The unique varietal characteristics of SPR are pigmented, glutinous, good-yielding varieties planted in lowland areas. This study was conducted to increase farmers’ income through employing different promotion and extension activities and enterprise development. Data were analyzed using descriptive statistics. Cost and return and benefit-cost analysis were used to determine the financial benefits of using the SPR in different production systems. Results revealed that incorporating the following parameters is critical in the sustainable adoption of the SPR. Amongst them are: ensuring that recommended production technologies are strictly followed by the farmers, ensuring the quality of seeds for planting, the presence of a market for the produce, engaging the farmers in value-adding activities like processing, capability development in entrepreneurship, and adopting clustering approach of the farmers to address economies of scale in marketing and processing. The use of SPR produced an average yield of 6.11 MT/ha and 5.04 MT/ha during the dry and wet seasons from 2021-2023, respectively, higher than the usual varieties of inbred rice. The net benefit from producing a CLS-2 variety of SPR is higher than regular rice, having an average difference of Php 22,355.53 per hectare from 2021-2023.展开更多

Based ...To determine the dynamic influence range of emergencies under special events, the spacial and temporal characteristics of the traffic flow are studied by simulation based on the cell transmission model （CTM）. Based on the traffic management measures used under special events, a semi-dynamic assignment algorithm is proposed, which is combined with an algorithm for logit multi-path traffic assignment and the CTM. In a simple calculation network, the spacial and temporal characteristics of traffic flows which vary with different traffic management schemes are studied, and a method to obtain the influence range of emergency is proposed by computing the jam time of the intersections. By contrasting the average delay of each vehicle, the dissipation effect is studied under two different traffic management schemes. The example shows that the spatial and temporal variety of the traffic flow can be easily simulated and the influence range of emergency can be confirmed by the method based on the CTM. The proposed method provides a new idea for decision-making on traffic management under emergency under special events.展开更多

The strategies by which clonal plants adapt to this type of heterogeneous environment were examined in three stoloniferous herbs,Potentilla reptans L. var. sericophylla Franch., P. anserina L. and Halerpestes ruthenica (Jacq.) Qvcz., commonly inhabiting forest understories, grasslands and low saline meadows, respectively. As pairs of connected ramets were subjected to reciprocal patchiness of light and nutrients, stolon connection between the two ramets significantly enhanced biomass of both ramet growing in low light intensity but high soil nutrient condition (LH ramet) and ramet growing in high light intensity but low soil nutrient condition (HL ramet) as well as whole ramet pairs (consisting of LH ramets and HL ramets). Additionally, stolon connection greatly increased root/shoot ratio of LH ramet while significantly decreased that of HL ramet. The results indicate that a reciprocal transportation of resources between interconnected ramets and a functional specialization of ramets in uptake of abundant resources occurred. By resource sharing and functional specialization, clonal plants can efficiently acquire locally abundant resources and buffer the stress caused by reciprocal patchiness of resources.展开更多

文摘[Objectives]This study was conducted to promote the rational use of special use level of antibiotics in clinic and delay the emergence of drug resistance.[Methods]The application of antibiotics for special use among inpatients of a hospital in 2019 was analyzed.The data in the drug information management system of the hospital were queried,and the collected expert consultation records of special-use antibiotics were sorted out.Indicators including the use rate of special-use antibiotics,antibiotic use density(AUD),defined daily dose system(DDDs)and defined daily dose system cost(DDDc)of each drug,the annual pathogen detection rate,disease distribution and pathogenic microorganism detection were summarized and analyzed for inpatients in the hospital retrospectively.[Results]In 2019,the average annual use rate of special-use antibiotics in the hospital was 1.53%,and the average annual use density was 1.59 DDDs.The antibiotics with the top three DDDs were imipenem and cilastatin,meropenem and cefepime.The antibiotics with the top three DDDc were voriconazole dispersible tablets,voriconazole for injection,and meropenem for injection.The average annual detection rate of microorganisms was 85.77%.The diseases were mainly diagnosed as respiratory infections such as pneumonia and secondary infections after radiotherapy and chemotherapy before medication,and the detected pathogens were mainly Candida and its subspecies,Escherichia coli,and Klebsiella and its subspecies.[Conclusions]The clinical use of special-use antibiotics in the hospital was basically reasonable,but there were still some problems.It is necessary to increase management efforts,strengthen training for relevant medical personnel,and provide management ideas for further standardizing the use of antibiotics in the hospital.
文摘Objective:To study the application effects of the entire-course nutrition management model led by specialized nutrition nurses in patients with distant cholangiocarcinoma.Methods:Using convenience sampling,one hundred and twenty patients with distant cholangiocarcinoma admitted from April 2023 to October 2024 were selected as the experimental subjects of this study.They were grouped using a random number table method.The intervention group consisted of 60 patients with distant cholangiocarcinoma who received the entire-course nutrition management led by specialized nutrition nurses,while the observation group consisted of 60 patients who received conventional management.The intestinal function,nutritional indicators,quality of life,and satisfaction were compared between the intervention and observation groups.Results:After intervention,the intestinal function,nutritional indicators,quality of life,and satisfaction of patients with distant cholangiocarcinoma in the intervention group were significantly better than those in the observation group,with statistically significant differences(P<0.05).Conclusion:The application of the entire-course nutrition management model led by specialized nutrition nurses in patients with distant cholangiocarcinoma has more prominent effects and can further improve prognosis,making it worthy of widespread clinical application.

文摘Objective:To explore the effect of implementing a time-sensitive incentive model combined with specialized rehabilitation nursing in patients with severe pneumonia and respiratory failure.Methods:Seventy-eight patients with severe pneumonia and respiratory failure admitted from January 2024 to February 2025 were selected and randomly divided into two groups using a computer-based random drawing method.The control group(39 patients)received routine nursing,while the observation group(39 patients)received a time-sensitive incentive model combined with specialized rehabilitation nursing.Lung function and adverse emotional states were compared between the two groups.Results:After 2 weeks of nursing,the lung function of the observation group was higher than that of the control group(P<0.05),and the adverse emotional states of the observation group were lower than those of the control group(P<0.05).Conclusion:Implementing a time-sensitive incentive model combined with specialized rehabilitation nursing in patients with severe pneumonia and respiratory failure can improve lung function and emotional state.
文摘The reader might rightly ask for a word on the origin of this special issue of Cultures of Science. The topic of ‘common sense’(CS) arose from an international workshop organized in September 2017 in Beijing by the then newly founded NAIS(National Academy of Innovation Strategy). As part of the developments, this very journal, Cultures of Science, was about to be launched, and the aim of the workshop was to explore future topics and issues that the journal seeks to address.

文摘To determine the dynamic influence range of emergencies under special events, the spacial and temporal characteristics of the traffic flow are studied by simulation based on the cell transmission model （CTM）. Based on the traffic management measures used under special events, a semi-dynamic assignment algorithm is proposed, which is combined with an algorithm for logit multi-path traffic assignment and the CTM. In a simple calculation network, the spacial and temporal characteristics of traffic flows which vary with different traffic management schemes are studied, and a method to obtain the influence range of emergency is proposed by computing the jam time of the intersections. By contrasting the average delay of each vehicle, the dissipation effect is studied under two different traffic management schemes. The example shows that the spatial and temporal variety of the traffic flow can be easily simulated and the influence range of emergency can be confirmed by the method based on the CTM. The proposed method provides a new idea for decision-making on traffic management under emergency under special events.
文摘Environments with reciprocal patchiness of resources, in which the availability of two resources such as light and soil nutrients are patchily distributed in horizontal space and negatively correlated in each patch, are common in many ecosystems. The strategies by which clonal plants adapt to this type of heterogeneous environment were examined in three stoloniferous herbs,Potentilla reptans L. var. sericophylla Franch., P. anserina L. and Halerpestes ruthenica (Jacq.) Qvcz., commonly inhabiting forest understories, grasslands and low saline meadows, respectively. As pairs of connected ramets were subjected to reciprocal patchiness of light and nutrients, stolon connection between the two ramets significantly enhanced biomass of both ramet growing in low light intensity but high soil nutrient condition (LH ramet) and ramet growing in high light intensity but low soil nutrient condition (HL ramet) as well as whole ramet pairs (consisting of LH ramets and HL ramets). Additionally, stolon connection greatly increased root/shoot ratio of LH ramet while significantly decreased that of HL ramet. The results indicate that a reciprocal transportation of resources between interconnected ramets and a functional specialization of ramets in uptake of abundant resources occurred. By resource sharing and functional specialization, clonal plants can efficiently acquire locally abundant resources and buffer the stress caused by reciprocal patchiness of resources.
