While heat island has been recognized as an unique environmental nuisance in cities, the phenomenon tends to be regarded as an inevitable side effect on urbanization. Recently the nature of the heat island has been disclosed and efforts for the remedy have been discussed in many ways. Some pioneering actions have been taken to mitigate the strength of the heat island's intensity in several countries. After studies for the heat island and speculations on current pilot policies of 3 different countries has been done, mitigation policies for heat island has been suggested as followings. 1. Preservation of natural topography is essential because latent energy consumption(evapotranspiration) from the site is the single most important factor to mitigate the energy surplus caused by urban heat island. 2. Because current national zoning ordinance or building law can not effectively control the site specific local environment, heat island policy should be established or employed at local level. 3. Incentives for the mitigation should be adopted on the process of implementation because environment is public concern. 4. Wind can easily dissipate energy surplus which is the major driving force for heat island. Therefore local wind, the direction and intensity should be sustained and sometimes facilitated fully through policies.

High rise office buildings represent one of the most energy-intensive architectural typologies. The growth of urban population necessitates sustainable high rise towers that lessen environmental impacts and energy consumption. Among various sustainable strategies, the integrated design is long known to be an important process that has great impact on building's sustainability. The framework for this paper is based on the case study of integrated towers that are located in different climate zones. The paper specifically addresses to what extent climate conditions influence the design of a high rise building and what kinds of the climate integrated design has been implemented. Qualitative case studies were carried out using published data and architectural drawing set. The technical work presented in the paper is based on computer simulation that examines the insolation analysis using hourly recorded weather data. The analysis results revealed that the site and building envelope integration and the site and building service systems have shown the most frequently employed in the integrated towers through the implementation of renewable resource integration, high performance envelopes and sustainable building service systems. Internal comfort and further energy saving in the integrated towers are offered through an automatic building management system. Due to the dynamic climate conditions, integration of building systems requires a sophisticated approach to building sustainability.

Purpose: This study aimed to provide baseline data for implementing advanced life-support for 119EMTs. This is done with an in-depth examination of the emergency care experiences of the 119EMTs on-site and during transportation. Methods: Interviews were conducted with twelve 119EMTs, and the data were analyzed using the phenomenological method. Results: The 34 topics had 19 sub-components and were analyzed according to seven categories: 'A work environment where you cannot focus only on emergency care on-site and during transportation', '119EMTs struggling with manpower shortage', 'Current status of education blocking the upward standardization of 119EMT', 'Implementation of professional emergency care was held back due to the limited legal scope of 119EMT', 'Medical oversight makes it difficult to implement emergency care due to low flexibility', '119EMTs who cannot choose hospital selection and find it difficult to receive help', 'An evaluation system not reflecting reality at all that only leaves high scores'. Conclusion: This study was undertaken to implement specialized emergency care for 119EMTs; not only the necessity of reviewing the expansion of the work scope of 119EMTs but also the necessity of effective 'Medical Oversight system' reorganization raised as well.

The purpose of this study is to search for the ways to diversify Outdoor/Environmental Education Program in the Nature Study Center(NSC), especially for the middle school students. For this study, various research methods such as literature review, questionnaire survey (448 students, 11 middle school teachers, 19 NSC staffs), interview and participant observation are used the process of this study consists of two steps. The first step is to define research questions through pilot survey and the second is to investigate the research questions, in the form of hypotheses through main survey. Nine hypotheses are formulated. Six are related with program elements (educational goals, student characteristics, staff resources, teaching methods, instructional resources, contents). three are related with program implementation process(preplan, implementation, post-evaluation). The hypotheses are tested and alternatives for program improvement are proposed. 1. Educational goals : Educational goals of NSC should be focused on Outdoor /Environmental Education and each NSC should specialize on its own theme. The objectives of every sub-program should be unified toward educational goals. 2. Student characteristics: The Outdoor/Environmental Education Program should reflect student characteristics: sex, urban/rural origins, normal/handicapped, number of visit and so on. 3. Staff resources : Provide qualified staff with professional knowledge and positive attitudes, reeducate staffs periodically, reduce management staff and increase teaching staffs. Provide permanent and well paid position, encourage and give opportunities and the middle school teachers to participate in program. 4. teaching method: Increase outdoor classes two way communication between teaching staffs and students adopt more open ended teaching method so that students can exercise coworks in small groups. 5. Instructional resources: Diversify NSC sites(mountains, coastal areas, urban areas and so on), teaching media (audio/visual equipments, graphic design of signs). Consider design for handicapped and integrate indoor and outdoor educational facilities. Plan nature trails with separate themes, allign nature trail so that it passes through diverse environments. 6. Content : Reflect characteristic site potential specialize on day or night program, on seasonal program, and on site specific social issues(such as interpreting of environmental damages around the NSCs). 7. Preplan: Get Information and know about visiting students in advance. Discuss with middle school teachers and adjust program weeks before visits if many or all of the students had already visited a NSC. arrange a visit to other NSC. Provide an introductory class for the teachers and students before they visit a NSC. 8. Implementation: During NSC visit and classes apply various and appropriate techniques to collect in formation for later evaluation. Improve NSC provided evaluation sheet so as to reflect student characteristic. Compare with formal education and investigate on effects of NSC program. 9. Post-evaluation: Formalize a post-evaluation process and organization. During the winter vacation, develop new programs based on the post-evaluationacation, for the next year. Also, have comparative evaluation meetings of staff from various NSCs during the winter vacation while there is no visitors and classes.

In this paper, we proposed the mathematics learning evaluation system between teachers and students using the web. The proposed web-based evaluation system lets learners make up their lesson in a self-oriented and effective way, by letting instructors diagnose learners level of understanding learned contents and letting learners take part in evaluation as well. The system also lets instructors easily make out items for evaluation by using hangul(word processor) and present them on the web. With the help of this web-based mathematics learning site and mathematics learning evaluation system, learners can perform self-oriented loaming and approach various kinds of problems. In addition, students can check with answers and have feedback on the spot. As a result, students can solve lack of understanding on the learned contents.

Due to muddy water from the highland fields upstream of Soyangho Lake, the Mandae, Gaa, and Jawoon have been redesignated as NPS management areas. This study aims to evaluate the adequacy and supplementation points of the implementation plan by analyzing the operation status of muddy water generation and reduction facilities through on-site investigations by NPS management area to achieve the effective nonpoint pollution reduction goal in the implementation of the implementation plan established in 2020. The SS load calculated based on the survey results from July to October 2019 from 2017 showed a decreasen in 2019 compared to 2017. Both and the Jawoon were analyzed to have decreased. However, the amount of precipitation also decreased by about 27%, so it was judged that the effect of the reduction project was not significant. As a result of the detailed investigation of abatement facilities, about 86% of the 793 facilities installed in the management area were evaluated as 'good'. As a result of a detailed investigation by subwatersheds, subwatersheds 105 and 106 in the Mandae were analyzed as apprehensive subwatersheds. appeared to fall. In addition, it was analyzed that the effect of reducing muddy water in the Mandae district was insufficient due to the high ratio of leased farmers, lack of efforts to reduce turbid water in leased farmland, conversion to annual crops, and neglect of bare land. In the case of Gaa district, although the abatement facilities are concentrated in the upstream, muddy water was also found to be severe.

The rapid change of the culture and art environment is led to new art & cultural education and differences in culture and art education facilities, away from the traditional closed space culture and art education. Phenomena such as plays out of the theater, exhibitions out of the art museum, and pictures taking a walk indicate that cultural and artistic educational facilities can no longer stay in the existing paradigm and are changing along with the changes in the cultural and creative world. Therefore, to develop a site-specific theater education program centered around a specific place rather than a theater or studio, in line with the changing times of cultural and artistic educational facilities, this researcher analyzes Brecht's radio play experiment and the recent performative performance experiment. Furthermore, using the regional and community values of arts and culture education confirmed as the motive for research on site-specific theater programs, I analyze the implementation and application process by experimenting with theater programs out of the theaters and studios. As a prior study, research on site-specific performances is being conducted relatively actively, but earlier studies were dealing only with the Ligna group performance cases are lacking. However, I would like to use the previous research on site-specific performance cases as an epistemological background. As a result of the study, for the place-specific theater program through a total of 10 learners, a text based on a specific place was created that did not depend on traditional literary texts. Through this, the possibility of a site-specific theater education program could be confirmed.
