This chapter examines the law of set-off in Chile, both before and after insolvency, as well as the alternatives for contractual set-off structures that may be agreed among two or more parties. In Chile, set-off was created as a legal concept primarily on the basis of practical considerations rather than juridical principles. The right to set-off may arise due to a contractual arrangement between the parties or by the operation of law, including the Chilean Civil Code. The chapter first considers set-off in Chile outside insolvency, focusing on set-off by operation of law and contractual set-off, before discussing set-off in insolvency. In particular, it explains the implications of a declaration of liquidation under Chilean Bankruptcy Law and its possible consequences for set-off rights. It also analyses issues arising in cross-border set-off.

Open Cnc System

As a cover to prevent the inside system from being destroyed, conical shell is widely used in national defense and meteorological fields. Radial runouts at specific cross sections of conical shell need to be measured before and after gluing for coaxiality requirement between conical shell and connecting ring. So a measuring system of vertical gluing platform was designed. Noncontact laser displacement sensor was adopted in the measuring system for advantages of quick data acquisition, high measuring accuracy and no surface scratch. Compared with traditional measuring method by a dial indicator, laser displacement sensor is more appropriate to carry out the measurement on the surface of conical shell. An open CNC system was developed for the measurement. It was based on industry personal computer (IPC) which and took motion control board and data acquisition board as its core. Experiments were conducted on the designed measuring system to find out the factors which influence measuring results. Measuring data showed that measuring results appeared to be a parabolic distribution in the working range of the sensor and the symmetry axis of the parabola was at the middle position. The variation of incident angle has no obvious influence on measuring results.

AbstractMesoscale intrathermocline lenses are observed throughout the World Ocean and are commonly attributed to water mass anomalies advected from a distant origin. An alternative mechanism of local generation is offered herein, in which eddy–wind interaction can create lens-shaped disturbances in the thermocline. Numerical simulations illustrate how eddy–wind-driven upwelling in anticyclones can yield a convex lens reminiscent of a mode water eddy, whereas eddy–wind-driven downwelling in cyclones produces a concave lens that thins the mode water layer (a cyclonic “thinny”). Such transformations should be observable with long-term time series in the interiors of mesoscale eddies.

The study aims to identify the effectiveness of a structural theory-based training program in enhancing the teaching practices of Arabic language teachers teaching grade ten in South Al Batinah in Sultanate of Oman. The study used the quasi-experimental design, and the sample consisted of 40 male and female teachers. To achieve the objectives of the study, a training program, an observation form and a measurement tool of teachers’ tendencies towards a structural teaching were made. The program was implemented with an experimental group of 20 female and male teachers in the first semester of the academic year 2018/2019. The study has found that there is a statistically significant difference between the average grades before and after implementing the program, with higher grades achieved after implementation. There has also been no statistically significant difference between the average grades in the post implementation phase due to the social variable. The researcher recommended organizing training courses for Arabic language teachers to expand their knowledge of educational theories and their applications in classroom teaching practices, and benefiting from the structural teaching observation form in educational supervision.

This paper explains how focused implementation of a broad range of technologies was used as the key strategy resulting in the establishment of highly efficient, dedicated facility for manufacture of gas turbine disk, hub, and drum rotor components. The physical and operational constraints associated with the conversion of an existing operating facility, along with the rigid time constraints, required a carefully phased and integrated plan. Reviews and tradeoffs of each of the many available manufacturing technologies are discussed and those selected, such as flowline units, group technology, rule based design/manufacturing and product improvement teams are explained in the context of their implementation phase-in. Before and after performance results are provided and on-going enhancements of this manufacturing system are covered.

OBJECTIVE The goal of this study was to compare the rate of dosing errors for antibiotic orders in pediatric patients before and after the implementation of an antibiotic standard dosing table with precalculated dosage for different weight ranges at a tertiary care hospital. METHODS A retrospective study of 300 antibiotic prescriptions for pediatric patients in three different settings (ambulatory care, inpatient, and emergency department) at a tertiary care hospital assessed the appropriateness of antibiotic dosing. The need for an antibiotic dosing standardization policy was identified after finding that more than 30% of patients experienced a dose variation of ±10% of the recommended daily dose. An antibiotic dosing standardization policy was implemented with an antibiotic standard dosing table for different weight ranges, and a hospital wide-education program was conducted to increase awareness of this new practice and its benefits. Three months after implementation, a random sampling of 300 antibiotic prescriptions collected from the same settings as the pre-intervention period was evaluated for compliance with the new policy and its effect on the number of antibiotic dosing errors. RESULTS Six hundred prescriptions were included in this study (300 in the pre-implementation phase and 300 in the post-implementation phase). Patient characteristics were similar in both groups in terms of sex, age, and weight. Physician compliance with the antibiotic dosing standardization policy after its implementation was 62%. The dosing standardization policy reduced the rate of dosing errors from 34.3% to 5.06% (p=0.0001), and weight documentation on the antibiotic prescription improved from 65.8% to 85.7% (p=0.0001). CONCLUSIONS Implementation of an antibiotic dosing standardization policy significantly reduced the incidence of dosing errors in antibiotics prescribed for pediatric patients in our hospital.

165 Background: The Hematology Hospital Outpatient service at Rochester Methodist Hospital provides ambulatory outpatient care to patients who would normally be hospitalized on our inpatient services due to cytopenias and need for infusion/transfusion support. A quality project was conducted to streamline our process and decrease wait times. Methods: This project was a part of a Mayo Lean Collaborative initiative to increase customer satisfaction and eliminate waste. The first step was to collect baseline measurements to capture the non-value added waiting time of our entire outpatient process. These benchmark times were collected from 65 patients over 4 days. We evaluated these wait times to identify gaps in care and factors contributing to delays in our process. Data collected "before and after" each implementation phase determined if the change was beneficial. Results: Through our data collection, one major area of opportunity we identified was the wait time for CBC results. At baseline, patients were waiting in a room for 61.9 minutes for lab results. A major contributor to delay was the lack of carriers to send blood samples through the tube system being stocked in the outpatient area. We also discovered that the time from when the sample was placed in the carrier to the time it arrived in our lab was significant. Through a process analysis it was identified that the CBC tubes were being sent to a central lab prior to their final destination in the Hematology lab. We were able to re-route our CBCs directly to the hem lab. Data collected after the intervention showed we were receiving results at 51 minutes, therefore, eliminating 10.9 minutes off of an appointment. We also identified additional opportunities such as pre-assigning rooms, scheduling, exam room organization, and communication that were able to be addressed. Conclusions: As a result of this lean collaborative project we reduced patient wait time by 20.1 minutes and increased patient satisfaction. We were able to order interventions sooner thereby increasing patient safety. By process analysis, we identified multiple areas in our process that could be shortened with no additional cost.

Background: Early evidence supports preferential transport of patients with stroke symptoms to primary stroke centers. While validated stroke tools exist for screening of stroke symptoms in the prehospital setting, system wide triage performance of prehospital providers in a regionalized system has not been reported. The objective of this study is to assess the diagnostic ability of prehospital providers, before and after regionalization of care, using outcomes based approach. Methods: This is a cross-sectional study of all patients who were transported to hospitals in two Northern California counties by providers of a single EMS agency during a three year period. One county remained non-regionalized (NR) during the study period and the other initiated and completed regionalization(R) of the system during the study period. Patient demographic data, prehospital provider clinical assessment was obtained from the computerized prehospital transport records and physician diagnosis was obtained from statewide administrative patient discharge data. The data sources were linked using probabilistic linkage methodology. Patients ≥18 years of age with validated ICD- 9 code for stroke were included. We excluded inter-facility transports and direct admissions. Sensitivity, specificity and predictive values for were determined before and after implementation of regionalization. Data analysis was performed using SAS version 9.2. Results: The total number of medical related EMS transports for 3 years was 310,731 and the number of patient discharges with a primary diagnosis of stroke was 10,298. We were able to link 3736 stroke records which indicate EMS use by 36% (3736/10,298) stroke patients. The sensitivity, specificity, PPV and NPV in the pre-regionalization phase was 28%, 80%, 53%, 58% and during the implementation phase of regionalization was 39% 78%,57% and 63% (p <0.05). The performance in the NR County during the entire period was 23%, 76%, 40% and 58%. Conclusions: Diagnostic accuracy remained low although improved prehospital provider performance was observed after regionalization of stroke care.

<p><strong>ABSTRACT</strong></p><p><strong>Background: </strong>Inaccurate documentation of medication histories may lead to medication discrepancies during hospital admissions. Obtaining a best possible medication history (BPMH) for warfarin can be challenging because of frequent dosage changes and nonspecific directions of use (e.g., “take as directed”). On February 27, 2012, the study hospital implemented an admission medication reconciliation (MedRec) process using a form that compiled the most recent 6 months of outpatient prescription dispensing history from a provincial electronic database called PharmaNet. It was unclear whether admission MedRec had improved the process of obtaining warfarin BPMHs and the quality of their documentation.</p><p><strong>Objective: </strong>To compare the rates of complete warfarin BPMH documentation before and after implementation of PharmaNet-based admission MedRec.</p><p><strong>Methods: </strong>A single-centre, retrospective chart review was conducted using the health records of patients receiving warfarin who were admitted to the hospital’s Internal Medicine service before and after implementation of admission MedRec. The study periods were October 1, 2009, to February 26, 2012, and February 27, 2012, to July 31, 2014, respectively. The primary outcome was the rate of complete warfarin BPMH documentation during each period.</p><p><strong>Results: </strong>Data were recorded for 100 patients in the pre-implementation phase and 100 patients in the post-implementation phase. The rates of complete warfarin BPMH documentation were 65% and 84% in these 2 phases, respectively (<em>p </em>= 0.002).</p><p><strong>Conclusion: </strong>Implementation of PharmaNet-based admission MedRec was associated with a statistically significant increase in the rate of complete warfarin BPMH documentation.</p><p><strong>RÉSUMÉ</strong></p><p><strong>Contexte : </strong>La consignation inexacte des schémas thérapeutiques peut mener à des divergences au chapitre des médicaments durant l’hospitalisation. Il peut être difficile d’établir un meilleur schéma thérapeutique possible (MSTP) pour la warfarine à cause de fréquents changements de posologie et de modes d’emploi imprécis (par exemple, « usage connu »). Le 27 février 2012, l’hôpital où s’est déroulée l’étude a mis en place un processus de bilan comparatif des médicaments (BCM) à l’admission. Celui-ci emploie un formulaire dressant la liste des médicaments d’ordonnance délivrés aux patients externes au cours des six derniers mois selon PharmaNet, une base de données numérique provinciale. On ignorait si les BCM à l’admission avaient amélioré le processus d’obtention et la qualité de la consignation des MSTP liés à la warfarine.</p><p><strong>Objectif : </strong>Comparer les taux de MSTP relatifs à la warfarine parfaitement consignés avant et après la mise en place d’un processus de BCM à l’admission qui s’appuie sur PharmaNet.</p><p><strong>Méthodes : </strong>Une analyse rétrospective des dossiers médicaux de patients menée dans un seul centre a été réalisée.

BackgroundScreening for neonatal hyperbilirubinaemia in the postnatal ward has traditionally been performed using serum bilirubin sampling, but this has significant drawbacks such as risk of infection and slower reporting time.ObjectiveWe aimed to assess the impact of introducing transcutaneous bilirubin (TcBR) testing using TcBR nomogram on the number of serum bilirubin samples sent.MethodsA before-and-after study was performed following the introduction of a protocol integrating the use of the Dragger JM-105 transcutaneous bilirubinometer in the postnatal ward. Only babies born at ≥37 weeks of gestation, weighing ≥2500 g who presented with jaundice after the first 24 hours and within the first 7 days of life were included in the study. The number of total serum bilirubin samples (TSBRs) sent were compared for the 6-month periods before and after (a total of 12 months) implementation of the new protocol.ResultsIn the pre-implementation phase, a total of 882 (49%) out of 1815 babies had at least one serum bilirubin sample taken as opposed to a total of 236 (17%) out of 1394 babies in the post-implementation phase. The odds of performing TSBRs at least one time among babies in post-implementation phase were 79% lower than in pre-implementation phase (OR 0.21, 95% CI 0.18 to 0.25). We also estimated a significant cost saving of approximately US$1800 over a period of 6 monthsConclusionTcBR testing used in conjunction with our proposed nomogram significantly reduces the need for serum bilirubin sampling.
