Purpose: The purpose of this study was to identify the factors influencing fatigue in patients with chronic obstructive pulmonary disease. Methods: A descriptive correlational study design was used. A convenience sample of 125 subjects was recruited from the outpatient respiratory clinic at a large university hospital. Data was collected from June to October, 2005 using structured questionnaires, an oxygen saturation test, a 6-minute walking test, and a pulmonary function test. Results: Subjects had a slightly low degree of fatigue. The fatigue showed a significant correlation with emotion(r=.589, p= .000), dyspnea(r=.304, p= .001), self-efficacy(r=-.278, p= .002), and symptom experience(r=.238, p= .008). Emotion(34.7%) and dyspnea(5.8%) were significant predictors to explain fatigue. Conclusion: This study provides comprehensive understanding of the influencing factors on fatigue in patients with chronic obstructive pulmonary disease. Nursing interventions to decrease negative emotion and dyspnea for management of fatigue is suggested.

The purpose of this study was to investigate familism and materialism of the Korean-Americans. A total 370 subject completed structured questionnaires. Major conclusions of this study are as follows: First, the Korean-Americans are found to support familism below average. But subgroup differences (according to age, for example) were discovered. Second, the Korean-Americans are found not to support materialism. But, like familism, subgroup differences by several variables were discovered. Third, among the Korean-Americans, the urban Koreans and the rural Koreans, the rural Koreans are found to support familism most strongly. But theres no difference between the Korean-Americans and the urban Koreans. The Korean-Americans are found not to support materialism.

The purpose of this study was to investigate the level of assets and liabilities of farm households and to evaluate the financial status of rural middle-aged and old-aged household using financial ratios. For these purposes an empirical survey data was gathered from rural middle-aged and old-aged households in 8 provinces using structured questionnaires. 877 households data were used in final analysis. The statistical methods used for data analysis are frequency percentile mean The statistical methods used for data analysis are frequency percentile mean median standard deviation $\chi$2 and t-test using SPSS/PC WIN program. Among financial ratios 64.7% of total households could meet the guideline of consumption to income ratio 5.9% of total households could meet the appropriate level of short-term and long-term liquidity. In the case of debt burden ration 82% of total households could meet the guideline. And 28.5% of total households could meet the guideline of capital stock ratio .

The main purpose of this research was to examine the variables that influence environment-friendly management behaviors of family resources. For this study, environment-friendly management behaviors were classified into four categories: buying, using, recycling and disposal. Another purpose of this study was to find out the levels of environmental education, environmental knowledge, and environmental consciousness among household managers. In order to determine the levels, a structured survey questionnaire was administered and data were collected from 391 housewives who live in Seoul and Jeonju. The results show that environmental consciousness and environmental knowledge affected buying and disposal behavior. There was a significant difference in using behavior by the degree of environmental consciousness. The variables that affected recycling behavior were environmental education and environmental consciousness. The level of environmental awareness was highest in ! environmental consciousness, second highest in environmental knowledge, and lowest in environmental education.

The purpose of this study was to explore marital violence from a communication perspective. A total of 352 marital couples in Pusan completed a structured questionnaire. The major findings were as follows: 1,. Husbands and wives reciprocally inflicted psychological aggression and physical violence. But husbands were more to inflict sexual violence and injury toward their wives. 2. When husbands have more the distractor and the blamer of communication style. they inflicted more physical violence toward their wives. When wives have more the blamer of communication style they inflicted more psychological aggression and physical violence toward their husbands. 3, Housbands inflicted psychological aggression toward their wives when husbands experienced child abuse from their parents. husbands inflicted physical violence toward their wives when husbands have the distractor of communication style experienced witness of spousal violence between father and mother and experience of scho l violence experience in the middle and high school. Wives inflicted psychological aggression toward their husbands when wives experienced witness of spousal violence between father and mother and have the blamer of communication style. Wives inflicted physical violence toward their husbands when wives experienced child abuse from their parents.

Purpose . The purpose of this study was to investigate the stress level and sleep type on university students at health series. Method . This research conducts a survey of 250 university students on health series. The research tools were structured questionnaires. The questionnaire about stress was measured using psychological stress questionnaire in life stress and sleep type was measured using the Korean Translation of Composite Scale of Measuring Morningness-Evening. Result . In this study, university students 16.4% of the students were at warning. The morning sleep types were 55.2% in all health series university students but slee type was not in the most of sleep type. There were not correlation between the sleep type and stress level. Conclusion . It is seems to need to management of stress on university students at health series.

This paper describes study results on the development of an automatic program for generating surface-panel grid for the aircraft optimal design. The aerodynamic analysis is combined into a PIDO tool in conjunction with a number of programs in order to integrate processes for the optimal design. Due to design optimization's iterative feature, it may require lots of time and cost. To relieve this problem, cost-reduction of computation time for aerodynamic analysis is pursued by using the Panel-method, and reduction of grid generation time by automating surface panelling.

A methodology for the simulation of compressible high Reynolds number flow over rigid and moving bodies on a structured Cartesian grid is described in this paper. The approach is based on a modified version of the Brinkman Penalization method. To avoid oscillations in the vicinity of the body and to simulate shcok-containing flows, a Weighted Essentially Non-Oscillatory scheme is used to discretize the spatial flux derivatives. For high Reynolds number viscous flow, two turbulence models of the two-equation Menter's SST URANS model and a two-equation Detached Eddy Simulation are implemented. Some simple flow examples are given to assess the accuracy of the technique. Finally, a moving grid capability is demonstrated.

The objective of this study is to provide a simple methodology to find optimum processing conditions to fabricate sub-micron structured DVD-RAM substrates with superb optical and geometrical properties. It was found that the birefringence, which is regarded as one of the most important optical properties for an optical disk, was very sensitive to the mold wall temperature history. Also, the integrity of the replication, represented by the land-groove structure and the radial tilt were influenced by the mold temperature and the compression pressure. A set of optimum conditions were obtained by applying Design of Experiment and the objective functions composed of three different objectives.
