Naval Ships have a number of requirements related to performance. Naval ship acquisition takes a long time from initial planning to delivery, and various products such as drawings and reports are created. In complex systems, such as naval ships, it is difficult to maintain the required traceability through these outputs. The basic design of the ship is an important step to determine the specifications, performance, and equipment of the ship. It is necessary to apply the systematic requirements management process. The basic design manages the requirements in accordance with the systems engineering-based technical review process, but the actual system architecture design process is not presented. The traceability between the requirements and the functional and physical architectures of components is unclear. This paper examined how to design the system architecture required for specification and system design, and the design results were verified using SE-based technical review process for requirements management. A step-by-step process for designing a submarine system architecture is presented and verified using the SE technical review. This facilitates the specification of the requirements and system architecture design, and supports traceability management and verification of the requirements. The proposed process can be applied in various ships including submarines.

In general, user requirements in web-based learning systems are divided into functional and non-functional requirements. Developers are responsible for the verification of quality related requirements, which is known to be difficult to perform. This paper suggests a verification method that can be applied in the area where the conformance of implementation for non-functional requirements is required. The paper performs tests for non-functional requirements by using the information extracted from quality related features that have imposed constraints on design activities.

The purpose of this study was to find out various problem behaviors of children who were not diagnosed with any disability, but instead, engaged in problem behaviors. This study also intended to review the difficulties of children with problem behaviors, their teachers' difficulties and needs, to suggest support for child care and education teachers. This study conducted semi-structured qualitative interviews with eight child care and education teachers. The interviews were transcribed into text and analyzed by contents. The results of this study are as follows. Problem behaviors of children described by teachers were classified into external and internal types. In addition, children with problem behaviors had experienced difficulties in maintaining relationships with their teachers, peers and parents. Many teachers were not successful to provide appropriate support for preschoolers who demonstrated problem behaviors in classrooms or some teachers provided individualized support. Teachers adapted the behavioral and the psychological approaches to problem behaviors of preschoolers. However, teachers reported difficulties with children with problem behavior and brought up the following issues on teaching children with problem behaviors; managing troubled matters happening in the class, difficulty in controlling teacher's emotions on problem behaviors, the lack of time, the integrated child care time without teacher in charge of child, the interruption in activity progress, the lack of a special way to deal with problem behaviors, and difficulty in cooperation with families through parents-teacher counseling sessions. Teachers counseled with parents who had a child with problem behaviors and revealed that parents reacted to problem behaviors in various ways such as embarrassment, acceptance, ignorance, or avoidance. Most teachers received assistance and support for teaching children with problem behaviors, from families, local communities and in-service training. Lastly, teachers with preschoolers with problem behaviors needed the support of experts on managing behavior problems, assistant teaching personnel, education for parents and teachers, respects for teachers, psychological counseling or play therapy from professional service agencies, diagnosis service at child care and education centers which children attended, and support networking with agencies. Teachers also required the family support of medical diagnosis and psychological counseling and financial support from the government.

The purpose of this study is to try to structuralize the perception of the mothers of science-gifted elementary students using the concept mapping approach. The mothers who participated in this research had children who were 5th and 6th graders selected as science-gifted by a regional education office, a science high school and two national universities in a city. One of the authors interviewed 26 mothers, and extracted 50 general statements of their perceptions about the career path of their children. Ten mothers who participated in interviews sorted a shuffled pack of statement cards. The categorization of the statements into the dissimilarity matrix was carried out by SPSS multidimensional scaling analysis and hierarchical cluster analysis to generate a conceptual diagram. After that 140 mothers rated each statement using a Likert-type response scale from one to five. The result showed six clusters of parental views such as were 'Burden of private education, grades and going to the next grade,' 'Thinking about career guidance in gifted education and school,' 'Parental roles in child career education,' 'Difficulties in career guidance at home,' 'Demand for strengthening the parental capacity for career guidance,' and 'Demand for social support.' 'Demand for social support' obtained the highest sympathy from mothers of elementary science gifted.

This purpose of this study is to identify and conceptualize difficulty of abstract experiencing human rights process conducted in caretaker workers of the disabled residential facilities by utilizing multidimensional scaling. Focused on the caretaker workers of the disabled residential facilities in Busan, gathering a declarative sentence from caretaker workers, have classified index card. According to the results of the analysis, be reached name of six cluster. In facilities, caretaker workers was recognized Communication of the conflict between those People with intellectual disabilities, intention of service provider is not taken into account, those people emphasis to show up for caretaker workers, conflict based subjective human rights awareness of those People with intellectual disabilities. External facilities, interest in human rights is increasing becoming of pollution have difficulty to work hard time gaps between practice of human rights management and on-the-job experience, the rigidity of human rights investigation and inspection, lack of consideration for the caretaker workers. Based on this result, this study suggested a number of practical implications which can be used to reduce difficulty of human rights process conducted in the caretaker workers of the disabled residential facilities.

High-rise residential buildings these days tend to adopt a building frame system as primary earthquake resisting structural system for some architectural reasons. But there exist several ambiguities in designing such building frame systems according to current codes with regards to : the effective stiffness property of RC cracked section in static and dynamic analyses, analytical model to evaluate story drift ratio, and deformation compatibility requirements of frames. The comparative study for these issues by appling KBC 2005 to a typical building frame system shows that demands of member strength and story drift ratio can be different significantly depending on engineer's Interpretation and application of code requirements. And a building frame system can be noneconomical, compared with the dual system, because of higher demands on strength or ductility in both frames and shear walls.

Synthesis 기술은 요구사항을 입력 받아서 자동적으로 시스템을 생성한다. 그러므로 생성된 시스템에 대한 추가적인 테스팅과 검증을 요구하지 않는다는 장점이 있지만 자연어가 아닌 특별한 형태의 논리식으로 요구사항을 기술하기 때문에 정확하게 변환되었는지, 누락된 요구사항이 있는지 확인하는 과정이 반드시 필요하다. 이러한 Synthesis 기술을 로봇 계획 분야에 적용하면 다중 로봇의 작업 계획도 단일 로봇과 동일한 형태로 확장하는 것이 가능하다. 그러나 기존의 LTLMoP 시뮬레이터는 단일 로봇의 시뮬레이션만을 지원해서 다중 로봇의 시뮬레이션은 어려움이 많았다. 따라서 본 연구에서는 다중 로봇들의 작업 계획도 시뮬레이션 할 수 있도록 LTLMoP 시뮬레이터를 확장하였고 사례연구를 통하여 이를 확인하였다.
