The objective of this study was to investigate the effect of maize source and complex enzymes containing amylase, xylanase and protease on performance and nutrient utilization of broilers. The experiment was a $4{\times}3$ factorial design with diets containing four source maize samples (M1, M2, M3, and M4) and without or with two kinds of complex enzyme A (Axtra XAP) and B (Avizyme 1502). Nine hundred and sixty day old Arbor Acres broiler chicks were used in the trial (12 treatments with 8 replicate pens of 10 chicks). Birds fed M1 diet had better body weight gain (BWG) and lower feed/gain ratio compared with those fed M3 diet and M4 diet (p<0.05). Apparent ileal crude protein digestibility coefficient of M2 was higher than that of M3 (p<0.05). Apparent metabolisable energy (AME) and nitrogen corrected AME (AMEn) of M1 were significant higher than those of M4 (p<0.05). Supplementation of the basal diets with enzyme A or B improved the BWG by 8.6% (p<0.05) and 4.1% (p>0.05), respectively. The fresh feces output was significantly decreased by the addition of enzyme B (p<0.05). Maize source affects the nutrients digestibility and performance of broilers, and a combination of amylase, xylanase and protease is effective in improving the growth profiles of broilers fed maize-soybean-rapeseed-cotton mixed diets.

BACKGROUND: Soil bacteria play important roles in organic matter decomposition and nutrient cycling during the non-growing season. The purpose of this study was to investigate the effects of soil management and chemical properties on the utilization of carbon sources by soil bacteria in paddy fields. METHODS AND RESULTS: The Biolog EcoPlate was used for analyzing community-level carbon substrate utilization profiles of soil bacteria. Soils were collected from the following three types of areas: plain, interface and mountain areas, which were tested to investigate the topology effect. The results of canonical correspondence analysis and Kendall rank correlation analysis showed that soil C/N ratio and NH₄⁺ influenced utilization of carbon sources by bacteria. The utilization of carbohydrates and complex carbon sources were positively correlated with NH₄⁺ concentration. Cultivated paddy fields were compared with adjacent abandoned fields to investigate the impact of cultivation cessation. The level of utilization of putrescine was lower in abandoned fields than in cultivated fields. Monoculture fields were compared with double cropping fields cultivated with barley to investigate the impact of winter crop cultivation. Cropping system altered bacterial use of carbon sources, as reflected by the enhanced utilization of 2-hydroxy benzoic acid under monoculture conditions. CONCLUSION: These results show that soil use intensity and topological characteristics have a minimal impact on soil bacterial functioning in relation to carbon substrate utilization. Moreover, soil chemical properties were found to be important factors determining the physiological profile of the soil bacterial community in paddy fields.

Objectives : This study aimed to identify the factors that affect the utilization of Korean Medicine within the past year. Methods : I analyzed micro-data from the Korean Medicine Utilization Survey (2020), which surveyed the general public. "User (in last 1 year)" were defined as those who had used Korean Medicine within the past year, while "Non-user (in last 1 year)" were defined as those who had used it in their lifetime but not within the past year. I examined several factors, including general characteristics, perceptions of Korean Medicine, satisfaction with Korean Medicine, and intention for future utilization. I conducted the Rao-Scott chi-squared test and complex sample logistic regression analysis. Results : I analyzed a total of 3,762 respondents, of which 1,442 (36.3%) were User (in last 1 year) and 2,320 (63.7%) were Non-user (in last 1 year). User (in last 1 year) and Non-user (in last 1 year) differed significantly in terms of demographic characteristics, perceptions, and satisfaction with Korean Medicine. Women, the elderly, those with low education levels, non-married individuals, those with low-income, chronic diseases, and poor subjective health conditions were significant factors. Those who used Korean Medicine within the past year were more knowledgeable about Korean Medicine than those who had not used it recently, and recognized herbal medicine as safer. In terms of satisfaction, User (in last 1 year) were more satisfied than Non-user (in last 1 year). The more women, the older, the more aware of Korean Medicine, the safer they perceived herbal medicine, the more satisfied they were with its use, the better their subjective health condition, and the absence of chronic diseases, the less they experienced Korean Medicine. Conclusions : The study showed that positive experiences and perceptions of Korean Medicine increase the likelihood of its utilization. Individuals with better subjective health conditions and without chronic diseases have a lower possibility of using Korean Medicine.

Background: While there are many studies estimating the effects of private health insurance on various types of health care utilization, few have examined how such effects change in conjunction with important policy reforms in national health insurance (NHI). This study examined how the effect of private health insurance (supplemental and fixed cash benefit) on high-cost outpatient imaging test utilization changed following the expansion of magnetic resonance imaging (MRI) coverage in 2018, which is a key example of the NHI benefit expansion policy in recent years. Methods: Data from the 2017 and 2019 Korea Health Panel Survey, which contained information about healthcare utilization before and after the expansion of MRI coverage in 2018, were used. The incremental effect of private health insurance on high-cost outpatient imaging test utilization for each period were quantified and compared, with special attention given to the type of private health insurance. Results: While people with supplemental private health insurance were more likely to use high-cost outpatient imaging tests than those without, both before and after the expansion of MRI coverage, the incremental effect increased from 1.6% points in 2017 to 2.5% points in 2019. Conclusion: Benefit expansion in NHI does not necessarily reduce disparities in the use of health care between private health insurance subscribers and non-subscribers. The results of our study also suggest that the path through which private health insurance affects healthcare utilization may not be limited to the price mechanism alone but can be more complex.
