El regreso de Lula: escenarios para la nueva presidencia de Brasil
Authors:   investigadora sénior, CIDOB, Ayuso Anna , da Silva Bichara Julimar ,   Profesor titular, Departamento de Estructura Económica y Economía del Desarrollo, UAM
Published: November 2022

La elección de Luiz Inácio Lula da Silva para un tercer mandato en la presidencia de Brasil supone un revulsivo para un país que enfrenta grandes retos –políticos, sociales y económicos– en un contexto nacional e internacional convulso. En una sociedad fuertemente polarizada y con unos órganos legislativos claramente escorados a la derecha, la gobernabilidad se verá condicionada por las coaliciones y los pactos ad hoc. El escenario económico debe contemplar las incertidumbres de la economía mundial, con ralentización del crecimiento económico, restricciones en las cadenas productivas de valor, inflación y tipos de interés elevados. El nuevo presidente tendrá que hacer frente a demandas sociales urgentes, como la disminución de la pobreza y el hambre, así como la recuperación de las políticas sociales redistributivas, con un margen fiscal muy limitado.
Selling out for sustainability? Neoliberal governance, agency and professional careers in the sustainable palm oil sector
Authors: Delabre Izabela , von Hellerman Pauline
Published: November 2022

In response to high-profile activist campaigns raising public awareness of the destructive effects of large-scale oil palm plantations on tropical rainforests, wildlife and local communities, the palm oil sector has put considerable effort and resources into ensuring "sustainable", "deforestation-free" palm oil production (and thereby countering negative publicity) over the last 15 years or so. The corporate sustainability drive – with the palm oil sector significantly leading other tropical commodities – has involved the direct employment of many professionals with backgrounds in conservation, anthropology or activism by the private palm oil sector. Based on long term participant observation as well as interviews with "sustainability professionals" about their career choices, this article shows that there is more nuance, agency and positive change than the existing political ecology literature attributes to the sustainable palm oil drive. It also shows how neoliberal governance structures and individual professional careers and values intersect and mutually reinforce each other. This dual, seemingly paradoxical analysis is informed by and situated in the wider context that the sustainability professionals we interviewed and we ourselves, as academics, share: growing academic precarity, the climate and ecological emergency, and the challenges and questions posed by both.

This research paper in its first part focuses on the theoretical concepts of “innovation”, “innovation Management”, and “ICT innovation management”. The second part of the paper aims to follow results of the survey (research methodology) in determining whether the innovation is of interest to the participants of the survey. It questions whether ICT innovations are the key for economic development of the country, or if the interviewees own their (patented) ICT innovative product. It questions where the interviewees find motivation for creation of ICT innovation and if the managers consider opening vacancies for ICT innovation development. It questions whether they are familiar with the Strategy of Innovation Incentives in the Republic of Croatia, in the period 2014-2020, or whether the interviewees believe it was real and achieved. Did the interviewees know that the Republic of Croatia was behind Slovenia, Hungary and Bulgaria according to the Index of Innovation, and if they agree with the statement that innovations are the source of real competitive advantage of individual business, and one of the most efficient ways for sustainable prosperity. Are the SMEs (small and medium enterprises) the cornerstones for development of modern economy?
Design and Testing of Multi-Material Shape-Changing Flexure Hinges for Fused Filament Fabrication
Authors: Ermolai Vasile , Nagîţ Gheorghe , Sover Alexandru , Surugiu Ioan
Published: November 2022

Living hinges are non-assemblable flexible joints that allow the relative rotation of two adjacent rigid parts through bending. Conventionally, living hinges are single-material designs made through injection moulding, for example. In order to reduce mould complexity, flexure hinges have a restrictive design. However, 3D printing technologies, such as Fused Filament Fabrication - FFF, can provide new opportunities for hinge development, allowing more design freedom and a wide range of materials. This paper focused on exploring and testing various multi-material hinges designs with bidirectional folding made of compatible and low-compatible thermoplastic materials. The resulting designs have corrugated structures and shape-changing interfaces, each with multiple solutions. They were printed as samples made of acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) for the rigid bodies and with thermoplastic co-polyesters (TPC) for the hinge. The results show that corrugated and shapechanging structures can be used as a design solution for flexure hinges.
Restoring River Connectivity in Line with European Legislation
Authors: Moldoveanu Alexandru , Popescu Daniela
Published: November 2022

Water Framework Directive defines the river longitudinal continuity as “undisturbed migration of aquatic organisms and sediment transport”. Electrical energy production from hydro sources is the main risk that generates hydromorphological alteration of surface waters by disconnecting the rivers. The flow reduction on the river sector from the water intake to the restitution point of the small hydropower plant is also considered as a hydromorphological alteration that can modify the natural hydrological regime.

This paper presents good practices for ensuring the river longitudinal connectivity while Small Hydropower Plants are implemented. In order to restore the river longitudinal connectivity for fish migration, some types of fish passages used within the hydropower facilities from Europe are presented and discussed.

The recommended solutions are important to mitigate the small hydropower plants’ negative effects on river ecosystems and it can contribute to the increase of energy power units based on renewables.

Authors: Radi Al-Aga Suhail F. , Burhan Abbas M.
Published: November 2022

The identification of risks in construction projects gives advance indications of the potential risks that may occur during project planning, construction or management. Therefore, identifying those risks and preparing the necessary plans to respond to them is a key detail for the success of the project from its failure. The projects implemented in the manner of a Build Operate Transfer (BOT) contract are accompanied by many risks due to the multiplicity of parties and the multiplicity of their responsibilities, as well as the size of those projects because they are usually associated with infrastructure projects. The aim of this research is to identify the most prominent risks in BOT contracts and the planned response against each risk. The adopted methodology is through conducting interviews and a closed questionnaire (included 77 out of 100 respondents), and the adoption of statistical analysis through the SPSS program and the scale of relative importance.The relative importance index technique was used to rank the risks according to their importance and discuss the reasons for their classification. The results showed a list of the most important risks that would be generated if the BOT contract was applied to transportation projects in Iraq, as well as the appropriate planned response to each risk based on historical information for previous BOT projects.

Authors: Nugroho Fajar , Maidiawati  , Tanjung Jafril , Zaidir
Published: November 2022

A simple and accurate analytical model for defining the lateral strength of the multi-span RC frame with masonry infill has been developed in this study. This model is developed due to the limitation of the current analytical model which only can be applied to the single-span RC frame. Meanwhile, the structure in the building also is in a multi-span frame and masonry infill greatly impacts the portal structure. In the existing building, this analytical method is needed to calculate the lateral strength of the RC frame. Besides, the analytical method was developed based on the lateral strength analysis method of a single-span RC frame in which the modeling of a multi-span RC frame with masonry infill along with uniform span spacing was applied. Furthermore, an equivalent diagonal strut with the same thickness and material as the masonry panels was used instead of masonry infill in the frame structure. The external column has diagonal compressive forces on the top or bottom of the column. On the other hand, diagonal compressive forces work at the top and the bottom of the column in the internal column. The lateral strength of the infill was determined based on the frame infill contact length. Furthermore, in order to obtain the lateral strength of the structure, the experimental study of a multi-span RC frame with masonry infill under cyclic load was also tested. Applying the analytical model has shown promising results even after being compared with the results of the experimental work.

Authors: Al-Hilali Amjad Majeed , Izzet Amer Farouk
Published: November 2022

A long-span Prestressed Concrete Hunched Beam with Multi-Quadrilateral Opening has been developed as an alternative to steel structural elements. An experimental program was created and evaluated utilizing a single mid-span monotonic static load on simply supported beams, which included six beams with openings and the solid control beam without openings, to investigate the performance of such beams. The number and height of the quadrilateral openings are the variables to consider. According to test results, the presence of openings in the prestressed concrete hunched beam with multi-quadrilateral opening did not considerably affect their ultimate load capacity with respect to a control beam (solid); the diminishing ratio of maximum strength capacity varied from 4.22 % to 13.5 %.

Effect of Lime Filling on the Compactibility of Clay Soils
Authors: Bulko Roman , Masarovičová Soňa
Published: November 2022

Insufficient resilience of the natural environment is one of the many problems with the foundation of linear structures, and one of the ways to solve the foundation of a linear structure is the stabilization of soils. Fine-grained soils are problematic for traffic construction. The properties of clay soils change due to climatic conditions. They swell and become plastic in the presence of water, shrink in dry conditions, increase in volume, and freeze due to frost. Improving the properties of fine-grained soils with lime is a suitable solution to the problem in traffic construction. The purpose of soil improvement is to modify soil properties such as creating soil without cavities and gaps, increasing shear strength, reduce compressibility and permeability, the soil must be able to transfer the load without further settling (or unnatural compression). Soil improvement can be defined as an intervention in the natural geological environment or artificially built earth structures (embankments, notches), the purpose of which is to increase the resistance of the subsoil, achieve even settlement of the structure or object, accelerate consolidation, optimally build earth structures, etc. We can encounter the stabilization of the subsoil in all types of constructions, but most often in line constructions and water management construction. In our article, we focus on the effects of soil treatment with lime. The treated soil was F8 (CH) clay with high plasticity.

Authors: Hubová Oľga , Franek Michal , Véghová Ivana
Published: November 2022

The value of the total aerodynamic resistance of the structure is depended on the values of the highly variable coefficients of external pressure, the quantification of which is a typical task of aerodynamics of structures solved on a rigid model in a wind tunnel. The aim of the paper is to analyze the distribution of wind pressure on a 150 m high chimney of a nuclear power plant. Due to today’s changing climate and the emergence of unwanted windstorms, it is necessary to pay increased attention to tall and slender structures, where the effects of wind play an important role. The effect of wind, the influence of the terrain and surrounding structures has a significant impact on the safety of the chimney, which is a part of the nuclear power plant, where increased safety is required not only for the chimney itself but also for buildings in its immediate vicinity. Surrounding structures can modify wind flow and cause increased chimney load. Experimental measurements were performed in the STU BLWT wind tunnel in Bratislava, where the influence of the changing terrain, as well as the influence of the surrounding objects on the external wind pressure coefficients at different altitude levels were monitored.

Authors: Fahad Mohammad , Nagy Richard , Gosztola Daniel
Published: November 2022

In situ monitoring of pavement health has been getting much attention due to the efficiency, reliability and accuracy of data. This review consists of various embedded as well as nondestructive sensing options that have been used to perform analysis on pavement health either by simply calculating horizontal and vertical strains under pavement layers or by crack detection models inside pavement structures by supplementing information from moisture, temperature and traffic related sensors. With optimum integration of such combination sensors, engineers can predict the optimum rehabilitation time of the pavements and reduce a huge amount of budget spent on infrastructure reconstruction.

Authors: Panulinova Eva , Harabinova Slávka
Published: November 2022

The paper deals with the process of environmental risk assessment from exposure to noise from tram traffic. As part of the monitoring of the acoustic situation, measurements of sound pressure levels A were made and evaluated. The survey confirmed the existence of an acoustic risk in the form of a disturbing wailing sound when a tram vehicle passes through a directional curve with a radius of less than 50m. In addition to causing annoyance, the tonal variation of sound above 65 dB causes frostiness, cardiovascular, psychological and auditory problems, thereby damaging the health of people living and moving around the transport routes.
Impact of Strength-Enhancing Admixtures on Stabilization of Expansive Soil by Addition of Alternative Binders
Authors: Lindh Per , Lemenkova Polina
Published: November 2022

In this study, the stabilization process is introduced to a clayey expansive soil collected in southern Sweden. The tests examined strength parameters of expansive soil stabilized by different binders using combination of both traditional binders (cement and lime) and alternative materials (slag Merit 5000, fly ash from SCA Lilla Edet and fly ash from coal combustion, ISO certified). The practical goal was to find a binder mixture that is optimized for soil stabilization with respect to technical properties of stabilizing agent as an inert ballast material. The strength of soil stabilized by various binders was examined by velocity of the P-waves propagating through specimens. The results show that introducing slag Merit 5000 as an admixture to cement and lime is an effective approach in enhancing strength properties in weak soil, which increases bearing capacity of soil for planned construction works. The results also shown that a mixture of lime and bio ash yields a better effect in the stabilization of a clay. Soil stabilized with cement, cement/slag and lime/slag becomes resistant to freeze-thaw cycles, which is crucial for construction of roads and building foundations.

Introduction:
Curcuma xanthella Škorničk. is a rare species. Recently, it has been described as a new species from Vietnam.

Objective: In this study, the chemical composition of the acetone extract as well as the antibacterial and antioxidant effects of acetone extract and its fractions such as n-hexane, chloroform and ethyl acetate of C. xanthella were investigated for the first time.

Methods: The chemical components obtained from the acetone extract of C. xanthella were performed by using gas chromatography/mass spectrometry assays. Disc diffusion assay was used to assess the antibacterial effects of studied samples. Free radical scavenging ability of the extracts was determined by DPPH free radical scavenging (DPPH RSA) assay.

Results: Sixty chemical compounds were reported from C. xanthella, of which 1,8-cineole (11.3%), n-hexadecanoic acid (11.13%), stigmasterol (8.2%), γ-sitosterol (6.78%) and neophytadiene (6.71%) were the major compounds. The acetone extract and its fractions such as n-hexane and ethyl acetate were found to be effective against eight oral bacteria, including Escherichia coli, Klebsiella pneumoniae, Shigella flexneri, Salmonella enteritidis, Salmonella typhimurium, Pseudomonas aeruginosa, Bacillus cereus and Staphylococcus aureus. The acetone extract and its fractions such as n-hexane, chloroform and ethyl acetate of C. xanthella showed DPPH radical scavenging activity with IC50 value of 6.60, 2.38, 8.45 and 3.42 mg/ml, respectively.

Conclusion: Sixty chemical constituents were identified in the acetone extract of C. xanthella. The acetone extract and its fractions showed antibacterial effect and DPPH radical scavenging activity.
The Influence of Anticipation of Movement Starting Time on Feedforward Activation of Trunk Muscles During Rapid Shoulder Joint Movements
Authors: Oshikawa Tomoki , Adachi Gen , Akuzawa Hiroshi , Okubo Yu , Kaneoka Koji
Published: November 2022

This study aimed to clarify the differences in the onset of trunk muscle activity with and without anticipation of the movement starting time during rapid shoulder movements. Ten healthy men in a relaxed upright position performed rapid 135° flexion, 135° abduction, and 45° extension of the shoulder on the dominant hand side with and without anticipation of the movement starting time. They moved their shoulder joints following a 3-s countdown and a light stimulus in the anticipation and non-anticipation conditions, respectively. Electromyography of the anterior and posterior quadratus lumborum, transversus abdominis, internal oblique, external oblique, rectus abdominis, lumbar multifidus, lumbar erector spinae on the non-dominant hand side, and the middle deltoid on the dominant hand side were measured. The onset of activity of each trunk muscle relative to the onset of the middle deltoid was calculated. Two-way analysis of variance (eight trunk muscles × two anticipation conditions) was used to compare the onset of electromyographic activity of the trunk muscles in each direction of the shoulder movement. There were significant interactions between the muscles and anticipation conditions during shoulder abduction and extension. The onset of activity in the anterior and posterior quadratus lumborum, transversus abdominis, and internal oblique occurred earlier with anticipation of the movement starting time than without anticipation during shoulder abduction and extension. The anticipation of movement starting time may contribute to a reliable center of mass control within the support base and improve lumbar spine stability by hastening the onset of activity of the deep trunk muscles.
Strength and Power Performance Changes During an In-Season Resistance Training Program in Elite Futsal Players: A Case Study
Authors: Luís Marques Diogo , Nuno Ribeiro João , Carlos Sousa António , Travassos Bruno , Cardoso Marques Mário
Published: November 2022

In this study, we aimed to analyze (i) the strength and power changes after resistance training (RT) in elite futsal players, and (ii) the associations between the session rate of perceived exertion (sRPE) and perceived total quality recovery (TQR), and the sRPE and TQR with the volume load of the RT program. Ten elite futsal players (24.8 ± 5.4 years; 76.2 ± 7.1 kg; 1.77 ± 0.05 m) performed an in-season 8-week RT program twice per week. RT consisted of 2-3 sets x 3-6 reps at 45-65% of one-repetition maximum (1RM) with maximal velocities in the full squat and complementary exercises with the same volume. We assessed the TQR before every session, while the sRPE was calculated after each RT session. One week before and after the intervention, we measured the countermovement jump (CMJ) height, isometric hip adduction strength (IHAS), 1RM, and peak power (PP) in the full squat progressive loading test. After the 8-week training program, there was a significant improvement in most outcomes, yet the gains (%Δ) remained below the minimal detectable change (MDC), except for IHAS (CMJ: p < 0.05, %Δ = 6.7, MDC% = 7.2; IHAS: p < 0.001, %Δ = 19.1, MDC% = 14.6; 1RM: p > 0.05, %Δ = 9.2, MDC% = 21.5; PP: p < 0.05; %Δ = 14.4, MDC% = 22.4). We also found a significant negative correlation between TQR and the sRPE (r = -0.45, p < 0.001). Our data suggest that RT based on low-volume and low-to-moderate loads may not produce a sufficient stimulus to induce meaningful dynamic strength and power gains in elite futsal players, although it improves isometric strength. Furthermore, monitoring TQR before sessions may show coaches how the elite futsal player will perceive the session's intensity.
Malignant Evolution of Schnitzler Syndrome to Waldenström Macroglobulinemia: a Case Report
Authors: Man Cristina-Alexandra , László Nimród , Horváth Emőke , Demian Smaranda
Published: November 2022

Introduction: Schnitzler syndrome (SchS), first described in 1972, is a rare autoinflammatory condition characterized by chronic urticaria and monoclonal gammopathy of IgM or, exceptionally, IgG profile. Additional features include recurrent fever, evidence of abnormal bone remodeling, a neutrophilic dermal infiltrate on skin biopsy, leukocytosis or elevated C-reactive protein, according to the Strasbourg criteria.

Case Presentation: We describe the case of a 56-year-old Caucasian male patient, who suffered from chronic urticaria, moderate-grade fever, severe generalized fatigue and arthralgias. After five years of chronic disease evolution, he was referred to the hematology department where he was found to have IgM kappa light chain monoclonal gammopathy. The constellation of symptoms, a negative rheumatologic workup, and the finding of IgM monoclonal gammopathy determined the diagnosis of Schnitzler syndrome. Bone marrow biopsy proved the association of Waldenström macroglobulinemia.

Conclusion: The main goal of our case report was to highlight the clinical features and treatment, with emphasis on the hematological aspects, to provide a better understanding and to raise awareness of Schnitzler syndrome among healthcare professionals.
Some notes on dynamic oligopsonies
Authors: Hamidi Maryam , Szidarovszky Ferenc , Matsumoto Akio
Published: November 2022

A special oligopoly model is considered when the firms compete on the factor market, and the used factor volumes determine their outputs. In the Nfirm case conditions are given for the existence of the Nash equilibrium, and in the cooperative case, sufficient conditions are derived for the existence and uniqueness of the joint profit maximizer. In the case of a linear duopoly the dynamic extensions are introduced in both cases based on gradient adjustments. Conditions are given for the local asymptotic stability of the equilibrium and the joint profit maximizer without and with information delays.

Published: November 2022

In this paper we determine the asymptotic behavior of the Non-dictatorship Index (NDI) introduced in Bednay, Moskalenko and Tasnádi (2019). We show that if m denotes the number of alternatives, then as the number of voters tends to infinity the NDI of any anonymous voting rule tends to (m − 1)/m, which equals the NDI of the constant rule.
On monotone likelihood ratio of stationary probabilities in bonus-malus systems
Authors: Ágoston Kolos Csaba , Gyetvai Márton
Published: November 2022

Bonus-malus system is an often used risk management tool in the insurance industry, and it is usually modeled with Markov chains. Under mild conditions it can be stated that the bonus-malus system converges to a unique stationary distribution in the long run. The maximum likelihood ratio property is a well-known statistical concept and we define it for the stationary distribution of a bonus-malus system. For two special cases we could justify it algebraically. For other cases we describe a numerical method with which we can test this property in any case. With the help of the described method, we checked this property for cases that appear in actuarial practice.
Computability of sets in Euclidean space
Authors: Potgieter Petrus H
Published: November 2022

We consider several concepts of computability (recursiveness) for sets in Euclidean space. A list of four ideal properties for such sets is proposed and it is shown in a very elementary way that no notion can satisfy all four desiderata. Most notions introduced here are essentially based on separability of ℝ
n
and this is natural when thinking about operations on an actual digital computer where, in fact, rational numbers are the basis of everything. We enumerate some properties of some naïve but practical notions of recursive sets and contrast these with others, including the widely used and accepted notion of computable set developed by Weihrauch, Brattka and others which is based on the “Polish school” notion of a computable real function. We also offer a conjecture about the Mandelbrot set.
Solution of the real and complex eigenvalue problems in the ABS class
Authors: Abaffy József
Published: November 2022

The class of ABS methods was originally developed for solving systems of linear equations in a finite number of iterations. Later it was shown that methods for solving nonlinear systems of equations, linear programming algorithms, quadratic programming, etc. are also members of the ABS class. In this paper, we show that QR factorization can also be derived from three ABS subclasses, which is an essential step in methods solving eigenvalue problems. Another possibility to use the ABS class in the eigenvalue problems is to transform a matrix to Hessenberg form which is an important initial step when solving eigenvalue problems by QR-type methods. Here we study versions of the plain QR-method which are based on the QR factorization computed by the ABS methods and compare them with the MATLAB eig () function. We also compare the ABS Hessenberg method to the MATLAB hess() function. The preliminary results show the competitiveness of 3 ABS eigenvalue solving methods with the MATLAB eig () function.

Applying Cocoso, Mabac, Mairca, Eamr, Topsis and Weight Determination Methods for Multi-Criteria Decision Making in Hole Turning Process
Authors: Do Duc Trung , Nguyen Nhu-Tung
Published: November 2022

The ranking of solutions to determine the best one among many solutions is always the setting goal for all activities of all fields in general and in the turning process in particular. When a solution is evaluated by multiple criteria, this is known as “Multi-Criteria Decision Making - MCDM”. Many MCDM methods were proposed by scientists, however, the ranked results of the solutions are not the same. In addition, the ranked results of the solutions also depend on the weighting methods of the criteria. In this study, the ranking of the solutions in the hole turning process was performed by different MCDM methods and with different weighting methods. Five MCDM methods were mentioned in this study including COCOSO, MABAC, MAIRCA, EAMR, and TOPSIS. In this study, five weighting methods were also used including MEREC weight, EQUAl weight, ROC weight, RS weight, and FUCOM weight. The combination of MCDM and weighting methods creates twenty-five ranking results of the solutions. It is interesting to note that all twenty-five ranking results determine the same best solution. The stability in ranking the solutions by MCDM methods was also discussed in this study. From the obtained results, several recommendations were drawn. Some issues that have not been solved in this study and need to be done in near future are also mentioned in the last section of this study.

Published: November 2022

The effect of heat treatment in oxygen-containing medium on fatigue properties of zirconium alloy samples was shown. This gas treatment improved fatigue life in pure bending and cyclic tensile testing. An increase in fatigue life was explained by the formation of a hardened near-surface layer. According to the data of fractographic studies of destroyed samples, it was found that treatment in an oxygen-containing medium contributes to the formation of a structure with a higher energy intensity of destruction.

Authors: Tebergaoui Nabila Nehla , Djaouahdou Reda , Benhaoues Karima , Tăbîrcă Alina Iuliana
Published: November 2022

The extraordinary events of the COVID-19 pandemic have led Big 4 Audit Firms, like many other global companies, to a place where everything is different. Overnight, all practitioners worldwide have been forced to work in an entirely new environment that requires them to scramble for survival. However, the same destructive forces and the challenges of maintaining business continuity, as well as the widespread working home methods and providing remote services, have offered enormous opportunities and potentials for audit firms [in particular, Big 4 audit firms] to develop their digital innovations and increase reliance on modern technologies. Therefore, the main objective of our research lies in exploring the position of modern technologies (particularly in Big 4 audit firms) in activating the remote auditing approach considering the COVID-19 pandemic. So, in achieving the objectives of the research, we relied on the documentary descriptive approach, through which we reached several results, most notably that Modern technologies have contributed to drawing the line between what is possible in the external audit profession and what can only be imagined, by expanding the circle of possibilities and enabling auditors to practice their jobs anywhere, anytime and in real-time with the auditee, which translates into activating the remote auditing approach.

Published: November 2022

Choosing the right leadership style is a constant concern in business management because it can directly influence its financial results. Through this paper, we wanted to check to what extent the leadership style can influence the level of satisfaction of the employee, his desire to change jobs, and to what extent it accentuates or improves the effects generated by the COVID-19 pandemic (anxiety, work from home, the economic crisis generated]. We also wanted to check to what extent a high degree of job satisfaction can negatively influence the employee’s desire to look for a new job. In the empirical research, we used the MLQ questionnaire to determine the management style, and we used the Likert scale for other variables.

Published: November 2022

Corruption is one of the plagues of the modern world that is characteristic especially of the economic, administrative, and political areas. The history of civilization shows us that this phenomenon has existed in the world since the beginning. Still, depending on the era and the measures taken against it, it was more or less developed. From an economic perspective, it is considered to be particularly harmful because it constitutes an obstacle to the healthy, prosperous, and fair development of a nation. In our era, the phenomenon of globalization has acquired very strong valences, unfortunately, and corruption has acquired an impressive development, ripping the fruits of global deepening, especially now that we are also talking about corruption manifested across borders when it affects or is promoted by multinational companies. Of course, the phenomenon of corruption cannot be completely eradicated and there is no country in the world that can boast of such a performance, but firm measures are needed to limit and stop it.

Romania has been dealing with this phenomenon for a long time, and the legislative measures, the political will and the pressures of the European institutions should aim, in the medium term, to reduce it. The present article evokes the terminological aspects of the phenomenon of corruption, analyzing its causes and possible solutions, but also a perspective of mathematical modeling of its progression.

The study’s novelty is given by the deepening of the corruption phenomenon in light of the opportunities offered by the new paradigm of the globalization phenomenon.

Kualitas air dipengaruhi oleh tingginya aktivitas yang terjadi dikawasan pelabuhan perikanan dapat mengakibatkan pencemaran suatu lingkungan yang ditandai dengan penurunan kualitas air. Pencemaran air disebabkan oleh masuknya atau dimasukkannya mahkluk hidup, zat, energi, dan komponen lain ke dalam air oleh kegiatan manusia, sehingga kualitas air menurun sampai tingkat tertentu yang menyebabkan air tidak dapat berfungsi sesuai dengan peruntukannya. Tingkat pencemaran perairan Pelabuhan Perikanan dapat dilihat dari parameter fisika dan kimia yang meliputi, suhu, salinitas, pH (derajat keasaman) dan oksigen terlarut (DO).  Tujuan dari penelitian ini adalah untuk mengetahui kualitas air di kolam Pelabuhan Perikanan Samudera (PPS) Kutaraja untuk mewujudkan Pelabuhan Perikanan yang berwawasan lingkungan. Penelitian ini dilaksanakan pada bulan Februari 2021. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kuantitatif. Metode deskriptif kuantitatif adalah mendeskripsikan atau menjelaskan peristiwa atau kejadian yang terjadi pada saat sekarang dalam bentuk angka-angka yang bermakna. Berdasarkan hasil penelitian dengan metode indeks pencemaran, kondisi perairan di Pelabuhan Perikanan Samudera Kutaraja termasuk ke dalam kategori 1,0Pij5,0 yang berarti perairan Pelabuhan Perikanan dalam kategori tercemar ringan, dimana kriteria indeks pencemaran perairan mengacu berdasarkan Keputusan Menteri Negara Lingkungan Hidup Nomor 115 Tahun 2003 tentang penetapan status mutu air. Kondisi lingkungan Pelabuhan Perikanan Samudera (PPS) Kutaraja kurang stabil sehingga Pelabuhan Perikanan Samudera (PPS) Kutarja belum memenuhi syarat sebagai Pelabuhan Perikanan yang berwawasan lingkungan dikaji dari kualitas air

Patchouli waste (LAN) from essential oil distillation process is known to have high nutrient content and has potential as raw material for organic fertilizer. In this study, patchouli pulp was used as compost with the addition of biodecomposers of several Trichoderma species (T. harzianum, T.asperellum, T. hamatum, T. virens, and T. atroviride) to inhibit the development of budok disease in patchouli seedlings. Trichoderma spp. inoculated on a mixture of patchouli dregs, bran and manure. The mature LAN compost was mixed into the growing media before artificial inoculation of the pathogen Synchtrium pogostemonis in a 2:1 ratio. Parameters observed were incubation period and percentage of attack. The results showed that patchouli seedlings planted in media containing LAN compost with the biodecomposer T. harzianum did not show symptoms of budok disease until the end of the observation (42 days). LAN compost with T. asperellum biodecomposer was also proven to be able to extend the incubation period from 2.5 days (control) to 5.5 days. The greatest suppression of intensity was seen in the treatment of LAN compost with T. asperellum, T. virens, and T. atroviride biodecomposers, which was 6.25%. The results of this study indicate that the waste of patchouli dregs with the help of the decomposer Trichoderma spp. is a compost that has the potential to suppress S. pogostemonis attack on patchouli plants.
