The study mainly focused on textile evaluation criteria and clarified the relationship between the levels of clothing involvement and demographic variables. Subjects were 459 women living in JeonJu. SPSS package was used to analyzed the data. The main findings of this research were as follows: 1. Textile evaluation criteria such as the high quality of textile, the component of fiber, the easeness of care, and the durability of fabrics were used for the jackets and the coats. As regards the blouses and the shirts, the easeness of care, the high quality of fabric, the component of fiber, and the comfort of wearing, the easeness of care and the shape for better looks influenced the decision making process of consumers. 2. The subjectives were categorized into three groups depending upon the clothing involvement level. They have shown significant differences from demographic factors such as age, marrige, education, and occupation.

In this study, we investigated the electromagnetic properties of Mn-Zn ferrite doped with rare earth oxide (Dy$_2$O$_3$, Er$_2$O$_3$). The main composition is 52mo1% ${\alpha}$-Fe$_2$O$_3$, 25mol% Mn$_3$O$_4$ 23mo1% ZnO and doped with them(0.05wt% ∼ 0.25wt%, step:0.05wt%). An experimental process has advanced by conventional ferrimagnetism manufacturing that was prepared by standard ceramic techniques. The XRD pattern of all doped sample were observed spinel and secondary phase. The density of sample were measured nearly constant value. As increased the additive, resistivity, initial permeability and real component of the series complex permeability increased with setting limits each other. In case of Mn-Zn ferrite excess doped with them, resistivity, initial permeability and real component of the series complex permeability decreased and magnetic loss increased in proportion to increasing the additive.

This is a study on controlling a drone (DJI Mavic Air) with simple hand gesture using Leap Motion controller. Four component involve are MacBook, Leap Motion controller, Android device, and DJI Mavic Air. All of this component are connected through USB, Bluetooth, and Wi-Fi technology. The studies main purpose are to show that by controlling a drone through Leap Motion, drone amateur user can easily learn how to control a drone, and because of longer drone control range can be archived things such as search and rescue mission will be possible.

Planar magnetic based design technologies have been widely applied to power design for better cooling and ease of fabrication. The planar transformer and the planar inductor have a low profile characteristics compare to the conventional transformer which would be more cubical in volume. High frequency operation of magnetic components is a main key to achieve high power density of the power module. However, at a high frequency, the skin effect and the proximity effect have to be considered very significantly in magnetic design and also the parasitics in the converter cannot be ignored. This paper deals with the design and the experiment of planar integrated magnetic component. The optimal design for planar magnetics is summarized.

This study was conducted to evaluate the application possibility of environment-friendly rural toilet developed by NRLSI (National Rural Living Science Institute). The evaluation tests of rural toilet consist of composting efficiency, component analysis of odor, and economic efficiency. The test showed that the remaining quantity of wastes was only 14.7% during 10 months. The ammonium gas, main component of ill odor, was not measured, and the other components or odor were significantly detected less than those in pit toilet. The saved PVC (Present Value Cost) of the toilet management cost for thirty years is about 2,457,000 wons compared with flushing toilet supported by a single sanitation facility.

Objectives: The main purpose of this study is to analyze the importance of the rotatory factor in PNF pattern. In this article has to analyze and clarify the importance of the rotatory factor in PNF pattern by comparing the general concepts, facilitation technics, and neuroscience of muscle spindle, etc. Methods: This is a literature study with books. Results : There is close relationships between the pattern in PNF and rotatory factor. PNF pattern is priorily made up the diagonal and spiral pattern. the rotatory factor influences and guides from the start to end in the pattern. Conclusions : Rotation component is most important of the three component that one flexion or extension, abduction or adduction and rotation. It is that provide longer muscle length and stimulate the muscle spindles.

The fragments of a wall painting excavated from among the historical remains of Jeseoksa Temple in Iksan. The extent of the damage to the fragments was examined and an analysis of the components of the pigment was conducted. The results of the component analysis of the pigment confirmed that the white pigment consisted of alkali feldspar and mullite. Although the results of the visual inspection revealed differences in color in the red and black pigments, the main component of the two colors was confirmed to be iron oxide. Red and black pigments are found at the same position. Although differences of color is obvious, those are identified as hematite and magnetite of oxidized steel's affiliation. It is judged that Differences of ingredients happened by external environment's factors.

As the information age develops, Online education and Non-face-to-face work are becoming common. Telecommuting such as tele-education and video conferencing through the application of information technology is also becoming common due to the COVID-19. Unexpected information leakage can occur online when the company conducts work remotely or holds meetings. A system to authenticate users is needed to reduce information leakage. In this study, there are various ways to authenticate remote access users. By applying burn authentication using a biometric system, a method to identify users is proposed. The method used in the study was studied the main component analysis method, which recognizes several characteristics in facial recognition and processes interrelationships. It proposed a method that can be easily utilized without additional devices by utilizing a camera connected to a computer by authenticating the user using the shape and characteristics of the face by using the PCA method.

Lentinula edodes mushrooms cultivated under different relative humidities were wrapped at 4℃ and the results of storage characteristics were investigated. Changes in water content of fruiting bodies during the storage period showed the highest water content in fruit bodies harvested from the treatment with the highest relative humidity. The luminosity of the fresh fruiting bodies showed no significant change during the storage period, and the redness was higher in the relative humidity 95% treatment than in the other treatments. According to this study, the relative humidity of the pileus was 65%, and the content of Ergosterol was 0.67 ± 15 g / L at relative humidity of 65%, 80% and 95%. In addition, amino acid analysis and Principal Component Analysis (PCA) confirmed that methionine was the main cause of changes in storage time and relative humidity.

Prescriptions that Rhizoma Anemarrhenae was taken as a monarch drug are utilized for 21 therapeutic purposes, for example, cough, malaria, Sang Han syndromes and eye disease. In particular, 22.1% of prescriptions appear in the chapter of cough, and 13.2% of those appear in the chapter of malaria. Prescriptions that utilize Rhizoma Anemarrhenae as the main ingredient are used in the treatment of cough, asthma and malaria. Rhizoma Anemarrhenae is used in pathogenic factors such as fire, and used in pathology related to kidny system. The dosage of Rhizoma Anemarrhenae is 3bun(about 1.12 gram) to 3jeon(about 11.25 gram), however 1jeon(about 3.75 gram) has been taken the most for clinical application. Gamlihuan is the most useful base prescription which use the Rhizoma Anemarrhenae as the main ingredient.
