Authors: Singgalen Yerik Afrianto , Purnomo Hindriyanto Dwi , Sembiring Irwan
Published: March 2022

The use of information technology in the management of Micro, Small, and Medium Enterprises (MSMEs) is not limited to business performance and productivity but also aspects of data security and transactions using various mobile, website, and desktop-based applications. This article offers an idea to explore cybersecurity awareness and risk management of MSME actors who adopt information technology. The research method used is qualitative with a case study approach in the Coffeeshop X business and the Y Souvenir business in Salatiga City, Central Java, Indonesia. The data collection technique used in-depth interviews, observation, and document studies. These findings indicate that Cybersecurity Awareness, especially information security awareness, can be reviewed based on knowledge, attitudes, and behavior. Risk management can be review based on supply risk, operational risk, and customer risk. Cybersecurity Awareness and Risk Management in MSMEs is holistic and cannot be generalized, so it needs to be discussed contextually based on case studies. In the context of Coffeeshop X and Souvenir Y, the level of Cybersecurity Awareness (knowledge, attitude, behavior) is not always linear. In addition, risk management is more dominant in the customer risk dimension, compared to supply risk and operational risk.

Authors: Syahra Sensa Gudya Sauma , Sari Yunita , Suyanto Yohanes
Published: March 2022

The development of automated essay scoring (AES) in the neural network (NN) approach has eliminated feature engineering. However, feature engineering is still needed, moreover, data with labels in the form of rubric scores, which are complementary to AES holistic scores, are still rarely found. In general, data without labels/scores is found more. However, unsupervised AES research has not progressed with the more common use of publicly labeled data. Based on the case studies adopted in the research, automatic text summarization (ATS) was used as a feature engineering model of AES and readability index as the definition of rubric values for data without labels.This research focuses on developing AES by implementing ATS results on SOM and HDBSCAN. The data used in this research are 403 documents of TEACH ON E-learning essays. Data is represented in the form of a combination of word vectors and a readability index. Based on the tests and measurements carried out, it was concluded that AES with ATS implementation had no good potential for the assessment of TEACH ON essays in increasing the silhouette score. The model produces the best silhouette score of 0.727286113 with original essay data.

There are many agencies that have databases but are left without proper management. For example, in tourist attractions in Kota & Kab. Tegal, along with the rapid development of tourism technology, the tourism industry requires the tourism industry to apply information technology to provide convenience for tourists to find out tourist areas according to the cost, and the distance of the tourist attractions entered. The provision of tourism information helps tourists to consider and make decisions to travel. Tahani Fuzzy Logic was chosen because the concept of Fuzzy logic is easy to understand, flexible, and because the Tahani logic method is a form of decision support where the main tool is functional with the main input criteria determined by the user/tourist. This system was implemented using web programming and MySQL database, where the variables to be considered are Type of Tour, Number of Facilities, Price of Tour Tickets, Number of Tourist Visitors, Travel Distance from City Center. The results of this study are a decision support system for tourism selection in Tegal using Fuzzy Tahani which can recommend tourist attractions in Tegal which are determined by tourists depending on tourist criteria based on the firestrength of the selected variables

Bulk cooking oil is a food ingredient that is widely used by the public. The seller uses used bulk cooking oil to be mixed with new bulk cooking oil or even mixes it with harmful ingredients. Lab tests are needed to determine the quality of cooking oil, but the lab test requires a long time and can also damage the content of the cooking oil so it cannot be reused. The focus of this research is the creation of a system that can detect the purity of cooking oil by utilizing the wave velocity measurement method without damaging the shape and nature of the cooking oil.Wave velocity measurements are carried out by propagating ultrasonic waves on objects with a wave frequency of 40 kHz. The value of the duration of the wave propagation time at a distance of 19.4 cm is sampled and used for the calculation of wave velocity. The results of these wave velocity calculations are used to determine the purity level of cooking oil. Then the results of the purity level obtained were analyzed with an approach to the value of fluid viscosity. The results of the wave velocity values show that the waves propagate faster if the purity level of cooking oil is higher and produces a positive correlation with R2=0.9784. The results of the analysis conducted with the approach to fluid viscosity also showed a positive correlation with R2= 0.9999. The average wave velocity in pure bulk cooking oil is 1174.90 m/s.

Published: March 2022

Abstract: In this work, we employ a key access control management scheme which effortlessly transitions any organization-like security policy to state of the art cloud level security. Offering a very flexible, secure, and hierarchical key access mechanism for institutions that deal with mission-critical data. The scheme also minimizes concerns about moving critical data to the public cloud and ensures only the users with sufficient permission from equal or higher privileged members can access the key by the use of topological ordering of a directed graph which includes self-loop. The main overheads such as public and private storage needs are restricted to a level that is tolerable, and the derivation of key is computationally fast and efficient. From a security perspective, the proposed scheme would be resistant to collaboration attacks and would provide key in distinguishability security. Since the key isn’t stored anywhere so, the problem of a data breach is eliminated.

Assessment of M30 Grade Self Compaction Concrete by Partial Replacement of Bagasse Ash in Place of Cement and Glass Powder in Place of Fine Aggregate
Authors: Veerendra Polisetti , Gangabhavani Ch.
Published: March 2022

Abstract: Self-compacting concrete (SCC), a recent innovation in concrete technology, has numerous advantages over conventional concrete. Self-compacting concrete, as the name indicates, is a type of concrete that does not require external or internal compaction, because it becomes leveled and consolidated under its self weight. SCC can spread and fill all corners of the formwork, purely by means of its self- weight, thus eliminating the need of vibration or any type of consolidating effort. This report demonstrates the possibilities of using Bagasse ash and Glass powder as partial replacement of cement and fine aggregate in concrete. This experimental investigation was performed to evaluate the strength properties of concrete, in which the cement is partially replaced by Bagasse ash and fine aggregate was partial replaced with Glass powder. Cement was replaced by weight with five percentages (0%, 5%, 10%, 15%, 20%) and fine aggregate was replaced with only one percentage (20%) of Glass powder by weight. Fresh properties of self-compacting concrete were studied. Compression test, splitting tensile strength and flexural strength test were carried out to evaluate the strength properties of concrete at the age of 7, 14, and 28 days. Keywords: Bagasse ash, Glass powder, Self-compacting concrete, splitting tensile strength, Compressive strength, flexural strength.

Abstract: Polavaram Project is being executed on River Godavari near Ramayyapeta village of Polavaram Mandal, West Godavari District, Andhra Pradesh. This multipurpose major project envisages construction of 2454m long Earth-cum-Rock fill (ECRF) dam across river Godavari near Polavaram with a maximum height of 50.32m. The proposed ECRF dam will be founded on a bed of sand. The depth of sand bed over the underlying rock strata varies from 30m to 90m at different location. To restrict the flow of seepage water through the sand bed, a plastic concrete diaphragm wall/Cut-Off wall is proposed with its top end embedded in the clay core of the ECRF Dam and the bottom end embedded into underlying hard rock. The wall was constructed of plastic concrete using panel construction method. Plastic concrete was selected to provide a seepage Cut-Off wall that has sufficient strength to withstand both static and seismic stresses beneath the new embankment, and yet is flexible enough to undergo seismic deformations, without cracking, with the surrounding soils. This paper illustrates the construction of the plastic concrete Cut-Off wall for the Polavaram ECRF dam, including the field and laboratory testing performed to confirm design wall stiffness, strength, and hydraulic conductivity requirements. The trial laboratory and field testing programs to determine plastic concrete mix design, and the QA/QC testing conducted during construction are presented.

Published: March 2022

Utilization of efficient technologies, renovation of buildings and
construction of new passive buildings, replacement of coal, natural gas, and
nuclear power plants with ?clean? technologies such as photovoltaics and
wind, transition to 4-D in industry, and electrification are parts of the
objectives set out in the Green Deal of the EU. The Green Deal foresees a
transformation to a ?green? economy while maintaining economic growth, as
well as creating new ?green? jobs. To meet these goals, each country needs
to develop its own strategic documents that will guide the transition,
taking into account its own specific conditions, the cur-rent state of the
energy sector as well as geographical location. This paper aims to present a
vision for the energy transition of a developing country, a member of the
Energy Community, and a country that expects to join the EU. The vision of
the development of the energy system of North Macedonia foresees a
transformation from a system based on fossil fuels, where the share of RES
in the gross final energy consumption is about 18%, to a 43% share of RES in
2040, while maintaining import dependence at the current level and
guaranteeing the security of energy supply. For exploring the way and the
pace at which such a vision can be achieved it is necessary to develop
different models and simulations, including different technologies on the
generation and consumption side. Such alternatives, packaged in different
scenarios, allow policymakers to assess the effects of taking certain
actions and the direction in which such decisions will lead.
Using the Same Provider for Financial Statement Audit and Assurance of Extended External Reports: Choices and Consequences
Authors: Lu Meiting , Simnett Roger , Zhou Shan
Published: March 2022

Independent assurance of extended external reports (EER) is one of the most significant trends in today’s global assurance profession. When companies decide to purchase third-party assurance on EER, they need to decide whether to engage their financial statement auditor or a different assurance provider. We examine factors that impact this decision, and the consequences of this decision on financial statement audit quality and cost. We find that independence concerns are associated with companies choosing different EER assurance providers from their incumbent financial statement auditors, while providers’ expertise in EER assurance and the recent trend of integrating nonfinancial information into the annual report promote the use of the same provider. We further find some evidence that companies with the same provider attesting to both financial statements and EER benefit from having higher financial statement audit quality without paying significantly different audit fees.
Effects of compressive stress combined with mechanical vibration on osteoclastogenesis in RAW 264.7 cells
Authors: Changkhaokham Boontida , Suamphan Sumit , Pavasant Prasit , Jitpukdeebodintra Suwanna , Leethanakul Chidchanok
Published: March 2022

Objectives

To investigate the effects of compressive force and/or mechanical vibration on NFATc1, DCSTAMP, and CTSK (cathepsin K) gene expression and the number of tartrate-resistant acid phosphatase (TRAP)–positive multinucleated cells in RAW 264.7 cells, a murine osteoclastic-like cell line.

Materials and Methods

RAW 264.7 cells were subjected to mechanical vibration, compressive force, or compressive force combined with vibration. Cell viability and the numbers of TRAP-positive multinucleated cells were evaluated. NFATc1, DCSTAMP, and CTSK gene expressions were analyzed using real-time quantitative reverse transcription polymerase chain reaction.

Results

Compressive force combined with mechanical vibration significantly increased the numbers of TRAP-positive multinucleated cells but did not significantly affect cell viability. In addition, compressive force combined with mechanical vibration significantly increased NFATc1, DCSTAMP, and CTSK mRNA expression compared with compressive force or vibration alone.

Conclusions

Compressive force combined with mechanical vibration induces osteoclastogenesis and upregulates NFATc1, DCSTAMP, and CTSK gene expression in RAW 264.7 cells. These results provide more insight into the mechanisms by which vibratory force accelerates orthodontic tooth movement.

This study aimed to evaluate the relationship between higher team-based continuity of care, defined as consultations provided by the same physician team, and CVD risks in patients with diabetes from public primary care clinics.

This was a retrospective cohort study in Hong Kong of 312,068 patients with type 2 diabetes and without any history of CVD at baseline (defined as the earliest attendance at a doctor’s consultation in a public-sector clinic between 2008 and 2018). Team-based continuity of care was measured using the usual provider continuity index (UPCI), calculated by the proportion of consultations provided by the most visited physician team in the 2 years before baseline. Patients were divided into quartiles based on their UPCI, and the characteristics of the quartiles were balanced using propensity score fine stratification weights. Multivariable Cox regression was applied to assess the effect of team-based continuity of care on CVD incidence. Patient demographics, smoking status, physiological measurements, number of attendances, comorbidities, and medications were adjusted for in the propensity weightings and regression analyses.

RESULTS

After an average follow-up of 6.5 years, the total number of new CVD events was 52,428. Compared with patients in the 1st quartile, patients in the 2nd, 3rd, and 4th quartiles of the UCPI had a CVD hazard ratio (95% CI) of 0.95 (0.92–0.97), 0.92 (0.89–0.94), and 0.87 (0.84–0.89), respectively, indicating that higher continuity of care was associated with lower CVD risks. The subtypes of CVD, including coronary heart disease and stroke, also showed a similar pattern. Subgroup analyses suggested that patients <65 years of age had greater benefits from higher team-based continuity of care.

CONCLUSIONS

Team-based continuity of care was associated with lower CVD risk among individuals with type 2 diabetes, especially those who were younger. This suggests a potential flexible alternative implementation of continuity of care in public clinics.
Interaction of low-fluence femtosecond laser pulses with a composite layer containing Ge nanoclusters: A novel type of nanofoam formation

In the present work, the low-fluence nonablating femtosecond laser irradiation (λ = 800 nm) of the GeO2 layer with Ge nanoclusters protected by SiO2 layers is studied by different types of microscopy (optical microscopy, atomic force microscopy, and scanning and transmittance electron microscopy) and Raman spectroscopy. After the laser modification, the multilayer thickness increased by 6%–29% depending on the laser fluence. It was found that the laser fluence of ∼40 mJ/cm2 was the optimal value for observing the swelling effect and was below the ablation threshold. Irradiation at this fluence led the Ge nanoclusters to decrease in size from 5–8 to ∼2 nm and crystallize, while the GeO2 matrix expanded due to the formation of GeO bubbles. The fabrication mechanism of the novel type of nanofoam consisting of a glassy matrix, cavities filled with gas, and semiconductor nanocrystals with reduced size dispersion is discussed. Presumably, this effect is associated with the selective absorption of IR (800 nm) laser radiation by Ge nanoclusters.
Alignment but not Alliance: Nordic Operational Military Cooperation
Authors: Saxi Håkon Lunde
Published: March 2022

Since the start of the Ukrainian crisis in 2014, the Nordic states have sought to advance their defence cooperation “beyond peacetime” to also encompass operational military cooperation in crisis and armed conflict. Relations between the two Nordic non-NATO members, Sweden and Finland, have formed a vanguard, encompassing bilateral operational planning beyond peacetime. While no formal security policy guarantees have been exchanged, Sweden and Finland have created strong expectations that they will lend each other support in a crisis. In short, while no formal alliance treaty exists, the two states have nevertheless become closely aligned. In 2020, Sweden and Finland joined NATO member Norway in signalling their intention to strengthen their trilateral defence relationship. The following year, NATO members Norway and Denmark signed a similar agreement with Sweden. The goal of these documents was to coordinate their national operational plans – their “war plans” – and perhaps develop some common operational plans. In this article, it is argued that these agreements fall short of a formal military alliance, but that they represent an alignment policy between the Nordic states.
The Strategic Role of Land Power on NATO’s Northern Flank
Authors: Wegge Njord
Published: March 2022

The debate about how to defend NATO’s northern flank is closely connected to geographic particularities, the demanding Arctic climate, as well as to ever-evolving technological developments. This research article aims at investigating the role land power plays in this region, with a special focus on northern Norway. Through investigating how structure and composition of land forces matter at the political-strategic level, as well as the role played by allied land forces in Northern Norway, this article seeks to better connect the ongoing debate about the structure of land forces in northern Norway to the political-strategic level. The article seeks to answer the research question by using historical sources and official military documents, as well as qualitative interviews.
Vetenskap, profession och politik: Om förändring av det pedagogiska kunskapsområdet i Sverige
Authors: Lindblad Sverker
Published: March 2022

The purpose of this essay is to analyse changes in the field of education sciences and research in Sweden. In focus are matters of research relevancing in relation to intellectual organization and scientific ethos. Three periods are identified: Academic Establishment 1890-1940; Scientific Expansion 1940-1990; and Academic Fragmentation 1990-onwards). These periods are related to different ways of relevancing educational sciences and to research positions. External pressures are increasing, in turn stressing demands for the research community to analyse and discuss these pressures and their constraints and opportunities in relation to educational research and premises for knowledge organisation and scientific ethos.

Published: March 2022

Introduction. The article deals with the problems of deterioration of water quality in rivers in the Rostov region, their shallowing and drying out. The degradation of reservoirs is associated with various aspects of economic and industrial anthropogenic activities. The degree of influence depends on the intensity of the negative impact, and can be reduced if environmental measures are implemented.

Problem Statement. The objective of this study is to monitor the water quality of the Glubokaya River in the Rostov region on different sections of the river and to assess the degree of anthropogenic impact.

Theoretical Part. Water quality studies were carried out in three channels of the Glubokaya River on the territory of the cities of Millerovo and Kamensk-Shakhtinsk, as well as near them. The content of ammonia, phosphorus was determined by spectrophotometric analysis methods and petroleum products by IR photometric analysis method. The results of the study of water quality in the reservoir are compared with the normative values for three years with a certain periodicity.

Conclusions. The results of the studies on changes in the chemical composition of water at various sites in dynamics, taking into account the degree of anthropogenic load, are analyzed.
