The primary focus of this thesis is to look at Scythai's historical, geographical and ethnologic background in order to understand Scythai's garment types and styles as described in Scythai-related documented records, previous studies and excavated artifacts. Based upon this, another objective lies in comparing and contrasting this information with ancient Korean garments to identify what kind of relationship exists between the two. The result from this study's objectives is summarized as follows. Firstly, ancient Korean and Scythai share similarities in art work, craftwork, accessories and the like, which allows us to make a guess at the relationship between ancient Korea and Scythai of that time. Secondly, Scythai garments are based on the tight and well-fitted Caftan Yugoje, which is tightly fit to the body, as well as including garments similar to the drapery Kiton and Tunic found in ancient Greek garments, from which can be seen that the garment of culture medium passing between the East and the West had nomadic horse-riders' ethnic characteristics and Eurasian characteristics. Thirdly, ancient Korean Scythai garments were found to have homogeneity in their garment culture in that northern nomadic cultural district's Hobok-Goseupje, i.e., open-front Caftan Jeogori and pants called Sangeuihago is its basic with a triangular cone hat shape (transformed hat) and boots, which is the basis for considering that ancient Korea exchanged culture with Scythai, who once lived as active northern nomads. However, it can also be seen that ancient Korea and Scythai garments differed in form depending on region, weather, culture, custom and the like. As such, Scythai and ancient Korea have an aesthetic bond because northern nomads and Scythai exchanged their cultural traits of the times. The evidence supports this idea as it seems that the characteristics of garments that can be considered to be Scythain in style are also commonly discovered in ancient Korean garments.

목적: 콘택트렌즈의 피팅에 따른 눈물 층의 두께, 렌즈의 Dk 값 및 두께 변화가 각막에 유입되는 산소확산에 미치는 영향을 고찰하였다. 방법: 확산에 관한 Fick 법칙 및 연속법칙을 사용하여 액체(눈물)-CL-눈물 층을 통하여 각막으로 유입되는 산소 flux 및 각막 표면의 산소 분압을 계산할 수 있는 일련의 방정식을 세우고 이들 식에 의거하여 피팅에 따른 눈물 층의 두께, 렌즈의 Dk 및 두께 변화가 각막에 유입되는 산소 flux에 어떠한 영향을 미치는가를 예측하였다. 결과: 본 모델을 사용하여 적절한 피팅 조건에 부합하고 또한 각막 표면의 산소 분압이 보장되는 렌즈의 Dk 및 두께를 결정할 수 있었다. 결론: 대단히 높은 Dk 값을 지닌 렌즈라도 너무 flat 또는 tight하게 피팅된 경우 렌즈의 주변부와 각막 사이 눈물 층의 간격이 커짐으로 인하여 각막에 도달하는 산소 flux 및 각막표면의 산소 분압이 급격히 감소될 수 있다.

Presented in this paper was to evaluate and improve the usability of a web-based logistics information system. The system was developed for the domestic company to track and monitor its own transportation vehicles and for the customers to check the current location of their packages by using Global Positioning System (GPS) and Short Massage Service (SMS). Since the initial system was developed under a tight schedule set by the company, the system designers and programmers did not focus on the usability of the system but on the functionality. Consequently, some usability problems of the system were discovered during the heuristic usability evaluation. This study was required to solve these usability issues. Usability problems of the initial system were identified and analyzed, and the user's requirements for the system were re-evaluated to meet the company's expectation. Several alternative designs were developed by fitted guidelines and then a updated system was developed. The updated system had an empirical usability test to find how much the initial system was improved from the heuristic evaluation. Two kinds of data were gathered during the tests: objective (completion time and number of errors) and subjects' preference. Data showed the updated system is better than the initial system in terms of usability. Presented in this paper includes introduction of the Usability evaluation, usability engineering process applied in this research, alternative design of GUI, usability test and results.

To analyze recent changes in designer-specific garment composition, detail, and design elements of jackets, we classified jackets from the Paris Haute Couture Collection from 2000 S/S to 2019 F/W according to their designers and examined their characteristics. Our analysis of the jackets by Armani, Chanel, Dior, Jean-Paul Gaultier, and Valentino shows that the hour-glass silhouette was most common in Armani, Chanel, Dior, Jean-Paul Gaultier and Valentino jackets; Chanel used more straight silhouettes compared to other designers. Most jackets, regardless of the designer, had midlength waist-to-bottom, tight sleeves fitted to the body, natural shoulder shape, and solid color. Moreover, woven fabric was the most common material. Jackets with no collar were the most common for Armani, tailored collars for Dior and Jean-Paul Gaultier, and standing collars for Chanel and Valentino. For the closure method, Armani used hook-and-eye, Chanel, Jean-Paul Gaultier, Valentino used button closures, and Dior used snap closures the most. New design attempts by designers are bringing details and design elements together. In an era characterized by an abundance of designs and frequent replacement of each brand's creative designers, it is important to create and maintain a brand's unique design identity and philosophy that can meet consumers' elevated standards, which tend to be biased towards new and stimulating designs due to the development of the IT industry.

The purpose of this study was to analyze and compare the shapes, colors, patterns, and hairstyles of Qipao worn by heroines that were reconstructed over times, in a Chinese TV Drama set in the 1930s and televised in 1980 and remade in 2007. We investigated how the Qipao was reinterpreted. The results were as follows. First, in televised in 1980, Qipao borrowed the characteristics of Jing Pai Qipao, which became popular in Beijing. Jing Pai Qipao was characterized by a roomy and loose silhouette that does not expose a body line, Chinese traditional 5 colors, simple plain patterns and Chinese traditional flower patterns. For hairstyle, twist and permanent wave styles that were popular in the Republican Period were very common. On the other hand, in televised in 2007, Qipao was a Hai Pai style that was very popular in Shanghai in the 1930s. Hai Pai Qipao was characterized by a tight silhouette fitted to the body, various colors such as purple and beige other than the 5 colors, Western flower patterns and modern geometric patterns. Hairstyle was changed from bang hair to a permanent wave. Second, while had a modern reinterpretation of Jing Pai Qipao that was very popular in Beijing, rather than Hai Pai Qipao that became popular in Shanghai in the 1930s, used Hai Pai Qipao that was popular in Shanghai in the 1930s. In particular, demonstrated how the mass media should reinterpret past clothing by thoroughly studying and reflecting Shanghai Qipao in the 1930s and adding viewers' aesthetic taste of 2007 without damaging an original. Moreover, it confirmed that clothing can function as language and symbol within the mass media by connecting the color and pattern of Qipao with characters' traits and the plot. It suggests that was more advanced than filmed in the 1980s. The findings of this study might provide useful data to costume designers who reinterpret costumes from a new angle.

주기적으로 변하는 압력이 loose 또는 tight fitting 상태의 콘택트렌즈와 같은 diaphragm에 작용하여 진동이 발생하는 경우 diaphragm의 가장자리(edge)는 단순지지(simply supported) 또는 고정(rigidly clamped) 상태로 가정할 수 있으며, 이러한 가정하에 diaphragm의 진동을 해석할 수 있는 미분방정식과 그 해를 구하는 컴퓨터 프로그램을 작성하였으며 이 컴퓨터 모델을 사용하여 진폭 및 출력을 예측하고 diaphragm의 반경 및 두께, damping, 작용하는 압력의 진동수 등 제반 변수가 진동에 미치는 영향을 모사하였다. 외부 압력의 진동수가 어떤 범위 이상에서는 diaphragm의 파형은 한 개의 peak를 가지는 원호형에서 2개의 peak를 가지는 파도형으로 전환되며 이 때 진동수가 증가함에 따라 diaphragm의 바깥 부분의 peak가 안쪽 peak보다 높아지는 것을 알 수 있다. 이러한 경향이 시작되는 진동수는 diaphragm의 가장자리가 단순지지된 경우가 clamped 된 경우보다 훨씬 낮다. 단순지지된 diaphragm의 진동은 고정단 진동에 비하여 기본 공진(fundamental resonance)이 월등히 낮은 진동수에서 발생하며, 따라서 저주파 영역에서는 진동수가 낮아질수록 두 진동간의 진폭차가 커지지만 고주파 영역에서는 그 차이가 미미하게 된다. 또한 단순지지 diaphragm의 진동의 특징은 진동수의 증가에 따라 여러개의 공진(harmonics)이 발생하지만 전체적으로 진폭은 급격하게 감소한다. 그러나 저주파 영역에서 단순지지 진동의 진폭이 크다고 해도 출력은 낮기 때문에 diaphragm의 진동에 따른 출력(power)은 특정 진동수에서 하나의 주 peak를 갖는다. 단순지지된 diaphragm이 진동할 때 diaphragm의 출력 공진진동수는 두께가 증가할수록 감소한다. 이 경우 형성되는 harmonics의 출력은 기본공진의 강도에 비해 현저하게 떨어지는 것이 진폭의 경우와 대조적이다.
