Authors: GÜNEY Deniz , ATAR Fahrettin , TURNA İbrahim , BAYRAKTAR Ali
Published: December 2022

Scotch pine is a primary species that spreads from sea level to very high altitudes in Turkey and has a very wide distribution area in the world. For this reason, it is important to investigate the variations of the species depending on the altitude. The research aims to determine the morphogenetic variations of the seedling characters in populations representing the vertical distribution area of Scotch pine and to reveal the within and among population variations in the vertical distribution areas. In the study, seedlings (three, four and five-year-old) grown from the seeds collected from five populations in the altitudinal zones up to 2,250 m from sea level in the natural distribution area of Scotch pine in Trabzon region were used. The seedling’s height, root collar diameter, the number of side branches and crown buds and sturdiness quotient were determined. As a result of the study, it was determined that there were statistically significant differences (p

The article presents the results of a study on the influence of carbon sources, such as carbohydrates and sugar alcohols, on the growth and pigmentation of the Arthrobacter agilis wb28 strain isolated from wheat bran. Nutrient media were seeded with A. agilis wb28 cells by pricking. The cultivation of the strain was carried out at a temperature of 28 ± 1°C for 7 days. The presence of growth was determined by the turbidity of the medium, film and gas formation. It was shown that A. agilis wb28 cells are able to consume agar-agar components as the sole carbon source and synthesize metabolites that shift the pH of the medium to the alkaline region on Hiss medium, which is designed to assess the saccharolytic ability of microorganisms. It was found that the alkalinization of the medium during the growth of the A. agilis wb28 strain is characteristic in the presence of mainly oligosaccharides, polysaccharide, and sugar alcohol, with the exception of fructose monosaccharide. Media containing monosaccharides, such as glucose, arabinose, xylose, and galactose are not effective for the development of the A. agilis wb28 strain and pigment formation. As a result of the cultivation of the A. agilis wb28 strain on media with rhamnose and mannitol, acidification occurs, with it being more pronounced on the medium with mannitol. Pigmentation is also more pronounced on the medium with mannitol. The studied strain of A. agilis wb28 develops in the presence of glucose and fructose in comparison with the known strains of the genus Arthrobacter – pigment-formers, and to a greater extent forms a pigment on a medium with fructose. Gas formation during cultivation of the studied strain on all media used was not detected. More preferred carbohydrate sources for pigment formation by A. agilis wb28 are the disaccharides sucrose, lactose, maltose, fructose monosaccharide, and raffinose trisaccharide.

Authors:   Taras Shevchenko national University of Kyiv, Yuriev О.
Published: December 2022

In the article are discussed scientific research on the theory of significance of combat forces and the activity process in terms of nature, structure and concept of command and control readiness of future officers of the Armed Forces of Ukraine in modern warfare in the system of military education today and their practical importance in the formation of knowledge, skills and competencies of command and control readiness of future officers. The command and control readiness of future officers of the Armed Forces of Ukraine in the educational process of command and control training of the military form the basis for the formation of a high military professionalism, which has the following components: system of professional knowledge and skills in military unit management, training and education of the subordinate personnel; system of behavioural skills; system of moral and psychological skills. This research article theoretically defines the command and control readiness of future officers of the Armed Forces of Ukraine in the modern conditions of warfare and its practical importance for the officers when they perform socially important professional duties. To formulate command and control readiness of future officers of the Armed Forces of Ukraine in the modern warfare, the scientific article practically defines the importance of creating a professionally-oriented educational environment at military educational institutions and military facilities. The importance of creating a professionally oriented educational environment in higher military educational institutions and military training units of higher education institutions. Command and control readiness of an officer of the Armed Forces of Ukraine implies the presence of the appropriate level of physical health, formation and development of physical qualities necessary for successful professional activity, the presence of the appropriate level of physical culture of the person. This is obvious, because any professional activity of military service personnel requires that a particular level of application of physical strength by the person, physical energy is associated with the expenditure of not only mental but also physical energy in the process of fulfilling their professionally significant duties both in peacetime and in warfare. The future officer of the Armed Forces of Ukraine for the formation of command and control readiness in the process of training in higher military educational institutions and military educational units of higher education institutions must be trained in the general theoretical foundations of the disciplines, the main goal of the program is to provide the students with the knowledge and skills necessary for their command and control training, scientific, methodological, organizational and pedagogical skills.
Territorial Structure of Municipal Government at the Present Stage
Authors: Zabelina E. P.
Published: December 2022

The paper analyzes federal constitutional laws concerning the entry into the Russian Federation of its new constituent entities — Donetsk and Lugansk People’s Republics, Zaporozhye and Kherson regions — in terms of regulating territorial organization of local self-government. The author analyzes upcoming transformations, makes and justifies proposals regarding the need to expand the system of municipalities in new constituent entitties of the Russian Federation by including settlements as its local self-government territories. The implementation of such a provision will comply with Federal Law No. 131-FZ dated 06.10.2003 «On General Principles of Organization of Local Self-Government in the Russian Federation» and will allow the population of rural and other settlements to participate more actively in local self-government.

The paper describes the principles of the territorial basis of local self-government and clarifies the possibilities of their preservation in the conditions of the ongoing transformations of local self-government, due to the introduction of amendments to the Constitution of the Russian Federation in 2020. The author characterizes the procedures fixed in the legislation for ensuring changes in the boundaries of municipalities, transformation and abolition of municipalities, analyzes the norms of relevant laws of constituent entitties of the Russian Federation and municipal legal acts specifying the procedure for solving territorial issues of local self-government, illustrates the process of consolidation of municipalities on the example of the Moscow region. It is noted that in the Russian Federation there is a three-level legal regulation of the municipal-territorial structure, including federal and regional legislation and municipal legal acts. This makes it possible to determine substantive powers of public authorities in this area of local self-government and establish the procedure for their enforcement. Taking into account the results obtained, draft Federal Law No. 40361-8 «On general principles of organization of local self-government in the unified system of public authority» is analyzed in order to identify the degree of stability of the existing system of territorial organization of local self-government. The author summarizes that adoption of the enactment under consideration will not entail significant changes, its principles and will not change the procedure for resolving issues of territorial organization of municipal power.
Declared and True Goals of Criminal Punishment
Authors: Maslov V. A.
Published: December 2022

The goals of punishment, enshrined in Part 2 of Article 43 of the Criminal Code of the Russian Federation, should actually act as one of the key guidelines for the law enforcement officer when individualizing punishment. At the same time, the existing construction is rightly criticized as abstract and devoid of practical meaning. The purpose of the paper is to develop recommendations for improving criminal legislation in terms of regulating practice-oriented goals of punishment. To achieve this goal, the author has substantiated inappropriateness of attributing norms on the purposes of punishment to declarative norms, demonstarted incorrectness of specifying restoration of social justice and prevention of new crimes as the goals of punishment, explained stable failure to fulfill the goal of correcting convicts with due regard to indicators in Russia (from 2008 to 2021), highlighted the approach based on the expediency of normative consolidation of two goals of punishment (taking into account the requirements of unification (correlation with the tasks of the Criminal Code of the Russian Federation), and focused on possibilities and expected results), namely, unconditional and complete restoration of the rights violated by the crime and correction of convicts. Taking into account pecularities of the existing system of types of punishment that actually makes the first of these goals unattainable, the author proposes to adjust norms regulating certain types of punishment (in essence, restorative principles should be referred to as exclusively fiscal in nature as existing punishments): priority compensation for damage caused to the victim, and only with full (or maximum possible in specific circumstances) compensation for all violated rights of the victim compensation to the State budget. The author argues that the goal of correcting a convicted person, despite being difficult to achieve (especially by criminal legal means), is necessary because it has regulatory potential.
Libro álbum y enseñanza del inglés como lengua extranjera. Un estudio piloto sobre creencias docentes
Authors: Laliena Cantero Daniel , Tabernero Rosa , Yebra José M.
Published: December 2022

Numerosas investigaciones han estudiado la utilidad de la literatura auténtica para la enseñanza de lenguas extranjeras, pero pocas han investigado el pensamiento docente sobre la viabilidad de la aplicación del género concreto del libro álbum para la enseñanza del inglés como lengua extranjera. El objetivo de este estudio de corte cualitativo era analizar las creencias de cuatro docentes en relación con la selección de obras literarias para el aula de inglés y con la viabilidad del libro álbum para tal fin. Se realizó un análisis categorial inductivo de la información recogida mediante entrevistas semiestructuradas. Los resultados mostraron que la posibilidad de trabajar sobre contenidos lingüísticos concretos era uno de los principales criterios que orientaban la selección y el uso de libros en el aula. Además, las participantes valoraron la dificultad cognitiva asociada a ciertos rasgos literarios del álbum contemporáneo como un obstáculo para su implementación en el aula de inglés. Así, la indagación sobre de las creencias de las docentes participantes demostró que privilegiaban el uso de literatura infantil para la promoción de la alfabetización funcional en inglés, pero no contemplaban usarla para trabajar la alfabetización literaria o las habilidades cognitivas de los alumnos en el aula de inglés.
De iure y de facto: Las dos caras del Consejo Europeo tras Lisboa
Authors: Martinez Sierra José Manuel
Published: December 2022

Este trabajo aporta una visión novedosa del Consejo Europeo, presentada en dos partes diferenciadas e interrelacionadas. La primera, el análisis de iure, analiza las disposiciones esenciales del derecho originario que conforman el marco de competencias del Consejo Europeo según la última reforma del Tratado de Lisboa. La segunda, el análisis de facto, analiza las superaciones y vulneraciones del predicho marco competencial por parte de los líderes europeos durante las cinco crisis de la UE: la crisis económica, la crisis migratoria, el Brexit, la COVID y la guerra de Ucrania. Algunas de las crisis mencionadas evidencian que el Consejo Europeo ha superado su marco competencial y vulnerado el derecho comunitario, posicionando al resto de instituciones como colaboradores necesarios. Las conclusiones principales son tres. Primera, el Consejo Europeo, tras el Tratado de Lisboa, es a la sazón el principal «poder» constituyente y constituido en la UE, ejerciendo las competencias clave, siendo la institución esencial para avanzar en el proceso de integración. Segunda, estudiadas las crisis referidas, hay evidencias de que el Consejo Europeo ha superado conscientemente el marco del derecho comunitario, no basándose en los marcos legales existentes, sino, en una voluntad clara de evitar el control político o jurídico cuando considera que las crisis lo requieren. La tercera conclusión, nos permite afirmar que el resto de las instituciones, incluido el TJUE, han dado cobertura a dicho proceder.

Analysis of the Textile and Clothing Industry Global Value Chains
Authors: Fernandez-Stark Karina , Bamber Penny , Couto Vivian
Published: December 2022

The textile and apparel industry is a highly globalized, multi-trillion-dollar sector. Today, production networks are dominated by low-cost Asian countries with very large labor-pools, which has made it increasingly difficult for other producers around the world to compete, including those in Latin America and the Caribbean (LAC). While the region has participated in the industry, there are currently no LAC countries amongst the leading ten exporters. The COVID-19 pandemic, together with rising geopolitical tensions between the US and China, however, has disrupted this well-established business model over the past two to three years. This creates the most significant opportunity of the past decade to reconfigure the geography of the supply chain; as a small, but long-term supplier, with proximity to the worlds largest single market, Central America is well-positioned to benefit from these changes. Nonetheless, the region needs to upgrade various aspects of their GVC participation in order to become a serious contender in the reconfiguration of the industry. Key policies should focus on developing human capital through industry-specific training initiatives; intensifying investment attraction efforts; and aggressively investing in both hard and soft infrastructure to reduce barriers to trade and enhance lead time responsiveness.

Published: December 2022

El mercado laboral venezolano ha sido afectado en los últimos años por el colapso económico, la hiperinflación y leyes que tienen efectos perjudiciales en la productividad y movilidad laboral. La participación laboral de Venezuela es una de las más bajas de América Latina y ha habido un aumento en la informalidad. El bajo nivel de salarios tiene un impacto en la capacidad de adquirir bienes y servicios y, por lo tanto, en las condiciones de vida de los venezolanos. Este estudio evalúa la evolución de la tasa de ocupación, desocupación y salarios en Venezuela durante el período 2020-2021 y también introduce el ndice de Remuneraciones de Alta Frecuencia (IRE-AF) para medir la evolución de las remuneraciones en el sector de comercio y servicios en el área Metropolitana de Caracas. Los resultados muestran una caída anual del 6,8% en la población económicamente activa, con una tasa de actividad que ha pasado del 58,7% al 53,8%, y una tasa de desempleo del 40,3%. También se observa una dolarización creciente de las remuneraciones y transacciones en el AMC.
Women’s informal labor market participation in Ecuador
Authors: Mahé Clotilde , Zanoni Wladimir , Oliveri María Laura
Published: December 2022

This paper describes trends, correlates, and critical patterns driving women's labor force participation in Ecuador between 2015 and 2021. We aim to understand better what factors cause women to choose to work in the informal sector in that country. To do that, we process data from seven waves (2015 to 2021) of the Ecuadorian National Survey of Employment and Unemployment. We document changes through time in female employment trends, and isolate key patterns of the statistical associations between household characteristics and those trends. We found an increase in the share of 15-year-old or older women who were active and occupied, as well as an increase in their holding of informal jobs. In addition, OLS estimates point to working informally as a second-best strategy where women -economically constrained, low-skilled agents- substitute for formal employment, opting for informal jobs when facing obstacles in meeting basic needs.

Authors: Jaimovich Analia , Elacqua Gregory , Rodríguez Silva Julio , Ortiz Guerrero Marcela , Schwartz Liora , Román Alonso
Published: December 2022

En años recientes, Chile ha incrementado sustantivamente su inversión en educación, producto de un crecimiento significativo tanto del gasto público como privado. Así, por ejemplo, mientras en 2004 los recursos públicos y los privados destinados a educación representaban un 2,6% y un 2,5% del PIB, respectivamente, hacia 2013 éstos habían aumentado a 5,7% y 3,0% (Santiago et al, 2017). Este reporte analiza la forma en que los recursos públicos son distribuidos en el sistema, entre establecimientos y entre sostenedores. Para ello, se enfoca principalmente en el financiamiento del sistema escolar a través de las subvenciones, evaluando las consecuencias distributivas del actual mecanismo de distribución de recursos en tres dimensiones: adecuación de recursos, equidad en la distribución de recursos, y planificación y administración de los recursos.

Published: December 2022

Regímenes federales como Brasil poseen importantes desafíos institucionales en el que administradores estatales y municipales comparten responsabilidades por la educación en un mismo territorio. En el año 2017, siguiendo el modelo del estado de Ceará, la gobernación del estado de Espíritu Santo formaliza por medio de una iniciativa legal el Pacto por el Aprendizaje de Espíritu Santo (PAES), un instrumento de coordinación estado-municipios en pos de objetivos de mejora sistémicos. El programa consistió en distintos ejes de acción que consideraron la consolidación de equipos en el nivel local que pudiesen liderar los regímenes de colaboración, la elaboración de directrices curriculares de enseñanza básica en torno a las cuales se realizaron instancias de formación continua a docentes y se elaboraron materiales tanto para docentes como para estudiantes; la generación de mecanismos de monitoreo y gestión de indicadores y objetivos de calidad educativa en las redes municipales, y, por último, la reorganización de la oferta educativa en los municipios. En el presente estudio se describe el detalle de este régimen de colaboración de Espíritu Santo, dando cuenta de su organización y gobernanza. En un contexto de alto nivel de complejidad institucional, instancias de colaboración y articulación que han logrado un alto porcentaje de participación de los distintos actores del sistema, representan una experiencia innovadora de estudio y aprendizaje para contextos similares. La nota técnica examina las tensiones que han acompañado la implementación y readecuación del PAES en un escenario de cambios en los ciclos políticos. Por último, se destacan las oportunidades de mejora que posee el PAES, destacando dos claves: 1) Profundizar su vinculación en la gobernanza política y programática del estado, buscando acentuar la responsabilización y rendición de cuentas. 2) Robustecer el rol y atribuciones de los niveles regionales del estado en el apoyo, monitoreo y seguimiento del PAES en la estructura municipal.
The Copernican Revolution as a Spatial Methaphor
Authors: MEDOVA ANASTASIYA
Published: December 2022

The author specifies the origin of the terms “Copernican Upheaval” and “Copernican Revolution” considering the spatial interpretations of this philosophical metaphor, which was evoked by the Kantian analogy between his model of knowledge process and the model of the solar system by Copernicus. On the base of Solomon Maimon’s criticism and subsequent scientific discussion, the author studies the analogy between a rotation of celestial bodies and the conformity of objects to knowing reason. As the result, the author offers two approaches to the interpretation of the spatial analogy of the Copernican Revolution. 1) As the analogy of mobility (plasticity) and immobility (immutability) of celestial bodies / reason in relation to knowable objects. 2) As the analogy of relativity and absoluteness of movement / cognition, leads to the question of the starting point and direction of predication in cognitive trajectories.
Amartya Sen & George Anastaplo on Literature, Law, and the Idea of Justice
Authors: Majeske Andrew
Published: December 2022

Both Professor Anastaplo and Professor Sen would agree that a crisis regarding justice exists in the contemporary world. Each of these scholars has endeavored in their work to address this crisis, in one way or another. For Professor Sen, the crisis is global in scope, and its solution also needs to be global. For Professor Anastaplo, the crisis of justice is local, and situatied in the West, and is a consequence of the break from the Western classical tradition of political philosophy and the way it treated justice, a break for which Niccolò Machiavelli can be considered initially responsible. This essay contrasts the thought of these preeminent scholars on justice, without attempting to prefer one's view over the other.

Defenders of Racial Justice
Authors: Thomas Brook
Published: December 2022

The best way to explore the confluence of law and literature from ratification of the Reconstruction amendments to Plessy is to focus on the career of a little known figure, the lawyer-novelist Albion W. Tourgée, and his relationship to Samuel Phillips, a lawyer who would become the second Solicitor General of the United States. This essay traces their efforts to achieve some semblance of racial justice in the post bellum South, and how eventually these two came to defend Homer Plessy in the infamous Plessy v Ferguson case (which established the separate but equal doctrine). In examining Plessy, this essay reveals how the structure of that defense could be traced to Tourgée's fiction, and how their defense, and its echoes, which extend to Brown v Board of Education and beyond, help to prove the old adage that truth often proves to be stranger than fiction.

Published: December 2022

Society 5.0 is a plan to generate a human-focused society that focuses on economic and social growth in Japan. The idea emerged as an evolution of Industrial Revolution 4.0, which is thought to have the capacity to revolutionize technology. One of the main features of Society 5.0 is the use of artificial intelligence. Artificial intelligence brings many benefits to various fields. One of them is in the field of education. Many studies claim that artificial intelligence can help ease human work and increase knowledge and skills in the field of education. Artificial intelligence has introduced fundamental challenges to education for students, educators and parents. But they are indirectly forced to use AI to learn. This is a solution, as well as a new problem that the education community must immediately adapt. Artificial intelligence has already become a part of education at high schools and colleges. However, at the kindergarten level, it is rarely used. On average, students at this level already have an AI-powered device at home. This study focuses on the role of artificial intelligence at the kindergarten level. This study recommends the importance of AI education at the kindergarten level to instill Artificial Intelligence skills in children from an early age, prepare them for the future of a digitalized world, and improve their computational and problem-solving abilities with artificial intelligence.

Defining KMS features in government institutions can be conducted by identifying the KM process is represented by some indicators. Many studies have been done in developing the KM system in various sectors. However, research on the KM system in human capital management has not yet been much published. This research aims to define a priority order of knowledge management process and identify knowledge management system features for Government Human Capital Management. Data collection has been done by distributing questionnaires (253 respondents) and interviewing stakeholders (9 experts) of the institution for human capital management in Indonesia (KemenPAN&RB, BKN, and LAN. We used three analysis methods: the Analytical Hierarchy Process (AHP), Pearson Correlation (Pearsonâ€™s R), and the Expert Judgment method. As a result, we found major features of KM system for HCM in Indonesia, including electronic group discussion (best practice and lesson learn), work performance evaluation (daily activities and profile), communication tools (e-mail, chat and video conference), document management (digital document and physical document) and expertise management (decision support, expertise locator and expert knowledge). The limitation of this study is the topic of research specific to the KM system for government human capital management in Indonesia. The object research only three government ministries appointed to be government human capital management managers. Recommendation KM system in the government institution must be implemented to facilitate KM process align with the organizational strategy and objectives.
Employing Several Methods to Estimate the Generalized Liu Parameter in Multiple Linear Regression Model
Authors: Alsharabi Najlaa Saad Ibrahim , Al-Mola Rasha Raad , Slewa Yonan Rehad Emad , Algamal Zakariya Yahya
Published: December 2022

Multiple linear interferences are a fundamental obstacle in many standard models. This problem appears as a result of linear relationships between two explanatory variables or more. Simulation results show that the generalized Liu regression model was the best and that the contraction parameter proposed was more efficient than the methods presented. As the error variance increases, the value (MSE) increases. When this problem exists in the data, the estimator of the ordinary least squares method will fail because one of the basic assumptions of the method has not been fulfilled. The normal least squares, which state that there is no linear correlation between the explanatory variables, will not get an estimator with the Best Linear Unbiased Estimator (BLUE) feature. The least-squares regression method and the generalized Liu regression method were compared by taking several methods for the generalized Liu parameters and selecting the best contraction parameter for the Liu regression model. The study aims to address the problem of multiple linear interferences by using the general Liu estimator and making a comparison between the methods for estimating the Liu parameter, where several methods were presented, and the best method for estimating the Liu parameter was chosen according to the standard of the sum of error squares as well as a comparison between these methods and the conventional method. Simulation results showed that the generalized Liu coefficient estimate was the best for having the lowest values (MSE) and that the best shrinkage parameter is (G4), the work-based approach.

The production of chirimoya (Annona cherimola Mill) is seasonal; therefore, the fruit's prices and availability are compromised. This research aimed to develop technologies to improve the production and competitiveness of off-season chirimoya fruit production. This research was conducted in the subtropical valley of Tumbaco, Pichincha province, Ecuador. Chemical defoliants (zinc sulfate, hydrogenated cyanamide, and copper chelate) and a sprouting inducer (hydrogenated cyanamide) were evaluated to standardize and increase defoliation improve sprouting, and consequently bring the harvest season forward. The study was conducted on eight-year-old trees of San JosÃ© de Minas and MAG-Tumbaco genotypes. The assessed variables were defoliation, sprouting, elapsed flowering time, and harvest period. The fruit harvest was shortened by 18.4 days by applying the defoliants and sprout inducer. For the San JosÃ© de Minas genotype, the best response for defoliation (99%) was copper chelate at 1%, compared to the control with 58.9% defoliation at 35 days after its application. In the MAG-Tumbaco genotype, the best defoliation results were also obtained with cooper chelate at 1% (99.7% defoliation), while the control achieved 95.5% for 35 days after its application. In the latter genotype, defoliants significantly outperformed the control in terms of sprouting at 21 and 28 days after application; as a result, harvest was advanced by 22.6 days. These treatments should be tested in other climate zones to establish them as cultural practices to increase off-season fruit production, benefiting farmers and industry.
Modified EC2's Shear Strength Equation for No Coarse Aggregate RC Beams
Authors: Christianto Daniel , Makarim Chaidir Anwar , Tavio Tavio , Pratama Indra Dharma
Published: December 2022

High-strength concrete is one of the various special concretes that have become increasingly popular in recent decades. High-strength concrete offers a higher strength-to-volume ratio than normal-strength concrete. However, the design provision is not explicitly served in most building codes. This study focuses on the shear strength of high-strength concrete and one of many factors that influence the shear strength, i.e., the longitudinal reinforcement ratio. The influence of the longitudinal reinforcement ratio was analyzed and compared with twelve high-strength reinforced concrete beams without coarse aggregate. Concretes with cylinder compressive strengths ranging from 58 to 110 MPa were used. The concrete mixes were made without coarse aggregate, with the maximum aggregate size of #30 sieve. The beam specimens were reinforced with various longitudinal reinforcement ratios and were tested until failure using a four-point bending test setup. The tests showed that the degree of influence of longitudinal reinforcement was in agreement with the Eurocode 2 (EC2) formula, but the formula overestimated the concrete's shear strength. Based on the results, a modification was then proposed to the existing formula to improve its accuracy for high-strength concrete. The modified formula significantly improves shear strength prediction accuracy compared to the existing EC2-2004 and the formulas by other researchers for specimens used in this research. Due to the limited number of specimens used in this research, future research could be done to verify the resulting modified equation and generalize it for a wider range of concrete strength and section shape.
Keep All Objectives Satisfied (KAOS) to Event-B Models Transformation
Authors: Saharudin Syahana Nur'Ain , Said Mar Yah
Published: December 2022

Requirements engineering is an important aspect of the software development methodology because it is the first phase in every software development. The usefulness of formal language in requirements is well-established to ensure consistency. However, the conversion from informal requirements to the formal specification phase is still challenging because it requires advanced skills and much practice. Due to this challenge, we improve the conversion and relationship of these two phases by capturing requirements using KAOS approach and writing the formal specification using Event-B language. KAOS approach allows modeling the requirements through goal hierarchies, whereas Event-B is a formal system-level modeling and analysis method. This work proposes model transformation rules from KAOS model to Event-B model, along with implementing the rules, and evaluates the proposed rules using Mine Pump Controller case study. We used a model-driven approach, specifically model-to-model transformation, to transform KAOS model to Event-B model. We modeled the case study into the KAOS model to obtain the source model for our model transformation and extend the existing KAOS meta-model by adding four new meta-classes to ensure the KAOS model can accommodate all Event-B components. Our proposed rules manage to generate an abstract Event-B model, and a set of proof obligations have been used to verify the correctness of the model. However, the designers must manually perform the transition between the generated outputs to the Event-B platform.

Mole concept is an essential part of chemistry learning and has been the prerequisite to learning other chemistry concepts. The learning source has not yet completely connected the three representations levels. The inability to connect the three levels of representations might affect students' learning outcomes and mental models. This study aims to determine the effect of structured inquiry-based modules on students' mental models of the mole concept. The design of a study is Randomized Control Group Postest Only Design. There were 141 students from two Senior High Schools in Padang recruited as the samples of the study. The instruments are two-tier mental diagnostic tests and semi-structured interviews. The model category of students' mental model on mole concept in experimental group I demonstrates that the level target was 34.29%, Intermediate 3 was 60%, and Intermediate 2 was 5.71%. Control group I shows that the target level was 28,57%, Intermediate 3 was 45.71%, and Intermediate 2 was 25.71%. Meanwhile,experimental group 2 shows that the level target was 22.86%, Intermediate 3 was 71.43%, and Intermediate 2 was 5.71%. Control group II had the following categories, the level target was 14.29%, Intermediate 3 was 62.86%, and Intermediate 2 was 22.86%. The result of the t-test on hypotheses reveals that the mental model of the mole concept in the experimental group was higher than the control group of both schools. Hence, it can be said that the module affects students' mental models of mole concepts in both schools.

For some periods, information technology has developed, but there are some issues with its data security. For this reason, exploring the data hiding method is relevant, which is an appropriate study in the information concealment paradigm. Several factors must be considered in its implementation, such as the capacity of the confidential data and the quality of the generated stego file. Nevertheless, it is difficult to solve those two problems simultaneously in actual application. We often need to choose either one of them, which is more suitable for a specific environment. In this research, those problems are approached by extending the Quad General Difference Expansion Cluster (QGDEC) method combined with fuzzy logic in the image environment. We use the cluster in the QGDEC, which aims to ensure that the pixel difference is not significant so that the quality of the stego can be maintained. The confidential data can be embedded in multiple layers based on several image characteristics, which can be processed using fuzzy logic. The result of the experiment denotes that the proposed method obtains about 20 dB higher than that of the previous ones regarding the Peak Signal to Noise Ratio (PSNR) for the same capacity of the secret. It depicts that the proposed method is more applicable than the previous ones by considering the specific message size and its respective characteristics.

LAPAN-A3 (LA3) data has been utilized for earth observation in monitoring natural resources. While most applications are toward land resources monitoring, recent utilization indicates the possibility of LA3 detecting oil spill events on the sea surface. This research provides information regarding the ability of sensors characteristics of LA3 to detect oil slicks and its initial results by examining multispectral bands combination using Optimum Index Factor (OIF), and Digital Number (DN) extraction is carried out on each LA3 band in water-oil-water since LA3 is not able to change DN to reflectance value. In this study, besides using LA3 data, Sentinel-2 data was also used as comparative data and results in validation. Based on the results of the OIF calculation, the combination of the Blue-Green-NIR (BGN) band has the highest value compared to other combinations. This indicates that the BGN band combination is appropriate for visualizing oil and distinguishing between oil and water. The pattern formed from the visualization results with the combination of the BGN band is silvery in crude oil and greenish in ship waste disposal. The result is also strengthened by DN extraction from slick oil samples that shows a prominent pattern on the Blue and Green bands. Finally, this study can conclude that LA3 has great potential to detect oil spills visually but still requires further research for reflectance analysis by converting the DN value into reflectance.

Dengue hemorrhagic fever (DHF) is a common disease in tropical countries such as Indonesia that is often fatal. Early predictions of DHF case numbers help reduce the risk of community transmission and help related authorities develop prevention plans and strategies. Previous research shows that temperature, rainfall, and humidity indirectly affect DHF spread patterns. Therefore, this research uses and compares three machine learning modelsâ€”restricted Boltzmann machine-backpropagation neural network (RBM-BPNN), artificial neural network-genetic algorithm (ANN-GA), and artificial neural network-particle swarm optimization (ANN-PSO)â€”to predict DHF case numbers in DKI Jakarta, the capital of Indonesia, which is in the DHF red zone. RBM and PSO are used to calculate optimal initial weight and bias before starting the prediction stage with ANN; meanwhile, GA updates weight and bias during the backward pass in ANN. The data includes temperature, rainfall, and humidity, plus previous DHF case data for five districts in DKI Jakarta from Jan. 6, 2009, to Sept. 25, 2017. We used Arima, Autocorrelation, and Pearson correlation for pre-processing data. The DHF case data fluctuates strongly and requires the moving averages method. The data consists of 70% training data and 30% testing data. The results show that each district requires different model architectures for the best predictions. `The best RMSE prediction of DHF cases with RBM-BPNN in Central Jakarta is 3,78%; the best RMSEs using ANN-GA in North and East Jakarta are 5,65% and 5,99%, respectively. The ANN-PSO model had the largest RMSE value in every district, with an average of 8,43%.

Understanding the project environment is essential in managing the works and controlling the risks associated with deep excavations in urban areas. The study was carried out on 33 risks related to the project site (SR) and the company (CR). The projects concerned are located in the Casablanca region. A structured survey questionnaire was sent to 100 project managers, researchers, and construction management experts to attract relevant data, which resulted in a relatively high response rate of 54%. This paper applies the principal component analysis (PCA) method to reduce the original data variables and identify risk factors associated with deep excavations. Spearman rank correlation tests show a good consensus among respondents to corroborate the results further. The PCA results in four principal factors (SR) accounting for 68% of the variance explained. Site geology, geotechnics, and hydrogeology account for 32% of the environmental and social impacts of excavation (17%), natural hazards (10%), and proximity to existing structures (8%). Moreover, four main factors (CR) explain about 72% of all the factors analyzed; non-security of the works (32%), non-quality of project staff (18%), project cost overrun (14%), and non-quality of excavation works (9%). These results are useful for critical thinking in planning excavation projects in urban areas. This study provides the urban development community with valuable information to reassess risk factors and realign project management strategies to ensure the quality and safety of deep excavations.
