Purpose: The purpose of this study is to investigate the causes of shifting errors reported in military tracked vehicles and to improve related quality to prevent recurrence. Methods: A systematic disassembly and inspection of the transmission is carried out and an experimental simulation is conducted to reproduce the shifting error phenomenon. Electrical characteristic tests are subsequently performed and microscopic observation is also carried out on the disassembled connector parts such as pins and fractured surfaces. Results: Oil contamination and swelling deformation are observed in the connector to the vehicle due to oil leakage of its counterpart connector to the transmission. This causes electrical contact failure between both connectors in the fastened state, and it is found that shifting error of the tracked vehicle could occur subsequently. To prevent the recurrence of this phenomenon, comprehensive quality improvement is conducted including product improvement of the wiring harness assembly and strengthening activities for quality control and preventive maintenance. Conclusion: This study is expected to be helpful as a prior case study for cause analysis and recurrence prevention in the event of similar cases in the future.

The purpose of this study is to develop a program that allows older women to provide voluntary services for child nursing facilities, making those women have more social participation, effectively their spare time and ultimately improve the quality of their life. Results of the study can be described as follows. First, social requests about the use of older women as volunteers for child nursing services were analyzed to show that most people working at child nursing facilities perceived lack in the number of child nursing teachers. Those people recognized the need of using older women as service volunteers for the facilities. They were very positive about such use. Second, it is recommendable that volunteers of child nursing service should be not too much older women, or below 65. Voluntary activities that those women participate include taking care of younger children, reading interesting stories for children, helping works of child homes, teaching manners and living attitudes, instructing dietary etiquettes and cooking. Voluntary service activities should be made 1 to 3 times a week, 1 to 2 hours a time, considering psychological and physical states of older people. Third, such older volunteers should be educated about 6 areas, 'the operation and management of child homes, 'practices', 'child health and safety', 'the quality of child nursing', 'child development and counseling' and 'voluntary service training'. Out of these six areas, 'child health and safety' and 'voluntary service training' are more required to be instructed. such training needs to focus on activities in which older women can actually engage as volunteers. Fourth, it is advisable that the recruitment and management of such volunteers are led by the city and that the development of training programs for voluntary service activities and education of the volunteers are referred to universities.

Cases of small group activities that were conducted from January, 1996 to December, 1996 in a Korean company (name withdrawn) were analyzed. Eight out of eleven small group activities have been studied. They were examined as to the effect of IT in time and cost savings, reduction in manpower and so on. TQM is the activity of process improvement based on the existing processes in pursuit of satisfaction of customers' needs. This study analyzed how IT was used to solve the current problem in business processes. As a result of the case study, it is found that TQM activities with IT could reduce expenses significantly. More specifically, expenses have been cut down by 56% a year on average. By improving the business processes through the activities of TQM which used IT, companies could remove the unnecessary business processes and the duplicated business processes.

MBNQA(Malcolm Baldrige National Quality Award) was established in 1987 in order to promote the spread of TQM in U.S. Likewise, JQA(Japanese Quality Award) was set up in 1995 in order to upgrade the level of TQM activities in Japan. MBNQA and JQA are quite the same in their basic concepts, values, and the process of the examination, but they differ in the contents of the criteria. The objective of this study is to Identify the differences between MBNQA and JQA in terms of strategy planning category, Therefore, in this paper, strategy planning category is analyzed, especially its theoretical validity is examined by literature review. The major differences are as follows: JQA emphasizes strongly the evaluation process than MBNQA by requiring the measuring of the level of strategic achievement. On the other hand, in MBNQA, strategic objectives must be estimated by decision analysts techniques, scenario tools, and other statistical methodologies.

Purposes: The purpose of this study was to analyze the association between discrimination experience and quality of life among non-regular workers in hospitals. Methodology: The data was collected from 292 employees of 7 university hospitals using a standardized questionnaire. In research methodology, the data was analyzed with descriptive statistics, t-test, ANOVA, pearson's correlation, multiple regression analysis. Findings: In case of non-regular workers, inequality of distribution, position unfairness, employment instability, number of discrimination experiences were found to have a negative(-) effect on quality of life. Religion, income in general characteristics had a significant positive(+) effect on quality of life. And the discrimination of non-regular woman workers was higher and the quality of life was lower than that of men. Practical Implications: These results showed that hospitals needed active efforts to create non-regular woman-friendly work environment. In addition, active religious activities gave emotional stability and positive effect to no-regular workers.

Even though the woollen-yarn-making process as a whole has received much attention from customers in recent years, but yet there exist many problems to improve quality, productivity, and working environment in a small-medium woollen-yarn manufacture. To achieve the aim for improvement of quality and productivity, we have performed a period of education and training for workers. And thus this paper reports a study carried out them in the company located in near Pusan. Also, this paper describes a study how has a small-medium company introduced the education for the workers by authors. Among the possible outcome of this study is that the company does encounter considerable difficulties in the education and training. But to improve the quality and productivity, we assert that the company has to overcome these courses. We all recognize that the employer has been prepared for education and training to improve the employees' working conditions for a long time.
