The purpose of this thesis was to design and develop restaurant uniforms for Yeosu and Suncheon-City using local cultural resources by investigating the present situation of restaurant uniforms. The study was conducted through literature review and practical research on uniform designs. The practical research included investigating and analyzing the recent uniform designs of 60 spots in both cities and the preference of local cultural resources, finally suggesting eight restaurant uniform designs and four original samples. It was found that most workers in both cities wore shirts and pants or aprons as uniforms and also that the restaurant uniforms had many problems, such as poor designs, functionality, and the lack of local characteristics. According to these results, a design concept called 'Colorful Night Sea' was built for Yeosu using a design motive of a Yeosu Expo symbol, a Big-O Show shape, and Dolsan Gat flowers. For Suncheon-city, a design concept called 'A Rural Landscape' was built using a design motive of Nagan Eupseong and a field of reeds in Suncheon Bay. The restaurant uniform items included a top (shirt or blouse), pants, apron, and headdress in both cities. This study is meaningful as it helped improve the local image and economic situation, by proposing distinct uniforms designed by using local cultural resources.

This study investigated the correlation between consumer's buying habits and food styling visual elements. Differentiated and original techniques were used to determine whether or not visual elements in tteok menus reflect the aesthetic needs of consumers without altering the nutrition of tteok. The targeted tteok cafes were in Jeonju Hanok Village, which is a tourist attraction in Korea. First, sub-factors of food styling visual elements applied to tteok $caf{\acute{e}}$ menus such as shape, size/volume, color, and texture all had significantly positive effects on customer satisfaction, proving that food styling visual effects applied to tteok $caf{\acute{e}}$ menus have significant effects on customer satisfaction. Second, sub-factors of food styling visual elements applied to tteok $caf{\acute{e}}$ menus all had significantly positive effects on buying habits. Third, customer satisfaction of menus had a significant effect on buying habits, as proven by previous studies. Fourth, the effects of customer satisfaction on the relationship between food styling visual factors applied to tteok $caf{\acute{e}}$ menus and buying habits were investigated.

A new deformation process termed "continuouis confined sup shearing" (CCSS) has been developed for shear deformation of metallic sheets. The tools of CCSS were designed to provide a constant shear deformation of the order of 0.5 per pass while preserving the original sheet shape. In order to clarify the evolution of texture and microstructure during CCSS, strips of the aluminum alloy AA3004 were deformed by CCSS in up to three passes. FEM results indicated that CCSS provides a quite uniform shear deformation at thickness layers close to the strip center, although the deformation is not homogeneous in the die channel, in particular at the surface layers. The rolling texture of the initial sheet decreased during CCSS, and preferred orientations along two fibers developed. However, with an increasing number of CCSS passes the deformation texture did not develop futher. The evolution of annealing textures depended on the number of CCSS passes. A strong {112}<110> component in the deformation texture led to the formation of a strong {111}<112) orientation in the annealing texture. Observations by TEM and EBSD revealed the formation of very fine grains of ∼1.0$\mu\textrm{m}$ after CCSS.

In order to obtain dynamic behaviors of complex structures, it demands large amounts computational cost and time to perform the numerical analysis. The model reduction method helps these problems by dividing the full model into primary and unnecessary parts. In this research, we perform the modal analysis using the dynamic substructuring method, which is one of the model reduction methods, in order to obtain the dynamic characteristics of the cylindrical structures efficiently. To select the master degrees of freedom (dofs), we consider the mode shapes of the cylindrical structures. And then, we identify the validity of the dynamic substructuring method by applying the method to the simple cylinder and core support barrel (CSB) which is one of the reactor internals with the cylindrical shape. The results demonstrate that the dynamic characteristics from the dynamic substructuring method are well matched with the original method.

Paedomorphosis is the retention of juvenile morphology at maturity and is important in generating evolutionary change in domestic species and species in the wild. This preliminary study compared morphological characteristics of seven domestic cat pure breeds and felid species from around the world. An original procedure based on elliptical Fourier (EF) methods was applied to head lateral views of specimens and were assessed in order to analyse head profile. For comparative purposes three domestic kittens of different ages and three species of genus Lynx were also used. EF descriptors, allowed for the quantification of the head profile. Using the Fourier transform, reconstruction of the mean head profile revealed that there was a general shape difference between wild cats, domestic cats and kittens. Results suggested that variability in head profile differentiate quite well between adult cats and kittens, but domestic and wild cats appeared grouped into a similar cluster. The similarity between breeds can thus be attributed more to the general head profile than to flatness, i.e. to the general conformation rather than facial profile. Therefore, no effect of paedomorphism on the studied breeds can be undertaken. The present approach opens interesting ethnological perspectives for the aloidic characterisation for domestic breeds.

Pipe section of bending part at the arch type pipe-house showed an ellipse with oblateness of 0.076 on the average. Flexural rigidity of bending part decreased by average 6.3% than that of an original round shape section. The deflection of arch type pipe-house measured by model experiments showed much bigger than the result of structural analysis. In case of arch type pipe-house, we supposed that the decrease of flexural rigidity for the bending part of pipes had an effect on deflection of roof under the working load. This effect should be considered in the structural analysis. Bending resistance of gable type pipe-house used a prefabricated connector which developed in this study showed about $1.5{\sim}1.8$ times stronger than that of the existing arch type or gable type processed bending. Therefore, we supposed that the gable-roofed prefabricated pipe-house is safer than arch type or bent gable type in case of heavy snowfall. According to house scales and section properties of steel pipe in use, safe snow depths and rafter intervals were presented for design of gable-roofed prefabricated pipe-house. Their standards were established in the range of the durable models recommended by RDA, and the comparative examinations were conducted by means of structural analysis. It was evaluated that the developed greenhouse model had a high applicability in the field.

The history and culture of using Zhu to help take food in China is a focal question in contemporary Chinese academic circle and leads to various conflicting ideas. This article, based on original historical documents, archaeological findings, cultural relic authentication, field investigation and the author's long-term thinking, comes up with a series of new conclusions. Firstly, Zhu emerged and developed along with cooked food and granular food served in bowls; secondly, there had been a period of using a single Zhu in China's history before two Zhus being used simultaneously; thirdly, the development of Zhu culture went through five historical periods, namely the former form, the interim form, the Jia form, the Zhu form and chopsticks form. In addition, the author gives out his unique viewpoints on some other relevant questions, including the Zhus which can be dated back to the Neolithic Age unearthed at Longqiuzhuang in Jiangsu province, Jiangzhai in Shanxi province etc, and the bronze utensils in the shape of Zhu unearthed in 1934 at Yin Dynasty ruins in Henan province.

The volume expansions of $Ti_{0.95}Zr_{0.05}V_{0.4}Mn_{1.45}Fe_{0.1}Cr_{0.05}$ alloy during hydrogenation with various conditions have been investigated. The theoretical volume expansion measured with XRD for this alloy with hydrogenation was 21%. The apparent volume expansion of this alloy ingot with hydrogenation was composed of two effects. One is a hydrogenation and the other is a pulverization. The apparent volume of free alloy powder was 1.8 times greater than that of an ingot, implying the pulverization effect on the apparent volume expansion is 80%. The apparent volume expansion of the alloy ingot with hydrogenation under a unconstrained condition was about 80 (${\pm}15$)%, much smaller than that of free alloy powder which expected as 118%. In addition, The apparent volume expansion of the alloy ingot with hydrogenation under a constrained condition(Al container) was about 50%, much smaller than that of the unconsrained. This reduced apparent volume expansion of the alloy ingot could be attributed to an arrangement of alloy powder keeping its original shape of the ingot even after hydrogenation.

This study aimed to suggest more appropriate and accurate festival costumes based on a comparative analysis on various reproduced costumes and a period review of traditional festival costumes. In particular, the comparative analysis examined festival costumes which appeared in Korean and Japanese festival parades during the Baekje Period. The Baekje Cultural and Sacheonwangsawasso Festivals were examined. A literature review as well as field research and digital restorative techniques were used in the study. The reproduction patterns of Baekje costumes from both festivals were compared with original Baekje costumes, demonstrating several differences in the configuration, material, color, and shape of the costumes in addition to the way they were worn. Based on the comparative analysis, Baekje costumes used in Festivals were grouped into three categories: King's Costume, Queen's Costume, and Government Official's Costume. Dress sketches and 3D illustrations also have been presented.

The Seismic probabilistic risk assessment (SPRA) or seismic margin assessment (SMA) have been used for the seismic safety evaluation of nuclear power plant structures and equipments. For the SPRA or SMA, the reference response spectrum should be defined. The site-specific median spectrum has been generally used for the seismic fragility analysis of structures and equipments in a Korean nuclear power plant Since the site-specific spectrum has been developed based on the peak ground motion parameter, the site-specific response spectrum does not represent the same probability of exceedance over the entire frequency range of interest. The uniform hazard spectrum is more appropriate to be used in seismic probabilistic risk assessment than the site- specific spectrum. A method for modifying the seismic fragility parameters that are calculated based on the site-specific median spectrum is described. This simple method was developed to incorporate the effects of the uniform hazard spectrum. The seismic fragility parameters of typical NPP components are modified using the uniform hazard spectrum. The modification factor is used to modify the original fragility parameters. An example uniform hazard spectrum is developed using the available seismic hazard data for the Korean nuclear power plant (NPP) site. This uniform hazard spectrum is used for the modification of fragility parameters.
