The purpose of this study was to define the relationship between respondents' social economic condition and willingness to pay on forest landscape. From the result of analyzing the difference of willingness to pay amount with considering social economic condition by using statistical technique, it was found that willingness to pay amount was highest when people are able to access forests landscape. In addition, it was found that women's willingness to pay amount was higher than that of men and the person such as laborer and public employee, who could spare enough time, had the intention to pay higher amount, than the person such as specialist and self-employed person, who spare enough money. For age, it was found that the retired people in their sixties showed low willingness to pay amount on forest scenery. For income per household, it was interesting that although willingness to pay amount increased as income increased, it was rather low in high income class, whose income was more than KRW 10 million.

This study investigated the effects of various planting models on the joint cultivation of eggplant (Solanum melongena) and marigold (Tagetes erecta)to enhance sustainable rooftop urban farming. Rooftop agriculture is increasingly valued to boost the food supply and benefit the environment. Integrating such practices into urban planning is viewed as a way to sustainably manage resources and improve the food-energy-water cycle in cities. The experiment was conducted on a rooftop in Chungju, South Korea from May to August. Four different planting setups were used: central eggplant with peripheral marigold (SET), eggplant with a protective net (SIC), central marigold with peripheral eggplant (TES), and control with only eggplant (CON S). These models tested the effects of companion planting versus monoculture using a lightweight soil mix ideal for rooftops made from cocopeat and perlite and enriched with organic fertilizer. Measurements focused on soil conditions and plant health and assessed soil temperature, moisture, conductivity, plant height, width, and leaf size. The results indicated that the SET modelyielded the best growth. This setup benefited from marigold pest control properties and its ability to improve soil conditions by enhancing moisture and nutrient levels and aiding eggplant growth. These findings underscore the potential of mixed planting on rooftops and suggest that such approaches can be effectively incorporated into urban agriculture to boost yield and environmental sustainability. This study supports the idea that diverse planting methods can significantly affect plant growth and promote urban greening and food security.

This study was conducted to analyze the type and priority order of forest functions that is suitable in assessing a private forest. A questionnaire survey of experts group and forest officers from the city and county office was conducted and the appropriateness of forest functions type and priority order of function were assessed. Based on the survey conducted, they mostly agreed that it is necessary to change the name of forest functions and integrate the forest functions. Four classifications of forest functions were presented: resources rotation, water yield, living environment, and forest conservation. As the variety of organizations and geographical areas determine which forest functions are the priority, it is necessary to determine which function will become the priority order according to geographical areas, instead of simply dividing the forest functions into national and publicly owned forest when assessing the forest functions of private forests across the nation.

The purpose of this research is to seek political implications for management and activation of National Forest Complex Management(NFCM). Survey method was utilized for workers as respondents to measure importance and performance of NFCM. As a result, it turned out that the respondents' performance was very high. In addition, out of 14 items, two items -1) activation of e-commerce and direct business transaction, 2) production and sales marketing information, which intensive management strategy, were derived from results. Also, 6 items were derived for on-going maintenance, 3 items were derived for low priority order, and other 4 items were derived for discouragement against excessive efforts. This research may contribute to providing fundamental sources that can be utilized for promoting direction establishment and system improvement of NFCM.
