Social Media transformed the mass media based information traffic, and it has become a key resource for finding value in enterprises and public institutions. Particularly, in regards to disaster management, the necessity for public participation policy development through the use of social media is emphasized. National Disaster Management Research Institute developed the Social Big Board, which is a system that monitors social Big Data in real time for purposes of implementing social media disaster management. Social Big Board collects a daily average of 36 million tweets in Korean in real time and automatically filters disaster safety related tweets. The filtered tweets are then automatically categorized into 71 disaster safety types. This real time tweet monitoring system provides various information and insights based on the tweets, such as disaster issues, tweet frequency by region, original tweets, etc. The purpose of using this system is to take advantage of the potential benefits of social media in relations to disaster management. It is a first step towards disaster management that communicates with the people that allows us to hear the voice of the people concerning disaster issues and also understand their emotions at the same time. In this paper, Korean language text mining based Social Big Board will be briefly introduced, and disaster issue detection model, which is key algorithms, will be described. Disaster issues are divided into two categories: potential issues, which refers to abnormal signs prior to disaster events, and occurrence issues, which is a notification of disaster events. The detection models of these two categories are defined and the performance of the models are compared and evaluated.

Purpose: This study focused on the societal changes associated with the entry into an ultra-aged society and the increase in single-person households. The core objective of this research is to investigate how social intelligent robots can bring about positive changes in the lives of individuals in single-person households and how such changes influence user satisfaction and the intention to use these robots. Methods: The study employed a cross-sectional analysis using a structural equation model. A survey designed to assess the impact of social intelligent robots' characteristics, such as perceived encouragement, empathy, presence, appearance, and attachment, on user satisfaction and usage intentions was conducted. Data were collected from a total of 335 users and analyzed using the structural equation model. Results: In the characteristics of social intelligent robots for single-person households, it was found that empathy, presence, and attachment significantly influenced satisfaction, while perceived encouragement, empathy, and attachment significantly influenced usage intentions. The research results indicate differences between enhancing user satisfaction and increasing the intention to use social intelligent robots. The findings suggest the essential need for a user-centric approach in the design and development of social intelligent robots. Additionally, it was observed that emotional support plays a crucial role in users' experiences with social intelligent robots. Conclusion: This study verified the impact of social intelligent robots on satisfaction and usage intentions based on users' experiences. It examined the influence of linguistic, visual, and personal characteristics of robots on user experiences, providing insights into how technological and human aspects of social intelligent robots interact to shape user satisfaction and usage intentions. Consequently, the study confirmed that social intelligent robots can bring positive changes to human life, emphasizing the necessity for the advancement of robot technology in a human-centric direction.

본 연구는 백두대간 관광개발에 따른 경제적 사회적 환경적 요인이 농산촌주민들이 인지하는 지역애착과 관광개발태도와 개념적으로 어떠한 구조를 이루고 있는가를 분석하기 위하여 수행되어졌다. 연구방법은 이들 요인들 상호간의 구조관계를 공변량구조모형의 일종인 LISREL 분석에 적용하였다. 조사대상지는 백두대간이 분포하고 있는 경상북도 영주와 문경시 지역주민 356명을 대상으로 면접설문조사를 실시하였다. 분석결과 경제적 편익이 사회적 요인과 환경적 요인보다도 직 간접적으로 지역주민의 관광개발태도에 가장 긍정적인 영향을 미치는 것으로 나타났으며, 사회적 요소는 지역애착에 미치는 영향요인으로는 분석된 반면, 경제적 환경적 요소는 지역애착에 영향을 미치는 변수가 아닌 것으로 나타났다. 마지막으로 관광개발태도는 지역애착에 의하여 긍정적인 영향을 받는 것으로 나타났다. 이러한 결과를 종합하면 일반적인 사회교환이론과는 달리 백두대간 관광개발에 대하여 관광산업과 관련된 주민이 아니라 하더라도 경제적 편익에 대하여 긍정적인 태도를 보이면서, 동시에 부정적일 수 있는 사회적 환경적 요인에 대하여도 긍정적인 태도를 보이고 있다.

취약계층에게 사회서비스를 제공하는 사회복지시설은 자원의 결핍으로 클라이언트를 위한 서비스를 제공하는데 재정적인 한계에 직면한 상황이다. 그 근본적인 이유는 정부지원금의 부족에도 기인하지만 시설이 지역사회의 풍부한 민간자원을 개발하는 기술이 부족한 탓도 있다. 이에 본 연구에서는 후원에 초점을 두어 시설의 자원동원에 영향을 주는 요인을 규명함으로써 시설들이 효과적으로 자원을 동원할 수 있는 방안을 마련하였다. 본 연구를 위해서 사회복지시설의 후원업무를 담당하거나 관여를 하는 직원을 대상으로 우편조사를 실시하였다. 조사대상 시설은 이용시설 3유형(사회복지관, 노인복지관, 장애인복지관)시설과 생활시설 6유형(아동시설, 노인시설, 장애인시설, 여성시설, 정신요양시설, 부랑인시설)시설이었다. 총 1,510개소의 대상 중 조사에 응한 시설은 이용시설 293개소, 생활시설 632개소로 설문응답률은 62%에 이른다. 본 연구의 종속변수는 자원동원실태로써 후원자수(결연후원자와 시설후원자의 합), 후원액(결연후원액과 시설후원액의 합), 후원물품 현금환가액을 설정하였고, 이용시설과 생활시설에서 각각 세 모델을 구성하였다. 독립변수는 기존의 연구 결과를 참고로 하여 자원동원에 영향을 주는 세 유형인 지역환경요인, 조직요인, 후원개발요인을 선정하였다. 분석을 위해서 중다회귀분석(multiple regression analysis)을 실시하였다. 분석결과 본 연구에서 중점적으로 보았던 후원개발요인은 많은 모델에서 유의한 것으로 판명되었다. 후원자수, 후원액, 후원물품(이용시설 제외) 모델에서 모두 6변수로 구성된 자원개발요인은 최소한 1개의 변수는 유의한 것으로 밝혀졌다. 후원개발을 위해 후원을 위한 전담부서나 직원을 두며, 후원자 관리를 위한 전산 프로그램을 사용하는 시설, 그리고 후원자 모집 및 관리를 하는 시설이 그렇지 않은 시설보다 자원동원결과가 더 긍정적이었다. 특히 후원자관리를 위한 전산 프로그램 사용은 생활시설 모델에서는 유의한 것으로 나타났다. 이 밖에 생활시설의 후원자수 모델에서는 소재지(대도시)가 유의하였고, 후원액 모델에서는 생활시설의 경우 시설유형(여성시설), 운영기간, 직원 수가 유의하였다. 후원물품 모델에서는 이용시설의 경우 지역 생활환경(중상층), 생활시설의 경우 시설유형(노인, 아동, 정신요양시설), 운영기간이 유의하였다. 이러한 분석결과를 바탕으로 본 연구에서는 사회복지시설이 자원을 활발하게 동원하기 위해서는 후원개발을 위한 조직이나 인력을 배치해야 하고, 후원자 관리를 위한 전산 프로그램 및 후원자 모집 및 관리 프로그램을 활용해야 함을 제시하였다.

External social support for family can be an important resource for families to overcome economic pressure, and can be a way to understand the concept and process of family resilience in the context of Korean economic crisis. To explore the role of external social support that alleviates the negative effects of economic pressure on marital satisfaction, the buffering effects were tested in two ways. First, the interaction effect between external social support and economic pressure on marital satisfaction was tested using hierarchical linear regression model. Second, the scores of marital satisfaction were plotted by the median scores of economic pressure and external social support. Results from the analyses of 191 couples (382 husbands and wives) indicated that external social support help families by buffering the negative effects of economic pressure on marital satisfaction by interacting with economic pressure.

The purpose of this study is to propose a strategy model for engineering education for citizen through the connection between colleges of science and engineering and science museums as a way to achieve citizen science. For this model, the role of universities was redefined as social contributions through engineering education from the perspective of knowledge triangle and university entrepreneurship. In addition, the science museum was re-examined as an engineering education platform and selected as an institution that supports the contribution of colleges to society. For practical model development, the connection types of these two institutions were analyzed as case studies and interview to collect opinions from experts in the science museum. In this process, convergence education content development, reinforcement of college-science museum linkage, infrastructure construction, development of college resource utilization plans, and maintenance and expansion of educational programs diversification were derived as components for model development. Based on this, engineering education model for citizen was presented that matches educational programs according to the type of participation of colleges including key factors and considerations.

Objective: This study examined the relationships between negative affect, social support, and career maturity among adolescents. Methods: The participants in this study comprised 260 $1^{th}$ junior high school students in a Seoul metropolitan area. They completed questionnaires on level of negative affect, social support, and career maturity. Data were analyzed by means of basic descriptive statistics, Pearson's correlations, and multiple and hierarchical regression analyses. Aiken and West's method was used to determine the interactive model's modality. Results: The major findings were as follows: First, negative affect was negatively correlated with social support and career maturity. Social support was positively correlated with career maturity. Second, significant interaction effects were found between negative affect and social support on career maturity; that is, for male students, significant interaction effects were found between negative affect and social support (parent support) on career maturity (career determinacy/career independence). For female students, significant interaction effects were found between negative affect and social support (peer support) on career maturity (career confidence/career readiness/career determinacy/career independence). Conclusion: These results suggest the need to intervene in relation to social support (parent support/peer support) and to improve career maturity among adolescents.

With the rapid development of the Internet and the Mobile Internet, social communication based on the network has become a life style for many people. WeChat is an online social platform, for about one billion users, therefore, it is meaningful to study the spreading and evolution mechanism of the rumor on the WeChat social circle. The Rumor was injected into the WeChat social circle by certain individuals, and the communication and the evolution occur among the nodes within the circle; after the refuting-rumor-information injected into the circle, subsequently,the density of four types of nodes, including the Susceptible, the Latent, the Infective, and the Recovery changes, which results in evolving the WeChat social circle system. In the study, the evolution characteristics of the four node types are analyzed, through construction of the evolution equation. The evolution process of the rumor injection and the refuting-rumor-information injection is simulated through the structure of the virtual social network, and the evolution laws of the four states are depicted by figures. The significant results from this study suggest that the spreading and evolving of the rumors are closely related to the nodes degree on the WeChat social circle.

Purpose - This study examines the positive impact of the social distance between producers and users of online content, investigating and analyzing the most popular Web content. In addition, it tries to elicit the matching effect that appears when the individuals'cultural background is consistent with social distance. Research design, data, and methodology - We collected and analyzed actual data about 4,981 videos clips on YouTube, looking at six countries in order to verify the content of this study. Based on the results of the data analysis, the study conducted behavioral measurements on popularity, social distance, culture, and user engagement. The unit of analysis was the content and we collected information about the content producers and the content records. We controlled the views, comments, likes, calendar dates, and ages in the empirical models. The data was collected in 2011, with the records coming from South Korea, Japan, China, U.S., German, and France. A total of 4,980 elements were analyzed in the model. The empirical model estimated is the bivariate negative binomial distribution (NBD) model. Results - It turns out that there is a possibility that the matching effect can be diminished by variables that reflect the psychological involvement of user engagement. This study proposes academic and practical implications based on these research results. This research shows the positive effect of social distance between users and producers on the increased performance of the online content. We find the effect of social distance to be a stronger tendency in collectivism. The collectivists follow their sense of friendship and intimacy in their culture and, the social congruence effect can be found there as well. The effect, however, could erode in a social case where users are motivated by strong intrinsic and psychological factors. In addition, user engagement complicates the process of user decision making regarding the information. Conclusions - This study examines how the differential effects of social distance caused by culture could disappear through user commitment as a complicated user motivation. Some potential implications are as follows. First, a firm in the collectivism culture has to communicate based on the social distance. In fact, most online channels do not have a function that indicates the social distance as measured by favorites or subscribers. This function could help increase the performance of the content in online channels, but this increasing effect can only be found in a collectivist culture. Based on this, the firms have to communicate and announce to users the actual social distance between users and producers. Second, firms should develop a system that discovers the social distance and culture and shows these measures to users and producers, since the congruence effect between social distance and culture is found only for low user engagement. The firms can take the advantage of the congruence effect only for the development of the social distance and culture visualized system.
