Objectives In pediatrics of Korean Medicine, it is crucial to evaluate the overall symptoms of children, especially in the children who have serious troubles in their life. In the era when diagnosis in Korean Medicine is quite suitable to evaluate multiple allergic diseases, and when growing numbers are in needs, development of an objective measurement scale for diagnosis of allergic disease in Korean Medicine became essential. Therefore, in the study, pediatric Allergic Disease Quality of Life Questionnaire (PADQLQ) was translated into Korean version with validations on some aspects. Methods In this study, we translated and validated the PADQLQ and established psychometric evidence on its utility in Korean children with similar problems. 71 children, age of 6 ~ 18 with allergic disease has participated. Results The internal consistency reliability of the PADQLQ by Cronbach's ${\alpha}$ was 0.94. In three domains (Practical, Physical, Emotional), the Cronbach's ${\alpha}$ was 0.77, 0.90 and 0.69. The Spearman's rank correlation coefficient between PADQLQ total score and VAS was 0.75 (p<0.001). And, Structural validity was evaluated by the ANOVA test. QoL differences of the four groups in the three domains (practical, physical, emotional) were significant. The item discriminative indices were ranged from 0.1651 to 0.8188. Conclusions Korean version PADQLQ is highly reliable and valid for children with allergic diseases. This is significant to assess the relative seriousness of the allergic diseases and to evaluate the efficacy of different treatments in Korean Medicine.

Purpose: The Perinatal Post-Traumatic Stress Disorder Questionnaire (PPQ) was designed to measure post-traumatic symptoms related to childbirth and symptoms during postnatal period. The purpose of this study was to develop a translated Korean version of the PPQ and to evaluate reliability and validity of the Korean PPQ. Methods: Participants were 196 mothers at one to 18 months after giving childbirth and data were collected through e-mails. The PPQ was translated into Korean using translation guideline from World Health Organization. For this study Cronbach's alpha and split-half reliability were used to evaluate the reliability of the PPQ. Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and known-group validity were conducted to examine construct validity. Correlations of the PPQ with Impact of Event Scale (IES), Beck Depression Inventory II (BDI-II), and Beck Anxiety Inventory (BAI) were used to test a criterion validity of the PPQ. Results: Cronbach's alpha and Spearman-Brown split-half correlation coefficient were 0.91 and 0.77, respectively. EFA identified a 3-factor solution including arousal, avoidance, and intrusion factors and CFA revealed the strongest support for the 3-factor model. The correlations of the PPQ with IES, BDI-II, and BAI were .99, .60, and .72, respectively, pointing to criterion validity of a high level. Conclusion: The Korean version PPQ is a useful tool for screening and assessing mothers' experiencing emotional distress related to child birth and during the postnatal period. The PPQ also reflects Post Traumatic Stress Disorder's diagnostic standards well.

Purpose: The aim of this study was to identify correlations between the STOP-Bang score and upper airway dimensions using cone-beam computed tomography (CBCT) scans. Materials and Methods: This study included 101 subjects (46 men, 55 women) from dental patients who received CBCT scans from 2014 to 2020. The patients were divided into those with a low obstructive sleep apnoea (OSA) risk (STOP-Bang score<3) and those with an intermediate to high OSA risk (STOP-Bang score≥3), and their upper airway dimensions were then analysed on CBCT scans. Comparisons between the low-risk and intermediate/high-risk groups were conducted using the t-test and the Mann-Whitney test. Correlations between the total STOP-Bang score and upper airway dimension parameters were established using Spearman correlation coefficients. P values≤0.05 were considered to indicate statistical significance. Results: Intermediate/high-risk subjects were predominantly male and over 50 years of age, with a higher body mass index. They had significantly longer upper airways, smaller average airway volumes, and smaller widths and antero-posterior dimensions of the narrowest upper airway segment. The total upper airway length was positively correlated with the STOP-Bang score (r_s=0.278). The average volume (r_s= -0.203) and width of the narrowest upper airway segment(r_s= -0.305) were both negatively correlated with STOP-Bang scores. Conclusion: Subjects with higher STOP-Bang scores had upper airways that were longer, narrower, and smaller in terms of average volume. CBCT scans taken for dental patients as part of investigative procedures could be correlated with STOP-Bang scores to screen for patients at risk of OSA.

Purpose: This study investigated Korean healthcare providers' attitudes toward sexual and gender minority (SGM) persons and their knowledge and behavior concerning the collection of data on sexual orientation and gender identity (SO/GI). Methods: In this cross-sectional, descriptive study, 137 Korean healthcare providers were recruited through convenience sampling from internet communities for medical professionals. A structured questionnaire was created using Google Surveys. The Mann-Whitney U-test, Kruskal-Wallis test, and Spearman correlation analysis were performed. Results: The sample was mostly women (80.3%) and nurses (83.9%), who had overall negative attitudes toward SGM persons and low levels of knowledge and behavior with regard to the collection of patients' SO/GI data. Participants in their 20s, who were religious, and had clinical experiences in treating or providing nursing care for SGM persons had higher levels of knowledge about the collection of SO/GI data. The level of engagement in collecting SO/GI data was higher among women and in their 20s and 30s, unreligious participants, nurses, and those with less than 10 years of clinical experience. Positive attitudes toward SGM persons were associated with higher levels of knowledge, but lower levels of behavior, regarding the collection of SO/GI data. Conclusion: It is important to recognize the diversity of patients' SO/GI and to collect the corresponding information. To this end, it is necessary to develop and use a standardized SO/GI form. Healthcare providers should also receive education and training related to the health of SGM persons to resolve health problems that disproportionately affect SGM persons and related health disparities.

The visually impaired who have many restrictions on their sight due to impairment of a sense of sight among special senses have substantial difficulties in the areas ranging from very minor behavior in their house to the external activities for social life. Visual impairment may cause many problems in various behaviors for protecting health which have recently drawn a lot of interests. As a method of analysis of collected data, this study conducted the frequency analysis of general characteristics and oral health behavior of the subjects, compared the average of oral public health behavior and oral health condition through t-test and F-test, and conducted the post verification of significant difference among groups with Duncan. For identifying the relevancy between the general characteristics and the oral health behavior, this study conducted Spearman's correlation analysis, and for identifying the impact on subjective, oral health condition, this study conducted multiple regression analysis. SPSS (SPSS20.0 for Windows, SPSS Inc, USA) was used as a statistical program, and the level of significance for determining statistical significance was considered at the level of 0.05. Because the visually impaired are the group whose behaviors for protecting health should be accurately recognized, this study intends to utilize the findings as basic materials for making information communication media suitable for the visually impaired by identifying the real conditions and behaviors of their oral health and analyzing their oral condition caused by such behaviors. With the help of information technology.

The field of wildlife habitat conservation research has attracted attention as integrated biodiversity management strategies. Considering the status of the species surveying data and the environmental variables in Korea, the GARP and Maxent models optimized for presence-only data could be one of the most suitable models in habitat modeling. For make sure applicability in the domestic environment we applied the machine learning species distribution model for analyzing habitats of the Korea water deer($Hydropotes$ $inermis$ $argyropus$) in the $Sapgyocheon$ watershed, $Chungcheong$ province. We used the $3^{rd}$ National Natural Environment Survey data and 10 environment variables by literature review for the modelling. Analysis results showed that habitats for the Korea water deer were predicted 16.3%(Maxent) and 27.1%(GARP), respectively. In terms of accuracy(training/test) the Maxent(0.85/0.69) was higher than the GARP(0.65/0.61), and the Spearman's rank correlation coefficient result of the Maxent(${\rho}$=0.71, p<0.01) was higher than the result of GARP(${\rho}$=0.55, p<0.05). However results could be depended on sites and target species, therefore selection of the appropriate model considering on the situation will be important to analyzing habitats.

Purpose To evaluate the ability of the Hounsfield unit (HU) measurement of the femoral neck during multidetector computed tomography (MDCT) for assessing osteoporosis compared with dual-energy X-ray absorptiometry (DXA). Materials and Methods Forty-two patients with femoral neck fractures who underwent MDCT and DXA from July to December 2016 were included in this study. HU measurements were made of the cancellous portions of the normal contralateral femoral neck on MDCT. Bone mineral density (BMD) and T-scores were obtained at the femur DXA. Correlations of HU values with BMD and T-scores were analyzed using Spearman's correlation test. Results The mean BMD and T-score of the femoral neck were 0.650 g/cm² and -2.4, respectively. The mean HU values for the normal, osteopenia, and osteoporosis groups were 131.9, 98.9, and 41.3, respectively. HU values at the femoral neck were positively correlated with BMD (r² = 0.670; p < 0.001) and T-scores (r² = 0.676; p < 0.001). Conclusion The HU values of the femoral neck on MDCT are significantly correlated with BMD and T-scores of femur DXA. The HU values may serve as a diagnostic tool for the screening of regional bone quality when MDCT is performed for other reasons.

Background: This study evaluated the validity and reliability of applying the Katz's Activities of Daily Living (ADL) scale in an Iranian sample of elderly oncologic patients following initial cancer treatment. Materials and Methods: The scale was translated with the forward-backward procedure to give an Iranian version. The ADL scale was then applied in a random sample of 400 oncologic patients aged 60 and older following initial cancer treatment. Assessment of the scale stability was twice, with a 14-days (two weeks) interval, to 30 (of the 400) eligible elderly cancer patients in March 2012. To measure treatment effects, the index was run with 150 patients in a three month recall, following oncology processing. Exploratory and confirmatory factor analysis was performed for assessment of construct validity of the Katz's ADL. Reliability was measured with internal consistency (Cronbach's alpha co-efficient), and test/retest (Spearman's r value) of the instrument. Criterion validity was evaluated by comparing the Katz with Physical Function (PF) subscale of SF 36. Known-group validity was approved by comparing of Katz' ADL between quartile groups of PF subscale of SF 36. Results: In our study the ADL demonstrated a high degree of internal homogeneity (Cronbach's alpha 0.923). There was a high correlation between scores of two time measurement of Katz's ADL (p value of two- related- samples test was 0.3). Construct validity showed a correlation coefficient of 0.572 between the ADL and PF scores. In factor analysis, 2 factors were extracted. Evidence for the reliability of the questionnaire was good and known group validity was approved by significant differences of ADL score between quartiles of the PF subscale of SF36. Conclusions: The results suggest that the Iranian version of ADL applied for oncologic older adult patients following initial cancer treatment is a reliable and a valid clinical instrument and comparable to those reported in other studies.

Purpose: The purpose of this study was to evaluate the machining precision and the marginal and internal fit of single restorations fabricated with three types of lithium disilicate ceramic blocks and to evaluate the correlation. Materials and methods: Single restorations were designed using a CAD software program. The crown designed model file was extracted from the CAD software program. Three types of lithium disilicate blocks (Rosetta; HASS, IPS e.max CAD; Ivoclar vivadent, VITA Suprinity; VITA) were milled using a milling machine. For the fabrication of the crown scanned model file, the intaglio surface of the restoration was digitized using a contact scanner. Then, using the three-dimensional inspection software (Geomagic control X; 3D Systems), the process of the overlap of the crown designed model and the scanned model and 3-dimensional analysis was conducted. In addition, the marginal and internal fit of the crowns was evaluated by a silicone replication method. The difference among three types of single ceramic crown was analyzed using a Kruskal-Wallis H test, and Spearman correlation analysis was performed to analyze the correlation between machining precision and fitness (α=.05). Results: There was a significant difference in the machining precision and the marginal and internal fit according to the type of ceramic block (P<.001). In addition, the machining precision and the marginal and internal fit were positively correlated (P<.001). Conclusion: The marginal fit of crowns fabricated according to the types of ceramic blocks was within the clinically acceptable range (< 120 ㎛), so it can be regarded as appropriate machining precision applicable to all clinical as aspects in terms of the marginal fit.

This study provides some basic information on the improvement of diabetics' self-care activities through examining the patients' knowledge on diabetes, self-care activities, and how much they feel those activities are effective and through studying the correlation among the three factors. One hundred and fifty four patients were subjected to this study, who were treated or hospitalized in a hospital in Pusan. Researches were conducted from October 21 to November 9, 2002, and information were gathered by questionnaire and direct conversation with the patients. The data was processed through SPSS WIN 10.0 program. The Date were analyzed by descriptive statistics, ANOVA, t-test, Pearson correlation coefficient and Spearman rank correlation coefficient. The results of this study was the followings; 1) The subjects' knowledge on diabetes ranged from 6 to 23 points with a mean of 17.01 points. 2) The subjects' self-care activities ranged from 21 to 103 points with a mean of 67.72 points. That of the patients with regular treatments appeared to have the highest points (3.51) and the lowest points appeared in the measurement of sugar level in blood (2.60) 3) The subjects' feelings of effectiveness ranged from 21 to 103 points with a mean of 70.01 points. Drug therapy had the highest point (3.94) and diet showed the lowest (3.37) 4) In the general characteristics of the subjects, the more education a subject had, the more knowledge on diabetes he or she appeared to have (F=3.36, p=0.012). The self-care activities were significantly high among non-alcoholic subjects (F=4.301. p=.016). The subjects' feelings of effectiveness were higher in female patients than in male patients(t=2.132 , p=.035), and those in the ages between 51 and 60 felt more effectiveness (F=4.198. p=.003). In addition, married subjects felt more effectiveness than the unmarried (t=2.856, p=0.005), and the more education a patient had. the more effectivess he or she felt (F=2.879, p=.025). 5) In the subjects' pathological characteristic, the subjects who experienced diabetes education showed more knowledge on diabetes, more self-care activity, and more effectiveness than those without the education (t=3.193, p=.002; t=2.299, p=.023; t=2.128, p=.035). 6) As the results of the analyses of correlations among knowledge on diabetes, self-care activity, and effectiveness, the more knowledge on diabetes a patient had, the more self-care activity and the more effectiveness he or she showed (p=0.283. p=0.002; p=0.182, p=0.036). Self-care activity became higher as the feeling of effectiveness appeared higher (r=.550, p=.000). Based on the results above, several suggestions were made; 1) This study was conducted in one hospital, so it is difficult to generalize the results. It is necessary to gather more information from more patients through repeated researches. 2) The study on the other factors which can affect a patient's self-care activity is required. 3) The development of a program which improves a patient's self-care activity, knowledge on diabetes. and effectiveness is needed.
