The objective of this research was to present a methodological proposal for the identification of areas lacking equipment for early childhood education in the municipality of Porto Alegre / RS, using Geoprocessing tools. The methodology included data from the demographic census and the school census, which were manipulated through Geoprocessing tools for the generation of thematic maps. The mapping was performed on two scales of analysis. On the first scale of analysis, the municipality was analyzed divided into 17 regions, with two regions being selected for more specific analyzes, as they have low rates of attendance to early childhood education. In the second scale of analysis, the two selected regions were mapped with a greater level of detail, using the dasimetric method. In addition, were mapped points with the geographic coordinates of daycare centers and preschools for the generation of recruitment rays, in order to identify the areas with low conditions of access to this equipment. Thus, two priority areas were identified for the installation of daycare centers and two areas for the installation of preschools. Considering that the databases used in this research are national in scope, the use of this methodology makes it possible to compare the different realities of supply and demand for early childhood education among Brazilian municipalities.

Decision-making in urban planning should be based on accurate information on the performance of the spaces produced related to socioeconomic and environmental aspects. However, despite the current pattern observed in the peri-urban areas of most Brazilian cities, the planning system implemented does not establish models for investigating conflicts arising from the production of urban space. To expand the forms of assessment and control of environmental impacts, a theoretical-methodological framework is presented for assessing the performance of the space produced in urban areas of environmental preservation. The indicators of that framework are important measures to identify internal discrepancies to the system, showing its heterogeneity. The present study aimed to assess the performance of the Master Plan for Urban Development of the city of Pelotas, RS, Brazil in the production of space in areas of Environmental Preservation. The investigation considered socio-spatial, socioenvironmental and socio-economic aspects. The proposed analysis uses multivariate statistical analysis to classify the space produced. The study is useful in the production of a framework for monitoring and managing the current and future panorama of development in urban environmental preservation areas.

Authors: Wan Lirong , Jiang Kao , Zeng Qingliang , Gao Kuidong
Published: January 2022

Vibration is an inevitable phenomenon in the coal cutting process and severe vibration leads to efficiency loss for cutting equipment. To understand the impact of vibration on cutting equipment and explore the measures to improve the stability, the dynamic response of cutting equipment is analyzed. The shearer drum, which always undertakes coal cutting task and is the vibration source in working process, is established with finite element method and the relations between cutting performance and vibration characteristics are analyzed. Hydraulic system, vulnerable to external shocks, is also established and the dynamic responses of hydraulic piston under different working stages are analyzed. In the frequency domain analysis on cutting load, results show that a vibration signal with higher amplitude appears, which is consistent with the drum vibration frequency. It demonstrates that drum vibration happens under impact load, especially during height adjustment stages. The research provides the methods for vibration reduction and would be helpful for improvement of shearer reliability

Concentration, Foreign Participation and Bank Performance: An Empirical Study of Asian Emerging Markets
Authors: Liu Ting-Kun
Published: January 2022

There is an abundance of literature on the relationship between market structure and profitability. Market share and concentration are usually analytical tools serving as indicators of market structure. There have been many empirical studies based on the structure–conduct–performance (SCP) theory. However, the correlation between market structure and bank interest spread has rarely been discussed in depth. Therefore, this paper constructs financial industry firm-level panel data of Asian emerging market countries from 2001 to 2015 to further explore the impacts of foreign bank participation, financial market concentration and the level of competition on bank spreads. Apart from the differences in samples, the most significant difference from the previous literature is that this paper considers the best indicators of competitiveness, namely the H value of the Panzar–Rosse (P-R) model to measure the banking market and competitive conditions. This study provides a more complete and detailed analysis by adopting the system GMM approach to perform the estimation and avoid the problem of endogeneity. Regarding the overall sample, the participation of foreign banks has had a positive and significant impact on bank interest spread, suggesting that the participation of foreign banks is a major factor influencing bank interest spread in the general financial markets in Asian emerging market countries, and that more foreign banks in local financial markets can help improve bank performance.

Authors: Marzuki Marziana Madah , Wahid Khalid Abdul
Published: January 2022

The study aimed to examine the effects of the Government Link Companies Transformation (GLCT) Programme in Malaysia on Government Link Investment Companies (GLICs) as the major shareholders of the Government Link Companies (GLCs). A series of semi-structured interviews were undertaken with key individuals from two GLICs in Malaysia. Our findings revealed that the existence of GLICs are still relevant as GLICs believed that their investments in GLCs are to protect the welfare of relevant parties of their institutions. The GLCT programme has not reduced the government’s share in GLICs, but instead it improved the governance and polished new talent management in GLICs. In addition, the study findings revealed that the improvement of GLICs after GLCT is due to effective leadership with good governance and integrity implemented in the GLCT. The findings are crucial to consistently enhance the effectiveness of Government Transformation Programmes (GTP) towards better performance among GLCs in Malaysia.

Evaluation of the Jarless Method for Cyclone Calibration in Occupational Air Sampling
Authors: KIMBROUGH LESHAN J.
Published: January 2022

The jarless cyclone calibration method is an appealing approach because it removes the need for calibration adapters and eliminates potential sources of error that result from poor or inconsistent seals in calibration adapters or calibration jar lids. The aim of this study was to perform a detailed review of the jarless calibration method by (1) examining the rationale behind the initial pressure drop range specified by the method and (2) evaluating the accuracy of the method in contrast to flow rate measurements in a well-controlled, jar protocol. Four types of respirable cyclones and two filter brands with samples from three separate production lots were considered as components of the sampling trains under consideration. Volumetric flow rate and pressure drop were measured under controlled conditions in a cylindrical jar designed for these determinations. The initial challenge pressure range evaluated in this study was modified based on cyclone type. The measured pressure drop fell within the modified range for all configurations considered, indicating the modified ranges were appropriate. The accuracy of the jarless method was then evaluated by comparing measured volumetric flow rates using different calibration methods for various cyclone, filter brand, and filter lot combination. The jarless method provided accurate calibration results utilizing the modified initial pressure drop ranges utilized in this study. Therefore, it is recommended the initial pressure drop range specified by the jarless method be modified to account for differences among cyclone types.

Authors: Rovesht Tohid Jamali , Manafpour Mohammad , Lotfi Mehdi
Published: January 2022

Shock waves have undesirable effects, such as excessive dynamic pressure on spillway walls and the extension of flow beyond spillway conduits. To eliminate these detrimental impacts, designers have attempted to detect the characteristics of these waves. Flow interaction with chute piers generates triple waves in the middle walls and sidewalls of spillway conduits. The present study quantitatively investigated the characteristics of these waves with respect to variations in the bottom inclination angle (θ), wall contraction (φ), and Fr numbers (). The results indicated that with the increment of θ, , (φ, ), and (θ, ), the height () and distance () of the first wave increased, which can be helpful for flow aeration. Furthermore, owing to a boost in θ, , (φ, ), and (θ, ), the height of the second wave was decreased. Therefore, the amount of dynamic pressure on the spillway walls was reduced. Moreover, the distance of decreased with a rise in θ, φ and increased with the increment of and (φ, ). As for , raising φ and (φ, ) elevated the height of this wave and declined its distance. An increase in the height of boosted the flow turbulence and aeration.

Published: January 2022

Planning an event-based monitoring campaign on the regional scale is challenging, e.g. the timing and location of monitoring visits can dramatically impact monitoring efficacy and depends on the optimal environmental conditions required by the measurement parameters and the overarching monitoring goal. Therefore we developed a generic campaign planning approach utilizing interactive visualization methods and implemented this approach into the component-based web tool called Tocap: Tool for Campaign Planning. As a case study, we determine the most suitable time and location for event-driven, ad-hoc monitoring in hydrology using soil moisture measurements as our target variable. Our approach supports: (1) data acquisition from various digital data sources, (2) identification of the most suitable locations for measurements, (3) identification of the most suitable time for measurements at the selected locations, and (4) planning an optimized monitoring route.

Published: January 2022

Heavy metal contamination in the urban river has become the most severe problem in the urban environment, especially the zinc (Zn) compound is harmful to the environment at current levels of exposure. This study aims to assess the impact of urbanization and industrialization on Zn pollution in surface sediment at the Umeda River. Triplicate surface sediment samples were collected at nine sample points. An atomic absorption spectrophotometer was used for analyzing the Zn and Fe concentrations. The surface sediments in the Umeda River contained 48–159 mg/kg of Zn. The results indicated that Zn concentrations were abundant in the ascending order of 600–1,000 μm, 300–600 μm, and smaller than 300 μm. The higher the grain size, the higher the particulate organic carbon which might contribute to the higher Zn and Fe concentrations. In addition, the sediment quality guidelines indicated that the Zn levels in the study area did not constitute a major threat to biota. Normalization with Fe showed that the Zn pollution in surface sediment had been influenced by anthropogenic activities such as industrialization and urbanization.
A new method to determine the scale range of environmental damage caused by water pollution accidents
Authors: Guo Gaimei , Duan Runbin
Published: January 2022

Recently, water pollution accidents have happened frequently and have caused serious environmental damage. The purpose of this study was to propose a new method to determine the scale range of environmental damage in water pollution events. In this study, taking Fen River in Shanxi Province as an example, a computer simulation system was used to simulate the diffusion and migration process of phenol at different concentrations, so as to determine the curve series of the scale range of environmental damage caused by the simulated water pollution event. At the same time, taking the incident of water pollution caused by phenol leakage in Jingle County as an example, the actual scale range of environmental damage was compared with the simulated scale range, so as to determine the error of the scale range of environmental damage. The results showed that the maximum error of the curve series of the scale range of environmental damage was 22.4%, and the minimum error was 7.5%, which indicated that the error of the scale range of environmental damage was small, and proved that this method of quantitatively determining the scale range of environmental damage had certain scientific nature.

Published: January 2022

The characteristic analysis of cyanobacterial organic matters is an important premise of cyanobacterial organic pollution control. This paper investigated the component structure characteristics of algal organic matters (AOM) secreted and released by cyanobacteria in laboratory culture and actual Taihu Lake environment by spectroscopic quantitative and qualitative methods. Results showed that the secretion amount of AOM was mainly 4–6 μg COD/106 cells during the growth period of Microcystis aeruginosa, and the content ratio of extracellular organic matters (EOM) to intracellular organic matters (IOM) gradually increased from 0.83 in adaptation and logarithmic period to 3.33 in stable and decay period. The secretion of IOM showed a decrease trend, which indicated the decrease of its synthesis or the gradual infiltration and loss caused by cell membrane damage. From the component characteristics, the EOM had lower SUVA value and higher proportion of small molecular substances with molecular weight <3 kDa, indicating its more difficult to separate from water than IOM. Compared with the laboratory culture environment, the actual Taihu Lake resulted in more obvious characteristic heterogeneity of cyanobacteria EOM and IOM.

Both black and white sesame seeds are abundant in not only macro or micronutrients but also contain plethora of bioactive components such as lignans and phytosterols contributing to it being a good source of antioxidants. Presence of sesamin, sesaminol, myristic acid and lecithin in sesame seeds attributes to its antiinflammatory, anti-hypertensive, anti-hyperglycemic, anti-hyperlipidemic and anti-cancer properties. Sesame oil is also known for its anti-microbial activity. Sesame is also an important crop mentioned in Ayurveda and is used in shirodhara, a body relaxing technique. Its oil is also used as skin softener and is utilized in the treatment of cracked heels. Seasame oil can also be substituted with regular oil and its seeds are used as garnishes in breads, biscuits and crackers. Til chikki and laddo’s are also prepared in Indian households. Though it is widely used, consumption of even two sesame seeds might trigger allergic reactions in few people. In this review article topics like nutritional composition, therapeutic benefits, uses, products developed and safety and dosage of sesame is discussed.

Published: January 2022

The aim of this research enquiry is to foster a collaboration with Nottingham Castle realising public activities to improve visitors’ engagement. Methods used to explore these enquiries involved Scenarchitecture, a trans-disciplinary methodology developed by Moneta, that uses the process of reading, understanding, and interpreting the Genius Loci as an in-depth exploration and expression of Spatial Practice and community engagement. Recent studies on phenomenology of Place (Relph, 1976; Alexander, 1977; Norberg-Schulz, 1980), and the role of Genius Loci in Placemaking (Brooks, 2001; Golan, 2012), are confirming the importance of considering a multidisciplinary approach to enhance heritage sites using perception and emotions. Heritage sites with their peculiar identity and character, provoke intense spatial experience in those who engage with them, having the quality of Place, i.e., the power to focus human experiences, and actions spatially. The enquiry was about researching and then revealing historical characters that had a role in the NC’s history, and to help audiences engage with them on a perceptual level through storytelling, site-specific performance and CosProps as the medium. The project involved six students of BA (Hons) Theatre Design at Nottingham Trent University as part of the Realised Design curriculum, that selected and designed a CosProp for each character. They devised the performances in collaboration with six students of The Television Workshop in Nottingham. The work was funded in kind by NC (supporting staff and use of spaces and facilities) and by NTU (£1000.00). The final outcome is a promenade performance across different stories and characters located in specific places of the NC Grounds; the audience followed the promenade in small groups to adhere to Covid19 regulations. A questionnaire after the performances evidenced that ‘the performance enhanced the experience of the Nottingham Castle grounds’ (73.3%). The dissemination of the work includes pages on NTU and NC website and a video published on YouTube.

Published: January 2022

With the increase in the number of the global population, that is likely to grow also in the nearest decades, the expansion of cities continues at the expense of forests and farmlands, and in these new areas, a more significant role is granted to the interaction between cities and countryside, revealing diverse interests of stakeholders. It is necessary to preserve, and it is even desirable, to expand the green spaces of the urbanized territories. Vienna, Stockholm, Copenhagen and Riga were selected for the study. The authors looked at the experience of the urban and green area planning through the literature review of city planning documents. Analyses of results show that planning takes place at the city, suburban or regional level and in the case of Riga, its development is similar to the development of other large European cities. The share of the urban forests in the territory of Riga city and its suburbs is comparatively large. In the European cities, which are rich in forests, the territories of the urban forests are often owned by local municipalities, and the development axes are created along highways, separating the diverse green territories. The authors offer a schematic model of the urban forest and urban area development for Riga city, which will ensure the preservation of forest areas and the non-confluence of urban areas.

Authors: Tuyet Phan Nga Thi , Chen Cheng-Hu
Published: January 2022

Despite the popularity and the importance of MOOCs in global education in recent years, they have not become the focus of self-efficacy studies. In addition, most available MOOC research resides in Western economies, not in Asian countries. No studies up to this point have explored the change in engineering student self-efficacy before and after they finish a MOOC or the relationship between engineering students’ self-efficacy and academic performance in a MOOC learning environment. This present study examined if there were any changes in the self-efficacy levels of a group of students before and after they attended a blended MOOC on English Technical Writing skills. It explored the relationship between self-efficacy and academic performance and looked for possible differences in self-efficacy and academic performance with respect to different demographic variables. A Paired-samples t-test helped to measure differences in self-efficacy scores at the beginning and end of the course. Pearson correlation was conducted to examine if self-efficacy predicted students’ course grades at the end of the course. Descriptive analysis, t-test, and ANOVA were used to measure the differences between the mean scores of self-efficacy and academic performance regarding different demographic variables. Results showed that students became more self-efficacious after they attended the blended MOOC. Self-efficacy significantly predicted academic performance. Students who reported higher self-efficacy levels gained better scores. Participants differed significantly in their self-efficacy and academic performance in relation to age group, English proficiency level, and educational level. Suggestions for future research are made based on the results of the study.
“I’ve Decided to Become an English Teacher”: Pre-Service EFL Teachers’ Reasons for Choosing Teaching as a Career
Authors: BAŞÖZ Tutku
Published: January 2022

Purpose: The present study aimed to probe pre-service EFL teachers’ reasons for choosing teaching as a field of study and future career in the under-researched context of Turkey. The variance in their career motivations in terms of grade level was also examined in the study. Besides, the study aimed to explore whether any of the factors influencing their career motivations predict their academic achievement.
Design/Methodology/Approach: The Factors Influencing Teaching Choice Scale (Watt & Richardson, 2006) was administered to 155 pre-service EFL teachers enrolled in the English language teaching (ELT) department of a state university in Turkey. The emergent data were first descriptively analyzed to find out the career motivations of the participants. Multivariate analysis of variance (MANOVA) was also performed to explore whether grade level significantly affects pre-service EFL teachers’ career motivations. Lastly, a standard multiple regression analysis was used to investigate whether any causal relationships exist between the participants’ career motivations and their achievement as represented by their GPA.
Findings: The results of descriptive statistics demonstrated that the participants had moderately high level of career motivations. Grade level did not have any significant impact on their career motivations. The findings of the multiple regression analysis demonstrated that, of the factors affecting teaching choice, only time for family, desire to work with children, intrinsic career values, and desire to make social contribution emerged as the predictors of GPA, explaining 47% of the variance in the pre-service EFL teachers’ academic achievement.
Conclusion: In the process of teacher education, it is vital to acknowledge and incorporate the multiple motives of career choice that EFL student teachers hold. Organizing teacher education programs drawing on multiple motives might contribute significantly to completion of teacher education and teacher retention in future profession.

Published: January 2022

Increasing soybean production can be done by growing the crops in marginal soil, such as saline soil. Therefore, saline-tolerant genotypes are important to support the cultivation. The objective of the experiment was to evaluate the performance of 18 soybean varieties grown under salinity stress. The experiment was done from May to July 2021 at the greenhouse of the Department of Agronomy, Faculty of Agriculture, Bengkulu University, about 10 m above sea level. Soybean seedlings were grown in 10 cm diameter plastic pots fertilized with AB-mix solutions supplemented with 0 or 6 dSm-1 NaCl for 15 days. The growth and stress-tolerant index of the seedlings were measured. The results showed that soybean variety had different growth as responses to salinity. Moreover, salinity stress imposed at 6 dSm-1 NaCl significantly reduced crops growth and promoted leaf senescence. We found that 18 soybeans varieties were classified as salinity tolerant at 6 dSm-1.

The legal protection of computer and information systems, prevention and counteraction to cybercrimes becomes a relevant problem for society and the state. In one or another way, the computer-related crimes, infringement of the interests of users, and intentional distribution of false or harmful information, pose a serious threat to the information system security, as well as interests of the state, rights and freedoms of citizens. The dependence of people and society as a whole on computer and information systems is higher with each year. Generation Y cannot imagine their life without digital technologies. Cybercrime (intellectual crime) implies the unauthorized access to computer systems and databases, infliction of damage, and commission of criminal offense via computer. Such crimes are characterized by being difficult to detect, intellectualism, wide variety, duration and serious threat to the society. The scholars distinguish two types of cybercrimes: in the first instance, computer is viewed as the object of crime, while in the second — the instrument of crime. The first case suggest theft of the computer and its parts, hacker attacks and various types of sabotage, spread of computer viruses, etc.; the second case suggests the distribution of pornography and pirated software, Internet fraud for the purpose of embezzlement, as well as money laundering.
Wiosna Ludów. Wpływ konfliktów politycznych z połowy XIX wieku na późniejsze wydarzenia społeczne
Authors: Toman Aleksandra
Published: January 2022

W moim artykule zwróciłam uwagę na historyczną i współczesną percepcję rewolucyjnych wystąpień w krajach XIX-wiecznej Europy. Akcentowałam aspekt narodowowyzwoleńczy, zjednoczycielski i egalitarny. Pisałam o Francji „trzech chwalebnych dni” w lipcu 1830 za panowania króla Ludwika Filipa Burbona. Przywołałam wojnę o niepodległość Grecji przeciw Imperium Osmańskiemu. Wiele miejsca poświęciłam zrywom antyhabsburskim w Austrii, w Królestwie Węgier i w Królestwie Czech. Później zajęłam się kampanią generała Józefa Garibaldiego i Wiktora Emmanuela II, który koronował się na króla zjednoczonych i suwerennych Włoch. Następnie skupiłam się na zamieszkach w krajach Cesarstwa Niemieckiego, które z trudem przeistaczało się w monarchię konstytucyjną.Przedstawiłam sugestie w sprawie Wiosny Ludów czy raczej jej braku w Wielkiej Brytanii oraz w Imperium Rosyjskim. Nawiązałam przy tym do powstania polskiego przeciw carowi Mikołajowii 29 listopada 1830. Starałam się ocenić temat w sposób racjonalny i rewizjonistyczny, dlatego uwzględniłam zarówno pozytywne, jak i negatywne aspekty powstań. Ostatecznie uznałam, że do pewnego stopnia ukształtowały one współczesną kulturę polityczną.

Patients with trichobezoar present with a history of nausea, pain, vomiting, and occasionally with signs of acute abdomen. We report a case of trichobezoar that presented with gastric perforation and peritonitis which required laparotomy and longitudinal gastrotomy for evacuation of the trichobezoar.
Fuzzy Logic Based Control of a Fuel Cell/Battery/Ultra-capacitor Hybrid Power System via a Multi-Phase Multi-Input Converter
Authors: CAN Aykut , AKAR Furkan
Published: January 2022

Fuel-cell (FC) based electric vehicles (EVs) are promising to reduce the carbon footprint due to the transportation sector. FCs are environmentally friendly systems that generate electricity from hydrogen and oxygen. Unfortunately, FCs solely fail to meet the high power density requirements of EVs. Therefore, this paper presents a FC/battery/ultra-capacitor (UC) hybrid power system (HPS) for electric vehicle applications. In this work, the power conversion is realized employing a single dc-dc converter which is a multi-phase multi-input converter to offer a compact and efficient HPS. After analyzing the converter, a fuzzy-logic-based energy management strategy (EMS) is developed to limit the rate of change of FC and battery power levels and regulate the voltage of UC. Finally, the offered EMS has been evaluated thanks to simulation models of the converter and sources.
The South China Sea Conflict and Security Cooperation in ASEAN Waters
Authors: Wardhana Rifqi Setia
Published: January 2022

The study aims to analyze how ASEAN acts to keep the region from conflicts over the South China Sea. The South China Sea conflict is a conflict that has a major impact on the ASEAN region; it is influenced by the territorial waters owned by several countries in ASEAN according to the United Nations Convention for the Law of the Sea (UNCLOS) in 1982. China’s unilateral claim in 2012 was the beginning of ASEAN’s concerns over the security and stability around the South China Sea and ASEAN waters. This article focuses on ASEAN’s response in response to China’s moves after unilateral claims and the establishment of military fleets around the Spratly and Paracel islands. The ASEAN Regional Forum (ARF) on 2018 is an important response for ASEAN in the face of maritime security threats. Establishment of policy strengthening security cooperation will have a significant impact in the development of stability in the South China Sea region, where the situation in the region worsen with the increasing number of actors involved in the conflict. The findings obtained from this paper aim to explain the analysis of ASEAN schemes to safeguard the territorial waters around the South China Sea.

Background: Heparin-induced thrombocytopenia/thrombosis (HIT/T) is characterized by a fall in platelet count 5-10days after starting heparin therapy and is diagnosed with specific 4-T clinical features and laboratory tests. This complication is relatively common in Cardiothoracic surgery patients. Objective: To evaluate the positive and negative predictive value of various HIT laboratory tests and assess any correlation between HIT, the underlying diagnosis, underlying procedure, and mechanical cardiac devices. Patients and methods: The patient’s medical records were correlated with two laboratories HIT diagnostic tests, the pan-specific screening test with IgG, IgA, and IgM antibodies, followed by HIT specific IgG ELISA. Results: Total n = 80 patients were assessed, 48% (n = 38) were HIT screen pan-specific negative and 50% (n = 40) were HIT pan-specific positive and 2 cases were inconclusive. 17% (n = 14) were both pan-specific and specific HIT IgG ELISA positive. There were 5 atypical cases. One patient had Eosinophilic myocarditis and was HIT ELISA IgG neg. Argatroban was given on clinical grounds with successful recovery. One patient with Sarcoidosis had an aggressive course and received IV Immunoglobulin (IVIG) but succumbed secondary to liver failure. One patient progressed to gut ischemia and had surgical intervention but succumbed. Two patients with mechanical heart valves were on Argatroban but relapsed and responded to IVIG therapy. Conclusion: Our study indicates that 9/16 (> 50%) HIT-positive patients had valve replacement or cardiac devices suggesting that like knee arthroplasty there is a high incidence of HIT in patients with mechanical heart valves and cardiac devices and this warrants further prospective study.
