Domestic apartment housing has been designed in accordance with the new housing supply-driven policies for a long time. As a result, its design, material production, construction, maintenance and remodeling process, rather than being systematically performed, were individually approached to cause insufficient linkage between technologies. For these problems and the supply of long life housing, active research on long life housing has been conducted in Korea since 2005. However, the existing research on long life housing has been focused on a single item with no connection made between infill systems, and no overall interface rule, resulting in no activation of the business. In this study, for the supply and activation of long life housing, we aim to analyze the problems of existing long life housing to set up its matching standards for infill systems.

Recently, business application vendors have responded to customer demand with several technological and organizational changes for reflecting network-oriented process flow with electronic communication and expanding their market. In organizational changes. Vendors are adding new functionality to their core offerings through mergers and acquisitions, or by partnering with front-office operation and SCM vendors. And technological changes are embracing the development of component-based application and middleware technology to be possible with integration of their function modules. We will present the design and development process of component-based SCM system to be integrated with heterogeneous ERP under implementation. Especially, we survey and analyze the technology related with CBD(Component-Based Development) to be adapted this research - component's design and methodology, the interface for component integration, middleware's development methodology of Enterprise Middleware vendo to bundle various types of middleware into a single package product with easy-to-use interface.

Knapsack problems represent many business application such as cargo loading, project selection, and capital budgeting. In this research we developed a knapsack problem solver based on Martello-Toth algorithm using a relational database management system on the PC platform. The solver used the menu-driven user interface. The solver can be easily integrated with the database of decision support system because the solver can access the database to retrieve the data for the model and to store the result directly.

현재 위피 응용프로그램을 개발하기 위한 저작도구는 코드 작성의 편의성이 부족하고, 시각화를 배제한 문법 중심의 프로그래밍 도구가 대부분이다. 이로 인해 위피 응용프로그램 개발 시 개발자가 전체 개발과정에 걸쳐서 직접 코딩하여 개발하고 있다. 본 논문에서는 위피 응용프로그램을 신속하고 용이하게 개발 할 수 있는 절차로써 위피API의 상위레벨(High level) 컴포넌트를 그래픽 컨트롤로 시각화하고, 이를 이용하여 시스템에서 제공한 모바일 레이아웃에 개발자가 쉽게 디자인한 후, UI 명세 언어와 소스 코드로 생성 해주는 과정을 거치는 개발 방안을 제시한다. 이를 위하여 위피 Jlet의 UI 명세 언어인 JIML(Jlet Interface Markup Language)을 제안하고, 제안한 JIML로부터 위피 Jlet의 UI와 관련된 위피 코드로의 생성을 위한 변환 규칙을 제시한다. 또한 위의 개발 과정을 자동으로 처리하는 시스템을 구현하였다. 구현한 시스템은 위피 비즈니스 프로그램 개발 시 효율성을 제공하고, 빠른 개발이 가능하도록 도와준다.

The major components of IoT(Internet of Things) environment are IoT devices rather than the conventional desktop computers. One of the intrinsic characteristics of IoT devices is diversity in view of data type and data access method. In addition, IoT devices usually deal with real-time data. In order to use such IoT data for internal business or cloud services, an IoT platform capable of easy domain management and consistent data access interface is required. This paper proposes a Linux FUSE-based virtual file system connecting IoT devices on POSIX file system view. It is possible to manage IoT domain with the native Linux utilities such as mkdir, mknod, ls and find in the file system. Also, the file system makes it possible to access or control IoT devices through POSIX interface such as open(), read(), write() or close() without any separate APIs or utilities. A test result shows that the management performance of the file system is lower than that of linux file system negligibly.

The recent development of IT, consolidation of communication and multimedia technology have brought enormous changes in many organizations. Theses changes are enabling the new educational opportunities such as distance teaming and virtual class room. Recently, e-Learning has grown rapidly in business training field, In the context of companies, e-Learning has merits in terms of access convenience, costs reduction self-directed learning, reciprocity, and flexibility. In this regard, the primary purpose of this study is to investigate which factors of e-Learning influence the effectiveness of education and transfer of loaming in business organizations. Based on the prior studies of the education and business training field, research model and research hypotheses were developed. Factors studied in this paper were as follows: 1) learners' characteristics, 2) organizational support and 3) system environments. The results of our study are as follows. (1) Motivation perceived usefulness in Learner factors had an significant influence on both learning effectiveness and transfer of teaming, whereas Ability, expectation had an influence on transfer of teaming. (2) Support from peer, support from supervisor in Organization factors had an significant influence on both Loaming effectiveness and transfer of teaming, whereas support from organization had influence on learning effectiveness. (3) Appropriate contents in system circumstance had an significant influence on both teaming effectiveness and transfer of teaming, whereas interface design had an influence on learning effectiveness.

Peer-to-peer systems (P2P) are rapidly growing in importance on the Internet environment, quickly extending the range of their usage. However, peer-to-peer systems have not been widely applied in electronic commerce because they have not been established as an appropriate business model. Therefore, we firstly review the previous research relevant to peer-to-peer systems, and then analyze the business models for P2P systems presented by previous researchers. Furthermore, this study categorizes major issues in terms of the technical and business model aspects. On the basis of these reviews, we develop P2P electronic commerce systems based on the file sharing method between users, focusing on user interface friendliness. A developed P2P electronic commerce systems are programmed by using the C# based on the Microsoft.net solution. A database is implemented using the MSSQL2000. A main application technology is designed that P2P electronic commerce systems make it possible. for user to extend into BtoB Solution by using WSDL (Web Services Description Language), UDDI (Universal Description, Discovery, and Integration) and the XML that is a document for users. User interface is made as form of Internet messenger for a user's convenience and is possible to develop into a commodity transaction system based on XML. In this study, it is possible for the P2P electronic commerce system to have extended application to fields such as Internet shopping mall and property transaction in a nonprofit organization, a public institution and a large scale nonprofit institution that have a similar structure as compared with a structure of a nonprofit educational institution.

ERP 시스템은 기업의 기간 시스템으로서 기업이 e-business에 참여하기 위해서는 시스템의 성공적인 운영이 필수적인 요소이다. 그러나 대부분의 ERP 도입 기업들은 ERP 운영에 많은 문제점과 어려움을 가지고 있다. 이는 ERP 시스템에 의해 관리되는 데이터가 부정확하기 때문이다. 본 논문에서는 기업의 핵심 데이터인 물품마스터의 정확성 유지와 물품과 관련된 지식자원을 통합 관리하기 위해 물품 온톨로지의 모델 및 구축 프로세스를 제시하고 이 온톨로지를 효율적으로 관리할 수 있는 온톨로지 관리 시스템을 설계 및 구현하였다. 제안된 모델과 구축 프로세스에 따라 물품 온톨로지를 구축하고 이를 관리하는 온톨로지 관리 시스템을 기업의 기간시스템과 연계함으로써 중소기업의 e-business로의 전이가 용이하리라 본다.
