In this class, we discuss algorithms that use for speeding up systems for information security and privacy. Particularly, the class focuses on algorithms for elliptic curve cryptography, one of the most well-known cryptographic system. We also explain ideas behind discrete algorithms that can protect users’ personal information in large-scale database. 本授業には、情報セキュリティ・情報プライバシーを保護するシステムを最速するアルゴリズムについて講義する。特に、セキュリティ技術の代表になっている楕円曲線暗号の実装アルゴリズムについて議論し、巨大データベースに入っている個人情報を保護する離散アルゴリズムを解説する。

Science and technology studies (STS) is an interdisciplinary approach to the study of science and technology (S&T) and their relationship with human beings and the societies, polities and cultures they inhabit. The course thus explores the central – if not determining – role of S&T in modern societies by providing a critical analysis of the philosophical, sociological, political, economic and ethical conditions and choices they confront us with.

This lecture series provides an overview of what the academic genre of ethnography has achieved over the past century or so. Although ethnographic monographs have also been written by scholars of various disciplines, this lecture series focuses on sociocultural anthropologists’ endeavors. Rather than discussing the possibilities and limitations of ethnography abstractly, the aim of this course is to provide a perspective on what an ethnography have (and have not) accomplished, by discussing critically two or three ethnographic monographs, many but not all of which are in the context of Asia, each time, both locating them in academic and social contexts of the time and and relating them to various ongoing debates.

広く産学官にわたってグローバルに活躍するために必要な「俯瞰力」を養成することを目指す。物質科学の各分野について最先端の知識を修得し、自分の専門分野と周辺分野がどのように関連するか、あるいはし得るか、について深く考察するために、第一線で活躍する講師の方々にその分野の最前線を概観していただく。さらに、それらの講義を通して異分野間のコミュニケーションを円滑に進めるための具体的方法論を学ぶ。 This survey course is designed to enable students to develop the broad perspective that is required of global leaders working in and across industry, academia, and government. Students will gain knowledge and insight on advancements in each field of materials science research, given by leading researchers working on the frontline in those fields. This will allow students to consider how peripheral fields are related to their own area of expertise, and to consider the potential for forging bridges between related fields in the future. In addition, students will learn specific methodologies designed to facilitate smooth communication among different disciplines.

This is a course on visual culture in the 20th and 21st century, with a particular focus on the interplay between media technology, culture and society. This course will also be multidisciplinary in nature, as we reflect on our discursive assumptions in the historical, sociological, anthropological, philosophical disciplines among others. While the readings may primarily cover phenomenon in the United States, participants will be strongly encouraged to think of the specificity of the impact of globalization on media and society in various regions of the world including Japan. The course objectives are the following: -Gain a better understanding of the relationships between society, media, people, institutions and how they function as agents of maintaining the status quo or for fostering change -Learn about the transformative faculties and social implications of quotidian applications of technology -Gain deeper understanding of the academic disciplines Topics will include (but are not limited to): -representation of race, ethnicity and gender and other minorities -regional, transnational and international ecosystems of information technology -artificial intelligence and algorithmic bias -technological advancement and implementation in everyday life and the powers at play

This course provides a critical and interdisciplinary overview of the major legal and political developments that have shaped - and continue to shape - Japanese society. Drawing on perspectives from political science, law, history, and sociology, the course emphasizes both top-down and bottom-up processes in Japanese governance. It focuses on how law operates within society, particularly through constitutional, criminal, and civil law. However, the aim is not to analyze these laws in isolation, but to explore how they function within the social fabric of Japan. Law is a fundamental aspect of everyday life in all societies: it provides predictability, helps avoid anarchy, and secures cooperation among members of society by prioritizing the common good over individual gain (law as a tool for stability in society). Law is also a tool for action when people or groups feel excluded, discriminated against, or believe they are being treated unjustly (law as a tool for social change). This course examines the central features of Japan's legal system, viewing law as a social institution and exploring its relationship with other societal systems. We will focus on the role of key actors in the legal system and the interplay between social stability, and change. Additionally, the course emphasizes the relationship between law and broader economic, political, and social processes. From the perspective of the sociology of law (or socio-legal studies), we will examine how law serves as both a practical resource for addressing social issues (a tool for change) and a set of shared representations and aspirations (for stability). The course will explore how legal professionals (lawyers, judges, law enforcement officers) and ordinary citizens mobilize and use law. Due to time constraints, we cannot cover every aspect of Japan’s legal system or every actor involved. Instead, we will focus on key topics that illustrate the situational and systemic demands placed on actors within the legal system. At the same time, we will seek to identify patterns in how law interacts with and influences society. Some of the topics we will address include Japan’s exceptional record in economic development, crime control, and its low litigation rate. These topics exemplify why Japan's legal system is so efficient; not only by examining how it functions today, but also by tracing its historical roots and understanding why it evolved in this way. We will also address topics such as the death penalty, wrongful convictions, same-sex marriage, and other areas of social activism where law is used to drive social change. These topics reflect the "reverse side of the coin," where law may not function effectively, and social activism seeks to change the situation. In sum, we will analyze the actual evolution of the rule of law in both the past and present, with an eye on the future of Japan and its place in a globalizing world. Therefore, this course combines methodologies from the sociology of law and legal history. We will also critically assess the limitations of law in Japan, asking which social issues remain unresolved by the legal system. Is Japan’s legal system an example for other countries to follow, or not? Ultimately, the goal is to critically examine both the merits and flaws of Japan's legal system in an informed and balanced manner. By studying how conflicts are resolved, how social order is maintained, how movements for social change emerge, and how legal frameworks operate within Japan’s socio-political context, students will develop a comprehensive understanding of Japan’s legal system from the Meiji era (1868–1945) to the present day. Each class will begin with a methodological introduction, providing students with tools from the sociology of law, followed by the analysis of primary materials (e.g., court decisions, political speeches, legislative texts, personal diaries) and secondary readings that offer academic context.

This course aims to help students engage with the key theories and methodologies used in affect and sensory studies and critically assess whether—and how—these fields contribute to expanding and deepening existing scholarly knowledge.

The primary goal of the course is to provide students with an integrated view of how the basic concepts of mathematics and physics are applied to collecting information about a system. Upon successful completion of this course, the student will have: -acquired a basic knowledge of the physics of information, -gained an understanding of the physical principles of a broad range of modern sensors, -developed skills in data analysis and system modeling.

In this course, students learn about STS (Science, Technology and Society) through case studies. What is this called science? How can we manage the conflicts between S&T and Society? Who are the experts? These questions appear in various issues around us, such as the pandemic of COVID-19, environmental problems, disasters, and governance of emerging technologies. In this course, we learn about, and discuss cases from STS perspectives. Students are required to do their own case analysis in their final report.
