The purpose of this study was to identify the factors affecting perceived safety climate and the level of incident reporting attitude, incident reporting knowledge and safety climate. The data were collected by structured questionnaires from 240 nurses and were analyzed with descriptive statistics, t-test, ANOVA, Scheffe test, Pearson's correlation coefficients and multiple regression. The level of incident reporting attitude and incident reporting knowledge was 3.34 and 3.05. The level of safety climate was 3.25. Incident reporting knowledge and safety climate have a significant positive association with incident reporting attitude(r=.33, p<.001; r=.38, p<.001). Incident reporting knowledge was positively associated with safety climate(r=.32, p<.001). Factors influencing safety climate were incident reporting knowledge, belief in improvement and reporting intention which explained 24.7% of the variance(F=12.22, p<.001). The findings indicate that to improve incident reporting knowledge with positive attitude and safety climate should be considered as patient safety strategy and should endeavour to develop interventions for safety.

Wave field measurements were made over a period of 18 days to study the spatial distribution of incident wave on seaweed tarm field around Gumil-up Sea, Wando, Korea. These measured data were compared with data from the Geomun-do ocean weather/wave observation buoy. A numerical simulation model that combined the offshore design wave with the seasonal normal incoming wave was used to study the incident wave distribution surrounding a seaweed farm. The results are summarized as follows. (1) On-site wave measurements showed that the major relationship between maximum and significant wave height was $H_{max}=1.6H_{1/3}$. (2) Offshore incident wave energy reaching the coast was greatly influenced by the wind direction. A north wind reduced the incident wave energy and a south wind increased it. (3) The calculated maximum wave height under the design wave boundany conditions was in the range of 4~5 m and the reduction in the incident wave height ratio ranged from approximately 38.1% to 47.6% at Gumil-up Sea. Under normal wave conditions, the maximum wave heights were 3.6~4.0 m in summer and 2.3~2.7 m in winter while the reduction in the incident wave height ratio was about 41.8% to 49.1%. (4) The sea state in the southern area of Gumil-up was the most affected by ocean waves, whereas the sea state in the northern area was very stable. The significant wave ratio in the south was about six times that in the north.

The term "incident duration time" is defined as the time from the occurrence of incident to the completion of the handling process. Reductions in incident durations minimize damages by traffic accidents. This study aims to develop models to identify factors that influence incident duration by investigating traffic accidents on highways. For this purpose, four models were established including an integrated model (Model 1) incorporating all accident data and detailed models (Model 2, 3 and 4) analyzing accidents by location such as basic section, bridges and tunnels. The result suggested that the location of incident influences incident duration and the time of arrival of accident treatment vehicles is the most sensitive factor. Also, significant implications were identified with regard to vehicle to vehicle accidents and accidents by trucks, in night or in weekends. It is expected that the result of this study can be used as important information to develop future policies to manage traffic accidents.

Purpose: This study aimed to investigate perception of patient safety culture, incident reporting, and safety care activities among clinical nurses and to identify factors associated with the safety care activities. Methods: Structured questionnaires were used to collect data from 155 nurses who were involved in direct patient-care. Results: Descriptive statistical anaylses revealed that the mean score of patient safety culture was $3.26{\pm}0.32$ and $4.19{\pm}0.41$ was for the safety care activities. In incident reporting, reporting intention ($3.56{\pm}0.68$), belief in improvement ($3.42{\pm}0.60$), worry about appraisal ($3.37{\pm}0.65$) and reporting knowledge ($3.36{\pm}0.72$) respectively. Correlational analyses showed that perceived patient safety culture (r=.36), reporting intention (r=.34), belief in improvement (r=.32), and the knowledge (r=.38) in incident reporting were positively correlated with safety care activities, while the worry about appraisal in incident reporting attitude was negatively correlated. The factors associated with safety care activities were incident reporting knowledge (${\beta}=.31$, p<.001), supervisor/managers' attitudes toward patient safety culture (${\beta}=.29$, p<.001), belief in improvement of incident reporting attitude (${\beta}=.16$, p=.041). Conclusion: These results suggest that to improve safety care activities among hospital nurses, it is necessary to educate nurses on incident reporting. Also, a system-level approach is needed to support leadership in patient safety and to provide positive feedback on incident reporting.

Recent advances in artificial intelligence (AI) technology have enabled the integration of AI technology into image sensors, such as Closed-Circuit Television (CCTV), to detect specific traffic incidents. However, most incident detection methods have been carried out using fixed equipment. Therefore, there have been limitations to incident detection for all roadways. Nevertheless, the development of mobile image collection and analysis technology, such as image sensors and edge-computing, is spreading. The purpose of this study is to estimate the reducing effect of the incident detection time according to the introduction level of mobile image collection and analysis equipment (or connected vehicles). To carry out this purpose, we utilized data on the number of incidents collected by the Suwon branch of the Gyeongbu expressway in 2021. The analysis results showed that if the market penetration rate (MPR) of connected vehicles is 4% or higher for two-lane expressway and 3% or higher for three-lane expressways, the incident detection time was less than one minute. Furthermore, if the MPR is 0.4% or higher for two-lane expressways and 0.2% or higher for three-lane expressways, the incident detection time decreased compared to the average incident detection time announced by the Korea Expressway Corporation for both two-lane and three-lane expressways.

Predicting the incident clearance time is important for eliminating the high transportation costs and congestion from non-repetitive congestion caused by incidents. In this study, the factors influencing the clearance time suitable for domestic road conditions were analyzed, using a training dataset for predicting the incident clearance time using artificial neural networks. In a previous study, the under-prediction problem for high incident clearance time was used. In the present study, over-sampling training data applied using the SMOGN technique was obtained and applied to the model as a solution. As a result, the DNN model applying the SMOGN technique could compensate for the limitations of the previously developed prediction model by predicting the clearance time with the highest accuracy among the models developed in the research process with MAE = 18.3 minutes.

Nuclear power provides 30% of our country's power, which acts as one of the most important power sources. But on March 11, 2011, the earthquake that hit Northeast Japan with a 9.0 magnitude, known as the Fukushima Reactor Leak Incident has created fear in the public's mind that 'nuclear power is unstable'. The reason for such distrust are many but inaccurate reports of the incident by the media has added to the fear. This paper will analyze the contents of the media report of the heavy water leakage in reactor 3 at the Wolsong Nuclear Power Plant on October 4, 1999 to discover the problematic areas and ascertain a more appropriate method of media coverage.

The human genome project decoded 99% of human genes for $ 3 billion by 1990-2003. However, as many studies on genes have progressed, it has become clear that there are many cases where diseases occur without structural alteration of genes. The latest study, Epigenetics, has come up with the answer to this problem. The famine that hit Jeju until 1670-1795, the ban on the exclusion of Jeju Island to the outside 200 years of suffering, and in 1948, one third of the citizens were killed by the 4.3 incident generate Epigenetic. It has been shown in the world history science that starving-stress can be manifested as obesity and disease in progeny due to hereditary phenomena. 5G-based healthcare IoT technology can be used for the treatment of obesity by enabling Epigenetic analysis of this phenomenon.
