Implementing a rural revitalization strategy will help spread traditional culture and promote the sustainable development of traditional handicrafts. Batik is a traditional handicraft made by residents in China's minority areas in their daily lives. This study was conducted because of a lack of objective methods for evaluating related project plans. This study was conducted to develop an index for the sustainable development of functional traditional batik production. This study had three major parts. The first part was a literature review that investigated sustainable and traditional batik dyeing and a field investigation carried out in Shitou Village, Danzhai County and Danzhai Paimo Village, Anshun, Guizhou to identify the factors that influence traditional batik production. The second part identified the factors identified in previous research that affect sustainable, traditional batik production and the projects executed to do the same. The third part was a survey conducted using the Delphi method. The results were analyzed, producing 10 influencing and 23 detailed factors that affect traditional batik production. Future research in this area should draw on various disciplines, investigate the direction in which traditional batik production is developing, and determine how to promote the sustainable development of other traditional handicrafts.

The purpose of this study is to analyze how the contents of education for sustainable development are reflected in the middle school environment curriculum revised in 2007, and to propose how to integrate content for improving sustainable development education. For this, I analyzed the 2007 Revised Environment Curriculum for Middle Schools by using social network analysis which is the useful methodology to understand the relations of contents. Social Network analysis is a useful tool to excavate the forms of structure or relationship and to explain the characteristics of the system that arise through relationships or to explain the units composing the system. When sustainable development education was examined from 3 points of view, it included environmental sustainability, economical sustainability, and social sustainability. I used the 2007 Revised Environment Curriculum for Middle Schools and manual of curriculum for analysis. The results are 1) The biodiversity conservation and energy efficiency have taken most important positions. 2) In case of economical sustainability pillar, sustainable production had been emphasized. 3) In the case of the social sustainability pillar, health improvement are considered significant. 4) The efforts of trying to approach sustainable development education as an integrated curriculum is week. Integrated themes based on the results were developed. Five main themes were the energy and climate change, water resource and environmental pollution, sustainable village and sustainable food production, sustainable city and sustainable production, sustainable tourism and biodiversity. I hope these could function as theme of integrated-content. Based on the results of study, I propose joint researches on scope of sustainable development for environmental education.

This research endeavors to explore the enhancement of workforce economic efficiency through the application of nanotechnology, focusing on its economic implications. The findings of this investigation reveal that in recent years, surging global population growth and escalating demands for products and services have led to excessive resource consumption, resulting in adverse environmental consequences and altering environmental conditions-a phenomenon referred to as the economic growth dilemma. Entrepreneurs and economic stakeholders have begun to recognize the importance of sustainable development and the integration of environmental considerations into the production of goods and services. Within this context, knowledge-based economies have emerged as a driving force for sustainable business practices, particularly in the realm of nanotechnology. The integration of nanotechnology across various industries, including pharmaceuticals, agriculture, environmental management, and the chemical and petroleum sectors, as well as energy distribution, has yielded remarkable results. Consequently, this research aims to investigate the application and integration of nanotechnology in environmentally friendly silver nanoparticle production within select industries. Subsequently, it will examine the far-reaching implications of nanotechnology on economic growth and sustainable development.

The purpose of this study is to compare and analyze the educational philosophy, goal, method, content, and environment of ecologically-oriented alternative elementary schools and suggest several practical methods for alternative education. Both ecologism and alternative education pursue sustainable values. The educational content of ecologically-oriented alternative elementary schools, analyzed from the view of sustainable development, focuses most on the natural resources, biodiversity, and sustainable food production, and also include human rights, peace and security, unification, cultural diversity, and health food in terms of the social sustainability and sustainable production and consumption concerning economic sustainability. This study should help environmental education become establish its possibility and position as alternative education and be recognized of its educational value. Furthermore, based on the cases of ecologically-oriented alternative elementary schools that are becoming 'garden of environmental education' as sustainable development education, it should lead to 'education communicating with environmental education at schools'.

The Netherlands produce more than 11 million tonnes of milk per year, and approximately 60% of the milk is exported. Dutch milk production is five times higher than that of Korea, even though Korea comprises a land area three times greater than the Netherlands. Upscaling and intensification have characterized the Dutch way of dairy farming since 1960, and adverse effects of the intensification of dairy farming became evident from the late 1970s and early 1980s onwards. The transition toward a more sustainable farming system is a central element of the Dutch agenda for the reconstruction of the livestock production sector. The environmental problems in Dutch dairy farming in the 1980s have led to the establishment of the experimental dairy farm "De Marke" which aims at improving the utilization of fertilizers and feeds, through minimizing nutrient requirements, maximizing the use of nutrients in organic manure and homegrown feeds, and through the targeted use of fertilizers and feeds. 85 cows at "De Marke" produce 720 tonnes of milk per year, using 55 ha of pasture in a sustainable manner. That means, 150,000 ha of pasture are required to produce 2 million tonnes of milk, which the current milk production of Korea. It is urgent to provide sufficient pasture for sustainable milk production in Korea, and primarily the transition to pasture of surplus rice paddies, resulting from of a decrease in rice consumption, should be considered.

The use of low-cost substrates represents one key issue to make single cell oil production sustainable. Among low-input crops, Arundo donax L. is a perennial herbaceous rhizomatous grass containing both C5 and C6 carbohydrates. The scope of the present work was to investigate and optimize the production of lipids by the oleaginous yeast Cutaneotrichosporon curvatus from undetoxified lignocellulosic hydrolysates of steam-pretreated A. donax. The growth of C. curvatus was first optimized in synthetic media, similar in terms of sugar concentration to hydrolysates, by applying the response surface methodology (RSM) analysis. Then the bioconversion of undetoxified hydrolysates was investigated. A fed-batch process for the fermentation of A. donax hydrolysates was finally implemented in a 2-L bioreactor. Under optimized conditions, the total lipid content was 64% of the dry cell weight and the lipid yield was 63% of the theoretical. The fatty acid profile of C. curvatus triglycerides contained 27% palmitic acid, 33% oleic acid and 32% linoleic acid. These results proved the potential of lipid production from A. donax, which is particularly important for their consideration as substitutes for vegetable oils in many applications such as biodiesel or bioplastics.

We consider a reverse supply chain with a production facility and a recovery facility, and address the joint control of production and disposal decisions for sustainable operations. Demands are satisfied from on-hand inventory of serviceable products, replenished via manufacturing or remanufacturing. Sold products may be returned after usage and each returned product is disposed of or accepted for recovery. Accepted returned products are converted into serviceable products after remanufacturing process. Formulating the model as a Markov decision process, we characterized the structure of the optimal production and disposal policy as two monotone switching curves under a special condition. Three types of heuristic policies are presented and their performance is numerically compared.

송이(Tricholoma matsutake)는 인공재배가 불가한 임산물로 노동 이외의 투입 요소가 적은 반면 가격이 높아 산촌 주민의 수익 증대에 큰 역할을 해왔다. 이러한 송이의 특성은 과도한 채취로 이어져 송이 자원의 고갈이 염려되는 상황이다. 송이의 지속 가능한 생산 전략을 제시하기 위하여 송이채취업의 생산함수와 송이의 성장함수를 추정하였다. 두 함수 추정에 필요한 정보의 제약을 고려하여 최대 엔트로피기법을 활용하였다. 2005년부터 2011년까지 송이의 생산량과 노동 투입량만으로 송이채취업의 생산함수와 송이의 성장함수를 도출한 것이다. 연구 결과, 송이 생산량은 노동 투입보다 자원량에 영향을 더 받았으며, 노동투입 부문에서는 송이채취업을 전업으로 하는 임가의 생산에 대한 노동 탄력성이 송이채취업을 겸업으로 하는 경우보다 컸다. 송이채취업의 생산함수와 송이의 생장함수를 이용하여 송이의 지속가능한 최적 생산 조건을 도출하였는데, 최근 7년의 실제 송이 생산은 지속가능한 최적 생산수준을 만족하지 못하는 것으로 나타났다. 따라서 송이 생산이 지속 가능한 최대 수준까지 도달할 수 있는 송이 자원량이 되도록 지금의 송이 생산을 억제하는 것이 필요하다.

To develop sustainable management strategies for oyster farms in Pukman Bay, Korea, we estimated primary production using a numerical model. Because oysters are filter feeders, estimations of primary production (PP) are essential in developing management strategies. The daily PP ranged from 0.07 to 1.5 gC/$m^2$/d and showed significant spatial variations. The spatial distribution of PP was strongly associated with hydrodynamic features, and distinct patterns were observed in three different regions. In the inner bay, high PP was directly influenced by urban and agricultural sewage. The middle part of the bay had low PP, whereas PP in the outer area was high. PP was relatively low during the main oyster growth season, from late autumn to early winter. These findings represent important information for developing a management model for oyster farms in Pukman Bay.
