Incidenţa plăgilor accidentale şi unele incorectitudini tehnice în tratamentul lor la nivelul serviciului de urgenţă în arealul rural
No full textStudiul dat este bazat pe analiza adresărilor în serviciul de urgenţă în SRC Hînceşti a pacienţilor cu diferite traumatisme.
Plăgilor accidentale le revin 27.2%. Din ei în tratament staţionar au necesitat 8.1%. Restul au urmat tratament
ambulator, după prelucrarea primar chirurgicală a plăgilor. Majoritatea pacienţilor (52.2%) nu dispuneau de asigurare
medicală. Din această cauză mulţi din aceşti pacienţi rămân în afara vizorului medical, de unde reiese: pricina complicaţiilor
survenite în tratamentul plăgilor, în mare măsură revine ,,neglijenţelor” în tratament din partea pacienţilor şi
manajementului sanitar rural
Analiza performanțelor activității salariaților în entitățile economice din TIC
No full textFișierul atașat conține: Rezumat, Cuprins, Introducere, Bibliografie.Actualul management, la toate nivelurile sale, este foarte
puţin axat pe economia cunoaşterii, iniţiativă şi creativitate colectivă, a priori aceasta
vizează managementul firmelor. Cele mai multe firme autohtone implementează
principiul gestiunii autoritare şi unice, instituirea cunoştinţelor de sus, în timp ce, potrivit
savantului P. Drucker, tot mai activ sunt utilizate „echipe – pepeniere” , „echipe cu
autogestiune”, „echipe, formate pentru soluţionarea unor probleme specifice”. În acest
context, apare necesitatea de a stabili condiţii prealabile de recurgere la echipele
manageriale, la sursele şi componentele activităţii eficiente a acestora. Evaluarea
performanțelor este activitatea de bază a managementului resurselor umane, desfășurată
în vederea determinării gradului în care angajații unei entități îndeplinesc eficient
sarcinile sau responsabilitățile ce le revin. În general, performanța desemnează realizarea
obiectivelor organizaționale, oricare ar fi natura și varietatea acestora
Enzymatic hydrolysis and fermentation of ultradispersed wood particles after ultrasonic pretreatment
No full textAbstractBackgroundA study of the correlation between the particle size of lignocellulosic substrates and ultrasound pretreatment on the efficiency of further enzymatic hydrolysis and fermentation to ethanol.ResultsThe maximum concentrations of glucose and, to a lesser extent, di- and trisaccharides were obtained in a series of experiments with 48-h enzymatic hydrolysis of pine raw materials ground at 380–400rpm for 30min. The highest glucose yield was observed at the end of the hydrolysis with a cellulase dosage of 10mg of protein (204±21 units CMCase per g of sawdust).The greatest enzymatic hydrolysis efficiency was observed in a sample that combined two-stage grinding at 400rpm with ultrasonic treatment for 5–10min at a power of 10W per kg of sawdust. The glucose yield in this case (35.5g glucose l−1) increased twofold compared to ground substrate without further preparation.ConclusionsUsing a mechanical two-stage grinding of lignocellulosic raw materials with ultrasonication increases the efficiency of subsequent enzymatic hydrolysis and fermentation
Enzymatic hydrolysis and fermentation of ultradispersed wood particles after ultrasonic pretreatment
No full textBackground: A study of the correlation between the particle size of
lignocellulosic substrates and ultrasound pretreatment on the
efficiency of further enzymatic hydrolysis and fermentation to ethanol.
Results: Themaximumconcentrations of glucose and, to a lesser extent,
di- and trisaccharideswere obtained in a series of experiments with
48-h enzymatic hydrolysis of pine rawmaterials ground at 380\u2013400
rpm for 30min. The highest glucose yield was observed at the end of the
hydrolysis with a cellulase dosage of 10 mg of protein (204 \ub1 21
units CMCase per g of sawdust). The greatest enzymatic hydrolysis
efficiency was observed in a sample that combined two-stage grinding at
400 rpm with ultrasonic treatment for 5\u201310 min at a power of 10 W
per kg of sawdust. The glucose yield in this case (35.5 g glucose
l 121) increased twofold compared to ground substrate without
further preparation. Conclusions: Using a mechanical two-stage grinding

La gestión bajo una cultura de calidad en México: una verificación empírica.
No full textThis article points out what can be considered as “Management under a Quality Culture”, Total Quality Management [TQM] or simply Quality Management [QM], citing two contrasted points of view from international practitioners and researchers. Previous efforts of Mexican practitioners and consultants using case methods and empirical generalizations, consider and place TQM as a major trend and force change for the new millennium. It is argued that formal statistical researches testing TQM concepts and interrelations are scant. The author proposes and tests an aggregated structural equations model based on field data from his doctoral research information from 45 Mexican manufacturing firms. Data analysis is performed with SPSS and AMOS using regression and determination coefficients, with high degree of significance. In conclusion the author suggests additional strategies for future and more refined data analysis.El artículo presenta de entrada, enfoques administrativos que pueden ser englobados en el término “Gestión bajo una cultura de calidad” (GBCC), conocida internacionalmente como Total Quality Management [TQM], o simplemente Gestión de Calidad, citándose en seguida dos puntos de vista contrapunteados a nivel internacional en relación a este enfoque. Se presentan esfuerzos previos de consultores e implantadores mexicanos que, en base al método de casos y de generalizaciones empíricas de sus experiencias profesionales, consideran a la GBCC como una de las grandes tendencias y fuerzas de cambio en el siglo XXI. Se hace referencia a la escasez de investigaciones en las que se ponga a prueba estadísticamente los conceptos de teóricos, practicantes y consultores del área de la calidad. El autor propone y pone a prueba un modelo agregado de ecuaciones estructurales basado en datos de campo de su investigación de doctorado aportados por 45 empresas manufactureras mexicanas. El análisis de datos, realizado con los paquetes de software SPPS y AMOS, arroja coeficientes de regresión y de determinación, así como niveles de bondad del ajuste, altamente significativos. Al concluir, el autor sugiere estrategias adicionales para refinar futuros análisis de datos
La nueva contraloría social en la gestión pública mexicana

Mapa de mercado, una herramienta estratégica
No full textDue to the strong competition, the product sales substitutes have become a complex subject for the market people. The market analysis contains a complex mixture of variables that are difficult to interpret. The author proposes a strategic matrix that provides to the market analyst a tool to very low cost, in order to try to know its competitive position present, as well as the one of its opponents and the tendency towards where their commercial possibilities are directed.Debido a la fuerte competencia, las ventas de productos sustitutos se han convertido en un tema complejo para los mercadólogos. El análisis de mercado contiene una compleja mezcla de variables que son difíciles de interpretar.
