Due to Traffic accidents people faces health and economical casualties around the world. As the population increases vehicles on road increase which leads to congestion in cities. Congestion can lead to increasing accident risks due to the expansion in transportation systems. Modern cities are adopting various technologies to minimize traffic accidents by predicting mathematically. Traffic accidents cause economical casualties and potential death. Therefore, to ensure people's safety, the concept of the smart city makes sense. In a smart city, traffic accident factors like road condition, light condition, weather condition etcetera are important to consider to predict traffic accident severity. Several machine learning models can significantly be employed to determine and predict traffic accident severity. This research paper illustrated the performance of a hybridized neural network and compared it with other machine learning models in order to measure the accuracy of predicting traffic accident severity. Dataset of city Leeds, UK is being used to train and test the model. Then the results are being compared with each other. Particle Swarm optimization with artificial neural network (PSO-ANN) gave promising results compared to other machine learning models like Random Forest, Naïve Bayes, Nearest Centroid, K Nearest Neighbor Classification. PSO- ANN model can be adopted in the transportation system to counter traffic accident issues. The nearest centroid model gave the lowest accuracy score whereas PSO-ANN gave the highest accuracy score. All the test results and findings obtained in our study can provide valuable information on reducing traffic accidents.

The purpose of this study is to identify the expression methods of uncanny images shown in contemporary fashion through the visual expression methods of plastic arts. The study results are as following. First, there is a concept-forming element of 'The return of Repressed', which is a psychological mechanism for generating uncanny sets to the component of 'repression' and 'return'. 'Repression' herein consisted of 'unconsciousness', 'the other', and 'anxiety', while the return was composed of 'trauma' and 'repetition compulsion'. Second, there are visual expression methods of the uncanny in contemporary art. The subject of 'repressed things' was expressed as grotesque and having a terrible look. 'Fragmented body' was analyzed as 'dismantling' by mutilation, 'combination' placing cut body parts in other places, and 'damage' suffering from an illness or accident. 'Fear of death' was shown as 'anatomy' reminiscent of death and 'iconography of death' meaning return of the dead. 'Post-human' was a surrealistic being such as a monster and mechanized human, and was analyzed as 'gene variation' and 'cyborg'. Third, the methods of visual expression of the uncanny reflected on contemporary fashion was analyzed as 'fragmented body', 'fear of death', and 'post-human'. 'Fragmented body' appeared as the object reminiscent of the fragmented body, 'dismantling and combination of the body', and 'damage of the body' through the distortion of the clothing construction principle. 'Fear of death' visualized the characteristic elements of the subject reminiscent of death as 'iconography of death' and 'symbolic object of death' through the motif. 'Post-human' was the description of the subject beyond the body's function and form, and was shown as 'gene variation' and 'cyborg'.

An exhibitional suicide is a case of death that the purpose is to demonstrate one's own real intention for others. This exhibitional suicide has a few characteristics that are different from a suicide: seriousness of suicide intention, a method of suicide attempt, and the place of a suicide. In other words, an exhibitional suicide lacks suicide intention, uses a slower method of death, and attempts a suicide at the place which others can easily find. In this light, this paper ascertains that a fair number in poisoning deaths are an exhibitional suicide on the basis of the result of an autopsy by department of forensic medicine school of medicine, Kyungpook National University. The research also confirms that juveniles and women attempt a suicide as often as adults and men, and a great number of suicides are indeed an exhibitional suicide. In terms of a commercial law, many specialists see an exhibitional suicide as an accidental death. However, if we consider an exhibitional suicide as an accidental death, we cannot verify the authenticity of death in an accident. In addition, if we observe the purpose of insurance and suicide exemption period of insurance company, we rather get to know to distinguish an exhibitional suicide from an accident. According to the research, most of the exhibitional suicide results from little or no-relation with others. Therefore, a little interest from family, friend, and neighbor plays a pivotal role in preventing this suicide. Finally, an effort to build database concerning an exhibitional suicide by a psychological autopsy will help people access a plenty of statistical materials and facilitate further study about an exhibitional suicide.

Purpose: This study aims to examine what can be seen in children's paintings, their common characteristics, and what role art therapy plays in diagnosing the post-traumatic stress disorder in children who experienced trauma, through an art therapy program among elementary school students that witnessed the death of parents from a fire drill accident. Methods: A program of three times of art therapy was progressed among 34 children who witnessed a fire accident. Revised Children's Manifest Anxiety Scale (RCMAS) was used for comparative analysis of art therapy results. Results and Conclusion: First, children who had the possibility to develop post-traumatic stress disorder were found through art therapy. Second, an opportunity to express themselves were given to children who refused psychological tests or treatment through art therapy.

The shaking-off the dust from balustrade of higher stories may cause the higher risk of falling accident rate. Main purpose of this study was to quantify an effect of balustrade heights and blanket types on possibility of falling accident relative to one's motor controllability during shaking-off the dust of the blanket from balcony. Female participants, who consisted of total 10 under condition of balustrade height of 3 kinds (90 cm, 110 cm, 130 cm) and blanket types (0.4 kg, 1.6 kg, 3 kg, 200^⁎230 cm), performed repetitively the task of shaking-off the dust of the blanket. Vertical position and velocity of center of mass due to increase of blanket weigh in case of balustrade height of 90 cm was increased, but vertical ground reaction force was decreased swiftly. That is, the higher balustrade height was, the less distance difference between center of mass and center of pressure was.

Purpose: Purpose: The National Safety Experience Center Establishment and Reinforcement Project Management Guidelines, established to build a national safety experience center that is central to practicing education on disasters and safety accidents, requires that appropriate experience training programs be in place. However, due to the lack of classification grounds for the six areas of disaster•safety accidents presented by the Ministry of Public Administration and Security, and the mortality statistics necessary for establishing sectors have accumulated for over a decade, they are based on this. Our purpose is to standardize classification of sectors belonging to each area. Methods: We will divide disaster•safety accidents into 6 areas by three steps, and the grounds for 6 areas of accidents are presented. The 15 external causes other than the disease since 2009 has been proposed by The National Statistical Office. Therefore on the basis of these causes, various sectors belonging to each area are classified. Results: We will divide all disaster•safety accidents into six areas through three logical separation stages, and the areas were systematically classified based on the 15 factors of death. In conclusion, we present the grounds for the classification criteria in the six areas, the transportation accident disaster area in three areas, the social infrastructure system area in four areas, the crime accident disaster area in four areas, the life safety accident area in four areas, we set up all disaster•safety accidents in six areas and finally standardize total 25 areas.

Many local governments are reducing speed limits according to the "Safe Speed 5030" policy implemented by the government to reduce traffic accident deaths. In the urban road sections in many metropolitan cities where speed limit reduction is applied as a pilot project, the decrease effect of the traffic accident number and death count is shown; however, no study of the effect analysis on the road sections of medium and small cities (basic local government unit) is found. Therefore, this study investigated the travel speed, number of traffic accidents, and death count before and after the implementation of speed limit reduction, targeting some urban road sections in Pyeongtaek city and some provincial road sections in Icheon city among basic local governments, namely among medium and small cities in Seoul Metropolitan Area.

Gas system fire extinguishing equipment is a very economically useful facility, but if it is not used for a long period of time after installing the equipment, there is possibility of rupture due to corrosion of containers and operation errors of equipment systems, and this is very dangerous. However, it is impossible to experiment to check whether the equipment is operating normally. If gas is temporarily released into the enclosed space due to rupture and malfunction, it can cause serious human damage due to gas suffocation. In this study, based on the suffocation death accident of gas system fire extinguishing facility, the inflow path of released gas and the possibility of death and time to death were estimated using a 3D scan and FLACS.
