Development of an International System of Units (SI)-traceable transmission curve reference material to improve the quantitation and comparability of proton-transfer-reaction mass-spectrometry measurements
Authors: Worton David R. , Moreno Sergi , O'Daly Kieran , Holzinger Rupert 
Published: March 2023

Abstract. Since its inception more than 2 decades ago, proton-transfer-reaction mass spectrometry (PTR-MS) has established itself as a powerful technique for the measurements of a wide range of volatile
organic compounds (VOCs) with high time resolution and low detection limits
and without the need for any sample pre-treatment. As this technology has
matured and its application become more widespread, there is a growing need for accurate and traceable calibration to ensure measurement comparability.
As a result of the large number of VOCs detectable with PTR-MS, it is impractical to have a calibration standard or standards that cover all
observable compounds. However, recent work has demonstrated that
quantitative measurements of uncalibrated compounds are possible provided
that the transmission curve is accurately constrained. To enable this, a
novel traceable multi-component gas reference material containing 20
compounds spanning a mass range of 32 to 671 has been developed. The
development and compositional evolution of this reference material are described along with an evaluation of its accuracy and stability. This work
demonstrates that for the majority of components the accuracy is < 5 % (most < 3 %; < 10 % for
hexamethylcyclotrisiloxane (D3-siloxane) and 1,2,4-trichlorobenzene – 1,2,4-TCB) with stabilities of > 2 years (> 1 year for acetonitrile, methanol and perfluorotributylamine – PFTBA).

Abstract. In temperate climates, agricultural ditches are generally bounded by seasonal vegetation, which affects the hydrodynamics and mixing processes within the channel and acts as a buffer strip to reduce a load of pollutants coming from the surrounding cultivated fields. However, even if the control of such vegetation represents a key strategy to support sediment and nutrient management, the studies that investigated the effect of different vegetation maintenance scenarios or vegetation coverage on the flow and mixing dynamics at the reach scale are very limited. To overcome these limitations and provide additional insights into the involved processes, tracer tests were conducted in an agricultural ditch roughly 500 m long close to Warsaw in Poland, focusing on two different vegetation scenarios: highly vegetated and fully cut. Under the highly vegetated scenario, sub-reaches differing in surficial vegetation coverage are analysed separately to better understand the influence of the vegetation conditions on the flow and mixing parameters. Special attention has been paid to the longitudinal dispersion coefficient in complex natural conditions and its dependency on vegetation coverage (V). The vegetation maintenance decreased the travel and residence times of the solute by 3–5 times, moderately increasing the peak concentrations. We found that the dispersion coefficient decreased approximately linearly with the increase of vegetation coverage at V>68 %. Further research is needed at lower vegetation coverage values and different spatial plant distributions. The obtained longitudinal dispersion coefficient values complement dispersion value datasets previously published in the literature, which are barely available for small natural streams. The new process understanding supports the design of future investigations with more environmentally sound vegetation maintenance scenarios.

Published: March 2023

The presence of social media in our daily life gives both its positive and negative impact to communication manners. This impact also occurs in schools’ environment or even in campus. This paper aims to analyze students’ politeness in communicating through the social media. The study was conducted by providing a survey to 147 students (ages between 19-24 years). The results of the study prove that communication through social media give an impact on students to be more eager to communicate with anyone. However, their communication politeness has decreased, as the survey shows that the ethics of communicating through social media are nor good or polite. Therefore, it can be concluded that the social media has influenced the communication politeness between students and students and between students and lecturers.

FILLING THE LEGAL GAP IN THE BANKING AREA IN VIETNAM BEFORE INDUSTRY 4.0 PRESSURE
Authors: Giang Thu Pham Thi 
Published: March 2023

Since 2016, with the appearance of products of industry 4.0 such as block chain, and products of the block chain associated with banking business area, has created many legal issues that need to be resolved.
Block chain eliminates the third parties/intermediaries in transactions. Therefore, how should the role of financial intermediaries be redefined for the present and the future? What legal risks can happen to Vietnamese investors in the market? There is no clear explanation/statement to answer those questions.
What is the legal definition of crypto currency? What role does it play in financial transactions such as investment? Can we use crypto currency as a payment method? These issues have not been resolved in Vietnam either in theory or by noting in a legal document.
As industry 4.0 is based on a big data system, the current managements, administrations, and identifications that credit organizations are implementing have become obsolete and need an overhaul. Current Vietnamese law has not been able to solve this issue.
The above loopholes need to be reviewed and identified a solution. Also, it is necessary to study and understand other countries’ law adjustments that may be applied and considered to adjust Vietnamese legal system. This article is intended to solve these problems as below.

Identification of signatures is the process of identifying and defining a person’s signature. Identification of signatures including biometics that use natural human behavior. Identification of signatures can be used in security areas such as money withdrawal permits, check validation, credit card transactions and more. During this signature identification is done manually. Difficulty in this way, if the signature to be identified is large, the examiner will experience fatigue. To simplify it needs to be developed to create a computerized signature identification system. In this research, the development of this signature identification is done using the method of zoning and Support Vector Machine (SVM) classification. Based on the tests that have been done, normal test data test resulted in recognition accuracy of 95.31%. In testing the test data with disturbance obtained accuracy of 20.31%. While the testing of artificial signatures generated an accuracy of 70%. In addition to the registered signature image pattern, there are also signature images that are not registered in the database. The accuracy obtained in this test is 100%.

Track and field as a tool for social inclusion in Brazil
Authors: Dieder Janaina Andretta , Sanfelice Gustavo Roese 
Published: March 2023

This study aims to analyze track and field as a tool for social inclusion. It has a qualitative methodological approach. The data collection instruments were interviews/narratives/biographies conducted with 20 Brazilian Olympic track and field medalists. Based on the athletes' reports, track and field is evidently a great tool for social inclusion because most athletes came from vulnerable social conditions, low income families, which are socially excluded in many aspects. Therefore, they found in track and field an opportunity for upward mobility, which can be maintained to help their families after starting in the sport. Other forms of social inclusion by the sport were also noticed, such as higher education scholarships, knowing new places, peoples, and cultures, as well as support for their families.
"Lady Oscar" e "Il Tulipano Nero": caratteri linguistici, affinità e differenze in due cartoni degli anni '80
Authors: Guerra Davide 
Published: March 2023

“Grande festa alla corte di Francia...” è un celeberrimo incipit in Italia conosciuto ovunque e da generazioni diverse, ma che il cartone cui si riferisce, l’anime giapponese Lady Oscar, avesse un “gemello” è un fatto ignoto, o passato in sordina, ai più. Era stata prodotta, infatti, anche la serie animata Il Tulipano Nero - La Stella della Senna, andata in onda due anni dopo il primo (1982 e 1984), la quale trattava lo stesso periodo storico con (quasi) gli stessi personaggi. Alla luce di tali affinità, l'articolo propone un'analisi comparata che mette in risalto le principali affinità e differenze linguistiche, indagando i tratti sintattici, morfologici, pragmatici e lessicali delle due sceneggiature. Dallo studio condotto è stato possibile individuare come il diverso punto di vista dei protagonisti (nobili in Lady Oscar, popolani ne Il Tulipano Nero), attraverso cui vengono lette le vicende, abbia portato ad una marcata differenziazione stilistica nella traduzione della sceneggiatura, che si è pienamente armonizzata coi suoi personaggi, creando un linguaggio piuttosto misurato ed ossequioso da una parte (con anche un notevole rispetto delle norme grammaticali), ed insolente e spensierato dall’altra.

Back pain is a condition or disease where the situation is very serious. On average, people with DALY (Disability Adjusted Life Years) have a higher number of HIV, traffic accidents, tuberculosis, lung cancer, chronic obstructive pulmonary disease, and premature birth problems. Every year, 15-45% of people worldwide are affected by LBP. This study aims to determine the correlation between sitting and working positions and the effect of an individual characteristic on low back pain in Bank Kb workers, including age, years of service, body mass index, and mobility patterns. This study used a cross-sectional survey design and quantitative analytical methods. Total sampling is the sampling method employed, and there were 62 responses. The majority of respondents (78.1%) were over the age of 35, had been at their current job for less than ten years (68.6%), had a body mass index below 25 (60.6%), exercised less than three times per week, sat for more than four hours (90.0%), and had unacceptable work postures (>2), according to the results. As a result, there is a considerable link between body mass index and the amount of time spent sitting. Stretching after work, maintaining a healthy lifestyle, and getting adequate sleep are important.
