吳世旭,朴春根,全泰玉,全哲昊,周原植,李圭用 東亞大學校 大學院 1978 大學院論文集 Vol.2 No.-
Aluminizing-treated structural steel is excellent in high temperature oxidation resistance, wear resistance and corrosion resistance. So, it has been widely used for the machine parts which have required such properties. However it is difficult to find out any study result of the notched influence on the aluminizing-treated materials and the second diffusion materials. In this investigation the low carbon steel plates with with V-notches were coated with aluminum and made into second diffusion. With these specimcns the bending fatigue strength and fatigue life were observed and also crack propagation of alloy layer was investigated. The results obtained are as follows: 1) On the smoothed specimens a fatigue limit of aluminizing material was lower than the one of raw material, but it was more increased than the one of heat treatment material, and the fatigue limit of second diffusion material was lowest. 2) On the V-notched specimens a fatigue limit of aluminizing material was higher with 44% increase ratio than the one of raw material and with 63% increase ratio than the one of heat treatment material, and the rate of increase became lower increase ratio in a fatigue limit comparing to aluminzing material, with no influence of notch radius. 3) According as the notch radius became smaller, the fatigue limit became. higher on the raw material, it was same on th aluminizing material and lowest on the second diffusion material. 4) Crack initiation period was 0.04% below of fatigue crack life and the full growth period of crack propagation at alloy layer was 0.1%. The crack propagation from alloy layer to matrix was 16% of the fatigue crack life. This means that the crack propagation rate at alloy layer was very fast but the crack delay at the boundary of both was so long. 5) Crack propagation grows through defects, inclusion, peeling and previous boundary.

Background: Superior colliculus is a part of midbrain, and participates in the visual reflexes, It receives afferent fibers from optic nerve, visual cortex, and spinotectal tract. After optic deprivation, the microscopic structure of the superior colliculus changed. Calcium-binding proteins (CBPs) Play an important role in the neuronal protection, differentiation and reorganization of the central nervous system, Objectives and Methods: The effects of neonatal retinal deafferentation on a CBPs, calbindm D-28k (CB), Parvalbumin (PB) and calretimn (CR), and the existence of colocalization between the CBPs were examined immunohistochemically in the rat superior colliculus. Results: On the experimental (contralateral to enucleation) side of superior colliculus, the number of CB-immunoreactive (IR) cells was reduced (77.4% compared to control), but not fibers. The number of PB-IR neurons and fibers was also reduced on the experimental side (88.5% compared to control), In the other hand, the CR-IR cells were dramatically increased (642% compared to control), but CR-IR fibers were markedly decreased on the experimental side. The colocalization between CB-CR and PV-CR was rarely observed in the superior colliculus Conclusion: These results suggest that the changes of retinotectal projection may alter the expressional pattern of CBPs in different manners; relatively stable in CB- and PV-IR neurons and plastic in CR-IR neurons.

Ok Jae Koo,Hyun Ju Oh,Byeong Chun Lee 한국수정란이식학회 2015 한국동물생명공학회지 Vol.30 No.4
Xenotransplantation of pig islet regarded as a good alternative to allotransplantation. However, cellular death mediated by hypoxia-reoxygenation injury after transplantation disturb success of this technique. In the present study, we produce transgenic pig expressing human heme oxygenase 1 (HO1) genes to overcome cellular death for improving efficiency of islet xenotransplantation. Particularly, Korean miniature pig breed, Micro-Pig, was used in the present study. Somatic cell nuclear transfer (SCNT) technique was used to produce the HO1 transgenic pig. Six alive transgenic piglets were produced and all the transgenic pigs were founded to have transgene in their genomic DNA and the gene was expressed in all tested organs. Also, in vitro cultured fibroblasts derived from the HO1 transgenic pig showed low reactive oxygen species level, improved cell viability and reduced apoptosis level

본 연구는 진료기록에 대한 일반인의 인식과 태도를 오픈노트(Open Notes)운동을 중심으로 알아보고, 우리나라 임상진료현장에서 오픈노트제도의 도입 가능성을 확인하는 것을 목적으로 한다. 연구 결과를 요약하면 다음과 같다. 일반인들은 주로 인터넷을 통해 건강정보를 얻고 있으며, 병원의 진료정보와 관련하여서는 보험회사에 제출하기 위한 진료비관련 기록을 주로 이용하였다. 또한 진료기록에 대해서는 의사나 병원이 위조 혹은 변조할 가능성이 있다고 인식하고 있었으며, 대부분의 응답자가 진료기록을 언제든 확인할 수 있다면 병원이나 의사에 대해 더 신뢰할 수 있다고 응답하였다. 한편 오픈노트 운동에 대해서는 대부분 좋은 아이디어라고 생각하고, 우리나라에서도 오픈노트제도가 시행되어야 한다는데 동의하였으며, 오픈노트제도가 시행된다면 참여하겠다고 응답하였다. 결론적으로, 진료기록의 투명성을 추구하는 오픈노트제도의 도입은 의사-환자 간 신뢰에 기여하여, 의사-환자 간 커뮤니케이션에도 긍정적인 영향을 기대할 수 있을 것이다. The purpose of this study was to investigate general population`s awareness and attitudes toward medical records and an `Open Notes` system which allows the general public to access their medical records anytime on the hospital website. This study also examines the possibility of making the `Open Notes` system available to Korean medical community and the general public. The results of this study shows that the general population usually used internet for health information. They obtained their medical records from the hospital mostly for the purpose of submitting to insurance company. They also believed that medical records that hospital and doctors provided might be forged or falsified. The majority of them responded that they could trust their doctors and hospitals more if they could have access to their own medical records anytime. Most of the respondents agreed that the Open Notes system would be beneficial for the general public and that it should be implemented in Korea. And they would be willing to participate in the Open Notes system if it is introduced In conclusion, if the Open Notes system which emphasizes transparency in medical records is introduced, it could enhance the trust between doctor and patient. The trust doctor-patient relation would make patients more likely to comply and be satisfied with doctors.

The purpose of this study was to examine the state of smoking among adolescents and their smoking-related oral health knowledge. The subjects in this study were the teens who were selected by convenience sampling from among the students who were in their first, second and third years in four different middle schools in the city of Iksan, North Jeolla Province. A self-administered survey was conducted from June 14 to July 12, 2011, and the answer sheets from 1,219 respondents were selected for analysis. The collected data were analyzed by the statistical package 12.0, and the findings of the study were as follows: 1. The smoker students accounted for 10.6 percent. The boys and girls who smoked respectively represented 16.0 and 5.4 percent. 2. As for the period of smoking, the largest group that accounted for 51.6 percent smoked for less than a year. Concerning the amount of daily smoking, the greatest group that accounted for 91.9 percent smoked less than 10 cigarettes. As to the motivation of smoking, the biggest group that represented 52.8 percent started to smoke out of curiosity. 3. Regarding smoking-related oral health knowledge, they got a mean of 0.85. Their scores in knowledge of oral malodor(0.95), oral cavity cancer(0.94) and periodontal diseases(0.93) were above the average, and their scores in knowledge of dental caries(0.70) and blunting of taste(0.77) were below the average. 4. The seventh graders got the best score of 5.28 in smoking-related oral health knowledge(p<0.01), and the students who were more satisfied with their life had a better oral health knowledge(p<0.05). 5. The senior students were more dependent on nicotine(p<0.01), and the number of smoking days(ß=0.407, p<0.001) and the period of smoking(ß=0.235, p<0.01) affected their nicotine dependence.

교대근무 간호사와 비교대근무 간호사의 공감수준이 삶의 만족도와 직무만족도에 미치는 영향
천경주(Kyung-Ju Chun),최주희(Ju-Hee Choi),김유리(Yoo-Ri Kim),이상옥(Sang-Ok Lee),장철훈(Chulhun L. Chang),김성수(Sung-Soo Kim) 한국콘텐츠학회 2017 한국콘텐츠학회논문지 Vol.17 No.3
본 연구의 목적은 간호사들의 공감수준을 측정하고, 공감수준이 그들의 삶의 만족도와 직무만족도에 미치는 영향을 알아보는 것이다. 공감수준, 삶의 만족도 그리고 직무만족도의 세 가지 요인들로 구성된 설문지를 부산지역 소재 병원에서 근무하는 간호사 150명에게 실시하였다. 간호사는 근무형태에 따라 교대근무 간호사와 비교대근무 간호사로 구분하여, 총 150개 중 144개의 설문지를 사용하여 IBM SPSS Statistics 21로 분석하였다. 교대근무 간호사는 공감수준이 높을수록 직무만족도가 높았고, 비교대근무 간호사는 공감수준이 높을수록 삶의 만족도가 높았다. 흥미롭게도, 공감수준은 교대근무 간호사의 직무만족도에 긍정적인 영향을 미쳤고(β=.282, p=.006), 비교대근무 간호사에게는 삶의 만족도에 긍정적인 영향을 미쳤다(β=.252, p=.048). 본 연구 결과, 간호사의 공감수준은 간호사의 삶의 만족도와 직무 만족도에 긍정적으로 영향을 주었다. 간호사의 공감 부족은 환자와의 갈등을 일으킨다는 사실에서 보듯이, 간호사의 직무수행을 향상시키기 위해서는 간호사의 삶의 만족도와 직무만족도에 있어 공감의 중요한 역할을 이해하려는 새로운 관점이 필요하다. The purpose of study is to measure nurses’ empathy levels and to examine the effects of their empathy levels on their life and job satisfaction. The questionnaire was administrated to 150 nurses working in hospitals in Busan. The questionnaire consists of three factors : empathy level, life satisfaction, and job satisfaction. Nurses are classed into two : shift work nurse and non-shift work nurse by their work type. 144 out of 150 questionnaires were used for the analysis with IBM SPSS Statistics 21. The shift work nurses with higher empathy levels showed higher job satisfaction. The non-shift work nurses with higher empathy level revealed higher life satisfaction. Interestingly, while empathy level had positive effects on shift work nurses’ job satisfaction(β=.282, p=.006), it also had impact on non-shift work nurses’ life satisfaction positively(β=.252, p=.048). As results show, nurses’ life and job satisfaction were positively related to their empathy levels. Given the fact that lack of nurses’ empathy often lead to conflicts with patients, in order to improve nurses’ job performance, we need a new perspective of understanding the important role of empathy in nurses’ job satisfaction and life satisfaction.
