Developing a network game that is serviced on the internet requires a lot of work, time and manpower. Therefore, it is important to design a game in such a way so that existing design codes could be used. The database for the multi-player network game is accessed from many clients. To manage the resource effectively, it is required to design the APIs to be minimized the database access and to be dealt with the related data efficiently. For this, it is needed to apply the object-oriented design for the related software modules. In the paper, we propose the design patterns of GoF to implement the APIs thatis needed to deal with the database resource. The database design through the analysis of some game's GUI has the advantage to create the optimized schema set more quickly, because it minimize the review step and the modification step of the database design generally. In addition, we apply to the design patterns of GoF for the APIs design of the server-side database. These reduce the times of the program call between the game server and the database server. These also make easily the maintenance for the already developed APIs, and it makes easily the addition of new APIs.

As digital Information equipment is new arrival, new paradigm such as 'function exist but form don't' is needed in the field of design. Therefore, the activity of design is focused on the relationship of human and machine against visual form. For that reason, it is involved emotional factor in the relationship and studied on new field, the emotional interlace. The goal of this paper is to suggest the way of emotional interface on searching multimedia data. The main target of paper is effect sound and human's step and the main way of research is visualization after measuring and analyzing numerically similarity level among emotion-words. This paper suggests the theoretical bad(ground such as personal opinion, the character of auditory information and human's step and case studies on the emotion research. The experimental content about sound is fueled from my previous research and the main experimental content about human's step is made with regression-expression to substitute Quantification method 1 for value about stimulation. The realistic prototype to apply the research result will is suggested on the next research after studying the search environment.

This is a thesis about the whole process of cooperative study for the project, 'Jeju Tamranun idea' which produced by Capstone Design Class in communication design Dept, Hongik University. The purpose of this thesis is to know the primary educational goal and essence of capstone design class and to find the enhancement plan for the local design industry. The exhibitional project, 'Jeju Tamranun idea' was operated three times by hongik university with the company based on Jeju from 2017 to 2019. After the research, There are three positive effects of this project which are the new social function of the discarded assignments, the improvement of educational standard through the autonomous competition, and the growth of students' social consciousness in the process of considering local industries. And there are several points to be reviewed for a better capstone design class with local design industries. It is necessary to utilize the untact system for solving distance issues. And also, absolute evaluations, giving equal reward, and copyright protection are needed. Lastly, the continuous development of the curriculum to improve local design industries is needed.

This paper will propose the efficient method that should be designed to utilize the design pattern of GoF(Gang of Four) for implementation of LBS(Location Based Service) mobile system. The design method proposed by this paper can design and implement system interface using creational patterns, structural patterns and behavioral patterns of design pattern from the user and mobile system viewpoint. The design method using design pattern can show increasing reusability of module and software, abridging the development time, minimizing the maintenance and decreasing the efficiency of memory of system to software development. Therefore, we used a design pattern in order to change the middleware applying geographic information system from mobile environment. Finally, the mobile system applied to design pattern shall contribute to showing high stability and reliability, improving reusability and scalability of module and software and developing efficient LBS mobile system.

In this paper, we develop energy efficient designs for the Fast Fourier Transform (FFT) on FPGAs. Architectures for FFT on FPGAs are designed by investigating and applying techniques for minimizing the energy dissipation. Architectural parmeters such as degrees of vertical and horizontal parallelism are identified and a design choices. We determine design trade-offs using high-level performance estimation to obtain energy-efficient designs. We implemented a set storage types as parameters, on Xilinx Vertex-II FPGA to verify the estimates. Our designs dissipate 57% to 78% less energy than the optimized designs from the Xilinx library. In terms of a comprehensive metric such as EAT (Energy-Area-Time), out designs offer performance improvements of 3-13x over the Xilinx designs.

This paper describes a Voice User Interface(VUI) method and a design guideline tool which supports the studies for domestic appliance. This issue covers specification of user requirement and selection of appropriate VUI to represent speech generation. The criteria for paper is interaction design to enhance user engagement. The studies were carried out to measure prototype of domestic appliance such as a refrigerator, a washing machine, a Gimchi refrigerator, an oven range, a dishwasher and an air conditioner. This paper is presented a study of user preferences and suitability. The results of these findings to voice interface design are discussed and it is suggested that VUI guideline and optimal prototyping can provide a useful application tools in the design process.

This paper presents a method to generate a model of the code implementation for UML state diagrams. First, it promotes the states of a state machine into objects, and then it structures the behavior model on the mechanism of a state diagram based on State design pattern. Then, it establishes the rules of generating the code implementation, and using the rules, the Java code mode is generated for the implementations of State Diagrams in Java syntax grammar. In addition, Structuring the information of the code model is necessary for generating Java code automatically. The meta information is composed of Meta-Class Model and Meta-Behavior Model, on which we could construct the automatic code generating engine for UML State Diagrams. The implementation model generation method presented in this paper could be used as a stand-alone engine, or included and integrated as a module in the UML tools.

본 논문에서는 레이싱 게임에서 도시 맵을 빠르게 생성 및 합성할 수 있는 알고리즘을 제안한다. 레이싱 분류의 게임은 고정된 영역이 아닌 넓은 영역을 이동하는 특징이 있지만 이를 위한 맵을 디자인하고 개발하는 것은 많은 시간을 요구한다. 이 문제는 큰 지형 맵을 전처리 과정에서 생성함으로써 완화 시킬 수 있지만 고정적인 맵은 게임을 지루하게 만들며 그렇다고 다양한 맵을 모두 전처리 과정에서 처리하는 것은 비효율적이다. 이 같은 문제를 해결하기 위해 우리는 전처리 과정에서 지형 패턴을 만들어 실시간에 맵을 생성하고 다양한 맵을 랜덤하게 합성 할 수 있는 기법을 제안한다. 또한, View-dependent기법을 제안하는 프레임워크를 통합시켜 불필요한 렌더링 계산을 줄임으로써 효율성을 증대시킨다. 본 연구는 Unity 게임 엔진에서 개발했으며 레이싱 게임뿐만 아니라 다양한 콘텐츠에서 활용할 수 있다.

비트루비우스(Vitruvius)에서 벤츄리(Venturi)에 이르기까지 많은 건축사가(建榮史家) 또는 건축가(建築家)들이 건축원리에 대한 각자의 규범적 태도를 글로써 밝혀왔다. 이러한 규범적 내용 중 비례이론은 서양건축에 있어 건축미(建築美) 비밀로 간주되어, 조화로운 건축물이 꼭 갖추어야 할 덕목중의 하나로 인식되었다. 현대건축에서 비교적 근대 비례시스템이라 불릴 수 있는 것으로 르 꼬르뷔지에의 모될로르와 반 데어 란의 플라스틱 넘버를 들 수 있다. 모될로르는 현재까지 아주 제한된 성공밖에 거두지 못했는데, 이는 피보나치 수열에 기초한 수치들이 커졌을 때 단위의 배수관계가 거의 형성되지 않는다는 사실에 기인한다. 반면에 플라스틱 넘버는 모될로르의 결점들을 보완할 수 있는 매력적인 수열을 가지고 있다. 이에 본 연구는 반 데어 란의 비례시스템 분석을 통하여 유도된 수열규칙이 건축디자인과 관련되어 직접적으로 적용되어 질 수 있는 CAAD시스템을 제안한다. 본 시스템의 초점은 반 데어 란의 비례이론이 어떻게 컴퓨터 언어로 변환 및 CAAD시스템에 적용되어, 실질적인 건축 실무행위에 있어 컴퓨터가 디자인 도우미로서 역할을 수행할 수 있겠는가하는 것이다. 연구의 결과, 사용자는 이러한 시스템을 사용함으로써 반 데어 란의 비례시스템을 자신의 디자인에 손쉽게 적용할 수 있으며, 이는 복잡한 치수관계로 구성된 비례시스템의 건축실무 활용으로 발전되어질 수 있을 것으로 사료된다.
