From the students' point of view, this study was carried out to find out barriers to environmental conservation practice of secondary school students. According to the questionare and interview with secondary school students on barriers to environmental conservation practice at home, school, society and fellow-relation conditions and in personal psychology, the following findings were resulted. The major barriers to environmental conservation practice are (1) not doing environmental conservation practice of parents, friends and neighborhood, (2) having no interest in environment and environmental problems, (3) dirty and laboriousness of environmental conservation practice, (4) lack of environmental equipments, (5) the shortage of chance and time for environmental conversation practice, (6) lack of the inducement for environmental conservaton from school, (7) little effects of individual environmental practice, (8) a busy life, (9) shortage of the voluntary courage to practice for environmental conservation, (10) lack of compensation on the environmental conservation practice, (11) anti-environmental behavior among friends, (12) urging on edcation of parents. Those barriers related with home, school, society and fellow-relation anti-environmental conditions hold back environmental conservation practice of secondary school students. Those barriers are divided into three closely correlated tipes, (1) unpleasant traits of environmental conservation practice such as cleaning, recycling were linked with personal psychology, (2) lack of the social interest and practice for environmental conservation were linked with personal psychology, (3) the social atmosphere to urge on education was linked with students' busy life and the shortage of chance and time for environmental conversation practice. According to the results, attractive environmental education programs, home environmental education, cooperative environmental conservation programs, and inducements for environmental conservation are reguired of secondary school students to promote environmental conservation practice.

The main purposes of this paper are to determine the major factors influencing visual preference in soundproofing barriers in urban places and to provide the essential information needed in the design process of soundproofing harriers. This paper consists of two phases. The first phase presents photos of the seven types of soundproofing barriers generally seen around the Daejeon area, which were taken from three places for a photo montage. The evaluation of 21 different soundproofing barriers was conducted by college students. The second phase of this paper depicts the analysis process. Firstly, the visual preferences as found from the collected data were evaluated by five semantic degrees. The evaluated data were processed by descriptive test, a correlation test and ANOVA test methods using an SPSS statistical package. 1. Currently, visual preference in soundproofing barriers is low in urban places. Therefore, it is necessary to design visually pleasing soundproofing barriers to improve the visual qualify of urban areas. 2. Soundproofing barriers of mixed wood and acrylic scored the highest among selections while those with aluminium steel scored the lowest. 3. Environmental friendly and transparent conditions should be met to allow soundproofing barriers to be visually pleasing.

Implementation of mitigation options on land is important for realisation of the goals of the Paris Agreement to stabilize temperature at $2^{\circ}C$. In India, the Intended Nationally Determined Contribution (INDC) targets include a forestry goal of creation of carbon sinks of 2.5 to 3 billion tonnes by 2030. There are however, multiple barriers to implementation of forestry mitigation options in India. They include environmental, social, financial, technological and institutional barriers. The barriers are varied not just across land categories but also for a land category depending on its regional location and distribution. In addition to these barriers is the impeding climate change that places at risk realisation of the mitigation potential as rising temperatures, drought, and fires associated with projected climate change may lead to forests becoming a weaker sink or a net carbon source before the end of the century.

The purpose of this study is to review the current state of energy education in Korea and identifies barriers faced by teachers in doing energy education. For this purpose, this study carried out a questionnaire survey targeting energy saving policy research-schools. The results of this research are as follows. First, teachers facing barriers in energy education pointed out the lack of teaching text and students' interest in energy, and work stress as main barriers. Second, teachers facing barriers in energy education rather than teachers not facing barriers are inclined to do more education at Ordinance hour and Jongrye hours. It implies that more energy education textbooks for Ordinance hour and Jongrye hours need to be developed. Third, teachers facing barriers in energy education desire more chances for training program, compared with teachers who do not feel barriers. It implies that opportunities for teacher training program need to be expanded.

Purpose: The purpose of this study was to explore nurses' experience of the role adaptation process and barriers in long-term care (LTC) facilities including nursing homes, daycare centers, and home visit nursing centers. Methods: After in-depth interviews with 13 nurses who were working at the LTC facilities in G province, the data were analyzed using Colaizzi's phenomenological methodology. Results: 17 themes with 6 theme clusters, and 2 categories emerged: nursing role adaptation process in the LTC (role expectation and readiness, role perception and performance, limits of role performance), and barriers to nursing role adaptation in the LTC facility (organizational, situational, and institutional-environmental barriers). Conclusion: The results showed that it is critical to establish the nurses' role in caring for the health of the elderly and maintaining the quality of care in the LTC facilities. In response to the growing demand for quality care in the LTC facilities, more institutional and environmental changes are needed to address the current barriers that prevent nurses from performing their appropriate roles.

Transparent type noise barrier is a desirable facility since it provides a secure view to drivers and passengers. However, reflection from this type of barrier could annoy dwellers on the sides of the road. To reduce reflection noise by transparent type barrier, modification can be made to the shapes on the front side and hence get effects by distortion of sound transmission. To achieve this, we have conducted simulation by which the effects of patterned screens of noise barrier on high-ways were investigated. The reduction effects of reflected sounds were evaluated for swelling, swelling with curved, rectangular and V-shaped screen type barriers, compared to the planar panel. The emitting noise was generated by 6-lane road and the patterned noise barriers had shown the reduction effects, especially in swelling and swelling with curved type for middle height dwellers, and the V-shaped screen type for higher elevation dweller. The swelling-type showed a decrease of 0.7~1.2 dB, performing the best diminution effect among the tested noise barriers.

This study was intended to develop a new measure for environmental education research, named ‘Subjectively Responsible Environmental Behavior(SREB), in order to overcome a few of limitations embedded in the previous measures. The results of the study suggested that there were several barriers for learners to take environment-friendly actions, willingness to act was always stronger than self-reported act and the degree of discrepancy between willingness to act and self-reported act is correlated with perceived effectiveness, perceived difficulty, and expected guilty. In terms of participation, this study defined one of major missions of environmental educators is to help learners to identify and overcome such barriers. A new measure that this study has proposed can be better utilized to evaluate effectiveness of environmental education curriculum or programs and find information necessary for modifying the programs than to assess learners' achievement. Some limitations of the proposed measure were also discussed.

Current research and development of high performance concrete, together with study of phenomena that are pertinent to impact resistance, have lead to a new generation of barriers with improved properties to resist impact loads. The paper reviews major properties and mechanisms that affect impact resistance of concrete barriers as per criteria that characterize the resistance. These criteria are the perforation limit, penetration depth and the amount of front and rear face damage. From the long-known, single strength parameter that used to represent the barriers' impact resistance, more of the concrete mix ingredients are now considered to be effective in determining it. It is shown that the size and hardness of the aggregates, use of steel fibers and micro-silica have different effects on performance under impact and on the resistance. Additional pertinent phenomena, such as the rate and size effects, confinement and local versus global response, are pointed out with their reference to possible future developments in the design of impact resisting concrete barriers.

토석류는 사면 붕괴, 산사태, 홍수 등과 같은 인명 및 재산피해를 수반하는 자연재해의 일종이다. 2006년 7월 집중호우로 인하여 대규모 토석류가 발생하였으며, 이에 따라 고속국도, 일반국도, 철도 등의 국가 기간망이 통제되어 언론에 보도되는 사태가 발생하곤 하였다. 토석류에 대한 연구는 지금까지 충실히 수행되지 않은 것이 사실이다. 원인으로는 예측이 매우 어려웠을 뿐 아니라, 발생위치가 산지에서 주로 발생하였으며 도심지 및 주택가에서 발생하지 않아 국민들에게 부각되지 않았던 이유도 있다. 본 연구에서는 토석류를 방지하기 위하여 사방댐 등의 대책방안이 수립되어 적용되어 오고 있으나, 단점 및 보완점을 개발하여 새로운 기법을 적용하였다. 또한, 계곡부의 특성 및 형상에 따라 다단계의 유연성 시설물을 설치함하여 인명 및 재산피해를 최소화 할 수 있도록 고안하였다. 대상지역을 2개소 선정하여 적용성에 대한 평가를 실시하고 결과를 제시하였다. 연구결과, Site A, B 지역에 토석류 방지시설이 각각 17개와 13개가 설치요구되었다. 향후 토석류에 대한 체계적인 지침 및 방안에 대하여 정립해 나갈 필요가 있을 것으로 생각된다.
