The aim of this study was to clarify the arrangement of the zygomaticus major muscle, and to describe morphology of zygomaticus minor muscle. After a detailed dissection, the zygomaticus muscles were observed in 66 embalmed cadavers. It was found that the insertion of zygomaticus major was divided into superficial and deep bands(42/70, 60%). Zygomaticus minor was inserted not only upper lip also alar portion(5/54, 9.2%). The arrangement and insertion patterns of the zygomaticus muscles in this study are expected to provide critical information for understanding or smile pattern and treatment or fold.

The bluegill Lepomis macrochirus is an invasive species, not native to Korea, introduced for aquaculture. This species is ranked as a new top predator due to its massive aquatic carnivorous and herbivorous nature by acute vision and the absence of a natural enemy. The visual cells of the retina of L. macrochirus are composed of short single cones and equal double cones and long and bulky rods by light and electron microscopes. In particular, the cones show a regular square mosaic arrangement. This pattern is widely considered as a strong predator. With regard to the visual system, this mosaic pattern may closely be related to a dynamic visual acuity to track and hunt prey.

We analyzed carbonization pattern and crystal structure of polyvinyl chloride wire by thermal stress. Copper that is oxidized at normal temperature is a reddish brown. If under the thermal stress range of 500 to 700 [$^{\circ}C$], carbonization and exfoliation occurrence. Section structure of electric wire is same as arrangement of particle in metallograph analysis. But, as thermal stress increases, size of particle is enlarged. Electric wire displays elongation structure in SEM image analysis and elongation structure collapses when receive thermal stress at 300 [$^{\circ}C$]. In EDX analysis, we get the spectra of CuL, CuK, OK, and ClK. FT-IR analysis was shown new spectra with in range of $1,440{\sim}1,430\;[cm^{-1}]$, 1,340 [$cm^{-1}$], 1,240 [$cm^{-1}$].

The present study has numerically investigated two-dimensional flow over three circular cylinders in an equidistant side-by-side arrangement at a low Reynolds number. For the study, numerical simulations are performed, using the immersed boundary method, in the range of g* < 5 at Re= 100, where g* is the spacing between two adjacent cylinder surfaces divided by the cylinder diameter. Results show that the flow characteristics significantly depend on the gap spacing and a total of five kinds of wake patterns are observed over the range: modulation-synchronized (g* (equation omitted) 2), inphase-synchronized (g* (equation omitted) 1.5) , flip-flopping (0.3 < g* (equation omitted) 1.2) , deflected (g* (equation omitted) 0.3), and single bluff-body patterns (g* < 0.3). Moreover, the parallel and symmetric modes are also observed depending on g* in the regime of the flip-flopping pattern. The corresponding flow fields and statistics are presented to verify the observations.

A numerical study has been conducted to investigate the effect of tube arrangement on the heat transfer and the pressure loss for cross flow heat exchangers. By defining a transverse deviation factor, ${\varepsilon}_t=l_T/S_T$, the flow pattern and the heat transfer characteristics are compared for selected ${\varepsilon}_t$ values of 0.0(in-lined), 0.1, 0.2, 0.3, 0.4, 0.5(staggered) by using a commercial software. Computational domain includes 1 pitch in the transverse direction and 5 pitches in the flow direction with due periodic boundary conditions.

The flow around two rectangular cylinders with aspect ratio of 0.5 in a tandem arrangement, was investigated using pressure measurements (in a wind tunnel) and flow visualizations (in a water tunnel) in the range of P/h from 0.6 to 4.0. Four flow patterns were identified, and processes of shear layers wrapping around, the shear layer reattachment, vortices wrapping around and vortices impingement, were observed. Mean and rms pressure distributions, flow visualizations and Strouhal numbers were presented and discussed. The paper revealed that the variations of Strouhal numbers were associated with the shear layers or vortex interference around two cylinders.

Clothes show not just the different social status of people, but the ideology and value of former society through pattern, colour, materials, shapes, etc. The purpose of this article is to fill the academic blank of this part by researching the pattern of fabric design in Jing Pai(Beiing style) and Hai Pai(Shanghai style) cheong-sam during the period of the Republic of China. The contrastive analysis of regional pattern between Jing Pai and Hai Pai cheong-sam expect to provide the theoretical basis for the former fashion designers and scholars. There are three approaches in the article: Data collection method, comparison method and Combining theory with practice method as film. Regarding components of pattern, both Jing Pai and Hai Pai cheong-sam have mostly single or composite pattern like plants. Further the most of Jing Pai cheong-sam pattern is traditional flower pattern. But Haipai cheong-sam patterns have some western flower pattern. Beside that, it have some geometry pattern. Regarding arrangement of the pattern, both cheong-sams have scattered dot style, the border style, and pictures style. But continuous type of Jing Pai cheong-sam is less while Hai Pai cheong-sam is the most. Comparing Jing Pai cheong-sam color of patterns in "Moment in Peking" is unadorned and types are simple as chinese traditional clothes; However, "In the Mood for Love" introduces us various material colors, new types of patterns and extraneous characteristic geometry patterns of Hai Pai cheong-sam. Generally speaking, the main characteristic of Jing Pai cheong-sam is traditional and conservatism. It keeps Chinese traditional pattern and culture to the most extent. However, Hai Pai cheong-sam are confluent and open with absorbed external culture and techniques which are endowed new artistic color.

The purpose of this study is to investigate types and formative characteristics of 'Seon' represented of costume in Water-moon Avalokitesvara of the late Koryo Dynasty. The results were as follows; 'Seon' has two main types, Standard and Decoration types. In the former type, Seon has not any decoration. While, in the latter, Seon is added with decorations. Here, Seon of decoration type can be reclassified into two types, same color and pattern and different color and pattern. Seon most appeared in the Water-moon Avalokitesvara had the type of Decoration, especially different color and pattern. Patterns used for Seon were complex in its composition type and filling in its arrangement style. Seon was mainly used to Guneui(裙衣) and Samkaksika(僧脚崎). For the color combination of Seon, the combination of similar colors was most often used and that of same color was somewhat frequently done. Regarding costumes aesthetic characteristics in accordance with the type of Seon, those costumes appeared natural and elegant when their Seon was Standard in type, natural and brilliant when same color and pattern in type and artificial and brilliant when different color and pattern.

Micro electro mechanical systems (MEMS) and precision machines require excellent friction and wear characteristics to improve energy efficiency generated during sliding motion. In this study, DLC thin film with high hardness and low friction was deposited on STS304 substrate material by CVD method, and dot-shaped convex and concave micropatterns were fabricated by photolithography process. The diameter of the pattern was 20 ㎛, the pitch was 40 ㎛, and a pattern having a mesh type arrangement was fabricated and an abrasion test was performed. The results of the wear test on the micro pattern confirmed that the friction coefficient characteristics were improved compared to STS 304 and DLC thin films. In addition, in this result, the micro-pattern showed 11.4% more improved friction coefficient than the DLC thin film. The friction coefficient characteristics for convex and concave patterns of the same size showed almost similar results.

본 연구는 TV음악쇼 프로그램에서 가수 등의 공연자를 중심으로 배경 디스플레이로 사용되는 LED백드롭(backdrop)의 모션그래픽 이미지 조형구성을 분석하였다. 모션그래픽 LED 화면은 평면조형으로 구성되는데, 백드롭의 배경으로써의 기능이 공감각과 시각요소의 감성전달이라는 목표가 있는 것이므로, 감성전달 요소가 되는 컬러와 모션 방향과 속도에 대한 감성적 개념을 분석하였다. 감성전달 요소 중 그래픽 조형에 대한 분석으로는, 이를 이루는 형의 종류와 응용요소를 구분하고 그러한 요소들이 음악 곡의 전개인 인트로, 벌스, 브릿지, 코러스 부분에서 어떠한 모션 패턴과 배치가 이루어지는지 그리고 남성과 여성 공연자의 배경으로써 어떠한 디자인 특징이 있는지 연구하였다. 사례연구로, 모션그래픽 배경이미지 디자인이 활발히 이루어지는 지상파TV 3사의 청소년 대상 음악 순위프로그램을 대상으로 하였으며, 곡 전개에 따라 주로 디자인 되는 조형의 종류와 모션 패턴 그리고 모션 배치 유형을 도출하였다.
