The purpose of this study was to develop a nutrition education website for children, especially those around the 4th-6th grade levels. Among the already existing websites providing nutritional information for children, 7 websites with comparable amounts of information were evaluated in terms of their topics, credibility, content, ease of use, and aesthetics. In addition, a survey was conducted to assess the need for nutrition information among 305 elementary students. The food pyramid was the topic offered most often on those websites. Information on nutrients, digestion, food safety, nutrition labeling, and healthy eating habits were available on the websites. Some of those websites also provided games or quizzes to attract the children's interest. However, seine of the websites did not give any information on the person responsible for providing the information, which is most important in determining the credibility of the website. Other problems were that some information was too difficult for children, and some of the websites did not provide a way to search for information. According to the survey results, the topics that children wanted to know about were‘desirable weight’,‘cooking’,‘correct food choice’,‘weight control method’,‘calories consumed during exercise’, but, they did not have a high interest in‘asking questions’‘books with nutrition messages’,‘under weight’,‘negative effect of weight control’and‘helping hungry children’. Based on these results, we developed a new nutrition education web-site, ifood’(http: //1 ifood.or.kr). We focused on helping children develop healthy eating habits by providing information which is easy and practical for children. However, we neither included the program to assess their dietary intake, nor provided entertaining background sounds, which children like. Also, the game section is composed mainly of quizzes. Therefore, we need to further develop exciting games to teach nutrition to children. In the near future, the newly developed website should be evaluated by children regarding understandability and coverage of the contents as well as usability and design, and then revised to improve the educational effect.

Purpose - The Millennial Generation, which grew in the wake of the spread of the Internet and rapid changes in the media environment, is rapidly moving from the traditional broadcasting environment to the Internet-broadcasting environment in terms of content acceptance. With the emergence of UGC (User-generated content), the change in the status of single-person content creators enables the growth of multi-channel networks (MCN), a new content-distribution platform and an agency concept for single creators. Youtube-based MCN produces multiple single star producers and casts and provides its own video series through Youtube. It is also emerging as a major M&A target for global media providers in terms of providing content to a wide range of consumers with the same interests and consumption characteristics. In addition, for the Millennials generation, which are part of their lives, MCN is becoming the most suitable media for TGIF (Twitter, Google, i-phone, Facebook). Accordingly, this study defines newly emerging MCNs and analyzes the factors for accepting MCN-produced content based on the push-pull-mooring (PPM) model. Research design, data, and methodology - An empirical analysis is performed through a questionnaire survey. For this purpose, 204 people who have experience of watching MCN were studied. Collected data is processed through analysis of a structural equation model using R to test the hypothesis. Results - For the MCN service to become an alternative to existing media, it is necessary to continuously promote cultural diversity and diversity of attempts that conventional media cannot provide. It is the attractiveness of the alternative that has the greatest influence on the intention to switch to a MCN service. When we look at MCN content so far, certain patterns such as game progress, introduction, food, and chat rooms have already appeared. We need to overcome this and develop a completely new conceptual content that we have never seen before. This requires a more generous viewer perception of the topics covered. For diversity, linguistic and verbal violence should be tolerant in common sense to provide a foundation for securing cultural diversity. Conclusions - In this study, we tried to develop a comprehensive approach to the substitution effect of MCN. In terms of academic achievement, the PPM model is used to enhance the utilization of media and broadcasting. Practical implications are to provide an analytical framework for verifying alternative or complementary effects when viewers switch to MCN.

이 논문은 전통적인 전설이 현대에 어떻게 변화하고 존재하면서 전설로서의 가치와 의미를 계승 발전시켜 나가고 있는가 하는 것을 확인해보려는 의도에서 시작되었다. 연구 대상은 현대의 전설 중 학교괴담과 나란히 가치가 있다고 판단되는 군대괴담을 대상으로 하였다. 군대괴담은 인터넷을 중심으로 전승이 활발한 현대 도시전설로서 '군대에서의 초자연적이고 기이한 경험을 소재로 하되 공포감을 불러일으키는 서사적 이야기'라고 정의할 수 있다. 커뮤니티 외에도 유머 사이트, 게임사이트에서 활발히 전승되고 있으며, 최근에는 괴담 전문 사이트까지 등장하였다. 이처럼 이런 다양한 사이트들에서 활발한 전승을 보이고 있는 군대괴담은 '귀신 체험형', '불고기 GP형', '괴무전형'의 세 가지 유형으로 나눌 수 있었다. 가장 많은 각편을 보유하고 있으며 내용도 풍부하고 다양한 '귀신 체험형'은 귀신에 대한 전통적 관념에서 크게 벗어나지 않는다. 이름에서부터 엽기적 공포감을 불러일으키는 '불고기 GP형'은 실제 사건과 관련을 가지며 공포감을 더욱 고조시키고 있고, '괴무전형'은 영화나 드라마에서 낭만적으로 많이 활용된 소재임에도 군대괴담에서는 공포스럽게 인식되고 있다는 점에서 차이를 보인다. 군대괴담은 제목과 내용에서부터 그 이야기가 실제로 경험한 것이라는 점을 지속적으로 강조하면서 구체적인 근거들을 제시하고 있다. 진실성의 강조는 공포심을 현실화하려는 의도이며 이는 안전에 대한 욕망에서 기인하는 것이다. 이처럼 군대괴담은 공포에 초점을 맞추면서 이야기 속 사건 자체의 역사성과 진실성을 밝히려는 노력을 하게 되고 그러면서 현실의 역사, 현실적 상황이 처한 진실, 현실적 이념은 소거되는 한계를 노정하고 있다. 전통적인 전설이 지녔던 역사성과 진실성이 군대괴담의 경우에는 다른 방식으로 변주되고 있는 것이다.

Rapid development of information technology has generated a new industry and market. In particular, network technology such as the Internet and other computer networks made transaction activities switched from traditional offline commerce to e-commerce. Among them, digital content is bit-based object which is created and distributed through electronic environment. In particular, many entertainment contents such as the music, the movies, and the computer game softwares are main products. Although digital content commerce has high potential demand, it lacks the consideration about the factor related to maintaining existing customer such as customer loyalty and switching costs. There has been a number of research on customer loyalty and other factors affecting it in the traditional electronic commerce environment, but there is a lack of research which examines the characteristics of digital content. The study about the effect of switching costs on customer loyalty in digital content commerce is necessary because the customers of digital content commerce market are from those of other e-commerce market or traditional offline commerce market. In addition, customer loyalty and switching costs are important factors because they may build up greater customer retention. For that reason, this study focused on examining the relationships among switching costs, antecedents for switching costs, and customer loyalty in online digital music service industry. The study has three major purposes: (1) to find antecedents of switching costs on digital content commerce and examine effect of antecedents for switching costs; (2) to identify effect of switching costs on customer loyalty in digital content commerce and examine moderating effects of alternative attractiveness; (3) to identify the differences of antecedents for switching costs by contents transmission type(streaming service and downloading service). And, the online digital music service industry is selected in this study since there are many users and transactions incurring. To accomplish these purposes, a survey questionnaire was developed and distributed to 256 informants. Survey instrument was developed based on previous research and pre-established survey items. Total of 206 surveys are collected and used in the data analysis. Among the respondents, 56.8% is male and 43.2% is female. Also, 86 responses were streaming service user group and 120 responses were download service user group. These data was analyzed using regression analysis. Major findings of empirical analysis can be summarized as follows. First, switching costs have positive effect on customer loyalty in digital content commerce environment. Second, the influence of switching costs on customer loyalty increases under conditions of high alternative attractiveness. Third, DRM convenience and breadth of use have positive effect on switching costs. The findings imply that the digital content provider should pay more attention to switching costs in addition to customer satisfaction in order to attract customers. Also, increasing the convenience of DRM use by securing the convenience of user interface and expanding the support device and increasing the service use scope by providing diverse value-added service helps to create a switching barrier. The result of the study can become a practical use in marketing strategy for maintaining existing customer. In particular, switching barrier is very important under conditions of high competition in the online music service market. This study can be used as a basis for further studies about customer retention in digital content commerce.

According to the Ministry of Health and Welfare, "Status of Registered Persons with Disabilities", the number of people with disabilities is 2,494,460 as of 2015. The lowest rates of children with disabilities were intellectual disabilities (23%) and mental disorders (33.3%). The highest rates of screening were blindness (97%), heart failure (94.4%), and hearing impairment (92.7%). 65.2% of visually impaired people who have already had a disability at the time of marriage, and the remaining 34.8% can be thought to be the cause of high incidence of disability after marriage. 'SID (Seed in the Dark)' project was designed to recapture the visually impaired parent's desire for attachment and the space difficulties of the blind who want to be a normal parent to their children through a visual impairment of a father with 7-year-old daughter. Using Gear VR(Virtual Reality), the general public was able to feel the surroundings as if they had no vision and focused on the hearing. Especially, We expressed the sound wave visually and added the hilarious game element which grasps the terrain of the maze by sound wave like a 'blind person who perceives the surroundings by sound' and catches up with daughter. People with disabilities who are far from mental illness often have a form of family with children. The fact that the rate of childbirth is high means that there is relatively little problem in daily life. It is wondered that the rate of blindness among the visually impaired, which accounts for 10% of the total disabled, is the highest at 97%. This is because, in the case of the visually impaired, the obstacle is often caused by aging, accidents, or diseases due to inherited causes rather than the visual disorder. In particular, However, the fact that there is an obstacle in vision that accounts for 83% of the body's sensory organs causes other difficulties in the nursing process of children who are non-disabled. Parents do not know the face of child when their visual impairment is severe. Parents are extremely anxious about worry that they will be lost or abducted if their children are not by their side. And that the child recognizes the disability of his or her parents other than the other parents easily and takes it as a deficiency. Since visually impaired parents are mentally mature parents with non-disabled people, they may want their children not to feel deprived of their disability. The number of people with visual impairments has been increasing since 2001, and people with impairments often become disabled. In addition, there is much research on the problem of nondisabled parents who have children with disabilities, while there is relatively little interest and research on the problem of nondisabled child rearing of parents with disabilities.
