In order to establish a dyeing method with Magnoliaceae tree species dyeing was examined with 4 different parts, leaf, stem bark, root, flower of 4 Magnohaceae species, Magnolia kobus Dc., Magnolia denudata Desr, Magnolia obovata Thunb, Liriodendron tulipifera L Mordants used were chemicals, AIK(SO_4)_2 24H_2O, Ca(OH)_2, FeSO_4 7H_2O. All four species showed similar coloring among four different parts. Leaves and petals showed dark yellow, stem bark, grayish yellow, root bark, dark red or yellow. Al mordant made more brighter colour than Fe mordant. Stem bark showed less difference in color by mordants, whereas petals did the biggest.

Diphenylhydantoin이 백서뇌신경세포막의 Na^+, K^+ -ATPase에 미치는 영향

황인방,허강민,이재흔,석정호 충남대학교 의과대학 지역사회의학연구소 1990 충남의대잡지 Vol.17 No.1

To study the effect of diphenylhydantoin on the synaptosomal Na^+ K^+ -ATPase in the rat with Goldblatt kidney, one kidney was removed and renal artery on the other side was partially ligated (external diameter=0.38mm). One kidney was removed in the control group. Synaptosome was prepared from the control and hypertensive rat and ATPase activity (total, EGTA, Azide and ouabain sensitive) was measured in the presence or absence of saponin. The effect of diphenylhydantoin on the synaptosomal ATPase was observed in the presence of diphenylhydantoin and/or ouabain. To investigate the maximal binding of ouabain to synaptosome, ouabain binding study was also carried out. Results as follows: 1. Blood pressure was significantly increased in 1-kidney, 1-clip hypertensive rat. 2. ATPase activity(Total, EGTA and ouabain sensitive) was increased to 2 times in the presence of saponin in the hypertensive and control group. 3. Na^+, K^+ -ATPase activity in hypertensive group was significantly decreased, compared with the control group. 4. Diphenylhydantoin slightly increased the ATPase activity in the control and hypertensive group, but it was not significant. 5. Total activity of ATPase was significantly decreased in the case with dephenylhydantoin and ouabain, but there was not difference between ouabain and ouabain with diphenylhydantoin treated case. 6. In the experiment of oubain binding, diphenylhydantoin did not alter Bmax and Kd of hypertensive and control group. From the above results, it is suggested that diphenylhydantoin will decrease the intracellular sodium without dependence on the stimulation of Na^+, K^+ -ATPase-in hypertensive rat.

Endoscopic submucosal dissection of early gastric cancer with mixed-type histology : Protocol for a systematic review and meta-analysis

Bang, Chang Seok,Choi, Jae Ho,Yang, Young Joo,Lee, Jae Jun,Baik, Gwang Ho Wolters Kluwer Health 2018 Medicine Vol.97 No.51

<P><B>Abstract</B></P><P><B>Background:</B></P><P>Endoscopic submucosal dissection (ESD) is a primary treatment for the early gastric cancer (EGC) who have a negligible risk of lymph node metastasis satisfying specific criteria. These criteria are histologically categorized by EGC with differentiated-type histology (EGC-DH) and undifferentiated-type histology (EGC-UH). However, gastric cancer is histologically heterogenous and there has been no specific criteria for EGC with mixed-type histology (EGC-MH). Moreover, therapeutic outcomes of ESD for EGC-MH have not been clearly described.</P><P><B>Methods:</B></P><P>We will search the core databases (MEDLINE (through PubMed), the Cochrane Library, and Embase) from their inception to November 2018 using pre-established searching strategy by 2 independent evaluators. The P.I.C.O. is as follows; Patients: who have EGC-MH, Intervention: ESD, Comparison: none, Outcome: at least one among the rate of complete resection, curative resection, en bloc resection, recurrence or procedure-related adverse event that enabled an evaluation of feasibility of ESD. All types of study design will be sought and publications in English with full-text will be included. The risk of bias will be assessed using the ROBINS-I tool. Descriptive data synthesis is planned and quantitative synthesis will be used if the included studies are sufficiently homogenous (pooled therapeutic outcomes data with 95% confidence intervals). Publication bias will be assessed with quantitative analyses if more than 10 articles are enrolled.</P><P><B>Results:</B></P><P>The results will provide evidence for validity of current ESD criteria in addition to the technical feasibility of ESD for EGC-MH.</P><P><B>Conclusion:</B></P><P>This study will provide evidence of ESD for EGC-MH.</P>

현덕 유년동화의 놀이 모티프에 나타난 현실 인식 -노마 연작을 중심으로-

방재석 ( Jae Seok Bang ),김하영 ( Ha Young Kim ) 건국대학교 동화와번역연구소 2015 동화와 번역 Vol.30 No.-

본 연구는 현덕이 놀이모티프를 활용한 유년동화에서 자신이 인식하고 있는 현실의 문제를 제기하는 방식을 살펴보고자 하였다. 이를 위해 현덕의 유년동화39편 가운데 놀이 과정이 형상화 된 16편에 나타난 놀이 모티프를 유형별로 분류하고 그 의미를 분석하였다. 로제 카이와의 놀이 구분에 따르면 현덕 유년동화의 놀이모티프는 아곤, 미미크리, 아곤과 미미크리의 혼재가 나타나는 놀이로 분류할 수 있다. 현덕은 아곤형놀이를 통해 현실의 계급 문제를 제기하고, 미미크리형 놀이를 통해 문제의 해결책을 강구한다. 아곤과 미미크리가 혼재된 현덕의 작품에서 계급적 질서가 투영된 세계는 아이들이 제시하는 다른 놀이를 통해 새로운 질서를 가진 세계로 재구성된다. 현덕이 제기하는 현실의 계급적 문제는 현덕의 소설이나 소년소설에서도 나타난다. 그러나 유년동화에서 제기되는 계급 문제는 타 장르에 비해 간접적으로 드러나고, 놀이 모티프를 장치로 사용함으로서 부유한 환경의 아동마저도 포용하는 대안적 세계를 제시한다는 점에 주목할 필요가 있다. 현덕 유년동화에서 놀이 모티프의 활용은 아동 모두를 포용하는 세계를 재구성하는데 기여하고 있다는 점에서 매우 중요하다. This research aims to study about how they question problems in reality that they recognise reflecting to the play motif of Hyunduk children’s story. It is toassort the play motifs on episode 16, which the play process is exemplified, of the whole 39 series by type in order to analyse the meaning. According to Roger Caillois’s play sort, the play motif of Hyunduk children’s story can be sorted as agon, mimicry, and combination of agon and mimicry. Hyunduk suggests hierarchy problems by agon game, and looks for a solution by a mimicry type game. In Hyunduk’s work of the combination of agon and mimicry,the world reflecting to hierarchical order is re-created as a new world with a new order through another game suggested by the children. The hierarchical problems in reality that Hyunduk suggests appear in Hyunduk’s works and adolescence novels. However, hierarchical problems suggested in children’s stories appear indirectly comparing to that in other genres, and as using a game motif as the tool, it is worth looking at the point that it suggests an alternative world embracing children with wealthy backgrounds. It is very important to notice that the use of a game motif in Hyunduk children’s story contributes to the reconstitution of a new world embracing all children.

베트남전쟁과 한

방재석(Jae Seok Bang),조선영(Sun Young Cho) 한국현대소설학회 2014 현대소설연구 Vol.- No.57

Although exchange between Korean and Vietnam has been increased dramatically from all areas in society after resuming diplomatic relations in 1992, there are still lack of understanding of each other. To overcome prejudice and hostility between two countries and contribute to development of ethical culture, understanding Vietnam War which led to discontinuities must be a priority. The United States intervened Vietnam War under the domino theory and anti-Communist logic. Korea also participated in the War as an ally of the United States, Park Chung-hee government expanded and reproduced domino theory and anti-Communist logic from the United States in order to stabilize regime and build infrastructure of economic development. Of many literatures regarding Vietnam War, 『White Badge』 by Ahn, Jung-Hyo is a work that specifically embodied domestic and foreign circumstances and operational tactics. In 『White Badge』, metal trauma and destroyed life of the characters were resulted from the war, which allows Korean literature to encounter with Vietnam literature. A Vietnamese writer, Bao Ninh describes the cruelty of war and human devastation in 『Sorrow of War』. Vietnam literature and Korean literature encounters in the course of realizing the fact that people unrelated to the war would eventually become victims by ruling ideology and external force. Since Korea has established diplomatic relations with Vietnam, ``a meeting of young writers for understanding Vietnam`` was started in 1995 and has constantly performed human exchange in the field of literature. There is a paucity of literary works in spite of many efforts in the field of creation and translation. To let the world know about the fact that literature of the two countries endeavors to protect the universal values of human rather than ruling ideology and interests in favor of their countries, more efforts will be required to introduce many works and translate them. Without being limited to bilateral relations, literary exchange between Korea and Vietnam has significant meanings because that the center can not save the periphery; that only human and life stand for values; and that two countries meet together serving as supporters on the ground of historical assets.

Literature and religion have the same aspect of dealing with the fundamental matter concerning human and the world. Literature treats the world with the daily life of human, while religion has the understanding of the world focused on the Providence of God. Lee Cheong-jun studies deep into the matters concerning the existence of God and the salvation of human. To him, a novel is regarded as religion because of art as the process to seek the truth. Although he accepts Christianity, he criticizes its blind obedience and the way of one - sided salvation. He understands Almighty God reigning over people as an incomplete being needing human help, and gives human the responsibilities to lead their lives independently. His ideal religion is not oppressive with a dominant-subordinate relationship between God and human, but ``horizontally open``. The religion in his novels is ``the present progressive form`` to be accomplished by both God and human. Its truth is an object of creation, not faith. God and human make the truth together and share the process. Always the truth is incomplete, and that means it has the possibility of sustainable progress, not deficiency. The core of views of both art and religion of Lee Cheong-jun is to pursue genuine freedom and faith by doubt and question, not blind obedience to the absolute. He disagrees on the literature hindering religion as well as the religion restricting human. His literature is well worth studying in the ways that it is understood the religion pursuing the salvation of human by infinite freedom of literature following uselessness, and the truth is changing into the object of creation.

LTE에서 이기종 네트워크(Heterogeneous network)와 DUDe(Downlink/Uplink Decoupling)기술은 채널 간 간섭을 완화시키고, 셀 용량을 증가시켜주는 중요한 기술이다. 매크로 셀(Macro Cell) 안에 복수 개의 소형 셀(Small Cell)을 설치해 UE가 여러 유형의 엑세스 노드를 사용할 수 있게 하였고, UE(user equipment)가 상 · 하향링크를 각각 최적화된 채널을 생성할 수 있는 기지국에 독립적으로 연결할 수 있게 해주었지만, 여기에 다중 안테나 기술(MU-MIMO, Beamforming)을 적용하면 안테나 개수를 늘리면 Coverage를 더 넓힐 수 있고, 셀 용량을 더 늘릴 수 있는 것처럼 더 좋은 효과를 볼 수 있다. 본 논문에서는 상 · 하향링크 분리를 이기종 네트워크 환경에서 시뮬레이션 하고, 매크로 셀, 소형 셀, UE의 안테나 개수를 늘려가며 채널 용량과 DUDe Zone 범위를 분석한다. 안테나 수가 많아지면 독립적인 채널의 수가 증가하고, 복수의 UE에 각각 다른 데이터를 동시에 전송 및 수신할 수 있게 된다. 안테나 수를 비교하여 확인한 결과, 안테나 수가 많을 때 Cell에서 수용 가능한 사용자 수가 많았으며, 더욱 넓은 Coverage를 갖게 된다는 것을 확인했다. 즉, 안테나 수를 증가시키면, 더욱 많은 UE가 DUDe를 잘 활용할 수 있는 환경이 될 수 있다.
