The present research is an investigation of the role played by pronunciation instruction in the discrimination of English CVC and CVCV syllabic patterns in word-final position. The participants of this study were two groups of Brazilian learners (beginners): the control group (10 students), and the experimental group (12 students). Both groups were given a discrimination pretest and posttest, between which the experimental group received instruction based on a pronunciation manual with activities focused on the English syllable and word-final consonants, whereas the control group received no such instruction. The pre and posttests consisted of an oddity discrimination test, in which the participants had to discriminate between the CVC and CVCV syllabic patterns. The posttest results showed somewhat greater improvement for the experimental group than for the control group, but this difference was not statistically significant.

The increase in the prevalence of bullying and cyberbullying in recent years worldwide is undeniable. Although several intervention programs oriented towards the reduction of bullying and cyberbullying have been developed and implemented, significant disparities have been found regarding their efficacy. In most of the cases, the lack of the implementation of interventions involving all of the school community could be on the basis of this limited efficacy. The present study aimed to evaluate the effectiveness of the TEI Program, an intervention based on peer tutoring, in the reduction of bullying and cyberbullying, and in the improvement of school climate. The design of the study was quasi-experimental, in which 2057 Spanish students (aged 11 to 16 years) participated from 22 schools, and were randomly assigned to the experimental group (10 schools, 987 students) or the control group (12 schools, 1070 students). The obtained results showed a significant reduction in bullying behavior, peer victimization, fighting, cyberbullying and cybervictimization in the experimental group after the intervention implementation. Similarly, a significant improvement in factors of school climate was found only in this group. The obtained results demonstrated that the TEI program is effective in reducing bully and cyberbully behavior, and at the same time, improving the school climate.

To study the possibility and effectiveness of using succinylated gelatin (SG) for injecting endoscopic hemostasis. Material and methods. 70 albino non-linear rats. 0.5 ml of the solution has been injected into the anterior wall of the stomach with a syringe after laparotomy. A mixture of 0.9 % NaCl solution and epinephrine hydrothartrate (1.8 mg/1 ml) has been used in a ratio of 1:20 for the control group (35 animals). A mixture of a solution of SG (40 mg/1000 ml of injection water) and epinephrine hydrothartrate (1.8 mg/1 ml) in a ratio of 1:20 for the experimental group (35 animals). Right after the injection and in 1, 3, 6, 12 hours, after laparotomy, the stomach wall has been taken for histological examination, during which the thickness of the stomach wall (TSW) has been determined. Results. As soon as the injection has been given, the TSW in animals of both groups hasn`t differed significantly. The TSW has significantly increased in both of the groups, and the parameters of indicators in the experimental group have significantly raised in 1 h after the injection. In 3, 6, and 12 hours, the TSW in both groups has been decreasing. The parameters of indicators in the experimental group of animals have been significantly higher than in the control one all the time during the study. The indicators have barely differed from the initial ones in the control group 12 hours later, whereas in the experimental one they have been significantly higher. Histological studies have shown that the structure of stomach tissues in both groups hasn`t varied. The SG injection has not caused any negative effects on the tissues of the stomach wall. The thickness of the submucosa hasn`t been much modified right after the injection. The thickness (26.95±5.34 microns) has increased in the experimental group 12 hours later than in the control one (15.45±4.38 microns, p<0.01). Most of the vessels of the experimental group have remained compressed 12 hours later, whereas the diameter of the vessels of the control group has been growing. Conclusions. 1. The TSW hasn`t differed right after the injection (a mixture of 0.9 % NaCl and epinephrine solution and a mixture of SG and epinephrine solution) into the stomach wall. 2. 1 h later after the injection, the TSW has increased and its parameters after injection of a mixture with SG have been significantly higher. 3. In 3,6,12 h and later on, the TSW has been gradually reducing and its parameters after injection of a mixture with SG have been significantly higher each time. The thickness of the submucosa and the degree of compression of the vessels have also been considerably higher. 4. No negative changes in the structure of stomach tissues after injection of the mixture with SG have been detected. This allows it to be used for performing endoscopic hemostasis by injection therapy in clinical conditions.

Purpose. The aim of this study was to investigate and quantify changes in the newborn rats retinal layers during the hyperoxia (80% O2) exposure using fractal analysis. Materials and Methods. This study was conducted on two groups of 20 newborn rats: a control (normal) group (10 rats) and an experimental group (10 rats). The control group was composed of 10 newborn rats, which were placed at 12 hours after birth, in a pediatric incubator, together with their mother, in conditions of normoxia for 21 days. The experimental group consisted of 10 newborn rats, which were placed at 12 hours after birth, in a pediatric incubator with their mother, in conditions of normoxia for 7 days, then 7 days of hyperoxia (80% O2) for 22.5 hours/day, and then 7 days in conditions of normoxia. Slaughtering of the rats was performed on day 21 and the eye globes were harvested in order to perform histopathological examinations. The fractal analyses of the retinal digital images were performed using the fractal analysis software Image J, and the fractal dimensions were calculated using the standard box-counting method. Results. Microscopic examination revealed a normal development of the retina in the control group. In the experimental group, all the animals exposed to hyperoxia revealed both structural and vascular abnormalities on entire retina. Conclusions. The results showed that the fractal analysis is a valuable tool to quantify histoarchitectural changes in the newborn rats retinal layers during the hyperoxia (80% O2).

Nine subjects (experimental group) were tested on rapid elbow flexion and extension movements performed in the same final position, before and after extensive practice of the movements. Nine additional subjects (control group) were also tested, but without any practice between the tests. Comparison of the pretest and posttest results suggested that the experimental group decreased their variable error (i.e., standard deviation of the final movement position) in both practiced (elbow flexion) and nonpracticed (elbow extension) movements. The control group, however, did not improve in either of tested movements. The experimental group demonstrated lower variable error in the nonpracticed elbow extensions than the control group, while the same difference for practiced elbow flexion movements was slightly below the level of significance. The results support the importance of the final position in programming of rapid, self-terminated movements; however, they do not rule out the role of other kinetic and kinematic variables (such as movement distance).

The main objective of this research is to determine teacher competency requirements that support appropriate learning methods and be able to increase students' high learning desires and establish good learning facilities to determine the achievement of quality graduates and love knowledge. This study is expected to investigate how competencies, learning methods and ideal learning infrastructure can be used to improve students' understanding and comfort of teaching and learning processes that support intellectual quality and love knowledge. This notion arose after discovering that teaching practices for the affective domain were ineffective. Students learn to pass examinations, not to love knowledge. Experiments are conducted for 1 (one) year or 2 semesters, in January - December 2019, to determine the impact of learning experiences on students' academic achievement. The research sample consisted of 10 English teachers and 20 students from the Vocational High School. The students are divided into two groups; the control group (10 students) and the experimental group (10 students). Both groups were taught the same topic and learning objectives for 2 hour. However, the control group was taught using lecture slides, group discussions and closed with a question and answer session. Meanwhile, the experimental group is taught using new instructional instruments that adapt learning experiences that are appropriate to the curriculum. During the teaching session, the teacher observes student participation in all their activities and behavior during the lesson session. To complete this study, tests are conducted to see the impact of the learning experience on students' academic achievement.

The article discusses the results of the dy-namics of indicators of innate immunity of cattle throughout pregnancy. The research topic is relevant, since receiving healthy offspring is certainly associated with the natural resistance of the cow. The aim of the study is to study the non-specific immunity of cows in different months of pregnan-cy. The work was performed on the farm of JSC Krasnoselskoye PZ (Leningrad Oblast). During the experiment, 2 groups of cows of Holstein black-and-white breeds were formed: the experimental group – 10 preg-nant cows and the control group-10 not steel cows. Blood was taken once a month throughout pregnancy. Indicators of phago-cytosis, bactericidal and lysozyme activities were determined in the blood. During the study, the authors noted a decrease in lyso-zyme, bactericidal activity relative to the indicators of the control group, however, the difference did not reach significant differences. Also observed a sig-nificant inhibition of the functional state of the number of blood neutrophils: a decrease in phagocytic activity reliably observed from 5 months by 27.02%, from 7 month by 41.9% to 9 month, the index decreased by 50,66% as compared to control; at the phag-ocytic number of reliable decrease was ob-served at 4 months 11.3% at 6 months had decreased by 24.86%, and the 9 month preg-nancy reduction made up 28.81%, the phag-ocytic index, starting with the 5th month of pregnancy was significantly decreased by 32.05%, to 8 month decreased by 48.31% and for 9 months had decreased by 50% compared to control. Therefore, in the period of pregnancy in the organism of cows, the development of sec ondary immunodeficiency is noted, which is directly associated with fetal gestation. The data obtained can be useful in correction factors of natural resistance during pregnancy of cows.

Background. The aim of the study was to evaluate the effectiveness of physiotherapy combined with electro stimulation, for patients with spinal disc herniation in lumbar part. Methods. The study involved 38 people, 18 men and 20 women. The average age of all subjects was 29.84 ± 4.65 years. All subjects participated in the study for eight weeks, 30–45 minutes, three times a week. They were randomly divided in to three groups: two experimental and one control group. The first experimental group (12 people) participated in physical therapy combined with electro stimulation; the second experimental group (14 people) participated in physical therapy combined with placebo (fake) electro stimulation, and the third (control) group (12 people) participated in physical therapy treatments. All groups before and after the treatment performed trunk (flexor, extensor, lateral musculature) muscular endurance tests (McGill), analogue pain scale evaluation, and SF – 36 questionnaire. Results. After eight weeks of physical therapy combined with electro stimulation average numbers of analogue pain scale results decreased statistically significantly by 2.17 ± 1.11 (p < .05), trunk extensors (33.00 ± 12.78), flexors (31.67 ± 9.15) and lateral left (20.25 ± 2.80) / right (19.50 ± 3.71) musculature differences were statistically significant (p < .05). Physical therapy and placebo (fake) electro stimulation group and physical therapy group did not show statistical significance for all the tests except for analogue pain scale test (1.29 ± 0.83 and 1.92 ± 1.08). Conclusion. Physical therapy combined with electro stimulation applied for eight weeks for 25–39-year-old adults suffering from lumbar part disc herniation is an effective way to enhance trunk flexors, extensors, right/left lateral muscular endurance and reducing lumbar part back pain.

Abstract Abstract 2144 Poster Board II-121 The yield of CD34+ cells collected by apheresis for autologous peripheral blood stem cell (PBSC) transplantation was greatly increased when the appropriate timing was determined to begin using G-CSF after COAEP mobilization. 29 patients with lymphoma or multiple myeloma (MM) received the same mobilization chemotherapy, including CTX 400mg/m2 d1; VDS 2 mg/ m2 d1; Ara-C 60 mg/m2 ×5d; vp-16 60 mg/m2 ×5d; and prednisone 40 mg/m2 ×5d. The control group (12 cases) received subcutaneous G-CSF (filgrastim) at the first restoration after the initial nadir of the peripheral WBC count. The experimental group (17 cases) received G-CSF during the steady rise of the WBC count (end of fluctuating after initial nadir). G-CSF was given in a single daily subcutaneous dose of 300μg until the final PBSC apheresis.When the peripheral WBC and mononuclear cell (MNC) counts reached 10.0×109/Land 1.0×109/L, respectively, leukapheresis was carried out using the COBE Spectrablood cell separator. Despite comparable treatment with alkylating agents, a significantly increased yield of CD34 positive cells was observed in the experimental group (32.0×106/kg) compared to the control group (3.1×106/kg) (P=0.0182). This result indicates the importance of appropriate timing for the use G-CSF after mobilization chemotherapy to increase the CD34+ cell yield. Disclosures: No relevant conflicts of interest to declare.

This paper reports on a study that attempted to examine the effect of explicit pronunciation instruction of some English segments (individual sounds) on the degree of perceived foreign accent in EFL Arab learners’ speech. Nine Arab learners of English in an EFL (English as a foreign language) setting were assigned to two groups, experimental and control. Five utterances loaded with the taught segments were collected from both groups before and after instruction. While the experimental group received instruction on these segments, the control group did not. 13 native English listeners were recruited to rate all the elicited sentences for the degree of perceived foreign accent. The results did not show any effect of explicit pronunciation instruction on the degree of perceived foreign accent, as there were no differences between the ratings before and after the instruction.
