Examination anxiety is as old as examination itself, as long as examination exist, anxiety is bound to occur. Many students often feel anxious and exhibits lots of negative emotions towards examinations. These feelings of anxiety exhibited by the students generally has deleterious effects on the students and also on their academics and personality. This study therefore examined the use of Cognitive Behaviour Therapy and Relaxation technique on examination anxiety among Senior Secondary School students in the Ibadan metropolis. The moderating effects of emotional intelligence and academic self-efficacy were also examined. A pretest-posttest control group quasi- experimental design with a 3x2x2 factorial matrix was adopted. Multi-stage sampling procedure was employed. Three local government areas were randomly selected from Ibadan metropolis. One public secondary school were randomly selected from each of the local government area. Ninety (M=37; F= 53) Senior Secondary School students SS 1 and 2 were screened for the test anxiety and were randomly assigned to the Cognitive Behaviour Therapy (30) Relaxation Technique(30) and control group(30). Treatment lasted for eight weeks for the CBT and Relaxation Technique groups. Data were analysed using Analysis of Covariance and Multiple Classification Analysis at the 0.05 level of significance. The results indicated that there was significant main effect of treatments on examination anxiety of secondary school students. There was also significant main effect of emotional intelligence and academic self-efficacy on examination anxiety of secondary school students. Both CBT and relaxation technique were effective in managing examination anxiety among secondary school students. Counsellors and educational Psychologists should utilise these therapies to manage examination anxiety among students.

Chronic Opisthorchis viverrini-induced hepatobiliary disease is associated with significant leukocyte infiltration, including activated macrophages; however, the polarization of infiltrating macrophages remains to be fully characterized. In this study, we characterized macrophage polarization and phenotype in chronic O. viverrini-induced hepatobiliary disease in humans and hamsters using gene expression and histochemical analysis. Chronic O. viverrini infection and associated hepatobiliary diseases were associated with iron loaded M2-like macrophages in both humans and hamsters. This study provides suggestive evidence that iron loaded M2-like macrophages promote hepatobiliary disease in chronic O. viverrini infection.

In this research the development of unstructured grid discretization solution techniques is presented. The purpose is to describe such a conservative discretization scheme applied for experimental validation work. The objective of this paper is to better establish the effects of mesh generation techniques on velocity fields and particle deposition patterns to determine the optimal aerodynamic characteristics. In order to achieve the objective, the mesh surface discretization approaches used the VLA prototype manufacturing tolerance zone of the outer surface. There were 3 schemes for this discretization study implementation. They are solver validation, grid convergence study and surface tolerance study. A solver validation work was implemented for the simple 2D and 3D model to get the optimum solver for the VLA model. A grid convergence study was also conducted with a different growth factor and cell spacing, the amount of mesh can be controlled. With several amount of mesh we can get the converged amount of mesh compared to experimental data. The density around surface model can be calculated by controlling the number of element in every important and sensitive surface area of the model. The solver validation work result provided the optimum solver to employ in the VLA model analysis calculation. The convergence study approach result indicated that the aerodynamic trend characteristic was captured smooth enough compared with the experimental data. During the surface tolerance scheme, it could catch the aerodynamics data of the experiment data. The discretization studies made the validation work more efficient way to achieve the purpose of this paper.

A stepwise inertial control (SIC) scheme of a wind turbine generator (WTG) rapidly increases its constant output to support the frequency control if a large disturbance such as a generator trip occurs in a power grid. This helps to significantly arrest the frequency nadir, but causes significant reduction in the kinetic energy (KE) of a WTG. Thus, the output of a WTG should be rapidly reduced to restore the rotor speed. This might cause a second frequency dip. This paper presents a modified SIC scheme of a doubly fed induction generator (DFIG) to prevent a second frequency dip. The modified SIC scheme generates a reference signal that consists of the constant reference and the reference for maximum power point tracking operation. The former is analytically determined by considering the mechanical input power and electrical output power curves of a DFIG. The output of the proposed SIC scheme decreases with the KE of the DFIG and thus no second frequency dip occurs. The performance of the proposed SIC is investigated for a 100MW aggregated DFIG wind power plant using an EMTP-RV simulator. The results clearly show that the proposed SIC scheme significantly increases the frequency nadir without causing a second frequency dip.

Purpose: : To evaluate and compare visual acuity and reading speed for Korean language between a diffractive bifocal and trifocal intraocular lens (IOL) of the same material and haptic design. Methods: We reviewed the medical records of the patients who had undergone bilateral cataract surgery with bifocal IOLs (AT LISA 801) on the both eyes (bifocal group) and trifocal IOLs (AT LISA tri 839 MP, trifocal group). The main outcome measures were the uncorrected distance, intermediate, and near visual acuity (uncorrected distance visual acuity [UCDVA], uncorrected intermediate visual acuity [UCIVA], and uncorrected near visual acuity [UCNVA]) and corrected distance, near, and distance-corrected intermediate visual acuity (corrected distance visual acuity [CDVA], corrected near visual acuity [CNVA], and distance-corrected intermediate visual acuity [DCIVA]) at last postoperative follow-up month. Reading speeds for Korean language were measured to check near visual function. Results: Fourteen eyes (7 patients) were included in the bifocal group and 32 eyes of 16 patients in the trifocal group. There were no statistical differences between the two groups with respect to UCDVA, UCNVA, CDVA, and CNVA. However, UCIVA (0.35 vs. 0.22 logarithm of the minimum angle of resolution [logMAR], p < 0.01) and DCIVA (0.34 vs. 0.20 logMAR, p < 0.01) were significantly better in the trifocal group than in the bifocal group. The mean reading speed for logMAR 0.5 optotype (point 10) was 86.50 words per minute (wpm) in the bifocal group and 81.48 wpm in the trifocal group without a significant difference (p = 0.70). Conclusions: Trifocal IOLs provided the same level of distance and near visual acuity and reading speed as that of bifocal IOLs with better intermediate visual acuity

In this paper the development of unstructured grid discretization approach is presented. The objective of this study is to better establish the effects of mesh generation techniques and grid convergence on velocity fields and particle deposition patterns to determine the optimal aerodynamic characteristics. In order to achieve this objective, cell-centred and vertex-centred approaches are employed and compared with experimental data. The cell-centred approach result indicates that the aerodynamic characteristic was captured faster in the stall condition, although with a different trend after the stall condition compared with the experimental data. The vertex-centred approach result indicates that the aerodynamic characteristic trend captured is comparable to the experimental data. From the model an advance study can also be achieved for this vertex-centred discretization approach with discrete vertex variables in several important areas.
