A blog is a personal website where its owner publishes his/her articles for others. A blog can have relationships with other blogs. In this paper, we define a network that is composed of blogs connected together with such relationships as a blog network. Blog networks can have two different propensities characterized by the articles published in the blogs: information-valued propensity and friendship-valued propensity. The degree of each propensity of a blog network plays an important role in deciding business policies for blog networks. In this paper, we address the problem of determining the degrees of two propensities of a given blog network. First, we determine the degree of the propensity of every relationship, a basic unit of a blog network, by using classification that is one of data mining functionalities. Then, by utilizing the result thus obtained, we compute the degrees of two propensities of the whole blog network. Also, we propose a method to solve the problem that the degree of propensities depends on the size of blog networks. To verify the superiority of the proposed approach, we perform extensive experiments using a huge volume of real-world blog data. The results show that our approach provides high accuracy of around 93% in determining the degrees of both propensities of relationships between arbitrary two blogs. We also verify the applicability of the proposed approach by showing that if determines the degrees of the information-valued and friendship-valued propensities correctly in real-world blog networks.

This study aims to identify the effect for exercise intensity on hypertension using propensity score based on the sixth Korea National Health and Nutrition Examination Survey data and to provide an evidence for the most effective exercise intensity for prevention or treatment of hypertension. Specifically, we select 3,486 subjects who aged between 18 and 65 years after excluding some subjects who are expected to have limited athletic ability. We estimate propensity scores for exercise intensity based on the confounders such as sex, age, smoking, drinking, and natrium intake. Considering the complex survey design, we conduct a descriptive analysis and multiple logistic regression for hypertension with propensity score as a covariate. Although the results of the study did not show statistically significant relationship between exercise intensity and hypertension, we expect that it can be used as a basis evidence that the appropriate exercise of moderate intensity may be more effective for the prevention and treatment of hypertension rather than strong intensity exercise and non-exercise.
This study was conducted by empirically analyzing the relation between effects of positive emotional response of female customers, who have at some point consumed food at Korean restaurants in Busan, and behavioral intention according to their food service consumption propensity. In order to achieve the objective of the study, the questionnaire survey was performed from March $10^{th}$ to $25^{th}$, and frequency analysis, confirmatory factor analysis, reliability analysis, correlation analysis, and SEM (structure equation model) were conducted by using SPSS 18.0 and AMOS for 248 questionnaires. As a result of an exploratory factor analysis, five factors were confirmed. In a confirmatory factor analysis, the average variance extracted (AVE) and composite reliability (CR) were confirmed as .508 to .665 and .905 to .946 respectively, which proved the convergent validity. In a hypothesis test, Hypothesis 1 was determined that the food service consumption propensity positively effects on emotional response. The results were as follows: the taste driven (${\beta}$=.325, t=3.907, p<.001), the health driven (${\beta}$=.190, t=2.688, p<.001), and the atmosphere driven (${\beta}$=.188, t=2.515, p<.001). Therefore, Hypothesis 1 was selected. Hypothesis 1 has determined that positive emotional response beneficially affects behavioral intention. As a result of an analysis, the standardized path coefficient was (${\beta}$=.496, t=6.388, p<.001), so Hypothesis 1 was selected. This result suggests that the taste driven factor has the biggest influence on emotional response in the food service consumption propensity for female customers, and food service business operators should strive to make a good restaurant atmosphere for customers to get positive emotional response (pleasure, comfort, satisfaction, and joy).
The purpose of this study was to verify potential differences in group- specific external feature concerns and beauty care behaviors of Korean women in their 20's~40's depending on their narcissistic propensity. This study is to take psychological approaches to narcissistic propensity of our contemporary society, so that it can get better understanding about consumers and provide marketing data on beauty-related industry. To meet the above goals, total 400 sheets of questionnaire were distributed to subjects from March 30 to April 8, 2009. Out of 376 sheets of questionnaire collected, total 355 valid questionnaires except incomplete 21 ones were used for final data analysis. For data analysis, this study used SPSS 12.0 as statistic program to perform factor analysis, reliability test (Cronbac's ${\alpha}$ coefficient), cluster analysis, t-test, analysis of variance (ANOVA), Duncan's multiple range test and multiple regression analysis. As a result, this study could come to the following findings: First, according to cluster analysis depending upon different factors such as self-directed narcissism, others-conscious narcissism and others-sensitive narcissism, it was found that our women in 20's to 40's could fall into 4 groups, i.e. complex narcissism group, mixed narcissism group, others-sensitive narcissism group and dispirited narcissism group. Second, according to analysis on potential differences in external feature concerns among four groups depending on their narcissistic propensity, it was found that there were significant differences in all relevant factors among groups. Third, according to analysis on differences in beauty care behaviors among four groups depending upon their narcissistic propensity, it was found that there were significant differences in all relevant factors among groups. Fourth, according to analysis on potential factors of external feature concerns that may influence beauty care behaviors of complex narcissism group, it was found that those factors had significant effects on fashion-orientedness, cosmetic surgery and personality pursuit of this group. And it was also found that there were significant differences in fashion-orientedness, cosmetic surgery, makeup and hair styling of mixed narcissism group, others-sensitive narcissism group and dispirited narcissism group respectively.
Thus purpose of this study is to examine the structural relationship among the LOHAS image of hotel restaurants, customer well-being menu preference, emotional responses, customer satisfaction, and customer loyalty. To test the hypotheses, a survey was conducted of luxury hotel customers in Busan and Seoul. Of the 400 questionnaires distributed 341 was used final analysis. For the hypotheses testing, frequency analysis, reliability and validity analyses SPSS was used while AMOS was employed to examine the relationship among the measured concepts. The results of testing are shown as follows: LOHAS image of hotel restaurants does have a positive effect on well-being propensity, as well as on customer emotional responses. The cooking function factor of well-being propensity results in a negative emotional responses, while the attractiveness factor of well-being propensity brings about a positive emotional responses. Emotional responses positively affect customer satisfaction, which then positively influences customer loyalty. The arising concept of LOHAS in the service industry can help to develop new menu items for LOHAS or well-being oriented customers. In particular, well-being menu propensity and emotional responses may become more important considerations in marketing strategy formation. This thesis provides a theoretical background of LOHAS image, well-being menu propensity, and emotional responses.
Expected consumer's consumption propensity affected by advertisement using media facade and how this advertisement can affect consumer response and advertising effectiveness will be examined practically. This research showed TV advertisement and media facade advertisement to each participants of research in order to evaluate consumer response and effectiveness of media facade advertisement and took a survey. Research result, positive response was observed that consumer who were exposed of media facade advertisement showed more positive cognition/emotional response than TV advertisement. And effectiveness of media facade is more than standard. However, product attitude was not statistically positive. Therefore, it can be said that media facade advertisement does not affect positively on product attitude, but it is effective on purchase intention. Next, consumer who is exposed of media facade advertisement showed little low correlation on cognition response and product attitude, but showed positive correlation on cognition response, purchase intention, emotional response and product attitude. Accordingly, more positive consumer's cognition and emotional response is, the higher advertisement effect can be observed. Last, positive result were not presented in consumer's consumption propensity in regards to rational/emotional response. This means that it is invalid to state that consumer response differs for consumer propensity. Through result of experiment, a statement that media facade is a new media that has various possibility as advertisement mediator had been proved. Especially, as it shows that positive effect exists regardless of consumer's consumption propensity, use of media facade as marketing means is reasonable for firm in order to increase satisfaction of consumer and brand value.
This study examined the effects of cosmetic selection attributes on consumers' purchase propensity and recommend intention. In addition, the moderating effect according to the consumer's deal proneness was verified. Finally, a multi-group analysis was conducted to verify the difference in the research model path according to the information source. Through this study, the selection attributes of consumers who purchase cosmetics were clarified. This study aims to meet the needs and demands of the related industry for more detailed and effective strategic insights by clarifying the structure of the influence of these selection attributes on purchase intention and recommendation intention according to the discount purchase intention. In order to achieve the research objectives due to this necessity, a questionnaire of 258 Korean female consumers was collected and used for research. The analysis results showed that product selection attributes, purchase intention, and recommendation intention all had a positive influence. As a result of analyzing the moderation effect according to the consumer's Deal Proneness, the results showed a moderating effect between the selection attribute and the purchase propensity, the selection attribute and the recommend intention, and the purchase propensity and the recommend intention. Finally, it was partially adopted as a result of conducting a multi-group analysis to verify whether individual paths of the model differ according to information sources.

The purpose of this study is to develop a board game design activity for environmental education and to investigate how it affects high school students' environmental knowledge, environmental literacy, and creative engineering problem solving propensity. Twenty-five freshman and sophomore students belonging to the environmental club participated in this study. The board game activity was designed as 10 class hours lessons based on the engineering design process. The main data source of this study was pre-post students' conceptual maps of the environmental topics (global warming or ecosystem destruction) to measure the background knowledge on the topic. In addition, the environmental literacy measurement questionnaire and the creative engineering problem solving propensity questionnaire were collected before and after the activity. The result shows that the number of environment-related words described by the students on the post-concept map increased compared to the pre-concept map. In addition, the environmental literacy score and the creative engineering problem-solving propensity score increased significantly after performing the board game design activity. The results show that environmental lessons using board game design activities can help student develop various competencies in a good way. As above, research that combines board games and secondary education must be activated, and a new educational method and systemic support for in-service teachers who want to apply it to science classroom is required.
Background: Dental hygienists emphasize the ethics of healthcare workers. To effectively cope with various ethical conflicts, it is necessary to establish a reasonable ethical value system. Therefore, this study intends to use basic data to develop ethics education programs and ethical value evaluation tools. Methods: We conducted a questionnaire survey targeting dental hygienists between January 1 and 15, 2023. A total of 251 people's responses were analyzed with SPSS Win 25.0, to perform frequency, t-test, one-way ANOVA, and multiple regression analysis. Results: The idealistic propensity (3.82 points) was higher than the relativistic propensity (3.42 points), and the absolutists showed a deontological position in the partnership area and dental hygiene work relationship area(P < 0.001). Regression analysis of factors affecting ethical values revealed that idealism (β=,444, p=0.000), marital status (β=-0.123, P = 0.035), and position (β=-0.154, P = 0.009) were significantly related to ethical propensity. Conclusion: It is necessary to develop an ethics education program that considers the ethical propensity of dental hygienists and establish firm ethical values by implementing situation-oriented ethics education that can respond to many changes and conflicts.
