BIOFILIA DAN NEKROFILIA: ANAL ISIS SOSIOLOGI SASTRA NOVEL LA BETE HUMAINE KARYA EMILEZOLA
Get PDFBased on the analysis of genetic structuralism suggested by Lucien Goldmann, showed that Emile Zola as an adherent of naturalism, through the mediation of his work LaReteHumaine, has managed to bring a distinctive world view. In his career as an author who engage fully in social and political life of his time, Zola has been firmly demonstrated a world view that is different with the rulers at that time. His involvement in the political field, as well as to the weak, and become victims of an unjust system of
capitalism, and his commitment to the truth which he believed, had produced changes in the field of social and political. This is evident with the recognition of social rights of workers in those days, and the .release of Alfred Dreyfus from prison. Yet all that must be redeemed by his life. Zola died of assassinated by political opponents.
Berdasarkan analisis strukturalisme genetik yang disarankan oleh Lucien Goldmann, menunjukkan bahwa Emile Zola merupakan penganut naturalisme, melalui perantaraan karyanya La Rete Humaine, telah berhasil mengemukakan sebuah pandangan dunia yang khas. Dalam karimya sebagai seorang penulis yang terlibat penuh dalam kehidupan sosial dan politik pada masanya, Zola telah dengan tegas menunjukkan pandangan dunia yang berbeda dengan penguasa pad a waktu itu. Keterlibatannya dalam bidang politik, serta berpihak kepada yang lemah, dan menjadi korban dari suatu sistem kapitalisme yang tidak adil, serta komitmennya kepada kebenaran yang dia percaya, telah menghasilkan perubahan di bidang sosial dan politik. Hal ini terbukti dengan pengakuan hak-hak sosial pekerja dan pelepasan Alfred Dreyfus dari penjara. Namun semua itu harus ia tebus dengan nyawanya. Zola meninggal karena dibunuh oleh lawan-Iawan politiknya
DISKURSUS "ILLEGITIMATE SEXUAL ACTIVITY" ANAK BANGSA DALAM PERSPEKTIF TABLOID INDONESIA
No full textIn Indonesia, sexual activity that has not been legitimized by the state is one of the realities that are constructed by the language of "masculine-heterosexual", as an absolute discourse defines in the hands of the state. This paper is about to dismantle about usage of" masculine-heterosexual" language by the Indonesian mass media discourse in defining and putting illegitimate sexual activity in the landscape of the nation\u27s sexuality discourse in Indonesia. Using critical multiculturalism framework, identity theory and constructivist paradigm, this paper will explore discourse articulated by mass media in the articles that explain those matters. Using discourse analysis as the method, there\u27s four tabloids as research subject, Tabloid Nova No. 1165/XXIII 21-27 Juni 2010, Tabloid Bintang Edisi 997 Tahun XX Minggu Ketiga Juni 2010, Tabloid Wanita Indonesia No. 106921-27 Juni 2010, and Tabloid Genie Edisi 50 Tahun VI, 21-27 Juni 2010.
Di Indonesia, aktivitas seksual yang belum dilegitimasi oleh negara merupakan salah satu realitas yang dikonstruksi oleh bahasa "maskulin-heteroseksual" yang dalam konteks tersebut merupakan diskursus yang pendefinisiannya mutlak di tangan negara. Tulisan ini hendak membongkar lebih lanjut mengenai penggunaan bahasa "maskulin-heteroseksual" oleh media massa Indonesia dalam mendefinisikan serta meletakkan diskursus illegitimate sexual activity anak bangsa dalam lanskap diskursus seksualitas Indonesia. Menggunakan kerangka pikir critical multiculturalism, teori identitas serta paradigma konstruktivis yang berargumen bahwa media massa merupakan agen konstruksi realitas, tulisan ini hendak mengeksplorasi diskursus yang berusaha diartikulasikan media dalam artikel-artikel yang membahas mengenai hal terse but.

Effect of Allicin for Re-epithelialization During Healing in Oral Ulcer Model
Get PDFAllicin (diallyl thiosulfinate) isthe main component offresh garlic with multi-bioactivities astherapeutic agent. Recently,allicin is being proposed as alternative therapy for aphthous ulcer. The purpose of this study was to determine the effect of topical allicin in aqueous garlic extract on re-epithelialization during healing of acetic acid induced oral ulcer model. Thirty malesSDrats aged 2 months were equally divided into two groups as experimental and control groups. After sedated with 0.2 ml intramuscular Ketamine injection, ulcer model was made by applying 99.5% glacial acetic acid-moistened paper disc on rat buccal mucosa.This would generate an immediate necrotic tissue, which produced a single crateriform ulcer in each of the experimental rats for the next two days. In the experimental group, one drop of allicin was applied twice daily onto the lesion. Three rats in each group were sacrificed on days 2, 3, 6, 9 and 12 after induction and were recorded as H₀, H₁, H₄, H₇and H₁₀groups, respectively. The tissue samples from buccal mucosa were processed for Hematoxylin Eosin (HE) staining, and then evaluated histologically. Re-epithelialization was assessed by measuring the thickness of the epithelium using an ocular micrometer under a light microscope. Data were analyzed statistically by Independent t-test with significant p-valueso
