In this study, the relationship between Baltic Dry Index(BDI) and maritime trade volume in the dry cargo market was verified using the vector autoregressive (VAR) model. Data was analyzed from 1992 to 2018 for iron ore, steam coal, coking coal, grain, and minor bulks of maritime trade volume and BDI. Granger causality analysis showed that the BDI affects the trade volume of coking coal and minor bulks but the trade volume of iron ore, steam coal and grain do not correlate with the BDI freight index. Impulse response analysis showed that the shock of BDI had the greatest impact on coking coal at the two years lag and the impact was negligible at the ten years lag. In addition, the shock of BDI on minor cargoes was strongest at the three years lag, and were negligible at the ten years lag. This study examined the relationship between maritime trade volume and BDI in the dry bulk shipping market in which uncertainty is high. As a result of this study, there is an economic aspect of sustainability that has helped the risk management of shipping companies. In addition, it is significant from an academic point of view that the long-term relationship between the two time series was analyzed through the causality test between variables. However, it is necessary to develop a forecasting model that will help decision makers in maritime markets using more sophisticated methods such as the Bayesian VAR model.

The application contents, process, and its limitations are discussed for the setting of Korean legal guides & criteria for water cycle and ecological condition in development project of land use by thorough comparison and examination of prerequisites and credits of water cycle and soil+vegetation by USA's SITES (Sustainable Sites Initiative). In the case of SITES, due to the implementation procedure operated as a non-governmental independent assessment system by Green Business Certification, Inc, the natural condition of water cycle and soil-vegetation items-the key element of ecosystem services can be quantitatively assessed, well along with its legal and institutional guidelines and regulations. On the other hand, in the case of Korea, as a part of the national certification procedure for green building, the ecological area ratio system still have very limited role as an only amenity resource in the creation of artificial green spaces and insufficiency of management system for rain water. In conclusion, it was understood as an urgent situation in necessary for prompt establishment of site's sustainability certification system at the national level, based on management of water circulation and natural soil & vegetation in developed area with consideration of various land uses and types of development projects.

The purpose of this study is to develop community design evaluation factors for sustainable urban regeneration and to suggest considerations for sustainable community design by analyzing excellent community design cases. Through literature review, previous studies on the concept and core items of sustainable urban regeneration, and the concept and components of community design were considered. In addition, evaluation indicators for sustainable community design were developed in the socio-economic, physical, environmental, historical and cultural dimensions through the analysis of the linkage with the evaluation factors of community design through the analysis of previous studies. The evaluation index consists of 3 evaluation items and 9 items including social performance and participation at the social level, economic feasibility at the economic level, environmental characteristics at the physical and environmental level, accessibility, contextuality, locality at the historical and cultural level, identity, and artistry. Includes dog evaluation factors. Reliability and effectiveness are secured through the developed evaluation index and detailed description and expert verification. Exploratory factor analysis and expert interviews were conducted through the survey, and as a result of the analysis, the stability and Cronbach'α coefficients were verified, and the validity of the community design evaluation index considering sustainable urban regeneration was recognized through expert interview. The results of this study are considered meaningful in that they can provide basic data for the improvement of community design for sustainable urban regeneration in the future.

Keen attention has been directed at "smart tourism cities" due to its role of solving urban problems arising from modern tourism development. However, some local governments are making huge investments in developing uniform tourism apps without specific directions or guidelines for the transformation of smart tourism cities. Accordingly, this study aims to develop a standardized and objective smart tourism competitiveness index and evaluate the competitiveness rankings of various cities around the world. The index comprises the five subindices of attractiveness, accessibility, digitalization readiness, sustainability, and co-partnership. The analysis results have shown that Singapore is the most competitive smart tourism city, followed by Amsterdam, New York City, Seoul and Barcelona, with Ho Chi Minh and Bangkok being relegated to the bottom of competitiveness rankings. We expect that this index can be employed as a global standard for continuously and systematically monitoring smart tourism city-related projects in the future.

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.

Industrial Revolution is a concept and a development that has fundamentally changed our society and economy. Industry 4.0 focuses on the end-to-end digitization of all physical assets and integration into digital ecosystems with value chain partners. At present, we find ourselves at the beginning of this fourth stage, which is characterized by so-called "Cyber-Physical Systems". These systems are a consequence of the far-reaching integration of production, sustainability and customer-satisfaction forming the basis of intelligent network systems and processes. If South Korea ran toward global ICT with the advent of the Fourth Industrial Revolution, North Korea has adhered to a unique Juche science and technology. ICT in South Korea and North Korea seems very difficult to find common interests. However, as seen in the Internet and intranets, information and communication technology can find similarities in many areas than in general science and technology. There are many differences not only in the level of ICT and science and technology but also in the direction. And IT terminology and all technologies are also different. What are we preparing for the unification of North and South Korea? If we look at the science and technology sector at present, there seems to be no systematic preparation by the government. South Korea and North Korea need to be prepared for science and technology cooperation. First, it is necessary to understand the exact situation of North Korea's science and technology. In this study, we will perform research to establish mid and long term plans for revitalization of ICT cooperation between the two Koreas. In this study, we will determine the extent to which the two Koreas utilize ICT based on available ICT capabilities and technologies. To do this, we conducted research to measure and evaluate the ICT development index of North Korea using ICT international index.

This study was conducted to examine the effects of a healthy dietary life and purchase of environmental-friendly food materials according to a mother's lifestyles of health and sustainability (LOHAS) attitudes. The subjects consisted of 295 mothers. The findings are summarized as follows. The mother's LOHAS attitude index averaged 3.39 points out of 5 points. High LOHAS attitude items were "I participate actively in separating the trash collection" (4.16 points), and "I recycle dresses that I do not wear by taking them to the recycling center" (4.08 points). In contrast, LOHAS attitude items for "I do community service activity on the weekend" (2.57 points), and "I try to serve in the local community" (2.63 points) scored very low. A high LOHAS behavior index occurred for mothers who were "resource saving", whereas "social welfare" scored low. Mother's intention to purchase environmental-friendly food materials averaged 3.61 points. Mother's health dietary life attitude score averaged 3.52 points. When age, monthly income, and the environmental-friendly food materials purchase ratio of the mother was high, the health dietary life performance was high. The LOHAS attitude index of mothers had an impact on the purchase intention of environmental-friendly food materials in resource saving and environmental-friendly oriented propensity groups. The LOHAS attitude index of mothers impacted healthy dietary life in environmental-friendly, family and health oriented propensity groups.

Objectives: Transformation through a sustainable food system to provide healthy diets is essential for enhancing both human and planetary health. This study aimed to explain about sustainable diets and illustrate appropriate measurement of adherence to sustainable diets using a pre-existing index. Methods: For literature review, we used PubMed and Google Scholar databases by combining the search terms "development," "validation," "sustainable diet," "sustainable diet index," "planetary healthy diet," "EAT-Lancet diet," and "EAT-Lancet reference diet." For data presentation, we used data from National Health and Nutrition Examination Survey, 2017-2018, among adults aged 20 years and older (n = 3,920). Sustainable Diet Index-US (SDI-US), comprising four sub-indices corresponding to four dimensions of sustainable diets (nutritional quality, environmental impacts, affordability, and sociocultural practices), was calculated using data from 24-hour dietary recall interview, food expenditures, and food choices. A higher SDI-US score indicated greater adherence to sustainable diets (range: 4-20). This study also presented SDI-US scores according to the sociodemographic status. All analyses accounted for a complex survey design. Results: Of 148 papers, 16 were reviewed. Adherence to sustainable diets fell into 3 categories: EAT-Lancet reference diet-based (n = 8), Food and Agriculture Organization (FAO) definition-based (n = 4), and no specific guidelines but including the sustainability concept (n = 4). Importantly, FAO definition emphasizes on equal importance of four dimensions of diet (nutrition and health, economic, social and cultural, and environmental). The mean SDI-US score was 13 out of 20 points, and was higher in older, female, and highly educated adults than in their counterparts. Conclusions: This study highlighted that sustainable diets should be assessed using a multidimensional approach because of their complex nature. Currently, SDI can be a good option for operationalizing multidimensional sustainable diets. It is necessary to develop a Korean version of SDI through additional data collection, including environmental impact of food, food price, food budget, and use of ready-made products.

This study analyzes the effect of alternatives and estimates alternatives evaluation index (AEI) using PCSWMM and weighted summation method. PCSWMM considering combined sewer overflows (CSOs) in the Mokgamcheon watershed was used and effectiveness analysis of alternative was conducted to develop not only flowrate but also the pollutant of BOD and SS. Indicators of AEI are selected using sustainability evaluation concept, driver-pressure-state-impact-response (DPSIR) framework and calculated by weighted summation method. After estimating AEI, alternatives was classified into three groups G (Good), A (Acceptable) and P (Poor) grade. As a results, it is analyzed that alternatives applied to Oryucheon were G grade and those of Yeokgokcheon were P grade and the remainings were 'A' grade. This result will be effective to the integrated watershed management for sustainablility.

This study is to explore implications for sustainable development of Yangdong Village in Gyeongju through identifying effect of its designation as a World Cultural Heritage on residents' quality of life. The following are the findings achieved by empirical analysis. First, eight valuable factors of placeness were identified through factor analysis, about which residents were especially conscious in terms of "living condition", "cultural environment", "economic QOL", "natural environment conservation", "sense of community", "cooperative facilities", "control over increasing population", "transport environment". Second, the importance -satisfaction scores of identified 8 factors were found very high in importance showing relatively low level of low level of satisfaction. Especially, what caused residents's low QOL was economic status-concerned factor showing the lowest QOL index, and other factors such as cooperative facilities and transport environment negatively impacted on resident's QOL as well. Also, it was revealed that residents had a positive attitude toward entering of their village into UNESCO world heritage sites with hope that it would improve their economic QOL. Based on these results, implications for sustainability of Yangdong Village and research limitations were discussed, and further research direction was supposed.
