Cloud Service Providers (CSPs) enable their users to access Cloud computing and storage services from anywhere in quick and flexible manners through the Internet. With the basis of 'pay-as-you-go' model, it makes the interactions between CSPs and the users play a vital role in shaping the Cloud computing market. A pool of virtualized and dynamically scalable Cloud services that delivered on demand to the users is associated with guaranteed performance and cost-provisioning. It needed a costing scheme for determining suitable charges in order to secure lease pricing of the Cloud services. However, it is hard to meet the satisfied prices for both CSPs and users due to their conflicting needs. Furthermore, there is lack of Service Level Agreements (SLAs) that allowing the users to take part into price negotiating process. The users may lose their interest to use Cloud services while reducing CSPs profit. Therefore, this paper proposes a generic costing scheme for Cloud services using General Equilibrium Theory (GET). GET helps to formulate the price function for various services' factors to match with various demands from the users. It is initially determined by identifying the market circumstances that a general equilibrium will be hold and reached. Specifically, there are two procedures of agreement made in response to (i) established equilibrium supply and demand, and (ii) service price formed and constructed in a price range. The SLAs in our costing scheme is integrated to satisfy both CSPs and users' needs while minimizing their conflicts. The price ranging strategy is deliberated to provide prices' options to the users with respect their budget limit. Meanwhile, the CSPs can adaptively charge based on users' preferences without losing their profit. The costing scheme is testable and analyzed in multi-tenant computing environments. The results from our simulation experiments demonstrate that the proposed costing scheme provides better users' satisfaction while fostering fairness pricing in the Cloud market.

The concept of sharing economy has received rich attention in recent years. As a typical type of business model in the sharing economy, online short rent has been paid attention by both industry and academia. In this study, we find trust to be a critical determinant to the success of online short rent platforms. Based on three dimensions of trust theory, i.e., ability, benevolence and integrity, we investigate the factors influencing tenant' willingness to participate in online short rent. We further examine the extent to which trust can influence the number of sales and comments of rooms listed at online short-term rent platforms, which can represent tenant' willingness to participate in the sharing economy. The results show that the trust dimensions represented by a landlord's personal characteristics have significant positive correlations with the number of sales and comments. For example, the real name authentication and the sesame score can represent the trust integrity; online replay ratio and the average confirmation time representing the trust sincerity, and the order acceptance ratio representing the trust ability. On this basis, we proposed some recommendations for both platforms and landlords. For example, the landlords can improve the tenants' trust by authenticating his/her real name, replying actively and timely. For platforms, when they make housing list ranking rules, they can take the landlord's personal attributes that may affect trust into consideration. Moreover, platforms can also allow landlords to supply value-added services to improve service quality and ultimately promote the virtuous circle of the platform ecosphere. Through conducting the empirical research on a particular application of the sharing economy, we aim to fill the research gap of this field in China and provide theoretical and practical contributions to the future development of online short rent.

광양항 해양산업클러스터는 현재 실질적으로 운영되는 국내 유일의 해양산업클러스터이나, 개장 이후 다양한 활성화 정책을 추진함에도 불구하고 현재까지 입주율은 낮은 실정이다. 이에 따라 입주기업 활성화를 저해하는 현행 제도의 제약요인을 식별하고 활성화 방안을 마련하는 것이 본 연구의 목적이다. 이를 위해 우선적으로 광양항 해양산업클러스터의 핵심산업인 해운항만물류분야 연구개발(R&D)사업 현황을 분석하고, 광양항 해양산업클러스터 입주가 예상되는 기업을 대상으로 설문조사를 수행하였다. 그 결과 항만·해운분야 R&D 비중이 타 분야 대비 낮고, 국내 연구개발 사업은 민간 중소기업을 중심으로 추진되고 있다. 또한 실증을 위한 항만시설 필요성이 높지 않으며, 광양항에 대한 기업 접근성 부족이 제약요인으로 도출되었다. 이를 바탕으로 본 연구에서는 입주기업 확대를 위한 개선방안을 다음과 같이 4가지로 제시하였다. 첫째, 현재 광양항 해양산업클러스터에 입주가능한 핵심산업을 해운·항만·물류분야에서 해양수산업 전체로 확대하여 해당 산업에서 R&D를 수행하는 기업이 입주할 수 있도록 개선이 필요하다. 두 번째, 현재 기업 입주 자격으로 제시되고 있는 업종코드 변경을 통해 실제 연구개발사업을 수행하는 기업이 등록된 업종을 반영함과 동시에 해양수산업 전체로 확대되는 핵심산업군을 모두 포함할 수 있어야 한다. 따라서 본 연구에서 향후 광양항 해양산업클러스터 입주기업 모집 시 활용할 수 있는 확대된 기업코드를 제시하였다. 세 번째, 현제 광양항 해양산업클러스터는 연 1~2회 입주기업을 모집하는 방식을 취하고 있으나, R&D 수행기업이 실증을 위한 항만 활용 수요가 발생한 시점에 맞추어 유연하게 입주할 수 있도록 해야 하며, 이를 위해 상시모집 체계로 전환을 제시하였다. 마지막으로 입지적으로 낮은 접근성을 극복하기 위해서는 보편적인 재정적 지원보다는 민간기업 또는 중소기업이 실질적으로 필요로 하는 연구개발에 특화된 기술개발 지원사업이 필요하며, 이를 입주 유인책으로 활용해야 한다.

This study is about architectural design for rural housing block redevelopment for districts with existing residents considering sustainable development. The study suggests development direction focusing on preserving the regional characteristics, and presentation of suburban-style housing complex reflecting on the future tenant's individuality and demand. The preexisting development approach for suburban-style housing complex which was planned by the developer, failed to recognize taste of the future tenants. Profitability being the priority, it also resulted in a serious environmental disruption. In this development however, through a systematic direction for site development and site analysis, conducting surveys through future tenants, attempted for a continuous growth of the community. The study is presented covering the following areas; site's pathway system, nature conservation plan, lot plan, land use, arrangement plan, housing plan and community facility.

This paper aims to explore the institutional difference between Tsinghua University Science Park (TusPark) in Beijing, and business incubator of Research Institute of Tsinghua University in Shenzhen (RITS), and to examine how the difference leads to different new product performance for tenants. In doing so, we use survey methodology to investigate the innovation sources, university linkages, and innovation outputs of tenants in TusPark and RITS. We found that tenants in RITS reply more on "market-driven" knowledge sources for innovation: including knowledge from customers, suppliers, and competitors. The empirical findings suggest that the technology support provided by RITS and the high dependency on "market-driven" knowledge sources jointly contribute to the better new product performance for tenants in RITS.

This paper examines the achievements and limitations of housing assistance programs for low-income households. Korean public rental housing has been rapidly developing since 2000, and thereby achieved an increase in public rental housing stock, housing quality improvements, and the reduction of rent over-burden for low-income tenants. Despite some conflicting evidence, it appears that the provision of newly-built public rental housing has helped stabilize the prices of neighboring private rental housing units. But, as we are entering an era of one million long-term public rental housing units, we need to shift our focus from quantity-oriented provision to housing maintenance for tenants, and from cost-based rental housing to affordable rental housing and better access to rental housing for low-income tenants who are not beneficiaries of government assistance. Most of all, it is very important for local governments and the private sector to actively participate in the provision of public rental housing in order to ensure a stable rental housing market.
