At the time of research, middle school students gave rise to lots of social problems. It might be remedied by the proper education and leisure in a way. It was the physical activity that they liked most to any other. But the lack of physical education and facility could not be adequate to their needs. So this research was carried out to employ the urban park in the physical education and leisure space. And the followings were the things which were connected with the solution. It was not what all kinds of park should be physical park but the park which had completed facilities or not could be used as it, because there was a physical park in the current urban park act. A self-governing body had to realize the lack of physical education space and facility so as to establish an ordinance. And the problems which could be occurred during school hours could be solved by grouping schools which lay adjacent to a park. So walking and shuttle bus could help it.

The purpose of this study is to suggest the criteria for the damaged mountainous landscape based on the shape, location and ratio of damaged landscape. For the study, the preference and landscape adjectives were analyzed on visual images and simulations. The variables for analysis were the amount of the damaged ratio(10%, 30%, 50%), the location of the damage (upper, middle, lower) and the various forms of the damage(spot, line, area). According to the results of this study, in accordance with the amount of damage, the visual preference recorded its lowest with the a rate of 50%. As for the location of the damage, the lower-ridge of the mountain showed the highest preference, and the upper-ridge was recorded as the lowest. The linear damage type showed the highest preference. On the other hand, the spotted damage type showed lowest. The results indicate that the visual preference increases when there is a lower ratio of damage, as the damage locates at the lower-ridge, and also when there is a presence of linear formation development. The group of linear formation-the lower ridge-10% showed the highest preference, and the group of linear formation-the mid ridge-50% was the lowest with the results of 3-way ANOVA. The group of linear formation-lower ridge-10% in particular had virtually no differences of visual preference when it was compared with the original scene. The damage with the spotted formation, on the mid-upper location and the high ratio of damage were analyzed as factors that give negative influence on the mountainous landscape. The main features of mountainous landscape were reduced into two factors, 'total estimation' and 'spatial scale' by the factor analysis with total variance of 65.96%.

X-ray grid is the most important means to reduce the scattered ray from patients, but alternative way is air gap technique that is another name of Groedel technique. This technique is mainly used in chest radiography. Authors performed an experimental study on the air gap technique for chest radiography and obtained the results as follows; 1. In using the high voltage air technique, scattered ray could be reduced effectively, while the percentage of scattered ray was slightly increased than conventional grid technique. 2. In film contrast, 30cm air gap technique was inferior to 12:1 grid technique and contrast improvement was increased when the object was thicker and higher voltage was used. 3. The patient exposure dose was reduced about $25{\sim}45%$ compared with conventional grid technique by air gap technique used.

허준,Huh, Joon 한국조경학회 2009 韓國造景學會誌 Vol.37 No.4

병산서원을 대상으로 강학공간이자 내부 공간의 핵심인 강당영역과 외부지향의 매개공간이며 유상공간인 만대루를 중심으로 경관구조를 살피고 그 구도적 경관특성을 원심적 외부경관과 구심적 내부경관적 성향으로 구분하여 경관 이미지와 선호 요인을 비교 분석한 본 연구의 주요 결과는 다음과 같다. 병산서원의 중심공간인 입교당은 표고 약 85m 지점에 입지하고 있으며 전면에 노출된 병산(屛山)의 같은 높이까지 약 365m 이격되어 있다. 경관 매개요소인 낙동강의 폭은 백사장을 포함하여 약 240m 정도를 보이며, 병산의 경사도는 평균 $50^{\circ}$가 넘어 상당히 위압적 앙시각(仰視角)으로 지각된다. 만대루 중심에서 보여지는 병산의 앙각은 $10.5^{\circ}$를 이루고 있으며, 좌측 병산 최고봉은 약 $16^{\circ}$ 정도의 각도로 조망되는 경관구조를 이루고 있다. 한편, 입교당을 중심으로 한 강당군으로의 내부지향적 조망경관에 대한 시각 이미지 평가에서는 깨끗한 1.98, 아름다운 2.16, 친근한 2.20, 질서있는 2.21, 정적인 2.81 등의 변인이 높은 평가를 받아 경관적으로 단아하며 아름다운 공간이미지를 구축하고 있다. 만대루를 투사하고 낙동강변을 건너 병산까지 펼쳐지는 외부지향경관에 대한 이미지에 있어서는 열린 1.70, 넓은 1.78, 아름다운 1.96, 조화된 1.81, 질서있는 1.86 등의 변인들이 매우 높은 평가를 받아 틀에 넣어 조직화됨으로써 오히려 자연과 합치된 아름다운 경관으로 평가되었다. 병산서원 내부지향 및 외부지향 공간의 시각적 이미지를 설명하는 인자는 특이성인자, 심미성인자, 개방성인자, 자연성인자 등 모두 4개의 인자군으로 공간이미지가 함축되어 분석되었고 전체 변량 중 이들 인자군의 설명력은 55.90%이다. 병산서원 전체경관에 대한 시각선호에 가장 영향을 높게 미치는 변인은 심미성인자 및 자연성인자로 밝혀져 전통적 공간의 조망계획시 특이성이나 개방성의 창출보다는 심미성을 바탕으로 한 적절한 경관 노출과 차폐를 통한 자연성 확보가 시각적 즐거움을 창출하는데 보다 긴요함을 발견하였다. This study analyzes the systematic visual images and factors in and outside of the main courtyard in Byungsan-seowon. The results are as follows; In terms of space distribution, Ip-kyo-dang is located at an elevation of 85m and the distance to Byung-san is 365m. Byung-san with the mean gradient over $50^{\circ}$ looked so stiff, and the east side of that cliff is higher than west. In terms of the angle of elevation relationship between Man-dae-ru and Byung-san draw 10.5 degree and it suits with human scale. The D/H ratio of 1:3 makes the given place very spacious but the linear stiff shape of Byung-san may cause the feeling of closeness. The results of the visual image analysis of the main yard facing Byung-san is very positive with a score of 1.70 in openness, 1.78 in wideness, 1.96 in beauty, 1.96 in harmony for the spacious arrangement which overall, makes the seowon beautiful with many open spaces. There are 4 main implicated factors analyzed which are uniqueness, aesthetic, openness and nature. Out of the total variables, these factors' descriptive ability is 55.90% and the remaining 44.10% is error and peculiarities variables. The factor which contributed most to Byungsan-seowon's main yard's visual preference was the 'aesthetic' with B-values of 0.661 and 0.455 in the nature category.

The purpose of this study is to investigate landscape image and define elements of difference in visual preference of bridges on the Han River. To do this end, video was used as a media for the evaluation of the landscape image of 16 bridges on the Han River using a Semantic Differential scale. Data is collected by 50 students from Woosuk University, majoring landscape architecture. Final analysis utilized a total of 704 samples of data. Data is analyzed through descriptive statistics, and spatial image is analyzed by factor analysis algorithm Principle component analysis using Varimax method is applied far extraction and factor rotation. T-test is used to find the difference between the bridge type of preference with the data of factor score. Logistic regression is used to select the factors that influences the visual preference among the image factors. The results of this study can be summarized as follows; The image of whole bridges on the Han River is somewhat orderly, sequential and open. The degree of visual preference of unique bridge type is higher than normal but there are some differences in visual preference within the same type of structure. This suggests that the surrounding landscape is one of the important factor for visual preference. Factors covering the image of bridge are found to be 'aesthetic', 'structure','spatial factor', and 'shape'. Total variance is obtained as 60.4%. The aesthetic variables are the most important factor for visual preference and the structural factor presents no significant difference in visual preference between more preferred and less preferred bridges. Since the collapse of Songsu Bridge, we thought the structural factor is very important but the results of this study suggest that it is more important to consider the aesthetic and spatial factors of the bridge to increase the visual preference when planning and designing bridges. Simulations with more detailed data about surroundings should be utilized practical design.
