This study shows the first output of the three-year project (2021-2023) to develop a Smart Water City (SWC) Global Standard and Certification Scheme ley by K-water, International Water Resources Association (IWRA) and Asia Water Council (AWC). There are three major parts in the first year. In Part 1, it investigates the essential features of cities today and details the water challenges currently faced and likely to be confronted in the future. It also investigates the functions that water fulfills in the urban environment, and how ICTs can contribute to improving those functions by each Urban Water Cycle. A definition of a Smart Water City is proposed following a discussion on the meaning of "smart development". This part of the report also presents different city cases from countries around the world to illustrate the urban water challenges and the technological and non-technological solutions that cities have put in place, including national and/or local policies and strategies. In Part 2, it defines what global standards indicators and certification schemes are and identifies their characteristics. Especially, it analyses in detail eight relevant standards and certification schemes measuring sustainable development and/or water resources management in urban settings. Standards elaborated by international organizations are distinguished from those developed by the private sector, non-governmental organizations, and by academia. Finally, this study suggests the right direction to develop SWC global standard frameworks and certification schemes. And then, it shows the main tasks for the Stage 2 (second year) project. Basically, the framework for a future SWC standard (consisting three main pillars: Technical, Governance and Prospective pillars) will be fully defined in Stage 2.

본 논문에서는 ISO 8879(Standard Generalized Markup Language)에 근거하여 문서의 논리 구조를 정의하고 있는 DTD(문서형 정의부 : Document Type Definition)를 자동 편집하기 위한 시스템을 설계 및 구현하였다. SGML DTD는 문서의 논리 구조 유형을 정의하는데 그 구조가 복잡하여 일반 텍스트 편집기로 작성하기가 쉽지않다. 그러므로 일반 사용자도 쉽게 사용할 수 있도록 그래픽적으로 윈도우 환경하에서 트리 형태로 표현하여 직접 조작함으로써 복잡한 DTD를 쉽게 작성할 수 있는 DTD 자동 생성 및 편집하는 시스템에 대해 연구하였다. 이를 위해 SGML을 중심으로한 문서 구조를 분석하고, SGML 문서처리 모델을 연구하였으며, SGML DTD를 구성하는 엘리먼트(element), 앤티티(entity), 속성(attribute), 표기법(notation), 주석(comment) 등의 논리 구조를 윈도우상에 트리 형태로 표현하였다.

문서기술언어 SGML(Standard Generalized Markup Language, 표준 범용 마크업 언어)과 그 전문 데이터베이스(도표나 화상 포함)에의 적용에 대하여 해설하였다. SGML을 적용한 전문데이터베이스의 구조는 SGML로 작성한 DTD (document type definition)로 표현하고 텍스트자체는 DTD에 따른 범용 마크업을 사용하여 기술한다. 본고에서는 장, 절, 단락 등의 계층구조와 각주, 도표, 화살 등의 비계층 구조로 되어 있는 문서 구조를 어떻게 표현하는가에 대하여 예를 들어 해설하였다. 그러고 SGML의 효과, 전자 출판, 검색 시스템, 하이퍼텍스트, SGML 관련 도구 등에 대해서도 해설하였다.

본 연구의 목적은 자연수 나눗셈의 정의를 확장하여 분수 나눗셈에 적용함으로써 초등학교 수학에서 분수 나눗셈의 알고리즘을 정당화하는데 있다. 먼저 초등학교 수학에서 분수 나눗셈을 도입할 때 고려해야 할 준거들을 도출하여 제시하였다. 이를 바탕으로 분수 나눗셈의 표준 알고리즘을 유도하는 기존의 방식들이 분수 나눗셈 도입 과정에 적절한지를 고찰하였다. 또한 분수 나눗셈을 정의하였으며, 단위원 분할 모델과 정사각형 분할 모델을 통하여 구체적 조작 활동을 함으로써 등분제와 포함제 상황의 분수 나눗셈에서 표준 알고리즘을 자연스럽게 정당화하였다.

Korea's national R&D projects are increasing year by year. However, it is necessary to improve the quality of R&D result. In this paper, we introduce the developing and adjusting the R&D standard process based on process approach in ETRI. It is expected that the definition of R&D standard process will contribute to improve customer satisfaction and quality of R&D result through standardization and continuous improvement activities.

IEEE 802.16 Wireless MAN standard specifies the air interface of fixed point-to-multipoint broadband wireless access systems providing multiple services. Among the service classes supported by the wireless MAN, the best effort service class is ranked on the lowest position in priority and is assisted by a MAC scheme based on reservation ALOHL Such MAC scheme must include a number of components, while many of them are not specified in the standard. In this paper, we thus reveal main components of a MAC scheme supporting the best effort service and present candidate schemes implementing such components. Combining schemes for implementing components, we then construct distinctive MAC schemes supporting best effort service. In designing a MAC scheme, the delay performance induced by the scheme should be considered since scarce resource may be available for the best effort service after the preemptive resource occupation by other service classes. In this paper, we focus on the delay fairness among the subscriber stations using the best effort service. For evaluating a MAC scheme in delay fairness, we present two definitions of delay fairness and provide a criterion for optimal MAC scheme according to each definition of delay fairness. Using a simulation method we investigate the mean delay performance exhibited by each MAC scheme arid find an optimal scheme in delay fairness. From numerical examples, we observe that SR/ED/PG＋P scheme has strong delay fairness compared with MR/ED/PG＋P and SR/ED/PG＋D schemes according to a definition of delay fairness. However, other schemes are rather shown to have better delay fairness when the other definition is adopted.

The purpose of this study is to grasp the effectiveness of evacuation safety design by verifying the appropriateness of the standard of occupant load factor for residential buildings. To this end, the definition and current standard of occupant load factor for residential buildings were analyzed, and the problems of the current standard were clarified by interviewing professionals. In addition, changes in occupant load factor were examined by year based on statistical research, and evaluation on the current standard $18.6m^2/pers.$ was performed. As for evaluation methods, the need of redesigning of evacuation capacity was investigated by using evacuation simulation. As a result of the analysis, the most serious problem was clarification of the applicable standard for residential officetel, where the average occupant load factor was $26.1m^2/pers.$, which was not appropriate. However, as a result of evaluation on evacuation capacity, although there was no difference between statistical research results and the current standard in terms of evacuation capacity, when the standard for business facilities was applied to officetel, evacuation time doubled. Thus, this study suggests that when the current standard is applied to residential officetel, it is necessary to separate between residential use and business use.
