“…However, there were still debates on whether the benefits of CO 2 fertilizer effects on GPP and NPP were offset by the negative influences of increased temperatures and changes in precipitation, such as heat stress and drought [45][46][47]. Elevated temperature reduced soil moisture and triggered stomatal closure due to increases in transpiration, leading to negative impacts on the growth of Pinus densiflora, which could be compensated by elevated CO 2 , as shown in free air CO 2 enrichment (FACE) studies [16,[48][49][50]. In this study, to explore interactions between climate change and forests, we studied separately and in combination the impacts of climate change on the growth of Pinus densiflora for the case of a research forest in South Korea.…”

“…This tree has been restored under a forest development plan since the 1970s [12,13]. Previous studies found that under representative concentration pathway (RCP) 8.5 scenarios, the Pinus densiflora growth rate would decrease by the 2050 s in South Korea [14][15][16][17]. However, mechanistic explanations were limited in these studies, since they were primarily based on statistical trend analysis using age, density, stand growth, and topography wetness index.…”

We examined the influence of climate change on the dynamics of Pinus densiflora, the most dominant tree species in South Korea, to explore its potential for climate change mitigation. We considered changes in precipitation, temperature, and CO2 under four representative concentration pathway (RCP) scenarios separately and in combination to evaluate the responses of Pinus densiflora to climate change. A well-tested ecohydrological and biogeochemical model, ecosys, was used to study the Gwangneung Experimental Forest in South Korea. Results showed that the positive effects of CO2 fertilizer on gross primary productivity (GPP) and net primary productivity (NPP) outweighed the negative effects caused by changes in precipitation and temperature. In particular, NPP improvements of 3.79%, 13.44%, 18.26%, and 28.91% were modeled under RCP values of 2.6, 4.5, 6.5, and 8.5, respectively, compared to the baseline. We found that nitrogen leaching and N2O flux reduced as climate change become severe due to increases in nutrient uptake, leading to reduced soil nitrogen losses. Although evapotranspiration increased as the intensity of climate change increased, reductions in the stomatal opening improved the water use efficiency of Pinus densiflora. These results indicated that Pinus densiflora could serve as an environmentally friendly option to minimize climate change consequences.

The main objective of this study was to develop the estimation models for air temperature (Ta), soil temperature (Ts) at 15 cm depth and the difference (dT = Ta -Ts) in Sandy Loam under Napa Cabbage cultivation. The verification process was based on the error analysis criteria. Results indicated a positive correlation between Ta and Ts, with higher Ta corresponding to higher Ts. The estimation models for Ta and Ts according to Julian date were developed as a log functions (log model for Ta, LMTa; log model for Ts, LMTs) judged ｢Fit｣ and ｢Fit well｣, respectively. The linear regressions for Ts and dT as the LRMTs (linear regression model for Ts) and LRMdT (linear regression model for dT) judged ｢Fit｣ and ｢Unfit｣, respectively. Furthermore, an analysis revealed that higher Ta, combined with lower water content, led to an increase in dT. A double regression model for dT, considering both Ta and Qv (double regression model for dT, DRMdT), was found to be a good fit for the dataset. In summary, this study successfully developed estimation models for Ta, Ts, and dT, employing both logarithmic and linear regression approaches. The models were rigorously evaluated using error analysis criteria, providing valuable insights into temperature dynamics in Sandy Loam during Napa Cabbage cultivation.

Becoming a city Buddhist among the young generation in Seoul

The quest for spirituality among young urban dwellers represents a novel and highly distinctive form of social reproduction in contemporary South Korea. As young people are forced by a hyper-competitive work environment, fragmenting family, and high youth unemployment, they strive to overcome the attendant feelings of stress and anxiety, turning to the anti-materialist values of Buddhism. Within this context, the emergence of Mahayana Buddhism’s ‘engaged Buddhism’ – as manifested in Jungto Society – provides an interesting case study to examine the ways in which the culture of healing is being popularized among the young city dwellers. Of particular appeal to this generation is Jungto Society’s combination of individualistic practice with social action, which also differentiates it from other Buddhist organizations. Based on participant observation and in-depth interviews with young city dwellers who engage in Buddhist meditation and practices, this article aims to analyze how a young urban population strives to reconcile the knowledge and management of one’s heart, promoted by Buddhist religion, with the neoliberal ethos of self-improvement. This article argues that the fundamental Buddhist concepts generate a certain form of self-reflection among their practitioners that expands both their religious and civic minds.
