This paper discusses the development of an educational web-based power flow program for undergraduate students. The interaction between lectures and users can be much enhanced via the web-based programs which result in the student's learning effectiveness on the power flow problem. However the difficulties for developing web-based application programs are that there can be the numerous unspecified users to access the application programs. To overcome the aforementioned multi-users problem and to develope the educational web-based power flow program, we have revised the system architecture, the modeling of application programs, and database which efficiently and effectively manages the complex data sets related to the power flow analysis program. The developed application program is composed of the physical three tiers where the middle tier is logically divided into two kinds of application programs. The divided application programs are interconnected by using the Web-service based on XML (Extended Markup Technology) and HTTP (Hyper Text Transfer Protocol) which make it possible the distributed computing technology Also, this paper describes the method of database modeling to handle effectively when the numerous users change the parameters of the power system to compare the results of the base case.

This paper compares efficiency results and performance targets for academic departments in a local private college using DEA (Data Envelopment Analysis). Because of an aging society, a smaller school-age population entering colleges, and enhanced accreditation standards by the government, colleges and universities are not recruiting and retaining sufficient students and therefore are struggling for survival. In contrast to popular four-year undergraduate universities concentrated in Seoul and its satellite cities, retaining students is critical for the survival of local private colleges in poor or remote regions. Therefore, it is very important to identify the factors involved in the retention of students in the various departments of a college. However, given the different characteristics of the departments, it is difficult to identify one unique or robust set of standards to evaluate their performance. The purpose of this paper is to maximize student retention capabilities by ensuring that additional resources are assigned to efficient DMUs, while, inefficient DMUs are given benchmarked targets. Based on previous studies and college accreditation standards, this paper presents indices to be used in evaluating the efficiency of academic departments in a college. In evaluating relative efficiency, this paper uses the output-oriented BCC model. To define target levels to be achieved for efficient DMU, a multi-stage DEA procedure is used.

Purpose: The purpose of this study was to examine the effects of the teaching effectiveness and clinical learning environment on the clinical practice competency in nursing students. Method: Undergraduate nursing students (268) enrolled in one of 4 universities in 2 cities completed a survey questionnaire. Collected data were analyzed using descriptive statistics, Pearson's correlation coefficient and multiple regression with the SPSS/Win 11.0 program. Results: The mean score for teaching effectiveness was 3.09 (${\pm}.53$) on a 5-point scale, for clinical learning environment, 3.09 (${\pm}.50$) on a 5-point scale, and for clinical practice competency, 3.94 (${\pm}.52$) on a 6-point scale. Significant positive correlations were found between teaching effectiveness and clinical learning environment, and clinical practice competency. The regression model explained 8.8% of clinical practice competency. Teaching effectiveness and clinical learning environment were significant predictors of clinical practice competency. Conclusion: The findings of the study suggest that teaching effectiveness and clinical learning environment be considered when developing strategies to increase clinical practice competency in nursing students.

Purpose: The purpose of this study was to analyze the experiences and perceptions of nursing students related to their cadaver practice through an integrative review. Methods: An integrative review was conducted using Whittemore and Knafl's framework published in 2005. The key words, "nursing students & cadaver" and "nursing students & anatomy" were used to search peer-reviewed publications in six databases. Among 373 searched articles, 15 articles were selected after excluding articles that did not meet the inclusion criteria. The literature quality was moderate (levels C and B). Results: The results from the 15 selected studies were integrated and classified into seven themes: "anxiety and discomfort," "gratitude and respect for donors," "dignity of the human body and life," "acceptance of death," "getting closer to the nursing profession," "enhanced understanding and memory of the human body" and "enhancement of learning motivation." Conclusion: In conclusion, cadaver practice provided an opportunity to form values about the dignity of life and death, helped nursing students understand the human body, and motivated them to approach the profession of nursing. It is suggested to develop integrated cadaver practice programs that incorporate bioethics, spiritual nursing, and the vocation of the nursing profession.

Background: The purpose of this study was to examine undergraduate medical students' perceptions and intentions regarding patient safety during clinical clerkships. Methods: Cross-sectional and self-administered questionnaire survey was conducted on 34 students from one medical school using a modified version of the Medical Student Safety Attitudes and Professionalism Survey (MSSAPS). We assessed $4^{rd}-year$ medical students' perceptions of the cultures ('safety', 'teamwork', and 'error disclosure'), 'behavioural intentions' concerning patient safety issues and 'overall patient safety'. The overall response rate was 66.4%. Results: Among safety domains, "teamwork culture" was rated highest. "Error disclosure culture" received the lowest ratings. Regarding the error disclosure domain, only 10% of respondents reported that they have received education or training on how to disclose medical error to patients. Independent of survey domains, when students were asked "Overall, do you think your hospital is safe based on your clinical rotation?", 61.8% reported that the hospital was safe. Conclusions: Assessing students' perceptions of safety culture can provide clerkship directors and educators with information that enhances the educational environment and promotes patient safety. Discussions of medical errors, patient safety, and how best to incorporate an analysis of these issues into the existing curriculum are needed.

Despite the importance of learning to do mathematical proofs, researchers have reported that not only secondary school students but also undergraduate students have difficulties in learning proofs. In this study, we introduced a new toll for learning proofs and explored the reliability and the validity of peer assessment on proofs. In the course of a university in Seoul, students were given weekly proof assignments prior to class. After solving the proofs, each student had to assess other students' proofs. The inter-rater reliabilities of weekly peer assessment was higher than .9 over 90 percent of the observed cases. To examine the validity of peer assessment, we check whether students' assessments were similar to expert assessment. Analysis showed that the equivalence has been quite high throughout the semester and the validity was low in the middle of the semester but rose by the end of the semester. Based on these results, we believe instructors can consider the application of peer assessment on proving tasks as a tool to help students learn.

Few studies have utilized observational methods in the field of couple research even though using self-report questionnaires is prone to the subjective biases of the reporter. This study validates the Marital Interaction Coding System-Global (MICS-G), a global version of the well-established microanalytic observational coding system, Marital Interaction Coding System (MICS). Participants in the study consisted of 30 married couples with varied levels of marital adjustment who visited one of the Healthy Family and Multicultural Family Support Centers in Seoul, either for couple therapy or the "Marriage Checkup"program. Ten-minute problem-solving discussions were rated by two undergraduate student raters who were trained for 10 hours. Interobserver agreement based on percentage agreement and intraclass correlation coefficients showed a high level of agreement between raters in establishing interrater reliability. Convergent validity was established by: correlations among marital adjustment, psychological aggression, mental health, and MICS-G categories of conflicts, validation, invalidation, facilitation, and withdrawal. MICS-G categories also were successful in discriminating between distressed and nondistressed couples, which provides evidence of discriminant validity for MICS-G. This study showed that MICS-G is a promising method for researchers to observe couple interactions in a more cost-effective way. Methodological issues and practical applications are also discussed.

The purpose of this study is to compare learners' perceptions regarding the processes and the educational effects of fostering learner-generated questions in engineering education according to the questioning attitude of engineering learners. For this, after developing and implementing the appropriate strategies for fostering learner-generated questions in an engineering statistics course, this study analyzed 56 learners' survey responses and used ANOVA to investigate the group differences. The results showed that the educational effects and implications of fostering learner-generated questions were different according to the learners' questioning attitude. The study also confirmed that learners' questioning attitude should be considered as one of the important learner's characteristics in developing and implementing the strategies of fostering learner-generated questions in engineering education. Especially, fostering learner-generated questions produced positive effects on the passive questioning learners but not particularly on the learners who were asking no questions at all in other courses. Learners who asked no questions still have difficulty in generating deep meaningful questions and presenting them and thus require more instructors' strategies and active support for them.

On July 6, 2021, the Ministry of Education revised and announced the operating regulations of the undergraduate co-op with the aim of protecting students rights and student-centered operation based on mutual benefits for students and institutions. Therefore, the purpose of this study is to analyze universities' perceptions against the amendment of regulation of the Ministry of Education's into universities/college, regions. According to a survey of 75 KACE, we found that colleges are more difficult than universities in terms of administrative work, company participation, reduced opportunities for co-op, and managing participating companies. Next, most of the regional differences in difficulties were not significant, and only the decline in company participation rate was more difficult in Daegyoung/Gangwon/Chungcheong/Jeju than in the metropolitan area. Finally, policy directions such as the differential application of practical support expenses according to the size of the company, tax benefits for institutions, and clarification of the concept of job training were presented.

Pusan National University School of Medicine (PNUSOM) began analyzing the cohort of pre-medical students admitted in 2015 and has been conducting purposeful analyses for the past 3 years. The aim of this paper is to introduce the process of cohort establishment, cohort composition, and the utilization of cohort analysis results. PNUSOM did not initially form a cohort with a purpose or through a systematic process, but was able to collect longitudinal data on students through the establishment of a Medical Education Information System and an organization that supports medical education. Cohort construction at our university is different in terms of a clear orientation toward research questions, flexibility in cohort composition, and subsequent guideline supplementation. We investigated the relevance of admission factors, performance improvements, satisfaction with the educational environment, and promotion and failure rate in undergraduate students, as well as performance levels and career paths in graduates. The results were presented to the Admissions Committee, Curriculum Committee, Learning Outcomes Committee, and Student Guidance Committee to be used as a basis for innovations and improvements in education. Since cohort studies require long-term efforts, it is necessary to ensure the efficiency of data collection for graduate cohorts, as well as the validity and ethics of the study.
