이상정 장군의 육필 유고 『표박기(飄泊記)』 분석

이상규(Lee, Sang-gyu) 동아인문학회 2017 동아인문학 Vol.39 No.-

글은 이상정의 생애와 업적을 살펴보고, 그가 남긴 유고집의 의미와 사료적 가치를 조망하는 것을 목적으로 한다. 자료의 한계로 인해 그 전모 전체를 밝히기에는 어려움이 있지만 본 논의의 의미는 다음과 같이 정리할 수 있다. 이상정의 조국 독립군으로서의 활동을 살펴볼 수 있었고, 우리나라 최초의 여유 비행사였던 권기옥의 독립투쟁사를 밝힐 수 있었다. 뿐만 아니라 동북아시아 특히 한・중의 과거 관계를 알 수 있는 역사 사료로서의 가치를 발견할 수 있었다. 우리나라 고대사의 흐름을 제대로 이해하기 위해서는 동북 지역사에 대한 새로운 인식이 필요하다. 책의 내용을 보면 중국 동북삼성뿐만 아니라 곳곳의 유적지를 답사하며 고적과 유물의 역사와 유래에 대한 글을 남기고 있기 때문이다. 또한 『개벽(開闢)』 잡지 등에 그가 남긴 여러 편의 시조를 살펴보면 문예가로서의 면모도 발견할 수 있는데, 유고집에 남긴 이러한 글들은 문예집으로서도 가치를 지닌다고 할 수 있다. The purpose of this paper is to examine the life and achievements of General Lee Sang-jeong and identify the meaning and historical value of posthumous collection he left. Although there are difficulties in clarifying the full account due to the limitations of data, the significance of this paper can be summarized as follows. It could examine the activities of General Lee Sang-jeong as an army for national independence, and clarify the struggles for independence by Kwon Ki-ok, the first female pilot in Korea. Moreover, this paper could discover values as a historical record to know the past relationship in Northeast Asia, especially Korea and China. It is necessary to have a new recognition of the regional history of Northeast Asia to properly understand the flow of the ancient Korean history. By exploring historical sites in the 3 provinces of Northeast China as well as various places, the book leaves many writings about the history and origins of historical remains and sites, whose quality surpasses that of the writings by renowned, excellent historical scholars. Also, several sijo (Korean traditional three-verse Korean poems) in magazines such as ‘Gaebyeok’ show General Lee Sang-jeong’s talent as a literary artist, indicating the significant value of the pieces he left in his posthumous collection as a literary collection.

Castleman' s disease is a rare, reactive lymphoid proliferation of unknown cause and pathogenesis. Depending on histololgic findings, it has been divided into two distinct histologic subtypes that include hyaline-vascular type(90%) and plasmacell type(10%). This disease occurs most commonly in mediastinal lymph nodes and cervical lymph nodes, inguinal lymph nodes respectively. But occurs rarely in retroperitoneum. We report a case of hyaline-vascular type asymptomatic Castleman' s disease of the retroperitoneum in a 47-year-old man.

BCR-ABL 융합 유전자를 동반한 급성골수구성백혈병은 그 빈도가 매우 낮고, 만성골수구성백혈병의 급성악화기와 임상적으로 유사한 특징을 가진다. 항암화학요법으로 관해유도가 되기 어렵거나, 관해유도 후 재발의 빈도가 높은 특징을 가지고 있어 예후가 나쁘다고 알려져있다. 저자들은 BCR-ABL 융합 유전자를 동반한 급성골 수구성백혈병1례를 경험하였기에 문헌고찰과 함께 보고 하는 바이다. BCR-ABL fusion gene is the hallmark of chronic myelogenous leukemia (CML), but it has been rarely reported in acute myeloid leukemia (AML). AML with BCR-ABL fusion gene has different features from blast crisis of CML. We experienced a rare case of AML with BCR-ABL fusion gene. Here we report this case with a brief review of literatures.

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

Nb(OC₂H?)?를 원료로 하여 AP-MOCVD에 의한 N₂O?박막의 성장과정을 기판온도, carrier gas유량, 원료온도, 반응 O₂gas의 함수로 in-situ Ellipsometry에 의해서 조사하였다. 실험결과 얻어진 Δ-Ψ곡선은 투명균질막의 이론적 Δ-Ψ곡선에 잘 일치하였으며 성장과정은 473∼673K의 저온영역에서는 1단계적 직선 성장거동을 나타내었고 673∼753K의 고온영역에서는 2단계의 직선적 성장거동을 나타내었다. 석출된 박막의 밀도를 의미하는 굴절율은 기판온도 673K까지는 증가하나 그 이상의 온도에서는 감소하기 시작했다. 그리고 산소를 첨가하지 않았을 경우는 723K에서 석출된 박막이 가장 뛰어난 내식성을 나타내었는데 이것은 이 온도에서부터 석출박막이 δ-Nb₂O?로 결정화하기 때문이라 사려된다. By the Nb(OC₂H?)? source, Growth process of Nb₂O? films formed by AP-MOCVD has been examined by in-situ Ellipsometry as a function of the substrate temperature, carrier gas flow rate, source temperature and reactant O₂gas flow rate, Δ-Ψcurve obtained in experimental results corresponded to the theorical Δ-Ψcurve of transparant homogenious film, and showed a rectilineal growth behaviour of the one stage at a low temperature range of 473∼673K and indicated a rectilineal growth behaviour of the two stage at the high temperature of 673∼753K. A refractive index meaning density of the deposited film increased until 673K of the substrate temperature but decreased above 673K. In the absence of oxygen, The thin film deposited at 723K showed the most excellent corrosion resistance, because the deposited film was crystallized into the δ-Nb₂O? above 723K.

Most of our college students in the department of electricity are from technical high school. Thinking that a lot of those high school students are going to try out for our college, we have come up to the idea to have stable student resources and to keep the resources that we should have researched on this matter. As first solution, considering scholastic ability for students, our college should help them to have easier understandings on their major subject studies. To let them have better condition of studying, we have analyzed 6th and 7th high school curriculum for electric text and studied how much influence 7th the curriculums have on major subject studies. Also we have looked through high school mathematics and basic electric texts under 7th the curriculums. After examining these analysis, we have had some suggestions about the ways to provide easier understandings and reorganized contents in a major basic text of college.

Various surface properties of boride layer formed by plasma paste boronizing were examined. A boride layer of flat structure was formed on the STS 304 stainless steel substrate by plasma paste boronizing treatment with several different temperature from 1023K to 1223K under gas mixture of Ar/H₂: 2/1(vol.%). The paste was composed of 30wt% boron and 70wt% borax. The properties of boride layer were evaluated by micro vickers hardness tester, SEM, EPMA, and corrosion tester. Metallographic cross section of the borided specimen was consisted of the boride layer, Ni rich layer, Cr rich layer, and matrix structure. It was found to form boride layer in a short time to conventional boronizing methode. In XRD analysis of boride surface, various peaks such as FeB, Ni₃B and CrB were presented. Especially, the peak of CrB was more intensive than other peaks. Activation energy for the formation of boride layer was found to be 123kJ/mol which is lower than the conventional boronizing treatment. The microhardness of these boride layers were in the range of HV 1800∼2000. However, from the results of anodic polarization curve in 1M H₂SO₄solution on the borided specimens, it is found that the corrosion resistance is improved by boronizing treatment. Primary current density is, however, increased with the Boronizing temperature.
