A convenient means of the determination of the soil properties would be to correlate it with the result of field test such as the cone penetration. But It is difficult to correct evaluation for the soil properties by the only one test at the reclaimed coastal region. In this study, the cone penentration test and seismic wave exploration are performed at the reclamed coastal regione which has the soil layers to be analyzed and the dynamic soil properties. The results obtained from this study were summarized as follows; 1) As a result of field test, the study area was found to be 3 layers. 1st layer was filled in the ground to the depth of 2∼3m and the next layer was showed the soft clay layer to 40∼45m from reclaimed layer. 3rd layer proved to be a bedrock. 2) When the cone penetration test, the cone resistance was observed very great value in the ground to the depth of 0.7m due to the result of ground compaction with the traffic load and consolidation in the nature etc. 3) As the result of study, it presented that the correlation between the cone resistance and the seismic wave velocity is distributed the only a certain range with a group. The correlation between the cone resistance and the seismic wave velocity is determined through the regression analysis. The correlation is assumed a line relationship between the cone penetration resistance and the seismic wave velocity. 4) The method of using the empirical correlations between the cone penetration test and seismic wave exploration is an effective method by which the soil properties can be decided simply. This method has limitations in application because its research and application is in the early stage. In considering the proper engineering factors, however, it can be used efficiently in ground investigation and design.

Korea enters a new era of industrial modernization, spurred by her successive five-year economic development plans. The labor-intensive light industry that led the nation's economy in the past decades is undergoing a gradual shift to the technology-intensive heavy and chemical industry. The demand for industry-minded young technician is thereby ever mounting in number in various industrial sectors, which in turn creates many challenging issues on Civil Engineering Education. Among them, this paper deals exclusively with the curriculum of the Department of Civil Engineering Education. As the results of a trade analysis for graduates from technical high schools, it was realized that current curriculum were somewhat isolated from outside environment and found too rigid to meet the changing requirements. Needless to mention, teachers play a vital roles in the technician education. Accordingly the teacher must be qualified well not only in knowledge on the major subjects but also in practices. The improvement of current curriculum is strongly recommended to produce qualified teachers, taking into account the changing social demands. This study is very limited in terms of finance, time allowance and manpower. Accordingly the model curriculum was based on the trade analysis, social requirements and the current curriculum, and its justification was not verified by tests and broad reviews.

申紫霞의 小樂府 硏究

孫八洲 新羅大學校 1978 論文集 Vol.6 No.-

Shin Wi (pen name: Ja-ha, 1769∼1845) was one of the 'master poets' who wrote their poems in Chinese during the five hundred year period of the Yi Dynasty. He was also an outstanding calligraphist and painter. In the preface to Collected Poems of Shin Ja-ha, Kim Taek-yeong, the editor, says of the origin and characteristic features of Jaha's poetry as follows: Su Shih (1036∼1101) was the poet's master. He was also indebted to Hsu Ling (1507∼1583), Wang Wei(1699∼762) and Lu Yu(1125∼1210). At times rapid, rugged and full of fantasy, his poems soon displays their fine, simple and flat qualities. They employ a thousand feelings and natural aspects so that the reader is dazzled and intoxicated by the brilliant arrangement of dancing words. Indeed the poet was the greatest master of everlasting ages that was ever soaring with the wings of a rare genius. Jaha left about four thousand pieces of verse behind him. among the representative works are forty piece Sookbu in which Korean sijos were translated into Chinese, thirty-five piece Verses Commenting upon Korean Poets in which Chinese poems written by Koreans were evaluated in the form of verse, fifty piece Sundry Poems which has been favorably compared with Po Chu-i's (77 2∼846) 'New yueh-fu', twenty piece Post Chiu rhyu Poems, an imitation of Wang Shih-chen's (1634∼1711) work in the same title, and twelve piece Gwangeuk-jeolgu, a valuable document on the drama and actors of his days. In Collected Treaties Commemorating Dr. Kim Jong-wo's Sixtieth Birthday (Feb. 1977) is carried "A Study of Jaha's Soakbu" by the present author. The study was based on the twenty-three pieces of Soakbu included in Kim Taek-yeong's Collected Poems. Recently, this author had the fortune of obtaining sixteen-volume Gyeongdang Complete Works that contained the complete forty pieces of Soakbu. This paper deals with all the forty pieces in Vomume X, examining them in matters of form and content and analyzing the theories behind the poet's translation of sijos.

Last year a thesis entitled "The Understanding and Criticism of Theology of Liberation" was published in 'Theses Colleetion Vol. XIX' edited by Won kwang University. In that thesis I had tried to outline and criticize the subject matters of theology of liberation. In this thesis, therefore, I need not explain the subject contained in that volume, but try to suggest an alternative theory of theology of liberation. In 1st chapter the ideal background of theology of liberation is outlined. In 2nd chapter the ideal characteristics of theology of liberation are described. In 3rd chapter I try to develope the alternative theory surmounting the weak point of theology of liberation, on the basis of the standpoint of the Christian Realism.

農業部門 投資事業의 經濟的 效果分析의 規準設定에 관한 硏究

文八龍 건국대학교 1979 學術誌 Vol.23 No.1

The objective in undertaking a public investment is, in broad sense, to increase social welfare. Where investment resources are as limited as in the agricultural sector in Korea, it is of the greatest importance to establish "investment criteria" to make correct choices among alternative investment opportunities in accordance with this objective. It is generally accepted that social welfare is a function off number of variables which include economic efficiency, the distribution of income, regional development, and national defense, etc. It is ideal that one would design a model which would predict the effect of each investment project on these variables and obtain a complete ranking of the alternatives. In practice this ideal is seldom attainable, and the economic analyist should be content to present an incomplete display of the effects of each investment project on the important variables, leaving the problem of weighing the various consequences to policy decision maker. There is, however, a class of agricultural investments where economic efficiency may be assumed to be the primary objective, and for most agricultural programs the problem of choosing between alternative investments may be so structured that the choice can be made on the basis of efficiency criteria. Where increased economic efficiency is the primary objective, benefit cost analysis can be used to obtain a ranking of alternative investments. This paper outlines in chapter II the general framework of benefit cost analysis and gives the underlying rationale behind the procedure. If the objective of economic analysis of agricultural projects is to compare benefits with costs to determine which among alternative is more remunerative, then the costs and benefits have to be identified. In chapter III, the nature and the desired measure of benefits and costs are discussed. The treatment of identifying costs and benefits is directed toward practical, operating approaches to the appraisal of agricultural projects. Chapter IV discusses the problem of valueing costs and benefits. There have been controversies over wether current market prices correspond to the true social values in measuring the erects of public investments. It is a general concensus that market prices cannot be applied as a yardstick of true social value when the market functions imperfectly. In chapter V the various problems pertaining to determination of discount rate are discussed. One of the central problems in benefit cost analysis is how to make commensurable the values of benefits and coats which occur at different tines. Also three indicators of investment efficiency are explained: they are (1) benefit cost ratio, (2) net present worth, and to (3) the internal rate of return. Each of these indicators has merits and demerits depending on the purpose of its application and the nature of the investment to which it is applied. Finally, in chapter VI two case studies have been made on the irrigation projects : Taean pumping station project and Jongan reservoir project. On the basis of available data, various irrigation effects are measured, touch as the creation of farmland basis, changes in cropping pattern, increase in yield per hectare, and increase in labor productivity. Also the internal rate of return was computed for each project.

원호 해석법을 적용한 점성토사면의 3차원 해석에 관한 연구

Soil is one of the material that have been used for civil engineering. Soil slope is constructed unavoidably because fill and cut is repeated during construction. If most of structure is destroyed, it causes great loss of life and economic loss. Especially, the stability of soil slope is very important because most of structure has a soil slope. However, Though a study about stability of soil slope has been advanced, soil slope is being destroyed continuously. In fact, a precise analysis of slope failure is impossible because, slope failure has a very complicated and combined mechanical relation. So, many scholars and civil engineers have analyzed a stability of slope by 2-D plane on the basis of plane-strain condition. It means that failure of slope occurs equally on any section of soil slope but, very important fact is failures have a finite width and shape of failure and mechanical relations are different for location of section. Therefore, 3-D spatial idea must be introduced to modeling for probable analysis of slope stability. In this study, an assumption that failure block is a part of sperical shape which has an arbitrary center point and radius is introduced and the computer program, 3DSSA(3-Dimensional Slope Stability Analyzer), is developed on the basis of the circular arc method(∮=0 method). For using 3DSSA, the chart of 3-D stability number is made for many geometrical conditions of cohesive soil slope that pore water pressure is not considered. Through the analysis of finite simple cohesive soil slope, the results obtained by means of the computer program 3DSSA show that: 3-D factor of safety is 1.41 times larger than 2-D factor of safety for most case of soil slope. 3-D stability number converges at 0.128 as angle of slope increase from 7.5。 to 60。. When angle of slope is 60。, 2-D stability number calculated by 3DSSA is smaller than Taylor's(1948) by 5.6 percent. The changes of cohesion and unit weight of soil affect little the ratio of 3-D factor of safety to 2-D factor of safety.
