This paper describes the developed technology for using the Raspberry Pi micro-computer to teach practical skills on computer networks and operating systems. The effectiveness of acquiring skills using the proposed technology is due to the fact that it allows organizing the workshops with personal support with the necessary special tools. The paper presents a largely implemented project on an initiative basis, preceding the work on commercialization of the described results. In the present work a full detailed content of the steps for implementation and subsequent commercialization of the solutions presented in the project is given. There was assembled a prototype of the hardware-software device. There were developed individual training kits for distribution to students in the classroom. To study the disciplines “Computer Networks” and “Operating Systems”, methodological recommendations on the operation and maintenance of the described computer class were prepared; a methodological manual is being prepared for studying these disciplines using these training kits; the guidelines for operation of devices and components were developed. The work also prepared boot files with the predefined working environment for each discipline. These files include the needed operating systems, the needed preinstalled software, a customized user interface, the needed literature, a training manual, and methodological recommendations. In terms of commercialization, the calculations were carried out on the costs of organizing a computer class based on the Raspberry Pi: implementation of the developed technology; the effectiveness of its implementation was evaluated. A commercial plan was drawn up and calculations were made on the current date with the reference mainly to Kazakhstan; the trial design and layout of the packaging case, information stickers and cover (as well as layout) of the training manual were completed; industrial designs were developed in order to prepare the project for commercialization. The results are practically significant, when they were received, widespread methodology and development tools were used, they can be universally used, including in the field of education without any restrictions.

Computer networks are basically not safe to access freely. Security gaps in the network can be seen by irresponsible people with various techniques. Opening a port for access carries a high risk of being attacked by an attacker. In this connection, network administrators are required to work more to be able to secure the computer network they manage. One form of network security that is often used by network administrators in server management is through remote login such as ports on telnet, SSH, etc. A port that is always open is a network security hole that can be used by people who are not responsible for logging into the server. Focusing on these problems, in this study, Random Port Knocking is the right way and can be used to increase network security. With Random Port Knocking, the port will be opened as needed, the port will automatically change when it fails to log in more than three times and IP will automatically be blocked and access will not continue so that attacks on the network can be avoided and network security stability can be further improved. The final result of this research shows that the method applied in this research makes server safe. Because port randomization and IP block make irresponsible parties try harder to penetrate firewall walls.

Process Diagrams

A management of computer classroom is undoubtedly a difficult task for the administrator which has to prepare virtual operating systems for education. It is quite common that lectors need to edit the particular machine during the semester, and that is the case where the main problems can appear. The process of changes deployment is not just very time-consuming but during it a virtual machine inconsistency can appear. The main part of this paper focuses on system process diagrams and its pseudocode. At first, the machine is created on the remote server by lector or administrator. After a proper approval, the machine is able to be deployed. The lector then specifies the details about date, time and destinations of the virtual machine deployment. Once these details are approved, the virtual machine will be automatically deployed at the specified time. The automatic deployment includes also an initial configuration of the virtual machine at remote desktop and its post-install configuration (hostname, MAC address, etc.). Once all steps are completed, the process will be marked as succeed. We present an automatized solution which provides a possibility how to easily manage computer classroom with virtual operating systems. The proposed solution should deliver a greater flexibility, more reliability and faster deployment in comparison with the current solution used in our computer classroom. The proposal is also able to manipulate with already deployed machines for easy changes (e.g. software updates). The main advantage is the improvement of classroom management process automation.

Population of rural areas face distinct health challenges due to economic conditions, cultural/behavioural factors, and health provider shortages that combine to impose striking disparities in health outcomes among them. The process of recruitment takes about four to six months for Recruitment of Medical officers and paramedics. The number of applicants is quite limited because of dearth of doctors and paramedics in the State. It was felt that the health staffs incentives will help to increase the turnover of health staffs to some extent in the rural and remote areas. Monitoring cell has been constituted at the state level. The trainings are being monitored at regular intervals of time. The motivational level of health staff at all levels seems to be low. Continuous communication and feedback by state level programme officers is needed on regular basis. Placement of the suitable trained personnel is needed at those health facilities where sufficient infrastructure is available. Since 2010-11, there has been a continuous focus on the capacity building of the existing manpower in  the  state.  Trainings  as  per  GOI  guidelines  on  Immunization,  IMNCI,  EmOC,  LSAS,  SBA  and Minilap/MVA etc. have been taken up with full strength. In addition, the State wide training on immunization for Medical Officers, IPC skills for breast feeding and basic training in neonatal resuscitation also has been taken up at various levels. More than four-fifth of the total staffs in the health facilities were agreed on all the educational interventions for retention of health staffs in rural areas. For the regulatory interventions such as enhanced scope of practice, different types of health workers; multi skilling of alternate service providers, compulsory rural service which may be mandatory for obtaining license to practice or can be a prerequisite for entry into specialization and subsidized education in return of assured services were agreed by four-fifth of the total staffs. For the interventions related to professional and personal support such as better living conditions (water, sanitation, electricity, telecommunications, schools, etc.), safe and supportive working environment, outreach activities to facilitate cooperation between health workforce from better served and underserved areas; use of tele-health, designing career development programmes linked with rural service: more senior posts in rural areas and professional networks for rural areas such as rural health professional associations, rural health journals, etc. about 88 percent of the HR categories of Staffs were agreed in the health facilities

The Maker Movement

Purpose This paper aims to propose a maker’s approach to teaching an operating systems (OSs) course in which students apply knowledge of OSs to making a toy robot by focusing on input/outputs, hardware devices and system programming. Design/methodology/approach Classroom action research is involved in this study. Findings After the course was taught in this maker’s approach in two consecutive school years, some observations were reported. Students were enthusiastic in doing a series of assignments leading to the completion of a toy robot that follows a black line on the ground. In addition to enjoying the learning process by making tangible products, the students were excited to be able to demonstrate the skills and knowledge they learned with the robots they made. Research limitations/implications The research results were based mainly on the instructor’s observations during the lectures and labs. Practical implications Lessons from this study can inspire other instructors to turn traditional engineering courses into maker courses to attract students who enjoy making. Industry should welcome engineering graduates to join the companies with more hands-on experiences they have gained from maker courses. Social implications Although the maker movement has attracted much attention in K12 education, there is little research that studies how this maker spirit can be incorporated in traditional engineering courses that focus mainly on theories or software. Originality/value Including electronics and mechanical components in programming assignments would bring surprising effects on students’ motivation in learning.
