  • Currently many geriatric hospitals have been built in Korea because increasing aging rapidly. However the increasing geriatric hospitals make the increasing safety accidents. Therefore this study is conducted by survey and face-to-face talk with the fire safety managers for analyzing safety problem of geriatric hospitals which number is twelve among 15 geriatric hospitals in the north of Chung-buk area. The result of this study is that geriatric hospitals are very old. Fire safety managers holding the fire safety license are a level 2 issued by the Korea Fire Safety Association(KFSA). And the fire safety inspection ability of them is normal (58%). Furthermore a fire safety budget ratio is 83% (A little) in the company yearly budget. And ratio having the fire inspection equipment in the building is 42% (A little) and 33% (Nothing). Satisfaction ratio of their duty is 66% and they also get stress from heavy duty and heavy responsibility. In conclusion, CEO needs to invest and interest the improvement of job performance, satisfaction ratio and fire safety facility. Also government needs the improvement of system to support and supervise the fire safety of geriatric hospitals consistently.

  • In Vehicle Safety Communication (VSC), noted as a representative application of VANET technologies, emergency warning messages (EWM) are broadcast over vehicles in response to an emergency situation. However, as the number of vehicles increases, the so-called Broadcast Storm Problem often occurs due to a huge number of redundant EWM transmitted. Though many approaches in the literature have been proposed to solve the problem, most of them require the preliminary phase for setting up or refreshing neighbor relationship through exchanging beacon messages with nearby vehicles, thereby further increasing the traffic load. In this paper, we propose Longest Leaping Relay (LLR) scheme which can efficiently solve the Broadcast Storm Problem without any preliminary phase for setting up neighbor relationship. Through computer simulations, we compared the performance of the proposed scheme with competitive schemes and verified the proposed scheme outperforms the existing schemes.

  • It has been recognized as an important issue to design optimally a firm's logistics network for minimizing logistics cost and maximizing customer service. It is, however, not easy to get an optimal solution by analyzing trade-off of cost factors, dynamic and interdependent characteristics in the logistics network decision making. Although there has been some developments in a system which helps decision making for logistics analysis, it is true that there is no system for enterprise-wise's on-site support and methodical logistics decision. Specially, E-biz process along with information technology has been made dramatic advance in a various industries, there has been much need for practical education closely resembles on-site work. The software developed by this study materializes efficient algorithm suggested by recent studies in key topics of logistics such as location and allocation problem, traveling salesman problem, and vehicle routing problem and transportation and distribution problem. It also supports executing a variety of experimental design and analysis in a way of the most user friendly based on Java. In the near future, we expect that it can be extended to integrated supply chain solution by adding decision making in production in addition to a decision in logistics.

  • This paper examines the effects on safety index analysis with Level II Second-Moment Method. The general two variable problem is examined by means of Cornell safety index ${\beta}c$ Rosenblueth-Esteva safety index ${\beta}_{RE}$ Rackwitz-Fiessler safety index by iterative method and Practical FOSM safety index ${\beta}_p$, which based partly on the concepts given by Paloheimo and Hannus, proposed the algorithm in this paper. The calculated examples have shown that safety index by Practical FOSM Method proposed in this paper would be similar to those in the method by Rosenblueth-Esteva or Rackwitz-Fissler and be simpler in calculation than the Rackwitz's Advanced FOSM Method, in which the iterative procedure has to be used.

  • Recently process industries from oil and gas procedures and mining companies to manufactures of chemicals, foods, and beverages has been exploring the USN (Ubiquitous Sensor Networks) technology to improve safety of production processes. However, to apply the USN technology in the large-scale plant industry, reliability and security issues are not fully addressed yet, and the absence of the industrial sensor networking standard causes a compatibility problem with legacy equipment and systems. Although this situation, process industry such as energy plants are looking for the secure wireless plant solution to provide detailed, accurate safety monitoring from previously hard-reach, unaccordable area. In this paper, SPSF (Smart Plant Safety Framework based on Reliable-Secure USN) is suggested to fulfill the requirements of high-risk industrial environments for highly secure, reliable data collection and plant monitoring that is resistant to interference. The SPSF consists of three main layers: 1) Smart Safety Sensing Layer, 2) Smart Safety Network Layers, 3) Plant Network System Layer.

  • The first tram in korea was commended the operation from 1899 to 1968 as a core role of public transportation. However, tram recently is being recognized as an alternative against a traffic congestion, a super-aged society and an environmental pollution problem. Because of these advantages, we are trying to introduce tram in korea. The efforts to introduce trams have focused on the economic analysis for tram construction. But we must be interested in tram operational safety. Early opening tram accidents could affect a negative impact on the additional tram introduction. We are trying to introduce trams in Daejeon, Wi-Rye and Su-won. In this paper, I want to check the safety issues in tram operation phase.

  • Standardization of disaster safety lexicon is important as the most basic process for successful accident prevention and response. A lack of understanding of disaster safety lexicon leads lack of communication and information sharing, which can be a problem in communicating with appropriate responses in case of a disaster. Currently disaster and safety control agencies produce and manage heterogeneous information and they also develop and use word dictionaries individually. To solve this problem, identifying differences of disaster safety lexicon patterns by the user are essential for standardization. In this paper, we conducted lexicon patterns analysis based on social media and revealed the characteristics according to pattern types. At the result, we proposed the standardization and construction methods of disaster safety word dictionary.

  • The availability of in-depth accident data is a prerequisite for each efficient traffic safety management system. Identification and definition of the relevant problem together with knowledge of the data and parameters describing this problem is essential for its successful solution. Comprehensive, up-to-date, accident data is needed for recognition of the scope of road safety problems and for raising public awareness. Reliable and relevant data enable the identification of the contributory factors of the individual accidents, and an unveiling of the background of the risk behaviour of the road users. It offers the best way to explore the prevention of accidents, and ways to implement measures to reduce accident severity. In this study, reviewing the existing iGlad and GIDAS system, KIDAS data format can be finalized through feasibility evaluation. The progressive approach is proposed to successful settlement of Korea in-depth accident study. As the initial stage of in-depth investigation DB construction, the KIDAS is not repetition of the current police based TAAS. It is essential part of improving vehicle safety and reduction of traffic fatality in Korea. 72 Contributing factors like road and traffic characteristics, vehicle parameters, and information about the people involved in the accident have to be investigated and registered as well in the KIDAS.
