For a long time, a number of alarm processing techniques have been researched to reduce the number of actuated alarms for operators to deal with effectively during the abnormal as well as the normal conditions. However, the strategy that the only systems with a few clear technologies should be used as a part of an alarm annunciation system has been adopted considering the effectiveness and the reliability in actual alarm processing systems. Therefore, alarm processing systems have difficult knowledge-base maintenance problems and limited expansion or enhancement defects. To solve these shortcomings, the integrated knowledge-base which can express the general information related to all the alarm processing techniques is proposed and its management tool, Knowledge Input Tool for Alarm (KIT-A) which can handle the data of the knowledge-base efficiently is developed. Since the integrated knowledge-base with KIT-A can manipulate all the alarm information without the modification of alarm processing system itself, it is expected to considerably advance the overall capability of maintenance and enhancement of the alarm processing systems.

This paper presents a knowledge based system to solve reactive power/voltage control problem in a power system. The methods to reduce inference time are proposed in inferring the solution of problem in the knowledge base which consists of heuristic rules and inowledge of experts. A set of indices drawn from the heuristic knowledge on the power system is utilized to make up for the defect of existing knowledge based systems which determine both the location and the amount of reactive power compensation devices. The concept of set of indices developed in this paper makes it possible to infer the amount of reactive power source only since the bus order list representing priority for the location of reactive power compensator to be switched on can be determined in advance. From the fact that there exists a relationship between the system voltage pattern and the reactive power pattern in operation, the pattern recognition technique is introduced to reduce the inference time in solving the severe voltage problem. To demonstrate the usefulness of the proposed knowledge based system, the IEEE 30 bus system is chosen as a sample system. The results of case study are also presented.

The current approaches in Object-Oriented Analysis have limitations on modeling complex real world systems because they require priori knowledge about objects and their interactions before applying them. This may be practical in small systems and systems with clear domain knowledge, but not in large real world systems with unclear domain knowledge. Our approach uses a stepwise refinement technique in a top-down manner to the Object-Oriented Analysis stage with the application of use cases. This approach is especially good for new areas where we do not know all the information in advance. We present the approach with an example of its application to the B-ISDN service modeling and distributed systems.

In a knowledge economy, accelerating the pace of knowledge building and the rapid acquisition of knowledge are keys to innovative development. However, the development of the commercialization of research results and formation of new start-up companies are often not as active as they should be with a lack of motivation and incentive being one of the contributing factors for the failure to take action. In Taiwan and Japan, the reason that widely advocated idea of industry-academia collaboration is to help advance the technological capabilities of research and development as well as produce economic benefit. The assistance rendered by the government during the transformation and the assessment of outcomes from entrepreneurial pursuits are key issues explored in this study. The results indicate that the network system in the national innovation system is important for entrepreneurship development. The domestic market of Taiwan is not as large as Japan and new entrepreneurs have to face global market challenges.

Potential employers considering locations for production or service facilities typically equire detailed advance knowledge of the wages they will be expected to offer for workers in various occupational categories. The State of Missouri s Department of Labor and Industrial Relations is often contacted by organizations requesting such information. The current wage rate survey approach, initiated in 1988, allows the Department to predict an appropriate wage rate for a given occupation in certain counties, adjusted for changes in the Consumer Price Index (CPI). However, both Department employees and firms have indicated that improved prediction responsiveness and accuracy are desirable. A major deficiency of the current approach is its inability to predict wages for unsurveyed counties. This paper describes a knowledge-based system (KBS), currently in the prototype testing stage, that is expected to supplement the wage rate survey in the near future.

This study was to provide the basis for the development of family life education programs for caregiving families. The data were collected from 374 adult children who were giving care to their older parents in Seoul. Adult children reported experiencing more caregiving problems in the areas of personlities of older parents psychological burden and parents' health than in the areas of caregiver's health and financial burden Women were more likely to experience caregiving problems than men. Adult children indicated higher levels of perceived knowledge on planning for later life psychological characteristics of older parents and keeping good relationships with older parents. They reported more need for knowledge on physical change of older parents and planning for later life while there were less need for knowledge on sharing caregiving roles with others and social service programs. The needs for caregiving education were also identified in the aspects as to participation purposes methods times and agencies. Given these findings this study suggests some practical implications for the development of family life education programs for caregiving families. Further studies should help to advance the development and practice of family life education programs for caregiving families.

Objective: This study was conducted to assess the efficacy of subcutaneous granulocyte colony-stimulating factor (G-CSF) for treating thin endometrium. Methods: Data from 88 infertile women with thin endometrium (<7 mm) aged 23 to 40 years were evaluated retrospectively over a period of 1 year. In group 1, subcutaneous infusion of G-CSF (300 ㎍/mL) was administered to 44 women along with other supplemental treatments. If the lining did not exceed 7 mm within 72 hours, a second infusion was administered. In group 2, which also had 44 women, only estradiol valerate and sildenafil were administered, while subcutaneous G-CSF infusion was not. Embryo transfers were performed once the lining exceeded 7.5 mm. The efficacy of G-CSF was evaluated by assessing the thickness of the endometrium before embryo transfer, pregnancy rates, and clinical pregnancy rates. Results: There were no differences between the groups regarding demographic variables, egg reserves, sperm parameters, the number of embryos transferred, and embryo quality. The pregnancy rate was significantly higher in group 1 (60%, 24 of 40 cases) than in group 2 (31%, 9 of 29 cases) (p<0.001). The clinical pregnancy rate was also significantly higher in group 1 (55%) than in group 2 (24%) (p<0.001). Conclusion: Subcutaneous G-CSF infusion improved the thickness of the endometrium when it was thin. To the best of our knowledge, this is the first documented study to clearly demonstrate the benefits of subcutaneous G-CSF infusion for treating thin endometrium.

그동안 전자정부의 지식관리 연구는 주로 조직 내적인 것에 국한하여 왔다. 그러나 최근 시민중심적이고 시민주도적인 패러다임으로의 변화와 웹 2.0 커뮤니케이션의 발달로 조직내부에서 정부와 시민 간 조직외부로의 지식관리의 문제가 중요한 영역으로 부각되고 있다. 이에 일련의 지식강화포털 연구는 시민을 대상으로 하는 포털 상에서의 지식강화가 필요하다는 인식에서 출발하며, 이를 통해 전자정부포털의 유용성을 향상시킬 것을 가정한다. 지식강화와 전자정부(포털)는 각각의 영역에서는 폭넓게 논의되어 왔으나, 두 영역이 만나는 맥락(Joint Context)에서 이러한 구조에 대해 소개한 연구는 드물다. 이를 위하여 본 연구는 전체론적인 접근방식으로 기존의 관련 논의들의 이론적 구조화를 통해 전자정부포털 상에서의 지식강화를 위한 개념적 프레임워크를 도출하는 것을 목적으로 한다. 본 프레임워크는 3개의 변환 단계로 구성되는 지식강화포털의 진화적 경로를 제안하고 있으며, 이는 향후 지식강화포털 프로젝트를 구현하는데 있어 기본적인 참조모델로서 활용될 수 있을 것이다.
