        III-V족 화합물 반도체 InSb 나노와이어의 전기화학적 합성 및 특성 평가

        이관희,이종욱,박호동,정원용,이종엽,Lee, Kwan-Hyi,Lee, Jong-Wook,Park, Ho-Dong,Jeung, Won-Young,Lee, Jong-Yup 한국전기화학회 2005 한국전기화학회지 Vol.8 No.3

        본 연구에서는 그동안 전기화학적으로 합성되지 못했던 III-V족 화합물 반도체 InSb를 구연산 용액으로부터 합성하였으며 자체 제조한 AAO를 나노템플릿으로 이용하여 정전압 도금을 실시하여 InSb 나노와이어를 제조하였다 제조된 InSb나노와이어는 X선 회절분석 결과 단결정의 나노와이어는 아니었으나 정확하게 화학양론을 만족시키는 화합물임을 확인하였고, 평판 박막 상태의 InSb와는 달리 나노와이어의 길이방향으로 (220) 방향의 결정이 주로 성장하는 우선결정방위를 가지고 있음을 알 수 있었다. 또한 집합적으로 배열된 상태에서 측정된 I-V특성 곡선에서는 n형 반도체의 특성을 보이되 밴드갭이 좁고, 전자이동도가 큰 InSb고유의 특성상 반금속과 유사한 전기적 특성을 보유하고 있음을 확인하였다. To the best knowledge, the formation and characterization of InSb nanowires have not been reported yet in spite of its good characteristics as a III-V compound semiconductor. The nanowire arrays were potentiostatically electrodeposited in a mixing solution of indium chloride, antimony chloride, citric acid, and potassium citrate according to our previous work on the electrodeposition of the stoichiometric InSb films. The electrical properties of nanowire arrays were measured by semiconductor parameter analyzer, and the microstructural analysis of the nanowires was conducted by employing XRD. Our experimental results indicate that the InSb nanowires have a highly preferred orientation of (220) direction and also exhibit electrical characteristics of n-type semiconductors which we, however, similar to semi-metals mainly due to their narrow band-gap and high electron mobility.

        地域住民의 健康行態와 國民健康增進法에 대한 認識 및 態度

        박재용,한창현,윤석옥,이관희 韓國保健敎育 ·健康增進學會 1999 보건교육건강증진학회지 Vol.16 No.2

        In order to ascertain the attitudes of residents to their health and the National Health Promotion Law, surveyors interviewed 1,220 subjects, 1% of men and women in Kyungsan city, who were twenty-year-old or more. The major findings are as follows : Men and women were 48.2% and 51.8%, respectively. The recognition rate of enacting and enforcing this law is 59.2% of men and 51.3% of women. With regard to the behavioral attitude to the health in the distinction of sex and age, current smokers are 31.2% of the interviewees, 61.6% of the men and 3.3% of the women. Current drinkers are 35.1%, 59.5% of the men and 12.3% of the women, but on the other hand there is little significance in the distinction of age. The acknowledgement proportion of enacting and enforcing this law is 59.2% of male and 51.3% of female. In terms of the recognition rate of the contents according to the general characteristics of interviewees, it appears that the indication of a warning expression on a packing paper of cigarette case and a liquor bottle is 92.4% and also the designation of a smoking free area in public facilities is 94.8%. Prohibition of cigarette-sale to the teenagers who are under 19, is 96.0%. Considering these facts, the recognition rate is high. On the contrary, 48.8% is accounted for encouraging a medical check-up before marriage which is in a low position. As a result of multiple logistic regression analysis, putting general characteristics and health behavior as a independent variable, the National Health Promotion Law as a dependent variable educational level, marital status, exercise and periodic medical examination are selected as significant variables. In case of having undergone a periodic medical examination the recognition rate was high whereas frequent exercise led to the low recognition rate. Concerning the details of the undertaking in accordance with each factor of general characteristics, the greater part of them have been appraised successfully whether it is recognized or not. On the other side, no effect got answered about the result of the undertaking subjects to general and peculiar behavior attitude towards health was in effect or not. A great majority approved of more reinforcement of legal regulation about smoking and drinking regardless of whether they perceived the details of the law of promotion of National Health Promotion Law or not. Additionally there was significant difference in reinforcing legal regulation of smoking and drinking in compliance with the attitude of the substance of this law. With regard to education, public relations and evaluation about national health through public health centers by our government, the younger and the higher in education they are, the more deficient they feel. First of all, those who were aware of the enforcement of this law as well as plenty of scarcity answered that better service of disease prevention had to be expanded than ever. In consideration of the above-stated results, the education to public health and the business of public relations should be reinforced and a practical campaign for health life should also spread out for the purpose of encouraging to practise healthy life-style.

        웃음치료 프로그램이 한센인의 자아존중감과 신체 이미지에 미치는 효과

        이관희 한국장애인복지학회 2014 한국장애인복지학 Vol.- No.25

        본 연구는 한센인을 대상으로 웃음치료 프로그램이 한센인의 자아존중감과 신체 이미지에 미치는 효과를 알아보고, 향후 한센인의 자아존중감과 신체 이미지를 증진시키기 위한 기초자료를 제공하는데 연구의 목적이 있다. 실험연구를 위하여 한센인 60명을 선발, 실험집단과 통제집단에 각각 30명씩 무작위로 배정한 후 실험집단 30명을 대상으로 2주 동안 60분씩 총 8회기 웃음치료 프로그램을 실시하였다. 웃음치료 프로그램 평가를 위한 자료는 프로그램 시작 전과 후에 설문지를 통하여 수집하였다. 수집한 자료는 IBM/SPSS 20.0 프로그램을 활용하여 분석하였으며, 적용된 통계기법은 빈도분석과 대응표본 t-test이다. 웃음치료가 자아존중감과 신체 이미지에 미치는 효과를 검증한 결과 자아존중감과 신체 이미지에 효과가 있는 것으로 나타났다. 한센인의 자아존중감과 신체 이미지 증진을 위한 제언을 하였다. The Purpose of this study was to verify the effects of laughter therapy program on the self-esteem and body image of Hansen patients in Korea in order to increase the quality of nursing for Hansen patients.

        어은리 주민들의 출입구에 대한 인식 -경북 영천시 금호읍 어은리의 사례-

        이관희 한국조경학회 2001 韓國造景學會誌 Vol.29 No.5

        This research is related to house entrance recognition of residents, who have long kept the entrance without a closing door in Eoeun village, Geumho, Keongbook. The purpose of the research was to interpret the recognition of a house entrance in Eoeun village with the theories of cultural ecology. Final results suggest the belief for all the inhabitant\`s welfare through anthropological adaptation to habitat. The fish in the Geumho River had sought the shelter from the heavy rain in summer. The Eoeun forest at the entrance of the village provided good shelter for the fish. The Eoeun residents thought that the safe shelter fur the river fish is also semantic for the people. They believed that if the fish could not find shelter, i.e., the Eoeun forest and left, the village could be not safe for their life. Therefore, even the entrance of house should be structurely opened for the fish shelter in a symbolic sense. The entrance without a closing door has implied that their life should depend upon their natural environments because they have believed that till now there have been no considerable accidents in the village.

        유전체 역학 연구를 위한 시료의 보관과 분석

        이관희,홍윤철,Lee, Kwan-Hee,Hong, Yun-Chul 대한예방의학회 2003 예방의학회지 Vol.36 No.3

        Because of advances of technologies in the field of genmic epidemiology in the recent years, specimen collection, storage and analysis became an essential part of research methodologies. DNA is now being used in epidemiologic studies to evaluate genetic risk factors and specimens other than the fresh whole blood can De used for PCR. Therefore, All nucleated cells, such as buccal swabs and urine specimens, are suitable for DNA analysis. For an unlimited source of genomic DNA, EBV transformation of lymphocytes can be used for immortalization. However, the type of specimen collected in genomic epidemiologic studies will depend on the study where the epidemiologist play a leading role for the design. We also briefly described various finds of analysis for SNP that is an essential part of the genomic epidemiology.
