이 연구의 목적은 신뢰도와 타당도가 확보된 계절 변화 개념 검사 도구를 개발하고 계절 변화 개념과 관련된 하위 개념과 오개념에 대하여 객관적으로 관찰하고 분석하여 변인 간의 관계를 설명하고자 하였다. 계절 변화 개념 검사 도구의 개발 과정은 검사 도구 개발 계획 수립, 검사 도구 초안 개발, 예비 검사 및 검사 도구 수정, 최종 검사 도구 개발, 본 검사 실시의 과정으로 이루어졌다. 개발된 검사 도구는 학생의 계절 변화 개념 형성 정도를 검사하고 개념 형성에 어려움이 있다면 그 원인이 무엇인지 분석하여 적절한 학습과 도움을 제공하는데 활용할 수 있다. 개발한 검사 도구를 이용하여 6학년 198명을 대상으로 한 회귀 분석 결과 선수학습개념의 이해정도와 오개념의 교정 정도는 계절 변화 단원에서 학습한 개념에 정적으로 유의미한 영향을 미치는 것으로 나타났으며, 특히 오개념이 더 큰 영향을 미치는 것으로 나타났다. 평균 점수를 기준으로 절단점을 생성하여 구분한 두 구간 중 평균 점수 이상 구간 학생들은 오개념의 교정 정도가 유의미한 영향을 미쳤으며, 평균 점수 이하 구간 학생들은 선수학습개념의 이해정도가 유의미한 영향을 미쳤다.

As one of the important purpose of the concept is mutual communication, the concept should be defined clearly concerned concept, differed from others concept, identified intersubjectiveness, and could communicated readily and easily between researcher and practitioner through concept analysis. By analysing and synthesizing the concept of "Sanhujori" according to concept analysis of Walker and Avant. The author has tried to establish the term "Sanhujori" which gas been widly used from the past till now in Korea as a scholarly terminoloy and to develop a tool for the assessment of "Sanhujori". The conceptional attributes of the "Sanhujori" were figured out such as (1) hospitality; (2) physical and emotional recovery; (3) caring; (4) maternal role attainment. The assessment tool for the "Sanhujori" was constituted of 40 items of the conceptional attributes and tested on the 30 mothers more than 8 weeks of postpartal period. The reliability was that Cronbach's $\alpha$ is .9238.

This paper describes system technical requirement development process from operational concept using computer-aided Systems Engineering tool(CASysE Tool-CORE). The army tactical missile system-ATACMS's technical requirements are developed by the process as a case-study The scope of the work is context analysis and requirement definition process. The proposed process is as follows. At first, an integrated architecture could be developed from the operational concept. From the integrated architecture a capability needs, which includes KPPs, are generated. And the capability needs expanded according to the Mil-Std-961D format. Lastly, a system technical requirement could be generated automatically from the CASysE Tool-CORE.

The purpose of this study is to develop concept map as a tool of performance assessment in mathematics and to conduct feasibility test of the task. I developed and applied a concept map, an assessment tool, in the form of a mathematics performance task for 1st and 2nd year middle school students. I also conducted feasibility test of the task, and at the same time sought ways to guarantee reliability of the assessment procedure. Results of the task assessment can be summarized into the following four points. First, the concept map task was found to be appropriate for an assessment of mathematics in middle school. Second, results of all 10 factors on verification of validity of the content of the task were positive with over 50%. Third reliability of teachers who conducted marking of the four concept map tasks was high, all recording over .871 in correlation number.

In this paper, we present a 5W1H programming model for IT non-experienced people who are not familiar with computer programming and those who need programming education. Based on this model, we can design a development tool that can be easily programmed by beginners. This development tool is a programming method applying the 5W1H concept and constructs a sentence to satisfy the control condition of 'Who, When, Where, What, and How', which is the sentence element of 5W1H. Therefore, the user can easily develop the target system as if constructing the sentence without learning the programming language of the target system. In this paper, to verify the effectiveness of the 5W1H programming model proposed in this paper, we applied the concept of 5W1H programming to Arduino and developed the development tool and performed the first verification and applied the second verification to the speech recognition smart home development platform.

This study was conducted in order to inquire into the impact of children's self-concept construction and ego-development enhancement during Group Sandplay Therapy. The Group Sandplay Therapy sessions were held once week, for a total of 20 weeks. The Group Sandplay Therapy Process consisted of playing with sand and creating a sand tray in groups. There were two group in total. Each group had 4 children of the same sex aged from six to seven years old. In order to study the self-concept and ego-development, we used a self-concept test and ego-development as a research tool. In addition, the present research analyzed any changes which tool place by dividing each aspect in each sand tray of the therapy process into a positive subject and a negative subject, and analyzed the changing patterns seen in the sand tray worldas it unfolded. It was proven that an efficient treatment in changing the sand tray world and children's action, had an effect on rearranging the children's mental schemas. In terms of the progress of the sandplay journey, it was seen that negative elements decreased dramatically and positive elements were observed to have increased. As a result it was confirmed that Group Sandplay Therapy had a number of positive effects in the construction of children's self-concept and in terms of the enhancement of children ego-development.
