It is difficult to differentiate acute skin failure (ASF) from pressure ulcer (PU). ASF is defined as unavoidable injury resulting from hypoperfusion caused by severe dysfunction of another organ system. We describe a case of ASF mistaken as PU that resulted in a legal dispute. A 74-year-old male patient was admitted to our intensive care unit with sepsis due to bacterial pneumonia. Despite the use of air cushions and regular position changes, skin ulcerations occurred over his occiput, back, buttock, elbow, and ankle. After improvement in his general condition, he was transferred to the department of plastic and reconstructive surgery. Debridement was performed immediately, followed by conservative treatment (including a vacuum-assisted closure device) for 6 weeks. The buttock and occiput wounds were treated surgically. Despite complete healing, his caregivers sued the hospital for failing to prevent PU formation. ASF is a pressure-related injury resulting from hemodynamic instability due to organ system failure. Unlike PU, ASF may occur despite the implementation of all appropriate preventive measures. Furthermore, misdiagnosis of ASF as PU can lead to litigation. Therefore, it is critical for the proper diagnosis to be made quickly, and for physicians to explain that ASF occurs despite proper preventative treatment.

Collagen peptide plays a protective role in skin by increasing the activity of antioxidant, acts like an activator of skin regeneration by positive feedback and is used as a potent candidate for cosmetics or functional food. GABA acts at inhibitory synapses in the brain by binding to specific transmembrane receptors of both pre- and postsynaptic neuronal processes in vertebrates, is also involved in the synthesis of melatonin and might exert regulatory effects on sleep and reproductive functions. In this study, we investigated the beneficial effect of a mixture of collagen peptide and GABA (J85091900) on skin and sleep condition in woman experiencing sleep disorder. We found that oral supplement with J85091900 significantly decreased the value of Pittsburgh Sleep Quality Index (PSQI), increased sleeping time by 7%, and also improved skin roughness (Ra, Rz, Rt), periorbital wrinkle (Ra, Rt), and skin capacitance in human. These findings indicate that dual strategy with which skin improvement is accomplished using collagen peptide and sleeping well is acquired using GABA could be the novel solution for sleeping beauty by edible cosmetics to improve skin status.

Recently, auger-drilled piling has been widely used in urban area to reduce the air pollution and noise. But this construction method that its basic theory was introduced from Japan may be changed depending on the each piling company and construction field condition. Therefore, the design code and management method for auger-drilled piling is not defined yet. Especially, the lack of research on the bearing capacity of auger-drilled piling leads to the absence of rational bearing capacity prediction equation. This paper presents the optimum design code and economical construction method of the auger-drilled piling by proposing the new bearing capacity prediction equation based on the site specific soil types and construction conditions. In this paper, existing bearing capacity prediction equations and current pile load tests were compared. And the end bearing capacity and skin friction characteristics were also analyzed by comparing the results of CAPWAP. From the results of analysis, a reliable bearing capacity prediction equation considered soil types is proposed.

This study aimed to comparatively analyze changes in skin conditions according to the frequency of sheet mask use among women in their 60s. An experiment was performed for 5 weeks from May 1 to June 3, 2020. A total of 70 women in their 60s, who understood the purposes of this study and agreed to the experiment were selected. All empirical analyses were conducted at a significance level of 5%, and the SPSS WIN 21 program was used to perform statistical analysis. Increased moisture content, decreased coarseness, changes in sebum levels, and decreased pigmentation, were significant effects of sheet mask use for 7days per week. As long as the sheet mask did not irritate the skin, had a positive effects on the skin the more often it was used. These results can help in enhancing the effectiveness of systematic measurement and improvement of skin type. To determine factors affecting skin conditions, it is necessary to investigate and compare factors such as effects of dietary or living habits, genetic influence, and living environments.

This study was investigated the clothing microclimate, subjective sensation for the improvement of traditional koran high school student uniform so called "Saenghwal Hanbok". For the purpose, casual hanbok school summer uniforms were made. They were made of 4 different textiles materials - P/R, P100, P/C, P/R/S for blouses, P/W, P100, P/R, P/W/F for skirts. Then their clothing microclimate, subjective sensation were tested at room temperature $25{\pm}1^{\circ}C$ and $50{\pm}10%$ R.H. Clothing Microclimates wearing on the blouses were good matched comfort temperature range. Subjective sensations wearing on the blouses were better than those of traditional koran clothes so called "Hanbok" and quite same for western style clothes. Thermal sensations were indicated some hot condition, and moisture sensations were indicated some wet condition but tactile sensations and comfortable sensations were agreeable. The temperatures of the forehead and the breast wearing on the skirts were indicated the same results with the cases of the blouses. Leg temperatures were some lower than the mean skin temperature, the other parts' temperatures were slightly higher than blouses but the mean skin temperatures were satisfied comfortable ranges. Subjective sensations wearing on the skirts were better than those of the other traditional clothes and even Western clothes. Thermal sensations and moisture sensations were resulted the same with the case of blouses. Currently, P/R material and P/W material seemed to be cool and respectively suitable for blouses and skirts in summer among the materials of modernized Korean traditional costumes and school uniforms, since those materials lowered skin temperature. But better, physiologically pleasant materials for summer clothes should be development in consideration of clothing microclimate and subjective sensation.

TIn this paper, we find the face in color images and the ability to track the face was implemented. Face tracking is the work to find face regions in the image using the functions of the computer system and this function is a necessary for the robot. But such as extracting skin color in the image face tracking can not be performed. Because face in image varies according to the condition such as light conditions, facial expressions condition. In this paper, we use the skin color pixel extraction function added lighting compensation function and the entire processing system was implemented, include performing finding the features of eyes, nose, mouth are confirmed as face. Lighting compensation function is a adjusted sine function and although the result is not suitable for human vision, the function showed about 4% improvement. Face features are detected by amplifying, reducing the value and make a comparison between the represented image. The eye and nose position, lips are detected. Face tracking efficiency was good.

Elasticity and softness of the skin depend on the level of moisture present in the stratum corneum, which is known to be affected by various environmental changes, such as cold and hot winds and dry environments. However, not many studies have been conducted on changes in skin moisture and the degree of recovery due to individual skin differences. In the present study, we aimed to investigate the effect of warm air heating on skin hydration levels and develop moisturizing formulas to improve lowered skin hydration levels. In order to deliver warm air heating condition, heating dryer (40 ℃, 6 m/s, 30 cm apart from forearm) was applied into inner forearm of healthy subjects (male: 10, female: 39, age: 25 - 63) Among 49 subjects, 26 subjects showed significantly lowered skin hydration levels until 30 min after warm air heating exposure (lowered group). In addition, moisturizing cream with high water holding capacity was applied to forearm of 10 subjects in lowered group for 3 weeks and skin hydration levels after warm air heating were significantly improved at the levels of before application of warm air heating. From this study, we found out that there is a skin type that skin hydration levels are significantly decreased under warm air heating condition (dehydrated skin) and this dehydrated skin can be improved by moisturizing formulas with high water holding capacity.

To clarify the necessity of surgery for fistula-in-ano (FIA) in infant, a retrospective analysis of 82 cases FIA in infant were performed for 11 years period from 1987 to 1998. Group A included 44 cases in the period of surgery oriented treatment to 1992, and group B contained 38, period of feeding control oriented management (FC) after 1993. FC, that was indicated in case with loose stool and eczematoid perianal skin (LSES), composed of quit breast feeding, change of cow milk or complete weaning. Surgical decision was made after improvement of stool condition. Fistulectomy was performed in 29 cases (65.9 %) of group A. However, in group B, only 15 cases (39.5 %) required surgery (p=0.0036). Thirty-four cases in B had the history of LSES, and Fe was applied in 25, and was effective in 24. Among 24 cases, 21 showed complete healing with FC, 3 had surgery because of the persistent FIA, and 1 got operation due to no improvement of stool condition. In conclusion, Fe has to be applied to FIA in infant before surgery, particularly in cases with history of LSES. As one of the etiologic factors for FIA, LSES could be considered to this particular age group.
