PEDOPHILIA (DITINJAU DARI ASPEK PELAKU, KRIMINALITAS DAN PERLINDUNGAN ANAK)
Authors: Prasetyo Ratna Azis 
Published: October 2019

Abstract. This article aims to explain the concept of pedophilia in terms of the perpetrators, criminality and child protection aspects. During this time children who are victims of pedophiliac suffer prolonged psychological injuries and even lead to death. Meanwhile, the legal settlement is not yet comparable to the injuries suffered by the victims and light punishment tends to make the sexual violence repeated. One of the light sentences for pedophiliacs is that the criminal law in this country has not specifically regulated criminal offenses and on the other hand, the concept of pedophilia is still considered as a mental disorder. Therefore, in handling it is not enough to rely on a legal approach, more than that the handling orientation needs to be directed at child protection. This is done by taking preventive measures such as fostering social sensitivity of the community, optimizing the role of social agents such as local social and institutional organizations and instilling early sex education in children. Abstrak. Artikel ini bertujuan untuk menjelaskan konsep pedophilia ditinjau dari aspek pelaku, kriminalitas dan perlindungan anak. Selama ini anak-anak yang menjadi korban para pedophiliac mengalami luka psikologis berkepanjangan dan bahkan berujung kematian. Sementara itu, penyelesaian secara hukum dirasa belum sebanding dengan luka yang dialami korban dan hukuman yang ringan cenderung membuat tindakan kekerasan seksual tersebut terulang. Hukuman yang ringan bagi para pedophiliac ini salah satunya karena hukum pidana di negara ini belum mengatur secara khusus dalam delik pidana dan disisi lain, konsep pedophilia ini masih dianggap sebagai salah satu gangguan mental. Oleh sebab itu, dalam penanganannya tidak cukup dengan mengandalkan pendekatan hukum, lebih dari itu orientasi penanganan perlu diarahkan pada perlindungan anak. Caranya dengan melakukan upaya-upaya preventif seperti menumbuhkan kepekaan sosial masyarakat, mengoptimalkan peran agen-agen sosial seperti organisasi kemasyarakatan dan kelembagaan lokal dan menanamkan pendidikan seks usia dini pada anak-anak.

Ten Years of Strategic Collaboration of Libraries in Digital Preservation
Authors: Zarnitz Monika , Bähr Thomas , Arning Ursula 
Published: October 2019

The German National Specialist Libraries cooperate closely in the field of digital preservation. One of the partners hosts the preservation system, while each library creates its own workflows and is free to ingest its digital material into this system. This paper delineates the factors for success of this collaboration. It describes the different aspects of collaboration in digital preservation and describes the benefits and costs of cooperation in this field as a case study.
Digital preservation is resource intensive and the required technology is complex. Therefore the libraries benefit from synergy effects: Reduced cost by sharing the preservation system, usage of similar workflows and formats of digital objects, work sharing in networking activities and staff training. The paper also stresses the advantages and difficulties while applying for certificates in a consortium. Their collaboration extends to intensive national and international networking activities, which yield more contacts than a single library could maintain if it acted on its own. The libraries’ staffs are active in working groups of nestor – the German network for digital preservation – and in working groups of the Open Preservation Foundation.
Evaluation of positive serological screening test rates in blood donors with ABO and Rh type blood groups
Authors: Eren Canan 
Published: October 2019

Background: Blood transfusion is a life-saving method in emergencies. However, it also carries the risk of pathogen transmission, which is called transfusion transmitted infections (TTIs). All donated blood samples were screened for hepatitis B surface antigen (HBsAg), anti-hepatitis C virus antibody (anti-HCV), anti-human immunodeficiency virus antigens (anti-HIV½) and syphilis using Venereal Disease Research Laboratory (VDRL) test.
This study was designed and carried out to determine the seroprevalences of TTIs among blood donors with different ABO and Rh blood groups. Identification of a relation between different blood groups and TTIs was anticipated.
Methods: All blood donors data obtained from the Blood Center of Marmara University Pendik Training and Research Hospital between January 2013 and October 2018 are analyzed retrospectively. Serum samples were examined for HBsAg, anti-HCV, anti-HIV½, and VDRL.
Results: HBsAg and anti-HIV½ positivity positivity rates were not statistically different according to ABO blood groups (p>0.05). Anti-HCV positivity rates are partially statistically significant (p<0.05). While the incidence of anti-HCV in patients with AB Rh (+) cases was significantly higher than that of 0 Rh (+), A Rh (+) and AB Rh (+) groups, no significant difference was found for the other analyzed blood groups (p>0.05). VDRL positivity rates did not differ significantly (p>0.05). Seropositive cases, as reported by Rh type blood group; HBsAg, anti-HCV, anti-HIV½, and VDRL positivity rates were not statistically significant (p>0.05).
Conclusions: No significant relationship was found among TTIs and ABO and Rh type blood groups. For blood transfusion safety, screening tests should always and carefully be performed.

Dengue virus distributed in tropical and subtropical regions in the world. DENV viruses are transmitted between humans primarily by Aedes aegypti and Aedes albopictus mosquitoes and are endemic in most areas in which the vectors occur. Four serotypes of dengue virus are DENV-1, DENV-2, DENV-3 and DENV-4. DENV-2 is comprised of six genotypes. Ethanol precipitation is a commonly used technique for concentrating and de-salting nucleic acids (DNA or RNA) preparations in aqueous solution. RNA isolation by combining Guanidinium thiocyanate and phenol reported has been reported. In this report, we investigated RNA isolation from DENV-2 using QIAamp Mini Kit with 2-Isopropanol, Methanol, Chloroform precipitation solvent. Electrophoregram showed DNA band as the result of RNA isolation with methanol and 2-isopropanol are produced quite well. Dna band of the of RNA isolation with chloroform solvent has the lowest intensity than methanol and 2-isopropanol. This study showed that methanol and 2-isopropanol can used as precipitation solvent for isolating RNA.
