GAMBARAN PERAN IBU TERHADAP PERKEMBANGAN MOTORIK KASAR ANAK HIPOTIROID (STUDI KASUS DI KLINIK PENELITIAN DAN PENGEMBANGAN GAKI MAGELANG TAHUN 2015)
Salah satu manifestasi Gangguan Akibat Kekurangan Iodium pada anak adalah hipotiroid yang disertai gangguan perkembangan fisik dan mental. Salah satu manifestasi gangguan perkembangan tersebut adalah keterlambatan motorik kasar. Penelitian ini bertujuan mendeskripsikan peran ibu dalam melakukan stimulasi di rumah, terhadap perkembangan motorik kasar anak dengan riwayat hipotiroid di klinik penelitian dan pengembangan GAKI Magelang. Penelitian ini mengunakan pendekatan kualitatif eksploratif. Subyek penelitian adalah 9 ibu dari anak yang mengalami keterlambatan motorik kasar di sertai riwayat hipotiroid yang berkunjung di klinik litbang GAKI Magelang tahun 2010 – 2014. Data riwayat perkembangan motorik kasar anak diperoleh dari data sekunder, observasi dan wawancara ibu, serta pengukuran dengan Denver Development Screening Test II. Data pengetahuan ibu tentang perkembangan anak, sikap ibu menghadapi keterlambatan perkembangan anak, serta perilaku stimulasi ibu di rumah, diperoleh melalui wawancara dan observasi. Riwayat hipotiroid anak diperoleh dari data sekunder. Hasil penelitian ini menunjukan bahwa sebelum mendapat intervensi dari klinik litbang GAKI Magelang semua anak dalam penelitian ini belum mampu berjalan. Selama proses intervensi, semua anak menunjukan perbaikan kemampuan motorik kasar. Anak-anak yang ibunya tidak aktif melakukan stimulasi di rumah selama proses intervensi dari klinik Litbang GAKI Magelang, membutuhkan waktu lebih lama untuk perubahan satu tahap perkembangan motorik kasar dibandingkan anak yang ibunya secara aktif melakukan stimulasi saat dirumah. Jadi, dapat disimpulkan bahwa intervensi yang dilakukan secara lebih dini, disertai peran aktif ibu dalam memberikan stimulasi motorik kasar saat di rumah mampu meningkatkan efektifitas terapi. Hasil penelitian ini bisa menjadi bahan penyuluhan tentang pentingnya peran ibu terhadap perkembangan motorik kasar anak

Electric field gradients in MgB synthesized at high pressure: Cd TDPAC study and ab initio calculation
We report the high-pressure synthesis of novel superconductor MgB and
some related compounds. The superconducting transition temperature of our
samples of MgB is equal to 36.6 K. The MgB lattice parameters
determined via X-ray diffraction are in excellent agreement with results of our
ab initio calculations. The time-differential perturbed angular correlation
(TDPAC) experiments demonstrate a small increase in quadrupole frequency of
Cd probe with decreasing temperature from 293 to 4.2 K. The electric
field gradient (EFG) at the B site calculated from first principles is in fair
agreement with EFG obtained from B NMR spectra of MgB reported in the
literature. It is also very close to EFG found in our Cd TDPAC
measurements, which suggests that the Cd probe substitutes for boron in
the MgB lattice.Comment: 10 pages, 3 figure
Recent advances in neutrinoless double beta decay search
Even after the discovery of neutrino flavour oscillations, based on data from
atmospheric, solar, reactor, and accelerator experiments, many characteristics
of the neutrino remain unknown. Only the neutrino square-mass differences and
the mixing angle values have been estimated, while the value of each mass
eigenstate still hasn't. Its nature (massive Majorana or Dirac particle) is
still escaping. Neutrinoless double beta decay (-DBD) experimental
discovery could be the ultimate answer to some delicate questions of elementary
particle and nuclear physics. The Majorana description of neutrinos allows the
-DBD process, and consequently either a mass value could be measured or
the existence of physics beyond the standard should be confirmed without any
doubt. As expected, the -DBD measurement is a very difficult field of
application for experimentalists. In this paper, after a short summary of the
latest results in neutrino physics, the experimental status, the R&D projects,
and perspectives in -DBD sector are reviewed.Comment: 36 pages, 7 figures, To be publish in Czech Journal of Physic
Results of the BiPo-1 prototype for radiopurity measurements for the SuperNEMO double beta decay source foils
The development of BiPo detectors is dedicated to the measurement of
extremely high radiopurity in Tl and Bi for the SuperNEMO
double beta decay source foils. A modular prototype, called BiPo-1, with 0.8
of sensitive surface area, has been running in the Modane Underground
Laboratory since February, 2008. The goal of BiPo-1 is to measure the different
components of the background and in particular the surface radiopurity of the
plastic scintillators that make up the detector. The first phase of data
collection has been dedicated to the measurement of the radiopurity in
Tl. After more than one year of background measurement, a surface
activity of the scintillators of (Tl) 1.5
Bq/m is reported here. Given this level of background, a larger BiPo
detector having 12 m of active surface area, is able to qualify the
radiopurity of the SuperNEMO selenium double beta decay foils with the required
sensitivity of (Tl) 2 Bq/kg (90% C.L.) with a six
month measurement.Comment: 24 pages, submitted to N.I.M.
Spectral modeling of scintillator for the NEMO-3 and SuperNEMO detectors
We have constructed a GEANT4-based detailed software model of photon
transport in plastic scintillator blocks and have used it to study the NEMO-3
and SuperNEMO calorimeters employed in experiments designed to search for
neutrinoless double beta decay. We compare our simulations to measurements
using conversion electrons from a calibration source of and show
that the agreement is improved if wavelength-dependent properties of the
calorimeter are taken into account. In this article, we briefly describe our
modeling approach and results of our studies.Comment: 16 pages, 10 figure
Baikal-GVD
We present the status of the Gigaton Volume Detector in Lake Baikal (Baikal-GVD) designed for the detection of high energy neutrinos of astrophysical origin. The telescope consists of functionally independent clusters, sub-arrays of optical modules (OMs), which are connected to shore by individual electro-optical cables. During 2015 the GVD demonstration cluster, comprising 192 OMs, has been successfully operated in Lake Baikal. In 2016 this array was upgraded to baseline configuration of GVD cluster with 288 OMs arranged on eight vertical strings. Thus the instrumented water volume has been increased up to about 5.9 Mtons. The array was commissioned in early April 2016 and takes data since then. We describe the configuration and design of the 2016 array. Preliminary results obtained with data recorded in 2015 are also discussed
The Majorana Neutrinoless Double-Beta Decay Experiment
The proposed Majorana double-beta decay experiment is based on an array of
segmented intrinsic Ge detectors with a total mass of 500 kg of Ge isotopically
enriched to 86% in 76Ge. A discussion is given of background reduction by:
material selection, detector segmentation, pulse shape analysis, and
electro-formation of copper parts and granularity. Predictions of the
experimental sensitivity are given. For an experimental running time of 10
years over the construction and operation of Majorana, a half-life sensitivity
of ~4x10^27 y (neutrinoless) is predicted. This corresponds to an effective
Majorana mass of the electron neutrino of ~0.03-0.04 eV, according to recent
QRPA and RQRPA matrix element calculations.Comment: 10 pages, 7 figure
