Lessons Learned from Missing Flooding Barriers Operating Experience
Authors: Šimić Zdenko , Peinador Veira Miguel
Published: June 2022

Flooding hazard is highly significant for nuclear power plant safety because of its potential for common cause impact on safety related systems, and because operating experience reviews regularly identify flooding as a cause of concern. Source of the flooding could be external (location) or internal (plant design). The amount of flooding water could vary but even small amount might suffice to affect redundant trains of safety related systems for power supply and cooling. The protection from the flooding is related to the design-basis flood level (DBFL) and it consists of three elements: structural, organizational and accessibility. Determination of the DBFL is critical, as Fukushima Daiichi accident terribly proved. However, as the topic of flooding is very broad, the scope of this paper is focused only on the issues related to the missing flood barriers. Structural measures are physically preventing flooding water to reach or damage safety related system, and they could be permanent or temporary. For temporary measures it is important to have necessary material, equipment and organizational capacity for the timely implementation. Maintenance is important for permanent protection and periodical review is important for assuring readiness and feasibility of temporary flooding protection. Final flooding protection element is assured accessibility to safety related systems during the flooding. Appropriate flooding protection is based on the right implementation of design requirements, proper maintenance and periodic reviews. Operating experience is constantly proving how numerous water sources and systems interactions make flooding protection challenging. This paper is presenting recent related operating experience feedback involving equipment, procedures and analysis. Most frequent deficiencies are: inadequate, degraded or missing seals that would allow floodwaters into safety related spaces. Procedures are inadequate typically because they underestimate necessary time or they do not provide sufficient instructions. Most of the events are related to deficiencies discovered during walk-down, review, maintenance and sometimes to incidents. Perhaps these lessons learned from recent events could help filling the missing gap to have most complete flooding protection. This paper presents results from the most recent activity related to the operational experience feedback for the nuclear power plant safety in the EC JRC Clearinghouse

Published: June 2022

The Slovenian Krško Nuclear Power Plant (NEK) model was built in using APROS - Advanced PROcess Simulation environment. The basis for the this model was the RELAP5/MOD3.3 Engineering Handbook, the model was updated to the 26th cycle and also includes the upflow conversion modification. A detailed model nodalisation was created for each system and every system was separately validated. The current model covers the primary circuit with the core kinetics model, the secondary circuit and their control systems. The steady state of the APROS NEK model already having been validated, the plan now is to validate the model for some transients and design basis accidents. In this article the plant behaviour after the manual reactor trip is analysed in detail. Two scenarios of the manual reactor trip transient are performed, where either the Main Steam Isolation Valve (MSIV) closes after 60s – case A, or remains open – case B. After the manual reactor trip from the 100% power, the control system signal actuations and their times were followed and then the responses of different affected systems were being observed. All those recorded values were then compared with the identical transient performed on the similar NEK model with the RELAP5/MOD3.3 system code. This procedure allowed to bring the current APROS NEK model one step forward towards being assured to have accurate calculations.

Authors: Vuković Igor , Prosen Rudolf
Published: June 2022

The nuclear accident in Japanese plants in 2011 has initiated a quick response from the countries utilizing a nuclear power. Krsko Nuclear Power Plant (NEK) was required by Slovenian Nuclear Safety Administration (SNSA) to perform consequential actions to reduce the risk of severe accidents and their consequences as low as feasible. NEK have analyzed the response to the severe accidents, and based on the results of this analysis, proposed the measures to be implemented in the shortest possible time. In response to SNSA request NEK has developed the Safety Upgrade Program (SUP) which contains a comprehensive set of measures for plant safety improvements. SUP Phase 1 has been implemented during the Outage 2013. This paper presents the work done on the evaluation of impact of plant modifications planned for implementation in Phases 2 and 3 of NEK Safety Upgrade Program on the quantitative figure of merit for the plant risk significance – total core damage frequency (CDF). A significance of the most valuable measures in terms of contribution to the CDF reduction was determined and a new fractional contribution of initiators categories was obtained. The quantification of total CDF was made by employment of RiskSpectrum PSA code and running a predefined set of analytical cases for all initiator categories covered by the scope of NEK PSA model. The basis for analysis was NEK’s most recent at-power PSA model which reflects the plant status with plant modernization implemented in SUP Phase 1. The analysis was done in two steps. In the first step plant modifications planned for SUP Phase 2 were addressed and in the second step plant modernization measures and upgrades planned in SUP Phase 3 were modeled in addition to those already modelled in the first step.

Authors: Bilgin Nazmiye Gönul
Published: June 2022

In this study, Neutrophic normed spaces, which is one of the popular mathematics topics of recent times, is discussed. The Neutrosophic approach, which argues that it is insufficient to evaluate the problems in daily life as just right and wrong, is based on the principle that the degree of indecision should be taken into account. Now, rough statistical convergence of triple sequences is defined in Neutrosophic normed spaces. Moreover, the important topological properties about to the set of cluster points of roughly statistical convergent triple sequences are given.

Tujuan penelitian ini adalah untuk mengetahui peran wanita laboratorium remo Surabaya (LRS) dalam pelestarian budaya tari remo di masa pandemic covid-19. Tari Remo merupakan tari selamat datang khas Jawa Timur yang dikemas sebagai gambaran keberanian seorang pangeran yang berjuang dalam pertempuran. Biasanya di Surabaya, budaya kesenian tari remo dilestarikan melalui latihan menari di sanggar budaya setiap hari dan festival seni Cak Durasim setiap tahunnya. Namun ketika pandemi covid-19 melanda, kegiatan menari pun berhenti sehingga menghambat upaya pelestarian budaya tari remo di Surabaya. Metode penelitian ini menggunakan kualitatif deskriptif. Teknik pengumpulan data dengan wawancara mendalam, observasi dan data sekunder. Hasil penelitian menunjukkan bahwa peran wanita LRS dalam pelestarian budaya tari remo di masa pandemic covid-19 terbagi menjadi tiga peran. Pertama peran kordinator, yaitu ibu Dini selaku pimpinan sanggar LRS mengkordinir para penari wanita agar tetap berlatih untuk meningkatkan imun tubuh yangmana terbagi menjadi kelompok-kelompok. Kelompok tersebut terbagi berdasarkan hari latihan, tempat dan rentang usia. Kedua peran fasilitator, yaitu Ibu Dini memfasilitasi tempat latihan selama pandemic covid-19 sesuai protocol kesehatan di BG Juntion. Ketiga, peran promotor yaitu para pelatih dan penari wanita LRS membujuk lembaga sosial untuk memberikan ruang pentas. Selain itu mempromosikan tarian secara virtual dalam pentas Hari Tari Dunia, world day dancing challenge dan lomba tari kreasi. Dengan begitu dapat mengingat bahwa tari remo masih eksis meskipun di masa pandemic. Dengan demikian peran penari wanita LRS dalam pelestarian budaya tari remo di masa pandemi Covid-19 cukup berperan banyak namun masih ada kendala yaitu kehandalan sumber daya dalam menggunakan teknologi informasi

Authors: Oktaria Grahani Firsty , Mardiyanti Ressy , Permei Sela Nina , Nuriyah Sinta
Published: June 2022

Abstrak. Psychological well being (PWB) sebagai pencapaian penuh dari potensi psikologis seseorang dan suatu keadaan ketika individu dapat menerima kekuatan dan kelemahan diri apa adanya, memiliki tujuan hidup, mengembangkan relasi yang positif dengan orang lain, menjadi pribadi yang mandiri, mampu mengendalikan lingkungan, dan terus bertumbuh secara personal (Ryff, 1995). Seseorang yang menilai lingkungan kerja sebagai lingkungan yang menarik, menyenangkan, dan penuh dengan tantangan, maka ia akan merasa bahagia dan menunjukkan kinerja yang optimal (Wright & Bonnet, 2007). Lockwood (2003) menambahkan bahwa work family balance (WFB) adalah suatu keadaan seimbang pada dua tuntutan dimana pekerjaan dan kehidupan seorang individu adalah sama. Wanita yang bekerja merupakan hal yang sudah biasa pada saat ini. Pada tahun 2000, tiga per lima wanita bekerja dan pada usia 25 sampai dengan 44 tahun sebanyak 75% wanita bekerja, 60% wanita bekerja dan memiliki anak di bawah usia 12 tahun, dan wanita yang akan bekerja di luar rumah selama kehidupan dewasa adalah 90% (Betz dalam Utami, 2011). Penelitian ini bertujuan untuk mengetahui pengaruh psychological well being terhadap work family balance pada perempuan bekerja dan untuk memperoleh gambaran dinamika pengaruh psychological well being terhadap work family balance pada perempuan bekerja. Pendekatan yang digunakan dalam penelitian ini adalah pendekatan kuantitatif. Data dikumpulkan dengan menggunakan alat ukur berupa skala psychological well being (PWB) dan skala work family balance (WFB). Sampel yang digunakan adalah perempuan usia produktif dan bekerja dengan rentang usia 17-60 tahun. Teknik sampling yang digunakan adalah purposive sampling. Data analisis secara statistik dengan menggunakan analisis regresi sederhana.

Authors: Artisa Rike Anggun , Dewi Reni Novika
Published: June 2022

Perbedaan gender telah melahirkan perbedaan peran, sifat dan fungsi sebagai hasil dari konstruksi sosial-budaya. Hal tersebut turut mempengaruhi penentuan kepesertaan KB keluarga dimana tertanam stereotypebahwa KB identik dengan urusan perempuan. Implikasinya adalah tingginya ketimpangan gender dalam kepesertaan KB. Namun kasus yang terjadi di Kecamatan Pakenjeng Kabupaten Garut menunjukan adanya kondisi “anomali” dimana kepesertaan KB pria sangat tinggi. Tujuan dari penelitian ini adalah untuk memahami fenomena kepesertaan KB pria yang dilihat dari perspektif dekonstruksi gender. Metode yang digunakan dalam penelitian ini adalah metode kualitatif dengan pendekatan studi kasus. Hasil penelitian menunjukan bahwa fenomena tingginya kepesertaan KB pria didukung oleh proses dekonstruksi peran gender yang dilakukan melalui upaya pemberian informasi dan penyediaan pelayanan KB. Dekonstruksi peran gender ini dapat mendorong upaya mewujudkan kesetaraan gender dalam program KB.

Authors: Rankoana Sejabaledi Agnes
Published: June 2022

The purpose of this research was to describe the socio-economic elements that influence small-scale farming in South Africa’s Limpopo Province. The research used a qualitative method and randomly chose 100 farmers in the Sekhukhune District Municipality of Limpopo Province. A structured questionnaire was used to conduct the interviews. The generated data were analyzed using descriptive statistics. The research found that indigenous crop production was largely determined by six socioeconomic variables: age, gender, marital status, educational attainment, income, and employment. Crops were grown to provide grains, vegetables, and fruits for household consumption. Indigenous crop farming can provide all community members with food security. The research concluded that adverse climate change has effects on food security, and socio-economic aspects might be taken into account in the creation of food security adaptation techniques.

Keywords: Small-scale farming, crop production, socio-economic factors, food security, cultural heritage
From Twistor-Particle Models to Massive Amplitudes
Authors:   University of Oxford, UK, Albonico Giulia , Geyer Yvonne ,   Chulalongkorn University, Thailand, Mason Lionel ,   University of Oxford, UK
Published: June 2022

In his twistor-particle programme of the 1970's, Roger Penrose introduced a representation of the massive particle phase space in terms of a pair of twistors subject to an internal symmetry group. Here we use this representation to introduce a chiral string whose target is a complexification of this space, extended so as to incorporate supersymmetry. We show that the gauge anomalies associated to the internal symmetry group vanish only for maximal supersymmetry, and that correlators in these string models describe amplitudes involving massive particles with manifest supersymmetry. The models and amplitude formulae exhibit a double copy structure from gauge theory on the Coulomb branch to gravity, although the graviton remains massless. The formulae are closely related to those obtained earlier by the authors expressed in terms of the polarised scattering equations.

La place du financeur dans l’essor de l’AFEST
Authors: Carrier Mathieu
Published: June 2022

L’AFEST interroge l’action des financeurs publics et parapublics, qui doivent non seulement intégrer cette nouvelle modalité dans leurs processus de gestion, mais également la promouvoir pour répondre à la volonté du législateur. Ils sont ainsi invités à se ré-inventer, en assurant un rôle d’influenceur de l’action des entreprises et des particuliers dans le respect du cadre défini par l’action publique. On peut aller jusqu’à imaginer que le financeur n’aura bientôt plus qu’une place réduite au sein de l’AFEST, lorsque les entreprises s’en seront approprié les mécanismes et en auront identifié les bénéfices, au point qu’il ne sera plus nécessaire de prévoir une incitation financière pour les encourager à initier de telles actions.

Certaines modalités d’accompagnement – axées sur la maîtrise des situations de gestion – s’approchent des pratiques développées dans le cadre des AFEST. Une enquête auprès de réseaux d’accompagnement montre que ces apprentissages situationnels pourraient intervenir, en réalité, tout au long du parcours, à partir de situations de gestion réelles, émergentes, ou de situations construites. La référence AFEST permet d’imaginer un cadre global et stratégique d’accompagnement de et par l’expérience des créateurs, susceptible de renforcer son efficacité en termes de développement des compétences entrepreneuriales.
Stability and dynamics of spike-type solutions to delayed Gierer-Meinhardt equations
Authors: Khalil Nancy , Iron David , Kolokolnikov Theodore
Published: June 2022

For a specific set of parameters, we analyze the stability of a one-spike equilibrium solution to the one-dimensional Gierer-Meinhardt reaction-diffusion model with delay in the components of the reaction-kinetics terms. Assuming slow activator diffusivity, we consider instabilities due to Hopf bifurcation in both the spike position and the spike profile for increasing values of the time-delay parameter \begin{document}$ T $\end{document}. Using method of matched asymptotic expansions it is shown that the model can be reduced to a system of ordinary differential equations representing the position of the slowly evolving spike solution. The reduced evolution equations for the one-spike solution undergoes a Hopf bifurcation in the spike position in two cases: when the negative feedback of the activator equation is delayed, and when delay is in both the negative feedback of the activator equation and the non-linear production term of the inhibitor equation. Instabilities in the spike profile are also considered, and it is shown that the spike solution is unstable as \begin{document}$ T $\end{document} is increased beyond a critical Hopf bifurcation value \begin{document}$ T_H $\end{document}, and this occurs for the same cases as in the spike position analysis. In all cases, the instability in the profile is triggered before the positional instability. If however the degradation of activator is delayed, we find stable positional oscillations can occur in this system.
Cauchy problem for a fractional anisotropic parabolic equation in anisotropic Hölder spaces
Authors: Degtyarev Sergey
Published: June 2022

We consider a Cauchy problem for a fractional anisotropic parabolic equation in anisotropic Hölder spaces. The equation generalizes the heat equation to the case of fractional power of the Laplace operator and the power of this operator can be different with respect to different groups of space variables. The time derivative can be either fractional Caputo - Jrbashyan derivative or usual derivative. Under some necessary conditions on the order of the time derivative we show that the operator of the whole problem is an isomorphism of appropriate anisotropic Hölder spaces. Under some another conditions we prove unique solvability of the Cauchy problem in the same spaces.
Surveillance study of bloodstream infections, antimicrobial use, and resistance patterns among intensive care unit patients
Authors: Ababneh Mera A. , Al Domi Mohammad , Rababa’h Abeer M
Published: June 2022

Background:

Bloodstream infections (BSIs) are one of the most critical illnesses requiring intensive care unit (ICU) admission. This study assessed patterns of antimicrobial use and resistance in ICU patients with BSIs.

Methods:

Inpatients admitted to the ICU and who received at least one antimicrobial agent between January 1, 2017, and December 31, 2019, were included in the study. Electronic patients’ medical records were used to collect patients’ demographic, clinical, and microbiological data.

Results:

A total of 1051 patients were enrolled in the study, where 650 patients (61.84%) were treated with three or more antimicrobial agents. The most frequently used antimicrobials were piperacillin/tazobactam followed by teicoplanin, meropenem, and levofloxacin. The most predominant multidrug-resistant pathogens were Acinetobacter baumannii, followed by Escherichia coli, Methicillin-resistant Staphylococcus aureus (MRSA), Klebsiella pneumonia, and Pseudomonas aeruginosa.

Conclusions:

The administration of the antimicrobials among ICU patients was highly based on a combination of three or more broad-spectrum agents. MDR pathogens were found to be highly prevalent among ICU patients with BSI. Therefore, we suggest recommending that hospital policies should apply the antimicrobial stewardship protocols, infection control, and implement antimicrobial de-escalation protocol to reduce the harm pressure of antimicrobial resistance.
Correlations Between Proposed Orthoepic Competence Descriptors and Japanese Language Ability
Authors: Ito Hideaki
Published: June 2022

In this paper, three types of Japanese online tests, and self-assessment questionnaires comprised of 13 descriptor categories, including one category on Japanese orthoepic competence, were issued to 15 Japanese language learners attending language schools in Japan. As a result, we confirmed a more than moderate positive correlation between the orthoepic competence descriptors and test scores, both concerning the individual scores on the three tests and the aggregate total of those scores.  Based on these test results, learners were categorized into different skill levels, such as novice, intermediate, and advanced. Learners who scored at the intermediate level with their grammar test or scored over 170 total points across all tests tended to evaluate themselves at a B-level or higher competency level.

There is a growing concerns over the health risk of consuming seafood contaminated with poisonous metals from human activities.  This study examined the concentration and human health risk of Pb, Cd, Cr, Ni, Co, Zn, V and Hg associated with the consumption of blood cockle (Senilia senilis) and oyster (Crassostrea gasar) from Bonny Estuary, Rivers state Nigeria by analyzing the levels of the selected metals using Atomic Absorption Spectrometer Model A 200 AA. Data were used to calculate the non-carcinogenic health risk using Daily Intake Rate (DIR) Target Hazard Quotient (THQ) and Hazard Index (HI). The results showed variations in the concentration of the different heavy metals in the two shellfish. The trend of the metal concentrations in decreasing order was: Crassostrea gasar > Senilia senilis. Levels of metals in Senilia senilis, were all below the WHO and FAO permissible limit for fish. Also, all metals except Pb were below the WHO maximum permissible limit in Crassostrea gasar. The DIR (9.4684E-06 - 0.00281); THQ (8.286E-07 – 1.842E-04) and HI (2.519E-05 -2.595E-04) for all metals were below one indicating no risk for non-carcinogenic effects individually and collectively.  The shell fish analyzed from the Bonny Estuary are free from potential human health hazards from heavy metals. However, continuous monitoring of levels of metals in fish from the estuary is recommended.

Published: June 2022

This paper investigates the combined effects of radiant heat, local Nusselt number and Skin friction coefficient on a channel flow of third grade fluid in the presence of saturated porous medium. It is assumed that the fluid has temperature-dependent variable viscosity and thermal conductivity. The non-linear governing differential equations are obtained and tackled numerically using Spectral element technique and C++ programming language. Increase in the values of radiation parameter and third grade material parameter consequently increase the local Nusselt number and skin friction coefficient. Graphical results showing the effects of various physical parameters are presented and discussed quantitatively. It is concluded that Williamson’s fluid parameter served as a cooling factor in diverse improved technological processes in order to avoid different machines from overheating and enhance their efficiencies.

Increasing deterioration of coastal waters is a major public health concern in many regions of the developing world. This study investigates the impact of water quality on the proliferation of bacterial pathogens in surface water, sediment and tissues of fish, Sarotherodon melanotheron from the Makoko axis of Lagos Lagoon. Analysis of physicochemical characteristics and microbial quality of samples followed standard methods and procedures.  Measured water quality parameters (water temperature, turbidity, pH, salinity and dissolved oxygen) which showed no significant variation (p>0.05) across study stations were within the Nigerian Federal Environmental Protection Agency set limit The highest total bacterial count (TBC) (214.09±43.95 x 105 CFU g-1), total coliform counts (TCC) (91.15±15.05 ×104 CFU g-1) and total faecal coliform (TFC) (36.22±12.98×10³ CFU g-1) were recorded in fish muscle tissue while the lowest TBC (52.39±39.72 x 105 CFU ml-1), TCC (33.45±33.94 ×104 CFU ml-1) and TFC (0.19±0.18×10³ CFU ml-1) were recorded in water sample. The bacterial species with the highest percentages of occurrence in water, sediment, fish gill and fish muscle tissue were Klebsiella pneumoniae (22.11 %), Enterobacter aerogenes (32.37 %), Escherichia coli (32.97 %) and E. coli (29.00 %) respectively. A very strong positive correlation (r = 1.00) was obtained between TBC in water and salinity as well as with dissolved oxygen levels. Likewise, the TBCs in fish parts (muscle tissue and gill) were positively correlated with the water temperature and turbidity. On the other hand, a negative correlation was obtained between pH and TBC in fish muscle tissue (r = -0.81) as well as with fish gut (r = -0.77). The relatively high counts of pathogenic bacteria species recorded during the study have serious public health implications.

Published: June 2022

This study analysis the elemental composition and concentration of elements in the soils of the study area to ascertain degree of elemental enhancement in the soil resulting from anthropogenic activities with possible soil contamination, human health and environmental detriment. The study area was divided into eight grids and two soil samples per grid from over burden to a depth of 900mm was collected randomly in each grid. The samples were prepared using standard methods and analyzed with a linear accelerator. The number of detectable elements and their quantitative information was extracted from the elemental spectral signatures. . The result showed a high concentration value in some elements in the soil samples above values of elemental concentrations in soils from other reported studied region. In addition, Aluminium, Strontium, Barium, Gallium etc also showed an extremely high value in their concentration that exceeds the world wide mean range upper limit values in crustal soil study published. The study indicates some degree of potential contamination and therefore necessitate a regular periodic monitoring study to reduce potential health detriment to humans and the environment to as low as reasonably possible.

Published: June 2022

The protective activities of Gomphrena celosioides on Aspirin-induced alterations in biochemical markers were investigated in the kidney and liver of Wistar rats. Serum creatinine and blood urea nitrogen concentrations were assessed to determine biochemical alteration in the kidney, while total bilirubin and direct bilirubin concentrations were assessed to determine biochemical alteration in the liver. Four groups of rats were used.  In group 1, the control rats were treated with 1% Gum Acacia solution. Group 2 was treated with Aspirin at 200 mg/kg b.w alone. Group 3 was treated with Aspirin at 200 mg/kg b.w and G. celosioides at 500 mg/kg b.w while Group 4 received G. celosioides at 500 mg/kg b.w. All the administration and treatment lasted for 7 days. A significant increase (P < 0.05) in the concentrations of serum creatinine (69.60 ± 4.16 mg/dl), total bilirubin (38.36 ± 5.33 mg/dl), direct bilirubin (15.17 ± 2.22 mg/dl) and blood urea nitrogen (27.05 ± 4.85 mg/dl) was observed in the rats treated with 200 mg/kg b.w aspirin. There was significant decrease (P < 0.05) in the concentrations of creatinine, total bilirubin, direct bilirubin, and blood urea nitrogen in the rats in group 3 (59.58 ± 2.972 mg/dl, 31.41 ± 6.22 mg/dl, 11.09 ± 1.40 mg/dl, 13.12 ± 0.67 mg/dl) and in rats in group 4 (53.2 ± 1.16 mg/dl, 32.19 ± 3.36 mg/dl, 13.49 ± 4.06 mg/dl, 10.63 ± 3.16 mg/dl) when compared with  rats in group 2. While there was no significant (P < 0.05) difference when compared with group 1 (control) (52.20 ± 3.25 mg/dl, 30.75 ± 1.23 mg/dl, 12.46 ± 1.12 mg/dl, 7.29 ± 2.07 mg/dl).  The results reveal that G. celosioides can provide significant protection against biochemical alterations in aspirin-treated rats.

It is believed that certain environmental factors modulate coronavirus disease-19 (COVID-19). This review outlines the role of environmental factors in COVID-19 infectivity, spread, and severity. Relevant articles were retrieved from Google Scholar, SpringerLink, and Scopus, then pooled and duplicates removed with EndNote software. Available information reveals that temperature, relative humidity (RH), sunlight, pollutants, and population density modulate COVID-19 infectivity and pathogenicity. COVID-19 spread is promoted by low temperature (< 25 °C) and RH (< 40%), whereas it is inhibited by high temperature (> 25 °C) and RH (> 40%). Sunlight exposure alters the virus’s genetic material and boosts the host’s immune function by raising serum vitamin D (25-hydroxyvitanim D), reducing the virus’s viability and replication. Prolonged indoor stays with poor ventilation cause re-breathing of the air and increase carbon dioxide concentration, particularly in crowded rooms, predisposing to COVID-19. Pollutants, including particulate matter, nitrogen dioxide, ozone, and sulphur dioxide, may overexpress the virus’s receptor called angiotensin-converting enzyme 2 (ACE2), thereby increasing the virus’s infectivity. Pollutants may also induce inflammation of the respiratory tract, weakening the immune function and thereby increasing susceptibility to COVID-19. High population density increases body contact and thus susceptibility to the virus. To stem the incidence and mortality of COVID-19, the mentioned environmental factors must be kept at healthy levels.

Published: June 2022

AIMS OF THE STUDY: Limited information on medication safety may result in concerns on how to treat pregnant and breast-feeding patients. The Swiss Teratogen Information Service (STIS) provides information to healthcare professionals about medications during pregnancy and breast feeding. Our objective was to describe the queries addressed to the STIS over the past two decades.
METHODS: The STIS maintains a database of queries on pregnancy outcomes after exposure to various substances, which may be a valuable source of information. We initially analysed the general characteristics of all queries. Thereafter, we focused on exposure to medications during singleton pregnancies and associated health-related aspects.
RESULTS: From 2000 to 2019, 7148 queries were entered into the database. An increasing number of queries was recorded over the study period, with an average of 357 queries entered into the database per year. Most of the enquirers were physicians; more specifically, gynaecologists/obstetricians (2389/7148; 33.4%) and psychiatrists (1007/7148; 14.1%). Two thirds (4747/7148; 66.4%) of the queries addressed medication intake during pregnancy; the next most frequent queries concerned planned medication in the context of pregnancy (928/7148; 13.0%) or medication use during breast-feeding (873/7148; 12.2%). In more than 50% (3611/7148) of cases, women were treated with more than one drug; altogether, 15193 medications (taken alone or in combination) were identified. The most frequent queries concerned medicines for the nervous system (ATC group N, n = 7042), with selective serotonin reuptake inhibitors (n = 1271) in the leading position, followed by benzodiazepine derivatives (n = 1102) and other antidepressants (n = 780). The next most frequently mentioned drug classes were anti-infectives for systemic use (J, n = 1586) and drugs for the alimentary tract and metabolism (A, n = 1205). Analysis of follow-up information on cases of medication exposure during singleton pregnancies (n = 2672) revealed an offspring malformation rate of 4.2%. The organ system most often affected was the musculoskeletal system, followed by the circulatory system; congenital malformations of the nervous system and chromosomal abnormalities were also seen. The three most frequently documented congenital diagnoses were malformations of cardiac septa, the brain and major arteries.
CONCLUSIONS: Healthcare professionals often have concerns regarding the treatment of pregnant women with medication, and require professional counselling in this area. A variety of drugs are mentioned in queries addressed to the STIS, of which psycholeptics and psychoanaleptics are the most frequent. Proper guidelines on their use during pregnancy appear particularly urgent.

XYZ is a company engaged in the ceramics industry. One way maintenance is carried out on production machines is to use the cost of maintenance expenditure which aims to streamline and expedite the production process of both quality and quantity. In this study the cost pemeliharaan yang done is on a production machine roller kiln kiln mainly because if not maintained can quickly roll the kiln was dirty and broken so that it can directly increase the cost of expenditures (the smaller the efficiency of expenditures) for the purchase of a new kiln roll to replace the roll kiln dirty and broken. The method used in this study to determine the effect of roller kiln maintenance costs on the efficiency of spending is a statistic that is a quantitative method with simple linear regression (two variables). From the research results obtained regression equation y = 0.379 +1.110 X diliat coefficients table from SPSS, Efficiency of expenditure will be worth 0.379 if the company no roll maintenance costs. Each one-time increase in the cost of engine maintenance roll kiln then the efficiency corporate spending rose by 1.110. The cost of engine maintenance roll kilns have strong relationships with significant spending efficiency by 97.9% results from SPSS can diliat model summary table, the efficiency of spending can be influenced by other factors is the use of EUT. Average roll kiln is unplugged as much as 105.73 in round roll 106 at a price of Rp 300,000 a roll when not using the average maintenance cost per month can pay for purchases of new roll of 106 x 300 000 = 31.8 million. If using the maintenance costs (usage Grinding stone) at a price of Grinding stones, Rp. 1.800.000 to clean up the dirty roll kiln as many as 100-150 stems roll is clearly more efficient in spending compared With no use of maintenance costs

Authors: Abad Seminario Víctor
Published: June 2022

Las transacciones de fusiones y adquisiciones permiten a las partes intervinientes crear un régimen jurídico específico, y aplicable solo a ellas, que distribuye la responsabilidad por los bienes materia de compraventa (sean acciones, activos, o una combinación de estos últimos que resulten en un negocio en marcha). En el marco de estos regímenes jurídicos, se ha encontrado en el mercado de seguros una oportunidad para reducir riesgos mediante la contratación de pólizas que cubran escenarios de responsabilidad de los vendedores ante la falsedad, inexactitud o incumplimiento de las declaraciones y garantías que otorguen a los compradores, y que deriven en daños a estos últimos o a la compañía objetivo. En este artículo se aborda la complejidad de esta figura legal que, si bien no se ofrece directamente en el mercado peruano, viene tomando fuerza en la región.
