Symmetric encryption using preshared public parameters for a secure TFTP protocol / Nur Nabila Mohamed

Due to rapid development of communication technology of constrained embedded systems, it is important to deal with security including integrity and confidentiality to maintain the accuracy while distributing data safely and efficiently. Trivial File Transfer Protocol (TFTP) is used for transferring files quickly and simply. The main advantage of using TFTP in embedded system is because of its speed and simplicity but it provides no security mechanism which makes it vulnerable to various attacks. This work proposes the security implementation of Diffie Heilman Key Exchange (DHKE) by presharing public parameters for mutual authentication that enables two communicating parties to achieve the same secret key. The concept is integrated with compression and encryption technique to significantly reduce the computational requirements in TFTP communication. The experiment is done on two embedded devices to perform the functionality of key exchange and data encryption in TFTP. The results were analyzed in terms of confidentiality and integrity of data, execution time, file scheme throughput, compression ratio, average file reduction percentage and transmission time using variable file size. The results show that the proposed work based on DHKE using preshared public parameters includes compression and encryption technique is an efficient solution to mitigate Man In The Middle (MITM) attack as well as manage security issues and large file sizes. The purpose of TFTP which acts as a simple file transfer protocol would bring huge advantages to be employed in ubiquitous computing environment if the basic security strategies were integrated with this protocol

Local agenda 21 : action plan for sustainable development : case study for Shah Alam

Sustainable development, which has been defined as a means to meet the needs of the present without compromising on the ability of future generations to meet their needs, is not a new term these days. One of the initiatives that have been taken by the government of Malaysia in realizing the idea of sustainable development is through the implementation of Local Agenda 21 (LA21). LA21 is a global action plan or blueprint for sustainable development at local level, which was adopted at the Earth Summit in Rio de Janeiro in 1992. LA21 is a reflection of a common consensus and political commitment of countries globally on sustaining development and environment cooperation. As such, this paper explains the role of LA21 as one of the efforts by the Malaysian government in achieving sustainable development. The objective of this paper is to describe the implementation of LA21 programs and activities carried out and planned by the local authority, community and private sector towards achieving sustainable development. A descriptive analysis was used to describe the Shah Alam’s LA21 projects in promoting sustainable development. The outcomes illustrated the significance of LA21 projects in facilitating Malaysia to achieve sustainable development

Robots and autistic children: a review

In accordance with the advancement in robotics and the scholarly literature, the extents of utilizing robots for autistic children are widened and could be a promising method for individual with Autism Spectrum Disorder (ASD) treatments, where the different form of robot (humanoid, non-humanoid, animal-like, toy, and kits) can be employed effectively as a support tool to augment the learning skills and rehabilitate of the individual with Autism Spectrum Disorder (ASD). Thus, the robots were exploited for ASD children in different aspects namely; modelling, teaching, and skills practicing; testing, highlighting and evaluating; providing feedback or encouragement; join Attention; eliciting social behaviours; emotion recognition and expression; imitation; vocalization; turn-taking; and diagnostic. The related literature published recently in journals and conferences is taken into account. In this paper, we review the use of robots that help in the therapy of individuals with Autism Spectrum Disorder (ASD). The articles on using robots for autistic children rehabilitation and education which reported results of experiments on a number of participants were implicated. After looking in digital libraries under this criteria, and excluding non-related, and duplicated studies, 39 studies have been found. The findings were focused mainly on the social communication skills of autistic children and how the extent of the robots mitigate their stereotyped behaviours. Deeper research is required in this area to cover all applications of robotic on autistic children in order to design feasible and low-cost robots that ensure provide high validity

Religions that can be legally practised and professed in Malaysia / Siti Nabila Huda Zaidisham…[et al.]

The vitality of religion in Malaysia has been acknowledged by the Constitution by referring to Article 11 in which freedom of religion has been included as part and parcel of Fundamental Liberties granted to all citizen of Malaysia including those residing in the country regardless of his citizenship and domicile. Furthermore, Article 3(1) acknowledges Islam as the Federation's religion and allows other religions to be practised in peace and harmony. Article 3 symbolises the sense of unity, tolerance and respect between religions. The emergence of new cults and new religious groups throughout the world became an issue when these religions were not accepted by Malaysians. Thus, it is vital to determine which religions can be practised by Malaysians without being punished. The aim of this research has led the researchers to analyse Article 3 and Article 11 of the Constitution in depth regarding the religions that can be legally practised and professed in Malaysia and to come out with suggestions for appropriate incorporation to be made into the Constitution regarding religions that can be legally professed and practised besides making suggestions on what are the elements in order to infer a religion is an established religion. It is hoped that the research will provide better understanding and awareness regarding the religions that can be legally practised and professed in Malaysia and the rights to freedom of religion granted by the Constitution

Positive and Negative Effects of Research and Development

This study aims to examine the effects of research and development expenditure on economic growth and carbon dioxide emission in the panel data for the period of 1996-2011 from 5 nations (Germany, Russian Federation, United Kingdom, United States and Canada). The panel co-integration was conducted and the results show that there is co-integrated relationship among the variables (R&D, GDP, Energy Use and Carbon Dioxide Emission). Then the FMOLS test was performed and the findings explain that energy use and R&D are the determinants of GDP. Results from FMOLS show that energy use and R&D are the determinants of GDP. Energy use and GDP are the determinants of carbon dioxide emission. Results from DOLS show that R&D is important to boost economic growth while energy use, GDP and R&D can have deleterious effects on carbon dioxide emission. Therefore, it is important to control the R&D expenditure to balance economic growth and environmental conservation.

Design of online transaction model on traditional industry in order to increase turnover and benefits

Online transactions are transactions made sellers and buyers online through the Internet media, there is no direct encounter between buyers and sellers. Currently with the rapid development of technology and the Internet in Indonesia, has had a great impact on the change of industrial business. That is starting from the way advertising, buying and selling, how to interact between humans, and so forth. With e-commerce has changed a lot in the process of buying and selling. Panda Alami is one of the banana chips industry established since 1998 in Cipadang Pesawaran village. This banana chips industry still uses manual way in transaction process. To increase the turnover and profit that is the purpose of this study, the transaction model is developed with SDLC (System Development Life Cycle) and software used to design and design this application is PHP programming language, MySQL Database and Adobe Photoshop CS3. Features include product search, order, delivery and payment confirmation and thus provide integration of the entire inventory unit sales network. An equally important factor is trust. In this process trust is the main capital. Because without the trust of both parties, then the process of online transactions can not happen and done

Breast cancer management pathways during the COVID-19 pandemic: outcomes from the UK ‘Alert Level 4’ phase of the B-MaP-C study

Abstract: Background: The B-MaP-C study aimed to determine alterations to breast cancer (BC) management during the peak transmission period of the UK COVID-19 pandemic and the potential impact of these treatment decisions. Methods: This was a national cohort study of patients with early BC undergoing multidisciplinary team (MDT)-guided treatment recommendations during the pandemic, designated ‘standard’ or ‘COVID-altered’, in the preoperative, operative and post-operative setting. Findings: Of 3776 patients (from 64 UK units) in the study, 2246 (59%) had ‘COVID-altered’ management. ‘Bridging’ endocrine therapy was used (n = 951) where theatre capacity was reduced. There was increasing access to COVID-19 low-risk theatres during the study period (59%). In line with national guidance, immediate breast reconstruction was avoided (n = 299). Where adjuvant chemotherapy was omitted (n = 81), the median benefit was only 3% (IQR 2–9%) using ‘NHS Predict’. There was the rapid adoption of new evidence-based hypofractionated radiotherapy (n = 781, from 46 units). Only 14 patients (1%) tested positive for SARS-CoV-2 during their treatment journey. Conclusions: The majority of ‘COVID-altered’ management decisions were largely in line with pre-COVID evidence-based guidelines, implying that breast cancer survival outcomes are unlikely to be negatively impacted by the pandemic. However, in this study, the potential impact of delays to BC presentation or diagnosis remains unknown

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Hybrid cryptographic approach for internet of things applications: a review

Cryptography is described as the study of encrypting or secret Cryptography is described as the study of encrypting or secret writing of data using logical and mathematical principles to protect information. This technique has grown in importance in computing technologies for banking services, medical systems, transportation and other Internet of Things (IoT)-based applications which have been subjected to increasing security concerns. In cryptography, each scheme is built with its own respective strength, but the implementation of single cryptographic scheme into the system has some disadvantages.For instance, symmetric encryption method provides a cost effective technique of securing data without compromi singsecurity. However, sharing the secret key is a vital problem. On the other hand the asymmetric scheme solves the secret key distribution issue; yet the standalone technique is slow and consumes more computer resources compared to the symmetric encryption. In contrast, hashing function generates a unique and fixed-length signature for a message to provide data integrity but the method is only a one-way function which is infeasible to invert. As an alternative to solve the security weakness of every single scheme, integration of several cryptographic of every single scheme, integration of several cryp to graphicschemes which are also called the hybridization techniqueis being proposed offering the efficiency of securing data and solving the issue of key distribution. Herein, a review study of articles related to hybrid cryptographic approach from 2013 to 2018 is presented. Current IoT domains that implemented hybrid approaches were identified and the review was conducted according to the category of the domain. The significant findings from this literature review included the exploration of various IoT domains that implemented hybrid cryptographic techniques for improving performance in related works. From the findings,it can be concluded that the hybrid cryptographic approach has been implemented in many IoT cloud computing services. In addition, AES and ECC have been found to be the most popular methods used in the hybrid approach due to its computing speed and security resistance among other schemes
