원자로 압력용기 저합금강들은 원자로 가동 중 중성자 조사에 의해 재질열화 (material degradation)가 발생한다. 그러므로 계속적인 재질열화의 평가는 발전소의 수명을 예측, 평가하기 위해서 매우 중요하다. 그러나 표준시편을 이용한 인장시험, 충격시험 및 파괴인성 시험법 등은 조사시편의 크기 및 수량에 제한이 따르고, 높은 방사능으로 인해 시험편의 취급에도 제약을 받게 된다. 따라서 소형시편을 이용한 재료의 손상평가기술의 필요성이 부각되었고, 소형펀치시험(small punch test, SP test)은 그 중 하나의 유용한 시험 방법이다.(중략)

The purpose of the study is to investigate the effects of community-based SSI programs (SSI-COMM) regarding "fine dust" on promoting middle school students' understanding of community issues and their character and values as citizens. SSI-COMM on fine dust was implemented in 4 middle schools located in Seoul, and 151 7th graders participated in the program lasting over 8 weeks. Data was collected through two questionnaires (i.e. students' understanding of issues, and character and values as citizens) and individual interviews with selected students. Results indicated that there were statistically significant increases in their understanding of fine dust issue after the program. In addition, the program significantly contributed to enhancing students' character and values, especially in the domains of social and moral compassion and socioscientific accountability. Student interviews revealed that they became more aware of the local community problems caused by fine dusts and started to consider what efforts should be made to solve them. They also felt individual responsibility for the occurrence of fine dust, and the need for participation and practice of community activities for vulnerable groups in affected areas.

Chosun regime, when it replaced the predecessor of Koryo, had to create political ideological system for new integration of the people. The new system, based on Confucianism, replaced religious values of Buddhism with educational ones. In this educational-ideological system, educational objects were mostly limited in character education's. Its goal was 'restoration of good nature'. For the principal agent of educational process, teacher had the initiative. These traits of educational system can be understood as an 'nature-unfolding perspective' or 'formal discipline perspective'. Moreover, the idea of 'teacher shall be served like prince' seems to be ground of political authoritarianism. In this respects, political traits of traditional education system can be restraining elements for developing independent individuality and free citizenship among Korean people. However, traditional teacher was not only authoritarian trainer. As 'a follower of truth and good', he was equal to his disciples. Teacher learned by teaching them. Students could be colleagues of their teacher. And the main traits of traditional education, focusing character development and community consciousness, are still important, in particular, to modern Korean educational and societal environment wanting in humane and participating citizenship.

ADI는 우수한 기계적 성질과 경제성을 바탕으로 80년내 들어 중요한 공업소재의 하나가 되었다. 성공적인 ADI 개발에 중요시 되는 요소로는 오스테나이트화 온도와 시간, 오스템퍼링 온도와 시간, 합금원소, 주물의 질 등이다. 온도와 시간은 ADI의 성능과 매우 밀접한 관계가 있으므로 엄격한 제어가 필요하다. 양질의 주물만이 양질의 ADI을 생산할 수 있으므로 열처리 전 주물의 질에 대한 관리가 필요하다. ADI의 우수한 성능으로는 고강도, 고연성 및 고인성, 내피로성, 내마모성 등이 있다. ADI의 성능을 이용하여 응용될 수 있는 분야는 기어 및 자동차 부품등의 단조강철 대체품과 주조성 및 가공성 등을 이용한 일반 공업제품에 이르기까지 다양하다. 경제적 측면에서의 ADI의 잇점은 생산에너지 및 가공비의 절감 등이다. 새 공업 소재로서의 ADI의 전망은 기술적, 경제적 측면에서 보강되어야 할 사항이 있으나, 이의 최대 장점인 우수한 강도 및 연성, 내 피로성, 파괴인성의 조합적인 기계적 성질과 강철 단조품에 대한 경제성, 주조가 부여하는 부품설계상의 융통성을 바탕으로 대단히 밝다고 할 수 있다.

Background: The recent trend of an increasing number of patients with acute cardiogenic shock or chronic congestive heart failure following myocardial infarction, as well as the considerable number who can not be weaned from cardiopulmonary bypass after open heart surgery, call for immediate efforts to develop affordable ventricular assist devices that are suitable for the Korean physique. Recently, a pneumatic pulsatile ventricular assist device (VAD), named DKUH-75, has been developed by the Department of Biomedical Engineering, in collaboration with the Department of Thoracic and Cardiovascular Surgery of Dankook University College of Medicine. The feasibility of the DKUH-75 VAD was evaluated on the bases of common hemodynamic variables and echocardiographic measurements in pigs, which are subjected to an acute cardiogenic shock state following myocardial infarction, using a novel coronary artery ligation method employing the ischemic preconditioning concept. Material and Method: Acute cardiogenic shock was induced in 10 Yorkshire Landrace Duroc strain pigs by ligating the left anterior descending coronary artery via an ischemic preconditioning process. The hemodynamic variables were monitored, with epicardial echocardiographic measurements performed before and one hour after the ligation. The DKUH-75 VAD was implanted into 5 pigs one hour after the onset of the shock. The hemodynamic variables and echocardiographic measurements were taken one hour after installation of the VAD. Result: The systolic, diastolic and mean systemic arterial pressures were significantly decreased in all the experimental animals one hour after the ligation. The systolic, diastolic and mean pulmonary arterial pressures were increased (Eds note: this completely contradicts the preceding statement? However, if you mean the non-experimental animals this should be stated?). The left ventricular end diastolic pressure (LVEDP) was increased, but the cardiac index decreased, An increase in the left ventricular end systolic dimension and decreases in the fractional shortening and ejection fraction were observed all animals one hour after the coronary artery ligation. In all 5 of the VAD implanted pigs, the systolic and mean systemic arterial pressures were increased, and the pulmonary arterial pressures decreased one hour after the implantation; the LVEDP decreased, but the cardiac index was significantly increased, In the echocardiographic measurements, the left ventricular end systolic dimension decreased after the implantation of the VAD, but the fractional shortening and ejection fraction significantly increased. Conclusion: Significant improvements in the hemodynamic variables and echocardiographic measurements were observed in the 5 VAD implanted animals one hour after installation, which had been subjected to an acute cardiogenic shock state by ligation of the coronary artery, indicating that the DKUH-75 VAD could help in the recovery of the myocardial function. This suggests that the DKUH-75 VAD is feasible in the short term in relation to an acute cardiogenic shock state due to myocardial infarction.

This study examined the factors affecting clinical practice adaptation to provide basic data for the improvement of clinical practice adaptation for the first year of clinical practice. The subjects were 153 nursing students and medical students in G-do. Data were collected from April 1 to April 30, 2019, and analyzed using a t-test, ANOVA, Pearson correlation coefficient, and multiple regression using IBM SPSS WIN/21.0. The mean of college adjustment, character, interpersonal competence, communicative competence, and clinical practice adaptation was 3.37 points, 3.82, 3.61, 3.56, and 3.54, respectively. Clinical practice adaptation was related to college adjustment, character, interpersonal competence, and communicative competence (p<.001). The most influential factor in clinical practice was interpersonal competence (β=.502, p<.001), followed by department adaptation (β=-.215, p<.001) and college adjustment (β=.174, p=.010), respectively. The explanatory power was 41.1% (F=34.11, p<.001). Therefore, a way to improve interpersonal competence is needed to advance clinical practice adaptation. In the character building program for adjustment to college life, systematic education is needed, including the opportunity to think about and understand oneself, continuous meeting to understand and accept others. In addition, repeated communication training to improve interpersonal competence is needed.
