This study investigated the effects of participation in a forest therapy program on ego-resiliency and interpersonal relationships to strengthen the independent capabilities of children requiring protection. The participants were divided into two groups: the experimental group (n=87; age, 16.40±1.90 years) and control group (n=90; age, 16.97±1.39 years). The study was conducted from July to August 2020. The experimental group participated in a forest therapy program operated by the National Center for Forest Therapy, Yeongju, for 2 nights and 3 days, whereas the control group lived routine life. The participants' ego-resiliency and interpersonal relationships were tested at the beginning and end of the forest therapy program. In the experimental group, ego-resiliency was improved and interpersonal relationships were significantly altered. Therefore, forest therapy programs may serve as effective interventions that can positively affect the social adaptation and growth of protected children into healthy adults.

Iriai an Indigenous forest management system in Japan from the viewpoint of "common pool resources" was a success resilient institution and resulted with sustainable production system and environmental conservation. This study was conducted in Osawa of the Nagano prefecture through group discussions, field observations and an in-depth field survey. Osawa Property Ward Forest is managed under the concept very much similarly to traditional "Iriai". This study firstly examined the changes of collective forest management system in terms of awareness and interest in forest management; forest management activities; role of forest; and collection of forest products. Then it analyzed the current threats for collective forest management have been identified as: land abandonment due to loss of benefits and lack of active community participation; deterioration of forest environment particularly the micro-climate and aesthetic values; conflict with local government authorities restraining the use of money in property ward forest and conflict with outsiders on damping of the garbage. Community cantered forestry management rules; livelihood contribution; protection of environment; local initiatives for protection and economic activities are the prevailing opportunities for collective forest management. The main requirements for revitalization of collective forest management are explained as local reciprocity; imposition of community based forest rules; encouraging local innovations; and building partnerships with stakeholders. Collective forest management system addresses the limitations of conventional forestry models, which had invalidated traditional 'iriai' institutions, and key to restoring sustainable use of forest and environmental resources. Cross-institutional collaborations together with responsibilities of local communities would ensure the revitalization of forest resources.

본 연구에서는 남북한 산림과학기술협력에 대비하여 북한의 산림과학 관련 학술지 분석을 통해 북한 산림과학 연구 동향을 분석하였다. 한국과학기술정보연구원(KISTI) 북한과학기술네트워크(NKtech)의 소장 논문을 대상으로 우리나라 국가과학기술표준분류체계를 토대로 임학 관련 주제어를 검색하여 분석 대상 논문을 수집하였다. 총1,389편의 논문을 수집하였으며 북한 산림업 계획 지표를 토대로 산림조성, 보호 및 이용 분야로 분류하여 각 분야별 북한 산림과학 연구 동향을 분석하였다. 2012년 김정은 집권 이후 산림조성 분야에서는 나무모 기르기(양묘)와 임농복합경영 분야의 연구 활동이 활발하였으며 사름률(활착률)을 강조하고 있었다. 산림보호 분야에서는 산림병해충에 대한 노력이 크며 임농복합경영과 풀뚝다락밭을 통해 토양침식을 감소시키려는 노력을 하고 있는 것으로 판단된다. 산림이용 분야에서는 주로 펄프/종이와 버섯 분야에서 연구가 활발함을 확인하였다. 산림경영 분야에서는 '생태정보' 분야의 활동이 눈에 띄게 나타났으며 탄소감축 노력을 확인할 수 있었다. 북한 산림과학 동향을 살펴본 결과 북한의 산림에 대한 관점이 기존의 '자연 개조' 대상에서 '자연 보호'를 함께 수반하는 관리의 대상으로 변화되었다고 보여 진다. 향후 세부 분야별 남북 산림과학 기술 비교 연구와 시기별 북한의 정책방향이 연구 방향에 미친 영향에 대한 분석을 진행할 계획이다. 특히, 남북산림협력사업을 원할히 하기 위해서 남북산림용어사전 편찬이 필요할 것으로 사료된다.

Since July 2005, survey of chestnut ink disease was carried out in chestnut stands located at southern parts of Korea. Dead chestnut trees showing inky ooze on necrotic trunks were found in two different locations. In order to isolate and identify the causal fungus, infected tissues and soil samples around dead or dying trees were collected and placed on Phytophthora-selective medium. Rhododendron and chestnut tree leaves were used as a bait to isolate the fungus from soil samples by attracting zoospores in soil suspensions. On V-8 culture medium, the isolates produced homothallic oogonia with protuberances ($34.0-46.2{\times}21.9-26.7{\mu}m$) abundantly, but did not produced sporangia. Mass production of sporangia was possible by immersing agar plugs with actively growing mycelium in the creek water at $18^{\circ}C$ for 3 days. Sporangia were papillate, and ovoid to obpyriform ($17.0-38.9{\times}14.6-29.2{\mu}m$) in shape. Comparison of the ITS sequences revealed that the isolates had 100% identity to the P. katsurae isolates from Japan and New Zealand and 99.6% identity to other P. katsurae isolates. All of the examined isolates from Korea were completely identical to each other in ITS sequence. Numerous sporangia were formed in filtered as well as unfiltered creek water, but no sporangia formed in sterilized distilled water. Light induced sporangia formation, but has no influence on oospore formation. Amendments of ${\beta}$-sitosterol in culture media have no significant effect on mycelial growth but significantly stimulate oospore and sporangia formation.

In order to evaluate a feasibility of industrial art use of veneer such as cylindrical laminated veneer lumber, the veneers of 4 species of Korean pine, radiata pine, yellow poplar and Japanese cypress were natural dye-colored and clear finished. Natural dyes were red color originated from sappanwood, blue color from polygonum indigo, and yellow color from Amur cork tree and gardenia. the clear coats of crack seal clear and UV protection oil were applied on the dyed veneer. The dyeing and finishing characteristics through fading test were summarized as follows; In non-dyed and non-finished Korean pine veneer, lightness was decreased and yellow and red hues increased after fading test. In natural dyed- and finished-veneer, color difference of gardenia-mixed Amur cork tree was generally highest, and that of polygonum indigo was lowest. Compared to non-treatment of veneers of Korean pine and yellow poplar, color difference decreasing effect by finishing was shown in crack seal clear and UV protection oil. In addition, UV protection oil was more favorable than crack seal clear with more decreased color difference. In result, maximum values of color difference after fading for 8 days were recorded about 16 to 20, which are remarked 'very much' of 12.1 or more when reviewing with 'National bureau of standards unit in USA'.

The legal basis for the systematic prevention and response to landslide hazards, and the rehabilitation of landslide-hit areas, was established through the amendment of the Forest Protection Act in August 2012. The most noticeable amendment to the Act is the inclusion of clauses associated with the designation and management of landslide-prone zones (including debris flow-prone zones). In this paper, we (1) introduce the clauses related to the designation and management of landslide-prone zones that were included in the amended Forest Protection Act, (2) examine their significance by reviewing the present status of related domestic laws and structural countermeasures such as sediment check dams for sediment-related disaster prevention, and (3) suggest the future directions of the procedure for the designation and cancellation of such zones, and their maintenance and institutional aspects. The establishment of an institutional device for the designation and management of landslide-prone zones has great significance in the aspect of (1) the establishment of a comprehensive management and prevention system for potential landslide-prone zones in forested areas where the hazard risk has been poorly recognized as compared with the flood risks in lowlands, and (2) the establishment of the basis for overcoming the limits of structural countermeasures according to limited budgets. To develop the designation and management system for landslide-prone zones, not only must present problems be addressed, but a cooperation system between the administration and local residents must also be established.

This study was conducted to obtain the information of distribution, protection and management for mammal species in fragmented forest areas around the road from June 2002 to May 2003 in 9 study sites of Baekdugdaegan mountains, Korea. Field signs of twelve mammals, moles Molera robusta, Korean hares Lepus coreanus, Manchurian chipmunk Tamias sibiricus, red squirrels Sciurus vulgaris, Korean racoon dogs Nyctereutes procyonoides, Siberian weasels Mustela sibirica, badgers Meles meles, otters Lutra lutra, Bengal cats Felis bengalensis, wild boars Sus scrofa, water deer Hydropotes inermis and roe deer Capreolus pygargus were recorded in this study. There were no differences in total number of species between 50 m areas and 50-100 m areas from road in snow and non-snow season. Number of mammals' field signs were different in non-snow season between both areas. Red squirrels and Siberian weasels were more abundant in 50 m areas, and Korean hares and Manchurian chipmunks were in 50-100 m areas. Habitat using pattern of mammal species may be affected by the road. Reasonable road construction and maintenance would be needed for protection and management of wildlife and their habitats.
