Data from the 2001 Korea Health and Nutrition Examination Survey, a nationally representative, cross-sectional survey, were analyzed to assess prevalence of health intended food use overall and in relation to socio-demographic and lifestyle characteristics. Health intended food were classified into four broadly defined categories: vitamin and mineral supplements, health aid food, animal protein based restorative food and medicinal plants. Thirty three percent of adults aged 20 years or older reported taking health intended food in the past year : twenty four percent took vitamin or mineral supplements and medicinal plants were taken by 17 % of adults, health aid food by 15% and animal protein based restorative food by 6%. In multivariate logistic regression, female gender, older age, more education, regular exercise and non smoking were associated with greater use of vitamin or mineral supplements. Dietary quality was significantly associated with use of vitamin or mineral supplements or health aid food but not with use of medicinal plants or animal protein based restorative foods. Obese persons were less likely to take vitamin or mineral supplements. These findings suggest that epidemiologic studies of diet, demographic or lifestyle and health take health intended food use into account because of high prevalence of use of the food by the population and differential use of the food by socio-demographic and lifestyle characteristics.

The purpose of this study was to categorize dietary lifestyles and analyze intake behavior regarding beverages according to lifestyles of 276 university students in Yeungnam region. Frequency analysis, factor analysis, cluster analysis, reliability analysis, one-way analysis of variance, and ${\chi}^2$ tests were conducted using SPSS V.21.0. In the factor analysis, dietary lifestyles were categorized into one of five factors: health-seeking type, popularity-seeking type, safety-seeking type, economy-seeking type and convenience-seeking type. According to cluster analysis, respondents were divided into four groups: convenience-seeking group, wellbeing-seeking group, popularity-seeking group, and indifference group. Chi-square tests showed that there were significant differences in gender, grade, dwelling status, and monthly allowance according to the four dietary lifestyle groups. The level of dietary habits and percentage of correct answers related to beverages of the wellbeing-seeking group were highest among the four groups. The frequency of beverage intake was significantly different for carbonated drinks, milk and dairy products, and sport drinks according to dietary lifestyle groups. In addition, for beverage preference, there were significant differences in carbonated drinks, sport drinks, tea and functional drinks according to dietary lifestyle groups.

The objective of the study is to understand the characteristics of modernistic spatial design and, based on the understanding, to interpret fashion in terms of its spatial relationship with society, culture and human body, thereby looking into unique spatial characteristics fashion has. The main results of this study include : First, the rational space emphasizes geometric symmetry and harmony among each of design elements and is expressed by pursuing a perfect formative beauty that indicates an eternal formal beauty of a physical space. In addition, functional beauty is also pursued, making clothing convenient for activities. Second, the abstract space is characterized as a kind of purity by emphasizing simple patterns and colors and materials of purity for clothing, and it is sometimes expressed as being extremely abstract so that human body can be shown to be distorted. Third, for the uniform and neutral space, mass-production and production at home was made possible with clothing of simple patterns and of standard. In addition, it showed a tendency to become blurred in gender distinction for clothing with women wearing men's clothing, or borrowing design elements from men's clothing. Forth, the space as means of domination and control was shown to be segmented based on place, function and purpose. In addition, control on physical beauty was shown by promoting slim figures that are suited for lineal silhouette of clothing and circumstantial restriction on clothing occurred during war, serving to limit the styles of and purchase of clothing.

The main focus of this study is to understand realities of postmodern consumer culture by deconstructing fashion advertisements, Calvin Klein's ck One and cK be. The metaphysics of critical theory, visual and textual analysis are used to deconstructing the ads applying one of the postmodern cultural critics, Baudrillard' s notion of hyperreality. Through deconstructing the ads five postmodern characteristics representing hyperreality were found. First, there is no message regarding functional characteristics of the product offered in the ad, which is far from the modernist's utilitarian Point of view. Hyperreality in Postmodern consumer culture is consumption centered and focuses on the product's symbolic meanings. Second, especially for cK be, the ad uses atypicai, irrelevant models and images, which are introduced as a concept of ‘real people’ rather than the ideal person or body type. Third, there are transformations of the meanings from cK one to cK be such as the notions of globalization and gender which clearly represent ongoing reality in the Postmodern culture. Fourth, there are hidden meaning of hedonism and relativism, which are prevalent in postmodern ideology. Finally, models' bodies are used to convey messages as well as form the ground and figure in the ad that is a significant characteristic of postmodern consumer culture. In conclusion, the study of Calvin Klein's fashion ads supports the notion that advertising mirrors reality in postmodern consumer culture, which is hyperreality.

This study examined the various functions of public libraries, as well as user satisfaction and needs. We targeted 6 public libraries in the Seoul and Gyunggi area. After 280 library users were surveyed, the collected data were analyzed with an SPSS for Win 14.0 statistics program, where we used frequency, percentage, mean, T-test, One-way ANOVA, and Duncan's test. The major findings were as follows: 1) Half of the users used educational functional space, mainly in the 10-20 age group, who used it for educational purposes as a student or to prepare for getting a job. 2) There were gaps between the furniture arrangement and user preference since most libraries used a rigid system while users preferred a more flexible arrangement. 3) Space by space, public library satisfaction levels differed according to the users' gender and age. Satisfaction of the digital information room scored high, especially for users in their forties. Since public library users are diverse and require various functions, library interiors should be planned accordingly in terms of furniture arrangement and interior design. In particular, there was a gap between satisfaction by age groups, so libraries must account for community needs by considering the age group demographics of their surrounding areas.

It has been thought that males tend to use their brain hemispheres more laterally than females. However, recent fMRI studies have shown that there may be no difference in brain lateralization between genders. Functional near-infrared spectroscopy (fNIRS) presents a unique opportunity to acquire real time measurements of blood oxygenation changes to observe neural activity specific to the brain's left and right hemispheres. Using an in-house built multichannel fNIRS system, brain lateralization was observed from seven males and four females according to specially designed tasks for left and right hemisphere activation. The Pearson correlation coefficient and a modified Lateralization Index metric for continuous wave fNIRS systems were calculated to quantify brain lateralization. The preliminary results point to no significant difference in lateral hemodynamic changes between the genders. However, the correlation of symmetrical channel pairs decreased as the experiments progressed. To further develop this study, the subject's performance and the removal of global interference must be implemented for an improved study of brain lateralization.

For 299 patients who had undergone cataract surgeries we investigated the difference in visual acuity and refractive power before and after cataract surgery and the clinical change of the visual acuity and the refractive power according to age, gender, hospital visit time and specific medical history. We found the factors affecting preoperative and postoperative outcomes of the cataract patients in metropolitan hospitals by input, process, and outcome and analyzed medical characteristics and patient characteristics as the input variables. T-test and ANOVA have been performed for statistical analysis of functional status, and general status and the technical characteristic as the process variable and the outcome variable of diagnosis. Visual acuity improved significantly in patients who had undergone cataract surgery. However, the change in refractive power did not show a statistically significant difference but only a slight difference. The improvement of male patients was greater than that of female patients. The difference in age was more effective in patients under 50 years old and the effect of cataract surgery was relatively high in patients without the presence of specific medical history. Cataract surgery did not seem to help all of the patients, but it is more effective in improving visual acuity and refractive power. We conclude that simultaneous cataract surgery in both eyes is reasonable in order to have at least the better effect.

In the past few decades, great progress has been made on understanding the interaction between nutrition and health status. But despite this wealth of knowledge, health problems related to nutrition continue to increase. This leads us to postulate that the continuing trend may result from a lack of consideration for intra-individual biological variation on dietary responses. Precision nutrition utilizes personal information such as age, gender, lifestyle, diet intake, environmental exposure, genetic variants, microbiome, and epigenetics to provide better dietary advices and interventions. Recent technological advances in the artificial intelligence, big data analytics, cloud computing, and machine learning, have made it possible to process data on a scale and in ways that were previously impossible. A big data platform is built by collecting numerous parameters such as meal features, medical metadata, lifestyle variation, genome diversity and microbiome composition. Sophisticated techniques based on machine learning algorithm can be used to integrate and interpret multiple factors and provide dietary guidance at a personalized or stratified level. The development of a suitable machine learning algorithm would make it possible to suggest a personalized diet or functional food based on analysis of intra-individual metabolic variation. This novel precision nutrition might become one of the most exciting and promising approaches of improving health conditions, especially in the context of non-communicable disease prevention.

Previous research has empirically demonstrated the negative effects of social media use on young people's psychological well-being. Unlike most previous studies that focused on either Facebook or Instagram, this study comparatively examined the differences in upward comparison and its effects on self-esteem, life satisfaction, and depression between Facebook and Instagram. An analysis of survey data from 641 Korean college students, who reportedly use these two social media more actively than any other age group, found that college students experience more upward comparisons on Instagram than on Facebook. Upward comparisons on both Facebook and Instagram increased by college students' age and weekly usage time. Upward comparisons on Instagram increased by the additional factors of gender (females more than males) and number of "followings." Subsequently, the effects of upward comparison on psychological well-being were found to differ by social media platform. Upward comparisons were found to negatively impact all determinants of psychological well-being only on Instagram, but not on Facebook. The differences in upward comparison and its impact on young users' psychological well-being found in this study were discussed in terms of the different functional characteristics of the two social media platforms, which provides direction for further research needed to establish guidelines for healthy social media use by young people.
