Purpose: The purpose of this study was to examine the experiences of the use of external breast prostheses among breast cancer survivors in Korea. Methods: A qualitative descriptive study was conducted, using focus groups. Data were collected from breast cancer survivors who were patients of C women's hospital in Seoul, Korea. Data were analyzed using content analysis in order to identify significant themes. Results: Participants included forty breast cancer survivors who had mastectomy as a surgical treatment. Four themes emerged from the collected data were: 1) concern over the high price of external breast prosthesis, 2) irregular use of external breast prosthesis, 3) unsatisfied with mastectomy bra, and 4) wanting to hide or not to talk about using breast prosthesis openly. Conclusion: Since most participants reported irregular use and negative experiences related to external breast prosthesis or mastectomy bra use, healthcare workers should allow more time for proper fitting and counseling and consulting with breast cancer survivors. In addition, health care providers as well as family and friends should keep in mind that cancer survivors need support that can help them cope by using positive reframing. Furthermore, improvements in the coverage of costs and services are needed for these women. This would be helpful for breast prosthesis users.

This study evaluates the changes of the subjective hand, preference, comfort and mechanical properties of tricot based artificial suede made from sea-island type micro fibers according to raising condition. The subjective hand and the preference of raised suede for jacket were rated by the 20's and 30's women experts according to raising cycles. Comfort properties were evaluated by air permeability, water vapor transmission, and thermal transmission. Mechanical properties were measured by the KES-FB system. The subjective hand of artificial suede was categorized into three hand factors: smoothness, warmness and thickness. Smoothness, warmness and thickness perception increased with raising cycles which affected hand preference and luxuriousness perception. The thickness and wale density of suede increased with the number of raising. Suede became more compact and less pliable and less stretchable due to increased fabric thickness; in addition, the surface of suede became smoother and compressive since the surface evenness of suede improved with smaller fiber fineness and an increased amount of naps covered the base fabric. Furthermore, water vapor transmission decreased and thermal insulation increased. The best raising conditions for artificial suede was four cycles in which artificial suede was preferred without changes in physical properties.

This paper presents a novel makeup simulation method for powder application. We propose a color appearance model for powder coated skin that is simple but yet capable of producing realistic visual results. From the photos of several artificial skins before and after powder application, the translucency and thickness parameters are achieved by fitting the color model to the photos. Thickness patterns of powder application on actual human face skin is also extracted, and used in makeup simulations on photos of different human face to give more visually appealing results. From experiments, we found that the simulation results are quite realistic, and expect that the proposed makeup simulation can be used as a virtual coloring test in the cosmetic labs.

Recently, as interest in environmental issues increases, minimizing carbon dioxide generated during cement manufacturing is a problem to be solved. In order to solve such a problem, it is required to use an industrial by-product of recycled aggregate, blast furnace slag, and circulating fluidized bed boiler fly ash to replace it on the basis of geopolymer(=cementless). This study examines the characteristics of eco-friendly artificial stone according to the mixing ratio of geopolymer-based recycled aggregate. As a result of the experiment, when the addition rate of the alkali stimulant was 15% and the mixing ratio of the circulating aggregate was 70%, the flexural strength and compressive strength were the highest. Density and water absorption decreased as density of circulating aggregates increased and water absorption increased. However, when the mixing ratio of the circulating aggregate exceeded 70%, the flexural strength and compressive strength decreased. Therefore, in order to obtain strengths meeting the KS standards, the mixing ratio of recycled aggregate was set to 70%, and artificial stone was manufactured using industrial by-products.

A lot of license plate data is required for car number recognition. License plate data needs to be balanced from past license plates to the latest license plates. However, it is difficult to obtain data from the actual past license plate to the latest ones. In order to solve this problem, a license plate recognition study through deep learning is being conducted by creating a synthetic license plates. Since the synthetic data have differences from real data, and various data augmentation techniques are used to solve these problems. Existing data augmentation simply used methods such as brightness, rotation, affine transformation, blur, and noise. In this paper, we apply a style transformation method that transforms synthetic data into real-world data styles with data augmentation methods. In addition, real license plate data are noisy when it is captured from a distance and under the dark environment. If we simply recognize characters with input data, chances of misrecognition are high. To improve character recognition, in this paper, we applied the DeblurGANv2 method as a quality improvement method for character recognition, increasing the accuracy of license plate recognition. The method of deep learning for license plate detection and license plate number recognition used YOLO-V5. To determine the performance of the synthetic license plate data, we construct a test set by collecting our own secured license plates. License plate detection without style conversion recorded 0.614 mAP. As a result of applying the style transformation, we confirm that the license plate detection performance was improved by recording 0.679mAP. In addition, the successul detection rate without image enhancement was 0.872, and the detection rate was 0.915 after image enhancement, confirming that the performance improved.
