The models discussed so far have been, effectively, asexual.We have considered fertility in terms of females and their daughters, but we have used pooled survivorship data to derive model mortalities. In so doing, we have assumed an equal sex ratio at birth and equal sex-specific mortality rates. This introduces some error, and the direction is probably known: pre-industrial males have generally a higher adult survivorship than females, although the sex ratio may vary from age to age and from group to group (Weiss 1972b). Given our purpose and the quality of data available to anthropologists it is doubtful that the error introduced in this way is significant. A fieldworker who insists on constructing 2-sex models must have a larger data sample, so that the stochastic variations in age-class representation are minimized. But if the data seem sufficient and a 2-sex demographic model is desired, this chapter will present the methods by which such a model can be constructed.

The designation “Roll‐Along” is used to indicate the use of horizontal‐data‐stacking techniques when field data are derived by the shooting method. The term “Drop‐Along” is used for weight‐drop data. These methods have proven valuable in obtaining usable data in areas where the standard pattern techniques are ineffective, or where extreme multiplicity requirements make patterns economically impractical. Operational techniques have been developed for both Roll‐Along and Drop‐Along in which standard field recording equipment and cables are utilized. A discussion of these techniques and the associated data processing operations is presented. Record‐sections are used to illustrate the quality of data obtainable by these methods and to compare it to pattern shooting.

The mortality rate and life expectancy are the most important characteristics of public health, depending on the country’s socio-economic development, living conditions, and the quality of the living environment. At the state level, excess mortality at the working-age is recognized as an important reason for the low life expectancy of Russians. The objective of the study is to analyze the trend in the mortality rate and life expectancy of the employable age population of the Kemerovo region during 2011-2018. Material and methods. To estimate the mortality rate, the general and age-specific mortality rates, mortality rates by significant classes and individual causes of death were used. The life expectancy of the employable age population was calculated using temporary mortality tables based on age-specific mortality rates. A graphic analysis of the dynamics of age-specific mortality rates and the life expectancy in men and women of employable age in urban settlements, rural areas and the entire population of the Kemerovo region was carried out over five-year age intervals for 2011-2018. Statistical data obtained on the website of Rosstat. Results. In 2018, in the Kemerovo region, the mortality rate of 40-44 year men in urban settlements, 35-44 years old in rural areas, and women 35-44 years old in urban settlements and rural areas exceeded the level of 2011, which negatively affected the dynamics of life expectancy. In rural areas, due to these age groups, the life expectancy in men decreased by 0.57, women - by 0.41 years. Losses in urban settlements were minor. Conclusion. When developing regional socio-demographic programs, it is necessary to consider the identified features of mortality of the employable age population. An increase in life expectancy is impossible without overcoming the socio-economic crisis, improving health care financing, and increasing the availability and quality of medical care. A person should be interested in improving his health, saving his life. It is necessary to raise the level of culture, education, change the mentality.

Health Care Delivery Systems

As the consumers and regulators of health care have become more concerned with quality of delivered services, interest has focused on hospital- and physician-specific mortality rates as an index of quality. Mortality rates have several characteristics that promote their use as a performance indicator. The numerator, death, is generally (but perhaps incorrectly) accepted as an adverse outcome of health care. Death is thought to be easily measured, and is recorded in several locations, including the medical record abstract and death certificates, where the information is accessible without provider consent. The denominator, persons or patients, is also available from several public sources. The desirability of mortality data is further enhanced by the wide variety of statistical methods to manipulate and compare rates and proportions. The conceptual validity of mortality rates as reflecting quality is supported by a long tradition of using mortality rates at the “macro” level to compare the quality of national health care delivery systems (eg, infant mortality rates) and at the “micro” level to compare the outcome of different therapies (eg, thrombolytics for acute myocardial infarction). However, despite face validity, ease of measurement, and widespread acceptance in other areas, hospital-specific mortality rates, as calculated from current data sources, have a variety of potential problems.This article will explore the clinical, administrative, and information-based difficulties in using mortality rates as an indicator of the quality of medical care delivered by specific hospitals or physicians.

One goal in electron microscopy of biological specimens is to improve the quality of data to equal the resolution capabilities of modem transmission electron microscopes. Radiation damage and beam- induced movement caused by charging of the sample, low image contrast at high resolution, and sensitivity to external vibration and drift in side entry specimen holders limit the effective resolution one can achieve. Several methods have been developed to address these limitations: cryomethods are widely employed to preserve and stabilize specimens against some of the adverse effects of the vacuum and electron beam irradiation, spot-scan imaging reduces charging and associated beam-induced movement, and energy-filtered imaging removes the “fog” caused by inelastic scattering of electrons which is particularly pronounced in thick specimens.Although most cryoholders can easily achieve a 3.4Å resolution specification, information perpendicular to the goniometer axis may be degraded due to vibration. Absolute drift after mechanical and thermal equilibration as well as drift after movement of a holder may cause loss of resolution in any direction.

Mesoscale Structures

This work develops a new method, the box-balance model (BBM), to assess the role of hydrodynamic structures in the survival of fish larvae. The BBM was applied in the northwest Mediterranean to field data, on 2 small pelagic fish species whose larvae coexist in summer: Engraulis encrasicolus, a dominant species, and Sardinella aurita, which is expanding northwards in relation to sea warming. The BBM allows one to quantify the contribution of circulation, with significant mesoscale activity, to the survival of fish larvae, clearly separating the effect of transport from biological factors. It is based on comparing the larval abundances at age found in local target areas, associated with the mesoscale structures (boxes), to those predicted by the overall mortality rate of the population in the region. The application of the BBM reveals that dispersion/retention by hydrodynamic structures favours the survival of E. encrasicolus larvae. In addition, since larval growth and mortality rates of the species are required parameters for application of the BBM, we present their estimates for S. aurita in the region for the first time. Although growth and mortality rates found for S. aurita are both higher than for E. encrasicolus, their combined effect confers a lower survival to S. aurita larvae. Thus, although the warming trend in the region would contribute to the expansion of the fast-growing species S. aurita, we can confirm that E. encrasicolus is well established, with a better adapted survival strategy.

The Cost

The accuracy in administering the diagnosis code was the important matter for medical recorder, quality of data was the most important thing for health information management of medical recorder. This study aims to know the coder competency for accuracy and precision of using ICD 10 at X Hospital in Pekanbaru. This study was a qualitative method with case study implementation from five informan. The result show that medical personnel (doctor) have never received a training about coding, doctors writing that hard and difficult to read, failure for making diagnoses code or procedures, doctor used an usual abbreviations that are not standard, theres still an officer who are not understand about the nomenclature and mastering anatomy phatology, facilities and infrastructure were supported for accuracy and precision of the existing code. The errors of coding always happen because there is a human error. The accuracy and precision in coding very influence against the cost of INA CBGs, medical and the committee did most of the work in the case of severity level III, while medical record had a role in monitoring or evaluation of coding implementation. If there are resumes that is not clearly case mix team check file needed medical record the result the diagnoses or coding for conformity. Keywords: coder competency, accuracy and precision of coding, ICD 10
