Food Fortification

Introduction. The problem of micronutrient deficiency remains a relevant issue all over the world. However, it is mostly developed countries that practice food fortification. The FAO and the WHO accumulate related experience and summarize it in various documents. Yet some aspects of the problem can be solved on state level. The present research featured micronutrient deficit and preventive measures in several countries taking into account local food traditions. Since 1920, a number of industrially developed northern countries have started developing and implementing various food fortification programs. Similar programs are being introduced in East, Central, and South Africa and Southeast Asia. For 40 years, Russia has been taking various measures to prevent micronutrient deficiency and related diseases. Results and discussion. The research revealed the social and economic measures of food fortification that were found lacking in these countries. The main problem proved to be iodine, iron, and vitamin A deficiency. However, lack of other micronutrients also remains a burning issue. The present paper gives an overview of iodine, selenium, and iron deficiencies in several countries. The authors proposed several solutions, e.g. food group selection, food additives (mono or premix), various ways of fortification, etc. The article also contains a list of main Russian regulatory documents that control the production and turnover of food fortification. The authors showed advantages of food fortification of mass consumption products, e.g. the low cost of processing, the affordability of enriched products, their availability for different social population, the well-developed regulation standards, the good social effect of food fortification projects, their economic efficiency, etc. Taking into consideration the environmental changes and various geopolitical and economic factors that negatively affect nutrition and population health, the authors recommend to continue evidence-based research in this direction to develop new technologies and food supplements. Conclusion. The novelty of the research lies in the fact that it reveals priority areas for prospective scientific research in food fortification based on a thorough analysis of the existing experience. From the point of view of practical application, the research offers a deeper understanding of the problem, stresses its relevance, sets goals and objectives of future studies, and offers some ideas for preventive programs.

Vitamin A deficiency is still one of the major public health problems in least developed countries. Fortification of vegetable oils is a strategy implemented worldwide to prevent this deficiency. For a fortification program to be effective, regular monitoring is necessary to control food quality in the producing units. The reference methods for vitamin A quantification are expensive and time-consuming. A rapid method should be useful for regular assessment of vitamin A in the oil industry. A portable device was compared to high-performance liquid chromatography (HPLC) for three plant oils (rapeseed, groundnut, and soya). The device presented a good linearity from 3 to 30 mg retinol equivalents per kg (mg RE.kg- 1). Its limits of detection and quantification were 3 mg RE.kg- 1 for groundnut and rapeseed oils and 4 mg RE.kg- 1 for soya oil. The intra-assay precision ranged from 1.48 % to 3.98 %, considered satisfactory. Accuracy estimated by the root mean squares error ranged from 3.99 to 5.49 and revealed a lower precision than HPLC (0.4 to 2.25). Although it offers less precision than HPLC, the device estimates quickly the vitamin A content of the tested oils from 3 or 4 to 15 mg RE.kg- 1.

Hospital Conversions

The pressures encountered by hospitals in the current era of reimbursement declines and stiffened competition are well known. As the “ultimate” payors—primarily employers and government—aggressively continue to seek low cost care, the response of the hospital industry has been to move toward consolidation and efficiency-enhancing mechanisms.Increasingly, nonprofit, tax-exempt hospitals have come to believe that they are at a significant disadvantage vis-á-vis their for-profit brethren in their ability to attract the capital needed to compete in the market. A growing trend among nonprofit hospitals, therefore, is to sell to or enter into a joint venture with a proprietary organization, or alternatively to convert to for-profit status. In 1995, fifty-eight nonprofit hospitals became for-profit; hospital conversions to for-profit status in 1996 are projected to outstrip the pace established the prior year.The conversion trend has not gone unnoticed at the state level. Recently, several states have proposed or enacted laws regulating sales and conversions of nonprofit hospitals, and many more states are contemplating such legislation.

University campuses are normally constituted of large buildings responsible for high energy demand, and are also important as demonstration sites for new technologies and systems. This paper presents the results of achieving energy sustainability in a testbed composed of a set of four buildings that constitute the Telecommunications Engineering School of the Universidad Politécnica de Madrid. In the paper, after characterizing the consumption of university buildings for a complete year, different options to achieve more sustainable use of energy are presented, considering the integration of renewable generation sources, namely photovoltaic generation, and monitoring and controlling electricity demand. To ensure the implementation of the desired monitoring and control, an internet of things (IoT) platform based on wireless sensor network (WSN) infrastructure was designed and installed. Such a platform supports a smart system to control the heating, ventilation, and air conditioning (HVAC) and lighting systems in buildings. Furthermore, the paper presents the developed IoT-based platform, as well as the implemented services. As a result, the paper illustrates how providing old existing buildings with the appropriate technology can contribute to the objective of transforming such buildings into nearly zero-energy buildings (nZEB) at a low cost.

Civil wars produce immense humanitarian crises, causing millions of individuals to seek refuge in other countries. The rate of disease prevalence has inclined among the refugees, increasing the cost of healthcare. Complex medical conditions and high numbers of patients at healthcare centers overwhelm the healthcare system and delay diagnosis and treatment. Point-of-care (PoC) testing can provide efficient solutions to high equipment cost, late diagnosis, and low accessibility of healthcare services. However, the development of PoC devices in developing countries is challenged by several barriers. Such PoC devices may not be adopted due to prejudices about new technologies and the need for special training to use some of these devices. Here, we investigated the concerns of end users regarding PoC devices by surveying healthcare workers and doctors. The tendency to adopt PoC device changes is based on demographic factors such as work sector, education, and technology experience. The most apparent concern about PoC devices was issues regarding low accuracy, according to the surveyed clinicians.

PurposeHealthcare employs informatics to offer its services through information technology where the social network can aid virtual medical learning. Since the usage of the internet and other electronic tools for medical services delivery is at the initial stage, it is essential to examine the factors that condition patients and medical elements in a virtual environment can develop relationship models on the health services. So, the authors have systematically reviewed virtual medical learning and offered some suggestions for the upcoming works. The authors have also discovered gaps in the state-of-the-art papers and provided solutions for them.Design/methodology/approachNumerous novel advancements have changed the old exercise of therapeutic and analytic learning. Virtual spaces have quickly turned into a section of the learning technology vision. Given the importance of its achievements and endless low-cost expansion of the educational system, virtual education has been considered as one of the issues raised by the information communities. Medicine and health are some of the most important fields in virtual technologies. Hence, in this paper, we have used a systematic literature review to deeply examine virtual medical learning. After establishing exclusion and inclusion criteria, an independent systematic search in Google Scholar, ACM, Scopus, Eric, Science Direct, Springer link, Emerald, Global ProQuest and IEEE for relevant studies have been performed, and 21 papers have been analyzed. Detailed data have been mined out of the papers.FindingsThe authors have found that virtual medical learning improves and expands the knowledge core and meaningfully affects the exercise. Virtual learning (VL) has been used in many therapeutic zones, like therapeutic learning, surgery, diagnosing, combining and regularizing processes. It has presented a fundamental access point and a referral mechanism for all of a course's component communities. It can also simplify communicative education, allowing learners to get abilities before applying them in a real-world situation. Also, the communicative characteristics of different VL programs can somehow be like direct teaching.Research limitations/implicationsSome excellent work may be removed owing to applying the filters to select the primary papers. Surveying all the documents on the topic of virtual medical learning is impossible, too. Nevertheless, the authors have tried to present a perfect survey of virtual medical learning. The results will be helpful for scholars to propose better virtual medical learning techniques.Practical implicationsE-learning has become an indispensable additional learning tool in medical education. The introduction of new learning technologies, the exponential growth of Internet usage and the advent of the World Wide Web can change the face of higher education. The results will be helpful for scholars for the upcoming works. The application of a literature review of partial least squares theory was useful for offering comprehensive literary coverage and completing the knowledge development analysis. The authors have backed scholars and experts for better understanding the development of virtual medical learning systems via presenting comparative data and scrutinizing the present advances.Originality/valueThe paper enhances intellectual knowledge by improving the conception of virtual medical learning. It informs the development, use of virtual medical learning and the upcoming works. The lack of comprehensive papers in this field has increased the importance of this paper. The present paper can handle the pace of publications.

In search of an efficient but simple, low cost procedure for the serodiagnosis of Toxoplasmosis, especially suited for routine laboratories facing technical and budget limitations as in less developed countries, the diagnostic capability of Hematoxo® , an hemagglutination test for toxoplasmosis, was evaluated in relation to a battery of tests including IgG- and IgM-immunofluorescence tests, hemagglutination and an IgM-capture enzymatic assay. Detecting a little as 5 I.U. of IgG antitoxoplasma antibodies, Hematoxo® showed a straight agreement as to reactivity and non-reactivity for the 443 non-reactive and the 387 reactive serum samples, included in this study. In 23 cases presenting a serological pattern of acute toxoplasmosis and showing IgM antibodies, Hematoxo® could detect IgM antibodies in 18, indicated by negativation or a significant decrease in titers as a result of treating samples with 2-mercapto-ethanol. However, a neat increase in sensitivity for IgM specific antibodies could be achieved by previously removing IgG from the sample, as demonstrated in a series of acute toxoplasmosis sera. A simple procedure was developed for this purpose, by reconstituting a lyophilized suspension of Protein A - rich Staphylococcus with the lowest serum dilution to be tested. Of low cost and easy to perform, Hematoxo® affords not only a practical qualitative procedure for screening reactors and non-reactors, as in prenatal services, but also quantitative assays that permit to titrate antibodies as well as to identify IgM antibodies.

Abstract. Mobile-Geographic Information System (GIS) is one of the dimensions of these enhancements, which, due to its flexibility, its simplicity with traditional GIS systems, the need for less expertise and low cost, has brought this technology into a variety of areas. Mobile technologies using mobile devices is proving to be a more effective implementation for crime detection and monitoring. Mobile-GIS are operating within a wider range of GIS technologies, wireless technologies, and global positioning technology. The ability to use this system to report crime and control crime in cities has led different countries to use this system for easier and less costly reporting of citizens, and many developed countries use Mobile-GIS technology to do this. And they use this technology depending on their needs. In this research, Mobile-GIS applications in the five developed countries of the world are being studied and their disadvantages and advantages are discussed, and finally, regarding to society safety the possibilities and necessity of police department to develop such programs are discussed. In this study, we are proposing a crime reporting and management model using GIS technologies and review the all possibility and limitation to implementation are confronted in order to mitigate the challenges are faced by most developing countries in reducing the crime rates. A conceptual plan for constructing such a program in the police department has been proposed, which is suggested by using systems like Real-time kinematic (RTK) to improve the user's location to increase accuracy.

This study aims at identifying the challenges of digitalization and artificial intelligence for modern economies, societies and business administration. The implementation of digitalization schemes as Industry 4.0 are presently official policy of many developed countries. The goal is optimization of production processes and supply chains. Artificial intelligence is also affecting many fields. Both technologies are expected to substantially change working conditions for many people. It is important to identify the kind and impact of these changes and possible means to minimize negative effects. For this purpose, this study uses previous results about the disappearance of manufacturing jobs in the USA and their impact on different groups of society together with technical information about the new technologies to deduce expected changes caused by digitalization and artificial intelligence. Results are that both technologies will destroy large numbers of jobs and complete job classes while at the same time creating new jobs very different from the ones destroyed. Extensive permanent education and re-education of employees will be necessary to minimize negative effects, probably even changes to a more broad-based education to improve the potential of job changes into completely new fields. In addition, the technical information about digitalization in cyber-physical systems points to dangers that will require solutions on the international level.
