    53 p. Recurso Electr?nicoTodo ser humano en el transcurso de la escuela sufre momentos cr?ticos lo que puede llevarlo a un estado de shock, situaci?n que puede dejar al sujeto en condici?n de vulnerabilidad al exponer sus condiciones al punto de dejar secuelas permanentes a nivel f?sico, psicol?gico y en casos desafortunados la muerte; Pero lo realmente importante es reconocer los factores neuro-pedag?gicos que determinan el inmovilismo ocasionado por el incidente critico en los ni?os de la instituci?n educativa Santa Ana de la zona rural de San Sebasti?n de Mariquita, Colombia; a partir del estudio y an?lisis de incidentes cr?ticos visto desde una l?nea interdisciplinar que agrupa principalmente a la pedagog?a y a las ramas de la psicolog?a y neurolog?a con el prop?sito de reconocer y caracterizar los posibles niveles de la conciencia y la posibilidad de entrenar la conciencia en niveles escolares. Palabras claves: incidente cr?tico, inmovilismo, patrones neuronalesEvery human being in the course of the school suffers critical moments that can take him to a state of shock, situation that can leave the subject in condition of vulnerability when exposing this conditions in to the point of leaving permanent sequels at the physical, psychological level and in unlucky cases the death; but the really important is recognize the neuro-pedagogical factors those determine the immobility caused by the critical incident in the children of the educational institution Santa Ana in the rural area of San Sebasti?n of Mariquita, Colombia; from the study and analysis of critical incidents seen from an interdisciplinary line that mainly groups the pedagogy and the branches of psychology and neurology with the purpose of recognizing and characterizing the possible levels of consciousness and the possibility of training the consciousness in school levels.

    Modifikasi kitosan dilakukan dalam rangka meningkatkan daya adsorpsi kitosan. Penambahan tripolyfosfat (TPP) dapat mempengaruhi kinerja kitosan untuk mengadsorpsi methyl orange. Penambahan cross-linker epiklorohidrin (ECH) bertujuan untuk meningkatkan stabilitas kimianya dalam kondisi asam serta membentuk pori kitosan beads lebih besar. Penelitian ini bertujuan untuk mengetahui konsentrasi dan lama perendaman TPP optimum pada adsorpsi methyl orange oleh kitosan. Konsentrasi TPP (1%, 5%, 10% dan 15% b/v) dan lama perendaman dalam TPP (1, 3, 6, 12, dan 24 jam) divariasi untuk mendapatkan jumlah methyl orange teradsorpsi optimum. Evaluasi kondisi optimum dilakukan dengan mengadsorpsi methyl orange dengan metode batch. Kondisi optimum diperoleh pada adsorpsi kitosan dengan konsentrasi TPP 10% dan lama perendaman selama 12 jam dengan jumlah methyl orange yang teradsorpsi mencapai 12,5 ± 0,744 mg/g. TPP berpengaruh pada pembentukan pori dan kekakuan kitosan beads. Karakterisasi SEM menunjukkan bahwa pori kitosan beads tergolong makropori dan pori partikulat. Spektra FTIR menunjukkan bahwa TPP telah mampu melindungi gugus NH2 dari kitosan tetapi masih tertinggal di dalam kitosan beads. Mekanisme adsorpsi lebih bersifat fisik karena spektra FTIR kitosan beads setelah adsorpsi tidak jauh berbeda dengan kitosan beads sebelum adsorpsi yang ditandai oleh serapan pada 2362 cm-1 yang menunjukkan terdapatnya methyl orange di dalam kitosan beads.Chitosan modifications performed in order to increase the adsorption capacity of chitosan. Addition tripolyfosfat (TPP) can affect the chitosan performance to adsorb methyl orange. The addition of cross-linker epichlorohydrin (ECH) aims to improve chemical stability in acidic conditions and to form larger pores of chitosan beads. This study aims to determine the concentration and immersion time TPP optimum in adsorption of methyl orange by chitosan. TPP concentrations (1%, 5%, 10% and 15% w / v) and immersion time in TPP (1, 3, 6, 12, and 24 hours) were varied to obtain the optimum amount of adsorbed methyl orange. Evaluation of the optimum condition is done by adsorption of methyl orange by the batch method. The optimum conditions obtained in the adsorption of chitosan with TPP concentration of 10% and a immersion time for 12 hours with the amount of adsorbed methyl orange reached 12.5 ± 0.744 mg/g. TPP effect on pore formation and stiffness chitosan beads. SEM characterization showed that the porous of chitosan beads classified as macropore and particulate pore. FTIR spectra showed that the TPP has been able to protect the NH2 group of chitosan but still lagging behind in the chitosan beads. Adsorption mechanism is more physical interaction because of the FTIR spectra of chitosan beads after adsorption is not much different from the chitosan beads before adsorption by absorption at 2362 cm-1 which indicate the presence of methyl orange in the chitosan beads

    Identification of acute myocardial infarction from electronic healthcare records using different disease coding systems

    Objective: To evaluate positive predictive value (PPV) of different disease codes and free text in identifying acute myocardial infarction (AMI) from electronic healthcare records (EHRs). Design: Validation study of cases of AMI identified from general practitioner records and hospital discharge diagnoses using free text and codes from the International Classification of Primary Care (ICPC), International Classification of Diseases 9th revision-clinical modification (ICD9-CM) and ICD-10th revision (ICD-10). Setting: Population-based databases comprising routinely collected data from primary care in Italy and the Netherlands and from secondary care in Denmark from 1996 to 2009. Participants: A total of 4 034 232 individuals with 22 428 883 person-years of follow-up contributed to the data, from which 42 774 potential AMI cases were identified. A random sample of 800 cases was subsequently obtained for validation. Main outcome measures: PPVs were calculated overall and for each code/free text. 'Best-case scenario' and 'worst-case scenario' PPVs were calculated, the latter taking into account non-retrievable/non-assessable cases. We further assessed the effects of AMI misclassification on estimates of risk during drug exposure. Results: Records of 748 cases (93.5% of sample) were retrieved. ICD-10 codes had a 'best-case scenario' PPV of 100% while ICD9-CM codes had a PPV of 96.6% (95% CI 93.2% to 99.9%). ICPC codes had a 'best-case scenario' PPV of 75% (95% CI 67.4% to 82.6%) and free text had PPV ranging from 20% to 60%. Corresponding PPVs in the 'worst-case scenario' all decreased. Use of codes with lower PPV generally resulted in small changes in AMI risk during drug exposure, but codes with higher PPV resulted in attenuation of risk for positive associations. Conclusions: ICD9-CM and ICD-10 codes have good PPV in identifying AMI from EHRs; strategies are necessary to further optimise utility of ICPC codes and free-text search. Use of specific AMI disease codes in estimation of risk during drug exposure may lead to small but significant changes and at the expense of decreased precision
