The recent years, the cloud-based paradigm of cloud services are developed rapidly, it come with many a new problems. However, the collaboration between a individual with other users is still difficult. Cloud service is considered when users need to take advantage of security and the availability of cloud services. In this paper, we proposed an detection framework to detect an intrusion attack that threaten to cloud-based collaboration services and cloud security. Identify vulnerabilities and prepare for the safety of the collaboration services to create a variety of content in the cloud, it help to prevent the threats.

With Internet of Things (IoT) technology, home environment becomes smarter than ever. Not only smart devices such as smart phone or smart TV, but also various IoT devices including sensor, smart thermostat, and smart scale has now become very common on the market. These devices have connectivity to the Internet, so that user can read data from the device or control the device using Internet technology. However, due to diversity of smart home requirements, device collaboration in smart home remains a challenging task still. Usually smart home is built with various technologies to fulfill its own purpose, and these purposes cover very wide area from controlling low-power sensor devices to controlling high-performance devices like smart TV and smart phone. This variety of smart home requirements makes smart home very complicated due to mixed network architecture, protocol and technology. In this paper, a framework to enable managing and collaborating heterogeneous IoT devices in smart home environment is proposed. Several programming models are defined in the proposed framework to make application development for heterogeneous devices more intuitive. The proposed framework has been implemented as a web service, and a case study with real-world smart home IoT devices is presented.

최근 대부분의 대규모 기업정보시스템은 기능재활용성, 다종의 시스템 리소스, 다중 플랫폼 등을 지원하기 위해 다층구조의 미들웨어 또는 프레임워크를 기반으로 하고 있다. 그러나 이러한 다층 및 다중 플랫폼 분산 구조는 미들웨어간의 컴포넌트 및 메타정보에 대한 상호운용성 문제를 제기한다. 본 논문은 추상화 프로그래밍 스타일과 XML-SOAP에 기반한 컴포넌트 보존 방법을 통해서, 다종의 리소스를 지원하고 플랫폼에 독립적인 컴포넌트 기반 개발을 가능케 하는 객체지향프레임워크 SOAF (Simple Object Application Framework)을 제시하고 그 아키텍쳐 및 주요 특징에 대해 소개한다.

J. Zhou 등이 제안한 공개키 프레임워크는 인증서의 유효 기간은 여러 짧은 갱신 기간으로 나뉘어 지며, 각 인증서는 인증서 소유자(또는 조직적인 환경에서는 소유자의 관리자)의 제어를 통하여 각 갱신 기간의 종료 지점에서 취소될 수 있다. J. Zhou 등의 공개키 프레임워크는 인증서 검증자의 계산 및 통신 부담을 줄임으로써 효율성을 상당히 증진시키지만 실제 환경에 구현하여 적용할 경우 많은 문제점을 내포하고 있다. 따라서, 본 논문에서는 J. Zhou 등의 공개키 프레임워크 내의 보안 파라메타들을 재조명한 후, 실제 구현 환경에 적합하도록 개선하며, J. Zhou 등의 공개키 프레임워크에서 불필요한 신뢰기관을 제거함으로써 보다 실용적인 공개키 프레임워크를 제안한다. 그리고, 개선된 공개키 프레임워크를 기반한 실질적인 응용을 소개한다.

Purpose: The purpose of this study was to design a framework for generating one-class classification algorithm based on Hyper-Rectangle(H-RTGL) in a distributed environment connected by network. Methods: At first, we devised one-class classifier based on H-RTGL which can be performed by distributed computing nodes considering model and data parallelism. Then, we also designed facilitating components for execution of distributed processing. In the end, we validate both effectiveness and efficiency of the classifier obtained from the proposed framework by a numerical experiment using data set obtained from UCI machine learning repository. Results: We designed distributed processing framework capable of one-class classification based on H-RTGL in distributed environment consisting of physically separated computing nodes. It includes components for implementation of model and data parallelism, which enables distributed generation of classifier. From a numerical experiment, we could observe that there was no significant change of classification performance assessed by statistical test and elapsed time was reduced due to application of distributed processing in dataset with considerable size. Conclusion: Based on such result, we can conclude that application of distributed processing for generating classifier can preserve classification performance and it can improve the efficiency of classification algorithms. In addition, we suggested an idea for future research directions of this paper as well as limitation of our work.

With the recent popularity of smartphones, many games are being developed on mobile-based platforms. As a result, it has brought about many changes in the way mobile game is developed. Especially mobile platforms, which are divided into Android and IOS, can now be applied to each platform without additional development through cross-platform. This means that it is necessary to move away from the method of developing each using separate development tools and implement the development process through cross-platform unique features. In this paper, we studied various methods to increase the productivity and quality of game development for the development of mobile games, and a formal framework considering the development process was developed. The framework consists of process, development domain, and platform support parts, each playing its own role. Items of the detailed framework must be reflected so that detailed response data for efficient application of game development can be established in actual mobile game development. The framework was developed by approaching it from two domains, the need for a framework and the framework implementation of key item response data.

Radio frequency identification (RFID) is an established technology and has the potential, in a variety of applications, to significantly reduce cost and improve performance. As RFID-enabled applications will fulfill similar tasks across a range of processes adapted to use the data gained from RFID tags, they can be considered as software products derived from a common infrastructure and assets that capture specific ions in the domain. This paper discusses a framework that supports the development of RFID-enabled applications based on a business process family model (BPFM), explicitly representing both commonalities and variabilities. To develop this framework, common activities are identified from RFID-enabled applications and the variabilities in the common activities are analyzed in detail using variation point concepts. Through this framework, RFID data is preprocessed, and thus, RFID-enabled applications can be developed without having to process RFID data. Sharing a common model and reusing assets to deploy recurrent services may be considered an advantage in terms of economic significance and the overall product quality afforded.

CALS is a global information strategy which may be viewed as the industrial or manufacturing lane on the Information Highway. The basic vision of CALS is to improve costs, timeliness and quality through information automation and integration. This paper present a CALS implementation framework that incorporates organizational environment, CALS standard, process innovation and information systems. The implementation framework of CALS guides an organization to gain perspective in a complex CALS area and provides insights for academicians in identifying where research needs to be performed. A case study was used to provide the insight how a CALS implemention framework is being used. The case was analyzed according to the framework we proposed.
