It is critical to manage risks to complete IS(Information Systems) projects successfully. Identifying risk factors would be the first step for the project risk management. Previous research has discussed the issue with various points of view, such as different risk factors based on project types and roles involved in their projects. This paper empirically explored how people perceive different risk factors by project development methodology, between self-developing IS using programming language like C, Visual Basic and adapting software package already developed by software venders like ERP, CRM packages. There are researches regarding project risk factors for project management in the several point of views. And there are also researches regarding comparison between self-developing and adapting software packages methodology in IS project. However, there are no study on project risk factors comparison between self-developing IS using programming language and adapting software packages already developed by software venders in IS project. This research can be differentiated from previous ones, because it was considered both point of project risk management and development methodology in IS project. This research results implied meaningful messages to enterprise company to be planned IS projects and people who involved in IS projects. They should consider and need to prepare differently according to each development methodology for preventing project risks. It makes them reduce project risks in each case and complete successfully IS projects. Especially, if they have no experiences for implementing software packages, they can forecast the project risks and prepare them in advance.

For lab statistics the statistical package SAS is usually used in PC environment. But most Universities in Korea have bought 'Academic Initiative Package chair licence', which allows to install SAS to student lab PCs only. Most students are hardly able to afford to purchase a licence for use of SAS in their PCs at home or other places than school. It would be very convenient to have a web-based SAS system, physically located inside a campus, which university students can use through internet. In this paper we report the web-based SAS system implemented for the lab purpose of Yeungnam University using SAS/Intrnet module. We overcome some Server-Client environmental difficulties not allowing use of the SAS command 'infile' by implementing modules with PHP language. In the system, users can see and execute some basic SAS sample codes by clicking buttons, which makes students feel comfy in SAS programming.

When a semiconductor package is assembled, various materials such as die attach adhesive, lead frame, EMC (Epoxy Molding Compound), and gold wire are used. For better preconditioning performance, the combination between the packaging materials by studying the compatibility of their properties as well as superior packaging material selection is important. But it is not an easy task to find proper packaging material sets, since a variety of factors like package design, substrate design, substrate size, substrate treatment, die size, die thickness, die passivation, and customer requirements should be considered. This research applies case-based reasoning(CBR) technique to solve this problem, utilizing prior cases that have been experienced. Our particular interests lie in building decision support model to aid the selection of proper die attach adhesive. The preliminary results show that this approach is promising.

Currently, many companies are trying to be more competitive by implementing the most appropriate software package, called ERP (Enterprise Resource Planning). ERP can support the company's business process. A repository, which can story and retrieve enterprise-wide information, is a key component of such software package. This paper implements an enterprise repository for the ERP. A wellknown repository standard, IRDS (Information Resource Dictionary System), is employed for the repository architecture. A meta schema that can help develop database, business applications, models, and workflow is proposed. To illustrate the practical usefulness, a real-life ERP prototype is built within the framework of the proposed repository.

Availability of defect test algorithm that recognizes exact and standardized defect information in order to fundamentally resolve generated defects in industrial sites by giving artificial intelligence to SAT(Scanning Acoustic Tomograph), which previously depended on operator's decision, to find various defect information in a semiconductor package, to decide defect pattern, to reduce personal errors and then to standardize the test process was verified. In order to apply the algorithm to the lately emerging Neural Network theory, various weights were used to derive results for performance advancement plans of the defect test algorithm that promises excellent field applicability.

Like in other trade negotiations covering comprehensive sectors, it is reported that KOREA-US FTA tried so-called 'package deal' at the last minutes, when telecom services sector was positioned at the forefront and expected to partly play a role in buffering US' market-opening pressure on other sectors. Before everything else, Korean negotiators had to enhance the value of foreign ownership deregulation in telecom services sector as a leverage in the course of KOREA-US FTA negotiations. In addition, since foreign ownership change, if any, is highly sensitive issue either politically or policy-wise, it seems very difficult to find a breakthrough. Focusing on foreign ownership regulation in telecom services sector, this paper seeks how Korea has developed its strategic reasoning for negotiations and evaluates the outcomes of KOREA-US FTA negotiations.

인터넷 망에서 멀티미디어 컨퍼런스를 실현하고자 하는 노력은 이 십여년도 넘게 지속되고 있으며, H.323기반의 컨퍼런스 제어에 대한 표준 기술 및 관련된 많은 응용들이 개발되어 왔다. 그러나, 이러한 연구 노력은 표준 기술의 복잡성 등의 문제를 안고 있다. 반면, 인터넷 망에서의 멀티미디어 컨퍼런스에 대한 사용자의 요구는 점점 증가하고 있는 추세이다. 이러한 사용자 요구와 기존의 컨퍼런스 표준 프로토콜의 취약점을 해결하고자 하는 노력이 최근 IETF를 중심으로 이루어지고 있으며, 현재 VoIP 분야에서 H.323을 대체하고 있는 SIP을 사용하여 멀티미디어 컨퍼런스 제어에 적합한 표준 기술을 제정하고 있다. 본 논문에서는 SIP 기반의 컨퍼런스 시스템에서 컨퍼런스 상태정보를 처리하기 위한 컨퍼런스 이벤트 패키지에 대해 살펴본다.

FOTA는 무선기능이 장착된 Mobile Device에 새로운 Software에 대한 알림기능이 도착하면, Software가 탐재된 서버에 접속하여 Software를 Download 받고, 그 Download한 Software를 Upgrade 하는 기능을 말한다. FOTA 기능을 장착하기 위해서 Mobile Device는 Delta Package의 사이즈를 최소화하기 위한 특별한 Binary 구조를 가지는데 두 Binary의 차이를 압축한 것을 Delta Package라고 부르며, Binary 사이에 Upgrade를 위한 여분의 Gap을 두어, 향후 수정된 내용이 있을 때, 수정사항을 공간 내에 포함할 수 있도록 한다. 바이너리를 구성하는 Object들이 Image내에 어떤 위치에 포함될 것인지를 결정하는 Scatter Loader에 따라, Binary의 구조 및 확장성, Delta의 크기를 결정하게 되는데, 이것은 Object의 Type이나 Scatter Loading File내에서 명시한 순서와는 관계가 없고, Execution Region의 분할 개수를 늘릴수록, 각 Object의 Dependency 별로 묶을수록 Delta Size가 작아지는 것을 알게 되었다. 이 논문에서는 위에서 제시한 조건이 Delta Size에 미치는 원인에 대해 분석하고, Scatter Loading File을 최적화시킬 수 있는 방안에 대해서 연구한다.

Recently there are so many media contents created and used by variety routes. Therefore, it is essential to make a new platform which is used for distributing media contents include IPTV. With open IPTV service, developing the new platform became even more important. Because open IPTV makes it possible for consumers to choose contents regardless of contents of the providers. The new platform has to accept current variety service structure. MPEG-21 multimedia framework was developed to satisfy these needs. It presented the distribution framework of the contents but didn't restrict the particular solutions for protecting the rights. In this paper, we present authoring and consuming system for package contents based on MPEG-21 Multimedia Framework for distributing media resources and managing the license of multimedia contents
