Dugas, Andre´ 서울대학교 어학연구소 1992 語學硏究 Vol.28 No.4
The linguistic fund, that is, the actual lexical inventory of a language, is always considerably larger than the sum total of the contents of dictionaries for that language. It corresponds to all the possibilities of derivation and compounding―with the associated word-formation rules. The exploitation of the latter within machine-readable dictionaries should therefore allow a far more accurate coverage of the linguistic fund, by generating thousands of additional entries, some being more or less widely attested in their written form, some representing the set of virtual words generated by a productive rule that have not, for one reason or another, been recognized as existing words. Note that the boundary between the two subsets is not clearcut. The conditions which determine whether a generated form will belong to one or the other have not given rise to extensive studies, neither in linguistics nor in lexicology, in spite of their significance for a better understanding of lexical creativity and word-formation processes. The relevance of such phenomena seems to have been greatly underestimated―as is indicated by the fact that no studies have been fulfilled on the topic of words such as me´dico-le´gal and franco-que´be´ cois. We will demonstrate and illustrate for the French language the shortcomings of the simple compiling method and how ignoring them has led to unnecessary complications in the field of electronic lexicography.

Realization of Excellence in Korean Higher Education
David W.Dugas 대전대학교 지역협력연구원 2002 지역학연구 Vol.창간 No.-
Reform of higher education in Korea has prompted a lot of institutional activity, but many universities have not matched improvements in physical infrastructure with changes in their educational programs. This essay presents concepts developed during educational reform at universities in advanced English-speaking countries during the last few decades. To begin, creation of an educational program pertinent to the needs and deficits of a target group could be accomplished by surveying their needs and desires. The informed result should be lean curricula able to fulfill specified educational goals for each major. For a program to be called integrated, each syllabus should advance the goals of the curriculum it supports. Ideally, each syllabus would contain content and process goals which would provide bases for assessment. By planning class activities in consideration of the interests and abilities of specific groups of students, teachers might provide a more satisfying educational experience. Assessment must be a permanent part of the administration of the university to provide answers to whether curricula and courses are successful or not. To retain better faculty, promotional policy should be re lated to clearly expressed goals rewarding a spectrum of desirable activities in addition to research. Attempts by teachers to improve their teaching and research should be supported by specific programs and resources. Such steps promote educational excellence.

Winston, Gary W.,Kim, Young Chul,Dugas, Alton J.,Castaneda-Acosta, Jose,Fischer, Nikolaus H. The Korean Society of Toxicology Korea Environment 2001 Toxicological Research Vol.17 No.-
We report on the applicability oj a method recently developed in our laboratory for measuring the antioxidant potential of isolated chemicals and extracts derived from natural products. Peroxyl radicals generated by thermal homolysis of 2,2'-azobis-amidinopropane (ABAP) oxidize $\alpha$-keto-${\gamma}$-methiolbutyric acid (KMBA) to ethylene, which is monitored by gas chromatography. Inhibition of ethylene formation in the presence of antioxidants that compete with KMBA for peroxyl radicals is the basis of the Total Oxyradical Scavenging Capacity Assay (TOSCA; Winston et al., 1998). Antioxidative activities of water-soluble extracts of American green tea, the anti-hepatotoxic flavonolignan from milk thistle (Silybum marianum) silybin, Ginkgo biloba extract EGb 761, and a series of naturally occuring sesquiterpene lactones (all ger-macranolides found in in fungi, liverworts, and plants) were studied. The specific TOSC value per $\mu$M silybin was 5.2, which is essentially comparable to that of Trolo $x^{ⓡ}$, a water-soluble vitamine E analog. Tea and Ginkgo extracts exhibited potent peroxyl radical scavenging capacity with values, respectively of =1700 and 1000 $\mu$mols Trolo $x^{ⓡ}$ equivalent per gram dry matter. The known anti-inflammatory activity of some germacranolides prompted study of their antioxidant capacity. None of the lactones exhibited antioxidant capacity toward peroxyl radicals comparable to Trolo $x^{ⓡ}$; costunilide, the most lipophilic, had a TOSC value = to glutathione. The potential role of peroxyl radicals in lipidperoxidation, other cellular damage, and var-ious disease states suggest a possible preventive role for silybin, green tea and Ginkgo biloba in oxidative stress caused by these free radical species.ecies.

Background: Sleep quality, quantity, and efficiency have all been demonstrated to be adversely affected by rotator cuff pathology. Previous measures of assessing the impact of rotator cuff pathology on sleep have been largely subjective in nature. This study was undertaken to objectively analyze this relationship through the use of activity monitors. Methods: Patients with full-thickness rotator cuff tears at a single institution were prospectively enrolled between 2018 and 2020. Waist-worn accelerometers were provided for the patients to use each night for 14 days. Sleep efficiency was calculated using the ratio of the time spent sleeping to the total amount of time that was spent in bed. Retraction of the rotator cuff tear was classified using the Patte staging system. Results: This study included 36 patients: 18 with Patte stage 1 disease, 14 with Patte stage 2 disease, and 4 patients with Patte stage 3 disease. During the study, 25 participants wore the monitor on multiple nights, and ultimately their data was used for the analysis. No difference in the median sleep efficiency was appreciated amongst these groups (P>0.1), with each cohort of patients demonstrating a generally high sleep efficiency. Conclusions: The severity of retraction of the rotator cuff tear did not appear to correlate with changes in sleep efficiency for patients (P>0.1). These findings can better inform providers on how to counsel their patients who present with complaints of poor sleep in the setting of full-thickness rotator cuff tears.
