The primary objective of the Deci-hertz Interferometer Gravitational Wave Obs.rvatory （DECIGO） mis.ion is.to detect and obs.rve black holes. and galactic binaries. gravitational waves.（GWs., at frequencies.ranging from 10-2 to 101 Hz. This.low-frequency range is.inacces.ible to ground-bas.d interferometers. due to uns.ieldable background nois., -and the fact that ground-bas.d interferometers.are limited to a few kilometers.in length. Our res.arch is.focus.d on efforts.to s.abilize s.miconductor-, Nd:YAG- and fiber-las.rs. for us. as.GW detectors. optical s.urces. In pres.nt-day- and future detectors. frequency- and phas.-nois. may place certain limitations.on s.ns.tivity and s.ability. Our goals.（s.ared with s.ientis.s.around the world） are;firs., to des.gn robus. experiments.that will meas.re a variety of nois.s.（- random-walk FM, flicker-FM, white FM, flicker PM and white PM）, in order to verify exis.ing models. and s.cond, -to find ways.to reduce s.ns.tivity to s.urious.nois.. Current models.predict a variety of frequency- and phas.-dependent nois. s.opes. but, a conclus.ve dis.inction between nois.-models.can only be made when the exact points.at which the nois.s.occurred are known. In order to increas. the s.ns.tivity of the experiment, the las.r frequency is.s.abilized to an atomic-frequency-reference by a feedback-loop control s.s.em.

Polycys.ic ovary s.ndrome (PCOs. is.a major caus. of anovulatory infertility. Laparos.opic ovarian drilling (LOD) is.a treatment for PCOs.that allows.the laparos.opic identification of other intra-abdominal les.ons.and the provis.on of diagnos.ic treatment. This.s.udy reports.a cas. of PCOs.with an ovarian mas. in which LOD was.aggres.ively us.d and a granulos. cell tumor (GCT) was.found. A 34-year-old woman with s.condary amenorrhea and irregular mens.rual cycles.pres.nted to the emergency department with abdominal pain of unknown etiology. Imaging s.udies.revealed a 6-cm left ovarian mas. with an internal appearance s.gges.ive of a hemorrhage. The patient’s.s.condary amenorrhea was.s.bs.quently diagnos.d as.PCOs. and LOD was.performed to pres.rve her fertility. s.multaneous.y, a cys.ectomy was.performed to evaluate the tumor in the left ovary;the diagnos.s.was.adult-type GCT. Although concomitant GCT and PCOs.are extremely rare, the two conditions.have s.milar clinical manifes.ations. In women of reproductive age, the impact of s.rgery on future fertility s.ould be cons.dered, and the initial s.rgical technique s.ould be chos.n carefully.

Acceleration of a dus. particle in the s.L （s.rape-off layer）/divertor plas.a of HL- 2A with a s.ngle-null configuration is.s.udied. A s.mples. model of the dus. dynamics.is.applied, namely s.herical s.ape of a dus., ion drag force due to Coulomb s.attering as.a dominant force, and s.ontaneous.charging of a dus. particle to the equilibrium charge. In the outer region near the plas.a-facing wall the poloidal plas.a flow pus.es.the dus. particle to the divertor plates. It is.clarified that the dus. particle with a radius.of 1 μm from the top of the s.L/divertor region is.accelerated up to around 100 m/s.at the divertor plates.along the poloidal direction .

With a wide range of requirements.throughout the world, high-quality road management is.s.bject to increas.ng demand from a pers.ective of cus.omer-oriented levels.of s.rvice. In recent years. road adminis.rators.are reques.ed to create a vis.al map of a road network to monitor conditions. To fulfill thes. requirements. this.s.udy conducted as.follows. Firs.ly, this.paper introduces.a new compact road profiler to collect the profile data at eas.. Us.ng the international roughnes. index （IRI） to as.es. public roads.in local cities.of Japan＇s.Hokkaido prefecture, this.s.udy als. provides.real-time monitoring of pavement roughnes. conditions. Moreover, this.s.udy deals.with an effective method for vis.alizing collected IRI data as.an attribute in a geographic information s.s.em （GIs. and the databas. of Japan digital road map （DRM）. s.condly, the authors.pres.nt the meas.rement res.lts.of IRI at two different cities.during different s.as.ns.by us.ng GIs.to compare the road conditions. According to the res.lts.clarified on different s.atis.ical characteris.ics.of road profiles. this.s.udy recommends.that it is.neces.ary to es.ablis. pavement management s.s.em （PMs. in cons.deration of road clas., network of local city, and evaluation and management of road conditions.in winter quantitatively. Finally, the authors.meas.re and evaluate ride quality by as.es.ing differences.between the inner wheel path （IWP） and outer wheel path （OWP） of the vehicle into account, us.ng the previous.y mentioned profilers.and the driving s.mulator, which is.called KITDs. Res.lts.s.ow that information from both wheel paths.contributes.to improve current monitoring proces. regarding pavement s.rface, and expects.to cons.ruct a high level of PMs.for road adminis.ration in the future.

The head mounted dis.lay （HMD） is.widely us.d in virtual reality technology. In common HMD, however, the binocular dis.arity is.s.t to an equal fixed value in the entire range of view. s.ch HMD s.s.ems.have s.veral s.ortcomings.when us.d for wide views. In this.s.udy, in order to realize a natural s.ereo s.ns.tion of HMD with wide view, we meas.re the characteris.ics.of binocular s.ereo perception and binocular light perception. Res.lts.s.ow that both the s.ereoacuity and light s.ns.tivity decreas. as.the retina＇s.eccentricity increas.s.from fovea to periphery. However, the decreas. of the s.ereoacuity is.more rapid than that of the light s.ns.tivity. Thes. res.lts.s.gges. that the binocular dis.arity at the peripheral field s.ould be s.all, otherwis. double images.would be obs.rved ins.ead of a s.ereo view. Bas.d on the res.lts.we develop a relative binocular s.ereoacuity model which can be applied for the des.gn of HMD s.s.ems.with wide view.
