Reconstruction of sufficient buccal peri-implant keratinised mucosa width (PIKM-W) is reported to reduce the symptoms of peri-implantitis. In order to reduce the drawbacks of autogenous graft harvesting, we investigated a novel porcine dermal matrix (XDM, mucoderm®) using a modified surgical technique for augmentation of PIKM-W. Twenty-four patients were recruited with insufficient (<2 mm) PIKM-W. After split thickness flap preparation, the XDM was trimmed, rehydrated and tightly attached to the recipient periosteal bed using modified internal/external horizontal periosteal mattress sutures via secondary wound healing. Change of the PIKM-W and dimension of the graft remodelling were evaluated at 6 and 12 months postoperatively. The mean PIKM-W changed from 0.42 ± 0.47 to 3.17 ± 1.21 mm at 6 M and to 2.36 ± 1.34 mm at 12 M in the maxilla and from 0.29 ± 0.45 mm to 1.58 ± 1.44 mm at 6 M and to 1.08 ± 1.07 mm at 12 M in the mandible. Graft dimensions decreased by 67.7 ± 11.8% and 81.6 ± 16.6% at 6 M, and continued to 75.9 ± 13.9% and 87.4 ± 12.3% at 12 M, in the maxilla and mandible, respectively. Clinical parameters showed statistically significant intra- and intergroup differences between the baseline and 6 and 12 months (p < 0.05). The present technique using the XDM was safe and successfully reconstructed PIKM-W in both arches. The XDM alone seems to be a suitable alternative to autograft for PIKM-W augmentation in the maxilla. [ABSTRACT FROM AUTHOR]

After World War II, the Soviet model was introduced in the countries of the Eastern Bloc, including Hungary, not only in the political, economic, and social spheres, but also in the field of science, and within it, in the system of qualification. The system introduced - which remained in place until 1993 - was aimed at creating a new intellectual class, so candidates had to meet political as well as professional requirements. In a pilot study on the process of knowledge construction in the next generation of scientists, we analyzed reviewers' opinions on doctoral dissertations in the 1970s. The theoretical framework was provided by Stichweh and Becker's notion of discipline and Bourdieu's field theory on the functioning of scientific disciplines. Qualitative content analysis was used to process 20 reviews. Although the candidates had to meet both professional and political criteria, the referees put more emphasis on professionalism. The analyzed reviewers' opinions of the show, that those within the scientific field already had more flexibility than those wishing to enter it, but that this meant only relative research freedom.

Magyarország geopolitikai helyzetében a 20. században többször történt jelentős változás. Ezek a fordulópontok meghatározták a magyar katonai stratégia tartalmát is. A tanulmány azt vizsgálja, hogy a geopolitikai helyzet átalakulása hogyan hatott a katonai stratégia térszemléletére a trianoni békeszerződéstől napjainkig.

Damage caused by game species in agricultural areas has increased in recent decades in Hungary. This trend is causing significant conflicts between wildlife managers and farmers. In maize fields, rooting damage by wild boar after sowing is a major concern. We aimed to study which factors can influence the occurrences of the damage The study was carried out in Győr-Moson-Sopron county, north-western Hungary, on a 6000 ha hunting area for two years. The forest cover is approximately 20%, and the wild boar harvesting averaged 118 individuals in the two years of the study. We visited the maize fields periodically after sowing. We measured the maximum distance of the rooting damage from the field edges to the inner parts of the field in every 20 m, and we measured the length of the damaged edges as well. We also surveyed the crop in adjacent fields. We recorded the number of hunting occasions and hours spent hunting. These were used to determine the spatial and temporal patterns of rooting damage, as well as the effects of hunting pressure and the impact of adjacent areas. It was found that the distance of rooting damage from the field edge was 23 meter on average and the maximum observed was 150 meter. It can be observed that 90% of the rooting damage remained within 50 m of the edge. The survey of the edges showed that of the total 8272 meters of available edges, 3205 metres were damaged, representing 38.7%. The most preferred edge for damage was rape, followed by forest. During the study, the hunting pressure applied to control game damage kept damage low (first year: 5.5 hours/night, second year: 3.7 hours/night). In the first year, the average area which affected by damage was 1.3 ha, represents an area ratio of 3.5% of the total area. In contrast, in the second year, the average was 0.03 ha, representing 0.18% of the total area. The negligible damage in the second year was due to the start of hunting immediately after sowing. In contrast, in the first year, hunting started after the first damage had occurred. [ABSTRACT FROM AUTHOR]
