濟州島 無文土器 文化硏究 : Especially on archaic fine arts
文基善 제주대학교 1973 논문집 Vol.5 No.-
This thesis is meant to investigate the origin of traditional culture peculiar to Cheju-do so that we can study the formative culture on the basis of the primeval era of Cheju-do, and to attempt to make an introductory description of the main points about our traditional culture. Such a study must be made by means of archaeological method for lack of remains of the past and bibliography concerning it. But it seems to me that it is very difficult to describe the aspects of that kind of culture fully. Quite recently, in many areas of Cheju-do, there are several relics and vestiges of ancient civilization-"Jisukmyo"(propping stone tombs), menhir, stone implements made by beating, stone implements made by rubbing, a fossil deer, shell-heaps, primitive men's dwelling-place and what not-were excavatted, and scholars concerned have a keen interest in the discovery of the ancient fine-artistic data in the prehistoric age. I think these archaic cultural assets have academic value and they provide us with reliable sources to study the prehistoric culture in Cheju-do, besides being the properties inherited by our ancestors. Maybe they are good proofs in pursuing the prehistoric culture in Cheju-do. If we want to search the origin of the culture of Chejudoian ancestors in agriculture, it would be better to make allowance for the following facts. They, our ancestors, began their living by hunting wild animals, fishing in the sea and farming in the field years later the Stone age (the Palaeolithic age and the Neolithic age) came, when our ancestors domesticated wild animals and kept them. Anyway, I believe the form of Chejudoian ancestor's culture will be examined gradually, as the farming implements in the age of both metal goods and stonework will be excavated and as the corpse of animals and plants or their fossils will be surveyed.

In a high speed vehicle, power collection is a difficult task. To avoid the difficulty, a linear generator is used in an attractive type vehicle propelled by a linear synchronous motor (LSM). This study shows characteristics of a linear generator using Fourier series. Resultant air gap flux in the air gap and induced emf in a linear generator coil are shown. Air gap flux is divided into three parts, those are, flux by field winding, armature winding and linear generator winding.

Large fault current is expected in superconducting power system which will be built in the near future. Short-circuit capacity of superconducting machines consisting power system is much lower than that of conventional machines. Therefore superconducting switch is needed to prevent rapid increment of fault current. This paper proposes the non-inductive superconducting switch to speed the switching and calculates inductance by finite element method. Inductance of proposed superconducting switch decreases to order of ?? comparing with that of conventional one.

It is the most important affairs that all universities implements the selection of the freshmen annually, The more a university get a many student obtained the high score in student achievement test(SAT), the more it have the smart and competent students who make a reputation of the university in the future. In the present, the criteria of the selecting the freshmen are the score in student achievement test(SAT) and the higher school records. It is need to test the validity of the criteria whether it is reasonable, or not.. Thus, the purpose of this study was to explore the validity on the criteria, to analyze the relationship the credit with one's hometown and with the pattern of dwelling. It should be consider that it is need to retest on the criteria and to explore a new criteria because it was identified in this study that there are no the relationship the credit in the university with the score in student achievement test(SAT).

The objectives for this project is to develop the test equipment of the automobile alternator's characteristics. The main activities and the results of this project are summarized as follows. 1. State-of-the art analysis of automatic test equipment for factory automation. 2. System analysis and design the test equipment of the automobile aiternator's characteristics. 3. Development of software for the alternator's performance test. 4. Development of hardware for control system. 5. Total system integration test. We developed the automatic test equipment for automible alternator's characteristics with personal computer which basis on the microprocessor pheriperal devices and sensing devices. We hoped that our developed systems are very useful in automobile alternator's test equipment and that the interest for factory automation is incresed in industry environments.

This study is to carry out on optimum proportioning of doubly reinforced concrete rectangular sections based on both working stressed design theory and ultimate stressed design theory for the minimum cost design. Cost objective function for minimizing the construction cost is obtained by considering the cost of steel, concrete forming and the cost of increasing the building height. And the design constraints used are the flexural moment, ratio of the area of compressive reinforcement to tension one, ratio if the width to the effective depth, and the minimum steel ratio. The objective function and design constraints are transformed into the set of successive linear programming problems using the Taylorseries expanson and computer programis developed for the implementation of the above formulations and algorithm. By the numerical examples, it has been observed that the optimum proportioning of doubly reinforced concrete sections results in significant savings in the construction cost, and especially comparison of method of design is performed in economical view.

In case of using the numerical control machine(CNC) for the metal cutting machine, the accuracy of the interpolator is more important than the speed of it. This paper presents a interpolator having high accuracy and simple algorithm. The interpolator is realized by general purpose 6502 microprocessor without designing a special purpose processor. Error generated by the interpolator is less than half of basic unit and the speed of the interpolator is faster than that of metal cutting machine. And the various functions, such as speed control function, manual operating function and material finishing function are all operated as expected.

중국 최초의 달 착륙선 창어 3호는 2013년 성공적으로 달에 착륙하였는데, 본 연구는 달 착륙 거동을 분석하기 위하여 창어 3호의 실시간 달 착륙 동영상에서 달 표면 크레이터의 움직임을 추적하고, 이를 동영상에 표시된 고도 및 소요시간 정보와 결합함으로써 달 착륙 직전의 4차원 거동을 추출하였다. 이를 위하여 고도 129 m에서 촬영된 달 표면 영상에서 크레이터 에지 1개소를 특징점으로 선정하였고, 이 특징점을 성공적인 달 연착륙에 있어 가장 결정적 구간인 고도 50 m까지 하강하는 동안 영상처리를 통하여 연속적으로 추적하였다. 본 연구는 창어 3호의 공중정지 및 장애물 회피 기동을 포함한 실제 착륙 거동의 상세를 복원함으로써 달 착륙 성공전략을 분석하였다. China’s first lunar lander, Chang’e-3, successfully landed on the moon in 2013. This research tracks movement of a lunar crater in the real-time lunar landing video of Chang’e-3 and combines altitude & time information shown in the video to extract 4-dimensional behavior just before the lunar landing. For this purpose, one crater edge in the lunar surface image at an altitude of 129m is selected as a feature point. It is continuously traced by computational image process while descending to an altitude of 50 m, which is the most decisive section in the successful moon soft landing. This research restores realistic details of landing behavior including hovering and obstacle avoidance maneuvers of Chang’e-3 and analyzes the success strategy of lunar landing.
