Authors: Adinda Sari
Published: April 2024

Pancasila is the unity and unity of the Indonesian nation with the function of being the basis for carrying out government administration and regulating the state structure as a whole. Pancasila is a national symbol that functions as the basis for carrying out government administration and regulating people's daily lives. The Pancasila ideology helps shape the character of a nation that is honest, disciplined, thinks critically, is responsible, is fair, loves the country, is tolerant, embraces each other and has high social awareness. Constitutional Court decisions that reflect constitutional values ensure a reexamination of the 1945 constitution and often lead to conflicting situations such as disagreements over election results that must be resolved by all parties involved. The Constitution has the responsibility to make the first and final decisions regarding changes to laws relating to the 1945 Constitution. The aim of this research is to determine the role of the Pancasila Ideology in the Development of the Constitution and Legal System in Indonesia. This research uses the literature review method, which is research carried out by collecting library data, or research through various sources of information. The results and discussion in this research Pancasila is an ideology or guideline for Indonesian society and the laws that apply in Indonesia must be based on the 1945 Constitution. The Constitution is the foundation of the government and its implementation requires a thorough understanding of the social background and long-term goals of a country. Therefore, the philosophical basis of the constitution must be clear and consistent with the wishes of the government, which basically reflects the wishes of the people. It can be concluded that Pancasila contains values that can be implemented by the Indonesian people. In Pancasila there are the values of norms, ethics and moral behavior. Meanwhile, the 1945 Constitution contains a legal basis in written form. The laws that apply in Indonesia must be in accordance with the 1945 Constitution. The law has a high position, therefore every Indonesian citizen must comply with all applicable laws and will receive sanctions if Indonesian citizens commit deviations.

School Literacy Program Against Merdeka Thinking to Strengthen The Humanistic Learning Process at The Elementary School Level
Authors: Muhammadin Ayatullah , Pamungkas Sri
Published: April 2024

This research aims to 1) Eliminate the uniform clothing system for students, 2) Implement a humanist learning system. The method used is literature review with a qualitative descriptive approach. Data collection techniques use interviews, observation and analysis of analyzed notes. The data taken are documents related to research. The research results show that learning is prioritized using a humanistic approach, but in reality there are still many learning processes that do not implement humanistic learning as a whole. For example, uniformity in clothing for students will ultimately kill students' potential, talents, interests, creativity and work results. The recommendation of this research is that a bottom-up curriculum model is worthy of being developed, so that educational components can strive for the overall curriculum components. However, an educator is a planner, implementer and perfectionist in a learning process. Because educators are the ones who best understand the conditions in the field from Sabang to Merauke, therefore educators are the most competent in compiling a curriculum in the classroom or at school. So the researchers recommend that the school literacy program "independent thinking about local wisdom" be implemented at the elementary school education unit level.

Published: April 2024

In recent years, high-electron-mobility GaN HEMTs have demonstrated significant advancements in applications such as power converters and RF amplifiers. Nevertheless, their thermal reliability poses a notable challenge, placing constraints on their power-handling capacities. This study employs micro-Raman spectroscopy to evaluate the localized self-heating-induced channel temperature. The channel temperature, determined using the single phonon modes of GaN HEMT (E2(H) & A1(LO)), exhibits discrepancies and does not align with device temperature values calculated using the SiC phonon peak near the GaN channel. However, by employing both phonon modes of GaN to decouple the combined effects of joule heating and the thermoelastic effect, accurate channel temperature values are obtained, matching well with those obtained from the SiC phonon peak. The agreement between calculated temperatures from phonon modes and those obtained by heating the device from the back side enhances the credibility of the proposed method.

The average annual mass concentration of PM10 was determined to be 64±6 µg m-3. Carbonaceous aerosols (CAs), comprising OC, EC, WSOC, and SOC, exhibited annual averages of 9.3±0.8 µg m-3, 4.9±0.5 µg m-3, 1.5±0.2 µg m-3, 2.7±0.2 µg m-3, and 2.97±0.45 µg m-3, respectively. The elemental composition featured major contributors such as Ca, Al, Fe, S, and K, alongside trace levels of various elements (Mg, Pd, B, Mo, Zn, Ag, Nb, Ga, Cl, Ti, Zr, Na, and Cr). Positive Matrix Factorization (PMF) identified six primary contributors to PM10, each with varying percentage contributions: crustal/soil/road dust, soil re-suspension, combustion, vehicular emissions, industrial emissions, and biomass burning. The health risk assessment revealed elevated Hazard Quotient (HQ) values for Cr and Mn in children, indicating a non-carcinogenic health risk. Adults exposed to high Cr levels may face potential carcinogenic risks, while elements like Al, Pb, Cu, Zn, and Ni pose no health hazards, aligning with USEPA guidelines.

Tutela Jurisdicional Coletiva nas Ações de Saúde sob a Ótica do Tribunal de Justiça do Estado de Rondônia
Authors: Esteves Cury Coutinho Isabela , Cavalcante Primão Beatriz
Published: April 2024

O artigo discute o aumento da judicialização da saúde no Tribunal de Justiça do Estado de Rondônia, com foco nas ações individuais em detrimento das coletivas. A pesquisa explora a hipótese de que a tutela jurisdicional coletiva pode ajudar a diminuir a demanda judicial relacionada ao direito à saúde no estado. A metodologia usada foi a abordagem qualitativa com coleta de dados por meio de documentos bibliográficos e relatórios públicos, além de dados do próprio tribunal. O resultado indica que o aumento da judicialização da saúde ocorre devido à falta de ação estatal em efetivar o acesso à saúde e que a tutela jurisdicional coletiva é uma das possibilidades para reduzir o fenômeno, mas também é necessário priorizar as tratativas extrajudiciais.

Objetivou-se analisar por meio de estudo retrospectivo a relação entre o número de oócitos, número de embriões, taxa de embriões de sessões de aspiração folicular (OPU) e produção in vitro de embriões (PIVE) de vacas doadoras das raças Gir e Nelore. Analisaram-se dados de 4.238 sessões de OPU/PIVE realizadas em doadoras Gir (n = 1.115) e Nelore (n = 3.123), entre os anos de 2008 e 2010. As variáveis analisadas foram número de oócitos viáveis, número e taxa de embriões e percentual de sessões OPU/PIVE que não produziram embriões na PIVE. Tais variáveis foram divididas em quartis, de acordo com o número de oócitos. Utilizou-se o teste ANOVA para a comparação de médias das variáveis analisadas entre raças e quartis, com teste de homogeneidade de variância de Levene, seguido pelo teste de Bonferroni. O teste qui-quadrado foi utilizado para comparar o percentual de sessões OPU que não produziram embriões na PIVE. Em todas as análises considerou-se nível de significância de 5%. Na comparação entre as raças, a Nelore apresentou maior média (p < 0,001) para número de oócitos, número de embriões e taxa de embriões, e menor percentual (p < 0,001) de sessões OPU/PIVE que não produziram embriões em comparação com a raça Gir. Na análise por quartis, houve aumento (p < 0,05) no número médio de oócitos e de embriões do quartil inferior para o superior dentro de cada raça. Na comparação dos quartis entre as raças, a raça Nelore apresentou valores superiores (p < 0,05) no número de oócitos, de embriões e na taxa de embriões em todos os quartis. O percentual de sessões de OPU/PIVE que não produziram embriões reduziu significativamente (p < 0,05) à medida que o nú-mero de oócitos aumentou nos quartis. Em conclusão, a raça Nelore apresentou maiores médias de oócitos, embriões e taxa de embriões em comparação à raça Gir. O número e percentual de sessões que não produziram embriões foram menores na raça Nelore. O maior número de oócitos reflete no aumento do número de embriões e na redução do número e percentual de sessões de OPU que não produziram embriões.

Authors: Lu Zheng , Wang Pei , Zhang Xiaodong
Published: April 2024

Logistics is playing a significant role in supporting economic growth and material security during the epidemic period and it has been  experiencing a rapid development in recent years. With the issues of personalisation and cost, the economy and society ask for higher requirements for logistics storage systems. The rational design of the functional area layout is an essential step to improve the operational efficiency of the logistics warehousing system. In reality, due to warehouse design and equipment application, there has been a gradual increase in irregular warehouses. By taking an irregular warehouse as an example, combining the operation status quo, this paper clarifies the functional area settings and constructs a 0–1 integer planning model based on the grid and systematic layout planning method with constraints, such as the unique functional attributes of the grid. We optimised the genetic algorithm based on the warehouse irregularity factor and the grids factor, and then solve it through MATLAB. Finally, by using the Flexsim software, simulation metrics were selected for evaluation, the method feasibility is verified.
Eco-Efficiency Evaluation of Integrated Transportation Hub Using Super-Efficiency EBM Model and Tobit Regressive Analysis – Case Study in China
Authors: Wang Ling , Wang Qi
Published: April 2024

The transportation industry is a key area for ecological civilisation construction and low-carbon development. As the core support of the  national integrated transportation system, the ecological development level of integrated transportation hub (ITH) is crucial for enhancing the sustainable development capacity of the national integrated transportation. An eco-efficiency evaluation index system of ITH is established  in this study and the eco-efficiencies of twenty international ITHs in China are comprehensively evaluated based on the super-efficient epsilon-based measure (EBM) model. Then the panel Tobit regression model is adopted to analyse the influencing factors of eco-efficiency. The results  show that the average eco-efficiency of ITHs in China during 2011–2021 declines first and then rises, with a relatively high level overall but not efficient yet, and there is an obvious gradient distribution characteristic in all eco-efficiencies. Among them, Guangzhou ranks first, followed by  Haikou, and Harbin ranks last. It is found that integrated transportation efficiency, urban green coverage, level of opening-up and economic development improve eco-efficiency significantly, while urbanisation rate, industrial structure and technology input have a negative impact. The  results are consistent with the actual situation, verifying the practicality of models, and can be used to promote the sustainable development of integrated transportation.
Towards Intercity Mobility System – Insights into the Spatial Interaction Gravity Model and Determination Approach
Authors: Wang Qinyu , Yu Weijie , Wang Wei , Hua Xuedong
Published: April 2024

The current development of urban agglomeration greatly promotes the intercity connection and elevates the significance of intercity mobility system. However, intercity mobility often exhibits extreme spatiotemporal imbalances due to the diverse urban characteristics. This poses a huge challenge for traffic management and reveals the necessity on understanding the urban attractiveness for intercity mobility, which is represented as spatial interaction gravity in this study. While recent works have explored relevant aspects, they failed to provide insights into temporal variations in spatial interaction gravity or capture the determining factors from multiple perspectives. To fill this gap, this study proposed a two-phase framework to measure the urban spatial interaction gravity and developed determination approaches utilising the large-scale location-based services (LBS) dataset. Specifically, the inverse gravity model was adopted for the measure within multiple urban agglomerations and city sets during weekdays, weekends and holidays. Then, we developed the fitting equations of spatial interaction gravity by incorporating the correlated features associated with social, economic, network accessibility and land use. The findings present spatial interaction gravity across different periods and substantiate the distinct determination effects of features, with a high fitting accuracy. They provide promising supports for the intercity mobility prediction and pre-emptive traffic management.
Prerequisites for Statistical Analyses of the Quality of Instrument Flight Procedures
Authors: Romanović Roman , Samardžić Kristina , Novak Doris
Published: April 2024

Instrument flight procedures are essential and critical components of the global aviation system. They are designed for all phases of flight, i.e.  the standard instrument departures, standard instrument arrivals, instrument approaches and the en-route phase of flight. Instrument flight procedures are designed from various aeronautical data, information, dimensions, etc., which are named instrument flight procedure elements according to this paper. Development of air navigation systems affect design of instrument flight procedures and flexible use of airspace. The design process is carried out within a framework defined by international and national standards, organizational norms and economic aspects. Instrument flight procedure elements are a fundamental part of the process. Deviations of these elements from full compliance with international regulations can significantly and negatively affect air traffic safety. The objective of this paper was to investigate the basic prerequisites for statistical analysis of the design quality of instrument flight procedures, which have not been explored before. Six prerequisites were proposed for acquiring the data and preparing them for further statistical use.
Yrkesfaglæreres profesjonsfaglige digitale kompetanse i et spenningsfelt mellom skole og arbeidsliv
Authors: Berntsen Svanhild , Lahn Leif Christian
Published: April 2024

Begrepet profesjonsfaglig digital kompetanse (PfDK) har fått gjennomslag i forskningslitteraturen om nye krav til læreres yrkeskompetanse i et digitalisert arbeidsliv. Imidlertid har denne forskningen i liten grad belyst hva PfDK kan innebære for yrkesfaglærere. Artikkelen tar utgangspunkt i et yrkesdidaktisk perspektiv på pedagogisk integrering av digitale ressurser for å fremme læring i en yrkesutdanning som veksler mellom opplæring i skole og arbeidsliv. En modell for yrkesfaglærernes PfDK, YFL-modellen, er utviklet med basis i denne forståelsen og blir i denne studien av ePortfolioer og digitale dokumentasjonssystemer i flere yrkesfag underkastet en eksplorerende validering.

Teoretisk plasseres studien i en sosiokulturell forståelse av læring hvor bruksområder og ulike formål for denne teknologien sees i lys av muligheter for læring på tvers av arenaer i samarbeid med andre aktører. Forskningsdesignet er inspirert av designbasert forskning der forskningsbaserte prinsipper for systemutforming implementeres i flere runder med lokalt utviklingsarbeid og tett samarbeid mellom forskere og praktikere. Datamaterialet er analysert tematisk og som integrerte slutninger i tråd med prinsipper for metodekombinert forskning. 

For å lykkes med teknologistøttede grensekryssingspraksiser viser resultatene, i lys av YFL-modellen, at yrkesfaglærere har behov for både profesjonsforankrede og fagintegrerte kompetanser. Dette viser seg eksempelvis i profesjonell kommunikasjon om yrkesdidaktiske formål for bruk av ePortfolioer, og i en mer innovativ og transformativ praksis når elever opprettet personlige læringsportfolier som kommuniserer yrkeskompetanse. Dette utfordrer yrkesfaglærerrollen ved å kreve en mer adaptiv pedagogisk tilnærming. En utvikling av PfDK i et bredt profesjonsperspektiv omfatter kompetansedimensjoner knyttet til andre aktørers holdninger til teknologi, samarbeidsmuligheter i utviklingen av de teknologiske systemer og i overvinnelse av organisatoriske og politiske hindringer. Videre forskning bør gjøre en systematisk studie av viktige dimensjoner i YFL-modellen i flere yrkesfag.

Formålet med denne studien er å utforske yrkesfaglærerstudenters erfaringer med massive open online courses (MOOCer) som digitale læringsressurser i yrkesfaglærerutdanningen. To forskningsspørsmål utforskes: 1) Hvilke potensialer og begrensninger oppfatter yrkesfaglærerstudenter at MOOCer som læringsressurs har i fag- og yrkesopplæring og yrkesfaglærerutdanning? 2) I lys av Digital Competence Framework for Educators (DigCompEdu), hvordan kan MOOCer styrke yrkesfaglærerstudenters profesjonsfaglige digitale kompetanse?
Datamaterialet består av arbeidskrav og refleksjonsnotater utarbeidet av 100 yrkesfaglærerstudenter ved yrkesfaglærerutdanningen etter å ha jobbet med MOOC. Dataene ble analysert i henhold til trinnene i refleksiv tematisk analyse.
Funnene ble sortert i tre overordnede kategorier: Potensialer, begrensninger og rammefaktorer. Potensialer beskrevet av yrkesfaglærerstudenter inkluderer fleksibilitet, variasjon, aktivitet, tilpasset opplæring, delbarhet og aktualitet, mens begrensninger som ble oppgitt var relatert til samspill, relasjonsbygging, praktiske ferdigheter, taus kunnskap, danning og fangbarhet. Rammefaktorer, slik som elevers og læreres forutsetninger og tilgang på økonomiske ressurser, ble oppfattet som både potensialer og begrensninger.
Funnene viser at bruk av MOOCer som digitale læringsressurser i yrkesfaglærerutdanningen har mange potensialer, men også flere begrensninger. Yrkesfaglærere må være bevisste på når, hvor og til hvilke formål MOOCer er gunstige læringsressurser. MOOCer kan ikke erstatte fysisk tilstedeværelse i yrkesfaglærerutdanningen og fag- og yrkesopplæring, men de kan være et verdifullt supplement. For å legge til rette for utvikling av elevenes digitale ferdigheter må yrkesfaglærerstudenter utvikle og styrke sin egen profesjonsfaglige digitale kompetanse. Til tross for at det europeiske rammeverket DigCompEdu har høstet kritikk for ikke å ivareta yrkesfagenes egenart, viser denne studien at DigCompEdu favner bredt og fanger opp mange sentrale aspekter ved den mangefasetterte digitale kompetansen yrkesfaglærere trenger for å utdanne fremtidens fagarbeidere til et mangfoldig arbeidsliv.

Financial distress identification remains an essential topic in the scientific literature due to its importance for society and the economy. The advancements in information technology and the escalating volume of stored data have led to the emergence of financial distress that transcends the realm of financial statements and its’ indicators (ratios). The feature space could be expanded by incorporating new perspectives on feature data categories such as macroeconomics, sectors, social, board, management, judicial incident, etc. However, the increased dimensionality results in sparse data and overfitted models. This study proposes a new approach for efficient financial distress classification assessment by combining dimensionality reduction and machine learning techniques. The proposed framework aims to identify a subset of features leading to the minimization of the loss function describing the financial distress in an enterprise. During the study, 15 dimensionality reduction techniques with different numbers of features and 17 machine-learning models were compared. Overall, 1,432 experiments were performed using Lithuanian enterprise data covering the period from 2015 to 2022. Results revealed that the artificial neural network (ANN) model with 30 ranked features identified using the Random Forest mean decreasing Gini (RF_MDG) feature selection technique provided the highest AUC score. Moreover, this study has introduced a novel approach for feature extraction, which could improve financial distress classification models.

Emergent chain-of-thought (CoT) reasoning capabilities promise to improve the performance and explainability of large language models (LLMs). However, uncertainties remain about how reasoning strategies formulated for previous model generations generalize to new model generations and different datasets. In this small-scale study, we compare different reasoning strategies induced by zero-shot prompting across six recently released LLMs (davinci-002, davinci-003, GPT-3.5-turbo, GPT-4, Flan-T5-xxl and Cohere command-xlarge). We test them on six question-answering datasets that require real-world knowledge application and logical verbal reasoning, including datasets from scientific and medical domains. Our findings demonstrate that while some variations in effectiveness occur, gains from CoT reasoning strategies remain robust across different models and datasets. GPT-4 benefits the most from current state-of-the-art reasoning strategies and performs best by applying a prompt previously discovered through automated discovery.

Published: April 2024

Background

Studies on the effects of aerobic exercise on working memory (WM) have mainly concentrated on the overall effects, yet there is little knowledge on how moderate intensity aerobic exercise impacts the sub-processes of verbal WM (VWM) in adolescents. To address this gap, two experiments were conducted to explore the influence of aerobic exercise on the maintenance and updating sub-processes of VWM.

Methods

In Experiment 1, a mixed experimental design of 2 (exercise habit: high vs. low) × 3 (memory load: 0-back vs. 1-back vs. 2-back) was used to compare VWM and its sub-processes in 40 adolescents. In Experiment 2, a 2 (group: intervention vs. control) × 3 (time point: pretest vs. 1st post-test vs. 18th post-test) × 3 (memory load: 0-back vs. 1-back vs. 2-back) mixed experimental design was used to investigate the acute and long-term effects of moderate intensity aerobic exercise on VWM and its sub-processes in 24 adolescents with low exercise habits.

Results

The results of Experiment 1 showed that VWM performance and its sub-processes in the high exercise habit group were better than those in the low exercise habit group. The results of Experiment 2 showed that the effects of the long-term exercise intervention were superior to those of the acute exercise intervention, and both were superior to the pretest. Meanwhile, it was found that aerobic exercise intervention had a greater effect size on the updating sub-process of VWM.

Conclusion

In conclusion, the results indicated that moderate intensity aerobic exercise could enhance the performance of VWM and its sub-processes in adolescents, and long-term intervention showed greater improvement effects compared to acute intervention, especially in the updating sub-process of VWM.

The study investigated the effects of construction waste powders exposed to elevated temperatures on the properties of cement mortar. The waste powders were obtained from demolished granite and clay blocks after more than 15 years of their service life. The exposure temperatures were 200 °C, 400 °C, 600 °C, and 800 °C. The heat-treated and untreated waste powders replaced cement in mortars at 10% and 20% by weight. The use of untreated recycled granite and clay powders adversely affected the mechanical strength and transport properties of the cementitious mixtures. On the other hand, the effects of thermal exposure varied for the two powder materials. As the exposure temperature increased, the performance of mixtures containing granite powder gradually deteriorated, while mixtures containing clay powder improved. The efficiency was both worst and best at 800 °C. For instance, a mixture containing 10% clay powder treated at 800 °C exhibited compressive strength equivalent to the reference mortar with no waste material. In contrast, under the same conditions, the compressive strength of the mixture containing granite powder was 33% lower. These results indicate that identifying the type and characteristics of recycled materials is essential for their utilization and application of enhancement methodsThe study investigated the effects of construction waste powders exposed to elevated temperatures on the properties of cement mortar.
