This research was carried out to provide a good quality forest healing program as a basic source of development by researching the general characteristics of users of Geiji Mountain in North Jeolla Province, the recognition of forest healing and regional preference programs. As a result of the survey, Geigisan Mountain is used as a natural place for recreation and leisure of residents of Jeonju. The most important factors in the selection of forest healing programs for visitors were the activities, organization and chronology of the program, and the main purpose was to improve health. Week-by-week programs utilizing weekends were preferred for management of forest healing programs. It was revealed that sports programs prefer to enjoy natural scenery, forest experience programs, healing programs, forest therapy programs, meditation programs, and listening to forest music. The outcome of this study is expected to be used as a basic source for developing and researching a program for forest healing in the area of Mt. Meanwhile, the limit on the composition of suitable forest healing programs according to preference is required for continuous and continuous integrated study of the forest healing program for the future of the forest healing program.

The purpose of this study was to explore how designers use software-based design tools for ideation and collaboration (for two cases: with designers and with developers). We conducted logistic regression analysis and random forest analysis. Software-based design tools are more popular among product designers and affiliated with design organizations with 51 to 100 members. We identify the features that influence designers to use design tools for the ideation and collaboration, and how these usage patterns are interrelated. Interrelated usage pattern is a key consideration for location of the menu and convenience of use. The results imply that reinforcement of the design tool features per designer profile is required and that design management should be consistent with the field of design and the nature of the organization.

The purpose of this study is to estimate the design flood runoff for ungaged forest watershed to reduce the flood damage in national park. Daewonsa watershed in Jirisan National Park was selected as study watershed, of which characteristic factors were obtained from GIS data. Flood runoff was simulated using SCS unit hydrograph module in HEC-HMS model. SCS Curve Number (CN) was calculated from forest type area weighted average method. Huff's time distribution of second-quartile storm of the Sancheong weather station, which is nearest from study watershed, was used for design flood runoff estimation. Critical storm duration for the study watershed was 3 hrs. Based on the critical duration, the peak runoff for each sub-watershed were simulated. It is recommended to monitor the long-term flow data for major stream stations in National Park for a better reliable peak runoff simulation results.

The expression of natural backgrounds in a digital clip such as forest, water and sky break new ground and evolve. The process of arriving at a certain background style and designing belongs to the pre-production stage of animation produuction. Due to the advancement of CG technology, the production and consumption of animation has accelerated and so in an effort to reduce production time, the natural background has increasingly becomme normalised. For the distinction in contents, narrative and characters are emphasized in pre-production since it is believed that the background design will simply be a still image. However, there is a need to focus on background design as it is a tool that can effectively emphasize the narrative. This research is an analysis of the background design's role in forest background in productions such as "Alice's Adventures in Wonderland"(1951) and "Princess Mononoke"(1997). It details how appropriate each background forest was for the artist's intent using the 7 types of forest landscapes according to dendrology.

This study aimed to enhance seed productivity and secure genetic resources for Pinus densiflora for. multicaulis. We analyzed the characteristics of cone and seed generated by control pollination between Pinus densiflora (PD) and Pinus densiflora for. multicaulis (PDM). The highest number of cone scales (63.0) was obtained from the self-pollinated (sp) PDM clone B (PDM-sp-B), whereas the lowest number of cone scales (44.7) was obtained from two combinations designated as PDM-A×PD-075 and PDM-A×PD-0111. Both female parents of the hybrids were PDM-A. The highest seed production capacity (80.8) was obtained from the open-pollinated (op) PDM clone B (PDM-op-B). The seed potentials of PDM-B×PD-0111, PDM-op-A, and PDM-sp-B were 67.4, 66.5, and 63.1, respectively. The highest number of fertile scales (41.5) was obtained from PDM-op-B, and the lowest number of fertile scales (28.8) was obtained from PDM-A×PD-075. The total number of aborted ovules and 1st aborted ovules was not statistically significant in the mating design. The cross combination of PDM-B×PD-0111 had the highest number (34.8) of filled seeds and the lowest number of 2nd aborted ovules (5.2) and empty seeds (9). PDM-op-B had the highest number of developed seeds (47.6), although the number of empty seeds was the highest (41.2). Therefore, we conclude that the mating design of PDM-B×PD-0111 is useful for future breeding programs to improve seed yield of PDM. Our results showed that there was a strong correlation between the following two parameter pairs: number of scales and number of fertile scales, and the number of fertility scales and seeds potential (r=0.89 and r=0.84, respectively; both p<0.01).

Recently, as people have become more interested in health issues, their demand on forest trails for bush walking exercise has increased. The purpose of the study is to select barrier factors into forest trail for disabled using wheelchairs. As a result this, it has selected 31 barrier factors through the Delphi method. Of all the these factors, the information board of forest trails, showing the location of the trails, has indicated the highest score of importance at 4.50. Next, securing hiker' walking safety space has indicated an importance level of 4.44; both the slope of forest trails and the height of obstacles have indicated an importance level of 4.38; and the effective width of forest trails has indicated the highest score of importance level of 4.33. From these indicated levels of importance, the respondents of the Delphi method consider the safety of users of forest trail' as the most important factor while the physically disables are hiking. That is why these factors have resulted in acquiring relatively higher values.

This study was intended to investigate effects of building school forests on elementary school students, including changes in mental image of school, attitude toward nature and forest, and awareness of their relationship with school forest. The total number of 770 drawings and 1,124 writings were collected to be analyzed from three elementary schools. The results showed that there were significant differences between two student groups, respectively forest school group versus non-forest school group, in their mental image of school. For instance, more often observed in the drawings of forest school group students than their counterparts were natural and human elements, activities associated with nature, and natural or human elements located at central area. Also, more frequently found in the writings of forest school group students than their counterparts were letter-style sentences, stories about school forests, inherent values on nature and forest, and curiosity regarding the nature. These results seem to indicate that in order to materialize educational value of school forests, practical workshops for teachers need to be held as soon as possible and new activity models for students should be developed. In addition to that, long-term research on effectiveness of school forest have to be conducted to a number of schools.

The plot design influences the budgets and the precision of forest inventory results. The objective of this study is to determine the efficiency of estimating forest variables such as tree density, basal area, volume, and species richness based on various plot sizes using fixed-area plot sampling in the natural deciduous forest of Pyeong-Chang County, Gang-won Province, Korea. In this study, 108 reference plots were established with a fixed plot size and shape of 0.09 ha ($30m{\times}30m$). In order to determine the optimal plot size for the interest of variables, each sample plot was established using different shapes (square, circle, and rectangle) and was divided into different plot sizes from 100 to $900m^2$. The mean relative difference (MRD) for the sum of the basal area and volume, and tree density per hectare decreased as plot size increased. But the MRD for three variables were only below 13% at the plot size of $500m^2$. Species richness for each reference stand observed ranging from 2 to 15 species, demonstrated highly positive significant relationships with plot size. The minimum plot size for the estimation of tree density, the sum of the BA and volume was determined to be about $400m^2$, whereas the estimation of species richness required a minimum plot size of $500m^2$.
