원격 조정식 비익체(이하 RPV : Remoteloted Vehicle)의 안정성을 향상시키고 조정을 간략화하기 위하여 사용되고있는 관성센서에 관해서 알아본다. 관성센서의 기본 원리는 뉴톤의 운동 제3 법칙인 관성의 법칙이고, 특징은 외부 측정기준을 필요로 하지 않은 점에 있으므로, 관성센서를 탐재한 RPV는 공중에서 운동 상태를 외부의 정보 없이 검토할 수 있다. 실제적으로 기계용으로 실용화되고 있는 센서는 관성항법장치(INS:Inertial Navigation System)라고 불리워지는 매우 고급자립형 장치로부터 자이로 컴파스로 불리워지는 방위 자이로와 자기 방위 센서를 조합한 방법까지 여러 가지가 있지만, 여기에서는 산업용 소형 RPV의 크기, 가격 및 입수성에서 이용이 가능하다고 생각되는 센서를 중심으로 원리, 종류 및 응용예를 설명한다.

This study suggests new interpretation about ancient mathematician Archimedes' 'method'. For this, we examined the core issue related to the interpretation of the 'method' and identified the unclear relation between the principle of the lever and the indivisibles, both of which have consisted of the main point of arguments. And by having conducted the exploratory historical guesswork about Archimedes' careful use of indivisibles, we make a hypothesis that the role of the principle of the lever in Archimedes' 'method' should be the control of ratio of change.

As people get to aware that the traditional teacher-centered education can not develop individual students' diversity and creativity and cope with the rapidly changing future society, Korean government has emphasized the learner-centered education since the 7th curriculum. Under this background, we have analyzed the problems of mathematics education that teachers recognized and the features of mathematics textbooks that they developed within the framework of leaner-centered education on the basis of the resources developed from 'Student-centered mathematics textbook improvement teacher research group in 2015.' As a result of using the framework of 'Learner-centered psychological principles (APA, 1997)' for analysis, teachers pointed out the problems related to the principles of Motivational and emotional influences on learning, Individual differences in learning, Developmental influences on learning, Nature of the learning process, and Construction of knowledge, in order. The features of textbook teachers developed reflected the principles of Nature of the learning process, Construction of knowledge, and Motivational and emotional influences on learning, in order. Finally, as we have compared teachers' recognition of the problems with the features of the textbooks developed, most of the problems teachers recognized are reflected in the textbooks; however, the Cognitive and metacognitive factor takes higher possession on the textbooks compared with the problems being recognized, and the Motivational and affective factor takes lower possession on the textbooks compared with the problems being recognized. Accordingly, we have been able to search for the solution to realize the learner-centered education through math textbooks.

로봇의 중요성이 강조됨에 따라 2019년부터 초등 실과 교과에 로봇 교육이 포함된다. 그러나 일부 초등학교에서 현행되고 있는 로봇 교육은 학습자가 완성된 형태의 로봇을 조작하는 데 그친다는 점에서 구성주의 학습원리에 어긋난다. 구성주의 학습원리에 따르면 학습자는 각자에게 의미 있는 독창적인 모델을 중심으로 자신만의 세계를 만들고 그 속에서 지식을 구성해 나가야만 진정한 학습이 일어난다고 할 수 있다. 본 연구에서는 구성주의 학습원리에 기반한 초등 로봇 교육의 도구로서 WeDo 2.0을 소개하고 로봇 교육 도구로서 WeDo 2.0이 갖는 활용가능성을 탐색하였다. WeDo 2.0은 학습자에게 첫째, 자발적 학습환경, 둘째, 창의적 학습환경, 셋째, 체계적 학습환경, 넷째, 통합적 학습환경, 다섯째, 구성주의 학습환경을 제공한다. 이에 따라 향후 초등 로봇 교육에서 WeDo 2.0을 활용한 구체적인 교육 프로그램의 개발 및 적용이 필요하다.

In this study, the teaching material has been developed based on Polya's Problem Solving Techniques for preparing Korea Information Olympiad qualification and studying principle of computer. the basis of discrete mathematics and data structures were selected as the content of textbooks for students to learn computer programming principles. After the developed textbooks were applied to elementary school students of Science Gifted Education Center of J University, the result of study proves that textbook helps improve problem-solving ability using the testing tool restructured sample questions from previous test. We need guidebook and training course for teachers and realistic conditions for teaching the principles of computer.

이제 HACCP가 무엇이며 왜 이것을 단체 급식소에 적용해야 할 것인가의 것은 더 이상 논의 과제가 아니다. 문제는 어떻게 HACCP 원리를 주방 동선 구성에 적용할 것이며 동시에 이 원리 기준에 적합한 주방 기계 선정 및 운영 절차는 무엇인가에 관한 하드웨어적 접근에 관심이 모여지고 있다. 작은 정부를 주장하는 메리랜드 주에서는 미국에서 최초로 새로운 조리 시설을 짓거나 전반적 보수공사 하는 모든 외식업체는 HACCP Plan을 제출한 후 통과된 경우에 한하여 공사 허가서를 내어주고 있다. 이로써 업체 종사원 스스로가 위생 상태를 점검 기록함으로 함으로 식중독 사고를 사전에 예방함과 동시에 공무원의 업체 방문을 최소화 하여 적은 인원으로 효율적인 주 정부 운영을 하고 있는 것이다. 또한 자발적으로 많은 외식 업체들이 마케팅 차원에서 경쟁 업체와의 차별화 정책의 일환으로 스스로 서둘러 HACCP를 도입하고 있다. 워싱턴 DC지역에서는 요식협회 스스로 HACCP를 도입한 외식업소에 "Extra Step"이라는 로고를 사용케 하고 있다. 이로써 보다 많은 고객들이 이 로고를 보고 해당 식당을 선택토록 광고의 효과를 더 하기 위함이다. 당연히 이와 같은 추세에 따라 유럽과 미국의 세계적인 주방 기기 메이커들도 미국의 National Sanitation Foundation(NSF), US Dept of Agriculture(USDA) 및 FDA 의 규제 흐름에 따라 상당히 빠른 속도로 HACCP 원리에 적합한 기능을 기계적으로 보완해 가고 있다. 최근 4/15/98, FDA가 대량 급식소를 포함한 주방의 HACCP 적용매뉴얼을 인터넷 web 주소 http://vm.cfsan.fda.gov/~dms/ hret-1.htm 통하여 발표한 내용과 미 육군의 식당 위생 기술 자료 TB MED 530 자료, 그리고 87년 12월 이후 (주)HRS 에서 기계 설치 사후 관리하면서 경험한 사항을 중심으로 다음 내용을 정리해 보고자 한다.리해 보고자 한다.

Consciously or not, producers have to make many aesthetic choices in creative process of video production. If there are general acceptable aesthetic principles to make right choice it would be guideline of aesthetic decision to somewhat reduce mistakes and errors in the process. This paper proposes a theoretical approach on establishing the media aesthetic principle of 3D animation camera working, which is the most suitable for animation production context. We describe the Herbert Zettl's applied media aesthetics related directly to the camera, which is about the two-Dimensional field focusing on aspect radio and forces within the screen, three-dimensional field focusing on depth, volume, and four-dimensional field focusing on time and motion. In order to have theoretical approach we made an analysis on comparing a camera working of movie with 3D computer animation's one, and reconstructed these basic principles to be suited for the 3D animation production. When applied media aesthetics of the traditional camera working are applied to the 3D animation production, it could be an efficient guideline for it. Futhermore, if we develop the research for the relationship with various visual languages with the basis of these principles, the theory of creative picture composition method for the 3D animation production will be logically and systematically established.

Customers who visit nail shops need creative and unique designs, but at present nail artists remain at the level of design imitation, new nail art designs should be developed to satisfy customers. Therefore, this study presented convergent nail art designs using formative art principles which are the basis of all design with the aim of contributing to creative nail art designs. For this purpose, this study investigated specialized books, Internet data and previous studies on the subject, analysed concepts and cases of formative art principles, and the concept of nail art and related expressive techniques to create six convergent nail art designs. As nail art techniques, this study used hand painting, marbling, see-through, etching, embossing, patching and objet. As a result, this study presented unique and creative nail art designs using formative art principles and found the possibility of creating new nail art designs. This study has meaning in that the results of this study are significant as basic data to enhance the design capabilities of nail artists.

This study was performed to derive a new business administration framework based on the service philosophy established in the previous research. We proposed a business administration system that reflects the changes of modern economic society and solves problems of existing business administration. The problem of the existing business administration is analyzed by analyzing the essential problems of business administration as a discipline and the practical problems of current business administration. New management theory must have a status as an intrinsic discipline, so it must meet the common principles of human society. The principles of universe and the life principle of mankind, which are the environment in which human beings live, were reflected. As a result of deriving these common principles, qualification requirements as the intrinsic disciplines of business administration can be defined. The new business administration discipline is constructed in three fields. Business philosophy, a theory of manager, and business administration skills are three sub-fields of new business administration. We define the detailed structure of each field of new business administration and present the main research topics. In the future, further research is needed to deepen the culture of essence in business administration, and it is necessary to study the construction of the new business administration theory in detailed field.
