연구의 목적은 자연의 소중함을 깨닫게 된 코로나 시대를 거치면서 자연의 다양한 모티브 중에서 개체 수의감소가 환경오염의 척도로 상징되는 나비, 곤충 등의 표현 빈도가 증가하는 것에 주목하고자 하였다. 본 연구의 범위는 2019년부터 2023년까지의 패션컬렉션을 대상으로 온라인 <보그>지(www.vogue.com)의 시즌별 패션컬렉션 패션쇼 사진과 인터뷰 기사로 한정하였다. 연구 결과 185개의 나비모티브 의상이 나타났으며 평면적 표현방식의 유형으로는 디지털 프린팅 기법이 가장 많이 활용되었다. 이와 함께 퀼팅, 자수, 비딩 등의 기법들이 나비의 평면적 모티브를 표현하는 기법으로 많이 등장하였다. 입체적 표현 유형으로는 3D 프린팅, 레이저 컷팅, 코사지 기법, 드레이핑 기법을 사용한 유형들이 비슷한 비중으로 나타났다. 표현된 나비 모티브는 추상적인 표현보다는 나비의 형태를 그대로 묘사한 사실적인 디자인이 더 많았음을 알 수 있었다. 결론적으로 최근 5년간의 나비모티브 패션디자인은 과거의 나비모티브 패션에 비해 환경에 대한 메시지를 강하게 담고 있음을 알 수 있었다. 단순히 나비의 형태적 아름다움과 화려한 디자인 요소를 넘어서 친환경 메시지를 전달할 수 있는 상징적 의미가 큰 모티브임을 확인할 수 있었다.

The life cycle of butterflies is closely related to the growth of food plants and, through a prolonged coevolutionary process, has undergone an ecological adaptation. So, it is important that control the egg-laying number and place to secure enough food plant by female adult to guarantee the survival of the larvae. To study whether oviposition control of the Luehdorfia puziloi takes into greater consideration food plant leaf biomass or leaf abundance, correlation among the egg cluster size, the leaf size, and the number of leaves around egg clusters was investigated. According to the results, the egg clusters size exhibited positive correlation with the leaf size of food plants on which eggs had been laid but did not do so with the number of surrounding leaves. In addition, the number of egg clusters laid exhibited positive correlation with the number of surrounding food plant leaves but not with the leaf size on which eggs had been laid. Consequently, for the Luehdorfia puziloi, the females' recognition of the leaf size seems to be the most important factor in the egg cluster size, and the number of egg clusters had positive correlation with food plant density per unit area.

During thousands of years the people of china have not only created the brilliant cul-ture with a world reputation but also brought about an abundant treasury of paramountly beautiful hairdo fashions beyond comparison. Hair styles are an important symbol of the ma-terial and cultural civilization of a certain his-torical period. In Dang Dynasty the country was unified the economy was properous and the political situation was relatively stable. These spelt the solid foundation on which the rich and colourful varieties in the hair styles of women emerged. The numerous hair fashions in Tang Dynasty woman folk could be summed up into three catagories-high bun hanging bun and flat bun. Of course like the garments hair fashions are also the marks for the social status of the women in the feudal society. The hairstyle of the women of the Song Dynasty still followed the fashion of the later period of the Tang Dynasty the high bun be-ing the favoured style. To dress this type of high bun switches were generally used sometimes fashioned in to switch buns of various shapes coiled directly on top of the head. Women from rich families however usually had hairpins and combs made into the shape of flowers birds phoenixes of butterflies to be pinned on top of the buns.

The purpose of this study is to comparatively examine techniques and expressive characteristics of batik by focusing on the work of DanZhai and that of ZhenNing Buyi. We collected 50 pieces of batik each from Miao and Buyi in Chinese GuiZhouSheng and then analyzed their colors and patterns. The findings show that most of Miao's batik had deep and soft tones, while that of Buyi most often had blackish tone since the number of dyes in the latter is higher than that in the former. Miao often used patterns expressing animals or animals and plants, while Buyi frequently used geometric ones. An examination of specific motifs demonstrated that butterflies, fish, and flowers were most often used by Miao, while dots, vortexes, lines, and lozenges were frequently utilized by Buyi. For expressive techniques, both Miao and Buyi commonly used simple stylized expression or complex expression combining stylized and geometric techniques. Maio's motifs were often decoratively expressed with delicate curves, while Buyi's motifs had simple structures, so pictures were neatly expressed with thick lines and wide and simple planes. For the composition of the motifs, incomplete symmetry between top and bottom and between left and right often appeared in Maio, while in Buyi complete symmetry was frequently shown.

We investigated the species richness of lepidopteran insects (excluding butterflies and microlepidoptera) of Mt. Seungdal-san, Muan-gun, Jeollannam-do, Korea, from 2003 to 2005 using two portable light traps. A total of species comprised 423 species belongs to 17 families were identified. The family Noctuidae with 209 species was dominant in the area followed by Geometridae with 132 species. Based on the number of individuals collected, Geometridae was the highest mostly due to an ennomine species (Alcis angulifera). Monthly fluctuations of moth species richness present an M-shaped curve with two high peaks at June and August. Comparisons of species diversity of yearly captures revealed that the diversity of 2003 was higher than that of 2004, but the diversities of between 2003 and 2005, and between 2004 and 2005 were no different.

In this paper, a high throughput multiple transform architecture for H.264 Fidelity Range Extensions (FRExt) is proposed. New techniques are adopted which (1) regularize the $8{\times}8$ integer forward and inverse DCT transform matrices, (2) divide them into four $4{\times}4$ sub-matrices so that simple fast butterfly algorithm can be used, (3) because of the similarity of the sub-matrices, mixed butterflies are proposed that all the sub-matrices of $8{\times}8$ and matrices of $4{\times}4$ forward DCT (FDCT), inverse DCT (IDCT) and Hadamard transform can be merged together. Based on these techniques, a hardware architecture is realized which can achieve throughput of 1.488Gpixel/s when processing either $4{\times}4\;or\;8{\times}8$ transform. With such high throughput, the design can satisfy the critical requirement of the real-time multi-transform processing of High Definition (HD) applications such as High Definition DVD (HD-DVD) ($1920{\times}1080@60Hz$) in H.264/AVC FRExt. This work has been synthesized using Rohm 0.18um library. The design can work on a frequency of 93MHz and throughput of 1.488Gpixel/s with a cost of 56440 gates.

In the present work, high-speed video images of the ground take-off flight of a live butterfly were captured and their dynamic motions during the first full-stroke were analyzed. To capture the dynamic images of the take-off motion, the experimental setup consisted of a high-speed camera, a Xenon lamp as a light source and a transparent chamber of $15^W{\times}15^L{\times}17^H$ $cm^3$ in physical size. The ambient temperature and supplementary lighting devices were precisely controlled. The weight and wing span of the butterfly tested in this study was 104 mg and 63.14 mm, respectively. The ground take-off images were captured with 4000 fps with a spatial resolution of (1024${\times}$512) pixels. The period of the first full-stroke was 80.5ms and the flapping speed of downstroke was 2 times faster than that of upstroke. As a result, butterflies used the fling and near-clap motion to generate lifting force and an interesting take-off behavior of early pronation and downstroke was observed.

In this study, we investigated the spatial range, distribution pattern, temporal appearance, sex ratio, seasonal pattern, and size of the population of Leptalina unicolor locally inhabiting the wetland protection area in the Jaeyaksan Mountain. We found that the butterfly was distributed across four areas at 750 m above sea level and in an area of 96,000 ㎡. in the southeastern slope of the mountain. The discontinuous distribution of the butterflies in the meadow. According to our survey conducted from 2012 to 2014, L. unicolor occurred in May (spring) and July (summer) each year, with the male population more than three times higher than that of the female population. The population size estimated using the mark and recapture method on the back of the hind wing in the two years was as follows: 877±502 and 1243±800 individuals in the spring and summer of 2012, respectively, and 783±429 and 506±365 individuals in the spring and summer of 2014, respectively, suggesting no specific seasonal pattern. The findings of this study are expected to be useful for the conservation of the populations and habitats of L. unicolor, which are currently distributed locally due to a decrease in population size.
