  • 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.

  • Nitrogen oxides (NOx) in combustion flue gas are currently mitigated by chemical processes such as catalytic reduction, absorption and adsorption. However, development of environmentally sustainable biological processes is necessary in the near future. In this paper, the up-to-dated R&D trend of biological methodologies regarding NOx removal was reviewed, and their advantages and disadvantages were discussed. The principles and applications of bacterial system including nitrification and denitrification and photosynthetic microalgae system were compared. In order to enhance biological treatment rate and performance, the insoluble nitric oxide (NO) should be first absorbed using a proper solubilization agent, and then microbial degradation or fixation is to be followed. The use of microalgal system has a good prospect because it can fix $CO_2$ and NOx simultaneously and requires no additional carbon for energy source.

  • Recently, oystershell wastes cause serious environmental problem and the need for the researches on the recycling of oystershell have been increased and various methods are already in operation. Field plate bearing tests and numerical analysis were performed to investigate the bearing capacity of oystershell filled geotextile gabion which utilized the waste oystershell at the coastal oyster farm site. The waste oystershell mixed soil specimens were prepared for the laboratory test and field test in terms of varying blending ratio of granite soil and oystershell. Based on the cyclic plate load test results, the spring constant, subgrade modulus of ground, and the reinforcing parameters were determined. The field plate load test results indicate that the bearing capacity of the soil ground with the oystershell mixed ratio of 20% is greater than that of the original ground. Two-dimensional numerical analysis was evaluated the expected deformation in the given conditions. Analysis results show a similar characteristics on bearing capacity with the results of the field plate load test. These findings suggest that the oystershells are very promising construction materials for landfill and earth embankment in coastal area.

  • Concern about global environment has been increasing in recent years. Efforts to minimize the environmental impact to the globe as well as human beings have increased, especially in the late twentieth century. The study researches one of the solutions for the environmentally friendly building construction, which can contribute to sustaining the world environment. Assessment and proposals are made for high-rise apartments, one of the most popular construction types nowadays in Korea. Since the volume of high-rise apartment construction is so great, a small improvement in each building will make a great contribution. Assessments are made over the life-span of apartment buildings. A tool named EIAHA (Environmental Impact Assessment for High-rise Apartment) has been made through references from western examples, mainly in the UK. The components of EIAHA include passive design strategies, building materials, energy consumption during building operation and management/maintenance. Although the issues are on a global scale, solutions are sought on regional scale. Korean high-rise apartments are assessed with the tool and suggestions for sustainable development are made mainly for improvement of embodied energy of building materials and the life of buildings.

  • Firstly, the goals and the domains of contents of environmental education was classified in order to systematize the contents of environmental education which would be taught in each subject. According to these goals and domains of contents, the contents of 10 subjects (Korean Language, Ethics, Social Studies, Mathematics, Science, Music, Arts, Physical Practicum(Technology and Heme Economics), English were analyzed. The norms in the analysis of the goals of environmental education by each subject were 4 domains: information and knowledge, skills, value & attitudes, & action and participation. The norms in the analysis of the contents of environmental education by each subject were 11 domains: natural environment, artificial environment, population, industrialization/urbanization, resources, environmental pollution, environmental preservation and measures, environmental sanitation, environmental ethics, environmentally sound and sustainable development(ESSD), and sound consumption life. As a result, it was found that all the 4 domains of goals in environmental education could come true. Furthermore, the goals of environmental education were found to be reached in the subjects of Korean Language, Music, Arts, Physical Education, Mathematics, English, etc., which had been thought to have nothing to do with environmental education. It was also found that the contents of each subject could deal with its own unique environmental contents. The result of this study can keep all subjects from overlapping in environmental contents, and can make the most of each subject's characteristics. Also, the result of this study will be referenced in developing the teaching and learning materials for environmental education according to each subject.

  • In this Century, most of ports have been changing in order to keep up with change of the world. The ports are became larger and integrated with high technology because containers which pass through the ports are sharply increasing. Not to turn over the world wide competition of the ports, a renewal of Bukhang in Busan was promoted firstly in Korea. In this study, final draft renewal plan of Bukhang in Busan at this stage was compared with renewal plan of Haffencity in Germany in order to propose improved renewal plan of Bukhang in Busan. Renewal plan of Haffencity in Germany was very similar with Bukhang in Busan in terms of renewal period and direction. From the results of these comparisons, it was concluded that participation of private enterprise and international capital should be invested. Also, the facility plan of Bukhang was suggested to vitalize citizen's participation and embodimentof renewal plan. Prior to making a development plan enough consideration on the preservation of the environment is needed for the environmentally sound and sustainable development (ESSD). Also Korean tradition and culture should have to be considered in order to create the most Korean appearance.
