Authors: Pacana Andrzej , Siwiec Dominika 
Published: October 2019

Abstract
The analyses of the nonconformity of products are made in order to achieve the desired level of their quality. This is also the case in the analyzed enterprise located in south-eastern Poland. Due to production character in this enterprise to identify the incompatibilities of products the non-destructive tests are used. In the current approach to quality after identified the nonconformities the cause her arise were determined, it was noted in order to use by statistical analyzes. Unfortunately, no deeper qualitative analyzes were made which could specify the source of its creation. Therefore, it was considered that it is necessary to propose to use (near current actions according to non-destructive tests) the sequence of quality management instruments. In order to improve the quality control actions, the sequence of techniques which complement each other, i.e. non-destructive tests, Ishikawa diagram and 5Why method, was proposed. To demonstrate the effectiveness of the proposed sequence, the rear cover of the bearing turbine was selected as the subject of the analysis. The choice was conditioned by the unit character of production, which till now was discouraged a detailed analysis of sources of nonconformities. After analyzed the product with used the fluorescent method the nonconformities were identified on the rear cover of the bearing turbine, which was the porosity cluster. In order to identify the causes these nonconformities the Ishikawa diagram was drawn up. Next, the selected main causes (i.e. supplier of the product and nonconformities created during the production of the product) were analyzed the 5Why method in order to identify the source cause of the problem. In this case, it was the nonconformity material from the supplier. The proposed sequence, which uses the minimal resources let to show the wide range of information, which should be used to the improvement of quality. The presented the set of activities can be practised in each of the enterprises to analyze quality problems in order to identify the nonconformities and their causes.

Published: October 2019

Abstract
The evaluation of the measurement system quality has already become an integral part of quality planning activities in both the automotive and metallurgical industries. An important assumption for obtaining the most relia ble results is compliance with the basic assumptions for evaluating the variability of the measurement system. The main goal of this paper is to analyze, how the failure to meet the basic assumptions influences the evaluation of the measurement system's statistical properties. This goal is achieved by performing a detailed analysis of the latest developments in the field of measurement systems analysis aimed at verifying the assumptions of normality and uniformity. The evaluation of the effect of non-fulfillment of both assumptions on the values of the most important statistical properties of the measurement system is performed using simulated data. Suitable graphical tools are used for practical verification of both assumptions.

Authors: Grznár Patrik , Mozol Štefan , Vavrík Vladimír , Gabajová Gabriela , Furmannová Beáta 
Published: October 2019

Abstract
In this article, it is described how the reconfigurable inter-operational buffers system built on the Digital Twin platform. Interoperating production buffers are now widely used in production. Their effect on the production system can be seen in decreasing downtime. From a cost-based point of view, the interoperating production buffers may generate a gain from the reduction in the volume of work-in-process, with which we increase production performance. This ratio depends on the average number of products that the buffers contain. The average number of pieces in the buffer is limited by the capacity of the buffer. The impact of turbulence in production is seen precisely on the average content of inter-operational production buffers. If we want to maintain work-in-process on optimal values, it is necessary to calculate and maintain the optimal capacity of each interoperating production buffer on the line. In the context of Smart Factory, it is currently possible that the current capacity of the interoperating production buffers is maintained according to the current state of production. In the subject system, real production facilities communicate with each other through the IoT as autonomous agents, which are decided on the basis of a formula to calculate the optimal capacity of the buffers, the prediction of faults and negotiation, thus actively maintaining the optimal capacity of intermediate operating production buffers for Smart Factory support.

Published: October 2019

Abstract

Introduction
This study aimed to characterise the effects of ketosis on milk yield and composition and digestive capacity in transition dairy cows.

Material and Methods
Seven ketotic and seven healthy cows were housed in individual stalls for six days. Samples of plasma, milk, refused total mixed ration, and faeces were collected, and the blood biochemical parameters, milk yield and composition, dry matter intake, and faecal dry matter (FDM) production were determined.

Results
Compared with healthy cows, the ketotic cows had significantly higher concentrations of milk fat and citrate, but lower levels of milk protein and lactose. The cows exhibited a need for acid detergent fibre in forage and better digestion of neutral detergent fibre, starch, crude protein, and phosphorus than healthy cows, but more fat and gross energy were excreted in their faeces. Ketotic cows had higher energy-corrected milk yields and lower FDM than healthy cows.

Conclusion
Lower feed intake coinciding with the requirement to maintain high milk production is considered to be the cause of ketosis in dairy cows. Ketotic cows exhibited lower dry matter fat digestion.
Where the geographical expanse ends – Space education in primary school. Implementation of inquiry based science education (IBSE) in geography lessons in Polish school
Authors: Sypniewski Jakub 
Published: October 2019

Abstract
Inquiry based science education has been more and more popular strategy in teaching sciences in recent years. Transregional pressure put by international, standardized knowledge and skills tests (e.g. PISA) to converge curricula (Rundgren 2015) of different European states paradoxically helps to promote the open inquiry method which involves the student in the teaching process. Earlier research done in many countries such as Turkey, Israel, Sweden, The Czech Republic (Heinz et al. 2017), Ireland (Dunne et al. 2013) or The Netherlands (Uum van Martina et al. 2016) shows the increase of interest in IBSE both in Europe and in the world.
Teaching geography in Polish primary schools follows international educational trends. This study analyses several proposals of educational activities connected with Space which support geography teaching. All of them are conducted with using open inquiry method, which is recommended in New National Curriculum of geography (Core Curriculum, 2017, Geography-classes V-VIII).

Authors: Freeman Maisha , Adunlin Georges A. , Mercadel Candice , Danzi Sara , Klein Irwin 
Published: October 2019

Purpose: Approximately 15% of patients with hypothyroidism are dissatisfied with their treatment due to persistence of residual symptoms associated with hypothyroidism. The purpose of this study was to compare thyroid symptoms using the hypothyroid symptom scale (HSS) in patients receiving stable thyroid therapy for 6 months to patients without hypothyroidism. The HSS was used to identify the percentage of levothyroxine-treated hypothyroid patients with residual or persistent hypothyroid symptoms.
Methods: Patients included in the study had hypothyroidism and were receiving a stable/maintenance dose of levothyroxine sodium therapy, unchanged for at least 6 months. A control group of patients were included if they did not have an active prescription for thyroid hormone therapy. The HSS was administered via phone or face-to-face interactions. Patients were asked to score 10 symptoms over the past month on a scale of 0 to 4 (e.g., 0, absence of, to 4, severe symptoms). Results were analyzed using descriptive and inferential statistics. T-tests and chi-squared analysis were used to assess differences in continuous and categorical variables.
Results: A total of 68% of the contacted patients responded to the survey. A total of 302 patients were in the intervention group and 273 were in the control group. The mean total HSS scores between groups were significantly higher in the treatment compared to the control group (13.92 ± 10.91 vs.10.07 ± 7.85; P < 0.001).
Conclusion: Significantly more patients receiving thyroid hormone therapy experienced residual thyroid symptoms compared to control patients. Attempts should be made to offer alternatives for hypothyroid patients with persistent symptoms.

La transparencia como principio vertebrador de la contratación pública: significado y problemas de articulación normativa
Authors: González Ríos Isabel 
Published: October 2019

El objeto de este trabajo es delimitar y concretar el significado del término transparencia aplicado a la contratación pública y despejar las dudas que plantea el sistema de fuentes con incidencia en la materia (la ley de contratos del sector público, la legislación de transparencia de 2013 y la ley de procedimiento administrativo común), proponiendo una interpretación integrada del mismo.
El concepto de transparencia en materia de contratación pública deriva de su configuración en el derecho de la Unión Europea como principio abstracto que favorece la buena gobernanza y la participación ciudadana, y que se orienta a lograr el mercado único. Pero su plasmación a nivel interno en varias normas con rango de ley exige clarificar las obligaciones que conlleva y su régimen de control, eliminando confusiones de articulación normativa.

Information ethics: why and how we teach the subject (Turkey)
Authors: Durukan Ayşe Yüksel 
Published: October 2019

School librarians have always strived to teach information ethics to students. The importance of conveying the concept of information ethics to students has become critical within the overwhelming effect of data and information flow. In an age of massive information flow we need to address the issues related to that subject: ethics vs. wrongdoing, propoganda vs. accuracy, bias vs. neutrality, prejudice vs. objectivity, self opinionatedness vs. flexibility, fiction vs. documentary, fact vs. opinion.
Turkish communities largely depend on oral culture. The codes of a written culture maybe unknown to some part of the population. In Turkey generally school librarians are not expected to teach. Most schools may not even have a certified librarian. Those who happen to work at schools are not expected to have a teaching certificate. Teachers at schools who speciliaze on subjects may teach about ethics, in case the issue is in question. Primary years programme has scheduled the subject Thinking in education which involves a chapter on citizenship and democracy education; the subject is offered as a elective. High school grades 10 and 11 will study philosphy but Being, Ethics, Art and Religion topics are undervalued. We as school librarians can fill in the gaps. We need to be role models in teaching media literacy, academic honesty and integrity, and above all the culture of information. Collaboration with teachers is a necessity, teaching information ethics related to the student lives, with direct examples drawn from their life- experiences are very important. If we teach the subject in a dull way, with irrelevant examples it makes no sense to them and they can easily disconnect. We need to adddress the issue of using text online, voice call, images and videos, the differences and similarities. We need to be information curators for our communities.
