<![CDATA[This study aims to identify the effect of infill on mechanical behaviour, especially the yield stress and modulus young of polylactide materials with different unit cell structures such as gyroid, diamond, square, and re-entrant but same porosity with value of 60%. Using Computational aided design (CAD) software and analyzed using the finite element method. The results show that the square structure has the highest strength in terms of mechanical behaviour such as yield stress with a value of 27 MPa, while the gyroid is 25.5 MPa, diamond is 25.3 MPa, re-entrant is 23.3 MPa and young modulus square is 2233MPa gyroid is 2199 MPa, diamond is 2195 MPa re- entrant 2182 MPa. In this study, it was also found that the thickness struth of the unit cell and modulus young had a very strong linear correlation with R2 = 0.96 which explains that the higher the thickness value, the higher the modulus young value. The results of this study also show that although lattice structures, especially square ones, have the highest value, TPMS structures, such as gyroids and diamonds, have more stable performance because these structures have an even stress distribution, thereby reducing the risk of failure of the structure. besides that, the researchers concluded that this TPMS can be used as a solution to improve structural performance.]]>

<![CDATA[Many teachings and learning are still applying hybrid learning and several university classes are still conducted online after of the Covid-19 outbreak, and one of the ways was online video conferences to accommodate the need for face-to-face learning. However, distant learning resulted in the loss of metalanguage features that usually support classroom interaction. This research aimed to determine the Translanguaging applicability and benefits for teaching and learning since the metalanguage features were absent from the class interaction. The method used was descriptive, and the approach applied was qualitative. It was found that Translanguaging practice for the online video conference benefits both lecturers and students. It benefits teaching and learning by creating a good learning atmosphere and provides the same experience between online and offline teaching and learning processes. For the lecturers, Translanguaging helped them to simplify difficult materials explanation and bridge the communication with the students. In addition, it also benefits the students, such as handling technical issues, providing chances to share new vocabulary, and dodging misunderstanding of the lesson explanation. To conclude, implementing translanguaging in online video conference classes benefits and fits the students' learning needs.]]>

<![CDATA[In this financial oriented business world, the risk and risk measuring activities such as identifying the issues, analysing and modifying of ambiguity in the credit creation and investment behavioural decision making. (Kishk et. al. 2008) Basically, the risk management process comes when a stakeholder of a corporation or the fund allocator decides on the basis of analysis and attempts to evaluate the probable losses in any investment. To avoid this kind of risk or technically termed as the moral hazard problem, the investor has to take certain necessary action for gaining better profitability or minimize the risk of loss. The risk management strategies are termed as behavior of the financial risk (Moles, 2016). The present paper aims to study the various behavioral decision-making process of the manager or the investor of the corporation towards the profitability. It also aims to emphasizes the impact of this strategic behavior of the firm or corporation’s decision on the successful growth and establishment. The study is significant with respect to evaluate the cause and effect through the strategies implemented by the investors. It also attempted to reveal the project success story by implementing the risk averse practices. The project victory criteria are a measurable or quantifiable term of expected outcome of the running project which must be accepted by the stakeholder. Financial risk measurement is always being an implicit proportion of the management in the firm or industry. The present study adopts the descriptive research method and uses the secondary data sources published in the company’s websites and annual statements. The collected data have been analyzed by an appropriate statistical and econometrical tool to evolve the relationship between the behavioural aspects of risk management strategies and its influence on the project success of the firm. The risk management of credit on commercial bank is most essential for the benefit and stop suffering from the losses on the project. Prevention and controlling the risk of loans and advances is a tough and very challenging target for the business project. It is statistically evidence that there is an association between the profit and credit loss expense. On the whole, the present study explores the profitability and the success of the financial organization.]]>

<![CDATA[Non-Banking Financial Corporations are playing a major role in the financial market with respect to providing loan facilities to the business. It is an integral the financial system of any country. It leads to improvise the employment opportunities and economic development. The NBFCs are becomes an important stimulant of credit creation and credit control tool of central banks of the respective countries. The dispersal of loans and advances provided to individuals and the companies are contained the credit risk for the NBFCs. Gumrarathi (2010) study reveals that most of the non-banking financial corporation’s business operations are holding a high credit risk in lending. It shows that most of the lending transacted with small and medium level organizations, which is having a probability of high-risk class. The NBFCs are already encountering various issues such as high fund cost, poor industrial development, and huge competition among the NBFCs and also with commercial banks. The non-performing assets are another kind of big issue in reducing the profitability. In this juncture, the management of this credit risk is one of the prominent challenges of the Non-Banking Financial Corporations. Because the credit risk is the direct risk and their whole business life survival is based on the money which is invested on loans. The credit risk measures are coming into existence to mitigate the losses arise through the non-performing assets (NPA). The present study aims to analyze the various strategies adopted by the selected NBFCs. It is attempted to find out the credit risk measurement and controls systems of NBFCs. The study also analyzes the relationship between the credit risk measures of corporations and its profitability. Present study is adopted the descriptive research method to carry out the study. It is purely based on the secondary data sources such as financial statements, published data of NBFCs and data published in journals. The collected data is analyzed by applying appropriate econometric tools such as stationarity, cointegration, and granger causality to find the relationship among the variables. Based on the data analysis, the results are interpreted and conclusions are made. The present study provides the strong evidences of strong relationship among the credit risk management, control of non-performing assets and the profitability of the NBFCs.]]>

<![CDATA[Earthquake is natural event due to release of energy suddenly from within that creates seismic waves. The vibrations are usually caused by movement of earth's plates. It cannot be predicted when they are coming. Therefore, need to build an early warning system. It is for anticipation of save the community when an earthquake occurs. It provides solutions to minimize the impact of earthquake events. This system uses accelerometer sensor and arduino nano as a main controller and it is accompanied by Blynk application. This works for sent notification via smartphone. This tool has been successfully designed with manual testing to be able to see the sensitivity of earthquake sensor made. Accelerometer sensor works is using Tilt Method. Accelerometer sensor will tilt on surface as parable of earthquake. Accelerometer sensor will send vibration signal when earthquake occurs. Signal processing is done by Arduino nano as the main controller in system. If the signal is received by sensor then value of earthquake will be displayed on LCD screen. Status of earthquake was separated into 4 levels such as standby, alert, dangerous, dangerous and dangerous. After earthquake value appears on the LCD screen and the status is known then buzzer will sound. It indicates that the earthquake warning alarm is properly functioning. Next, NodeMCU also sends information to Blynk application, which is used as a notification and monitoring of earthquake conditions. Buzzer will sound as a warning alarm to notify peoples to save themselves. This sensor has three output coordinate points, namely X, Y, Z, which have analog values on Arduino Nano. This analog value can be converted into Richter Scale. Based on experimental results, an analog value is 100 – 400.]]>
