This study estimated a dual path model to predict consumers' intention to use a QR code virtual store by the effect of a mobile transaction system and a facilitating condition that also examined the role of experience and the use of an intention model in the context of a QR code virtual store. A longitudinal field study was conducted at selected QR code virtual stores. A questionnaire containing mobile transaction system, facilitating condition, performance expectancy, effort expectance, and intention to use was administered at two different points in time: Initial use (T1) and the second use after one month (T2). This study sampled 109 subjects who voluntarily participated in field studies twice at different time points (pooled sample=218). Participants were asked to visit at the QR code virtual store and undertake shopping tasks on their smartphones. The estimated dual path model showed that a mobile transaction system had a positive effect on performance expectancy, which influenced intention to use; however, facilitating condition had a positive effect on effort expectancy, but the effort expectance did not lead to intention to use. The effort expectance significantly also affected the performance expectance influencing intention to use QR code virtual stores. It was also found that use experience moderated the effect of mobile transaction systems on performance expectancy. The findings discussed a critical and success factor in consumer technology acceptance and use over time. A managerial implication was also discussed to capture potential users by emphasizing performance expectancy with the superiority of an innovative system or consumer facilitating condition as external resources in the introduction stage of new technology.

Purpose: The purpose of this study was to analyze students' expectance demand towards high school physical education teaching. Methords : 392 participants randomly selected from one girls' middle school and one girl's high school in each of five tracts and then selected two classes from each of the schools. They were asked to respond to a simple questionnaire about their views on the present physical education teaching. Results : Results showed that about one third of the participants would not choose physical education if the program were offered as an optional subject. Both male and female students ranked psychomotor domain as the top priority among the various learning objectives. Male students favored soccer and basketball while their counterparts liked badminton and volleyball. Over three-fourths of the participants suggested that students' opinions should be considered when teachers plan their program. Conclusion : The results of this study recommended that physical education teaching should be designed with considerations for professional values, societal changes as well as students' expectance on the design of physical education.

The purpose of this study is to examine the factors influencing usage intention of u-Healthcare with voluntariness in long-term care hospitals. This model tests various theoretical research hypotheses relating to u-Healthcare, UTAUT theory and voluntariness. The proposed model is analyzed to target long-term care hospitals. Questionnaires have been collected during two months of 2010 and total 142 has been considered to be valid. Smart PLS (partial least square) 2.0 and SPSS 15.0 have been utilized for deriving the study results. The results of hypothesis testing are as follows. First, performance expectance, effort expectancy and social influence positively influence usage intention. Second, facilitation not influence usage intention. Still due to lack of technical infrastructure to promote conditions of use u-Healthcare in long-care hospitals for u-Healthcare system also considered to be not significantly affected. Finally, performance expectance to usage intention for low voluntariness group is significantly larger than those for high voluntariness group. In addition, social influence to usage intention for high voluntarines group is significantly larger than those for low voluntariness group.

The purpose of this study was to compare consumer satisfaction by analyzing importance on characteristics of clothing, performance, and their inconsistency between Korea and the United States. The data was collected by using a survey based on three sages of pre-tests, and main survey conducted in The U.S and Korea. Data of 520 participants from each country (260 males and 260 females) was used. The results of this study is as follows: First, both consumers in Korea and U.S. showed five factors such as aesthetics/trend, body shape, practical use/wearing, care, and distorted. In performance factor of Korean students was consisted of wearing/care, aesthetics, body shape, distorted, and trend/symbolism while that of American students was consisted of wearing, aesthetics, body shape, trend/image factor, and distorted. Second, regarding importance rate, aesthetics/trend, practical use/wearing, care, and distorted affected satisfaction of Korean students whereas aesthetics/trend factor affected satisfaction of American students. Regarding performance, body shape factor, distorted, trend/symbolic affected satisfaction of Korean students whereas trend/image affected satisfaction of American students. Third, satisfaction of Korean and American students influenced re-purchase intention and positive word-of-mouth, so proved to be the result variable of satisfaction. By understanding the differences between consumers in Korea and U.S., apparel importers and exporters may develop effective business strategies to better fulfill their customers' needs and desires, and therefore, increase their profit.

Objective : Only a few studies have investigated the life expectance and health related quality of life (HRQOL) about stroke patients. The purpose of this study is to analyze the life expectancy, preference based quality of life(QOL) and quality adjusted life years(QALYs) of stroke patients. Methods : We used data of 10,533 adults from 4th Korean national health and nutritional examination survey 2009 for evaluating HRQOL of stroke patients. We also analyzed the life expectancy for stroke patients using life table from national public health data. Finally we calculated the QALYs with and without stroke conditions and assumed the difference of QALYs. Results : The mean age of stroke patients was assumed to be 65. Lower income and less educated groups were prone to be exposed to the stroke conditions. Common comorbidities of stroke patients were ischemic heart attack, hypertension, diabetes and hyperlipidemia. The proportions of participants who reported problems in each of the five EQ-5D dimensions increased significantly at chronic stroke group. Participants with chronic stroke conditions had an almost 6-fold higher risk of impaired health utility(the lowest quartile of EQ-5D utility score) compared with non stroke participants, after adjustment of age, gender, income, education, comorbidity variables. The differences of life expectancy and QALYs between non-stroke and stroke group from the age of 65 till death were assumed to be 0.767 year and 3.103 QALYs. Conclusions : Although the authors analyzed the affecting factors of QOL and assumed the differences of life expectance and QALYs about stroke patients using domestic national data and statistic references, well designed cohort studies should be needed to prove the causal effects of affecting factors and to assume more correct QALY differences.

In the shortest period of time, we achieved both industrialization and democratization. We also achieved good performance in health care sector. Whole population are covered by health insurance since 1989 and health outcomes, such as infant mortality, life expectance show good level. However, health care system has several problems, rapidly increasing rate of health care expenditure, dissatisfaction of both consumers and suppliers. Current health care system does not reconcile with market competition principle. Causes of these problems originated from 1977 paradigm which was formed to expand health insurance to whole population within short period. Dominant assumption of 1977 paradigm is to assure equitable access of health care by government's command and control. We urgently demand to reform the 1977 paradigm to suitable in 21th century. Our economy entered into a road to advancement. We have concerns how President Lee's administration reform health care system to harmonize with economic development and to achieve advancement in health care sector.

The purpose of this study is to analyze the relative importance of three factor -socioeconomic development, public health development, egalitarian nature of socioeconomic development- affecting mortality declines. Infant mortality rate and life expectancy at birth are used as the mortality index, that is the dependent variables, while GNP is used as the indicator of socioeconomic development, primary school enrollment ratio of female as the indicator of egalitarian nature of socioeconomic development, population per hospital bed as the indicator of public health. The data of these variables are collected two time-periods -before 1970 and during 1970-1980- over 50 countries. The explanatory data analysis is used as the statistical technique. We can find whether the relationship between dependent variable and independent variables are linear or nonlinear, and which case is the influential case in our model. The main results of this study are followings. First, the association between infant mortality rates and four indices are not linear. The most important factor explaining the variation of infant mortality is GNP, while primary enrollment of female is the second and GINI is the third important factor. However, population per hospital bed does not have a significant effect on the infant mortality rates in this study. Second, life expectancy at birth is log-linearly related to GNP. Unlike infant mortality rates, the most important factor explaining the variation of life expectance at birth is women's education and the next important factor GNP, and then the third one GINI. But, still population per hospital bed is not significantly related to the variation of life expectance in this study.

In this study, statistical analysis under both stationary and non-stationary climate was conducted for rainfall data measured in Seoul. Generalised Extreme Value (GEV) distribution and Gumbel distribution were used for the analysis. Rainfall changes under the non-stationary climate were estimated by applying time variable (t) to location parameter (${\xi}$). Rainfall depths calculated in non-stationary climate increased by 1.1 to 6.2mm and 1.0 to 4.6mm for the GEV distribution and gumbel distribution respectively from those stationary forms. Changes in annual maximum rainfall were estimated with rate of change in the location parameter (${\xi}1{\cdot}t$), and temporal changes of return period were predicted. This was also available for re-evaluating the current sewer design return period. Design criteria of sewer system was newly suggested considering life expectance of the system as well as temporal changes in the return period.
