Concrete surfaces have weak surface strength due to bleeding and laitance, and problems such as peeling, cracking, and cracking may occur. In particular, underground parking lots can be said to be more vulnerable to peeling, breaking, and cracking if excessive loading of materials and equipment movement are not managed at the initial age after placing of concrete. Cracks, peeling, and cracking problems in slab concrete in underground parking lots of apartments can lead to leakage problems and affect finishing materials constructed on top of topping concrete, reducing the performance required for waterproof materials. Therefore, in this study, the bleeding and surface strength according to the standard of topping concrete and the use of admixture were reviewed to solve the crack, peeling, and cracking problems among the types of defects in underground parking lot slab concrete. As a result, it was derived that the optimal concrete compressive strength is 30MPa or more, and it is a reasonable performance design method to prohibit the substitution of admixtures.

This study investigates the suitability of outdoor wear among female trekkers in their twenties or thirties and provides data for developing outdoor wear more suitable for young females. Recently climbing has gained popularity as a leisure activity to enjoy the beauty of nature that increases physical and mental stamina. A survey was conducted on 304 female consumers in their twenties and thirties who enjoyed climbing in order to investigate the suitability of outdoor wear among young female consumers. The questionnaire covered the subjects' demographic information, duration and goal of climbing, purchase and suitability of outdoor wear, and preferred design for outdoor wear. As for the yearly situations, when they utilized outdoor wear, the biggest number of respondents chose "autumn" as the season for climbing. Most of the respondents were non-professional trekkers who enjoyed climbing as a hobby or for health. As for the size, the upper garment was 90 and 85 in the order, and the lower garment was 70 and 67 in the order. The pants were the most common item they owned, followed by round T-shirts, windbreaker jackets, zipup T-shirts, and waterproof jackets. They mentioned moisture absorption and dry fabric breathability as the basic functions required of outdoor wear. The subjects displayed a preference for partial details under the design category. They most preferred the hood-type jacket with a detachable stand collar, the sleeve hem with a partial rubber band and velcro strap, a T-shirt with a stand color and zipper, the waist fit with proper room, pants with a partial rubber band waist, and straight silhouette pants.

This study aims to analyze the characteristics of the male products for urinary incontinence by examining the types and characteristics of those registered in KIPO (Korean Industrial Property Office). Additionally, the types and characteristics, especially for the cloth products and the pads, of male panties for urinary incontinence on the market are analyzed. Men in their 60s with minor symptoms were selected as the subjects to evaluate the wearability. The results are as follows. 11 male products for urinary incontinence, registered in KIPO, are structurally different from those for women by having a separate pocket mainly for absorption. There are one disposable type and 7 cloth types, and the cloth panties can be classified as either united or separable type depending on the detachability of pads from the panties. The types of the panties vary according to the position, shape, and size of the attached pads on normal male panties (boxer, briefs, drawers). The fabrics for the urinary incontinence are usually piled in 3 to 5 layers by having the most absorptive layer on the top, the next with deodorizing characteristics, and the bottom with the waterproof fabric as basics with some additional layers of antibiotic or breathable fabrics. From the wearability test, it has been determined that the panties are not distinguishable in external appearance and the fitness is also not a problem since the size varies as the normal panties. It has been evaluated that the fitness of the panties is an important factor since the pad should be worn in any form; the pad sewed in the middle of the panties was evaluated to be more wearable than having a long pad. In case of separable panties, when the pattern and fabric is similar to the functional panties and the options such as the thickness of the pads or detachability are given to the users, it tends to be more satisfactory.

We determined the feasibility of a fishing camera system using an optical fiber as the fishing line by testing a power-over-fiber (POF) module and multimode optical fiber. Operation of the remote camera module (RCM) without the battery was preferred because the removal of the charging or battery replacement section enabled a waterproof single-body type design. The average efficiency of the photovoltaic power converter (PPC) in the tested POF module was 32.6% at 820 nm, and thus, a high-power laser of at least 1.27 W was required for operating the developed RCM with an electrical dissipation of 413 mW. Because the optical fiber was wound on a fishing reel, composite loss composed of bending and tensile loss occurred. To mitigate the composite loss, we employed a simple holder that showed an improvement in the composite loss of 0.38 dB to 0.8 dB, which was considerably better than the losses without the holder.
