The general n/m job-shop problem is easy to state what is required, but it is extremely difficult to make any progress whatever toward a solution. This paper was first to examine a heuristic procedure of general n/m scheduling generation focused on the procedure of MWRK (Most Work Remaining) presented by Giffler and Thompson (1960) among others. Then modified procedure was proposed to obtain better solution in light of the key measure of performance compared with that of the literature presented by Baker (1974). The modified procedure then has been extended to other example problem to test the better results and to assure the properness of application.

The purpose of this study is to investigate the professional self-concept and job satisfaction of clinical nurses. The subjects consisted of 569 nurses who work at a university hospital and 6 general hospitals in Daegu, Kyungpook and Kyungnam. The findings are as follows : The average item score of professional self concept was 2.68. The mean item scores of professional self-concept in each dimension were as follows: 2.77 for professional practice: 2.33 for satisfaction: 2.91 for communication. The average item score of job satisfaction was 2.79. The mean item scores of job satisfaction in each dimension were as follows: 3.39 for interaction : 3.27 for professional status; 3.19 for autonomy : 2.90 for doctor-nurse relationship: 2.57 for administration: 2.41 for task requirements: 2.16 for pay. The stronger a subject's professional self-concept, the stronger the job satisfaction. The relationship between general characteristics and professional self-concept shows a significant difference with regard to age, religion, marital status, period of nursing career, and position. The relationship between general characteristics and job satisfaction shows a significant difference with regard to age, religion, educational level, work setting, period of nursing career, position, and region. In conclusion, this study suggests that we need to develop a program for improving professional self-concept of clinical nurses through nursing education.

Objectives : The purpose of this study is to examine the relationship between general characteristics and the intention of overseas employment and job satisfaction by Korean dental hygienists. Methods : We conducted a survey of 562 dental hygienists working in dental clinics nationwide. Collected data were analyzed by using the SAS(Version 9.2, SAS Institute, Cary, N.C.) package. $x^2$ test was used to determine the general characteristics of the subjects including job satisfaction level and intention to work abroad. Results : Old aged dental hygienists tended to work in the country rather than abroad(p<0.05). Higher job satisfaction was closely related to working hours, monthly income, social status, and stability of employment(p<0.05). Job satisfaction was concerned with intention to overseas employment. The main purpose of overseas employment included economic benefits(35.99%), self realization(26.75%), and improvement of working condition(21.66%) in the group of overseas employment(p<0.05). The obstacles to overseas employment were mastery of language proficiency(60.94%) and related information(21.89%) in those who want to work abroad. Conclusions : In order to increase the number of Korean dental hygienists for overseas employment, it is necessary to improve working competence and job satisfaction.

Scheduling is one of the most important issues in the planning and operation of production systems. This paper investigates a general job shop scheduling problem with reentrant work flows and sequence dependent setup times. The disjunctive graph representation is used to capture the interactions between machines in job shop. Based on this representation, four two-phase heuristic procedures are proposed to obtain near optimal solutions for this problem. The obtained solutions in the first phase are substantially improved by reversing the direction of some critical disjunctive arcs of the graph in the second phase. A comparative study is conducted to examine the performance of these proposed algorithms.

Purpose: This study was conducted to identify relationships among nursing activities, the use of body mechanics, and job stress in nurses with low back pain. Methods: Participants were 225 nurses with low back pain working at an university hospital. The data were collected with self-reported questionnaires at March, 2012 and analyzed by descriptive statistics, t test, ANOVA, Scheff$\acute{e}$e test and multiple regression analyses. Results: There was significantly a higher degree of pain in subjects who working at special units including intensive care units and emergency room than at general wards. Low back pain was negatively correlated with the use of body mechanical principles while it was positively associated with the degree of job stress. According to results of multiple regression analyses, low back pain was significantly associated with the use of body mechanics and job stress in nurses working at general ward and special units including intensive care units and emergency room. Conclusion: The use of the principles of body mechanics and reducing job stress are important to prevent low back pain in nurses. It is necessary to develop and apply stress management and education program about the use of the principles of body mechanics.

Background: In the present study, we examined gender roles, job satisfaction, and the relationship between the two among orthopedic manual physical therapists (OMT). Methods: The subject of this study was 208 physical therapists working in the general hospital and rehabilitation in Daejeon. In order to examine the nature of the subject, we calculated the ratio of second finger length for fourth finger of predominant hand and completed the questionnaire to determine the general characteristics and job satisfaction. Results: The OMT and NOMT (non OMT) digit ratio results were not significantly different (p>.05). Digit ratio based on gender was also not significantly different between groups (p>.05). Among the job satisfaction survey items, OMT was significantly higher than NOMT in terms of Pride, Reflection of opinions, aptitude match, and field satisfaction (p<.05); however, there were no significant differences between groups for the remaining items. Digit ratio was not significantly related to any of the job satisfaction items (p>.05). Conclusions: We determined that gender roles had a limited influence on selecting and continuing with orthopedic physical therapy.

Purpose: The aim of this study was to investigate and identify work environment, job embeddedness, and burnout among general hospital nurses in Korea. Methods: The participants were 563 clinical nurses working in 13 general hospitals across the country. Data were analyzed using SPSS and Microsoft Excel programs. Results: Mean scores were 2.62 for nurses' work environment, 2.97 for job embeddedness, and 3.61 for burnout. Nurses' work environment showed a positive correlation with job embeddedness (r=.70, p<.001), but a negative correlation with burnout (r=-.49, p<.001). Subcategories of nurses' work environment that predicted job embeddedness included satisfaction and happiness, hospital support for the work environment, patient care environment, satisfaction with work schedule, manager leadership, supportive environment for nurses' work, and computer problems. Subcategories of nurses' work environment that predicted burnout included satisfaction and happiness, violence within ward, hospital support for work environment, and patient care environment. Conclusion: Findings from this study indicate the need to evaluate and improve the work environment for nurses to increase job embeddedness and control burnout. Future studies should explore ways in which turnover intention can be decreased by changing nurses' work environment.

The purpose of the study was to examine job satisfaction, work performance, work satisfaction, perceived needs and self-evaluation of knowledge and skills of nutrition teachers. Survey questionnaire was administered to 106 nutrition teachers in schools of Gyeonggi area. Subjects were categorized into high- or low-job satisfaction group, and study variables were examined by job satisfaction group. Overall job satisfaction was high, with a mean score of 14.9 out of 20. High-job satisfaction group had more favorable perception regarding human relations and workplace atmosphere compared to the counterparts (p < 0.001). Work performance, examined by 12 items, was not significantly different between the two groups. However, satisfaction regarding specific work of nutrition teachers was significantly different by job satisfaction (p < 0.001). High-job satisfaction group responded that they had more knowledge and skills in areas such as food purchase management, food sanitation and safety management, equipment and facility management, nutrition education, nutrition counseling (p < 0.01), and general management & marketing (p < 0.05). High-job satisfaction group also indicated that nutrition teachers need to have more knowledge and skills than the counterparts, regarding food purchase management (p < 0.001), nutrition education (p < 0.01), nutrition counseling, general management and marketing, and teaching practices (p < 0.05). In addition, study results showed significant positive correlations among study variables. This study suggested that job satisfaction of nutrition teachers might be increased by having favorable human relations and workplace atmosphere, increasing satisfaction with specific work of nutrition teachers, and by increasing the knowledge and skills required for the work of nutrition teachers.

The purpose of this study was to analyze social support, job satisfaction and burnout level of Korean nurses who are working in Germany. The data were obtained from 71 nurses in terms of questionnaire which was distributed between October 2000. to January 2001. The analysis of the data was done by means of the SPSS program. The results of this study were as follows ; 1. The subjects had social supporters on the average of 8 to 9. The total social support score was 264.79. An analysis of the relationship between social support and general characteristics for the subjects was found to be statistically significant in the case of religion(t=2.783, p< .05 ) and work experience(F=2.594, p< .05). 2. The mean score of job satisfaction was the highest in interaction(3.71) followed by the relationship between nurses and doctors (3.56), and then followed by autonomy, professional position, pay, requirements, administration in descending order. So the total mean score 3.33 was based on a maximum score of 5. An analysis of the relationship between job satisfaction and general characteristics for the subjects was found to be statistically significant in the case of the thought of the value for the nurse job (F=4.977, p< .001). 3. The mean score of burnout level was 2.94 based on a maximum score of 7. Burnout level was the highest in the order of physical exhaustion, emotional exhaustion and mental exhaustion. An analysis of the relationship between burnout level and general characteristics for the subjects was found to be statistically significant in the case of planning period of employed nursing profession (F=4.113, p< .001), shift of work department (F=2.593, p< .05 ), thought of the value for the nurse job (F=3.789, p< .001). 4. The job satisfaction was found higher as the social support was higher(r= .278, p< .05). The burnout level was found lower as the social support was higher(r= .342, p< .01). The burnout level was found lower as the job satisfaction was higher(r= .478, p< .01). These results discussed on the above indicated that social support influenced on job satisfaction and burnout level, and that job satisfaction influenced on burnout level. To improve job satisfaction for the nurse, it is necessary that the role of social support as well as the method to increase it should be investigated correctly. The study to adjust as well as to prevent burnout level is absolutely needed.
