Design Research in Learning Loss Recovery Innovation to Prevent Dropout of Jiarawanon-utis 4th School

Design research in learning loss recovery innovation to prevent dropout students of Jiarawanon-utis4th school aims to 1) diagnoses the learning loss of school. 2) Design and develop an innovativeprototype to revive students' learning loss. 3) Analyze the effect of using the innovative model torehabilitate students' learning loss. The research results can be summarized as follows:1) The results of the analysis of students' learning loss found that most of the students were in thepromotion group followed by the recovery group, and risk dropout group respectively. Problemsencountered: Some students had to help their parents with their work. Some students lacked motivationto study online. In addition, teaching and learning were not interesting.2) Learning recession recovery innovation consists of 3 components: (1) Input consisted of learningrecession analysis and analysis of student needs. (2) Process consisted of designing a short-termrehabilitation by providing additional instruction in core subjects before the semester, Long-termrehabilitation design using Thongkwaw planting, Mental health enhancement using music and sports,Coordination of networks and stakeholders, Strengthening teachers' potential through PLC.Monitoring and evaluation. (3) Output was to check the experimental results of implementinginnovation with a reflection.3) The results of rehabilitation of learning recession showed that students had developed moreknowledge, skills and desirable characteristics which teachers and parents reflected from observingstudent behavior, such as being brave and like to answer teacher's questions, increasing homeworkassignments, students liked to come to school, absenteeism decreased, enjoyment of music and sports,no fighting behaviors, which showed increased readiness to study. Parents were satisfied with theimplementation of the learning recession recovery. Moreover, there were no students risk dropout

Evaluation of some important physicochemical properties of starch free grewia gum

Gums obtained by extraction from the inner bark of stems can be found in association with starch, which must be digested in order to obtain a refined polysaccharide isolate. In the present study, grewia gum obtained from the inner bark of the stems of Grewia mollis was shown to co-exist with starch and the effect of starch digestion on the physicochemical properties of the resultant polysaccharide was evaluated. The gum was extracted by maceration of the inner bark in deionized water and isolated by a combination of filtration, centrifugation and finally precipitation with absolute ethanol to produce the crude grewia gum extract (GG). The presence and content of starch in the gum sample was determined followed by enzymatic digestion of the starch using α-amylase (Termamyl 120L) to give a starch-free extract (GGDS). Physicochemical properties of the extracts such as total carbohydrates, total protein, differential sugar composition, NMR, intrinsic viscosity and rheological behaviour of the samples were evaluated. The GG extract had total carbohydrate content of ∼ 60 % out of which 11.8 % was starch, and a protein content of 2.3 %. Samples also contained galacturonic and glucuronic acid which were highly acetylated. Both samples had a higher proportion of galacturonic acid than glucuronic acid and contained rhamnose, arabinose, galactose, glucose and xylose as neutral sugars in varying proportions. Rheological measurements on 2 %w/w dispersions of the extracts show minor differences between both the original extract and the de-starched material but were influenced by changes in pH

Development of Type A Quadrupole Magnet for Siam Photon Source II

A prototype of a type A quadrupole magnet has been designed and manufactured for the 3 GeV storage ring of Siam Photon Source II, the second synchrotron light source in Thailand. The required quadrupole gradient is 51 T/m with the magnet effective length being 162 mm. Magnet modeling and magnetic field calculation were performed using Radia and Opera-3D. The bore radius of the magnet is 16 mm. The magnet will be operated at the excitation of 5544 A-turns. A mechanical analysis of the magnet structure was performed in SOLIDWORKS and ANSYS, where the maximum deformation of 0.003 mm was found at the magnet poles, and the first-mode natural frequency was higher than 100 Hz. The magnet yoke is made of AISI 1006 low-carbon steel with a fabrication tolerance of ±0.020 mm. Magnet coils are water-cooled and made of high-purity copper. The temperature rise of the coils was below 3.0 °C at the maximum excitation of 6664 A-turns, which is 20% above the operating point. Magnetic field measurement was carried out using the Hall probe technique. The measured magnetic field and coil temperature of the prototype show good agreement with the calculations

A New General Iterative Method for a Finite Family of Nonexpansive Mappings in Hilbert Spaces

<p/> <p>We introduce a new general iterative method by using the <inline-formula> <graphic file="1687-1812-2010-262691-i1.gif"/></inline-formula>-mapping for finding a common fixed point of a finite family of nonexpansive mappings in the framework of Hilbert spaces. A strong convergence theorem of the purposed iterative method is established under some certain control conditions. Our results improve and extend the results announced by many others.</p
