  • We investigated the neural correlates of accurate eyewitness memory retrieval using functional near-infrared spectroscopy. We analyzed oxygenated hemoglobin ($HbO_2$) concentration in the prefrontal cortex during eyewitness memory retrieval task and examined regional $HbO_2$ differences between observed objects (target) and unobserved objects (lure). We found that target objects elicited increased activation in the bilateral ventrolateral prefrontal cortex, which is known for monitoring retrieval processing via bottom-up attentional processing. Our results suggest bottom-up attentional mechanisms could be different during accurate eyewitness memory retrieval. These findings indicate that investigating retrieval mechanisms using functional near-infrared spectroscopy might be useful for establishing an accurate eyewitness recognition model.

  • We investigated event-related potentials (ERPs) to estimate the accuracy of eyewitness memories. Participants watched videos of vehicles being driven dangerously, from an anti-impaired driving initiative. The four-letter license plates of the vehicles were the target stimuli. Random numbers were presented while participants attempted to identify the license plate letters, and electroencephalograms were recorded. There was a significant difference in activity 300-500 milliseconds after stimulus onset, between target stimuli and random numbers. This finding contributes to establishing an eyewitness recognition model where different ERP components may reflect more explicit memory that is dissociable from recollection.

  • A Study on Problem of Impeachment Evidence in Criminal Proceedings for Employ by the Convergence Meaning of impeachment evidence in criminal proceedings is liking the spread of the branches moment. The first, there is to set limits of impeachment evidence. The amicable solution is to accept moving flexibly. In a concrete way must to make away with a constituent element unlawfulness. The second, problem a return to probative force exist. This problem agree in principle to resolve an issue for the testimony of an eyewitness. The third, how to admit that institution of criminal investigation after the testimony of an eyewitness exist. This attendant conditions are to eliminate illegality for the authenticity in he testimony of an eyewitness and for the observe due process. Therefore, we must observe due process without illegality to solve the problem for the convergence.

  • This paper was intended to examine the function of emotion that affects the accuracy of statements in the context of eyewitness testimony. The main emotion theories and concepts introduced in previous studies examining the relation between testimony accuracy and negative emotions were examined based on the characteristics of the research method. The results were presented in the order of emotion definition, emotion inducing method, and emotion measurement method. Specifically, the definition of emotion was described based on studies on negative emotions, arousal, stress, and mood. The emotion inducing method was mainly described based on images, virtual reality, and staged events designed by researchers, which have been mainly used in laboratories. Emotion measurement methods were described with respect to the self-report, behavioral checklist, and psychophysiology. In addition, the emotional approach for objective and scientific repeated verification, the importance of effective experimental design and appropriate scientific memory test, and the need for individual difference control were discussed. This paper reinterprets the contradictions shown by previous research by systematically structuring the function of emotion that affects the accuracy of testimony. It was meaningful to provide a frame for comparative analysis of related studies. Ultimately, it is expected that such knowledge will be used as basic documents for judging the reliability of eyewitness testimony in a legal context.

  • This investigation compared the eyewitness accounts of 5-year-old children by verbal-only inter views and interviews using anatomically neutral dolls. The verbal interviews consisted of free recall, specific question, and leading questions. While the overall accuracy of the interviews increased with the introduction of dolls as memory aids, the efficacy of the dolls was not uniform across types of interviews. In free recall, the dolls were not effective in eliciting accurate accounts. The use of dolls also did not compromise the memory of children in free recall which recalled greater number of correct details with the memory aids than without, but it should be careful in free recall could be reported exactly correct in spite of little bit amounts. Responses to leading questions showed that the children were affected by suggestive misleading question and were susceptible to incorporation of that information into their memory.

  • The frequency of car accidents is very high at the intersection. Because of the state of a traffic signal, quarrels happen after accidents. At night many cars run away after causing an accident. In this case, accident analyses have been conducted by investigating evidences such as eyewitness accounts, tire tracks, fragments of the car or collision traces of the car. But these evidences that don't have enough objectivity cause an error in judgment. In the paper, when traffic accidents happen, the traffic accident detection system that stands on the basis of images and sounds detects traffic accidents to acquire abundant evidences. And, this system transmits 10 seconds images to the traffic center through the wired net and stores images to the Smart Media Card. This can be applied to various ways such as accident management, accident DB construction, urgent rescue after awaring the accident, accident detection in tunnel and in inclement weather.

  • The big problem of accidents at sea is negligent watch, it causes collision, fender bender, stranding, rollover, and sinking of fishing vessel. Most accidents happens without an eyewitness, it is difficult to identify the cause of the accident. VDR(: Voyage Data Recorder) is needed to identify a cause of the accident, the VDR is not usually used for fishing vessel because of high cost. Thus, this paper designs and develops a VDR system for fishing vessel. If the system is used, cause of a sea accident can be quickly identified. Also, a VDR system can be used for appropriate measures to fix a cause of the accident. Finally, it also can be helpful to prevent maritime accidents.

  • In this paper, we introduce a target position reasoning system based on Bayesian network that selects destinations of robots on a map to explore compound disaster environments. Compound disaster accidents have hazardous conditions because of a low visibility and a high temperature. Before firefighters enter the environment, the robots notify information in advance, such as victim's positions, number of victims, and status of debris of building. The problem of the previous system is that the system requires a target position to operate the robots and the firefighter need to learn how to use the robot. However, selecting the target position is not easy because of the information gap between eyewitness accounts and map coordinates. In addition, learning the technique how to use the robots needs a lot of time and money. The proposed system infers the target area using Bayesian network and selects proper x, y coordinates on the map based on image processing methods of the map. To verify the proposed system, we designed three example scenarios based on eyewetinees testimonies and compared time consumption between human and the system. In addition, we evaluate the system usability by 40 subjects.

  • This study analyzed the flame characteristics when igniting 200 ml of flammable liquids containing equal parts gasoline and another flammable liquid. These mixtures were used to fill a divided space in a simulation. The length of one side of the divided space was 2,000 mm, and the length of the combustion device was 1,000 mm. The mixture with alcohol had the highest flame propagation speed (0.7 s), while the mixture with light oil showed the lowest (1.2 s). The gasoline and acetone mixture reached peak flame in 25.5 s, at the highest speed, while the mixture with light oil reached peak flame in 163.7 s at the lowest speed. The gasoline and light oil showed the longest continuous combustion time (332.7 s), while the gasoline and paint thinner showed the shortest (121.5 s). A fire inspector who is examining the scene of a fire needs to analyze both the statements of the first eyewitness and the flame characteristics collectively.

  • Joseph Mallord William Turner (1775-1851) has been widely regarded as the most original and brilliant English landscape painter in the 19th century. Admitted to the Royal Academy Schools in 1789, Turner was a precocious artist and gained the full membership of the prestigious Royal Academy in 1802 at the age of 27. Already in the 1800s he was recognised as a pioneer in taking a new and revolutionary approach to the art of landscape painting. Among his early works made in this period, The Shipwreck, painted in 1805, epitomizes the sense of sublime Romanticism in terms of its dramatic subject-matter and the masterly display of technical innovations. Of course, the subject of shipwreck has a long standing history. Ever since human beings first began seafaring, they have been fascinated as much as haunted by shipwrecks. For maritime societies, such as England, shipwreck has been the source of endless nightmares, representing a constant threat not only to individual sailors but also to the nation as a whole. Unsurprisingly, therefore, shipwreck is one of the most popular motifs in art and literature, particularly during the 18th and 19th centuries. Yet accounts, images and metaphors of shipwreck have taken diverse forms and served different purposes, varying significantly across time and between authors. As such, Turner's painting registers a panoply of diverse but interconnected contemporary discourses. First of all, since shipwreck was an everyday occurrence in this period, it is more than likely that Turner's painting depicted the actual sinking in 1805 of the East India Company's ship 'The Earl of Abergavenny' off the coast of Weymouth. 263 souls were lost and the news of the wreck made headlines in major English newspapers at the time. Turner's painting may well have been his visual response to this tragedy, eyewitness accounts of which were given in great quantity in every contemporary newspaper. But the painting is not a documentary visual record of the incident as Turner was not present at the site and newspaper reports were not detailed enough for him to pictorially reconstruct the entire scene. Rather, Turner's painting is indebted to the iconographical tradition of depicting tempest and shipwreck, bearing a strong visual resemblance to some 17th-century Dutch marine paintings with which he was familiar through gallery visits and engravings. Lastly, Turner's Shipwreck is to be located in the contexts of burgeoning contemporary travel literature, especially shipwreck narratives. The late 18th and early 19th century saw a drastic increase in the publication of shipwreck narratives and Turner's painting was inspired by the re-publication in 1804 of William Falconer's enormously successful epic poem of the same title. Thus, in the final analysis, Turner's painting is a splendid signifier leading the beholder to the heart of Romantic abyss conjoing nightmarish everyday experience, high art, and popular literature.
