This study investigates the usage behavior and the perception of horticulturalists (horticultural activists) and simple users for urban community gardens. To this end, we surveyed 100 horticulturalists and 213 simple users. Questions in the survey are divided into five categories: 1) usage behavior of community gardens, 2) perception on the benefits of community gardens, 3) perception on the pros and cons of setting up community gardens, 4) willingness to pay for community gardens, 5) importance of specific benefits provided by community gardens. According to the survey, 95.0 percent of horticulturalists and 93.4 percent of simple users supported setting up community gardens. 58.0 percent of horticulturalists and 60.6 percent of simple users were willing to pay their residence tax for community gardens. And the annual membership fee plus resident tax of horticulturalists is 460,455 KW per person, which is 80.6 times more than willingness to pay of simple users. The results of this study can be used as basis data for valuing community gardens.

This study was to understand associated factors with frequent exposure to Internet pornography among Korean adolescents. We used data (N = 45,783) from the 2012 Korea Youth Risk Behavior Web-based Survey to examine demographics, family environmental variables, Internet use time, mental health indicators, sexual behavior, and delinquency among Korean adolescents identified as frequent users of Internet pornography. Multiple logistic regression analysis revealed that frequent users of Internet pornography were more likely to be older males with differences in living arrangements and perceived economic status of the family. They were heavy Internet users with mental health issues, such as a higher likelihood of sadness, suicidal ideation, suicide attempts, high stress, and a lower likelihood of feeling happiness. Their higher probability of exploratory (OR =1.79-4.60), and high-risk sexual behavior (OR = 2.20-7.46), and other delinquencies (OR = 1.74-7.68) requires more attention from public health professionals.

Purpose Wearable devices are widely used in our daily life. The purpose of this study is to investigate the relationship between persuasive designs of fitness trackers and users' physical activity behavior. Methods To test the research model, data was collected from a web-based survey in China, resulting in an effective sample of 166 usable questionnaires. The survey was restricted only to respondents who wear a fitness tracker. Results The sample surveyed in this study indicated that half of the respondents had been wearing a smart fitness tracker shorter than one year, and only 27% were long-time users (longer than two years). Dialogue support and social support strategies were both proved to be effective in increasing users' workout behavior intention. Social support strategies had a greater effect on behavior change than dialogue support strategies. Conclusion The findings from this study make several contributions to the practice. Wearable devices developers can employ the result from this study to help them design devices, which can persuade people to do more exercises and preserve a healthier life.

Purpose As the number of SNS users increases, the importance of SNS advertisement is also increasing. Thus, the purpose of this study is to analyze the effect of factors on effectiveness of SNS advertising, and expand research on users' attitude and behavior intention toward SNS advertising. Design/methodology/approach This study was designed to examine the structural relationships among SNS service attribute, users' cognitive characters, psychological factors, users' attitude and behavior intention toward SNS advertising. Concretely, SNS service attribute was presented as online interactivity, and users' cognitive characters were presented as perceived relevance and perceived intrusiveness. In addition, psychological factors were presented as presence experience and message credibility, users' attitude toward SNS advertising was presented as advertisement attitude and users' behavior intention was presented as WOM. Findings The results showed that online interactivity has a positive effect on presence experience and message credibility, but perceived intrusiveness has a negative effect on presence experience and message credibility. Perceived relevance has a positive effect on presence experience, but does not have significant effect on message credibility. Presence experience and message credibility have positive effects on advertisement attitude and WOM, and advertisement attitude also has a positive effect on WOM. Based on the results from this study, academic and practical implications can be drawn. First, the study extended the scope of research about SNS advertising through focusing on SNS service attribute and SNS users' cognitive characters and identified the relationship between presence experience, message credibility, advertisement attitude and WOM. Second, the results of this research can provide practical guidelines to develop effective advertising strategies for companies which promoting SNS as a marketing tool.

In-app advertisement is a fast-growing trend in mobile advertising, where user acceptance of ads is facilitated by the fact that users have voluntarily downloaded the app through which the ad is served. However, research in this ad category is limited. This study applies an extended version of the theory of planned behavior. Analysis results from 412 young mobile users in Vietnam using structural equation modeling showed that while localization and perceived enjoyment affected user intention to watch in-app ads as expected, perceived behavioral control and trust did not. Such results may be due to embedding the ads to applications, confusing users' behavioral intentions. The results underline the need for more future research in the area. In practical terms, companies should improve localization and entertainment aspects of ads to create more relevant and engaging advertisements.

The purpose of this explanatory study was to provide baseline information on the secondary prevention health behavior of cervical cancer in Korea which was related to the utilization of the Papanicolaou (Pap) smear screening test. The secondary data from the 1992 Korean Health Behavior Survey was used for analysis in order to determine sociodemographic profiles and the predictor variables. The sample analyzed for this study contained 1,489 Korean women residing in Korea aged 20-59 selected by multi-stage sampling method from the 1990 Korean census. Univariate, bivariate, and logistic regression analysis were performed to produce the findings of this study. Only 27.9% of the study sample had had a Pap test in 1992. It was found that the relative sociodemographic profiles of the Pap test between users and non-users were distinctive. The predictors variables were age, marital status, educational status, usual source of care, perceived household economic status, health check-up, and presence of chronic diseases

This study was designed to examine fast food consumption, nutritional knowledge, food behavior and dietary intake of university students and to investigate if there were differences in these variables by fast food consumption. The questionnaire was administered to university students in Daejeon. Data(n=269) was analyzed using $x^2$-test and analysis of variance. Subjects were mostly female(62%) and freshmen or sophomores(86%). Based on the frequency of fast food consumption, subjects were categorized into non-users(27.9%), users(<2 times/week, 42%) and frequent users($\geq$2 times/week, 30.1%). Those who used fast foods(n=194) consumed the foods 7.5 times per month, on the average. Subjects scored 15.6 out of 20 on a nutritional knowledge scale, showing the moderate level of knowledge. When examined by fast food use, the nutritional knowledge score was 15.5 for non-users, 16.1 for users, and 15.0 for frequent-users(p<0.05). Only two items, regarding 'fat type(animal, plant) and health' and 'importance of having breakfast', were significantly different by fast food consumption, with user group and non-users scoring higher than frequent-users(p<0.05). Food behaviors, measured by 20 items, were not desirable, with mean scores of 51.5(possible score: 20-100). Subjects showed problems in eating meals regularly, eating a variety of foods, eating breakfast, and consumption of some food groups(vegetables, fruits, and proteins). Fast food non-users showed more desirable food behaviors than users or frequent-users, such as having processed foods (p<0.001) and eating-out less frequently(p<0.01). Dietary intake data showed that some nutrient intakes, including energy, calcium, iron, zinc and folic acid were less than 75% of the RDA. Index of nutritional quality(INQ) was adequate except for calcium and zinc. Compared to non-users or user group, frequent-users of fast foods consumed higher amounts of lipids(p<0.05), and had lower INQ for calcium(p<0.01). This study described the status of fast food consumption, nutritional knowledge, food behavior of university students, and provided some baseline data for planning nutrition education for university students.

The study purpose was to investigate the factors related to fast food consumption of university students. Factors were identified using the Theory of Planned Behavior. Based on the pilot study, 18 behavioral beliefs, 7 normative beliefs and 19 control beliefs were identified. Data (n = 269) were analyzed using analysis of variance or $X^2$,/TEX> tests. Subjects were categorized into non-users (27.9%), users (42%) and frequent users ( $\geq$ 2 times/week, 30.1%). Regarding behavioral beliefs, users or frequent users responded more positively on advantages of eating fast foods including ‘taste’ (p < 0.001), ‘making me feel full’(p < 0.001), ‘diverse menus’(p < 0.05) than non-users. Compared to users, non-users responded more positively on the item that eating fast foods leads to eat vegetables less (p < 0.05), and negatively on ‘making me eat more salt’(p < 0.05). Most of the referent groups, parents (p < 0.001), sisters/brothers (p < 0.01), relatives (p < 0.01), friends (p < 0.05), boy/girl friends (p < 0.05) were important sources of influence regarding subjects' fast food consumption. Users or frequent users felt less control over factors or situations that make it consume fast foods (9 out of 19 control beliefs). These factors included; availability issues (p < 0.001), ‘not having other foods on hand’(p < 0.01), ‘others eating together like fast foods’, ‘convenience’, ‘social increase in fast food use’, ‘easy to get fast foods anytime’(p < 0.05). In addition, users of fast foods were more likely to eat fast foods when they don't have time, when they do not like to cook, when they feel hungry (p < 0.05). These results suggest that interventions for university students include strategies to moderate fast food use by modifying behavioral beliefs, suggesting alternative menus and behavior modification techniques, increasing perception of control, and eliciting social support.

With a rapid extension of functions in mobile phones, text input method has become very important for mobile phone users. Previous studies for text input methods were focused on Fitts' law, emphasizing expert's behaviors with one-handed text input method. However, it was observed that 97% of Korean mobile phone users input texts with two-hands. Therefore, this study was designed to develop a prediction model of two-handed Hangul text entry method including novice users as well as experts for mobile phone. For this study, Fitts' law was hypothesized to predict experts' movement time(MT) whereas Hick-Hyman law for visual search time was hypothesized to be added to MT for novices. The results showed that the prediction model was well fitted with the empirical data for both experts and novices with less than 3% error rates. In conclusion, this prediction model of two-handed Hangul text entry including novice users was proven to be a very effective model for modeling two-handed Hangul text input behavior for both experts.
