Green Standard for Energy and Environmental Design (G-SEED) is evaluates the eco-friendliness of the building as an abjective means. Study in green building is made actively, and is being developed through constant revision. However, study results of green building have not been fully reflected in the standard. Therefore, this study analyzes the previous studies about G-SEED and checks the reflection of requirements. This study will be a reference of future revision of G-SEED. Score of items are divided into low and high score items. These items should be reflected appropriately in the standard through the score adjustment. Some requirements proposed in previous studies was reflected, while substantial requirements was not reflected. Proposed improvement requirements are classed as to establish specific standards, strengthen standards, propose a new evaluation method to existing items, and add new items.

One of the problems with the base station equipment is that there is a large difference between the replacement time of the hardware equipment such as the base station equipment and the radio access equipment, and the evolution period of the communication standard. Therefore, the base station communication platform must be flexible enough to handle the evolving communication standards after purchase. Recent research on reconfigurable communications platforms has focused on the efficient architecture of the communications platform to meet these requirements through software downloads while still using existing hardware. This paper presents a prototype of a base station communications platform based on the ETSI standard reconfigurable architecture. The communication platform presented in this paper is implemented as an ETSI standard reconfigurable architecture using a general-purpose DSP (Digital Signal Processor). In the implemented prototype, we verify the real-time feasibility of communication protocol updates through software reconfiguration.

When it comes to design and acquire underwater vehicles such as a submarine and a torpedo according to the process of SBA(Simulation Based Acquisition)/SBD(Simulation Based Design), it is necessary to predict the performance of interest precisely and to perform the test over and over again using the M&S(Modeling and Simulation) of the engineering and the engagement level. In this paper, we research the DEVS(Discrete Event System Specification) and DTSS(Discrete Time System Specification) formalism based standard model architecture for the underwater vehicle which can support both the heterogeneous level of the M&S(Engineering/Engagement) and the different system of the M&S(Discrete Event System and Discrete Time System). To validate this standard modeling architecture, we apply it to the submarine normal diving simulation.

Sustainable building is getting more and more important topic in 21C. Following this trend, building energy saving standard has been reinforced in Korea. Especially, insulation standards are revised continuously after1979. This study aims to evaluate the correlation between the revised insulation standards and heating and cooling loads of a residential building. This study shows that the standard of insulation is more related with heating load than cooling load, and cooling load is more related with other sources such as glass types and solar incidence through windows. In case of highly-insulated building such Passive Houses or Zero Energy Houses, the cooling load should also be considered as important as heating load when revising the building energy saving regulations in the future.

Purpose: The manoeuvring space at doors must be secured for users of walking aids, wheelchair users, stroller users, luggage carriers, etc., so clear criteria must be established. The korean standards for the manoeuvring space at doors need to be improved to present clear criteria depending on the type of entrance and the direction of opening and closing. Method: Korean standard, International Standard(ISO 21542, 2011), German Standard(DIN 18040-1, 2010), Austrian Standard(OENORM B 1600, 2017) and Swiss Standard(Norm SIA 500, 2009) were investigated and analyzed. A comprehensive improvement of the criteria for the manoeuvring space at doors is proposed. Results: The manoeuvring space at doors, which is essential for the disabled to use the door, shall be installed with a comprehensive consideration of the width of doors, the Circulation space, the direction of access, and the method of opening and closing of the door. Korean standards, such as the width of doors, the Circulation space, and the manoeuvring space at doors, are different from international and international standards, which require improvement of standards. The criteria for the manoeuvring space at doors shall be clearly improved so as not to be misinterpreted during the installation of doors and the BF-certification. Implication: The criteria for the installation of doors shall be presented as a comprehensive alternative through continued study of details. In addition, improvements in standards that reflect changes in international standards should be made.

본 논문은 분산 시스템에서의 표준합성환경 기반 수중 교전 시뮬레이션을 위한 방법론이다. 수중 교전 시뮬레이션의 경우 염분과 수온 등의 수중 환경 데이터를 시뮬레이션에 반영하는 것이 중요하다. 분산 시뮬레이션 시스템에서 이러한 환경 데이터의 재사용성과 상호운용성 향상을 위해 합성 환경 표현 및 교환 표준(Synthetic Environmental Data Representation and Interchange Specification, SEDRIS(ISO standard for environmental data))이 개발되었고, 본 논문에서는 SEDRIS를 활용하여 수중 합성환경을 구축한다. 본 논문을 통해 SEDRIS가 합성환경 데이터의 국제 표준이지만 그 방대함과 복잡함으로 인하여 사용이 저해된 문제점을 대기/해양 환경에 대해 효율적인 SEDRIS 기술 활용 방법을 제시하여 해결한다. 본 논문의 최종 목적은 대기/해양 환경 표현을 위한 다차원 격자 기반의 SEDRIS 구조를 구축하고, High Level Architecture (HLA)/Run-Time Infrastructure (RTI) 기반의 분산 시스템에서 대기/해양 합성전장환경 구축에 SEDRIS 적용 방법을 제시한다.
