What is called "American feminism" in this article means liberal feminismor radical feminism. Many critics, especially French ones such as ElizabethBadinter and Emmanuel Todd, underestimate American feminism in the pointthat its pro-violence tendency hinders feminism from its mature developmentand further prevalence. This article does not share their view. As explainedlater, the pro-violence attitude of American feminism might be able to present aprototype of "a citizen of the world" in the coming (?) borderless, post-nationstatesworld promoted by globalization. Here "globalization" does not mean thelatest stage of American imperialism. Here globalization is "the process of increasinginterconnectedness between societies such that events in one part ofthe world more and more have effects on peoples and societies far away."It is true that not a few of American feminists regard violence as one of theiroptions to protect themselves. American radical feminists such as Naomi Wolfand D. A. Clarke assert that women should not hesitate to counterattack againstdomestic violence and other sexual violence. Paxton Quigley recommendswomen's owing guns against crimes. Martha McCaughey, a physical feminist, advocateswomen's going into training in martial arts for self-defense. The NationalOrganization for Women (NOW), which is a representative of liberal feminists inUSA, is positive about woman soldiers' service in war battles for national defense.Yet they are not especially pro-violent, because their attitude is necessarilyresulted from American core values.Some American feminists regard their position as "militia" or contemporarycitizen soldiers. Militia is a military force that engages in a rebel or terrorist activitiesin opposition to a regular army. Militiamen, ordinary people with theirown guns used for their hunting for food (never for pleasure) won the victory inthe American War of Independence, though some researches say that it is nothingbut a myth, not a historical fact. Myth or fact, in this point, militia symbolizesAmerican core values : freedom, independence, individualism, equality and democracy.Once American people feel that their "unalienable Rights, that amongthese are Life, Liberty and the pursuit of Happiness" are threatened by others,governments or any organizations or individuals, they might be ready to use theirown weapons. Weapon ownership is a key aspect of citizenship under democraticgovernment for some American people. They believe that the Constitution ofthe United States of America supports their view.Certainly Amendment 2 of Bill of Rights enacted in 1791 says "A well regulatedMilitia, being necessary to the security of a free State, the right of the peopleto keep and bear Arms, shall not be infringed." The survey of ABC News in2002 shows that seventy three percent of the American citizens think thatAmendment 2 guarantees their right to keep and bear weapons for self defense.American people against gun control are not only what antigun critics call "gunenthusiasts." According to one research, gun owners believe that society is aviolent place; so they prepare for the possibility of doing violence themselves ;they view this position to be the most responsible one they have to take in relationto their own safety ; they are also aware that many oppressive governmentsdo not permit firearms to be owned by the general people, because gun ownershipcan potentially threaten the government through a citizens' revolt. SomeAmerican feminists share this view with gun owners.This article does not mean that American feminists' pro violence attitudeshould be positively considered because their views are resulted from Americancore values. Even if American feminists regard themselves as militiawomen,contemporary citizen soldiers, such kind of attitude can be called caricatural.There is a hypothesis that the peripheral members in a given society try to moreradically embody the society's most sweeping ideologies than the central members.American feminists who try to be regular citizens, never "second citizens",may be more stimulated to achieve American core values as completely as possible.We should notice that this kind of caricatural American feminists providesus with a prototype of a citizen of the coming world developed by globalization,where order in world politics emerges not from a balance of power among nationstatesbut from the interactions between many layers of governing arrangements.Nation-states demand its constituency to be subject to their policies andlaws, and in exchange for its subordination, they are supposed to offer their peoplebenefits and protection. But history has been showing the examples thatnation-states could be the worst oppressor and violator for people. However,globlization might permit people to traffic the many layers of governing institutions,depending on their own needs and profits. Then, nation-states will be ableto be optional, not fatal.The political philosophy of the coming, globalized world is the most radicalform of republicanism, also called civic humanism. The coming world might beable to be the most expanded republic, a new world order governed by and forthe people. Then, people will not be able to rely on nation-states as their protectors,if people don't want state interference. In other words, future citizens ofthe world must be ready to be citizen soldiers, caricatured form of militia,"American feminists." As citizens of a republic, American feminists who premisethat they can't trust the government and its agents, do not invite the state to beresponsible for their safety, even though dependency is so seductive.Some people wonder if such a world can be the greatest prison, the mostelaborate "Matrix" controlled by invisible power. Whether the biggest republic,the new world order may be utopian dystopian, a pro-violent, pro-counterattackAmerican feminist is a prototype of a citizen of the post-nation-states world.

缶入りコーンポタージュスープは、冬場の缶入りスープとして定着しており、幅広い年代の人に飲用されている。しかし、飲用後に缶内に粒コーンが残留し、粒コーンを全て飲み干すことができない、というユーザビリティ上の問題ある。この問題に対して、缶形状の改良やスープ粘度の調整などが提案されている。しかし、これら従来の研究では、本来注目すべき飲用時におけるユーザ動作に関して十分な解析がなされていない。そこで本研究では、飲用時におけるユーザ動作の人間工学的な解析を行い、飲用後の粒コーンの残留要因を明らかにした。まず、飲用時のユーザ動作の特徴と残留コーン数の関係を29 名の被験者実験によって明らかにした。この結果、残留コーン数は、種々のユーザ動作の特徴の中で、ユーザが何回に分けてスープを飲用するかの回数(以下では「飲む回数」)と強い相関(相関係数R=0.82)があることを見出した。さらに、この「飲む回数」とそのときの「缶の傾斜角度」を用いて模擬的な動作パターンを作成し、これを用いることで、被験者実験を行うことなく、残留コーン数に対するユーザ挙動を再現できることを示した。次に、缶内の粒コーンの挙動を観察するため、可視化を行った。金属缶は透明樹脂により透明化し、スープに関しては、ほぼ同一の粘性・密度を持つ透明液で置き換えた。これによって、飲用時における粒コーンの動きを観察可能にした。最後に、上記の模擬的な動作パターンを可視化した缶・スープで実行することにより、飲用時に粒コーンが残留する主要因は、飲み口の段差に粒コーンが引っかかってしまうことであることを実験的に明らかにした。

To tackle financial crimes including fraudulent financial transactions (FFTs), money laundering, illegal money transfers, and bank transfer scams, several attempts have been considered to employ artificial intelligence (AI)-based FFT detection systems, particularly, deep learning-based ones. However, to the best of our knowledge, no federated learning systems using real transaction data among financial institutions have been implemented so far. This is because there are several issues to be addressed as follows: (1) it is difficult to prepare sufficient amount of transaction data for training by one financial institution (e.g., a local bank), and a small amount of dataset does not promise high accuracy for detection, (2) each transaction data contains personal information, and thus it is restricted by Act on the Protection of Personal Information in Japan to provide the transaction data to a third party. In this paper, we introduce out demonstration experimental results of privacy-preserving federated learning with five banks in Japan: the Chiba Bank, Ltd., MUFG Bank, Ltd., the Chugoku Bank, Ltd., Sumitomo Mitsui Trust Bank, Ltd., and the Iyo Bank, Ltd. As the underlying cryptographic tool, we proposed a privacy-preserving federated learning protocol which we call DeepProtect, for detecting fraudulent financial transactions. Briefly, DeepProtect allows parties to execute the stochastic gradient descent algorithm using a set of techniques for the privacy-preserving deep learning algorithms (IEEE TIFS 2018, 2019). In the demonstration experiments, we built machine learning models for detecting two types of financial frauds ― detecting fraudulent transactions in customers/victims' accounts and detecting criminals' bank accounts. We show that our federated learning system detected FFTs that could not be detected by the model built using the dataset from a single bank and detected criminals' bank accounts before the bank actually froze them.------------------------------This is a preprint of an article intended for publication Journal ofInformation Processing(JIP).

妊娠中の腰痛はマイナートラブルとされているが、妊婦の多くが腰痛を経験していることから、避けられない問題であると考えられる。本研究の目的は、先行研究で採用した前額面の姿勢アライメントと腰部脊柱起立筋の筋硬度と腰痛について、妊娠中から出産後の変化パターンを明らかにすることである。対象群は、初産婦26名とコントロール群11名であった。その結果、①妊娠34週で腰痛を訴える人が増加するがその後有意に変化しない、②腰痛部の罹患は産前産後を通して変化しない、③仙腸関節周辺部痛の罹患と骨盤の水平方向への開きは、妊娠36週に増加し出産後1ヶ月で減少するパターンを呈する、④筋硬度は妊娠後期に左右非対称に高くなり、出産後約1ヶ月まで継続することが明らかとなった。出産後の女性の身体状況の回復には約1ヶ月かかると考えられることから、出産後の生活を考慮した指導を妊娠中に実施する必要があることが示唆された。

This study examines how oni, demon-like creatures of Japanese folklore, are expressed in the popular Japanese comic series “Kimetsu no Yaiba” by Gotouge Koyoharu serialized in Weekly Shonen Jump from 2016 to 2021 by applying a framework called Monster Theory. The publication of this theory advocated by Jeffrey Jerome Cohen and made up of seven theses regarding the nature of monsters, marked the beginning of a surge in popularity of studies and research related to monsters in Europe and the United States and is a theory that attempts to clarify the meanings of monsters that appear in various modern media creations. Previous studies have shown that the presence of monsters has been useful as an indicator of social normative and non-normative distinctions, but such analyses have been primarily focused on the explication of literature and cinema. In this study, I would like to provide an example of the application of monster theory to the graphic narrative format-specifically the medium of Japanese comics. As “Kimetsu no Yaiba” provides nuanced expressions of oni, monsters that have a long history in Japan and are tied intimately to various aspects of Japanese culture past and present, it will serve as a worthy example of a robust application of the Monster Theory framework to the graphic narrative format. Through such application, I would like to develop a deeper understanding of the psychology that society has toward the self and the Other and uncover examples of alternative viewpoints within the work related to the attitudes the author thinks people should hold in regard to the self and those Others.First, I will give a short introduction to Monster Studies and Monster Theory and its applications, especially to the medium of comics. Then I will discuss the evolution of the monster’s role in society and the history of oni in Japan. After describing typical perceptions of oni and traditional representations of oni in Japanese comics, I will delve into how the main characters and oni of “Kimetsu no Yaiba” provide clear examples of several aspects of Cohen’s Monster Theory, and I will give examples that relate to each of the seven theses contained within the Monster Theory framework to expose the potential of the work as a tool for developing new more nuanced attitudes toward the self and the Other.

宮沢賢治の有名な物語「銀河鉄道の夜」は、銀河鉄道の旅の部分が幻想的であるが、中で異質で写実的な部分が「プリオシン海岸挿話」で、白鳥の停車場での停車時間中に主人公のジョバンニとカムパネルラが化石の発掘現場を見てくる話である。旅中で唯一の途中下車で、モデルとなった出来事や場所が特定でき、この挿話を含む章には「北の十字架」と「プリオシン海岸」という二つの異なるテーマが収められ、章題も不自然に長くなっており、少年たちの言動が他の部分に比し大人びている、など多くの点で異質である。それらのことから、この挿話は元来は夢の旅の原稿とは別に書かれた独立の短編がのちに「銀河鉄道の夜」の中に挿入された部分であることがわかった。

本稿の目的は,警察,死体検案医,解剖担当者による自死遺族支援の可能性を検討することである.検討の結果,警察が自殺を装った殺人を疑うことが自死遺族を大きく傷つけていること,検案費用や解剖費用,検案書発行手数料の請求に明確な規定がないこと,検案医や解剖担当者が実施内容や結果について遺族への説明責任を果たしていないことなどが自死遺族の死別後の苦しみをさらに増大させている恐れがあることが分かった.警察は犯罪被害者支援の経験を活かし現場での支援実施責任者として自死遺族に特化した明確な支援を提供できること,検案医と解剖担当者は機転を利かせ積極的に警察と相談の上,遺族に結果を紳士的に説明し自死遺族に特化した支援を提供するなど,欠くことのできない重要な役回りを果たすことができることを指摘した.
