The aim of this paper was to review the biomechanics of knife injuries, including those that occur during stabbing rampages. In knife stab attacks, axial force and energy were found to be 1,885 N and 69 J, respectively. The mean velocity of a stabbing motion has been reported to range from 5 to 10 m/sec, with knife motions occurring between 0.62 and 1.07 seconds. This speed appears to surpass the defensive capabilities of unarmed, ordinarily trained law enforcement officers. Therefore, it is advisable to maintain a minimum distance of more than an arm's length from an individual visibly armed with a knife. In training for knife defense, particularly in preparation for close-quarter knife attacks, this timing should be kept in mind. Self-inflicted stab wounds exhibited a higher proportion of wounds to the neck and abdomen than assault wounds. Injuries from assault wounds presented a higher Injury Severity Score, but more procedures were performed on self-inflicted stab wounds. Wound characteristics are not different between nonsuicidal self-injury and suicidal self-wrist cutting injuries. Consequently, trauma surgeons cannot determine a patient's suicidal intent based solely on the characteristics of the wound. In Korea, percent of usage of lethal weapon is increasing. In violence as well as murders, the most frequently used weapon is knife. In the crimes using knife, 4.8% of victims are killed. Therefore, the provision of prehospital care by an emergency medical technician is crucial.

RFID(Radio Frequency IDentification) is a wireless frequency of recognition technology that can be used to recognize, trace, and identify people, things, and animals using radio frequency(RF). RFID will bring about many changes in manufacturing and distributions, among other areas. In accordance with the increasing importance of RFID techniques, great advancement has been made in RFID studies. Initially, the RFID research started as a research literature or case study. Recently, empirical research has floated on the surface for announcement. But most of the existing researches on RFID adoption have been restricted to a dichotomous measure of 'adoption vs. non-adoption' or adoption intention. In short, RFID research is still at an initial stage, mainly focusing on the research of the RFID performance, integration, and its usage has been considered dismissive. The purpose of this study is to investigate which factors are important for the RFID adoption and implementation with organizational resources. In this study, the organizational resources are classified into either finance resources or IT knowledge resources. A research model and four hypotheses are set up to identify the relationships among these variables based on the investigations of such theories as technological innovations, adoption stage, and organizational resources. In order to conduct this study, a survey was carried out from September 27, 2008 until October 23, 2008. The questionnaire was completed by 143 managers and workers from physical distribution and manufacturing companies related to the RFID in South Korea. 37 out of 180 surveys, which turned out unfit for the study, were discarded and the remaining 143(adoption stage 89, implementation stage 54) were used for the empirical study. The statistics were analyzed using Excel 2003 and SPSS 12.0. The results of the analysis are as follows. First, the adoption stage shows that perceived benefits, standardization, perceived cost savings, environmental uncertainty, and pressures from rival firms have significant effects on the intent of the RFID adoption. Further, the implementation stage shows that perceived benefits, standardization, environmental uncertainty, pressures from rival firms, inter-organizational cooperation, and inter-organizational trust have significant effects on the extent of the RFID use. In contrast, inter-organizational cooperation and inter-organizational trust did not show much impact on the intent of RFID adoption while perceived cost savings did not significantly affect the extent of RFID use. Second, in the adoption stage, financial issues had adverse effect on both inter-organizational cooperation and the intent against the RFID adoption. IT knowledge resources also had a deterring effect on both perceived cost savings and the extent of the RFID adoption. Third, in the implementation stage, finance resources had a moderate effect on environmental uncertainty and extent of RFID use while IT knowledge resources had also a moderate effect on perceived cost savings and the extent of the RFID use. Limitations and future research issues can be summarized as follows. First, it is difficult to say that the sample is large enough to be representative of the population. Second, because the sample of this study was conducted among manufacturers only, it may be limited in analyzing fully the effect on the industry as a whole. Third, in consideration of the fact that the organizational resources in the RFID study require a great deal of researches, this research may deem insufficient to fulfill the purpose that it initially set out to achieve. Future studies using performance research are, therefore, needed to help better understand the organizational level of the RFID adoption and implementation.

건설산업 분야에서 빌딩정보모델링(BIM)은 단지 설계를 보다 쉽게 지원하고, 3차원 모델을 구현하기 위한 도구만은 아니다. 왜냐하면, 설계, 시공, 유지관리 및 철거에 이르는 건설 생애주기 동안의 다양한 데이터를 입력하고 관리가 가능하도록 구조화 되어 있기 때문이다. 이렇게 구조화된 모델을 가지고 다양한 분석 및 해석이 가능해지기 때문에 BIM의 역할은 점점 더 증대되어 가고 있다. 노르웨이 베스트바넨의 국립예술박물관 현상설계 경기를 시작으로 국내외적으로 BIM을 설계 경기 및 평가에 적용하려는 노력이 다각적으로 발생하고 있다. 이때, 기존 방식의 설계경기와는 다르게 BIM기반으로 전사적인 시뮬레이션을 통한 자동적이며, 신뢰성이 높고 효율적인 평가가 가능하게 된다. 이를 위하여 각 BIM 도구를 대상으로 하는 모델링 가이드가 필요하며 이를 검증할 수 있는 평가시스템의 요구가 생기게 되었다. 본 논문은 건설산업 분야에 새로운 패러다임을 이끌고 있는 BIM 기술을 이용한 새로운 방식의 설계평가 및 절차의 방향에 대해, 전력거래소 본사사옥 등의 이전 설계경기 사례를 비교분석하고 이에 대한 개선방안을 설명함으로써 향후 발주될 BIM기반 건축설계경기 평가의 방향을 제시하고자 한다.

본 연구는 의료 SCM 경쟁역량 강화를 위해 빅데이터 분석을 통한 물류공동화 시스템 도입의 필요성을 역설하면서 고객 니즈를 반영한 현 상황 시나리오 비즈니즈 모델을 개발하는 것이다. 물류공동화 사용의도에 필요한 의료 SCM 경쟁역량으로써는 협업시스템, 가격리더십, 인도속도, 프로세스유연성으로 구분하여 살펴보았다. 의료기관 간의 업무 효율화를 실현하기 위해 가장 중요한 고려 사항을 분석한 워드클라우드(wordcloud) 결과는 돌발상황, 정보공유, 배송, 실시간, 배송, 편리성 등의 단어가 많이 언급되었다. 주말에 긴급 돌발상황에 즉각적 대응을 할 수 있는 시스템 구축의 필요성을 피력한 것으로 해석할 수 있다. 또한 소통과 편리성의 추구와 더불어 재고관리의 효율성을 기할 수 있는 실시간 정보공유의 중요성을 엿볼 수 있다. 따라서 빅데이터 분석을 통한 실시간으로 물류파이프라인의 가시성을 높일 수 있는 비즈니스모델의 지향을 현장에서 필요로 한다는 판단이다. 의료 SCM 경쟁역량에 대한 공급사슬네트워크의 적응성의 효과를 분석함으로써 경쟁역량의 획득이 물류공동화 실행을 통해서 이루어질 수 있음을 밝히게 되었다. 물류공동화와 같은 파트너십이 강화될수록 결국 SCM 경쟁역량으로 이어지게 될 것이다. 의료기관의 공동물류화 시스템이 기업 상호간의 파트너십의 활성화를 유도할 수 있는 방향으로 기업 간 전략적인 접근을 모색하여 SCM 경쟁역량을 높일 수 있도록 하여야 할 것이다. 특히 물류공동화 시스템 구축에 따른 빅데이터 분석을 통하여 HSCM의 활용도 모색을 강구해 나가야 할 것이다.
