The changes of forest degradation in North Korea have closely been related to political, economic and social conditions at all different times. The deforestation by local people for their livelihood has been accelerated when the recession has been worsened due to the 1990's collapse of socialism and the years of natural disasters, and the fall of the centralized and planned economy system. The serious recession in the 1990's has brought many changes in the North Korean society since the 2000's. Not only the underground economy, but also the market in which personal trades are occurred have been expanded as the distribution system of the planned economy system had fallen. In addition, even many state institutions have also increased timber harvest for export to acquire insufficient foreign currency. Eventually, North Korea felt the limits of utilization of forest resources under socialism then started to seek measures to restore devastated forest, while realizing the need of support from the international society. Therefore, some NGOs of South Korea started to give financial support on building tree nurseries in which seedlings for planting are produced to help the rehabilitation of the degraded forests in North Korea. Therefore, Planning of the basic directions for forest rehabilitation programs considering to economic and social conditions of North Korea are needed based on the successful rehabilitation experience of South Korea in the 1970's. First of all, relationships which was built after collapse of centrally planned economy between districts, businesses and workers must be consider to rehabilitate forests in North Korea. Secondly, due to the nature of forest rehabilitation projects this is very needs voluntary participation of resident for a long time, and then forest rehabilitation projects can create jobs for local resident, they can obtain continuous income on the forest rehabilitation projects field in order to promote resident's work in forest rehabilitation projects. Thirdly, the rate dependence on forests of the residents living must keep the level down by rural development projects going side by side with forest rehabilitation projects. Fourthly, use of exsisting forest management system in North Korea is also needed to ensure administrative power and labor for grand scale plantations in a short period of time. Meanwhile after the success of Forest Rehabilitation, it is very important to improve exsisting forest management system.

Objectives The purpose of this study is to understand the research trend of reports on forest therapy so far and analyze the Korean medicine therapy being applied in forest therapy programs. Methods We ran a keyword search on domestic databases with the following keyword 'forest therapy, forest healing, forest treatment, recreational forest, forest bath, forest experience'. The search took place in December 2014 and there was no limit to search time. A total of 334 forest therapy articles have been selected. Results The number of research on forest therapy continued to rise from 1985, with 334 articles being published from 84 journals. When those 188 articles were sorted by their contents and methods, except 146 articles of survey on simple satisfaction, recognition and visting, 94 were clinical studies, 79 were literature studies, 15 were experimental studies. Of the 94 clinical researches, there were 52 CCTs (Controled Clinical Trials), 39 ODs (efficacy studies with either a controlled or an Other than controlled Design) and 3 RCTs (Randomized Clinical Trials). Among the clinical researches, there were a total of 21 studies that used Korean Medicine programs, and meditation was the most popular, being used in 18 studies. Herbal food and tea therapy and Qigong were used in 3 studies each, and Korean medicine music programs were used in 2 studies. Conclusions A systematic and standardized Korean medicine forest therapy program must be developed, and based on the program, more research treating diseases should be conducted.

Purpose: The purpose of this study is to analyze community-based health promotion program for school-aged children and program using forest. Methods: Seventeen health promotion programs focused on school-aged children from Community Health Plan were selected to analyze after assembling 227 of the 5th National Community Health Plans. The analysis duration was from 2012 July to November. Results: Among 17 programs, the health promotion program targeting school-aged children were included in 16 programs except one program focusing on community- orientated rehabilitation program. Eight health promotion programs using forest in 7 different areas were found. The majority of the community-based health promotion programs were focused mainly on smoking cessation, obesity, physical activity, nutrition, mental health programs. Furthermore, there was a limitation of programs utilizing forest as a health promotion resource and most of the programs using forest were located in Jeollanamdo and focusing mainly on atopy prevention and treatment. Conclusion: The importance of this study is that it analyzed nation-wide community health plan systematically, and analyze community-based health promotion program targeting school-aged and the program using forest. The results of the analysis can be used as baseline data for developing physical and mental health promotion programs using forest targeting school-aged children.

The purpose of this study was to draw policy implications for the development and expansion of Korea's forest ODA through investigating the perceptions of stakeholder on the fields that contributed the development of forestry in Korea and would have competitiveness in developing countries and priority fields for Korea's forest ODA. For this, the survey was conducted for 248 subjects from the general and expert stakeholder groups. Chi-square test in cross analysis, independent sample t-test, ANOVA and Duncan test were conducted to compare the difference of perceptions by group. The whole general and expert groups consider that 'forest conservation and rehabilitation' contributed to the development of Korea's forestry most and consider its global competitiveness most high. Comparing expert groups, ODA experts evaluated the competitiveness of 'capacity building for policies, institutions and research' higher than the forestry experts. For priority fields of Korea's forest ODA, general groups perceived 'management of CERs' and 'conservation of biodiversity' most important, showing the clear difference in perception compared to that of experts. In Conclusion, for the effective forest ODA of Korea, the effort to fill the gap between the general and expert groups needs to be made, as well as developing forestry capacity building programs to cope with the fields such as climate change adaptation and biodiversity conservation, which is newly required in a global society, in addition to using the past experience of forest rehabilitation in Korea. It will be useful for the rehabilitation of North Korea's forest in the future.

Enrichment planting is commonly used for increasing the density of tree species in secondary forests and one of forest rehabilitation programs in Lao PDR. This study aimed to determine the performance of five native species in enrichment planting using different canopy opening treatments, and to examine the suitable species and silviculture techniques applicable to a logged-over forest in Lao PDR. Results of the study showed that only crown height had significant difference among species and planting treatments. The survival rate and crown diameter were significantly different by species, but not by planting treatments. However, root collar diameter (RCD) and height of seedlings showed significant differences among planting treatments. Among the study species, Hopea odorata and Dalbergia cochinchinensis showed significantly higher survival rate and height growth, indicating their suitability in enrichment planting for rehabilitation of forest in Lao PDR. The results also suggested that 2 m width line planting stimulated RCD growth, but wider line planting, such as gap planting, promoted height growth of seedlings.

The effectiveness of rehabilitation programs for coal mining spoils in Samcheok, Jeongsun, and Mungyung were evaluated based on the physicochemical properties of soil in the rehabilitated areas. These spoils were reclaimed by introducing plants such as black locust (Robinia pseudoacacia), pitch pine (Pinus rigida), birch (Betula platyphylla var. japonica), alder (Alnus hirsuta), bush clover (Lespedeza cyrtobotrya), and grass (Lolium perenne) in planting beds covered with forest soil. In the surface soil, the pH, organic matter, total N, available P, and exchangeable Ca showed significant changes over the years after reclamation. The pH and exchangeable Ca content decreased exponentially over time, whereas organic matter increased linearly and total N and available P increased exponentially. Changes in the physicochemical properties of subsurface soils displayed a different pattern. There were significant changes over time in the organic matter, available P, and exchangeable Ca and Mg contents of the soil. Organic matter increased logarithmically with years since rehabilitation and available P increased exponentially. Meanwhile, exchangeable Ca decreased exponentially, and Mg decreased logarithmically. The changes in the subsurface soil were not as dramatic as those in the surface soil. This result suggests that the ameliorating effects of the establishment and growth of plants more pronounced on the surface soil layer. Stand ordination data showed different relationships with time since rehabilitation in the early and later stages of the rehabilitation process. In the early stages of rehabilitation, stands tended to be arranged in the order of reclamation age. However, in the later stages, there was not a clear relationship between reclamation age and vegetation characteristics. This result suggests that soil amelioration is required for the early stages, after which an autogenic effect becomes more prominent as the vegetation becomes better established.

Restoration is the process of reducing or reversing damage to an ecosystem so that it can function in its original manner. However, many restoration programs do not achieve this. In the Nakdong Estuary, the largest migratory nesting site in the center of the East Asian-Australasian flyway, an estuarine barrage was constructed in the 1980s that required site restoration following its completion in 1987 and the expansion of several large industrial complexes(Noksan and Jangrim) and a residential development(Myeongji). The goal of the restoration was to restore the function of the wetland to its pre-disturbance state. To achieve this, a restoration program was designed consisting of three stages. The first stage(1993-1995), saw the construction of three artificial wetlands(Shinhori, Daemadeung, and Eulsuk), the second(2003-2005) involved the dredging and returning of farmed lands to their natural state, and the third(2008-2012) focused on the rehabilitation and vegetation development of the wetlands. However, the project has not achieved all of the desired goals, and it is an example of the lapses in ecological restoration following anthropogenic disturbance. Issues that resulted in an incomplete restoration included the timing of the stages, noncompliance with the restoration plan, not directly monitoring the restoration or continuing the monitoring following completion of the development project, and the political subversion of the restoration plan. For the success of the restoration plan, it is necessary to avoid mistakes such as inconsistent monitoring, unequal levels of stakeholder involvement, and political interference.
