Statement of problem: The clinical criteria of soft lining materials are resilience over an extended period, capability of forming a strong bond with denture base materials, dimensional stability, adequate tear strength, and color stability. Many researches and reports dealt with food colorants or denture cleanser, but not with fermented foods. Purpose : This study was designed to assess what fermented foods, such as soy sauce and red pepper paste that many Koreans have eaten, influence on the color stability of soft denture liners. Material and methods: The color differences (${\Delta}E^*$) were measured by spectrophotometer with different immersion time. For the procedure, thirty disk-shape specimens per 4 soft denture linears(Molloplast-$B^{(R)}$, Ufi Gel $SC^{(R)}$, Dura $Base^{(R)}$, Sofreliner $MS^{(R)}$) were fabricated with a thickness of 2mm and 16mm in diameter. Each 10 specimen were immersed into the beakers of fermented foods distilled water, and $L^*$, $a^*$, $b^*$ values were measured for the color difference(${\Delta}E^*$), on the 1st, 7th, and 28th day with spectrophotometer. Result and conclusion : 1. There were significant differences between samples(soy sauces, red pepper pastes, and distilled water) in Sofreliner $MS^{(R)}$ of 1st day after immersion(p<0.05). There were significant differences between samples in Sofieliner $MS^{(R)}$ and Ufi Gel $SC^{(R)}$ of 7th days after immersion(p<0.05). There were significant differences between samples in Molloplast-$B^{(R)}$ of 28th day after immers ion(p<0.05). 2. In red pepper pastes, ${\Delta}E^*$ values of Molloplast-$B^{(R)}$, Ufi Gel $SC^{(R)}$, Sofrelinev $MS^{(R)}$ weve higher than 3.3. Those values were not clinically acceptable. In soy sauces, ${\Delta}E^*$ values of all denture liners were lower than 3.3. ${\Delta}E^*$values of Ufi Gel $SC^{(R)}$ were higher than those of other denture liners 3. Based on the above results , red pepper paste causes more discoloration than soy sauce.

Objective : This study is to propose a new hypothesis about the interpretation of Jueyinbing in Shanghanlun by studying 2 Jueyinbing cases. Methods : We analyzed the original form of the chinese characters 'Jue(厥)', 'Jueyin(厥陰)' and 'Huoluan(?亂)' and tried to understand their contexts in Shanghanlun. At the same time, we analyzed 2 clinical cases diagnosed and treated as Jueyinbing according to newly hypothesized definition. Results : Both patients suffered from eye diseases which caused by concentrating on a sophisticated work by straining their hands, feet and chest during the night time. After the herbal intervention, their eye diseases are improved firstly. The National Eye Institute 25-item Visual Function Questionnaire (NEI-VFQ) score increased on both patients. Not only all the patients' chief complaints relieved but their other clinical problems such as limb pain, hand tremble also improved. Conclusions : These results highly insist that, at least in 15 characters provision of Shanghanlun, Jueyinbing had had the different usage from the conventional terminology, and it is assumed that Jueyinbing means the disease made by concentrating on a sophisticated work by straining hands, feet and chest during night time.

키워드 네트워크 분석 방법을 활용한 블록체인 트렌드 분석에 관한 연구

조성환(Seong-Hwan Cho) 한국정보전자통신기술학회 2018 한국정보전자통신기술학회논문지 Vol.11 No.5

본 연구는 키워드 네트워크 분석에 사용되는 텍스트마이닝과 의미연결망 분석 방법을 활용하여 블록체인의 산업 활용 분야로 언론 및 정부 발표에서 언급되고 있는 ‘금융’, ‘에너지’, ‘물류’를 언급한 기사들을 비교 분석하였다. 블록체인 적용이 언급된 산업 분야별로 기사의 내용 및 키워드의 차이를 파악하고 비교 분석하는 것을 목적으로 하였다. 2017년 1월부터 2018년 7월까지 언론에서 보도한 총 43,093건의 기사를 Python BeautifulSoup을 이용하여 네이버 뉴스에서 수집하였고, 세 용어의 상호 중복을 제거하기 위한 정제 작업을 수행하였다. 이후 키워드 간 네트워크 분석을 위해 텍스톰(Textom)과 UCINET을 이용하여 세 용어에 대한 텍스트마이닝과 의미연결망 분석을 진행하였다. 분석 결과, 세 용어는 모두 ‘기술’ 측면에서는 유사한 단어들이 있었으나, ‘정부 정책’이나 ‘산업’측면의 이슈 등에서 내용적 차이가 있었다. 또한 빈도 및 중심성에 있어서도 차이가 있음을 확인할 수 있었다. This study aims to identify and compare contents and keywords used in articles related to blockchain applications to various industries. The text mining and Semantic Network Analysis, as methods of keyword network analysis, were used to analyze articles including terms of ‘finance’ ‘energy’ and ‘logistics’, which media and government frequently mentioned as areas that can apply blockchain technologies. For this study, data were collected from 43,093 articles from January, 2017 through July, 2018. Data crawling was carried out by using Python BeautifulSoup and data cleaning was performed in order to eliminate mutual redundancies of the three terms. After that, text mining and semantic network analysis were performed using Textom and UCInet for network analysis between keywords. The results showed that all the three terms were similar in terms of "technology", but there were differences in the contents of "government policy" or "industry" issues. In addition, there were differences in frequencies and centralities of these terms.

윤곽선 맵과 다중 면 사이드 매치 유한상태 벡터 양자화를 이용한 영상 압축

조성환(Cho, Seong-Hwan),김응성(Kim, Eung-Sung) 한국산학기술학회 2007 한국산학기술학회논문지 Vol.8 No.6

본 논문에서는 영상의 윤곽선을 검출하여 배경 블록과 윤곽선 블록으로 분류하고 윤곽선 맵을 작성하여, 윤곽선 블록에 대해서는 다시 DCT의 AC 계수를 사용하여 16개로 세분화한 후, 다중 면 사이드 매치 유한상태 벡터 양자화를 수행하는 알고리듬을 제안한다. 윤곽선 맵의 정보에 따라 각각 주 부호책으로부터 상태 부호책을 작성하며, 현재 블록의 2면 또는 3면에 대해 사이드 매치 계산을 수행한다. 전송 비트 수를 줄이기 위해 먼저 부호화되는 블록들 중 배경 블록에 한하여 주 부호책으로 부호화 할 것인지를 결정한다. 또한 복호화기로 전송하는 부호단어 인덱스의 할당 비트를 줄이기 위해서 가변 길이 부호화를 수행한다. Zelda, Lenna, Bridge, Peppers 영상에 대하여 본 알고리듬으로 영상을 부호화 했을 때 SMVQ와 TSMVQ 알고리듬보다 더 좋은 영상의 화질을 얻을 수 있었다. In this paper, we propose an algorithm which implements a multi-sided side match finite-state vector quantization(MSMVQ). After extracting the edge information from an image and classifying the image into edge blocks or non-edge blocks, we construct an edge map. We subdivide edge blocks into sixteen classes using discrete cosine transform(DCT) AC coefficients. Based on edge map information, a state codebook is made from the master codebook, and side match calculation is done for two-sided or three-sided current block of image. For reducing transmitted bits, a decision is made whether or not to encode the non-edge blocks among the pre-coded blocks by using the master codebook. Also for reducing allocation bits of codeword indices to decoder, a variable length coder is used. Considering the comparison with side match finite-state vector quantization(SMVQ) and two-sided SMVQ(TSMVQ) algorithm about Zelda, Lenna, Bridge and Peppers image, the new algorithm shows better picture quality than SMVQ and TSMVQ respectively.

인공지능 : DCT 맵과 이진 트리 구조 벡터 양자화기를 이용한 영상 부호화

조성환(Cho Seong Hwan),김응성(Kim Eung Sung) 한국정보처리학회 1994 정보처리학회논문지 Vol.1 No.1

벡터 양자화기를 이용하여 영상의 부호화기를 설계하는데 있어서 2차원 이산여현변환(2D-Discrete Cosine Transform)에 근거한 DCT맵(map)과 새로운 부호책(codebook) 설계 알고리즘을 제안한다. 영상을 작은 부블록으로 나누고 2차원 이산여현변환으로 대부분의 정보를 포함하는 부분, 즉 부호화하기 어려운 부분과 부호화하기 쉬한 적은 정보를 포함하는 영역으로 나누어 맵을 만들고 이 맵에 따라 영상의 중요한 특징들을 2차원 이산여현변환으로 추출한다. 부호책은 트리 구조에 근거한 2진 트리로 두 영역을 따로 학습세트로 나눔으로서 만들어 진다. 2진 트리의 중산 노드에서 각 학습 벡터는 그 노드에서의 문턱 값과 비교하여 두개의 아래 노드중 하나에 속하게 된다. 국제 표준 화상인 Lenna와 Boat 영상에 대하여 본 알고리즘으로 영상을 부호화했을 때 PNN과 CVQ 알고리즘에 비하여 수행시간을 줄이고 PNN 알고리즘보다는 각각 약 0.45dB과 0.33dB 만큼, CVQ 알고리즘보다 각각 약 0.05dB과 0.1dB만큼 더 좋은 영상의 화질을 얻을 수 있었다. A DCT map and new codebook design algorithm based on a two-dimension discrete cosine transform (2D-DCT) is presented for coder of image using vector quantizer. We divide the image into smaller subblocks, then using 2D DCT, separate it into blocks which are hard to code but it bears most of the visual information and easy to code but little visual information, and DCT map is made. According to this map, the significant features of training image are extracted by using the 2D DCT. A codebook is generated by partitioning the training set into a binary tree based on tree-structure. Each training vector at a nonterminal node of the binary tree is directed to one of the two descendants by comparing a single feature associated with that node to a threshold. Compared with the pairwise nearest neighbor (PNN) and classified VQ (CVQ) algorithm, about ''Lenna'' and ''Boat'' image, the new algorithm results in a reduction in computation time and shows better picture quality with 0.45dB and 0.33dB differences as to PNN, 0.05dB and 0.1dB differences as to CVQ respectively.
