Purpose: This follow up study was performed to survey the problem in performing ADLs at home after surgery. Method: Twenty elderly patients were assessed 3 times; from the time of hospitalization for surgery until 3 weeks after discharge. Measuring tools are numeric rating scales (NRS) for pain and 3 questionnaires developed by the authors to measure difficulties in ambulation, performing indoor ADLs, and emotional status. Pearson correlation, variance analysis and descriptive statistics were used to analyze the data. Result: The level of pain significantly decreased after surgery, but the difference between pain at the time of discharge and that of 3 weeks after discharge were not significant. Pain showed a positive relationship with emotional difficulties. Elderly with a higher education, family caregiver, and regular exercise showed a lower level of emotional difficulties. Conclusion: Comprehensive approaches for chronic pain including physical, psychological, and social aspects should be considered when caring for the elderly with spinal surgery. In addition, home care nursing interventions should include an exercise program to promote adaptation and rehabilitation after discharge.

This study discusses a contract to promote collection and recycling of used products in a green supply chain (GSC). A collection incentive contract is combined with a reward-penalty contract. The collection incentive contract for used products is made between a retailer and a manufacturer. The reward-penalty contract for recycling used products is made between a manufacturer and an external institution. A retailer pays an incentive for collecting used products from customers and delivers them to a manufacturer with a product order quantity under uncertainty in product demand. A manufacturer remanufactures products using recyclable parts with acceptable quality levels and covers a part of the retailer's incentive from the recycled parts by sharing the reward from an external institution. Product demand information is assumed as (i) the distribution is known (ii) mean and variance are known. Besides, the optimal decisions for product quantity, collection incentive of used products and lower limit of quality level for recyclable parts under decentralized integrated GSCs. The analysis numerically investigates how (1) contract for recycling activity, (ii) product demand information and (iii) quality of recyclable parts affect the optimal operation for each GSC. Supply chain coordination to shift IGSC is discussed by adopting Nash Bargaining solution.

Purpose : This study examined factors influencing the attitudes towards nurse-led defibrillation in the emergency department (ED) and intensive care unit (ICU). Methods : This was a cross-sectional study. A total of 212 nurses in the ED and ICU from three general hospitals responded to the survey. Data were collected between September and October 2015 using structured questionnaires. Independent t-test, Mann-Whitney U test, one-way analysis of variance (ANOVA), Pearson's correlation coefficient, and hierarchical multiple regression were used to analyze factors affecting nurses' attitudes towards nurse-led defibrillation. Results : The mean score of nurses' attitudes towards nurse-led defibrillation was 61.37 of a possible 91. Hierarchical multiple regression showed that nurses' attitudes towards nurse-led defibrillation were significantly affected by their experiences regarding cardiopulmonary resuscitation (p=.003), knowledge regarding electrocardiogram interpretation and defibrillation (p=.007), and tenure in ED or ICU (p=.043). Conclusion : Results indicate that employers should set policies to support nurses in maintaining their careers in the ED or ICU and conduct systematic educational programs for them. This will increase nurses' confidence in performing defibrillation, which will lead to early defibrillation during in-hospital cardiac arrest. Consequently, it can be a strategy to increase the survival rate of cardiac arrest patients.

Large Eddy Simulation(LES) of turbulent mass transfer in fully developed turbulent pipe flow has been performed to study the effect of Reynolds number on the concentration fields at $Re_{\tau}=180$, 395, 590 based on friction velocity and pipe radius. Dynamic subgrid-scale models for the turbulent subgrid-scale stresses and mass fluxes were employed to close the governing equations. Fully developed turbulent pipe flows with constant mass flux imposed at the wall are studied for Sc=0.71. The mean concentration profiles and turbulent intensities obtained from the present LES are in good agreement with the previous numerical and experimental results currently available. The effects of Reynolds number on the turbulent mass transfer are identified in the higher-order statistics(Skewness and Flatness factor) and instantaneous concentration fields. The budgets of turbulent mass fluxes and concentration variance were computed and analyzed to elucidate the effect of Reynolds number on turbulent mass transfer. Furthermore, to understand the correlation between near-wall turbulence structure and concentration fluctuation, we present an octant analysis in the vicinity of the pipe wall.

This study explores the attributes of the on-line shopping products and prices, and their effects on the customer satisfaction. In doing so, the sample population has been segmented according to their shopping propensity of consumption on clothing to understand the group differences. Based on the previous researches, the researcher have chosen four important characteristics of the customer's shopping propensity. The number of iteration on factor analysis revealed that the sample population can be classified into three different groups; the convenience/pleasure-seeking group, the fashion/utility-seeking group, and the unconcerned group. The significant group differences resulted on the following study variables; the product assortment, the price rationality, and the value of the price. Also, from the product aspect, the characteristic, the assortment, and the expression in order, explained the significant portion of the Y variance. While, on the aspect of price, the rationality, and information in order, significantly contributed on the customer satisfaction.

Purpose: This study was performed to examine the frequency of irritable bowel syndrome(IBS), perceived stress, and mental health among community-dwelling women. Methods: This study conducted a survey to collect data on 869 women in Seoul and Gyeonggi-do. The measurements included the Rome III criteria(to diagnose IBS), the Global Assessment Recent Stress(GARS scale to evaluate perceived stress), and symptom check list 90R(SCL-90R to evaluate psychological distress). Data were analyzed using SPSS 15.0 program by frequency, $x^2$-tests, t-test, and analysis of variance(ANOVA). Results: The frequency of IBS in women was 15.1%. Eighty-six women(65.6%) had mixed constipation and diarrhea subtype of IBS. Compared to the women without IBS, those with IBS reported significantly higher scores on GARS, all subscales of GARS, SCL-90R, all subscales of SCL-90R, and the global severity index(GSI). No significant differences were observed among stress, mental health, and the IBS subtypes. Conclusion: Nursing interventions targeting women with IBS should be developed in order to reduce the associated stress and psychological distress.

Effects on feed intake, liveweight gain and economic benefits of supplementing lambs with urea molasses blocks, were studied. Forty eight crossbred lambs were divided into 6 groups and assigned randomly to grazing on native pasture (CONT) or along with supplements of Commercial ration (COM) and urea molasses blocks (UMBs) containing two levels of cement and calcium oxide as a binding agent. Analysis of variance revealed highly significant (p<0.01) differences in dry matter (DMI, g/day), crude protein (CPI, g/day) and metabolizable energy (MEI, MJ/day) intakes. Differences in liveweight gain (LWG, g/day), feed conversion ratio (FCR) and net economic benefit of supplementation were also highly variable. The intake of DM, CP and ME varied from 974 to 1002, 66-70 and 7.6-8.4 in lambs supplemented with UMBs, significantly (p<0.01) greater than 848, 52.5 and 5.6 in lambs supplemented with COM or FCR and net economic benefits (54.3; 57.8; 17.1 and 1.96; 2.4) in lambs supplemented with COM and UMB-2, were CONT or supplemented with UMB-1, UMB-3 and UMB-4 respectively. Factors responsible for differences in feed intake, liveweight gain and economic benefits, are discussed.

Purpose: The purpose of this study was to identify the influencing factor to self actualization in middle-aged women. Method: The subjects for this study were 191 middle-aged women selected by convenience sampling in three cities. Data collection was done using a questionnaire. The data were analyzed by using descriptive statistics, Pearson Product Moment Correlation coefficient and Stepwise Multiple Regression. Result: The results of this study were as follows: 1. The relationship between self-efficacy, social support, self esteem, motivation for achievement, parental satisfaction with children and self-actualization were found to have statistically significant positive correlations. But the relationship between depression and self-actualization were found to have statistically significant negative correlation. 2. Stepwise multiple regression analysis revealed that the most powerful predictor was social support. Social support, motivation for achievement and self esteem accounted for 38.1% of the variance in self-actualization in middle aged women. Conclusion: According to these results, it is recommended that in order to enhance self-actualization in middle-aged women, empowerment of social support, motivation for achievement and self esteem should be pursued.

This study aimed to develop a design manual to be used during the initial stage of the nearly Zero Energy Building (nZEB) design process. Recently, with the increased demand for nZEBs, there are many architects and architectural firms who are becoming interested in nZEB design. However, since the nZEB design process requires a different approach to the conventional building design process, architects have difficulties with application of the nZEB design process in their projects. Therefore, a design manual which can be used in the nZEB design process was developed in this study. Based on an intensive literature review, energy-saving strategies and their performance levels, which affect heating and cooling energy consumptions were established for a reference building. To analyze the sensitivity of each energy strategy to the overall performance, computer simulations using EnergyPlus were performed. At the same time, an Analysis of Variance assessment was conducted to estimate the relative importance of each energy factor. The energy sensitivity and priority of the energy factors was developed into a set of design guidelines.

We investigated the genetic structure of Korean and Japanese ayu Plecoglossus altivelis populations by examining 669 individuals from 14 populations using three microsatellite loci. Genetic variation did not differ significantly among the populations examined in terms of allelic number and heterozygosity. Korean populations were genetically close to each other, implying that persistent gene flow has occurred in these populations. This suggests that eastern populations in Korea form a single large population and all of the Korean populations are distinct from the Japanese populations. Pairwise population $F_{ST}$ estimates, principal component analyses, and a neighbor-joining tree showed that genetic separation between the southern and pooled eastern coast populations was probably influenced by restricted gene flow. Hierarchical analysis of molecular variance (AMOVA) revealed a weak but significant genetic structure among three ayu groups (eastern and southern coasts of Korea and the Japan coast), and no genetic variation within groups. The estimated genetic population structure and potential applications of microsatellite markers may aid in the proper management of ayu populations.
