Background: Breast cancer is the commonest cancer among Sri Lankan females, accounting for 26% of the cancer incidence in women. Early detection of breast cancer is conducted by public health midwives (PHMs) in the Well Woman Clinics. The aim of the present study was to determine the effectiveness of an educational intervention on improving knowledge, attitudes and practices (KAP) on breast cancer screening among PHMs in the district of Gampaha. Materials and Methods: Two Medical Officer of Health (MOH) areas in Gampaha district were selected using random sampling as intervention (IG) and control (CG) groups. All the PHMs in the two MOH areas participated in the study, with totals of 38 in IG and 47 in CG. They were exposed to an educational intervention with the objective of using them to subsequently conduct the same among 35-59 year women in the community. Following the intervention, post-intervention assessments were conducted at one month and six months to assess the effectiveness of the intervention. Results: The overall median scores for KAP among PHMs respectively were as follows. Pre-intervention: IG:58%(IQR: 53-69%), 90%(IQR: 70-100%) and 62%(IQR: 57-70%). CG: 64%(IQR: 56-69%), 90%(IQR: 70-90%) and 62%( IQR: 50-77%). Post-intervention: one month, IG:96%(IQR: 93-96%), 100%(IQR: 100-100%), and 85%(IQR: 81-89%). CG:67%(IQR: 60- 73%), 90%(IQR: 80-100%) and 65%(IQR: 50-73%). Post-intervention: six months, IG: 93% (IQR: 91-93%), 100%(IQR: 90-100%), and 81%(IQR: 77-89%). CG: 67%(IQR: 58- 71%), 90%(IQR: 90-100%), and 62%( IQR: 58-73%). All the above post-intervention scores of PHMs in the IG were significantly higher in comparison to CG (p<0.001). Conclusions: This planned educational intervention had a significant impact on improving KAP of PHMs for early detection of breast cancer in the Gampaha district.

The impact of 1 pound of nitrous oxide ($N_2O$) on warming the atmosphere is almost 310 times that of 1 pound of carbon dioxide. Agricultural soil management is the largest source of $N_2O$ emissions, accounting for about 73% of total $N_2O$ emissions. This study was conducted to evaluate the nitrous oxide emission in the cultivation of soybean during the first year of No-tillage (NT) and Conventional-tillage (CT) practices, under the various conditions such as different kinds of fertilizers, soil temperature, and moisture level. In the experiment, we set CT and NT treatments into 4 different groups - control treatments (no fertilization), green manure treatments, chemical fertilizer treatments and organic manure treatments. In the case of chemical fertilizer treatments, $N_2O$ emission of NT treatment was 7.78 to 22.59% lower than CT treatment. In organic manure treatment, $N_2O$ emission of NT treatment was 6.62% higher than CT treatment in August. But In July and September, $N_2O$ emission of NT treatment was 9.50% 28.38% lower than CT treatment, respectively. Soil temperature was correlated with $N_2O$ emission positively. In the future, continued long-term research on influence of various environmental factors on the generation of $N_2O$ and the economic value of no-till farming is required.

Purpose : The purpose of this study was to investigate the effect of the perceived nursing work environment (NWE) on person-centered critical care nursing (PCCN) practices among nurses in intensive care units (ICUs). Methods : A cross-sectional research design was adopted for this study; participants were 126 ICU nurses working in five hospitals in B city. From December 2018 to February 2019, a survey questionnaire on NWE and PCCN were conducted. The collected data were analyzed with a multiple hierarchical regression analysis. Results : The mean score for NWE was $2.98{\pm}0.39$. Among the factors, basic work system was the highest ($3.39{\pm}0.41$), followed by leadership of the head nurse ($3.31{\pm}0.55$), interpersonal relationships ($2.77{\pm}0.62$), and institutional support ($2.58{\pm}0.52$). The mean score for PCCN was $3.52{\pm}0.46$. Among the factors, comfort was the highest ($3.77{\pm}0.62$), followed by respect ($3.55{\pm}0.56$), compassion ($3.43{\pm}0.60$), and individuality ($3.38{\pm}0.56$). The interpersonal relationship (${\beta}=.31$, p=.001) and the number of patients per shift (${\beta}=-.23$, p=.005) had a significant effect on PCCN, accounting for 25.9% of the total variance. Conclusion : These results suggest that it is necessary to enhance the relationship-oriented culture and reduce the workload of nurses in order to improve the quality of nursing care in ICUs.

The aim of this study is to analyze the current status and performance evaluation systems of faculty in Korean medical colleges and professional graduate medical schools (called medical schools). We developed a research tool based on previous studies and distributed it to 40 medical schools from July to October 2017. The response rate was 100%. We calculated the number of faculty members and analyzed the faculty evaluation systems and awareness according to national and private medical schools. As of 2017, the number of medical faculty in Korea was 11,111 (4,973 faculty were employed by their alma mater, which is 44.76% of the total), with non-medical doctor faculty accounting for 754 of the total. The medical schools reflect research achievements as most important for re-appointment and screening to promote faculty, and the area of education is secondary excepting clinical faculty of private medical schools. However, important issues in the faculty evaluation deal with the relevance of research achievement and the need for qualitative assessment. Some medical schools revised or have been revising the faculty evaluation system in areas such as minimum standards of education for promotion and separation of promotion and tenure review. Opening non-tenure track lines for faculty show positive effects such as increasing the number of positions for hire and easing the financial burdens of medical schools. Downfalls include inconsistencies between the responsibilities and actual practices of tenure not being available and the instability of faculty's status. In conclusion, medical schools need to prepare a faculty evaluation system that fits the position of faculty members and attempt to establish a reasonable compensation system.

Irrigation return flow is defined as the excess of irrigation water that is not evapotranspirated by direct surface drainage, and which returns to an aquifer. It is important to quantitatively estimate the irrigation return flow of the water cycle in an agricultural watershed. However, the previous studies on irrigation return flow rates are limitations in quantifying the return flow rate by region. Therefore, simulating irrigation return flow by accounting for various water loss rates derived from agricultural practices is necessary while the hydrologic and hydraulic modeling of cultivated canal-irrigated watersheds. In this study, the irrigation return flow rate of agricultural water, especially for the entire agricultural watershed, was estimated using the SWMM (Storm Water Management Model) module from 2010 to 2019 for the Madun reservoir located in Anseong, Gyeonggi-do. The results of SWMM simulation and water balance analysis estimated irrigation return flow rate. The estimated average annual irrigation return flow ratio during the period from 2010 to 2019 was approximately 55.3% of the annual irrigation amounts of which 35.9% was rapid return flow and 19.4% was delayed return flow. Based on these results, the hydrologic and hydraulic modeling approach can provide a valuable approach for estimating the irrigation return flow under different hydrological and water management conditions.

Latin America is a culturally, geographically, politically, and economically diverse region. Agriculture in Latin America is marked by a remarkable diversity of production systems, reflecting various agroecological zones, farm sizes, and technological levels. In the last decade, the swine industry increased by 30.6%, emerging as a great contributor to food security and economic development in Latin America. Brazil and Mexico dominate the pig production landscape, together accounting for 70% of sow inventory in the region. The swine industry in Latin America is predominantly comprised of small and medium-sized farms, however, in the past 30 years, the number of pig producers in Brazil dropped by 78%, whereas pork production increased by 326%. Similar to the global pork industry, the growing demand for pork, driven by population growth and changing dietary habits, presents an opportunity for the industry with an expected growth of 16% over the next decade. The export prospects are promising, however subject to potential disruptions from global market conditions and shifts in trade policies. Among the challenges faced by the swine industry, disease outbreaks, particularly African Swine Fever (ASF), present significant threats, necessitating enhanced biosecurity and surveillance systems. In 2023, ASF was reported to the Dominican Republic and Haiti, Porcine Reproductive and Respiratory Syndrome (PRRS) in Mexico, Costa Rica, the Dominican Republic, Colombia, and Venezuela, and Porcine Epidemic Diarrhea (PED) in Mexico, Peru, the Dominican Republic, Colombia, and Ecuador. Additionally, feed costs, supply chain disruptions, and energy expenses have affected mainly the smaller and less efficient producers. The swine industry is also transitioning towards more sustainable and environmentally friendly practices, including efficient feed usage, and precision farming. Ensuring long-term success in the swine industry in Latin America requires a holistic approach that prioritizes sustainability, animal welfare, and consumer preferences, ultimately positioning the industry to thrive in the evolving global market.
