Rhododendron mucronulatum, native to Korea, Mongolia, Russia and parts of northern China, is known not only for its medicinal properties but also as a tourist attraction. One of the most famous tourist destinations with R. mucronulatum is in Biseul Mountain County Park, Daegu, Korea. To investigate the relationship between R. mucronulatum and microbiome communities in the surrounding soil, three sites within the park were chosen for sampling in February and August. The soil samples were then passed through a pyrosequencing process for analysis of the bacterial communities, and a total of 404,899 sequencing reads were obtained. Between 2,349 and 4,736 operational taxonomic units (OTUs) were observed across the three sampling zones and two seasons; samples from the park entrance showed a higher number of OTUs than the other two sites, and samples from August had more OTUs than those from February. The sample from the second observation site displayed the fewest OTUs, particularly in February. According to Chao1 and Shannon indices, samples from the park entrance in August demonstrated the highest degree of species richness and diversity. Studying the bacterial communities across the six samples identified the common population as comprising 287 genera, 45 of which are only present in Biseul Mountain County Park and are expected to participate in the colonization of R. mucronulatum.

Researching the soil fungal community is important to understand the interaction between fungi and living plants. However, too few studies have examined the soil fungal community and their interactions with plants. Rhododendron mucronulatum, commonly known as Korean rosebay, is an important forest resource that has aesthetic, ecological, and potential pharmacological values. We used a pyrosequencing method to analyze the characteristics of fungal communities from R. mucronulatum soil samples from Biseul mountain county park, which is one of the famous places for large R. mucronulatum colonies in South Korea. We collected soil core samples in February and August at three sites in the Biseul Mountain County Park, taking into consideration the regional and seasonal conditions. We obtained 454,157 validated reads after pyrosequencing all six samples. The fungal communities from the first observation spot in August had the richest species diversity among the samples. Basidiomycota, Ascomycota, and Mortierellomycota were major phyla in the samples. Agaricales_f, Mortierellaceae, and Clavariaceae were major families in the samples. The genus Mortierella was the most dominant in all six samples. Overall, 19 genera could be associated with R. mucronulatum. Sample 1 had 109 genera in sample 1, sample 2 had 111 genera, and sample 3 had 112 genera that were uniquely identified. The samples collected in August had 28 identified genera, that existed only in summer samples, indicating a weather effect. This study can be used as basic research to understand the relationship between soil fungi and plants.

There are various granite landforms including block stream(natural monument No. 435) within Mt. Biseul, in Daegu city. The Daegyunsa(temple) and community of rhododendron around the summit of the mountain provide visitors many objects o( interest in cultural & ecological heritage. This paper aimed to develope nature trails of various type according to visitor's characteristics. 1) Various granite landforms develope along with the main path up the mountain(block stream-gnamma-exfoliation-poligonal cracking-talus-core stone-sheeting joint-tor-free face-high flat summit). 2) The explanatory note on terminology, origin, characteristics of geomorphic resources are developed in this paper for the first time. 3) In Consideration of the path line of flow of visitor, the best field study sites and the most effective nature trails are designed for visitor. 4) Three nature tails are designed for visitor according to the type and the length of visitor's stay.

The fish fauna and community structure at 20 stations in streams of the Mt. Biseul were investigated from June 2003 to May 2004. During the study period, 29 species, 25 genera belonging to 9 families were collected. Cyprinid fish occupied 48.3% (14 species) and cobitid fish had 13.8% (4 species). Six species (22.2%) were korean endemic and two species of Micropterus salmoides and Lepomis macrochirus were exotic. It was found that the population density of carnivorous fish (Opsariichthys uncirostris amurensis) increased in the lower-reach of small streams in the Mt. Biseul area since it had been introduced from the other native rivers in the middle 1990s. As the result of analyzing fish community in the surveyed area, the species diversity ranged from 0.553 to 1.023. The findings showed that the Geumpo, Chacheon and Hyeonpung streams had higher species diversity indicies of 0.936 ${\sim}$ 1.023 than the Sincheon and Gisegok streams with 0.553 ${\sim}$ 0.727.

This paper has obtained the following results by investigating the physical geographical names appeared on the school songs of the primary secondary school in Daegu metropolitan city. 1) The physical geographical names appeared many on the school songs in the old-established schools are the traditional physical geographical names such as The Mt. Palgong, The Geumho river, The Nakdong river, The Mt. Biseul and the physical geographical names related to the identity of Daegu such as Dalgubeol, The Mt. Taebaek, Seorabeol and so forth. 2) The physical geographical names appeared many on the school songs in the primary schools are The Mt. Palgong, The Geumho river, The Nakdong river, and The Mt. Biseul in order, while those appeared many on the school songs in the secondary schools are The Mt. Palgong, The Geumho river, The Nakdong river, and The Mt. Biseul in order. 3) Since The Mt. Taebaek and Seorabeol relatively often appear in the physical geographical names, we can find the relationship between Daegu and Silla Dynasty, and that between The Mt. Palgong and The Mt. Taebaek from the viewpoint of feng shui. 4) In case of the school songs in the schools distributed around the area of Suseong-Gu and DalSeo-Gu which are newly developed, the physical geographical names within the two areas in addition to the traditional physical geographical names(including the physical geographical names related to the identity of Daegu) appeared many on the school songs. 5) The Mt. Palgong, which is the representative physical geographical name of Daegu, almost did not appear on the school songs of the schools within the Dalseong-Gun. In other words, the residents in the Dalseong-Gun have recognized the mountain based on The Mt. Biseul rather than The Mt. Palgong. 6) It is special that The Sincheon amounting to the central stream in Daegu almost did not appear on the school songs. 7) It is concluded that the physical geographical names found in this paper can be not only set as main ecological space in Daegu area but also considered in top priority as ecological space in the various plans of development.

There is always a risk of water disasters due to sudden storms in mountainous regions in Korea, which is more than 70% of the country's land. In this study, a radar-based risk prediction technique for sudden downpour is applied in the mountainous region and is evaluated for its applicability using Mt. Biseul rain radar. Eight local heavy rain events in mountain regions are selected and the information was calculated such as early detection of cumulonimbus convective cells, automatic detection of convective cells, and risk index of detected convective cells using the three-dimensional radar reflectivity, rainfall intensity, and doppler wind speed. As a result, it was possible to confirm the initial detection timing and location of convective cells that may develop as a localized heavy rain, and the magnitude and location of the risk determined according to whether or not vortices were generated. In particular, it was confirmed that the ground rain gauge network has limitations in detecting heavy rains that develop locally in a narrow area. Besides, it is possible to secure a time of at least 10 minutes to a maximum of 65 minutes until the maximum rainfall intensity occurs at the time of obtaining the risk information. Therefore, it would be useful as information to prevent flash flooding disaster and marooned accidents caused by heavy rain in the mountainous area using this technique.
