In this paper, we verified the effect and appropriateness of the scheme to cure the math. disliking disposition which is the cause of underachievement in learning. We choose 3 schools as the subject of experiment for this research. Each experiment experiment class consists of 27~30 students(underachievers) whose final test results of 1st school year in the middle school are 30~60 points. In this case, we also select some middle level students whose test results are more than 60 points for the normal experimental condition. For this research, we developed the suitable test materials to cure the mathematics disliking disposition of underachievers. We applied those test materials to the experiment schools during 2.5 months and we analysed the variation of disliking disposition, the variation of math. dislike students' number and the cure rate of the math. disliking disposition. From the results of this experimental study, we find that the factors of teacher and math recognition environment have only the significant difference of math. disliking disposition between experiment class and comparison class under the 5% significance level in one middle school. We understand that this results caused by teachers' careful advice and guidance in that middle school. We also find that the number of student who dislike mathematics decreased in two middle schools. Furthermore 50% of math. disliking dispositions are cured for 9 disliking factors in the lower grade group(the group of underachievers) and as a whole, we can see that 50% of cure rate for the 7 factors of math. disliking in two middle schools. So we can understand that the experiment of our research was performed successfully in two middle schools. In this research, we find out that the scheme to cure the disliking dispositions for the factors of math. disliking depends on the factors of teacher who take charge of cure. So teachers must take interest in and must have careful concem to students and their math. disliking.

영남지역(嶺南地域)의 경지정리실태와 경지정리(耕地整理)에 따른 답토양의 이화학적 특성(特性) 변화정도를 알기 위하여 경지정리사업(耕地整理事業)이 실시(1979~1980)된 33개(個) 시군(市郡)의 68개(個) 사업지구에 대한 설문조사(設問調査)와 아울러 1981년도(年度)에 경지정리(耕地整理)를 실시한 29개(個) 시군(市郡)의 37개(個) 사업지구 3,300ha에 대하여 절토답(切土畓)과 무절토답(無切土畓)의 이화학적 특성(特性)과 수량조사(收量調査)를 실시한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 설문조사결과(設問調査結果) 농민(農民)들의 대부분(大部分)이 경지정리(耕地整理)에 의(依)한 기반조성효과를 인정(認定)(70.3%)하고 있으나 경지정리후(耕地整理後)의 지력감퇴(地力減退)(27.2%), 지균작업부충분(地均作業不充分)(60.7%), 농민(農民)의 경비부담과중 및 공기지연(工期遲延)에 의(依)한 이앙지연초내(移秧遲延招來) 등(等)이 문제점(問題点)으로 나타났다. 2. 절토비율(切土比率)은 평탄지(平坦地)에서는 15.3%에 불과(不過)하지만 완경사지(緩傾斜地)나 경사지(傾斜地)에서 각각(各各) 25.9% 및 45%로서 경사도(傾斜度)가 높을수록 절토비율(切土比率)이 증가되었다. 3. 절토지(切土地)는 무절토지(無切土地)에 비(比)하여 경도(硬度) 및 가비중(假比重) 증가, 공극량(孔隙量)과 입단량감소(粒團量減少) 등(等)의 물리성(物理性) 악화(惡化)가 현저(顯著)하였다. 4. 지형별(地形別) 물리성(物理性)의 악화정도(惡化程度)는 홍적태지(洪積台地), 경사지(傾斜地)에서 큰 반면(反面)에 평탄지(平坦地)에서는 적었다. 5. 화학적특성변화는 절토지(切土地)가 무절토지(無切土地)에 비(比)하여 유기물(有機物) 및 유효인산의 함량(含量)이 현저(顯著)히 감소(減少)되었으나 규산(珪酸) 및 석회함량(石灰含量)은 증가되었다. 6. 경지정리답(耕地整理畓)의 절토지(切土地)는 지역내(地域內)의 무절사지(無切士地)에 비(比)하여 수량구성요소(收量構成要素)의 전반적(全般的)인 감소(減少)로 약(約) 28% 감수(減收)되었다. To find out problems and changing soil properties induced by leveling of paddy, a field survey was carried out with questionares to farmers of 68 project areas (990 farmers). The soil characteristics between natural soils and cut out sites was compared with soil samples taken from 37 project areas. More than 70 percents of farmers answered to the questionares expressed satisfaction on the paddy land leveling project; however, some farmers replied dissatisfaction that the arable land was decreased the soil productivity due to loss of surface soil or insufficient surface leveling, that the government support was insufficient and that transplanting of rice might be delayed due to retardation of the project. 1. The rate of cut out soils during the land leveling on plain terrain was about 15.3%, but the rates on gently sloped terrain (2-7% slopes) and sloped terrain (7-15% slopes) were relatively high showing 25.9% and 45%, respectively. 2. The deterioration of physical properties was clear in cut out site where the hardness and bulk density increased and the porosity and the rate of water stable aggregate decreased. 3. The degree of deterioration of physical properties on the Diluvial terrace was more severe than on plains or sloped alluvial fans and valleys. The decrease of available phosphorous and the content of organic matter in the cut out place due to land leveling were prominent. 4. The rice yield from cut site was decreased by 28% comparing with that from natural soils.

The purpose of this study is to recognize, in order to popularize the golf as a university-sports, the relevance between university students` general index(ex. sex, grade, development) and the grade of playing sports, and to illuminate their interesting to the golf and their value to the sports(the value of mental and physical). To realise this purpose, we made investigating sheets that have asked above points. We distributed those to 690(man and woman) the university students in Taegu and we have let them write in the way of self-administration. We got 622 effective samplings. The used program of this material is SPSS 8.0 statistic program. In order to recognize and analyse the relevance between university students` general index(ex. sex, grade, development) and the grade of plying sports, we have used cross-analysis. To their value(mental and physical) to the golf, we have used the Two-way ANOVA. With multiple comparative analysis of Tukey we carried out reproof. According to above process, we had the results, it is followed ; 1. Recognizability of Golf due to the relevance between university students` general index and the grade of playing sports; About the experience of playing golf, the answer `No have been` is in most, and we have quasi-results in the sex, grade, the grad of playing sports, except the development. To the interesting to the golf as a preliminary class, man is higher than woman, junior is higher than freshman and sophomore, we have quasi-result in the sex, grade. To the pupularizability of golf, we have followed result in most, it belongs to the high stratum, women is higher than men, and we have quasi-results in the sex, grade. To the experience to the golf through mass-media, regardless of university students` general index and the grade of playing sports, `Have been` is in most, so it represents the effect of mass-media, we have no quasi-results in this points. To the ratio of strength-consumption, in comparative to other sports, `Less` is more in man than in woman, in freshman is more than in junior. We have quasi-results in the sex, grade. 2. Valuability of Golf due the relevance between university students` general index and the grade of playing sports. To the psyco-value in sex and grade, `More` is represented in the woman as freshman and sophomore, in the man as junior and senior, we have quasi-results in the sex, grade. But, psyco-value and physical-value in sex, development, grade and the grade of playing sports, we don`t have quasi-results. In sum, the indirect experience to the golf is very high, but the direct experience is very low in Korean university students. Until now, they think , playing the golf is belonged to the high stratum, the interesting ratio is very high. So in order to popularize the golf, it is more need that, illuminating the superiority of golf in psyco-value and physical-value and expending the direct experience through the physical class in the university are more useful than simple and indirect experience through mass-media.
