It is essential for organizations to employ strategies for improving their information systems security. It is also required to consider features of information systems security strategies which affect their successful and efficient implementation in organizations. This paper identifies those features from various information systems security and strategies literatures.

Scientific collaborations and observational programs have been on-going between astronomers in Korea and the Steward Observatory/University of Arizona. I will present such existing collaboration models/examples between research groups or individuals and astronomers in KASI or in other institutions and universities in Korea. Building on existing collaborations we would like to further develop opportunities for future scientific collaborations and encourage scholarly exchanges between students, researchers, and faculty members in Korea and Steward Observatory/University of Arizona. In this talk I will also discuss current status of observational programs of Korean astronomers using U of A facilities (MMT and Magellan), as well as successful collaboration examples between Steward Observatory and astronomical institutions in other countries.

As long as the prognosis of teeth remains a matter of concern, the endodontic-periodontal relationship will be considered a challenge for the clinician. Many etiologic factors, including bacteria, fungi, and viruses, plus other contributing factors, such as trauma, root resorptions/perforations, and dental malformations, play a role in the co-occurrence of endodontic and periodontal lesions. Whatever the cause, a correct diagnosis on which to base the treatment plan is the key to successful maintenance of the tooth. This article reports the successful endodontic management of a furcation lesion in a mandibular molar that was nonresponsive to a previous periodontal surgical graft. The case had presented a diagnostic challenge for the clinicians, and this article reviews the key points that can lead to a correct diagnosis and treatment planning.

The fundamental principles and the role of surgeons and orthodontists to produce successful results in orthodontic treatment combined with orthognathic surgery is not different from those of conventional procedures and FOS: surgery-first-orthodontic-treatment-later approach. The communication and cooperation between surgeon and orthodontist is of crucial importance. In FOS, the pre-surgical orthodontic preparation is not carried out in the patient's mouth, but in the mounted stone model and in addition to the simulation of tooth movement, to get a precise surgical occlusion, the entire steps of treatment should be simulated on the articulator as well. Right after the surgery, due to the instability of the occlusion, appropriate post operational care should be given according to the surgical technique applied to the mandible by use of final surgical wafer about 8 weeks.

E-business might be characterized by open system through internet, fortification of relationship between the suppliers and customers in chain system of company, the collaboration among partners and the use of IT. For these characteristics, e-business companies are becoming to suffer such burdens as wide spread of global economy, industry deregulation, and the increasing number of new entrants. In this situation, e-business companies should maintain the flexible system to adapt fast changing environment. Information system planning has been the important research area for many years because of its strategic importance. Among various variables, organization and IS context have been researched for making successful ouput of ISP. In this paper, I studied the importance of flexibility in e-business environments. And further I examined the flexibility of IS, organization and ISP methodologies. The forthcoming paper, I expect to investigate the relationship between IS flexibility, organizational flexibility, ISP flexible methodologies and successful ISP.

The purpose of this study is to explore the success factors of successful merchants. To do this, we review the successful story of merchants in Korea and Japan. We found that various success factors such as product differentiation, competitive price, flexible operation, and entrepreneurialism. As a result, it is important to find that large companies can not to do because of managerial systems. Thus, merchants have to analyze and benchmark the management strategies of competitors and development specialized managerial techniques for business operation.

This study proposes strategies for information requirements analysis (IRA) for successful agricultural management information system (MIS) development. The study frist defines IRA based on literature review and emphasizes the importance of IRA by its position in SDLC (System Developments Life Cycle). Then, the study reviews fifteen cases of agricultural MIS development projects appeared in the report of all the MIS related ARPC(Agricultural R&D Promotion Center) projects from 1995 to 1998 and finds that IRA is not properly performed in most of the projects. Finally, this study proposes seven strategies for IRA for successful agricultural MIS development based on the finding of this study and those from the literature related to IRA methods.

The number of business incubator (BI), introduced in Korea in the early 90's, has grown rapidly in the last 10 years, reaching 342 by 2002. Most of the incubator was supported financially by the Small and Medium Business Administration (SMBA), and 83% of them are run by college or university. To develop successful plans for college business incubator, we studied the relationship between a college incubator and its tenants through a systematic questionnaire, and compared royalty systems of four college BI's. It was found out that the tenants wants more flexible advisor system and closer relationship with the professors to solve the technical difficulties. The royalty system is important for BI's to survive without the financial assistance from the government, but the royalty systems of the four college BI's studied in this report have some practical shortcomings and needs amendments.

Boosting, one of the most successful algorithms for supervised learning, searches the most accurate weighted sum of weak classifiers. The search corresponds to a convex programming with non-negativity and affine constraint. In this article, we propose a novel Conjugate Gradient algorithm with the Modified Polak-Ribiera-Polyak conjugate direction. The convergence of the algorithm is proved and we report its successful applications to boosting.
