This study was tried to find out the applicability of decision support system for forest land use conversion, which developed based on algorithm for forest land-use conversion. Decision support system developed by Ministry of Safety Administration is free from the existing licensed laws omission. And it made the input requirements for each value of the final result so that you can determine whether the permit was available by the laws and regulations related to the algorithm for forest land use conversion. Also, in order to do field surveys, equal sampling interval method is used to extract samples for the operability by comparing and analyzing the actual area. As a result, 88 areas of total 100 areas are able to get permission by the decision support system for forest land use conversion, and it means if there is enough data with sufficient research, it can make the availability permits easily.

본 연구는 우리나라 국유림(國有林)의 시업계획(施業計劃)의 체계화(體系化)와 바람직한 발전방향(發展方向)의 수립에 기여하고자 일본(日本) 국유림(國有林)의 시업계획(施業計劃) 방침(方針)에 대한 사적(史的) 전개과정(展開過程)을 검토, 고찰하였다. 전전기(戰前期) 일본(日本)의 국유림(國有林) 시업(施業)은 토지순수확(土地純收穫)과 삼림순수종(森林純收種) 합앙체계(合仰體系)의 시업방침(施業方針)에 의해, 주로 작업급(作業級) 및 벌채렬구(伐採列區)를 수반한 소면적(小面積)의 개벌작업(皆伐作業)과 간이한 면적평분법(面積平分法), 그리고 절충적인 중장기(中長期)의 륜벌기(輪伐期)가 채용되어져, 법정림(法正林) 사상(思想)이 점차 정착되었다. 전후기(戰後期)에는 이전의 합경종계(合耕種系)의 시업(施業)으로부터 기업적(企業的) 경영(經營)이 전개되었다. 고도성장기(高度成長期)에는 예상성장량(豫想成長量)의 벌채(伐採)와 대면적(大面積) 개벌작업(皆伐作業)에 의해 약탈적(掠奪的) 시업(施業)이 추구됨에 따라, 본래의 시업법(施業法) 및 법정림사상(法正林思想)은 부정되었고, 그 결과 삼림(森林)의 황폐(荒廢)를 초래하였다. 저성장기(低成長期)에는 감량경영(減量經營)에 의한 방치적(放置的) 시업(施業)과 불황(不況)의 심화(深化)에 의해, 삼림자원(森林資源)의 보속생산을 곤란하게 하였다. 그러므로, 금후의 국유림(國有林) 시업(施業)은 지력(地力)을 유지(維持)하여 삼림자원(森林資源)의 재생산과 환경(環境)의 보전(保全)을 동시에 실현 할 수 있는 시업법(施業法)을 확립(確立)시켜 나가야 한다. 벌출(伐出)과 경신(更新)의 통일을 기하고, 입지조건(立地條件)에 최적(最適)한 작업법(作業法) 및 수종규정법(收種規整法)의 채택 등, 제반 조건의 종합적 고려를 통한 집약적(集約的) 시업체계(施業體系)의 확립(確立)이 필요하다. 또한, 삼림자해(森林資海)의 기능적(機能的) 특성상, 삼림(森林)에 대한 보다 적극적인 투자(投資)의 확대(擴大)가 이루어져야 한다.

Logging equipment and method have a major influence on harvesting productivity and cost. This study investigated the productivity and operational costs of tree-length cable yarding system using HAM300, a domestically developed tower yarder. We tested HAM300 for thinning operation in Pinus densiflora stands at Gangreung, Gangwon-do on April, 2014. To assess the productivity we conducted time study for each stage of the operation. When the average time/cycle was examined for each stage of the operation, the longest was for yarding (241 sec), followed by delimbing (237 sec), felling (153 sec), and processing (103 sec). Furthermore, productivity for felling was $8.6m^3/hr$, followed by delimbing ($5.1m^3/hr$), yarding ($3.5m^3/hr$), and processing ($8.1m^3/hr$). The total cost for the tree-length logging system was $58,446won/m^3$, of which the majority was incurred by the yarding cost at $46,217won/m^3$ (79.3%), whereas the lowest cost was for felling at $2,359won/m^3$ (4.1%). We suggest that it is necessary to foster specialized operators and provide training in operating the tower yarder thereby implementing efficient harvesting system resulting from low-cost yarding.

Biodiversity, referring to the variety and abundance of species, their genetic composition, and the communities, ecosystem, and landscapes, is essential to maintain healthy and productive forests, and to provide useful hedge against the future uncertainties in conditions of the environment and natural resources. To realize the long-term sustainability for forest production of goods and services is dependent upon maintaining and enhancing the biodiversity in the forest ecosystem. Because we can not always recognized which portion of biodiversity is essential to maintain the stability and sustainability of the natural system, conserving biodiversity is even unconditionally important. Even though the activities of forest resource management may have a variety of negative impacts on biodiversity by modification of the natural ecosystem into economically effective artificial ecosystem, forest professionals have been developing intelligent scheme to coexist management and conservation. However, conservation of biodiversity must be a complex problem encircled by ecological, economical, and social considerations. There seems to be no such a simple and easy solution. Strategies for ecologically deliberated forest resource management, which could play an important role to conserve biodiversity, were discussed.

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.

There are 3 kinds of forest managements: One of them is forest utilization management which collects abundant forest resources by felling the trees: the second of them is scientific forest management which cultivates forest resources; and the last one is emergency aid forest management, needed by the forest resources davastation, for the surposes of soil conservation and preventing the indirect damages. During the 36 years of Japanese occupation, they pillaged 600 to 800 million cubic meters of the forest resources, in the condition of the colonial system. After the emancipation from the Japanese occupation, the national soil conservation work has been practiced for 18 years without correcting the Japanese forest management (which means felling system); therefore the essential in the forest, conservation works is to get rid of imitating the Japanese pillage management so as to turn the direction of the forestry policy to the emergency aid management which means forest investment.

After Forest Service formed a forest welfare service system by life cycle in 2008, they established a variety of policy for promoting welfare of the people. In Forest welfare service plan(2013~2017) which recently the forest service department established to along with government's welfare policy, they introduce forest welfare service voucher linked to National welfare system to provide forest welfare actively to disadvantaged citizen. The purpose of this study is to setup a direction of forest voucher system, and to make strategies of forest welfare service voucher by research existing voucher system of government. A study conducts a qualitative research by use grounded theory without a quantitative research, because there is not a lot of similar cases with forest welfare service voucher. The subject of this study is experts of National Park Authority 's voucher management, forest service's Nature recreation management and relevant researcher institution. The research is conducted by interviewing the subject and by using grounded theory analysis. After processing an opening coding, categorization of opening coding, and axis coding, induce a direction of the forest welfare service voucher system.

A sensor system has been developed that uses an ultrasonic sensor to detect the downhill slope on the side of a forest road and prevents a vehicle-type forest machine from rolling down a mountainside. A specular reflection of ultrasonic wave might cause severe issues in measuring distances to targets. By investigating the installation angle of the sensor to minimize the negative effects of specular reflection, the installation angle of lateral monitoring ultrasonic sensor could be determined based on the width of road shoulder. Obstacles such as small rocks or piece of log in a forest road may cause the forest machine to be overturned while the machine riding over due to excessive its posture change. It was determined that the laser sensor could be a part of a sensor system capable of specifying the location and size of small obstacles. Not only this sensor system including ultrasonic and laser sensors can issue a warning of dangerous sections to drivers in forest forwarders currently in use, but also it can be used as a driving safety sensor in autonomous forest machine or remote-control forest machine in the future.

본 연구는 산주들을 대상으로 사유림 지원제도 이용 실태를 조사하여 지원제도의 현황과 문제점을 분석하여 개선방안을 제시하는데 도움이 되고자 수행하였다. 사유림 경영 지원제도의 인지도에 대해서는 독림가 57.8%, 임업후계자 47.6%인 반면 일반산주는 불과 17.6% 만이 인지하고 있는 것으로 나타났다. 지원경험도 인지도와 마찬가지로 독림가 79.2%, 임업후계자 58.6%인 반면 일반산주는 28.6%로 현저하게 낮은 비율을 보였다. 지원을 신청하기 못한 이유로는 '지원제도를 모름'에 대한 응답이 독림가, 임업후계자, 일반산주 각각 36.1%, 43.0%, 78.6%로 나타난 인지도분석 결과와 유사한 경향을 보였다. 반면 사유림 경영 지원에 대한 효과정도는 독림가와 임업후계자보다 일반산주가 높게 나타났으며, 전반적인 만족도 역시 독림가 28.5%, 임업후계자 36.8%, 일반산주 41.5%로 나타나 오히려 다소 지원횟수가 적은 일반산주에게서 경영전반에 대한 만족도가 높은 것으로 나타났다. 이에 따라 우리나라 산주의 대부분을 차지하는 일반산주의 적극적인 산림경영을 유도하기 위해서 사유림 지원제도의 인지도 개선이 필요하며, 지자체와 산림조합의 적극적인 홍보대책과 지원정책 마련이 필요할 것으로 보인다.
