Purpose: To compare and analyze current state of domestic and foreign educational program to develop a program and provide basic information for qualitative improvement of the program. Method: Referred to records and used various methods as searching on the Internet. Analyzing methods and standards are as follow : 1) As for the current status of domestic educational program, find out about organizations that conduct the program 2) As for the current status of foreign program, find out about United States, Canada and United Kingdom. 3) As for comparison and analysis, find out about curriculum, subject, the number of people, content, cost and time. Results: In comparison and analysis of subjects and program, United States, Canada and U. K. specified the subjects according to occupations to offer various programs appropriate for special occupational situations whereas domestic program only provide education of CPR and usage of AED. Foreign countries provide sufficient time from 5.5 to 40 hours according to occupations. In contrast, Korea only provide 2-4 hours of educations, which is insufficient to master techniques of first aid. In addition, foreign countries precisely regulate organizations that fulfill the qualification and specific guidelines for content of education. However, Korea doesn't have any standards of qualification or guidelines. Discussion: It is necessary to specify first aid education according to occupations to provide diverse programs. Furthermore, it is necessary to establish nationwide regulations for subjects and content of the programs of the first responder.

This paper presents the experimental results of relationship between the machinability and environmental consciousness due to cutting fluid atomization in machining process. Even though cutting fluid improves the machined part quality through the cooling and lubracating effects, its environmental impact is also increased according to the cutting fluid usage. Cutting tool wear is one of criterion for deciding the machinability. A few turning operations were performed to know the qualitative effectiveness of cutting fluid to tool wear improvement. This research can be used as a basis for environmental impact analysis on the shop floor. It can be also facilitate the optimization of cutting fluid usage in achieving a balanced consideration of productivity and environmental consciousness.

We developed and evaluated a method of short-term acute toxicity testing based on the feeding behavior of Ceriodaphnia dubia. In prior toxicity tests, neonates of C. dubia were hatched and cultivated with the addition of yeast only for the preparation of the transparent daphnid's gut. Scenedesmus subspicatus was supplied as food after 1 to 6 h of exposure to toxicants. The effects of 1-h and 6-h exposure time on test sensitivity did not significantly differ. A comparison of the short-term l-h acute toxicity test developed in this study to the standard 48-h acute toxicity test using heavy metals, cyanide, and pentachlorophenol indicated that the 1-h test provided an acceptable sensitivity level in toxicity testing of C. dubia..

Most of LV customer has been composed the 3-phase four wire system distribution system which is supplying simultaneously at the 1-phase & 3-phase load. In this system, the composition of the power apparatus system is simple rather than conventional separation mode of the 1-phase & 3-phase, But due to uneven load unbalance or unclean power quality, various kinds such as derating or power losses become an issue. In this paper, we measured and analyzed voltage and current waveform in the field, compared with internationally allowable voltage unbalance limits.
