    Opis:
    The following article aims to present the results of studies on the relationship of temperament, personality and organizational climate with the occurrence of OrganizationalCitizenship Behavior (OCB) in the organization. The study was qualitative, and correlational. The study group consisted of 42 activists in voluntary organizations aged from 18 to 19 years old, 15 men and 27 women. The following questionnaires were used: The scale measuring Organizational Citizenship Behavior (OCB) S. Retowski,Formal Characteristics of Behaviour - Temperament Questionnaire (FCZ-KT) B. Zawadzki and J. Strelau, PersonalityInventory NEO-PI-Costa Jr. and Mc'Crae Polish Adaptation and Organizational Climate Questionnaire by L. von Rosenstiel and R. Bögel – K. Durniat Adaptation. The study revealed a clear positive correlation with Organizational Citizenship Behavior (OCB) with a component of Agreeableness - Trust (A1), with Extraversion (E) and its components: Warmth(E1), Excitement Seeking (E5) Activity (E4) and Gregariousness (E2) and the component of Conscientiousness – Self-Discipline (C5), component of Openness to Experience – Actions (O4), and also negative correlations with Neuroticism (N) and its components: Vulnerability (N6), Self-Consciousness (N4) and Anxiety (N1). The study also revealed a clear positive correlationsOrganizational Citizenship Behavior (OCB) with Activity (AK), Endurance (WT) and Briskness (ĩW) and a clear negative correlation with Perseveration (PE), Emotional Reactivity (RE). In the group of volunteers there were also showed positive correlations of Organizational Citizenship Behavior(OCB) with a Career (Assessment and Promotion) (OA) and the Communication and Information (KI). Regression model developed using multiple regression (stepwise regression method) takes into account the following variables: Activity (AK - Temperament), Agreeableness component of the Personality - Straightforwardness (A2), and the component of Neuroticism – Self-Consciousness (N4), also the component of Conscientiousness – Deliberation (C6) and a component of Openness to Experience – Fantasy (O1) and the Organizational Climate subscale OA – Career (Assessment and Promotion). The obtained results indicate a strong relationship of personality and temperament variables and the organizational climate of the manifestation of Organizational Citizenship Behavior.

    Opis:
    The article presents a fragment of diagnostic research of a mixed nature, establishing the media reality of preschool children. It seeks answers to the question about the media reality of preschoolers in the opinions of children, teachers and parents. The diagnostic survey method (questionnaire, interview, document analysis) and statistical methods (chi-square test of independence, ANOVA, Phi coefficient, Cramer's V) were used. The study examined 100 6-year-old children, 100 parents and 16 pre-school teachers. It was established that: 1) pre-school children: have unlimited access to the mobile applications; they use media tools in an uncontrolled way at home; in kindergarten, they learn the rational and correct use of new technologies while playing and learning; 2) parents and teachers assess children's media competency at an average level; parents see advantages and disadvantages in the media usage by children; 3) children can independently install games on a tablet or smartphone, often their parents install them themselves (usually these are games inappropriate for children’s age); 4) there are significant differences between the opinion of children and the observations of parents regarding the use of media tools; preschoolers claimed that they use tablets more often, and parents most often indicated that the children mainly watch TV; 5) calculations of differentiating factors showed significant statistical differences only in one case – between teachers' opinion on the children’s level of media competency and the teachers’ degree of professional advancement; the higher the degree of advancement, the lower the assessment of the competency level represented by six-year-olds.

    Opis:
    The paper addresses an electro-chemical method called wet oxidation potential technique for determining the susceptibility of coal to spontaneous combustion. Altogether 78 coal samples collected from thirteen different mining companies spreading over most of the Indian Coalfields have been used for this experimental investigation and 936 experiments have been carried out by varying different experimental conditions to standardize this method for wider application. Thus for a particular sample 12 experiments of wet oxidation potential method were carried out. The results of wet oxidation potential (WOP) method have been correlated with the intrinsic properties of coal by carrying out proximate, ultimate and petrographic analyses of the coal samples. Correlation studies have been carried out with Design Expert 7.0.0 software. Further, artificial neural network (ANN) analysis was performed to ensure best combination of experimental conditions to be used for obtaining optimum results in this method. All the above mentioned analysis clearly spelt out that the experimental conditions should be 0.2 N KMnO4 solution with 1 N KOH at 45°C to achieve optimum results for finding out the susceptibility of coal to spontaneous combustion. The results have been validated with Crossing Point Temperature (CPT) data which is widely used in Indian mining scenario.
    W pracy omówiono możliwości wykorzystania metody elektro-chemicznej zwanej metodą określania potencjału utleniającego w procesie mokrym do określania skłonności węgla do samozapłonu. Dla potrzeb eksperymentu zebrano 78 próbek węgla z trzynastu kopalni w obrębie Indyjskiego Zagłębia Węglowego. Przeprowadzono 936 eksperymentów, w różnych warunkach prowadzenia procesu aby zapewnić standaryzację metody w celu jej szerszego zastosowania. Dla każdej próbki przeprowadzono 12 eksperymentów metodą badania potencjału utleniającego w procesie mokrym. Wyniki skorelowano z własnościami danego węgla przez przeprowadzenie badania petrograficznych i wytrzymałościowych parametrów węgla. Procedurę korelacji wykonano z wykorzystaniem oprogramowania Design Expert 7.0.0, następnie przeprowadzono analizę z wykorzystaniem sieci neuronowych w celu opracowania najkorzystniejszej kombinacji warunków eksperymentu do wykorzystania dla uzyskania optymalnych wyników. Badania wykazały, że najkorzystniejsze warunki dla procesu to zastosowanie roztworu 0.2 N KMnO4 z 1 N KOH przy 45°C dla uzyskania optymalnych wyników określania skłonności pokładów do samozapłonu. Walidację wyników przeprowadzono w oparciu o wyniki badania metodą określania temperatury przejścia (Crossing Point Temperature), szeroko stosowaną w przemyśle wydobywczym w Indiach.

    Opis:
    A series of Schiff’s base compounds were synthesized from 2,6-di(propan-2-yl) aniline with substituted aromatic aldehydes. The structures of all the synthesized compounds were characterized by physical constants, IR and NMR spectroscopic techniques. All the observed IR frequencies νC=N (cm-1), NMR δ(ppm) of C-H & C=N chemical shifts have been correlated with Hammett substituent constants and F and R parameters using single and multi-linear regression analyses in order to study the effect of substituents on these spectral data has been studied. All the synthesized Schiff’s base compounds were screened for their antimicrobial activity by disc diffusion method.

    Opis:
    The article presents part of a diagnostic and correlational study of mixed character that establishes pupils’ information competency in the use of ICT methods and tools. It investigates the effects of children’s and teenagers’ ICT use (importance levels of new media influence) on improving reflexes and manual coordination. To obtain the data, the author used a diagnostic survey method (questionnaire and interview) and statistical methods (chi-square test of independence and Pearson’s correlation coefficient). Together, 2,510 pupils and 1,110 teachers were surveyed. It was found that in the aggregated importance hierarchy of ICT effects, the category ‘reflexes and manual coordination’ was given a high weight by the pupils (third place) and a very high weight by the teachers (second place). There was a faint and negative correlation (r @ -0.009) between pupils’ opinions and teachers’ observations on the effects of ICT use by children and teenagers in the improvement of reflexes and manual coordination. The calculations of differential factors revealed statistically significant differences between the opinions of the two groups and gender, educational stage, place of learning and the gender of teachers. There was a noticeable discrepancy between the pupils’ and teachers’ opinions: a not very significant ‘separation’ of the world of children and teenagers (‘us’) from the world of teachers (‘them’). This may raise concerns as teachers’ recognition and understanding of students’ needs, according to the ideas of constructivism, is one of the key factors in the success of the educational process.
