A csomagolás részét képezi a jelölés – vagy más néven címke, label –, aminek elsődleges funkciója a termék tulajdonságairól való tájékoztatás, amellett, hogy a vállalat és a fogyasztó egyik legfontosabb találkozási pontja. Kiemelt szerepe van a marketing és a vállalati menedzsment eszköztárában, hiszen a fogyasztói döntéshozatal meghatározó forrása. A szerző írásában a jelölések definícióját, fajtáit és csoportosítását tárja az olvasó elé, majd ismerteti jelentőségét, fontosságát és szerepét az élelmiszer-ipari termékek segítségével. Ezután egy 630 fős megkérdezés eredményeképp a sokdimenziós skálázás (MDS) módszerével a jelölések új értelmezését mutatja be: a jelöléseket három dimenzió mentén lehet elhelyezni (előzetes tudás, érdek, megbízhatóság), valamint ezenkívül a jelölések öt homogén csoportot alkotnak (klasszikus, diétás, funkcionális, tudatos, előállítási). A téma jelentőségét az egészség és a környezet iránti növekvő érdeklődés, valamint a változó jogszabályi környezet is alátámasztja. / === / Signs, labels, claims are to inform consumers of product attributes, and are part of the packaging. Labeling is one of the most important marketing and management tool, while purchase decision is made at the point of purchase. The aim of this paper is to present the basic definitions and elements of information content on food packaging. The author developed a new approach to examine labeling using multidimensional scaling as a result of a pilot study. Labels are to distinguish through three dimensions: precognition, interest and reliability. Beyond that labels can be sorted to five homogeneous clusters based on classic, dietary, functional, conscious and production attributes. The relevancy of labeling is supported by growing interest of health and environmental issues and changing law environment.

AbstractThis review deals with the evolution of bio-based packaging and the emergence of various nanotechnologies for primary food packaging. The end-of life issues of packaging is discussed and particularly the environmental problems associated with microplastics in the marine environment, which serve as a vector for the assimilation of persistent organic pollutants in the oceans and are transported into the food chain via marine and wild life. The use of biodegradable polymers has been a primary route to alleviate these environmental problems, but for various reasons the market has not developed at a sufficient pace that would cope with the mentioned environmental issues. Currently, the biodegradable plastics only constitute a small fraction of the fossil-based plastic market. Fossil-based plastics are, however, indispensable for food safety and minimization of food waste, and are not only cheap, but has generally more suitable mechanical and barrier properties compared to biodegradable polymers. More recently, various nanotechnologies such as the use of nanoclays, nanocellulose, layer-by-layer technologies and polyelectrolyte complexes have emerged as viable technologies to make oxygen and water vapor barriers suitable for food packaging. These technological developments are highlighted as well as issues like biodegradation, recycling, legislation issues and safety and toxicity of these nanotechnologies.

Cone Beam Computed Tomography (CBCT) is the preferred imaging method for a comprehensive orthodontic examination. Thanks to the development of this technique, clinicians today can make most accurate measurements without fear of errors associated with projection distortion or localization of landmarks on radiographs. The quality of CBCT images gives to orthodontists the ability to analyze bone structures, teeth (even impacted teeth), and soft tissue in three dimensions. The accuracy of measurements of hard and soft tissues from CBCT images determines the accuracy of diagnosis and treatment planning. A fundamentally new approach has been proposed, which makes it possible to thoroughly study the bone tissue surrounding the tooth at the stages of planning orthodontic treatment. Аnalysis of radiation studies of patients with dentoalveolar anomalies was carried out to select the optimal treatment tactics and to control its effectiveness.

Purpose Although the literature has established the effect of online reviews on customer purchase intentions, the influence of psychological factors on online ratings is overlooked. This paper aims to examine these factors under the perspective of construal level theory (CLT). Design/methodology/approach Using review data from TripAdvisor and Booking.com, the authors study three dimensions of psychological distances (temporal, spatial and social) and their direct and interaction effects on review valence, using regression analysis. The authors examine the effect of these distances on the information content of online reviews using a novel bag-of-words model to assess its concreteness. Findings Temporal distance and spatial distance have positive direct effects on review valence. Social distance, on the other hand, has a negative direct effect. However, its interaction with the other two distances has a positive effect, suggesting that consumers tend to “zoom-out” to less concrete things in their ratings. Practical implications The findings provide implications for the interpretation of review ratings by the service providers and their information content. Originality/value This study extends the CLT and electronic word-of-mouth literature by jointly exploring the effect of all three psychological distances that are applicable in post-purchase evaluations. Methodologically, it provides a novel application of the bag-of-words model in evaluating the concreteness of online reviews.

Computing capacities have grown exponentially in recent years and 3D-Navier-Stokes methods were developed widely. However it is still not feasible to design a multi-stage compressor directly in three dimensions. Instead, compressor design starts with 1D-design. In accordance with this approach, basic parameters such as the number of stages and stage pressure ratios are determined. In the following 2D-design, the geometry of the flow channel and the main parameters of the blade geometries can be determined. Afterwards in the 3D-design, unsteady and 3D-flow-effects are considered and the design optimized accordingly. Therefore, it is virtually impossible to correct conceptual faults in the 3D-design phase. Thus a robust and reliable 2D-Throughflow-solver including a performance prediction for modern airfoil geometries is necessary. So far there is no efficient methodology known which predicts the performance for all kinds of airfoil geometries, as it would be necessary in a 2D-Throughflow optimization process. In [1, 2] a novel methodology was presented, which is able to predict the performance for a large number of airfoil geometries accurately. This method is based on a large airfoil database which is used to train a surrogate model for airfoil performance prediction. The scope of this work is to validate and to document the progress of this new approach. In Schmitz et al. [1] it was validated on rotor 1 of the 4.5 stage transonic test compressor DLR-RIG250 of the Institute of Propulsion Technology. In this work all 4.5 stages were calculated at different speedlines and different vane positions. The results of the S2-solver are compared to experimental data and 3D-CFD calculations, obtained using the DLR in-house solver TRACE.
