Coastal wetlands are among the most productive biomes in the Earth. The economic values include the direct use of a coastal wetland's ecosystem services, such as food, raw materials, recreation, and tourism. Other values comprise the indirect use of a coastal wetland's ecosystem services, such as carbon sequestration, waste-water treatment, and erosion prevention. In particular, Suncheon Bay is recently attracting attention as the most successful case of the preservation and restoration. This study applies Travel Cost Method (TCM) to estimate the economic value by drawing the demand curve for trips to Suncheon Bay. The TCM is an approach used for economic valuation of non-market goods and services. Based on the results of TCM, this study shows that the economic benefit from recreational uses of the site adds up to \174.7 billion per year. It is also significant in the sense that monetary information is suggested to help local policy makers evaluate the realistic values of coastal wetlands.

Ubiquitous Computing has introduced one of the most innovative international research contributions on the design and evaluation of new generations of handheld and mobile information appliances. New devices are being invented and existing devices are being improved with smaller size and increased mobility. These changes of computing paradigm are enabling the enterprises' legacy services to be automated and value-added all the more. We suggest a service framework and algorithms of provisioning healthcare services in a ubiquitous computing environment. We construct domain ontology that is related to diabetes and minimum common sense ontology for service composition. The results of this research enable integration and interconnection of devices, applications, and functions of enterprises within the healthcare services.

The objective of this study is offering new on line business model for automotive market. In order for the research aim, we conduct direct in-depth interviews with CEO, including analysis of business patterns on eight automotive firms in Gwangju city. As a result, we suggest new business model so called, Online to offline (o2o) that combines advantages in both off-line and on-line business. Techniques that o2o automotive companies may employ include in-store pick up of items purchased online, allowing customers. Purchasing the automotive is not only a car but also services including insurance, warrant services. o2o business model suggested shows the operating of the goods and service sale. When it comes to characteristics of automotive conventional sale patterns, utilization of the online-to-offline commerce has not eliminated the advantages that e-commerce companies have. That model can enhance the new values for customers as well as new market creation. Also, this new business model (o2o) can contribute the emerging industry business model installed based in particular, emergence of Iot (Internet of thing) in terms of sharing knowledge and information between enterprise and customers.

Cloud BIM, which incorporates cloud computing technology and BIM technology, is increasingly used in construction. In particular, the recent trend of cloud services in IT field is to provide customized cloud services according to the characteristics of users. These changes are also linked to the cloud BIM, which is emerging in the construction industry. However, cloud BIM researches and commercial technologies that are currently underway do not reflect these trends, and they provide services through generalized management functions in construction projects. In order to solve these problems, a new type of customized cloud BIM service is needed that can provide cloud services by reflecting the characteristics of the project, customization based on the user's work, and providing the knowledge service. Therefore, this study aims to derive the system requirement function that should be preceded for implementing the customized cloud BIM service, and the target project is selected as the medical facility.

PKI(Public Key Infrastructure) 인증은 개인키 소지(possession)와 개인키 보호 패스워드 지식(knowledge)이라는 2 요소 인증(2 factor authentication) 능력과 안전한 공개키 암호 프로토콜을 통해 인터넷 거래의 신뢰 인프라 구축에 많은 기여를 해왔다. 하나의 인증서로 모든 PKI 사이트를 접근할 수 있는 점도 PKI 인증의 활성화에 기여하였다. 그럼에도 불구하고 인증서 인프라 구축 비용, 인증서 관리에 따른 사용자 불편함, 그리고 개인키 보호 패스워드 관리의 어려움 등에 따른 여러 가지 문제점들이 노출되어 왔다. 최근에 주목받고 있는 FIDO(Fast IDentity Online) 인증은 PKI 인증과 같이 공개키 암호 프로토콜에 기초한 강력한 인증 서비스를 제공하면서도 사용자별 인증서 발급이 불필요하고, 생체 인증 등과 결합하여 안전하고 편리한 인증 서비스 제공을 추구하고 있다. 본 논문은 PKI 인증과 FIDO 인증의 동작 방식을 구체적으로 비교하여 각각의 장단점을 분석하고, 그에 따른 각각의 응용 분야를 제시하는 데 목적이 있다.

Customization and personalization services are considered as a critical success factor to be a successful Internet store or web service provider. As a representative personalization technique, personalized recommendation techniques are studied and commercialized to suggest products or services to a customer of Internet storefronts based on demographics of the customer or based on an analysis of the past purchasing behavior of the customer. The underlining theories of recommendation techniques are statistics, data mining, artificial intelligence, and/or rule-based matching. In the rule-based approach for personalized recommendation, marketing rules for personalization are usually collected from marketing experts and are used to inference with customers data. however, it is difficult to extract marketing rules from marketing experts, and also difficult to validate and to maintain the constructed knowledge base. In this paper, we proposed a marketing rule extraction technique for personalized recommendation on Internet storefronts using market basket analysis technique, a well-known data mining technique. Using marketing basket analysis technique, marketing rules for cross sales are extracted, and are used to provide personalized advertisement selection when a customer visits in an Internet store. An experiment has been performed to evaluate the effectiveness of proposed approach comparing with preference scoring approach and random selection.

Purpose : This study aimed to make comparison before and after CPR training for health college students (departments of visual optics, occupational therapy, and health welfare administration). The questionnaire consisted of self-efficacy, knowledge, and attitudes toward CPR affect performance ability. Through this study, the researchers tried to provide basic data in developing of cardiopulmonary resuscitation training programs and training methods for health college students. Methods : This study was applied to 83 health college students (departments of visual optics, occupational therapy, and health welfare administration) in G Province. Data were collected from September 22 to October 9, 2008. Analysis was performed by using SPSS WIN 12.0 Version program. Frequency analysis, t-test, ANOVA, and Pearson's correlation coefficients were used. Statistical significance was based on p < .05. Results : 1. There was an increase with(${\rightarrow}$ in) 1.69 point before education and 3.01 after education of artificial ventilation(p < .001). There was an increase in 1.46 point before education and 3.24 after education of airway(p < .001). There was an increase in 1.54 point before education and 2.84 after education of chest compression location(p < .001). There was an increase in 1.97 point before education and 3.13 after education of chest compression(p < .001). 2. The difference between self-efficacy, knowledge, and attitude before and after CPR education, the self-efficacy increased from 2.08 point before education(p < .001 to 3.18 point after education. Knowledge increased from 2.09 point before education(p < .001) to 3.28 point after education. Attitude increased from 1.75 point before education(p < .001 to 3.05 point after education. 3. The correlation between self-efficacy, knowledge, and attitude toward CPR), was not changed before education. After education, knowledge showed quantitative correlation(r = .219, p < .05) with attitude. 4. In regression analysis with the aim of examining influence of self-efficacy, knowledge, and attitude upon performance ability, the effect wasn't given to performance ability before education. After education, the self-efficacy was indicated to have significant effect on performance ability(p < .05).
