The purpose of this study was to examine the differences in image perception, and to investigate the differences in age and income inferences according to the wearing of accessories with black dress. A quasi-experimental method was used for this study. The experimental design was a $2{\times}3{\times}3$(necklace${\times}$earrings${\times}$corsage) factorial design. The subjects were 610 female college students residing in Seoul. The model in the stimulus photographs was a woman with straight long hair. She wore a black one-piece dress with round neckline and short sleeves. The findings indicated that the wearing of a necklace enhanced individuality, attractiveness, and cuteness in women. Professionalism and individuality were heightened when she wore an earring. The red corsage enhanced individuality, but it had a negative effect in professionalism. As for the effect on interaction, attractiveness was more highly perceived when both necklace and large earrings were worn without a corsage. The absence of both necklace and earrings led to a low perception of professionalism, attractiveness, and individuality. The wearing of a necklace was more strongly linked to older age and high income than not wearing it, and it was perceived as more youthful if earrings were not worn. As for interactions, the wearing of small earrings and a red corsage was linked to the oldest age.

For the discussion of palaeogeomagnetic field direction and the movement and rotation of geotectonic blocks it is prerequisite to eliminate the secondary remanent magnetization component out of the NRM vector of given rock samples. Among various techniques alternating field and thermal demagnetization methods are most easily applicable and most widely used ones. Physical principle underlying these methods is the concept of relaxation time: Either with an action of external magnetic field or with an elevated temperature relaxation time of magnetic minerals can be drastically shortened. It has been furthermore shown experimentally that the secondary remanent magnetization can be more easily demagnetized than the primary remanent magnetization. Through careful stepwise demagnetization it should also be possible to discriminate the kind of various remanent magnetizations. In addition to the introduction to the underlying physical principles and experimental results of the alternating field and thermal demagnetization this paper gives various practical tips in earring out the demagnetization experiments. Each alternating field and thermal demagnetization instrumentation which is easily adaptable to domestic palaeomagnetic laboratories is also introduced. This paper provides a compact and practical introduction to the methods in palaeomagnetism and would be of interest to present workers and to those who want to embark on research in this field.

This study defines attributes of the Korean costume culture, focussed on hair, shoes and accessories which express sex-roles, encapsulated in the term, “be like...”. A group of 362 male and female university students from Seoul and Gyeonggi area was surveyed for the study. The statistical analysis of SPSS 10.0 was applied for analyzing the data, and the significant variances were reviewed by the basic statistics and t-test. The results are as follows; First, short hair is perceived as the typical hair style that symbolizes male, both from male and female university students. Hair colors in warm color such as brown, wine, purple, lemon and orange, and the style of hair such as bobbed, long, and perm are perceived as definite clues that symbolized female. Second, when it concerns the types of shoes, both male and female university students cited oxford as the typical clue that symbolizes male, whereas pumps and sandal were cited for female. Third, in terms of types of accessories, both male and female university students perceived necklace, earring, bracelet, hair pin and band, scarf, and muffler as very feminine. Among these, hair pin and band, and scarf are evaluated as the typical clues that signify the role of females. Necktie is perceived as the typical clue that signify male role.

One of the main objectives of researches for the chemical grouting is to assess the changes in soil properties caused by injection of chemical grout. Especially the changes in the strength properties of soils, such as elastic modulus, shear modulus of ground due to injection of chemical grout has drawn our attention. Since the specific surface changes with variation in the grain size of sandy soil, the influence of grain size of sandy toil on the strength and stiffness of silicate-grouted soil was investicated in this study by earring out uniaxial and triaxial compression tests. It was found that the strength and stiffness of grouted soil increased as the grain size of sandy soil decreases, the possibility of estimating the strength of grouted soil was confirmed through the study of relationship between specific surface of sandy soil and the strength of chemical gel.

This paper proposed a real-time earlobe detection system using deep learning on the web. Existing deep learning-based detection methods often find independent objects such as cars, mugs, cats, and people. We proposed a way to receive an image through the camera of the user device in a web environment and detect the earlobe on the server. First, we took a picture of the user's face with the user's device camera on the web so that the user's ears were visible. After that, we sent the photographed user's face to the server to find the earlobe. Based on the detected results, we printed an earring model on the user's earlobe on the web. We trained an existing YOLO v5 model using a dataset of about 200 that created a bounding box on the earlobe. We estimated the position of the earlobe through a trained deep learning model. Through this process, we proposed a real-time earlobe detection system on the web. The proposed method showed the performance of detecting earlobes in real-time and loading 3D models from the web in real-time.

This study aimed to evaluate the user experience of hearable devices for seniors and suggest possible development directions. A literature review, case study, and in-depth interviews were conducted. Based on the literature review, convenience, accessibility, transmissibility, wearability, aesthetics, and interest were determined as the user experience factors of hearable devices. Then, in-depth interviews were conducted with 12 participants aged 60 or older regarding four devices. Participants tried four different types of wireless earphones which were selected based on a case study: open-type, kernel-type, neckband-type, and earring-type. Regarding convenience, the participants preferred to carry small devices and regarding accessibility, participants responded positively for most product types. For transmissibility and wearability, there were differences depending on whether devices were put on correctly, but the participants preferred products that did not wholly block external sounds. For aesthetics, participants preferred small and cutting-edge designs. Interest was noticeable among those who had not used the devices before, and for stability, the neckband-type was the most preferred. Based on the results we suggest designing small cutting-edge designs and button-type assist devices, not blocking the external sound, providing a participation program, simplifying device functions, and establishing a method that can be combined with and stored in clothes and a delivery method that can signal danger.
