The purpose of this study is to evaluate the combination of suit details through visual evaluation which helps compensating middle aged womens body defects for their more attractive fashion styles. In this study, styles of the evaluated suits are formal and classical. The designs of evaluated suits are manipulated in 40 different kinds by the essential elements such as collars, necklines(tailored collars, soutien collars, stand collars, round necklines, V-necklines), bottoms(slacks, skirts), pocket(flap pocket, none) and opening(opened, closed). The data evaluated by a multiple ranking test were analyzed by mean, paired t-test, ANOVA and Duncans multiple raged test. The results are summarized as follows: 1) The classic style suits-middle aged womans body construct looks better when she is wearing it with the combination of suit details; opened tailored collar jacket with flap pocket or non-pocket, opened stand collar jacket with non-pocket, closed soutien collar and round neckline jacket with non-pocket, closed V-neckline jacket with flap pocket or non-pocket on slacks. 2) The middle aged woman wearing slacks looks smaller in upper body, longer in lower part of her body and taller as a whole than when wearing a skirt suit. And Opened jacket makes a middle aged woman be seen with less appeared abdomen than that on closed jacket. The stand calar and round neckline jacket with non-flap pockets makes her look smaller in upper body and hip. 3) With tailored, soutien, stand collar jacket, it looks slimmer in a neck, narrower in shoulder, smaller in upper body, and taller than on a round neckline and V-neckline jacket.

Background and Objectives: The influence of music training on different areas of the brain has been extensively researched, but the underlying neurobehavioral mechanisms remain unknown. In the present study, the effects of training for more than three years in Carnatic music (an Indian form of music) on the discrimination ability of different areas of the brain were tested using P300 analysis at three electrode placement sites. Subjects and Methods: A total of 27 individuals, including 13 singers aged 16-30 years (mean±standard deviation, 23±3.2 years) and 14 non-singers aged 16-30 years (mean age, 24±2.9 years), participated in this study. The singers had 3-5 years of formal training experience in Carnatic music. Cortical activities in areas corresponding to attention, discrimination, and memory were tested using P300 analysis, and the tests were performed using the Intelligent Hearing System. Results: The mean P300 amplitude of the singers at the Fz electrode placement site (5.64±1.81) was significantly higher than that of the non-singers (3.85±1.60; t(25)=3.3, p<0.05). The amplitude at the Cz electrode placement site in singers (5.90±2.18) was significantly higher than that in non-singers (3.46±1.40; t(25)=3.3, p<0.05). The amplitude at the Pz electrode placement site in singers (4.94±1.89) was significantly higher than that in non-singers (3.57±1.50; t(25)=3.3, p<0.05). Among singers, the mean P300 amplitude was significantly higher in the Cz site than the other placement sites, and among non-singers, the mean P300 amplitude was significantly higher in the Fz site than the other placement sites, i.e., music training facilitated enhancement of the P300 amplitude at the Cz site. Conclusions: The findings of this study suggest that more than three years of training in Carnatic singing can enhance neural coding to discriminate subtle differences, leading to enhanced discrimination abilities of the brain, mainly in the generation site corresponding to Cz electrode placement.

The purpose of this study was to investigate the relationships between life style and clothing purchase intention and purchase criteria in internet shopping-mall of male and female consumers. The subjects were 275 internet users (male: 164, female: 111). The results of the study were as follows. Five factors of life style derived by factor analysis:'Digital Orientation','Economy Orientation','Positive Activity','Fun Orientation', and'Home Orientation'. The dress types to be based on the purchase intention in internet shopping-mall was classified into four dimensions by factor analysis: Casual Wears & Single Item Clothes','Formal Wears','Miscellaneous Goods', and'Underwears ＆ Night Clothes'. Internet users showed relatively high purchase intention in casual wears & single item clothes and miscellaneous goods. Clothing purchase intention in internet shopping correlated significantly with home orientation in males, and with digital orientation in females. Subjects high in fun orientation placed importance on design as clothing purchase criteria. Males high in positive activity placed importance on price, color, sewing, brand, and wearing appearance. Females high in digital orientation believed design, color, material, refundment condition, and fashionability were important as purchase criteria. The level of digital orientation of dress purchasers in internet shopping-mall was higher than that of non-purchasers in case of males, and that of fun orientation was higher than that of non-purchasers in case of females. The present findings suggest that life style such as digital orientation and home orientation appeared to be important in predicting the clothing purchase intention in internet shopping mall.

The purpose of this study was to analyze the effects of respite care. The analysis was conducted by reviewing published intervention studies on the effects of formal respite care for caregivers of dementia patients, patients with dementia, and the prevented or delayed rate of institutionalization of the patients. Method: Two computerized databases (MEDLINE, CINAHL) were searched to find respite care-related articles published from the year of 1981 to 2000. A total of 49 published articles were identified. Of them, nine studies, which met for the inclusion criteria of this study, were included. Results: Results revealed that there was little evidence of the effect of respite care on, not only caregivers' burden, stress, depression and well-being, but also the rate of institutionalization of the patients. It was noteworthy that dementia patients reported fewer problems in behavior, although cognitive functioning and activity of daily living abilities continued to decline. However, these findings should be carefully interpreted because of methodological problems, such as non-random sampling, non random group assignment, a small sample size, uncontrolled confounding variables, limited period of services, and no specific types of services. Conclusion: It is recommended to conduct intervention studies of respite care being conducted in Korea with the corrections of methodological problems suggested from this study.

The purpose of this study is to examine the concept and importance of the hidden curriculum, which has an influence on the learning, culture, and identity formation of medical students, and to examine the student culture related to the hidden curriculum. The hidden curriculum can be defined from various perspectives. However, these definitions commonly include the concept of the whole experience students gain from school life in implicit ways, even though the school does not intend it. The hidden curriculum is related to non-cognitive areas and the culture formation of students in various way, including positive and negative content, and is important since once this curriculum is formed, it has a long-term impact. Therefore, it is necessary to consider not only the formal curriculum but also the hidden curriculum in order to apprehend the overall educational outcome of medical school. For this purpose, schools need to not only support studies on the hidden curriculum but also to endeavor to provide faculty and staff with educational and administrative support so that they can understand the hidden curriculum and be equipped as a role model. Furthermore, medical students need to endeavor to form a positive student culture in order to establish an appropriate identity as a doctor in the future.

In this study digital human models of ship construction tasks using modeling & simulation were constructed and human models' activities through human activity analysis were evaluated. Human Factors experts analyzed the actual workers' tasks using the same technique used in human activity analysis at the same time. The main objective of this study is to check a possibility of applying digital human modeling technique to ship construction tasks that are mostly non-standardized(not uniformed) whereas most applications of digital human modeling technique have been applied to standardized tasks. We evaluated postures of both real workers and digital humans by RULA. It turned out that the final scores of RULA evaluation on real workers are the same as the RULA scores for digital humans. However, there were differences of RULA detail scores between real workers and digital humans in the several processes related with the wrist twist and deviations. Those differences are considered to be resulted from the error in the on-site measuring worker's body dimension which could be reduced by accurate tools to correct data for body dimension and digital real drawings for facilities. The results showed possibility of application of digital human modeling and ergonomic analysis on informal work operations as well as formal operations in the shipbuilding industry.

The study examined the socio-economic factors influencing the participation of rural farming households in barter trade in Ondo State, Nigeria. The objectives were to compare the socio-economic characteristics of the participants and non-participants in barter trade, analyze the preference for barter trade and identify the constraints to it. Also, the factors affecting respondents' participation in barter trade were identified. Empirical results indicated that there were significant differences in the socio-economic characteristics of the participants and non-participants in barter trade. The SWOT analysis showed that possession of agrarian attributes by the locality where the trade is practiced was the strongest factor ensuring the survival of barter in the study area. Double coincidence of wants was found to be the most prevailing weakness associated with barter while the major reason for participation by some households was that the quantity of commodities received is usually higher compared with cash transactions. Transportation cost to barter markets was found to be the greatest threat to the continued existence of barter trade in the area. The results of the Probit model showed that age, household size, transportation cost to cash markets, farm size, distance to barter markets, and formal education significantly affected the probability participating in barter trade.
