이유희,문미경 한국문화융합학회 2024 문화와 융합 Vol.46 No.1

본 연구는 간호대학생의 가정폭력 노출 경험과 대인관계 유능성의 관계에서 자아존중감의 매개효과를파악하기 위한 서술적 조사연구이다. 본 연구는 I와 D광역시 2개의 간호대학에 재학 중인 만 20세 이상의 151명의 간호대학생으로 대상으로 온라인 설문조사하였다. 수집된 자료는 SPSS 21.0을 이용하여t-test, ANOVA, Pearson correlation coefficient, multiple regression으로 분석하였다. 매개효과 검증을 위해 Baron & Kenny(1986)의 절차에 의한 매개효과 증명과 더불어 Sobel Test를 실시하였다. 연구 결과 가정폭력 노출 경험과 대인관계 유능성의 관계에서 자아존중감이 완전매개한다는 것을 알수 있었다. 이러한 결과를 바탕으로 가정폭력 노출 경험이 있는 간호대학생의 대인관계 유능성 향상을위해 자아존중감을 높이는 중재프로그램이 필요하겠다. The purpose of this study was to identify the mediation effect of self-esteem between experience of exposure to family violence and interpersonal competence. The study involved 151 nursing students aged 20 and older. The data were analyzed by t-test, ANOVA with Scheffé test, Pearson’s correlation coefficients, and multiple regression analysis. Mediating effect of self-esteem was examined by the verification process suggested by Baron and Kenny. the Significance of mediation effect was verified by Sobel test. Interpersonal competence of nursing students showed a significantly negative correlation with experience of exposure to family violence and positive correlation with self-esteem. The influences of experience of exposure to family violence on interpersonal competence among nursing students was completely mediated by self-esteem. The program of interpersonal competence on nursing students should include the consideration about experience of exposure to family violence.

Milling을 이용한 ZnS:Cu,Cl 형광체의 결정 상 변화 및 EL 특성 연구

이유희,한상도,박윤봉 충남대학교 기초과학연구소 2005 忠南科學硏究誌 Vol.32 No.1

A Green phosphor(ZnS:Cu,Cl) was manufactured by solid-liquid reaction for ELD (Electroluminescence Display). The effect of artificial crystal defect on phosphor surface for the ZnS phase conversion and luminescence efficiency have been studied. It was found that ZnS:Cu,Cl could convert to cubic phase more easily due to the formation of artificial crystal defect on 1st fired phosphor by milling process, resulting in improvement of luminescence of phosphor under the driven EL condition. We found out an optimized milling condition through considering effect of each milling conditions such as milling time and rate on defect. Also we determined relationship between EL emission luminescence and driving conditions. A efficient improvement above 50% was observed in electroluminescence by the artificial defect on ZnS:Cu,Cl phosphors compared to crude phosphor.

이유희,최유진,최정옥 한국융합학회 2017 한국융합학회논문지 Vol.8 No.1

본 연구는 다중이용시설등의 실내공기질 관리법에 의해 시행되고 있는 의료기관의 실내공기질을 조사하 여 관리실태를 파악하고 장소에 따라 나타나는 차이를 융합적으로 분석하여 세부적 관리방안을 제시하기 위한 목적 으로 실시하였다. 부산광역시에 소재하는 의료기관 153개를 대상으로 직접 방문조사하여 미세먼지(PM10), 이산화탄 소(CO2), 포름알데하이드(HCHO), 총부유세균(TAB), 일산화탄소(CO)를 조사하였다. 연구결과를 살펴보면, 전체적 산출평균은 유지기준을 초과하지 않았으나, 항목별 최대값은 PM10이 91%, CO2가 97%, HCHO가 96%, TAB가 99%에 해당하여 기준에 매우 근접하는 것을 확인하였다. 또한, 유동인구와 관련하여 측정 장소를 다르게 하여 측정 한 결과는 각 특징에 따라 서로 다른 값을 보였다. PM10은 로비에서 61.80±9.66 ㎍/㎡, CO2는 복도에서 632.08±112.86 ppm으로 가장 높게 나타났다. 반면, HCHO는 입원실이 21.88±17.03 ㎍/㎡으로 가장 높은 것으로 나타났다. TAB와 CO는 복도에서 각각 634.08±46.41 CFU/㎡와 0.81±0.66 ppm으로 가장 높았다. 5곳의 측정결과 유의한 차이는 없었다. 결과적으로 의료기관 실내공기는 불특정 다수인들이 수시로 출입가능하며 환자들이 주로 생활하는 시설적 특징을 충분히 고려하여 보다 세밀하고 체계적인 관리가 이루어져야 한다. The purpose of this study was to investigate the indoor air quality of medical institutions and to present the detailed management plan by analyzing the actual situation of management and analyzing the difference according to the place in a convergent. (PM10), carbon dioxide (CO2), formaldehyde (HCHO), total aerobic bacteria (TAB) and carbon monoxide (CO) were investigated in 153 hospitals in Busan. As a result, The overall output average did not exceed the maintenance criteria, but the maximum values for each item were 91% for PM10, 97% for CO2, 96% for HCHO, and 99% for bioaesol. And It is confirmed that this is very close to the standard. In addition, the results of each place showed different values according to each feature, but there was no significant difference in the results of five measurements. In conclusion, Indoor air in medical institution considering the characteristics should be performed systematic and detailed management of ventilation facilities and energy problems.

양자화레벨의 변화에 따른 역전파알고리즘

이유희,이병호 漢陽大學校 工學技術硏究所 1999 工學技術論文集 Vol.8 No.1

본 논문은 다층퍼셉트론에서의 양자화 기법의 효과를 연구 하였다. 양자화 기법은 performance를 다소 감소하지만 연결강도치를 효과적으로 압축할수 있기 때문에 실용성이 증가되고 실제 VLSI 설계시 회로의 단순화와 비용등을 줄일 수 있다. 또한 양자화 기법 사용시 가장 중요한 요소인 양자화 레벨을 조사하여 주어진 네트워크에서 적절한 레벨을 구하였고 제안한 방법의 효용성을 입증하기 위하여 여러 가지 함수 발생기에 적용하고 각각의 경우의 양자화 레벨을 조사하여 양자화 레벨의 변화시 생기는 결과의 차이를 고찰하였다. In this paper, we propose a quantization method for training multilayer perceptron networks. Although the quantization method may tend to slightly deteriorate the performance, it may reduce a chip size for hardware implementation and cost in application. The loaming method used here is equal to the backpropagation learning method used in multilayer perceptrons. In our method, we investigate the regurred number of bits and approximate the weight vector for each perceptron. In addition, the proposed method employs a network structure that consists of two hidden layers. Due to the two hidden layers, it may require many computations. However, experimental results show that we can achieve satisfactory results. We apply various functions to our network to show the validity of the proposed network. Network variations due to quantization levels are also investigated.

오르간의 구조와 설명

[오르간]은 악기중의 왕이라고 한다. 이는 아마도 [오르간]이 많은 악기의 음색을 동시에 낼 수 있으며 폭 넓은 음량을 갖고 있기 때문일 것이다. 그러기에 19세기 낭만과 작곡가인 Widor와 Viern이 "Organ Symphony"까지 쓴 바가 있다.

A strongly cytotoxic fraction (Fc-2, ED_50=0.0003㎍/㎖) against L1210 cell was obtained from the root, seed and fruit of Trichosanthes kirilowii, Administration of Fc-2 prolonged the life span of the BDF1 mice bearing L1210 and the ICR mice bearing S-180 by 135% and 130%, respectively. The Fc-2 affected L1210 cells were enlarged in their diameters two or three times in comparison with the untreated ones. When 20㎎/㎏ of Fc-2 was administered, intraperitoneally, all the mice were killed.
