The purpose of this study was to investigate the effects of physical environments change on children. Specifically, this study investigated the effects of a newly designed elementary school environment to implement open education on elementary school students. The changed environment was improved in various aspects including architectural type, the number of space types, layout, shape of the building, and color planning. This study showed evidence of interaction between aspects of the physical environment and the actual behaviors of children. The impacts of change in physical environment, more specifically, on children was confirmed by the study. Therefore, this study can be used as a basis to insist why physical educational environment needs improvement, to insist importance of physical educational environment and to justify importance of physical environment in educational setting.

The purpose of the Environment Design (ED) for Main Control Room (MCR) of Nuclear Power Plant (NPP) is to provide and create an optimal working space to be free from physical, physiological and mental stress as well as environmental discomfort, based on the previous environment design experiences and to recommend the best ED including the color, the lighting and the interior design. Environment Design consists of three main areas: Human factor engineering design, Interior design with color design, and Lighting design. These design areas have been interactively cooperated in a way that each design specialist would share the objectives and concepts of the Environment Design for MCR. The specialists for Human Factors Engineering design had a corporative role in such a way to provide the guidelines for MCR design suitability of Interior and Lighting design considering the Human System Interface (HSI) safety concerns. This paper describes fruitful efforts to create the best fit for MCR ED among several design proposals with the design recommendations, impacts, and contributions to NPP environment.

Sustaining future wheat production is challenged by anthropogenically forced climate warming and drying led by increased concentration of greenhouse gases all around the globe. Warming stresses, originating from the elevated $CO_2$ concentration, are continuously reported to have negative impacts on wheat growth and yield. Yet, elevated $CO_2$ concentration, despite being disparagingly blamed for promoting warming, is also associated with a phenomenon called $CO_2$ enrichment; in which wheat yield can improve due to the enhanced photosynthesis rates and less water loss through transpiration. The conflicting nature of climate warming and $CO_2$ enrichment and their interplay can have specific implications under different environments. It is established form the field and simulation studies that the two contrasting phenomena would act severely in their own respect under arid and semi-arid environments. Wheat is a dietary staple for masses in Pakistan. The country's wheat production system is under constant stress to produce more from irrigated agricultural lands, primarily lying under arid to semi-arid environments, to meet the rapidly growing domestic needs. This work comprehensively examines the warming impacts over wheat yield and water productivity (WP), with and without the inclusion of $CO_2$ enrichment, under semi-arid environment of Punjab which is the largest agricultural province of Pakistan. Future wheat yields and WPs were simulated by FAO developed AquaCrop model v 5.0. The model was run using the bias-correction climate change projections up to 2080 under two representative concentration pathways (RCP) scenarios: 4.5 and 8.5. Wheat yield and WPs decreased without considering the $CO_2$ enrichment effects owing to the elevated irrigation demands and accelerated evapotranspiration rates. The results suggested that $CO_2$ enrichment could help maintain the current yield and WPs levels during the 2030s (2021-2050); however, it might not withhold the negative climate warming impacts during the 2060s (2051-2080). Furthermore, 10 - 20 day backward shift in sowing dates could also help ease the constraints imposed by climate warming over wheat yields and WPs. Although, $CO_2$ enrichment showed promises to counteract the adverse climate warming impacts but the interactions between climate warming and $CO_2$ concentrations were quite uncertain and required further examination.

This study was conducted to examine the recent developments in timber certification schemes at global level such as FSC certification and ISO 14001 system and to analyze their potential impacts on the Korean forest products trade. Data and information on standards and procedure of timber certification and certified forest lands were collected from relevant papers, statistics and reports published by regional and international organizations. In order to analyze the impacts on the Korean forest products trade, questionnaire survey to the affected parties was conducted on acknowledge of key words relating to environment and trade and on the additional amount of willingness to pay for a labeled timber from environmentally sound and sustainably managed forests. Quantities of certified timbers supplied would continue to increase due to lots of timber certification schemes developed and implemented at national, regional and global levels and growing interests in certification from many countries. Demand for certified timbers, however, is far from clear at this stage. The deciding factor would be consumer reaction to the certified products. In the short run, the timber certification would have a little impacts on forest products imports into Korean markets since domestic purchasers do not have much interests in environment related trade measures and their willingness to pay price premiums for certified timbers is not high. However, it could be expected that timber certification has negative impacts on exports of forest products, such as flooring and plywood, to developed European markets where timber certification is used as a trade barrier.

Recently, Ghim and Son (1993) compared the air quality impacts of two point sources P1 and P3 in Seoul in the first quarter of 1988, whose emission rates were 99.9g/s and 49.4g/s, and whose stack heights were 75m and 21m. They said that higher concentrations from P3 in the nearby area were responsible for shorter stack height of P3. But concentrations were not raised so high only because the stack height was reduced from 75m to 21m. Volume of exit gas from P3 was also much smaller than that from P1.

On June 5, 2008, the "Act on Special Cases Concerning the Simplification of Authorization and Permission Procedures for Industrial Complexes" (Act No. 9106) was enacted. When it was implemented in August 2008, many industrial complex development projects were established, and the number of industrial complexes growth rates of 3-6% during 2003-2007 rose to around 15% in 2008. With the increase in industrial complexes, the environmental impacts of individual projects were examined, but comprehensive regional reviews of environmental impacts were not undertaken. In this study, we determined changes in air quality by applying the industrial complex development plan that completed the consultation at the end of 2010 to assess the comprehensive regional environmental impacts and presented the adequacy review plan for future industrial development plans based on the study's results. When considering these industrial complex development plans, emissions in North Jeolla and South Chungcheong Provinces and Daegu City have increased significantly. Air quality analyses showed that the 24 h mean $SO_2$ concentration in Daegu increased by more than 50% in summer compared to air quality concentrations in summer. The 24 h mean $PM_{10}$ and $NO_2$ concentrations increased by approximately 12 and 30%, respectively, in North Jeolla Province in summer. Areas exceeding the air quality standard for 1 h mean $O_3$ concentration increased by more than $3,500km^2$. Based on the above analysis, changes in air quality should be anticipated through a comprehensive evaluation of long-term development plans. Furthermore, control of air quality in accordance with the development of future industrial complexes is possible.
