ABSTRACT
The objective of this paper is to review the theoretical, conceptual and empirical frameworks around the perception of risk as a rational, deliberate, planned and systematic process of contingencies and threats. A documentary and retrospective study was carried out with a non-probabilistic selection of sources indexed in international repositories, considering the journal's impact factor and the author's citation index. A model was established based on the evaluative consensus of expert judges in the subjects, although the research design limited these findings to the study scenario, suggesting the extension of the work towards lines of research concerning normative, technological and strategic trust with respect to to civil protection.

ABSTRACT
The future mechanism from new technology to transgenic products, hydrogen fuel battery and automobile components industry are analyzed in detail. Put forward to the implementation of their products and put their possibilities into practice. Specific response measures are pointed out in two respects, indicating that they are urgently needed to run the factory products. In additional the products shall be established in Africa in order to promote new and innovation. It can be acquired through train in and between factories besides the school. Due to its low labour and undeveloped industry many opportunity will await us to mine its countless chance and profit. Like in Africa they can loan with urgent and above two because of their development mechanism. So if endeavor is done many new project will be found by us together. Let us continue to pay attention to Africa for better benefit and common development. The above two as important new products need to be paid more attention whether are they become launch one need some time to verify effectiveness.

ABSTRACT
The latest COVID -19 corona virus disease outbreak is responsible for a highly pathogenic corona virus (SARS-CoV-2). Since no vaccines or licensed drugs are currently available, sanitization interventions appear to be important to help delay the transmission of COVID -19. For regular hand hygiene, WHO suggested alcohol-based hand sanitizers, containing predominantly of hydrogen peroxide, ethanol, and isopropyl alcohol in various combinations. When misused, these preparations can become harmful to human health. The key goal of the new analysis is to demonstrate the toxicity and serious adverse effects.

ABSTRACT
The future trends from military to nuclear power industry are analyzed in detail. Put forward to the implementation of military, high technology and nuclear power and put their possibilities into practice. Specific response measures are pointed out in these three respects, indicating that they are urgently needed to run the factory products. In additional the nuclear power plant shall be established in Africa in order to promote new and non-contamination energy. Due to its low labour and undeveloped industry many opportunity will await us to mine its countless challenge. Like south Africa they can live together with better status because of their development. So if endeavor is imported many new project will be found by us together. Let us continue to pay attention to Africa for better benefit and common development.

ABSTRACT
The study investigates the impact of electronic banking on the performance of deposit money banks in Nigeria using quarterly data from the first quarter of 2010 the quarter of 2018 from the Central Bank of Nigeria statistical bulletin. It tested the response of the variables of interest, automated teller machine (ATM), point of sale (POS), mobile banking (MOBE), and web pay (WEPA) on net interest margin (NIMA).It employed the use of Jarque Bera normality and diagnostic tests, Augmented Dickey fuller unit root test for stationarity. The result shows that ATM, POS and WEPA are not significant to NIMA while MOBE is positively related and significant to NIMA. The study recommended that customers should be encouraged to use mobile banking platform.

ABSTRACT
This study examined the impact of digitalization on organizational performance in Logistics firms in Ifako-Ijaye LGA of Lagos State. Five research questions and two hypotheses guided the study. In line with the objective of the study, descriptive research design was adopted. The population of the study was staff of 108 logistics firms in Ifako-Ijaye LGA of Lagos State. A sample size of 44 respondents were drawn from the entire population using purposive sampling techniques. The instruments for data collection were a researcher's self-developed questionnaire titled Digitalization and Organizational Performance in Logistics Firms (DOPLF) and a researcher-structured interview. The research questions were answered using mean and standard deviation while the null hypotheses were tested at 0.05 level of significance using the t-test statistics. Findings revealed that respondents strongly agreed on how the adoption of digital transformation has changed the logistics businesses as well as on the extent to which digital technologies and connectivity impact organizational productivity. It was concluded that digitalization to a high extent impacts organization performance and has the capability to generate huge profits when ICT tools are successfully implemented. The study hence recommended the following amongst others that; logistics companies should embrace IT tools and services to gain a competitive advantage and improve service delivery to customers, have more self-service enabled services, and automate all critical processes to improve efficiency, reliability, and control in the organization.

ABSTRACT
The relationship between revenue and cost is established to find the intrinsic nature with integrated Cobb-Douglas function. It is found when the best labour is 98 the cost is low and the number of cars are 1.1 with the best profit intersection of 41 thousand Yuan which is best profit point with integrated method. When the best capital is 498Yuan the profit point is 1.1 of the number of cars with the 40 thousand Yuan too. The intersection of pieces and value between profit and cost attains 0.9 and 1.16 pieces with 32 and 41 thousand Yuan at the best capital and labor respectively. This is the important one in the course of profit. It is transferring the start and end point. Generally this point is regarded the best profit begins and may be chosen as the best profit. Meantime in the scope of PAA and PAC it has 0≤Aprofit≤AC, PAC and PAR it has AC≤Aprofit≤AR and ≥PAR it has Aprofit ≥AR. So the best profit has been accessed PAR the average profit is bigger than AR ie.Aprofit ≥AR. It is the last one mentioned above if manufacturer has enough investment capital and technique workers.The Cobb-Douglass Function has been a limited for example the the precision matter that makes the modeling a certain thing.
