Wiek emerytalny w Polsce na tle państw Unii Europejskiej. Konsekwencje utrzymywania niskiego minimalnego wieku emerytalnego
Authors: Russel Piotr 
Published: December 2023

Celem artykułu jest zaprezentowanie występujących w całej Unii Europejskiej tendencji w zakresie kształtowania minimalnego wieku emerytalnego, jak również najważniejszych implikacji wynikających z utrzymywania niskiego wieku emerytalnego w Polsce. Przeprowadzona analiza powinna umożliwić weryfikację hipotezy, iż w dłuższej perspektywie czasowej niezasadne jest utrzymywanie tak niskiego wieku emerytalnego, zwłaszcza dla kobiet. Jednocześnie pozytywne zweryfikowanie tak postawionej hipotezy powinno umożliwić sformułowanie następującej rekomendacji – należy podjąć działania, których celem będzie uzyskanie konsensusu co do potrzeby stopniowego zrównania wieku emerytalnego kobiet i mężczyzn na poziomie 65 lat. Jest to bowiem warunek konieczny skuteczności wdrożenia proponowanej rekomendacji. W artykule zaproponowano również autorską koncepcję uelastycznienia wieku emerytalnego, która mogłaby zmniejszyć prawdopodobny opór społeczny wobec proponowanych zmian.
ТОРГІВЛЯ ЛЮДЬМИ: СУЧАСНИЙ СТАН, ДИНАМІКА ТА НАПРЯМИ ПРОТИДІЇ
Authors: Сперкач Н. А. 
Published: December 2023

У статті досліджується сучасний стан, динаміка та напрями протидії торгівлі людьми. Визначається, що в Україні торгівля людьми з початком війни ще більше загострилась, адже значна кількість людей з країни примусово вивезена країною-агресором на територію росії та білорусі, також досить складна економічна ситуація, корупція, високий рівень безробіття, поширення зовнішньої трудової міграції, диспропорції розвитку ринку праці, поширеність шахрайських схем вербування громадян, активізація діяльності міжнародних злочинних угруповань, недосконалість законодавства, правова необізнаність населення та інші фактори ризику призводять до потрапляння в ситуацію торгівлі людьми.
Особливої актуальності проблема торгівлі людьми набула в контексті повномасштабної війни, адже вона стала одним із тяжчих наслідків для українського суспільства, враховуючи той факт, що мільйони людей, які були змушені евакуюватися чи за кордон, чи просто на інші території, або ті, яких примусово вивезли на територію країни-агресора, стали потенційними жертвами з високим рівнем віктимності. Саме, тому у статті досліджено напрями координації дій щодо протидії торгівлі людьми на всіх рівнях, комплексного системного підходу та швидкого реагування на потенційну загрозу чи фактичну ситуацію, що може забезпечити належний рівень соціального захисту населення та вберегти від можливих ризиків торгівлі людьми.
У статті автором наведено статистичні дані щодо зареєстрованих кримінальних правопорушень у сфері торгівлі людьми, кількості осіб, що вчинили це правопорушення, наводиться загальна кримінологічна характеристика торгівлі людьми в Україні за останні роки, а також опрацьовані статистичні дані Національної соціальної сервіс­ної служби України щодо осіб, яким надано статус постраждалих від торгівлі людьми.
Також досліджено напрями співпраці України з Міжнародною організацією міграції та іншими партнерами щодо превентивних заходів для протидії торгівлі людьми, а також координаційних дій Міграційної поліції з європейськими партнерами щодо створення європейської платформи з обміну інформації про торгівлю людьми.
На основі проведеного наукового дослідження проблематики торгівлі людьми виокремлені конкретні дієві напрями протидії цього кримінального правопорушення. Зазначено, що на рівні держави, міжнародних організацій та громадянського суспільства повинна бути повна та дієва консолідація зусиль як органів державної влади, так і органів місцевого самоврядування, а також громадських організацій та громадян щодо запобігання торгівлі людьми. Відмічено, що досить важливим і першочерговим завданням є забезпечення ефективної, належної, актуальної протидії таким кримінальним правопорушенням шляхом спільного реагування та скоордино­ваних дій усіх відповідних суб’єктів, адже свобода людини є однією з головних цінностей сучасного цивілізованого суспільства, а забезпечення її недоторканності – однією з основних функцій держави.

A novel optimal formula of nickel extraction: arsenic removal from niccolite by controlling arsenic-containing phases
Authors: Tang Xiaowei , He Yuehui 
Published: December 2023

Objective: Niccolite, a rare nickel arsenide mineral, has emerged as a promising source for nickel extraction. However, its processing is limited and often associated with toxicity concerns. This study aims to search for efficient separation of arsenic during the roasting process of niccolite.Methods: The arsenic-containing phase was optimized through changing the contents of oxygen, additive S, and additive FeS in the system to achieve efficient separation of arsenic during the roasting process of niccolite. Thermodynamic analysis was performed using the equilibrium composition module with HSC Chemistry.Results: The thermodynamic results showed that in direct roasting, the product contained ferric arsenate which immobilized arsenic in the solid phase, increasing the difficulty in separation. In the presence of sulfur, the arsenic may escape completely in the form of gas (As2O3, As4O4, As4O6). The use of FeS as the reductant significantly reduced the residual arsenic content.Conclusion: The FeS reduction in roasting process is an optimal strategy for arsenic removal from niccolite. This provides a novel technique for nickel extraction in industry.

ObjectiveTo evaluate the outcomes of thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (TBAD) with aberrant right subclavian artery (ARSA).MethodsA retrospective analysis was conducted on patients with TBAD and ARSA who underwent TEVAR between the period of January 2017 and December 2022. Patient demographics, computed tomography angiography (CTA) measurements, surgical procedures, and postoperative outcomes were reviewed.ResultsA total of 9 patients (6 males and 3 females) were included in the study. 4 ARSA were reconstructed, 3 by periscope technique and 1 by in vitro fenestration technique. 3 left subclavian arteries (LSA) were reconstructed, 1 by the chimney technique and 2 by the single-branched stent technique. 2 patients underwent reconstruction of both ARSA and LSA. The overall technical success rate was 100%, with no occurrences of stroke, paraplegia, or mortality within 30 days. 1 patient experienced immediate type Ia endoleak, which resolved after 3 months. 1 patient developed weakness in the right upper limb, while 1 patient presented mild subclavian steal syndrome (SSS); both cases showed recovery during follow-up. The average follow-up duration was 35.6 ± 11.1 months, during which no reinterventions, deaths, or strokes were observed.ConclusionOur limited experience involving 9 patients demonstrates that early and mid-term outcomes of TEVAR for the treatment of TBAD with ARSA are satisfactory.

Published: December 2023

BackgroundBrain-computer interface (BCI) systems based on motor imagery (MI) have been widely used in neurorehabilitation. Feature extraction applied by the common spatial pattern (CSP) is very popular in MI classification. The effectiveness of CSP is highly affected by the frequency band and time window of electroencephalogram (EEG) segments and channels selected.ObjectiveIn this study, the multi-domain feature joint optimization (MDFJO) based on the multi-view learning method is proposed, which aims to select the discriminative features enhancing the classification performance.MethodThe channel patterns are divided using the Fisher discriminant criterion (FDC). Furthermore, the raw EEG is intercepted for multiple sub-bands and time interval signals. The high-dimensional features are constructed by extracting features from CSP on each EEG segment. Specifically, the multi-view learning method is used to select the optimal features, and the proposed feature sparsification strategy on the time level is proposed to further refine the optimal features.ResultsTwo public EEG datasets are employed to validate the proposed MDFJO method. The average classification accuracy of the MDFJO in Data 1 and Data 2 is 88.29 and 87.21%, respectively. The classification result of MDFJO was significantly better than MSO (p &lt; 0.05), FBCSP32 (p &lt; 0.01), and other competing methods (p &lt; 0.001).ConclusionCompared with the CSP, sparse filter band common spatial pattern (SFBCSP), and filter bank common spatial pattern (FBCSP) methods with channel numbers 16, 32 and all channels as well as MSO, the MDFJO significantly improves the test accuracy. The feature sparsification strategy proposed in this article can effectively enhance classification accuracy. The proposed method could improve the practicability and effectiveness of the BCI system.

IntroductionWith the climate warming, the occurrence of freezing events is projected to increase in late spring and early autumn in the Northern Hemisphere. Observation of morphological traits showed that Cycas panzhihuaensis was more tolerant to unexpected freezing stress than C. bifida. Energy balance is crucial for plant tolerance to stress. Here, we aimed to determine whether the different responses of the two species to the unpredicted freezing stress were associated with the metabolism of energy and related substances.MethodsThe effects of unexpected freezing temperatures on C. panzhihuaensis and C. bifida were studied by measuring chlorophyll fluorescence parameters, energy charge and the profile of nonstructural carbohydrates (NSC) and lipids.ResultsC. panzhihuaensis exhibited higher stability of photosynthetic machinery than C. bifida under unpredicted freezing events. Significant interaction between species and treatments were observed in the energy charge, the level of NSC and its most components and the amount of most lipid categories and lipid classes. The decrease of soluble sugar and the increase of neutral glycerolipids at the early freezing stage, the accumulation of membrane glycerolipids at the late freezing stage and the continuous decrease of energy charge during the freezing period were the characteristics of C. panzhihuaensis responding to unexpected freezing stress. The degradation of membrane glycerolipids and the continuous decrease of soluble sugar during the freezing period and the accumulation of neutral glycerolipids and energy charge at the late freezing stage represented the characteristics of C. bifida responses.DiscussionThe different freezing sensitivity between C. panzhihuaensis and C. bifida might be associated with the differential patterns of the metabolism of energy, NSC and lipids. C. panzhihuaensis possesses the potential to be introduced to the areas of higher latitudes and altitudes.

IntroductionWork stress is a frequent factor in the development of depression. However, not only workplace environment, but also personal attitudes may affect stress experience. The aim of this study was to investigate the change sensitivity of occupational attitudes in psychosomatic inpatients and assess the relationship of changes to depressive symptom reduction.MethodsThe data set encompassed N = 1708 inpatients from two German psychosomatic rehabilitation clinics at admission and discharge. Responsivity of AVEM measures was evaluated by Bonferroni-corrected t-tests and Cohen’s dz effect sizes for paired samples. The relation of occupational behavior and experience patterns and depressive symptoms as assessed by the BDI-II questionnaire was calculated by Pearson correlation analysis of pre-post differential values.ResultsChanges in work attitudes were found on eight out of eleven AVEM subscales (Padj ≤ 0.001, Cohen’s dz = −0.45 to 0.43) and all AVEM coping styles. Most patients (57.4%) were classified to have a Burnout occupational coping style at admission. Changes following rehabilitation were most frequently observed from Burnout to Sparing coping styles (8.3%). Small to moderate associations between changes in occupational attitudes and depressive symptom reduction were found for all subscales (r = −0.39 to 0.25) except work ambition, and for occupational coping styles Burnout (r = 0.19), Sparing (r = −0.18) and Healthy (r = −0.10), but not Ambitious.DiscussionThe data support responsivity of occupational behavior and experience patterns within a psychosomatic rehabilitation setting. Correlations with depressive symptom reduction suggest that occupational attitudes are related but separate treatment targets.

IntroductionOver the last decade, yields and profitability of crops on agricultural lands in the Kyzylkum irrigation massif in the south of Kazakhstan, as well as soil fertility, have been decreasing. The Kyzylkum irrigation basin, located in the Syrdarya River basin, is affected by various factors such as agronomic practices, reclamation factors, and human activities including tourism. This study aims to monitor the yields of cotton and alfalfa in alfalfa-cotton crop rotations in the Kyzylkum irrigation massif, assess soil fertility after alfalfa and cotton cultivation under production conditions, and evaluate the profitability of water consumption.MethodsThe research methodology involved experimental and observational studies conducted on a nine-pole alfalfa-cotton crop rotation area in the Kyzylkum basin within the Syrdarya river basin. The study was conducted on three farms: Didar, Toishy, and Ali-Myrza. Productivity, soil fertility after crop cultivation, and profitability of water consumption were determined through these studies.ResultsThe study found that the Ali-Myrza farm experienced a 21% increase in cotton yield, a 24% increase in alfalfa yield, a 36% increase in profit from crop rotation, a 34% increase in profitability, and a 5-6% increase in water consumption. After alfalfa rotation, the Ali-Myrza farm recorded the highest cotton yield at 3.5 t/ha and a profit of 1,316 euros/ha. However, in the following year, cotton yields decreased to 2.52 t/ha, and profits dropped to 576 euro/ha. The first year of alfalfa cultivation resulted in a yield of 10 t/ha and a profit of 462 euro/ha, which increased to 14 t/ha and 967 euro/ha in the subsequent year. Soil analysis revealed that after two years of growing alfalfa in a six-pole rotation, the root mass in the top 20 cm of soil reached 8.89 t/ha. In contrast, rotations with seven (Toishy) and nine (Didar) crops resulted in lower root masses of 4.68 t/ha and 3.47 t/ha, respectively. The corresponding humus content was 1.65%, 1.40%, and 1.1%, respectively.DiscussionComparing the seven and nine-pole rotations of alfalfa and cotton, the six-pole rotation demonstrated significant improvements in soil fertility (30-40% increase), cotton yield (18-23% increase), alfalfa yield (20-28% increase), and water consumption (5-6% increase). These findings confirm the effectiveness of the alfalfa-cotton rotation method in enhancing soil fertility, productivity, water efficiency, and grey soil productivity in Kyzylkum irrigated fields. The results obtained from this study can be applied in cotton farms in South Kazakhstan that use nine-layer cotton and alfalfa rotations. Furthermore, the findings have implications for cotton cultivation in any country worldwide.

Aim. The aim of the study was to establish the changes in nitric oxide production and metabolism in rat heart during combined influence of organism stimulation with bacterial lipopolysaccharide (LPS) and modeling of metabolic syndrome (MetS).
Materials and methods. The study was conducted on 24 mature male Wistar rats weighing 200–260 g. Experiment lasted 60 days. The animals were divided into 4 groups of 6 animals each: control group, MetS group, LPS stimulation group, LPS + MetS group. MetS was reproduced by using a 20 % fructose solution as the only source of drinking water. LPS of Salmonella typhi was administered at a dose of 0.4 μg/kg intraperitoneally. Animals from LPS + MetS group received a 20 % fructose solution as the only source of drinking water and were administered LPS. In 10 % tissue homogenate of rat heart we studied: total activity of NO-synthases (NOS), activity of constitutive (cNOS) and inducible (iNOS) isoforms, activity of nitrate (NaR) and nitrite (NiR) reductases, concentration of peroxynitrites (ONOO-), nitrites, nitrosothiols and hydrogen sulfide.
Results. Combination of MetS and stimulation of organism with LPS led to increase in total NOS activity by 32.72 % compared to control group. Activity of cNOS did not change compared to control group. Activity of iNOS increased by 33.76 %. Arginase activity decreased by 23.53 %. NaR activity and NiR activity were increased by 86.67 % and by 149.29 %, respectively. Combination of MetS and stimulation of organism with LPS led to decrease in nitrite and nitrosothiols concentration by 38.73 % and by 54.79 %, respectively. Under these conditions concentration of ONOOelevated by 398.0 % compared to control group. Concentration of H S decreased by 27.56 %.
Conclusions. Combination of metabolic syndrome and stimulation of organism with bacterial lipopolysaccharide leads to prevalence of peroxynitrite formation during increased nitric oxide production NO-synthase-dependent and nitrate-nitrite-NO pathways in rat heart.

Published: December 2023

The use of cleaner leather processing technologies is of great interest today due to the global trends favoring environmentally friendly manufacturing. Modernization and implementation of new technologies, like enzyme-driven catalysis instead of conventional inorganic catalysis, can improve the quality and reduce the cost of leather manufacturing while making the leather more environmentally sustainable. The use of enzymes in pre-tanning operations is a well-known technology. However, a holistic view of the effect of enzymes at various stages of leather processing is limited. We attempt to bridge this gap by studying the influence of enzymes on the characteristics of crust leather at multiple locations of leather processing. Trypsin was used to assess the enzymatic action on delimed pelts, while pepsin was used to evaluate the impact of enzyme treatment on a pickled pelt that was later chrome tanned.
Similarly, papain was used to study enzymatic activity on neutralized, chrome-tanned leather. The selection of enzymes for three different materials was guided by the optimal activity behavior of the enzymes. It is observed that the physical strength characteristics of the enzyme-treated leathers show minor differences. Hence, this study aims to explore the unconventional application of enzymes at various stages of leather processing.
