Tigers are the large cats with prominent, black or brawn, stripes. They are common in jungles of India and Java, but range as far as the snowy, forested mountains of Siberia. Legal and illegal killing(over-hunting, poaching for skin, and also its bones, f

On the basis of vegetation data in the 9.12 ha (380 m ${\times}$ 240 m) permanent sample plot of the spruce-fir valley forest in Liangshui National Reserve of Xiaoxing'an Mountains, the study was conducted to evaluate spatial distribution pattern and spatial association by using point pattern analysis for living and dead trees of Larix gmelini by DBH size class. The number of L. gmelini were counted as 59 living stems/ha (6.42 $m^2$/ha of basal area) and 34 dead stems/ha (2.86 $m^2$/ha of basal area). The distributional curve of diameter class exhibited bimodal shape. The analysis of spatial distribution patterns of all living larch stems noted the clumped distribution on the whole. The size of larch aggregates of dead stems was decreased as diameter class was increased. The distribution of dead stems became gradually randomized with decreased clumped size as the scale increased. Living stems and dead stems of the larch had positive spatial association at most of scales, illustrating that the occurrence of mortality of the larch tree was closely related to the distribution pattern of living larch trees.

Characteristics of digital broadcasting are multi-channel, high-definition and multi-function. especially, multi-function is enable us to do a variety of services except for an image and a voice. This paper, therefore, is analyzed propagation environment in Busan into ETRI model application about 지상파 DMB service. It takes to be simulated in Busan area around the mountains area and high building. So it measures the electric field strength in standards. Distribution pattern are similar with mutually in the 이론 and real measurement. Even areas are almost the same, but urban areas and mountains are different with mutually. Therefore, we conclude that ETRI propagation model and theoretical modeling in a free space in Busan area is not suitable.

Four parks were selected to study the current situation after large scale suburban housing development in the 1990s. Since housing development road network have expanded with other facilities. First of all, green space area available per housing unit is 7.11- 22.0 sq. m. These parks neither extend as green corridor with surrounding hillside mountains (the river or lakes) nor act as the wind path from the mountains. Some housing units have reconstructed and the others will be redeveloped in near future which would more challenges for the residents in terms of quality of their life.

The contents of Pb and CD measured with the barks of Pinus densiflora in Seoul area, Yangjaedong area near the Kyungbu-highway, Mt. Keryong and Mt. Seolak area, from Sep. to Ock. in 1988. Pb contents in Seoul area were 17.8 ppm at Changkyungkung, 17.1 ppm at Chongamdong, 13.2 ppm at Mt. Kwanak, 7.6 ppm at Mt. Dobong and 3.7 ppm at Mt. Surak. Except Mt. Kwanak, the difference between areas of central and mountains in Seoul were high significant. Mt Seolak area also showed variations in Pb contents from 16.8 ppm to 32.1 ppm according to studied sites. Cd contents in Seoul area were 0.47 ppm at Changkyungkung, 0.65 ppm at Chongamdong, 0.61 ppm at Mt. Kwanak, 0.52 ppm at Mt. Dobong, 0.47 ppm at Mt. Surak. Therefore, Cd contents in Seoul area exhibited more variations between sampling plots than between the areas of central and mountains in Seoul. Mt Seolak area also showed variations from 0.20 ppm to 0.34 ppm in Cd contents, and it was the lowest in all the studied area.

We report the first identification of a spawning ground of the blackfin flounder Glyptocephlaus stelleri near the Wangdol-cho sea mountains, located in the southern East Sea. Eggs and larval fish of G. stelleri were collected during April and June, 2014, when an abundance of eggs was found in the southern area of Wangdol-cho. Our findings suggest that G. stelleri prefers to spawn in the vicinity of the off-shore sea mountains, where the temperature is between 10 and $12^{\circ}C$ and the water depth is 100 m, rather than inshore.

We investigated the bryophyte flora of Taebaeksan Mountain National Park in Korea by conducting a total of ten field surveys from April of 2017 to October of 2019 at various mountainous sites in the park. During the surveys, we recorded 274 taxa belonging to 68 families, 143 genera, 267 species, 3 subspecies, and 4 varieties. Among these, 92 species were reported as new to the flora of the Taebaeksan Mountains. A checklist based on a study of 990 specimens is provided as well. The most remarkable species were Sphagnum capillifolium (Ehrh.) Hedw, Sphagnum girgensohnii Russow, Buxbaumia punctata P.-C. Chen et X.-J. Li, Pleuroziopsis ruthenica (Weinm.) Kindb., Ptilium crista-castrensis (Hedw.) De Not., and Douinia plicata (Lindb.) Konstant. et Vilnet.

This study was attempted to review the information data for minimizing the destruction of environmental naturalness and the visual damage of landscape from road construction by establishing a model of environmental naturalness for national roads in the suburb areas to suggest an answer to a research question, ' hat does decide the environmental naturalness of roadscape?'. We found that 1) The road-side slope showed no statistical significance in the description of environmental naturalness of roadscape, but the fact that the road-side slope from road construction is the destruction of natural topography cannot be overlooked. 2) In terms of the direction of value variations for independent variables, signboard and telegraph post, soundproofing and protection wall, structure, and building acted toward negative (-) direction, while mountains, sky, road trees, fields, and surrounding green including the road-side slope acted toward positive(+) direction. 3) The variable with highest relative contribution to dependent variables among independent variables is building, which has importance as many as 148 times of road-side slope, while the variable road-side slope has the least importance. Building has the importance of 7.22 times, mountains 5.51 times, road trees 2.59 times, surrounding green 2.54 times, structure 2.41 times, signboard and telegraph post 2.37 times, soundproofing and protection wall 2.20 times, and sky 1.32 times of the fields as a standard criterion values 1.

This study was conducted to obtain the information of distribution, protection and management for mammal species in fragmented forest areas around the road from June 2002 to May 2003 in 9 study sites of Baekdugdaegan mountains, Korea. Field signs of twelve mammals, moles Molera robusta, Korean hares Lepus coreanus, Manchurian chipmunk Tamias sibiricus, red squirrels Sciurus vulgaris, Korean racoon dogs Nyctereutes procyonoides, Siberian weasels Mustela sibirica, badgers Meles meles, otters Lutra lutra, Bengal cats Felis bengalensis, wild boars Sus scrofa, water deer Hydropotes inermis and roe deer Capreolus pygargus were recorded in this study. There were no differences in total number of species between 50 m areas and 50-100 m areas from road in snow and non-snow season. Number of mammals' field signs were different in non-snow season between both areas. Red squirrels and Siberian weasels were more abundant in 50 m areas, and Korean hares and Manchurian chipmunks were in 50-100 m areas. Habitat using pattern of mammal species may be affected by the road. Reasonable road construction and maintenance would be needed for protection and management of wildlife and their habitats.
