Objectives : The purpose of this study was to find out the characteristics of patients who admitted due to industrial accident and to promote the superiority of oriental medical treatment on the sequelae of industrial accident. Methods : We analyzed the medical charts of 51 inpatients in a local oriental medicine hospital. The patients had been hospitalized from May 1, 2003 to October 31, 2010. Results : 1. By gender, males accounted for 78.4%, while females 21.6%. By age, most incidences occurred in the forties(29.4%), fifties(23.5%) and thirties(19.6%) in order. 2. Most causes of accident was carelessness(27.5%) and fall down(21.6%) was the next. 3. With regard to the interval from occurrence of accidents to hospitalization, 20 cases(39.2%) were found to be hospitalized 31～90 days after the accidents, followed by 11 cases(21.6%) in 91～180 days and 7 cases(13.7%) in 181～360 days. 4. Most cases turned out to be injuries with 40 patients from Sequelae of intracerebral hemorrhage (23.5%) and Lumbar and other intervertebral disc disorders with radiculopathy(13.7%). The mean duration of hospitalization was $209.03{\pm}346.04$ days. Inpatients of Organic brain syndrome NOS numbered the longest stay($676{\pm}86.26$days), Sequelae of intracerebral hemorrhage recorded $541.91{\pm}541.83$ days hospitalized. 5. Most of inpatients were treated with acupuncture(100%), herbal medication(98.0%), oriental physiological therapy(82.3%), and moxibustion(76.4%). Conclusions : This article will help the researchers related to Oriental medicine establish basic source of Oriental medicine approach for inpatients due to industrial accident.

To determine the incidence rate of accidents and its associated factors, a prospective survey was carried out in a rural area of a total of 1,360 residents for 1 year from January 1 to December 31, 1988 in Shin-am Ri, Jungdong Myun, Sangju Kun, Kyungpook Province. Data for accidents were collected by the community health practitioner who is working at Primary Health Post in Shin-am Ri. A total number of accident cases was 85 among 1,360 persons during one year study period, and annual incidence rate was 62.5 per 1,000 persons. The highest incidence rate of accident was observed in the age group of 30-39 was 179.8. The incidence rate of accident in male was 86.5 which was about 2 times that in female. In male, the highest incidence rate was seen in 30-39 age group and in female, 60-69 age group. The highest incidence rate of accident was observed in spring(29.4%) and summer(29.4%), and the lowest in fall(17.7%). The highest incidence rate of accident was observed in Friday(24.5%) by day of week, and between 9 a.m. to 12 a.m. by time zone. The most frequent use of medical facilities was Primary Health Post(51.8%) and the next was clinic(38.8%). Mean duration of treatment was 9.8 days. The accident occured in the room and kitchen(23.5%), in the yard and barn(23.5%), on the road(22.4%). and in the rice field and dry field(20.0%). The causes of accident were motor vehicle accident(20.0%), piercing or cutting(20.0%), collision or fighting(12.9%), and poisoning(11.8%) in order of frequency. The most common type of injury was open wound which was 43.5%. The most common tool of accident was farm machine which was 23.5%. The most common injuried part of body was extremity(55.3%).

For the bolster type bogie, bolster anchor body connections are proviede to transmit the longitudinal loads for traction or braking between the carbody and the truck. The bolster anchor body connection is generally composed of anchor rod bracket, anchor rod and its fastening devices. The bolster anchor body connection shall be basically capable of withstanding a longitudinal load resulting from excessive braking case or impact. Additionally the north America standard requires that the anchor rod bracket shall be frangible, I.e. the anchor rod bracket shall fail and fall away under load before the carbody structure is damaged since to protect the cabody structure in the event of unexpected accident. This paper describes the shear connection design using the optimized mechanical fasteners in the bolster anchor body connection to satisfy these Northe America requirements.

Calcaneal fractures account for 2% of all fractures and approximately 60 to 70% of tarsal fractures. These fractures typically are the result of high-energy injury, such as a motor vehicle accident or a fall from a height. The potential for disabling malunion following intrarticular displaced calcaneal fracture is high, regardless of treatment. Fracture displacement typically results in loss of hindfoot height, varus and widening of the hindfoot, with possible subfibular impingement and irritation of the peroneal tendon and/or sural nerve. Frequently, subtalar joint develops posttraumatic arthritis. In symptomatic patients with calcaneal malunion, systemic evaluation is required to determine the source of pain. Nonsurgical treatment, such as activity and shoe modification, bracing, orthoses, and injection, is effective in many patients. Surgical treatment may involve simple ostectomy, subtalar arthrodesis with or without distraction, or corrective calcaneal osteotomy. A high rate of successful arthrodesis and of patient satisfaction has been reported with surgical manamgent.

The records of 25 patients with traumatic diaphragmatic injuries seen at Chosun University Hospital from February 1977 to May 1991 were reviewed. We treated 20 male and 5 female patients ranging in age from 6 to 72 years. The diaphragmatic injuries were due to blunt trauma in 19 cases[traffic accident 13, fall down 4, compression injury 2] and penetrating trauma in 6 cases[stab wound 5, gun shot 1]. Most common symptoms were dyspnea[72%], chest pain[56%] and abdominal pain [40%], Chest X-ray were normal in 7 cases[28%] and 22 cases[88%] were diagnosed or suspected as diaphragmatic injuries preoperatively. The repair of 25 cases were performed with thoracic approach in 16 cases, thoracoabdominal approach in 6 cases and abdominal approach in 3 cases. Postoperative complications included atelectasis, wound infection and empyema. there was no postoperative death.

Twenty-three patients with traumatic diaphragmatic injuries treated at the Department of Thoracic and Cardiovascular Surgery, Keimyung University Dongsan Medical Center from Aug. 1978 to Nov. 1990 were reviewed. There were 19 male and 4 female patients. The age distribution was ranged from 1.5 to 72 years, with a mean age of 34.3 years. Sixteen patients had blunt trauma[traffic accident 14, fall down 2], and 7 had penetrating injuries[stab wound 6, broken glass 1]. Sixteen [70 percent]of the injuries occurred on the left side and 7[30 percent] on the right side. Fifteen patients were operated on during the acute phase, 5 patients during the latent phase, 2 patients during the obstructive phase. The surgical approach in 20 patients was through a thoracotomy; in 2 patients, a thoracoabdominal incision was necessary, and in 1 patient, a laparotomy was performed. Herniated organs in thorax included stomach[10], colon[5], small bowel[5], spleen[4], liver[2]. Postoperative complications included wound infection, empyema, pneumonia, hepatitis and respiratory failure. There were 3 postoperative deaths, 2 with cerebral dysfunction and 1 with sepsis.

Many of the falling which is the number one risk factor in lethal accidents in construction could have been prevented if the right activity or supervising had been taken in time. All other measures do not preventive the fall, but rather intercept the fallen itself or preventive severe injury. The most common and the bets measures on the preventive measures are guardrails which are to be worn on the site. Workers always exposed the risk of serious accidents induced by causal effects related with environments around construction sites. In order to represent how to decrease the risk of workers, this study was accomplished with a number of interview with experienced site director, cheief of instructors, workers. And the questionaire survey (2012. 5~2012. 10) were used to make proposed policies which are expected to reduce critical disastrous accidents and strength authorized limits of director's management automatically.

This paper is estimation of structure damage caused by VCE(Vapor Cloud Explosion) in enclosure. As we estimate the influence of damage which occur at gas facility in factory. We can utilize it the elementary data of safety distance. In this study, the influence of explosion over-pressure caused by VCE in enclosure was calculated by using the Hopkinson's scaling law and the accident damage was estimated by applying the influence on the adjacent structure into the probit model. As a result of the damage estimation conducted by using the probit model, both the damage possibility of explosion overpressure to structures 20 meters away and that of overpressure to glass bursting 80m meters away showed nothing.

이 논문은 뇌졸중 환자를 대상으로 하여 불안정한 지지면에서의 균형 훈련이 안정 지지면에서의 균형 훈련과 비교하였을 때 균형 능력 향상에 어떠한 영향을 주는지 알아보고자 한다. 연구 대상자는 뇌졸중 환자 30명으로 안정지지면 운동군과 불안정 지지면 운동군으로 분류하여 주 3회 6주동안 실시하였다. 균형능력의 측정은 Good balance system를 사용하였다. 안정지지면 운동군에서는 속도모멘트만 감소하였고, 불안정 지지면 운동군에서는 내외측, 전후방, 속도모멘트에서 감소하여서, 안정 지지면 운동군보다 불안정 지지면 운동군에서의 운동이 균형 훈련이 좋은 것으로 나타났다. 눈을 감고 있을때는 눈을 뜨고 있을 때보다 안정 지지면과 불안정 지지면에서의 균형정도는 감소하는 것으로 나타났다. 따라서, 안정지지면에서의 균형훈련보다 불안정 지지면에서의 훈련이 더 효과가 있는 것으로 나타났다.

Several falling-sensing terminals have been developed which are able to detect the fall/upset accident of the elderly and transmit the collapsing signals to the administrative server via RF communication using 400MHz bandwidth. Supposing there might be no communication problem within a sanatorium, just single terminal without relay function had been made as a prototype in the first stage of development. However some communication problems have discovered at the coner of the floor apart from the other floor diagonally in the same building. Same kind of problems have been happened in the area behind a steel fence or a car. To solve these kinds of communication problems, we have developed several terminals and added up relay function to them. In this paper we represented that the success ratio of the communication has been improved by using relay function among several terminals.
