Honam Shear Zone is a mylonite zone approximately parallel to the NE-SW trend located southern part of Korea peninsula. Geologic ages and petrogenesis of foliated granites in this zone are as follows: Igneous rocks of this zone are composed of granite gneiss, Paleozoic granites, Songrim granites, Jurassic granites and Cretaceous granites. Foliated granites show deformed phase of Paleozoic and Songrim granites during Daebo Orogeny. And isotopic ages obtained from foliated granites are early Permian to late Triassic period (276~200 Ma). Most of foliated granite masses are igneous complex consisting of a series of differential product of cogenetic magma. The individual rock mass of foliated granites plotted on Harker diagram shows mostly similar trend of calc-alkali series. REE diagram indicates that LREE amount of foliated granites are more enriched than HREE and negative Eu anomalies of them are weaker than those of the other granites. From these data, we suggest the rocks are generated from continental margin under syntectonic environment. Original magma type of foliated granites correspond to I-type, syn-collision type and Hercyano type. In compressive stress field between Ogcheon folded belt and Youngnam massif, foliated granites had formed due to mylonitic deformation. Those facts indicate that magma of foliated granites would had been generated by melting in lower crust or contamination in upper mantle.

This experiment was carried out to investigate the renditions to maintain good post-thaw motility and viability of canine spermatozoa when the semen was frozen using methanol. The semen from two male dogs which had been proven to be fertile in the previous one year was treated with different compositions of semen diluent and was frozen at different freezing temperatures, When canine semen was frozen at-2$0^{\circ}C$, -6$0^{\circ}C$, or -8$0^{\circ}C$, the spermatozoa frozen and stored at -2$0^{\circ}C$ showed very low post-thaw motility and viability from day 2 to 7 and showed no viability since day 15 after freezing. The spermatozoa frozen and stored at -6$0^{\circ}C$ or -8$0^{\circ}C$ showed higher post-thaw motility and viability on day 2, 1, 15 and 30 after freezing than that frozen and stored at-2$0^{\circ}C$(p<0.01), with no difference between two groups. Among different composition groups of the semen diluents of control(tris + egg yolk + glycerol), egg yolk-free, 히ycerol-free, and tris-free, Prior to freezing, the egg yolk-free diluent showed significantly love. motility and viability than the other diluents(p<0.05). On each thawing day (from day 2 to 15 after freezing), control group showed considerably higher motility and viability than the other groups(p<0.01). The canine spermatozoa frozen and stored at -6$0^{\circ}C$ and -8$0^{\circ}C$ showed gradual decrease of motility from day 2 to 30 after freezing and the spermatozoa of these two groups thawed on day 30 showed considerably love. motility than those thawed on day 2 after freezing, respectively(p<0.01). These results indicate that the freezing temperature of either -6$0^{\circ}C$ or -8$0^{\circ}C$ can be applicable to the freezing method using methanol and also all of the components of the semen diluent including cryoprotectant, buffer and cold-shock buffer are very important to maintain motility and viability of canine spermatozoa in the freezing and thawing procedure.

In the present study, wogonin, a major flavone isolated from Scutellaria Radix were examined for its imunosuppressive activity on the 2,4-dinitro-fluorobenzene (DNFB)-induced delayed type hypersensitivity (DTH) in C3H/HeN mice. This compound inhibited selectively $TNF-\alpha$ and IL-4, but not IL-6, IL-10 and $IFN-\gamma$ on DNFB-induced Th1 and Th2 cytokines in a concentration-dependent manner. Interestingly, this compound increased the expression of heme oxygenase-1 (HO-1) in a concentration-dependent manner The above results reveal that wogonin possesses anti-inflammatory, humoral and cellular immunomodulatory, and stress reducing activities on the DNFB-induced DTH in mice and these properties may contribute to the anti-atopic dermatitis activity of Scutellaria Radix.
$CD4^+$ Jurkat T 세포주에서 Th1과 Th2 사이토가인 조절에 미치는 황금 유래 Baicalin, Baicalein 및 Wogonin의 효과

In the present study, baicalin, baicalein, and wogonin, a major flavone isolated from Scutellaria Radix were examined for their effects on PMA-induced Interlukin-6 (IL-6), $interferon-\gamma(IFN-\gamma)$, tumor necrosis factor $(TNF)-\alpha$, IL-4, IL-10, and IL-13 productions in the PMA-stimulated $CD4^+$ Jurkat T cells. These three compounds inhibited PMA-induced Th1 cytokine $(IL-6,\;IFN-\gamma,\;TNF-\alpha)$ and Th2 cytokine (IL-4 and IL-13) productions in a concentration-dependent manner. But wogonin, but not baicalin baicalein, increased PMA-induced IL-10 production. These results suggest that baicalin, baicalein, and wogonin, a major flavone modulate Th1 and Th2 cytokine productions in $CD4^+$ Jurkat T cells and these properties may contribute to the anti-atopic dermatitis activity of Scutellaria Radix.

The main aspect of this study are to clarify igneous activity of igneous rocks, which is a member of various intrusives and volcanics exposed in Naju-Namchang area of southern central zone of Ogcheon Geosynclinal Belt, southern part of Youngdong-Kwangju depression zone of tectonic provinces in Korea. Naju-Namchang area are subdivided into three rock belts based on occuring of Cretaceous granites. Three rock belts consist of foliated granites, Jurassic granites and Cretaceous granites in central granitic rock belt (C-C), and acidic tuff and lavas in northwest volcanic rock belt(C-NW) and southeast volcanic rock belt(C-SE). Chemical composition of these igneous rocks show mostly similar trend to the Daly's values on Harker diagram and correspond to VAG + Syn-COLG region on Pearce's discrimination diagram. These igneous rocks vary wide range in total REE amount(37.4-221.3ppm) characterized by enriched LREE content and steep negative slope in Eu(-) anomaly. It is concluded each synchronous granites which composed of serveral rock facies is considered to formed by differentiation of co-magma at continental margin, and igneous activity of study area are two more Pre-Cambrian Orogenies, Songrim Disturbance, Daebo Orogeny and Bulkuksa Disturbance.

The semen from four male dogs which had been proven to be fertile in the past were frozen in a deep freezer at $-60^{\circ}C$ by simple freezing method using methanol and preserved at the same teperature for from 7 to 10 days. The semen were inseminated to 7 female dogs in estrus to find out the usability of this freezing method in artificial insemination for dogs. In addition, post-thaw motility and viability of sperm from two male dogs which had been fertile were also evaluated to investigate individual difference. Successful pregnancy was obtained by artificial insemination with canine semen frozen at $-60^{\circ}C$ by simple freezing method using methanol, namely, 3 bitches among 7 bitches which had been inseminated delivered puppies(42.8%). The average litter size of the whelping dogs were 4.3 puppies. The average post-thaw motility of canine sperm in the cases of conception was showen higher than those of non-conception(65.0% vs. 42.5%), along with the, same result in the average post-thaw viability between the two groups(53.3% vs, 27.5%). Individual difference of post-thaw motility and viability was obtained between two fertile dogs(p<0.05).

Devonian Geochang foliated granite and Jurassic plutonic rocks intrude Precambrian metamorphic Complex at Geochang area, southern part of the Korean Peninsular. Among them hornblendes from four Jurassic plutonic bodies which have had no trace of metamorphism or deformation since their intrusion were dated by K-Ar method. Hornblende gabbro dike which intruded Anorthosite of unknown age revealed $204{\pm}10Ma$, and hornblende granite and hornblende-biotite granodiorite were $178{\pm}9Ma$ and $181{\pm}9Ma$, repectively. Also, hornblende diorite which partly showing primary foliations were $178{\pm}9Ma$, so igneous activity of Geochang area, northern part of Jirisan, were active about 180 Ma before. Microprobe data of dated hornblends and other major constituent minerals such as plagioclases and biotites were also reported, and their chemical composition showed systematic changes in terms of lithologic types.

This study aims to examine the relationships between sub-factors of stress response level and perceived well-being according to the participation of sports activities. Total of 921 suspects that including 613 sports activity participants, 308 non-participantsare collected. and Responded on guestionaires.The statistical data analyses such as factor analysis and Cronbach's test to check validity and reliability in turn Frequency analysis and descriptive analysis to find out individual characteristics. In addition, t-test, correlation analysis, and multiple regression analysis are used to hypothesis testing.SPSSWIN Ver 12.0 is used and all the statistical significance level is set to α=.05.As a result, the conclusions of the study are summarized as followings.First, sports activity participants show lower level than sports non-participants to all the stress sub-factors such as fatigue, aggression, anger, socialization, depression, frustration, and tension.Second, sports activity participants shows higher perceived well-being than non-participants.Third,sports activity participants decrease the perceived well-being with stresses from sub-factors such as fatigue, depression, frustration, and tension are higher. It tells that a counter measure is necessary for this case.Fourth, non-participants decrease the perceived well-being with stresses from sub-factors such as fatigue, depression, and tension are higher.When these conclusions are generalized, regular exercise lowers stress response level and increases perceived well-being. In addition, stress is turned out to be a factor that negatively affects perceived well-being.

This research reviews the characteristics of earth pressure incurred by GRS-RW mainly used in the railroad design in order to resist large lateral load caused by train and additional load induced by facilities such as noise barrier fences, electric poles, etc. The results of test shows the existence of arching effect that horizontal earth pressure increases in the backfill while earth pressure applying to the wall reduced under GRS-RW system. In both cases, unreinforced wall and GRS-RW system, the coefficient of earth pressure (K) is about 0.4 at the rest. However, after lateral displacement occurs, the earth pressure nearly reduce down to zero under GRS-RW system while the earth pressure decreases up to 0.12 in case of unreinforced retaining wall.
