Moxa-combustion therapy makes use of heat stimulus and chemicals result form when cauterize the skin with moxa cones to medical cares. Despite an extensive evidence-base guiding the selection of stimulation parameters and attributes of subject, little methodologically research regarding the attributes of moxa cautery in need to provide effective stimulation. To determine moxibustion's effects of the three different moxa cautery made by three different company(as A, B, C), the small intestinal motility in rats were observed after moxibustion at ST36. Under anesthesia, each intensities(1, 5, 10 times), two regions(left and right at ST36) and a quantity(as number of 1, 5, 10 times at once) were applied to the groups divided with sex. In each intensities groups, the A product made increase with 5, 10 times in male and female group. The B and C product made increase with 10 times in male group and the B product made increase with 1, 5, 10 times and the C product made increase with 5 times in female group. In two regions(left and right at ST36) groups, the A and C product made increase with 1(right), 5(right) times and the B product made increase with 1(left), 10(left), 10(right) times in male group. In female group, the A product made increase with 5(left), 5(right), 10(right) times and the B product made increase with 1(left), 10(left), 10(right) times and the C product made increase with 5(left), 10(left) times. In a quantity(as number of 1, 5, 10 times at once) groups, the A and B product did not show any changes but the C product made increase with a quantity of 10 times in male group. In female group, The B product made increase with a quantity of 1 times and the C product made increase with a quantity of 5 times, but the A product did not show any changes. Three different moxa cautery made by three different company made differents result in each group divided with sex. With these results, it was suggested that we should consider the a process of manufacture and moxa cautery's quality for the adequate value of moxibustion.

In the previous study, several problems were observed in a NG conversion vehicle, which were fail of air-fuel ratio closed loop control, aggravated fuel economy, increased harmful emission and declined roadability. It was provisionally supposed that the mismatch of injection system with the engine caused these performance deterioration. In this context, the characteristics of fuel injection system of commercial conversion kit for NG were investigated experimentally varying the engine speed, fuel rail pressure and volume. The results are as follows; The injection quantity decreases as the engine speed increases due to the extremely small rail volume of the presenting system and flow rate of No. 2 injector are always lower than that of the other ones regardless of the speed under the dynamic operation condition. Furthermore the existing system does not meet the required fuel quantity for the normal engine operation over 3000 RPM. On the other hands, the large rail volume systems ease and/or eliminate the difference of injection quantity between the injectors according to the speed variation, however, these systems decrease injection flow rate and still cannot supply sufficient fuel. Finally, suitable combination of the higher rail pressure and the larger rail volume might be a solution about these problems.

This is an exploratory study to describe drinking patterns and alcohol-related problems (ARP) in women. A probability sample was drawn from Kyungnam Providence area 20 to 59 age by a multi- stage cluster sampling method and secondary data analysis was used. Drinking patterns in this study involve lifetime prevalence of alcohol use, year prevalence, month prevalence , frequency and usual quantity of drinking alcohol in a situation, ARPs were measured by employing a modified version of ARP developed by Alcohol Research Group in U.S.A. Three measurements were constructed to represent alcohol-related problems by summing up 41 alcoholic statements, which were consequence, social consequence and dependence. The results were as follows; 1) The lifetime prevalence of alcohol use in women was $80.3\%$ and year prevalence $78.3\%$. High prevalence rates of drinking were observed in the twenties who have at least community college diploma. and frequencies of alcohol use were increased as age increased. 2) More than $27.3\%$ of the respondents who were reported to experience at least a ARP in a year. 3) ARPs were associated with age, religion, frequency and usual quantity of drinking alcohol in situation. Issues were proposed with respect to research methodology and policy implications for public health.

Electron magnetohydrodynamic (EMHD) turbulence provides a fluid-like description of small-scale magnetized plasmas. Most EMHD turbulence studies consider "balanced" EMHD turbulence. However, imbalanced EMHD turbulence has never been studied. In this study, we numerically study "imbalanced" EMHD turbulence. Imbalanced turbulence means that wave packets moving in one direction have high amplitudes or strong perturbations than the others. In driven imbalanced EMHD turbulence, non-zero magnetic helicity is injected. When magnetic helicity is injected at a scale, we expect to have inverse cascade of magnetic helicity, as well as magnetic energy, in three-dimensional (3D) EMHD turbulence. For no helicity injection, we do not observe inverse energy cascade. However, when magnetic helicity is injected, inverse cascade of magnetic helicity is clearly observed. Magnetic energy also shows inverse cascade. In EMHD turbulence, it is well known that magnetic energy on scales smaller than the energy injection scale is forward-cascading quantity and the magnetic energy spectrum follows a k^{-7/3} one. On the other hand, the inverse-cascading entity on scales larger than the energy injection scale is uncertain. If the magnetic helicity is inverse-cascading quantity, we will obtain a k^{-5/3} magnetic energy spectrum. In our simulations, we do observe energy spectrum consistant with k^{-5/3} on large scales. Therefore, we confirm that magnetic helicity indeed is the inverse-cascading entity in 3D EMHD turbulence.

This study was conducted to develop a method to change the color of traditional Dongchimi using natural dyes to meet changing consumer demands. It was intended to improve the manufacturing process ability for color Dongchimi, and the best optimum extraction solvent and method from the natural dyes were proven to be confirmed and valid. The extraction process was evaluated using different solvents including distilled water, 20% ethyl alcohol, and 1% citric acid, and the quantity of the extracted anthocyanin was then measured based on the absorbance. The greatest absorbance was observed when 1% citric acid was used. Based on these findings, it would be most efficient to allow the traditional Dongchimi to produce citric acid naturally instead of using artificial additives during its production. Celosia cristata L. was extracted in its largest quantity when reacted with 20% ethyl alcohol. Therefore, instead of applying Celosia cristata L. to Dongchimi as the sub-ingredient during the preparatory stage, it will be more efficient to use Celosia cristata L. as the fractional ingredient in order to first extraction.
