This study was conducted in the spring of 2005 through personal interviews to examine the opinions of forest products manufacturers and consumers about the perspective of forest certification in South Korea and to characterize those consumers who expect the activation of a forest certification system in South Korea. Study results indicated that consumers showed more positive aspect for the activation of forest certification than forest products manufacturers. Respondents who had a negative view for establishing a forest certification system in South Korea pointed out a lack of customers' demand for certified wood products as the most important reason. Results also showed that, even when a forest certification system would be introduced as a possible policy for helping to attain sustainable forest management, it would take at least 5 to 10 years to establish a forest certification system in South Korea. To facilitate the establishment of the system, many respondents suggested that an increased public awareness of forest certification systems was the most required precedent condition, and government for manufacturers and forest management association for consumers had to certify forest management practices as a competent organization. A profile of consumers who expected the activation of a forest certification system would describe in relative terms as the highly educated female who interviewed in the city of Seoul and of the 20 age bracket. Although there were an increased public awareness and positive prospective of forest certification by consumers and forest products manufacturers, it is required to arouse much more interest of consumers about the system.

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.

Pinus densiflora and Larix kaempferi forests not only extended the plantation management area but also cultivated to the sustainable wood supply chain during the last 5-years. These prescriptions are primarily done by manual operation activities, particularly in young tree tending. Two types of tending activities, brashing by brush cutter(BB) and pruning by pruning shear and saw(PP), were selected for the investigate of musculoskeletal disorders' level and postural risks using Ovako Working Posture Analysis System (OWAS). The postural risk indexes (BB and PP) ranged from 115 to 125 and 102 to 105, respectively. There is no significant difference between the species. The young tree tending operations had low postural risks. The results may be used as basic data to develop technical guideline for safe young trees.
