Objective: This study aimed to determine the effects of indoor air pollution on workers and the effects of discharged gases, such as CO, CO2, NO2, O3, SO2, NH3, and PM, on the manifestation of bronchial reactivity during the process of gasification at the power plants in Kastriot, Kosovo. Methods: Parameters of lung function were determined using body plethysmography. Airway resistance (Raw) and intrathoracic gas volume (ITGV) were measured; based on these values, specific airway resistance (SRaw) and specific airway conductance were calculated. Results: The study was performed in two groups: the control group and the experimental group. The control group consisted of 32 healthy people, whereas the experimental group consisted of 55 workers of the gasification department of the power plants in Kastriot, Kosovo. The results of this study indicated that the mean value of SRaw significantly increased in the experimental group (p<0.05) compared to the control group (p>0.1). This study also showed that smoking is in favor of the negative effects of air pollution at the premises of the gasification department (p<0.01). Measurements of the respiratory systems were made before and following provocation with histamine–aerosol (1 mg/ml) in the control and experimental groups. Changes between these two groups following this provocation with histamine–aerosol were found to be statistically significant (p<0.01). Conclusion: Although air pollution requires time to cause a respiratory pathology, it permanently affects the manifestation of bronchial reactivity. This finding suggests that the real situation of these workers exposed to air pollution during the process of gasification poses a serious risk to their health and particularly to normal respiratory function.

The impact of air pollution with microparticles (PM2.5 and PM10) on the respiratory systems of workers engaged in thesurface mining of coal at the Bellaqevc power plants of Kosovo  is studied  in this paper. The parameters of lung functionare defined via body plethysmography. The resistance of the airways (Raw) was recorded, intrathoracic gas volume (ITGV) was measured, and the specific resistanceof the airways (SRaw) and specific conductance (SGaw) were calculated. The research was performed withintwo groups: a control group and experimental group. The control group consisted of 28 healthy people, whereas the experimental group consisted of 50 workers engaged in the surface mining of coal at the Bellaqevc power plants of Kosovo. The results obtained from this research indicated that the mean specific resistance (SRaw) was ​​significantly increased in the experimental group (p<0.01) compared to the control group (p>0.1). The study also found that smoking favors the adverse effects of air pollution caused by coalsurface mining at the Bellaqevc power plants (p<0.01). Measurements of the respiratory systems were made prior to and following provocation with histamine–aerosol (1 mg/ml) in the control and experimental groups. Changes between these two groups following this provocation with histamine–aerosol were found to be statistically significant (p<0.01). In order to cause a respiratory pathology from air pollution, it is required a lot of time, such pollution can permanently cause respiratory system disorders. These scientific findings suggest that the long-term exposure of workers to microparticles PM2.5 and PM10 during the processof surface mining coal at the Bellaqevc power plants of Kosovo  poses a risk to their health by causing increased bronchial reactivity, bronchial asthma, orchronic obstructive pulmonary disease (COPD).

Abstract Background The denial of death in Western society deprives young people of the tools to derive meaning from experiences of death and dying. Literature shows that death education may allow them to become familiar with this topic without causing negative effects. This article describes the effects of a death education course with adolescents, wherein participants were given the opportunity to meet palliative doctors and palliative psychologists at school and in a hospice, where they were able to converse with the families of the dying. Methods This study used mixed methods and included an evaluation of a death education intervention with longitudinal follow-up of outcomes. The course involved 87 secondary school students (experimental group) aged between 16 and 20 years. We also recruited a control group of 76 similarly-aged students to observe differences. The variables we examined were: alexithymia, representation of death, value attributed to life and spirituality. These were measured with the following instruments: the Toronto Alexithymia Scale-20, the Testoni Death Representation Scale, the Personal Meaning Profile and the Spiritual Orientation Inventory, respectively. To better understand how the students perceived the experience, we asked the experimental group to answer some open-ended questions. Their answers were analysed through thematic analysis. Results The study showed that death education and the hospice experience did not produce negative effects, but rather allowed students to decrease alexithymia, improving their ability to recognise and express emotions. Thematic analysis revealed that all participants perceived the experience as very positive. Conclusions Our findings affirm that death education programs can be successfully implemented in high schools, and that they can usefully involve local hospices and palliative care professionals, especially physicians and psychologists.

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.

This study employed a hierarchical linear model analysis to examine the effects of ego depletion and state anxiety on performance changes in golf putting. We randomly assigned 51 female college students with no previous golf putting experience to either an ego-depletion (experimental) group ( n = 26) or a non-ego-depletion (control) group ( n = 25). Putting performance changes over repeated trials displayed a quadratic curve, and both ego depletion and state anxiety exerted negative effects on early, but not late, putting performance. Contrary to previous findings, the interaction effect between ego depletion and state anxiety on performance was nonsignificant.

AIM: Blocking effect of leukotriene biosynthesis–zileuton and blocking the effect of phosphodiesterase enzyme–diprophylline in the treatment of patients with bronchial asthma and bronchial increased reactivity, and tiotropium bromide as an antagonist of the muscarinic receptor studied in this work.METHODS: Parameters of the lung function are determined with Body plethysmography. The resistance of the airways (Raw) was registered and measured was intrathoracic gas volume (ITGV), and specific resistance (SRaw) was also calculated. For the research, administered was zileuton (tabl. 600 mg) and diprophylline (tabl. 150 mg).RESULTS: Two days after in-house administration of leukotriene biosynthesis blocker–zileuton (4 x 600 mg orally), on the day 3 initial values of patients measured and afterwards administered 1 tablet of zileuton, and again measured was Raw and ITGV, after 60, 90 and 120 min. and calculated was SRaw; (p < 0.01). Diprophylline administered 7 days at home in a dose of (2 x 150 mg orally), on the day 8 to same patients administered 1 tablet of diprophylline, and performed measurements of Raw, ITGV, after 60, 90 and 120 min, and calculated the SRaw (p < 0.05). Treatment of the control group with tiotropium bromide - antagonist of the muscarinic receptor (2 inh. x 0.18 mcg), is effective in removal of the increased bronchomotor tonus, by also causing the significant decrease of the resistance (Raw), respectively of the specific resistance (SRaw), (p < 0.05).CONCLUSION: Effect of zileuton in blocking of leukotriene biosynthesis is not immediate after oral administration, but the effect seen on the third day of cys-LTs’ inhibition, and leukotriene B4 (LTB4) and A4 (LTA4) in patients with bronchial reactivity and bronchial asthma, which is expressed with a high significance, (p < 0.01). Blockage of phosphodiesterase enzyme–diprophylline decreases the bronchial reactivity, which is expressed with a moderate significance, (p < 0.05).

This study aimed to develop students' creativity through troubleshooting learning models in practical electro-pneumatic. This study was conducted during the Covid 19 pandemic where learning was carried out online. This troubleshooting practice learning is applied to simulation applications so that it can be a solution in implementing learning that cannot be carried out directly. This study used a quasi-experimental researched method with a controlled group pretest-posttest design pattern.  The sample consisted of 60 students majoring in mechanical engineering, State University of Semarang was divided into two classes.  The experimental class applies the troubleshooting-based practical learned model, while the controlled class implements practice learned without using the troubleshooting learned model. Based on the research result, the pretest mean value in the experimental group was 76.26 with a standard deviation of 11.97, while the pretest mean value in the control group was 74.53 with a standard deviation of 10.31. Meanwhile, the posttest mean score in the experimental group was 77.5 with a standard deviation of 7.62, while the posttest mean score in the control group was 64 with a standard deviation of 8.84. The average posttest score in the experimental group is higher than the control group so it can be concluded that the learning outcomes of the experimental class using a troubleshooting-based practical learning model are higher than the control class where troubleshooting learning models are not implemented in electro-pneumatic practice
