The purpose of this study was to examine the consumers' image and factors of wear comfort, expectation and satisfaction levels of wear comfort of hiking gear in order to investigate the consumer perception of wear comfort of hiking gear. The questionnaires were distributed to 400 people in their 40s and 50s and, 260 of which were used to data analysis. The questionnaires were comprised of questions about the image, factors, expectation and satisfaction levels of wear comfort of hiking gear, and demographic characteristics. Data were analyzed by frequency analysis, factor analysis, reliability analysis, correlation analysis, ANOVA, Duncan test, T-test with SPSS 19.0 IBM for Windows. In demographic characteristics, 43.5% of respondents were male and people under 45 years of age were at 17.7%, those between 46 and 50 with 46.5%, those between 51 and 55 with 28.9%, those between 56 and 60 with 6.9%. The results of this study are as follows. Responses of male and female consumers to image of wear comfort were similar and ten or more mentioned reponses by men were well-being and freedom from pain, stretchability, light weight, absorption of sweat, softness. Wear comfort of hiking gear was shown to include mobility/pressure factors, moisture factor, psychological factor, tactile/keeping body temperature factors. It was shown that the expectation and satisfaction levels of wear comfort of hiking gear were relatively high and were not influenced by consumer's sex and age, but were affected by the objective of mountaineering.

Objective: The objective of this study is to identify the risk factors for falls among the Korean elderly population. Methods: We analyzed the data on 167 persons of 65 years of age or older who have experienced falls drawn from the Third Korea National Health and Nutrition Examination Survey. We conducted a cross-tabulation analysis and logistic regression analysis of the impact of the socio-demographic characteristics, health-related behavior, mobility, and morbidity upon the frequencies of falls. Results: Among the socio-demographic characteristics, gender(p<0.001), marital status(p<0.1), and the type of medical insurance(<0.1) were found to be statistically significant, Among the constraints on mobility, the severity of walking problems, (p<0.001) and depression(p<0.05) proved to be significant, As for variables related to health-related behavior, the level of routine physical activities (p<0.001) was found significant, Finally, rheumatism(p<0.1), osteoporosis(p<0.05), diabetes(p<0.1), urinary incontinence(p<0.01) were also significant. A logistic regression analysis of the incidence of falls revealed that urinary incontinence was the most important risk factor with an odds ratio of 2.7. Conclusion: Although a variety of factors affect the frequencies of falls in the elderly population, urinary incontinence proved to be the single most important risk factor. This finding implies that education for fall prevention is crucial for those with urinary incontinence.

This study examines determinants of film consumption. Using structural equation modelling, this study explores some factors that explained film consumption based on film tastes and information seeking and socio-demographic factors. The major results are as follows: firstly, the major factor for explaining film consumption was individual tastes for films. The higher the degree of tastes for films, the greater the degree of film consumption. Secondly, there were significant relationships between tastes for films and film related information seeking such as internet search behavior and the use of film blogs. More specifically, the use of film blogs partially explained the degree of film consumption. Thirdly, a demographic factor like gender was highly correlated to film consumption. However, an income factor was not correlated to fim consumption. In conclusion, the degree of film consumption was determined by tastes for flims, the use of film blogs and gender factors.

Objective To determine the socio-demographic, psychologic, hematologic, or other relevant factors associated with hand grip strength in Korean farmers. Methods A total of 528 healthy Korean farmers were enrolled. Hand grip strength was measured in both hands using a hydraulic dynamometer. Socio-demographic characteristics were assessed and anthropometric measurements were obtained. Psycho-cognitive measurements such as sleep quality (Pittsburgh Sleep Quality Index) and Go/No-Go test response time were conducted. In addition to physical measurements, serologic parameters including insulin-like growth factor 1 were measured. The factors associated with hand grip strength were analyzed using multiple linear regression analysis after adjusting for age, height, and weight. Results The mean hand grip strength was associated with the Pittsburgh Sleep Quality Index total score (${\beta}=-0.12$, p=0.01), the Go/No-Go test response time (${\beta}=-0.18$, p=0.001), vitamin D (${\beta}=0.12$, p=0.02), and insulin-like growth factor 1 levels (${\beta}=0.1$, p=0.045). In female farmers, hand grip strength was only associated with the Pittsburgh Sleep Quality Index total score (${\beta}=-0.32$, p<0.001). Conclusion The results of this study demonstrate that hand grip strength was associated with sleep quality and attention in Korean farmers.

The purpose of this study is to find a way to increase the examination rate by presenting the current state of national health examination. To this end, demographic factors(Gender, age, income level, education level) and health factors(Smoking, alcohol, obesity, subjective health status) were selected, and whether the selected factors were different for each group, and the examinees according to the number of hospitals and income level were visualized. As a result, except for subjective health status in health factors, population factors, and number of hospitals were all related to the examination. In addition, among the age factors of the demographic factor, those in their twenties and those with a low income level and those who were underweight among the health factors of obesity had a high rate of non-testing. Therefore, it is considered necessary to promote, support, and educate those untested by these groups.

Purpose - The primary purpose of this study is to employ effective marketing methods using market segmentation of coffee shops by determining how motivations to visit coffee shops have different impacts on demographic profile of visitors and characteristics of coffee shop visits, so as to draw out a better understanding of customers of coffee market. Research design, data, and methodology - Data were collected using surveys of self-administered questionnaires toward coffee shop users in Daejeon, Korea. A number of samples used in data analysis were 253 excluding unusable responses. The data were analyzed through frequency, reliability, and factor analysis using SPSS 20.0. Factor analysis was conducted through the principal component analysis and varimax rotation method to derive factors of one or more eigen values. In addition, the cluster analysis, multivariate ANOVA, and cross-tab analysis were used for the market segmentation based on the types of motivation for coffee shop visits. The process of the cluster analysis is as follows. Four clusters were derived through hierarchical clustering, and k-means cluster analysis was then carried out using mean value of the four clusters as the initial seed value. Result - The factor analysis delineated four dimensions of motivation to visit coffee shops: ostentation motivation, hedonic motivation, esthetic motivation, utility motivation. The cluster analysis yielded four clusters: utility and esthetic seekers, hedonic seekers, utility seekers, ostentation seekers. In order to further specify the profile of four clusters, each cluster was cross tabulated with socio-demographics and characteristics of coffee shop visits. Four clusters are significantly different from each other by four types of motivations for coffee shop visits. Conclusions - This study has empirically examined the difference in demographic profile of visitors and characteristics of coffee shop visits by motivation to visit coffee shops. There are significant differences according to age, education background, marital status, occupation and monthly income. In addition, coffee shops use pattern characterization in frequency of visits to coffee shops, relationships with companion, purpose of visit, information sources, brand type, average expense per visit, important elements of selection attribute were significantly different depending on motivations for coffee shop visits.

The purpose of this study was to identify the effect of clothing involvement, store and brand loyalty orientation on the information search behavior. The study subjects comprised 298 females living in Seoul and Kyung-gi area. The data were analyzed with factor analysis, regression, cluster analysis, ANOVA and correlation analysis. Clothing involvement and information search behavior consisted of various factors. Clothing involvement, store and brand loyalty influenced information search behavior. Fashion and clothing involvement was the most important factor which influenced all loyalty and information search behavior(i.e. brand and store loyalty, personal and nonpersonal information search behavior). According to store and brand loyalty factors, female consumers classified into three groups : low loyalty, brand loyalty and store loyalty group. Three groups showed different clothing involvement, information search, clothing purchasing behavior and demographic variables. Therefore, loyalty orientation is the important factor which can describe the consumer behavior more effectively.

Finding influential factors from given clustering result is a typical data science problem. Genetic Algorithm based method is proposed to derive influential factors and its performance is compared with two conventional methods, Classification and Regression Tree (CART) and Chi-Squared Automatic Interaction Detection (CHAID), by using Dunn's index measure. To extract the influential factors of preference towards political parties in South Korea, the vote result of $18^{th}$ presidential election and 'Demographic', 'Health and Welfare', 'Economic' and 'Business' related data were used. Based on the analysis, reverse engineering was implemented. Implementation of reverse engineering based approach for influential factor analysis can provide new set of influential variables which can present new insight towards the data mining field.
