This study aimed to develop simulation practice program with PBL (S-PBL) for nursing students and evaluate the effect of the program on their problem solving ability, clinical performance competency, learning satisfaction and confidence. The participants were nursing students who applied for simulation practice courses at an university in J province. The study was a mixed-method design using a nonequivalent one group pretest-posttest design (n=91) and focus group interview (n=12). Quantitative data were analyzed using SPSS 23.0 program and qualitative data thematic analysis. Quantitative data showed S-PBL was effective in improving clinical performance competency, learning satisfaction and confidence of the participants, but not in improving problem solving ability. As a result of the qualitative study, four themes and eight sub-themes were derived, and the themes were "Learn integrated nursing care based on priority", "Experience team cooperation through communication," "Learn vividly critical care" and "Improved nursing competency". The S-PBL could be effective in practical education for nursing students. In further study, it is necessary to develop various simulation practice programs based on PBL through a mixed-method design and apply them to nursing curriculum.

Nowadays the rapid change in construction environment getting more globalized and complicated has caused lots of unexpected risks from inside and out of the country, so more sophisticated construction management strategies are being strongly needed. This paper suggests a risk management model with which we can estimate the appropriate contingency by quantifying the amount of probable risks immanent in large construction projects, which have a high degree of uncertainty in the anticipation of the total construction cost. To develop the model, the risk factors that make cost variations are elicited based on the real data of the contingencies assigned to the past projects. Furthermore, the influential relationship of risk factors is structured by applying the CRM(Cost Risk Model) which is the synthetic model of Monte Carlo Simulation, Influence Diagram and Decision Tree. The ultimate outcome of this research can by validated by tile case study with a large construction project performed.

Recently the design of SoCs(System-on-Chips) in which TCM is embedded for high speed operation increases rapidly. In this paper, a parallel test structure for eDRAM-based TCM embedded in SoCs is proposed. In the presented technique, the MUT (Memory Under Test) is changed to parallel structure and it increases testability of MUT with boundary scan chains. The eDRAM is designed in structure for parallel test so that it can be tested for each modules. Dynamic test can be performed based on input-output data. The proposed techniques are verified their performance by circuits simulation.

The methods of presenting information are more variable with advanced computer media technology. However, when we visualize information of database, it is more difficult to understand data meaning by complex date, which is not required by user. To compose new information, user needs to combine own his memory and new information presenting result. To be quickly explored new information and be exactly understood relationship of data structure, the data presenting of visualized information is more structured and presented with meaning form. It is possible to make information visualization system, which users can explore database by oneself, with supporting interaction to be able to control and combine relationship of three-dimensional scene graphic structure, presenting factors of animation and data structure of database. There are several diagrams, such as VR diagram, Form structure diagram and simulated diagram as the case study.

Purpose: This study was conducted to examine the effects of simulation education integrated with problem based learning (SIM-PBL) on clinical competency and self-efficacy in post operation nursing care for children. Methods: This study was a quasi-experimental design. Thirty six students in the third year of a 4-year baccalaureate nursing program were recruited conveniently and assigned to the control or intervention groups using time difference. Students were all in a pediatric nursing clinical practicum. The control group received the regular clinical practicum in a hospital setting. For the intervention group, a SIM-PBL education replaced 150 minutes of their clinical practicum. Results: The intervention group showed greater improvement in two areas of clinical competency compared with the control group; physical assessment (t= 3.019, p=.005) and post operation advice (t=2.428, p=.021). However, no statistically significant differences in improvement in any areas of self-efficacy were found between two groups. Conclusion: The results indicate that the SIM-PBL education is effective in improving some areas of clinical competence, but not self-efficacy in post operation nursing care for children. Further study is needed to develop SIM-PBL programs for various clinical topics and evaluate the effectiveness on the learning outcomes.

In the AEC(Architecture, Engineering and Construction) industry, BIM(Building Information Modeling) technology not only helps design intent efficiently, but also realizes an object-oriented design including building's life cycle information. Thus it can manage all data created in each building stage and the roles of BIM are greatly expanded. Contractors and designers have been trying to adopt BIM to design competitions and validate it for the best result in various aspects. Via the computational simulation which differs from the existing process, effective evaluation can be done. For this process, a modeling guideline for each kind of BIM tool and a validation system for the confidential assessment are required. This paper explains a new process about design evaluation methods and process using BIM technologies which follow the new paradigm in construction industry through complement points by an example of a competition activity of the Korea Power Exchange(KPX) headquarter office. In conclusion, this paper provides a basic data input guideline based on open BIM for automatic assessment and interoperability between different BIM systems and suggests a practical usage of the rule-based Model Checker.
