It is well known that soy isoflavones play beneficial roles in the prevention of chronic diseases such as breast cancer, cardiovascular disease and osteoporosis. However current data are not sufficient for estimating the level of isoflavone intake. To use the urinary isoflavone excretion as a maker of isoflavone intake,26 participants consumed the isoflavone extract capsule (90 mg soy isoplavones/capsule) daily for 3 months. The study compared effects of pre- and post-isoflavone supplement in the following parameters; physical examination, dietary recalls, and urinary isoflavon excretion. The average age, height and weight were 65.7 years, 149.4 cm, and 57.3 kg. Subjects maintained regular diet pattern, and average daily nutrient intakes between pre- and post- supplementation were not significantly different except vitamin A, carotene and vitamin C. There was no significant difference between pre- and post- supplementation in terms of daily isoflavone intake. The basal urinary isoflavone excretion was 8.37 mg/day (daidzein 6.23 mu genistein 2.14 mg), and average daily excretion rate was IS.8%. Urinary isoflavone excretion was significantly increased, after isoflavone supplementation for 3 months as compared the basal level (p<0.01). Our data suggest that urinary isoflavone level, especially daidzein and genistein, may be a useful maker to estimate isoflavone intake.

The deviation from put-call parity condition may affect market prices since it provides an opportunity of arbitrage to many participants. This study uses the KOSPI200 index data and examines the interdependence among spot, futures, and options contracts by examining whether the deviations from the parity have significant roles in price formation. Whenever the parity condition is violated, the deviation tends to affect the prices significantly in most markets. The results show that positive values of deviation are associated with the fall of the prices in the spot and put option contracts and the rise of the call option premiums, thus decreasing the deviations. Also, the decreasing impact of deviations lasts for at Beast an hour in most markets. Futures prices, however, do not show clear relations with the deviations, which suggests the possibility that futures markets lead other markets.

Objectives : In this study, the dental treatment satisfaction degree of the patients, who experienced the sleep dental treatment or non-sleep dental treatment, the revisit rate and the differences among the encouraging intention were compared and analyzed, and the primary factors through which the satisfaction degree of sleep dental treatment has influence on the revisits and the encouraging intention were analyzed, and the proposal was made on clinic management to raise qualitative medical service level on the basis of this study. Methods : The questionnaires filled out by the 202 users of a certain dental clinic located in Pohang-si, Gyeongbuk were analyzed. The frequency analysis and the crosstabulation analysis of the general characteristics of survey participants were carried out, and the satisfaction difference between the sleep dental treatment and the non-sleep dental treatment was identified with the t-test analysis. The multiple regression analysis were carried out to identify the factors through which the sleep dental treatment has influence on the through which the satisfaction degree of sleep dental treatment has influence on the satisfaction degree of the medical service and the revisited dentists. Results : In the medical service satisfaction degree in general, the sleep dental treatment had the higher meaningful value than the non-sleep dental treatment(p<0.05). In the case of the difference in satisfaction degree on each medical service factor, the satisfaction of the sleep treatment group was high in every case, but the meaningful difference showed up in the factors of waiting time, treatment procedure, revisit and the encouraging intention(p<0.01). The revisit to the sleep treatment dental clinic and the recommending dentist increased in proportion to the satisfaction degree of sleep dental treatment, and the Beta value appeared to be 0.337 at the influence of the subordinate variable(p<0.001). As for the influence on the sleep dental treatment satisfaction, the Beta value of the dental hygienist was the highest, marking the value at 0.375(p<0.01). As for the satisfaction of the patients who experienced the sleep dental treatment, the Beta value of the treatment fee was the highest, marking 0.352(p<0.001), in the multiple regression analysis of the revisit and the encouraging intention, and the 0.156 of dentist factor and the 0.152 of treatment procedure and waiting time showed lower regression coefficient(p<0.05). Conclusions : It is assumed that the satisfaction degree of sleep dental treatment, which is carried out as a new dental service has influence on the increase of revisit to the dental clinic as an important factor. But it was disclosed that the high level of treatment fee has the biggest influence on choice of revisit to the dental clinic. In the current medical charge system, the sleep dental treatment appeared to have a big influence on raising the quality of dentists, the satisfaction of patients, the revisit and encouraging intention, and also the roles of the dental hygienist was important. It is assumed that these facts are functioning as the factors that are linked to the increase of revisit and the encouraging intention.

This study attends to the effects of political entertainment as a newly emerging television genre on citizens' political talk. Particularly, this study suggests audience involvement and political information efficacy as key psychological factors that mediate the relationship between political entertainment and political discussion. More specifically, audience involvement was deemed as a conclusive concept that consists of such sub-dimensions as audience identification and parasocial interaction with program characters and transportation into the messages. Among 317 participants in an online survey, a total of 273 subjects, who had at least some viewing experience with political entertainment TV programs, were included in the final analysis. According to the findings, softer programs that piggyback political information on top of their entertainment content were more likely to increase viewers' identification and transportation. The viewer experience of identification further heightened the level of political information efficacy, which in turn positively contributed to one's willingness to participate in political talk and to hear the other side. It also appeared that political information efficacy significantly mediated the relationship between political entertainment viewing and political talk.

The aim of this study was to examine whether health promoting behavior was dependent on perceived health status and health attitude in adults, and whether health concern mediated the relationships among these variables. Structural equation modeling was applied to test a model in which perceived health status and health attitude were considered as exogenous variables while health concern as a mediating variable. The participants were 292 adults aged from 20 to 59 and completed the self-report measures. The results of the structural equation model showed that perceived health status and health attitude were positively associated with health concern and health promoting behavior. Health concern mediated the relationships between perceived health status and health promoting behavior, and also health attitude and health promoting behavior. The findings suggest that enhancing health attitude may play important roles to promote health promoting behavior in adults, and the development of various health education for adults in schools, work place, and health and medical organization might promote positive health attitude and health concern. Health education program in connection with preventive health examination also might contribute to activate health promoting behavior.

This study analyzes the processes and the needs of public library services for multicultural populations based on cooperation between public libraries and local organizations. In-depth interviews with public librarians and officers of local organizations were conducted for this case study. Result shows that cooperation was inevitable because there was not enough library personnel compared to the amount of services they have to provide, and the librarians did not have proper skills to serve the diverse populations. Public libraries were cooperating with many local organizations including the Multicultural Family Support Center. Gatekeepers of ethnic communities were playing important roles in promoting and inviting participants for library programs. Many children and young adults with immigration background gained positive views on reading and libraries after participating library programs based on cooperation between public libraries and local organizations, which was recognized as the best achievement of cooperation by many interviewees. Despite many good results of cooperation, how to get to the majority of diverse populations who are not library users yet is still a question mark. Interviewees for this study all agreed that current library service has limitations and insisted a whole new method to invite immigrants and their families to public libraries should be created.

As the Korean society ages, the number of women who specialize in community health care is expected to increase. Therefore, the purpose of this study is to identify and structure the nature of suffering due to job stress among female community health care professionals, and to provide basic data supporting the performance of female health care professionals. To use Parse's theory of human becoming, nine female health care professionals were selected in the community. After forming the "you and me" relationship, the researcher recorded the participants' distress through honest conversations. It was converted to the structure of human becoming through the extraction-synthesis and discovery interpretation process. Through conceptual interpretation, the structure of the experience was developed. At the results, the female health care professionals were the process of overcoming difficulty due to poor working conditions and conflict in roles between work and family through their skills and communication reinforcements in hopes for change. The stable national welfare policies must be established to sustain jobs with female community health care experts through improved working conditions.

The gender difference in social roles affects digital devices' utilization differences in man and woman even in the 21st Century. Prior studies analyze the digital divide (genders, ages, etc.) from the assessment perspectives of digital equipment, such as PCs. In the area of high speed internet, most functions of PCs have been replaced with smartphones, and around 80% of the mobile phone users adopt smartphones. Subsequently the inequality of physical access to the digital devices is no longer a criterion for digital divide. The focus on digital divide should be shifted from the physical access to other factors, such as socio-technical or socio-cultural ones. This paper examines utilization of women's digital equipment, in particular, preparing for tourism activities, which is popular but sensitive to the technology. A survey was conducted with participants of [Suncheon Garden Expo] 2013. The results of this study capture the inactive use of digital devices particularly women over 50s. This phenomenon (high utilization of the digital devices for social or informative purposes, but low utilization of the digital payment) implies other aspects of Korean women (economic independence, low self-assertion, technical difficulties, etc.), which is considered from the socio-technological convergence perspective. This study also has a practical implication on the side of the digital device developers as well as marketing, where the qualitative communication is likely to be incorporated for the women over 50s.

If we, as educators, want to put students at the center of learning in science classroom, we must let students express their voices and exercise authority. To do this, we developed a classroom activity about 'Making a pet poster', and then we explored how elementary school students perceived their roles and expressed their authority during this activity. Fourth grade students from an elementary school in the city of Seoul participated in the activity, which was videotaped and recorded. We found that students expressed their epistemic authority differently in small group activities and in whole group discussions. In small group activities, they desired to show their authority as "pet experts" by using and selecting various resources from their everyday lives and transforming those resources into suitable forms in public spaces. Meanwhile, in whole group discussions, participants were classified as either presenters or audience members to verify their authority in regard to the pet poster activity; presenters desired to achieve recognition as "pet experts," and audience members assessed the presenters as "testers." In addition, they expressed authority as teachers by leading the whole group discussions. Based on these findings, this paper suggests the implications for new educational strategies to foster a student-centered learning environment.

The public housing needs maintenance administration for improvement and retainment of residential condition by means of tenants participation. However, most researchers have considered tenants as passive participants in this context. The previous studies did not comprehend perspective of tenants participation and just measured the management preference and the level of satisfaction on maintenance. This study investigates the attitudes and perceptions of tenants on participation in public housing maintenance by introduced Q method that provides a systematic and rigorous quantitative means for examining human subjectivity. The subjectivity is classified as types according to cost and benefit factors by principal components analysis and varimax rotation of the extracted factors. As a result, this study present 5 types of tenants participation and expect to discuss desirable roles of tenant and org anization in public housing maintenance.
