The study tries to differentiate the levels of mathematical reasoning from inductive reasoning to formal reasoning for teaching gradually. Because the formal point of view without the relation to objects has limitations in the creation of a new knowledge, our mathematics education needs consider the such characteristics. We propose an intuitive level of proof related in concrete operations and perceptual experiences as an intermediating step between inductive and formal reasoning. The key activity of the intuitive level is having insight on the generality of reasoning. The details of the process should pursuit the direction for going away from objects and near to formal reasoning. We need teach the mathematical reasoning gradually according to the appropriate level of reasoning more differentiated.

우리나라에서 학문분야별로 출판된 전문용어사전의 표제어 기술형식은 매우 상이하다. 이러한 특징은 여러 분야의 전문용어사전을 참조해야 하는 이용자에게 많은 불편을 초래할 뿐만 아니라 표준화된 전자사전에 대한 요구를 충족시키지도 어렵다. 본 연구에서는 전자사전 표준화의 일환인 전문용어사전의 표제어 기술형식 표준화를 위한 기초작업의 일부로서 현재까지 우리나라기서 출판된 전문 용어사전을 대상으로 표제어의 기술형식에 대하여 기술요소, 기술요소의 순서, 띄어쓰기, 다의성을 갖는 용어의 구분, 배열 등에 대하여 조사 분석하였다.

현대 디자이너는 사회로부터 다양화와 현대화에 대한 지속적인 요구를 받고 있으며, 한편으로는 자원의 유한성이라는 제한으로 인해 다양화와 현대화와의 모순이라는 현실에 직면하고 있다. 이러한 배경들로 말미암아 재활용품 개발은 현대 디자인에서 중요한 분야로 자리 잡고 있다. 본 연구는 폐기물 재활용품의 모듈형식 디자인에 관한 분석을 통하여 지속 가능한 각도에서의 모듈형식 디자인의 역할과 그 중요성의 의미를 인정하고 모듈형식의 생활용품 디자인에서 나타난 정보를 통하여 재활용품 디자인의 개발방향을 제시하였다.

The form-resistant Systems like a dome and shell are used more widely than post-beam structure system in large space structure. Single layer latticed dome system, one of the form-resistant system, has great merits in manufacturing and constructing but the failure mechanism is not clarified yet. The purpose of this paper is to find out the buckling characteristics of single-layer latticed domes with square network by using the experimental method. Major test parameters are the stiffness of lattice member and space of square lattice. The specimens are applied uniform loading of snow type.

New Product Development (NPD) is essential for companies' survival, and continuous growth in the rapidly changing, convergence and business environment, and companies need to collaborate with their internal and external partners to improve performance in NPD. This research examined the integrated relationship between NPD (Cross-functional collaboration, and supplier collaboration) and collaborative communication (formality and reciprocal feedback) on corporate performance. The employees who worked in manufacturing for more than one year with experience in NPD were tested. The reliability and feasibility were assessed using the sample 272 data. The results are summarized as follows. First, cross-functional collaboration and supplier collaboration, which are the factors of NPD collaboration, had a significant positive effect on formality. Second, formality and reciprocal feedback had a significant positive effect on reciprocal feedback and corporate performance. Therefore, for successful NPD, manufacturing companies need to establish efficient management strategies and communicate officially and reciprocally to maximize productivity and efficiency based on the reciprocal partnership between suppliers. To accomplish this, companies need to plan effective communication strategies to respond quickly to internal and external partners' needs.

This study discusses the aspects of Korean-American Sjjo writers' consciousness of sijo and its significance, focusing primarily on the Sijo-Anthologies of Korean-American authors, "The Moon of the Desert" (1989), "The Dandelion of the Desert" (1994), and The Stars of the Desert" (1996) published by the Sijo Society of America. For this purpose, I thoroughly examined "Notes of Writing Sijo' attached to the authors' works and some other sijos added at the end of the paper. They started writing sijos quite early. Sijo has been recognized as a typical traditional genre of literature, and even foreigners came to write them in English. The following is the summary of the view on sijo propounded by Korean-American authors. Firstly, they follow traditional view on the theory of sijo in terms of its nature and utility, and at the same time they emphasize the utility of katharsis through self expressions. Secondly, their recognition of the value of sijo boils down to its formal patterns. Lastly, they develop the idea of national literature through their significance of writing sijos. They think that they can contribute to the development of national literature as well as the expression of patriotism through writing sijos. Therefore, they recognize themselves as spreaders of Korean culture to the local residents, and as the main stream enhancing the status of Korean culture through the competition with other nations.

우리나라가 조달하는 ITER(국제핵융합시험로) 초전도자석 전원장치용 변압기는 CCU/L(Correction Coil Upper/Lower) 컨버터 형식용 6대, CCS(Correction Coil Side) 컨버터 형식용 3대, VS1(Vertical Stabilization 1) 컨버터 형식용 2대, CS(Central Solenoid) 컨버터 형식용 6대 그리고 TF(Toroidal Field) 컨버터 형식용 1대로 구성되어 있다. ITER한국사업단은 (주)효성과 컨버터 변압기의 공급계약을 2011년에 체결하고 예비 설계를 시작하여 2014년에 최종설계를 마친 후 동년 후반부터 CCU/L, CCS 및 VS1 컨버터 형식용 각 1대씩의 초도품 변압기 제작에 착수하였다. 각 변압기는 제작이 완료되어 CCU/L 및 CCS 형식은 FAT(Factory Acceptance Test)를 완료하였고 VS1 형식은 공장 자체시험을 완료하고 현재 전기연구원에서 실시할 단락시험을 준비하고 있다. 이어 CS 형식의 초도품과 1대만 조달하는 TF 형식의 제작을 착수할 예정이고, 각 형식별 초도품 1대씩은 단락시험을 포함하는 형식시험(Type Test)을 실시하여 형식별 적합성을 검증하고, 나머지 물량은 정기시험(Routine Test)을 실시한 후 2017년까지 두 번으로 나누어 프랑스 남부에 위치한 ITER 현장에 운송 및 설치할 예정이다. 설치를 마친 변압기들은 각각의 컨버터 짝과 통합시험을 포함하는 SAT(Site Acceptance Teat)를 거친 후 ITER 기구에 인계될 예정이다.

To specify a formal semantics is to do a significant part for design, standardization and translation of programming languages. The existing studies of a formal semantics for Java have a weak point to describe a clear and practical semantics for an efficient translation. It is necessary to do research for a formal semantics to specify a static and dynamic semantics clearly in order to do an efficient translation. This paper presents the improved Action Equation that specifies a formal semantics for Java to extend the research using Action Equation. The Action Equation is a practical and accurate specification that describes object-oriented programming features and handles exceptions. The specified Action Equation is compared to other descriptions, in terms of readability, modularity, extensibility, and flexibility and then we verified that Action Equation is superior to other formal semantics.

CGI not only performed a crucial role to make cinema and animation evolved into digital cinema and digital animation but also CGI, an important visual format, settled realism-centric spectacle image culture in public commercial cinema and animation. The fact that CGI visual format could be structuralized in three different view points is discovered through Iconicity, photorealism, verisimilitude, uncanny valley, hyperrealism, and spectacular realism discourse research which explain image culture. First, a formative viewpoint that comes up in an iconic difference between drawing and photograph. Secondly, a cognitive viewpoint that sees visually perceived naturalness and abnormality as a realistic probability issue. Lastly, a customary viewpoint which is rooted in aesthetic tradition of cinema and animation. After that, the features of CGI which is used in the movie 'jungle book'(2016) were analyzed using the structured visual format. Consequently, this movie has hyper-realistic photographic iconicity on the base of realistic probability. Also, by following image-aesthetic convention which uses overstated and amplified narrative as a visual format, at the same time, the movie also has sufficient image-aesthetic convention in animation by personified animal character.
