В последние годы снизилось качество работ по отводу и таксации лесосек. Существующие и применяемые в таксации методы не обеспечивают необходимую точность конечных результатов, поскольку их использование часто не соответствует требованиям «Наставления по отводу и таксации лесосек». Таким образом, актуальной задачей становится изучение ошибок в определении товарной структуры древостоев и выявление возможных причин их возникновения с целью дальнейшего совершенствования лесотаксационных работ. На основании материалов таксации постоянных пробных площадей ели европейской была выполнена материально-денежная оценка древостоев по сортиментным и товарным таблицам, произведен расчет грубых, систематических и случайных ошибок выхода крупной, средней, мелкой деловой древесины, дров, ликвидной древесины и отходов. Для оценки влияния различных факторов на появление и величину ошибок были выполнены корреляционный и однофакторный дисперсионный анализы. Проведенный анализ позволил установить, что основными показателями, оказывающими влияние на расхождения в выходе сортиментов различных категорий древесины, при использовании товарных и сортиментных таблиц, являются средние высоты древостоев, а также разряды высот. Это связано с малым числом значений высот, представленных для каждой из ступеней толщины в товарных таблицах. Сортиментные таблицы, в силу большей вариабельности данного таксационного показателя, позволяют более точно определять товарную структуру древостоев. Выявленные закономерности демонстрируют необходимость совершенствования сортиментных и товарных таблиц для уменьшения расхождения получаемых результатов с фактическим выходом сортиментов, что позволит повысить качество лесотаксационных работ. In recent years, the quality of work on the allocation and taxation of cutting areas has decreased. Existing methods used in the taxation do not provide the required accuracy of results since their application often does not meet the criteria of the “Manual on the allocation and taxation of cutting areas”. Thus, the study of errors in determining the product structure of forest stands as well as identifying possible causes for their occurrence in order to improve forest taxation works becomes an urgent task. Based on the taxation materials of the permanent European spruce plots, material and monetary assessment of the stands was made using assortment and commodity tables, and gross, systematic, and random errors of the output of large, medium, small commercial timber, firewood, liquid wood, and waste were calculated. Сorrelation analysis and one-way analysis of variance were performed to assess the influence of various factors on the appearance and magnitude of the errors. The analysis made it possible to establish that the main indicators that influence the discrepancies in the output of assortments of different categories of wood, when using commodity and assortment tables, are the average heights of stands, as well as height categories. This is due to the small number of height values presented for each of the thickness steps in the product tables. Assortment tables, due to the greater variability of this taxation indicator, allow you to more accurately determine the product structure of stands. The revealed patterns demonstrate the high need to improve assortment and commodity tables in order to reduce the discrepancy between obtained results and the actual output of assortments, which will improve the quality of forest taxation work.

Currently, Ukraine and Kazakhstan are implementing health care reform, based on the introduction of new approaches to public administration in order to improve the accessibility and quality of providing medical services to the population. Studying the experience of such reform is an urgent task of the theory and practice of post-Soviet socio-economic transformations. A comparative analysis of medical reforms in the countries studied allows us to identify existing problems and propose solutions to them, taking into account their foreign experience in implementing them with a view to justifying and developing an effective mechanism for managing the industry. Analysis of the practice of public administration of the health care system in Kazakhstan and Ukraine concludes with a logical generalization and justification of priority measures of the state in this field. The limitation in the proposed study is the incompleteness of statistical bases, as well as the lack of generally accepted approaches and methods for assessing the health system.

This review paper deals with the use of statistical methods to evaluate systematic and random errors associated with trigonometric parallaxes. First, systematic errors which arise when using trigonometric parallaxes to calibrate luminosity systems are discussed. Next, determination of the external errors of parallax measurement are reviewed. Observatory corrections are discussed. Schilt’s point, that as the causes of these systematic differences between observatories are not known the computed corrections can not be applied appropriately, is emphasized. However, modern parallax work is sufficiently accurate that it is necessary to determine observatory corrections if full use is to be made of the potential precision of the data. To this end, it is suggested that a prior experimental design is required. Past experience has shown that accidental overlap of observing programs will not suffice to determine observatory corrections which are meaningful.

Kinerja perawat merupakan hasil yang dicapai dalam melaksanakan asuhan keperawatan di rumah sakit. Terciptanya asuhan keperawatan yang optimal sangat diperlukan dukungan dari pihak rumah sakit salah satunya adalah menciptakan kualitas kehidupan kerja baik bagi perawat. Penelitian ini bertujuan untuk mengetahui hubungan antara kualitas kehidupan kerja terhadap kinerja perawat pelaksana di RSUD Teluk Kuantan. Jenis penelitian kuantitatif dengan pendekatan cross sectional. Jumlah sampel 120 responden yang diperoleh melalui proportionate simple random sampling. Hasil penelitian menunjukkan kualitas kehidupan kerja perawat RSUD Teluk Kuantan berada pada kategori sedang, kinerja perawat berada pada kategori kurang baik. Berdasarkan analisis kedua variabel teridentifikasi bahwa tidak ada hubungan antara kualitas kehidupan kerja dengan kinerja perawat pelaksana dengan  p value 0,817. Dimensi work context merupakan komponen yang memiliki hubungan dengan kinerja perawat pelaksana dengan p value 0,008, dimensi work life  tidak berhubungan secara signifikan dengan kinerja perawat. Kesimpulan penelitian diketahui tidak ada hubungan antara kualitas kehidupan kerja dengan kinerja perawat pelaksana. Ada hubungan dimensi work context dengan kinerja perawat pelaksana. Tidak ada hubungan dimensi work life dengan kinerja perawat.   Kata kunci: kualitas kehidupan kerja, kinerja, perawat pelaksana   THE RELATIONSHIP BETWEEN THE QUALITY OF WORK LIFE AND THE PERFORMANCE OF IMPLEMENTERS NURSES   ABSTRACT Nurse performance is the result achieved in implementing nursing care in a hospital. The creation of optimal nursing care is very much needed support from the hospital, one of which is to create a good quality of work life for nurses. This study aims to determine the relationship between the quality of work life and the performance of nurses at the Kuantan District Hospital. This type of quantitative research with cross sectional approach. The number of samples of 120 respondents obtained through proportionate simple random sampling. The results showed that the quality of work life of nurses at the Kuantan District Hospital was in the medium category, the nurses' performance was in the unfavorable category. Based on the analysis of the two variables, it was identified that there was no relationship between the quality of work life with the performance of implementing nurses with a p value of 0.817. The work context dimension is a component that has a relationship with the performance of nurses implementing with p value 0.008, the dimension of work life does not significantly correlate with nurse performance. The conclusion of the research is that there is no relationship between the quality of work life and the performance of the implementing nurses. There is a relationship between the dimensions of the work context and the performance of the nurses. There is no relationship between the dimensions of work life and nurse performance.   Keywords: quality of work life, performance, implementers nurse
