Purpose: This descriptive research study explores the relationship between remote online classes, nursing students’ self-determined learning motivation and learning flow, to identify the mediating effect of academic emotion regulation. Methods: The study sample comprised 147 third- and fourth-year nursing students from two universities in Jeonbuk State, all of whom had clinical practice experience. Descriptive statistics, independent t-tests, and one-way analysis of variance were conducted using SPSS/WIN 23.0 for data analysis. Hayes’ PROCESS macro Version 3.5 was used to verify the significance of the indirect effects of the variables. Results: Self-determined learning motivation had a significant positive effect on the mediating variable, academic emotion regulation(β=.21, p=.001), and on learning flow. Additionally, academic emotion regulation significantly positively influenced learning flow. When considering the mediating effect of academic emotion regulation, the indirect effect size between self-determined learning motivation and learning flow was .07, with a bootstrapping confidence interval ranging from 0.02 to 0.13, excluding zero, which was statistically significant, indicating a mediating effect. Conclusion The findings confirm that academic emotion regulation is a crucial variable that can enhance students’ learning flow, thereby maximizing educational effectiveness during rapid changes in online education methods. Consequently, educational programs should be developed that consider the emotional aspects of learning to improve academic emotion regulation. Furthermore, universities should establish educational policies and measures that expand various digital education platforms to reflect and respond to the online education environment.

Purpose: This study aimed to grasp the correlation between communication ability, empathy, and interpersonal relations among nursing students, and to explore the mediating effect of empathy on the relation between communication and interpersonal relation in nursing students. Methods: Participants were 209 college students in the Department of Nursing at two universities. The data collection period was from October 1, 2019 to November 1, 2019. The questionnaire consisted of measuring tools for general characteristics, communication ability, interpersonal relation and empathy. SPSS/23.0 program was used. The analysis used descriptive statistics, Pearson's correlation coefficient, independent t-test, one-way ANOVA, multiple regression analysis, and Sobel's tests. Results: The communication ability was nursing major satisfaction (t=8.25, p<.001), and last year's average grade (t=7.29, p=.001). Interpersonal relationships showed significant differences in gender (t=2.51, p=.013) and nursing major satisfaction (t=10.99, p<.001). Communication ability and empathy (r=.37, p<.001), communication ability and interpersonal relation (r=.77, p<.001), empathy and interpersonal relation (r=.43, p<.001) showed a significant static correlation. In communication ability and interpersonal relation, empathy had a partial mediating effect (Z=2.97, p<.001), and explanatory power was 62%. Conclusion To improve the communication ability and interpersonal relation of nursing students, it is necessary to develop a personalized and empathy-enhanced education program for each grade.

This study investigated the effects of type D personality, depression and stress on quality of life in migraine patients and aimed to identify factors that affected their quality of life. Methods: In this descriptive study, the participants were 132 outpatients who were diagnosed with migraine at the Department of Neurology at J National University Hospital. The data were collected from June 20 to December 30, 2021, and analyzed using descriptive statistics, the independent t-test, the x2 test, one-way analysis of variance, the Scheffé test, Pearson correlation coefficients, and multiple regression. Results: The factors affecting quality of life in migraine patients were found to be type D personality (β=.58 p<.001) and depression (β=-.30 p<.001), and the explanatory power of the model was 53.0% (F=22.07, p<.001). Conclusion: It is necessary to develop a strategy for improving the quality of life for migraine patients that would consist of first identifying patients with type D personality and then offering them an intervention that addresses both physical symptoms and psychological health issues, such as depression.

Levosulpiride is one of the most frequently prescribed medicines in Korea. An adverse drug reaction (ADR) after taking levosulpiride was reported at a community pharmacy in Korea. A 31-year-old woman reported the symptoms of lactation and amenorrhea after taking levosulpiride; an evaluation of whether these symptoms were caused by the medication was therefore necessary. Several tools can be used to determine if the ADR resulted from the administered drug or other factors, including the World Health Organization-Uppsala Monitoring Centre (WHO-UMC) criteria, the Naranjo scale, and the Korean causality assessment algorithm (Ver. 2). The causality was evaluated as “possible” by the WHO-UMC and Naranjo scales, but as “probable” by the Korean causality assessment algorithm (Ver. 2). In conclusion, the information provided did not indicate definite causality and there were slight differences in the results obtained from each assessment method.

In order to solve the problems of traditional teaching model for medical statistics based on theoretical lecture, we developed new teaching model for medical statistics. The model was consisted of theoretical and practical lecture for 2nd grade of premedical students, Ewha Womans University. For theoretical lecture, we introduced basic concepts of medical statistics, data description and social survey method with questionnaire development. For practical lecture, we introduced the whole process from the selection for research topic to sampling, survey, data analysis, and report writing. Although students participated this class pointed out some trivial problems, they gave positive evaluation, particularly on practical lecture. We think this new model will be a good model and let medical students have ability to do medical research through basic knowledge and practical skill.

Conduction block or temporal dispersion on motor nerve conduction studies (NCSs) are known as key features of chronic inflammatory demyelinating polyneuropathy. Some types of CharcotMarieTooth disease (CMT) have been also reported to show conduction block or temporal dispersion on NCS. We experienced a case who presented with slowly progressive motor weakness, sensory loss, foot deformity, and segmental demyelination on NCS. We confirmed her and her mother harboring CMT1B with a novel p.Arg98Leu MPZ variant.

Objectives: Circadian misalignment may increase the risk of obesity and related obstructive sleep apnea (OSA). Considerable young adults have social jetlag (SJL), which is defined as the time discrepancy between workdays and free days. We aim to evaluate the relationship between SJL and sleep and respiratory disturbance in patients with untreated OSA patients. Methods: A total of 180 OSA patients under the age of 50 [mean 38.3±8.0 y, 93.3% male, mean apnea-hypopnea index (AHI) 38.2±27.4 /h] were recruited from the university affiliated sleep clinic and fulfilled sleep-related questionnaires including Munich Chronotype Questionnaire (MCTQ). SJL was defined as the difference in sleep midpoints between work and free days. Patients were divided into three groups with SJL less than 1 hour, 1–2 hours, and 2 hours or more and the clinical and sleep data of each group were compared. Results: 51.6% (n=93) suffered from significant SJL (≥1 h). Patients with ≥2h of SJL (16.6%, n=30) had the largest neck circumference (NC). AHI and sleep parameters were not significantly different among groups except lowest oxygen saturation (LoS) was the lowest in the group of ≥2 h. SJL was positively correlated with body mass index and NC and negatively correlated with LoS after adjusting for age and sex. Conclusions About a half of young adults with OSA have significant SJL more than 1 h. This study suggests that SJL is associated with being overweight, while it seems not increase the severity of OSA nor deteriorate sleep quality in young adults.

Pseudohypoparathyroidism (PHP) is a rare disorder caused by genetic and epigenetic aberrations in the GNAS complex locus resulting in impaired expression of stimulatory G protein (Gsα). PHP type Ib (PHP-Ib) is characterized by hypocalcemia and hyperphosphatemia due to renal resistance to the parathyroid hormone, and is distinguished from PHP-Ia by the absence of osteodystrophic features. An 11-yr-old boy presented with poor oral intake and cramping lower limb pain after physical activity. Laboratory studies revealed hypocalcemia, hyperphosphatemia, and increased parathyroid hormone levels. The GNAS complex locus was evaluated using the methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) assay. Gain of methylation in the NESP55 domain and loss of methylation in the antisense (AS) transcript, XL, and A/B domains in the maternal allele were observed. Consequently, we present a case of PHP-Ib diagnosed using MS-MLPA.

Background: Plasma cell myeloma (PCM) is a genetically heterogeneous disease. The genetic spectrum of PCM has been expanded to mutations such as KRAS, NRAS, and BRAF genes in the RAS-RAF-MAPK pathway. In this study, we have evaluated the frequency of these mutations and their significance, including baseline characteristics and clinical outcomes. Methods: We explored 50 patients who were newly diagnosed with PCM between 2009 and 2012 at a single Korean institute. Clinical and laboratory parameters were gathered through careful review of medical records. Mutation analysis was carried out using DNA from the bone marrow at the time of diagnosis. Pyrosequencing was performed to detect KRAS G12V,KRASG13D, and NRAS G61R. BRAF V600E was analyzed by allele-specific real-time PCR. Comparison of clinical and laboratory parameters was carried out according to those mutations. Results: We identified 14 patients (28%) with activating mutations in the RAS-RAF-MAPK pathway (RAS/RAF mutations):KRAS (N=3), KRAS (N=4),BRAF (N=7), and both KRAS and BRAF (N=1). RAS/RAF mutations were more frequently observed in patients with complex karyotypes and showed poorer progression free survival (PFS). Specifically, the BRAF V600E mutation had a significantly negative impact on median PFS. Conclusion We first showed the frequency of RAS/RAF mutations in Korean patients with PCM.Screening of these mutations could be considered as a routine clinical test at the time of diagnosis and follow-up due to their influence on clinical outcome, as well as its potential as a therapeutic target.
