The objective of this study was to determine the effects of dietary supplementation of whole garlic powder (WGP) on semen characteristics and blood antioxidant level in boars. For this study, nine Duroc boars of 12 months age were used. Semen and blood samples were collected for 13 weeks, once in each week. The boars were fed the basal diet (BD; control) or BD supplemented with 3% WGP. There were no significant differences in the semen volume and sperm concentration between control and WGP group on all collection weeks. However, total sperm number per ejaculate was higher in the WGP group than that in the control group on collection weeks 6, 7 and 8 (P<0.05). Also, on collection weeks 5, 6, 7 and 8, mean of total ejaculated sperm numbers per boar were significantly higher in the WGP group compared to control group (P<0.05). On the other hand, ejaculation frequency per boar (boar's libido) and total ejaculated sperm number per boar were significantly increased in the WGP group compared to the control group, respectively (P<0.05). Although there was no difference in polyphenol level in seminal plasma between two treatment groups, polyphenol level in blood serum was significantly higher in the WGP group on collection weeks 9, 12 and 13 (P<0.05). These results indicate that dietary supplementation of 3% WGP improves boar libido and semen productivity such as ejaculation frequency per boar, total sperm number per ejaculate, mean of total ejaculated sperm number per head, and elevate the blood level of antioxidant (polyphenol) in boar serum.

This study was conducted to find out the effect of sexual education for knowledge and attitude toward sex are elementary school students.

The subjects were 500 male and female elementary students from the fifth and sixth grades of 4 public elementary schools in Pusan. The subjects were assigned to a experimental (250) and a control (250) group. The research tools were sex education program and consists of physiology(menache, ejaculation), psycological(pleasure of growth), sociological(hetero sexual relationship) are about set The sex education program was given to experimental group for 6 hours by the trained school nurse's lecture using slide film and OHP film. The data were obtained before and after the sex education. Data collection was done during the period betwen Feb. 3. 1997. to Feb. 20. 1997. The collected data were analyed using frequency, percentages, $X^2$-test, means, standard deviation, t-test, ANOVA, MANCOVA with SPSS program. The results were obtained as follows : 1. The first hypotheses attained that the experimental group(19.72) is higher than the control group(12.12) on the knowledge toward sex(F=467.30, P=.000). At the physical area, the experimental group(8.84) is higher than the control group(3.96) (F=687.39, P=.000). At the psychological area the experimental group (5.18) is higher than the control group(2.63) (F=411.66, P=.000). At the social area, the experimental group (5.70) is higher than the control group (5.54), this is not significant difference (F=.67, P=.413). 2. The second hypotheses attained that the experimental group(60.42) is higher than the control group(52.48) on the attitude toward sex(F=215.70, P=.000). At the physical area, the experimental group(23.10) is higher than the control group(20.68) (F=128.68, P=.000), At the psychological area, the experimental group(20.11) is higher than the control group(16.40) (F=108.64, P=.000). At the social area, the experimental group(17.22) is higher than the control group(16.00), this is area are significant differences (F=70.37, P=.000). 3. Knowledge toward sex according to sex, religon, atmosphere of family, mother age and educational background are significant differance (P<0.05). Attitude toward sex according to sex is significant differance (P<0.05).
