  • 본 연구에서는 부유식방파제의 입사면과 전달면이 Slit으로 구성되어있어 유수실이 존재하는 투수성 부유식방파제에 대하여 2차원 자유도운동에 따른 발전가능성을 검토하였다. 입사파랑이 부유식방파제 유수실구간의 내부로 유입될 때 발생하는 강한 와류는 입사파랑의 주기와 파고가 증가할수록 궤적이 높고 길게 발생하게 된다. 이러한 원리를 이용하여 부유식방파제 유수실구간 입사면과 전달면에 각각 양방향으로 회전이 가능한 수차를 설치하고 와류 발생에 따른 2차 에너지 생성 가능성을 검토하였다. 실험결과, 입사파랑의 내습에 따라 수차는 시계방향과 반시계방향으로 회전하는 것을 확인할 수 있었으며, 상대적으로 주기가 긴 규칙파랑 실험조건(파고 0.1m, 주기 2.0sec)에서 약 0.5W 내외의 지속적인 전기에너지를 확보하는 것으로 검토되었다.

  • Recently, measures for successful settlement and sustainability of social enterprises have become an important topic. Accordingly, researches related to social enterprises are increasing, but studies measuring sustainability are still insufficient. In this study, in order to seek the sustainability and development of social enterprises in the field of literature and arts, a theoretical model for the sustainability of social enterprises in the field of culture and arts was presented. To this end, interviews were conducted with social enterprises in the field of culture and arts, and the results were analyzed to derive the concept and categorization of sustainability of social enterprises in the field of culture and arts. In addition, the integration between the derived categories is illustrated. For a social enterprise in the field of culture and arts to be sustainable, differentiated culture and arts services are important, and each company must constantly strive for its mission and vision, and a differentiated branding strategy unique to companies is required. This research is expected to lay the foundation for empirical research on social enterprises in the culture and arts sector as data for entrepreneurs and prospective entrepreneurs who run social enterprises in the field of culture and arts.

  • Characteristics of off-grid hybrid renewable energy sources for high mountain villages are discussed. Considering reliability of electric power generation, Photovoltaic (PV)-wind hybrid and PV-hydro hybrid system are suggested. Connecting two or more villages with these hybrid systems, an extended hybrid off-grid can be formed. Sustainability of entire system is important in design of off-grid system, and income generation of the village people using the electricity should be considered.

  • The purpose of this study is to examine the extent of Sustainable Development Goals (SDGs)-related research in the field of entrepreneurship globally since the adoption of the SDGs at the UN General Assembly, and to compare international and domestic research trends in order to determine the direction of SDGs-related research in entrepreneurship in Korea. Utilizing three databases-Web of Science (WoS), KCI, and DBpia- SDGs-related studies in entrepreneurship were extracted by employing specific search terms. After data purification, a total of 356 studies abroad and 4 studies in Korea were used for analysis. After data purification, a total of 356 international studies and 4 Korean studies were analyzed. Due to the limited number of domestic studies, the research trends were examined by conducting frequency analysis and keyword network analysis on international studies alone. Frequency analysis revealed that SDGs research in entrepreneurship primarily focused on sustainability-related terms and was conducted in conjunction with business models, innovation, entrepreneurship education, and strategies. Furthermore, yearly frequency analysis demonstrated an expansion of topics to encompass research on entrepreneurship and SDGs policies, the roles and capabilities of female entrepreneurs in SDGs implementation, energy start-ups and SDGs, directions for implementing SDGs in business schools and SDGs education, indicators for SDGs implementation and evaluation, and technologies for sustainability. The keyword network analysis identified central topics such as business, sustainability, SDGs, innovation, entrepreneurship, business models, and education, with research areas extending to entrepreneurship ecosystems, change and strategy, ethics, and climate. This study holds significance in establishing a foundation for SDGs research in entrepreneurship, which is currently an underexplored area in Korea, by presenting emerging research trends related to SDGs in entrepreneurship.

  • 정보화 사회에서 새로운 교육 서비스의 형태로 활성화되고 있으며, 무한한 변화의 가능성을 내포하고 있는 분야를 선택한다면 홈페이지를 들 수 있다. 이미 홈페이지의 활용은 개인 기업 혹은 모든 조직을 막론하고 다양한 분야에서 사용하고 있으며, 그 증가 추세 또한 급격하다. 교육현장에서는 학부모의 학교 참여와 학생의 교수-학습의 도구, 그리고 학교의 홍보 기능을 담당하는 주요 도구로서 학교 홈페이지의 역할이 점점 부각되고 있으며, 학교 홈페이지는 단순한 홈페이지의 기능뿐만 아니라 학생과 교사의 학습 활동의 주요무대가 되며, 학부모와 교사, 지역사회와 학교의 연결고리로서 그 역할이 확대되어 가고 있다. 홈페이지의 생명은 지속적인 활용과 새로운 내용의 개발 보급이다. 지속적인 홈페이지 내용의 개발과 새로운 활용 형태를 보급하기 위해서는 이미 구축되어져 있는 홈페이지를 평가해 보고 내용 중 어느 부분을 지속적으로 발전을 시킬 것인지를 알아보고 또한 어떤 내용들이 교육적으로 효과가 있는지 대해 조사 분석하여 학교 홈페이지의 활용도와 발전성을 높여야 한다.

  • 자연은 인간이 만들어낸 기술적 해결책들보다 현저히 적은 양의 에너지를 소비하며, 적은 물질로 다양한 구조를 창출해 내는 고효율 최적화 시스템이며, 스스로 정화작용과 선순환을 유지하는 환경 친화적 시스템이다. 이러한 자연에서 영감을 얻어 활용하고 응용하는 기술은 최근 나노-바이오기술의 급속한 발전과 더불어 새롭게 각광받는 융합기술 분야로 부각되고 있다. 나노스케일의 생체물질을 관찰하고 특성을 평가할 수 있는 고성능의 장비가 개발되고, 생체 물질을 분자 단위로 조합하고 합성하는 등의 첨단기술이 발전됨에 따라 자연모사기술도 새로운 전기를 마련하고 있다. 자연 생명체/생태계가 지닌 혁신적인 해결 가능성(Innovation Potentials)을 구현하기 위해서는 자연모사기술 분야에 좀 더 체계적이고 지속적인 관심과 지원을 기울여야 할 것이며, 이를 바탕으로 인류가 당면한 에너지 자원 기후변화 환경 문제 등의 글로벌 이슈를 극복하고 선순환의 개념의 자연모사 에코 기술과 지속가능한 혁신 기술 달성이 가능할 것으로 기대된다.

  • Clean Development Mechanism(CDM) projects under the Kyoto Protocol have two objectives. One is to assist the Parties included in Annex I in achieving compliance with their quantified emission limitation and reduction commitments in cost-effective ways by allowing them to implement emission reduction projects in Non-Annex I countries and receive CERs, which will offset their reduction commitments. The other is to assist Parties not included in Annex I in achieving sustainable development and technology transfers through investments by Annex I countries. However, in reality, it is said that the former objective is achievable but the latter is not. In this light, this article suggests sustainability appraisal criteria applicable for Korea. Among various methodologies, we used the 'multi-attributes utility theory(MAUT)'; one of the 'multi-criteria analysis (MCA)' methodologies judged to be the most practical and relevant. Based on the guidelines of the MAUT methodology, we identified sustainability criteria that meet the guidelines. We took two tracks, the first to find the preferences of Korean experts, and the other to check foreign cases. In all, 37 preliminary criteria were suggested to Korean experts and each criterion was scored, from between 1 and 3, in terms of relevance, possibility of real improvement, easiness of data collection, and preferences. We combined foreign cases and the results of a survey conducted in Korea and selected 12 core criteria and 10 additional criteria. After that, all the criteria were converted into indicators. The indicators were applied to a CDM project for case study. We chose the "Sihwa Tidal Power Project", which is currently the biggest tidal power plant in the world. Twelve core indicators and 3 additional indicators were applied. In order to weight each indicator, the 'analytical hierarchy process (AHP)' was used. A total of 30 experts were asked to suggest weights and 21 answered. Among them, only 14 respondents were proven to meet the consistency ratio. We analyzed the 14 responses through Expert Choice and the CDM project was scored (+)53.082. In addition, sensitivity analysis was undertaken with the result of (+)44.667 to (+)65.522. As a result of this study, it was proven that this project would contribute to the sustainable development of Korea.

  • 유채유를 이용한 바이오디젤의 실질적인 가치는 배럴당 355,000원으로, 현재의 가격은 평가절하되어 있으며 에머지 생산비율(EYR)은 1.27으로서 석유의 8.4에 비하여 효율이 낮아 대체에너지로서의 경쟁력은 없으나 1보다 높아 에너지 소비 절감의 효과는 있다. 환경부하비율(ELR)은 2.46으로 수력발전의 3.3과 Bioethanol의 7.7보다 낮아 환경에 미치는 영향은 작은 것으로 나타났다. 에머지 지속가능성지수(ESI)는 0.52로 재생불가능한 에너지와 외부에서 구입한 재화와 용역에 대한 의존도가 높으므로 지속성이 낮은 것으로 나타났다.

  • 아세안은 군사/안보적 사안에서는 일체감을 형성하였다. 그러나 아세안 방위협력의 고차원적 요소는 아세안 국가간의 공중, 해상, 지상에서의 쌍무적인 군사연습이다. 앞으로 아세안은 지속적인 발전과 함께 쌍무적 협조관계가 강화되며, 궁극적으로 3자간 또는 4자간 협력의 성격을 띠게 될 가능성이 높다. 그러나 이는 시간을 요하며, 실무자들과 정책입안자들사이의 의견일치를 요구하는 것이다. 아세안 역외의 협력은 특히 다른 주요국가들과의 협력으로 확대될 가능성이 있다
