The Agile methodology is a new trend in software development. Nowadays enterprises have been adopting the agile methodology in an effort to deal effectively with rapidly changing user requirements. In most cases, much improvement was accomplished in the software development. Some studies have mentioned that the motivation of software developers is a contributing factor on the improvement. However, it is not known yet what aspects of the agile methodology get them to be motivated. The aims of this study are the comparison between the traditional methodologies and agile methodology and look into potential motivation of software developer and their jobcharacteristics. For the empirical analyzing, research data were collected by 77 developers of 4 domestic IT companies. The analysis shows that there is significant differences on developer's potential motivation according to what kind of methodology is used. Agile developers to be more motivated than others methodologies developers. It also shows in detail that what kinds of job characteristics of developer are different among them depending on methodologies.

인터넷이 점차 보급되면서 오늘날의 대부분의 소프트웨어들이 인터넷을 기반으로 하는 분산 어플리케이션으로 변해가고 있다 코바라는 미들웨어를 사용하여 개발하는 방식이 이러한 웹 기반 소프트웨어 개발을 쉽게 해줄 수는 있지만, 소프트웨어의 완성 단계에서 최적화된 소프트웨어의 분산을 도와줄 수 있는 성능검증 방법이 제시되지 않고 있다. 또한, 분산 시스템의 운영 단계에서 동적으로 부하를 조절 하기위한 모니터링 기법이나 부하 분산을 위한 메트릭스가 제시되지 않고 있다. 본 논문에서는 코바 어플리케이션의 실행 사에 객체간의 메시지를 모니터링 할 수 있는 기법과 부하 메트릭스, 부하분산을 위한 메트릭스를 제시한다. 부하를 계산하기위해 어플리케이션에서 발생하는 이벤트들과 그 이벤트들 간의 시간 을 정의하여 부하와 관계있는 데이타들을 추출한다. 추출된 데이타들로부터 부하를 계산하는 공식을 유도 하고 계산된 부하들을 이용하여 부하 분산 메트릭스를 제시한다. 또한 구현사례를 통하여 제시된 모니터링 알고리즘 및 부하 메트릭스와 부하 분산 메트릭스의 적용성과 효율성을 살펴본다.

This study addresses basic requirements for mathematical programming software, discusses considerations in designing these software, implementation issues facing in these types of applications development, and shows some examples of codes being developed in the course. This type of projects requires long and ever-changing evolutionary phases. The experience is therefore, valuaable in suggesting some useful hints which may be salvaged for similar projects as well as providing reusable codes. In particular, scanning and parsing the free-format inputs, symbol table management, mixed-language programming, and data structures dealing with large sparse matrices are indispensable to many management science software development. Extensions to be made are also discussed.

When we conduct development of a large-size SI project, it is highly necessary to utilize an appropriate application framework which helps to build a qualified software with high productivity in a short period of time. In this paper, we propose the architecture of a dynamically reconfigurable CBD application integration framework that has been used for developing large-scale e-business applications to achieve high development productivity and maintainability. This Integration framework can easily extend its functionalities, and dynamically change its configuration during run time according to the business category, such as applying interaction patterns among main components in software architecture, rules, policies, and environmental parameters. Dynamic reconfiguration has the feature to make applications be easily customized for changeable requirements. Through our application integration framework, huge sizes of contents can be managed according to the business category as well, by keeping configuration informations and huge volumes of source codes. In order to evaluate out application integration framework in terms of performance criteria, we present experimental results of throughputs from the framework by yielding dynamic configuration without any performance degradation.

GIS provides the various analyzing and displaying using diverse spatial data have supported the powerful functionality and friendly user-interface. But, early GIS software is developed as package tool, it have many difficulties with reducing the cost of developing GPS application and satisfying the various user requirements. At present, the developed GPS applications across multiple domains, despite the common features are built separately for each domain in terms of software engineering development followed out waste of time and money expenditure. However, common features between GPS applications, if deployed as a component assembly and reuse components in terms of enabling the two kinds of component-based development can bring out the beneficial results. In this paper, we described the Analysis and design of GPS ApplicationsS based on Component. Each GPS component is composed of many objects accomplish the atomic service processing and cooperate with each other. And, GPS components meets the qualifications of thc low cost of developing GPS application because of the reusability and re-composition.

In the 4th industrial revolution, there are many projects for diverse software applications of smart city environments. Most of the stakeholders focus on considering software quality for their developed software. Nobody doesn't guarantee requirement satisfaction after complete development. At this time, we can only work on user acceptance testing for requirement satisfaction on frequently changing requirements. Why keeps the requirement traceability? This traceability is to identify risks related to requirements, to assure correct software development based on customer requirements. To solve this, we are researching how to implement requirement traceability across each artifact's relationship to each activity of a whole development lifecycle.

Project management and deployment has gone through a long journey from traditional and agile to continuous integration, continuous deployment and continuous monitoring. Software industry benefited with the latest buzzword in the development process, DevOps that not only escalates software productivity but at the same time enhances software quality. But the implementation and assessment of DevOps practices is expository as there are no guidelines to assess and improvise DevOps application in software industries. Hence, there was a need to develop a hybrid model to assist software practitioners in DevOps implementation. The intention behind this paper is to implement the already proposed DevOps hybrid model using suggested tool chains including Jenkins, Selenium, GitLab, Ansible and Nagios automation tools through Jenkins project management environment and plugins. To achieve this implementation objective, a java application is developed with a web-based graphical interface. Further, in this paper, different challenges and benefits of Jenkins implementation shall also be outlined. The paper also presents the effectiveness of DevOps based Model implementation in software organizations. The impact of considering other automation tools and models can also be considered as a part of further research.

Since Richard Feynman presented the concept of quantum computers, quantum computing have been identified today overcoming the limits of supercomputing in various applications. Quantum hardware has steadily developed into 50 to hundreds of qubits of various quantum hardware technologies based on superconductors, semiconductors, and trapped ions over 40 years. However, it is possible to use a NISQ (Noisy Intermediate Scale Quantum) level quantum device that currently has hardware constraints. In addition, the software environment in which quantum algorithms for problem solving in various applications can be executed is pursuing research with quantum computing software such as programming language, compiler, control, testing and verification. The development of quantum software is essential amid intensifying technological competition for the commercialization of quantum computers. Therefore, this paper introduces the trends of the latest technology, focusing on quantum computing software platforms, and examines important software component technologies.

현재 새롭게 개발되는 소프트웨어는 50% 이상이 분산 플랫폼에서 개발되고 있다. 또한 분산 컴포넌트 기반의 소프트웨어 개발을 가능하게 하는 EJB(Enterprise Java Beans)[1] COM(Component Object Model )[2]. CORBA(Common Object Request Broker Architecture)[3] 와 같은 기술이 급격히 발전하고 있다. 따라서 분산 플랫폼 상에서 컴포넌트 기반의 응용 소프트웨어 개발을 위한 체계적인 개발 프로세스가 요구된다. 그러나 현재의 일반적인 컴포넌트 기반 소프트웨어 개발 방법론은 각 작업들간의 관 계와 각 작업의 산출물간의 관계를 명확히 제시하지 않는다. 또한 분산 응용 소프트웨어 개발에 있어서 고려되어야 할 분산 이슈에 대해서도 체계적으로 다루지 않고 있다. 본 논문에서는 분산 컴포넌트 기반의 응용 소프트웨어 개발을 위한 분석 및 설계 방법을 제시한다. 본 논문에서 제시하는 방법에서는 UMI 기반의 프로세스인 Unified process를 바탕으로 하여 체계적인 개발 지침과 산출물의 관계를 제시한다 또한 플랫폼과 프로그래밍 언어에 독립적인 CORBA 환경을 고려하여 성능. 결함 방지, 안전성, 분산 트랜잭션의 분산 이슈를 명시적으로 다루는 지침을 제시한다.
