A superconduct.ng coil syst.m is act.ally complicat.d by t.e dist.ibut.d paramet.rs, e.g. t.e dist.ibut.d mut.al induct.nce among t.rns and t.e dist.ibut.d capacit.nce bet.een adjacent.conduct.rs. In t.is paper, such a complicat.d syst.m was modeled wit. a reasonably simplified circuit.net.ork wit. lumped paramet.rs. t.en, a det.iled circuit.analysis was conduct.d t. evaluat. t.e possible volt.ge t.ansient.in t.e coil circuit. As a result. an appropriat. （minimum） snubber capacit.nce for t.e Swit.hing Net.ork Unit. which is a fast.high volt.ge generat.on circuit.in Jt.60SA, was obt.ined.

Low act.vat.on mat.rials have t. be developed t.ward fusion demonst.at.onreact.rs. Ferrit.c st.el, vanadium alloy and SiC/SiC composit. are candidat. mat.rials of t.e first.all, vacuum vessel and blanket.component., respect.vely. Alt.ough changes of mechanical-t.ermalpropert.es owing t. neut.on irradiat.on have been invest.gat.d so far, t.ere is lit.le dat. for t.eplasma mat.rial int.ract.ons, such as fuel hydrogen ret.nt.on and erosion. In t.e present.st.dy,deut.rium ret.nt.on and physical sput.ering of low act.vat.on ferrit.c st.el, F82H, wereinvest.gat.d by using deut.rium ion irradiat.on apparat.s. Aft.r a ferrit.c st.el sample wasirradiat.d by 1.7 keV D^+ ions, t.e weight.loss was measured t. obt.in t.e physical sput.eringyield. t.e sput.ering yield was 0.04, comparable t. t.at.of st.inless st.el. In order t. obt.in t.eret.ined amount.of deut.rium, t.chnique of t.ermal desorpt.on spect.oscopy (t.S) was employed t. t.eirradiat.d sample. t.e ret.ined deut.rium desorbed at.t.mperat.re ranging from 450 k t. 700 k, int.e forms of DHO, D_2, D_2O and hydrocarbons. Hence, t.e deut.rium ret.ined can be reduced by bakingwit. a relat.vely low t.mperat.re. t.e fluence dependence of ret.ined amount.of deut.rium wasmeasured by changing t.e ion fluence. In t.e ferrit.c st.el wit.out.mechanical polish, t.e ret.inedamount.was large even when t.e fluence was low. In such a case, a large amount.of deut.rium wast.apped in t.e surface oxide layer cont.ining O and C. When t.e fluence was large, t.e t.ickness ofsurface oxide layer was reduced by t.e ion sput.ering, and t.en t.e ret.ined amount.in t.e oxidelayer decreased.

Many kinds of feed addit.ves （e.g., probiot.cs, prebiot.cs, ant.biot.cs, et..） can be used in chicken diet. t. st.mulat. int.st.nal morphological mat.rat.on and, consequent.y, int.st.nal funct.on. t.e aim of t.is t.ial was t. invest.gat. t.e possibilit. t.at.nat.ral zeolit. including plant.ext.act.（ZEM） could encourage t.e hypert.ophy of int.st.nal villi and t.e absorpt.ve funct.on of epit.elial cells in broiler chickens. At.7 days old, 64 male Marshall Chunky broilers were divided int. four groups, each wit. four replicat.s of four chickens. t.e birds were fed a basal mash diet.supplement.d wit. ZEM at.0% （cont.ol）, 0.05%, 0.1%, and 0.2% for 42 days. At.49 days old, four chickens from each t.eat.ent.were killed t. obt.in int.st.nal samples. Morphological int.st.nal assessment.was conduct.d using bot. a light.and a scanning elect.on microscope. A t.ndency t. increased villus height.and cell area could be observed t.roughout.t.e int.st.nal segment. of t.e broilers fed ZEM. Part.cularly, t.e villus height.in t.e duodenum was significant.y increased （P 〈 0.05） in t.e 0.05% ZEM group when compared wit. t.e cont.ol group. t.e area of t.e villus cells t.nded t. be higher in t.e ZEM groups in all int.st.nal regions and showed a significant.increase （P 〈 0.05） in t.e ileal part.of t.e 0.2% ZEM group. Also, t.e assessment.of cells mit.sis in t.e int.st.nal crypt. showed significant.y higher numbers （P 〈 0.05） in all levels of ZEM groups in t.e duodenum and a t.ndency t. increase in value in t.e jejunum and ileum, as compared wit. t.e cont.ol group. More prot.berat.d cells and mult.-cell clust.rs were found in t.e ZEM groups t.an in t.e cont.ol group, result.ng in a rough cellular surface. In conclusion, t.e present.st.dy might.suggest.t.at.t.e int.st.nal villi and epit.elial cells on t.e villus apical surface are hypert.ophied in t.e ZEM groups, and t.at.int.st.nal villi adapt.t. enhance t.eir absorpt.on capacit. by increasing t.e absorpt.ve surface area. t.ese result. are i

t.e phenc, lic compounds found in mango fruit.are ant.oxidant., and cont.ibut. t. a reduct.on in t.e risk of cardiovascular diseases. Mango carot.noids are synt.esized in mango fruit.during ripening. A major by-product.of mango fruit.is t.e skin, which is available aft.r t.e fruit. is consumed or used, part.cularly in t.e preparat.on of jams and fruit.juices by t.e fruit.canning indust.y. t.e object.ve of t.is st.dy was t. invest.gat. t.e effect. of diet.ry mango skin （MS） or mango skin combined wit. paprika ext.act. （PE） on product.on performance, egg qualit., and egg yolk polyphenols. t.t.l of 60 44-week-old Boris Brown hens was assigned, based on egg product.on rat. and body weight. t. 6 groups （10 birds in each group）. t.e laying hens were fed a basal diet.（cont.ol group, 18 CP, 2,800 kcal/kg ME）, a basal diet.supplement.d wit. 0.1% PE, 1% or 5% MS, or wit. a mixt.re of 0.1% PE wit. 1% or 5% MS respect.vely. During t.e t.ree-week experiment.l feeding period, t.e birds had free access t. feed and wat.r. Feed consumpt.on was measured weekly and egg product.on was recorded daily. t.e result. for init.al body weight. feed consumpt.on, hen-day product.on, egg mass, mort.lit., and final body weight.did not.indicat. any effect. of t.e different.t.eat.ent. （P 〉 0.05）. t.ere were no significant.differences （P 〉 0.05） in shell-breaking st.engt., shell t.ickness, shell rat.o, yolk rat.o or Haugh unit., except.in t.e case of egg yolk color.

In int.rnat.onal t.ermonuclear experiment.l react.r （It.R）, one of major concerns is an in-vessel t.it.um invent.ry from a point.of safet.. It.is believed t.at.t.e carbon-t.it.um co-deposit.d film produced by t.e erosion of carbon divert.r walls has a high t.it.um concent.at.on. However, no syst.mat.c evaluat.on for t.e t.it.um concent.at.on has been conduct.d yet. In t.e present.st.dy, t.e carbon-hydrogen co-deposit.d films were prepared at.t.e wall of pumping duct.in Local Island Divert.r experiment. of LHD, in order t. evaluat. t.e t.it.um concent.at.on of t.e co-deposit.d films produced in It.R. t.e hydrogen concent.at.on was obt.ined by measuring t.e amount.of ret.ined hydrogen in t.e film and t.e mass densit. of t.e film. t.e hydrogen concent.at.on of t.e co-deposit.d carbon film at.t.e wall not.facing t. t.e plasma wit. a low t.mperat.re was ext.emely high, 1.3 in t.e at.mic rat.o of H/C. t.is value is t.iple t.mes higher t.an t.e previous value obt.ined so far. t.e cryst.l st.uct.re of t.e co-deposit.d carbon film observed by Raman spect.oscopy showed very unique st.uct.re （polymeric aC：H）, which is well consist.nt.wit. t.e high hydrogen concent.at.on. t.e present.st.dy suggest. t.at.t.e t.it.um concent.at.on of t.e co-deposit.d film in It.R depends on t.e wall posit.on and becomes quit. high as high as t.C-0.65. t.e result. obt.ined cont.ibut. t. evaluat. t.e in-vessel t.it.um invent.ry owing t. t.e co-deposit.d carbon films.
