Recently, many techniques have been developed for efficient transmission of MPEG Video and improvement of quality of service. In this paper, we propose fixed bit rate control algorithm using neural network which protects the overflow and under flow of buffer in order to maximize the channel utilization and the picture quality of the reconstruction image. The proposed controller consists of three-layered fully connected neural network with 16 input, 6 hidden and 3 output nodes using Back Propagation algorithm. The performance of efficient and adaptive control algorithm is evaluated and compared to TM1, MPEG Ⅱ in terms of PSNR, BPP(Bit Per Pixel), BPF(Bit Per Frame), average quantizer scale factor. The results are shown that proposed method is superior to TM1 about 0.5 dB(PSNR) for Table-Tennis, 0.2 dB(PSNR) for Football images.

Even though STD test based on Terzaghi's 1-D consolidation theory is extensively used to estimate the consolidation constant of soft-clay, it takes too much time to perform the test in addition to the problem in estimation of C_v and preconsolidation pressure. To overcome these defects, several types of rapid consolidation test, e.g., Constant Rate of Strain Test (CRS) and Controlled Gradient (CG), are proposed. Because consolidation characteristics obtained from the results of CRS test depend on the rate of rate of strain, it is repuired to determine the variation rate on the basis of the physical and structural characteristic in a building site, and then perform the test. Several methods determining the rate of strain, e.g., ASTM standard, Smith and Wahls' equation in 1969 and Armour and Drnevich's equation in 1986, have been researched. However, the rules about consolidation rates described in ASTM consider only the summary of the rate rules as a trial and error and its criterion also depends only on LL value. In this thesis, the test rate and parameters related in addition to LL value considered on ASTM basis are esamined in many fidlds of view ane the corresponding rate criterion is proposed.

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.

해방신학의 이해와 비판

김팔곤 圓光大學校 1985 論文集 Vol.19 No.1

According to the meaning of "liberation" which is taken in theology of liberation, the realm of theology of liberation is enlarged or cut down. If "liberation" is reg-arded as all kinds of endeavous to leberate people from poverties, pains and oppre-ssions, the realm of theology of liberation shall be enlarged, and most social thou-ghts in Christian theology are included in it. But the conception of "theology of liberation", ususally used in these days, was resulted from certaion objects in certain regions. "Theology of liberation" dealt with in this thesis is that which has been resulted from the background of Latin America. Lately, in Korea, arguments about ideoloigical problems have been suggested activ-ely, and accordingly discussions about theology of liberation have come about largely. But studies on theology of liberation have not come to profund depths yet in Korea. In this thasis I have tried to look for clues toward more profund studies. In 1st chapter the historical and social backgrounds of theology of liberation are outlined. In 2nd chapter the methodology of theology of liberation is outlined and criticized. In 3rd chapter the subject matters of theology of liberation are outlined and criticized.

敎師와 學生의 關係別로 본 記憶에 남는 훌륭한 敎師像

尹八重 全北大學校 1969 論文集 Vol.11 No.-

This research attempts to answer the following questions. (1)What are the general characteristics of high school teachers remembered and respected by their students? (2) What are the corelations of characteristics between well-liked teachers and the students who like them? (3) What acts or situations involving these well-liked teachers are most memorable to their students? These questions are transformed into hypotheses which are tested using numerical data from questonaire responses of 295 freshmen (45.5% of the whole population) at Jeonpuk National University. The results can be summarized as follows. (1) The respected teacher's methods of class control are not statistically significantly related to his age, qualification etc. (2) There are statistically significant relationshtp between the well-respected teacher's sex, major, etc. and those of the students who like him. The results of the present research give some valuable suggestioms for teacher training institutions. They are: (1) All types of teacher training institutions must emphazise liberal education. (2) In-service education must be open to all teachers. (3) Male teachers should teach male students; female teachers should teach female students. (4) Classroom teachers must be changed frequenly. (5) Gymnasiums and special rooms must be used more often in autumn. (6)Teacher training institutions must have speech training courses in their curricula.

戀情歌辭 <僧歌>의 實相 考察

김팔남 한국어문학회 2003 語文學 Vol.0 No.81

<Seung-ga> is a type of the love song that a Buddhist nun makes Questions and answers with a man. Since there are still some discussions whether the <Seung-ga> was a non-fiction story, my work aims to confirm that the <Seung-ga> is a real story and to point out who was the author and when it was written, based mainly on the『Chu-je-jeep』 written by Jo Su-sam. The main findings of my work are summarized as follows. Firstly, I suggest that authors were both 'Nam Cheal' who belonged the upper class and 'Ok Sean' who was a Buddhist nun. Secondly, I guess that the <Seung-ga> was made in around 1723. In addition, I found that the <Seung-ga> was very popular in that time so that it was recorded very frequently and continuously in『ga-sa-jeep』, the music collection book.

紫霞詩의 淵源 硏究

Shin Wi (pen name: Jaha, 1769-1845) was one of the greatest 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 both at home and abroad. Jaha was a prolific poet who left about four thousand pieces of verse behind him. His representative works are thirty-five piece Verses Commenting upon Korean Poets in which Chinese poems written by Koreans were evaluated in the form of verse, forty piece Soakbu in which Korean sijos were translated into Chinese, fifty piece Sundry Poems which has been favorably compared with Po Chu-i's (772-846) 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 documents on the dramas and actors of his days. This author has been involved in Jaha for years, reading through his writings and publishing some successive studies on him. In "A Study of Shin Wi's Soarbu" (Collected Treatises, Busan Women's Univ., Vol. 7, Feb., 1978) my attempt was a study of his writings, and his creativity and origins were treated in "An Analytic Study of Dongin Nonsi Jeolgu" (Suryeon Studies of Korean Language and Literature, Busan Women's Univ., Vol. 6, Dec., 1979). In addition, "A Study of Shin Jaha's Writings" on which this study is also based had already been published in Collected Treatises, Busan Women's Univ., Vol.5, 1977. These studies were, however, rather superficial since the world of Jaha's writings was too wide and his knowledge of poetry was too deep for this author to cover thoroughly. "Jaha was much indebted to his master, Su Shih (1036-1101), and also influenced by Hsu Ling (507-583), Wang wei (699-762) and Lu Yu (1125-1210)," remarked Kim Taek-yeong (1850-1927) in the preface to Collected Poems of Shin Jaha, but Jaha's covered even Shin Ching and the works of Chu Yuan and Sung Yu as well as those who were masters during the periods of Han, Wei and Six Dynasties. Moreover, hewas familiar with the writings of such Chinese Poets as Tu Fu, Wang Wei, Li Po, and Po Chu-of the Tang Period; Su Shih, Huang Ting-chien and Lu Yu of the Sung Period; Yuan Hao-wen of the Chin Period; and Wang Shih-chen of the Ching Period. Thus, it is almost impossible to make a thorough study of Jaha without knowing those Chinese poets who influenced him. Keeping this in mind the present author tried to find out about chiefly Li Po, Tu Fu, Po Chu-i, Yuan Hao-wen and Wang Shih-chen. About the other poets this author is planning to study further in future. The first part of this paper is concerned with the life of Jaha as a poet. The ideological background of his age is sketched, and his family tree is traced up on the basis of the genealogy of the Pyeongsan Shins. After this his literary life is examined more concretely through YijoSillok (the History of the Yi Dynasty), Jaha's Chronological Record edited by Kim Taek-yeong and sixteen-volume Gyeongsudang Complete Works. His association with contemporary important figures home and abroad is also examined for the better understanding of his literary position at that time. The second part deals with Jaha's literary origins. It is carefully examined how he was influenced by Chinese poets, begining with Su Shih who gave him the greatest influence and including Tu Fu, Yuan Hao-wen, and Wang Shih-chen. Some other Chinese poets who are thought to have influenced him are also included at the end of this part. As a conclusion of this study, this author finally evaluates Jaha's literary characteristics and his influence upon contemporary and subsequent classical poets, locating his standing in the history of Korean literature.

The purposes of this paper are to point out a method of using finite difference to solve one-dimensional consolidation problems more realistically, to compare finite difference and classical analysis and to apply the finite difference method to some actual problems. The results obtained from the new scheme were in good agreement with the measured values of a trial embankment constructed on the alluvium of four-layered soils, and a comparison of the settlement predictions indicates that the new scheme is found to be superior to on other scheme.
