The purpose of this study was to explore decision making phenomenon of living kidney donation experienced by kidney donors. Data were collected through semi-structured indepth interviews from 12 kidney donors. All interviewes were audiotaped and transcribed verbatim. Constant comparative analysis was used to analyze the data with NUDIST4.0 software program. process have effects on the execution of kidney donation. Based on the degree of "wish to give", three distinct patterns were identified: Voluntary, compromising, and passive. The voluntary decision making was the most frequent one, while the passive the least. The degree of "wish to give" was influenced by intimacy between the donor and the receipient, geographical locations, economical efficiency of kidney transplantation, and religion. Each pattern was explained by describing interfering and facilitating factors as well as other issues occured in the decision making process. The results of this study will help nurses make effective nursing intervention by understanding the characteristics of decision-making patterns and decision-making process to donate a living kidney.

Understanding and adapting to changes of customer behavior is an important aspect for a company to survive in continuously changing environment. The aim of this paper is to develop a methodology which detects changes of customer behavior automatically from customer profiles and sales data at different time snapshots. For this purpose, we first define three types of changes as emerging pattern, unexpected change and the added / perished rule. Then we develop similarity and difference measures for rule matching to detect all types of change. Finally, the degree of change is evaluated to detect significantly changed rules. Our proposed methodology can evaluate degree of changes as well as detect all kinds of change automatically from different time snapshot data. A case study for evaluation and practical business implications for this methodology are also provided.

Criticisms about amyloid cascade hypothesis of Alzheimer's disease(AD) are based on the findings, first, that the degree of dementia does not correlate with the number of plaques, and second, that the neurofibrillary tangle formation seems to predate plaque formation. In addition, neurofibrillary tangle counts correlate well with the degree of cognitive impairment. These findings suggest the independent importance of tau abnormality in AD research which is involved in the neurofibrillary tangle formation. Recently, tau pathology without amyloid deposits and mutations in tau protein gene were reported to be the major pathogenic mechanism in Pick's disease, progressive supranuclear palsy, corticobasal degeneration and FTDP-17(frontotemporal dementia and parkinsonism linked with chromosome 17). These data suggest that understanding the causes and consequences of tau dysfunction might give new clinical and therapeutic solutions to many known tauopathies.

This study was conducted to improve the understanding of factors affecting an automobile seat cushion in dynamic conditions. When there are two dummies on the seat to measure each places respectively at once, the shape of the transfer function changes because the dummies affect each other as if they are linked with some kind of a spring when under excitation. A simple two-degree-of-freedom linear model is used to define a translational stiffness of dynamic coupling phenomenon. The cushion deflection model was created to find the relation between dynamic coupling and distance. Experimental set-up was made to compare with the two-degree-of-freedom linear model. The dynamic coupling factor could be utilized to improve the dynamic comfort of automobile seats.

This research program is directed at studying the behavior and the strength of reinforced concrete slabs sub¬jected to certain combination of punching shear and in-plane tension. Major variables to be investigated are the shear span to depth ratio of reinforced concrete slabs and the degree of the in-plane tensile force which is act¬ing tangent to the slabs. The experimental results are used for understanding of the degree of tbe interaction between the two loadings, and for developing a new practical design equation.

The Purpose of this study is to present basic data for the more reasonable and successful home management through understanding decision-making pattern that is the degree of their participation in the decision-making and their joint decision-making. Also, this study is the preliminary research for more scientific and wider studies on the Decision-Making and Marital Power Structure in Korea. This study make investigation into decision-making and marital power which is published on the Journal of Korean home Economics Association and the Journal of Korean Home Management Association and thesis for a degree form 1960's to 1987. As a result, the higher wife's age, education level are the more their participation, The increase of the wife's participation in the decision-Making can be regarded as the affirmative phenomenon in the decision-making can be regarded as the affirmative phenomenon that their status are raised in home management and joint decision are carried out. In 1970's, not only the generalization of the empirical studies have been increased but also the general theories(resource theory, exchange theory, system theory ) have been developed.

This study is carried out to examine the purpose of utilization and the degree of satisfaction on the information collected from the Internet site for the understanding of the reality of clothing information for college students. The results are as fellows; 1 . Three primary factors have been abstracted for the satisfaction of information. 2. The difference in the purpose of utilizing information, depending on the individual characteristic of students and the features related to computer, was shown in the difference of major and school year, number of the internet connection per day, capability of using computer, period of using computer, and frequency of information searching. The more the number of internet connection per day, the less the capability of using computer, and searching for information when required, internet can be utilized for study and work. 3. The difference in the degree of information satisfaction, depending on the individual characteristic of students and the features related to computer, was shown in the difference of major, school year, opportunity to take computer-related course, frequency of searching information, and etc. More positive and satisfactory response was derived from these not majoring in clothing rather than those majoring, those taking computer course related to clothing, and those searching for clothing information periodically. 4. The primary factors affecting the satisfaction on the overall information of clothing show difference in terms of sex and frequency of searching information. Female students show lower degree of satisfaction than male students and more satisfaction on the information searched as the frequency of searching becomes less.
