  • The trend toward intensification of livestock raising, confinement in barn has increased in recent days. The move toward concentrated animal feeding operations reduces per unit costs and permits farmers to better earnings in spite of fluctuation in hog prices. However, this also results in outbreaks of a lot of animal wastes and odorous compounds. Emissions of these malodorous compounds produced from concentrated animal feeding operations have become a concern for both public and regulatory agencies and are causing the complaints of residents in rural area. For competitive sustainable swine production industry, odor management plans systematically identify potential odor sources, determine control strategies to reduce these odors, and establish criteria for implementing these strategies. Since, the malodor originates from microbial activities involving a variety of microbes, understanding the characteristics of the microflora present in swine manure is essential for developing effective odor control techniques. This paper reviews the available information in the literature related to the types of bacteria in swine manure, the potential odorous compounds associated with different bacterial genera, and the corresponding techniques used to control odor based on microbiological principles.

  • Since the Fukushima Daiichi accident in 2011, concerns for the safety of multi-unit Nuclear Power Plant (NPP) sites have risen. This is because more than 70% of NPP sites are multi-unit sites that have two or more NPP units and a multi-unit accident occurred for the first time. After this accident, Probability Safety Assessment (PSA) has been considered in many countries as one of the tools to quantitatively assess the safety for multi-unit NPP sites. One of the biggest concerns for a multi-unit accident such as Fukushima is that the consequences (health and economic) will be significantly higher than in the case of a single-unit accident. However, many studies on multi-unit PSA have focused on Level 1 & 2 PSA, and there are many challenges in terms of public acceptance due to various speculations without an engineering background. In this study, two kinds of multi-unit Level 3 PSA for multi-unit site have been carried out. The first case was the estimation of multi-unit risk with conservative assumptions to investigate the margin between multi-unit risk and QHO, and the other was to identify the effect of time delays in releases between NPP units on the same site. Through these two kinds of assessments, we aimed at investigating the level of multi-unit risk and understanding the characteristics of risk in a multiunit context.

  • The purpose of this study was to explore what kinds of science communication are ongoing in formal and informal settings for learning about nuclear energy, which is very important issue domestically and internationally. The researchers collected and analyzed data from science textbooks at elementary and middle school levels, from exhibitions in Y informal hall that belongs to one nuclear power plant, and from 40 bestselling books about nuclear energy in order to explore the kind of science communication. The same process was used to explore Japanese case so that we could compare the results with Korean cases and draw implications for enhancing science communication about nuclear energy. The science communication of nuclear energy in Korea included implicit and indirect content espoused in science textbooks; two opposite views displayed in bestselling books, and positive aspects mainly displayed in exhibition of information hall in nuclear power plant. It is suggested that both direct and explicit science communication along with the neutral viewpoints including positive and negative ones be provided for the public to form a good understanding of nuclear energy.

  • 2005년 1월 민간투자법 개정과 함께 도입된 새로운 민자사업방식인 BTL(Build-Transfer-Lease) 방식은 최근 2년간 11조원 규모로 성장하였으며 그 대상 시설도 확대되고 있다. BTL시장이 확대되고, BTL방식이 새로운 공공 조달시스템으로 자리매기 하면서 건설시장에 PM사(社)라는 새로운 비즈니스 형태가 등장하였다. BTL사업에서 중요한 역할의 한 축을 차지함에도 불구하고 BTL시장의 역사가 짧아 PM사에 대한 이해는 그다지 높지 않고 관련 연구 역시 아직은 미진한 상황이다. 본 연구에서는 BTL사업 PM사 특성을 정체성, 주요 고객, 활동 시기, 업무, 단계별 역할 특징, 책임의 여섯 가지 관점에서 분석하였으며, 이를 통해 PM사에 대한 종합적인 이해를 높이고자 하였다.

  • 최근 국내에서 대두되고 있는 도시재생 개발사업은 신도시 및 기존 시가지를 중심으로 공공기관의 주도하에 이루어지고 있다. 이러한 개발사업들은 사전 평가 단계에서의 위험요인 관리가 사업의 성공과 부가가치 창출에 중요한 요인임에도 불구하고 안전관리 수준에서 머물고 있다. 이는 위험요인들을 분석할 수 있는 다양한 위험 분석 기법들에 대한 부정확한 이해 및 그 중요도를 파악하지 못하고 있으며, 단계별 적절한 분석 기법의 적용이 미흡하기 때문이다. 따라서 본 연구에서는 개발 사업에 대한 전반적인 이해와 개발 사업 사전평가 단계에서의 구성 및 정의, 사전평가 단계에서 적용될 수 있는 위험분석기법들에 대한 정의 및 분석을 통해 사전평가 단계에서 나타날 수 있는 다양한 위험요인들을 보다 효과적으로 관리할 수 있는 위험분석기법들을 마련하고자 한다.

  • This study deals with the participatory design process of renovating a children's park. The process should proceed with two major elements. Firstly, the children's park should be designed from the perspective of children. Secondly, it should be designed in consideration of the context of the community. This study is divided into two parts. First is the review of theory concerning the meaning and roles of the children's park as a community space, the importance of children's participation in the design and the participatory method of the children. The second is the case study. The site for the case study is Ssial Park in Nowon-Gu, Seoul. The entire process of the case study is with community participation, from identifying the park's problems to the actual construction. At every step, through the participatory programs, the community participates in the decision making. In addition, mutual understanding among participants is pursued through diverse means of communication. The following results of the case study were found. Firstly, diverse participatory programs and the active trial to enable the community to communicate contribute to the sense of ownership and responsibility concerning the park Secondly, the community can negotiate the differences in opinions without needing the help of experts. Of course, there are limits in the case study, such as the fact that the community organization, which is the core of communication and maintenance concerning the park, is not organized through the process of a case study. Another is that more diverse methods, which inform all community members of the participatory process, should have been used.

  • This study examined understanding and attitude of sustainable development(SD) of 38 college students in a nuclear power plant construction after education for sustainable development(ESD) through panel discussion. The results were as follows: First, after lesson 66% of students were expected that SD is possible if scientific technology is developed and a frugal life for the protection of environment is carried out. However, the remaining students regarded SD as an ideal concept, because they thought it is not possible to pursue environmental sustainability and socio-economic development simultaneously. Second, students' opinions in the evaluation of constructing a nuclear power plant in three aspects(environment, society and economy) before and after panel discussion were changed as follows; 1) After panel discussion, the objectors increased to 21% in economic evaluation, while the supporters increased to 11% in environmental evaluation. 2) Students majoring in engineering or natural sciences changed their opinions to agree in environmental evaluation because they considered a nuclear power plant safe and eco-energy. However students majoring in social science/business or liberal arts/arts changed their opinions to disagree in economic evaluation because they considered a nuclear power plant as high-cost energy when assessing danger-accidents cost, public consensus cost, operation and maintenance cost, and waste disposal cost. 3) This change of decision-making in students majoring in social science/business or liberal arts/arts after panel discussion was statistically significant(p<0.05). Implications of panel discussion as a teaching and learning method in ESD are also discussed.

  • This paper considers the effect of "comprehensive rural community improvement project" in terms of three factors - physical environment, rural tourism, socioeconomic and analyzed the path effect leading to the final outcome - the quality of life of residents, using covariance structure analysis. By doing so, this study looks into why residents prefer the improvement of a physical environment that takes a public nature. The analysis showed that the socioeconomic effect did not have an immediate impact on the improvement of quality of life of residents at a significance level of 5%, whereas the improvement of physical environment had a static effect on the quality of living at a significance level of 1%. Residents' preference for "hardware" or physical environment may be attributed to lack of their understanding of human factors such as social capital. However, analyzing the impact of specific contents of the project on performance, it is found that as projects fail to generate a tangible socioeconomic effect, residents strategically prefer the repair of their physical environment such as public facilities that directly affect their daily lives, so that they can maximize an improvement of the quality of living. Hence, this study suggests that instead of attributing the failure of rural community development projects to residents, macroscopic problems of rural communities and specific contents of projects should be dealt with before the success of any project can be discussed.

  • In this paper, we proposed "Future Design and Success Engineering in Global Society by Self-Innovation" (an abbreviated name: FDSE). We started to make a small experiment between Korea Maritime University and Yamagata University at the current year. After inspecting the results, especially, successful and unsuccessful points in our lecture, we have to develop the strong points and amend the week points, through making the analysis of success-failure, which is his favorite management method. We have to level up the contents of our work in the future. The students for this lecture would learn from experiences of "the common knowledge (common field of discussion)", held common languages, common thought, common system. They filled up the blanks of "The Matrix Frame" which is mentioned in the previous report, and they expressed their own way of life (work, study). As a matter of course, their personal private affairs must not be made public. It is quite happy that the cultural, economical exchanges between Korea and Japan are now in full flourish and people do a lot of traveling each other. However, if this project will start on the educational global standard, we have a world-wide significance. Moreover, we can promote goodwill between Korea and Japan, and also we can contribute to a better international understanding and the peace of the world by students in both Universities. We hope that candidates for this lecture will have a rounded personality and be a life worthy of human being for realizing Self-Actualization in "Motivation and Personality" by Abraham Maslow.
