  • The requirements of disaster prevention have been constantly increasing on highly disaster frequency by Global warming and environmental destruction. The damage occur more highly, especially when it's on the localized change of weather. It requires that we have methods of disaster prevention locally. In this paper, we design and implement a breakwater disaster prevention system integrated wireless sensor technique for the shore breakwater of East Sea that is raised anxiety about an accident occurrence due to stormy weather. The provided disaster prevention system perceive the seriousness of the situation that is chance of that happening by the information of realtime remote situation and a prediction system so that it could be of some help to reduce the damage of disaster and the cost of recovery.

  • The purpose of this study is to suggest school safety accidents prevention policy by applying delphi technique as a method to decrease school safety accidents which have been increasing consistently. As results of Delphi, the plans to improve school safety accidents prevention policy per area are as follows: First, it is required to establish systematic safety policy by dividing school facilities into four stages such as planning, designing and building, maintenance and evaluation etc. Second, it is required studies to overcome budget limitation and accountability of people in charge of safety of facilities to apply school safety policy as a useful measure. Third, it is required to make an effort to revise relevant legislations through examinations of relevant government ministries per each area to reflect prevention measures to safety policy consistently.

  • Since SMEs have recognized needs for industrial technique leakage prevention, they tend to construct information security system causing huge consumption of budget, yet they cannot organize information security team to operate integrated information security management system with consistency and it is fact that there only occur instant introductions of certain system. In this study, we designed information security management system for SMEs' industrial technique leakage prevention which is differentiated from those of large enterprises based on current status of SMEs' industrial technique leakage. Specifically we analyzed current status and vulnerability of SMEs' industrial technique leakage and we designed industrial technique leakage prevention management system for SMEs. Then we applied Delphi method to validate appropriateness of study result. We strongly believe that SMEs may estimate a appropriate level of investment on information security and develop countermeasures for control by utilizing this study result.

  • There are many and various problems due to a disease in the work. These problems result in serious social Problems such as individual and family Problem, economical loses of company. The objective of this study is to analyze the worker's consciousness and provide the precautionary measures far prevention of a disease in the work. Also, this paper presents quantitative value of priorities for prevention of a disease in the work using QFD technique. The samples for this study are chosen from the companies with less than 300 employees under charge of the Kangnung Ministry of Labor during three months (2002. 3. 2 - 2002. 5. 31).

  • In this study, experimental research was carried out to develop protective finishing, coating materials and new hybrid technique for deteriorating prevention and high durability in concrete structures. It had sufficiently recommended performance for the protective finishing method of concrete structures through testings. This is more progressive double membrane method than single membrane type designed by conventional method. It was found that this hybrid construction method had very excellent performance to improve the durability of existing concrete structures and attain the beauty of concrete structures.

  • The scanning laser source (SLS) technique has been proposed recently as an effective way to investigate small surface-breaking defects, By monitoring the amplitude and frequency changes of the ultrasound generated as the SLS scans over a defect, the SLS technique has provided enhanced signal-to-noise performance compared to the traditional pitch-catch or pulse-echo ultrasonic methods, An extension of the SLS approach to map defects in microdevices is proposed by bringing both the generator and the receiver to the near-field scattering region of the defects, To facilitate near-field ultrasound measurement, silicon microcantilever probes are fabricated using microfabrication technique and their acoustical characteristics are investigated, Then, both the laser-generated ultrasonic source and the microcantilever probe are used to monitor near-field scattering by a surface-breaking defect.
