During the COVID-19 pandemic, social distancing affected daily life and leisure activities, including forest recreational activities. This study identified changes in people's participation in forest recreational activities and factors affecting their participation. It collected data from 1,000 samples through an online survey and analyzed it using a binary logit model with interaction terms. It was observed that there were decreases in the participation in visits to urban parks and green areas, outdoor activities in forests and mountains, and trips to mountain villages after the COVID-19 outbreak. People in their 40s, 50s, and 60s were more likely to decrease their participation in all kinds of forest recreational activities than those in their 20s. Moreover, higher household income earners were more likely to decrease their involvement in outdoor activities in forests and mountains. With respect to the place of residence, the residents in the Seoul metropolitan area were less likely to decrease their participation in trips to mountain villages than those outside this area. Thus, this study suggests that online forest recreation information services and forest management are needed to meet the demands of forest recreation for young generations and diversify the function of forests and rural areas as a safe leisurely space.

This study was conducted to analyze the openness of erosion control dams situated near mountain stream. The ecological functions of erosion control dams analyzed by such openness for adequately protect and manage the diversity of species and to prevent disasters. The obtained results were as follows. When structurally modifying or changing non-permeable, gravity type dams with a passing rate of less than 1% into open-type dams, the passing rate increased by about 77 times more from 0.72% to 55.8%. Except for closed, gravity type erosion control dams that are constructed with a special purpose such as creating sand deposits and reservoirs, there is a need to construct and improve the dams into permeable type dams that can relatively satisfactorily perform various functions such as carrying soil and sand to the downstream region and create a ecological corridor upstream and downstream for fish and amphibians. The openness based on the blocking height of the erosion control dam varies depending upon the height of the base part and the depth of the substructural part. It must be designed based on the on-site conditions and the purpose of the construction. The functional types of erosion control dams based on the open form of the cross-section as follows: the fish traffic type, flood control type, reservoir type for forest fire control), non-permeability type for soil and rock blocking, net type for blocking the rock flow and the particle screen type.

In Korea, torrential rain frequency and intensity have surged over the past five years (2019-2023), breaking rainfall records. Due to insufficient observation facilities for rainfall and runoff data in small mountainous catchments, preparing for unexpected floods is challenging. This study examines the Bidogyo catchment in Goesan-gun, Chungcheongbuk-do, comparing design flood discharge calculated with optimized parameters versus standard guidelines. Using HEC-HMS and Q-GIS for model construction, five rainfall events were analyzed with data from the National Water Resources Management Information System. The time of concentration (Tc) and storage constant (K) were calculated using the Seokyeongdae formula and model optimization. Results showed that optimized parameters produced higher objective function values for flood events. The design flood discharge varied by -10.7% to 17.3% from the standard guidelines when using optimized parameters. Moreover, optimized parameters yielded flood discharges closer to observed values, highlighting limitations of the Seokyeongdae formula for all catchments. Further research aims to develop suitable parameter estimation methods for small mountainous catchments in Korea.

In this study, space allocation with an assessment system for improving the function of the ecological use and function of each space was undertaken to suggest appropriate goals and directions. Ogeum Park, used as the study site, is a stronghold green zone located in the fan-shaped area of the Songpa-gu green zone on a 22ha area site. The assessment system for this study consisted of a total of 3 steps: Step 1 includes the division of the spatial block, Step 2 assesses the proper functioning of each spatial block, while Step 3 includes space allocation and presents improvements for function by space. This study performed a basin analysis with the consideration that Ogeum Park is a forest area and divided the site into a total of 8 areas according to how the sections of land are used. The function of wildlife habitat included an analysis of plant ecology(vegetation type, vegetation layer, potential vegetation), animal ecology(wild birds), and waterways. The function of leisure and use included an analysis of gradients, noise, paths, status of use, and status of facilities. The evaluation of the function of habitat sorted items into native vegetation, vegetation diversification, vegetation potential, animal diversification and potential of animal habitats. The results of grading the evaluation scores by space in the function of habitat showed that the Areas IV and VII, which were 90% of the maximum point, were Grade A, Areas II and V were Grade B at 70% and Area I and VI were Grade C at 50%. Areas III and VIII, which were not found to be beyond the standard of 50%, were excluded. The evaluation of the functions of leisure and use classified items into use potential, use preference, use concentration, use diversification and use convenience. The results of the graded evaluation scores by space in use function, showed areas V and VI as Grade A, or 90% of the maximum score. Grade B, 70% of the maximum score, was given to Areas I and VII. Grade C, 50% of the maximum score, included Areas II, IV and VIII. Area III, graded lower the standard of 50%, was excluded. The study evaluated areas according to a common standard, classified spaces by proper functions into ecological spaces, environmentally-friendly use spaces and use spaces according to the standard of spatial distribution on the basis of the above results through a synthesis of grades of habitat function, leisure function and use. This offers ideas for the improvement of wildlife habitat and environment-friendly use functions by space.

In order to know the morphology and the function of the fat-storing cells (FSC) of the squirrels which were captured at the Pal-Gong mountain near Taegu in December, 1980 (Group A) and May, 1981 (Group B), respectively, the light and electron microscopic observations were conducted on the liver of the squirrels. The results obtained are as follows: 1. Light microscopically, the size of the lipid droplets in the FSC of group A was uniformly larger than those in the cells of group B, and number of the droplets in the FSC of group A was less than those in the cells of group B, The distribution of the FSC of group A was mainly perilobular area while those of group B was centrolobular and midzonal areas. In this point of view, the FSC of the squirrels was similar to those cells of the hamsters. 2. Electron microscopically, general morphology of the sqirrel's FSC was accorded with those of the other mammals. However, the rouph surfaced endoplasmic reticulum in the FSC of group B was more dilated than those in the cells of group A, and more lipid droplets and pinocytopic vesicles were observed in the FSC of group B than those in the cells of group A. 3. From the above evidences, it could be suggested that the metabolic rates in the FSC of the squirrels collected in the spring were higher than those in the cells of the animals collected in the winter.

The purpose of this study is to look for a development plan for strategic brand logo by a means of scrutinizing general characteristics and trend in the visual properties of outdoor logo brands. In this study, data research and analysis were conducted over the 68 outdoor brands in circulation in the domestic market based on the information on the website of each brand in order to examine the visual characteristics of an outdoor brand logo. For this, it was performed to examine the desired brand concept of each brand and to analyze the visual characteristics of typeface, color, and type of logo. The results of this research are the followings: First, it was found that the most popular typeface in outdoor brand logos is a capitalized Gothic type. It seems that the logo type is designed to symbolize power, toughness, and masculinity and to express the concept of sportswear brand. Second, when it comes to color, black color tone appeared most frequently, and also reddish colors among chromatic colors were prevailing over others like green, blue, or yellow. It is believed that reddish colors were used to express passion, power, youthfulness, and energy; black color tone for tough, masculine power. Third, the logo symbol of outdoor brands mostly contains mountain, the heads of powerful animals, spherical shape/abstract image that embodies outdoor sports activities. It was analyzed that these resulting symbols were chosen to convey the images of nature, conquest, challenge, future, and passion that are the brand concept of most outdoor brands. Today, in our country, the logo of an outdoor brand is the important factor that symbolizes the brand concept, function, or characteristics. Therefore, the necessity of constant follow-up researches is required to devise the way of designing the brand logo that can build brand power and enhance brand image.

This study was conducted to understand the distribution characteristics of old tree (protected tree) and propose the effective management plan for old tree to make hold a sustained function as natural and cultural resources in rural area. We surveyed 96 old trees at 69 farm villages in Yaesan-gun, South Chungcheong Province. The species of tree was investigated with Zelkova serrata, Ginkgo biloba, Quercus acutissima, Pinus densiflora, Celtis sinensis, and Juniperus cbinensis order. Most of them located at the inside (43.6%) and the entrance (35.1%) of a village, and at mountain slope (31.9%) and alluvial plain (25.3%) in terms of distribution topography. The existing place of pollution source was investigated with 61%, and the pollution sources were blocks, construction materials, cement packings, farm machines and living garbage. The place where the rates of bare ground were more than 50% for the root region of a protection tree was 63%. The tree surgical operation was investigated in 37.5% of protection trees, and 12.5% of protection trees were investigated with a tree surgical operation being immediately. The average score for health condition of old tree at study sites was 18.6 points. A monitoring class was divided by public monitor 59.3%, main monitor 38.5%, and dead tree 2.2% on the basis of that information. Hereafter, we will conduct to promote the management guideline and develope culture contents through additional investigation.

Objectives: This study introduces the history and types of Korean pharmacopuncture and reports trends of research on Korean pharmacopuncture. Methods: Pharmacopuncture studies were searched from the first year of each search engine to 2014 by using seven domestic and foreign search databases. Selected studies were divided into the history of pharmacopuncture, kinds and features of pharmacopuncture, research types, and experimental and clinic studies and were then classified by year of publication, type of pharmacopuncture, disease, and topic. Results: Pharmacopuncture can be classified into four large groups: meridian field pharmacopuncture (MFP), eight-principles pharmacopuncture (EPP), animal-based pharmacopuncture (ABP) and mountain-ginseng pharmacopuncture, which is a single-compound pharmacopuncture (SCP). The largest numbers of studies were reported from 1997 to 2006, after which the numbers decreased until 2014. Of experimental studies, 51.9%, 18.7%. 14.3%, 9% and 3.4% were on SCP, ABP, MFP, formula pharmacopuncture (FP), and EPP, respectively. Of clinical studies, 54.7%, 15.3%. 14.9% 10.0% and 1.5% were on ABP, MFP, EPP, SCP, and FP (1.5%), respectively. Among clinical studies, case reports and case series accounted for 76.5%, followed by randomized controlled trials (RCTs, 16.4%) and non-RCT (13.9%). Musculoskeletal diseases, toxicity and safety tests, anti-cancer effects, and nervous system diseases were mainly treated in experimental studies while musculoskeletal diseases, nervous system diseases, toxicity and safety tests, and autonomic nerve function tests were addressed in clinical studies. Bee venom (BV) was the most frequently-used pharmacopuncture in mechanism studies. Pharmacopuncture was mainly used to treat musculoskeletal diseases. Conclusion: Pharmacopuncture and studies of it have made great progress in Korea. Studies on BV pharmacopuncture and musculoskeletal diseases accounted for most of the studies reported during the review period. Research on the types of pharmacopuncture and diseases has to be expanded. Especially, studies on the use of MFP and EPP for treating patients with various diseases are needed.

The Second Namsan Tunnel required renovation. The landscape design was conducted as part of the comprehensive programs for renovation. The landscape design covered site analysis, design development, a working drawing and a maintenance plan. In May of 2001, the Second Namsan Tunnel was renovated and reopened to traffic. The tunnel was recreated as a new type of tunnel with function and beauty. The entrance and retaining wall of the tunnel has public character. Users are greatly affected by the entrance and retaining walls along roads. The landscape architect had to find new materials and methods to improve the environment and to combine artwork with the entrance and walls of the tunnel. The surface of the tunnel entrance and retaining walls are artistically treated with ceramic tiles and paint. Various regional characteristics and cultural meaning are symbolically expressed. Or the tunnel entrance from the Joong-gu side, entitled "Glory of the Future", the hibiscus symbolizes the bright and glorious future of Korea. On the retaining walls, entitled "Hope", the promising Joong-gu is symbolized through image of Korean magpies, mountains, rocks, roses, winds and nature. As for the tunnel entrance from the Yongsan-gu side, entitled "Vivid Spirit", pine trees symbolize the Koreans′strong will and an enterprising spirit. On the retaining walls, entitled "Lively Motions", Yongsan-gu is symbolized through image of pigeons, mountains, rocks, roses, winds and clear skys. The entrance and retaining wall of the Second Namsan Tunnel, whose surfaces are treated with tiles and paint with artistic value, would create an atmosphere using large-scale wall paintings. In this artwork, users would perceive a unique sense of place through the symbolic images of the vertical planes of the tunnel.

Rural areas dominates the country landscapes in size with less population and rich traditional heritages as well as natural landscapes. Rural community groves (RCG) and Dangsan groves have been established by community residents during a few hundred years, and most of them have been disturbed. Only a few RCGs and Dangsan groves remain for an extensive period with efforts from community residents. These remnant RCGs and Dangsan groves are highly evaluated representing Korean rural cultural landscapes. Sound understanding on the structure of the rural landscapes and their role on the rural community environment is required to provide an appropriate policy for managing rural landscapes. This study aims to understand the characteristics of RCGs and Dangsan groves in the cultural landscapes, to investigate policies and issues of the advanced countries on RCGs and Dangsan groves, and to overview domestic policies for rural landscapes. The study results showed that there is a close relationship between RCGs and main issues discussed in EU countries. Ministry of Agriculture & Forestry of Korea, Ministry of Environment and Rural Development Administration have to focus on the potential of RCGs and Dangsan groves for multi-functions of agricultural and rural areas, natural streams, rural amenity, direct subsidy for landscape preservation and rural tourism. Based on the findings, this study suggests that RCGs and Dangsan groves will provide benefits to develop rural-mountain-sea villages and to enhance country's landscapes as well as local landscapes.
