The purpose of this study is to find out the effects of participation environmental UCC(User Created Content) making program on elementary school students' environmental literacy. Through the questionnaires and the analysis of students' outcomes, the effects of environmental literacy in both quality and quantity was verified. By applying computer programs to make environmental UCC to elementary students, helped them increase their environmental knowledge, and got them to recognize the importance of the environment that surrounds them. Students can find a solution to solve environmental problem from their interaction between the environment and themselves. It could also improve students' ability to think positively. From this research, I hope we require to develop possible programs for various kinds of educational activities based on UCC ones, since we already verified the effects of computer programs to make environmental UCC. The programs to make environmental UCC with learners participated is a kind of good model to reflect the learner's need who is a educational user. Or it could be teaching materials to help meet learner's viewpoint. It can also offer learner-oriented and creative learning and which teachers and learners work together to make a good result and that they make a new wave, instead of being teacher-oriented, which teachers force learners to do something. We can have a feeling of achievement through this and we can expect to enhance both our professional ability as a environmental teacher and the quality of lesson.

The purpose of this study was to analyze characteristics of environmental awareness and environmental worldviews on environmental UCCs which made by 27 pre-service biology teachers, and relationship between environmental awareness and environmental worldviews of them. Environmental worldviews were divided into planetary management worldview, stewardship worldview and environmental wisdom worldview. As for theme fo environmental UCCs, most of pre-service teachers chose themes such as environmental destruction, environmental protection, environmental conservation and coexistence with human and environment. Themes of environmental UCCs were somewhat different between females and males. Female pre-service teachers preferred UCC themes related to human's daily life as a consumer but males preferred to environmental protection. Many pre-service teachers referred that major cause of environmental problem was development of environment. Most of them had envionmental wisdom worldview, and tried to use fear appeal to express ways of solving of environmental problems and envieonmnetal worldviews. After making environmental UCCs, more pre-service teachers had envionmental wisdom worldview. This result implies that it is necessary to develop pre-service educational programs realted to environmental worldview formation.

This study was intended to develop the STS module regarding conservation of water resources, called "A Project for the Conservation of Water Resources". Since each theme consisted of 2 subject activities, they had total 8 subject activities. Developed STS module was applied to 113 male students of 11th grader of D High School in Incheon. After they received 8 periods of the developed STS module, the environmental sensitivity and environmental conservation behavior and the interest of the affective domains related to science were determined. Results were as follows; Four themes of this module were 'What are the water resources?', 'What is a main cause for the water pollution?', 'A drinking water? or non-drinking water?' and 'Making UCC for the water resources'. Since each theme consisted of 2 subject activities, they were for total 8 periods. Developed STS module was found to be appropriate for the STS and they could be applied to the classroom easily. Students who were instructed according to the developed STS module showed that there was a statistically significant enhancement in the environmental sensitivity and environmental conservation behavior and in the area of interest of the affective domains related to science. Students who were instructed according to the developed STS module showed positive responses to the instructional methods by STS. Based on students' interview, they revealed that they were impressed with the hands-on activities and the process of subject activities. Instruction with STS module seemed to be more appropriate way of teaching compared to the traditional way of teaching. However, it will be necessary to develop more modules or programs which could be linked from the elementary school level to the high school level and to use them consistently in order to maximize their effects.

Many social and environmental changes have emerged due to the increasing size of the aging generation. This study explored the current status of the information leisure activity of the aging generation (computer use activity, internet service participation, social community participation and blogging, UCC, etc.) and the need for serious games among elderly consumers. It analyzed the current status of serious game and information leisure span as determined by experts on elderly care at the aging welfare institute. The research methods involved applying content analysis and focus group interviews. The results were as follows: The elderly are willing to enjoy the internet and economics networks. In particular, economic investment, economic news, health, meetings, and communication are the main internet search categories. The results for serious games are less interesting than those for IT participation. The components of usefulness in terms of serious games, as identified by care experts, are simplicity, a user-friendly interface, efficacy, and certainty in using the game device. Care experts recognize that serious games represent a supplementary device to traditional physical and emotional therapy.

This paper describes an investigation to determine whether the activated sludge (AS) process could be used for the treatment of wastewater at the Union Carbide Coporation (UCC) plant in Seadrift, Texas. This plant presently utilizes a waste stabilization pond (WSP) system for treatment of the wastewater. The treatment system consists of an in-plant primary WSP and two off-plant WSPs (secondary and tertiary WSPs), run in series. The total hydraulic detention time of the WSP system is approximately 150 days. Several laboratory-based treatability studies have been conducted to evaluate the performace of the WSP system and the degradability of specific chemical compounds. From an additional study, it was determined that the WSP system was stressed and occasionally operating near the limit of its treatment capacity. The existing primary WSP plays an important role in the overall treatmemt system, because it not only functions as a pH and organic-strength equalization basin, but also serves as a "preconditioning" basin by fermenting high strength organic wastes to volatile organic acids for subsequent degradation in the escondary WSP. However, in view of pending RCRA legislatin conerning the "proposed organic toxicity characteristics limits" (40 CFR Part261: Federal Register, July, 1988), it is possible that the primary WSP will have to be abandoned in favor of alternative treatment options. Therefore the main purpose of this study was to perform activated sludge treatability evaluations for the development of an alternative to the existing primary WSP treatment ststem. In addition, another purpose was to determine the degradability of bis(2-chloroethyl)ether (Chlorex or CX) and benzene(BZ) in the activated sludge process. The presence of these two chemicals in the wastewater of the plant prompted the question of whatedether they could be degraded in an activated sludge system.

Industrialization and urbanization are the two phenomena that are going relentless all over the world. The consequence of this economic success has been a massive increase in waste on one hand and increasing demand for suitable sites for construction on the other. Owing to the surplus raw materials and energy requirement needed for manufacturing synthetic fibers, applications of waste fibers for reinforcing soils evidenced to offer economic and environmental benefits. The main objective of the proposed work is to explore the possibilities of improving the strength of soil using fly ash waste as an admixture and Human Hair Fiber (HHF) as reinforcement such that they can be used for construction of embankments and land reclamation projects. The effect of fiber content on soil - fly ash mixture was observed through a series of laboratory tests such as compaction tests, CBR and unconfined compression tests. From the stress - strain curves, it was observed that the UCC strength for the optimised soil - flyash mixture reinforced with 0.75% human hair fibers is nearly 2.85 times higher than that of the untreated soil. Further, it has been noticed that there is about 7.73 times increase in CBR for the reinforced soil compared to untreated soil. This drastic increase in strength may be due to the fact that HHF offer more pull-out resistance which makes the fibers act like a bridge to prevent further cracking and thereby it improves the toughness which in turn prevent the brittle failure of soil-flyash specimen. Hence, the test results reveal that the inclusion of randomly distributed HHF in soil significantly improves the engineering properties of soil and can be effectively utilized in pavements. SEM analysis explained the change of microstructures and the formation of hydration products that offered increase in strength and it was found to be in accordance with strength tests.

북동중국해 코아 퇴적물중 희토류 원소(REE) 함량을 분석하여 REE함량의 분포양상을 파악하고 퇴적물 기원지를 추적하였다. 북동중국해로 퇴적물을 공급하는 한국 강(금강, 영산강 등사 중국 강(황하, 양자강 등)에서 유출된 퇴적물 중 REE함량도 분석되어 한국/중국 강에서 유출되는 퇴적물 중 REE함량의 전형적인 분포양상이 구해졌다. 상부지각 중 REE 함량으로 정규화 된 중국 강과 한국 강 퇴적물 중 REE 함량의 분포양상은 각각 중간 희토류 원소(MREE)와 가벼운 희토류원소(LREE)가 부화된 형태로 나타났다. 중국 강 퇴적물에서 나타나는 REE 함량의 분포양상은 "C-type" 즉 MREE가 부화되어 가운데가 불룩한 형태이고, 한국 강 퇴적물에서 나타나는 REE 함량의 분포양상은 "D-type" 즉 LREE가 부화되어 원자번호가 증가함에 따라 직선적으로 감소하는 형태를 보인다. 북동중국해 코아 퇴적물중 REE 함량의 주요 제한인자는 LREE가 부화되어 있고 연구해역 인근 어디에나 분포하는 모나자이트$((Ce,\;La)PO_4)$로 해석된다. 한편, 북동중국해 퇴적물 중 REE함량의 분포양상은 C-type과 D-type의 중간 형태를 보인다. 이러한 중간 형태에 근거할 때, 현재는 대륙붕 환경이지만 과거에는 강 하구였던 북동중국해의 퇴적물은 한국 강과 중국 강에서 유출된 퇴적물의 혼합체로 판단된다.
