인지적으로 안내된 교수(CGI)는 학생들의 수학적 사고(특히, 비형식적 지식)의 발달; 그러한 발달에 영향을 미치는 교수; 교수 실제에 영향을 미치는 교사의 지식과 신념들; 교사의 지식, 신념들, 실제들이 학생들의 수학적 사고에 대한 이해에 의해 영향을 받는다는 점에 초점을 둔 통합된 연구 프로그램이다. 본 논문에서는 아동의 비형식적인 지식을 중시하는 최근의 연구들을 고찰하고, CGI를 위한 수업을 어떻게 조직하며, 그러한 교수법이 수업을 어떻게 진행할 것인지에 대한 구체적이고 명확한 지침을 제공하지 않으므로 CGI를 적용하는 교실들의 유사점을 살펴본다. 그리고, 마지막으로 최근의 연구들을 고찰함으로써 CGI의 효과를 알아본다.

대학수학에서 수학적귀납법의 원리를 소개하고 풍부한 예를 통해 이해를 돕는다. 특별히 교양수학을 수강하는 1학년 학생 수준에 맞게 매스매티카 프로그램을 이용하여 구체적인 예를 갖고 한단계 한단계 접근하여 수학적귀납법의 증명을 연습할 기회를 준다. 증명을 단계적으로 하는 것을 연습하여 학생들은 논리적인 사고능력을 개발하고 새로운 명제를 발견할 수 있는 기회를 맞보게 한다. 물론, 증명 연습은 1학년 신입생에게는 쉽지 않으나 여러 명제에 대해 연습을 하는 것은 수학적, 논리적 사고 능력을 개발하고 증명문제에 대한 인식을 바꾸는데 매우 중요한 역할을 할 것이다.

대한민국은 우수한 기술력을 바탕으로 한 각종 플랜트 산업이 주력업종인 강국이다. 이러한 특성에 맞게 각 산업단지에서는 고중량 대형화물에 대한 운송수요가 꾸준히 발생하고 있는 추세이다. 대형화물의 운송량이 증가할수록 고정결박 불량에 의한 화물 낙하, 이탈로 인한 차량파손, 도로파손 등의 사고가 지속적으로 발생하고 있으며, 이러한 사고의 발생 가능성은 항상 내재하고 있다. 하지만 현행 도로교통법에는 화물적재 및 고정에 대한 구체적 규정이 전무하여 화물운전자가 책임을 부담하고 있는 실정이다. 본 연구에서는 기존 화물적재 규정을 살펴보고 적합한 고정결박 지침을 제정하고 관리하는 절차의 지정을 제안하였다.

Purpose: The purpose is to prevent accidents by predicting disasters through the analysis of near-miss. Method: In this study, a near-miss literature review and data were collected at construction sites, and a questionnaire survey was conducted to use logistic regression analysis and decision tree analysis to classify the possibility of near-miss connection. Result: As a result of analyzing the effects of near-miss types on mental, physical, and safety habits and behaviors, the factor with a high influence on the body is the need for near-miss management, the type of job is electricity·information communication, and health status in order, and the mental factor is the construction scale The influence was high, and the factors with the highest influence on the habit behavior factors were analyzed in the order of experience, number of serious injuries, and occupation in order of illusion, inappropriate work instructions, and body parts. Through decision tree analysis, factors and patterns that affect the possibility of a near-miss being a surprise accident were identified. Conclusion: Construction site officials consider the observation of near-miss and mentally and physically. Specific management of the relevance of physical aspects to near-miss should be implemented, and a work environment in which serious accidents are reduced is expected through personnel allocation, work plans, work procedures and methods, and feedback so that inappropriate work instructions do not lead to near-miss.

This paper focuses on the idea development as a creative thinking process for design innovation. The process of thinking has the thinking structures of abduction and transformation. After we had studied the design thought, we found a structure of a thinking system, and created a creative thinking model with this. Using job analysis, we examined the duster of design jobs, which form the design process, and verified the thinking model. The findings suggest that our idea development has the creative process not only of divergent thinking and convergent one, but also of transformation in design. In same time, the design thinking shows their pattern of transition from abstract concept to concrete object. Between the design jobs, idea development shows higher difficulty than other jobs - marketing, product planning and follow-up. Combining the D-T-C (Divergent-Transformation-Convergent) thinking with abstract-concrete thinking, we designed a DFD(data flow diagram) for an early model of computer mediated thinking system (CMTS). This has implications for design support.

해양사고 예방을 위해서는 과학적이고 체계적인 해양사고 분석과 평가 및 예측이 우선 필요하다. 이 논문에서는 기존에 연구 개발된 다양한 해양사고 분석과 평가 방법을 검토하였다. 연구결과, 구체적이고 실행 가능한 연구접근 방법과 다양한 분석과 평가기법이 개발되어 있음을 알았다. 특히, IMO의 공식안전성평가(FSA) 절차가 세계적으로 표준화된 규준으로 자리매김하고 있다. 특히, 미국의 유명한 선급 ABS와 노르웨이의 선급 DNV에서 다양한 분석과 평가기법을 보고하였다. 특히, 불확실성이 배제된 위기허용기준(Risk Acceptance Criteria)의 개발이 가장 중요한 요소임을 확인하였다. 향후 해양사고 예방에 적용할 수 있는 고도의 분석과 평가 기법 실용화를 지속 연구할 예정이다.

The purpose of forecasting the traffic accident is to reduce the traffic accident. Therefore, the goal of this study is to provide severity of the accident by Forecasting of Probability of Accident. In Korea, accident data are distributed to the public via internet that includes numbers of accident and fatality as well. And crude level of accident severity in accordance with weather information for metropolitan city level are available by weekly. However, It can not reflect personal needs at specific origin of the travel for a certain traveller. This study aims to consider 68 major intersections with precipitation data, and eventually introduces link based accident severity. In estimating the accident severity both dynamic data such as drivers' characteristics, driving conditions and static data such as geometry of road, intersection characteristics are considered. Also, we identifies accident severity according to the accident type - 'vehicle to vehicle,' 'vehicle to person.' Finally, the outcomes of this study suggests taylor-made accident severity information for a specific traveller for a certain route.

In accordance with the changing of society, remarkable increase in knowledge and information, the competencies to choose and use proper information in various domains are considered as an important skill. As one of the methods in developing these competencies, it is emphasized that a problem-based learning can make student understand and use knowledge by solving the contextualized problem. However, it is skeptical of learner's development of competencies to use knowledge by solving well-defined given problem. Therefore it is required that students be allowed to develop the competency to find problem through experiences to determine and evaluate the purpose of the problem and method. The purpose of this study is to understand how undergraduate students use science or technology in finding a problem. In this line, this study articulated four cases conducted by participants who engaged in convergence teaching-learning program. And this study investigated the participants' process of problem-finding, method and reason to apply science or technology. The results were drawn by analyzing interviews and written data, including their proposal, a poster, and final reports. Participants changed the form of problem from initial ill-structured one into a concrete one, where the participant could derive a detailed solution. Science or technology applied as the detailed example to convert problem into a concrete form, or as the analyzing tool or theoretical background of problem to make a link with other domain. Their reason of applying science or technology could be summarized in 'personal interest based on prior experience' and 'alternatives to resolve a dissatisfaction.' Based on the result, this study suggests holistic approach that is included in both intuitive thinking and logical thinking and metacognitive regulation to stimulate problem-finding in problem-based learning program.

The purpose of this study was to analyse the possibilities and legitimacies for using integrated essay on Home Economics Education, and to suggest the instructional design. Integrated Essay consisted with three composers, subject(students), object(texts), and strategy(thinking abilities). The results of theoretical analysis, socio-constructionalism by Vygotsky, the deconstructional literacy criticism by Derrida, and cognitive psychological approach by Beyer, Wood et al, Hayes were supported the integrated essay in instruction for Home Economics Education. Also, essay tests types of university entrance exams in Korea, previous researches of thinking ability in Home Economics Education, and essay questions in textbook were analysed. As results, theoretical framework, instruction process, and instruction design for integrated essay in Home Economics Education were developed. The possibility of integrated essay is high but it's real estimate will success when Home Economics Education realize it's nature.

디자인은 일반적으로 목적지향의 창의적인 문제해결 과정으로 볼 수 있으며, 그 결과로 구체적인 대상이 세상에 존재하게 되는 것이다. 즉 무형적인 컨셉트를 가시적인 대상으로 전환시키는 산업 디자인분야에서 시각심상의 표현을 통한 조형성과 창의성은 디자이너의 중요한 소양중의 하나가 된다. (중략)
