The Third Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) concluded that many collective observations gave a aspect of a global warming and other changes in the climate system. Future earth observation using satellite data should monitor global climate change, and should contribute to social benefits. Especially, human activities has given the big impacts to earth environment This is a very complex affair, and nature itself also impacts the clouds, namely the seasonal variations. JAXA (former NASDA) has the plan of the Global Change Observation Mission (GCOM) for monitoring of global environmental change. SGLI (Second Generation GLI) onboard GCOM-C (Climate) satellite, which is one of this mission, is an optical sensor from Near-UV to TIR. This sensor is the GLI follow-on sensor, which has the various new characteristics. Polarized/multi-directional channels and 250m resolution channels are the unique characteristics on this sensor. This sensor can be contributed to clarification of coastal change in sea surface. This paper shows the introduction of the unique aspects and characteristics of the next generation satellite sensor, SGLIIGCOM-C, and shows the preliminary research for this sensor.

The work describes an assessment of the major air pollutants, $NO_2$, $SO_2$, CO, $O_3$, $NH_3$, coarse and fine particulate matter ($PM_{10}$, $PM_{2.5}$) in ambient air in and around a 3 million tonne Petroleum Refinery and the possible impacts on a pristine area marked by the presence of the world-famous Kajiranga National Park, a world heritage site and habitat for the most number of one-horned rhinos in the world. The Refinery is at an aerial distance of 20-25 km from the wildlife habitat. The assessment is based on regular monitoring at four stations around the Refinery and one station near the National Park. Heavy rains during June to August influence the pollutant concentrations while at other times of the year, large traffic volume adds to the pollutant concentrations that peak during November to March, the dry months of the year. Correlation analysis by scatter technique is utilised to obtain the enhancement ratios to predict the variations in the concentrations of the pollutants and their spatial distribution. Computation of air quality index (AQI) indicates that the coarse and the fine particulates in the ambient air could be a major hazard to wildlife in the area.

Prior research in medical service field have mainly focused on service quality, satisfaction, and choice attributes of hospital. However, a little research has been done on "Which service quality attributes are more preferred by customer motivation(customer regulatory focus)". This study examines how regulatory focus affects the structural impact relationships of service quality and emotion(quiescence) on perceived value in medical service context. Especially, this research draws the moderating effects of regulatory focus between medical service quality, emotion, and perceived value. The Results were summarized as follows: The relative impacts of medical service quality on customer emotion are different depending upon the regulatory focus. Hospital reputation is shown to be more important factors in prevention-oriented customer, while physical environment is the case in promotion-oriented customer. The relative impacts of medical service quality and emotion on perceived value are different depending upon the regulatory focus. Hospital reputation, convenience, and accessibility are shown to be more important factors in promotion-oriented customer, while physical environment is more important in prevention-oriented customer. Also, emotion has a positive influence on perceived value in prevention-oriented customer, whereas the effect of emotion is not significant in promotion-oriented customer.

This study was conducted to provide information which will be useful for managing the forest trails effectively. To investigate users' attitudes toward the forest trail construction and use, a questionnaire survey was employed in the Jirisan Dulegil. As the results, most of the respondents perceived that the Jirisan Dulegil have positive impact economically and socio-culturally on community growth. Contrastively, a negative perception existed in the environmental aspect. The users' satisfaction level regarding the Jirisan Dulegil appear to be positive. Users' satisfaction level regarding use services provided in community boundary was evaluated relatively lower. In this point of view, trail use service system provided in the community should be reconsidered for effective forest trail management.

In agriculture, the rice is the one of important things. Many farmers and scientists have long tried to increase the yield of rice. So many technologies have been developed these days. One type of technology has given rise to a host of concerns and questions, namely Genetically Modified Organisms (GMOs). The increasing cultivation of GM crops has raised a wide range of concerns with respect to food safety, environmental effects and socio-economic issues and now commercially planted on about 100 million hectares in some 22 developed and developing countries. The scientific evidence concerning the environmental and health impacts of GMOs is still emerging, but so far there is no conclusive information on the definitive negative impacts of GMOs on health or the environment. Nevertheless, public perceptions about GMOs in food and agriculture are divided with a tendency toward avoiding GM food and products in many developed and developing countries. Also Korea is one of that country and is not allow the GMOs now. So I studied whether these GMOs are actually dangerous for environment and whether there are differences in cultivar characteristics such as germination test with TTC tetrazolium, germination test in frozen soil and gene-flow test with glufosinate and strip-bar test. With these experiments, we evaluated the agricultural safety of GM rice and to identify and assess environmental risks.

Interest has been growing worldwide in unconventional natural gas that has become an increasingly important source of energy in the world. Unconventional gas development, including shale gas, generally involves a larger environmental impact, compared to conventional gas development, due to its intensity and scale of the operation. There are a growing number of studies on identifying and minimizing the environmental impacts of unconventional gas development. This study aims to examines the current environmental policies and regulatory systems related to the unconventional gas development. The study shows that few environmental regulation exists concerning unconventional gas development, even in the USA where unconventional gas development is most actively pursued. Regulations, however, are being developed based on studies currently underway on health and environmental risks of unconventional gas development and on guidelines designed to reduce the risks. In a world where environmental regulations are ever strengthening, review the environmental regulatory systems and guidelines about unconventional gas need to be established for Korean firms to understand environmental impacts of unconventional gas development they invest or take part in, enabling them to manage and operate gas activities in a way that minimizes environmental damages.

To evaluate impacts of the construction noise, Trionyx sinensis, inland fishers aquacultural organism, were exposed to control groups (about 55 dB) and noise groups (80 dB). The survival, growth rate and feeding efficiency of the juvenile Trionyx sinensis were measured at 10, 20 and 30 days intervals (each 9 hours/day). No significant mortality occurred during the experiments, but growth rates (1.7 times) and feeding efficiency (1.83 times) showed significant reduction in time-dependent manner. Also, serum cortisol (6.7 times) and corticosterone levels (1.37 times) in noise groups significantly increased by the noise exposure, compared to the controls, In conclusion, this study may provide the fundamental knowledge on adverse effects Trionyx sinensis and apply to assessments on the impacts of aquaculture industry by construction noise.

Habitat loss and fragmentation are ongoing major anthropogenic impacts on landscapes, which can strongly affect ecosystems, populations and species. The studies on forest fragmentation have been progressed, but the studies on definition of forest fragmentation and their synthetic trend in South Korea still leaves much to be desired. Therefore we set the definition of forest fragmentation and reviewed the related papers. We can give a definition that forest fragmentation is not only a process of spatial landscape transformation, but also a process of ecosystem change by it. The trend of studies on forest fragmentation divided into two fields, landscape and ecosystem changes. Forest fragmentation caused by land change altered the composition and configuration of forest patches. Most studies related on that analyzed the change using landscape index. The effects of forest fragmentation on ecosystem subdivided into three fields : biodiversity, edge effects, and invasive species, but the studies in South Korea is short. The study on relations between forest fragmentation and ecosystem change is necessary to face the Convention on Biological Diversity in South Korea. In addition, the fundamental studies on biodiversity is important to mitigate against forest fragmentation.

User's impacts on trail deteriorations and edge vegetation were studied in Sokri Mountain National Park in 1990. The entire width, bare width and maximum depth of trail as the trail condition were significantly greater on the more heavily used trail. Deteriorations of trail which were surveyed at the total of 52 were significantly different from those of non-deteriorated points. The dominant trees in the crown layer of trail edge are as follows. According as the altitude rises, the changes happen from Quercus serrata to Quercus variabilis, Pinus densiflora, and to Quercus mongolica at Joongsajaam course, and from Pinus densiflora, Quercus variabilis to Quercus mongolica at Birosanjang course. And Stephanandra incisa, Symplocos chinesis for. pilosa show high relative dominant value at Joongsajaam course, Lindera obtusiloba, Fraxinus sieboldiana show one at Birosanjang course.
