The observational method in tunnel engineering allows the evaluation in real time of the actual conditions of the ground and to take measures if its behavior deviates considerably from predictions. However, it lacks a consistent and structured methodology to use the monitoring data to adapt the support system in real time. The definition of limit criteria above which adaptation is required are not defined and complex inverse analysis procedures (Rechea et al. 2008, Levasseur et al. 2010, Zentar et al. 2001, Lecampion et al. 2002, Finno and Calvello 2005, Goh 1999, Cui and Pan 2012, Deng et al. 2010, Mathew and Lehane 2013, Sharifzadeh et al. 2012, 2013) may be needed to consistently analyze the problem. In this paper a methodology for the real time adaptation of the support systems during tunneling is presented. In a first step limit criteria for displacements and stresses are proposed. The methodology uses graphics that are constructed during the project stage based on parametric calculations to assist in the process and when these graphics are not available, since it is not possible to predict every possible scenario, inverse analysis calculations are carried out. The methodology is applied to the "Bois de Peu" tunnel which is composed by two tubes with over 500 m long. High uncertainty levels existed concerning the heterogeneity of the soil and consequently in the geomechanical design parameters. The methodology was applied in four sections and the results focus on two of them. It is shown that the methodology has potential to be applied in real cases contributing for a consistent approach of a real time adaptation of the support system and highlight the importance of the existence of good quality and specific monitoring data to improve the inverse analysis procedure.

건설공정관리는 주어진 공기 내에 공사를 완료하기 위해 투입되는 자원과 요소작업들의 종합적인 계획을 말한다. 이중 공사기간의 산정은 사업초기 신뢰할만한 근거에 의해 결정되어야 한다. 그러나 실제 현장에서는 담당자의 직관적 판단, 과거 유사 프로젝트의 공기 참고 등의 부정확한 방법으로 개별 작업기간이 결정되고 있다. 이러한 기존 방식의 개선을 위한 선행연구로 본 연구는 TBM공법 $({\phi}2.6m,\;{\phi}3.0m,\;{\phi}3.5m,\;{\phi}5.0m,\;{\phi}8.0m)$ 운영을 위한 건설사업의 초기단계에서 활용할 수 있는 표준모델을 제시하여 신속하게 전체 개략공기를 추정할 수 있는 공기를 산정하여 제시하였다. 따라서 본 연구에서 TBM 구경별로 분석하여 제시한 총 공사기간은 향후 TBM 공사를 수행할 때, 기본계획단계와 기본설계단계에서 공사계약, 공사비 산정, 공정계획을 수립하고 관리하는데 유용한 자료가 될 것으로 확신한다.

Stainless-clad (SC) bimetallic steels that are manufactured by metallurgically bonding stainless steels as cladding metal and conventional mild steels as substrate metal, are kind of advanced steel plate products. Such advanced composite steels are gaining increasingly widespread usage in a range of engineering structures and have great potential to be used extensively for large civil and building infrastructures. Unfortunately, research work on the SC bimetallic steels from material level to structural design level for the applications in structural engineering field is very limited. Therefore, the aim of this paper is to investigate the material behaviour of the SC bimetallic steels under the cyclic loading which structural steels usually could encounter in seismic scenario. A number of SC bimetallic steel coupon specimens are tested under monotonic and cyclic loadings. The experimental monotonic and cyclic stress-strain curves of the SC bimetallic steels are obtained and analysed. The effects of the clad ratio that is defined as the ratio of the thickness of cladding layer to the total thickness of SC bimetallic steel plate on the monotonic and cyclic behaviour of the SC bimetallic steels are studied. Based on the experimental observations, a cyclic constitutive model with combined hardening criterion is recommended for numerical simulation of the cyclic behaviour of the SC bimetallic steels. The parameters of the constitutive model for the SC bimetallic steels with various clad ratios are calibrated. The research outcome presented in this paper may provide essential reference for further seismic analysis of structures fabricated from the SC bimetallic steels.

Purpose: As health care needs for Lesbian, Gay, Bisexual and Transgender (LGBT) are becoming increasingly important, it has become imperative for the nurses to be attentive towards their health problems and provide nursing care with an open-minded attitude. Due to limited opportunity to provide direct nursing care to LGBT patients, it is hypothesized that simulation would provide good opportunity for students to experience LGBT nursing care in a safe environment. This study was conducted to develop and apply simulation of LGBT nursing care to ultimately provide unbiased nursing care for LGBT population and prepare basic data for LGBT nursing education. Methods: This study was a single-group pre-post experimental design study for 57 senior nursing students based on the comparison of existing LGBT knowledge, general attitude towards LGBT, and nursing attitude towards LGBT before and after simulation. The scenario content included discussion of coming out issue, providing sexual health information, and supportive nursing care for LGBT population. Data were analyzed with descriptive statistics and Wilcoxon signed rank. Results: Simulation education-led to a significant increase in LGBT knowledge and nursing attitude. However, there was no change in the general attitude towards LGBT. Conclusion: The results of this study suggest that LGBT education using simulation may be effective for nursing students and nurses from the point of concern for LGBT population. It is hypothesized that future LGBT educational programs might need more detailed information from both care recipients and nurses. Finally, LGBT education needs to be included in the nursing education curriculum.

The Korean traditional 'Ondol' system has been a target for innovation to meet the requirements of sustainable domestic building and low carbon emission energy utilization. Simulation techniques provide designers and researchers with powerful tools to predict heating load and thermal behaviour of Ondol systems installed in various contexts. However, there are few studies on Ondol models, especially associated with multi-stories buildings of which type covers about 50% of Korean housing stock. In this study, we analyzed the double floor Ondol system on the multi-stories buildings using the ESP-r program. On the basis of the double floor Ondol system, we suggested the new modelling method that is composed of the Vent zone and Ondol zone. Using the this model, sensitivity analysis was carried out to refine the applicability of the model taking account of control conditions, constructions, air change and air flow network method and CFD analysis using the FLUENT. The air layer has enough temperature to use in heating zone. It is suggested that the simplicity of the model will allow building designers and mechanical engineers easily to implement scenario-based assessments of design options as well as control strategies. Later, we will simulate the real buildings and analyze the air distributions using the Fluent according to the various conditions.
