Large software systems are being produced with a noticeably higher level of quality with component-based software engineering (CBSE), which places a strong emphasis on breaking down engineered systems into logical or functional components with clearly defined interfaces for inter-component communication. The component-based software engineering is applicable for the commercial products of open-source software. Software metrics play a major role in application development which improves the quantitative measurement of analyzing, scheduling, and reiterating the software module. This methodology will provide an improved result in the process, of better quality and higher usage of software development. The major concern is about the software complexity which is focused on the development and deployment of software. Software metrics will provide an accurate result of software quality, risk, reliability, functionality, and reusability of the component. The proposed metrics are used to assess many aspects of the process, including efficiency, reusability, product interaction, and process complexity. The details description of the various software quality metrics that may be found in the literature on software engineering. In this study, it is explored the advantages and disadvantages of the various software metrics. The topic of component-based software engineering is discussed in this paper along with metrics for software quality, object-oriented metrics, and improved performance.

The purpose of this paper is to show how much the subjects based on the mathematics and statistics contribute to the curriculum and the education of the students majoring in engineer of the Computer-Software department, and to recognize the roles of mathematics and statistics in the Computer-Software department. In order to advance the world-class Computer-Software department, it is necessary for Math/Stat to ensure the role as a basis for the Computer-Software majors as well as to extend its role to relate the core studies of the Computer-Software majors. Consequently, the recognition of Math/Stat in the Computer-Software major will enable to establish the short or/and long-tern plan for student education.

VOD 서비스는 초고속 인터넷을 이용하여 정보 서비스, 동영상 콘텐츠 및 방송 등을 실시간으로 제공하는 것이다. 본 연구에서 구현하는 VOD 시스템은 기존 인터넷망에 멀티캐스트 기술을 접목하여, 비트열변환 방식과 다수개 영상저장 방식을 비교한다. 이로부터 동영상을 각 가정의 PC에 고화질 주문형 비디오/영화, TV 등 다양한 고품질 서비스를 제공할 수 있을 것이다.

This paper relates to a software patent of a computer related invention, explains a describing method of software patent claim which can be registered software patent of computer related invention instead of computer program copyright which is the Intellectual Property about software since 1998 in the Korea Intellectual Patent Office(KIPO) by developing an information communication infrastructure technology and WWW technology. Also, it introduces an international and domestic trends of the software patent for computer related invention and related database for the software patent of the world and mentions advantage and disadvantage of software patent regime of each nation and the facing software patent problems as the Intellectual Property.

The necessity of a short period of software development with lower cost came out. The reason of making the component based development is that it can improve the software development , productivity maintenance , and software quality innovatively. Following these advantages of component based application development methods, we found the COM based components effective to Window platform in the satellite surveying. In this paper, we can obtain many precious engineering experiences. Software system development and maintenance will take much shorter time with higher reusability if satellite surveying system is constructed with component extraction proposed by us.

Software maintenance activities have always been important issues in many domains of the software industry. In order to help to resolve this issue, software modularization approaches have been studied to build adequate modules with high cohesion and low coupling; such modular structures can help the comprehension and maintenance of complex systems. In this paper, we propose a GUI-based automated approach for software modularization based on GUI structure analysis. GUI is a principal manner to allow users to access the overall functionalities of a software system; in particular, GUI is closely related to software functionalities, which makes it a promising tool to identify and understand the entire software system. We also implement a software tool to support our approach and evaluate it with a case study using an open source software.

Covid-19의 영향으로 직접적인 만남이 줄어들고 온라인 커뮤니티의 사용량이 급격하게 증가하였다. 에브리타임은 대부분의 대학생이 사용하고 있는 가장 보편적인 온라인 커뮤니티이다. 이러한 서비스와 비슷한 방식으로 운영되어 이질감을 느끼지 않으면서도, 직장인의 특성을 고려한 설계로 취업 후에도 지속적으로 사용할 수 있는 커뮤니티 서비스를 제안한다. 이에 본 논문에서는 협업기능을 강화한 직장인을 위한 온라인 커뮤니티이자 익명서비스로 프라이버시를 보호할 수 있는 모바일앱을 설계했다.

Reliability is one of the computable quality features of the software. To assess the reliability the software reliability growth models(SRGMS) are used at different test times based on statistical learning models. In all situations, Tradational time-based SRGMS may not be enough, and such models cannot recognize errors in small and medium sized applications.Numerous traditional reliability measures are used to test software errors during application development and testing. In the software testing and maintenance phase, however, new errors are taken into consideration in real time in order to decide the reliability estimate. In this article, we suggest using the Weibull model as a computational approach to eradicate the problem of software reliability modeling. In the suggested model, a new distribution model is suggested to improve the reliability estimation method. We compute the model developed and stabilize its efficiency with other popular software reliability growth models from the research publication. Our assessment results show that the proposed Model is worthier to S-shaped Yamada, Generalized Poisson, NHPP.

In this paper, we propose students' perception of software education according to the type of school. So, in this study, 47373 students were surveyed about the perception of SW education, and the results of the questionnaire were analyzed according to school type, gender, school level, experience of software education and event, and duration of software education experience. As a result, students attending software education lead schools showed the highest perception about software education, followed by software education research school and general school. In gender, males were more positive than females. The level of satisfaction and effectiveness of software education in school level was higher as the school level was lower, but the perception and career area of software education was higher as the school level was higher. In addition, software training and event experience have a positive effect on students' perception of software education, and the perception of software education changes positively as the duration of software education increases.

The basic goal of software development is to produce high quality software at low cost. Therefore, when to stop software testing and release the software product is a significant point in the software development. The software cost model is an effective tool used to help software developers control costs and determine the release time. In this paper, we discuss the cost model to apply all 6 models with consideration of time to remove errors, cost of removing each error and risk cost due to software failure. We show the impact of cost coefficients and parameter values on the expected total cost by changing the values and comparing the optimal release times.
