The purpose of this study is on the application of the facade design of k-national university in deagu. The subjects of the study examined 75 buildings from the 117 university buildings in main campus. The analysis items is analyzed by several elements; flat and sloping roof, main entrance, design principle, style of architecture, finishing materials, and characteristics of design surveyed by analysis items. The results are as follows: In the 1950s, 2 subjects have shown conflicting characteristics except brick finishing materials. In he 1960s, flat make up 75% of a whole, centrality in main entrances occur, but have an asymmetrical, during this period vertical motif have been underlined by repetition of column, stone has application to main adminstration building. The buildings in the 1970s were so characteristics of modern architecture by painting and flat except main entrance at the center of facade. In the 1980s, position of main entrance have a corner of a wall, finishing materials of a wall were beginning to use stone, glass and metal. The buildings in the 1990s and 2000s are looking a three-dimensional composition by rhythm of superimposition and segmentation and all finishing materials of analysis items are in use.

This paper focuses on the sports look expressed in 20th century fashion. It is Age of Sport just as rock'n roll became dominant cultural form of the 1960's and 1970's . In the 1990's the sportsware is fashion. Designers gazing into the future are inspired by the details and functionality of clothing for snow boarding , skiing , motorbike racing and fitness. No doubt fashion in 2000 will also be full of references to it. Since the late 1960's the sportswear that was originally a term for clothing worn for various sports activities in the 1890's has changed and is now considered as fashion for day as well as evening. This has occurred primarily in the U.S. due to the adoption of less formal lifestyles by Americans. while the sportwear is the term which stemmed from the need for functionality in sports, sports look is the style inspired by the formative elements, that is, the details, the shilhouette, and the colors of the sportswear. New technologies for sports, the powerful influence of youthful culture, and the celebritizations of the sports stars made the sports look much hipper and more popular. It can be categoried into three aesthetic values, I. e., the functional sports look,, purism and no useless ornament, the street sports look with fun, androgynous and unisex mode and the mix and match of different texture and colors, and the futuristic sports look with new high tech fabrics and avant-garde style.

The purpose of this study is to provide a basic for a desirable bathroom plan of apartments. As a first step in this process, we analyzed the bathroom plans of the apartments(area: 10-69 pyung) constructed in 8 sections in Seoul from 1971 to 1995 where 65,801 households live. In this study, the numbers, location, size, and proportion of the bathroom and dressing room, and the direction of the bathroom door in apartments are examined. The major frindings are as follows; 1) We have found that the numbers of bathrooms to increase in more than 20s pyung apartment since 1990. 2) Except a master bathroom, the another one for the guest is located in enterance in more than 40s pyung apartment. 3) The door of the bathroom faces corridor in more than 40s pyung apartment. So, it is possible for them to lessen discomfortness when they coming in and out of the bathroom. 4) It was found that the size of bathroom were decreased in most cases. 5) They did not plan a dressing room in 10s pyung - 60s pyung and the size of dressing room was decreased in 60s pyung apartment.

This paper aims to analyze inequality of maize self-sufficiency rate among countries in 1970-2011. Utilizing sub-group consistency of Generalized Entropy and Atkinson inequality index, the estimated maize self-sufficiency rate inequality is further decomposed into two steps' separate country groups. First, lower and upper income groups and then lower, lower middle, upper middle and high income groups are used based on the national classification of the world bank. It is inferred that 1980s' policy intervention and 1990s' Uruguay Round negotiations have different effect on the inequality among four different country groups.

This study compared the roundwood demand prediction accuracy of econometric and time-series models using Korean data. The roundwood was divided into softwood and hardwood by species. The econometric model of roundwood demand was specified with four explanatory variables; own price, substitute price, gross domestic product, dummy. The time-series model was specified with lagged endogenous variable. The dummy variable reflected the abrupt decrease in roundwood demand in the late 1990's in the case of softwood roundwood, and the boom of plywood export in the late 1970's in the case of hardwood roundwood. On the other hand, the prediction accuracy was estimated on the basis of Residual Mean Square Errors(RMSE). The results showed that the softwood roundwood demand prediction can be performed more accurately by econometric model than by time-series model. However, the hardwood roundwood demand prediction accuracy was similar in the case of using econometric and time-series model.

지난 세기말까지는 통신의 주된 기능이 음성 전달에 머물렀지만 금세기에 들어와서는 동영상을 위시한 다양한 정보들이 생산되고 유통되며 소비되고 있다. 데이터 트래픽은 음성 트래픽을 오래 전에 추월하고도 매년 기세가 꺾일 줄 모르고 기하급수적으로 증가 중이다. 이러한 정보화 시대를 뒷받침하는 여러 요소가 있으나 광전송 기술의 공로도 결코 작은 것이 아니며 앞으로도 누구나 최소한의 비용으로 무한한 정보를 생산하고 유통하며 향유하는데 선도적 역할을 할 것이다. 돌이켜보면 1960년대에 유리로 된 광섬유를 통해 신호를 전송하는 아이디어가 나왔으며 1970년대 말에 광섬유 전송이 실용화 되었다. 그리고 1980년대에 광증폭기 기술이 등장하여 1990년대 후반에 광섬유선로 하나를 여러 신호가 공유하는 WDM(Wavelength Division Multiplexing) 기술이 마침 시작된 트래픽 폭발을 뒷받침하여 빠른 속도로 확산되었다. 이제는 거의 무한대로 여겨지던 광섬유의 대역폭도 아껴 써야 하는 시대가 다가오고 있다. 한편 기존 광전송망의 에너지 소모, 비용, 상면적 등의 확장을 최소화하면서도 계속 증가하는 트래픽을 수용하여야 한다. 본고에서는 최근에 표준화가 이루어져 시장이 열리고 있는 100G급 기술을 중심으로 광전송 기술의 최근 동향을 요약하였다.

In this paper the recent research and application activities on smart structure technologies for civil infra structures in Korea are briefly introduced. The developments of structural health monitoring systems and effective retrofit/maintenance methodologies for infra structures have become active in Korea since the middle of 1990's, as the number of the deteriorated infra structures, mostly built on the rapidly industrialized period of 1970's, has increased very rapidly. Discussions are made on smart sensors, non destructive technologies, monitoring and assessment methods and systems for civil infra structures.

Since the concept was first introduced in the 1970s, transit-oriented-development (TOD) has greatly expanded in East Asian cities such as Hong Kong. Rail stations are built together with clusters of residential-commercial towers and government services to form a new style of living - a "rail village." This paper examines the composition, scale, spatial form, organization and operation of several typical rail villages in Hong Kong. The cases range across those planned from the mid-1990s to 2015. Based on the analysis of the rail village composition, the paper derives a development ratio to indicate the density, effectiveness and efficiency of a rail village catchment area. The ratio provides a useful and direct figure for the comparison of different stations, cities and development modes.

The purpose of this paper is to discuss recent notions of communicative competence, especially as it is presented in Korean EFL education. Communicative competence has been modified and reinterpreted several times since the term was introduced by Hymes (1970). Paulston (1974) and Savignon (1983) focus on social interaction while Canale and Swain (1980) offer four categories of communicative competence: grammatical competence, discourse competence, sociolinguistic competence, and strategic competence. In addition, Tarone and Yule (1989) can be viewed as a systematic and comprehensive concept as well as a multi-dimensional mode (Bachman, 1990). Brown (2000) presents linguistic and functional aspects and Savignon's (1983) sociolinguistic competence has been transformed into sociocultural competence (Savignon, 2001). This study shows which aspects of Korean EFL education have been changed' and what needs to be accomplished for enhancing student's communicative competence.
