Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

Background: Micro-needle patches have been recently used to increase skin permeability, which improves drug delivery, and for cosmetic purposes. However, these patches may of-ten have limited efficacy due to insufficient skin penetration and reduced compliance caused by discomfort. Objective: We evaluated the efficacy and the safety of soluble micro-spi-cule containing epidermal growth factor (MS-EGF) for the treatment of periocular wrinkles. Methods: Twenty healthy volunteers aged 33 to 54 years were enrolled in a random-ized, controlled, split-face study. For 4 weeks, a periocular wrinkle was treated daily with either a soluble MS-EGF cream or a cream containing EGF alone. All subjects under-went 8 weeks of follow-up. Efficacy was assessed using an ul-trasonic measurement of dermal depth and density, digital skin image analysis, 5-point photonumeric scale for peri-ocular wrinkles and subjective satisfaction. Results: MS-EGF group showed statistically significant increase of dermal depth and density compared to EGF alone group after 4 and 8 weeks. In addition, there was a marked improvement shown in clinical and 3-dimensional skin image in MS-EGF group. The treatments were well-tolerated; no significant side-effect was noted. Conclusion: The MS-EGF formulation may represent an effective and biocompatible advance in the treatment of periocular wrinkles. (Ann Dermatol 29(2) 187∼ 193, 2017)

Background: Microneedle patch recently have been used to increase skin permeability improving drug delivery and for cosmetic purposes. However, such treatment may fail if skin penetration is insufficient reducing drug delivery or if compliance is reduced by discomfort.Objectives: : To evaluate the efficacy and the safety of microspicules containing epidermal growth factor (MS-EGF) used to treat periorbital wrinkles. Methods: Twenty health volunteers were enrolled in a randomized, controlled, split-face study. One periorbital area was treated daily with soluble MS-EGF and the other with EGF cream, for 4 weeks; all subjects underwent 8 weeks of follow-up. Efficacy was assessed using a wrinkle severity rating scale (WSRS), subjective satisfaction scores, digital skin image analysis, examination of skin replicas, and ultrasonic measurement of dermal depth and density. Results: Both the MS-EGF and EGF alone yielded positive effects on digital skin image analysis, skin replica examination, and ultrasound. However, the MS-EGF groupexhibited significant improvements in dermal depth and density, and on replica analysis, compared to theEGF-only group (P < 0.05). In addition, the MS-EGF group showed a significantly greater change in WSRS score compared to baseline than the EGF-alone group. Both treatments were well-tolerated; no significant side-effect was noted. Conclusion: The MS-EGF formulation may represent an effective and biocompatible advance in the treatment of periorbital wrinkles.

Fabrication of Ni-Mo-based Electrocatalysts by Modified Zn Phosphating for Hydrogen Evolution Reaction

Im, Han Seo,Park, Seon Ha,Ha, Hyo Jeong,Lee, Sumin,Heo, Sungjun,Im, Sang Won,Nam, Ki Tae,Lim, Sung Yul The Korean Electrochemical Society 2022 Journal of electrochemical science and technology Vol.13 No.1

The preparation of low-cost, simple, and scalable electrodes is crucial for the commercialization of water electrolyzers for H₂ production. Herein, we demonstrate the fabrication of cathodes through Mo-modified Zn phosphating of Ni foam (NiF) for water electrolysis, which has been largely utilized in surface coating industry. In situ growth of electrocatalytically active layers in the hydrogen evolution reaction (HER) was occurred after 1 min of phosphating to form ZnNiMoP_i, and subsequent thermal treatment and electrochemical activation resulted in the formation of ZnNiMoPO_xH_y. ZnNiMoPO_xH_y exhibited superior HER performance than NiF, primarily because of the increased electrochemically active surface area of ZnNiMoPO_xH_y compared to that of bare NiF. Although further investigations to improve the intrinsic electrochemical activity toward the HER and detailed mechanistic studies are required, these results suggest that phosphating is a promising coating method and will possibly advance the fabrication procedure of electrodes for water electrolyzers with better practical applications.
