The arc thermal metal spraying method (ATMSM) has been used in Korea to improve the electromagnetic pulse (EMP) shielding effect of building and infrastructure by three machines of MS, KMS and HMS (Metal Spray, Korea Metal Spray, High-frequency Meta Spray). The adhesion ability of sprayed metal was found to be 58.32, 64.66 and 87.62% for MS, KMS and HMS, respectively. The metal sprayed area per hour of MS, KMS and HMS was calculated and found to be 14.3, 19.25 and 22.16㎡/h, respectively. The HMS showed the highest metal spray area attributed to the diameter of metal wire i.e. 1.6mm which sprayed 80 mm with 18 m/min. There was minimum loss of metal and the highest efficiency by HMS compared to others. Therefore, it is suggested to use HMS for metal spraying by ATMSM to enhance the EMP shielding effect.

Planning for the space of the Media Medical Department requires the details about the efficiency of the equipment and the operation in professional sector. For that, as designing, it is necessary to keep communicating with the experts on the technology and the officials from the company producing the equipment. One of the common concerns is not only how to insure enough room for the future extension and the upgrade of the equipment, as concerning the scale of the hospital, but the plan to cover movie cameras. As technology has been developed, despite the fact that machinery tend to be small, it can be possible to require continuously about the concerns of the scale because the camera taking body-picture tend to be much bigger and more complicated than before. Currently used diagnostic media techniques are divided by the method and the feature of the equipment such as Diagnostic X-ray, Ultrasound, CT, MRI, Angiography. The general and special photographing units which are used more than the other diagnostic parts, must be planned not for experiencing any inconvenience and unnecessary risks for the patients and must accept technical requirements. Also, it must be designed not to be seen as a clinic zone, as concerning the psychological stability of the patients. However, study of the general and special photographing units among the domestic general hospitals is insufficient. Also, as there is shortage of the material considering the development of the equipment, when planning, it's involving a lot of difficulties. Thus, this study has got a purpose on giving the basic material which is essential for further study, as suggesting the planning guidelines and the alternative plans for the general and special photographing units in a general hospital.

Recently a number of media facade buildings making beautiful cityscape landmark has been increased in Seoul. However, indiscreet adaptation of media facade cause problems such as light pollution and poor city image. This paper was to investigate luminous characteristics of media facade building. Five representative media facade buildings in Seoul have been selected. The CS-100 and ProMetric-1400 were used to measure the luminance and color temperature of the facades. The measurement points were located at the opposite spot of the building. The results showed that maximum media facade luminance of such buildings exceed Seoul design guideline. Also, color temperature with over 5,500[K] that exceed the design guideline were mostly used in all the facades.

Estimated construction cost is an important index to secure an optimal budget which needs to go into construction projects in the previous of basic design phase. In order for public institutions to calculate the estimated construction cost, the cost per unit area of public buildings is used. However, the current calculation method of the estimated construction cost in public buildings is impossible to reflect the characteristics of many facilities and combinations. The purpose of this study is to develop an estimation model in the previous of basic design phase for the elementary, middle and high school facilities. it is expected that it is possible to estimate the construction cost of the elementary, middle and high schools in a reasonable and reliable manner through the estimation model developed in this study.

Settlement at reclamation area caused by secondary compression should be considered using spatial evaluating method because the thickness of consolidation layer varies at every location. Probabilistic method can be implemented to evaluate uncertainty of spatial distribution of secondary compression. This study spatially evaluated mean and standard deviation of secondary compression in the overall analyzing region using spatial distribution of consolidation thickness estimated by ordinary kriging method and statistical values of soil properties. And then, the area where secondary compression exceeds a design criterion at the specific time was evaluated using probabilistic method. It was observed that the area exceeding the design criterion increased as the variability of $C_{\alpha}/(1+e_o)$ increased or the probabilistic design criterion 0: decreased. It is considered that the probabilistic method can be used for the geotechnical design of soft ground when a probabilistic design criterion is established in the specification.

Purpose: In Korea, the increase rate of the number of mentally ill patients increases, and the hospitalization period for severely mentally ill patients to stay in acute wards is long and the re-hospitalization rate is high. In order to improve the dignity of patients with acute mental illness and to plan a therapeutic environment for this, this study attempted to present a basic framework of spacial planning for establishing guidelines for psychiatric acute ward in general hospitals. Methods: By analyzing the acute psychiatric ward guidelines of the UK, Australia, and the US., this study analyzed the areas and required rooms of psychiatric acute ward in general hospitals, as well as the net floor area of each room, and the connection between the rooms. Results: As a result of the study, the basic framework for the ward areas and the required rooms, the net floor areas of the rooms, and the connection between the rooms were presented for the establishment of guidelines for the psychiatric acute ward in general hospitals. Implication: The results of the study will be used as a basic framework of space planning for establishing of guidelines for the psychiatric acute ward in general hospitals and will contribute to the establishment of detailed guidelines based on the space configuration through surveys and analysis of space use status, operation status, and expert interviews in Korea.

The purpose of this research is to evaluate an accurate biotope area ratio model with efficiency and convenience of database management through promoting sustainable development to provide people amenities in a new town. In particular, the biotope area ratio is used not only in the environment impact assessment but Green building certification criteria. But now there is no any index map of biotope. So it is very hard to implement with data for supplement results. In this research, we suggest the model of integrated attributable information. The evaluation of biotope area ratio is to include a basic land use planning map and a building coverage area which is a wall of greening surface and roof. In case of non building coverage area, the evaluation of biotope area ratio is to include water space, artificial ground, natural ground and pervious gap-pave. A weighted value on the spatial information is combined into the information. And then the merged one is given a land use planning information in a block. In the weighted value on the space type information, it is possible to in its circumstances. Therefore, it can be substituted a correspondence of numerical change for various values elastically in this model.

The Purpose of this study is to improve construction quality with area calculation methods from BIM design technology. BIM has been supporting public-private-organizations and academic circles as a solution technology to manage and produce informations effectively from construction field including facility manage one. BIM standards are necessary but not sufficient for achieving perfect practical application in South Korea. In particular, development of architectural rule based area calculation methods is very urgent and important to improve construction quality. To solve those problems, methods and standards on area calculation are developed and its effectiveness of the proposed BIM-based methods is defined through the analysis between the existed area calculation method and process which are 2D based. This study will not only improve economic efficiency and accuracy of the construction quality but also settle the BIM environment in the domestic architecture.

Purpose: Most contemporary office buildings supply external views, a sense of openness and a sense of time to their occupants by adopting the curtain walls, which are equipped with an outer cover having large window area. As a result, the amount of radiation increases, adversely affecting cooling load during the summer in office buildings. Although solar radiation decreases heating load and reduces energy costs during the winter period, due to the characteristics of offices where occupants work largely during daytime, the cooling load is important compared to the heating. Therefore, diverse measures to resolve those trade-offs and annual energy cost have been investigated. Method: In this study, the annual thermal load was comparatively analyzed according to the slat angle of the venetian blind along with lighting control technique. Result: After selecting effective conditions, in order to resolve such issues, this study established automated control strategies of slat angle depending on the window-to-wall ratio and zone orientation, so that the findings of this study can be effectively generalized to other circumstances.

Due to the increasing concerns about the buildings which have affected the global environment, most countries have enacted a regulation for the sustainability of domestic buildings. In 2008, the Korean government started to enact a regulation of apartment and office buildings for energy saving. Many research on the sustainable apartment building focuses on $84m^2$ or larger type in response to market demand; therefore, small size type such as $46m^2$ type needs to be researched. In addition, the research on the orientation and window to wall ratio of the building have been separately studied as a means of energy reduction; therefore, the research on correlation of the orientation and window to wall ratio hasn't been fully explored yet. This paper analyzes the energy demand of the apartment building as the change of orientation and window to wall ratio among $46m^2$ and $84m^2$ type. In conclusion, when reducing the window to wall ratio, energy demand was reduced, except when the orientation of the building was between from +10 to -20 from the south.
