  • 손톱 하부 모세혈관(Nailfold Capillary)의 형태와 분포 특징으로부터 다양한 질병을 밝혀내려는 시도가 꾸준히 있어 왔다. 손톱 하부 모세혈관은 그의 대표적인 형태 특징을 따라 몇 가지로 분류할 수 있고, 이 분포와 질병과의 상관관계가 밝혀진 종래 연구들도 다수 존재한다. 현재는 진단하는 과정을 의료 전문가가 직접 촬영된 모세혈관 사진을 보고 주관적인 평가를 하게 되는데, 이러한 분석 방법은 많은 시간과 휴먼 에러가 발생한다는 문제점이 있다. 이를 자동화하기 위하여 본 논문은 손톱 하부 모세혈관의 모세혈관들을 YOLO 객체 인식 모델을 활용하여 모세혈관을 탐지하고 모세혈관의 종류에 따라 분류하는 방법을 제안하고, 그 유효성을 검증하였다.

  • Multiview stereo (MVS) 3D reconstruction of a scene from images is a fundamental computer vision problem that has been thoroughly researched in recent times. Traditionally, MVS approaches create dense correspondences by constructing regularizations and hand-crafted similarity metrics. Although these techniques have achieved excellent results in the best Lambertian conditions, traditional MVS algorithms still contain a lot of artifacts. Therefore, in this study, we suggest using a transformer network to accelerate the MVS reconstruction. The network is based on a transformer model and can extract dense features with 3D consistency and global context, which are necessary to provide accurate matching for MVS.

  • 단 밴드 영상과는 달리 다차원 데이터는 분광적인 특성을 이용한 자동화된 영상 분석을 수행하는 장점이 있는 반면, 3차원 이상의 데이터를 분광차익 상에 시각화 하는데 어려움이 따른다. 클러스터링 기법을 이용한 영상 정보 추출은 자동화된 영상 분석적인 측면에서 중요한 분야 중 하나로서, 분광차원에서 구 형태의 조밀한 클러스터를 분리하는데 효과적인 방법으로 알려져 있지만 부정형(不定形)의 클러스터를 추출하는 방법에는 한계를 가진다. 따라서 본 연구는 모든 차원의 데이터를 2차원 상에 시각화하여 화소간 인접성을 개략적으로 확인할 수 있는 Star Coordinates 기법을 제안한다. 데이터의 다차원 시각화를 통해, 부정형 클러스터를 제거하여 다음 단계의 영상 분석 시 발생할 수 있는 오류를 방지할 수 있고, 명확한 클러스터를 확인 지정하여 클러스터링 정확도를 골일 수 있을 것으로 기대된다. 부가적인 연구고서, Star Coordinates 기법을 적용하여 Plot된 영상 데이터를 K-Means 알고리즘을 이용한 무감독 분류를 수행하여 그 결과를 확인하였다.

  • 지난 수십년간 부직포 산업에 대한 관심이 증대되고 있고, 정부차원에서 환경문제에 관심이 고조되면서 부직포를 이용한 FILTER의 수요는 꾸준히늘고 있다. 특히 대구의 페놀사건 및 리우회담 개최 등으로 환경문제에 전국민이 적극적으로 대응하고 관심의 영역이 급속히 넓어짐으로 인하여 공해방지용 각종 FILTER와 집진기용 FILTER의 수용가 상당히 증가되고 있는 실정이다. 또한 리우회담을 계기로 정부의 공해방지 및 환경에 대한 규제도 대폭 강화되었다. 이에 따라 기존의 직물을 소재로 한 여과매체보다 형태의 안정성, 다양성, FILTERING 효과에서 앞서고 있는 부직포의 여과매체에 대한 관심이 점차 높아지고 있는 실정이다. 따라서 아질 개발하지 못한 부직포를 이용한 FILTER의 개발이 시급하고, 미개척 분야에서의 부직포 사용을 위한 연구가 꾸준히 이루어져야 하겠다. 그리고 환경규제가 강화됨에 따른 고서능 여과포의 개발 또한 시급한 실정이다. 본 장에서는 부직포를 이용한 여과매체, 즌 BAG FILTER의 제조 및 선정 등에 대하여 간략하게 소개하고 추후 부직포 산업의 활성화에 미약하나마 보탬이 되길 바란다.

  • As the popularity of single-person media content increases, We investigated the causal relationship between perceived value and intention to recommend to others. Individuality was studied on the tendency to sensation seeking and novelty seeking, which is a tendency to take boredom sensitive to monotonous and repetitive daily routines, and novelty seeking refers to new information and stimuli. The hypothesis was that high sensation seeking and high novelty seeking would perceived emotional value, epistemic value, and economic value for a single person 's media content. Hypothesis testing was performed using multiple regression analysis using SPSS21. As a result of the hypothesis test, The novelty seeking has a positive effect on emotional value, epistemic value, and economic value. Users who want to explore and enjoy new things could perceived the emotional value of having fun, fun, and sadness through single-person content, perceived a epistemic value and enjoy new information and situations as a tool to recognize new stimuli and know what they didn't know. And it could be seen that users perceive the economic value that they can enjoy at low cost or free service. The sensation seeking has a significant effect on epistemic value, but it did not affect emotional value and economic value significantly. Those who have a high tendency to sensation seeking can perceive curiosity about one-person media contents, so that they can perceive epistemic value. However, those who feel that they have not significant influence on economic value and emotional value can easily understand that expecting one's content does not feel bored by paying for a low cost or free service.

  • Purpose: Rice bran is a byproduct of the hulling of rice and contains a variety of bioactive components. Various studies have reported on the antioxidative, anticancer, immune-enhancing, and hypocholesterolemic effects of rice bran. However, few studies about the physiological activity of stabilized rice bran supplement on dietary intake of sugars is limited. The aim of this study was to investigate the effect of stabilized rice bran supplement on blood glucose in C57BL/6 mice fed a high sucrose diet. Methods: Animals were randomly divided into three groups respectively, and were fed a normal diet (ND group), a high sucrose diet (HSD group) or a high sucrose diet containing 20% stabilized rice bran (HSD-SRB group) for 12 weeks. Results: In the oral glucose tolerance test (OGTT), after seven weeks of feeding on the experimental diets, a significantly lower result was observed for HSD-SRB than for HSD at 30 and 60 minutes after oral administration in glucose solution (2 g/kg body weight). The incremental area under the curve (IAUC) of HSD-SRB was significantly lower than that of HSD. After 12 weeks, fasting blood glucose level of HSD-SRB was significantly lower than that of HSD. No significant difference in the serum insulin level was observed between HSD and HSD-SRB. However, HOMA-IR was significantly decreased in HSD-SRB compared to HSD. In addition, HOMA ${\beta}$-cell was significantly increased in HSD-SRB compared to HSD. Triglyceride in liver of HSD-SRB was significantly lower than that of HSD. Conclusion: Feeding diets containing 20% rice bran improved insulin resistance and insulin secretion by decreasing triglyceride in liver. Thus, rice bran has a positive effect on glycemic control. In addition, the results are expected to be utilized as a basis for human study and development of food products with added rice bran.

  • As an attempt to grasp the current situation of traditional Korean books scattered about in the world, this study has bibliographically analyzed first of all traditional Korean books as well as old Korean maps and atlases, and topography descriptions collected by L. C.. Traditional Korean books have been analyzed classified by subject, printing or manuscript, and the kind of edition. Historical development in the compilation of geographical materials during the Chosun Dynasty has been studied. Especially on old Korean maps and atlases bibliographical characteristics have been researched. Accordingly. the foundation has been laid not only for the study on the bibliographical characteristics and the current situation of traditional Korean books and old Korean maps and atlases but also for the comparative analysis on traditional Korean books in Korea with the ones collected by L.C.

  • Fourteen species of the genus Gonocephalum and one species of the genus Opatrum (Tenebrionidae, Opatrini) from Korea have been previously recorded. They are taxonomically reviewed based on many faunistic reports and research papers. We also examined many specimens including voucher materials of the previous studies. Among the recorded species, G. sabulosum is excluded because it was misidentified for the individual variation of Opatrum subaratum. We couldn’t find any Korean materials of four species (G. japanum, G. bilinearum, G. outreyi, G. malayanum), and used the materials determined from other countries. Key to 13 species of the genus Gonocephalum, illustrations of adults and male aedeagus are provided.

  • KORMARC formats have been developed in accordance with type of materials at different times. The format was firstly developed and soon after with formats for serials, audiovisual materials, archival and manuscript materials. Although all of the formats were developed according to the same principles, there were same inconsistencies among them. However, there are solved above problems as integrating KORMARC bibliographic formats. First of all, the result was better than we had expected both unified cataloging rules and standard of a descriptive form as accepted KCR4. This study is to roughly analyze integrating process, integrating contents, and problems of KORMARC format.
