  • The purpose of this study is to reveal the kind of traditional perspectives we can use from the past to create a sustainable society for the future and to contribute to the growing interest in, and concern for, environmentally-sound designs. Such perspectives include ways to sustain naturalistic aesthetic views, elements of architectural design, and ideas for traditional lifestyles. Architecture that used these methods would contribute to a more ecologically sensitive view of man's place within the natural environment. This research was conducted by way of literature reviews; the objects of study were physically extant traditional housing, the composition of the traditional village, and traditional lifestyles. The results of this study indicate that the ecological characteristics of traditional Korean homes originated from a holistic conception of society and nature; this holistic conception has been found lacking in our more modern, western influenced homes. In the past, in order to leave an unpolluted or even healthier natural environment to descendents, it was essential to apply ecological principles. Villages harmonized with nature and houses were designed to utilize sunlight and wind. Their natural construction promoted consciousness of human beings and their symbiotic relationship with nature.

  • An experimental investigation has been carried out on the use of an environmentally sustainable material, bamboo, in the construction of precast concrete structural wall panels. The strength and behaviour of three prototype bamboo reinforced concrete wall panel specimens under two-way in-plane action was studied. The specimens with varying aspect ratio and thinness ratio were tested to fail under a uniformly distributed in-plane load applied at an eccentricity of t/6. The aspect ratio of the specimens considered includes 1.667, 1.818 and 2 and the thinness ratio includes 12.5, 13.75 and 15. The influence of aspect ratio and thinness ratio of bamboo reinforced concrete wall panels, on its strength and behaviour was discussed. Varnished and sand blasted bamboo splints of 20 mm width and thickness varying from 8 to 15 mm were used as reinforcement in concrete. Based on the study, an empirical equation was developed considering the geometrical parameters of bamboo reinforced concrete wall panels for predicting its ultimate strength under two way in-plane action.

  • An environmental problem is the greatest barrier to pursuit of mankinds existence and development. The major traits of this problem are totality and complexity, therefore the finding of environmental problem's solutions is very difficult. The eco-friendly development that pursuing the ecological principles is the direction of environmental problem's solutions. Environmentally sound and sustainable development, deep ecological thought or environmentalism, the following of god's creation order and the old oriental thought are patterns and principles of eco-friendly development. Every creature has one ecological niche from the ecological principles of adoption, competition, evolution, variety, circulation, harmony and equilibrium. Ecological niche means that every creature has ecological status and duty. Therefore finding the mankinds ecological niche is important because it is desirable directions for eco-friendly development to solve environmental problems.

  • Feeding pigs used to be a means of managing domestic resources that may otherwise have been wasted into valuable animal protein. Feeding pigs thus was a form of husbandry. Following recent rapid industrial development, pig rearing has changed from extensive to intensive, but this transformation has been associated with major concerns. The concentration of large amounts of pig manure in small arrears is environmentally hazardous. Moreover, high densities of animals in intensive production systems also impose a health threat for both animals and humans. Furthermore, the use of growth promoters and preventive medicines for higher production efficiencies, such as in-feed antibiotics, also induces microbial resistance thus affects human therapeutics. In addition, consumers are questioning the ethics of treating animals in intensive production systems. Animal welfare, environmental and bio-safe issues are re-shaping the nature of pig production systems. Feeding pigs thus involves not only the consideration of economic traits, but also welfare traits and environmental traits. Thus, a focus on technological feasibility, environmental sustainability and social desirability is essential for successful feeding operations. Feeding pigs now involves multiple projects with different sustainability goals, but goal conflicts exist since no pattern or scenario can fulfill all sustainability goals and the disagreements are complicated by reduced or even no use of in-feed antibiotics. Thus it is difficult to feed pigs in a manner that meets all goals of high quality, safe product, eco- and bio-sustainability, animal welfare and profit. A sustainable pig production system thus requires a prioritization of goals based on understanding among consumers, society and producers and needs to view from both a local and global perspective.

  • The study attempts to assess the level of environmental sustainability awareness in the Kingdom of Saudi Arabia. In the process, the study tries to assess the impact of extracurricular activities in increasing awareness of environmental sustainability. A survey questionnaire was administered to the students of Prince Sattam University and other universities of Saudi Arabia. The questionnaire comprises statements on simple environmental conservation activities, which we come across on a daily basis. Hypothesis testing is used to identify significant differences across different categories of respondents. Further, the method of binary logistic regression is used to analyze the data. Though all the respondents agree that conserving the environment is important still there are significant differences across categories when it comes to believing in and practicing environmentally-responsible behavior. The results show that environmental awareness can be increased using awareness activities on sustainability issues in a University setting. The study concludes that increasing the number of extracurricular activities on environmental topics as only 38% of the respondents reported any activity related to the environment in the past year. The findings of this study suggest that increased awareness of environmental issues can boost the sustainability awareness, which will ultimately lead to a sustainable environment.

  • Coastal development works generally increase the suspended sediment concentration of the ambient water, causing environmental impacts in various manners. The most active measures in three sides have been reviewed for their applicabilities in Korea. Referring to the cases in the USA, the legislation of environmental windows seems to be not proper for Environmentally Sound and Sustainable Developments (ESSD) until sufficient scientific data are obtained to address the individual issues of potential negative impacts. Feedback monitoring can be regarded as the best way for ESSD. Korea also has the basic legal system for the feedback monitoring as well as Environmental Impact Assessments (EIA). However, the frequency, period and parameter of related surveys should be improved for the true ESSD. Moreover, environmental facilities such as environmental dredgers should be widely used for mitigating environmental Impacts caused by coastal development works.

  • The purpose of this study was to analyze the role of perceived market influence, which is an important psychological factor influencing consumer behavior in the market, and explain how consumer beliefs related to the market can affect sustainable consumer behavior. First, this study found that gaps in perceived market influence were statistically significant for age and job. Second, environmental concern, organic food consumption (vegetables and meats), and purchase behavior of organic foods were found to be significantly different by degree of perceived market influence of consumers. The mean values were found to be high for the group having strong perceived market influence. This tendency suggests an association between higher perceived market influence consumers and more environmentally friendly consumer behavior. Lastly, this study used Structural Equation Modeling to analyze the effect of perceived market influence as a moderating variable and mediating variable on the relationship between environmental concerns and consumer behavior toward organic foods. The results show a mediating effect on perceived market influence, but a moderating effect could not be found. This result implies that perceived market influence might indirectly affect consumer behavior when transferring environmental concerns to consumer behavior toward organic foods.

  • 연소배가스에 존재하는 질소산화물의 제거를 위해서는 촉매 환원, 흡수, 흡착 등 화학적 기술이 적용되고 있는데, 장기적으로는 환경친화적이고 에너지 소모가 적은 생물학적 공정의 개발 및 이용이 필요하다. 본 논문에서는 연소 배가스에 존재하는 질소산화물을 제거하기 위한 생물학적 공정의 기술동향을 살펴보고 각각의 장단점을 고찰하였다. 질산화와 탈질 기작을 이용하는 박테리아 시스템과 광합성 미세조류를 이용하는 시스템으로 구분하여 기술의 원리와 현재의 기술 수준을 논하였다. 두 경우 모두 처리속도를 높이기 위해서는 불용성의 일산화질소를 일단 적절한 흡수제에 고농도로 포집시킨 후 미생물에 의하여 분해 또는 고정하는 방향이 바람직하며, 배가스 중 $CO_2$와 NOx를 동시에 고정이 가능하고 별도의 탄소원이 요구되지 않는 미세조류의 활용이 기대된다.
