This study investigated changes in the household expenditure for food outside home using the time-series family expenditure data during 1982-2002. Major findings were as following: first, expenditure for food outside home had been increasing, while over all level of the food expenditure had been decreasing; second, two thirds of the total amount of expenditure for food outside home were for regular meals; the proportion of food outside home which were paid to alcohols and other beverages have been decreasing since 1999; lastly, over the half of the total expenditure for food outside home had been spent on Korean food. Based on the results implications for consumer trends for food and food industry were provided.

PURPOSE: This study was performed to assess the reliability and validity of the Korean version of European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Chemotherapy-induced peripheral neuropathy 20 items (EORTC QLQ-CIPN20) in patients receiving neurotoxic chemotherapy. METHODS: A convenience sample of 249 Korean cancer patients, previously or currently, being treated with peripheral neurotoxic chemotherapeutic agents were asked to fill in the questionnaire. Collected data were analyzed using SPSS 21.0 and AMOS 21.0. Construct validity, known-group validity, concurrent validity, and internal consistency reliability of the Korean version of the QLQ-CIPN20 were evaluated. RESULTS: Factor analysis confirmed 3 dimensions of CIPN: sensory, motor, and autonomic. The factor loadings of the 20 items on the 3 subscales ranged from .38 to .85. The 3 subscale-model was validated by confirmatory factor analysis (GFI=.90, AGFI=.86, RMSR=.05, NFI=.87, and CFI=.94), and concurrent validity was demonstrated with the EORTC QLQ-C30. Furthermore, the QLQ-CIPN20 established known-group validity. The Cronbach's alpha coefficients for internal consistency of the subscales ranged from .73 to .89. CONCLUSION: The Korean version of the EORTC QLQ-CIPN20 showed satisfactory construct, concurrent, and known-group validity, as well as internal reliability.

PURPOSE: This study aimed to evaluate the clinical factors that could influence the length of hospital stay (LHS) of infants with acute bronchiolitis using the bronchiolitis severity score (BSS). METHODS: The medical records of 105 infants aged 0–12 months with acute bronchiolitis who were admitted to a tertiary hospital between December 2014 and May 2015 were reviewed. The BSS was composed 5 factors, namely general condition, wheezing, chest retraction, respiration rate, and peripheral oxygen saturation, which were evaluated at admission. In addition, the age of the infants, LHS, body weight, birth history, familial history, laboratory test result, chest X-ray, and treatment modalities were reviewed. Subjects were classified into 3 groups according to their BSS, and logistic regression analysis was used to identify the association of the BSS with longer LHS. RESULTS: Among subjects, 62 were studied. Their mean LHS and age were 5.5±2.0 days and 3.9±2.7 months, respectively. Twelve infants were classified as mild (20.3%), 43 as moderate (68.8%), and 7 as severe (10.9%). Venous blood gas pH value and white blood cell count were the best predictors of disease severity. The LHS was associated with the BSS, age, body weight and pCO2 by venous blood gas analysis (P<0.05). CONCLUSION: The LHS was associated with the BSS, age, body weight, and pCO₂ by venous blood gas analysis at admission. The BSS could be a useful tool to predict disease severity and decide treatment strategies for infants with acute bronchiolitis who have no known risk factors.

Pneumopericardium is a rare form of neonatal air leakage. Tension pneumopericardium is much more infrequent, but can cause a cardiovascular deterioration with high mortality up to 80% and neurodevelopmental morbidity in half of the cases. We report two cases of preterm infants who successfully recovered from tension pneumopericardium that developed during mechanical ventilator assistance. The patients displayed a sudden increase in oxygen demand and subsequent cardiovascular deterioration. Immediate needle aspiration of the pneumopericardium performed after checking X-ray images rescued each of patient. Since the clinical symptoms are non-specific, clinicians' suspicion is most important when patients show sudden refractory cardiovascular collapse, especially in ventilator-assisted neonates. This life threatening complication demands instant diagnosis and intervention.

PURPOSE: This clinical pilot study was performed to determine the effectiveness of dual-energy cone-beam computed tomography (DE-CBCT) in measuring bone mineral density (BMD).MATERIALS AND METHODS: The BMD values obtained using DE-CBCT were compared to those obtained using calibrated multislice computed tomography (MSCT). After BMD calibration with specially designed phantoms, both DE-CBCT and MSCT scanning were performed in 15 adult dental patients. Three-dimensional (3D) Digital Imaging and Communications in Medicine data were imported into a dental software program, and the defined regions of interest (ROIs) on the 3-dimensional surface-rendered images were identified. The automatically-measured BMD values of the ROIs (g/cm³), the differences in the measured BMD values of the matched ROIs obtained by DE-CBCT and MSCT 3D images, and the correlation between the BMD values obtained by the 2 devices were statistically analyzed.RESULTS: The mean BMD values of the ROIs for the 15 patients as assessed using DE-CBCT and MSCT were 1.09±0.07 g/cm³ and 1.13±0.08 g/cm³, respectively. The mean of the differences between the BMD values of the matched ROIs as assessed using DE-CBCT and calibrated MSCT images was 0.04±0.02 g/cm³. The Pearson correlation coefficient between the BMD values of DE-CBCT and MSCT images was 0.982 (r=0.982, P<0.001).CONCLUSION: The newly developed DE-CBCT technique could be used to measure jaw BMD in dentistry and may soon replace MSCT, which is expensive and requires special facilities.
