  • Uremia was diagnosed in a slaughtered 20-month old bull. It had no special clinical signs, but many lesions associated with uremia were observed at postmortem inspection. It had a lot of ascites. Kidney, urinary bladder and ureter were enlarged, congested and hemorrhagic, and the incised section of those slightly smelled nasty. However, the precise cause of uremia in this case could not be completely identified.

  • The present automated manufacturing environment is very different when the classical statiscal process control method based on batch processing were used. Therefore these must be replaced by automated statiscal process control method. In this point of view , this study intends to develop the automated statiscal process control method which can be implemented in the proesent automated manufacturing environment . Specially this study suggested modified control limit line and developed the rule to identify the special cause of the manufacturing process in the aspect of the ppm manegement.

  • Foreign holies in the upper aerodigestive tract are an important cause of morbity and mortality in older adults and children under 3 years of age. Fish and chicken bones are the usual foreign bodies lodged in the hypopharynx, and most of them lodge In the lower pole of a tonsil, at the base of the tongue, at the lateral wall of the pharynx, or in a vallecula. Recently, the authors experienced a case of aspiration pneumonia caused by chronic local inflammatory reaction of the posterior wall of the hypopharynx originated from a special foreign body.

  • Recently, urban excavations are one of most frequent geotechnical work according to construction of a high rise building and subway. These kind of excavation affect to a adjacent ground or structure and it can trigger various severe accidents. Generally, the ground is closer to the excavation site, the deformation become larger. In this study, special ground settlement case due to adjacent ground excavation is presented and a cause of deformation is examined by various geotechnical exploration, lab-testing and numerical analysis.

  • Chattering phenomenon is an abrupt relative vibration between the strip and rolls of rolling machine in working. It inevitably results from the progress of the degeneration in the mill facilities. This research was carried out in order to analyze the characteristic and find the cause of chatter mark in finishing mill and it was founded that major causes are facility character of driving part and special condition in case of excessive roll force.

  • For international projects in general and the projects in the Gulf area in Particular, the most common cause of construction disputes and claims is construction delay. This paper will present different surveys to identify the causes of delay, the parties responsible, and how delay can be avoided. This paper will outline how these factors impact damage assessment and entitlement. Furthermore, a case study will be presented to show how the responsibility and damages due to delay are assessed and how entitlements are calculated.

  • Since the 5th Five-Year Plan for the Development of Special Education in 2013, special schools have been trying to improve facility standards to advance special education support. The purpose of this study is to find out the current status of the spatial composition of facilities for public special schools that will be established and planned after 2013, and analyze the differences from the existing school spatial composition to determine the space composition ratio and details required for the establishment of special schools in the future. As a result of the analysis, the total area of facilities of special schools established after 2013 increased by an average of 1,822.1㎡ (about 16%). Through actual drawing analysis, it was confirmed that both the dedicated area and the public area had increased. The cause of the increase in the public area was confirmed to be an increase in hallway width and ramps, halls, and toilet between classrooms, and the reason for the increase in the dedicated area was that the newly installed 'Learning Support Space' had an average of 20 additional rooms installed per school.

  • Pediatrics in Geumwon(金元) age had fanned peculiar children's etiology, Byeonggihak(病機學) and Byeonjeungnon(辦證論) curative system grounded on medical theory in Geumwonsadaega(金元四大家). Yuwanso(劉完素), who was front-running man in that age, used so many times 'Yanggyeoksan(凉隔散)' or 'Bangpungtongseongsan(防風通聖散)' which have Hanryang(寒凉) disposition for curing children's disease in view of pathology in Yeoldahanso(熱多寒少), which is his special academic thought, after then Judangye(朱丹溪) succeed Yuwanso(劉完素)'s this view of pathology, Yang-eumjahyeol(養陰滋血) developed the one and made it a standing rule to cure children. Also Idongwon(李東垣) grasped that the main cause of disease is starvation because of war. As a result of it, he insisted on theory, internal cause's outbreak of person's illness, Naesangbiwi(內傷脾胃), Baekbyeong-yusaeng(百病由牛). In this view of this principle, he assorted and used following medicine 'Seungma(升麻), Siho(柴胡), Hwanggi' as 'Seungbalyanggi(升發陽氣)' method to cure children, and concentrated on children's spleen and stomach cure with this way. Jangjongjeong(張從政) applied 'Purgation therapy[攻下法]', Hantoha(汗吐下) centered on the theory of exogenous factors[外因說] , which explains that children's disease is Sagichimseup(邪氣侵襲), too. Like this, in Geumwon(金元) age, they had studied very seriously about main cause of children' s disease in two part, an internal cause and an external cause. Also, in pathological part they had approached academically 'Hwayeolchibyeong(火熱致病)' and 'Gigiseunggangsiljo(氣機乘降失調)' from diverse angles.

  • Incident investigation is one of the most important processes among various other safety management methods to prevent industrial accidents. Finding the root causes of accidents, eliminating hazards, and improving safety are the most important purposes of investigating accidents. During the investigation process, root cause analysis (RCA) techniques are used to effectively identify RCA. Over the past few decades, over 30 RCA methods have been developed. These techniques are being widely used in some industries, such as the nuclear and aircraft industries; however, most of the RCA techniques require professional knowledge and special training, making it difficult for safety managers in their respective fields to understand and apply them. Therefore, managers of general industrial sites are rarely present at the scene of actual accident investigations, and they cannot contribute much to the purpose and effectiveness of these investigations. In this study, to address these issues, we developed an RCA technique to facilitate root cause investigation of accidents in real-world industrial sites. To develop new techniques, Systematic Cause Analysis Technique (SCAT), one of the RCA techniques, was used to investigate incidents in the enterprise over three years. We also utilized feature analysis and other papers from existing RCA techniques. To verify its effectiveness, the technique proposed was also applied to the accident case. The technique developed can easily identify and analyze the root cause of an accident and help industrial managers. It can also identify the root cause category where accidents are concentrated and use this data to establish guidelines for preventing future accidents and, thus, focus on prioritizing improvement initiatives.

  • The purpose of this study was to investigate the knowledge level about ADHD in 207 of J and W universities special education students in Gyeonggi and Jeolla provinces. Data were gathered by using a survey method. To analyze data, statistical methods such as ANOVA and t-test were used. The results show the highest rate of correct answers in 'progress and treatment of ADHD' and the lowest rate of 'knowledge in the cause of ADHD'. The level of knowledge about ADHD is found to be different among the groups according to grade, major, experience with ADHD children and experience of taking related ADHD courses. On the other hand, the level of knowledge about ADHD don't differ according to gender and educational practice. Based on the results of this study, we discuss the necessity of acquiring knowledge about ADHD for pre-service special teachers and how to improve their teaching program for ADHD children.
