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.

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

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.

The effect of the rate of strain on the shear strength has been studied mainly in clay and sands. This paper is designed to establish the effect of the rate of strain by the triaxial compression test on weathered granite soil samples which vary in moisture content. The major results obtained from this study were: 1) Increasing strain rate increases angle of shear resistance but the cohesion decreases, 2) The variation of strength parameter is smaller under the 1.0-1.25mm/min rate of strain than any other strain rate, 3) The shear strength of weathered granite soil increases as strain rate increases.

This paper tries to newly call love songs between male and female in Jo-seon Dynasty <Yeon-jeong-ga-sa>, in contrast to the conventional definition, namely <Ae-jeong-ga-sa>. In addition, it aims to investigate the background of formation of these songs. Until now, there has been a strong assumption that these kind of songs had been written in late Dynasty, in that there has been not nearly made love songs because the Jo-seon Dynasty adopted Confucianism as a common moral and a political philosophy. However, I found that there have been 71 love songs through investigating the related books and materials which have been still available. On the basis of above discussions, I categorized the formation backgrond of <Yeon-jeong-ga-sa> in both early and late Jo-seon into two types. While I dealt with the general trend, that is open description of sex, in literature and art in the perspective of outside influences, I did the method of creation and narration in early love songs, and progressive emotion of female writers in the view of inside impact. Particularly, regarding the inside impact, I confirmed that <Yeon-jeong-ga-sa> was much influenced by the skill of praise in the <Mi-in-byeol-gok>, the recognization of feminism in the <Won-bu-sa> and the method of narration in the <Sa-mi-in-gok> and the <Sok-mu-in-gok>.

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.
