The purpose of this study was to examine the relationship between the dietary habits and oral health of elderly people in an attempt to pave the way for the development of oral health promotion programs geared toward improving the quality of life of the elderly. The subjects in this study were senior citizens who were selected by convenience sampling from Seoul. The findings of the study were as follows: 1. Regarding subjective oral health state, 54.5% of the elderly people, more than the half, considered their mouth to be in good health. The number of their mean remaining permanent teeth was 13.71. 47.5 percent of the senior citizens investigated had no shaking teeth. 2. Those who found themselves to be in good oral health had meals on a regular basis(p=0.022) and ate detergent food often. The gaps between them and the others was significant(p=0.005). In contrast, the elderly people who were in a bad oral health frequently ate cariogenic food(p=0.044). 3. The elderly people who had 21 teeth or more ate detergent food often(p=0.029), and those who owned no teeth had a sweet teeth(p=0.003), ate more cariogenic food(p=0.001) and had a snack frequently(p=0.026). 4. The subjective oral health status had a positive correlation to detergent food intake(r=0.23) and had a slightly negative correlation to preference for sweets(r=-0.14), cariogenic food intake(r=-0.14) and snack intake(r=-0.06). The number of tooth was positively correlated to detergent food intake(r=0.23) and negatively to preference for sweets(r=0.32), cariogenic food intake(r=-0.30) and snack intake(r=-0.21). The presence or absence of shaking teeth had a positive correlation to snack intake(r=0.14). The above-mentioned findings suggested that the dietary habits of the elderly people had a statistically significant relationship to subjective and objective oral health state, which indicated that there was a close relationship between oral health and dietary habits. Therefore how to improve dietary habits as well as oral health should be taken into account when oral health promotion programs are developed for the sake of the elderly. That would contribute to promoting the oral health of elderly people and eventually boosting their quality of life.

This study proposed the design development of performance uniform for Korean classical music. To do this, we considered the state of the performance uniform of the Korean Classical Music Band through photographic data. The research targeted the performers in Korean Classical Music Band, and conducted a survey for the preference of type, pattern, decoration, color and fabric materials. Based on the results, we extracted the design of performance uniform, which is suitable for the environment of Korean classical music performance and meets the substantial requirements of performers. The performance uniform that the current national or public Korean classical music bands are using, has two types: Western clothing and Hanbok. The attire is influenced by the genre of the music that they are playing because one of its main functions is to deliver the music to audience effectively. In addition, there are some differences in the uniform based on the gender, but no division in the design of clothing according to music instruments. However, the result of the survey show that there was no difference in preference by gender, but there was some difference according to the division of music instruments. On this study, we reflected this result in the design, and proposed the design of an convenient outer garment for everyone to wear in the music performance band.

This study determines whether certain cognitive biases (i.e., time preference, goal attainment expectation, unrealistic optimism, and overconfidence) and a specific negative mood-state (i.e., anxiety) influence credit misuse among college students. Data were collected from fourth-year college students (N=1,146), all of whom attended the same university in the southwest United States. Hierarchical multiple regression analyses and moderator analyses were employed to test the research hypotheses. Results showed that specific cognitive biases and anxiety were directly associated with credit misuse. We found that the longer goal attainment was delayed, the greater the students' unrealistic optimism concerning future income; in addition, the more overconfident they became with respect to financial knowledge, the more frequently they engaged in credit misuse. The study also showed that the higher a student's level of anxiety, the more often that students engaged in credit misuse. We also found that cognitive bias factors and anxiety interact to influence credit misuse. Anxiety interacted with time preference and unrealistic optimism such that present-oriented time preference was negatively related to credit misuse while optimism toward future income was positively related to credit misuse, but only for students with high anxiety levels. The findings of this study are discussed in the context of understanding and preventing irresponsible financial behavior among young adults.

由于生产的全球化以及国家之间的文化交流, 东方元素越来越吸引世界的眼球. 在时装界, 一个时装设计师的文化背景往往可以催生新颖的设计理念, 使他卓尔不群. 人们对于东方元素的喜爱, 给传统时装市场带来了巨大的商机, 并且把基于文化的业务拓展到全球时装市场. 然而, 包含韩国传统文化的国际品牌还有待开发. 为了发展有韩国特色的国际品牌, 韩国人首先要在国内服装市场上认同本国文化, 然后才能进军国外市场. 便服非常适合采纳韩国元素, 因为这种衣服有很多用途, 很容易被广泛接受和使用. 而且, 多用途便服和时尚内衣的市场需求越来越大. 尽管便服市场在快速发展, 但是对便服的专门研究尚不多见, 目前在对发展中的现代化传统服装、时尚产品和品牌的研究中, 并不包括对便服的研究. 因此, 本论文调查了韩国的便服市场, 研究了消费者对含有韩国传统时装设计特色的便服的评价. 分析了对于韩国传统时装设计元素有购买意向的先例之间的关系, 并且比较了不同生活群体的消费目标. 产品质量, 零售服务质量, 感受价值以及对拥有韩国传统设计元素的便服的喜好被作为购买意向的先决条件. 同时, 本文设计了一个结构方程模型, 用于探讨它们之间的关系以及它们对购买意图的影响. 产品质量和市场营销中的零售服务质量结合在一起, 成为影响人们对韩国特色便服的偏好和价值感知的因素. 而且, 偏好和价值感知对购买意向的影响可以用同一模型来检验. 通过网上调查系统由女性消费者完成了一共357份的自填式问卷, 并制定了一份调查样本人群的生活方式、对于产品和销售服务的标准、对于韩国特色便服的价值感知、偏好以及购买意向的调查问卷. 此外, 问卷还将调查便服的采购和使用行为, 以便检验韩国便服的市场地位. 并且使用描述性分析, 因素分析, 聚类分析来分析数据, 以及使用AMOS 7.0.来进行方差分析和建立结构方程模型. 对于韩国便服市场地位的调查结果显示, 在我们的样本人群中大多数消费者都购买了便服. 便服在目前被认为是在家里穿的衣服, 是消费者比较而言投入较低的衣服. 在调查中显示, 大多数消费者每年仅仅购买2到3次便服, 花费在10美元以下. 购买便服的消费者们的生活方式共有四类: 传统价值导向的生活方式, 品牌影响的生活方式, 追求休闲的生活方式以及健康导向的生活方式, 这四类共计有12个项目. 基于这些生活方式要素, 便服消费者们又可以分为两类: 安乐派和保守派. 文章估量了对含有韩国传统时尚设计元素的便服的购买行为各组成部分之间的关系, 产品质量和零售服务质量都会影响到购买便服的偏好和价值感知. 这个研究结论证明, 高质量的产品和零售服务会对便服形成积极的优先效应. 价值感知和对便服的偏好会对购买意图产生积极的影响. 这个结果表明, 对便服所含有的韩国传统时尚设计因素的强烈偏好和价值感知能增强购买意图. 在两种不同生活方式的群体(即安乐派和保守派)的模型比较中, 结果显示产品质量和零售服务质量对安乐派群体的偏好和感知价值都有积极影响. 然而, 对保守派来说, 只有零售服务质量对偏好和购买意图有积极的影响. 由于安乐派对购买意图显示出更重大的影响, 包含韩国传统时尚设计因素的便服品牌应该关注安乐派的这些特征. 然而, 保守派对包含韩国传统时尚设计因素的便服在偏好和购买意图的关系中显得更强. 因此对包含韩国传统时尚设计因素的便服品牌来说, 它应该把重点放在如何激发保守群体消费者对便服的积极偏爱上. 这些结果提供了关于韩国便服消费者生活方式的信息, 也对那些计划进入韩国便服市场的时尚品牌, 尤其是那些与现行研究样本相似的, 目标为女性消费者的时尚品牌提供了有用的信息. 这一研究也为便服品牌和那些打算创造含有韩国传统时尚因素的高价值品牌提供了策略和市场洞察力. 考虑到不同生活方式群体的类型和便服或传统时尚商品之间的关系, 品牌设计者和市场策划人员可以运用这一研究成果作为市场定位, 目标设定, 以及市场销售策略的一个参考.

A health index was proposed that evaluates personal health state from both measured physiological variables and survey questions. Four health indices were defined such as cardiovascular index, stress index, obesity index, and management index. The total health index was calculated by summing these four health indices. Physiological variables such as blood pressure, heart rate variability(HRV), accelerated photoplethysmograph(APG), and body fat percentage were non-invasively measured and a survey questionnaire that asks personal health state, exercise intensity, and food preference was developed. The suggested health index was applied to thirty eight persons including 30 patients and 8 normal persons with an average age of 51.8. The average health index was estimated to be 75.1 out of 100 points. Young age group(below 50) and men group showed higher health indices than the aged(over 50) and women groups. The correlation coefficient between the cardiovascular index and stress index was found to be 0.513, which means stress is related to cardiovascular health state. The correlation coefficient between the measurements and survey questions was 0.385 for the cardiovascular index. It was as low as 0.182 for the stress index. More case studies may improve correlations between measurements and survey questions, and then, the current health index system may develop as an effective tool to evaluate personal health state.

In mobile computing research area, it is highly desirable to understand the characteristics of user movement so that the user friendly location aware services could be rendered effectively. Location based social networks (LBSNs) have flourished recently and are of great potential for movement behavior exploration and datadriven application design. While there have been some efforts on user check-in movement behavior in LBSNs, they lack comprehensive analysis of social influence on them. To this end, the social-spatial influence and social-temporal influence are analyzed synthetically in this paper based on the related information exposed in LBSNs. The check-in movement behaviors of users are found to be affected by their social friendships both from spatial and temporal dimensions. Furthermore, a probabilistic model of user mobile behavior is proposed, incorporating the comprehensive social influence model with extent personal preference model. The experimental results validate that our proposed model can improve prediction accuracy compared to the state-of-the-art social historical model considering temporal information (SHM+T), which mainly studies the temporal cyclic patterns and uses them to model user mobility, while being with affordable complexity.
