Globally, it is estimated that the number of people living outside of their country of origin reached 281 million in 2020. The primary drive of those migrants when migrating voluntarily is work to increase their income and provide for their families left behind in their home countries. Those who migrate immediately seek means of income to sustain themselves through a perilous process as currently evidenced in the war in Ukraine and not too long ago in Syria and Venezuela. Unfortunately, migrant workers are globally known to predominantly be working in "4-D jobs"- dirty, dangerous, and difficult and discriminatory; the fourth D was recently added to acknowledge the discriminatory aspect and other social determinants of health migrant workers face in their host country while exposed to precarious work. Consequently, migrant workers are at considerable risk of work-related illnesses and injury but their health needs are critically overlooked in research and policy. Recognizing the UN Universal Declaration of Human Rights "Everyone has the right to work, to free choice of employment, to just and favourable conditions of work and to protection against unemployment", we cannot consider any human life - thus, the life of migrant workers - as dispensable through a structural discriminatory process that undervalues their occupational safety and health, livelihood and the contribution these workers bring to their host countries. This was seen during the preparation for the upcoming world cup in Qatar where migrant workers were exposed to a multiplicity of serious hazards including deadly heat hazards.

Objectives: The purpose of this study was to determine factors associated with non-vaccination against coronavirus disease 2019 (COVID-19) among the Venezuelan immigrant population residing in Peru. Methods: A cross-sectional study was conducted using data obtained from the Second Survey of the Venezuelan Population Residing in Peru in 2022. The dependent variable was vaccination status against COVID-19. The independent variables included socio-demographic, economic, and migratory characteristics of the included population. Crude and adjusted generalized linear Poisson-family models were used to calculate prevalence ratios with 95% confidence intervals (CIs). Results: A total of 7739 Venezuelan migrants aged 18 years or older were included. The proportion of non-vaccination against COVID-19 was 5.7%. Regarding associated factors, unemployment (adjusted prevalence ratio [aPR], 1.31; 95% CI, 1.04 to 1.65) was linked to an increased likelihood of not being vaccinated against COVID-19. In contrast, women (aPR, 0.76; 95% CI, 0.61 to 0.95), possessing a migration permit (aPR, 0.41; 95% CI, 0.31 to 0.54), and having health insurance (aPR, 0.47; 95% CI, 0.27 to 0.81) were associated with a decreased likelihood of being unvaccinated. Conclusions: The primary governmental and non-governmental institutions responsible for supporting and protecting the Venezuelan migrant and refugee population should improve vaccination access by issuing migration permits and providing health insurance.

Alley cropping field experiment has been carried out for 24 months in lime-stone based dryland farming area of southern Bali to study the chemical composition and nutritive value of 16 provenances of Gliricidia sepium The design was a completely randomized block: arrangement, consisted of 16 treatments (G. sepium provenances) and 6 blocks as replications with 12 plants per provenance. Of the 16 gliricidia provenances, six were from Mexico (M), four were from Guatemala (G), one each was from Colombia (C), Indonesia (I), Nicaragua (N), Panama (P), Costa Rica (R) and Venezuela (V). After 12 months establishment, the gliricidia were lopped at 150 cm height regularly 4 times a year, twice during the 4 months wet season and twice during the 8 months dry season. The highest ash, mineral, total soluble phenol, prussic acid and digestibility were in V1; the highest crude fiber component was in M39; the highest gross energy was in P13, while the highest organic matter was in M35. Based on the highest nutritive constituents, V1, C24 and G14 were ranked first, second and third respectively, while based on the lowest non-nutritive constituents C24, V1 and N14 were ranked first, second and third, respectively. The importance of such provenances as source of nutrients for the ruminant during the dry season were discussed.

Background: Most studies of human papilloma virus (HPV) are aimed at the natural history of the infection and its relation to cancer; however, there are few studies to assess knowledge of the general population. Our aim was analyze the degree of knowledge of Argentinians about HPV infection and its prevention. Materials and Methods: We conducted a voluntary, anonymous and non-binding survey with 27 multiple-choice items, in twelve private and public establishments, selected to include a broad population in terms of education, age and gender. The survey consisted of three sections: individual characteristics of the volunteer, HPV infection basic knowledge, its prevention and the virus relationship with other cancers. Results: One thousand two hundred ninety seven volunteers aged 18 to 80 participated. The total number of correct answers was 45.1%. The correct answers for relationship HPV and cervical cancer was 62.1%. Almost 55% did not know about types of HPV that the vaccines for protection. Statistical analysis showed that women, single people, workers, the better educated, those who have had a STDs or HPV and receiving information through medical or educational establishments had greater knowledge of the topic. Only 0.2% of participants answered all questions correctly. Conclusions: Knowledge plays an important role in health care and the deficiency found in our population could influence the success of the measures taken in the fight against cervical cancer. In this regard, we believe it would be appropriate, not only to emphasize early diagnosis and vaccine implementation, but also incorporate new communication strategies, facilitating reception of accurate and precise information by all strata of society.

본 연구에서는 공적개발원조(ODA), 해외직접투자(FDI), 수출과 수입 등 무역이 남미 경제발전에 어떠한 영향을 미치는지를 실증 분석하고자 하였다. 1960년~2014년까지 자료를 기반으로 실증분석 결과 브라질은 ODA 보다는 FDI와 무역이 경제성장에 지대한 영향을 미친 것으로 확인되었고, 아르헨티나는 FDI, ODA가 긍정적인 영향을 주었고, 베네주엘라, 페루의 경우에는 ODA가 FDI가 무역보다 더 경제성장에 큰 영향을 준 것으로 확인되었다. 이러한 실증분석 결과를 바탕으로 우리가 알 수 있는 것은 저개발국가의 경제성장을 위한 선진국들의 정책지원이 경제성장 단계에 따라 다르게 시행되어야 한다는 것이다. 경제발전 초기인 경우 ODA를 증대하여 경제성장의 기반을 조성하는 것이 필요하고, 경제성장의 도약기인 경우에는 FDI나 무역증대를 통해 경제성장을 촉진하는 정책실행이 중요하다는 시사점을 도출하였다.

Cracking and bulging in welded and internally lined pressure vessels that work in thermal-mechanical cycling service have been well known problems in the petrochemical, power and nuclear industries. However, published literature and industry surveys show that similar problems have been occurring during the last 50 years. A better understanding of the causes of cracking and bulging causes is needed to improve the reliability of these pressure vessels. This study attempts to add information required for increasing the knowledge and fundamental understanding required. Typical examples of this problem are the coke drums in the delayed coking units refinery process. This case was selected for experimental work, field study and results comparison. Delayed coking units are among the refinery units that have higher economical yields. To shut down these units represents a high negative economical impact in refinery operations. Also, the maintenance costs associated with repairs are commonly very high. Cracking and bulging occurrences in the coke drums, most often at the weld areas, characterize the history of the operation of delayed coking units. To design and operate more robust coke drums with fewer problems, an improved metallurgical understanding of the cracking and bulging mechanisms is required. A methodology that is based field experience revision and metallurgical analyses for the screening of the most important variables, and subsequent finite element analyses to verify hypotheses and to rank the variables according to their impact on the coke drum lives has been developed. This indicated approach provides useful information for increasing coke drum reliability. The results of this work not only order the most important variables according to their impact in the life of the vessels, but also permit estimation of the life spans of coke drums. In conclusion, the current work shows that coke drums may fail as a combination of thermal fatigue and other degradation mechanisms such as: corrosion at high and low temperatures, detrimental metallurgical transformations and plastic deformation. It was also found that FEA is a very valuable tool for understanding cracking and bulging mechanisms in these services and for ranking the design, fabrication, operation and maintenance variables that affect coke drum reliability.
