Patients with cerebral palsy have higher risk of traumatic dental injuries because of clinical characteristics, such as, ataxia, large overjet and lip incompetency. Especially, intrusive luxation has rare occurrence but higher incidence of complications. It can be treated by expecting re-eruption, orthodontic reposition, and surgical reposition. Clinicians should be aware of management and follow-up in dealing with cerebral palsy patients who are exposed by intrusive luxation, due to their involuntary movement. This case report describes a 9-year-old male patient with cerebral palsy and epilepsy who experienced intrusion of maxillary permanent central incisor. After one-month follow-up, waiting for spontaneous eruption, pulp necrosis on maxillary permanent central incisor had proceeded. Therefore, surgical reposition with resin wire splint and apexification was performed under conscious sedation with midazolam. After two months, removal of resin wire splint was done. Gutta percha filling and composite resin restoration were performed after sixteen months. During five-year follow-up ankylosis and partial root resorption were observed. But there was no significant complications.

This research was carried out to elucidate the causes of fruit skin browning in 'Mansu' pear for the last 2 years. It was observed that skin browning was induced even by the small mechanical injury produced during grading and packing for the market supplies after harvest on the fruits of 'Mansu' pear. The incidences of fruit skin browning in pears treated with artificial mechanical injuries were investigated between 'Niitaka' and 'Mansu' pears. The results showed that fruits of 'Mansu' are more susceptible to skin browning than those of 'Niitaka', We also found that the epidermis of fruits in 'Mansu' pear was thinner than that of 'Niitaka', and that there was lower incidence of fruit browning in epidermis of pears with high chlorophyll content than those with low chlorophyll content. The skin browning in fruits could be considerably reduced by sorting and grading them wrapped with paper bags for the fruits of 'Mansu' pear.

Purpose: We report the surgical outcomes for femoral shaft fractures in polytrauma patients who were temporarily treated with external fixation and subsequently converted to internal fixation. Methods: From August 2008 to April 2012, we enrolled 13 patients with multiple traumas due to high-energy injuries and concurrent femoral shaft fractures in which temporary external fixation was carried out. The mean age was 39 years, with a range from 18 to 55 years. Ten were men and 3 were women. According to the AO/OTA classification of fractures, type A was found in 5 patients, type B in 6, and type C in 2, with open fractures being found in 6 patients and femoral artery rupture occurring in 2. For internal fixation, intramedullary nailing was performed in 7 patients, and minimally-invasive fixation of locking compression plates was used in 6. Results: Of the 7 patients converted to intramedullary nailing, 1 experienced delayed union. Of the 6 patients treated with minimally-invasive plate fixation, delayed union occurred in 5, and an auto-bone graft was performed within, on average, 8 months (range: 5~10 months), leading to bone union in all cases in the final follow-up. None of the patients experienced infections or complications involving other organs after having been converted to internal fixation. During the mean follow-up of 19 months, patients achieved satisfactory functional outcomes. Conclusion: In polytrauma patients with a femoral shaft fracture who have been treated with temporary external fixation and who may need internal fixation due to the occurrence of delayed union, an appropriate internal fixation method needs to be selected based on the patient's physical status, and the fracture type.

In the Oriental Western Consideration of Habitual Abortion, the result of this study is summarized as follows: 1. Habitual abortion means repetition of Tatae(abortion within 3 months), Sosan(abortion after 3 months), and Bansan(abortion after 5 months), as it agrees with Hoaltae, Sutatae and Nuing-Nuta in oriental medical science. 2. Frequency in Occurrence of habitual abortion is about 0.2-0.4%> in the whole pregnancy and the Ratio of Risk increases according to frequency and age increase. 3. Generally, the cause of habitual abortion is due to the cause of the mother. Therefore, diagnosis and treatment of before-childbirth are needed, and 'measures taken to prevent abortion' is in use to improve the condition of health of before-childbirth in oriental medical science. 4. The 50-60% of early abortion is due to the heterochromosome and the ratio of risk of habirual abortion is hightest in heterochromosome. 5. The causes of habitual abortion are summarized as vital energe and blood weakness. impairment of Chong and Ren, aflection by exopathogen, fever caused by blood deficiency. weakness of the spleen and the stomach, excess of seven emotion. excess of a sexual desire and injury of a contusion and also the treatments are summarized as invigorating qi (vital energy) and enriching the blood, reducing fever and enriching the blood, reinforcing the spleen, tonifying the Chong and Ren, the practice of a sceticism, psychological peace in oriental medical science. 6. The approch of modem oriental medical science is based on diagnosis and treatment based on 'over all analysis of symptoms and signs' of traditional oriental medical science. it goes abreast with diagnosis of western medical science, and it can be expected mare inclusive effect of treatment because 'Acupuncture for prevent abortion', 'Acupuncture with the needle warmed by burning moxa', and so on being developed except medicinal therapy.

Objectives : This study aims to evaluate current clinical evidence of acupuncture treatment for rehabilitation in patients with traffic accident in South Korea. Methods : Seven Korean databases were searched for prospective clinical trials for acupuncture on rehabilitation in patients with traffic accident from their inception to June, 2009. Only studies conducted in Korean language were searched. Risk of bias in included randomized controlled trials were assessed by Cochrane Handbook procedure. Results : Fifteen clinical trials were included among 31 studies searched. Eight were observational studies, five were non-randomizedcontrolled trials, and two were randomized controlled trials. In all of included studies, acupuncture were conducted with other concomitant treatment. Included studies dealt with such conditions as neck pain, low back pain tinnitus after traffic accident, post-traumatic stress, oculomotor nerve palsy, diplopia and insomnia. All of included studies reported favorable effects of acupuncture group compared to baseline or control group. All of included studies lacked the occurrence of adverse events. High risk of bias were observed in two randomized controlled trials. Conclusions : There is no evidence that acupuncture is effective for rehabilitation of traffic accident. All of included studies lacked appropriate methodological qualities and internal validity. Future welldesigned clinical trials that evaluate the effects and safety of acupuncture treatment for rehabilitation in patients with traffic accident is needed.

Xanthomonas arboricola pv. pruni is the causal agent of bacterial black spot disease on some stone fruits, e.g. peach, plum and apricot. To evaluate pathogenicity of Xanthomonas arboricola pv. pruni strain from plum, inoculum of the isolated strain was spray inoculated to fruits and leaves of apricot, Japanese apricot and plum. Apricot and Japanese apricot showed severe black spot symptoms on fruits and shot hole symptoms on leaves. In case of apricot, about fifty percent of fruits did not grow and dropped by hypersensitive reaction to spray infection. Plum, cv. Formosa was very susceptible, showing severe black injury lesions on fruits and cankers on leaves and new twigs. On the other hand, plum cv. Daesukjosaeng, was highly resistant. Fruits of several plum cultivars such as Formosa and Chuhee were severely infected at natural infected orchards by X. arboricola pv. pruni. Where as those of Daesukjosaeng, Taeyang, Soldam and Hongrogen were moderately infected.

Due to the rapid development of construction technology with effective land utilization in this nation, many tunnels were and are being built across the country. However, the smoke and the heat generated from tunnel fire are the most important critical factors which may results in both massive personal injury and property damage, especially, due to the closed surrounding of the tunnel. Considering this particular nature of the tunnels, this study aims to install a fire detection system using an optic fiber cable to measure the temperature changes, compare, and analyze the resulted values with the times of temperature changes of the sensor by performing fire simulations under the same condition as a real fire test. From the results, it has been found that the temperature sensor detects a fire occurrence and generates an alarm within one minute after ignition for both a real fire test and a fire simulation alike, and also that the characteristics of temperature changes of the sensor has close relations with the speeds of the currents inside the tunnel. In addition, considering the tunnel fires can affect the evacuation efficiency and the fire extinguishing activities of the fire brigade inside the tunnel, the temperature sensor must be able to search and find the locations and directions of the fires correctly.

Purpose: Various changes in nutrition, metabolism, immunity, and psychological status occur through multiple mechanisms after gastrectomy. The purpose of this study was to predict disease status after gastrectomy by analyzing diseases pattern that occur or change after gastrectomy. Materials and Methods: A retrospective cohort study was conducted using nationwide claims data. Patients with gastric cancer who underwent gastrectomy or endoscopic resection were included in the study. Eighteen target diseases were selected and categorized based on their underlying mechanism. The incidence of each target disease was compared by dividing the study sample into those who underwent gastrectomy (cases) and those who underwent endoscopic resection for early gastric cancer (controls). The cases were matched with controls using propensity score matching. Thereafter, Cox proportional hazard models were used to evaluate intergroup differences in disease incidence after gastrectomy. Results: A total of 97,634 patients who underwent gastrectomy (84,830) or endoscopic resection (12,804) were included. The incidence of cholecystitis (P<0.0001), pancreatitis (P=0.034), acute kidney injury (P=0.0083), anemia (P<0.0001), and inguinal hernia (P=0.0007) were higher after gastrectomy, while incidence of dyslipidemia (P<0.0001), vascular diseases (ischemic heart disease, stroke, and atherosclerosis; P<0.0001, P<0.0001, and P=0.0005), and Parkinson's disease (P=0.0093) were lower after gastrectomy. Conclusions: This study identifies diseases that may occur after gastrectomy in patients with gastric cancer.

Objectives: To investigate the trends of industrial injuries among long-term health care workers in Korea Methods: T7866 injuries were selected from the total industrial injuries approved by the Industrial Accident Compensation Insurance Act(Occupational Safety and Health Act) among long-term health care workers between 2007 and 2016 in Korea. We analyzied the trends of industrial injuries according to work process, occurrence type, and causes. Results: The industrial injuries among long-term health care workers increased since 2012. The mostly occurred area for industrial injuries were low back areas, which is related that the most serious industrial injuries occurred when the one long-term healthcare worker lift manually the recipient, from bed(ondol, Korean floor heating system) to a wheelchair, bed to bath bed, and wheelchair to bath chair. In addition to this, lack of workforce, increased work intensity due to overwork contributed the increasing of occupational injury. Conclusions: This study suggests that the main causes of industrial injuries were Lack of facilities and equipment for small private long-term care institutions, The physical load that goes into lifting the recipient directly, work intensity such as excessive workload and increased work speed. We suggest that the social publicization of long-term care service for the elderly, avoiding ways to lift recipients directly, introducing lifting machines as well as improving working methods, and reducing the workload of caregivers are required.

Purpose: Fractures are common in the military population, but limited studies have investigated the incidence of fractures among Korean military personnel. Hence, this study aimed to clarify this issue. Methods: Eligible subjects were patients who had sustained a fracture and were registered in the N-DEMIS (the medical records system of participating hospitals) from June 2017 to May 2019. Fractures were categorized according to the fracture site, patients' age, sex, and type of duty. Results: In total, 23,687 patients with 23,981 fractures were included. There were 216 patients with multiple fractures, of whom 156 had fractures at two sites, 42 had fractures at three sites, and 18 had fractures at four sites. Of the 23,687 patients, 23,340 were men and 347 were women. The incidence of fractures in men and women was 12.96 per 1,000 person-years and 0.19 per 1,000 person-years, respectively. In terms of the broad location of fractures, the percentage of fractures was the highest in the hand, followed by the foot and lower leg. When the location of fractures was analyzed more specifically, the percentage of fractures was the highest in the phalanx (thumb and fingers), followed by the ankle and metacarpal bones. Conclusions: Hand, foot, ankle, and wrist fractures were the most commonly encountered fractures in the Korean military population. To prevent the loss of combat power due to non-battle-related injuries, thorough preparation is necessary, including protective equipment and preliminary training for areas with a high frequency of fracture occurrence.
