Objectives : The purpose of this study was to examine the relationship of oral health behavior factors to oral health promotion behavior in dental hygiene students and nonhealth-related majors, to identify factors affecting their oral health promotion behavior and ultimately to provide information on the oral health promotion of college students and behavioral factors related to that. Methods : The subjects in this study were three-year-course dental hygiene students and two-year-course nonhealth-related majors in G college located in the city of Gwangju. A self-administered survey was conducted for 11 days from September 9 to 19, 2009, and the answer sheets from 473 respondents were analyzed. To look for connections between their major and the characteristics of their oral health promotion behavior, t-test was utilized, and t-test and one-way ANOVA were carried out to find out the relationship oral health promotion behavior by general characteristics. Besides, multiple regression analysis was employed to grasp factors affecting oral health promotion behavior. Results : Among the subfactors of oral health promotion behavior, the dental hygiene students statistically significantly outdid the nonhealth-related majors in thorough post-meal toothbrushing(p<0.01), toothbrushing method(p<0.001), use of fluorine-containing dentifrice(p<0.001) and good nutrition(p<0.05). But the latter statistically significantly outperformed the former in use of fluorine-containing rinse(p<0.001) and limited sugar intake(0<0.05). Regarding variables affecting oral health promotion behavior, the age group, whether to get a dental checkup over the last year and whether to use oral hygiene supplies were identified as the variables to impact on oral health promotion behavior. Specifically, the age group(dental hygiene students) and the get a dental checkup over the last year(nonhealth-related majors) had a greater impact. Conclusions : To promote the oral health of college students, comprehensive oral health education should be provided, which covers the importance of dental checkup, recommendation for the use of oral hygiene supplies, etc. Specifically, oral health education should be offered as one of general education courses in order for nonhealth-related majors to get into sound life habits and improve their oral health promotion behavior. To make it happen, required institutional measures should be taken.

The period of data collection was from July to August, 2001. Research instrument was composed of 61 structured items 17 items related to demographics and sex, 44 items related to the need of sex education. Data were collected through the self-report method by the researcher and one trained assistant. The instrument developed by the researchers was employed to measure the need of sex education and it's Cronbach's $\alpha$ = 0.9349 in this research. Data were analyzed by frequency, percentage factor analysis and t-test using SPSS WIN Program. The findings of this study are summarized as follows : 1. The highest score among characteristics of sex was 'less interest about sex(42.6%)', 39.0% of subjects got information about sex from friends or elders. 52.3% of subjects consulted friends or elders about sex problems. The number of sex education lessons was 1-2 times in school during last semester (61.0%). Education by the school nurse was 35.9% to students. 43.1% of subjects announced moderate satisfaction on sex education. 2. The mean score of the need for sex education was $2.88{\pm}0.47$ (lowest value 1, highest 4). The most wanted sex education factor was 'chastity and sexual responsibility($3.33{\pm}0.67$)' and followed by 'family and marriage ($3.26{\pm}0.62$)' and 'considerations of sex($3.07{\pm}0.69$)'. Meanwhile, the lowest wanted sex education factor is 'physiological characteristics of male ($2.47{\pm}0.72$)', followed by 'sexual behavior ($2.49{\pm}0.75$)'. The most wanted sex education item was 'the meaning of family ($3.54{\pm}0.75$)' and followed by 'the cautions to prevention from sexual abuse ($3.49{\pm}0.78$)' and sexual activity and responsibility($3.43{\pm}0.77$)'. Meanwhile, the lowest wanted sex education item is 'masturbation ($2.16{\pm}0.97$)', followed by 'circumcision($2.32{\pm}0.97$)'. 3. There is no significant difference between boys and girls in mean score about the need for sex education(t=-.715, p=.476). Sex education factor that girl-students wanted was 'physiological characteristics of female'. Sex education factor that boy-students wanted was 'family and marriage'. Sex education items that girl-students wanted were 'cautions during menstruation', the relation of ovulation and pregnancy', caution to prevention from sexual abuse' and sexual behavior and responsibility'. Sex education items that boy-students wanted were 'the meaning of family', 'the importance of marriage', 'male's sex organs', 'a wet dream', 'the method to resolve sexual curiosity', 'sexual intercourse' and 'the connection with the other sex'. In conclusion, the mean score of the need for sex education is medium. The route to attain knowledge about sex and sexual problem is through consulting friends and elders. Therefore, it is necessary to give sex education that is suitable to the subject's needs and methods. Also, it is necessary to give differently strong point about sex education between female and male students.

After the rapidly changing business management environment and financial crisis, high prices and domestic recession in Korea posed threats to the business survival of small and medium enterprises (SMEs). This paper looks at the potential of micro business owners for sustainable development: those who have a spirit of entrepreneurship and the potential to be a hidden champion. Our study of micro business values uses structure equation modeling by LISREL. We have done so in order to understand the foundation of management innovation and success model of micro enterprise by increasing the entrepreneurship and management performance relationship analysis. A micro-enterprise is a type of small business, found only in Korea, often registered as having ten or fewer employees. We examine the successful type of hidden champions and the influence of entrepreneurship on start-ups in business. As compared to past research on the SME entrepreneurship, this study segments small businesses even further. Small business entrepreneurship was classified into three forms that are most appropriate for the Korean situation today: innovation, risk-taking, and pro-activeness. This research is meaningful as it is Korea's first empirical analysis on four business types: wholesale and retail sales, food and lodging business, service business, and manufacturing business. Thus far, research on small business entrepreneurship was carried out using small-scale investigative analysis. However, this research attempted to develop a model that can explain a cause-effect relation of the motivational level when it comes to the difference of entrepreneurship by each business type and small business start-up success factors. Various conceptual and operational definitions could be developed in a diverse and precise manner. Independent variables that are related to the success of small businesses can be developed additionally to examine the success factors related to the systematization in detailed manner. The research showed that the innovation, risk-taking and pro-activeness of the manifested difference in the degree of perception depending on the type of small businesses. Among the four business types, the ones that manifested the highest successful start-up rates were food, service, wholesale and retail sales and manufacturing. Results after conducting the regression analysis are shown on, which proves that the small business entrepreneurship exerts direct effect on the financial management performance of small businesses. In other words, small business entrepreneurship exerts a positive effect on the small business financial success and management performance. The R² value is 0.61. It is possible to know that the perception of systematization and variables on attitude explains the 61% of the success for small self-employed businesses management performance. We define start-up key factors that are helpful to achieve internal growth of firms by finding business survival strategies. The results also focus on Korean government policy for micro enterprise and small business support.

Large scale secular registry or surveillance systems have been accumulating vast data that allow mathematical modeling of cancer incidence and mortality rates. Most contemporary models in this regard use time series and APC (age-period-cohort) methods and focus primarily on predicting or analyzing cancer epidemiology with little attention being paid to implications for designing cancer registry, surveillance or evaluation initiatives. This research models age-specific cancer incidence rates using logistic growth equations and explores their performance under different scenarios of data completeness in the hope of deriving clues for reshaping relevant data collection. The study used China Cancer Registry Report 2012 as the data source. It employed 3-parameter logistic growth equations and modeled the age-specific incidence rates of all and the top 10 cancers presented in the registry report. The study performed 3 types of modeling, namely full age-span by fitting, multiple 5-year-segment fitting and single-segment fitting. Measurement of model performance adopted adjusted goodness of fit that combines sum of squred residuals and relative errors. Both model simulation and performance evalation utilized self-developed algorithms programed using C# languade and MS Visual Studio 2008. For models built upon full age-span data, predicted age-specific cancer incidence rates fitted very well with observed values for most (except cervical and breast) cancers with estimated goodness of fit (Rs) being over 0.96. When a given cancer is concerned, the R valuae of the logistic growth model derived using observed data from urban residents was greater than or at least equal to that of the same model built on data from rural people. For models based on multiple-5-year-segment data, the Rs remained fairly high (over 0.89) until 3-fourths of the data segments were excluded. For models using a fixed length single-segment of observed data, the older the age covered by the corresponding data segment, the higher the resulting Rs. Logistic growth models describe age-specific incidence rates perfectly for most cancers and may be used to inform data collection for purposes of monitoring and analyzing cancer epidemic. Helped by appropriate logistic growth equations, the work vomume of contemporary data collection, e.g., cancer registry and surveilance systems, may be reduced substantially.

Purpose - PB (Private Brand) refers to the product for which the distribution company plans the production independently, consigns the production to the manufacturer, or attaches the self-developed trademark and sells it. To reinforce competitiveness in such a market environment, diverse products development, systematic management activities, and marketing efforts to analyze and understand the consumers' behavior regarding PB products are emphasized. Therefore, this study aims to investigate the relationships among PB product attributes, consumption emotion, brand attitude, and brand loyalty in general supermarkets. First, PB product attributes were defined using the five categories of perceived price, store image, familiarity, perceived service, and perceived quality, based on preceding studies. This study examined the influence of PB product attributes on consumption. Further, this study examined the relation among consumption emotion, brand attitude, and brand loyalty. This study provides more detailed and concentrated strategic implications. Research design, data, and methodology - In this study, the research model was designed to examine the relation among PB product attributes, consumption emotion, brand attitude, and brand loyalty. For the data collection method, the questionnaire survey comprised multiple items for each component and the direct interview method was employed. To collect data, the questionnaire survey was conducted for customers who personally visited the general supermarket after verifying the PB product purchase experience. The questionnaire survey was performed for one month, May 2014. A total of 300 questionnaires were distributed and 240 questionnaires were used for the analysis, excluding the unanswered and insincere questionnaires. The data were analyzed using SPSS ver. 20.0. Results - First, PB product attributes had a significantly positive effect on consumption emotion. The PB product attributes perceived by the customer at the point of service contact are important to form the positive consumption emotion. Second, consumption emotion had a significantly positive effect on brand attitude. Third, the consumption emotion had a significantly positive effect on brand loyalty. Such consumption emotion is an important factor in causing the positive evaluation on the brand attitude perceived by the customer. Fourth, brand attitude had a significantly positive effect on brand loyalty. The consumption emotion was positively represented to invoke the relational continuance behavior. The relational continuance behavior accompanies the repetition of purchase, word of mouth, and recommendation activities, and influences trust regarding the brand, for which the customer maintains the transaction continuously. Conclusions - The PB product attributes perceived by the customer at the point of service contact are important factors to form the positive consumption emotion. Based on this result, the discount store service provider would prepare the measures that can make the customer recognize the positive value, and make more detailed efforts. Consumption emotion is an important factor to cause the positive evaluation on the brand attitude perceived by the customer. Based on this result, the general supermarket must make efforts to provide fun or convenience in the purchase process for consumers.
