Обозначена важность своевременного учета качества и состояния живых изгородей, как многофункционального элемента городского ландшафта. Существующая методика инвентаризации не принимает во внимание распространенные проблемы живых изгородей. Предложена авторская методика, эффективность которой состоит в простоте учета, где фиксируются видимые проблемы структуры изгороди - параметры выпадов, и наглядности полученных расчетных данных, позволяющих сравнительно оценить качество изгородей и выбрать адекватную стратегию по улучшению их состояния. Введено понятие - общая целостность живой изгороди, которая показывает удельную протяженность ненарушенных выпадами участков изгороди, выраженную в процентах. Методика апробирована на 19 объектах общего пользования центрального района города Йошкар-Олы. Выявлены нарушения структуры изгородей: снижение их целостности вследствие наличия выпадов в количестве от 0,2 до 2 шт. /10 пог. м и протяженностью 0,7 до 4,8 пог. м. Различная протяженность выпадов требует различных подходов к их восстановлению. We determined the importance of timely consideration of the quality and condition of hedges as a multifunctional element of the urban landscape. The existing inventory methodology does not take into account the common problems of hedges. The authors’ methodology effectiveness is in the simplicity of accounting, where the visible problems of the hedge structure (gaps parameters) are recorded and the clarity of the calculated data is obtained. That allows us to comparatively assess the quality of hedges and choose an adequate strategy to improve their condition. The concept of general hedge integrity is introduced, which shows the specific length of hedge sections not disturbed by gaps, expressed as a percentage. The method has been tested on 19 public facilities in the central district of Yoshkar-Ola city. Violations of the structure of hedges were revealed: a decrease in their integrity due to the presence of gaps in an amount from 0.2 to 2 pcs. per 10 running meters and with length from 0,7 to 4,8 running meters. Different lengths of gaps require different approaches to their recovery.

The compaction quality of the subgrade is directly related to the service life of the road. Effective control of the subgrade construction process is the key to ensuring the compaction quality of the subgrade. Therefore, real-time, comprehensive, rapid and accurate prediction of construction compaction quality through informatization detection method is an important guarantee for speeding up construction progress and ensuring subgrade compaction quality. Based on the function of the system, this paper puts forward the principle of system development and the development mode used in system development, and displays the development system in real-time to achieve the whole process control of subgrade construction quality.

Required Quality

In construction production, the safety of constructing buildings and structures is achieved by ensuring the required quality as a result of systematic construction control based on the implementation of a complex of technical, economic and organizational measures at all stages of the object's life cycle. The article deals with the actual problem of improving the quality of construction products-buildings and structures in conjunction with the activities of construction control bodies. The article presents the advanced foreign and domestic experience of ensuring the quality control at the construction sites, providing for the prevention of the underlying causes of defects and increasing the interest of the contractors directly. On the basis of the analysis of the current situation with quality control at the construction market, ways to improve its efficiency by developing a unified system of technological implementation of relevant requirements for the quality of construction products, determining the rational number and business load of construction control engineers, as well as the active activities of self-regulatory organizations in this area are offered.

Subject. The study addresses the improvement of risk management efficiency and the quality of lending decisions made by banks. Objectives. The aim is to present the bank management with a fair algorithm for risk management motivation on the one hand, and the credit management (business) on the other hand. Within the framework of the common goal to maximize risk-adjusted income from loans, this algorithm will provide guidelines for ‘risk management’ and ‘business’ functions on how to improve individual and overall efficiency. Methods. The study employs the discriminant analysis, type I and II errors, Lorentz curve modeling, statistical analysis, economic modeling. Results. The paper offers a mechanism for assessing the quality of risk management decisions as opposed to (or in support of) decisions of the lending business when approving transactions. The mechanism rests on the approach of stating type I and II errors and the corresponding classical metric of the Gini coefficient. On the ‘business’ side, the mechanism monitors the improvement or deterioration of the indicator of changes in losses in comparison with the market average. Conclusions. The study substantiates the stimulating ‘rules of the game’ between the ‘business’ and ‘risk management’ to improve the efficiency of the entire business, to optimize interactions within the framework of internal competition. It presents mathematical tools to calculate corresponding indicators of the efficiency of internally competing entities.

We developed and implemented an annual online survey to administer to residents exiting residency training in order to (1) assess the quality of the residency experience and (2) identify areas of strength and areas requiring improvement. Long-term goals include program planning, policy-making and maintenance of quality control. Survey content was developed from an environmental scan, pre-existing survey instruments, examination of training criteria established by the CFPC and the CanMEDS criteria established by the RCPSC. The survey included evaluation benchmarks and satisfaction ratings of program director and faculty, preparation for certification and practice, quality of life, quality of education, and work environment. The response rate was 28%. Seventy-five percent of respondents were exiting from Royal College training programs. Results of descriptive statistics determined that the overall educational experience was rated highly, with 98.9% of respondents satisfied or very satisfied with their overall patient care experience. Ninety-six percent of respondents were satisfied or very satisfied with the overall quality of teaching. Preparation for practice was identified as needing improvement, with 26% and 34% of respondents giving an unsatisfactory rating to career guidance and assistance with finding employment, respectively. Although 80% of respondents reported receiving ongoing feedback and 84% discussed their evaluations with their supervisors, only 38% of evaluations were completed by the end of the rotation. The results indicate that residents are generally satisfied with their experiences during residency training, especially with their overall educational experience. Areas of improvement include preparation for practice and timeliness of evaluations. Further iterations of this survey are needed to refine the instrument, identify data trends and maintain quality control in residency training programs. Frank JR (ed.).

The purpose of this research was to find out the students' ability in applying Possessive pronoun in writing sentences and the problems encounter it.  This mixed method study employs an explanatory design to reveals it. 53 students out of 105 students from1st semester EFL students from one reputable University in Pekanbaru, Indonesia, were invited to this study. These 53 students were selected using simple random sampling and enrolled for an essay test and interview to see the students' ability and explaining the problems. The data analysis using SPSS showed that the average score of students was 52.98. Meanwhile for the median is 48, the mode is 20. The score of Standard Deviation is 27.93, Variance is 780.25, and Range is 84.  Z-Score was found 41.5%, which is means higher than average and 58.5% while, students' ability was indicated below the average. It showed that the students were low ability in applying possessive pronoun in writing sentences. The study also found the common problems, i.e., (1) students still mixed up between possessive pronoun and possessive adjectives. (2) students used the wrong pattern in using a possessive pronoun. (3) students did not understand clearly about a possessive pronoun, (4) experiencing difficulties in learning possessive pronoun.
