The Moment

For today, computer networks are an integral part of our daily lives. As the analysis shows, the network is ex-tremely vulnerable, it can serve as a place of information leakage, changes of configuration of settings and modification of data by the attackers. There are many more threats, and the security of the network requires a great deal of attention to ensure the security of the network in order to maintain the confidentiality and integrity of the data. Organizations must regularly assess the vulnerability of the entire network to test the security level and strengthen the network. We use vulnerability scanners to find weaknesses, which are useful for detecting security vulnerabilities on a case-by-case basis and across the network as a whole. The purpose of the work is to explore the computer network for vulnerabilities using the Nessus Professional scanner. Research Methods – network scanning by Nessus Professional vulnerability scanner. The Nessus Professional vulnerability scanner from Tenable Network Security, which is freely available, was used for the research. The Nessus Professional scanner has been found to have better functionality and performance than other available scanners. The only downside to the scanner is its cost per year, as well as scanning a large number of hosts on the network at a time (over 100 hosts). After the scanner was successfully installed, carried out it was in-spected from the moment it was launched to the generation of host test reports. For the work, the Lviv State University of Life Safety network was tested. In the post-scan report, which is displayed in HTML format, you can see scan details for each host; the number and nature of vulnerabilities; the error correction dashboard. According to the results of testing, vulnerabilities of low, medium and high levels of hazards were identified, totaling 376. Vulnerabilities were ana-lyzed based on the obtained results, namely: a brief description and a way to solve the problem.

Improve Instruction

The Materials Science Department at Iowa State University has developed a laboratory designed to improve instruction in the use of the scanning electron microscope (SEM). The laboratory makes use of a computer network and a series of remote workstations in a classroom setting to provide students with increased hands-on access to the SEM. The laboratory has also been equipped such that distance learning via the internet can be achieved.A view of the laboratory is shown in Figure 1. The laboratory consists of a JEOL 6100 SEM, a Macintosh Quadra computer that acts as a server for the network and controls the energy dispersive spectrometer (EDS), four Macintosh computers that act as remote workstations, and a fifth Macintosh that acts as an internet server. A schematic layout of the classroom is shown in Figure 2. The workstations are connected directly to the SEM to allow joystick and computer control of the microscope. An ethernet connection between the Quadra and the workstations allows students seated there to operate the EDS. Control of the microscope and joystick is passed between the workstations by a switch-box assembly that resides at the microscope console. When the switch-box assembly is activated a direct serial line is established between the specified workstation and the microscope via the SEM’s RS-232.

Positive And Negative Symptoms

Background: Schizophreniais a chronic and debilitating illness that affects approximately one percent of the population. The symptoms of schizophrenia are typically thought of in separate domains, including positive symptoms (hallucinations and delusions), negative symptoms (diminished emotional expression and amotivation), and cognitive deficits. Importantly, the negative symptoms have been consistently found to adversely influence functional outcomes, in particular due to markedamotivation.^1 There have been suggestions that these individuals also experience deficits in the experience of pleasure, especially in their capacity to anticipate pleasure.^2 However, such investigations have not included the examination of these symptoms in those in the prodromal phase ofthis illness, a time that holds promise for early intervention and altering thecourse of schizophrenia.^3 Methods: In an effort to examine deficits in motivation and pleasure in the prodromal phase of schizophrenia, we have used an experience sampling method to assess “in the moment” motivation and pleasure in individuals at high risk of developing schizophrenia and healthy controls. Subjects completed baseline assessments including evaluation of their positive and negative symptoms. Subsequently, through the use of a personal digital assistant, subjects rated their motivation and experience of consummatory and anticipatory pleasure in their daily lives, multiple times over the course of four days. Results and Conclusions: Preliminary data will be presented, as well as the importance of these findings in the context of understanding the underlying pathobiology of this illness, and guiding our search for effective treatments to improvefunctional outcomes in schizophrenia.

Aim: The current COVID-19 pandemic has been causing significant upheavals in the daily lives of citizens and consequently also their mood (stress, distraction, anxiety, etc.), especially during the lockdown phase. The aim of the investigation is to evaluate the benefits of 20–30 minutes in contact with nature. Background: The Scientific Community, also through the evidence-based design approach, has already demonstrated the importance of greenery and nature on the psychophysical well-being of people and, in a moment of emergency, contact with the nature can be therapeutic and quite influential on the mental health of staff subject to stress. Method: During the lockdown, an Italian multidisciplinary working group promoted an experience-based survey, based on the Profile of Mood States methodology, for measuring the psychophysical well-being of hospital staff. Results: The author collected 77 questionnaires. The benefits that users have obtained from the experience in nature have been investigated by comparing the type of stresses they were subjected to and highlighting various peculiarities in the data analysis associated with the type of green in which they carried out the survey, the healthcare areas in which they worked during the pandemic emergency, and the moment in which the survey was conducted. Conclusions: The study has highlighted that a short break in green spaces strongly influenced the mental and psychophysical well-being of hospital staff, emphasizing the importance of nearby green spaces in architectures for health. Even a brief break in nature can regenerate users, especially in times of a stressful health emergency.

Advent of technology has caused growing interest in using computers to convert conventional paper and pencil-based testing (Henceforth PPT) into Computer-based testing (Henceforth CBT) in the field of education during last decades. This constant promulgation of computers to reshape the conventional tests into computerized format permeated the language assessment field in recent years. But, enjoying advantages of computers in language assessment raise the concerns of the effects that computerized mode of testing may have on CBT performance. Thus, this study investigated the score comparability of Vocabulary in Use test taken by 30 Iranian undergraduate students studying at a state university located in Chabahar region of Iran (CMU) to see whether scores from two administrations of testing mode were different. Therefore, two similar tests were administered to the male and female participants on two testing mode occasions with four weeks interval. Employing One-Way ANOVA statistical test to compare the mean scores and Pearson Correlation test to find the relationship between mode preference and performance revealed that two sets of scores were not different and gender difference was not also considered a variable that might affect performance on CBT. Based on the results, computerized version of the test can be considered a favorable alternative for the state undergraduate students in Iran.
