8주간 옻나무 추출액을 섭취하며 운동을 병행하였을 때 혈중 지질 성분, 인슐린 저항성에 미치는 영향에 대해 연구하였다. 6주된 SD계 수컷 쥐를 대상으로 CON(대조군), RVS(추출액 섭취군), EXE(운동군), 그리고 RVS-EXE(추출액 섭취와 운동 병행군)로 구분하였다. 각 집단의 체중은 EXE(202%)와 RVS-EXE(203%)가 CON(253%)과 RVS(239%)에 비해 통계적으로 유의하게 낮은 증가를 보였다. 저장지방은 옻나무 추출액 혹은 운동에 의해 유의하게 감소하는 것으로 나타났다. 혈중 지질성분은 RVS와 RVS-EXE에서 CON에 비하여 통계적으로 유의하게 개선되는 것으로 나타났다. 혈중 글루코스는 CON에 비하여 다른 집단에서 유의하게 낮은 것으로 나타났으며, 인슐린 역시 동일하였으나, RVS-EXE에서 유의한 상승작용이 나타났다. HOMA 지수는 인슐린과 동일한 결과를 나타내었다. 이와 같은 결과를 종합해 볼 때 옻나무 추출액 섭취와 함께 운동의 병행은 저장지방을 감소시키고 혈중 지질을 억제하며, 인슐린 저항성을 개선시키므로 대사증후군 즉, 당뇨병, 비만, 고지혈증 등을 효과적으로 억제할 수 있다는 점을 시사한다.

This study was carried out to create a master plan for an urban eco-forest, including concepts of forest restoration, forest management, and nature education. The concept of an urban eco-forest is different from the original eco-forest, which pursues the conservation of native species in their habitats, using the resources of special plants, etc. The study site was a hill (128m) managed as an urban natural park. Citizens have usually used the park for fitness purposes, as a place for outdoor exercise early mornings on weekdays and holidays. The result of a questionnaire survey showed that the users knew about the eco-forest, and they wanted to participate in the nature education programs. The flora and actual vegetation were weak about conservation of native species on the site. The framework of the plan consisted of development of the ecological forest and forest restoration, and allowed for recreation and the experience of nature, according to the concepts of the urban eco-forest. The landscape was divided into the experience zone of biodiversity, the experience zone of a valley ecosystem, the forest restoration zone, and the recreation and experience zone in nature. Based on this framework, detailed programs and theme areas were planned, as were forest restoration models and planting plans.

Physical activities in the forest environment stimulate the parasympathetic nervous system of humans and have positive effects on the autonomic nervous system as well as moods and emotions. However, there are almost no studies on the benefits of exercise in the forest environment for patients with myocardial infarction. The aim of this study was to investigate the effects of 15-minute single session walking by myocardial infarction patients in the forest and urban environment on the physiological and psychological states. The heart rate variability was measured in 10 patients with myocardial infarction to assess physiological state after single session walking for 15 minutes in the forest environment and urban environment. In order to evaluate the psychological state, a profile of mood scale (POMS) and semantic differential (SD) questionnaire were used. The results of this study showed that 15-minute single session walking in the forest environment activated the parasympathetic nervous system of adult myocardial infarction patients more than 15 minutes of single session walking in the urban environment, and also made them feel more positive in terms of the POMS and SD. Therefore, this study suggests that even single session walking in the forest environment can positively influence the physiological and psychological states of adult heart disease patients and may also contribute to health care.

The realities of Climate change and its untold implications on the livelihood of man are no longer new worldwide. In attempts to subdue the negative implications of Climate change scenario globally, several measures have being suggested and being put in place. One of such measures is urban reforestation especially in the developing nations where forest resources have extremely and uncontrollably exploited. Most of cities in developing nations are almost devoid of regularly maintained trees for whatever purpose. Thus, the enormous roles which urban tree performs are lacked in most cities. In order to subdue excessive heat in cities arising from exposure of urban land areas urban reforestation exercise needs to be embarked upon. The investigation was carried out through desk studies and review of relevant publications to examine what it entails to have a sustainable reforestation programme in cities. The study revealed that several factors need to be taken into consideration if sustainable urban reforestation will be achieved, especially in developing countries. These factors include urban soil nutrients status investigation, appropriate tree type study, public perception about the tree types, relevant legal instrument to achieve successful reforestation exercise in cities among others were found to be salient to this exercise. Urban reforestation has enormous potentials to subdue Climate change consequences, including urban renewal if adequate provision is made for its sustainability, especially in developing countries. To ensure this is realized it is recommended that relevant ministry/agency could be put in charge for the maintaining, cutting and replanting of urban tree and all that are involved in urban tree sustainability.

The purpose of this study is to provide information on a forest healing environment using the analysis of nature volatile organic compounds (NVOCs) and thermal comfort in Chungnam National University Experimental Forest, with the aim of using the Experimental Forest as a healing environment for health promotion. We analyzed NVOCs and thermal comfort of Chungnam National University Experimental Forest measured on September 12^th, 2021. As a result of the NVOC analysis, a total of seven substances were detected, mainly including alpha pinene and beta pinene. The detection amount for each time period was highest at the time of sunset. The thermal comfort was analyzed by time-dependent changes and changes according to clothing and exercise amount. The results showed that the predicted mean vote of the experimental forest is within the range of 'slightly cool' and 'slightly warm' sensation, and thus a comfortable thermal environment could be controlled by the amount of clothing and activity. Based on the analysis, this study provides information on the healing environment of the experimental forest at Chungnam National University. It also indicates that the forest can be used as a health promotion and healing environment with thermal comfort by composing a physical activity program of appropriate intensity for each time period.

The purpose of this study was to examine the potentiality of urban forest roads as an environment for enhancing physical fitness. Six male university students participated in the study as subjects. The subjects walked on an urban forest road for 30 minutes. As a control experiment, they also walked on a national park trail for 30 minutes. Subjects' heart rates were monitored during the walks to calculate the ratio of the average time their heart rates were within the target range (from 60% to 80% of the maximal heart rate) for Enhancing Physical Fitness. After the walks, images of the spaces were analyzed using the semantic differential (SD) method. During the walk on the urban forest road, subjects' heart rates were within the target range 63.3% of the time, and lower than the target range 36.7% of the time. During the control experiment on the national park trail, subjects' heart rates were within the target range only 23.3% of the time, and higher than the target range 76.7% of the time. From the spatial perception evaluation using the SD method, subjects' comfortable and natural feelings when they were on the national park trail were significantly greater than when they were on the urban forest trail, but there were no differences in terms of other SD descriptors, such as friendliness and likeability. The results of our study indicate that the urban forest road provides a good environment for walking to enhance physical fitness. Although not as close to nature as national park trails, urban forest roads offer similar natural environments and have a high potentiality for serving as leisure spaces for urban residents who seek physical activities.
