Jun-Hwan Yang(양준환) 한국경영교육학회 2015 경영교육연구 Vol.30 No.4

최근 기업가정신은 지역경제와 국가경제를 활성화시키기 위한 핵심적인 기초 요인으로 주목 받아 왔다. 이러한 결과 대학에서의 기업가정신교육 중요성이 세계적으로 큰 관심을 불러일으켜 왔으며 또한 미래 기업가 양성을 위한 중요한 도구로 받아들여지고 있다. 중국은 최근 세계 경제대국으로 부상하고 있으며 한·중 양국 간의 경제의존도도 심화되어 가는 상황이다. 본 연구는 국가 간 비교연구로써 한국과 중국대학생들을 대상으로 기업가정신교육이 대학생들의 자기효능감과 기업가적 동기를 촉진시켜주는가를 규명하기 위하여 진행되었다. 회귀분석결과 기업가정신교육은 한국과 중국 대학생의 기업가적 동기에게 긍정적인 영향을 주는 것으로 나타났다. 기업가정신교육은 또한 대학생들의 자기효능감에도 유의한 영향을 주고 있음을 알 수 있었 다. 자기효능감은 대학생들의 기업가적 동기와 정(+)의 관계를 가지고 있으며 기업가정신교육과 기업가적 동기 사이에 유의한 부분 매개효과의 영향력을 보이는 것으로 나타났다. 본 연구는 기업가정신교육이 대학생들의 기업가적 동기를 촉진시키는 한편 자기효능감을 증진시킨다는 측 면에서 기업가정신 활성화를 위한 매우 중요한 선행변수임을 규명하였다. 이상의 연구결과에 대한 논의와 연구의 한계점을 제시하였다. The importance of entrepreneurship education is getting emphasized world-wide, since there has been general agreement on entrepreneurship as a vital element for revitalizing local and national economy. This study is designed to identify the practical role of entrepreneurship education whether it fosters self-efficacy and entrepreneurial motivation of university students as a cross-cultural study between Korea and China. Summary of the findings is as followings. Entrepreneurship education has a positive effect on entrepreneurial motivation for both Korean and Chinese university students. Self-efficacy of university students in both countries is influenced positively by entrepreneurship education. Finally, self-efficacy affects entrepreneurial motivation of students positively. Self-efficacy mediates partly the relationship between entrepreneurship education and entrepreneurial motivation in both countries. The findings imply that entrepreneurship education is the prerequisite factor in facilitating entrepreneurial activities among university students.

역사적 실존 효녀 심청 소고

고준환 ( Jun Hwan Go ) 한국청소년효문화학회(구 한국청소년문화학회) 2012 韓國의 靑少年文化 Vol.19 No.-

효는 인간사회의 기본윤리이며, 부모를 잘 섬기는 일이다. 우리나라는 상고 시대인 환단조선 때부터 민족경전인 천부경, 삼일신고, 참전계경에 기초한 전통도맥인 신선도 5상에 효가 포함되고 생활의 바탕으로 삼았다. 환국5훈, 환웅7훈, 단군8조교 등이 이를 잘 뒷받침한다. 우리 국민 정서에 깊이 뿌리박은 효사상의 상징은 만고효녀 심청전이다. 그런데 심청은 백제시대 전기, 전라남도 곡성출신의 역사적 실존인물이다. 본명은 원홍장이고, 맹인 아버지는 원량이었다. 원홍장(심청)은 아버지와 성공대사의 약속 즉 공양미 3백석을 보시하고 눈을 뜨게 한다는 내용에 따라 자기를 헌신한다. 그녀는 쌀 3백석 값을 받고 중국 절강성 주산시 보타도 심가문진(심청마을)에 사는 국제 귀족 상인 심국공 일행을 따라 중국으로 간다. 원홍장은 심국공의 양녀가 되니 이름을 심청으로 바꾸고, 이어서 진나라 혜제의 문명황후가 된다. 진서에는 원희(元姬)로 기록돼 있다. 문명황후는 당시의 관음불교에 심취하여 백제 곡성 관음사에 5백나한, 관음보살상, 소조 금니상 등을 보내고, 심청의 아버지는 눈을 뜨게 된다. 효를 비롯한 신선도 5상의 기본윤리가 복잡다단한 현대사회에도 필요하다. The filial piety is the basic ethics that is devotion to the parents. Our country had used the Seen-Sun-Do 5 sang containing the filial piety to the bottom of life from the earliest ancient Hwan-Dan-Chosun. The traditional TAO is based on the national bible, namely, Chunbukyung, Samilsingo, Chamjungekyung. There are Hwankuk-ohun, Hwanwung-chilhun, Dangun-paljokyo. The thought-symbol of our country`s filial piety is the biography of Simchung rooted in Koreans pathos. However Simchung is the historical person of Julanamdo-Goksung at Baekje Dynasty. Her original name is One-Hongjang and her blind father is One-Ryang. One-Hongjang namely Simchung decided her mind devoting for her father`s eye to be open for the purpose of sending 300 rice bag to Buddha through Sungkong monk. After receiving 300 rice bags, she had gone to the China Julgangsung-Jusan City, Bota island following the international trader Simkukgong group. She became the daughter-in-law of Simkukgong, and next her name is changed to Simchung. After that, she became the Queen of Emperor Heje in Chin dynasty and so called the Moonmyung Empress. That was recorded One-Hee in the history of Chin dynasty. Moonmyung Empress had sent to Goksung Kwanin Temple statues of 500 Arhat, Avalokitasdesvara and the golden Buddha. At that time, her blind father saw the light through opening eyes. Seensun-do 5 Sang containing the filial piety is necessary as the basic ethics now here.

Moon, Sung-Hwan,Kim, Seong-Oh,Yu, Hyung-Seong,Choi, Byung-Jai,Choi, Hyung-Jun,Lee, Jae-Ho 大韓小兒齒科學會 2006 大韓小兒齒科學會誌 Vol.33 No.2

이번 연구의 목적은 혼합치열기 아동에서 미맹출된 견치와 소구치의 크기를 예측하는데 있어서 한국인에 맞는 방정식을 만들기 위함이다. 미맹출 치아의 크기를 예측하는 것은 혼합치열기 교정 진단과 치료계획 수립에 있어서 매우 중요하다. 미맹출된 견치와 소구치 크기를 예측하는 방법은 몇가지가 있지만 그중에서도 가장 흔하게 쓰이는 것이 모이어의 예측표와 다나카와 존스턴의 방정식이 있다. 하지만 그것들은 백인을 위해서 제작된 것이고 치아 크기는 인종에 따라서 다르다고 알려져 있다. 이번 연구에서는 치아크기를 측정하여 하악 영구 절치의 크기 합과 견치 및 소구치의 크기 합 사이의 상관관계를 구하고 회귀방정식을 이용해서 한국인에 맞는 예측표를 만들었다. 연세대학교 치과대학에 재학중인 178명의 한국 학생(남 108명, 여 70명, 평균연령 21.63)을 대상으로 실험하였다. 영구치의 근원심 폭경을 석고모형상에서 calipers를 이용해서 측정하였다. 성별간의 치아 크기는 차이가 있었다(p<0.05). Correlation coefficient는 0.57에서 0.64의 범위였고, standard errors of the estimates 는 여성에서 0.6으로써 남성보다 우수하였다. r^(2)값은 0.27에서 0.41의 범위를 나타내었다. Estimating the size of unerupted teeth is an essential aspect of orthodontic diagnosis and treatment planning in the mixed dentition. Several methods were introduced and used for the prediction. The most common methods among these would be Moyers probability chart and Tanaka and Johnston equations. These are currently used widely, but they were developed for Caucasians. Because there are clear racial differences in teeth size, the objectives of this study were to produce correlation coefficients between the combined mesiodistal widths of the permanent mandibular incisors and those of the canines and premolars for each quadrant, and prediction tables with regression equations, specifically for Korean. 178 young adults (70 women, 108 men, mean age 21.63 years) were selected from the College of Dentistry, Yonsei University, Seoul, Korea. The mesiodistal crown diameters of the permanent teeth were measured with calipers. Significant sexual dimorphism was found in tooth sizes. The correlation coefficients between the total mesiodistal width of the mandibular permanent incisors and those of the maxillary and mandibular canines and premolars were found to be between 0.52 and 0.64. The standard error of the estimatation was better (0.60) for women and the r^(2) values ranged from 0.27 to 0.41 for both sexes, Prediction tables were prepared for Korean. This study showed larger canine and premolar diameters than Tanaka and Johnston's and Moyers' studies which might be due to the racial differences. Further investigations with a larger sample size will be needed for more representative data on the Korean population.

목적: 경골 원위부 골절의 치료에 있어 최소 침습적금속판 고정술과 관혈적 고정술에 대한 비교를 통한 효율성에 대한 연구고찰을 하고자 한다. 대상 및 방법: 2001년 6월부터 2004년 6월까지 경골 원위부 골절에 대하여 수술을 시행한 최소 1년 이상의 추시가 가능하였던 30예 중 최소 침습적 금속판 고정술을 시행한 15예를 A군, 관혈적 금속판 고정술을 시행한 15예를 B군으로 나누어 수술시간, 술 후 재활, 술 후 운동범위, 동통에 대하여 McLennan과 Ungersma의 기준을 이용한 임상평가, 술 후 염증반응에 대한 C-반응성 단백 및 술 후 합병증을 후향적으로 비교 분석하였다. 결과: A군과 B군의 수술시간은 각각 63분 (45∼105)/129분 (80∼120), 능동적 관절 운동가능시기는 8.3일 (6∼14)/15.8일 (13∼21), McLennan과 Ungersma의 기준에 의한 임상평가는 두 군 모두에서 대부분 양호 이상의 결과를 보였으나, B군에서는 보통 1예가 있었다. 술 후 3일, 7일째 각각 시행한 CRP는 A군에서는 4.0 mg% (범위: 0.9∼7.2)/0.5 mg% (0.1∼1.5), B군에서는 7.97 mg% (2.8∼14.6)/1.0 mg% (0.3∼1.6)로 A군에서 조직손상이 적고 회복이 빨랐다. 술 후 합병증으로는 A군에서는 표재성 감염 1예와 5도 이상의 족관절 외반변형 1예가 있었고, B군에서는 표재성 감염 1예, 감염성 불유합 1예와 10도 미만의 족관절 배굴장애를 보이는 경우가 2예 있었다. 결론: 경골 원위부 골절의 수술적 치료에서 최소 침습적 금속판 고정술이 관혈적 고정술에 비해 조직의 염증반응과 합병증이 적고 수술시간 및 술 후 재활 등에서 보다 효율적인 술식으로 사료된다. Purpose: To evaluate the efficacy of the surgical treatment through the comparison of MIPPO vs open plate fixation in the treatment of the distal tibia fracture retrospectively. Materials and Methods: 30 patients with distal tibia fracture from Jun. 2001 to Jun. 2004 were divided into two groups depending on the surgical method. Minimum follow up was 12 months. Group A consisted of 15 patients treated with MIPPO, Group B was 15 patients treated with open plate fixation. The clinical outcomes were evaluated retrospectively from operation time, rehabilitation, ROM, interval change of postoperative CRP to assess postoperative inflammatory reaction, postoperative complications and clinical result with the use of McLennan and Ungersma criteria. Results: There were no significant differences in clinical result by McLennan and Ungersma criteria in both groups. The postoperative 3 days and 7 days CRP were 4.0 mg% (0.9∼7.2)/0.5 mg% (0.1∼1.5) in group A and 7.97 mg% (2.8∼14.6)/1.0 mg% (0.3∼1.6) in group B, shows more minimal tissue injury and early recovery in group A. Operation time in group A was shorter than group B. Normal recovery of ROM was quicker in Group A. In complications, group A showed one superficial infection and one angular deformity and group B showed one superficial infection, one infected nonunion and two ankle stiffness. Conclusion: There were no significant differences in clinical result and bony union. MIPPO technique is superior to group B in view of the minimal tissue injury, complications, operation time and postoperative rehabilitation.

To study synaptosomal Na-K-ATPase in the renal hypertensive rats, right kidney was removed and left renal artery was partially ligated 9external diameter=0.38mm) for pyertensive group. For control, right kidney was removed. At four weeks after operation, blood pressure ws monitored with physiography from carotid artery. Synaptosome was prepared from cerebrum to investigate the activity of Na-K-AFTase in the absence of the presence of saponin, Rb-uptaek and ouabain binding experiment. Results are as follows; 1. Blood pressure was significantly increased to 177.4/121.6mmHg in 1-kidney hypertensive rat. 2. In the presence of saponin, total, EGTA-sensitive, azide-sensitive and Na-K-ATPase activity were increased about two folds compared to those in the absence of saponin. 3. In the absence of saponin, Na-K-ATPase activity was significantly decreased compared to control group. These results were the same as in the presence of saponin. 4. ^86Rb-uptake inhibited by ouabain was significantly decreased (about 37%) in the hypertensive group compared to control group. 5. In the ouabain binding experiment, vlaue of Bmax in hypertensive group was decreased signficantly(about 32%), but there was no differnece in the value of Kd between both groups. From these results, it is suggested that the function of central nervous system may be altered due to decreased number of pump or activity of Na-K-ATPase in the 1-kidney, 1-clip hypertensive rats.

급성골수백혈병에 대한 관해유도화학요법 후의 Granulocyte Colony-stimulating Factor의 효과

윤환중,최지영,전의건,길준영,조덕연,김삼용 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.2

Granulocyte colony-stimulating factor(G-CSF) have been shown to hasten the recovery of neutropenia following anti-cancer chemotherapy. There are controversial opinions on the use of G-CSF in acute myelogenous leukemia(AML) because clonogenic studies have shown that G-CSF stimulates leukemic colonies as well as granulocyte colonies. In this study, we evaluated the effectiveness and safety of recombinant human G-CSF after induction chemotherapy with DAV regimen(Ara-C 100mg/㎡ day 1-8, Doxorubicin 45mg/㎡ day 3-5, VP-16 100mg/㎡ day 6-8) in 9 patients with AML. G-CSF therapy(200 ㎍/㎡/day) was begun 2 days after the end of chemotherapy and continued for 10 days. 17 AML patients who recieved the same chemotherapy before the onset of this study were used as historical control. G-CSF shortened the duration of granulocytopenia (less than 500/㎣) significantly (13 vs 23 days, p<0.001), but it had no effect on platelet recovery. Although the incidence of febrile episodes was almost the same, the duration of febrile episodes was shorter in the group treated with G-CSF( 5 vs 12 days, p=0.03). There was no evidence that G-CSF accelerated the regrowth of leukemic cells and the complete remission rates between the 2 groups were not different. These results show that G-CSF accelerates the recovery of granulocytopenia and shortens the febrile days after chemotherpy in patients with AML, without affecting the regrowth of leukemic cells.
