Hybrid Gs-Ga Algorithm for Parallel Machine Scheduling Problem with Different Transport Vehicles
Authors: Zhang Hongxiang
Published: February 2022

This paper studies the scheduling problem of the same kind of parallel machines with different transportation vehicle capacity. The scheduling problem model is composed of a single warehouse and multiple manufacturers located in different geographical locations. Each manufacturer has the same batch processor, and several vehicles assemble the jobs in the warehouse in batches, transport them to different manufacturers and return them. The manufacturer of vehicle transportation depends on the destination of the jobs when the code is generated. At the manufacturer’s place, because the capacity of the vehicle may exceed the maximum capacity of the batch processor, the job will be re batch for processing after it arrives. Through modeling, a 2n dimensional code is designed, and the gravitational search algorithm is introduced. The mutation and crossover process of genetic algorithm are added. A hybrid genetic algorithm based on gravitational search is proposed. The algorithm is used to optimize the sum of manufacturing time span and transportation cost. The effectiveness of the algorithm is verified by different scale simulation experiments.

Published: February 2022

Under the background of digitization, the basic algorithm of minimal surface provides novel and rich creative themes for architectural design. However, due to the high complexity and extreme thinness, how to convert the mathematical model to the mechanical model has become the biggest challenge in the application of large-size minimal surface. On the basis of analysing the relation between force and form, this paper explores and verifies the concept and method of transforming mathematical model into mechanical model by combining qualitative analysis and quantitative calculation. Combined with a work named “Yunjian Linglong” and the related experiments, it provides theoretical clues for the technical route of highly complex heteromorphic hyperboloid, and empirical reference value for the cooperation between shape design and structural design under the digital background.

Background and Objectives: In the care and treatment of patients in need of dialysis, spiritual experiences as a method of problem-solving in crises and problems can facilitate adaptation to dialysis. This study investigated the mediating role of spiritual experiences with ego strength on the adaptation to dialysis. Methods: The statistical population included all patients in need of dialysis referred to the Educational-Research Center of Abu Ali Sina Hospital in Shiraz City, Iran, in 2019. Out of them, 120 patients were selected by a convenience sampling method. The study data were collected through the Daily Spiritual Experiences Scale (DSES), ego strength, and adaptation to disease. Then, the obtained data were analyzed based on structural equations in Amos v. 21 software. Results: The findings showed that ego strength is significant with spiritual experiences and adaptation to dialysis. But the relationship between spiritual experiences and adaptation to dialysis is not significant. Also, the direct and indirect effects of the variables showed that ego strength as a predictor variable and spiritual experiences as a mediating variable could predict adaptation to dialysis (P<0.01). But the ego strength through spiritual experiences cannot predict adaptation to dialysis. Conclusion: According to the research findings, ego strength can predict disease adaptation in dialysis patients, but daily spiritual experiences cannot lead to disease adaptation in dialysis patients.

O presente artigo é resultado de uma análise de desenhos livres de indivíduos dentro das fases de desenvolvimento narradas por Piaget (1994; 1999), considerando não somente seus estudos sob a perspectiva dos estádios da criança, mas também como funcionaria a evolução de um sujeito através de desenhos e analisados pelo prisma psicológico, com base principal em Georges-Henri Luquet (1969). O problema norteador da pesquisa: é possível detectar diferenças no desenvolvimento psíquico de crianças e apontar fatores comportamentais e emocionais através de desenhos? Assim, o objetivo geral concentra-se em identificar e avaliar as fases de desenvolvimento da criança por meio de desenhos. A metodologia da pesquisa incluiu a revisão bibliográfica, com uma abordagem em quatro crianças com idade entre 2 a 15 anos, de ambos os gêneros, e sem classe social determinante na cidade de São Paulo. Além disso, a premissa de hipótese foi de que as diferenças de fases de desenvolvimento poderiam ser de fácil identificação a partir do conhecimento das teorizações de Piaget, Luquet, Lowenfeld, Brittain, e Florence de Meredieu. Ademais, seria possível que materiais gráficos pudessem influenciar na transferência emocional aos desenhos, e colaborar na leitura avaliativa. Como resultados e conclusões, percebeu-se que é cabível identificar as diferentes fases de desenvolvimento da criança através de desenhos, e que até os materiais utilizados colaboram no reconhecimento das estruturas psicológicas dos indivíduos. Além disso, reforçou-se a importância dessa atividade lúdica como um dos métodos usados pela Psicologia para compreender melhor a personalidade e as possíveis angústias de uma pessoa pelo grafismo, independentemente de sua idade.
Preparing prehydrolyzed kraft dissolving pulp via phosphotungstic acid prehydrolysis from grape branches
Authors: TAO LI , HUA MAYING , JUN KE ZHANG
Published: February 2022

Dissolving pulp was successfully prepared via phosphotungstic acid (PTA) prehydrolysis kraft (PHK) cooking followed by an elemental chlorine-free (ECF) bleaching process from grape branches. The effects of prehydrolysis temperature, reaction time, and PTA concentration that potentially affect the quality of dissolving pulp product on chemical components of pulp were studied via an orthogonal experiment. The structure of lignin was activated during the PTA prehydrolysis phase, and lignin was easily removed during the following cooking process. Thus, relatively mild conditions (140°C, 100 min) can be used in the cooking process. During the prehydrolysis phase, temperature exhibited the most significant influence on the cellulose purity of the obtained pulp fiber, followed by reaction time and PTA concentration. The optimized prehydrolysis conditions were as follows: prehydrolysis temperature, 145°C; reaction time, 75 min; and PTA concentration, 1 wt%. Whether the excessively high prehydrolysis temperature or prolonging the reaction time did not favor the retention of long chain cellulose, the delignification selectivity for the cooking process could not be further improved by excessive PTA loading. Under these prehydrolysis conditions, 94.1% and 29.0% for α-cellulose content and total yield could be achieved after the given cooking and bleaching conditions, respectively. Moreover, the chemical structure and crystal form of cellulose were scarcely changed after PTA prehydrolysis, which could be confirmed by results from Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD). PTA prehydrolysis could be considered as an alternative method for preparing PHK dissolving pulp under relatively mild cooking conditions.
Application of ATR-IR measurements to predict the deinking efficiency of UV-cured inks

Published: February 2022

In recent years, ultraviolet (UV)-curable ink has been developed and widely used in various printing applications. However, using UV-printed products (UV prints) in recovered paper recycling causes end-product dirt specks and quality issues.

A new method was developed that can distinguish UV prints from other prints by means of attenuated total reflectance infrared (ATR-IR) spectroscopy. Application of this method could allow more efficient use of UV prints as raw materials for paper recycling.

First, a mill trial was performed using UV prints alone as raw materials in a deinked pulp (DIP) process. Second, test prints were made with four types of UV inks: a conventional UV ink and three different highly-sensitive UV inks. Each print sample had four levels of four-color ink coverage patterns (100%, 75%, 50%, and 25%). Next, drinkability of all prints was evaluated by laboratory experiments. Finally, each print was measured using the ATR-IR method,
and the relationship between the IR spectra and deinkability was investigated.

Mill trial results showed that UV prints caused more than 20 times as many dirt specks as those printed with conventional oil-based ink. There were variations in recycling performance among UV prints taken from bales used for the mill trial. Lab tests clearly revealed that not all UV-printed products lead to dirt specks.

In order to clarify the factors that affected deinkability of UV prints, the print samples were investigated by lab
experiments. Key findings from lab experiments include:

• The number of dirt specks larger than 250 μm in diameter increased as the ink coverage increased.
• Higher ink coverage area showed stronger intensity of ATR-IR spectral bands associated with inks. These results
indicate that deinkability of UV prints could be predicted by analysis of ATR-IR spectra.
• Finally, the method was applied for assessment of recovered paper from commercial printing presses. It was confirmed that this method made it possible to distinguish easily deinkable UV prints from other UV prints.

Based on these findings, we concluded that the ATR-IR method is applicable for inspection of incoming recovered
paper.

Las instituciones modelan, constriñen e inciden en nuestra vida social, hacen posible que la conducta sea estable, recurrente, repetitiva y pautada en muchos ámbitos de nuestra vida tanto privada como pública: instituciones de familia y parentesco, educativas, económicas, políticas, culturales y de estratificación. Ahora bien, hablar de diseño institucional es hablar de un cambio social intencionado, el cual se encuentra impugnado a partir de distintos modelos de transformación social: accidente, evolución e intención. Desde finales del siglo pasado, Robert E. Goodin promovió el estudio académico e interdisciplinario acerca del diseño institucional, sus aportaciones han sido fundacionales para esta disciplina en nuestra era. Es por ello que el objetivo de este libro es reflexionar sobre las instituciones y sus alcances en el contexto iberoamericano; sobre posibles nuevos enfoques en el diseño institucional para apuntalar y fortalecer nuestras democracias; sobre los desafíos actuales a los que se enfrenta el diseño institucional y también reparar en dos ámbitos de diseño que suelen estar eclipsados en la academia: el diseño de instituciones científicas y culturales, y el diseño urbano.

Social and labor aspects of livestock development of livestock in agricultural enterprises
Authors: Lanchenko Y
Published: February 2022

The subject of scientific research is the scientific and practical principles of development of the labor market and the market of livestock products in Ukraine. The purpose of the article is to substantiate the areas of formal employment and increase livestock production in agricultural enterprises. The data of the State Statistics Service of Ukraine, normative-legal acts of Ukraine and the following methods of scientific research are used: abstract-logical; system approach; monographic; statistical and economic; balance.
Based on the analysis of meat and milk consumption by the population of Ukraine, it is proved that there is a violation of the balanced diet of the population, which is one of the main tasks of state social policy. Its structure has a large shortage of meat products (35 % of norm); dairy products (46 % of the norm), etc. In the studied period of 2014-2019, the production of livestock products, in particular beef and veal, significantly decreased.
The scenario-empirical calculation of the increase in formal employment in agriculture due to the increase in domestic production of livestock products to ensure a rational food balance of the country and the formation of export supplies showed the following. It is possible to involve more than 900 thousand workers in agricultural enterprises. These indicators correspond to the need to increase the number of jobs in rural areas (about 500 thousand unemployed and more than 600 thousand self-employed people in households alone).
It is proved that to ensure a socially oriented direction of livestock development in agricultural enterprises it is necessary to increase the efficiency of livestock production to ensure short-term employment and wages, stability of employment, development of rural areas and communities.
Based on the analysis of economic indicators, livestock and cows in different types of agricultural producers, the content of employment in animal husbandry, it was possible to substantiate social and labor imperatives and the relevant organizational and economic principles of livestock development in large, medium and small agribusiness. The development of the latter is especially important due to the transformation of efficient rural households into farms and small agribusiness enterprises.

Institutional traps of land reform in the context of land ownership changes
Authors: Zakharchenko V.
Published: February 2022

The article considers topical issues of institutional support of land reform in Ukraine in the context of changes in ownership of land.
The purpose of the research is to disclose the essence and significance of land ownership institutions to avoid institutional traps associated with the change of forms of land ownership at the final stage of land reform in Ukraine.
It is shown that agricultural land is the largest natural wealth of Ukraine, so it should be used as rationally as possible. It is proved that the land reform was to be carried out as successfully as possible in the transition to market relations. The need to transform old and create new institutions or "rules of the game" in land relations, in particular, property institutions on agricultural land, is justified. It is noted that among these institutions there are also those that produce negative results; V.M. Polterovich defines them as institutional traps. It is found that institutional traps were caused by the uncritical application of the theory of neoliberalism on total deregulation of economic, including land, relations during the implementation of land reform in Ukraine.
Institutional traps that appeared as a result of the transformation of popular land ownership into communal and private land, in particular, such as: violation of constitutional norms on universal land ownership; the appearance of dissonant norms of land ownership; overestimation of the land appropriation transaction and the background of underestimation of the transaction for its effective use; legalization of illegally obtained and purchased land plots; transfer of land from state property to communal to simplify their privatization schemes; theft of subsoil under the form of acquisition of land plots; increase of land fraud from registration of land owners and tenants; activation of land raiding; underestimation of land value due to infringement of ownership; understatement of the role of the state in protecting the ownership of land.
Ways of avoidance and smoothing of institutional traps associated with transactions to change forms of ownership of land are proposed. The emphasis is on the transactions of effective use of agricultural land, and not the transaction of ownership of them.
Key words: land reform, market turnover of agricultural land, institute, institutional trap, form of ownership of land (state, communal, private).
Efficiency of state support for milk production in Ukraine
Authors: Semsal A. , Shupyk S.
Published: February 2022

The article is devoted to the evaluation of the effectiveness of state support for milk production in Ukraine.
It is proved that in order to overcome the negative trends in the industry and increase the investment attractiveness of dairy farming in the strategic and future perspective, it is necessary to increase the effectiveness of state regulation, increase state support and improve subsidy mechanisms.
We believe that the positive impact on ensuring the efficiency of milk production in agricultural enterprises has also been achieved through the introduction of such a tool as subsidies to finance the construction of new farms. We believe that it is necessary to introduce cheaper costs for the modernization of production facilities in agricultural enterprises, construction of innovative processing facilities.
It is proved that the low efficiency of state regulation instruments of dairy farming and large amounts of investment, the industry does not attract new producers. In addition, the country has not created appropriate conditions for the transition of OSG from milk production to small businesses and increasing the production capacity of farms, which also does not lead to the emergence of new players in the raw milk market. At the same time, the experts took into account the risk of entering new foreign players.
It is established that the main factors of the external environment that affect the effective development of dairy farming are: state support of the industry and innovation, improving the investment climate. Internal factors of effective development of the industry are related to; availability and optimal structure of fixed and current assets; rational selection and placement of staff; rational use of forage lands; improving the breed composition of the herd; development of material and technical base; increasing the rate of renewal of fixed assets; increasing the level of mechanization and automation of technological processes; introduction of innovative technologies of cattle keeping and feeding; compliance with scientific requirements for herd reproduction; integrated diversification; development of the system of planning and forecasting, rationing and cost control; an effective system of employee motivation, a flexible management system and appropriate social security for employees.

Published: February 2022

The article is devoted to the problem of formation of the system of institutional support of investment activity of agricultural enterprises.
A significant increase in the investment attractiveness of micro-agricultural enterprises will occur with the formation of family farms based on them, where former migrant workers will be the leaders. They will invest the earned money in the development of their own economy, and in entrepreneurial activity they will use the gained work experience in agriculture of the European Union. We believe that in the near future in Ukraine it is possible to oppose the "Brazilian" and "European" models of agriculture.
At the same time, the level of concentration of assets and agricultural lands does not always create the preconditions for their effective use. This opinion is confirmed by the low importance of investment efficiency of large agricultural enterprises. This situation may be due to volatility in prices for basic agricultural products, reduced state support for agriculture, and increased integration processes in the world market, which will facilitate access to the domestic market of foreign agricultural producers, which are characterized by higher productivity.
The directions of support of investment activity in agriculture by the leading countries of the world on the basis of tools use of direct and indirect influence which main task was the expansion of access of commodity producers to long-term credits and other financial services are allocated. Among the areas of indirect influence that are relevant for domestic conditions, we should highlight: scientific and production services for agricultural producers through the system of agricultural consulting at the expense of budget funds; financing and stimulation of scientific activity; development of public-private partnership to stimulate the implementation of innovative projects; use of public procurement as an instrument of investment activity.

The article is devoted to the economic principles of formation of innovative development of breeding pig breeding in Ukraine.
It is established that the breeding herd of breeding plants is carried out on the principle of self-repair, breeding pigs by the method of "closed" population, breeding breeders - mainly repair pigs of own reproduction, obtained and raised directly on the farm. Repair boars to replenish the herd are purchased from other farms, and when the ancestral herd is organized, they are raised directly in the association. In commodity herds of pig farms and breeding complexes it is desirable to carry out repair boars and pigs from breeding farms, and if necessary with a clear primary zootechnical record breeding repair pigs to replace lost queens can be carried out directly in the enterprise.
Given the limited import of breeding pigs due to the spread of ASF in the world, the main task of breeding farms is the cultivation and sale of high quality young stock. However, in recent years, repair boars and pigs obtained and raised in domestic breeding enterprises are often not in demand in the market.
Based on the results of the analysis, it can be concluded that the established domestic breeding base does not require unsystematic mass imports except for a small number of high-value breeding young or sperm odes of prominent breeding boars to refresh the blood of some herds under the methodical control provided by the state scientific and technical programs.
The current situation in industrial pig breeding primarily requires solving the problems of automation of management of breeding and breeding work with the use of modern computer technology. The solution of this problem is especially important if the production of commercial pork uses hybridization systems, which requires a clear organization of the breeding herd when working with large populations of animals.
At the same time, stabilization and further effective development of breeding enterprises cannot be ensured without modernization of instruments of state support of breeding farms, preservation and efficient use of the best domestic genetic resources and world gene pool of pig breeds, improvement of production activities and strengthening of integration with large industrial complexes.
Key words: breeding pig breeding, agricultural enterprise, state support, commercial pig breeding, innovation.

Natural rubber is one of the commodities that plays an important role as a foreign exchange earner. This study aims to determine how the competitiveness of natural rubber in Indonesia and Thailand as the main producers in the world market. The data used in this study is the volume of exports and imports of natural rubber in Indonesia and Thailand for 15 years in the 2004-2018 period. This research uses Revealed Comparative Advantage (RCA) analysis to analyze comparative advantage and Trade Specialization Index (ISP) to analyze competitive advantage. The RCA analysis results in world markets, the United States market and the Chinese market show a number of more than 1 which means that natural rubber in Indonesia and Thailand have strong competitiveness or comparative advantage. However, in the world market and the United States market the value of the Indonesian natural rubber RCA index is higher than the Thai RCA index value so that the competitiveness of Indonesia's natural rubber is stronger than Thailand, while in the Chinese market the value of the Thai RCA index is the opposite. Indonesia and Thailand ISP Index values show positive results, indicate that these two countries have a tendency to be an exporter of natural rubber commodity in the world market, the American market, and the Chinese market.

Renewable energy and other methods of minimizing emissions into the atmosphere should be a priority for each country. This approach should be extended to Antarctica scientific stations.The study main objective was to obtain the necessary estimates of the wind energy potential of the Galindez Island territory to estimate the feasibility of installing wind turbines on the territory of the Akademik Vernadsky station. The study of the wind properties over the territory was based on the British Antarctic Survey archive of meteorological parameter average annual values (1950–2020), 3-h wind speed and direction data, registered by the Akademik Vernadsky station (2011–2020), and average daily data from meteorological observations (2014–2018). The Hellman parameter was calculated from satellite data. A number of statistical methods were used to analyze the vertical wind profile, particularly the method of minimizing the arithmetic mean relative modeling error. To assess the amount of generation, the wind speed data at the height of the anemometer sensor were recalculated to the height of the wind turbine axis. Using the wind power characteristics provided by the developers, average annual wind power generation was avaluated. For calculations of wind energy potential, we chose the technique developed by the Department of Wind Power of the Institute of Renewable Energy of the National Academy of Sciences of Ukraine. The analysis of the wind conditions showed a high average daily wind speed (3.9 m/s) and the prevailing wind direction (north – northeast 24%). The results support the hypothesis about the expediency of installing wind turbines on the territory of the Akademik Vernadsky station. The wind turbine was selected for further wind power calculations based on the other countries experience of using wind turbines in Antarctica and considering the specifics of installation and operation in conditions of high wind speeds, low temperatures and high relative humidity. Based on information on fuel consumption at the Akademik Vernadsky station, it was estimated that the installation of 10 wind turbines SD6 would meet 28.4% of the station's yearly electricity needs.
