본 연구는 3대 다발 재해 중 가장 비중이 큰 추락재해를 예방하기 위하여 특화된 재해발생 원인정보를 바탕으로 인적, 물적, 조직적, 정책적, 환경적 영향요인별 다각화된 과학적 접근방법이 마련되어야 한다는 필요성에서 출발하였다. 그동안 다양한 정책이 시도되어왔으나 실질적인 재해율 저감효과는 크지 않았는데 이는 접근방법이 근원적인 문제점을 해결하기 보다는 직접적인 차원에서 이루어졌기 때문이라고 볼 수 있다. 이에 본 연구는 전체적인 맥락 속에서 추락재해에 영향을 미치는 원인을 파악하고 중점적 관리가 필요한 요인을 발굴해내는 것을 목적으로 진행되었다. 이를 위해 영국 HSE에서 연구된 Fall from height(2003)를 우리나라의 제반 조건에 시험적으로 적용함으로써 추락재해의 근원적 원인을 찾아내려는 시도를 하였다. 본 연구의 주요 결과는 추락재해에 영향을 미치는 주요 영향 경로 도출과 이를 통한 효과적인 추락재해 저감 방법을 제시하는 것으로 요약될 수 있다.

The present study was motivated by the needs to make diversified scientific approaches toward influential factors like human, technical, organization, policy and environmental on the basis of the specialized information concerning the cause for industrial accidents in a measure to prevent the falling accident which has the biggest priority among the three major frequent industrial accidents. In this connection, diverse policies have been practiced in the meantime, with little effects in fact to reduce occurrence of industrial accidents, seemingly because such policies have been practiced on the direct dimension, instead of tries to nip in the bud of fundamental causes. This study was thus conducted with a view to determine the causes that have influence on falling accidents from the overall context and unearth the factors requiring management with priority. For this aim, "Fall from Height"(2003), a study by HSE, UK was applied to various conditions of korea as an experiment to search for fundamental causes for falling accidents. The major findings of this study might be summed up as exploring a main critical path that has influence upon falling accidents and suggesting effective ways to cut down through the critical path.

According to the data released by Korea Occupational Safety & Health Agency, construction workers suffering from falling disaster have been increasing continuously for the last five years, and in fact, small and medium construction companies’ falling disaster forms over 97% of all every year. This means that to reduce falling disaster significantly, it is needed to get rid of disaster taking place in small and medium construction companies. Here, this study aims to analyze various causes of falling disaster in small and medium construction companies, examine how those factors are correlated with one another, and suggest how to manage the risk of falling disaster effectively. According to the study results, main factors influencing falling disaster in small and medium construction companies are found as follows: Situational Awareness/Risk Perception, Fatigue/Alertness, Communications, Equipment/Facilities, and Personal Protective Equipment (PPE) in the Direct Level, Management/Supervision, Education/Training, and Planning in the Organizational Level, and Management's Commitment to Safety in the Policy Level.

This paper mainly studied the loneliness of international students in China under the influence of social support and mobile network media. Data were collected through a questionnaire survey utilizing the perceived social support scale (PSSS), mobile network media use scale, and University of California, Los Angeles (UCLA) loneliness scale. The data were analyzed using SPSS version 22.0. It was found that the total score of social support was 5.15±1.12 points, and the school support score was low. The use intensity of mobile network media was 4.06±0.55 points, and the use behavior was 4.08±0.56 points, which was above the medium level. The total score of loneliness was 45.84±7.45 points. No remarkable differences were observed in gender, length of stay in China, and Chinese proficiency (p>0.05). Correlation and regression analyses revealed that social support and mobile network media were significantly correlated with loneliness of international students. The findings confirm that social support and mobile network media have an impact on loneliness, suggesting that loneliness can be alleviated through improving social support and other means.

Virtuality is a product of the information age, and as it plays a larger role in the activities of individuals, groups and organizations, the issue of how human behavior varies between virtual and physical space has become one of the most important questions facing the management environment of today. The purpose of this article is to examine how virtuality shapes individuals’ social relationships within and outside their work groups. We developed a conceptual framework that explores the links between virtuality and social network based on computer-mediated communication theory and social network theory. Using data from 172 individuals of 42 project teams in 5 global business consulting firms, we tested cross-level hypotheses. The results of hierarchical linear modeling (HLM) indicate that virtuality significantly influences individual’s internal tie strength as well as external bridging ties. The results also show the effects of virtual process via CMC vary along with the virtual context.

Wireless and mobile technologies, especially the use of emerging social media, have become ubiquitous parts of people’s lives. The development of social media persuaded various organizations including businesses and governments around the world to join these sites in an attempt to benefit from the new powerful way of communication and interaction and take advantage of the hidden influence provided by such tools. This phenomenon significantly impacts the way individuals share their content and influence one another. This online environment provides a new perspective for current social influence theories. For example, social media can be perceived as a platform that is easily accessible for anyone with Internet connection. It is the new medium through which individuals, businesses, organizations, governments, as well as civil society, engage and interact in this information age. As such, governments can reshape their relationship with their constituents, enhance public awareness, and increase the level of citizen engagement and participation. In the 21st century, the importance of adapting to a rapidly advancing world and leveraging changes to benefit governments is widespread. The government needs to be more open and transparent about its work, and these social networking sites can help evolve a participatory, innovative, and inclusive governing model, that is, the government cannot only spread awareness regarding its policies and plans but also engage in a two-way communication where it can receive instant citizen feedback and incorporate suggestions that are provided by common people for an appealing design and proper delivery of public services, thereby resulting in an effective adoption of services. The use of Web 2.0 tools is considered a new means of communication, not only in the political field but also on the government level, to influence civic engagement, co-produce public services, shape opinions and attitude, and influence “buy-in” to mobile government (m-Government) services. Governments usually adapt business-oriented communication solutions for their own necessities, and SNSs introduces a wide perspective where citizens can have a deep participation when the government uses an appropriate citizen relation management tool. These factors contribute to e-government in twofold, namely, (1) by understanding citizens’ needs through data processing and (2) by allowing direct interaction with citizens through immediate interaction or by including ads. In the field of e-government, as a way of the government to deliver information and services through the Internet or other digital means, SNSs can contribute to positive attitudes toward government 2.0 and general trust in the government. SNSs could be a complementary tool for e-government, where citizens not only receive information but also collaborate on its generation and influence one another’s opinion on its perceived value. This study proposes that the advent of the Internet and other related technologies has increased the role of opinion leadership, which is traditionally used to amplify social and political communications and actions through social influence mechanism. Online social influence could be classified as normative when seeking compliance, identification, or internalization or informational, which is relevant to the online environment. In the literature, social influence remarkably affects SM. However, the best way to explain the underlying processes, measure the effects, and maximize the impact of social influence is still unknown. Based on these, the present study aims to determine the critical underlying processes for the online social influence that stems from opinion leadership and leads to the adoption of m-Government. It also aims to propose a framework under the Moroccan context. The main processes considered include those that focus on enhancing the perceived value of potential users to positively affect their attitude. Closely analyzed, this global perceived value is multiform, and each form corresponds to the purpose of a separate social influence process that an opinion leader can emphasize. First, perceived usefulness could mediate the impact of social influence on adoption intention through persuasion and conformity, wherein the opinion leader could showcase the added performance obtained by the potential users in using preferred government services. Second, contextual perceived value mediates the effect of social impact through influence informational processing where the influencer emphasizes showcasing information on the convenience of any context-based services (e.g., locationbased services) on their wireless and mobile devices. Third, perceived ease of use, wherein an influencer could focus on persuasion and socialization processes to effortlessly convince potential users of target services. The proper and effective use of social media could be achieved by involving genuine online opinion leaders, such as government officials; celebrities; or even experts hired from other fields, including business or civil society, to engage in a two-way interactive platform for persuasion and discussions. This approach is likely to spread awareness among citizens about the overall perceived value of m- Government services and to enable government–target citizen interaction, which will eventually help improve the design and effective adoption of government services. The present article aims to depict how governments could inform and serve people while marketing its offerings and influencing the citizens’ engagement toward the adoption of m-Government services through social media. An attempt is made to study how the different governments worldwide are using the social media platform in their governing models to promote the adoption of m-Government services. A conceptual framework is proposed by extending the mobile service acceptance model based on the critical review findings. Finally, this study calls for further research on m-Government adoption, considering the role of influencer marketing. This study culminates by providing practical, theoretical, and policy implications of the findings.

Questions about the suggestive nature of network advertisements displayed in news websites have been raised continuously. Initially, the Ministry of Gender Equality and Family discussed designating such sites as ‘Websites Harmful to Juveniles.’ However, it has been suggested that network advertisements in news websites not only deliver harmful messages to youths and adults, but they also affect the credibility of the websites in which they are displayed, and the news articles published by these websites. As such, this research analyzes how general users evaluate the suggestive nature of network image advertisements, the deceptive and exaggerative nature of network text advertisements displayed in news websites, and the influence such ads have on the credibility of the news websites and their articles. Results show that there is a positive correlation between experience of suggestive advertisements in news websites and decrease in the credibility of such websites and the articles published by them. Moreover, there is a positive correlation between perception of deceptive and exaggerative advertisements in news websites and decrease in the credibility of those news websites and their articles.

Recently, firms are operating a number of teams to accomplish organizational performance. Especially, ad hoc teams like proposal preparation team are quite different from permanent teams like R&D team in the sense of how the team forms network structure and deals with organizational learning culture and knowledge management participation efforts. Moreover, depending on the team characteristics, individual creativity will differ from each other, which will lead to organizational performance eventually. Previous studies in the field of creativity are lacking in this issue. So main objectives of this study are organized as follows. First, the issue of how to improve individual creativity and organizational performance will be analyzed empirically. This issue will be performed depending on team characteristics such as ad hoc team and permanent team. Antecedents adopted for this research objective are cultural and knowledge factors such as organizational learning culture, and knowledge management participation. Second, the network structure such as degree centrality, and structural hole is used to analyze its influence on individual creativity and organizational performance. SI (System Integration) companies are facing severely tough requirements from clients to submit very creative proposals. Also, R&D teams are widely accepted as relatively creative teams because their responsibilities are focused on suggesting innovative techniques to make their companies remain competitive in the market. SI teams are usually ad hoc, while R&D teams are permanent on an average. By taking advantage of these characteristics of the two kinds of teams, we will prove the validity of the proposed research questions. To obtain the survey data, we accessed 7 SI teams (74 members), and 6 R&D teams (63 members), collecting 137 valid questionnaires. PLS technique was applied to analyze the survey data. Results are as follows. First, in case of SI teams, organizational learning culture affects individual creativity significantly. Meanwhile, knowledge management participation has a significant influence on individual creativity for the permanent teams. Second, degree centrality influences individual creativity significantly in case of SI teams. This is comparable with the fact that structural hole has a significant impact on individual creativity for the R&D teams. Practical implications can be summarized as follows: First, network structure of ad hoc team should be designed differently from one of permanent team. Ad hoc team is supposed to show a high creativity in a rather short period, implying that network density among team members should be improved, and those members with high degree centrality should be encouraged to show their individual creativity and take a leading role by allowing them to get heavily engaged in knowledge sharing and diffusion. In contrast, permanent team should be designed to take advantage of structural hole instead of focusing on network density. Since structural hole can be utilized very effectively in the permanent team, strong arbitrators' merits in the permanent team will increase and therefore helps increase both network efficiency and effectiveness too. In this way, individual creativity in the permanent team is likely to lead to organizational creativity in a seamless way. Second, way of increasing individual creativity should be sought from the perspective of organizational culture and knowledge management. Organization is supposed to provide a cultural atmosphere in which innovative idea suggestions and active discussion among team members are encouraged. In this way, trust builds up among team members, facilitating the formation of organizational learning culture. Third, in the ad hoc team, organizational learning culture should be built such a way that individual creativity can grow up fast in a rather short period. Since time is tight, reasonable compensation policy, leader's initiatives, and learning culture formation should be done in a short period so that mutual trust is built among members quickly, and necessary knowledge and information can be learnt rapidly. Fourth, in the permanent team, it should be kept in mind that the degree of participation in knowledge management determines level of individual creativity. Therefore, the team ought to facilitate knowledge circulation process such as knowledge creation, storage, sharing, utilization, and learning among team members, which will lead to team performance. In this way, firms must control knowledge networks in permanent team and ad hoc team in a way mentioned above so that individual creativity as well as team performance can be maximized.

This paper examines the impact of two kinds network quality of horizontal network —— competitor network quality &non-competitor network quality on firm’s innovative performance, considering the moderating effect of entrepreneurship orientation and market orientation. Analysis of 165 industrial firms from Fu Jian province indicates that innovative performance is influenced by competitor network quality negatively but by non-competitor network quality positively. And results suggest that firms with higher entrepreneurship orientation prefer non-competitor network quality to competitor network quality to achieve higher innovative performance; However, firms with higher market orientation tend to choose competitor network quality rather than non-competitor network quality to create higher innovative performance. Namely，the higher the non-competitor network quality ,the better the firms innovative performance, but the higher the competitor network quality ,the lower the firms innovative performance; So, if a firm tends to reach higher innovative performance, we suggest they choose to build good relationship with non-competitor networkers, such as school, institute and government etc. rather than their competitors. As regard to the moderating effect of entrepreneurship orientation on the relationship between non-competitor network quality and innovative performance, our results indicate that the higher the entrepreneurship orientation of firms, the stronger positive relationship between non-competitor network quality and innovative performance will be. But as for the moderating effect of market orientation, the result is otherwise, the higher the market orientation, the weaker positive relationship will be between the non-competitor network quality and innovative performance.The Implications for research、theory and practice are as followed .This paper concentrates on the research of horizontal network quality, dividing horizontal network quality into two parts , one is competitor network quality ,and the other is non-competitor network quality , expanding the range of firms’ network research. It centers on the quality of network, not the network structure and the relationship quality between innovative performance. Finally, the limitation is discussed in the end of the article.

This study aims to analyze the influence of network of elderly with his or her non cohabiting children on their depression and its regional differences between urban and rural areas. The analysis is based on the sample of 1,609 elderly of 65 and above (1,011 Urban residents and 598 Rural residents) from the third time span(year 2010) to the fifth time span(year 2014) collected by the Korean Longitudinal Study of Ageing, whose research conducted by Korea Employment Information Service. First, it is found that rural elderly are more likely to suffer from depression than urban elderly. Second, it is found that rural elderly have on average a bigger number of non cohabiting children in their network, whereas geographical proximity and frequency in meeting, and economic support is stronger upon urban elderly. Third, urban elderly tend to suffer from depression as the frequency of phone calls with their non cohabiting children increases with time, and as the frequency of meeting and relationship satisfaction is decreases with time, whereas rural elderly tend to suffer from depression as their geographical proximity with their non cohabiting children is decreases with time. Based on the results of this analysis, this study further suggests practical policy interventions to prevent elderly depression.

본 연구의 목적은 조직 내 사회적 네트워크 크기에 영향을 미치는 선행변인들을 알아보고, 조직 내 사회적 네트워크 크기와 강도가 다양한 형태의 직무수행인 과업수행, 맥락수행, 적응수행에 미치는 효과를 밝히는 데 있다. 이를 위해 기업에서 근무하는 현직자 313명과 조직 내에서 이들을 잘 알고 있는 상사나 동료 54명으로부터 설문조사를 통해 자료를 수집하였다. 연구 결과, 외향성, 심리적 집합주의, 성취욕구는 조직 내 사회적 네트워크 크기에 정적인 영향을 미쳤지만, 권력욕구는 조직 내 사회적 네트워크 크기에 부적인 효과를 나타내었다. 즉, 외향적인 사람일수록, 집합주의 성향이 강한 사람일수록, 성취욕구가 높을수록, 권력욕구가 낮은 사람일수록 조직 내에서 개인이 속한 네트워크 크기가 더 컸다. 또한 조직 내 사회적 네트워크 크기는 타인평정에 의한 과업수행과 적응수행에 정적인 영향을 미치는 것으로 나타났다. 마지막으로 조직 내 사회적 네트워크 크기와 강도는 상호작용하여 과업수행에 영향을 주는 것으로 나타났다. 즉, 사회적 네트워크 강도가 약할 때보다 강할 때 사회적 네트워크 크기가 과업수행에 미치는 영향력이 더 크다는 것을 알 수 있었다. 마지막으로 연구 결과를 토대로 이 연구의 시사점 및 제한점, 그리고 추후 연구과제에 대하여 논의하였다.

The purpose of this study was to examine the influences of personal characteristics(emotional stability, extraversion, psychological collectivism, need for power, and need for achievement) on social network size in organization and the impact of social network size on a variety of job performance(task performance, contextual performance, and adaptive performance). Also, we examined moderating effect of social network strength in the relationship between social network size and job performance. Data were collected from 313 employees who had worked for more than six months in current workplace and 54 peers or supervisors who knew employees very well. Fifty-four peers or supervisors rated 313 employees' job performance. The results of correlation and hierarchical multiple regression analysis showed that extraversion, psychological collectivism, and need for achievement had positive relationships, but need for power had negative relationship with social network size in organization. Also, social network size had positive relationships with task performance and adaptive performance. There was significant moderation effect of social network strength in the relationship between social network size and task performance. Finally, the implications and limitations of this study and the directions for future research were discussed.

The objective of this study was to evaluate the influence of rainfall observation network on daily dam inflow using artificial neural networks(ANNs). Chungju Dam and Soyangriver Dam were selected for the study watershed. Rainfall and dam inflow data were collected as input data for construction of ANNs models. Five ANNs models, represented by Model 1 (In watershed, point rainfall), Model 2 (All in the Thiessen network, point rainfall), Model 3 (Out of watershed in the Thiessen network, point rainfall), Model 1-T (In watershed, area mean rainfall), Model 2-T (All in the Thiessen network, area mean rainfall), were adopted to evaluate the influence of rainfall observation network. As a result of the study, the models that used all station in the Thiessen network performed better than the models that used station only in the watershed or out of the watershed. The models that used point rainfall data performed better than the models that used area mean rainfall. Model 2 achieved the highest level of performance. The model performance for the ANNs model 2 in Chungju dam resulted in the $R^2$ value of 0.94, NSE of 0.94 $NSE_{ln}$ of 0.88 and PBIAS of -0.04 respectively. The model-2 predictions of Soyangriver Dam with the $R^2$ and NSE values greater than 0.94 were reasonably well agreed with the observations. The results of this study are expected to be used as a reference for rainfall data utilization in forecasting dam inflow using artificial neural networks.

Advocacy action was divided into case advocacy and policy advocacy, and statistical analysis was performed on each of them. The result of descriptive analysis show that case advocacy was moderate, and policy advocacy was below the average level. In case advocacy, practice level of case managers in private institutions performed better than workers at public institutions. Hierarchical regression was performed to find out if case managers’ network practice affected advocacy action. Findings showed that network practice had the greatest impact on case advocacy. Based on the results of the research, practical implications were suggested.

본 연구는 청소년의 SNS 중독 경향성이 대인관계에 미치는 영향을 알아보기 위한 서술적 조사연구이다. 본 연구의 자료는 경남 G시의 중·고등학생 250명을 대상으로 수집하였으며, 수집된 자료는 SPSS 23.0 프로그램을 활용하였고 t-test, ANOVA, 상관관계, 다중회귀로 분석하였다. 연구결과, 청소년의 일반적 특성에 따른 SNS 중독경향성 점수는 성별 (t=-2.25, p=.011), SNS사용기간(F=3.15, p=.015), 평균사용시간(F=15.87, p=.<001), SNS매체(F=3.12, p=.027), SNS매 체 사용시간(F=6.58, p=.<001)이 통계적으로 유의하게 나타났다. 주요변수의 상관관계를 검증한 결과 SNS 중독경향성은 대인관계와 통계적으로 유의한 정적상관관계를 갖는 것으로 나타났으며, 대인관계 영향요인은 SNS 중독경향성(β=-.64, p=.<001)으로 37%의 설명력이 있는 것으로 나타났다.

This study was narrative research study to find out the effect of adolescents' social media addiction tendencies on interpersonal relationships. This research data was collected from 250 middle·high school students in G city, Gyeongnam and collected data was analyzed with t-test, ANOVA, Pearson’s correlation, Multiple regression coefficient using SPSS 23.0 program. SNS addiction tendency scores according to general characteristics of adolescents were gender (t= -2.25, p = .011), duration of SNS use (F= 3.15, p= .015), average usage time (F= 15.87, p=. 001), SNS media (F= 3.12, p= .027), and SNS media usage time (F= 6.58, p= .001) were statistically significant. As a result of verifying the correlation of main variables, addiction tendency of SNS had statistically significant static correlation with interpersonal relationships. Influencing factors of interpersonal relations were Addiction tendency of SNS(β=-.64, p=.<001) Interpersonal relationship explained 37% of the total variability.

본 연구에서는 산업의 혁신패턴이 기술체제의 특성에 따라 다르다는 산업별 혁신체제론적 접근에 입각해 기업간 연결수, 연결강도, 연결망내 위치 등 기업의 연결망 특성이 생산성에 미치는 영향을 사회적 연결망 분석(social network analysis) 방법을 적용하여 분석하였다. 한국기업데이터(주)의 「2011년 기업정보」 DB 자료를 이용하여 제조업을 공급자지배산업, 생산집약적 산업, 과학기반산업으로 분류하고 연결망 특성이 기업의 총요소생산성에 미치는 영향을 실증 분석하였다. 실증분석 결과, 섬유․의복 등 지식기반이 주로 일반적 명목지(generic knowledge)에 의존하고 외부 공급기업의 혁신성과를 활용하는 공급자 지배산업에서는 많은 기업들과 약한 연결을 맺거나, 구조적 틈새(structural hole)를 활용해 지식전파의 중개역할을 하는 기업의 생산성이 높은 것으로 나타났다. 이에 비해 기계․자동차, 철강금속, 석유화학, 등 지식기반이 특수적 암묵지(tacit knowledge)에 의존하고 기존 기술의 심화를 추구하는 생산집약적 산업에서는 적은 수의 기업들과 강한 연결을 맺거나, 연결망의 중심에 가까이 위치한 기업들의 생산성이 높은 것으로 나타났다. 한편 전자통신․정밀기계․의약 등 과학기술진보의 성과를 흡수하여 신기술 개발을 추구하는 과학기반산업에서는 기술적 기반이 유사한 기업들끼리 클러스터 형성이 활발할수록 생산성이 높은 것으로 나타났다. 이상의 분석결과로부터 혁신클러스터정책과 중소기업 기술지원정책이 혁신패턴과 기업간 연결망의 산업적 특성을 고려해 모색되어야 한다는 함의를 얻고 있다.

This paper aims to analyse different sectoral innovation effects incurred by knowledge spillover, which can be verified by the different transaction network characteristic effects on the sectors. We used Korean Enterprise Data company providing database [2011 Company Information] to categorize the industrial sectors on the technological basis and to analyse the effects by the industrial categories using regression models. We summarize analysis as follows. The theory that companies in the middle of more dense weak transactions and the companies playing role of mediating knowledge propagation using the ’structural holes’ have better outcomes, in the supplier dominant industries such as textile industries, which are based on the generic and incremental knowledge, is supported empirically. On the contrary, the production concentrative industries such as machinery-automobile or iron-metal, oil-chemistry industries which are based on the tacit knowledge, have companies showing better outcomes when the companies have small number of strong relations or when the companies is more close to the center of the network. Also we successfully proved empirically that higher cluster coefficient, which is result of intense clustering activities between similar technical level companies leads to better productivity in the science knowledge based industry such as electronics and medical industries. This results imply that the research on the industrial clustering and subcontracting related policies should consider different technological system by industries.

목적 : 본 연구의 목적은 지역사회에 거주하는 일반노인들의 사회적지지, 사회적관계망이 삶의 질에 미치는 영향을 확인하고자 한다. 연구방법 : 연구 대상은 부산광역시, 경상북도 경주시에 소재한 장애인복지관, 보건소, 노인복지관 13곳의 건강한 남·여 노인 75명을 대상으로 하였다. 일반적 특성, 인지능력, 사회적지지, 사회적관계망, 삶의 질이 포함된 설문지를 통해 조사하였고, 대상자 선정 기준에서 제외된 12명을 제외한 63명을 대상으로 분석하 였다. 결과 : 삶의 질에 영향을 미치는 변인들의 상관관계를 분석 한 결과 접촉빈도(p<.05)와 친밀도(p<.001) 그리 고 사회적지지(p<.001)에서 정적인 상관관계가 나타났다. 최종적으로 지역사회거주 일반노인의 삶의 질에 영향을 미치는 변인으로는 친밀도(p<.001)로 분석되었다. 결론 : 지역사회 거주하는 일반노인들의 친밀도가 삶의 질에 영향을 미치는 주요 변인으로 파악되었다. 수 동적인 삶을 살아가는 노인이게 있어 사회관계망의 질적 특성인 친밀도의중요성을 확인할 수 있었다.

Objective : The purpose of this study is to identify the impact of the social support and social network on the quality of life of the elderly residing in a local community. Method : The subjects of this study were 75 healthy old men and women of 13 sites of welfare centers for the disabled and public health centers and senior welfare centers in Busan and Gyeongju. A survey was conducted with a questionnaire that include general characteristics, cognitive ability, social support, social network and quality of life. The analysis was made on 63 replies except 12 subjects who had been excluded by the subject selection criteria. Result : As a result of analyzing correlation of variables affecting life quality, there was positive correlation in contact frequency(p<.05), intimacy(p<.001), and social support(p<.001).
