This report presents a clinical case of trauma due to assault with a knife, and describes the importance of using the correct imaging modality in cases of facial penetrating trauma involving the superficial and deep anatomical planes. Penetrating wounds in the maxillofacial region are rare and poorly reported, but can result in serious complications that are difficult to resolve and may compromise the patient's quality of life, especially when large blood vessels or other vital structures are involved. Thus, it is essential to determine the extent of the affected blood vessels and the proximity of the retained object to the anatomical structures. In this case, digital subtraction angiography was the imaging modality chosen. The use of appropriate imaging examinations allows a proper map of the surgical field, reducing the chances of vascular damage during the surgical procedure.

Lee Je Ma (1837~1900) wrote the DongEuSuSeBoWon in 1894. Constitutional Medicine what is called Sasang Medicine has originated from him. In this book he refers to mild, serious, intractable, incurable and fatal disease. In the sight of his Medical theory each state of disease deserves to be researched. 1. In the case of Soumin exhaustion of Yang, Taeyang-Kwolum, noxious Yin, Yang is kept in the exterior by excessive Yin in the interior, middle diabetes and swelling belong to intractable disease and solid mass in the right epigastric zone belongs to fatal disease. 2. In the case of Soyangin exhaustion of Yin, lower diabetes, afternoon fever due to deficiency of Yin, spitting blood and swelling belong to intractable disease and distention of abdomen with gas or fluid belongs to fatal disease. 3. In the case of Taeumin syncope due to chills, dryness-heat, diabetes, pain of chest and abdomen and swelling belong to intractable disease and apoplexy with dosed eyes belongs to fatal disease. 4. In the case of Taeyangin vertebral disease makes flaccidity of lower limbs and dysphagia with vomiting of frothy fluid belongs to fatal disease.

This is case report of true class III malocclusion with macroglossia is corrected by glossectomy in 13 years female patient. After orthodontic treatment, the patient is bound to glossectomy because the corrected condition is relapsed to the previous condition due to relatively enlarged tongue compared with the original dental arch. By the interpretation of the cephalogram and model analysis, it is approved that the growth pattern and direction are normal range and mandible is located anterioly to the cranium. The results are follows: 1. We could treat the true Cl III malocclusion. 2. We could prevent the relapse of the treated condition by the surgical intervention, such as partial glossectomy. 3. Sensory, speech, swallowing and so other functions after the operation have been with in normal limit without any serious complications or seguellae.

Fire accident in tunnel is one of the most critical railway accidents, together with overturning of train by derailment and train crash. Tunnel structures contribute to minimize the cost and time of transport, but in case of railway fire accident occurring bring serious damages of human life caused by narrowness of shelter, poisonous smoke and high temperature raised at the inside of tunnel. For that reason, at the beginning of plan of tunnel, the optimum design for rescue of passengers is needed. For the detail and most suitable design for rescue of passengers, many tunnel designer substituted simulation program for mock examination by its high cost and effort. In this study, simulation program techniques, such as Fluent and Simulex, are applied for verifying the rescue design of passengers reduced the risk when fire accident occurred at tunnel utilizing of case study for planned railway tunnels shows 1,245m length in Iksan-Sili area.

Recently, as demands of new railway and the relocation of existing line, a number of tunnel structures have been constructed. Tunnel structures contribute to minimize the cost and time of transport, but in case of railway fire accident bring serious damages of human life caused by narrowness of shelter, smoke and high temperature, difficulty in rescue. For that reason, at the beginning of plan of tunnel, the optimum design of safety facility in tunnel for minimizing the risks and satisfying the safety standard is needed. In this study, QRA(Quantitative Risk Analysis) technique is applied to design of railway tunnel for assuring the safety function and estimating the risk of safety. The case study is carried out to verify the QRA technique for railway tunnels in Iksan-Sili.

Esophageal hiatal hernia is common disorder in western sociey, and mainly affects mid-aged women, There are two types of hiatal gernia; common and more benign type is sliding [type I], and more severe type is paraesophageal [type II], and Skinner subdivided type II as true II, IIA, III, and paraesophageal group, As Skinner`s nomination, this case could be belong to IIA, which imply the state that natural hiatus is occupied with gastric antrum or duodenum instead of normal esophago-gastric junction, Main problem of paraesophageal hernia comes from its complication; intestinal obstruction, volvulus, strangulation, and incarceration, as well as pulmonary aspiration. So, as soon as confirm diagnosis, it should be corrected surgically to prevent above complications, and sometimes it could result in serious condition. We have experienced paraesophageal hiatal hernia in 3-day newborn infant and have repaired it successfully. We used transabdominal approach to repair and to prevent reflux Nissen`s fundoplication was performed. We would report that with reference study.

A review of accidents involving farm machinery, which occurred in Korea during 2002, shows that $90.7\%$ of farm-work accidents and $9.3\%$ of traffic accidents were linked to agricultural machinery. The frequency of accidents per annum amounts to 72.2 out of 10,000 vehicles, $94.4\%$ of which relates to tillers and tractors. An analysis of the causes of the accidents revealed that $49.1\%$ of farm-work accidents were due to the tiller driver's fault or error. In the case of traffic accidents, $83\%$ of farm machinery mishaps were found to be due to violation of traffic regulations while $60.4\%$ of the farm machinery damage resulted from faulty driving or lack of safe driving practices. The average casualty count of farm machinery-related accidents is 1.39 persons per case, which consist of 0.07 deaths, 0.74 serious injuries, and 0.58 slight injuries.

The more feeding distance of substation is long and travel vehicle increases in feeding section, power supply leaches the limits. And if it exceeds the limit, it causes a serious trouble for train operation. Therefore, it is designed that the number of train increases constantly until 2030. So consistent power supply according to the increasement of vehicle in power system at present Seoul-Pusan high speed railway, regular operation in case of extended feeding occurring accidents in substation, and the least headway scheduled at relevant section and the effects installing compensation facility in case of impossible extended feeding is examined.

Tracheal stenosis induced from the various causes has still remained as a serious problem in the otolaryngologic field. There has been used the numerous methods in the treatment of the tracheal stenosis and the each case has required the therapeutic modality. Now, we report two cases of tracheal stenosis ; one case had been used the silicone T - tube in the tracheal stenosis after tracheostomy in 6 year - old child and the other one had been used the silicone tube stent with oral mucosa graft in the treatment of the tracheal narrowing due to inflammatory mass in 19 year - old male patient.

Composite materials were used widely due to merit of light weight, low maintenance cost and easy installation. But it is the cause of enormous casualties to men and properties because of weak about the fire. Particularly, it is more serious in case of subway train installed composite materials. For this reason, experimental comparison has been done fur measuring heat release rate(H.R.R) and smoke production rate(S.P.R) of interior panels of electric motor car using cone calorimeter. A high radiative heat flux of 50kW/㎡ was used to bum out all materials and to simulate the condition of fully developed fire case in the tests. It was observed that Heat Release Rate and Smoke Production Rate curves were dependent on the kinds of the interior materials. From the heat release rate curves, the sustained ignition time, peak heat release rate and total heat release rate were deduced, These data are useful in classifying the materials by calculating two parameters describing the possibility to flashover.
