남상희,김지연 한국생활과학회 2022 한국생활과학회지 Vol.31 No.5

This study aimed to examine the effect of problem-focused coping on subjective well-being and the moderating effects of awareness of positive (gains) or negative (losses) age-related changes among elderly people. Specifically, this study predicted that problem-focused coping would be positively related to subjective well-being (hypothesis 1) and that the awareness of positive (hypothesis 2) or negative (hypothesis 3) age-related changes negatively moderated the influence of problem-focused coping and subjective well-being. For this purpose, we conducted an online survey with 350 elderly participants. The results were as follows: First, problem-focused coping positively predicted subjective well-being; Second, awareness of positive age-related change mitigated the relationship between problem-focused coping and subjective well-being; However, the moderating effect of awareness of negative age-related change was not significant. Finally, the implications and limitations of this study were discussed. 본 연구의 목적은 노인을 대상으로 문제중심대처와 주관적 안녕감의 관계를 확인하고, 문제중심대처와 주관적 안녕감 사이에서 노화이득인식과 노화손실인식의 조절효과를 확인하는 것이다. 본 연구에서는 문제중심대처와 주관적 안녕감이 유의한 정적인 관계가 있을 것이며(가설 1), 두 변인 간의 관계가 노화이득인식과 노화손실인식에 의해 완화될 것이라고 예상하였다(가설 2, 가설 3). 이를 위해 350명의 노인을 대상으로 설문조사를 실시하였으며, 그 결과는 다음과 같다. 첫째, 문제중심대처는 주관적 안녕감을 정적으로 예측하였다. 둘째, 문제중심대처와 주관적 안녕감의 관계는 노화이득인식에 의해 약화되었다. 셋째, 문제중심대처와 주관적 안녕감 사이에서 노화손실인식은 유의한 조절효과를 갖지 못하였다. 마지막으로 본 연구의 의의와 한계를 논하였다.

Many physiological systems have complex phenomena. Thus, these complex phenomena are analysed by nonlinearly recently. Especially, the flow of capillary blood vessel has a nonlinear dynamic system. Thus, this study, we analyzed nonlinear characteristics of the flow of capillary blood vessel in physiological systems using chaotic tools(phase space reconstruction, correlation dimension, largest lyapunov exponent). And we injected glucose to rabbits in order to compare between stable state and unstable state. Experimental data have been acquired from examining 10 rabbits. The results of chaotic analysis showed chaotic behavior of rabbit's flow of cappilary blood vessel and the decreasement of largest lyapunov exponent and correlation dimension accordng to injection of glocose. And we also knew the chaotic behavior.

電算化 斷層撮影像에 關한 畵像 再構成法의 數理學的 考察

南尙熙,宋在寬,趙準錫 대구보건대학 1981 대구보건대학 論文集 Vol.5 No.-

The basic principle behind computed tomography is that the internal structure of an object can be reconstructed from multiple projections of the object. The mathematical methods is to produce an accruate cross-sectional display of the linear attenuation coeffidients of each element in the image matrix. This mathematical methods of image reconstruction are described : 1. Back-projection (Sumation method) 2. Iterative methods(Algebraic reconstruction tehnique) 3. Analytical methods (Fourier transformation) We will only attempt a pictorial explanation of the two popular analytic methods, which are two - dimensional fourier analysis and filtered back projection. The basic of fourier analysis is that any function of time or space can be represented by the sum of various projection data. This type of mathematical manipulation is easily and quickly processed in a computer. The reconstruction is a little more complex for a two-dimensional image such as a CT, but the basic principle is the same.

X線 回折에 의한 GaAs의 電子密度分布

南尙熙 대구보건대학 1986 대구보건대학 論文集 Vol.9 No.-

A X-ray study with CuKa was carried-out a sample of GaAs powder. Relative intensities of 14 line from the 111 to the 711 were masured and scale factor determined from S ∑ F_(r) = F^(o)_(c) exp(- B sin²8 / λ²). The temperature factors of individual ions were estimated by three dimensional difference Fourier synthesis. The factors obtained were B-(Ga) = 0.916 Ų_(s), B = 0.929 Ų for GaAs. Two sorts of peaks from the three dimensional difference Fourier synthesis in the directions of [100], [110] and [111] were found in △ ρ (x, y, z). One lies near (1/8, 1/8, 1/81, which is the midpoint of chemical bond between Ga and As. This peak Seems correspond to the covalent bond character. The other lies near (1/2, 1/2, 1/2), which is the position of anions in the NaCl structure with a cation at the origin. It seems like that this latter peak coincide with the ionic bond character.

방사선 영향에 대한 MOS소자에서의 전기적 특성

남상희 인제대학교 1993 仁濟論叢 Vol.9 No.1

전리방사선에 의한 MOS소자의 산화층내의 charge density의 변화를 TSC, TVS방법으로 조사하였다. 전리방사선의 조사되지 않은 시편에서 두개의 peak를 얻었으며, 두 peak의 활성화에너지는 저온의 peak가 0.7eV, 고온의 peak는 1.2eV였다. 이값은 Hickmott등이 구한 H+, 고온의 peak는 Na+ 이온임을 증명하는 것이다. 그러므로 전리방사선의 조사에 의한 MOS소자의 charge density는 이동성 이온임을 밝혀졌다. MOS소자의 산화층내의 trap의 분포는 Al-SiO2 계면이 Si-SiO2 계면보다 더 큰 활성화 에너지를 가지고 있으며, trap분포는 Si-SiO2 계면이 더 밀집되어 있다. 전리방사선의 조사선량을(Rhm)의 증가에 따른 최대전류의 증가는 heating rate(β)나 voltage sweep rate(α)의 증가와 유사하였으며, 이 결과는 열적, 전기적 자극의 변화와 일치한다는 것을 의미한다. This study is to investigate tha the electrical character of charge density within MOS capacitors growing oxide layer on N-type silicon by dry oxidation is charged by ionization radiation. When MOS capacitors are exposed to 57C0(5.4mCi) γ-ray, it induced space charge built up on the oxidized silicon surface layer. The space charge are able to drift out of the oxide layer under the action of a field and a region of space charge is created at the MOS interface. I wased the following experimental method ; Thermally Stimulated Current(TSC), Triangular Voltage Sweep(TVS) In TSC experiment, I know that TSC current was two current peak, and the lower temperature peak become bigger in proportion to H+ ions, and the higher temperature increased to Na+ions. I also discovered that Activation Energy was 0.7eV(H+) and 1.2eV(Na+) respectively, and that in the trap depth was almost like and was deeper Al-SiO2 that Si-SiO2. In proportion to the increase of the field :activation Energy(E) and Maximum current generated temperature(Tm) decreased which was the decrease of potential well of trap which positive ions went with H+ ions was influenced by the field, but Na+ions temperature. In TVS experiment, I observed that the trap depth Al-SiO2 was deeper than Si-SiO2 surface and was broader than Si-SiO2 in the trap distribution. Mobility was alike to that gained by Hickmott, Stagg. Mother observance I made was that ions was easily released from the trap by the strong field in the low temperature. I also discovered that the experiment value would well explained the relation of the change of the heating rate(β) and voltage sweep rate(α) was almost alike elevated ionization radiation.

南尙熙 대구보건대학 1983 대구보건대학 論文集 Vol.7 No.-

The measured Values of the Voc and Isc as a relative light intensity the spectral photo response made by using Vaccum-evaporated Cds-Cu₂S this film. The spectral photoresponse peak was observed at the wave length longer than the wave length corresponding to a band gap of Cds-Cu₂S. The spectral photo response compared to work which has been done based on the Cds-Cu₂S single crystal material.
