Schwann cells(SCs), an important component of the peripheral nervous system, intract with nerous to mutually support growth and replication for the peripheral nerve regentation. Recently, ading SCs to the lumen of guidance channel is widely tried to improve regeneration or to make regeneration possible over otherwise irreparable gaps. however, it is not easy to isolate and multiplicate SCs as much as enough to help the axonal regeneration. For the allogeneic SCs source for tubular nerve guidance, we developed a little bit improved technique of harvesting and multiplicating SCs. by culturing dispersed dorsal root ganglia in specially designed medium with growth factors and serial processing, we repeatedlly generate relatively homogenous SC cultures. Our technique was compared with other methods of literature using immunostaining methods such as GFAP, S100, BDNF and the total SC count assessment at different time interval after primary culture.

The subfamily Lycorininae Cushman & Rohwer, 1920 is a small group with a single genus, Lycorina. This subfamily can be easily distinguished from other ichneumonids subfamilies by the following characters: impreesed triangular pattern on the metasomal tergites, tergite 2-4 with convex central triangular area; hypopygium of female large and triangular in lateral view, centrally membranous and with small median apical notch. Genus Lycorina is a cosmopolitan genus with 30 described species (Yu et al., 2012). Also, from this genus have been reported five species in Eastern Palaearctic region, six species from China, two species from Japan and one species for the first time from Korea. The focal host range appears to be weakly concealed larva of micro-lepidopteran species. Some species have been reared from Crambidae in leaf-rolls or webs (Doerksen & Neunzig, 1974; Finlayson, 1976) and Tortricidae (Chao, 1980; Shaw, 2004). In this study we report one newly recorded to Korea species, Lycorina triangulifera Holmgren, 1859 and provide the diagnosis and photographs.

The genus Pristomerus Curtis, 1836 is one of among 36 genera belonging to the subfamily Cremastinae. This genus is a large genus with 100 worldwide species distributed (Yu et al., 2012). Also, from this genus have been reported 15 species in Eastern Palaearctic, eight species from China, seven species from Japan and three species from Korea. Subfamily Cremastinae is known as koinobiont endoparasitoids of solitary larval-pupa mostly Lepidoptera and Coleoptera (Fitton & Gauld 1980). Spectrum of host species of Pristomerus include various small Lepidoptera living in tunnels, leaf rolls, buds and other hidden areas (Rousse et al., 2011). Genus Pristomerus can be easily distinguished from other genera by the following characters: hind femur with ventral tooth; deep gastrocoelus on tergite II. Three species from this genus, Pristomerus chinensis Ashmead, 1906, P. erythrothoracis Uchida, 1933, and P. vulnerator (Panzer, 1799), have been reported from Korea previously. In this study we report three newly recorded species, Pristomerus rufiabdomenalis Uchida, 1928, P. parilis Kusigemati, 1984, P. kendarensis Kusigemati, 1984, and described three new species. Here we provide the descriptions and photographs of six species of genus Pristomerus, and species key.

<P>This study investigated the preventive therapeutic effects of Hataedock (HTD) treatment on inflammatory regulation and skin protection in AD-induced NC/Nga mice under high-fat diet conditions. Before inducing AD, the extract of<I> Coptidis Rhizoma </I>and<I> Glycyrrhiza uralensis </I>was administered orally to the 3-week-old mice. After that, AD-like skin lesions were induced by applying DNFB. All groups except the control group were fed a high-fat diet freely. We identified the effects of HTD on morphological changes, cytokine release and the induction of apoptosis through histochemistry, immunohistochemistry, and TUNEL assay. HTD downregulated the levels of IL-4 and PKC but increased the levels of LXR. HTD also suppressed the mast cell degranulation and release of MMP-9, Substance P. The levels of TNF-<I>α</I>, p-I<I>κ</I>B, iNOS, and COX-2 were also decreased. The upregulation of inflammatory cell's apoptosis is confirmed by our results as increase of apoptotic body and cleaved caspase-3 and decrease of Bcl-2. HTD also reduced edema, angiogenesis, and skin lesion inflammation. Our results indicate HTD suppresses various inflammatory response on AD-induced mice with obesity through the regulation of Th2 differentiation and the protection of lipid barrier. Therefore, HTD could be used as an alternative and preventive therapeutic approach in the management of AD.</P>

Kaloula borealis is the species of Amphibia which belongs to Kaloula genus and it is the only species inhabiting in Korea. The population size and habitat of Kaloula borealis have been significantly decreased on a national scale due to the diversified developments and the uses of agricultural pesticides. Accordingly, the Ministry of Environment has designated and managed them as the class II of endangered species, in accordance with ?Endangered Species Protection and Management Act?; however, a particular study focused on the ecological restoration of Kaloula borealis is desperately needed to prevent their extinction. This study was conducted to propose the HSI (Habit Suitability Index) of Kaloula borealis based on literature survey on ecology and habitats of Kaloula borealis, as well as their HSI. Factors to be investigated in HSI include: space, feed, cover, water(breeding) and threatening factors and the variables of each factor were also proposed. The distance from wetland, grassland, farm, stream and rice paddy, as well as the altitude of spawning pond were proposed as the variables of space, whereas the bed structure of forest and low-rise grassland were proposed as the variables of feeding. The variables of water (breeding) include the area of permanent and temporary wetlands, coverage of emerged pants (ratio of open water), water depth, water temperature, water quality, pH level, etc., whereas the presence of predator, distance from street and pollutants were proposed as the variables of threatening factor. The sub-standards by HSI factor of Kaloula borealis have been drawn from in-depth consultation with experts and based on this, the final HSI of Kaloula borealis was developed.

This study was carried out to analyze the home ranges of three medium-sized mammals(Nyctereutes procyonoides, Prionailurus bengalensis, and Meles leucurus) inhabiting the Sobaeksan National Park, Korea. Three individuals of each species were captured using live traps(Tomahawk live trap 210A) and radio tracking was conducted from June 2012 to May 2014 using VHF and CDMA methods. We determined that the home range of N. procyonoides was 6.53±6.66 km2(MCP 100), 3.39±4.73 km2(FK 95), and 0.48±0.62 km2(FK 50), that of P. bengalensis was 7.13±5.61 km2(MCP 100), 7.77±3.91 km2(FK 95), and 1.88±0.96 km2(FK 50), and that of M. leucurus was 1.77±1.82 km2(MCP 100), 3.17±4.52 km2(FK 95), and 0.63±0.87 km2(FK 50). The home ranges of both N. procyonoides and P. bengalensis were greater than that of M. leucurus, and moreover, both were larger than 6 km2(P. bengalensis>N. procyonoides). The results also showed that for each species, 1.2~4.4% of the home range overlapped with that of the other two species and that this overlap occurred in the vicinity of a water system.

Riparian areas are significant functional grounds for inhabiting ecological system on the river such as the self-regulation of the water quality and the foundation of important corridors. For such functional device to operate, consecutive land purchase scheme that prioritizes targeted areas with high pollutant load rate imposes sustainable development of the ecological riparian belt. The purpose of this study is focused on measuring the methodology for selecting land purchse order before establishing riparian belt in accordance with pollution loading estimation and the basin approach. The Yeongsan and Seomjin river which includes targeted areas of the land purchase have been classified into the large-medium-small(standard basin) influence areas based on their catchment rage, which than sub-divided the research area of Juam lake by 38 small basins and 223 units. Small basins with the high pollution load rates have been assessed as the first prioritized targets. For the second priority, the condition of the point pollutant sources, original area of the targets, original restored area were concerned. The final decision of the land purchase order targeted only those within 50 meter range from the basin. To validate the accumulated data, the on-site investigation went along the targeted zones, which the result shows that all prioritized areas included both point and non-point pollutant sources, and had not a small originally restored areas.

This research was completed to provide fundamental data regarding the guidelines to installing and managing utility facilities & structures in wetland protected area to advance the functions and sustainable use of ecology services by preserving the ecology within wetland protected area. There were 5 on-site researching areas that were used as the main subject with these areas chosen and considered from 21 inland wetlands that have been designated and are being managed from the Ministry of Environment and by their designated dates as a wetland protected area. The utility facilities in these wetland areas were categorized by their types and a detailed on-site investigation was proceeded with investigation items chosen whereas these facilities are working by their roles from their location, size, used materials, types, information contents and etc., The results showed that regarding informational structures, several locations of information boards were distanced from the main exploring routes which did not consider the visitor``s eye level which had their readability dropped and by sunlight, time lapse and water penetration, many information boards were damaged or corrupted so that it was hard to confirm the information noticed or understanding an image. Insufficient observation and educational structures were installed that considered the ecological characteristics of wild animals and their living conditions. Regarding convenience facilities, there were parking lots that were installed on the fore-land and to decrease non-point solution sources, some parking lots needed to be located in protected lowlands while some facilities`` shape and colors did not harmonize with their natural surroundings, creating a sense of awareness, which will need some more consideration. As for safety facilities, they were very insufficient compared to other facilities. This means that additional safety structures areneeded so that related personnel can be aware of where a visitor is located when an accident occurs. Protectional facilities strongly needed new structures and a management system to cut off entrances and do surveillance so that visitors do not go into areas outside of the managed areas and bring damages to restricted locations. Research labs needed to expand the use of automatic weather systems and water gauge equipments to build fundamental data regarding floodgates that are intimated to the forming of wetlands. Sensor cameras and other types of monitoring systems are needed to monitor the majority types of animals living in the wetlands as well.
