This study was carried out to investigate the effects of imported pellet frozen semen on sperm motility and NAR acrosomes after thawing, and the farrowing rates, litter sizes and preweaning body weights after artificial insemination. A total of 28 sows of Landrace, Large White and Duroc were inseminated at the Chungnam Provincial Animal Breeding Station. The results obtained are summarized as follows: 1. Landrace andLarge White had higher sperm motility than Duroc by about 20% and had higher NAR acrosomes by about 10%. 2. The farrowing rates of Landrace, Large White and Duroc were 63.6, 55.6 adn 50.0%, respectively. The number of pigs born alive per litter were larger in Landrace and Large White as compared with Duroc (p<.01). 3. Duroc had the highest mean pig weight at birth, followed by Landrace and Large White (p<.01). The mean pig weights at 21 days and 56 days had no significant differences between the breeds.

This study was carried out to investigate a point of difference between normal and inferior Korean red ginseng (Naeback red ginseng = red ginseng with white part of clear boundary in phloem and/or xylem of ginseng body, saengnaeback red ginseng red ginseng with white part of indistinct boundary). White part with clear or indistinct boundary in center of ginseng body was observed in inferior red ginseng (naeback and saengnaeback red ginseng), and the differences in the internal color intensity was also found with naked eye. In hunter color values of normal and inferior parts of red ginseng in accordance with particle size, L value was increased with a diminishment in particle size, while a and b value were decreased. Absorbance at visible spectrum did not differ from water and 70% ethanol extract from normal and inferior parts of red ginseng, but absorbance in UV spectrum of extract from naeback part showed higher than those of normal and saengnaeback part. In comparison of intrastructure by electron microscope, the horizontal and vertical section of cortex and pith layer from normal part showed the very dense state, but small holes were found in naeback part of red ginseng by naked eye and electron microscope. The specific surface area of normal, naeback and saengnaeback part appeared 3.02, 3.33 and 6.55 ㎡/g, respectively. From above results, we consider saengnaeback red ginseng is red ginseng in the intermediate process which normal red ginseng changes to naeback red ginseng.

The effects of white bread supplemented with konjac glucomannan on diet-induced obesity in rats were investigated. Four groups of male Sprague-Dawley rats were examined: a non-obese control group (NC), an obese high fat diet group (HF), an obese high fat diet group given bread supplemented with 10% konjac glucomannan (KGM1) and an obese high fat diet group given bread supplemented with 20% konjac glucomannan (KGM2). The daily weight gain of the KGM1 group increased slightly and decreased in the KGM2 group compared to the HF group. The serum triglycerides, total lipid, total cholesterol, and HDL-cholesterol increased in the HF compared to the NC group, whereas they decreased in KGM1 and KGM2 groups. After having this experimental diet for 6 weeks, the body weight in KGM1 and KGM2 groups decreased compared to the HF group. While the initial R$\ddot{o}$hrer index was 23.13 in the NC group, and 31.50~32.59 in the HF, KGM1, and KGM2 groups, the index after the experimental diets for 6 weeks was 28.39 in the NC group, 36.88 in the HF group, 33.48 in the KGM1 group and 29.64 in the KGM2 group. The level of body fat increased from 1% to 7.14% in the NC group, from 15.60% to 60.05% in the HF group, and from 10.60% to 10.83% in the KMG1 group, but decreased from 10.45% to 8.20% in the KGM2 group. These results demonstrate that white bread with glucomannan is effective in reducing body weight and serum lipids in high fat diet-induced obese rats.

Many critics on William Faulkner's As I Lay Dying have read Addie Bundren as the disrupter of patriarchal power. By raising a question about the usefulness of language, which is the symbolic power of patriarchy and having an affair with the preacher Whitfield outside her wedlock, Addie directly challenges patriarchal power. From a quite different vantage point, however, we can read Addie as the faithful protector of the norm of whiteness in the South in light of the social hierarchy. As a former school teacher, Addie is from middle class before her marriage. By her marriage to Anse, who is a lower-class white, Addie has class anxiety that her social status in the stratum of whiteness could be degraded from a middle to a lower-class white, "white trash," which means that she is not white enough to be considered as the normative whiteness. Especially, Addie's anxiety increases due to the fact that her lazy husband is reluctant to work and relies on her neighbors, causing her family to be entrapped at the bottom in the stratum of whiteness. Therefore, she decides to take revenge on her husband after giving birth to her second child Darl by asking Anse to bury her dead body in her familial burial site in Jefferson. By rendering her family to suffer the hardship during her funeral procession, not only does she succeed in taking revenge on Anse on the surface, she regains her social status as a middle-class white by being buried in Jefferson fundamentally.

White-skinned sweet potato (Ipomoea batatas L.) has been traditionally used for diabetes treatment and management in many countries. In this experiment, methanol extract of white-skinned sweet potato (WSPMe) at a dose of 100 or 200 mg/kg body weight was tested to evaluate its effect on renal damage in streptozotocin (STZ)-induced diabetic rats. Its efficacy was compared with that of insulin secretogogue, glimepiride ($50\;{\mu}g/kg$ body weight). Experimental diabetes was induced by a single dose of STZ (45 mg/kg, i.p.) injection. The WSPMe and glimepiride were administered orally for 14 days and the effects on glucose, renal markers including blood urea nitrogen (BUN), creatinine and lactate dehydrogenase (LDH), lipid peroxide (LPO) level, antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathion-S-transferase (GST) activities in kidney were studied. An increase in BUN, creatinine, LDH, glucose, LPO levels and decrease in SOD, CAT, GPx and GST features were observed in diabetic control rats. Administration of WSPMe at a dose of 200 mg/kg body weight caused a significant improvement in blood glucose, LPO level, renal markers, lipid peroxidation markers and increased antioxidant levels in diabetic kidney. In conclusion, the WSPMe was found to be effective in reducing oxidative stress, thus confirming the ethnopharmacological use of I. batatas L. in protecting diabetes and its complications.

The purpose of this study is to analyze the aesthetic characteristics of grotesque images in fashion specially focused on the postmodern grotesque with the relationship between body and fashion. The results are as follows: The postmodern grotesque fashion images in the years of 1990-2000 can be analyzed as trans-stylistic, trans-boundaries which have been set by the modem western white elite men group. The postmodern grotesque fashion images in the years of 1990-2000 can be categorized as 1) unclear boundaries between genders: body and dress; human being and non-human being; life and death; wholeness and fragmentation; clear body and abject body. 2) violence to the body: body mutation by simplification, exaggeration; body injury.

Decoys for automatic jigging machines, the body part of a squid hook, have been developed in small and existing sizes in consideration of squid food, color blindness, and retinomotor responses and in utilization of pearl pigment, PP of high transparency, and combined mixture. In comparison of the developed silver-white decoy and existing decoys, the optical characteristics were examined, and the fishing performance of small size silver-white squid hooks was assessed in application of 4 fishing boats with the squid automatic jigging machine and metal halide fishing lamp in July, 2012. The luminances of the three squid hook colors-green, dark green and silver-white-increased as the intensity of illumination increased. Among these, the increase of silver-white was particularly distinguished. As to the average contrast of squid hooks, that of silver-white was 10.33, which was the highest, and then green 1.86 and dark green -0.10 in the order. As to the fishing performance of the silver-white hook, that of the 202 Geumyeong-ho and 101Yongjin-ho which caught squids were similar to that of the existing green hook and was relatively low in the case of the Dongbu-ho. However, that of the Haengbok-ho which caught relatively small squids whose average length was 19.9cm and installed silver-white hook in all automatic jigging machines was significantly excellent. In order to enhance the fishing performance of small size silver-white hooks, therefore, it would be effective to install in every automatic jigging machines of fishing boat and to start fishing before July by which small squids are caught.

Objectives: The purpose of this study was to investigate the anti-obesity effects of the aqueous extract of Schizandra chinensis (SC) in menopausal mice. Methods: To induce menopausal obesity, female mice were ovariectomized (OVX) and fed a high-fat diet (HFD; 60% fat, 28% carbohydrates, 14% protein) for 12 weeks. The mice were divided into 6 groups (n = 8): NOR (sham-operated and vehicle-treated), HFD+OVX (vehicle-treated), E2 (17-beta estradiol 50 ㎍/kg-treated), SC1 (1 mg/kg SC-treated), SC10 (10 mg/kg SC-treated), and SC100 (100 mg/kg SC-treated). Samples were orally administered for 6 weeks, after which all experimental mice were sacrificed. Body weight, feeding efficiency, white adipose tissue weight, adipocyte diameter, and fat vacuoles in liver were analyzed. Results: By treating with SC extract, the body weight and feeding efficiency of mice were significantly decreased. The weight of visceral fat tissues was decreased in the SC10 and SC100 groups. Histopathology showed that fat cell diameters of white adipose tissue were also decreased in the SC10 and SC100 groups. Additionally, SC extract regenerated the hepatocyte damage and decreased the size and number of follicular adipocytes Conclusion: In summary, these results suggest that SC has inhibitory effects against menopausal obesity. Schizandra chinensis may be a potential alternative for obesity among female menopausal diseases.

The readability and the visuability are very significant when the letters or figures are displayed as static visual information. Not only is the beauty of the body type character(small letters) important but the display type character(large letters) should also be read easily, quickly and precisely. The issue regarding the readability in terms of perception of information has been raised continuously for all kinds of small signage and billboard, etc., which are written in display type within our everyday life. Among the various kinds of small signage and billboards the car licence plate is well known. Among all the possible factors that would have made an impact on the readability of licence plate, this paper focused on the effects of arrangement of character(letters and figures) and contrast of colors for the readability of licence plate using the within-subject analysis. The statistical analysis results in error reading rate, the character arrangement were significant but the color contrast(green/white, white/green, blue/white, white/blue, black/yellow) was not, No interaction was found.

In this paper, we propose the modified display color control system using white point line, boundary lines and S-shaped curves to emphasize blue and red tone colors on CIE1931 diagram. The proposed system divides RGB gamut into movable area and non-movable area by using boundary lines. The colors in movable area are moved into right side or left side along quadratic curve to change the bluish (or reddish) color to more bluish (or more reddish), while those in non-movable area are excepted from color control to prevent skin color from changing. The loci of the quadratic curves are very similar to the arc of the white-point line which connects all points that represent the chromaticities of a black body radiator at different temperatures and is also called the black body locus. The RGB gamut extension by movement of chromaticity coordinate can improve color reproducibility. Therefore in the case of application to LCD, the display shows excellent performance because the LCD's color reproducibility is comparatively lower than that of other display systems. The proposed system is also experimentally demonstrated with Xilinx Virtex FPGA XCV2000E- 6BG560 and the TV set.
