The purpose of this paper is to report gas fire accident based on classification of the major gas fire causes (including handling mistakes, inferior goods, etc.), fire classifications (fire, explosion, leakages, etc.), damage levels(1st, 2nd, 3rd, 4th grade levels), casualties (death, serious wound, slight injury) since gas fire has been generated according to growth of gaseous fuel consumption on home and enterprises with various accident causes. Among gaseous fuels, LPG facility can be c1assified as gas container, pressure regulator, gas hose, interim valve, combustion port. Any fire or any explosion can be caused from handling mistakes, inferior goods on each parts as stated above. Exact gas fire causes shall be identified based on previous case studies on similar fires with consideration of lesson learns.

This study was performed to determine the causes of the bursting casualties such as death of sows and piglets, abortion, still birth and infertility in a pig farm after consecutive detonation for three months to construct 345 KV in Kimje area. 1. Temperatures in Kimje district, management condition, microorganism in the feed, inbreeding, hematological conditions, and viral agent causing abortion were not proved as the factors of acute occurrence of abortion and infertility in the pig farm. 2. The amount of explosive was increased from 250 kg to 1,100 kg from 23 Dec. 1996 to 28 Jan. 1997 and at the same time the distance between the spot of detonation and the pig farm got closer, from 200 m at the begining to 100 m at the last detonation. 3. Theoretical concussion and sound values were 0.66 kine and 89.39 ㏈, respectively, in the case of 100 m distance between the detonation spot and the pig farm. In conclusion, death of 675 piglets and 11 sows and infertility of 69 sows in the pig farm were assumed to be caused by the concussion or sound stress after detonation.

Last year, over 800 Australian live cattle were imported, underwent quarantine procedure for one month in the port of Incheon and Busan and distributed to general farm house holds in Gyeongju city, Gyeongbuk province, and Gimhae city, Namhae county, Gyeongnam province. But Hanwoo association took violent actions to prevent from entering the country for fear that the imported live cattle would destroy the 'Hanwoo industry', and in turn leads to the collapse of the industry. In Australia, national animal protection body 'Animals Australia' investigated the level of cruelty involved in this trade and made a report 'The death file'. Australia governments drive to expand Its market for 'live animal exports' and it has resulted in a corresponding increase In casualties associated with the long-haul overseas trade in live livestock animals over the past years. After the stress of transportation, all the surviving cattle and sheep face death on foreign soil, many into countries which have no animal welfare laws or, at best, inadequate laws. They will usually be killed without pre-stunning and often even without adequate restraint facilities. The result is inherent and persistent suffering. West Australian(WA) Police acting on behalf of the West Australian Government and the Office of the WA State Solicitor have laid animal cruelty charges against a leading WA live export company for breaching the WA Animal Welfare Act. With the aim of eventually substituting it for the live sheep trade, the Senate Select Committee on Animal Welfare (SCCAW) recommended that the Federal Government 'promote and encourage the expansion of the refrigerated sheep meat trade to the Middle East and other countries'. Animal welfare standards have been improved time after time, there is another incident, another public outcry, another inquiry and more assurances.

Over the past two decades suicide terrorism has become an ever-widening phenomenon. When suicide terrorism was first introduced in the Middle East it seemed that this new phenomenon was invincible and that it might change the innate imbalance between terror groups and their rivalry governments. This did not in fact occur. Looking at history of terrorism, it can be seen that suicide attacks are in actuality a very old modus operandi. However, contemporary suicide terrorism differs from such historical tactics, just as the whole phenomenon of terrorism differs from ancient modes of warfare. Modern suicide terrorism is aimed at causing devastating physical damage. through which it inflicts profound fear and anxiety. Its goal is to produce a negative psychological effect on an entire population rather than just the victims of the actual attack. The relatively high number of casualties guaranteed in such attacks, which are usually carried out in crowded areas, ensures full media coverage. Thus, suicide terrorism, ranks with other spectacular modus operandi such as blowing up airplanes in mid air or the use of Weapons of Mass Destruction as a sure means to win maximum effect. For the purposes of this paper a suicide terror attack is defined as a politically motivated violent attack perpetrated by a self-aware individual (or individuals) who actively and purposely causes his own death through blowing himself up along with his chosen target. The perpetrator's ensured death is a precondition for the success of his mission. The greatest potential risk suicide terrorism may pose in future is if terrorists carry out operations combined with other spectacular tactics such as blowing up airplanes or the use of Weapons of Mass Destruction. Such a combination will increase immensely the death toll of a single terror attack and will have a shocking psychological effect on public moral. At this level suicide terrorism would constitute a genuine strategic threat and would probably be confronted as such. This study portrays a general overview of the modern history of suicide terror activity worldwide, focusing on its main characteristics and the various aims and motivations of the terror groups involved. In addition, This study provides an overview what is to be done to prevent such terrorist attacks.

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.

Background: Febrile neutropenia (FN) is a serious complication following chemotherapy and is associated with significant mortality and financial expenditure. The aim of this study was to evaluate risk factors for longer length of stay (LOS) and mortality and cost of treatment among hospitalized adults with cancer who developed febrile neutropenia in Thailand. Materials and Methods: Information on illness of inpatients and casualties came from hospitals nationwide and from hospital withdrawals from the 3 health insurance schemes in fiscal 2010. The data covered 96% of the population and were analyzed by age groups, hospital level, and insurance year schemes in patients with febrile neutropenia. Results: A total of 5,809 patients were identified in the study. The mortality rate was 14%. The median LOS was 8.67 days and 69% of patients stayed for longer than 5 days. On bivariate analysis, age, cancer type, and infectious complications (bacteremia/sepsis, hypotension, fungal infections, and pneumonia) were significantly associated with longer LOS and death. On multivariate analysis, acute leukemia and infectious complications were linked with longer LOS and death significantly. The median cost of hospitalized FN was THB 33,686 (USD 1,122) with the highest cost observed in acute leukemia patients. Conclusions: FN in adult patients results in significant mortality in hospitalized Thai patients. Factors associated with increased mortality include older age (>70), acute leukemia, comorbidity, and infectious complications.

Sin Dae-woo was a scholar representing the Ganghwa School in the late Joseon Dynasty. He was Jeong Je-du's grandson-in-law and also in charge of organizing Jeong Je-du's collection of writings. His three sons had a particularly close relationship with their father, so even when they published a collection of writings after his father's death, the names of the three were combined and marked as Jin-jak-shin. The records they left include Seokcheon Il-seung, who described the history of the family along with the collection of writings, Seongdo Il-rok, a diary of the time of Seongcheon Busa, and many letters exchanged over time. These records draw attention as they contain records of medical life, such as eye diseases that the family suffered, infectious diseases that caused many casualties, and Yakro (distilled herbal essence) that showed records of being used for treatment at the time. In this paper: 1) We examine the medicines, prescriptions, acupuncture, and medication used to treat eye diseases. 2) We carefully examine the epidemic, the responses of the parties to it, and the attitudes of those who stood at the boundary between death and life. 3) We look for clues to the use of Western-origin drugs called Yakro. Intellectuals of the time looked deeper into Lee Kyugyung's book and Seo Yu-gu's book on how they were reflected in Joseon's medical life. In conclusion, in the 18th and 9th centuries, we see that the influential families of the Ganghwa school freely brought in famous acupuncturists, used prescriptions that were included in medical books or not, and used Yakro from western origin that were not traditional methods of Joseon. Thus, we reveal that doctors of the Joseon had the capacity to pursue their medical life more actively and had open-minded exchanges than our existing perceptions.

This study is a study to estimate the VSL (Value of a Statistical Life) and CBA (Cost-benefit analysis) of the rollover safety standard for hydrogen buses, VSL is an economic value concept used to quantify the benefits of avoiding death. CBA shows the effect of cost-benefit, and if B/C is greater than 1, there is a social effect. In order to estimate the VSL and CBA, the hydrogen bus introduction scenario was assumed to be optimistic (20,000 vehicles in 2030), neutral (15,000 vehicles in 2030), and pessimistic (10,000 vehicles in 2030), and the effect of reducing human casualties was estimated. As a result, except for the pessimistic market situation of introducing hydrogen buses (10,000 vehicles in 2030) and the VSL reduction ratio of 10%, all policies were judged to have high cost-benefit effects. These results indicate that the introduction of the rollover safety standard for hydrogen buses is a socially effective policy.

Recently, the casualties of automobile traffic accidents are rapidly increasing, and serious accidents involving serious injury and death are increasing more than those of ordinary people. More than 70% of major accidents occur in drowsy driving. Therefore, in this paper, we studied the drowsiness prevention system to prevent large-scale disasters of traffic accidents. In this paper, we propose a real-time flicker recognition method for drowsy driving detection system and drowsy recognition according to the increase of carbon dioxide. The drowsy driving detection system applied the existing image detection and the deep running, and the carbon dioxide detection was developed based on the IoT. The drowsy prevention system using both of these techniques improved the accuracy compared to the existing products.

The following matters were confirmed through the analysis of casualties due to fires in Korea, Japan, and the U.S. in this paper. 1 Korean statistics are not the most detailed of the three countries about casualties due to fires, so we need to have detailed statistics of them on casualties more. 2. Korean deaths are the lowest by 10-11 people due to fires per one million of population. Those of Japan are 15-17 and about 12 people in the U.S.; decreased about 2/3 only for a quarter of a century. 3. Korean deaths are on the decrease about 1.5 people per 100 cases due to fires,3.5 in Japan and 0.2-0.3 in the U.S. Likewise, Korean injuries are on the decrease per 100 cases due to fires From 14.9 in 1977 to 5.1 in 2001 and 5.3 in 2002. In the U.S., the figure was 1.0-1.6. but after the year 1994, it was 1.2 or so. It tends to some increase to 2.6-2.8 in Japan. Therefore, when fires are happened, the death probability is the highest in Japan and 15 times higher than that of the U.S. The injury probability is the highest in Korea and 5 times higher than that of the U.S. 4. Fire deaths rate is the highest in the U.S. about $80\%$ due to home fires (including apartments) among all deaths. Japan tends to decrease of $55\%$. Recently, in case of Korea. it is similar level to that of Japan. 5. Korean aged people of 65 years old and over exceeded by $7\%$ in 2000 and entered an aging society, so It Is time to Investigate and take effect policies to reduce the death of the aged . Japan has ahead a super-aged society that exceeds $20\%$ of the people over the age 65, and many of them die of fire. Consequently, Japan has taken effect policies to reduce deaths from 10 years or more than before. Therefore, it is a good proposal to analyze the policies of Japan deeply and study introduction of them.
