Variability management is the foremost criterion that defines the extent to which complexities can be handled in a system. Predominantly, the requirements' engineering (RE) study overlooks, or speculates a consistent behavior of, the environment in which a system functions. In real-time systems it is vital to observe and adjust to an intrinsically changing context. Therefore, in this work we identify the requirements of the system in various contexts by recommending a framework using i* goal model, problem frames, use case maps and live sequence charts. The framework is illustrated using a case study of the smart grid RTP system. In the case study, elaboration of scenarios using use case maps and live sequence charts proved beneficial as they assisted in early analysis and validation of contexts. In addition, the elaboration of requirements for obstacle and conflict analysis assists the requirements engineer to increase the robustness of the system. The proposed framework is evaluated theoretically and by empirical study.

ICT의 발달과 더불어 근로의 본질이 지식근로로 바뀌어 가고 있고, 따라서 시간과 장소에 구속되지 않고 좀더 자유롭게 ICT를 활용하여 업무를 수행하는 스마트워크가 확산되고 있다. 미래형 근로의 형태를 수용하고자 하는 스마트워크는 근무패러다임의 변화라서 정책적으로도 많은 변화가 요구되고 있다. 이러한 정책들의 근간 자료이자 현황과 변화의 추세를 파악하여야 하는데 이를 위해서는 스마트워크의 추진 정도, 또는 수준을 지속적으로 측정하는 지표 시스템이 필요하다. 이러한 측정 지표의 개발을 위해서는 복합적인 개념인 스마트워크를 좀더 정교하게 정의하고 이와 관련된 지표들을 총괄하는 프레임워크 도출이 선행되어야 한다. 본 연구에서는 국내외에서 시행되고 있는 스마트워크 관련 조사들의 내용들과, 선행 학술 연구문헌들을 취합 분석하여 스마트워크의 개념을 정의하고 스마트워크의 수준을 측정하기 위한 기본 프레임워크를 제시하고 있다.

The flow of time, depending on the company's ongoing business link to guarantee the proportion of much greater importance, it in the organization as part of an enterprise-wide level, rather than acting on the information society has been considered as the topic of race. Information Security Governance, the integrity of the information, service continuity, the three kinds of information asset protection purpose begins. It is essential for corporate governance, transparency should be part, must be aligned with the IT framework. Existing information security governance framework that small businesses a wide range of governance issues and interests have never had. Therefore, we simplified the information security governance framework is proposed, and solve problems, and propose a framework for analysis of the safety and efficiency through the analysis of the effectiveness of the proposed method were discussed.

The market for compact houses is growing due to the demand for floor plans prioritizing user needs. However, clients often have difficulty communicating their spatial requirements to professionals including architects because they lack the means to provide evidence, such as spatial configurations or cost estimates. This research aims to create a framework that can translate sketched data-driven spatial requirements into 3D building components in BIM models to facilitate spatial understanding and provide building performance analysis to aid in budgeting in the early design phase. The research process includes developing a process model, implementing, and validating the framework. The process model describes the data flow within the framework and identifies the required functionality. Implementation involves creating systems and user interfaces to integrate various systems. The validation verifies that the framework can automatically convert sketched space requirements into walls, floors, and roofs in a BIM model. The framework can also automatically calculate material and energy costs based on the BIM model. The developed frame enables clients to efficiently create 3D building components based on the sketched data and facilitates users to understand the space and analyze the building performance through the created BIM models.

In this paper, we investigate and analyze the application of VV&A on the development of war-game models which were developed in Korea. Then we propose VV&A framework which comprises VV&A basic model, VV&A reference model and a supporting tool. The VV&A basic model consists of VV&A process, products and methodologies. The VV&A reference model includes VV&A check lists for each VV&A activities, an assessment model of VV&A execution level and VV&A process maturity model. The VV&A supporting tool is to document and manage VV&A products. The proposed VV&A framework can be used as the foundation of VV&A plan on its execution.

The user interface is the medium, which provides the users to have an access to the web-based information system. The user interface is the means of improving usability and accessibility for the user, as well as being the core component in the web-based information system. In this paper, the audit framework of the user interface was developed to upgrade the usability and accessibility; it was based on the three basic components of the current audit framework in the web-based information system. At the time of an audit, the UI process of the 'Analysis', 'UI Design', 'UI Production', and 'Test' was defined, which was analyzed through the web development methodology. Also, for the area of an audit, the 'Information', 'Design', and 'Technology' were defined by the analysis of the components that makes up the user interface, From the view of an audit, the standard criteria of an assessment were set as 'Usability', 'Accessibility', and 'Cross Browsing'. Through the framework that was proposed in this paper, practical audit applies the performed examples. By this, the efficiency of the proposed framework was verified.

The tactical employment is a critical factor to win the war in the modern battlefield. To apply optimized tactics, it needs analyses related to a battle system. Normally, M&S (Modeling & Simulation) has been studied to analyze data in general problems. However, this method is not suitable for military simulations because there are many variables which make complex interaction in the system. For this reason, we suggested the optimized simulation framework based on the M&S by using DPSO (Discrete binary version of PSO) algorithm. This optimized simulation framework makes the best tactical employment to reduce the searching time compared with the normal M&S used by Monte Carlo search method. This paper shows an example to find the best combination of anti-torpedo scenario in a short searching time. From the simulation example, the optimized simulation framework presents the effectiveness.

Capacity of modem storage devices is becoming larger than yesterday and integration of disk is increasing. It refers that physical errors can damage a lot of digital information on storage devices. So we propose file system test framework in this paper to test integrity and robustness of file systems. We develop the tool for generating bad sectors on disks and the tool which creates all physical errors defined in storage devices. We also develop the tool for immediately monitoring the condition of read and write execution on storage devices. So, by integrating those tools, we develop FORT, test framework for confirming robustness of file system. We analyze robustness of ext3 file systems by FORT. Lastly, we present draft of intelligent system merging file system and device driver's layer architecture.

Banks are preparing the system for the new concept of the 2020's. The framework of the core-banking solution is that various demands must be accommodated. In addition, the development process of new system must solve problems, such as obtaining the economic feasibility and expandability as well as minimizing the risk elements. This study verified the superiority of converging framework by analyzing the framework of new converging core-banking solution that can accommodate the current core-banking solution and future requirements. In addition, the study proposed application methods and the pros & cons of a converging framework. The migration effects and successful elements for changing to a new system are proposed.

In this paper, in order to improve the execution performance and serviceability of cross-platform applications frameworks based on the existing web applications, we design and implement a new hybrid application framework named as WApplE.js, which enables direct control of native UI(User Interface) of mobile operating systems and various resources via JavaScript. We first present the design results for the overall software structure and the configuration of every layer of WApplE.js, and then analyze the processes for calling and handling APIs in the implemented hybrid application framework. In addition, the results of comparison of features to the existing frameworks are presented.
