The exploration of the functions of technology on English learning and teaching in Chinese colleges
Authors: Zhang Chenyang
Published: September 2021

Previous studies have proved the significance of technology in language teaching and learning. However, in Chinese colleges, teachers usually pay little attention to integrating technological products (e.g., mobile applications) in English as a foreign language (EFL) teaching, and thus students tend to show low skills to use technology to enhance their EFL learning. Meanwhile, considering the weakness of EFL education in Chinese universities, this argumentative essay aims to improve Chinese educators’ attention to realise the functions of technology on improving the effectiveness of EFL education. With this focus, this essay will discuss the role of technology through four aspects, namely, language, culture, difference and identity. In this regard, four arguments will be presented; 1. language as ‘a representation system’ could transfer and acquire linguistic knowledge in multiple ways through technology; 2. technology could establish a shared meaning map (culture) for enhancing college students’ English communication competence; 3. technology as a medium could distinguish and group linguistic information; 4. identity could be expressed by digital literacies in an information-shared website for language learning.

Red Jabon (Anthocephalus macrophyllus (Roxb.) Havil) is a forest plant that can replace sengon (Falcataria moluccana) because it has advantages. The demand for red jabon wood is increasing, but the cultivation of red jabon is still constrained by the attack of pathogens that cause leaf disease. The attack of these pathogens can cause damage and death of seedlings so that it can be economically detrimental. The aim of this study was to identify the pathogens that cause disease in red Jabon. The method used is the Postulate Koch method, which starts from sampling red leaves with leaf disease symptoms, isolation, inoculation and analysis of disease incidence, re-isolation, and identification. Based on the identification results found as many as 2 pathogenic fungi that cause leaf spot disease, namely Pestalotia sp. and Rhizoctonia sp. In addition, 6 pathogenic fungi were found that cause blight, namely Lasiodiplodia theobromae, Fusarium sp., Colletrotrichum sp., Marssonina sp., Gloeosporium sp. 1, Gloeosporium sp. 2.

Logging activity is one of the factors which changes the structure of forest stand. The objective of this study was to determine the species composition and development of forest stand structure in the IUPHHK-HA area of PT. Barito Putera, Central Kalimantan, especially on the logged over area (LOA) of year 2002, 2007, 2012, and also on the pre-logged area of year 2014 as a comparison (primary forest). Based on observations which have been made, species Shorea leprosula were dominant with different rates of growth in each observation area. Growth development of the stand on logged over area can be said to be normal, because it is in the process toward a normal forest conditions. Potency of the stand before felling in 2014 was 103 trees/ha for the nucleus trees, and 49 trees/ha with volume of 317.25 m3/ha of mature timber (ready to be harvested). On LOA of year 2012, the number of core trees was 77 trees/ha, and 51 trees/ha for mature timber (ready to harvested) with a volume of 584.84 m3/ha. LOA in 2007 exhibited the nucleus trees as many as 93 trees/ha and 53 trees/ha of mature timber (ready to be harvested) with a volume of 427.95 m3/ha. LOA in 2002 exhibited nucleus trees as many as 75 trees/ha and 59 trees/ha of mature timber (ready to harvested) with a volume of 442.41 m3/ha. The differences of growth development in the observation area were probably caused by illegal logging activities that occur in the forest area, and the damage of residual stand (including nucleus trees) as a result of logging and log transportation activities. Logged over forest conditions can be said to be in balance because there were more than 25 nucleus trees/ha remaining, appropriate to the Selective Cutting and Line Planting (TPTJ) regulations, which indicates that the logged over forest can be utilized in subsequent cutting rotation.Key words: composition, Dipterocarp forest, logged-over area, core tree, stand structure.

Dieback disease by the fungus Botryodiplodia theobromae in Jabon seedlings (Anthocephalus cadamba) inhibits the regeneration of Jabon plant. Synthetic fungicides utilization to several problems such as residue on the environment and pathogen resistance. Chitosan is a potential natural compound used as an alternative to control plant disease.This research aims to examine the effectiveness of chitosan to control B. theobromae as causal agent of dieback on Jabon seedlings and to examine the effect of chitosan to control the viscosity of dieback disease on Jabon seedlings. The results showed that the chitosan solution can decrease the severity of disease in Jabon seedlings. However, it was different with the disease incidence rate parameter. Chitosan solution was not significantly affecting the disease because B. theobromae caused dieback symptoms on Jabon seedlings. The most effective treatment was chitosan solution with a concentration of 0.1% before inoculation with the severity of the disease by 25%. Chitosan solution viscosity was responsible in affecting the percentage of dieback disease in Jabon seeds. The higher the viscosity of chitosan, the higher the percentage of dieback disease attacks. The best viscosity to suppress the development of dieback disease on Jabon seedlings was 8.80 with 7.90% attack.Key words: Anthocephalus cadamba , Botryodiplodia theobromae, chitosan, dieback.

Strength in Rotary Friction Welding of Five Dissimilar Nickel-Based Superalloys
Authors:   American Welding Society, TAYSOM BRANDON SCOTT , SORENSEN CARL D. , NELSON TRACY W.
Published: September 2021

Advanced manufacturing processes improve the cost and quality of goods. Rotary friction welding is a fast, energy-efficient, and reliable joining process for metals, but new applications are hindered by large development costs for each new alloy. Each alloy set has different welding characteristics; therefore, lessons learned from a single alloy are not always broadly applicable. To establish knowledge that is applicable across multiple alloys, a family of different superalloys were welded to discover process trends that were applicable beyond a single alloy set. In this study, weld symmetry did not correlate to weld strength across alloy systems. Some alloys’ strongest welds occurred at maximum symmetry, whereas high asymmetry was associated with different alloys’ maximum strength. High feed rates, high welding forces, low energy, and low temperatures all resulted in high-strength welds across all alloy and geometry combinations. Tensile strengths greater than 95% of base-metal strength were recorded for most alloy systems.

Published: September 2021

Bangladesh is one of the main importer countries of e-waste in the world. Moreover, country also generates e-waste about 2.81 million metric tons per year. However, majority of e-waste is being dumped into the open soil, open land, or open water bodies resulting problem on environment (i.e., pollution) and human population (i.e., health). Therefore, present review summarizes the environmental and health impact due to disposal of e-waste. Poorly management of e-waste during the collection, processing, recycling, and land filling causing environmental impact followed by air pollution, soil pollution, water pollution, and degradation of the beach because hazardous compounds spread to the surrounding or environment. Furthermore, e-waste also creates lots of health problems. Humans can be exposed to e-waste contaminants by the inhalation, dietary intake, dust ingestion, and dermic contact. In north eastern part of Bangladesh, about 36.3% women who lives near recycling sites experienced the death of a baby. Again, about 15% child laborers die, and 83% child laborers are affected by long term health problem because of e-waste mismanagement practice. There are about 120,000 Bhangaries who may be exposed to e-waste contaminants more seriously. The result of the study would provide us important insight into the growing concern of e-waste and would help policy maker for designing policy measure to recycle e-waste in a hazard free manner.

Published: September 2021

The financial performance of a bank can be measured through ROA. Bank Indonesia as a supervisory and supervisory institution prioritizes greater profitability, namely the Return on Asset (ROA) of a bank, so banks need to know what factors can affect the ROA of a bank. This study was conducted to analyze the effect of Non Performing Loans (NPL) and Loan to Deposit Ratio (LDR) on Return on Assets (ROA) with Net Interest Margin (NIM) as a mediating variable. The sample of this research consists of Bank Mandiri, Bank BNI, Bank BRI, and Bank BTN for the period 2015-2019. The research methods used include descriptive statistical analysis, outer model analysis, and inner model analysis. The results of this study indicate that NPL does not affect NIM, while LDR has a significant effect on NIM. Furthermore, NPL has a significant effect on ROA, while LDR does not affect ROA. This study also proves that NIM has a significant effect on ROA, but NIM does not mediate the effect of NPL on ROA, and NIM can mediate the effect of LDR on ROA.

In this paper, the authors present a methodological approach for designing assistance systems conducive to learning. The theoretical framework is based on the activity system and the concept of expansive learning. From this, the authors develop the learning activity system. The application and further development of this theoretical framework is presented on the basis of an industrial application scenario of mechatronic reprocessing in the automotive industry. It includes a systematic approach to technology selection and design that serves as a practical action guide for companies designing assistance systems. In addition, dimensions conducive to learning are developed and linked to the activity system approach. This integrated model provides requirements for the design of an assistance system conducive to learning. The paper also describes concrete requirements and measures of a participatory design and implementation process.

Monitoring learners’ mental states via a passive Brain-Computer Interface (BCI) allows to continuously estimate current abilities, available cognitive resources, and motivation. It bears the great potential to adapt educational contents, learning speed, and format to the learner’s needs via an intelligent tutoring system. We present a neurophysiological-based approach to continuously monitor learners’ current affective-emotional and cognitive states by measuring and decoding brain activity via a passive BCI. In two studies (N = 8 and N = 7), we investigate whether we can a) predict learners’ affective and cognitive states during a learning or training session, b) provide continuous feedback of recognized states to the learner and, thereby, c) increase performance and intrinsic motivation. Oscillatory power measures in the alpha (8 – 12 Hz) and theta (4 – 7 Hz) frequency band served as features for the prediction and visualization. Our results reveal that machine learning algorithms can distinguish different states of cognitive workload and affect. The approach contributes to the development of closed-loop neuro-adaptive tutoring systems which allow to monitor learners’ states, provide feedback, and adapt their parameters for an optimal learner-training fit and effective and positive learning experience.

The research project "COVID 19 LL Lessons Learned", funded by the German Federal Ministry of Education and Research (BMBF), aims to identify successful solutions and measures that emerged in three different German regions through a systematic analysis during the pandemic. The regions under consideration are Bavaria (TU Munich), North Rhine-Westphalia (RWTH Aachen) and Saxony (TU Dresden). The aim of the project is to identify the problems that companies and organisations are facing and what they have learned from the change process so far. In this way, it is to be determined whether innovative and digital forms of work that have emerged as a result of the pandemic can provide positive impulses that can prove their worth in the working world in the medium and long term. One of the issues under consideration is the change in competence requirements due to the pandemic-related change in work organisation. The following human-technology-organisation process model was used for the project work.

Digitalization and the increasing technical possibilities of networking machines and products as well as the use of large amount of data in the hole production process offer companies the opportunity to establish new, so-called hybrid business models. This enables them to provide customers data-driven, smart services in addition to their physical products, create more value and strengthen their competitiveness. The hybridization of value creation is accompanied by numerous changes and new competence requirements in companies, which need to be shaped socio-technically. In the AnGeWaNt project, such hybrid business models were developed and implemented in three companies. The article describes the approach to analyzing and shaping changes and competence requirements that arise in companies as a result of digitalization and hybridization.

F. M. Dostoevsky’s Traditions in T. Mann’s Short Story “The Hungry”
Authors: Melnikova Lyubov Alexandrovna
Published: September 2021

The paper aims to reveal specificity of artistic interpretation of the “little man” theme in T. Mann’s short story “The Hungry” in the context of F. M. Dostoevsky’s literary influence. Relying on a comparative historical analysis, the researcher identifies similarity of the writers’ aesthetic attitudes. Both the authors analyze internal experience of people regarded as “insulted and humiliated”. To solve this artistic task, the Russian writer uses the personages’ confessional monologues, whereas the German novelist uses the “outside view” technique representing an outsider’s view on the problem of a “little man’s” suffering. Scientific originality of the study lies in the fact that the researcher for the first time provides a comparative analysis of psychologism techniques used in F. M. Dostoevsky’s novel “Poor Folk” and T. Mann’s short story “The Hungry”. As a result, it is shown that tackling the “little man” problem, both the authors emphasize the necessity of Christian love for one’s neighbor, consider it impermissible to humiliate a “little man’s” dignity because of his poverty and low social status.

The research was conducted at the Scanner Engineering Department of PT Epson Batam. The topic is written about budget management for repair and maintenance (die & mold) costs with the aim of knowing how to minimize the variance between budgeted costs and their realization. Data collection methods used in this study were interviews, observation, and documentation, and descriptive and quantitative methods were used for data analysis. The existing budgeting system in the Scanner Engineering Department has been carried out correctly and effectively met the objectives, but overall during the 2018 fiscal year there were budget inefficiencies. Based on observations, it is known that from the budget made there are still differences (favorable variance and unfavorable variance). Where the difference arises due to unexpected costs for damaged equipment, the difference between the scheduled repair time (service) and the reality, as well as delays in sending invoices or debit notes.
