김인영 한국응용과학기술학회 2020 한국응용과학기술학회지 Vol.37 No.6

This study is about the UV protection effect and water resistance of a multiple emulsion (W/O/W) sunblock cream applied with emotional engineering and reports an actual industrial case. Multiple emulsion system of sunblock cream has the characteristics of changing to a W/O type that is soft and moist when applied, and has excellent water resistance after absorption. Multiple emulsion cream is a highly functional sunblock cream that has both moisture and water resistance. It is a stable milky white cream with a viscosity of 36,000 cps. The organic sunscreen used for the sunscreen was ethylhexylmethoxycinnamate and bisethylhexyloxyphenolmethoxyphenyltriazine. Hexagonal zinc oxide and titanium dioxide that block both UVB and UVA were used. As a result of measuring the UV protection effect by the in-vitro method, the UV protection effect (SPF) is 78.9 for multiple emulsion cream, 76.7 for W/O cream, and 71.3 for O/W cream. It was found that the blocking effect was different. This obtained the highest effect value in the multiple emulsion. As a clinical (in-vivo) result of the UV protection effect, the SPF value representing the UV protection effect of the sunblock cream developed with a multiple emulsion system was 85.7, and the PA-value that blocks the UVA area was 26.5, and ++++. It was found that it has a corresponding high blocking effect. As a result of the water resistance test, the W/O/W formulation had a high waterproofing resistance of 93.8% even after 4 hours, W/O had 75.4%, and O/W had a low water resistance of 25.3%. In the results of the HUT test, it was found in the order of multiple emulsion sun block cream > hydrophilic cream > lipophilic cream. Based on the research results of this multiple emulsion, it is expected to be highly active as a sunblock cream dedicated to outdoor activities by improving the feeling of use, UV protection index, and water resistance. Therefore, in this study, a multiple emulsion system of sunblock cream is developed and has a characteristic that changes to a W/O type that has a soft and moist feeling when applied, and has excellent water resistance after absorption.

The purpose of the study is to examine the relationship between teacher enthusiasm, support for teacher autonomy, support for relationship with peers, and grit for preliminary high school students. This will be able to provide useful information for effective instruction and search for various teaching-learning methods in the physical education field. It was selected based on convenience sampling and judgmental sampling, focusing on those who participate in physical education classes for middle school students. Of the 200 respondents to the questionnaire, the study was conducted through 182 copies, excluding 18 questionnaires that were judged to be unreliable or responded collectively. When looking at the effects of physical education teachers' passion on autonomy support and relationship support, the hypothesis was adopted as it was found to have a statistically significant effect. Relationship support appeared to have a statistically significant effect on grit, so the hypothesis was adopted. However, support for autonomy was rejected as it did not appear to have a statistically significant effect on grit.

Inclusion complex formation of octyldimethyl p-aminobenzoate with ${\beta}-cyclodextrin$in aqueous solution and in the solid state was studied by the solubility method, spectroscopic (UV, FT-IR) and X-ray diffractornetry. The solid complex of octyldimethyl p-aminobenzoate with ${\beta}-cyclodextrin$ was obtained in molar ratio of 1:2 (guest/host). A spatial relationship between host and guest molecule was clearly reflected in the magnitude of the apparent stability constant (K') and in the stoichiometry of the inclusion complex. Furthermore, a typical type Bs phase-solubility diagram was obtained for octyldimethyl p-aminobenzoate and ${\beta}-cyclodextrin$ in water at $25^{\circ}C$. The results indicated that the solubility of the guest molecule was higher by the formation of ${\beta}-cyclodextrin$ inclusion complex.

김대용 한국응용과학기술학회 2020 한국응용과학기술학회지 Vol.37 No.6

This study is aimed at determining whether graviola (Annona muricata) beneficially influences immunoglobulin (Ig) E-mediated allergic reactions in human mast cells (LUVA cells). To examine the anti-allergic effect of graviola leaf extract (GLE), we treated antigen/IgE sensitized mast cells with extracts of various concentrations. In this study, the results of the in vitro model of IgE-mediated mast cell degranulation showed that GLE significantly inhibited the release of histamine, β-hexosaminidase, TNF-α, IL-4 and IL-6 in LUVA cells. Pretreatment with GLE suppressed the phosphorylation of antigen-induced Lyn and Syk, thus suppressing the downstream MAPK pathways. The above results indicate GLE could suppress mast cell activation and allergic responses. Accordingly, it can be supported that GLE has the potential to be used as functional cosmetic material.

생활체육과 스포츠복지 정책 전달체계 : 정책 효과성 증대를 위한 거버넌스의 가능성 탐색

김한범(Hanbeom Kim),이장원(Jangwon Lee) 한국응용과학기술학회 (구.한국유화학회) 2021 한국응용과학기술학회지 Vol.38 No.1

생활체육 정책은 스포츠복지 정책의 개념적 범주에서 다루어질 필요가 있다. 스포츠복지의 개념을 넘어서 일반적인 복지의 중요한 부분으로 인식될 수 있어야 스포츠복지 정책이 가지는 효과성을 더욱 증대시킬 수 있다. 그리고 대상자인 국민에게 스포츠복지 정책을 효과적으로 전달하기 하기 위해서는 스포츠복지 정책이 다른 복지 서비스와 마찬가지로 국가적 차원의 전달체계 안에 편입될 필요가 있다. 본 연구에서는 스포츠복지 정책이 국가적 차원의 전달체계에 편입되는 방안 중 하나로 스포츠복지 거버넌스의 구성과 이를 총괄할 수 있는 스포츠복지 조직을 신설하는 복지전담 독립형 정책 모델을 제안하였다. In order for life-sports to develop sports policies need to be addressed in the conceptual categories of sports welfare policies. Beyond the concept of sports welfare;it must be recognized as an important part of general welfare to further increase the effectiveness of sports welfare policies. And for sports welfare policies to be effectively delivered to the target people;it need to be incorporated into a national-level policy system such as a general welfare system. In this study sports welfare governance and Exclusive Organization Policy Model was proposed as one of the ways in which sports welfare policies were incorporated into a national delivery system.
