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.

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.

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.

본 연구의 목적은 실업자의 재취업여부와 재취업형태에 영향을 미치는 주된 요인이 무엇인지를 파악하는데 있다. 이를 위해 본 연구는 한국노동패널의 6개년(1998-2003) 결합자료를 이용하여 사건사분석의 생존표분석과 이산시간분석을 실시하였다. 분석의 결과, 성, 연령, 교육수준이 실업자의 재취업과 재취업형태에 영향을 미치는 주요 요인으로 파악되었다. 또한 정규직과 비정규직으로의 재취업형태는 실업자의 이전 직장 업종과 직종에 따라 상이한 결과를 보이는 것으로 나타났다. 이러한 결과에 비추어 볼 때, 우리나라 실업자의 재취업과 재취업형태는 실업자의 인적자본 수준보다는 분절된 노동시장의 구조에서 기본적인 원인을 찾을 수 있을 것이다. 결국, 실업자의 재취업과 보다 안정적인 고용형태로의 재취업을 도모하기 위해서는 성과 연령에 의한 차별의 폐지, 직업능력개발훈련의 강화, 그리고 효율적인 노동시장 정보체계의 구축 등의 정책적 접근이 필요하다.

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.

전 세계적으로 고학력화는 만연한 현상이며 점점 더 심해지고 있는 추세이다. 고학력의 효과성에 대한 많은 연구들이 발표되고 있지만, 주로 2000년대 이전의 연구가 많고 진행된 연구도 서구권 국가를 대상으로 진행되었다. 또한 제조업 및 일부 공공영역(예; 경찰)을 주된 표본으로 사용하였고, 다양한 조절변수를 다루지 못한 한계점이 있다. 이러한 상황에서 학력과 조직행동 연구의 중요 변수인 직무만족과의 관계 및 그 관계에서의 조절효과를 살펴보는 것은 의미가 있을 것으로 생각된다. 이에 본 연구에서는 조직 내 인력이 기업의 성과에 크게 영향을 미칠 수 있다고 생각되는 병원 근로자들을 대상으로 최종 학력이 직무 만족에 어떠한 영향을 미치는지 그리고 상황변수인 직급이 이들 간의 관계를 어떠한 방향으로 조절하는지에 대해 분석하였다. 연구문제를 검증하기 위해 경기북부의 1개 병원에서 근무하고 있는 377명의 간호사, 의료기사, 행정직의 자료를 실증분석 하였다. 회귀분석 결과 최종 학력은 직무만족과 정의 관계를 가지는 것으로 확인되었으며, 개인의 직급이 높아질수록 최종학력이 직무만족에 주는 긍정적 관계는 완화되는 것으로 나타났다.
