Not only is it important that the physical properties of the paperboards be appropriate for the intended end use, but the proper arrangement of the component in the built-up board is essential for attaining the optimum moment of inertia and the maximum load-carrying ability in a box. It is known to be impossible to estimate the stress distribution and deflection pattern by experiments or theoretical analysis when the corrugated fiberboard get the bending force. This study was tried theoretical and finite element analysis to analyze structural strength characteristics of corrugated fiberboards. If the linerboard and corrugating medium of every corrugated fiberboards is made from the same material, the location of neutral axis comes close to inside liner in order of DMA, DM, DMB, SW and DW, and moment of inertia of area decreases in order of DMA, DMB, DW, DM and SW. With the finite element analysis, deflection of applied loads represented SW, DM, DMA, and TW in the order of their value.

본 논문은 레거시 시스템을 새로운 시스템 환경으로의 변환 및 통합을 위한 재공학 방법론을 제시하고자 하는 것이다. 기존의 역공학 및 재공학 방법들은 주로 프로그램 소스를 정적 분석하고 유지보수 하는데 중점을 두었으나, 본 방법론은 다양한 추상화 수준에서 역공학 정보를 복구하고, 컴포넌트화 단계를 통해 새로운 시스템으로 진화할 수 있는 절차 및 기법들을 제공한다. 레거시 시스템 컴포넌트화를 위한 방법론은 변환계획 단계, 역공학 단계, 컴포넌트화 단계, 인도 단계의 4 단계로 구성되어 있으며, 본 논문에서는 각 단계에 대한 활동 및 상세 절차에 대하여 기술한다.

Recently, demands of information devices are increasing as we can find so many information devices around us such as smartphone, MID(Mobile Internet Device), Tablet. These characteristics of information devices services should support soft real-time based time guaranteed multimedia services and control internet appliances. In this situation, soft real-time supported system should be developed to consider as a total aspect of hardware, kernel, middleware, application. But this paper will describe soft real-time supporting and evaluation methods for information device as an aspect of only kernel.

Computational Thinking is one of the biggest issues in the era of the Fourth Industrial Revolution. It is a core literacy required not only for SW major but also for all students including them. It is not a simple computer software education, but a coding education based on Computational Thinking, and it should be able to solve the problems in everyday life and to express the process and solutions. However, in the case of students who lack background knowledge on SW and programming languages for development, it is hard to know how to algorithmize problems and express them using computer devices. In this study, we proposed a education course model to improve the students' thinking skills and to express them effectively. In addition, we confirmed whether the non-major students who learned through this education course model can express various problems related to the major field by integrating them with computing accidents and improve the problem solving ability.

As technology has developed, companies in Korea change the object which improve the quality of product to meet customer satisfaction not to produce products more. While companies are trying to follow the international standard for quality assurance or obtain certification, outside verification and work by trusting is temporary. This research suggested organization composition and role for assuring quality of company through researching for ISO9000 and organization.

본 연구는 2015년 교육과정에 명시된 정보교과의 운영방침과 중등학교 소프트웨어 교육 현황을 분석하고, 이에 대한 문제점을 해결 할 수 있는 방안으로 창의적 문제 해결력을 통한 소프트웨어 교육 모형을 제안한다. 창의적 문제 해결력은 확산적 사고와 수렴적 사고를 통해 학생들이 문제 해결에 필요한 사고를 키울 수 있는 모형이다. 이에 본 논문에서는 컴퓨팅 사고력을 가진 창의·융합 인재 육성이라는 소프트웨어의 교육 목표를 달성하기 위해 기존의 CPS모형과 CT의 요소간의 유사점을 확인하고 이를 바탕으로 새로운 CPS-SW 모형을 제안한다. CPS-SW 모형으로 컴퓨팅 사고력과 창의적 문제해결력을 키울 수 있으며, 이를 통해 미래 사회에 필요한 인재육성을 위한 소프트웨어 교육의 발전에 기여하고자 한다. 또한 CPS-SW 모형을 적용할 수 있는 프로그램과 학생들이 창의적 문제해결력을 키울 수 있는 학습에 대한 연구가 필요할 것으로 예상한다.

MDD/MDA which recently raising its head is technology that increase software development productivity through automatic transformation form higer abstract model into lower abstract model, or from model to code. This paper analyzes the effect on productivity by measuring Function Point per MM(man-month) in a software development project which performed in CBD methodology, and introduce the method of applying MDD/MDA technology in the project.

The purpose of this study was to design a competence teaching-learning model that could help college students improve their computational thinking among core competences in SW education. A competence teaching-learning model, UDDPAAP (Unplugged-Demonstration-Decomposition-Pattern Recognition-Abstraction-Algorithm-Programming), was designed by analyzing competences of learners with no experience in software coding, by reconstructing DMM, DDD, and DPAA among the five existing SW-based teaching-learning models, and by analyzing unplugged activity and the Bebras challenge computational thinking scale carefully. The unplugged activity partially adapted to instruction for college students and some items chosen from the Bebras challenge computational thinking scale were applied to the existing teaching-learning model. To determine the effects of the study, pretest was conducted in freshmen for computational thinking and self-confidence on the basis of the experience in SW and computer information literacy education, and posttest following instruction applying the UDDPAAP teaching-learning model. The students provided with SW education based on the UDDPAAP teaching-learning model saw their computational thinking competence improved.

This study analyzes the results of a survey based on classes conducted in the field to understand the educational needs of learners, and reflects the elements necessary for SW education. In this study, various experimental elements according to learning motivation and learning achievement were constructed and designed through previous studies. As a survey applied to this study, experimental elements in three categories: Faculty Competences(FC), Learner Competences(LC), and Educational Conditions(EC) were analyzed by primary area and secondary major, respectively. As a result of analyzing CT-based SW education by area, the development of educational materials, understanding of lectures, and teaching methods showed high satisfaction, while communication with students, difficulty of lectures, and the number of students were relatively low. The results of the analysis by major were found to be more difficult and less interesting in the humanities than in the engineering field. In this study, Based on these statistical results proposes the need for non-major SW education to improve into an interesting curriculum for effective liberal arts education in the future in terms of enhancing learners' problem-solving skills.

소프트웨어 시스템 개발에 있어 요구사항 분석 단계는 개발 프로세스의 최 상위 단계로 프로젝트의 성공과 실패를 결정하는 중요한 단계이다. 특히, 반복 점증적 개발 프로세스를 적용하는 경우에 있어 고객 요구사항을 우선순위화하여 제한된 일정과 자원을 활용하여 제품을 개발하는 방법론이 필요하다. 기존 방법과 달리 본 논문에서는 SW QFD를 활용하여 고객관점 우선순위에 개발 관점을 추가하고 하위 수준 (Low Level) 요구사항까지 우선순위화 하는 Enhanced SW QFD 방법론을 제안한다. 고 품질의 소프트웨어 제품 개발을 위해 고객 요구사항을 명확하게 이해하고 고객과 개발자 양방향 관점 우선순위 프로세스를 제시한다.
