Due to the intense competition and low switching cost, to find out which factors will significantly impact on user's continuance intention is very important for mobile instant messaging (IM) practitioners. In this study, we adopted network externalities and perceived service quality as independent variables based on the definition of mobile IM service. Network externalities also include direct externalities (referent network size) and indirect externalities (perceived complementarity). The result of this study shows that referent network size has a critical influence on perceived usefulness and perceived complementarity has a critical influence on perceived enjoyment; perceived service quality, as we expected, has significantly impact on not only customer's satisfaction but also perceived usefulness and perceived enjoyment. Meanwhile, both perceived usefulness and perceived enjoyment have directly critical influences on customer's continuance intention.

현재 뇌에 대한 연구는 지속적으로 연구되고 있는 분야 중에 하나이다. 뇌파나 뇌의 활동들을 분석할 수 있는 장비들이 개발되면서 더욱 활발하게 연구되어지고 있다. 기중 뇌의 기능에 대한 연구들도 화발하게 연구되고 있는 분야 중에 하나이다. 뇌의 기능은 보고, 듣고, 말하고, 생각하는 등의 모든 행위들과 연관되어있다. 또한 그러한 기능들은 인지능력이라고 하기도 한다. 인지능력은 인지적, 정신적인 요구가 필요하다. 이러한 것을 인지부하라고 하고, 과도한 인지적, 정신적인 요구는 인지과부하라고 한다. 인지부하에 따라서 인지능력은 영향을 받는다고 할 수 있다. 본 연구에서는 인지부하에 따라서 인지능력이 변화하는 정도를 실험하였다.

Using Technology Acceptance Model and flow theory as our foundation, this paper investigates the interrelationships among social influence, individual cognition, flow, and actual usage in the Web 2.0 environment. According to TAM, users evaluate perceived usefulness(PU) and ease of use(PEU) of information technology(IT) in accepting the innovative IT. Along with users' cognitive evaluation(i.e. PU and PEU), in case of UCC(user-created-contents), which is one of the representative Web 2.0 features, flow also has a significant effect on users' usage. Accordingly, the current study involve cognitive elements such as PU and PEU as well as flow of enjoyable state during using IT in exploring antecedents leading to UCC usage. On one hand, we consider the effect of social influence on users' cognition and flow toward actual usage because the more users creates Web contents, the more long-tail situation prevails on the Internet. Web 2.0 becomes a kind of social phenomena. The empirical results show that social influence affects positively both PU/PEU and flow. Users' cognitive evaluation and flow have positive impacts on users' UCC usage.

This study analyzed the effect of the cognitive style of field dependence/independence to the information-seeking behaviors of 250 undergraduate students. The cognitive style of field dependence/ independence was examined by Group Embedded Figure Test (GEFT), information-seeking behaviors were examined by information-seeking performances, and survey for information-seeking behaviors. As a result of the analysis, the cognitive style of field dependence/independence affected items of information-seeking performances except one item among items set in this study. The cognitive style, the cognitive characteristics acting in the process of cognitive activity affected the actual activities of information-seeking behaviors. The cognitive style of field dependence/independence affected the seeking process except the results of seeking and general information-seeking behaviors in the areas of information-seeking behaviors. Therefore, the study of cognitive style can be effective in the seeking process areas of information-seeking behaviors.

The purpose of this study is to examine the causal relationships among self-efficacy, perceived usefulness, perceived ease of use, perceived playfulness, and reuse intention of SNS. The results of data analysis by structured equation model(SEM) indicate that self-efficacy significantly influences individual's perceived ease of use, perceived usefulness and perceived playfulness. Both perceived playfulness and perceived ease of use affects perceived usefulness on SNS. Individual's self-efficacy, perceived playfulness and perceived usefulness affect reuse intention of SNS. Based on the results, the theoretical and practical implications of this study are discussed.

본 연구는 무리행동과 인지적 유용성을 중심으로, e-learning 컨텐츠 구매에 미치는 영향을 e-learning 수강경험자 집단과 경험하지 못한 잠재구매자 집단의 차이점을 경험적인 측면에서 밝히고자 시도하였다. 전체 528명의 표본을 경험자(395명)와 비경험자(133명)로 나누어 PLS(Partial Least Square)를 통하여 분석한 결과 e-learning 구매 경험자는 인지적 유용성이 구매의도에 주는 영향이 무리행동의 영향보다 큰 것으로 나타났고, 잠재 구매자는 무리행동이 구매의도에 주는 영향이 더 큰 것으로 나타났다.

최근 고령화로 인한 수명연장은 노후생활비용 부담의 가중을 통해 고령자들의 노후파산 가능성을 높이는 핵심 위협요인이 되고 있기 때문에 이를 위한 사적자산의 안정적, 장기적인 관리와 증식이 필수적이다. 자산관리 자문/일임 서비스를 이용하는 것은 이를 해결할 수 있는 좋은 대안이지만 과거에는 서비스 이용가능 대상이 대형 금융기관을 거래하는 거액자산가들로 국한되어 있었다. 그런데 최근 기술혁신과 더불어 플랫폼을 기반으로 하는 웰스테크(디지털 자산관리) 서비스가 빠른 속도로 대중화되고 있어, 이를 활용하면 보다 많은 고령자들이 자산관리에 대한 부담을 경감할 수 있을 것으로 예상된다. 본 연구에서는 이런 이유로 최근 주목받는 웰스테크(디지털 자산관리) 자문/일임 서비스에 대한 고령자들의 사용의도에 영향을 미치는 특성 및 요인들을 파악하고자 한다. 이를 위해 기술수용이론 중 소비자가 얻는 혜택과 희생을 모두 고려하는 '가치기반수용모델(Value Based Model)'을 기본 모형으로 하되 웰스테크(디지털 자산관리) 자문/일임서비스의 특성을 고려하여 '가격효용성'을 혜택 요인에 추가하였다. 또한 고령자의 특성을 고려하여 희생 요인에 '인지된 위험'을, 별도의 요인으로 '사회적 영향'을 각각 추가하였다. 예상되는 연구결과로는 지각된 혜택에 해당하는 유용성, 즐거움, 가격효용성은 모두 인지된 가치에 유의한 (+)의 영향을 미칠 것으로 예상되는 반면, 지각된 희생에 해당하는 기술성과 인지된 위험은 모두 인지된 가치에 유의한 (-)의 영향을 미칠 것으로 예상된다. 또한 추가변수인 사회적 영향은 인지된 가치에 유의한 (+)의 영향을 미칠 것으로 예상된다.

The purpose of this study is to offer the implication for elementary school mathematics teaching by analyzing teachers' reflection on the cognitive demands of mathematical tasks they give in class. During the setup phase and the implementation phase in math class, the researchers analyzed the change of cognitive demands on mathematical tasks and the factors which had influence on such changes. After teachers' reflection on teaching, the researchers analyzed the change of cognitive demands on mathematical tasks and the factors which had influence on such changes in math classes. As a result, before teachers' reflection on the cognitive demands of mathematical tasks, the higher-level demands of mathematical tasks had a tendency to decline. However, after teachers' reflection on the cognitive demands of mathematical tasks, higher-level demands of mathematical tasks were maintained.
