Organic forage production system is one of the most important aspects in organic livestock production. Animals in the organic farming system are also essential for manure to be used for organic forage production. Both organic forage and animals are essential to maintain the cycle of organic agriculture system. In this paper we introduce the organic forage production system in Korea. Summer and winter crops are getting popular in Korea because of their high forage yield and cultivation in double cropping systems. Common cropping system for forage production in Korea is the double cropping system with legume and grass mixture. Forage sorghum and sudangrass are the most popular ones of annual summer forage corps because of their high production with low cost in the double cropping systems. In the mixture of forage crops, inter cropping is more suitable in the corn and sorghum cropping system because of high lodging resistance and forage yield, and low weed population. Forage sorghum and sudangrass are difficult to preserve as direct-cut silage due to the fact that its high moisture content causes excessive fermentation during ensiling. Corn grain addition to sorghum silage could be recommended as the most effective treatment for increasing quality and reducing production cost. It is recommended that corn grain could be added up to 10% of total amount of silage. And agriculture by-products also can be added at the time of ensiling to minimize losses of effluent and have the additional advantage of increasing quality. Agriculture by-products as silage supplements increased DM content and quality, and decreased the production cost of sorghum silage. Field pre-wilting treatment of forage crops also increased DM content and quality of the silage. Wilting sorghum${\times}$sudangrass hybrid before ensiling was the effective method for reducing effluent and increasing pH and forage quality more than direct cut silage. Optimum prewilting period of sudangrass silage was 1 or 2 days. In organic forage, the most important factor is the enhancement of organic forage sufficiency in relation to the environmental-friendly and organic livestock. Consequently, there are many possibilities for animal production and organic forage production in Korea. No forages no cattle concept should be emphasized in organic farming system.

김종덕,최성열,김동수,김기환,Kim, Jong Deok,Choi, Seong Yeol,Kim, Dong Soo,Kim, Ki Hwan 대한소아감염학회 2013 Pediatric Infection and Vaccine Vol.20 No.1

비장티푸스성 살모넬라균은 그람 음성 간균으로, 인체감염 시 위장관염부터 발열, 균혈증 등의 전신성 증상을 보일 수 있다. 이들의 감염은 주로 음식물을 매개로 이루어지나 애완용 파충류, 양서류, 어류 등을 통한 전파 역시 가능한 것으로 알려져 있다. 하지만 알려진 바에 비해 국내에서 애완용 파충류 및 어류를 통한 살모넬라 감염의 보고는 없는 상황이다. 이에 저자들은 세브란스병원에 발열을 주소로 내원하여 살모넬라 균혈증을 진단받은 2명의 환아를 조사하여 이들의 병력 상 애완용 거북이 및 열대어와의 접촉을 통한 살모넬라 감염의 가능성이 있음을 확인하였다. 최근 애완용 파충류 및 어류의 사육이 증가하고 있는 상황에서 살모넬라 감염을 예방하기 위한 노력이 필요하며, 특히 살모넬라 감염에 의하여 심각한 합병증을 유발할 위험성이 높은 5세 미만의 소아에서는 애완용 파충류 및 어류와의 접촉이 이루어지지 않도록 하는 것이 중요할 것으로 판단되어 이를 증례를 통하여 보고한다. Nontyphoidal Salmonella are gram negative bacilli organism, which may induce systemic infection such as febrile enteritis, bacteremia, and osteomyelitis. Main route of infection is known as food but also possible through reptile, amphibian, and fish raised as pets in the house. There is no known cases report of Salmonella infection through pets in Korea and also rare in the overseas. We report 2 patients who visited Severance children's hospital with chief complaint of fever and diagnosed as nontyphoidal salmonellosis. Each case had a history of raising turtle or tropical fish with possibility of Salmonella infection through these pets. Increasing incidence of raising pet reptile and fish lately, contact precaution and proper prevention and control of Salmonella infection of these pets especially in children under 5 years old are necessary due to higher risk of serious complications of salmonellosis.

김종덕,지현근,신제균,김준석,이송암,김요한,김혜영,이우성 대한흉부외과학회 2014 Journal of Chest Surgery (J Chest Surg) Vol.47 No.3

Background: Open heart surgery using cardiopulmonary bypass (CPB) is considered one of the most frequent surgical procedures in which acute kidney injury (AKI) is a frequent and serious complication. The aim of the present study was to evaluate the efficiency of neutrophil gelatinase-associated lipocalin (NGAL) as an early AKI biomarker after CPB in cardiac surgery (CS). Methods: Thirty-seven adult patients undergoing CS with CPB were included in this retrospective study. They had normal preoperative renal function, as assessed by the creatinine (Cr) level, NGAL level, and estimated glomerular filtration rate. Serial evaluation of serum NGAL and Cr levels was performed before, immediately after, and 24 hours after the operation. Patients were divided into two groups: those who showed normal immediate postoperative serum NGAL levels (group A, n=30) and those who showed elevated immediate postoperative serum NGAL levels (group B, n=7). Statistical analysis was performed using Statistical Package for the Social Sciences version 18. Results: Of the 37 patients, 6 (6/37, 16.2%) were diagnosed with AKI. One patient belonged to group A (1/30, 3.3%), and 5 patients belonged to group B (5/7, 71.4%). Two patients in group B (2/7, 28.5%) required further renal replacement therapy. Death occurred in only 1 patient (1/37, 2.7%), who belonged to group B. Conclusion: The results of this study suggest that postoperative plasma NGAL levels can be used as an early biomarker for the detection of AKI following CS using CPB. Further studies with a larger sample size are needed to confirm our results.

김종덕,김준석,황태석,송명근,신제균 대한흉부외과학회 2014 Journal of Chest Surgery (J Chest Surg) Vol.47 No.1

Leiomyosarcoma may occur anywhere in the body but rarely occurs in the heart or great vessels. Leiomyosarcoma may be managed by surgical resection with or without chemotherapy or radiotherapy. Owing to the high rate of metastasis and poor prognosis, a definitive treatment modality for leiomyosarcoma has not yet been suggested. This case study reports the surgical management of the recurrent leiomyosarcoma of the heart and the great vessels in a 63-year-old woman.

택견의 ‘제기차기’를 통해서 본한국전통춤의 하체움직임 효율성 연구

김종덕 한양대학교 우리춤연구소 2011 우리춤과 과학기술 Vol.7 No.1

이제까지의 전통춤에 관한 연구는 무용의 사회학적, 인류학적 배경 등을 통한 춤사위 연구가 대부분이었으며, 춤 동작이 움직임의 원리로써 중요성이나 연계성, 오류 등을 지적한 연구가 미비하였다. 전통춤은 도제식 교육으로 정확한 움직임의 구조를 논리적으로 이해하지 못한 상태에서 지도자의 동작을 문제의식 없이 수용하고 잘못된 동작에 대한 체계적인 수정이 이루어지지 못한 것이 사실이다. 본 논문의 연구목적은 택견의 제기차기를 통하여 전통춤(처용무와 탈춤)에서 보여지는 하체 움직임의 오류를 바로잡아 하체 움직임의 중요성을 고취시키고 사라져가고 있는 남성춤의 선비다운 면모를 회복하기 위함이다. So far, most studies on the Korean traditional dance have focused on dancing motions in view of its sociological and anthropological backgrounds, and there have been few studies pointing out the importance, the linkage or the error of dancing motions based on principles of motion. In fact, the Korean traditional dance is instructed through the apprentice education system with no logical understanding of the structure of correct motions, and thus, a master’s motions are learned with no critical mind, and wrong motions fail to be corrected systematically. This study is to correct errors of the lower body motion viewed in the Korean traditional dance (Cheoyong Dance and Mask Dance) so that the importance of the lower body motion may be more emphasized and features of a learned man contained in the masculine dance, which are disappearing, may be restored.

세계화 이후 일본사회의 가치관 변화

김종덕 한국외국어대학교 국제지역연구센터 2005 국제지역연구 Vol.9 No.2

1980년대 중반 이후, 이데올로기적인 담론의 약화와 냉전 체제의 붕괴, WTO의 출범, 정보통신의 혁명으로 비롯된 세계화의 물결은 세계 기존 질서의 변화를 가져왔다. 본고에서는 이와 같은 세계화 현상에 따라 일본의 전통적인 가치관에 어떤 변화가 생겼고, 일본의 역할과 전망은 무엇인가를 살펴보고자 하였다. 근대 초기 제국주의와 군국주의를 지향하여 근대화에 성공한 일본은 2차대전의 패전에도 불구하고 전통적인 가치관을 강조하며 경제대국을 이룸으로써 아시아 중심 국가로서의 위상을 확립하는데 성공하였다. 그러나 이는 일본 사회의 폐쇄성에 대한 부정적인 인식과 비판을 수반하였다. 1990년대 이후 경기침체와 중국의 부상 등으로 자국의 위상에 위기감세계화 이후 일본사회의 가치관 변화* 김 종 덕**을 느낀 일본은 경제대국으로서의 위상을 유지할 뿐만 아니라 나아가 명실상부한 세계의 중심 국가로 발돋움하기 위해 세계화에 국력을 집중하고 있다. 그리고 그 방안의 하나로서 영어 교육의 강화를 통한 국제 커뮤니케이션 능력 함양과 외국인에 대한 일본어 교육의 확산 등을 통한 일본 문화의 수출에도 주목하고 있다. 이는 일본이 이제까지의 경제대국으로서의 위상에 만족하지 않고 보다 다양한 방면에서 세계의 중심 국가의 역할을 하고자 하는 시도라 하겠다. Since the mid 1980's, globalization caused by the decline of ideological dispute, the collapse of Cold War systems, the starting of WTO and the revolution of information and communication technology has brought the changes in world-wide existing order. So, in this context, this study tries to observe what kind of changes occurred in traditional Japanese social values and what the role and perspective of Japan would be like. Japan has been successful in establishing itself as a world economic superpower with emphasis on its traditional values since the early modern era. However, this was accompanied with negative recognition and criticism of the exclusiveness of Japanese society which was deemed not good for a major economic power. Since the 1990's, Japan, feeling a sense of crisis in phase of its own country by economic stagnation and the rise of China, has been concentrating its national power on globalization not only for maintaining phase as a major economic power but also for stretching itself as a leading nation of the world both in name and in reality. Furthermore it deserves special mention that Japan has been bringing up the international communication ability of the nation by strengthening the level of English language education of its people and has been paying attention to the export of Japanase culture by providing Japanese language education for foreigners. This is a trial that Japan, not having been satisfied with phase as a conventional major economic power in Asia, is going to play in their role as a world-leading nation in various areas.
