Remodeling becomes the significant issue in the aspect of the resource recycling, because it does not demolishes the whole buildings, but a part of main structure. However, compared with new construction, remodeling has several problems of adding the repair and rehabilitation works, using the partial demolition method, and having difficulties of making decision due to disagreement between several owner organizations. BIM, which is the total solution for managing and producing information during whole life cycle of the buildings, seems to be the right solution for the way to address these issues. has a possibility for solving the problems. Therefore this paper provided the framework and database for applying the BIM in the remodeling, and proved the applicability of the BIM database in the remodeling project through the case studies.

The game industry has been seeing rapid change brought on by the competitive environment globally. As a result, game design skill is being magnified as a key to success. Because of lack of game design skills, Korean game market is in crisis recently. The game analysis is necessary to enhance game design skills. However, criteria and definition of game analysis is not clear and it is difficult to use for game development. This paper will suggest H-G model which has two factors that are 'human role' and 'the scope of game analysis'. This model segments 9 types of game analysis method. This study finds the limitation of leading researches and tries to improve it mapping the major leading researches to H-G model. This paper would help to make the game analysis be integrated and systemic research as regards 9 types of H-G model.

The purpose of this study is to analyze the 'Framework for Information Literacy for Higher Education' filed by the ACRL (Association of College and Research Libraries) Board on February 2, 2015 and adopted on January 11, 2016. Six concepts central to information literacy in Framework and four main theories or models (i.e., threshold concepts, metaliteracy, Backward Design, and Liminal Space) underpinning the Framework were analyzed. The Framework provides conceptual or descriptive approach. In addition, the Framework is not designed to be implemented in a single information literacy session in a student's academic career. Instead, it is intended to be systematically integrated into the student's academic program at variety of levels. This study recommends curricular development and assessment methods supporting Framework as a further study.

Due to recent various online problems, the necessity of information security education has increased. The information security education was strengthened thanks to the informatics curriculum of middle school in 2007, but the educational fields lacked detailed educational materials that could be utilized. Thus to give appropriate information security education for elementary and middle school students, this research developed an unplugged activity for them. The activity was designed by applying Lickona's integrated ethical model and design patterns of unplugged activities, and developed through expert's review and pilot tests targeted to elementary school students. Developed activity was applied to 21 middle school students and the usability was evaluated. As results, first, the activity showed similar expectations from the previous activities. Second, persistence was also similar or higher compared to the previous activities, so the activity developed from this research secured the minimum usability. The unplugged activity developed from this research would give implications in producing various educational contents for information security education.

Capstone design course in current domestic software education environment has been opened in undergraduate courses in order to improve student's practical skills. However, the capstone design course is hardly applied the software convergence trend. We opened the capstone design course in not only the students in certain department, but also the students in other departments in order to solve this problem, and then we analyzed the operating results of this capstone design course. In the analyzed result, we find that operation of the convergence capstone design course is enough satisfactory, but we find that the operation of the convergence capstone design course has the limit that the certain department operates individually the convergence capstone design project. Hence, we need that the convergence capstone design course is preferably operated as the department-integration.

제품을 설계하는 디자이너나 엔지니어는 많은 시간과 노력을 들이지 않고서 그들이 설계한 3차원 제품 모델에 대한 사실적인 이미지를 원한다. 디자인 프로세스의 초기인 개념 설계에서부터 설계검증, 그리고 가공 과정에서 사실적인 이미지가 매우 유용하므로, 대부분의 주요 CAD 제작사는 그들의 CAD 소프트웨어에 고급 렌더링 기능을 추가하고 있다. 상용의 CAD/CAM 모델러에서는 NURB 곡면을 기초로 모델링을 수행하므로, NURB 곡면을 렌더링할 수 있는 패키지가 필요하다. VIF(Visual InterFace) 렌더링 라이브러리는 A-buffer 방식과 Ray tracing 방식의 두 가지 고급 렌더링 모드를 제공한다. 다각형은 물론 NURB 곡면을 입력으로 받아 사용자가 설정한 표면의 각종 계수, 원하는 view와 설정된 광원에 따라 이미지를 만들고 다양한 형태로 출력시킬 수 있는 다양한 기능을 제공한다. 본 논문에서는 VIF 렌더링 라이브러리에 대한 구조와 기능별로 분류된 함수에 대하여 설명하며, 실제로 CAD/CAM 시스템과 통합되어 구상설계에서부터 3차원 설계 모델링에 이르기까지의 제조공정에서 설계검증 툴로써 어떻게 활용되고 있는가에 대하여 기술한다.Abstract Engineers and industrial designers want to produce a realistic-looking images of a 3D model without spending a lot of time and money. Photo-realistic images are so useful from the conceptual design, through its verification, to the machining, that most major CAD venders offer built-in as well as add-on photo-realistic rendering capability to their core CAD software. Since 3D model is consists of a set of NURB surfaces in commercial CAD packages, we need a renderer which handles NURB surface as well as other primitives.A new rendering library called VIF (Visual InterFace) provides two photo-realistic rendering modes: A-buffer and Ray tracing. As an input data it takes NURB surfaces as well as polygonal data and produces images in accordance with the surface parameters, view and lights set by user and outputs image with different formats. This paper describes the overall architecture of VIF and its library functions classified by their functionalities, and discusses how VIF is used as a graphical verification tool in manufacturing processes from the conceptual design to 3D modeling.

The Unified Modeling Language becomes popular to specify, visualize, construct, and document software-intensive systems, especially in supporting the design phase of software engineering. Most of designs in UML have focused on firm designing of software system structure. Recently, some researches have raised additional demands in many emerging complex software systems, such as aspect-oriented design. In this paper, we work on the dynamic aspect of policy-driven architecture. We present a UML-based high-level modeling of policy-driven management which is applicable in various application domains. In order to manage a number of activities of applications, dynamics and flexibility should be supported with policies consistently on different resources in the same context. Thus, a methodology of meta-modeling to represent dynamic aspects of policy-driven architecture is studied. Based on our methodology, we could achieve meta-modeling to develop a number of policy-driven management applications.
