Considering the importance of institutional foodservice in modern dietary life and its influence on the environment, sustainable development in institutional foodservice industry carries great significance. The current study was conducted to investigate dietitians' perceptions of sustainable business-and-industry foodservice and their intentions to perform sustainable practices by applying a mixed methodology. For the quantitative study, an online survey was conducted on 362 dietitians who had worked at a contact foodservice company for more than 1 year. The survey was performed from December 15th, 2011 to January 30th, 2012, and 202 responses were used for the analysis. For the qualitative a study, a focus group interview was conducted during May, 2012 with representative employees of the company. According to the results, dietitians seemed to be unfamiliar with the terms "sustainability" or "sustainable development," whereas they understood related contents and practices. Dietitians' awareness and perceived need in terms of sustainable business-and-industry foodservice were not significantly different across general characteristics. Dietitians seemed to be highly aware of the impacts of business-and-industry foodservice on economy, whereas they appeared to lack understanding of its impacts on society and environment. Cost increase and levy on work in daily operations were considered as main obstacles hampering dietitians' intentions to perform sustainable practices. A total of 88.1% of responding dietitians expected that the meal price at a sustainable business-and-industry foodservice should be higher than the supposed standard price of 4,000 won, with an average reaching 5,270 won. Findings from this study could be used as baseline information for vitalizing sustainable business-and-industry foodservice in Korea.

The purpose of this study was to examine the effect of sustainability management (SM) at coffee houses on customers' store image and behavioral intention. In addition, customers' willingness to pay a premium for sustainable coffee houses was studied. During October 2011, a web survey was conducted via an on-line research company with customers aged 20 to 39 visiting one of the top five coffee houses in Korea at least once a month. A total of 300 targeted customers responded and all the data were analyzed. An exploratory factor analysis derived two dimensions of SM: SM in Social and Environmental Perspective and SM in Economic Perspective. The result of structural equation modeling indicated that SM in Economic Perspective at coffee houses had a significant positive effect on customers' behavioral intention with mediating effect by store image, but SM in Social and Environmental Perspective did not have such effect. Approximately one-third (31%) of the respondents were willing to pay a premium for a sustainable coffee house in a scenario. approximately 84% of the respondents unwilling to pay a premium for the sustainable coffee house chose the cost-related reasons including "Coffee price at the coffee house that they most often visit is already expensive (62.3%)" for such unwillingness. The results of this study showed that SM of coffee houses, especially that in Economic Perspective, could contribute to store image, and therefore increase customers' favorable behavioral intention, although the additional cost resulted from such SM practices might not be easily accommodated by customers.

Purpose: This study aimed to assess combined effects of early oral feeding after Cesarean section (C/S) under regional anesthesia on bowel function, gastrointestinal complications and surgical recovery. Methods: A systematic literature search was conducted using KISS, RISS, PubMed, CINAHL, EMBASE, CENTRAL and Google Scholar to identify randomized clinical trials comparing early oral feeding (EOF) with delayed oral feeding (DOF) after C/S. Outcome variables were bowel function and gastrointestinal complications and surgical recovery. Effect size was calculated using weighted mean differences (WMDs) and relative risks (RRs), with 95% confidence intervals (CIs). Results: Seven studies involving 1,911 patients from 568 studies, 7 studies were included in meta-analysis. EOF was significantly associated with shorter time to recover bowel movement compared with DOF (WMD, - 2.50; CI, - 3.50~- 1.50). EOF was not associated with nausea (RR, 1.15; CI, 0.87~1.53) and vomiting (RR, 0.96; CI, 0.65~1.42), but lower incidence of abdominal distension (RR, 0.70; CI, 0.50~0.98). EOF was significantly associated with shorter time to discontinuation of intravenous fluids (WMD, - 8.88; 95% CI, - 16.65~- 1.11) and removal of urinary catheter (WMD, - 15.23; CI, - 25.62~- 4.85). Conclusion This meta-analysis provides evidence that EOF after C/S under regional anesthesia not only accelerates return of bowel function and surgical recovery but also reduces gastrointestinal complications. These results suggest that EOF should be offered to women who have undergone C/S to improve the recovery experience and reduce overall medical costs.

This study aimed to evaluate the effectiveness of the foodservice management support program focusing on menu management in community child centers. The support program provided reference menus, staff training, and field consulting to 10 community child centers in the Jeollanam-do province for one month, August in 2010. One month menus were developed, based on children's preference for menu items, foodservice personnel's preference for food materials, and availability of local specialty foods, and offered as reference menus. In addition, staff training and field consulting focusing on menu management were conducted before and during the pilot period, respectively. To evaluate the support program, menus, foodservice personnel's knowledge level and perceived performance in foodservice management, and children's level of satisfaction for foodservice were analyzed before and after the support program. As a result of analysis of 222 and 210 menus of before and after the support program, respectively, the number of dishes per meal increased from five to six on average, and the proportion of meals including five food groups, which were grain, meat, vegetable, fruit, and milk and dairy product, rose from 2% to 24%. Foodservice personnel's knowledge level regarding foodservice management increased significantly (p = 0.007), however, their perceived performance in foodservice management did not show any significant changes. Children were more satisfied with 'food' (p = 0.001), 'sanitation' (p = 0.001), and 'environment' (p < 0.008) of foodservice in community child centers after the support program. In conclusion, the foodservice management support program focusing on menu management in this study was effective for improving menu quality of and children's satisfaction with foodservice in community child centers.

PURPOSE: Mortality rate in the health services research field is frequently considered as a proxy for measuring healthcare quality. We compared the mortality rate and hospitalization levels among patients with poisoning. METHODS: A population-based study of hospital size and level based on the Korean health insurance and assessment service was conducted to identify the impact of hospital level on patient mortality. RESULTS: We analyzed a total of 16,416 patients, of which 7,607 were from tertiary hospitals, 8,490 were from general hospitals, and 319 were from hospitals. The highest mortality rate of diagnosis regarding poisoning was T60.31 (other herbicides and fungicides, 16%), followed by T60.0 (organophosphate and carbamate insecticides, 12.7%). There was no statistical difference in mortality among hospital levels for gender. Among age groups, tertiary hospitals had lower mortality than general hospitals and hospitals for patients aged more than 70 years (11.9% mortality at tertiary vs 14.2% at general and 23% at hospital; p=0.003, adjusted z score=−6.9), general hospitals had lower mortality than tertiary hospitals and hospitals for patients aged 18 to 29 (0.6% at general vs 2.4% at tertiary and 3.7% at hospital; p=0.01, adjusted z score=−4.3), and hospitals had lower mortality than tertiary hospitals and general hospitals for patients between 50 and 59 years of age (0% at hospital vs 6.4% at general and 8.3% at tertiary; p=0.004). CONCLUSION: Overall, there was no significant difference between mortality and hospital level among poisoned patients. However, to establish an efficient treatment system for patients with poisoning, further studies will be needed to identify the role of each facility according to hospital level.

Unenhanced echocardiography (UE), commonly used in veterinary practice, is limited by left ventricular (LV) foreshortening and observer dependency. Contrast echocardiography (CE) was used to compare two-dimensional (2D) LV measurements made using UE and 256-row multi-detector computed tomography (MDCT) as a reference standard. Seven healthy beagle dogs were evaluated in this study. Measurements obtained using CE, including LV wall thickness, internal diameter, and longitudinal and transverse length, were significantly greater than those obtained using UE. Measurements of LV internal dimension in diastole (LVIDd) and systole (LVIDs) were significantly larger with CE compared UE. Regardless of the cardiac cycle, LV longitudinal (LVLd and LVLs) and transverse diameter (LVTDd and LVTDs) measurements were significantly different with CE and approximated values from MDCT. Among automatically calculated parameters, LV end-systolic volume and the relative wall thickness were significantly different between UE and CE. In CE, the correlation coefficients of 4 major parameters (r = 0.87 in LVIDd; 0.91 in LVIDs; 0.87 in LVLd; and 0.81 in LVLs) showed higher values compared to the UE (r = 0.68 in LVIDd, 0.71 in LVIDs, 0.69 in LVLd, and 0.35 in LVLs). Inter-observer agreement was highest for MDCT and higher for CE than UE. In conclusion, CE is more accurate and reproducible than UE in assessing 2D LV measurements and can overcome the limitations of UE including LV foreshortening and high observer dependency.

Background: Carvedilol is a beta-adrenergic receptor antagonist primarily metabolized by cytochromes P450 (CYP) 2D6. This study established a carvedilol population pharmacokinetic (PK)–pharmacodynamic (PD) model to describe the effects of CYP2D6 genetic polymorphisms on the inter-individual variability of PK and PD. Methods: The PK–PD model was developed from a clinical study conducted on 21 healthy subjects divided into three CYP2D6 phenotype groups, with six subjects in the extensive metabolizer (EM, *1/*1, *1/*2), seven in the intermediate metabolizer-1 (IM-1, *1/*10, *2/*10), and eight in the intermediate metabolizer-2 (IM-2, *10/*10) groups. The PK–PD model was sequentially developed, and the isoproterenol-induced heart rate changes were used to establish the PD model. A direct effect response and inhibitory E max model were used to develop a carvedilol PK–PD model. Results: The carvedilol PK was well described by a two-compartment model with zeroorder absorption, lag time, and first-order elimination. The carvedilol clearance in the CYP2D6*10/*10 group decreased by 32.8% compared with the other groups. The inhibitory concentration of carvedilol estimated from the final PK–PD model was 16.5 ng/mL regardless of the CYP2D6 phenotype. Conclusion The PK–PD model revealed that the CYP2D6 genetic polymorphisms were contributed to the inter-individual variability of carvedilol PK, but not PD.

OBJECTIVES: The aim of this study was to investigate whether a medium to high degree of total physical activity and indoor physical activity were associated with reduced all-cause and cardiovascular mortality among elderly Korean women. METHODS: A prospective cohort study was done to evaluate the association between physical activity and mortality. The cohort was made up of elderly (> or =65 years of age) subjects. Baseline information was collected with a self-administered questionnaire and linked to death certificates retrieved from a database. Cox proportional hazard models were used to estimate the hazard ratios (HRs) with 95% confidence interval (CI) levels. RESULTS: Women who did not suffer from stroke, cancer, or ischemic heart disease were followed for a median of 8 years (n=5079). A total of 1798 all-cause deaths were recorded, of which 607 (33.8%) were due to cardiovascular disease. The group with the highest level of total physical activity and indoor physical activity was significantly associated to a reduced all-cause mortality (HR, 0.60; 95% CI, 0.51 to 0.71 and HR, 0.58; 95% CI, 0.50 to 0.67, respectively) compared to the group with the lowest level of total physical activity and indoor physical activity. Additionally, the group with the highest level of total physical activity and indoor physical activity was significantly associated to a lower cardiovascular disease mortality (HR, 0.53; 95% CI, 0.40 to 0.71 and HR, 0.51; 95% CI, 0.39 to 0.67, respectively) compared to the group with the lowest level of total physical activity and indoor physical activity. CONCLUSIONS: Our study showed that regular indoor physical activity among elderly Korean women has healthy benefits.

BACKGROUND: Accurate typing of Duffy blood group is important because anti-Duffy antibodies cause hemolytic transfusion reaction and hemolytic disease of the newborn. The aim of this study was to evaluate a new genotyping method using high resolution melting (HRM) analysis, a rapid and inexpensive approach for high-throughput Duffy genotyping. METHODS: A total of 20 unrelated Korean blood samples were obtained and an African-black sample was used for GATA control. Phenotyping was performed by hemagglutination (DiaMed AG, Switzerland). GATA and FYA/B PCR products were obtained by PCR-restriction fragment length polymorphism (RFLP) using Taq DNA polymerase (Promega, WI) and enzymes BanI and StyI (New England Biolab, UK). For HRM, PCR amplification was performed using LightCycler 480 ResoLight Dye (Roche, USA) and Lightcycer 480 (Roche, USA). RESULTS: Phenotyping and genotyping data using PCR-RFLP and HRM analysis were compared. Different types of HRM curves were obtained according to genotypes, FYA/FYA, FYB/FYB, and FYA/FYB, and to GATA mutations, homozygote FYB-33T (T/T), heterozygote FYB-33T/33C (T/C), and homozygote FYB-33C (C/C). Phenotypes 18 Fy(a+b-), 1 Fy(a+b+), 1 Fy(a-b+), and 1 Fy(a-b-) showed complete concordance with genotyping methods. Fy(a-b-) sample was found to be a FYB-33C homozygote by both genotyping methods. CONCLUSION: Phenotyping and genotyping showed concordant results and both genotyping methods using PCR-RFLP and HRM analysis showed good agreement in finding mutation in GATA and FY gene coding regions. HRM analysis is suitable and reliable for high-throughput screening for Duffy genotyping.
