Peter Pan-szindróma - egy anorexiás férfi családterápiája. Esetismertetés = Peter Pan syndrome: Family therapy of an anorectic male patient. A case study

A korábban jellegzetesen női betegségként emlegetett anorexia nervosa egyre gyakrabban fordul elő férfiak között is. A tanulmány áttekinti a Peter Pan-szindrómának is nevezett férfi anorexia jellemzőit. Közöttük az egyik fontos sajátosság a posztadoleszcencia jelensége. Magyarországon eddig két közlemény jelent meg, amely anorexiás férfiak pszichoterápiás folyamatát ismertette. A jelen tanulmány egy mozaikcsaládban élő, 19 éves anorexiás férfibeteg tíz ülésből álló családterápiás folyamatát ismerteti. Három hónapos utánkövetés tünetmentességet igazolt. A terápiás eredmény elérésében a családi hierarchiaviszonyok újrarendeződése fontos szerepet játszott. A sikeres terápia arra hívja fel a figyelmet, hogy az anorexiában a családterápia fontos szerepet játszik, ezt nemzetközi adatok is megerősítik. Ma egyre fontosabbá válik a posztadoleszcencia szerepe a családi diszfunkciók között. Ennek kezelése, a szeparáció-individuáció folyamatának erősítése a terápia lényeges célkitűzései közé tartozik. | Anorexia nervosa has been mentioned as a female syndrome so far. However, the number of male disorders is increasing. This study reviews the characteristics of the male anorexia, which is discussed as Peter Pan syndrome as well. Among its characteristics the phenomenon of postadolescence is one of the most important. So far in Hungary two studies have been published demonstrating the psychotherapy of male anorectic patients. The present study describes the 10-session long family therapy of a 19-year-old male patient who lives in a patchwork family. In reaching the therapeutic goals the reorganization of the hierarchy in the family was highly important. This therapeutic success highlights the importance of family therapy in the treatment of anorexia nervosa, which is corroborated by international data as well. Nowadays the role of postadolescence is getting more and more important among family dysfunctions. To treat this phenomenon, the enhancement of the process of separation-individuation is one of the most important goal of family therapy

Voluminous D2 source for intense cold neutron beam production at the ESS

The development of the flat moderator concept at ESS recently opened up the possibility that a single flat moderator above the target could serve all the scattering instruments, that rely on high brightness. This would allow for the introduction of a fundamentally different moderator below the target for the complementary needs of certain fundamental physics experiments. To facilitate experiments depending on the total number of neutrons in a sizable beam, the option of a voluminous D2 moderator, in a large cross-section extraction guide is discussed and its neutronic performance is assessed.Comment: 3 pages, 2 figure

In-Pile ⁴He Source for UCN Production at the ESS

ESS will be a premier neutron source facility. Unprecedented neutron beam intensities are ensured by spallation reactions of a 5 MW, 2.0 GeV proton beam impinging on a tungsten target equipped with advanced moderators. The work presented here aims at investigating possibilities for installing an ultra cold neutron (UCN) source at the ESS. One consequence of using the recently proposed flat moderators is that they take up less space than the moderators originally foreseen and thus leave more freedom to design a UCN source, close to the spallation hotspot. One of the options studied is to place a large He-4 UCN source in a through-going tube which penetrates the shielding below the target. First calculations of neutron flux available for UCN production are given, along with heat-load estimates. It is estimated that the flux can give rise to a UCN production at a rate of up to 1.5 . 10(8) UCN/s. A production in this range potentially allows for a number of UCN experiments to be carried out at unprecedented precision, including, for example, quantum gravitational spectroscopy with UCNs which rely on high phase-space density

Low dimensional neutron moderators for enhanced source brightness

In a recent numerical optimization study we have found that liquid para-hydrogen coupled cold neutron moderators deliver 3 - 5 times higher cold neutron brightness at a spallation neutron source if they take the form of a flat, quasi 2-dimensional disc, in contrast to the conventional more voluminous shapes used by now. In the present paper we describe a simple theoretical explanation of this unexpected behavior, which is based on the large difference in para-hydrogen between the values of the scattering mean free path for thermal neutrons (in the range of 1 cm) and its much larger equivalent for cold neutrons. This model leads to the conclusions that the optimal shape for high brightness para-hydrogen neutron moderators is the quasi 1-dimensional tube and these low dimensional moderators can also deliver much enhanced cold neutron brightness in fission reactor neutron sources, compared to much more voluminous liquid D2 or H2 moderators currently used. Neutronic simulation calculations confirm both of these theoretical conclusions.Comment: 6 pages, 2 figure
