      • 地磁氣 原因論에 關한 考察

        崔福源 釜山敎育大學 1973 부산교육대학 논문집 Vol.9 No.1

        The aims of this paper is to analize the existing theories in formulation process of geomagnetisms, point out theoretical weakpoints of these theories, and seek some possibilities of new formulation of theory concerned. The results of this study are as follows: 1. Precise quautative research are necessary for proving these theories, although are there no rejections about Hall Effect-and Twisted Kink theories of classical hypotheses. 2. Explanation of the existence of normal homogeneous dynamo are directly linked to the question of calculation ligen value mathematically. 3. Seeking the normal situation of B-G-L model is equael to calculating the unique value and function of Homogeneous simultaneous differential eguation. 4. It seems difficult to treal simply flow movement as unchangeable value in formulating of reverse theory of earth's magnetic field. 5. It seems that regional magnetic field has its causation in nuclei, and local magnetic in earth's crust.

      • 局地氣象의 特性 : 釜山의 바람 Winds of Pusan Area

        崔福源 釜山敎育大學 1968 부산교육대학 논문집 Vol.4 No.1

        Although lots of meteorogical observations have been made by varieties of schools and county offices until recently, they are stilld thought to be merely superficial observations of weather, not to be scientific ones with which we can find out the law of nature. Accordingly, I aim at scrutinizing the wind of Pusan district, which can be said to be a phase of regional weather conditions, by the use of records made by central Meteological Office as its material. In considering the contents of this thesis points are itemized as followings: (A) Order of Research 1. Annusl average 1) Actual condition; to make annual average, wind nose, and wind star. 2) Internal structure; to look into the interrelation ship among the curve of freguency destribution of annual measurements, the curve of frequency and average numbers of years. 2. Changes of long years 1) Tendency of Long period Time; to research tendency of long period of time on the assumption that there are the first and the second change, and index change. 3. Change of a year 1) Actual Condition; to illustrate by diagram of annual average. 2) Internal structure; to find out charateristics of four seasons. 4. Change of a day 1) actual condition; to illustrate by diagram of every day average. (B) Contents of Research 1. Frequency of wind direction(1957-1966) 2. Average speed of wind(1966) 3. frequency of gales(??13.9m/s)(1964-1966) 4. Number of gales days(1961-1966) 5. Percentage frequency occurrences of concurrent wind speed and direction within classified ranges(1964-1966)

      • 국민학교 자연과 상호개념 형성을 위한 평가자료 개발에 관한 연구

        최복원 부산교육대학교 과학교육연구소 1980 科學敎育硏究 Vol.5 No.-

        Since we adpoted the discipline curriculum in koeran elementary school science, we have not yet developed the appropriate instruments for the measurement of the concepts in the elemantary science education in Korea. Although both the formative and summative evaluations are strongly recommanded in the discipline centered curriculum, We have neither enough knowledge that in nesessary, nor the formative and summative evaluation instruments in practical level. Therefore the purpose of this study is to make the formative and summative evaluation instruments for the interaction that the elementary school children have and to give some suggestions to the teachers for the application of these instrments. The study method and the detailed. plan of its process are as the instruments. 1) Anallysis of the units of the interaction according to the grades. 2) Modeling of the hierachy of the units and of the learning purpose. 3) Operational definition of the individual concept. 4) Duaral classification.

      • 部分日蝕 관측 연구 : 1987년 9월 23일

        최복원 부산교육대학교 과학교육연구소 1987 科學敎育硏究 Vol.12 No.-

        We observed the partial solar eclipse on 23 Sep. 1987 by photographic method. From these photographs, we acquired following results. 1. Thogh the photographic method for solar eclipse were fully examed and prepared, the sky at the time of which eclipse occured was very frequently changed from bright to cloudy and exposure time was not adequate at each time. Some of the photograpgs are not accurate in direct focus photograph of refracting telescope. 2. Multiple exposure photograph of solar eclipse was good. In 50mm single reflex camera, the full eclipse scene was not acquired. 3. The ratio of angular diameter of sun and moon was 0.959. 4. The central distance of sun and moon was changed and this is the result of complex movement of sun and moon. 5. Different methods for calculation of the area of bright solar part and ecliptic ratio in solar eclipse are used. 6. By calculating the ratio of the central distances of sun and moon from earth, sun and moon was positioned nearly the farthest point of aphelion. 7. In the result of photographs of solar eclipes, the starting time of eclipse was 10^h44^m and the time of largest eclipse was 12^h 25^m and finishing time was 13^h 45^m.

      • 局地氣象의 特性 : 1984년 8月달의 智異山一帶

        崔福源 부산교육대학교 과학교육연구소 1984 科學敎育硏究 Vol.9 No.-

        The meteorological phenomena of the mountainous areas of Chili Mt. showed the characteristic of the mountainous weather conditions very well. 1. The possibility of clear day is 0.41 and that of cloudy day is 0.58. 2. The relation between average cloud amount C, clear day c, and cloudy day αis C=a+b(α-c)/n, where constants a and b are varied in different local sites. In the mountain ridges a=5.35, b=4.65 and in the valleys a=5.6, b=4.3. 3. For a month of August the amount of rainfall records 593.5mm, which is affected by typhoon. In the period of typhoon the amount of precipitation is 9.8mm/h and in the sudden shower 8.5mm/h. 4. The winds which blow from southeast direction or northwest direction prevail, but the changes of direction and speed of wind are severe. The speed of SE wind is smaller than 8.0m/s. 5. Diurnal range of the temperature is 13.5℃ and the largest difference of the temperature of day and night is 16.6℃.

      • 寫眞測光에 依한 量間物質의 選擇吸收에 關하여 : An Application of photographic star-brightness measuring

        최복원 釜山敎育大學 1974 부산교육대학 논문집 Vol.10 No.1

        In this study, star quantities of Orion and Ursa Major were calculated respectively in terms of photographic measuring of star brightness. The results of this study are as follows: 1. Under the condition of 24 shutter second, difference in star quantities between Orion and Ursa Major is found. 2. Under the condition of 1 minute, same rate of increase in star quantities is found. 3. Under the condition of 2′30″, it is found that the increase rate of star quantity of Ursa Major is larger than that of Orion. 4. According to above facts, the multiplicity of Intergalactic material in Orion is inferred. And above phenomena seem to be results of selected ahsorption of Intergalactic materials.
