      • 鬱陵盆地 남단해역의 地磁場 特性 및 磁氣異常 解析

        박찬홍,석봉출 한국해양학회 1991 韓國海洋學會誌 Vol.26 No.2

        울릉분지 남단해역의 해상전자력치와 인근 육상고정관측점에서 장기관측한 지자기 자료로부터 지자장의 거동을 부식하고 자기이상분포를 해석하였다. 육상공정관측점에 서 14일에 걸쳐 지자상을 연속측정하여 연구지역 지자상의 변화양상을 분석하였으며, 해상에서 측정된 전자력치의 일련화보정에 이용하였다. 연구지역의 자기이상분포는 해 저지형의 변화에 의한 영향을 거의 반영하지 않는데, 그 원인은 주로 퇴적층하부의 기 반암분포에 있다. 자기 이상분포로 볼 때 연구지역은 그 특성을 달리하는 2구역으로 구분된다; 연안 대륙붕을 따라서는 최대 약 600 nT의 파장이 짧고 진폭이 큰 자기이상 분포가 나타나며, 그 동쪽으로는 해저지형의 큰 변화에도 불구하고 자기이상치가 단순 히 감소하면서 완만하고 진폭이 작은 저자기이상대가 분포한다. 연안의 고이상대는 자 기이상분포 형태 및 인근 육상지질분포 등으로 미루어 볼 때 화성관입체나 분출암 등 의 존재에 의한 것으로 보이며, 외해쪽의 저자기이상분포의 주요 원인은 자력원인 기 반암의 심도가 깊은 데 있다. 외해지역의 저자기이상대 내에서 선정된 3개의 자기이상 단면으로부터 스펙트럼 분석방법을 적용하여 구한 기반암까지의 심도는 외해로부터 차 례로 7.0 km, 5.0 km, 2.6 km 이며, 이는 기존의 탄성과 탐사 및 시추결과에 잘 대비 된다. 울릉퇴적분지의 특정적인 저이상대 및 자성기반의 심도분포가 분지의 생성과정 및 형태와 함께 Yamato 분지와 Japan 분지등 동해내의 다른 분지들과 유사한 것으로 보아, 연구지역인 울릉분지 남단에서의 자성기반도 Yamato 분지와 Japan 분지에서 정 의된바 있고, 주로 화산응회암과 현무암이 흔재되어 있으면서 자성이 낮은 것으로 알 려져 있는 L-2층에 대비할 수 있다. Marine total magnetic intensity over the southern part of the Ulleung Basin and geomagnetic data measured at a land base station are analyzed. Fourteen days observation of geomagnetic field at a fixed on-land base station showed how the geomagnetic field around the study area behaves. geomagnetic data at the base station can also be used as correction data for a diurnal variation. Magnetic anomalies in the study area do not reflect an effect of sea bottom topography but mainly subsurface basement. The southern part of the Ulleung Basin can be devided into two zones according to a different anomaly pattern; along the coastal shelves the isolated anomalies with a short wave and a strong amplitude are dominant, and toward the open sea the anomalies become much more subdued. The high anomaly zone adjoined to land is interpreted to be caused by granitic intrusives or volcanic rocks, and the weak anomaly zone to the outer sea to be arisen from an existence of deep basement. A spectrum analysis is applied to estimate magnetic basement depths from three anomaly profiles with a long period and a weak amplitude toward the outer sea. The calculated depths are 7.0km, 5.0km, and 2.6km respectively from outer profile. The basement might be correlated with the mixed layer of tuff, basalt, and sediment, which had been defined as L-2 layer in the Yamato basin and the Japan Basin.

        School has a responsibility on its students for making their ideal sense of values and guiding them correctly to physical, mental and social health. If we consider this fact, we'll understand the reason why the physical education in middle school has a awful lot meaning to the students. So the purpose of this study is to investigate the influence that an Intramural Sports Involvement of a Middle School has on social implications development. The subject of this study were 330 non-athletes Middle School students in Daejeon Metropolitan City selected by the stratified cluster random sampling. And I studied 317 students among them finally. For the method of collecting the data, I chose the questionnaire written by Jung, Bum-Mo(1971) and standardized by the study of Han, Tae-Ryong. And the numerical value of this data was Cronbach' a=.62 For analyzing the data, I used the technical statistics and the one-way ANOVA. So the conclusion of the influences that an Intramural Sports Involvement of a Middle School has on social implications development. 1. The development of socialization according to the vital statistical has similar differences among groups. About the difference of the development of socialization according to the gender, male students are superior to female students in direction and self control and female students are superior to male students in stability and social contact. About the difference of the development of socialization according to the grade, lower graders are superior to higher graders. 2. The development of socialization according to an Intramural Sports participation has similar differences among groups. About the difference of the development of socialization according to the time of the participation, the activity and the direction are proportional to the time or the participation. And about the difference of the development of socialization according to the period of the participation, the activity and the self control are proportional to the period of the participation.

      • 체육교사 리더십 행동유형에 따른 학습태도 분석

        박찬홍,김기성 公州大學校 스포츠科學硏究所 2005 스포츠科學硏究所論文集 Vol.17 No.-

        The purpose of this study was to know the effect of learning attitude of students in physical training class according to physical educators' leadership behavioral types. To verify the hypothesis, girls' middle school students were selected as stratified sampling. That is 3 middle school located in Tae-an, Chungcheongnam Do. In real research, the number of students is 245. The questionnaire for learning attitude used in this study was the one that was made up and developed by KEDI(1992). Also for this study, the questionnaire of leadership behavioral types for physical educators was applied what Jung Moo-young(1977) has reconstructed based on Lewin, Lippitt and White's study(1939) which had classified 3 different leadership behavioral types - the democratic, the laissez-faire and the authoritarian behavioral types. In data processing for verifying the hypothesis, MANOVA were used. The results analyzed by hypothesis and methods are as followed; 1. Students perceive their physical educators as the democratic type most. 2. There was a great significance between the students' perception of the teacher's leadership behavioral types and their learning attitude. In the Democratic type, students who had positive perception on their teacher have marked higher than those who perceive their teacher to be non-democratic. Also in the authoritarian and the laissez-faire type, students have made higher than in non authoritarian and non laissez-faire type. therefore, students who perceive their teacher as the democratic have marked the highest score in learning attitude.

        The purpose of this study were to analyze the objectives and contents of the seventh curriculum of physical education in the elementary school to help understand the curriculum, to present the course of elementary school physical education to the elementary school teachers, and to detect problems to be a help to the next curricular revision. After analysis on this research, I got the conclusions as follows ; First, the subject objectives were analyzed on the basis of the standard of objective classification by Bloom, Bucher, Barrow, Nash. Stoodley, Brownell & Hagman, Hetherington, Irwin, and Willgoose. Second, the unit objectives were analyzed on the basis of the standard of objective classification by Bloom, Bucher, Barrow, and purpose process curriculum framework. Third, the sixth and seventh curriculums were compared and analyzed. Fourth, the contents of the seventh curriculum of physical education were analyzed. The conclusions about analysis of the objectives and contents of the seventh curriculum of physical education in the elementary school are as follows ; First, by the standard of objective classification of nine scholars as Bloom, Bucher, Barrow and so on, we can understand same distribution of term statement about psychomotor, cognitive and affective domain, this shows a unity of objectives of physical education in the seventh curriculum of physical education. The standard of objective classification as Nash, Stoodley, Brownell & Hagman, Hetherington, Irwin, Willgoose, etc. shows same term distribution, and this reflects the character of synthetic subject which shares functional, scholastic, prescriptive character of the seventh curriculum of physical education. Second, in the analytical conclusion by the standard of classification of Bloom, the terms stated best are basic exercise of psychomotor domain, exercise method of cognitive domain and exercise function of psychomotor domain. Many term distributions in the 'basic exercise' of psychomotor domain are because of the seventh curriculum of physical education in the elementary school setting the basic in the moving education simulation, and emphasize a method and function of exercise to take shape various moving desire of students. In the analytical conclusion by the standard of classification of Bucher, the terms stated best are a motor function of developmental domain of exercise, a basic exercise of developmental domain of exercise, a method of exercise of cognitive domain. The seventh curriculum of physical education in the elementary school is based on moving education simulation, and show up many term distributions about 'motor function' and 'basic exercise' of developmental domain of exercise. The method of exercise is emphasized to take shape various physical activity and moving desire. In the analytical conclusion by the standard of classification of Barrow, the terms stated best are a understanding about the health of cognitive developmental domain and principal of good physical motion exercise, sports' function of developmental domain of psychological exercise and attitude of social developmental domain. The subordinate objectives of the seventh curriculum of physical education in the elementary school emphasize a motor function that participate actively to various exercise, and improve sports function with a background about understanding of principal of health and good physical moving exercise to improve physical strength and psychological health, and emphasize desirable motor attitudes. In the analytical conclusion by the standard of classification and purpose process curriculum framework(PPCF), the terms stated best are conquest of environment, social interaction and individual developmental domain, and each conceptional element has same distribution so as character prescribed in the seventh curriculum of physical education, don't emphasize only one domain, cognition or affective domain but pursuit external value, that is, realization of moving and healthy preservation and improvement, affective refinement, social cultivation through physical education in the elementary school to contribute to improve quality for life of the human. Third, the conclusions of comparison and analysis about the sixth curriculum and the seventh curriculum of physical education are nearly same, but the seventh curriculum is presented to nation common basic of physical education curriculum bounding elementary, secondary school. And the 'method' section is divided a teaching & learning method and a standard of textbook's development and discussion, and the standard of textbook's development and discussion that undertakes a important responsibility to practice of curriculum was presented newly. The contents are organized by objective and affective domain.

      • 울릉분지에서의 선상중력과 위성중력 통합에 의한 중력 해상도 향상 및 해석

        박찬홍,김정우,허식,원중선,석봉출,유해수,Park, Chan Hong,Kim, Jeong U,Heo, Sik,Won, Jung Seon,Seok, Bong Chul,Yu, Hae Su 한국지구물리물리탐사학회 1999 지구물리 Vol.2 No.1

        최근 공개된 위성중력을 이용하는 오차 최소화 기법을 적용하여 선상중력내 존재하는 구간 측선간 오차나 교차점 오차를 성공적으로 보정하였으며, 보정된 선상중력을 위성중력과 결합하여 고해상 중력분포를 도출하였다. 오차 최소화 과정에서 울릉분지의 선상중력은 위성중력보다 장주기 성분에서 상대적으로 크게 보정되었으나 단주기 성분은 그대로 보존되었다. 이것은 선상중력이 갖는 단주기의 중력 성분이 훼손되지 않은 채 안정되고 연속성을 갖는 장주기의 인공위성 중력분포에 잘 접합될 수 있다는 것을 보여 준다. 통합된 후리에어이상도는 위성중력의 장주기 성분과 선상중력의 단주기 성분을 모두 표현하므로 해저지형 및 지질분포의 해석에서 보다 상세하고 신뢰성 있는 정보를 제공한다. 후리에어이상은 수심이 깊은 분지 중앙 지역이 해저산이나 대지 등 높은 지형으로 이루어진 분지 주변부 보다 상대적으로 낮게 분포하는 등 전반적으로 해저지형의 분포 경향에 부합되어 변화한다. 그러나 대륙사면을 이루고 있는 분지의 서쪽 및 동쪽 주변부를 따라서는 지역적으로 함몰된 퇴적기반과 두꺼운 퇴적층 및 대륙 주변부에서 특징적인 가장자리 효과로 인한 저이상대가 발달하고 있다. 울릉도 북동부에 위치한 한국대지 및 울릉대지에서 북동-남서방향의 선형분포를 갖는 중력이상은 동해가 열개되는 동안 균열된 지각 사이를 따라 일어난 화산활동의 결과로 형성된 해산이나 관입암체가 선형으로 배열함으로서 기인한 것으로 해석된다. 선형으로 배열된 고중력분포는 울릉대지 서쪽 경계부에서 급구배를 보이는 북북서-남남동 방향의 직선적인 중력분포에 의해 절단되고 있는 데 이 급구배의 중력이상은 울릉대지 서부 경계를 이루는 단층선애에 기인한다. 울릉대지가 서쪽으로 뚜렷한 단층 접촉을 나타내고 있으나 지형적인 형태에 있어서 대비되지 않는 것은 울릉대지가 단층을 경계로 분리되어 이동되어 왔을 가능성을 시사한다. 분지의 중앙 북동부에서는 수심이 깊어지는 데 비해 중력치는 오히려 높아지는 경향을 나타내고 있는 것은 맨틀이 주변부에 비해서 상대적으로 천부에 존재하고 있는 것이 가장 큰 요인이며, 해저지각의 두께가 얇은 대신 지각의 밀도가 주변 대륙보다 높은 데도 기인한다. The errors between track segments or at the cross-over points of shipborne gravity were successfully reduced by applying a cross-over error adjustment technique using satellite gravity. The integration of shipborne and satellite altimeter-implied free-air gravity anomalies after the cross-over error adjustment resulted in a high resolution gravity map which contains both short and long wavelength components. The successful adjustment of the cross-over errors in the shipborne gravity using the satellite gravity suggests that the shipborne gravity can be combined with the satellite anomalies characterized by a stable and long wavelength component. The resulting free-air anomaly map is evenly harmonized with both short and long wavelength anomalies. Thus the corrected anomaly map can be better used for the geological interpretation. Free-air anomalies with more than 140 mGal in total variations generally correspond to the seafloor topographic changes in their regional patterns. A series of gravity highs are aligned from the Korea Plateau to the Oki Island, which are interpreted to be caused by seamounts or volcanic topographies. The gravity minima along the western and southern shelf edge are associated not only with the local basement morphology and thick sediment fill at the continental margin, but also possibly with the crustal edge effect known for passive continental margins. Series of NE-trending linear anomalies are possibly caused by a swarm of volcanic intrusions followed the initial opening of the Ulleung Basin. The linear high anomalies in the Ulleung Plateau are terminated by the straightly NNW-trending anomalies with a sharp gradient in its western boundary which indicates a fault-line scarp. The opposite side adjoined with the fault-line scarp shows no correlation with the fault-line scarp in geometry indicating that the block might be horizontally slided from the north. A gravity high in contrast to the deepening in seafloor toward the northeastern central Ulleung Basin is probably responsible for the thin crust and shallow seated mantle.
