Factors affecting the transition to adulthood of Korean young adults with spina bifida: a qualitative study.

BACKGROUND: Transition to adulthood to live independently while self-managing health and daily life without parental help is crucial for young adults with chronic conditions. Despite its importance as a precursor to effectively managing lifelong conditions, little is known about the experiences of young adults with spina bifida (SB) in transition to adulthood in Asian countries. This study aimed to explore the experiences of Korean young adults with SB to identify the facilitators or barriers to the transition from adolescence to adulthood from their perspectives. METHODS: This study used a qualitative descriptive design. The data were collected in South Korea through three focus group interviews with 16 young adults with SB, aged 19-26, from August to November 2020. We conducted a qualitative content analysis using a conventional approach to identify the factors that facilitated and hindered the participants' transition to adulthood. RESULTS: Two themes emerged as facilitators and barriers to the transition to adulthood. a) Facilitators: understanding and acceptance of SB, acquiring self-management skills, parenting styles encouraging autonomy, parents' emotional support, school teachers' thoughtful consideration, and participation in self-help groups. b) Barriers: overprotective parenting style, experience of being bullied by peers, damaged self-concept, concealing one's chronic condition from others, and the lack of privacy in school restrooms. CONCLUSIONS: Korean young adults with SB shared their experiences of struggling to properly manage their chronic conditions on their own, particularly concerning regular bladder emptying, during the transition from adolescence to adulthood. To facilitate the transition to adulthood, education on the SB and self-management for adolescents with SB and on parenting styles for their parents are important. To eliminate barriers to the transition to adulthood, improving negative perceptions of disability among students and teachers and making school restrooms CIC-friendly are needed.

Factors Associated With Media Addiction in Korean Elementary School Children.

The aim of this study was to identify the prevalence of media addiction and its associated factors in elementary school children based on the problem behavior theory. This cross-sectional study was a secondary data analysis using national data from the 10th Panel Study on Korean Children 2017, which included 1,078 families of third-grade students (8-9 years of age). Descriptive statistics were used to examine the prevalence of media addiction, and logistic regression analysis was conducted to identify factors associated with media addiction. Prevalence of media addiction was 22.91% in this sample. Media addiction was significantly associated with general characteristics (gender, education level of mother, and time spent without parents), socialization (media use time), factors in the personal system (happiness), and factors in the perceived-environment system (parenting style). More comprehensive, tailored education may prevent elementary school children's media addiction. In addition, parents should participate in media addiction education with their children.

Nurse-led eHealth transition care program for adolescents with spina bifida: A feasibility and acceptability study.

PURPOSE: This study aimed to evaluate the feasibility and acceptability of a nurse-led eHealth transition care program for adolescents with spina bifida. DESIGN AND METHODS: This study used a single-arm, pretest-posttest intervention study. Adolescents with spina bifida, aged 12-15 years, and their parents participated in the program. A 6-week program was delivered through an online platform in real-time by nurses. We evaluated feasibility and acceptability using criteria such as the completion rate, program satisfaction, changes in transition readiness, social support, career preparation behavior, sexual knowledge, and sexual worries at three time points from July to September 2021. RESULTS: Thirteen adolescents completed all sessions and surveys (13/14, 92.9%). All adolescents expressed high satisfaction with both the content and delivery methods of the program. Significant benefits in transition readiness, career preparation behavior, and sexual knowledge were identified over the study period. However, the evaluation of social support and sexual worries did not demonstrate any significant improvements. Additionally, through family counseling, adolescents benefited from experiences such as reflecting on their current transition readiness, setting and achieving individualized goals and plans using a self-checklist with their parents and nursing professionals. CONCLUSION: This nurse-led eHealth intervention was feasible and acceptable for adolescents with spina bifida. Furthermore, our results highlight the practicability and the potential for strategic dissemination of using this eHealth program in transitional care during the COVID-19 pandemic. PRACTICE IMPLICATIONS: The eHealth transition care program contributes to broadening existing nursing interventions not only in medical areas but also in daily life areas.

Transition programs for adolescents and young adults with spina bifida: A mixed-methods systematic review.

AIMS: To identify the components of transition programs for the successful transition of adolescents and young adults with spina bifida and to synthesize the literature findings on the transition outcomes of the programs. DESIGN: Mixed-methods systematic review. DATA SOURCES: PubMed, CINAHL, PsycINFO, and Web of Science (January 2010-June 2019). REVIEW METHODS: The methodological quality was appraised using the Mixed Methods Appraisal Tool and Cochrane Risk of Bias Tool. Extracted data were summarized as tables. For data synthesis, a sequential explanatory design was used. RESULTS: Eight studies were selected. The main components of the transition programs identified the participants' characteristics and intervention strategies. Quantitative studies reported only positive transition outcomes, including independence and satisfaction with social support and transition experience, whereas negative outcomes such as negative experiences communicating with providers and uncertainty were further reported in qualitative studies. CONCLUSION: For development and implementation of a successful transition program, it is necessary to assess the characteristics and needs of the participants and incorporate their needs with input from parents and trained healthcare providers. IMPACT: When planning transition programs, a comprehensive effort that encompasses program development, implementation, and evaluation, based on developmental tasks and long-term perspectives, is needed. Transition program that reflect the cultural characteristics of Eastern and developing countries are needed.

Discrepancies in Educational Needs for Transition in Adolescents and Young Adults with Spina Bifida in South Korea: Use of the Borich Needs Assessment Model.

PURPOSE: Transition is an important goal for ensuring that adolescents and young adults (AYAs) with spina bifida (SB) lead autonomous lives. This study aimed to identify the educational needs of AYAs with SB based on the discrepancies between perceived importance and proficiency levels during the transition process. DESIGN AND METHODS: A cross-sectional study was conducted through face-to-face and online surveys from Jan-Dec 2020 of AYAs aged 13-25 years who had previously been diagnosed with SB. The survey consisted of 37 transition-related questions, of which 11 pertained to healthcare environments and 26 pertained to transition education needs SPSS and Excel were used for statistical analysis. Transition educational needs were analyzed by the Borich Needs Assessment Model. Higher the mean weighted discrepancy scores, lower the proficiency as compared to the perceived importance, indicating that the educational needs were high. RESULTS: Overall, 108 responses were analyzed, and 56 (51.9%) AYAs were diagnosed with lipomyelomeningocele. The highest ranked educational needs were for "Health insurance system", "SB related urinary system diseases management", "SB related nervous system symptoms", and "Self-catheterization management". "The demands for 'SB related work life", "Urinary incontinence management", and "Constipation management" were significantly higher in young adults than adolescents. CONCLUSIONS: During the transition process, activities perceived as important by AYAs with SB may differ from the activities that they can actually perform proficiently. It is important to assess their needs based on these discrepancies. PRACTICE IMPLICATIONS: Transition education programs are needed that consider the individual educational needs and developmental stage-specific characteristics of AYAs with SB.

Quality by Design approaches to assessing the robustness of tangential flow filtration for MAb.

Quality by Design (QbD) is a modern approach for quality assurance in pharmaceutical production. This article illustrates a case study of TFF robustness performed for a process characterization of a monoclonal antibody under QbD principles by exploring functional relationships that link the process parameters to quality/process attributes with prior process knowledge, risk assessment, and multivariate experiments. In every case of quality or process attributes, all measured values were in alignment with the allowable specification range, and the developed models were non-significant and had no lack of fit, thus confirming the robustness of the TFF process within the tested ranges of process parameters.

Two-Step Integrative Education Program and mHealth for Korean Children with Spina Bifida: A Quasi-Experimental Pre-Post Study.

PURPOSE: Self-management of the daily tasks associated with condition management is an important goal for children with spina bifida (SB)to achieve for adolescence. This study investigated the effects of a two-step self-management improvement program including an onsite, integrative education program and mHealth on children with SB based on the Individual and Family Self-Management Theory. DESIGN AND METHODS: We used a pretest-posttest, quasi-experimental design with a nonequivalent control group. Open-ended questions were administered to obtain the opinions of the participants and their parents on the intervention program. The intervention effectiveness was evaluated by repeated-measures ANOVA using factors such as school adjustment, self-management knowledge, self-efficacy, self-management behavior, and quality of life measurement in 35 children with SB aged 7-12 years and their parents from July 2018 to October 2018. RESULTS: This intervention program did not result in a significant difference in quantitative outcomes between the experimental and control groups, but qualitatively, the children participating in this study and their parents responded positively to the self-management program. CONCLUSION: The current study demonstrated the potential effectiveness of this self-management program in children with SB. PRACTICE IMPLICATIONS: When healthcare providers develop an intervention for school-going children who are the digital native generation, up-to-date technological interventions, level of motivation of children, and intervention dosage should be taken into consideration.

Evaluation of bond strength of porous cobalt-chromium metal and pressed ceramic fabricated by additive manufacturing.

STATEMENT OF PROBLEM: A high metal-ceramic bond strength is important for successful dental restorations. However, studies on the evaluation of the bond strength of porous metal-ceramic restorations compared with conventional ones are scarce. PURPOSE: The purpose of this in vitro study was to compare the bond strength of a porous metal-ceramic structure with conventional metal-ceramic restorations. MATERIAL AND METHODS: Ten porous specimens were fabricated by selective laser sintering (SLS) according to the International Organization for Standardization 9693-1:2012, 10 specimens without porosity by SLS, and 10 cobalt-chromium (Co-Cr) cast specimens without porosity. The ceramic was applied with the pressing method. A 3-point bend test was performed with a universal testing machine, and the data were statistically analyzed by using 1-way analysis of variance (α=.05). RESULTS: The mean ±standard deviation bond strength of the porous group fabricated by SLS was the lowest (35.6 ±9.1 MPa), that of the group without porosity in the casting method was 43.5 ±7.8 MPa, and that of the group without porosity fabricated by SLS was the highest (47.7 ±4.5 MPa); these were statistically similar (P=.058). CONCLUSIONS: Although the porous structure reported the lowest bond strength among the 3 sets of test specimens, its bond strength was higher than the International Standards Organization standard of 25 MPa.

A 2-Step Integrative Education Program and mHealth for Self-Management in Korean Children with Spina Bifida: Feasibility Study.

PURPOSE: The aim of this study was to develop and test the feasibility of a 2-step self-management program, including onsite integrative education and a mobile health (mHealth) intervention, for children with spina bifida (SB). DESIGN AND METHODS: This feasibility study used a quasi-experimental single group pre-and post-test design. The onsite integrative education and the mHealth program, "Glowing Stars™," were developed and then tested for content validity by a panel of experts. The feasibility and user satisfaction were evaluated using factors such as school adjustment, self-management knowledge, self-efficacy, self-management behavior, and quality of life measurement by children aged 10 to 12 years with SB and their parents, from March 2018 to April 2018. RESULTS: A total of five children with SB completed this intervention. All children perceived that this program was usable and feasible to maintain self-management behavior. A statistically significant difference was observed in the children's self-management behavior domain between the first and second post-test (p = .043). CONCLUSION: This innovative 2-step self-management intervention program complements existing single interventions and confirms the possibility of mHealth technology as an intervention for children with SB. PRACTICE IMPLICATIONS: In pediatric nursing, this innovative intervention could be adapted for children with chronic conditions, with a positive effect on self-management.

Parents' Needs Concerning Their Children with Spina Bifida in South Korea: A Mixed Method Study.

PURPOSE: This study aimed to determine the needs of children with spina bifida (SB) and their families from their parents' perspective in South Korea. DESIGN AND METHODS: This was a convergent mixed methods study design. From December 2016 to February 2017, parents of children with SB participated in a quantitative prospective observational study (N = 164), using the Family Needs Assessment Tool. Qualitative focus group interviews were conducted, according to three developmental stages (N = 15) in May 2017. Integrated analyses were conducted jointly by merging the quantitative and qualitative findings. RESULTS: Quantitative findings revealed very high parental needs in three assessment domains: information, healthcare service/program, and difficulties related to healthcare. Ten qualitative themes were identified in these 3 domains. Quantitative and qualitative methods enabled more extensive findings. Comparison and merging of the data resulted in six confirmed and four expanded findings. In particular, we identified the need for a child-focused self-management program, a bladder/bowel disability awareness program, welfare policies, and partnership with healthcare professionals as the expanded findings. CONCLUSION: This mixed method study provided empirical evidence to help better understand the complex needs of parents of children with SB. PRACTICE IMPLICATIONS: When developing and providing healthcare education and service to families of children with SB, especially, in countries where SB educational programs have not been established yet, it is important to develop them based on their own needs, which may vary based on the child's developmental stage and socio-cultural characteristics.

A comparative study of additive and subtractive manufacturing for dental restorations.

STATEMENT OF PROBLEM: Digital systems have recently found widespread application in the fabrication of dental restorations. For the clinical assessment of dental restorations fabricated digitally, it is necessary to evaluate their accuracy. However, studies of the accuracy of inlay restorations fabricated with additive manufacturing are lacking. PURPOSE: The purpose of this in vitro study was to evaluate and compare the accuracy of inlay restorations fabricated by using recently introduced additive manufacturing with the accuracy of subtractive methods. MATERIAL AND METHODS: The inlay (distal occlusal cavity) shape was fabricated using 3-dimensional image (reference data) software. Specimens were fabricated using 4 different methods (each n=10, total N=40), including 2 additive manufacturing methods, stereolithography apparatus and selective laser sintering; and 2 subtractive methods, wax and zirconia milling. Fabricated specimens were scanned using a dental scanner and then compared by overlapping reference data. The results were statistically analyzed using a 1-way analysis of variance (α=.05). Additionally, the surface morphology of 1 randomly (the first of each specimen) selected specimen from each group was evaluated using a digital microscope. RESULTS: The results of the overlap analysis of the dental restorations indicated that the root mean square (RMS) deviation observed in the restorations fabricated using the additive manufacturing methods were significantly different from those fabricated using the subtractive methods (P<.05). However, no significant differences were found between restorations fabricated using stereolithography apparatus and selective laser sintering, the additive manufacturing methods (P=.466). Similarly, no significant differences were found between wax and zirconia, the subtractive methods (P=.986). The observed RMS values were 106 µm for stereolithography apparatus, 113 µm for selective laser sintering, 116 µm for wax, and 119 µm for zirconia. Microscopic evaluation of the surface revealed a fine linear gap between the layers of restorations fabricated using stereolithography apparatus and a grooved hole with inconsistent weak scratches when fabricated using selective laser sintering. In the wax and zirconia restorations, possible traces of milling bur passes were observed. CONCLUSIONS: The results indicate that the accuracy of dental restorations fabricated using the additive manufacturing methods is higher than that of subtractive methods. Therefore, additive manufacturing methods are a viable alternative to subtractive methods.

Accuracy of zirconia crown manufactured using stereolithography and digital light processing.

OBJECTIVES: The aim of this study is to evaluate the accuracy of zirconia crowns fabricated using stereolithography (SLA) and digital light processing (DLP) and to compare their accuracy with those fabricated using the subtractive manufacturing (SM) method. METHODS: A typodont model with a prepared maxillary first molar was scanned, and the anatomical contour crown was designed using dental computer-aided-design (CAD) software. The designed file in standard tessellation language (STL) format was used to fabricate 10 crowns per group. The crowns were manufactured using a dental milling machine (Datron D5; MLC group), SLA (CERAMAKER 900; SLAC group), and DLP (ZIPRO; DLPC group) printers. The fabricated crowns were scanned using a dental laboratory scanner and saved in three parts: the external, intaglio, and marginal surfaces. For accuracy assessment, these parts were superimposed to the reference file. Root mean square (RMS) values were evaluated using three-dimensional analysis software (Geomagic Control X). Statistical significance was evaluated using a nonparametric Kruskal-Wallis test (α = 0.05) and a post-hoc Mann-Whitney U test with Bonferroni correction (α = 0.016). RESULTS: Trueness evaluation revealed the lowest RMS value in all areas in the MLC group, followed by that in the DLPC group. The precision evaluation revealed the lowest RMS value in all areas in the MLC group. Statistically significant differences were observed among the groups in the external, intaglio, and marginal surface (P < 0.05). CONCLUSIONS: Although the restorations fabricated using SM revealed higher accuracy, the crowns manufactured using SLA and DLP methods were considered clinically acceptable. CLINICAL SIGNIFICANCE: In the production of zirconia crowns, subtractive manufacturing continues to demonstrate significantly higher accuracy compared to additive manufacturing. However, crowns fabricated using the additive manufacturing method also demonstrated high accuracy.

Highly Efficient Ultra-Thin EML Blue PHOLEDs with an External Light-Extraction Diffuser.

In this study, various diffusers are applied to highly efficient ultra-thin emission layer (EML) structure-based blue phosphorescent organic light-emitting diodes (PHOLEDs) to improve the electroluminescence (EL) characteristics and viewing angle. To achieve highly efficient blue PHOLEDs, the EL characteristics of ultra-thin EML PHOLEDs with the various diffusers having different structures of pattern-shape (hemisphere/sphere), size (4~75 µm), distribution (surface/embedded), and packing (close-packed/random) were systematically analyzed. The diffusers showed different enhancements in the overall EL characteristics of efficiencies, viewing angle, and others. The EL characteristics showed apparent dependency on their structure. The external quantum efficiency (EQE) was enhanced mainly by following the orders of pattern, size, and shape. Following the pattern size, the EQE enhancement gradually increased; the largest-sized diffuser with a 75 µm closed-packed hemisphere (diffuser-1) showed a 1.47-fold EQE improvement, which was the highest. Meanwhile, the diffuser with a ~7 µm random embedded sphere with a low density (diffuser 5) showed the lowest 1.02-fold-improved EQE. The reference device with ultra-thin EML structure-based blue PHOLEDs showed a maximum EQE of 16.6%, and the device with diffuser 1 achieved a maximum EQE of 24.3% with a 5.1% wider viewing angle compared to the reference device without a diffuser. For the in-depth analysis, the viewing angle profile of the ultra-thin EML PHOLED device and fluorescent green OLEDs were compared. As a result, the efficiency enhancement characteristics of the diffusers show a difference in the viewing angle profile. Finally, the application of the diffuser successfully demonstrated that the EL efficiency and viewing angle could be selectively improved. Additionally, we found that it was possible to realize a wide viewing angle and achieve considerable EQE enhancement by further investigations using high-density and large-sized embedded structures of light-extraction film.

Enhancing Light Extraction Efficiency in OLED Using Scattering Structure-Embedded DMD-Based Transparent Composite Electrodes.

This study investigates the application of scattering structures to the metal layer in a DMD (Dielectric/Metal/Dielectric) configuration through plasma treatment. The purpose is to enhance the light extraction efficiency of organic light-emitting diodes (OLEDs). Different plasma conditions were explored to create scattering structures on the metal layer. The fabricated devices were characterized for their electrical and optical properties. The results demonstrate that the introduction of scattering structures through plasma treatment effectively improves the light extraction efficiency of OLEDs. Specifically, using O2-plasma treatment on the metal layer resulted in significant enhancements in the total transmittance, haze, and figure of merit. These findings suggest that incorporating scattering structures within the DMD configuration can effectively promote light extraction in OLEDs, leading to enhanced overall performance and light efficiency.

Doping-Free Phosphorescent and Thermally Activated Delayed Fluorescent Organic Light-Emitting Diodes with an Ultra-Thin Emission Layer.

We report the electroluminescence (EL) characteristics of blue ultra-thin emissive layer (U-EML) phosphorescent (PH) organic light-emitting diodes (OLED) and thermally activated delayed fluorescence (TADF) OLED. A variety of transport layer (TL) materials were used in the fabricated OLEDs. The well-known FIrpic and DMAC-DPS were used with a thickness of 0.3 nm, which is relatively thicker than the optimal thickness (0.15 nm) of the blue phosphorescent ultra-thin emissive layer to ensure sufficient energy transfer. While FIrpic showed overall high efficiency in various TLs, DMAC-DPS exhibited three times lower efficiency in limited TLs. To clarify/identify low efficiency and to improve the EL, the thickness of DMAC-DPS was varied. A significantly higher and comparable efficiency was observed with a thickness of 4.5 nm, which is 15 times thicker. This thickness was oriented from the TADF itself, which reduces quenching in a triplet-triplet annihilation compared to the PH process. The thinner optimal thickness compared with ~30 nm of fluorescent OLEDs suggests that there still is quenching taking place. We expect that the efficiency of TADF U-EML OLEDs can be enhanced through further research on controlling the exciton quenching using multiple U-EMLs with spacers and a novel material with a high energy transfer rate (ΔES-T).

Fabrication of Flexible PDMS Films with Micro-Convex Structure for Light Extraction from Organic Light-Emitting Diodes.

In this study, we demonstrated organic light-emitting diodes (OLEDs) outcoupling with a flexible polydimethylsiloxane (PDMS) film with a micro-convex structure using the breath figure (BF) method. We can easily control the micro-convex pattern by adjusting the concentration of polystyrene and the humidity during the BF process. As process conditions to fabricate the micro-convex structure, polymer concentrations of 10, 20, 40, and 80 mg/mL and 60, 70, and 80% relative humidity were used. To evaluate the optical properties, we analyzed the transmission, diffusion, and electroluminescence with or without the micro-convex structure on the OLEDs. The shape and density of the micro-convex structure are related to its optical properties and outcoupling and we have experimentally demonstrated this. By applying a micro-convex structure, it achieved up to a 42% improvement in the external quantum efficiency compared to bare OLEDs (without any light extraction film). We expect the fabricated flexible light extraction film to be effective for outcoupling and applicable to flexible devices.

Cross-cultural adaptation and validation of the Korean version of the quality of life assessment in spina bifida for children (QUALAS-C-K).

PURPOSE: This study aimed to translate and cross-culturally adapt the QUAlity of Life Assessment in Spina bifida for Children (QUALAS-C) and validate the Korean version of the QUALAS-C (QUALAS-C-K). MATERIALS AND METHODS: Three urologists translated the QUALAS-C into Korean. Facial and content validity were assessed in the pilot study. Back-translation into English was performed. In the main study, the QUALAS-C-K and Korean version of KIDSCREEN-27 were administered simultaneously. Test-retest reliability was confirmed by re-administering the QUALAS-C-K. Internal consistency was verified using Cronbach's alpha. Factor analysis was performed, and convergent and divergent validity were demonstrated using the Korean version of KIDSCREEN-27. RESULTS: A total of 53 children with spina bifida participated in the main study. Cronbach's alpha for the overall instrument determined good internal consistency (0.72-0.85), the intraclass correlation coefficient showed good stability (0.74-0.77), and the factor analysis converged to the same two-factor structure as in the original version. Construct validity revealed weak-to-moderate associations (r ≤ 0.57) between QUALAS-C-K and K-KIDSCREEN-27, indicating that QUALAS-C-K measures different aspects of the HRQOL than K-KIDSCEEN-27. CONCLUSIONS: The QUALAS-C-K is a reliable and valid instrument for assessing the health-related quality of life of children with SB in Korea.IMPLICATIONS FOR REHABILITATIONHealth-related quality of life (HRQOL) is an important patient-reported outcome among children with spina bifida (SB).The QUAlity of Life Assessment of Spina bifida for Children (QUALAS-C) is a self-reported, age-appropriate, and condition-specific HRQOL questionnaire for children with SB, developed in the United States.Our study demonstrated that the Korean version of the QUAlity of Life Assessment of Spina bifida for Children (QUALAS-C-K) is a valid and reliable tool.The QUALAS-C-K is a succinct and valuable questionnaire that can be used to assess HRQOL of children with SB, particularly focusing on bladder and bowel problems in clinical practice and research.

Translation and validation of the Korean version of the QUAlity of Life Assessment in Spina bifida for Teenagers (QUALAS-T-K).

PURPOSE: The Quality of Life Assessment in Spina bifida for Teenagers (QUALAS-T) is a tool used to evaluate health-related quality of life (HRQOL) in adolescents with spina bifida (SB). The purpose of this study was to translate the QUALAS-T into Korean and validate its Korean version (QUALAS-T-K). METHODS: Translation and validation processes were carried out in accordance with a specified protocol, including forward and back translation, a content validity study, and a main study. The tool's reliability was evaluated based on its internal consistency and stability. Factor analysis was conducted, and convergent validity was confirmed using the KIDSCREEN-27. RESULTS: Of the 59 participants, 35 had lipomyelomeningoceles. Confirmatory factor analysis confirmed that QUALAS-T-K had the same structure as QUALAS-T. The QUALAS-T-K showed excellent internal consistency (α: 0.872-0.893, ω: 0.875-0.885), test-retest reliability (ICC:0.84-0.92), and weak to strong correlations with the KIDSCREEN-27. CONCLUSIONS: The QUALAS-T-K, developed by reflecting on the characteristics of SB and considering the applicability of Korean cultural characteristics and clinical practice, is a convenient and reliable tool with excellent internal consistency and stability. This could be a useful tool in clinical and research settings for HRQOL evaluation of adolescents with SB.Implications for RehabilitationOptimizing health-related quality of life (HRQOL) is one of the goals of individuals with spina bifida (SB), and HRQOL measures that reflect the condition specificity of SB should be performed.The QUAlity of Life Assessment in Spina bifida for Teenagers (QUALAS-T), developed in the USA, is a self-reported HRQOL questionnaire used in research and clinical practice for adolescents with SB.This study revealed that the QUALAS-T, translated into Korean, is a valid, convenient, and reliable tool.The Korean version of the QUALAS-T is a useful tool that can be used in clinical and research settings to optimize HRQOL in adolescents with SB.

Quantitative and qualitative evaluation on the accuracy of three intraoral scanners for human identification in forensic odontology.

The purpose of this study was to analyze the accuracy of intra oral scanner (IOS) to confirm the applicability of IOS for the recording and analysis of tooth morphology in forensics. The less damaged mandible specimen with many teeth remaining was scanned three times using three types of intraoral scanners (CS3600, i500, and Trios3). For quantitative comparisons of the scanned images produced by these intraoral scanners, root mean square (RMS) values were computed using a three-dimensional analysis program and a one-way ANOVA was conducted with Tukey HSD (honestly significant difference) as a post-hoc analysis (α=0.05). The repeatability of the full scan data was highest with the i500 (0.14±0.03 mm), and the post-hoc analysis confirmed significant differences between the CS3600 and the i500 outcomes (P-value=0.003). The repeatability of the partial scan data for the teeth in the mandible was highest with the i500 (0.08±0.02 mm), and the post-hoc analysis confirmed significant differences between the CS3600 and the i500 (P-value=0.016). The precision of the full scan data was highest with the i500 (0.16±0.01 mm) but the differences were not statistically significant (P-value=0.091). Meanwhile, the precision of the partial scan data for the teeth in the mandible was highest with the Trios3 (0.22±0.02 mm), but the differences were not statistically significant (P-value=0.762). Considering that the scanning of other areas of the oral cavity in addition to the teeth is important in forensic odontology, the i500 scanner appears to be the most appropriate intraoral scanner for human identification. However, as the scope of oral scanning is generally limited to teeth in the practice of dentistry, additional discussions of how to apply the IOS in forensic odontology are needed. Ultimately, the results here can contribute to the overall discussion of the forensic applicability dental data produced by intraoral scanners.
