Yoon, Seok-Hwa(1995). Null Operator Structures in English. Linguistics, Vol. 3. The purpose of this paper is ,to survey on null operator structures with special reference to English, and to provide adequate accounts for the phenomena and distribution of the null operators and the phenomena closely related to them, within the principles and parameters approach to the grammar of natural language. We assume that null operator structures involve predicational null operator structures and parasitic gap structures, but examine only predicational null operators. On the assumption that predicational null operators are ungoverned since predicational null operators are not complements but adjuncts to the matrix verb, Contreras(1989) argues that predicational null operators behave like PRO and are licensed by Control Theory.

On Parasitic Gap Stuctures in English

Yoon, Seok Hwa 대한언어학회 1996 언어학 Vol.4 No.-

Yoon, Seok-Hwa. 1996. On Parasitic Gap Structures in English. Linguistics 4, 145-168. The purpose of this paper is to survey on parasitic gap structures with special reference to English, and to provide adequate accounts for the phenomena closely related to them, within the principles and parameters approach to the grammar of natural language. We assume that null operator structures involve predicational null operator structures and parasitic gap structures, but examine only parasitic gap structures. The assumption that a governed null operator is a variable seems to be specific to adjunct-internal PG structures. But if we do not put any restriction on the Bijection Principle, typical adjunct PG structures will violate it. Furthermore, there are some exceptional adjunct PG structures for which the Modified Strong Binding Condition is not applicable. (Wonkwang University)

Syntactic Recoverability of Null Objects in Korean

Yoon, Seok Hwa 대한언어학회 1997 언어학 Vol.5 No.2

Yoon, Seok-Hwa. 1997. Syntactic Recoverability of Null Objects in Korean. Linguistics, 5-2, 271-288. The purpose of this paper is to survey James Huang's recent proposal regarding nominals with special reference to Korean, and to propose a new analysis on the syntactic recoverability of the null objects, and to present some theoretical implications of my analysis on parametic variation with Chomsky's principles and parameters approach in syntax. So far I have argued that some functional phrases are existent and behave like dynamic elements in Korean syntax although the existence of functional categories such as AGRPs is minimally attested in its morphology.

Neuropathic Pain의 동물모델에서 유발된 Thermal Hyperalgesia에 대한 Clonidine의 효과

윤석화,오세철,최세진 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.2

The effects of intraperitoneal injection(i.p.) of the alpha 2 adrenal receptive agonist, clonidine on the thermal hyperalgesia produced by unilateral patially tight ligation of the sciatic nerve was studied in rats. First in the preoperative and postoperative Mays, paw withdrawal latency of both hind paw(lesioned,unlesioned) with heat stimulant was tested. After that, each groups of rats injected saline, clonidine 10㎍/kg, or clonidine 50㎍/kg. I.p.10㎍/kg and 50㎍/kg clonidine, paw withdrawal latency of lesioned side significantly reduced than saline group. It is suggested systemical clonidine may be useful in treating neuropathic pain in humans.

윤석화,김일문,이상묵,유재현 충남대학교 의과대학 지역사회의학연구소 1996 충남의대잡지 Vol.23 No.2

To compare the airway resistance effects of two heat and moisture exchangers(HME) during short-term intraoperative volume controlled mechanical ventilation. Following a randomized order, the patients were ventilated during 3hrs with two HMEs(Pall conserve and Humi-vent filter). In each patient and for each 5 min, lhr, 2hrs and 3 hrs period, body temperature and airway resistance were measured. The hydrophobic HME (Pall conserve) had a good theraml conservation capacity, but increase airway resistance(11.7±2.9cm H_2O/1/s to 15 4±3.4 after lhr, to 17.3±2.5 after 2hrs, to 17.5±3.3cm H_2O/l/s after 3hrs). The hygroscopic filter(Humi-vent filter) had a good thermal conservation capacity, and less increase airway restance than Pall conserve(13.0±2.3 to 15. 4±3.4. after 1hr, 15.9±2.5 after 2hrs, 15.0±3.3 cmH2O/I/s after 3hrs). The hygroscopic HME had a thermal and humidification capacity and less increase the airway resistance.

윤석화,강현호 원광대학교 대학원 2007 論文集 Vol.39 No.-

The purpose of this dissertation is to find out the effects of a fast reading program by presenting various prior theories and teaching and learning reading skills such as skimming, scanning, guessing, reading faster, etc. It's expected that such a study gives will help students develop abilities in reading for pleasure, reading comprehension skills, thinking skills and reading faster. Reading for pleasure is the easiest way to become a reader in English. It's also the most important way to improve one's reading abilities. Chapter Ⅰ discusses the necessity, purpose and scope of the present dissertation. Chapter Ⅱ deals with the work method that is composed of the subject and time period of the study and hypothesis. The first hypothesis will be a significant difference in the scores of reading comprehension ability between the experimental class and the control class. The second hypothesis, will be a significant difference in the scores of words per minute between the experimental class and the control class. To verify these hypotheses, the subjects were 124 male students in two classes of the second grade of J High School located in Kunsan City in Jeonbuk. The experimental class consisted of 62 students, and the control class consisted of 62 students. The period of the experiment was 12 weeks, from March, 2006 to August 2006. The instruction methods for speed reading training were, 1) The position of slash 2) Pre-reading activities 3) Chunking 4) Scanning 5) Skimming, and 6) Pattern of Organization. The results were analyzed by SPSS (Statistical Packages for Social Sciences). Chapter Ⅲ. The results of the study can be summarized as follows ; the scores of reading comprehension in the experimental class gradually increased in comparison with the control class. There was a significant difference in the reading comprehension test between the experimental class and the control class. Chapter Ⅳ. Through the results of this study, it would seem that speed reading training enhances students' reading comprehension ability. It's expected that such a study will give some abilities to students in the areas of reading for pleasure, reading comprehension skill, thinking skills and reading faster. Reading for pleasure is the easiest way to become a reader in English. It's also the most important way to improve one's reading abilities. Ongoing immersion in extensive reading is essential for practicing and applying reading skills and for developing all areas of language skill. I think that this dissertation is results can be applied to classroom teaching and will add to students' motivation for improving their reading rate and reading faster.

Changes of peripheral arterial oxygen saturation(SaO_2) were compared according to the methods of extubation after general anesthesia in 44 pediatric patients in TaeJon ST.Mary's Hospital between March and May in 1992. Patients were divided in two groups. Group Ⅰ (n=22); endotracheal extubation was performed with suctioning by catheter after one or two endotracheal suctions. Group Ⅱ (n=22); endotracheal extubation was performed wit positive pressure administration of 100% oxygen by reservoir bag simultaneously after one or two endotracheal suctions. All patients were administered 100% oxygen for one minute after extubation and transferred to recovery room and administered oxygen 3ℓ/min by face mask for three minutes. The results are as follow: 1) SaO_2 was decreased significantly (p<0.05) after extubation in group Ⅰ compared with control and group Ⅱ. 2) The number of patients whose SaO²bellow 95% are increased in group Ⅰ(77%) compared group Ⅱ(5%) after endotracheal extubation. 3) SaO_2 of all patients were recovered to over 99% after administration of oxygen for three minutes in recovery room.

백서의 적출된 기도평활근에서 Ketamine의 이완효과

윤석화,김윤희,김상수,이상묵 충남대학교 의과대학 지역사회의학연구소 1997 충남의대잡지 Vol.24 No.2

The effects of anesthetics on airway smooth muscle tone are important in the management of patients with asthma. Airway epithelial cells and vascular endothelial cells modulate the tone of the underlying smooth muscle by releasing relaxing factors such as prostanoids and nitric oxide (NO). Ketamine, at concentrations achieved with the usual clinical doses, has a direct relaxant effect on airway smooth muscle. In the present study we evaluated whether the relaxant effect of ketamine depend on any of the epithelium-derived relaxing factors. Isolated rat tracheal preparations mounted in water-jacketed organ baths filled with modified Tris Tyrode buffer solution with 100% oxygen at 37˚C for recording isometric contractile force. In the first experimental step, Tracheae, in the absence and in the presence of epithelium, were contracted with acetylcholine(10^-8M-10^-3M), and we plotted concentration -response curve for the Ach. And then we examined the inhibitory effect of ketamine(10^-5 and 10^-4M) on the concentration-response curve for Ach. In the second experimental steps, we studied the effect of N-omega-nitro L-arginine methylester(L-NAME) on the relaxant activity of ketamine(10^-6-10^-3M) on trachea contracted by 10^-5M Ach. In the result, 1) Removal of the tracheal epithelium did not change the response to Ach. 2) 10^-5M ketamine not significantly changed, but 10^-4 M ketamine shifted to the right the concentration-response curves for Ach in both intact and denuded epithelium rings. 3) L-NAME did not influence the relaxant effect of ketamine on trachea contracted by 10^-5 M Ach. These results indicate that ketamine-induced tracheal smooth muscle relaxation is epithelium-independent and may be is mediated by inhibition of Ca^++ influx in nonspecific way.

윤상화,신윤석 龍仁大學校 武道硏究所 2003 武道硏究所誌 Vol.14 No.1

This study is attempted to survey the recognition of and desire for participation in Taegwondo for 920 students of 3 middle schools located in Myeonmok-dong of Seoul city as of 2003, to examine how they, our juveniles, recognize our proud Taegwondo and what they have desire for participation in Taegwondo, and to ultimately provide fundamental data for efficient Taegwondo education. Subjects of this study were selected randomly in 3 middle schools located in Myeonmokdong of Seoul City currently and totally 920 students from 1st year, 2nd year, and 3rd year students. Questionnaires were prepared on the basis of self-administration and, as a result of questionnaire, 10 questionnaires were excluded under the decision that they were not reliable and 910 valid samples were gained. For data analysis, SPSS 10.0 statistic program was applied and reliability analysis, frequency analysis, ANOVA, and pearson correlation were used as statistic analysis methods. Findings of this study from data analysis are as follows. First, it was shown that the recognition of middle school students for Taegwondo was high as a whole and, especially, the recognition of position and general recognition were significantly high. But, it was shown that they did not know well the cognitive area. Second, it was found that their desire for participation in Taegwondo was negative wholly while they showed high desire for participation with respect to psychomotor area and definitive area. Third, it was revealed that the higher their recognition of Taegwondo was, the higher their desire for participation in Taegwondo was.
