The different types of defects of half grouting sleeves will remarkably increase the risks of precast concrete structures. In order to better understand the defects of rebar connections between half grouting sleeves, six different test groups on insufficient grout height, insufficient compactness, rebar offset, insufficient rebar anchor length, overtime grouting, and control group had been researched. The uniaxial tension experiments were conducted for the 24 different specimens, and load-slip curves were also analyzed. The results of the experiments showed that the outside of the rebar was snapped off as for the destruction mode, while the destruction mode changed as the increment of the degree of defect surpasses the critical value. The bearing capacity and deformability were dropped with the increase in the degree of defects, and a critical value of rebar anchoring length of sleeve was discovered. In the end, different finite-element models were built based on different deficient situations, and load-slip constitutive model was obtained, which would be helpful to evaluate the structural performance of precast concrete structures in construction.

Thinking disturbance and disorder of affects may be different in two subtypes of schizophrenia, the “florid” and the “withdrawal” syndromes. In Exner's approach to the Rorschach system, the diagnostic indicators of disordered thinking may point out large differences not only between schizophrenic and control subjects but also between different types of schizophrenics. The Rorschach protocols of 45 subjects (15 “florid” schizophrenics, 15 “withdrawn” schizophrenics, and 15 controls of the same age and education, matched by sex) were examined on several Exner indices. Compared with the control group, both schizophrenic types confirmed an impairment of perceptual accuracy and of reality testing as well as a reduced emotional control. Compared with the “withdrawn” group, the “florid” schizophrenic subjects showed significantly higher indices of poor perceptual functioning, of an inadequate organizational activity (more Whole and Z responses characterized by negative Form Quality) and greater disordered ideational production.

This study aimed at investigating whether or not there was any significant effect on students’ listening competency who were taught by dictogloss strategy and those who were taught by conventional strategy. The population of this study was the tenth grade students in SMA N 1 Sukasada. Two classes were taken as samples in this study using cluster random sampling technique. They were assigned as experimental group and control group by lottery. To obtain the required data, the two groups were given different treatments. The experimental group was taught by using dictogloss strategy, meanwhile the control group was taught by using conventional strategy (cloze listening strategy). To collect the data the instruments used in this study were the teaching scenario and post-test in the form of listening test. The obtained data were then analyzed descriptively and inferentially. The result of inferential statistics showed that the t-observed exceeded the t-critical value. Thus, the null hypothesis was rejected, which means there was significant effect on students’ listening competency who were taught by dictogloss strategy and those who were taught by conventional strategy.

Aim. To assess food patterns in patients with different types of SIBO and their impact onto the course and treatment outcomes. Materials and methods. The data of 988 patients who signed informed consent surved as a source data. On the basis of lactulose breath test (LBT; GastroCH4eck, Bedfont, UK), the patients were selected into one of the studied groups: SIBO-H2, SIBO-CH4, SIBO-CH4-H2 and control. Twenty - four hours food recall test was used to analyze nutritional habits. In patients with SIBO-H2, standard treatment with Tilichinol 100 mg/Tilbrochinol 200 mg (Intetrix, Beaufour-Ipsen International, France) 2 caps BID for 10 days) was provided. Efficacy of treatment was assessed on the bass of the result of LBT 2 month after treatment completion. Mann-Whitney T test (Statistica 10, StatSoft, USA) was used to compare nutritional patterns in patients with or without SIBO, in different types of SIBO and in accordance to the results of treatment. Results and discussion. Nine hundred eighty eight patients were enrolled. On the basis of hydrogene breath test they were divided into 4 main groups: SIBO of hydrogen - producing flora (SIBO-H2, n=526), methane - producing flora (SIBO-CH4, n=129), SIBO with hyperproduction of methane and hydrogene (SIBO-CH4-H2, n=225). The control group consisted of 108 patients with no no excessive gas production on LBT. In contrast to controls, nutritional patterns of patients with SIBO were characterized by low dietary fiber and amount of red meat dishes in the rations. Those with SIBO-CH4 consumed more fruits (p=0.03), vegetables (p=0.003), and fish (p=0.026), compared to those with other variants of SIBO and the control group. Nutritional patterns of SIBO-H2 group were characterized by larger amount of poultry meat consumption (p=0.026) compared to other SIBO groups and controls. In SIBO-H2 “cured” group greater amounts of buckwheat (p

ABSTRACT Objective: To analyze reformatted sagittal sternal tomography images and classify sternal body curvature types, and compare different types of pectus populations with one another and with normal individuals. Methods: In total, 50 controls and 167 pectus patients were selected for chest CT to analyze the median sagittal plane, of whom 89 had pectus carinatum (mean age, 12 ± 10 years) and 78 pectus excavatum (mean age, 14 ± 10 years). Clinical types of pectus were classified as inferior, superior, or lateral pectus carinatum, and localized or broad pectus excavatum. The following types of sternal patterns were defined: gradual vertical curve, gradual posterior curve, gradual anterior curve, proximal third curve, middle third curve, distal third curve, anterior rectilinear, vertical rectilinear, and posterior rectilinear. Statistical analyses were performed to compare the different types of pectus with one another and with the control group. Results: Patients with different thoracic deformities, but with similar sternal curvature patterns, were observed. Some types of sternal curvature were significantly more frequent in certain types of pectus (p < 0,05). The gradual vertical curve and anterior rectilinear types prevailed in controls (p < 0,05). Conclusion: Some sternal curvature patterns were more frequent than the others in certain types of pectus and the controls. Level of Evidence II, Prognostic studies - investigating the effect of a patient characteristic on the outcome of disease.

Background: To use the meta-analytic approach to assess the effectiveness of different types of movement programs on motor competence (MC) in participants of all ages. Methods: Studies were retrieved by searching 13 databases and included when criteria were met. Studies were selected, and data were extracted by 2 authors. Random effects models using the standardized mean difference effect size (ES) were used to pool results. Risk of bias, heterogeneity, and inconsistency were examined. Results: Thirty-six studies met the inclusion criteria. A total of 374 ESs were calculated and partitioned into 4 groups (motor intervention, free play, physical education classes, and control group). Statistically significant improvements in MC were observed for the motor intervention (ES = 1.50; 95% confidence interval [CI], 1.18 to 1.82; n = 36), as well as for free play (ES = 0.33; 95% CI, 0.09 to 0.57; n = 5), physical education classes (ES = 0.52; 95% CI, 0.08 to 0.97; n = 15), and smaller statistically significant differences in MC were observed for the control groups (ES = 0.16; 95% CI, 0.01 to 0.31; n = 6). Conclusions: All 4 groups analyzed improved MC in children, adolescents, and young adults. However, motor interventions were superior to all other groups for improving MC.

Teaching reading comprehension for young learners becomes a challenge for English teachers in Indonesia. Dealing with that problem, this study had a purpose to investigate whether there was any significant effect on students’ reading comprehension taught by using big book and conventional media or not. Post-test only control group was used as the design with forth grade students of SD Laboratorium Undiksha Singaraja as the population. The data were analyzed descriptively and inferentially. As the result, it can be concluded that big book gives significant effect on students reading comprehension compared with the control group. It can be proven from the difference of mean score gained by experimental group (83.56) and control group (76.19). The result of the t-test also shows that the t-observed exceeded the t-critical value (4.088 > 2.042).

The aim of this study was to determine the effect of a single physical load of different duration and intensity on cognitive function. Material and Methods. The study population comprised 90 male soldiers. The subjects were randomly divided into two groups: experimental (n=60) and control group (n=30). The soldiers in the experimental group undertook 3 specific loads of different types, durations, and intensities. Attention concentration and tapping tests were carried out, and the reaction time was measured. Results. After the physical load, the soldiers in the experimental group performed the attention concentration test faster, the number of committed mistakes decreased, and the rate of processing information increased as compared to the corresponding values before physical load (all P<0.05). However, the indices of fatigue, such as the tapping test score and reaction time, in the experimental group were found to be worse than before physical loads (P<0.05). No significant changes were observed in the control group of soldiers. Conclusion. Despite fatigue, a single physical load of different duration and intensity improved the cognitive function.

This study aimed to evaluate the effects of different types of exercise on memory performance and memory complaint after a 12-week intervention. Eighty community-dwelling volunteers, aged 66.96 ± 11.73 years, were randomly divided into four groups: resistance, cardiovascular, postural, and control groups (20 participants for each group). All participants were tested for their cognitive functions before and after their respective 12-week intervention using Rey memory words test, Prose memory test, and Memory Complaint Questionnaire (MAC-Q). Statistical analysis showed that the three experimental groups significantly improved MAC-Q scores in comparison with the control group (p < .05). The variation of MAC-Q scores and the variations of Rey and Prose memory tests scores were not correlated. These results indicate that the 12-week interventions exclusively influenced memory complaint but not memory performance. Further investigations are needed to understand the relation between memory complaint and memory performance, and the factors that can influence this relationship.
