Traditional software testing typically uses many physical resources to manually build various test environments, resulting in high resource costs and long test time due to limited resources, especially for small enterprises. Cloud computing can provide sufficient low-cost virtual resources to alleviate these problems through the virtualization of physical resources. However, the provision of various test environments and services for implementing software testing rapidly and conveniently based on cloud computing is challenging. This paper proposes a multilayer cloud testing model based on cloud computing and implements a hybrid cloud testing system based on virtual machines (VMs) and networks. This system realizes the automatic and rapid creation of test environments and the remote use of test tools and test services. We conduct experiments on this system and evaluate its applicability in terms of the VM provision time, VM performance and virtual network performance. The experimental results demonstrate that the performance of the VMs and virtual networks is satisfactory and that this system can improve the test efficiency and reduce test costs through rapid virtual resource provision and convenient test services.

Many of hotel customers obtain information from hotel websites to find the best alternative. One of the crucial information for the choice is spatial/visual information of hotel rooms. However, hotel website provides photographs only showing representative room features that may not be sufficient to give a full understanding of hotel room to customers. HMD-based 3D virtual environments (HVE) created by 3D camera could improve customers' experiences of hotel rooms by providing full virtual tours of hotel rooms. However, to the best of our knowledge, whether HVE can adequately provide similar customers' perception on spatial/visual information remains unproven as physical hotel rooms. The present study thus aims to verify how similar and reliable information on physical hotel room HVE provides to hotel customers in comparison with hotel website with 2D photograph and display-based 3D virtual environment. For this purpose, this study conducted a comparative experiment to investigate perception of three environments. As a result, the study found that HVE is more effective to provide spatial/visual information as similar as an actual hotel room. In addition, HVE increases customers' perceptions towards the reliability of information, the quality of hotel room and intention to book.

New computing paradigm in ubiquitous computing environments is revolutionizing the way people interact with computers, services and the surrounding physical spaces. In order to provide stronger authentication, MIST proposed an authentication framework for ubiquitous computing environments and assigned confidence values to some authentication methods to facility the combining. However, the assigned confidence values lack sufficient evidence. In this paper reliable confidence values for each authentication method used in MIST is proposed. These confidence values can combine multiple confidence values in some manner, producing a more accurate net confidence value. Authentication entities with confidence values allows the authentication framework to blond nicely into ubiquitous computing environments.

Nowadays, domestic hospital business is under the great threat from the environmental changes caused by the entrance of foreign hospitals and the technical changes related to information systems. In such a situation, to enhance the competitive edge of a hospital, it is needed to set up a competitive strategy and to construct an efficient information systems to back up the competitive strategy. If the hospital information systems(HIS) is consistent with a competitive strategy backing up, the competitive force of a hospital will be enhanced. For this respect, the influence of the competitive strategy and HIS construction environments on the performance of HIS was examined. The results suggested that if a HIS should be newly constructed or should be restructured, it is necessary to select construction environments of HIS such as physical environments, development methods and development tools to support functional strategy effectively based on the competitive strategy adopted by a hospital.

본 연구는 근로환경이 근로자의 객관적 주관적 보상과 어떠한 관계를 가지는지를 분석함으로써 한국노동시장에 나쁜 근로환경에 대한 보상이 존재하는지를 확인하고 시사점을 제공한다. 근로자가 당면하고 있는 다양한 근로환경과 보상지표를 제공하는 한국근로환경조사(KWCS) 자료를 사용하여 분석한 결과 나쁜 근로환경을 대표하는 위험성은 임금과 유의미한 관계를 보이지 않는 반면 보상만족도와는 부(-)의 관계로 나타난다. 이는 근로자들은 나쁜 근로환경에 대한 보상이 이루어져야 한다고 인식하고 있으나 실제 노동시장에서는 금전적 보상이 이루어지지 않는다는 것을 시사한다. 또한, 노동시장에서 물리적인 위험요인보다 정신적인 위험요인에 대한 기대 보상수준이 높게 나타나며, 이러한 경향은 남성에 비해 여성이 더 크게 나타난다.

Background: Social status might be a determinant of occupational health inequalities. This study analyzed the effects of social status on both work environments and health outcomes. Methods: The study sample consisted of 27,598 wage employees aged 15 years and older from among the Korean Working Condition Survey participants in 2011. Work environments included atypical work, physical risks, ergonomic risks, work demands, work autonomy, social supports, and job rewards. Health outcomes comprised general health, health and safety at risk because of work, the World Health Organization-5 Well-being Index, work-related musculoskeletal disease, and work-related injury. Multivariable logistic-regression models were used to identify the associations between social status and work environments and health outcomes. Results: Employees in the demographically vulnerable group had lower occupational status compared with their counterparts. Low social status was largely related to adverse work environments. Especially, precarious employment and manual labor occupation were associated with both adverse work environments and poor health outcomes. Conclusion: Precarious and manual workers should take precedence in occupational health equity policies and interventions. Their cumulative vulnerability, which is connected to demographics, occupational status, adverse work environments, or poor health outcomes, can be improved through a multilevel approach such as labor market, organizations, and individual goals.

The purpose of this study was to investigate the effects of physical environments change on children. Specifically, this study investigated the effects of a newly designed elementary school environment to implement open education on elementary school students. The changed environment was improved in various aspects including architectural type, the number of space types, layout, shape of the building, and color planning. This study showed evidence of interaction between aspects of the physical environment and the actual behaviors of children. The impacts of change in physical environment, more specifically, on children was confirmed by the study. Therefore, this study can be used as a basis to insist why physical educational environment needs improvement, to insist importance of physical educational environment and to justify importance of physical environment in educational setting.

Marine organisms in Antarctica live in an environment which exhibits variability in physical processes over a wide range of temporal scales, from seconds to millennia. This time scale tends to be correlated with the spatial scale over which a given process operates, though this relationship is influenced by biology. The way organisms respond to variability in the physical environment depends on the time-scale of that variability in relation to life-span. Short-term variations are perceived largely as noise and probably have little direct impact on ecology. Of much greater importance to organisms in Antarctica are seasonal and decadal variations. Although seasonality has long been recognised as a key feature of polar environments, the realization that decadal scale variability is important is relatively recent. Long-term change has always been a feature of polar environments and may be a key factor in the evolution of the communities we see today.

A person's residence is the primary environment which affects physical and emotional-gratification. Residential environments are very important to a person's quality of life. Because the age of society has rapidly increased, we must take a profound interest in the welfare and residences of the aged. While the government has begun to prepare for an aging society, the residential environments of the aged has not been fully considered. Because the welfare of the aged begins in the house, the term 'residence for the aged' is not limited to the physical space. Because residences for the old aged are included in various social policies such as family relations, social security, health care, safety etc, relevant policies for these residences must be prepared as rapidly as possible. This study-focused on both the importance of residences for the aged and the residential desires of the aged, and aims to propose planning criteria for the residences of the aged.
