  • According to flow of energy, the loss occurs through walls, roofs, windows and so on. Among these case, most of the loss that is about 45% occurs through windows. windows's U-value is six times higher than wall's one according to Building code, so the loss through windows accounts for very much rates. Currently, Exterior wall's U-value about building envelope is 0.35~0.58W/ mK, but windows's one is 3.3W/ mK. It means that the loss through windows occupy very much amounts relatively. Therefore, the solution is required to reduce energy loss and increasing displeasure caused by excessive influx of solar energy through windows, to solve the problems Like decoloration on indoor furniture an clothes by harmful ultraviolet rays, air conditioning and increased cost. Therefore, on this paper, Thermal Performance was evaluated through actual test about high insulation Super Window which can improve thermal performance and the Simulation result was compared with actual resul by using Simulation program WINDOW and THERM.

  • Many university campus facilities are recently remodeled to provide the substantial learning rights of handicapped students to embody the dignity and value as man by many campus authorities. This study aims to identify the interior public spaces between entrances and class rooms for handicapped students of S and D campuses. The summaries of this research are as follows. $\bullet$Since S campus was built long years ago before the related law for the handicapped person enacted, it was thought that the campus master plan to consider handicapped students' activations must be established and the campus educational facilities was remodelled by campus master plan. $\bullet$Since D campus was built lately after the related law for them enacted, it was thought that the officer who is responsible for campus facilities for handicapped students put in order it by repair plan every year. By remodelling every year steadily according to each campus master plan, all handicapped students must be guaranteed the same learning rights as normal men to remove obstacles as the upper mentioned imperfections in using exterior campus facilities.

  • The use of drones and laser scanners have the potential to drastically reduce the time and costs of conventional techniques employed for field survey of cultural heritage buildings. Moreover, point cloud data can be utilized to create an as-built Building Information Model (BIM), providing a repository for consistent operations information. However, BIM creation is not a requisite for heritage buildings, and their technological possibilities and barriers have not been documented. This research explored the processes required to convert a heritage university building to a BIM model, using existing off-the-shelf software applications. Point cloud data was gathered from drones for the exterior, while a laser scanner was employed for the interior of the building. The point clouds were preprocessed and used as references for the geometry of the building elements, including walls, slabs, windows, doors, and staircases. The BIM model was subsequently created for the individual elements using existing and custom libraries. The model was used to extract 2D CAD drawings that met the requirements of Korea's heritage preservation specifications. The experiment showed that technical improvements were needed to overcome issues of occlusion, modeling errors due to modeler's subjective judgements and point cloud data cleaning and filtering techniques.

  • The transition from manufacturing to service-based economies in highly developed societies during the post-industrial period resulted in the decline of the industrial landscape, leaving it abandoned or underutilized. In pursuit of revitalizing the obsolete industrial space, innovative design techniques based on adaptive reuse are applied to retrofit modern functions to create a new cultural space and preserve the historical, symbolic, and cultural importance of the abandoned industrial facilities. Design considerations based on facade redesign have proven to be one of the most adopted techniques that can help in recreating a new function for the vacant industrial buildings and integrating them into the present-day urban fabric. This paper examines the facade renovation elements used for the adaptive reuse of 15 abandoned industrial buildings presently used as multi-purpose facilities in South Korea. Through a questionnaire survey, this study analyzes the respondents' preference for different facade renovation elements in the 15 sites according to age and gender. The study found that both genders showed similar preference patterns between most elements. But on some elements, females were keener and expressed a stronger opinion than males. There were much more females than males who perceived color and material as the most important exterior elements. The findings of this study can be used for the adaptive reuse of industrial buildings according to user preferences for different facade renovation elements.

  • The purpose of this study was to examine needs of residents on the storage according to unit size in apartment. In order to achieve our goal, the questionnaire survey was used. We sampled the questionnaire surveys of 250 households in Seoul whose apartment sizes had been more than 20 pyung. The data collected by the questionnaire survey was analyzed by examining the frequency, percentage on the SPSS/PC+. The results of the study were obtained as follows: 1) In research on the actual storage condition, Residents tended to feel constraint on the storage of the season goods and the storage satisfaction on the service area was found lowest. Therefore, there needed to design the balcony more efficiently for the storage and the interior storage for the season goods. 2) In research on consciousness and attitude about the storage, residents tended to keep the goods of no use and prefered to arrange neatly rather than use conveniently. Therefore, there needed more efficient space in the balcony for the storage of the goods of no use and the closed furniture rather than the open furniture was suited for arrangement. 3) In research on the storage needs, needs for the built-in furniture in all apartment sizes showed highly and residents wanted a space for the exclusive use of the storage. In a solution, it was proposed to equip with the interior storage and the exterior cooperative storage. In the conclusion, needs of residents on the storage according to apartment size were different little. The small size apartment had the serious storage problems and wanted the efficient space plan for storage.

  • Purpose: This study was aimed at providing the basic checklist as a means to assess the crime risk in physical environment of the pedestrian passage at residential area. Method: For this purpose, the preliminary checklists were selected according to the review of the precedent studies of checklists in exterior pedestrian passage. The usefulness and the importance of the preliminary checklists were analyzed through the seven expert group meetings, the 87 questionnaires survey of the crime experts & the architectural/urban experts, preliminary assessment and field survey. Results: The assessment categories of checklists were sorted into six types, i.e. spatial structure & function, lighting, landscaping, security facilities, other facilities and cleaning & maintenance. The 49 checklists were proposed according to the assessment categories. The final checklists were divided key checklists and general checklists based on the results of experts' weighting of each list item. There were significant differences between crime experts' weighting and architectural/urban experts' weighting in several checklists, i.e. dividing between pavements and streets, the brightness of light, white light.

  • This study is based on the results of the $7^{th}$ Korea Human Size Survey (Size Korea). The standard body shapes of Korean women between 25 and 34 years old were analyzed and used to develop a prototype princess line for wedding dresses. or this purpose I conducted a literature review and a survey of the actual situation of domestic ligaments. In order to select suitable ligaments for the standard body type of 25~34 year-old Korean women, I collected the most representative ligaments from around the world: Stock man from France, Superior from the USA, KIIYA from Japan, and Pig and Nonno from Korea. They were then compared and analyzed. In the form of a formal wedding dress, a prototype princess line was developed by a draping technique in order to finely implement the human body fitting. To develop the prototype of the princess line, I made test garments with muslin. 25 to 34 years old Korean female standard body type Three human subjects close to the average measurement value were selected as subjects. An exterior appearance evaluation questionnaire was created with 28 questions focusing on the main parts of the prototype princess line. The clothes were evaluated three times. In this study, aesthetic and functional elements were considered for the development of princess line prototypes for wedding dresses. In addition, the amount of spare area was given differently. This study is significant in the achievement of a dress line closest that closely matches the human body line of the standard Korean female body type.

  • The success of 2002 Korea Japan Worldcup became a good opportunity to give the message of revival to the people of Korea. With the effect of it, the national brand image has risen. Nevertheless, in order to maximize the chance of time, the most necessary thing that need to be done is to find the strategic counterproposal of the Post Worldcup. Especially, to find the more active plan in the respect of economy. In this research, we have studied the IT industry(especially SI industry) of the economy in order to look into the strategic counterproposal to get the development effect after the Worldcup. We mainly analyzed the SI industry in the respect of economy, because it is not only a high-value added industry of the integration of knowledge and technology but also a high-tech industry which has a spreading effect on the related industries. To implement the analysis of SI industry, derive and verify the strategy, and get the activating plan, we studied with 4 stages. Firstly, analyze the exterior environment and the interior strength with the Competitive Strategy Model(Specially, 7 Force Model & Value Chain Model). Secondly, get the strategy with SWOT analysis. Thirdly, verify the Strategy with interview and survey. Fourthly, classify the SI industry activation plan into 5 kinds after Worldcup through panel discussion and seminar with the data which we got through interview and survey.

  • In the present study, we assessed the accuracy of aerial triangulation using a UAV (Unmanned Aerial Vehicle) capable of network RTK (Real-Time Kinematic) survey in a disaster situation that may occur in a semi-urban area mixed with buildings. For a reliable survey of check points, they were installed on the roofs of buildings, and static GNSS (Global Navigation Satellite System) survey was conducted for more than four hours. For objective accuracy assessment, coded aerial targets were installed on the check points to be automatically recognized by software. At the instance of image acquisition, the 3D coordinates of the UAV camera were measured using VRS (Virtual Reference Station) method, as a kind of network RTK survey, and the 3-axial angles were achieved using IMU (Inertial Measurement Unit) and gimbal rotation measurement. As a result of estimation and update of the interior and exterior orientation parameters using Agisoft Metashape, the 3D RMSE (Root Mean Square Error) of aerial triangulation ranged from 0.153 m to 0.102 m according to the combination of the image overlap and the angle of the image acquisition. To get higher aerial triangulation accuracy, it was proved to be effective to incorporate oblique images, though it is common to increase the overlap of vertical images. Therefore, to conduct a UAV mapping in an urgent disaster site, it is necessary to acquire oblique images together rather than improving image overlap.

  • In photogrammetry, GCPs (Ground Control Points) have traditionally been used to determine EOPs (Exterior Orientation Parameters) and to produce DEM (Digital Elevation Model). The existing DEM can be used as GCPs, where the observer’s approach is a difficult area, because it is very restrictive to survey in the field. For this, DEM matching should be performed. This study proposed the fusion method using ICP (Iterative Closest Point) and RT (proposed method by Rosenholm and Torlegard, 1988) in order to improve accuracy of the DEM matching. The proposed method was compared to the ICP method to evaluate its usefulness. Pseudo reference DEM with resolution 10m, and modified DEM (random-numbers are added from 0 to 2 at height; scale is 0.9; translation is 100 meters in 3-D axes; rotation is from 10° to 50° from the reference DEM) were used in the experiment. The results proposed accuracy was highest in the matching and absolute orientation. In the case of ICP, according to rotation of the modified DEM being increased, absolute orientation error is increased, while the proposed method generally showed consistent results without increasing the error. The proposed method would be applied to matching when the DEM is modified up to 30° rotation, compared to the reference DEM, based on the results of experiments. In addition when we use Drone, this method can be utilized to identify EOPs or detect 3-D surface deformation from the existing DEM of the inaccessible area.
