  • 본 연구에서는 디스커버리가 제공하고 있는 다양한 기능들에 대해 평가요소를 선정하여 그 상대적 중요성을 분석하였다. 먼저, 선행연구를 통해 선정된 다양한 평가항목들에 대해 콘텐츠, 탐색기능, 우연한 발견, 상호작용성, 사용의 편리성 등 다섯 개 카테고리로 구분하고 이들을 다시 36개의 세부 평가항목으로 구성하였다. 각 평가요소들의 상대적 중요성을 객관적으로 평가하기 위해서 AHP 기법을 채택하였다. 평가결과 상위 항목에서는 사용의 편리성이 가장 중요하고 이어서 콘텐츠, 탐색기능, 상호작용성, 우연한 발견 순으로 나타났다. 또한 전체 36개의 하위 평가항목에 대한 중요도 분석결과 콘텐츠 통합데이터 품질이 가장 중요한 요소로 나타났다. 이러한 연구결과는 추후 디스커버리를 도입하거나 선정하기 위한 기초자료로 활용할 수 있을 것으로 기대한다.

  • This study aims to determine and analyze the effect of social shopping, adventure shopping, value shopping, relaxation shopping, and idea shopping in influencing impulsive online buying behavior moderated by scarcity and serendipity information. The research method used is the quantitative research paradigm using surveys as a medium to obtain primary data. The paper examines the theoretical research model and tested fifteen hypotheses. The questionnaire was developed based on indicators from previous research. A non-probability sampling framework is used in this study. The data collection method uses electronic and online questionnaires to collect primary data with a total sample of 330 taken with the criteria of having made transactions in e-commerce Shopee in the last three months. Data analysis tools using Structural Equation Modelling (SEM) approach. The results showed that 8 out of 15 hypotheses were accepted and supported. The results show that there is a relationship between the value of hedonic shopping, scarcity, and serendipity information on impulsive online buying behavior. Therefore, analyzing the needs of customers, optimizing customer satisfaction, service excellence, website quality, and the ease of use of e-shopping itself especially in the e-commerce industry should be taken seriously nowadays.

  • 제품이나 서비스에서 사용자가 예상하지 못한 의외성을 제공할 때 사용자는 만족을 넘어 감동할 수 있으며, 최근 몇몇 애플리케이션이나 웹서비스는 이러한 의외성을 제공하고 있다. 그러나 의외성 자체는 오히려 사용 용이성을 떨어뜨리는 등 문제를 야기 시킬 수 있음에도, 기존 모바일 애플리케이션 관련 연구들은 주로 사용성 중심의 만족을 다루었다. 따라서 본 연구에서는 이러한 의외성으로 인한 사용자 경험의 변화를 세렌디피티(뜻밖의 발견으로부터 유발되는 예상치 못한 즐거움) 개념을 이용하여 모바일 애플리케이션의 UX 분야에서 실험적으로 확인하고, 이로부터 유발되는 요인이 사용자 만족에 미치는 영향에 대해 관찰했다. 즉, 모바일 애플리케이션의 인터랙션을 통해 유발시킨 의외성과 동시에 게임 요소를 제공한 세렌디피티, 지각된 신규성과 지각된 사용 용이성, 지각된 유용성, 그리고 만족 등의 요인들 간 관계를 살펴봤다. 그 결과 세렌디피티가 지각된 신규성에 정(+)의, 사용 용이성에 부(-)의 영향을 미치고, 지각된 신규성과 지각된 사용 용이성이 지각된 유용성에 정(+)의 영향을 미치며, 세 가지 요인 모두 사용자 만족에 정(+)의 영향을 미치는 것이 관찰됐다.

  • In this paper we deal with the numerical solution of the Reissner-Mindlin plate problem with the use of high order finite elements. In previous papers we have solved the problem using approximation spaces of Serendipity type, in order to minimize the number of internal degrees of freedom. Since further numerical experiences have evidenced that the addition of bubble functions improved the quality of the results we have modified the previous family of hierarchic finite elements, adding internal degrees of freedom, to make a systematic analysis of their performance. Of course, more degrees of freedom are introduced. Nonetheless the numerical results indicate that the reduction of the error outnumbers the increase of degrees of freedom and therefore bubble plus elements are preferable.

  • A new 8-node serendipity quadrilateral plate bending element (MQP8) based on the Mindlin-Reissner theory for the analysis of thin and moderately thick plate bending problems using Integrated Force Method is presented in this paper. The performance of this new element (MQP8) is studied for accuracy and convergence by analyzing many standard benchmark plate bending problems. This new element MQP8 performs excellent in both thin and moderately thick plate bending situations. And also this element is free from spurious/zero energy modes and free from shear locking problem.

  • A three dimensional finite element generation code has been developed attaching simple blocks. Block can be either a quadrature or a cube depending on the dimension of a subject considered. Finite element serendipity basis functions are employed to map elements between the computational domain and the physical domain. Elements can be generated with wser defined progressive ratio for each block. For blocks to be connected properly, a block should have a consistent numbering scheme for vertices, side nodes, edges and surfaces. In addition the edge information such as the number of elements and the progressive ratio for each direction should also be checked for interfaces to have unique node numbers. Having done so, user can add blocks with little worry about the orientation of blocks, Since the present the present code has been written by a Visual Basic language, it can be developed easily for a user interactive manner under a Windows environment.

  • This paper is an extension of previous study[1] on a development of a divergence-free element method using a hermite interpolated stream function. Divergence-free velocity bases defined on rectangles derived herein produce pointwise divergence-free flow fields. Hence the explicit imposition of continuity constraint is not necessary and the Galerkin finite element formulation for velocities does not involve the pressure. The divergence-free element of the previous study employed hermite (serendipity) cubic for interpolation of stream function, and it has been noted a possible discontinuity in variables along element interfaces. This deficiency can be removed by use of a hermite bicubic interpolated stream function, which requires four degrees-of-freedom at each element corners. Those degrees-of-freedom are the unknown variable, its x- and y-derivatives and its cross derivative. Detailed derivations are presented for both solenoidal and irrotational basis functions from the hermite bicubic interpolated stream function. Numerical tests are performed on the lid-driven cavity flow, and results are compared with those from hermite serendipity cubics and a stabilized finite element method by Illinca et al[2].
