노년기의 사회적 관계와 인지기능은 상호 밀접한 관계가 존재한다. 사회적 관계(social relation)는 구조적 특성과 이에 대한 인지적 정서적 평가를 반영하는 질적 특성으로 구분되며, 최근 노년기의 사회적 관계와 관련하여 사회적 고립(social isolation) 개념이 부각되고 있다. 사회적 고립은 사회연결망, 가구형태, 사회참여 등 객관적 차원과 지각된 사회적 지지에 대한 결핍과 외로움 등 주관적 차원으로 구분되는 다차원적인 이론적 구조를 가진다. 노년기 대인관계갈등 역시 인지기능과 밀접한 관계가 존재한다. 본 연구에서는 사회적 관계의 구조적 특성을 나타내는 객관적 사회적 고립과, 질적 특성을 나타내는 주관적 사회적 고립, 대인관계갈등이 노년기 연령집단별 인지기능에 미치는 주효과와 상호작용효과를 검증하였다. 분석자료는 KSHAP 1차조사부터 3차조사까지 총 1,740명의 패널자료를 활용하여, 무선효과 패널로짓모형을 적용하여 분석하였다. 분석결과는 다음과 같다. 첫째, 노년기 연령증가에 따라 인지기능 저하는 급격하게 증가하는 경향성이 나타났다. 객관적 주관적 사회적 고립은 모두 80세를 변곡점으로 U자형의 분포가 나타났다. 아울러 배우자, 자녀 친척, 이웃 친구 노년기 연령증가에 따라 대체적으로 감소하는 분포가 나타났다. 둘째, 인지기능저하에 대한 주효과는 객관적 주관적 사회적 고립과 정적으로 유의미하게 나타난 반면, 대인관계갈등 유형은 유의미하게 나타나지 않았다. 셋째, 노년기 인지기능저하에 영향을 미치는 이원상호작용효과 분석결과, 주관적 사회적 고립과 인지기능저하와의 관계는 배우자와의 갈등수준별로 유의미하게 다른 것으로 나타났다. 또한 주관적 사회적 고립을 많이 느낄수록 연소노인(65~74세)에 비해 초고령노인(85세 이상)의 경우 인지기능저하가 급격하게 높아지는 것으로 나타났다. 본 연구결과에 기초하여 노년기 연령집단별 인지기능 저하를 감소시키기 위한 정책적 실천적 시사점을 제시하였으며, 연구의 한계점과 추후연구를 위한 제언에 대해 논의하였다.

본 연구는 Miller와 동료들(2009)들이 사회 정의 실천을 예측하는 이론적 틀로써 사회 인지진로 이론(SCCT)을 사회 정의 영역에 적용한 연구를 국내 대학생들을 대상으로 반복 검증한 것이다. 국내 대학생의 사회 정의에 관한 관심과 실천에 기저하는 심리적 과정을 살펴보고 사회 정의 활동을 촉진하는 개입 방안을 제안하기 위하여 서울 및 경기도 소재 4년제 대학교의 남녀 학생 337명으로 자기 보고식 설문조사를 실시하였다. 측정의 과대 추정을 막기 위해 사회적 바람직성을 통제한 상태에서 구조방정식 모형 검증을 실시한 결과, 사회 정의에 대한 자기 효능감과 결과 기대가 관심에 영향을 주고 사회 정의에 대한 관심이 실천에 영향을 준다는 연구 모형이 국내 대학생들의 사회 정의 관심과 실천을 설명하는 데 적합한 것으로 나타났다. 또한 사회적 지지와 사회적 장애가 자기 효능감을 통해 실천에 영향을 미친다는 간접 효과 모델이 사회적 지지와 사회적 장애가 실천에 직접적인 영향을 미친다는 직접 효과 모델보다 자료를 설명하는 데 더 적합한 것으로 나타났으며, 사회 정의 영역에서만 나타난 독특한 경로로 결과 기대를 통한 사회적 지지의 간접 효과가 입증되었다.

An explanatory design was employed to identify the relationship of physical, emotional & social readjustment and social support of post hospitalized stroke patients and their caregivers. A convenient sample of 254 patients who given follow-up care at the outpatient department after discharge and 225 caregivers were recruited. Mental Status Questionnaire (MSQ), Social Support Inventory Stroke Survivors (SSISS), Illness intrusiveness(II), Instument Activity of Daily Living(IADL), Center of Epidemilogic Studies-Depression(CES-D), social activity and caregiver burden were used for measurement in this study. Results showed patient's physical level measured by IADL and psychological level measured by depression were high. But social activity was low. Cognitive function, depression & social activity were not significantly different by the posthospitalized period, but IADL was. The source of professional support was mostly the physician at the outpatient department. The family support was found significantly related to patient's depression & social activity and caregiver's subjective burden. Professional support was found significantly related to patient's IADL & depression. Illness intrusiveness as a mediating variable was a sig nificantly predicting power on patient's IADL & depression. The path analysis was used to identify the variables to predict the physical, emotional, and social status of patients. As a result, patient's age, cognitive function, illness intursiveness and professional support significantly predicted the level of IADL ; patient's cognitive function, illness intrusiveness and family support significantly predicted the level of depression ; and patient's age and family support significantly predicted the level of social activity of posthospitalized stroke patients. Based upon these results, the rehabilitation programs to reduce the illness intrusiveness and improve cognitive funtion were recommended for the readjustment of the stroke patients. This model of the readjustment of the posthospitalized stroke patients is recommended as the framework for care of the stroke patients.

Objectives: This study examined how adolescents' cognitive stress relates to suicidal thought, thereby offering basic data about social and institutional ways to reduce adolescent suicide. Methods: In this study, data from an online survey on adolescents' health conducted by Korea Center for Disease Control(2013, 9th) was used after altering it to fit the purpose of the study. The data was analysed using the complex sampling method and structural equation model(SEM). Results: Whilst adolescents' cognitive stress had positive effects on suicidal thought, problem drinking and cognitive depression, it had a negative effect on physical activity. The structural equation model from cognitive stress, problem drinking, cognitive depression, physical activity influenced suicidal thought. Problem drinking on the other hand had an influence on cognitive depression. Conclusion: These findings suggest that future intervention programs for prevention of adolescents' suicidal thought should also address problem drinking, cognitive depression, and cognitive stress.

The purpose of the study was to find the sociopsychological factors predicting the intention of compliance with the dietary regimen in diabetes with a questionnaire. Data were collected from 282 adult noninsulin-dependent diabetics in Seoul, Kyoggida, and Kyongsangbukdo in Korea. Stepwise multiple regression analysis was conducted with predictor variables from theories of the Health Belief Model, Social Cognitive Model, The Theory of Reasoned Action , and Social Support. The behavioral intention of compliance with the prescribed diet was the independent variable. Subjects norm self-efficacy knowledge about diet therapy, outcome expectation, relationship with medical team, threat of deterioration of disease, and social support were the independent variables, The mean score of behavior intention was high ie 35.3 out to 42. Subjective norm and self-efficacy were the significant variables to predict the intention of dietary compliance. These variables comprised 39% of the common variance. To increase dietary compliance by influence of the referents and improve self-efficacy significant referents must be included and concrete and practical methods to follow the dietary regimen must be provided in nutrition education.

Internet has begun various transformation and innovation in terms of society, culture and industry. Today, Social Network Service(SNS) is an exceedingly popular and useful tool for making human relationships. Previous studies related to SNS, which based on Technology Acceptance Model(TAM), were focused on user acceptance of new technology. However, they had the limitations to focus on technology acceptance, without the consideration of the cognitive factors in using SNS. This study examined how the main factors of intention to use of SNS continuously affect perceived usefulness and ease of use through familiarity, self-expression, hedonic shopping value, utilitarian shopping value and personal relationship. The results of hypothesis testing showed that familiarity, self-expression, hedonic shopping value and personal relationship have some positive impacts on the perceived usefulness and ease of use. The practical contribution of this study is to suggest useful decision alternatives concerned to marketing strategies for acquiring and retaining long-term customers related to SNS business.

This study investigates the antecedents of knowledge sharing behavior focusing on the individual level factors in an assumption that the behavior is initiated from the individual level decisions. A hypothesis that the relation between personality trait and behavior is mediated by the social-cognitive constructs contained in the Theory of Planned Behavior(TPB) is tested. For the study, we suggest a TPB extended model that extends original TPB model by including conscientiousness facet of FFM(Five Factor Model). This study uses a cross-sectional design. Data were collected from a self-reported survey on 197 nurses in a tertiary hospital. The results showes a significant positive relationship between the conscientiousness facet of FFM and knowledge sharing behavior. In the TPB extended model, the conscientiousness facet has significant direct effects on all the constructs of original TPB model. Of the TPB exogenous constructs, the social norm construct alone has a significant effect on intention and the perceived behavioral has a direct significant effect on the knowledge sharing behavior. These results confirm the importance of conscientiousness in predicting knowledge sharing behavior and clarify the characteristics of knowledge sharing behavior as a contextual, job oriented behavior in a workplace. We conclude that personality trait as conceptualized in the FFM needs to be integrated into TPB model in explaining the knowledge sharing behavior. Based on these results theoretical and practical implications are discussed.

Business environment is shifting from industrial economy to knowledge based economy. Enterprises go through numerous trials for successful management in changing environment. Along with trial tests, research area has been growing simultaneously. Unlike initial research which focused on basic concepts such as: form of business model and success points. Current research emphasizes on actualization of business that enterprises plan, which brought academic research with perplex form of knowledge structure. On the other hand, there is limitation in understanding business model systematically due to preceding research primarily centered on analyzing definition and case study. In order to analyze knowledge structure, this study utilized social network analysis based on "relationship". For the analysis, 13,412 keywords were extracted from 36years worth of article or research related to business model stored in SCOPUS database. From the analysis, it was shown core research subject was INNOVATION and the number of co-authors has increased due to the academic diversity. Business model research is divided into five sub-categories (E-commerce, SMEs, sustainability, open-source, and e-book). Through cognitive map analysis on each of research characteristics of sub-category, it has shown that E-commerce, SMEs, sustainability, and open-source are core categories.

Wireless multicast is considered as an effective transmission mode for the future mobile social contact services supported by Long Time Evolution (LTE). Though wireless multicast has an excellent resource efficiency, its performance suffers deterioration from the channel condition and wireless resource availability. Cognitive Radio (CR) and Device to Device (D2D) are two solutions to provide potential resource. However, resource allocation for cognitive wireless multicast based on D2D is still a great challenge for LTE social networks. In this paper, a joint sub-carriers and power allocation model based on D2D for general cognitive radio multicast (CR-D2D-MC) is proposed for Orthogonal Frequency-Division Multiplexing (OFDM) LTE systems. By opportunistically accessing the licensed spectrum, the maximized capacity for multiple cognitive multicast groups is achieved with the condition of the general scenario of imperfect spectrum sensing, the constrains of interference to primary users (PUs) and an upper-bound power of secondary users (SUs) acting as multicast source nodes. Furthermore, the fairness for multicast groups or unicast terminals is guaranteed by setting a lower-bound number of the subcarriers allocated to cognitive multicast groups. Lagrange duality algorithm is adopted to obtain the optimal solution to the proposed CR-D2D-MC model. The simulation results show that the proposed algorithm improves the performance of cognitive multicast groups and achieves a good balance between capacity and fairness.
