Analysis of carrying capacity and site suitability by the systematic application of environmental information an provide a basis for implementing environmentally sensitive and sustainable resource development policies. Based on the availability of public services and environmental and site-specific constraints, a Rural Residential Density Matrix was applied in Santa Cruz County, California, USA to assess the development potential of rural land parcels since 1980. In one case, the Matrix was applied to calculate the allowable development density on a site in Lompico planned for use as a Buddhist retreat center. These calculations revealed higher environmental sensitivity and lower carrying capacity than projected in the proposed plan. Under the constraints of the county's minimum acreage policies and insufficient developable land, the developer cancelled the proposed plan. This example suggests that application of the Matrix at the concept development stage would increase the effectiveness of the prior environmental review and environmental impact assessment (EIA) system in Korea.

The paper is design and implementation of the system to support security communication between a Web Browser and a CGI program by a Web Server using PKI(Public Key Infrastructure. This system uses GSS(Generic Security Service)-API to communicate with PKI, offers a Web user a Client Proxy, and offers a CGI developer there library functions related with security. TLS(Transport Layer Security) supports security communication between a Web Browser and a Web Server, but the system supports security communication between a Web Browser and a CGI program as the protected data received from a Client Proxy are sent to a CGI program, and the CGI program decrypts the data using the library functions supported by this system.

Hearing-impaired people are increasing rapidly due to the global aging trend. Early detection of hearing loss requires an easy-to-use audiometry device for the public. Existing audiometry systems were developed as PC-based, PDA-based, or smartphone apps. These devices were often dependent on specific software platforms and hardware platforms. In this paper, we tried to improve software platform compatibility by using cross platform, and tried to implement IoT-based pure tone audiometry device which does not require sound pressure level correction due to hardware differences. Pure tone audiometry is available in a variety of ways depending on the type of hearing loss and age. Using the IoT-based audiometry device implemented in this paper, it will be possible for an app developer who lacks hardware knowledge to easily develop an app with various scenarios for hearing screening. The results of this study will contribute to overcoming the software and hardware dependency in the development of IoT-based healthcare device.

Current web accessibility checks and automatic assessments have been pointed out that the assessment items and scores are evaluated from the developer's point of view rather than from the user's one. In addition, although most of the grades of an automatic assessment on the public web sites are excellent because they are built in accordance with the web accessibility development guidelines, not a few web sites shows relatively low grades in evaluating their usability test made by those users. Taking into account the inadequacy of these web accessibility assessments, this study has identified the differences between the grades of usability evaluations and automatic evaluations for people with low vision and analyzed the major factors affecting web accessibility usability evaluations using Repertory Grid Techniques. Also, the Hard Laddering method of the Means-End Chain theory was adopted to visualize the relationship between Attributes-Conferences-Value and a hierarchical value system analysis based on FGI(Focused Group Interview) to people with the low vision. This study proposed the measures to improve the current web accessibility automatic assessment allocation, expert evaluation criteria, and user task assessment. In particular, it is a web accessibility user evaluation model that can consider the web accessibility quality certification criteria and user review assessment by directly analyzing the user cognitive structure and value system. This study is expected to be useful as a research to enhance the quality of web accessibility assessment.

This article starts with a review of the system characteristic(easiness, flexibility, reliability) and individual characteristic(self-efficacy, achievement motive, computer ability) through education satisfaction especially in relation to the education performance(perceived usefulness, educatee value). We found that all variables significantly affect the education satisfaction, but only computerized ability doesn't significantly affect the education satisfaction. Education satisfaction significantly affect the education performance. This paper suggests that the followings; first, response time of systems is valuable factor in KcLep. Second, self-efficacy and achievement motive are more important then computer ability in KcLep educatee. Finally, software developer and teacher always think about rapid response time of systems and exchange of data for the education performance in KcLep.

Locals' initiating the community making projects is considered as a good approach in terms of the effectiveness, sustainability and government's budget. But there are not the local institutions' support, while local people alone may face difficulties in starting and managing the projects. This study is to explore the roles of the institutions for starting and managing the family-friendly communities. For this purpose, 18 secondary source cases from the livable community making projects were analyzed. And the major findings of this study were as follows: The (local) institutions need to gain credibility from the locals before starting the family-friendly community project. In the motivation steps, the institution performs the role of a proposer, a survey researcher, an opinion gatherer and mediator. In the systematization steps, the institution needs to perform as a mentor, a developer of human and non-human resources, a conflict mediator, an education practitioner, an instructor, a networker, and an administrative staff. In the execution steps, the institution needs to perform as a cultural program planner, a public relations personnel, and an assessor. In conclusion, the institution needs to train community coordinator and develop programs to educate local residents for the effective family-friendly community projects.

Android is now the most popular smartphone platform and remains rapid growth. There are huge number of sensitive privacy information stored in Android devices. Kinds of methods have been proposed to detect Android malicious applications and protect the privacy information. In this work, we focus on extracting the fine-grained features to maximize the information of Android malware detection, and selecting the least joint features to minimize the number of features. Firstly, permissions and APIs, not only from Android permissions and SDK APIs but also from the developer-defined permissions and third-party library APIs, are extracted as features from the decompiled source codes. Secondly, feature selection methods, including information gain (IG), regularization and particle swarm optimization (PSO) algorithms, are used to analyze and utilize the correlation between the features to eliminate the redundant data, reduce the feature dimension and mine the useful joint features. Furthermore, regularization and PSO are integrated to create a new joint feature mining method. Experiment results show that the joint feature mining method can utilize the advantages of regularization and PSO, and ensure good performance and efficiency for Android malware detection.

The Web accessibility compliance rate of public organizations and private enterprises is still low due to the lack of awareness of Web accessibility by website developers and managers in spite of the fact that web accessibility compliance became mandatory in 2008. Web developers and managers think the website visual quality might be compromised or the website requires more development time and budget in order to comply with the web accessibility guidelines. Therefore, this paper has analyzed whether developers with various training in web accessibility or experience on website development have different perception on time, cost and design issues for developing accessible websites. For this purpose, 72 Web developers with hand-on experience working for website development companies in Korea were sent to the questionaries. The results have indicated that the group of developers with many hours of training in web accessibility and rich experience on website development perceives that they can develop accessible website without additional cost and time or compromising design quality. The contributions of this paper are following： (1) proving the widely recognized perception on budget, time, and design for developing accessible website is incorrect and (2) motivating further research on this subject in the future.
