This study analyzes the processes of change in oral health behaviors induced by oral health education for 23 university students. To this end, we analyzed the changing patterns of the stages of change and motivational components for each oral health behavior. Additionally, we performed an in-depth interview-based investigation of the factors influencing such motivational components. Oral health education was performed twice with a concrete purpose of changing the participants' behaviors in complying with the practice of proper brushing and flossing as the main oral health management, and checking the nutrient facts as a good dietary habit. Upon completion of these two sessions of oral health education, the level of change in oral health behavior was assessed by measuring the stages of change and motivational components for each oral health behavior. In order to gain an in-depth understanding of the reasons for the changes that were demonstrated more markedly during the second education session than during the first session, collective interview surveys were carried out after the second session. The contents of the recorded interviews were categorized into subscales of distinctive concepts on the basis of the items of a health behavior model. The study had the findings as below. First, after the first and second education sessions, some behaviors showed positive changes from lower to higher levels of practice. Second, self-efficacy about oral health behavior was high or perceived barriers were low when its necessity and benefits were clearly perceived. Third, educational features such as the practice and participation-centered education, and examining their own oral conditions influenced the participants' oral health awareness and behavioral changes. There is a need for oral health education capable of leading to practical behavioral changes by establishing concrete strategies of deriving various motivational components at each stage of the processes of change.

The purpose of this study is to secure the basic data for the physical environment of an eco-friendly restaurant by surveying and analyzing customer perceptions of the servicescape of an eco-friendly restaurant and to verify the organic causation of the servicescape of an eco-friendly restaurant and customer perceived value, attitude and behavior intention. The samples for empirical analysis were selected from the customers over 20 years who lives in Seoul and Kyung-gi suburbs have experienced visiting eco-friendly restaurant or green restaurant more than once a month. Total 300 copies of questionnaire were distributed for the survey from the second day to the fifteenth day of April for 14 days, and total 264 (88.0%) copies of survey questionnaire except for some questionnaires that had much strong lean tendency or the missing value was discovered. The research results are as follows; when a customer recognizes an eco-friendly restaurant favorably, he or she considers that servicescape plays an important role in deciding perceived value through tangible and intangible perceived values. Since, customer perceived value has a positive effect on attitude and behavior intention, the customer considers as affected on his/her behavior intention when satisfied with the eco-friendly restaurant, which is considered that positive customer attitude will have an effect on behavior intention. Thus, it is considered based on this in-depth analysis result that maintaining and providing servicescape of high standard in the manager's perspective will have a direct effect on ensuring tangible outcomes.

In this study, we developed a sustainability education program employing a project-based learning strategy for prospective teachers and investigated its effectiveness. A total of 23 senior students from a university of education participated in the study. The investigation involved a pretest on their pro-environmental behavior and attitudes, followed by a five-week implementation of the program, during which students individually engaged in energy-saving projects. Following the program, a post-test, which used the same questionnaire as the pretest, was administered. In addition, we conducted individual interviews with nine students who actively engaged in the projects. We analyzed the interview contents, portfolios, and reports; identified sub-concepts related to the program's effectiveness and its causes; and then organized them into subcategories. Then, we extracted recurring relationships among the subcategories to formulate a tentative explanatory model. The results indicate that the program positively impacted students' pro-environmental behavior and values/attitudes. Notably, the students' "sense of achievement gained through success" emerged as a significant factor influencing their pro-environmental behavior. Furthermore, some causes were found to indirectly affect pro-environmental behavior through pro-environmental values and attitudes.

Today, the development of new technologies due to the 4th industrial revolution requires work performance methods such as non-face-to-face collaboration. In response to this, various VR collaboration tools are emerging, but VR collaboration tools for brainstorming, which are used in collaboration or design development work, are not provided. Therefore, despite the advantages and possibilities of VR for non-face-to-face collaboration, there are limitations in practical use. Accordingly, the development of VR collaboration tools in a digitalized work environment is necessary, and research on UI design development for this is required. The purpose of this study is to propose a VR collaboration tool prototype by developing an interaction UI design that applies user hand behavior elements that appear during collaboration sessions through user research. This study was a qualitative study. The research method was to conduct user research through observation and in-depth interviews, and as a result of analyzing the data obtained from this, five types of user hand behavior elements were derived. In this study, an interaction UI design was developed that reflects hand gestures as behavioral elements. And using Unity and the Oculus Integration SDK Kit, we created a prototype VR collaboration tool that can be used without a controller. As a result of conducting a user evaluation of the prototype produced in this study, it was found that users had difficulty making hand gestures accurately, and it was possible to find areas for improvement in UI design. It is expected that this study will help develop interaction UI design for VR collaboration tools that can increase work efficiency.

The purpose of this study is to analyze the preference and value of consumers through the package design of cosmetics with the concept of cause branding, and to propose a package design that can satisfy consumers' needs. I have recruited an experimental group that emphasizes the importance of package design in purchasing cosmetics. And Survey and in-depth interviews were conducted by comparing cause brand's product with general brand's product. In the first experiment, the items were classified into cognitive, emotional, and behavioral responses and a total of 31 subjects were surveyed. In the second experiment, six interviewees were interviewed through a questionnaire prepared by extracting 4 items from Sheth 's consumption value standard. As a result of the experiment, consumers preferred a design that can quickly and accurately grasp the information of the product. Especially, it is not easy to know whether it is a cause brand's product. So It should be stated in the package how it will be socially beneficial.

The purpose of this study was to examine the image perceived by fathers of children with Internet addiction. To achieve the study purpose, we conducted depth interviews with ten fathers of children with Internet addiction who had been diagnosed as At-Risk through a face to face meeting. The reason for choosing face to face interviews was to listen to the subjective stories and descriptions from fathers about the kind of fathers they are, which are felt and experienced in real life. More specifically, we selected the depth-interview methods through structured questions and non-structured questions. The interviews were held for two or three hours through an individual meeting of ten fathers and data were collected in order to conduct a categorical analysis. The figures discovered from fathers of children were divided into four categories; the father figure who is indifferent to the Internet use of his child, the father figure depending only on education through the Internet, the father figure who is in a weaker point than the Internet and the father figure who is addicted to the Internet. Based on the study results, we suggested the desirable behaviors, which may be useful for both fathers and children with Internet addiction as well as a follow-up study.

The purpose of this study is to investigate communication efficacy of advertisement text through audience responses. This study approached qualitatively to KT&G TV commercials. The research proceeded as follows: First, as background theory, studies on audience focusing advertisement criticism and the interpretation of advertising texts were reviewed. Secondly, the characteristics of the audiences of the advertisements, analyzed through in-depth individual interviews as well as group interviews, were incorporated into a broad theme and then divided into different dimensions. Finally, the audiences' decoding code and critic reponses in reading ambiguous advertising texts, and the interrelationship between strategic ambiguity were discussed under a unified model. The major findings of this study are as follows: In interpreting the ambiguous advertising texts, the audiences use various decoding codes such as language, visuals, technology and rhetoric, and various critic responses such as linguistic, macroscopic, schematic, non-verbal and socio-cultural factors, in quite comprehensive manner. Also, it was shown that audiences make use of different decoding strategies in terms of their recognition, reliability, emotional attitude, and behavior. It can therefore be concluded that the strategic ambiguity has its limit in explaining its effectiveness in the entire dimensions of recognition, emotional attitude, and behavior, in the sense that the strategic ambiguity is most effective in recognition while it invokes more negativity in the behavioral dimension. Finally, this empirical study, focusing on qualitative analyses, may have its limit as well; however, deeper statistic-qualitative studies in the future could compensate for it.

Middle-aged women who have experienced the depression have been in pain for a long time. Depression in middle-aged women, which is rapidly increasing from their forties, has a problem that do not decrease in spite of various treatment methods. If the essential cause of depression in middle-aged women is due to the inability to detect the meaning of life because of the lack of the perception about the identity resulting from self-loss, a more qualitative research for a fundamental treatment method is required. The purpose of this study is to find out the essence and meaning of the experience of depression in middle-aged women and to help them to find their own selves through the process of individualization and to recover the whole health as well as to live as a self-transcendent being. Three Christian middle-aged women falling on critical and serious condition by BDI diagnosis were selected for the study. In-depth counseling and interviews were held from January to August 2018. In-depth counseling has provided detailed statements about the process of individualization of middle-aged women who have experienced depression, which applied 5 stages of Giorgi's Phenomenological Research Methodology. As a result, 261 semantic units and 11 sub-components were derived and structured by dividing them into two themes: depression experience and the process of individualization process, which are the subject group. This study has its significance in realizing essential meaning of pain by middle-aged women who experience depression and fundamentally preparing an opportunity to be cured through the process of individualization, as well as contributing for such middle-aged women to have abundant living by suggesting preventive measures to general middle-aged women who prepare for their old age.

The Multi-Object Goal Visual Navigation(MultiOn) is a visual navigation task in which an agent must visit to multiple object goals in an unknown indoor environment in a given order. Existing models for the MultiOn task suffer from the limitation that they cannot utilize an integrated view of multimodal context because use only a unimodal context map. To overcome this limitation, in this paper, we propose a novel deep neural network-based agent model for MultiOn task. The proposed model, MCFMO, uses a multimodal context map, containing visual appearance features, semantic features of environmental objects, and goal object features. Moreover, the proposed model effectively fuses these three heterogeneous features into a global multimodal context map by using a point-wise convolutional neural network module. Lastly, the proposed model adopts an auxiliary task learning module to predict the observation status, goal direction and the goal distance, which can guide to learn the navigational policy efficiently. Conducting various quantitative and qualitative experiments using the Habitat-Matterport3D simulation environment and scene dataset, we demonstrate the superiority of the proposed model.
