도시와 농촌간의 균형 있는 발전을 유도하기 위해서 탄생된 도농통합시는 지역특성을 고려하지 않은 무분별한 개발양상으로 인해 지역적 불균형이 더욱 심화되고 있는 실정이다. 따라서, 본 연구는 경상북도의 도농통합시를 대상으로 지속가능한 공간계획을 수립하기 위한 선행연구로서 지역특성 및 유형화 분석을 수행하고자 하였다. 먼저, 지역특성을 규명하기 위해서 인구규모, 농업구조, 생활환경 등이 반영된 변수들을 중심으로 인자분석을 적용한 결과, 개발지향적 인자, 농업적 인자, 생활환경적 인자, 미작적 인자, 과수적 인자가 추출되었고, 지역유형은 과수농업중심형, 중 소규모 농업형, 과소 침체 농촌형, 도시화 진행형, 도시 농촌 혼재형, 동남부해안 공업형으로 군집화되었으며, 지역유형구분의 신뢰도를 통계적으로 검증하기 위해 판별분석을 적용한 결과, 제II, V, VI유형은 100%이고, 나머지 유형은 90%정도의 신뢰도를 가지는 것으로 나타났다.

The purpose of this study is to provide basic materials for working out differentiated marketing strategies appropriate to the visitors and potential visitors of rural tourism for the sustainable development of rural tourism. The study was conducted through a questionnaire survey fur 500 adults aged 18-year-old or older residing in downtown Seoul, and the characteristics of the visitors and potential visitors of the rural tour were analyzed through frequency analysis and logistic analysis. The analysis results are summarized as follow. In many cases, they obtained information on the rural tourism chiefly through mass media and decided their participation after listening to the stories of nearby people or visitors. The survey showed that the estimated necessary expenses of the potential visitors were more than actual ones of the visitors. It was analyzed that the reception attitude of residents was a factor to have the most significant effect on the participation of rural tourism, while necessary budget for potential visitors.

This paper explored the digital application of intangible cultural heritage from the perspective of cultural ecology. Through field investigations, combined with cultural ecology theory, an ontology-based semantic web technology was proposed, and Nanjing "Yunjin" brocade weaving technique was selected as the research object. The specific steps were as follows: First, based on the field surveys and cultural ecology theory, the intangible cultural ecological environment was divided into natural and social environments. Next, constructing the intangible cultural heritage ontology was constructed, including the collection and collation of Nanjing Yunjin weaving technique knowledge corpus, based on user needs analysis and corpus analysis, CIDOC CRM was used to create rules to build the ontology. Finally, based on the MediaWiki platform and Semantic MediaWiki, the semantic web model of the intangible cultural heritage was designed, and its semantic retrieval function was realized, thereby achieving the practical application of intangible cultural heritage digitization. Based on the perspective of cultural ecology, a set of intangible digital application models was proposed, which expanded the digital application of the cultural ecology theory, verified the application of this model in the sustainable development of cultural tourism, and provided reference for the sustainable development of cultural tourism.

The UN's 17 Sustainable Development Goals (2018) were created to address environmental pollution and climate change (SDGs). The goal of this study is to find out how well-informed Vietnamese students are about the SDGs. Knowledge, attitudes, and practice (KAP) questionnaires were used to survey 1,010 students across Vietnam's universities, and the data was analyzed using SPSS software version 20. The findings suggest that both knowledge and attitude have a positive impact on the practice level. However, when comparing the correlation between the variables and the level of practice, advantage belongs to the relationship between the attitude and the level of practice (r = 0.982^**, n = 1010, p = 0.00), the correlation between knowledge and practice level is weaker (r = 0.616^**, n = 1010, p = 0.00). Statistical data also show that many Vietnamese students do not have access to information about the SDGs. The majority of the target population who have been contacted and have a basic understanding of the SDGs have done so through their academic degree. From there, it is clear that education is the most effective strategy for Vietnamese students to modify their environmental understanding and actions.

This paper intends to raise some of urban policy issues of managing and planning Seoul for the twenty first century. As one of the world's most dynamic megacities, Seoul is faced with at least two trends: one is globalization of the economy, and the other is humanization of urban development in relation to people's quality of life. Given this context, there are emerging issues in a time of transition as the following; pedestrianization, decline of city master plan, micro land use control, citizen involvement, metro-wide management, infrastructure provisions and maintenance, sustainable development, urban information sustaniable development, urban information system, and public-private partnership.

Developments in power electronics have enabled the widespread application of Pulse Width Modulation (PWM) inverters, notably for connecting renewable systems to the grid. This study demonstrates that a high-quality power can be achieved using a stand-alone inverter, whereby the comparison between the power quality of the stand-alone inverter with battery storage (off-grid) and the power quality of the utility network is presented. Multi-loop control techniques for a single phase stand-alone inverter are used. A capacitor current control is used to give active damping and enhance the transient and steady state inverter performance. A capacitor current control is cheaper than the inductor current control, where a small current sensing resistor is used. The output voltage control is used to improve the system performance and also control the output voltage. The inner control loop uses a proportional gain current controller and the outer loop is implemented using internal model control proportional-integral-derivative to ensure stability. The optimal controls are achieved by using the Sisotool tool in MATLAB/Simulink. The outcome of the control scheme of the numerical model of the stand-alone inverter has a smooth and good dynamic performance, but also a strong robustness to load variations. The numerical model of the stand-alone inverter and its power quality are presented, and the power quality is shown to meet the IEEE 519-2014. Furthermore, the power quality of the off-grid system is measured experimentally and compared with the grid power, showing power quality of off-grid system to be better than that of the utility network.

In South Korea, the conflict between development and conservation policy still exist among government ministries, and conventional development plan often has priority over conservation policy. Establishment of sustainable development and comprehensive management policy employing the results of ecosystem service studies are highly warranted, but researchers in South Korea are still limited and often misuse the concept of ecosystem services. Thus, we aimed to introduce the concept of Ecosystem Service (ES) and related terminologies such as Social-Ecological Systems (SESs), ecosystem function, trade-off, and human well-being in this paper. Additionally, this article reviewed and arranged key approaches in ES studies as follows: 1) field works, 2) mapping ecosystem services, 3) valuing ES, 4) quantifying trade-offs between ES and 5) understanding SESs. Based on those results, we suggest that field works for basic information have the first priority to be conducted among ES studies. Once basic information is sufficiently accumulated, researchers can perform applied ES research with accuracy. Finally, results of ES studies conducted by five approaches allow decision makers to consider both natural system and society simultaneously, and hence the results can be utilized for sustainable development and conservation policy based on ecosystem-based management.

본 연구의 목적은 가짜뉴스의 개념과 정의를 오정보/허위정보를 중심으로 살펴보고 현대사회가 가짜뉴스와 같은 정보왜곡으로 인한 사회 현실 왜곡, 민주주의 훼손에 대해 대응할 방안을 살펴보고자 하는 것이다. 이를 위해 가짜뉴스의 개념을 사실성과 속이고자 하는 의도성에 바탕해 살펴보고, 가짜뉴스의 생성과 파급이 이루어지는 우리의 사회 환경을 데이터화 관점에서 살펴보았다. 이러한 환경에서 인류의 정보접근과 활용에 중추적 역할을 하는 도서관계는 UN 2030 의제인 지속가능한 발전목표의 실현을 위해 보편적 리터러시 교육의 구축과 제공을 위해 힘써야 할 것이라 주장하였다. 데이터화 정도와 사회의 정치·경제·사회·문화적 배경에 따라 데이터 커뮤니케이션 유형을 조사 분석하여 해당 사회를 이해하는 것이 보편적 리터러시 교육항목 구성에 핵심이며 이런 이유로 보편적 리터러시는 각각의 사회가 가지는 데이터화 정도와 이용자에 따라 유연성있게 구현되어야 한다고 결론지었다.
