This study aims to explore consumers' perception regarding "one-mile wear" and "home wear" fashion, an emerging trend during the Coronavirus disease (COVID-19) pandemic, and to identify the changes in consumers' perception of this style before and after the pandemic. The data collection period was set as one year before and after the outbreak as of January 1, 2020, and blog posts with keywords "one-mile wear" and "home wear" were collected. Further, textual data crawled and refined using Python 3.7 libraries, and centralities were measured and visualized through NodeXL 1.0.1 and Ucinet 6. According to the results, first, consumers' perception regarding one-mile wear fashion was divided into the following eight categories: wearing situation, expected attribute, style, item, color, textile, shape, and target wearer. Second, before the pandemic, home wear was recognized as pajamas or indoor wear; after the pandemic, home wear was recognized as one-mile wear, outdoor wear, and daily wear. Moreover, keywords, such as "telecommuting", "social distancing", "untact", and "upper body", appeared after the pandemic. It was confirmed that consumers' perception of home wear was affected by the pandemic.

Kodály hand signs are symbols that intuitively represent pitch and note names based on the shape and height of the hand. They are an excellent tool that can be easily expressed using the human body, making them highly engaging for children who are new to music. Traditional hand signs help beginners easily understand pitch and significantly aid in music learning and performance. However, Kodály hand signs have distinctive features, such as the ability to indicate key changes or chords using both hands and to clearly represent accidentals. These features enable the effective use of Kodály hand signs. In this paper, we aim to investigate the changes in recognition rates according to the complexity of scales by creating a device for learning Kodály hand signs, teaching simple Do-Re-Mi scales, and then gradually increasing the complexity of the scales and teaching complex scales and children's songs (such as "May Had A Little Lamb"). The learning device utilizes accelerometer and bending sensors. The accelerometer detects the tilt of the hand, while the bending sensor detects the degree of bending in the fingers. The utilized accelerometer is a 6-axis accelerometer that can also measure angular velocity, ensuring accurate data collection. The learning and performance evaluation of the Kodály learning device were conducted using Python.

Recently, the occurrence and death rates of cancer have increased rapidly. In oriental medicine, the tongue gives some kind of special physiological information on human body. Oriental medical doctors have used information about the color, degree of wetness and shape of the patient's tongue to determine patient's disease and body condition. This fact leads us that the tongue image is one of the most important clinical data for helping doctor's decision making. It also has significant meaning to cancer patients related with traditional theory of oriental medicine. In diagnosis and treatment of cancer, tongue diagnosis can give some prognosis and change o cancer. It also detect the sign of early stage cancer, but it cannot diagnose the kind of cancer and/or benign or malignant. Nowadays BioTechnology(BT) has developed rapidly, but there are a lot of limits(economy, accuracy, clinical significance, etc). Tongue diagnosis is very economic and practical way of diagnose and has a lot of possibility of development. The need for doctors and it also helps the development of tongue diagnosis related with cancer.

This research used a questionnaire to provide basic data for the design of dressing form that enables the manufacture of senior menswear with an improved fit to match the dissatisfaction with the fit of male suits over the 50s. We used 132 questionnaires as analytical data. The results were: The item 'purchasing method of formal suits' showed that 95.5% purchased ready-to-wear jackets. The 'abdominal obesity type' and 'trunk waist type' had a high frequency of 'complaints about the size of the ready-to-wear jacket'. They choose their suits and wear them directly from the store. It is expected that senior males will complain about ready-to-wear formal suits due to the increase in girth item than normal type due to change of body shape since they consider size to also be important when purchasing suits. The most important part of the body when purchasing suits is the shoulder area, followed by the front width and back width of the fit. As for the degree of recognition of suit size, 38.1% said that they know the size and 'Suit size is hard to understand'. As a result of dissatisfaction with formal dressing, the items of 'Neck wide of get loose', 'Drag line of back neck', 'Not fit of front opening', 'Not fit of shoulder slope' and 'dissatisfaction'. Therefore, it is salient to establish suit fitting system and size system for senior men.

Titanium and its alloys that have a good biocompatibility, corrosion resistance, and mechanical properties such as hardness and wear resistance are widely used in dental and orthopedic implant applications. They can directly connect to bone. However, they do not form a chemical bond with bone tissue. Plasma electrolytic oxidation (PEO) that combines the high voltage spark and electrochemical oxidation is a novel method to form ceramic coatings on light metals such as titanium and its alloys. This is an excellent reproducibility and economical, because the size and shape control of the nano-structure is relatively easy. Silicon (Si), manganese (Mn), and magnesium (Mg) has a useful to bone. Particularly, Si has been found to be essential for normal bone, cartilage growth and development. Manganese influences regulation of bone remodeling because its low content in body is connected with the rise of the concentration of calcium, phosphates and phosphatase out of cells. Insufficience of Mn in human body is probably contributing cause of osteoporosis. Pre-studies have shown that Mg plays very important roles in essential for normal growth and metabolism of skeletal tissue in vertebrates and can be detected as minor constituents in teeth and bone. The objective of this work was to study nucleation and growth of bone-like apatite formation on Ti-6Al-4V in solution containing Mn, Mg, and Si ions after plasma electrolytic oxidation. Anodized alloys was prepared at 270V~300V voltages. And bone-like apatite formation was carried out in SBF solution for 1, 3, 5, and 7 days. The morphologies of PEO-treated Ti-6Al-4V alloy in containing Mn, Mg, and Si ions were examined by FE-SEM, EDS, and XRD.

Objectives : This paper aims to understand the meaning and utilitarian values of 'Jongyong(從容)' in medicine by studying its meaning in the 『Huangdineijing』. Methods : Examples of 'Jongyong(從容)' usages in Chinese literature and classical texts were studied first. Next, the similarities and characteristics of its contexts in discourses between Leigong and Huangdi were examined, followed by further examination of the overall meanings of the six chapters, 「Shicongronglunpian(示從容論篇)」, 「Zhuzhijiaolunpian(著至敎論篇)」, 「Shuwuguolunpian(疏五過論篇)」, 「Zhengsishilunpian(徵四失論篇)」, 「Yinyangleilunpian(陰陽類論篇)」, 「Jiejingweilunpian(解精微論篇)」 and the verses that include 'Jongyong(從容).' Results : Generally 'Jongyong(從容)' describes a resilient attitude that responds appropriately and calmly to difficult external situations while maintaining one's character, or refers to one's general behavior. In the 『Huangdineijing』, 'Jongyong(從容)' is only mentioned in discourses between Leigong and Huangdi, which talks about ancient East Asian clinical medicine in general, its transmission and education. Here, the meaning of 'Jongyong(從容)' could be summarized as an expansion of analogical thinking[引比類], medical work that involves the physician's commitment(人事), and detailed measurement of yinyang difference in the body(刑法, 陰陽, 治數). Discussion : In ancient East Asian medicine, the meaning of 'Jongyong(從容)' is closer to measurement of the yinyang difference rather than differentiation of the five element analogy. It is a medical practice that measures the shape, volume, length, area, height, concentration etc. of the human body in numerical figures to allow for the most subtle comparison, which was an important aspect of the physician's work that needed to be demonstrated, educated and transmitted to later generations to enable continuity of the medical profession.
