This study was performed to develop a standardized recipe for yuza pyun made of citron juice that is by-product of citron tea, to increase the utilization of citron. The effects of mungbean starch(15%, 18%) and dilution ratio of yuza extract(100%, 75%, 50%) on the quality characteristics were evaluated. The quality characteristics of the samples were estimated in terms of sweetness, color difference, texture profile analysis and sensory evaluation. Sweetness of the 18% mungbean groups were higher than 15% groups(p<0.001). The values of Hunter color system indicated that higher content of yuza extract tended to increase yellowness significantly(p<0.001). Texture profiles of hardness, adhesiveness, springiness, cohesiveness, gumminess of yuzapyun showed no significant differences among samples. For sensory evaluation, color and sourness were decreased as yuza extract was diluted, whereas elasticity and sweetness were increased. Yuza pyun containing 18% of mungbean starch with 50% diluted extract was the most preferred in overall acceptability. According to multiple regression analysis, color, sweetness, elasticity and sourness(in order) were important control factors in overall acceptability.

Pyun, Danielle O., Chung, Miri K. & Choi, Ho Jung. 2013. KFL learners’ acquisition of Korean locative particles: A corpus-based contrastive interlanguage analysis. Language Information. Volume 17. 23-46. Adopting the contrastive interlanguage analysis methodology, this study investigates KFL (Korean as a Foreign Language) learners’ acquisition of Korean locative case particles. A learner corpus compiled from eighty-seven intermediate learners of Korean was compared with a native speaker corpus on the frequency distribution of the five semantic categories of the Korean locative case (i.e, static location, dynamic location, time, goal, and source). In addition, learner errors on the use of locative case particles were quantified and examined according to the five semantic categories. The results of this study showed that KFL learners’ use of locative case particles substantially deviated from native speakers’ usage in frequency. Learners’ inaccurate and limited use of locative case particles were attributed to such factors as L1 transfer, overgeneralization, prior input, and interlanguage development.

Nitrile-forming eliminations from $(E)-2,4,6-(NO_2)_3C_6H_2CH=NOC_6H_4-2-X-4-NO_2$ (1) promoted by $R_3NH/R_3NH^+$ in 70 mol % MeCN(aq) have been studied kinetically. When X = $NO_2$, the reactions exhibited second-order kinetics as well as Br$\"{o}$nsted ${\beta}$ = 0.63 and ${\mid}{\beta}_{lg}{\mid}$ = 0.34-0.46, and an E2 mechanism is evident. As the leaving group was made poorer (X = H, Cl, and $CF_3$), Br$\"{o}$nsted ${\beta}$ value increased from 0.63 to 0.85-0.89 without much change in the ${\mid}{\beta}_{lg}{\mid}$ value E2, indicating that structure of the transition state changed to an E1cb-like with extensive $C_{\beta}-H$ bond cleavage, significant negative charge development at the ${\beta}$-carbon, and limited $C_{\alpha}$-OAr bond cleavage.

OBJECTIVE: This study examined whether epistasis between single nucleotide polymorphisms (SNPs) within proprotein convertase subtilisin/kexin type 1 (PCSK1) and dopamine &bgr;-hydroxylase (DBH) genes is associated with premature ovarian failure (POF). METHODS: One hundred twenty women with POF and 222 female controls were recruited for this study. To genotype SNPs within PCSK1 and DBH, we used a GoldenGate assay with VeraCode technology, which uses an allele-specific primer extension method. RESULTS: Two SNPs (rs155979 and rs3762986) within PCSK1 and one SNP (rs1611114) within DBH, which were located in the 5&vprime; flanking region, were involved in synergistic interactions. The C allele in the rs155979 SNP showed an increased risk of POF in a dominant model when AA genotype in the rs1611114 SNP was present (odds ratio, 3.60; 95% CI, 1.82-7.14; P = 0.00024), whereas the G allele in the rs1611114 SNP showed a reduced risk of POF in a dominant model when at least one C allele at the rs155979 SNP was present (odds ratio, 0.24; 95% CI, 0.11-0.51; P = 0.00018) or one G allele at the rs3762986 SNP was present (odds ratio, 0.33; 95% CI, 0.19-0.60; P = 0.00023). CONCLUSIONS: Epistases between SNPs within PCSK1 and DBH genes are significantly associated with susceptibility or resistance to POF.
Epistasis between polymorphisms in TSHB and ADAMTS16 is associated with premature ovarian failure

OBJECTIVE: This study investigated whether epistasis between single nucleotide polymorphisms (SNPs) within the TSHB (thyroid-stimulating hormone &bgr;) and ADAMTS16 (ADAM metallopeptidase with thrombospondin type 1 motif, 16) genes is associated with an increased risk of premature ovarian failure (POF) in Korean women. METHODS: In stage I, 120 women with POF and 222 controls participated. A GoldenGate assay with VeraCode technology was used to genotype SNPs within the TSHB and ADAMTS16 genes. For stage II, we obtained genotype data merged with imputed data for 1,641 female controls from the Korean Genome Epidemiology Study. RESULTS: In stage I, two SNPs (rs7530810 and rs1321108) in the 5&vprime; flanking region of the TSHB gene demonstrated significant synergistic interactions with one tagging intronic SNP (rs13172105) in the ADAMTS16 gene (odds ratios, 6.63 and 5.57; 95% CIs, 2.30-19.18 and 2.05-15.12; P = 0.00048 and 0.00074, respectively) although the SNPs were not significantly associated with POF in a single SNP model. When at least one G allele at rs7530810 or one A allele at rs1321108 was present in combination with a C allele at rs13172105, significant synergistic effects were observed in a recessive model. In stage II and combined analyses, the same combinations repeatedly showed significant synergistic interactions. CONCLUSIONS: Epistasis between SNPs within the TSHB and ADAMTS16 genes may increase the risk of POF in Korean women.

<P>A new electron scattering apparatus is developed based on concepts from the positron system built by Surko <I>et al</I> (1988). In an electron version of the system, the electron beam is provided by a cathode and the rest of the system is correspondingly modified to a simpler system. The system was tested by measuring electron scattering from argon to verify its operation. N<SUB>2</SUB>O is important in the atmosphere and plasma processes, and in the intermediate energy region from 5 eV to 50 eV, there are two previous results for the electron scattering total cross-section which are in disagreement. We present here a new measurement for the total electron cross-section of N<SUB>2</SUB>O, helping to resolve this disagreement.</P>
