한류문화를 통한 외국인 유학생의 문화적응과정: 한국춤을 중심으로
김재은(Kim Jea-Eun),윤필규(Yoon Pil-Kyu) 학습자중심교과교육학회 2017 학습자중심교과교육연구 Vol.17 No.3
이 연구는 한류문화로써 한국의 전통문화인 한국춤을 경험한 외국인 유학생들의 한국사회에서 문화적응과정을 분석한 연구이다. 2016년 9월∼2016년 6월까지 총 15 명의 외국인 유학생을 연구 참여자로 선정하여 심층면담, 참여관찰, 문서 자료를 수집하였고 근거이론연구방법으로 분석하였다. 외국인 유학생들은 한류문화, 학업 실천, 한국의 긍정적 이미지로 유학을 결정하였다. 그러나 언어소통, 문화차이, 무시와 차별, 경제부담 문제로 유학생활에 많은 어려움을 겪었다. 외국인 유학생들이 한국 문화를 경험하는 한국춤 수업을 약 1년 동안 수강하며 다양한 한국의 다양한 모습을 배우게 되었고 신체와 정신의 건강획득, 도전과 성취감, 유학생들과의 커뮤니티 형성, 한국문화에 대한 정보와 지식을 얻게 되었다. 이후 한국춤 수업의 경험들이 매개가 되어 한국의 문화를 이해하고 적응하며 새로운 문화정체성이 형성되었다. 외국인 유학생들은 한국춤을 비롯한 한국에서 다양한 경험을 기반으로 진로를 계획하고 설계하게 되었다. This study presents an investigation into the cultural adaptation process of foreign students that experienced the Korean dance, an element of traditional Korean culture, as part of Korean Wave culture. The subjects include total 15 foreign students. Data were collected from them through an in-depth interview, participant observation, and documentation and then analyzed in the ground theory methodology. The foreign students decided to study in South Korea for the Korean Wave culture, practice of learning, and positive images of South Korea. They, however, faced a lot of difficulties with their life in the nation as foreign students due to language barriers, cultural differences, disregard and discrimination, and economic issues. After taking a Korean dance course to experience the Korean culture for about a year, they got to learn the various aspects of the nation, acquire physical health, fulfill a challenging and achievement spirit, form a community with fellow foreign students studying in the nation, and obtain information and knowledge about the Korean culture. They understood and adjusted themselves to the Korean culture and formed new cultural identity through the medium of experiences with the Korean dance classes. In addition, they planned and designed their careers based on the diverse experiences they had in the nation including the Korean dance.

양흡입 펌프의 V-cut이 공동현상 개선에 미치는 영향
조은희(Eun-Hee Cho),김민기(Min-Ki Kim),김재은(Jae-Eun Kim),김호중(Ho-Joong Kim),박정현(Jeong-Hyeon Park),윤종웅(Jong-Woong Yoon),김윤제(Youn-Jea Kim) 대한기계학회 2021 대한기계학회 춘추학술대회 Vol.2021 No.11
As people use more energy, the demand for optimal centrifugal pumps have increased. Among various pump performance evaluation indicators, efficiency and NPSH3 are important factors that improve pump performance. So, the influence of V-cut configurations on the efficiency and cavitation of the double-suction pump was studied. V-cut was applied by modifying the impeller trailing edge so forming V-shaped cut at the impeller exit. By setting the vertex coordinates of V-cut as parameters, optimization was conducted. A numerical analysis was conducted using ANSYS CFX. Total 9 design points were designed using central composite design (CCD), one of the designs of experiment (DOE)techniques. Response surface method (RSM)was used to predict optimized V-cut design. We compared the NPSH3 point, where 3% of the total head decreases, to find the cavitation. In the optimized model, the efficiency was increased by 5.06% and cavitation was decreased.

요추간판 탈출증 환자에서 화학적 수핵용해술과 기존의 후궁절제술의 예후분석
김재은,박명찬 의과학연구소 1993 全北醫大論文集 Vol.17 No.2
Chemonucleolysis with Chymopapain has been shown to be an effective alternative to surgery for the patients with lumbar disc herniation who failed to be treated conservatively. All the patients were diagnosed using either myelogram, sopine C-T, MRI& myelo-CT. If the radiological examination showed an extruded migrated disc, as well as spondylosisthesis and spinal stenosis, a laminectomy were performed. Otherwise patients underwent chemonucleolysis. Of the 536 patients, 488 underwent laminectomy & 48 chemonucleolysis. The results obtained from 398 cases out of 536 cases which could be followed are as follows. 1) 63% of patients were from the 20th decade to the 50th decade. 2) The most common site was L4-5 interspace, followed by L5-Sl interspace. 3) The majority of cases occured at one level. 4) Of 48 chemonucleolysis patients, excellent & good results were obtained in 89.6%. 5)In conclusion, above finding suggest that if there is an appropriate selection of patients and technically correct performance of the p개cedure by experienced surgeon, chemonucleolysis is a safe & effective neurosurgical method for treatment of herniated lumbar disc.

1987년 1월부터 1990년 12월까지 4년동안 뇌전산화 단층촬영을 이용하여 진단받은 고혈압성소뇌출혈 28예를 대상으로 임상적 소견과 방사학적 소견, 그리고 예후를 분석한바 다음의 결론을 얻었다. 1) 사구체조의 모양이 정상인 경우 7예중 6예(85%)에서 좋은 예후를 보였다. 그중 수두증이 없었거나 출혈후 48시간내에 수두증에 대한 shunt시행을 받았던 5예 모두에서(1예에서만 혈종제거술 시행)좋은 예후를 보였다. 반면 48시간후 shunt 시행한 2예중 1예에서 좋은 예후를 보였다. 따라서 폐쇄성 수두증이 존재하면 조기에 이를 호전 시켜야 하며 혈종 제거술은 불필요한 것으로 여겨진다. 2) 사구체조가 부분 폐쇄된 경우 9예중 7예(78%)에서 좋은 예후를 보였다. 그 중 수두증이 없거나 출혈후 48시간내 수두증에 대한 shunt시행을 받었던 6예중 5예(83%)에서 좋은 예후를 보였으며, 혈종제거술을 함께 시행하였던 4예는 모두 좋은 예후를 보였으나, 혈종제거술을 시행치 않았던 2예중 1예에서만 좋은 예후를 보였다. 반면 48시간후 수두증에 대한 shunt를 시행한 경우는 3예중 2예(67%)에서만 좋은 예후를 보였다. 따라서 조기에 혈종제거술과 수두증이 있다면 48시간내에 shunt를 시행해 주는 것이 좋을 것으로 여겨진다. 3) 사구체조의 완전폐쇄된 경우 12예 모두에서 혈종제거술과 수두증 호전과 관계없이 좋지 않은 예후를 보였다. 4) 이상을 연구 결과 뇌 전산화 단층 촬영상 사구체조의 폐쇄정도는 환자의 예후에 대한 지침과 치료방법을 선택하는데 유용하다고 생각되었다. The authors analyzed 28 cases with hypertensive cerebellar hemorrhage, diagnosed by computerized tomography(CT), between 1987 and 1990, in Chonbuk National University Hospital. The authors assessed the relationship of outcome to the CT appearance of the quadrigeminal cistern, which in some cases was obliterated by rostral displacement of the vermis resulting from the cerebellar mass. Obliteration of the quadrigeminal cisterns was classified on the CT scans into three grades : Normal (Grade Ⅰ), Compressed (Grade Ⅱ), or Absent (Grade Ⅲ). There were 7 cases with Grade Ⅰ, 9 with Grade Ⅱ, and 12 with Grade Ⅲ cisterns. Of the 28 cases, 6(85%) of those with Grade Ⅰ, 7(78%) of those with Grade Ⅱ, and none of those with Grade Ⅲ cisterns respectively returned to their previous activities at 6 months or more after onset. A Grade Ⅰ cisterns predicted a good outcome whether the hematoma was evacuated or not, as long as obstructive hydrocephalus, if present, was relieved early. However, a Grade Ⅱ cisterns was not predictive of a good outcome unless the hematoma was evecuated within 48 hours after onset of the hemorhage. A Grade Ⅲ cisterns predicted an unfavorable outcome. Taken together, these results strongly suggest that the CT grade of quadrigeminal cistern obliteration may be an indicator of outcome and may be useful in selecting treatment for patients with cerebellar heorrhage.

척추 전방전위증 환자에서 V.S.P(Variable Screw Placement) plate 사용에 대한 임상적 고찰
강재구,김재은 의과학연구소 1991 全北醫大論文集 Vol.15 No.3
From December 1989 to may 1991, 12 patients with spondylolisthesis were operated application of V.S.P(variable screw placement) spinal plate with total laminectomy in Department of Neurosurgery of Chonbuk national university hospital. Main symptoms were severe low back pain and lower extrenity radiating pain. Male to female ratio was 1:3. The age of patient was from 4th decade to 7th decade with the largest number in 4th decade. The result of operation were considered excellent in 7cases, good in 3cases and poor in 2cases.
