Cooperative spectrum sensing has been considered as a promising approach to improve the sensing performance in distributed cognitive radio networks. However, there may exist some selfish secondary users (SUs) who are unwilling to cooperate. The presence of selfish SUs could cause catastrophic damage to the performance of cooperative spectrum sensing. Following the social perspective, we propose a Social Tie-based Incentive Scheme (STIS) to deal with the selfish problem for cooperative spectrum sensing in distributed cognitive radio networks. This scheme inspires SUs to contribute sensing information for the SUs who have social tie but not others, and such willingness varies with the strength of social tie value. The evaluation of each SU's social tie derives from its contribution for others. Finally, simulation results validate the effectiveness of the proposed scheme.

본 연구는 비영리 사회복지조직 구성원의 사회적기업가정신이 협조적행동에 미치는 영향력을 살펴보았으며 이들의 관계에서 가치일치의 매개효과를 검증하였다. 전국 사회복지기관에 종사하는 구성원을 대상으로 검증한 결과, 첫째, 사회적기업가정신의 구성요소 중 혁신성, 위험감수성, 사회적가치지향성이 유효하며 둘째, 사회적기업가정신의 혁신추구성향과 사회적가치지향성이 영향을 주며 위험감수과정에서는 협조적행동에 영향을 주지 않았다. 셋째, 구성원의 가치일치가 협조적행동에 긍정적인 영향을 미쳤으며 넷째, 사회적기업가정신과 협조적행동 간에 가치일치가 부분매개하는 것으로 나타났다. 이는 사회적기업가정신이 높을수록 가치일치가 높아지고 이를 통해 협조적행동이 높아진다고 할 수 있다. 또한 조직구성원들의 협조적행동을 강화시키기 위해서 가치일치가 중요하며 사회적기업가정신을 갖춘 직원을 채용하거나 직원교육을 강화하는 노력이 필요하다는 것을 알게 되었다는 점에서 의의를 갖는다.

과학영재학교의 교육과정 운영과 교과지도 방법에 협력교수가 중요한 개념으로 등장하게 되었다. 본 연구에서는 협력교수의 관점에서 과학영재학교의 교육과정 운영을 살펴보고, 사회과의 교수-학습과정에 적용할 수 있는 협력교수 방안과 실현 가능성을 탐색하였다. 이에 본 연구에서 살펴본 것과 그 결과는 다음과 같다. 첫째, 협력교수의 개념을 정리하고 여러 교육현장에서 이 개념에 근거한 방법적 적용들이 어떠한가를 살펴보았다. 둘째, 협력교수의 관점에서 현재 과학영재학교에서 이루어지고 있는 전 교과의 교수-학습을 살펴보았다. 셋째, 현재의 교육과정과 주어진 여러 물리적.인적 여건을 고려하여 사회과의 협력교수 방안을 탐색하였다. 넷째, 협력교수의 한 방안으로 제시된 '세미나 수업'의 일부분을 시행하였다. 세미나의 대주제는 시사성이 있는 통합적 주제로 '중국의 고구려사 왜곡 문제'였으며, 지리, 역사, 일반사회, 윤리 및 사상을 담당하는 교사와 희망한 학생들이 영역별 소주제를 중심으로 연구와 협력학습이 진행되었다. 다섯째, 세미나 준비와 발표등의 과정에서 교사-교사, 학생-학생, 교사-학생의 상호작용이 활발하게 있었고, 특히 교사들 간의 상호작용은 협력교수로 발전할 수 있는 가능성을 찾게 되었다. 마지막으로, 학생들은 사회과 학습에 적극적으로 참여하려는 공감대를 형성할 수 있었고, 사회현상에 대해 연구하는 방법을 익히고 동시에 사회현상을 다각적인 관점에서 접근할 수 있는 안목을 넓히게 되었다.

This study was aimed to at examining whether the effects of cooperative learning on children's social competence and self-esteem would be different in terms of young children's intellectual ability. To this end, a total of 64 five-year-old children attending two kindergartens in Kyunggi-Do were selected to participated in this study. Each child was tested on the short form of K-WPPSI and fell into one of two levels (high or low). The children in the experimental group took part in thirty-five 30~40 minute sessions of cooperative learning, while the control group engaged in individual learning. The results were as follows : First, children who participated in cooperative learning achieved higher improvements in social competence and self-esteem than children engaged solely in individual learning. Second, there were no any significant differences in improvement in terms of social competence and self-esteem between the high and the low intelligence levels. On the basis of these results, it could be concluded that cooperative learning had a number positive effects upon the levels of young children's social competence and self-esteem.

Recently, the educational community has attempted to implement the theory of multiple intelligences. In approaching multiple intelligences, teachers have applied the same structural approach which has been so successful with cooperative learning. Cooperative learning is easy to learn and implement, fun for teachers and students, and produce profoundly positive outcomes along a remarkable number of dimensions. Different structures are designed for different outcomes, including enhanced mastery of subject matter, improved thinking skills, team building, class building, development of social character and social skills, communication skills, classroom management, classroom discipline, and development of and engagement of each of the multiple intelligences. Cooperative learning is becoming an increasingly popular teaching strategy. In this study, it is aimed to clarify the application of cooperative learning in health education. Cooperative Learning in health education enhances student learning by: 1) providing a shared cognitive set of information between students, 2) motivating students to learn the material, 3) ensuring that students construct their own health knowledge, 4) providing formative feedback, 5) developing social and health group skills necessary for success outside the classroom, and 6) promoting positive interaction between members of different cultural and socio-economic groups. Cooperative Learning structures and techniques in health education are following. Flash Card, Focused Listing, Structured Problem-solving, Paired Annotations, Structured Learning Team Group Roles, Send-A-Problem, Value Line, Uncommon Commonalities, Team Expectations, Double Entry Journal, Guided Reciprocal Peer Questioning, What if. Because the purpose of health education is the practice, therefore health specialists have to guide powerful and effective teaching method The application of cooperative learning in health education may improve its effectiveness.

정보통신기술의 발달로 인하여 스마트 기기와 앱, SNS, 미러링 등을 이용한 의사소통이 이루어지고 있으며 이러한 사회의 변화를 반영하여 최근 다양한 협업 상호작용을 강조한 스마트교육이 대두되고 있다. 이에 본 연구에서는 초등학생의 의사소통능력을 신장시키기 위해 스마트교육과 LT 협동학습 모형을 연계한 '스마트 기반 협동학습' 모형을 개발하여 초등학교 3학년 사회과 수업에서 적용하고 스마트 기반 협동학습과 일반적인 협동학습이 의사소통능력에 미치는 영향을 각각 비교, 분석하였다. 그 결과, 일반적인 협동학습 모형을 적용한 수업의 초등학생들보다 스마트 기반 협동학습을 적용한 사회과 수업에서 초등학생들의 표현, 경청과 이해, 상호작용 등 의사소통능력의 모든 하위 영역이 신장되었다. 이는 스마트 기반 협동학습이 학습자의 생각이나 의견을 말과 글로 명료하게 표현하게 하고, 다른 학생들의 말과 글의 의미를 파악할 수 있게 해 주며 사회적 상황에서 목적에 맞게 상호작용하는 능력을 향상시켜 준다고 할 수 있다.

Purpose: This study was to examine whether a health care model that provides comprehensive medical services based on population groups to members of the medical cooperative is applicable as a policy alternative in terms of medical use and cost. Methods: Data were derived from National Health Insurance claim data in 2019. We compared the medical volume and expenses of patients who visited social cooperative-type medical clinics with other patients, control group who visited other clinics in a local area. Results: The average number of visit days was 25.3 days in social cooperative-type medical clinics, more than 24.2 days in the control group (p=.004). However, the average medical cost per visit was KRW 46 thousand in social cooperative-type medical clinics, which was significantly lower than KRW 51 thousand in the control group (p<.001), and the total medical cost was also KRW 16.1 billion in social cooperative-type medical clinics and KRW 16.9 billion in the control group. Conclusion: We identified that a population-based health care model might change patients' behaviors to health care services and decrease total medical cost. Further population based experiment is needed to develop alternative healthcare model.
