This study was conducted to investigate the genetic diversity and genetic taxonomic relationships between Korean native black goat (KNBG) populations and crossbred goats. The 45,658 common single nucleotide polymorphisms present in the KNBG strain and crossbred goat were used for the analysis. The expected and observed heterozygosity (which can be indicators of genetic diversity) were in the order of crossbred, Gyeongsang National University, Jangsu, then the Tongyeong strains. The variance component represents the degree of genetic diversity between groups. The highest variance (19.98 %) was between the Dangjin and Gyeongsang National University strains. The lowest variance (8.87 %) was between the Jangsu and Tongyeong strains. In addition, the genetic distance between the populations showed that Jangsu and Tongyeong formed one branch (they were very similar genetically). The Dangjin and the Gyeongsang National University strains appeared to form a second branch. Furthermore, the crossbred formed one branch with the Dangjin and the Gyeongsang National University strains. Therefore, the results of this study can be used as basic data to reduce unnecessary inbreeding and genetic resource flow between the KNBG populations. The basic data indicates the uniqueness of the genetic resources of the domestic lineage. These findings provide a basis for differentiating KNBG and Crossbred goats to use to improve the desirable characteristics of this species.

We studied the development of schizandrin as a marker compound in Jangsu Omija. Schizandrin was validated for its LOD (limit of detection), LOQ (limit of quantitation), precision, accuracy, and recovery by HPLC relative to Omija powder. It showed a high linearity in the calibration curve with a coefficient of correlation ($R^2$) of 0.9990. The LOD and LOQ were 0.2 ${\mu}g/mL$ and 0.5 ${\mu}g/mL$, respectively. The intra- and inter-day precision of schizandrin calibration standards was 0.06~0.66% and 0.13~1.19%, respectively, and the intra- and inter-day accuracy of schizandrin was 98.35~103.30% and 98.35~103.00%, respectively. Overall, schizandrin was validated through our analytical methods as a marker compound in Jangsu Omija.

Novel Phellinus linteus HN1009K (HK1009) has been characterized on speedy mycelial growth and yearly artificial cultivation. In this study, antioxidant and anti-inflammatory activities of ethanol extract from mycelium and fruiting body of P. linteus HN1009K (HK1009) were compared to those of P. linteus (PL, Korea Sangwhang) and P. baumii (PB, Jangsu Sanghwang) as controls. HK1009 extract showed higher DPPH free radical scavenging activity in both mycelial and fruiting body samples than those of PL and PB. However, in xanthine oxidase assay, antioxidant effect was highly measured on mycelial samples of PL and HK1009. Mycelial extract of HK1009 induced high inhibitory effect on LPS-induced nitric oxide (NO) production in RAW264.7 cells comparing to PL and PB without toxicity on the cells. The results suggest that P. linteus HN1009K possesses superior antioxidant activity and anti-inflammatory effects.

The fruiting bodies of Sanghwang mushrooms, Phellinus linteus HN1009K (PLH) and Phellinus linteus (Korea Sanghwang, PLK), and Phellinus baumii (Jangsu Sangwhang, PB), were extracted with 70% methanol. The methanolic extracts of different concentrations ($5-200{\mu}g/ml$) showed inhibitory effects of 20-95% on plated aggregation induced by collagen (2.5 ug/ml), ADP (10 uM), and thrombin (0.1 U/ml). The PLH, PLK, and PB extracts (200 ug/ml) reduced ATP release from ADP-activated platelets by 50-60%. These results suggest that the methanolic extracts from Sanghwang mushrooms inhibit platelet aggregation.

A 10-year-old Paint horse was presented with gradual changes in behavior, characterized as stallion-like including aggressiveness towards people and other horse. The abnormal right ovary was detected via transrectal ultrasonography and rectal palpation. A complete blood count and biochemical panel values were within reference ranges. The hormone analysis revealed increased testosterone 46.00 pg/mL and inhibin 0.856 ng/mL, and progesterone concentration consistent with absence of luteal tissue 1.2 ng/mL more than normal values. The purpose of the study reported was to describe a ovariectomy of enlarged ovary by using the diagonal paramedian approach. This method is useful to minimize surgical exposure and hemorrhage. This ovary was confirmed fibroma by histological examination post operation. Behavior problems and the hormone values were alleviated after surgery, and clinical signs of complication were not showed.

This study was conducted to obtain the basic research about Siberian roe deer (Capreolus pygargus), and to establish a conservation area into Seoraksan(Mt.) National Park, South Korea. We recorded Siberian roe deer field signs (bedding sites, feeding areas, feces and tracks etc), and habitat variables such as nearest distance to the watercourse, trails, slope, aspect, forest type and land cover etc. from Jan. 2006 to Dec. 2007 in Seoraksan(Mt.) National Park. According to the research of habitat characteristics of Siberian roe deer inhabited in Seoraksan(Mt.) National Park preferred mixed forest consisted of aged forest and middle-aged forest on the gentle slope which was close to hydrosphere in the middle elevation area of altitude of 400~600m above sea level in Seoraksan(Mt.) National Park. The results indicated that Siberian roe deer appeared to prefer south slope or north slope during the snow season and west or east slope during the non-snow season. The area of most suitable habitat for Siberian roe deer in Seoraksan(Mt.) National Park was $128.5km^2$ (32% of the total area) followed by $244.3km^2$ buffer area (62.2% of the total area), and $22.9km^2$ unsuitable habitat area (5.8% of the total area), which means environmentally unsuitable habitat for Siberian roe deer was rare in Seoraksan(Mt.) National Park. Thus, the area classified as major area in Seoraksan(Mt.) National Park appeared to be most important for the protection of Siberian roe deer.

This study was carried out to investigate soil and environment characteristics of Schizandra Chinensis Baillon habitat as a part of establishment of conservation plan for important medicinal crop resources in Jangsu-gun, Jeollabuk-do. These habitats are mostly located on the slopes of mountains facing northwest at an altitude of 500 m to 700 m with angles of inclination ranging from 17.6 to 36.4%. Average yearly precipitation and temperature of Schizandra Chinensis Baillon habitat were 1,493.4 mm and $16.9^{\circ}C$, respectively. The number of plant species growing in Schizandra Chinensis Baillon habitat was found 55 species. Salix gracilistyla, Lespedeza bicolor, and Artemisia princeps var. were shown higher density and coverage. Chemical quality of Schizandra Chinensis Baillon habitats soils was relatively higher than artificial cultivation soil.

This study was conducted to compare the local climate conditions and growth periods for the apple (Malus domestica 'Borkh') orchards at different altitudes (330, 500, and 670 m) in Jangsu-Gun, Korea. Observation data for the growth period show that the monthly mean air temperatures at the 'Hongro' apple orchard sites decrease with height at the rate of 1.0 to $3.0^{\circ}C$/100 m. The monthly minimum temperatures in April (blooming period for 'Hongro' apple) were 4.3, 2.9, and $0.4^{\circ}C$ at 330, 500, and 670 m, respectively. The monthly mean temperatures in September (i.e., the coloration and maturation period) were 20.6, 18.7, and $14.5^{\circ}C$, respectively. The annual precipitation range varied from 1,234 to 1,439 mm, which tended to increase with height. The heavy rainfall occurred in summer (June to August) and amounted to 827-933 mm. No significant differences in the duration of sunshine were observed amongst the orchards at three different altitudes. The earliest bud break was observed at the 330 m altitude (18 March 2009), which was 4 and 11 days earlier in comparison to those at 500 and 670 m, respectively. The time of full bloom at 330 m was 12 days ahead of that at 670 m. The optimal maturation of fruit (based on skin redness > 80%) was observed between 7 and 10 September at 330 m, 15 and 18 September at 500 m, and 21 and 23 September at 670 m.
