Based on the analysis of the results of ultrasonic testing, a quantitative assessment of the influence of the human factor on the PoD curves built for independent inspectors, several (different) flaw detection techniques was obtained. It is shown that the average value of the change in the probability of detecting flaws, which determines the value of the correction coefficient equal to 0.015 for flaws with a height of 4 to 12 mm (for the defectometry technique) and 0.18 for flaws with a height of 5 to 12 mm (for flaw detection techniques). For flaws less, than 4 mm in height, the average value of the change in the probability of detecting flaws for individual inspectors depends significantly on the height of the flaw. A significant difference in the average value of the change in the probability of detecting flaws and the standard deviation during inspection by flaw detection and defectometry techniques is associated with the difference in the amount of information provided by the inspection techniques and the individual characteristics of the inspectors.

Abstract: Chlorine is a green halogen-shaped halogen gas at normal temperature and serves as bleach, stain remover and disinfectant. Chlorine is now widely used for bleaching rice so that less quality rice looks like quality rice. Chlorine is very toxic and causes mucous membrane irritation, highly reactive and very powerful oxidizer. The purpose of this research was to determine the difference of chlorine level in chlorinated rice washed once, twice and 3 times. The sample in this study amounted to 11 samples calculated by replication formula. Each sample was treated 3 times, ie 1 washed once, 2 washed twice and washed 3 times. The samples then examined by iodometric titration method. Based on the results of the study using ANOVA test, 11 samples obtained the average value of chlorine after washed once amount of 0.0176%, after washed twice amount of 0.0111%, and after washed 3 times amount of 0.0052% with the value significance p = 0.03 (p <0.05) at 95% confidence level which means there was a significant difference between chlorine levels in chlorinated rice washed once, twice and 3 times.Abstrak: Klorin merupakan unsur halogen berbentuk gas berwarna kuning kehijauan pada suhu normal danberfungsi sebagai pemutih, penghilang noda maupun desinfektan. Klorin sekarang banyak digunakan untuk bahan pemutih beras agar beras yang kurang berkualitas tampak seperti beras berkualitas. Klorin sangat toksik dan menyebabkan iritasi membran mukosa, sangat reaktif dan merupakan oksidator yang sangat kuat. Tujuan dari penelitian ini ialah untuk mengetahui perbedaan kadar klorin pada beras berklorin yang dicuci sebanyak 1 kali, 2 kali dan 3 kali. Sampel dalam penelitian ini berjumlah 11 sampel yang dihitung dengan rumus replikasi. Setiap sampel diberi perlakuan sebanyak 3 kali, yaitu 1 kali pencucian, 2 kali pencucian dan 3 kali pencucian. Sampel penelitian kemudian diperiksa dengan metode titrasi iodometri. Berdasarkan hasil penelitian menggunakan uji Anova secara komputerisasi terhadap 11 sampel diperoleh nilai rata-rata kadar klorin setelah 1 kali pencucian sebesar 0,0176 %, setelah 2 kali pencucian sebesar 0,0111 %, dan setelah 3 kali pencucian sebesar 0,0052 % dengan nilai signifkansi p = 0,03 (p<0,05) pada tingkat kepercayaan 95% yang artinya ada perbedaan yang bermakna antara kadar klorin pada beras berklorin yang dicuci sebanyak 1 kali, 2 kali dan 3 kali.

The negative and persistent impact of the human factor on the statistics of aviation accidents and serious incidents makes proactive studies of the attitude of “front line” aviation operators (air traffic controllers, flight crewmembers) to dangerous actions or professional conditions as a key component of the current paradigm of ICAO safety concept. This “attitude” is determined through the indicators of the influence of the human factor on decision-making, which also include the systems of preferences of air traffic controllers on the indicators and characteristics of professional activity, illustrating both the individual perception of potential risks and dangers, and the peculiarities of generalized group thinking that have developed in a particular society. Preference systems are an ordered (ranked) series of n = 21 errors: from the most dangerous to the least dangerous and characterize only the danger preference of one error over another. The degree of this preference is determined only by the difference in the ranks of the errors and does not answer the question of how much time one error is more dangerous in relation to another. The differential method for identifying the comparative danger of errors, as well as the multistep technology for identifying and filtering out marginal opinions were applied. From the initial sample of m = 37 professional air traffic controllers, two subgroups mB=20 and mG=7 people were identified with statisti-cally significant at a high level of significance within the group consistency of opinions a = 1%. Nonpara-metric optimization of the corresponding group preference systems resulted in Kemeny’s medians, in which the related (middle) ranks were missing. Based on these medians, weighted coefficients of error hazards were determined by the mathematical prioritization method. It is substantiated that with the ac-cepted accuracy of calculations, the results obtained at the second iteration of this method are more ac-ceptable. The values of the error hazard coefficients, together with their ranks established in the preference systems, allow a more complete quantitative and qualitative analysis of the attitude of both individual air traffic controllers and their professional groups to hazardous actions or conditions.

The height of the maxillary alveolar ridge can be measured using panoramic radiography. The decline occurred because the height of the alveolar ridge undergoes slow physiological resorption due to the absence of mechanical stimulus. The purpose of this research is to know the difference and the average height of the maxillary alveolar ridge in edentulous and dentate women using panoramic radiography. This study is an analytical method with a cross-sectional approach. A total sample of 40 women, edentulous and dentate has been measured. Measurements were made by measuring the distance between the lowest point of the infraorbital ridge and alveolar crest maxilla on the incisor point, right and left premolar, right and left molar. A statistical test is done using independent t-test. The results showed that the average value of a dentate women sample is greater than edentulous. The average value obtained by the dentate sample is greatest in incisor point by 37,57mm± 3,34mm and the smallest at the right molar point by 33,87mm ± 2,81mm. The average value obtained by the edentulous sample is greatest in incisor point by 35,30mm ± 2,79mm and the smallest at the right molar point by 31,84mm ± 3,85mm. It can be concluded that there is a significant difference in the height of the maxillary alveolar ridge on an edentulous sample and dentate, except the right molar teeth. The average height of the maxillary alveolar ridge in an edentulous sample is 33,35mm ± 3,43mm, and the dentate sample is 35,66mm ± 3,21mm.

<p class="abstract"><strong>Background:</strong> Plantar fasciitis (PF) is considered as degenerative tendinopathies. Repeated micro trauma is the major etiology of these diseases. Autologous platelet rich plasma (PRP) injections are becoming more popular in the treatment of enthesopathies like PF. The growth factors in PRP cause tissue healing. We compared the result of injecting intra-lesional autologous PRP injections versus steroid infiltration in chronic PF.</p><p class="abstract"><strong>Methods:</strong> A prospective, interventional and analytic comparative study was done and 81 patients (120 heels) were included in this study and were followed up for 6 months. We assessed the outcome of each patient using visual analog score (VAS) and foot and ankle disability index (FADI) on follow-up at 1, 3, and 6 months. <strong></strong></p><p class="abstract"><strong>Results:</strong> In our study, female preponderance was seen. Left side was more common as compared to right side. Unilateral PF is more common than bilateral. The difference with in the individual group at baseline and at 1,3 and 6 months was statistically highly significant in terms of VAS and FADI (p=0.0001) But the difference in the between the two groups was insignificant for VAS and FADI at 1, 3 and 6 months.</p><p class="abstract"><strong>Conclusions:</strong> In our study, as there is no significant difference in VAS and FADI score between corticosteroid injection group and PRP injection group at 1, 3 and 6 months follow up. So, it’s reasonable to conclude that both are equally effective in PF. But as PRP injection comes out to be more time consuming and more costly, corticosteroid seems to be more efficient, cost and time wise. Hence, the latter should be a better choice.      </p>

Aim of the research was to find out and compare individual subsystems of selected types of aggressiveness and individual types of hostility within age categories of learners of sports hockey classes. Research sample consisted of sixth, seventh, eighth and ninth grade boys from primary schools. Age of learners varied from 11 to 14 years. Total sample consisted of 120 learners. The research was it was implemented with the help of a standardized psychological questionnaire B – D – I. In the results we‘re comparing the differences in individual subspecies of aggressive behaviour and also in overall aggressiveness between younger and older learners grade. It turned out that in all of the observed comparisons older learners achieved higher average values of the weighted score than younger. The difference was confirmed also by the nonparametric Mann Whitney U test, which at the unilateral test of 5 % level of demonstrability tells that between younger and older learners there‘s statistically significant difference p = 0.031. Also, any increased value of the resentment didn‘t occur neither among younger learners who achieved the average value of the weighted score 4.19 nor among older learners with the average value of the weighted score 4.81 and therefore there is not statistically significant difference (p = 0.681). Our research revealed that controlling emotions such as aggression is very important. Therefore, it‘s important to pay enough attention to the young athletes and their coaches to prevent any manifestations of aggressiveness from their performers and to encourage them to play fair-play sports.

AbstractUser involvement has become an explicit goal within social service provision. Even so, the term remains ambiguous, and its implementation troublesome. Implementation theory lists a number of factors influencing bureaucratic behaviour; in this paper we investigate the ‘human factor’. Our ambition is to provide a framework for analysis of user influence in activation programmes that includes the individual characteristics of both service users and service providers. Building on theoretical insights from the literature on activation and agency, we develop a framework that distinguishes between two ideal types of service users: Pawns and Queens, and two types of service providers: care-oriented Carers and rule-oriented Clerks. This framework is then applied to identify key challenges for the interaction between users and caseworkers in two challenging situations: when service users express little or no agency and when they express agency that is incompatible with the overall goals of the programme. We find that Carers show pronounced reluctance to overrule the choices made by service users even when they have conflicting views – and tend to postpone decisions when they interact with Pawns. Clerks tend to overrule the decisions of Queens when they have conflicting views, and to make decisions on behalf of Pawns. The analysis draws on data collected from 126 qualitative interviews with service providers and participants in the Norwegian Introductory Programme for immigrants and a survey of 320 caseworkers.

We have measured with positron emission tomography (PET) the regional distribution of extravascular lung water (EVLW) and hematocrit (HctL) in normal supine dogs. H2(15)O and C15O were used as total lung water (TLW) and intravascular water (IVW) compartment labels, respectively. An additional plasma volume label (68Ga-transferrin) was used to determine regional HctL. EVLW was calculated as the difference between TLW and IVW. In 13 dogs, EVLW was relatively constant along a gravity-dependent vertical gradient, although values in the most anterior regions were statistically less (P less than 0.05) than those in more posterior ones. The average value for EVLW (13 dogs) was 14.4 +/- 2.5 ml H2O/100 ml lung. When EVLW was compared with IVW on a regional basis, the EVLW/IVW ratio decreased significantly in a gravity-dependent direction from 1.95 +/- 0.28 to 0.88 +/- 0.18. In 7 dogs, no significant difference between HctL and systemic hematocrit (average ratio 1.01 +/- 0.08) was found nor was any significant variation of HctL within the lung detected. Thus, in contrast to gravimetric techniques, a hematocrit correction does not appear to be necessary when regional EVLW is studied by PET.

The paper analyzes the features of the formation of «model» budgets, assesses the consequences of the transition to the distribution of subsidies to the subjects of the Russian Federation from the federal budget on the basis of the calculation of the «model» budget and developed proposals for adequate consideration of the identified problems in the inter-budget policy of the Russian Federation. It is shown that the transition to the «model» budget in the Russian Federation is envisaged through the mechanism of redistribution of the total amount of subsidies to equalize the budget provision with simultaneous refinement of the method of increasing the allocated subsidies to the least affluent regions. The discrepancy between the current budget expenditures and the estimated need for budget allocations was revealed, which can lead to the emergence of unsecured budget expenditures for planned activities in a number of Northern and Far Eastern regions. The necessity for maximum orientation to the individual characteristics of the subjects of the Federation in the calculation of «model» budgets is shown, which is expressed in taking into account the rising cost factors associated with the uneven distribution of the population and the difference in the coefficients of transport accessibility in the subjects of the Russian Federation.

The article substantiates the main components of improving staff competencies in the face of change. It is determined that taking into account and combining "hard skills" and "soft skills" skills allow you to use the acquired knowledge to perform specific tasks in the workplace in a particular professional activity. Modern and traditional models, techniques and tools of personnel management are presented, according to which it is possible to clearly assess the difference in approaches to managing the competence of employees in the conditions of change. Based on the analysis of world practice, a list of methods is presented: discussions, brainstorming, Oxford debates, Case - Study, business and role - playing games, workshops, communication and management training, which are used to develop skills and abilities of employees. These methods allow expanding the educational opportunities of established forms of classes (lectures, seminars). The relationship between the acquisition of new and improvement of existing staff development competencies on the basis of training and coaching is shown. The proposed methods of acquiring competencies allow you to choose those competencies and methods of acquiring them that correspond to the individual characteristics of organizations. It is proved that the acquisition of competencies by staff allows identifying new competencies in employees, to form the need to use modern analytical and behavioral skills, providing greater opportunities for management skills and flexibility, dialectical thinking, ability to make creative decisions in unusual situations. It is substantiated that the combination of the SMART method in the acquisition of competencies significantly expands the possibilities of short-term learning, through the application of the concept of "lifelong learning". Different definitions of the essence of "competence" are analyzed, which allows emphasizing that when choosing different forms of education, in particular, trainings, different types of training it is necessary to use / apply modern methods and techniques. It has been proven that incompetent non-use by a staff of their knowledge, skills, experience and skills often leads to reduced profits and inefficient use of their potential.
