ABSTRACT Introduction: Chronic obstructive pulmonary disease (COPD) is a respiratory disease characterized by incomplete reversibility of airflow obstruction and persistent respiratory symptoms. Objective: To explore the therapeutic effect of physical exercise on patients with chronic obstructive pulmonary disease in pulmonary rehabilitation. Methods: Forty-eight experimental subjects were divided into control group, experimental group 1, and experimental group 2 for research. The control group received normal medical-related treatment without any other means of intervention. In addition to normal medical-related treatment, experimental group 1 received breathing training and educational interventions and experimental group 2 received exercise, breathing training and educational interventions. Results: The vital capacity of female subjects before and during the experiment ranged from 2.23±0.01 to 2.26±0.04, the FVC ranged from 2.00±0.02 to 2.01±0.03, the FEV1 ranged from 1.03±0.01 to 1.03±0.01,the FEV1% ranged from 55.50±1.29 to 55.25±1.71,the FEV1/FVC ranged from 51.44±0.24 to 50.84±1.00, andthe heart rate ranges from 65.00±0.82 to 65.50±1.29. Conclusions: Exercise training can increase the exercise tolerance of patients with COPD, relieve dyspnea, and improve the quality of life. Level of evidence II; Therapeutic studies - investigation of treatment results.

<p style="text-align: justify;">The effects of international phonetic alphabet (IPA) instruction on English as a foreign language (EFL) adult learners’ pronunciation have been well-recognized. However, not many studies on the topic were conducted in the Vietnamese context. Therefore, the current study aims to investigate (1) the impact of IPA learning on Vietnamese EFL adult learners’ pronunciation and (2) adult learners’ perceptions of the effects of learning the IPA system on their pronunciation. The study was designed as an experimental study, following a mixed-methods approach, using the pre-and-post-tests, questionnaires, and interviews to collect quantitative and qualitative data. Thirty-eight adult learners took part in this investigation; they were divided into two groups, nineteen in the control and nineteen in the experimental group. The experimental study lasted ten weeks before the questionnaires and interviews were administered with the participants in the experimental group. The results demonstrated a significant improvement in adult learners’ pronunciation in the experimental group. The participants in the experimental group also highly perceived the positive effects of learning the IPA system on their pronunciation. Pedagogical implications and suggestions were presented at the end of the paper.</p>

<p style="text-align: justify;">The purpose of the study was to identify what neuropsychological effect online learning had on psychology students and how it could be moderated. The study was descriptive and combined qualitative and quantitative methods to address the research questions. The study relied on three phases such as baseline study, experiment, and reporting. The experiment utilised neuropsychology tests adopted from the NeurOn platform. It was found that the Psychology students’ perceptions of e-learning and their emotional reaction to them were found not to be appreciative. The practices in breathing exercises, meditation, or yoga were proved to be able to moderate the impact of online learning on the experimental group students’ attentional capacities, memory processes, and cognition abilities. The above findings were supported by the results obtained for the neuropsychology tests and the experimental group students’ self-reflections yielded from the use of the MovisensXS App. The students confirmed that breathing exercises, meditation, or yoga reduced study stress and burnout caused by e-learning and improved their academic performance. The focus group online discussion also showed that integration of breathing exercises, meditation, and yoga helped the experimental group students keep emotional balance, concentrate on their studies easier, remember more information, and meet deadlines in completing assignments. The education scientists are suggested to study how the e-learning curriculum could be reshaped so that it used relaxation practices on regular basis.</p>

A newborn baby has only three demands. They are warmth in the arms of his mother, food from her breasts and security in the knowledge of her presence. Breastfeeding satisfies all three. While breastfeeding may not seem the right choice for every parent, it is the choice for every baby because it fulfills the physical needs as well as psychotic complementary of the child. The study aimedto find out the association of nipple soreness in experimental group and comparison group in terms of sample characteristics of postnatal mothers. A quasi experimental study was conducted on 70 postnatal mothers, (35 in experimental group and 35 in the comparison group) who breast feeds their babies were selected conveniently. Feeding pattern was assessed by LATCH scale four times in a day followed by the application of hind milk minimum four times in a day for three or four days as per discharge day of mother. The mother was asked to rub hind milk on nipples after feeding the baby and letting it air dry in front of researcher and nipple soreness scale was used to check the sore nipple at third and fifth day or at the day of discharge. Follow up of postnatal mothers was done telephonically by using interview questionnaire on day 15 in both groups. Study findings revealed that on 3rd day, the mean nipple soreness score was higher in comparison group (1.45) than experimental group (0.10) and thus there was significant difference (t value = 3.87) in nipple soreness score.Study concluded that breast milk application was effective in preventing sore nipples among postnatal mothers. Hence, it can be recommended to use breast milk for the prevention of sore nipple.

Abstract Background Regarding the high rate of obesity and overweight among women, develop a comprehensive and effective program it seems necessary to improve their nutritional behaviors and physical activity. This study aims to survey the effect of educational intervention based on the theory of planned behavior (TPB) on improving physical and nutritional activities of obese and overweight women. Methods This experimental study was performed on 400 obese and overweight women over the age of 20. The sampling method was A simple random sampling. The data collection was valid and reliable self-reports measure, questionnaires. This tools was including demographic information, questionnaire based on the constructs of the theory of planned behavior, physical activity performance questionnaire and nutritional performance questionnaire that individuals completed before and 6 months after the educational intervention. The training intervention for the experimental group consisted of 12 sessions of 50–55 min. Data analyzed by SPSS22 and by using chi-square test, independent t-test and paired t-test. Results Findings showed that before the educational intervention, was no significant difference between the experimental and control groups in terms of education, household monthly income, occupation, mean age, marital status, awareness, attitude, perceived behavioral control, subjective norms, physical activity and nutritional behavioral intentions, and physical activity and nutritional performance, weight and BMI. However, six months after the training intervention, there was a significant increase in each of the TPB contracts, weight and BMI in the experimental group, while no significant difference was observed in the control group. The meaningful level was considered 0.05. Conclusion Our findings partially support of applying theory of planned behavior in reducing the weight, BMI and improved nutritional performance and physical activity of the study subjects. TPB could be an important strategy for effective future educational interventions.

The aim of this exploratory experimental quantitative is to investigate the impact of the learning environment and text types on the syntactic complexity of female Saudi students majoring in English language. Specifically, the study seeks to explore how and when the syntactic complexity of these students increases/decreases as a whole and across the fourteen measures of syntactic complexity (MLS, MLT.MLC.C/S, VP/T, C/T, DC/C, DC/T, T/S, CT/T, CP/T, CP/C, CN/T, CN/C) in two learning contexts: traditional learning context (TLC) and blended learning context (BLT) across three writing tasks (argumentative, classification ,and reaction). It purports, also, to find out when and which learning context leads to the most/least increase/decrease in the syntactic complexity (as a whole and across specific measures) of Saudi undergraduate in the three writing tasks. To answer such questions, 48 female Saudi EFL undergraduate students were recruited from the pool of level six students. The participants were randomly divided into the control and experimental groups. The control group consisted of 28 students; while the experimental group was comprised of 20 students. The 288 students’ writing productions were analyzed according to the fourteen measures of syntactic complex by using a paired t-test and an independent t test. For the first question, the results of this study show that there was no increase/decrease in syntactic complexity, either as a whole or partially across individual measures, for the control group for the three writing tasks (argumentation, classification, and reaction). This would suggest that traditional learning method does not reach to level to be significant to the participants in the control group. For the second research question, the t-tests showed that the syntactic complexity of the participants in the experimental group increased as a whole in both the classification and reaction essays. An increase in complexity was shown across the following measures for the classification essay: MLS, MLT, MLC, CN/T/VP/T, and CN/C. For the reaction essay, an increase in complexity was shown across MLS, MLT, MLC, and CN/T measures. Although the syntactic complexity of these participants did not increase/decrease as a whole for the argumentation essay, the CN/T measure did show some increase. Finally, the comparison between the results of the two groups revealed that, although the experimental group in this study showed more improvement in syntactic complexity than the control group, the degree of difference between the two groups was too small to draw any definite conclusion about the relative effectiveness of the two methods. This may be due to the comparatively short duration of the study: ten weeks. The findings of this research have significant implications for academic research and for Saudi EFL teachers at the university level.

The effect of He–Ne laser irradiation on fishery parameters as well as on biochemical state, including the lipids and fatty acids, the activity of energy metabolism enzymes and the proteome in the blastula stage and in underyearlings of wild Atlantic salmon after irradiation at the cleavage stage/early blastula (considered as the stages when the cell has a high potential for differentiation) was studied. Low mortality rates of eggs were determined during embryogenesis, as well as increased weight gain and lower morality rates of underyearlings in the experimental group. This is confirmed by changes in a number of interrelated indicators of lipid metabolism: a decrease in total lipids content, including diacylglycerols, triacylglycerols, cholesterol esters, and the phospholipids content remained unchanged. The embryos in the blastula stage (experimental group) had higher aerobic capacity and an increase in pentose phosphate pathway activity. The proteome profiles of eggs in the blastula stage were 131 proteins, of which 48 were significantly identified. The major protein was found to be phosvitin. The proteomes of underyearlings were represented by 2018 proteins, of which 49 were unique for the control and 39 for the experimental group. He-–Ne laser irradiation had a strong effect on the contents of histone proteins.

Determining which forms of mineral feed additives can increase farm animal productivity is a key area of research. This study assessed the mineral composition of ruminal fluid and the effectiveness of calcium and phosphorus used by animals after the introduction of finely dispersed particles (FDP) of SiO2 (group I) and FeCo (group II) with a hydrodynamic radius of 109.6 ± 16.6 and 265 ± 25 nm, respectively. The deposition and use of calcium and phosphorus in the body of the experimental animals exceeded the control values. In group I, 30.8% more calcium was deposited (p ≥ 0.05), and in group II, the value was 30.3% (p ≥ 0.01). In the experimental groups, the calcium utilization rate was 27.3% higher in group I (p ≥ 0.05), and 28.2% higher in group II (p ≥ 0.01) compared to in the control. Phosphorus deposition was 34% higher (p ≤ 0.01) in experimental group I and 6% higher in experimental group II, compared with the control. Group I had a high utilization rate of phosphorus from the feed (with a 29% difference compared to the control). Comparison of the experimental groups revealed that the introduction of SiO2 FDP promoted an increase in the concentration of silicon, phosphorus, and calcium in the ruminal fluid. The introduction of FeCo FDP was accompanied by a decrease in the concentration of iron and cobalt in the ruminal fluid. Thus, the use of feed additive in finely dispersed form in the diet of animals was accompanied by an increase in the use of calcium and phosphorus by the animal’s body, which is advisable when intensifying milk and meat productivity. The obtained results require further research. Keywords: finely dispersed forms of microelements, ruminants, calcium and phosphorus exchange, feeding

Sports can cause the consumption of energy materials in the body. The rational use of nutritional supplements can maintain the homeostasis of the organism, which plays a very important role in improving the competitive performance of sports athletes. The purpose of this study is to explore the effect of nutritional supplements on basketball sports fatigue. The method of this study is as follows: first of all, 15 basketball players in our city were selected as the experimental objects, and they were randomly divided into the experimental group and the control group. The members of the experimental group took nutrients. After the training, 6 days a week, 3 hours in the morning and 3 hours in the afternoon, and the rest was adjusted on Sunday. Before training, four weeks and eight weeks of training, the blood routine indexes and body functions of athletes were tested. The results showed that the number of red blood cells, hemoglobin concentration, and average hemoglobin concentration of ligustilide supplement of the athletes were at the level of 0.05 after 4 weeks and 8 weeks, and the difference was significant ( P < 0.05 ). The nutritional supplements were used in sprint (3.4 s less), long-distance running (12.8 s less), and weight lifting (6.2 kg more) to a certain extent. Nutritional supplements are used as an auxiliary means of diet to supplement the amino acids, trace elements, vitamins, minerals, etc. required by the human body. The conclusion is that nutrition supplement can effectively improve the indexes of athletes’ body in about four weeks, but the effect is not obvious after a long time. This study provides a certain method for the research of nutritional supplements in the field of sports.

Introduction: Marital satisfaction is one of the most important signs of a favorable relationship between couples. This research aimed to survey the effectiveness of training using Bowen's family therapy approach on marital satisfaction of married women in the city of Aligodarz (In the west of Iran). Method: This study was a quasiexperi mental study using a pretest-posttest design with a control group. The statistical population consisted of counseling applicant married women in the city of Aligodarz in 2019. By convenience sampling, 30 married women were selected and participated in this study. After recording the subjects' scores in the pre-test stage, the experimental group was exposed to the intervention (training course), but no operations were performed on the control group. Data gathering was carried out using a demographic questionnaire and ENRICH marital satisfaction scale. Frequency, percentage, mean and standard deviation indices were used to describe and Chi-square test was used to examine the homogeneity of the two groups in terms of study variables and multivariate analysis of covariance were performed in SPSS 24 software with a significancel level of 5%. Results: Descriptive findings showed that the mean (standard deviation) of the total score of the marital satisfaction variable in the pre-test and post-test stages was 131.60 (26.89) and 142.81 (25.24) in the experimental group and 132.66 (24.09) and 132.26 (21.92) in the control group, respectively. The inferential findings showed that Bowen's family therapy approach has a significant effect on some of the dimensions of marital satisfaction (religious orientation, equality of women and men, children and parenting, sexual relation, financial management, conflict resolution, and marital satisfaction) (p< 0.05). On the other hand, this approach was not practical in improving other aspects of marital satisfaction (relationship with family and friends, leisure time, marital relationship, personality issues, and contractual responses) (p> 0.05). Conclusion: The present study results showed an increase in marital satisfaction of married women using the Bowen family therapy approach. Therefore, it is recommended to use Bowen's family therapy approach to improve women's marital satisfaction with family problems.
