현재 게임 산업의 규모는 급성장하며 주목받는 산업으로 자리 잡고 있다. 따라서 게임 분야에 대한 체계적인 사용자 경험 디자인의 중요성 또한 높아지고 있다. 본 연구에서는 상대적으로 사용자 유입과 유출이 빈번한 온라인 게임에서 사용자 접근과 유지를 위한 진입 과정에 대한 분석을 수행하여, 진입 과정의 개선 방향성을 제시하고자 한다. 본 연구는 첫째, 문헌 고찰을 통해 사용자의 게임 초기 경험인 진입 과정을 발견, 학습, 몰입의 3단계로 정의하여 구분하였고, 이를 경험 디자인, 게임 디자인 요소로 분석하여 진입 과정의 단계별 영향을 미치는 UX 요소를 도출하였다. 둘째, 도출된 UX 요소를 바탕으로 게임 경험 및 인지 요소 분석 프레임을 제시하였고, 이를 통해 5가지 국내 대표 온라인 게임을 정성적으로 분석하였다. 사례분석을 통해 게임들의 진입 과정 구성과 핵심 인지 요소를 도출할 수 있었다. 결론적으로 발견 단계는 선택적 주의집중, 학습 단계에선 작업 기억과 능동적 학습, 그리고 몰입 단계는 참여와 동기가 핵심적 인지 요소로 작용하였다. 마지막으로 도출된 핵심 인지 요소를 중심으로 진입 과정의 단계별 개선 방향성을 제시하였다. 이와 같은 연구를 통해 온라인 게임에서 사용자 진입 과정의 중요성을 강조하고, 진입장벽을 낮출 수 있는 개선안을 제안하였다.

User enjoyment is a key factor to understand online and mobile game users' behaviors. This study aims to understand the differences between mobile and online games, and the differences between Korean and Chinese game users in terms of the perceived importance of user enjoyment elements. To use AHP (Analytic Hierarchical Process), we decompose user enjoyment into sub-elements; sensory enjoyment, content enjoyment, enjoyment of the achievement, and enjoyment of interaction. Though the empirical study and independent t-test, we can find that there are the differences in the perceived importance of user enjoyment elements between Korean and Chinese game players, and between mobile and online games. Chinese users more stress on enjoyment of interaction and Korean users more emphasize on enjoyment of the achievement.

Void ratios are one of the key parameters for exact calculation of settlement of soft groundse. In the study, shear wave velocities of a soft ground were used to measure the field void ratio using bender elements sensors. The bender-element probes were installed in situ at the depths of 3, 5 and 8m on a pre-loading site near Incheon, Korea. During 90 days after installation, the changes of shear wave velocity and ground surface settlement were measured. The field void ratio was estimated from measured shear wave velocities. The void ratio estimated by the shear wave velocity measured by bender elements agrees well with the measured values in the field.

The objective of this study is to suggest planning directions for rural landscape management and conservation. With wide literature review, the Rural Traditional Theme Village were selected as case study areas to search for the main elements according to various spatial types. The pictures taken from the site investigation were used for a questionnaire survey to understand and to find the value of rural landscape. Finally, we found out 25 items from 3 spatial type (rural life area, agriculture production area and natural environment area), and Analyzed the Preference of rural landscape elements.

A 3D solid element mesh generation algorithm was newly developed. 3D surface points of global rectangular coordinates were supplied by a 3D laser scanner. The algorithm is strait forward and simple but it generates mixed solid elements such as hexagonal, pyramid and prism types. Then, the surface triangular or rectangular elements were generated from the solid elements. The key of the algorithm is elimination of elements and 3D adaptive surface smoothing using given 3D surface point data.

An algorithm for the automatic generation of quadrilateral shell elements on three-dimensional sculptured surfaces has been developed, which is one of the key issues in the finite element analysis of structures with complex shapes such as automobile structures. Mesh generation on sculptured surfaces is performed in three steps. First a sculptured surface is transformed to a projection plane, on which the loops are subdivided into subloops by using the best split lines, and with the use of 6-node/8-node loop operators and a layer operator, quadrilateral finite elements are constructed on this plane. Finally, the constructed mesh is transformed back to the original sculptured surfaces. The proposed mesh generation scheme is suited for the generation of non-uniform meshes so that it can be effectively used when the desired mesh density is available. Sample meshes are presented to demonstrate the versatility of the algorithm.

Software architecture is the blueprint for a software system and should provide consistent guidelines for design, implementation, and maintenance throughout the entire lifecycle of the system. Components, interactions between the components, well-formed structure, reasons, and various perspectives reflecting various stakeholders' concerns changing through the phases of software lifecycle are the key elements of software architecture. The architect identifies and engages the stakeholders, understands and captures stakeholder's concerns including those regarding life cycle, and lets the concerns reflected in the architecture. To do so, architect should take into consideration various contextual elements regarding the system too. We make an extended list of the elements, especially those of business application software architecture, that the architect should take into consideration and construct a model of the relationships between the elements.

The paper considers aspects of the energy dissipation response of selected realistic forms of torsionally balanced and torsionally unbalanced building systems, responding to an ensemble of strong-motion earthquake records. Focus is placed on the proportion of the input seismic energy which is dissipated hysteretically, and the distribution of this energy amongst the various lateral load-resisting structural elements. Systems considered comprise those in which torsional effects are discounted in the design, and systems designed for torsion by typical code-defined procedures as incorporated in the New Zealand seismic standard. It is concluded that torsional response has a fundamentally significant influence on the energy dissipation demand of the critical edge elements, and that therefore the allocation of appropriate levels of yielding strength to these elements is a paramount design consideration. Finally, it is suggested that energy-based response parameters be developed in order to assist evaluations of the effectiveness of code torsional provisions in controlling damage to key structural elements in severe earthquakes.

Photosensitive amorphous materials are attractive for the formation of several optical elements by a specific laser beam irradiation. For example the optical fiber gratings prepared by UV laser irradiation are one of the key elements for the recent worldwide progress of wavelength division mutiplexing optical fiber network. This paper reviews the representative studies on the photosensitive materials and the origin of photosensitivity in amorphous oxide materials.

Computer is used to analyze nonlinear networks. Integrated circuits and new nonlinear elements have generated much interest in nonlinear circuit theory. A key to the understanding and analysis of nonlinear circuits is the study of characteristics for nonlinear elements and nonlinear resistive networks both in theory and in computation. In this apper, an iteration method using cut set analysis for nonlinear dc analysis based on Branin's method is described. Application of this algorithm to solve two nonlinear problems, is presented and a possible method of improving the basic algorithm by means of a sparse matrix technique is described.
