The purpose of the present study is to develop a scale to measure ecoliteracy in Korean young children and evaluate its validity and reliability. To examine the validity and reliability of the ecoliteracy scale for young children, statistical analyses were performed utilizing data from a main survey. SPSS 23.0 and AMOS 22.0 statistical software were used to carry out the exploratory and confirmatory factor analysis of the research variables, including the means of response values, standard deviations, frequencies, and percentages. In addition, analysis of internal consistency reliability and Pearson’ correlations was performed concerning the questions that comprised the research variables. Furthermore, descriptive statistics of the research variables were proposed and normality was examined. The final number of items contained in the scale was 50, including five reverse score questions. Items were measured using a 5-point Likert scale. The ecoliteracy scale for young children was applied to 1,249 young children, whose ages were between four and five years, attending 73 institutions in Seoul, Gyeonggi Province, Chungcheong Province, Jeolla Province, Gyeongsang Province, and Gangwon Province. Results revealed that all items met the statistical standards. The process of verifying construct validity of the scale by confirmatory factor analysis gathered all the 50 items that met statistical standards and eight primary factors/subcategories were extracted through exploratory factor analysis. The scale consisted of six items related to the “rights of nature,” five items for “intent of support,” eight items for “care about resources,” eight items for “ecological sensitivity,” five items for “ecological social relationships,” six items for “eco-development,” six items for “domination of nature,” and six items for “apathy towards eco-crisis.” R² of the final scale was 77.0%, and Cronbach’s α reliability coefficient was .788. 본 연구의 목적은 유아의 생태소양을 측정하기 위한 척도를 개발하는 것이다. 이를 위해 SPSS 23.0, AMOS 22.0 통계프로그램을 활용하여 전 문항 응답 값의 평균, 표준편차, 빈도, 백분율을 구하였고, 연구변수로서 요인을 구성하는 탐색적 요인분석과 확인적 요인분석을 시행하였다. 더불어 연구변수를 구성하는 문항 간 신뢰도 분석을 하였다. 또한, 연구변수의 기술 통계량을 제시하고 정규성을 검토하였다. 유아 생태소양척도의 개발 단계에 최종 도출된 문항 개수는 전체 50문항이며, 그 중 5개의 역 문항으로 구성되었다. 척도의 측정 형태와 양식 구성은 성인 평정용, 5점 Likert 척도로 하였다. 서울, 경기, 충청, 전라, 경상, 강원 지역에 소재하고 있는 73개 유아교육기관에 재원 중인 만 4, 5세 유아 1,249명에게 유아 생태소양 측정 도구를 적용한 결과 모든 문항이 기준치에 적합하였다. 탐색적 요인분석으로 8개의 하위 요인을 추출하였고, 확인적 요인분석을 통해 도구의 구성타당도를 검증하는 과정에서 50개 문항 전체가 양호한 기준으로 도출되었다. 자연의 권리 6문항, 지원 의도 5문항, 자원 보호 8문항, 생태 감수성 8문항, 생태사회관계 5문항, 생태 개발 6문항, 자연 지배 6문항, 생태 위기 무관심 6문항으로 구성되었다. 최종 도구의 설명력은 77.0%, 신뢰도는 Cronbach’s α .788이었다.

Recently, as peoples’ interests in Well-being grow, their interests in developing natural, functional cosmeticingredients are also increasing. The research of Brown Seaweeds; an abundant resource around the world,is actively in progress. Fucoidan; which is contained in Brown Seaweeds, is a Polysaccharide containingSulfates. Fucoidan is found to have similar properties with Heparin; which is also in blood, but has a largeramount of Sulfates in comparison and is therefore proven to be more effective. The research on the effectsof Fucoidan for anti-inflammation, anti-tumors, antivirus, etc. is progressively moving forward. While theresearch regarding the functionality of Fucoidan in pharmaceuticals and foods is complete, the developmentof cosmetics using these ingredients is still premature. In this thesis, the research that has been done onthe effects of Fucoidan towards hydration, whitening and antioxidants has been reviewed. Also, the prospectof Fucoidan as a functional ingredient in cosmetics has been looked into. However, because the largemolecular weight of Fucoidan prevents it from being absorbed properly into the body and the technique toremove the distinct scent of the seaweed has yet to be completed, the value of Fucoidan has not been usedto its fullest potential. Therefore, aggressive research in these areas is necessary.

임진경,노은호 한국보육학회 2014 한국보육학회지 Vol.14 No.3

본 연구의 목적은 교육조력자로서의 어머니 기질 및 양육행동이 유아의 놀이성 발달에 미치는 효과에 대해 알아보는 것이다. 본 연구는 서울과 경기 지역에 소재하고 있는 13곳의 유치원 및 어린이집에 재원 중인 만 3, 4, 5세 유아와 어머니 171쌍을 대상으로 하였다. 분석결과 첫째, 어머니의 취업여부에 따른 유아 놀이성의 차이에서 취업모의 경우 유아 놀이성의 모든 하위요인이 유의미한 차이를 보였으며, 특히 사회적 자발성에서 두드러진 차이를 나타냈다. 그리고 유아의 놀이성은 어머니의 학력과 관계없이 평균 이상의 점수를 보였다. 둘째, 어머니의 기질, 양육행동과 유아의 놀이성 간의 상관관계를 살펴본 결과 어머니의 정서성 기질요인이 높을수록 유아의 놀이성 수준이 낮게 나타났으며, 활동성과 사회성이 높을수록 놀이성 수준이 높게 나타났다. 그리고 어머니의 온정·격려와 한계 설정의 양육행동 수준이 높을수록, 과보호·허용과 거부·방임의 양육행동 수준은 낮을수록 유아의 놀이성 정도가 높게 나타났다. 셋째, 어머니의 기질과 양육행동이 유아의 놀이성 전반에 영향을 미쳤으며, 특히 사회적 자발성에 기질은 25.0%, 양육행동은 18.2%으로 가장 높은 상대적 설명력을 나타냈으나 정서성 기질요인은 부정적으로 작용하였다. The purposes of this study were to understand influences of mothers’temperament and parenting behaviors as a Collaborator on their young children’s development of playfulness. Subjects were 171 couples of 3 to 5-year-old children and their mothers from 13 early childhood educational institutions in Seoul and Gyeonggi-Do. Main results of this study were as follows: First, the level of the young children’s playfulness of working mothers was high. Particularly, young children’s social spontaneity showed statistically meaningful differences. And playfulness of young children, regardless of the mother's education showed an above-average score. Second, high levels of mothers’activity and sociality were correlated to high levels of their children’s playfulness. Also, high levels of mothers’warmth-encouragement and limit-setting behaviors as well as low levels of overprotected-permissiveness and denial-neglectedness were related with high levels of young children’s playfulness. Third, mothers’temperament and parenting behaviors had influences on their young children’s playfulness. Especially, young children’s social spontaneity was highly influenced by their mothers’temperament and parenting behaviors. However, mothers’emotionality of temperament had negative influence on their young children’s social spontaneity.

This study investigates the effect of sensory exploration play based on a curriculum on the playfulness of infants. The study involved 22 one-year-old infants from daycare centers in Seoul, and 11 in the experimental group and 11 in the control group. The study was conducted between June and November 2022, with a total of 12 sensory exploration games conducted twice a month for the experimental group. The data were analyzed using mean and standard deviation, internal consistency coefficient, and independent sample t-test through the statistical program SPSS 25.0 Version. Results show that sensory exploration play based on a play-oriented curriculum had a significant effect on infants' playfulness, particularly in the sub-factors of social spontaneity, cognitive spontaneity, and enjoyment. These findings suggest that sensory exploration play based on a play-oriented curriculum is a meaningful activity for enhancing infants' playfulness.

In this study, we investigated the effect of hops extract on inhibition of tyrosinase activity and collagen production and MMP-1 expression in human fibroblasts using M-tyrosinase and C-tyrosinase, Cytotoxicity and collagen production and MMP-1 expression were measured. The results showed that M-tyrosinase and C-tyrosinase significantly inhibited the activity of tyrosinase. Cell viability and cytotoxicity of HDF cells showed cytotoxicity at the concentrations of 6.25, 12.5 and 25 μg/ml of hops extract I did. Inhibition of MMP-1 activity was found to be insignificant and the effect of collagen synthesis was increased in a concentration-dependent manner. However, ascorbic acid As a positive control group, it was confirmed that the hops extract did not significantly affect the collagen production. Therefore, the anti-aging effect of the hops extract is considered to be insignificant.
