This study in.estigates water vapor isotopic pattern. an. con.rols over Chin. usin. high-quality water vapor δD data retrieved from the Scan.in. Imagin. Absorption.Spectrometer for Atmospheric Chartography （SCIAMACHY） observation.. The results show that water vapor δD values on.both an.ual an. season.l time-scales broadly exhibit a con.in.n.al effect, with values largely decreasin. n.rthwestward from coastal lowlan.s to high-elevation.moun.ain.us region.. However, region.specific an.lysis reveals spatially distin.t pattern. of water vapor dD between.season.. In.the mon.oon.domain.（e.g., Chin. south of 35~n., depletion.in.D in.the summer an. fall season. is closely tied to mon.oon.moisture sources （the In.ian.an. Pacific ocean.） an. subsequen. amoun. effect, but higher 8D values in.win.er an. sprin. are a result of isotopically-en.iched con.i- n.n.al-sourced moisture proceeded by less rain.ut. In.con.rast, farther in.an. in.Chin. （n.n.mon.oon.domain., moisture is de- rived overwhelmin.ly from the dry con.in.n.al air masses an. local evaporation. an. 8D values are largely con.rolled by the temperature effect, exhibitin. a season.lity with isotopically en.iched summer an. depleted win.er/sprin.. The observation.that the spatial pattern.of water vapor δD is the opposite to that of precipitation.δD in.the summer season.also suggests that partial evaporation.of fallin. rain.rops is a key driver of water vapor isotope in.the n.n.mon.oon.domain.

In.estigation.of experimen.al con.iguration.for the electron.Bern.tein.wave （EBW） heatin. by usin. the existin. electron.cyclotron.heatin. （ECH） an.en.as on.LHD was performed.

Sin.e the parallel compon.n. of the refractive in.ex （n.F） varies durin. propagation.because of the in.omogen.ity of the magn.tic field, n. can.be zero when.the laun.hed X-mode crosses the fun.amen.al electron.cyclotron.reson.n.e （ECR） layer even.n. is n.on.ero in.tially. In.such a con.ition. if the electron.den.ity is above a certain.level the obliquely laun.hed X-mode can.pass the fun.amen.al ECR layer without bein. damped out an. can.be mode-con.erted to EBW that is absorbed at the Doppler shifted ECR layer. By usin. an.an.en.a in.talled in.the horizon.al port, oblique laun.hin. from the lower magn.tic field side （LFS） toward the over-den.e plasma is available. Excitation.of EBW via the mode con.ersion.process of ordin.ry mode（O）-extraordin.ry mode（X）-electron.Bern.tein.wave （B） is expected with the O-mode laun.hin. toward an.appropriate direction.

An.erior cin.ulated cortex (ACC) is in.olved in.“the state in.which patien.s do n.t care much about pain.despite its presen.e” which is a goal of psychosomatic treatmen.. To in.estigate the absolute con.en.ration.of n.acetylaspartate (n.A) in.the an.erior cin.ulated cortex (ACC) as predictors of patien.s that may ben.fit from cogn.tive behavioural therapy in.the treatmen. of chron.c pain. Proton.magn.tic reson.n.e spectroscopy (1H-MRS) was performed with a 1.5 T MR system on.a voxel in.the bilateral ACC in.85 chron.c pain.patien.s an. 20 age-matched n.rmal con.rol subjects. Eighteen.out of 24 (75.0%) patien.s whose n.A con.en.ration.decreased sign.fican.ly in.the ACC, respectively, compared to the mean.n.A con.en.ration.of the n.rmal con.rol subjects, n.eded cogn.tive behavioural therapy. Our results suggest that decreased n.A con.en.ration.in.the ACC is associated with the n.cessity of cogn.tive behavioural therapy. 1H-MRS may serve as a useful n.n.in.asive tool for evaluatin. chron.c pain.patien.s.

The con.ept of social capital en.ompasses all relation.hips an. n.tworks amon. people in.a local commun.ty or society as a whole. It has been.foun. to be associated with the health an. daily livin. status of people. Furthermore, an.association.between.social capital an. cogn.tive fun.tion. amon. the elderly has been.suggested in.recen. years. However, the n.mber of such reports is very few. Hen.e, the presen. study aims to evaluate the relation.hip between.social capital an. cogn.tive fun.tion. amon. the elderly livin. in.a local commun.ty in.Japan. A question.aire survey was admin.stered to 192 elderly in.ividuals belon.in. to 10 n.ighborhood elderly groups. A regression.an.lysis was con.ucted to determin. the relation.hip between.cogn.tive fun.tion. an. the level of en.agemen. with the local commun.ty, after adjustin. for age, gen.er, an. symptoms of depression. Valid respon.es were collected from 145 participan.s (mean.age: 75.3 years). An.an.lysis of the data con.ern.n. the level of en.agemen. with the local commun.ty revealed a sign.fican. differen.e in.the cogn.tive fun.tion.scores between.the group of people who in.icated that they had someon. they could con.ult (n.= 69) an. the group that in.icated they had n. on. to con.ult (n.= 76) (regression.coefficien.: -0.61, p = 0.0038, 95% con.iden.e in.erval: -1.02 to -0.20). This result in.icates the existen.e of a sign.fican. correlation.between.social capital an. cogn.tive fun.tion. of the elderly livin. in.a local commun.ty. In.future studies, we n.ed to in.estigate the same with a larger n.mber of participan.s from a wider geographical area, an. by in.orporatin. more in.icators for a comprehen.ive evaluation.of social capital.
