Purpose: This study was done to identify the relationship of malnutrition, social network and health-related quality of life and to investigate the main factors influencing health-related quality of life in elders. Methods: The research design was a descriptive survey design using a convenience sampling. Data were collected by self-report questionnaires from 196 elders. Data analysis was done using SPSS 18.0 pc+ program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. Results: The average score for health related quality of life was 3.33 (SD=0.86). Differences in health-related quality of life were statistically significant according to age, gender, occupation, presence of spouse, monthly income, source of income, economic status, medicine, and existence of chronic disease. Health-related quality of life was significantly correlated with malnutrition and social network. Major factors affecting health related quality of life for elders were malnutrition, occupation, age, social network, and economic status which explained 52.0% of the variance in health related quality of life. Conclusion: Findings provide a basis for developing nursing interventions to improve health-related quality of life. Future studies are needed a wide variety of variables that might influence health -related quality of life in elders.

This study investigates passenger-authored online reviews of airline services using social network analysis to compare the differences in customer perceptions between full service carriers (FSCs) and low cost carriers (LCCs). While deriving words with high frequency and weight matrix based on the text analysis for FSCs and LCCs respectively, we analyze the semantic network (betweenness centrality, eigenvector centrality, degree centrality) to compare the degree of connection between words in online reviews of each airline types using the social network analysis. Then we compare the words with high frequency and the connection degree to gauge their influences in the network. Moreover, we group eight clusters for FSCs and LCCs using the convergence of iterated correlations (CONCOR) analysis. Using the resultant clusters, we match the clusters to dimensions of two types of service quality models ($Gr{\ddot{o}}nroos$, Brady & Cronin (B&C)) to compare the airline service quality and determine which model fits better. From the semantic network analysis, FSCs are mainly related to inflight service words and LCCs are primarily related to the ground service words. The CONCOR analysis reveals that FSCs are mainly related to the dimension of outcome quality in $Gr{\ddot{o}}nroos$ model, but evenly distributed to the dimensions in B&C model. On the other hand, LCCs are primarily related to the dimensions of process quality in both $Gr{\ddot{o}}nroos$ and B&C models. From the CONCOR analysis, we also observe that B&C model fits better than $Gr{\ddot{o}}nroos$ model for the airline service because the former model can capture passenger perceptions more specifically than the latter model can.

China has the largest number of the user of web 2.0 such as messengers and blogs, as of 2008 year. Chinese Internet digital market will grow from $85 billion in 2007 to $264 billion in 2015. The importance of Chinese Internet business is increasing, because of its size and growth potential. This research is focused on following two questions. First, what are the major characteristics of social networking services in China? In order to find out the answer about this question, the case study on Tencent QQ and Sina Poco, the most representative social networking services company in China, was done. And the reason of the use of social networking services, their contents, and the attitude toward the paid service were identified. Second, what are the major factors influencing the use of social networking services in China. User participation, network effect, usefulness, and system quality were inferred as the factors influencing the use. These factors were based on motivation theory, technology acceptance model, and the related research papers. This research model was proved by data analysis using Partial Least Square. As results, the use of social networking services was influenced by usefulness, network effect, user participation, and system quality. But social influence was not significant of the use of social networking services.

전 세계적으로 노령화 문제가 사회적 이슈로 대두되고 있는 가운데, 노인이 느끼는 전반적인 삶의 질 (Quality of Life, QoL) 이 하락하는 문제가 사회 전반에 걸쳐 중요한 문제로 인식되고 있다. 이에 다양한 형태로 발생하고 있는 노인들의 문제를 해결하기 위하여 노인학, 사회 복지학 등의 분야에서 많은 연구가 진행되고 있다. 이 중 노인의 사회적 관계 (Social Network, SN) 를 강화, 확장하여 노인의 삶의 만족도 향상을 추구하고자 하는 연구를 찾아볼 수 있다. 이러한 관점에서 노인의 사회적 관계를 인터넷을 이용해 개선함으로써, 노인의 삶의 질을 향상시키고자 하는 것이 본 연구의 궁극적인 목표이다. 이에 본 연구의 세부적인 목적은 현재 젊은 층을 중심으로 많이 사용되고 있는 SNS 를 노인들이 사용하지 않는 이유에 대한 분석, 노인을 위한 SNS 의 핵심적인 기능적, 서비스적 요소를 파악하는데 있다. 이를 위해 현재 인터넷을 잘 활용하고 있는 60 세 이상의 노인 22 명을 대상으로 개별 인터뷰, 참가자가 사용하는 서비스 분석, FGI 의 3 가지 방식으로 데이터를 수집하였다. 이후 수집한 데이터를 이용하여 정성적 분석 방법으로 Casual Network 를 도출하였으며, 정량적 분석 방법인 Laddering 분석으로 Hierarchical Map 도출하여 비교하였다. 또한 도출된 결과가 노인들만의 특징인지를 파악하기 위하여 대학생, 직장인 각 10 명씩을 대상으로 노인을 대상으로 한 연구 방식과 동일한 방법으로 데이터를 수집, 분석 하였다. 최종적으로 본 연구는 사회감성적 선택 이론 (Socioemotional Selectivity Theory, SST)를 바탕으로 인터넷에서의 Social Network 활동도 오프라인과 유사한 특징을 가지고 있으며, 현재 친하게 지내고 있는 사람들을 중심으로 SN 을 강화시키려 하는 강화형 타입과 새로운 SN을 생성하기 위하여 노력하는 확장형 타입으로 구분할 수 있었다. 추후 이러한 특징들을 반영하여 노인들을 위한 SNS 가 지녀야 할 기능적, 시스템적 요소를 제안하고, 추후 연구 및 SNS 개발과 관련한 계획을 정리하였다.

Purpose: The purpose of this study is to identify relationships between acculturation, social network, and health-related quality of life (HRQOL) among Korean-Chinese immigrants. Methods: A cross-sectional descriptive study was conducted with 147 Korean-Chinese immigrants who were residing more than 1 year in Korea. Physical and mental dimensions of HRQOL were assessed by Short Form-12 Health Survey that consisted of a physical component summary (PCS) and a mental component summary (MCS). Data were analyzed with Pearson's correlation and multiple regression. Results: The mean PCS score was $41.14{\pm}10.72$ and the mean MCS score was $49.09{\pm}11.31$ (possible range 10-70). Depression (${\beta}$=-6.43) and Social network frequency (${\beta}$=2.44) explained 28.4% of the variance in PCS while depression (${\beta}$=-11.54) and visiting clinic/hospital (${\beta}$=-4.00) explained 34.3% of the variance in MCS. Acculturation was not significantly associated with HRQOL. Conclusion: This study confirmed that the social network frequency influences HRQOL among Korean-Chinese Immigrants. The findings suggest that social network analysis should be considered in the process of developing health intervention strategies for Korean-Chinese immigrants.
