Purpose: While clinical practice is crucial for nursing students to acquire the skills needed to provide professional, high-quality nursing care, further studies on improving undergraduate nursing programs are needed to provide a supportive clinical learning environment for student nurses. This study aimed to understand nursing students' clinical experiences in newborn nurseries and neonatal intensive care units and to provide basic data for the establishment of strategies to promote effective clinical education. Methods: Interviews were held with 15 nursing students at J University who had clinical practice experience in the newborn nursery and neonatal intensive care unit. The collected data were analyzed using the phenomenological analysis method developed by Colaizzi (1978). Results: The nursing students' experiences were grouped into four categories: "expectations for and anxiety about clinical practice", "acquisition of a wide range of knowledge regarding neonatal nursing", "challenges faced in clinical practice", and "experiencing interpersonal changes". Conclusion: The current neonatal practice nursing education system provides students with positive learning experiences. However, the lack of practice opportunities, insufficient instruction, and the theory-practice gap were identified as major issues hindering students' learning needs. These study results are expected to provide basic data for curriculum development to improve undergraduate nursing education.

Purpose - This study aims to develop machine learning models to predict administrative issue designation in KOSDAQ Market using financial data. Design/methodology/approach - Employing four classification techniques including logistic regression, support vector machine, random forest, and gradient boosting to a matched sample of five hundred and thirty-six firms over an eight-year period, the authors develop prediction models and explore the practicality of the models. Findings - The resulting four binary selection models reveal overall satisfactory classification performance in terms of various measures including AUC (area under the receiver operating characteristic curve), accuracy, F1-score, and top quartile lift, while the ensemble models (random forest and gradienct boosting) outperform the others in terms of most measures. Research implications or Originality - Although the assessment of administrative issue potential of firms is critical information to investors and financial institutions, detailed empirical investigation has lagged behind. The current research fills this gap in the literature by proposing parsimonious prediction models based on a few financial variables and validating the applicability of the models.

In the quest for advancing diabetes diagnosis, this study introduces a novel two-step machine learning approach that synergizes the probabilistic predictions of Logistic Regression with the classification prowess of Random Forest. Diabetes, a pervasive chronic disease impacting millions globally, necessitates precise and early detection to mitigate long-term complications. Traditional diagnostic methods, while effective, often entail invasive testing and may not fully leverage the patterns hidden in patient data. Addressing this gap, our research harnesses the predictive capability of Logistic Regression to estimate the likelihood of diabetes presence, followed by employing Random Forest to classify individuals into diabetic, pre-diabetic or nondiabetic categories based on the computed probabilities. This methodology not only capitalizes on the strengths of both algorithms-Logistic Regression's proficiency in estimating nuanced probabilities and Random Forest's robustness in classification-but also introduces a refined mechanism to enhance diagnostic accuracy. Through the application of this model to a comprehensive diabetes dataset, we demonstrate a marked improvement in diagnostic precision, as evidenced by superior performance metrics when compared to other machine learning approaches. Our findings underscore the potential of integrating diverse machine learning models to improve clinical decision-making processes, offering a promising avenue for the early and accurate diagnosis of diabetes and potentially other complex diseases.

In this study, to figure out the demands for learning, a survey was conducted on learning organization agents participating in learning organization project supported by public fund, through measuring their awareness level of the role and tasks drawn from the precedent study. This questionnaire was developed with four roles and twenty competencies drawn from the precedent study. After conducting the survey on over 200 small and medium corporations participated in learning organization project, the data was analyzed about the role and competency from 123 answer sheets collected. The results were as following First, the awareness of role importance was higher(4.36) than present level(3.73), and was important in order of innovator, operator, spreader, promoter. Second, in competitive importance of learning organization agents, the role of spreader was high, that of promoter was low. Third, in awareness level of learning organization agents, the demand level was generally high(4.1), but acquired level was generally low, so there was a wide gap between the demand level and acquired level. Forth, From the analysis result of those data about work competency of learning organization agents, learning organization promoter and learning leader, KMS operator ability and outcome were come out to be necessary, and next administrative ability about organization changes were come out to be necessary.

The purpose of this study was to establish objectives for ninth grade studies of heredity and evolution in middle school in an attempt to foster students' consciousness of bioethics, and it's additionally intended to develop and apply lesson plans handling different points at issue and to determine the effects of the lesson plans on the bioethics of middle school students. The subjects in this study were 152 ninth graders in a middle school, whose science scores were similar. An experimental group and a control group were made up of 76 students respectively, and a pretest was conducted with test paper developed by this researcher to assess their awareness of bioethics. The experimental group took lessons by using the teaching plans prepared in this study, and the control group received typical education according to the curriculum. And then a posttest was implemented with test paper developed in this study to compare the two groups. In addition their science grades were compared as well. The findings of the study were as follows: First, seven learning objectives were selected from three units related to bioethics in the third-year 8th category of heredity and evolution of middle school. Second, in order to attain the selected learning objectives, four session lesson plans were prepared. Third, the experimental group that studied using by the lesson plans made better progress in bioethics awareness and the gap between the two was statistically significant(t=6.61, p<.001). The former were ahead of the latter in consciousness about species equity(t=7.71, p<.001), the dignity of life (t=3.78, p<.001), human rights(t=2.99, p<.01) and equity among generations(t=2.66, p<.01), but not in awareness of the diversity of species. Fourth, there was no significant gap in science scores between the students studied according to the curriculum and those who received instructions by using the lesson plans developed in the study.

Digital divide comes to appear as a new factor of causing social inequality with the entry of information society. Especially, the digital divide in student class makes a worry about education inequality as the education using ICT, e-learning, and u-learning are enlarged. So, the concern about the status of digital divide in school is increasing. In this study, we conducted a questionnaire survey of students and teachers in elementary and secondary schools located in Gyeongnam, and measured informatization level with the weighted average of three subindices : accessing index, capability index, and utilization index. According to the survey, the index on information processing capability showed the largest gap in both the student group and the teacher group. We also had the result of positive correlation between the capability index and the utilization index. These results show that the gap of information processing capability is an important factor for understanding the digital divide.

Level-Based Education is necessary for the multi-cultural learners because they tend to have the academic underachievement and learning deficiency that cause the huge educational gap. However, it is very hard to make the best of competence for the multi-cultural learners in the classroom. So, it is needed to suggest how we can use the educational contents that are appropriate for the Level-Based Learning and Individual Learning to make good use of teaching the learners from multi-cultural families. However, developing the new educational contents takes much time and cost, we have to improve existing contents for the student from multi-cultural families to use it. Hence, the purpose of this thesis is to develop the educational appropriateness evaluation scale to verify the educational contents that are for the multi-cultural students based on the educational content's evaluation tool, so by developing the scale, I intend to evaluate the 4~6 grades' Korean contents of the E-learning service and provide the ways of improvement.

The purpose of this study is to investigate elementary school students' understanding the concept and operations of decimal fraction. The survey research was performed for this study. This survey was done by selecting 156 students. Questionnaire were made in five areas with reference to the 2007 revised mathematics curriculum. Five areas were the concept of decimal fraction, the addition, the subtraction, the multiplication and the division of decimal fraction. The results of such analysis are as follow: The analyzed result of understanding about concepts and operation of decimal fraction showed a high rate of correct answer, more than 85%. Students thought that multiplication and division of decimal fraction is more difficult than addition, subtraction, concept of decimal fraction. As the learning about concepts and operation of decimal fraction progress, the learning gap is bigger. Effort to reduce the learning deficits are needed in the lower grades. Mathematics is the study of the hierarchical. Learning deficits in low-level interfere with the learning in next-level. Therefore systematic supplementary guidance for a natural number and decimal fraction in low-level is needed. And understanding concepts and principles of calculations should be taught first.
