Objective: This study attempted to find out if it changes the child's ability to perform daily life activities when visiting the familiar environment and daily living space of children with cerebral palsy and conducting a home activity support program for children and parents. Design: Randomized Controlled Trial Methods: Among 22 children aged 3 to 12 years old, they were assigned to the intervention group and control group. Of these, 12 boys and 10 girls participated in the study. Gross motor function measure and upper extremity function evaluation were used to measure the physical function of children with cerebral palsy, and self-care skills, mobility and social functions were evaluated in the pediatric evaluation of disability inventory. In addition, a parenting sense of competence was used to find out the efficacy of parents in raising children. After the pre-evaluation, basic rehabilitation treatment and intervention programs were applied to the intervention group, and only basic rehabilitation treatment was performed to the control group, and post-evaluation was performed 8 weeks later. Results: As a result of the study, among the items that measured the gross motor function, upper limb function, and daily life performance ability of the intervention group in the difference between the intervention group and the control group, statistically improved in personal processing and movement (p<0.05). In addition, the parenting sense of competence children in the intervention group was statistically significant (p<0.05). Conclusions: The home activity support program will help strengthen the ability of cerebral palsy children to perform daily life as a way to set mutually agreed goals with their families or children and achieve them in a familiar environment.

T-50 인도네시아 수출은 정부의 정책목표를 구현하고 국내 방산업체들의 해외수출활동을 촉진시키는 촉매제가 되었다. 방산수출은 국가의 위상을 높이고 경제적 이익을 창출하는 신성장 동력으로서 인정받게 되었으며 정부의 주요 정책 중 하나로 자리매김하였다. 본고는 T-50 인도네시아 수출 성공의 동인(動因)을 정책 네트워크의 관점에서 분석하여 효과적인 방산수출 정책방향을 제시하고자 한다. 정책네트워크 이론(Policy Network Theory)은 방산수출 지원정책을 수립하고 집행하는 과정에서 각 정책행위자들의 속성과 그들 사이에서 이루어지는 상호작용이 어떤 산출물을 가져왔는지를 분석하는 데에 유용성과 적실성을 갖았다. T-50 인도네시아 수출에 관한 정책네트워크는 정책공동체(policy community) 유형으로서 다수의 정부부처와 이익집단인 방산업체, 그리고 연구기관의 전문가들이 공동의 정책목표 달성을 위해 상호 공감대를 형성하여 범정부조직인 방산물자교역지원센터(KODITS)를 창설하고 이를 중심으로 행위자들이 공식 비공식 접촉을 지속하면서 수출 성공을 위한 전략을 모색하였다. 일부 주요 정책행위자 사이에 대립과 갈등이 존재했으나, 다수의 행위자가 강한 협력의 관계를 형성함으로써 T-50 인도네시아 수출을 위한 정책결정이 효과적으로 이루어질 수 있었고, 그것은 T-50 수출 성공의 중요한 동인이 되었다. 시사점으로 협력적 상호작용에 의한 정책공동체 유형이 방산수출 지원정책의 목표 달성에 유용함을 고려, 미국에 대한 훈련기(T-X) 수출 등 대형 방산수출프로젝트 추진시 범정부차원의 한시적 테스크포스(TF)를 운영할 필요가 있으며 TF에 참여한 기관들이 상호 협력의 관계를 강화할 수 있도록 기관장들간 정기적인 논의의 장 마련 등 제도 절차적 보완이 필요함을 제시하였다.

The objective of this paper is to apply Extended AND-OR Graph (EAOG)-related techniques to extract knowledge from a specific problem-domain and perform analysis in complicated decision making area. Expert systems use expertise about a specific domain as their primary source of solving problems belonging to that domain. However, such expertise is complicated as well as uncertain, because most knowledge is expressed in causal relationships between concepts or variables. Therefore, if expert systems can be used effectively to provide more intelligent support for decision making in complicated specific problems, it should be equipped with real-time inference mechanism. We develop two kinds of EAOG-driven inference mechanisms(1) EAOG-based forward chaining and (2) EAOG-based backward chaining. and The EAOG method processes the following three characteristics. 1. Real-time inference : The EAOG inference mechanism is suitable for the real-time inference because its computational mechanism is based on matrix computation. 2. Matrix operation : All the subjective knowledge is delineated in a matrix form, so that inference process can proceed based on the matrix operation which is computationally efficient. 3. Bi-directional inference : Traditional inference method of expert systems is based on either forward chaining or backward chaining which is mutually exclusive in terms of logical process and computational efficiency. However, the proposed EAOG inference mechanism is generically bi-directional without loss of both speed and efficiency.

인터넷의 광범위한 응용과 더불어 인터넷 보안은 최근 중요한 관심사가 되고 있다. 악의의 행위를 방지하기 위한 보안 시스템은 구성 요소 및 동작의 완결성이 보장되어야만 시스템의 안전성을 보증할 수 있게 된다. 어느 한 부분의 약점은 전체 시스템의 완결성에 치명적인 결과를 발생하게 된다. 따라서 각각의 보안 요소마다 다양한 기법 및 응용에 대한 연구와 시스템적 응용에 대한 연구가 활발히 이루어지고 있다. 본 논문에서는 지문의 특징을 이용한 OTP의 일회용 암호 키를 생성하는 방법을 제안한다. 본 연구는 잘 알려진 강력한 개인 인증요소인 지문 정보를 이용하여 가변적이고 안전한 일회용 암호 키를 생성하였으며, 또한 제안 기법에 대한 시뮬레이션을 통해 성능을 분석하였다.

This research examined the mediation effects of knowledge absorptive capacity (KAC) and knowledge management capability (KMC), between information communication technology (ICT) implementation and firm performance. In the past, studies investigated KAC and KMC separately. While studies of KAC focus on the flow of information, those of KMC focus on knowledge creation triggered by innovative information. However, KAC and KMC are not mutually exclusive and as such we investigated them together in this research. We surveyed 126 companies and analyzed hypotheses with LISREL analysis. This research provided empirical support for the Nonaka's contention that the information processing has a positive effect on knowledge creation. We also found that there is a mediation effect between ICT implementation and firm performance. Not only is there a direct effect of ICT implementation on firm performance, but there is an indirect effect through KAC and KMC. KAC has a positive effect on both KMC and firm performance. However, it has been discovered that while KMC has mediation effect, it is not significant as an independent factor for firm performance.

The Republic of Korea (South) and the Peaples Republic of Korea (North) had agreed to exploit the North Korean rich natural resources starting from the year of 2006. Through this mutual agreement DPRK shall quarantee ROK's investment in the North Korean Mines and supply mineral products for the compasation of the financial investment supported by ROK. In the area of northern part of Korea, many kind of natural resources such as Magnesite, Iron, Gold & Silver, Copper, Lead & Zinc, and Coal are plentifully deposited. In the area of southern part of Korea, however, most kind of natural resources have been exhausted and so presently major minerals such as Gold & Silver, Copper, Lead & Zinc and Coal are being imported and relying on foreign countries in whole quantity of the requirement. On the other hand Northern Part of Korea is making very slow progress in mining and exploitation owing to the lack of investment even though there are rich deposits of natural resources. And in Southern Part of Korea, they have most advanced production facilities and technologies in the world in the fields of Mineral Floatation, Steel Manufacturing, Nonferrous Metal Smelting & Refining and those plants fabrications. A combination of Southern Technologies together with Financial Support and Northern rich natural resources & Labour Power will be a most hopeful, desirable and mutually required 'South-North economic Cooperation' as the mining industries are labour intensive.

Various methods have been used for safety and reliability as it becomes more difficult to ensure safety owing to the increasing complexity and scale of systems. This study aims at making it easier and more efficient to discuss risks and countermeasures for completeness, review, and knowledge transfer by improving methods to create fault tree analyses which focus on the GSN [1], which are among the methods used to describe assurance cases. More specifically, the purpose of this study is to incorporate strategy and context, GSN concepts, along with reason, which is a new concept, into FTA; the study focuses on three points. One point is support for the safety designer to draw a mutually exclusive and collectively exhaustive (MECE) FTA. The second is to make it easier to understand diagrams and meanings of FTA compared with the usual methods. The third is to make creating an FTA more efficient and to pass on existing know-how. Eventually, FTA can achieve completeness, review, and knowledge transfer. An introduction is provided in the first section. Next, the methodology covered in this paper is explained in the second section. The third section describes the proposed notation method based on two proposals made in this paper. In the fourth and fifth sections, results and discussion are provided, respectively. Finally, in the sixth section, conclusions are described.
