  • Purpose: Climate change is greatly affecting the frequency and intensity of fires around the world. The main effects of climate change on fires are rising temperatures, dry seasons and extreme droughts, changes in precipitation, increased strong winds, extended fire danger periods, and changes in natural ecosystems. Several factors due to climate change are increasing the risk of large-scale fires, such as wildfires. Research design, data and methodology: Rising temperatures caused by climate change will make forests and grasslands drier, make it easier for wildfires to occur in drier environments and spread quickly to wider areas, and the generated wildfires will release large amounts of greenhouse gases into the atmosphere, such as carbon dioxide (CO2), and the released greenhouse gases will strengthen the global greenhouse effect, further raising the temperature. As temperatures rise, the risk of wildfires increases in drier environments, and this process is repeated, leading to a vicious cycle of intensifying climate change as more fires occur and more greenhouse gases are released. Results: In conclusion, climate change is increasing the risk of fire occurrence and this phenomenon is expected to become more frequent and severe in the future. Conclusions: In order to cope with the increasing fire risk caused by climate change, fire prevention and management. Fire detection and response systems need to be strengthened, supportive policies and international cooperation are needed to restore ecosystems, and these measures, along with fire prevention, management and countermeasures, should take into account long-term climate change and adaptation as well as short-term responses.

  • This study aims to contribute to resolving the critical issue of weed management in newly established alfalfa fields, study has been conducted on effective herbicide use. The study evaluated the impact of various domestically available foliar herbicides on alfalfa phytotoxicity, weed control, yield, and nutritive value. The experiment was designed in a randomized complete block design with four treatments. Alfalfa 'SW 5615' seeded in the spring of 2024 on a 1 ha field (March 18), with herbicide treatments including fluazifop-P-butyl (FPB), bentazone (BEN), and a mixture of these herbicides (MIX). Herbicide efficacy, alfalfa yield, and nutritive value were assessed 30 days post-application. Results indicated that the MIX treatment achieved superior weed control comparable to hand weeding (HW), although it exhibited higher phytotoxicity, requiring extended recovery periods. While MIX led to lower overall yield, it enhanced alfalfa purity, resulting in higher crude protein (CP) content and relative feed value (RFV) compared to other treatments. The study concludes that despite the potential for increased phytotoxicity, mixed herbicide treatments could offer a strategic advantage in enhancing the quality of alfalfa feed through effective weed management, thereby improving CP and RFV, critical factors for the nutritional value of alfalfa. These findings provide valuable insights for optimizing weed management practices in alfalfa cultivation, suggesting that mixed herbicide application, although associated with increased phytotoxicity on the plants, could improve the overall feed quality by reducing weed competition.

  • Although invasive alien species (IAS) have a negative impact on native ecosystems and reduce ecosystem services and productivity, the understanding of IAS at the population level is still lacking. Coreopsis lanceolata, a perennial plant native to North America, is expanding its invasive range, but there is limited research on the invasion risk of this species, and measures to control its spread are inadequate. Therefore, we collected findings from selected studies on C. lanceolata, examining its morphological and growth characteristics, reproductive traits, and invasion strategies, sourced from scientific databases using its scientific name as the keyword. Researchers have conducted extensive research on C. lanceolata, primarily focusing on the extraction of chemical compounds for anticancer and antioxidant effects and numerous studies on seed germination conditions in the field of ecology. Coreopsis lanceolata has a negative impact on plant ecosystems in Australia and Japan, and its high invasiveness is associated with high seed production, high seed viability and longevity, rapid reproduction through rhizomes, high surface coverage, and long flowering periods. Few studies have examined the invasive potential of C. lanceolate and management techniques to stop its spread, despite worries about the detrimental effects of invasion on plant ecosystems. Therefore, additional research on the invasion risk and management of C. lanceolata is necessary. This review offers a thorough analysis of C. lanceolata, serving as a scientific foundation for devising future ecosystem management strategies.

  • Buddhism was introduced in the Korea Peninsula 1600 years ago, and now there are over 10 million believers in Korea. The systematic Management of Temple Records has a spiritual and cultural value in a rapidly changing modern society. This study proposes a better management system of Buddhist temple records for the Jogye Order of Korean Buddhism. this system Not only supports transparency of religious affairs, but presents a way for a more effective management. in this study, I conducted a study on the national legislation for the preservation of buddhist temples and the local rules of religious affairs from the Jogye Order. Through this, I analyzed the problems of Buddhist records management. in the long term, to improve these problems, I purpose the establishment of temple archives be maintained by parish head offices. This study presents a retention schedule for this systematic establishment system. I present charts for the standard Buddhist records management that manage the total process systematically from the production of records to its discard. Also I present a general plan to prevent random defamation of Buddhist temple documents and impose a duty for preservation. I intend for this plan to be subject to discussion and tailored to the particular needs of temple reads. In creating these charts standard of Buddhist temple records management, I analyzed operating examples of foreign religious institutions and examined their retention periods. I also examined the retention periods and classification system from the Jogye Order. Then I presented ways for this management system to operate through computer programs. There is a need to establish a large scale management system to arrange the records of buddhist documents. We must enforce the duty of conserving records through the proposed management system. We need the system to manage even the local parish temple records through the proposed management system and the operation of the proposed archive system. This study presents research to from the basic of the preservation and the passing of traditional records to future generations. I also discovered the historical cultural and social value that these records contain. Systematically confirmed Buddhist temple records management will pave the way that these tangible and intangible cultural records handed down from history can be the cultural heritages. establishing a temple records management system will pave the way for these cultural records to be handed down to future generations as cultural heritages.

  • The population of small yellow croaker, Larimichthys polyactis, in the Yellow and East China Seas has decreased significantly since the mid 1970s. Several management measures have been introduced to conserve it, but population size remains low. To rebuild this population, it is now necessary to consider more effective management methods based on the stock assessment. To determine long-term population changes, fishery and biological data collected over 34 years (1969-2002) were analysed. Yearly fish length compositions were analysed for the time periods 1968 through 1970, 1978 through 1982, and 1993 through 2002; and catch data was available from 1969 to 2002. Annual population sizes were calculated based on length composition, the relationship between total length and body weight, and total landings. Analyses showed that since the 1970s, average size of harvested fish decreased; the proportion of less mature fish (smaller than the 50% maturity length, 19cm) in catches has increased and the estimated biomass has decreased significantly. Consequently, the main management recommendation is that juvenile fish need to be better protected to allow the rebuilding of resources to a more sustainable population level. This will require fish size limit, permissible mesh size, and closed area and season regulations.

  • Purpose: The purpose of this study was to develop and apply a motivation-strengthening obesity management program for obese subjects with visual impairment and evaluate its effects. Methods: The program development and evaluation periods were from March to August 2018. The study design was an experimental study of non-equality, control repeat design. 25 subjects in the experimental group participated in the 12-week obesity management program and the 26 people in the control group did not. Results: The motivation-strengthening obesity management program included stretching exercises for 30 minutes in the morning five times a week. In addition, counseling, education, and group discussions were continued once a week for motivational strengthening. Special custom exercises for blind patients were also completed once a week simultaneously. Both of these activities were continued for 50 minutes a week for a total of 12 weeks. Measurements were recorded periodically to identify the sustained effects of the program. The obese subjects with visual impairment improved their knowledge of obesity, perceived disability, self-efficacy of exercise, and quality of life related to obesity through the motivational obesity management program. Waist circumference, systolic blood pressure, diastolic blood pressure, and fasting blood sugar were also improved in obese subjects. Conclusion: The study findings indicate that this program could be an active intervention for the control of weight gain in participants with visual impairment. Therefore, the motivation-strengthening program based on the ADDIE (Analysis, Design, Development, Implementation& Evaluation) model could be an effective strategy for better health outcomes of obese subjects with visual impairment.
