This study has been conducted to present reform recommendations for Standardization of Construction Materials, based on a study on the Investigation of Demander's Consciousness for Construction Materials Quality and Information Standardization in Korea. Upon investigation, it was found that the quality of Korea Industrial Standards (KS) was given 67 points (out of 100) by respondents. In addition, 38% of the respondents showed that they had problems with a lack of Standardized Information. Good examples were found to be non-standardized materials, e.g. admixtures, waterproof agents, reinforcing fibers, concrete, aggregates, adhesives, wood, temporary materials, thermal-insulating materials, etc. Upon results from the investigation of demander's consciousness for infrastructure of standardization of information, 71.2% of respondents thought that it is necessary to informatize construction materials. They made following demands on the informatization to be, in order: Quality, Standard, Price (Cost), Operation, Drawing, Law, and Information.

In this paper, we discussed the hazard of ignition on the bimetal type thermostat molded by phenol resin with case study and accelerated aging test. We experimented three type thermostats molded by phenol resin which are used on hot/cold water dispenser. On the case study, the thermostat was origin of 6re and dry tracking occurred around it's moveable contactor. On the accelerated aging test, the more thermostat was switched, the more damaged it become. One of the A-type thermostats that is similar type on the case study fired around moveable contactor. We therefore confirmed that the tracking around the moveable contactor of bimetal type thermostat molded by phenol resin could be origin of fire and it is available to reduce of fire that using noncombustible material for molding of bimetal type thermostat.

Satellite imagery is generally used for investigating the damage from natural disaster for wide area and remotely piloted vehicle or aerial photos are used for the local damage. But for more detailed information such as damages of public facilities, these methods are inadequate and so in this case field surveying has been carried out. We tried to estimate the damage of public facilities faster and more accurately using photogrammetric method. We developed a digital stereo camera system by fixing two digital cameras on a frame, and with this system the photos of actually damaged areas were collected. The damages were estimated from these stereo photos. Then the estimated data was compared with field surveying data in order to verify our system.

This paper analyzes the hazard related to train control, the functional requirements for atrain control system(TCS) and the automatic train protection(ATP) functional allocation that ensures the interoperability of a radio communications-based TCS. In addition, the interoperability can be obtained using wireless communications technology standards and standardized functional allocations of TCS performed on the wayside and onboard. Using this information, an integrated operating system for a rail network can be constructed. The functional allocations of TCS that support interoperability, require hazard analysis of TCS and definition of the system requirements. The hazard factors for a TCS are confirmed through setting the train safety space control and train speed limit excess. Furthermore, this paper determines the impact of the hazard factors on the TCS and, defines the functional requirements for the TCS subsystems and the ATP wayside and onboard functional allocations.

On behalf of hazard mitigation, cases of investigation methods on levee are described. In general, failures of levee are caused by piping, water leakage through ground under the levee in Kimpo, Ilsan etc. Several phenomena against levees should be protected through consideration of analysis and quality control stage during construction. In this paper, protection methods against failures should be investigated by case studies.

This study assessed the biological and physicochemical hazards involved in establishing a hazard analysis critical control point (HACCP) for canned seasoned Broughton's ribbed ark Scapharca broughtonii and examined the critical control points (CCPs) in the field. Following the basic principles of the HACCP system, the hazard-evaluation procedures were enacted during the production of canned seasoned Broughton's ribbed ark after field investigation of a seafood product company in Korea. CCPs were determined using canned seasoned Broughton's ribbed ark with the corresponding control measures. The HACCP system was applied to each step in processing the product. The results indicated that inspection of raw materials, filling, sterilization, and alien substance detection were the most important CCPs. These results can be used to prevent and control food safety problems in the production of canned seasoned Broughton's ribbed ark.

Great concerns on geotechnical risk & hazard assessment have been increased due to human and economic damage by natural disasters with recent global climate changes. In this paper, geotechnical problems in particular, landslides which is interested in European countries and North America, were mainly discussed. For these, 18 key topics on geotechnical risk and hazards which had been discussed at the LARAM 2008 workshop in Italy were analyzed after grouping by subjects. Main topic contents consisted of applications such as field measurement, early warning systems, uncertainty analysis of parameters using radar, optical data and statistical theory and so on. And the problems related to analysis of vulnerability and deformation due to earthquakes, investigation of gas zone using seismic reflection data in a landslide area, risk quantification and hazard assessment of landslide movements and multi-dimensional analysis for stability of complex slopes were attracted. Also, there were studies on risk matters of cultural heritage, the blockglide of clayey ground, simulations of debris flows based on GIS, quantification of the failure processes of rock slopes, a meshless method for 3D crack modelling, and finally risk assessment for cryological processes due to global warming.
