Purpose:
The purpose of this study is to identify the educational needs of a severe trauma treatment simulation program based on mixed reality which combines element of both virtual reality and augmented reality.
Methods:
Focus group interviews were conducted with ten military hospital nurses on February 4 and 5, 2021. The collected data were analyzed using a qualitative content analysis. As a framework for data analysis, the educational needs were clustered into the following four categories: teaching contents, teaching methods, teaching evaluation, and teaching environment.
Results:
The educational needs for each category that emerged were as follows: three subcategories including “realistic education reflecting actual clinical practice” and “motivating education” for teaching contents; five subcategories including “team-based education,” “repeated education that acts as embodied learning,” and “stepwise education” for teaching methods; six subcategories including “debriefing through video conferences,” “team evaluation and evaluator in charge of the team,” “combination of knowledge and practice evaluation” for teaching evaluation; six subcategories including “securing safety,” “similar settings to real clinical environments,” “securing of convenience and accessibility for learners,” and “operating as continuing education” for teaching environment.
Conclusion
The findings of this study can provide a guide for the development and operation of a severe trauma treatment simulation program based on mixed reality. Moreover, it suggests that research to identify the educational needs of various learners should be conducted.

BACKGROUND: The visceral fat obesity is known to be associated with coronary artery disease. We investigated the relation between visceral fat obesity and the severity of coronary artery disease by angiography. METHODS: The coronary artery disease (CAD) group included 54 angina patients (43 men and 11 women) with angiographically demonstrated coronary artery disease. The control group included angiographically normal 28 controls (15 men and 13 women). The subjects with hypertension, non-insulin dependent diabetes mellitus (NIDDM) and taking any medication known to affect the insulin sensitivity were excluded. We measured the visceral fat area, abdominal subcutaneous fat area, thigh muscle area and the thigh fat area with computed tomography (CT) in both groups. We measured the plasma lipid profile, fasting plasma insulin and glucose level in both groups. RESULTS: There were no differences in the age, sex ratio and body mass index (BMI) between both groups. Total cholesterol and triglyceride increased in CAD group significantly (p<0.05, p<0.001). The HDL cholesterol decreased in CAD group. But there was no statistical significance (p=0.056). The fasting insulin increased in CAD group significantly (p<0.001). There were significant differences between CAD group and the control group in the visceral fat area (117.8+/-34.4 cm2vs. 85.5+/-17.6 cm2, p<0.001), thigh fat area (50.0+/-22.3 cm2vs. 65.8+/-12.9 cm2, p<0.001), visceral fat to abdominal subcutaneous fat area ratio (VS ratio:0.81+/-0.31 vs. 0.51+/-0.15, p<0.001) and the visceral fat to thigh fat area ratio (VSFTF ratio:2.72+/-1.24 vs. 1.34+/-0.35, p<0.001). In the male subgroup (CAD:43, control:15), triglyceride and fasting insulin increased in CAD group significantly (p<0.001). The visceral fat area, VS ratio, and VSFTF ratio increased in CAD group significantly (P<0.001) The thigh fat area decreased in CAD group significantly (P<0.001). In the female subgroup (CAD:11, control:13), fasting insulin and visceral fat area increased in CAD group significantly (p<0.001, p<0.05). Multiple logistic regression analysis revealed that VSFTF ratio, fasting insulin and the HDL cholesterol were independent associated factors of coronary artery disease. In comparison with normal control, one-vessel disease and multi-vessel disease (two vessel and three vessel), there were significant differences between groups in fasting insulin, triglyceride, visceral fat area, thigh fat area, VS ratio, VSFTF ratio. In Turkey's HSD Post Hoc test, however, there were no significant differences between one-vessel disease and multi-vessel disease. CONCLUSION: We observed significant increases in the visceral fat area, VS ratio and VSFTF ratio and decrease in thigh fat area in angiographically demonstrated CAD group compared with age, BMI matched angiographically normal control. But we did not observed any relation between the visceral fat area and the severity of coronary disease by angiography.

Policosanol extracted from sugarcane wax is a generic term used for total fatty alcohols obtained from esterification of fatty acids. It has been approved as a health functional food by the Ministry of Food and Drug Safety of Korea in 2006. Policosanol is well-known to aid in lowering blood cholesterol level. Recently, several studies have reported the physiological activities of policosanol, such as anti-inflammatory effects, antioxidant effects, and lowering of the incidence of ageing-related diseases, for example, hypertension, stroke, among others. This review describes the physiological activities of policosanol and its applications in the field of health functional foods.

PURPOSE: The smoking rates among teenagers in Korea grow gradually since 1980s despite of the numerous programs for youth smoking prevention and cessation have been developed and implemented. The purpose of this study was to explore and describe the processes of habituating to smoking among teenagers using the grounded theory methodology. METHOD: Qualitative data was collected via six focus group interviews. A total of 38 people, twelve teachers and 24 middle school students participated in this study. All focus group interviews were tape-recorded, transcribed, and analyzed according to the grounded theory methodology. RESULTS: The overriding theme of the elicited grounded theory was "stepping into a quagmire by a merest chance". The student participants began smoking by a simple chance. The contingent factors to starting smoking were "discord within the family", "family member's smoking", "schoolwork stresses", or "a rebellious spirit". The conditions of smoking included accessibility, going around in group, and the lack of discipline. "Stigmatizing", "involved in mob violence", and "making a poor academic record" coexisted as the covariance of the smoking habituation. CONCLUSION: The findings of this study illustrated the comprehensive and insightful picture of the phenomena under investigation. Nursing implications and further directions for research were discussed.

BACKGROUND: Psychogenic non epileptic seizures (PNES) are characterized by repeated seizures that are typically caused by stress and psychologic problems such as anxiety and depression. This contrasts with epileptic seizures (ES), which are transient and caused by irregular excitement of nerve cells. PNES can be found in patients with ES, but due to their differing etiologies, it is important to determine the psychologic characteristics that differentiate PNES from ES. METHODS: This study identified psychopathologic and personality traits in 137 patients with PNES (n=7, 49.3% female) or ES (n=0, 35.7% female) using MMPI. The diagnosis was based on a medical history of seizures and the clinical examination in patients who visited the epilepsy clinic. Statistical analyses for comparing MMPI differences between the two groups were conducted using the t-test, chi-square test, and analysis of covariance. RESULTS: We analyzed the frequency of individuals who exhibited a T score of ≥5 on the MMPI, and the results indicated that there were significantly more patients in the PNES group than in the ES group who had elevated scores on the hypochondriasis (Hs) scale and hysteria (Hy) scale. The mean scores of Hs, Hy, paranoia scale and schizophrenia scale were significantly higher in the PNES group than in the ES group. CONCLUSIONS: These results suggest that patients with PNES have greater psychologic problems than ES patients. Differences in MMPI profile patterns between patients with PNES and ES may be helpful in tailoring appropriate therapeutic interventions for the two groups.

PURPOSE: The purpose of this study was to investigate the occurrence of first onset of constipation during the rehabilitation stage and risk factors for constipation in patients with cerebral vascular disease (CVD). METHODS: Participants for this retrospective study were 214 CVD patients admitted to rehabilitation units. First onset of constipation and factors influencing constipation such as dependency level were recorded for 14 days during the rehabilitation stage. Survival analysis with Cox proportional hazard model and descriptive statistics were conducted. RESULTS: Age, patients'severity, types of diet, and dependency level were different between constipation and non-constipation groups. In survival analysis, 99% of participants developed constipation within 14 days after admission to rehabilitation units. Median constipation occurrence time was 7.4 days. Patients who were immobile and had tube feedings were more likely to develop constipation 4.07 times (95% CI: 1.018~16.301, p=.047) and 2.09 times (95% CI: 1.001~4.377, p=.050) respectively compared to patients who were independent and had a regular diet, respectively. CONCLUSION: Most CVD patients experienced constipation within 2 weeks after entering the rehabilitation stage. Constipation was linked to types of diet and dependency level. These factors associated with constipation should be considered when caring for patients in rehabilitation.

In recent years, as the aging population grows, aging-induced cognitive impairments including dementia and Alzheimer's disease (AD) have become the biggest challenges for global public health and social care. Therefore, the development of potential therapeutic drugs for aging-associated cognitive impairment is essential. Metabolic dysregulation has been considered to be a key factor that affects aging and dementia. Adenosine monophosphate (AMP)-activated protein kinase (AMPK) is a primary sensor of cellular energy states and regulates cellular energy metabolism. Metformin (1,1-dimethylbiguanide hydrochloride) is a well-known AMPK activator and has been widely prescribed for type 2 diabetes mellitus (T2DM). Since the incidence of T2DM and dementia increases with aging, metformin has been considered to be one of the most promising drugs to target dementia and its related disorders. To that end, here, we tested the efficacy of metformin and HL271, a novel metformin derivative, in aging-induced cognitive decline. Water (control), metformin (100 mg/kg) or HL271 (50 mg/kg) were orally administered to aged mice for two months; then, the mice were subjected to behavioral tests to measure their cognitive function, particularly their contextual, spatial and working memory. AMPK phosphorylation was also measured in the drug-treated mouse brains. Our results show that oral treatment with HL271 (50 mg/kg) but not metformin (100 mg/kg) improved cognitive decline in aged mice. AMPK activation was correlated with behavior recovery after aging-induced cognitive decline. Taken together, these results suggest that the newly synthesized AMPK activator, HL271, could be a potential therapeutic agent to treat age-related cognitive decline.

The TMEM43 has been studied in human diseases such as arrhythmogenic right ventricular cardiomyopathy type 5 (ARVC5) and auditory neuropathy spectrum disorder (ANSD). In the heart, the p.(Ser358Leu) mutation has been shown to alter intercalated disc protein function and disturb beating rhythms. In the cochlea, the p.(Arg372Ter) mutation has been shown to disrupt connexin-linked function in glia-like supporting cells (GLSs), which maintain inner ear homeostasis for hearing. The TMEM43-p.(Arg372Ter) mutant knock-in mice displayed a significantly reduced passive conductance current in the cochlear GLSs, raising a possibility that TMEM43 is essential for mediating the passive conductance current in GLSs. In the brain, the two-pore-domain potassium (K2P) channels are generally known as the “leak channels” to mediate background conductance current, raising another possibility that K2P channels might contribute to the passive conductance current in GLSs. However, the possible association between TMEM43 and K2P channels has not been investigated yet. In this study, we examined whether TMEM43 physically interacts with one of the K2P channels in the cochlea, KCNK3 (TASK-1). Utilizing co-immunoprecipitation (IP) assay and Duolink proximity ligation assay (PLA), we revealed that TMEM43 and TASK-1 proteins could directly interact. Genetic modifications further delineated that the intracellular loop domain of TMEM43 is responsible for TASK-1 binding. In the end, gene-silencing of Task-1 resulted in significantly reduced passive conductance current in GLSs. Together, our findings demonstrate that TMEM43 and TASK-1 form a protein-protein interaction in the cochlea and provide the possibility that TASK-1 is a potential contributor to the passive conductance current in GLSs.

Journal of the Korean Society of Maternal and Child Health 2023;27(2):71-79
Purpose:
This quasi-experimental single group study aimed to confirm the effects of discharge education using a systematic discharge education program on anxiety and parenting confidence in mothers of premature babies.
Methods:
This study conducted discharge education for 3 to 5 days prior to the discharge of 29 mothers of premature babies born in the neonatal intensive care unit. Data were collected between April 1, 2021, to June 30, 2021, and were examined. The hypotheses were analyzed using the Wilcoxon signed-rank test.
Results:
Discharge education using a systematic discharge education program was effective in increasing the parenting confidence of mothers with premature babies (z=-3.839, p<0.001). However, it was not effective in reducing anxiety (z=-1.712, p=0.087).
Conclusion
The effects of the systematic discharge education program development and discharge education systematized discharge nursing education, reduced mothers’ anxiety in raising premature babies at home after discharge, and contributed to improving parenting confidence.

Journal of Korean Academy of Nursing 2020;50(4):501-512
Purpose:
The purpose of this study was to analyze articles published in the Journal of the Korean Academy of Nursing (JKAN) between 2010 and 2019, along with those published in three international nursing journals, to improve JKAN’s international reputation.
Methods:
The overall characteristics of JKAN’s published papers and keywords, study participants, types of nursing interventions and dependent variables, citations, and cited journals were analyzed. Additionally, the keywords and study designs, publication-related characteristics, journal impact factors (JIF), and Eigenfactor scores of International Journal of Nursing Studies (IJNS), International Nursing Review (INR), Nursing & Health Sciences (NHS), and JKAN were analyzed and compared.
Results:
Among the four journals, JKAN’s score was the lowest in both the journal impact factor and Eigenfactor score. In particular, while the JIF of INR and NHS has been continuously increasing; JKAN’s JIF has remained static for almost 10 years. The journals which had cited JKAN and those which JKAN had cited were mainly published in Korean.
Conclusion
JKAN still has a low IF and a low ranking among Social Citation Index (E) journals during the past 10 years, as compared to that of four international journals. To enhance JKAN’s status as an international journal, it is necessary to consider publishing it in English and to continuously improve the conditions of other publications.
