Authors: Gao Yibo , Luo Jianlin , Li Zhiqing , Teng Fei , Zhang Jigang , Gao Song , Ma Minglei , Zhou Xiaoyang , Tao Xuejun
Published: July 2023

In this review, the research reports on the dispersion processes of carbon nanotubes (CNTs) in aqueous cementitious materials are intensively introduced and summarized. The main processes for the CNTs dispersion in aqueous systems include high shear emulsification, ultrasonic treatment, covalent modification, and non-covalent modification. The influences of various factors on the dispersity of CNTs are evaluated, and the pros and cons of dispersion processes of CNTs are analyzed, along with the dispersion mechanism of CNTs in aqueous materials. Several novel techniques are also introduced, including arc thermal excitation and electromagnetic field-induced method, etc. In addition, the challenges when CNTs dispersion are further involved in cementitious alkali pore solution and the improvement means are also described in detail. And, the direct dispersion process (in situ growth process) of CNTs in cementitious materials has also been discussed in depth.

Authors: Falk Armin , Kosse Fabian , S. Stötzer Lasse
Published: July 2023

Dieser Beitrag, der die Thünen-Vorlesung von Armin Falk auf der Jahrestagung des Vereins für Socialpolitik widerspiegelt, ist der sozialen Ungleichheit und Chancengerechtigkeit in Deutschland gewidmet. Die empirischen Erkenntnisse der Forschung von Armin Falk, Fabian Kosse und Lasse S. Stötzer belegen zum einen eine erhebliche Gerechtigkeitslücke, da Kinder aus sozial schwächeren Verhältnissen auf multiple Weise in ihren Startchancen benachteiligt sind. Zum anderen zeigt sich aber, dass diese Lücken keinesfalls hingenommen werden müssen: Durch geeignete Interventionen, insbesondere Mentoringprogramme, können sie stark reduziert werden.

Authors: Zheng Wei , Amin Muhammad Nasir , Khan Kaffayatullah , Sufian Muhammad , Deifalla Ahmed Farouk
Published: July 2023

In the construction industry, the incorporation of steel fibers in ultra-high-performance concrete (UHPC) is vital for improving its mechanical characteristics. In order to identify the essential factors of UHPC, the literature on the effect of steel fibers on UHPC is reviewed using scientometric methods in this work. The review contains complex processes like knowledge mapping, co-occurrence, and co-citation. In order to analyze the bibliographic data on the impact of steel fibers on UHPC, this study makes use of contemporary methodologies for data processing, mining, analysis, presentation, and visualization. The aim is to provide direction for further research in this area by summarizing the literature. In order to achieve this goal, data from the Scopus database, including publication sources, top authors, keywords, significant publications, and nations contributing the most to the subject, are retrieved and examined. According to the scientometric analysis, the most frequently used keyword is “steel fibers,” “Construction and Building Materials” is the most popular publication source in terms of citations and articles, and China is the top-ranking nation in the industry. Academic scholars can gain from this study’s graphical and quantitative portrayal of the contributing researchers and nations by making it easier to share concepts and form collaborative initiatives. This study also shows that steel fibers can improve the mechanical properties of UHPC but their widespread manufacturing and use are dependent on factors including the fiber content and geometry.
Matrix autoregressive models: generalization and Bayesian estimation
Authors: Celani Alessandro , Pagnottoni Paolo
Published: July 2023

The issue of modelling observations generated in matrix form over time is key in economics, finance and many domains of application. While it is common to model vectors of observations through standard vector time series analysis, original matrix-valued data often reflect different types of structures of time series observations which can be further exploited to model interdependencies. In this paper, we propose a novel matrix autoregressive model in a bilinear form which, while leading to a substantial dimensionality reduction and enhanced interpretability: (a) allows responses and potential covariates of interest to have different dimensions; (b) provides a suitable estimation procedure for matrix autoregression with lag structure; (c) facilitates the introduction of Bayesian estimators. We propose maximum likelihood and Bayesian estimation with Independent-Normal prior formulation, and study the theoretical properties of the estimators through simulated and real examples.
A Scientist’s and Tourist’s Touch – The Haptic in Travelogues about the Island of
Java (M. Siedlecki and E.R. Scidmore)
Authors:   Shanghai International Studies
            University, China, Ewertowski Tomasz
Published: July 2023

The article explores the haptic aesthetic of selected Polish and Anglophone
travelogues about the island of Java: Jawa – przyroda i sztuka (1913) by a Polish
biologist named Michał Siedlecki, and Java, the Garden of the East (1897) by the
American writer Eliza Ruhamah Scidmore. A comparison of texts coming from different
literary traditions should yield a deeper insight into the various aspects of
conceptualising the haptic in travel writing. Javaʼs tropical environment provided
travellers with new sensory experiences, consequently scrutinising how writers
represented what they touched and felt, along with how descriptions of haptic sensations
were associated with the ideological and aesthetic dimension of travel writing, can shed
new light on how travel writing works and how multi-layered it is.

Authors: Sevim Hasret Ozan
Published: July 2023

Goal – to analyse the different and comprehensive aspects of the European Union’s approach to distributed ledger technologies and crypto-assets with a teleological interpretation then finally foresee what kind of policy is going to be adopted by the European Union regarding distributed ledgers. Research metodology – the article includes an analysis of the current and upcoming legal acts and regulations of the European Union regarding distributed ledger technologies and crypto-assets. A multi-disciplinary approach is adapted to understand the financial and technological reasons of European Union’s policy. Score/results – many regulations and directives have been legislated by the European Union and more regulations are in the final phase of the legislation process. Since the global hubs of the distributed ledgers (especially the United States and the Republic of China) have put negative pressures on the crypto-assets and their underlying technologies, the European Union is a candidate to be a new global hub with its ongoing technology-agnostic approach. Originality/value – the effort for the harmonization between a range of different regulatory areas such as anti-money laundering regulations, public financial regulations and the legal infrastructure for pilot regimes regarding distributed ledger technologies and crypto-assets will bring a new impulse to the promoting innovation in a politically and financially safe zone of the European Union.
Risk of Global Economic Crisis in 2022 and the Mechanism of Transmission of Economic Shocks between the Main Areas of the Global Economy
Authors:   Cracow University of Economics, Pera Jacek
Published: July 2023

Goal – the aim of the study is to analyze the main economic areas of the global economy in terms of the possibility of transferring the crisis in relation to the current global economic situation. Research methodology – the analysis conducted was based on literature research; the empirical analysis used causation in the Granger sense and Pearson’s linear correlation coefficient. Score/results – The existence of the so–called “locomotive effect” was observed for a group of countries: USA–CSSA, CSSA–USA, EA–LA, EA–CSSA, LA–EA, CSSA–EA, MECA–LA, MECA–CSSA, LA–MECA, CSSA–MECA, EDA–CSSA, CSSA–EDA, LA–CSSA, CSSA–LA, meaning a positive domestic shock transmitted to the economic partner, among the countries studied, the analysis is carried out based on annual data of GDP values as a measure of economic activity. CSSA remains the safest economic area and also the most neutral in view of the current global economic and political situation. In the WPE, there is a maximum [full] correlation of 1 for: EDA–USA, MECA–EA, EDA–EA, MECA–EDA and EDA–MECA. These are currently the most dangerous and crisis–prone areas, with potential for transferring crises between them. It is facilitated by territorial cohesion and the geopolitical situation between countries in these economic regions. Relatively high correlations can also be observed in these areas between the analyzed factors: IMP, IMG, IDCF and PC. The risk of transferring a crisis resulting from war between the areas mentioned is the highest here. Other correlations in terms of: USA–EA, USA–LA, EA–USA, LA–USA, LA–EDA, EDA–LA remain at weak or average levels. This is influenced by geographic distance and the lack of strong economic and political ties. Originality/value – the originality of the study results from the topic undertaken. Identification of potential crisis areas and channels of crisis transmission in the current global geopolitical situation constitutes an added value.

Authors: Pol Sukhsiddhi D. , Prakash Anand
Published: July 2023

Background: Technology has been an integral part of our lives, and it has both positive and negative effects on adolescents. The engagement in structured extracurricular activities can be utilized as a prevention method for technology or internet addiction. This can channel their time and energy in the right direction and empower valuable results for youth. The present study was conducted to compare adolescents engaged in structured and non-structured extracurricular activities in terms of spending time on computers using the internet for education and entertainment.
Methodology: In a cross-sectional research design, the Strength and Difficulty Questionnaire was administered to a total of 124 adolescents (75 males and 49 females) to exclude adolescents with behavioral disturbances. In addition, a semi-structured interview was also used for understanding and analyzing the impacts of structured and unstructured extracurricular activities (in terms of frequency and duration).
Results and Conclusion: Results indicated that academic grades were highest in adolescents involved in structured extra-curricular activities. Internet use and mobile use for social purposes were found to be higher among adolescents involved in structured extracurricular activities. Thus, active participation in structured extracurricular activities leads to the holistic development of adolescents, better academic performance, and decreased involvement in technology.

Sociedade civil, propriedade privada e o Estado de estamentos: sobre as críticas marxistas à Filosofia do Direito
Authors: Mirian Monteiro Kussumi
Published: July 2023

O presente artigo busca determinar uma análise comparativa centrada na concepção de sociedade civil na Filosofia do Direito de Hegel e as subsequentes críticas marxistas sobre esse tema. A sociedade civil, entendida como o locus da universalidade formal, apresenta três elementos constitutivos fundamentais: a realização do direito abstrato, principalmente através de relações contratuais; a finalidade de satisfação do chamado sistema de carências; uma organização interna ordenada pela noção de estamento – este último, contudo, apresentando um aspecto não apenas social, mas também político. Desse modo, segundo a proposta hegeliana, a sociedade civil ganha uma dimensão política a partir de um nível representativo na administração do direito (participação no poder legislativo). Diante de tais formulações, buscamos em seguida explorar as críticas marxistas na Crítica da Filosofia do Direito de Hegel não apenas no que se refere à função política da sociedade civil (efetivada a partir do modelo estamental), como ainda abordamos sua crítica geral sobre o próprio estatuto da propriedade privada. A partir dessa confrontação teórica, temos como objetivo demonstrar o afastamento desses dois autores tanto no que se refere à constituição social, quanto à organização do poder político.

Authors: Maulana Muklas , Wardhana I Gede Adhitya Wisnu , Switrayni Ni Wayan , @ Ismail Ghazali Semil
Published: July 2023

AbstractThe notion of the prime graph of a ring R was first introduced by Bhavanari, Kuncham, and Dasari in 2010. The prime graph of a ring R, denoted by PG(R) is a graph whose vertices are all elements of the ring, where two distinct vertices x and y are adjacent if and only if xRy = 0 or yRx = 0. In this paper, we study the forms and properties of the prime graph of integer modulo group, and some examples of the number of its spanning trees. In this paper, it is found that for all n, the maximum degree of vertices of PG(Z_n) is n-1 and the minimum degree of its vertices is 1. Then, we show that for all n, PG(Z_n) is neither a Hamiltonian graph nor an Eulerian graph. We also found some examples of the number of its spanning trees.Keywords: prime graph; spanning trees; Hamiltonian graph. AbstrakKonsep mengenai graf prima dari suatu gelanggang R pertama kali diperkenalkan oleh Bhavanari, Kuncham, dan Dasari pada tahun 2010.

Authors: Concha Toro Marcela del Carmen , Lagos San Martín Nelly Gromiria , Anabalón Anabalón Yasna Belén , López López Carmen Verónica , Becerra Aguayo Patricia Alejandra
Published: July 2023

La pandemia por COVID-19 y el contexto de emergencia socio-sanitaria trajo consigo, entre otras cosas, la oportunidad de visibilizar los cambios requeridos por el sistema formativo y profesional que demanda al colectivo de trabajo social: reinventarse para llevar a cabo nuevas formas de ayuda e intervención social en crisis. Lo anterior implica desplegar todo su potencial para ofrecer recursos de apoyo emocional en situaciones de distanciamiento físico-social bajo modalidad de teletrabajo, en estado de confinamiento o de regreso a la nueva normalidad. Todos estos hechos han ido generando desgaste y agotamiento emocional, tanto en este grupo profesional como en la población estudiantil en formación. El objetivo de este trabajo es relevar la importancia que tiene la educación emocional y la formación de competencias emocionales que fortalezcan el desempeño profesional de futuras personas trabajadoras sociales, no solo en un contexto excepcional sino en cualquier situación cotidiana que requiera de su atención o intervención. El principal motivo es, sobre todo, porque las competencias emocionales tienen directa relación con las habilidades sociales y cognitivas, con el logro de los aprendizajes y con los resultados laborales. Como principal resultado se evidencia la necesidad de implementar programas formativos que promuevan el desarrollo de competencias emocionales a partir de un diagnóstico claro que permita reorientar el proceso de enseñanza y aprendizaje. De este modo se busca aportar a la formación integral de las futuras personas profesionales del trabajo social. Se concluye que las competencias emocionales hacen referencia a un desarrollo humano integral, que apunta a un proceso educativo en la sociedad actual y a un aprendizaje a lo largo de toda la vida que integra el aprender a conocer, aprender a hacer, aprender a ser y aprender a convivir. Finalmente, se recomienda que la incorporación del aprendizaje socioemocional sea gradual, continuo y sistemático; contemplando una estrategia de capacitación permanente dirigida al equipo docente que forma al estudiantado de trabajo social, integrando un enfoque teórico desde la sociología de las emociones que considere la diversidad sociocultural de los entornos y contextos en los que estos se desenvuelven.

A torn generation: Dichotomies and dissonances on sustainability and technological change in in-depth interviews with university students
Authors: Köves Alexandra , Tóth Tamás , Vicsek Lilla
Published: July 2023

In a research study among university students regarding technological change, equality and environmental sustainability, deep-seated dichotomies were found in the students' mental images of the future. This study aims to present these dichotomies as well as propose explanations for them, adding to our understanding of what kind of behavioural barriers inhibit sustainability transformations. The results show that the interviewees truly struggle to decide if the world really is on fire regarding environmental change, if technology is capable of solving the situation, if inequality is truly a problem, and how they can relate to all this. The dichotomies that we found suggest that on the one hand, they find no comfort in the dominant techno-optimistic, eco-modernisation narratives and, on the other hand, they are not aware of any alternatives. The results underline the existence of psychological phenomena such as optimism bias or psychological distancing. In our paper, we also address whether dichotomous thinking poses a problem or whether we may have to accept that dichotomies can become the norm when contemplating the world in its increasing complexity.
Longitudinal changes of grip strength and forearm muscle thickness in young children
Authors: Abe Takashi , Ozaki Hayao , Abe Akemi , Machida Shuichi , Naito Hisashi , Loenneke Jeremy P.
Published: July 2023

Background

Grip strength is a marker of future health conditions and is mainly generated by the extrinsic flexor muscles of the fingers. Therefore, whether or not there is a relationship between grip strength and forearm muscle size is vital in considering strategies for grip strength development during growth. Thus, this study aimed to examine the association between changes in grip strength and forearm muscle thickness in young children.

Methods

Two hundred eighteen young children (104 boys and 114 girls) performed maximum voluntary grip strength and ultrasound-measured muscle thickness measurements in the right hand. Two muscle thicknesses were measured as the perpendicular distance between the adipose tissue-muscle interface and muscle-bone interface of the radius (MT-radius) and ulna (MT-ulna). All participants completed the first measurement and underwent a second measurement one year after the first one.

Results

There were significant (P < 0.001) within-subject correlations between MT-ulna and grip strength [r = 0.50 (0.40, 0.60)] and MT-radius and grip strength [r = 0.59 (0.49, 0.67)]. There was no significant between-subject correlation between MT-ulna and grip strength [r = 0.07 (−0.05, 0.20)], but there was a statistically significant (P < 0.001) between-subject relationship between MT-radius and grip strength [r = 0.27 (0.14, 0.39)].

Conclusion

Although we cannot infer causation from the present study, our findings suggest that as muscle size increases within a child, so does muscle strength. Our between-subject analysis, however, suggests that those who observed the greatest change in muscle size did not necessarily get the strongest.
Multimodal biometric recognition using fused handcrafted features
Authors: Mehraj Haider , Mir Ajaz Hussain , Ana Farkhanda
Published: July 2023

Multimodal biometric systems have been widely implemented in a variety of real-world scenarios due to their ability to overcome limitations associated with unimodal biometric systems. This paper is focused on the combination of the face, ear and gait in a unified multimodal biometric identification system using handcrafted features. These approaches provide robust and discriminative features to solve the biometric problem. In this research, speed up robust features and histogram of oriented gradients approaches have been used to extract features from face, ear and gait. The extracted features are optimized using genetic algorithm and classified using Levenberg-Marquardt backpropagation neural network. The system performance is evaluated on constrained and unconstrained dataset conditions.

Authors: Sadiq Ahmed , Albusoda Bushra , Sheer Ali Tawfek
Published: July 2023

Due to the increase in earthquake activity in Iraq and Middle East during the last two decades, the study and understanding of probable destructive action and the best method to mitigate this effect became more important. So, many improvements and mitigation methods can be used. In this study, the use of permeation grout technique was adopted to prevent the existing soil condition in urban area by using cement kiln dust and bentonite clay. The tests were executed by using 1 g shaking table apparatus to simulate a sinusoidal motion (vibration) at specified different frequencies. The liquefaction phenomena were observed for loose saturated sand at 60 s, 25 s, and 10 s for 0.5 Hz, 0.75 Hz, and 1 Hz, respectively. After mitigation process, the soil liquefaction did not occur until 100 s, 60 s, and 30 s, for the same mentioned frequencies. Besides, the use of cement kiln dust decreases the liquefaction potential and increase the factor of safety.
Sejarah Maritim di Nusantara (Abad VII-XVI): Interkoneksi Kerajaan Sriwijaya, Majapahit, dan Demak
Authors: Mahamid Mochammad Nginwanun Likullil
Published: July 2023

Archipelago, the main theme of this article, is a term for a region known as Southeast Asia today, especially the countries with similar historical events about ancient rulers, such as Indonesia, Malaysia, Singapore, Thailand, Vietnam, Cambodia, and others. Thus, the writing of this article was directed at reviewing material related to the existence of rulers, especially those engaged in the maritime field in the archipelago, with a focus on discussion on three subjects, including Sriwijaya, Majapahit and Demak, and was selected on the basis of similarities in historical events. The method used was descriptive analysis through books and other written materials, such as journal articles and seminar proceedings. Then, a written description of the reading and an unwritten description of the material in the form of photos/pictures were added. Lastly, the analysis was carried out using the concept of “Total History” proposed by Fernand Braudel. In this concept, there were three historical facts in one period, namely events, conjuncture, and structure. The findings of this article explained the development of the three maritime rulers of the archipelago, including the Srivijaya Kingdom (VII-XIII centuries), Majapahit Kingdom (XIII-XV centuries), and Demak Kingdom (XV-XVI centuries), which referred to the concept as an internal event empire since its inception, heyday, and decline. In addition, the interconnection of the three kingdoms was the existence of the side of the descendants of the previous kings and the enthusiasm for building the civilization of the archipelago, which was passed on to the rulers afterward through strengthening in the maritime sector.

This article aims to explain how the conflicts that arose after the 1959 presidential decree. The events of the presidential decree had an important contribution to establishing the basis of the Indonesian state. The formulation of Pancasila as the basis of the state is colored by debates between national figures who have Islamic nationalist and secular nationalist thoughts. Thus giving rise to other prolonged conflicts. In uncovering how the conflict occurred at that time, researchers used historical research methods consisting of heuristics, verification and interpretation. Based on the research that has been done, it can be concluded that the journey in determining the ideology of the state ended with the enactment of the 1959 Presidential Decree by Sukarno. Since then it has been agreed that Pancasila is the legal foundation of the state and the concept of divinity that has been agreed upon is religion in accordance with their respective beliefs.

Antheroporum harmandii Gagnep. is a native plant species of Vietnam, belonging to a small genus of the Fabaceae family. In this study, the bioactivities of different extracts from twigs and seeds of A. harmandii plants collected from Dakrong, Quang Tri province were evaluated. Antimicrobial and antioxidant activities of plant extracts had been done using an agar well diffusion method and DPPH assay. The results showed that methanol, dichloromethane and ethyl acetate extracts from twigs and methanol extract from seeds exerted activities to significantly inhibit two out of nine tested microorganisms. Particularly, the dichloromethane extract from the twigs sample exhibited the highest activity to Micrococcus luteus and Staphylococcus aureus strains with inhibition zones of 4.7 ± 0.3 mm and 2.3 ± 0.2 mm, respectively, at concentrations of 50 mg/mL. The lowest MIC values (500 µg/mL) and 50% inhibition concentration values (IC50) against M. luteus and S. aureus were recorded for the methanol and dichloromethane extracts of twigs. Among tested extracts, the ethyl acetate extract of twigs was the strongest antioxidant, showing radical scavenging potential with IC50 of 117.24 μg/mL. Therefore, A. harmandii species can be suggested as a new source for the isolation of valuable natural compounds.

Poisonous plants are known for toxicity to humans and animals. They comprise a large group of plants in the world. This study aims to collect and systematically document the traditional knowledge of poisonous plants by interviewing Van Kieu and Pa Ko ethnic communities in Quang Tri province. A total of 56 poisonous plant species (27 herbs, 15 shrubs and 14 woody plants) of flowering plants belonging to 26 families and 50 genera were found in the study site. Based on the Recorded Poisonous Plant Proportion (RPPP) values, 25 commonly recorded poisonous plants were selected for analyzing Fidelity Level (FL) and Informants Consensus Factor (ICF). The ICF value of eye irritation, neurologic category, skin irritation, gastrointestinal category and respiratory/cardiovascular category was 0.97, 0.97, 0.96, 0.93 and 0.92, respectively. The most notable species (FL: 100%) in the gastrointestinal category were Ricinus communis L. and Millettia erythrocalyx Gagnep. In the respiratory/cardiovascular category, the most important species (FL: 100%) were Gelsemium elegans (Gardner & Champ.) Benth. and Strychnos vanprukii Craib. The presented results will provide fundamental information for further phytochemical and biological investigation to ascertain the toxic compounds of poisonous plants that may be used for the treatment of appropriate diseases.

The spawning season of the milkfish Chanos chanos (Forsskål, 1775) of the family Chanidae in the Central Coast of Vietnam was determined. A total of 220 specimens (3.20 to 4.50 g body weight, BW) was collected from seven provinces (Nghe An, Ha Tinh, Quang Binh, Quang Tri, Binh Dinh, Khanh Hoa, Ninh Thuan) from January to December 2021. Results showed that the Gonado Somatic Index (GSI) ranged from 2.03 to 16.02 in females and 1.15 to 9.87 in males and had two peaks, one in April–May (13.47–16.02 for females and 8.03–9.87 for males) and another in August-September (11.45–12.32 for females and 6.75–7.98 for males). Conditional factors in females and males ranged from 3.68×10-2 to 4.11×10-2 and 3.02×10-2 to 3.43×10-2, respectively with the highest values found in May (4.11×10-2 for females and 3.46×10-2 for males) and September (3.92×10-2 for females and 3.34×10-2 for males). The Fulton’s and Clark’s indexes were highest in November, 1.82% and 1.67%, respectively and these were then decreased in the following months; the lowest values were recorded between August to September and April to June (0.66–0.74% Fulton and 0.49–0.72 Clark). The gonadal development stages III and IV in females and males were observed from April to June and August to September of the year. Our findings suggest that the main spawning seasons of milkfish take place from April to June and August to September.

Vertical distribution of free–living nematodes from the tropical region are still poorly documented, especially in Vietnam. Field sampling was conducted at the Ba Lai river, a tributary of the Mekong river, to insight into the regularity of the vertical pattern of nematode assemblages. Furthermore, some sediment environmental characteristics such as greenhouse gases were also detected in order to understand how to influence nematode distribution. The study found that nematode composition differed significantly between the upper and deeper layers of sediment but not among the deeper layers. Nematode density showed spatial variability across layers, with higher values in the upper layer. Nematode diversity decreased with increasing depth. Non–selective deposit feeders (1B) were dominated in the surface layers, while the predator–omnivores feeders (2B) was numerous in the deeper layers. In the dry season, both methane and hydrogen sulfur were found negatively affecting nematode diversity in sediment profile, particularly, methane effects negatively also to species richness, densities, and evenness. However, only methane has a significant correlation to the diversity, species richness, densities, and evenness of the nematode communities.

The Sundanese indigenous people are famous for their cultural wisdom, namely pamali. Pamali as a typical Sundanese cultural product has a conditional meaning for children's development that needs to be continuously explored. This study aims to analyze the existence and moral development contained in the pamali of the Sundanese indigenous people in early childhood. This type of research is a systematic review of 20 journals with related criteria using qualitative methods. through the syntax, in literature, there are five traditional villages and two Sundanese villages that still apply pamali as part of the order of life and rules that have been passed down from generation to generation. Each of these pamali contains moral values ​​such as discipline, humility, care for the environment, and politeness which are reflected in the sentence of pamali. In line with Kohlberg's moral development, early childhood is included in the level 1 category, namely pre-conventional morality. The implications for children can be seen from how they can know when the taboos are through an understanding of taboos so it is hoped that this will foster an attitude of obedience to the rules that surround them to strengthen their knowledge of the cultural values ​​of the area.
