When the past architecture is renovated, the important point is to approach from social and historical point of view. In Europe, there are many cultural and architectural hereditaments by backed-up ancient history and are usually happened modernistic applications of these architectures. Specially, when the past architecture is renovated, this study is focused on cases of museum and gallery which the people are approachable by me. I studied how to expressed the durability and to distinguish the design characteristics that is connected with the past from the European cases at modernistic point of time. The design characteristics are discovered two kinds. The first is 'consideration of the past architecture' and the second is 'consideration of the present age'. The results of this study are as follows； 1. The component reanalysis 2. The use of material 3. The introduction of symbolic elements 4. The Change of function

This paper presents the appplication of computer vision for the purpose of determing the position of the unknown point in the plane. The presented contrik method is estimate the six view parameters reqresenting the relationship between the image plane coordinates and the real physical coordinates. The estimation of six parameters is indispensable for transforming the 2-dimensional camera coordinates to the 3-dimensional spatial coordinates. Then, the position of unknown point is estimated based on the estimated parameters depending on the cameras. The suitability of this control scheme is demonstrated experimentally by determining of position the unknown point in the plane.

Hand posture recognition has played a very important role in Human Computer Interaction (HCI) and Computer Vision (CV) for many years. The challenge arises mainly due to self-occlusions caused by the limited view of the camera. In this paper, a robust hand posture recognition approach based on 3D point cloud from two RGB-D sensors (Kinect) is proposed to make maximum use of 3D information from depth map. Through noise reduction and registering two point sets obtained satisfactory from two views as we designed, a multi-viewed hand posture point cloud with most 3D information can be acquired. Moreover, we utilize the accurate reconstruction and classify each point cloud by directly matching the normalized point set with the templates of different classes from dataset, which can reduce the training time and calculation. Experimental results based on posture dataset captured by Kinect sensors (from digit 1 to 10) demonstrate the effectiveness of the proposed method.

The purpose of this study was to analyze the characteristic of each view in an apartment unit in terms of the quality. This study was accomplished by two research methods; the field survey on 181 apartment complexes in Daegu, and the preference evaluation on 24 cases sampled in the sense of its location, i.e. inside or outside of a complex. In the field survey, view targets were categorized into various items such as a building, a road, a mountain, a tree, another apartment, the sky, and so on, and the characteristics of the distance from a viewer to view targets and view of the level in an apartment were analyzed. In the preference evaluation, 24 cases, each one has one of the follows; the natural view, the artificial view, and the combined view of the both, were chosen and those were evaluated by 167 interviewees. As a result, the conclusions from the study were drawn as follows; 1) The view, the combination of buildings, roads, mountains, trees, apartments, and the sky, is usually seen in an apartment unit. 2) The type of view target is more significant to a person than its location. 3) The natural and combined view are preferred to the artificial one. 4) In the case of the same outside view, a person likes the open view more than the somewhat covered one.

'What is nursing' this question could always be arised and such a question could bring forth the new possibility to definete the nursing concept more clearly. At the middle of 19th Centry, Mrs. Nightingale defined the concept of nursing as follows; 'Nursing is a kind of treatment act to aid the patient so that the health of patients may be recovered naturally, as keeping the most comfortable circumstances.' But after then, the role and function of nurses about purpose and method of nursing has continuously been studied, as the social circumstance has been changed. The fact that care provider and client have the same concept about nursing is very important at the first step of assessment. But at the present time, the care provider and client have not same concept yet, so the difference of unrsing concept between care provider and client is analyzed in this study. This study would be belived to be helpful for the advance of nursing in the future. In this study, 20 questionare from nursing objectives developed by Abdellah(basic care needs, sustenal care needs, remedial care needs and restorative care needs) are used for adult. The data of this study by the 6 point rating scale are analyzed by SAS as follows; 1. Respondent's view is that nursing is necessary in case of group(school or company) rather than private and in case of abnormal conditions rather than normal conditions. 2. Every questionares of nursing objectives are divided into 4 points of view such as basic care needs, sustenal care needs, remedial care needs and restorative care needs are examined. The evaluation by 6 point rating scale revealed that $5.08\pm0.65$ point in basic care needs $4.93\pm0.68$ point in sustenal care needs $4.91\pm0.80$ point in remedial care needs and $4.61\pm0.91$ point in restorative care needs. While basic care needs and substenal care needs that need more physical care show high points, remedial care needs and restorative care needs that need more psychological, social and spiritual care show low points. 3. It was checked whether there is any significant difference between above 4 point of views in nursing objectives and qeneral characteristics or not. As a result, there is significant difference between 4 point of view and ages, educational level, marriage, composition of children. And also there is significant difference between religion and basic care needs, remedial care needs and restorative care needs. But there is no significant difference between any point of view and sex, occupation, experience of admission and experience of family admission. As this study is based on the data gethered from a restricted area, the result can not represent the opinion of all the clients. Therefore the same kind of study should be carried out on many areas repeatedly and also it should be tried to extract objective concept. And also periodical study is needed to observe the changing process of nursing concept.

Utilization of CCTV in crime prevention for public safety is accepted as the most effective measure in terms of crime prevention and control. Also, it is frequently used as a device that shows evidence of an unexpected situation or record on public social relationship. However, it is rare to find a study that qualitatively accessed the monitoring performance of a certain space depending on the choice and positioning of CCTVs. Thus, this study suggested a technology that can quantitatively compare and assess the monitoring performance of CCTVs depending on view angle and effective sight range of cameras as well as the monitoring performance depending on positioning measures. For the analysis, the concept of 3-dimensional surveillance field in the form of a frustum was suggested while deriving 3-dimensional range of sight and quantitative monitoring performance by applying Isovist theory. For the analysis technology, space of analysis subject, point of view (camera), and target point (measurement node) were installed at a 3-dimensional space and in use of ray-tracing algorithm, the line segment that was visually connected between the point of view and target point was extracted and accumulated. For such verification, analysis application was constructed and then applied to four alternative models on view angle and distance as well as four alternatives on positioning in order to verify its efficacy. Through the experiment, it was possible to compare and assess visibility depending on alternatives while quantifying the results by understanding the shadow areas beyond the monitoring range.

The object of study is to verify the accuracy of internet survey by comparing database data and internet survey. Internet survey was conducted on August, 2012. Respondents were subscribers of KISTI NDSL. Variables were age, organization as demographic variables, number of use, and period of use as attitude variables. Mismatch rates of age, organization, number of use, and period, are 7.5%, 5%, 92%, and 55% respectively. We could estimate the mismatch rate for age as 3% as a pessimistic point of view, and 1% as an optimistic point of view by detail verification. The mismatch rates of organization are 4.5% as a pessimistic point of view, and 2% as an optimistic point of view. The mismatch rates for the frequency of use, the period of use are very high, because measurement error, problems in memory, and internet attitude, etc. Implication of this study is that data of internet survey could be reliable. Many further researches are needed for verification of internet survey.

The aim of this study is to investigate the method to enhance user cognition for "STM information(Short-term Memorable Information)" that is relatively accessible to information in a short period of time in information design types. What stands out from this study is the design attributes and expression method of information in a broad perspective. By 4 visualization attributes of function variable; 'Operations', 'Events', 'Methods' and 'Use cases', STM information should be satisfied by the attribute of 'Understandable' and 'Accessibility' from the point of view of visual representation and by the attribute of 'Errorless' and 'Timeliness' from the point of view of user operation. As the expression method of each perspectives, I suggested "Attribution theory", "Cognitive model", "Maximization of Proactivity", "Minimization of surplus information" and "Using dual-code" in the point of view of visual representation, and "Context effect", "Using memory code" and "Two methods of information scanning" in the point of view of user operation. I assured that above-mentioned methods are efficient and cognitive pattern of user for STM information is found out by survey and interview.
