This study examined the effects of RSM (Regional Science education resource Map), developed and provided by Busan metropolitan city Office of Education, at high schools in Busan. Two group of students, who were in the same level of achievement as well as other environmental conditions, participated in this study. Twenty nine of students as an experimental group experienced outdoor activities utilizing RSM, while thirty of students as a control group did not participate in any outdoor activities. The results indicated that compared to the control group of students, the experimental group of students represented a significant improvement in students' environmental attitudes, local ecological interest and eco-friendly behavior. The teachers who guided outdoor activities utilizing RSM suggested that RSM needs to be further subdivided by seasons as well as local districts. They also suggested that RSM needs to be linked with a school curriculum.

Objectives: Outdoor workers are exposed to thermally stressful work environments. In this study, heat stress indices for harbor workers in summer were calculated to evaluate thermal comfort based on a human heat balance model. These indices are Physiological Subjective Temperature (PST), Dehydration Risk (DhR), and Overheating Risk (OhR) according to respective stage of cargo work in a harbor. In addition, we constructed a forecast system to provide heat stress information. Methods: Thermophysiological indices in this study were calculated using the MENEX model (i.e. the human heat balance model), which used as inputs the meteorological parameters, clothing insulation, and metabolic rate for each stage of cargo work in the harbor of Masan over the course of seven days, including a four-day heat wave. The forecast heat stress information constructed for Masan harbor was based on meteorological data supported by the Dong-Nae Forecast from the KMA (Korea Metrological Administration) and other input parameters. Results: According to higher metabolic rate, thermophysiological indices showed a critical level. In particular, PST was evaluated as reaching the 'Very hot' or 'Hot' level during all seven days, despite the heat occurring over only four. It is important in a regard to consider the work environment conditions (i.e. labor intensity and clothing in harbor). On a webpage, the forecast thermophysiological indices show as infographics to be easily understand. This webpage is comprised of indices for both current conditions and the forecast, with brief guidance. Conclusion: Thermophysiological indices show the risk level to health during a heat wave period. Heat stress information could help to protect the health of harbor workers. Further, this study could extend the applicability of these indices to a variety of outdoor workers in consideration of work environments.

In this study, the indoor fine dust concentration in an office of the Korea Knowledge Industry Center was measured for about 80 hours when the concentration of atmospheric PM_2.5 was very high. The effect of the operation of the air cleaner and the forced ventilation system on the indoor PM_2.5 was investigated, and the particle size distribution of the indoor and outdoor particles was analyzed. When forced ventilator and air purifiers were partially used, the indoor PM_2.5 concentrations were maintained between 27.7 ㎍/㎥ and 32.9 ㎍/㎥ when the atmospheric PM_2.5 was 127.7 ㎍/㎥ to 141.6 ㎍/㎥ during working hours. It is more effective to operate the air purifier without operating the forced ventilation system when the concentration of the PM_2.5 is high since the PM_2.5 penetrating the installed filter is continuously introduced indoor from the outside.

The purpose of this study is to examine the degree of appropriateness of using design quality indicators for the educational building, and complements for design quality indicators. For doing this, each items of the Korean educational building design indicator was validated by teachers, school staff and an education officer. First, School Personnel and Teachers considered indicators for the classroom designed for general subjects as being valid. However, in terms of indicators for the outside space, they thought of them as not being valid. In particular, it seemed that school staff would have a passive attitude toward the open of the school facility for the local society. It is judged that there happens an adverse effect caused by the open of the school facility for the local society in the educational environment of the school. Second, Education Office Supervisors thought that eco-friendly indicators, LED lighting, an outer wall, and widows and doors had a high validity. On the contrary, he viewed the validity of a rainwater retention basin as being low, which was likely because he rarely had expertise on the construction. When it comes to the indicator of technology capability, ultrahigh-speed information network was seen as being valid, and the indicator of economic feasibility had high validity on maintenance and durability. Third, compared to groups of Teachers and School Personnel, the group of education officers presented high validity of indicators. Validity of indicators might be differently showed because different items on indicators were measured. However, it is speculated that Education Office Supervisors mostly acknowledged the validity of indicators. Fourth, a majority of Teachers, School staff, and Education Office Supervisors were favor of the system of the evaluation accreditation for school facilities since it played a guide role in improving the quality of school. In order to settle the system of the evaluation accreditation for school facilities, it is most important that institutions in the local society which are publicly reliable should participate in the phase of designing the system of the evaluation accreditation for school facilities. In sum, overall respondents agreed with the system of the evaluation accreditation for school facilities but were aware that reliable organizations in public would need to take part in planning the system of the evaluation accreditation for school facilities from the beginning.

The purpose of weighting traffic management strategies is to reach strategic goal through intended and balanced implementations. The AHP is commonly used technique to derive perspective and strategic goals, and to give priorities to them in a organization. In this study, perspective and strategic goals are derived through surveys and interviews with staffs of a traffic management agency. And then, priority of perspective and strategic goals is performed through the AHP. In this study, three things were identified. Firstly, it was found weighting perspectives such as values for customers, future, activity, and performances were in sequence performed. The value for customers were ranked the first. Secondly, it was found increasing of customer- centric thinking and values of eco- friendly system are the highest weighting in strategic goal. Third, it was found increasing of customer-centric thinking is the most important in headquarters and regional headquarter. But, Values of eco-friendly system is ranked as the most important in opinion of branch office's staffs. It was also identified that depending on the working places, such as headquater and branch offices, the response differs.

This study aims to suggest a direction to develop Korea's certification system by comparing the evaluation items between Korea's G-SEED (Green Standard for Energy & Environmental Design) and Germany's sustainable building certification. A number of eco-friendly building certification systems are being implemented globally. On the other hand, mutually comparable evaluation items have not been suggested up until now. Therefore, international standards have been trying to establish evaluation criteria for eco-friendly buildings, and Germany's sustainable building certification is the first certification standard that has accepted those evaluation criteria. According to the result of comparing Korea's green building certification with Germany's sustainable certification, the green building certification has evaluation items not only on environmentality (62.6%), but also on social aspects (25.4%) and economic aspects (3.0%). This suggests a crucial direction to the development of evaluation items regarding the social and economic aspects of green building certification.

It was proposed to differential technique from established ecological park focused on changing the cognition of nature, wetland ecosystem protection and restoration, and studying by served sound leisure program(nature observation and experience, etc.), in compatible mountain and urban forest near the Urban. Firstly, to achieve this aim, it was carried out delicated research and analysis that were the angle of inclination, trail, fauna, actual vegetation, bird and insect, and then to selected nature trail course and analysis capability through it.. In the basic concept and plan, firstly to make park aid mark and foundation mark, and then to establish the detail programs, nature observation program, management and organization program. This site where valley and mountain coexist was highly capable but whole site was very steep, so usable area is very narrow. To make Woomyeonsan nature ecological park escape from the established wetland type, ecological park and the park of event have to use nature material and introduce visitor. To establish it as the Nature Culture observation park and reflect on forest, valley of Woomyeonsan was divided into three display places; Nature ecosystem Zone, Meditation Zone, Nature Culture experience Zone and Nature Culture observation Center. For satisfying with ecological park aid mark and foundation mark, it was proposed to settle management plan for volunteer control and organization composition.

The demand for e-VTOL aircraft is expected to be increased rapidly in the future as a means of urban transportation due to operating cost reduction, eco-friendliness and convenience of vertical take-off and landing using pilot-aids automation system. However, there are many technical hurdles to be solved in securing safety and certification which are essential for commercialization and urban operation. So far, there is no e-VTOL aircraft that has received type certificate and standard airworthiness certificate due to the technical problems and safety requirement differences with conventional aircraft. The e-VTOL aircraft certification should also meet the equivalent level of safety required by the current airworthiness standards, but there are existing problems in securing safety and meeting current standards. In this study, the e-VTOL's certification problems and technical limitations in satisfying the current standards are presented.

Although the construction of the Nakdong River Estuary Barrage (NEB) improved the water supply in the region, it cut off the longitudinal connectivity of the estuary aquatic ecosystem. Thus, the social demands for opening the NEB have been continuously raised, and the efforts to restore the aquatic ecosystem of the Nakdong River estuary began in 2017. Many fish species have inhabited the Nakdong River estuary. Since their habitat and migration characteristics vary widely, the sluice gate operation considering them is essential for the restoration of the aquatic ecosystem. Therefore, in this study, we monitored the fish species living and migrating in the Nakdong River estuary and analyzed the possibility of smooth movement of for each fish species by calculating the average flow velocity according to the type and the height of the gate opening. Moreover, we selected the target fish species for each month and suggested the sluice gate operation according to the depth of the main habitat to present the measures that are ideal for optimal restoration of the aquatic ecosystem in the Nakdong River estuary area.
