  • The United States (US) National Science Foundation's (NSF's) National Ecological Observatory Network (NEON) is a continental-scale observation facility, constructed and operated by Battelle, that collects long-term ecological data to better understand and forecast how US ecosystems are changing. All data and samples are collected using standardized methods at 81 field sites across the US and are freely and openly available through the NEON data portal, application programming interface (API), and the NEON Biorepository. NSF led a decade-long design process with the research community, including numerous workshops to inform the key features of NEON, culminating in a formal final design review with an expert panel in 2009. The NEON construction phase began in 2012 and was completed in May 2019, when the observatory began the full operations phase. Full operations are defined as all 81 NEON sites completely built and fully operational, with data being collected using instrumented and observational methods. The intent of the NSF is for NEON operations to continue over a 30-year period. Each challenge encountered, problem solved, and risk realized on NEON offers up lessons learned for constructing and operating distributed ecological data collection infrastructure and data networks. NEON's construction phase included offices, labs, towers, aquatic instrumentation, terrestrial sampling plots, permits, development and testing of the instrumentation and associated cyberinfrastructure, and the development of community-supported collection plans. Although colocation of some sites with existing research sites and use of mostly "off the shelf" instrumentation was part of the design, successful completion of the construction phase required the development of new technologies and software for collecting and processing the hundreds of samples and 5.6 billion data records a day produced across NEON. Continued operation of NEON involves reexamining the decisions made in the past and using the input of the scientific community to evolve, upgrade, and improve data collection and resiliency at the field sites. Successes to date include improvements in flexibility and resilience for aquatic infrastructure designs, improved engagement with the scientific community that uses NEON data, and enhanced methods to deal with obsolescence of the instrumentation and infrastructure across the observatory.

  • This study investigated 62 nested quadrat plots of Jinaksan to identify community classification and changes of the vegetation by using the phytosocial method and analyzed importance values. Vegetation types were classified into 8 communities: Quercus mongolica community, Q. variableis community, Q. aliena community, Pinus densiflora, Q. acutissima, Zelkova serrata, Carpinis laxiflora, and C. tschonoskii. The significance value was highest in Q. mongolica (62.75) followed by P. densiflora (55.16), Q. variabilis community (25.03), Z. serrata (22.17), Q. aliena (18.30), Prunus serrulata var. pubescens (16.86), C. laxiflora (13.25), Q. acutissima (10.72), C. tschonoskii (10.08), Q. serrata (8.02), Fraxinus sieboldiana (6.93), Acer pseudosieboldianum (6.73), and Styrax obassis (5.73). Quercus mongolica displayed a stable distribution pattern, presenting a reverse J-shaped curve from the diameter at breast height (DBH) analysis, and it was judged that current state would be maintained for a certain period. In addition, P. densiflora is expected to dominate for the time being and Quercus species are expected to gradually decrease.

  • The use of attitude as a psychological concepts dates back to 1918(Thomas and Znaniecki). Assessment of attitudes has been conducted by a number of researchers since then in a wide range of contexts: religion, government, industry, community interrelations, and education; and sociology and psychology. In science, the number of research summaries and meta-analyses points to the significance of the concept of attitude toward science. However, in spite of the wide spread use of attitude assessment in science, many of the existing instruments have severe limitations. Those limitations serve as the rationale for the construction of a new instrument to assess attitudes toward science The term "attitude" and "science" are somewhat ambiguous, taking on different meanings for different people in different contexts. Very often an assessment includes several dimensions of attitude and, therefore, provides no clear idea of what was really measured. As a result there is no consistency with respect to the construct among attitude instruments. To clarify this issue, Gauld(1982), Munby(1983a, 1983b), Blosser(1984) and Haladyna and Shaughnessy(1982) offer some guiding descriptions. Attitude as it relates to science is divided into two areas-scientific attitude and attitude toward science. Scientific attitude refers to a particular approach a person assumes for solving problems, for assessing ideas and information, and for making decisions. It includes such scientific methods and predispositions as objectivity, suspended judgement, critical evaluation, and skepticism. Munby(1983a, 1983b) characterized scientific attitude as thinking as scientists do, that is, acting on evidence in a disciplined way. Attitude toward science. on the other hand, may address scientific attitudes, scientists, scientific careers, methods of teaching science, scientific interests, parts of curriculum, or the subject of science in the classroom (Blosser,1984). It may refer to belief about processes, theoretical products, technological products, or the science-technology relationship (Munby, 1983).

  • Researchers in Korea and elsewhere have carried out a wide variety of important research activities in their respective fields, producing valuable research results. For such diverse research results to be shared and exchanged among researchers working in the same discipline and research subject there needs to be a community environment based on free utilization of information. Against this backdrop, this study seeks to classify and reprocess the reference/factual content owned by the KISTI (Korea Institute of Science and Technology Information), a state-run distributor of information on science and technology, by the different research subjects. It also seeks to develop and provide a community model based on the concepts of open archiving and open access for the researchers specialized in the related fields of research. This community model is developed focusing on the research results from the field of bioscience, where the most extensive studies are currently being conducted. To develop the community model, this study: (a) surveys the current status of the content owned by KISTI; (b) analyzes the patterns and characteristics of biological scientific content among the KISTI-owned content; and (c) designs a web platform where researchers can freely upload/download research results.

  • 하나의 학문이 독립된 학문 분야로 성장하기 위해서는 그 학문 집단의 구성원들이 공통으로 이해하고 공유하는 가치기준(패러다임 : paradigm)이 있어야 하고 어떤 독자적인 학문체계(정체성 : identity)가 정립되려면 관련학회의 학문연구 활동을 통한 경쟁으로 새로운 패러다임을 구성하고 학문의 정체성이 확립되어야 하므로 정치학, 경제학, 심리학 등 분야에서는 이를 위한 노력이 어느 정도 이루어지고 있으나 소방학 분야에 있어서는 학문의 공동연구를 위한 학회의 활동은 물론, 학자 간 학문의 교류 연구가 미미하여 새로운 학문의 패러다임으로 자리 잡지 못하고 있는 실정이다. 따라서 본 연구에서는 이러한 문제의 근원을 파악하여 한국 실정에 맞는 소방학의 학문적 패러다임 구성과 정체성 확립의 방향을 제시하고자 한다.

  • 과학적 설명은 과학자의 과학적 실행에서 추구하는 주요한 목표이며 과학교육 과정 문서에서도 학생의 과학적 설명 구성 능력을 주요한 목표로 포함하고 있다. 따라서 그 의미를 명료화하는 것은 과학교육 공동체에서 중요한 문제이다. 이 논문에서는 주제 범위 문헌 고찰 방법을 사용하여 '과학적 설명'에 대한 3가지 관점을 추출하고 각각에 대해 고찰하였다(연역-법칙적 설명 모델, 확률론적 설명 모델, 실용적 설명 모델). 그리고 문헌 고찰 내용을 바탕으로 과학적 설명이 과학교육에서 사용하는 다른 개념들, 즉 '기술', '예상', '추론', '가설', '논증'과 어떤 점에서 유사하고 어떤 점에서 구분되는지 논의하면서 이러한 용어들의 의미를 구분하여 사용하는 것이 과학교육 연구와 실행에서 중요하다는 점을 주장하였다. 또 산물로서의 '과학적 설명'과 의사소통으로서 '과학적으로 설명하기'가 차이가 있음을 지적하고, 과학 교육과정의 성취기준 진술 방안, 학생의 과학적 설명 구성을 돕는 방안, 학생의 과학적 설명하기를 돕는 방안을 몇 가지 제안하였다. 예를 들어, 세 가지 과학적 설명 모델에 따라 각각 중요하게 고려해야 할 요인들을 구분하여 정리하고, 그러한 요인을 고려한 과학적 설명을 위한 과학 학습활동 사례를 제시하였다. 본 연구에서의 논의가 과학적 설명과 관련된 과학 학습에서 좀 더 분명하게 학습 목표를 설명하고 그에 따라 보다 적절한 학습활동을 설계하는 데 도움이 되기를 기대한다.

  • This study was conducted for clarifying distribution and characteristics of marshy Ericaceae plants on Mt. Changbai in China. The marshy Ericaceae plants in wetland of Mt. Changbai were investigated on about 1400 m altitude. This region is various developmental wetlands and vegetation mixture of needle-leaf trees and broad-leaf trees. This region also is start point of the coniferous forest zone in Mt. Changbai. As results of these researches, L. palustre var. diversipilosum and L. palustre var. decumbens populations were investigated in Larix olgensis var. amurensis community. R. lapponicum subsp. parvifolium var. parvifolium community appeared as a typical community. Environmental conditions of L. palustre var. diversipilosum and L. palustre var. decumbens populations' habitats are more soil humidity and shade condition. R. lapponicum subsp. parvifolium var. parvifolium community habitat, however, has more deposits and humidity condition. Therefore when the plants were cultivated, we should recognize the growth condition such as maintenance of humidity and control deposits. The flora of marshy Ericaceae species habitats was investigated as 28 families, 49 genera, 45 species, 14 variety, 1 forma, 1 sub-species, and total 61 taxa.
