine whether to accept the new sequence or not to replace the current sequence. Searching process stops if no more improvement can be made.

This study aimed to investigate the differences of perceived stigma, psychological empowerment, job satisfaction according to the working hours by latent means analysis(LMA). To get the results, a survey was conducted, targeting employed people with mental illness. Key outcomes of the analysis were as follows. First, it was verified that perceived stigma and job satisfaction, psychological empowerment had statistically meaningful direct relationships. Second, it was analyzed that psychological empowerment had a partial mediating effect in the relationship between perceived stigma and job satisfaction. Third, according to LMA, full-time group showed higher latent mean values on the perceived stigma and lower latent mean values on the job satisfaction. However, part-time group showed lower latent mean values on the psychological empowerment. Based in these results, comprehensive interventions for activating job satisfaction were proposed.

The purpose of this study were to investigate the job analysis questionnaire was mailed to 250 dietitians who are members of The Korean dietetic association practice group in self-operated foodservices(hereafter group A)and 250 dietitians who are employed in contracted foodservice companies(hereafter group B). Completed questionnaires were received from 285 dietitians(121 in self-operated, 164 in contracted) ; a response rate of 57%. Statistical data analysis was completed using the SAS/win packages for descriptive analysis, t-test, $x^2$-test, The results of this study can be summarized as follows. 1. The dietetic training or internship experiences were significantly different between the two sample group(p<.001), but the perceptions of needs for training or internship were not different between and they thought one to six month training would be needed for the job. 2. The question about the time needed in order to perform an expert job was answered significantly differently(p<.001) 3. Group A usually took part in obligatory continuing education and short-term training courses, and group B usually took part in obligatory continuing education and on-the-job trainings, respectively. However both group perceived all three types of educations would be needed for performing the job better. 4. As for the physical demands of the job, a certain degree of accuracy and dexterity for physical tasks and equipment operations was needed for the job. Concerning the mental demands, they answered that their job needs considerable creativity and judgement for planning and performing their tasks was needed. 5. As for responsibilities, group B's responsibilities were heavier than group A’s(p<.001) and need for confidentiality was also greater for group B than for group A(p<.001). 6. As for the supervising role differences, group A rarely received supervision from others and they were given directions only in essential situations, whereas group B was usually supervised when planning and performing their job and tasks, showing significant difference in positions between the two sample groups(p<.001). But each group supervised co-workers and employees in their department. 7. With regard to personal contact, both groups frequently contacted people in their department and other departments at the company and sometimes people outside the company. 8. Concerning the work environment, there were some risks and discomforts in the physical environment and there was no significant difference between the two sample groups.

Since many small and medium sized enterprises in Korea have lack of funds to install a commercial computer packages for work standards and work scheduling. This study has been attempted to develop the computer-generated package to ease those problems. The system consisted of three major parts. The first part is a work measurement program applying W.F.(work factor) predetermined time standards for work standards. The second part is a work scheduling program which calculates each operator's machine and job allocation. The last part is a control program for the production outputs and the machine utilization monitoring. The system is programmed by dBASE III for the IBM-PC compatibles for the sake of user's conveniences.

This paper empirically examines the reemployment pattern (full-time versus part-time reemployment) using pooling 6 year data of Korean Labor and Income Panel Study (KLIPS, 1998-2003). A discrete data analysis (multi-nominal logistic regression) is adopted to identify variables predicting reemployment pattern. Among those who lose full-time or part-time job in previous year, women and older people are found to have both longer unemployment durations and lower probabilities of full-time reemployment (versus either each of part-time reemployment or unemployment) than men and younger people. Therefore, the future labor market policy should be more associated with the one for reducing these gender and age differences in worker characteristics.

Job shop scheduling problem is a complex system and an NP-hard problem. Thus it is natural to look for heuristic method. We consider the multi-part production scheduling problem for quality level in a job shop scheduling under the existence of alternative routings. The problem is more complex if the processing time is imprecision. It requires suitable method to deal with imprecision. Fuzzy set theory can be useful in modeling and solving scheduling problems with uncertain processing times. Li-Lee fuzzy number comparison method will be used to compare processing times that evaluated under fuzziness. This study presents heuristic method for quality level in bottleneck-based job shop scheduling under fuzzy environment. On the basis of the proposed method, an example is presented.

This study was conducted to help develop women's human resources and promote married women's return to workforce. Using various data, we examined the patterns of Korean women's economic activities over the lifecycle, career discontinuation and return to the workforce. We also interviewed twenty full-time housewives who wanted to return to workforce. The interview questions included reasons for seeking employment, desired working conditions, and difficulties in finding a job. Major findings are as follows: First, there were two groups with respect to reasons why they want employment One was an economic need such as earning basic living expenses and supporting the family. The other was self-realization and social participation. Second most women wanted to do unskilled labor such as housekeeping work, whereas some young or well-educated women looked for a professional job. Third, married women preferred part-time jobs, which were compatible with their family care demands. Most of them wanted a workplace located close to home. The women with child-care responsibility preferred working at home. Fourth, regarding difficulties of returning to workforce, they pointed out vocational ability problems due to their career discontinuation, social prejudice such as gender discrimination and psychological pressure in maintaining work and family at the same time. In order to promote employment of married women, it is required not only to change social prejudices but also to increase effectiveness in policy implementation. In addition, counseling for job-search and vocational ability training programs should be provide.

Higher education has become a global phenomenon. Although existing research on the effects of education level have been carried out, most studies were conducted before the year 2000 in a western context. In addition, the research sample was collected mainly from the manufacturing and police sectors. Furthermore, previous studies did not consider various moderating variables. Therefore, this study investigated the direct effect of education level on job satisfaction and the moderating effect of the job position between them. To test the hypotheses, a cross sectional research design with data from a sample of 377 full-time nurses, medical technicians, and administrative staff in one hospital located in the Northern part of Kyunggi province was used. The results showed that the education level was positively related to job satisfaction and job position alleviated the positive relationship between the education level and job satisfaction.
