Acetylcholine inhibited NE-evoked contraction in endothelium-intact vessels, and this was markedly impaired in DJ-1/park7<SUP>−/−</SUP> mice compared with DJ-1/park7<SUP>+/+</SUP>. Nitric oxide (NO) production (82.1 ± 2.8% of control) and endothelial NO synthase (eNOS) expression (61.7 ± 8.9%) were lower, but H<SUB>2</SUB>O<SUB>2</SUB> production (126.4 ± 8.6%) was higher, in endothelial cells from DJ-1/park7<SUP>−/−</SUP> mice than in those from DJ-1/park7<SUP>+/+</SUP> controls; these effects were reversed by DJ-1/park7-overexpressing endothelial cells from DJ-1/park7<SUP>−/−</SUP> mice. Histone deacetylase (HDAC)-1 recruitment and H3 histone acetylation at the eNOS promoter were elevated and diminished, respectively, in DJ-1/park7<SUP>−/−</SUP> mice compared with DJ-1/park7<SUP>+/+</SUP> controls. Moreover, SBP was significantly elevated in DJ-1/park7<SUP>−/−</SUP> mice compared with DJ-1/park7<SUP>+/+</SUP> controls, but this elevation was inhibited in mice treated with valproic acid, an inhibitor of Class I HDACs including HDAC-1.</P><P><B>Conclusion</B></P><P>These results demonstrate that DJ-1/park7 protein may be implicated in the regulation of vascular contractility and blood pressure, probably by the impairment of NO production through H<SUB>2</SUB>O<SUB>2</SUB>-mediated epigenetic inhibition of eNOS expression.</P>

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

본 연구의 목적은 동국대학교의 교수들이 수행하고 있는 교수학습 방식을 파악하고 각 방법들의 효과성을 교수들이 어떻게 인식하고 있는지를 알아 보고자 하였으며 창의적 교수학습방법개발에 대한 교수들의 요구를 파악하여 교수학습개발센터의 프로그램개발을 위한 기초자료로 삼고자 하였다. 수업방식에 있어서 전공, 교양을 막론하고 대부분이 강의식 수업방식이 높았으며(80.9%, 86%), 발표식, 토론식이 (14%, 18.6%) 실험실습 등이 그 다음으로 나타났다. 교수들은 전공과목보다는 교양수업에서 학생들의 요구에 맞는 수업 수업방식을 고려하고 있는 반면 수업방식의 효과에 대해 53%만이 효과적이라고 보고하고 있다. 교수들도 효과적인 강의방법 등 교수법에 대해 체계적으로 학습할 필요성을 느끼고 있었다. 강의 기술(교수방법)과 토론 중심 수업 방법에 대한 워크샵에 대한 요구가 가장 높게 나타났고 발표수업과 프로젝트수업 방법 등 강의식 수업 이외의 다른 수업방식에 대한 워크샵 요구도가 높았다. 그 외에 학교의 지원에 대해서는 첨단 수업 기자재 활용을 위한 보조자(조교)에 대한 요구도가 가장 높고 강의 운영을 위한 보조금, 개인별 상담 지원 순으로 요구도가 높게 나타났다. The purpose of this study was to comprehend the methods of teaching and learning carried out by the teachers of Dongguk University, and to find out how the professors found those methods effective. This research was also used to serve as a basis for the development of a more creative teaching-learning system to enhance better programs for the Professor Teaching-Learning Development Center. In teaching methods, regardless of classes for majors or for cultural enrichment, most of the courses were in the form of lectures (80.9%, 86%) followed by research and discussion (14%, 18.6%), with experiment and practical training coming in third. Although professors tend to choose a more student-oriented class method in distribution courses more than in major courses, it was reported that only 53% of the faculty claimed this class method to be effective. The faculty felt the need for professors to have more constructive learning in incorporating more effective teaching methods. The demand for professor workshops on teaching skills (teaching methods) and discussion oriented classes proved to be high, as well as the need for workshops on teaching methods other than lectures, such as research courses and project oriented class methods. Regarding other demands for university support, the demand for an assistant (assistant teacher) to help with the new technology equipment was the highest, followed by subsidies for course management and support in individual counseling.

On the Long-distance Scrambling/Phonological Suppression of Adjuncts in Korean

Park, Myung-Kwan, Shin, Ui-Jong. 2017. On the Long-distance Scrambling/ Phonological Suppression of Adjuncts in Korean. Studies in Generative Grammar, 27-3, 675-695. This paper examines the syntactic aspects of adjuncts in Korean, particularly when they undergo long-distance scrambling or phonological suppression. It is noted that, unlike argument elements, though apparently distantly scrambled, they cannot be reconstructed into downward embedded clauses. It is also noted that not all adjuncts but non-nominal manner or reason adverbials are disallowed from being phonologically suppressed in the structural environments where arguments in general are allowed to be phonologically null. However, the otherwise illegal reconstruction or recovery of distantly-displaced or phonologically silent adjuncts is made successful as part of the corresponding process for argumental elements that they adjoin to. In essence, we attribute the argument vs. adjunct distinction to the labeling processing that arguments and adjuncts enter into in different ways.

Gui-Sun Moon, Sun-Woong Kim, Jeong-Ah Shin, Hae-Kyung Wee, Jong Un Park, Myung-Kwan Park, and Wonil Chung. 2018. Voice Mismatch Meets Neurolinguistics. Studies in Modern Grammar 99, 85-115. This paper aims to investigate Korean advanced L2 English learners’ strategies for ellipsis resolution during sentence processing. Ellipsis resolution is known to involve several stages of information processing from the initial step of detecting an ellipsis-licensing element by the parser to the final stage of integrating the ellipsis site with the information retrieved from the antecedent of the ellipsis site. In examining these steps, we have manipulated three factors: (i) TP vs. VP-ellipsis; (ii) two types of discourse coherence relations (resemblance(-contrast) vs. cause-effect relations); (iii) voice match vs. mismatch. We found through the ERP recordings that voice mismatch in TP ellipsis elicited N400, followed by P600, irrespective of discourse coherence relations. In contrast, voice mismatch in VP-ellipsis registered N400 only in resemblance(-contrast) relation, but not in cause-effect relation. These findings lead us to conclude that Korean advanced L2 learners of English seem to undergo the full sequence of processing stages required for ellipsis resolution.

Objectives: This study was performed to evaluate whether there is the difference of graft height changes in radiographic evaluation in single implants and multiple implants after maxillary sinus floor augmentation with an auto-xenograft mixture. Methods: The study group comprised 29 patients (16 men, 13 women; mean age, 56.5±12.4 years; range, 27 to 87 years) treated at the implant clinic of the Ewha Womans University Mokdong Hospital. They were treated with the sinus floor augmentation of lateral window technique and simultaneous placement of dental implants. Their implants have been evaluated for 42.4±10.5 months. To evaluate the height of grafted material, the real implant length was compared with that of panoramic radiography evaluated by a digital caliper (PACS program), and then the real height of grafted material was assumed. SPSS 19.0 was used in statistical analysis. Wilcoxon singed rank test was utilized for P value and Mann-Whitney for statistical significance in the changes of grafted height between single implants and multiple implants. The level of statistical significance was defined as P<0.001. Results: The evaluated graft height in single implants' group decreased to 0.60±0.54 mm at the time of delivery (after 7.5 months, P=0.001), in multi-unit implants' group to 0.96±0.84 mm (after 6.5 months, P<0.001). The evaluated graft height in single implants' group decreased to 1.11±0.75 mm at the last follow-up (after 43.5 months, P=0.001), in multi-unit implants' group to 1.52±0.99 mm (after 41.8 months, P<0.001). Mann-Whitney test was used for the difference between single implants and multi-unit implants. There was no difference in two groups at the time of delivery and the last follow-up (P>0.001). Conclusion: There was no statistical significance of radiographic graft height after maxillary sinus floor augmentation between single implants and multiple implants.
