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.

The antiinflammatory mechanism of NSAIDs is attributed to the reduction of prostaglandin synthesis by the direct inhibition of cyclooxygenase. Inhibition of prostaglandin production in organs such as stomach and kidney can result in gastric lesions, nephrotoxicity and increased bleeding. In this study, newly designed COX-2 inhibitors, synthesized 1,2-benzothiazine derivatives, were screened in vitro for selectivity of COX-1 and COX-2 inhibition properties. Lead compounds in the structure-activity relationship were studied to synthesize new highly selective COX-2 inhibitors. To determine inhibitory effect of COX-2, synthesized 1,2-benzothiazine derivatives were screened with accumulation of prostaglandin by lipopolysaccharide (LPS) in aspirin-treated macrophages and murine macropharge cell. Some of synthesized 1,2-benzothiazine derivatives were shown to be effective as selective COX-2 inhibitory activity. Others exhibited a preferential inhibition of COX-2, although some COX-1 inhibitory activity was still present. As a conclusion, simple monomer derivatives were more active than dimer derivatives. Substitution of halogen (Br, Cl) on the benzothiazine nucleus slightly enhanced inhibition activity.

The blood supply and metabolism of malignant nodules are qualitatively and quantitatively different from those of most benign nodules. We evaluated the efficacy of dynamic CT for differentiation of benign malignant lesions. Thirty-six patients with malignant nodule(n=20), tuberculoma(n=7), and pneumonic consolidation(n=9) were evaluated by thin section dynamic CT. CT numbers of lesion and aorta were measured before enhancement, and 1 minute, and 3 minutes after enhancement. Malignant lesions(maximum, 31.1±10.7 HU) enhanced significantly more than tuberculoma(maximum, 13.5±12.9 HU), but mass/aorta ratios were not so significantly different between malignant lesions(maximum, 0.61±0.27), tuberculoma(maximum, 0.36±0.15), and pneumonic consolidation(maximum,0.49±0.14). Dynamic CT is very useful for differentiation of malignant lesions from tuberculoma.

It is Important to know the normal size, shape, and signal intensity of anterior cruciate ligament in the evaluation of knee injury Many studies have reported findings of tear or rupture as well as normal anatomy of these structure, especially with MR images. To our knowledge, there are few studies about normal structures of anterior cruciate ligament in MR images. The purpose of this study is to compare normal finding with tear of anterior cruciate ligament on MRI. Twenty-three cases with rupture of anterior cruciate ligament were evaluated on MRI, measuring the length, thickness, width of anterior cruciate ligament, and angles of anterior and posterior cruciate ligaments. Mean length, thickness, and width of anterior cruciate ligament in patients with rupture were 37.7±4.8mm, 9.0±1.2mm, 8.0±0.8mm, and mean angles of anterior cruciate ligament, and posterior cruciate ligament were 48.1±9.6˚, 118.8±13.1˚. Curvature ratio of posterior cruciate ligament was 0.25±0.09. The results showed significant differences between normal persons and patients with complete or partial rupture, and the mean angle and curvature ratio of posterior cruciate ligament which are known to related with indirect sign in tear of anterior cruciate ligament showed significant differences between ours and that of western countries. These results will be useful in the evaluation of patient wish rupture of anterior cruciate ligament, especially on MRI.

For the selective candidates of COX-2 inhibitors, we designed new NSAIDs which is the hydantoin ring based structure substituted with two planar aromatic ring. Seven O-alkyl a-anilinophenylacetate were synthesized through the base-catalysis hydrolysis of 1,5-diarylhydantoins and O-alkylation of sodium a- anilinophenylacetate with alkyl halides. To evaluate inhibitory effect of COX-2. synthetic hydantoin ring based derivatives were screened with accumulation of prostaglandin by lipopolysaccharide in aspirin-treated murine macropharge cell. Most of these compounds inhibited less than 60% of the prostaglandin E_(2) production at a concentration of 10μg/mL.

Background : Microvascular angina or syndrom X is heterogenous and encompasses different pathogenetic entities. Several studies suggest that microvascular angina have good prognosis and occurs predominantly in postmenopausal women. Lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and fibrinogen are the independent risk factor of acute coronary syndrome and are the chief underlying cause of atherosclerosis. We investigated clinical characteristics and markers in patients with microvascular angina. Methods : We studies 23 patients diagnosed with microvascular angina and 16 control group with negative treadmill exercise test and no significant coronary angiogram. We investigated clinical characteristics in patients group and evaluated symptom during a follow-up period of 4.2± 2.5 month. Exercise time in treadmill exercise test was compared between patients and control group. We assessed the level of markers, such as lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and ESR in two groups. Results : There is no difference in age between two groups. Patients group had a tendency to increase in female, hypertension, DM, and smoking history, but there was no statistical significance difference. Exercise duration time was significantly decreased in patients with microvascular angina (p<0,05). Serum lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholestrol, Triglyceride, ESR, Fibrinogen and Homocystein value were no significant difference between microvascular angina and control group. Only CRP was significantly high in patients with microvascular angina (p<0.05). Conclusion : There was no statistical significance difference in age, sex, hypertension, DM and smoking history between two groups but patients group had a tendency to increase the prevalence in hypertension, DM and smoking history, female. Also, Symptom improvement and disappearance in follow-up was presented in 11 patients of 19(57.9%). Exercise tolerance was worse in patients group than control group. CRP value was significantly higher in patients group than control group. There was no statistical significance difference in lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, ESR and Fibrinogen between two groups.

Accurate staging of lung cancer is essential for defining operability, selecting treatment regimens, predicting survival, and reporting comparable end results. Revisions in stage grouping of the TNM subsets in the International System for Staging Lung Cancer have been adopted by the American Joint Committee on Cancer and the Union Internationale le Cancer at 1996. We compared the previous TNM systems with revised stage grouping rules, and tried to applicate the new size-criteria for metastatic lymph nodes in mediastinum. Twenty-two patients were undergone CT stagings by using three different systems of previous, revised, and modified TNM subsets. Ten patients showed different TNM stage by the revised stage grouping rules and seven patients were altered in lymph node stage by the new size-criteria. Recognition of revised stage grouping rules is very important for treatment plan and predicting the correct prognosis.

대학생 학습과정 조사도구의 비교·분석 연구

신현석,변수연,박해경 한국교육방법학회 2012 교육방법연구 Vol.24 No.1

Higher education institutions in the 21st century are feeling more and more pressure to show and prove their due accountability toward the society. The fulfillment of their social responsibilities can be accomplished by teaching and research. The quality of teaching in higher education institutions have been approached from various perspectives and tried to be measured by different methods. Among others, students' evaluation and ratings have been viewed as useful tools to evaluate the quality of education and supporting services of the institutions. This study analyzed 5 aspects of the three major student's evaluation and engagement questionnaires: National Survey of Student Engagement, Course Experience Questionnaire, Australian Survey of Student Engagement. In comparative analysis, researchers concluded CEQ has several shortcomings to be an efficient and effective student engagement scale while it still has some merits such as offering a opportunity to every college graduate to evaluate their college teaching experience. NSSE and AUSSE, taking the sample study framework, are reviewed to be easier to be administrated and contain more plentiful information about various facets of college students' experience and its relationship with achievements in college. This findings are expected to offer useful implications to those who develop the Korean scale of student experience and engagement. 본 연구는 세계적으로 사용되고 있는 대학생 학습과정 조사도구들 중 NSSE, CEQ, AUSSE의 개발 배경과 변천 과정, 개발 목적, 주요 내용, 결과의 활용 다섯 가지 측면을 조사한 후 이를 비교․분석함으로써 우리나라 고등교육기관의 대학생 학습과정 조사도구 개발을 위한 정책적 시사점을 제안하는 것을 목적으로 한다. 이들을 비교한 결과 다섯 가지 준거를 통한 비교․분석 결과 대학 강의 경험을 주요 내용으로 하는 전수조사 방식의 CEQ보다는 강의와 강의실 밖의 다양한 학습 기회에 대한 학생 참여도를 기준으로 대학생의 학습과정과 대학 교육의 질을 평가하는 표본조사 방식의 NSSE와 AUSSE가 우리의 고등교육 시스템에 더 적합할 뿐만 아니라 국제적 비교․분석도 가능한 조사도구로 평가되었다.

The purpose of this study was to assess the changes in quality of life wish elapse of chemotherapy in head and neck cancer patients. This study was a longitudinal descriptive design. The subjects were 9 patients who had stage III and stage IV head and neck cancer and received neoadjuvant cisplatin and 5-fluorouracil chemotherapy. Linear Analogue Self Assessment Scale (LASA) of the QOL which it includes eleven items(seven physical items appetite, nausea/vomiting, physical well-being, vigor activity, energy, sleepiness, fatigue and four mental items anger, anxiety, depression & vital power) were used to assess the quality of life eleven times(once in the prechemotherapy period and from the 1st day to 10th day postchemotherapy). The means of scores at each time were analyzed by repealed measures of ANOVA and Bonferroni multiple comparison method. The results are as follows : 1. The degree of appetites decreased significantly on the period between third and sixth day compared with that of appetites on the prechemotherapy day (p<0.001). 2. The degree of physical well-being decreased significantly on the period between first and fifth day compared with that of physical well-being on the prechemotherapy day (p<0.001). 3. The degree of nausea/vomiting decreased significantly on the period between first and fourth day compared with that of appetites on the prechemotherapy day (p<0.001). 4. The degree of anger decreased significantly on the second, fourth, eighth and ninth day after chemotherapy compared with that of anger on the prechemotherapy day(p<0.001). 5. The degree of fatigue decreased significantly on the fourth day compared with that of fatigue on the prechemotherapy day(p<0.001). 6. The increment of nausea/vomiting and poor appetite started on the 2.89th day and 3.67th day after chemotherapy, respectively. 7. The increment of sleepiness started on the 2.56th day after chemotherapy. 8. The increment of depression and anxiety started on the 2.33th day and 3.33th day after chemotherapy, respectively. 9. The lowest degrees of nausea/vomiting and poor appetite were 37.00±17.9 % and 28.64±14.94 % after chemotherapy compared with those of nausea/vomiting and poor appetite on the prechemotherapy day, respectively. 10. The lowest degrees of anger and vigor activity were 48.12±28.3 % and 39.83±24.9 % after chemotherapy compared with those of anger and vigor activity on the prechemotherapy day, respectively. 11. The recovery rates of eight items of quality of life (appetite, vigor activity, energy, fatigue, anger, anxiety, depression & vital power) were shown to reach a peak on the tenth day after chemotherapy and be reached to almost 84 % compared with those of quality of life on the prechemotherapy day. 12. The recovery rates of physical well-being and sleepiness were shown to reach to 67.75 % and 95.68 % on the 10th day after chemotherapy compared with those of physical well-belong and sleepiness on the prechemotherapy day. 13. The recovery rates of seven physical items were faster than those of four mental items on the 10th day after chemotherapy. In conclusion, it is suggested that nursing care strategies to improve the quality of life in patients with chemotherapy would be established both physically and mentally, and be extended at least ten days when patients stayed their home after chemotherapy.
