This study has formed a clear definition of the elements of inquiry skills : inference, determining relationship, causal explanation, prediction, and created the goals of assessment and the items of assessment. They have been checked the validity and the objectivity and the clarity of the items by six professors of science education. At the same time, the two times of the field trial has been executed. and checked the discriminating power and the difficulty index and the effectiveness of distracters, and modified the items. The test developed in this way was administered to 1060 students of the eighth grade, randomly cluster-sampled from the universe, and standardized. The test is the aptitude test as well as the norm-reference test. and has twenty items. The testing-time is thirty minutes. And the cotent validity is 85%, the objectivity of the answer keys 91.7%, the mean of items difficulty 68.8%, the mean of discriminating power 0.39, the standard deviation 3.31, the reliability(K-R 20) 0.69. Because it is the standardized lest, it can diagnose the well-developed skills and the ill-developed skills of the students, and monitor the development of skills.

본 연구는 과학 교과목 학습에 대한 학생들이 가지는 학습적 어려움을 파악하고 기존 연구와 시중에 사용되는 학습 애플리케이션들을 분석하여 U-러닝 시스템을 제안하였다. 사례조사를 통해 기존 대다수 학습 애플리케이션이 가지는 동영상 기반으로 인한 긴 학습시간의 요구와 개방형 학습콘텐츠의 부족으로 인해 학습자들이 자신의 학습 수준을 파악할 수 없다는 점과 양방향 참여가 어렵다는 문제점, 그리고 학습자 수준을 고려하지 않은 교육 콘텐츠 제공과 같은 문제점들을 발견하였다. 이를 보완하기 위해 단기학습 단위의 소규모 학습 콘텐츠, 개방형 학습 시스템, 강화된 계층적인 학습 콘텐츠 등의 설계요소들을 적용하여 새로운 U-러닝 시스템을 설계하였다. 설계된 시스템을 안드로이드 기반으로 구현하여 학습 대상에게 유익한 과학 교육을 제공하였다. 제안한 U-러닝 시스템이 교육 효과가 있음을 보이기 위해 중학생 3학년을 대상으로 설문조사를 실시하였다. 설문조사에서 기존 학습 애플리케이션과 본 논문에서 제안된 U-러닝 시스템을 모두 이용하게 하였다. 분석 결과로서 일방적인 단방향 학습이 아닌 양방향으로 학습에 참여하고, 학습결과를 공유하여 피드백이 가능함으로써 학습효과가 얻어 질 수 있음을 t-검정으로 확인하였다.

감자를 물에 침지시켜 썩히고 전분을 분리 이용하는 것은 우리나라 특유의 식문화이다. 본 실험에서는 감자를 $30^{\circ}C$의 물에 7일간 침지시키면서 전분의 성질 변화를 조사하였다. 침지 중 큰 입자$(61-70\;{\mu}m)$는 침지 1일에 크게 감소하였고 침지 2일 이후에는 거의 존재하지 않았으며, 전분입자는 침지 2일부터 구멍을 보이기 시작하였다. 침지 중 수침액의 pH는 감소하였고, 총 당과 환원당은 증가하였다. 전분입자의 밀도, 아밀로오스 함량, 인 함량 및 지방질 함량은 감소하였다. 전분의 상대결정도는 증가하여 침지 4일에서 가장 높았고 다시 감소하였다. 호화엔탈피의 변화도 비슷한 결과이었다. 침지전분은 산 또는 효소에 의한 가수분해 정도가 낮았고, 팽윤력, 아밀로그라프의 점도 등도 낮았다.

The concept of parish nursing began in the late 1960s in the United States when increasing numbers of churches employed registered nurses (RNs) to provide holistic, preventive health care to the members of their congregations. Parish nursing role was developed in 1983 by Lutheran chaplain Granger Westberg, and provides care to a variety of church congregation of various denominations. The parish nurse functions as health educator, counselor, group facilitator, client advocate, and liaison to community resources. Since these activities are complementary to the population-focused practice of community health' CNSs, parish nurses either have a strong public health background or work directly with both baccalaureate-prepared public health nurses and CNSs. In a Midwest community in U.S.A., the Healthy People 2000(1991) objectives are being addressed in health ministries through a coalition between public health nurses and parish nurses. Parish nursing is in the beginning state in Korea and up untill now, there has been no research was conducted on concrete role of korean parish nurses. The main purpose of this study was to identify, classify and analyze activities of parish nurses. The other important objective of this study was to establish an effective approach and direction for parish nursing and provide a database for korean parish nursing model through analysis and' classification of the content of the nursing record which included nursing activities. This study was a descriptive survey research. The parish nurses were working in churches where the demonstration project developed on parish nursing. The study was done on all nursing records which were working in churches where the demonstration project developed on parish nursing. The study was done on all nursing records which were documented by parish nurses in three churches from March, 1995 to February, 1996. Namsan, Taegu Jeei and Nedang presbyterian churches in Taegu and Keimyung nursing college incooperated together for the parish nursing demonstration project. The data analysis procedure was as follows: First, a record analysis tool was developed and second, the data was collected, coded and analyzed, the classification for nursing activities was developed through a literature review, from which the basic analysis tool was produced and cotent validity review was also done. The classification of the activities of parish nurses showed 7 activitity categories. 7 activity categories consisted of visitation nursing, health check-ups, health education, referring, attending staff meetings, attending inservices and seminar, volunteers coordinating. The percentage of activities were as follows: Visitation nursing(A: 51.6%, B: 55%, C: 42.6%) Health check-ups(A: 13.5%, B: 12.1%, C: 22.3%) Health education(A: 13.5%, B: 13.2%, C: 18.2%) Referring(A: 1.4%, B: 4.2%, C: 2.4%) Attending staff meeting(A: 18.8%, B: 13.0%, C: 12.2%) Attending inservices and seminar(A: 1.5%, B: 2.2%, C: 2.1%) Volunteers coordinating(A: 0.3%, B: 0.4%, C: 0.0%) To establish and develope parish nursing delivery network in Korea, parish nurses role, activities and boundaries of practice should be continuously monitored and refined every 2 years. Also, It is needed to develope effective nursing recording system based on the need assessment research data of various congregation members. role, activities and boundaries of practice and arrangement of the working structure, continuing education, cooperation with community resources and structuring and organizing parish nursing delivery network. Also, It is needed to develope effective nursing recording system based on the need assessment research data of various congregation members.
