Various contexts are involved in the processes of science learning and instruction. In the perspective that the results of science learning and instruction usually depend on the nature of learning task content and context, content effects or context effects have been researched up to now. But, the discrimination between them was very ambiguous. For the clarity of them, it was supposed that science content would be composed of decontextualized knowledges and contexts, which were respectively dichotomized in common and special ones among disciplines of science. Science learning and instruction was discussed in view of interactions between cognitive, learning task, and social-cultural contexts. Especially, it was emphasized that task contexts, as a bridging role among contexts should be constructed considering cognitive and social cultural contexts.

Pervasive computing and social network are good resources in recommendation method. Collaborative filtering is one of the most popular recommendation methods, but it has some limitations such as rating sparsity. Moreover, it does not consider social network in pervasive computing environment. We propose an effective proactive friend recommendation method using social network and contexts in pervasive computing environment. In collaborative filtering method, users need to rate sufficient number of items. However, many users don't rate items sufficiently, because the rating information must be manually input into system. We solve the rating sparsity problem in the collaboration filtering method by using contexts. Our method considers both a static and a dynamic friendship using contexts and social network. It makes more effective recommendation. This paper describes a new friend recommendation method and then presents a music friend scenario. Our work will help e-commerce recommendation system using collaborative filtering and friend recommendation applications in social network services.

Incidental envy is known to motivate self-improvement behavior. This phenomenon occurs in part because feelings of inferiority guide subsequent behavior in a way to self-improve, after experiencing envy. However, no research has yet examined whether this tendency may be affected by social context: private versus public. Although extant literature suggests that envy generally leads to self-improvement, we demonstrate that this effect may be mitigated under public social contexts. Across two studies, we find that although incidental envy generally increases self-improvement behavior (e.g., effort exertion and charitable giving) in private social contexts, this tendency is attenuated under public social contexts. We conclude with a discussion of theoretical and practical implications of this finding.

This study was accomplished to present a new paradigm of rural environmental planning for the purpose of changing a rural planner's acknowledgments. This study was composed of a follows, To search the structures and orders in rural environment on the point of four environmental contexts. First, environment contexts with spaces, society, and time. Second, environment contexts with spaces unit in human settlement. Third, environment contexts with correlation of physical environment, institutional environment, and social environment. Fourth, environment contexts with ecotope( physiotope + biotope) and landscape ecology. To analyze and criticize a present political situation of rural planning in Korea. To apply a paradigm of environmental planning for rural planning.

A Product-Service Systems (PSS) is composed of service and product element to provide values for relevant stakeholders. A typical service interaction involves providers and receivers, and respective values are provided in a social interaction. In cases, more than one providers are interacting with a receiver. In others, service interaction is happening in a public manner where social issues amang peer receivers are important. When service channel is supported by physical touchpoints, receivers would interact with products, which may interact with providers. Thus, in PSS, a various kinds of interactions occur in diverse social contexts. A simple representation method for social contexts is introduced where service providers, receivers and products are represented as nodes and interaction between them are represented as directed edges. Social context of several PSS examples are described with this. In booth designing and operating PSS, social context representations could be used in analyzing and comparing key aspects of social interaction types to retrieve similar cases to exploit related interaction design strategies and operation know-hows.

본 연구는 여러 정서표현의 길이가 놀이 행동과 비놀이 행동에 있어서 유의미한 차이가 있는지, 또한 정서표현과 관련된 놀이의 인지적, 사회적 맥락은 무엇인지를 살펴봄으로써 놀이의 정의적 국면으로 간주되어야할 정서적 특정과 그 맥락적 특정을 밝히고자 하였다. 아동의 놀이 행동에 있어 가장 지배적으로 나타나는 정서는 흥미였으나, 비놀이 행동에서와 비교하여 놀이 행동에서는 오히려 흥미와 분노 표현이 유의미하게 짧게 관찰되었고, 유일하게 기쁨만이 비놀이 행동에서보다 놀이 행동에서 유의미하게 오래 표현되었으며 이러한 현상은 나이와 성에 관계없이 일관되게 나타났다. 또한 흥미 정서의 표현은 구성놀이에서와 단독, 병렬놀이 등에서, 기쁨 정서의 표현은 격투놀이와 연합, 협동 놀이 등에서 유의미하게 오래 관찰되었다. 본 연구 결과는 놀이의 정의에 있어 즐거움이라는 정서적 특성에 대한 경험적 증거로서의 의의와 놀이에서의 기쁨의 표현에 대한 맥락적 해석을 중심으로 논의되었다.

Social media marketing has gained attention from marketers because of the growing number of social media users. Considering the unique context of each company or organization behind the marketing is necessary when choosing and applying various social media marketing strategies to ensure achievement of better business performance. However, previous studies have focused on context-specific marketing strategies. Accordingly, this study aims to develop context-specific social media marketing strategies. In this study, we first develop a conceptual framework with two items, namely, brand awareness and business orientation of an organization, as criteria, and classify the framework into four contexts. We then propose context-specific social media marketing strategies for each of the contexts. We examine the framework and proposed social media marketing strategies based on multiple case studies. The primary contribution of this study is our context-specific social media marketing strategies.

본 연구는 3~6세의 언어장애아동을 대상으로 일상적 스크립트를 활용한 언어중재에서 양육자와 언어재활사가 인식하는 우선적 중재가 필요한 주요 의사소통 상황을 분석하는데 목적이 있었다. 예비조사와 본 설문조사를 거쳐 수집한 데이터를 계층분석 (AHP)을 사용하여 분석하였다. 그 결과, 3개의 상위 상황 중에서 양육자는 '교육사회생활' 그리고 언어재활사는 '가정생활'을 가장 우선적인 상황으로 선택하였다. 상위별 하위상황의 경우, '가정생활'에서는 '식사', '교육사회생활'에서는 '친구와 놀기'가, 그리고 '여가문화생활'에서는 '놀이터'가 중요한 의사소통 상황으로 인식되었다. 전체 35개의 하위 상황에서 양육자는 '친구와 놀기' 그리고 언어재활사는 '식사'를 선택하였으며, 상위 5순위의 상황을 살펴보면 양육자와 언어재활사 모두 '가정생활'의 상황들이 높은 중요도 비율을 보였다. 아동연령별로 양육자 인식을 분석한 결과, 3세와 6세의 각 양육자 집단은 '가정생활' 그리고 4세와 5세의 각 양육자 집단은 '교육사회생활'을 가장 중요한 상위 상황으로 보았다. 전체 하위상황에서도 아동의 연령별로 양육자의 주요 상황에 대한 우선순위 인식에서 약간의 차이를 보였다. 본 연구결과는 언어재활사가 스크립트를 활용한 언어중재를 실시할 때 아동의 연령과 발달수준 뿐만 아니라 양육자의 요구를 고려한 의사소통 상황의 선정이 필요함을 시사한다.

This study analyzes the epistemological meaning of‘social construction’in mathematical instruction. The perspective that consider the cognition of mathematical concept as a social construction is explained by a cyclic scheme of an academic context and a school context. Both of the contexts require a public procedure, social conversation. However, there is a considerable difference that in the academic context it is Lakatos' ‘logic of mathematical discovery’In the school context, it is Vygotsky's‘instructional and learning interaction’. In the situation of mathematics education, the‘society’which has an influence on learner's cognition does not only mean‘collective members’, but‘form of life’which is constituted by the activity with purposes, language, discourse, etc. Teachers have to play a central role that guide and coordinate the educational process involving interactions with learners in this context. We can get useful suggestions to mathematics education through this consideration of the social contexts and levels to form didactical situations of mathematics.

이 논문에서는 지리적 표현이 보강된 사회네트워크 모형을 제시하고, 이 모형을 통해 사회네트워크의 지리적 맥락을 시각화하는 3D 웹서비스를 구현한다. 이 연구에서 제안하는 사회네트워크 그래프 개선의 핵심요소는 (i) 네트워크 노드들의 상호작용 강도 및 공간적 인접성이 반영된 '지리적 가중치가 부여된 중심화 지수' 그리고 (ii) 이러한 중심화 지수를 3차원 심볼을 이용하여 표현함과 동시에 네트워크 노드들을 단계 구분도와 중첩하여 시각화하는 '지도와 결합된 사회네트워크 그래프'이다 개선된 사회네트워크 그래프는 X3D (Extensible 3D)를 이용하여 구현하였으며, 시도간 R&D 협력의 사례분석을 통해 그 적용가능성이 확인되었다. 이 논문에서 제시하는 방법론은 사회네트워크에 내재하는 공간적 집중화의 경향 등 기존의 네트워크 분석에서 간과되었던 사회네트워크의 지리적 맥락에 대한 시각적 단서를 제공한다.
