Lately, the rapid social and family system change, the entrance examination-centered circumstance in education have a negative influence not only on making up the affirmative self-esteem but also on building up the personal relationship through mutual communication with friends of the same age. Making children adapt well to school life and develop a good relationship in the class is an important subject in educational field. Thus, various school activities should offer lots of opportunities to increase their affirmative self-esteem and more specified performance-centered programs are required toform a harmonious relationship among parties of students. The purpose of this study is to improve an affirmative self-esteern and a desirable personal relationship of children through developing friend-praise program and adapting it to children. Based on the above purpose, the following subjects for this study 'are suggested. Firstly, is the friend-praise program effective in forming an affirmative self-esteem of elementary students? Secondly, is the friend-praise program successful in improving a desirable personal relationship in an elementary school? In addition, two hypotheses of study are decided on the basis of theoretical background and the former study. Hypothesis 1. The friend-praise program will have a meaningful effect on improving an affirmative self-esteem. Hypothesis 2. The friend-praise program will have a meaningful effect on improving a desirable personal relationship. In order to improve the above hypotheses, the experiment was carried out with two classes on the fourth grade in M elementary school in Wonju with being divided into one experimental group and the other comparative group. The friend-praise program which was adapted to the experimental group was composed with four steps as 'introduction', 'preparation', 'operation' and 'closing'. This program which has twelve categories was executed once or twice in a week and each class was continued for forty or sixty minutes. Contrastively, comparative group had no application of the main program. For the purpose of proving the hypotheses after adapting the program to students, I have executed both self-esteem test and personal relationship test. The tests were performed with using SPSS/Windows V10.0 and the statistic was conducted through independant sample t-test for the difference between groups and contrastive sample t-test for the individual difference in each group. The results of this study can be summarized like the followings: Firstly, from the result of previous and after tests, there was no meaningful change in the comparative group, but the experimental group showed meaningful difference in all categories of self-esteem(t=-4.496, p=.000). Especially, the general self-esteem(t=-3.216, p=.003), social self-esteem(t=-2.680, p=.012), homely self-esteem(t=-3.732, p=.001), and school self-esteem(t=-3.902, p=.000) showed a meaningful difference. At the same time, the experimental group also showed meaningful difference with the comparative group in self-esteem(t=-4.758, p=.000). Especially, the general self-esteem(t=2.581, p=.017), social self-esteem(t=3.160, p=.003), homely self-esteem(t=4.283, p=.000), and school self-esteem(t=4.110, p=.000) showed a meaningful difference. As a result of this experiment, the friend-praise program will have a meaningful effect on improving an affirmative self-esteem was proved. Secondly, there was no meaningful change in the comparative group, but the experimental group showed meaningful difference in all categories of personal relationship(t=-4.131, p=.000). Specifically, satisfaction(t=-2.113, p=.045), communication(t=-3.381, p=.002), confidence(t=-3.517, p=.001), intimacy(t=-3.958, p=.000), sensibility(t=-2.955, p=.006), openness(t=-4.318, p=.000) and interest(t=-2.941, p=.000) showed a meaningful difference. In the same instant, the experimental group also showed meaningful difference with the comparative group in all categories of personal relationship(t=3.897, p=.000). Especially, satisfaction(t=2.257, p=.003), communication(t=3.527, p=.001), confidence(t=3.704, p=.001), intimacy(t=3.904, p=.000), sensibility (t=4.382, p=.000), openness(t=2.648, p=.013) and interest(t=2.944, p=.006) showed a meaningful difference. Accordingly, the friend-praise program will have a meaningful effect on improving a desirable personal relationship was proved. Judging from all these results, we should provide primary students with various opportunities to take part in active programs which help them to set up their righteous sense of value, to solve their own problems and to develop their potentials. Consequently, many kinds of practice-centered program like the friend-praise program should be developed more systematically and teachers should apply all those programs to students according to their individual level and developmental stage.

This paper aims to show the various aspects of migration in Kwangju merropolitan area, southwestern Korea, for a period of years 1980-1985. Migratory patterns are spatially extensive in countryside around Kwanfju, and due to high accessibility to the metropolitan area urban implosion emerges in the city. In Chonnam province where Kwangju is loca-ted, all cities and counties except for such in-dustrial areas as Yochon, and Kwangyang are experiencing population losses in terms of net migration by survival rate methods. Kwangju is the exceptionally one of in-migration areas in Chonnam, though its central part(Dong-Gu) is also an out-migrated area. Predominantly in-migration urban areas have high proportions of a student age group between 15-19 years, and that reflects the importance of the educational factor in migration analysis. The municipal authorities of Kwangju are planning to block the way of the middle sxhool students who live in the outskirts of Kwangju to entrance to high school in the city. Thant may stir up migrations into Kwangju for the elementary and middle school students, because the city id expected to provide educational opportunities higher and better than remaining Chonnam areas. Population of Kwangju would, therefore, grow as the students migrate into the city. The findings on the residential intra-city movement in selected 5 Dongs indicate that implications of a short-distance movement re noteworthy; neighbour to neighbour, and the nearest stop in the way from the outer Kwangju as well. Trends in a short-distance movement are in accord with Ravensteins's "law of migra-tion". But in casw of the inter-provincial migra-tion to Kwangju, the number of in-migrants from remoter Seoul is more than that from nearer Chonbuk province. Therefore it supports the fact that the movement between capital region and far off local cities overcomes a distance barrier. The temporary mobility for a day has been increased as the standard of living has improved and it reaches a peak on weekend or on con-secutive holidays. The number of temporal movers to Kwangju from capital region and Yongnam area, southeastern Korea has a greatincrease in terms of the frequency of the passengers' mobility, in particular on Myongjol(the ethnic and traditional festival day) in com-parison with on weekdays. By comparison with two largest Myongjols, the number of movers is more on Chusok(The Full Moon festival on lunar August) than on Sol (lunar new year's day). Annual peak point of weekday movers appears in August because of summer vacation. But the lowest one appears in June, which is related to the busy farming season. A patients' move for medical services in on the increase with a change of living conditions. It is especially true in the industrial counties such as Kwangyang and Yochon. By way of conclusion, it should be pointed out that one of the problems we face in survey of migration volume by the survival rate method is that the survival rate somtimes exceeds the value 1.0, in normal states of which should be under 1.0. it may be due to the shortcoming from the census statistics. We should not give therefore too much stress on the importance of migrations or moves as an element of changes in spatial pattern. In cinclusion, the results of the study show some geographic facts as the followings: 1. One of the outstanding phenomena in all types of movement is the seletivity of ages. The most important factors are related to education and employment. 2. Short-distance movement is carried out in accordance with Ravenstein's law, but in case long-distance movement, in-migration from capital region is prominent in spite of remoten-ces. The gravity between large cities such as Kwangju and Seoul, which has a frequent human movenent, causes urban implosion of small cities between those cities. 3. The temporary mobility for a day, in con-trast to that of permanent movement, is more related to transportation, and its volumes and annual variations are a large-scale. 4. Passengers' mobility is high in industrial cities. And the scope of patients' mobility is narrower than passengers'.

Stow nets have widely been used in the western sea of Korea from the olden age. The original structure of a stow net is a large square-sectional bag net made of 4 netting panels, and the front fringes of top and bottom panels are connected to the top and bottom beams respectively. Wire ropes, which is originated from the holding anchor are gradually forked and biforked, and finally 4 pieces of wire rope (biforked pendants) are jointed to each beam. Much convenience caused by long and heavy beams were problemed, then some studies have been carried out to improve the net since 1930's. The most effective improvement were achieved in 1980 by Mr. Han and his colleagues. The key point of improvement was that the beams were removed and the belt shaped shearing device made by canvas was attached to the side panels, the head rope and ground rope to the front fringe of top and bottom panel, and biforked pendants are joined to the shearing device. Even though this is the epoch-making improvement of a stow net, the further study should be required to find out more effective method. The authors carried out a model experiment on the stow net to determine the vertical and horizontal opening of a net mouth, and also examine the front, top and side-view configuration of the net. The model net was constructed depending on the Similarity Law of Fishing Gear in 1/10 and 1/20 scale and set against to the current at shallow and speedy flowing channel. The vertical and horizontal openings were determined by using scaled bamboo poles, and the configuration was observed by using specially prepared observation platform and underwater observation glass, and also photographed by using specially prepared underwater photographic equipment. The results obtained can be summarized as follows: 1. The opening height and width of the shearing device varied in accordance with the relative length of the biforked pendants. Considering the height and width of shearing device in 6 cases of the arrangement system of biforked pendants, the best result was obtained in the case that the 2nd, 3rd and 4th pendents from the bottom-most was 5%, 9% and 4% longer than that. 2. On the top-view configuration the excessive deformation of head rope and ground rope were observed. In the actual net, 54m long head rope and ground rope were attached to the front fringe of top and bottom panels so that the head rope may be lifted to make the net mouth open highly. But actually the head rope and the ground rope are streamed backward without any lift, and also the netting followed the ropes were deformed until the 2/5 in the whole length of the net. This deformation may be guessed to disturb the entrance of fish school into the net and also caused the net to get caught by obstacles in the sea bed and to be broken largely. 3. Hydrodynamic resistance R of the actual net may be deduced as R(kg)=29.2$\times$103 v1.65. It is also expressed as R(kg)=5.9$\times$d/l$\times$ab v1.65. depending on the formula deduced by Koyama to estimate the resistance of trawl nets, where d/l denote the ratio between diameter of netting twine and length of mesh leg in every part of side panel, a and b, the stretched circumference of the mouth and the stretched length of the net, respectively.

With socioeconomic development and change of esthetic recognition, the demand for orthodontic treatment and number of orthodontic patients has been increasing so rapidly. And frequency of malocclusion was changed. So this study was done in an attempt to provide an epidemiologic study so that we can accomodate their orthodontic needs adequately and to obtain the reliable quantitative information regarding the characteristics of orthodontic patients who visited Department of Orthodontics, Seoul National University Hospital from 1985 to 1994. Following results were obtained. 1. The total number of orthodontic patients of SNUDH during 1990-1994 increased in comparing with that of 1985-1989. And it showed that the number of annual patients was increasing trend. 2. The total number of female patients was 1.59 times as high as that of male. It showed that the annual percentage of female patients has been increasing and that of male patients has been decreasing. So demands for orthodontic treatment of malocclusion of female patients were higher than that of male patients. 3. Each total percentage of class I, class II div.1, class II div. 2 and class III was 35.98%, 14.00%, 1.74% and 48.28%. The annual percentage of class I group had been decreasing but it has increased at 1994. However that of Class III group had been increasing until 1991 but it has been decreasing. 4. Each percentage of less than 6 year-old group, D to 8 year-old group, 8 to 12 year-old group, 12 to 18 year-old group and more than 18 year-old group was 2.65%, 8.63%, 32.50%, 27.74% and 28.48%. Annual percentage of 12 to 18 year-old group ( middle & high school students group ) had been decreasing but it has been increasing. However 18 year-old group had been increasing but it has been decreasing. So entrance examination for college and university is an important factor to distribution of age group.
