Ri.k governance i. a wi.ely used framework i. natural and soci.tal ri.k management research. Ri.ks from natural hazards i. urban areas call for the establi.hment of ri.orous and parti.i.atory urban ri.k governance. i. thi. study, we exami.ed parti.i.atory ri.k governance(PRG) of flood ri.k management(FRM) i. Seoul, South Korea. We conducted key i.formant i.tervi.ws and i.plemented a survey wi.h ci.i.ens, to explore percepti.ns of flood ri.ks and ri.k management, and to exami.e prospects for i.provi.g PRG i. Seoul. We found a gap between the percepti.ns of key i.formants and *** i.formants beli.ved that ci.i.ens' low awareness of flood ri.ks hi.ders PRG. Yet our research found that ci.i.ens' ri.k awareness was not low, and ri.k awareness may not be the mai. barri.r to parti.i.ati.n i. PRG. i.stead, we found that ci.i.ens lacked knowledge of FRM acti.ns, and they assi.ned government bodi.s a hi.h level of responsi.i.i.y for FRM,compared to the level of responsi.i.i.y that ci.i.ens assi.ned to themselves. Moreover, the actors i.volved i. FRM tended not to trust each other, whi.h i.pli.s a lack of mutual understandi.g. To i.crease the eff ecti.eness of PRG, we suggest a polycentri. governance structure anchored by a leadi.g actor group, and acti.e promoti.n of the parti.i.ati.n of actors at multi.le levels of governance. Communi.ati.n between government and ci.i.en parti.i.ants, desi.ned to foster i.proved understandi.g and recogni.i.n of one another's roles and contri.uti.ns to FRM, wi.l enhance trust and i.prove the i.plementati.n of PRG i. Seoul.

作者： garca-ro i. Pérez-Gala S. Aragüés M. 周少娜 Dermatology Department Hospital de La Princesa Diego de León 62 28006 Madrid Spain

Background: Sweet’s syndrome (SS) has been reported i. associ.ti.n wi.h many condi.i.ns, i.cludi.g mali.nancy, i.fecti.ns, autoi.mune di.orders, pregnancy and drugs. Materi.ls and methods: We revi.wed pati.nts wi.h SS-li.e lesi.ns on the lymphoedema area seen i. our department. Cli.i.al mani.estati.ns, hi.topathologi. characteri.ti.s, treatment and outcome data were recorded and analysed. Results: We report seven women wi.h a hi.tory of surgery for breast cancer wi.h axi.lary lymphadenectomy. Si. of them were on tamoxi.en. All of them had vari.us lesi.ns consi.tent wi.h SS locali.ed predomi.antly on the li.b affected by the postmastectomy lymphoedema, and on the i.si.ateral chest, trunk and back. One of them presented bullous lesi.ns. Three of the cases underwent spontaneous remi.si.n, two resolved wi.h anti.i.ti. therapy, one healed wi.h corti.osteroi.s, and one wi.h corti.osteroi.s plus anti.i.ti.. Conclusi.ns: Erythematous tender plaques on the area of postmastectomy lymphoedema could be consi.ered an unusual mani.estati.n of Sweet’s syndrome. We have found only three si.i.ar cases i. the li.erature. Although i. i. di.fi.ult to eluci.ate the pathogenesi. of thi. enti.y, i. has been suggested that i. could be due to i.mune survei.lance i.pai.ment.

The paper presents the change i. grai.-si.e composi.i.n of li.ni.e under cycli. freezi.g-thawi.g (FTC) and wetti.g-dryi.g (WDC). The arti.le shows that i. the spri.g and autumn peri.ds the li.ni.es can be subjected to repeated freezi.g-thawi.g and wetti.g-dryi.g, whi.h determi.es the possi.i.i.y of changi.g thei. grai.-si.e composi.i.n and structure. Experi.ental studi.s i. laboratory condi.i.ns on the i.fluence of cycli. freezi.g-thawi.g (FTC) and wetti.g-dryi.g (WDC) on the quali.y i.di.ators of li.ni.es have been carri.d out, thei. granulometri. (fracti.nal) composi.i.n has been studi.d. Freezi.g-thawi.g cycle condi.i.ns are as follows (FTC): mi.i.um exposure temperature: -20°C;maxi.um: +5°C;relati.e humi.i.y: 30%;number of processi.g cycles: 3. Wetti.g-dryi.g cycles are as follows (WDC): dryi.g temperatures are +20, +40, +60, +80°C, dryi.g ti.e 90 mi.utes, the coals are further subjected to rai. (soaki.g) for a peri.d of water saturati.n to humi.i.y of 30% - 40% and dry agai.. The number of wetti.g-dryi.g cycles i. 3 ti.es. The tests have revealed the destructi.e effects of FTC and WDC on the samples of lower metamorphi. grade coal, and the cycles of wet-dry lead to the much hi.her yi.ld of fi.e si.es (-6+0;-13+0 mm) than the cycles of freeze-thaw. Furthermore, i. i. found that the i.crease i. the yi.ld of fi.es depends on the heati.g temperature: coal di.i.tegrati.n proceeds more i.tensi.ely at a hi.her temperature of dryi.g.

A Di.ensi.nal Reducti.n Approach Based on Essenti.l Constrai.ts i. Li.ear Programmi.g

引用

Ameri.an Journal of Operati.ns Research 2024年第1期14卷 1-31页

作者： Ei.i.i.i. Ni.olopoulou George S. Androulaki. Department of Mathemati.s University of Patras Patras Greece Department of Busi.ess Admi.i.trati.n University of Patras Patras Greece

Thi. paper presents a new di.ensi.n reducti.n strategy for medi.m and large-scale li.ear programmi.g problems. The proposed method uses a subset of the ori.i.al constrai.ts and combi.es two algori.hms: the wei.hted average and the cosi.e si.plex algori.hm. The fi.st approach i.enti.i.s bi.di.g constrai.ts by usi.g the wei.hted average of each constrai.t, whereas the second algori.hm i. based on the cosi.e si.i.ari.y between the vector of the objecti.e functi.n and the constrai.ts. These two approaches are complementary, and when used together, they locate the essenti.l subset of i.i.i.l constrai.ts requi.ed for solvi.g medi.m and large-scale li.ear programmi.g problems. After reduci.g the di.ensi.n of the li.ear programmi.g problem usi.g the subset of the essenti.l constrai.ts, the soluti.n method can be chosen from any sui.able method for li.ear programmi.g. The proposed approach was appli.d to a set of well-known benchmarks as well as more than 2000 random medi.m and large-scale li.ear programmi.g problems. The results are promi.i.g, i.di.ati.g that the new approach contri.utes to the reducti.n of both the si.e of the problems and the total number of i.erati.ns requi.ed. A tree-based classi.i.ati.n model also confi.med the need for combi.i.g the two approaches. A detai.ed numeri.al example, the general numeri.al results, and the stati.ti.al analysi. for the deci.i.n tree procedure are presented.

The electroni. properti.s of several prospecti.e nuclear fuels are not yet well known. We used Quantum Espresso and EPW codes to evaluate the electron densi.y of states, the electroni. heat capaci.y coeffi.i.nt, the electron-phonon coupli.g strength, the number of mobi.i.y electrons, and the electroni. heat conducti.i.y. The electroni. properti.s for ThN, ThC and UN usi.g a sli.htly di.ferent approach that were previ.usly evaluated are di.cussed and the results are compared. We confi.med that whi.e the electroni. heat capaci.y coeffi.i.nt i. li.early dependent on the electron densi.y of states at Fermi.energy, such a si.ple relati.n could not be used to determi.e the di.ference i. the electroni. heat conducti.i.y of i.vesti.ated materi.ls. The hi.hest heat conducti.i.y was regi.tered i. ThN. These metalli. fuels also have hi.h U/Th densi.y, therefore are more economi.al si.ce enri.hment i. expensi.e. Furthermore, i. i. i.portant to exami.e swelli.g i. these hi.h-densi.y fuels. We evaluated that UN had 42% more U atoms per uni. volume than UO2 and a 55% hi.her volume i.crease when accommodati.g one Xe atom i. one i.tersti.i.l of a (2 × 2 × 2) supercell. However, for He, the volume i.crease was 27% lower i. UN. i.teresti.gly, even though the Th atom’s densi.y i. ThN and ThC was lower than that of U atoms i. the UN compound, a si.i.ar trend of volume changes was found. We concluded, therefore, that when we consi.er swelli.g, the local structural symmetry (tetrahedral versus octahedral si.es) i. more i.portant than the densi.y of atoms. The 37 % greater of absolute value of the total energy i.crease due to i.corporati.n of Xe i. ThC versus ThN cannot be explai.ed by the crystal structure si.ce a ThC-Xe supercell has a hi.her latti.e constant than a ThN-Xe correspondi.g supercell. Such results can only be explai.ed by i.vesti.ati.g electroni. structure.
