Autoimmune hemolytic anemia is a disease characterized with destruction of erythrocytes as a result of antibody produce against patient's own erythrocytes and anemia. Autoimmune hemolytic anemia can be roughly stratified into two groups according to serological features and secondary causes including drugs induced hemolytic anemia. Drugs induced autoimmune hemolytic anemia is very rare in pediatric patients. Even though hematological side effects such as leucopenia, agranulocytosis, eosinophilia, thrombocytopenic purpura and aplastic anemia might occur due to psychotropic drug use; to the best of our knowledge there is no autoimmune hemolytic anemia case due to quetiapine, an atypical antipsychotics, in literature. We hereby describe the first child case of autoimmune hemolytic anemia during quetiapine treatment.We also are pointing out that one should keep in mind serious hematological side effects with atypical antipsychotic drug use with this case report.

Penetrating cerebral injuries caused by foreign bodies occur rarely due to the substantial mechanical protection offered by the skull. Throughout most of history, the brain, residing in a "closed box" of bone, has not been vulnerable to external aggression. Recently, we encountered a serious penetrating craniocerebral injury caused by a nail gun. Total excision of the offending nail via emergency craniotomy was performed, but the patient's neurologic status was not improved in spite of aggressive rehabilitative treatment. Here, we report on this troublesome case in light of a review of the relevant literature.

This study includes a case study among plastic process manufacturing companies, based on which, the currently used 4M method is applied in terms of machine, media, man, and management, to conduct quantitative risk evaluation, and thus to contribute to reducing human and material loss as well as preventing accidents in industrial fields. The result of this study is analyzed based on the 4M-risk assessment to find out the hazardous risk elements, and the quantitative evaluation made it predictable the value of risk(frequency $\times$ intensity) in such classified levels as serious risk, critical risk, and intolerable risk. Further, Among the businesses with hazardous risk elements and high frequency of industrial disaster, risk analysis was conducted for each process, and as a result, 38 cases among 76, including those of serious risk, critical risk, and intolerable risk, were improved, and the risk was reduced. Besides, it is thought that with the engineering approach with 4M-Risk Assessment, the attempt to improve safety level contributes to prevention of accidents.

With rapid urbanization, various problems have been occurred in the city. The most serious one is dwelling. The gap of income between the rich and the poor resulted in deteriorating the pattern of the house consume. In case of developing a bad residential area, this area is changed into a new residential area, but the dweller, who lived in the bad area, may move into the outskirts of the city. This means that a bad residential area is sprawled and spreading. Therefore. the rescue plan of the existing dweller according to urban redevelopment were suggested in this study.

The generators of a small size below 100Kw are often used as power suppliers for emergency only in most domestic telecommunication companies. Serious twisted waves occur due to the inflow of harmonies from the generator into a S-type rectifier. And the increasing by stages of load upon the rectifier end up a stoppage of power supply during the serious hunting, which makes it difficult to supply power securely on the other part as well as that of communications. In case of long time of power failure the generators of a small size will be essential because the battery for emergency has a limit in capacity. Therefore it is necessary to solve the problems concerning the generators. This study is focused on the identifying and solving the problem including use of SCR elements connected to the generators.

One of the most serious promblems in the concrete structures is cracking failure due to the several complicated reasons. These cracks are not only serious structural problems, but also lower the durability and deteriorate the structural shape, which cause the reinforcement rust in the open air and sea water. An analytical study was undertaken to investigate the cracking problems in the one of concrete caissons using Finite Element Method. This caisson is modelled with plate elements and truss elements for the walls and lifting cables respectively and analyzed in the every construction stages, such as lifting, moving, sinking, filling, towing, setting, and proposed reasonable construction methods for the concrete caisson structures.

The failures in the power plant can lead to a dangerous situation according to the demand and supply of the electric power. The failure times of the domestic plant happens very often, and it has been reported as a significant loss by the power sales. Therefore, the power plant is demanded to maintain very well in order to produce a high quality of power. The rate of failures by the electricity facility is filled with 40[%] among the trouble in the failures of the power plant. The failures of power plant can cause serious accidents, magnificent losses, and chaos in our society. So, we require a significant plan to reduce such a serious problem. In this paper, I analysis the failure case of power converter in power plant, and I offer the better solution to be able to prevent the failures from power plant.

Conservative therapy with appropriate antibiotics is essential for most patients with infectious spondylitis. Although most antibiotics do not cause problems if it used properly and serious side effects are rare, side effects can occur with any class of drugs and adverse reactions of antibiotics can range from mild allergic reactions to serious and fulminant adverse events. These side effects are also extremely variable from patient to patient and from antibiotic to antibiotic. A side effect of antibiotics may paradoxically increase inflammatory marker levels. Here, the author presents two cases of antibiotic-induced increase in inflammatory markers in cured infectious spondylitis. The patients were successfully treated after stopping the antibiotic therapy. The differential diagnosis between antibiotic side effects and infection should be considered very carefully because the treatment is completely different. Although the exact mechanisms underlying successful treatment without antibiotics are unclear, we should consider the side effects of antibiotics when following inflammatory markers during treatment of infectious spondylitis.

Conflicts in public construction projects become more serious and complex so that they have a negative effect on performance of projecets. Conflicts in public construction projects are defined as expanding in complaints. This study analyzes the relationship structure and effect on performance between complaints and conflicts. First of all, 219 survey data collected from industry experts were used to derive complaints arising from the project and to understand the characteristics of each complaint. In the case of environmental damages, rather than environmental damage during construction, harmful substances or effects that can occur in completed facilities cause complaints from local residents, and opposition from environmental groups has a great effect on time and cost increase. As for safety damage, civil complaints related to prevention and countermeasures for safety accidents occur frequently, and additional construction affects cost increases. Through this study, it is possible to understand the serious complaints that are prone to conflict in public construction projects, their frequency, and the performance of the project.

As with land crops, cultivated algae are affected by various diseases ranging from large outbreaks of a disease to chronic epiphytes, which may downgrade the value of the final product. The recent development of intensive and dense mariculture practices has enabled some new diseases to spread much faster than before. A new disease is reported almost every year, and the impact of diseases is expected to increase with environmental change, such as global warming. We observed the incidence of diseases in two Pyropia sea farms in Korea from 2011 to 2014, and estimated the economic loss caused by each disease. Serious damage is caused by the oomycete pathogens, Pythium porphyrae and Olpidiopsis spp., which decreased the productivity of the Pyropia sea farms. In Seocheon sea farms, an outbreak of Olpidiopsis spp. disease resulted in approximately US $1.6 million in loss, representing approximately 24.5% of total sales during the 2012-2013 season. The damage caused by green-spot disease was almost as serious as oomycete diseases. An outbreak of green-spot disease in the Seocheon sea farms resulted in approximately US $1.1 million in loss, representing 10.7% of total sales in the 2013-2014 season in this area. However, the causative agent of green-spot disease is still not confirmed. "Diatom felt" is regarded as a minor nuisance that does not cause serious damage in Pyropia; however, our case study showed that the economic loss caused by "diatom felt" might be as serious as that of oomycete diseases. Bacteria and cyanobacteria are indigenous members of epiphytic microbial community on Pyropia blades, but can become opportunistic pathogens under suitable environmental conditions, especially when Pyropia suffers from other diseases. A regular acid wash of the Pyropia cultivation nets is the most common treatment for all of the above mentioned diseases, and represents approximately 30% of the total cost in Pyropia sea farming. However, the acid wash is ineffective for some diseases, especially for Olpidiopsis and bacterial diseases.
