With a sample of 147 Korean small and medium size companies, this study examined the relationships among degree of information orientation, corporate culture, degree of information management implementation and selected business performances in the process of implementing IMS improvement programs, such as IMS(Information Management System). Information orientation is defined as company-wide understanding and implementation of the underlying philosophy, principles, approached, and tools of information improvement programs. It is assumed that successful implementation of information improvement programs requires a information-oriented mind-set of the employees. The key elements of information orientation include continious improvement structured processes, organixation-wide participation and customer-focused spirit. Culture id defined as the value and beliefs of em organization that shape its behavior. It is also assumed that successful implementation of information improvement programs require strong support from s corporate culture that emphasizes cintinious improvement. Adopting the competing values model of Quinn and McGrath(1985), corporate culture is classified into 'flexible' versus 'controlled culture' and 'outer-directed' versus 'inner-directed culture'. Fitness was defined through the relationship between levels of information oriented and types of corporate culture. The results were as follows. First, it was found that when a company with high information orientation promoted information innovation programs, such as IMS, it reported higher degree of information management implementation and improvement in business performances. Second, the results showed the importance of 'flexible culture' and 'outer-directed culture' in performing information, innovation. Regarding the types of corporate culture, the analysis found that developmental culture, rational culture and group culture were effective. Third, companies with high information oriented and flexible culture or companies with high information orientation and outer-directed culture reported the highest implementation in Information management activities. Fourth, the results showed that the level of information management implementation had a mediating effect on the relationship between information orientation and business performance. It was also found that enhanced non-financial performance led to the improvement of financial performance. This study attempted to exaime the factor that lead information management program to success. In order to reach success, first, it is suggested that companies have positive mind set toward continious information improvement. Secondly, it is recommended that a flexible and outer-directed culture appropriate for continious information improvement is cultivated.

Face recognition technology has lately attracted considerable attention because of its non-intrusiveness, usability and applicability. Related companies insist that their commercial products show the recognition rates more than 95% according to their self-testing. But, the rates cannot be admitted as official recognition rates. So, performance evaluation methods and tools are necessary to objectively measure the accuracy and performance of face recognition systems. In this paper, I propose a reference model for biometrics recognition evaluation tools, and implement an evaluation tool for the face recognition system based on the proposed reference model.

Partnering concept has been mentioned as an innovative arrangement that helps to reduce many of the disadvantages of the traditional arrangement. Partnering in construction has been widely applied in Vietnam from late 1990s. The application of the new has arrangement spread thanks to anecdotal proofs. This concept is quite new to Vietnamese practitioners. It is necessary to conduct study as a lesson-learn of the industry to encourage the partnering implementation. This paper attempts to develop a model, using discriminant analysis, which classifies the partnering in construction projects into success levels. Dedication, teamwork, sufficiency, and balance are the four significant components in discriminant model. The proposed model is helpful to practitioners in developing, adjusting and improving their strategy for partnering implementation.

The dental hygiene process of care is a model for providing integrated dental hygiene care. It was developed by Mueller-Joseph and Petersen in 1995. The purpose of the dental hygiene process is to provide a framework within which the individualized needs of the client can be met. This model enables the dental hygienist to focus on patient need. The process is composed of five components: assessment, diagnosis, planning, implementation and evaluation. The process of dental hygiene has to move from simple clinical procedure to comprehensive and systemic dental hygiene care. The dental hygiene diagnostic model broadens the biomedical dental model to the behavioral model to include health behavior and health function of individuals. The dental hygiene process will provide a mechanism to develop dental hygienist's role and scope of practice in Korea.

An outline of an Artificial Neural Network (ANN) model for bridge condition rating and the results of a pilot study are presented in this paper. Most BMS implementation systems involve an extensive range of data collection to operate accurately. It takes many years to effectively implement a BMS using existing methodologies. This is due to unmatched data requirements. Such problems can be overcome by adopting the ANN model presented in this paper. The objective of the proposed model is to predict bridge condition ratings using historical bridge inspection data for effective BMS operation.

이 연구는 도시 도메인 정보 모델 간의 상호운용성을 확보하기 위해 모델 레지스트리 활용을 제안하였다. 또한, 도시 정보와 데이터 공유, 관련된 표준 및 표준화 활동을 검토하고, 공간 데이터 인프라(SDI)에서의 레지스트리 사례를 분석하여 도시 도메인 정보 모델 간의 정보 공유와 교환을 위한 모델 레지스트리 개념을 제안하였다. 제안된 개념을 구체화하기 위해 끊김 없는 스마트시티 서비스 구현을 전제로 모델 레지스트리를 활용하여 도시 도메인 정보 모델을 연계하는 유스케이스를 개발하였다. 이를 기반으로 기술적 요구사항을 논의하고 프로토타입 개발을 통한 기술 구현과 실증을 향후 연구과제로 제시하였다.

Role-Based Access Control(RBAC) is a flexible and policy-neutral access control technology. But, for large systems, managing roles, users, permissions and their interrelationships is a formidable task that cannot be centralized in a small team of security administrators. Using RBAC to manage RBAC provides addition히 administrative convenience. In this paper we demonstrate the implementation of one of the components of ARBAC99 which deals with permission-role assignment and is called PRA99. We implement it by using EJB component and use Oracle stored procedures to implement it.

In this paper, we will present an array processor for implementation of digital neural networks. Back-propagation model can be formulated as a consecutive matrix-vector multiplication problem with some prespecified thresholding operation. This operation procedure is suited for the design of an array processor, because it can be recursively and repeatedly executed. Systolic array circuit architecture with Residue Number System is suggested to realize the efficient arithmetic circuit for matrix-vector multiplication and compute sigmoid function. The proposed design method would expect to adopt for the application field of neural networks, because it can be realized to currently developed VLSI technology.

Based on investigating and analyzing the cases of advanced foreign universities that have already included ERP courses in their education systems, this study proposed the ways of incorporating ERP courses into Korean universities' curriculums in terms of the following three areas: 1) development of ERP courses, 2) establishment and maintenance of ERP education environment, 3) continuous evaluation and improvement of ERP education implementation. As reasonable ERP courses, "Introduction to ERP" targeted to educating overall basic concepts in ERP system and business administration, "ERP System Implementation" for fostering business process design and system implementation skills, "ERP Programming" such as ABAP for the purpose of customizing ERP system, and "Strategic Use of ERP" dealing with ERP package selection and implementation methodologies of effective utilization of ERP systems were suggested. Regarding the establishment and maintenance of ERP education environment, single server architecture model that contained both database and application was proposed with the intention of set-up cost saving and maintenance efficiency. As for the evaluation and improvement on ERP education implementation, its methodologies were introduced through analyzing the advanced cases. Finally in addition to the above three areas, critical success factors for effectively launching ERP education in the universities were suggested through reviewing the previous case studies.
