Where no records are available at a site, a preliminary estimate may be made from relations between floods and catchment characteristics. A number of these characteristics were chosen for testing and were measured for those catchments where mean annual flood estimates were available. Although the improvement using extended data in regression of flood estimates on catchment characteristics was small, this may be due to the limitations of the regression model. When an individual short term record is to be extended, more detailed attention can be given; an example is presented of the technique which should be adopted in practice, particularly when a short term record covers a period which is known to be biassed. A method of extending the peaks over a threshold series is presented with a numerical example. The extension of records directly from rainfall by means of a conceptual model is discussed, although the application of such methods is likely to be limited by lack of recording raingauge information. Methods of combining information from various sources are discussed in terms of information from catchment characteristics supplemented by records. but are generally applicable to different sources of information. The application of this technique to estimating the probable maximum flood requires more conservative assumptions about the antecedent condition, storm profile and unit hydrograph. It is suggested that the profile and catchment wetness index at the start of the design duration should be based on the assumption that the estimated maximum rainfall occurs in all durations centered on the storm peak.

김가현,권용선 한국응용과학기술학회 2018 한국응용과학기술학회지 Vol.35 No.2

This study is a descriptive study to analyze the hand washing practice of nurses working in clinic applying health belief model. This research involved 162 clinical nurse at G city . The data were collected from Sep 1, 2017 to Oct 31, 2017. The collected data were analyzed using an independent t-test, 1-way ANOVA, pearson's correlation coefficient and multiple regression analysis, where p-values of <0.05 were considered statistically significant by using SPSS 20.0. The overall practice of hand washing by general subjects were high 3.1 in all subjects, but there was no statistically significant difference. Health beliefs about hand washing practice according to general characteristics showed significant difference in perceived benefits (p<0.05), and there was a significant difference in perceived benefits and perceived barriers in age(p<0.05). In regard to the correlation among the subfactor of health beliefs, benefits had a statistically significant negative correlation to barriers and, positively correlated to cues to action. The results of this study suggest that continuing education of infection management in hospitals considering health beliefs about proper hand washing training will enhance hand washing practice. 본 연구는 건강신념모형을 적용하여 임상에서 근무하는 간호사의 손씻기 수행도를 분석하기 위한 서술적 조사연구이다. 본 연구의 대상은 G 광역시에 위치한 일개 병원에 근무하는 임상 간호사 162명 이다. 자료수집은 2017년 9월 1일부터 2017년 10월 31일까지였다. 수집된 자료는 SPSS (SPSS Version 20.0, IBM, US)를 이용하여 빈도분석, 백분율, 일원분산분석, t-검정, pearson 상관계수분석 및 다중회귀 분석으로 통계처리 하였다. 일반적 특성에 따른 손씻기에 대한 수행도는 모든 영역에서 평균은 3.1점으로 높았으나 통계적으로 유의한 차이는 보이지 않았다. 일반적 특성에 따른 손씻기에 대한 건강신념은 연령에 서는 지각된 유익성 영역에서 유의한 차이를 보였으며(p<0.05), 근무연수에서는 지각된 유익성, 지각된 장애성 영역에서 유의한 차이를 보였다(p<0.05). 다섯 개의 하위영역간의 상관관계를 분석한 결과는 지각된 유익성과 지각된 장애성은 부의 상관관계를 나타냈으며, 수행을 위한 동기는 정의 상관관계를 보였다. 본연구의 결과를 통해 손씻기에 대한 건강신념을 고려한 지속적인 병원에서의 감염관리교육과 올바른 손씻기 교육을 진행한다면 손씻기 수행도가 높아질 것으로 판단된다.

Purpose : Using a descriptive survey design, this study investigated the relationship between the types of violence experienced, self-esteem, and organizational commitment among emergency room (ER) nurses. Methods : A descriptive survey was conducted on 124 ER nurses working in two tertiary hospitals and three general hospitals in Busan Metropolitan City. Data were collected from October 15th to October 30th, 2019, and analyzed using independent t-tests, one-way ANOVA, and the Scheffé test. Results : In the relationship between the types of violence experienced, self-esteem, and organizational commitment, a weak negative correlation (r=-.27, p=.002) was found between the type of violence experienced and organizational commitment. Conclusion : The study findings showed that it is necessary to reduce violent experiences to increase the organizational commitment of ER nurses. To this end, it is vital to create a safe working environment in emergency rooms, which are often exposed to violence, and to establish policies that prevent and protect ER in advance from various factors that cause violence.

팝 아트 회화에서 분홍색의 의미와 상징성 연구

김가현,안진의 한국기초조형학회 2021 기초조형학연구 Vol.22 No.2

The purpose of this research is to draw the expression characteristics of the color pink and expand the symbolic meaning of Pop Art paintings that have given a strong visual effect to the public. For this, I.R.I Image Scale was used to analyze the color scheme imaging of works that were particularly prominent in the use of the color pink among paintings that appeared in the UK, which was the starting point of Pop Art, the US, which was the center of Pop Art, and Japan and China, which took various forms of spread. As a result of the research, leading with UK Pop Art which had political and social criticism or satirical character, US Pop Art expressed the reality of modern people becoming insensible in the repetitive mass media and overflowing products caused by industrialization through popular images. At this time, the color pink appeared as a feature that was fancy and attracting attention. Japanese Pop Art was reinterpreted as Neo-Pop Art, which was fused with “kawaii” animation to suit the national character, and has established a unique style of Japan, and the pink color showed fantastic images like animation. Chinese Pop Art was Political Pop Art as a Cynical Realist, in which Chinese artists satirized or accused the political situation of China in the 1970s, which experienced political state of confusion. The pink used in Chinese Pop Art was expressed as a cold pink with high attention to fit the content of cynical critique of reality. Pink is often used as a fragile and feminine color image. However, as a result of analyzing Pop Art paintings of each country in which pink was used, it was confirmed that pink caused a dynamic and fantastic color psychology to the public, and that it has a strong characteristic that is fancy or attracts attention. This overwhelming visual expression characteristic of pink has a very deep connection with Pop Art that expresses desire based on popularity, consumption, and fashionableness, and it is suitable for expressing Pop Art. It is expected that this research will contribute to the expansion of the meaning and symbolism of the color pink. 본 연구는 대중에게 강력한 시각적 효과를 주었던 팝 아트(Pop Art)회화를 대상으로 분홍색의 색채표현특징을 도출하고 상징적 의미를 확장하는 데 있다. 이를 위해 팝 아트의 출발점이었던 영국, 중심이되었던 미국, 다양한 확산의 모양을 띠었던 일본과 중국에 나타나는 회화 가운데 특히 분홍색의 활용이두드러진 작품의 배색 이미지를 I.R.I Image Scale로 분석하였다. 연구 결과 일상적이고 대중적인 이미지를 통해 정치적 사회 비판이나 풍자적인 성격을 가진 영국 팝 아트를 필두로, 미국 팝 아트는 산업화로 인해 넘쳐나는 상품과 반복되는 대중 매체 속에서 무감각해지는 현대인의 실상을 표출하였으며, 이때분홍색은 화려하고 주목성이 강한 특징으로 나타났다. 일본 팝 아트는 국가적 성격에 맞게 ‘가와이이(可愛い)’한 애니메이션과 융합된 네오팝 아트(Neo-Pop Art)로 재해석되며 일본만의 독자적인 양식을 구축하였으며, 분홍색은 애니메이션처럼 환상적인 이미지를 보여주었다. 중국 팝 아트는 문화대혁명과 천안문 사태 등의 정치적 혼돈을 겪은 1970년대 중국 작가들이 중국의 정치적 상황을 풍자하거나고발하는 냉소적 사실주의(Cynical Realist)로써 정치적 팝 아트(Political Pop Art)였다, 이때 사용된분홍색은 냉소적인 현실 비판이라는 내용에 걸맞게 주목성 높은 차가운 분홍으로 표현되었고기존의 사회주의적 사실주의와는 다른 개성적인 이미지로 작용했다. 분홍색은 종종 유약하고 여성적이라는색채 이미지로써 통용된다. 하지만 분홍색이 사용된 국가별 팝 아트 회화를 분석해본 결과, 분홍색은대중에게 다이나믹하며 환상적인 색채 심리를 유발하였고, 화려하거나 주목성이 강한 강렬한 특징이 있다는 점을 확인할 수 있었다. 이 점은 분홍색이 인간의 과시 욕망과 주목받고자 하는 욕망이 투영된색채임을 확인하는 근거가 되기도 하였다. 이러한 분홍색의 압도적인 시각적 표현특징은 대중성, 소비성, 유행성을 기반으로 욕망을 표출하는 팝 아트와 매우 깊은 연관을 갖고 있으며, 팝 아트를 표현하는데매우 적합한 것이었다. 본 연구가 분홍색의 색채상징 의미의 확장에 기여되길 기대한다.

박막 실리콘 태양전지의 광열화현상 연구: 비정질 실리콘 태양전지 및 나노양자점 실리콘 박막 태양전지

김가현 한국태양에너지학회 2019 한국태양에너지학회 논문집 Vol.39 No.1

Light induced degradation is one of the major research challenges of hydrogenated amorphous silicon related thin film silicon solar cells. Amorphous silicon shows creation of metastable defect states, originating from elevated concentration of dangling bonds during light exposure. The metastable defect states work as recombination centers, and mostly affects quality of intrinsic layer in solar cells. In this paper we present results of light induced degradation in thin film silicon solar cells and discussion on physical origin, mechanism and practical solutions of light induced degradation in thin film silicon solar cells. In-situ light-soaking IV measurement techniques are presented. We also present thin film silicon material with silicon nano-quantum dots embedded within amorphous matrix, which shows superior stability during light-soaking. Our results suggest that solar cell using silicon nano-quantum dots in abosrber layer shows superior stability under light soaking, compared to the conventional amorphous silicon solar cell.

김가현,오지은,조미숙 한국식생활문화학회 2022 韓國食生活文化學會誌 Vol.37 No.2

This study identifies the perceptions and choice attributes toward plant-based foods and identifies the differences betweenvegetarians and omnivores. We conducted an online survey of 245 vegetarians and 246 omnivores. The results reveal asignificant difference between vegetarians and omnivores. Compared to omnivores, vegetarians perceived that plant-basedfood products would be ‘good taste’, ‘animal-friendly’, and ‘consistent with their personal value’. Omnivore scores werehigher in the perception that it would be ‘good for health’ and ‘environment-friendly’. No statistically significant differencewas obtained between both diet groups when considering the factor of nutrition. When considering choice as an attributefor plant-based food products, vegetarians responded that ‘ingredients’ were the most important, while omnivoresresponded that ‘taste’ was the most important. These results can be used as basic data for developing and promoting plant based food products in South Korea.

탈기체분석 및 타원편광분광법을 통한 박막 실리콘의 물성분석법 연구

김가현 한국진공학회 2023 진공 이야기 Vol.10 No.1

This paper reviews analysis methods of hydrogenated amorphous silicon thin films by using thermal desorption spectroscopy and spectroscopic ellipsometry. Amorphous silicon has disordered atomic structure, and consists of dangling bonds, which work as electronically active defects. These defects can be passivated by hydrogen, and the material is called hydrogenated amorphous silicon. Hydrogen exodiffusion provides information on Si-H bonding and microstructure of the material. Therefore, Si-H bonding property and microstructure of the films can be analyzed in detail. Spectroscopic ellipsometry is a powerful tool for analyzing optical properties of material. Ellipsometry measurement results is usually given by change of polarization state of probe light, so the measured result should be properly treated and transformed to meaningful parameters by transformation and modeling of the measurement result. In case of hydrogenated amorphous silicon, Tauc-Lorentz dispersion is usually used to model the measured ellipsometry spectrum. Modeling of spectroscopic ellipsometry result of hydrogenated amorphous silicon using Tauc-Lorentz dispersion is discussed.

완벽주의와 사회불안의 관계에 대한 메타분석

김가현,김은하 한국상담학회 2020 상담학연구 Vol.21 No.5

This study conducted a meta-analysis to investigate relations between perfectionism and social anxiety. A total of 45 papers published from 2006 to 2019 were included in the analysis. The general characteristics of the paper analyzed were as follows: by study subjects, there were no paper for men only, 2.2% for papers for women only, and 97.8% for both men and women. By age group, research on college students was the most(51.1%). HMPS was most frequently used as 44.4% for the perfectionism scale. As for the social anxiety scale, 29% of the papers were measured as a single scale, and 71% of the papers were used by mixing two scales. The meta-analysis results led to the major following findings. First, perfectionism and social anxiety were correlated and had statistically significant medium effect size. Second, to verify the heterogeneity of the effect size meta ANOVA was conducted, the results showed statistically significant differences according to the sub-dimensions of perfectionism, adaptive/maladaptive perfectionism, perfectionism scale, social anxiety scale, and the group of age. Third, according to the sub-dimensions of perfectionism, ‘Inconsistency’ in APS-R showed the largest effect size, and ‘Doubts about action’ and ‘Concern over mistakes’ in FMPS, ‘Social-Prescribed Perfectionism’ in HMPS, followed by ‘Parental crticism’ in FMPS. But, ‘Inconsistency’ in APS-R was insufficient to be seen as a reliable result, as it had only 3 effect sizes. This study is meaningful that it comprehensively examined the precedent studies of the relationship between two variables according to mutidimensional characteristics of perfectionism. Based on these conclusions, the limitations of this study and suggestions for follow-up research were discussed. 본 연구는 완벽주의와 사회불안의 관계에 대한 국내 연구 결과를 통합적으로 분석하기 위해 2006년부터 2019년까지 출간된 45편의 논문을 선정하여 메타분석을 실시하였다. 분석대상 논문의 일반적 특성은 다음과 같다. 남성 대상 논문은 없었으며, 여성 대상 논문 1편, 혼성 대상 연구는 44편이었다. 연령별로 대학생 대상 논문이 가장 많았고(51.1%), 완벽주의 척도는 HMPS가 44.4%로 가장 많이 사용되었다. 사회불안 척도는 단일척도를 사용한 논문이 29%, 두 가지 척도를 혼합하여 사용한 논문이 71%였다. 메타분석을 통해 확인된 결과는 다음과 같다. 첫째, 완벽주의와 사회불안은 유의한 수준의 중간 효과크기로 상관이 있었다. 둘째, 효과크기의 이질성 확인을 위한 메타 ANOVA를 실시하였으며, 그 결과 완벽주의 하위차원, 적응적/부적응적 완벽주의, 완벽주의 척도, 사회불안 척도, 연구대상의 연령에 따라 통계적으로 유의한 차이가 나타났다. 셋째, 완벽주의의 하위차원은 APS-R의 ‘불일치’, FMPS의 ‘수행의심’, ‘실수염려’, HMPS의 ‘사회부과 완벽주의’, FMPS의 ‘부모비난’ 순으로 큰 효과크기를 나타내었으나, APS-R의 불일치는 효과크기 수 3개로 유의미한 결과로 보기 어려웠다. 본 연구는 국내의 완벽주의와 사회불안의 관계에 대한 선행연구를 종합적으로 살펴보고, 완벽주의의 다차원적 특성에 따른 두 변인의 관계를 비교 분석하였다는 점에서 의의가 있다. 이러한 결론을 바탕으로 본 연구의 제한점과 후속연구를 위한 제언을 논의하였다.
