This study examines history of Korean peony patterns and characteristics of peony patterns on the fabric. It is classified according to expression methods, and it analyzes the characteristics of 71 kinds of peony woven on 66 Korean fabrics. First, it was observed that 38 of the 66 studied fabrics (57.6%) were relics from the 17th century, and from this it can be deduced that the peony patterns began to appear regularly around the latter half of the 16th century and were used habitually in the 17th century. Second, 71 kinds on 66 fabrics can be divided into Real Type, Design Type, and Abstraction Type according to expression methods. Among these types, 49 kinds of them are Real Types (69.0%), forming the greatest part and 19 kinds belonging to the Design Type (26.8%), and lastly, 3 kinds were under the Abstraction Type (4.2%). In particular, peony patterns of Design Types and Abstraction Types from the 17th century and from the 19th century to the 20th century were more prevalent, compared with those before the 16th century or the 18th century. Third, Real Types shown on the Korean fabrics are subdivided into 9 types, and the Real Type A among them, which describes to be as real as possible, is 12 kinds, the largest number of them. Therefore, real and natural pattern of peony is the favorite type in Korea, while rather emphasized pattern of peony is the more preferred pattern in China. And also Design Types are subdivided into 6 types again; There are 6 kinds of design type A, the largest part of Design Types. Patterns of Design Type A are most similar to real peony flowers, but more simplified than the Real Type A. This result also contrasted with the trend in China, where the Design Type C, expressed petals in detail was the favored pattern. Fourth, 9 kinds of unique types are found in Korean fabrics, especially Real Type M has not been shown on Chinese fabrics. Real type M, consisting of two parts, inner and outer, where two curve lines between two parts appear as antennas of a butterfly.

This study aims to analyze the typological characteristics of Alvar Aalto's library design. The unique characteristics of Aalto's architecture are the result of accommodating Modern architecture with regional qualities of Finland. Besides this, Aalto's typological approach in design made his color. The library might be the best example for understanding his design approach in that he showed 3 main features of type; wholeness, self-control and transformation. He established architectural types in his 30s through Viipuri public library and developed so-called fan type library plan. Aalto's library type is not a simple copy of exterior and interior form. It acts as a principle of configuration of his library architecture and applied to the building. Therefore, Aalto's library architecture can be recognized as the results of typological design approach in that it shows the transformation of type in according to factors including site, size, region and cultural tradition. In conclusion, Aalto's libraries reveal the typological characteristics in the field of building layout, dynamic space and the effective use of light.

This study analyzed the presentation trend of a checklist method for trench coat designs. Through this analysis, this study examined the flow of trench coat designs and presents future design directions. Research was conducted in the following method. A total of 1,307 female trench coat photos were selected from the photos presented in the top 4 collections from 2006 to 2011. These photos were used for analysis and frequency analysis was conducted. Among the checklist methods presented in trench coats, the modification type was most common, followed by the elimination type, conversion type, combination type, minimization type, addition type, and magnification type, respectively. Checklist methods were continuously presented even while increasing and decreasing according to the year and season. This showed that it was highly possible for checklist methods to be continuously applied in future trench coat designs. Generally, a high frequency of appearance was shown in 2010 and during the F/W season. According to the development direction of future trench coat designs applied with the checklist method, it is predicted that the modification type and the elimination type (which have generally displayed high appearance frequency) will be continuously magnified in the future. In particular, it is expected modifications in structural details (which have showed an upward trend in 2011) will be further magnified.

This study aims to analyze working hours of sprinkler heads when a fire occurs at an indoor gymnasium while sprinkler heads are installed in division of standard response type, special response type, and earlier response type. The fire scenario was designed under the assumption that the fire started from overheating of a heater in the indoor gymnasium has transferred on to a couch to spread. The analysis on the operation time of the standard response type sprinkler head, the special response type sprinkler head and the early response sprinkler head was conducted. The result showed that, in case of fire in a gymnasium, the time for opening of the heat sensor due to the heat from the fire varies by the type of the sprinkler head. When a special response type sprinkler is installed, it worked below the assessment standards. When an early response sprinkler head is installed, it worked appropriately according to assessment standards. Based on the results, we found that sprinkler heads will work properly when installed according to design relevant to laws and regulations. This means that there is a limit in installation of sprinkler heads based on the existing law-based design as for indoor gymnasiums. Again, we conclude that if sprinkler heads are installed based on design made through laws and regulations, more time will be needed for operation, making it highly likely to fail to stop a fire at an earlier point of time.

This paper presents a design methodology for magnetically tunable X-band E-plane type waveguide filters. The proposed design is based on using of quarter wavelength transmission line for compensating the negative length transmission line of end K-inverters of E-plane type waveguide filters. The derived formulae are applied for initial design and the correction method is also provided for final design by considering the frequency dependent characteristic of K-inverters. The analysis results of E-plane pype waveguide structure loaded with ferrite slab are obtained using the edge based finite element method including higher order mode effecets. It is shown that the unilateral finline E-plane type waveguide filter as well as the bilateral finline E-plane type waveguide filter achieves the the manetically tunable characteristic. The X-band experimantal results for bilateral and unilateral finline E-plane type waveguide filters agree well with the simulated data.

New Design configurations of the fighter aircraft igloo diffuser were studied based on the closed ventilation type in contrast to the conventional open distribution type. To validate the enhanced and safe performance, the exhaust flow patterns of the two igloo diffuser types were simulated by both experimental and computational approaches as design tools. Flow visualizations were conducted to investigate the exhaust flow patterns in experimental approach. In addition, the commercial code called Fluent was used to calculate flow field properties. Computational simulations provided detailed parametric studies that significantly reduced the amount of experimentation necessary to alter the design parameters of the existing fighter igloo diffuser. The closed ventilation type of the igloo diffuser was shown the better results.

Scattering of seeds is one of the problems in the hill- dropping planters with a roller-type metering device. For crops like rice, corns and beans, the hill-dropping is own better for a high yield than the drill planting. The roller type metering device has been used for the drill planters and has many advantages. However, it has a problem of scattering of seeds when they are placed on rows. In this study a method was developed to design the roller type metering device fir the precision hill-droppings. Design parameters were derived to configure completely the geometries of the roller and brush. The method was applied to the design of the metering device of the rice seeding machines. The field test showed that the metering device designed by the method made a better performance of seed placement than that made by the precvious one. The method also can be applied to the design of metering devices for the precise hill-droppings of other crops.

A studio type urban lifestyle housing was recently introduced as a new urban multi-housing typology. It was particularly created to meet the increasing housing demand of one-person households due to the population change and the shortage of housing supply. However, some concerns have been raised, because the government's policy has been focused on expanding housing supply by easing certain legal regulations in construction. Poorly planned and managed urban lifestyle housings might degrade living conditions for one-person households and ultimately harm urban environments. As such, this research is conducted to investigate the design characteristics of the studio type urban lifestyle housing from selected construction precedents in Seoul. Critical evaluations are made for the facilities and uses in site plans, unit plans, and shared public spaces. As a result, problem areas are found in the lack of design varieties, privacy protection in units, control of natural environment conditions, and the absence of community spaces. Improvement strategies can be suggested by comparing with some overseas' housing precedents: Design variations can be extended through flexible structure, facility, and furniture systems. Privacy and natural environment can be controled through the integration of interior space configurations and exterior envelope systems. The housing policy needs to be reconsidered to improve a variety in design, residents' social interaction, security, and management. Thereby, the studio type urban lifestyle housing should be holistically approached in terms of design and policy to enrich urban living experiences by residents and communities.
