To meet or to connect? Face-to-face contacts vs ICT in cluster organisations
Authors: Lis Anna Maria , Lis Adrian 
Published: December 2019

Abstract
The main purpose of the paper is to explore how cluster organisations (COs) take advantage of direct (F2F) and indirect (ICT) contacts in fulfilling their main roles. The paper addresses the research question: “How important are Information and Communication Technologies at each level of advancement of cluster cooperation?” The research was conducted in 2016 in four purposefully selected cluster organisations representing metal and ICT industry. The basic method of data collection was an in-depth individual interview. The authors applied the qualitative content analysis as the procedure to analyse the interviews. The research sample comprised of 30 cluster members. The research was based on an original theoretical concept referring to the trajectory of the development of cooperative relationships in cluster organisations. Four levels of development of cluster cooperation as well as three main roles of cluster organisation were distinguished. At each level, COs play one of three identified roles: a direct resource supplier (providing access to resources), a broker (facilitating resource exchanges) and an integrator (integrating into different dimensions), which gives a total of 12 specific roles. The research has shown that both direct and indirect contacts were significant both in fulfilling the roles assigned to the cluster organisations as well as in developing the cluster cooperation. It has been also observed that ICT importance was slightly different at each level of a CO’s development. Only in one identified role (at level II: Process integrator) the importance of ICT tools was at least as great as F2F contacts. The research study contributes to the literature which refers to the question of face-to-face contacts established in geographical proximity versus the ones set up by using Information and Communication Technologies in cluster organisations. It was noticed that even though ICT plays a significant role in the functioning of COs, they cannot replace face-to-face contacts. They can only be their important complement at every level of CO development. There are also some limitations connected with the qualitative approach, which does not allow the author to generalise the findings. The first limitation is the small research sample. The second limitation is the subjectivity characterising qualitative research, mainly due to the applied techniques of data collection and analysis.

Abstract
The Ladislavci Field (oil and gas reservoirs) is located 40 km from the city of Osijek, Croatia. The oil reservoir is in structural-stratigraphic trap and Miocene rocks of the Vukovar formation (informally named as El, F1a and F1b). The shallower gas reservoir is of Pliocene age, i.e. part of the Osijek sandstones (informally named as B). The oil reservoirs consist of limestones, breccias and conglomerates, and gas is accumulated in sandstones. Using neural networks, it was possible to interpret applicability of neural algorithm in well log analyses, and using neural model, it was possible to predict reservoir without or with small number of log data. Neural networks are trained on the data from two wells (A and B), collected from the interval starting with border of Sarmatian/ Lower Pannonian (EL marker Rs7) to the well’s bottom. The inputs were data from spontaneous potential (SP) and resistivity (R16 and R64) logs. They were used for neural training and validation as well as for final prediction of lithological composition in the analysed field. The multilayer perceptron (MLP) network had been selected as the most appropriate.

Hidrogen merupakan salah satu sumber energi alternatif di masa depan. Penyimpanan Hidrogen dalam bentuk solid state memiliki keunggulan daripada penyimpanan dalam bentuk gas dan cair. Penelitian ini dilakukan untuk mempelajari pengaruh material MgAlTi dan temperatur aniling material (MgAlTi) hasil preparasi reactive mechanical alloying (RMA) terhadap sifat media penyimpan hidrogen. Penambahan paduan logam Al dan Ti pada paduan logam Mg dilakukan untuk memperbaiki sifat serapan Mg. Penelitian dilakukan dengan memadukan material Mg, Al dan Ti dengan komposisi berat berturut-turut 85, 15 dan 5 %. Ketiga logam dipadukan dengan teknik RMA. Persiapan pemaduan dilakukan dalam glove box yang dialiri gas argon untuk memastikan pengerjaan teknik RMA dalam keadaan inert. Pemaduan teknik RMA dilakukan selama 10 jam dengan dialiri gas Hidrogen. Selanjutnya, paduan Mg85Al15+Ti5 di anil dengan variasi temperatur pemanasan 300; 340; dan 380 °C. Karakterisasi struktur kristal, mikro dan termal uji diobservasi dengan menggunakan X-Ray Difraction, SEM-EDX dan Differential Scanning Calorimetry (DSC). Hasil analisis struktur kristal dan mikro sesudah di aniling menjadi homogen dan hasil ini menunjukkan bahwa temperatur optimum material penyimpan hidrogen terjadi pada temperatur 300 °C. Aktifitas katalis terhadap disosiasi ikatan Mg-H2 dapat menentukan penurunan temperatur desorpsi dibandingkan pengaruh temperatur aniling. Pemaduan teknik RMA pada paduan logam MgAlTi dapat meningkatkan sifat-sifat penyimpanan hidrogen.
Hydrogen is an alternative energy source and it has advantages to storage the element in form of solid state compare gas and liquid. The study was conducted to analyse the effect of MgAlTi in aniling temperature used reactive mechanical alloying (RMA) for hydrogen storage. The experimental was carried out to improve the absorption Mg by combination of Mg, Al and Ti materials with 85, 15 and 5% weight composition. The preparation is carried out in the glove box which is flowed with argon gas to ensure the work of the RMA technique in an inert state. The RMA techniques is carried out for 10 hours with Hydrogen gas flowing. Thus, the Mg85Al15 + Ti5 alloy is annealed with a heating temperature variation of 300; 340; and 380 °C. Characterization of crystal structure, micro and thermal tests were observed using X-Ray Difraction, SEM-EDX and Differential Scanning Calorimetry (DSC). The results of analysis of the crystal and micro structures after aniling become homogeneous and this shows that the optimum temperature of the hydrogen storage material occurs at a temperature of 300 °C. Moreover, the catalyst activity against dissociation of Mg-H2 bonds can determine the decrease in desorption temperature compared to the effect of aniling temperature. The integration of RMA techniques in MgAlTi metal alloys can improve hydrogen storage.

Authors: Vásquez Truissi Martha Lucía 
Published: December 2019

With this special number by the Colombia Médica journal, we wish to participate in the commemoration of the 65 years since the creation of the School of Nursing at Universidad del Valle. This journal, official organism of scientific diffusion at the University, joins this celebration to manifest recognition and gratitude to the founders, directors of the School and to the faculty staff who with their tenacity, vision, and sense of pertinence have contributed to placing this Academic Unit at the highest levels. There have been many contributions during these six and a half decades, but perhaps, one that gives us the most satisfaction is that of having been able to contribute to the high-level formation of human talent in nursing, not only at the local level but regionally, nationally, and internationally. The graduates from the different undergraduate and graduate programs can attest, through their outstanding professional performance, of this contribution to society. This supplement seeks to gather, besides the history of over half a century of our raison d’être in nursing, some of the paths that have been marking the perspective of the School. For this reason, we are presenting themes like disciplinary development in nursing, which reflects the multiple searches for the construction and projection of the exercise of the profession noting that the future raises complex and unavoidable challenges; likewise, the themes of student leadership and counseling make us encounter the tensions experienced on a daily basis as an institution dedicated to the formation of human talent in nursing, given that we are urged to reflect and join efforts to question ourselves critically on what type of human beings are being formed at the University and what society will be built with them. Finally, another path the School has been developing is the use of innovation and communications technologies. This has been one of the bastions that for over two decades have guided our teaching activities. In this supplement, we present the experience that has facilitated the formation in higher education of students with difficult access to classroom education because they have to comply with different roles in society, along with perspectives seen in this area. Readers will also find in this supplement, texts that address the field of research challenges in nursing and reflections on its social responsibility, as well as call to delve into the work process and its relationship with healthcare to permit analyzing the contributions from the different components in the health of nursing workers. Possibly, Reading this supplement will instigate readers’ thoughts, while contributing to solve some of their doubts, but surely and most importantly is that it will move them toward new challenges to think of and act in favor of nursing.

Aim. To study the anatomical and functional varieties of labial frenum and their prevalence in children aged 6–11 years in the territories of the Krasnodar Krai.Materials and methods. We have studied the prevalence of varieties of labial frenum anomalies in 120 children at the initial and fi nal periods of mixed dentition. A preventive examination of 60 children (1st observation group) and 60 children receiving orthodontic treatment (2nd observation group) at the children’s dental department of the Dental Clinic of the Kuban State Medical University was carried out. The criteria for inclusion in the observation groups were somatically healthy children, living in the city of Krasnodar, and the cities and areas of the Krasnodar Krai. Statistical analysis was performed using the Statistica 6.0 (StatSoft Inc., USA) software. Qualitative data were described using absolute values and percentages. To identify differences in the sign occurrence frequency between the groups under consideration, Fisher’s exact test was used due to the fact that the expected number of observations in the cells of the four-fi eld table was less than fi ve. The obtained value of the exact Fisher’s test p < 0.05 testifi ed to the absence of statistically signifi cant differences.Results. The prevalence of labial frenum anomalies reached 15% according to routine examination (1st observation group) and 20% — in children with dentoalveolar anomalies who applied for orthodontic treatment (2 observation group). No statistically signifi cant differences were observed between the groups of girls and boys by the prevalence of varieties of labial frenum anomalies (p > 0.05). In the 2nd observation group, labial frenum anomalies were detected 2 or more times more often (p < 0.05) in children living in cities (44.44%) and in the regions of the Krasnodar Krai, than in children living in the city of Krasnodar (21.43%).Conclusions. Anatomical and functional classifi cation refl ects the main varieties of the labial frenum and allows the indications for surgical intervention to be clarifi ed. An alteration trend of the attachment location of labial frenum to the gingiva was found due to the physiological increase in the dentoalveolar height in the jaw anterior parts during the eruption period of permanent teeth and the formation of their roots. In this regard, it is advisable to plan surgical intervention in the period of late mixed dentition taking into account the anatomical and functional variety of the labial frenum.

Aim. To identify patients with a high risk of precancerous diseases of the colorectal region for colonoscopy assignment in the practice of a district physician.Materials and methods. 122 patients were surveyed who underwent colonoscopy by the appointment of a district physician at the Municipal Polyclinic No. 3 in Tyumen. All examined patients were divided into two groups according to colonoscopy: with colon polyps — 64 (52.5 %) and without colon polyps — 58 patients (47.5 %).Results. The mean age of patients in the group with colon polyps was 59.8 ± 4.7 years, in the second group — 58.2 ± 4.8 years. In the group with colon polyps, more patients exhibited a low physical activity and poor nutrition compared to the group without colon polyps. Erosive gastritis and obesity prevailed in patients of the group with colon polyps as compared to the second group. The number of patients who smoked and drank alcohol prevailed in the group with colon polyps, in comparison with the second group. Patients with colon polyps were twice as likely to have a burdened hereditary history of colorectal cancer as those without colon polyps.Conclusion. Thus, the group of high risk of colon polyps included patients with risk factors: smoking, low physical activity and burdened hereditary history of colon cancer, as well as erosive gastritis in the history.
