This study examined the importance of social capital in facilitating older adults' learning and adaptation of information technology as well as alleviating depressive symptoms. At two senior community centers in South Korea, 144 adults aged 60 and older were recruited to participate in 12 week-long technology classes to learn computers, smart phone, and internet skills. At the baseline interviews were conducted to assess their health status, depression, and online social relationships. Online and offline social capital (bonding vs. bridging) was assessed (Williams, 2006). Four-step Hierarchical Linear Regression analysis was conducted to examine the effects of online social relationship on depression. Findings suggested that depressive symptoms were associated with being widowed, being unemployed, and perceiving poor health status. Adding social capital variables in the final step, older adults who perceived less stressors, greater level of subjective health and high online bonding capitals had less depressive symptoms. Only online social bonding was significant in alleviating depression. This final model explained 48% of the variance. Computer/Internet training for older adults need to consider the significant role bonding social capital can play. The findings of this pilot study provided a preliminary base of knowledge about acceptable community-based interventions for older adults.

Character conveys rich storytelling and various design elements. Domestic characters are changing and developing in various forms through SNS and offline sources, which are being developed in the aspect of contents industry. The purpose of this study is to find out and discuss the factors that character users are using Korean characters as storytelling and color factor. In terms of storytelling, they prefer adventure, fantasy, absurd and humorous stories. In terms of color, it seems that they prefer a character with simple and simple color/ warm color and warm / cute color composition. On the other hand, characters with a simple story, which is the main subject of early childhood education, fashion, or toys in the aspect of storytelling, are not preferred. In terms of color, it was shown that 4 or more colors were combined without a main color. These main colorless characters gave complex feelings that are not preferred. In terms of storytelling, it is necessary to develop and develop the contents of OSMU(One-source Multi use) through story development with adventure and fantasy structure. In terms of color, it is necessary to configure the user with a simple and simple color which is preferred by the users. Also, the assembly robot toy character needs to increase the satisfaction of the character through simple color composition. As a result of this study, the factors that satisfy the users in terms of storytelling and color are derived. These results will contribute to the development of theoretical aspects, storytelling aspects, and character design industry aspects. Despite the significance of the above paper, it was inevitable to limit the research on the analysis of the storytelling of specific characters, the research through the color analysis framework, the accurate data analysis on the color analysis, and the simple comparative analysis of one.

The purpose of this study is to examine the effects of negative experiences on social capital in order to see if the adverse functions of social media could be a barrier to the promotion of social capital through the use of social media. The study verified the moderating effect of perceived performance from social media and negative experiences(victim experience and offender experience) on social capital. The online survey was conducted in November 2019, and a total of 846 responses were used for the final analysis. As a result of the two-step regression analysis using the mean-centering technique first, it was found that the victim experience had no significant effect on the bridge social capital, but the perceived performance and the victim experience had negative moderating effect on the bridge social capital. Second, the victim experience showed a significant positive effect on the binding social capital, but showed a negative moderating effect with the perceived performance indicating positive influence on the binding social capital of the perceived performance could reduce through victim experience. Accordingly it is necessary to educate social media users on the cyber ethics, and regulation is required to mitigate risk factors for trust.

To propagate clinical disease management service, there should be built a ecosystem where service developers, service providers, device suppliers closely cooperate for u-Health platform. However, most u-Health platform is difficult to build an effective ecosystem due to the lack of secure and effective PHR(Personal Health Record) management, the lack of personalized and intelligent service, difficulties of N-screen service. To solve these problems we suggest the CDMP(Chronic Disease Management Platform) architecture. The CDMP is a software platform that provides the core functions to develop the chronic disease management services and performs a hub function for the link and integration rbetween various services and systems. CDMP is SOA based platform that enables a provision of reusability, expansibility and it provides open API where everybody can share information, contents and services easily. CDMP supports the multi platform system foN-screen service and the self management functions via SNS. In this paper, we design and implement the CDMP including PHR service based on hybrid data model for privacy preservation. Experiment results prove the effectiveness of hybrid model-based PHR service.

Due to the development of digital appliance, role of TV causes both-way by introducing IPTV, and SNS service causes big change of watching environment and residence environment. There are good conditions on the role of integrated control because it is arranged in the living room which secures movement most effectively and because family members can easily use, and the degree of use is high. Therefore, we infer user's needs by analyzing user scenario and current role of TV in home network environment. Primarily, we collect surveys of development scenario and technology which companies suggest TV applied by home network service, and secondly, we comparatively study scenario which the companies mentioned above suggest through observing user scenario, and study the role of IPTV in the future through actual scenario-based experiment by ethnography. After analyzing user scenario through case study and experiment, there are integrated device studies mainly in company study because it can be made up inside home, security and entertainment. On the other hand, there are patterns of user behavior by scenario experiment mainly in auto-tainment, security, and it showed that it is insufficient for interaction between TV and home media peripheral. Through this paper, we analyze context of home user, and based on this, we could suggest effective use of service development. Also after analyzing user form, we could know it also should be considered of ratio between activity inside home and activity outside home.

Form the observation that the successful management and operation of university websites brings about university branding effects, this paper attempts to identify the problems in relation to evaluation elements of university homepages and establish a new evaluation model that allows us to grasp the importance and priority of phased evaluation elements. In particular, we tried to secure the objectivity of the importance of department homepage evaluation elements by using AHP(Analytic Hierarchy Process). Our analysis shows that among 29 evaluation elements of department homepage, mobile service, curriculum, description of department's characteristics, guide to homepage usage/accessibility to site map and differentiated educational method were considered to be relatively important whereas the relative importance of department's slogan, differentiated image and identity, linkage to SNS, Q&A bulletin board, operation of department community, and FAQ was low. Based on the findings from our analysis, we present the basic foundation for successful management and operation of university department homepages along with a few suggestions for vitalizing those hompages.

The study examines the effect of IT education on on-line social relationship of older adults. The study group composed of 114 older adults who received IT education (computer class, internet class, and smart-phone class) at two community welfare centers in Seoul. In order to compare the effect of IT education of the study group, the control group who did not receive any IT education was recruited (N = 30). Social Capital Scale was used to measure on-line social relationship. The on-line social relationship was composed of social bonding type and social bridging type. Results showed that the study group significantly higher scores than did the control group on three subscales (emotional support, access to scare or limited resources, and out-group antagonism) of social bonding type except one subscale (ability to mobilize solidarity). With regard to social bridging type of social relationship, the study group significantly higher scores that did the control group on all four subscales (outward looking, contact with a broad rage of people, a view of oneself as part of a broader group, and diffuse reciprocity with a broader community). The findings highlight the importance of IT education for older adults to expand and increase social bonding and social bridging of social relationship.

In AI chatbot service via a messenger, a profile image of the chatbot is the first thing that users see to communicate with the chatbot. This profile image not only manages an impression about the profile owner in SNS on followers, but also makes an important impression about chatbot services on users. Thus motivated, this study investigates proper profile images tailored for the types of chatbot services and users. Specifically, I reviewed the preferred images and expressions of chatbots for each purpose of chatbot service. Then, in a case study, I collected and analyzed the representative chatbot profile images for the purpose of fun and counseling. The profile images are categorized as robot, human, animal, and abstract images. Based on these categories, I surveyed the preferred profile image of the chatbot service in either the text type or image type alternatives. For the purpose of fun, in the text version, I found that both men and women preferred a human image to others. However, in the image version, men preferred woman and robot images while women preferred cute animation character and robot images. For counseling services, both men and women preferred woman and animal images most, which is similar to the results of the text version of questionnaires as well. While both genders consistently preferred real photo images, women tend to like abstract images more than men do. I expect that the results of this study would be useful to develop the proper profile images of AI chatbot for each service purpose.
