Journal of Computer and Communications 2019年第7期7卷 243-251页

作者： Arnold P. dela Cruz Gilbert m. Tumibay Nueva Ecija University of Science and Technology Cabanatuan City Philippines Graduate School Angeles University Foundation Angeles City Philippines Angeles University Foundation Angeles City Philippines

Tuberculosis remains an important problem in public health that threatens the world, including the Philippines. Treatment relapse continues to place a severe problem on patients and TB programs worldwide. A significant reason for the development of decline is poor compliance with medical treatments. The objectives of this research are to generate a predictive data mining model to classify the treatment relapse of TB patients and to identify the features influencing the category of treatment relapse. The TB patient dataset is applied and tested in decision tree J48 algorithm using WEKA. The J48 model identified the three (3) significant independent variables (DSSm Result, Age, and Sex) as predictors of category treatment relapse.

An Efficiency Assessment of Tuberculosis Treatment on Health Centers: A Data Envelopment Analysis Approach

引用

Journal of Computer and Communications 2019年第4期7卷 11-20页

作者： Arnold P. dela Cruz Gilbert m. Tumibay Nueva Ecija University of Science and Technology Cabanatuan Philippines Graduate School-Angeles University Foundation Angeles Philippines Angeles University Foundation Angeles Philippines

This study utilized Data Envelopment Analysis (DEA) in assessing the efficiency of health center in tuberculosis (TB) treatment. Assessing the efficiency of health center treating TB is a vital and sensitive topic, because there is a cumulative amount of public funds devoted to healthcare. In this research, a DEA model has been correlated to evaluate and assess the efficiency of 17 health centers. The researchers selected the health budget and the number of health workers as input variables likewise, the number of people served, number of TB patients served, and TB patients treated (%) as output variables. Based on the result of the study, only five (5) health centers out of seventeen (17) have 100% efficiencies throughout the 2 years period. It is recommended that other health centers should learn from their efficient peers recognized by the DEA model so as to increase the overall performance of the healthcare system. Likewise, health centers should integrate Health Information Technology to deliver healthier care for their patients.

Association mapping for Drought Tolerance of Rice (Oryza sativa L.) at Vegetative Stage

Agricultural Science & Technology 2012年第7期13卷 1385-1394页

作者：肖宇龙余传元雷建国 Quirino D. dela CRUZ Jonalyn m. YABES Dindo A. TABANAO 江西省农业科学院水稻研究所江西南昌330200 中吕宋国立大学菲律宾农业部水稻研究所植物育种和生物技术系

[Objective] This study aimed to identify possible quantitative trait loci (QTL) for vegetative drought tolerance traits of rice (Oryza sativa L.). [method] A total of 184 rice genotypes were field screened and 156 SSR markers randomly distributed at each 3 mb bin were used through genome-wide scanning method and association analysis to detect QTLs for vegetative drought tolerance traits leaf rolling (LER), leaf drying (LED) and drought recovery rate (DRR). [Result] The experimental rice genotypes showed varied response under vegetative drought, LER, LED and DRR were highly correlated. Population structure was detected at K=3 and K=7, certain extent of admixture existed in the experimental rice genotypes, relative kinship of the rice genotypes ranged from 0 to 0.924 5. Significant linkage disequilibrium among SSR markers was detected. Sixteen SSR markers have been detected to be associated with vegetative drought tolerance traits, four for LER, eight for LED and four for DDR. most of the markers were associated with more than one trait, indicating a single mechanism might involve in expression of several related traits, i.e. osmotic adjustment. Rm107 (Chr.9) was associated with all the three traits and fell exactly within or closely nearby to previous reported regions, was a major QTL for vegetative drought tolerance, Rm477 (Chr.8) was significantly associated with DRR and extremely significantly associated with LER was probably another major QTL for vegetative drought tolerance. [Conclusion] Association mapping is a very effective method for describing complex traits like drought tolerance.

育种的成功基于试验材料中具有可利用的遗传变异,了解种质资源的群体机构及遗传变异范围是作物遗传改良的先决条件。本试验通过利用每3 mb bin均匀分布于水稻染色体的156个SSR标记子,分析了一组(184个)用于干旱适应性研究的水稻种质资源的遗传相似性及群体结构。结果显示,水稻中确实存在着可供利用的遗传多样性,但也存在着普遍的遗传相似性,如国际水稻所的IR品种及菲律宾国家水稻所的PR及BP水稻品种。通过利用Structure中的混合模型对该184个水稻品种在K=3和K=7时的分析表明,群体结构普遍存在于相同类型或亚种的水稻品种中,籼稻及粳稻品种具有相对明显的群体结构,同一亲本的衍生后代具有显著的遗传相似性和群体结构,不同的群体均存在一定程度的遗传混合。对该组干旱适应性水稻种质资源的遗传相似性及群体结构的研究为今后的抗旱性基因的联合作图,也为合理选择亲本进行水稻抗旱性改良提供了有价值的遗传信息。
