This study covers museum rest areas among the methods that reduce museum fatigue. The subjects of the study were Seoul branch of the representative National Museum of Contemporary Art and National Museum of Korea. These museums were compared and analyzed with The National Art Center of Tokyo and Tokyo National Museum. The first research step was the analysis of museums' floor plan, and the second step was the tracing survey of visitors' movement. The result of this study was as follows. The National Art Center of Tokyo and Tokyo National Museum had the rest space within the visitors' route along with good viewing areas. National Museum of Korea had poor viewing area even though there was the rest space withing the visitors' route. Lastly, Seoul branch of National Museum of Contemporary Art had the rest space out of visitors' route along with poor viewing areas. This study is meaningful in that it provided guidelines for museum space plan with visitors' route considered, so that their museum fatigue can be relieved along with the guideline that can be applied to space elements of rest space.

Unnecessary transportation of resources are one of the major causes that adversely affect construction site work productivity. Therefore, layout related studies have been conducted with efforts to develop management technologies and techniques to minimize the resource transportation made at site-level. However, although the necessity for floor-level layout planning studies has been increasing as buildings have become larger and floors have become more complicated, studies to optimize the transportation of materials inside buildings are currently not being actively conducted. Therefore, in this study, a model was developed using genetic algorithms(GA) that will enable the optimization of the locations of finishing materials on the work-floor. With the established model, the arrangement of diverse materials on complicated floors can be planned and the optimized material layout planning derived from the model can minimize the total material transportation time spent by laborers during their working day. In addition, to calculate travel distances between work sites and materials realistically, the concept of actual travel distances was applied. To identify the applicability of the developed model and compare it with existing methodologies and analyze it, the model was applied to actual high-rise residential complexes.

Applying VR technology to animation areas is emerging as a trend of recent years. So if you use this VR technology in traditional ink animation, 2D art piece is expected to be equipped with a new narrative style and visual and auditory language, making it a new animation genre. There's a lot of technical difficulties in putting the existing 2D ink image on a 360 degree display. VR ink animation has been created that gives depth to VR space by using layer extraction method based on depth of distance and placing layers extracted on curved surface that is aligned with depth in 360-degree space in the image of ink painting, which is the background of traditional ink animation. In the text, we took an overview on problems generated in extracting layers of distant view, close-range view and middle distant view from the existing image of ink painting and made suggestions of an effective way to approach them.

The study on Buddhism architecture in early Joseon dynasty was inactive. The period of King Sejo is important for studying the trend of Buddhism architecture in early Joseon, that was transmitted from the end of Goryeo dynasty, but it was difficult to know its exact situation due to lack of related records. The records were all written by Kim Su-ohn, which are Wongaksabi' 'Sangwonsajungchanggi' 'Bongseonsagi 'Geonginsajungchanggi'. The main hall was mainly second floor and there were necessarily annexed buildings at the right and left of the main hall. So the plane figure of $\Box\Box\Box$ was shown. It was a main stream for main hall. This layout may be referred to search for the origin of the layout in courtyard based structure(中庭形) in the late Joseon dynasty. Most of temples had 3 gates. Some part of horizontal corridor was used as 2 gates and the outer gate, far from main hall, was without corridor. The gate leading to front yard of main hall was called front gate, the next middle gate and the outer gate was Oisamun(外沙門) or Samun(沙門). Im most of the temples, people could enter into the front yard through pavilion which had the function of bell tower. The pavilions were located between front gate and first corridor. It is thought that this layout of the place for making bean curd outside the temple area will contribute to different studies on temples making bean cure in the future. The records about temples's foundation studied above are a little different between temples, but have more similarities. There common denominators represent the architecture tendency of Buddhist temples in the related period. It is thought that such a tendency was also shown on architecture of other temples during the reign of King Sejo as well as Buddhist temples.

A hyperbolic numerical model with multi-directional waves has been used to investigate harbor tranquility in Pohang New Harbor. Comparing numerical results with field data measured at two stations in the harbor, it was found that use of input condition of multi-directional waves is superior to the use of uni-directional waves. Calculations with unidirectional wave input give errors of about 12% at St. P2 and 26% at St. P3, while calculations with multi-directional wave input give errors of 4 % at St. P2 and. 14% at St. P3. Using the input condition of multi-directional waves, we investigate the tranquility of Pohang New Harbor with two layouts : the condition in 1994 when the downtime at the 7th pier was often reported and the condition in 1996 when the 4th disposal site was constructed. The numerical results show that the problem of downtime at the 7th pier cannot be solved by the construction of the 4th disposal site.

In order to control waves in coastal zones effectively, multi-cylinder piles as the economical structures are suggested. A three dimensional hydraulic model experiment was performed to investigate the hydraulic characteristics of the structure. An experimental study was carried out research the effect of wave control and harbor tranquility through the wave height analysis for the existing concrete wave breaker and the structure with acrylic multi-cylinder piles type at the same location. In the results, the effective order of harbor tranquility is shown as the wave breaker > the staggered arrangement of multi-cylinder piles > the regular arrangement of multi-cylinder piles.

In this paper, we design and fabricate an ultra small dual crossed dipole antenna operating at 2.4 GHz frequency. In order to miniaturize the size of the antenna so that it can be applied to a mobile device, a cross dipole is disposed on the upper two layers and a reflection plane, a horizontal matching circuit and a ground plane are arranged on each layer. The circuit was connected by a vertical through-hole. The size of the fabricated antenna is $21.61mm{\times}16.88mm{\times}1.27mm$, the measured reflection coefficient is -31.5 dB, and the bandwidth below -10 dB is 112 MHz. In addition, since the gain of the antenna is -4 dBi, it has the omnidirectional radiation characteristic, so it can be applied to various fields as an antenna for mobile devices.

The purpose of this study is to classify the building layout and plan types according to the urban location, use and function of civil and to analyze the characteristics by the type classified. After constructing a framework (Mathia type, Nagaya type, Detached House type) for analyzing Modern Private Housing Architecture in Gunsan, the research was conducted on 30 representative buildings, and a plot plan, a floor plan and elevation were created. After analyzing the relationship between the lot of land and the urban street, we classified the type of arrangement into Mathia type and Nagaya type which directly enter the building from the road, and derived the Detached House type which indirectly enters from the road. When we look at the use of the derived arrangement types, most of the Mathia type are commercial and residential buildings, and some of them are specially designed for commercial buildings. The Nagaya type appears in the form of commercial and residential house or residential private house, and the Detached House type is classified as residential style. As a relation with the urban street, the Mathia type and the Nagaya type are generally located on the main urban street, whereas the Detached House type is located on the small urban street. As a result of analyzing, the floor plan was changed according to the plot plan. The plan of the Mathia and Nagaya type are arranged to enter directly from the street, with commercial space being mainly located on the street, and the residential space being composed on the back or the second floor. the plan of the Detached House is a type that enters indirectly into the interior through a separate space (Courtyard), and forms an organic space between the residential interior and the front and rear yard. The purpose of this study is to investigate the Characteristics of a plot plan and a floor plan of Modern Private Housing Architecture in Gunsan by means of analysis considering the urban street, Uses of buildings, Construction method and the yard through actual measurement.

The single photo method has a lot of applications in forestry, traffic accident managements, industry, criminal investigation, and in daily life. In this study a new single photo method was developed by classifying into the Space resection method and the 2 Dimensional Perspective Transformation method. Metric and nonmetric cameras were used to analyse the accuracy by means of single photo method, and the errors in coordinates and lengths were studied by changing the number and arrangement of control points to obtain the optimum condition for the single photo method. The influence of number and arrangement of control points on the accuracy was relatively small in case of the Metric WILD P31 and ASAHI PENTAX 6$\times$7 cameras, where as for errors it was a major factor in the Non-metric Nikon FM2. To overcome these defects, at least 6 control points should be used for the errors to be convergent and they should be distributed evenly over the surveying area. It was found that accuracy increased as the object to be photographed was placed in the perpendicular direction to the axis of camera.
