        This study is to observe the effect of Artemisia herb on the mitigation of hair damage when performing permanent wave by classifying general treatment (N) and Artemisia treatment (A) after performing permanent wave by varying the processing time. the findings are as follows after observing the hair thickness, tensile strength, elongation and undamaged hair. As a result, the treatment group A2 which Artemisia herb extract was added showed 0.0422 ± 0.0017 ㎜ which is the thickest among the control group and normal hair. The result of tensile strength showed A2>A1>C>N1>N2 in sequence. Among them, Artemisia herb added group A2 was 141.03 ± 21.91 ㎜ which increased by 32.91% compared to that of the control group C, showing the highest among the experiment groups. In the case of measuring the elongation, general treatment N1 was 163.82 ± 17.14%, preprocessing operation was high. In the case of Artemisia herb treatment, A2 was 148.13 ± 27.89%, postprocessing operation was high. As a result of observing normal hair, cuticle of group c was overall excited with crack, showing the largest damage among all experiment groups. The result of preprocessing experiment group AP of Artemisia herb treatment (A) has regular scale and became smooth due to minimized cuticle swelling. In the case of post processed AA has clear and regular cuticle arrangement and the damage area such as abrasion, peeling was decreased.

      • 어린이 교육용 모바일 어플리케이션에 대한 비교연구

        김진란(Kim, Jinran) 한국디자인지식학회 2015 디자인지식저널 Vol.33 No.-

        최근에는 스마트폰을 이용해 어린이들을 교육하는 모습을 쉽게 찾아 볼 수 있으며, 많은 기업과 회사들은 교육용 모바일 어플리케이션 개발에 힘쓰고 있다. 많은 교육용모바일 어플리케이션이 생겼고 생겨나고 있지만 개발자들에게는 가이드라인이 존재하지 않는다. 따라서 본 연구는 기존의 교육용 모바일 어플리케이션을 비교분석해 교육용모바일 어플리케이션에 필요한 요소들이 어떠한 것이 있는지 알아보고자 했다. 이 때 비교분석을 위해 어린이 디자인 가이드라인을 모바일 어플리케이션에 맞춰 수정해 적용하였다. 또한 실험에 참여한 초등학교 1, 2학년생들을 인터뷰하였다. 본 연구결과, 한 교육용 모바일 어플리케이션은 고루 높은 점수를 얻었고 인터뷰 결과에서도 좋은 평가를 받았지만, 또 다른 모바일 어플리케이션은 점수가 고르지 않았으며 인터뷰에서도 아쉬움을 남는 결과를 얻었다. 이러한 결과를 종합해 교육용 모바일 어플리케이션의 중요 요소들은 유추해낸 결과, 모든 모바일 어플리케이션이 그러하듯 사용자 혹은 구매자의 흥미를 유발시킬 수 있어야하는데, 어린이 교육용 모바일 어플리케이션의 경우 게임의 다양성과 일러스트 등을 통해 흥미를 유발시킬 수 있음을 알아냈다. Nowadays, children use educational mobile applications for their study. Also many companies make educational mobile applications. However, developers do not have guideline. Accordingly, the purpose of the study is to compare the contents in the current educational mobile applications and find out the factors to complement the contents. Reacher use children design guideline that modify and change suitable for children"s educational mobile applications. Also, researcher did interview elementary school students who participate in this study. Research result, other children"s educational mobile applications get high score and good evaluation at the interview. But, another children"s educational mobile applications get low score and negative evaluation at the interview. When all the studies were combined, in this case, children"s educational mobile application should arouse user’s interest, various game and illustration.

      • 애엽 열수추출물의 생리활성에 관한 연구

        In this study, in order to explore whether hair damage by activated oxygen being generated during chemical treatment of hair could be prevented in advance, Artemisiae argi Folium having excellent anti-oxidant effect as a natural substance containing tiny amount of amino acid was used. Hereupon, antioxidant activity, anti-inflammatory, and cytotoxicity of Artemisia herb extract were measured. Evaluation was made as follows deriving a conclusion. In DPPH radical scavenging activity based on concentration of 0.2 mg/ml, its activity over 90% equivalent to that of Vit C that is control group was represented. In ABTS scavenging activity based on concentration of 1 mg/ml, a result lower than positive control group was shown but scavenging activity was increased along with increased concentration. Contents of polyphenol and flavonoid was 449.357+/-34.699 μg/㎖and 2.65+/-0.057 μg/ ㎖, respectively. As a result of measuring survival rate by using Raw 264.7 cell in order to determine cytotoxicity status of Artemisiae argi Folium extract, toxicity was not evident in low concentration of such extract. According to aforementioned results, it was confirmed that there was a high chance of availability as hair care cosmetics because of antioxidant effect, cytotoxicity, and anti-bacterial effect of Artemisia herb extract.
