Shoos-in in Nara of Japan has two kinds of Priest's robe(Kasa : 袈裟) ; one is Jiksung Kasa(織成袈裟), the other Janap Kasa(刺納袈裟). The former is listed as the 'Jiksung Kasa of tree bark color in seven stripes' in the Treasures Record(珍寶帳) of objects dedicated by Empress Komyo on the 21st day of the 6th month 756 A.D. The warp threads are brown and the weft threads are in groups of two in two colors-dark blue, green yellow and red. The latter is the so called Janap Kasa, of tree bark colors in seven stripes, that was also dedicated by Empress Komyo, 'Ja' means to stitch, and 'Nap' means to sew. It is made of patches of silk of various color, placed overlapping one another in patterns the resemble a mountainous landscape. All are stitched together in a continous quilt-like manner with purple threads. Japan has been under the strong influence of Korea Buddhism during the Nara period. Acording to Nihonki(日本書紀) and Sokunihonki(續日本紀), from 668 to 769 A.D., Japan has bought numorous objects including Buddhist utensils such as priest's robes and banners from Korea. Also during the same period Japan has perchased many kinds of dyestuffs and paint. So we can be certain that priest’s robes were imported from Korea like many other objects of Shoso-in.

한국산 칼납자루 Acheilognathus limbata(Temminck et Schlegel)의 분류학적 재 검토를 위하여 일본산과 한국산의 표본에 대한 난의 형태와 발생과정 및 외부 형태 형질을 비교 분석하였다. 한국산 표본은 난의 형태가 장타원형이고 난할시 동물극에서 세포 분열이 이루어지지만 일본산 표본의 난형은 둥근 타원형이고 난황의 측면에서 세포 분열이 이루어지고 있어 발생학적인 차이가 현저하다. 한편 17개의 계수 계측 형질의 비교에서 두장에 대한 문장의 비가 일본산은 한국산에 비하여 작고, 양안 간격의 비에 있어서도 일본산이 한국산에 비하여 현저하게 다른 점등으로 한국산 표본은 일본산 Acheilognathus limbata와 동종이라기 보다 분류학적을 구분되는 별종일 가능성이 있어 이에 대하여 논의 하였다.

Since Seoul was selected as the world design capital at the end of 2007, the endeavors to modernize the Korean unique beauty is becoming more tangible. Especially, the commercial spaces to be used by the general public and tourists have the value for study in the respect that such spaces for the national iconic images and have a large and far-reaching effect to transmit the national identity. Therefore, this study analyzed the design coordination properties in the Koreanity expression found in the modern commercial spaces. the foundation for the analysis was based on Leonard Koren's work on the arrrangement rhetoric theory, 'Arranging things(2003), and the contents of Korean expression were reviewed with professional jounals. the results are as follows: First, the design coordination properties in the Koreanity expression shown in modern commercial spaces are black-white contrast, natural materials, curved shapes, brevity, and simple beauty. Especially, some elements such as wood, traditional Korean papers, stones, mid-to-low chroma natural colors, checked patterns, and crazy patterns are used with overlapping and it is viewed that it is necessay to more aggressively seek for the disappeared traditional elements in the Korean modeling properties. Second, the concrete images of Korean expressions could be summarized as four adjective image groups, Natural, Subtitle, Gentle and Magnificent.

Purpose: The purpose of this study was to compare the dimension safety evaluation between a general ultrasonic cleaner and an ultrasonic cleaner equipped with UV-C (ultraviolet-C). Methods: An edentulous model was prepared. A denture base and an occlusal rim were fabricated, and scanning was performed. After scanning, a denture base and full arch artificial teeth were designed. The full arch artificial teeth were printed using a three-dimensional printer (n=10). The residual resin was washed with alcohol and then scanned (reference data). The printed specimens were classified and cleaned using a general ultrasonic cleaner (GU group) and an ultrasonic cleaner equipped with UV-C (UC group). After each washing, a rescan was performed (scan data). Reference data and scan data were superimposed using overlapping software. Data were statistically analyzed using the Mann-Whitney test (α=0.05). Results: In the deviation values of full arch artificial teeth, the GU group showed a high deviation of 18.02 ㎛ and the UC group showed a low deviation of 15.02 ㎛. The two groups demonstrated a statistically significant difference (p<0.05). Conclusion: Full arch artificial teeth prepared using photopolymerized resin were deformed according to the temperature of water generated in the ultrasonic cleaner. It is judged that there is no deformation according to the UV-C ultrasonic cleaner.

Objectives : This study aims to increase efficiency of the prescription similarity analysis method that uses drug composition ratio. Methods : The controlled experiment compared result generation time, generated data quantity, and accuracy of results between previous and new analysis method on the 12,598 formulas and 61 prescription groups. Results : The control group took 346 seconds on average and generated 768,478 results, while the test group took 24 seconds and generated 241,739 results. The test group adopted a selective calculation method that only used overlapping data between two formulas instead of analyzing all number of cases. It simplified the data processing process, reducing the quantity of data that is required to be processed, leading to better system speed, as fast as 14.47 times more than previous analysis method with equal results. Conclusions : Efficiency for similarity analysis could be improved by reducing data span and simplifying the calculation processes.

We propose a probabilistic fish growth model for smart aquaculture systems equipped with IoT sensors that monitor the ecological environment. As IoT sensors permeate into smart aquaculture systems, environmental data such as oxygen level and temperature are collected frequently and automatically. However, there still exists data on fish weight, tank allocation, and other factors that are collected less frequently and manually by human workers due to technological limitations. Unlike sensor data, human-collected data are hard to obtain and are prone to poor quality due to missing data and reading errors. In a situation where different types of data are mixed, it becomes challenging to develop an effective fish growth model. This study explores the unique characteristics of such a combined environmental and weight dataset. To address these characteristics, we develop a preprocessing method and a probabilistic fish growth model using mixed data sampling (MIDAS) and overlapping mixtures of Gaussian processes (OMGP). We modify the OMGP to be applicable to prediction by setting a proper prior distribution that utilizes the characteristic that the ratio of fish groups does not significantly change as they grow. We conduct a numerical study using the eel dataset collected from a real smart aquaculture system, which reveals the promising performance of our model.

This study investigated the variation in the intonation of Seoul Korean interjection ani across different meanings ("no" and "really?") and speech levels (Intimate and Polite) using data from Korean Intonation Corpus (KICo). The investigation was conducted in two stages. First, IP-final tones in the dataset were categorized according to the K-ToBI convention (Jun, 2000). While significant relationships were observed between the meaning of ani and its IP-final tones, substantial overlap between groups was notable. Second, the F0 characteristics of the final syllable of ani were analyzed to elucidate the apparent many-to-many relationships between intonation and meaning/speech level. Results indicated that these seemingly overlapping relationships could be significantly distinguished. Overall, this study advocates for a deeper analysis of phonetic intonation beyond ToBI-based categorical labels. By examining the F0 characteristics of the IP-final syllable, previously unclear connections between meaning/speech level and intonation become more comprehensible. Although ToBI remains a valuable tool and framework for studying intonation, it is imperative to explore beyond these categories to grasp the "distinctiveness" of intonation, thereby enriching our understanding of prosody.

본 연구에서는 재활정도를 정량적으로 표현하기 위하여 정상 보행과 모의 비정상 보행 시 보행주기에 따른 근전도 패턴에 고차 곡선 맞춤을 적용하여 분석하였다. 보행 근전도 패턴에 적합한 다항식을 생성하였으며, 그 변수를 군집분석 하여 5개의 그룹으로 분류하였다. 정상패턴을 포함한 그룹을 기준으로 거리가 가까운 그룹을 나열하여 각 변수의 분포를 확인하였다. 진폭감소 패턴, 불규칙 패턴, 역상 패턴 순으로 정상 패턴에 유사하였으며, 분류된 그룹의 분포는 중첩되는 범위가 작아 변수 값을 이용한 그룹 분류가 가능하였다. 분류된 재활정도를 정량적으로 나타내기 위하여 각 계수항의 표준편차를 패턴별로 비교하였고, 정상에 가까울수록 큰 값을 가지는 것을 확인하였다. 역상 패턴의 경우는 편차 값은 크지만 부호가 음의 값을 가지므로 가장 작았다. 본 연구의 결과인 정량적인 재활정도의 표현은 보다 효율적인 재활방법 연구에 기여할 것으로 예상된다.

As the frequency and the intensity of so called Asian dust (AD) events have increased, public concerns about the adverse health effects has spiked sharply over the last two decades. Despite the recent reports on the correlation between AD events and the risk for cardiovascular and respiratory disease, the nature of the toxicity and the degree of the risk are yet largely unknown. In the present study, we investigated the effects of the dichloromethane extract of AD (AD-X) and that of urban dust (NAD-X) collected during a non-AD period on gene expression in HL-60 cells using Illumina Sentrix HumanRef-8 Expression BeadChips. Global changes in gene expression were analyzed after 24 h of incubation with 50 or 100 ${\mu}g$/ml AD-X and NAD-X. By one-way analysis of variance (p < 0.05) and Benjamini-Hochberg multiple testing correction for false discovery rate of the results, 573 and 297 genes were identified as AD-X- and NAD-X-responsive, respectively. The genes were classified into three groups by Venn diagram analysis of their expression profile, i.e., 290 AD-X-specific, 14 NAD-X-specific, and 283 overlapping genes. Quantitative realtime PCR confirmed the changes in the expression levels of the selected genes. The expression patterns of five genes, namely SORL1, RABEPK, DDIT4, AZU1, and NUDT1 differed significantly between the two groups. Following rigorous validation process, these genes may provide information in developing biomarker for AD exposure.
