Objectives: The occurrence characteristics of BTEXS and phytoncides were investigated by type of urban forest. Methods: Four types of urban green space (Hongneung Forest, Mt. Chunjang, residential park, and traffic island) and Gwangneung Forest were selected. Monitoring of phytoncides and BTEXS was conducted considering the activity times of urban residents (five times per day) using a Tenax TA tube and suction pump in June 2017 (one day). Results: Phytoncide concentrations were ranked as Gwangneung Forest>Hongneung Forest>Mt. Cheonjang>traffic island>residential park. Relatively high concentrations of phytoncides were also identified in the urban forest. There was no significant difference between Gwangneung Forest and the urban forest. BTEXS concentrations were ranked as traffic island>residential park>Hongneung Forest>Gwangneung Forest>Mt. Cheonjang. Traffic island and residential park showed high levels of BTEXS depending on the inflow of vehicles. The difference in concentration by time was significant for the traffic island in particular. Pollutant levels in Hongneung Forest were as low as in Gwangneung Forest. Conclusion: The concentrations of phytoncides and BTEXS were different by types of urban green space, and the potential for health and hygiene of urban forests were able to be investigated. This study is expected to provide as basic data for the creation of urban forest spaces in the future.

Although many studies have been conducted on techniques and effects that can be applied to forest meditation in domestic forest healing meditation research, there has been little research on the space where forest meditation takes place. Nevertheless, a meditation space is not just a place concept but a forest environment element responsible for the healing function of a forest, i.e., a place containing healing factors, and can be an essential clue to the healing mechanism. Therefore, to determine whether a healing forest meditation space is suitable for meditation, this study selected the attribute items of the meditation space using the Delphi expert survey and then surveyed the user satisfaction of the healing forest meditation space using the IPA (Importance Performance Analysis) technique. The survey was conducted from August to November 2022, targeting 315 adults who used the forest meditation space at the National Center for Forest Therapy, the Saneum Healing Forest, and the Jathyanggi Pureunsup Arboretum in Gyeonggi Province. The result of the IPA analysis showed the average satisfaction with the forest meditation space was relatively high at 4.33 points on a 5-point Likert scale (4.33 points for the National Center for Forest Therapy, 4.34 points for the Saneum Healing Forest, and 4.37 points for the Jathyanggi Pureunsup Arboretum), indicating that the three healing forest meditation spaces were suitable for forest meditation. Satisfaction with the "Sounds of nature" was high in all three forests. On the other hand, all three forests showed a relatively low satisfaction with "Quietness," indicating it to be a priority problem to be addressed. Also, an open-ended questionnaire survey showed that the mediation space's natural elements, such as natural sounds, scenery, air, forest spaces, and scents, had a higher positive impact on meditation satisfaction than artificial elements, such as facilities. Therefore, it is essential to secure sound resources such as the sound of water and birds around the meditation space, and it is also necessary to consider ways to create a meditation forest in an independent area to avoid encounters with visitors and allow only participants in the forest healing meditation program to enter to increase satisfaction with forest meditation.

This study was conducted to identify the appropriate space requirements for forest healing program for physical and mental health care of female cancer survivors in their 40s and 60s. From September to November 2023, 12 cancer survivors were surveyed at Chungnam National University Forest and Daejeon Healing Forest. One Forest Therapy instructor and two researchers conducted a forest healing program once a week for eight sessions of two hours each, Perceptions and satisfaction with the program and space were assessed using pre and post program questionnaires, and the effect of participation in the forest healing program on mood status was evaluated. The satisfaction survey results were supplemented by qualitative studies conducted through post-interviews. Result of the analysis showed that the satisfaction of the participants was very high (4.8/5.0). There was a notable increase in vigor and a decrease in total mood disturbance after participation in the program. Toilets and water facilities (11), tool boxes (9), pest control facilities (3), deck facilities (3), forest hut (3), electrical outlets (2), shade shelters (2), and shoe hairy (1) were proposed as required facilities for cancer survivors. This study demonstrated that the forest healing program is effective in reducing distress in female cancer survivors in their 40s and 60s and appropriate facility standards for the forest healing space are needed to increase the satisfaction of cancer survivors.

Background: We measured the weight characteristics, intercellular space volume as a proportion of root volume, and quantities of the functional component in Angelica gigas Nakai, collected from four cultivation areas in Pyeongchang, including Tapdong-ri and SangjinBu-ri, and tested the results for correlations. Methods and Results: Dry weight was the highest in the Tapdong-ri group ($13.37{\pm}0.13g$) and the lowest in the SangjinBu-ri group ($11.90{\pm}0.57g$). The percentage of intercellular spaces within the roots, determined by micro-CT camera, was the highest in the Tapdong-ri group ($6.44{\pm}0.76%$) and the lowest in the SangjinBu-ri group ($9.01{\pm}2.15%$). The quantity of functional components were the highest in the Tapdong-ri group ($116.13{\pm}9.53mg/g$) and the lowest in the SangjinBu-ri group ($99.77{\pm}23.23mg/g$). Conclusions: The dry weight of A. gigas significantly correlated with the volume and percentage of intercellular space. An increase in the dry weight resulted in a negative correlation between the volume and ratio of the intercellular spaces. The volume of intercellular space correlated negatively with levels of the functional components, this was significant in the case of the nodakenin, decursin and decursinol angelate content (p < 0.016).

We have researched the image of different forest species by asking those who use these forests how they feel when enjoying them for their various purposes. We surveyed five different forest areas, these were a pine forest a korean pine forest a cypress forest a broad leafed forest and a mixed forest. We asked 806 people how these forests made them feel and what they thought was the image of these forests. We offered them a choice of 18 pairs of adjectives to describe how they felt. We used the SD Scale and discovered 4 different factors. A feeling of comfort and freshness and a feeling of order and space. There was also a feeling of intimacy with nature. Each forest gave out its own feeling and image. comfort and freshness was felt by those in the pine forest, the korean pine forest, the broad leafed forest and the mixed forest. A Feeling of order and space was felt in the korean pine forest. Intimacy was felt in the pine forest, broad leafed forest and the mixed forest.

Development of forest garden for city dwellers utilizing green space within urban area is nowadays highly regarded as a means to invigorate city and to raise living standard for city dwellers. Thus, development of forest garden has become pressing and important agenda for city governments. Promoting forest garden to solve many environmental and social issues city governments face today requires evaluation criteria to determine whether target green space is suitable to serve as forest garden. In this respect, we believe that evaluation of values of forest garden from previous studies can serve as foundation for developing evaluation index for forest garden. Thus, we aimed to develop evaluation criteria for values of forest garden. First, various evaluation criteria collected from previous studies were assessed by expert groups. Then, the result was studied through AHP technique and we developed evaluation criteria for forest garden based on such result. Especially, evaluation criteria were divided into main and sub-levels for more detailed and precise evaluation system.

In this study, we observed air temperature to make clear that land coverage condition and forest form has a certain relationship to air temperature in a day in various green space. And with revolution analysis, interpreted relationship of air temperature distribution in the green space, of land coverage rate and air temperature, of volume of tree and temperature. With this experimental result, propose green plan, taking into consideration lower effect of air temperature. In this result lower zone is formed in forest and water area, higher zone is done in paved surface and barren ground. And arbor＋subarbor area, water area sur-rounded forest and small river is formed relative lower air temperature. In my opinion to promote efficiency lower air temperature area, it is need to make water area surrounded forest, to make forest form lower air temperature 2∼3 layer forest. Lower air temperature effect is in order of arbor, subarbor, shrub and is proportioned increasing of tree.

The purpose of this study is to select indicators by a methodical approach and to establish a functional assessment system as a basic study for planning and constructing green space of forest. The types of green space were divided into 6 classes based on theoretical reviews of literature and the functions of green space were restricted to 'nature-ecological function', 'environment-control function' and 'usage function'. As a result of the selection of indicators, 35 indicators were initially selected by theoretical review and these indicators were reduced to 29 through brainstorming. Also, these indicators were classified into three functions such as 12 indicators (nature-ecological function), 8 indicators (environment-control function), 6 indicators (usage function) by analysis of suitability. According to the result of selection of the optimum indicators using MCB (Multiple Comparisons with the Best treatment) analysis, the optimum indicators of 7, 5, and 4 respectively by each function were selected for forest green space. The results of AHP (Analytic Hierarchy Process) for the establishment of the assessment system in forest, the weight of nature-ecological function was evaluated highest at 0.558, while the weight of environment-control and usage function were calculated at each 0.277, 0.165. 'Naturality (0.189)', 'Carbon sink (0.235)', and 'Accessibility (0.354)' among indicators showed highest by each function. The weight of indicator and assessment system may be used as a valuable guideline in case of assessing synthetically green space within urban planning.

This study attempt to evaluate the recreation space(two patterns ; one is open space ; forest, water-front space and free open space, the other recreational fercilities) located in the natural area based on clarifying the relationship between the physical conditions of these spaces and human response(users' cognitive evaluation and users' activity pattern). On this standpoint it was proceeded to analyses of the information which was collected by interviews to users who were in this open space at the natural park of Osaka Prefecture. Through this study, the results were summarized as follows ; 1) Forest and waterfront space are considered to be a basic factor of the composition in natural recreation areas. There was difference on the recreational value depending on condition of forest composition. The hardwood-forest apparently high in its efficiency. 2) Free open space is a definite recreational space surely wide in its scope of active of recreational use. The site should be setted up considering the plants conditions around and geographical features according to the recreational activities, and the ground cover should be well controlled. 3) The recreational facilities in natural settings such as the sightseeing tower, the insect display hall, and the camp site appeared to produce low value as a recreational space. It was desirable that recreational activities be allowed within the scope. Consequently, we should carefully consider environmental capacity and landscape to designing these spaces 4) Traditional history and cultural properties are recognized as part of recreational resource as and also as essence of the compositions. So continuos care and proportion of history and cultural properties should be guaranteed.
