This article is about the cartohistorical value and significance of the 『Joseon-jido. 朝鮮地圖, Map of Korea』, the copy of the 『Dongguk-daejeondo, 東國大全圖 Great map of Korea.』 by Jeong Sang-Gi(鄭尙驥), which is the collection of the National Museum of Korea. The conclusions are as follows. First, by the contents of the map, it is presumed that the map was made between the years 1757-1767. Therefore, it is easy to assume that the map was made in 1740s. Among the others, the map was made in the earliest days. Second, the 『Joseon-jido』 was drawn on the fine silk with the delicate lines, and the map has rvtanchuria of China and Japan, which were presumed to be included in the original map. Also, comparing the copies of 『Paldo-bundo, 八道分圖 Maps of Eight Provinces』 by Jeong to the map by trigonometry calculation, we can presume that both of the map were made by the same scale. By these reasons, the 『Joseon-jido』 is presumed to be the Dongguk-daejeondo in 『YoungJo Sillok, Annals ofKing YoungJo』, which Jeong Hang-Ryung(鄭恒齡). son of Jeong Sang-Gi(鄭尙驥). brought from home and copied it to provide the map to the HongMoonKwan(弘文館, Office of Special Advisers) in 1957(33th year of King YoungJo) Third, there are over 2200 place names mentioned in the 『Joseon-jido』, and these names are also mentioned in the Dongguk-daejeondo and the Paldo-bundo. Most of the place names of the natural features were that of the mountains. and the name of the hills were mentioned in detail. Most of the place names of the civil features were that of the military facilities, such as military camps and the mountain castles. Therefore. it can be said that the map had administrative and military purpose. Fourth, the expression of the landscape followed the classic mountain range-centered understanding while at the same time stressing the six Jeongmaks(正脈, Secondary Mountain Range), the important military defence line. The traffic route was expressed in detail among the other civil features, and the mountain castles. military camps and the signal fire were also expressed in detail with the more symbolized marks. Fifth, unlike the existed articles. the map expressed the changes in the military camps, mountain castles, traffic routes, stations and the signal fires.

본 연구에서는 배의 유용성 증명을 위한 일환으로 배의 화학성분을 분자수준에서 밝히고자 하였다. 이에 배 과피 MeOH 추출물을 용매분획하여 얻은 EtOAc-산성 분획과 EtOAc-중성분획을 대상으로 Sephadex LH-20, silica gel, 그리고 ODS colmn chromatography와 HPLC를 이용하여 정제 및 단리하였다. 그 결과, EtOAc-산성 분획과 EtOAc-중성 분획으로부터 각각 2종씩의 화합물을 단리하였다. 단리된 화합물 1-4는 1H- 및 13C-NMR 분석을 통하여 각각 (S)-(+)-2-cis-abscisic acid O-β-D-glucopyranosyl ester (화합물 1), 1-[4-O-β-D-glucopyranosyl]phenyl ethanone(piceoside, 화합물 2), β-sitosterol (화합물 3), 그리고 β-sitosteryl 3-O-β-D-glucopyranoside (화합물 4)로 동정되었다. 단리된 3종의 배당체 화합물(화합물 1, 2, 4)들은 본 연구에 의해 배로부터 처음 동정되었으며, 화합물 3은 추황배로부터 처음 동정되었다. 본 연구결과가 배 함유 성분연구는 물론 배의 기능성 해명 연구에도 추후 중요한 기초자료로 활용되길 기대한다. We isolated and identified antioxidants from acidic and neutral ethyl acetate fractions of the peel of pear (Pyrus pyrifolia N. cv. Chuhwangbae). We isolated 4 compounds from the methanol extract, by using 3 different types of column chromatography (Sephadex LH-20, silica gel, and octadecylsilane) and preparative HPLC. We identified the isolated compounds as (S)-(+)-2-cis-abscisic acid O-β-D-glucopyranosyl ester (compound 1), 1-[4-O-β-D-glucopyranosyl]phenyl ethanone (picroside, compound 2), β-sitosterol (compound 3), and β-sitosteryl 3-O-β-D-glucopyranoside (compound 4) by nuclear magnetic resonance analysis. We are the first to report the identification of compounds 1, 2, and 4 from pear.

정대성,김승주,이진헌,최재학,이주,Jung, Dae-Sung,Kim, Seung-Ju,Lee, Jin-Hun,Choi, Jae-Hak,Lee, Ju 한국조명전기설비학회 2007 조명·전기설비학회논문지 Vol.21 No.3

가전분야에서의 전동기 효율향상을 통한 에너지 소비절감 효과는 상당히 크지만 이를 위한 전동기의 설계/해석 기술 확보가 아직은 미흡한 상태이다. 이에 따라 유도형 동기전동기가 제안되었지만, 유도형 동기 전동기는 유도전동기와 통기전동기의 특성을 동시에 가지고 있어, 해석 및 설계가 쉽지 않다. 따라서 본 논문에서는 기존의 냉장고 압축기용 전동기인 단상유도전동기를 대처할 수 있는 단상 유도형 동기전동기를 이용해 파라미터에 따라 특성이 어떻게 바뀌는가에 대해 서술하였다. 그에 따라 단상유도전동기의 정상상태 특성을 해석하고 제안모델의 성능을 기존모델과 비교하고 실험하여 해석결과의 신뢰성을 검증한다. 또한 본 논문에서는 제안모델의 기존 고정자 형상이나 권선 스팩을 유지하고 회전자의 형상이나 구조만을 변경시켜 성능향상을 도모하였다. 해석방법으로는 전자장 수치 해석적인 방법으로 널리 이용되고 있는 유한요소법(Finite Element Method : FEM)을 이용하였다. Electric motor efficient improvement from home appliance field is important to the effect reducing the energy consumption. But the electric motor design/analysis technology is still insufficient. Specially the electric motor design/analysis technology of satisfying characteristic of both the induction motor and the synchronous motor such as Line start permanent motor. Therefore the electric motor design/analysis technology is urgently demanded reliability. This paper proposes the sing1e-phase line-start permanent magnet motor to develop the motor it with be able to alternate the sing-phase induction motor it is a refrigerator compressor motor. The sing-phase induction motor is analyzed in the steady state. And we have a certification test to compare our single-phase line-start permanent magnet motor with the sing-phase induction motor. In order to improve the performance, the stator of the single-phase line-start permanent magnet motor is same as the stator of the sing-phase induction motor and changes the rotor form and has the permanent magnet. It used the Finite Element Method(FEM) which is widely used with electronic-magnetic field numerical analysis method.

초등 교과교육학의 성격과 내용구조 연구

유한구(Han Ku Ryu),장성모(Sung Mo Chang),송광용(Kwang Yong Song),조주연(Joo Yun Cho),이학주(Hak Ju Lee) 한국초등교육학회 1997 초등교육연구 Vol.11 No.1

이 연구는 교과교육과 교과교육학의관계, 그리고 교과교육학과 교육학의 관계등을 분석하고, 그 결과를 토대로 하여 초등학교 교과교육과 교육대학 교과교육학 교육의 실제를 정확히 이해하고 그 발전 방향을 탐색하기 위한 것이다. 일반적으로, 교과교육학은 교육학에서 제시하고 있는 교육과정의 구성및 교육방법상의 일반 원리를 교과교육이라는 특수한 사태에 적용하는 과정에 관심을 두는 이론으로 간주되고 있다. 이 관점에 의하면, 교과교육학은 교육학의 일반적 원리에 따라 교과교육이라는 특수한 맥락에 처방을 내리기 위한 것으로 파악된다. 이 관점을 교과와 그것을 가르치는 교사의 삶을 사실상 별개의 것으로 분리하는 것이며, 그와 동일한 이유에서 교과교육학과 교과교육학자의 삶 또한 별개의 것임을 전제하는 것이다. 그러나 교과교육과 교과교육학, 그리고 교과교육학과 교육학의 관계는 이론에서 실제로 나아가는 앞의 방향과는 정반대 방향에서도 이해될 수 있다. 이 관점에 의하면, 교과교육학은 교과교육 실제에 처방을 내리기 위한 것이 아니라 그 실제를 기술하고 정당화하기 위한 것으로 파악된다. 교과교육과 교과교육학의 관련이 이렇게 파악될 때, 교과 교육학은 교사나 교과교육학자에게 자신이 지금 하는 일이 자신의 삶과 결코 무관한 것이 아니라는 믿음을 심어 주게 되며, 나아가 그들 자신이 참여하고 있는 초등학교나 교육대학의 교육실제를 기술하거나 정당화하려고 할 때 반드시 필요한 개념적 도구를 제공해 줄 수 있게 된다. 바로 여기에 교과교육학에 관한 종래의 접근과는 구분되는 새로운 접근방식이 요구되는 이유가 있다. The purpose of this study is threefold: The first is to analyse the relations between subject education and subject pedagogy, and between subject pedagogy and general pedagogy. The second is, based on the analysis result, to have the precise understanding of teaching various subjects in the elementary school, and of teaching subject pedagogy in the university of education. The third is to search for the desirable direction of developing the elementary education and the teacher education. Subject pedagogy is usually defined as a theory which is interested in the process of applying pedagogical principles regarding curriculum organization and teaching methods to specific teaching situations, that is, subject education situations. However, this definition has a limitation, because it assumes that a subject and the teacher's life who teaches the subject are separated from each other, and that subject pedagogy and the scholar who studies subject pedagogy are also separated. The relationship between subject teaching and subject pedagogy, and between subject pedagogy and general pedagogy can be understood with quite different viewpoint. This new viewpoint, which is the major discussion matter of this study, assumes that subject pedagogy is never separated from the life of subject teacher/subject pedagogist. This viewpoint will reveal the theoretical features of subject pedagogy better, and give us new meaning on the life of teachers/subject pedagogists. The subject pedagogy in the correct sense should provide teachers/pedagogists with the conceptual instrument based on the new viewpoint. This conceptual instrument will make teachers/pedagogists be able to describe, explain, and validate their own educational practice-such as the content structure of each subject-in the elementary school or the university of education.

배 경 편평상피암은 두경부의 악성종양 중 가장 흔하며, 임상적인 경과가 불량하다. 따라서 나쁜 예후를 가지는 환자군을 조기에 선별하여 더 적극적인 치료의 시행을 결정짓는 표지자의 필요성이 대두된다. 우리는 일련의 두경부 편평 세포암 검체에서 몇몇 분자 표지자의 예후적 유용성을 평가하고자 하였다. 방 법 23예의 두경부 편평세포암 검체를 대상으로 VEGF, p53, Apaf-1, caspase-9의 발현과 몇몇 임상병리학적 지표들간의 연관성을 면역조직화학염색을 통해 조사하였다. 결 과 환자군은 남성이 더 많았으며 평균연령은 63.7세였다. 1기가 5예, 2기가 2예, 3기가 8예, 4기가 8예였다. 평균생존기간은 37.3개월이었다. VEGF단백 발현은 종양의 크기와 통계적으로 유의한 연관성을 보였다. 이와 더불어 VEGF 단백 발현은 병기, 그리고 림프관 침습과 연관적인 경향성을 보였다. 그러나 VEGF단백 발현과 생존기간과는 관련성이 없었다. 또한, Apaf-1과 caspase-9의 단백발현은 다른 임상지표, 환자의 생존기간과는 관련이 없었다. 결 론 VEGF단백 발현은 두경부 편평세포암 환자에서 나쁜 임상경과를 예측할 수 있게 하는 표지자로서의 역할을 할 수 있다. 또한 본 연구는 두경부 편평세포암에서 별로 연구되지 않은 Apaf-1과 caspase-9의 발현상태를 밝힌 점에서 의의가 있다.

Lee, Kyong Joo,Jung, Yun Sook,Lee, Chan Joo,Wi, Jin,Shin, Sanghoon,Kim, Taehoon,Lee, Sang Hak,Kang, Seok-Min,Lee, Moon-Hyoung,Park, Han Ki Yonsei University College of Medicine 2009 Yonsei medical journal Vol.50 No.4

<P>Sinus node dysfunction occurs occasionally after heart transplantation and may be caused by surgical trauma, ischemia to the sinus node, rejection, drug therapy, and increasing donor age. However, the timing and indication of permanent pacemaker insertion due to sinus node dysfunction following heart transplantation is contentious. Here, we report a case of a permanent pacemaker insertion for syncope due to sinus arrest after heart transplantation, even with a bicaval technique, which has been known to associate with few incidences of sinus node dysfunction.</P>

Proximate Chemical Composition and Endogenous Gibberellins of Chufa (Cyperus esculentus L.) in Upland and Wetland

Sang-Kuk Kim,Hong-Jib Choi,Sang-Mo Kang,In-Jung Lee,Hak-Yoon Kim 韓國作物學會 2011 Korean journal of crop science Vol.56 No.1

Proximate chemical components (protein, oil, carbohydrate, ash, fiber, and starch) were determined from tubers grown in upland and wetland conditions. The contents of crude protein, oil, carbohydrate, and starch were higher in upland condition than in wetland condition. Eight gibberellins were commonly identified and quantified in leaves and tuber of chufa grown in wetland and upland field during growing season. Gibberellin content was always higher specifically in the leaves and tubers grown in wetland condition than in those grown in upland condition. The current knowledge of gibberellin biosynthesis suggests that the two endogenous bio-active gibberellins both GA1 and GA4 are differently metabolized according to cultural conditions. Major gibberellin biosynthesis route is ascertained dominantly the non C-13 hydroxylation pathway leading GA4 in chufa plants.

( Hak Tae Kim ),( Young Jae Kim ),( Woo Jin Lee ),( Chong Hyun Won ),( Sung Eun Chang ),( Jee Ho Choi ),( Mi Woo Lee ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.1

We report a case of a 69-year-old man with metastatic cutaneous duodenal gastrointestinal stromal tumor, which led to find multiple metastases on orbital muscle and scalp. The patient presented with a rapidly growing chest nodule with mild tenderness. He underwent surgical resection for duodenal gastrointestinal stromal tumor and had been treated with imatinib for three years. Histopathological examination of the chest nodule was consistent with gastrointestinal stromal tumor. A brain magnetic resonance imaging of follow work-up revealed multiple metastases at the left superior rectus muscle and occipital scalp. Under the diagnosis with imatinib-resistant duodenal gastrointestinal stromal tumors, a second-line therapy with sunitinib was tried. After six weeks, all skin lesions were completely improved and other metastatic cancers showed a response of stable disease to sunitinib therapy. This is the first reported case of metastatic cutaneous duodenal gastrointestinal stromal tumor followed by multiple metastases. Cutaneous metastases from a gastrointestinal stromal tumor have been considered to be a late progressive manifestation suggested being an indicative of multiple metastases. This report emphasizes the importance of a full-skin examination in patients with a medical history of gastrointestinal stromal tumor which leads to find multiple metastases possibly treated with sunitinib.

[P310] Pancreatic extraskeletal osteosarcoma metastasizing to the scalp

( Hak Tae Kim ),( Young Jae Kim ),( Chong Hyun Won ),( Sung Eun Chang ),( Mi Woo Lee ),( Jee Ho Choi ),( Woo Jin Lee ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.1

Extraskeletal osteosarcoma (ESOS) is a rare mesenchymal soft tissue neoplasm which accounts for approximately 1% of all soft tissue sarcomas. More than 70% of this malignant tumor progresses local recurrence and metastasis. It is commonly metastasized to the lungs, lymph nodes, bone, and skin with poor survival outcome. Cutaneous metastasis is an exceedingly rare and known to be a flag sign of widespread metastases. We present a 57-year-old woman presented with a rapidly growing protruding mass on the scalp which is finally diagnosed with metastatic ESOS from primary pancreatic ESOS. To our knowledge, there has been no reported case of pancreatic extraskeletal osteosarcoma metastasizing to the scalp.
