Purpose: In this study a system dynamics methodology was used to identify correlation and nonlinear feedback structure among factors affecting unplanned extubation (UE) of ICU patients and to construct and verify a simulation model. Methods: Factors affecting UE were identified through a theoretical background established by reviewing literature and preceding studies and referencing various statistical data. Related variables were decided through verification of content validity by an expert group. A causal loop diagram (CLD) was made based on the variables. Stock & Flow modeling using Vensim PLE Plus Version 6.0b was performed to establish a model for UE. Results: Based on the literature review and expert verification, 18 variables associated with UE were identified and CLD was prepared. From the prepared CLD, a model was developed by converting to the Stock & Flow Diagram. Results of the simulation showed that patient stress, patient in an agitated state, restraint application, patient movability, and individual intensive nursing were variables giving the greatest effect to UE probability. To verify agreement of the UE model with real situations, simulation with 5 cases was performed. Equation check and sensitivity analysis on TIME STEP were executed to validate model integrity. Conclusion: Results show that identification of a proper model enables prediction of UE probability. This prediction allows for adjustment of related factors, and provides basic data do develop nursing interventions to decrease UE.

Purpose: The purpose of this study was to review interventions available to nurses caring for siblings of children with cancer. Methods: Searches of CINAHL, MEDLINE, PubMed, EMBASE, and RISS identified ten intervention studies published from January, 2000 to November, 2016. Results: Ten studies on interventions for siblings of pediatric cancer patients were identified as follows: 4 included camps, 4 included support groups, and 2 provided individual interventions. Theoretical frameworks were mainly cognitive behavioral theory and most studies were led by psychologists and multidisciplinary teams. The purpose of the interventions was primarily enhancing psychosocial adjustment. Siblings' fear of disease, self-esteem, and social support were improved significantly after the interventions. Findings were inconsistent with regard to depression, anxiety, behavioral problems, post-traumatic stress, health-related quality of life, and siblings' perceptions of the illness. Conclusion: Study findings showed the potential for enhancing emotional and behavioral outcomes in siblings of children with cancer. However, the number of studies was very small, and several methodological limitations were identified. In the future, more randomized controlled trials with larger samples are needed to extend the evidence base. Moreover, future research should identify sibling's characteristics and circumstances most likely to bring benefits to the siblings.

The purpose of this study was to suggest menu pricing strategy based on understanding about customer perceived value of products and services. The technique known as PSM (Price Sensitivity Measurement) was used for analysis of price sensitivity for 3 menu items of a family restaurant in Seoul. A questionnaire was developed through literature review and modified after pilot test. Questionnaires for the main survey were distributed to 250 customers on their visit to the restaurant, and a total of 138 questionnaires were used for analysis (55.2%). The statistical analysis of price sensitivity was conducted using PSM, and descriptive analyses were conducted using SPSS Win (12.0). The main results of this study were as follows: the price sensitivity of beef tenderloin steak was higher than two other menus and the stress range of teriyaki chicken was almost 0, that is, the price sensitivity of teriyaki chicken was very low. Present menu prices of 3 menu items were within the range of acceptable prices, but had some distances from the optimal pricing point. From the result of this study, it was concluded that price adjustment or price promotion strategy would be effective for increase in sales of beef tenderloin steak, and marketing strategies to enhance consumers' perceptions of value should be conducted for all menu items by situations. Overall, PSM technique could be a helpful tool for researchers and managers of foodservice organizations to understand how consumers' perceptions of value are affected by the interaction of price and quality.

Objectives: This study aimed to assess the association between physical activity and health-related quality of life (HRQOL) in Koreans. Methods: A total of 9,689 adults(${\geq}19$ years, 4,036 men) from the Fourth National Health and Nutrition Examination Survey(2007-2008) were examined by the International Physical Activity Questionnaraire (IPAQ)-short form and Korean EuroQol-5 Dimension(KEQ-5D). Results: For the physical activity by IPAQ, 'Inactive group' was 75.3%, 'Minimally active group' was 23.5%, and 'Health-Enhancing Physical Activity(HEPA) group' was 1.2%. The mean HRQOL index was $0.89{\pm}0.13$. These relations of physical activity and HRQOL remained significant after adjustment for age, sex, smoking, subjective health status, stress, depression, and socioeconomic status variables (Adjusted $R^2$ = 0.334). Conclusions: Physical activity was associated with health-related quality of life. Physically active group had higher health-related quality of life than the inactive group.

In the water-filling and preloading test, the sensing cables were installed on the surface of steel spiral case and in the surrounding concrete to monitor the strain distribution of several cross-sections by using Brillouin Optical Time Domain Analysis (BOTDA), a kind of distributed optical fiber sensing (DOFS) technology. The average hoop strain of the spiral case was about $330{\mu}{\varepsilon}$ and $590{\mu}{\varepsilon}$ when the water-filling pressure in the spiral case was 2.6 MPa and 4.1 MPa. The difference between the measured and the calculated strain was only about $50{\mu}{\varepsilon}$. It was the first time that the stress adjustment of the spiral case was monitored by the sensing cable when the pressure was increased to 1 MPa and the residual strain of $20{\mu}{\varepsilon}$ was obtained after preloading. Meanwhile, the shrinkage of $70{\sim}100{\mu}{\varepsilon}$ of the surrounding concrete was effectively monitored during the depressurization. It is estimated that the width of the gap between the steel spiral case and the surrounding concrete was 0.51 ~ 0.75 mm. BOTDA based distributed optical fiber sensing technology can obtain continuous strain of the structure and it is more reliable than traditional point sensor. The strain distribution obtained by BOTDA provides strong support for the design and optimization of the spiral case structure.

본 연구에서는 국내 지반굴착에 의한 지반거동 수치해석 평가 시 주로 사용되고 있는 Mohr-Coulomb 모델의 한계점을 분석하고, 실제 지반굴착 거동에 잘 부합되는 Hyperbolic 모델과 수치해석 결과를 비교하였다. 최근 국내에서 Mohr-Coulomb 모델 사용 시 지반굴착면이 실제보다 과다하게 융기되는 현상을 제어하기 위해서 특별한 경계조건을 임의대로 부과해서 해결하는 경향이 있다. 이러한 결과는 굴착면의 융기량의 크기만 제어할 뿐 지반거동이 실제와 왜곡되어 나타나는 문제점을 내포하고 있다. 본 연구에서 Hyperbolic 모델(Hardening Soil model)을 사용한 결과와 Mohr-Coulomb 모델을 사용한 결과를 비교하여, Hyperbolic 모델이 굴착 지반 융기량 및 실제 지반의 응력-변형거동에 더 잘 부합됨을 확인하였다. 지반굴착에 관한 수치해석 분석 시 Hyperbolic 모델을 사용하는 것이 실제 지반거동에 부합되는 결과를 얻을 수 있을 것으로 판단된다.
