La rotación en Medicina Rural. ¿Existe? ¿Vale la pena?RAQUEL GÓMEZ BRAVO
The document discusses rural medicine rotations during medical residency training in Spain. It provides details about the speaker's experience doing a rural rotation in small towns in Madrid. Some key points made include:
- Rural rotations are becoming more popular and seen as an attractive option for young doctors to gain different experiences than urban settings
- Rotations provide benefits like shorter hours, financial incentives, housing assistance, and opportunities to get first job choices
- However, rural practice also presents challenges like isolation, long distances, lack of infrastructure and technology, and heavier workloads
- Studies show rural exposure during training is important for recruitment and retention of rural physicians later on

The document discusses ways to reduce math anxiety. It states that math anxiety is feelings of tension and anxiety that interfere with manipulating numbers and solving math problems. It is caused by factors like timed tests, public embarrassment, imposed authority, and lack of consideration for different learning styles in traditional classrooms. The document provides several suggestions to reduce math anxiety, including overcoming negative self-talk, practicing math daily, getting help immediately if something is not understood, and ensuring lessons are presented in multiple ways to accommodate different learning styles.
1.1 ¿Que Son Costos?
El costo se define como el valor sacrificado para adquirir bienes o servicios mediante la reducción de activos o al incurrir en pasivos en el momento en que se obtienen los beneficios.
1.2 Costos indirectos
Los costos indirectos pueden ser fijos o variables de acuerdo con la manera que respondan a los cambios en el volumen de producción o en alguna otra medida de las actividades.
1.2.1 Clasificación de los Costos indirectos
1.2.1.1 Por su comportamiento Variables
Costo cuyo total varía en forma directamente proporcional a los cambios en el nivel de actividades.
Ejemplos: Materia prima indirecta, Mano de obra indirecta pagada por hora, comisiones sobre ventas, energía eléctrica, la depreciación cuando se determine por el método de unidades producidas, etc.
1.2.1.2 Prorrateo
Reparto proporcional de una cantidad. Es la base para la asignación de un importe de manera proporcional y equitativa a cada departamento, por lo que se podrá distribuir un monto en forma proporcional a los activos, gastos, fondos y etcétera.
Por ejemplo, al cierre de ejercicio, la aplicación de gastos generales podrá ser distribuida a partidas tales como producción en proceso, artículos determinados de ventas, con base al importe a las unidades correspondientes a esas cuentas.
a) Prorrateo Primario
Consiste en distribuir y acumular los cargos indirectos primariamente entre los centros de producción y de servicios existentes. Para realizar el prorrateo primario es necesario utilizar una base de distribución y aplicar la fórmula siguiente:
Cargo indirecto/ base seleccionada = factor de distribución.
b) Prorrateo Secundario
Consiste en derramar o redistribuir los cargos indirectos acumulados en los centros de servicio a los diferentes centros de producción. Se realiza también a través de bases de distribución, empezando por los costos de los centros de mayor servicio proporciona a otros centros de producción, es decir, de los más generales a los menos generales, hasta los cargos indirectos queden acumulados en los centros productivos únicamente.
Esta operación contable tiene como finalidad hacer una derrama interpartamental, empezando a repartir los gastos del departamento que mayor proporcione; o sea, el que sirve amas departamentos, tomando como base el servicio recibido por los demás departamentos.
El principio del prorrateo secundario, es la aplicación de los gastos indirectos de cada departamento, en proporción al servicio otorgado y recibido; esto quiere decir que se prorratearan primero el gasto del departamento que mayor prestación suministre, entre los departamentos que lo hayan recibido; después en orden decreciente, se prorrateará el departamento que siga o continué, en cuanto el mayor servicio dado, entre aquellos departamentos que lo reciban, y así sucesivamente, hasta que por último queden los gastos indirectos acumulados exclusivamente en los departamentos.

Groups are defined as two or more individuals interacting and interdependent to achieve objectives. There are two types of groups: formal groups defined by organizational structure and informal groups that form naturally. The four types of groups are command, task, interest, and friendship groups. People join groups for status, self-esteem, affiliation, achievement of goals, power, and security. Groups generally pass through five stages of development: forming, storming, norming, performing, and adjourning.

1. MLCC stands for Multi Layer Ceramic Capacitor, which are widely used in electronic devices with approximately 250 components per mobile phone.
2. MLCCs are classified based on their dielectric properties and temperature range and can have capacitance values currently in the pF to 1μF range but nearing 50μF in the future.
3. Miniaturization of MLCCs is an ongoing technical trend, with common size codes decreasing from 1005 to 0603 and nearing 0402 to increase capacitance in smaller volumes.
NS107S pixel led, the upgrade of APA107ssuser7b8607
This document provides specifications and usage notes for the NS107S RGB LED. Key details include:
- The LED is used in SMD RGB strips and can be controlled for color and brightness levels.
- To prevent moisture damage, the LEDs are packed in aluminum bags with desiccant and should be stored in dry conditions. They should be soldered within an hour of opening the bag.
- The silicone coating provides optical and reliability benefits but can attract dust, so the LEDs should be kept dust-free before and after installation. Only isopropyl alcohol should be used for cleaning.

5. 6. Reliablity Test:
6.1.Simulated Reflow (Without solder): Samples for qualification testing require a
minimum of 3 passes of standard reflow solder profiles .2 hours of setting time
is required between each reflow profile test.
6.2.Static Humidity: Precondition at +25℃ for 1 hour.Then expose to +70℃ with 90 to
95% relative humidity for 120 hours.Finally dry at room ambient for 3±1 hours
before taking final measurement.
6.3.Temperature Shock: Each cycle shall consist of 15 minutes at -40℃,15 minutes at
+85℃ with a 20 seconds maximum transition time .Test duration is for 30 cycle ,
starting from cold to hot temperature.
6.4.ESD sensitivity: Perform ESD sensitivity threshold measurements for each contact
according to MIL-STD-883E,Method 3015 for Human Body Model and for Machine Model.
Identify the ESD threshold levels indicating passage of 2000V Human Body Model.
6.5.Random Vibrations: Vibrate randomly from 20 Hz to 2000Hz using the
Following Power Spectra Density(PSD) profile: It is a +3dB/octave .Starting with
0.01325g2/ Hz from 20Hz to 80Hz ,then 0.053g2/ Hz or 8g’s RMS level from 80Hz to
the PSD tolerance is ± 3dB from 20Hz to 1000Hz and ±6dB above 1000Hz .The
analyzer bandwidth to be set at 25Hz BW from 20Hz to 2000Hz , 50Hz BW to 1000Hz,and
finally 100Hz BW to 2000Hz ,The test time is 15 minutes per plane.
6.6.Mechanical Shock: Subject samples to half sine shock pulses(3000 g’s ±15% for
0.3ms )in each direction ,totally 6 shocks.
6.7.Operation Life: Subject samples to +85℃ for 168 hours under full rated power.
6.8. Solder Reflow: One pass through standard solder reflow profile.
6.9.Drop Test: Samples are fixed inside the fixture and droped naturally from the 2m
height onto a concrete plane in six direction for three times ,total 18 times .The
dimension of test fixture is 102(L)*54(W)*41(H)mm, and the weight is around 200g.
6.10.Sinusoidal Vibration: Vibrate randomly from 10Hz to 2000Hz ,1 octave/minute with
2mm amplitude (peak to peak) for 2 hours in each direction.
6.11.PC Board Solder Adhesion : Each test PC board shall contain only one part .Place
PC Board for testing upside down on two supports spaced 90mm apart centering the
part to within ±1mm of the span .Orient this part such that the longest dimension
is perpendicular between the two supports. Next using a force gauge ,also centering
to within ±1mm of the span’s center ,slowly apply a downward vertical force and
push with increasing force until the part’s terminations separate from the PC board.
Record at which deflection point mechanical failure occurs. Parts shall withstand
a minimum deflection as described below .Repeat for each test sample. Identify
precisely where termination stress failure(s) occur and include at least one
picture.
