        지능형 농기계 기술 동향

        김완수,김환선,공소윤,이중용,임종국,김완수 사단법인 유공압건설기계학회 2023 드라이브·컨트롤 Vol.20 No.4

        The purpose of this study is to suggest the direction for the development of intelligent agricultural machinery technology in the Republic of Korea. For this purpose, intelligent technology of agricultural machinery was divided into autonomous agricultural machinery and tractor-implement intelligent communication technology. Then, a survey and analysis of a previous study of the Republic of Korea and foreign countries were conducted. GNSS-based autonomous driving technology is still widely used worldwide, and recently, as research on camera and LiDAR-based autonomous driving is actively progressing, autonomous driving technology is becoming more advanced. ISOBUS-based technology is being developed worldwide for intelligent control of tractor-attached implements, and major global agricultural machinery manufacturers are actively applying it to their products. However, although some ISOBUS technologies are being researched in the Republic of Korea, there are no cases of application on agricultural machinery yet. Therefore, to be globally competitive in the agricultural machinery manufacturing industry, there is an urgent need to advance autonomous driving technology and commercialize agricultural machinery using ISOBUS technology.

      • 共振方式에 의한 金屬줄의 張力比較 硏究

        金完洙 서울産業大學校 1985 논문집 Vol.22 No.1

        This paper focuses on the method of measurement of tension. A metal wire of definite length vibrates with proper frequency. Tension has been measured by setting up a monocord and charging alternative current for the purpose of studying corelation between tension and stationary wave. The result is that a thin wire in diameter can be used for the precise measurement of small tension and a thick wire is suitable for large tension. When an iron wire is used instead of a copper wire, a better precision can be achieved in the measurement of the same tension.

      • 부산 인근 연안해 지역의 퇴적환경 연구

        김완수,석동우 한양대학교 이학기술연구소 2002 이학기술연구지 Vol.5 No.-

        부산 인근 연안해 지역의 퇴적환경을 알아보기 위하여 천부지층탐사와 퇴적물 입도분석을 실시하였다. 연구지역은 낙동강에서의 미세한 퇴적물의 유입이 상당한 지역으로 유입된 퇴적물은 조류와 대마해류에 의해 직접적인 영향을 받는다. 퇴적물의 분포 상태는 내해에서 니질(mud)퇴적체가 두껍게 발달하고 있으며, 외해쪽으로 수심이 증가하면서 퇴적층의 두께도 얇아진다. 이러한 퇴적체는 홀로세 기간동안 퇴적된 최적물이며, 음향기반 하부의 퇴적물질은 저해수면 시기의 잔류퇴적물로 사료된다. 또한 탄성파 반사 형태로 과거 낙동강 하구의 흔적과 가스 유기물질의 존재 가능성을 확인 할 수 잇었으며, 분석된 천부지층탐사 해석과 입석분석 결과에 의한 퇴적물 분포 양상은 서로 잘 일치하고 있다. In order to investigate the depositional environments in the coastal sea off Pusan area, shallow seismic profiling explorations and grain size analyses were carried out. The study area was supplied by a significant amount of fine grain sediments delivered by the Nakdong River, whose distribution was again influenced by tidal currents and the Tsushima current in the coastal sea. Thick mud deposits are found along the shallow near shore area and the thickness of the deposit decreases in the open sea direction as the depth of water increases. The mud deposit is believed to be of the Holocene Epoch and the acoustic basement is interpreted as the relict deposit formed during the Pleistocene low sea-level period. Based on the characteristic seismic reflections patterns, the paleo-Nakdong River channel and the possible presence of organic gas bubbles are recognized. The characteristics and distribution of the sediment bodr based on the interpretation of the shallow setsmic profiling and the results of gain size analyses are consistent with each other.

      • 道德性의 範疇的 考察

        金完洙 서울 敎育大學校 1975 論文集 Vol.8 No.-

        The purpose of this study is not to define the meaning of morality but to clarify the categories of it. This categorical analysis is necessary for the purpose of the tentative definition of morality. To do this, I have reviewed these in the six fields as follows: 1) Moral behaviour consists of all the various things people do in connection with moral rules. the training procedures and learning process of moral behaviour do not differ in principle from those found in other sorts of behaviour. Moral man is little more than a complex net work of conditioned responses and learned habits. 2) aCCORDING TO fRUCIAN DOCTRINE, Moral man is pictured as a lonely and rather helpless ego struggling to satisfy the insistent demandsof an amoral id without angering the watchful and punitive parents who are now permanently installed within his own mind) in a real world that is, in the last analysis, totally indifferent to his welfare. 3) Morality is not just a matter of rules but also of dispositions or traits, intention, reasons, and motives. 4) Social-group theory sees moral man essentially as a conformist who complies with the expectations of there out of an imperative need to be accepted by them. 5) Accroding to the ethical theories of the moral judgement, morality is depend upon a priori or a posterior principles; the metaphysical theories of value, naturalists, deontologists, new naturalists, deontolgists, new naturalsts, emotivists and the modern one who asserts the third principles. Among these the most difficult and unsolvable argument is the theories of emotivists. 6) The ultimate sanctions for morality are religious. Moral education is impossible without the habitual vision of greatness. 7) In Taoism Tao, inBuhdism Buhdha, in, Confucianism Hyo, and in Korean Humanism In-Nae-Cheon are the basic moral concepts of morality. They are, so called, the naturalistic deontologist. Consequently I have understood the concept of morality requires to solve what the relationis. But the problem of relation is connected with the very difficult one. It includes all problems from the logical relation to the metaphysical one. Expecially it must answer to what is implication and negation. Implication and negaition are the basic problems of philosophy. These two have to face with the "Other"problems. Therefore morality will be defined after the more close examination of these kinds of researches.
