The aim of the study is to provide fundamental information for the development of magneticfluid actuator. To achieve the aim, the force and dynamic characteristics of magenticfluid are investigated by experiment for the various of tube diameter, height and position of magneticfluid column in magneticfield according to supplied voltage of solenoid coil, wave form and frquency. From this study, actuating force of magneticfluid is generated by magneticfield. The magnitude of force increases as the intensity of magneticfield becomes strong and the center of magneticfield becomes lower than the center of magneticfluid column. And the force of magneticfluid relates to the volume of magneticfluid more than the height and diameter. The response delay time decreases as the height of magmeticfluid more than the height and diameter. The response delay time decrease as the height of magneticfluid column becomes longer and the center of magneticfield becomes lower than the center of magniticfluid column. But, the approaching time increases as supplied voltage becomes higher and the center of magneticfiled becomes higher than the center of magniticfluid column. The frequency generating maximum force is 1Hz and the critical frequency is about 4Hz.

Objectives : The aim of this study is to examine the effect of external application containing herbal extracts (Betula platyphyllae Cortex, Viticis Fructus, Agrimoniae herba) to patients with atopic dermatitis. Methods : Twenty patients (experiment group) were treated with the external application containing herbal extracts (Betula platyphyllae Cortex, Viticis Fructus, Agrimoniae herba) and other twenty patients (control group) were treated with normal external application that doesn't contain herbal extracts for 2weeks. We observed comparisons between experiment and control group after 1week, 2weeks. Degrees of severity of atopic dermatitis were measured by SCORAD index (Scoring of Atopic Dermatitis Index). Statistical significance was achieved if the probability was less than 5% (p<0.05). Results : 1. After 1week of external application treatment, SCORAD Index in experiment group was significantly decreased comparing with control group, which is a marginally significant result between two groups. But after 2weeks the experiment group showed no statistically significant result. 2. After 1week of external application treatment, Intensity Criteria (Erythema, Edema/papulation, Total) in experiment group was significantly decreased comparing with control group, which is a statistically significant result between two groups. But after 2weeks the experiment group showed no statistically significant result. 3. After 1week and 2weeks of external application treatment, comparison of changes in Subjective Symptoms (Pruritus, Insomnia) indicated that the experiment group showed no statistically significant result. 4. After 1week of external application treatment, Total Quality of life through Skindex-29 in experiment group was significantly decreased comparing with control group, which is a marginally significant result between two groups. But after 2weeks the experiment group showed no statistically significant result. Conclusions : As a result of applying the external application containing herbal extracts to patients with atopic dermatitis and watching the progress, we can speculate that the external application containing herbal extracts has especially short-term therapeutical effects in mitigating the symptoms of Atopic Dermatitis. Thus, it is concluded and considered that the external application containing herbal extracts can be used by atopic patients effectively with almost no side-effect.

The aim of these experiments was to investigate the effects of bovine oviduct epithelial cells (OEC) derived from different segments to bind sperm binding and maintain their motility in vitro. In experiment 1, the number of sperm attached to OEC derived from isthmus or ampulla, the motility of unattached sperm during co-culture and fertilizing ability were assessed. In experiment 2, heparin treated sperm (hsp) or no treated sperm (nsp) were used to evaluate OEC binding ability of capacitated sperm. In experiment 1, regardless of their origin, approximately 65% of the sperm were attached to OEC within 2h. From 6h of co-culture, the numbers of unattached sperm on ampullary OEC were significantly higher than those on isthmic OEC (p<0.005). From 12h of co-culture, the motility of unattached sperm on isthmic OEC were significantly higher than those on ampullary OEC(p<0.05). The cleavage rate of oocytes inseminated on OEC derived from isthmic segment was also significantly higher than those from ampullary segment (p<0.01). In experiment 2, the numbers of unattached hsp on OEC were significantly higher than those of controls (p<0.01), between 2-24h examination. From 12h of co-culture, the motility of unattached nsp were significantly greater than those of hsp (p<0.01). These results show that bovine OEC derived from the isthmus play more important role(s) for sperm binding, maintaining motility and fertilization in vitro than those from the ampulla, and heparin induced capacitation may change sperm binding ability on OEC in vitro.

Objective: Common reed (Phragmites communis Trin.) could potentially provide an alternative resource for silage; however, its silage quality is poor. The aim of this study was to investigate the factors in reed that contribute to poor quality and determine how the use of additives at ensiling could improve fermentation quality. Methods: In Experiment 1, we determined the chemical composition and the presence of indigenous lactic acid bacteria (LAB) in reed. We further examined fermentation quality of reed silage under conditions without additives (NA) and treated glucose (G), lactic acid bacteria (L), and their combination (G+L). In Experiment 2, silage of NA, and with an addition of cellulase and lactic acid bacteria (CL) were prepared from harvested reed. The harvested reeds were fertilized at nitrogen concentrations of 0, 4, 8, and $12g\;N/m^2$ and were harvested thrice within one year. Results: The indigenous LAB and fermentable carbohydrates are at extremely low concentrations in reed. Reed silage, to which we added G+L, provided the highest quality silage among treatments in Experiment 1. In Experiment 2, N fertilization had no negative effect on silage quality of reed. The harvest times decreased fermentable carbohydrate content in reed. The CL treatment provided a higher lactic acid content compared to the NA treatment. However, the quality of CL treated silage at the second and third harvests was significantly lower than at the first harvest, due to a reduction in carbohydrates caused by frequent harvesting. Conclusion: The causes of poor quality in reed silage are its lack of indigenous LAB and fermentable carbohydrates and its high moisture content. In addition, reed managed by frequent harvesting reduces carbohydrate content. Although the silage quality could be improved by adding CL, higher-quality silage could be prepared by adding fermentable carbohydrates, such as glucose (rather than adding cellulases).

The aim of this study was to investigate the efficacy of Lactobacillus spp. W44 and J124 strain isolated from Kimchi on the growth rate, average daily gain (ADG), feed conversion and change of intestine microflora in the weaning piglets. In the experiment 1, growth rate was significantly increased to $28.5\;{\pm}\;4.3\;kg$ and $27.6\;{\pm}\;3.3\;kg$ after oral administration of W44 and J124 strain as feed additives, respectively (p<0.05). ADG and feed conversion were also significantly improved after administration during 44 experiment days (p<0.05). In the analysis of intestinal microflora, the number of Lactobacillus spp. in the experiment groups was significantly increased 100 to 1,000 times compared to those of control group. In the experiment 2, the efficacy of W44 and J124 strains on the growth rate, ADG, feed conversion and change of intestine microflora were reconfirmed significantly (p<0.05). However, there were no significant differences on feed conversion in the W44 bead and J124 bead groups. In summary, our results suggest that W-44 and J-124 stains from Kimchi have a significant effect on the weight gain and feed conversion, and it may be useful probiotic strains for the weaning piglets as feed additives.

Philip Roth rejects the narrative unity and singularity of the traditional novel and creates instead a multi-levelled, fragmentary, and repetitive narrative. It is not easy to distinguish fact from fiction in The Plot Against America. As an entertaining and creative work of the postmodern historiographic metafiction, Philip Roth's The Plot Against America interrogates the existence of historically verifiable facts, the validity of authentic and official version of history, and reexamines the narrative conventions of history writing. The aim of this paper is to examine Roth's narrative experiment or 'thought experiment' and to explore the intention of creating alternative history in The Plot Against America. Roth does a 'thought experiment' in The Plot Against America. In this cautionary "what if" political fable, Roth hypothesizes that in 1940 aviation hero Charles Lindbergh, an ardent isolationist who was sympathetic to Hiltler, won the presidency. Jewish communities are stunned and terrified as America flirts with fascism and anti-semitism. Reimagining his children-with considerable fact mixed in with the fiction-Roth narrates an alternative history that has an unsettling plausibility. Roth has constructed a brilliantly telling and disturbing historical prism by which to refract the American psyche as it pertain to the discord of individual, race, history in The Plot Against America. Roth analyzes the life of individual in a historic space, the situation of anti-semitism in world of invisible order, racial conflict between black and white in world of visible order, and the darkest side of national power in this work. Roth's stories argue for the equality of various cultures grounded on the common notion of humanity, for an ethic of mutual respect, and for the peaceful resolution of conflicts.
