Effect of Animacy on Word Order Processing in Kaqchikel Maya  [PDF]
Sachiko Kiyama, Katsuo Tamaoka, Jungho Kim, Masatoshi Koizumi
Open Journal of Modern Linguistics (OJML) , 2013, DOI: 10.4236/ojml.2013.33027

This study investigated the processing load of transitive sentences in two different basic word orders (i.e., VOS and SVO) in Kaqchikel Maya, with a particular focus on the animacy of the object. The results of a sentence plausibility judgment task showed that VOS sentences were processed faster than SVO sentences regardless of the animacy of the object. This supports the traditional analysis in Mayan linguistics that, although SVO is the most frequently used word order, the syntactically determined basic word order is VOS in Kaqchikel, as in many other Mayan languages. More importantly, the results suggest that the processing load in Kaqchikel sentence comprehension is more strongly affected by syntactic canonicity than production frequency or object animacy.

Charge-transfer and Mott-Hubbard Excitations in FeBO3: Fe K edge Resonant Inelastic X-ray Scattering Study
Jungho Kim,Yuri Shvyd'ko
Physics , 2010, DOI: 10.1103/PhysRevB.83.235109
Abstract: Momentum-resolved resonant inelastic x-ray scattering (RIXS) spectroscopy has been carried out at the Fe K edge, successfully for the first time. The RIXS spectra of a FeBO3 single crystal reveal a wealth of information on 1-10 eV electronic excitations. The IXS signal resonates both when the incident photon energy approaches the pre-edge (1s-3d) and the main-edge (1s-4p) of the Fe K edge absorption spectrum. The RIXS spectra measured at the pre-edge and the main-edge show quantitatively different dependences on the incident photon energy, momentum transfer, polarization, and temperature. Electronic excitations observed in the pre-edge and main-edge RIXS spectra are interpreted as Mott-Hubbard (MH) and charge-transfer (CT) excitations, respectively. The charge-transfer gap = 3.81 (0.04) eV and the Mott-Hubbard gap = 3.96 (0.04) eV, are determined, model independently from the experimental data. The CT and MH excitations are assigned using molecular orbitals (MO) in the cluster model and multiplet calculation in the many-electron multiband model, respectively.
Enhancement of Toxic Gas Detecting Ability of Film Type Colorimetric Sensor  [PDF]
Sung Yeol Kim, Seung Kyun Yoon, Jungho Ahn, Dong June Chung
Journal of Materials Science and Chemical Engineering (MSCE) , 2016, DOI: 10.4236/msce.2016.41008

In this study, we tried to develop the in situ coating methods of hydrophilic polymer solution containing water soluble dye on nonwoven sheet for the colorimetric film sensor. And color change of coated dye according to contact various gas samples (as strong acid and base, chloroform, ammonia and HF) of this dye-coated nonwoven film was examined for the application of chemically toxic materials detecting tools in the actual site of working place without aid of any kinds of detecting devices. By the addition of electron transfer agent (quinone derivatives), quick color change behaviors were observed within 10 seconds under the contact of various toxic gases in general condition(room temperature, 50% humidity).

Does fertility decrease household consumption?: An analysis of poverty dynamics and fertility in Indonesia
Jungho Kim,Henriette Engelhardt,Alexia Prskawetz,Arnstein Aassve
Demographic Research , 2009,
Abstract: This paper presents an empirical analysis of the relationship between fertility and a direct measure of poverty for Indonesia, a country, which has experienced unprecedented economic growth and sharp fertility declines over recent decades. It focuses on illustrating the sensitivity of the effect of fertility on household consumption with respect to the equivalence scale by applying the propensity score matching method. The analysis suggests that a newborn child decreases household consumption per person by 20 percent within four years. When the estimates of equivalence scales implied by the Indonesian sample are applied, the effect of a child on household consumption is still negative, but the magnitudes are in the range from 20 to 65 percent of that found with the per-capita expenditure as a measure of consumption. Therefore, it is suggested that the analysis based on the conventional measure of poverty is likely to exaggerate the effect of fertility on poverty at least because of the neglect of the proper equivalence scale.
Hard X-ray Spectrographs with Resolution Beyond 100 micro-eV
Yuri Shvyd'ko,Stanislav Stoupin,Kiran Mundboth,Jungho Kim
Physics , 2012, DOI: 10.1103/PhysRevA.87.043835
Abstract: Spectrographs take snapshots of photon spectra with array detectors by dispersing photons of different energies into distinct directions and spacial locations. Spectrographs require optics with a large angular dispersion rate as the key component. In visible light optics diffraction gratings are used for this purpose. In the hard x-ray regime, achieving large dispersion rates is a challenge. Here we show that multi-crystal, multi-Bragg-reflection arrangements feature cumulative angular dispersion rates almost two orders of magnitude larger than those attainable with a single Bragg reflection. As a result, the multi-crystal arrangements become potential dispersing elements of hard x-ray spectrographs. The hard x-ray spectrograph principles are demonstrated by imaging a spectrum of photons with a record high resolution of $\Delta E \simeq 90 \mu$eV in hard x-ray regime, using multi-crystal optics as dispersing element. The spectrographs can boost research using inelastic ultra-high-resolution x-ray spectroscopies with synchrotrons and seeded XFELs.
Pilot Signal Design for Massive MIMO Systems: A Received Signal-To-Noise-Ratio-Based Approach
Jungho So,Donggun Kim,Yuni Lee,Youngchul Sung
Mathematics , 2014, DOI: 10.1109/LSP.2014.2364180
Abstract: In this paper, the pilot signal design for massive MIMO systems to maximize the training-based received signal-to-noise ratio (SNR) is considered under two channel models: block Gauss-Markov and block independent and identically distributed (i.i.d.) channel models. First, it is shown that under the block Gauss-Markov channel model, the optimal pilot design problem reduces to a semi-definite programming (SDP) problem, which can be solved numerically by a standard convex optimization tool. Second, under the block i.i.d. channel model, an optimal solution is obtained in closed form. Numerical results show that the proposed method yields noticeably better performance than other existing pilot design methods in terms of received SNR.
En bloc Extended Total Thymectomy and Extrapleural Pneumonectomy in Masaoka stage IVA Thymomas
Hee Yang, Yoo Yoon, Hong Kim, Yong Choi, Kwhanmien Kim, Young Shim, Jungho Han, Jhingook Kim
Journal of Cardiothoracic Surgery , 2011, DOI: 10.1186/1749-8090-6-28
Abstract: From 1994 to 2009, five patients initially diagnosed with pleural dissemination and two patients with recurrent tumors in the pleura and lungs after a total thymectomy, were identified. Seven patients had an extrapleural pneumonectomy performed. For the first operation, five patients underwent additional en bloc extended total thymectomy.Two recurrent cases were identified 55.2 and 12.3 months after first operation. Two patients had WHO type B1-B2 tumors, two had B2, two had B2-B3, and one had a B3 tumor. The mean hospital stay was 15.3 days (range: 7-29). There was no operative mortality. Four patients had neoadjuvant chemotherapy and five were treated with adjuvant chemotherapy. The median survival was 30.6 months and the Kaplan-Meier 2-year survival was 100% (95% confidence interval: 24.6-36.6 months). One patient, who did not receive induction chemotherapy, had distant metastases after surgery.En bloc extended total thymectomy and extrapleural pneumonectomy can be safely performed on selected patients with stage IVA thymomas and is expected to achieve complete local control. Although the treatment strategy has yet to be standardized, complete resection with appropriate systemic therapy may improve survival in otherwise fatal disease.The prognosis of locally advanced thymomas within the thoracic cavity (Masaoka stage IVA) is poor [1-3]; there is no reliable treatment strategy established to date [4,5]. All three common therapeutic modalities (surgery, chemotherapy and radiation) can be used for the treatment of locally advanced thymoma [6,7]. However, the combination of these modalities has not been standardized.Complete local control is the mainstay of treatment for a thymoma; this is because thymomas rarely metastasize to distant organs. For stage IVA thymomas, the tumor has not yet spread to extrathoracic organs and is still locally advanced. This stage allows for complete eradication. However, in miliary or confluent pleural disseminated thymomas, complete re
Pixelation-free and real-time endoscopic imaging through a fiber bundle

Abstract: Endoscopy has been an indispensible tool in medical diagnostics, and yet the demands for reduced unit diameter and enhanced spatial resolution have steadily been growing for the accurate investigation of distal sites with minimal side effects. However, the attempts to make use of thin image-guiding media accompany the degradation in spatial resolution as the micro-optics often induces aberrations. Here, we present a microendoscope that performs real-time correction of severe aberrations induced by image-guiding media such as a bundled fiber. Specifically, we developed a method exploiting the full binary control of a digital micro-mirror device (DMD) for characterizing the input-output response of image-guiding media and subsequently compensating the aberrations. As a proof-of-concept study, we completely eliminated the pixelation artifact, a severe form of aberration, in endoscopic imaging through an image fiber bundle and achieved spatial resolution much better than the diameter of an individual fiber. Our study lays a foundation of applying extremely thin, but highly aberrant image-guiding media for high-resolution microendoscopy.
Reentrant spin glass transition in LuFe2O4
Fan Wang,Jungho Kim,G. D. Gu,Young-June Kim
Physics , 2007, DOI: 10.1103/PhysRevB.80.024419
Abstract: We have carried out a comprehensive investigation of magnetic properties of LuFe$_2$O$_4$, using AC susceptibility, DC magnetization and specific heat. A magnetic phase transition around $\sim$236 K was observed with DC magnetization and specific heat measurements, which is identified as a paramagnetic to ferrimagnetic transition based on the nonlinear susceptibility data. Upon further cooling below this temperature, we also observed highly relaxational magnetic behavior: the DC magnetization exhibits history and time dependence, and the real and imaginary part of the AC susceptibility shows large frequency dependence. Dynamic scaling of the AC susceptibility data suggests that this low temperature phase can be described as a reentrant spin glass phase. We also discuss magnetic field dependence of the spin glass transition and aging, memory and rejuvenation effect below the glass transition temperature around 228 K.
