  • Objectives: The purpose of this study is to investigate the relationship between vasomotor symptoms with upper-lower body temperature differences, and to identify Kidney Deficiency pattern (腎虛證) in menopausal women. Methods: 51 women who visited Kangnam Kyung-Hee Oriental Hospital from July to December, 2013 were analyzed. The experimental group consisted of 30 patients reported with vasomotor symptoms (Vasomotor symptom group, VG), while the control group consisted of 21 patients without vasomotor symptoms (Control group, CG). According to their chief complaints, VG was further divided into VHG (vasomotor-hot flash group) and VCG (vasomotor-cold hypersensitivity group). The temperature differences between upper and lower body part (CV17-CV4), proximal and distal extremity part (LU4-HT8, ST32-LR3) were checked. All patients reported other complaints such as headache, sweating, anxiety, dyspepsia, leukorrhea, which belong to Kidney Yang Deficiency pattern (腎陽虛證) or Kidney Yin Deficiency pattern (腎陰虛證). The relationship between vasomotor symptom and repetition rate of additional complaints were analyzed. Results: Statistical analysis showed that lower abdomen temperature of experimental group was lower than the control group. Temperature differences of upper and lower body (CV17-CV4) was significantly larger in vasomotor symptom group. VHG had more symptoms of sweating, chest discomfort, constipation, which belong to Kidney Yang Deficiency pattern group. VCG had more symptoms of leukorrhea, diarrhea, and dyspepsia, which belong to Kidney Yin Deficiency pattern group. Conclusions: Climacteric women who suffered from vasomotor symptoms showed lower temperature tendency in [CV4], larger temperature differences in [CV17-CV4] compared to the control group. Among them, VHG showed more symptoms of Kidney Yin Deficiency pattern, whereas VCG showed more symptoms of Kidney Yang Deficiency pattern.

  • 발달중인 Sedum 및 Salsola의 엽육조직을 chemical fixation과 high pressure freezing (HPF) 등으로 고정한 후, 초박 및 후박절편으로 제작 carbon coating하여 TEM 및 UHVEM으로 연속절편에 의한 2-D영상과 tilt image data를 수집하였다. 이후 초미세 구조들에 대하여 tilting 및 tomography 기법, 그리고 디지털화한 image의 3-D 입체구조 재구현에 필수적인 IMOD 프로_그램을 적용한 image 처리과정을 거쳐 UHVEM data에서 색소체내 초미세구조의 정보를 추출하여 세포수준에서의 3-D image를 분석하였다. 색소체 기질에서 녹말입자 및 틸라코이드에 인접하여 형성되는 CAM및 $C_4$ 식물 색소체 결정체들은 어떤 막으로도 둘러싸이지 않는 구조로서, Sedum rotundifolium 색소체내 결정체는 수 ${\mu}m$에 이르는 커다란 크기로 형성된다. 결정체 내에는 약 20nm격자거리로 이루어진 기원을 알 수 없는 수백-수천 개의 미세소관성 요소들이 평행 또는 격자상태로 정교한 구조를 이루며, 티라코이드 및 녹말입자와 인접하여 발달하였다. $C_4$ 광합성 수행 Salsola komarovii의 경우, 결정체는 엽육세포 색소체에서만 발달하며 결정체 구성 기본요소들이 비교적 규칙적인 격자거리를 이루며 수십 개 배열하는 구조를 형성하였다. 특히, tilted image및 3-D 입체구조 연구에서 결정체 형성에는 이들과 인접하여 발달하는 틸라코이드막이 관여함을 알아 낼 수 있었다. 이는 엽육세포 색소체에는 결정체들이 식물이 수행하는 광합성 유형에 따라 각기 다른 구성요소로 형성되어 Sedum의 경우와 같이 발달 중인 엽육조직에서 분화하거나 Salsola에서와 같이 세포 유형에 따라 상이하게 발달하는 것으로 추정되었다.

  • The main objective of this research was to understand the latest trends of natural print design through the quantitative & qualitative analysis of fashion appeared in contemporary female collections. The research criteria was defined as 3 seasons from 2011 S/S to 2012 S/S. Data collection of 726 was done through review of 'pr$\hat{e}$t-$\grave{a}$-porter Collections' of three major fashion cities; Paris, Milan and NY. Statistical analysis of frequency with chi-square test was conducted. Also qualitative interpretation of natural print design' characteristics was completed. The main findings were as follows.; The average occurrence rate of natural print design from 2011SS to 2012 SS in three collections were 6.4% in Milan 6.4%, 5.5% in Paris and 6.8% in N.Y. The five source types of natural prints in contemporary women's fashion collections were identified and the order of their appearance were as follows: flowers, plants, animals, insects & marine organisms and compound one. The plant prints were expressed by stylized or realistic touch. Flower patterns showed more variables than plants, however, there were no big difference in their image and major characteristics. The animal prints demonstrated two aspects. First one used typical animal print of fur or skin, but the other one draw the animal figure like paintings. The compound source type presented the most interesting and fresh pattern design ideas. In the insects & marine organisms, mainly butterfly and seashell & starfish, etc. appeared as real shapes or sometimes were stylized.

  • This study analyzed the style, dimensions, fabric patterns, colors, and fabrics of a traditional Chinese women's dress from the Zhou Dynasty, and reconstructed it in the form of a virtual garment using 3D CLO. Based on ancient flat image data and three-dimensional portrait data, who wore them, how they were worn, and how they were coordinated was analyzed. In order to analyze the size and pattern of the straight Ju Chines dress, data from the excavation report and the tomb owner's anthropometric measurements were combined to infer the wearing condition and organize the sculptural features. Dimensional analysis was carried out using a well-preserved small-scale woven cotton cloth as a restoration model, and the horizontal and vertical dimensions were reasonably estimated using the shape proportioning method. The analysis of the colors and patterns of the fabrics was based on the colors and patterns of the fabrics excavated from Masan Tomb No. 1 during the Eastern Zhou, Qin, and Han periods. Finally, a virtual model was created using data from the excavation report and the age and height information of the owner of the excavated robe, and the pose and size of the virtual model were determined using 3D CLO. Based on the previous research data, the garment was virtually sewn and simulated. The shape, pressure, and strain of the garment in different postures was also compared. Through the research direction of pattern and 3D restoration, this research maximizes the restoration of Chinese traditional women's dress and presents it in a more intuitive, comprehensive, and vivid way.

  • Purpose: The aim of this study is to analyze the series of panoramic radiograph of implant patients using the system to measure peri-implant crestal bone loss according to the elapsed time from fixture installation time to more than three years. Methods: Choose 10 patients having 45 implant fixtures installed, which have series of panoramic radiograph in the period to be analyzed by the system. Then, calculated the crestal bone depth and statistics and selected the implant in concerned by clicking the implant of image shown on the monitor by the implemented pattern recognition system. Then, the system recognized the x, y coordination of the implant and peri-implant alveolar crest, and calculated the distance between the approximated line of implant fixture and alveolar crest. By applying pattern recognition to periodic panoramic radiographs, we attained the results and made a comparison with the results of preceded articles concerning peri-implant marginal bone loss. Analyzing peri-implant crestal bone loss in a regression analysis periodic filmed panoramic radiograph, logarithmic approximation had highest $R^2$ value, and the equation is as shown below. $y=0.245Logx{\pm}0.42$, $R^2=0.53$, unit: month (x), mm (y) Results: Panoramic radiograph is a more wide-scoped view compared with the periapical radiograph in the same resolution. Therefore, there was not enough information in the radiograph in local area. Anterior portion of many radiographs was out of the focal trough and blurred precluding the accurate recognition by the system, and many implants were overlapped with the adjacent structures, in which the alveolar crest was impossible to find. Conclusion: Considering the earlier objective and error, we expect better results from an analysis of periapical radiograph than panoramic radiograph. Implementing additional function, we expect high extensibility of pattern recognition system as a diagnostic tool to evaluate implant-bone integration, calculate length from fixture to inferior alveolar nerve, and from fixture to base of the maxillary sinus.

  • K-means clustering has been widely used in many applications, such that pattern analysis or recognition, data analysis, image processing, market research and so on. It can identify dense and sparse regions among data attributes or object attributes. But k-means algorithm requires many hours to get k clusters that we want, because it is more primitive, explorative. In this paper we propose a new method of k-means clustering using the grid-based sample. It is more fast than any traditional clustering method and maintains its accuracy.

  • The authors report three microcystic meningiomas with its characteristic immunohistochemical findings and chromosomal pattern. Three patients with surgically treated microcystic meningioma were studied for its radiological, histopathological findings, and chromosomal analysis was done in the one patient. Tumors were convexity meningioma in the frontal area. The tumors were enhanced homogenously in the two, and enhanced in homogenously with multiple small cysts in the other one on preoperative magenetic resonance image. Pathological examination showed marked nuclear pleomorphism, many small cysts, hyaline thickening in blood vessel wall, and mucinous background, compatable to microcystic type. EMA and vimentin were positive on the immunohistochemical stain. Chromosomal analysis showed tetrasomies of chromosome 5, 13, 17, and 20, and trisomies of chromosome 6, 7, 9, 11, 12, 16, 19, and 21, which are quite different from those of benign meningioma.
