The latest development of the submarine oil field and the deep-sea explorer, FPSO is commonly proposed and used for offshore oil production. And because the fundamental requirement of FPSOs to remain moored at their position, they are unable to avoid severe weather and environment. FPSO normally operates head to the weather, and sensitive equipment located the exposed area will be influenced by green water damages, the damages may occur to both onboard equipment and topside structures with resulting risk to personnel. In this paper, the main focus considers the physical structures of green water protector in order to preserve topside structures, equipment and personnel from green water.

Architecture has a large influence in the environment and human health. Therefore eco-friendly concept and sustainable development are important in Architectural field. This study aims to analyze impact of green building rating system on an apartment housing CO₂ emission using multiple regression analysis. But in this result, green building rating system has no effect on CO₂ emission. So, future study is required to analyze factors of green building rating system on the CO₂ emission.

The construction of green building has distinct charicteristics by work classification by applying green technologies. Thus if the new technologies are applied to construction, unskiiled worker can experience construction time delay, reconstruction occurrence and quality decrease because of mistakes during the construction and work progress. For this background, we establish the work progress manual to secure quality and performance during the construction phase of green building and provide method to be used in the construction sight operation.

경전철 차량은 1MW이상의 전력을 요구하기 때문에 단일 인버터 시스템으로 구현할 경우 시스템 부피 및 비용 증가, 효율 감소 등 문제점을 가지게 된다. 이러한 이유로, 수 kW급 인버터 스택을 병렬로 구성하여 대용량 시스템을 구현한다. 본 논문에서는 이러한 대용량 인버터 시스템을 구성하는 스택 개발 사례를 보여주고 있다. 실험을 통하여 개발한 무선급전용 인버터 스택의 성능을 검증한다.

The purpose of this study was to investigate the preferences and utilization of green tea and its products for adults living in Chonbuk area. Self-administered questionnaires were collected from 388 (117 male, 271 female) subjects. who were classified into 5 groups by age. Data were analysed by chi-square and ANOVA. The results can be summarized as follows. On the investigation of preferences, there was a significant difference between and among the age groups(p<.001). More than 20% of the subjects in the $20{\sim}29$ years group preferred coffee and juice. A half of the elderly over 60 years preferred a kind of green tea. The frequency of green tea drinking was not significantly influenced by age. Drinking green tea less than once a day was replied by 59.0% of the subject of whom 44.3% drank the green tea at home. and 42.0% got information about green tea from TV or radio. Regarding the satisfaction with products using green tea, 62.6% of the subjects responded only 'mediocre.' The brown rice-green tea was marked to be the highest in terms of recognition among all kinds of products. The green tea-related products were rated higher by the elder group. In conclusion, future research should focus on the development of green tea and its products in accordance with the consumption pattern in each age group.

The "Eco-friendly", "Green" concepts was began around 1992 after the Rio Environmental Summit, and the need for sustainable development globally widespread. The green building certification system was began around 2000 and the concept of green building was started in the late 1990s. The green building, which welcomes a period of radical change, is for the survival of the Earth "climate change" and reducing energy consumption in building sector. In this architecture of eco-friendly concept, the green building is rapidly expanding and existing as a ecological environment preservation. Moreover, the realization of zero energy house is to mandate for new buildings in 2025. The aim of further eco-friendly is through the prior ecosystems to restore and product energy for the 9 Green Building model houses in this paper. Building in the concept of ecology is to show about change into 7R's from the 3R's. The "Reduce", "Reuse", "Recycle" consisting of "3R's" is correlated with the traditional to the present Green Building Design. U.S. NCARB (National Council of Architectural Registration Boards) change into the concept of 7R's as "Receive", "Restore", "Respect" and "Remember", added to "3R's". In this paper, the 9 Green Building model houses do not meet the criteria of 7R's. But, the Green Tomorrow of Samsung C & T Corporation meet the 6 criteria for 7R's. This company is most comfortable at low carbon Green Building model houses. Conclusionally, introduction of eco-friendly technologies and amenities for the health of human and natural community life is to advance eco-friendly construction and enhance brand value of housing. By the way, The problem of eco-friendly architecture is initial investment and maintenance. Therefore, eco-friendly architecture and government has to try solving of this difficulty.

Elementary/secondary school must make the scheme for the Low Carbon Green Growth embodiment because of the environmental problems and the Low Carbon Green Growth Policy for responding to global environmental crisis. This paper proposes a plan to make green elementary/secondary school model through the educational information. It divides into 'Greening of IT Information Resources' and 'Greening of Education Environment' through the educational information'. It is expected to embody Green School if these projects are realized to the elementary/secondary school. 'Greening of IT Information Resources' suggests the guideline necessary to the introduction of IT products, the method to abandon considering recycling IT products and environmental information infrastructure model. 'Greening of Education Environment' proposes the IT green practice method for teachers and students to keep and shows the practice of various educational information service to seek a conversion to low carbon education environment. It is expected to embody Green School if these projects are realized to the elementary/secondary school.

Worldwide organizations use the benefits offered by Cloud Computing (CC) to store data, software and programs. While running hugely complicated and sophisticated software on cloud requires more energy that causes global warming and affects environment. Most of the time energy consumption is wasted and it is required to explore opportunities to reduce emission of carbon in CC environment to save energy. Many improvements can be done in regard to energy efficiency from the software perspective by considering and paying attention on the energy consumption aspects of software's that run on cloud infrastructure. The aim of the current research is to propose a framework with an additional phase called parameterized development phase to be incorporated along with the traditional Software Development Life cycle (SDLC) where the developers need to consider the suggested techniques during software implementation to utilize low energy for running software on the cloud and contribute in green computing. Experiments have been carried out and the results prove that the suggested techniques and methods has enabled in achieving energy consumption.

The standard method for somatic cell counts in goat milk is the direct microscopic method after a pyronin Y-methyl stain. It has been reported, however, that are found to differ by measuring methods, but. A total of forty eight goat milk samples from eight farms were compared by pyronin Y-methyl stain, ADAM-SCC in National Institute of Animal Science, and Somacount 500 in Chungbuk Veterinary Service. The average SCC of the samples was $7.3{\times}10^5$ cells/mL by pyronin Y-methyl stain, $4.9{\times}10^5$ cells/mL by ADAM-SCC, and $11.6{\times}10^5$ cells/mL by Somacount 500. The correlations between the methods were not significant. SCC measuring equipment should be developed for reducing the SCC in goat milk, and pyronin Y-methyl green stain for estimating SCC in goat milk should be included in NVRQS Notice for livestock products processing and composition standards.
