Recently, new concept and paradigm of 'Environmental Sustainability' is taking a growing interest in environmental planning and design. This study is to establish the environmental sustainability principles, based on the concept of ESSD, and to develop the evaluation model of environmental sustainability for korean rural housing estates. A sustainability indices system, which is composed of 5 principles, 16 categories, an 37 estimation items, was finally established. Five principles of environmental sustainability for rural housing estate were. 'Sustainable Land Use', 'Interdependence of Men and Nature', 'Ecological Principles and Diversity', 'Efficient use of Energy and Recycling', and ' Minimizing Environmental Pollution'. And weighting values of each indicators, such as estimation items, categories, and principles, were estimated, based on the result of AHP etc. The questinnaire survey was conducted for experts of four related major fields. Finally, the validity and reliability of the sustainability indices system were verified.

Climate change is strongly threatening the performance of agricultural reservoirs, which are instrumental in ensuring uninterrupted water supplies for rice cultivation in Korea. In this study, various performance indices were derived and overall sustainability of the 400 agricultural reservoirs was evaluated in the context of climate change trends during 1973-2017. Rice crop evapotranspiration, irrigation water requirements, runoff generation in the upstream watershed, and volumetric evaporation losses were plugged into a water balance model to simulate the reservoir operation during the study period. Resilience, reliability, and vulnerability are the three main indicators of reservoir performance, and these were combined into a single sustainability metric to define the overall system credibility. Historical climate data analysis confirmed that the country is facing a gradual warming shift, particularly in the central and southern agricultural regions. Although annual cumulative rainfall increased over the last 45 years, uneven monthly rainfall distribution during the dry and wet seasons also exacerbated the severity and frequency of droughts/floods. For approximately 85% of the selected reservoirs, the sustainability ranged between 0.35 to 0.77, and this range narrowed sharply with time, particularly for the reservoirs located in the western and southern coast regions. The study outcomes could help in developing the acceptable ranges of the performance indices and implementing appropriate policy and technical interventions for improving the sustainability of reservoirs with unacceptable ranges of the performance indices.

PURPOSES : This paper aims to improve the evaluation method of the Level of Service(LOS) for urban streets presented by the current Korean Highway Capacity Manual(KHCM) and suggest its utilization plan as a part of the methods to evaluate the sustainability of a transportation policy. METHODS : This paper carried out a research in 3 steps to develop a new evaluation method. First of all, this paper reviewed the previous studies related to the LOS of urban streets and the socially requested items for a sustainable transportation system. Then this paper derived an index and weight through expert questions to select an evaluation index. Lastly, this paper compared the results according to the existing evaluation methods with the new evaluation methods through case studies. This paper used an Analytic Hierarchy Process(AHP) for importance analysis and weight selection between new evaluation items and indices, and applied a Grey System Theory(GST) for a synthetic and integrated evaluation between the selected evaluation indices. RESULTS : As a result of evaluating the LOS according to the existing evaluation methods and the integrated evaluation methods using a GST through case studies, it was analyzed that new methods' results are less than or equal to the existing evaluation methods; and as a result of applying a weight between evaluation indices according to AHP, it was noticed that the total score seems to rise more when the LOS in the existing evaluation is calculated lower. It was analyzed that the LOS calculated by reflecting the newly established evaluation items and the importance between indices in this study has difference from the LOS of the existing urban streets. CONCLUSIONS : It is expected that this evaluation method can diagnose the current conditions when establishing a future sustainable traffic system and can be used for the measurement of the sustainability effects of the improvement plans and so on.

이 논문의 목적은 한국의 환경정책을 간략하게 개관하고 한국의 환경적 지속가능성을 잘 알려진 지속가능성지수에 비추어 평가하고 동아시아 주요국들과 비교해 보고자 하는 것이다. 한국의 환경정책에 대한 개관과 평가는 주로 정부의 "Green Vision 21", "Green Korea 2005", 그리고 OECD의 Environmental Performance Review : Korea 2006에 나온 내용을 근거로 한 것이다. 한국의 지속가능성을 동아시아 다른 나라들과 비교한 부분은 EF, ESI, SPI, EVI 등 잘 알려진 환경적 지속가능성 지수를 인용하여 비교해 본 것이다. 그러나 이러한 지수들을 국가간 비교에 적용해 보려고 시도해 본 결과는 이들 지수들이 국가간 그리고 시점간 비교 가능성을 결여하고 있다는 것이었다. 그리고 이들 지수들은 지속가능성이란 개념을 충실히 반영하여 환경적 지속가능성을 측정할 수 있도록 구성되어 있지 않다는 점이 지적되었다. 그러므로 우리는 환경적 지속가능성의 개념을 비교적 충실히 반영하고 있다고 생각되는 세계은행이 제시한 'genuine saying'의 개념에 입각한 '지속가능량' 지수에 착안하여 이를 한국과 한국의 주요 무역대상국에 대해 계산하고 비교해 본 다음, 이 지수의 1985~1995년 기간중 변화 요인을 분석한 결과를 간단하게 제시해 보이고 그 함의를 설명함으로써 대안을 제시해보고자 하였다.

Sustainability index was calculated to determine the best management for rice productivity under long-term inorganic fertilizer management's practices. It is based on nutrient index, microbiological index and crop index related to sustainability as soil function. Indicators for calculating sustainability index were selected by the comparison of soil properties and rice response in paddy soil with fertilization. Total twenty two indicators were determined to assess nutrient index, microbiological index and crop index in order to compare the effect of different fertilization. The indices were applied to assess the sustainability with different inorganic fertilizer treatments such as control, N, NK, NP, NPK, NPK+Si, and NPK+Compost. The long-term application of compost with NPK was the highest sustainability index value because it increased nutrient index, microbial index and crop index. The use of chemical fertilizers resulted in poor soil microbial index and crop index, but the treatments like NP, NPK, and NPK+Si were maintained sustainability in paddy soil. These results indicate that application of organic and chemical fertilizer could be a good management to improve rice sustainability in paddy soil.

In the application of the ecosystem-based fisheries assessment Jeonnam marine ranching ecosystem, two fisheries, funnel fishery and trap fishery, were selected as target fisheries. Black seabream, Acanthopagru schlegelii, rock bream, Sebastes inermis, gray mullet, Mugil cephalus, were selected as target species for the funnel fishery, and conger eel, Conger myriaster, was target species for the trap fishery. For assessing indicators of four management objectives, that is the maintenance of sustainability, biodiversity, habitat quality and socio-economic benefits, indicators were selected considering the availability of data, which were 5 indicators for sustainability, 3 indicators for biodiversity, 4 indicators for habitat, 2 indicators for socio-economic benefit. The Objective risk indices for sustainability and biodiversity of two fisheries were estimated at yellow zone, medium risk level. The objective risk indices for habitat and socio-economic benefit were estimated at green zone, safe level. The species risk indices (SRI) were estimated at yellow zone. The fishery risk indices (FRIs) were estimated at 1.143 and 1.400 for funnel net fishery and trap fishery, respectively. Finally the ecosystem risk index estimated at 1.184.

This study aims to test the information content of sustainability reports issued by the most significant telecommunications companies operating in the Kingdom of Saudi Arabia (Stc, Zain, and Mobily), and their compatibility with the national sustainability standards issued by the Ministry of Commerce in the Kingdom of Saudi Arabia in light of the Kingdom's vision 2030, and its impact on the stock exchange indices of these companies. The event study methodology was used to study the impact of publishing sustainability reports on stock prices and the trading volume of these companies' shares in the Saudi stock market during the period from (October 2020 to March 2021). The results indicate a significant impact of the information contained in the sustainability reports on stock prices and trading volume in the stock market, and the importance of directing the company's management towards more disclosure of information about sustainability in its environmental, social, and economic aspects instead of focusing only on information related to the financial performance and economic activity of the company. This encourages the listed companies to disclose the sustainability of the financial reports and standardize the form in which these disclosures are prepared.
