A New Trend of In-situ Electron Microscopy with Ion and Electron Beam Nano-Fabrication

Furuya, Kazuo,Tanaka, Miyoko Korean Society of Electron Microscopy 2006 Applied microscopy Vol.36 No.2

Nanofabrication with finely focused ion and electron beams is reviewed, and position and size controlled fabrication of nano-metals and -semiconductors is demonstrated. A focused ion beam (FIB) interface attached to a column of 200keV transmission electron microscope (TEM) was developed. Parallel lines and dots arrays were patterned on GaAs, Si and $SiO_2$ substrates with a 25keV $Ga^+-FIB$ of 200nm beam diameter at room temperature. FIB nanofabrication to semiconductor specimens caused amorphization and Ga injection. For the electron beam induced chemical vapor deposition (EBI-CVD), we have discovered that nano-metal dots are formed depending upon the beam diameter and the exposure time when decomposable gases such as $W(CO)_6$ were introduced at the beam irradiated areas. The diameter of the dots was reduced to less than 2.0nm with the UHV-FE-TEM, while those were limited to about 15nm in diameter with the FE-SEM. Self-standing 3D nanostructures were also successfully fabricated.

This study aims to improve the machinability of gray cast irons in high speed cutting by using nonmetallic inclusions. In this research, small quantities of AL and Mg were added to conventional gray cast irons without influencing their mechanical characteristics and castability to investigate the effects of these nonmetallic inclusions in the gray cast irons on tool wear in high speed cutting. During the high speed turning of gray cast iron containing Al and Mg using a cermet tool, protective layers consisting of Al, Mg, Si, Mn, S and O were detected on the flank face and rake face of the tool, and flank and crater wear were significantly reduced compared to the turning of conventional gray cast iron and gray cast iron added with Al. The effect of inclusions on tool wear increased with increasing cutting speed, and flank and crater wear was the smallest at the cutting speed of 700m/min. Moreover, in face milling, the addition of Al and Mg drastically decreased the wear rate, and wear hardly progressed even in prolonged cutting length after initial wear. The amount of adhesion on tool faces increased as the cutting speed increased. This increase in cutting speed resulted in the formation of a thick protective layer and the reduction of tool wear. Furthermore, the addition of small amounts of Al and Mg prevented thermal cracks in the face milling of gray cast irons.

A reconsideration of the (non-)uniform syntax of Korean right-dislocation

Kaori Furuya 경희대학교 언어정보연구소 2018 언어연구 Vol.35 No.2

This paper investigates the clausal natureof Korean Right-Dislocation Constructions (RDCs) and reconsiders recent extant (non-)uniform analyses of RDCs. Since Korean is a pro-drop language, most of the literature on Korean RDCs assumes the preverbal empty category as pro or a trace out of movement in the constructions. However, recent literature has shown that null arguments can also be derived via argument ellipsis (e.g. Sakamoto 2016). The paper identifies the categorial statuses of preverbal empty categories and demonstrates similarities and differences between gapped and gapless RDCs that Ko (2016) and Ahn and Cho (2016, 2017) do not observe. It argues that a non-uniform analysis is most compatible to account for the distribution of empty categories of RDCs. The proposed analysis receives support form novel evidence based on (non-)parallelisms between RDCs and fragment answers.

Domestic Implementation of the Rome Statute in Japan

Shuichi Furuya 서울국제법연구원 2015 서울국제법연구 Vol.22 No.2

When Japan acceded to the Rome Statute on July 17, 2007, it enacted the “Act on Cooperation with the International Criminal Court”. However, the present Act aims at ensuring procedural cooperation with the ICC, and does not set out new substantive provisions nor change existing Penal Code in order for Japan to try and punish the perpetrators who commit the crimes referred to in Article 5 of the Rome Statute. From the consideration that there was “no need to think about unthinkable things” and enacting a comprehensive law to criminalize every act and omission would delay the accession to the Rome Statute, Japan adopted a “minimalist” approach according to which a State Party does not change substantive criminal law and domestically punish the crimes within the Rome Statute as far as its existing laws are applicable. In fact, most of the conducts constituting the crime of genocide, crimes against humanity and war crimes constitute ordinary crimes under the Penal Code of Japan if they are committed in the territory of Japan. However, the crimes within the jurisdiction of the ICC, save war crimes as grave breaches, cannot be tried by a Japanese court if they are committed by foreigners against foreigners outside the territory of Japan. In terms of those crimes, Japan would have to entrust the prosecution and punishment of perpetrators to the ICC pursuant to the principle of complementarity. In contrast, the Cooperation Act, with taking into account a vertical relation between the ICC and a State Party, prescribes in detail the ways of cooperation with the ICC such as the procedures of surrender, production of evidence and enforcement.

大學における對話の場づくりとしての 自律的日本語學習の支援 - 「わせだ日本語サポ一ト」を事例とする考察 -

古屋憲章 ( Furuya Noriaki ) 한국일어교육학회 2018 일본어교육연구 Vol.0 No.43

本硏究の目的は、「わせだ日本語サポ一ト」(以下「サポ一ト」)を事例として、自律的日本語學習(學習者オ一トノミ一)の支援を對話の場づくりとして位置づけることである。そのため、本稿では、まず、2節において、「サポ一ト」がどのように實施されているかに關し、「サポ一ト」の實施形態、利用狀況、(「サポ一ト」實踐の軸である)日本語學習アドバイジングを中心に說明した。次に、3節において、「サポ一ト」スタッフが自身の「サポ一ト」實踐の經驗や學習者へのインタビュ一をとおし、どのような氣づきを得たかを記述した。そして、4節において、アクションリサ一チ(AR)の樺組みに卽し、本硏究を省察したうえで、省察にもとに、「サポ一ト」を對話の場という觀点で考察した。 考察の結果、次のような「サポ一ト」の內實が明らかになった。a)「サポ一ト」スタッフは、ARにおけるアクションリサ一チャ一であり、「サポ一ト」利用者(日本語を母語としない學生)は、ARにおける硏究協力者である。b)「サポ一ト」は、アクションリサ一チャ一であるスタッフと硏究協力者である利用者が大學における敎室外日本語學習環境をめぐり、對話する場である。c)「サポ一ト」におけるスタッフと利用者の對話をとおし、大學における敎室外日本語學習環境が協動的に構築されるとともに、改善される。d)「サポ一ト」という協動的な實踐が、大學における對話の場づくりとして機能している。さらに、a)~d)の考察をふまえ、大學における對話の場づくりとしての「サポ一ト」が、日本語敎育の想定する「ことばと社會」の公共性を提案していく實踐硏究、すなわち公共日本語敎育學の實踐となっていく可能性が示唆された。 The purpose of this research is to position support of autonomous Japanese learning (learner autonomy) as creating a place for dialogue as a case of 'Waseda Nihongo Support' (hereinafter 'support'). First, Section 2 of this study discusses the implementation of 'support', the situation of use, the language learning advising (which is the axis of 'support' practice) about how 'support' is implemented it explained to the center. Next, Section 3 discusses what kind of awareness the 'support' staff got through their experience of practicing 'support' and interviews with learners. Then, in accordance with the framework of action research (AR), after reviewing this research, Section 4 examines 'support' from the perspective of dialogue based on reflection. The result of this study shows the following 'support' structure: a) 'Support' staff is an action researcher in AR, 'support' users (students without native Japanese) are research collaborators in AR, b) 'support' is a place where the staff who is an action researcher and the user who is a research collaborator can talk with each other around the university Japanese language learning environment at the university. c) Through dialogue between staff and users in 'support', the Japanese language learning environment outside the classroom at the university is collaboratively constructed and improved. d) Collaborative practice 'support' is functioning as a place for dialogue at university. Furthermore, based on the consideration of a) to d), 'support' as creating a place for dialogue at university is a practical research proposing the public nature of 'language and society' assumed by Japanese language education, that is, practice of public Japanese language education, inspiring the possibility of becoming an academic practice.
