태산(泰山)은 해발 1,532m로 중국에서 제일 높은 산이 아님에도 불구하고 "오악독존(五嶽獨尊)"과 같은 높은 명성을 가지고 있다. 가이드북은 특정 이벤트나 시설 등에 대한 안내와 설명을 담은 책이나 소개서이다. 특히 관광지에 대해 상세하면서 정확한 정보를 다른 상업홍보 보다 시각적이면서도 다량으로 제공한다는 특성이 있다. 이에 태산에 관한 경관을 묘사한 가이드북을 연구 재료로 활용하여 경관유형 및 요소 분석과 경관요소의 커널 밀도(Kernel Density), 평균중심(Mean Center), 표준차 타원(Standard Deviational Ellipse) 분석을 통해 태산경관 특성을 파악하였다. 본 연구 결과를 요약하면, 첫째, 태산의 경관유형 특성은 자연경관이 가장 많이 나타났으며, 이는 시문과 빅 데이터 분석에 나타난 인간활동 위주의 태산경관 특성과 다르다. 둘째, 세부적인 경관유형별로 보면 경관요소의 비중에 따라 많이 나타난 것은 지형, 구조물, 건물, 식물, 의미, 사람, 이미지 순이라고 할 수 있다. 셋째, 시계열별 경관요소로 보면 ''봉선(封禅)"과 ''제사(祭祀)", ''전설"은 1950년대와 1980년대에 많이 나타났으며 1990년대 이후는 ''등반", ''멀리 바라보기"가 많이 나타났다. 넷째, 태산 경관요소의 공간분포는 전시대에 걸쳐 태산 대정 (岱顶)과 대묘 (岱廟)에 많이 분포되어 있다. 이는 향후 태산 풍경명승지의 중요 공간이 될 수 있다. 그리고 전체적으로 경관요소는 태산 풍경명승지 집중분포에서 태산과 태안 도시지역을 포함하는 분산분포의 형태로 나타났다. 이는 향후 태산 풍경명승지의 경관 보정과 가이드북 재제작을 할 때 필요한 시사점을 제시하고자 한다.

The focus of this study is the promotion of green area volumes and their naturalness, water circulation system, decline of entropy, creation of biological habitats and linkage of separated urban green space. Re-presentative urban biotope survey sites were categorized as urban biotope, semi-natural biotope, and natural forest. In the urban biotope, a residential biotope was constructed near the Han river and in mountain areas. The green-area ratio at the housing complex was about 25%. GVZ(Grunvolumenzahl) was 0.35m$^3$/m$^2$ at the 5∼10-story housing complex, and 1.53m$^3$/m$^2$ over the 11-story. As for the green-area structure of the housing complex, canopy layer, understory layer, and shrub layer were not differentiated and the green-area volume was not high enough. The green-area ratio of school areas as a public area biotope was 5∼20%. GVZ was 1.12m$^3$/m$^2$ at Myungduk High School, and 1.78m$^3$/m$^2$ at Jeonggok Elementary School. In order to convert the urban biotope into an ecological area, green areas around the buildings should be connected to urban buffer green areas, and multi-layer structures should be established with natural plant species. In the semi-natural biotope, neighbor parks were created park in the vicinity of the natural forests. GVZ was 0.28m$^3$/m$^2$, and plantation was established with single layer structure and was definitely insufficient for the area. The urban buffer green areas have been established in strip corridors with the width of 20∼123m. In those areas, GVZ was 0.16∼0.27m$^3$/m$^2$ and had a deficient canopy layer, understory layer, and shrub layer. Soil conditions were not favorable for tree growth. In the natural biotope, GVZ of the plantation was 1.03∼1.5m$^3$/m$^2$ but the high crown closure of this area reduces the chance of species change and succession. GVZ of natural forest was 2.53∼2.57m$^3$/m$^2$. It is desirable to plant diverse plants and the natural forest should be succeeded by broad-leaf deciduous tree species. To improve the value of biotope at Kangseo-Gu, building height needs to be limited to reduce the environmental deterioration in the city. In order to maintain the water circulation system, water-permeable material is recommened when the urban surface areas are paved. The establishment of a water circulation system will improve ground water levels, soil moisture, water quality, and habitats. In order to improve biological diversity, it is desirable to have multi-layer structures in urban green areas with native species.

This paper is focused on Damheonseo(湛軒書), an anthology written by Hong Daeyong, and I deal with Chinese Architectural views which he had experienced in his itinerary to Beijing, and the vivid pictures of Joseonkwan (called the Koryo or Joseon Embassy) located in Beijing at that time. He was a scholar of great erudition over astronomy, mathematics, military science, politics, and so on. He was interested in practical sciences at early time, and criticized secular scholars full of vanity who had presented purposeless articles. In his age of 35, Qianlong(乾隆) 30 (1764, Youngjo 41), he, a military escort, accompanied by Hong Uk, Joseon envoy and his uncle. Before his itinerary, he self-studied Chinese. Also, during a long journey he got new experiences and information around each area, deviating his group whenever he had some times. He could get more variant experiences than others because of his character full of curiosity, and his observations from the vivid lives of the time helped us get various views between Chinese and Korean architecture. Likewise, although he denounced Qing(淸) scathingly as a barbarian, he mentioned several points about the characteristics of Chinese architecture at that time. First of all, totally Chinese architecture had strong rational and practical points. Secondly, based on bountiful products, buildings along streets shown in Chinese city had sophisticated compositions, and luxurious and magnificent appearances. Thirdly, using the brick from walls to houses was so universal. Fourthly, the layouts of building with three- or four-closed courtyard had very orderly shapes, and the structure of street was also so arranged. Finally, because of stand-up lives, the scales and appearances of interior space were even more extended, and storages were less developed than those of Joseon. As another points, I found that Joseonkwan was moved next to Shushangguan(庶常館)from Huidongnanguan(會同南館) around Hanlimyuan(翰林院), and had been remodeled into a house with Korean custom in using the inner spaces, although it was followed by a closed courtyard style. Likewise, I recognized that Ondols were sure to be established in all temporary houses during the journey to Qing, and felt their strong traditional residential custom in such mentions. Now that the past pictures have disappeared and ways of life and our values have been largely changed, this study has very important meaning in comparing the ancient Chinese and Korean architecture.

Objective: The purpose of the this study was to test the effect of the alcohol preventive educational program for elementary school students through developing the web-based learning instruments. It will prevent the serious alcohol problem for adolescents and be the opening-learning according to learner's needs beyond the traditional classroom learning which has limitation of space and time. Method: This research designed based on web-based instructional system design by In-sung Jong(1997). This study was performed on the elementary school students who are the six grade in M city. The number of experimental group was 72 and control group's number was 72, totaled 144. Data were collected from September, 30th, 2004 to November, 5th, 2004, totaled 37days. The pretest and the posttest for web-based alcohol preventive education program were tested about knowledge and attitudes toward drinking. After the performance, the posttest was also tested the effect of this program under items by the interest of web-based learning, satisfaction, adequateness of material and so on. The data analysis was done using SPSS/Win 11.0 program. Result: The results of this study are as follows: 1) Compared with control group, experimental group which was educated the web-based alcohol preventive educational program for elementary school students was improved the knowledge on drinking, thin there was no significant difference. However, it showed significant difference between two groups after education. It was, therefore, partially supported. 2) Compared with control group, the experimental group which was educated the web-based alcohol preventive educational program for elementary school students showed significant difference in attitudes toward drinking. After education, it showed no significant difference attitudes. toward drinking between experimental group and control group. It was, therefore, partially supported. 3) The degree of learning motivation was an average.595 of 1 after learning applied to by the web-based alcohol preventive educational program for elementary school students. Then, it is relatively more higher than the result of existing studies. So, it showed that the motivation was done well. 4) Correlation among study variables It showed that there was the significantly positive correlation between knowledge and attitudes toward drinking of pretest experimental group. Also, there was the significantly positive correlation between attitudes toward drinking and learning motivation of pretest and posttest experimental group. Conclusion: I found that the web-based educational program helps the elarning process for the health education in the school field which the instructional materials lack. As a result, the web-based education motivates the learner's pleasure and promotes the learners interest. Also, it is possible for students to learn according to their own learning pace, repeated learning and active learning participation in the necessary parts. Therefore, I think the web-based educational program is worth as a intervention to get positive influence for the health education.

This study aims to identify and analyze the factors that influenced the construction of London Eye which was led by private groups, including characteristics in progress, differentiated value in design, the combination of technology and design, and construction costs. The results of this study were the followings. 1) London Eye provides a new construction method for a landmark in the downtown in that the architects became the clients of the project which might have been hoarded, procuring the construction costs and completing it by themselves. 2) London Eye presents a space utilization method where undeveloped spaces in the downtown are used in three-dimensions by erecting a structure on the river with a minimum land. 3) The process of design, production and erection is propelled the realization of technical intention design with one system and from at the initial stage, the participation of the engineer where the designer is equal with you must accompany. 4) London Eye is endowed with strong shape by a circle in design concept, which is the simplest geometrical figure, and it provides organic relationship between the past and the present by utilizing historical elements in various ways. 5) The construction was completed through four phases including idea phase, promotion phase, turn-key contract phase, and design-build phase. The most critical factor to the success is derived from the direct contact with Involved companies from the production phase. 6) In a project facing many challenges in terms of technology, the design-build method proves to be a more effective method than turn-key contract in that it may more allocate risks and enable coherent implementation of the core concept in design. The organization for the design-build method was composed of three phases including general affairs, responsible contracting by sector, and cooperative system by sector. Since that was a new concept structure, high-level contractors who hadn't had existing cooperative relationships with one another formed new cooperative relationship, while collaborating companies who had long cooperated led the responsible contracting and sub-cooperative system, which resulted in reduction of risks and time. 7) The major factors to change design were the design characteristics, derived from a technically great combination, and the opening time. 8) A new erection method was applied to London Eye, a structure that overcame the limitation in land and period, and the process of installation demonstrated that it is an important value for the construction of a landmark in the city. 9) In spite of many visitors and tremendous operational income, the factors that London Eye fails to free itself from debts include the construction costs expended double than expected, and interest burden to the investments, which occurred in the course of procuring the costs. Absolute limit in time increased the construction costs, resulting in being a great obstacle in the course of operation.

Human beings have pursued development and economic betterment; thus, enhancing convenience and prosperity. A flourish of human civilization upon the industrialization results a massive urbanization. However, human beings have connived the environmental importance in the course of rapid urbanization. The environmental quality now becomes one of the most important factors that determine the quality of life in a city. Many studies were proceeded about the heat island effect in large cities. In general, most studies have been done to investigate urban microclimate phenomena using meteorological network or AWS (automatic weather station) data. Those preceding studies do not seem to sufficiently reflect the and thus, failed to show regional representative. In this study, temporal Landsat TM satellite imageries of May 20, 1987 and May 21, 1999 were 뻐d in order to detect the surface temperature of the study area using the band 6 ($10.4{\mu}m{\sim}12.5{\mu}m$). The surface temperature distribution detected by the band 6 of Landsat TM was over layed with the land cover classification data in order to investigate the temperature difference of the paved road and the riparian areas of the stream. As a result, a surface temperature difference as much as $3^{\circ}C$ between the paved road and the riparian areas with vegetation was observed. This study concludes that the land cover change is one of the main causes of urban heat island effect which may be closely affected by the paved areas and roads. Besides, the change of the atmospheric temperature followed by the urban secular change could have been confirmed. In the case of Yangjaecheon stream which underwent a heavy environmental restoration in 1995, the temperature was decreased as much as $0.6^{\circ}C$ after the restoration. The results of this study is expected to contribute to develop an urban space in harmony with the healthy human life and the environment respecting the crucial role of vegetation to stabilize the urban environmental dynamics.
