ABSTRACT
RESUMEN Una de las principales formas de contaminación de la leche con micotoxinas es el consumo de alimentos fermentados que se encuentran contaminados con mohos principalmente de Aspergillus spp., los cuales producen toxinas que pueden llegar a constituirse como un problema para la salud publica debido a su estabilidad térmica y química. El objetivo del presente trabajo fue detectar las concentraciones de aflatoxina M1 en muestras de leche de vacas en tanques de enfriamiento en cuatro municipios del departamento de Boyacá durante un año, determinando las variaciones de acuerdo con la temporada. Se realizó un estudio de corte longitudinal, descriptivo cuantitativo. Se seleccionaron aleatoriamente cuatro tanques de enfriamiento de cuatro municipios distintos del departamento; cada uno se muestreó dos veces al mes durante todo el período de estudio y se procesaron mediante metodología Charm Ez Lite . Se realizó un ANDEVA para determinar las diferencias estadísticas entre las concentraciones de la aflatoxina M1 por cada trimestre. Se determinaron diferencias estadísticas entre cada uno de los trimestres del estudio encontrando un porcentaje de positividad de 74,06% del total de muestras positivas en los trimestres de verano. 28,12% (108) de las muestras tomadas durante todo el estudio fueron positivas, con concentraciones de la toxina que oscilaron entre 0,5 y 2,0 μg/Kg de leche. Se determinó por primera vez en el departamento de Boyacá las concentraciones y variaciones estacionales de aflatoxina M1 en muestras de tanques de enfriamiento de leche, encontrando las mayores concentraciones y número de casos positivos de aflatoxina M1 en los meses de verano.
ABSTRACT One of the main forms of contamination of milk with mycotoxins is the consumption of fermented foods that are contaminated with mold, mainly Aspergillus spp, which produce toxins that can become a public health problem due to their thermal and chemical stability. The objective of the present work was to detect aflatoxin M1 concentrations in cows' milk samples in cooling tanks in four municipalities of the department of Boyacá for one year, determining the variations according to the season. A longitudinal, quantitative descriptive study was carried out, four cooling tanks from four different municipalities in the department were randomly selected, each tank, in each municipality, was sampled twice a month throughout the study period and processed using Charm methodology Ez Lite®, an ANDEVA was performed to determine the statistical differences between aflatoxin M1 concentrations for each quarter. Statistical differences were determined between each of the quarters of the study, finding a positivity percentage of 74.06% of the total positive samples in the summer quarters. 28.12% (108) of the samples taken throughout the study were positive, with toxin concentrations ranging between 0.5 and 2.0 μg/Kg of milk. Seasonal concentrations and variations of aflatoxin M1 in milk cooling tank samples were determined for the first time in the department of Boyacá, finding the highest concentrations and number of positive cases of aflatoxin M1 in the summer months.

Objective@#To analyze the correlation between the psychological flexibility of newly recruited nurses and the change leadership behavior of head nurses, so as to guide nursing managers to strengthen management and improve the quality of nursing care of new nursing staff.@*Methods@#From May 2017 to April 2018, 80 new nursing staff were surveyed using the psychological resilience scale and the change leadership style, and their correlation was analyzed.@*Results@#According to the statistics, the total score of psychological reinforcement of new nursing staff was (2.74±0.52)points, the overall level was not high, and the head nurses' change leadership behavior and various dimension scores were positively correlated with the nursing staff's psychological elasticity score (r=0.240, P<0.05).@*Conclusion@#Nursing managers should give full play to the role of the head nurses' transformational leadership behavior, so as to act on the psychological flexibility of nursing staff and improve the overall level of care.
ABSTRACT
The insertion of ‘susuk’ or charm needles is a practice common in Southeast Asia. It is a form of metallic talisman inserted subcutaneously in different parts of the body. This case report describes three patients (an 85-year-old Chinese man, a 53-year-old Malaysian woman and a 74-year-old Chinese woman) who were evaluated for knee and low back pain and were incidentally to have charm needles on their radiographs. None of these patients complained of any problem related to these charm needles.
ABSTRACT
Cinnabar is the mineral with mercury in combination with sulfur, and it has been used to make charms in China and Korea. If cinnabar is overheated, mercury vapor that is extremely hazardous or sometimes fatal can be released. We experienced 5 patients of a family who were exposed to mercury vapor when they burnt charms. One of them developed severe acute respiratory failure and the patient needed mechanical ventilation and extracorporeal membrane oxygenation (ECMO). Despite treatment with cortiocosteroid, D-penicillamine, ECMO and plasmapheresis, the radiologic findings of a patient worsened and he died.

Quality education calls for high quality teachers. The solemn mission of teachers requires them to possessgeneral inner qualities that meet the needs of the development of the era and the society. This paper first analyses thequality of the teacher from four aspects:ideal, personality, doing scholarly research and sentiment.
