본 연구는 조경수용 무궁화 우수품종 보급을 위한 유전자원 수집과 특성을 평가하기 위해 최근 국내외에서 육성된 127품종의 1년생 접목묘를 이용하여 2014년부터 2015년까지 2년 동안 생육 및 형태적 특성조사를 실시하였다. 수집된 품종 중 화색 및 꽃이특이한 품종을 조사하여 무궁화를 조경수로 활용도를 높이는데 기여하고자 하였으며 얻어진 결과는 다음과 같다. 최근 국내외에서 육성된 품종들의 화색별 분류로는 크게 분홍색 단심(pink color with red eye spot), 흰색 단심(white color withred eye spot), 붉은 자주색 단심(purplish red color with red eye spot), 분홍보라색 단심(violet pink color with red eye spot), 심홍색단심(crimson color with red eye spot), 흰색 바탕에 붉은색 무늬의 이중색(asadal), 흰색(white color), 푸른색(blue color) 등 총 8종류로 분류되었다. 화색이 붉은 자주색으로서 적색이 강한 꽃으로 국내에서 육성된 품종으로 ‘광명’, ‘난파’, ‘노스페이스’, ‘불새’, ‘비단’,‘송암’, ‘영창’, ‘적퍼소’, ‘키호’, ‘탐라’, ‘화수레드’, ‘환희’ 등이 있었으며, 국외에서 육성되어 국내에 도입된 품종으로는 ‘Aphrodite’,‘Dr. Uemoto’, ‘Freedom’, ‘Pink Cup’, ‘PS 80-1’, ‘Purpureus Variegatus’, ‘Red Giant’, ‘Woodbridge’ 등이 있었다. 화색이 분홍보라색으로서 특이한 품종으로는 ‘꼬마’, ‘도투락’, ‘명미’, ‘병화’, ‘산처녀’, ‘태화’, ‘Hikari-hanagasa’, ‘Little Kim Violet’ 등이 있었다. 화색이 심홍색으로 기존의 꽃에서는 볼 수 없는 특이한 품종으로 ‘종무’와 ‘Ruffled Satin’ 등이 있었다. 최근 국내외에서 육성된 품종중 조경수용 소재로 보급할 수 있는 품종중 기존 품종에 비해 꽃의 크기가 큰 품종으로 무궁화 종간교잡종인 Hibiscus hybrid ‘Daewangchun’, ‘Daeil’,‘Jina’ 등이 있었다. 반면 꽃이 작고 조경적 가치가 높은 품종으로 ‘꼬마’, ‘미백’, ‘안동’, ‘릴킴’, ‘은하수’ 등이 있었다. 백단심계 무궁화‘꼬마’ 품종은 수고가 작은 왜성형으로 꽃의 크기가 5.2cm로 작은 소형화 품종으로 나타났다. 기존 품종에 비해 단심의 길이가 긴품종으로 ‘훈장’과 ‘하이리레드’가 있었다. 홍단심계 무궁화 ‘훈장’은 꽃의 크기는 12.0cm로 중간크기이나 단심길이는 4.8cm로 지금까지육성된 품종중 가장 긴 품종이었다. 또한 홍단심계 무궁화 ‘하이리레드’의 단심길이 역시 4.2cm로 꽃잎 길이에 비해 단심의 길이가 길어 조경적 가치가 높은 것으로 판단되었다. This study was carried out to characterize 127 recently developed cultivars of Rose of Sharon (Hibiscus spp.) in Korea and foreign Countries for landscape uses. The examined factors were growth characteristics such as tree height of a 1-year grafted plant(cm), plant type, growth habit, leaf characteristics such as shape and size, flower characteristics such as color, shape, size, and red eye during 2014 and 2015 for landscape uses. The results are obtained as follows; In the results of flower color of the 127 recently developed cultivars, pink color with red eye spot, white color with red eye spot, purplish red color with red eye spot, violet purple color with red eye spot, crimson color with red eye spot, asadal, blue color with red eye spot, and white color were distributed. In the flower characteristics, Hibiscus hybrid ‘Daewangchun’ had the largest flower size of 16.0cm out of the 127 cultivars. H. syriacus ‘Antong’, ‘Lil Kim’, and ‘Ggoma’ were cultivars with smaller flowers than other cultivars. H. syriacus ‘Hunjang’ had largest red eye, of 5.2cm of length compared to the other cultivars. The cultivars with unique flower color for landscape uses are H. syriacus ‘Kwangmyung’, ‘Nanpa’, ‘North face’, ‘Bulsae’, ‘Bidan’, ‘Songam’, ‘Youngchang’, ‘Jukpeoso’, ‘Kiho’, ‘Tamla’, ‘Hwasoored’ and ‘Hwanhee’. These flowers had a purplish red color and were developed in Korea. H. syriacus ‘Aphrodite’, ‘Dr. Uemoto’, ‘Freedom’, ‘Pink Cup’, ‘PS 80-1’, ‘Purpureus Variegatus’, ‘Red Giant’, ‘Woodbridge’ also had unique flowers with a purplish red color and were introduced from foreign countries. In addition, cultivars with violet pink flowers were H. syriacus ‘Ggoma’, ‘Doturak’, ‘Myungmi’, ‘Byunghwa’, ‘Sancheonyu’, ‘Taehwa’, ‘Hikari-hanagasa’, and ‘Little Kim Violet’. ‘Jongmoo’ and ‘Ruffled Satin’ had flowers with crimson color. Therefore, the new cultivars with unique flower colors were a promising cultivars to a woody landscape plant. Cultivars with large flower sizes were Hibiscus hybrid ‘Daewangchun’, Hibiscus hybrid ‘Daemang’, and Hibiscus hybrid ‘Jina’. H. syriacus ‘Ggoma’, ‘Mibeak’, ‘Antong’, ‘Lil Kim’, and ‘Eunhasu’ had small flower sizes. Cultivars with long red eye were H. syriacus ‘Hunjang’ and H. syriacus ‘Hi Lea Red’. Therefore, the new cultivars, Hibiscus hybrid ‘Daewangchun’, Hibiscus hybrid ‘Daemang’, Hibiscus hybrid ‘Jina’ with large flower sizes, H. syriacus ‘Ggoma’, ‘Mibeak’, ‘Antong’, ‘Lil Kim’, and ‘Eunhasu’ with small flower sizes, H. syriacus ‘Hunjang’ and H. syriacus ‘Hi Lea Red’ with long red eye, were promising cultivars to a woody landscape plant.

김광호,김정택,이서원,김혜숙,임현경,이춘수,선경,Kim, Kwang-Ho,Kim, Joung-Taek,Lee, Seo-Won,Kim, Hae-Sook,Lim, Hyun-Kung,Lee, Choon-Soo,Sun, Kyung 대한흉부심장혈관외과학회 1999 Journal of Chest Surgery (J Chest Surg) Vol.32 No.4

배경: 최근에 시작된 소절개선을 이용한 심장수은술 환자에게 미용상 효과가 좋으며, 통증이 적으며 빠른 회복을 가져온다. 본 교실에서는 그간 실시한 소절개심장수술의 현황을 임상고찰하였다. 대상 및 방법: 1997년 2월 흉골좌연종절개선으로 관상동맥우회술을 실시한 이후 1998년 11월까지 총 31례의 소절개술을 이용한 심장수술을 실시하였다. 남녀 비는 17:14였으며, 1세에서 75세까지의 연령분포를 보였다. 흉골좌연종절개술을 실시한 예는 9례로 관상동맥 질환으로 인공심폐기의 사용없이 박동상태에서 내유동맥으로 좌전행지관상동맥에 우회술을 실시하였는데, 그 중 1례는 내유동맥의 비꼬임으로 술 후 1주일 째 재수술한 경우였다. 흉골우연종절개는 1례로 승모판교련절개술 후 재발된 협착증에 대해 승모판치환술을 실시한 경우였다. 소흉골절개선으로 수술한 예는 21례로, 승모판치환 및 삼첨판성형술이 6례, 승모판치환술 5례, 중복판치환술 2례, 대동맥판치환술 1례, 좌심방점액종 1례, 심방중격결손증 2례, 심실중격결손증 2례, 우심실 자창 1례였다. 처음 5례는 T형의 흉골소절개를 실시하였으나 경험이 쌓이면서 대동맥기저부의 노출이 좋고 흉골 봉합시 안정감이 높은 화살모양의 흉골소절개를 실시하였다. 결과: 수술시간, 인공심폐 구동시간, 대동맥차단시간, 인공호흡기 사용기간, 수술 1일까지의 흉관배액양, 흉관 거치기간, 집중치료실 입원기간 등은 기존의 정중흉골절개선 예들에 비하여 큰 차이가 없었다. 수술 후 사망 예는 2례였으며 1례는 흉골소절개선으로 승모판치환 수술 1일에 대동맥 삽관부위의 파열로 출혈 사망하였고, 다른 1례는 흉골좌연종절개선으로 관상동맥우회술 후 2일에 부정맥으로 사망하였다. 사망의 원인과 수술절개선의 선택과는 직접적인 관련이 없었다. 합병증은 뇌색전증 1례, 창상의 혈종 1 례가 있었다. 결론: 소절개선으로도 정중흉골절개선과 마찬가지로 심장 수술을 효과적으로 실시할 수 있을 것으로 생각된다. Background: Minimally invasive technique for various cardiac surgeries has become widely accepted since it has been proven to have distinct advantages for the patients. We describe here the results of our experiences of minimal incision in cardiac surgery. Material and Method: From February 1997 to November 1998, we successfully performed 31 cases of minimally invasive cardiac surgery. Male and female ratio was 17:14, and the patients age ranged from 1 to 75 years. A left parasternal incision was used in 9 patients with single vessel coronary heart disease. A direct coronary bypass grafting was done under the condition of the beating heart without cardiopulmonary bypass support(MIDCAB). Among these, one was a case of a reoperation 1 week after the first operation due to a kinked mammary artery graft. A right parasternal incision was used in one case of a redo mitral valve replacement. Mini-sternotomy was used in the remaining 21 patients. The procedures were mitral valve replacement and tricuspid annuloplasty in 6 patients, mitral valve replacement 5, double valve replacement 2, aortic valve replacement 1, removal of left atrial myxoma 1, closure of atrial septal defect 2, repair of ventricular septal defect 2, and primary closure of r ght ventricular stab wound 1. The initial 5 cases underwent a T-shaped mini-sternotomy, however, we adopted an arrow-shaped ministernotomy in the remaining cases because it provided better exposure of the aortic root and stability of the sternum after a sternal wiring. Result: The operation time, the cardiopulmonary bypass time, the aorta cross-clamping time, the mechanical ventilation time, the amount of chest tube drainage until POD#1, the chest tube indwelling time, and the duration of intensive care unit staying were in an acceptable range. There were two surgical mortalities. One was due to a rupture of the aorta cannulation site after double valve replacement on POD#1 in the mini-sternotomy case, and the other was due to a sudden ventricular arrhythmia after MIDCAB on POD#2 in the parasternal incision case. Postoperative complications were observed in 2 cases in which a cerebral embolism developed on POD#2 after a mini-sternotomy in mitral valve replacement and wound hematoma developed after a right parasternal incision in a single coronary bypass grafting. Neither mortality nor complication was directly related to the incision technique itself. Conclusion: Minimally invasive surgery using parasternal or mini-sternotomy incision can be used in cardiac surgeries since it is as safe as the standard full sternotomy incisions.

경사증착법을 이용한 PM-OLED용 무기박막형 보호층 연구

김광호,김훈,김재경,도이미,한정인,주병권,Kim, Kwang-Ho,Kim, Hoon,Kim, Jae-Kyung,Do, Lee-Mi,Han, Jeong-In,Ju, Byeong-Kwon 한국전기전자재료학회 2003 전기전자재료학회논문지 Vol.16 No.9

In this study, the MgO thin-film passivation layer was adopted to protect passive matrix organic light emitting diode(PMOLED) with the cathode separator from moisture and oxygen. Using the substrate rotate and tilt technique during the deposition, the organic and cathode layers were perfectly covered with MgO. And then, we analyzed the difference of the current-voltage and luminescence characteristics between passivated OLED of the MgO and non-passivated OLED. It was found that the number of dark spot generated from the degradated pixel was decreased owing to the Mgo thin-film passivation layer using the tilt & rotate technique. And the half-life time passivated OLED was improved two times more. Thus, the MgO could be vaccum-deposited under the low temperature and had a merit that the organic layer was not much affected. We can consider that MgO thin film passivation method can be adopted to protect the OLED from moisture and oxygen and can offer the enhancement of lifetime.

후측개흉술과 근육보존수직개흉술의 임상고찰

김광호,김현태,김정택,선경,Kim, Kwang-Ho,Kim, Hyun-Tae,Kim, Jung-Taek,Sun, Kyung 대한흉부심장혈관외과학회 1998 Journal of Chest Surgery (J Chest Surg) Vol.31 No.5

후측개흉술은 흉근을 절단하는 단점은 있으나 훌륭한 수술시야를 제공하므로 표준개흉술로 이용되고 있다. 이에 반하여 근육보존수직개흉술은 흉근이 보존되며 팔을 내리면 액와부 수술 상흔이 감추어지는 미용상의 장점이 있다. 그러나 수직개흉술은 흉부의 정측면에 절개선이 이루어지므로 측와위에서 수직으로 수술시야를 내려다보게 되어 흉강내의 구조물, 특히 폐문부나 첨부 및 하부의 길이가 멀어져 수술조작이 불편하다. 본 인하대병원 흉부외과에서는 수술조작에 관련된 차이를 알아보고자 후측개흉술(15례)과 수직개흉술(14례)을 이용해 폐쐐기절제술 이상의 수술을 실시한 29례에서 수술과 관련된 임상지표들을 비교관찰한 결과, 수술시간, 수술 1일과 2일의 흉관 배액량, 흉관 거치기간, 수혈 수와 수혈량, 수술 중 실혈량, 수술 후 합병증 등에서 양군간에 차이가 없었다. 이상의 결과를 볼 때 근육보존수직개흉술도 후측개흉술과 마찬가지로 폐절제술시 안전하게 사용될 수 있다고 본다. Although posterolateral thoracotomy(PLT) has been a standard thoracic incision in resection surgery of the lung for surgeons to achieve a good surgical field, there remains concern about severing a group of thoracic muscles remains. Muscle-sparing vertical thoracotomy (MVT) is an alternative to PLT, which gives cosmetic result and may preserve motion of the shoulder girdle as well as respiratory function of the patient in the early postoperative period. However, surgeons tend not to perfer it because of limited surgical field from the vertical wound made on the lateral thoracic wall. The purpose of this study is to compare the surgical outcomes of PLT versus MVT. We retrospectively reviewed 29 patients(15 who had PLT and 14 who had MVT, organized into those two groups) who had undergone lung resection surgery in our institute. There were no clinical differences between the two groups in terms of operation time, estimated amount of blood loss during the operation, amount of chest drainage on the first and the second postoperative day, duration of chest tube placement, incidence and amount of transfusion, and postoperative complications. We conclude that, from our limited experience, MVT can be applied to lung resection surgery as safely as PLT and that it may have a beneficial role for the patient with compromised lung function in addition to cosmetic effect.

It is thought that Kim Hong-kyeong followed the existing theory of Meridian(經絡) and supplemented his unique perspectives in interpreting it. And he tried to relate Meridian with hygiene of mind. I took up with the research on the assumption that the review of Kim's method can present new perspectives to the study of relationship between Meridian and hygiene of mind. The results of my study are as follows: 1. Kim followed common theory of Meridian and then added his unique perspectives to it. His method of interpretation has one characteristic. By introducing Idealism(唯心論), he understood 'Meridian' as the path of the mind and the emotion. Especially I think his hypothesis that acupuncture can be widely used in mental diseases as well as body related diseases and its applications to treatment are very valuable. 2. Meridian and hygiene of mind are close together. I think Kim's unique trial is something new in studying relationship between Meridian and hygiene of mind but requires more research on it.

외국인소유와 직장 내 여성차별

김광호,Kyoung Yong Kim 한국국제경영학회 2017 國際經營硏究 Vol.28 No.3

직장 내 성차별은 많은 나라에서 아직도 큰 사회적 이슈이고 전 세계적으로 국제기관과 각국 정 부들은 이를 줄이기 위해 많은 노력을 기울이고 있다. 기업들 또한 직장 내 성차별을 줄이는 것을 사회적 책임 활동의 하나로 여기고 점차 많은 관심을 보이고 있다. 이러한 추세를 바탕으로 본 연 구는 외국인 소유가 직장 내 여성차별에 어떠한 영향을 미치는지를 조사한다. 한국직업능력개발원 에서 구축한 인적자본 기업패널 자료를 분석하여 본 연구는 외국인이 소유권을 보유하고 있는 회사 는 한국인만이 소유권을 보유하고 있는 회사에 비해 좀 더 많은 여성 인력을 채용하고 있음을 밝혔 다. 또한 외국인이 소유권을 보유하고 있는 회사는 상장회사일 경우 비상장회사에 비해 정규직 여 성채용에 더 적극적임을 발견했다. 이러한 연구결과는 외국인 투자가 현지국의 직장 내 성차별이라 는 사회적 이슈에 미치는 영향을 보여줌으로 외국인 투자와 성차별에 관한 연구분야에 유용한 시사 점을 제공하고 있다. This study explores how foreign ownership influences gender inequality at the workplace by examining the case of Korea. By analyzing Human Capital Corporate Panel dataset from Korea, this study found foreign ownership is likely to hire more women compared to local ownership. This study also revealed that foreign ownership tends to offer more regular positions to women when it is a public firm which is more sensitive to stakeholder pressures and exposed to diverse stakeholders than private firm. We hope that our study contributes to the existing literature on foreign investment and gender inequality at the workplace by demonstrating the relationship between foreign ownership and gender inequality at the workplace. Thus, we expect that this study stimulates future research on the role of foreign actors in improving social issues.

The presence of left atrial thrombus in mitral stenosis has been reported to be associated with several factors. These are age, sex, presence of atrial fibrillation, episodes of congestave heart failure, calcification of mitral valve, embolic episode, etc. Since none of these single factor has been always related to the presence of left atrial thrombus, related risk factors to left atrial thrombosis were studied in patients with mitral stenosis using chi square test. We had operated on 191 cases of mitral valvular heart disease from Jan. 1978 to June 1981 at Severance Hospital, Yunsei University College of Medicine. The left atrial thrombi were present in 41 cases among 191 cases of mitral valvular heart disease and it was present in 31 cases among 89 cases of pure mitral stenosis. Only 10 cases among 74 cases of mitral stenoregurgitation had left atrlal thrombi, whereas no left atrlal thrombus was found in patients with pure mitral regurgitation. Related risk factors studied herein were sex, episodes of congestive heart failure, atrial fibrillation, pulmonary capillary wedge pressure, mitral valve area calculated by Gorlin and Gorlin`s formula cardiac output and left atrial dimension by echocardiogram. In this study presence of atrial fibrillation was deemed to be one of the most potential risk factors and other factors of age, duration of symptoms, episode of embolization, calclfication of mitral valve, associated aortic and tricuspid valve disease, ejection fraction of left ventricle by cineangiocardiogram and echocardiogram were not significantly related to the presence of left atrlal thrombi in a statistical viewpoint.

김광호,양계진,Kwang-Ho Kim 한국작물학회 1987 한국작물학회지 Vol.32 No.1

Fifty eight isolates of R. solani collected from rice plants infected to sheath blight disease at seven different locations through the country were evaluated for their cultural characteristics on media. Degree of resistance of nine rice varieties were tested by the seven isolates representing each culture type from the grouped pathogene-city. Great variation of cultural characterisics on PSA media was observed among isolates, and 58 isolates tested were grouped into 7 culture types. Locational distribution of isolates belong to each culture type was different between types, and only isolate type 'Ia' was distributed in all locations collected. The degree of pathogene-city of each isolate to rice adult plant was different between 7 culture types grouped, and no isolates infected severely on all tester rice varieties. The degree of resistance to the disease showed great variation among 9 tester varieties, and varietal reaction to the disease was varied along with isolates inoculated. An isolate, la, shown strong pathogenecity and distributed through 7 locations was selected for the screening of varietal resistance to rice sheath blight disease. 벼 품종의 잎집무늬마름병 저항성검정에 사용할 R. solani 균주를 선발할 목적으로 전국 7개지역에서 수집한 58개균주의 배양특성을 조사하여 균주의 배양형을 나누고 각 배양형에서 대표되는 균주를 선정, 9개 벼 품종에 접종시켜 균주의 병원성과 품종저항성을 조사한 결과를 요약하면 다음과 같다. 1. 벼 잎집무늬 마름병균의 균주를 PSA 배지상에서 기르면서 조사한 5종류의 배양특성은 균주간에 뚜렷한 차이가 있었으며 균주별 배양특성에 근거하여 공시한 58개 균주를 7종의 배양형으로 나눌 수 있었다. 2. 각 배양형에 속하는 잎집무늬마름병균 균주의 지역적인 분포는 차이가 있어서 균주분포의 지역특이성이 인정되었으며 Ia 배양형에 속하는 균주만이 7개 지역 모두에 분포되어 있었다. 3. 각 배양형을 대표하는 7개 균주의 병원성은 서로 달랐으며 균주별 병원성은 검정품종에 따라서 그 정도가 다르게 나타났다. 4. 균주의 병원성검정에 사용되었던 9개 벼 품종의 저항성정도도 품종간 차이가 켰으며 품종의 저항성 반응도 접종한 균주에 따라서 달리 나타나는 경우가 있었다. 5. 공시한 균주의 병원성정도와 지역적인 분포범위를 고려하여 벼 잎집무늬마름병 저항성검정에 사용할 균주를 선발할 수 있었다.

NiO를 첨가한 WO₃ 박막의 미세 구조 거동

Thin films of tungsten oxide and nickel oxide were deposited on $Al_2O_3/Si-substrate$ by high vacuum thermal evaporation. The properties of microstructure and crystallinity were analyzed by SEM and XRD respectively. $WO_3$ films without addition of NiO showed polycrystalline structure after annealing at $500^{\circ}C$ for SO min. There were the cracks between the polycrystalline grains and the crack width was increased with the thickness of $WO_3$ films. The cracks in the $WO_3$ films could be controlled by an optimum deposition of NiO on $WO_3$ films and either less or more than the optimum addition fails to suppress the cracks. A process mechanism to suppress the crack has been discussed.
