    In this paper we examine the development of school libraries in Turkey. We have also included general information about the Turkish Education System and the Ministry of National Education which is responsible for improving and developing the status of school libraries in Turkey. Based on the results of a questionnaire and interviews with students, teachers and administrators, we review the highlights of the school library development in Turkey. In the 75.200 education institutions run by the Ministry, there are 518.450 teachers and 14.275.281 students at all levels (TBMM, 1994: 47). The tremendous pressure of this large student population on the education budget of Turkey will bring into sharp focus of providing school library services in an economic sense

    In this study, the effects of different methods of feeding turkeys on the neuropeptide nesfatin-1 and the hormone irisin were evaluated. A total of 90 turkeys were distributed to three treatment groups, namely T1: conventional system, T2: 50% feed and pasture, and T3: pasture. There were 30 birds in each group with three random replications. The birds were fed for 18 weeks. At the end of the study, blood was collected from 10 birds of each group. Plasma nesfatin-1 and irisin levels were measured with an enzyme-linked immunoassay. The nesfatin-1 levels of male turkeys in T1, T2, and T3 were 0.76 ± 0.1 ng/m, 0.41 ± 0.1 ng/ml, and 1.24 ± 0.2 ng/ml, respectively. Nesfatin-1 levels in the female turkeys in T1, T2 and T3 were 0.53 ± 0.07 ng/ml, 1.18 ± 0.3 ng/ml, 1.32 ± 0.1 ng/ml, respectively. The irisin levels in the male turkeys in T1, T2, and T3 were 575.93 ± 42.5 pg/ml, 188.39 ± 1.8 pg/ml, and 607.54 ± 24.1 pg/ml, respectively. Irisin levels of the female turkeys in T1, T2 and T3 were 603.20 ± 42.2 pg/ml, 241.42 ± 18.4 pg/ml, and 399.29 ± 21.5 pg/ml, respectively. Because nesfatin-1 is involved in regulating food intake, food intake by turkeys might differ, depending on the management system. Different management systems might also alter irisin secreation because it can be induced by exercise

    Interactive media support the creation ofpeople- centered systems that can clarify and simplify the coordination ofhuman action. For interactive media to succeed, they ne- ed to fit gracefully into the lives oftheir users.Therefore, the purpose ofthis research is to determine possible criteria to evaluate the interactive media with special referen­ce to multimedia. Many native and foreigner companies produce multimedia based softuoare. CD market has been developing very fast. Multimedia productions have to be examined with user centered, multi disciplinary frame, and the evaluation model must be set like other information resources have been set. While setting up this eva­luation model basic consideration must have content that meets the user needs.Etkileşimli bilgi kaynaklan insanı temel almakta ve bilgi kullanımını kolaylaştır­maktadırlar. Bu araştırmanın amacı "multimedya” örneğinde etkileşimli bilgi kay­naklarını değerlendirecek unsurları ortaya çıkarmaktır. Birçok yerli ve yabancı şirket multimedya yazılımı üretmektedir. CD piyasası hızla gelişmektedir. Multimedya ürünlerinin kullanıcıyı temel alan değişik disiplinlerin oluşturduğu bilimsel bir çer­çeve içerisinde incelenmesi ve bilgi merkezlerinde kullanılan diğer bilgi kaynakları gi­bi değerlendirme modelinin oluşturulması gerekmektedir. Değerlendirme modelini oluştururken, kullanıcı gereksinimlerinin karşılanmasına çalışılmıştır

    The aim of this study was to determine the effect of three production systems on live weight gain (LWG) of white turkeys by repeated measures analysis of variance (ANOVA) and profile analysis. A total of 81 turkey poults were assigned to intensive (7 male and 19 female), semi-intensive (9 male and 19 female) and extensive groups (11 male and 16 female) at one day old. The poults were wing-banded at day 1 after hatching and weighed individually each week through 16 weeks old. The birds were managed similarly through eight weeks old. After that time, the intensive group was fed concentrated feed indoors. The birds of the semi-intensive group had access to pasture for eight hours a day, and received 50% of the concentrated feed that was consumed by the intensive group. The birds in the extensive group were kept outdoors with shade and grazed on pasture, but did not receive concentrated feed. The bi-weekly LWG of the extensive, intensive and semi-intensive groups were 1191.4 g, 990.6 g and 872.1 g, respectively. Through the 16 weeks of the trial, the effects on LWG of production system, age, and interaction of age and production system were highly significant (P <0.01) in the repeated measures ANOVA. The profile analysis also showed highly significant (P <0.01) production system effects and interaction of production system and age on LWG. Scheffe’s test indicated that the intensive, semi-intensive, and extensive treatments differed (P <0.05)

    Case report: Surgical repair of a large tracheo-esophageal fistula in a patient with post-transplant esophageal lymphoproliferative disorder

    Introduction and importance The management of large malignant tracheo-esophageal fistulas (TEF) is not standardized. Herein, we report a case with a malignant TEF associated with esophageal post-transplant lymphoproliferative disorder (PTLD) for whom we successfully performed a surgical repair. This contributes to the knowledge on how to treat large acquired malignant TEFs. Case presentation A 69-year old male presented with a one-week history of fever, productive cough and bilateral coarse crackles. In addition, he described a weight loss of 10 kg during the past three months. The patient's history included a kidney transplantation twenty years ago. Esophagogastroduodenoscopy with a biopsy of the esophagus was performed nine days before. Histopathology showed a PTLD of diffuse large B-cell lymphoma subtype. Subsequent diagnostics revealed a progressive TEF (approx. 2.0 × 1.5 cm) 3.0 cm above the carina. PET-CT scan showed an esophagus with slight tracer uptake in the middle third (approx. 11.5 cm length, SUV max 7.4). After decision against stenting, transthoracic subtotal esophagectomy with closure of the tracheal mouth of the fistula by a pedicled flap was performed. PTLD was treated with prednisone and rituximab. Tumor progression (brain metastasis) led to death 95 days after surgery. Clinical discussion The treatment of a malignant TEF is complex and personalized while both the consequences of the esophago-tracheal connection and those of the underlying responsible diagnosis have to be considered concurrently. In this case, we considered surgery as the best treatment option due to a relatively good prognosis of the underlying diagnosis (PTLD) and a large fistula. Esophageal or dual stenting, the treatment of choice for small malignant TEF, would have been associated with a high risk of failure due to the wide trachea, extensively dilated esophagus, proximal location and large diameter of the fistula. Conclusion Surgery can be considered for patients with a large acquired malignant TEF and positive long-term prognosis of the underlying diagnosis. Due to the complexity of TEF management, immediate pre-operative multidisciplinary discussion is advised
