Wizerunek i reputacja organizacji: informacyjny i zarządczy potencjał – część I
Authors: Wojcik Krystyna
Published: December 2021

Cel i tezy: celem artykułu jest zbadanie, czy i ewentualnie pod jakimi warunkami obecnie priorytetowy cel praktyki public relations – wizerunek – może służyć założeniom teorii PR mieszczącym się w stwierdzeniu „PR funkcją zarządzania organizacją”. Teza wyjściowa zakłada, że wizerunek jako komunikacyjne medium/przekaźnik i jednocześnie przekaz muszą charakteryzować bardzo określone cechy, tak aby PR mógł być wykorzystany jako funkcja w zarządzaniu organizacją. Koncepcja/metody badań: wiedza i studia literaturowe uwzględniające pozycje polskie i obcojęzyczne, w tym własne – z obszaru PR, komunikowania oraz zarządzania. Ze względu na typ kontaktów przydatny był – z zakresu teorii komunikowania – dorobek dotyczący komunikowania publicznego i instytucjonalnego, a z możliwych komunikacyjnych aspektów interpretacji tematu – aspekt instrumentalny. Wyniki i wnioski: wnioski są zawarte w dwóch hipotezach artykułu: (1) wizerunek/reputacja może służyć realizacji przez PR funkcji zarządzania organizacją pod warunkiem zasadniczego podniesienia wartości informacyjnej, w tym nacechowania wartościami wymaganymi przez teorię zarządzania strategicznego; (2) wymagałoby to zasadniczej reorientacji praktyki PR w zakresie podstawowego celu oraz profesjonalizacji zarządzania wizerunkiem. Wartość poznawcza/oryginalność: opracowanie ukazuje nowy problem naukowy, w zakresie zarówno celu, jak i hipotez. Identyfikuje zjawiska, mechanizmy i procesy kształtujące informacyjną wartość wizerunku/reputacji, analizuje kierunki potrzebnej reorientacji praktyki PR oraz najważniejsze korzyści, jakie w procesach zarządzania może dawać wykorzystanie wizerunki/reputacji. W swym głównym przesłaniu refleksyjnie nawiązuje do dwóch najbardziej znaczących paradygmatów w teorii public relations – teorii doskonałego public relations (gdy badamy, w jakim stopniu wizerunek w swym komunikacyjnym wyrazie może być użyty w doskonaleniu zarządzania organizacją, a przez to we wzroście efektywności organizacji) oraz relacyjnego public relations (gdy proponujemy zmianę celu wizerunkowego na relacyjny jako sposób podniesienia potencjału informacyjnego wizerunku/reputacji, a także gdy identyfikujemy bezpośrednie strategiczne korzyści z dobrych relacji z otoczeniem). Co więcej, wskazany problem badawczy jest konkretnym przykładem interdyscyplinarności nauki o komunikowaniu (jako dyscypliny z pogranicza m.in. nauk ekonomicznych, a w tych ramach zarządzania, marketingu i public relations).
Oglądając, słuchając, czytając – na co zwracamy uwagę?
Authors: Bloch Jagoda
Published: December 2021

Cel: artykuł dotyczy nierozłączności komunikacji werbalnej i niewerbalnej w przekazach medialnych, szczególnie telewizyjnych. Odbiorcy czerpią informacje z przekazów medialnych na podstawie tego, co widzą i słyszą w połączeniu z treścią, jaka do nich dociera. Ich uwaga jest więc podzielona na śledzenie różnych kanałów komunikacyjnych, a to oznacza, że część informacji może zostać pominięta. Aby sprawdzić, ile informacji może pozostać niezauważonych, zostało wykonane specjalne badanie. Metody badań: do badania wykorzystano nagranie jednego z orędzi noworocznych Prezydenta RP, a więc przekazu należącego do specyficznego gatunku mowy. Badanie polegało na rozwarstwieniu przekazu, a następnie sprawdzeniu, ile informacji jest zauważanych, gdy uwaga odbiorcy skierowana jest tylko na jeden kanał komunikacyjny: (1) na kanał wizualny, bez dźwięku; (2) na kanał audialny – bez obrazu; (3) na sam tekst orędzia. Badanie zostało przeprowadzone z zastosowaniem zogniskowanego wywiadu grupowego, metody często wykorzystywanej w celu uzyskania opinii względem danej kwestii. Wyniki nie stanowią zaskoczenia – okazuje się, że czerpanie informacji z kilku kanałów równocześnie dostarcza wielu informacji, jednakże dopiero rozwarstwienie kanałów pokazuje, ile nowych informacji dociera do odbiorcy, gdy jego uwaga skierowana jest na każdy z nich oddzielnie. Oryginalność/wartość poznawcza: badanie potwierdza intuicyjne przekonanie o zachowaniu uważności w odbiorze wszelkich treści medialnych. Ponieważ publiczne wystąpienia są częstą praktyką polityków czy ekspertów, należy być skupionym, by nie ulec fałszywym informacjom, czemu może sprzyjać tzw. szum informacyjny. Badanie służy również wykazaniu dużego znaczenia retorycznej zasady decorum dla tworzenia przekazów medialnych.

Published: December 2021

The research presented here studied preschool children’s representations of light. A teaching intervention was also carried out, with an aim to construct in children’s thinking a precursor model according to which light is recognized as an autonomous entity, which is independent of the light sources and the results it causes. The teaching intervention was conducted through the use of special software created in a scratch environment. The study, consisting of three phases (pre-test, teaching intervention and post-test), included 30 children aged 4-6 years. The results of the research showed that in the children’s initial mental representations light is identified mainly with light sources. After the teaching intervention, a large percentage of the children had constructed a precursor model which was compatible with the scientific one, based upon which children recognize light as an autonomous entity.

Published: December 2021

An observational instrument called the KTOP (Korean Teaching Observation Protocol) was developed to analyze science teaching and to identify the components of teaching that need improvement. To diminish the gap between theory and practice in science teaching, the method for developing the KTOP was structured as consisting of three steps: the first version of the KTOP was developed through direct observation of science classes at the first step, revised through literature review with consideration of the Korean national curriculum and comparison with other observational instruments in the second step, and finalized after application to actual teaching context. As a result, the KTOP was determined to consist of 30 items of 10 sub-categories in 4 main categories. The content was validated through 48 teachers’ responses to the questions asking if each indicator of the KTOP is worthwhile to be considered in their teaching. Reliability was obtained by agreement (72~90%) and correlation (r=0.90) among observers’ KTOP scores. Finally, the cases of applying the KTOP to improve science classes and to develop teachers’ expertise through an in-service program were described.
Key words: analysis of science teaching, improving science teaching, observational instrument, teacher’s teaching expertise.

Published: December 2021

Purpose. Assessment of the effectiveness of using the method of radio-wave geointoscopy of the inter-well space for three-dimensional mapping of the zone of the leaching solution actual propagation in the process of uranium mining by the method of underground leaching. Methods. Experimental-industrial studies of the leaching process are conducted at technological block 68 of the Semizbay deposit (Kazakhstan). In experimental studies, special equipment is used for conducting radio-wave geointoscopy. Inter-well measurements are performed using the RVGI-06 equipment. The observations are conducted in a fan pattern within the filter section. The step between adjacent points along the wellbore is 1 m. At different stages of mining the technological block, maps of geoelectric resistivity have been compiled, with the help of which a comparative analysis is performed. Findings. A tendency to an increase in the area of acidic solutions propagation over time has been revealed by comparing the fragments of RVGI geoelectric map at different stages of mining the block. The influence of a heterogeneous geological structure on the uniformity of the leaching solutions propagation has been proved. It has been determined that the resolving power of the radio-wave geointoscopy method is sufficient to detect changes in geoelectric conditions at small monitoring cycles in time. The spatial-temporal change in the front of the leaching solutions propagation makes it possible to determine the prevailing directions of solutions propagation and to assess the filtration characteristics of rocks. Originality. The patterns have been determined of the leaching solutions propagation over time from the beginning of block acidification to active leaching. The first attempts have been made to use the geophysical well logging method in the practice of uranium mining by In-Situ Leaching (ISL) method. Practical implications. Monitoring studies by radio-wave geointoscopy method at the stage of passive acidification can be re-commended for further experimental and scientific testing at technological blocks of the Semizbay deposit for a quantitative assessment of the filtration characteristics of rocks and the dynamics of the acidification process development, as well as for the development of well-grounded recommendations on the optimal scheme for mining the blocks in specific geotechnical conditions.
Interaction of rock-bolt supports while weak rock reinforcing by means of injection rock bolts
Authors: Krykovskyi Oleksandr , Krykovska Viktoriia , Skipochka Serhii
Published: December 2021

Purpose is to analyze changes in shape and dimensions of a rock mass area, fortified with the help of a polymer, depending upon the density of injection rock bolts as well as the value of initial permeability of enclosing rocks to substantiate optimum process solutions to support roofs within the unstable rocks and protect mine workings against water inflow and gas emission. Methods. Numerical modeling method for coupled processes of rock mass strain and filtration of liquid components of a polymer has been applied. The model is based upon fundamental ideas of mechanics of solids and filtration theory. The problem has been solved using a finite element method. Its solution took into consideration both the initial permeability and the permeability stipulated by mine working driving, injection time of reagents and their polymerization, and effect of po-lymer foaming in the process of mixing of its components. Changes in physicomechanical and filtration characteristics of rock mass during polymer hardening were simulated. It has been taken into consideration that a metal delivery pipe starts operating as a reinforcing support element only after the polymer hardening. Findings. If three and five injection rock bolts are installed within a mine working section then stresses, permeability coefficients, pressure of liquid polymeric composition, and geometry of the fortified area of rock mass have been calculated. It has been shown that rock bolt location is quite important to form a rock-bolt arch. It has been demonstrated for the assumed conditions that if five injection rock bolts are installed within the mine working roof then close interaction between rock-bolt supports takes place; moreover, the integral arch is formed within the mine working roof. Originality. Dependence of change in the polymer reinforced area upon a value of initial permeability of enclosing rocks has been derived. It has been shown that in terms of low values of initial permeability, geometry of rock-bolt supports as well as its size is identified only by means of a value of the unloaded zone around the mine working. In this context, initial permeabi-lity increase results in the enlarged diameter of the reinforced rock mass area in the neighbourhood of the injection rock bolt. Practical implications. The findings are recommended to be applied while improving a method to support the mine working roof and decrease water inflow as well as gas emission from the rocks, being undermined, into the working.

Published: December 2021

Purpose. The purpose is to reduce mineral losses during the explosive destruction of rocks and environmental pollution by harmful gases and fine particulate matter. Methods. To achieve the objectives of the study, methods of physicochemical analysis and mechanics of continuous media have been used. The method of physico-chemical analysis has been used to determine the quantitative and qualitative characteristics of the composition of the well stemming depending on the parameters of the well, the type of explosive, the amount and type of harmful gases formed during the explosion. Methods of solid medium mechanics have been used to establish the patterns of pressure waves during an explosion depending on the characteristics of the gap filler between the charge and the well wall. To solve the problem of the behavior of a two-layer medium during the loading of a cylindrical cavity by a nonstationary load, a numerical method based on the finite-difference McCormack predictor-corrector scheme has been used. Findings. A resource-saving and environmentally friendly charge structure for rock mining by explosion was developed. The design of the charge involves the formation of a gap between the charge and the wall of the borehole, and filling it with a suspension of calcium hydroxide or a suspension of calcium carbonate. Originality. SThe dependences of the volume of harmful gases (NO2, CO2, CO) formed during the explosive destruction of rocks and the magnitude of the pressure peak in the area close to the charge on the chemical composition of the filler of the radial gap between the charge and the well wall have been set. Practical implications. Developed charge design allows to neutralize the harmful gases formed during the explosion, to reduce the pressure peak in the area of the rock massif close to the charge, and can be widely used in non-metallic quarries that extract minerals for the production of crushed stone.

Methods. An integrated approach is used, which includes a critical analysis of literature data on the occurrence and development of coal aerosol explosions in mine workings; theoretical research into the state of the gaseous medium at the characteristic points of the development diagram of the coal dust deposits explosion as a result of mining operations based on the laws of classical physics and chemistry. Findings. The main aspects of the explosion mechanism of dust in a powdery state, accumulated on the surfaces along the mine working perimeter, and the formation of such negative factors as the effect of gaseous medium accelerated movement, have been revealed; high temperature formed during coal and methane detonative combustion; increased gas pressure. The revealed aspects of the dust explosion mechanism make it possible to determine the main directions for protection of miners caught in the explosion. The diagram of the development of settled coal dust explosion along the mine working with normal ventilation conditions, taking into account the influence of seismic waves, has been improved. Originality. Analytical dependences, reflecting the value of gas energy at characteristic points of the diagram, have been determined, and the dynamics of the formation of negative factors caused by the explosion have been revealed. Practical implications. Possible ways of protecting miners from the impact of negative factors caused by the coal aerosol explosion and reducing the severe consequences of such accidents are proposed.

Of which, 30(50%) were tuberculous meningitis (TBM) taken as cases and rest 30(50%) were non-tuberculous meningitis (NTBM) taken as control.The CSF ADA activity from TBM patients was compared with CSF ADA from non-TBM infectious meningitis patients. The mean CSF ADA activity was found to be significantly higher in CSF of TBM patients, 14.01 ± 12.4 (1.0–65.2), mean ± SD with range, than in the CSF from non-TBM infectious meningitis, 7.2 ± 8.2 (1.8–49.1) P = 0.01.A cut-off value of >7.6 U/L for the TBM patients was calculated from the mean ±SD of the non-TBM patients.The ADA sensitivity is 81.82%,specificity 65.31%,accuracy 68.33%, PPV 34.62%,NPV 94.12%, positive likelyhood ratio 2.3 and lastly negative likelyhood ratio 0.2 for infectious TBM when this cut-off value was used.ROC curve shows area under curve of .736 suggests a moderate accuracy of the test in detection of tuberculous meningitis.

Conclusion: This study demonstrated that ADA activity in the CSF of TBM patients, using a cut off value 7.6 U/L, can be useful for the early differential diagnosis of TBM. This test can be performed in any pathology laboratory where more sophisticated methods are not available.

Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular condition characterized by proximal and distal muscle wasting, weakness, fasciculation. The etiology of the disease is unknown. The annual incidence rate is one to two cases per 100,000 persons. The disease is most commonly presents in middle age, mostly after the age of 50 and very uncommon before the age of 30 years and affects men more than women. Usually it present with limb muscle weakness, cramps, occasionally fasciculations and sometimes with dysarthria, dysphagia. Symptoms often begin focally in one part and spread gradually but relentlessly to become widespread. Over a period of months or years, patients with ALS develop severe, progressive muscular weakness and other symptoms caused by loss of function in both upper and lower motor neurons. Sphincter control, sensory function, intellectual abilities and skin integrity are preserved. Patients become completely disabled, often requiring ventilatory support and gastrostomy. Death usually occurs within five years of diagnosis and is attributed to respiratory failure or cachexia. Current management involves aggressive, individualized alleviation of symptoms and complications. We are reporting an 18 year old right handed male presented with typical features of ALS . The purpose for reporting was for its rarity before 40 years and that had a typical clinical features of young-adult ALS, and to compare them with features of the common adult-onset type.

Vegetables are major source of vitamins and fibers but presence of pathogens in salad vegetables can cause outbreak of diseases. Several studies have been conducted on commonly consumed vegetables so far to detect the level of microbial contamination. However, few of them compare the microbial quality of local and super shop vegetables. The present study was conducted for microbiological assessment and comparing four types of vegetables collected from two different market conditions. In this study, Green chili (Capsicum frutescens L.), Tomato (Solanum lycopersicum), Coriander (Coriandrum sativum) and Lady’s finger (Abelmoschus esculentus) were analyzed to determine Total Viable Bacterial (TVB) Counts, Total Fungal (TF) Counts, Total Coliform Counts (TCC), Total Fecal Coliform (TFC) Counts and occurrence of Staphylococcus aureus, Pseudomonas spp., Listeria spp., Bacillus spp., Salmonella spp., and Vibrio spp. Among these microorganisms, Klebsiella spp. and Pseudomonas spp. were significantly present in coriander of both local market and super shop. All pathogenic bacteria and fungi were found in huge amounts in the vegetable samples of the local market. Although some pathogenic bacteria and fungi were also found in the same samples of the super shop, relatively lower than the local market’s vegetables. In conclusion, contamination in collected vegetable samples were not acceptable but comparatively higher load in local market samples indicated that the hygienic condition in these markets is not sufficiently maintained.

Published: December 2021

Introduction: Phyllodes tumors are fibroepithelial breast lesions that are uncommon in women and rare among children. Due to scarcity, there are only a few large pediatric phyllodes tumor series. Current guidelines do not differentiate treatment recommendations between children and adults.Case Presentation: A 12-year-old girl presented with a lump in her right breast which grew rapidly within a month. On physical examination, we found a mass on the right breast sized ± 10 x 10 cm; the lump was fragile and bled easily. The patient’s condition was getting worse and worse. Due to this deterioration, we performed a mastectomy immediately.Conclusions: The incidence of malignant phyllodes tumor in children is very rare and required prompt treatment in emergency cases.
Role of Autologous Fibrin Glue (AFG) to Reduce Drainage Volume After Modified Radical Mastectomy for Breast Cancer

Published: December 2021

Background: Seroma is arguably the most significant complication that can happen after mastectomy. Although seroma is not a life-threatening complication, this condition can lead to severe morbidities. This situation can cause prolonged hospital stays and delayed adjuvant therapy. In this regard, autologous fibrin glue is a hemostatic agent that can accelerate fibrin formation, stop vascular oozing, and decrease dead space. Therefore, this research was performed to evaluate autologous fibrin glue function in lowering seroma volume after mastectomy and shortening the length of hospital stay.Methods: This randomized control trial research was designed to compare the effect of autologous fibrin glue to a control group that did not receive autologous fibrin glue. Seroma volume was calculated every 24 hours. The drains were then removed after the production of seroma less than 30 mL/24 hours.Results: We recruited 20 patients for each of the two groups who met the inclusion criteria. Age, histopathology type, breast cancer stage, number of lymph nodes, and tumor size did not significantly differ. However, patients in the fibrin glue group had significantly lower cumulative drain production. The median seroma volume in the treatment group was 9.30 mL, while the median in the control group was 20.90 mL (p < 0.05).Conclusions: Autologous fibrin glue significantly decreased seroma formation and length of hospital stay.

Published: December 2021

Introduction: Leiomyosarcoma (LMS) is a fatal tumor, though primary cardiac is very rarely encountered. In this report, we evaluated the surgical and medical management of primary cardiac LMS, which is a sporadic tumor.Case Presentation: A 60-year-old female patient was examined for pulmonary edema after penicillin allergy in May 2019, while transthoracic echocardiography (ECHO) revealed an appearance compatible with a 5x3.5 cm mass in the right atrium. In addition, transesophageal ECHO showed a 7x4.6 cm foreground mass compatible with a myxoma in the right atrium (RA). The patient was then operated on emergency. Besides, an adjuvant ifosfamide-mesna-doxorubicine (IMA) protocol was planned to be given to the patient after local radiotherapy.Conclusions: In this report presented, we made RT and chemotherapy treatment plans in the case of recurrence without R0 surgery. Recurrence rates of up to 50% can occur in LMS, and systemic chemotherapy can be applied after relapse

The study was conducted in the river system located at Wilmar oil palm plantation in Miri, Sarawak. The objective of the study is to determine the fish species diversity and composition in the streams and rivers in the oil palm plantations. Fish were sampled using a variety of fishing methods, including, scoop nets, cast net, and gill nets of different mesh sizes (1.0, 1.5, 2.0, 2.5, 3.75 and 4.0 cm) from 2 to 7 of February 2014. A total of 326 individual fish including 32 species of native fishes and one species of non-native fish from 19 genera, seven families and five orders were collected from seven locations. The cyprinid fish represented 62.20% of the total fish caught and was found in all the rivers surveyed. About six endemic species in Borneo such as Barbonymus collingwoodii, Barbodes banksi, Barbodes sealei, Hampala bimaculata Nematabramis borneensis and Nematabramis everetti were identified. However, only one species from families Bagridae, Balitoridae, Clariidae, and Hemiramphidae was sampled from the study sites. The higher fish species composition found in streams and rivers of the oil palm plantation landscapes could be attributed to the conservation of some areas of the plantation as high conservation value forest (HCVF) status, which have provided suitable habitat for fish species within the plantation aquatic environments.
