Purpose: The purpose of this study was to verify the educational effectiveness of the Objective structured clinical examination (OSCE) module development activities on nursing students in the areas of performance skill, knowledge, self-directed learning readiness, and problem solving ability for medication skill. Methods: This study was a nonequivalent control group non-synchronized post-test design. The subjects (N=47), who agreed to participate in this study, were assigned to either the experimental (n=24) or control group (n=23). The experimental group was trained with OSCE module development activities for four days. The control group was trained with a traditional demonstration and practice class for the same amount of time as the experimental group. Medication performance skill and knowledge tests and surveys were done to measure self-directed learning readiness, and learning satisfaction after the experimental treatments. Results: The experimental group which participated in the OSCE module development activities showed significantly higher performance skill, self-directed learning readiness, and problem solving ability for skin test and insulin medication than that of the control group of traditional education. Conclusion: It is recommended to use the OSCE module development activities for nursing students in nursing education-learning in order to improve nursing skills.

The rapidly growing global population increases the awareness of water, energy, and food security worldwide. The concept of Water, Energy, and Food nexus (hereafter, WEF nexus) has been widely introduced as a new resources management concept that integrate the water, energy, and food in a single management framework. Recently, WEF nexus analyzes not only the interconnections among the resources, but also considers the external factors (such as environment, climate change, policy, finance, etc) to enhance the resources sustainability by proper understanding of their relations. A nation-level resources management is quite complex task since multiple regions (e.g., watersheds, cities, and counties) with different characteristics are spatially interconnected and transfer the resources each other. This study proposes a multiple region WEF nexus simulation and transfer model. The model is equipped with three simulation modules, such as local nexus simulation module, regional resources transfer module, and optimal investment planning module. The model intends to determine an optimal capital investment plan (CIP), such as build-up of power plants, water/waste water treatment plants, farmland development and to determine W-E-F import/export decisions among areas. The objective is to maximize overall resources sustainability while minimize financial cost. For demonstration, the proposed model is applied to a semi-hypothetical study area with three different characterized cities. It is expected the model can be used as a decision support tool for a long-term resources management planning process.

Accurate and consistent characterization of defects in steam generator tubes (SGT) in nuclear power plants is one of the key issues in the field of nondestructive testing since the large number of signals to be analyzed in a time-limited in-service inspection causes a serious problem in practice. This paper presents an effective approach to this difficult task of automated classification of motorized rotating pancake coil (MRPC) eddy current flaw acquired from tube specimens with deliberated defects using deep neural networks (DNN). This approach consists of five steps, namely, the data acquisition using the MRPC probe in the tube, the signal preprocessing to make data more suitable for training DNN, the data augmentation for boosting a training performance, the training of DNN, and finally demonstration of the trained DNN for discriminating the axial and circumferential defects. The high performance obtained in this study shows that DNN is useful for classification of defects in tubes from the MRPC eddy current signals even though the number of signals is very large.

As the significance of knowledge convergence continues to grow, universities are making efforts to develop methods that promote multidisciplinary learning. To address this educational challenge, our paper applies network theory and text mining techniques to analyze university curricula and introduces a graphical syllabus rendering method. Visualizing the course curriculum provides a macro and structured perspective for individuals seeking alternative educational pathways within the existing system. By visualizing the relationships among courses, students can explore different combinations of courses with comprehensive search support. To illustrate our approach, we conduct a detailed demonstration using the syllabus database of Yonsei University. Through the application of our methods, we create visual course networks that reveal the underlying structure of the university curriculum. Our results yield insights into the interconnectedness of courses across various academic majors at Yonsei University. We present both macro visualizations, covering 18 academic majors, and visualizations for a few selected majors. Our analysis using Yonsei University's database not only showcases the value of our methodology but also serves as a practical example of how our approach can facilitate multidisciplinary learning.

Currently, breast cancer ranks third among women' s cancers, and as its incidence is increasing, the incidence age is also becoming lower. Therefore it is necessary to address breast cancer for women in their twenties. As there is no way presently to prevent breast cancer, it is imperative that women take available interventions against predisposing factors. It is thus advisable that women acquire the necessary skills to recognize their own health status. The purposes of this study were to identify the effects of education on breast self-examination (BSE) through supportive education among college women during the period from August 2000 to February 2001, and to attempt to design an effective BSE educational program. The first class was implemented through lectures, pamphlets, videotapes, breast palpation on cloths, demonstration and practice for identification of breast masses through palpation using breast model. Supportive education was implemented bimonthly to the experimental group, and effects of the education between experimental and control groups were compared 6 months later. The results of this study are summarized as follows: 1. The effects on supportive education of college women in BSE 1) The mean score of retained knowledge about breast cancer and BSE was 30.88 in the experimental group, and 29.66 in the control group and significantly greater in the experimental group than in the control group (t= -2.062, p= 0.041). 2) Frequency of BSE practice was significantly greater in the experimental group than in the control group($\chi^2=0.045$, p=0,012). 3) The mean accuracy score in BSE practice was 19.10 in the experimental group, and 18.29 in the control group; accuracy was higher in the experimental group than in the control(t= -2.035, p= 0.444). 4) The mean score of self-efficacy was 35.05 in the experimental group, and 31.22 in the control group. The experimental group mean score was higher(t=-3.016, p=0.003). 2. There was a statistically significant correlation between self-efficacy and accuracy of BSE(r=0.447, p=0.000), knowledge of breast cancer and BSE(r= 0.306, p=0.000) and frequency of BSE(r=0,259, p=0,002) but no significant correlation between knowledge of breast cancer and BSE and frequency of BSE (r=0.071, p=0.403). On the basis of this study, periodic supportive education can increase knowledge of breast cancer and BSE, frequency of BSE, accuracy of BSE and self-efficacy. Suggestions: 1. There is a need to compare the effects of individual programs to acquire BSE behaviors in the young. 2. Further research is needed to test the continuity of the effects of BSE education.

The purpose of the study is to evaluate the effectiveness and competence level of trainees of Cardiopulmonary resuscitation training targeted for nursing students. 70 nursing students of Y nursing college are recruited as subjects from Dec. 1st, 1998 through Dec. 8th. 1998. For the pre-test. demographic data related to CPR and knowledge of CPR were evaluated. For the post-test, the next week of pre-test, three difference groups of subjects were tested their knowledge of CPR. CPR training was designed by two components which were 90 mins lecture and demonstration by one professor and individual practice using two educational models with two professors. As the tool of measurement estimating pre or post knowledge of CPR. questionnaires were developed based on self-diagnosis questionnaires of American Heart Association(AHA). The questionnaires were multiple choices (50 questions) and open end questions regarding CPR process. Each multiple choices questions valued 2 points (Score varied min. 0 point to max 100 points.). Collected data were computerized and analyzed by SPSS-WIN. Frequency and percentage of each questions analyzed. The differences of the knowledge and competency level of subjects between pre and post test was analyses by paired t-test. The followings are research outcome. 1. In the pre-test, 95% of subjects answered that they already knew what CPR was. but only 82% described correctly what CPR was. 49% learned CPR before, and 80s5 of them learned at high school. 2. 37 questions scores increases, and 10 questions scores decreased. 3 questions didnt change their score. After getting training, ratio of 80% correct score significantly increased 4 times. 3. In post-test. knowledge level of trainees increased compared to that of pre-test. (t=-15.075, p=.000) 4. Competence level also increased (t=-14.86, p=.00). In result, after getting CPR training, most CPR knowledge increased except open the air tract, toddler CPR, and alternative behavior when the air tract is blocked. CPR training needs to extend the educational scope not only CPR lecture but also psychomotor skill practice. CPR trainees are in need of appropriate feedback as well as enough opportunities of skill practice.

Background : The objectives of this study were to examine patients' satisfaction with the DRG based payment method and its association with their awareness of the method, to examine patient reported changes in doctors' caring attitude, level of their out-of-pocket payments, providers' acceptance of patients' request for additional services after the program, and to examine changes in service utilization recorded in medical records. Method : One hundred-four patients who had cesarean sections before and after the demonstration program at two hospitals located in Seoul participated in the study. Patients were surveyed before discharges when their charges were finalized. Their medical records were reviewed as well to collect data for service utilization during hospital stays. The association between patients' satisfaction with the payment method and their awareness of the method was analyzed by ${\chi}^2$-test, and the significance of changes in providers' acceptance of patients' request for additional services and service utilization after the program were examined by ${\chi}^2$-test and t-test, respectively. Results : A large proportion of patients did not know of the DRG based payment method at the time of survey and a significantly larger proportion of patients who came to the hospitals with the knowledge satisfied with the method. About the same proportion of patients reported improvement and deterioration in doctors' caring attitude compare to the previous hospitalizations and a similar result was found concerning out-of-pocket payments. Providers' acceptance of patients' request for medication, PCA and painless delivery decreased significantly after the program whereas the acceptance for additional hospital days and laboratory and radiology tests did not. Length of stay, the numbers of days on antibiotics and antianemic medication, and the number of blood tests decreased significantly after the program, however, decreases in the rate of antianemic medication and the number of urine analyses were not statistically significant. Re-operation, in-hospital death, and complications were not observed before and after the program. Conclusion : The study findings indicated a need for better patient education and publicity about the newly introduced payment method to improve their satisfaction with the system. Other study findings concerning service utilization and quality of care indicators were consistent with the government funded evaluation studies.

노티싱은 교사가 교수학습 맥락에서 무엇에 주의를 기울이는지, 그것을 어떻게 해석하고 반응해야 하는지 결정하는 것을 의미한다. 노티싱을 분석하여 교육 설계 및 실행의 주체인 교사의 수업설계, 실행, 반성의 전반적 특성을 이해할 수 있으며 이는 교사 역량 강화를 위한 교사교육 설계의 기초자료로 활용할 수 있다. 이에 이 연구에서는 수업설계와 시연 후의 성찰 과정에서 나타나는 초등 예비교사의 노티싱 특성을 분석하였다. 이를 위하여 강원도 소재 교육대학에 재학 중인 초등 예비교사 106명이 온도에 따른 기체의 부피 변화 개념을 다루는 과학수업의 시연 후에 작성한 수업 성찰지를 분석하였다. '주체', '수업 단계', '주제', '초점', '견지'의 다섯 가지 차원으로 이루어진 노티싱 분석틀을 설계한 후 이를 활용하여 각 차원의 구성요소별 빈도와 비율을 도출하였다. 또한 '수업 단계'와 '주제'에 따른 '초점'의 빈도와 비율을 분석하였다. 연구 결과 '주체' 차원에서는 '교사와 학생'을 동시에 주목한 빈도가 가장 높았으며, '수업 단계' 차원에서는 '탐구 활동'의 빈도가 가장 높았다. '주제' 차원에서는 '수업전략에 따른 수업설계'가 가장 빈번하게 나타났으며 '초점' 차원에서는 수업의 목표이자 학생이 달성해야 할 역량을 특정하지 않은 경우가 가장 많았다. '견지' 차원에서는 '기술'이 가장 높은 빈도로 나타났다. '수업 단계'와 '주제'에 따라 '초점'이 어떻게 달라지는지 분석한 결과 차원의 구성요소별로 특징적인 초점이 나타난 것을 알 수 있었다. 연구 결과를 토대로 예비교사의 노티싱 특성이 교사교육의 설계 및 운영에 갖는 시사점을 논의하였다.

With the rapid development of nowadays technologies, the environment of product development is experiencing structural changes than ever. Manufacturers are put under never-experienced pressures to launch their products in the market both faster and less expensively than their competitors while continuously improving product quality These pressures have given birth to so-called, Concurrent Engineering which is a systematic approach to the integrated, concurrent design of products and their related processes, including manufacture and support. Most manufactiring companies now recognize the importance of concurrent engineering and put heavy emphasis on the research and impementation of concurrent engineering. However, with this fundamental change in the process of product development, designers rarely pay attention to this newly demanding process. Designers still stay in the middle of process, satisfying their roles in dealing with aesthetic points of product. Designers badly need to incorporate the concept of concurrent engineering to design to design process and to adapt to this new environment. With these backgrounds, the study sets the objective to understand the nature of concurrent engineering and explore the possibility of it's application to industrial design. Particularly this study focuses on how the concept of concurrent engineering can be applied from the stage of form development to prototyping. At first, background, objectives, and scope of the study are discussed as an introductory part. It is followed by reviewing theories of concurrent engineering such as definition, history, technologies, examples, state of art and so on. Subsequently industrial design is viewed in terms of concurrent engineering and problems in industrial design are identified. Base on the findinss of precedent part of study, new process of industrial design incorporating concurrent engineering is developed. For the demonstration of new process, a case study of design of palm-top printer is introduced. Case study shows how the sketch, and forms can be transformed into prototyping with the simultaneous cooperation with engineering and other related specialists. Finally the study in summarized and future studies are prospected.

Purpose: This study was conducted to identify the effects of newborn care education for fathers on their knowledge and confidence in newborn care at postpartum one month. Methods: A nonequivalent control group pretest posttest design was used. The participants were 53 first-time fathers of newborns, 27 in experimental group, and 26 in control group. They were recruited at the nursery of one municipal hospital in Seoul. For the experimental group, a 50-minute education on newborn care using video, verbal education, demonstration and practice were provided prior to discharge. Fathers' knowledge and confidence in newborn care and their satisfaction with the education program were measured at postpartum one month. Results: The fathers in the experimental group showed significantly higher knowledge (t= -4.51, p<.001), and confidence in newborn care (t= -2.29, p=.026) compared to the control group at postpartum one month. Fathers in the experimental group had a satisfaction score of $27.37{\pm}2.73$ immediately after the education, and $25.30{\pm}3.40$ at postpartum one month. Conclusion: Results indicate that newborn care education for first-time fathers is an effective method in enhancing the level of knowledge and confidence in newborn care. It can be used in the nursery department before discharge as a useful nursing intervention.
