  • This paper is a study on the expression of Clothing and Textiles recorded in $\ulcorner Makuranosorsi(枕草子) \lrcorner$ This book was written by a Japanese servant in the Royal Court about the year 10000. In this book many kinds of clothing ornament color and materials were mentioned. The discoveries of this paper were as follows. 1. There were 85 different kinds of name In detail there were 46 Clothing and Accessories 32 Clors 11 Materials Patterns the method of Dyeing. 2. All the Clothing and Textiles in Makur-anosorsi were reflections of the reality of that times. 3. From ancient times japanse Costume was much influenced by Korea. but around the 7th century the influence increased. 4. Almost all clothing and Accessories used in Japan in the 10th century had been pre-viosly used in neighboring countries Korea and China But after they were imported to japan some of them were changed to japans hybrids especially in name and shape. 5. In Japan Clothing Colors were used in various ways sometimes colors coordinated by over lapping dress and othertimes the colors were weaved together Namely the width and length of these colorful fibres are also signifi-cant meaning. This meas that the Japanese was much more interested in color than other countries and this also proves Clothing Colors were very developed in japan by the 10th cen-tury. 6. The Materials discovered in this book were almost all silk This is the reason why $\ulcorner Makuranosorsi \lrcorner$ was the expression of the Royal Court.

  • Background: The two basic methods that are currently accepted to identify the HER2 status are immunohistochemistry and flyorescence in situ hybridization (FISH). The aim of this study was to perform the dual-color silver in situ hybridization (dc-SISH) technique as an alternative to FISH. Materials and Methods: A total of 40 invasive breast carcinoma cases were assessed for HER2 gene amplification by FISH and dual-color SISH. Results: Significant correlation was found in the HER2 expression results obtained with the two approaches (p=0.001, p<0.05). The concordance rate was 92.3%. Conclusions: Foutine practical use of the dc-SISH method, which is much easier to apply, score, and evaluate, has many advantages. HER2 and CEN17 status can be evaluated simultaneously with the newly developed "Dual-Color Probe". All these specifications and the reliable results obtained support the widespread use of SISH technique in clinical practice.

  • Due to the fluctuating random and periodical nature of renewable energy generation power quality disturbances occurred more frequently in power generation transformation transmission and distribution. Various power quality disturbances may lead to equipment damage or even power outages. Therefore it is essential to detect and classify different power quality disturbances in real time automatically. The traditional PQD identification method consists of three steps: feature extraction feature selection and classification. However, the handcrafted features are imprecise in the feature selection stage, resulting in low classification accuracy. This paper proposes a deep neural architecture based on Convolution Neural Network and Long Short Term Memory combining the time and frequency domain features to recognize 16 types of Power Quality signals. The frequency-domain data were obtained from the Fast Fourier Transform which could efficiently extract the frequency-domain features. The performance in synthetic data and real 6kV power system data indicate that our proposed method generalizes well compared with other deep learning methods.

  • Voice user interface has become a commercially viable and extensive interaction mechanism with the development of voice assistants. Despite the popularity of voice assistants, the academic community does not utterly understand about what, when, and how users chat with them. Chatting with a voice assistant is crucial as it defines how a user will seek the help of the assistant in the future. This study aims to cover the essence and construct of conversational AI, to develop a classification method to deal with user utterances, and, most importantly, to understand about what, when, and how Chinese users chat with voice assistants. We collected user utterances from the real conventional database of a commercial voice assistant, NetEase Sing in China. We also identified different utterance categories on the basis of previous studies and real usage conditions and annotated the utterances with 17 labels. Furthermore, we found that the three top reasons for the usage of voice assistants in China are the following: (1) greeting, (2) function, and (3) music. Chinese users like to interact with voice assistants at night from 7 PM to 10 PM, and they are polite toward the assistants. The whole percentage of negative feedback utterances is less than 6%, which is considerably low. These findings appear to be useful in voice interaction designs for intelligent hardware.

  • Genotype data from seven microsatellites typed in 231 animals were used to estimate the genetic structures of eight cow population distributed by regional area in Hanwoo (Korean cattle). In total, 53 alleles were detected from the genotyping of seven microsatellite markers. The average of expected heterozygosities ranged from 0.682 to 0.734 in 8 population of Hanwoo. Even though there were also some of alleles that were found in only specific regional population, similar frequency pattern for the most of alleles appeared in various 8 population. Genetic distances between populations were obtained using STDUPGMA method to construct a phylogenetic tree. The tree illustrated that most individuals were grouped on the basis of populations, distributed by the regional area. Some of genetic parameter on the basis of microsatellite gonotyping appears to provide a useful tool for examining the regional area kindship and genetic variation in Hanwoo.

  • Recently, most of the technologies have been developed in various forms through the advancement of single technology or interaction with other technologies. Particularly, these technologies have the characteristic of the convergence caused by the interaction between two or more techniques. In addition, efforts in responding to technological changes by advance are continuously increasing through forecasting promising convergence technologies that will emerge in the near future. According to this phenomenon, many researchers are attempting to perform various analyses about forecasting promising convergence technologies. A convergence technology has characteristics of various technologies according to the principle of generation. Therefore, forecasting promising convergence technologies is much more difficult than forecasting general technologies with high growth potential. Nevertheless, some achievements have been confirmed in an attempt to forecasting promising technologies using big data analysis and social network analysis. Studies of convergence technology through data analysis are actively conducted with the theme of discovering new convergence technologies and analyzing their trends. According that, information about new convergence technologies is being provided more abundantly than in the past. However, existing methods in analyzing convergence technology have some limitations. Firstly, most studies deal with convergence technology analyze data through predefined technology classifications. The technologies appearing recently tend to have characteristics of convergence and thus consist of technologies from various fields. In other words, the new convergence technologies may not belong to the defined classification. Therefore, the existing method does not properly reflect the dynamic change of the convergence phenomenon. Secondly, in order to forecast the promising convergence technologies, most of the existing analysis method use the general purpose indicators in process. This method does not fully utilize the specificity of convergence phenomenon. The new convergence technology is highly dependent on the existing technology, which is the origin of that technology. Based on that, it can grow into the independent field or disappear rapidly, according to the change of the dependent technology. In the existing analysis, the potential growth of convergence technology is judged through the traditional indicators designed from the general purpose. However, these indicators do not reflect the principle of convergence. In other words, these indicators do not reflect the characteristics of convergence technology, which brings the meaning of new technologies emerge through two or more mature technologies and grown technologies affect the creation of another technology. Thirdly, previous studies do not provide objective methods for evaluating the accuracy of models in forecasting promising convergence technologies. In the studies of convergence technology, the subject of forecasting promising technologies was relatively insufficient due to the complexity of the field. Therefore, it is difficult to find a method to evaluate the accuracy of the model that forecasting promising convergence technologies. In order to activate the field of forecasting promising convergence technology, it is important to establish a method for objectively verifying and evaluating the accuracy of the model proposed by each study. To overcome these limitations, we propose a new method for analysis of convergence technologies. First of all, through topic modeling, we derive a new technology classification in terms of text content. It reflects the dynamic change of the actual technology market, not the existing fixed classification standard. In addition, we identify the influence relationships between technologies through the topic correspondence weights of each document, and structuralize them into a network. In addition, we devise a centrality indicator (PGC, potential growth centrality) to forecast the future growth of technology by utilizing the centrality information of each technology. It reflects the convergence characteristics of each technology, according to technology maturity and interdependence between technologies. Along with this, we propose a method to evaluate the accuracy of forecasting model by measuring the growth rate of promising technology. It is based on the variation of potential growth centrality by period. In this paper, we conduct experiments with 13,477 patent documents dealing with technical contents to evaluate the performance and practical applicability of the proposed method. As a result, it is confirmed that the forecast model based on a centrality indicator of the proposed method has a maximum forecast accuracy of about 2.88 times higher than the accuracy of the forecast model based on the currently used network indicators.

  • The present research is to study the make-up culture of Korea and its neighboring countries such as China and Japan during the period from the prehistoric age to the 19th cen-tury. The research was made by documents analysis. The results are summerised as follows : (1) A man has a basic instinct to beautify himself. There was not a significant difference between the make-up behavior of men and women in its primal stage. It was by the start of farming and the division of labor that made the make-up behavior as a feminine culture. The difference of sexual role caused the con-ceptual difference between manly beauty and womanly beauty. It was very natural for women to regard the make-up as the best way for showing their feminine beauty. In Korea, China and Japan, there were vari-ous kinds of primal actions such as tattooing, body-painting, and tooth make-up which were used in the purpose of body protection, incantation, ornament, and so on. Ass their ornamental purpose was becoming more important, these primal actions became the basis of the feminine make-up culture. Nowadays make-up, having mental and emo-tional function, is helpful to increasing self-satisfaction, promoting good personal relation-ship, and attracting attention from the other sex. It also has other functions of showing social status, wealth, age, sex, courage, power, and so on. (2) The representative make-up product used widely in the three countries was Boon (powder) which decides the overall color of face. The key point in the production of Boon was to increase its power of adsorption. The invention of Yunboon (power mixed with lead) solved this major problem of Boon. Yeonji which decides the color of cheek was the mixture of Boon and the powder of Honghwa (a kind of red-colored flower or tree). Mimook (eyebrow pencil) was developed to match up with the various and changing currencies of penciling eyebrows in each nation and times, Yeonji and Joosa (red sand) were used as Jinji (lip stick). The predominant color of Jinji was red. As miscellaneous methods of partial make-up, there were Kon-ji used in a wedding cer-emony in korea, Aek-hwang, Hwa-jeon, Sa-hong, and Myun-yup in China, and Chi-heuk, a peculial method of partial make-up in japan. (3) There were various factors which decided the characteristics of make-up culture usually reflects international atmosphere, the form of government, economic situation, re-ligious and social ideology, aesthetic sense, symbolizing meanings of colors, and so on. The up and down of an influentian country was one of the major factors which decided the characteristics of the make-up culture of its neighboring countries. When a country took a liberal form of government, it had diverse and splendid tendencies in its make-up culture. The better a nation's economic situation is, the more abandant and various its make-up culture is, and sometimes, the more eccentric and decadents it was. In the field of make-up production, the three countries had their own characteristics. But, as a whole, China was the leading nation who spread the culture and products of make-up to Korea and Japan. Though the Chinese make-up culture and products were usually spread to Japan through Korean, there was some evidence of direct exchanges between China and Japan through its dispatches of Kyun-Tang-Sa(Japanese delegation to the Tang Dynasty). While religion had a positive influence on the development of make-up culture by introducing new methods of make-up, Confucianism exercised strict control over the make-up cul-ture. The currencies in arts and changes of esthetic sense introduced new methods and booms to the make-up culture. Literature made people pay increasing attentions to the countenances of women and changed the standards of esthetic sense. We can find out that the social status of woman was also reflected in the make-up culture. As the social status of women became higher, the feminine make-up culture also developed more then ever. As mentioned above, the make-up cultures of the three countries reflected their social values, esthetic senses, and emotional feelings. Through their cultural exchanges, the three countries could develop various make-up products and methods.

  • This research was conducted to evaluate the occurrence of ochratoxin A (OTA) in coffee and fruit products in Korea. A total of 388 coffee and fruit product samples were collected from retail or outlet markets; 177 samples were coffee and 211 were fruits or their products. Analytical methods including AOAC and Comit$\acute{e}$ Europ$\acute{e}$en de Normalisation (CEN) were selected and modified by method validation to detect and quantify the OTA in samples. All samples were analyzed by liquid chromatography with fluorescence detection. OTA was detected in 3.9% of 177 kinds of coffee and 0% of 211 kinds of fruit products. The levels of OTA were $0.7-4.6\;{\mu}g/kg$ in green coffee, $0.3-4.8\;{\mu}g/kg$ in roasted coffee, $1.4\;{\mu}g/kg$ in mixed coffee, and $0.4-0.6\;{\mu}g/kg$ in instant coffee. However, OTA was not detected in liquid coffee, dried fruits, or grape juice. OTA levels of all samples detected were less than the European Union legislation of $5.0\;{\mu}g/kg$ in coffee, $10.0\;{\mu}g/kg$ in raisins and $2.0\;{\mu}g/kg$ in grape juice. Therefore, the risk of OTA in coffee and fruit products in Korea is relatively low at safe levels.
