E. R. JANG, Y. H. PARK, C. H. YOUM, K. W. SEO, S. J. NOH. Study of the forearm EMG activities during Kumdo head striking. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 219-233, 2004. The purpose of this study was to compare the EMG activities of four-forearm muscles during Kumdo head striking. The four skilled and unskilled Kumdo club members were selected from D university in B city. Investigated muscles were left brachioradialis, right brachioradialis and left flexor carpi radialis, right flexor carpi radialis. Raw EMG data were collected during the head striking motions and the average EMG were calculated by the frame width of 0.05s, and then the average %MVC were calculated. The average %MVC values of each muscle in each group were compared. The results are as follows. 1) In each group, there were no significant statistical differences between every muscle over the all phases. 2) There were significant differences, however, between skilled group and unskilled group. The former got higher average %MVC at left flexor carpi radialis and the latter at right brachioradialis in the ready phase and in the impact phase.

The purpose of this study was to investigate how preceptor experience has an effect upon preceptor nurses. This study was so designed that it could compare the difference between clinical performance and Job satisfaction of preceptor nurses and those of nonpreceptor nurses. Study subjects were sampled out from those nurses who worked with two university hospitals where preceptor programs were implemented. The number of subjects totaled to 134, including 69 preceptor nurses and 70 nonpreceptor nurses. The score of preceptor nurses' clinical performance and job satisfaction revealed a higher value than that of nonpreceptor nurses. A similar result was also shown in the subdomains. However these difference were not statistically significant. Among all of the preceptor nurses, the highest number of preceptor experience was just one time. Except for five times in preceptor experience, the more the number of times of preceptor experience, the higher score in clinical performance. It was manifested that the number of preceptor experience was not related to job satisfaction. The score of preceptor nurses' clinica1 performance and job satisfaction revealed a higher value than that of nonpreceptor nurses. A similar result was also shown in the subdomains. However these difference were not statistically significant. The reward that preceptor nurses wished most was a reduction of the work load assigned to them. Currently preceptor nurses are only receiving a small quantity of financial reward related with their preceptor role. Most of preceptor nurses (96.8%) were not satisfied with their existing reward. Almost half of the preceptor nurses(43.5%) did not want to play a role as preceptor again. The reason why the scores of clinical performance and job satisfaction were low might be attributed to the inadequate preceptor training program and reward system. Appropriate knowledge and clinical skill are expected to enhance the level of preceptor nurses' clinical performance and appropriate internal and external reward to elevate the level of preceptor nurses' Job satisfaction. Therefore, it is needed for us to develop more effective preceptor education program, financial reward, support of colleague nurses and nursing managers, and adjust workload for the purpose of more effective preceptor programs.

강천일,현상훈,남언정,김건우,윤종수,서영익,이종명,김능수 慶北大學校 醫科大學 1996 慶北醫大誌 Vol.37 No.3

목적 : 기관지천식 환자에서 고장액 식염수의 흡입은 기도수축을 유발할 수 있으며 이는 운동유발성 천식반응과 밀접한 관계가 있는 것으로 알려져 있다. 저자들은 알레르겐 흡입이나 운동에 의해 유발되는 천식에 예방효과가 있는 것으로 알려진 disodium cromoglycate(DSCG), furosemide 및 heparin 흡입이 4.5% NaCl 기관지유발검사(BPT)에 미치는 영향을 조사하였다. 대상 및 방법 : 4.5% NaCl BPT에서 양성반응을 보이는 기관지천식 환자 13명을 대상으로 하였으며 사용된 약물은 furosemide 40㎎, DSCG 40㎎ 및 heparin 1,000μ/㎏이었다. 먼저baseline 4.5% NaCl BPT를 시행한 다음 이들 약물로 전처치후 다시 4.5% NaCl BPT를 시행하여 약물의 효과를 관찰하였다. 결과 : Furosemide 40㎎, DSCG 40㎎및 heparin 1,000μ/㎏의 흡입 전처치는 고장액 식염수에 의한 기도수축 반응에 뚜렷한 예방효과를 보였다. Furosemide와 DSCG로 전처치한 군(n=6)에서 이들의 기도수축 방어율은 각각 100.6±6.6%, 91.1±17.2%였으며 furosemide와 heparin으로 전처치한 군(n=7)에서는 각각 58.7±29.2%, 59.0±51.1%로서 각 군에서 이들 약제간의 방어율에는 유의한 차이가 없었다. 결론 : Furosemide(40㎎), DSCG(40㎎) 및 heparin(1000μ/㎏)의 흡입 전처치는 고장액 식염수에 의한 기도수축 반응에 뚜렷한 예방효과를 보였으며, 적어도 이 용량에서 기도수축 예방 정도에는 유의한 차이가 없음을 알 수 있었다. Background: Hypertonic saline (4.5% NaCl) inhalation is known to induce broncho-constriction by affecting mast cell, epithelial cell and vagal afferent pathway in some asthmatics. Disodium cromoglycate (DSCG) is known to have a preventive effect on allergic asthma and exercise induced asthma, and recently it was reported that furosemide and heparin had similar effect. The purpose of this study was to evaluate the effects of furosemide, DSCG and heparin on hypertonic saline provocation test in asthmatics. Methods: Thirteen asthmatics with a positive response to hypertonic saline challenge were enrolled. Hypertonic saline and test drugs were generated by ultrasonic nebulizer. After taking baseline 4.5% NaCl challenge, subjects were rechallenged with 4.5% NaCl after inhalation of furosemide 40㎎, DSCG 40㎎ or heparin 1,000μ/㎏. Results: 1. There was a significant positive relationship between PC_20-methacholine and PTM-4.5% NaCl(r=0.5575, p = 0.024). 2. Furosemide, DSCG and heparin had no direct bronchodilating effects. 3. Premedication of furosemide and DSCG(n=6) showed significant protective effects on 4.5% NaCl induced broncho-constriction. The average protection rate were 100.6±6.6% and 91.1±17.2%, respectively. 4. Premedication of furosemide and heparin(n=7) showed significant protective effects on 4.5% NaCl induced broncho-constriction. The average protection rate were 58.7±29.2% and 59.0±51.1%. respectively. Conclusions: Furosemide(40㎎), DSCG(40㎎) and heparin(1.000μ/㎏) had significant protective effects on hypertonic saline induced broncho-constriction in asthmatics, and there were no significant differences in their potency of protection rate.

Pre-validation study of spectrophotometric direct peptide reactivity assay (Spectro-DPRA) as a modified in chemico skin sensitization test method

Seo Jung-Ah,Cho Sun-A,Park Chang Eon,Seo Dong Hyuk,Choi Myungsuk,An Susun,Kim Bae-Hwan 한국독성학회 2022 Toxicological Research Vol.38 No.4

Skin sensitization is induced when certain chemicals bind to skin proteins. Direct peptide reactivity assay (DPRA) has been adopted by the OECD as an alternative method to evaluate skin sensitization by assessing a substance's reaction to two model peptides. A modified spectrophotometric method, Spectro-DPRA, can evaluate skin sensitization, in a high throughput fashion, to obviate some limitations of DPRA. Pre-validation studies for Spectro-DPRA were conducted to determine transferability and proficiency, within- and between-laboratory reproducibility, and predictive ability based on GLP principles at three laboratories (AP, KTR, and KCL). All laboratories confirmed high (> 90%) concordance for evaluating the sensitivity induced by ten chemical substances. The concordance among the three tests performed by each laboratory was 90% for AP, 100% for KTR, and 100% for KCL. The mean accuracy of the laboratories was 93.3% [compared to the standard operating procedure (SOP)]. The reproducibility among the three laboratories was as high as 86.7%; the accuracy was 86.7% for AP, 100% for KTR, and 86.7% for KCL (compared to the SOP). An additional 54 substances were assessed in 3 separate labs to verify the prediction rate. Based on the result, 29 out of 33 substances were classified as sensitizers, and 19 out of 21 identified as non-sensitizers; the corresponding sensitivity, specificity, and accuracy values were 87.9%, 90.5%, and 88.9%, respectively. These findings indicate that the Spectro-DPRA can address the molecular initiating event with improved predictability and reproducibility, while saving time and cost compared to DPRA or ADRA.

호랑이 이야기의 어린이용 공연 콘텐츠 활용 방안

서가언(Seo Ga Eon) 한국문화콘텐츠학회 2016 문화예술콘텐츠 Vol.- No.17

현대에 들어서 어린이용 콘텐츠의 시장이 점차 확대되는 추세이지만 어린이용 공연콘텐츠의 창작소재와 무대 연출 기법이 다양화되지 않아 새로운 공연콘텐츠의 공급이 원활히 이루어지지 않고 있다. 본 연구는 그 대안으로 호랑이 이야기에서 어린이용 공연콘텐츠의 창작소재를 개발할 것을 제안하고, 호랑이 이야기를 활용한 어린이용 공연콘텐츠의 질적 성장을 위한 방안을 논의하는 것을 목적으로 하였다. 호랑이 이야기를 창작소재로 활용한 어린이용 공연콘텐츠의 제작현황을 보면 《한국구비문학대계》속 호랑이 이야기 중에서도 어린이용 공연콘텐츠로 활용되고 있는 호랑이 이야기는 극히 제한적이라는 것을 알 수 있다. 이를 야기하는 극적 구성상의 문제를 해결하기 위해서는 기존의 작품을 재가공 하는 관례에서 벗어나 지금껏 활용되지 않았던 새로운 호랑이 이야기를 발굴하여 소재로 활용하되 세대를 아우르는 도덕관념과 현 시대상황에 맞는 가치관을 반영해야하고. 장르에 얽매이지 않는 새로운 콘텐츠 개발을 염두에 두고 희곡 개작을 보다 유연하게 해야 한다. Although the market for contents for kids is ever increasing in the modern society, there is no smooth supply of new performance contents because there is a lack of diversity in creative subjects and stage management techniques for performance contents for kids. The following study suggests the use of tiger stories once favored the most by storytellers as a background for creative subject development as a solution to the above mentioned problem. By reviewing the current production status for performance contents for kids based on creative materials from tiger stories, there s a lack of use of tiger stories. The following study concludes that in order to solve the problems arising from dramatic structure, there needs to be new contents development not limited to a specific genre, flexible adaptation of plays and the need to move out of existing tradition of rehashing previous works but utilize topics that haven t been discovered such as tiger stories.

서원필(eon Pheel Seo),장인성(In Seong Jang),현종명(Jong Myung Hyun),김두한(Doo Han Kim),김홍직(Hong Jig Kim),김판식(Pan Sik Kim) 대한피부과학회 1984 대한피부과학회지 Vol.22 No.1

Frey syndrome is characterized by sweating and flushing on the auriculotemporal region in respense to gustatory stimuli following surgery, trauma or irfection of the parotid areas. A 22-year-old man had received a surgery for sclerosis and hypertrophy of the left mandible. Two months after operation gustatory sweating occurred, whenever he eats, on the malar area without any detectable flushing or sensory impairment. Sweating starts in 30 seconds during food intake and is clearly visible with naked eyes within 2 minutes. This syndrome is encountered uncommonly to the dermatologic practitioners but more cases might be discovered if more attention could be given to this condition.

청소년 사이버 폭력 관련 요인에 관한 메타분석

서봉언 ( Seo Bong-eon ) 안암교육학회 2016 한국교육학연구 Vol.22 No.3

최근 청소년의 사이버 폭력의 양상이 심각해짐에 따라 학문적 관심이 늘고 있으며, 또한 청소년 사이버 폭력을 예방하고 적절히 대응하기 위한 전략 수립도 필요한 시점이 되었다. 이에 청소년 사이버 폭력 관련 최근 연구물들을 수집하여 사이버 폭력 관련 변인을 탐색해봄으로써 이를 선도적으로 예방하고 대응하기 위한 기초자료를 제공하고자 우선 사이버 폭력관련 변인을 살펴보고, 다음으로 사이버 폭력 유형별 관련 변인을 분석하였다. 본 분석에 앞서 수집한 연구물 26개 자료(k=440)의 출판편향을 확인한 결과, 출판 편향을 없는 것으로 판단되었다. 총 포함된 청소년 샘플수는 22,544명이다. 우선 사이버 폭력을 하위유형을 나누지 않고, 관련 요인별 메타분석을 실시한 결과, 위험요인이 339개의 데이터가 수집되어 가장 많은 연구가 이루어지고 있었으며 효과크기도 .319로 중간 수준의 효과크기를 나타내고 있었다. 다음으로 인구사회학적 요인이 .135로 낮은 수준의 효과크기, 억제요인은 -.096로 매우 미미한 효과크기로 밝혀졌다. 다음으로 사이버폭력 유형별 메타분석 결과를 살펴보면, 대부분의 연구들이 하위유형으로 나누어지지 않거나 사이버 폭력의 단일지표로 연구가 되고 있는 것으로 보이며 사이버폭력과 관계를 보면 위험요인, 억제요인, 인구사회학적 요인 순으로 관련이 높은 것으로 확인되었다. 본 연구는 사이버 폭력에 관한 국내 연구물들을 수집하여 통합적 관점에서 분석하였다는 데에 의의가 있다. This study is designed to explore the factors for juvenile cyber violence in Korea. In this meta-analysis of articles, 440 effect sizes from 26 studies were included, representing the testing of 22,544 adolescents. The results were as follows: First, the overall effect size of risk factors was .319, which shows the medium effect, and that of social demographic factors was .135, which is a small effect size; however, the effect size of restraints was marginal at -.096. This suggests that many recent studies of cyber violence have focused on risk factors more so than on other factors, thus showing those medium effect sizes. Second, in the analysis of cyber violence types, many studies have not categorized cyber violence or divided it into subtypes. As a result, many of them reported a single measurement of cyber violence. Cyber violence was highly related to risk factors such as cyber violence experiences, depression, and stress. In the findings, the restraints were related and social demographic factors were lowest. To sum up, this study first attempted to collect and synthesize results of juvenile cyber violence, and ultimately offer an integrated perspective. To extend understanding of juvenile cyber violence, however, more research is needed.

청년 대졸자의 대학만족도와 직무만족도와의 관계분석 -취업준비행동의 매개효과를 중심으로-

서봉언 ( Bong Eon Seo ),박명희 ( Myung Hee Park ),김경식 ( Kyung Sik Kim ) 대경교육학회(구 우리교육학회) 2013 교육학논총 Vol.34 No.1

본 연구의 목적은 청년 대졸자들이 지각한 대학교육 만족, 취업준비행동, 직무 만족의 구조적 관계가 어떠한지 살펴보고 나아가 2007년, 2008년, 2009년 대학 졸업자들에게 있어 그 관계의 영향력 추이 정도를 탐색하고자 수행되었다. 연구결과 만족스러운 대학교육을 경험한 사람일수록 취업준비를 많이 하고, 직무만족이 높아짐이 확인되었다. 그리고 다집단 분석의 결과 졸업 집단에 따른 구조 모델 요인들 간의 유의한 차이가 있었다. 연구 결과로는 첫째, 집단 모두가 교육만족이 직무만족과 취업준비행동에 정적인 영향을 주고 있는 것으로 밝혀졌다. 둘째, 2007년, 2008년 대졸자 집단들은 취업준비행동이 직무만족에 유의미한 영향을 미치고 있었으나 2009년 대졸자 집단은 취업준비행동이 직무만족에 유의미한 영향을 미치지 않았다. 이는 시간의 흐름 따라 사교육에 치중된 취업준비행동보다는 학교의 전공교육내용이나 전공의 수업 질 등이 직무만족에 영향을 더 미치고 있음을 알 수 있었다. This study is conducted to explore the structural relationship of university education satisfaction, job preparation activities and job satisfaction. The difference is also analyzed among university graduates groups in 2007, 2008, and 2009. According to the findings, people who have experienced successfully in university education would have possibility to do more job preparation activities and be satisfied with their jobs. The detail results of this study were as follows: First, university education satisfaction had positive effect on both job preparation activities and job satisfaction in all three graduates groups. Second, job preparation activities had positive effect on job satisfaction in 2007 and 2008 graduates group except 2009. Taken together, the quality of higher education would have much more positive effect on job satisfaction than job preparation activities.

중학생의 다문화 수용 관련 요인 탐색

서봉언(Bong-Eon Seo),조현미(Hyun-Mi Jo),김민영(Min-Young Kim) 중앙대학교 문화콘텐츠기술연구원 2015 다문화콘텐츠연구 Vol.0 No.19

최근 다문화 사회로 이행됨에 따라 청소년들의 다문화 수용성이 중요한 변인으로 꼽히고 있다. 이는 자라나는 세대로서 청소년들이 소수집단에 대한 인식 및 수용 태도가 우리 사회의 통합을 유도하는 데 필수요인이 될 수 있다. 따라서 본 연구는 청소년들의 다문화 수용성에 미치는 요인들을 분석하고자하였다. 한편 최근 다문화 수용성을 일차원적인 변수가 아니라 하위 차원을 가진 변수로 객관적인 사회적 거리에 의한 개념으로 봄에 따라, 다문화 수용성을 이웃 수용과 결혼 수용이라는 두 하위 변수를 상정하여 그 차이를 살펴보았다. 이웃 수용과 결혼 수용 모두에 영향을 미치는 변수는 ‘공동체 의식’으로 나타났다. 이는 다문화 수용성은 공공선을 추구하는 공동체주의와 관련이 깊다는 선행연구와 일맥상통하는 결과이다. 즉 다양한 민족과 서로 다른 가치관을 가진 사회 구성원들이 모여 있는 사회에서 공동체 의식은 서로의 결속을 다지고 상호책임감을 증진시킬 수 있는 유용한 도구가 될 수 있다. 본 연구는 청소년 다문화 수용성에 영향을 미치는 변인을 탐색함에 있어 그 수준을 나누어 이웃 수용이라는 소극적 수준과 결혼 수용이라는 적극적 수준의 차이를 관찰하였다는 점에서 의의가 있다. 특히 공동체 의식이 청소년 다문화 수용에 긍정적인 영향을 미치는 것으로 나타나 다문화 수용과 공동체 의식 간 관계를 파악할 필요성을 제기하였다는 데 시사하는 바가 크다. 그러나 2차 자료를 활용하여 다양한 변수의 영향력을 살펴보지 못하였다는 한계점이 있다. The rapid increase of multiculturalism in South Korea over the past few decades has prompted greater emphasis on adolescents’ multicultural acceptance. This study was conducted to explore factors influencing multicultural acceptance for middle school students along two categorical lines: neighbor acceptance and marriage acceptance, using Binary Logistic Regression with Korea Children and Youth Panel Survey. The key factor influencing both neighbor and marriage acceptance was ‘sense of community’. This result showed that multicultural acceptance is deeply related to sense of community which pursues the common good and helps integrate society. The significance of this study is the empirical attempt to investigate the factors influencing adolescents’ multicultural acceptance. The study’s limitation is in its not exploring many variables such as previous educational experience, language ability and mass media. Further research is recommended.
