To investigate the actual conditions on the living environment of group-homes for the elderly and their living environment, 4 group-homes were surveyed. As the results, conditions of location for the group-home of the elderly looked positive, on the other hand, safety for criminal prevention, accessability and convenient facilities were not on level satisfied. The average area of each space in the group-home indicated that the bed room was $11.21\;m^2$, the living room $28.13\;m^2$, the kitchen $23.59\;m^2$, and the bath room had an integrated type of bath room and toilet $7.63\;m^2$. The physical environments of each space in the group-home were investigated, In bed room, door, windows and illumination were relatively good but safety was extremely inferior. Living room mostly looked good except the doorsill which needs refurbishment. In kitchen, cooking table, windows, illumination, ventilator were somewhat satisfactory but gas-warning device should have been installed. In addition, in bath room and toilet, location, door, window, illumination and finished material were satisfactory. But the stepped difference between the bath room and other space, safety-bar, emergency bell and floor heating system were seriously deteriorated and must be improved for the safety of the elderly. Conclusively, living environment of group-home for the elderly is mainly satisfactory but it was necessary to take a consideration for their safety.

Ni coating was carried out by pulse plating at room temperature. So, experimental conditions for Ni-coating were based on Watt's bath, and new additives(propionic acid) were introduced in the Watt's bath electrolyte as $H_3$$BO_3$ alternatives. By adding propionic acid, coating layer demonstrated a good adhesion and uniformity without special pre-treatment of the 316L stainless steel at room temperature. With a decrease of amount of propionic acid and applied average current density, cathode current efficiency increased. Also, edge effect was decreased with decreasing a peak current and increasing a pulse frequency in the same bath condition. It was found that the optimum condition for Ni coating was a current density of 10~20mA/$\textrm{cm}^2$ at below 500 mA peak current in the $5m\ell/\ell$ propionic acid solution.

Tc-99m labeled sestamibi ($^{99m}Tc$-MIBI) is one of most widely used radiopharmaceuticals for myocardial SPECT imaging. Radiolabeling of $^{99m}Tc$-MIBI is recommended by heating in $100^{\circ}C$ water bath for 15 min. However, the water bath might be a source of contamination. Thus, if radiolabeling of $^{99m}Tc$-sestamibi can be performed at room temperature, then it would be more convenient to use in clinical application. In this study, we performed the radiolabeling of $^{99m}Tc$-MIBI in different temperature conditions or using different instruments to find out the efficient labeling condition. We studied the $^{99m}Tc$-MIBI labeling at room temperature or $100^{\circ}C$ heating block, and checked the labelling yields every 1 min for 10 min using radio-TLC with 2 different eluents-saline and acetone. From the experiment, we confirmed that the $^{99m}Tc$-MIBI can be labeled over 90% yield but not completed at room temperature. However, the $^{99m}Tc$-MIBI labeling was completed when it was performed in the $100^{\circ}C$ heating block. Finally, we proved that heating is essential for complete $^{99m}Tc$-MIBI labelling, furthermore using heating block is also possible instead of water bath.

In order to dye polyester/cotton blend fabric by one-bath dyeing process with single disperse dye, a novel hetero-bifunctional bridge compound(DBDCBS) was synthesized and utilized. The DBDCBS was designed to contain two different reactive groups such as ${\alpha},{\beta}$-dibromopropionylamido and dichloro-s-triazinyl groups. The ${\alpha},{\beta}$-dibromopropionylamido group shows considerable reactivity towards amines or amino groups at acidic condition and high temperature. In contrast, the dichloro-s-triazinyl group has reactivity towards hydroxyl groups at alkaline condition and room temperature. In order to examine whether as a bridge the compound could combine dyes containing amino groups with cellulosic substrates, disperse dyes containing amino group were tried to dye the cotton fibers pretreated with the DBDCBS compound. By the results, polyester/cotton blends were dyed by one-bath dyeing process with single disperse dye,1,4-diaminoanthraquinone.
