Enhanced MQTT Architecture for Smart Supply Chain

In industry 4.0, the use of smart supply chains has become necessary in order to overcome the shortcomings of traditional supply chains, such as overstocking, delivery delays, and stock out.However, the use of smart supply chains has introduced new security challenges because of the internet of things (IOT) constraint nature.Thus, the problem raised is ensuring the supply chain security requirements while taking into consideration the properties of the constraint environment.For this purpose, this paper aims to strengthen the authentication and data transmitting processes of the Message Queuing Telemetry Transport(MQTT) protocol, as the most used protocol for communication in the IOT environment, using blockchain and smart contracts.The new MQTT architecture allows to avoid a single point of failure, to ensure data immutability and to automatize the authentication mechanism as well as the publishing and the subscribing processes.In addition, the use of a one-time password (OTP) instead of a permanent one is another security measure used to protect the architecture from identity spoofing.The new architecture comprises three phases: Registration, Connection, and Publishing.Each phase is automatically controlled by a smart contract.For attack simulation tests, the smart contracts are implemented in a remix environment.The results of the simulation tests show that the new architecture is robust and resistant to different attacks.

Soil Subsidence on Peat Land Due to Rainfall; Case Study of Pundu Region, Central Kalimantan

This study aims to determine the extent to which rainfall affects soil subsidence on peatlands in PT. BGA. TBk., Pundu, Central Kalimantan. The research was conducted at Katari Estate, PT BGA, Tbk. Pundu Central Kalimantan in September - December 2019. The research method used is the survey method, which consists of two stages, namely the preliminary survey and the main survey. A preliminary survey was conducted to determine the research location while the main survey was carried out to obtain research data, namely monthly rainfall data and subdidence in 2014 – 2018. To see the relationship between rainfall and land subsidence, Linear and Polynomial Regressions were made at lag 1, lag 2, and lag 3. Regression with lag 1 is the relationship between rainfall last year with land subsidence this year and rainfall last month with land subsidence on peatlands this month in the same year, and so on for lag 2 and lag 3. The results show that the regression between The best rainfall with soil subsidence on peatlands is the annual Lag 1 Linear Regression. This means that last year's rainfall has an effect on this year's subsidence. with the equation, Y = - 0.004 X + 1.209, where R² = 0.582. This equation is obtained from the correlation between X (average rainfall) from 2015-2018 and Y is soil subsidence also from 2015-2018. While the regression between last month's rainfall and this month's land subsidence in each year (2015 – 2018), shows a low correlation.
Randomness Analysis of Secured One-Time Password Generation Scheme for Financial Ecosystems

In financial transactions, digital payments have increased exponentially during the novel coronavirus (COVID-19) pandemic. Different wallets are used in which secured one-time password (OTP) generations are required for login to various banking services. Recent research has suggested an OTP calculation scheme using the Vigenère cipher. The schemes are useful for financial applications, but the generation is not significantly random. As the strength of the OTP depends basically on its generation randomness, so motivated by the same, in this paper, we propose a randomness-based scheme for OTP generation. To validate the security of the generated OTP, we carry out a randomness analysis. We compare our work; they have used only SHA variants to implement the method but we further extend their method by using other algorithms as well.

A Study on the Digital Literacy Capacity and Perception of New College Students

The purpose of this study is to present a liberal arts education plan that considers digital literacy capabilities by examining the digital literacy capabilities and perceptions of college students. First, students' ability to solve problems related to digital devices is low. The ability to solve access failures or treat malicious code was very high with a negative response rate of around 47%. Second, college students' perception of digital ethics, such as the ability to test report plagiarism, was generally low. Third, it was found that students like video materials, but prefer paper books to e-books. Fourth, compared to the preference for YouTube media, the ability to edit videos using professional programs was found to be poor. Fifth, it was found that the experience of taking liberal arts courses related to digital literacy did not reach the major subjects. Through these results, it is necessary to change the direction of literacy ability so that information and knowledge can be obtained through e-books, establish digital citizenship and ethical awareness more thoroughly, and develop the ability as a producer, not a digital consumer.
A Study on the Use of Objectivity-Securing Strategy Expressions in Korean Academic Papers

The purpose of this study is to examine the use of language expressions as strategies for objectivity in Korean academic papers. To this end, based on statistical data from RISS, a service provided by the Korea Educational Information Service, 60 most recently studied and highly utilized academic papers were selected among papers in the fields of humanities, social science, and education. These papers have a total of 367,520 words, and before closely examining the expressions as strategies for objectivity in the paper, the genre characteristics of the academic paper were reviewed and the strategies for objectivity summarized in the previous study was referred. Since then, expressions that are objectification strategy of academic papers have been extracted, and as a result, language expressions used as strategies for objectivity in academic papers have been divided into 'nominalization', 'passive form', 'depersonalization', and 'tense'. Unlike previous studies, this study is meaningful in that it examines expressions as strategies for objectivity that reflects the characteristics of academic papers only, and summarizes the expression used together, frequency, and the context of expressions as strategies for objectivity.
