A model is developed for estimating optimal cultivation areas for apples to maximize the total profit of apple farming by region, focusing on Gyeongsangbuk-do, Chungchungbuk-do, Gyeongsangnam-do, and Jeonllabuk-do in Korea. Comparing the current cultivation areas to the optimal areas according to the model estimation during the period 1999 - 2019, the former has exceeded the latter since 2015 in all regions except for Jeonllabuk-do. This result stems from a lack of the regulation of production quantity among apple producers' regional organizations. Accordingly, the decreasing rate of the market price was greater than the increasing rate of the production quantity, and the total profit of apple farming has fallen in conjunction with increasing agricultural wage rates. Therefore, in order to reverse the current decreasing trend in the profits of apple farming, it is necessary to regulate nationwide apple cultivation areas through regional producers' associations. Ex-ante forecasting for 2019 posits the following regional optimal cultivation areas for maximizing the total income from apple farming. The Gyeongbuk apple producers' association needs to reduce its current cultivation area by 1,089 ha and to maintain 18,373 ha. In the Chungbuk region, current cultivated area should be reduced by 1,027 ha to maintain 2,722 ha, and in the Gyeongnam region, the current cultivated area should be reduced by 582 ha to maintain 2,730 ha. In contrast, the Jeonbuk region needs to increase its current cultivation area by 174 ha and to maintain at a level of 2,872 ha.

Background: Dental hygienists undergo 3 or 4 years of college education, and dental hygienist education must receive continuous feedback through evaluation. The purpose of this study was to compare the educational performance of students from the Department of Dental Hygiene in 2018 with those from other departments in the healthcare field. Methods: We used data from the National Assessment of Student Engagement in Learning, conducted by the Korean Educational Development Institute in 2018. The survey data of 55 dental hygiene students and 60 healthcare students at K University were provided after excluding all identifying information. An independent t-test was used for comparisons between the Department of Dental Hygiene and other healthcare departments. Results: Regarding class-related activities, dental hygiene students were passive in presentations, discussions, and projects and had significantly lower grades in cooperative learning and challenging learning. Regarding extra-class activities, dental hygiene students had significantly lower global learning and external experiences, domestic experiences, club activities, and interactions with professors. Regarding learning outcomes, students had significantly lower grades in writing, speaking, critical and analytical thinking, data evaluation, understanding of data meaning, problem-solving ability, goal setting and execution, core content extraction, human and material resource utilization, creative convergence thinking, statistical understanding and analysis, information technology use, collaboration, sense of community, stress management, time management, and foreign language proficiency. Conclusions: Dental hygiene education requires innovation in educational methods and efforts of instructors to improve poor learning activities and outcomes.

It is generally accepted that cultural capital is constructed through cultural environments that facilitate the cultural activities of individuals. Although public libraries foster the cultural environment and support various cultural activities, there is controversy about whether public libraries still affect the formation of cultural capital in the current evolved cultural environment. This research empirically verified the roles of public libraries in the formation of cultural capital by conducting a survey targeting public library users. As a result, public libraries as cultural institutions play an important role in providing opportunities to access and utilize cultural resources and to experience various cultural activities, which are connected to the formation of different types of cultural capital. In addition, public libraries function to close the cultural divide and social disparities by providing equal opportunities to construct cultural capital for community members.

Korea aimed to increase water use efficiency by implementing integrated management according to the water management unification policy. Therefore, the necessity of establishing and operating governance is expanding to ensure the sustainability of agricultural water. In this study aims to evaluate the importance of agricultural water governance components and provide essential data for the participation of stakeholders in the efficient use of agricultural water in Korea. For this study, a total of 19 respondents to the ANP survey for this study were composed of experts in agricultural water and governance in Korea. As a result, the ranking for the main components was in the order of law, policy, and systems(0.222), core subjects(0.191), information sharing and communication(0.180), budget support(0.178), mutual learning(0.124), and external experts(0.105). The most important components for the operation of agricultural water governance are laws, policies, and systems. Since Korea's agricultural water management is a public management system, national standards are considered the first priority. This study, which is the purpose of the agricultural water governance model, evaluated the importance of the constituent components for participating in demand management with a sense of responsibility. Moreover, if agricultural water governance is expanded nationwide by reflecting agricultural and water resource policies in the future, it is believed that positive effects can be achieved in increasing utilization efficiency and securing sustainability through agricultural water saving.

Drawing on an open system approach to understanding schools as organizations, this study examined whether challenges experienced by teachers in immigrant neighborhoods are mitigated to the extent in which schools effectively collaborate with parents and other agents in the neighborhoods. Data were gathered from a total of 328 teachers in 32 elementary and middle schools located within areas characterized by high levels of immigrant residential concentration in Seoul and Gyeonggi. The data showed that challenges experienced by teachers were significantly lessened in schools that had organic ties with agents in the external environments. This finding sheds new light on the importance of understanding schools as open-system organizations whose successful performance largely depends on factors external to classrooms. It appears that boundary spanning and bridging strategies may be utilized by school leaders to improve teachers' task performance at schools in areas of immigrant concentration.

This study aims to identify the core competencies required in the field of Library and Information Science (LIS) and to propose curriculum design strategies based on these competencies. The expansion and increasing demand for librarian certification pathways have led to the weakening of professional expertise and growing uncertainty in the job market. In response, this research collected competency-related data from the websites of 16 four-year LIS programs at universities across the country and qualitative data through in-depth interviews with professors from related academic fields and public library managers. The analysis identified five core competencies in LIS: information management and processing, information technology and data utilization, library management and collaboration, user services and communication, and cultural and community understanding. Based on these competencies, the study suggests curriculum design strategies across institutional, practical, and educational dimensions. This research serves as a foundational resource for improving LIS curricula and certification systems and is expected to facilitate collaborative discussions between educators and practitioners in the field.

This study aims to analyze the effect of local government capacities on the rise of social start-ups including social enterprises, cooperatives, and community business. Social economy is considered as an alternative model for welfare, employment and local economy. Until now, existing literature on social economy has been limited to individual organizations or specific regions, and no empirical analysis has been conducted at the nationwide level. In this study, we examine how to explain the variation of the number of social economic entities across the country. As a result, the following factors prove to be important in the rise of social economy in a local area. First, the number of professional civil servants dedicated to the task is the important factor, rather than to establish a team-based system. Second, local governments' own welfare spending is the crucial resource for the social economy. Finally, the integrated network activity of the social economic organization positively influences the growth of the social economic entities. With the finding, we confirm the crucial role of local governments in the growth of social economy and finally draw some policy implications.

Purpose: Periodontal disease is a chronic condition caused by microbial infection and mediated by the host's immune response. Phytotherapy is a therapeutic approach that utilizes a renewable resource capable of supplying less expensive medicines for the world's growing population. This review aimed to present clinical evidence on the use of complementary medicinal herbs in the treatment of periodontal diseases. Methods: Different databases were searched using the terms "herbal" and "periodontitis." All included studies were examined with a focus on herbal indications, type, and prescription length. Dentists' therapeutic and prophylactic herbal prescribing habits were also assessed. Results: Various herbs such as turmeric, neem, aloe-vera, pomegranate, catechu, tulsi, cloves, lemon grass, green tea, tea tree oil, peppermint, garlic, pineapple, oak bark, babul, bakul, sage, coriander, moringa, amla, guava, and grape seed extract have been used in the treatment of periodontitis. These herbs have been reported to exhibit a range of therapeutic effects, including anti-inflammatory, antiplaque, antihalitosis, antiresorptive, antioxidant, antibacterial, antifungal, antiviral, and antimicrobial properties. These components can be utilized in various forms such as mouth rinse, gel, oil, toothpaste, aqueous extract, mouthwash, or tooth powder. Conclusions: Several readily available herbal formulations are now available on the market and have been shown to be effective as supplemental periodontal phytotherapy. However, these should be used under the supervision of a dental professional to ensure optimal benefits and effectiveness. Therefore, it is necessary to improve the understanding of suggested herbal prescription practices among dental professionals.

Objectives: This study was to identify socioeconomic factors and health-related behaviors influencing on HRQOL(health-related quality of life) for the older adults in rural area. Methods: 483 subjects aged over 65 years responded a direct interview, which covered HRQOL, BMI, socioeconomic characteristics, and health-related behaviors including smoking, drinking, and exercise. Results: Overall, the mean number of healthy days were 15.1 days and not significantly different by sex. Men didn't show a significant difference in HRQOL by age group. But women reported lower levels of healthy days and higher levels of activity limitation and physical unhealthy days with increasing age. Results from ANCOVA showed HRQOL to be significantly associated with education, job, and family type. Men presented no significant difference in HRQOL by health-related behaviors, but women who have been drinking, or have less number of chronic diseases reported higher mean healthy days and lower activity limitation days, physical unhealthy days, and mental unhealthy days. Older adults who reported good to excellent self-rated health were higher healthy days and lower activity limitation, physical unhealthy days, and mental unhealthy days than those who reported fair to poor health status. Conclusions: The HRQOL for the older adults in rural area was related to socioeconomic characteristics, health-related behaviors and self-rated health status. A better understanding of factors related to HRQOL would help to improve the older adults' quality of life.
