This study was carried out by practical method in a subjectivity study accessible in-depth, in sloughing off old habit of functional quantity analysis about policy of dental treatment. The perception pattern come out in this study were divided into four types in Q-methodology. The result is as follows ; it is divided into 1[(N=11) : Extension Policy Type], 2[(N=13) : Institutional Improvement Type], 3[(N=5) : Image Improvement Type], 4[(N=14) : Treatment Focus Type], 5[(N=5) : Efficient Access Type], 6[(N=10) : Developmental Demand Type]. There are four types of fire fighter images. In conclusion, this study is to ascertain acceptance behavior about Reception Type on policy of dental treatment ; to offer a developmental suggestion about it.

Objectives: The administrative employees of government were analyzed on their levels of fatigue symptoms to reveal the various factors related to them. Methods: The self-administered questionnaires were performed, during the period between Dec. 5th, 2005 and Jan. 31st, 2006, to 1,005 individuals in the service of general administration located in Daejeon Metropolitan City. The survey items included subjects' socio-demographic and job-related characteristics, health-related behavior, degree of job demand, job autonomy, social support in work, type A behavior pattern, locus of control, sense of self-esteem, and degree of fatigue. The study results were analyzed and the authors came to the following major findings, by univariate and multiple regression analysis with degree of fatigue dependent variables and other variables independent. Results and Conclusions: The study results indicated that the level of fatigue symptoms is so complicatedly influenced by variable factors as well as job-related characteristics such as socio-demographic characteristics, rank in work, or job career, to a greater extent, by job specifications and personality traits(type A) like whether performing health-related behavior or not, job demand, job autonomy, social support in work, or sense of self-esteem. Thus the effective strategy for stress reduction among governmental employees requires additional programs focusing on innovated job specifications and managed personality trait.

A typical wear pattern was reported to resemble the fatigue crack growth behavior considering its mechanism, especially for amorphous rubbers such as styrene-butadiene rubber (SBR). In this study, the wear and crack growth rates were correlated using two separate experiments for carbon black and silica-reinforced selected rubber compounds. The wear rate was determined using a blade-type abrasion tester, where the frictional energy input during wearing was measured. The crack propagation rate was determined under different tearing energy inputs using a home-made fatigue tester, with a pure-shear test specimen containing pre-cracks. The rates of abrasion and crack propagation were plotted on a log-log scale as a function of frictional and tearing energies, respectively. Reasonable agreement was observed, indicating that the major mechanism of the abrasion pattern involved repeated crack propagation.

The wear behavior of styrene-butadiene rubber (SBR) and butadiene rubber (BR) was investigated using a blade-type abrader with a steel blade (SB), Ti-coated tungsten carbide blade (TiB), or zirconia blade (ZB). The wear rate of SBR against SB and TiB decreased with increasing number of revolutions because of the blunting of the blades during wear. However, the wear rate of SBR against ZB remained nearly constant with little blade blunting. Generally, the wear rate of BR was largely unaffected by the blade material used for abrasion. The wear rate and frictional coefficient of SBR were found to be higher than those of BR at similar levels of frictional energy input. A power-law relationship was found between the wear rate and frictional energy input during abrasion. A well-known Schallamach pattern was observed for SBR, while a much finer pattern was observed for BR. The blade material affects the wear rate of the rubbers because the macromolecular free radicals and blade tend to undergo mechano-chemical reactions. The inorganic ZB was found to be the most inert for such a mechanism.

This work was researched by practical method in a subjectivity study accessible in-depth, in sloughing off old habit of functional quantity analysis about reception type on movie-viewing perception. The perception pattern come out in this study were divided into four types in Q-methodology. The result is as follows ; it is that divided '1[(N=18): Personal-decision Type], 2[(N=14): Media Dependence Type], 3[(N=10): Self-leading Type], 4[(N=3): Positive Preference Type]'. Like this, it found that is very different type all over. Hereafter, this study is to ascertain acceptance behavior about reception type on movie-viewing perception, 21th ; to offer a developmental suggestion about it.

The purpose of this research is to investigate the relationship between personal traits and information behavior theoretically. Personal traits are often represented by "major type of personality found in an ethnic group or society" and measured by both degrees of affection and dependency in this study. In turn, information behavior is used to include unique features in information needs, information seeking, information source preference, and information searching pattern in library and internet. The data was collected through a survey with 162 college freshmen, and analyzed for both frequency test and Chi-square test. The major research result shows that dependency rather than affection has a statistically meaningful relation with information behavior, in particular, information needs and source preference. Also made are several methodological suggestions for further research.
