The crude methanolic extract of the bark of Cerbera odollam Gaertn. was evaluated for its possible antinociceptive and neuropharmacological activities in animal models. At the dose of 250 and 500 mg/kg body weight, the extract showed a significant antinociceptive effect in acetic acid induced writhing in mice comparable to that produced by aspirin, used as standard drug (P<0.001). The extract significantly reduced the time of onset of sleep (P<0.01) and potentiated the pentobarbital induced sleeping time in mice at the dose of 400 mg/kg of body weight significantly (P<0.001). It also decreased the open field score in open field test significantly at the dose of 400 mg/kg of body weight (P < 0.05). The obtained results tend to suggest the probable antinociceptive and neuropharmacological activities of the crude extract.

The purpose of this study was to identify kitchen and non-kitchen use of space for cooking and dining. Three rural villages, Kum-sung Ri, Young-san 1 Ri, and Yu-bang 2 and 5 Ri were selected for this study. Present and past use of space for cooking and dining was investigated by the field survey method. The major findings were that : 1) Both the kitchen and other space such as the outdoor courtyard(madang) were the space for cooking. 2) Dining activities took place in ondol rooms, the wooden floor room(maru), outdoor court yard(madang) and kitchen. In the winter eating activities took place in the kitchen where heating is provided. Many village people ate at a Western style or at a Korean style dining table(papsnag) in the kitchen. 3) Compared with study I, the present research found similar use of space for cooking and eating, with slight differences in space for eating.

I summarize highlights from extragalactic research activities performed with AKARI infrared space telescope. The main emphasis will be given to the works carried out by Korean astronomers. The activities span a wide range of topics, such as MIR properties of nearby galaxies in cluster environment, MIR diagnosis of star-forming galaxies at z=0 through z=2 in the North Ecliptic Pole (NEP) survey field, the Extended Groth Strip (EGS), and the First Look Survey (FLS) field, and the NIR spectroscopy of Luminous Infrared Galaxies (LIRGs) and Active Galactic Nuclei/Super-massive Black Holes at low redshift as well as near the re-ionization epoch of z~6. I describe FIR and MIR all sky data which can be used as a precious resource for extragalactic research, and other future and ongoing works with AKARI. These AKARI results will form a strong basis for future studies using other facilities, such as infrared surveys with UKIRT, FIR study of dusty universe with Herschel, and the SPICA mission.

Recently, there has been constituted the government regulations and the normative methods to control the safety management activities in construction fields, but almost of these regulations are ineffective, because of some characteristics safety management have. The needs of the times make government regulations and the normative methods change to autonomic management methods. In this context, it is significant certainly to improve the standard of safety management that is used as a tool to protect the workers from the accidents or industrial disasters in the construction field. In this research, it will be showed that the outside regulations and safety management systems of the head office have their limits to reflect the safety managements of field participants. Then, it will be presented the improved model of self-control safety management activities which is essential for success safety management.
