  • In the case of earthquake, it is necessary to install earthquake instruments and to measure the ground motions for stable gas supply and restoration in case of supply suspension. Because each point in the site of the gas facilities has different characteristics of ground motion, it is recommended to measure at the point where the ground motion is representative. In this paper, ground motion analysis and noise pattern analysis are carried out to select suitable point for the installation of earthquake instruments and to set of dynamic range of sensors.

  • Rectal stricture occurred in 2 finishing pigs submitted for necropsy from Moguchon, the meat processing plant, chonbuk. Grossly, the wall of the rectum was harden and thickened by fibrous tissue. Anteriro to the stricture, the descending colon was dilated up to 30cm in diameter, filled with gas and pasty green fluidal feces. Histologically, the epithelia of rectal mucosa were necrotized. The mucosa and submucosa of rectum were infiltrated by macrophages, eosinophils and lymphocytes. This infiltration was the most extensive in the deeper layer of submucosa and intensive fibrosis was observed in deeper submucosa layer. This case is report for rectal stricture of finishing pig.

  • Structural health monitoring is concerned with the safety and serviceability of the users of structures, especially for the case of building structures and infrastructures. When considering the safety of a structure, the maximum stress in a member due to live load, earthquake, wind, or other unexpected loadings must be checked not to exceed the stress specified in a code. It will not fail at yield, excessively large displacements will deteriorate the serviceability of a structure. To guarantee the safety and serviceability of structures, the maximum displacement in a structures must be monitored because actual displacement is a direct assessment index on its stiffness. However, no practical method has been reported to monitor the displacement, especially for the case of displacement of high-rise buildings because of not to easy accessive. In this paper, it is studied displacement measuring method of high-rise buildings using LiDAR The method is evaluated by analyzing accuracy of measured displacements for existing building.

  • Product Liability(P.L) is designed for system which charge with a compensation for demages that has nothing to do with whether manufacturer make a mistake or not in that case suffer heavy losses anyone of body or property by defect of product. Now and then, most people interest of safety of product and main countries already carry out Product Liability. This paper analyzes newly studied cases by defects, products, countries in Korea and some developed countries (USA and Japan mainly) in order to prepare for Product Liability, which will be enforced on July 1, 2002 in Korea. Before P.L. began to enforce, many cases have happened and resulted in sues. Therfore, each country have revised the current P.L. after many trials and errors. From this respect, the cases of other countries and Korea will be compared and analyzed.

  • Creep crack growth lift of high temperature pressure equipments was assessed for various crack locations and for various material properties. Surface cracks at the inner and outer surface of the vessel in the axial and circumferential directions were considered. The crack was located in the weld metal, in the parent metal or at the weld interface. Results shored that the crack at the weld interface was the most dangerous one. The crack located outside is weaker than that located inside. Safety factors of the case in which improper material properties were used the to unavailability of the correct material properties were discussed.

  • This paper was concerned about case study for preventing WMDSs(Work-related Musculoskeletal Disorders) by using Thinking Process of TOC(Theory Of Constraints), Unfortunately, the number of WMDSs are rising steadily in auto-part manufacturer. These WMDSs have on worse and worse influence not only on the competition of enterprise but on the life quality of a worker. The research results are helpful to establish the preventing WMDSs and improvement of workplace environments for small-medium sized auto-part company.

  • This study is to research on the condition of safe environment of kindergartens. This study is to supplement the preceding study which was based only on survey to show the result and analyze the condition and problems of the safety of kindergartens to suggest the basic database of indoor environment that cause accident. First as a theoretical study, we analyze the preceding studies according to the related regulations. And we made checklist based on this and visited and investigated two kindergartens where applied for the case study As the result, we could understand factors that can cause accidents from classroom, corridor, door, stairs, balustrade, toilet, kitchen, front door, and fire exit/shelter. Especially, in case of fire exit/shelter, the whole renewal of kindergarten was necessary which is difficult. But, though it can not be advanced right away, they should try to have facility expansion and repair works gradually. And for more study on this, active cooperation from kindergartens are in need.

  • In this paper, we studied on the growing characteristics of dendrite structure of melted wire deteriorated by over current. Electric wire was melted by Jolue's heat. By using HSIS(High Speed Imaging System), we found out a lot of melted parts of wire were dispersed and radiated. Electric wire had narrow melted areas in case of short fusing time. A lot of very small dots generated around the grain of copper cross-section and they were changed into dendrite structure. Dendrite structure appeared at the values lower than 2.5[A/sec]. In case of very short fusing time, fusing current was calculated by empirical formula. The Preece equation was not enough to analyze a variety of characteristics of melted wire because it did not consider melting time, atmosphere, etc.
