Background: Continuous interscalene block has been known to improve postoperative analgesia after arthroscopic shoulder surgery. This was a prospective study investigating the ultrasound-guided posterior approach for placement of an interscalene catheter, clinical efficacy and complications after placement of the catheter. Methods: Forty-two patients undergoing elective arthroscopic shoulder surgery were included in this study and an interscalene catheter was inserted under the guidance of ultrasound with posterior approach. With the inplane approach, the 17 G Tuohy needle was advanced until the tip was placed between the C5 and C6 nerve roots. After a bolus injection of 20 ml of 0.2% ropivacaine, a catheter was threaded and secured. A continuous infusion of ropivacaine 0.2% 4 ml/hr with patient- controlled 5 ml boluses every hour was used over 2 days. Difficulties in placement of the catheter, clinical efficacy of analgesia and complications were recorded. All patients were monitored for 48 hours and examined by the surgeon for complications within 2 weeks of hospital discharge. Results: Easy placement of the catheter was achieved in 100% of the patients and the success rate of catheter placement during the 48 hr period was 92.9%. Postoperative analgesia was effective in 88.1% of the patients in the post anesthetic care unit. The major complications included nausea (7.1%), vomiting (4.8%), dyspnea (4.8%) and unintended vascular punctures (2.4%). Other complications such as neurologic deficits and local infection around the puncture site did not occur. Conclusions: The ultrasound-guided interscalene block with a posterior approach is associated with a success high rate in placement of the interscalene catheter and a low rate of complications. However, the small sample size limits us to draw definite conclusions. Therefore, a well-designed randomized controlled trial is required to confirm our preliminary study.

Background: Dexmedetomidine is an α2-adrenoreceptor agonist with sedative, analgesic and anxiolytic effects, and it has more selective α2-adrenergic effect than clonidine. We evaluate the effect of preansethetic dexmedetomidine 1 μg/kg single infusion on sedation, hemodynamics, anesthetic consumption, and recovery profiles during anesthesia. Methods: Forty-two female patients with American Society of Anesthesiologists physical status I or II undergoing gynecologic surgery with anticipated operation time of 2 h, were randomly assigned to receive dexmedetomidine 1 μg/kg (Dex group) or saline (control group) iv over 10 min before anesthetic induction. After tracheal intubation with propofol 2 mg/kg, cisatracurium 0.15 mg/kg iv, anesthesia was maintained with sevoflurane, O2 50%, N2O 50% around a BIS value of 40. Results: After study drug infusion, BIS of Dex group was lower than that of control group (93.9 ± 3.1 vs 51.5 ± 5.2, P < 0.05). Mean arterial pressure (MAP) and heart rate (HR) after intubation were increased in control group, but did not change in Dex group. During maintenance, there was no difference in MAP between groups, but HR of Dex group was lower compared to that of control group. End-tidal concentration (2.0 ± 0.5 vol% vs 1.4 ± 0.3 vol%, P < 0.05) and total cumulative consumption of sevoflurane (34.6 ± 3.8 ml vs 26.5 ± 5.3 ml, P < 0.05) were lower in Dex group than in control group. Recovery profiles, modified Aldrete score, postoperative nausea vomiting, and visual analogue pain score were not significantly different between groups. Conclusions: Preanesthetic dexmetomidine 1 μg/kg single infusion is a simple, easy, and economic general anesthetic adjuvant that maintains stable hemodynamics and decrease anesthetic consumption without the change of recovery profiles.

This paper investigates the effects of online private lectures and EBS lectures on the Scores of the Social Studies Inquiry Subject of the College Scholastic Ability Test (CSAT) using the 4th and 5th year Korea Education and Employment Panel that conveys some questionnaires regarding the CSAT. We used a method of two-stage least squares considering the endogeneity problem among variables and derived the following implications. First, the scores of the Social Studies Inquiry Subject are higher among the students who have an experience of private education. However, we could not find such results when we excluded students who did not study the subject after school. This result implies that private education is not necessarily superior to after-school studies in terms of public education when attempting to raise CSAT scores. Second, online private lectures do not yield statistically significant effects on CSAT scores compared to EBS lectures when we look into the group of students who took either online private lectures or EBS lectures. This result implies that the government policy that intends to relate the CSAT with EBS lectures might be effective in reducing households` economic burden for private lessons at least in the Social Studies Inquiry Subject.

대학 입시 전형 요소가 사교육에 미치는 영향

신혜원 ( Hye Won Shin ),장경호 ( Kyung Ho Jang ) 한국사회과교육학회 2013 시민교육연구 Vol.45 No.1

본 연구에서는 A대학 신입생을 대상으로 실시한 사교육 조사 결과를 이용하여 대학 입시전형 요소가 사교육에 미치는 영향을 분석하였다. 분석 결과, 대학 입시 전형 요소로 논술이사교육에 미치는 영향이 가장 큰 것으로 나타났다. 이는 논술이 다수의 대학에서 요구하는 전형 요소임에도 불구하고 고등학교에서의 체계적인 교육 방침이 없고, 대학에서도 이러한 고등학교의 상황을 고려하지 않은 채 주요 전형의 하나로 내세우고 있기 때문인 것으로 풀이된다. 사교육의 의존도를 낮추고 공교육 활성화를 통해 민주 시민 교육의 토대를 구축하기 위해서는 대학 입시 전형을 개선할 필요가 있는 것으로 보인다. This paper investigates the effects of university admission process on private education using the survey data for the freshmen who got into a university located in the metropolitan area in 2011. We use a logit analysis to find that essay tests have the greatest effect on the students` experiences on private education for the entrance examinations they prepared. We conjecture that the gap between the universities` requirement and the students` ability measured by the essay tests yields high demand for private education for the tests. This result raises the necessity to reform university admission process to make foundations of social studies education through lowering dependence on private education as well as cultivating school education.

『지킬 박사와 하이드 씨』의 고딕 소설적 특징과 각색 공연물과의 비교

This essay examines Robert Louis Stevenson’s novella, The Strange Case of Dr Jekyll and Mr Hyde, in comparison with its theatrical adaptations. As a gothic fiction written in the fin-de-siècle Victorian age, Dr Jekyll and Mr Hyde demonstrates the central themes of nineteenth-century gothic literature, featuring the ambiguity of human nature, doubt regarding science and rationalism, and middle-class hypocrisy and guilt, all of which are embodied by the novella’s protagonist, Jekyll. In contrast to these predominantly gothic conventions seen in the fiction, its theatrical and musical adaptations add the key features of melodrama to the original story. Instead of Jekyll’s moral ambiguity and psychological conflict, the stark contrast between Jekyll and Hyde, each incarnating human goodness and malice, symbolizes the indelible separation between good and evil. As the plot has become simplified, a new element of heterosexual romance has also been inserted in Thomas Sullivan’s play and Frank Wildhorn’s musical. These melodramatic features effectively bring out the audience’s (excessive) emotion. Dr Jekyll and Mr Hyde and its theatrical adaptations showcase how a literary classic, turning into a new text using different mediums, can be reread and reinterpreted by the readers and audience. This protean performativity of the text contributes to the novella’s undying popularity.

코맥 매카시의『핏빛 자오선』

신혜원(Hyewon Shin) 한국아메리카학회 2022 美國學論集 Vol.54 No.1

Blood Meridian is an intriguing text exhibiting Cormac McCarthy’s appropriation of the Western genre. The classical Western depicts the confrontations between two contending forces—the East and the West, white settlers and native Americans, and civilization and wilderness—at the backdrop of the Wild West. On the other hand, the revisionist Western of the 1960s and the 1970s casts light on the unknown histories of the victims of violent suppression and genocide during the era of American imperial wars of the nineteenth century. Blood Meridian reveals the limits of both the classical Western and the revisionist Western with regards to characters, setting and theme. Set in the frontier, as the backdrop of the American myth of the West and Manifest Destiny, the novel severely criticizes American capitalism and imperialism, describing the Glanton gang’s merciless murders. It also blurs the boundaries between civilization and barbarism through its central character, Judge Holden, who incarnates universal evil and mindless violence. While Holden’s book represents knowledge and art that kills life through its aesthetic objectification, McCarthy’s novel ironically grants Holden an eternal life as a fictional character. Insinuating the intricate relations between violence and art, McCarthy demonstrates that art, including writing, creates life and thus makes redemption and regeneration possible.
