Prolonged neuromuscular blockade following succinylcholine may be seen when anticho- linesterase had been administered prior to reverse nondepolarizing muscle relaxant-induced paralysis, possibly anticholinesterase has been reported to inhibit serum cholinesterase activity. Our study was undertaken in order to understand the effect of a nondepolarizing muscle relaxant (vecuronium) following neostigmine pretreatment. In this study, we assessed the effect of vecuronium induced neuromuscular blockade using a train of four, 2 Hz stimulations on ulnar nerve. Patients admitted to our hospital for elective operations were divided into two groups, each group consisting of 16 patients. In group I, vecuronium 0.1 mg/kg was .administered according to the priming principle following normal saline, in group II, vecuronium 1.0mg/kg was administered according to the priming principle following neostigmine 0.05 mg/kg and glycopyrrolate 0.003 mg/kg pretreatment. Then the time for Tl to reach 5% or less(second), and the time for Tl to reach from 25% to 75%(recovery index) were measured in both groups. The time for Tl to reach 5% or less in group I(92.8±14.72 second) and group II(97.5±16.43 seconds) were not siginificant. However the recovery indexof group I(10.2 5±1.93 minute) and group II(8.5±1.80 minute) showed significant shortening in group II(p$lt;0. 05)

The purpose of this study was to analyze visitors' recognition of the Arboretum's brand assets. To achieve the purpose of the study, the empirical analysis was conducted on Herb Farm in Wonju and discussed the implications of the study. The analysis results showed that loyalty, image and recognition were derived as components of brand assets, and overall, visitors' perception of brand assets was good. However, it suggested the need to introduce effective promotional marketing tools such as social media and online for recognition factors that have been analyzed relatively low levels of visitor awareness. In addition, we discussed the introduction of additional programs such as experience and commentary in order to improve the level of awareness of loyalty. On the other hand, as a result of analyzing the influence of brand asset composition factors on visitor satisfaction, all factors showed a positive effect on satisfaction. In particular, the analysis suggests that more detailed consideration is required for loyalty, which has a higher impact on visitor satisfaction than other factors. 본 연구는 수목원의 브랜드 자산에 대한 방문객의 인식을 분석하는데 목적을 두고 수행되었다. 연구목적 달성을 위해 원주시 허브팜을 대상으로 실증분석을 실시하였으며, 분석결과를 바탕으로 연구의 시사점에 대해 논의하였다. 분석결과, 브랜드 자산 구성요인으로 충성도, 이미지, 인지도가 도출되었으며, 전체적으로 방문객의 브랜드 자산에 대한 인식은 긍정적인 것으로 분석되었다. 하지만 방문객 인식도가 상대적으로 낮게 분석된 인지도 요인에 대해서는 소셜미디어, 온라인 등 효과적인 홍보마케팅 수단 도입의 필요성을 제시하였다. 또한, 충성도에 대한 인식수준 향상을 위해 체험 및 해설 등의 추가적인 프로그램 도입에 대해 논의하였다. 한편, 브랜드 자산 구성요인이 방문객 만족도에 미치는 영향에 대한 분석결과, 모든 요인이 만족도에 긍정적인 영향을 미치는 것으로 나타났다. 특히, 분석결과는 다른 요인에 비해 방문객 만족도에 높은 영향을 미치고 있는 충성도에 대해 보다 세밀한 고려가 필요함을 시사하였다.

술후 통증 평가 : 시각 아날로그 척도에 대한 안면 등급 척도의 비교 Facial Rating Scale Compared with Visual Analogue Scale

최영석,이미경,김성배,이일옥,임상호,김난숙,공명훈 대한마취과학회 2000 Korean Journal of Anesthesiology Vol.39 No.5

Background : Although visual analogue scale (VAS) is a good self-assessment method for postoperative pain, faces pain scale (FPS) may be also used as objective assessment method in patients with unavailable of VAS. We investigated the usefulness of facial rating scale (FRS), the variants of VAS and FPS, compared with VAS in postoperative adult patients. Methods : One hundred and six, ASA 1 or 2, patients undergoing elective surgery under general anesthesia were educated VAS (10 cm) and FRS. One hour after operation, patients self-reported VAS and FRS were measured in the recovery room. The scores were analyzed by Spearman's correlation and Intraclass correlation. Results : Correlations indicated a highly significant relationship between VAS and FRS (Spearman's correlation coefficient = 0.84, Intraclass correlation coefficient = 0.92, both of P $lt; 0.01). Conclusions: FRS may be useful for self-reported pain assessment instead of VAS in postoperative adult patients. (Korean J Anesthesiol 2000; 39: 696-699)

최근 ASEAN 국가들의 서비스무역 결정요인에 대한 연구 - 재화무역과의 비교를 통한 동태적 분석을 중심으로 -

최영석 한국외국어대학교 동남아연구소 2022 東南亞硏究 Vol.32 No.2

Trade in services and trade in goods generally increase as the GDP of a trading partner increases. However, trade-increasing effect of GDP is generally smaller in services trade than in goods trade. The effect of GDP per capita is relatively smaller compared to the case of GDP. Distance is inversely related to trade in services and goods. However, services are less affected by distance than goods. If the trading partner is an ASEAN country, it has the effect of increasing trade. Even if the trading partner is an East Asian country, there is usually a trade increase effect, but there is also a large variation between countries. Looking at the changes in the determinants, the overall GDP effect and the ASEAN effect increased. In particular, the ASEAN effect is showing a rapidly increasing trend. On the other hand, the effect of the distance variable had a decreasing change. However, the changes in the per capita GDP effect and the East Asian effect are varied. 이 연구는 ASEAN 주요 6개 국가들의 서비스무역 결정요인과 최근 10년 사이의 변화를 재화무역의 경우와 대비하며 여러 논점에 대해 중력모형을 사용하여 비교분석을 하였다. 그 결과 발견한 점들은 다음과 같다. 먼저 무역상대국의 GDP가 클수록 서비스와 재화의 무역은 일반적으로 증가한다. 그런데 이 GDP의 무역증대 효과는 일반적으로 서비스무역이 재화무역보다 작다. 일인당 GDP의 효과는 GDP의 경우와 비교하면 상대적으로 작다. 거리는 서비스나 재화의 무역과 반비례관계가 있다. 그런데 서비스가 재화보다 거리의 영향을 상대적으로 작게 받는다. 무역상대국이 ASEAN 국가일 경우 무역을 증대하는 효과가 있다. 무역상대국이 동아시아 국가일 경우도 대체로 무역증대 효과가 있는데 역시 국가 간 편차가 크게 나타난다. 결정요인 변화를 볼 때 전반적으로 GDP효과와 ASEAN효과는 증가하였다. 특히 ASEAN효과는 급증하는 경향을 보이고 있다. 반면, 거리변수의 효과는 감소하는 변화를 하였다. 그러나 일인당 GDP효과와 동아시아효과의 변화는 다양하게 나타나고 있다.

최영석,이미경,윤석민,임상호,공명훈,정유성 대한마취과학회 1998 Korean Journal of Anesthesiology Vol.35 No.5

Background : Desflurane, a fluorinated methyl-ethyl ether, has some advantageous properties including low blood solubility, stability in soda lime, and resistance to biodegradation. Desflurane in vivo has demonstrated myocardial depressant property. The purpose of this study was to test the direct effects of desflurane on myocardial contractile function and coronary flow in the isolated heart. Methods : Twelve isolated rat hearts were continuously perfused with modified Krebs solution containing 6, 9 and 12 vol% of desflurane for 10 min at each concentration. Systolic left ventricular pressure and rate of change of ventricular pressure (dp/dt) were measured. Heart rate and coronary flow were also measured. To differentiate direct vasodilatory effect of desflurane from an indirect metabolic effect due to autoregulation of coronary flow, oxygen delivery, myocardial oxygen consumption and percent oxygen extraction were calculated. Results : Heart rate (control 266 22 beats/min) decreased to 250 23 beats/min at 6 vol%, 236 26 beats/min at 9 vol% and 223 22 beats/min at 12 vol% of desflurane. Systolic left ventricular pressure and dp/dt decreased in a concentration-dependent manner. In spite of decrement of myocardial oxygen consumption, coronary flow (control 12.0 1.2 ml/min) increased to 12.8 1.6 ml/min at 6 vol%, 12.9 1.6 ml/min at 9 vol% and 13.7 1.4 ml/min at 12 vol% of desflurane. Oxygen delivery increased proportionally with coronary flow. Percent oxygen extraction decreased in a concentration-dependent manner. Conclusion : These results suggest that desflurane has a direct myocardial depressing and coronary vasodilating effect in a concentration-dependent manner. (Korean J Anesthesiol 1998; 35: 825∼830)

Laryngeal Mask 를 이용한 전신마취시 수술후 인후통에 대한 관찰

최영석,이일옥,윤석민,임상호,김난숙,김종욱 대한마취과학회 1991 Korean Journal of Anesthesiology Vol.24 No.5

The laryngeal mask as an new form of airway has recently been described. This mask is introduced blindly into the hypopharynx to form a seal around the larynx, so permitting spontaneous or positive pressure ventilation without passing the larynx, therefore associated with much reduced incidence of laryngeal damage. But endotracheal intubation is associated with a significant rate of layngeal damage and subsequent vocal cord pathology. This study was designed to investigate the effects of postoperative sore throat related to insertion of laryngeal mask airway and to compare with these effects after endotracheal intubation. One hundred randomly selected female patients who had gynecological procedures under general anesthesia were surveyed to ascertain the incidence of sore throats. The results were as follows; 1) The incidence of sore throat after endotracheal intubation with the Portex tube was 48% but 12% after insertion of laryngeal mask. 2) The average volume of air required to inflate the cuff of laryngeal mask sufficiently to form air-tight seal around larynx was 11.4±2.8ml and cuff pressure was 25.6±13.2cmH2O when the laryngeal mask 3 was used for Korean adult female.

신속 삽관법을 통한 마취유도시 안압의 증가를 억제하는 Propofol 적정 용량

최영석,류태간 대한마취과학회 2001 Korean Journal of Anesthesiology Vol.40 No.1

3384010102-3 Background: Operations for patients with eye injuries frequently require rapid sequence induction of general anesthesia with succinylcholine (Sch), but Sch as well as endotracheal intubation produce increases in intraocular pressure (lOP). The purpose of this study was to examine whether the increase in dosage of propofol from a usual dosage would prevent the increase in IOP due to endotracheal intubation with Sch during a rapid sequence induction of general anesthesia. Methods: Changes in lOP were measured in three groups of 15 patients each. The patients randomly received thiopental 5 mg/kg (group 1, n = 15), propofol 2.5 mg/kg (group 2, n = 15) or propofol 3.0 mg/kg (group 3, n = 15), followed by Sch 1.0 mg/kg and endotracheal intubation. IOP, systolic arterial pressure (SAP) and heart rate (HR) were measured before induction (baseline), Just after intubation, 3 minutes and 10 minutes after intubation. Results: IOP and SAP just after intubation in groups 1 and 2 increased significantly from baseline. but did not increase significantly from baseline in group 3. IOP and SAP at 3 minutes after intubation in group 1 did not decrease significantly from baseline, but decreased significantly from baseline in groups 2 and 3. IOP and SAP at 10 minutes after intubaton in all groups decreased significantly from baseline. HR just after intubaton in groups 1 and 2 increased significantly from baseline but did not increase significantly from baseline in group 3. HR at 3 minutes and 10 minutes after intubation in all groups did not change significantly from baseline. Conclusions: The authors concluded that propofol 3.0 mg/kg could prevent the increase in IOP, systolic arterial pressure and heart rate just after intubation during a rapid sequence induction of general anesthesia.
