High-rise as a building typology is gaining popularity in Asian mega-cities, due to its advantages in increasing volumetric density with limited land resources. Numerous factors contribute to the formation of high-rise urban form, from economical and institutional, environmental to socio-political. Environmental concerns over the impact of rapid urbanization in developing economies demand new thought on the link between urban environment and urban form. Outdoor and indoor climate, pedestrian comfort, and building energy consumption are all related to and impacted by urban form and building morphology. There are many studies and practices on designing individual "green" high-rise buildings, but far fewer studies on designing high-rise building clusters from the perspective of environmental performance optimization.. This paper focuses on the environmental perspective, and its correlation with the evolution of the high-rise urban form. Previous studies on urban morphology in terms of environmental and energy performance are reviewed. Studies on "parameterizing" urban morphology to estimate its environmental performance are reviewed, and the possible urban design implications of the study are demonstrated in by the author, by way of a microclimate map of the iconic Shanghai Xiao Lujiazui CBD. The study formulates the best-practice design guidelines for creating walkable and comfortable outdoor space in a high-rise urban setting, including proper sizing of street blocks and building footprint, provision of shading, and facilitating urban ventilation.

Supplier selection is one of the most important activities of a company. This importance is increased even more by new strategies in a supply chain, because of the key role suppliers perform in terms of quality, costs and services which affect the outcome in the buyer's company. In addition, green production has become an important issue for almost every manufacturer and will determine the sustainability of a manufacturer. Therefore a performance evaluation system for supplier and green suppliers is necessary to determine the suitability of suppliers to cooperate with the company. Supplier and green supplier selection is a multiple criteria decision making problem in which the objectives are not equally important. In practice, vagueness and imprecision of the goals, constraints and parameters in these problems make the decision making complicated. The objective of this study is to construct a decision-making process using fuzzy analytic hierarchy process (FAHP) and balanced scorecard (BSC) for evaluating supplier and green suppliers in the manufacturing industry. The BSC concept is applied to define the hierarchy with four major perspectives and performance indicators are selected for each perspective. FAHP is then proposed in order to tolerate vagueness and ambiguity of information. Finally, FAHP is applied to facilitate the solving process. With the proposed approach, manufacturers can have a better understanding of the capabilities that supplier and green supplier must possess and can evaluate and select the most suitable supplier for cooperation.

Vegetative Filter Strip (VFS) is the best management practice which has been widely used to mitigate water pollutants from agricultural fields by alleviating runoff and sediment. This study was conducted to improve an equation for estimating sediment trapping efficiency of VFS using several different regularization methods (i.e., ordinary least squares analysis, LASSO, ridge regression analysis and elastic net). The four different regularization methods were employed to develop the sediment trapping efficiency equation of VFS. Each regularization method indicated high accuracy in estimating the sediment trapping efficiency of VFS. Among the four regularization methods, the ridge method showed the most accurate results according to $R^2$, RMSE and MAPE which were 0.94, 7.31% and 14.63%, respectively. The equation developed in this study can be applied in watershed-scale hydrological models in order to estimate the sediment trapping efficiency of VFS in agricultural fields for an effective watershed management in Korea.

Water is a strategic resource for Singapore due to its small land mass and more than half of the mainland serves as catchment for raw water, including construction sites. Construction site typically involves earthworks and in conjunction with the frequent and intense rainstorm in Singapore, produce runoff of high turbidity due to suspended sediments. The resulting high concentration of suspended sediment in construction site runoff very often leads to aesthetically unpleasant reservoirs and potentially increases the treatment cost of raw water. To mitigate this, the local standard requires the discharged concentration of total suspended solids of construction runoff leaving a construction site to be less than 50mg/l which is a very high standard. This paper will present, examine and discuss particular issues and practices of Singapore's construction industry in meeting this requirement. The focus will be on two areas: Government lead initiatives and industry practices. How the government agencies worked together with the industry professionals to develop a system to ensure meeting of the standard is discussed. In addition, the types of industry practices, including various Best Management Practice to reduce erosion in construction sites and implement effective sedimentation on construction sites are examined.

Wastewater management is increasingly emphasizing economic and environmental sustainability. Traditional methods in sewage treatment plants have significant implications for the environment and the economy due to power and chemical consumption, and sludge generation. To address these challenges, a study was conducted to develop the Intermittent Cycle Extended Aeration System (ICEAS). This approach was implemented as the primary technique in a full-scale wastewater treatment facility, utilizing key operational factors within the standard Sequencing Batch Reactor (SBR) process. The optimal operational approach, identified in this study, was put into practice at the research facility from January 2020 to December 2022. By implementing management strategies within the biological reactor, it was shown that maintaining and reducing chemical quantities, sludge generation, power consumption, and related costs could yield economic benefits. Moreover, adapting operations to influent characteristics and seasonal conditions allowed for efficient blower operation, reducing unnecessary electricity consumption and ensuring proper dissolved oxygen levels. Despite annual increases in influent flow rate and concentration, this study demonstrated the ability to maintain and reduce sludge production, electricity consumption, and chemical usage. Additionally, systematic responses to emergencies and abnormal situations significantly contributed to economic, technical, and environmental benefits.

최근 우주를 둘러싼 국제사회의 표어는 '우주활동의 안전(safety) 안보(security) 지속가능성(sustainability)'이다. 특히 우주활동의 안보란 우주에 대한 안전하고 지속가능한 접근과 이용을 위하여 "우주에 기반을 둔 위협으로부터의 자유"를 말한다. 그리고 우주에 기반을 둔 위협은 다른 인공위성 또는 우주쓰레기와의 충돌 등과 같은 소극적 위협뿐만 아니라 전자파 장해, 우주 및 지상에서의 무기 경쟁, 더나아가 군사적 공격 등과 같은 적극적 위협을 포함한다. 그렇다면 실제로 우주가 군사적 목적으로 이용된 사례가 있는가? 만일 그러한 사례가 있다면 이를 규제하는 국제법은 무엇인가? 우주의 군사적 이용은 국가의 군사체계에 인공위성을 활용하는 우주의 군사화(space militarization)와 우주에 실용무기체계 그 자체를 도입하는 우주의 무기화(space weponisation)로 규정된다. 우주전쟁으로 불리는 걸프전을 비롯하여 코소보전 및 아프가니스탄전에서도 인공위성이 활용되었으며, 최근 들어 우주무기에 대한 연구가 활발히 진행되고 있다. 문제는 우주활동의 대헌장(Magna Carta)인 1967년 우주조약이 지구 주변 궤도에 핵무기를 탑재한 대량파괴무기의 배치만을 금지하고 있기 때문에, 궤도에 대량파괴무기를 제외한 무기의 배치를 포함하여 우주의 군사적 이용이 가능한 지에 대한 논쟁이 일어왔다. 따라서 유엔헌장을 비롯한 우주 관련 유엔 5개 조약의 분석을 통해 이 논쟁에 대한 국제법의 태도를 확인하는 것이 필요하다. 그리고 우주에서 무기배치 금지조약안, 우주활동 국제행동규범안, 우주활동 투명성신뢰구축조치 유엔 정부전문가그룹의 보고서 등과 같이, 최근 국제우주법은 국제법의 점진적인 발전의 중심에 있다. 그러므로 우주의 군사적 이용에 대한 상기 국제문서의 분석도 필요하다. 본 논문은 기존 및 현재 논의 중인 국제 규범에 대한 분석을 통해 우주의 군사적 이용을 규제할 국제 규범의 향후 논의 방향에 대하여 제언한다.
