To investigate the prevalence of Staphylococcus aureus (S. aureus) during production of perilla leaves, a total of 261 samples, including water, soil, surroundings of cultivation and packing, workers, and perilla leaves, was examined.. To trace the contamination sources of S. aureus related to perilla leaves, MLVA (Multi-Locous Variable number of tandem repeat Analysis), which is a very efficient method to discriminate strains with minimum molecular biology equipment was applied to S. aureus isolated from perilla leaves farms. S. aureus was isolated in perilla leaves from 9 of 38 farms at 0-2.92 log CFU/g. S. aureus was also found in working environment, including packing vinyl, worker clothes, irrigation water and hands. The patterns of MLVA of isolates from perilla leaves matched with those of isolates from packing table, irrigation water, packing vinyl, and hands. The isolates were successfully examined and determined by MLVA, thus elucidating S. aureus source and spread.

This study focuses on the funeral rites for Queen Wongyeong during the early Joseon period as part of a review of the changes in the state funeral system and ceremonial procedures. Conducted by the king in his role as chief mourner, the state funeral for King Taejong's wife Queen Wongyeong that emerged during the 2nd year of King Sejong marked the first example recorded in the sillok (Annals of the Joseon Dynasty) of the three year-mourning rite being applied. In terms of the clothing for the state funeral, the significance of Jolgok (a rite conducted on the 100th day following the day of death) was emphasized, while the existing yeokwolje (period of wearing mourning clothes, one month was equated with one day) was abandoned. The existing temporary office system for state funerals was reorganized into a three-office system consisting of the Binjeon dogam (Office for Chapel of Rest), Gukjang dogam (Office for Funeral Rites), and Salleung dogam (Office for the Establishment of Royal Tombs). Buddhism-related rites greatly decreased and were increasingly regulated. The ceremonial procedures were also modified in accordance with the rites directly conducted by the king during the three-year mourning period. The basic pattern of the ceremonial procedure consisted of kneeling / wailing - salute - kneeling/ wailing, and, based on the wuje (rites to console the deceased), was divided into 'make offerings to the deceased' (奠, jeon) and 'hold a memorial service for the deceased' (祭, je). This reflected the differing perceptions of jeon (奠) and je (祭) following the establishment of auspicious rites (gillye) during the reign of King Taejong. In short, the state funeral for Queen Wongyeong provides materials with which to analyze the establishment of the funeral rites and ceremonial procedures designed based on the actual three-year mourning period observed by the king, study the ritual ceremonies conducted during the ancient period, as well as foster an understanding of ancient systems.

This article is considered how to utilize mime in the mudang gut. Actually, mime can't be the crux of mudang gut, and the only factors of mime is utilized. Therefore, the purpose of this article is to draw another nets of meanings in Mudang gut, not to study mime. First of all, I surveyed the constituent factors of mudang gut. One gutpan is combined with various factors. As a shamans(mudang), a musician, a jang gu player, a gongyangju(taking charge of food), a sibongja(helper for a shaman), and madangsoe (an under servant), they played their roles. The gut consists of equipment, food, clothes, music and dance. Next, I derived two nets of meaning out of considering a mudang gut performance of mudang (shaman). First, god in a general gutgeori appears expressing their existence by using mime with the music. Second, the following god appears expressing themselves using only mime without music. After showing who he is through action and facial expression, he continues to play a gut. Accordingly, mime of seoul gutpan plays a role to reveal the existence of god. Also, I divided the way of performing mudang gut into language performance and motions and then suggested that mime was mainly used in the motions. I surveyed a gutgeori using mime in the concrete. Through this, I suggested that the shaman used mime, when sending a deadman to the next world in a Jinogi gut. I suggested that mime was utilized repeatedly at the process of repelling the misfortune in a jaesu gut.

Sleep apnea, a medical condition associated with a variety of complications, is generally monitored by standard sleep polysomnography, which is expensive and uncomfortable. To overcome these limitations, this study proposes an unconstrained wearable monitoring system with stretch-fiber sensors that integrate with the wearer's clothing. The system allows patients to undergo examinations in a familiar environment while minimizing the occurrence of skin allergies caused by adhesive tools. As smart clothing for adult males with sleep apnea, long-sleeved T-shirts embedding fibrous sensors were developed, enabling real-time monitoring of the patients' breathing rate, oxygen saturation, and airflow as sleep apnea diagnostic indicators. The gauge factor was measured as 20.3 in sample 4. The maximum breathing intake, measured during three large breaths, was 2048 ml. the oxygen saturation was measured before and during breath-holding. The oxygen saturation change was 69.45%, showing a minimum measurable oxygen saturation of 70%. After washing the garment, the gauge factor reduced only to 18.0, confirming the durability of the proposed system. The wearable sleep apnea monitoring smart clothes are readily available in the home and can measure three indicators of sleep apnea: respiration rate, breathing flow and oxygen saturation.

Red ocher, red lead or cinnabar has been as red colorant for ages. Cinnabar of the red pigments has been highly regarded as a valuable ingredient because it represent a symbol of exorcising and a haute image. It was used as a pigment of painting and mural painting, bowl, clothes, rock writing, gravestone, etc. It is powder which dissolves in perilla oil or glue before using. Because it is high-priced, the use of cinnabar may be limited to the privileged class. Therefore, red ocher or red lead was used instead of cinnabar. "Gongsagyunmunrok" demonstrated that government official's gravestonea has been painted red by two colorants in the period of the Goryeo dynasty. However, cinnabar may be used to paint gravestones for the first time in the period of the Three States because it has been transmitted since the times. This study discuss the results obtained from an analysis of the pigments used on the red pigments of the Stone Monuments. The results can be briefly summarized as below; First, the microcrystalline structures seen on the surface section of analyzed pigments, samples of which were taken from various parts of red pigments show that different sizes and shapes of pigment particle. Second, a result of the analysis on the composition and structure of the pigments shows that the main components in their composition are : Red pigments - Red lead($Pb_3O_4$), Cinnabar(HgS) and Hematite($Fe_2O_3$) White pigments - Calcite($CaCO_3$) Especially, we knew that red Stone Monuments were found to be natural mineral pigments, which were used as a singular or a mixture.

[Introduction] Nowadays, many companies are shifting their businesses online due to the growing trend among customers to buy and shop online, as people prefer online purchasing products. [Problem] Users share a vast amount of information about products, making it difficult and challenging for the end-users to make certain decisions. [Motivation] Therefore, we need a mechanism to automatically analyze end-user opinions, thoughts, or feelings in the social media platform about the products that might be useful for the customers to make or change their decisions about buying or purchasing specific products. [Proposed Solution] For this purpose, we proposed an automated SentiDecpective approach, which classifies end-user reviews into negative, positive, and neutral sentiments and identifies deceptive crowd-users rating information in the social media platform to help the user in decision-making. [Methodology] For this purpose, we first collected 11781 end-users comments from the Amazon store and Flipkart web application covering distant products, such as watches, mobile, shoes, clothes, and perfumes. Next, we develop a coding guideline used as a base for the comments annotation process. We then applied the content analysis approach and existing VADER library to annotate the end-user comments in the data set with the identified codes, which results in a labelled data set used as an input to the machine learning classifiers. Finally, we applied the sentiment analysis approach to identify the end-users opinions and overcome the deceptive rating information in the social media platforms by first preprocessing the input data to remove the irrelevant (stop words, special characters, etc.) data from the dataset, employing two standard resampling approaches to balance the data set, i-e, oversampling, and under-sampling, extract different features (TF-IDF and BOW) from the textual data in the data set and then train & test the machine learning algorithms by applying a standard cross-validation approach (KFold and Shuffle Split). [Results/Outcomes] Furthermore, to support our research study, we developed an automated tool that automatically analyzes each customer feedback and displays the collective sentiments of customers about a specific product with the help of a graph, which helps customers to make certain decisions. In a nutshell, our proposed sentiments approach produces good results when identifying the customer sentiments from the online user feedbacks, i-e, obtained an average 94.01% precision, 93.69% recall, and 93.81% F-measure value for classifying positive sentiments.

The Yongjam of Oejae, Yi Dan-ha's wife, is an ornamental hairpin with a dragon-shaped engraving; designated as National Folklore Cultural Heritage No. 4. It is also a component of the ceremonial costume, and an artifact of great value as it clearly identifies the position of the wearer and the period of this artifact. The Yongjam has been well preserved in general; however, various pollutants and corrosive products have affected the engraved patterns, requiring conservation treatment. Furthermore, a non-destructive analysis was conducted to identify the components of the materials and the manufacturing techniques used in the ornament. The Yongjam is hollow inside to reduce its weight when placed in the hair and has a color contrast of gold, red, and black. The decorative part and the body were made separately. That is, the body was made from an alloy of copper, silver, and zinc, and its joint was elaborately connected without any overlaps. In the decorative part, different alloy ratios were identified in the dragon's face, beard, horn, body, and fin. Further, for the dragon's face with its delicate patterns, an alloy of silver and copper was used, likely to make the face appear as realistic as possible.

The mechanical properties of a woven fabric made of SiC (silicon carbide) fibers were determined in this study using the KES-FB system. The woven fabric is used in high heat settings above 1500℃. Composite spun yarns were used to create SiC fibers. By analyzing the wearing properties, we studied the prospect of using the textiles as fire-retardant work clothes. Mechanical properties determine the wearing attributes. Therefore, the tensile linearity (LT), tensile resilience (RT), and shear stiffness (G) values of the fabric varied according to the yarn type (filament or spun yarn). The thickness, weight per square meter, and density of the fabric were found to have an effect on the shear hysteresis (2HG) and compression resilience (RC) values. In terms of wearable clothing qualities, the fabric qualities of the SiC composite yarn demonstrated the highest ratio of compressive energy to thickness (WC/T), which indicates bulkiness. The fabric manufactured from SiC composite yarns passed the KFI criteria for carbonation length and cumulative flame time in the flame-retardant test. Therefore, we discovered that the material can be used as a fire-resistant work cloth.

This study proposes an evaluation item model for the avatar expression process, satisfaction and self-identification for each expression element in order to investigate the expression attributes on the influence on the user in setting the avatar. The evaluation of avatar expression method was composed of self-identification and satisfaction by ease of expression and expression elements on the avatar production and expression process. To evaluate the proposed evaluation model, 17 people participated in the experiment. As a result, it was found that most of the participants had a high level of understanding of the production process, and the more diverse the expression elements, the higher the satisfaction with the avatar expression process. Hair shape and face shape were the most important expression factors, and clothes and overall harmony was the most concerned facotrs. Most of them tried to express themselves as realistically as possible. However, in self-identification, there was no significant correlation between expression and production process. In this study identify the decision-making factors that appear in the avatar expression process, the direction in which satisfaction can be formed, and the factors that affect self-identification. In addition, it will be a basic study on how avatars have a lasting influence on users in the future.
