The purpose of this study was to investigate the effect of moxibustion heat therapy(Koryo hand acupuncture) on menstrual cramps. dysmenorrhea and ADL. The experiment was carried out during the period from March 24 to April 30, 2003. The subjects in the study were drawn from female students attending two colleges in Chungcheongbuk-do and Kyunggi-do. Of all those subjects. 19 and 14 subjects were assigned to the experimental and the control groups respectively. The moxibustion heat therapy were performed three times a week, subjects were treated twice a time. Data was analyzed using SPSS/WIN10.0 by $x^2$test. Wilcoxon sign rank. and Wilcoxon rank sum test. The result of this study were as follows : 1) After moxibustion heat therapy. the graphic rating score of menstrual cramps was decreased significantly from 7.79(SD=1.22) to 4.47(SD=2.25) in experimental group(z=-3.731. p=.000). And there was significant difference in the change of graphic rating score of menstrual cramps between both groups(z=-3.637. p=.000). 2) After moxibustion heat therapy. the score of face rating scale of menstrual cramps was decreased significantly from 3.95(SD=0.71) to 2.32(SD=1.00) in experimental group(z=-3.457. p=.000). And there was significant difference in the change of face rating score between both groups(z=-2.713. p=.007). 3) After moxibustion heat therapy. the score of adjective labor pain rating scale rank (ALPRS) of menstrual cramps was decreased significantly from 23.63(SD=4.19) to 17.27(SD=6.34) in experimental group(z=-2.941. p=.001). But there was no significant difference in the change of adjective labor pain rating score(ALPRS) of menstrual cramps between both groups(z=-1.918. p=.059). 4) After moxibustion heat therapy. the score of dysmenorrhea was decreased significantly from 7.0(SD=2.89) to 5.26(SD=3.54) in experimental group(z=-2.183. p=.029). But there was no significant difference in the change of the score of dysmenorrhea between both groups(z =-1.555. p=.125). 5) After moxibustion heat therapy, the score of ADL difficulty was decreased significantly from 33.26(SD=4.58) to 28.83(SD=9.44) in experimental group(z=-3.552. p=.000). And there was significant difference in the change of score of difficulty of ADL between both groups(z=-4.110. p=.000). The above finding indicated that the moxibustion heat therapy showed a practical effect on reducing menstrual cramps, dysmenorrhea and ADL difficulty in female. Accordingly. we can adopt the moxibustion heat therapy as a useful intervention in the community nursing.

The roughness of rock joint surfaces is considered a critical factor in determining the stability of underground spaces and tunnels, leading to attempts to measure it using various devices. This study explored the applicability of portable 3D scanner for measuring rock joint roughness in comparison to laser scanner. By constructing various one-dimensional roughness profiles using laser scanner and portable 3D scanner, and calculating the Z₂(statistical roughness parameter) for comparison, it was found that the portable 3D scanner tends to underestimate roughness compared to the laser scanner. The variations in roughness and Z₂ showed very similar patterns between the two devices. Through Direct shear tests that induced wear on the specimens, differences in roughness and Z₂ due to wear were compared using the portable 3D scanner, confirming variations in roughness height and Z₂ related to wear.

The neutral complexes $MCl_3(phda)(MeCN)]$ and $[MCl_3(PPh_3)_2(MeCN)]$ (M=Mo, V) were prepared by the reaction of $MCl_z$, (M=Mo; z=5, M=V; z=3) with N, P-donating ligands in acetonitrile solution. Addition of AgClO_4$ to these neutral monomeric complexes in acetone solution afforded $MCl_{3-n}L_2(MeCN)(S)_n](ClO_4)_n$ (n=1, 2 : s=solvent). Two types of asymmetrical homo- and hetero-dinuclear complexes have been synthesized. The type of chloride bridged dinuclear complex is $[(MeCN)(phda)ClM({\mu}-Cl)_2M'Cl(PPh_3)_2(MeCN)](ClO_4)_2.$ And the type of pyrazine bridged complex is $[(MeCN)(phda)Cl_2M({\mu}-pyz)M'Cl_2(PPh_3)_2(MeCN)](ClO_4)_2.$ These complexes were characterized by elemental analysis, $^1H,\;^13C$ NMR, IR, Far-IR and UV-Vis spectroscopy.

As important intermediates for blue emitting materials of organic light-emitting diodes, bromotriphenylethylene derivatives for distrylarylenes are prepared by reactions of bromobenzophenone with benzylphosphonates. The reaction produces a 60 : 40 mixture of (Z)- and (E)-geometric isomers that are difficult to be resolved. The (Z)-isomer is successfully isolated by a selective recrystallization process using 2-propanol as a solvent. The X-ray structure analysis of (Z)-isomer shows that dihedral angles between tert-butylphenyl ring and bromophenyl ring and between bromophenyl ring and phenyl ring are $56.5(4)^{\circ}$ and $74.1(4)^{\circ}$, respectively.

The objectives of this study were to investigate the psychoacoustic properties of PTFE(Poly tetra Fluoroethylene) laminated vapor permeable water repellent fabrics which are frequently used for sportswear, to examine the relationship among fabrics' basic characteristics, mechanical properties and the psychoacoustic properties, and finally to propose the predicting model to minimize the psychoacoustic fabric sound. A total of 8 specimens' frictional sound were recorded and Zwicker's psychoacoustic parameters such as loudness(Z), sharpness(Z), roughness(Z), and fluctuation strength(Z) were calculated using the Sound Quality Program. Mechanical properties of specimens were measured by KES-FB system. Loudness(Z) of specimen D-1 was the highest, which means the rustling sound of the specimen D-1 was the most noisy. Statistically significant difference among film type was observed only in loudness(Z) for fabric sound. Based on ANOVA and post-hoc test, specimens were classified into less loud PTFE film group (groupI) and loud PTFE film group (groupII). Loudness(Z) was higher when staple yarn was used compared when filament yarn was used. According to the correlation between the mechanical properties of fabrics and loudness(Z) in groupI, the shear properties, compression properties and weight showed positive correlation with loudness(Z). According to the regression equation predicting loudness(Z) of groupI, the layer variable was chosen. In groupII, variables explaining the loudness(Z) were yarn types and shear hysteresis(2HG5).

Synthesis and biological activity test are described for the (Z)-9-tetradecen-1-yl acetate(1) and (Z)-11-tetradecen-1-yl acetate(1) and (Z)-11-tetradecen-1-yl acetate(2), the sex pheromone of the summer fruit tortrix moth, Adoxophyes orana. 8-Bromoctan-l-ol THP ether was prepared from 8-bromoctan-l-ol. The lithium anion of 1-hexyne was alkylated with 8-bromoctan-l-ol THP ether gave 9-tetradecyn-l-ol THP ether. Catalytic hydrogenation over Pd/BaSO4 followed by deprotection afforded (Z)-9-tetradecen-l-ol. Acetylation gave (Z)-9-tetradecen-1-yl acetate(1). l0-Bromodecan-l-ol THP ether was obtained from l0-bromodecan-l-ol. In liquid ammonia with THF and HMPA as cosolvents, sodium acetylide could be alkylated with 10-bromodecan-l-ol THP ether to give 11-dodecyn-l-ol THP ether. 11-Dodecyn-l-ol THP ether was then treated with n-BuLi in THF to give the lithium acetylide, which was alkylated with bromoethane to afford 11-tetradecyn-l-ol THP ether. Catalytic hydrogenation, deprotection, and acetylative gave (Z)-11-tetradecen-1-yl acetate(2). The synthetic pheromone thus obtained was attractive to the males of the summer fruit tortrix in the field.
