Consumers' Perception towards Organic Products before and after the COVID-19 Pandemic: A Case Study in Bihor County, Romania.

Organic products have grown ever more popular in recent years due to increased concerns regarding one's health, the environment, and sustainability. The COVID-19 pandemic has only accelerated this growth, prompting producers to adapt to a rapidly growing market while maintaining the same standard of quality. We have conducted a questionnaire-based pilot study on 190 organic food consumers from Bihor county, Romania, in order to analyze the main factors influencing customers' beliefs regarding organic food consumption, as well as assess the extent to which their consumption frequency changed after the pandemic.

Determinants of Choice and Wine Consumption Behaviour: A Comparative Analysis between Two Counties of Romania.

Wine, one of the world's oldest and most popular beverages, has a distinct variety matching a diverse base of consumers worldwide. The study was conducted in two counties of Romania in order to identify consumers' perception towards wine consumption, as well as the driving factors behind wine consumption and the decision process of choosing a certain type of wine. Thus, four factors were identified through principal component analysis: intrinsic cues and consumers' experience, extrinsic cues and origin, notoriety and the label and package of the wine, correlating them with the socio-demographic characteristics of our respondents.

The impact of EAES Fellowship Programme: a five-year review and evaluation.

Background: The European Association of Endoscopic Surgery (EAES) fellowship programme was established in 2014, allowing nine surgeons annually to obtain experience and skills in minimally invasive surgery (MIS) from specialist centres across the Europe and United States. It aligns with the strategic focus of EAES Education and Training Committee on enabling Learning Mobility opportunities.

Prostheses Used in Laparoscopic Inguinal Hernia Repair: Biocompatibility, Postoperative Complications and Quality of Life - Review of the Literature.

Introduction: There is a continuous concern about meshes used in laparoscopic inguinal hernia repair, which mainly relates to their biocompatibility and ability to decrease postoperative complications and recurrence rate; in other words, efforts are made to find the "ideal" prosthesis.

Objectives: To evaluate different prostheses used in laparoscopic inguinal hernia repair in terms of biocompatibility, postoperative complications, recurrence rate and quality of life, so that all the features could lead us to the "ideal" mesh.

Material And Method: Randomized controlled trials, reviews, prospective and retrospective studies, retrospective cross-sectional and experimental studies on animals published between 2000 and 2016 were analysed with respect to several features of a mesh: biocompatibility, postoperative complications, recurrence rate and quality of life.

Are There Specific Indications for Laparoscopic Appendectomy? A Review and Critical Appraisal of the Literature.

Introduction: Laparoscopic appendectomy (LA) has proven to be a feasible alternative to open appendectomy (OA). However, as some of the purported advantages of LA (versus OA) are marginal, evidence is accumulating that appendectomy may not be necessary for uncomplicated appendicitis and there is concern about using laparoscopy for all patients with suspected acute appendicitis. In spite of widespread popularity and use, the literature reporting the indications is sparse and sometimes misleading (i.

Laparoscopy in penetrating abdominal trauma.

If morbidity and mortality are to be reduced in patients with penetrating abdominal trauma, first priority goes to prompt and accurate determination of peritoneal penetration and identification of the need for surgery. In this setting, laparoscopy may have an important impact on the rate of negative or non-therapeutic laparotomies. We analyzed indications and patient selection criteria for laparoscopy in penetrating trauma along with outcomes.

Stevens's brightness law, contrast gain control, and edge integration in achromatic color perception: a unified model.

The brightness of an isolated test patch is related to its luminance by a power law having an exponent of about 1/3, a result known as Stevens's brightness law. The brightness law exponent characterizes the rate at which brightness grows with luminance and can thus be thought of as an "exponential" gain factor. We studied changes in this gain factor for incremental and decremental test squares as a function of the size of a surrounding frame of homogeneous luminance.
