The composition of convergence cross-section of the material is a technique that provides reasonable design and construction of structures. It is frequently used in medium-sized bridges and architectural structures. However, the structural behavioral spare capacity enhancement of the structure by the application of the convergence cross-section is still limited by the expandability due to the limiting state of each material. In order to overcome these limitations, this study reasonably analyzed the construction stages before and after the convergence cross-section constructed and developed a technique for forming multi-point boundary conditions using struts, which are compression members. Based on the existing cases, a reasonable construction step for forming the material composite section of the entire structural system of the structure was derived, and a numerical analysis model for a specific part was constructed to analyze the behavior of the strut application. As a result of this study, the effect of reducing the sectional force of 7.40% in beam-column joint and 6.31% in the center of girder was derived, and the deflection, which is a measure of the serviceability of the structure, improved by 54.41% from the installation and dismantling of strut members at each construction stage.

ISO/IEC 9000에 의하면 품질이란 사용 시 사용자 요구사항을 만족시키는 제품이나 서비스의 특성을 종합한 개념으로 정의하고 있다. 웹애플리케이션의 시큐어코딩은 안정성과 함께 정보시스템 서비스 품질을 결정짓는 요소 중의 하나이다. 시큐어코딩을 달성하기 위해서는 품질을 기반으로 하는 설계 모델이 필요하다. 그 이유는 보안도 하나의 품질 속성으로서 비 기능적 요구사항의 범위에 속하기 때문이다. 웹애플리케이션 품질평가체계 설계를 위해서는 품질의 정의를 기초로 품질속성, 품질요구사항, 품질측정 시나리오가 정의되고 설정되어야 한다. 이를 위해 IEEE 1061 품질모델을 참조한 웹애플리케이션 품질모델 관리체계를 개발한다. 웹 애플리케이션 아키텍쳐 설계는 시큐어코딩 품질모델 체계, 웹어플리케이션 이해관계자 관심 도출, 아키텍처 동인 결정, 품질속성 도출, 보안품질 요구사항 설정, 웹어플리케이션 아키텍처기술서 작성, 보안 프레임워크 설계 순서로 구성된다.

스마트폰의 대중화로 안드로이드 어플리케이션 시장이 급증하였다. 안드로이드 어플리케이션 시장에서 경쟁력을 갖추기 위해서는 높은 생산성, 비용 절감 및 유지 보수가 잘 이루어져야 한다. 또한 어플리케이션의 수요가 높아지면서 짧은 개발 주기가 요구되며 단기간 내에 개발을 진행해야 하므로 개발자는 요구사항 분석 및 체계적인 설계 과정을 생략하는 경우가 많다. 하지만 어플리케이션의 생산성과 비용 절감을 위해 기존 어플리케이션의 전체 또는 일부분을 재사용 할 경우 설계 및 문서화의 생략으로 인해 많은 어려움을 수반되며, 개발 이후 어플리케이션의 유지 보수가 제대로 이루어지지 않을 수 있다. 따라서 본 연구에서는 설계 및 문서화가 생략된 안드로이드 어플리케이션의 소스코드를 대상으로 하여 해당 어플리케이션의 아키텍처를 추출하는 리버스 엔지니어링 방법과, 재사용 가능한 기능들을 식별하는 방법을 제안한다. 제안하는 방법을 통해 안드로이드 어플리케이션의 생산성 증가 및 비용감소와 원활한 유지보수가 이루어지는 것을 기대할 수 있다.

The use of computers in architectural professions has grown with the power of easy data management, increased sophistication of standalone applications, inexpensive hardware, improved speed of processing, use of standard library and tools for communication and collaboration. Recently, there has been a growing interest in distributed CAAD (Computer-Aided Architectural Design) integration due to the needs of direct collaboration among project participants in different locations, and Internet is becoming the optimal tool for collaboration among participants in architectural design and construction projects. The aim of this research is to provide a new paradigm for a CAAD system by combining research on integrated CAAD applications with recent collaboration technologies. To accomplish this research objective, interactive three-dimensional (3D) design tools and applications running on the Web have been developed for an Internet-based distributed CAAD application system, specifically designed to meet the requirements of the architectural design process. To this end, two different scopes of implementation are evaluated: first, global architecture and the functionality of a distributed CAAD system; and, second, the association of an architectural application to the system.

As artificial intelligence technology advances, it is being applied to various application fields. Artificial intelligence is performing well in the field of image recognition and classification. Chip design specialized in this field is also actively being studied. Artificial intelligence-specific chips are designed to provide optimal performance for the applications. At the design task, memory component optimization is becoming an important issue. In this study, the optimal algorithm for the memory size exploration is presented, and the optimal memory size is becoming as a important factor in providing a proper design that meets the requirements of performance, cost, and power consumption.

This study was carried out to find out the reasonable optimum design method for the design of prestressed concrete structures. The optimum design problems were formulated and computer programs to solve these problems were developed. To test the reliablity, efficiency, possibility of application and reasonablity of optimum design problems and computer programs, both continuous optimization method and mixed-discrete optimization method were applied to the design of prestressed concrete composite girder and application results were discussed. It is proved that mixed-discrete optimization method is more reliable, efficient and reasonable than continuous optimization method for the optimum design of prestressed concrete structures.

Educational games offer an opportunity to engage and inspire students to take an interest in every subject material in school. The "fun" obtain when playing games become a trigger for the use of games in learning. However, there are doubts whether the players actually learn while they are having fun. Vidyanusa is an Online Mathematics Education Game being developed by Crayonpedia Education Ecosystem in Indonesia. The learning goal of Vidyanusa is to engage junior high school students in learning mathematics. In this paper, we design the Vidyanusa game material Functions and Relations by using Balanced Design Approach. This approach has three models in succession; the Content Model outlines the purpose of the game, the Task Model maps out the mission, and the Evidence Model outlines student measurement. This paper will then discusses the quality of games produced in term of Usability factor for effective results and objective. The measurement of the game was carried out based on International Standard ISO/IEC 9126-1 FDIS about Software Quality Product.

Traditional architectural space, which is a historical cultural heritage must be connected mutually as a organic flow of various elements such as the environment of the time, political background and values, rather than approaching with fragmentary point of view. The Silhak Philosophy, the basis of late Chosun society developed equity thoughts on the basis of ideology of humanism, and it asserted the promotion of technology and industry as a measure to realize the pursuit of truth which is practically useful. Thus, we could verify the possibility of convergent interpretation of cultural technology of Hwaseong architectural space through the humanistic viewpoint of pioneer spirit of Silhak Philosophy which regards human as a main agent of desire of life, and the pursuit of truth which is useful for reality, and the realization of ethical value by aesthetic practicalism. Based on this, the ontological meaning and value of Suwon Hwaseong by the viewpoint of convergence of culture and technology have been drawn as the construction of planned new town by the practice of filial duty, the plan of city space based on rational values, the realization of a metropolis where self-sufficient economic activities are possible, the introduction of thorough construction management system, the introduction of advanced culture and its creative application, and the application of scientifical knowledges and cutting-edge technology.

최근 탄소중립을 위한 친환경 자동차 권장 정책으로 인해서 전기차와 수소차 이용자가 증가하고 있다. 그러나 기존 내연기관차, 또는 전기차와 비교했을 때 수소차에 대한 인프라는 매우 부족한 현실이다. 따라서 출장이나 여행 등 기존 주거지를 벗어나는 상황에서는 수소차 충전소를 찾는데 어려움을 겪을 수 있다. 본 논문에서는 수소차 이용자들에게 편의를 제공하기 위해서 전국의 수소차 충전소의 위치를 구글 지도에서 보여주고 충전소의 사진과 전화번호를 쉽게 확인할 수 있는 애플리케이션을 설계 및 구현하였다.

보행보조기를 사용하는 노약자나 환자들의 경우는 대부분이 다리의 힘이 부족하여 장시간 걸을 수 없기 때문에 보행 중간에 잠깐씩 쉬어야 하는 경우가 많다. 따라서 육체적으로 약화된 노인이나 환자들이 안전하게 보행을 실시할 수 있도록 보행 능력을 보조하면서도 생체측정 및 IT응용 제품을 사용할 수 있도록 추가적인 다기능 보행보조기의 개발이 절실히 요구되고 있다. 본 연구는 기존 보행보조기의 한계를 극복하기 위해 노인 중심의 새로운 가치가 부여된 보행보조기의 디자인에 관한 내용으로써, 허리가 굽은 고령의 노인을 위한 보행보조기 중심으로 진행되었다.
