The application discloses a terpene polymerization catalyst resistant to papermaking black liquor impurity poisoning and a preparation method and application thereof, and belongs to the field of forest product chemical industry and catalysis technology. The catalyst comprises: a porous carbon carrier prepared from recovered lignin in papermaking black liquor by adjusting the pH of the lignin to 5.5-6.5 through acid, impregnating and activating the lignin in a phosphoric acid solution, and carbonizing the lignin at 350-450 DEG C for 4-6 h; an active component loaded on the porous carbon carrier; and an anti-poisoning modification layer coated on the surface of the catalyst, wherein the anti-poisoning modification layer is APTES. The application further provides a preparation method of the catalyst, a method for preparing terpene resin by using the catalyst, and application of the terpene resin in pressure-sensitive adhesive. The catalyst has excellent anti-poisoning capacity for lignin sulfonate and acetic acid complex impurities in recovered pinene in papermaking black liquor, and can stably polymerize in a wide range of mass ratios of alpha-pinene to beta-pinene of 60:40 to 90:10.

The present invention relates to an area-linked forest product cultivation game system based on ecosystem services of mountain villages. The present invention allows a user to experience the enjoyment of a mountain village life through a virtual forest product cultivation game that reflects the ecosystem of a mountain village area, and a virtual activity in the game to be linked to the consumption of reality through a reward system linked to a store in an actual mountain village area, thereby promoting the consumption of specialties from the mountain village area and contributing to the activation of local economy. The present invention is a technology developed through Academic Research Infrastructure Establishment Program for Science and Engineering (2340002809 / 2021R1I1A3044195), "Development and application of a Korean-style sustainable forest ecosystem service management model" on March 01, 2024 to February 28, 2025 supported by the National Research Foundation of Korea grant funded by the Ministry of Education of Korea.

The present invention relates to a system and method for introducing sweetness including that from stevia into food containing forest and agricultural products. More specifically, the present invention relates to a system and a method for increasing the sugar content or sweetness of forest and agricultural products within a short time after harvesting the forest and agricultural products. To this end, the system is equipped with a chamber that is a device used for inputting and processing an enzyme-treated stevia liquid material after harvesting the forest and agricultural products (forest products, agricultural products); and a related device for checking and maintaining an appropriate state of the chamber so that the enzyme-treated stevia liquid material is input as much as a predetermined sugar content.
