생산성 있는 소프트웨어 개발 및 관리를 위한 기술적, 산업적 전략은 웹 환경 하에서 컴포넌트 기반의 소프트웨어 개발(CBD : Component Based Development)로 점차 귀결되고 있다. 나아가 정보 공유의 투명성이나 비즈니스 로직의 독립적 패키징과 같은, 이 두 개의 기술들이 개별적으로 가지는 특성과 장점들을 결합한 웹 서비스로 전환되고 있다. 따라서 컴포넌트 중심의 웹 서비스를 위한 인프라 환경의 지원이 무엇보다 중요하게 되었다. J2EE는 이러한 요구를 수용하기 위한 가장 표준화된 플렛폼 중의 하나로, 다중 계층의 엔터프라이즈 솔루션을 위한 간단한 개발과 전개, 관리 방식을 보장한다. 본 논문에서는 CBD의 완성을 위한 실제적인 접근으로서 J2EE 환경의 EJB 컴포넌트를 위한 코드 자동 생성 도구를 개발한다. 이를 위해 EJB 컴포넌트를 구성하는 코드의 속성들을 분석하여 보편적인 EJB 컴포넌트의 템플리트를 설계하였다. 또한 도구 구축의 과정에서 세부적인 EJB 생성기의 구조와 기능적 특성을 명시화하고 개발에 필요한 EJB 컴포넌트 정보를 정의, 분류하였다.

Recently in order to process forest official task more effectively and scientifically the previous of that which is focused on document and inventory, should be applied with the spatial information technology. Especially, the forest information remote sensing system has to be developed using digital photogrammetry and GIS. In this study the forest information remote sensing system is implemented to manage forest resource and forest official effectively especially by constructing database of forest environment information and cadastral information, overlaying various thematic maps, and performing spatial analysis using GIS and aerial photograph. For this, the attribute data and spatial data of aerial photograph, digital topography map, forest cadastral map, forest type map, forest use map should be reprocessed and stored in Oracle. Also, the user interface is developed by using Visual Basic 6.0 and MapObjects 2.1 of ESRI based on CBD(Component Based Development).

Since their first inception a few decades ago, software components have received much attention mainly due to their alleged benefits of quality and productivity improvement. Despite this, it is yet to be agreed upon what and how components should be designed. This paper aims to bridge the gap by proposing a collaborative process where the voice of the customer is captured and documented by employing the event and entity models. These requirement elements (WHAT) are cross-tabulated in three relation matrices in accordance with the weights provided by the business users. The requirements are fed into the algorithm invented by the authors to optimize the component grouping (HOW). This collaborative process has been successfully validated at an enterprise wide software development project. The process was effective to help the users more actively involved in the design of the system and made the whole process faster and more adaptive to the changes.

In this study, an electronic parts assembly training system using Leap Motion was developed in consideration of the processes actually operated in the assembly process of electronic products. Based on Leap Motion and Oculus VR equipment, the system was developed to transfer user's hand movement data in real time and convert it into hand movement in virtual space so that electronic parts assembly simulation can be performed step by step. Through this, it was confirmed that the user can obtain an experience similar to the actual electronic parts assembly work, prevent errors that may occur during the assembly process, and improve proficiency. It is expected that this thesis will provide directions for the quality improvement and development of various education and training programs for virtual reality-based manufacturing processes.

The development of Korean glaze originated from the development of ash glazes. Ash not only has strong solubility but also can shows the glaze a variety of different colors according to what the glaze has in it as the main component. In addition, it gives a feeling of lucidness and softness. For these reasons, there are a lot of needs for ash and many potters want to take advantage of ashes as glaze. But natural ashes have not been widely used as glaze primarily because it is relatively hard to find or manufacture. Considering the difficulty of finding or manufacturing natural ashes, this study aims to formulate synthetic ash which not only is available to the potters in general but also has the sam ε characteristics as the natural ashes. To achieve this aim, this study examines the characteristics of the pine tree ash, the main component of the glaze of celadon porcelains, and the red pepper stem ash, the main component of the brown glaze, both of which have been used by the Korean traditional potters. In this study, the alkaline component of the glaze. A important ingredient when the ashes are synthesized, was supplied by mixing of $Na_2CO_3$, Chungju limestone and rice straw ash. Furthermore, the synthetic ash, when it shows no change of pH in its composition rate of 6:2:2, was found to be usable as the most stable material. In conclusion, the formula which frits some raw $materials-Na_2CO_3$, Chungju limestone and rice straw ash-can duplicate the synthetic ash which is simila to the natural ash.

It is reported that the success ratio of software development projects has been only 30%. Many causes lower project's chance of success, particularly lack of systematic project management. Especially, moving on the next phase of project with unsatisfactory outputs can be very problematic because it can cause much waste of resource, time and even lead to the failure of the whole project. Peer review and inspection are some of the practices designed to prevent such waste and possible failure. When defects are identified through such progress, each developer has to work on the product component again and fix the problem. This process is called rework. In this paper, we propose a method for improving quality of reworked product component to prevent excessive cost and time consumed caused by moving on the next phase of a project with a problematic product component. More specifically, this paper suggests a rework indicator that measures the level of rework based on its complexity and severity and is used to choose appropriate checking method on reworked product component. The research also confirmed the method's usefulness and effectiveness by applying the suggested method on four projects.

According to the development of information system, many information system and application soft-ware are develop. However, cyber attack and incident have more increased to the development of them. To defend from cyber attack and incident, many organizations has run information security systems, such as Intrusion Detection System, Firewall, VPN etc, and employed information Security person till now But they have many difficulty in operating these information security component because of the lack of organizational management and analysis of each role. In this paper, We propose the formal Cause-Effect Model related with the information security system and administrative mission per each security. In this model, we regard information system and information system operator as one information component. It is possible to compose the most suitable information component, such as information system, human resource etc., according to the analysis of Cause-Effect Model in this paper. These analysis and approaching methodology can make effective operation of each limited resource in organization and effective defense mechanism against many malicious cyber attack and incident.

With the rapid development of computer technology and ongoing destruction of traditional buildings, more and more attention is paid to digital methods for the design and preservation of traditional buildings. Unlike 2D methods, Building Information Modeling (BIM) provides an object-oriented and parametric digital representation way for traditional building components. However, one of the main limitations currently is that parametric information cannot be exchanged between BIM software packages. Therefore each kind of software must have their own parametric library which causes extensive works. In this research, the authors developed an open BIM-based library using an XML parametric approach to solve the above problems, represented traditional components according to an XML schema, and parametrically implemented these XML files in a browser which can be accessed by users for their easy component edit and selection. And then based on the XML file of one component, implemented an Add-on in ArchiCAD for users to parametrically edit and directly utilize. Thus based on these XML files, a browser for users' view and selection purpose and an add-on for users' application purpose were developed. Future research will focus on implementing these XML files in other BIM tools like Revit and Digital Project. If the whole library was to be completed based on this XML approach, an open BIM-based library would be established that all kinds of BIM software users could apply this parametric library for easy modeling of traditional houses.

Component technologies which enable quickly and effectively to develop software have begun to come into the spotlight since early 1990s. Currently, a number of software development works are performed on the J2EE/EJB environment. However component testing is a very complicated task, in addition it requires more efforts than the previous Java class testing. Thus many developers do not perform sufficiently testing works. In this paper we propose an automatic testing method for EJB components based on the in-container testing strategy and implement a testing tool. Since our method builds automatically the test environment for EJB components, it is possible for developers or testers to save their time and efforts at the test preparation phase. Therefore we are convinced that the reliability of EJB components can be increased through sufficient testings with our method.
