Red tides are becoming more common in aquatic ecosystems, particularly the coastal habitats which are highly influenced by climatic and anthropogenic activities. We provide the first report of a red tide event in Meda creek, west coast of India. Light and scanning electron microscopy were used to identify the bloom forming organism, while physicochemical, biological and biooptical parameters were determined to characterize the aquatic body of the Meda Creek. The dominant bloom forming organisms were observed as unarmored, spherical, dorsoventrally compressed flagellate with truncated apex, notched and rounded hypocone, displaced premedian cingulum and extending sulcus. The length wise size of the cell varied from 20 to 30.83μM, whereas, the width varied from 14 to 27.5μM. The organisms was identified as Gymnodinium sp. High Performance Liquid Chromatography (HPLC) and spectral profile of the bloom indicatedeleven major peaks corresponding to that of 19-but-fucoxanthin (52.75%), astaxanthin (9.62%), fucoxanthin (8.81%), Mgdv (6.45%), prasinoxanthin (3.35%), chlorophyll C2 (3.22%), neoxanthin (3.12%), antheraxanthin (3.14%), diadinoxanthin (2.63%) and diatoxanthin (1.38%). Chlorophyll a concentration in the bloom sample was 38.8μg/L. Water temperature, salinity, NH3-N, NO2-N, NO3-N, PO4-Pwere higher during the bloom period than the non-blooming ones, while metals including Fe, Zn, Cr, Mn and Co were lower. No death of aquatic biota was observed. We propose that eutrophication along with the warm and saline conditions provided enabling conditions for occurrence the bloom. Also, most of the pigments expressed have antioxidant role and might be purposeful for the survival of the organism in the extreme condition of temperature and salinity recorded. Proper management and monitoring measures might help mitigate further occurrences of this bloom in the light changing climate and increasing anthropogenic impacts.

The crush-leach process was investigated as a method to treat GEN IV simulated ceramic-coated reactor fuel. Simulated ceramic-coated fuel was prepared using fine carbon as a coating and surrogate elements for fuel, the method retained the bulk of the carbon components in elemental form, which is favorable for achieving waste reduction goals. Simulated ceramic-coated fuel was crushed and nitric acid was added to the fines as slurry that led to rapid and effective leaching of the heavy metal. The leaching process of simulated crushed ceramic-coated fuel and extraction behavior of the separated leaching solution was tested at the laboratory scale. Results showed that carbon used in the preparation of stimulated fuel was difficult to be separated by filtered, indicating the need to carefully control particle size and/or use alternative solid-liquid separation methods. Foams or emulsions was not observed during the solvent extraction step, which indicated that measurement of the distribution ratios for actinides elements were slightly larger than predicted by previous models. This increase may be due to small concentrations of organics; however the experimental results are not conclusive. Although the results do not strongly indicate effects by a contaminating organic agent, the organic species may exist in small concentrations. Such an organic species could affect the extraction behavior of the solvent if it accumulates over time.
Photoinduced Crystal Melting with Luminescence Evolution Based on Conformational Isomerisation

Published: February 2023

The phenomenon of crystal melting by light irradiation, known as photoinduced crystal-melt transition (PCMT), can dramatically change material properties with high spatiotemporal resolution. However, the diversity of compounds exhibiting PCMT is severely limited, which hampers further functionalisation of PCMT-active materials and the fundamental understandings of PCMT. Here, we report on heteroaromatic 1,2-diketones as the new class of PCMT-active compounds, whose PCMT is based on conformational isomerisation. In particular, one of the diketones demonstrates luminescence evolution prior to crystal melting. Thus, the diketone crystal exhibits dynamic multistep changes in the luminescence colour and intensity during continuous ultraviolet irradiation. This luminescence evolution can be ascribed to the sequential PCMT processes of crystal loosening and conformational isomerisation before macroscopic melting. Single-crystal X-ray structural analysis, thermal analysis, and theoretical calculations of two PCMT-active and one inactive diketones revealed weaker intermolecular interactions for the PCMT-active crystals. In particular, we observed a characteristic packing motif for the PCMT-active crystals, consisting of an ordered layer of diketone core and a disordered layer of triisopropylsilyl moieties. Our results demonstrate the integration of photofunction with PCMT, provide fundamental insights into the melting process of molecular crystals, and will diversify the molecular design of PCMT-active materials beyond classical photochromic scaffolds such as azobenzenes.
Best Practices for Using Genetic Algorithms in Molecular Discovery
Authors: Greenstein Brianna , Elsey Danielle , Hutchison Geoffrey
Published: February 2023

Genetic algorithms (GAs) are a powerful tool to search large chemical spaces for inverse molecular design. However, GAs have multiple hyperparameters that have not been thoroughly investigated for chemical space searches. In this work, we examine the general effects of a number of hyperparameters, such as population size, elitism rate, selection method, mutation rate, and convergence criteria, on key GA performance metrics. We show that using a self-termination method with a minimum Spearman's rank correlation coefficient of 0.8 between generations maintained for 50 consecutive generations along with a population size of 32, 50% elitism rate, 3- way tournament selection, and a 40% mutation rate provides the best balance of finding the overall champion, maintaining good coverage of elite targets, and improving relative speedup for general use in molecular design GAs.
Photochemical synthesis of acyl fluorides using copper-catalyzed fluorocarbonylation of alkyl iodides
Authors: Tung Pinku , Mankad Neal
Published: February 2023

Acyl fluorides are important reagents in organic synthesis due to their unique balance between reactivity and stability. Here, we report a copper-catalyzed carbonylative coupling strategy to synthesize acyl fluorides under photoirradiation. Various alkyl halides were transformed in high yields into corresponding acyl fluorides by using a commercially available copper catalyst (CuBrSMe2) and a readily available fluoride salt (KF) at room temperature and mild CO pressure (6 atm) under blue light irradiation. A radical fluorocarbonylation mechanism is proposed based on experimental data.
Solvation structure of conjugated organosulfur polymers for lithium-sulfur battery cathodes
Authors: Gayen Diptesh , Schütze Yannik , Groh Sebastien , Dzubiella Joachim
Published: February 2023

Lithium-sulfur (Li/S) batteries constitute a promising, next-generation energy storage technology due to their high theoretical energy density and low cost. To increase sustainability, processability, and battery performance, conducting organic polymers have become a focus of research for the development of better cathode materials. Here, we investigate the solvation structure of the conjugated poly(4-thiophen-3-yl) benzenethiol) (PTBT) polymer as a high-potential macromolecular candidate for cathodes in Li/S batteries. Using molecular dynamics (MD) simulation with newly optimized force-field parameters, we examine the effects of polymer length and various molar fractions of the popular dimethoxyethane (DME) and dioxolane (DOL) solvents on the structure of the PTBT polymer at a temperature of 300 K. We characterize basic polymeric properties as well as the composition-dependent solvent adsorption structure and thermodynamics. Importantly, we find an interesting co-solvency effect, namely that a solvent comprised of about 25% DME and 75% DOL leads to maximum swelling (best solvent quality) behavior, which should be important for optimizing cathode fractality and permeability in applications. Our study thus reveals intriguing polymer-solvent correlations and serves as a first step for further MD studies of realistic polymeric cathode structures and processes, e.g., toward charge transport in vulcanized (S-linked) network topologies.

Published: February 2023

The lack of practices of Curriculum Merdeka cause science teachers to worry about the results, especially related to environmental awareness. As such, this study aimed at exploring the role of biotechnology learning with embedded sustainable development goals (SDGs) to accomplish the academic purposes of the curriculum. In doing so, Pre-service Science Teachers (PSTs) were required to develop projects in biotechnology as well as problem-solving skills to be induced into their teaching competencies. This study used one-group pre-test and post-test design and involved twenty PSTs as participants. The parameters were perception, knowledge, and development of scientific projects. The instruments consisted of questionnaire, paper-pencil test, and rubrics. The data were then analysed in a descriptive manner. The results showed that most students perceived that biotechnology learning provides access to sustainability in human life. Also, there is a significant increase of student knowledge about innovating science with P-value of 0.00<0.05. For scientific projects, students in groups successfully created five titles in relation to SDGs issues, such as food nutrients, agricultural pests, fish-pond management, dengue fever control, and water quality. In terms of learning outcomes and themes, the contents within PSTs projects are relevant to two learning outcomes and four different project themes of Curriculum Merdeka, including lifestyle for sustainability, technology to support Indonesia, entrepreneurship, and local wisdom. Therefore, there is potential to bring PSTs projects to practice Curriculum Merdeka.

Published: February 2023

The main aim of this study is to measure the dynamic connectedness and spillover effects among emerging stock markets in Asia and the developed stock markets of the US and Europe in the ongoing Ukrainian crisis. The paper also aims to provide a comparative analysis of return and volatility spillovers during the global financial crisis in 2008, the COVID-19 pandemic, and the Ukrainian crisis. This paper utilizes the multiple structural beak test of Bai & Perron (2003) and also depicts the risk and return transmissions among these markets using the Diebold & Yilmaz (2012) method. The main outcomes of this study indicate that the stock markets in Asia are less affected by the political crisis in Ukraine as compared to the previous effects during the GFC and COVID-19 periods. The results also show that sensitivity of Asian financial markets to global shocks has been weakened in the wake of the Ukrainian crisis in favour of increased resilience of Asian stock indices to external shocks. These results carry an important implication for international and local investors as well as for policy makers in Asia, where investors have greater potentials for portfolio diversify and risk reduction across Asian markets. Doi: 10.28991/ESJ-2023-07-02-04 Full Text: PDF
“IT WAS (NOT) THE RIGHT CUSTOM”. THE RITUAL OF LEFT HAND RAISING IN THE THANATOLOGICAL DISCOURSE OF THE CIRCASSIANS DIASPORA
Authors:   Erciyes University, Pashtova Madina M.
Published: February 2023

The custom of raising the left hand has been preserved until recently in the thanatological practices of one of the Circassian diaspora communities in Turkey (Uzunyayla – Kayseri). According to the stereotypical narrative descriptions of the ritual, one of the groups arriving at the funeral slowly steps forward, taking three steps from the left foot, and slowly raises the left wrist to the level of the chin, temple, or crown. By raising his hand, the condolent publicly expresses the recognition of the social status of the deceased. According to informants, in the late 1980s, the custom was eradicated under the pressure from the Islamic clergy. Those who opposed its cessation understood this custom as a sacred one ‘brought from the ancestral homeland’ and bequeathed by Zhabagi Kazanoko (the folkloric and historical hero, philosopher, humanist and reformer of the 18th century). The idea of “reviving” the ritual was initiated during the pandemic, when mass gatherings and physical contacts (handshakes and embraces, which are common in ordinary funeral practices) were prohibited. In particular, in relation to the Day of Remembrance of the Victims of the Caucasian War (celebrated by the Circassian community annually on May 21), it was proposed to hold an online campaign for posting photos with a raised left hand. The explicit and hidden strategies of actualizing the ritual of raising the left hand as “our own”, “the primordial” and ‘undeservedly forgotten one’ are analyzed in this work on the material of the texts of classical folklore (heroic legends) and memoranda recorded by the author during fieldwork, as well as posts on the social media. The main aim of the research is to show how the bearers of the tradition reproduce (verbally and visually) the stable and changeable structures of a narrative / a ritual under the influence of certain ideological dominants.

PHENOMENA OF FUNERAL, BORDER, TRANSITION IN THE CONTEXT OF REPRESENTATIONS OF THE OTHERS IN GREEK VASE PAINTING
Authors:   Independent researcher, Tereshchenko Tatiana S.
Published: February 2023

Greek perception of the Others was syncretic: real facts were mixed with fantastic ideas; in their view the Others lived on the outskirts of the oikumene, that is on the border with the other worlds – in the broad sense – real and fantastic, the world of alive and dead – this connected them with the phenomena of borders, transition, burial, etc. Due to this, the Others in Greek art were often represented in mythological subjects and as mythological characters. Also, some subjects where the Others were represented were connected with the phenomena of transition and burial – war, preparations for war, hunt, etc. Also, some details of such images were connected with these phenomena. The semantics of the Greek vase painting was controversial and multilayered therefore interpretation of many of such images is disputable. Besides, the phenomena studied might be examined in a more narrow or more broad sense. Moreover, the connection of many characters represented with the other world, other gods and myths is much more complicated and outgoes far beyond the borders of the thematic connected with the Otherness.

Un consorcio bacteriano (BCA) y un aditivo rico en fosfato (RPA) fueron evaluados como aditivos agrícolas para la reducción de la acumulación y translocación de arsénico (As) en maíz (Zea mays). Se llevó a cabo un experimento con macetas en suelo agrícola contaminado. Después de 10 semanas de crecimiento, se cosecharon las plantas, se midieron los parámetros de crecimiento (altura y peso) y se analizaron las concentraciones de As en las raíces y partes aéreas de las plantas. También se midió el pH, la conductividad, el contenido de carbono orgánico total, PO43-, Pb, Fe y Mn en el suelo y la concentración de Pb en las plantas. BCA y RPA tuvieron un efecto significativo (P < 0.05) en la reducción de la bioacumulación de As (11-16 %) en comparación con los experimentos control, pero no en la translocación de metales de la raíz a las partes aéreas. Los parámetros de crecimiento fueron más altos con BCA que con RPA. Los resultados de este estudio podrían contribuir al desarrollo de prácticas agrícolas para la reducción de la exposición humana al As por el consumo de maíz procedente de suelos contaminados con As.

Coating of coconut coir rope as a material for fishing gear is carried out to inhibit the decomposition process and increase the breaking strength and elongation of the rope. In this study,the coating of coconut coir rope using chitosan as an antimicrobial is expected to inhibit the growth of micro-organisms. This study aims to determine the elongation and breaking strength of chitosancoated coconut coir ropes. The research method used is experimental. Data analysis used the Kolmogorov–Smirnov normality test and RAL (Completely Randomized Design)- to determine the effect of chitosan coating on the elongation and breaking strength of coconut fiber ropes. The results showed that the chitosan coir rope had a dark brown color, while the control coir rope had a light brown color. The direction of the twist is "S", with a "hard" type of twist so that the rope tends to be stiff. The fiber type is staple fiber (short fiber). The elongation of the chitosan coir rope was 10.21 cm, 17.55% higher than the untreated coconut coir rope, which was 8.68 cm. The average breaking strength of chitosan coir rope was 37.41 kgf or 11.87% higher than untreated coconut coir rope, which was 33.44 kgf.

Keywords: elongation, breaking strength, chitosan, chitosan coconut fiber rope.
Restorative Justice as an Alternative for The Settlement of Corruption Crimes That Adverse State Finances in The Perspective of The Purpose of Conviction
Authors: Lasmadi Sahuri , Sudarti Elly
Published: February 2023

This research was motivated by the rampant corruption crimes committed by state officials. The problem is that the restoration of the stateâ€™s financial losses due to the corruption crimes with the current system has not met a profitable solution. This research was doctrinal with a normative legal research method, which was a legal research method based on the statutory and conceptual approaches using analytical descriptive analysis. Settlement of corruption crimes concerning state financial losses is currently carried out through a criminal justice system that priorities a retributive justice approach so that it does not achieve the objective of punishment of un optimal returns to state financial losses. Therefore, a new settlement concept is needed. The concept of restorative justice focuses more on the settlement of criminal cases by emphasizing restoration to its original state, not retaliation. Restorative justice also fulfills the value of justice and legal benefits in order to meet the value of legal certainty. In the future, it is necessary to formulate specific regulations regarding the concept of restorative justice in resolving corruption crimes concerning losses on state finances.

Paraphrase Patterns of Expert Academic Writers: Implications for Writing Development, Writing Pedagogy, and Plagiarism Policies
Authors: Michiels Paul , Kessler Karyn , Rogers Paul
Published: February 2023

This study offers a linguistic analysis of language borrowing in expertly produced paraphrases. Within the context of higher education, paraphrase writing, an essential skill for source-based writing tasks across the curriculum and a key component in the development of disciplinary expertise, represents a challenge for students and teachers because 1) there is no precise and generally accepted definition of acceptable academic paraphrase, 2) discussions of paraphrase are more often framed in terms of plagiarism than effective writing, and 3) little is known about the linguistic (or rhetorical dimensions) of paraphrases in writing published by experts. The present study analyzes five corpora of paraphrase/source passage pairs (n = 233) produced by expert writers. Corpora 1 and 2 contain exemplar paraphrase/source passage pairs drawn from writing guides and handbooks designed for college students. The remaining three corpora of paraphrase/source passage pairings were assembled using award-winning published articles in three disciplines. Using Keck’s (2006) taxonomy for classifying paraphrases, the study found that about 27% of the average paraphrase of the expert writers analyzed here is made up of language found in the source passage. Paraphrase patterns of expert academic writers point toward a potential continuum of acceptable language borrowing practices likely driven by disciplinary differences. Implications for writing development, writing pedagogy, plagiarism policy, and further research are discussed.

A 28-year-old man was taken to our hospital with sudden onset of severe headache. The computed tomography (CT) scan revealed subcortical hemorrhage of the right temporal lobe. The patient has past medical history of hemophilia C (XI factor deficiency). On neurological examination no deficit was observed (Glasgow Coma Scale (GCS) -15). 10 hours after admission, his GCS and CT scan of the brain were unchanged. After consultation with the hematologist, he received fresh frozen plasma, mannitol, tranexamic acid during the treatment. But 36 hours after admission, the neurological status was worsened (GCS -12)․ A decision was made to immediately perform a temporal craniotomy with evacuation of intracerebral hematoma. Surgery and the postoperative period were uneventful․ The patient was discharged without neurological deficit․ This case highlights the importance of adequate preparation of the patient presurgically as much as possible to minimizes the risk of complications (rebleeding) during the operation and in the postoperative period.

This study is conducted with the aim to understand the factors that encourage the revisit intention of visitors to a tourist place. We consider several aspects such as tourist satisfaction, tour guide performance, destination attachment, and digital payments adoption in tourist destinations. This study uses quantitative methods through a survey of 294 tourists which is chosen by incidental sampling, who visited tourist destinations in West Java Province, Indonesia. The data obtained were processed using the Structural Equation Model with the help of AMOS 7 software. This study indicate that tour guide performance, digital payments adoption, and destination attachments positively influence visitor satisfaction. We also proved that tour guide performance, destination attachment, and tourist satisfaction positively influence revisit intention. Tourist satisfaction mediates the relationship between tour guide performance, destination attachment, and revisit intention. This study justifies the factors that determine the high intention to visit tourist destinations in West Java Province, Indonesia. It sheds lights on tourism literature by identifying factors that influence tourist satisfaction, namely tour guide performance, digital payments adoption, and destination attachments.

This study aims to fill the salient gap in the area of museums' atmospheric elements by examining their effect on the Egyptian visitors’ behavioral outcomes and the resulting effect on their intention to revisit the museum. An online questionnaire was distributed to a convenient sample of the Egyptian museums' visitors (346 respondents) to gather and analyze primary data along with analyzing the secondary data (literature). The results confirmed that museum's atmospheric elements have a positive and significant effect on the visitors’ experiences. This resulted in positive behavioral outcomes that consequently affected the Egyptian visitors’ intention to revisit the museum. This study investigates the importance of taking the physical design and atmospheric elements into consideration by the museum curators and managers, especially during the current phase in Egypt where various museum renewals and constructions are being held.
Foreigners in Their Own Home: De Facto Displacement and Negative Emplacement in the Borderlands of Abkhazia
Authors: Venhovens Mikel J.H.
Published: February 2023

This article explores de facto displacement and negative emplacement dynamics in the borderlands of the de facto state of Abkhazia. The uncertain status of de facto states creates a vulnerable, disenfranchised and rearranged post-conflict environment for ethnic minorities that are deemed unwanted remnants of the conflict. I make two arguments: First, de facto displacement is a situation of displacement where the displaced do not physically move away but where the landscape around them together with the sociopolitical situation significantly changes almost overnight. Second, that this displacement comes with negative emplacement in which a person and/or group is negatively set in place in a physical and social sense within the newly created reality of the de facto state.
Evaluation of Artemia sp. (Branchiopoda, Artemiidae) as an alternative prey for laboratory rearing of Tupiocoris cucurbitaceus (Hemiptera: Miridae), a predator of horticultural pests

Tupiocoris cucurbitaceus (Spinola) (Hemiptera: Miridae) is a predator of whiteflies (Hemiptera: Aleyrodidae) present in several American countries. Rearing this bug requires the use of plants as ovipositional substrate and a prey to feed on to complete its development. Artemia sp. (Branchiopoda, Artemiidae) cyst, a crustacean tested for the laboratory rearing of other hemipteran species, could be used as food, being less expensive than the species commonly employed (Sitotroga cerealella [Olivier] [Lepidoptera: Gelechiidae]). The objective of the present study was to determine nymphal developmental time, nymphal mortality, fertility, and sex ratio of T. cucurbitaceus fed on Artemia sp. cysts. Three diets were used during the rearing of three generations: S. cerealella eggs, Artemia sp. cysts and a mix of both species. The nymphal developmental time (11 to 13 days), nymphal mortality (40 to 66 %), and adult fertility (74 to 101 nymphs / female) were similar for all diets. In all cases, the adults showed a high female proportion (0.67-0.97). In conclusion, Artemia sp. cysts are suitable for T. cucurbitaceus laboratory rearing at least for three generations.
Developing machine learning models for air temperature estimation using MODIS data

Air temperature is a key variable in a wide range of environmental applications, including land–atmosphere interaction, climate change research and hydrology and crop growth models, among others. The objective of this study was to estimate daily maximum (Tmax) and minimum (Tmin) temperatures, based on MODIS AQUA/TERRA land surface temperature (LST), NDVI, extraterrestrial solar radiation and precipitation data. Artificial neural networks (ANN) and random forests (RF) models were developed to predict these temperatures covering weather stations in Córdoba (Argentina) for 2018-2020. The results show that RF and ANN machine learning algorithms are capable of modeling non-linear relationships between registered temperatures and LST MODIS data, in a very robust way. The validation of the models confirms that Tmax and Tmin can be accurately estimated using, jointly or separately, AQUA and TERRA LST. The best models present determination coefficients equal to 0.81/0.91 and root mean square error of 2.7/2.1 ºC for Tmax/Tmin, when using AQUA LST day/night satellite overpass time data, respectively. The robustness and confidence of the models developed, and the ease and free accessibility of input data at a global scale, suggest that these methodologies have the potential to be applied to other regions.

Entre las principales limitaciones para la producción de amaranto, se señalan diversas especies de insectos fitófagos. Se propuso como objetivo aportar al conocimiento de las especies de herbívoros y enemigos naturales asociados a este cultivo, determinando densidad, momentos de aparición y su relación con las etapas fenológicas. En parcelas experimentales de Amaranthus hypochondriacus ubicadas en el Campo Escuela de la Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, se realizaron muestreos semanales, desde emergencia hasta madurez fisiológica del cultivo, durante las campañas agrícolas 2016, 2017 y 2019 para obtener ejemplares de fitófagos y predadores. La comunidad de insectos estuvo conformada por 5 órdenes, 21 familias y 40 especies. Coleoptera mostró la mayor abundancia de ejemplares. Se destacó la importancia de la oruga defoliadora Achyra similalis y de dos especies de barrenadores, Conotrachelus histrio y Aerenea cuadriplagiata, por su presencia y abundancia en la etapa reproductiva del cultivo. A partir de larvas de Lepidoptera, se obtuvieron seis especies de parasitoides (Hymenoptera y Diptera). Principalmente asociados a orugas pequeñas y colonias de pulgones, se registraron además seis especies de predadores (Coleoptera, Hemiptera y Diptera).
The Existence of Pure and Sacred Silver Craft Creation in Gianyar Bali

Published: February 2023

This study aims to discover in depth the existence of the creation of pure and sacred silver crafts today and the public's attention to these works. The results of this study will also be very useful for craftsmen, entrepreneurs, academics, and the government as information material about the growth and development of the creation of silverworks in an uncertain tourism situation. The decline in Bali tourism has impacted the decline in silver handicraft production in Gianyar, especially in products for tourism needs. Several areas that used to be centers of silver crafts, such as Celuk Village, Singapadu Village, and Taro Village, are now no longer productive because they rarely receive orders. In a quiet situation, some creative and highly skilled craftsmen began to divert their production by creating several pure art and sacred art as collectibles and Sesuhunan (sacred crafts) such as Barong, Rangda, and Masks which are purified and sacred by the Balinese people. The orientation of creating silverworks eventually leads to works of high quality and aesthetic value. A very interesting phenomenon to study holistically is the following: how is the existence of the creation of pure and sacred silverworks in Gianyar today? The method used in this study is a descriptive qualitative method with data collection techniques of observation, interviews, and documentation. This paper is also very appropriate to be carried out to examine in depth the development of silverworks of pure art and sacred art. There is a huge struggle between cultural and economic capital in the quest for power and the preservation of silverwork as noble works of art. This research is expected to contribute to science, especially related to arts and crafts in general.
