Knowledge discovery in databases(KDD) is the process for extracting valid, novel, potentially useful and understandable knowledge form real data. There are many academic and industrial activities with new technologies and application areas. Particularly, data mining is the core step in the KDD process, consisting of many algorithms to perform clustering, pattern recognition and rule induction functions. The main goal of these algorithms is prediction and description. Prediction means the assessment of unknown variables. Description is concerned with providing understandable results in a compatible format to human users. We introduce an efficient data mining algorithm considering predictive and descriptive capability. Reasonable pattern is derived from real world data by a revised neural network model and a proposed fuzzy rule extraction technique is applied to obtain understandable knowledge. The proposed neural network model is a hierarchical self-organizing system. The rule base is compatible to decision makers perception because the generated fuzzy rule set reflects the human information process. Results from real world application are analyzed to evaluate the system\`s performance.

Purpose: This study was done to identify factors (pain stress, perceived stress, pain disability, fatigue, depression) strategies used by elders to cope with pain based on their type of pain belief. Method: Data were collected from 314 elders in community settings in Seoul from September to December of 2007. Cluster analysis, t-test, and ANOVA were used to analyze data. Result: The types of pain belief were classified as the following groups: Self-blame, Enduring & Mysterious, and Short-term & Understandable. Perceived stress (t=2.36, p=.02), social support (t=2.24, p=.03), extent of pain relief (t=2.39, p=.02), and duration of pain relief (t=2.09, p=.04) were important factors for active and passive coping in the Self-blame group. Pain stress (t=2.39, p=.01) and depression (t=-3.99, p=.00) were significantly related to the active coping in the Enduring & Mysterious group. Perceived stress (t=2.55, p=.01) was an important factor in the passive coping in the Short-term & Understandable group. Conclusion: Considering different types of pain belief in elders and factors that are significantly related to different coping strategies, future nursing interventions should be population specific to encourage active coping strategies and to decrease passive coping strategies.

The purpose of this study is to find out some countermeasure to Korean companies entered Chinese market through analyzing an arbitration case resolved by CIETAC applied of Chinese Commission Agency Law and CISG. China create legal relationship between the principal and the third party under Chinese Consignment Contract Law. Korean companies so make sure whether this Contract is included when they conclude international commercial contract. If yes, they have to prove their recognition for the relationship between the principal and the commission agent when needed. If the parties agreed an additional period of time of delivery and the seller do not deliver the goods within this period, this breach might be regarded as fundamental nature and the buyer could declare the contract avoided. In addition, late delivery might also be regarded as fundamental breach when market price is fluctuated. It is understandable that attorney's fees is recoverable one, but it is not understandable that arbitrator's extra expenses such as travel and accommodation expenses is not recoverable with the reason that arbitrator comes outside of the country.

본 연구는 여러 정보환경 또는 정보 디자인 유형 중에서 짧은 정보 노출 시간에 비해 정보 전달력이 강해야 하는 정보유형의 인지력을 높이는 방법을 모색하기 위해 진행되었다. 이와 같은 정보를 본 연구에서는 '고기능성 정보(High-Functional Information)'라고 정의하고, 연구를 위해 7개 항공기에서 사용되고 있는 Safety Information을 중심으로, 고기능성 정보의 주요 속성과 그에 따른 거시적 정보 표현 방법에 대해서 연구하였다. 본 연구는 상황, 순서, 흐름, 구조 표현으로서의 정보디자인인 Safety Information을 기능변수에 대한 활용이 중요한 '고기능성 정보'라고 정의하고, 이에 대한 주요 정보 속성을 Accessibility, Errorless, Understandable, Timeliness로 제시하였다. 고기능성 정보는 맥락에 따라, 시각적 재현 측면에서 Understandable, Accessibility 속성이 충족되어야 하며, 사용자 조작 측면에서는 Errorless, Timeliness 속성이 충족되어야 한다. 각 측면에서의 거시적 표현 방법으로써, 시각적 재현 측면에서 독특 속성을 기반으로 한 속성이론, 도상화를 통한 "현실감지" 최대화, 정보 주도성(Proactivity), 잉여정보와 노이즈 정보의 최소화를 제시하였으며, 사용자 조작측면에서 맥락효과, 일차적 독특성을 중심으로 한 기억부호화, 이중부호화 및 표현 방법 등을 제시하였다. 본 연구에서의 개괄적인 연구 내용을 토대로 앞으로 정보환경 또는 디자인 유형과 속성에 따른 정보 표현방법에 관한 연구가 추진될 예정이다.

This study shows evaluation of how much OASIS meets "the korean web content accessibility guidelines" and analysis of some of the accessibility problems and their solutions in OASIS(Oriental Medicine Advanced Searching Integrated System) which is the only web site that offers papers and project information related to Traditional Medicine in Korea. The evaluation criteria to determine if OASIS is accessible is classified into four sub items; Perceivable - if information and user interface components is presentable to users in ways they can perceive, Operable - if user interface components and navigation are operable, Understandable - if information and the operation of user interface are understandable, Robust - if content is robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies. Based on the measured results, OASIS has just been redesigned and implemented in more accessible and effective way. OASIS that improves web accessibility for the disabled is expected to help them study oriental medicine more easily and conveniently by providing equal access and equal opportunity to use the web.

The main aim of this paper is to discuss the difference between the Euler-Maruyama's approximate solutions and the accurate solution to stochastic differential delay equation. To make the theory more understandable, we impose the non-uniform Lipschitz condition and weakened linear growth condition. Furthermore, we give the pth moment continuous of the approximate solution for the delay equation.

In this paper, we demonstrate that one can teach conditional probability in a manner consistent with many features of the statistics education reform movement. Presenting a variety of applications of conditional probability to realistic problems, we propose that interactive activities and the use of technology make conditional probability understandable, interactive, and interesting for students at a wide range of levels of mathematical ability. Along with specific examples, we provide guidelines for implementation of the activities in the classroom and instructional cues for promoting curiosity and discussion among students.

Net present value (NPV) and return on investment (ROI) are commonly used to evaluate investment in new technologies. Sometimes, however, measuring the value of investment in new IT becomes very difficult due to its wide scope of application coupled with embedded options in its adoption. Therefore, comprehensive but easily understandable methodologies are needed to solve the complicated problems resulting from the complexity of new technologies. This paper employs a real option analysis to evaluate RFID adoption in the supply chain. Real options analysis should be a better way to evaluate a disruptive technology like RFID.
