The paper is devoted to some flow shop scheduling problems, where job processing times are defined by functions dependent on their positions in the schedule. An example is constructed to show that the classical Johnson's rule is not the optimal solution for two different models of the two-machine flow shop scheduling to minimize makespan. In order to solve the makespan minimization problem in the two-machine flow shop scheduling, we suggest Johnson's rule as a heuristic algorithm, for which the worst-case bound is calculated. We find polynomial time solutions to some special cases of the considered problems for the following optimization criteria: the weighted sum of completion times and maximum lateness. Some furthermore extensions of the problems are also shown.

The aim of this study is to analyze determinant factor on the strike action among hospital laborer in Korea. We collected data for 10days from 12 to 22 July, 2013. This study was surveyed 405 laborer in university hospital was located in the Seoul city and Gyeonggi-do. It was found as follow. There was statistically significant difference in the strike propensity and sub-domain on the job dissatisfaction by sex, age, education, wedding, occupation, position, salary, number of years of employment, position in labor union for strike action(p<0.05). From the multiple regression analysis, it was found that determinant factor on the strike action was occupation, strike propensity(sense of duty, after vote, depend on compensation) which was statistically significant difference(p<0.05). As a result, we suggest that hospital administrator must solve the problem related welfare benefits and personnel system in university hospital for preventing strike.

Organizational personnel must have well-developed interpersonal skills to deal with the different stakeholders and departments, to work at different levels in the hierarchy, and to meet varying performance requirements. Many leadership development and mentoring programs are designed to expose students as well as construction professionals to contemporary leadership techniques and skills. Leadership skills generally separate into three decision-making styles with varying degrees: 1) Autocratic, 2) Participate, and 3) Free-rein. This paper describes the study of leadership styles among 174 construction professionals and addresses the most appropriate leadership style for a project executive and a project manager in relation to compare with the characteristic leadership style and job functions. The study supports the growing importance of leadership skills as a component of managerial functions and provides a benchmark to identify a dominant leadership skill for a specific managerial position.

본 연구의 목적은 지도교육자의 직무가 컴퓨터 경험, 지식, 태도, 사용에 미치는 영향을 구명한 후 지도 교육 시스템에서 컴퓨터 연수 프로그램을 직무에 따라서 그룹화하여 실시하는 것이 적절한 방법인지 그 타당성을 조사하는데 두고 있다. 연구방법은 중다변인변량분석(MANOVA)에 의해 이루어졌다. 연구 결과에 의하면 이들간에는 통계적으로 유의한 관계성이 있다고 나타나며, 따라서 컴퓨터 연수 프로그램을 설계시 직무는 고려해야 할 중요 변인으로 여겨진다. 한편 직무에 따른 참가자들의 그룹화는 쉽게 이루어 질 수 있으므로 실질적인 측면에서도 설계자들이 고려해야 할 요인으로 여겨진다.

Gaze detection is to find out the position on a monitor screen where a user is looking at, using the image processing and computer vision technology, We developed a computer interface system using the gaze detection technology, This system enables a user to control the computer system without using their hands. So this system will help the handicapped to use a computer and is also useful for the man whose hands are busy doing another job, especially in tasks in factory. For the practical use, command signal like mouse clicking is necessary and we used eye winking to give this command signal to the system.

This study was done to identify the influence of emotional labor, job stress and burnout on somatization of nurses live in convergence era. The participants were 387 nurses in D hospital. The average mean score for emotional labor was 3.25, occupational stress was 3.60, burnout was 3.10, and somatization was 2.18. For relations with general characteristics, there was a statistically significant difference in somatization according to age, marital status, educational level, work unit, total clinical career, present department career, position, monthly salary, shift and job satisfaction. Somatization was found to be in a significant positive correlation with emotional labor, occupational stress and burnout. As a result, factor influencing somatization was burnout. This predictor accounted for 29.6% of variance in somatization. The findings of this study showed that burnout was major influencing factor on somatization of nurses. Therefore, it is necessary to develop strategies that can reduce somatization by controlling burnout.

This study examines the factors that influence the chance of getting a full-time tenure track? position in universities in biochemistry. Its main findings are: first, as age at the time of getting a Ph.D. degree increases and the more recent a birth-cohort a female Ph.D. belonged to, the more likely she was likely to get a job; second, the number of citations of publications in science-citation indexed journals during a Ph.D. program period and the number of publications in science-citation indexed journals in post Ph.D. period increased her chance of getting a job; third, a post doctoral program and the duration of Ph.D. training did not affect a chance of getting a job; finally, a Ph.D. from a foreign university and a prestige ranking of a Ph.D. program did not influence a chance of getting a job.

In order to obtain basic data for a health promotion program of hair dressers, the health promoting behavior of some hair dressers was assessed with the related factors such as general characteristics and cognitive-perceptual factors. The subjects were 245 hair dressers working at beauty shops having at least two hair dressers. The data was collected by a questionnaire from October 14 to October 20, 2001. The results were as follows： 1. The mean score of health promoting behavior conducted by the hair dressers was 31.17 out of 50.00 in total score. 2. The score of the health promoting behavior was statistically different according to marriage, on-duty hours, holidays, satisfaction in the job, perceived health status, perceived fatigue, health concept, and self-efficacy (p＜.05), while it was not statistically different according to gender, religious faith, residence, eduation, economic levels, career in the job, average income, medical care insurance, employment insurance, control of fortuity, and control over other persons. 3. The health promoting behaviors in the hair dressers showed positive correlation with self-efficacy and internal control, while it showed negative correlation with control over other people, control of fortuity, health concept, and perceived fatigue. 4. The Regression analysis results of the questionnaire showed that perceived fatigue, health concept and office hours were significant factors but the age, the fact of being single or couple, position at the job, holidays, satisfaction of the job, self-control and stresses from other people and self-efficiency appeared insignificant. In conclusion, the hair dressers with less perceived fatigue and better cognitive health concept and short duty hours showed better health promoting behavior. So, In order to conduct health promoting behaviors of hair dressers, the method will need to control of working time and perceived fatigue.
