Since then the aviation industry developed dramatically through the two world wars. As these high-performance aircraft were developed, pilots' training has also changed. While initial pilots' training focused on acquiring the navigation and flight skills necessary for pilots to fly an aircraft, nowadays current training focuses on understanding the system, situation awareness and decision making accordingly, and human factor management among the pilots. The result of pilot training that has achieved continuous change and development is the current Evidence-Based Training. This study aims to determine how situation awareness, problem solving and decision making and workload management, which are core elements of Evidence-Based Training, affect pilot's resilience for safe aircraft operation, and to reflect this in the development and composition of Evidence-Based Training programs to contribute to improving the resilience of individual flight crew members.

This paper is about MPEG-4 error resilience tools of video streaming on packet service(ex, Internet). It is need to packetization for MPEG-4 video transport by packet unit on MPEG-4 system, this paper suggest packetization method of minimizing packet error on packet service[1]. FEC(Forward Error Correction) and retransmission is usually used for recovery of packet loss, and this paper suggest applying these method to DMIF(Delivery Multimedia Integration Framework) for minimizing packet loss[2].

Error resilience for image coding is an important component of multimedia communication system. Error resilience schemes address loss recovery from the compression perspective. Multiple description coding (MDC) is one of the error resilience techniques promising for robust video transmission. It is the way to achieve tradeoff description such as scalar quantization, correlating transform and the quantized frame expansion. In this paper, we consider Multiple Description Scalar Quantization (MDSQ) to wavelet domain. Conventional MDSQ schemes considered description with equal weights in each sub-bands. But, we can see that the each sub-bands is unequal contribution to whole image quality. Therefore, we experiment the multiple design MDSQ table to make probability of zero index high, which gives high efficiency in arithmetic symbol coder. We also compare our proposed method with the conventional methods and show improved performance in terms of redundancy-rate-distortion.

Safety culture is a collection of the beliefs, perceptions and values that employees share in relation to risks within an organisation. On the other hand, a resilient safety culture (RSC) means a culture with readiness of the organisation to respond effectively under stress, bounce back from shocks and continuously learn from them. RSC helps organisations to protect their interest which can be attributed to behavioural, psychological and managerial capabilities of the organization. Quantification of the degree of resilience in an organisation's safety culture can provide insights about the strong and weak links of the organisation's overall health and safety situation by identifying potential causes of system or sub-system failure. One of the major challenges of quantification of RSC is that the attributes that determine RSC need to be measured through constructs and indicators which are complex and often interrelated. In this paper, we address this challenge by applying a fault tree analysis (FTA) technique which can help analyse complex and interrelated constructs and indicators. The fault tree model of RSC is used to evaluate resilience levels of two organisations with remote and urban locations in order to demonstrate the failure path of the weak links in the RSC model.

Resilience is the capacity to maintain essential services under a range of circumstances from normal to extreme. It is achieved through the ability of assets, networks, systems and management to anticipate, absorb and recover from disturbance. It requires adaptive capacity in respect of current and future risks and uncertainties as well as experience to date. The agricultural infrastructures with high resilience can not only reduce the size of the disaster relatively, but also minimize the loss by reducing the time required for recovery. This study aims to evaluate the most suitable drought countermeasures with the analysis of various resilience indices by predicting future agricultural water shortage under land use and climate change scenarios for agricultural areas in Jeju Island. The results showed that the permanent countermeasure is suitable than the temporary countermeasures as drought size and the cost required for recovery increase. Wide-area water supply system, which is a kind of water grid system, is identified as the most advantageous among countermeasures. It is recommended to evaluate the capability of agricultural infrastructure against drought with the various Resilience Indices for reliable assessment of long-term effect.

Terrestrial DMB(Digital Multimedia Broad-casting) system that is now under standardization in Korea offers multimedia broadcasting services at mobile environment and is based on Eureka-147 DAB(Digital Audio Broadcasting) for transmission method. Also DMB provides the error protection method of convolution coding. In this paper, we study on the effective error resilience coding of MPEG-4 video stream over DMB system. In our algorithm, the first, we partition the MPEG-4 data using the MPEG-4 data partitioning method, and then controls the convolution coding rate according to the importance of the partitioned data. From our simulation result, we show that our algorithm is proper for terrestrial DMB services.

Purpose: This study aimedto develop a structural equation model on the relationship among ego-resilience, and teaching effectiveness on clinical education, stress coping style, perceived family support, and satisfaction of clinical practice in nursing students in order to increase the satisfaction of clinical practice. Methods: The subjects were 399 undergraduate nursing students enrolled in 7 universities and participating in 10 clinical practice setting areas in 5 cities in South Korea. The research was conducted from December 5th, 2009 to February 20th, 2010. The structural equation model was used to perform the analysis with the statistics program of SPSS win 17.0 and AMOS 5.0. Results: Teaching effectiveness and family support showed a direct effect on satisfaction of clinical practice, while ego-resilience and stress coping styles showed an indirect effect. The biggest total effect on satisfaction of clinical practice was teaching effectiveness followed by family support, ego-resilience, and stress coping styles respectively, which accounted for 50.9%. Conclusion: Based on outcomes of this study, the proposed model allows better understanding of the satisfaction of clinical practice. This result implies that strategies or intervention programs enhancing extrinsic protection factors, motivation factors, and intrinsic protection factors should be considered. In addition, a structural support system for increasing the satisfaction level of clinical practice in nursing students should also be considered.

Purpose: This study investigated the correlations among resilience, the awareness of patient safety management, proactive behavior, and the performance of standard precautions among nurses working in the emergency department. Additionally, it aimed to identify the factors influencing the performance of standard precautions. Methods: Data were collected through a descriptive survey conducted between June 10 and July 9, 2023. The participants included 208 nurses working in the emergency department in Korea. The collected data were analyzed using SPSS/WINdows software version 29.0, based on the frequency, percentage, mean, standard deviation, t-test, one-way analysis of variance, Scheffé test, Pearson's correlation coefficients, and multiple regression. Results: The analysis based on the participants' general characteristics showed that performance of standard precautions varied significantly according to age (t=2.10, p=.036), size of the emergency department (F=7.46, p<.001), average number of patients treated per day while working in the past month (t=-3.88, p<.001) and standard precautions training experience (t=2.16, p=.032). The main factors influencing the performance of standard precautions among nurses working in the emergency department are awareness of patient safety management (β=.62, p<.001), resilience (β=.18, p=.042), and age (β=-.15, p=.007), with a total explanatory power of approximately 46.0%. Conclusion: It is necessary to establish programs and an effective education system to increase resilience and awareness in patient safety management to improve the performance of standard precautions among nurses working in the emergency department.
