The cybermoney marketplace has been improved by many changes of a business model, such as the development of online exchange, online mileage, potalmoney and gamemoney and so on. Because of its continuous growth, the need for categorizing manketplaces and researching on cybermoney marketplace status and problems has been increased. Therefore, in this paper, We researched about cybermoney marketplace's status and problems. We suggest the indicator that could classily cybermoney. We examined the status of cybermoney marketplace and identified the issues of development of cybermoney.

경제가 발전함에 따라 산업화 및 도시화로 인해 많은 지역에서 지속 가능한 수자원관리의 어려움을 겪고 있으며, 기후 및 환경 변화는 지표수의 증발을 증가시키고 강우 및 기타 수문학적 순환과정의 시기와 역학을 변화시킴으로써 물에 대한 스트레스를 높이는 등 다양한 문제가 발생하고 있다. 이러한 환경 변화로 인해 개인, 국가 등 전 세계가 여러 형태의 현실적 물 문제에 당면하고 있음에 따라 본 연구에서는 위와 같은 물 관련 문제를 평가할 수 있는 물 안보 평가 방법을 제시함으로써 국가차원의 수자원관리에서 발생하는 문제점에 대한 해결 방안을 모색하고자 하였다. 본 연구에서는 물 안보를 적절한 제도, 바람직한 거버넌스 등 물과 기타 요소 간의 연계성을 바탕으로 깨끗한 물과 적절한 위생 서비스를 사회구성원 모두에게 공평하게 제공하고, 인간 생명과 환경을 오염 및 물 관련 재해로부터 보호하며, 수생태계 보전과 회복을 달성하는 능력 등 4가지 분야로 정의하였다. 이러한 물 안보 상황을 평가하기 위해 1) 사회적 공평성(social equity), 2) 경제적 효율성(economic efficiency), 3) 환경 지속성(environmental sustainability), 4) 수재해 회복 탄력성(resilience to water-related disasters)과 같이 네 가지 핵심 분야로 구분하였으며, 4개 핵심분야의 특징을 반영한 14개 하위 지표를 선정하였다. 국가별 평가는 아시아 국가를 대상으로 진행하였으며, 본 연구가 제시한 물 안보의 정의와 평가 프레임워크를 기반으로 수자원 현황 및 문제점 등을 평가하고 향후 국가별 물 관리 정책의 방향성을 제시할 수 있을 것으로 기대된다.

This paper was intended to evaluate environmental policies of South Korea and compare its environmental sustainability with other Eastern Asian countries in terms of some sustainability measures. To meet the purpose, the paper is composed of three parts: a brief and critical review of Korea's current environmental policies, comparison of its sustainability with other Eastern Asian countries in terms of well-known environmental sustainability indices, and comparison in terms of a less well-known alternative measure. Korea's environmental policies as stipulated in "Green Vision 21", "Green Korea 2005" were evaluated in light of OECD EPRK 2006. Korea's environmental performance is then compared with other countries based on such environmental sustainability indices as EF, ESI, EPI and EVI. Unfortunately the well-publicized indices to measure sustainable development (SD) seem to fail in measunng SD and in providing comparability, because it does not base on the genuine concept of SD. Therefore, we tried to suggest an alternative measurement in terms of sustainability quantity (SQ), which is presented for South Korea and her major trading partners, such as USA, Japan and China.

This study aims to provide lesson plans that can simultaneously achieve both the learning goals of the 'Human Development & Family' domain of the 2015 revised Technology & Home Economics curriculum and the Sustainable Development Goals. Four steps including analysis, design, development, and evaluation and revision were followed. In the analysis step, the 'Changing Families and Healthy Families' unit was selected as it is relevant to the nine subgoals of the SDGs. In the design step, three sessions were planned with a problem-solving project approach. In the development step, three lesson plans for each session, individual and group activity worksheets for students, and guidelines for teachers were constructed. In the evaluation and revision step, criteria for evaluating the lesson plans were developed reflecting both the goals of the Home Economic curriculum and the SDGs. The validity of the lesson plans was reviewed by a panel of experts. Then, the revised lesson plans were finalized. This study provides an illustrative example of the lesson plans in the secondary education context that can be used to achieve the learning goals of the Home Economic curriculum and the Sustainable Development Goals at the same time.

This study focuses on the phenomenon that K-POP has become spotlight as killer contents which can be spread over the world beyond Asia. In order to identify critical factors of successful impact of K-POP on other cultures, the influence of the change in media on the globalization of popular culture was explored and the related requirements were analyzed. Furthermore, the potential markers for K-POP, a core field of the Korean Wave, were also analyzed and specific factors such as effective infrastructure of among producer of contents, platform subscriber, network provider, terminal enterprise and retailers for building new businesses model were investigated in detail.

The purpose of this study was to investigate the status, issues and improvement of Korean Childcare Accreditation and to suggest some developmental directions of Korean Childcare Accreditation. For this purpose, we examined Korean and accreditation systems abroad and the previous research related to the accreditation. Finally, we presented some problems about Korean Childcare Accreditation and alternative ways to solve them. In other words, to achieve a true purpose of accreditation, we have to convert a philosophical paradigm and childcare staffs have to be the subject of accreditation. In addition, we need to hold various viewpoints, indicators, and evaluation methods to recognize discrimination and multiplicity of individual childcare centers. And we have to hold cooperative relationships among childcare centers, parents, community, and government.

Informative contents Industry shows stable capital structure, excellent profit index high growth rate and high productivity on the average in step with the evolution of digital technology, but it shows the aggravating trend gradually in almost all the indexes. It is because the enlargement of supply market proceeds so faster than the increase of market demand that the competition is intensified and relatively easy to advance into the market according to the development of informative contents industry. The exploitation of new market and the reclamation of new technology are needed to contrive the continuous prosperity of informative contents industry, and to achieve this, it is needed to support from politic financing and taxation politic aspect.

This paper aims to analyze efficiency of sustainable development of foreign trade in eastern China to reduce the input while maintaining the current output level. This paper adopts relevant input-output indicators of 11 provinces in eastern China from 2016 to 2020 and uses DEA to measure comprehensive efficiency, pure technical efficiency, and scale efficiency from the input perspective. Malmquist index was used to calculate MPI. As a result, from 2016 to 2020, the MPI of all provinces in eastern China was 1.035, higher than 1, and the net technology efficiency was 0.911, lower than 1. Overall, the average technological progress index increased 4.5% to 1.045. It can be seen that the sustainable development efficiency of foreign trade has an overall influence on comprehensive efficiency, net technology efficiency, and scale efficiency. The efficiency of sustainable development of foreign trade in eastern China is mainly limited by its scale. The improvement of MPI in the eastern Region mainly benefits from technological progress. For provinces affected by internal factors, it is suggested to strengthen internal coordination. For provinces affected by external factors, it is suggested to respond appropriately to external factors.

본 연구는 경기도 용인시에 위치한 공공하수처리장을 대상으로 소수력발전 성능특성을 예측하고 경제성을 분석하여 소수력발전소의 건설타당성을 제시하였다. 방류구에서의 수준측량 조사에 따르면 실제 유효 낙차는 4.3m로 나타났다. 최근 5년간 방류량 자료를 살펴보면 일평균 실제 처리량은 약 $30,000m^3/day$로 나타났으며, 우수 유입과 물 사용량이 증가하는 여름 및 가을에 처리량이 증가하였다. 설계유량은 유량변화에 따른 누적 확률밀도와 유량지속곡선에 근거해 산정하였으며, 시간빈도로 보았을 때 17%의 유량이 지속되는 $0.35m^3/sec$가 설계유량으로 나타났다. 예상되는 수차 발전용량은 11kW급이며, 시스템 가동율은 74%, 그리고 계통선에 송출될 수 있는 연 전력생산량은 71.3MWh로 나타났다. 경제성 평가는 신재생에너지 경제성 분석 도구인 RETScreen 프로그램을 사용하여 B/C ratio, IRR, 개발투자비 등의 경제성 평가지표들을 산정하였다. 편익(Benefit) 산정시 전력기준단가는 133.67원/kWh, 할인율 7%를 적용하였으며, 비용(Cost) 산정시 유지관리비는 초기 건설비의 1%, 사용연한 30년을 적용하였다. 경제성 분석결과 기흥레스피아의 소수력발전소 건설시 초기 건설공사비가 $165,000 일 때, B/C 1.0, NPV $3,534, 투자회수기간 15.1년으로 산정되었고 따라서 초기 건설비용이 $165,000 이하일 때 가장 경제적인 것으로 파악되었다.

To improve M&S and SBA, it is important that their capability and maturity models should be developed. In general, capability and maturity models provide the standards for growth and improvement as well as the assessment on the organizational maturity level and the process capabilities, which are composed of a standard reference model and appraisal methods. In this paper, following introduction of a standard reference model for SBA in brief, we investigate some appraisal methods by survey and provide frameworks of appraisal method for SBA.
