Based on the hedonic pricing method, this paper investigates the effect of air quality on the apartment price in Seoul. The empirical results show that both the structural variables such as years of construction, heating system, and size of apartment complex and accessability variables such as distances to subway station and parks provide statistically significant effects on the price of apartment, Especially, the dendity of sulfurous acid gas ($SO_2$) and ozone ($O_3$) in the air, indicating air quality, negatively affect the price of apartment, This implies that as the condition of air quality to become worse, apartment price decreases, Therefore, when the degree of aversion of apartment residents against the air pollution affects the formation of apartment's market price, the MWPT(Marginal Willingness to Pay) in order to improve the air quality 10% has been estimated as 36,000~39,000Won per month.

최근 클라우드 컴퓨팅이 빠르게 확산되면서 기존의 인터넷 환경 뿐 아니라 모바일 클라우드 컴퓨팅에 관한 관심이 급증하고 있다. 스마트폰을 비롯한 모바일 단말기는 하드웨어를 비롯하여 애플리케이션, 서비스까지 모든 면에서 빠르게 변화하고 있다. 하지만 웹표준 준수 및 모바일 웹에 대한 이해가 부족한 국내 모바일 인터넷 환경에서는 인터넷 접속이 원활하지 않고, 국내 웹사이트의 대부분이 다양한 기능과 화려한 디자인에 주력하여 개발하고 있기 때문에 스마트폰이나 태블릿 PC에서 접속시 사용성 및 접근성을 떨어뜨리는 요인이 된다. 이에 본 연구는 모바일 클라우드 환경에서 사용성과 접근성을 고려한 웹 인터페이스를 제안하고 이를 사용성 평가를 통하여 검증하고자 한다. 우리는 이미 선행 연구를 통하여 모바일 단말기 환경에 최적화된 메인페이지 인터페이스를 제안하고 그 사용성이 개선되었음을 입증하였으나, 이는 웹사이트 전체에 대한 사용성을 보증하지 못한다. 본 연구는 선행 연구를 통하여 제시하였던 웹표준의 준수와 그를 통한 웹 인터페이스 방식이 해당 웹사이트 전체에 걸쳐 사용성을 개선함을 보인다. 우리는 클라우드 컴퓨팅에 최적화된 웹사이트를 선정하여 웹사이트 전체에 대한 사용성 평가를 실시함으로써 실제로 그 접근성 및 사용성이 개선되었음을 검증한다. 또한, 이러한 개선을 통하여 기업이나 개인 모바일 웹사이트 개발자들에게 유저 인터페이스(UI) 디자인 적용을 위한 지침을 제공한다.

Cloud computing is provided on demand service via the internet, allowing users to pay for the service they actually use. Categorized as one kind of cloud computing, SaaS is computing resource and software sharing model with can be accessed via the internet. Based on virtualization technology, SaaS is expected to improve the efficiency and quality of the IT service level and performance in company. Therefore this research limited cloud services to SaaS especially focused on collaborative application service, and attempts to identify the factors which impact the performance of collaboration and intention to use. This study adopts technological factors of cloud SaaS services and factors of task characteristics to explore the determinants of collaborative performance and intention to use. An experimental study using student subjects with Google Apps provided empirical validation for our proposed model. Based on 337 data collected from respondents, the major findings are following. First, the characteristics of cloud computing services such as collaboration support, service reliability, and ease of use have positive effects on perceived usefulness of collaborative application while accessability, service reliability, and ease to use have positive effects on intention to use. Second, task interdependence has a positive effects on collaborative performance while task ambiguity factor has not. Third, perceived usefulness of collaborative application have positive effects on intention to use.

As Incheon International Airport(IIA) is located in an island 50-km away from Seoul, various travel equipments for access are required. So far two connecting bridges are constructed funded by civilian funds. For the further bridge construction, the reduction of forecast traffic amount and the government subsidy for the civilian funds are big issues. Comparing the access traffics of IIA to those other competing airports, traffic conditions inside the airport are superior to other competing airports from the management point of view, as utilization conditions and equipment capacities are periodically monitored and evaluated to set up comprehensive countermeasures following constructing by stages. However, while the accessability to IIA is very important, as IIA is built on an island the conflicts between near-by developers and traffic facility operators make further bridge construction difficult. As improving the accessibility to an airport is not easy to achieve only by the IIA management's efforts, the central government level authorities should organize a committee with agencies concerned and analyze the characteristics of access traffic periodically to suggest reform measures for each organization concerned to implement appropriate undertakings at apt timing. For the future, central government's level empirical research on the airport accessibility for synthetic and systematic plan set-up is expected.
