Published: March 2021

A szerző több mint 15 éve tanít a kolozsvári Babeș-Bolyai Tudományegyetem Közgazdaságés Gazdálkodástudományi Karának magyar tagozatán, s ez lehetőséget nyújt az ottani és a hazai közgazdászképzésben szerzett tapasztalatok összevetésére. Ebben a tanulmányban arra a kérdésre keressük a választ, hogy milyen tényezők járultak hozzá a kolozsvári magyar nyelvű közgazdászképzés sikereihez. Ezekről a sikerekről egyrészt a nemzetközi vállalati esettanulmány versenyeken elért eredmények tanúskodnak másrészt a végzett hallgatók karrierútjai. Szemügyre véve az oktatók tevékenységét, a tanulmány fő következtetése az, hogy a sikerek hátterében az egyetem falain túlmutató, sokrétű, intenzív kapcsolati háló húzódik meg, mely az egyetemen folyó képzést összekapcsolja a középiskolákkal, a vállalatokkal, az egyetemen kívül működő diákszervezetekkel, valamint a külföldi társintézményekkel. A számos irányban fenntartott, sokrétű kapcsolatrendszer működtetésének szemügyre vétele a hazai közgazdászképzés színvonalának emelése szempontjából is fontos tanulságokat hordoz.

Published: March 2021

BACKGROUND India has plenty of sunshine, yet people here are deprived of vitamin D – ‘sunshine vitamin’. According to endocrine society of India, vitamin D levels of < 20 ng / mL is considered to be vitamin D deficiency. The objective of the study was to evaluate seasonal variation of vitamin D and give an insight on risk factors such as age, gender, diet, body mass index, occupation, skin complexion and body surface area exposure on vitamin D level. METHODS The study was conducted in a tertiary hospital in Mangalore on 109 apparently healthy individuals. The same cohort of subjects was followed for two seasons - summer and winter. Serum was collected and analysed for 25-OH vitamin D, calcium and phosphorous. Skin color was assessed according to the Fitzpatrick classification, questionnaire was given to assess the approximate time limit of sun exposure in a day along with the exposed areas to sunlight and anthropometric parameters such as height and weight were measured using standard guidelines. Body mass index (BMI) was calculated. Comparison of mean vitamin D along with the factors influencing them in both seasons was done using paired t test. Inferential statistical analysis was done using chi-square test. Pearson correlation test was also done. Statistical significance was considered at P < 0.05. RESULTS Mean vitamin D was higher in summer (15.14 ± 5.62) as compared to winter (14.42 ± 5.38) irrespective of the risk factors. Vitamin D deficiency was highest in older age group (83.9 %), females (84.6 %), overweight (100 %), vegetarians (92.3 %), office workers (91.2 %), both complexions and those exposed with < 1.5 hours of sunlight (97.2 %). Vitamin D deficiency was also more prevalent in those with lesser exposed body surface area. CONCLUSIONS Vitamin D deficiency was statistically most common in winter than summer. It was seen correlating with majority of the risk factors, except skin complexion and among the confounding factors. The key for vitamin D production in this population was maximum body surface area exposure (face, hand, leg and feet) to sunlight for more than 2.5 hours, yet these subjects were vitamin D deficient. However, they did not manifest with any skeletal or extra-skeletal morbidity. Thus, concluding that a reliable cut off value for reference range of vitamin D should be set in this population in order to abstain from excess vitamin D treatment.

Non-Fluoridated Remineralising Agents - A Review of Literature
Authors: Batra Akriti , Shetty Vabitha
Published: March 2021

Dental caries is not merely a continuous and one-way process of demineralisation of the mineral phase, but repeated episodes of demineralisations and remineralisation. The remineralisation process is a natural repair mechanism to restore the minerals again, in ionic forms, to the hydroxyapatite (HAP) crystal lattice. It occurs under nearneutral physiological pH conditions whereby calcium and phosphate mineral ions are redeposited within the caries lesion from saliva and plaque fluid resulting in the formation of newer HAP crystals, which are larger and more resistant to acid dissolution. An insight into the caries process’s multifactorial aetiopathogenesis has resulted in a paradigm shift towards minimally invasive dentistry. This era of personalised care using the medical model for caries management assimilates the signs of examining, diagnosing, intercepting, and managing dental caries at a microscopic level. Fluoride mediated salivary remineralisation system is considered the cornerstone of non-invasive approach for managing non-cavitated carious lesions. However, the effect of fluoride was found to be limited to the outer surface of the tooth, and it was observed that fluoride does not influence the modifiable factors in dental caries such as the biofilm. Hence, fluoride does not reduce the cariogenic challenge especially for high-risk individuals. Due to this gap in the conventional fluoride therapies, non-fluoridated remineralising systems have emerged, which interact with the tooth by delivering calcium and phosphorous ions, modifying the biofilm and neutralising the organic acids. This review re-examines the philosophy behind non-fluoridated remineralisation, their mode of action, availability in the market and evidence-based studies of the most promising advancements in remineralisation approaches.

Estimating Collaboration through Variation in Time Series from Members in Group Works
Authors: Hattori Yuto , Harada Fumiko , Shimakawa Hiromitsu
Published: March 2021

In successful group works, members engage in monitoring where they guess what other members are thinking. Since monitoring promotes self-regulated learning, many teachers try to introduce group works.

This paper proposes a method to inform teachers on the fly of the monitoring status of students in group works using inexpensive and less invasive sensors. In the field of education, the method enables a teacher who supervises many student groups to direct their group works to successful ones.

The method collects accelerations of multiple body parts and pulse waves from each member using sensors. The method uses the singular spectral transformation (SST) to detect the relative changes of each signal in the course of time. When a significant change takes place, it is considered the members get arousal. The method considers group members engage in monitoring when significant changes appear simultaneously among them.

In an experiment to detect successful discussion to integrate ideas from the members into one feasible solution, we have obtained the accuracy of over 0.7. It indicates that the simultaneity of significant changes detected by SST is effective to estimate the monitoring state. In the experiment result, acceleration often worked better than pulse wave signals. It was also found that each member has a different role in the group. The behavior of each member varies with the role of the member. These results show that the method has potential to estimate the monitoring state. They also imply examination of the acceleration of each body parts would enable us to estimate the role of the members. The method allows one teacher to lead many groups to successful group works.

Wartime Sexual Acts as Prosecutable War Crimes
Authors: Oikya Upal Aditya
Published: March 2021

Human history is littered with the mass rape of women particularly as a military strategy in warfare, dating back centuries from ancient Greek, Roman, and Hebrew concubines through the Middle Ages to the 20th century ‘comfort women’ of the 2nd World War. Ancient literature explicitly refers to rape or the seizure of vanquished women, who were regarded as the enemy’s property, to become wives, servants slaves, or concubines. The plight of women worsened in the twentieth century when civilian women suffered the most consequences of armed conflicts including rape. Rape served as an oppressive and humiliating tool to severe family identity to dominate, demoralize, and destroy the entire enemy society and way of life. In the past, there appeared to be no international law that specifically dealt with rape in armed conflicts. This was caused by the ambivalent relationship between the law of armed conflict and gender-based crimes. Rape was overlooked as an unfortunate yet inevitable by-product of war. Both international humanitarian and human rights laws did not initially recognize rape as a serious war crime and a fundamental breach of human rights. This deafening legal silence and gap are being addressed through an ongoing evolutionary process by criminalizing wartime predatory sexual acts as a war crime, crimes against humanity, and even genocide. However, with the developments of international law and its practice, for the first time in the history, mass rape and sexual enslavement in the time of war be regarded as ‘crimes against humanity’ in a landmark ruling from the Yugoslav War crime tribunal in the Hague on 22 February 2001. But, even before that, some prior legal instruments for example the Lieber Code, promulgated during the American Civil War regarded [wartime] rape as war crime with capital punishment. Thus, this paper aims to analyze how the historical legal instruments have articulated the extend of criminality and culpability of wartime rapes and other sexual violence and their nexus with crimes of humanity, genocide, and war crimes within the corpus of international norms and criminal prohibitions as well as the historical development of wartime sexual acts as prosecutable war crimes.

Human skin physiology changes during the course of life involving age-related changes in skin appearance. It has been suggested that eggshell membrane, a natural ingredient containing collagen, hyaluronic acid, elastine, among others, can be used for improving skin. However, there are limited clinical studies using eggshell membrane as a dietary supplement to study skin health. The efficacy of Ovoderm®, an oral supplement from eggshell membrane, on skin biophysical parameters related to cutaneous aging was evaluated.
On the thinning variations in hydrostatic forming of sheet metal
Authors: Nguyen Thu Thi , Trung N.D.
Published: March 2021

In sheet metal forming, thinning phenomenon is one of the most concerned topics to ameliorate the final quality of the manufactured parts. The thinning variations depend on many input parameters, such as technological parameters, geometric shape of die, workpiece’s materials, and forming methods. Hydrostatic forming technology is particularly suitable for forming thin-shell products with complex shapes. However, due to the forming characteristics, the thinning variations in this technology are much more intense than in other forming methods. Therefore, in this paper, an empirical study is developed to determine the thinning variations in hydrostatic forming for cylindrical cup. Measurement of thickness at various locations of deformed products are conducted to investigate the thickness distribution and determine the dependence of the largest thinning ratio on the input parameters (including the blank holder pressure, the relative depth of the die and the relative thickness of the workpiece). The results are expressed in charts and equation which allow determining the effect of each input parameter on the largest thinning ratio.
Einflüsse der Linguistik auf den Fremdsprachenunterricht an polnischen Mittelschulen in den 60er und 70er jahren
Authors:   Uniwersytet w Białymstoku, Harbig Anna Maria
Published: March 2021

The article presents linguistic theories of the 1960s and 1970s in the USA and Western Europe in the context of foreign language teaching and investigates their reception in Polish glottodidactics. The selected research subject are secondary school curricula for teaching English, French and German. A conclusion drawn on the basis of the analysis of the 1964 and 1966 curricula is that teaching West European languages was influenced by structuralism, British contextualism in particular. The curricula were characterized by a structural-situational approach expressed by the predominance of a spoken language, linguistic models’ situationalism and authenticity (dialogues in everyday life situations), a privileged position of syntax and the use of pattern drill. The analysis of the 1977 curriculum reveals a continuation of previous theoretical assumptions to a great extent. On the other hand, the impact of pragmalinguistics helped to include such issues as learner’s needs, focusing linguistic material on expressing intentions, or paying attention to language register and utterance adequacy, particularly in the context of linguistic errors’ evaluation. Even though the curriculum itself was not implemented into practice due to abandonment of the educational system reform, it formed the basis for works on curriculum in the 1980s. To sum up, it may be claimed that in spite of mostly unfavourable political conditions of the 1960s and 1970s, Polish glottodidactics aimed to maintain a contact with Western linguistics and attempted to transfer linguistic theories formed on its basis into foreign language teaching in Polish schools.

Pituitary metastasis unveiling a lung adenocarcinoma
Authors: Lopes Ana M , Pereira Josué , Ribeiro Isabel , Martins da Silva Ana , Queiroga Henrique , Amaral Cláudia
Published: March 2021

Pituitary metastasis (PM) can be the initial presentation of an otherwise unknown malignancy. As PM has no clinical or radiological pathognomonic features, diagnosis is challenging. The authors describe the case of a symptomatic PM that revealed a primary lung adenocarcinoma. A 62-year-old woman with multiple sclerosis and no history of malignancy, incidentally presented with a diffusely enlarged and homogeneously enhancing pituitary gland associated with stalk enlargement. Clinical and biochemical evaluation revealed anterior hypopituitarism and diabetes insipidus. Hypophysitis was considered the most likely diagnosis. However, rapid visual deterioration and pituitary growth raised the suspicion of metastatic involvement. A search for systemic malignancy was performed, and CT revealed a lung mass, which proved to be a lung adenocarcinoma. Accordingly, the patient was started on immunotherapy. Resection of the pituitary lesion was performed, and histopathology analysis revealed metastatic lung adenocarcinoma. Following surgery, the patient underwent radiotherapy. More than 2 years after PM detection, the patient shows a clinically relevant response to antineoplastic therapy and no evidence of PM recurrence.

Learning points:

Although rare, metastatic involvement of the pituitary gland has been reported with increasing frequency during the last decades.

Pituitary metastasis can be the initial presentation of an otherwise unknown malignancy and should be considered in the differential diagnosis of pituitary lesions, irrespective of a history of malignancy.

The sudden onset and rapid progression of visual or endocrine dysfunction from a pituitary lesion should strongly raise the suspicion of metastatic disease.

MRI features of pituitary metastasis can overlap with those of other pituitary lesions, including hypophysitis; however, rapid pituitary growth is highly suggestive of metastatic disease.

Survival after pituitary metastasis detection has improved over time, encouraging individualized interventions directed to metastasis to improve quality of life and increase survival.
La importancia de la ética, el respeto a la autodeterminación y los derechos fundamentales de los pueblos indígenas en aislamiento en la antropología
Authors: Huertas Castillo Beatriz
Published: March 2021

Este artículo aborda el resurgimiento de planteamientos, desde la antropología, a favor de que los Estados tomen la iniciativa de establecer relaciones directas y permanentes con pueblos indígenas, o parte de ellos, que viven en aislamiento. Analiza el contexto y los argumentos utilizados por los impulsores de esta posición en la actualidad, así como los impactos que iniciativas similares han tenido en pueblos indígenas. En contraposición, expone el proceso histórico, los principios y los avances del enfoque de respeto a la autodeterminación y los territorios de estos pueblos. En esa línea, apuesta por una antropología respetuosa de las decisiones de los pueblos en aislamiento sobre su forma de vida y el nivel de interacción que desean tener con el entorno. A la vez, plantea la necesidad de contribuir a garantizar la seguridad jurídica y la protección de sus territorios, implementar medidas preventivas en salud y anteponer el respeto de sus derechos fundamentales a intereses personales, gubernamentales, económicos u otros al momento de tomar decisiones que los afecten.
Reflective or Diffractive Learning/Teaching? Concurrences of Paul Ramsden And Karen Barad’s Approaches
Authors: Rybačiauskaitė Karolina
Published: March 2021

In this article it is argued that the optical metaphor and critical practice of diffraction further developed by Donna Haraway and Karen Barad might be no less significant than the widely spread notion of reflection, when the questions of various practices of knowledge are addressed. By considering Paul Ramsden’s approach to learning/teaching and its underlying theory in higher education alongside Karen Barad’s methodology of diffraction, it is shown that Ramsden’s understanding of learning/teaching is rather based on the theoretical assumptions of diffractive practice. His notion that teaching/learning are closely related and actively shaping each other, and that learners are not disconnected from the environment and their previous experiences with the subject matter and learning process itself, adds to Barad’s onto-epistemological position that knowers know the world at the same time as being the part of the world in its ongoing intra-activity. Ramsden’s understanding of relation is diffractive, because it is not about predefined binary entities and their fixed identities, but about layers and entanglements of various previous experiences and reactions to the learning environment. In addition, looking at learning/teaching processes through a different perspective also leads to a different approach to teaching and other ways of problem-solving. Both Ramsden and Barad distrust homologies, analogies, and causality-based conceptions of knowledge sharing. Instead, the ability to respond to an always new learning/teaching environment is assessed, which implies a diffractive type of sensitivity to the context, iterative process of re-turning, and the creation of dangerously indeterminate relationships and commitments. In this way, some of Barad’s philosophical notions, i.e., the diffraction pattern, intra-activity, re-turning, and others, also may acquire new practical content.
UsabilityZero: Can a Bad User Experience Teach Well?
Authors: LIMA Adriano Luiz de Souza , BENITTI Fabiane Barreto Vavassori
Published: March 2021

Interfaces with good usability help their users complete more tasks in less time and with less effort, which gives them greater satisfaction. Given the vast array of options available to users today, usability is an important interface feature that may lead to the commercial success or failure of a software system. Despite its importance, few educational tools are available to help usability teachers and students. Knowing how to measure interface usability is one of the basic concepts that students should learn when they study the theme. This paper presents UsabilityZero, a web application to support the teaching of usability concepts to undergraduate students. By using UsabilityZero, students interact with a system displaying a reduced usability interface and, later, with the same system exhibiting an increased usability interface. Considering the use of UsabilityZero by 64 students, the differences between the interface with reduced and increased usability were: (i) 61.5% decrease in the number of clicks; (ii) 62.2% decrease in the time to perform tasks; (iii) 92.9% effectiveness increase; and (iv) a 277.3% satisfaction increase. During their experience with UsabilityZero, students learn how to measure efficiency, effectiveness, and satisfaction of user interfaces. After using the application, Information Systems and Computer Science students who had never been in touch with the subject could identify key usability aspects. The students’ perception of efficiency, effectiveness, and satisfaction as usability measures was higher than 80%. Also, they could identify some usability criteria and understand how measurements change when some of them are present in the interface design. As a result, over 92% of these students said they recognized the importance of usability to the quality of a software product, and 79% declared that their experience with the application would contribute to their professional lives.

Mecamylamine is a nonselective antagonist of nicotinic acetylcholine receptors that was developed as an antihypertensive medication and is now being studied for its beneficial effects in several pathological conditions, such as substance abuse, depression, anxiety and epilepsy. In this work, we investigate the effect of mecamylamine on the manifestations of seizure-like activity evoked by perfusion of hippocampal slices with low-Mg2+ solution of artificial cerebrospinal fluid. Reducing Mg2+ concentration in extracellular solution induced two distinct types of epileptiform activity: recurring seizure-like activity and continuous discharges. Application of mecamylamine significantly increased internal frequency of recurring seizurelike activity and significantly decreased inter-event intervals between continuous discharges. We also show that mecamylamine significantly decreased internal frequency of continuous epileptiform discharges. The results of our work show that mecamylamine exerts modulatory effect on the low-Mg2+ epileptiform activity induced in hippocampal acute rat brain slices. Additionally, obtained results indicate the role of nicotinic acetylcholine receptors in the modulation of hippocampal network activity, which might explain some of the therapeutic effects of mecamylamine in CNS.

The effects of transnasal introduction of microRNA (miR-101) in liposomal form on the structural and functional organization of sleep were investigated under conditions of modeling Alzheimer's disease in rats of late adulthood. It is shown that in experimental amyloidosis, course administration of miR101 promotes a significant (22-fold) increase in the duration of the deep slow-wave phase and a two-fold increase in the production of paradoxical sleep that is accompanied by a normalization of the rhythmic organization of the wake-sleep cycle and reflects the positive direction of these effects on its qualitative characteristics, probably, due to the inhibitory effect on the synthesis of the precursor of β-amyloid peptides. The results obtained may indicate the prospects for further study of the therapeutic potential of miR-101.

Subject and Purpose. The paper addresses interaction processes going in the ocean–atmosphere system and is concerned with their research by the method of radar remote sensing. Specifically, the matter of concern is the detection and parameter estimation of long waves, including nonlinear ones, on the ocean surface. Methods and Methodology. In August 1988, a series of successive radar surveys of long surface wave manifestations on the Pacific Ocean surface was carried out in the 3 cm wave range by means of an airborne X-band radar system “Analog”. The analysis of the results includes estimation of both spatial and frequency features of the detected long-wave packets and, also, a comparison of the measurement results with model calculations performed in the framework of theory of radio wave scattering by the sea surface in the presence of seismic wave effects. Results. Radar images of wave packets of long surface waves in the open ocean have been obtained. From the imaging data, the spatial scale (5…10 km) of these waves, the lengths (1…5 km) of wave packet components and the wave packet velocity (6.1 m/s) have been derived. Analysis has been given to the nonlinear form of wave packet components, and their amplitudes have been estimated by comparing the experimental and theoretically obtained radio contrasts. The bathymetry of the surface-wave track has been performed to suggest that the observed wave packet represents a set of solitons generated by a seismic impact with the further underwater collapse. Conclusions. A possibility has been demonstrated for monitoring wave packets of long surface waves in their propagation dynamics. The experiments of the sort for gaining a deeper insight into the ocean–atmosphere interaction physics can be conducted by means of not only airborne but also spaceborne radar systems with allowance made for the rate of surveys in both time and space.

Subject and Purpose. The paper is devoted to the microwave propagation over the sea in the nearshore region. Emphasis is on microwave attenuation measurements in the semi-shade and deep-shade areas with a view to study conditions of the microwave propagation on a beyond-the-horizon path in the nearshore area using a radar method. Methods and Methodology. A radar technique, developed and tested, provides measuring a microwave attenuation coefficient along a 60 km long beyond-the-horizon path in the tropospheric surface layer. High-grade radar and Doppler radar beacons (racons) are employed. Of interest are experimentally obtained temporal dependences of signals from racons situated at different heights and, also, spatial field distribution curves from a steadily moving racon running a height 1 to 27 m for 25 minutes. Results. A prototype of high-grade X-band coherent continuous-wave (Doppler) radar has been designed and fabricated. A radar technique has been developed and tested for the analysis of microwave beyond-the-horizon propagation conditions in the shadow region, which involves continuous-wave (Doppler) radar and Doppler racons with a radar cross section (RCS) of about 60 m2. Conclusions. The technique proposed enables reliable tracking of racon responses up to a double radiohorizon range on over-sea paths. This technique can be used for radar calibrations when dealing with various location problems in the nearshore area, including detection and tracking small-size and low-flying targets and their radar identification.

Subject and Purpose. The development and prototype making of a laser rangefinder operating in the 1.50…1.70 μm spectral region is reported. This wavelength region is attractive to both laser producers and laser users for, first of all, relative eye-safety of radiation. Methods and Methodology. The paraxial scheme of rangefinder construction is used, involving a software-controlled power supply of laser radiation with technical arrangements providing its adaptation to varying operating conditions. The alignment of the transceiver channels is provided with laser beam visualization methods. Results. A pulsed laser rangefinder operating at a 1.54 μm wavelength has been developed, a prototype has been made. The rangefinder essentially consists of the transmitting and receiving channels and the visual channel for targeting. The radiation source is a pulsed laser on ytterbium-erbium glass with semiconductor diode pumping and modulated Q-factor. The laser provides a 6 mJ power pulse of 25 ns duration and 5 mrad radiation divergence. A laser light spot of a required aperture is formed using a Galilean telescope system. For the photodetector of the reflected radiation, a pin-photodiode with a photosensitive area diagonal of 0.3 mm and a 2.5 ns time resolution is used. The echo signal processing module has been developed and performed, providing a high-precision registration of a time delay between the starting and reflected pulses. An effective method with the use of a charge-coupled device and an LCD monitor has been proposed and implemented for the alignment of all the three rangefinder channels.
