In Korea, there are a total of 8 creative cities selected by UNESCO in 7 fields. UNESCO creative city refers to a network of creative cities with international level of experience, knowledge, and expertise in the field of culture and arts. Based on the PCSI 2.0 model, this study conducted a satisfaction survey of experts on Daegu's Creative City. Variables were composed of service quality, social responsibility, inconsistency, satisfaction and performance, and service quality was measured by dividing it into three categories: content quality, delivery quality, and environmental quality. Therefore, this study verified that the three types of quality, social responsibility, and inconsistency affect satisfaction, and that satisfaction affects performance. As a result of the study, it was found that the three service quality did not directly affect satisfaction, but rather affected satisfaction through inconsistency. So, 3 out of 10 hypotheses were rejected.

As Social Welfare Service Act was revised in 2011 and its enforcement decree was revised in 2012, the function of local social welfare center was classified into 3 functions such as case control function, service supply function and local society systematization function. Therefore, from 2013, local social welfare center faces the assignment to establish its status as a core subjectivity of local social welfare while maintaining function, role, business, program, service and organization system required for local social welfare center. Currently, there are internal and external limit factors for local social welfare center to perform its original function. The external limit factors are competition with similar organization, diversification of welfare desire depending on social change, insufficient service network construction and lack of partnership between private sector and government. The internal limit factors are lack of local social organization's ability, program issue, insufficient resource, insufficient manpower, etc. In order for local social welfare center to overcome the limit factor and establish the core status for improving the life quality of resident, it should concentrate its ability on local society systematization, construct human & material support network related to local social welfare, minimize social education program and simple relief project gradually, suggest the reasonable direction for village to nurture resident organization, develop the program based on the research on local resident's desire and create the partnership between private sector and government.

Internet-based social and interactive video applications have become major constituents of the envisaged applications for next-generation multimedia networks. However, inherently dynamic network conditions, together with varying user expectations, pose many challenges for resource allocation mechanisms for such applications. Yet, in addition to addressing these challenges, service providers must also consider how to mitigate their operational costs (e.g., energy costs, equipment costs) while satisfying the end-user quality of service (QoS) expectations. This paper proposes a heuristic solution to the problem, where the energy incurred by the applications, and the monetary costs associated with the service infrastructure, are minimized while simultaneously maximizing the average end-user QoS. We evaluate the performance of the proposed solution in terms of serving probability, i.e., the likelihood of being able to allocate resources to groups of users, the computation time of the resource allocation process, and the adaptability and sensitivity to dynamic network conditions. The proposed method demonstrates improvements in serving probability of up to 27%, in comparison with greedy resource allocation schemes, and a several-orders-of-magnitude reduction in computation time, compared to the linear programming approach, which significantly reduces the service-interrupted user percentage when operating under variable network conditions.

Although the theater performance industry is a typical cultural content industry, the support at the national level has been poor and the theater workers tend to focus on individual efforts rather than active interaction with the theater environment. Therefore, there is a growing need for effective revitalization of the theater industry, which should be found in improving the quality of interaction between the theater and the theater environment. Therefore, the purpose of this study is to analyze the effects of theater actors (theaters, theater organizations) on the activation of plays by the interaction of politics, business, and technology, the main environment of the plays. For this, social network analysis was performed. As a result of the study, it was found that mediation centrality significantly influenced the visibility of theater actors. This means that the more the theater actors are at the center of information and resource flows to the elements of the theater environment, the more visibility becomes. This shows that the theater must actively acquire technology, create an avant-garde, and endeavor to expand its influence and outreach through active interaction with politics and corporations.

As the volume of internet and web contents have shown an explosive growth in recent years, lately contents recommendation system (CRS) has emerged as an important issue. Consequently, researches on contents recommendation method (CRM) for CRS have been conducted consistently. However, traditional CRMs have the limitations in that they are incapable of utilizing in web 2.0 environments where positions of content creators are important. In this paper, we suggest a novel way to recommend web contents of high quality using both degree of centrality and TF-IDF. For this purpose, we analyze TF-IDF and degree of centrality after collecting RSS and FOAF. Then we recommend contents using these two analyzed values. For the verification of the suggested method, we have developed the CRS and showed the results of contents recommendation. With the suggested idea we can analyze relations between users and contents on the entered query, and can consequently provide the appropriate contents to the user. Moreover, the implemented system we suggested in this paper can provide more reliable contents than traditional CRS because the importance of the role of content creators is reflected in the new system.

This research explores diachronic fashion design trends through a structure analysis of a connection network based on fashion show concepts implemented by modern fashion designers from S/S 2009 to F/W 2013. The findings from this research are as follows. First, four categories affect the inspiration and thinking of design: the experience of the designer, social atmosphere and phenomena, natural sensitivity (or formative characteristics of natural objects), and the influence and quality of other fields. Second, in cases where the designers' experiences influenced design inspiration and thinking, designers express personal memories with keywords like high school, grandmother's closet, prom, beauty and the beast, heritage, past, and reminiscence through design elements such as lines, silhouettes, materials, and colors. Third, the representative example of the social atmosphere and phenomena that influenced design inspiration and thinking was the 2008 Global Financial Crisis that reflected the social climate through design concepts of keywords such as Recession, Black, Economy, US, Depression, Gray, Dark Age, White and New York. Fourth, inspired by nature and the formative characteristics in design, the designers employed ornamental elements to collections and design concepts that focused on nature words connected to light, sun, wild, dirt, rock, moss, and trees. Fifth, the designers took their ideas from different fields of personal interest in the arts, science and humanities (sports, architecture, sculpture, painting, and literature) that were decisive in determining materials, design colors and silhouettes. The theme of architecture was analyzed as a central element that had an ongoing impact on the concepts of designers.

The purpose of this study was to examine the self-rated health and to find various factors affecting it for elderly women in a rural community, to provide data necessary to establish health promotion programs for elderly. The subjects of the study included a total of 245 women with above 70 years of age reside in one rural community. VAS (Visual Analogue Scale) for self-rated health, Lawton's physical & instrumental activity of daily living scales, social network were evaluated. The results of the study were as follows: 1. The self-rated health of the elderly women were measured on a 100 point(VAS) scale and the score was 53.6, indicating that women rated their health as moderate. 2. Factors such as income(p=0.008), family size(p=0.031), the level of ADL(p=0.039), urinary symptom(p=0.039), nocturia(p=0.001), visual difficulty(p=0.023), the number of chronic diseases(p=0.015), presence of arthritis or neuralgia(p=0.015), social network(p=0.002), housework assistant(p=0.008), emotional support(p=0.031) were significantly related to self-rated health. 3. Through the stepwise multiple regression, social network, family size, visual difficulty, and housework assistant were identified as significant predictors of self-rated health(p<0.05), explaining $21.0\%$ of the variance of the dependent variable. Better understanding of the determinants of healthy aging hopefully will lead to effective interventions to improve the quality of life of the elderly.

Due to the advancement of virtual reality technology, virtual idols are widely used in industrial and cultural content industries. However, it is difficult to utilize virtual idols' social perceptions because they are not properly understood. Therefore, this paper collected and analyzed YouTube comments to identify differences about social perception through comparative analysis between virtual idols and general idols. The dataset was constructed by crawling comments from music videos with more than 10 million views of virtual idols and more than 10,000 comments. Keyword frequency and TF-IDF values were derived from the collected dataset, and the connection centrality CONCOR cluster was analyzed with a semantic network using the UCINET program. As a result of the analysis, it was found that virtual idols frequently used keywords such as "person," "quality," "character," "reality," "animation," while reactions and perceptions were derived from general idols. Based on the results of this analysis, it was found that while general idols are mainly evaluated with their appearance and cultural factors, social perceptions of virtual idols' values are mixed with evaluations of cultural factors such as "song," "voice," and "choreography," focusing on technical factors such as "people," "quality," "character," and "animation." However, keywords such as "song," "voice," "choreography," and "music" are included in the top 30 like regular idols and appear in the same cluster, suggesting that virtual idols are gradually shifting away from minority tastes to mainstream culture. This study aims to provide academic and practical implications for the future expansion of the industry and cultural content industry of virtual idols by grasping the social perception of virtual idols.

If we observe the formation of communities of people and participation methods within them, we can see that those communities are developing more efficiently due to the penetration of smart phones and the growth of SNS. This trend also has an impact on information sharing activity between people and enables more active information sharing than ever before. But information sharing on SNS does not just involve the SNS users sharing information with each other. Important factors affecting the information sharing activities include the type of relationship between the users and the attitude of the information sharing individuals. Accordingly, this study selected perceived social support, perceived social influence, and perceived network structure as the factors that affect the continuous intention of people to use SNS, and performed a higher order factor analysis on those factors. Between continuous intention to use SNS and intention to share information, we selected relationship quality and information sharing behavior and executed a path analysis between the factors. We carried out an empirical analysis by utilizing SPSS 18.0 and SmartPLS 2.0 as analysis tools. Using these tools, we investigated the factors influencing continuous intention to use SNS, and tested the significance between the role and path of relationship quality and information sharing behavior between continuous intention to use SNS and intention to share information.

Purpose: The size of the salad consumption market has expanded since Covid-19, and continuous growth is predicted. Therefore, by extracting influential core purchasers in the salad consumption market and analyzing their purchasing behaviors and consumer types, this study intended to provide basic data for establishing a marketing strategy. Methods: The analysis data is the purchasing data of 576 people who have purchased salads between 2016 and 2020 (panel data of the Rural Development Administration), and in the social network analysis, the centrality structure was analyzed. Results: First, in the results of analyzing the causes of the rapid increase in salad consumption in 2020, it was found that the increase in consumption of new purchasers (n=102) had little effect. The existing consumer type (n = 474), which has been the majority of the salad consumption market so far, were consumers with stable income. However, the results of study indicated that the type of consumers has expanded since low-income class as well as high-income class increased consumption of purchasing salad. Second, in the results of analyzing the types of key purchasers with great influence in the salad consumption market, there was a difference from the results of frequency analysis in age, number of family members, existence/absence of children, and income decile. This suggests that there should be a difference between the type of customers according to the apparent quantitative figure and the actual influential purchasers. Third, in the results of analyzing the salad purchasing behaviors of core purchasers, the purchasing site for existing purchasers was large-scale marts and for new purchasers it was corporate-type supermarkets. Purchases were concentrated on Saturdays for both existing and new purchasers. As for the purchased products, existing purchasers had a high preference for products made of chicken, and new purchasers had a high preference for vegetable/fruit salad. In particular, in the results of purchased products by age group, in the case of 50s and 60s, it was an interesting result that there was a difference between the products purchased by the existing and new purchasers even though they were the same age. Conclusion: When establishing a marketing strategy in the salad consumption market, it is necessary to pay attention to the purchasing behavior of key buyers.
