  • This paper presents the development of specialized software for annotating volume-of-interest on 18F-FDG PET/CT images with the goal of facilitating the studies and diagnosis of head and neck cancer (HNC). To achieve an efficient annotation process, we employed the SE-Norm-Residual Layer-based U-Net model. This model exhibited outstanding proficiency to segment cancerous regions within 18F-FDG PET/CT scans of HNC cases. Manual annotation function was also integrated, allowing researchers and clinicians to validate and refine annotations based on dataset characteristics. Workspace has a display with fusion of both PET and CT images, providing enhance user convenience through simultaneous visualization. The performance of deeplearning model was validated using a Hecktor 2021 dataset, and subsequently developed semi-automatic annotation functionalities. We began by performing image preprocessing including resampling, normalization, and co-registration, followed by an evaluation of the deep learning model performance. This model was integrated into the software, serving as an initial automatic segmentation step. Users can manually refine pre-segmented regions to correct false positives and false negatives. Annotation images are subsequently saved along with their corresponding 18F-FDG PET/CT fusion images, enabling their application across various domains. In this study, we developed a semi-automatic annotation software designed for efficiently generating annotated lesion images, with applications in HNC research and diagnosis. The findings indicated that this software surpasses conventional tools, particularly in the context of HNC-specific annotation with 18F-FDG PET/CT data. Consequently, developed software offers a robust solution for producing annotated datasets, driving advances in the studies and diagnosis of HNC.

  • Since the concept of software engineering was first used in 1968 by NATO Science Committee, a lot of research work and improvements have been made on software development methodology and software quality control, but they still fall short of ensuring successful development of small and medium scale software systems. Under these circumstances, Center for Software Engineering (CSE) at National IT Industry Promotion Agency(NIPA) has been conducting studies on quality control methodologies of software visualization well-suited for small and medium scale software systems, and also working on the systemization and quantification of software quality control. In this paper, we attempt to scope on the software development management of domestic and foreign small and medium-sized enterprises that are lying in the blind spot, compared to large enterprises with well-organized software development systems. In particular, based on software visualization that CSE is pursuing for small and medium-sized developers, we propose a practical quality control methodology well-suited for small and medium scale projects, and a low-cost quality control management tool by combining open-source quality control tools. Our proposal is expected to induce developers' mind change in SI-specialized small and medium-sized software enterprises, increase their profits and improve customer satisfaction through project quality control.

  • Information technology(IT) is changing rapidly based on growth of internet and computer businesses. Therefore, computer programs and softwares are distributed to computer users promptly for their productivity increase and efficient work. So, in the distribution, the softwares will be copied or released through network or other methods which are not authorized by the program owners. In that case, copyright dispute is incurred and various issues are come out due to infringement of the software copyright. Thus, the purpose of this study is to research infringement cases of the software copyright and how to settle the dispute which is related with software programs. To achieve the purpose of this study, this research consisted of 5 chapters. At chapter 1 introduction, it mentioned necessity of this study, purpose and how to research this study, and at chapter 2 dispute factors indicated and summarized for technical resolution. At chapter 3, infringement cases of software copyright analyzed and studied upon intellectual property(IP) related laws. And methods of dispute settlement discussed and suggested to chapter 4 for copyright and intellectual property protection. Also, it emphasized importance of arbitration to resolve the issues timely and avoid time and economical consumption. Of course, arbitration law has to be matched with the trend of technology development for effective settlement. At chapter 5 conclusion, it summarized this research and suggested further research for empirical test of economic value of the software copyright upon the aspect of business, law, and engineering. In this study, the results are 1) IP related laws have to be enacted or revised to meet technical changes for the protection of software copyright on time. The enactment or the revision of law takes a long time, therefore, to deal the dispute effectively, 2) arbitration law has to be utilized efficiently in order to resolve issues and settle the dispute promptly. It is suggested the dispute settlement through arbitration to save time and economic matters for legislation, and to harmony with the technology trends. 3) Recognition of software copyright is to be improved by users and enterprises for development of software related industries and intellectual property protection. In conclusion, the protection of software copyright is important than any other things in the field of IT because of the development of industry and intellectual property related laws. The development is for areas of business, law and engineering, so research and practices are to be combined with the areas so that it could resolve the dispute settlement and IP protection effectively.

  • Recently, the rabid development of information technology has brought enormous changes in education. Consolidation of communications and multimedia technologies are enabling the new educational paradigm such as distance learning and virtual education. Furthermore, many studies in the education engineering field report that teaching using multimedia technologies more enhances students' performance than the traditional instructor-teaching method. However, little research regarding the education using multimedia has been done in the MIS filed. None of multimedia-related studies could be found in the top-ranked MIS journals published in Korea for the last five years, and only a few studies were found even worldwide. In this regard, the purpose of this study is to investigate which features of multimedia software are most important to enhance the teaching results of students. From the previous research, we found out the specific features of the educational multimedia software which are considered to affect the students'performance, and defined the research variables related to those educational software features. And, based on the constructivism and motivation theory of the education engineering field a theoretical research model and research hypotheses were developed. Perceived usefulness of the class and a student's perceived interests in the class were used as surrogate variables to measure teaching performance. Total 277 students participated separately in one of the two multimedia classes which have continued for three weeks. One was C programming language class and the other was multimedia CD-title development class. Each student listened for the multimedia session of the class using multimedia software and, at the end of the multimedia session, answered the survey questionnaire. The results of the study show that motivation to the class and the contents of education were statistically significant to the students'performance in the class. That implies, not only in the traditional instructor-teaching method but also in the multimedia class, that the contents of education itself and student's motivation to the class are most important to raise instructional results.

  • 관점지향 소프트웨어 개발방법(AOSD)은 시스템을 관심사별로 분류하고 횡단관심사를 식별하여 애스팩트 클래스로 구성함으로써 높은 유지보수성이 요구되는 사용자 중심의 시스템 설계를 위한 중요한 소프트웨어 개발방법으로 부각되고 있다. 그러나 기존의 관점지향 소프트웨어 개발방법에 대한 연구들은 횡단관심사의 식별과 명세에 대한 연구들과 애스팩트 클래스를 중심으로 하는 시스템 구현에 대한 연구들이 대부분이며, 식별된 횡단관심사의 추적 방법에 대한 연구들은 매우 미흡하였다. 따라서 본 연구에서는 AOSD를 기반으로 시스템 모델링 단계에서의 횡단관심사 추적을 위한 관점지향 슬라이싱 기법을 제안하였다. 유스 케이스들 간의 상호작용 분석을 통해 횡단관심사를 식별하여 명세한 후 식별된 횡단관심사 추적을 위한 슬라이싱 기법을 제시하였으며, 사례연구를 위해 학습관리시스템(LMS)에 이 기법을 적용하였다. LMS는 시스템 기능의 잦은 변경 및 확장 요구가 많은 사이버교육 시스템으로 이 시스템의 개발에 유지보수성을 높이는 AOSD를 적용하는 것은 매우 효과적인 방법이다. 그리고 마지막으로 기존 연구와의 비교분석 결과를 제시하였다.
