Structure-typed cultural heritage, objects of preservation are positioned as one of the very important heritage in the nation, and the preservation of prototypical structures become influential in national development and against natural disaster. For this reason, Digital Close Range Photogrammetry has recently been diversely used. Despite its popular use, the measurement has limits that make it unsuitable for photographing precise cultural heritage situated at high mountainous terrain or where people can not approach easily. These high gigantic stone statues are among the preserved structure-typed cultural heritage. In order to supplement the limits, when using the measurement, a camera tripod with +30m, a ladder truck and a shore should be equipped, which means additional equipment leads to it being a waste of cost and time. In this vein, a device was developed in detail, using a RC Helicopter installed with a CCD video camera with ease of control, safety, equipment, carrying, movement and approach, then checked image shot by a wireless modem at real time and considered the economical efficiency without re-photographing. Next, the author digitized the images of the nationally designated structure-typed cultural heritage, used materials on their restoration as the third dimension in order to construct the integrated management-information system for cultural heritage. Through the above processes, this study can provide specific information on 3D images and 3D CAD sections of structured-typed cultural heritage for both the public and specialists on the web. Moreover, it suggests the foundation to restore the damaged cultural heritage in the future by aiming for their effective management and preservation.

In South Korea, Mine industries were encouraged to obtain the natural resource from 1960 to 1980. However, the depletion of natural resource and decreasing price have been caused by the voluntary closure of non-economical mines and a cut of their production since 1990. Harmful wastewater containing such heavy metals as iron, aluminum, arsenic, and cadmium are being discharged from abandoned pits and waste stone and tailing dumping sites following the closure of mines. Therefore, the objective of this paper suggests a policy of mine hazard prevention(PMHP) and method that allows the combination of new spatial data and as well as collected data on resources for the sustainable mine reclamation and management using EGIS/MGIS technique to develop an integrated plan and management techniques.

The purpose of this study is to consider for the introduction of the school eco-audit system as an educational method for sustainable development. First of all, the concept and objective of the education for sustainable development(ESD) are reviewed in order to advance a theory on school eco-audit system. ESD which under the premise of global inter and intra generation justice, resolves to address a mixture of ecological, economical and social aspects, as well as safeguarding limited resources and protecting the environment from pollution and energy. In order to effectively structure uncoordinated environmental activities carried out by schools, the introduction of school eco-audit system in Korea is suggested, which as the model for long-term development, has since been integrated into the school's programme. Activities related to waste, heating, electricity and water are run by a 'Management Team'. By combining all 3 fields of action - i.e. establishing basic organizational conditions, education, and individual ecological measures - the eco-audit proves to be the key to success. In particular, administration agency and method, institutional improvement are presented.

It is important to obtain real-time data from long-term monitoring of landfills and develop leachate leakage detection system for the integrated management of landfills. A novel real time monitoring system and early leakage detection system was suggested in this study. The suggested monitoring system is composed of two parts; (1) a set of moisture sensors which monitor the areas surrounding the landfill, and (2) a set of moisture and temperature sensors which monitor the landfill inside. For the assessment for landfills stabilization, real-time monitoring system was evaluated in dry and wet cell of pilot-site. In addition, the grid-net electrical conductivity measurement system was also suggested as early leakage detection system. In this study, the field applicability of suggested systems was evaluated through pilot-scale field tests. The results of pilot-scale field model tests indicate that the grid-net electrical conductivity measurement method can be applicable to the detection of landfill leachate at the initial stage of intrusion, and thus has a potential for monitoring leachate leakage at waste landfills.

As improving our standard of living, demographic change or industrial development, MSW that is closely linked to human behavior has been occurred much change. Notably, we usually have incinerated the combustible waste. In the process, they also emit a large amount of greenhouse gas that has directly affected the global warming and environmental pollution. Therefore, we need to make control system to manage future production and reduce generation of MSW. Thus this study analyzed the generation of MSW according to household members and floor area in apartment housing occupies the highest share. Then, we used both a correlation analysis and a regression analysis to make new estimation model of MSW generation. Based on this study, the results were used to suggest a method to efficiently handle MSW in the case of planning urban environment. Also, build a database to set up the integrated management system of MSW in the future.

Oship stream is located nearby south eastern coasts. This study was performed to find out waters quality modeling and then to predict water quality of Oship stream. Based on survey data, BOD, T-N, T-P calibration and verification result were in good agreement with measured value within mean coefficient variance(MSE) value, which were 13.9%, 9.0%, 26.5% and 19.5%, 12.0%, 16.5%, respectively. Sectional water quality predictions of the main stream of Oship stream are executed on the basis of the following cases 1) with sewage treatment of Dogye-eup 2) reduction of mine wastewater treatment of 80% in th basin. As a result, BOD, T-P improvement rates at down stream of Oship stream, case 1) were appeared 12.2%, 22.2%, case 2) maximum sulfate ion and conductivity reduction removal rate of Oship stream were 58%, 68%. The main pollution sources of Oship-stream were almost domestic wastewater and mine wastewater discharged from Dogye-eup which located in uppers stream. The large effects will appear after the construction of Dogye sewage water treatment plant which remove the organic matter and nutrients in these sewage water. The waste water from mine can not easily to treat for characteristics of effluence and economic problems. However, to achieve the goal of water quality in Oship-stream water system, treatments of those are necessary.

This article aims to describe the institutional structuring strategy of independent smallholders in accelerating sustainable economic development, by taking the example of the cow-coconut integration system (SISKA) problem in Sialang Palas Village, Riau. The method used identified stakeholders related to SISKA; the stakeholder's goals and interests, farmers' social and institutional bases, and self-help farmer socio-economic networks. First, identification of various factors through strengths, weaknesses, opportunities, and threats (SWOT) analysis techniques. Second, through the Modern Political Economy analysis technique. Third, imparting knowledge and skills to the farmers and village officials through a collective learning process in utilizing natural resource waste and social resources. The results showed that the farmer management strategy in the reform era started by clustering the interests of farmers. The dynamics of structuring group relations between the chairman and members with farmers outside the group are the basis for strengthening the local ideology of independence in the future. This institutional structuring strategy that focuses on access to farm power in the village decision-making process encourages a more integrated work of farmer organizations. The analysis above shows that the independent smallholder institutional engineering through regulation, organization, and resources are determined by the farmer household economic factors and the application of the value of local wisdom.

The purpose of this paper is to derive priorities and implications for the organic resource conservation policy in the livestock sector. We conducted a survey on the importance-performance of the organic waste resource reclamation of livestock sector using a 5-point Likert scale. The importance average for the resource recycling of livestock organic waste was 3.63 and the average of performance was 3.04. As a result of the IPA on livestock manure recycling measures, it is necessary to improve feed quality, establish a local recycling system, increase demand for compost and liquid, enhance customer linkages, and develop cost reduction technologies. It requires intensive support for promoting the spread of odor reduction technologies and integrated management of biomass. It is necessary to introduce mid- and long-term measures such as the revival of feed in tariff, promote by-product feeding, establish solid fuel process management standards, create hygiene safety standards, develop eco-beads and promotion of feed conversion. It is required to strengthen support for the development of odor reduction technologies and prepare consultative organizations among related departments, develop eco-friendly solid fuel technology, and support policies for renewable energy certification.

We analyzed the spatio-temporal distribution characteristics of water quality and phytoplankton communities in the Isa Stream systems (ISS) from Sangsa Lake to Suncheon Bay. Sangsa Lake showed relatively oligotrophic and mesotrophic conditions, but the freshwater and mixed brackish water zones showed more severe eutrophication than Sangsa Lake and Suncheon Bay due to the influence of industrial waste such as livestock waste. In terms of the phytoplankton community, the number of phytoplankton species was higher in freshwater and mixed brackish water zones than in Sangsa Lake and Suncheon Bay, but the cell density and Chlorophyll-a concentrations (Chl-a) were relatively high in Sanga Lake and Suncheon Bay. In particular, the mesotrophic species Fragilaria crotonensis and Asterionella formosa showed different dominance in the surface and bottom layers, and the influence of A. formosa was significant in the freshwater and mixed brackish water zones in spring and summer. However, Skeletonema costatum-ls, a eutrophic indicator species, dominated in mixed brackish water zones to seawater in autumn and winter. Thus, the severe eutrophication and rapid environmental changes in the ISS could seriously damage the coastal ecosystem in Suncheon Bay. These ecosystem changes are threatening in terms of conservation and management of the UNESCO Suncheon Biosphere Reserve and Yeoja Bay including Suncheon Bay, which recorded the first Ramsar wetland in Korea. Therefore, further research is needed to establish an in-depth management plan.

The purpose of this paper is to verify improvement of the basic quality of food resources and make the pork legs as the more advanced food products after taking special processing steps with the mixture of traditional medical herbs and hot water extracted coffee meal. The pH level of the pettitoes(Jokbal) showed the highest rate among the control group but it showed no statistical differences in the moisture content between the control and the pettitoes(Jokbal) processed with coffee waste extract as an additional component. In addition, the levels of crude fat and crude ash showed slight increases as the addition of the amount increase. In case of the proteins, however, tendency of slight was decreased but it was not significantly difference as the amount increases. The sodium rate in the pettitoes(Jokbal) was higher in the additional group than in the control group. Texture analysis showed a tendency of wide decrease in the hardness and chewiness depending on amount of the added coffee waste extract. On the other hand, as for the cohesiveness and springiness, there was no significant difference with the control group. In case of the lightness value, as the amount of added coffee waste extract is increased from 10% to 20% and 30%, the 'L' value was reduced significantly compared to that of the control. And the 'a' value was not significantly different compared to the coffee waste extract foil impregnated furniture control. But the 'b' values were significantly increased in accordance with the result of increasing the amount of control is at the lowest level. The result may come from the influence of coffee waste extract, which affects the color of the pettitoes(Jokbal). According to the sensory evaluation, the pork part with 10% of coffee waste extract showed the highest score in looking, chewiness, smell and preference, resulting in the improvement in quality of the pettitoes(Jokbal).
