As the size and complexity of software systems increase, the design and specification of overall system structures become more significant issues than the choice of algorithms and data structures. Structural issues include the organization of a system as a composition of components; global control structures; protocols for communication, synchronization, and data access etc. In this paper we show why the existing software architectural description method is not satisfied, and suggest the necessity of the new architectural description language and the requirements of the software architectural description language.

Life-Cycle Cost is defined as a sum of the cost related to the purchase, possession, and use of products, system and service in a specific period. This means that life-cycle cost is a cost needed to possess and manage the facilities, production system and the products. Life-Cycle Cost analysis reflects the present and future cost of the official period. So, it becomes a tool that is used to evaluate and compare the alternatives. The fact that life-cycle cost analysis is a general tool that can express the many aspects of the cost and time in the standards of equivalent capital. This paper proposes the software life-cycle cost analysis methods by adapting the general analysis techniques to the software projects.

One of the biggest factors of software projects failure is that we can’t understand, analyze, document, manage, and control the complex requirements from various stakeholders. In other words, incorrect requirements and specifications have created many problems of unclear business purpose and scope, bad business forecasting, and the problem of low quality and it is possible to cause problems of the development cost. In order to solve these problems, a clear specification of requirements should be made. We suggest cost estimation method that utilizes successful bid difference challenges of SW business, which was determined by using a clear specification of such scope changes. First, the general business environment of SW scope modification and operational status are analyzed. Based on the results of this analysis, the key success factors of scope change management tasks and prerequisite information is derived. Finally, we suggest the cost estimation method taking advantage of the difference between successful paid bids.

Purpose: To evaluate clinical and radiological outcome of the full cementation technique in revision total knee arthroplasty (TKA) using a constrained condylar knee (CCK) prosthesis. Materials and Methods: Between January 2008 and March 2012, 18 cases (16 patients) of fully cemented revision TKA were performed using a CCK prosthesis. Fifteen cases of aseptic loosening (13 patients) and 3 cases of infection were included. There were 2 males and 14 females with a mean age of 76.7 years at the time of surgery, and the average follow-up was 81 months. Clinically, the pain score, function score and Hospital for Special Surgery (HSS) score were evaluated. Radiologically, loosening, radiolucent lines and migration of implant were evaluated. Results: Preoperatively, the pain score, function score and HSS score were 50.3, 24.4 and 61.8 points, respectively. At the latest follow-up, the scores were improved to 84.8, 63.6 and 85.6 points, respectively (p<0.05). Loosening or migration of implant was not observed in any cases. Radiolucent lines were observed in 5 cases underneath the tibial component without progression during the follow-up. Conclusions: The full cementation technique in revision TKA using a CCK showed excellent clinical results. Although radiolucent lines were observed in 27.8% underneath the tibial component, there was no progression to loosening or instability.

Software configuration management is identifying software items in the system that can be produced during the software life cycle. And it defines, creates, modify, distributes, reports the correction request for software items, manages in a single process. Effective software configuration management is to ensure consistency, and accuracy. In this study, we present the guideline for the entire configuration management process so that it can be managed consistently the configuration of software development artifacts, work procedures, artifacts. This study is based on the standard process(TTAS.KO-09.0038) of the public part SW business and the standard of life cycle process of software(ISO / IEC 12207 2008 software and system engineering life cycle). This guideline is configured to maintain the activities of ‘detailed instructions on software project management supervision’ and maintain mutual compatibility of them.

Now at the time in which software industry has become the core of national competitiveness, estimating the accurate budget at the initial phase of software business got recognized as one of the important factors in the success or failure of software business. This paper proposes improved software maintenance and operation cost estimation guideline in order to estimate more accurately after surveying realistic problems. It also defines the task of software maintenance and operation and sets the scope of them. It presents the model for fixed cost to make accurate estimation, which allow the regular task. Furthermore, it proposes the model for variable cost to make rational estimation, which allow the maintenance and문 operation jobs.

Software dimension reduction identifies the commonality of elements and extracts important feature elements. So it reduces complexity by simplify and solves multi-collinearity problems. And it reduces redundancy by performing redundancy and noise detection. In this study, we proposed defect severity-based dimension reduction model. Proposed model is applied defect severity-based NASA dataset. And it is verified the number of dimensions in the column that affect the severity of the defect. Then it is compares and analyzes the dimensions of the data before and after reduction. In this study experiment result, the number of dimensions of PC4's dataset is 2 to 3. It was possible to reduce the dimension.

One of the most important prerequisites for a successful software process is the collaboration and software requirements negotiation of all stakeholders in the software development process. Remote users using computer networks can negotiate software requirements by computer supported system, and can share their informations. The goal of software requirements negotiation system is an integration of all win conditions and an agreement after resolution of conflicts. The existing systems need an exclusive system and must be dependent on specific platform and network. Users must have the knowledge of all stakeholder's status and use homogeneous collaborating applications. This paper presents the Web-based software requirements negotiation system for the purpose of resolution of the existing systems' problems. The Web-based software requirements negotiation system can be driven by WinWin Spiral model, and it is based on hybrid execution method. The proposed system is validated and tested on heterogeneous environments.
