In effort to estimate sustainability of the transportation sector, this study conducts a comparative analysis of methodology suggested for measuring greenhouse gas emission. There are two approaches proposed by the UN IPCC: 1) top-down approach (TDA) based on the amount oil sales, and 2) bottom-up approach (BUA) utilizing the velocity of moving source and traffic volume data. The subject areas for analysis were selected based on research results by the Korea Transportation Institute that evaluate traffic sustainability of each local government. Gwacheon-si being one of the top ranked areas in sustainability, and Anseong-si being ranked at the 7th level were analyzed. By the tier 1 methodology, Gwacheon-si and Anseong-si are estimated to create 74,813ton/yr, and 584,125ton/yr of the greenhouse gas emission, respectively. The tier 3 methodology, however, estimates Gwacheon-si and Anseong-si to create 91,462ton/yr, and 163,801ton/yr of the emission, respectively. Comparison of the two estimated emissions shows considerable differences; i.e., the tier 3 method over estimates Gwacheon-si's emission by 22.3% whereas it underestimates Anseong-si's greenhouse gas emission by the factor of about 3.5 compared to the emissions obtained from the tier 1 method. The result from this study implies that the traffic-sustainability-index based grade of each local government can be evaluated differently by the method adopted for measuring greenhouse gas emission.

Socio-technical systems are receiving growing attention as a core concept in the process of searching for proper solutions to sustainable growth. In this paper, we review the way for governing socio-technical transitions from a governmental perspective. Based upon the governance studies and transition research, we set social coordination and locus of transition pressures as transition contexts to differentiate transition policy governance. We propose four types of policy governance for sustainable socio-technical transitions: leading, facilitative, coordinative and persuasive. Analysis on four case based upon this typology shows different transition polices of each transition pathway in analytical aspect. It provides basic criteria for policy makers to design effective transition policies in normative aspect. Also, this paper can contribute to closing the gap between transition research and governance studies.

농가인구의 감소 및 고령화, 고소득 작물 재배, 기후변화 등으로 인해 영농형태가 논농사에서 밭농사로 전환되고 지역별 증감의 차이가 있기는 하나 밭 면적이 증가하는 추세를 보인다. 한편, 밭작물은 논에 비해 기반시설이 부족하고 고소득의 밭작물을 생산하기 위한 시설재배가 늘어나면서 대부분 사계절 확보가 용이하고 수질이 양호한 지하수를 사용하고 있다. 지하수 수요 증가는 지하수위 저하와 지하수 고갈의 우려를 초래하고 있다. 본 연구에서는 농업용 지하수 이용 실태를 분석하고 지하수이용 및 관리 제도 현황을 검토하여 지속가능한 밭용수 공급을 위한 지하수 관리전략을 제안하였다. 진주시를 대상으로 경지유형에 따른 지하수 이용 특성 분석하여 지하수의 수요 특성을 살펴보았는데, 하천 주변 저지대에 큰규모의 밭이나 집단화된 시설재배 지역이 분포하고 있고 지하수 관정도 밀집하고 있었다. 하천에서 떨어진 산간지역에는 지하수 관정이 산발적으로 분포하고 있었다. 지하수 수요는 공간적 위치 외에도 고품질 농업용수에 대한 요구도 원인인 것으로 조사되었다. 밭기반 용수공급 관련 사업과 지하수 자원확보 관련 법제도 등을 고찰하여 밭의 위치, 규모, 용수공급의 수요 특성 등을 고려하여 밭용수 공급을 위한 세 가지 지하수 관리전략을 제안하였다. 우선, 농업용 지하수 이용량 실측 및 정보의 다각화를 통한 정보의 고도화가 필요하다. 둘째, 지하수 이용의 공간적 특성을 고려하여 지표수와 연계한 지하수 이용기반이 구축되어야 한다. 지표수 공급이 가능한 지역은 지표수를 우선 공급하거나 지하수와 혼합 또는 교차하여 공급하고 물공급 취약지역에서는 지하수 공급 기반시설을 구축하는 것이다. 세 번째 전략은 농업용 지하수 시설의 공공관리 강화 및 관리 효율화이다. 특히 지하수이용이 밀집한 지역에서는 지하수 인허가 기준을 강화하고 용도별 관리체계 구축이 필요하다. 밭용수 공급은 농가 소득과 밀접한 연관이 있기 때문에 물이용의 지속가능성과 함께 농가 소득증대를 고려하는 공편인적 관점에서의 관리가 필요할 것으로 생각된다.

The purpose of this study is to develop a content system for the home economics curriculum that integrates Education for Sustainable Development(ESD) and provides basic material for ESD implementation in schools. In view of this, the content elements of the revised home economics curriculum for 2022 were analyzed, and a content system for the home economics curriculum, linked to ESD, was proposed based on the implications drawn from the analysis. The results are as follows. First, the three components of competencies, namely knowledge, values, and skills, were organized equally as a whole. However, the association between the content elements and key competencies in sustainability was found to be insufficient. Consequently, it is proposed that key competencies in sustainability should be cultivated integrally. Second, no content element was identified that can promote social participation. Therefore, it is proposed that solutions should be dealt with at the level of social participation. Third, the connection with Sustainable Development Goals(SDGs) was observed in only six of the 28 content elements. Wherever relevant, it is proposed to incorporate key issues related to SDGs. Fourth, the analysis confirmed that only the environmental dimension of sustainable development was considered. Therefore, it is proposed to pursue coexistence based on temporal and spatial relationship and consider the dimensions of environment, society, and economy in an integrated manner.

Nowaday OECD countries actively introduce the performance audit to evaluate the performance of public policies. Motivated by the current trend in practice, this paper presents performance audit indices and methodology developed for evaluating the transportation investment projects and policies. The main contribution of this study would be twofold:1) key performance indices, 5Es + 4Cs rule, and methodology of performance audit are derived from foreign (GAO, NAO) and domestic (BAI) audit reports; 2) checklists (key issues and focuses) of performance audit are suggested as ranks. It is also suggested that further studies are needed to maintain the indices and the methodology to achieve sustainable performance of transportation projects and policies.

Sustainable development in society has become the center of focus in many fields such as industry, environment, health, culture, etc. Considering that the concept of heritage involves understanding it as a 'resource' to improve the quality of people's lives, sustainability is an important goal that heritage policy has to achieve. Adopting the definition of sustainability in the 1987 Brundtland Report, this paper defines the concept of sustainability with respect to heritage, as well as their respective roles. Following that, three action principles are presented: value-based conservation, rational decision-making, and community involvement. Two cases demonstrating how the three principles should be practiced in managing change are then illustrated. Considering that heritage can play its role as a resource once its significance is protected, this paper argues that value-based rational decision-making is of paramount importance and the first principle. Conservation aims to manage change by practicing a cyclic process of value identification, value sustaining, and value dissemination. Therefore, this paper argues that all processes should be connected in the context of heritage values. A rational decision-making process practicing value-based conservation is then suggested. This paper argues that rational decision-making can only be practiced once values are identified by objective criteria and managed by rational judgment upon impact assessment. Community involvement, the third principle, is necessary to realize value-based conservation and rational decision-making. Recognizing that a community is a beneficiary of heritage and a creator of a beneficial process at the same time, it discusses the role of community and the importance of this role in policies for the sustainability of heritage. This paper concludes with a set of recommendations to improve policies after examining the two decision-making cases.

This study aimed to evaluate the applicability of "food and nutrition standards for child care setting in the Seoul Metropolitan Government" using quantitative and qualitative surveys and lay the groundwork for future expansion. To evaluate the understanding and applicability of each item of the standards and utilize goodness of fit as an evaluation item to improve practicality of the child care center's health foodservice, we surveyed 82 child care centers, kindergartens, and community children centers in Seoul by e-mail through the Seoul Metropolitan Government in November 2015. Using focus group interviews with directors of child care centers and kindergartens as well as dieticians of child care support centers who had conducted public foodservice in Seoul, the appropriateness of each standard was finally reviewed, and amendments to extend this standard were derived. Results of the survey show an understanding of 86.9% and an applicability of 80.7%. Moreover, the applicability of the evaluation items for assessing improvement of health foodservice practices at the child care center was 82.6%. Qualitative evaluation of the applicability of standards through focus group interviews identified four factors for extended application: necessity of a guideline for separate food ingredient suppliers, conformity of the basis and purpose of the item, consideration of contextual situations, and necessity of establishing a Seoul-level foundation. Therefore, guidelines for the standards should be suggested for those providing public food services for children. Furthermore, separate guidelines categorized by items that food ingredient suppliers need to provide should be mandatory or recommended. Evaluation of the applicability of the standards suggests that revising and supplementing the guidelines in order to extend the standards can contribute to health promotion and a sustainable environment for children using public foodservice. Follow-up studies and supports are needed for sustainable food and nutrition management programs.

This study investigated the criteria for evaluating the impact of artificial intelligence services. The study classified AI evaluation targets into two areas: AI service and AI technology, and identified influence, sustainability, efficiency, effectiveness, and appropriateness as potential evaluation criteria. The time aspect of AI service evaluation was divided into pre-evaluation and post-evaluation, with pre-evaluation focused on reviewing items during development and design. The AI service area was classified into public, private, and mixed forms, and the impact assessment was classified as vertical or horizontal. The application of AI services was divided into normative and regulatory aspects, and the purpose of the evaluation could be impact or process evaluation. The subject and field of the AI service could also be used for classification purposes. The results of this study can be used to support the creation of AI service impact policies and countermeasures. However, further research is needed to develop specific indicators based on the criteria identified in this study to evaluate the impact of AI services.

Even though the importance of emotional aspects in design has been discussed and researched actively, researches mainly focusing on the emotional aspects expressed through architectural materials have been rare. Thus, Previous researches were investigated to draw typical categories to express emotional characteristics through architectural materiality. Case study shows Zumthor's practical methodologies in these state: tectonic expression with creative tectonic methods and local residents' voluntary-participation in construction; enhancement of intimate emotional ties with the local heritage through the usage of local materials and traditional construction techniques; coexistence of past and present materials, and showing the change of materiality via weathering; activation of synesthesia by touching multiple senses; sustainability by using environment friendly materials and construction methods. The results can be hopefully helpful to future researches related to emotional aspects on spatial design.

This study measured the environmental efficiency of 21 international airports based on sustainability reports issued by each airport for 2018. As many sectors in the industry paid attention to social and environmental responsibilities, airport operators comprise one of the leading sectors that streamlined their facilities to become increasingly sustainable and environmental. Nevertheless, studies on the environmental operations of airports are insufficient compared with studies on economic or operational efficiency. Therefore, the current study aims to determine any possible improvement in the environmental inefficiency of airports with the utilization of directional distance function (DDF) and to examine operational efficiency with the application of the data envelopment analysis (DEA). The majority of airports have operated their facilities efficiently, but not all have effectively managed pollutants generated by airports. Furthermore, many airports can still potentially reduce CO₂ and water consumption. This study suggests several implementable environmental improvements to the aviation sector. Moreover, other industrial sectors may use the research as a benchmark for enhancing environmental efficiency.
