Clothing as one of elements of culture has been interwoven with cultural diffusion, and accompanied the most visible change. In this paper, it was focused that the process and the characteristics of western clothing adop-tion of Korea from 1876 to 1945 corelating with cultural diffusion theory. They were analyzed through the change of clothing reformation system by government, school uniform, and social phenomenon. The finding of this paper were as followings; 1. The process of western clothing adoption was forcibly demanded by Japan, therefore influenced by Japan. 2. The clothing reformation which was forced to accept western style was confronted by complex of cultural, psychological and economical resistance. 3. The fashion leaders of this period were Korean students studying abroad, diplomatic officials, members of the armed forces, government officials, students of western educational systemed school, and lady of evangelist. 4. Man adopted western clothing earlier than woman. 5. Western clothing adoption was took precedence in case of formal wear, diplomatic official's attire, military uniform, and school uniform. 6. In this process, we can find 'transculturation' by Malinowski and 'reinter-pretation' by Herskovits. 7. This process was a kind of 'reorientaion'. 8. The change of clothing which was affected by the tradition, for example, robe for the ancestral rites was evolutionary than others. 9. Clothing elements based on mental or internal characteristics like which clothing was hardly changed by compulsion or extortion. 10. The external trends of clothing change during this period were simplicity, utility, and decrease of status symbols.

This study is normal orientation technology of slit coating equipment to improve the quality of curved displays. Currently, the demand for curved displays is increasing significantly due to advantages such as screen immersion or design in various industries. Accordingly, changes in the display coating process are essential. In the curved display coating process, unlike the existing flat coating process, the nozzle must be rotated along the curvature of the curved surface to spray the coating solution. The coating solution must be applied while maintaining a uniform thickness. If the thickness of the coating liquid applied to the target surface is non-uniform, the quality of the product may be degraded such as image quality deterioration and light spreading. This paper presents technology and experimental results for keeping the nozzle of slit coating equipment perpendicular to the curved surface and is expected to contribute to the quality improvement of curved displays.

A uniform is generated in the course of confirming a singular mode of dress that is adopted by a community for a specific purpose. In particular, women's uniform has a close relations to their position in the community they belong to. And women's uniform has closely been associated with finding ways into their communities over the centuries, and is part of women's development process. Women's history of using organized uniforms has not been longer than men's. Their realm of activities began to be enlarged due to the World War, and women's uniform has gradually settled down and moved toward diversity. The origin of many uniforms worn by today's women can be traced back to the end of the last century, and this fact indicates that women started to find their ways into many new fields at that time. There has been a lot of changes until current women's uniforms come out. It's intended in this study to contribute to designing more creative and productive women's uniform, by taking a careful look at typical early uniforms for service personnels, nannies, nurses and soldiers that are an indication of their work and working environment.

Based on Nonlinear Finite Element Analysis (NFEA), this paper focuses on the bi-axial ultimate strength of typical bottom structures under corrosion. On one hand, uniform and not simultaneous corrosion across different structures is introduced, and surrogate models by Gaussian Process (GP) are built for both longitudinal and transverse cases individually, and corresponding probabilistic characteristics are investigated; meanwhile, corrosion effects on interaction between bi-axial stresses at ultimate state are studied. On the other hand, non-uniform localized pitting corrosion of normally distributed circular shapes is introduced, and different pitting corrosion densities are considered; structural bi-axial ultimate strengths under pitting corrosion are studied, and the results are compared with that from equivalent uniform corrosion; the probabilistic characteristics of structural ultimate strength in life cycle are studied; finally, the ultimate strength under randomly distributed pitting corrosion is compared with results from normally distributed pitting and uniform corrosion under various boundary conditions.

In this paper, we consider fuzzy random sets as (measurable) mappings from a probability space into the set of fuzzy sets and prove a uniform strong law of large numbers for sequences of independent and identically distributed fuzzy random sets. Our results generalize those of Bass and Pyke(1984)and Jang and Kwon(1998).

The baker transformation is an ergodic transformation defined on the half open unit square. This paper considers the limiting behavior of the partial sum process of a martingale sequence constructed from the baker transformation. We get the uniform law of large numbers for the baker transformation.

Elongation rolling process is an intermediate process to make the uniform thickness and uniform surface roughness during producing seamless pipes. The thickness and surface roughness of seamless pipes are generally affected by the distance of rolls and guide shoes, the roll shape, and its cross angle. In this study, finite element analysis for shape forming process is based on the analysis model of elongation rolling mill with guide shoes. This paper shows how the cross angle of the roll, the rolling rpm, and the distance of the guide shoe influence on the outer diameter and the thickness of seamless pipes. The rolling rpm did not give much influence on outer diameter.

To fabricate uniform and reliable thin gold stripes that provide low-loss optical waveguides, we developed a novel liftoff process placing an additional $SiN_x$ layer under conventional photoresists. By patterning a photoresist and over-etching the $SiN_x$, the photoresist patterns become free-standing structures on a lower-cladding. This leads to uniform metal stripes with good reproducibility and effectively removes parasitic structures on the edge of the metal stripe in the image reversal photolithography process. By applying the newly developed process to polymer-based gold stripe waveguide fabrication, we improved the propagation losses about two times compared with that incurred by the conventional image-reversal process.

This study investigates the durability of a two-passenger bicycle frame under non-uniform fatigue load. The bicycle frame of Model 1 installed with reinforcement support has a 20% lower maximum equivalent stress than the existing Model 2. Model 1 has a maximum total deformation that is less than half that of Model 2. Model 1 has a higher maximum fatigue life than Model 2. In addition, Model 1 has lower fatigue damage than Model 2. Thus, the bicycle frame of Model 1 installed with reinforcement support can be described as safer, as it offers more strength than Model 2. Applying this result to the design of a real two-passenger bicycle frame under non-uniform fatigue load can effectively prevent fatigue damage and improve durability.
