Lorenz 곡선의 집중지수에 의한 전남 인구집중도 측정과 분석
조혜종 전남대학교 지역개발연구소 1983 지역개발연구 Vol.15 No.1
This study aims at the measures of population distribution by Si(city) and Gun in Jeonnam by the index of concentration from Lorenz curve. A device for graphic presentation and two index numbers associated therewith have been most widely used for measuring conentration. These are : 1) the Lorenz curve and Gini's $quot;concentration ratio$quot; and 2) $quot;index of concentration$quot;, or more generally the $quot;the index of dissimilarity.$quot; The former expresses the area on the graph between the Lorenz curve and the diagonal as a proportion of the total area below the diagonal, and is given by the formula : 10,000 CR =(수식)(X : cumulative percentages of population, Y: cumulative percentages of area, k: the number of area) units). The letter, the index of concentration, algebricially is simply the maximum of the set of k value of (X_i-Y_i). Geometrically, it is the maximum vertical distance from the diagonal to the curve. This study is approached by the latter and the indices of concentration each Si and Gun are shown on the graphs (1)-(29). Some results are drawn as follows : 1) The index of concentration in Si is much higher than that of Gun because most Si-boundaries are overbounded, so there is a Great Rap in the population densities of an areal units Dong-s between in urban Centers and on the outskirts. 2) Damyang, Gurye, Gwangsan, Jangheung and Gwangyang Gun-s show high values in the index of concentration, while Yeocheon, Wando, Sinan, Jindo, Goheung, Muan, Gangjin, Naenam and Hampyeong Gun-s, most of which are coastal regions or islands regions do low values. 3) To make an object of those areal units within the first fifth order each Si and Gun, the primacies of Si-s like and Geumsung are high which are small or new Si-s, while those of Guns are high which have older or traditional Eub-s within the boundaries. 4) The index of concentration has a tendency to be related to the man/land ratio(crude density of population) and inversely related to the man/cultivable land ratio(physiological density). 5) Index of concentration has no relation to the population change in number of age composition. This means that we have outmigration not in defined given regions but in almost all rural parts and in the same age groups simultaneously. Finally, population problem being one of the most serious problems mankind has ever faced, birth control is very important in relation to the population problem, and the redistribution of population is important as well. We, therefore, need to analyse small-areal units to perform some reasonable policies for a redistribution of population.

조혜종,오병희 한국 지리·환경 교육학회 1997 한국지리환경교육학회지 Vol.5 No.2
An Inquiry learning is necessarily requested in order to achieve the objectives of geography learning through geographical thought and an enhancement of problem-solving ability. This study covers the following contents: ① Selection and analysis of the principle of an inquiry learning adequate to geography learning ② Understanding cognitions and actual conditions of an inquiry learning method of the high school teachers ③ making a teaching plan for an inquiry learning('urrit of climate') and investigating its propriety. First of all, even though many high school teachers admit the proprieties of an inquiry learning in all aspects-the objectives, contents, activity and appraisal-in geography learning, they do not make a radical change in their cognition toward an inquiry learning method. It is quite necessary that many different types of classwork are to be performed for coming the 21st century edcation in which a creative and leading ability should be of classwork is under carrying-out owing to the presest examination system. Institutional support for innovation is needed in which a teaching-learning system is dynamic and self and developing as well as a change in teacher's behavior.

남부이태리 Agri 강 유역분유에 관한 연구 : 항공사진을 통하여 Through Aerial Photo and Photo interpretation
조혜종 서울대학교 지리교육과 1979 지리학과 지리교육 Vol.9 No.1
Fieldwork area covers Agri River Basin: Sant' Arcangelo, Aliano, Gannano and Colobraro, Basilicata, S. Italy. This area falls under the toe of Italy and was flooded by the sea in Tertiary Period. In terms of geological formation, it is mainly covered as the one of Cretaceous Epoch of Mesozoic Era and various formations of Cenozoic Era, but it is characterized by the fact that it has a break of Oligocene Epoch between Eocene and Miocene. The landform classification in this area is according to some geomorphological criteria such as process, morphological feature, lithological material, and its stage and origin. Geomorphological units are classified as: 1) Forms of Denudational Origin, and 2) Forms of Fluvial Origin. The former is sub-divided into: A) Forms Non Structurally Controlled, and B) Forms Structurally Controlled. The Geomorphological units in this study area can be stated as followings: 1) Badland 2) Sheet, Rill & Gully Erosion 3) Mass Movement 4) Rolling Landscape 5) Planation Surface 6) Plateau 7) Hogback 8) Mono-clinal Ridge Zone 9) Crest Zone 10) Flood Plain 11) River Terrace 12) Infilled valley, and 13) River channel. Geomorphological units can be sub-divided in detail by criteria such as ground relief, slope form, and its length, dissection rate, drainage density etc. The division of geomorphological units follow roughly the lithological boundaries, and from this fact, we can recognize that landforms are closely related with lithological materials, processes, and stages. Aerial photo and photo-interpretation has much value in geomorphological study. Practical use of aerial photo began in science in the 1930's, and thereafter its value has been increased. I confirm that aerial photo graphy aids in geomorphological study and it is also a nice tool for landform classification. As there are some problems in photo-interpretation, we need continuous study in this field.

조혜종 서울대학교 지리교육과 1988 地理敎育論集 Vol.19 No.1
The population growth in Utah has increased at high speed since Mormon settlement in Salt Lake Valley. Demographic characteristics in Utah are, first of all, outstanding high fertility, which comes from a higher percentage of females in the child-bearing ages compared to the nation; and Utah women in the same age group have a much higher fertility rate, almost double that of the rest of the country. Utah's infant mortality rates have remained below Mt. States and national rates since 1966, but the gap has been narrowing since 1975. As a whole, the ages at first birth for Utah women are older, inter-pregnancy one year or shorter, and birth numbers are greater than the national level. All of these are related to the recent growing infant mortality rates. Utah's high fertility, on the other hand, can be attributed to the balanced sex ratio in early Utah, an unusual case for a new settled area. We can expect growing birth rates even for the next generation in view of a striking youth ratio and also as the young ages become a heavy burden for the improvement of income level. The Mormons are likely to take a more traditional position in favor of the motherhood role than are the non-Mormons. Even though the 1980 census indicates that female employment rates in Utah are virtually identical to the national rate during the years when children are young, they devote less time to employment that do most women. In general, higher socioeconomic status often has a negative relationship with fertility rates. Among Mormons, however, family income and women's education both have a positive relationship with fertility. In comparison to other religious groups, the Mormons are positive towards marriage or remarriage, and less positive than the Catholics or the Protestants to familly dissolution like divorce or separation. The Mormons' effects on the demographic characteristics in Utah must be completely accepted in view of demographic history, the percentage of Mormon numbers, or very simliar demographic patterns between the Utahns and the Mormons. Social mobility in population due to urban development, however, breaks down not only religions, or cultural ties but also demographic characteristics. The Mormons, especially urban Mormons, have gradually lost their Mormonisms, turning large family-oriented traditions into smaller ones. Even though the Mormon characters have lived with the Uthans so far, we can not expect it anty more in the future.
