Optimization in Handling Tasks in Monorail Transportation System at Busan Port
Authors: Nguyễn Duy Anh , Lê Long Ngọc Bảo , KIM Hwan-seong
Published: April 2021

This paper presents an optimal solution for handling tasks at Busan Container Port in South Korea. Currently, there is a monorail transportation system being constructed and supposed to be ready in use in 2045. It is a project in association with Korean Government that aims to increase the utility rate at Busan Port – one of the biggest container port in the world. At the moment, the main transport mean at Busan Port is truck – whose speed is about 40-50 km/h, however this traditional method leads to a low productivity and traffic congestions on the road. An innovation is to build a monorail system that could operates at high speed (about 80-90 km/h) along the entire port to transfer standardized containers. This new transportation system is expected to strongly reduce the delay in transporting as well as increase the overall efficiency for the system. In new system, there are transport vehicles called shuttles that would move on the rail in only one direction, and to turn back in the opposite way, there are some special stations called change stations that would direct the shuttles into the other lanes – which is similar to the lane driver systems on the railway. Containers at each inner terminal in Busan Port will be grabbed onto the shuttles by special equipments called loaders – a kind of giant automated manipulator that would load or unload whenever a shuttle requires. To optimize the operation, we introduce a heuristic algorithm called Greedy Algorithm for scheduling tasks and assigning tasks – two major actions in a cycle work that significantly affects to the system’s performance. First, the containers at each loader position will be sorted in a proper sequence, and then the sorted schedule will be assigned to proper shuttles in order to lower the total working time and delay time as much as possible. The overall performance is simulated by MATLAB software, including the result charts showing the main criteria points, in order to highlight the advantage of new transportation system.

Published: April 2021

The study was conducted to establish a formulation for development of jackfruit seed protein (JSP) enriched cake. After extracting from jackfruit seeds, the JSP flour was added as substitutions of wheat flour at a level of 0%, 3%, 6%, 8% and 10% to prepare protein enriched cakes. The cakes were then analyzed to find out the acceptable formulation by assessing their physicochemical properties and sensory attributes. The cakes prepared with 6% JSP isolate secured the maximum sensory scores in terms of color, flavor, taste, texture, and revealed the highest overall acceptability (7.58 ± 1.01) suggesting ‘like very much’. The proximate analysis of 6% JSP enriched cake showed 15.26%, 11.59%, 25.91%, 1.06%, 2.03%, and 44.15% moisture, crude protein, crude fat, ash, crude fiber, and carbohydrate respectively. An increase in JSP level in cake formulation decreased the volume, weight, specific volume and water activity while the baking loss showed a reverse trend. The JSP enriched cake also exhibited a reduction in vitamin A content and peroxide value, and an increased calorific value. Microbiological analysis of the JSP enriched cake showed an acceptable quality by 10 days of storage (25 ± 2 °C). Therefore, maximum 6% JSP flour could be added as a substitute of wheat flour to formulate a protein enriched cake having good preferences and overall acceptability.

Published: April 2021

The dietary chitosan has been largely used in the supplemental diets of terrestrial animals to improve growth and development. However, there is little information on the roles of dietary chitosan in growth and development of aquatic animals like fishes. Thus, this study aimed at determining the effects of dietary chitosan on growth performances and survival of Barbonymus gonionotus fry. A total of 600 B. gonionotus fry (2.12±0.02 g) were considered for this study. This experiment consisted of four treatments (0, 1, 2 and 3 g Kg-1 formulated feeds) and each treatment had three replications with a stocking density of 50 fry/tank. The dietary chitosan was supplied as 8% of body weight of each fry twice daily for 60 days. Fish fry treated with the dietary chitosan exhibited significant (P < 0.05) improvement in growth (body weight gain, % body weight gain, specific growth rate, and feed conversion ratio) and survival of B. gonionotus in comparison with untreated control. The water quality parameters, such as temperature, pH and dissolved oxygen showed no significant variations, and maintained suitable range throughout the study period for fish growth. Among the treatments, application of 1 g chitosan kg-1 feed showed the highest positive effects on growth and survival of B. gonionotus fry, indicating their potentials for practical application in promoting sustainable aquaculture.

Acesso legal ao conhecimento tradicional associado à biodiversidade no Brasil: Novas perspectivas nacionais
Authors: Souza André Luiz Gomes de , Silva Gabriel Francisco da
Published: April 2021

Desde a década de 1980 tem sido verificado acentuado crescimento do número de aplicações tecnológicas de recursos genéticos da biodiversidade baseadas em Conhecimentos Tradicionais Associados (CTA) na busca por soluções aos problemas enfrentados pela humanidade. Decorrentemente, desde o início da década de 1990 o CTA vem sendo objeto de discussão acerca do seu uso legal. Assim, diferentes diretrizes internacionais e instrumentos jurídicos nacionais têm surgido no sentido de estabelecer condições apropriadas ao acesso e exploração econômica legais e à repartição justa dos benefícios advindos. O estabelecimento de tais condições tornou-se relevante para o delineamento de estratégias de desenvolvimento de países megadiversos e as discussões perpassam pela importância da preservação da biodiversidade, exploração sustentável, impactos culturais e apropriações indevidas. Neste contexto, o objetivo desta pesquisa foi analisar indicadores oficiais de acesso legal ao CTA a fim de explicitar as expectativas nacionais acerca do das efetividades das políticas públicas relacionadas ao tema. O presente estudo se caracteriza por ser uma pesquisa exploratória, documental, quantitativa, histórico e longitudinal. Analisaram-se documentos e dados oficiais divulgados pelo órgão responsável pela regulamentação e deliberação do acesso legal ao CTA no Brasil durante o período de 2002 a 2020. Os resultados demonstram relevante crescimento do número de registros de atividades científicas e tecnológicas com acesso ao CTA regularizadas no Brasil, o que foi impulsionado pela implementação do SisGen. Porém, em contrapartida, a transparência de informações se encontra prejudicada em virtude de indisponibilização de informações que eram divulgadas pelo CGEN durante vigência da MP 2.186/2001.

Authors: Costa Juliana dos Santos , Andrade Junior Luiz Mauricio Lopes de
Published: April 2021

A crescente demanda por eletricidade vem estimulando estudos e ações não somente para o aumento da capacidade de geração de usinas, mas também o uso racional dessa importante forma de energia. Com isso, é notório o crescimento no número de publicações relacionadas ao tema, gerando assim um número demasiado de trabalhos, o que torna a filtragem e análise complexa. Nesse contexto, a revisão bibliográfica é uma importante ferramenta para verificação quantitativa e qualitativa dos estudos publicados nos diversos periódicos.  Diante do exposto, o presente artigo tem como objetivo realizar uma análise bibliométrica da produção científica brasileira sobre a eficiência energética aplicada ao consumo de eletricidade. A base de dados Scopus foi utilizada para a busca dos artigos relacionados ao tema. Foram encontrados um total de 66 trabalhos no período de 2004 a 2020, no entanto, após uma leitura dinâmica verificou-se que apenas 37 desses discorrem efetivamente sobre a eficiência energética atrelada ao consumo de eletricidade. Desses, 83,8% correspondem a trabalhos de estudo de caso, 10,8% as políticas públicas e 5,4% foram estudos de revisão bibliográfica.  A análise permitiu constatar que grande parte dos artigos de estudo de caso foram aplicados ao setor industrial (45,2%), especialmente aos sistemas motrizes. Além disso, observou-se que mesmo o setor residencial sendo um dos principais consumidores de energia, há um número de publicações pouco expressivo, indicando assim uma lacuna a ser preenchida.

Published: April 2021

The role and presence of technology today is very much needed, especially for companies engaged in the service sector. Computerized systems and integrated with other systems will greatly help support the company's wheels and be able to compete with other companies. PT Asta Pilar Gemilang Jakarta is currently still running a manual system in recruiting its employees, so the process from initial recruitment to employee selection takes a long time, and information on the availability of existing job vacancies is only through word of mouth (MOM). The best solution to the existing problems is by designing a web-based employee recruitment information system. Applicants can immediately send and fill out their profiles to the system provided, so that companies will be able to see applicants' data in real time and can immediately select and provide information to applicants. This system is built with the Waterfall system development method, and is designed responsively through bootstrap technology, for system devices using UML with the PHP programming language and MySQL database to accommodate data. With this system is expected to provide convenience, effectiveness and efficiency for companies in providing a decision and comfort for job seekers.

Tunable Negative Poisson’s Ratio in Van der Waals Superlattice

Published: April 2021

Negative Poisson’s ratio (NPR) materials are functional and mechanical metamaterials that shrink (expand) longitudinally after being compressed (stretched) laterally. By using first-principles calculations, we found that Poisson’s ratio can be tuned from near zero to negative by different stacking modes in van der Waals (vdW) graphene/hexagonal boron nitride (G/

h

-BN) superlattice. We attribute the NPR effect to the interaction of

p

z

orbitals between the interfacial layers. Furthermore, a parameter calculated by analyzing the electronic band structure, namely, distance-dependent hopping integral, is used to describe the intensity of this interaction. We believe that this mechanism is not only applicable to G/

h

-BN superlattice but can also explain and predict the NPR effect in other vdW layered superlattices. Therefore, the NPR phenomenon, which was relatively rare in 3D and 2D materials, can be realized in the vdW superlattices by different stacking orders. The combinations of tunable NPRs with the excellent electrical/optical properties of 2D vdW superlattices will pave a novel avenue to a wide range of multifunctional applications.

Stereometry of compressed conoids and physical adequacy of q8 element bases
Authors: Khomchenko Anatoliy , Lytvynenko Olena , Dudchenko Oleh , Astionenko Igor
Published: April 2021

The paper considers new models of bases of serendipity finite elements (FE) Q8. The standard element Q8 has been used in the finite element method (FEM) for more than 50 years despite the physical inadequacy of the spectrum of equivalent nodal loads.In recent years, the library of serendipity finite elements has been significantly replen-ished with non-standard (alternative) models. The reasons for the inadequacy of the spectrum were identified and "recipes" were proposed to eliminate this shortcoming of standard serendipity models. New approaches to modeling bases with the help of hierarchical forms force to abandon conoids - linear surfaces that are associated with intermediate nodes of standard elements. According to the authors, these Catalan surfaces (1843) are insufficiently studied and deserve the attention of modern researchers. Therefore, research is being conducted today, and it is not necessary to give up conoids. The paper shows how by compressing the surface of the conoid it is possible to obtain a mathematically sound and physically adequate spectrum of nodal loads. It is interesting that such capabilities are embedded in trigonometric functions, the popularity of which in the FEM is growing steadily.The purpose of the research is to constructively prove the existence of mathematically substantiated and (most importantly) physically adequate models of serendipity elements Q8 with the help of trigonometric bases.Trigonometric models of the finite element Q8 once again confirmed that serendipity elements are an inexhaustible source of important and interesting information. It should be noted that today it is not necessary to give up conoids for the sake of physical adequacy of the model. Conoids are also of "historical" importance to FEM. The first bases of serendipity FEs were constructed from conoids (1968).Taylor's elegant method (1972) is also based on conoids. New results show that trigo-nometric bases are able to preserve conoids and ensure the physical adequacy of the models.

Atmospheric air monitoring is a systematic, long-term assessment of the level of certain types of pollutants by measuring their amount in the open air. Atmospheric air monitoring is an integral part of an effective air quality management system and is carried out through environmental monitoring networks, which should support timely provision of public information about air pollution, support compliance with ambient air quality standards and development of emission strategies, support for air pollution research.The work is devoted to existing air monitoring technologies: ground (sensors, diffusion tubes, etc.) and remote resources (satellites, aircraft, etc.). In addition, standards of air quality assessment (European and American) are described. As an example, we consider the European Air Quality Index (EAQI) and the Air Quality Index according to EPF standards: indicators by which these indices are calculated, the ranking of air status depending on the value of the index are described.AQI (Air Quality Index) is used as an indicator of the impact of air on the human condition. The European Air Quality Index allows users to better understand air quality where they live, work or travel. By displaying information for Europe, users can gain an understanding of air quality in individual countries, regions and cities. The index is based on the values of the concentration of the five main pollutants, including particles less than 10μm (PM10), particles less than 2.5μm (PM2.5), ozone (O3); nitrogen dioxide (NO2); sulfur dioxide (SO2). To conclude, ground stations give a more accurate picture of the state of the air at a point, while satellite image data with a certain error (due to cloud cover, etc.) can cover a larger area and solve the problem of coverage of stations in the area. There is no single standard for calculation. Today, the European Air Quality Index (EAQI) is used in Ukraine and Europe.
