‘세계대공황’과 마르크스주의 위기론

김성구(Seong-Gu Kim) 경상대학교 사회과학연구원(마르크스주의 연구) 2011 마르크스주의 연구 Vol.8 No.3

저자는 『세계대공황』에서 이번 금융위기를 ‘세계대공황’으로 규정하고, 신자유주의 금융위기의 전개와 구조 그리고 그 결과에 대한 뛰어난 마르크스주의적 분석을 제공한다. 그러나 다른 한편 저자는 자본주의의 주기적 공황과 구조위기를 차별하지 못하고 자본주의 공황의 원리론과 현대자본주의론을 매개하지 못함으로써 2007-2009년 위기의 중층적 성격을 파악하는 데 한계를 드러낸다. 이른바 세계대공황이 주기적 공황인지 아니면 구조위기인지, 또 세계대공황의 원인이 무엇인지 이론적으로 일관되게 설명하지 못하는 것은 이런 한계 때문이다. Soo-Haeng Kim’s new book World’s Great Crash (2011) offers an outstanding Marxist explanation of the 2007/2009 financial crisis, especially of the devastating effect of financial innovation and derivatives in housing finance. However, it also shows some theoretical weakness in understanding the twofold character of this crisis as both cyclical and structural crisis, and basing the analysis of today’s crises on Marx’s crisis theory as well as the theory of contemporary capitalism. It is due to this weakness that the author cannot be theoretically consistent in explaining the so-called world’s great crashes and the causes of them.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

An agricultural land application of swine slurry is one of the best management practices in Jeju island whose ground water must be protected. So as to study the effect of appling swine slurry on ground water or aquifer, incubation-leaching technique was used by assuming the incubating period of 1, 2, 4, 8, 16, or 32 days, and application rate of 3200.0㎎T-P/ℓ, 820.0㎎T-P/ℓ, and 1887.0㎎K^+/ℓ in swine slurry. The leachates were collected from the soil columns(PVC 30㎝L×5.5㎝D) packed 15㎝ in depth with Gangjeong soil series by washing with 100mL distilled water. The leached components were measured by using Ion chromatography for Cl^-, NO_3-N, F^-,Br^-, Na^+, K^+, Ca^2+, and Mg^2+, atomic absorption spectrophotometry for Fe and Mn, and UV-Vis spectrophotometry for T-N and T-P. Application of swine slurry in naked soil could influence on the ground water or aquifer by increasing nitrate-nitrogen in leachate with time, or leaching the cations present in soils in accompany with anions because of H^+ produced in nitrification. Therefore, careful consideration should be taken about what amount, when, where, and how for protecting ground water system.

As the micro technology and miniaturization of a structure and component in the last couple of decades have been concretely realized, the understanding of structural and dynamic characteristics and prediction of dynamic behavior are indispensable to the miniaturized structures and micro machines. This paper shows the effect of dynamic characteristics in bolt-jointed structures by comparing natural frequencies and mode shapes between macro and micro-scale beams through experimental modal analysis and finite element analysis with a1 8 test models by materials, by size, and by joining condition; that is, SS41 and A16061-T651, micro and macro, and monolithic beam and bolt-jointed beam.

In the present study, mixing characteristics of solid particles in bubbling fluidized bed have been analyzed in a freely bubbling two-dimensional bed experimentally. Verticall and horizental particles mixing was studied by using heated particles as tracers. The steady-state temperature patterns around a heated wire and transient response to an injected pulse of heated particles were measured. A qualitative study of bubble size, velocity and void fraction in the two -dimensional bed was made by using a high-speed viedo recorder. Through the screen anlaysis of bubble flow it was verified that the size of bubbles increases with the rise of excesive velocity or bed height. Steady state experitments gave the result that the movement of heated particles in beds was more vigorous in higher excessive velocity. In trasient experimet the higher excesive velocity delay time of high temperature particles injected into the bed were the shorter. Dispersion coefficient was found to be increased with grouth of the bubble size and excessive velocity.

A 48-year-old male visited the emergency room of the authors’ hospital due to nausea, vomiting, and myalgia for four days. Acute hepatitis A was identified from the serologic marker of the hepatitis A virus. Mild elevation of the serum creatinine and creatinine phosphokinase(CPK) suggested rhabomyolysis, which was confirmed with the serum aldolase, myoglobin, and urine myoglobin. With supportive care, both the liver and renal func- tions were recovered gradually and fully. This case shows that rhabdomyolysis can be one of the mechanisms of renal complication in cases of acute symptomatic hepatitis A.

A System is described for measuring the parameters characterizing the local state of fluidization in beds of aritrary sizes. This system is based on a minaturized pressure probe shaped so as not to disturb the local state of fluidization. Based on a statistical analysis of the signal, the mean bubble plulse duration, the number of bubbles striking the probe per unit time and the local mean bubble rise velocity are measured. The latte is measured by using the cross-correlation technique from these parameters, further characteristics of the local state of fluidization are derived, in particular the local mean pierced length of bubbles and the bubble gas flow.

全北 平野地인 裡里地方에서 옥수수의 播種期와 地上部生育 및 種實收量과의 관계를 調査하여 다음과 같은 결과를 얻었다. 1. 播種期의 早晩이 莖葉의 生育 및 種實收量에 크게 영향을 끼치며 播種이 늦어질수록 出雄, 出絲, 生育日數가 짧아지고 地上部生育은 떨어지는 경향이다. 2. 莖葉生育은 4月 20日 播種을 基點으로, 種實收量은 5月 5日 播種을 基點으로 各各 減少되었다. 3. 地上部諸形質과 種實收量간에는 高度의 正의 相關이 인정되며 種實增收를 위하여는 莖葉生育은 크게 할 필요가 있다. Some results were gained through the experiment that was carried out with a single cross cultivar, Suweon 19, of maize (Zea mays L.) in Iri, the Jeonbug plain area, in 1980, to check relationships between growth characters at different sowing dates. 1. The foliage growth and grain yield were greatly influenced with planting season. The number of days to tasseling, silking, or maturing shortened and the growth of maize decreased as sowing was delayed. 2. The threshold sowing date for foliage production seemed to be April 20 and that for grain yield, May 5. 3. Highly significant positive correlation existed between vegetative growth and grain yield. This may mean that increasing vegetative growth is prerequisite to better grain yield.

제주지역에서 생산되는 식물 중에서 파리풀(지방명;가신새), 삼지구엽초, 미역, 톳, 표고버섯 및 만년버섯(일명;영지)에서 열수 및 냉수추출물을 얻어 마우스 암모델 세포인 sarcoma-180 세포를 ICR 마우스에 이식하여 고형암 성장저지율과 수명연장율에 대한 항암성을 검색한 결과는 다음과 같다. 산초추출물의 항암효과는 파리풀에서 53.4%, 삼지구엽초에서 58.2%의 고형암 성장저지율을 보였다. 해조류추출물의 항암효과는 톳에서 63.1%, 미역에서 38.2%의 고형암 성장저지율을 보였다. 버섯추출물의 항암효과는 만년버섯에서 62.8%, 표고버섯에서 66.4%의 고형암 성장저지율을 보였다. 산초, 해조, 버섯류 각 추출물에서 복수형암에 대한 효과는 매우 낮았다. 모든 시료는 일정량을 초과 투여한 실험군에서 고형암 성장저지효과가 낮거나 수명이 단축되었다. The hot and cole water extracts were obtained from herbs (Phryma leptostachya and Epimedium koeranum), seaweeds(Hizikia fusiforme and Undaria peterseniana), and mushrooms(Gonoderma luciolum and Lentimus deodes) among which have long been known to have antitumor effects. These extracts were tested on growth inhibition rate(I.R) of solid tumor and prolongation rate(P.R) in animal experiment using ICR mouse with a mouse tumor models sarcoma-180 cell. The results were as follows ; The antitumor effects of herb extracts were 53.4% with Phryma leptostachya and 58.2% with Epimedium koeranum in growth inhibition rate of solid tumor. The antitumor effects of seaweed extracts were 63.1% with Hizikia fusiforme and 38.2% with Undaria peterseniana in growth inhibition rate of solid tumor. The antitumor effects of mushroom extracts were 62.8% with Ganoderma luciolum and 66.4% with Lentinus edodes in growth inhibition rate of solid tumor. The effects on ascite tumor of extracts from herbs, seaseeds and mushrooms were so low that no anititumor effect could be recognized. All the samples showed low growth inhibition rate of solid tumor or short life in over dose groups.

Objective: The aim of this study was to investigate the clinical significance of myocardial injuries in patients with nontraumatic intracranial hemorrhage by identifying the occurrence of myocardial injury and defining its correlation with subsequent cardiovascular events. Subjects and methods: One hundred twenty-four patients with nontraumatic intracraninal hemorrhage presented to the emergency department within six hours from onset of symptoms were enrolled. Brain CT, serial electrocardiography, and echocardiography were done at the emergency center. Blood samples for troponin I and creatine kinase(CK)-MB were drawn immediately and eight hours after admission, Troponin I and CK-MB were measured using a chemiluminescent immunoassay, respectively. Results: Electrocardiographic and echocardiography abnormalities were found in 65 cases(52.4%) and 21 cases(17%), respectively. Serum troponin I and creative kinase-MB were increased in 35 cases (28.2%) and in 58 cases(46.8%), respectively. Abnormal findings of echocardiography and ECG, as well as elevated levels of serum troponin I and creative kinase-MB, were associated with an increased risk of cardiovascular event and survival. Logistic regression analysis revealed that an abnormal echcocardiographic finding and elevation of serum troponin I were factors associated with the occurrence an adverse cardiovascular event and that electrocardiographic abnormalities and initial mental status were factors associated with poor prognosis. Conclusion: This study reveals that actual myocardial injury develops in a significant proportion of patients with nontraumatic intracranial hemorrhage and that the development of the myocardial injury is associated with an adverse cardiovascular event that occurs during admission.
