PURPOSE To investigate the underestimation of field loss in functional field score (FFS) between the Goldmann isopters III-4e and V-4e in visually impaired patients, in order to develop a predictive model for the FFS(III-4e) based on FFS(v-4e) that adjusts for possible confounders. Although the visual field is generally evaluated using Goldmann isopter III-4e, it has the disadvantage that not a...

The security of pairing-based cryptosystems depends on the difficulty of the discrete logarithm problem (DLP) over certain types of finite fields. One of the most efficient algorithms for computing a pairing is the ηT pairing over supersingular curves on finite fields whose characteristic is 3. Indeed many high-speed implementations of this pairing have been reported, and it is an attractive ca...

A farmer field school programme aims to impart knowledge and promote new technology. The is expected enhance farmers’ performances. However, the empirical evidence remains unclear. few studies have examined impact of this on technical efficiency in Indonesia. current study specifically investigates causal Farmer Field School Integrated Crop Management (FFS-ICM) maize production We used a stocha...

the purpose of this study was to investigate the effect of farmers' knowledge and attitude regarding farmer field school (ffs) on biological control against rice stem borer in mazandaran province. the population of the study included all farmers residing in three villages of kohnedan, rangrizmahalleh and aliabad (n=121). a questionnaire was developed from reviewed literature. the content a...

elements of agricultural knowledge and information management(research, extension, farmers, ngo and …) to near together in appropriate process were used in farmer field school approach. the purpose of this study was to determine the effect of farmer field school (ffs) approach on agricultural knowledge and information management. the research population consisted of 420 farmers who participated...

Computing discrete logarithms in finite fields is a main concern in cryptography. The best algorithms known are the Number Field Sieve and its variants in large and medium characteristic fields (e.g. GF(p), GF(p)); the Function Field Sieve and the Quasi Polynomial-time Algorithm in small characteristic finite fields (e.g. GF(36·509)). The last step of the NFS and FFS algorithms is the individua...

The gold standard endpoint in trials of locoregionally advanced nasopharyngeal carcinoma (NPC) is overall survival (OS). Using data from a phase III randomized trial, we evaluated whether progression-free survival (PFS), failure-free survival (FFS), distant failure-free survival (D-FFS) or locoregional failure-free survival (LR-FFS) could be reliable surrogate endpoints for OS. Between July 200...

Farmer field schools (FFS) originally were developed for rice in Asia by the Food and Agriculture Organization of the United Nations (FAO) for teaching integrated pest management. These were season-long courses involving 25 farmers and a trained facilitator. The main focus was promoting learning by discovery, which included hands-on training activities such as insect zoos and the use of field e...

BACKGROUND This study examined the association between the physical work environment and physiological performance measures, physical activity levels and metabolic parameters among German civil servants. A main focus in this study was to examine the group differences rather than measuring the absolute values in an occupational group. METHODS We prospectively examined 198 male German civil ser...

Running research has focused on reducing injuries by changing running technique. One proposed method is to change from rearfoot striking (RFS) to forefoot striking (FFS) because FFS is thought to be a more natural running pattern that may reduce loading and injury risk. Muscle activity affects loading and influences running patterns; however, the differences in muscle activity between natural F...
