Recently, when electric traction system used DC 1500[Vdc] runs on decline of rail road track and slows down, dc voltage goes beyond regular voltage. In this case extra power is forcibly wasted by resister because rectifier of substation and electric train including power convertor and so on are out of order. Therefore this paper proposes that the extra power is regenerated through regeneration inverter to AC utility in result this system obstruct to go beyond regular voltage and improve the efficiency. In addition, electric traction system products harmonic current and voltage distortion and reactive power because power converter is used so regeneration inverter normally runs such as active power filter(APF) for improving power quality.

스트론튬 루세네이트 (SrRuO₃)의 전극은 페로브스케이트 구조 유전체의 유전 특성을 향상시킬 수 있어 DRAM(Dynamic Random-Access Memory) 에 가장 적합한 전극 재료로 사용되고 있다. 이러한 장점들을 가지고 있는 스트론튬 루세네이트 (SrRuO₃) 박막이 투명 전극(Transparent Conductive Oxide; TCO) 으로의 사용 가능성을 확인해 보기 위해 연구하였다. 본 연구에서, 스트론튬 루세네이트(SrRuO₃) 박막을 유리 기판 위에 RF 마그네트론 스퍼터링 법으로 상온에서 증착 하였다. 박막의 두께에 따른 광학적 특성과 전기적 특성을 관찰하기 위하여 증착 시간을 5분과 50분으로 설정하여 실험을 진행하였다. 증착 시간이 증가할수록 박막 두께가 5nm에서 68nm로 증가하였고 광 투과율이 80%에서 40%로 감소하였다. 전기적 특성인 비저항은 박막 두께가 증가 하면서 1.99 mΩ·cm 에서 26.3 mΩ·cm 로 증가하였다. 결과적으로, 스트론튬 루세네이트(SrRuO₃) 박막을 유리 기판 위에 5분 증착 하였을 때, 약 80%이상의 투과율과 4.57eV의 밴드 갭, 그리고 1.99 mΩ·cm의 비저항을 보여주었다. The SrRuO₃ electrode can improve the dielectric properties of the perovskite structure. Thus, it is the most suitable electrode material for Dynamic Random-Access Memory (DRAM). This study was conducted to investigate the possibility of the SrRuO₃ thin film as a transparent conductive oxide (TCO). In this study, an SrRuO₃ thin film was deposited on the glass substrates by the RF magnetron sputtering method at room temperature. To observe the difference in optical and electrical properties as per the thin film thickness, the deposition times were set to 5 and 50 min. As the deposition time increased, the film thickness increased from 5 to 68 nm, the optical transmittance decreased from 80% to 40%, and the resistivity (an electrical property) increased from 1.99 to 26.3 mΩ·cm. Consequently, when the SrRuO₃ thin films were deposited on the glass substrates for 5 min, a transmittance of about 80% or more, a band gap of 4.57 eV, and a resistivity of 1.99 mΩ·cm were observed, thus verifying that an SrRuO₃ electrode can improve the dielectric properties of perovskite.

This study tried to survey which makeup image of females single males in their 20s and 30s living in Seoul and Daejon prefer in thedecision making to choose a female for love and marriage when they see the four different makeup images of females. Single malespreferred ‘Smoky makeup’ in the choice of a date of love and ‘Natural makeup’ in the choice of a mate in marriage most. Again malesin their 20s preferred ‘Smoky makeup’ most for their date of love, but those in their 30s preferred ‘Sexy makeup,’ whereas for a mate inmarriage males in their 20s preferred ‘Natural makeup’ and ‘Cutie makeup’ most while those in their 30s preferred ‘Natural makeup’ among the rest. Furthermore extroverts preferred ‘Sexy makeup’ wearers as a date of love and ‘Natural makeup’ wearers as a mate inmarriage. But introverts preferred ‘Natural makeup’ most in their selection of a date of love and a mate in marriage identically. There forethe analysis of the results from all the above experiments shows that in general when a single male picks a female date for love, heprefers a luxurious and urban image of ‘Smoky makeup’ and ‘Sexy makeup’ most whereas he prefers a pure and natural image of ‘Natural makeup’ among the rest in time of considering a mate in marriage.

연구논문 : 여대생의 외모관심도가 네일관리행동에 미치는 영향

방효진 ( Hyo Jin Bang ) 한국미용학회 2013 한국미용학회지 Vol.19 No.4

본 연구는 전라북도와 대전에 재학 중인 여대생을 대상으로 외모관심도와 네일관리행동을 조사한 연구로서, 외모관심도와 네일관리행동에 대한 요인구조 및 인과관계를 살펴보고자 하였다. 본 연구에서는 다음과 같은 결론이 도출되었다. 외모관심도와 네일관리행동의 평가를 바탕으로 요인분석을 실시한 결과, 외모관심도에서는 자기주도관심도, 패션관심도, 타인주도관심도 요인으로 추출되었으며, 이중 자기주도관심도 요인이 가장 중요한 평가요인으로 작용하였다. 네일관리행동 에서는 자기표현, 자기변화, 타인의식 요인으로 추출되었으며, 이중 자기표현 요인이 가장 중요한 평가요인으로 작용하였다. 즉 외모관심도와 네일관리행동은 그 유형에 따라 중요한 요인 이 각각 다르게 나타났다. 외모관심도에 따른 네일관리 필요성의 차이를 보았을 때, 자 기주도관심도, 패션관심도에서 차이를 나타냈으며, 이는 평소 자신의 외모관리에 관심이 많고 패션을 중요하게 인식할수록 네일관리가 매우 필요하다고 인식하였다. 또한 네일관리행동 에 따른 네일관리 필요성의 차이를 보았을 때, 자기표현, 자기 변화, 타인의식에서 차이를 나타냈는데, 이는 평소 손톱의 자기관리, 이미지 변화 추구, 상대방에 대한 시선의식을 중요하게 생각할수록 네일관리가 매우 필요하다고 인식하는 것을 알 수 있었다. 외모관심도와 네일관리행동 요인의 상호 관련성을 살펴보기 위해 상관관계분석을 실시한 결과, 자기주도관심도 요인은 네일관리행동의 자기표현, 자기변화 요인과 다소 높은 상관관 계를 보였다. 또한 패션관심도 요인은 네일관리행동의 타인의 식, 자기변화, 자기표현 요인과 다소 낮은 상관관계를 보였으며, 타인주도관심도는 네일관리행동의 타인의식과 다소 높은 상관관계를 나타내었다. 이러한 각 요인들 간의 상호 관련성을 바탕으로 외모관심도 에 따라 네일관리행동에 미치는 영향을 살펴 본 결과, 평소 자 신의 몸매관리, 외모개선 등의 자발적인 관리 성향이 높을수록 자신의 손과 손톱에 대한 관리행동에 영향을 미쳤으며, 또한 네일관리를 통해 자신의 손과 손톱이 변화되고 싶은 성향에도 높은 영향을 미치고 있었다. 외모관심도 중 자신의 패션과 스타일 연출에 관심이 높은 대상일수록 네일관리를 통해 자신의 손과 손톱을 변화시키려는 관리행동과 대인관계에서의시선 의식 및 예의를 중요시 하는 네일관리에 영향을 미치고 있었다. 외모관심도 중 타인에 의해 전문적인 메이크업 및 헤어 연출방법을 학습하는 외모관심 집단일수록 대인관계에서의 시선 의식 및 예의를 중요시하는 네일관리에 영향을 미쳤으나, 자신 이 손과 손톱을 관리하는 행동은 낮아지는 것을 알 수 있었다. 따라서 본 연구의 결과를 통해 여대생의 외모관심도와 네일 관리행동의 인과관계를 알 수 있었으며, 조사대상이 대학생에 국한됨에 따라 모든 연령의 여성을 대표하기엔 다소 제한점이 있었다. 향후 후속 연구에서는 좀 더 다양한 연령의 여성을 대 상으로 추가 조사한다면 네일관리에 대한 행동 변화에 대하여 더욱 심층적인 결과가 도출될 것으로 기대하는 바이다. As the result of factor analysis about appearance interest and nail management behaviors, one of the most crucial factors for the appearance interest is self-directed interests. In addition, self-expression affects the nail management behaviors the most. Based on these aspects, we have examined the differences between the necessity and perception of the nail management, and figured out that the appearance interest showed meaningful contrasts in the fashion and self-directed interests. For the nail management behaviors, there were significant differences in self-expression, self changes as well as the perception of others. With consideration for the relations between factors of the appearance interest and the nail management behaviors, the self-directed interests were highly related to the self-expression and the self-changes of the management behaviors. The aspects of self-directed interests had relatively high relevance to self-expression and self-changes of the nail management behaviors. Moreover, the fashion interest factors were less correlated with perception of other, self-changes and self-expression of the nail management behaviors, and also the other-person-directed interests have something to do with other person`s perception of the nail management behaviors. As we checked the nail management acts in accordance with the appearance interest, the higher people`s self-directed appearance management is, the more they manage their nails by themselves and they care their nails by considering others. In case that the subjects are greatly interested in fashion, they tend to manage their nails for varying their appearances and caring other people. As they pay attention in directing their images affected by others, they care their nails because of other people. On the contrary, they less manage their nails by themselves.

본 연구는 기업의 광고에 일러스트레이션을 활용함으로써 소비자의 시선을 유도할 수 있는 방안을 모색하는 것을 목적으로 한다. 연구방법은 소비자의 감성반응을 독립 변수로 설정하였고, 광고태도반응을 종속 변수로 설정하였다. 이에 감성 반응이 광고 태도 반응에 미치는 영향을 분석하기 위해 가설로 설정하였다. 강원도 소재의 대학생 278명을 대상으로 바디아트 일러스트레이션이 접목된 광고에 대한 감성반응이 광고태도반응에 미치는 영향을 분석하였다. 본 연구의 결론은 다음과 같다. 소비자의 감성 반응이 광고태도반응에 미치는 영향을 분석한 결과, 가설1은 장식성과 품위성이 흥미성에 영향을 미쳤으며, 가설2는 친숙성과 품위성이 신뢰성에 영향을 미쳤다. 즉, 광고의 바디아트 일러스트레이션이 장식적이고 품위 있는 감성을 느낄수록 광고를 흥미적으로 인식하는 태도가 상승하였으며, 소비자의 시각에 친근하고 품위 있는 감성으로 느낄수록 광고에 신뢰적인 태도로 나타남을 알 수 있었다. 가설3은 일러스트의 품위성과 매력성이 주목성에 영향을 미쳤으며, 가설4는 친숙성과 품위성이 신뢰성에 영향을 미쳤다. 즉, 광고의 바디아트 일러스트레이션이 품위적이고 매력적인 감성으로 느낄수록 광고가 더욱 주목되는 태도를 나타내었으며, 품위적이고 매력적인 감성이 낮게 느낄수록 광고가 선정적으로 인식되어 부정적인 태도가 상승함을 알 수 있었다. 결론적으로 향후 기업들이 광고 제작을 하는 과정에서 광고에 바디아트의 예술적인 일러스트레이션 요소를 접목함으로써 장식성, 품위성, 매력성, 친숙성을 적절히 강조할 수 있으며, 제품광고에 소비자가 시선을 주목하고, 흥미와 신뢰가 상승되는 효과를 줄 수 있음을 확인하였다. 향후 일러스트레이션을 접목한 제품광고를 통해 소비자의 관심도를 더욱 상승시킬 수 있다고 기대된다. The purpose of this study is to use the illustrations in product company advertisements to draw attention to consumer impressions of advertisements. In the research method, the emotional response of the consumer was set as an independent variable, and the advertising attitude response was set as a dependent variable. The hypothesis was set to analyze the effect of emotional responses on advertising attitude responses. For the research, 278 undergraduate students in a university in Gangwondo were investigated to analyze the effects of emotional responses to the body art illustrations in advertisements on their responses and attitudes to the advertisements. The results of the investigation were as follows. From an analysis of the effects of emotional responses of consumers on their responses and attitudes to the advertisement, Hypothesis 1 influenced the interest in decorativeness and dignity, and Hypothesis 2 influenced the reliability of familiarity and dignity. In other words, it was revealed that the more decorative and decorous impression consumers get from the body art design in an advertisement, the more they find the advertisement interesting. Also, the more the consumers find an advertisement decorous and friendly, the higher the level of reliability of the advertisement they feel. Hypothesis 3 has an illustration's dignity and attractiveness influenced attention, and Hypothesis 4's familiarity and dignity influenced reliability. In other words, the more the body design art in advertisement give a decorous and attractive impression, the more the consumers pay attention to the advertisement. Yet, the less the consumers feel decorous and attractive impression from a body art design in advertisements, the greater their negative attitude becomes against the advertisement, which is recognized to be too sexual. As a conclusion, the decorativeness, decorousness, attractiveness, and friendliness can be adequately moderated in the process of adding body art illustrations in the advertisement of product companies. From the process, It is expected that consumers can pay attention to product advertising and increase interest and trust. In the future, it is expected that consumers' interest can be further increased through product advertisement that incorporates illustrations.

방효진(Hyo-Jin Bang),차호연(Ho-Yeon Cha),김정희(Jeong-Hee Kim) 한국인체미용예술학회 2012 한국인체미용예술학회지 Vol.13 No.1

Modern makeup industry area has been extended and it is divided to beauty makeup and art makeup. The practice of makeup tends to be professionally subdivided. So I analyzed the characteristics of beauty makeup and art makeup by remark and awareness of experts group. The results were as follows.: The two makeup subdivisions are characterized by representing methods. The art makeup shows more important technique then beauty makeup. The Design is the most important representing factor to distinguish makeup. To analyze the representing characteristic of each subdivision, the color is the most important factor in beauty makeup and the design is the most important factor in art makeup. The result of submission of actual makeup image also shows the same result. According to the result of two independent subdivisions, there are some difference in ‘contrast’, ‘change’, ‘symmetry’, and ‘consistency’ and there are no difference in ‘harmony’and ‘gradation.’ In sensitivity evaluation, ‘familiarity’ and ‘purity’ are higher evaluation factor in beauty makeup and ‘ornamentation’ and ‘attractiveness’ are higher evaluation factor in art makeup. The design is the most distinguishable representing factor and the result of submission of actual makeup image is the same. In sensitivity evaluation, ‘familiarity’ and ‘purity’ are higher evaluation factor in beauty makeup and ‘ornamentation’ and ‘attractiveness’ are higher evaluation factor in art makeup. Therefore, there are contrary to each makeup subdivision in the sensitivity.

방효진(Hyo-Jin Bang) 한국콘텐츠학회 2016 한국콘텐츠학회논문지 Vol.16 No.12

경기도와 강원도 소재의 대학생 221명을 대상으로 컬러렌즈 착용 유무에 따른 이미지 효과를 알아보기 위한 연구로서 시각적으로 나타나는 평가요인을 살펴보았고, 평가요인에 따른 이미지 효과의 차이 및 관련성을 알아보았다. 또한 컬러렌즈의 착용이 여성의 눈과 얼굴 이미지 변화에 어떠한 효과가 있는지 규명하고자 하였다. 컬러렌즈 착용 이미지에 대한 감성평가는 화려함, 매력적, 세련됨, 호감도 등을 의미하는 항목이 높게 인지됐지만, 미착용 이미지는 편안함, 부드러움, 청순함 등을 의미하는 항목이 높게 인지되었다. 평가 항목에 대한 요인분석을 실시하였을 때, 컬러렌즈 착용 이미지는 매력성, 청아함, 친숙성, 장식성 순으로 분류되었고, 컬러렌즈의 미착용 이미지는 친숙성, 매력성, 청아함, 장식성 순으로 분류되었다. 컬러렌즈를 착용한 눈의 장식적, 매력적, 청아한 요인은 눈과 얼굴 이미지를 변화된다고 인지하였다. 컬러렌즈 착용 유무의 각 요인과 이미지 효과의 상관관계를 분석한 결과, 착용 이미지에서는 장식적, 청아함, 매력적으로 인식할수록 눈과 얼굴 이미지를 변화시키는데 관련성이 있는 것으로 나타났다. 즉 컬러렌즈의 착용은 눈과 얼굴의 이미지가 매력적, 청아함, 장식적으로 보이는 효과가 있었으며, 이러한 컬러렌즈 착용 효과는 자신의 개성에 맞도록 눈과 얼굴 이미지를 보완하기 위한 중요한 표현 수단임을 알 수 있었다. The purpose of this study is to look into the effect of wearing color lenses on ones image and was based on 221 college students in Gyeonggi-do and Gangwon-do. I examined how it appears as the evaluation factor visually. After by looking in the different image effect and relevance as to the classified evaluating factors, I tried to look into what effect the color lenses has on woman eye and image. The result is as follows. It appears that wearing color lenses makes one look fancier, more attractive, sophisticated, and favorable, whereas not wearing color lenses makes one look softer, weaker, more innocent, and comfortable. Analyzing these evaluations showed that wearing color lenses has most to do with attractiveness followed by pureness, familiarity, and decorativeness in order, whereas not wearing color lenses has most to do with familiarity followed by attractiveness, pureness, and decorativeness. It is considered that eyes with color lenses on them make the person seem decorative, attractive, and pure, which brings effect of improving ones eye and face image. Analyzing the correlation between each color lenses-wearing factor and ones image showed that when a person is wearing color lenses, the more the person is considered decorative, pure, and attractive, the more it has to do with improving the persons eye and face image. The result, therefore, shows that wearing color lenses makes ones eye and face image attractive, pure, and decorative, and wearing them is an important means to improve ones eye and face image.
