We proposed a Sontag-type feedback controller by using a locally semiconcave practical control Lyapunov function (LS-PCLF) for asymptotic stabilization of a nonlinear system defined on a non-contractible manifold. We also proposed a design method of a nonsmooth control Lyapunov function called the multilayer minimum projection method. However, whether the method can be used as an LS-PCLF design method is not discussed, and we cannot design a controller by using the method and the controller in this situation. In this paper, we study a disassembled differential of a locally semiconcave function to handle an LS-PCLF. The minimal and maximal disassemble differentials, which are special types of a disassembled differential, are introduced. We elucidate that a set of reachable gradients and the Fréchet differential are equivalent to the minimal and maximal disassembled differential, respectively. Based on this fact, we prove that this method can be used as an LS-PCLF design method.

The present article reviews borderline personality traits in a non-clinical population. Studies conducted in Japan on this topic have drawn their samples from either subclinical populations or adolescents known to be mentally unstable. Adolescents with a high level of borderline personality traits have many difficulties in interpersonal relations as well as family conditions. Many studies from other countries have examined borderline personality traits in non-clinical populations. These studies have revealed the following: (1) Borderline personality traits have some clinical features. (2) Individual with borderline personality traits typically lack skills in managing and understanding emotions. (3) Significant multivariate predictors and risk factors of borderline personality traits exist. (4) Borderline personality traits predict negative outcomes in academic and occupational achievement. This paper reveals that future studies are needed to better understand the etiology, development, and course of borderline personality traits, and shows how longitudinal research and case studies can support existing findings.

本研究では, 従来青年期心性の特徴として指摘されてきた複数の視点に加えて, 対人関係における葛藤的側面といった視点を導入し, 「境界例心性」として位置づけた。質問紙調査を通じて, 青年期における境界例心性の構成要素を見いだし, 各成分間の関係を図示した。さらに境界例心性に与える両親の養育態度の影響を検討した。<BR>予備調査では, 青年期における境界例心性の全体像を把握するために, 境界例の診断基準に基づいて独自に作成した質問項目を用いて大学生を対象に調査を行った。その結果, 青年期における境界例心性は, 感情・衝動コントロールのできなさや非現実感よりも, 対人関係における敏感さや孤独感, 不安定な自己像や抑うつ感, 自我同一性の欠如によって構成されていることが示された。本調査では, 大学生・専門学校生を対象に調査を行い, 予備調査で明らかとなった境界例心性の側面をより詳細に検討することを試みた。対人関係における敏感さや葛藤的な感情については, 予備調査で使用した質問項目を再構成し, 独自に尺度を作成し, 「対人関係における境界例心性尺度」と命名した。抑うつ感と自我同一性に関しては既存の尺度を用いた。これら3尺度間の関連を検討した結果, 青年に内在化された境界例心性の構成要素が同定されるとともに, 発達の一側面としての特徴が明らかになった。また, その構成成分から, 青年期における境界例心性と, 精神障害としての境界例との共通点と異なる点が示唆された。さらに青年期の発達過程における内的葛藤状況が, 他者との関係の中の揺れとして示される点が, 青年期独自の境界例心性の特徴として捉えられた。<BR>両親の養育態度との関連を通して, 性別を問わず, 特に心理社会的同一性の確立に与える両親の養育態度の重要性, ならびに自己・他者・社会に対する一貫した自己像の確立に与える母親養育態度の重要性が示唆された。また青年期の女性における父親の養育態度の影響力の強さが明らかとなった。

This paper reveals the mechanisms of price formation, governance structures, and effects on the production area (especially of farming household management and food crops)in the current “second and half (2.5)stage of globalization on coffee” that are classified according to the theory of food regimes, using the example of Kilimanjaro coffee grown in Tanzania.This study focuses on six stages of price formation from production to consumption. First, we unravel the mechanisms of price formation based on the analytical framework of the food system (particularly “chain structure” and “competition structure”)introduced by Niiyama, and we discover the lead firms and governance structures of the food system, analyzed using the Global Value Chain (GVC)theory. Then, we evaluate the results of price formation and governance structures by incorporating analyses of the difference and unevenness in the size and values (gross income)/margins (net income)introduced by the GVC theory.Furthermore, this paper positions fair trade as a means of upgrading (securing and tacking on income and added value)the production area in the GVC theory and explores its effects. Fair trade involves corporations selectively accepting the demand of social movements as a procurement standard, which are also a characteristic of “2.5 stages of globalization on coffee.”Finally, we discover that payment made by consumers remains in consumer countries, notably when the producer price of coffee is curbed by the governance structures of an international trader-driven type up stream, a speculator-driven type in the middle, and a buyer-driven type downstream of the food system. The mechanism in which payment made by consumers of a fair trade coffee for supporting producers flows back to the producers is also found out.

デジタルアーカイブの目的として「文化の次世代への正しい継承」ということがしばしば言われる。しかし、文化が変化を前提としていると考えれば、デジタルアーカイブによって「次世代への正しい継承」はできず、場合によってはそれを阻害する可能性もある。また、デジタルアーカイブによる「次世代への正しい継承」という言説の背景には、研究者やデジタル技術による特定イデオロギーへの権威付けや、国家政策との関連が見出される。デジタルアーカイブは、むしろ、このような運動を相対化する方向で活用されるべきではないだろうか。``The right succession to the next generation of culture'' is often said as a purpose of digital archives. However, given that culture always changes, ``the right succession'' can not be attained by digital archives, but may be disturbed in some cases. Moreover, investigating the background of ``the right succession,'' we can find the authorization to the specific ideologies by the researchers or the digital technologies, and relation with a national policy. We suggest that digital archives should be developed and utilized in order to deconstruct such movements.

Detailed rupture processes of six intraplate earthquakes in Japan, the 1961 Kitamino earthquake, the 1969 GifuKen-Chubu earthquake, the 1974 Izu-Hanto-Oki earthquake, the 1975 OitaKen-Chubu earthquake, the 1980 Izu-Hanto-Toho-Oki earthquake, and the 1984 NaganoKen-Seibu earthquake, are compiled and compared to each other to make clear common features of an earthquake rupture process. The rupture processes are obtained by waveform inversion using strong motion seismograms in previous studies. Five of these rupture processes are also compared with distributions of precisely determined aftershocks. Earthquakes with relatively smooth rupture propagation, such as the 1974 Izu-Hanto-Oki earthquake and the 1961 Kitamino earthquake, represent smoother slip distribution than earthquakes with relatively irregular rupture propagation, such as the 1969 GifuKen-Chubu earthquake and the 1980 Izu-Hanto-Toho-Oki earthquake. It is also recognized that aftershocks of magnitude greater than 4 do not occur in the large slip area. Most large aftershocks take place near the edge of the large slip region and in the small slip region. Aftershocks also tend to cluster near the edge of the large slip region. These results are very consistent with numerical experiments of dynamic rupture, so it is suggested that the relation between aftershocks and coseismic slip pattern obtained in this paper hold generally for earthquake rupture processes. A clear delay of rupture propagation occurs in the large slip area during the 1969 GifuKen-Chubu earthquake: on the other hand, the small slip area in the 1980 Izu-Hanto-Toho-Oki earthquake is characterized by a deceleration of rupture propagation. The large slip area in the former case is interpreted as a barrier which resisted fracturing at first and was broken with a high stress drop. In the latter case, mechanical weakness due to volcanic structure located around the source region, seems to have affected the rupture process. A similar geological condition may have affected the rupture process of the 1978 Izu-Oshima-Kinkai earthquake which occurred about 10 km south of the 1980 Izu-Hanto-Toho-Oki earthquake.

Mitochondria in a live HepG2 cell were visualized with a fluorescent probe to specify their location and state in a living cell. Then, mitochondria were selectively captured with a nanospray tip under fluorescence microscope, and thousands of small molecular peaks were revealed and unique steroids specific to mitochondria were also found. This fluorescence imaging combined with live single-cell mass spectrometry opens the door to the analysis of site- and state-specific molecular detection to elucidate precise molecular mechanisms at the single-cell and organelle level.

Some molecular viewers that can visualize molecular structural data have been introduced. Those viewers can be generally classified into some categories, such as Java based, JavaScript based, WebGL based, for mobile and for PC. The Java based software that requires the Java Runtime Environment (JRE) is widely used both for a local application and an embedding one in web pages. The JavaScript based software only requires a web browser without JRE but the response speed is lower than the Java based one. The WebGL based softwares work more lightly than the formers, but I think so far there is no software with an advanced display controller such as a command interface. For mobile devices, some molecular viewers are provided from application distribution sites, such as Google Play and App Store. Many viewers for PC environment have some advanced controllers for changing expressions of molecular modeling images and drawing them in detail. As an example, a series of operating procedure scripts for creating a molecular image using a stand-alone application, called "jV", was introduced here.
