Cloud Computing is emerged as an effective reuse paradigm, where service providers operate hardware and software and as a service, and service consumers invoke the service through Internet. Software-as-a-Service (SaaS) is a type of cloud services, where the whole software is designed as a service so that several consumers can reuse the SaaS. While tradition software applications are developed for a specific organization, SaaS is developed for multiple users in the various organizations. Hence, reusability is very essential characteristic of SaaS. Reusability is defined as a metric of how effective and efficient software functionalities can be used by various users. Reusability in SaaS is evaluated by considering three sub-characteristics; applicability, adaptability, and scalability. Since such a SaaS has considerable differences and characteristics from traditional software applications, conventional methods including object-oriented modeling, component-based development method, and service-oriented architecture (SOA) service development method would be limited in developing services which can fulfill these three sub-characteristics related to reusability as well as SaaS-intrinsic characteristics. Hence, there is a great demand for effective processes for developing SaaS cloud services. In this paper, we present a practical process for developing SaaS, which focuses on ensuring reusability. And by performing a case study with our proposed SaaS development process, we evaluate applicability of our proposed process and explain how the process is used in a real domain. Then, we compare our proposed process with others for verifying our study. Through the proposed process, cloud services with high quality can be more effectively developed.

Product line engineering (PLE) is one of the most recent and emerging reuse approaches in software engineering. Core asset, which is a reusable unit of PLE, is shared by several members in a product line (PL). So, developing a well-defined core asset is a prerequisite to increase productivity and time-to-market. Existing PLE methodologies emphasize the importance of core asset but mainly focus on analyzing core asset. And, several processes for designing core asset do not fully cover all elements of core asset which is from product line architecture (PLA) to decision model and need to augment systematic process, detailed instructions, and templates of artifacts. These problems result in difficulty with designing core asset and applying PLE. In this paper, we present an overall process and templates of artifacts to design core assets. And, we apply proposed process to a case study in order to show its applicability. With the proposed process, detailed instructions, and templates of artifacts, we believe that we can more systematically and more easily design high-quality core assets and we fully cover product line architecture, component, and decision model when designing a core asset.

신 차종의 개발 시, 기존 차량 모델을 사용하여 재 설계하는 방식에 의해 전례 없이 빠르게 차량 개발을 수행하고 있다. 또한 대부분의 이들 후속 차량은 공통 플렛폼 상에 설계되고 있으며, 일반적으로 충격, 구조 건전성, 생산 타당성 검토 등의 컴퓨터 시뮬레이션은 개발 프로세서 초기 단계에서 행하여 지고 있으나. NVH 엔지니어링은 차량 개발 프로세스의 매우 중요한 과정으로 되어 있음에도 불구하고, 실내 소음, 진동 승차감, 피로 수명 예측 등은 사용되는 해석 모델의 크기 및 복잡성으로 인하여 이들 성능 특성 평가 및 최적화는 아직 도전 과제이며, 본 논문에서는 몇몇 선진 OEM에서 수행되고 있는 NVH 개발 프로세스와 이를 가능케 하는 기법을 소개한다.

With the growing concern over frequent occurrences of criminal events, help-requesting mobile applications have drawn attention. However, existing applications solely focus on providing help-requesting services. Therefore, in this paper, we design and implement a help request and response process which allows users to request help by sending messages and locating their friends, acquaintances and even near-by application users, and to allow help be reached by forwarding messages. This application is composed of three parts: help-requesting, help-responding, and checking-status. This application is developed on the Android platform where we exchange users' longitude and latitude through web server communication. We conducted test to verify the effectiveness of the forwarding function, and it has been confirmed that 93.33% of subjects used the forwarding function to help users at risk.

This study is redesigned library acquisition process to migrate library offline process to online applying the concepts of BPR(Business Process Reengineering), Business Process and Workflows in electronic commerce, and UML that is a one of visual modeling methods was applied to new model form software development. The new model can be processed library’s acquisition process efficiently and rapidly. And library and information center would migrate their back office work from offline to online using this model, so that new roles for librarian in the digital age will be created. The directions of digital library research should be accepted various application technologies like electronic commerce to get synergy effect in the near future.

컴포넌트 기반 기술의 장점을 최대로 살리기 위해서는 컴포넌트 기반 개발 프로세스 및 관리 프로세스가 체계적으로 통합 관리되어야 한다. 체계적인 개발 프로세스의 부재 속에서 개발된 컴포넌트는 자신의 최대 이점인 소프트웨어의 재사용과 품질의 향상을 끌어내지 못하기 때문이다. 이에 본 리포트에서는 체계적인 개발 프로세스에 대한 Opportunity Tree를 제안함으로써 컴포넌트를 개발하고자 하는 이들의 CBD에 대한 이해를 높이고, 개발 과정의 주요 프로세스를 효과적으로 수행할 수 있도록 한다.

As the knowledge-based society hot been constructed, the size of work process that has to be done grows big and the amount of the information that has to be analyzed increases. In the paper business process can be accurately executed by the rule agent to manage precise rules and definitions to be needed by execution of process for management of business process. And individuals con accurately measure and manage personal schedules to execute process through supporting the agent of schedule management. The model is designed and implemented for organization to improve process of control, flexibleness, agility, reliability, and reuse through business process automation and removing process overlapping and for personal to improve measuring personal process capacity and distinguishing process weak points.

With the revision of the Public Records Management Act in 2020, it has become possible to appraise long-term records more than 30 years old in the record center. However, there was no discussion on the appraisal process except for the revision of the Public Records Management Act. This study aimed to propose a process for appraisal of long-term records in the record center, focused on the roles and functions of the record center, archives, and central archives. To confirm the status and problems of the records appraisal process, we analyzed record management standards and interviewed 4 archivists who have been working as specialists for over 10 years. Based on the analysis results, the appraisal process for long-term records in the record center was redesigned in consideration of the functions and roles of the record center, archives, and central archives.

본 연구는 비즈니스 프로세스 리엔지니어링(Business Process Reengineering : BPR)의 분야에서 제기되고 있는 여러 가지 지침들을 종합.분석하였다. BPR 구축을 위한 단계를 분석(Analysis), 재설계(Redesign), 실행 (Implementation)으로 구분하여 각 단계별 지침들을 분석하였으며, 이러한 지침들이 조직구성요소중 어떤 요소에 영향을 미치는지를 분석하였다. 또한 각 단계의 지침들이 비즈니스 프로세스 리엔지니어링을 통하여 개선하고자 하는 성과 측정의 주요 요소인 품질(Quality), 비용(Cost), 속도(Speed), 서비 스(Service)의 측면에서 어떤 요소에 영향을 미치는지를 파악하였다. 이를 통 하여 BPR 구축의 기본적인 틀과 구조적 지침을 제시하고 있으며, 향후의 실 제적 적용 및 연구들이 나아가야 갈 방향을 제시하고 있다. 본 연구를 통하 여 기존의 연구에 대한 현황과 한계를 발견하였다. 첫째, 기존의 많은 연구 들은 BPR의 재설계 측면을 위주로 한 연구이며, 구체적이고 실천적인 지침 들을 제시하지 못하고 있다. 둘째, 실행단계에서는 주로 추상적인 지침들을 제시하고 있다. 셋째, 재설계 단계에서는 조직의 문화적인 측면이 별로 고려 되지 않고 있다. 넷째, 성과 측정의 관점에서 볼때 BPR 지침들은 특히 비용 절감을 위한 목표를 달성할 수 있는 지침들의 제시가 부족한 실정이다. 또한 조직환경, 조직구조, 조직문화와 같은 조직의 특수한 상황에 적합한 연구가 아닌 일반적인 지침들만을 제시하고 있어 BPR을 추진하는 조직 및 기업에 서 그 지침들의 효과가 매우 제한된다.
