Authors: Boyoukliev Ivaylo V. , Kulina Hristina N. , Gocheva-Ilieva Snezhana G.
Published: November 2022

The aim of the study is to obtain an accurate result from forecasting the EUR/USD exchange rate. To this end, high-performance machine learning models using CART Ensembles and Bagging method have been developed. Key macroeconomic indicators have been also examined including inflation in Europe and the United States, the index of unemployment in Europe and the United States, and more. Official monthly data in the period from December 1998 to December 2021 have been studied. A careful analysis of the macroeconomic time series has shown that their lagged variables are suitable for model’s predictors. CART Ensembles and Bagging predictive models having been built, explaining up to 98.8% of the data with MAPE of 1%. The degree of influence of the considered macroeconomic indicators on the EUR/USD rate has been established. The models have been used for forecasting one-month-ahead. The proposed approach could find a practical application in professional trading, budgeting and currency risk hedging.
Inflation and Inflation Differentials in Core Eurozone Countries
Authors: Popović Svetlana , Janković Irena , Lukić Velimir
Published: November 2022

The paper analyzes the convergence of inflation rates in the group of more developed members of the Eurozone (core countries). What are the characteristics and is the inflation process in these countries sufficiently homogeneous? Are the analysed inflation rates converging, so that there is an indication that these countries tend to form the optimal currency area. We used a unit root test to check the stationarity of a series of average inflationary differentials. They are calculated as the difference between inflation rate in a given country and the inflation rate in EMU. If the convergence process took place, the inflationary differentials will decrease and tend to zero. The variance of differentials will also decrease, so the series of average inflationary differentials will be stationary. The analysis showed that there is a unit root in the series, thus it is not stationary, and we cannot conclude that the process of convergence of inflation rates in the core countries happened. The paper also analyzes the autocorrelation functions of inflation rates, to determine the persistence of inflation, i.e. how long it takes for the shock that caused the inflation growth of 1%, to die off. The values of the first autocorrelation coefficients are high, while the next ones fall slowly, so it takes a long time for the impact of the inflation shock to disappear. In addition, the correlograms of inflation rates are quite heterogeneous, which indicates that inflationary processes differ.
The Significance of ICT Services for the Balance of Payments in the Republic of Serbia
Authors: Kalinović Milan , Todorović Miloš , Marković Ivan
Published: November 2022

The balance of payments deficit is the problem faced by numerous countries. To solve the problem of the balance of payment deficit, the creators of economic policy try to stimulate the sectors that secure the largest inflow of foreign currencies and have a beneficial impact on the reduction of deficit. The international trade in informational, computer and telecommunication services records enormously high growth rates in the 21st century. The specificity of ICT sector opens a perspective even to less developed economies to take part more significantly in the exports, which hold a large percentage of a value-added. The goal of this paper is to determine the significance of ICT services for the balance of trade and the current account adjustment, as well as the contribution to generating the surplus of the total balance of services. In the case of the Republic of Serbia, the surplus of ICT sector covers almost one-fifth of the balance of trade deficit, almost one-third of the current account deficit, while every fourth dollar achieved by the services’ exports is achieved by the exports of ICT services. If the same trend of ICT sector’s growth continues, the predictions say that the surplus of this sector will be enlarged by almost 60% till the year of 2024, when compared to the level in 2020. Finally, potentially the most significant advantage, which ICT sector brings with itself, is the reduced brain drain, which is the most destructive consequence brought to the less developed countries by the liberalization of workforce’s movement.
Specific Aspects of the Economic Policy in the Conditions of the Covid-19 Pandemic
Authors: Milošević Danijel , Marjanović Vladislav
Published: November 2022

Covid-19 has hit the world intensely. From the medical point of view it seems that we have found the way to fight it, and the new task is to recover the economies. First of all, we need to assess the impact and specify the industries that suffered the most in order to create support packages. It is, as well, crutial to define the engines that are still able to drive the economies towards the recovery. The main aim for economic policy makers should be to flatten the curve of the recession that will occur, no doubts. During this process, it is of highest importance to balance the extent of the support government will provide for the economy. Namely, what we want is to lower the intensity of the impact by prolonging the effects of the crisis, however without increasing the debt too high. Specific action plans have to be created individually, with regards to particular economies and their determinants. For that reason, there is no pattern that policy makers could follow.

Having in mind that Serbian public debt is already high, it is essential to carefully design the support packages, without jeopardizing future income.
The Politics of Physiognomic Perception
Authors: Verstegen Ian
Published: November 2022

This article stages a confrontation between latent nominalist attitudes about inherent expression in perception—physiognomy—and new affective modes. In a classic analysis, Gombrich warned of the lack of veridicality of physiognomic perception, a sentiment endorsed by postmodern theories. At the same time, affect theory affirms a level of directly available intensities. Using the example of Rudolf Arnheim, it can be seen that the two are really specular opposites of each other, each merely valorizing different poles of the affect-cognition scale. Arnheim’s Gestalt theory shows how immediate percepts can have a generic structure, which is differentiated with further acquaintance. Arnheim, however, shows how perception can never account for all the power of expressive seeing. Perception and cognition is always embedded in a social matrix. Using an example of racist antisemitic propaganda used by Gombrich, the political implications of Arnheim’s position are demonstrated.
Does the early release of retirement savings prolong labor market participation for workers approaching retirement? Evidence from Australia's “Transition to Retirement Income Streams” program
Authors: Carter Andrew Dudley
Published: November 2022

Australia's “Transition to Retirement Income Streams” (TRIS) program aims to prolong labor force participation for older workers (aged 55–65 years) by offering early access to a worker's compulsory retirement savings (superannuation). Using a difference-in-differences design, our results suggest a small labor supply response, which increases after the program's initial years. The size of the effects appears to be consistent with the program adoption profile, which was low initially. For this reason, our estimates should be viewed as a lower bound for the true effects. We find that individuals with higher incomes are more likely to adopt TRIS. At least half of the program participants appear to be using strategies to minimize tax, a behavioral response that seems at odds with the program's intent.
Operations with Excise Goods, Sanctions Vs. Misdemeanors
Authors: Boiţă Marius , Dumiter Florin Cornel , Ajtay Eduard , Milutin Ionela Mihaela
Published: November 2022

The present work analyzes the trade with excise goods and is addressed to traders of excise goods, entrepreneurs, as well as practitioners in the financial and accounting field, who, in the transactions made with excise goods, may violate the relevant legislation, and may be sanctioned as a contravention, or as the case may be, criminal. Given that the sale of excisable products represents a high fiscal risk, the fiscal authorities have introduced a series of laws, acts, and provisions, including the regulation to use electronic invoicing using the SAF-T (Standard Audit File for Taxation) reporting system, E-invoice or Statement 406 in all situations of trading (excisable) products with high fiscal risk starting from July 2022, by issuing electronic invoices, which bring changes regarding the authorization, movement of excisable products and the procedure for carrying out activities with excisable products, to reduce tax evasion, monitoring, compliance and sanctioning of those who do not comply with excise legislation. In the content of the work, through a case study, we will describe a case regarding non-compliance with the legislation by an entity, how it was sanctioned, and the applicable legislation for this act. The present article considers the current implacable reality, which is, that with the appearance of new rules or obstacles in combating fraud, the methods of fraud have also diversified.
Influence of Inheritance Tax on the Size of Shadow Economy and the Volume of Tax Evasion
Authors: Linseis Philippe
Published: November 2022

The objective of the paper is to investigate the influence of the inheritance tax on the amount of tax evasion in different countries. The inheritance tax is among the most unpopular taxes. It is assumed, that unpopular taxes, such as the inheritance tax, have a measurable influence on the amount of tax evasion. Countries that levy inheritance taxes and countries which don’t levy inheritance taxes are compared in their success in fighting the shadow economy over a longer period (1991 – 2017). For that, data from Medina and Schneider from 2019 about the development of the shadow economy and from the OECD about the inheritance tax revenue is used. The approach is, to find dependencies between the inheritance tax revenue and the size of the shadow economy. The results show, that countries which abolished the inheritance tax, are not anymore that successful in fighting tax evasion than they were before. There is also evidence, that countries with a relatively high inheritance tax revenue are not able to fight tax evasion to the same extent, as countries that levy relatively low inheritance taxes. Therefore, in terms of reducing tax evasion, it is not recommended to abolish already introduced inheritance taxes, but rather to continue levying a moderate inheritance tax.
The Reorganization of Budgetary Obligations. General Considerations About this Juridical Institution
Authors: Oneţ Cristina
Published: November 2022

In 2019, the Romanian legislator regulated for the first time, in the content of O.G. no. 6/2019, the legal institution of the restructuring of budgetary claims on the establishment of fiscal facilities. After that, a series of successive normative acts were adopted, meant to prolong the effects of the initial normative act, but also to bring new and necessary clarifications to the content of this legal institution and the procedure for its development from the moment of initiation until the final extinguishment of its effects on the public budget and the patrimony of the involved budgetary debtor. As we have already shown in the content of the present paper, the analysis of the way in which the restructuring of budgetary claims is regulated has allowed us to draw a series of conclusions concerning this legal institution: a. the restructuring of the budgetary claims is a relatively new legal institution that has been adopted through a normative act other than the Fiscal Procedure Code, which it does not, directly and explicitly, amend or supplement, but indirectly by the fact that it can interfere in the conduct of the fiscal procedure, as well as by the fact that it refers to fiscal law institutions regulated by the Fiscal Procedure Code and which thus bears substantial changes; b. the restructuring of the budgetary claims is essentially different from the other forms of financial support established by the provisions of the Fiscal Procedure Code and in particular from the payment facilities designed to provide the budgetary debtor with a grace period in order to obtain the funds necessary to extinguish by payment his obligations to the public budgets. It is also different from the cancellation of tax claims established by the Fiscal Procedure Code because it becomes applicable when the collection of tax receivables becomes useless, inefficient, or impossible. c. although it differs from the rescheduling and adjournment of payment, or the cancellation of tax claims, however, in regulating the restructuring of budgetary claims, the legislator appeals to them themselves, in the form in which they were established in the provisions of the Fiscal Procedure Code.d. the local tax authorities have the right to decide (they are not obliged by law to do so) if they use this legal institution, in the process of collecting the debts due to the budgets they manage;e. in terms of content, the restructuring refers to any kind of budgetary claim (due to the general consolidated budget), in connection with which enforceable titles have also been issued (i.e. the claim has become certain and demandable).
Women as Leaders of Organising Running Events Teams
Authors: Waśkowski Zygmunt
Published: November 2022

Running is one of the most popular methods of spending time in active form in the world. The vast majority of managers who organise runs are former or actual runners. It is interesting to note that more men are leaders of teams which organise running events, while women as leaders are very rare. The main purpose of the research was to find the influence of sex of leader on the style of leadership, decision process and atmosphere in team. The author of this article conducted quality research using individual deep interview method. Data were collected from 23 individual deep interviews with managers of big running events organised in Poland, and 14 with the members of their teams. Currently, effective leaders should have competences different than what were prevalent 20–30 years ago. More important is, for example, emotional intelligence, empathy and interpersonal skills. Organisations operating in the amateur sport market have to build networking with many partners from the public and business sector, so leaders should concentrate on cooperating with stakeholders representing different expectations. Competences that women possess over men are required. Unlike other industries, in the running market there are very few women as leaders. Several reasons abound for this, some of which include economic and sociological grounds.

Authors: Rutkowski Ireneusz P.
Published: November 2022

This paper attempts to present a method for determining the level of goal achievement corresponding to a marketing strategy formulated for a new product launched in a competitive market. The research method used in this paper is a literature review in the area of new product development (NPD) and marketing strategy. The obtained scientific results indicate the importance of measurement of the effects of a new product strategy and provide various new metrics in this field. In practice, the author proposes useful indicators to measure the effects of a new product strategy in competitive markets. Given the economic and marketing implications of the study, its originality concerns the results that provide the basis for the improvement of company’s efforts in effect measurement of a new product strategy and also marketing strategy in competitive markets. The present paper contains an overview of scientific works about new product competitiveness, and also proposes a modification of the method used to measure new product competitiveness on the marketplace. The research contribution to marketing sciences primarily includes the formulation of a set of real rates to measure success or fail rate of a new product strategy in a competitive market. The novelty of the research lies in the approach used to obtain quantitative parameters for evaluation of market competitiveness of a new product in various industries.
Interface of Organisational Ageing and Organisational Ecology Theory
Authors: Vargas-Hernández José G. , Rakowska Joanna , Vargas-González M. C. Omar C.
Published: November 2022

The study aimed to conclude on the up-to-date state of the organisational ecology theory concerning relations between organisational ageing and organisational ecology, enhanced by social and ecological systems and ecological management. The applied method included analytical and reflective concluding, based on the synthesis of findings from a critical literature review. It was concluded that: (i) organisational ageing generates some of the most important consequences in organisational ecology; however, there is still no consensus on what kind of consequences prevail; (ii) at population level, the adaptation of organisational structures occurs with the replacement of old organisations that fail to adapt by the new ones; (iii) under the prevalent backdrop of radical structural and strategic changes, individual organisations are subject to inertial forces and thus are confronted with limitations to their success; (iv) ageing has positive consequences for innovative activities of older companies; and (v) the higher the density and concentration of industry, the higher the rates of founding firms and the lower the rates of mortality.
Organising Religious Resistance: Contingent Procedures, Material Religion and early Soviet Repression against Religion
Authors: Lisnic Dumitru
Published: November 2022

This study deals with the emergence of organised forms of resistance to the Bolshevik policies of secularisation, and the role that documents introduced into the religious landscape in the 1920s by the Soviet regime played in it. Integral to the Bolshevik campaign of eliminating religions, the mandatory registration of religious communities transposed into the religious landscape the organisational forms and techniques of the production of documents characteristic of bureaucracy, which enhanced the capability of believers to pose an organised resistance to antireligious policies. This paper measures the consequence of these documents and bureaucratic practices, their role in the consolidation of religious organisations and the creation of antagonism between parishioners and state officials. My study is centred on the case of the Orthodox Church of our Lady of Kazan from Cioburciu (Moldavian Region of Soviet Ukraine), the construction of which was at the heart of the confrontation of Orthodox believers from this settlement with the Soviet authorities.
Sectarian Traitors? Factors that Supported and Thwarted Conversion among Baptist Communities under Two Regimes in the Early Twentieth Century
Authors: Wanner Catherine
Published: November 2022

In the late Russian Empire, and later Soviet Ukraine, aspects of Baptist doctrine and communal life earned Baptists the suspicion of their Orthodox neighbors and of state and ecclesiastical authorities. Depending on the dynamics of change, the perceived foreign origins of Baptism, their advocacy of pacificism, and their understandings of morality and transformation were either viewed favorably and allowed these communities to grow through conversion. Or, the same attributes earned Baptists the wrath of state and Church authorities and led to repression. This article analyzes how and why the threat posed by a minority faith group changed over time and how these communities adapted.
The Heterodoxy of Female Mysticism Before and During State Socialism: Vasilica Barbu and the Vladimireşti Convent
Authors: Clark Roland
Published: November 2022

Vasilica Barbu, also known as Mother Veronica, a seer and then an abbess in mid-twentieth century Romania, had visions of Jesus, Mary, and a variety of angels and saints, beginning in 1937. Supported by her parish priest and other local believers, she published an account of her visions and founded a convent for adolescent girls. The Vladimireşti convent proved to be very successful, but the Securitate (secret police) decided to close it down on the grounds that it was harbouring fascist fugitives. A close reading of how Barbu navigated the challenges of poverty, patriarchy, and the rise of state socialism reveals not only a story of incredible tenacity in the face of adversity but also how fundamentally religious values changed following the Second World War. Whereas in the late 1930s Barbu’s visions enabled her to bring together a strong community of supporters and to attract the attention of the most powerful men in the country, in the early 1950s both Church leaders and the Securitate attacked “mysticism” as heterodox and socially deviant.
Father Dimitri Dudko and the Intersection of late Cold War Underground, Official, and Diaspora Russian Orthodox Church Opinion
Authors: Kizenko Nadieszda
Published: November 2022

Father Dimitri Dudko’s fame as a popular 1970s Soviet Orthodox priest and his public ‘recantating’ and subsequent disgrace in 1980 shed light on several aspects of religion in the late Cold War. Diasporas like the ROCOR fostered practices and beliefs-especially conservative ones-forced to go underground in the homeland. Soviet atheism responded to revived religious practice worldwide, with Dudko’s persecution being a part of that response. The formal and informal relationships between ROCOR clerics and Dudko, and between Dudko and the KGB, suggest that Dudko’s apparent about-face may have had deeper roots and longer-lasting effects than previously suspected.
Chronicling the Underground: The Diary of an Old Calendarist Monastic Brother
Authors: Șincan Anca
Published: November 2022

The secret police archives present the life of the religious underground as seen by the secret officers who were seeking to facilitate those communities’ destruction. The state’s official narrative about these clandestine groups is mirrored in alternative documents and narratives. This article focuses on the Old Calendarist Orthodox monastic community of the Dormition of the Mother of God Monastery in the Strada Televiziunii in Bucharest at the end of the communist regime. It showcases the life of the monastery as described in the diary of a monastic novice whose written account of becoming a monk described the last days of the monastery before its destruction by the secret police in 1983.

Objective

Our goal was to characterize a cohort of heart failure patients with and without COVID-19 in terms of demographics, comorbid conditions, treatment regimens, lab test results and outcome.

Methods

We performed a retrospective, unicentric, cohort study on consecutive patients admitted to our department between September and December 2021.

Results

We enrolled a total of 76 HF patients – 65.3% COVID-19 (+). The median age was 72 years with a female predominance (59.2%). The median length of hospitalization was 13 days, longer for COVID-19 (+). Only 20.7% of all patients were fully vaccinated. COVID-19 (+) patients had higher ICU admission rates and mortality (in-hospital and at follow-up). The most common associated conditions were HTN (78.9%), T2DM (38.2%), cancer (18.4%), CAD (17.1%), late-stage CKD (16.7%), AF (14.5%) and stroke (11.8%). Patients with a history of stroke were more likely to require ICU management. At-home treatment with ACEi/ARB/ARNi made no difference for COVID-19 severity (p = 0.393), mechanical ventilation (p = 0.101) or mortality (in-hospital: p = 0.316; follow-up: p = 0.563); however, ICU admission rates were lower in these patients (p = 0.023).

Conclusion

Heart failure with preserved ejection fraction and low symptom severity were common findings among COVID-19 positive patients. However, COVID-19 positive patients were hospitalized for longer, required more ICU care and had higher mortality both in-hospital and at follow-up.
Caducidad o decaimiento administrativo por prescripción, preclusión y resolución
Authors: Arancibia Mattar Jaime
Published: November 2022

La regulación parcial de la extinción de algunas figuras jurídicas administrativas ha sido un terreno fértil de incertidumbre en Chile. En la actualidad, el autor de un hecho gravado con sanción o tributo desconoce si el atraso excesivo del Estado en pronunciarse sobre el gravamen implicará un estado de indefinición permanente por imprescriptibilidad de la potestad o por interrupción o suspensión del plazo para ejercerla debido al inicio del procedimiento administrativo; o si su perplejidad tendrá fecha de término por aplicación de plazos de preclusión o de prescripción fatales, propios o análogos (civiles, penales), o por declaración de decaimiento procedimental. Esta incerteza jurídica se debe, principalmente, a la variedad de postulados acerca de las interrogantes planteadas en la doctrina y la jurisprudencia. Mientras unos contribuyen al estado de indefinición de la situación del autor del hecho gravado, otros procuran solucionarlo no siempre de modo coherente o en armonía con los intereses públicos en juego. Este trabajo tiene pretende contribuir a la solución de los problemas prácticos y de incerteza que produce el atraso o inactividad administrativa de un modo que compatibilice intereses privados y públicos. Se propone recuperar el concepto de caducidad o decaimiento administrativo como efecto extintivo genérico conforme a su etimología y naturaleza jurídica, definir sus rasgos esenciales, y asignar una denominación y régimen específico a las causales que lo provocan, en particular, la prescripción, la preclusión y la resolución.

The main problems encountered in the long storage of printed or painted images are associated with deterioration of color characteristics and loss of information from them. The changes, that occur are due to the processes of ageing of the inks and papers. Natural ageing is a rather slow process. Therefore a study of the changes occurring with the printed images over the time under artificial UV radiation has been carried out. For the purpose of this experiment, was designed specialized test form, containing thousands of control patches for estimating the spectral, color and optical density shifts during the artificial ageing. The main goals of this research are to investigate the influence of artificial UV ageing on the optical density, spectral and color characteristics of printed images. The experiment have been performed in real printing conditions on state of art offset printing presses. The printing media used in the experiment are matte coated and uncoated offset paper, which are chosen because they are wide used all over the world. The test images and all the thousands of color control patches have been submitted to UV artificial ageing. The spectral and color characteristics of the inks and paper were examined during the different UV ageing period. The obtained results shows changes in all of investigated parameters during artificial ageing. The results are important from scientific and practical point of view. They might be used for modeling of ageing processes and could be very useful for recovering of original color characteristics of aged images.
Designing a co-curricular program to support project-based learning in the engineering curriculum
Authors: Richert Dean , Benoit Michael
Published: November 2022

There are many challenges related to the implementation of project-based learning (PBL) in the engineering curriculum. The amount of work required by instructors to design well-posed projects is a barrier to the broad adoption of PBL. On the other hand, poorly designed PBL activities often cause frustration among students, create extra work for instructors and students alike, and generally detract from the intended learning outcomes. In this paper we introduce a unique co-curricular program that supports instructors in the creation of high-quality and high-impact PBL activities. The program is innovative as it involves and benefits multiple stakeholders including students employed through the program, faculty, industry, and the engineering curriculum. The ongoing efforts to improve the program are also described.
Education As Prototype: On a Combined Architecture-Engineering Design Tutorial
Authors: Nolan Edmund , Davis Jennifer
Published: November 2022

This article uses expert interviews to support the need for architecture-engineering collaborations in undergraduate education and uses teaching practice reflection to evaluate an example of such a collaboration at work. We establish the state of such collaborations in professional practice and use that as context to consider the design of an undergraduate architecture-engineering collaborative tutorial. We find that while the experiential, project-based educational model employed can mimic key aspects of professional practice, there are limitations to what can be delivered in a one-term experience. Key to understanding those limitations and decisions are the two diagrams provided in the article, which visualize the tutorial and the courses it is attached to as interrelated learning environments. We find that such a tutorial—in addition to delivering core content knowledge to students in each discipline—should create an environment in which students can develop key interdisciplinary skills and abilities, especially as regards communication, teamwork and interpersonal relations. We also reflect on the key design decisions behind the current iteration of the tutorial and identify future considerations for both the tutorial and this research project, of which this article is intended to be the initial stage.
Rethinking the Engineering Design Process: Advantages of Incorporating Indigenous Knowledges, Perspectives, and Methodologies
Authors: Forrest Reed , Seniuk Cicek Jillian
Published: November 2022

A recent increase in interest in the inclusion of Indigenous Ways of Knowing in engineering education has led to the discussion on how to bridge the worldviews of Indigenous Peoples and modern engineers. A literature review was performed to identify issues in current engineering practice, explore the value of perspective in the process of problem solving, distinguish the differences between engineering and Indigenous worldviews, analyze how these worldviews are compatible and incompatible, and formulate a general approach and value system for engineers going forward. Findings show that there is a need to revise how engineers approach problems, and that the consideration of alternative perspectives can provide new avenues for solving problems. There were indications of potential for symbiosis between Indigenous cultures and engineering, as the inclusion of Indigenous knowledges in engineering and engineering education would not only preserve Indigenous cultures, but alsoimprove the quality of engineering design solutions.

Published: November 2022

Chinese wisteria (Wisteria sinensis), Glycine chinensis, is a genus of treelike deciduous lianas from the legume family (Fabaceae). In natural conditions, Glycine chinensis is found in the subtropical forests of China, Korea and Japan. Nowadays, the plant is widely cultivated in European countries. Leaves of the plant exhibit the antioxidant,cytostatic effect, flowers inhibit the growth of tubercle bacilli. The seeds are used in Chinese medicine to treat cardiovascular diseases and as a diuretic.
Aim. To study macro- and microscopic features of Chinese wisteria leaves for standardization of the medicinal plant raw material and development of the quality control method.
Materials and methods. The study object was the leaves of Chinese wisteria harvested in the period of mass flowering in the Kyiv region and the Autonomous Republic of Crimea. The morphological features were studied visually. Preparations from the leaf surface were prepared according to conventional methods.
Results and discussion. The main morphological and anatomical features of Chinese wisteria leaves have been determined. Macroscopic features include complex unpaired leaves that have a common petiole and its continuation – rachis, on which there are five pairs of opposite leaves and one apical one. The leaves are large, do not have a toothed edge, pubescent at first, but eventually become smooth; microscopic signs are the dorso-ventral type of theleaf blade structure. The epidermis is covered with a cuticle. The cells of the upper epidermis are parenchymal, slightly convoluted, with evenly thickened membranes. Above the vein, the cells are prosenchymal, elongated along the vein. The lower epidermis is represented by cells of various shapes, parenchymal or having a somewhat elongated shape, sinuous-walled, polygonal. Stomata are frequent and oval. The stomatal apparatus is of anisocyte type. There are numerous hairs along the central vein and on the petiole. The petiole of the leaf has a rounded shape. In the center there is a single conductive bundle surrounded by parenchymal cells. The epidermis consists of small erect cells. There are numerous simple unicellular hairs. The cross-section of the rachis has an oval-triangular shape, the tubercles are ribshaped. Stomata are present.
Conclusions. As a result of the studies, the main macroscopic and microscopic features of Chinese wisteria leaves have been determined; they will be used to standardize the medicinal plant raw material and develop the quality control method.

Dari total 64 responden, 34 responden yang pernah terinfeksi COVID-19, gejala vaksinasi booster dirasakan lebih ringan pada 3 (8,8%) dan lebih parah pada 31 (91,2%) responden. Sementara itu, 30 responden lainnya yang belum pernah terinfeksi COVID-19 lebih ringan pada 1 (3,3%) dan lebih berat pada 29 (96,6%) responden. Hasil uji statistik dengan Pearson Chi-Square menunjukkan hubungan yang tidak signifikan antara riwayat infeksi COVID-19 dengan tingkat keparahan gejala vaksinasi booster (p-value: 0,365). Kesimpulan: Infeksi COVID-19 tidak mempengaruhi tingkat keparahan PIAE ringan atau berat pada responden dewasa muda. Diperlukan penelitian dengan jumlah responden yang lebih banyak diikuti dengan model acak.

Penelitian untuk mengetahui pengaruh dehydroepiandrosterone (DHEA) terhadap aktivitas peroksidasi lipid dan konsentrasi nitrit oksida pada aorta tikus wistar jantan akibat paparan asap rokok. Penelitian ini merupakan eksperimen laboratorium dengan menggunakan 21 ekor tikus yang dibagi menjadi 3 kelompok yaitu KN-14 (kontrol negatif yang diberikan paparan asap dalam waktu 14 hari), DHEA-1 (15 mg/kgBB + paparan asap selama 14 hari), dan DHEA. -2 (30 mg/kgBB + paparan asap selama 14 hari). Pemaparan dilakukan selama 25-45 menit dengan 4 batang rokok/hari. Pembedahan dilakukan pada hari ke-15 untuk mengangkat aorta untuk memeriksa malondialdehid (MDA) sebagai biomarker peroksidasi lipid dan konsentrasi oksida nitrat (NO) menggunakan Enzyme-linked Immunosorbent Assay (ELISA). Hasil penelitian menunjukkan bahwa peningkatan signifikan konsentrasi MDA ditemukan pada kelompok yang diberikan DHEA, terutama pada dosis 30 mg/kgBB (p<0,05). Sedangkan pemberian DHEA dosis 15 dan 30 mg/kgBB tidak berpengaruh nyata (p>0,05) terhadap konsentrasi NO aorta dibandingkan dengan kelompok KN-14. Oleh karena itu, dapat disimpulkan bahwa pemberian DHEA dapat meningkatkan aktivitas peroksidasi lipid yang ditunjukkan dengan peningkatan signifikan konsentrasi MDA aorta, tanpa mempengaruhi konsentrasi NO aorta pada tikus yang terpapar asap rokok selama 14 hari.

Organisasi Kesehatan Dunia (WHO) merekomendasikan agar bayi hanya disusui dengan ASI selama minimal 6 bulan. Berdasarkan data Dinas Kesehatan Kabupaten Pidie tahun 2017, pemberian ASI eksklusif untuk bayi 0-6 bulan sebesar 25% sedangkan targetnya 100%, sehingga dari data tahun 2017 masih jauh dari target. Pada tahun 2018 terjadi peningkatan pencapaian ASI eksklusif sebesar 59% dan pada tahun 2019 terjadi peningkatan sebesar 63%. Berdasarkan Data Profil Puskesmas Kabupaten Sakti Pidie tahun 2017 sampai dengan tahun 2019, pencapaian pemberian ASI eksklusif pada bayi usia 0-6 bulan tahun 2017 sebesar 14%, tahun 2018 persentasenya menurun menjadi 11% dan tahun 2019 meningkat menjadi 43% . Hal ini menunjukkan bahwa masih banyak bayi yang tidak mendapatkan ASI eksklusif. Tujuan penelitian ini adalah untuk mengetahui faktor-faktor yang berhubungan dengan pemberian ASI eksklusif pada bayi usia > 6 bulan - 24 bulan di Wilayah Kerja Puskesmas Sakti Kabupaten Pidie Tahun 2020. Penelitian ini menggunakan desain studi potong lintang. Penelitian ini dilaksanakan di Puskesmas Sakti Kecamatan Kota Bakti Provinsi Aceh pada bulan Februari sampai dengan Maret 2020. Penelitian ini terdiri dari dua variabel yaitu variabel terikat (yaitu pengetahuan, pekerjaan, inisiasi menyusu dini, dukungan suami dan dukungan tenaga kesehatan) dan variabel bebas ( eksklusif). menyusui). Berdasarkan analisis bivariat didapatkan bahwa tidak ada hubungan yang signifikan dengan pemberian ASI eksklusif yaitu pengetahuan (0,102), pekerjaan (0,431), inisiasi menyusu dini (0,052) dan dukungan tenaga kesehatan (0,491). Ada hubungan antara dukungan suami dengan pemberian ASI eksklusif (0,0310) di Puskesmas Sakti Kecamatan Sakti Kabupaten Pidie Tahun 2020. Hasil penelitian ini membuktikan bahwa tidak ada hubungan yang signifikan antar variabel (pengetahuan, pekerjaan, inisiasi dini pemberian ASI dan dukungan tenaga kesehatan) dan ASI Eksklusif di Puskesmas Sakti.

Financial statements are an important instrument for every company which is not only a means of making decisions by the company's internals alone, but also to assess the condition or condition of the company by external parties as well. In recent years, manipulation of audited financial statements caused by auditor violations often occurs, so that public doubts arise over the quality of audits produced by auditors. This study aims to determine the effect of audit fees, audit tenure, audit rotation and KAP size on audit quality. Sampling was carried out using the purposive sampling method and resulted in a selected sample of 59 manufacturing companies multiplied by a five-year observation period, so that the total number of observation data was 295. The research data used in this study were secondary data taken from the annual report. manufacturing company registered on ISSI from 2016-2020. This study implies a descriptive research design using a quantitative approach. Data analysis in this study uses logistic regression analysis which is processed using STATA version 16 test tool. The results of this study indicate that audit fees have a positive effect on audit quality, audit tenure and KAP size have no effect on audit quality, while audit rotation has a negative effect on audit quality.

Background:

Pediatric intracranial aneurysms (PIAs) are uncommon. Flow diverters (FDs) have shown to be effective on treatment of selected aneurysms.

Methods:

We describe 10 cases of PIAs treated with FDs at one medical center in Mexico, from April 2015 to April 2020.

Results:

Out of 230 patients treated with FDs, 10 (4.3%) were pediatric. Average age was 9.4 years old (R: 6–15). Two patients (20%) had subarachnoid hemorrhage, 3 had epilepsy (30%), 3 (30%) had clinical signs of cranial nerve compression, and 4 (40%) had only headache. Two patients were in 1a grade of Hunt and Kosnik scale. Out of the nonruptured aneurysms, 7 (70%) were in 15 points of Glasgow Coma Scale and 1 patient (10%) was in 13 points. Treatment was performed without complications; nevertheless, appropriate distal deployment was not achieved in one case. At discharge, nine patients had 5 points of Glasgow Outcome Scale. All patients underwent computed tomography angiography or digital subtraction angiography at 1, 3, 6, and 12 months, 2 patients (20%) had a 2-year follow-up, and 3 patients (30%) had a 3-year follow-up. According to Kamran grading scale, 9 patients (90%) were classified as Grade 4 and 1 patient (10%) as Grade 3.

Conclusion:

Even though it is a small series, as this is an uncommon disease, we may suggest that FDs are useful to treat properly selected PIAs. Our study has consecutive imaging assessment at least a year of follow-up in which aneurysm stable occlusion was observed in 90% of patients.
