The purpose of this study is to investigate the current status of firefighting seatbelt use and factors affecting the wearing seatbelt of firefighters. The seatbelt use of citizens was also studied for comparative study. Two T-tests were conducted to confirm the characteristics of firefighters' safety belts wearing firefighters. As a result, there was a statistically significant difference, on seatbelt use in general vehicles, between firefighters and citizens. And a significant difference between fire vehicles and general vehicles, on firefighters' seatbelt use, and the average was lower in fire vehicles. Factor analysis, reliability analysis, correlation analysis and multiple regression analysis were conducted to 10 influential factors affecting seatbelt use of firefighters'. And factor analysis and reliability analysis revealed two major factors (Physical factors, Learning factors). In multiple regression analysis, it was confirmed the two independent factors had a positive effect on the dependent variable, the rate of seatbelt use of firefighters'.

Microblog is emerging as a new communication service because of its usefulness and real-time accessability. Recently, microblog services, such as twitter and me2day in Korea, are getting a great attention. Continuous use intention is critical to sustain the service. However, most recent studies are based on Technology Acceptance Model(TAM) and Expectation Confirmation Model(ECM). These models are only focused on individual factors and overlook social influence factors. Social influence has been indicated as a critical factor of technology adoption and diffusion in social context(Davis, 1989; Fulk et al., 1987). In this study, we explore factors related to social influence which effect on continuous use intention for 'me2day' that is one of the most famous microblog in Korea. The purpose of this study is to understand continuous use intention and examine the relationship among social influence factors, social presence, and continuous use intention. To understand the phenomenon of continuous use intention in microblog service, this study employed social influence theory and expanded it by adding personal network exposure and group norm as additional social influence factors. The results show that social identity, group norms, and social presence positively influences continuous use intention. Contrary to our expectation, personal network exposure does not influence on continuous use intention. Academically, this research can contribute to microblog research field through elucidating the relationship among social influence factors, social presence, and continuous use intention. Although there is not enough research which is considered social influence factors as major explanation for continuous use intention, this study can give novel point of view to understand continuous use intention of microblog. Practically, service providers could consider ways to encourage users to continually use microblog service by reinforcing social influence factors and social presence.

Many Koreans have been interested in health functional foods(HHFs). Use of health functional foods is growing rapidly. This study aims to identify the determinants of HFFs use focusing on health related factors. The subjects were 24,626 samples from Korea Health Panel in 2008. The subjects were divided into two group: under the 20 years old and 20 old and over. The logistic regression model was used to examine influence of health-related factors on use of HFFs for each group. About thirty percent of the subjects have used HFFs. The larger family size, higher education level of parents, more stable economic status and chronic diseases were positively related to use more HFFs in younger 20 years old. Higher education level, more stable economic status, chronic diseases were more likely to use HFFs in 20 years of age and over. Health related factors such as disability, chronic diseases, admission, and physician visit affect the use of HFFs in both groups. We confirmed that health related factors as well as socio-demographic and economic factors affect use of HFFs. In-depth knowledge about relationship between health related factors and HFFs is required.

Purpose: This secondary data analysis study was aimed at identifying the factors related to the patterns of alcohol use (normal alcohol use, hazardous alcohol use, and alcohol dependence) in the Korean adult. Methods: This study analyzed the cross-sectional data from 230,715 Korean adults aged 19 year and older who participated in the 2009 Korean Community Health Survey. Multinomial logistic regression was used to uncover associations between demographic, health related factors and the patterns of alcohol use. Results: The patterns of alcohol use was differentiated from the sociodemographic variables (residential area, gender, age, marital status, educational level, monthly income, and occupation) and with health related factors (smoking status, hours of sleep, body mass index, pain or discomfort, subjective health, stress level, liver disease, cardio/cerebro vascular disease, and depression). Hazardous alcohol use was lower in rural areas and lower among women, but higher among people who smoke, reported severe stress, and/or depression. Similarly, alcohol dependence was lower among women and among those in rural areas, and was more likely associated with those who smoke, have severe stress and depression. Conclusion: A number of factors are associated with patterns of drinking. Smoking, severe stress and depression seems to confound the problems of alcohol use. Additional research is needed to isolate those factors that are the most important influencing the use of alcohol.

In this paper, a research model was designed to investigate the factors influencing the intention to use of mobile easy payment services in China. Our research model includes the service factors(instant connectivity, economic and security), social factors(subjective norms and image), the user's individual factors(self-efficacy personal innovativeness and suitability), perceived ease of use, perceived usefulness and intention to use. A survey was conducted to collect the data with users who have had the actual using experience about mobile easy payment services. In this research, the data were collected by online survey, and in final analysis, 439 users' questionnaires were used. The empirical paper proves research hypothesis by using SPSS 22.0 and AMOS 23.0. The results of the study are as follows: the mobile easy payment service factors, social factors and the user's individual factors partially give positive effects to perceived ease of use and perceived usefulness; perceived ease of use gives positive effects to perceived usefulness. In addition, perceived ease of use and perceived usefulness have positive effects to on intention to use.

The subjects for this study on delinquent behavior, substance use and risk/protective factors consisted of 301 Korean-American students in grades 6 to 12. Findings were that (1) the delinquent behavior rate of adolescents using alcohol, tobacco or other substances was higher than that of non-using adolescents, increasing the odds of delinquent behavior from 3 to 45 times. (2) The probability of delinquents in the substance users group was higher by 7 to 44 times than in the non-users group. (3) The relationship with delinquent behavior of risk factors and substance use was much stronger than the relationship with delinquent behavior of protective factors and substance use. (4) The strongest predictor of delinquent behavior or substance use was the peer-individual domain.

The growth in the use of ubiquitous computing based on mobile services as an enabler to conduct business more effectively has been phenomenal. Technology acceptance model (TAM) has been applied in different contexts to examine a wide range of information technologies (IT). As more and more companies are finding ways to utilize ubiquitous computing based on mobile services, an important issue is to understand what factors will impact the decisions of consumers in adopting the services. Based on TAM with three additional groups of external factors, i.e., service-related factors (ubiquitous access, context awareness) and technology-related factors (perceived security risk, network connectivity) that are theoretically justified as having influence on both perceived usefulness and perceived ease of use which are additionally considered, a research model for the investigated technology acceptance was developed and empirically examined, using responses from more than intended users of ubiquitous computing based on mobile services. The specific purposes of this study are as follows. Firstly, this study is to identify service beliefs considering unique characteristics for ubiquitous services such as perceived ubiquitous access and perceived context awareness. Secondly, this study is to investigate network characteristics beliefs such as perceived security and perceived connectivity. Thirdly, this paper investigates the relationship among variables such as ubiquitous characteristics, network characteristics, behavioral beliefs, and intention to use ubiquitous web services. This study uses a structural equation model to test the research model. The major results of this study are as follows. Firstly, ubiquitous access has a influence on perceived usefulness and perceived ease of use. Context awareness has an influence on perceived usefulness. Secondly, User familiarity has an influence on perceived usefulness and perceived ease of use, and intention to use. User innovativeness has an influence on perceived ease of use. Thirdly, perceived security risk has an influence on perceived usefulness and perceived ease of use. Network connectivity has an influence on perceived usefulness and perceived ease of use. Fourth, there exist differential effects among factors in structural model among information, transaction, and entertainment services.

This study examined the childcare use pattern of the working mothers with preschool children and the factors affecting their use of multiple childcare. The 7th wave data of "Korea Welfare Panel Study" were analyzed for this study. The working mothers with preschool children were selected from the data set and a total of 292 working mothers were included in the analysis. More than 70% of the working mothers were using only one kind of childcare, mostly childcare center and kindergarten and 22.5% of the mothers were using more than two of childcare arrangements. Child factors, maternal factors, household factors, and economic factors were included in the hierarchical logistic regression model in the presented order to predict the use of multiple childcare. The results showed that the child's age and maternal education were positively related to the use of multiple childcare, while whether both parents live with the child, number of children within household, and the poverty status were negatively related to the use of it. Based on these results, we can confer that the main motive for multiple childcare use is to provide various experiences for their children.

This study aims to develop measures to turn former users and non-users of public libraries back into users by understanding the differences between the user, former user and non-user groups in terms of their perceptions to public libraries, as well as the differences between these groups in their perceptions regarding the factors to non-use of public libraries. A literature review and statistical analysis of the results from a questionnaire survey were conducted to identify the differences. The results from the statistical analysis showed significant differences between the user, former user and non-user groups in terms of their perceptions to public libraries and the non-use factors. From the results, we could categorize the factors into common non-use factors, non-use-only factors, and use interrupt factors, and we develop suggestions to improve the factors in order to move non-users and former users to frequent users of the public libraries.
