Agricultural ecosystem biodiversity monitoring and community variation analysis of insects were conducted from 2016 to 2018 in selected conventional and organic farming fields in Goesan district, Chungcheongbuk-do, South Korea. The total number of 1,125 species in 16 orders and 207 families were identified. The numbers of species collected in the locations practicing organic farming were greater than the conventional farming both in the paddy fields (564 vs. 383 species) and the upland fields (471 vs. 365 species). Among them, Hemiptera had the most abundant of species, followed by Diptera, Hymenoptera, Coleoptera and Araneae. We calculated various index values of biodiversity (diversity index H’, richness index R, evenness index J’, dominance index D, and similarity index QS) based on quantitative measurements of species and individuals collected over three years of field monitoring. Variations in biodiversity index values in different agricultural systems show that the positive effect of organic farming is to produce more biodiversity than conventional farming systems. When compared to other index results reported in Korea, Japan and China, the richness index was higher and other index values were at similar levels.

The purpose of this study was to investigate the relationship between ⑴ social status and selection of toys, ⑵ sibling order and selection of toys and ⑶ sex and toy preference. The subjects were 97 mothers of preschool children. A questionnaire was devised and used for the collection of data. The data were analyzed with Chi-square. The results were as follows: ⑴ There was a significant difference in selection of toys according to the socio-economic status of children. ⑵ There was no significant difference in selection of toys according to sibling order of the child. ⑶ There were significant differences between boys and girls in toy preference.

본 연구는 학교에서 일반적으로 쉽게 행할 수 있는 성취도 검사로 학습내용의 논리구조가 학습자의 마음속에 발달되어 가는 과정의 심리적 측면의 이해와 수업설계에 도움이 되는 정보를 얻고자 실시하였다. 물리를 이수하는 고등학교 자연과정 남학생들(388명)을 대상으로 하였다. 축소판 GALT(group assessment of logical thinking)로 논리 사고 수준을 조사하였다. 그리고 “힘과 운동” 단원에서 선정한 6개의 개념(변위, 평균속도, 가속도, 힘, 운동량 및 충격량)에 대해 문제 맥락(직선상에서 방향 일정, 직선상에서 방향 변함, 평면상의 운동)에 따라 문항을 작성하고 논리 사고 수준별(구체적 조작기, 과도기, 형식적 조작기)로 개념의 위계구조가 어떠한 모습으로 나타나는가를 비교하였다. The purpose of this study was to find the aspects of the learner's mind, and to provide meaningful information for planning a lesson. In this study, the logical thinking of high school boys at eleventh grade was measured, and the hierarchical structures of physics concepts(displacement, average velocity, acceleration, force, momentum, and impulse) were investigated by logical thinking levels(concret operational stage, transitional, formal operational stage) in each problem context with the method of achievement test. GALT was administered before instruction, concepts understanding test after instruction. Hierarchies were determined by the level of more than 0.7(Alpha-cut) with the hierarchical coefficient on the basis of the fuzzy theory.
