The purpose of this study was to construct database for a drug safety information website to serve as an access point of up-to-date resources for a wide variety of drug-safety information helping patients and healthcare professionals make well-informed decisions about medication use. All the contents developed were confirmed by the council of advisors who were the experts in drug safety. The detailed contents of database on frequently prescribed drug including 9 NSAIDs, 19 antibiotics, 24 cardiovascular, 21 metabolic, 14 respiratory, 20 digestive, 22 hormonal, 10 genitourinary, 10 anti-allergic, 27 antifungal/antiviral, and 71 neuropsychiatric agents were developed based on the approved drug labeling of the Korean FDA. A separately searchable database of drug-specific safety information for patients and health professionals was constructed for users in need of different depth of knowledge on using medications safely. The safety information on highly prevalent chronic diseases and drug classes was also developed. Finally the most recent global drug safety news was provided. The consumer directed information was developed in layman's terms as means of proving user-friendly information. The creation of this type of website is part of the Korean FDA's ongoing initiative to address and promote the safe use of medications for the public.

현재 철도차량이 분기기 통과 시에 횡압의 변화가 최소화하는 설계가 요구되고 있다. 따라서 차량이 분기기를 통과하는 경우에 분기기에 작용하는 횡압 및 탈선계수를 예측하기 위하여 차량과 분기기간의 상호작용에 따른 동역학 해석을 수행하여야 한다. 본 연구에서는 분기기 단면 형상 변화가 차량의 주행안전성에 미치는 영향을 살펴보기 위해 포인트부, 크로싱부의 단면 형상 변화에 따른 주행안전성 해석을 수행하였다. F10/F12 분기기를 대상으로 포인트부 텅레일의 길이, 크로싱부 노즈레일의 높이를 변경시켜 주행안전성 해석을 수행하였다.

We could analyse the fire behavior using the developed software for fire safety assessment in a large space such as atrium. But Korean building law hasn't admitted the result of fire risk assessment in atrium. In the legislation fire resistant wall or shutter must be required between atrium and office rooms, That has obstructed development of building design and fire protection technique in Korea. From this point of view, we made scenarios of fire spread between atrium and office rooms, and then computed fire spread and fire phenomena using FASTLite and Breakl. In this study, we can decide that fire compartmentalization between atrium and office rooms doesn't require in Atrium building if the material and fire protection system were reliable. Consequently, Korean Fire Protection Regulations have to consider in direction of increasing freedom of building.

The main function of a reactor protection system is to maintain the reactor core integrity and the reactor coolant system pressure boundary. Generally, the reactor protection system adopts the 2-out-of-m redundant architecture to assure a reliable operation. This paper describes the safety assessment of a digital reactor protection system using the fault tree analysis technique. The fault tree technique can be expressed in terms of combinations of the basic event failures such as the random hardware failures, common cause failures, operator errors, and the fault tolerance mechanisms implemented in the reactor protection system. In this paper, a prediction method of the hardware failure rate is suggested for a digital reactor protection system, and applied to the reactor protection system being developed in Korea to identify design weak points from a safety point of view.

본 연구는 2-Propanol과 O-xylene의 혼합물의 인화점과 자연발화에 관한 연구이다. 인화점의 경우 2-Propanol과 O-xylene의 혼합비를 변화하여 측정하였으며, 2-Propanol은 $12^{\circ}C$를 구하였고, O-xylene는 $32^{\circ}C$를 구하였다. 자연발화의 경우 2-Propanol과 O-xylene의 농도를 변화시켜 혼합한 시료를 만들어 최저발화온도와 순간발화온도를 측정하였다.

본 연구는 4차 산업혁명과 관련하여 각광을 받고 있는 가상현실 기술을 화재재난 대비를 위한 훈련과정에 도입하기 위한 연구이다. 최근에 발생한 제천화재와 밀양화재 사례가 보여주는 것처럼 화재재난을 대비하기 위한 화재재난훈련의 필요성은 계속적으로 커지고 있다. 재난발생시 사람들은 정신적 혼란 상태에 빠지게 되며 이를 재난인격이라 한다. 재난에서 생존하기 위해서는 재난상황을 미리 경험하여 자신의 재난인격을 극복할 수 있는 힘을 길러야 한다. 따라서 재난인격을 극복하기 위한 훈련이 필요하며 가상현실은 물리적 공간이 없이도 체험이 가능하다는 점에서 훌륭한 훈련수단이 될 수 있다. 또한 가상현실의 단점을 보완하기 위해 주기적인 실제 재난대피훈련을 병행해야 한다. 가상현실을 이용한 화재재난훈련을 도입하여 국민에게 보급하기 위해서 과거 정보화사업 중에 성공한 국민 PC 사업을 벤치마킹한 국민 VR 사업을 도입해야 한다. 또한 안전대비 훈련 전체를 포괄할 수 있는 국민안전포인트 제도를 도입하여 재난대비훈련과 건축물 보강 등을 통합적으로 관리해야 한다. 국민 VR 사업과 국민안전포인트제도가 성공적으로 도입된다면 한국이 '재난공화국'이라는 치욕적인 별명을 벗어날 수 있는 기반이 될 것이다.

지난 10년간 모든 산업의 재해율이 꾸준히 감소하고 있는 반면 건설업의 재해율은 증가 추세에 있어 개선이 시급한 실정이다. 본 연구의 목적은 국내 디자인 안전성 검토 시스템을 해외 사례와 비교 분석하여 국내 디자인 안전성 검토 시스템의 문제점을 도출하고 개선 방안을 모색하는 데 있다. 영국이나 싱가포르처럼 작업설계 초기부터 재검토해야 하고, 건설업 재해 경감을 위한 대규모 건설뿐 아니라 소규모 건설에서도 안전성 검토가 이뤄져야 한다. 특히 관련 제도 미비 등에 대한 제도 마련이 필요한데, 안전시스템 설계는 사업자 중심의 안전관리 체계에서 스펙트럼을 확대하는 것으로 향후 충분한 개선과 연구가 필요하다는 점에서 의미가 있다.

A Large Eddy Simulation(LES) was performed for the prediction of unsteady dispersion behavior of hydrogen fluoride (HF). The HF leakage accident occurred at the Gumi fourth industrial complex was numerically investigated using the Fire Dynamics Simulator (FDS) based on the LES. The accident area was modeled three-dimensionally and time-varying boundary conditions for wind were adopted in the simulation for considering the realistic accident conditions. The Message Passing Interface (MPI) parallel computation technique was used to reduce the computational time. As a result, it was found that the present LES simulation could predict the unsteady dispersion features of HF near the accident area effectively. The dispersion behaviors of the leaked HF was much affected by the unsteady wind direction. The LES could predict the time variation of the HF concentration reasonably and give an useful information for the risk analysis while the prediction with the time-averaging concept of HF concentration had a limitation for the amount of HF concentration at specific location point. It was identified that the LES is very useful to predict the dispersion characteristics of hazardous chemicals.

An error analysis of PPP (Precise Point Positioning) using IF (Ionosphere Free) combination is given in this paper. It is shown that the performance of the ordinary model with positions, clock bias, integer ambiguities and ionosphere delay as unknowns is equivalent to that of an ionosphere difference combination where ionosphere delay is cancelled out. Furthermore, it is shown that IF combination is an ionosphere difference combination but not unique. It is also proved that all difference models show same performances. The error analysis evaluated with a hardware simulator and real measurements show that the ionosphere delay is effectively eliminated by IF combination or equivalently by the ionosphere difference combination. However, if bias errors such as troposphere, clock bias or multipath are included in the measurements, the performance of the IF combination is degraded because the bias errors are amplified by the ionosphere difference operation.
