Purpose: This study aimed to evaluate the efficacy of simultaneous computed tomography (CT) and quantitative CT (QCT) in patients with osteoporotic hip fracture (OHF) by analyzing the osteoporosis detection rate and physician prescription rate in comparison with those of conventional dual-energy X-ray absorptiometry (DXA). Materials and Methods: This study included consecutive patients older than 65 years who underwent internal fixation or hip arthroplasty for OHF between February and May 2015. The patients were assigned to either the QCT (47 patients) or DXA group (51 patients). The patients in the QCT group underwent QCT with hip CT, whereas those in the DXA group underwent DXA after surgery, before discharge, or in the outpatient clinic. In both groups, the patients received osteoporosis medication according to their QCT or DXA results. The osteoporosis evaluation rate and prescription rate were determined at discharge, postoperative (PO) day 2, PO day 6, and PO week 12 during an outpatient clinic visit. Results: The osteoporosis evaluation rate at PO week 12 was 70.6% (36 of 51 patients) in the DXA group and 100% in the QCT group (P<0.01). The prescription rates of osteoporosis medication at discharge were 70.2% and 29.4% (P<0.001) and the cumulative prescription rates at PO week 12 were 87.2% and 60.8% (P=0.003) in the QCT and DXA groups, respectively. Conclusion: Simultaneous CT and QCT significantly increased the evaluation and prescription rates in patients with OHF and may enable appropriate and consistent prescription of osteoporosis medication, which may eventually lead to patients' medication compliance.

BACKGROUND/OBJECTIVES: This study aimed to evaluate how breastfeeding and complementary nutrition practices of mothers of 0-24-month-old children comply with the World Health Organization (WHO) recommendations for infant and young child feeding and to compare the results with selected demographic parameters related to the mother and child. SUBJECTS/METHODS: The research sample comprised mothers (n = 250) with children less than 2 years old. Data were obtained via questionnaire and were analyzed using SPSS 20.0 package program. The Pearson χ² or Fisher's exact tests were used for assessing relationships between categorical variables. The one-sample t-test was used for comparisons with reference values. RESULTS: Most mothers (97.2%) breastfed their babies immediately after birth. The mean time to breastfeeding after delivery was 47.8 ± 14.8 minutes, and 40.8% of the mothers complied with the WHO recommendation. Furthermore, 59.8% of the mothers exclusively breastfed their children for 6 months (mean 5.2 ± 1.5 months). The mean duration to the start of providing complementary food was 5.8 ± 0.6 months, and 76.1% of mothers who complied with the WHO recommendation. Only 12.3% of mothers breastfed their children for at least 12 months (mean 7.7 ± 3.3 months). On average, mothers gave cow milk to their children for the first time at 10.1 ± 1.7 months and honey at 11.8 ± 2.3 months. The mothers' rates of compliance with the WHO recommendations on cow milk and honey feeding were 32.0% and 71.6%, respectively. The rate of mothers who complied with the WHO minimum meal frequency recommendation was 88.3%. CONCLUSIONS: We suggest that the WHO recommendations on this subject will be realized more fully by emphasizing the importance of the positive effects of breastfeeding until the age of 2 years and of a timely start of complementary food provision. Such changes will affect child health over the long term.

This study attempted to demonstrate the interaction effects between attitudinal frames of nine daily newspapers and community structure in the 1994s Michigan gubernatorial election. It was theoretically guided by framing research and the self-presentation theory of social-cognition perspective and empirically tested with archival data. For the purpose of this study, content analysis of nine statewide daily newspapers was employed in order to provide data on news framing. Data on voting rates for John Engler, winner of the 1994 Michigan Gubernatorial election, in each county of Michigan were used for vote choice while Michigan census data were used for constructing an Index of community structural differentiation. The results indicated that majority compliance frames were slightly more related with vote choice in homogeneous com-unities rather than were majority compliance frames in heterogeneous communities while social identification frames tended to have an influence on vote choice in heterogeneous communities more than did social identification frames in homogeneous communities.

Purpose: In spite of the recent application of a general infection control method, central line-associated infections is still relatively high in Korea. Central line bundle with Chlorhexidine gluconate (CHG) tegaderm dressing was reported to be effective in reducing catheter colonization and central line-associated bloodstream infections (CLABSI). Therefore, this study aimed to examine the incidences of catheter colonization occurrence and CLABSI while using Tegaderm vs. CHG Tegaderm dressings. Methods: We used a descriptive design. 400 patients who had central venous catheters were selected from four hospitals in the Korean National Healthcare-associated Infections Surveillance System. Of all subjects, 200 used Tegaderm™ (Tegaderm group), and the remaining 200 used CHG Tegaderm (CHG Tegaderm group) dressing at the catheter insertion site. Data were analyzed using the χ² test or Fisher's exact test, t-test, and logistic regression analysis using SPSS WIN 21.0. Results: In the Tegaderm and CHG Tegaderm groups, CLABSI incidences were 5.89 and 1.79 per 1,000 catheter-days, catheter colonization incidences were 3.93 and 1.43 per 1,000 catheter-days, and central line bundle compliance rates were 26.0% and 49.0%, respectively. Catheter colonization risk factors were 'reinsertion after failure' and 'Tegaderm dressing' at the central line insertion site. CLABSI risk factors were 'incomplete performance of 7 central line bundle items' and 'Tegaderm dressing' at the central line insertion site. Conclusion: A further prospective study is needed to examine the effects of central line bundle with CHG Tegaderm dressing, avoiding central line reinsertion after failure, and improving the bundle compliance in reducing catheter colonization and CLABSI.

In order to apply the leak before break (LBB) concept to nuclear piping systems, the dynamic strain aging effect of low carbon steel materials has to be taken into account, in compliance with the requirements of the Korean Standard Review Guide (KSRG) 3.6.3-1. For this goal, J-R tests are needed for a range of various temperatures and loading rates, including dynamic loading conditions. In the dynamic loading J-R test, the unloading compliance method can not be applied to measure the crack growth and direct current potential drop (DCPD) method; this method also has a problem defining the crack initiation point. The normalization method is known as a very useful method to determine the J-R curve under dynamic loading because it does not need additional equipment or complicated loading sequences such as electric current or unloading. This method was accepted by the American Society for Testing and Materials (ASTM) as a standard test method E1820 A15 in 2001. However, it has not yet been clearly verified yet if the normalization method is sufficiently reliable to be applied to LBB. In this study, the basic background of the J-integral, LBB and dynamic loading J-R test are explained, and the current status for dynamic loading J-R test methods are reviewed from the view point of LBB for nuclear piping. In particular, the theoretical and historical background of the normalization method which has received attention recently, is summarized. Recent studies for this method are introduced and future works are suggested that may improve the reliability of LBB for nuclear piping.

Red pepper is one of the most important spices popularly utilized in Korea. Because of the differences in tariff rates between red pepper powder and seasoned red-pepper sauce, seasoned red-pepper sauce is often therefore imported by consumers, then dried, ground, and added to red pepper powder for cost effective purposed to use the product the most effectively. In this study, we combined species-specific polymerase chain reaction (PCR) assays (for red pepper, garlic, onion, spring onion, and ginger) with whole-genome amplification (WGA). Thirty-nine red pepper powders were well in accordance with their labels. However, six red pepper powder and five seasoned red-pepper sauce products failed to meet their compliance requirements. As a consequence, our monitoring results revealed that the overall mislabeling rate detected in this study was identified at 22%. Thus, our findings showed that the species-specific PCR in conjunction with WGA was an ideal method to identify raw materials that are used in the manufacturing of red pepper powder and seasoned red-pepper sauce.

Background: An inability to cope with threatening dental stimuli, i.e., sight, sound, and sensation of airotor, manifests as anxiety and behavioral management problems. Behavior modification techniques involving pre-exposure to dental equipment will give children a first-hand experience of their use, sounds, and clinical effects. The aim of this study was to compare the techniques of Tell-Show-Play-doh, a smartphone dentist game, and a conventional Tell-Show-Do method in the behavior modification of anxious children in the dental operatory. Methods: Sixty children in the age group of 4-8 years, with Frankl's behavior rating score of 2 or 3, requiring Class I and II cavity restorations were divided into three groups. The groups were Group 1: Tell-Show-Play-doh; Group 2: smartphone dentist game; and Group 3: Tell-Show-Do technique and each group comprised of 20 children. Pulse rate, Facial Image Scale (FIS), Frankl's behavior rating scale, and FLACC (Face, Leg, Activity, Cry, Consolability) behavior scales were used to quantify anxious behavior. Operator compliance was recorded through a validated questionnaire. Results: The results showed lower mean pulse rates, lower FIS and FLACC scores, higher percentage of children with Frankl's behavior rating score of 4, and better operator compliance in both the Tell-Show-Play-doh and smartphone dentist game groups than in the conventional Tell-Show-Do group. Conclusion: The Tell-Show-Play-doh and smartphone dentist game techniques are effective tools to reduce dental anxiety in pediatric patients.

Background and Purpose: Medication adherence is essential for effective medical treatment. However, it is challenging for cognitively impaired patients. We investigated whether an automated telephone reminder service improves medication adherence and reduces the decline of cognitive function in isolated patients with cognitive impairment. Methods: This was a single-center, randomized clinical trial. We enrolled mild cognitive impairment (MCI) or Alzheimer's disease (AD) patients who lived alone or with a cognitively impaired spouse. We provided an automated telephone reminder service for taking medication to the intervention group for 6 months. The control group was provided with general guidelines for taking the medication every month. The participants underwent neuropsychological assessment at the beginning and end of the study. Statistical significance was tested using nonparametric Wilcoxon rank sum and Wilcoxon matched-pairs signed-rank tests. Results: Thirty participants were allocated randomly to groups, and data for 29 participants were analyzed. The mean age was 79.6 (standard deviation, 6.0) years and 79.3% of the participants were female. There was no significant difference in medication adherence between the 2 groups. However, a subgroup analysis among participants with more than 70% response rates showed better medication adherence compared to the control group (intervention: 94.6%; control: 90.2%, p=0.0478). There was no significant difference in the change in cognitive function between the 2 groups. Conclusions: If a patient's compliance is good, telephone reminders might be effective in improving medication adherence. It is necessary to develop reminder tools that can improve compliance for cognitively impaired patients.

This study investigated the tax compliance applying framing effect, with the influence of detection rates, client advocacy, risk seeking tendency on the amount of income declared. Questionaires were filled in by CFA in Busan. Questionaires involve three cases (newly founded company, loss-expected company, gain-expected company). Respondents declared least in newly founded company, next loss-expected company, to gain-expected company. Respondents declared more as detection rates rose. As client advocacy increases, newly founded company and loss-expected company declare less, while gain-expected company declare more. As risk seeking tendency increases, newly founded company and loss-expected company declare less, but gain-expected company. Finally the interaction effect between client advocacy and risk seeking tendency is supported.

Purpose: Exercise intervention after surgery has been found to improve physical fitness and quality of life (QOL). The purpose of this study was to investigate the feasibility and effects of a postoperative recovery exercise program developed specifically for gastric cancer patients (PREP-GC) undergoing minimally invasive gastrectomy. Materials and Methods: Twenty-four patients treated surgically for early gastric cancer were enrolled in the PREP-GC. The exercise program comprised sessions of In-hospital Exercise (1 week), Home Exercise (1 week), and Fitness Improvement Exercise (8 weeks). Adherence and compliance to PREP-GC were evaluated. In addition, body composition, physical fitness, and QOL were assessed during the preoperative period, after the postoperative recovery (2 weeks after surgery), and upon completing the PREP-GC (10 weeks after surgery). Results: Of the 24 enrolled patients, 20 completed the study without any adverse events related to the PREP-GC. Adherence and compliance rates to the Fitness Improvement Exercise were 79.4% and 99.4%, respectively. Upon completing the PREP-GC, patients also exhibited restored cardiopulmonary function and muscular strength, with improved muscular endurance and flexibility (P<0.05). Compared to those in the preoperative period, no differences were found in symptom scale scores measured using the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30) and Quality of Life Questionnaire-Stomach Cancer-Specific Module (QLQ-STO22); however, higher scores for global health status and emotional functioning were observed after completing the PREP-GC (P<0.05). Conclusions: In gastric cancer patients undergoing minimally invasive gastrectomy, PREP-GC was found to be feasible and safe, with high adherence and compliance. Although randomized studies evaluating the benefits of exercise intervention during postoperative recovery are needed, surgeons should encourage patients to participate in systematic exercise intervention programs in the early postoperative period (Registered at the ClinicalTrials.gov, NCT01751880).
