Purpose: The purpose of this cross-sectional study was to assess the nutritional states and investigate the energy intake of tube-fed patients with severe neurodevelopmental disability. Methods: Eighty six tube-fed patients with severe neurodevelopmental disability were studied. Heights were measured by flexible scale segmentally. Nutritional parameters of weight, triceps skinfold thickness and mid-arm circumference were also measured. Total caloric intakes through the tube were calculated. Results: The anthropometric results showed that nutritional states of tube-fed patients with severe neurodevelopmental disability were poor. The mean daily caloric intake was much less than daily energy requirement (mean=45.2% of requirement). The caloric intake was 7.2 kcal/height (cm), 57.0 kcal/weight (kg). Height was more related with caloric intake (r=0.476) than weight (r=0.263). Conclusion: These results provide that tube-fed patients with severe neurodevelopmental disability were growth retarded and their energy intakes were much less than daily energy requirements. The preliminary evidence was that they need adequate nutritional supply.

Purpose : The most important management of congenital hydronephrosis consists of the early diagnosis and evaluation of the pathologic abnormalities of congenital hydronephrosis. This study was conducted to investigate the different causes of hydronephrosis and its clinical outcome. Methods : 54 live neonates who were hospitalized and diagnosed with congenital hydronephrosis at Chungnam National University Hospital from Aug. 1998 to Aug. 2003 were retrospectively analyzed. Results : Hydronephrosis(renal pelvic AP diameter $gt;5 mm) was postnatally detected in 54 cases(2.1%) among 2,539 neonates who were hospitalized from Aug. 1998 to Aug. 2003. There were three times more males than females. Additional imaging studies revealed that ureteropelvic junction obstruction was the most common postnatal diagnosis(48.7%), followed by multicystic dysplastic kidney, vesicoureteral reflux and duplication kidney with ureterocele. Spontaneous regression of hydronephrosis was revealed in 25 renal units(75.8% ) of mild hydronephrosis, 14 renal units of moderate hydronephrosis and 1 renal unit of severe hydronephrosis. Operative correction were carried out in 14 renal units(70%) of severe hydronephrosls. Conclusion : The most common established cause of congenital hydronephrosis in this study was ureteropelvic junction obstruction. There are many cases of spontaneous regression in mild to moderate congenital hydronephrosis. Urinary tract infections occur in many neonates with hydronephrosis. Therefore, early detection and evaluation of congenital hydronephrosis and continuous follow-up at regular intervals are necessary for conservation of renal function.

This study aimed to analyze the characteristics and problems of the quasi-market for welfare technology in the long-term care service area in South Korea. The qualitative interviews to the developers of welfare technology were conducted. The main results are as follows. First, the long-term care insurance (LTC) in South Korea has helped to create the limited amount of the effective demands for welfare equipments with low technology. Second, the systemic features of the LTC, however, have constraint the quantitative expansion as well as qualitative growth of the quasi-market for welfare technology. The low level of financial support combined with strict regulations has obstructed qualitative competition in the market. Third, they tend to develop the standardized and minimum welfare equipments for the serious needy for long-term care instead of welfare technology promoting independency of the elderly. Based on the results, this study provided the predictions for the growth of welfare technology and suggested some policy implications.

Objectives : The aim of this study is to investigate correlation between degree of white matter hyperintensities (WMH) and neurocognitive function along with behavioral and psychological symptoms of dementia (BPSD) in Korean patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI). Methods : Participants were 115 elderly subjects diagnosed with Alzheimer's disease or mild cognitive impairment in this retrospective study. WMH in brain MRI were rated with standardized visual rating scales (Fazekas scales) and the subjects were divided into two groups according to Fazekas scale. Cognitive function was evaluated with Korean version of the consortium to establish a registry for Alzheimer's Disease (CERAD-K), and BPSD was evaluated with Korean neuropsychiatric inventory (K-NPI). Independent t-test was performed to analyze the relationship between the degree of WMH and neurocognitive functions & BPSD. Results : Especially, the group with high severity of WMH showed significantly lower language fluency (p<0.05). In addition, the group with high severity of WMH showed significantly higher score in K-NPI. Conclusions : There was a significant association between WMH and neurocognitive test related with executive function. Moreover, WMH seems to affect BPSD severity. Evaluation of WMH would provide useful information in clinical settings.

The objective of this study is to verify the moderated mediating effects according to the severity level of a disability as well as the mediating effects of job security in the relationship between difficulties in the workplace of the disabled wage workers caused by the COVID-19 pandemic and their life satisfaction. As a result of analysis using SPSS ver. 25 and PROCESS macro, the difficulties within the workplace caused by the COVID-19 pandemic had a negative influence on life satisfaction through the job security of the disabled wage worker. In other words, it was revealed that the level of difficulties being faced by the disabled wage workers, which were caused by the COVID-19 pandemic, hinders their life satisfaction through job security. In addition, no moderating effect according to the severity level of disability was identified in the relationship between these variables. This is translated that difficulties in the workplace caused by the COVID-19 pandemic reduce job security and life satisfaction of the disabled wage workers regardless of the severity level of the disability. Based on the results thus far, this study further discussed the institutional implications for promoting the job security and life satisfaction of the disabled wage workers under the COVID-19 pandemic situation.

Atopic dermatitis is a chronic, recurrent, inflammatory skin disease that is a well-known allergic disease with severe itching, making daily life difficult. Since the immunomodulatory action of vitamin D has been reported, several researchers have attempted to determine the correlation between vitamin D and atopic dermatitis. In this review, 41 articles meeting the inclusion criteria were selected and reviewed from the articles published to date. Several studies have reported that low vitamin D levels are associated with the onset of atopic dermatitis and severe atopic dermatitis, but the opinions remain conflicting. Similarly, there are conflicting opinions on the improvement effect of oral vitamin D supplementation on atopic dermatitis, but some possibilities have been suggested. To apply vitamin D as a therapeutic agent for atopic dermatitis, a more systematically designed experiment should be conducted, and an appropriate intake dose for an immunomodulatory function should be obtained.

Purpose: The purpose of this study is to evaluate the relationship between removable denture and depression. This study aims to investigate the relationship between depression and each group by dividing them into a group that were using removable dentures and a group that needed removable dentures but were not using removable dentures. Materials and methods: This study was conducted using raw data from the 7th Korea National Health and Nutrition Examination Survey (KNHNES). By using variables related to the state of the prosthesis and the need for prosthesis among oral examination data, the oral examination data were classified into two groups; group using removable denture and group in need of removable dentures. In addition, the variables of depression were classified into normal (0-4), mild depression (5-9), moderate depression (10-19), and severe depression (20-27) using the values of PHQ-9. For statistical analysis, logistic regression analysis was performed using SAS 9.4. Results: In the group in need of removable dentures, the risk of severe depression was statistically and significantly higher than the group using removable dentures. Conclusion: In patient who have lost multiple teeth, rehabilitation of the missing area with removable dental prosthesis is expected to decrease the occurrence of severe depression.

The purpose of this study was to investigate the temperament characteristics associated with stuttering subtypes (persistent and recovered) over time and the relationship between those characteristics and stuttering severity. This four-year longitudinal study covered 41 preschool children who stutter (CWS) and 30 preschool children who do not stutter (the CWNS group). At the final visit, 27 CWS were classified as the Recovered group and 14 CWS were classified as the Persistent group. Using the Children's Behavior Questionnaire-Short Form, each participant's temperament characteristics were measured twice: at one year and two years after the initial visit. The three subscale scores (Extraversion, Negative Affectivity, and Effortful Control) and the 15 component scores were analyzed, and they were used for between-group and between-visit comparisons. The Persistent group showed a significantly higher Negative Affectivity subscale score at every visit than the Recovered and CWNS groups. Within this subscale, significant group differences were found in the 'Fear' and 'Anger/Frustration' components, demonstrating that the Persistent group scored higher than the Recovered and CWNS groups. There was no significant correlation between the subscale and component scores and the stuttering severity scores within the Persistent group at any visit. These results support the proposition that these two stuttering subtypes have different temperament characteristics; they also imply that temperament might be influenced by stuttering experience over time.

Objective : This study analyzed the correlation between cognitive function and oral health-related quality of life (OHQoL). Methods : Demographic and clinical characteristics were extracted and utilized for subjects aged 45 years or older who participated in the 8th Korean Longitudinal Study on Aging in 2020. The dependent variable was the Geriatric Oral Health Assessment Index, and the independent variable was the level of cognitive function classified by the Mini-Mental State Examination scores. The analysis method used inverse probability of treatment weighting (IPTW). Then, the association between cognitive function and OHQoL was analyzed by multiple regression analysis. Results : Among the participants, 4,367 (71.40%) had normal cognition, 1,155 (18.89%) had moderate cognitive impairment, and 594 (9.71%) had severe cognitive impairment. As a result of analysis by applying IPTW, there was a negative correlation between the cognitive function group and OHQoL (normal vs. moderate: β = -2.534, p < .0001; normal vs. severe: β = -2.452, p < .0001). Conclusion : After propensity score matching, mild cognitive impairment showed a more negative association than severe cognitive impairment. Therefore, patients with cognitive impairment require oral health management education to improve OHQoL regardless of the level of cognitive impairment.

This paper proposes an optimal methodology for automatically diagnosing and predicting the severity of the chronic kidney disease (CKD) using patients' utterances. In patients with CKD, the voice changes due to the weakening of respiratory and laryngeal muscles and vocal fold edema. Previous studies have phonetically analyzed the voices of patients with CKD, but no studies have been conducted to classify the voices of patients. In this paper, the utterances of patients with CKD were classified using the variety of utterance types (sustained vowel, sentence, general sentence), the feature sets [handcrafted features, extended Geneva Minimalistic Acoustic Parameter Set (eGeMAPS), CNN extracted features], and the classifiers (SVM, XGBoost). Total of 1,523 utterances which are 3 hours, 26 minutes, and 25 seconds long, are used. F1-score of 0.93 for automatically diagnosing a disease, 0.89 for a 3-classes problem, and 0.84 for a 5-classes problem were achieved. The highest performance was obtained when the combination of general sentence utterances, handcrafted feature set, and XGBoost was used. The result suggests that a general sentence utterance that can reflect all speakers' speech characteristics and an appropriate feature set extracted from there are adequate for the automatic classification of CKD patients' utterances.
