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.

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>

Rhodium(III)-catalyzed heteroatom-directed C-H allylation with allylic phosphonates and allylic carbonates at room temperature

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.

Application of whole‐exome sequencing for detecting copy number variants in CMT1A/HNPP

Jo, H.‐,Y.,Park, M.‐,H.,Woo, H.‐,M.,Han, M.H.,Kim, B.‐,Y.,Choi, B.‐,O.,Chung, K.W.,Koo, S.K. Blackwell Publishing Ltd 2016 Clinical genetics Vol.90 No.2

<P>Large insertions and deletions (indels), including copy number variations (CNVs), are commonly seen in many diseases. Standard approaches for indel detection rely on well‐established methods such as qPCR or short tandem repeat (STR) markers. Recently, a number of tools for CNV detection based on next‐generation sequencing (NGS) data have also been developed; however, use of these methods is limited. Here, we used whole‐exome sequencing (WES) in patients previously diagnosed with CMT1A or HNPP using STR markers to evaluate the ability of WES to improve the clinical diagnosis. Patients were evaluated utilizing three CNV detection tools including CONIFER, ExomeCNV and CEQer, and array comparative genomic hybridization (aCGH). We identified a breakpoint region at 17p11.2‐p12 in patients with CMT1A and HNPP. CNV detection levels were similar in both 6 Gb (mean read depth = 80×) and 17 Gb (mean read depth = 190×) data. Taken together, these data suggest that 6 Gb WES data are sufficient to reveal the genetic causes of various diseases and can be used to estimate single mutations, indels, and CNVs simultaneously. Furthermore, our data strongly indicate that CNV detection by NGS is a rapid and cost‐effective method for clinical diagnosis of genetically heterogeneous disorders such as CMT neuropathy.</P>

DYNAMIC SENSOR ZEROING ALGORITHM OF 6D IMU MOUNTED ON GROUND VEHICLES

J. OH,최세범 한국자동차공학회 2013 International journal of automotive technology Vol.14 No.2

The main focus of this paper is to compensate the steady state offset error of the 6D IMU which provides the measurements that include the vehicle linear accelerations and angular rates of all three axes. Additionally, the sensor compensation algorithm exploits the wheel speed data and the steering angle information, since they are already available in most of the modern mass production vehicles. These inputs are combined with the inverse vehicle kinematics to estimate the steady state offset error of each sensor inputs as it is done in a disturbance observer, and the raw sensor measurements are compensated by the estimated offset errors. The stability of the error dynamics regarding the integrated signal processing system is verified, and finally, the performance of the system is tested via experiments based on a real production SUV.
