This study investigated whether there was a difference of the change in perspective of the nature of science depending on subjects of the history of science, after designing for two kinds of topics of role play programs based on the history of science to be transformed into a modern perspective. Before the history of science-role plays, the degree of the modern perspective was statistically no difference between group I(the atomic model transition-role play) and group II(the Mendeleev's periodic table-role play). However after treatment of the history of science-role plays for the each group, the degree of group I was higher than the degree of group II in the modern perspective. The results of this study indicate that the degree of changes into modern perspective of the nature of science by performing a history of science-role play may be depend on the subject of the history of science combined with the role play, and suggest the possibility that may be more effective to change the nature of science into the modern perspective, in case of performing of role play based on the history of science that includes the scientific knowledge established by a number of scientists with time series.

This study was compared to the differences in the habitat, species composition and community structure of revegetation and nature area in Korea. Plant number in plot of revegetation and nature area was 10.3 and 15.0 taxa, respectively, and coverage was 90.6 and 88.1%, respectively. Revegetation and nature area was very heterogeneous, due to low similarity index (0.38) and less common plants. Festuca arundinacea frequency (56.7%) was highest in revegetation area, and Oplismenus undulatifolius frequency (66.7%) was highest in nature area. Plant appearing of revegetation and nature area was 111 and 136 taxa, respectively. Herb appearing of revegetation and nature areas was 93 (83.3%) and 72 (52.9%) taxa, respectively, tree was 18 (16.2%) and 64 (47.1%) taxa, respectively. Plant communities of revegetation area was classified into Lespedeza bicolor, Indigofera amblyantha, Alnus sibirica, Festuca arundinacea, Eragrostis curvula, Miscanthus sinensis, Humulus japonicus, Setaria faberii, Rudbeckia bicolor, Pueraria lobata community. Plant communities of nature area was classified into Pinus densiflora, Quercus aliena, Quercus acutissima, Quercus variabilis, Quercus serrata, Castanea crenata, Pinus rigida, Robinia pseudoacacia, Populus tomentiglandulosa, Phyllostachys bambusoides community. Habitat, species composition and community structure of revegetation and nature area showed a large difference.

Nature of Science(NOS) has been a well-organized focus of science education and one of the key elements in defining and cultivating scientific literacy for more than a century. In recent years, a specific description of NOS, which is often known as 'the consensus view of NOS', has become very influential and has gained ready acceptance as an arrangement for both curriculum building and research into understanding of NOS by students and teachers in many countries around the world. This study has two purposes; one is to review some debates and criticism on the consensus view of NOS which consists of a list of sentences to describe nature of refined and general science, which have been heated up for the last few years by many prominent science education researchers, and the other is to consider alternative perspectives on NOS for the purpose of a new direction of NOS education. As a result of an investigation into such views as 'Teaching about NOS', 'Critical NOS', 'Critical Thinking-NOS', 'Whole Science', 'Features of Science' and 'Reconceptualized Family Resemblance Approach to NOS', some implications which focus on the generality and plurality of content knowledge of NOS based on current philosophy of science and sociology of scientific knowledge are suggested for the improvement of teaching and learning NOS.

This research has studied the physicochemical environmental factors and communities of epilithic diatom and phytoplanktons at Hongcheon river from December 2011 to September 2012. In case of TN, the result was hypertrophic, and for TP, it ranged from mesotrophic to eutrophic. As for BOD, Hongcheon river was rated level II or better, according to the water quality level; values were found to be below 3mg/L at most sites. Total of 83 and 114 taxa of epilithic diatom and phytoplanktons respectively, were found during the research. When assessed using the TSI, it ranged from oligomesotrophic to eutrophic. In case of DAIpo, it ranged from 64.1 to 99.5, and TDI ranged from 51.5 to74.0. These results signify good water quality, level B or better, for Hongcheon river. P-IBI was rated moderate to low, which showed higher pollution than other indices. Among the biological water quality measures analyzed in the Hongcheon river study, DAIpo best matches TDI and BOD, while TDI showed greater pollution. Therefore, P-IBI appears to be inappropriate when assessing the domestic small rivers and lakes.

Natural forms could be ultimate visual expression power that affects on the industrial design. The rule of power in nature as nature formal characteristics have a direct influence and can be also applied to productional and artificial form. All organic forms and structures in nature have unique form and shape to be self controlled and good in order. Such an order in nature comes from regular and ratio principles which has aesthetical order by mathematics. The specialty of beauty in nature can be revealed not only visual form but also the ratio, balance and rhythm of structural principles. As we examine the aesthetic source, embodied some object can be developed into basic principles. Furthermore, through this study we can find out that the form theory in nature forms share the quality attribute with geometrical form to be shown in industrial product design. In this context, this study aims to make dear visual quality of organic form and structure that is immanent in nature about a form as formative principles of industrial product design, the significancy of this study is to prove the application into functional and structural form of product design.

The purpose of this study is to gain an understanding of scientifically gifted students' views on the nature of science. A multiple-choice format questionnaire was administered to 237 Korean 10th, 11th and 12th graders at the Korea Science Academy. The differences and similarities by gender and experience of R&E program on the students' views of the nature of science were investigated. The questionnaire developed by Lim(2004) was implemented for this investigation. We found that the majority of scientifically gifted students had highly possessed the tentativeness of scientific knowledge. The students who experienced R&E program have relatively high apprehension of scientists' motivation for researches and activities in social context compared to the students who did not experience an R&E program. Scientifically gifted students had relatively high apprehension that government should not control researches of scientists and relatively low apprehension of social responsibilities of scientists comparing to general high school students. The experience on R&E program was identified as a factor to effect changes in the students' views on the nature of science. The study has implications for the development of gifted program and curriculum such as running and assessing R&E program, and also the pre-service preparation of science teacher, teacher education reformat in both the practical and the policy levels.

This paper examines the conceptual shift of wilderness and its legacy to the contradictory view of nature in landscape architecture tradition. In hunting and gathering societies, there was no dichotomy between the cultivated environment and wilderness. 'Wilderness' is a word whose first usage marks the transition from a hunting-gathering economy to an agricultural society. We can identify two archetypal responses to wilderness: classical and romantic. In the classical perspective, wilderness is something to be feared-an area of waste and desolation. The conquest of wilderness and the creation of usable places is a mark of civilization. For the romantics, in contrast, untouched wilderness has the greatest significance; it has a purity that human contact tends to sully and degrade. Wilderness for the romantics is a place to revere, a place of deep spiritual significance, and an object of aesthetic experience. In the Western world, the classical position predominated until the last two hundred years when the romantic concept began to gain more ground. The shift was made possible by the change in the way nature is understood. Modernity and modern science objectified nature. The transition of the concept of wilderness exemplifies the objectification and pictorialization of nature. Wilderness in the modern era is not different from the pastoral landscape which can be controlled by landscape architects.

The beauty of Korean architecture is in its natural beauty. Traditional residence of Korea is architecture that expresses modesty that is embraces the nature. Hanok is designed based on understanding of the nature and responding to it. For this reason, Hanok is a nature-friendly residential space. There are many unique traits of Hanok and one of them is that it is built based on scientific principles. Hanok, without using modern technology and machines, utilizes effectively the natural environment and the climate, e.g., the sun and the wind. Hanok, based on Korea's geographical condition and climate characteristics, have produced a variety of residential houses. The principle of Hanok is not to challenge the nature but embrace and accept it. Furthermore, in Hanok is embedded Korea's traditional philosophy and ideas and it is not simply a simple residential space but also a place for meditation and spiritual training. As the time passes, there are more researches are being done to enhance health in addition to traditional role of protection and convenience. Accordingly, more efforts are being made to bring the nature into human life. Hanok, the traditional residential form of Korea, has environment-friendly architecture and characteristics that could promote human health and enhance our life. Therefore, the nature-oriented philosophy and environmental elements of Hanok should be more systematically studied to take advantage of its architectural advantages and create healthier modern residential culture.

This study was performed to identify the tendency and benefits of outdoor recreation in rural areas. The preferences and importance of the benefits of outdoor recreation activities in rural areas were simultaneously compared and analyzed through the discussion of a four quadrants portfolio map using importance-performance analysis. The social benefits in quadrant i had the characteristics of 'sharing nice experiences with others', 'having contact/interchange with others', 'colleagueship/helping each other', 'being together with friends', and 'making new friends.' These social benefit types were perceived as very important characteristics, but the real level of achievement was rather low. Thus it seems necessary, in the process of program development, to apply the social benefit types to the characteristics of the participants. The experience of nature and relaxation benefits in quadrant ii had the characteristics of 'relaxation and recreation', 'understanding nature', 'nature experience', 'getting away from everyday life', and 'experiencing new things.' These benefits and experience of nature were regarded as very important characteristics by the participants in outdoor recreation and, at the same time, their real achievements were highly recognized, thus they seemed to be proper types for the goals involved in developing an outdoor recreation activity program in rural areas. The personal and challenge benefits in quadrant iv had the characteristics of 'training of mental ability', 'improvement of self-esteem', 'fitness', 'increase in determination', 'possible danger', 'achievement', 'excitement', and 'adventure.' These benefits had less importance to the participants, but had relatively high achievement, thus it might be important to make further suggestions for the direction of development according to the participants' tendency, seasons and facilities.

In nature, plant diseases, insects and parasites (hereafter called as "pest") must be co-survived. The most common expression of co-survival of a host crop to the pest can be tolerance. With tolerance, chemical uses can be minimized and it protects environment and sustains host productivity and the minimum pest survival. Tolerance can be applicable in all living organisms including crop plants, lifestocks and even human beings. Tolerant system controls pest about 90 to 95% (this pest control system often be called as horizontal or partial resistance), while the use of chemicals or selection of high resistance controls pest 100% (the most expression of this control system is vertical resistance or true resistance). Controlling or eliminating the pests by either chemicals or vertical resistance create new problems in nature and destroy the co-survial balance of pest and host. Controlling pests through tolerance can only permit co-survive of pests and hosts. Tolerance is durable and environmentally-friend. Crop cultivars based on tolerance system are different from those developed by genetically modified organism (GMO) system. The former stabilizes genetic balance of a pest and a host crop in nature while the latter destabilizes the genetic balance due to 100% control. For three decades, the author has implemented the tolerance system in breeding maize cultivars against various pests in both tropical and temperate environments. Parasitic weed Striga species known as the greatest biological problem in agriculture has even been controlled through this system. The final effect of the tolerance can be an integrated genetic pest management (IGPM) without any chemical uses and it makes co-survival of pests in nature.in nature.
