Recently, nail industry trends have been shifting from polish nail to gel nail. Because of the popularity of gel nail, the criteria for customers to choose colors have significantly changed. Therefore, there has been a rising demand for a nail color which goes well with skin color, not with the color of clothes, makes the hand more beautiful. Unlike a face, hand skin color isn’t corrected through makeup. Therefore, it is more difficult to find a color which is well matched with the skin tone. In this sense, the accurate analysis and classification of hand skin color which is the first step in the selection of nail color are required. However, it’s still very hard to find studies on hand skin color. To figure out the characteristics of Koreans’ hand skin color by age, this study analyzed differences in hand skin color by age after measuring the tone of the back of the hand and conducting quantitative analysis against 300 women living in Busan, Ulsan and Gyeongnam. The results revealed statistically significant difference (p.001). As the respondents were younger, a bright skin tone was observed. According to analysis on the distribution by the rank, ‘20s’ was the highest with 46% among those with a bright skin tone within top 100 ranks. In top 300 ranks, in contrast, ‘50s’ was the highest with 46% while ‘20s (8%)’ was the lowest. In terms of a skin tone, there was a considerable difference between ‘20s’ and ‘50s.’ Even though no big difference was found between ‘30s’ and ‘40s,’ a skin tone was brighter in the latter.

The occurrence and time course of capacitation, acrosomal loss, and hyperactivated motility require quantitative definition in order to characterize fertile human sperm. Recently the method has been developed to estimate the quality of spermatozoa by using kinematic parameters such as curvilinear velocity(VCL), average path velocity(VAP), linearity(LIN), straightness(STR), amplitude of lateral head displacement(ALH), and beat cross frequence(BCF) from Computer Assisted Sperm Analysis (CASA). In this study, using the Hamilton Thorn motility analyzer HTM 2030(Hamilton Thorn Research, Beverly, MA), we attempted to identify the spermatozoa with hyperactivated motility (HA) objectively and to monitor hyperactivation of human spermatozoa during incubation in capacitating media and after treatment of calcium ionophore as compared with acrosome status. And we examined whether HA are related to the result of SPA. Semen samples obtained from 16 healthy men were prepared by swim up technique and preincubated in a capacitating media(modified BWW medium) for 5 hours and treated with calcium ionophore solution. The acrosome reaction was detected with PSA-FITC labelling of the acrosome and in vitro sperm ferilizing capacity was assessed by the zona free hamster ovum penetration assay (SPA). The incidence of hyperactivated sperm was 2.6% in fresh semen, 14.3% of the swim up population, 13.7% after 5h of incubation. Significant increase of percentage of hyperactivated sperm was observed after the incubation (p<0.05) but after treatment, no significant changes of percentage of hyperactivated sperm(l1.8%) in contrast to significant rise in the percentage of acrosome reacted cells. Correlation analysis failed to show any significant relationship between the percentage of sperm with HA and SPA score. In conclusion, although no direct correlations were found between the results of SPA and HA, hyperactivation of sperm is associated with capacitation and monitoring hyperactivated sperm will be expected as a method of evaluating the functional quality of sperm such as SPA.

Purpose: This study was conducted to corroborate factors affecting dental technicians recognition states of their job consciousness. Methods: Self-administering questionnaires were distributed directly to some 200 registered female dental technicians in metropolis, small & medium-sized cities, farming and fishing villages of whom 153(76.5%) female dental technicians and female students responded in December, 2009. Information on recognition states of female dental technicians and female students in department of dental technology possible occupational mind and other general characteristics was gathered. Analysis of data was processed by use of X2-test and multiple regression analysis. Results: The recognition states of occupational satisfaction were higher in female students than female dental technicians(p<.05). They were observed that between respondents with more than five years of work and less than five years of career(p<.05). Statistically significant differences were observed in recognition values of female dental technicians occupational satisfaction between high and low groups of internal characteristic of their position and all ceramic part(p<.05). Conclusion: For woman dental technicians, the most predictive variables for recognition values of occupational satisfaction were an age, between groups, which of part and career(p<.05). Finally, this result suggests the facts that in order to achieve self-realization through the work experience, women herself should get rid of the dichotomous diagram and should change the consciousness of traditional role normals.

This study was investigated the contents of total polyphenol, flavonoids and antioxidant and antimicrobial activities of Codonopsis lanceolata extracts according to different steaming times. The contents of total polyphenol and flavonoid proportionally increased from 6.45 mgGAE/g to 18.26 mgGAE/g and 2.01 mgRE/g to 6.12 mgRE/g according to ethanol extracts at EDS7. DPPH radical scavenging activity was found to have been 15.26~65.2% and showed the highest level of antioxidant activity at EDS7 was 65.2%. The activity of ABTS radical scavenging and SOD-like activity were also the same result. DPPH and ABTS radical scavenging activity was related to the number of steaming, and the scavenging activity was increased up to 7 times of steaming. The antimicrobial activity of EDS7 had strong antioxidant activity. Antimicrobial activities were examined against 5 microorganisms related to pathogens and food poisoning. The antimicrobial Activity was different depending on the bacteria, but it was effective at the concentration of 300 mg/mL rather than 150 mg/mL. These results showed that Codonopsis lanceolata extracts with a different number of steaming would be conducted to confirm the possibility of developing antimicrobial and antioxidant. It will be helpful in the study of component analysis of Codonopsis lanceolata extracts processed products.

이희경 ( Hee Kyung Lee ) 영유아교육학회 2011 영유아교육연구 Vol.14 No.-

본 연구의 목적은 유아교육과 학생이 유치원현장실습과 보육실습 기간에 경험한 교사의 역할에 어떠한 차이가 있는지 알아보는 것이다. 이를 위해 보육실습을 마친 2학년 학생110명과 교육실습을 마친 3학년 학생103명이 이희경 김성수(2000)의 ``유아교사 역할 Q-set``의 문항에 응답한 결과를 분석하였다 그 결과 보육실습생이 교육실습생보다 보육 및 기본생활지도에 비중을 두고 있으며 교육실습생이 보육실습생보다 관련 역할에 비중을 두는 것으로 나타났다. 또한 교육 및 교수학습활동 상담 및 정서적 지원 연구 및 반성적 실천 역할에는 두 집단 간에 차이가 나지 않았다. 연구 결과는 유아교육과 학생이 실습 및 취업을 위해 교사의 역할을 예견할 수 있는 기초 자료가 될 수 있다. The purpose of this study is to find out the differences of student teachers`` perceptions on the teachers role in kindergartens and daycare centers during student teaching practice. For this purpose, 110 students who experienced teaching practice in kindergartens and 103 students in daycare centers for 4 weeks were sampled. The data were collected by the questionnaire which was partially modified from Lee & Kim`s Early Childhood Teacher`s Role Q-set (2000). The findings revealed that the students who taught in daycare centers emphasized more on the role of nursing and teaching basic life habits than the students who taught in kindergartens did. However, on the role of teacher-parents relationships, community activities, and so on, the students who taught in kindergartens showed higher perception than the students who taught in daycare centers did. These findings help to predict the role and behavior of teachers during their practice teaching and employment.

This study was to investigate the extraction yield, total polyphenolics and flavonoid contents, radical scavenging activity, and acetylcholinesterase inhibitory activity of various extracts from Salicornia bigelovii. The extraction yields of hot water, ethanol, acetone, ethylacetate, and hexane were 18.8%, 15.4%, 2.6%, 13.3%, and 3.2%, respectively. The total polyphenolics and flavonoid contents in hot water extract (HWE) and ethanol extract (EE) were significantly higher than in acetone (AE), ethylacetate (EAE), and hexane extracts (HE). The total polyphenol and flavonoid contents were highest in EE (0.89% and 0.39%), followed by HWE (0.76% and 0.25%), AE (0.45% and 0.18%), EAE (0.36% and 0.14%) and HE (0.28% and 0.11%). ABTS radical scavenging activities in 10㎎/L of extracts were in the following order: EE (48.97%)> HWE (18.92%)> AE (14.32%)> EAE (12.50%)> HE (10.37%). In addition, the acetylcholinesterase inhibitory activity was observed in the same tendency as seen with the ABTS radical scavenging activity. These results suggest that the ethanol and hot water extracts from S. bigelovii may be used to develop various functional food and cosmetic products.

본 연구는 우리나라 누리과정이 도입되면서 유치원 교사양성교육에 요구되는 교사교육의 전문성제고 방안을 제시하는 것을 목적으로 한다. 이에 유치원교사의 국가 자격기준을 검토하고 전문대학과 4년제 대학의 유치원교사 양성 및 양성교육과정 현황을 분석하여 유치원 교사의 전문성제고 방안을 제시하였다. 교사 양성현황은 양성대학 유형과 입학정원, 졸업자 및 취업률, 수업연한, 자격증 발급수. 전문대학 전공심화과정 운영 현황 등을 분석해 제시 했으며, 양성교육과정현황은 교사자격 과목의 이수기준에 비추어 전문대학과 4년제 대학의 교육과정 편성현황을 분석해 제시했다. 유치원 교사의 전문성 제고 방안으로 첫째, 유치원교사 양성교육과정은 교사자격기준을 강화한 표준화 기반의 4년제 학사 과정으로 제고되어야 하며, 둘째, 유치원교사 양성기관은 누리과정 운영에 충실한 교원을 양성해야 한다. 향후 순차적인 전문대학 수업연한의 조정이 요구되며 누리과정 기반의 양성교육과정 운영이 요구된다. This study aims to present the way of enhancing kindergarten teacher`s professionalism through pre-service teacher`s education. For this, as the study method, the legal qualification criteria of kindergarten teachers were investigated, and the systems of kindergarten teacher education currently for teacher education curriculums of junior colleges that have 2~3 year courses and universities that have 4 year courses were analyzed. The results of the study are as follows. Firstly, all curriculums for pre-service kindergarten teacher education need to be a 4 year bachelor`s degree based on the tightening of teacher qualification criteria recently. Secondly, all the institutions for kindergarten teachers should educate the students according to the Nuri curriculum, so that after graduation they can implement the Nuri curriculum efficiently. Consequently, the years required for graduation of junior colleges needs to be extended to 4 year courses gradually, and the curriculum of the courses should be implemented focusing on the Nuri curriculum.
