This study was designed to evaluate the age, gender, location of trauma, etiology, injury site, types of treatment, elapsed time after trauma, and arrival time of children who visited trauma center of Wonju Severance Christian Hospital. Records of a total of 841 patients who were 0 - 15 years old and received care in the period from March 2011 to October 2015 at the Trauma Center, Wonju Severance Christian Hospital were analyzed. This study showed that traumatic dental injuries were more common in boys and patients between 0 - 3 years old. Under 6 years old, fall was the most common etiology and home was the most common place of trauma. However, fall decreased, and sports and etc increased largely in etiologic factors over 6 years old. Besides, home decreased, and road and kindergarten school increased largely in the place of trauma. Etiology and location of trauma were statistically influenced by the age (p < 0.05). The most commonly affected injury sites were maxillary incisors and lips. The most patients visited trauma center between 18 - 24 o'clock (53.3%), and the least patients visited between 0 - 6 o'clock (4.6%). 51.5% of patients visited the trauma center within 1 hour of sustaining trauma, and 26.8% and 11.5% of patients visited between 1 - 2 hours and 2 - 3 hours respectively. The most common treatment of traumatic dental injuries was observation, and the second most common treatment was suture. Traumatic dental injuries in children exhibit specific epidemiological features according to children's gender, age, and other conditions. These result from combination of social, developmental, and physiologic factors.

The purpose of this study was to demonstrate the effect on the degree of fatigue and accuracy of cardiopulmonary resuscitation according to the different time delays (3 minutes, 4 minutes). Carrying out repeated measures of variance (repeated ANOVA), we have shown that time effect (F = 7.835, p <.01) and group effect (F = 8.695, p<.01) and the interaction effect between time and group (F = 12.582, p<.001) were all statistically significant. It means, in the test of the main effect of group and time (3 minutes, 4 minutes) using the Bonferroni method, it turned out that the amount of lactic acid of the experimental group was larger than that of the control group (p<.01), and there was no difference until 3 minutes, but the difference of the amount of lactic acid was shown between before the experiment and after 4 minutes, and between 3 minutes and 4 minutes (p <.05), respectively. Then, in the result of the corresponding sample t-test, for comparing the according to the measurement time, the accuracy after 3 minutes became higher than the case of 4 minutes (t = 4.584, p <.001). Therefore, before 119 arrives performing cardiopulmonary resuscitation for emergency, rescuers need to perform cardiopulmonary resuscitation alternating with others before 3 minutes.

Drones, which show strong growth in the fourth industry, are commonly used for disaster response. In the event of an actual disaster, local governments should carry out 13 cooperative functions to respond to the disaster, but there are difficulties in collecting on-site information in places where it is difficult for people to access or grasp the situation. Based on the 13 collaborative functions that are essential for operations in the event of a disaster, a utilization plan of highly utilized drones was derived. Through the analysis of overseas cases and drone utilization by each department, a total of 10 out of 13 collaborative functions of the Disaster and Safety Countermeasures Headquarters (disaster situation management, emergency life safety support, emergency recovery, disaster resource support, traffic measures, medical and quarantine services, disaster site environment maintenance, social order maintenance, search, rescue, and emergency) were derived. These results can enhance the efficiency of the disaster response by presenting a plan to utilize drone images for each function.

Purpose: The aging of society has rapidly progressed, especially in Korea. Therefore, the necessity of research on end-of-life (EOL) care in elderly patients has increased. However, there are few studies on EOL care intensity for non-cancer patients. This study was designed to compare the EOL care intensity between cancer and non-cancer patients. Methods: We retrospectively analyzed the EOL care intensity based on medical records of decedents of Kyung Hee University Medical Center, a tertiary referral hospital from December 2014 through March 2015. And we compared EOL care intensity between cancer patients and non-cancer patients using statistical analysis of the frequency of invasive procedures and logistic regression analysis for factors that affect the EOL care intensity. Results: Statistical analysis showed invasive procedures, such as intensive care unit admission, endotracheal intubation followed by mechanical ventilation and emergency dialysis, were performed more frequently in non-cancer patients than cancer patients (29.3% vs. 72.4%, P<0.001). And age (P=0.038) and morbidity of cancer (P<0.001) influenced the invasive procedural decision when analyzed by logistic regression analysis. Conclusion: The EOL care was more intensive in non-cancer patients, and age and morbidity of cancer were major factors for the treatment intensity.

Self-injurious behavior is often showed in mental retardation, especially in autism. Self-injurious behavior has been regarded as a symptom cluster rather than a disease but it is an emergent clinical situation that can directly affect mortality. This case is about a refractory autistic patient who showed a self-injurious behavior of hitting the head repetitively. He was hospitalized and was treated by pharmacotherapy and behavior therapy and for this reason this clinical experience is reported with literature review. The patient is a 7-year old boy who was ward admitted from 1999 April 20 till July 10 into OO hospital OO ward because of self-injurious behavior. During the 12 weeks he had admission treatment. As for the pharmacotherapy, haloperidol was dosed up from 0.5mg to 1.0mg from the 4th week and combination drug therapy was done during the admission with naltrexone 25-50mg. As for the behavioral therapy, Differential Reinforcement of Other behavior was used and regular play therapy was done. To remove the physical restraint, headgear and hard sleeve was used. Currently, OPD follow up treatment is being done and haloperidol 0.5mg and naltrexone 50mg is maintained. The patient’s mother is educated and play therapy is done an hour daily at home. When the patient was released form the hospital, self-injurious behavior was decreased more than the moderate state and remission state is still being maintained at the outpatient clinic.

Actual vegetation map drown with the scale 1 to 100 and Alnus japonica population in Ja-neup and Woong-neup of the Mujechi moor were described in order to monitor long-termly and preserve permanently, where is a very rare Molinietea moor and a legally protected area. A total of 3036 plots of 5m $\times$ 5m were surveyed during summer 1996. Thiessen polygons of 1491 alder trees were derived from the plot data. Actual vegetation map was illustrated by 6 cover types such as needle spike-rush type, moor-grass type, alder-moor type, eulalia type, oak forest type, and exposed site. Molinia grasses native to the moor and Miscanthus grasses alien to the moor are reciprocally dominant. The area of Molinia grasslands was rapidly in decline and alder population size was dramatically in increase in the moor, particularly in Woong-neup. In Molinietea moor preservation more attention should be focused on the regulation of a nutrient rich soil from forest road and fire.

Construction of urban emergency shelters based on disaster-prevention green space is an important part of an urban disaster response plan. The accessibility of disaster-prevention green space is directly related to the disaster prevention service effect of green space. Taking the Jung-gu and Nam-gu districts of Ulsan city as research targets, the accessibility of three green spaces was analyzed by a network analysis method based on information regarding the distribution of population and green space and the urban road network. Two indicators for evaluating the service effect of green spaces were service population rate and service area rate. The results showed that the accessibility of the emergency refuge parks (5min) and central refuge parks was relatively good but the service area rate and service population rate of the emergency refuge parks (3min) and temporary refuge parks was less than 60%. In view of the overall situation, the service effect of disaster-prevention green space is at this point only general in Ulsan and there is great room for improvement.
