The purpose of This study is focused on the directions to improve the performance evaluation of cooks working in the primary school by searching for present job satisfaction and job description. Most of the employees' are women-cook and there were no man-cook in school feeding. This fact indicates that the foods which serving by school are not properly developed for the direction of taste and menu variations in the future. Most of married housewives were dissatisfied with long working hours, short break-time, dirty toilet, and other working conditions. And they were also complained of limited job performance in spite of their capacity and knowhow. In order to solve above-mentioned problems, School feeding is, needless to say, very important meal-program for the children and nations, therefore, The authorities concerned give much attention to solve their needs gradually. A real custom that help employees will conducted for the satisfaction of students, If so, really good quality of food service to younger students will be realized.

Evolutionary algorithm is recognized as a promising approach to solving multi-objective combinatorial optimization problems. When no preference information of decision makers is given, multi-objective optimization problems have been commonly used to search for diverse and good Pareto optimal solution. In this paper we propose a new multi-objective evolutionary algorithm based on competitive coevolutionary algorithm, and demonstrate the applicability of the algorithm. The proposed algorithm is designed to promote both population diversity and rapidity of convergence. To achieve this, the strategies of fitness evaluation and the operation of the Pareto set are developed. The algorithm is applied to job shop scheduling problems (JSPs). The JSPs have two objectives: minimizing makespan and minimizing earliness or tardiness. The proposed algorithm is compared with existing evolutionary algorithms in terms of solution quality and diversity. The experimental results reveal the effectiveness of our approach.

PURPOSES : This study was performed to investigate a feasibility of job-site use of recycled concrete aggregate exceeding 3% of absorption rate. Test variables are coarse aggregate types such as natural aggregate, job-site processed recycled aggregate, and recycled aggregate processed from the intermediate waste treatment company. METHODS : First, aggregate properties such as gradation, specific gravity and absorption rate were determined. Next a basic series of mechanical properties of concrete was tested. RESULTS : All strength test results such as compression, flexure and modulus were satisfied for the minimum requirements. Finally up to first 48 elapsed days the shrinkage strains of concretes made from both recycled aggregates (in case of volume-surface ratio of 300) appeared to be greater than 26% of the companion concretes made from natural aggregates. CONCLUSIONS : Drying shrinkage result is ascribed to greater absorption rate and specific gravity of those specimens made from recycled aggregate. This may be reduced with an addition of admixtures.

In this paper load redistribution algorithm to allow fault-tolerance by redistributing the workload of n failure nodes to the remaining good nodes in distributed systems are investigated. To evaluate the efficiency of the algorithms a simulation model of algorithms is developed using SLAM II simulation language. The job arrival rate service rate failure and repair rate of nodes and communication delay time due to load migraion are used as parameters. The result of the simulation shows that the job arrival rate failure and repair rate of nodes do not affected on the relative efficiency of algorithms. If the communication delay time is greater than average job processing time algorithm B is better. Otherwise algorithm C is superior to the others.

The purpose of this article is to depict the organizational effectiveness of "A" Subway Corporation based on the cognitive response of employees(subway drivers). To attain this purpose, several aspects of current personnel aid organization management system and organizational culture are surveyed through questionaire and analyzed by SPSS. The questionaire includes two parts of items. First, it includes items on personnel-related factors such as evaluation system job, wage, role, leadership and job satisfaction. Second, it includes items on organizational culture model suggested by Rousseau. The major findings are : 1) In general the cognitive response of driven concerning personnel-related aspects is to a certain degree negative. 2) The cognitive response of drivers concerning culture-related aspects is awfully negative. 3) Job satisfaction of drivers is highly related to role and leadership factors in terms of personnel-related aspects, on the one hard, and to achievement factor in terms of culture, on the other hand.

Background: Stressed workers suffer from severe health problems which appear to have increased. Poor leadership is especially considered a source of stress. Indeed, supervisors might perceive their subordinates to be similar to them as far as stress is concerned and this might more widespread in organizations than previously thought. Methods: The present research investigates the relationships between leaders' health, in terms of work-related stress, mental health, and workplace bullying and their evaluation of subordinates' stress. Five regression models were formulated to test our hypothesis. This is a cross-sectional study among 261 Italian leaders, using supervisor self-assessment and leaders' assessments of their subordinates. Results: Leaders' health was related to their evaluation of staff stress. Job demand, lack of job control, and lack of support by colleagues and supervisors evaluated in their subordinates were particularly associated with the leaders' own health. Conclusion: Implications for developing healthy leaders are finally discussed.

To examine the psychological characteristics and work ethics of Hanwoo managers, we selected 26 of the 50 managers who took part in this study to avoid unreliable response and non-description from the questionnaire. The core results of this study were the following: First, cronbach's ${\alpha}$ reliability with highest domain in this study were obtained from character strengths (.938), followed by job satisfaction (.841), internal evaluation (.799), and external evaluation (.739). Second, for perception and attitude of Hanwoo management, the correlation between job satisfaction and internal evaluation (P<0.05) was observed. Management satisfaction showed higher for intermediate group and subgroup and lower satisfaction for the top group. Third, there were statistical differences (P<0.05) in ten character strengths (curiosity, judgment, creativity, social intelligence, wisdom, honesty, optimism, responsibility, humor, and passion) according to group satisfaction. Ten character strengths were lower in creativity (7.14) and higher in responsibility (8.57) in comparison with other items for the top group. In conclusion, these results suggest that character strengths are beneficial to improve Hanwoo management on psychological characteristics and work ethics of managers.

This study surveyed how retirees' evaluation of starting food service business affects the effectiveness their new business and quality of life, based on personal factors such as entrepreneurship and business-starting capability and environmental factors by using questionnaires. Bootstrapping was carried out in order to find out factors affecting rapidly changing new business environments and retirees' initial intent to start a business so as to verify basic hypothesis about relation between retirees' evaluation of starting food service business (social, economic, and psychological effects) and the effectiveness of their new business and quality of life and confirm whether the effectiveness of the new business acts as a medium between the evaluation of starting food service business and quality of life. In addition, PLS-MGA was performed in order to verify whether the correlations among test factors can be varied according to the kind of job the target retirees had. Having examined the basic thesis, it was found that social and economic factors had significant positive effect on the effectiveness of the new business, and social and psychological factors had significant positive effect on the quality of life. Having analyzed whether the effectiveness of new business acted as a media between evaluation of starting food service business and quality of life, there was no significant effect as a medium. Having studied whether the kind of job of the retirees controlled or affected the relations among evaluation of starting food service business, effectiveness of new business and quality of life, the results were as follows: in the office job retiree group, the greater economic factor led to increase of effectiveness of new business, while social and psychological factors influenced the quality of life; In the physical labor group, the higher social factor resulted in higher effectiveness of new business, which showed significant positive effect on the quality of life. Having researched about which element is considered to be most important in starting food service business, the most important element was found to be dish/menu, followed by staff management, accounting management, business management, and service education. Having analyzed relation between accomplishment and important consideration for starting food service business, "managers with entrepreneurship," "appropriate distribution of time to prepare for starting business," and "operation of practical field education programs" showed higher importance compared to the degree of satisfaction, so it is needed to more concentrate on the above matters. This study intends to raise retirees' awareness of starting business and help them live better life based on the analysis results, and further suggest detailed mechanism and specific operations of factors affecting retirees' decision making on starting business, such that they can use the information as basic materials to make better choices that can lead to successful business.

This study determined the relationship between organizational conflicts and job satisfaction of administrative staff members employed in university hospitals. The sample consisted of 232 hospital administrators working at four different college hospitals located in D city. The survey was conducted using a self-administered questionnaire during the period from January 10th 2019 to February 15th 2019. As a result of the study, the job satisfaction levels were significantly different according to age, education, BMI, subjective sleep evaluation, subjective health status, job position, monthly income, physical burden of work, sense of satisfaction at work, fit to the job and consideration to quit the job. The job satisfaction levels according to the organizational conflicts were significantly lower with higher organizational conflicts. Further, the job satisfaction level showed a significant negative correlation with organizational conflicts. The risk ratio of lower job satisfaction significantly increased for the group with higher organizational conflict scores than that of the group with lower organizational conflict scores. The results suggest that job satisfaction of administrative staff at university hospitals is significantly related with organizational conflicts. It is necessary to present specific measures to resolve conflicts within an organization in order to enhance job satisfaction for administrative staff at university hospitals.
