Implementing activities within the framework of logistic and marketing functions and their influence on their level of integration
Darja Topolšek, 2010, izvirni znanstveni članek

Opis: Activities which are implemented in logistic and marketing function often intertwine or overlap in practice, what can often lead to double implementation. Within the framework of this article we will analyse the actual state of implementing activities in companies in correlation with the functional area. Logisticians often define integration within the frame of the aforementioned chain, yet they neglect the internal integration or the integration of particular departments or particular functions in the company. Defining internal integration and its level as well as the connection with the index of the actual implementation of activities is the basis of the research part of this article. The quantitative research part studies whether and to what extent the implementation of activities influences the level of internal integration between the logistic and marketing function. Research is based on quantitative analysis of results which were gained from the questionnaires and were filled out in Slovenian retail companies.

Do women see things differently than men do?
Norbert Jaušovec, Ksenija Jaušovec, 2009, izvirni znanstveni članek

Opis: The aim of the study was to investigate the influence of gender on brain activity. Thirty male and 30 female respondents solved simple auditory and visual tasks while their electroencephalogram (EEG) was recorded. Also recorded was the percentage of oxygen saturation of hemoglobin (%StO2) in the respondents' frontal brain areas with near-infrared spectroscopy (NIRS). The attended task condition was based on the oddball paradigm. Respondents had to mentally count infrequent target stimuli - tones or shapes. In the unattended condition they just listened to tones or viewed different shapes. Gender related differences in EEG activity were only observed in the amplitudes of the early evoked gamma response and the P3 component. Women displayed higher amplitudes than men. A second finding was that these differences were more pronounced for the visual than for the auditory stimuli. No gender related differences were observed in the ERP latencies, as well as in the amplitudes of the P1-N1 complex, and the induced gamma response. The NIRS data showed that males in their frontal brain areas displayed a higher percentage of StO2 than did females; and males also showed a higher increase in %StO2 during task performance as compared with the resting condition. Taken all together the results suggest that the females' visual event-categorization process is more efficient than in males. The data are discussed in the theoretical framework of the evolutionary theory of human spatial sex differences.

Gender related differences in visual and auditory processing of verbal and figural tasks
Norbert Jaušovec, Ksenija Jaušovec, 2009, izvirni znanstveni članek

Opis: The aim of the present study was to investigate gender related differences in brain activity for tasks of verbal and figural content presented in the visual and auditory modality. Thirty male and 30 female respondents solved four tasks while their electroencephalogram (EEG) was recorded. Also recorded was the percentage of oxygen saturation of hemoglobin (%StO2) in the respondents' frontal brain areas with near-infrared spectroscopy (NIRS). The main findings of the study can be summarized as follows. (1) Most pronounced differences between males and females were observed for the factor modality-visual/auditory. (2) Gender related differences in neuroelectric brain responses could be observed during the solution of auditory and visual tasks; however, on the behavioral level only for the visual tasks did females display shorter reaction times than males. The ERP amplitudes of the early evoked gamma response, P1, and P3 were higher in females than males, whereas the N4 amplitude was higher in males than females. The differences were more noticeable in the visual modality. The NIRS showed a more bilateral involvement of the frontal brain areas in females as compared with a more left hemispheric frontal activity in males. In the task conditions an increase in right hemispheric activity in females was observed; however, this increase was less pronounced in the visual than the auditory domain, indicating a more lateralized processing of visual stimuli in females. Taken all together the results suggest that the females' visual event-categorization process is more efficient than in males.

MLC-kinase/phosphatase control of Ca[sup]2+ signal transduction in airway smooth muscles
Aleš Fajmut, Milan Brumen, 2008, izvirni znanstveni članek

Opis: In airway smooth muscles, kinase/phosphatase-dependent phosphorylation and dephosphorylation of the myosin light chain (MLC) have been revealed by many authors as important steps in calcium ▫$(Ca^{2+})$▫ signalling pathway from the variation of ▫$Ca^{2+}$▫ concentration in cytosol to the force development. Here, a theoretical analysis of the control action of MLC-kinase (MLCK) and MLC-phosphatase (MLCP) in ▫$Ca^{2+}$▫ signalling is presented and related to the general control principles of these enzymes, which were previously studied by Reinhart Heinrich and his co-workers. The kinetic scheme of the mathematical model considers interactions among ▫$Ca^{2+}$▫, calmodulin (CaM) and MLCK and the well-known 4-state actomyosin latch bridge model, whereby a link between them is accomplished by the conservation relation of all species of MLCK. The mathematical model predicts the magnitude and velocity of isometric force in smooth muscles upon transient biphasic ▫$Ca^{2+}$▫ signal. The properties of signal transduction in the system such as the signalling time, signal duration and signal amplitude, which are reflected in the properties of force developed, are studied by the principles of the metabolic control theory. The analysis of our model predictions confirms as shown by Reinhart Heinrich and his co-workers that MLCK controls the amplitude of signal more than its duration, whereas MLCP controls both. Finally, the simulations of elevated total content of MLCK, a typical feature of bronchial muscles of asthmatic subjects and spontaneously hypertensive rats as well as potentiation of MLCP catalytic activity, are carried out and are discussed in view of an increase in the force magnitude.

Spatial rotation and recognizing emotions : gender related differences in brain activity
Norbert Jaušovec, Ksenija Jaušovec, 2008, izvirni znanstveni članek

Opis: In three experiments, gender and ability (performance and emotional intelligence) related differences in brain activity - assessed with EEG methodology - while respondents were solving a spatial rotation tasks and identifying emotions in faces were investigated. The most robust gender related difference in brain activity was observed in the lower-2 alpha band. Males and females displayed an inverse IQ-activation relationship in just that domain in which they usually perform better: females in the emotional intelligence domain, and males in the visuospatial ability domain. A similar pattern of brain activity could also be observed for the male/female respondents with different levels of performance and emotional IQ. It was suggested that high ability representatives of both genders to some extent compensate for their inferior problem solving skills (males in emotional tasks and females in spatial rotation tasks) by increasing their level of attention.

Human resource development in a small company
Mojca Bernik, Dušanka Kermc, 2013, izvirni znanstveni članek

Opis: The small business sector is often overlooked in human resource development researches, despite representing a large portion of the total economy. Very few studies exist on the subject of human resources development needs analysis in small organisations. Development plans remain mostly unwritten, which can lead to the impression that development is not being implemented or planned and is therefore not valid. This paper presents case study of the existing human resource development system in a small company PAN -JAN d.o.o. The research included 80% of all employees, which is 20 out of 25. The research examined the correlation between the additional education and better business performance, analysis of variance on age and number of courses and discriminant analysis on age, years of service, levels of education and legally required education and training programmes. In discussion are proposed changes or improvements, as well as a human resource development model.

The Decision support system for supplementary activies on organic farms
Karmen Pažek, Črtomir Rozman, 2007, izvirni znanstveni članek

Opis: In this paper we present the decision support system for ranking food processing projects on organic farms. The system is based on simulation modeling and multi criteria decision analysis. The deterministic simulation system KARSIM EKO 1.0 (DSM) consists out of deterministic production simulation models that enable different types of costs calculations for organic production and on farm food processing in the framework of supplementary activities. Simulation models results were further evaluated using a qualitative multi-attribute modeling methodology, supported by the software tool DEX-i and quantitative analytical hierarchical process - AHP, supported by Expert Choice 2000 TM software. The analysis showed that by using current model input parameter the combination of apple cider, apple vinegar and plum brandy (business alternative 1) results with the best multicriteria evaluation (EC=0,413 and DEX-i evaluation = very good).

Preschool teaching staff 's opinions on the importance of preschool curricular fields of activities, art genres and visual arts fields
Tomaž Zupančič, Matjaž Mulej, Branka Čagran, 2015, izvirni znanstveni članek

Opis: This article presents preschool teachers’ and assistant teachers’ opinions on the importance of selected fields of educational work in kindergartens. The article first highlights the importance of activities expressing artistic creativity within modern curriculums. Then, it presents an empirical study that examines the preschool teachers’ and assistant teachers’ opinions on the importance of the educational fields, art genres, and visual arts fields. In research hypotheses, we presumed that preschool teachers find individual educational fields, individual art genres, and individual visual arts activities to be of different importance; consequently, education in kindergarten does not achieve the requisite holism. The study is based on the descriptive and causal-non-experimental method. We have determined that the greatest importance is attributed to movement and language, followed by nature, society, art and mathematics. Within art genres, the greatest importance is attributed to visual arts and music and the least to audio-visual activities. Within visual arts, drawing and painting are considered to be the most important and sculpting the least. These findings can support future studies and deliberation on the possible effects on practice in terms of requisitely holistically planned preschool education.
