This paper presents a virtual sensor system that is an effective method to test application software of smart sensors. The common way of testing sensor application is to build a test board, connect sensors to the board, and test sensor applications on the board with sensor's measurements as inputs. The problem of testing sensor application software with sensor's measurements as inputs is the restriction of test data. In other words, software testers cannot manipulate test data, because test data is generated by sensors. To solve this problem a virtual sensor system is presented in this paper. The virtual sensor system enables software testers to manipulate measurements of sensors. In the virtual sensor system, generation of virtual sensors comprises three stages - sensor selection, sensor characterization, and determination of output patterns. Sensor's measurements that can be manipulated through the virtual sensor system make the process of testing efficient. To show the usefulness of our virtual sensor system, it is applied to sensor applications in Android platform and the result of experiments is shown.

Background The Sunnybrook facial grading scale is a comprehensive scale for the evaluation of facial paralysis patients. Its results greatly depend on subjective input. This study aimed to develop and validate an automated Sunnybrook facial grading scale (SBface) to more objectively assess disfigurement due to facial paralysis. Methods An application compatible with iOS version 11.0 and up was developed. The software automatically detected facial features in standardized photographs and generated scores following the Sunnybrook facial grading scale. Photographic data from 30 unilateral facial paralysis patients were randomly sampled for validation. Intrarater reliability was tested by conducting two identical tests at a 2-week interval. Interrater reliability was tested between the software and three facial nerve clinicians. Results A beta version of the SBface application was tested. Intrarater reliability showed excellent congruence between the two tests. Moderate to strong positive correlations were found between the software and an otolaryngologist, including the total scores of the three individual software domains and composite scores. However, 74.4% (29/39) of the subdomain items showed low to zero correlation with the human raters (κ<0.2). The correlations between the human raters showed good congruence for most of the total and composite scores, with 10.3% (4/39) of the subdomain items failing to correspond (κ<0.2). Conclusions The SBface application is efficient and accurate for evaluating the degree of facial paralysis based on the Sunnybrook facial grading scale. However, correlations of the software-derived results with those of human raters are limited by the software algorithm and the raters' inconsistency.

The need for ASP(Application Service Provider) has evolved from the increasing costs of specialized software that have far exceeded the price rage of small to medium sized businesses. There are a lot of technologies that make ASP possible, and software streaming service is one of them Software streaming is a method for overlapping transmission and execution of stream-enabled software. The stream-enabled software is able to run on a device even while the transmission/streaming of the software may still be in progress. Thus, a user does not have to wait for the completion of the software's download prior to starting to execute the software. In this paper, we suggest the new concept of software streaming system implement using the PageFault Interrupt Routine Hooking. As it is able to efficiently manage application, we do not have to install the entire software. In addition, we can save hardware resources by using it because we load basic binaries without occupying the storage space of the hardware.

As the most common application development of software development time, error-free quality, adaptability to frequent maintenance, such as the need for large and complex software challenges have been raised. When developing web applications to respond to software reusability, reliability, scalability, simplicity, these quality issues do not take into account such aspects traditionally. In this situation, the traditional development methodology to solve the same quality because it has limited development of new methodologies is needed. Quality of applications the application logic, data, and architecture in the entire area as a separate methodology can achieve your goals if you do not respond. In this study secure coding, the big issue, web application factors to deal with security vulnerabilities, web application architecture, design procedure is proposed. This proposal is based on a series of ISO/IEC9000, a web application architecture design process.

Open Source Software has over 60 percent of application software development but previous studies of objective quality model and characteristic to utilize Open Source Software appeared to be low and there are few studies regarding quantitative evaluation methods to evaluate Open Source Software. To solve these problems, in this paper, we propose a quality evaluation model, "Logical Open Source Software quality model", which is able to utilize for developing and maintaining application software and quantitative quality evaluation method that can utilize in the proposed model. The proposed Open Source Software quality model derives quality characteristics based on literature and it forms six main-features and twelve sub-characteristics by comparing with the quality characteristic of ISO/IEC 9126 and twelve evaluation metrics that can measure the metrics and the characteristics quantitatively. To verify efficiency of the proposed quality evaluation model, we apply the proposed quality evaluation to top 5 project management system (PMS) software in open source software community and prove its availability.

The software pattern is knowledge representation derived from the verified solutions or the experience of the experts. On account of the design varieties of software development, however, it is not the facilitated task to discover the best proper software pattern. This situation requires that software patterns be categorized in terms of their innate concepts. This paper proposes software pattern ontology(SPO) for the systematic categorization of software patterns by means of conceptual properties of patterns after the comparative analysis of association between software pattern and ontology. The SPO presented in this paper can establish the basis for the software pattern management system at the conceptual level. This paper also shows an idea for the application by unifying conceptual properties of software pattern and ontology.

The spontaneous interoperation is an important characteristic of ubiquitous applications and is closely related with mobility. The mobile components in ubiquitous environments are liable to appear in and disappear from one physical space to another. Because this characteristic certainly influences the structure and behavior of applications, they should adapt themselves to the changed environments by configuring their structure and behaviors. Consequently, developers are faced with the above challenging issue when they design and implement ubiquitous applications. The role concept is an efficient tool to model participant entities, their relationship, and collaboration, so role-based model are appropriate to describe a structure and behavior of software system. But, little attention has been given to reflect characteristics of ubiquitous applications. To tackle the problem, this study considers a ubiquitous application as a software organization which consists of software components and proposes an enhanced role-based application model for supporting spontaneous interoperation.
