Spastic dysarthria is a motor speech disorder produced by a damage to the direct (pyramidal) and indirect (extrapyramidal) pathways of the central nervous system. This study attempted to determine the influences of the severity of spastic dysarthria on the stability of voice. A sustained /a/, /a/ produced at the beginning of a sentence and at the end of the sentence were analyzed. The Praat 4.0.51 was used for analysis. The results showed a significant difference between the severe spastic dysarthric group and normal group matched by age and sex at the beginning and the end of the sentence. In addition, the severe group showed a significant difference between the first /a/ and the second /a/ at the end of sentence.

The effect of remifentanil versus N_2O on postoperative pain and emergence agitation after pediatric tonsillectomy/adenoidectomy

Hey-Ran Choi,Jae Keun Cho,이상석,Byung Hoon Yoo,Jun Heum Yon,김계민 대한마취통증의학회 2011 Korean Journal of Anesthesiology Vol.61 No.2

Background: Remifentanil can be an alternative to N_2O in general anesthesia. Intraoperative remifentanil may lead to acute opioid tolerance. This study aims to assess the effect of remifentanil substituted for 70% N_2O on postoperative pain in children undergoing tonsillectomy/adenoidectomy. In addition, we evaluated the effect of remifentanil infusion on incidence of emergence agitation in these patients. Methods: Eighty children, aged 2-12 years, undergoing tonsillectomy/adenoidectomy were randomly allocated to the N_2O group (Group N; n = 40, sevoflurane and 70% N_2O) or remifentanil group (Group R; n = 40, sevoflurane with remifentanil infusion at the rate of 0.17 μg/kg/min). In the recovery room, severity of pain and agitation were assessed by an investigator blinded to the assigned group. Time to eye opening and incidence of severe pain and agitation were compared between groups. Logistic regression was used to identify factors related to occurrence of severe pain and agitation. Results: Number of patients with severe postoperative pain was 6 and 16 in groups N and R, respectively (P = 0.012). Incidence of emergence agitation was not significantly different between groups. Remifentanil infusion was a significant factor related to the occurrence of severe postoperative pain (P = 0.015), and age was inversely related to occurrence of emergence agitation (P = 0.001). Conclusions: In children undergoing tonsillectomy/adenoidectomy, intraoperative remifentanil infusion may increase incidence of severe postoperative pain compared to N_2O, but it may not affect incidence of emergence agitation.

A Study of Impact of Art on Successful Aging

Yong Ran Cho,Jeong Sik Cha,Hey Ryoen Kang 한국노인복지학회 2012 International Journal of Welfare for the Aged Vol.27 No.-

This study aimed to reveal impact of art and daily activities on the emotionality of the adults aged 60 or more. Results on the effects of physical activities on satisfaction show that art performance physical activities improve emotional wellbeing of old people, and therefore the subjects who perform those activities longer than two hours a week have highest level of satisfaction with wellbeing and medical services. Regarding social security benefit, certainly there is a linkage between the benefit and satisfaction; those without the benefit even has higher satisfaction with welfare satisfaction, indicating that lower socioeconomic status has negative impacts on satisfaction even though they receive welfare benefits. First, we looked at the agel general welfare center employees` work stress, public support, and depression level. The major cause of work stress was excess amount of labor by 3.291 points, followed by work complications with 3.207 points and workers` identity crisis by 2.291 points. Looking at the public support level, it had an average of 3.65 points, which is higher than average(median). The depression level had an average of 2.22points, which is lower than the average(median). Therefore, agel general welfare center employees` state of depression is fairly low.

Chronic Subdural Hematoma after Eccentric Exercise Using a Vibrating Belt Machine

Park, Hey-Ran,Lee, Kyeong-Seok,Bae, Hack-Gun The Korean Neurosurgical Society 2013 Journal of Korean neurosurgical society Vol.54 No.3

We report a case of bilateral chronic subdural hematoma (CSDH) in a 75-year-old man after exercise using a vibrating belt machine on the head. He suffered from headache and intermittent left side numbness for ten days. He denied any head injuries except eccentric exercise using a vibrating belt on his own head for 20 days. An MRI revealed bilateral CSDH. The hematoma was isodense on the CT scan. We made burr-holes on the both sides under local anesthesia. We identified the neomembrane and dark red subdural fluid on both sides. In the postoperative CT scan, we found an arachnoid cyst on the left temporal pole. Although the arachnoid cyst itself is asymptomatic, trivial injury such as vibrating the head may cause a CSDH.

학교조직풍토와 교수몰입 간의 관계에서 교수효능감의 매개효과

이혜란(Hey Ran Lee),김아영(Ah Young Kim),차정은(Jung Eun Cha) 한국교육심리학회 2011 敎育心理硏究 Vol.25 No.3

이 연구의 목적은 교사가 지각하는 학교조직풍토, 교수효능감과 교수몰입 간에 어떠한 관계가 있는지 탐색한 후, 교수몰입에 대한 학교조직풍토의 영향을 교수효능감이 매개하는가를 구조모형을 통해 검증하는 것이다. 이를 위해 수도권 소재 초, 중, 고등학교에 재직 중인 교사들을 대상으로 실시한 설문자료 총 674부를 분석하였다. 분석결과, 학교조직풍토 하위요인 중에서 교사의 친교적 행동과 헌신적 행동, 그리고 교장의 인간지향적 행동과 목표지향적 행동과 같은 긍정적인 행동들은 교수효능감 및 교수몰입과 정적인 상관을 보이고, 교사의 방관적 행동과 교장의 관료지향적인 행동은 교수효능감 및 교수몰입과 높지는 않지만 부적인 관련성을 보이는 경향이 나타났다. 구조모형에 대한 분석결과에서는 교사의 헌신적 행동과 인간지향적 행동의 영향이 교수효능감을 통해서 교수몰입에 영향을 주는 경로가 유의한 것으로 나타나 학교조직풍토의 영향을 교수효능감이 매개하는 것을 확인하였다. 또한 교수효능감은 교수몰입에 대해 강력한 영향력을 행사하는 변인임이 확인되었다. 연구결과를 교육현장에 대한 시사점을 중심으로 논의하였다. The purpose of this study was to examine the relationships among organizational climate of schools, teaching efficacy, and teaching flow, and to confirm the mediating effect of teaching efficacy in the relationship between organizational climate and teaching flow using covariance structural equation modeling analysis. To accomplish the purpose, we have gathered responses of self-reported questionnaires assessing organizational climate of schools, teaching efficacy, and teaching flow from 682 teachers in 34 elementary, middle, and high schools around Seoul and the metropolitan area. The results revealed that there was positive correlation between teaching efficacy and teaching flow. Among the sub-factors in the school climate scale, positive sub-factors such as teachers` intimate and dedicated behaviors, and principals` people-oriented behaviors and goal-oriented behaviors were positively correlated with teaching efficacy and teaching flow, whereas negative sub-factors such as teachers` negligent behaviors and principals` bureaucratic behaviors were negatively correlated with teaching efficacy and teaching flow. However, the structural analysis results revealed that the effects of the teachers` intimate and dedicated behaviors on the teaching flow were mediated by the teaching efficacy. Results were discussed in relations to the educational practice in Korea.

Effects of hydrocortisone-presensitized sugammadex on recovery from neuromuscular blockade induced by rocuronium: a rodent in vivo study

Choi Hey-Ran,Yang Hong Seuk,Choi Jae-Moon,Park Chungon,인준용,김용범 대한마취통증의학회 2022 Anesthesia and pain medicine Vol.17 No.2

Background: Sugammadex is a specific antagonist of aminosteroidal neuromuscular blocking agents with 1:1 binding to guest molecules. Sugammadex can also bind to other drugs having a steroid component in its chemical structure. In this in vivo experiment, we investigated the differences in the recovery of rocuronium-induced neuromuscular blockade using sugammadex pre-exposed with two different concentrations of hydrocortisone.Methods: The sciatic nerves and tibialis anterior muscles of 30 adult Sprague–Dawley rats were prepared for the experiment. The sciatic nerves were stimulated using a train-of-four (TOF) pattern with indirect supramaximal stimulation at 20 s intervals. After 15 min of stabilization, a 250 μg loading dose and 125 μg booster doses of rocuronium were serially administered until > 95% depression of the first twitch tension of TOF stimulation (T1) was confirmed. The study drugs were prepared by mixing sugamadex with the same volume of three different stock solutions (0.9% normal saline, 10 mg/ml hydrocortisone, and 100 mg/ml hydrocortisone). The recovery of rats from neuromuscular blockade was monitored by assessing T1 and the TOF ratio (TOFR) simultaneously until T1 was recovered to > 95% and TOFR to > 0.9.Results: In the group injected with sugammadex premixed with a high concentration of hydrocortisone, statistically significant intergroup differences were observed in the recovery progression of T1 and TOFR (P < 0.050).Conclusions: When sugammadex was pre-exposed to a high dose of hydrocortisone only, recovery from neuromuscular blockade was delayed. Delayed recovery from neuromuscular blockade is not always plausible when sugammadex is pre-exposed to steroidal drugs.

박혜란 ( Hey Ran Park ),유승석 ( Seung Seok Yoo ) 한국식품조리과학회(구 한국조리과학회) 2012 한국식품조리과학회지 Vol.28 No.3

In this study, the preparation characteristics of cream cheese added mousse cake which can easily be accessible among the mousse cakes, have drawn a lot of attention from the modern people, However, there have been a lack of studies that focused on the manufacturing of the mousse cake with a various added proportion rates of main ingredients, fresh cream in mousse cake by 0%, 25%, 35%, 45%, and 55%. While the sugar concentration has increased, except for the control group, there is no significant difference. In case of chromaticity, it has shown high level at L values. In addition, values have shown bigger values as increasing the added amount, and b values have shown smaller values as increasing the added amount. For moisture content, it has shown as steadily increasing by heightening the added amount of cream cheese. For texture, CM3 added by 35% in all the items, except for hardness, has shown the best result and CM3 added by all 35% in all the items, has also been evaluated as highest. Based on all the results, it can be concluded that the addition of cream cheese by 35% to fresh cream is most appropriate, on manufacturing the cream cheese mousse cake.
