The purpose of this study is to investigate the effect of high quality CPR using the 4 types of rescue device equipment and chest compressions energy measurement in pre-hospital settings. So, we used the mode to insert load cell in ALS Skill master Manikin to develop CFMM(Compression Force Measurement Manikin) on main stretcher, CPR board, long spine board, scoop stretcher and floor. And, our research team could know that the main stretcher needed average force of 32.55 (${\pm}1.01$) kg, CPR board of 27.23 (${\pm}1.08$) kg, long spine board of 27.13 (${\pm}1.18$) kg, Scoop Stretcher of 27.38 (${\pm}1.05$) kg and Floor of 27.24 (${\pm}0.93$) kg. CPR board must be necessary in the case of CPR on main stretcher in a moving ambulance. But if the condition of patient's back surface is the removable stretcher and the long spine plate, the patient doesn't have to be spent time to use a CPR board. Furthermore, this research suggests to consider that how to take advantage of the education to students for the equipment to check in real time the energy(kg) requirement of chest compressions.

선진국에서는 1980년대부터 MVNO가 도입되었고 우리나라 학계에서도 2000년대 초반 이미 도입 필요성이 제기되었다. 그런데 2000년대 후반 통신비 인하가 주요 정책이슈로 등장하면서 이동통신사업이 개시된지 27년만인 2011년이 되어서야 MVNO가 도입되게 되었다. 2015년 4월에는 MVNO의 가입자수가 504만명으로 이동통신시장 점유율이 9%에 이르고 있으나 아직 많은 문제점을 노출하고 있다. 급속한 성장의 이면에는 저렴한 통신서비스를 바라는 소비자들의 욕구와 때늦은 MVNO의 도입이 자리하고 있다. 그리고 이통사들은 우월적 지위를 누리고 있는 한편 자회사를 앞세워 알뜰폰시장의 확보에 나서고 있어 중소기업의 입지를 약화시키고 있다. 정부의 적절한 개입이 지속되어야 할 필요가 상존하고 있다. 정부당국은 세계적인 MVNO 흐름을 조기에 인식하고 신속하게 도입할 필요가 있었으며 향후 이통시장의 경쟁환경조성에도 충분한 노력을 기울여야 할 것이다.

Objectives : This report describes the diagnostic and therapeutic procedures of Collaborative Practice between Korean Traditional Medicine and Western Medicine for two dementia patients. Furthermore, through these cases, we suggest a model of collaborative practice between Korean traditional medicine and western medicine for the treatment of dementia. Methods : Two patients suffering from several symptoms related to dementia received collaborative practice between Korean traditional medicine and western medicine. Physicians of deparment which paient first visit interviewed patient and patient's guardians, discussed the symptoms and the status of the patient. Since then, the medical team made a differential diagnosis based on the results of brain imaging, hematology, urine test. and apprehended the status of dementia by the neuropsychological test. Korean traditional physicians examined the physical symptoms and identified the pattern of dementia in Korean traditional medicine. Following this, they decided on the method of acupuncture, moxibustion, cupping and herbal treatment. Western physicians decided on the type of medication after consideration of the patient's other medical conditions. Every intervention was decided by both Korean traditional physicians and western physicians after discussion. The medical team provided education on dementia and counseled the guardians. They also wrote the paper for using the long-term care insurance for the aged. Results : Two patients showed no improvement on the neuropsychologic and activity of daily living tests. However, the patients' subjective physical symptoms were improved. The collaborative practice between Korean traditional medicine and western medicine improved the patients' and guardians' satisfaction. Conclusions : Through these cases, we propose a model of collaborative practice between Korean traditional medicine and western medicine for dementia categorized diagnosis-test, treatment, prevention, management. More specifically, we supplement qigong and psychotherapy which was inadequate in these cases.

Electroencephalography (EEG) is frequently used to assist the diagnosis of brain death. However, to date there have been no guidelines in terms of EEG criteria for determining brain death in Korea, despite EEG being mandatory. The purpose of this review is to provide an update on the evidence and controversies with regarding to the utilization of EEG for determining brain death and to serve as a cornerstone for the development of future guidelines. To determine brain death, electrocerebral inactivity (ECI) should be demonstrated on EEG at a sensitivity of $2{\mu}V/mm$ using double-distance electrodes spaced 10 centimeters or more apart from each other for at least 30 minutes, with intense somatosensory or audiovisual stimuli. ECI should be also verified by checking the integrity of the system. Additional monitoring is needed if extracerebral potentials cannot be eliminated. Interpreting EEG at high sensitivities, which is required for the diagnosis of brain death, can pose a diagnostic challenge. Furthermore, EEG is affected by physiologic variables and drugs. However, no consensus exists as to the minimal requirements for blood pressure, oxygen saturation, and body temperature during the EEG recording itself, the minimal time for observation after the brain injury or rewarming from hypothermia, and how to determine brain death when the findings of ECI is equivocal. Therefore, there is a strong need to establish detailed guidelines for performing EEG to determine brain death.

The water circulation in agricultural watersheds changes with the operation of agricultural reservoirs, it is necessary to classify and evaluate them into upstream, agricultural reservoirs, irrigation districts, and downstream. Therefore, in this study, we developed the agricultural water circulation rate (AWCR) considering an agricultural reservoir and irrigation district by improving the water circulation rate of the Water environmental conservation Act. we applied it to Jinwi watershed using the module-based hydrologic analysis system to simulate the water circulation for agricultural reservoirs and irrigation areas. The model performance during the validation period was NSE of 0.762 for the downstream stream and 0.682 for the reservoir level. And the hydrograph separation model was applied to separate the direct and baseflow. As a result of this study, The AWCR of Jinwi watershed was 71.8% on average, which was higher than the water circulation rate estimated by the downstream hydrograph separation.

Clinical trials of drugs on humans is the final and most important stage in evaluating the safety and efficacy of the drugs. Good Clinical Practice(GCP) standards were announced in 1987 to protect testees' rights as well as to ensure validity of the clinical trial results, but its implementation has been delayed until now. The purpose of this study is to evaluate the preparedness of the designated institutions to abide by GCP standards during clinical trials, and thereby to determine GCP implementability at the institutions. Survey on the status of clinical trials was conducted for the designated 83 clinical trial hospitals. Response rate was 95.2%. Donabedian's quality assessment model was applied as the basic framework for the study. And the relative - weights for the evaluation items were determined by expert's evaluation. Among the designated 83 hospitals, 39 conducted clinical trials to obtain drug manufacturing approval from 1990 to 1994. Only 19 institutions are found to be able to meet the requirements of KGCP. Structure variables - manpower, organization, and facility -, which are the basic elements for GCP, are evaluated as unsatisfied in many hospitals. Institutions which established IRB accounted for 41 or 51.9%, but those who have a protocol evaluation guideline, or Adverse Drug Reaction(ADR) reporting system were only 12 and 21 institutions, respectively. Also, the institutions providing educational programs on conducting clinical trials are few - 20. The study results indicates that the level of conducting KGCP is unsatisfactory. However, more institutions are expected to be able to meet the standards soon because GCP standards does not require so much regulation on facilities, but stress importance on research methodology and human right. At present as the institutions for clinical trials are primarily training hospitals with residency programs, such efforts as education will accelerate the implementability of GCP in Korea. Institutions must build the appropriate infrastructure and government must prepare to strongly enforce KGCP before it can successfully take place.

In recent years, the scale of damage from disasters such as earthquakes and large-scale fires and floods that are occurring in Korea is increasing. Accordingly, interest in urban disaster prevention that combines living infrastructure such as roads and parks is boosting, and it is urgent to prepare measures to reduce the damage scale of local cities. The purpose of this study is to derive implications for disaster prevention measures in areas where disaster prevention safety of local cities is weak through examples of disaster prevention safety of local cities in case of disaster. To this end, this study analyzed the regional characteristics, current status, and disaster prevention problems of regional cities in Japan, and selected disaster-vulnerable areas, and considered the distance relationship between disaster prevention bases through road network analysis. In addition, road closure simulation using ArcGIS Network Analyst was conducted to analyze disaster prevention safety in the area. As a result, the situation of the village which has a high possibility of isolation by natural disasters was grasped in advance. Through this, the suburbs confirmed the necessity of supplementing the disaster prevention function through transportation maintenance such as forest roads, and it was found that the city needs to prepare a risk management system. Furthermore, this study suggests the need for research on areas with a high possibility of isolation, especially in areas where disaster prevention functions are weak in local cities in case of disaster, and shows countermeasures for disaster prevention measures and resident education.

Rock is a heterogeneous material, which introduces complexity in the analysis of rock slopes, since both the existing discontinuities within the rock mass and the intact rock contribute to the degradation of strength. Rock failure is often catastrophic due to the brittle nature of the material, involving the sliding along structural planes and the fracturing of rock bridge. This paper proposes an advanced discretization method of rock mass based on block theory. An in-house software, GeoSMA-3D, has been developed to generate the discrete fracture network (DFN) model, considering both measured and artificial joints. Measured joints are obtained from the photogrammetry analysis on the excavation face. Statistical tools then facilitate to derive artificial joints within the rock mass. Key blocks are searched to provide guidance on potential reinforcement measures. The discretized blocky system is subsequently implemented into a discontinuous deformation analysis (DDA) code. Strength reduction technique is employed to analyze the stability of the slope, where the factor of safety can be obtained once excessive deformation of slope profile is observed. The combined analysis approach also provides the failure mode, which can be used to guide the choice of strengthening strategy if needed. Finally, an illustrated example is presented for the analysis of a rock slope of 20 m height inclined at $60^{\circ}$ using combined GeoSMA-3D and DDA calculation.

Background: Health disparities exist among and within countries, while developing and low income countries suffer more. The aim of this study was to quantify cancer disparities with regard to socioeconomic position (SEP) in 22 districts of Tehran, Iran. Method: According to the national cancer registry, 7599 new cancer cases were recorded within 22 districts of Tehran in 2008. Based on combined data from census and a population-based health equity study (Urban HEART), socioeconomic position (SEP) was calculated for each district. Index of disparity, absolute and relative concentration indices (ACI & RCI) were used for measuring disparities in cancer incidence. Results: The overall cancer age standardised rate (ASR) was 117.2 per 100,000 individuals (120.4 for men and 113.5 for women). Maximum ASR in both genders was seen in districts 6, 3, 1 and 2. Breast, colorectal, stomach, skin and prostate were the most common cancers. Districts with higher SEP had higher ASR (r=0.9, p<0.001). Positive ACI and RCI indicated that cancer cases accumulated in districts with high SEP. Female disparity was greater than for men in all measures. Breast, colorectal, prostate and bladder ASR ascended across SEP groups. Negative ACI and RCI in cervical and skin cancers in women indicate their aggregation in lower SEP groups. Breast cancer had the highest absolute disparities measure. Conclusion: This report provides an appropriate guide and new evidence on disparities across geographical, demographic and particular SEP groups. Higher ASR in specific districts warrants further research to investigate the background predisposing factors.
