Bernardo Aguilera-Bohórquez,Mauricio Pachón,Miguel Sánchez,Orlando Ramos-Cardozo,Erika Cantor 대한정형외과학회 2019 Clinics in Orthopedic Surgery Vol.11 No.4

Background: To compare the hemodynamic parameters—electrolyte concentration, D-dimer level, creatine phosphokinase level—and the incidence of early complications of simultaneous bilateral versus unilateral hip arthroscopy. Methods: A prospective study was conducted on patients (> 18 years of age) undergoing unilateral or bilateral hip arthroscopy under the same anesthetic between 2013 and 2015. Patients were followed up for 30 days after surgery. In all cases, data were collected before, during, and after the surgical procedure. Results: One hundred cases of hip arthroscopy (51 unilateral and 49 bilateral) were included in this study. There was a greater variation in systolic blood pressure and heart rate in the unilateral group. The sodium levels were higher in the bilateral group with an adjusted mean difference of 5.31 mmol/L (p < 0.001). During the first 24 hours after the procedure, the proportion of patients with an altered D-dimer of > 500 ng/mL was 85.7% in the bilateral group and 56.9% in the unilateral group. There was no significant difference in the incidence of complications between the groups (bilateral, 8.2%; unilateral, 9.8%; crude odds ratio, 0.83; 95% confidence interval, 0.24 to 2.92; p = 0.526). Conclusions: The variations of hemodynamic parameters in patients undergoing hip arthroscopy remained within normal ranges. The findings of this study suggest that bilateral hip arthroscopy be selected according to the patient’s condition, considering that the risk of complications and metabolic alterations in bilateral hip arthroplasty are similar to those in unilateral arthroscopy.

Relationship between Spinopelvic Parameters and Hip Function in Patients with Femoroacetabular Impingement at Diagnosis: A Cross-Sectional Study

Bernardo Aguilera-Bohórquez,Pablo Corea,Cristina Sigüenza,Jochen Gerstner-Saucedo,Alvaro Carvajal,Erika Cantor 대한고관절학회 2023 Hip and Pelvis Vol.35 No.1

Purpose: The aim of this study was to determine correlation between the spinopelvic parameters in sitting and standing positions (sacral slope [SS], lumbar lordosis [LL], spinopelvic tilt [SPT], pelvic incidence [PI], and pelvic femoral angle [PFA]), with hip function assessed using the modified Harris hip scores (mHHs) in patients with symptomatic femoroacetabular impingement (FAI) at diagnosis. Materials and Methods: A retrospective study of 52 patients diagnosed with symptomatic FAI was conducted. Evaluation of the spinopelvic complex in terms of SS, LL, SPT, PI and PFA was performed using lateral radiographs of the pelvis and lumbosacral spine in standing and sitting positions. Assessment of hip function at diagnosis was performed using the mHHs. Calculation of spinopelvic mobility was based on the difference (Δ) between measurements performed in standing and sitting position. Results: The median time of pain evolution was 11 months (interquartile range [IQR], 5-24 months) with a median mHHs of 66.0 points (IQR, 46.0-73.0) at diagnosis. The mean change of LL, SS, SPT, and PFA was 20.9±11.2。, 14.2±8.6。, 15.5±9.0。, and 70.7±9.5。, respectively. No statistically significant correlation was observed between spinopelvic parameters and the mHHs (P>0.05). Conclusion: Radiological parameters of the spinopelvic complex did not show correlation with hip function at the time of diagnosis in patients with symptomatic FAI. Conduct of further studies will be required in the effort to understand the effect of the spinopelvic complex and its compensatory mechanics, primarily between the hip and spine, in patients with FAI before and after hip arthroscopy.

Nietzsche의 Dionysos的 世界觀

金保謙 제주대학 1981 논문집 Vol.13 No.1

"Wissenschaft, Kunst und Philolophie wachsen jetzt so sehr in mir zusammen, das ich jedenfalls einmal Centauren gera¨ren werde", schreibt Nietzsche Ende Januar 1870. In seinem Fru¨hwerk " Die Geburt der Tragodie" offenbart sich schon eigentlich der ganze Nietzsche, der in bezug auch auf das Historische, auf ein zeitlich begrenztes, unr in sich gultiges geschichtliches Thema ganz und gar kontrapunktisch dachte (Betrachtung des Griechentums unter der Formel "apollinisch=dionysisch"), der Kulturen physiognomisch zu nehmen wusste. Netzsche war Romantiker, der letzte Romantiker, der sich eben deshalb nach Kultur nur schnen konnte, die er um sich herum bereits vermiβte. Nietzsche war auf der anderen Seite wiederum kein Systematiker, kein Vertreter analytisch=kritischer Wissenschaftsmethodik; er hat uns auch in dieser Beziehung neue fruchtbarer bzw. zeitgemaBere Wege gewiesen, Wege, die uns vom alten Wissenschsftsideal immermehr entfernt. Ob wir es zugeben oder nichet, ob wir es wollen oder nicht, wkr sind heute alle, was die Relativierung von Werten und Idealen jeglicher Art bzw, was deren Verzeitlichung betrifft, die Schuler Nietzsches, dessen Ideal schlieβlich die Ideallosigkeit gewesen ist(denn alle "Ideale" werden ja in dieser Philosophie zuletzt zu Krucken fu¨r die Schwachen), der-unter dem Aspekt des Willens zur Macht-zum groβen Moralerneuerer insofern wured, als er den Nachweis zweier von jeher nebeneinader bestehender Moralen erstmalig zu fuhren wagte, den Nachweis einer Herrenmoral und einer Sklavenmoral und damit den Nachweis von der Zektbedingtheit und Abha¨ngigkeit vom menschlichen Wesen, von Blut, Herkunft, Rasse des Individuums, auch aller morlischen Werte Der Wert des Wirklichkeitsformen, die das Leben jeweis annimmt, richtet sich in keiner Hinsicht nach "ewigenGestzen", sondern einzig und allein nach dem Intensitatggrade des dahinterstehenden W I l l e n s z u M a c h t. Nietzsches Fragment gebliebenes Hauptwerk des "Willens zur Macht", das die wesentlichen Probleme des 19. Jahrhunderts im Sinne des 20. Jahrhundert sieht und beantwortet, enthalt bereits alle Aufgaben der na¨chsten hundert Jahre.

My purpose in studing this research is to improve upon a lecture method in university. I referred to sundry and antecedent records, questionnairing and merits of them, as a means of this research. The results of this reserch can be classified into 5classes: 1. University professors including university authories should be cognizant of the importance of the lecture programs. 2. University professors should initiatively prepare and make the most of the lecture programs for students to heighten the effectiveness of lecturing. 3. University professors should take much interest in the inducement of students studying motivation in class. 4. University professors should utilize mutually both catechism and audio-visual method. 5. University professors should go their classes, keeping the necessary conditions of better lecturing manner.

學校行政에서 指導性狀況理論에 關한 硏究

The aim of this study is to review the trends in approaches to the relationship between leadership and perceptual modes and thereby to construct a situational leadership theory in school administration based on Paul Hersey and Kenneth H. Blanchard's situational leadership theory and A.W. Combs' list of successful teacher's modes of perception. The situational leadership theory to be applied in school administration has been constructed through four types of leadership, that is, (1) high task and low relationship, (2) high task and high relationship (3) low task and high relationship, and (4) low task and low relationship, their effectiveness dimension, and the successful scale of teacher's perceptual modes. The task of school administration will become a more complex one in the repidly changing society and a satisfactory financial investment is hardly expected. So it is urgent that a program schould be sought for teacher's contribution to the school administration system for a more effective school management. The school administrator's reponsibility is, therefore, to develop and increase the teacher's capacity of contribution. The situational leadership theory presented here to be applied in school is one of such devices. In addition, a related leadership theory and perception theory have been summarized for the same purpose. But the problem of school administrator's leadership awaits a further study and development.

陳保永 서울市立大學校 1983 論文集 Vol.17 No.-

This study aims at developing an instructional method to fulfill the ever-changing college education. For this purpose, an integrated approach was adopted through analyzing methods practised in the present college education, suggesting a way to improve them by group discussion, and introducing the newly developed teaching method. For a better instruction, the following are suggested! Firstly, a better educational outcome could be achieved by using a syllubus fixed as essential educational data. Secondly in the lecture method, various techniques such as motivation, questioning, discussing, and audio-visual aids could lead to a better educational effect. Thirdly in the problem-solving method, the frequency, time, amount, and the school record of assignments could be used along with a teaching assistant and the curriculum library for the same purpose. Finally in team teaching, an effective teaching-learning could be possible by constructing a cooperative organization of professors and students.

여성 아나운서의 메이크업 스타일 변화에 관한연구 : 1990년대와 2000년대를 비교중심으로

The following paper cross-examines the change and reason in the announcer's makeup styles following the change in broadcasting programs. The announcers of the 90's were more of an information carrier as an announcer and a broadcaster than a female, and hence their makeup was restricted to express reliability and professionalism. However, as the role of female announcers became more diverse with program changes and as they became more involved in programs other than news, their makeup styles changed and became more diverse. The announcers of the 21st century are involved in many areas of activities and roles as to be called 'annatainers'. The demand for broadcasters is increasing to meet the need for diversity, and this in turn calls for diverse talent on the part of the announcer, not just on celebrities. Starting with this paper, there should be consistent research on announcers and female broadcasters in diverse fields and changes in their makeup styles following changes in fashion and trend.

Nietzsche 哲學의 現代的 照明

金保謙 제주대학교 1984 논문집 Vol.22 No.2

황혼이 짙어갈 무렵 오지리 Wien의 Karlenberg 언덕에서 시가를 내려다 볼 때 모든 걸물이나 많은 사원들의 뾰죽한 탑들이 어둠에 잠기어 버리는데, 오직 성 Stephan사원^1)의 탑만이 점점 높이 솟아오름을 볼 수가 있다. 마치 이와도 같이 시간과 공간의 거리를 달리하면 할수록 그의 위대성이 부각되는 고독한 Nietzsche - 다시에는 사회각층으로부터 냉대와 멸시를 받은- 의 철학을 여기 현대적인 각도로서 그 의의를 재조명해 보고자 하지만, 그 근원이 희미한 어둠속에 잠겨 있는 이상 Nietzsche 철학의 탐색의 여로는 그다지 용이한 것은 아닐 것이다. 위기와 동란의 세기라고 일컬어지는 더욱 원폭의 위협, 세계각지에서의 끊일줄 모르는 처참한 무력항쟁등, 그 어느 것을 보더라도 현대의 문명사회의 병근이 깊어만가는 느낌이 든다.
