In the sustainable waste management, the necessity of environmental education which improves acquisition of the knowledge, attitudes and values for the environment is being emphasized to help students make environmentally desirable decision and promote responsible environmental behavior. However, the environmental education in high schools, as a whole, would be susceptible to many problems caused by tile educational administration focusing only on the college entrance examination. Therefore, this study modifies and applies a program using four teaching/learning methods (Investigation study, Internet-based learning, Field work, Issue analysis study) which deals with the sustainable waste management as the learning subject for the environmental education, and tries to find its effects on the students' environmental sensitivity and environmental conservation behavior in high schools. The main results of this study are summarized as fellows. First, the waste management program had little influence on the environmental sensitivity of experimental groups, while it had positive effect on their improvement of the environmental conservation behavior. Second, there were little meaningful effect on general environmental conservation behavior, but there were some significant results to environmental conservation behavior related to the sustainable waste management. In addition, positive results were found in ecomanagement and consumerism, whereas there were no meaningful results about in persuasion and legal action, which were sub-domains of the waste management program. Among the waste management programs, the school waste investigation study had the most positive effect on the students' recognition and solution of environmental problems as well as improvement of environmental conservation behavior. The easiest one of the four teaching/learning methods was the Internet-based learning, while the most difficult one of them was the issue analysis study. Consequently, in order to achieve the goals of the environmental education in the academic field, there has to be selected the most suitable one of the teaching/learning methods and to be applied to the class, according to the detailed objectives and loaming contents for the environmental education.

Background: Despite the rise in the number of domestic indoor climbing gyms, there is a lack of specific hygiene standards and research on the holds installed in them. Holds can act as vectors for microbial transmission through the hands, posing a risk of infectious diseases, especially with damaged skin. Objectives: The aim of this study is to investigate the contamination level and species of microorganisms on holds according to the management methods practiced in indoor climbing gyms and identify effective strategies for reducing microbial contamination. Methods: We investigated factors that may influence microbial contamination of holds, including hold management methods, user information, and hygiene management at three climbing gyms in Seoul. A total of 72 holds were sampled, 18 for each management method of brushing, high-pressure washing, and ethanol disinfection. Samples were cultured on LB and blood agar at 37℃ for 48 hours to calculate CFUs. PCR assay targeting 16S rRNA was carried out to identify microorganisms. Dunn-Bonferroni was employed to see the microbial reduction effect of the management method and the difference in microbial contamination by management method and climbing gym. Results: As a result of microbial identification, microorganisms such as Bacillus, Staphylococcus, and Micrococcus, which were derived from various environments such as skin and soil, were discovered on the surface of the climbing hold. Among the discovered microorganisms, some species had potential pathogenic properties that could cause food poisoning, gastrointestinal disease, bacteremia, and sepsis. All hold management methods were effective in reducing microorganisms (p<0.05), with ethanol disinfection being the most effective (p<0.001). Conclusions: Our results indicate that there are potential pathogens on holds that demand thorough management for microbial prevention. Proposed methods include regular brushing and ethanol disinfection in addition to high-pressure washing with long cycles, which are the existing forms of hold management. Further studies on shoe management are advised to curb soil-derived microorganisms.

Environmental impact assessment (EIA), which predicts, evaluates, and manages the influences on natural landscape, plays a role of monitoring natural resources for systematic management of natural landscape. However, the function of verification and correction of the system is still insufficient and feed-back, one of the most important features of EIA follow-up, has not been introduced in Korea's EIA system yet. As a procedure, it is required to check if the opinions of the evaluators are properly reflected to the outcomes of the project through a reviewing process after assessing environmental impacts of a development project. In reality, despite the awareness about the importance of follow-up inspection of the conformity with, the system mainly focuses on the agreement during the planning stage of the development project and fails to continuously manage after its completion. There have been various preceding studies related to prediction, evaluation, and management of environmental impacts on natural landscape for better management. They primarily dealt with the problems in the EIA process and suggested improvement measures, including directions for institutional development, step-by-step goals, and operation methods, to address the problems which arise in the EIA follow-up process. However, suggested measures are not actively applied with the focus only put on institutional operation, there are virtually no standardized methods to predict and assess landscape changes due to the development project and to manage landscape after the project. Against this backdrop, this study aims to explore the existing methods to analyze the impacts natural landscape and to establish a system where landscape management is continued after the development project. To this end, we will suggest reducing methods according to the predicted changes in landscape for post-project management of natural landscape. Characteristics of reduction methods by project type were examined through reviewing the guide to natural landscape rating and the importance of development project impacts on natural landscape by type of reduction was evaluated through questionnaire for experts. Evaluated types of reduction are classified and presented by characteristics of each development project and content of reduction type.

A construction project's period is limited by the order manufacture. And a construction project is requested a specific place, and has the characteristic to be irregular. Today, construction is to be representative high-cost and low-efficiency. This kind of problems appears in small construction projects more often than large construction projects. According to this facts, we recognized necessity of making practical application in methods of construction management. Also, we suggest application and establishment of integrated responsibility management department, PMIS(Project Management Information System) and Data Base. From now on, methods of construction management could be good opportunities for small construction projects and local construction companies. Therefore, small and local construction companies should try to improve their abilities. Likewise, the countries systematize to constitute the relation laws.

We propose a method to analyze user requirements to design a virtual reality-based risk management system. This paper presents surveys, interviews, prototype evaluation methods, and implementation process. Architectural heritage is easily exposed to natural and artificial dangers caused by various material combinations and structural features. So, risk management of cultural heritage plays a key role in preserving and managing cultural heritage. However, risk management has been carried out through empirical methods using distributed data. This study analyzes user requirements for designing functions and interfaces of VR-based risk management system and evaluates prototypes to overcome the above problems. As a result, most heritage managers wanted a system function to support risk analysis and response. They also found that they prefer 2D information such as existing drawings and photos rather than 3D information. The results of the user requirements analysis derived from this study will be used to create risk management applications.

This paper is designed to find and develop new concepts for the sustainable traditional village in Korea. To this end, it is necessary that concern for the traditional village should diversify and expand, and not concentrate solely on the cultural properties and architecture-oriented historic elements. In consideration of this notion, this paper suggests introduction of maintenance and management as a practical concept for the embodiment of the sustainable traditional village. This paper aims to explore the concrete maintenance and management systems of Korean and Japanese cases, to analyze differences and characteristics between the two nation\\\\`s, and through these comparisons, to suggest sustainable maintenance and management methods for the traditional village in Korea. Primary data was collected by field and interview survey on each village in the two nations several times during about a two year period. The major findings of this paper are presented in three categories--maintenance management frame, maintenance management contents, and necessary principles for progressive maintenance management, and are as follows; In the first step, suggests the basic directions, boundaries, and systems for the maintenance and management of sustainable traditional villages. And in the second step, analyzes the relationship among the contents of maintenance and management methods with focus on the village space, village attraction, and village community. Our results suggests diverse maintenance and management contents for the sustainable village maintenance and management. Finally, the basic principles for the application, and use as valuable tools for sustainable village maintenance and management, are strongly recommended.

Due to the decrease in coastal productivity and deterioration in the quality of ecosystem which result from the excessive overfishing of fisheries resources and the environmental pollution, fisheries resources in the Korean waters hit the dangerous level in respect of quantity and quality. In order to manage sustainable and effective fisheries resources, it is necessary to suggest the potential yield (PY) for clarifying available fisheries resources in the Korean waters. So far, however, there have been few studies on the estimation methods for PY in Korea. In addition, there have been no studies on the comparative analysis of the estimation methods and the substantial estimation methods for PY targeted for large marine ecosystem (LME) For the reasonable management of fisheries resources, it is necessary to conduct a comprehensive study on the estimation methods for the PY which combines population dynamics and ecosystem dynamics. To reflect the research need, this study conducts a comparative analysis of estimation methods for the PY in the Korean waters of the East Sea to understand the advantages and disadvantages of each method, and suggests the estimation method which considered both population dynamics and ecosystem dynamics to supplement shortcomings of each method. In this study, the maximum entropy (ME) model of the holistic production method (HPM) is considered to be the most reasonable estimation method due to the high reliability of the estimated parameters. The results of this study are expected to be used as significant basic data to provide indicators and reference points for sustainable and reasonable management of fisheries resources.

Regarding all methods of decision making as parts of the same subject, one is astounded to find that the field speaks to the practitioners about multicriteria decision making with a multi-forked tongue, different methods give different and conflicting outcomes even for very simple decisions. In this paper, five well-known decision theories are described and used to work out a simple decision to choose the best of three cars. The outcomes turn out not to be the same for all the methods, which is troubling because one would expect unique answers in decision making. Several "meta" criteria that are essential for making a decision theory to make a choice as to which decision approach is best.h is best.
