안정선,C. H. Shin,H. J. Im,H. M. Kim,J. Sakai,J.O. Cha,K. B. Lee,여승준,T.H. Nam 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.50 No.6

Thin films of a TiNi shape memory alloy (SMA) were fabricated by using pulsed laser deposition (PLD). In order to investigate the effect of an ambient gas on the composition and the growth rate of the TiNi thin films, we performed PLD in vacuum ($5 \times 10^{-6}$ Torr) and in an ambient Ar gas of 200 mTorr. The fabricated films were characterized by using energy-dispersive X-ray spectrometry (EDXS), a surface profiler, and X-ray diffraction (XRD) at room temperature. The ambient Ar gas introduced during PLD was found to play an important role in enhancing the growth rate of the film. The enhanced deposition rates were of the order of $10^{-2}$ nm per pulse. The investigation into the composition of the films as a function of the target-substrate distance indicated that PLD in an Ar gas atmosphere made it possible to fabricate TiNi thin films with a stoichiometry close to that of the target; however, under vacuum, optimizing the deposition parameters controlling the composition was very difficult. The in-situ crystallization temperature (ca. 400 ${}^\circ\text{C}$) of the TiNi film prepared in an ambient Ar gas was found to be lower by ca. 200 ${}^\circ\text{C}$ in comparison with that of the TiNi film prepared under vacuum. The composition of the films prepared at various substrate temperatures from room temperature to 600 ${}^\circ\text{C}$ was found to be close to the target is composition, regardless of the substrate temperature.

집단미술치료 프로그램이 장애아동 부모의 양육스트레스감소와 자아존중감 향상에 미치는 연구

안정선,오승진 한국예술심리치료학회 2012 예술심리치료연구 Vol.8 No.1

본 연구는 사회적 안정망이 필요함에도 불구하고 관심의 영역에서 벗어나 있는 장애아동 부모의 양육스트레스 감소와 자존감 향상에 집단미술치료 프로그램이 효과가 있는지에 대해 알아보고자 하였다. 연구의 대상은 K시 소재한 K구 00보건소에서 장애아동을 둔 부모들 중 프로그램 모집공고를 보고, 이에 관심을 가지고 희망하는 부모들로서 미술치료에 대한 자발적인 참여 의지를 고려하여 프로그램에 참여하기로 동의한 부모들을 선정하여 연구 집단 8명을 대상으로 주1회 90분씩 모두 13회기에 걸쳐 집단미술치료 프로그램을 진행하였다. 집단미술치료에 따른 효과를 평가하기 위하여 ‘양육스트레스척도’와 ‘자아존중감척도’를 사용하여 사전검사와 사후검사간의 점수 차이를 분석하였다. 연구결과는 다음과 같다. 첫째, 집단미술치료가 장애아동부모의 양육스트레스 감소에 효과가 있는 것으로 나타났다. 둘째, 집단미술치료가 장애아동부모의 자아존중감 향상에 효과가 있는 것으로 나타났다. 향후 형제간의 관계 등을 포함한 복합적이며, 음악, 놀이 등 치료의 다양한 영역의 확장한 예술치료프로그램을 통해 후속연구가 이루어지기를 제언한다. The aim of this research is to observe if a collective art therapy was effective in reducing stress and improving self-esteem for the parents of disabled children whose social attention is rarely paid. K public health center in Kgu of K Metropolitan City selected the subjects, parents with challenged children who saw the application notice and voluntarily agreed to participate in the program. The group art therapy has been performed on 8 subjects of the research group once a week, 90 minutes each, a total of 13 times. ‘Scale of parenting stress’ and ‘Scale of self-esteem’ have been used to evaluate the effect of group art therapy. The score difference between pretest and posttest has been analyzed. The research results are as follows. First, group art therapy has an effect on decreasing parenting stress of parents with challenged children. Second, group art therapy has an influence on improving self-esteem of parents with disabled children. Further research should be done to explore complex relationships such as sibling relationships and on the expansion of Arts therapy area such as music and play.

Resonance Fluorescence Spectra of Zn-Substituted Myoglobin

안정선,C.H. Shin,H.M. Kim,J.O. Cha,여승준,Y. Kanematsu,Y. Nishikawa 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.50 No.6

Laser-induced fluorescence spectra, including narrow resonance lines, were measured for Zn-substituted myoglobin (ZnMb) in the lowest optical absorption band at 4 K by using a combination of short light pulses from a CW mode-locked laser for the excitation and a time-correlated single-photon counting method for the detection. The site-energy distribution function, {\it i.e.}, the distribution of the number of chromophore at various sites as a function of the zero-phonon transition energy, was determined from the excitation profile of the narrow resonance fluorescence line. The single-site fluorescence spectrum was determined by use of the saturation effect of laser-induced fluorescence. By comparing the laser-induced fluorescence spectra and the absorption spectrum with the spectra calculated by using the experimentally determined site-energy distribution and single-site fluorescence spectra, we found that the coupling between the electrons of the chromophore and the vibrations of the polypeptide was quite weak. Furthermore, the density of states of vibrational modes of myoglobin weighted by the coupling strength between the chromophore and the polypeptide chain was determined from the single-site fluorescence spectrum by solving an integral equation numerically

High-performance Semitransparent a-InGaZnO4 Thin-film Transistors Using Thin Al Electrodes

안정선,이광배 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.57 No.5

We investigate the feasibility of a 10-nm-thick semitransparent layer of Al as gate electrodes, instead of a conducting oxide, for bottom-gate-type amorphous indium gallium zinc oxide thin-film transistors (a-IGZO TFTs). Good adhesion with glass and plastic substrates is reported for 10-nm-thick Al-gate electrodes, with a sheet resistance of 32 Ω /ㅁ. The described semitransparent a-IGZO TFT also shows about a 70%-transmittance. A device operating at low voltage, a saturation mobility of 4.45 cm2/V s, a subthreshold swing of 1.06 V/decade, an off-current of about 10−11 A, and an on-off ratio of 107 at an operating gate voltage of 5 V are reported.

안정선,이진성,정병운,이병제,Ahn Jung-Sun,Lee Jin-Sung,Jung Byung-Woon,Lee Byungje 한국전자파학회 2005 한국전자파학회논문지 Vol.16 No.1

본 논문은 격리도가 향상된 US-PCS 대역 댁내용 중계기 안테나를 제안하였다. 일반적으로 중계기는 송신신호와 수신 신호 사이의 간섭을 줄이기 위해 격리도 확보가 필요하다. 그러므로 선형 편파 특성이 우수한 IBD(Integrated Balun Dipole) 안테나에 편파 다이버시티 기법과 캐버티, 멀티 캐버티, 개구정합 방법을 사용하여 안테나의 전후방비 개선을 위한 연구를 하였다. 시뮬레이션과 측정을 통해 개구 정합 방법과 편파 다이버시티 기법을 동시에 사용한 안테나는 US-PCS 대역에서 VSWR < 1.5의 대역폭, 8 dBi 이상의 이득, 그리고 약 15$\~$24dB의 격리도 개선효과가 있음을 확인하였다. This paper presents an antenna for US-PCS band indoor repeaters with enhancement of isolation. In common repeaters require an enough isolation to reduce the interferences between transmitted and received signals. Thus, it is investigated to improve front-to-back ratio of IBD(Integrated Balun Dipole) antenna which has a good linear polarization with a cavity or multi-cavity by using polarization diversity and aperture matching method. From the simulated and measured results, the antenna realized by using polarization diversity and aperture matching method has a VSWR below 1.5, gain over 8 dBi and enhanced isolation of 15$\~$24 dB in US-PCS band.

한국인의 기후변화 신념, 위험인식, 대응행동: 커뮤 니케이션 채널 유형의 영향을 중심으로

안정선,김여정 경희대학교 사회과학연구원 2022 社會科學硏究 Vol.48 No.2

한국인의 기후변화 신념, 위험인식, 대응행동(개인행동, 정책지지) 간의 관계와 커뮤니케이션 채널(전통미디어 vs. 소셜미디어 vs. 대인 커뮤니케이션)의 역할을 탐구하였다. 기후변화 신념은 위험인식을 매개하여 개인행동과 정책지지에 정적인 영향을 주었다. 이러한 영향은 커뮤니케이션 채널별로 다르게 나타났다. 전통미디어는 기후변화 신념에 정적인 영향을 미침으로써 간접적으로 개인행동과 정책지지에 영향을 미쳤고, 직접적으로 대응행동에 정적인 영향을 주었다. 소셜미디어는 위험인식에 유의한 영향을 주어 간접적으로 개인행동과 정책지지에 정적인 영향을 주었다. 대인 커뮤니케이션은 위험인식, 개인행동, 정책지지에 정적인 영향을 주어 대응행동에 직간접적으로 영향을 주었다.

안정선,김희경,최은숙 지역사회간호학회 2003 지역사회간호학회지 Vol.14 No.1

Purpose: The purpose was to investigate the factors influencing the alcohol consumption behavior of adolescents to provide basic data for a nursing intervention program to improve health management and prohibit alcohol consumption. Method: The subjects were 306 university students, living in K city in Chungnam province from April 1 to 20th, 2002. The instruments used were the alcohol consumption behavior scale, that is the drinking intensity score, and developed by Shin's scale of drinking problem, refusal self-efficacy scale by Aas et. al.(1995), alcohol expectancy by Goldman et. al.(1989), TPQ scale by Cloninger(1991), depression scale by Zung, family cohesion scale by Olson et. al.(1983). The data were analyzed using descriptive statistics, Pearson correlation coefficient, t-test, ANOVA, and stepwise multiple regression by using SPSS &SAS program. Results: The multiple regression analysis revealed that the most powerful predictor of alcohol consumption behavior was the influence of friends(drinking everyday) (17.0%). A combination of alcohol expectancy (8.0%), influence of friends(4.0%), father's influence(2.0%), depression(2.0%), refusal self-efficacy (1.0%), personality of harm avoidance(1.0%), and monthly pocket money (2.0%) accounted for 38.6% of the variance in alcohol consumption behavior. Conclusion: From the results, we recommend to use the database that develops nursing intervention program for decreasing the alcohol consumption behavior including the influencing factors in university students.
