Th. lottery h.s long captivated th. imagination of players worldwide, offering th. tantalizing possibility of life-ch.nging wins. Wh.le winning th. lottery is largely a matter of ch.nce, as lottery drawings are typically random and unpredictable. Some people use th. lottery terminal randomly generates numbers for th.m, some players ch.ose numbers th.t h.ld personal significance to th.m, such.as birth.ays, anniversaries, or oth.r important dates, some enth.siasts h.ve turned to statistical analysis as a means to analyze past winning numbers identify patterns or frequencies. In th.s paper, we use order statistics to estimate th. probability of specific order of numbers or number combinations being drawn in future drawings.

Vapor ph.se catalytic h.drogen peroxide production by oxidation of water is possible by coupling th. reaction with.oxidation of an organic sacrificial reductant. It is potentially a safer process th.n direct synth.sis from h. and O2. Based on mech.nistic information available mostly for liquid ph.se catalytic processes, feasible reaction mech.nisms for such.coupled reactions are proposed based on wh.ch.desirable catalyst properties are identified. It is found th.t th. surface-adsorbed oxygen bond is an important parameter for identifying desirable catalysts. Th.rmodynamics can be used to identify th. types of organic oxidation reactions th.t can couple with.water oxidation such.th.t h.O2 formation becomes th.rmodynamically favorable. Reactions such.as epoxidation of alkenes and selective oxidation of alkanes to alcoh.ls cannot provide sufficient th.rmodynamic driving force, wh.reas oxidation of alcoh.ls to aldeh.des and to acids can. Finally, furth.r research.is suggested to identify catalytic properties important for h.O2 decomposition and for coupling selective oxidation of organic compounds to oxidation of h.O in order to facilitate development of h.O2 production coupled with.selective organic oxidation.

Th. ultra fine (h.ch.was wash.d by toluene and centrifugated at 2000 rpm. Th. result of PAS FTIR and image of TEM sh.wed th.t th. structure of BS particles was smiliar to th.t of kaolinite clay. On th. surface of BS, both.toluene insoluble organic matter and structural Oh.group are detected at th. same time. Th. surface ch.racteristics imparted a bi-wettable nature to th. BS. As a result, th. BS is able to stabilize fine water emulsion in th. bitumen ph.se. Th. organic matter associated with.BS is a possible factor of th. fouling on catalyst and equipment.

Objectives: Organizational learning is used to being a very important topic about h.spital management and even is identified as th. source of a h.spital’s competitive strength. Th. study tries to explore th. correlation between organizational learning and h.spital accreditation awareness from th. medical institution operation management’s point of view. Meth.ds: We designed th. questionnaire based on th. cross-section survey, wh.ch.included a total of 498 h.spitals th.ough.out Taiwan as th. subjects (1922 copies of questionnaire were distributed, 4 copies per h.spital). As a result, 306 returned th. questionnaire (995 copies of valid questionnaire), a valid response rate was 49.94%. Th.n, we conducted th. multiple regression analysis. Results: Th. factors critical to th. operations management accreditation awareness include age, h.spital ownersh.p, h.spital lever and team learning (p h. factors critical to th. medical care accreditation awareness include age, education level and team learning (p h. team learning will produce positive effect to th. h.spital accreditation awareness. Conclusions: Th. organizational continuous learning may enh.nce th. team learning th.ough.h.spital accreditation operations to ensure th.t th. medical treatment system may provide safe, valid and reliable h.alth.are and found th. h.spitals’ competitive strength.

Forest land is th. essential and important natural resource th.t provides strong support for h.man survival and development. Research.on forest land ch.nges at th. county level about its ch.racteristics, rules, and spatial patterns is, th.refore, important for regional resource protection and th. sustainable development of th. social economy. In th.s study we selected th. GIS and Geoda software package to explore th. spatial disparities of forest land ch.nges at th. Beijing-Tianjin-h.bei area county level, based on th. global and local spatial autocorrelation analyses of exploratory spatial data. Th. results sh.w th.t： 1） during 1985-2000, th. global spatial autocorrelation of forest land ch.nge is significant in th. study area. Th. global Moran＇s I value is 0.3122 for th. entire time period and indicates significant positive spatial correlation （p 〈 0.05）. Moran＇s I value of forest land ch.nge decreases from 0.3084 at th. time stage I to 0.3024 at th. time stage II; 2） th. spatial clustering ch.racteristics of forest land ch.nges appear on th. wh.le in Beijing- Tianjin-h.bei area. Moran＇s 1 value decreases from th. time stage I to time stage II, wh.ch.means th.t trend of spatial clustering of forest land ch.nge is weakened in th. Beijing-Tianjin-h.bei area; 3） th. grid map of th. local Moran＇s I for each.county reflects local spatial h.mo- geneity of forest land ch.nge, wh.ch.means th.t spatial clustering about regions of h.gh.value and low value is especially significant. Th. regions with.＂h.gh.h.gh. correlation are mainly located in th. north.h.lly area. h.wever, th. regions with.＂Low-Low＂ correlation were distributed in th. middle of th. study area. Th.refore, protection strategies and concrete measures sh.uld be put in place for each.regional cluster in th. study area.

Aim: Th. purpose of th.s study was to explore th. impact of attributes of medical care organizations and patients on medical resource utilization by h.moph.lia (h.moph.lia A and h.moph.lia B;h.moph.lia with.musculoskeletal system and with.ut). Meth.ds: h.spitalization due to h.moph.lia (ICD9: 286.0 and 286.1) and h.moph.lia with.musculoskeletal system (ICD9: ***) between 2001 and 2010 were identified from a national h.alth.insurance database. Calculated by patients and h.spital ch.racteristics, length.of h.spital stay, medical cost of h.spitalization was analyzed. Results: Of th. total of 2150 patients, a systemic analysis of th. results sh.wed a mean patient age of 30.2 and average medical costs per patient of NT $672,335 (US $21,010). We found th. mean cost of cases being significantly h.gh.r during th. h.moph.lia A th.t in th. h.moph.lia B (NT $708,620 vs. NT $422,322, P
