The family Ptiliidae (Insecta: Coleoptera) has approximately 1,000 valid species in 100 recognized genera. Ptiliid beetles are readily collected from various habitats. They can be distinguished by feather-like hindwings and small body sizes. The genus Acrotrichis is the largest ptiliid genus. It contains almost a quarter of all ptiliids. In Korea, a single species of Acrotrichis lewisii (Matthews, 1884b) was recently reported in 2020. In this paper, we report two additional species, A. thoracica (Waltl, 1838) and A. grandicollis (Mannerheim, 1844) from the Korean Peninsula, collected during an assessment of biological variation in agricultural land of Jeju Island. Illustrations of habitus and diagnostic characters, distribution map and a key to Korean Acrotrichis species are provided.

The objective of this study was to investigate the cooking properties of seven different rice cultivars (Dasan, Keunseom, Goami, Baekjinju, Seolgaeng, Hangangchal, and Heukseol). For the Hunter's color values, the L value was highest in the Seolgaeng cultivar, the a value was highest in the Heukseol cultivar, and the b value was highest in the Hangangchal cultivar. For the water absorption rate, that of the Heukseol cultivar was 80 min up to the saturation point, those of the Dasan and Goami cultivars were 50 min, those of the Baekjinju and Keunseom cultivars were 30 min, and that of the Seolgaeng cultivar was 10 min. The water absorption was highest in the Keunseom cultivar (351.38%). The expansibility and soluble-solid contents were 226.97-551.08 and 5.56-21.05%, respectively. The hardness of the cooked rice was highest in the Heukseol cultivar (24.30 kg); conversely, the Hangangchal cultivar had the lowest value (7.49 kg). Goami was a hard cooked rice, except for the Heukseol cultivar. In the sensory evaluation of the cooked rice, the taste, texture, and overall preference were highest in the Baekjinju cultivar, the color was highest in the Seolgaeng cultivar, the flavor was highest in the Heukseol cultivar, and the appearance was highest in the Hangangchal cultivar. The Dasan and Keunseom cultivars yielded the lowest values in the sensory evaluation, except for texture.

본 논문은 실시간 옷감 애니메이션을 생성하기 위한 기법을 설명한다. 이 논문에서는 질량 스프링 모델에 기반한 물체를 가상현실 환경에서 실시간에 움직이기 위한 수치적분 기술을 다루고 있다. 많은 연구자들이 옷감과 같이 객체의 움직임과 외형을 표현하기 위한 다양한 기법들을 제안했지만. 옷감 객체를 가상 현실 환경에서 실시간으로 움직이게 하는 일은 여전히 어려운 문제이다. 옷감 애니메이션의 가장 큰 문제는 옷감의 움직임을 표현하는 운동 방정식을 수치 적분하는 것이 안정적으로 수행되지 않는다는 것이다. 1990년 Baraff의 논문에서 제시된 것과 같이 암시적 적분법이 이러한 안정성 문제를 해결해 주기는 하지만, 암시적 적분법은 수치적분 문제를 선형시스템 풀이 문제로 바꾸기 때문에 사실적인 외형을 가진 복잡한 모델의 애니메이션을 실시간 혹은 상호작용적으로 생성하는 문제에는 그대로 적용할 수가 없다［1］. 암시적 적분법의 이러한 문제점들을 해결하고 실시간 흑은 상호작용적 애니메이션을 얻기 위해 몇 가지 근사 기법들이 제안되었다. 하지만. 이러한 근사 기법들은 지나친 근사에 기초하고 있기 때문에 실제 옷감의 움직임과 같은 사실적인 동작을 생성하지 못하였다 이 논문에서 소개할 기법은 사실적인 옷감 주름을 생성할 수 있을 정도로 복잡한 옷감 모델을 다루면서도, 이전의 근사 기법들이 생성할 수 없었던 사실적인 움직임을 얻을 수 있다. 따라서, 본 논문의 기법은 가상 현실 환경에서 시스템 전제의 상호작용성을 해치지 않으면서도 매우 사실적인 옷감 모델을 포함할 수 있도록 해 준다. 제안된 기법은 수치적분의 안정성을 위해 암시적 적분법에 기반하고 있으면서도, 선형 시스템의 해를 효과적이면서도 사실성을 해치지 않도록 근사하여 실시간 옷감 애니메이션을 생성한다.한다.수행하였다. 분석에서는 제품의 효율성뿐만 아니라 보안성을 중요하게 생각하였으며, 앞으로 보안 관련 소프트웨어 개발에 사용될 수 있는 도구들이 가이드 라인에 대한 정보를 제공한다.용할 수 있는지 세부 설계를 제시한다.다.으로서 hemicellulose구조가 polyuronic acid의 형태인 것으로 사료된다. 추출획분의 구성단당은 여러 곡물연구의 보고와 유사하게 glucose, arabinose, xylose 함량이 대체로 높게 나타났다. 점미가 수가용성분에서 goucose대비 용출함량이 고르게 나타나는 경향을 보였고 흑미는 알칼리가용분에서 glucose가 상당량(0.68%) 포함되고 있음을 보여주었고 arabinose(0.68%), xylose(0.05%)도 다른 종류에 비해서 다량 함유한 것으로 나타났다. 흑미는 총식이섬유 함량이 높고 pectic substances, hemicellulose, uronic acid 함량이 높아서 콜레스테롤 저하 등의 효과가 기대되며 고섬유식품으로서 조리 특성 연구가 필요한 것으로 사료된다.리하였다. 얻어진 소견(所見)은 다음과 같았다. 1. 모년령(母年齡), 임신회수(姙娠回數), 임신기간(姙娠其間), 출산시체중등(出産時體重等)의 제요인(諸要因)은 주산기사망(周産基死亡)에 대(對)하여 통계적(統計的)으로 유의(有意)한 영향을 미치고 있어 $25{\sim}29$세(歲)의 연령군에서, 2번째 임신과 2번째의 출산에서 그리고 만삭의 임신 기간에, 출산시체중(出産時體重) $3.50{\sim}3.99kg$사이의 아이에서 그 주산기사망률(周産基死亡率)이 각각 가장 낮았다. 2. 사산(死産)과 초생아사망(初生兒死亡)을 구분(區分)하여 고려해 볼때 사산(死産)은 모성(母性)의 임신력(

The purpose of this study is to make theoretical examinations into the makeup trend shown in digital communication environment and thereby determine potential associations of makeup trend with digital communication environment and characterize said trend, so that it can provide reference materials required for follow-up studies. This study comes to the following findings: First, it is found that there are sociocultural characteristics of digital communication environment, such as interactivity, technology-orientedness, sentiment-orientedness and mixture of time and space. Secondly, it is found that trends developed in makeup fall categorically into interactivity, virtuality, amusement and mobility. Thirdly, it is found that each type of digital communication adopts a mixture and juxtaposition of contemporary styles or categories with traditional ones through eclectic combination based on open-minded and horizontal ideas. Fourthly, it is found that a trend from digital communication environment doesn't coincide perfectly with any makeup trend, but the former trend works interactively and organically with the latter trend on the basis of homogeneity and similarity within a general framework that represents external esthetics of human being. With the creation of digital communication environment, our contemporary society forms as the complex phenomena of digital society in a combination and destruction of different categories beyond any certain international boundary, so that a hybrid tendency appears in contemporary makeup trend as well. Based on these findings, this study has its implications in the sense that it gives a new viewpoint based on design, formative characteristics and expression styles of makeup, and also provides useful reference materials for related industrial sectors.

The mutual relationship between fashion and architecture and the similarities in their form and structure have been continuously debated over the decades, considering that both spheres are objects used in human life. Both spheres bring about the creation of three-dimensional space structures that are completed by the human body and material, based on a design targeted for people. The similarities between fashion and architecture in terms of form and structure have been debated by western architecture scholars focusing on the support that holds the garment's shape, the tailoring of a men's suit and also the material. The debate originates from the discussion of F. Th. Vischer, Kritische Gnge, and Gottfried Semper during the nineteenth century on the similarities between crinoline and the form of architecture and also the similarities between sewing and architecture. However, architects always regarded fashion as the inferior creative process that follows architecture in viewing the relationship between fashion and architecture. During the mid to end of the twentieth century, contrary to previous decades, the sense of fashion in architecture stood out, as an issue and a different approach was taken in discussing architecture that incorporates fashion. Accordingly, in the mid 1990's, architecture scholars such as Deborah Fausch and Mark Wigley began to conduct close observation of the mutual relationship between fashion and architecture from a more equal point of view. Notwithstanding, their point of view was still biased towards architectural standards. Commencing the Millennium, fashion has become the primary work of creation which leads style in all spheres, and under these circumstances this point of view has transferred from architecture to fashion when thinking about relationships between these spheres. The discussion on fashion and architecture form fashion's point of view is currently concentrated on the post 1990's phenomenon and illustrates the environment that is related to architecture. In general, the discussion is limited to determining a work of an individual designer as 'being architectural' when explaining the sculptural form of fashion. Therefore, this research aims to renew the discussion on twentieth century fashion design, which was neglected in any studies on observing architecture and fashion. The aim of this research is to classify the architectural paradigm of twentieth century fashion design and to observe the architectural forms of the respective eras. It is necessary to have a close observation of the architectural paradigm in twentieth century fashion design where support tools such as the crinoline was avoided and the form and functionality of the garment itself was emphasized. I will conduct this research by considering the architectural form shown in fashion as a practical three-dimensional creation that exists in space.

We investigated the physicochemical properties and starch structure of various rice varieties including 15 colored cultivars. NKHC showed the highest level of protein, lipid, and total dietary fiber levels. Reddish brown rice showed higher lipid content than that in black rice cultivars. Apparent amylose content of waxy and non-waxy colored rice varieties was within the range of 3~5% and 15~18%, respectively. IP exhibited the highest total starch (TS) content, whereas, NKHC and HJJ showed lower TS content than that in other cultivars. Pasting temperature of all colored rice cultivars, except IP, was about $68^{\circ}C$. Peak viscosity of IP, JJJ, Hong, and GGHM showed high values of 138, 130, 128, and 124, respectively. All the colored rice cultivars presented A-type X-ray diffraction pattern and polygonal shapes of starch granules were observed using scanning electron micrographs (SEM). Major groups of amylopectin chain lengths were B (12 < DP ${\leq}$ 24) and A (DP ${\leq}$ 12). SMHC showed the highest B chain content and the lowest A chain content (P < 0.05). These experimental results provided useful information for scientists and the food industry regarding colored rice starches.

The experiment was carried out to select the rice cultivar adaptable to Top Rice cultivation region from 2006 to 2007 in Useong and Kyeongju, Korea. Four cultivars, recommended for high rice grain quality, were cultivated in the different region in this study. The average yield of head rice was higher in Samguangbyeo than the other three cultivars. The protein content was inversely associated with palatability (Toyo value). The protein content of Samguangbyeo was 6.2%, which was the lowest among the tested cultivars. L values in color of rice and cooked rice were not significantly different. The hardness of Samguangbyeo was lower than that of the other cultivars in texture properties of boiled rice on 4 cultivars. In conclusion,considering the rice yield and grain qualities, Samguangbyeo was selected as promising rice cultivar for Top Rice cultivation region.

They are used as a symbol representing some meaning of an object. Geometric patterns in the formative arts have been recasted by artists and used to express modern images. Simple shapes of geometric patterns create beauty with their outward appearance and decorated patterns. The simpleness of decorated patterns go with restrained, rational, and modern concepts. The patterns decorated with geometric patterns use geometric figures such as octagon, triangle, quadrangle, etc. and they give satisfaction to modern people. They are also regular and simple, so they can create impactive visual effects and three-dimensional space can be created with these dynamic patterns. Therefore, attractiveness of shape which gives enjoyment is also found in tableware design using geometric patterns. Using geometric patterns in tableware design is not based on a chance factor, so it is possible to objectify and reproduce the patterns. These repetitive designs can influence a lot of designers working on tableware and help improve the tableware designs. It is also considered that those designs are able to create new opportunities to produce a high value product in the ceramics industry.
