Published: November 2022

The aim of the paper consist in the synthesis of double substituted carbonated hydroxyapatite using Zn2+ and Mg2+ ions in comparison with the previous obtained Sr-Zn-CHAp. Fourier transform infrared spectroscopy, X-ray diffraction, environmental scanning electron microscope (ESEM) coupled with EDS is used to highlight the presence of the metallic ions into the apatite structure. Both inorganic compounds are tested as consolidants for two types of fir wood, young and 30-years old samples. The consolidation efficiency is demonstrated by colorimetric analysis, mechanical tests and the specific methods for water absorption behavior. Stronger specimens, especially of young wood, with no significant color differences, more hygroscopic and with higher hysteresis index result after treatment. In conclusion, carbonated hydroxyapatite double substituted with zinc, magnesium and strontium ions can be used in wood preservation-conservation techniques.

As a high priority for moving the sports industry forward, the sports market ecosystem requires the development of professional competencies and improving the entrepreneurship education of sports science students. During the last years, entrepreneurship has gained importance in the sports sector to maintain competitiveness. Thus, universities need to promote sports sciences students’ entrepreneurial competencies to improve employability. This research aimed to analyze the differences between first-year and fourth-year sports science students regarding the merit of professional competencies within entrepreneurship education. Both groups of students completed a set of tests presenting professional success factors. Cognitive abilities were measured with Intelligence Structure Battery (INSSV - Short Form, S2) and personality traits with Big Five Structure Inventory (BFSI, short-form, S1). Data were processed with confirmatory factor analysis and multigroup moderation analysis. The model showed acceptable fit indices (NFI=0.89, CFI=0.97, and RMSEA=0.08). The multigroup moderation analysis results indicated that the strongest effect on work aspects of the personality of the first-year sports science students comes from Conscientiousness (β=0.97), Openness (β=0.79), and Agreeableness (β=0.72). In contrast, this impact on fourth-year sports science students exists from Extraversion (β=0.85), Emotional stability (β=0.80), and Openness (β=0.80). On another side, an analysis of cognitive abilities revealed that the strongest effect was produced by numerical ability (β=0.94; β=0.84, respectively). The results demonstrated that sub-samples do not differ regarding the latent dimensions of human resources assessment. These results lead to necessary changes in the sports curriculum of the study program related to entrepreneurship education.
Democratic Design Through Play
Authors: van Leeuwen Lieselotte , Vaneycken Annelies , Paterson Catherine
Published: November 2022

The theoretical paper explores the question how designers and children can interact as peer citizens in participatory design (PD) processes. By discussing and integrating Mouritsen’s (2002) concept of child culture, approaches to child-citizenship and concepts of free play, we discuss how participatory design practices could stimulate child and adult cultures to permeate each other and by doing so, enable democratic interactions. Both children and adults are required to step away from their internalized normative ways of interaction. Adult designers are invited to also play and improvise whereas children are encouraged to play, but also to share responsibility for the process and outcome of PD sessions. The Ambiguity Approach (Vaneycken, 2020) is introduced as a methodological basis for more democratic PD practice with children. Two snapshots of PD processes illustrate the implementation of ambiguity of roles and ambiguity of materials respectively.
Multilingual Children’s Mathematical Engagement with Apps: What Can Be Learned from Multilingual Children’s Mathematical and Playful Participation when Interacting with Two Different Apps?
Authors: Christiansen Silje Fyllingsnes
Published: November 2022

The use of digital tools is becoming increasingly common in early childhood education. One key to using digital tools to enhance learning in children may lie in using them the way children tend to when given the choice: as play. This article examines and evaluates multilingual children’s mathematical engagement with digital apps, focusing specifically on what might be learned from multilingual children’s mathematical and playful participation when interacting with two different apps. Mathematical engagement is here defined by Alan Bishop’s six mathematical activities: counting, measuring, locating, designing, playing and explaining. Helenius et al.’s elaboration of mathematical play is used to connect the mathematical play to the play of children. Multilingual children’s interactions with digital apps have been video recorded in natural settings in a kindergarten. The findings show that playful digital apps do promote the children’s participation in mathematical activities, while apps that aim to provide a formal learning structure seem to promote neither play nor mathematical activities.

Authors: Feder Karen
Published: November 2022

This qualitative design research study looks at how children’s participation in the design process influences design students and their decisions when designing for play. The study analyses the experiences and reflections of 16 design students collaborating online with children around the world and identifies challenges and opportunities regarding this way of working. One case example illustrates how a design student (Paula) is able to acquire a better understanding of a child (Pedro) and his everyday life and uncover cultural challenges for the child’s opportunity to play. The article concludes on how a more balanced design process that includes collaboration with children can make design students become more aware of the cultural context they are designing for, leading to the potential of more child relevant play experiences.

Authors: SADLI SADLI , SALEHA SITTI , RAIYAN RAIYAN
Published: November 2022

Mushrooms contain a substance known as glutamic acid, that produce a savory taste which has the potential to be developed into a natural flavoring. The research began with the determination of amino acid levels in three phases of harvesting straw mushrooms, namely: the egg phase, the bud phase and the adult phase, by using High Performance Liquid Chromatography which aims to determine the harvesting phase with the highest glutamic acid content. The test results of amino acid levels showed the adult phase contained the highest glutamic acid levels of 49.08 mg/g. Furthermore, the manufacture of straw mushroom flour was performed with temperature variations of 60° C and 70° C and drying times of 6, 7 and 8 hours. Then the flavoring formulation was completed  by mixing mushroom flour and other dry additives namely shallots, garlic, white pepper, tapioca flour, salt and sugar. The resulting flavoring test is conducted using a description test by assessing the sensory properties of natural flavorings, namely color, aroma, taste and texture. Based on a panelist rating, F2 (60°C, 7 hours) has the best score for color (3.88) and aroma (3.32). F5 (70°C, 7 hours) has the best score for taste (3.24) and F1 (60°C, 6 hours) has the best score for texture (2.08). The conclusion of  this study is that mushrooms have a very high potential to be deformalized into natural flavorings, as well as the natural flavoring quality parameters of mushrooms is influenced significantly by temperature parameters and drying time

Published: November 2022

The capital investment in Aceh between 2010 and 2017 happens after the conflict and tsunami. Management of capital investment, its growth, and factors inhibiting capital investment after conflict and disaster are the focal points of this study. The purpose of this research is to determine how foreign investors in Aceh are protected under Law Number 25, 2007 and what types of security factors are present in Aceh. This research consisted of normative legal or library research. As normative legal research, only secondary data, which includes primary, secondary, and tertiary legal materials, were utilized. Based on the analysis, the Province of Aceh's management capital investment consisted of management governed by legislation governing Aceh's governance and legislation governing capital investment. In addition, the regional government of Aceh stipulated legislation governing capital investments. The growth of capital investment, both domestic and foreign, exhibited an increase, although it was not statistically significant. This slow growth was caused by security insurance, inadequate infrastructure, and the lack of legal certainty in conflict, earthquake, and tsunami-affected regions.
CHANGE OF BUSINESS ENTITY TO THE EXISTENCE OF BUSINESS LICENSE IN REALIZING LEGAL GUARANTEE AND EASY BUSINESS IN INDONESIA.
Authors: Yani Teuku Ahmad , Yahya Azhari , Abdurrahman Abdurrahman
Published: November 2022

The laws and regulations in Indonesia recognize various legal forms of companies; however, the legal form of a Limited Liability Company is considered to have better business prospects. Limited Liability Company also becomes a legal form of a company that can conduct business in all business fields. This condition has led to the practice of changing the legal form of companies in Indonesia from companies with certain legal forms to the legal form of Limited Liability Companies. This change in the legal form of the company is not covered by a special law that can combine the needs of changing the legal form of the company. In practice, this change in legal form is carried out in various ways that may result in legal uncertainty on one hand, and licensing difficulties as a result of a change in legal form on the other hand. Therefore, a new concept that can create legal certainty and ease doing of business in changing the legal form of companies in Indonesia is needed.

Authors: Fitri Rizky Aulia , Darmawan Darmawan , Saiful Teuku
Published: November 2022

This article examines the liability of land transportation providers for passengers' annoyance resulting from delays. Article 186 of the Traffic Law and Transportation Code obligated every public vehicle to transport passengers following an agreement. In reality, however, there were still businesses that were not meeting their obligations. The purpose of this study was to explain the causes of the delay and the company's liability as a result of the delay. This study employed empirical legal research methods and a sociological law perspective. The study revealed that the terminal operator's management of services was suboptimal, the drivers were unprofessional, the vehicle's engine malfunctioned, and passengers were picked up outside the terminal, but the land transportation companies that caused the delay were not responsible for their passengers and did not offer compensation. This case required the Service Unit Coordinator of the Bus Station in Banda Aceh to be resolute in following up on the Land Transportation Management Center's warnings to revoke the permits of irresponsible companies toward passengers due to their negligence.
TRANSITION TO A LOW CARBON ECONOMY IN ROMANI
Authors:   Bucharest University of Economic Studies, Romania, STĂNCIULESCU Raluca-Ioana
Published: November 2022

The EU Roadmap for moving to a competitive low carbon economy in 2050 states a potential of 85% emission reductions in industry by 2050. The industry is unlikely to meet this target without a major change in the policy frame. The purpose of this article is to assess the potential of the transition to a low carbon economy in Romania including a macroeconomic outlook and to offer some recommendations. Climate challenges rarely appear in the mass-media in Romania. There is no fundamental environmental education, and the media is uninterested in these issues because they do not sell. The environment receives only occasional attention; the primary concerns are about the energy supply and prices. Romania needs to increase knowledge transfer in this context. This change may be done by establishing tactics that combine techniques for reducing environmental impact and communicating the benefits of this process. At this time when innovation and sustainability are two of the most important key elements of the energy transition, it is more important than ever to maintain transparency and better consultation among all decision-makers by focusing on integrated efficiency issues that include economic, social, environmental, and climate change mitigation.

En esta investigación se evaluó la cinética de reducción de la turbidez inicial (1455 UNT) de aguas residuales de una industria curtiembre mediante la aplicación de biofloculantes directos elaborados a partir del alga Chondracanthus chamissoi (alginato) y de las mudas del crustáceo Emerita analoga (quitosano). Se recolecto el material biológico precursor en las playas de Lima, Perú, a partir de este material; se produjo ácido algínico fibroso y posteriormente alginato de sodio. Se usaron los procesos de desmineralización, desproteinización y posterior desacetilación para obtener el quitosano a partir de las mudas del crustáceo. Se evaluó el efecto del pH, la dosis de los biofloculantes, el tiempo de equilibrio del proceso. Además, se determinó el orden cinético de la velocidad de floculación mediante la prueba de jarras. Los resultados indicaron una remoción de la turbidez superior al 99 % dentro de los primeros 30 minutos para dosis de 0.2 a 2 g/l de floculantes y pH ácido (igual a 4); no se registraron diferencias significativas a distintos valores de pH (4-12) y dosis (0.2 a 2 g/l). El ajuste lineal entre el tiempo de floculación y la turbidez generó ecuaciones cinéticas significativas de primer orden para ambos floculantes con constantes de velocidad k1 del orden de 10-4 (1/NUT.min) y tiempos de reducción de la mitad de material particulado (vida media: τ1/2) inferiores a los 10 minutos. Esto se puede considerar como un criterio para medir la eficiencia del proceso de floculación directa en el tratamiento de aguas industriales de curtiembre.

El uso de biomasa como adsorbente constituye una alternativa potencial para la remoción de metales pesados presentes en aguas residuales industriales, lo cual representa un alto riesgo para el medio ambiente. En este trabajo se realizó la adsorción de Pb+2 y Cd+2 utilizando la cáscara de cacao como adsorbente en columnas y la simulación dinámica del proceso utilizando el software Aspen Adsorption® V10, con la finalidad de validar los resultados de la simulación y los obtenidos experimentalmente. Las curvas de ruptura del simulador y las experimentales convergen en casi toda la trayectoria, existiendo ligeras variaciones en el tramo final de la curva, coincidiendo los tiempos de ruptura para ambos metales, dando coeficientes de correlación (R2) de 0.984 y 0.998 para el Pb+2 y Cd+2, respectivamente, así como valores de error (SSE) inferiores al 5 %. Se analizó el efecto que produce la variación de la altura del lecho y el caudal en las curvas de ruptura; a medida que aumenta la altura del lecho y disminuye el caudal aumenta el tiempo de ruptura, favoreciendo la adsorción de ambos metales. Los resultados de esta investigación muestran la importancia del uso del software Aspen Adsorption® en el proceso de biosorción debido a la similitud con resultados experimentales, proporcionando su uso un ahorro de tiempo y recursos.

Waterbody evaporation (E) within endorheic basins in semiarid areas is critical in determining the water balance. Accurate E measurements can provide valuable information for the sustainable management of water resources in the face of climate change scenarios. However, evaporation can be estimated through methods as efficient as Penman using variables from agroclimatic stations, such as wind velocity, net radiation, relative humidity, and air temperature, which have spatiotemporal variability. Within the evaporation models based on remote sensing (RS) is the surface energy balance model (SEB), which has been applied to different methodologies and extends the measurements of evapotranspiration (ET) at a regional level. SEB-based methodologies use physical principles with minimal weather data requirements to estimate ET. Hence, this article compares two RS methodologies that estimate evaporation: The Regional Evapotranspiration Estimate Model (REEM) and the Earth Engine Evapotranspiration Flux (EEFlux). Comparing ET measurements obtained from REEM and EEFlux for seven Landsat OLI scenes in the agriculture cycle of April to September applied against the simplified Penman equation showed that the REEM performed better (d = 94 %) than the EEFlux (d = 68 %) for the indicated period. Although the comparison of REEM and EEFlux shows accurate E measurements (REEM), gridded weather data (EEFlux) needs to improve, increasing the scale using local information.

This study aims to understand the role of key drivers of historical changes in the shoreline and its implications with the erosion risk in the northern coastal strip of the state of Sinaloa, located on the east coast of the Gulf of California. Digital maps from different years (1981, 1991, 2004, and 2018) are analyzed using geographic information system software (DSAS and CERA) to examine: (a) the movement and rate of the shoreline change; and (b) the potential vulnerability consequences, and erosion risk. The obtained results indicate that between 1981 and 2018: (a) anthropogenic actions (dams and breakwaters) were the main drivers of both the shoreline changes and the environmental damage underlying the erosion risk that has occurred in recent decades; (b) the coastline of the study area has been eroding with an average EPR of -3.1 m per year, which has led to an average NSM of -112.9 m; and (c) the risk of erosion remained moderate, although the vulnerability increased from a moderate to a high level and potential consequences from a very low to a moderate level. Besides, the results of this study provide a basis for future analyses focused on predicting shoreline changes and coastal risk.

En este trabajo se analiza cómo se desarrollan y construyen socialmente las inundaciones del sur de la ciudad de San Luis Potosí, México, y se evidencian las estrategias locales para hacerles frente. Para esto se examinan los discursos sobre el comportamiento de las lluvias en el área de estudio, y se estudian las políticas de urbanización del sur de la ciudad en la década de 1970 y 1980, además del patrón de poblamiento de la ciudad. En segundo lugar, se examina la organización social y comunitaria urbana a través de prácticas locales en el fraccionamiento El Aguaje para prevenir y enfrentar la inundación, las cuales son relegadas o rechazadas por las autoridades gubernamentales por considerarlas poco prácticas y sin sustento técnico. Los resultados de la investigación muestran cómo se construyen estos espacios urbanos como riesgosos para la población en un proceso de diversos tiempos y espacios sociales, políticos y económicos; de esta manera, el contexto de privatización de la tierra, la industrialización y la amplia desigualdad social y económica han propiciado la generación de espacio riesgoso ante inundaciones en El Aguaje. Además, la investigación evidencia el actuar local para enfrentar las inundaciones y resguardar su salud y patrimonio, el cual va de modificaciones a las calles y casas a la organización para demandar solución a las autoridades.

Las crecientes que ocurren en nuestro país cada año generan daños y ponen en peligro a los embalses, cuyo dimensionamiento hidrológico está basado en el hidrograma de la creciente de diseño. La estimación más simple de tal hidrograma se basa en el análisis de frecuencias conjunto del gasto pico y volumen anuales. En este estudio se ajustó la distribución general de valores extremos bivariada (GVEb), al registro de 55 crecientes anuales en la estación hidrométrica La Cuña, sobre el Río Verde de la Región Hidrológica No. 12-3, México. Este proceso abarca nueve etapas: (1) selección y prueba de los registros anuales; (2) verificación de su aleatoriedad; (3) estimación de las probabilidades empíricas conjuntas; (4) ajuste de la función GVEb a través del método de máxima verosimilitud; (5) validación de la función GVEb; (6) ratificación de las marginales GVE; (7) verificación de las restricciones de probabilidad; (8) estimación de eventos de diseño univariados híbridos, y (9) estimación de eventos de diseño conjuntos y selección del subgrupo crítico. En la etapa 1 se aplica un test simple de la GVE. La etapa 2 se realiza con base en el Test de Wald-Wolfowitz. En la etapa 4 se emplea el algoritmo Complex. Las etapas 5 y 6 utilizan el Test de Kolmogorov–Smirnov. En la etapa 9 se usan las gráficas del periodo de retorno conjunto de tipo AND. Por último, se formulan las conclusiones, las cuales destacan el enfoque de maximización adoptado y las ventajas de aplicar la GVEb.

Marka yellow box junction (YBJ) adalah marka kotak kuning dengan dua garis diagonal berpotongan yang berfungsi untuk melarang kendaraan berhenti di area persimpangan agar tidak terjadi kemacetan. Namun dalam penerapannya, masih banyak pengendara melakukan pelanggaran marka YBJ sehingga gridlock sering terjadi di persimpangan, khususnya di kota besar seperti Surabaya. Untuk itu dilakukan penelitian untuk mengetahui keefektivitasan marka YBJ terhadap kinerja simpang, hubungan keberadaan marka YBJ terhadap keefektivitasan kinerja simpang, kesesuaian standar YBJ, dan pengetahuan pengendara terhadap marka YBJ di Surabaya. Simpang Jl. Margomulyo - Jl. Tandes Lor dianggap dapat menjadi parameter untuk kinerja simpang, dan tingkat pelanggaran marka YBJ. Dilakukan juga pengecekan kesesuaian standar pembagian kuisioner tingkat pengetahuan pengendara di Surabaya terhadap YBJ, dengan menggunakan metode analisis koefisien korelasi dengan bantuan software SPSS 26. Dari hasil keefektivitasanYBJ terhadap kinerja simpang, diperoleh hasil tidak efektif dengan angka tundaan sebesar 45.72 det/skr, dan tingkat pelayanan simpang E. Dari analisa hubungan, diperoleh hubungan yang erat antara keberadaan YBJ dengan kinerja simpang. Dari hasil survei kesesuaianYBJ dengan peraturan, diperoleh adanya ketidak sesuaian dimensi dengan peraturan yang berlaku, sehingga kesesuaian YBJ adalah tidak efektf. Dari hasil survei tingkat pengetahuan YBJ diperoleh tingkat pengetahuan pengendara terhadap definisi, dan fungsi YBJ adalah cukup baik, akan tetapi banyak pengendara masih belum mengetahui sanksi pelanggaran YBJ karena sangat kurangnya sosialisasi dari Pemerintah Surabaya.

Diabetes melitus adalah gangguan metabolik kronis yang ditandai dengan hiperglikemia atau tingginya glukosa dalam darah karena gangguan dalam sekresi maupun respons terhadap hormon insulin. Menurut data dari International Diabetes Federation, prevalensi diabetes melitus di seluruh dunia sudah sangat tinggi, yaitu 537 juta pada tahun 2021. Akan tetapi, sudah ada berbagai obat alternatif alami yang dapat digunakan untuk menangani penyakit tersebut. Dalam beberapa penelitian, banyak tanaman yang sudah teruji khasiatnya sebagai obat antidiabetes alami karena kandungan fitokimianya. Studi literature review ini dilakukan dengan pencarian data melalui Google Scholar dan Science Direct dalam kurun  waktu 10 tahun terakhir (2013-2022). Dari 29 artikel yang sesuai diperoleh hasil bahwa beberapa kandungan fitokimia pada tumbuhan seperti alkaloid dengan kemampuannya memperbaiki sel beta pankreas, flavonoid sebagai astringen, saponin dengan kemampuannya menstimulasi sekresi insulin dari sel beta pankreas, dan tanin sebagai antioksidan alami berpotensi menurunkan glukosa darah pada diabetes melitus tipe 1 dan 2.

Published: November 2022

El presente capítulo centra su atención en la necesidad tácita de la institución militar de describir e identificar los símbolos, hitos y protagonistas del conflicto armado en la historia reciente de Colombia que deben tenerse en cuenta y estructurarse para obtener un proceso efectivo y favorable en la interpretación de la guerra y la construcción de una memoria histórica que permita la interiorización de una idea mítica de las Fuerzas Militares en la opinión pública. Tomando como punto de partida los orígenes de la guerra y el Estado, hasta llegar a la percepción que tiene la sociedad de estos conceptos y cómo eso puede ser significa-tivo al momento del balance de los resultados (hablando de la victoria misma), el contenido se desarrolla mediante un análisis histórico des-criptivo, el cual tiene como contexto el origen de la guerra, la necesidad de la guerra, la igualdad moral, el concepto político de la guerra justa (jus ad bellum) y su influencia posterior en la construcción de relaciones internacionales y avances estratégicos en las Fuerzas Militares.

En este documento se describe que, en la última década del siglo XX, Colombia sufría una grave desestabilidad gubernamental a causa del control y la manipulación terrorista efectuada por las Fuerzas Arma-das Revolucionarias de Colombia (FARC). Tras el escalamiento bélico del conflicto y la amenaza de una toma inminente del poder con el cerco a Bogotá, el Ejército Nacional planeó y ejecutó la operación Libertad I, la cual desarticuló la intención militar y política de las FARC y se constituyó en el éxito militar que dio inicio al declive y la decadencia de esta organización armada. Desde un enfoque mítico, se muestra que la operación Libertad I otorgó una máxima legitimidad al Ejército Nacional por parte del pueblo colombiano.
