This paper provides an outline of mathematics education based on the classroom ecology. Ecology is the subject that concentrates on the relations of human and environment. As mathematics education consists of many factors, it is natural that mathematics education should be interest in the perspective of ecology. This paper examines the meaning of ecology and classroom ecology of mathematics education in the perspective of ecology. And it provides the directions of ecological mathematics education. In special, I set the frame of mathematics classroom in the perspective of ecology. The ecological structure divides microsystem(teacher, student, content), mesosysten(relations of microsystems), exosystem(school), and macrosystem(the objects of mathematics education). Lastly, I suggest the ways of mathematical learning and research of classroom ecology in mathematics education. For we should focus the improvement of students' mathematical ability, we must search for the various teaching and learning methods and the ares of research in the perspective of ecology classroom. Therefore, we should be interested in the classroom environments as well as teaching methods, contents based on the ecology classroom in mathematics education.

The subjects of this study were 258 Korean-Chinese parent-child dyads of an elementary school in Yanbian Province, northeastern China. Research questions covered relationships among children's school adjustment and ecological factors, significance of factors within ecological levels, and direct and indirect effects in causal relationships. Results showed significant effects within each ecological level. Achievement motivation of the individual system, home environment and social support of the microsystem, and mother's job satisfaction in the exosystem had significant relationships with children's school adjustment. Mother's education and job satisfaction influenced school adjustment through home environment; the causal relationship between social support and school adjustment was mediated by achievement motivation. Personal and general factors from each ecological level were more significant than ethnic related factors in explaining children's school adjustment.

공원법이 제정된 이후 40여년 동안 어려운 여건 속에서 공원녹지분야의 양적 발전이 이루어져 왔다면 21세기에는 질적 발전이 이루어져야 되겠다. 도시계획의 틀속에서 최소한의 공원녹지가 지정, 조성되어 관리되고 있으나 지정된 공원녹지가 사유지인 곳이 많기 때문에 공원조성 뿐만 아니라 적절한 녹지관리가 어려워 자연보호식 녹지보호나 식묵행사에 그치고 있는 실정이다. 한편 변화하는 시민 요구와 도시환경에 발 맞추어 도시환경보전과 경관보전을 위한 녹지체계 수립이나 관리목표를 세분화하지 못하고 체계적이고 선진적인 도시녹지관리가 이루어지지 못하고 있는 실정이다. 체계적이고도 질적인 도시농지관리로 전환하기 위해서는 저확한 녹지실태 조사와 수요를 토대로 녹지체계정립, 녹지종류의 조정, 녹지종류별 생태학적 관리목표설정 및 세부지침이 선행되어야 한다.

Purpose: This study was conducted to identify current health care management and barriers in health care management according to ecological systems, and to develop an ecological model for enhancing health care in child care centers. Methods: Focus group interviews were conducted with directors and teachers of child care centers, and with parents of children enrolled in child care. Data were analyzed by the latent content analysis method. Results: Twelve categories of health care management were identified. Barriers to child health care included knowledge deficit and lack of competence in health care by teachers, lack of useful health care manuals, non-existence of professional child health care personnel in child care centers, lack of mutual information sharing and disagreement on child health conditions between child care personnel and parents, lack of specific health related child care inspection criteria and time flexible child care centers with a lack of policy on collaboration with health care facilities. The ecological model developed included specific strategies to improve health care management in child care. Conclusion: The proposed ecological model to improve child health care management should be useful to plan future health care program considering both the immediate and indirect social environment surrounding children in child care.

In the present study, we studied the change patterns of adolescents' overt aggression during the middle school 2nd to the high school 1st grades and the effects of ecological factors on the change. For the research goals, we applied multi-level models to the Korean Youth Panel data. Results showed that adolescents' overt aggression decreased significantly during the period. Gender(males recoded as 1) and self-control had negative effects on the initial status(middle school 2nd grade) while the number of delinquency peers had a positive effect. On the other hand, gender and self-control showed positive effects on the change rate. The major strengths of the research are the study of various ecological factors and the longitudinal design. Few studies of adolescents' aggression have incorporated these methodological and substantive characteristics.

어류는 분류학자 및 수산 관련 전문학자의 뿐 아니라, 어민, 수산 관련 사업자, 낚시 및 수족관 관련업자들도 깊은 관심을 가지며, 일반인들의 식탁이나 주변에서 접하는 어류에 대한 정보를 알고자 한다. 이렇게 어류는 다양한 계층이 관심을 가져, 국내외에 수많은 어류 DB가 service 중이다. 이러한 DB 가운데 본 보고에서는 생물학적.생태학적 정보를 제공하는 DB를 살펴보고 앞으로의 방향을 제시하였다.

세계의 민족에게는 그 나름대로의 식문화가 있다. 무엇을 취하여 어떻게 조리하여 어떻게 먹고 있는가가 세계 각지에 따라 다른 점이 많다. 한국 ${\cdot}$ 중국 ${\cdot}$ 일본의 동아시아 삼국에도 비슷하면서도 서로 다른 식문화가 자리 잡고 있다. 식문화의 본질은 사람들의 정신에 잠재해 있는 음식이나 식사에 대한 태도를 결정하고 있는 즉, 사람들의 음식에 대한 관념이나 가치체계라고 할 수 있을 것이다. 먹는다는 것에 관한 ‘물질’이나 ‘기술’이나 ‘인체의 메커니즘’을 소위 말하는 하드웨어라고 한다면, 그것은 소프트웨어에 해당하는 것이다. 그러나 이러한 관념이나 가치체계는 인간이 처해 있는 환경 즉, 생태학적 환경으로부터 많은 영향을 받을 수밖에 없다. 즉, 전통적인 식문화라는 것은 각 지역의 생태학적 환경에 어떻게 지배되어 왔는가라는 것을 간과해서는 논할 수 없다는 것이다. 여기에서는 수많은 음식 중에 주로 육류에 관한 한 ${\cdot}$ 중 ${\cdot}$ 일 동아시아 삼국의 식문화에 대하여 기술하기로 한다.

This study analyzed the contents of reading textbooks of Chinese-Korean $1^{st}$, $4^{th}$, and $7^{th}$ graders in Yanji, China with reference to ecological systems and values. Results showed that the literature genre of Korean textbooks in China was predominantly novels/stories(38.5%) rather than essays(13.7%), poems/verses/rhymes(16.2%) or others(31.6%). Characters were classified into 9 categories and analyzed by Bronfenbrenner's ecological paradigm. It was found that Chinese-Korean textbooks included more characters belonging to exo- or macro-systems including school, community, and government while Korean textbooks emphasized the self or the family, both belonging to the micro-system. Values in Chinese-Korean textbooks emphasized community and government. Korean textbooks emphasized individual life. Differences were more pronounced in textbooks of the upper grades.

The weapon system has developed by adding various functions because of the warfare change. And, an weapon system test set (WSTS) that is used to test and judge the condition of weapon system also deal with a lot of complex information. However, almost WSTS is developed on the basis of developer-centric. Because of it, it is hard to make a result by apprehending information on WSTS's display. Thus, I proposed a new display of WSTS by adapting the Ecological Interface Design(EID) Methodology to reduce operator's cognitive workload and assure safe testing. WSTS's Display is developed through Information Requirement and Work Domain Model as a result of Work Domain Analysis. The most powerful thing in the new display is that operator can identify his testing and status of WSTS directly. I expect that it reduces operator's cognitive workload and helps safe testing.

퇴적물 오염 평가는 크게 화학적 평가, 독성학적 평가 그리고 생태학적인 평가로 나눌 수 있다 (Long et al. 1995) 최근 국내에서도 오염된 연안의 저서환경에 대한 과학적이고 체계적인 평가 방법에 대한 관심이 크게 증대하고 있다. 그러나 아직까지 퇴적물을 비롯한 환경시료에 대한 독성학적인 오염 평가에 대해서는 많은 연구가 이루어지지 못한 실정이다. (중략)
