The purpose of this study was to find the effect of intuitive free association and systematic free association on the creativity of high school students group in the conceptual design process. Based on this study result, the conclusion can be summarized as follows. 1. There was meaningful relation between intuitive free association and creativity factor of high school students. Mean value of experimental group A 's creativity and it's factor originality, practicality, elaboration, and fluency which treated intuitive free association was increased. 2. There was meaningful relation between systematic free association and creativity factor of high school students. Mean value of experimental group B 's creativity and it's sub factors: originality, problem solving, elaboration, and fluency which was treated systematic free association was increased. 3. It was found that two different divergent thinking does not show any meaningful difference in creativities of two groups. However, the meaningful difference was found in post creativity test in each groups sub-factors. There was meaningful difference in practicality factor, though there was no meaningful difference in originality, elaboration, fluency factors. Using the obtained results, it was concluded that intuitive thinking and systematic thinking play different roles in practicality which is one of sub-factors of the creativity of high school students. Consequently, it can be concluded that systematic thinking which leads students to take a step to solve a given problem can elicit more scientific thinking, and helps students create more practical solution in problem solving than intuitive thinking that emphasize the quantitative aspect of ideas.

최근 인문사회과학은 지역적 특수성과 문화적 배경(context)를 무시하고 법측과 체계(system)을 추구하는 자연과학의 개념을 인간사회에 적용하려는 여러 이론들이 인간의 근본적인 문제를 해결하는데 한계가 있음을 지적하고 있다. 이러한 법치주의에 의한 법인간적인 해석보다는 지역적이고 문화적 상황하에서 인간사회의 문제를 이해하려는 경향이 지금까지 행태(behavior)나 사회구조(social structure system)의 이해를 통해 인간사회를 분석하고 있다. 그 방법론으로는 전체의 맥락(context)이나 주변의 연관관계를 통해 의미를 이해하는 책(text)의 해석(interpretation)의 비유를 그 틀(paradigm)로 하고 있다. 이러한 경향은 예술과 미의 문제도 같은 체계(system)속에서 이해하여 현대의 전통, 문화와 대중으로부터 분리된 예술과 미로부터 전통, 문화, 개인과 생활이 공명할 수 있는 본래의 예술과 미를 찾으려 한다. 본 연구는 이러한 사회문화 이론의 개념을 분석하고 그 원리와 이론의 축면에서 경관(landscape)을 해석하고 경관의 의미(미를 포함한)체계(meaning system)을 분석하여 설계언어(design language)를 찾아내며 이를 설계에 응용할 수 있게 하는 기본적 틀(paradigm)을 제시하고자 한다.

Teachers often encounter challenges in supporting students with question generation and the development of investigation plans in sensemaking activities. A primary challenge stems from the ambiguity surrounding how students apply their conceptual understandings in this process. This study aims to explore how students apply their conceptual understandings to generate questions and design investigation processes in a sensemaking activity. Two types of student group activities were identified and examined for comparison: One focused on designing a process to achieve the goal of sensemaking, and the other focused on following the step-by-step scientific inquiry procedures. The design of investigation process in each group was concretized with epistemic criteria used for evaluating the designs. The students' use of conceptual understandings in discussions around each was then examined. The findings reveal three epistemic criteria employed in generating questions and designing investigation processes. First, the students examined the interestingness of natural phenomena, using their conceptual understandings of the structure and function of entities within natural phenomena to identify a target phenomenon. This process involved verifying their existing knowledge to determine the need for new understanding. The second criterion was the feasibility of investigating specific variables with the given resources. Here, the students relied on their conceptual understandings of the structure and function of entities corresponding to each variable to assess whether each variable could be investigated. The third epistemic criterion involved examining whether the factors of target phenomena expressed in everyday terms could be translated into observable variables capable of explaining the phenomena. Conceptual understandings related to the function of entities were used to translate everyday expressions into observable variables and vice versa. The students' conceptual understanding of a comprehensive mechanism was used to connect the elements of the phenomenon and use the elements as potential factors to explain the target phenomenon. In the case where the students focused on carrying out step-by-step procedures, data collection feasibility was the sole epistemic criterion guiding the design. This study contributes to elucidating how the process of a sensemaking activity can be developed in the science classroom and developing conceptual supports for designing sensemaking activities that align with students' perspectives.

한국형 원자로를 개량, 2001년부터 건설될 제2세대 원자로의 뒤를 이을 제3세대 원자로인 한국형 신형 원자로 CT-1300의 개념 설계가 최근 마무리되었다. CT-1300은 혁신적인 피동 설계 개념을 이용하여 안전도를 대폭 향상시킨 원자로이다. 즉 무거운 것은 아래로 내려가고 가벼운 것은 위로 올라간다는 불변의 자연법칙을 이용하여 각종 안전 장치를 설계함으로써 , 설령 지진이나 폭격 등의 원인으로 발전소에 이상이 생길지라도 안전 장치가 운전원이나 전기 장치의 도움 없이 작동할 수 있도록 한다는 것이다. 피동 설계 개념은 발전소의 안전성 향상 뿐만 아니라 경제성에도 크게 기여할 것으로 기대된다.

본딩은 전기/전자 시스템뿐만 아니라 연료, 엔진, 비행제어, 유/공압계통 등에서도 안전한 전기적인 운용을 하기 위해서 필요하다. 항공기 개발에서 본딩은 설계시부터 요구조건을 두어 엄격히 관리해야 하며, 제작시에도 제시된 요구조건에 맞게 본딩을 해야 한다. 항공기의 전기/전자계통 설계시 요구성능과 항공기 및 운용자의 안전성 확보를 본딩 계통의 설계목표로 설정하고, 세부적인 본딩 요구조건과 유사기종의 설계개념을 보완하여 현실적으로 적용가능한 적용분야별 본딩 설치 및 설계 요구조건을 정립하는 것이 매우 필수적이라고 판단된다. 이 글에서는 항공기 설계시 고려해야 되는 본딩 일반요구조건에 대하여 기술해 보고자 한다.

A vocabulary for a understanding bridge has a different scope. The main characteristics of the modem footbridge are appropriateness, aesthetics and structural efficiency. Design concepts of footbridge design are investigated. There are functional concepts, aesthetical concepts like geometry, symbolism, lighting, and movement, and technical concepts. Futhermore, adaptation examples of these structural concepts for pedestrian bridges are presented.

Fallout ash is a notorious hazard that can have a variety of damages on agriculture and infrastructure and, most notably to aviation and human health. This study discusses the design of a conceptual model to aid in modeling the dispersal and deposition of ash from Mt. Baekdu volcano. It includes a discussion of assumptions and boundary conditions of the model as well as a detailed diagram of the conceptual model, complete with input parameters, units and equations. The two main processes contained within the model are the dispersal and deposition of ash, the outputs obtained from running the model, if designed, would be the total amount of fine ash contained in the eruption column, distance travelled by ash and ash thickness at surface.

The Integration of biological databases is critically important because of the interconnectedness of biological research. But it's not easy to integrate these databases for the different formats and designers in heterogeneous environments. So initial design is indispensable to integrate heterogeneous databases. In this paper, after we performed conceptual modeling on a popular nucleotide database, GenBank and a protein database, Swiss-Prot and integrated them by considering cross-reference. we also propose the integration system architecture called Bio-Gateway System, which can help users query closely linked information between two biological databases within one system differently from existing systems as well as query easily on condition that user knows fine condition for less effort.

This paper presents an analysis of the design hypothesis of integration of parts from the viewpoint of axiomatic design. In parts integration, parts with the same functions are integrated into a single part. For the analysis, a motor actuator of an outside rear-view mirror with the type of an uncoupled design was used. The parts within the actuator are checked for determining the possibility of integration, by adopting the design hypothesis of integration of parts. The design hypothesis of integration of parts is based on a type of coupled design. However, the type of incomplete coupled design that resembles the type of an uncoupled design would be better than the type of a coupled design.
