Objectives : This study is designed to clarify whitening, anti-inflammatory effect of fractions extracted from the mixture of Phaseolus radiatus L. and ethanol. Methods : In this experiment, we were intended to reveal whitening, anti-inflammatory effect of fractions extracted from the mixture of Phaseolus radiatus L. and ethanol. The whitening activity was confirmed by UV blocking activity, tyrosinase inhibiting activity, and melanin formation inhibiting activity. Anti-inflammatory activity is confirmed by measurement of cytotoxicity level by MTT assay and measurement of Cytokine expression, which is the main mediator of inflammation reaction. Results : As a results, overall activity was high in the ethyl acetate fraction. Tyrosinase inhibitory activity was less than 20% at all concentrations, but the activity to inhibit melanin self-production was higher than that of ethyl acetate fraction at $32.19{\pm}2.79%$ at $100{\mu}g/m{\ell}$. And ethyl acetate fraction had a relatively high UV blocking activity. In the anti-inflammatory test, the concentration-dependent activity was shown, and the chloroform and ethyl acetate fractions showed significant NO production inhibitory activity. Cytokine expression was superior to that of the final stage of B cell differentiation, and cell viability was over 80% except for the chloroform fraction at the concentration of $200{\mu}g/m{\ell}$. Conclusions : The results of this experiment confirmed the whitening effect and anti-inflammatory effect of Phaseolus radiatus L.'s extracts and fractions and report the possibility of application as external medicine.

In this study, we have investigated the effect of the ambient gases on the characteristics of IZO thin films for the OLED (organic light emitting diodes) devices. For this purpose, IZO thin films were deposited by RF magnetron sputtering under various ambient gases (Ar, $Ar+O_2$ and $Ar+H_2$) at $150^{\circ}C$. In order to investigate the influences of the oxygen and hydrogen, the flow rate of oxygen and hydrogen in argon mixing gas has been changed from 0.1sccm to 0.5sccm, respectively. All the samples show amorphous structure regardless of ambient gases. The electrical resistivity of IZO film increased with increasing flow rate of $O_2$ under $Ar+O_2$ while under $Ar+H_2$ atmosphere the electrical resistivity showed minimum value near 0.5sccm of $H_2$. All the films showed the average transmittance over 85% in the visible range. The OLED device was fabricated with different IZO substrates made by configuration of IZO/${\alpha}$-NPD/DPVB/$Alq_3$/LiF/Al to elucidate the performance of IZO substrate. OLED devices with the amorphous-IZO (a-IZO) anode film show better current densityvoltage-luminance characteristics than that of OLED devices with the commercial crystalline-ITO (c-ITO) anode film. It can be explained that very flat surface roughness and high work function of a-IZO anode film lead to more efficient hole injection by reduction of interface barrier height between anode and organic layers. This suggests that a-IZO film is a promising anode materials substituting conventional c-ITO anode in OLED devices.

이유림 ( Yu Lim Lee ),문철 ( Moon Chul ) 한국기초조형학회 2012 기초조형학연구 Vol.13 No.5

영상 미디어 시대에 전통적인 시각표현기법만으로 독자들의 관심을 갖게 하기는 어려워졌다. 이미 다양한 복합미디어의 발달로 인해 우리들의 지각은 영상매체에 맞추어져 있으며, 이러한 발달로 다른 장르에서도 형식과 양식들의 변화가 일어나고 있고, 그림책에서도 변화가 자연스럽게 요구되고 있다. 본 연구는 영상으로 사고하는 영상 미디어 시대에 살고 있는 독자들에게 적합한 평면 그림책 표현기법을 모색하고, 화면의 다양한 시각 표현이 이루어질 수 있도록 하기 위함이다. 기본적으로 텍스트가 많지 않고 일러스트레이션, 기호, 부호 등의 시각이미지들을 활용해야하는 그림책은 시대의 흐름에 따라 여러 형태로 변화되고 있지만, 시대가 변하여도 그림으로 묶어있는 책 형식의 그림책의 본질은 변하지 않는다. 이것은 그림책에서는 시각 표현에 대한 관심이 지속되기 마련이고 꾸준히 연구해야 할 이유이다. 또한 그림책은 한정된 범위에서 이야기를 표현해야 하기 때문에 제한되어 있는 화면을 어느 장르보다 효율적으로 사용해야 한다. 따라서 연구자는 평면 그림책에서 텍스트의 의미를 효율적으로 나타내기 위하여 화면의 다양한 시각 표현이 이루어 질 수 있도록 영상을 분석하는 기법을 제시하는 허버트 제틀(Herbert Zettle)의 영상 미학 이론 중 영상의 시각화에 근거하여 평면 그림책에 활용할 수 있는 영상표현기법의 특징적인 요소들을 확인하였다. 평면 그림책에서 샷(shot)의 표현요소를 통한 화면구성을 살펴 본 결과, 샷의 크기, 샷의 각도, 샷의 시점의 사용과 그 효과는 각기 달랐고, 샷 사용의 변화만으로 작가가 원하는 그림책 분위기를 연출할 수 있음을 확인하였고, 샷의 더욱 다양한 기법의 활용 가능성도 알 수 있었다. In image media era, it is difficult for attract readers to the visual expressive technique of the traditional. According to the development of complex media, People are focused on image media. Therefore, Changing of the type and form is required not only other genre, but also picture book. We study to provide appropriate expressive technique of plain picture book for the readers who live in the image media era. We also study to find various visual expression of image in picture book. In modern society, the technology is developed, and picture book that uses visual grammar that can be expressed by many other formats. However, we think that the fundamental of picture book is not changed. That`s why we are interested about visual expression of picture book, and we have to study to picture book. As the page is limited, the picture book is required to express image effectively. According to the Herbert Zettle`s Visualization of Applied Media Aesthetics, we find that the important point of visual expressive technique that can be applied to flat picture book. It is for represent the meaning of text effectively, and for various visual expression in flat picture book. As we study the image of picture book through the expressive elements of shot, it shows that the effect of the size of shot, the angle of shot and the point of view of shot is different. Furthermore, author can make any kind of the mood of picture book by only using of shot.

이유림 ( Lee Yu Lim ),정재은 ( Chuang Jae Eun ) 한국소비자학회 2018 소비자학연구 Vol.29 No.2

본 연구는 복잡한 정보환경에 처한 소비자가 정보채널 이용에 따라 구매를 위해 정보를 탐색하거나 제품을 선택하는 과정에서 경험하는 소비자혼란(정보혼란, 선택혼란)의 양상이 어떠한지 살펴보고자 하였다. 이를 위해 최근 1년 이내 노트북을 구매한 경험이 있는 20, 30대 소비자를 대상으로 설문조사를 실시하였으며 총 320부가 실증분석에 사용되었다. 수집된 자료는 AMOS 22.0을 이용한 확인적 요인분석과 SPSS 20.0을 이용한 탐색적 요인분석, 군집분석, 그리고 ANOVA를 통해 분석되었다. 두 소비자혼란(정보혼란, 선택혼란)의 하위차원을 알아보고자 탐색적 요인분석과 확인적 요인분석을 실시한 결과 정보혼란은 과부화혼란과 불신혼란이 도출되었으며 선택혼란은 기능혼란과 브랜드혼란이 도출되었다. 정보채널 이용에 따라 소비자를 분류하기 위해 군집분석을 실시한 결과 ‘정보비교사이트 선호형(기본형)’, ‘정보확인 선호형’, ‘소비자정보채널 선호형’, 그리고 ‘적극적 정보탐색형’의 네 유형이 도출되었다. 네 유형별로 경험하는 소비자혼란을 살펴본 결과 정보채널을 다양하고 많이 이용하는 ‘적극적 정보탐색형’의 전반적인 소비자혼란 수준이 가장 높았으며, 직접 점포를 방문하거나 제품에 대한 지식을 타인에게 확인하는 과정을 거치는 소비자유형이 제품의 기능에 대해 낮은 수준의 혼란을 느끼고 있었다. 또한 다른 소비자로부터 발생된 정보를 많이 이용하는 소비자유형이 정보에 대해 높은 불신을 경험하는 것으로 나타났다. 본 연구는 정보제공자의 특성과 정보가 유통되는 경로의 특성을 반영하여 20, 30대 소비자를 유형화하고 각 유형에 따라 정보탐색과 제품선택 과정에서 경험하는 소비자혼란 양상을 고찰했다는데 의의가 있다 This study aims to segment 20s and 30s consumers by usage of information channel and understand differences in consumer confusion. Based on literature, consumer confusion includes information confusion, which is experienced in process of information searching for products, and choice confusion, which is experienced in process of deciding products to buy. A survey was conducted across 320 consumers who had bought laptop computer within a year between the age of 20 and 39. SPSS Win 20.0 was used for reliability, exploratory factor analysis and statistical analyses. AMOS 22.0 was used for confirmatory factor analysis. Results of exploratory factor analysis and confirmatory factor analysis indicated two subdimensions of information confusion, overload confusion and distrust confusion, and two subdimensions of choice confusion, function confusion and brand confusion. Cluster analysis result based on use of 18 information channels revealed that 20s and 30s consumers were grouped into four clusters. “Preferring Information Comparing Website Consumer Group” who uses the least overall information channels experienced the least overall consumer confusion. “Preferring to Confirming Information Consumer Group” who had have processes of visiting stores or confirming information to other consumers had the least confusion from product functions. “Preferring Consumer Information Channel Consumer Group” who tended to use much information from other consumers had the most distrust confusion. “Active Information Searching Consumer Group” experienced the most overall consumer confusion. This study has theoretical implications in that it grouped 20s and 30s consumers based on use of information channels and explored two type of consumer confusion (information confusion and choice confusion) across the groups.

이유림 ( Lee Yu Lim ),정민지 ( Jung Minji ),김아영 ( Kim Ahyoung ),박인형 ( Park In-hyoung ),정재은 ( Chung Jae-eun ) 한국소비자학회 2019 소비자학연구 Vol.30 No.6

본 연구는 소비자가 스마트워치를 사용하며 경험하는 혜택과 비용의 내용과 구조를 파악하고 기존연구에서 제시한 제품수용 이전의 지각된 혜택과 비용과 어떠한 차이점이 있는지를 알아보고자 하였다. 소비자가 경험하는 혜택과 비용의 대상을 스마트워치 기기와 어플리케이션으로 분류하였으며, 혜택은 효용적 혜택과 쾌락적 혜택을 포함하고 비용은 인지적 비용과 감정적 비용으로 구분될 것을 제안하였다. 이를 살펴보기 위해 국내에 출시된 스마트워치제품 가운데 애플워치를 사용한 경험이 있는 소비자가 작성한 텍스트 데이터를 소셜미디어에서 수집하고 R을 이용하여 텍스트 빈도분석, 군집분석 그리고 의미연결망분석을 실시하였다. 본 연구의 주요 결과는 다음과 같다. 소비자가 애플워치에 대해 느끼는 혜택과 비용의 대상은 ‘디자인 및 엑세서리’와 ‘부품 및 사후서비스’를 포함하는 기기 측면과 ‘생산성 및 음악 어플리케이션’과 ‘신체활동 관련 어플리케이션’을 포함하는 어플리케이션 측면으로 분류되었다. 의미연결망분석 결과 소비자는 착용감, 배터리 용량, 심미성 등에서 혜택과 비용을 동시에 경험하고 있었으며, 스마트워치의 주요 기능으로 제시되었던 신체활동 추적 어플리케이션으로 인해 신체상태 정보를 제공받거나 활동량을 증가하도록 동기를 부여받고 있었다. 반면 어플리케이션이 제대로 작동하지 않아 불편함을 경험하는 비용이 드러났으며 이러한 불편성과 편리성은 애플워치 사용경험으로 인한 혜택 및 비용의 내용을 구성하는 대표적인 메시지인 것으로 나타났다. 또한 기존연구에서는 제시되지 않았던 감정적 비용이 나타났으며, 스마트워치 수용 이전의 주요위험으로 간주되었던 프라이버시 및 개인정보 침해에 관련된 비용은 드러나지 않았다. 본 연구를 통해 스마트워치수용 이후 실제로 이를 사용하는 과정에서 경험하는 소비자의 혜택과 비용이 무엇인지 파악함으로써 어떠한 부분을 강화 및 보완해야 할지 실마리를 얻어 소비자의 일상과 가치에 부합하는 스마트워치를 개발하는데 도움이 될 것으로 기대된다. The purpose of this study is to examine smart watch consumers’ benefits and costs derived from the actual product experiences and how these benefits and costs are different from perceived benefits and costs before the product adoption. Objects of benefits and costs were classified into smart watch device and its application. The study suggests that the benefits include utilitarian and hedonic benefits, and the costs include cognitive and affective costs. In order to examine consumers’ opinion about smart watch experience, data written by Applewatch consumers were crawled from social media including Twitter, Facebook, and online community. Term frequency analysis, clustering analysis and semantic network analysis were conducted to understand contents and structure of the benefits and costs. The major findings are as follows. We found that objects of benefits and costs were divided into device, including ‘design and accessory’ and ‘component and after-sales service,’ and application, including ‘productivity and music application’ and ‘physical activity application.’The results of semantic network analysis showed that consumers gained both benefits and costs from wearability, battery durability and appearance. As suggested by extant literature, consumers were provided physical information and were motivated to exercise. On the other hand, they actually inconvenienced by systematic errors of various applications. In addition, the results found that affective costs which were overlooked in previous research. However, privacy risks which was proved as a major factor of decreasing intention to adopt smart watch was not revealed. The current study provides in-depth understanding of smart watch consumers’ benefits and costs from real-life product experience. It also suggests managerial implications to smart watch manufacturers regarding what they should strengthen and improve to enhance consumers’ satisfaction.

In the modern times, people’s desire for a good life has become more diverse due to rapid environmental changes. As they have extra time and energy in their lives, and women’s participation in the workplace increases, people’s desire to look young and beautiful has become stronger. Under these circumstances, cosmetologists who could satisfy such desire have become more important, playing a key role in providing beauty-related information and meeting aesthetic needs. Since beauty industry is highly dependent upon human resources, it is essential to develop and manage professional manpower. There have been some studies which concentrated on the positive aspects of employees such as the development and management of their strength, instead of focusing on the improvement of their negative behavior or problems. This kind of study emphasizing and developing employees’ positive aspects is a part of positive psychology. This study attempted to investigate the influence of positive psychological capital on job stress and analyze how they are correlated to each other against cosmetologists. For this, a survey was conducted against a total of 397 beauty industry workers, and the results found the followings: A significant influence was found in ‘self-efficacy-respecting other people’s opinions stress’, ‘optimism-self-development stress’ and other service-related stress. The above results confirmed that the necessity and perception of cosmetologists’ positive psychological capital would be a great help for both personal and organizational development in terms of the improvement of the efficiency of human resources. Furthermore, it’s anticipated that thanks to the utilization of positive psychological experiences, professionalism and pride would have an effect on correct job fulfillment.
