Payment of Forest Landscape Service (PFLS) is based on the value of landscape conservation and is a positive forest policy inducing the owners of mountains to improve environmental service quality with economic incentives. The purpose of this study is to test the feasibility of PFLS and find out the elements related to PFLS such as associated statutes, target applications, eligible owner's requirements, and applicable environmental services. Research sites were selected in designated reserved forests by law and surveys were carried out with 28 professional forestry engineers and 10 owners of reserved forests located in Chungnam Province in November, 2008. As a result, the owners are willing to participate pilot-project of PFLS if they could have tax incentives. Preferred activities in their forestry are eco-tourism and carbon emission trading as PFLS business model. Although they expect low economic benefit from the PFLS, respondents answered introducing PFLS will give good opportunities for owners of a reserved forest to enhance willingness to manage their forestry properly for the landscape conservation. In this study, PFLS evaluation indicators and policy directions are established and recommends the strategies to cope with changing needs of forestry conservation by inducing the owners' active participation in the sustainable forest landscape management.

This study investigates the stigma effect of unwelcomed facilities on apartment prices through multiple regressions based on hedonic price method. The areas studied are Sang-gye Jugong 7, 9, 10 apartment complexes. The facilities analyzed are the Chang-dong Electric Subway Depot and the Do-bong Driver's License Agency. The factors studied include the environmental variable (the elapsed time since the announcement of the re-location of these facilities), the view commanding, the distance from Chang-dong Depot, the distance from Do-bong Driver's License Test Course, the distance from neighboring facilities (subway stations, schools, parks and so on), the floor and each dwelling's exclusive space. The data used are 2,822 sales which have been collected since January 1, 2006. The facts found are as follows; first, the view commanding and the distance from the unwelcomed facilities are statistically significant. second, the environmental variable, 'days' turns out to have a positive (+) and a negative (-) significant relationship with the dependent variable, 'price', in period II and period IV respectively. This implies that the stigma effect is real. third, there are significant differences in the influence on the apartment prices among the independent variables according to time. fourth, the stigma effect is estimated as 33,686,920 Korean won in the case of the apartments which have the view commanding and 30,311,844 won in the other case before the global economic crisis. This effect seems to decrease to 22,085,078 won after the crisis. These facts suggest that stigma effects could be considered as one of the benefits in the cost-benefit analysis of Chang-dong Depot re-location project to produce somewhat higher NPV or B/C ratio.

This study was conducted to encourage dissatisfied consumers to initiate an active complaining process over beauty salon services as well as to reduce consumer dissatisfaction at the time of using such services. A questionnaire survey was conducted with female consumers over the period between December 1 and December 20, 2004. A total of 753 questionnaires were used for the final analysis. The following findings were obtained: 1. Consumer dissatisfaction index with beauty salon services was 23.02 (65.77/100) and the respondents showed the highest level of dissatisfaction with the price. 2. The level of complaints about beauty salon services was very low, as shown by the index value 7.12 (25.43/100). Most of the respondents simply did not go back to the particular beauty shop, or complained privately to people around them when they felt dissatisfied with beauty service. 3. Benefit awareness and level of dissatisfaction had the greatest effect on the complaint behavior about unsatisfaction beauty salon services.

The procedures of Continuous Descent Approach(CDA) is designed to minimize the thrust required during landing, thereby reducing fuel consumption, noise and emissions compared to conventional approach procedures. Widespread implementation of CDA would result in significant reductions in the environmental impact and aircraft operation costs. This paper estimated the possible economic effects from the perspective of airliners through cost-benefit analysis, provided that the CDA is introduced. It is now proposed that a more comprehensive analysis model, which includes the reduced ATC communication burden between controllers and pilots, not to mention the economic aspect, should be established for the improvement.

Diatoms have become an integral part of the UK's freshwater monitoring strategy over the past two decades, mostly in response to increasingly stringent European Union (EU) legislation. The use of diatoms is based on strong correlations between diatom assemblages and environmental variables, and from knowledge of the "expected" (= "reference") state of each river. The nationwide overview of the ecological health of rivers this gives allows those stretches of rivers which fail to meet EU criteria to be identified. This, in turn, allows appropriate remediation measures to be planned. Because diatom assemblages vary in space and time, even within a single water body, effective use of diatoms requires a consistent approach in order to minimise uncertainty. This includes the use of methods which comply with European Standards, a training and accreditation scheme for analysts, and a suite of quality assurance methods. Those aspects of uncertainty that cannot be readily controlled have been quantified and all estimates of ecological status are accompanied by the appropriate "confidence of class" and "risk of misclassification". This, in turn, helps planners prioritise those locations which are most likely to benefit from remediation.

Feed conversion efficiency contributes directly or indirectly on the cost benefit ratio of silkworm rearing and is considered to be an important physiological criterion for evaluating the superiority of silkworm breeds/hybrids. Food intake, assimilation and conversion of indigenous as well as exotic silkworm races are well studied by many researchers. In this review, an attempt has been made to consolidate works on feed conversion aspects of indigenous and exotic silkworm races. The paper also deals with the effect of various factors viz., nutritional, environmental and feeding on food assimilation and conversion parameters of mulberry silkworm.

Issuance of certification and licensing for toxicologists authorized by the Japanese Society of Thxicology (JST) became effective on July 24, 1997. The certification system consists of examination, eligibility requirements for the applicants, authorization/license by the board of trustees of JST, and the re-certification of previously authorized qualification. In the last 2-3 years, about 30-40% of candidates for the examination have succeeded. The Committee has estimated that the level of the examination would be sufficient to determine qualified toxicologists. This updated status and a detailed explanation are to be presented at the workshop. In global terms, the JST special committee agrees that "harmonization of certification/registration procedure for qualified toxicologists means to ensure/set the minimum requirement for the global authorization of qualified toxicologists". The following items in global authorization are ad-dressed for further discussion: (1) What's the benefit\ulcorner (2) Toxicological safety assessment standards, and (3) the JST position for authorization.orization.

This project has been designed for people to experience and understand the process, importance and benefit of coal fire plants. As the biggest and first typical Korean fire plant using coal, Boryeong fire plant has had important roll for the Korean industries. Even so, people has had wrong prejudice for the fire plant in terms of environmental protection. To do these kind of rolls, this museum has been designed with theme, "Boryeong fire plant mating symbiotic relationship between nature, human and technologies." The space was zoned with five major themes: i. circulation of energy in nature, ii. electric power and eco-fire plant, iii. future energy, iv roll for future of environment, v. Korea as the leading energy industry. The design has been developed focused on spatial experiences to make 'Design Sequence' with linear circulations haying several important destinations. The interior has been finished with minimal color and materials projected by big sized movie and various LED movie system. Concept of appordance has been used to make interactive experiences between exhibits and visitors.
