This problem is attributed to challenges specifically low yield, low quality of produce, and significant post-harvest losses, particularly in a resource-scarce setting. This study aimed to help increase the farmers’ income in selected towns of Nueva Ecija through the promotion and use of special purpose rice production technology. Twenty (20) farmer-cooperators in three towns of Nueva Ecija were selected to demonstrate the production technology covering a total area of 4.75 hectares during the dry season, and 3.3 hectares during the wet season, both in 2023. Extension modalities such as training, techno-demo establishment, information material and technical assistance provision, and market linkage were undertaken to enhance their knowledge, attitude, and skills on special rice production and enterprise. The study utilized the descriptive quantitative method wherein the data were gathered through surveys, specifically personal interviews. Results showed that 70% of the farmer-cooperators were male and 60% were living below the poverty threshold. The farmers were 53 years old on average and engaged in farming as their primary source of income. The average yield of special purpose rice particularly the CLS-2 variety was higher (6.46 MT/ha and 6.22 MT/ha during dry and wet seasons, respectively) than that of inbred or non-special rice. The income per hectare from special purpose rice production per hectare was Php 75,420.00, which is higher than that of regular rice at Php 29,389.00, giving a higher benefit of Php 46,031.00. The technology adopters and area planted increased (from 6 to 9 and from 1.4 hectares to 2.75 hectares, respectively) in Licab, Nueva Ecija. The opposite was true in Sto. Domingo and Guimba, Nueva Ecija where farmers were discouraged by the marketing issues that arose.展开更多

In this paper,we takea utomobile users in urban areas as the research object,combine unsupervised learning and supervised learningm ethods to analyze their travel characteristics,and focus on the classification and prediction of automobileu sers’trip purposes. However,previous studies on trip purposes mainly focused on questionnaires and GPSd ata,which cannot well reflect the characteristics of automobile travel. In order to avoid the multi-dayb ehavior variability and unobservable heterogeneity of individual characteristics ignored in traditional traffic questionnaires,traffic monitoring data from the Northern District of Qingdao are used,and the K-meansc lustering method is applied to estimate the trip purposes of automobile users. Then,Adaptive Boosting(AdaBoost)and Random Forest(RF)methods are used to classify and predict trip purposes. Finally,ther esult shows:(1)the purpose of automobile users can be mainly divided into four clusters,which includeC ommuting trips,Flexible life demand travel in daytime,Evening entertainment and leisure shopping,andT axi-based trips for the first three types of purposes,respectively;(2)the Random Forest method performss ignificantly better than AdaBoost in trip purpose prediction for higher accuracy;(3)the average predictiona ccuracy of Random Forest under hyper-parameters optimization reaches96.25%,which proves the feasibilitya nd rationality of the above clustering results.展开更多

Using optical microscope, SEM, TEM, EDS and X-ray diffractometer, the microstructure and phase composition of aluminum rod were measured and analyzed. The results indicate that the content of rare earth element Ce is between 0.05% -0.16% in the aluminum rod for electrical purpose. Its tensile strength is enhanced to some extent. The research also discovers that the tensile strength is enhanced remarkably with impurity element Si content increases. Because influence of Si is big to the conductivity, the Si content should be controlled continuously strictly in the aluminum for electrical purpose. Adding rare earth element Ce reduces the solid solubility of Si in the aluminum matrix, and the negative effect of Si on the aluminum conductor reduces effectively. So the limit of in Si content in aluminum rod for electrical purpose can be relaxed moderately.展开更多

Participants were 59 subjects (19 males and 40 fe- males) with a mean age of 30.9 years (standard deviation, 12.1;range, 18 - 68 years). We used a mental arithmetic (MA) test as a goaloriented stressor;the test was supposed to be finished before a time limit expired without using pencil and paper. We used a PIL test to assess the intensity of personal meaning in one’s life, an interest in mental arithmetic test (IMAT) to assess the intensity of interest in the MA test, and an anxiety inventory (AI) to assess the anxiety level of before and during the MA test. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and nose tip temperature (NTT) were recorded before and after MA. We used logistic regression modeling to estimate the odds ratio (OR) of independent variables of age, sex, PIL test score, AI score, HR, SBP, DBP, and NTT before the MA test. Multivariate-adjusted models showed that PIL test scores prior to the MA test significantly predicted the observed changes in AI score and HR. Other variables were not significant predictors. In conclusion, we found that a firm PIL decreased anxiety under psychological stress as measured with the MA test, even with objective evaluation by others. Having a firm PIL also lowered the response of the sympathetic nervous system to psych0logical stress.展开更多

It is also the material foundation for sustainable forestry development in China. It is a timely topic of concern within the forestry community and touches the entire society. From a social economic point of view, the sustainable development has been promoted by the efficient use of the forest resources in a continuing improvement of the environment. The objective of the present analysis is to measure the effect of various factors, such as population, economic development and related policies on the use of the forest resources. The 29 provinces of Mainland China are classified in three regions, based largely on their level of economic development. For each region, the factors which affect the area of special purpose forests (SPF) are analyzed. Some recommendations are made for further improvement.展开更多

文摘The present study was performed to clarify the influence of having a firm purpose in life (PIL) on psychological and physical stresses. Participants were 59 subjects (19 males and 40 fe- males) with a mean age of 30.9 years (standard deviation, 12.1;range, 18 - 68 years). We used a mental arithmetic (MA) test as a goaloriented stressor;the test was supposed to be finished before a time limit expired without using pencil and paper. We used a PIL test to assess the intensity of personal meaning in one’s life, an interest in mental arithmetic test (IMAT) to assess the intensity of interest in the MA test, and an anxiety inventory (AI) to assess the anxiety level of before and during the MA test. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and nose tip temperature (NTT) were recorded before and after MA. We used logistic regression modeling to estimate the odds ratio (OR) of independent variables of age, sex, PIL test score, AI score, HR, SBP, DBP, and NTT before the MA test. Multivariate-adjusted models showed that PIL test scores prior to the MA test significantly predicted the observed changes in AI score and HR. Other variables were not significant predictors. In conclusion, we found that a firm PIL decreased anxiety under psychological stress as measured with the MA test, even with objective evaluation by others. Having a firm PIL also lowered the response of the sympathetic nervous system to psych0logical stress.
