PURPOSE: The purpose of this study was to examine the effects of a virtual reality simulation and a blended simulation on nursing care for children with asthma through an evaluation of critical thinking, problem-solving processes, and clinical performance in both education groups before and after the educational intervention.METHODS: The participants were 48 nursing students. The experimental group (n=22) received a blended simulation, combining a virtual reality simulation and a high-fidelity simulation, while the control group (n=26) received only a virtual reality simulation. Data were collected from February 25 to 28, 2019 and analyzed using SPSS version 25 for Windows.RESULTS: The pretest and posttest results of each group showed statistically significant improvements in critical thinking, problem-solving processes, and clinical performance. In a comparison of the results of the two education groups, the only statistically significant difference was found for critical thinking.CONCLUSION: Simulation-based education in child nursing has continued to involve high-fidelity simulations that are currently run in many programs. However, incorporating a new type of blended simulation, combining a virtual reality simulation and a high-fidelity simulation, into the nursing curriculum may contribute to the further development of nursing education.

PURPOSE: The purpose of this study was to explore nursing students' experiences of debriefing after simulation-based learning and to obtain fundamental data to support the development of effective teaching strategies. METHODS: Sixty-seven nursing students participated in this study from April to May, 2017. This was a descriptive study analyzing the content of students' descriptions of structured questions in 3 stages (description, analysis, and application) based on recorded videos. RESULTS: The description stage was classified into 3 categories for problem recognition, 4 categories for the nursing plan, and 6 categories for the nursing intervention. The analysis stage was classified into 6 categories for satisfactory practice, 3 categories for experience and 4 categories for what they learned through practice. The application stage was classified into 5 categories, that were to be mastered, and 6 categories, that were important to recognize. CONCLUSION: This study succeeded in charaterizing learners' experiences of debriefing. During the debriefing, students watched recorded videos, and we found that self-evaluation through structured questionnaires could be a very effective way to strengthen students' core competencies. Our content analysis of the debriefing is expected to contribute to the development of effective strategies in simulation-based education for students and nurses.

BACKGROUND AND OBJECTIVES: Dizziness has been known as a prognostic factor in sudden sensorineural hearing loss (SSHL), but it is difficult to describe and quantify its subjective symptoms. Also, dizziness itself cannot imply vestibular dysfunction in SSHL. Comprehensive evaluation of vestibular function may help us understand the extent of lesions in sudden deafness. The purpose of this study is to determine whether an impaired caloric response is associated with disease severity and hearing outcome. SUBJECTS AND METHOD: A retrospective chart review was conducted of 488 patients diagnosed as unilateral SSHL. The patients were divided into two, an abnormal caloric group (canal paresis >20%) and normal caloric group (canal paresis ≤20%). Initial demographic and audiologic findings and final hearing outcomes were compared between the two groups. RESULTS: The initial pure tone averages of SSHL patients of abnormal caloric group and normal caloric group were 75.4±28.4 dB HL and 68.2±25.4 dB HL (p=0.004), respectively. Patients of abnormal caloric test group showed worse hearing outcome across all frequencies compared to those of the normal caloric group. Also, a significant correlation was noted between the magnitude of hearing recovery and canal paresis (r=-0.223, p < 0.001). CONCLUSION: SSHL patients of abnormal caloric test showed worse initial hearing level and poorer hearing outcome. Evaluation of vestibular function in SSHL patients is important because subjective symptoms alone cannot account for vestibular hypofunction patients, and the caloric test can help in the counseling of patients and prediction of hearing outcome in SSHL patients.

PURPOSE: This study examined and compared the associations of the iron status and food intake with the blood lead, mercury, and cadmium concentrations among Korean adolescent girls, premenopausal women, and postmenopausal women. METHODS: The data from the 2010~2011 Korea National Health and Nutrition Examination Survey (KNHANES) was used. The subjects were classified into three groups: adolescent girls (n = 268), premenopausal women (n = 1,157), and postmenopausal women (n = 446). The iron status was assessed by hemoglobin, hematocrit, serum ferritin, and iron concentrations, as well as the total iron binding capacity (TIBC). The food intake was estimated by a food frequency questionnaire. RESULTS: The blood heavy metal concentrations and poisoning rate in postmenopausal women were higher than in the other groups. The iron status in the adolescent girls and postmenopausal women was higher than that in the premenopausal women. In the adolescent girls, the iron status was inversely associated with the blood cadmium concentration. The dairy food intake was inversely related to the blood lead and cadmium concentrations. In premenopausal women, the iron status was inversely associated with the cadmium concentrations. The fish and shellfish food intakes were positively associated with the mercury concentrations. In postmenopausal women, the iron status was positively associated with the mercury and cadmium concentrations. Fast foods and fried foods were inversely associated with the lead concentration. CONCLUSION: The premenopausal women showed a lower iron status than the adolescent girls and postmenopausal women. The associations of the iron status with the blood heavy metal concentrations were different among the adolescent girls, premenopausal women, and postmenopausal women. In addition, the relationships of the food intakes with the blood heavy metal concentrations differed among adolescent girls, premenopausal women, and postmenopausal women. Further studies will be needed to confirm these findings.

This study aimed to provide supporting data for the management of dietary habits in depression by comparing health and nutrition in adult Korean women according to depression status. A total of 2,236 women aged between 19 and 64 years who participated in the 2013 Korea National Health and Nutrition Examination Survey were divided into a depression group (n = 315) and a non-depression group (n = 1,921). Among 19-29-year-old women, the depression group showed higher proportions of individuals with impairment of everyday activities, menopause, and suicidal thoughts than the non-depression group. The depression group showed lower intake of cereal, chocolate, meat, and carbonated drinks, as well as a lower index of nutritional quality (INQ) for protein, iron, and niacin. Among 30-49-year-old women, the depression group showed higher proportions of individuals with impairment of everyday activities, chronic disease, stress, and suicidal thoughts. The depression group showed lower intake of rice with mixed grains and higher intake of instant and cup noodles than the non-depression group. Among 50-64-year-old women, the depression group showed higher proportions of individuals with impairment of everyday activities, menopause, stress, and suicidal thoughts. The depression group showed lower intake of vegetables, mushrooms, and seaweed, lower nutritional intake of fat, saturated fat, and n-3 fatty acids, as well as a lower INQ for niacin and a lower Recommended Food Score. For all age groups, individuals with depression showed poorer health and nutritional intake than healthy individuals, demonstrating a correlation of depression with health and nutritional intake.

PURPOSE: The current study was conducted in order to identify health and nutritional status of Korean underweight women in their twenties by comparing with normal, overweight, and obese women. METHODS: Data from the 2010~2012 Korea National Health and Nutrition Examination Survey were used in this study. Subjects were 897 women aged 20~29 years. Subjects were classified according to underweight, normal weight, overweight, and obese groups based on body mass index. Health status was assessed using data from the health questionnaire and examination. Nutritional status was assessed using data from 24-hour dietary recall and a food frequency questionnaire. RESULTS: The underweight group had higher education and exercised less than the obese group. Means of blood chemistry and blood pressure of the underweight group did not differ from those of the normal weight group. Means of fasting glucose, insulin, lipid profiles, blood cell counts, and blood pressure in the underweight group were different from those of the overweight or obese group. Proportions of delivery, breast feeding, and irregular menstruation in the underweight group were lower compared with the other groups. Except retinol intake, means of nutrient intake did not differ among four groups. There were significant differences among four groups in the intakes of cereals and eggs and frequency of consumption of dairy products. CONCLUSION: The current findings showed that health and nutritional status of underweight women in their twenties did not differ from those of normal weight women. In particular, health status of underweight women in their twenties was better than that of obese women of the same ages. Further study on health and nutritional status of extremely underweight women is necessary.

PURPOSE: The objective of this study was to examine the effect of the body shape discordance, the difference between true body type based on body mass index (BMI) and self-recognized body image, on nutrient intake, weight control attempt, and mental health in Korean adults. METHODS: Subjects were persons aged 19~64 years (4,382 men and 6,226 women) who participated in the 2010~2012 Korea National Health and Nutrition Examination Survey. Subjects were categorized as RL (Group recognized as lighter than BMI criteria), RA (Group with agreement between BMI criteria and self-recognized body image), and RH (Group recognized as heavier than BMI criteria) according to the difference between actual body type based on BMI and self-recognized body image. RESULTS: Means of BMI in RH groups were lower than or equal to that of RA groups in all groups. No significant differences in total energy intake were observed among the three groups in men, but total energy intake was higher in the RL group than in the RH group in 30~49 year old women. Proportion of carbohydrate was the highest in the RL group among 30~49 year old women. RH groups paid more attention to weight control and had less weight gain than other groups. Higher proportions of depressive symptoms were reported in the RH group in 19~29 year old men, while a higher proportion of depressive symptoms were reported in the RL group in 50~64 year old men. CONCLUSION: The current findings suggest an association of perceiving body shape with energy intake, weight control attempt, or depressed mood in some age groups. Body image perception can influence eating, weight control attempt, and depressed mood, therefore proper body image perception should be established in Korean adults.

BACKGROUND AND OBJECTIVES: Bone conduction (BC) auditory brainstem response (ABR) is an important factor in determining the type of hearing loss especially in infants and other difficult-to-test populations. However, multiple constraints including technical difficulties make evaluating BC ABR less feasible in the clinic, and there is also lack of information that guides clinicians how to evaluate it. The purpose of this study is to compare the latency of wave V in BC and air conduction (AC) ABR in normal hearing infants and gather reference values for wave V latency of BC ABR. SUBJECTS AND METHOD: A total of 210 ears of normal hearing, of those not belong to the hearing loss risk group, were included. All the infants underwent ABR evoked by clicks via AC (3A insert phone) and BC (Radioear B-71, vibrator positioned on the mastoid) under sedation. The latency of wave V at 30 dB nHL by BC and AC was compared and analyzed according to age. RESULTS: The results revealed that in every age group in the study, wave V latency at 30 dB nHL of BC ABR was shorter than that of AC ABR. There was a significant decrease in BC and AC latencies with age, but among each consecutive age group, significant latency change was not identified after 6 months old. CONCLUSION: The latency of BC ABR in young children was shorter than that of AC ABR, and it decreased significantly as age increased. However, the reference data should be considered by taking each laboratory's test parameter into consideration.

PURPOSE: This descriptive study was performed to explore trends in child health nursing research by analyzing the themes, contents and structure of articles published in 2014 in Child Health Nursing Research, the official journal of the Korean Academy of Child Health Nursing. METHODS: Thirty-eight articles were reviewed using keywords, author (s), subjects, ethical considerations, designs, statistics involved, funding resources, and others. RESULTS: Ten domains from 160 keywords were identified as follows, child related, psycho-social variable related, parents and family related, nursing and health related, and others. A mean of 2.9 authors per article was identified and 71% of the authors were academic- affiliated. Twenty-eight articles were human-participant related while 21 articles addressed both Institutional Review Board and written consent. Non-experimental design was the most commonly used method followed by experimental design, and qualitative design. The duration for acceptance was a mean of 89.1 days from submission with most articles requiring a second round of article review. Half of the articles were supported by grant organizations such as Korean National Research Foundation. CONCLUSION: The findings of the analysis show an improvement in the scientific quality with a diversity of articles in Child Health Nursing Research.

Periodontal disease is one of the most common chronic inflammatory diseases in the oral cavity, and this is the leading cause of loss of teeth. Studies on the association between diet and periodontal diseases are very limited. The purpose of this study was to investigate the association between food and nutrient intakes and the prevalence of periodontitis. Subjects were 13,391 adults participating in the 2008-2010 Korea Health and Nutrition Examination Survey. Periodontitis was diagnosed by dentists using the Community Periodontal Index. Nutrient intakes were estimated by the 24-hour dietary recall. Consumption frequencies of foods were from the food frequency questionnaire. Subjects were categorized into 'smoking' or 'non-smoking' groups. Multiple logistic regression analysis was applied to determine the association between diet and periodontitis. The proportions of subjects having periodontitis were 26% in the non-smoking group and 37.5% in the smoking group. In the non-smoking group, intakes of fruits, dairy products, green tea, energy and vitamin C were inversely associated with the prevalence of periodontitis, but fish and coffee intakes were positively associated with the prevalence of periodontitis after adjusting for covariates. In the smoking group, protein and retinol intakes were inversely associated with the prevalence of periodontitis after adjusting for covariates. These results suggest that certain food and nutrient intakes such as fruits, dairy products, green tea, vitamin C, protein, or retinol intakes may affect the prevalence of periodontitis among Korean adults. Further studies are required to confirm these findings in other research settings.

PURPOSE: The purpose of this study was to identify the correlation of critical thinking disposition and problem solving process, and the simulation-based assessment of clinical competence based on a survey of college nursing students. METHODS: In this descriptive correlation study, data for 214 nursing students were analyzed using t-test and Pearson correlation coefficients. RESULTS: Critical thinking disposition, problem solving process, and simulation-based assessment of clinical competence averaged 3.76+/-0.46 (out of 5), 3.67+/-0.47 (5), and 1.51+/-0.17 (2), respectively. A significant difference in scores for simulation-based assessment of clinical competence was found between the high-scoring group and low-scoring group in critical thinking disposition. A significant positive correlation was found between critical thinking disposition and nursing assessment, a sub-domain of clinical competence. CONCLUSION: The results suggest that success in simulation-based learning requires critical thinking disposition in the nursing students, and their critical thinking disposition plays a positive role in nursing assessment, which evaluates the patient's status in a complex situation. Simulation-based learning programs help assess the students' levels in their clinical judgement and performance, and identify their strengths and weaknesses so that the instructor can evaluate and improve the current teaching method.

Spontaneous nystagmus is a reflection of tonic left-right vestibular asymmetry. It is typically seen after a recent unilateral peripheral vestibular lesion and has fast phases away from the side of the lesion. Sometimes spontaneous nystagmus is seen in the absence of a recent unilateral peripheral lesion, in which case it provides evidence of a vestibular lesion but does not localize it. We experienced a case of 35-year-old man who had sudden sensorineural hearing loss on the left side with acute onset of vertigo and transient spontaneous nystagmus, which had fast phases away from the side of the sudden deafness, without canal paresis on the bithermal caloric test.

OBJECTIVES: The purpose of this study was to obtain sex- and age-specific reference level for hearing threshold of normal aging in Korean and to determine if the rate of change in pure-tone hearing thresholds differed by sex. METHODS: Subjects were clients who visited the Health Promotion Center, Daegu Fatima Hospital, Daegu, Korea, from January 2004 to September 2005. Pure-tone audiometric measures were obtained from 3,470 subjects who also completed a hearing questionnaire. The slope of a linear regression was used to estimate the rate of change in pure-tone thresholds at 0.25 to 8 kHz for each ear in 214 men and 902 women without past history of otorrhea, usage of ototoxic drugs, head injury, job in noisy environment, and military service. RESULTS: Hearing thresholds were elevated with age in all test frequencies. Significant sex differences were found in pure-tone thresholds at 4 and 8 kHz after adjusting for age using analysis of covariance. In those high frequencies, hearing was worse in men than in women. The average rate of change in threshold was 0.28 and 0.24 dB per year at 0.25 kHz, increasing gradually to 1.27 and 1.05 dB per year at 8 kHz for men and women, respectively. Men had significantly faster rates of threshold increase at 4 and 8 kHz than women. CONCLUSION: These cross-sectional measures of hearing levels and rate of threshold increases at 4 and 8 kHz showed significant sex differences in Korean men and women with little evidence of noise-induced hearing loss.

Recessive mutations of the SLC26A4 (PDS) gene on chromosome 7q31 can cause sensorineural deafness with goiter (Pendred syndrome, OMIM 274600) or NSRD with goiter (at the DFNB4 locus, OMIM 600791). H723R (2168A>G) is the most commonly reported SLC26A4 mutations in Korean and Japanese and known as founder mutation. We recently experienced one patient with enlarged vestibular aqueduct syndrome. The genetic study showed H723R homozygous in the proband and H723R heterozygous mutation in his family members. The identification of a disease-causing mutation can be used to establish a genotypic diagnosis and provide important information to both families and their physicians.
