During face recognition process, face detection process is most preceding process. However, face has very high floating property, so the result could be very different according to which method we used. This paper studies about eye detection and eye blinking verification using edge and color information from YCbCr distribution map, segmentation, and labeling methods.

BIM having started from architecture is being used in civil structure, but there are very few examples despite its effectiveness. In this paper, based on BIM technology, it is presented the method and result of developing web-based 5D system connecting cost, schedule and 3D model from the cable-stayed bridge. Through the system, the user can understand easily schedule on specific time and during some period and extract cost directly. This system also can manage various data types such as drawings, 3D models, documents and photos, for enhanced communication between stakeholders.

The aim of this study was to evaluate the monitoring efficiency of camera trapping in wild animals and to determine ways to increase its utilization. Nineteen sensor cameras were installed in Sobaeksan National Park from October 2012 to September 2013. During the study period, a total of 1045 terrestrial mammal photos were secured and 15 species habitats were identified. Shooting frequency was higher for medium and large mammals, especially full images of carnivores accounted for approximately 83%. A comparison of track surveys revealed that camera trapping was highly efficient and helped in capturing real image of species. The supply of lure and bait stimulates the sense of smell in carnivores, which further enhances the capturing of images by camera trapping. The results of this study provide data on the ecological characteristics of mammals, which can aid in determining habitat use by these animals, and thereby facilitate prevention of crop damage by wildlife.

10월 정기 답사 일정으로 아산 외암리 민속마을을 답사하고, 두 번째 일정으로 충남과학교육원을 답사했다. 아주 우연히, 바로 옆 '모나무르 카페 더 그린'이 괜찮은 카페라고 소개받아 추가로 답사를 했는데 건축물의 외관을 보았을 때는 별로 흥미를 느끼지 못했다. 그러나 반전이 있었다. 내부로 진입했을 때 건축물로 둘러싸인 내부에 중정으로 만들어진 워터가든에서는 놀라운 풍경이 그려지고 있었다. 중정에 설치된 워터가든을 에워싼 건축물은 카페, 예식홀 등 복합문화공간으로 구성돼 있어 관람객은 모두 워터가든과 곳곳에 설치된 조각, 예술품을 관람할 수 있으며, 자연 풍경도 같이 즐길 수 있었다. 많은 사람들이 즐기는 풍경을 보니 무척 재미있는 공간이라는 생각이 들었고, 이를 디자인한 건축사의 영감이 그렇게 부러울 수가 없었다. 우리는 주로 어떤 목적지를 선정해 답사를 하지만, 이처럼 예정에도 없었던 건축물과 풍경을 만나게 되면 답사의 즐거움이 배가 되는 기쁜 경험을 하게 되어 다시 다음 답사 일정이 기대된다.

Three species belonging to the genus Trapania Pruvot-Fol, 1931 are redescribed from Korea in this paper: Trapania euryeia Gosliner & Fahey, 2008, T. japonica (Baba, 1935), and T. toddi Rudman, 1987. Among these species, T. japonica is newly added to Korean fauna. The genus Trapania is characterized by a pair of extra-rhinophoral appendages on each side of the head, tentacular foot corners, a pair of extra-branchial appendages present around the gill, radula formula N×1.0.1. and consists of denticulated teeth, triaulic reproductive system, and minute spines on the armed penis. Herein, synonyms of the genus Trapania are summarized through a detailed literature review and the diagnostic characters of the genus Trapania are provided. Three species of the genus Trapania from Korea are distinguished from each other based on the color of extra-rhinoporal appendages and extra-branchial appendages, ground color, and distribution range of the brown markings on the dorsal surface. A taxonomic key to the genus Trapania in Korea is provided. In addition, the morphological characteristics of three trapanian nudibranchs in Korea are described and detailed photos of living animal are provided.

Nine species of Curculionidae, Pimelocerus elongates (Roelofs, 1873), Phylaitis maculiventris Voss, 1958, Egiona picta (Roelofs, 1875), Cryptorhynchus electus (Roelofs, 1875), Rhadinopus confinis Voss, 1958, R. sulcatostriatus (Roelofs, 1875), 1962, Deiradocranus setosus (Morimoto, 1962), Rhadinomerus annulipes (Roelofs, 1875), and R. maebarai Chujo et Voss, 1960 are recorded for the first time in Korea. And the distribution of the species of Shirahoshizo hiurai Morimoto to Korea which its distribution was unclear is confirmed with this report. Habitus photos and descriptions of the species are given.

Purpose: To evaluate clinical efficacy and safety of hyaluronic acid based autologous dermal fibroblasts (Hyalograft 3D) in the treatment of diabetic foot ulcers. Methods: A total of 28 patients with diabetic ulcers were randomized to either the control group with nonadherent foam dressings(n=14) or the treatment group with autologous tissue - engineered grafts(n=14). Weekly assessment contained vital sign checks, ulcer size measurements, and wound photos. At 12th week, percentages of complete wound healing and mean healing times were compared. Safety was also monitored by adverse events. Results: Complete wound healing was achieved in 84.6% of the treatment group and 23.1% of the control group (p<0.005). The mean times of closures for the treatment versus control groups were 6.1 weeks and 10.9 weeks, respectively. No adverse events related to the study treatment occurred. Conclusion: The use of hyaluronic acid based autologous fibroblast grafts was found to be a safe and effective treatment for diabetic foot ulcers.

The specimens collected from five localities during the period from 2004 to 2022 were observed. As a result of this study, Jellyella eburnea was found to be new to the Korean fauna and three membraniporids were reviewed. Two species, Jellyella eburnea and Biflustra grandicella, were redescribed and illustrated with the collected specimens in this study. Membranipora perfragilis from Korea is changed into Biflustra grandicella. Jellyella eburnea is new to the Korean fauna and first reported outside subtropical and tropical seas of the South Pacific and Indo-Pacific Ocean. This fact proves that the seas in Korea are warming. Additionally, Biflustra crenulata reported from the West Sea, South Sea and Jejudo waters of Korea is synonymized into Biflustra okadai. Membranipora irregulata is transferred into the genus Biflustra. Five of Korean membraniporids, Biflustra grandicella, Biflustra irregulata, Biflustra okadai, Jellyella eburnea, and Jellyella tuberculata, are reported in the Korean fauna as a result of this study. The photos taken in the field and by Scanning Electron Microscopy of two species, Biflustra grandicella and Jellyella eburnea, are provided herein.

Carex kamagariensis K. Okamoto was found in throughout the nation. This species is distinguished from other related taxa in Carex sect. Mitratae by pistillate scales with a long arista and achenes constricted above in the middle. A new Korean name, 'Jom-mok-po-sa-cho', is based on its small size and floral character similarity to C. genkaiensis. In this study, a description, illustrations and habitat photos of the species are provided. The key of its related species is also provided.

In a cultivated field of Salicornia europae in the Jeonam Province, Korea, Scrobipalpa salinella (Lepidoptera, Gelechiidae) which feeds and leads to a serious damage was found. The discovery of this species is to reconfirm its distribution in Korea because the first report by Park and Ponomarenko (2006) was based on a single female and it was collected in a montane area far from seaside where its host plants, halophytes, are planted. For identification, photos of imago and genitalia are given, and the damage by larvae on Salicornia europae are noted.
