This study explores the effective visual resources in the “regularity in chemical reactions” unit of ninth grade science textbooks (2009 revised version). The frequency and role of visual resources were initially examined, and the students’ perceptions of visual resources were investigated. The results of the analysis represented the learning material presentation (68%), motivational categories (14%), guide to inquiry procedures (9%), and inquiry results and summaries (8%). According to the investigation of the students’ perceptions of visual resources, the most effective visual resource for motivation is a photograph depicting physical and chemical changes, such as in bread baking and the most effective for learning material presentations in mass conservation, definite proportion, and stoichiometric concept units were a cartoon, graph, and formula representing stoichiometric phenomena, respectively. The most effective resource for guide to inquiry (experimental) procedures were photographs of both instruments and sequential experiment processes; and in the inquiry results and summary category, incomplete tables and graphs for students to work on themselves. The aims of this research are to increase the usefulness of visual resources in the teaching-learning activity and provide informative supplements for the development and improvement of visual resources, according to the students’ perceptions.

Over the world, social demands and concerns of energy and resource depletions and environmental conservation have resulted in many researches and applications on sustainable development and construction. In order to support these demands and concerns, international green building certification systems such as LEED(Leadership in Energy and Environmental Design) and BREEAM(Building Research Establishment Environmental Assessment Method) were developed. In Korea, the green building certification system was introduced in 2000 and widely applied to all types of new buildings in order to induce the diffusion of sustainable buildings on May, 2010. This paper investigates the importance of assessment criteria on multi-unit apartment projects among certification rating systems using the AHP(Analytic Hierarchy Process) method and suggests a new direction on certification assessment standards. For applying the AHP method, the survey of staffs in green building certification consulting companies and architectural design companies was conducted via e-mail. As a result, criteria like energy, indoor environment, land use, pollution control, and ecological environment among 9 main ones turned out important on assessing green building certification at multi-unit apartment projects, while criteria like water resource, transportation, maintenance management, and material and resource did relatively unimportant.

Adding chemical additives in bamboo paper making procedure in China became common in last decades to increase productivity. Supply of repair paper for paper based artefacts became more and more difficult due to this tendency. Furthermore, stains and spots on paper which happen to appear during dying procedure make it difficult to use modern bamboo paper for repair treatment. In this research, lime fermentation and sun bleaching were main elements which affect texture and color of paper. Impurities, however, add some effects on paper quality. Less thouroughly washed raw materials after fermentation also affects texture of paper substrate. One most significant impurity is lime. Minimum residue of lime can make stains and spots after dying. Reproduction of white bamboo paper would become useful resource in various conservation treatments as a repair paper, and also, for reproduction of paper woven painting. However, further research to improve quality at early stage of paper making procedure in China required.

The study is conducted to establish the National Protected Areas Integrated System(NPAIS) which includes National Protected Areas(NPAs) and other conservation measures in terms of effective ways for biodiversity conservation. Additionally, it is carried out to evaluate progress toward quantitative expansion goals in Aichi biodiversity Target 11. The NPAIS consists of NPAs and other effective area-based conservation measures(OECMs). There are two different types of OECMs. OECMs type I, including water-source protection Areas(WPA), riparian zones(RZ), fishery-resource protection zones (FPZ), and urban natural park zones(UNPZ), is a potential protected area which is recommended to be incorporated into the NPAs for effective management. OECMs type II means development restriction zones(DRZ), natural recreation forests(NRF), and buffer zones for Korea national arboretum(BKNA). As a result of evaluating the quantitative expansion goals of the NPAIS, terrestrial and inland water protected areas exceed 17% of the quantitative goal in Aichi biodiversity Target 11. The larger the area of individual OECMs and the lower the degree of overlap with NPAs, the higher the contribution of them to the terrestrial and inland water protected areas. DRZ contributes to enlarge more than 3% of quantitative expansion. And RZ and NRF contribute more than 1%. The marine protected areas are expanded by $1,425km^2$ through FPZ, but the expanded area is very small as comparing with the total marine area. It adds only 0.321% to the quantitative expansion. The rest of OECMs also has very poor quantitative expansion contributions in the marine area. Consequently, the NPAIS is effective for quantitative expansion of land areas, but not for marine areas.

This study is on system building and model case study to establish a new framework of "The Wild and Scenic Rivers System" and to apply this to Korean rivers. The Wild and Scenic Rivers System of the U. S. , which had become law in 1968 for establishing wild scenic and recreational river areas, was investigated. The techniques of two American case studies about the National Wild and Scenic Rivers System designation were investigated and synthesized, and study process was adjusted to Korean river system. Additionally, pilot study was carried out by the method and results were as follows : 1) In the American Wild and Scenic Rivers System, each river was evaluated based on eligibility criteria for designation, such as remarkable scenic, recreational, fish and wildlife, cultural or other ecological values. Segmented river areas were classified into three or four grades and management plans were prepared accordingly. 2) The management of rivers in Korea has emphasized on the flood control and water resources management up to the present, and now takes a growing interest in water quality. But it has been concerned very little with wild and scenic resources conservation of river corridors. It is strongly recommended to build Wild and Scenic Rivers System in Korea for rational management and conservation of the valuable natural resource. 3) Suggested evaluation criteria for the Korean Wild and Scenic Rivers System were wildness, wildlife and plants, hydrology, scenic quality, and historical and cultural resources. The river areas may be graded into four : Positive conservation area(I), Negative conservation area(II), Negative development area(III), Positive development area(IV). Management guidelines were proposed for each grade. 4) To test the applicability of the approach, one of the major tributary of the Han-River was selected for pilot study. The result showed that the evaluation and grading system worked well. Finally, it is recommended to incorporate the Wild and Scenic Rivers System into Korean national park system, and to amend the Korean National Park Act to enable this.

Integration system of conservation ecology, ecosystem management and land planing in landscape scale is major principle strategy for national management system of environmental resource and biodiversity. Current conservation strategy is concerned with not only population and habitat level but also ecosystem and landscape level. In especially, ecological networking to link core areas or major habitat patches is most eminent and emerging issue in European Union (EU) and North America. Moreover, the promotion of national ecological network system in EU is focused on national cooperation to construct ecological corridor for key habitat that distributed in many countries. Integrating landscape ecology into conservation ecology and restoration have important role to stimulate the network system in regional and national level. In this review paper, comprehensive and necessary considerations arisen from the view of landscape ecology were discussed for the present situations of wildlife conservation and management in Korea compared with other countries. Especially, the conservation strategy and policy of biodiversity were addressed in broad sense including habitat protection, legal approaches, and ecological network programs. Finally, a national ecological network system was suggested for environmental policy in Korea in global consideration after the Korean Unification.

The Ministry of Agriculture, Food and Rural Affairs of Korea(MAFRA) has launched 'The Korea's Important Agricultural Heritage System(KIAHS)' in 2012 to conserve the regional heritages of agriculture and its significance. The effort has achieved in designation of seven KIAHS and two Globally Important Agricultural Heritage System(GIAHS). The policy environment has evolved a great deal since the launch of KIAHS. The study has evaluated the current policy condition of KIAHS and analyzed the shift on the KIAHS policy environment. The study has concluded the policy environmental changes as follows; insufficient Agricultural Heritage(AH) resource development, intensified interests in AH monitoring system, anticipated rural developments thru AH utilizations, under-budgeted AH conservation and management measures. The study has suggested the following based on the evaluation; establishment of AH Conservation and Management System as the conservation and management policy of AH, ease the designation standards for AH, obliged monitoring system for AH, developing AH brand, budget increase for AH conservation and management system. The suggest policy will successfully assist the further development and designation of AH. Farmers in AH area can maintain farm activities thru the conservation, management and utilization of AH, inheriting the important agricultural heritage for the future generation.

Background: Poultry breeding has increased by 306% in Korea, inevitably increasing the production of manure which may contribute to environmental pollution. The nutrients (NP) in the manure are essential for crop cultivation and soil fertility when applied as compost. Excess nutrients from manure can be accumulated on the land and can lead to eutrophication. Therefore, a nutrient load on the finite land should be calculated. Methods: This study calculates the nutrient production from Korean poultry by investigating 11 broiler and 16 laying hen farms. The broiler manure was composted using deep litter composting while for layer deep litter composting, drying, and simple static pile were in practice. The effect of weight reduction and storing period during composting was checked. Three weight reduction cases of compost were constructed to calculate nutrient loading coefficients (NLCs) using data from; i) farm investigation, ii) theoretical P changes (${\Delta}P=0$), and iii) dry basis. Results: During farm investigation of broiler and layer with deep litter composting, there was a 68 and 21% N loss whereas 77 and 33% P loss was found, respectively. In case of layer composting, a loss of 10-56% N and a 52% P loss was observed. Drying manure increased the P concentrations therefore NLCs calculated using dry basis that showed quite higher reductions (67% N; 53% P). Nutrient loss from farm investigation was much higher than reported by Korean Ministry of Environment (ME). Conclusions: Nutrients in manure are decreased when undergo storing or composting process due to microbial action, drying, and leaching. The nutrient load applied to soil is less than the fresh manure, hence the livestock manure management and conservation of environment would be facilitated.
