As a micro computer or micro processor technology has been advanced, the essential part which consists of electric power system has been changed into intelligent electronic device(IED), that is one kind of embedded system. There are already many parts changed into digital from analog in control and maintenance devices of electric system. These trends make advanced and novel concepts of devices and systems, that we couldn't even imagine in the analog circumstances. Now, the rate's of change is comparatively slower than IT field that is mainly represented by mobile communication, but that is a big change in the history of electric industries. Some people in those field called it Power-IT, and there have been many kinds of researches. Accelerated systems to go digital, users always and continuously demand more convenient, practical, and new functions. So, a lot of electric system manufactures have had tasks realizing many kinds of functions in an electronic device. According to the high-end technologies in semi-conductor and micro-computer field, manufactures can fully satisfy almost all of customer's needs, but there are other kinds of problems, such as large amount of program code, increasing complexity in proportion with program amount, and the hardness of maintenance and revision of the program. So nowadays, the necessity of embedded OS was emerged as a solution, and many researchers and manufactures have concentrated on studies related to embedded OS and its application.

The Ministry of Education established the plan to adopt a new college enterance examination system, so called Scholastic Ability Test for college, from 1994. The National Board of Educational Evaluation had carried out 7 experimental trials for the new examination system. Eventhough, the governmental officials advertised the purpose and characteristics of the new examination system, many students and parents did not understand the essential point very well. In this study the researcher tried to analyze the 7 trial examination items and the first Scholastic Ability Test for college carried out 1993. In this study, the researcher tried to find out all the items appeared in the 7 trials. In the analysis, all the individual items from the 1st trial to the 7th trial were used. The research results showed that the items were evenly distributed in all the four areas(Physics, Chemistry, Biology and Earth Science) of science content; however, they were heavily concentrated on data or information analysis categoris in the inquiry domain. In the domain of context, laboratory context was the major item context. The scores were also analyzed. The results showed that no significant difference between male and female students. However, science track students showed higher achievement scores than the non-science track student. The examination result showed high correlation with the tests routinely have carried out in schools. The over all analysis showed the new examination system showed very different characteristics to the conventional tests. Therefore, for the student to get successful result in the Scholastic Ability Test, they should change the way of study. They should try to understand scientific concepts rather than to memorize them. They should invest their time to carry out real experiments rather than to focus on the princples and laws of science. One of the most important thing would be for the student to apply what they learned to real life situations.

This study examined burdens of primary family caregivers, and family functioning of patients with cancer. In addition, the relationship between two concepts was assessed to develop nursing intervention to reduce the burdens of caregiving, and to improve family functioning. Ninety-two primary family caregivers of patients with cancer at a general hospital in Seoul participated in this study. The patients with cancer aged from 19 to 84 years with a mean age of 51 years, and sixty-one percent were male. About 30 percent of the patients suffered liver and billiary tract cancer. Fifty-six percent of the primary family caregivers were spouses of the patients and 70.7 percent were women. Primary family caregivers' burdens were assessed by the Burden Scale originally developed by Zarit (1980) and Novak & Guest(1989) and modified by Jang (1995) for use in Korea. The instrument consists of six subscales: time-dependent burden, developmental burden, physical burden, emotional burden, social burden, and financial burden. Family functioning was assessed by the Family APGAR developed by Smilkstein(1978). The results were as follows: 1. The average burden score was 86.1, indicating a moderate level of burden. The time-dependent burden scored highest followed by developmental, physical, social, financial, and emotional burdens. The mean score of family APGAR was 9.71; among subjects 82.6% were included in dysfunctional families. 2. Of the characteristics of patients, age, gender, number of admissions, and job were found to be associated with the level of burden. There was no significant difference between patient characteristics and family functioning. Of the characteristics of primary family caregivers, caregiver's perception of patient prognosis was significantly related to the level of burden, and family functioning. Caregiver's sex and age were also related to family functioning. The quality of relationship between a patient and a caregiver was significant situational factors affecting the level of burden, and family functioning. In addition, the income of family, and help from other family members were related to the level of burden. Given the results, it is essential to develop nursing intervention to reduce burden and to improve family functioning, such as support groups.

인간의 정신 작용을 신경 생리학적으로 연구할 때에, 심리적 현상에 수반되는 뇌파 신호에 종종 관심을 갖게 된다. 예를 들어, EEG 신호가 어떤 심리적 사건과 관련하여 시간에 따라 어떻게 변화하는 지에 관심이 있다면, 두피에 부착된 각각의 전극에서 모아지는 뇌파 신호의 파형이 실험 조건에 따라서 시간적으로 어떻게 변화하는 지를 살펴보면 된다. 이처럼 제시된 사건에 수반되어 반복된 실험적 시행의 평균을 통해 얻어진 뇌파 전위를 '사건 관련전위(ERP)'라고 한다. 뇌파는 이와 같이 전통적으로 시간 영역에서 분석할 수 있는데, 여기에 덧붙여 주파수 영역에서도 분석할 수 있다. 신호 분석법의 발달로 주파수축 분석 방법이 뇌파 분석에도 응용되고, 그 결과 뇌파 신호의 주파수 성분과 인지적 해석이 종종 의미 있는 상관성을 보인다. 이런 상황에서, 뇌파의 시간축 분석에 비하여, 주파수축 분석이 아직까지는 충분히 일반화되지 않았고, 관련 인지 과학 분야 연구자들에게 기본적인 개념을 소개하고 이해를 도울 필요가 있다고 생각되어 본 해설 논문을 준비했다. 이에, 본 해설 논문을 통해, 뇌파 신호의 주파수축 분석에 대한 기본적인 개념(예, 위상-고정)과 그 대표적인 분석방법(예, 웨이블릿 변환)을 이해하고, 뇌파의 주파수 대역별 인지적 속성에 대해서도 전반적으로 살펴보고자 한다. 나아가, 뇌에서 서로 다른 위치에 있는 전극들 간의 뇌파 신호들의 위상의 상호 관계 연구를 통해, 뇌의 기능적 연결성 연구를 이해하고자 한다.

There has been a significant decline in the number of rail accidents in Korea since system safety management activities were introduced. Nonetheless, analyzing and preventing human error-related accidents is still an important issue in railway industry. As a railway system is increasingly automated and intelligent, the mechanism and process of an accident occurrence are more and more complicated. It is now essential to consider a variety of factors and their intricate interactions in the analysis of rail accidents. However, it has proved that traditional accident models and methods based on a linear cause-effect relationship are inadequate to analyze and to assess accidents in complex systems such as railway systems. In order to supplement the limitations of traditional safety methods, recently some systemic safety models and methods have been developed. Of those, FRAM(Functional Resonance Analysis Method) has been recognized as one of the most useful methods for analyzing accidents in complex systems. It reflects the concepts of performance adjustment and performance variability in a system, which are fundamental to understanding the processes of an accident in complex systems. This study aims to apply FRAM to the analysis of a rail accident involving human errors, which occurred recently in South Korea. Through the application of FRAM, we found that it can be a useful alternative to traditional methods in the analysis and assessment of accidents in complex systems. In addition, it was also found that FRAM can help analysts understand the interactions between functional elements of a system in a systematic manner.
