Authors: Kevin Asshabul Kahfi  , Surya Nita  , Firmah Fadilla
Published: January 2023

The police are law enforcement officers who are given the authority to conduct investigations into criminal cases. The ability of investigators then determines the success of law enforcement. Recruitment of investigators working at the Directorate of General Crime at INP then needs to be done properly, so implementing talent scouting is the organization's choice. This paper aims to analyze the investigator recruitment scheme in one of the functions of the INP, namely the Directorate of General Crimes at the Criminal Investigation Agency by applying the concept of talent scouting. The method used in this research is descriptive research with a qualitative approach. Data was collected by literature study and documentation study. Secondary data sources are taken from books, journals, internal documents and others related to research problems. An interactive analytical framework was employed to analyze the data. The results of the study show that the implementation of talent scouting can be carried out by carrying out five stages: 1) announcement, 2) determination of eligible participants, 3) registration, 4) administrative selection, 5) competence test to get a talent pool. The two main factors that influence the recruitment of investigators are internally, the readiness of the INP General Crimes Directorate and externally the readiness of candidates to register and carry out tests.
INTEGRATION OF BLOCKCHAIN TECHNOLOGIES AND MACHINE LEARNING WITH DEEP ANALYSIS
Authors: Dziatkovskii Anton
Published: January 2023

The successful development of the digital economy, which we can observe since the advent of the internet, is closely related to progress in several "frontier technologies" (frontier technologies), among which the most important, according to the scientific community and international organizations, are such software-oriented technologies as blockchain, Big Data Analytics (Big Data), Artificial Intelligence (AI) and cloud Computing (Cloud Computing), as well as specialized machine-oriented equipment: 3D printers, internet of Things devices (Internet of things Things, IoT), automation and robotics. Significant progress in the application of these technologies contributes to the growth of production capabilities, labor productivity, and capital return of both digital companies and enterprises of the non-digital economy while transforming their established business models and principles of generating income and expenses of companies. This makes it necessary to study the above technologies in detail from the point of view of analyzing their essence, role, and potential for use in various spheres of economic life. Although the term "blockchain" has recently entered scientific and public use, the idea of the technology appeared in the late 1980s, namely in 1989. Lamport proposed "a model for achieving consensus on results in a network of computers, where computers or the network itself can be unreliable". In 2008, Satoshi Nakamoto proposed the concept of using a decentralized computer network to operate a P2P electronic money system. In the article "Bitcoin: a Peer-to-Peer Electronic Cash System" published on the internet, the innovator described the algorithm of functioning of the Bitcoin cryptocurrency as a completely independent electronic cash system from a single issue Center, which does not require the trust (mediation) of a third party, but relies on direct operations between the parties to the transaction, protected by cryptographic encryption.
UKRAINIAN PUBLIC PHILOSOPHY IN SEARCHING FOR A PUBLIC
Authors: Ovcharenko Svitlana
Published: January 2023

Purpose. The aim of the article is to analyze the state and development of public philosophizing practices in Ukraine in modern technological and socio-cultural conditions. Theoretical basis. The author proposes to proceed from the fact that the removal of philosophical thought is an act of social communication, which becomes a cultural event and has signs of performativity with its aesthetic characteristics. Based on this, the process of social functioning of philosophy can be considered not only as a set of ideas and concepts but also as a set of performative practices in public spaces that correlate with the relevant historical and cultural contexts. The concept of "public philosophy" is difficult to unambiguously define, especially in the formation of a new paradigmatic field for social communication in substantive and formal aspects. Originality. The article analyzes the process of self-awareness of tasks, content, and formats of public philosophy in the professional philosophical environment of Ukraine in the period 2014-2021 and formed a methodological position, which suggests outlining the phenomena and meanings of public philosophy to take into account both substantive and performative features. Conclusions. Analysis of the "public turn" in Ukrainian philosophy forms a new topic for research that should find meaning based on both the modern sociocultural reality of Ukraine and the prospects of general technological renewal of communication: 1) philosophy as a fundamental basis for forming a postdisciplinary paradigm of interaction areas of knowledge; 2) performative aspect of philosophical public communication; 3) the relationship between public and practical philosophy in the context of the analysis of cultural practices.

Published: January 2023

This study discusses the influence of the Code of Ethics and Code of Conduct for KPK personnel which includes 5 (five) basic values, namely: integrity, synergy, fairness, leadership, and professionalism towards preventing corrupt behavior among KPK employees. Integrity, synergy, fairness, and leadership are placed as independent/exogenous variables while professionalism is placed as a moderating variable. The research objective is to answer the formulation of the problem which includes 9 research questions. The research method uses a quantitative approach through SEM (Structural Equation Model) analysis. The number of samples was 321 people who were calculated based on the Slovin formula and were taken using a proportionate random sampling technique, in this case, the KPK employees who came from State Civil and Assigned Civil Servants. Variable operationalization uses indicators that have been formulated in the Code of Ethics and Code of Conduct for KPK Employees, namely as stated in Perdewas KPK Number 2 of 2021, and from various theories. From the results of the study, it was concluded that there is a positive and significant influence of Integrity, Synergy, and Leadership variables on Professionalism and Prevention of Corrupt Behavior among Employees at the KPK. The justice variable was found to have no significant effect. This means that if the quality of the three variables that have had this influence is improved, it will be followed by an increase in professionalism and prevention of corrupt behavior. Fundamental improvements are needed regarding aspects of justice, which include the creation of a conducive work environment and perceptions of fairness in the fulfillment of employee welfare to improve the variables of justice.

Published: January 2023

The present study is aimed at taking a deep look at the differences between digital native and digital immigrant lecturers’ strategies in doing online learning in higher education. Online teaching is the teaching carried out not physically face to face between students and lecturer, rather by the use of any internet platform in distance. Digital native lecturers are lecturers born in the era of knowing the growth of technology and very familiar and skilled of operating any technological media of teaching (in this research, for those lecturers born after 1980). Digital immigrant lecturers are lecturers born in the era when the technology was not yet grown and popular and they still maintain to use conventional media of teaching (those lecturers born before 1980). The objectives of the present study are (1) to investigate how digital native lecturer is different from digital immigrant lecturer in the stage of implementation in teaching online courses for higher education student? This includes the problems such as their perception toward teaching online course, what platform they use for teaching online course, how they use the platform to implement and evaluate the online course; (2) to examine how digital native lecturer is different from digital immigrant lecturer in the stage of obstacles in teaching online courses for higher education student; (3) to elaborate how digital native lecturer is different from digital immigrant lecturer in the stage of overcoming obstacles in teaching online courses for higher education student. The findings of the present study provides insight on the practice of online teaching by both digital native and digital immigrant lecturers in higher education, then provides insight on the obstacles and strategies for solving them. Mostly (80%) of all lecturers have positive perception toward online teaching; merely five (mixed male and female lecturers) out of 21 lecturers who have negative perceptions and those are only digital immigrant lecturers (born before 1980) from different departments. Only few digital immigrant lecturers have negative perception toward online teaching. There are no disparity (no significant difference) between digital immigrant lecturers and digital native lecturers in terms of obstacles they face in online teaching as well as in solving the obstacles. Considering that there are many positive things in the use of technology in online teaching; in this case technology can optimize the quality of teaching, this can be the basis for universities broadly to make policies about the percentage of online teaching in the post-pandemic era with applicable terms and conditions. With background insight and the gap in technology literacy between digital native and digital immigrant lecturers, universities need to routinely provide training on the use of various technologybased platforms that support the optimization of teaching.

Authors: Chalmers Jennifer
Published: January 2023

The purpose of this research was to thoroughly study the psychometric properties of the Love Bank Inventory (LBI) with married participants. The LBI is a 21-item Likert-type English survey developed to measure romantic love for a partner. Two studies were conducted with independent data sets (Study 1: n = 143; Study 2: n = 142) that represented 22- to 62-year-old heterosexual, nondyadic married respondents with multicultural citizenship. The results of the two studies provide support for (a) a single-factor model, (b) convergent validity with a positive correlation with the statement about romantic love (rs = .67 - .68) and construct criterion validity with a positive correlation with the Locke-Wallace Marital Adjustment Test (r = .76 - .80), (c) internal consistency of LBI statements (? = .95 - .96,), and (d) test-retest reliability (r = .88). These two studies provide support for the use of the LBI as a free tool to assess romantic love in marriage education development and applied settings.

Authors:   IAAS MSU, Moscow, Russia, BEKTIMIROVA Nadezhda N.
Published: January 2023

This article considers the results of local elections in Cambodia which took place on the 5th of June 2022. A key component of the electoral campaign of the ruing Cambodian People’s Party which significantly influenced its impressive result was the announcement regarding the forthcoming change in political elites and their rejuvenation. Hun Manet has been put forward as the prime ministerial candidate. The exact timing of this fundamental shift in political elites has so far not been confirmed. Among the opposition parties, the Candlelight Party, which took 20 percent of the votes, showed the best result. Some parties insisted on the idea of uniting efforts and creating some sort of common structure which would improve their chances of success for parliamentary elections. However, the Cambodian opposition does not have a strong experience of consolidated actions.

THE PEOPLE'S DEFENSE FORCES OF MYANMAR AND THE POSITION OF THE WEST
Authors:   Institute of oriental studies, Russian academy of sciences (MOSCOW), SIMONIYA Aida A.
Published: January 2023

The author raises the question: why the United States, the United Kingdom and the EU, condemning the military coup in Myanmar, criticizing the current military administration, announcing sanctions, adopting resolutions, calling for an end to violence and dialogue of the conflicting parties, in fact, only verbally support the fighters resistance in Myanmar, denying them real help, as is done in relation to other countries, in particular, Ukraine? Representatives of the West demonstrate concern over the current deep crisis in Myanmar, at the same time they do not officially recognize the parallel Government of National Unity formed from legitimately elected deputies − members of the National League for Democracy. The author gives several answers to this question, although he believes that one explanation is enough – this is the opportunistic approach of Western countries to the problem.

Published: January 2023

The article examines the nature of bilateral relations between Kingdom of Thailand and Laos. In Thailand, significantly superior in terms of economic development and standard of living, those relations are considered as senior-junior relationships. In Laos, as far as the country's national self-consciousness grows, they are considered equals. At the same time, Laos, very close to Thailand in ethno-confessional terms, accept from Thailand various forms of traditional patronage. Thus, thanks to soft power, Thailand has the opportunity to keep Laos in the orbit of its influence.

Knowledge Management’s Specific Means and Methods Considered within the Romanian Military Units
Authors: Pirsoi Teodora
Published: January 2023

Knowledge management (KM) is unquestionably one of the most promoted branches of scientific management. As the term itself suggests, this particular administrative model directs attention toward knowledge, understood as one of the most important resources within an organization. The main objectives of the current article are to discuss and analyze some of the most frequently proposed managerial means and methods of surpassing certain difficulties within military organizations from the region of Oltenia. The paper was conducted with the aim of evaluating the traditional techniques used to facilitate the implementation of KM within such organizations. The assessment was carried out based on the answers given to a specific questionnaire, which was addressed to the current or former workers of the military units within the counties of Dolj, Gorj, Olt, Vâlcea, and Mehedinți. The outcomes of the research suggest that one of the most efficient managerial techniques used in order to increase group cohesion and, thus, organizational productivity, is organizing teambuilding activities. Other managerial methods that a knowledge-based administrative model encourages are organizing constant informal group meetings or promoting post-factum analysis as a common manner of evaluating any experience. The conclusions revealed some quite strong connections established between the degree of success underlying a managerial model built on knowledge as the main resource and the proposed peculiar techniques used with the aim of improving the organizational goals and results.

The paper approaches the application of the Activity-Based Costing (ABC) calculation method within an accounting services company. The method is among the modern methods used in the calculation of the cost which takes into consideration a more cautious distribution of resources based on the activities that lead to the achievement of an objective. The purpose of the study is the distribution of costs to the groups of significant services performed by the accounting company: bookkeeping services, general accounting services, and the preparation of financial statements and analysis. The ABC method starts from the organization of the company by processes and activities and from a less subjective allocation of overheads compared to the traditional method.
Exploring Rising Income Inequality in the European Union - A Public Choice Approach
Authors: Negri Camelia
Published: January 2023

This paper aims to analyze the extent to which European Union (EU) member states succeed in diminishing income disparities using their quality of governance in the context of rising income inequality. By using the Data Envelopment Analysis (DEA) nonparametric method, the link between each country's efforts regarding their governance quality and the impact of these efforts on countering growing inequality was uncovered. The data used in this study were collected for the year 2020, for all 27 member states of the European Union. The main findings point out that, on average, EU countries are relatively inefficient, with only three countries achieving high levels of government performance, whose financial policies are reflected in reducing income inequalities, namely: Luxembourg, Cyprus, and Bulgaria. Furthermore, it was concluded that EU veteran states are relatively more effective than those that joined after 2004 in terms of eliminating income disparities through effective governance.
Investor’s Behaviour: A Conceptual Framework
Authors: Trifan Ruxandra
Published: January 2023

This article aims to provide a more comprehensive analysis of the investor’s behaviour. To do so, we first address the concept of individual behaviour which lacks a rigorous, precise definition that would be unanimously accepted. The multidimensional nature and complexity of human behaviour are approached from both a psychological and a financial point of view, by examining its relationship with the genetic structure, the psychic structure and the social environment. Secondly, we investigate the concepts of homo economicus and homo sapiens related to the traditional economic models, and to the behavioural finances approach, respectively, highlighting the “normality” of the investors, who cannot be limited to mathematical policy models. At the same time, we stress the importance of the evolution of homo economicus along with the constantly developing environment and the new challenges and changes faced by the financial markets.
The Causal Links between Trade Openness and FDI Inflows in Sri Lanka
Authors: Rathnayaka Mudiyanselage M.M. , Epuran G. , Tescasiu B.
Published: January 2023

The study examines the causal links between trade openness and FDI inflows in Sri Lanka from 1997 to 2019 using the ARDL test and Granger causality test. The results of the ARDL bound test indicate that an increase in trade openness does not affect FDI in the long run. However, short-run results indicated that an increase in trade openness attracts more FDI. The Granger causality test shows that Sri Lanka has a unidirectional causal relationship that runs from trade openness to FDI. The study suggests that the government should focus on long-term FDI target trade policies in order to improve the investment climate in Sri Lanka.

Published: January 2023

Green extraction methods present a perspective approach for the isolation of bioactive molecules. Together with an ecofriendly approach to extraction, there are many undervalued plants - a rich of source of prebiotics and phenolic compounds. Carlina acanthifolia L. roots possessed antimicrobial, anti-inflammatory, and anti-ulcer properties due to the diverse bioactive compounds in them. Detailed information about inulin-type fructan in its roots is still absent. The object of this work was to define inulin, sugars, and phenolic content, the antioxidant activity in the water, and 70 % ethanol extract resulting from ultrasound-assisted extraction (UAE) and pressure-liquid extraction (PLE). The results showed that the total fructans reached 12.6±0.2 g/100 g dw. Inulin was found in water extracts (6.82 g/100 g dw) in the prevalence of ultrasound-assisted extracts. Total phenolic content did to not exceed 15.25 mg GAE/g dw. Additionally, the antioxidant activities were in the range from 5.99 to 205.83 μM TE/g dw. In conclusion, water extracts from UAE demonstrated higher levels of bioactive compounds with antioxidantive properties, probably due to cavitation process. However, this study is the first detailed investigation for fructans and polyphenols content, as well as antioxidant activity of Carlina acanthifolia L. roots in extracts obtained by green methods. Therefore, this research enriched the information of bioactive compounds in Carlina acanthifolia L. roots.
Modelling Productivity in Extraction Operations by Simulations Based on GNSS Documented Data: An Example from Skidding Teak Wood In Thailand
Authors: Kaakkurivaara N. , Kaakkurivaara T. , Ketkaew C. , Sakulya T. , Borz S.A.
Published: January 2023

In Thailand, teak harvesting always includes skidding of tree-length stems from the landing to the log yard for further processing. When terrain does not set limitations for the machines to be used, skidding is carried out by farm tractors. In this study, data was collected from 10 work cycles of teak extraction to simulate the productivity of farm tractors. The GNSS data as speed and locations were used to extract operational distances and time consumption, as well as to support productivity simulation. For this, detailed measurements were done on the extracted stems to collect their diameters and lengths. For approximately six stems per load, the mean load size was 1.723 m3. The study found that mean productivity was 17.4 m3/h during the survey, where the mean extraction distance was 217 m. Our simulation presents productivity diagrams in relation to skidding distance. By simulation, we detected that reducing the full operational speed by 1 km/h would decrease productivity by 1 m3/h when the extraction distance is less than 100 m. Another observation was that even small reductions in load sizes have a remarkable effect on productivity over short distances. Until large-scale studies are to be done to evaluate productivity in relation to variations in load size and extraction distance, the results shown herein could stand as a basis for productivity assessments.

Authors: Rukomojnikov K.P. , Gilyazova T.A. , Sergeeva T.V. , Vasyankina S.V.
Published: January 2023

The results obtained in this article relate to the scientific and technological development of the timber industry. The main idea of the article is based on the possibility of concentrating several forest plots designated for felling with different percentages of cut components within a single cutting area. On the logging site created in this way, single main skidding and skidding trails were laid, allowing the entire range of logging operations to be carried out. The shape of such combined cutting areas can be a complex geometric figure. The purpose of this article is to improve existing methods and mathematical dependencies to justify the average skidding distance of timber when combining adjacent forest areas into a single cutting area. The article uses the methods of mathematical analysis, in particular, the methods of differential and integral calculus. The developed algorithm made it possible to create a unified methodological approach to find the average skidding distance, regardless of the shape of the cutting area. An important distinguishing characteristic of the created mathematical dependencies is that they can be used in cutting areas consisting of several forest plots characterized by different wood stocks. The forest areas included in the cutting area may differ in the presence of a branched structure of the main skidding and skidding trails. The results obtained can be used effectively by logging enterprises in substantiating the production rates and planning the work for future periods. As a result of using the obtained mathematical dependencies, it becomes possible to effectively place loading points and skidding trails on the territory of the cutting area.

Published: January 2023

The aim of this research is to develop and validate an experimental model testing method in the erhu instrument. The model analysis is dependent on the dynamic behavior of materials which results the relationships to be naturally excited due to the structure. There are three major factors which would directly affect the performance of erhu vibroacoustic: (1) string, (2) vibrating skin, and (3) wooden soundbox. However, the transducer mass effect is the significant impact factor in the membrane vibration measurement. The attention is focused on the erhu skin vibration modes by using the scanning laser method. The method for experimental mode shapes of erhu skin was notable in that the equipment assembled a loudspeaker, a signal point laser, and a scanning laser vibrometer. The mode shapes can be excited depending on the white noise with plane acoustic wave to push on the skin surface. The scanning laser method is content two types of laser doppler vibrometer for various purpose. The single point laser measured the driving point vibration as the reference in the center of the skin surface. The responses were measured by the scanning laser vibrometer with 276 measuring points on the surface. The results showed the vibroacoustic of erhu skin which the various mode shapes are dependent on the frequency diversifications. The mode shapes of the erhu skin can be characteristic into five vibroacoustic patterns by the various frequency ranges (20 to 5,000 Hz).  Obviously, the scanning laser method is a convenient and readily reproducible setup to evaluate in the erhu vibroacoustic properties. As an engineering application, the proposed method can be served as a fundamental tool when predicting or even suppressing the possible excitations associated with particular vibration modes in the mechanical designs of the instruments.
Effects of Wood Flour and Curing Temperature on Some Properties of the Polyurethane Foam Core in a Wood-Based Sandwich Panel
Authors: Sae-Ueng K. , Krause A. , Chotikhun A.
Published: January 2023

The objectives of this study were to examine the chemical, physical, and mechanical properties of polyurethane (PU) foam prepared with various wood flour contents and curing temperatures for use as a core layer in wood-based sandwich panels. The five alternative wood flour contents tested were 2, 4, 6, 8, 10, and 12%, and the alternative curing temperatures 100, 120, 140, and 160°C were studied with 10% wood flour content. The results showed that the cell size and density of the PU foam increased at wood contents above 6%, which reduced the compressive strength of the samples. It was also found for PU with 10% wood content that curing at 100 to 160°C caused a decrease in foam density by 50%, compared with PU foam cured under the standard conditions (i.e., at room temperature). SEM and cell size measurements show the anisotropy of PU foam and the increase of foam cell diameter when increasing the curing temperature from standard condition to 140°C. Consequently, the compressive strength and its specific value declined abruptly at elevated curing temperatures, starting from 100°C. These results suggest that elevated curing temperatures cause degradation of the properties of wood-filled PU foam, due to effects on foam cell structure.

The number of birds that die from diseases caused by aflatoxins in corn is the motivation for this study. The purpose of this research is to a) measure the success of aflatoxin treatment in the preharvest, post-harvest, and Innovative Reduction of Aflatoxin (IRA) processes, b) measure the effect of pre-harvest (PRE) and post-harvest (POST) handling on standard control maize (SQC) with IRA mediation. The test method used

Structural Equation Modeling (SEM) with the Partial Least Square (PLS) approach. Findings show that Innovative Reduction of Aflatoxin (IRA) is able to play a role as a mediation of activities in pre-harvest and post-harvest after continuous improvement is carried out in each of its activities. The originality of the research can be seen from the process of forming a corn aflatoxin control strategy as a practical recommendation for farmers in Indonesia.

In this paper, we offer a new generalization of the invo-clean ring that is called invo k-clean ring. Let 2 ≤ k ∈ ℕ }. Then a ring R is called invo k-clean if for each a ∈ R there exist v ∈ Inv(R) and e ∈ Pk(R) such that a = u + e. We obtain some properties of invo k-clean rings.
About some speeds of convergence to the constant of Euler
Authors: Vernescu Andrei
Published: January 2023

The speed of convergence of the classical sequence which defines the constant of Euler (or Euler-Mascheroni), γ = lim n→∞ γn = 0, 577215 . . . , where γn =(∑k=1n 1/k ) − ln n, was intensively studied. In 1983 I established in [14] one of the first two sided estimates of this speed, namely 1/2n+1 < γn−γ < 1/2n. Further several new sequences with a faster convergence are defined either by modifying the argument of the logarithm (De Temple, 1993, Negoi 1997, Ivan 2002) or by modifying the last term 1/n of the harmonic sum (Vernescu 1999). Now we give a systematic study of these speeds of convergence and especially of the last ones.

To obtain approximations of an unknown initial values there are considered arguments based on the adjoint differential system attached to the given differential system. Finally the Newton-Kantorovich iterations are regained.
Cattmul-Rom spline approach and the order of convergence of Green’s functional method for functional differential equations
Authors: Bica A.M. , Curila (Popescu) D.
Published: January 2023

The purpose of this work is to investigate the convergence properties of Green’s function method applied to boundary value problems for functional differential equations. Recently, involving Picard and Mann iterations, a Green’s function technique was developed (in Int. J. Computer Math. 95, no. 10 (2018) 1937-1949) for third order functional differential equations, but without specifying the order of convergence of the proposed method. In order to improve this aspect, here we establish the maximal order of convergence of Green’s function method applied to two-point boundary value problems associated to second and third order functional differential equations. In this context, by using suitable quadrature rule and appropriate spline interpolation procedure, the Picard iterations are approximated by a sequence of cubic splines on uniform mesh. Some numerical experiments are presented in order to test the theoretical results and to illustrate the accuracy of the method.
