Retomando un concepto de la antropóloga R. Guber (GUBER, 2011, p. 45-46) quien habla de una triple reflexividad del investigador/a (como miembro de una sociedad o cultura; en tanto investigador/a con su perspectiva teórica y en tercer lugar la reflexividad del individuo o grupo que estudia), Mazzini problema­tiza sobre dichos conceptos a raíz de la investigación realizada en el Hospice San Camilo. La noción de reflexividad se comprende mejor con la de implicación, por eso la autora completa la opción hermenéutica hablando de implicación reflexiva, formula acuñada por el antropólogo suizo G. Althabe (ALTHABE-HERNANDEZ, 2005, p. 71-88).

Abstract: Indonesia's electricity consumption has increased every year. One way to overcome this problem is by utilizing renewable energy sources such as wind. Utilization of this energy uses wind turbines installed at locations that have met the requirements. Therefore, information on wind conditions in several layers is required by using radar products such as CAPPI, PPI, and HWIND which are processed using Rainbow 5 software and then interpreted in a daily wind speed graph. Data obtained from radar imagery of Syamsudin Noor Meteorological Station-Banjarmasin. And to determine the boundary conditions of the wind layer is determined according to the length of the turbine blades to calculate the minimum wind speed needed to drive the turbine blades. The results of this study show that wind conditions in layers of 100 to 600 meters tend to be the same, making it difficult to determine the maximum height of the wind layer and from 7 days of the observation sample, it is found that some average wind speeds per day are 4.076923 m / s, 4.777778 m / s, 4.393939 m / s, 0.75 m / s, 0.72973 m / s, 3.678571 m / s, and 1.4375 m / s, which are known to have not met the minimum wind speed requirements for wind farm (PLTB) to produce optimal energy.

Published: December 2019

Abstract: This paper reports the test results of a loudspeaker-based acoustic energy harvester with acoustic random noise sources from a motorcycle. The harvester consists of a quarter wavelength resonator and a subwoofer type loudspeaker with a nominal diameter of 6 inches. The motorcycle used in this experiment is 135 cc Bajaj Pulsar motorsport with modified exhaust from the GBS-Motosport Jakarta. The motor engine is operated at 3000 rpm, resulting in noise with a fluctuating Sound Pressure Level (SPL) in the range of (90-93) dB. Six variations of resonator lengths are used, those are 21 cm, 31 cm, 58 cm, 85 cm, 112 cm, and 139 cm. In this test, data of dominant frequency, SPL, and output rms voltage were taken for 15 minutes. The rms voltage is measured at 100 Ω load resistor. The results show that the 112 cm resonator produces the highest average rms electrical power, that is (0.21 ± 0.01) mW, which is obtained at frequency that fluctuates within (95-120) Hz. In addition, with random sound sources, SPL and its dominant frequency fluctuate greatly, so it will greatly affect the generated electric power. Further research is needed to enhance the output electrical power and anticipate the impact of frequency fluctuation which exists in random noise sources.

Abstrak: Paper ini memaparkan hasil pengujian alat pemanen energi akustik berbasis loudspeaker dengan sumber kebisingan acak dari mesin kendaraan bermotor. Alat pemanen energi akustik ini terdiri dari resonator seperempat panjang gelombang dan loudspeaker jenis subwoofer dengan diameter nominal 6 inci. Sumber kebisingan yang digunakan adalah motor Bajaj Pulsar 135 cc dengan knalpot modifikasi dari GBS-Motosport Jakarta. Mesin motor dioperasikan pada laju putaran tetap 3000 rpm, sehingga menghasilkan kebisingan dengan SPL (sound pressure level) yang berfluktuasi dalam interval (90-93) dB. Digunakan enam variasi panjang resonator, yaitu 21 cm, 31 cm, 58 cm, 85 cm, 112 cm, dan 139 cm. Dalam pengujian ini, data frekuensi dominan kebisingan, SPL kebisingan, dan tegangan keluaran alat pemanen energi akustik diambil selama 15 menit. Tegangan rms keluaran diukur pada resistor beban 100 Ω. Hasil eksperimen menunjukkan bahwa resonator dengan panjang 112 cm menghasilkan daya listrik rms rata-rata tertinggi yaitu sebesar (0,21 ± 0,01) mW, diperoleh pada frekuensi yang berfluktuasi antara 95 Hz sampai 120 Hz. Selain itu, hasil eksperimen ini menunjukkan bahwa dengan sumber bunyi acak, SPL kebisingan dan frekuensi dominannya sangat berfluktuasi, sehingga akan sangat berpengaruh terhadap daya listrik yang dihasilkan. Penelitian lebih lanjut diperlukan untuk meningkatkan daya listrik keluaran dan mengantisipasi dampak fluktuasi frekuensi sumber kebisingan acak.

Published: December 2019

Background: The outcomes of smoking have generated considerable clinical interest in recent years. Although people from different countries are more interested to the topic of quit smoking during the winter, few studies have tested this hypothesis. The current study aimed to quantify public interest in quit smoking via Google.Methods: We use Google Trends to obtain the Internet search query volume for terms relating to quit smoking for major northern and southern hemisphere countries in this research. Normally search volumes for the term “quit smoking + stop smoking + smoking cessation” were retrieved within the USA, the UK, Canada, Ireland, New Zealand and Australia from January 2004 to December 2018. Seasonal effects were investigated using cosinor analysis and seasonal decomposition of time series models.Results: Significant seasonal variation patterns in those search terms were revealed by cosinor analysis and demonstrated by the evidence from Google Trends analysis in the representative countries including the USA (pcos = 2.36×10-7), the UK (pcos < 2.00×10-16), Canada (pcos < 2.00×10-16), Ireland (pcos <2.00×10-16) ,Australia (pcos = 5.13×10-6) and New Zealand (pcos = 4.87×10-7). Time series plots emphasized the consistency of seasonal trends with peaks in winter / late autumn by repeating in nearly all years. The overall trend of search volumes, observed by dynamic series analysis, declined from 2004 to 2018.Conclusions: The preliminary evidence from Google Trends search tool showed a significant seasonal variation and decreasing trend for the RSV of quit smoking. Our novel findings in smoking cessation epidemiology need to be verified with further studies, and the mechanisms underlying these findings must be clarified.

Objective Dyslipidemia in the second trimester and associated gestational diabetes are increasing worldwide. Carnitine plays a key role in lipid metabolism. We aim to describe metabolic profiling in the second trimester based on carnitine related metabolomics in GDM and high risk pregnancy, and to find the potential risk factors in GDM and candidate metabolites for diagnosing GDM induced macrosomia.Methods We have randomly investigated 450 pregnant women and their neonates in this retrospective study and 56 (12.4%) GDM cases were diagnosed. We used LC-MS/MS performing metabolic profiling about 12 amino acids and 31 acylcarnitines (containing C0) to assess circulating metabolites concentration in different subgroup according maternal and newborn clinical characteristic. We also calculated the correlation coefficient between maternal and newborn. GDM potential metabolic risk factors were screened by PLS-DA. Multivariate regression analyses were used in identifying independent risk factors for GDM and macrosomia. Based on these carnitine-related factors, a nomogram for estimating macrosomia was developed.Results We found 14 AA (Ala, Arg, Met, BCAA, AAA) and AC (C0, C2, C3, C4DC+C5OH, C5, C16, C18, C18:1) were increased in Age > 35 group, BMI ≥ 30, weight gain > 20 kg group, using assistant reproductive technology group, but the level of C0, Gly were decreased. In fetal clinical data, we obtained AA and AC level in fetuses are higher than their mothers and the metabolic trend was similar with maternal result. PLS-DA showed 15 metabolism(C0, LEU+ILE+PRO-OH, Phe, C18, TYR, etc)play main roles in class separation of GDM. Multivariate analysis showed pre-pregnancy BMI, weight gain, LEU+ILE+PRO-OH, TYR, C0/acylcarnitine, C0, C3, C16, C18 are independent risk factors associated with GDM. Finally, we developed a nomogram predicting macrosomia based on carnitine-related metabolic variables.Conclusion Metabolomics was proved as a powerful tool in identifying the metabolic alteration during the second trimester. These metabolic risk factors in GDM may help understanding of the underlying biochemical pathology of GDM and help physician diagnosing macrosomia.

Nowadays, the creative industry contributes a lot to the economic growth. Reliable human resources support the organizational success. This study investigates the employees’ innovative behavior, which is assumed to be influenced by intellectual capital. This aspect consists of human capital, structural capital, and relational capital. This survey-based research studied the creative industry employees for four months in data collection and four months for analysis and interpretation of data processing results. This study used a quantitative method to answer the proposed hypothesis. The samples were 243 employees of the creative industry in Bandung, Cimahi, Bandung Regency, and West Bandung Regency, Indonesia. For processing the data and testing the hypotheses, the research employed the Partial Least Square-SEM. The results show that there is a compelling effect on human capital, structural capital, and relational capital on innovative behavior. The R-squared value of 0.46 indicates the overall impact. This research suggests some aspects that escalate the innovative behavior. The first aspect is skill enhancement, which leads to the raising of human capital. Next, providing the facilities and infrastructure for internet network connections builds the structural capital. Moreover, offering sources of raw materials needed by employees prompts the relational capital. By carrying out those efforts, the employees’ innovative behavior can increase optimally. Research on intellectual capital currently focuses on the performance of the company and dynamic capabilities. Currently, focus on processes of intellectual capital is still in an emerging stage.

Published: December 2019

The relationship between an aging workforce, higher retirement age, and youth unemployment has already been established in the available literature. However, the empirical research on the impact of an aging workforce, and higher retirement age on youth unemployment is limited, has conflicting results, has occurred mostly overseas, and has not considered the perceptions of young people who are about to enter the workforce. Hence, this paper aims to investigate the perceptions of the youth on the relationship between the aging workforce, higher retirement age, immigration policies, and youth unemployment. Structural equation modelling was used to analyze the responses of 183 business students. The findings establish that five relationships were supported out of seven hypothesized relationships. The key research finding reveal that immigration policies and higher retirement age are significantly related to youth unemployment. Lastly, the theoretical and managerial implications of the study were discussed, along with the limitations and recommendations for future research.

Published: December 2019

According to the results of epidemiological studies, the spread of periodontal tissue diseases has tendency to increase, despite recent decades’ significant achievements in dentistry. Studies of periodontal tissue diseases pathogenesis have found that oxygen-dependent production of reactive oxygen species (ROS) and antioxidant activity are involved in the pathogenic mechanism of the disease. ROS are highly toxic and can induce lipid peroxidation (LPO). Researchers have shown increased levels of LPO with generalized periodontitis (GP). "Noofen" is one of the drugs that normalizes the processes of LPO and shows positive effect in GP treatment. That is why in advanced complex treatment of generalized periodontitis of initial-I stage, we’ve used this pill.

The objective of the study was to analyze the efficiency of nootropic medicine "Noofen" usage in suggested initial-I stage of generalized periodontitis treatment, taking into account the dynamics of oral fluid prooxidant and antioxidant indicators among students with high level of emotional sensitivity.

Materials and methods. A study of 2nd year students (174) of Ivano-Frankivsk National Medical University were questioned in order to determine the level of individual emotional states (anxiety, frustration, aggression and rigidity) according to the method of H. Eysenck. Of those who have experienced increased and high level of emotional sensitivity to various stressors and situations, we have selected 50 students with initial-I stage of generalized periodontitis. To determine the efficiency of treatment, two groups were formed: observation (group I) and comparison (group II). Each group consisted of 25 individuals who were treated and monitored dynamically during the year. The condition of oral cavity prooxidant system was determined by the level of malondialdehyde (MDA) and diene conjugates (DC). To study the state of the antioxidant protection system, the activity of superoxide dismutase (SOD), glutathione-S-transferase (G-ST) and glutathione peroxidase (GPO) were determined. The advanced treatment, which included oral rinsing with "Octenisept" solution, dissolving of tablets "Lizak", intake of  medicine "Noofen" and vitamin-microelement complex "Vita-Supradin Active".

Conclusions. The results of the performed treatment indicate that the use of advanced therapy of GP is significantly more effective, confirmed by prooxidant-antioxidant system parameters of oral fluid in the long term, compared with traditional treatment.

Ergotherapist – is the youngest specialty in medical practice of Ukraine. The aim of higher medical educational institutions is to formulate logical, clinical thinking and effective assimilation of medical knowledge to be used by ergotherapists-practitioners. One of the main tasks of an ergotherapist is to restore the body’s functions that have been lost as a result of illness or injury, and to restore a person to a full social life (self-care, work, etc.). These specialists are working to restore the sensory and motor functions of the body, to develop new skills and abilities for the person to adapt to living in society. Achievement of the goal and performance of these tasks is impossible without knowledge of physiology, which provides the basis for the study of pathophysiology, pharmacology, cardiology, physiotherapy and other clinical disciplines. It improves the quality of study and helps to better acquire theoretical material, to master the skills of clinical physiology a competent approach in the organization of Physiology teaching.

Authors: Ostafiichuk Svitlana
Published: December 2019

The onset, duration of lactation and exclusive breastfeeding (BF) depend on maternal factors. Objective:  The aim of our study was to investigate the effect of pathological gestational weight gain (GWG) on subsequent lactation. Design: This was a prospective cohort study of 219 women, aged 18 to 43 years, who were enrolled at 9-11 weeks and were followed-up at 22-24, 37-39 weeks of pregnancy, and 1 year postpartum.  Anthropometry, body mass index, GWG were calculated. The percentage of body fat mass (% FM) was calculated on the basis of bioelectrical impedance analysis (BIA) using the “Diamant-aist” analyzer (St. Petersburg). The delayed onset of lactation (more than 72 hours), the duration of lactation, exclusive BF were interviewed. The results were statistically analyzed using statistical analysis package based on Microsoft Excel and Statistica 6.0 program pack (StatSoft Inc., USA). Results: The total BF and exclusive BF median durations were 29.7±10.1 (95% Cl 25.7-33.7) weeks and 22.2±6.2 (95% Cl 18.2-26.2) weeks, respectively. A negative association between the elevation of the %FM during pregnancy and the duration of BF (r= - 0.21, p=0.001; r= - 0.32, p<0.0001; r=- 0.47, p<0.0001, respectively in the first, second and third trimesters) was diagnosed. It has been proved that excessive GWG was significantly associated with shorter duration of lactation (p<0.05), with shorter duration of exclusive BF (OR 0.5; 95% Cl 0.2-0.9, p=0.03), with increased chances of discontinuing BF before 6 month postpartum (OR 2.2; 95% Cl 1.0-4.5, p=0.04), and delayed onset of lactation (OR 2.1; 95% Cl 1.1-4.1, p=0.04) compared with the recommended GWG women. Conclusion: Informing the pregnant women about the negative effect of pathological GWG on subsequent lactation, regular assessing the dynamics of weight gain during pregnancy, and taking measures to prevent overweight and obesity in the postpartum period should be an important focus of antenatal care.
Peculiarities of Metabolism of Rats with Fructose-induced Insulin Resistance Against the Background of Congenital and Acquired Iodine Deficiency
Authors: Stetseviat Vasyl
Published: December 2019

Animals following a high-fructose diet during eight weeks, have experienced changes in metabolism and the signs of insulin resistance have developed. Under such conditions, moderate hyperglycemia, hyperinsulinemia, hyperuricemia, an increase of the level of glycosylated hemoglobin in whole blood were observed. The significant role of the HOMA-IR index, as an early marker of carbohydrate metabolism disorders at the stage of pre-diabetes, has been confirmed. In experimental animals against the background of the high-fructose diet, the changes in the lipid spectrum of the blood were revealed: an increase of the total cholesterol level, low-density lipoproteins, triglycerides against the background of a high-density lipoproteins decrease. These disorders and a significant increase of the atherogenicity reflect the development of secondary dyslipidemia. In this case, the disorders of carbohydrate metabolism were combined with the degree of dyslipidemia. Males were found to have at increased risk of development the insulin resistance and comorbid pathology. Iodine deficiency, especially of congenital nature, is an aggravating factor of metabolic disorders. The obtained data can serve as a basis for extend of preventive measures and identification of the priority treatment schemes for type 2 diabetes mellitus in residents of endemic regions.
The Use of the Test for Oral Muscular Coordination Ability to Increase the Level of Adaptive Capacity of Oral Cavity Organs to Prosthodontic Treatment of Patients with Completely Absent Dentition
Authors: Sarapuk Volodymyr
Published: December 2019

Increase in the level of adaptive capacity of oral cavity organs to the prosthodontic treatment of patients with completely absent dentition is one of the urgent problems of modern dentistry. In order to increase the level of adaptability to complete removable laminar dentures, a set of standard samples according to H. Landt was used to test the ability for precise coordination of masticatory muscles – the MA-test (Muscular-Ability) as a means of a group of muscles stimulation providing precise coordination of masticatory muscles. This adaptation process was called MA-stimulation. The level of adaptive capacity of the oral cavity organs was studied using oral stereognosis. The criteria for oral stereognosis assessment included the average time of one sample determination (sec) and the correctness of the samples determination (%). In order to achieve the objective, we conducted a study of tactile sensitivity in the oral cavity using oral stereognosis in 90 patients with completely absent dentition who applied for the prosthodontic retreatment. The patients’ age ranged from 45 to 89 years. The patients were divided into two groups. Group I included 30 patients who underwent the prosthodontic treatment without preliminary MA-stimulation. Group II included 60 patients who underwent MA-stimulation for 14 days before the prosthodontic treatment.

According to the results of oral stereognosis in Group II of patients, the average time of one sample determination after fourteen days of MA-stimulation decreased by 24.5% (p˂0.05) and the index of correctness of the samples determination increased by 32.0% (р˂0.001); the average time of one sample determination decreased by another 19.3% in 1 month after the prosthodontic treatment, and it decreased by 17.4% (р˂0.05) in 3 months after the prosthodontic treatment; the index of the correctness of the samples determination increased by 17.5% (p˂0.001) and 10.5% (p˂0.01) respectively in 1 and 3 months after the prosthodontic treatment.

Oral stereognosis indices changed significantly only in 1 month after the prosthodontic treatment in Group I of patients who did not undergo MA-stimulation: the average time of one sample determination decreased only by 14.7% (p˂0.05), and the index of correctness of the samples determination increased only by 24.5 (p˂0.05).

According to the results of the research, MA-stimulation is advisable to be included into the prosthodontic treatment of the patients with completely absent dentition as a means of increasing the adaptive capacity of the oral organs.
