Defining Technopreneurs’ Commercialization Research Process in the Emerging Thai Economy: Research for Constructing Grounded Theory
Authors: Phuthong Thadathibesra
Published: May 2023

This research aimed to 1) define sources of meaning in technopreneurs’ commercialization research process, 2) establish the common features of technopreneurs’ commercialization research process, and 3) construct a grounded theory of technopreneurs’ sources of meaning and commercialization research process. The study employed a qualitative ground theory approach to explain the phenomena and develop theoretical conclusions. Data was gathered through in-depth interviews with 15 technopreneurs using theoretical sampling. The interviews used open-ended questions, and the resulting data were analysed via analytic induction to define concepts and construct the grounded theory. The results indicated that technopreneurs elicited sources of meaning through the commercialization research process, which were categorized into three features of idea development with passion, integrated business model development, and innovative and technological business networking. The commercialization research process includes eight stages: 1) business opportunity assessment, 2) technopreneurial mindset and passion development, 3) technology assessment and exploitation, 4) co-research and application to new product development, 5) technopreneurship incubation and business networking, 6) business planning for innovation commercialization, 7) continuous product improvement, and 8) sustainable technopreneurship and development. Finally, this research constructed theoretical conclusions, discussing and suggesting approaches for improving technopreneurs’ commercialization research process and future research directions.

Published: May 2023

Higher education institutions use Learning Management System (LMS) to support and enhance the teaching and learning process. However, teaching and learning activities at Technical and Vocational Education and Training (TVET) institutions differ from non-TVET institutions, so the LMS is believed to be underutilized. This paper aims to investigate why LMS use in TVET is different from the non-TVET institutions. Additionally, this paper seeks to discover important factors that can help improve the acceptance of LMS at TVET institutions. Important factors are identified from a literature review study involving articles related to LMS and TVET published between 2019 and 2022. Seven domain experts in LMS at TVET institutions were interviewed for their opinions on the initial list of factors and performed the content validity assessment. Based on Lawshe’s content validity ratio, nine factors with 51 items have been identified. These nine factors are System Quality, Service Quality, Information Quality, Motivation, Self-Discipline, Practical Training, Intention to Use, User Satisfaction and Actual Use. This study also reveals new factors that can increase the acceptance of LMS in teaching and learning in TVET institutions. Findings can assist researchers, developers, and LMS stakeholders in understanding the use of LMS at TVET institutions to ensure online TVET teaching and learning effectiveness.

Published: May 2023

Predicting student performance in higher education based on students’ self-efficacy and learning behaviour data is challenging, because the data is changing with time. The potential of using continuous data which is collected weekly needs to be investigated to identify the effectiveness in making predictions of low-performing students. Therefore, this paper presents the analysis of continuous data using the Principal Component Analysis (PCA) and Support Vector Machine (SVM) for predicting student performance. Firstly, we proposed three patterns of the Principal Component (PC) scores to predict the trends of behaviour within a semester. Secondly, we present an analysis of using different combinations of time frames in predicting the performance using the SVM. The obtained results show that three behaviour patterns have been extracted from the Hotelling’s T² values calculated using the PC scores which were fluctuating, ascending, and descending. The use of different time frames using SVM shows different accuracy results in prediction. The use of continuous data indicates that certain data can be predicted at the early stage using multiple time frames.

Authors: Winarso Widodo , Udin Tamsik , Mulyana Asep
Published: May 2023

The purpose of this study was to examine the effectiveness of a religiosity-based psychoeducation program in reducing academic procrastination among students, based on the Big Five personality traits. The study utilized a one-group pretest-posttest design to analyze the impact of the religiosity-based psychoeducation program on academic procrastination. The academic procrastination questionnaire and the Big Five personality traits scale were used for data collection. Data analysis was conducted using Dependent sample t-test and two-way ANOVA to determine the differences in the level of reduction in academic procrastination based on personality traits. The study found that the application of the religiosity-based psychoeducation program was effective in reducing academic procrastination among students, with significant decreases observed in both State Islamic and Private Universities. Additionally, differences were observed in the level of reduction in academic procrastination based on the Big Five personality traits, with extraversion and neuroticism decreasing drastically compared to the other three traits. Religiosity-based psychoeducation programs can be an effective approach in reducing academic procrastination among students, especially when combined with lectures or religious activities on campus/institutions. The findings of this study suggest that addressing procrastination based on personality traits can improve the effectiveness of interventions aimed at reducing academic procrastination. This study has practical implications for educators and academic institutions seeking to address academic procrastination among students. By tailoring interventions to address personality traits and incorporating religiosity-based psychoeducation programs, educators can effectively reduce academic procrastination among students.
Association Between Dietary Quality, Socioeconomic Level, Body Mass Index, and Age in Adolescents (Eastern Algeria): A Cross-sectional Study
Authors: Karoune Rabiâa , Colette Dahel-Mekhancha Corinne
Published: May 2023

Aim: This article aims to evaluate the quality of adolescents’ diet in Constantine (Eastern Algeria) and investigate factors associated with this quality: Socio-economic Level (SEL), nutritional status (BMI), and age.
Methods: A cross-sectional survey was conducted in Constantine (Eastern Algeria) in 2019 with 1126 adolescents (aged 11–19 years). The dietary data were collected by a 24-hr recall. The diet quality was assessed by a diet diversity score (DDS) calculated for 9 food groups (DDS above the mean reflects a diversified diet) and a mean adequacy ratio (MAR) calculated for 12 nutrients. MAR’s cut-off value was "one." Weight and height were measured, and BMI was interpreted according to the World Health Organization reference values. The SEL was assessed using a socioeconomic classification score (SECS) according to parents' education level, profession, and other household information.
Results: The mean DDS was 3.97 ± 1.25. It was shifted to the lowest values compared to the theoretical mean value (4.5). Insufficient scores (DDS ≤4.5) were found in 65.0% of subjects. The mean MAR was 0.59 ± 0.20 and values <1 represented 79.1%. A significant negative correlation was recorded between age and MAR (r = −15%; P < 0.0001), and a positive correlation was found between it and SECS (r = 18%; p < 0.0001). BMI is inversely and significantly associated with MAR (r = −9.9%; P = 0.0009).
Conclusion: In addition to highlighting a low diversity and a poor adequacy with nutritional recommendations among adolescents in Algeria, this study underlines the significant effect of age, BMI, and socioeconomic level on the quality of diet.
Keywords: dietary diversity score (DDS), mean adequacy ratio (MAR), BMI, socioeconomic level, adolescents

Challenging Issues of Knowledge of a Good Faith Acquirer on the Absence of Authorities of the Transferor
Authors:   Attorney at YUST Law Firm, Leading Expert of the Institute of Administrative Regulation Issues of the Higher School of Economics, PhD (Law), Malbin Dmitry A.
Published: May 2023

Article 302 of the Civil Code of the Russian Federation protects the acquirer, who did not know and could not know about the alienator’s illegality when acquiring the thing. Knowledge of the rights of the alienator to the thing is one of the conditions for the protection of the acquirer. At the same time, the question of the volume and content of the acquirer’s knowledge for qualifying it as conscientious is debatable. The article proposes to proceed from the fact that in order to recognize the acquirer as good faith, it is sufficient to have no doubts about the legal basis for acquiring the rights of the alienator to the thing. The imposition on the acquirer of the burden of verifying the powers of the person from whom the alienator acquired the thing is an excessive burden for an ordinary participant in civil turnover. With regard to real estate, the acquirer must be considered good faith if the alienator’s right is registered in the state register of real estate, unless the acquirer is aware of the justified claims of third parties in relation to the real estate object.

Authors:   Professor of the Department of Commercial Law, Academic Supervisor of the Lawyer in the Financial Market Sector (Financial Lawyer) Primary Educational Program of Graduate Studies of the Saint Petersburg State University, LL.D., Petrov Dmitry A.
Published: May 2023

Bidding is a competitive way of choosing a counterparty and one of the factors in the formation of a competitive environment. Organized auctions presuppose the presence of a specialized intermediary, and their conduct is conditioned by a number of organizational conditions. The conditions for the admission of goods to trading and the special procedure for concluding contracts at organized auctions act as an institutional restriction of exchange trading and predetermine the fact that not every product is able to be sold on the exchange (recognized as an exchange commodity). Exchange trading pursues the goal of organizing trading activities and, as a secondary effect, forms stock prices (stock quotes, stock indices). The obligation of the seller (manufacturer) to sell part of the goods on the stock exchange (the mechanism of administrative compulsion to sell goods on the stock exchange) is aimed at forming national market price indicators for key groups of goods for regulatory purposes, and not the development of competition as such.
Restitution on Reversal of Judgment When the Defendant Was Deprived of Ownership of Specific Property in the Course of Execution of a Money Collection Judgment
Authors:   Teaching Assistant of the Department of Civil Procedure of the Saint Petersburg State University, Torgashev Aleksandr V.
Published: May 2023

The article justifies the position that if, as a result of the execution of the court decision on the recovery of funds, the defendant was deprived of his property, and in the future this decision was canceled and the claim was refused, then the defendant can protect the violated right by filing a replevin claim against the illegal possessor. If this claim is satisfied, the former illegal possessor has the right to apply for damages to the plaintiff (eviction). The overturning the execution of judgment in this situation does not apply. The author believes that the institution of the overturning the execution of judgment in the form of compensation for the actual value of the individually defined property collected is possible only if this thing cannot be vindicated from the illegal owner. In this case, the defendant has a requirement to recover unjust enrichment against the plaintiff. If there are causes for presenting a vindication claim, the defendant shall not be entitled to declare other methods and means of protecting the violated right except for the vindication claim. The overturning the execution of judgment in the form of a recovery of an individually defined property from the plaintiff is impossible in any case — the plaintiff is not its owner, therefore the court's decision of overturning the execution of judgment will be unenforceable.

The author compares the concepts of ‘”circulation of medicines” and “pharmaceutical activity”. The main content of the text is an analysis of the responsibility of manufacturers for damage caused to the health of citizens by substandard, falsified medicines. The relevance lies in the fact that now, during the pandemic, special attention is being paid to new medicines. Due to the fact that they are a special type of product, they are subject to strict requirements for quality, safety and effectiveness, compliance with which also falls on manufacturers of medicines, which once again underlines the need for clearly defined responsibility of manufacturers of medicines. In conclusion, the author suggests possible changes in the legislation on the responsibility of the manufacturer of medicines.

Authors:   University of Jordan, Safwan MF , Amayreh MA ,   Al-Balqa Applied University
Published: May 2023

As a result of different human activities in different industrial and agricultural fields, heavy metal toxicity increases day by day. Some of these metals pose a severe threat to the human body, even if these are present in low quantities. These metals are therefore, referred as human carcinogens according to the United States of Environmental Protection Agency (USEPA) because they damage the organs in the human body as a result of their non-degradable nature, ability to accumulate, and having prolonged biological half-lives. There are many routes through which toxic heavy metals can enter the human body, including polluted water and soil and dietary intake. New food products have been widely spread out such as instant soup noodle products which are manufactured from different types of vegetables and spices and subjected to industrial processes. As a result, contaminations by some heavy metals is possible. The objective of this study was to assess the content of Manganese (Mn), Chromium (Cr), Cadmium (Cd) and lead (Pb) in different branded chicken stock powder from Jordanian market. The analytical method was based on the digestion of different types of chicken stock samples prior to their Atomic Absorption Spectrometry analysis. The selected heavy metal concentrations ranged from 0.0407 to 1.08, 0.0211 to 0.592, 0.0134 to 0.0923 and 0.227 to 0.645 mg/kg for Mn, Cr, Cd and Pb, respectively. The maximum levels of Pb and Cd were detected in different brands of powdered soup products. The results found were within the accepted levels compared to food samples from reported research. In order to assess the health effects of the selected heavy metals, a scientific survey was performed on a group of people to assess the daily intake of the studied soup products. As a result, Health Risk Assessment (HRA) was evaluated from the estimated daily intake (EDI) of metals from the selected food samples. The obtained results showed that the selected food samples are quite safe and healthy according to the maximum recommended metal levels taken by humans.

Продуктивная толща Хотынецкого месторождения состоит из трех пачек, основными полезными компонентами которых являются минералы группы цеолита, опал-кристобалита и смектита. Их содержание достигает 80 %. Образование месторождения происходило в три этапа и связано с первичным накоплением кремнезема в прибрежных морских водах, сносом терригенного глинистого материала с близлежащей суши, дальнейшим уплотнением и переработкой накопленного материала на стадии диагенеза. Образование клиноптиллолита связано с повышением рН и растворением опал-кристобалитового и глинистого материала в результате вторичного воздействия низкотемпературных глубинных растворов. Проведенные эксперименты показали, что данное сырье обладает высокими сорбционными характеристиками по отношению к цезию и меди и может применяться в качестве компонента сорбционных смесей и барьеров для очистки загрязненных вод.

Relevance. One of the main tasks in predicting a geological section is the task of determining the type of the section and mapping types over the area under study, as well as assessing the absorbing and dispersive properties of geological media. To solve these problems, specialized software-algorithmic complexes for processing and interpreting seismic data are currently widely used. In most modern complexes for forecasting a geological section, the information extracted from the kinematic and dynamic characteristics of seismic waves is used. Based on the information received and the data on the geophysical survey of wells, ideas are formed about the material composition of sediments, the presence of productive strata in the study area. This approach made it possible in a number of regions of Russia, including Western Siberia, to obtain interesting and important results related to the discovery of productive sedimentary strata and the assessment of their oil and gas content, which was confirmed by practice. At the same time, the results of practical activities have shown that when conducting studies of many areas, there are areas where the percentage of identifying false anomalies in geological environments and making erroneous decisions in the forecast is still quite large. This is due, among other things, to the fact that in the analysis of the recorded seismic field, for predicting geological section, the energy characteristics of the reflected waves are mainly used, and changes in the phase spectra are practically not taken into account. Thus, the integrated use of the characteristics of reflected seismic waves (amplitude and phase) in the prediction of a geological section is a very urgent task. The aim of the work is to carry out phase-energy analysis for various models of seismic fields based on the method of phase-frequency deconvolution for predicting the geological section. Methods: computational experiment, inverse filtering, discrete Fourier transform. Results. The authors developed the algorithm for phase-energy analysis of seismic waves, which is based on the results of phase-frequency deconvolution. The algorithm was studied on various models of geological environments, and phase-energy sections were constructed, which make it possible to identify zones with anomalously low energy values for subsequent oil and gas potential diagnostics. The paper introduces the example of constructing a phase-energy section based on real data in the interval of Upper Jurassic deposits.

The relevance of the work is caused by the need to replenish the mineral resource base of gold on the basis of comprehensive information obtained recently using a modern analytical base. Purpose: to study the mineralogical composition of samples of the placer deposit of the river Zaslonka (Gornaya Shoria). Methods: mineralogical studies, crystal morphology, X-ray spectral analysis, scanning electron microscopy. Object: samples of concentrates from the alluvial gold deposit of the Zaslonka river (Gornaya Shoria). Results. The authors carried out the study of the mineralogical composition, including the morphology of gold particles, samples of black concentrates on the MBS-10 binocular microscope and OLYMPUS SZX10 stereomicroscope, and slags after gold melting during the preparation of doré alloy on a Hitachi S-3400N scanning electron microscope. Photomicrographs of various types of gold particles and other minerals were taken. As a result of the research, it was found that the vast majority of gold particles belong to very small (68,71 %), as well as to small (14,69 %) and thin (12,47 %) size classes. Gold concentrates, after enrichment on a flotation table, are weakly radioactive due, apparently, to a thin dissemination of Th-U-containing minerals, which is confirmed by the study of slags on an electron microscope after melting gold during the production of doré alloy, where uranothorite, zircon and gold are found in the form of granular spherules. There are, apparently, three sources of gold entering the placer: 1) gold in the «shirt», covered with dark gray, almost black dense films, which is older gold and probably has a more distant source of drift; 2) gold of medium degree of roundness – flattened and lumpy golden-, dull-yellow and silvery-yellow in color, the sources of formation of which were medium-temperature and medium-distant quartz veins of the area; 3) unrounded golden-yellow gold, formed from nearby quartz weakly gold-bearing veins. The poor mineralogical composition of concentrates (and the almost absence of oxidized sulfide minerals, except for pyrite) indicates the presence of low-sulfide medium-temperature quartz veins with a low content of fine gold in primary ores.

El tema de la muerte es de importancia crucial para la comprensión del Antiguo Perú, pero los estudios no cuentan con una base de datos que sea apropiada ni se ha logrado elaborar un marco teórico propio.
¿Dónde están los restos óseos humanos del Periodo Pleistoceno Tardío? Problemas y perspectivas en la búsqueda de los primeros americanos
Authors: Dillehay Tom D.
Published: May 2023

En Sudamérica se conocen pocos restos óseos humanos confiables que supuestamente pertenecieron al Pleistoceno Tardío (antes de 10.000 A.P.). Todos ellos tienen problemas de contexto, asociación y/o fechado radiocarbónico. Lo mismo ocurre con el registro humano temprano de Norteamérica. Este problema se discute en términos de 1) visibilidad arqueológica y muestreo, 2) tendencias de estudio variables que afectan el registro, 3) patrones funerarios de los grupos de cazadores-recolectores tempranos que eluden el estudio arqueológico, y 4) soluciones posibles para resolver el problema.

Authors: Zapata Julinho
Published: May 2023

El sitio de Batan Urqu, ubicado en el valle de Huaro, provincia de Quispicanchis, Cusco, fue ocupado continuamente desde el periodo Formativo hasta la época del contacto europeo. Las excavaciones realizadas permitieron revelar que durante el Horizonte Medio se construyó un conjunto de edificios y estructuras de uso funerario en un espacio rectangular enmarcado por una muralla. Se proporcionan los datos obtenidos en las excavaciones en el complejo funerario wari llevadas a cabo por el autor entre agosto y octubre de 1992. Se describen la arquitectura y la organización espacial de las estructuras funerarias encontradas, posición de los individuos y los objetos asociados. Finalmente se ofrece una serie de observaciones sobre el patrón funerario y se proponen perspectivas para los análisis de vestigios culturales que en la actualidad se llevan a cabo.

Los restos humanos más tempranos del norte del Perú: balance y proyecciones
Authors: Briceño Jesús , Millones Mario
Published: May 2023

De manera genérica, la prehistoria americana ha mantenido fuera de su discurso a los restos de sus propios protagonistas. Semejante afirmación adquiere sentido si observamos la confección de esta historia pasada y aceptamos una cierta indiferencia pactada hacia los restos óseos. El norte peruano resulta un buen ejemplo y compromiso de intereses encontrados. Con este trabajo se busca cómo entender esta ausencia, encontrar los cuerpos "ausentes" y finalmente integrarlos al acervo de los materiales de estos primeros grupos humanos.
