Authors: Aryandari Citra , Siahaya Karel Martinus , Hazmi Fariz Al
Published: June 2023

The presence of Toki Batu music in Ulahahan Village as a cultural product cannot be separated from the musical narrative of the Maluku people, which has been part of social and cultural life since ancient times. This study aims to explain the concept of inclusiveness within the group and its functional role in society as an inclusive music community. The research method uses a descriptive qualitative with an ethnographic approach. Data collection techniques were carried out through observation, semi-structured interviews, and documentation. The study results explain that the concept of inclusiveness in the Ulahahan Babatu Orchestra community lies in membership open to people from various backgrounds, both children and adults. The Community also does not provide special requirements to be able to join the group because Toki Batu’s music belongs to the Community, and anyone should be able to contribute. The leadership style used is based on local culture by adopting respect for elders. As a result, the leader is someone who is older and more experienced in community management rather than someone who has mastered music. Functionally the role of the Toki Batu music community revives community creativity and influences collectively in various fields such as recreational, educational, communication and religious facilities.

Authors: Sahid Nur , Junaidi Junaidi , Iswantara Nur
Published: June 2023

This study aims to analyze the meaning of signs related to political conflict between characters in sineprak “Satru Ing Ngepal” (SIN). The political conflicts between these figures will be analyzed for their meaning by relating them to the social-historical context of Indonesia in the New Order and Reformation Eras. The research uses a theatrical semiotic theory approach, dividing theatrical performances into 13 sign systems. Signs related to political conflict between figures will be analyzed denotatively and connotatively. The content analysis method from Kriipendorf was used to analyze the data. The results of this study indicate that Senopati’s political conflict with Mangir semiotically refers to the meaning of the political conflict between the New Order and Reform rulers and the opposition. The enmity between Senopati, Juru Mertani, and Mangir refers to the meaning of the conflict between Wiranto and Prabowo Subianto. Pembayun’s marriage to Mangir means Prabowo Subianto joining President Jokowi’s government for 2019-2024. Pembayun’s courage to fight for Mataram peace with Mangir’s fief land refers to RA Kartini’s emancipation.

An analysis of technologies that allow creating microrelief structures on the surface of sapphire substrates has been carried out. It is shown that the most effective method of forming relief structures with submicron dimensions is ion beam   etching through a protective mask formed by photolithography. The main problems in creating a microrelief on the surface of sapphire substrates are the removal of static electric charge in the process of ion beam  etching of the substrates, as well as obtaining a protective mask with windows of specified sizes, through which etching of the sapphire substrate is performed.

Published: June 2023

This work attempts to replace the sandwich core's traditional shape and material with a cellular pattern, where the cells have a regular shape, distribution, and size. The contribution of this paper is to design two structures, one open-celled and the other closed, and to evaluate the performance of sandwich plates with lattice cell core as it is used for many industrial applications, particularly in automobile engineering. The new theoretical formulations are constructed for two structures to find the free vibration characteristics. The results of the new design are compared with the traditional shape. Derivation of equations to predict mechanical properties based on relative density with the chosen shapes, specific vibration equation of three-layer sandwich plate, and substitution by equation using excel sheet. Results are promising, and the effectiveness of cellular pattern theoretical analysis estimation. Limitations and error rates for the mechanical properties come through the empirical equations, and their ratio to the relative density values are higher depending on the behavior of the core material. Findings reveal, with open cell decrease in modulus of elasticity by (PLA: -90.4%) and (TPU: -90.4%), increases natural frequency by (PLA: 44.5%) and (TPU: 46.4%), as for closed-cell decreases in the modulus of elasticity by (PLA: -66.9%) and (TPU: -64.4%), increases natural frequency by (PLA: 36%) and (TPU: 37.7%). Converting a solid substance or replacing a foam form with a cellular pattern is one way to better performance and save weight through the selected cell pattern in absorbing the energy of the vibration wave.
Structural, morphological and photocatalytic properties of nanostructured TiO2/AgI photocatalyst

Published: June 2023

Nanostructured TiO2/AgI photocatalyst under the action of ultraviolet or visible electromagnetic radiation effectively neutralizes organic pollutants in the aqueous environment. It is a nanostructure in which micro- and small mesopores of anatase TiO2 are filled with silver iodide in the superionic state. The content of the α-AgI ion-conducting phase in the volume of ТіО2 pores can be ~20 wt %.

To obtain a photocatalyst, titanium dioxide is synthesized by the sol-gel method, using a titanium aquacomplex solution [Ti(OH2)6]3+•3Cl- and a Na2CО3 modifier additive as a precursor. The modifying additive during synthesis ensures the fixation of =О2СО carbonate groups on the surface of oxide material particles. The presence of these groups leads to an increase in both the pore volume and the specific surface area of ТіО2. The specific surface area of carbonized titanium dioxide is 368 m2•g-1, the pore volume is 0.28 cm3•g-1, and their size is 0.9-4.5 nm.

To fill the micro- and small mesopores of TiO2 with the superionic α-AgI phase, Ag+ cations are first adsorbed from the AgNO3 solution on the titanium dioxide surface, and then the oxide material is contacted with the KI solution.

Compared to the Evonik P25-TiO2 photocatalyst, the nanostructured TiO2/AgI photocatalyst demonstrates a significantly higher efficiency of photodegradation of organic dyes Congo Red and Methyl Orange in visible and ultraviolet radiation. The most active ТіО2/40AgI sample achieved complete degradation of the CR dye in 6 minutes of UV irradiation, while the efficiency of commercial Р25-TiO2 over the same time was only 42%.
La publicità nei documenti paleo-babilonesi di alienazioni immobiliari
Authors: Simonetti Cristina
Published: June 2023

RiassuntoLa pubblicità ha lo scopo di rendere possibile la conoscenza di atti o eventi produttivi di conseguenze giuridiche a chiunque ne abbia desiderio. Tale scopo risulta particolarmente importante nell’ambito delle alienazioni immobiliari, per permettere all’acquirente di conoscere la situazione giuridica di ciò che andrà ad acquistare. Nel periodo paleo-babilonese gli elementi idonei a tale scopo sono anche requisiti formali: la presenza dei testimoni (tra i quali possono annoverarsi anche pubblici ufficiali) e la stesura di un documento scritto e sigillato. Questi elementi porterebbero a pensare che nel periodo antico-babilonese citroveremmo in uno stadio già avanzato della pubblicità, in cui essa è dettata dalla necessità di fornire una“certezza per i contraenti e per i terzi”, ma anche da quella di “smobilizzo dei beni, attraverso la costituzione di titoli formali, più rapidamente circolanti”.Parole chiave: Pubblicità, alienazioni immobiliari, testimoni, documenti scritti e sigillati.AbstractThe publicity has the aim of making possible the knowledge of acts or events, which produce legal effects, to anyone in desire. This aim is especially important for the alienation of real estates, to enable the buyer to know the legal status of what he wishes to buy. In Old Babylonian period the proper instruments for the publicity were also formal requirements, i.e. the presence of witnesses (sometimes also officers, and often they were neighbors) and the drawing up of a written, and also sealed, document. These elements could mean that, during the Old Babylonian period, publicity was in an advanced stage of development, where it provides certainty for the contracting and third parties, but it promotes also the sale of real estate producing formal titles, that were more suitable for economic circulation.Keywords: Publicity, alienation of real estates, witnesses, written and sealed documents.

Woven hybrid composites: Water absorption and thickness swelling behaviors
Authors: Abdul Khalil H. P. S. , Jawaid M. , Abu Bakar A.
Published: June 2023

Oil palm empty fruit bunches (EFB)/woven jute fibres (Jw) reinforced epoxy hybrid composites were prepared by hand lay-up technique by keeping the EFB/ woven jute fibre weight ratios constant, i.e. 4:1. By combining oil palm EFB and woven jute fibre, it is possible to take advantage of both fibres while at the same time suppressing their less desirable qualities. These hybrids provide a new type of sandwich structure with a good skin-core adhesion and the potential for their applications as cost-effective sandwich construction. The effect of the layering pattern on the water absorption and thickness swelling of the hybrid composites was studied. It was observed that water diffusion occurred in the composites, depending on the fibre type as well as the layering pattern. EFB fibre composites exhibited maximum water absorption during the whole duration of immersion. The hybridization of oil palm EFB composites with woven jute fibre showed beneficial effects on both the water absorption and thickness swelling by improving fibre/matrix bonding.
Anhydride modification of cultivated kenaf bast fibers: Morphological, spectroscopic, and thermal studies
Authors: Abdul Khalil H. P. S. , Suraya N. L.
Published: June 2023

Kenaf bast fiber was chemically modified by using propionic and succinic anhydrides. Five retention times were compared: 30, 60, 120, 180, and 240 minutes at 100°C. Confirmation of anhydride modification was established by the weight percent gain (WPG) and was further confirmed by Fourier Transform Infra-Red (FT-IR) spectroscopy. Based on WPG, succinylated fibers exhibited higher WPG than propionylated fibers. The results of WPG for both succinylated and propionylated fibers showed that 180 minutes was an optimum time for modification, yielding the highest WPG. The thermal stability of modified fibers was characterized with Thermal Gravimetric Analysis (TGA). Succinylated fibers showed better thermal stability than propionylated fibers. Anhydride modification also enhanced the fiber smoothness, as demonstrated by Scanning Electron Microscopy (SEM) analysis. Succinylated fibers showed a much smoother surface as compared to propionylated fibers and untreated fibers. Anhydride modification significantly decreased the contact angle of kenaf bast fibers, thus imparting good adhesion characteristics to the fibers.

The experiences of learning self-regulation in distance education / Iskustva samoregulacije učenja u nastavi na daljinu
Authors: Šimić Šašić Slavica
Published: June 2023

Abstract The aim of the research was to examine the experiences of learning self-regulation and the attitude towards distance learning of the students in the upper grades of elementary schools and in high schools. The research included 1463 students from eight counties throughout the Republic of Croatia. The data were collected by using the Sociodemographic Data Questionnaire, the Scale of Attitudes about Distance Education and the Scale of Components of Self-Regulated Learning. The results showed the students’ moderately negative attitude towards distance learning, the moderately to highly explicit components of proactive self-regulation, the slightly lower components of defensive self-regulation, and very good school success. Differences in the attitude towards distance learning, the components of learning self-regulation and school success were determined with regard to the type of school, the student gender and place of residence. The learning of elementary school students in distance education is more self-regulated than the one in traditional classes. It was also determined that the components of learning self-regulation and the time spent in classes were the significant predictors of school success in distance learning.Key words: distance learning; self-regulation of learning; attitudes towards distance learning---Sažetak Cilj istraživanja bio je ispitati iskustva samoregulacije učenja i stav prema nastavi na daljinu učenika viših razreda osnovne i učenika srednje škole.

Researching the future expectations of sports sciences students
Authors: Turhan Fatih Harun , Canpolat Burak
Published: June 2023

Background and Study Aim. As the field of sports science continues to evolve rapidly, understanding students' aspirations is crucial for adapting educational programs accordingly. Furthermore, gaining insights into their future expectations can aid in addressing emerging trends and demands within the sports industry. The aim of the research is to examine how the future expectations of sports science students change at the end of their education life.
Material and Methods. The study focused on sports science students in Turkey, with a sample size of 130 students selected randomly. These students willingly participated in the research, and their pre-test and post-test scores were compared using a standardized scale to evaluate changes in their perceptions and expectations. The collected data were analyzed using the SPSS program. To examine potential differences among variables within the research group, the Man Whitney U test was utilized for dependent groups, while the Kruskal Wallis H test was applied to assess multiple differences between groups. A significance level of p<0.05 was established.
Results. The research revealed a significant difference in the pre-test results solely based on the educational status of the sports science students' mothers and fathers. Moreover, notable variations were observed in the average differences between pre-test and post-test scores concerning the students' departments and age. However, no significant differences were found in the future expectations of sports science students when considering gender, age, department, and income status variables. Notably, there was a significant difference favoring undergraduate students in terms of their mother's and father's education status variables. Furthermore, the mean scores of the pre-test and post-test demonstrated a significant difference between the age groups of 17-18 and those aged 21 and above. Additionally, significant differences were observed between students in the "Sports Management" department and those in the "Coaching" department, favoring the latter.
Conclusions. The study emphasizes that gender, age, department, and income status did not significantly impact the future expectations of sports science students. However, it is crucial to address the educational needs of undergraduate students and the variations in scores among different age groups and departments to better cater to their career aspirations and development..
Relationship between obesity, insulin resistance and cell membrane properties
Authors:   Higher Institute of Nursing Professions and Health Techniques, Rabat, Morocco, Ahyayauch Hasna
Published: June 2023

Introduction and aim. The obesity is one of the greatest public health problems in developing countries and it is a triggering factor for diabetes associated with insulin resistance. The importance of cell membrane lipids as essential regulators of insulin resistance, since changes in the dynamic properties of the cell membrane (e.g., membrane fluidity), could be one of the events by which obesity affects insulin sensitivity. Thus, the insulin resistance may not only be a cause but also a consequence of lipid disorders such as dyslipidemia and/or cell membrane phospholipid composition change. The modification of plasma membrane lipid composition can change membrane biophysical properties and thus influencing protein-lipid interactions, enzymatic activity and regulation of surface receptors. Alterations in the lipid composition modify the fluidity of plasma membranes and the expression of membrane functions, such as receptor binding and enzyme activities. This review summarizes the current knowledge on the effects of the modulation of plasma membrane lipid composition and membrane fluidity in the functionality of membrane proteins involved in insulin activity, including the insulin receptor, glucose transport and Na + /K + ATPase and, in turn, the key features of the metabolic syndrome. Material and methods. References for that article were found through PubMed and Google Scholar, using terms: “obesity”, “insulin resistance” and “membrane properties”. The research was limited to abstracts and available full-text articles. Analysis of the literature. There is a strong relationship between dietary lipids, membrane lipid profiles and insulin resistance. The changes in the dynamic properties of the cell membrane (e.g., membrane fluidity), could be one of the events by which obesity affects insulin sensitivity. The modification of plasma membrane lipid composition can change membrane biophysical properties and thus influencing protein–lipid interactions, enzymatic activity, and regulation of surface receptors. Modifications of membrane phospholipid composition could have a role in the insulin action by altering membrane fluidity and, as a consequence, the insulin signaling pathway. Conclusion. As conclusion the membrane-lipid therapy approach can be used to treat important pathologies such as obesity and many others diseases such as : cancer, cardiovascular pathologies, neurodegenerative processes, obesity, metabolic disorders, inflammation, and infectious and autoimmune diseases. This pharmacological strategy aims to regulate cell functions by influencing lipid organization and membrane fluidity, inducing a concomitant modulation of membrane protein localization and activity which might serve to reverse the pathological state. Through this review we suggest an in-depth analysis of the membrane lipid therapy field, especially its molecular bases and its relevance to the development of innovative therapeutic approaches.

Between Geographical Sameness and Historical Selfhood: Identity of a Historical Community in Paul Ricoeur’s Philosophy
Authors: Kumorek Michał
Published: June 2023

The issue of the identity of communities considered in a historical context brings many problems. The question of community identity is one of many challenges facing historians. It is subject to a multi-sided debate between extreme positions that seek a hard core of identity, and those that postulate a nomadic identity or deny it any meaning at all. Concerning the thought of Paul Ricoeur, the article will hypothesize that community identity can be considered between the poles of geographical sameness and historical selfhood, based on the model of demography and the model of collective memory. These models relate to the basic philosophical criteria of identity, and allow historians to refer to the multiplicity of aspects that fall within the geographical and historical criteria. By exploring these aspects in a web of interdependence, historians resemble narrators of a novel, who do not create a predictable plot but consider contradictions, twists, and conflicts. Thus, the work of historians acquires an ethical dimension, which is free from influence on the formation of the identity of the community to which they also belong.
„Gigantomachia peri tes ousias” i jej rezultaty. Czy analizy Platona można nazywać „ukrytą fenomenologią”?
Authors: Rycyk Konrad Dydak
Published: June 2023

Obecny w dialogu Sofista (246a i nast.) motyw walki gigantów (γιγαντομαχία) nie jest tylko zręcznym literackim zabiegiem ożywienia i udramatyzowania prowadzonej w dialogu dyskusji, ani też próbą uzupełnienia czy podparcia argumentu treścią dawnego mitu. Nie jest też emblematem tego, jakoby myślenie greckie porzuciło mit. Przeciwnie. Przejście od mythos do logos nie jest porzuceniem pierwszego, a raczej jego wyjaśnieniem i właściwym przedłożeniem. Wydaje się więc, że Platon przywołując ów mityczny obraz i stwierdzając, że wszystkie dotychczasowe filozoficzne spory to nic innego, jak walka gigantów na temat bycia (γιγαντομαχία περὶ τῆς οὐσίας), czyni to z premedytacją. Jakie są zatem faktyczne powody owej walki i jak rozumieć casus belli – dlaczego toczy się ona około bycia (περὶ τῆς οὐσίας). Dlaczego właśnie to, a nie coś innego, jest przedmiotem tego – co do sedna problemu – „gigantycznego” sporu? Zaproponowane przez Platona rozwiązanie owego sporu, polegające na podaniu największego ustalenia (ἐπιστήμη μεγίστη) dotyczącego idei będącego (τοῦ ὄντος ἰδέα) i określeniu jego znaków – postaci, jest istotne nie tylko z powodów historycznych i merytorycznych. Czy zatem biorąc pod uwagę metodę rozwiązania owego sporu i jego specyficzny rezultat można – w ślad za pytaniem postawionym w tytule – nazwać analizy Platona jakąś ukrytą fenomenologią? Czy w końcu samą zasadę uczestniczenia (τὸ μετέχειν) można rozumieć jako zasadę metafizyczną, której eksplikacja wymaga narzędzi fenomenologicznych?

Every day, doctors are faced with severe patients with various diseases, which is aggravated due to comorbidities. However, the management of such patients is complicated due to severe surgical pathologies, the treatment of which involves exclusively surgical intervention. The case describes a patient with critical aortic valve stenosis, hemodynamically significant coronary stenosis, metabolic and hematological disorders, as well as respiratory pathology. In order to achieve an optimal result, the patient’s diabetes therapy was adjusted, specific therapy for secondary erythrocytosis was prescribed, and CPAP therapy for severe sleep apnea was initiated, which made it possible to perform simultaneous stenting of the affected coronary arteries and transcatheter aortic valve implantation.

It takes at least several months from the suspicion of amyloidosis to the diagnosis. This delays the start of specific therapy. Diagnosis of amyloidosis should consist not only in the differential diagnosis and confirmation of the diagnosis, but also in determining the type of amyloidosis. The case report is interesting in that paraclinical diagnostics determined the picture characteristic of ATTR-amyloidosis with involvement to the peripheral nervous system and heart, as well as the picture of AL-amyloidosis with predominant renal involvement. For the final diagnosis, repeated biopsy with subsequent amyloid typing was required.

The purpose of this study is to development a program for enhancing special teachers’ competency to use educational drama in Korean Language class; the design is based on basic processes including analysis, design, development, execution, and evaluation of the ADDIE model. In the analysis phase, factors of competency to use educational drama in Korean Language class were derived through a review of previous studies and literature; accordingly, the educational purpose and goal of the program were established. In addition, in order to reflect the needs of incumbent teachers, in-depth interviews were conducted with six incumbent special education teachers; this was then followed by a questionnaire survey of 109 incumbent special education teachers. By reflecting the needs of special education teachers collected through in the design phase, the educational purpose and goal of a program for enhancing competency to utilize educational drama in Korean Language class was clearly implemented based on the theoretical basis. In the development phase, the contents of education, teaching and learning methods, educational evaluation, and operation methods were decided; from this, a program plan was derived. The program plan was revised and supplemented twice through content validity review by 10 experts; based on this, a program plan for each two types of session number was developed. In the implementation phase, based on the program plan for each session numbers, programs of 15 sessions with 30 hours were administered for five special education teachers currently working for schools. In the evaluation phase, along with the changes that occurred after the implementation of the program plan, the self-evaluation was conducted during the process. This study confirmed the necessity of Korean Language classes using educational drama in the field of special education. Furthermore, based on this, this study presented a program model to comprehensively enhance the teaching competency of special education teachers.

Herbal products found in nature can serve as great systems of study for drug design. The Amanita muscaria mushroom is native to many parts of the Northern Hemisphere and has a very distinctive appearance with its red cap and white spotted warts. The mushroom comprises several pharmacologically active alkaloids, including muscazone, muscarine, ibotenic acid, and muscimol, the latter two compounds being potent GABA agonists. Muscimol has served as a backbone in the design of GABA agonists devoid of effects on the GABA-metabolizing enzyme, GABA transaminase, and GABA uptake systems. In this sense, several analogs of muscimol have been synthesized and studied including THIP, THPO, iso-THIP, iso-THAZ and 4-PIOL which all interact with the GABA receptors much differently. The growing pharmacological and toxicological interest based on many conflicting opinions on the use of the neuroprotective role of muscimol analogs against some neurodegenerative diseases, its potent role in the treatment of cerebral ischemia and other socially significant health conditions provided the basis for this review.
