The Busan shoe industry has been the accelerating overseas transfer of production facilities due to loss of competitiveness in the wake of drastic revaluation of the won, an increase in personnel expenses and the rise of backup developing countries since the late 1980s. On account of changes in the general system of supply and demand caused by a decrease in exports and production, the Industrial structure has been subjected to a transition from export to domestic demand. As a result, the Busan shoe industry, which used to rank second in the world in terms of its shoe export and to account for 16.5% in terms of its market share, started to be regarded as a fast-fading industry. As a domestic companies have a tendency to almost all the tasks on bloc, it is true that their competitiveness is on the rapid decline for they prefer self-reliance on the premise that all the production should be dealt with for themselves. It is outsourcing that is taken into account as a strategic vehicle for converting such self-reliance into the system of low expenditure and high efficiency.

Mobile hydraulics require higher energy efficiency, and a simpler as well as robust design, than general industrial hydraulics. The 6/3-way directional control valve is widely used as a mobile hydraulic control valve. However, since the 6/3-way directional control valve is a spool type valve, it is difficult to maintain the load. A counterbalance valve is typically used, to maintain the load, and lift down. However, in an industrial field using a mobile hydraulics device, a pilot controlled check valve may be used to implement holding and lifting operation of the self-weight load, and a relief valve may be used simply to exert back pressure. But no comparative analysis of advantages and disadvantages of each method was revealed. In this study, various methods of holding and unloading load with self-weight in mobile hydraulics are investigated, and compared through simulation using AMESim software. This is experimentally verified by using Festo's mobile hydraulic test rig TP800.

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.

This exploratory study investigated the software programs utilized by clinical dietitians and their perceptions on the use of information technology. The study focused on the use of specialized software for dietetics, general software for any office use and the Internet. A self-administered survey was used to collect data from clinical dietitians identified in the Kentucky Dietetic Association Directory 2003-2004. The survey was conducted in March through April, 2004. A total of 22 responses were collected, which yielded a response rate of $68\%$. Findings suggest that computer use has become a routine for optimal clinical practice ; major specialized software programs are used for nutrition assessment, nutrition analysis and menu development. Use of specialized software appears to be unassociated with dietitians' age and years of experience ; however, the associations are indicated between use of specialized software and education level as well as their specialty ; word processing and spreadsheet are the major general software used. Internet is used mainly for information search and communication. Respondents perceived that overall work efficiency and productivity significantly increased with computer use. The complexity of software is the major barrier encountered so training is the most needed support by the department. Strategic promotion on the use of specialized software should be targeted to the management team of the hospitals/facilities.

The purpose of this study is to compar self-reported fatigue and fatigue-regulating behaviors of rheumatoid arthritic patients and normal persons. This study collected the data from 75 rheumatoid arthritic patents visited the departments of internal medicine or orthopedics of four general hospitals T-city and K-city by means of direct interview and questionnaires. in this study also collected data from 75 normal persons who had not been exposed to any other disease in T-city and K-city by means of direct interviews anti questionnaires which were conducted by two trained nurses. This experiment was conducted from August 1, 1998 to October 15, 1998. This study used both MAP(Multi-Dimentional Assessment of Fatigue) developed by Belza(1995) to measure fatigue and the measurement developed by Kwon, Young-Eun to investigate fatigue regulating behaviors. The collected materials were analyzed by means of descriptive statistics, t-test, and the ANCOVA according to the SPSS PC+ program. The findings are as follows : 1. There was the statistically significant difference(t =5.07, p=.000), between rheumatoid arthritic patients(32.76 points) and normal persons(25.81 points) in t-test comparison by group about fatigue. A fatigue degree of rheumatoid arthritic patient group was high in five kinds of lower realms such as common fatigue degree, fatigue severity to be experienced, distress due to fatigue, daily fatigue degree, and fatigue timing at the last week by dimension. 2. There was the significant difference in the number of fatigue-regulating behaviors between rheumatoid of fatigue arthritic patients(9.37 times) and normal persons (8.15 times), but there wasn't any significant difference in the efficiency between rheumatoid arthritic patients(2.85 points) and normal persons (2.78 points) This research suggests two kinds of things as follows : 1. It is necessary to develop an educational program for improving efficiency of fatigue-regulating behaviors as well as some nursing arbitration measures for reducing fatigue of rheumatoid arthritic patients. 2. It is necessary for the future studies to continuously grasp characteristics of fatigue by gender variable by selecting more rheumatoid arthritic male patients.

As a cross-sectional study, this study was aimed to investigate and compare the job efficiency and satisfaction of nurses according to the hospital grade. Survey was conducted by mail on June 2009, and the respondents were 1,016 nurses working in 15 hospitals which are 9 high-grade general hospitals and 6 general hospitals. The percent of nurses acknowledging their hospital grades is 34.5%, and that is 20.5% at high-grade general hospitals. As the result of review of studies, it is concluded that under the circumstance that differential rates are contracted to calculate fees for hospital services and copayment of patients are according to nursing grades and hospital grades, the degree of nurses' awareness of insurance fees impact on their performance like recording of care and prescription. In order to improve nurses' performance, they need to be educated about the national insurance fee system. In hospitals with higher nursing grade and more beds, the levels of nursing quality and faithfulnes and their job satisfaction were higher. Nurses' awareness of their hospital nursing grade was related to the quality of nursing but not the faithfulness. Nurses working in higher nursing-grade hospital are more self-respect and satisfied at their jobs, and their job efficiencies are not significantly different. The current nursing fees based on the proper number of nurses per beds of nursing units should be changed to be based on the amount of job per nurse by their nursing protocol, and the nurse staffing standard should be differentiated between nursing grades. As the aspect of nursing, 24-hours patient care, it is difficult to improve nurses' job satisfaction, and in the other hand, that tends to depend on their income level. In the current circumstance, comprehensive research is required to investigate the propriety of 25% of the inpatient fees as the nursing management charge.

Objectives : The purpose of this study was to examine the relationship of the self-efficacy of dental hygiene students to their stressors and ways of stress-adaptation patterns. Methods : The subjects in this study were dental hygiene juniors in four selected colleges located in the metropolitan area. Results : 1. They got a mean of 3.22 in self-efficacy. They gave the highest mark(3.50) to an item 'I can attain it if I set a primary goal.' 2. They got a mean of 3.18 in stressors. Among the stressors, task assignments(3.74) were identified as the greatest stressor, followed by the curriculum(3.25), learning environments(3.16), prospects of employment (3.07) and test anxiety(2.95). 3. They got a mean of 2.02 in stress-adaptation method. They got 2.31 and 1.72 in long-term and short-term adaptation respectively, which showed that long-term stress adaptation method were more prevailing than short-term ones. 4. As a result of analyzing whether there would be any gaps in self-efficacy according to general characteristics, statistically significant gaps were found in that regard according to experience of preparing for college admission after leaving high school, academic standing, satisfaction with the department of dental hygiene and prospects of employment(p<.05). 5. As a result of checking the relationship of their self-efficacy to their stressors and ways of stress adaptation method, there were statistically significant differences in that aspect according to examinations and prospect of employment(p<0.05). As for ways of stress adaptation method, there were statistically significant differences in long-term adaptation method (p<0.05). Conclusions : As it's found that the level of the self-efficacy of the dental hygiene students was linked to the efficiency of their ways of stress adaptation method, the development and implementation of programs geared toward boosting the self-efficacy of dental hygiene students are required to teach them to successfully cope with various kinds of stress that they are likely to face after getting a job.
