This study utilizes the meta-analysis for the benefits transfer (MA-BT) approach to measure social costs the 7 target sites in the City and County of Honolulu. The estimated MA models (MA-1 and MA-1) were evaluated in terms of validity and reliability criteria. This study utilized a parametric t-test and a non-parametric sign rank test for checking validity. A transfer error measured by an absolute percentage difference was utilized to check reliability their similarity. The GIS was utilized for data collection in order to measure social costs for each target site. The results clearly demonstrated that social costs were substantially higher thant direct costs and varied market conditions and different methods used. In terms of validity and reliability criteria, MA models were preferred to the mean transfer value approach. MA-BT approach is desirable for measuring social costs for a project designed to measure social costs for these 7 proposed landfill sites with inaccessible data, on short time frames, and with little money. If researchers and planners have enough time and money, they can implement primary research. If not, the meta-analysis for the benefits transfer approach can be much better than no framework. The use of a GIS can help to identify secondary data within a specific radius of each target site.

This paper analyzes the effects of nuclear power generation on industrial growth in using the data of 22 manufacturing sectors in 14 nuclear power countries. The hypothesis that the change in the proportion of nuclear power generation in total electricity generation affects industrial value-added and industrial output through industrial electricity price reduction was tested using the dynamic panel data model. First, it was estimated that the increase in nuclear power generation by a 1% leads to a 0.8% reduction in electricity price. The results indicate that when nuclear power generation increased by a 1% point, industrial value-added and output increased by 0.16% and 0.23%,respectively, in the short-run and by 0.51% and 0.85%, respectively, in the long-run. It was also inferred that the effect of nuclear generation on industrial competitiveness working through electricity price reduction rely on institutional settings in the electricity markets. That is, the competitive effect is greater in the countries such as U.K and Japan where electricity price is high and price volatility is large. Meanwhile, in Germany which has pursued phasing out nuclear power, industrial competitiveness is promoted through stable electricity supply.

Despite the impacts of the climate changes on the pelagic ecosystem, few studies have examined the pelagic-benthic coupling in the adjacent East China Sea and Korea Strait. Therefore, the species composition and abundance of the macrobenthic community, as well as the potential food sources of benthic fauna were investigated in the present study using stable isotope analysis (${\delta}^{13}C\;and\;{\delta}^{15}N$) for suspended particulate organic matter (SPOM), sedimentary organic matter (SOM), phytoplankton, and zooplankton. A total of 157 macrobenthic fauna were collected, and the density of the macrobenthic fauna ranged from 4 to 434 ind./0.25 $m^2$, with an average density of 149 ind./0.25 $m^2$. The density of the benthic fauna increased moving from offshore shelf sites to coastal sites adjacent to the Korea Strait. Cluster analysis showed that the macrobenthic communities consisted of three distinct groups: group A in the Korea Strait, group B in the East China Sea, and group C near Ieodo. The dominant species in group A were the amphipods Photis japonica and Ampelisca miharaensis, followed by the polychaete Scolotoma longifolia. Environmental variables, such as the temperature of the seawater and sediment, and oxygen, and chlorophyll a levels, appeared to affect the structure of the community, suggesting the importance of coupling with the pelagic system. The ${\delta}^{13}C$ values of SPOM and zooplankton ranged from -22.97 to -23.5% and -19.92 to -21.86%, respectively, showing a relatively narrow range(<1%) between the two components. The difference between the ${\delta}^{13}C$ values of SOM and pelagic organic matter was also within 1%, suggesting that the SOM originated from the pelagic system, which is an important factor controlling the macrobenthic community.

This study was conducted to examine the impacts of different soil water potentials on environmental soil properties related to the moisture injury of Korean raspberry (Rubus coreanus Miq.). Soil water potential in the plastic film house plots was differentiated from -5 to -40 kPa. Soils in the plots contained 5.6% of plant available water. Increasing soil water contents based on the changes in water potential increased soil pH and exchangeable $Ca^{2+}$ content and decreased exchangeable $K^+$ and total N contents. It also declined soil organic matter content at 9 days after water treatments. Relationship between water potential and soil water content was given as an exponential equation, y = 96.534 - 20.28In(x). In particular, when the water potential was higher than -20 kPa (27.5% of soil moisture content), it decreased chlorophyll content in the raspberry leaves, inhibited N uptake by the plant, and increased phosphorus content with increasing days after water treatment. Also, as the 7 days after water treatment at higher than -20 kPa of water potential, the root activity of the plant was significantly decreased, and trunk (top)/root (T/R) ratio of the plant markedly declined until 9 days after water supply. Carbohydrate contents in the raspberry plant leaves and roots at dormant stage were the lowest at -5 and -10 kPa of water potential plots, and it may cause winter injury to the plant.

Recently, by fast industralization and development without environmental concern, our environment deterioration have being continued rapidly. Therefore, many species is placed on crisis of extinction or was already extincted by habitat destruction. In Minjujisan area, there is a plan to construct the Sport and Leisure Complex by which convert the forest conservancy district to the district of development promotion and district of sighseeing and leisure by Yongdong District. To investigate the avifauna impacts by habitat destruction, bird censuses was carried out before the Sport and Leisure Complex be construct in Minjujisan and Sokgisan area during 4-5 May, 1992 and 16-21 June, 1992. Total 229 birds of 41 species in 23 family of 9 orders were recorded during censuses. Sitta europaea amurensis was the most abundant species and Parus ater amurensis, Phylloscopus borealis xanthodryas, Parus major wladiwostokensis, Parus palustris hellmayri, and Turdus pallidus were dominant species. Accipiter nisus nisosimilis, Accipiter soloenis, and Otus scops stictonotus were found out to the natural monuments in this suvey. Halcyon pileate was observed to a rare bird in this surveyed area. Species diversity of this census was 3.381 which showed slightly higher degree than other surveyed area. The area of Minjujisan, Sokgipong, and Samdopong which have little pollution agent around there and kept away from mankind were approved the heavy avifauna area which have so many bird species. Biogeographically, the Taebaek Mountains was connected with the Sobaek Mountains through this area, therefore it was significant that many animal species could be move to each mountains ranges. The construction plan of the Sport and Leisure Complex in Minjujisan area should be restrain with concern about environmentally destruction by the Muju Resort in Dokyusan National Park which connected to that area have master plan to development the ski slopes for the 1997 Universiad with permission by the Ministry of Environment.

This study tries to investigate the changes of mortality regarding heat waves which are usually considered as one of the most direct impacts of climate change. Based on 17 years data period (1994-2010), each city's threshold temperature and minimum mortality temperature are recognized. According to the results, minimum mortality temperature varies from 23 to $25^{\circ}C$, showing minimum temperature corresponding to $23^{\circ}C$ in Gangwondo and maximum temperature corresponding to $25.4^{\circ}C$ in Jeollabukdo and Major 7 city group. In case of threshold temperature, it ranges from 27 to $30^{\circ}C$. The cities having higher threshold temperatures tend to have large populations and vice versa. In addition, the cities having negative demographic vulnerability relatively have lower temperatures, representing correlation -0.44(p=0.06). The socio-economic-environmental vulnerability shows negative correlation with minimum mortality temperature(r=-0.36, p=0.032) and threshold temperature(r=-0.29, p=0.081). This paper represents that the number of mortality could increase rapidly and show large spatial differences in the number of mortality depending on various factors including natural, social, and economic factors of each region.

Firms that have adopted internet technology have been confused by distorted market signals. It is natural to look at marketplace outcomes for guidance, when confronted with a new business phenomenon. However, market signals can be unreliable in the early states of any important new information technology. New technologies trigger rampant experimentation, and the experimentation is often unsustainable. As a result, market behavior is distorted and must be interpreted cautiously. In Chapter 1, we review a concept of business model and roles of strategies in a business model. In Chapter 2, we discuss a strategic auditing method for analyzing market/channel positioning, product/service positioning, value chain/value network positioning and external environmental factors. In chapter 3, we introduces major frameworks for understanding factors forming strategies. The strategic grid model categorizes four quadrants depending on the level of impacts of information technology on operation and strategy. The strategic alignment model presents a new method of assessing an alignment of information technology and business throughout all elements of a business model. In this research, we review the concept of a business model. This research introduces factors that shape strategies and new frameworks for understanding these factors. The research objective of this manuscript is to present a guidance for firms how to use information technology for attaining sustainable competitive advantages.

Forestry as with all land matters, under the Constitution, is a State matter. Thus the States, numbering 14, have considerable autonomy in decisions on forestry and related matters. However, the Federal Government, having jurisdiction over such issues as defence, education and research, endeavours to coordinate, standardise and advise the States on matters where the States have jurisdiction. However, forestry being a major revenue earner, is jealously guarded by the States. Under such circumstances and recognising the interdependencies of impacts of decisions at the State level, the institutional organisations play an important role in coordinating state activities to ensure that the benefits to the country as a whole are not sacrificed in favour of interests of individual state. Various legislative mechanisms have been established to ensure this coordinated effort. A National Forestry Council forms the apex of national political coordination. The Federal Forestry Department is responsible for coordination of developmental activities at the State level, which are implemented be the State Forestry Departments within Peninsular Malaysia. Research is carried out centrally by the Forest Research Institute of Malaysia(FRIM), a statutory body formed in 1985 from a research division of the Forestry Department. The Stares of Sabah and Sarawak have their own Forestry Departments, independent of the Federal Department, and each with its own research unit independent of FRIM. Tertiary education in forestry is the sole responsibility of the Agricultural University at Serdang with a campus for Diploma level training in Sarawak. In the developmental area in the State of Sabah, institutions have been formed to focus on specific areas of activities. The Sabah Foundation is responsible for the long term development of the State forests with a concession of about one million ha. Sabah Forest Development Authority(SAFODA) was formed to carry out reforestation of denuded areas. Sabah Forest Industries Ltd.(SFI) is responsible for the country's only integrated pulp and paper industry with its own afforestation program to support its resource supply. In Peninsular Malaysia various states have established State Corporations to manage large "sustained yield" concessions. While wildlife and state parks are managed by the respective forestry departments in Sabah and Sarawak, it is the responsibility of a separate department in Peninsula Malaysia called the Department of Wildlife and National Parks(under the Ministry of Science, Technology and Environment). Timber trade legislation and promotion in the Peninsular is the responsibility of the Malaysian Timber Industries Board(MTIB) for Peninsular Malaysia and the Sarawak Timber Industries Development Corporation(STIDC) in Sarawak. In the area of NGOs ; the Institute of Foresters Malaysia, is the professional body of forestry in the country. A Malaysian Forestry Society caters for the public participation and interest. Other environmentally related NGOs such as the Malayan Nature Society, the Environmental Protection Society, World Wildlife Fund, Friends of the Earth and the Consumers Associations also involve themselves in specific forestry activities. A number of timber trade associations are also formed by the private sector to assist the industries.

Evapotranspiration (ET) from the various surfaces needs to be understood because it is a crucial hydrological factor to grasp interaction between the land surface and the atmosphere. A traditional way of estimating it, which is calculating it empirically using lysimeter and pan evaporation observations, has a limitation that the measurements represent only point values. However, these measurements cannot describe ET because it is easily affected by outer circumstances. Thus, remote sensing technology was applied to estimate spatial distribution of ET. In this study, we estimated major components of energy balance method (i.e. net radiation flux, soil heat flux, sensible heat flux, and latent heat flux) and ET as a map using Mapping Evapo-Transpiration with Internalized Calibration (METRIC) satellite-based image processing model. This model was run using Landsat imagery of Gyeongan watershed in Korea on Feb 1, 2003 and Sep 13, 2006. Basic statistical analyses were also conducted. The estimated mean daily ETs had respectively 22% and 11% of errors with pan evaporation data acquired from the Suwon Weather Station. This result represented similar distribution compared with previous studies and confirmed that the METRIC algorithm had high reliability in the watershed. In addition, ET distribution of each land use type was separately examined. As a result, it was identified that vegetation density had dominant impacts on distribution of ET. Seasonally, ET in a growing season represented significantly higher than in a dormant season due to more active transpiration. The ET maps will be useful to analyze how ET behaves along with the circumstantial conditions; land cover classification, vegetation density, elevation, topography.

In this study, fish fauna and stream characteristics were surveyed from June to October of 2014 in 31 sites of 23 small streams of Namhae Island. During the study period, 38 species belonging to 30 genera under 13 families were collected. Cyprinidae and Gobiidae fish occupied 28.9% (11 species) and Cobitidae fish accounted for 10.5% (4 species). The dominant family was Cyprinidae, and the most dominant species was Zacco koreanus with 30.3% (1,089 individuals) of the total. Eight species (33.8%) such as Zacco koreanus, Squalidus gracilis majimae, Coreoleuciscus splendidus, Pseudobagrus koreanus, Iksookimia hugowolfeld, Iksookimia longicorpa, Silurus microdorsalis and Liobagrus mediadiposalis were Korean endemic and one species of Micropterus salmoides was exotic. According to the analysis of the community based on the diversity, evenness and richness indices, fish community seems to be more stable in the S7. The small streams were classified into three types of steep mountainous, mountainous-flatland, and flat land streams, and their types were categorized by their features of stream width, water depth, bottom substrate, riparian vegetation, and land use patterns. Principal component analysis based on species abundance classified fish communities into three main groups according to human impact and land-use pattern change. These results suggest that fish community structures were primary affected by the longitudinal environmental changes and these were modified by the habitat condition in accordance with the land use pattern change in the small streams.
