This study was done to develop self - directed learning modules related to asepsis and elimination including urine and stool for Fundamentals in Nursing practice education contents and to measure the effectiveness of those modules. The subjects of this study were 96 sophomore students in the nursing college. Self-directed learning modules were developed by the researcher on the basis of the Lippincott Learning System of Kruger (1986) and Modules for Basic Nursing Care of Ellis (1992). Videotape was editted by using videotape made by the Lippincott Company and Film strip made by the Trainex Company with Korean dubbing. Self-directed learning was done for one week with the asepsis module and two weeks with the elimination modules after confirming the requiered level of knowledge acquisition through pre-test. For measuring proficiency in self-directed learning, a written test for cognitive domain, a sufficiency test for psychomotor domain, and a confidnece examination for affective domain were given. The data were analyzed using descritive statistics, and Pearson correlation coefficient using a SPSS-PC program. The results are summarized as follows: 1. Sufficiency test and confidence examination grades showed high levels in both asepsis and elimination. 2. Written test grades showed a high level in asepsis and elimination of urine but showed a medium level in eliminationin of stool. 3. Grades of sufficiency and confidence in asepsis and elimination practice were statistically significant with a moderate positive correlation (r=0.4- 0.5, p<0.001). 4. Grades of sufficiency and written tests in asepsis and elimination practice also were statistically significant with a moderate positive correlation (r=0.5-0.7, p<0.001). 5. Students showed relatively high contentment with the self-directed learning modules themselves but revealed relatively low contentment with video program and the self-directed learning process. In conclusion, this study disclosed that proficiency levels in cognitive, affective, and psychomotor domains were high when asepsis and elimination modules were applied. Also students showed high satisfaction with the modules themselves, but didn't show high contentment with the video programs. In considering low contentment with the self-directed learning process, it is estimated the students had experienced some difficulties about using self-directed learning modules because this was their first exposure to the self-directed learning module and they were already accustomed to the demonstration-practice method.

The analysis of digital microscopy images plays a vital role in computer-aided diagnosis (CAD) and prognosis. The main purpose of this paper is to develop a machine learning technique to predict the histological grades in prostate biopsy. To perform a multiclass classification, an AI-based deep learning algorithm, a multichannel convolutional neural network (MCCNN) was developed by connecting layers with artificial neurons inspired by the human brain system. The histological grades that were used for the analysis are benign, grade 3, grade 4, and grade 5. The proposed approach aims to classify multiple patterns of images extracted from the whole slide image (WSI) of a prostate biopsy based on the Gleason grading system. The Multichannel Convolution Neural Network (MCCNN) model takes three input channels (Red, Green, and Blue) to extract the computational features from each channel and concatenate them for multiclass classification. Stain normalization was carried out for each histological grade to standardize the intensity and contrast level in the image. The proposed model has been trained, validated, and tested with the histopathological images and has achieved an average accuracy of 96.4%, 94.6%, and 95.1%, respectively.

목 적 : 신초음파검사는 수신증의 발견을 향상 시켰지만, 수신증의 임상 경과 및 치료에 대해서는 많은 이견이 있다. 이에 저자들은 수신증의 정도에 따른 환아들의 임상적 특징을 연구하였다. 방 법 : 1998년 4월부터 2007년 12월까지 신초음파검사에서 수신증이 발견된 총 367명의 환아들 중에 추적 관찰된 207명을 대상으로 후향적으로 조사하였다. 신우전후직경에 따라 대상을 grade 1-4까지 분류하고, 분석을 위해 이를 다시 mild 군 및 severe 군으로 나누었다. 결 과 : 추적기간 동안 요로감염은 207명 중 91명(44%)의 환아에서 총 128회 발생하였고, 수신증 정도에 따라서는 grade 1이 89명 중 35명(39.3%), grade 2는 88명 중 41명(46.5%), grade 3은 22명 중 11명(50%), grade 4는 8명 중 4명(50%)으로 요로감염의 발생 유무에 대해서는 mild 군과 severe 군 사이에 유의한 차이는 없었다. 그러나 요로감염의 누적 빈도 및 년당 발생한 요로감염의 횟수를 비교 해볼 때 severe 군이 mild 군보다 유의하게 높았다(P=0.041). Mild 군은 175명 중 103명(58%)이 완해를 보여 28명 중 3명(10.7%)의 완해를 보였다(P<0.001). 또한 산전초음파에서 수신증의 발견될 확률은 심한 신우전후직경을 나타낸 환아에서 더 높았다(P<0.001). 결 론 : 저자들은 수신증의 정도가 심할수록 자연완해는 더 적게 일어나며, 요로감염은 더 빈번하게 발생하는 것을 알게 되었다. 따라서 수신증을 가진 환아에 대해 신장 예후를 증진시키기 위하여 예방적 항생제 등의 치료 지침의 확립이 필요하다.

초등수학에서 조작교구를 활용한 수업은 오늘날 수학교육에서 강조하고 있는 활동과 조작, 구성에 부합하는 다양한 요소를 포함한다. 초등수학에서 조작교구의 활용이 강조되는 이유는, 굳이 Piaget의 발달단계이론을 인용하여 초등학생들이 구체적 조작기에 놓여 있다는 사실을 들지 않더라도 초등학생들을 대상으로 한 수학 수업의 핵심이 구체와 추상 사이의 연결고리를 형성하는데 있으며, 그 대표적인 수업 방안이 조작교구를 활용한 수업에 있기 때문이다. 본 연구는 선행연구를 통해 검토된 조작교구에 대한 논의에서부터 시작하여 이로부터 조작교구에 대한 연구의 필요성을 이끌어내고, 특히 초등학교 수학수업에 활용 가능한 다양한 조작교구를 제안하기 위해 호주에서 개발되어 적용 중인 'Maths With Attitude' 교구(3-4학년, 대수와 패턴 영역) 프로그램을 분석한다. 또한 이러한 조작교구의 분석과 함께 이들 가운데 우리나라 초등수학수업에서 활용할 수 있는 조작교구와 내용들을 선별하여, 초등학교 3학년과 5학년 수학수업에 실제로 적용해봄으로써 'Maths With Attitude' 교구 프로그램의 다양한 활용 가치를 탐색하는데 그 목적을 두고 있다.

Purpose. The purpose of this study is to investigate how professional self-concept and ego-resilience of nursing students affect their clinical competence. Methods. This study conducted a structured-questionnaire survey with 143 nursing students to look into their professional self-concept, ego-resilience and clinical competence. Results. According to the study result, professional self-concept scored 2.85 on average out of 4 points, ego-resilience 3.61 on average, and clinical competence 3.48 on average. It was found that clinical competence had significantly positive correlations with professional self-concept (r=.58, p<.01) and ego-resilience (r=.44, p<.01). According to regression analysis, the factors affecting clinical competence were professional self-concept, ego-resilience, and academic grades in order, and explanatory power was 39.5%. Conclusions. Given the above results, in order to improve clinical competence of nursing students, nursing educational institutes need to find an educational plan which can contribute to increasing professional self-concept, ego-resilience, and academic grades.
