Post-traumatic stress disorder (PTSD) is a serious problem not only among workers who experience industrial accidents but also among workers who witness such accidents. Early intervention is needed to prevent prolonged psychological problems. There has been no study conducted regarding the psychological problems of and interventions for bystander workers in Korea. This study introduces the experience of intervention on psychological problems at the Busan Workers' Health Center workers who witnessed their colleagues' death. An investigation and an intervention were conducted according to the Korean Occupational Safety and Health Agency (KOSHA) Guide. In total, 21 individuals including indirect observers showed statistical differences on scores of the Impact Event Scale Revised and the Patient Health Questionnaire 9 after the intervention. Future interventions and research involving a larger sample size over a longer period are needed. The KOSHA Guide could be a useful tool for urgent psychological intervention in the event of major workplace disasters.

59세의 기왕력 및 가족력에 특이사항이 없는 남자가 가슴통증을 호소하다 의식을 잃고 쓰러지자 이를 목격한 가족이 119에 신고하였다. 응급의료상담원의 도움에 의해 목격자가 심폐소생술을 시행하였고 거주 중인 아파트에 설치된 자동심장충격기를 이용하여 제세동 1회를 시행하였다. 이후 도착한 119구급대에 의해 제세동 2회 실시 후 자발순환회복되어 인근 응급의료센터로 이송되었으며, 저체온 치료 15일 후 대퇴수행분류 1점으로 퇴원하였다. 현재 우리나라의 응급의료전환상담원 도움에 의한 목격자 심폐소생술 및 제세동의 시행은 시작 단계이지만 본 증례를 통해 충분한 효과를 볼 수 있다고 판단되며, 이에 따라 응급의료전화상담원의 적극적인 자동심장충격기 사용 안내와 그에 맞는 체계적인 교육이 필요하다. 특히 훈련받지 않는 목격자의 자동심장충격기의 사용을 도울 수 있고, 119구급대가 현장까지의 반응시간이 지연되는 원거리 지역에서 중요한 의미를 가질 것으로 사료된다. 또한 우리나라 PAD 프로그램의 양적인 보급뿐만 아니라 목격자의 접근성을 높일 수 있는 방안이 될 것이다.

본 연구는 고속충돌에 따른 파괴로 인하여 발생한 파편들의 분산거동을 예측하기 위해 고속충돌 실험과 함께 재료거동 모델링 및 수치해석을 수행하였다. 알루미늄 합금과 강철로 각각 구성된 2종류의 위협체 및 표적판에 대해 충돌실험을 수행하였으며 위협체는 약 1 km/s의 속력으로 표적판과 충돌하고, 이 충돌로 인하여 발생한 파편은 알루미늄 합금 관측판에 손상을 유발시키게 하였다. 사용된 소재의 차이에 의해 파편의 분산거동이 상이하였으며 이에 따라 관측판에 형성된 파편의 분산 반경 또한 다름을 확인하였다. 수치해석은 실험과 동일한 조건하에서 수행되었으며 파편으로 인한 파괴 및 손상을 모사하기 위하여 입자완화 유체동역학(smoothed particle hydrodynamics, SPH)기법과 유한요소(finite element, FE) 연계 기법을 적용하였다. 실험 측정된 결과와 해석값을 비교분석한 바, 표적판의 관통부 지름과 관측판상의 파편 분산반경은 5 % 이내의 오차로 잘 일치하였다. 아울러 강철 위협체와 강철 표적판이 충돌한 경우 가장 큰 분산반경을 보임에 따라 타 경우에 비해 가장 위협적임을 알 수 있었다.

We witness now the changing techno-economic paradigm and the emerging learning economy. Reflecting on these changes, the group of Evolutionary Economists study recently the theory on regional innovation system, but their research results are still now not theoretically ‘systemized’. Moreover, they often indeed speak of the ‘social capital’, but do not investigate that. This paper tries to systemize their empirical findings and theoretical results and integrate the discussions on social capital in fields of sociology into a mathematical model. This study emphasizes the role of social capital in the innovating process.

The author presents the history of introduction of biofeedback system into Korea, depending on his personal experience at the Seoul National University Hospital. He, as the witness of biofeedback applied to clinical psychiatry and research in Korea, maintains that biofeedback should receive much more attention filled with enthusiasm, particularly because of the rapid development of medical engineering backed up by the unimaginable progress of computer- and neuro-science.

It is not uncommon to witness brand image transference which is a development of corporate image from a collection of individual brand images. The brand image transfer process is the influence of consumer attitudes toward certain brands on overall evaluation of the company. To understand the image transfer process, we examine the influence of brand level evaluation on overall company evaluation through food and beverage consumer products in China, where active competitions among global brands exist.

Jehovah`s Witnesses who require cardiac operations represent a challenge to surgeon because of the patients` refusal to accept blood transfusion, We report a 6 year period, ending May, 1991 with a consecutive series of 25 Jehovah`s witnesses. Patients ranged in age from 11 months to 61 years. All operations were performed during cardiopulmonary bypass with bloodless priming, No patient received any blood or blood products during hospitalization. Perioperative mortality was 2 paients[8%]. We conclude that if we performed the cardiac surgery with careful operative technique and various blood conserving procedures, we can do the bloodless open heart surgery with relatively safety.

In a car accident in Kyongju, each of the two occupants insisted that he was not driving the car. The accident was investigated to determine who the driver is through careful review of the collision report, the statements of accident and witness, photographs taken at the scene, and the expert report of the National Institute of Scientific Investigation. The accident was reconstructed based on the physical principles, injuries of occupants, damages of the involved vehicles and their final stops. A mistake was found in the expert report.

The Japanese Aviation Accident Investigation Board has two faces. While the surface of the Board is a one of the very accident investigation organ, its shadow face is a one of the very expert witness drawing up a requested written opinion for the sake of the criminal investigation of the Police under the two secret inter-ministerial accords. This Paper proposes that some evidence obtained by investigation ought to be protected for disclosure and use by privilege derived from on of our most basic legal principles: "Nemo debet se-ipsem accusare-no one is required to incriminate oneself-".
