In the aftermath of nation-wide controversy over "conservation vs. development" of the costal wetland in the Saemangeum, Korea could legislate the laws of wetland conservation and costal management in 1998. Since then, the public interest in the costal mudflats and its conservation has increased greatly, but the controversy on the economic value of mutflat wetland and the futher (un)necessity of reclamation) is not yet settled. In the cases of Korea dealt, economic valuation of wetland was performed mainly in the milieu of reclamation(development) vs conservation conflict, or from interest of recreational use. Korean studies used to estimate economic value of development case and conservation case respectively and then tried to compare these two value, as is sometimes done also in other countries. But the scrutiny of the results of these studies leads us to conclude that the revealed wide discrepancy among estimated values, above all other methodological problems, denies any practical applicability to the actual policy use. Benefit transfer as a convenient alternative method of valuation can not be usable either in our cases, because there is too few reliable estimated economic values of mudflat wetlands.

In this study, we developed a method to assess quantitatively the amount and the economic value of water quality regulating service of ecosystem services. Numbers of species and aquatic organisms such as fish increased because of the improved water, but it was due to complex factors such as water quality regulation services of ecosystems, installation of environmental facilities for water quality treatment, and water quality regulation. Therefore we sought ways to quantitatively estimate the value of ecosystem regulation services. In this study, we propose a method to estimate the quantitative value of water quality regulation service of ecosystem by utilizing the total amount of water pollution. In addition, the economic value evaluation method was proposed by multiplying the estimated the quantitative value of water quality regulation service of ecosystem by the unit cost per unit capacity. Finally, the ecosystem water quality regulation service was estimated by using the evaluation method for BOD and T-P in Nakdong river watershed.

This paper examines the evaluation and categorization of national heritage 'Myeongseung(scenic places)' from the viewpoint of world heritage concept and its criteria. This study focuses on Myeongseung because the author thinks it implies the unique human-nature relationships that have been evolved in Korean Peninsula, and then draws some pending problems with the evaluation of those heritage. Formerly, the paper discusses theoretically the outcome and point at issue on concept, criteria, evaluation of world heritage, and then proposes three issues on the evaluation and categorization of national heritage 'Myeongseung': first, the establishment of basic concept for evaluation of heritage; second, the building of unified criteria list to cover both natural and cultural heritage; and third, the reorganization of categories for the advanced registration and management. Especially, the author emphasizes that it is necessary rather to extend actively the world heritage concept than to regard it as a fixed framework.

최근 인터넷의 성장과 함께 인터넷을 이용한 사설망인 VPN의 필요성이 커지고 있다. 본 논문에서는 확장된 NAT 기능을 이용한 VPN 기능을 임베이드 리눅스 환경에서 구현하여 기존 VPN의 단점을 보완하고 VPN 장비의 크기를 최소화 할 수 있도록 한다. 제안된 VPN 기능은 실제 인터넷 환경에 적용하기 쉬우며 보안 프로토콜이나 암호화 알고리즘을 생략하고도 강한 보안성을 제공하고, 기존의 공개망을 최대한 활용할 수 있어 그 활용가치가 높을 것으로 생각된다. 또한, 임베이드 시스템에서 VPN을 구현함으로써 장비의 소형화, 안정성 및 경제성을 실현하여 그 활용가치가 높을 것으로 생각된다.

최근 사회 각 분야에서 빅데이터를 분석하여 새로운 가치를 찾아내려는 시도가 급속히 증가하고 있다. 그러나 빅데이터를 분석하여 소기의 성과를 얻으려면 한 기관이나 기업이 자체로 보유하고 있는 데이터 뿐 아니라 외부에 있는 가치 있는 데이터가 필수적으로 필요한 경우가 대부분이다. 현재 빅데이터 이용에서 가장 어려운 것은 대용량 데이터를 다루는 하드웨어나 분석 소프트웨어 도입이 아니라 핵심적으로 필요한 외부 빅데이터를 어떻게 확보할 것인가이다. 본 고에서는 빅데이터를 효과적으로 공유하고 활용하기 위한 방안으로 오픈 데이터 인터페이스(ODI)를 제안한다. ODI를 사용함으로써 프로그램이 직접 읽을 수 있는(machine readable) 데이터 공유가 확대되고, 데이터 매쉬업이 쉬워지며, 개인의 데이터 가공 능력을 거래할 수 있는 생태계 구현이 가능해질 것이다.

Consumer satisfaction/dissatisfaction is key determinant of brand loyalty and store patronage behavior. But the results of many customer satisfaction surveys implemented by department stores show that consumer satisfactions do not predict the actual patronage behaviors well. The main reason of these surprising results would be that the consumer satisfaction indexes do not include some important determinants of consumer satisfaction. Many customer satisfaction surveys mainly focus on the evaluation of functional benefits including product assortments, merchandise prices and locational convenience. Recent studies indicate that emotional/hedonic benefits strongly influence the consumer satisfaction, intention to repurchase and intention to revisit. Our study suggests that both functional values and hedonic values should be included in developing the index of consumer satisfactions. The purpose of our study is to investigate the relationship between shopping value and consumer satisfaction, and actual patronage behavior. Shopping values is defined as the difference between total benefits and total shopping costs. Total benefits include the dimensions of product quality, service quality, and hedonic benefits. Total costs are classified as the monetary costs and non-monetary cost. The conceptual framework developed for this empirical study is as follows.

As the aviation industry has rapidly been grown, there are more factors for customers to consider when choosing an airline. In response, airlines are trying to increase customer value by providing high-quality services and differentiated experiential value. While early customer value research centered on utilitarian value, which is the trade-off between cost and benefit in terms of utility for products and services, the importance of experiential value has recently been emphasized. However, experiential value needs to be studied in a specific context that fully represents customer preferences because what constitutes customer value changes depending on the product or service context. In addition, customer value has an important influence on customers' decision-making, so it is necessary for airlines to accurately understand what constitutes customer value. In this study, we collected customer reviews and ratings from Skytrax, a website specializing in airlines, and utilized the BERTopic technique to derive factors of customer value. The results revealed nine factors that constitute customer value in airlines, and six of them are related to customer satisfaction. This study proposes a new methodology that enables a granular understanding of customer value and provides airlines with specific directions for improving service quality.

기존의 레거시 시스템은 개발과정에 있어서 이미 많은 시간과 경험과 지식을 갖고 있기 때문에 조직의 핵심 가치를 지닌 재사용 자산으로 활용할 수 있는 의미있는 자산이다. 그러므로 레거시 시스템에서 사용해 왔던 가치있는 자산들을 웹을 기반으로 한 e-비즈니스 환경에 적용시키고, 다양한 플랫폼에서 사용하기 위한 필요성이 증대되었다. 변화하는 환경에 따라 레거시 시스템을 현대화(Modernization)하는 방법중의 하나로 현재 시스템에서 운용되고 있는 것을 OMG에서 제안한 모델기반아키텍처(MDA)를 사용하여 여러 플랫폼을 쉽게 지원하고 모델기반의 통합을 하고자 한다. MDA 환경을 기반으로 기존의 레거시 시스템을 활용하기 위하여 기존의 소프트웨어를 직접 수정 없이 재사용하거나 PSM에서 PIM 변환을 하기 위하여 래퍼(wrapper를 사용한다. 본 논문에서는 이러한 래퍼의 사용에 따른 문제점을 분석하고, 요구에 따라 모델에 대한 접근방식을 다르게 사용하여 시스템의 개선상황에 유연하게 대처할 수 있도록 래퍼를 상황에 따라 적절하게 사용하는 혼합(hybrid) 방식을 적용한 개선전략을 제안하고자 한다.
