A Secure and Verifiable Computation for k-Nearest Neighbor Queries in Cloud

The popularity of cloud computing has increased significantly in the last few years due to scalability, cost efficiency, resiliency, and quality of service. Organizations are more interested in outsourcing the database and DBMS functionalities to the cloud owing to the tremendous growth of big data and on-demand access requirements. As the data is outsourced to untrusted parties, security has become a key consideration to achieve the confidentiality and integrity of data. Therefore, data owners must transform and encrypt the data before outsourcing. In this paper, we focus on a Secure and Verifiable Computation for k-Nearest Neighbor (SVC-kNN) problem. The existing verifiable computation approaches for the kNN problem delegate the verification task solely to a single semi-trusted party. We show that these approaches are unreliable in terms of security, as the verification server could be either dishonest or compromised. To address these issues, we propose a novel solution to the SVC-kNN problem that utilizes the random-splitting approach in conjunction with the homomorphic properties under a two-cloud model. Specifically, the clouds generate and send verification proofs to end-users, allowing them to verify the computation results efficiently. Our solution is highly efficient from the data owner and query issuers’ perspective as it significantly reduces the encryption cost and pre-processing time. Furthermore, we demonstrated the correctness of our solution using Proof by Induction methodology to prove the Euclidean Distance Verification

Kamus Bahasa Indonesia-Kulawi

This review supplies the reader with a detailed overview on the utilization of intramolecular processes for a design and synthesis of prodrugs. It is well known that a respected number of drugs suffer from low bioavailability, toxicity, unpleasant taste and presystemic first-pass metabolism which result in drug inactivation. The classical prodrug approach in which the linkage attaching the parent drug to its non-toxic linker and cleaved by in vivo enzyme’s catalyzed reactions has proven its success in solving toxicity and bioavailability related issues. On the other hand, prodrugs based on chemical interconversion in which the prodrug releases the corresponding active parent drug via inter or intramolecular chemical process in the absence of an enzyme is considered as a better alternative approach since the prodrug cleavage is not dependent in the efficiency or quantity of the enzyme catalyzes the interconversion of the prodrug. Examples of successful prodrugs using the chemical approach via intramolecular processes such as cyclization reactions are illustrated as well. In addition, another part of this review is devoted to cover reported studies on enzyme models and their utilization for the design and synthesis of a variety of novel prodrugs. In this approach, computational calculations using DFT and MM methods were exploited and correlations between experimentally determined and computed values of the rate-limiting step in the studied intramolecular processes were utilized in the prodrugs design. Selected examples of the designed prodrugs include aza-nucleosides for the treatment of myelodysplastic syndromes, the anti-Parkinson’s agent dopamine, the anti-viral acyclovir, the anti-malarial atovaquone, and statins for lowering cholesterol levels in the blood, the antihypertensive atenolol, the antibacterial cefuroxime, the anti-bleeding tranexamic acid, the decongestant phenylephrine, and the pain killer paracetamol

Perkembangan Zaakwaarneming Di Indonesia Analisis Putusan No 350/Pdt.G/2014/Pn.Jkt.Pst.

Perwakilan sukarela adalah suatu perbuatan yang dikerjakan oleh seseorang, dengan pernyataan atau alasan yang mendasar dan patut, yang memiliki tujuan guna mengurus kepentingan yang menanggung tanggung jawab orang lain dengan tidak adanya wewenang untuk itu, baik itu berasal dari perbuatan hukum ataupun peradilan, dimana dengan sukarela bermaksud untuk mengurus kepentingan orang lain ataupun tanpa pengetahuan orang yang kepentingannya diatur. Penelitan ini penulis memiliki tujuan guna memahami, mengetahui, serta menganalisis permasalahan tentang perwakilan sukarela dan perkembangannya di Indonesia. Metode hukum normatif adalah cara peneltian dengan mencari dasar dari bahan pustaka yang didalamnya berasal dari data sekunder. Pada artikel ini pembahasan mengenai permasalahan tanah, baik itu kepemilikan tanah atau tinggal di tanah seseorang. Seperti pada kasus gestor yang melakukan suatu zaakwarneming guna menetap di tanah tersebut, tapi terkadang gestor pun melaksanakan suatu tindakan secara sepihak dan dari dominus tidak adanya suatu persetujuan. Hal tersebutlah dianggap perbuatan itu tidak menguntungkan bagi dominus itu sendiri. Contoh pada kasus Putusan Pengadilan No 350/Pdt.G/2014/PN.Jkt.Pst. kemudian bandingnya naik menjad No 02/Pdt/2016/Pt.DKI. Yang mana permasalahan itu menjelaskan orang yang melakukan pengurusan memakai tanah lahan orang yang kepentingannya diurus  tanpa izin terlebih dahulu. Oleh sebab itu, karena ada permasalahan yang timbul antara dominus dan gestor, maka orang yang melakukan pengurusan tersebut  memerlukan suatu hukum yang dapat melindungi dengan pasti dan sudah diatur di dalam suatu peraturan. Namun pada kenyataannya, aturan terkait itu pada saat ini masih abu-abu atau belum ada suatu kepastian yang merujuk kepada hal tersebut dan hanya merujuk kepada putusan hakim.  Kata Kunci: Perlindungan Hukum, Zaakwarneming, Gestor, Dominus, Putusan Haki

Vocational Interests of Middle and High School Students in the UAE

This paper investigated the vocational interests of students in the UAE and determined its relationship to gender and grade level. The Emirates Scale for Vocational Interests- Revised (ESVI-R) was used to attain the goal of the investigation. The ESVE-R was administered to 1920 students in the different emirates who were in the 9th, 10th, 11th, and 12th grades. Accordingly, the sample was comprised of 866 (45.1%) male and 1054 (54.9%) female students. The data were analyzed using the appropriate descriptive and inferential statistical protocols. The results showed that there are significant gender differences in most of the subscales of ESVI-R whereas there are significant differences in some of the subscales according to students' grade level. The study concluded that the vocational interests of the students demonstrated stability along grade levels and that there was a notable shift in the vocational interests of female students in the trajectory of seeking an equal opportunity with their male counterparts.
