Syntactic Differences of Plurality Markers

Joh,Yoon-kyoung 한국영미어문학회 2011 영미어문학 Vol.- No.98

There are two crucial syntactic differences found among plurality markers. Dependent plurals and anti-quantifiers work at the phrasal level as opposed to ordinary plurals that apply to the lexical level. More specifically, ordinary plurals are adjoined to the X level while anti-quantifiers attach to the full-fledged XP level. Dependent plurals, however, have the in-between status syntactically and combine with the X'-structure. Another difference is found between ordinary plurals and dependent plurals, on the one hand, and anti-quantifiers, on the other, in the respect that the former is a morpheme while the latter is a phrase that can take its own complement. These different statuses seem to account for why plural forms are intrinsically ambiguous whereas anti-quantifiers are unambiguously more expressive in their semantics as well as in their syntax than ordinary plurals and dependent plurals.

Adorning Materials in Middles

Yoon-kyoung Joh 서울대학교 언어교육원 2020 語學硏究 Vol.56 No.1

This paper claims that adorning materials in middles can commonly be translated into adverbials since modality, negation, and focus can all be expressed using various types of adverbials. Through the analytical lens that views middle constructions as distributivity constructions that are essentially reduced to plurality, this common property among adorning materials in middles is highly interesting. Thus, this paper accounts for the adorning materials in middles in Joh’s (2016) analysis, which treats adverbials in middles as one of distributivity’s core arguments. This paper also discusses how adverbials that are implicitly inserted in middle sentences can be conditioned. To answer this question, this paper relies on the differentiating effect that Sohn (2003) examined, extending the previously proposed unexpectedness condition.

Boiling performance and material robustness of modified surfaces with multi scale structures for fuel cladding development

Jo, H.,Kim, J.M.,Yeom, H.,Lee, G.C.,Park, H.S.,Kiyofumi, M.,Kim, M.H.,Sridharan, K.,Corradini, M. North-Holland Pub. Co 2015 Nuclear engineering and design Vol.291 No.-

By regulating the geometrical characteristics of multi-scale structures and by adopting heat treatment for protective layer of nanoparticles (NPs), we improved critical heat flux (CHF), boiling heat transfer (BHT), and mechanical robustness of the modified surface. We fabricated 1-mm and 100-μm post structures and deposited NPs on the structured surface as a nano-scale structured layer and protective layer at the same time, then evaluated the CHF and BHT and material robustness of the modified surfaces. On the structured surfaces without NPs, the surface with compactly-arranged micrometer posts had improved CHF (118%) and BHT (41%). On the surface with structures on which NPs had been deposited, CHF increased significantly (172%) due to capillary pumping by the deposited NP layers. The heat treatment improved robustness of coating layer in comparison to the one of before heat treatment. In particular, low-temperature sintering increased the hardness of the modified surface by 140%. The increased mechanical strength of the NP coating is attributed to reduction in coating porosity during sintering. The combination of micrometer posts structures and sintered NP coating can increase the safety, efficiency and reliability of advanced nuclear fuel cladding.

The spatial characteristics of bicycle-to-person collisions: a focus on bicycle paths of the Han River Park in Seoul, Korea

Jo H.,Shin E.,Kim H. 서울시립대학교 도시과학연구원 2020 도시과학국제저널 Vol.24 No.4

Recently, as the number of cyclists has grown in Seoul, Korea, bicycle traffic accidents have also increased rapidly. Most precedent research concerning bicycle traffic accidents has focused on the cases where motor vehicles have injured cyclists. Unlike preceding studies, this study focuses on the cases where bicycles have collided with pedestrians. The purpose of this study is to identify the spatial characteristics of the bicycle-to-person collisions caused by bicycles. Binomial Logistic Model is used to identify the spatial relationships of bicycle-to-pedestrian collisions. For the analysis, the entire Han River Park is broken down into 50  × 50 m grids, which become the units of analysis of this study. The target period for the analysis is set from 2014 to 2016. Dependent variables are accident points in the Han River Park. As the independent variables, the variety of spatial and physical factors of the Han River Park are considered. The model shows that the crosswalks, speed restriction features, street furniture, floating population, and bicycle rental shops in the Han River Park are significant factors relating to bicycle-to-pedestrian collisions.

Nonlinear optical (NLO) properties and temperature-dependent photoluminescence in activator-doped noncentrosymmetric (NCS) bismuth tellurite solid solutions, Bi_2-xLn_xTeO₅ (Ln = Ce and Eu)

Jo, H.,Yoo, J.S.,Ok, K.M. Elsevier Sequoia 2016 JOURNAL OF ALLOYS AND COMPOUNDS Vol.672 No.-

Activator-doped noncentrosymmetric (NCS) bismuth tellurite solid solutions, Bi<SUB>2-x</SUB>Ln<SUB>x</SUB>TeO<SUB>5</SUB> (Ln = Ce and Eu), have been successfully synthesized by solid state reactions. Crystal structure determination by powder X-ray diffraction using Rietveld method suggests that the solid solutions crystallize in the polar space group, Abm2 with pseudo-three-dimensional frameworks consisting of asymmetric polyhedra. Powder nonlinear optical (NLO) measurements, using 1064 nm radiation, reveal that the origin of large second-harmonic generation (SHG) efficiency of Bi<SUB>2-x</SUB>Ln<SUB>x</SUB>TeO<SUB>5</SUB> is the polarization arising from the alignment of lone pair cation, Bi<SUP>3+</SUP>. Photoluminescence (PL) intensity of Bi<SUB>1.9</SUB>Ce<SUB>0.1</SUB>TeO<SUB>5</SUB> increases as temperature increases attributed to the greater occupation of the higher excited state. PL intensity of Bi<SUB>1.9</SUB>Eu<SUB>0.1</SUB>TeO<SUB>5</SUB>, however, increases as temperature decreases attributable to the distinct emission mechanisms at different temperatures. PL measurements also strongly suggest that the Bi<SUP>3+</SUP> sites are in unsymmetrical coordination moieties within the framework.

Jo, H.,Han, S.,Park, J.,Choi, M.,Han, S.H.,Jeong, T.,Lee, S.Y.,Kwak, J.H.,Jung, Y.H.,Kim, I.S. Pergamon Press 2016 Tetrahedron Vol.72 No.4

<P>The rhodium(III)-catalyzed mild and site-selective C-H allylation of 2-arylbenzo[d]thiazoles and 2-arylbenzo[d]oxazoles with allylic phosphonates and allylic carbonates is described. This transformation provides an efficient construction of C2-allylated, crotylated and prenylated 2-arylbenzo[d] thiazoles and 2-arylbenzo[d]oxazoles. In addition, this protocol can be applied to the formation of 2-arylbenzo[d]thiazole scaffolds containing an allylic alcohol group by using of 4-vinyl-1,3-dioxolan-2-one and vinyl oxirane as coupling partners.

Single bubble dynamics on hydrophobic-hydrophilic mixed surfaces

Jo, H.,Park, H.S.,Kim, M.H. Pergamon Press ; Elsevier Science Ltd 2016 INTERNATIONAL JOURNAL OF HEAT AND MASS TRANSFER - Vol.93 No.-

Single bubble dynamics of distilled water were experimentally investigated on hydrophobic-hydrophilic mixed surfaces with hydrophobic dot diameters ranging from 50μm to 6mm. The heterogeneity of surface wettability could affect interfacial dynamics and cause the pinning phenomenon of the bubble interface, a contact angle transition, a 'stick-slip' behavior, and the interface necking during bubble growth. The triple line of a bubble initiated from a hydrophobic dot was pinned at its edge where a singularity of the surface wettability occurs. During this contact line pinning, the contact angle of bubble interface decreased. When the contact angle decreased to equal the receding contact angle of a bare hydrophilic surface, the triple line moved outward rapidly; this is called 'slip' behavior. After such process, the nucleated bubble vertically elongated and subsequently departed from the surface. The contact angle transition during the pinning and departing behavior was described by considering the capillary length of the bubble determined by the vertical deformation of bubbles. Using the bubble dynamics on the heterogeneously patterned surface with compactly arranged 50μm dots, boiling heat transfer coefficient enhanced to 2.1 times that in the bare hydrophilic surface.

A highly sensitive and selective impedimetric aptasensor for interleukin-17 receptor A

Jo, H.,Kim, S.K.,Youn, H.,Lee, H.,Lee, K.,Jeong, J.,Mok, J.,Kim, S.H.,Park, H.S.,Ban, C. Elsevier Applied Science 2016 Biosensors & bioelectronics Vol.81 No.-

Interleukin-17 receptor A (IL-17RA) has been recognized as a valuable biomarker for diverse diseases, including autoimmune diseases. In this work, an electrochemical biosensor with great sensitivity and selectivity toward IL-17RA was fabricated using an IL-17RA aptamer (K<SUB>d</SUB>=14.00nM) for the first time. The aptasensor was manufactured using electrodeposition of gold nanoparticles, and then quantitative detection of IL-17RA was performed based on impedimetry. The developed sensor exhibited a superior analytical performance for IL-17RA with a wide dynamic range of 10-10,000pg/mL in buffer and a detection limit of 2.13pg/mL, which is lower than that of commercially available ELISA kits. In addition, we validated the high specificity of the designed aptasensor to only IL-17RA, which showed good sensitivity even in human serum solution. Furthermore, the detection of the differentiated HL-60 cells expressing IL-17RA was successfully performed. Clinical applicability of the sensor was also demonstrated utilizing neutrophils separated from asthma patients. It is expected that the fabricated aptasensor will become an excellent diagnostic platform for IL-17RA-mediated diseases.

Fast prime number generation algorithms on smart mobile devices

Springer Science + Business Media 2017 CLUSTER COMPUTING Vol.20 No.3

<P>As smart mobile devices are widely used, mobile threats are more serious, so security in mobile becomes more and more important. However, the performance of these devices are not powerful enough to use the same security algorithms as PCs. Public key cryptosystems such as RSA need big primes to enhance the security, however, generating a big prime takes substantial time even on a PC. In this paper, we study two prime generation algorithms for smart mobile devices. First, we analyze a previous prime generation algorithm using a GCD test, named PGCD-MR, and show it sometimes performs inferior to the traditional TD-MR test. Second, we propose a new GCD test, named m-bit GCD-MR, for fast prime generation in both PCs and smart mobile devices. We compare the running times of PGCD-MR, m-bit GCD-MR, and TD-MR combinations on PCs and Samsung Galaxy Tab 10.1. The experimental results show our running time analysis is accurate (only 2% error) and m-bit GCD-MR test is the fastest among three prime generation algorithms. More exactly, m-bit GCD-MR test is about 20% faster than the TD-MR combination.</P>
