Hebatnya al-Quran sebagai panduan hidup manusia sejagat. Hampir 1/5 daripada ayat-ayatnya memperihalkan secara langsung berkenaan akhlak manusia. Akhlak terpuji membawa rahmat tidak terperi kepada umta manusia sejagat. Hal ini menjelaskan betapa akhlak yang sempurna dititikberatkan oleh Islam. Manusia dan komunikasi tidak boleh dipisahkan, bahkan dalam diam mereka turut berkomunikasi. Begitu juga dengan akhlak, dalam setiap aktiviti manusia ia mesti menjadi tunjang utama. Pekerjaan dipandang mulia jika dilaksana dengan berakhlak, begitujuga dengan komunikasi sesama manusia. Akhlak dapat diertikan dimaksudkan sebagai keperibadian, sahsiah dan sifat-sifat yang merujuk kepada perbuatan mulia. Kertas kerja konseptual ini membincangkan maksud akhlak, komunikasi sesama manusia serta kedudukan akhlak dalam komunikasi khususnya dalam masyarakat Melayu. Dapatan kajian merumuskan bahawa akhlak komunikasi menjadi para syarat kepada ujudnya hubungan yang sejahtera sesama manusia. Namun dalam zaman mutakhir ini didapati terlalu ramai manusia meminggirkan akhlak ketika berkomunikasi lantas wujudlah hubungan yang sumbang serta canggung dalam komunikasi sesama mereka

Published: August 2021

Tulisan ini mendiskusikan tentang hubungan antara Siak dan Johor dan VOC, Belanda. Siak merupakan pintu gerbang Johor dari arah darat Sumatera, manakala Sungai Siak pula merupakan urat nadi pengangkutan masa itu karena Sungai Siak termasuk sungai yang memiliki kedalaman sehingga memudahkan kapal-kapal besar berlayar menuju Selat Melaka. Hubungan di antara Siak dan VOC sama saja dengan hubungan Johor dengan VOC karena pada masa itu kawasan Siak pula merupakan kawasan Johor. Hal ini bermakna apa yang berlaku ke atas Johor, maka berlaku pula di Siak. Akan tetapi, bagi Belanda, Sungai Siak yang bermula dari Selat Malaka merupakan jalur lalu lintas penting bahkan Belanda amat mementingkan Sungai Siak tersebut untuk melancarkan perjalanannya ke daerah.

Published: August 2021

Insecticides are used widely to control insect pests affecting cowpea and their residues are often deposited in the soil. This may impact the physico-chemical characteristics of the soil and the plant health. This study was designed to investigate the growth response of cowpea treated with lambda-cyhalothrin and dimethoate and the insecticides influence on the physico-chemical characteristics of the soil. Three cowpea seeds were planted per polyethylene bag containing top soil, and later thinned to two plants. The insecticides were assayed singly or combined. The insecticides were applied at the pre-flowering (30th day), flowering (50th day) and at podding (70th day) stages of cowpea growth. The physico-chemical parameters of treated soils were assayed. Treated soils with lambdacyhalothrin and dimethoate and the control were slightly acidic with pH varying from 5.78 to 6.55. Soil organic matter and soil nutrients such as nitrogen, phosphorous, potassium and sodium had lowest values in untreated soil; they had highest values in soil treated with combined insecticides. Lambda-cyhalothrin and dimethoate treatments elicited diverse response from the cowpea plant. Generally, there were slight increase in the vegetative parameters, yield and pod dimensions of treated plants when compared with the control. These insecticides also increased the root nodules, root length and dry weight of cowpea at different concentrations. The combination of these insecticides had positive effect on cowpea without adverse influence on the yield and as well as the soil physicochemical properties.

Published: August 2021

Object and purpose of research. The study addresses the technogenic underwater noise issues with a view to environmental and competitive challenges, as well as the Navy interests. Materials and methods. The issues studied in this investigation are relatively new for the Russian shipbuilding, shipping and marine activities, and the first step to systematic studies should be formulation of a technogenic noise problem as a physical phenomenon, which have to be considered in the state marine and transportation policy. The paper uses results of design studies performed in Krylov State research Centre, as well as information from mass media. The main sources of the technogenic underwater noise are coastal industries and port infrastructure, marine oil & gas structures, transport and ice-breaking vessels. Main results. It is concluded that a special-purpose integrated target program should be formulated and performed, whose result would be systematization of research and design projects aimed at the analysis, regulation and standardization of technogenic underwater noise parameters of various marine technologies. Conclusion. Technogenic underwater noise is directly related to the safety of marine ecosystems. In addition, it is a factor of commercial and large-scale economic competition in the international community. In future the technogenic underwater noise of marine facilities may become an instrument of competition for the opportunity and right to exploit Russian oil & gas deposits, as well as to use Russian Arctic routes. Against the backdrop of these two factors, the Navy interests are obviously to raise the efficiency of fixed and mobile sonar systems in the environment of high technogenic noise produced by civil marine activities.

Published: August 2021

The introduction of innovative e-learning and teaching methods at universities of technologies necessitates the examining of students’ perceptions of these methods in the promotion of student success. In South Africa, the majority of first-year students are not exposed to technology-aided learning methodology during their high school career, especially those from disadvantaged demographics. The purpose of the study is to examine student perceptions regarding their experience of e-learning at a South African university of technology with specific reference to the success of first-year students from disadvantaged backgrounds. Using qualitative research methods through semi-structured interviews, the researchers discovered that first-year students from disadvantaged backgrounds are experiencing challenges in terms of access to resources such as computers, laptops and reliable internet connection. Furthermore, inadequate training on the use of online resources and unsatisfactory performance during online assessment were discovered and these are heightened by the Covid-19 pandemic. First-year students from disadvantaged backgrounds are exposed to a variety of barriers that have an adverse impact on their success. The study recommends that higher education institutes provide the necessary resources to facilitate seamless assimilation of first-year students into the new environment.

Authors: Baloyi Gezani
Published: August 2021

Teaching adult students in the context of the Fourth Industrial Revolution poses numerous difficulties in the global higher education context. Unisa students are generally adults who are working, but younger students also register with the institution, and they require support. The paper focuses on the adult students in the ABET department, which falls within the School of Educational Studies. The ABET student cohort comprises both older and younger students who are keen to learn. However, the lack of internet connectivity makes teaching and supporting them during the Covid-19 pandemic difficult, with a number of students situated in the rural areas. For the study, the researcher used the community of inquiry theoretical framework, which promotes interaction between student, teacher and content. At Unisa, teaching and learning take place on the myUnisa learning management system. The findings suggest that some students do not have the necessary skills to use myUnisa. The lack of skills in the use of technologies is a cause for concern.

Published: August 2021

It has become evident that the global climate is changing rapidly over the past few decades. The variation and change in the global climatic factors have a notable impact on the local climate of a region. The changing climate is widely regarded as one of the most serious global health threats of the 21st century. Among various kinds of diseases, the most vulnerable to these changes are vector-borne diseases. In the Indian context, particularly Delhi city is the most vulnerable to dengue, a kind of vector-borne disease having its highest impact. We sought to identify and explore the correlation and influence of the global climatic phenomena and local climatic factors with the reported number of dengue cases in Delhi. The temporal expansions of reported dengue cases in Delhi have a variation from its first major outbreak in the city during the year 1996 to 2015. A statistical tool like Pearson Product Moment Correlation (PPMC) is used in this study to establish the interrelationship and the level of impact and local climatic variation on dengue. An exceptional negative correlation value of r = -0.82 between the monsoon index and the dengue incidences was reported during the positive years and also maintains a very high positive correlation with other global climatic indices. The study here finds that there is a strong correlation of climatic variation which further influences the epidemiology of dengue in Delhi.
