AESTHETIC VALUE OF RE-USE WASTE MATERIALS AS A PANACEA FOR ENVIRONMENTAL PROTECTION (An Appraisal of Oligbinde's Creative Works)
Authors: Oligbinde S.R  , Adesanya C.O  , Oyeniyi E O
Published: August 2022

Discarded plastic and bottle tops are unwanted and seen as unusable materials that the initial user has no further use for or no longer considers of any significant value to retain. They are considered waste, thus, discarded after primary use. The indiscriminate disposal of such waste amounts to an alarming volume of them, however, wastes can be managed through recycling, repurposing and if well managed, a man stands at a vantage point economically, socially, and more importantly aesthetically – which affects our health on short and long terms. This paper examines the plastic sculptures of Oligbinde Rotimi with the concept of turning plastic waste into objects of aesthetic made from discarded plastics that are purposively selected for formal and contextual analysis. These works were produced as a source of inspiration for others to gainfully redeploy any plastic they see within their enabling environment to lay their hands on and thereby save the planet committed to us. Photographs of works are taken and the procedures involved in executing the works were highlighted.

The evolution of the concept of information warfare in the modern information society of the post-truth era
Authors: Bryczek-Wróbel Patrycja , Moszczyński Maciej
Published: August 2022

Objectives

Compare selected concepts of information warfare and show the evolution of the Western concept of WI,resulting from the development of the information society, social-media and the resources by which information warfare is conducted.

Methods

The research method used is a systematic review of Western political science literature, as well as military literature, publications on international relations, international politics, security and cyber security from the perspective of information warfare. Techniques such as analysis of background material, causal analysis and scientific and self-observation in this area were used, taking into account the dynamics of technological and geopolitical changes occurring in the modern information society.

Results

The analysis made it possible to show the evolution of the Western concept of information warfare and outline the main differences from the concept of information warfare adopted by the Russian Federation. The study also points out the threats to the information society posed by the realities of modern information warfare.

Conclusions

The Western conception of WI differs from that of the Russian Federation, placing the emphasis on WI as technological warfare, while the Russian Federation and the People's Republic of China (PRC) place the emphasis on psychological warfare first. This discrepancy could pose a significant threat to the information environment of Western democracies, since the weakest link in the security of not only an information system, but also an information system, is the human being. This is well known not only to hackers, cyber criminals, but also to hostile state or non-state forces that conduct WI against Western countries.
The Exploring Ondel-Ondel Village: A Study of the Network and the Working System of Kramat Pulo’s Ondel-Ondel
Authors: Akhirun Layosibana , Septiady Yophie
Published: August 2022

This study aims to provide an overview of the Kramat Pulo community’s network and the working system on performances of ondel-ondel. This study uses a qualitative approach. The data were collected using in-depth interviews, observation, and documentation. The data that has been obtained is then analyzed using qualitative inductive analysis. The results show that the ondel-ondel network system of the Kramat Pulo community consists of several divisions of roles: owners, managers, studio members, entrepreneurs, field coordinators, buskers, and the Government of the Special Capital Region of Jakarta. The network system then establishes and supports the ondel-ondel working system: ondel-ondel performances and ondel-ondel busking. Ondel-ondel performances are generally only practised once or twice weekly. In contrast, ondel-ondel busking activities are practiced daily by Kramat Pulo teenagers. On the other hand, the relationship between the studio owner and entrepreneur and Kramat Pulo teenagers who want to parade ondel-ondel for busking on the streets can be done in two ways: rental or profit-sharing. This relationship is based on a belief system maintained by the Kramat Pulo community. Therefore, it is recommended that the Government of the Special Capital Region of Jakarta make unique spots for Ondel-ondel performances. In addition, coordination is needed between the field coordinator and the Government of the Special Capital Region of Jakarta to arrange ondel-ondel busking activities routes to create order without losing cultural nuances. In this case, Betawi indigenous people carry out their traditions by parading ondel-ondel to surround the village.

David Hume's Discourse “On Miracles”: An Evaluative Study
Authors: Joseph T. Ekong, Rev. Fr. , O.P
Published: August 2022

In this paper my aim is to discuss Hume's definition of miracles. I shall also address the problem of "causality" and "induction" as themes related to Hume's thesis on miracles, in order to have a better understanding of his position. This paper assumes the existence of God, as revealed in Christian Scripture, but does not have as its purpose the attempt to prove it, although God's existence and the working of miracles in this world are, without doubt, related. Finally, adopting an analytic and critical style, this work will assess the putative worth, if any, of Hume’s anti-miracle arguments, with an advocacy for a synergy between faith and reason, in religious practices.
Fabrication of Thermoelectric Module from Efficient Earth Abundant Thermoelectric Materials
Authors: Rahman Md. Ataur
Published: August 2022

To develop a power generation technology, we proposed low-cost and nontoxic earth abundant thermoelectric materials consisting of n-type and p-type iron oxides. For high temperature applications of power generation, thermoelectric materials consisting of oxide assure better thermoelectric properties. In this research work, thermoelectric module has been fabricated with three pairs of p-type and n-type thermoelectric materials. In this context, we used Hematite (α-Fe2O3) as thermoelectric material which is naturally n-type. By doping Zn, α-Fe2O3 turned into p-type. Using spin coating method, n-type α-Fe2O3 and p-type Zn doped α-Fe2O3 (Zn:αFe2O3) have been synthesized. For the p-type and n-type legs of the thermoelectric module, the dense bulk samples of α-Fe2O3 have been produced by cold isostatic pressing at 450 MPa for 15 min. Six-leg thermoelectric module consisting of three pairs of n-type α-Fe2O3 and p-type Zn:α-Fe2O3 bulks of 3 × 5 mm2 cross-section and heights of 10.5 mm were fabricated. At an operating temperature of 893 K with a temperature difference of 471 K, an open circuit voltage of 744 mV was generated.

This research discusses what variables can affect employee job satisfaction and have an impact on employee work. The variables are conflicts of roles, authorities, job satisfaction, and performance. The purpose of this study is to find out how much direct and indirect influence on the performance of employees of construction companies. The analysis method used is path analysis, this is considered more suitable for primary data taken with research instruments in the form of questionnaires to respondents who are in these companies. The results of the research obtained are conflicts of roles and authorities that have a direct influence on job satisfaction and have a direct and indirect influence on performance. Meanwhile, job satisfaction has a direct impact on employee performance, therefore construction companies are expected to pay attention to employee job satisfaction, to improve employee performance, which is expected by the company. Job satisfaction is an affective or emotional response to various facets or aspects of a person's work so job satisfaction is not a single concept. A person can be relatively satisfied with one aspect of the work and dissatisfied with one or more other aspects. Job satisfaction is a positive attitude of labor to its work, which arises on the basis of an assessment of the work situation.
Hume's Critique of Locke’s Variant Of "Social Contract Theory”: A Ratiocinative Assessment
Authors: JOSEPH T. EKONG REV. FR. , O.P
Published: August 2022

David Hume (1711-1776) has long been considered a severe denunciator of 'social contract theory', and this interpretation has implicitly premised a perspective that lays heavy weight on the importance of social contract in the history of political thought. This work presents Hume's critique of the Lockean version of the social contract, and identifies the issues responsible for such criticism. In Book 3 of Hume's Treatise on Human Nature (henceforth T), Hume displays his systematic criticism of social contract theory. Hume did not consider social contract theory as an important trend in the history of political thought. One of his points was that 'social contract theory' was quite new, strange and 'heterodoxical' in politics. This work offers an appraisal of Hume’s stance on the Lockean variant of “Social Contract Theory” and proposes a more judicious textual reading of his contributions in this regard.

This study aims to determine the factors that influence development performance in Aceh Selatan, as a district located in the southern part of Aceh, Indonesia, with the objects being the village government leadership, community participation, and monitoring and evaluation of the implementation of development programs, and the performance of Development Performance achievements. The total population was 25,661 people. The sample selection technique used was the probability sampling technique. The Stratified Proportional Random Sampling was used as a method of sampling. While the determination of the minimum sample size in this study was determined using the Slovin formula so that the total sample size was 400 people. Data were collected by distributing questionnaires which were measured using a Likert scale. The data were analyzed using the SPSS application. The results prove on underdeveloped villages in Aceh Selatan, the Village Government Leadership, Community Participation, Monitoring & Evaluation, and Development Performance are not in a good performance; the village government leadership, community participation, and monitoring & evaluation positively and partially affect development performance; and Village government leadership, community participation, monitoring and evaluation positively and simultaneously affect Development Performance. These findings also explain that the model for improving development performance in Aceh Selatan is a function of strengthening government leadership, increasing community participation, and strengthening monitoring & evaluation.

Published: August 2022

Presentamos un paciente masculino de 40 años, con antecedente de cardiopatía isquémica, con evidencia de trombo ventricular derecho y disfunción sistólica. Reportamos el caso exitoso tras la terapia crónica con anticoagulación oral. Después de 2 años de seguimiento, el paciente se mantiene estable sin presentar datos de embolia pulmonar, falla cardíaca, arritmias, sangrado o necesidad de manejo invasivo, sin presentar remisión del trombo. La literatura actual no muestra un consenso en el tratamiento ideal en estos pacientes, se requiere de la evaluación integral del riesgo/beneficio aunado a la experiencia de cada centro en la opción terapéutica empleada.

Introduction. Prostate cancer antigen-3 (PCA3) is a genetic biomarker, which got widespread and demonstrated high diagnostic potential. This gene expresses only in prostate gland tissue, furthermore, malignant prostate neoplastic transformation leads to 70 – 100 time overexpression of it. Polyadenylated matrix RNA (mRNA) is a functional product of this gene, which do not translating into protein. Gene contains of four introns and three exon. Product of PCA’s gene detecting in post massage urine using polymerase chain reaction (PCR) in combination with reverse transcription. It could use as prognostic biomarker in patients with first negative biopsy or before it performing. Moreover, index of PCA3 can be useful in detecting tumor aggressiveness and decisions about further treatment options. Taking into account these facts, patients with high initial PSA level can avoid unnecessary biopsies.
Objective: to determine critical cut-off value of PCA3 index as prognostic biomarker of PCa development.
Materials and methods. Research based on routine and special test’s data of 243 men in Institute of Urology, National Academy of Medical Sciences of Ukraine in period of 2015–2020 year. RNA extraction from postmassage urine samples performed using RNeasy (Qiagen) kit. Statistical analysis performed using SPSS Statistics 19.0 (IBM SPSS Statistics 19.0) та SAS 12.0 (IBM Statistical Analysis System 12.0). Critical cut-off values determined using three methods: calculating of average value and (Xave) and standard deviation (SD) of it, Heiner index, and Youden’s index. Evaluation of optimality of determined critical cut-off values performed by comparative analysis using index of positive prognosis (IPP), index of negative prognosis (INP), diagnostic accuracy of method (DAM), Sp and Se for each of used methods.
Results and discussion. First method demonstrated than 97,5 % of all results, which means absent of disease, was below critical cut-off values, due to statistical deviations and accurate demonstrate than in case of asymmetry or multimodal distribution this method was unsatisfied. Wherein IPP was 95 %, INP – 72 %, DAM – 78 %, Sp – 97,5 % and Se – 52 %. Calculation of PCA3 index area under ROC-curve was 0,810 (0,771–0,849). Using Heiner’s method critical cut-off value of PCA3 index was 14,0 с. u., where in IPP was 75 %, INP – 82 %, DAM – 78 %, Sp – 78 % and Se – 78 %. Critical cut-off values of PCA3 index 33,4 c. u. which calculated by Youden’s index demonstrated IPP – 98 %, INP – 73 %, DAM – 80 %, Sp – 99 % and Se – 57 %.
Conclusions. The most optimal critical cut-off value for PCA3 index was determined using Youden’s index and was 33,4 c. u.
