애니메이션 얼굴 이미지의 선호 피부색

한혜진(Hye Jin Han) 한국애니메이션학회 2015 애니메이션연구 Vol.11 No.1

선호 피부색은 색 재현 분야에서 중요한 주제로 긴 역사를 바탕으로 방대한 연구가 축적되어 있다. 그러나 애니메이션에서의 선호 피부색은 연구된 사례가 별로 없다. 최근 제안되었던 캐릭터의 피부색을 중심으로한 애니메이션 색채 설계(한혜진·이성은, 2014)를 발전시키기 위해, 실제 피부색과는 다른 경향을 가진 애니메이션에서 선호 피부색을 새로운 연구 대상으로 주목할 필요가 있다. 따라서 이 연구에서는 애니메이션 얼굴 이미지의 선호되는 피부색을 알아보고자 했다. 첫째, 실제 일본의 스튜디오 지브리에서 제작된 애니메이션에 쓰이고 있는 피부색의 범위를 조사했다. 조사방법으로 고정된 모니터에 애니메이션 화면을 띄우고 휘도계로 측색을 실시했다. 측색 결과, 실제 피부색의 측색치보다 범위가 넓어져 있어 피부색에 대한 강한 기억색의 영향을 확인했다. 둘째, 애니메이션 얼굴 이미지의 선호 피부색을 순위상관법을 이용하여 조사했다. 실험 방법으로 피험자에게 동일한 조건에서 애니메이션의 얼굴 이미지와 사각형의 색표를 이용하여 선호하는 피부색의 순위를 매기게 했다. 각각의 매겨진 순위를 이용하여 스페어만순위상관계수(Spearman’s Rank Correlation Coefficient)를 계산했다. 자극에 따른 순위상관계수를 비교한 결과, 애니메이션 얼굴 이미지와 사각형 색표에서 선호 피부색이 다른 경향을 띤다는 것이 나타났다. 애니메이션 얼굴 이미지에서도 선호 피부색이 존재한다는 것이 심리물리학적인 실험을 통하여 확인되었다. 더불어 애니메이션 제작을 위한 색 재현 데이터베이스화의 가능성을 확인했다. The study of preferred skin color has been accumulated based on long history, because of important theme in color reproduction. However, preferred skin color in animation has been hardly researched. For developing a proposal of color planning for film image based on character’s skin color(Han&Lee, 2014), the study of preferred skin color in animation, which has unique trends differed from real skin color’s one, is needed to pay attention as a new theme. In this study, preferred skin color in animation will be clarified. Firstly, skin colors in Japanese studio ghibli’s animation were investigated for making sure of the range of skin color in real animation fields. Showing still images of animations on a monitor, skin colors of the images were measured by a luminance meter. Because skin colors’ in the animations were wider than real skin colors’ one, strong effects of memory color could be considered. Secondly, preferred skin color of animation facial images was researched by rank order method. In the same experiment’s condition, subjects determined the raking of preferred skin color using facial images and rectangle color chips. The ranked orders of preferred skin color were calculated as Spearman"s rank correlation coefficient. The differences between facial images and rectangle color chips were identified, comparing the rank correlation coefficients. Through the psychological physical experiment, existences of preferred skin color in animation were ensured. Moreover, possibilities to database for color reproduction of animations were identified.

토양 미생물인 Streptomyces tubercidicus에서 분리한 GTPcyclohydrolase Ⅰ 저해제

한지만,김시욱,이인화,박열,정혜광,윤성명,유진철 조선대학교 약학연구소 1998 藥學硏究誌 Vol.19 No.1

GTP cyclohydrolase I (EC 3.5.4.16) catalyzes the conversion of GTP to D-erythro-7,8-dihydroneopterin triphosphates and formic acid. and thus performs the first committing step in the biosynthesis of the pteridine moiety of folk acid in microorganisms and of tetrahydrobiopterin in higher animals. GTP cyclohydrolase I isolated from Streptomyces tubercidicus was inhibited by DL-6-methyl-5,6,7,8-tetrahydropterin and xanthopterin, and was not inhibited by tetrahydrofolic acid, pterin, pterin-6-carboxylic acid, biopterin, neopterin, ribofravin. These results suggest that bacterial GTP cyclohydrolase I may be regulated by its metaboilic end product.

Lipopolysaccharide, Dexamethasone, 및 N-Nitro-L-Arginine Methyl Ester가 흰쥐 간 조직의 프리라디칼 발생과 제거에 미치는 영향

한기정,김석배,김양균,윤혜영,백광진,이희성,권년수 중앙대학교 의과대학 의과학연구소 2003 中央醫大誌 Vol.28 No.1

Lipopolysaccharide (LPS) stimulates various immune and inflammatory reactions to induces the generation of reactive oxygen intermediates (ROI) and reactive nitrogen intermediates (RNI). ROI and RNI are free radicals with very high reactivity, oxidize cellular constituents including proteins and lipid membranes, and thus play important roles in the pathogenesis of tissue damages in LPS-induced septic shock. The present study examined effects of dexamethasone (DexM), and N-nitro-L-arginine methyl ester (L-NAME) on the generation of ROI and RNI, and on the activities of enzymes removing ROI in the liver of rat model of septic shock. DexM has widely been used as an immunosuppressant. L-NAME has known to block synthesis of nitric oxide (NO), the main RNI, by inhibiting NO synthase (NOS). LPS (10 mg/kg body weight) markedly enhanced NO generation in serum and liver. The increased NO generation was completely blocked by pretreatment with DexM (10 mg/kg) and effectively inhibited by L-NAME (10 mg/kg). Induction of NOS protein expression by LPS was demonstrated by a Western analysis. The NOS expression was completely blocked by DexM pre-treatment, and markedly inhibited by L-NAME. However, the generation of superoxide radical, an important ROI, was not enhance in rat liver by LPS, rather it was decreased a little. Superoxide radical production was increased by L-NAME treatment or combined treatment of DexM and LPS. The level of lipid peroxidation, an index for free radical-induced cell damage, was increased by either LPS or DexM. The enhancement of lipid peroxidation by DexM was abolished by adding LPS. DexM markedly enhanced the activities of ROI removing enzymes, superoxide dismutase, glutathione peroxidase and catalase. However, rats were treated with LPS in addition to DexM, the elevated activities of superoxide dismutase, glutathione peroxidase and catalase were abolished. These results provide information on the generation and removal of ROI and RNI by LPS, DexM and L-NAME in rat liver, and on development of drugs to inhibit free radical-induced liver damage in sepsis.

연구목적 : 외환위기 이후에 급증한 노숙자 문제는 경제적인 상황의 호전에도 불구하고 만성화하는 경향을 보이고 있다. 쉼터의 노숙자를 대상으로 정신질환의 유병율과 삶의 질에 대한 조사를 시행하였다. 방 법 : 2000년 3월에 서울의 대표적인 쉼터에 거주하는 노숙자220명을 대상으로 인구학적 자료에 대한 설문조사를 한 뒤 Structured Clinical for DSM-Ⅳ(SCID-I)을 이용하여 AxisⅠ의 주요 정신질환을 진단하였다. 또 SmithKline Beecham Quality of Life Scale(SBQOL)를 사용하여 삶의 질정도를 평가하였다. 결 과 : DSM-Ⅳ AxisⅠ의 정신질환 중 기분장애, 정신병적 장애, 물질 사용 장애에 대한 진단 평가 결과 상기정신질환의 전체 평생 유병율은 73.6%, 현재 유병율은 59.1%이었다. 알코올 의존과 남용의 평생 유병율은 59.5%로 가장 높았고, 기분장애와 장애가 각각 39.5%, 3.6%이었다. 삶의 질은 노숙의 기간이나 실직 기간과 유의한 관계가 없었고, 자신이 지각한 건강상태, 자살과거력, 우울장애 유무와 통계적으로 유의하게 상관관계가 있었다(p<0.01). 결 론 : 노숙자에서 정신질환 중 알코올 장애의 유병율이 가장 높았으며, 우울장애가 있는 경우에 삶의 질이 저하되는 것으로 나타났다. Objectives : Homeless people surged after financial crisis tend to be chronic despite late economic recovery. So we tried to estimate prevalence of mental illness and quality of life of the homeless population living in shelter. Method : The study subjects were 220 homeless peoples who stayed at a shelter in Seoul around March 2000. Questionnaires on sociodemographic data were administered to the subjects, and then diagnoses of major DSM-Ⅳ Axis I mental disorders were made using Structured Clinical Interview for DSM-Ⅳ Axis I Disorders(SCID). And quality of life(QOL) was evaluated by SmithKline Beecham Quality of Life(SBQOL). Results : The lifetime prevalence of major DSM-Ⅳ mental disorders(mood disorders, psychotic disorder, and substance use disorder) of 220 homeless people was 73.6%, and current prevalence was 59.1%. The lifetime prevalence of alcohol dependence and abuse was highest, 59.5% and those of mood disorder and psychotic disorder were 39.5%, 3.6% respectively. Quality of life was not significantly correlated with duration of homelessness and unemploy-ment but marital status, self perceive health status, suicidal attempt history were significant factors. The quality of life in the people with mood disorders were estimated to be lower than those with any other diseases(p<0.01). Conclusion : Alcoholism was the most prevalent mental disorder in homeless people and mood disorder was negatively related to the quality of life scale.

부산시의 O_3 농도 변화 특성 및 시정에 관한 연구

한영옥,배혜진 부산교육대학교 교육대학원 2000 논문집 Vol.2 No.-

This study analysed O_3 concentration data and various data of meteorological factors to investigate the characteristics of O_3 concentration variation and determined how the high air pollutants concentration was generated under the meteorological condition. It also studied visibility variation and visibility impairment factors. The characteristics of O_3 concentration variation and the characteristics of O_3 episode day(≥60 ppb) were discussed on the base of the O_3 concentration data by air quality monitoring system in Pusan. Also the characteristics of visibility variation and visibility impairment factors were studied on the base of the visibility data and meteorological data of Pusan Meteorological Administration. According to the work, O_3 concentration was increased comparing to the previous year and coastal area was higher O_3 concentration than other area. O_3 episode day is annually increasing and the frequency of episode day is the most in summer. The high concentration of O_3 were occurred in narrow bounds and were not continued for long. Low mean wind speed were important meteorological parameter accompanying with the high episode days. Visibility was gradually decreased until 1990 and after then it was on the increase but poor visibility range became longer than good visibility range. So many people felt air pollution more seriously. Visibility impairment were influenced by TSP concentration, NO_2 concentration, temperature, wind speed and relative humidity. Especially increase of TSP concentration and relative humidity had high generation of low visibility.

The chemical components of radish buds were investigated during the growth stage. The vitamin C and total phenol contents were lowered after 4 days of early sprout growth, and were 22.19 and 4.99 mg%, respectively.These increased according to the growth time, showing the highest value on day 8, 25.85 and 17.87 mg%, respectively. However, these values decreased around day 12, which seemed to be the bud end point. The major free sugar component of the radish buds was glucose, showinged the highest content on day 8. The total organic acid content gradually increased as the growth proceeded. The detected oxalic acid content was only small on day 8. During the early growth stage, the total and essential amino acids contents were 3,020~3,575 and 1,206~1,499 mg, respectively. These contents tended to decrease with growth time. Glutamic acid, aspartic acid and alanine were the major amino acid components (39%).

As the semiconductor wafer is required to be thinner for better compactness and higher integrity of the electronic products, mechanical dicing saw technique using the diamond blade is facing serious problems such as low cutting speed, tool wear, side wall crack and back side chipping. Recently, UV laser dicing process has emerged as an alternative methods to the blade dicing especially for the very thin wafers below 100㎛. In this study 355 nm UV laser dicing system has been developed in order to improve the productivity and reliability of ultra thin wafer dicing process. For the quality improvement of the developed dicing system various laser parameters are investigated such as power, speed and frequency of the laser beam. Moreover various measurement techniques are employed to evaluate the dicing quality using optical microscope, SEM and focused ion beam.
