PURPOSE: Early diagnosis of congenital hearing loss through the neonatal hearing screening test minimizes language defect. This research intends to identify frequency of congenital hearing loss in infants through neonatal hearing screening test with the aim of communicating the importance of hearing test for infants. METHODS: From May 20, 2003 to May 19, 2004, infants were subjected to Automated Auditory Brainstem Response test during one month of birth to conduct the test with 35 dB sound. Infants who passed the 1st round of hearing test, were classified into 'pass' group whereas those who did not were classified into 'refer' group. Infants who did not 'pass' in the hearing test conducted within one month of birth were subjected to re-test one month later, and if classified as 'refer' during the re-test, they were subjected to the diagnosis for validation of hearing loss by requesting test to the hearing loss clinic. RESULTS: There was no difference among the 'pass' and 'refer' group in terms of form of childbirth, weight at birth and gestational age. In the 1st test, total of 45 infants were classified into 'refer' group. Six among 35 who were subjected to re-test (17%) did not pass the re-test, and all were diagnosed with congenital hearing loss. This corresponds to 0.35% (3.5 per 1, 000) among total number of 1, 718 subjects. CONCLUSION: In our study the congenital hearing loss tends to be considerably more frequently than congenital metabolic disorder. Accordingly, newly born infants are strongly recommended to undergo neonatal hearing screening test.

Failure of fixed implant supported prosthesis is caused by biomechanical factors such as excessive occlusal stress and biological factors such as bacterial infections andinflammation. Implants with severe bone resorption that have worsened without being resolved due to implant complications should be removed and then new treatmentsshould be planned, taking into account remaining teeth, remaining implants, and residual alveolar. The patient of this case removed some of fixed implant prosthesis of mandible.The condition of the remaining alveolar bone was reassessed for further implant replacement and a few implants were placed. Then implant assisted removable partialdenture (IAPRD) treatment is performed using implant surveyed bridge as abutment. Through this treatment, the clinical results were satisfactory on aspect of masticatoryfunction recovery and oral hygiene management. (J Korean Acad Prosthodont 2020;58:161-8)

PURPOSE: This integrative review was done to explore trends in mental health nursing research on women in terms of a research paradigm, life-cycles of the women, and mental health concepts. METHODS: n this study an examination was done of the literature on mental health of women described in nursing research published in major Korean nursing journal databases from 2000 to 2012. The Journal of Child Health Nursing was excluded. The MeSH search terms included 'nursing' and 'woman' and 282 articles were included in the final review. RESULTS: Postpositivism was the most predominantly used paradigm. Middle aged women were studied more often and older and reproductive aged women were less likely to be studied compared to their percentage of the total population. Researchers focused most on depression, followed by sleep disorders and anxiety disorders. CONCLUSION: The study results indicate a need for rmfjtunursing researchers to utilize various research paradigms when conducting nursing research and demonstrate paradigm utility. Researchers should also pay more attention to older and reproductive aged women, and to anxiety disorders.

OBJECTIVES: The purposes of this study were to identify the factors that affect the health-related quality of life (HRQoL) of the elderly with chronic diseases and to subsequently develop from such factors a prediction model to help identify HRQoL risk groups that require intervention. METHODS: We analyzed a set of secondary data regarding 716 individuals extracted from the Korea National Health and Nutrition Examination Survey from 2008 to 2010. The statistical package of SPSS and MATLAB were used for data analysis and development of the prediction model. The algorithms used in the study were the following: stepwise logistic regression (SLR) analysis and machine learning (ML) techniques, such as decision tree, random forest, and support vector machine methods. RESULTS: Five factors with statistical significance were identified for HRQoL in the elderly with chronic diseases: 'monthly income', 'diagnosis of chronic disease', 'depression', 'discomfort', and 'perceived health status.' The SLR analysis showed the best performance with accuracy = 0.93 and F-score = 0.49. The results of this study provide essential materials that will help formulate personalized health management strategies and develop interventions programs towards the improvement of the HRQoL for elderly people with chronic diseases. CONCLUSIONS: Our study is, to our best knowledge, the first attempt to identify the influencing factors and to apply prediction models for the HRQoL of the elderly with chronic diseases by using ML techniques as an alternative and complement to the traditional statistical approaches.

OBJECTIVES: The present study takes part of the agricultural district cohort study of a certain county located in Gyeonggido and aims to investigate the difference of the heart rate variability(HRV) according to the social support level. METHODS: We used data from 1727 participants of a health promotion program who are older than 40 years old. A physical examination, as well as a one-to-one interview to obtain sociodemographic characteristics, was performed with each participant. In addition, the participants completed the Medical Outcomes Study-Social Support Survey(MOS-SSS) for their the social support level to be assessed, and their HRV were measured to evaluate their autonomic function. The entire group was divided in two groups according to its MOS-SSS points to facilitate the research. Those who were evaluated as the high 25%(432 persons) were denominated as high social support (HSS) group and those who were evaluated as the low 25%(425 persons) were denominated as poor social support(PSS) group. RESULTS: The two groups showed significant differences on the sociodemographic factor such as mean age and gender composition(p<0.05). Comparing the indices related to the HRV, the HSS group had the following values higher than the PSS group : SDNN(F=4.938, p=0.027), TP(F=8.088, p=0.005), VLF(F=6.220, p=0.013) LF (F=3.873, p=0.049). CONCLUSION: According to the research, the PSS group showed dysfunction on their autonomic nervous system comparing to the HSS group. The social support helps an individual overcome difficulties, helps the adaptation during the changes of circumstances and in stressful situations it serves like a buffer. Based on that, it's possible to define that a low social support level gave an impact on the autonomic function. Also, using the fact that the HRV can evaluate the autonomic function in an objective view, it was possible to visualize that it has a potential to be used as an assistant factor to evaluate the social support.

PURPOSE: To evaluate radiological and clinical results of the antegrade intramedullary prebent K-wire fixation for the 5th metacarpal neck fracture. MATERIALS AND METHODS: Between January, 2006 and December, 2009, 31 patients with displaced neck fracture of the fifth metacarpal who received antegrade intramedullary prebent K-wire fixation were included in this study. Radiological and clinical outcome evaluations were performed. RESULTS: All the fractures were completely united. In the oblique radiographs, the average of preoperative angulation was corrected from 38.9degrees to 4.4degrees. The average difference between postoperative and final follow-up was 1.2degrees. Clinical outcomes were satisfactory except for one patient who had sustained ulnar nerve dorsal branch injury during surgery. CONCLUSION: Antegrade intramedullary prebent K-wire fixation may be preferentially considered as one of the best ways to fix the displaced neck fractures of the fifth metacarpal.

OBJECTIVES: This study was conducted to provide data for the establishment of a practical and the effective exercise program for managing the musculoskeletal symptoms of workers who are employed in small and medium sized enterprises. METHODS: The risk factors related to musculoskeletal disease management were chosen according to the relevant literatures, and were based on advise from experts on the Delphi method. Questionnaires on selected risk factors (with a 5-point Likert scale) were given to 785 subjects who worked in small and medium sized enterprises. The subjects were then classified in the risk group when they had the symptoms and recorded at least 3 points. From those subjects in the risk group, those who had both work-related factors and general characteristics factors (with an average of at least 3 points) were further classified as the high risk group. We performed a 12-week musculoskeletal exercise program for the low and high risk groups to analyze their changes in symptoms and complaints in order to estimate the effectiveness of the exercise program. RESULTS: Out of 785 subjects, 454(57.8%) were in the risk group of musculoskeletal diseases and 121(15.4%) were in the high risk group. According to multiple logistic regression analysis of the factors for the musculoskeletal symptoms in the low risk group, the significant risk factors were sex and personal disease related with musculoskeletal disease, while the risk factors in the high risk group were age, sex, and personal disease related with musculoskeletal disease. After the 12-week exercise program was performed by the low risk group, the number of musculoskeletal symptom complaints in the control group did not significantly changed, whereas for the intervention group, the number of musculoskeletal symptom complaints significantly declined for all parts of the body. After the 12-week exercise program performed by the high risk group, the number of musculoskeletal symptom complaints in the control group was significantly enhanced for the arm and elbow parts. In the intervention group, the complaint rate for musculoskeletal symptoms significantly declined only for the low back. CONCLUSION: The musculoskeletal symptoms were significantly improved by the exercise program in the low risk group, but not in the high risk group. It is suggested that control measures on administrative and/or work related factors, in addition to the exercise program should be considered simultaneously for the control of musculoskeletal symptoms in groups at high risk of musculoskeletal disease.

Purpose:
The aim of this study was to evaluate the effects of four surface treatment methods to improve zirconia roughness and three types of resin cement on the shear bond strength (SBS).
Materials and methods:
A total of 120 zirconia blocks were randomly divided into four surface treatments: non-treatment (Control), airborne-particle abrasion (APA) with 50 μm Al2O3 (APA50), APA with 125 μm Al2O3(APA125), and ZrO2 slurry (ZA). Three resin cements (Panavia F 2.0, Superbond C&B, and Variolink N) were applied to the surface-treated zirconia specimens. All specimens were subjected to SBS testing using a universal testing machine. The surface of the representative specimens of each group was observed by scanning electron microscope (SEM). SBS data were analyzed with oneway ANOVA, two-way ANOVA test and post-hoc Tukey HSD Test (α=.05).
Results:
In the surface treatment method, APA125, APA50, ZA, and Control showed high shear bond strength in order, but there was no significant difference between APA125 and APA50 (P >.05). Also, ZA showed significantly higher shear bond strength than Control (P <.05). In the resin cement type, Panavia F 2.0, Superbond C&B, and Variolink N showed significantly higher shear bond strength in order (P <.05). In SEM images, the zirconia surfaces of the APA50 and APA125 showed quite rough and irregular shapes, and the zirconia surface of the ZA was observed small irregular porosity and rough surfaces.
Conclusion
APA and ZrO 2 slurry were enhanced the surface roughness of zirconia, and Panavia F 2.0 containing MDP showed the highest shear bond strength with zirconia.
