I. INTRODUCTION
The consequences resulting from Human Fall may lead to
serious conditions if proper treatment is not provided. The
majority of serious consequences may be due to delay in
assistance and treatment. Such consequences can be
minimized if their care taker is alerted in time [1].
The possible fall from height during building
construction, painting, mountain climbing, etc.., can be
alerted immediately using the proposed system. The Human
fall detection using ADXL345 MEMS 3-Dimensional
Accelerometer with sensing of fall as output was proposed
[2]. To detect the fall of Elderly Patient by capturing of
images at different angle of inclination through Map-Cam
(Omni-Cam) emerged [3]. Tri-Axial acceleration of human
body is used to detect whether the person is healthy or
unhealthy based on principle of Hidden Markov Model
(HMM) [4]. An address-event vision system detects the
Accidental fall of paralysed, Elderly patient and those who
recently undergone surgery as Home Care Applications [5].
An automated monitoring using Web Camera system which
determine the human fall by detection of face and extraction
features was proposed [6]. The Block Diagram and
Methodology are explained in next chapter followed by
Experimental Results and Conclusion in the Preceding

This chapter by Filip Biały delves into the intricate relationship between artificial intelligence (AI) and democracy, particularly in the context of algorithmic governance. It explores the concept of "predictive democracy," where decision-making is entrusted to AI based on data-driven predictions of citizens' preferences, bypassing traditional democratic processes like elections and parliamentary debates. The author employs a methodological approach combining intuition pumps—thought experiments that illuminate the implications of predictive democracy—and teleological reasoning to analyze the political and conceptual shifts brought about by integrating narrow AI into politics. The analysis highlights the challenges posed by predictive democracy to foundational political concepts such as representation, participation, and decision-making. Biały argues that while AI can enhance decision-making efficiency, it also risks oversimplifying complex moral and political issues and undermining the participatory and deliberative aspects of democracy. The chapter concludes with a critique of proposals for AI-driven governance, emphasizing the need for a nuanced understanding of politics that accommodates technological advancements without compromising democratic values and processes.
Salah satu alasan utama lahirnya beragam teori atau aliran pemikiran hukum adalah upaya untuk mencari jawaban dari pertanyaan apa hakikat dari hukum itu sendiri. berikut ini adalah beberapa aliran hukum yang sering dijadikan sebagai rujukan dalam memahami hukum
Der vorliegende Band Genesis, herausgegeben von Stefan Schorch unter Mitwirkung von Evelyn Burkhardt, Ulrike Hirschfelder, Irina Wandrey und József Zsengellér, ist der erste der fünfbändigen kritischen Ausgabe des Samaritanischen Pentateuchs (SP). Dieses neue Standardwerk schließt eine Lücke der dringendsten Desiderata der Pentateuchforschung. Denn mit Ausnahme von Galls veralteter und unvollständiger Ausgabe, gab es bis dato keine kritische Ausgabe des SP. Der Band Genesis folgte zeitlich drei Jahre nach Erscheinen des dritten Bandes, Leviticus im Jahre 2018. Die Textvariante, die die Samaritaner als autoritativen Referenztext der Torah wählten, ist bis auf einige typisch samaritanische Varianten keine samaritanische Neuerfindung, sondern Zeugnis einer populäreren Textfassung der Torah als der masoretische Text (MT). Dem SP liegt zuallererst eine populärere, prä-samaritanische Version zugrunde, dessen Varianten teils in anderen Übersetzungen der hebräischen Bibel belegt sind, wie z.B. aus der griechischen Übersetzung, der sogenannten Septuaginta (LXX), den Pentateuchtexten aus den Höhlen von Qumran und den aramäischen Targumim. Der SP unterscheidet sich nicht nur vom masoretischen textus receptus durch Varianten aus den Bereichen der Paläographie, Orthografie, Text und Textauslegung, sondern auch durch Variationen innerhalb der samaritanischen Tradition selbst, da es keinen absoluten samaritanischen textus receptus gibt. Im dreisprachigen Vorwort Deutsch, Englisch (ix-xvi) und Hebräisch weist Schorch auf die Problematik und Schwierigkeiten dieser, seit 2007 vom DFG geförderten, Neuedition hin. Es folgen die Dankworte unter namentlicher Erwähnung seiner wissenschaftlichen Mitarbeiter und des gesamten beratenden und helfenden Teams. Das Vorwort schließt mit einer Hymne des samaritanischen Poeten Marqe aus dem 4. Jh. über die ursprüngliche Schöpfung, wo aus dem Reich der Güte still die Saat der Worte und Neuschöpfungen aufging. In der ebenfalls dreisprachigen Einführung (Kap. 1), bietet Schorch einen Überblick über die Geschichte der wissenschaftlichen Erforschung des SP und bisherigen Ausgaben des SP (xvii). Die Samaritanerforschung begann im 17. Jh., als Pietro della Valle in Damaskus eine samaritanische Handschrift erwarb, die er nach Paris vermittelte. Dieses Manuskript wurde in den Polyglotten von Paris (1632) und London (1655-1657) abgedruckt und somit erstmals einem breiteren Publikum zugänglich gemacht. Ca. 250 Jahre später erstellte August Freiherr von Gall eine leider mangelhafte Ausgabe des SP (Der hebräische Pentateuch der Samaritaner, Gießen 1914-1918). Es folgten diverse Ausgaben des SP, wie jene von Abraham Tal und Synopsen von Abraham Tal und Moshe Florentin, sowie die jüdisch-masoretische und samaritanische Synopse von Abraham und Ratzon Sadaqa. In Kap. 2 wird die vorliegende editio maior in mehreren Unterkapiteln beschrieben. Die Ausgabe basiert auf den ältesten erhaltenen samaritanischen Pentateuchhandschriften mit Berücksichtigung sämtlicher Varianten und Variationen. Der laufende Bibeltext wird in hebräischer Quadratschrift, die Kapitelbezeichnung und Kolumnentitel, sowie die Schreibernotiz am Endes des Buches in samaritanischer Schrift wiedergegeben. Nicht-samaritanisch ist auch die in masoretischen Texten übliche Kapitel-und Verszählung. Zusätzliche Verse gegenüber dem TM werden mit der Zahl des vorangehenden Verses und nachgestellten Kleinbuchstaben angegeben. Kapitel 2.1. widmet sich dem Haupttext der Edition. Der Referenztext der vorliegenden Edition basiert auf der Handschrift Ms. Dublin, Chester Beatty Library, 751, die im Jahre 1225 vom Schreiber Abi Barakata angefertigt wurde. Sie wird mit dem Siglum D 1 bezeichnet. In Kap. 2.2. bis 2.3.5. werden die fünf Apparate beschrieben, welche die Variantenlesungen und Querverweise von 23 weiteren Handschriften berücksichtigen. Sie umfassen 1. den zur Grundschrift abweichenden Konsonantentext; 2. Belege aus dem samaritanischen Targum und den samaritanisch-arabischen Übersetzungen; 3. Textkritische Zeichen und Vokalzeichen; 4. Textparallelen aus den Qumranhandschriften, der LXX, Peschitta Vulgata und den jüdischen Targumim; 5. Interpunktionszeichen wie z.B. das qitza-Zeichen (-:) am Ende von Textabschnitten. Die Apparate und ihre Sigla erscheinen auf den ersten Blick ziemlich kompliziert, sind aber gut erklärt und durch Beispiele verständlich gemacht. Zuletzt (2.3.6.) werden die Marginalnoten zur samaritanischen Vokalisierung erklärt. Die Lesetradition basiert auf der jahrhundertealten mündlichen Tradition, die manchmal mehrdeutig und nur durch das samaritanische Textverständnis und die Übersetzung ersichtlich ist. Hierfür hilfreich ist die englische Übersetzung des SP von Benyamim Tsedaka (Hg. und Übersetzer) und Sharon Sullivan (Hg.), The Israelite Samaritan Version of the Torah: First English Translation, Grand Rapids 2013. Was vielleicht stärker betont werden sollte ist, dass die Lesetradition der Samaritaner völlig anders ist als die jüdisch-masoretische. Auch gibt es kein konstant appliziertes Vokalisierungssystem vergleichbar dem masoretisch tiberiensischen oder babylonischen System. Die Einführung wird durch ein Abkürzungsverzeichnis, eine Zeichenerklärung, dem samaritanischen Alphabet und einer Bibliografie abgerundet. Abschließend sei dankend bemerkt, dass Schorch und sein Mitarbeiterteam mit dieser editio maior ein unumgängliches Werk geschaffen haben für jeden Pentateuchforscher und Bibelwissenschaftler, der die biblische Textgeschichte in seiner Vielfalt ergründen will. Die schon vorliegenden Bände Genesis und Leviticus vermitteln einen hervorragenden Einblick in den SP und lassen auf die folgenden Bände dieses neuen Standardwerkes hoffen, die weit über die Besonderheit des samaritanischen Pentateuchs hinaus wertzuschätzen sind und dem SP die gebührende Aufmerksamkeit zusichert. Denn der samaritanische Texttypus ist nicht nur philologisch von großer Bedeutung, sondern auch exegetisch höchst interessant und ein privilegierter Textzeuge der pluralen Gestalt des Bibeltextes der hellenistischen und römischen Epoche und ein Brückenschlag zu den aus Qumran, der LXX, den Targumim und anderen alten Texttraditionen.
When Donald Trump joined the international media circus of politics, first as the Republican candidate and then as the President of the US, his original hair style stirred a widespread curiosity. Then Trump appeared side by side with the North Korean leader Kim Jong-un, also the bearer of a very different yet equally unconventional hairdo. The pair formed such a suggestive diptych that I thought the powers of semiotic analysis should be summoned to inquire on that rare and relevant juxtaposition. The present article summarises the outcomes of that analysis. The conclusion suggests that Trump's hair represents a kind of 'autism in self-presentation', while in Kim's case the separation extends to his culture as a whole. In conclusion, the combined consequences of these characteristics of the two personalities lead to the hypothesis that the dialogue they have undertaken may remain less a true substantial confrontation than a mere display of contact.
