조현경,김치선,홍창희 한국물리학회 2002 새물리 Vol.45 No.3

GaN p-i-n ultraviolet photodetectors grown by metalorganic chemical vapor deposition have been fabricated and their performances investigated. Under the optimized growth conditions of p-GaN, the detectors with a high visible blindness were successfully achieved and also the effect of p-layer thickness on their characteristics explored. For optimized p-i-n photodetector with 1000 Å thick p-layer, the visible-to-UV rejection ratio and the responsivity were over 106 and 0.19 A/W at 352 nm, respectively. 유기금속 화학 기상증착법으로 GaN p-i-n 구조를 성장하여 자외선 검출기를 제작하고 그 특성을 조사하였다. p-GaN의 성장조건의 최적화를 통하여 고효율의 가시빛 맹목(visible blindness)을 가진 p-i-n 검출기가 제작되었으며, 또한 p층의 두께에 따른 검출기의 특성을 분석하였다. 그 결과 두께가 1000 Å의 p층을 가진 p-i-n 구조에서 352 nm의 피크 파장에서 반응도(responsivity)가 0.19 A/W, 반응비(rejection-ratio)가 106이상인 고품위 자외선 검출기를 구현하였다.

하천형상에 따른 유출특성의 변화에 관한 수치적 연구

조현경 영남이공대학 1998 論文集 Vol.27 No.-

This study is two goals. One is the exploration of a variation of runoff characteristics for single and looped channel networks. The other is the exploration of a variation of runoff characteristics for the influence of some channel and tloodplain hydraulic and geometric properties on the frequency distribution of peak flood flow rates as flood waves propagate downstream. For this purpose, a one-dimensional flood routing model is used to a numerical simulation. In this paper the finite difference method is applied to the solution of the Saint-Venant equations. Results show that the peak discharge and peak time in the looped channel becomes less than single channel and it influences a variation of downstream runoff characterist-ics for some channel and floodplain hydraulic and geometric properties.

Objectives : This study was done to investigate clinical frequency and correlation among the indicators of dampness-phlegm pattern identification settled by tentative Korean Standard Differentiation of the Symptoms and Signs for Stroke. Methods : The subjects were 147 hospitalized patients with stroke, and a list of registry was made for each of them. Among the five types of pattern identification, fire-heat, dampness-phlegm, blood-stasis and deficiency of Qi and of Yin, those that have shown a high frequency in dampness-phlegm type were categorized as the dampness-phlegm pattern group. Frequency of dampness-phlegm indicators was compared with those from the non-dampness-phlegm pattern group. Correlations among dampness-phlegm indicators were also studied. Results : 1. Dampness-phlegm pattern group included 26 patients out of 147. 2. Among the indicators of dampness-phlegm pattern. those, in order of highest frequency, were 'tiredness or sluggishness', 'white Coated tongue' and 'sputum'. 3. In comparing dampness-phlegm pattern group with non-dampness-phlegml group, the indicators such as 'lightheadedness', 'nigrescence', 'sputum', 'dermatic dysaesthesia' showed significantly high frequency. 4. Among the indicators, 'sputum' and 'tiredness or sluggishness', 'sputum' and 'yellow coated tongue', and 'white coated tongue' and 'yellow coated tongue' showed significant correlation. 5. In investigation of the correlation of scale in symptoms, various results such as positive correlation and negative correlation were obtained. Conclusion : In this study, more sensitive indicators of dampness-phlegm pattern identification were found. Based on these results, it is suggested that a more practical Korean Standard Differentiation of the Symptoms and Signs of Stroke would be established through continuous clinical studies by giving weight on each specific type of pattern identification.

In the modern era, the necessity of color capability in the digital era is the demand of the era, and research on improving color practice on the subdivided digital four areas that are not in the existing practice is needed. For digital majors who are difficult to solve in existing paint color practice, classes in digital color practice in four more specialized areas are needed, and the use of efficient artificial intelligence was studied for classes in digitized color and color sense. In this paper, we tried to show the expansion of the color practice area by suggesting digital color practice and color matching method based on Photoshop artificial intelligence and big data technology that existing color and color matching were practice that only CMYK could do. In addition, based on the color quantification data of individual users provided by the latest Adobe Sceney program artificial intelligence, the purpose of the practice was to improve learners' predictions of actual color combinations and random colors using filter effects. In conclusion, it is a study on the use of programs that eliminate ambiguity in the mixing process of existing paint practice, secure digital color details, and propose a practical method that can provide effective learning methods for beginners and intermediates to develop their senses through artificial intelligence support. The Adobe program practice method necessary for coloration and main color through theoretical consideration and improvement of teaching skills that are better than existing paint practice were presented.

조현경 국제문화기술진흥원 2018 The Journal of the Convergence on Culture Technolo Vol.4 No.4

Recent Korean policies have been suggested as globalization, openness and expansion of the working world through k-move. In an era of communication, interest and expectations for overseas employment and advancement into the country are increasing as a way to solve the global trend of employment abroad. Until recently, overseas employment support systems and policies have been implemented in a variety of ways through collaboration with universities and government agencies, so this paper will study Australia's national support and vocational education systems, for example, and Australia's foreign employment conditions and the overall system. This will help overseas employers and policy makers understand the status quo and will be meaningful as additional data needed by Korean universities and policy agencies. On the basis of these data, it was proposed as a conclusion on how to supplement the policy. Through the text, we aim to help establish practical goals and solutions that will help job applicants from overseas Australia, government and university policy systems. Accordingly, the main body presented the policies and assessment methods of the Australian vocational system, the overseas job support system, the corresponding service support system, and the overseas conditions and information on the program, and, in conclusion, the implications of policy supplementation. 최근 한국의 정책에서는 k-move를 통한 노동세계의 국제화, 오픈형, 확대로 발전되고 있다. 소통의 시대에 세계적인 추세인 해외 취업 진출을 해결하기 위한 방법으로, 해외 고용과 주요 국가 진출에 대한 관심과 기대가 증가하고 있다. 최근까지 해외고용 지원 시스템과 정책들은 대학과 정부기관의 협력을 통해 다양한 방식으로 시행되고 있기에, 본 논문에서는 호주를 사례로 국가 지원 및 직업 교육 시스템에 대한 연구와 호주의 외국인 고용 조건과 전반적인 직업 교육의 시스템을 연구할 것이다. 이것은 해외 취업자와 정책 담당자들에게 현황에 대한 이해에 도움이 될 것이며, 한국 대학과 정책 기관에 필요한 부가 자료로서 의미를 가진다. 이러한 자료를 근거로 정책의 보안 방안을 결론으로 제안하였다. 본문을 통하여 해외 호주 취업 지원자들에게 도움이 될 실질적인 목표와 해결점, 정부와 대학 정책 시스템 구축에 도움이 되고자 한다. 이에 본론에서는 호주직업제도의 정책과 평가방식, 해외직업지원제도 및 해당업무지원제도, 프로그램에 대한 해외여건과 정보를 제시하고, 결론으로서 향후 활성화에 관한 정책적 보안 시사점을연구하였다.
