Changing Meaning of the Elderly in Nan Province, Northern Thailand: From "Khon Thao Khon Kae" to "Phu Sung Ayu"(<Special Issue>Redefining "Otherness" from Northern Thailand)

この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。In this paper, I deal with the group named "the elderly" in the guardian spirit ritual in theTai-Lue villages in Nan province, Northern Thailand. These groups appeared after thedecline of the traditional role of the elderly in the ritual, and are connected with the recentsocial situation including the national policies towards local cultures and the elderly.Village elderly carry out newly invented performances in the ritual as a new culture ofthe elderly, not transmitted from their ancestors. One can say that the role of the elderlyin the ritual has changed from that of "Khon Thao Khon Kae" (an older person who hastraditional knowledge) to that of "Phu Sung Ayu" (a person over 60 years of age, who canreceive welfare services).However these newly invented activities of the elderly in the ritual are voluntarilyinitiated by them. They have tried to find their own world of activities even in the streamof "welfarization." They are given a new arena of self-representation and activities, i. e.performing as the Tai-Lue "elderly." So they are in a sense defined by the state, but theyadapt those definitions for their own purposes

Hemopoiesis recovery of irradiated rats conjugated with normo- and polycythemic animal by aortic anastomoses.

The experiment was designed to observe the possible relation between myelopoietic and erythropoietic activities of circulating nucleated cells. Wistar rats were lethally irradiated with 60Co, 100 r once. Two days after irradiation the bone marrow cells had faded completely. At this stage animals were conjugated with normocythemic or polycythemic rats by aortic anastomoses. After conjugation the aplastic bone marrow of the irradiated animal rapidly regained its hemopoietic activity in cases having normocythemic and polycythemic partners. Active erythropoiesis and myelopoiesis were found 96 h after parabiosis in those having normocythemic partners. In animals having polycythemic partners, however, erythropoiesis was successfully suppressed. An increase in lymphoid cell numbers was found in place of decreased erythroid cells, but there was no change in the myeloid cell proliferation rate. No hemopoietic precursor cells or immature cells were found in circulating blood all through the experimental period before and after parabiosis. The data suggest that circulating nucleated cells have marked erythropoietic activity. Erythropoietic cells may be somehow related to lymphoid cells independent of myelopoietic activity.</p

Element-specific and site-specific ion desorption from adsorbed molecules by deep core-level photoexcitation at the K-edges

This article reviews our recent works on the ion desorption from adsorbed and condensed molecules at low temperature following the core-level photoexcitations using synchrotron soft x-rays. The systems investigated here are adsorbed molecules with relatively heavy molecular weight containing third-row elements such as Si, P, S, and Cl. Compared with molecules composed of second-row elements, the highly element-specific and site-specific fragment-ion desorptions were observed when we tune the photon energy at the dipole-allowed 1s→s*(3p*) resonance. On the basis of the resonance Auger decay spectra around the 1s ionization thresholds, the observed highly specific ion desorption is interpreted by the localization of the excited electrons (here we call as "spectator electrons") in the antibonding s* orbital. In order to separate the direct photo-induced process from the indirect processes triggered by the secondary electrons, the photon-stimulated ion desorption was also investigated in well-controlled mono- and multilayered molecules. The results confirmed that the resonant photoexcitation not in the substrate but in the thin films of adsorbates plays a significant role in the realization of the highly specific ion desorption

Novel 600 V Low Reverse Recovery Loss Vertical PiN Diode with Hole Pockets by Bosch Deep Trench

The performance of a novel diode with characteristic trench shape is predicted by TCAD simulation. A novel 600 V vertical PiN diode with hole pockets by the Bosch deep trench process is proposed for a better trade-off curve between reverse recovery loss and forward voltage. The reverse recovery loss is reduced to a half. In addition, the active chip size of the novel diode is reduced to two-thirds that of the conventional PiN diode in the same forward voltage. The novel diode structure is a strong candidate when the simple fabrication process under development is established.ISPSD 2016 28th International Symposium on Power Semiconductor Devices and ICs., Jun 12-16, 2016, Žofín Palace, Prague, Czech Republi

High-performance vertical Si PiN diode by hole remaining mechanism

A novel diode with a unique trench shape is predicted by TCAD simulation to have high performance. The novel 600 V vertical PiN diode with hole pockets by the Bosch deep trench process shows a better trade-off curve between reverse recovery loss and forward voltage. The reverse recovery loss is reduced by half. In addition, the active chip size of the novel diode is reduced to two-thirds that of the conventional PiN diode in the same forward voltage. Thanks to the hole pockets with an electric field in the diagonal direction, the remaining hole suppresses the surge voltage with noise for high performance. In this paper, we specially focus on the analysis of phenomenon and the noise suppression mechanism during reverse recovery. The novel diode structure is a strong candidate when developing the fabrication process after silicon trench etching is established

Possible ability of bovine follicular fluid to attract migrating bull spermatozoa

AimTo examine the potential of bovine follicular fluid (BFF) to attract bull spermatozoa. MethodsThe ability of the BFF to attract bull sperm was evaluated by observing changes in sperm migration after being placed in a cross-column chamber. The movement parameters of the heads and flagella of the sperm that were attracted to the BFF were analyzed by using the Computer Assisted Sperm Analysis system. ResultsIt was observed that 61.6% of the bull sperm migrated toward the BFF when the BFF was used at a concentration of 0.1%, but 67.2% of the sperm did not migrate toward the BFF at a concentration of 10%. Relatively larger numbers of both precapacitated and postcapacitated bull sperm migrated toward the BFF (0.1%). The ability of the 0.1% BFF to attract sperm probably affected both the normal artificial insemination (AI) fertility sperm and the poor AI fertility spermatozoa. The flagellar curvilinear ratio of the sperm winding to the 0.1% BFF was significantly higher than that of the prewinding sperm. ConclusionThese results could suggest that BFF potentially attracts bull sperm at a certain concentration, irrespective of the capacitation status of the sperm. Although the mechanism by which this attraction occurs remains unclear, these data imply that it could be related to BFF-dependent changes in the sperm flagellar curvilinear ratio.ArticleREPRODUCTIVE MEDICINE AND BIOLOGY.16(2):133-138(2017)journal articl
