무인 향공기의 주요 목적은 유인 정찰기의 최대 단점인 조종사의 인명 손실을 제거하고, 원하는 지역 또는 물체를 정찰하는데 두고 있다. 업무를 수행하기 위해서는 조종사 눈 역할을 할 수 있는 카메라가 필요하며, 획득한 정보 또는 목표물이 무엇인지를 구분하여야 한다. 본 보고서는 임무수행을 위한 영상감지장치의 선정에 필요한 요구 사향을 기술하였다. The objective of the UAV removes the life loss of the pilot who is the maximum weak point of the manned reconnaissance aircraft, accomplishes the reconnaissance it is an aircraft for. The camera which will confirm the pilot substitution reconnaissance result which stands is necessary, we should confirms the target which this camera probably is what. The report which described like this demand condition against the consideration fact which is necessary to the selection of the image sensory device which is a camera which with character will be applied in UAV.

경상분지(慶尙盆地) 북동부(北東部) 영해(盈海)·영덕일대(盈德一帶)의 화강암질암(花崗岩質岩)의 흑운모(黑雲母)와 각섬석(角閃石)의 진화경로(進化經路)

The granitic rocks in the study area are divided into the schist and gneiss complex, Yongdok pluton, Yonghae pluton and Onjong pluton by their texture, fabric and relationship to the adjacent rocks in the field, Schist and gneiss complex occurs as xenolith or roof pendant in the Yongdok, Yonghae and Onjong plutons. The Yongdok pluton occurs in association with pegmatite and aplite in many places of its pluton. In the field it is obviously clarified that the Yongdok pluton is unconformably overlay by the Cretaceous sedimentary rocks. The Yonghae and Onjong plutons are gradationally changed each other, and these plutons truncate both the Yongdok pluton and the Cretaceous sedimentary rocks. Petrographically, the Yongdok pluton consists of granodiorite and granite with minor quartz monzonite. The Yonghae pluton is composed of diorite, quartz diorite, tonalite, and granodiorite. The Onjong pluton also ranges granodiorite to granite. Both the Yongdok and Yonghae-Onjong plutons are different in the constituent minerals, such as alkali feld~par, myrmekite, mica, sphene and mafic minerals. This suggests that each pluton might have been different crystallization sequence and characteristically different gological history during the crystallization period. Iron/magnesium ratio in biotite and hornblende from both the Yongdok and Yonghae-Onjong plutons gradually decrease as the differentiation index increasing in the whole rock. The decrease of this ratio strongly depend on the increase of opaque mineral contents. From the results of chemistry in the whole rocks and some mafic minerals, it is suggest that the granite plutons of the two different geological ages would have been suffered the environment of high oxygen fugacity in the process of magmatic emplacement and during the crystallization period.

스마트무인기 콘솔의 설계 및 진동ㆍ충격해석

권기한(Gi-Han Kwon),김중욱(Joong-Wook Kim),윤홍우(Hong-Woo Yoon),박형건(Hyung-Gun Park) 한국항공우주학회 2005 韓國航空宇宙學會誌 Vol.33 No.5

본 논문에서는 스마트무인기 콘솔구조의 설계개념을 소개하고, 장비의 안전성을 평가하기 위하여 충격과 진동에 대한 국방 환경시험규격을 적용하여 수치해석을 통한 주파수 응답스펙트럼을 분석하였다. 콘솔의 설계개념은 형상설계와 공학설계로 크게 분류된다. 형상설계는 콘솔의 운용성을 높이기 위한 인체공학규격을 기초로 하며, 공학설계는 충격과 진동에 대한 내구성을 높이기 위한 설계이다. 수치해석은 유한요소법을 통해 수행되었으며, 해석결과 콘솔에 설치된 6개의 탄성스프링은 충격과 진동에 대하여 충분한 감쇠를 보임이 확인되었다. This paper presents a design concept of smart UAV console system and the analysis of its dynamic response to shock and vibration. The console system design is determined by two main elements; the shape design and the mechanical design. The shape design refers to the human engineering aspects according to the military standards for ship borne equipment. The goal of the mechanical design is to provide the required shock and vibration endurance. The endurance of the system is numerically verified by means of Finite Element Method. The results of verification show that six resilient mounts installed on the console allow to sufficiently decrease the influence of the input impact wave on endurance of the system.

For this study, a total of 45 elementary students from two classes of the 5th grade in C elementary school in K province. In the experimental group, instruction using a brain-based science teaching and learning model was implemented on the unit of the Heat and Temperature and in the comparison group, a traditional instruction based on a textbook, textbook manual was implemented on the same unit. The major results of this study were as follows: First, analyzing the curriculum about the unit of the Temperature and Heat, the lesson goal and teaching-learning activities were reorganized from the science studies achievement For applying brain-based science teaching and learning model to the science learning, science teaching learning program and learning materials were developed. Second, the brain-based science teaching and learning failed to have significant influence upon the whole in the scientific inquiry skills of 5th grader for elementary school. However, it was indicated to have positive effect on the observation, classification function in the basic exploration function domain, on the controlling variables function in the integrated exploration function domain. Third, the brain-based science teaching and learning had a positive effect on the science related attitudes, especially curiosity, cooperativity in science related attitude domain. In conclusion, the brain-based science teaching and learning on the unit of Temperature and Heat was effective in the science learning.

A UAV is defined as a powered, aerial vehicle that does not carry a human operator, and can fly autonomously or be piloted remotely. UAV operations have increased dramatically during the past several years in both the public and private sectors. The utilization of UAV and the activities of diverse widening, now the challenge was how to operate and integrate UAV safely in the NAS. The purpose of this study is to look around the trend for operability of Smart UAV in the NAS and to provide its implications and the future direction of integrated operating airspace focusing on U.S. where R&D and demand of UAV are the most in the world.
