It has been known that the shear strength of soil is an important design parameter for the foundation of structures, the retaining walls, the slope failures and so forth. In this study, the shear test was performed by using the direct shear apparatus under various degree of the moisture content and the density of the sample soils. The results of the study were summarized as follows; 1. The shear strength of soil increased with increase in the dry density of soil, and at the same level of density of the sample the shear strength of soil showed large values on a good grading of the sample. 2. The cohesion of the soil varied directly with the dry density of it, however the internal friction angle of soil was not affected by the dry density of the sample. 3. The shear strength of sample varied inversly with the moisture content of it, and this phenomenon was apparent on a good grading of sample. 4. The cohesion of soil showed maximum value when the moisture content of the soil reached optimum level and the internal friction angle decreased with increase in the moisture content of it. These phenomena were very obvious on a good grading sample, SDC-1. 5. The cohesion of the soil decreased with increase in void ratio of the sample, but the internal friction angle of the sample didn't show such tendency.

The paper describes the comparison between observed and predicted stress-strain characteristics of marine silty clay in Dangjin district. For prediction, the hyperbolic model which is applied the parameters acquiring by physical and triaxial compression test was adopted, and the obtained results were summarized as follows: 1. The Young's modulus were increased with decreasing of moisture contents and increasing of dry density. 2. The most affective factor to hyperbolic model is lateral stress and dry density. and than cohesion and internal friction angle. 3. The comparision between the statistical and hyperbolic values of maximum deviator stress have few accordance. and the statisticals is lower than the hyperbolics. 4. Without. much labor and tiresome procedures, effective computer program was made and applied, but technical procedure for prevents test errors of parameter calculation is importants.

Hemingway의 作品에 나타난 作家의 不敗精神과 汎愛精神의 硏究 : The old man and the sea를 中心으로

趙聖燮 圓光大學校大學院 1981 學位論叢 Vol.6-1 No.-

In this thesis, I have tried to view Hemingway and his works. I have especially, concentrated on one of his later novels. He wrote the old man and the sea on the basis of his personal experences. We can see symbolism, self-confidence and strong individualism especially throughout this novel. He concentrated on the team spirit of baseball and team sport ingeneral was symbolic of man's interdependences the main theme of this novel. Hemingway elevated human philosophy to the level of religion and did not deny god, but his god was neither in inner god nor on absolute one. He did not think that religion was absolute, Hemingway had been increasingly concerned with the relationship between individualism and interdependence. THe old man and the sea is the culminating expression of this concern in its reflection of Hemingway's mature view of the tragic irony of man's fate.

In order to investigate the strength characteristics of weathered granite soils in unsaturated state, the five physically different weathered granite soils and the common soil(sandy loam) were examined. The disturbed and the undisturbed material were prepared for triaxial compression test. The following conclusions were drawn from the study; 1. Dry density of the undisturbed soil samples was lower than maximum dry density determined from the compaction test and it showed the higher value at the well graded soil. 2. The failure strength of the samples decreased with the increase of moisture content of the soil and these results were highly pronounced at the common soil sample having a brood cohesive property. 3. On weathered granite soils, the cohesion was lower measured and the internal friction angle highly, the decrease rate of internal friction angle with increase of moisture content of the soil was more significant than that of cohesion 4. The modulus of deformation of the samples decreased with increase of moisture content of the soil and these phenomena were highly pronounced at the weathered granite soils than common soil. 5. The failure strength of the samples increased with increase of confining pressure and effect confining pressure on failure strength was highly significant at the lower moisture content of soil.

To design the safe and rational rock slope, several rock slopes of roads in Kang-won area were analyzed, and the following results were obtained ; 1. The results were analyzed by stereographic projection at the rock slope that the joint was developed. All of the sloped which were designed by standard slope of rock was not considered that the joints were unstable. 2. The relation of rainfall and slope failure, as well as the danger of failure, was very high when the maximum hourly rainfall was larger than 20mm and when there was a 2-day cumulative rainfall that was larger than 200mm. 3. In the design of rock slope, operated by the stereographic projection considering discontinuity. If turn out unstable, it should be analyzed carefully using the limit equilibrium method. 4. In the design of rock slope, it is desirable to consider the discontinuity of rock(joint, bedding, fault).

Scant of our country's cultivated field area scale in case of the works of readjustment of arable lands which are performing positively on the economic development plan, and efficiency and method of readjustment of arable lands which are performing up to the present, are as follows. 1. The area of readjusted arable lands which is 177,279hectares, becomes 9.1 percent of our country's paddy field. But disposal of exchange land which is the accomplished part of this project, is slack with 25.3 percent of the worked area since 1955. 2. Our country's cultivated field area per a farm-house is zero point nine o seven(0.907) hectares, the proportion of the number of farm-house within one hectare is 67.6 percent. the number of farm-houses within one hectare is 67.6 percent, the number of blocks is on an average, five point eight, and the greater part of those is farther apart than 500 meters, consequently these show us scantiness. 3. Readjustment of arable lands prompts to diminish the number of blocks with 34 percent, and to reduce 3.2 personal labours for 10 ares. It makes the cultivated lands two-crops in 78 percent with 28.8 percent increased yield as well as getting land-price increased with twenty three percent. 4. Working expenses invested have a differences between 9,005 won per 10 area under 50 hectares and 6,411 won per 10 areas for 150 hectares and more. Also it increases with 30 percent annually-3,795 won in 1954, 5,464 won in 1955, 7,731 won in 1956, 11,459 won in 1957. 5. Farmers must be enlightened and directed contents and effects of this poroject in order to drive voluntarily. 6. The number of engineers engaging in the project must be increased and educated thoroughly so as to be smooth. 7. Priority in the selection of a works district is given to the most economical flat-field. 8. A man had better perform both an investigated survey and a fixed surv-ey. so that expense and time are saved. 9. Disposal of exchange land have to perform in next year immediately after the accomplishment of execution certainly. 10. Financial resource of working expenses must increase a government subsidy and decrease a local charge simultaneously, and all executive authorities being followed by security of economic resources must be transferred must to the bureau office of supervising project so as to be smooth.
