본 현재 우리나라 온실가스 배출은 2020년까지 BAU 대비 30% 감축을 목표로 하고 있으며, 이를 위해 정부는 다양한 온실가스 감축 정책을 추진 중에 있다. 특히 공공건축물에서의 온실가스 감축 효과는 현재 활발한 논의가 이루어지고 있다. 공공건축물은 시민들의 세금으로 운영되고 관리된다는 점에서 에너지효율 개선을 통한 온실가스 감축이 반드시 요구되기 때문이다. 이러한 배경에 따라, 본 연구는 공공건축물을 실질적으로 이용하는 주민이 어느 정도 수준에서 비시장 재화에 대해 환경적 가치 판단을 갖고 있는지 알아보는 데 목적이 있다. 연구 결과, 초기제시금액 중 금액이 높아질수록 응답자의 지불의 사가 낮아지는 것으로 나타났다. 이는 지불여부에 따른 2차 제시금액도 마찬가지의 결과를 보였다. 또한 이중양분선택형 CVM의 분석에 따르면 소득 수준은 비용지불의사에 양(+)의 영향을 주는 것으로 나타났으나 이외에 변수들은 별다른 영향을 주지 않는 것으로 나타났다. 따라서 향후 녹색 공공건축물 조성에 있어 더 효과적인 온실가스 감축 정책을 추진하기 위해서는 지역주민의 참여가 반드시 필요한 것으로 보인다.

Korean food is being recognized for its excellence. This paper attempts to provide material for the popularization of Korean cuisine with respect to foreign nationals living in Korea who are vegetarian by studying their Korean cuisine knowledge and preferences. The results of an Importance-Performance Analysis showed that though the importance values of traditional spice use such as garlic and the consideration of ingredient price were high, their performance values were low. Thus, these were areas identified as needing major improvement. Repeated measured data analysis was performed to determine variations in the perception of major factors for the development of Korean cuisine. The results indicated that simplification of seasoning was the most important factor followed by diversification of food ingredients, resale of vegetables in small quantities, ease of obtaining Korean cuisine recipes, and popularization of herbal and temple food, in that order. The least important factor in developing Korean cuisine was determined to be the reduction in levels of salt. Conjoint analysis was performed on the choices affection the selection of Korean cuisine, and price was found to be the most important factor. It was also determined that the effectiveness in the combination of fusion style, health oriented, concurrently served, medium to low price Korean cuisine was highest in preference. The next highest preferred combination was traditional style, health oriented, concurrently served, medium to low price Korean cuisine. The most significant factor to keep in mind in developing Korean dishes for foreign vegetarians was determined to be price. Furthermore, it was important to not simply reduce caloric intake but to use healthy ingredients and cooking methods.

CER 유통가격은 시장의 거래가격을 모니터링 함으로써 파악할 수 있으나 CER 발행가격을 알기 위해서는 개별 청정개발체제(CDM) 사업에 대한 투자비용을 통해 직접 추정하는 방법밖에는 없다. CER 적정 발행가격을 추정하기 위해서는 실물옵션(Real Option)의 개념을 도입해야 한다. 배출권가격의 불확실성을 고려한 CDM 사업 투자의 최적 시점은 투자를 촉발하는 배출권가격의 수준으로 정의된다. 본 연구는 경제성을 고려한 CER 적정 발행가격의 수준을 분석하는 것과 발행가격을 추정하는 과정에서 도출된 가격, 물량 자료를 통해 CER 공급곡선을 추정하는 데 목적이 있다. 우선 분석모형에 배출권가격의 불확실성을 반영하여 적정 CER 가격 수준을 도출한다. CER의 적정 가격은 CDM 사업이 가능한 손익분기점 수준과, CDM 사업 투자를 1년 지연시켰을 때의 옵션가치를 고려할 경우의 손익분기점 수준으로 나누어 분석한다. 다음으로는 CDM 사업이 가능한 손익분기점을 만족하는 CER 발행가격을 가지고 공급곡선을 추정하고, 이 공급곡선 추정 식에 발행가격 수준을 대입하는 시뮬레이션 추정을 통해 공급의 가격탄력성을 계측한다.

The bearer of the power sector's ETS compliance cost is power consumer for the following reasons. Firstly, power companies are constrained in establishing appropriate strategies to comply with ETS regulations due to the structural differences between the domestic power market and emission trading system. In other words, because power companies do not have a right to determine price and production of electricity, they have to compete with other companies under disadvantaged conditions in the emission trading market. Secondly, because ETS compliance cost is part of power production costs as it is also clearly written in the national greenhouse gas reduction road-map and the second energy supply plan, the cost should be included in power price following the power market operation rule. Thirdly, the most effective method to reduce carbon emissions in power sector is to reduce power demand, which is efficiently achieved through raising power price to a realistic level. Low power price in Korea is the major cause of rising power demand which is also the major cause of rising GHG emission. Therefore, power sector's ETS compliance cost should be included in power price to encourage power consumers' actions on reducing power consumption. Fourthly, when externality cost occurs in the process of delivering public services, usually beneficiary pay principle is applied to identify the cost bearer. Since electricity is one representative public good, the bearer of power sector's ETS compliance cost is power consumer.

This study reviews the scientific management theories and discusses those theories within the food service industry. By providing the principles and the practical implications of the theories on the food service industry, this study tries to identify their philosophies and usefulness to the industry so that the managers in the industry use them in their dylmanic operations. In the fastly changing modern globalized world, we now face a situation where it's becoming more and more difficult to mange a restaurant business. In order to build a food industry business that can maintain a continuous development in today's business environment, one will have to apply the professional management theory in a cost-reduce strategy. It is more important though to have managers, organization members, in short, any person who can work to be motivated in accomplishing these two major issues-income increase and cost reduction. In this erawhere it's getting so difficult for researches on possible strategies for these business managers to overcome their difficulties. It is for certain that in the upcoming second millenium the travel and tourism industry will be one of the world's biggest industry worldwide. Korea's hotel industry has developed since the 1988 Seoul Olympic Games and has shown great amount of competition within the same business. Thus managers have become acquainted with the "know-how" strategy and the practical and scientific managemnet theories were introduced. This helped not only to increase income but also to maximize profit. However, rather than concentration on the "Hard-ware" aspect "Soft-ware" related professional management strategies were developed along with professionalism and human service were emphazied. As such, the actual cost of food and beverages are for the hotel industry business managers the biggest shortterm expense item. Due to the natural state of food items, there is a great chance of "Loss" in preservance, and this is the reason it is complicated to effectively maintain food. As a consequence, very often, the failure to managea hotel or restaurant depends on the capability of the food and beverage preservance mangement: on how they are able to manage effectively the original price of food and beverage. Finally, the main problem of the original price management of food and beverage in Korean hotels are: a) No fixation of set price b) The difficulty to calculate the price difference between a set price and an original price. c) Lack of professinalism in managing the food and beverage original price. d) Lack of perception of the highest ranking management personnels. So as to reform these matters it is necessary to : a) Reform on the management accounting system b) Emphasize to the people in charge on the idea of original price management c) Reinforce original price mangement prevention and assurance of indepedent inspection rights d) Reat manpower
