Purpose: The purpose of this study was to identify the effects of Problem-Based Learning on Academic Resilience, Learning Flow, and Academic Motivation in nursing students. Methods: Research design was a non-equivalent control group pretest-posttest design. The participants were 121 sophomore nursing students from two universities. They were divided into the Problem-Based Learning group (n=61) and Lecture-Based Learning group (n=60). The data were analyzed by Chi-square, paired t-test, and independent t-test. Results: In the PBL group, there was statistically significant improvement in Academic Resilience after intervention (pretest $3.88{\pm}.36$, posttest $4.00{\pm}.38$, p<.001). However, no statistically significant difference was found in the Lecture-Based Learning (LBL) group (pretest $3.86{\pm}.43$, posttest $3.93{\pm}.17$). In terms of Learning Flow, there was statistically significant improvement in the PBL group (pretest $3.31{\pm}.41$, posttest $3.51{\pm}.42$). However, no significant change was identified in the LBL group (pretest $3.45{\pm}.42$, posttest $3.48{\pm}.47$. Academic motivation was improved in the LBL group (pretest $3.32{\pm}.30$, posttest $3.46{\pm}.32$, p=.002) as well as in the PBL group (pretest $3.26{\pm}.23$, posttest $3.47{\pm}.21$, p<.001). Both results were statistically significant. Conclusion: These results suggest that Problem-Based Learning could be more effective for nursing students in improving their academic achievement. Further studies need to be investigated.

This study conducted to investigate the effects of Peer-Assisted Learning(PAL) applied to nursing education on self-directed learning ability, academic self-efficacy, and academic achievement of nursing students. The research design was a pre-post-post design with an inequality control group, and a total of 229 students from G University who agreed to participate in the study were included. After the completion of regular classes, the experimental group(N=117) was given a PAL program at least once a week for 10 weeks, and the control group(N=112) was given individual self-learning for 10 weeks. The collected data were analyzed using descriptive statistics, X2-test, and independent t-test using SPSS/WIN 21.0. As a result, self-directed learning ability(t=6.50, p<.001), academic self-efficacy(t=2.01, p=.046), and academic achievement(t=4.98, p<.001) were higher in the experimental group than in the control group. As the positive effect of peer learning on nursing students was confirmed through the results of this study, it can be used as useful basic data when designing extracurricular activities for nursing education.

This study was undertaken to compare the effectiveness of imparting education to nursing college students, using traditional teaching methods and action learning teaching methods. The target of the study was to measure nursing leadership, academic self-efficacy, and self-preservation of the students, and determine the effects of action learning method imparted 2 hours daily for 8 weeks, out of the 15-week study schedule. Ed. Notes: There is a lot of repetition, and the highlighted statement lacks clarity. I am unable to understand the study period. Does the author mean 2 hrs daily for 8 weeks? I have suggested the edits as per my understanding. Please review and revise appropriately, if required. Differences obtained between nursing leadership, academic self-efficacy, and self-leadership when comparing the experimental and control groups, were analyzed by independent sample t-test. Pre and post comparisons of the domains were analyzed with a paired t-test. The study results indicate significant differences in academic self-efficacy and self-preservation between experimental and control groups after application of the action learning teaching method, leadership in nursing as a lower area, confidence in academic self-efficiency, and self-control efficacy. Our results indicate that the recently emerged action-learning teaching is an effective method to apply in existing curriculums.

This study was a quasi-experimental design with a non-equivalent pre-post test that verified the effect of formative feedback practice on practice satisfaction, learning motivation and academic self efficacy for nursing students. 37 were assigned to an intervention group and 41 to a control group. Formative feedback practice was applied to intervention group and peer review smartphone videos was applied to control group. Data were analyzed using the SPSS/WIN 22.0 program. There was no significant difference in learning motivation between the groups, but there were a significant difference in practice satisfaction(t=-2.79, p=.007) and academic self efficacy(t=2.30, p=.024) between the pre-post scores of the experimental group. This is meaningful in that it is more effective to provide formative feedback practice than to provide peer review smartphone videos. Therefore, it is necessary to consider formative feedback practice for the acquisition of core fundamental nursing skills of nursing students.

드론의 시장규모가 커짐에 따라 초창기 군사 목적에서 현재 민간부문으로 확대되고 있다. 현재 드론은 실외에서 사용될 목적으로 제작된 것이 많으나 실내에서도 드론의 활용 여부가 증가할 것으로 예상된다. 본 연구에서는 실외에서만 사용 가능한 GPS를 대신하여 영상 촬영으로 획득한 이미지를 CNN으로 학습을 시켜 자율고도제어비행을 하도록 한다. 첫 번째로 수동 조작하는 드론에 IMU센서를 부착하여 획득한 고도 데이터를 표로 제시함으로써 GPS를 사용하지 않는 드론의 실내주행에서 일정한 고도 유지는 다소 무리가 있음을 보여준다. 두 번째로 드론의 수동 조작은 일정하지 않은 고도 때문에 CNN의 학습할 영상 획득이 어렵다. 일정한 고도의 영상 획득을 위한 실험용 높이 조절 Base를 제작하여 고도별 영상을 획득한다. 획득한 영상을 통해 얻은 이미지를 CNN 학습을 시킨 후, 학습에 사용되지 않은 이미지를 사용하여 고도 판별을 확인한다. 대조군으로 실내장소를 바꾸어 미리 학습된 CNN으로 고도 판별을 확인한다. 학습에 사용된 이미지의 환경(생명공학관)과 대조군(제 2 공학관)이 촬영된 장소의 환경요소의 차이로 오차가 발생한다. 오차는 실내 장소의 총 높이의 차이 및 서로 상이한 천장 구조물에 따른 것으로 사료되며 Data crop을 통해 획득한 이미지의 천정 부분을 제거하여 노이즈를 줄여 고도 판별의 정확도를 높일 수 있을 것으로 예상한다. 세 번째, CNN으로 학습을 통해 Model을 도출하여 자율 고도 제어 프로세스를 제시한다. 그리고 해당 프로세스를 이용한 자율고도제어 주행과 수동조작을 통한 주행에서의 Z축 가속도 데이터의 표준편차를 비교하여 본 연구의 실효성을 보여준다

인삼 성분이 학습 및 기억력 중진에 미치는 효과를 연구하기 위하여, 학습 및 기억력 저하를 유발하는 약물들에 대한 아답타겐 (상품명) 과 인삼 수 엑기스산의 효과를 관찰하였다. Ethylcholine aziridium ion(AF64A), scopolamine 및 morphine을 쥐 및 생쥐의 해마와 복강에 각 각 주입하여 학습 및 기억력 저하를 유발한 후 아답타겐을 경구 투여하여 학습 및 기억력에 미치는 효과를 수로시험을 통하여 측정하였다. 또한 인삼 수 엑기스산을 일주일 동안 복강 주사하여 각 효과를 수로시험을 통하여 측정하였다. 또한 인삼 수 엑기스산을 일주일동안 복강 주사하여 각종 신경계에 미치는 변화를 효소 활성도, 신경전달물질의 농도, 수용체 결합을 지표로 하여 살펴보았다. AF64A 투여군 중 플랫폼을 전혀 인지치 못한 군에 아답타겐을 투여시에는 투여 횟수에 따라 플랫폼을 인지하는 비율이 증가했다. 연습 후 일주일간 물을 투여한 대조군의 도달 시간에 큰 변화가 없음에 반해, 아답타겐을 투여시에는 3일 투여 후 최대 시간이 걸리고, 투여횟수가 증가할수록 점차 도달 시간이 단축되었다. 인공 뇌척수액 및 AF64A의 투여군에서 아답타겐을 5일간 투여한 경우 대조군보다 각각 3배 빠른 속도로 플랫폼을 기억하였다. 한편 scopola mine 투여시에는 아답타겐을 투여한 군이 투여하지 않은 군보다 약 3배 빨리 플랫폼에 도달하였으나 각 투여군의 매일의 도달 시간 차이에는 변화를 나타내지 않았다. 또한 4일 전에 아답타겐을 투여시에는 saline 및 merphine 투여시 약 1.4배 빨리 플랫폼을 인지하였다. 인삼 추출물을 7일 투여 했을 경우 선조체에서 도파민 합성 효소인 tyrosine hydroxylase 활성이 유의성 있게 증가했으며, 대사체인 DOPAC의 농도도 증가를 나타냈다. 그러나, 도파민, HVA및 대사율인 DOPAC/DA와 HVA/DA에는 변화를 보이지 않았다. 또한 선조체의 GABA농도는 약 66%로 낮아졌지만 AChE의 활성도는 변화가 없었다. 인삼 수 추출물을 2주일 투여시 선조체의 도파민 수용체의 특성변화는, D1 수용체의 친화력에는 변화가 없는 반면, 최대 결합 수용체 수는 약간 낮아졌고, D2 수용체의 경우 최대 결합 수용체수는 변화가 없었으나 친화력은 감소하였다. 또한 피질의 benzodiazipine수용체 결합 친화력에는 변화가 없는 반면 최대 결합 수용체 수는 약 15%의 증가를 나타내었고 연수의 benzodiazepine 및 피질의 GABA 수용체의 특성에는 에는 변화를 나타내지 않았다. 이상의 결과, AF64A, 아급성 scopolamine 및 급성 morphine꽈 투여로 학습능이 저하되고 아답타겐을 경구 투여시엔 저하된 학습능력 빛 기억력의 증가를 보였다. 또한 본 결과는 인삼성분 중에는 도파민 및 GABA신경계에 영향을 주는 성분이 있음을 제시하였다.

Havruta is the best teaching and learning method for developing the process of thinking, and it is a method of education centered on a range of student activities. This study examined the effects of adult learning nursing education using the Havruta learning method on the critical thinking disposition, learning commitment, and learning satisfaction. Data collection was carried out from September to December, 2017 in 96 second grade nursing college students attending a university in U city. The data were analyzed using descriptive statistics, ${\chi}^2-test$, t-test, and two-way repeated ANOVA using the SPSS WIN 23.0 program. The critical thinking disposition, learning commitment, and learning satisfaction were similar in the experimental group, who performed the adult nursing education using the Havruta learning method, and the control group. On the other hand, after the adult nursing education using the Havruta learning method, the critical thinking tendency (md=.14, p=.045), learning commitment (md=.27, p=.025), learning satisfaction (md=.30, p=.031) increased significantly. Therefore, adult nursing education using the Havruta learning method is an effective program to improve the critical thinking disposition, learning commitment, and learning satisfaction of nursing college students.
