  • Phytoliths formed on the leaf-blades of the seventeen Oryza species were examined using back-scattered electron imaging. The resulting descriptions of the phytoliths became the basis for a new key to the species of the genus. This key includes features useful for specific identification related to the silica bodies originating from epidermal cells upon both the mid-vein and bulliform cell, as well as of phytoliths originating from papillae, prickle hairs, large and small trichomes, and stomatal apparatus. These detailed phytolith descriptions, back-scattered electron images, and keys to both adaxial and abaxial sides of leaves, can now be used in identifying phytoliths from archaeological samples as well as extant species of Oryza.

  • This study of vascular plants was conducted over a period of 33 days from March to October of 2018 in Byeonsanbando National Park, South Korea. Based on voucher specimens and photographs, 829 taxa in total were recorded, including 141 families, 458 genera, 748 species, 16 subspecies, 59 varieties, and 6 forma. Two endangered taxa were identified, Iris koreana Nakai and Saururus chinensis (Lour.) Baill. Five rare taxa were found, including Abeliophyllum distichum Nakai and Hypodematium glanduloso-pilosum (Tagawa) Ohwi. A total of 17 Korean endemic plants were investigated. Examples include Elsholtzia byeonsanensis M. Kim, Eranthis byunsanensis B. Y. Sun, and Lycoris flavescens M. Kim & S. T. Lee. Of floristic regional indicators (third to fifth degree), 52 taxa were identified. Naturalized plants were identified, which included 79 taxa, and 7 species of ecosystem disturbance plants, such as Ambrosia artemisiifolia L., Lactuca serriola L., and Solidago altissima L. were found. We recorded 39 taxa of the plants vulnerable to climate change.

  • 최근 들어 3D에 관한 관심이 높아지면서 각종 기술적인 이슈는 물론 3D 콘텐츠의 제작 방향에 대한 논의가 활발하게 이루어지고 있다. 흔히들 3D 콘텐츠라고 부르는 것은 현재로선 어떤 특정한 장르나 엄정한 정의를 가진 용어라기보다는 일종의 새로운 매체기술을 위한, 매체 기준적인 콘텐츠의 분류 형태라고 볼 수 있을 것이다. 따라서 3D 콘텐츠라는 용어를 새로이 썼다고 해서 좋은 콘텐츠가 지녀야 할 근본적인 요소가 달라지는 것은 아니다. 물론 매체의 발전과 변화에 따라 대중들의 가치관, 예술적 시대적 패러다임, 근본적인 인간의 생활방식까지 바뀔 수 있다는 것은 자명한 사실이다. 이는 회화 문화에서 사진의 등장으로, 사진에서 동영상으로, 영화에서 TV와 비디오로, 그리고 아날로그에서 디지털로의 중심 이동이 인간의 삶에 얼마나 큰 변화를 초래했는지만 상기해봐도 쉽게 알 수 있다. 그러므로 3D기술이 가진 파급효과와 영향력이 어디까지인지 쉽게 단정할 수는 없는 것이다. 그러나 언급했듯이 어떤 콘텐츠라도 결국엔 인간이 향유하리란 점은 분명한 사실이다. 현재는 3D 콘텐츠의 제작 방향에 대해서 지나치게 매체 중심적으로 접근하려는 경향이 있는데, 역사적으로 언제나 인간에게 매력적이었던 콘텐츠의 기본은 변함이 없었다. 변하는 것은 오히려 매체나 기술, 하드웨어 쪽이었다. 따라서 콘텐츠를 매체에 이식하는 가변적인 내용물쯤으로 이해하는 기술중심의 사고에서, 인간이 근본적으로 원하는 이야기 콘텐츠를 구현하기 위해 매체가 변해왔다는 점을 이해해야 하는 콘텐츠 중심 사고도 할 필요가 있는 것이다. 본고에서는 과거 많은 매체들의 역사를 통해 새로운 매체 기반에서의 콘텐츠의 모습이 어떻게 변해왔는지를 되짚어 보려고 하며, 이를 통해 앞으로 3D 콘텐츠의 향방을 유추해 볼 기회를 마련하고자 한다.

  • Although three-dimensional measurement systems for the human body have been studied, there is still an error between the measurements by the two-dimensional measurement method and the three-dimensional scanning method. Especially, in the case of the breast, the outline is not clear. The breast is made up of subcutaneous fat and mammary gland tissue, and it is easy to deform, making it difficult to grasp the exact shape. It is also more difficult to measure photogrammetry or three-dimensional measurement because it is difficult to obtain subjects because of the shame they are reluctant to expose. In this study, the angle and length of the line connecting the measurement points of the breast detail measurement items were compared with the unchanged measurement items such as breast width and center front length using the frontal and lateral photographs taken before and after breast enlargement surgery. The results of the study are as follows. The types of breast before and after surgery were classified into two groups and showed high accuracy rate. Therefore, it was possible to classify the breast type using the frontal and lateral views of the breast, and it was found that The PRM method can distinguish the characteristics of the breast type. Therefore, it can be useful for classifying and discriminating breast types.

  • Recently, photo sharing and publishing based Social Network Sites(SNSs) are increasingly attracting the attention of academic and industry researches. Millions of users have integrated these sites into their daily practices to communicate with online people. In this paper, we propose an efficient face annotation and retrieval system under SNS. Since the system needs to deal with a huge database which consists of an increasing users and images, both effectiveness and efficiency are required, In order to deal with this problem, we propose a face annotation classifier which adopts an online learning and social decomposition approach. The proposed method is shown to have comparable accuracy and better efficiency than that of the widely used Support Vector Machine. Consequently, the proposed framework can reduce the user's tedious efforts to annotate face images and provides a fast response to millions of users.

  • This paper reports new hosts for three ichneumonids (Apophua evanescens evanescens, Teleutaea minamikawai, and Trathala flavoorbitalis) from South Korea. These three species were discovered from the lepidopteran pupae, viz., Cleora leucophaea (Butler) (Geometridae), Adoxophyes honmai Yasuda (Tortricidae), and Pyrausta phoenicealis (Hübner) (Crambidae), respectively. Among these, the lepidopteran family Geometridae and Crambidae are also newly recorded as host groups for the genera Apophua and Trathala.

  • The genus Brachydeutera Loew, 1862 comprises a small group of Acalyptratae flies belonging to the subfamily Ephydrinae of the family Ephydridae. So far, 16 described species have been recorded worldwide, and although the genus occurs in all fauna regions, it is most diverse in the subtropics and tropics, particularly in Africa and Asia. This genus has been recorded for the first time in the Korean fauna based on the discovery of a nominated species, B. meridionalis (Rondani, 1856). This paper provides the diagnosis, the morphological features, and an ecological photograph of the first recorded species.

  • 우리나라의 토양조사는 미농무성(USDA)의 분류방법에 따라 개략토양조사($'65{\sim}'67$년), 정밀토양조사($'68{\sim}'79$년), 논토양배양사업 10개년계획($'80{\sim}'90$년), 그리고 밭토양세부정밀토양조사($'95{\sim}'99$년) 등을 실시하였다. 현지에서의 토양조사는 지형, 배수등급, 토성, 자갈함량, 유효토심, 경사 등 현지의 지형지물 및 환경을 통하여 많은 정보를 얻을 수 있으며, 이를 통하여 전국에 대한 토양조사 결과, 토양통 (심토의 특성이 유사한 토양) 390개, 토양구(표토의 토성을 세분) 536개, 토양상(경사도 및 침식등급을 세분) 1,321개로 분류되어 있다. 우리나라 토양형성 발달에 미친 기후인자는 습윤권역(Udic moisture regime)과 토양온도는 mesic과 일부 남해안과 제주지역의 thermic인 토양온도(Soil moisture regime)였으며, 식생인자는 높은 지역의 경우에는 산림이 낮은 저지대 평탄지는 자연초지가 대부분이다. 지형인자는 동고서저지형으로 동부는 산악지, 서부는 경사가 완만한 구릉지며, 한강 등 대부분이 서남방향으로 흐르는 지형이다. 모재는 다양하나 70%이상이 화강암, 화강편마암이 주를 이루고 있었다. 시간인자의 경우에는 기간이 매우 오래되었으나, 지형이 복잡하여 토양발달이 약한 Inceptisol과 층위발달이 없는 Entisol이 대부분이며, 다음으로 Ultisol과 Alfisol이 뒤를 이었다. 일부 Andisol, Mollisol, Histosol이 존재하였다. 우리나라의 토양분류는 Soil Taxonomy에 의해 분류되었는데, 이것은 토양의 단면내에 존재하는 감식층위(Diagnostic Horizon)의 유무 및 종류에 따른 분류이다. 토양분류 결과 최고 상위분류 단위인 목(order)이 7개, 아목(suborder) 14개, 대군(great group) 27개, 아군(sub group) 67개, 속(family) 161개로 분류되었으며, 가장 저차단위인 통(series)이 390개 분류되었다. 또한 작물이용측면에서 실용적 분류를 실시하였는데, 논토양의 경우 보통논, 미숙논, 사질논, 습논, 염해논, 특이산성논으로 분류할 경우 각각의 분포면적이 31.9%, 23.0%, 31.9%, 9.1%, 3.9%, 0.2%이었다. 밭토양의 경우에도 보통밭, 사질밭, 미숙밭, 중점밭, 고원밭, 화산회밭으로 6개 유형으로 분류할 경우 각각의 분포면적은 41.9%, 23.3%, 17.5%, 13.9%, 1.1. 2.2% 이었다. 도시화 및 도로확대 등 다양한 토지이용 및 지형개변으로 과거의 토양정보가 많이 변경되었다. 그래서, 앞으로는 인공위성자료 및 항공사진을 이용하여 빠르고 쉽게 활용할 수 있는 토양조사 방법개발과 기 구축된 토양도의 수정, 보완 작업이 필요한 절실히 요구되고 있는 현실이다.

  • In this paper, we describe the development of a system for generating a 3-dimensional human face using 3D scanned facial data and photo images, and morphing animation. The system comprises a facial feature input tool, a 3-dimensional texture mapping interface, and a 3-dimensional facial morphing interface. The facial feature input tool supports texture mapping and morphing animation - facial morphing areas between two facial models are defined by inputting facial feature points interactively. The texture mapping is done first by means of three photo images - a front and two side images - of a face model. The morphing interface allows for the generation of a morphing animation between corresponding areas of two facial models after texture mapping. This system allows users to interactively generate morphing animations between two facial models, without programming, using 3D scanned facial data and photo images.
