숲 공간의 영향에 대한 많은 연구들이 있는 반면 시간요인에 대한 연구들은 부족하다. 공간과 시간은 동시적으로 상호간에 영향을 미치기 때문에 공간요인에 의한 영향들은 시간에 의해 변화할 수 있다. 본 연구는 숲에서 보낸 시간의 4가지 요인들(체험, 몰입, 건강지각과 심리내적 인식)에 대한 영향에 초점을 두었으며, 2014년 4월부터 10월까지 설문을 통해 이루어졌다. 설문지는 체험 (LE), 몰입(FL), 건강지각(HP)과 심리내적인식(IPP)으로 구성되었다. 대상자들은 충청남도 이북지역에서 살고 있으며 생태 숲해설 과정이나 생태교육과정에 있는 사람들로 40-70세였다. 이들은 또한 1년에서 20년에 이르는 숲관련 경력을 가지거나 일을 하고 있는 사람들이었다. 체험, 몰입, 건강지각과 심리내적 과 같은 요인들은 숲에서 보낸 시간의 영향을 받는 것으로 나타났으며, 이 요인들은 통계적으로 유의한 수준에서 숲에서 보낸 시간에 따라 증가하는 것으로 밝혀졌다. 이 연구는 산림치유프로그램을 기획하는 사람들뿐만 아니라 산림치유를 공부하는 사람들에게도 유용할 것이다. 숲에서 보낸 시간이 체험, 몰입, 건강지각과 심리내적 인식에 영향을 주기 때문에 이 점을 산림치유프로그램에서 고려해야 한다.

Purpose: This study was performed to determine the physical and psychological effects of an urban forest-walking program for office workers. For many workers, sedentary lifestyles can lead to low levels of physical activity causing various health problems despite an increased interest in health promotion. Methods: Fifty four office workers participated in this study. They were assigned to two groups (experimental group and control group) in random order and the experimental group performed 5 weeks of walking exercise based on Information-Motivation-Behavioral skills Model. The data were collected from October to November 2014. SPSS 21.0 was used for the statistical analysis. Results: The results showed that the urban forest walking program had positive effects on the physical activity level (U=65.00, p <.001), health promotion behavior (t= - 2.20, p =.033), and quality of life (t= - 2.42, p =.020). However, there were no statistical differences in depression, waist size, body mass index, blood pressure, or bone density between the groups. Conclusion: The current findings of the study suggest the forest-walking program may have positive effects on improving physical activity, health promotion behavior, and quality of life. The program can be used as an effective and efficient strategy for physical and psychological health promotion for office workers.

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.

The purpose of this study is to predict Trophic Diatom Index (TDI) in tributaries of the Han River watershed using the random forest algorithm. The one year (2017) and supplied aquatic ecology health data were used. The data includes water quality(BOD, T-N, $NH_3-N$, T-P, $PO_4-P$, water temperature, DO, pH, conductivity, turbidity), hydraulic factors(water width, average water depth, average velocity of water), and TDI score. Seven factors including water temperature, BOD, T-N, $NH_3-N$, T-P, $PO_4-P$, and average water depth are selected by the Correlation Feature Selection. A TDI prediction model was generated by random forest using the seven factors. To evaluate this model, 2017 data set was used first. As a result of the evaluation, $R^2$, % Difference, NSE(Nash-Sutcliffe Efficiency), RMSE(Root Mean Square Error) and accuracy rate show that this model is compatible with predicting TDI. To be more concrete, $R^2$ is 0.93, % Difference is -0.37, NSE is 0.89, RMSE is 8.22 and accuracy rate is 70.4%. Also, additional evaluation using data set more than 17 times the measured point was performed. The results were similar when the 2017 data set were used. The Wilcoxon Signed Ranks Test shows there was no statistically significant difference between actual and predicted data for the 2017 data set. These results can specify the elements which probably affect aquatic ecology health. Also, these will provide direction relative to water quality management for a watershed that must be continuously preserved.

It is important to measure the height of trees as an essential element for assessing the forest health in urban areas. Therefore, an automated method that can measure the height of individual tree as a three-dimensional forest information is needed in an extensive and dense forest. Since airborne LiDAR dataset is easy to analyze the tree height(z-coordinate) of forests, studies on individual tree height measurement could be performed as an assessment forest health. Especially in urban forests, that adversely affected by habitat fragmentation and isolation. So this study was analyzed to measure the height of individual trees for assessing the urban forests health, Furthermore to identify environmental factors that affect forest growth. The survey was conducted in the Mt. Bongseo located in Seobuk-gu. Cheonan-si(Middle Chungcheong Province). We segment the individual trees on coniferous by automatic method using the airborne LiDAR dataset of the two periods (year of 2016 and 2017) and to find out individual tree growth. Segmentation of individual trees was performed by using the watershed algorithm and the local maximum, and the tree growth was determined by the difference of the tree height according to the two periods. After we clarify the relationship between the environmental factors affecting the tree growth. The tree growth of Mt. Bongseo was about 20cm for a year, and it was analyzed to be lower than 23.9cm/year of the growth of the dominant species, Pinus rigida. This may have an adverse effect on the growth of isolated urban forests. It also determined different trees growth according to age, diameter and density class in the stock map, effective soil depth and drainage grade in the soil map. There was a statistically significant positive correlation between the distance to the road and the solar radiation as an environmental factor affecting the tree growth. Since there is less correlation, it is necessary to determine other influencing factors affecting tree growth in urban forests besides anthropogenic influences. This study is the first data for the analysis of segmentation and the growth of the individual tree, and it can be used as a scientific data of the urban forest health assessment and management.
