우리나라에서 2014년부터 2016년까지 중부지방을 중심으로 지속된 강우부족은 용수공급에 피해를 발생시키는 주요 원인이 되었다. 2014년부터 2016년까지 보령 기상관측소의 연강수량은 각각 1,010.6 m, 782.5 mm, 792.8 mm였으며 이는 보령 기상관측소 연강수량의 평년값인 1,244.3 mm의 81.2 %, 62.9 %, 63.7 %에 해당하는 양이었다. 이러한 강우부족으로 인하여 충청남도 서북부권에 용수공급을 담당하고 있는 보령댐의 저수율이 20 % 미만으로 감소하는 문제가 발생하였다(2015년 11월 6일 기준). 국토교통부는 보령댐의 저수율 감소가 지속될 경우 보령댐 용수공급 지역에 피해가 발생할 것으로 판단하였고 이러한 피해를 저감시키는 방안으로 금강 백제보 하류의 물을 보령댐 상류로 공급하기 위한 긴급용수공급 시설인 보령댐 도수로를 설치하였다. 보령댐 도수로 운영 시 지형 및 수질 문제를 해결하기 위하여 가압시설, 정수시설과 같은 부대시설이 함께 설치되었다. 이로 인해 도수로 운영 시 부대시설의 운영비용이 소요되므로 보령댐 도수로는 운영일수를 최소화하고 보령댐의 용수공급은 최대화하는 도수로의 운영방안이 필요하다. 본 연구에서는 보령댐 도수로의 효율적인 운영방안을 모색하기 위하여 다양한 보령댐 도수로 운영방안을 설정하고 각 운영방안 따른 저수지 모의운영을 실시하여 보령댐 도수로의 운영효과를 분석하고자 하였다. 도수로의 운영방안은 보령댐 유역의 유역평균강수량을 활용하여 산정한 SPI, 보령댐 실측유입량을 활용하여 산정한 월 평균유입량, 용수공급 조정기준의 단계별 저수량 등을 활용하여 설정하였다. 또한 저수지 모의운영 결과를 평가하기 위한 지표로 용도별 용수공급 신뢰도와 용수공급 조정기준의 각 단계별 도달일수, 도수로 운영일수, 무효방류량 등을 산정하고 그 결과를 비교 분석하였다.

Analyzing EU trade laws and institutional systems, the trade policy of EU has been founded, undoubtedly, on common interests for EU members. EU trade policy leaves room for 'Collective Protectionism' by permitting legal persona or interesting group to raise anti-dumping procedures. The anti-dumping policy of EU has shown a protectionism itself and has been affected by political motives. Investigation against anti-dumping can easily open and also there exists a wide range of political involvements. Furthermore, anti-dumping policy could be misused for protecting declining industries, which lost comparative advantage in global market. Economic theories show that anti-dumping measures divert import from outsider into insider members, which finally results in increasing intra-production of EU. This is exactly the reason why the anti-dumping policy has become attractive trade policy.

Gangneung Danoje does not only have the longest history but also is the largest folk festival in Korea. However, during its long history Gangneung Danoje has not always been the way as it is today. As records reveal, since the Chosun dynasty and through Japanese rule, it has gone through numerous variations and registration processes in order to become a national designated major intangible cultural asset. Especially after it has been appointed as a national major intangible cultural asset Gangneung Danoje has under gone through variety of transformations. First of the few changes is the citizen-lead characteristic. As Gangneung Cultulral Center took charge of Danoje this trait has become prominent. Hereby Chosun dynasty's government lead system has transformed into a civilian lead festival. Second alteration is the enormous scale of expansion and the variations of the characteristic of the festival because of it. Dano event has increased annually from 12 events in 1974 to 58 events by 1999. As the scale of Danoje enlarged the promoters found solutions by providing diversified events in order to satisfy peoples' various aspirations from the festival. However this solution lead to a diversion - from participating festival to a spectating festival. And the last change that occurred is the awareness of the need to develop Danoje into an international festival. This is rather a desire from the government than of the people. In 1994, Korea visiting year as an opportunity this consciousness grew active. For instance, the invitation of mass foreign folk performance in 1999 seems to conform to this policy. The intention to make Gangneung Danoje not only to represent Gangneung but also to represent Korea's folk event can be witnessed. As we enter 21st Century this inclination for international festival has strengthened. Gangneung government has shown enthusiasm to find the future of Danoje by inviting external service corps to assess Danoje. The current inclination appears to be increase its value as an international festival through UNESCO cultural property registration and having this as a foundation make Danoje become an international cultural tourist product. The judgment of this will be made after Gangneung International Folklore Festival 2004.

The rectum is the least frequently injured organ in trauma, with an incidence of about 1% to 3% in trauma cases involving civilians. Most rectal injuries are caused by gunshot wounds, blunt force trauma, and stab wounds. A 46-year-old male patient was crushed between two vehicles while he was working. He was hemodynamically unstable, and the Focused Assessment with Sonography for Trauma showed hemoperitoneum and hemoretroperitoneum; therefore, damage control surgery with pelvic packing was performed. A subsequent whole-body computed tomography scan showed a displaced pelvic bone and sacrum fracture. There was evidence of an anorectal full-thickness laceration and urethral laceration. In second-look surgery performed 48 hours later, the pelvis was stabilized with external fixators, and it was decided to proceed with loop sigmoid colostomy. A tractioned rectal probe with an internal balloon was positioned in order to approach the flaps of the rectal wall laceration. On postoperative day 13, a radiological examination with endoluminal contrast injected from the stoma after removal of the balloon was performed and showed no evidence of extraluminal leak. Rectosigmoidoscopy, rectal manometry, anal sphincter electromyography, and trans-stomic transit examinations showed normal findings, indicating that it was appropriate to proceed with the closure of the colostomy. The postoperative course was uneventful. The optimal management for extraperitoneal penetrating rectal injuries continues to evolve. Primary repair with fecal diversion is the mainstay of treatment, and a conservative approach to rectal lacerations with an internal balloon in a rectal probe could provide a possibility for healing with a lower risk of complications.

The third opium war may have already started, not only due to illicit opioid trafficking from the Golden Crescent and Golden Triangle on the international front but also through indiscriminate opioid prescription and opioid diversion at home. Opioid use disorder (OUD), among unintentional injuries, has become one of the top 4 causes of death in the United States (U.S.). An OUD is defined as a problematic pattern of opioid use resulting in clinically significant impairment or distress, consisting of 2 or more of 11 problems within 1 year, as described by the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition. Observation of aberrant behaviors of OUD is also helpful for overworked clinicians. For the prevention of OUD, the Opioid Risk Tool and the Current Opioid Misuse Measure are appropriate screening tests before and during opioid administration, respectively. Treatment of OUD consists of 3 opioid-based U.S. Food and Drug Administration-approved medications, including methadone, buprenorphine, and naltrexone, and non-opioid-based symptomatic medications for reducing opioid withdrawal syndromes, such as α₂ agonists, β-blockers, antidiarrheals, antiemetics, non-steroidal anti-inflammatory drugs, and benzodiazepines. There are at least 6 recommendable guidelines and essential terms related to OUD. Opioid stewardship programs are now critical to promoting appropriate use of opioid medications, improving patient outcomes, and reducing misuse of opioids, influenced by the successful implementation of antimicrobial stewardship programs. Despite the lack of previous motivation, now is the critical time for trying to reduce the risk of OUD.

A dynamic triaxial discrete element numerical model of lightweight soil was established using the discrete element method to study the microscopic mechanism of expanded polystyrene (EPS) particles in the soil under cyclic loading. The microscopic parameters of the discrete element model of the lightweight soil were calibrated depending on the dynamic triaxial test hysteresis curves. Based on the calibration results, the effects of the EPS particles volume ratio and amplitude on the contact force, displacement field, and velocity field of the lightweight soil under different accumulated strains were studied. The results showed that the hysteresis curves of lightweight soil exhibit nonlinearity, hysteresis, and strain accumulation. The strain accumulated in remolded soil is mainly tensile strain, and that in lightweight soil is mainly compressive strain. As the volume ratio of EPS particles increased, the contact force first increased and then decreased, and the displacement and velocity of the particles increased accordingly. With an increase in amplitude, the dynamic stress of the particle system increased, and the accumulation rate of the dynamic strain of the samples also increased. At 5% compressive strain, the contact force of the particles changed significantly and the number of particles deflected in the direction of velocity also increased considerably. These results indicated that the cemented structure of the lightweight soil began to fail at a compressive strain of 5%. Thus, a compressive strain of 5% is more reasonable than the dynamic strength failure standard of lightweight soil.

The Imjin and North Han River are sharing watershed between South and North Korea. In Imjin river basin, the April 5th dam and Hwanggang dam which are already constructed or on constrution, causes problems in water supply in the downstrean area. At the same time, in the North Han River basin, the Imnam dam is being operated for diversion to Anbyeon Youngman Hydropower Plant and it gives rise to conflict between South and North by reducing streamflow in the North Han River of South Korean side. Therefore, a cooperative framework needs to be built for settling the pending issues. In this study, based on the theory of conflict resolution in the international shared river basin, the practical alternatives are suggested. These approaches are expected to help in preparing reasonable resolution ahead of seeking political decision. Also, in order to preparing consistent and reasonable river management measures, the South-North shared river management commission was suggested.

Background: The purpose of this study was to analyze the demand and supply status of patient beds by type of medical institution, categorized into 70 clinical privilege, in order to understand the regional bed supply situation. Methods: Utilizing the 70 clinical privilege defined by the Ministry of Health and Welfare, we calculated bed demand and supply quantities from 2019 to 2021 using data from Statistics Korea and the Health Insurance Statistical Yearbook. The bed demand calculation formula was based on the detailed guidelines for the medical sector by the Korea Development Institute and the 3rd edition of bed supply basic policies announced by the Ministry of Health and Welfare. Additionally, to mitigate distorted bed supply situations caused by factors such as regional levels and patient outflows, we classified bed supply types using the population decrease index indicator published by the Ministry of Public Administration and Security. Results: Among the 70 clinical privilege, it was analyzed that a relatively balanced bed supply situation exists overall, irrespective of the type of healthcare institution. However, in medical institutions at or above the level of hospitals, regions with bed supply ratios exceeding 20% compared to demand, particularly in institutions at or above the level of general hospitals, showed a relatively high rate of demand diversion. Conclusion: We have identified the bed supply types in the 70 clinical privilege in South Korea. Based on the results of this study, we emphasize the need for bed supply policies that consider regional characteristics. It is expected that this research can serve as fundamental data for future efforts aimed at managing or rectifying bed supply imbalances on a regional basis.

Because of the various patterns of deep-water inrush and complicated mechanisms, accurately predicting mine water inflows is always a difficult problem for coal mine geologists. In study presented in this paper, the water inrush channels were divided into four basic water diversion structures: aquifer, rock fracture zone, fracture zone and goaf. The fluid flow characteristics in each water-conducting structure were investigated by laboratory tests, and multistructure and multisystem coupling flow analysis models of different water-conducting structures were established to describe the entire water inrush process. Based on the research of the water inrush flow paths, the analysis model of different water inrush space structures was established and applied to the prediction of mine water inrush inflow. The results prove that the conduction sequence of different water-conducting structures and the changing rule of permeability caused by stress changes before and after the peak have important influences on the characteristics of mine water-gushing. Influenced by the differences in geological structure and combined with rock mass RQD and fault conductivity characteristics and other mine exploration data, the prediction of mine water inflow can be realized accurately. Taking the water transmitting path in the multistructure as the research object of water inrush, breaking through the limitation of traditional stratigraphic structure division, the prediction of water inflow and the estimation of potentially flooded area was realized, and water bursting intensity was predicted. It is of great significance in making reasonable emergency plans.
