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.

SPI (Software Process Improvement) activities have been considered one of the crucial approaches to achieve high quality, productivity and timely delivery of software products and services. The basic premise of SPI model is that higher maturity levels lead to better performance. In this research, the relationships between SPI results and performance were empirically investigated with Korean software companies. CMM key process areas were categorized into two dimensions, "Process Implementation" and "Quantitative Management". The relationship between process implementation and performance was significant, but the relationship between quantitative management and performance was insignificant. The control variable, size of OU(Organizational Unit), did not have significant impact on the relationships between SPI activities and OU performance.

본 논문은 소프트웨어를 재사용하기 위한 클래스 라이브러리 관리 시스템(CLMS: Class Library Management System)을 설계하고 구현에 관한 것이다. 통신 관련 소프트웨어의 특징은 소프트웨어가 방대하고, 다른 소프트웨어와 달리 개발이 완료되어도 끊임없이새로운 서비스를 수용해야 하며 개발 후 유지보수 및 신규 서비스의 확장 및 추가가 용이해야 한다는 것이다. 이러한 특징 때문에 소프트웨어 재사용은 생산성과 품질 향상에 기여할것이다. 클래스 라이브러리 관리 시스템은 객체지향 데이타베이스를 기반으로 클래스 등록기, 클래스 검색기, 클래스 항해기로 이루어져 있으며 원시 코드뿐만 아니라 SDL 설계 명세서도 재사용 할 수 있도록 고안되었다.

As WSNs(Wireless Sensor Networks) are being deployed widely in diverse application areas, their management and maintenance become more important. Recent sensor node software takes modular software architectures in pursuit of flexible software management and energy efficient reprogramming. To realize an flexible and efficient modular architecture particularly on resource constrained mote-class sensor nodes that are implemented with MCUs(Micro-Controller Units) of a single address space. an appropriate module linking model is essential to resolve and bind the inter-module global symbols. This paper identifies a design space of module linking model and respectively their implementation frameworks. We then establish a taxonomy for module linking models by exploring the design space of module linking models. Finally, we suggest an implementation framework respectively for each module linking model in the taxonomy. We expect that this work lays the foundations for systematic innovation toward more flexible and efficient modular software architectures for WSNs.

For the implementation of callcontrol software, it will be shown how to divide problems into dimain and also presents methodologies to specify domains according to the object-orented analysis techniques. Domains is specified by the set of related objects as shown in call control examples. Events and conditons are able to be transformed into system invariant so that is possible to figure out the relationship between domains and those concludes that the software requirements specification can be established for the design and implementation. Relationships existing between domains can be formalized so as to verify software requirements.

Monitoring system is essential part in control system to monitor the circumstances of the industrial equipments. Color graphics is generally introduced in the monitoring system for the purpose of effective human interfaces. Hence, color graphic editor is under the implementation to draw graphic elements easily which are utilized in the monitoring situation. In this study, OOP(object oriented programming) is applied in the programming of the software. OOP enables systematic design of algorithm, easy management of the software and easy extension of additional functions. It is reported that the software is under the implementation. Therefore, preliminary structure of the software is briefly discussed in this paper.

교육부는 최근 2025년부터 초중고에 인공지능교육을 도입한다고 발표하였고 언론에서는 인공지능교육 도입에 대한 우려를 나타내는 기사들을 내보내고 있다. 본 연구에서는 초등학교에서 실제 인공지능교육을 담당할 교사를 대상으로 인공지능교육 도입에 대한 인식을 분석하는데 주안점을 두고 소프트웨어와 관련된 학습경험이 많은 교사와 학습경험이 적은 교사로 구분하여 조사하였다. 분석결과, 학습경험이 많은 교사는 인공지능교육 도입에 100% 찬성의 입장을 나타내었고 학습경험이 적은 교사는 80%가 긍정적 의사를 나타내었다. 학습경험이 적은 교사의 20%가 반대하는 원인 중에는 현재의 실과 교과에 포함된 소프트웨어 단원으로도 충분하다가 높은 비율로 나타났다. 학습경험이 많은 교사와 학습경험이 적은 교사 모두 적절한 교육시기로 5-6학년을 가장 많이 선택했고 교육시수는 주당 1시간을 가장 적절한 시수로 보았다. 교과 구성 형식은 학습경험이 많은 교사의 75%가 소프트웨어교육을 독립교과로 하고 그 안에 인공지능교육을 포함시키는 방안을 선택하였고 학습경험이 적은 교사의 54%가 인공지능교육을 독립교과로 하거나 소프트웨어교육을 독립교과로 하고 인공지능교육을 그 안에 포함시키는 방안을 선택하였다. 교육내용의 선호도는 인공지능 프로그래밍 기초, 인공지능 개념 원리, 인공지능 윤리 순으로 나타났다.

In this paper, we propose efficient masking methods for ARIA and AES. In general, a masked S-box (MS) block can be constructed in different ways depending on the implementation platform, such as hardware and software. However, the other components of ARIA and AES have less impact on the implementation cost. We first propose an efficient masking structure by minimizing the number of mask corrections under the assumption that we have an MS block. Second, to make a secure and efficient MS block for ARIA and AES, we propose novel methods to solve the table size problem for the MS block in a software implementation and to reduce the cost of a masked inversion which is the main part of the MS block in the hardware implementation.
