The purposes of this study were intended to examine by variables influencing gender equality consciousness in middle school students and provide basic materials useful for their education of gender equality consciousness by finding out variables influencing equality consciousness. The subjects were the 1,201 students who studied at middle schools in Jeonllabuk-do. Using structured questionnaire surveyed. Data were analyzed with Frequency, Percentage, Mean, Std, Cronbach's ${\alpha}$, t-test, and Multiple Regression using SPSS/PC WIN 14.0 program. The major findings were as follows: 1. The mean value of gender equality consciousness in middle school students was 3.89 in the whole, 3.88 in home life, 3.92 in school life, 4.04 in the workplace, and 3.70 in social and cultural life, suggesting high value in all areas. While the workplace and the school life showed higher gender equality consciousness than the whole, the home life and social and cultural life showed lower consciousness. 2. The whole gender equality consciousness were influenced by sex, mother's gender equality consciousness, homeroom teacher's gender equality consciousness, an enough schooling, desirable school types, perception of abolition of family-head system, and social gender equality consciousness. And the Middle school students' whole gender equality consciousness were explained about 32% by these variables.

Prickly pear cactus cladodes were extracted with hot water and 70% ethanol, followed by fractionation with n-hexane (HF), ethyl acetate (EF), n-butanol (BF), and distilled water. Total phenolics and total flavonoid contents as well as antioxidative and anti-inflammatory activities were then measured. Total phenolic contents were 784, 452, and 220 mg gallic acid equivalents (GAE)/g, whereas total flavonoid contents were 214, 76, and 113 mg quercetin equivalents (QE)/g in EF, BF, and HF, respectively. DPPH and ABTS radical scavenging activities ($IC_{50}$) were 103 and $105{\mu}g/mL$ in EF, 359 and $379{\mu}g/mL$ in BF, and 469 and $605{\mu}g/mL$ in HF, respectively. Oxygen radical absorbance capacity was highest at $391{\mu}M$ TE in EF (in decreasing order of $117{\mu}M$ TE in BF and $64{\mu}M$ TE in HF), whereas superoxide anion radical scavenging activity ($IC_{50}$) was highest at $40{\mu}g/mL$ in EF (in decreasing order of $69{\mu}g/mL$ in BF and $98{\mu}g/mL$ in 70% ethanol extract). Inhibitory activity ($IC_{50}$) of nitric oxide (NO) production induced by LPS-activated RAW264.7 cells was highest at $62{\mu}g/mL$ in HF (in decreasing order of $104{\mu}g/mL$ in EF and $465{\mu}g/mL$ in BF). The selectivity index (ratio of inhibitory activity of NO production to cell cytotoxicity) was highest at 4.63 in EF (in decreasing order of 3.37 in HF and 2.14 in BF). In conclusion, EF showed potent antioxidant and anti-inflammatory effects with high phenolic and flavonoid contents.
We report on two cases of pericentric inversion of X chromosome. The cases were found in a 40-year-old man with azoospermia and in a family of a 38-year-old pregnant woman. The first case with 46,Y,inv(X)(p22.1q27) had concentrations of LH, prolactin, estradiol, and testosterone that were within normal ranges; however, FSH levels were elevated. Testis biopsy revealed maturation arrest at the primary and secondary spermatocytes without spermatozoa. There were no microdeletions in the 6 loci of chromosome Y. For the second case, the cytogenetic study of thepregnant woman referring for advanced maternal age and a family history of inversion X chromosome was 46,X,inv(X)(p22.11q27.2). The karyotype of her fetus was 46,X,inv(X)(p22.1q27). Among other family members, the karyotypes of an older sister in pregnancy and her fetus were 46,X,inv(X)(p22.11q27.2), and 46,Y,?inv(X), respectively. The proband's father was 46,Y,inv(X)(p22.11q27.2). All carriers in the family discussed above were fertile and phenotypically normal. In addition, the ratio of inactivation of inv(X) by RBG-banding was discordant between the two sisters, with the older sister having only 4.1% of cells carrying inactivated inv(X) while the proband had a 69.5% incidence of late replicating inv(X). Therefore, we suggest that the cause of azoospermia in the first case might be related to inversion X chromosome with positional effect. Also, the family of the second case showing normal phenotype of the balanced inv(X) might be not affected any positional effect of genes.
The infestation rates and abundances of human infecting metacercariae (Clonorchis sinensis, Metcgonimus spry. , Centrocestus crmatus, Echinostoma hortense, Echinochusnus japonicw, Clinostomum complanctum) in freshwater fish were investigated at the three river areas - Taewhagang (river), Hyongsangang (river), Nakdonggang (river) - in Kyongsang-do and at four streams - Yonpungchon, Munsanchon, Kyonganchon, and Konjiamchon- in Kyonggi-do, Korea in 1994-1995. The fish caught at Taewhagang were heavily infested with metacercariae of Clonorchis sinensis and Centrocestw armctus. At Hyongsangang, Zncco platypus and Z. temmincki were moderately infested with metacercariae of C. crmctus. Chomanpo, at the basin of Nakdonggang, was still endemic for C. sinensis. In the fish caught at four streams of Kyonggi-do, metacercariae of C. sinensis exhibited the highest infestation rate and intensity out of 6 species of metacercariae. The infestation intensity of C. sinensis metacercariae in fish flesh was markedly different according to each division of flesh. The cause of this difference was conjectured as a result of larval behavior. The metacercariae of C. omnt5 were found in almost all parts, except scales and fins, of fish. The infestation rates and intensities of C. sinensis and C. armntus metacercariae in Taewhagang greatly increased as compared with those of previous reports . RhinoBobius bmnneus and Aconthorhone5 macropterus are newly recorded intermediate hosts of Echinostonn hortense. The reason of large differences from previous data was discussed and the standard method of metacercaria examination was proposed.

This study was conducted to investigate the effects of mud flat bacteria origin protease supplementation by crude protein level on growth performance, nutrient digestibility, total protein and BUN (blood urea nitrogen) concentration in broilers. A total of four hundred eighty broilers were randomly allocated into four treatments with six replications for five weeks. Dietary treatments included 1) high crude protein diet, 2) high crude protein diet + 0.1% protease, 3) low crude protein diet and 4) low crude protein diet + 0.1% protease. During the entire experimental period, weight gain and feed/gain were improved in treatments of high crude protein diets and low crude protein diet added protease compared with treatment of low crude protein diet without protease (P<0.05). Similarly, DM digestibility was also improved in treatments of high crude protein diets and low crude protein diet added protease compared with treatment of low crude protein diet without protease (P<0.05). N digestibility was improved in treatment of high crude protein diet added protease compared with low crude protein diet without protease (P<0.05). Total protein concentration in blood was increased in treatment of high crude protein diet without protease compared with other treatments (P<0.05). In conclusion, mud flat origin protease was effective in improving weight gain, feed/gain and nutrient digestibility, and influenced blood total protein in broilers.
Purpose : The aim of this study was to compare the clinical effects of modified porcine (Curosurf$^{(R)}$) and bovine (Newfactan$^{(R)}$) surfactants in the treatment of neonatal respiratory distress syndrome. Methods : Between April 2004 and December 2006, 65 neonates (birth weight ${\leq}$2,500 g and gestational age ${\leq}$35 weeks) with neonatal respiratory distress syndrome were treated in our neonatal intensive care unit with surfactant. Thirty-one neonates received Curosurf$^{(R)}$ and 34 neonates received Newfactan$^{(R)}$. The neonates were not enrolled if they had major congenital anomalies or meconium aspiration syndrome. We compared the changes in respiratory parameters after surfactant instillation, the incidences of acute and chronic complications, and the mortality between the two treatment groups. Results : Neonatal and maternal demographic characteristics were not different between the groups. The patterns of change in the respiratory parameters after surfactant instillation were not statistically different between the groups. The incidences of surfactant reinstillation and acute complications, such as pneumothorax, patent ductus arteriosus, pulmonary hemorrhage, and grade 3-4 intraventricular hemorrhage, were not different between the neonates who received Curosurf$^{(R)}$ and the neonates who received Newfactan$^{(R)}$. There were no statistically significant differences in the duration of mechanical ventilation, oxygen therapy, hospitalization, prevalence of bronchopulmonary dysplasia, periventricular leukomalacia, retinopathy of prematurity, necrotizing enterocolitis, and mortality between the groups. Conclusion : In the present comparative study, no significant differences in the clinical effects of Curosurf$^{(R)}$ and Newfactan$^{(R)}$ were observed.
Bacteriostatic activity of secretory immumoglobulin A (SIgA) in human and bovine colostrums on enterotoxigenic type Salmonella was tested in the tissue culture medium. SIgA was used in $0.1{\sim}5.0mg/m{\ell}$ concentration with or without the addition of egg lysozyme tested for theirs bacteriostatic activites. 1. Bovine SIgA rich fraction with a large amount of $IgG_1$-dimer could be prepared from bovine colostrum of Holstein cows by anion exchange chromatography using DEAE-Sephadex A-50 and gel filtration on Sephadex G-200 and Sepharose 6B. 2. Human SIgA appeared to be the most bacteriostatic effect for all varieties of Salmonella in a range of $0.5{\sim}1.0mg/m{\ell}$ Bovine SIgA showed a marked bacteriostatic effect increased by increasing the concentration. Bovine IgG had not show bacteriostatic effect against both enterotoxigenic type Salmonella. Egg lysozyme as well as bovine SIgA also showed a marked bacteriostatic effect increased by increasing the concentration. 3. When the growth inhibition of human SIgA was tested by adding egg lysozyme with time interval, egg lysozyme showed bacteriostatic effect as compared with control. But human SIgA and adding with lysozyme showed slight the bacteriostatic effect. 4. When the growth inhibition of bovine SIgA was tested by adding egg lysozyme with time interval, all treatment against S. enteritidis showed bacteriostatic effect as compared with control In the case of S. typhinwrium, egg lysozyme showed a marked bacteriostatic effect as compared with control.
Visual media are taken the highest position in modem society, Modern poems also have been changed into visual poems, This aspect is the result of considering only individual talents ignoring traditions. Now, new Sigo should be concentrated on the mythological and historical voice from true nature and the body of human being, That is. ut should be converted into an ecological world view resolutely and restored a form of expression granted specific characteristics of our language. Advantages the computer media have brought. that is. equality freedom. human rights. harmony. pro-environmental value. can be maximized by positively accepting an ecological world view of Sijo which had included daily lives and spirits of the nation. Moreover. these all changes of new Sijo have to be established and recreated in the traditional expressions of Sijo. Aesthetic value of Sijo should be found in the expression forms such as phonetic harmony, rules of versification, rhythm, and etc. Then, we can overcome modern society's pathological phenomena such as severance, separation, dissolution, estrangement, psychiatric syndrome and etc. which visual media superiority brought. At the same time. it will cure ills of modern poems, Sijo and writing epochally and can establish true happiness and development.

Safflower red colorants extracted by two solvents including the traditional ash solution and $K_{2}CO_{3}$ solution was used for dyeing cotton, ramie, viscose rayon, silk, wool, and nylon fabrics. The effects of extraction solvents on the reflectance, K/S value, and color properties of the dyed fabrics were investigated. Wash/dry cleaning and light colorfastness were evaluated. Reflectance curves of cotton, ramie, viscose rayon, and silk fabrics dyed with red colorants extracted by $K_{2}CO_{3}$ solution were similar, showing the maximum absorption at 520nm, to that of the dyed fabrics with red colorants extracted by ash solution. The reflectance curves of wool and nylon fabrics were different, showing the maximum absorption at 400nm. K/S values of dyed fabrics with red colorants extracted by $K_{2}CO_{3}$ solution were higher than that by ash solution with the exception of nylon. $L^{*},\;a^{*},\;b^{*}$, and $C^{*}$ of the dyed fabrics with red colorants extracted by $K_{2}CO_{3}$ solution were higher than that by ash solution except for $L^{*}$ of nylon and $b^{*}$ of viscose rayon. Color difference(${{\Delta}E}^*$) of the dyed fabrics between ash solution and $K_{2}CO_{3}$ solution increased in the order named as cotton, silk, ramie, viscose rayon, wool, and nylon. Regardless of extraction solvents, safflower red colorants produced RP color on cotton, ramie, and nylon, R color on viscose rayon and silk, and YR color on wool. Wash/dry cleaning fastness of the dyed fabrics was high above 3/4 rating but light fastness was very poor. It is considered that the use of $K_{2}CO_{3}$ solution instead of the traditional ash solution would be more effective in terms of color reproducibility and extraction process.

Objectives : This study aimed to find out whether acupuncture at various acupoints shows any effects on appetite by regulating neurotransmitters in the hypothalamus through the expression of NPY and LR in the PVN via immunohistochemistry. Methods : Male Sprague-Dawley rats were divided into eight groups of five mice each. The rats in the acupuncture groups were treated with acupuncture at respective acupoints, twice per a day for 3 days. The animals were sacrificed 72 h after commencement of the experiment, the brains being dissected into serial coronal sections. Expressions of neuropeptide Y and leptin receptor in the hypothalamus were assessed by immunohistochemistry. Results : NPY expression in the PVN was enhanced and LR expression in the PVN was decreased by food deprivation. NPY immunoreactivity in the PVN of the food-derived rats was decreased by acupuncture at the auricular acupoint, Zusanli-acupoint, a and non-acupoint. However, acupuncture at the auricular acupoint showed most potent suppressing effect on NPY expression in the PVN of food-deprived rats. LR expression in the PVN decreased following food deprivation, and auricular acupuncture increased LR expression in the PVN of food-deprived rats. In normal conditions (fed state), LR expression in the PVN was not changed by acupuncture treatment at several sites. Conclusions : From this study, we have shown that acupuncture at the auricular acupoint exerts the most potent appetite suppressing effect on the food restriction state.
