Underground flexible pipes for electric cables are subject to external loads and surrounding soil pressure. Particularly, strain of flexible pipes is of great concern in terms of safety and maintenance of electric cables. In this paper, stress and strain of flexible pipes with two types of installation gap, ie, l0cm and naught, were compared to investigate the structural integrity of pipes from actual field test. The effect of degree of compaction and burial depth were also investigated to simulate the variety of construction situation. The results of the field test show that the strain criteria were satisfied under the burial depths of 80cm, 100cm and 120cm regardless of installation gap.

Many researchers and librarians in library and information science area in Korea and Japan claim that Japanese Hongdohoe Library is the first modern public library in Korea. The results of analysis of the study reveal that the claim should be reconsidered because of the following reasons. Firstly, Hongdohoe Library was established in Korea but was established by Japanese. Secondly, the library was established for Japanese in Busan and operated for a long time for the use of Japanese people in Busan. Thirdly, most of the collection of the library were revealed as Japanese materials. Fourthly, the Japanese Hongdohoe which established the library was the organization that supported Japanese militarism before and during the Japanese occupation of Korea.

The purpose of this study is to investigate the influential factors creating the modern library thought in the latter part of Yi Dynasty. After Korea was forced to make a treaty opening up the country in 1876, Western civilization was introduced and reforms were carried out eventually. Various influential factors could be taken into consideration as follows. (1) The envoys to Japan after 1876 (2) Tourists party to Japan organized by Gentlemen in 1982 (3) The persons who studied abroad (4) Establishment of modern schools and development of publications: on the new learning. (5) News media and others Above all, the persons who studied abroad, such as Yu Gil Jun, Yun Chi Ho, etc., in early stage has contributed most to the extension of public recognition for modern library in Korea. Therefore it can be said that the formation of modern library thought in Korea was based on the theory of the Western library as was the Japan in the period of Meiji Restoration. Patriotic intelectualls in these days believed that reform of the educational system and the diffusion of knowledge was very much meeded in order to preserve an independent Korea and to build up national strength, and then nation-wide campaign for enlightenment was earried on. For that reason the movement of the national library establishment in 1906 also should be regarded from the same point of view, that is, as a part of the enlightenment campaign. Therefore it should not go unheeded that strong patriotism was always streamed under the ground of the library campaign as well as the new learning and new education campaign. Unfortunately every plan of Korean library movement had broken down and missed the chance for having experience of self-development because of the Japanese invasion.

The purpose of this study is to examine how Korean changed and applied the railway official residence space constructed by the Japanese, when they occupied these railway official residence space after liberation from Japan, and specify the relationship between the life culture and residence space by analysing the differance in important life style, as well as element of change in important residence spaces according to modernization. In addition, this study was carried out by means of research on the form and pattern, visual anthropological method by photograph and direct observation.The result of this study is summarized as fellows. The residence space at Kyounaju constructed by the Japanese on the basis of the culture has been changed and applied to the life style of the Korean when the Korean occupied these Japanese style residence space.Then, it seems that the change of the Japanese style residence was caused by both differance in the life pattern between Korea and Japan, and the medernization of the life.

This study inquired into the significance and the Process of development of military library being recently issued as a movement to establish a library In the military units in Korea, focusing on the library management of military in the United States. Firstly, the history of military libraries in the United States and military library service of the U.S. Armed Forces during the Korea War was investigated and analyzed. And, the establishing status, organization, and the contents of library service program in the United States was researched.

본 논문에서는 영상기반 모델링에서 3차원의 기하학적 제약을 이용한 모델링을 다루고 있다. 기존에 이러한 연구가 많이 진행되어져 왔으나, 여기에서는 새로운 방법에 의한 모델링을 시도하였다. 이러한 접근방법은 이해하기가 쉽고, 편리하며, 간단한 모델링에 적용이 용이하다. 또한, 영상평면 정보와 3차원의 정보를 가지고 있기 때문에 기존의 3차원 복원 이론과 혼합하여 적용할 수 있다. 영상기반 모델링(IBM, Image Based Modeling)의 핵심은 2차원 영상에서 사라진 깊이 정보를 어떻게 찾는가에 있다. 기존에는 3차원 복원을 위하여 투영된 영상평면의 점을 이용하거나, 이미지 상에서의 소실점을 찾거나, 2차원의 벡터와 3차원의 공간 좌표의 특정한 평면에 놓여있는 벡터와의 관계를 이용하여 깊이 정보를 복원하였다. 이러한 접근 방법은 사용자가 선택한 2차원 좌표로부터 3차원 좌표를 구하는 것이다. 본 논문에서는 기존의 방법과 다르게 3차원 원시 기하모델의 제약을 이용하여 사용자가 3차원 원시 기하모델을 2차원 영상에 투영하고, 그 정보를 이용하여 영상의 3차원 정보를 찾아 나가는 방법을 소개한다. 또한, 선형적인 최적화 기능을 넣어 관사 모델을 구하였다.

$\varepsilon$-SVR(e-Support Vector Regression)학습방법은 SV(Support Vector)들을 이용하여 함수 근사(Regression)하는 방법으로 최근 주목받고 있는 기법이다. SVM(SV machine)의 한 가지 방법으로, 신경망을 기반으로 한 다른 알고리즘들이 학습과정에서 지역적 최적해로 수렴하는 등의 문제를 한계로 갖는데 반해, 이러한 구조들을 대체할 수 있는 학습방법으로 사용될 수 있다. 일반적인 $\varepsilon$-SVR에서는 학습 데이터와 관사 함수 f사이에 허용 가능한 에러범위 $\varepsilon$값이 학습하기 전에 정해진다. 그러나 Nu-SVR(ν-version SVR)학습방법은 학습의 결과로 최적화 된 $\varepsilon$값을 얻을 수 있다. 정해진 기저함수가 포함되는 $\varepsilon$-SVR 학습방법(Sermparametric SVR)은 정해진 독립 기저함수를 사용하여 함수를 근사하는 방법으로, 일반적인 $\varepsilon$-SVR 학습방범에 비해 우수한 결과를 나타내는 것이 성공적으로 입증된 바 있다. 이에 따라, 본 논문에서는 정해진 기저함수가 포함된 ν-SVR 학습 방법을 제안하고, 이에 대한 수식을 유도하였다. 그리고, 모의 실험을 통하여 제안된 Sermparametric ν-SVR 학습 방법의 적용 가능성을 알아보았다.

In this paper, we propose a new blind image watermarking method in wavelet domain. It is necessary to find out watermark insertion location in blind watermark. To select the watermark embedding locations, we use the increment and decrement information of the successive approximation coefficients after discrete wavelet transformed. In order to evaluate the proposed algorithm we embed watermark into test images and detect the watermark after attacks like JPEG lossy compression and performing of various liters. Experimental results show that the proposed method is robust against various kinds of attacks and still remains transparency.
