The study was carried out to provide basic data of improving the accessibility of medical service through identifying the factors that make hospital injury inpatient in non-residential area not in their residential area in Gyeongsangnam-do. This study analyzed not only 8,225 cases of discharged patients with damages from 2008, provided by the Korea Centers for Disease Control and Prevention, but also using a census and a research data on the actual condition from health care system. This study conducted a frequency test, a chi-square test and a logistic regression In result, first, the centralization of medical utilization of patients with damages is apparent centrally the city area. Second, medical utilization of injury patients in non-residential areas were significantly higher local area compared to City area. To improve this, a policy that can not only provide medical centers and sickbed, but also improve the quality of local medical treatments for the localization of medical treatments, for the accessibility of medical services, government is demanded policy for patients with damages in local area.

농산물은 수확된 후부터 계속해서 호흡, 증발, 대사작용을 계속한다. 이런 제반 활동에 기인된 품질손실을 수송과정에서 회복시킬 수는 없으며 단지 농산물은 자체내의 대사작용에 의해서만 에너지를 공급받아 품질을 유지해야 한다. 수확 직후부터 농산물은 세포의 부패로 인해 품질이 저하되기 시작하며 저장기간이 줄어들게 된다 결국 농산물은 수송하고 처리하는 동안의 온도변화, 수분감소, 가스발생 빈도, 물리적 손상, 위생상의 문제 등에 노출된다. (중략)

최근 풍력에너지 발전기술이 해상 풍력 및 대형 풍력으로 천이되어 감에 따라 더 향상된 신뢰성 기술을 요구하고 있고, 풍력 블레이드는 풍력발전시스템에서 고장 빈도가 비교적 낮지 않고, 고장 발생 시 심각도가 상대적으로 높아 신뢰성을 고려해야 하는 부품이다. 블레이드 제작 생산 과정과 사용 중에 발생하는 손상 및 결함은 신뢰성의 심각성에 큰 영향을 미치고 있어 본 기술에서는 블레이드에서 발생할 수 있는 결함 유형, 결함을 탐지하는 기술 그리고 신뢰성을 평가하는 시험/평가 기술에 대하여 소개하고자 한다.

후두 및 기관협착증은 선천적으로 발생하기도 하지만 대부분이 후천적으로 발생한다. 후천적인 원인으로는 외부로부터의 외상에 의하기도 하지만 대개가 기관내 삽관 후유증으로 발생하는 것으로 알려져 있다. 기관내 삽관에 의한 기도 점막의 손상은 대부분 가역적이기는 하지만 영구적으로 협착을 초래하는 경우, 그 치료에 있어서 많은 노력이 필요할 뿐만 아니라 치료 자체가 매우 까다롭고 실패 할 수도 있다. 따라서 후두 및 기관협착증의 원인을 정확히 이해하고 예방하는 것이 매우 중요하다. 이러한 관점에서 후두 및 기관협착증의 선천적, 후천적 원인들에 대해서 검토하여 보았다. 특히 기도 내 삽관에 따른 협착증이 가장 많은 빈도를 차지하는 만큼, 이의 병태생리와 발생에 관여하는 여러 인자들에 대해서 중점적으로 문헌 고찰하였다.

Recently, increasing number of urban ground subsidence occurrences has been identified. This situation is mainly due to the increased number of underground cavities. This study is intended to develop the method that prevents ground settlement caused by deteriorated or damaged sewers, which are the main cause of land subsidence. To that end, GPR exploration was conducted using CCTV monitoring of deteriorated sewer at the location with high settlement potential. Through such CCTV monitoring and GPR investigation, abnormal ground behavior was monitored at the site where sewer was damaged, joint was cracked and soil was deposited. According to site investigation in this study, evaluation method using correlation analysis of CCTV monitoring and GPR investigation results is expected to prevent ground settlement attributable to damaged sewer.

In this study, for research on an improvement of the seismic safety of an EDG system, a small scale EDG system was manufactured. For the isolation system, the Coil Spring-Viscous Damper systems were selected. For the shaking table test, 3 kinds of seismic motions were selected which had different frequency contents. In this study, the isolation effects were different and they depended on the input seismic motion. In the case of an NRC earthquake which had low fiequency contents, the isolation effects of the horizontal direction were 20%. But for the seismic motions which had high fiequency contents, the isolation effects were $50{\sim}70%$. In the case of the vertical direction, poor isolation effects were observed. It was because the design properties and the real properties of the isolation system were a little different.

This study aims to argue fundamental issues on factors associated with revenues of hand injury patients to effectively manage hospitals specialized in hand injuries. The study employes 2,461 patients who entered S hospital from 2008 to 2010 with hand injuries. The followings are the results of the study. First, there is significant difference among occurrence of hand injuries with regard to demographics of patients. That is, it is likely to have longer average length of stay(ALOS) of male over female, of the elderly over infants and toddlers, and vice versa on average daily patient revenues. Also, compared to patients with traffic and labor insurance, patients with health insurance is likely to stay longer at lower daily cost. Fifth, demographics and incidence of hand injuries were significantly associated with average length of stay(ALOS) and average daily patient revenues. That is, male over female, age over 60 over any other age categories, patients with traffic and labor insurances over one with health insurance, cases with laceration, avulsion and bone transplantation over any other types of hand injury patients were factors significantly related to ALOS and average daily patient revenues. In sum, it is needed to focus on education and campaign to raise attentions on preventing various hand injuries. Also, managers at hospitals specialized in hand injuries should pay attention on issues such as reducing ALOS to run the organization effectively.

천연가스의 수송을 위해 사용되는 가스배관에 대한 구조적 안전성을 확보하기 위해서는 전체 시스템의 파손 및 위험요소를 효과적으로 평가할 필요가 있다. 위험요소(risk)라고 하면 보통 인명피해와 같은 바람직하지 않은 사고(undesired event)가 발생할 수 있는 가능성이나 확률로써 정의가 되어지는데, 가스배관이 설치되거나 작동되어 질 때에 이러한 파손(failure)의 가능성을 매우 작게 하더라도 위험요소가 존재하게 된다. 특히, 가스배관의 경우 파손으로 인한 사고빈도는 매우 낮다고 보고되어 있지만, 일단 파손이 발생하면 인명 및 재산상의 피해가 매우 크기 때문에 파손의 원인을 분석하여 파손사고의 비율을 최소한으로 낮추는 것이 필요하다. 본 고에서는 해외 가스배관 파손사례를 통해 손상발생 원인에 대해 알아보고 지하매설배관의 위험요소를 평가하는 방법에 대해 기술한다.

저출력레이저는 인체조직에 biostimulation effects를 가지므로 구강주위에 발생하는 여려가지 질병에 대한 저출력레이저광의 효과에 관하여 많은 연구가 시도되고 있으며 또한 치료에 응용되고 있다. 감염창상에 저출력레이저 조사시 조직치유의 기전이 세균 성장에 의한 조직손상보다 주위 정상조직의 biostimulation effects가 우세하기 때문이라는 가설을 확인하고저 본 연구를 시행하였다. 백서 7마리를 레이저 조사군과 대조군으로 나누어 감염창상의 면적차이를 비교하여 다음고 같은 결론을 얻었다. 1. 저출력레이저 조사군에서 창상수축율이 현저히 높았다. 2. 부종의 빈도는 저출력레이저 조사시 뚜렷하게 감소하였다. 위의 사실로 보아 저출력레이저 조사시 감염창상의 치유촉진은 주위 정상조직의 biostimulation effect가 세균증식에 의한 조직의 손상보다 우세하기 때문이라는 가설을 확인할 수 있었다.

This study aimed to identify the efficiency of short track-related sports injury prevention program consisted of muscle strength and neuromuscular training on non-contact injury incidence and characteristics in knee and ankle joints and low back for elite short track speed skaters. Twenty-five short track athletes who belonged to G-City Team were participated in this study from Nov. 2017 to Jul. 2018. Information on their sports injuries occurred were collected and injury prevention program was applied in their warm-up every training sessions and competition. Also their symptom-level of knee and ankle joint and low back were measured by using OSTRC overuse injury questionnaire and Cumberland ankle instability(CAIT). The injury incidence rate after application of prevention program was 2.79 injuries/1,000 hour exposures(HEs), which was lower than before (3.04 injuries/1,000HEs). The OSTRC score (30.89±28.34 and 23.84±23.61, respectively) in knee and low back after application of prevention program were lower than before (58.47±26.77 and 52.36±21.55, respectively), and the CAIT score (13.47±6.07) in ankle joint after application of program was higher than before (16.26±7.28), which means that their symptom-level was alleviated with sports injury prevention program. In conclusion, the sports injury prevention program designed for short track's motion and characteristic can have positive influences on the occurrence of non-contact injury for short track speed skaters.
