  • The objective of the study is to investigate the influence of aesthetic attributes on user interface design. Theories of aesthetics are first studied from which aesthetic attributes are defined as information sources. Representation of a product is viewed as a combination of aesthetic attributes, based on a hypothesis that each attribute has a certain influence on the performance in terms of user interface. An experiment was conducted to support the hypothesis. Various combinations of aesthetic attributes of a microwave oven were generated from the orthogonal array of a conjoint analysis. Subjects perfomed on a computer two types of tasks, each of which simulated a combination of attributes. Reaction time was evaluated as a performance measure for the conjoint analysis to find out how much influence each attribute has on the performance. A computer program, UISA(User interface Simulation system of Aesthetic attributes0, was developed and used for simulation. Findings on the influences of aesthetic attributes were summarized.

  • Purpose - This study empirically analyzed the effect of the customer orientation in Insurance Salespersons on the perceived referral risk and referral intention. In the empirical study, we try to provide suggestions for reducing the perceived referral risk of customer oriented selling activities and improving the referral intentions according to customers' tendencies. Research design, data, and methodology - Data collection was conducted through the convenience sampling method for customers who had insurance coverage for about two months from March to May 2015. A total of 700 copies were distributed and 670 copies (95.7% recovery) were collected. Finally, 661 copies were used for final analysis. With the IBM PASW 22.0 statistical program. The interaction effect for the hypothesis test was generated by multiplying the average centralized independent variable and the control variable, and the average centralization variable was used to minimize the multi-collinearity problem of the interaction effect between the independent variable and the control variables. Results - Hypothesis 1 was adopted because the effect of customer-oriented selling activities on perceived referral risk were significantly negative. The effect of customer orientation on perceived referral risk is affected by innovative tendency, risk-taking tendency, and interpersonal tendency Interaction effect was observed. Therefore, Hypothesis 2-2, Hypothesis 2-3, Hypothesis 2-4 were adopted. The effect of customer-oriented selling activities on referral intention was significantly positive, and Hypothesis 3 was adopted. The effect of customer orientation was influenced by the interaction effect of innovative tendency. Therefore, only Hypothesis 4-2 was adopted. Finally, the effect of perceived referral risk on referral intention was significantly negative and hypothesis 5 was adopted. Conclusions - This study suggests that it is important for the salespeople to grasp the customers' propensity in consideration of the perceived referral risk and referral intention according to the moderating effect of customer orientation. In this study, we showed that customer-oriented selling activities positively influence referral intention by inducing perceived referral risk in customers with stronger risk-taking tendencies. It is thought that it will be an important basic data in designing a customer's selling strategy or conducting selling activities.

  • 최근의 보고에 따르면 우리 나라 학생들은 학년이 높아질수록 과학적 수준은 반대로 떨어지는 경향을 보이고 있지만 고등학교 이후 집단의 과학적 추론능력에 대한 연구는 체계적으로 이루어지지 않고 있다. 특히 가설검정능력과 관련된 과학적 추론은 가장 고등한 인지기능의 하나로 여겨지고 있고, 또 창의적이고 비판적인 사고에 매우 중요하다고 보고되어 왔다. 따라서 본 연구는 우리나라 대학생들의 과학적 추론 능력을 조사하고, 이를 미국 대학생들의 과학적 추론 능력과 비교하여 분석하였다. 아울러 본 연구는 가설 검정능력이 과학적 추론능력의 다른 하위요소에 비해 고등한 추론기능이라는 가설도 검정하였다. 고등학교 이후의 과학적 추론에 대한 경향을 조사하기 위하여 본 연구는 한국의 대학생 774명과 미국의 대학생 568명에게 과학적 추론 검사를 실시하여서 비교 분석하였고, 이 자료를 토대로 가설검정능력이 과학적 추론의 다른 하위요소에 비해 고등한 추론이라는 가설도 검정하였다. 본 연구에 사용된 과학적 추론 검사는 보존논리, 비례논리, 변인통제, 확률논리, 상관논리, 그리고 가설검정기능에 관련된 127개의 과제로 구성되어 있다. 본 연구의 결과는 한국 대학생들이 비례 및 확률논리를 평가하는 과제에 대해서는 미국 학생들보다 월등하게 높은 접수를 기록하였고, 보존이나 변인통제, 그리고 상관논리를 평가하는 과제에 대해서는 반대의 경향을 나타내었다. 또한 가설검정 능력을 평가하는 문항에서는 양국 모두 다른 과학적 추론 과제에 비해서 뚜렷하게 낮은 점수를 보여주었다. 본 연구는 이들 결과에 대해서 본 연구의 목적과 관련해서 논의하였고 이의 교육적 적용에 대해서도 논의하였다.
