금융산업 구조조정과 금융기관 위기대응력 연구

김동옥 한국상업교육학회 2014 商業敎育硏究 Vol.28 No.2

금융기관이 위기경험에도 불구하고 기존의 위험문화 또는 사업모델을 유지하는지(위험문화가설),아니면 학습효과로 인하여 후행위기에 대비하는지(학습효과가설) 여부에 따라 효과적인 금융규제의형태가 달라질 것이다. 위험문화가설이 타당하다면 위기에 취약한 특성을 보유한 금융기관에 집중한 규제가 효과적일 것이나, 학습효과가설이 타당하다면 기본적이고 원칙적인 규제의 실효성 확보에 집중하는 것이 바람직할 것이다. 김동옥·양철원(2013)은 우리나라 금융기관을 대상으로 학습효과가설을 지지하는 결과를 확인하였으나, 동 결과는 생존편의가 효과적으로 통제되지 않은 상태에서도출된 것이다. 본 연구는 생존편의를 통제한 후에도 학습효과를 확인할 수 있는지 여부를 살펴보고, 선행위기수익률 수준별 분석을 통하여 학습효과가설을 엄밀하게 검증한다. 첫째, 1997년 금융위기 이후 추진된 금융산업 구조조정 과정의 인수합병 사례를 조사하여 생존편의효과 발생 가능성이있는 금융기관을 제외하고 회귀분석을 실시한 결과 선행위기수익률과 후행위기수익률 간 통계적으로 유의한 음의 상관관계를 발견함으로써 학습효과가설을 지지하는 결과를 확인하였다. 이러한 음의 상관관계는 생존편의를 보수적으로 통제하는 경우 더욱 유의적으로 강화되었다. 둘째, 선행위기수익률과 후행위기 수익률 간의 이러한 음의 상관관계가 상대적으로 선행위기수익률이 저조한 금융기관의 경우에 더욱 강하게 나타나는 것을 확인함으로써 학습효과가설을 지지하는 추가적인 증거를 찾았다. This paper analyzes which is the more appropriate for Korean financialinstitutions between the learning hypothesis and the risk culture hypothesis. Kimand Yang(2013) supported the learning hypothesis and concluded that Koreanfinancial institutions raised the confrontational ability to crisis after crisisexperience. But this study has the limitation which is the ignorance of effectivecontrolling for survivorship bias. Thus there is possibility of contamination ordistortion from it. Analyses in this paper are directly related to those presented inKim and Yang(2013) and indirectly to those in Fahlenbrach et al.(2012). First, this paper shows the results after controlling for the survivorship bias. Isort the financial institutions who has the possibility to cause survivorship bias bylooking into the merger and acquisition events of each financial institution. Theregression results without these financial institutions is supportive of the learninghypothesis. The regression coefficient on the preceding crisis (1997 crisis) returnsto the posterior crisis (2008 crisis) returns is statistically significantly negative. The absolute value of regression coefficients are increased as the strength ofcontrol for the survivorship bias is increased. Also, the coefficient on determinationis increased with the stronger control for the survivorship bias. Second, I find additional evidence to the learning hypothesis. The negativeassociation between the two crisis returns is more strongly found for financialinstitutions who relatively performed bad during the preceding crisis. More detailed search for learning contents and the differences by type ofinstitutions is left as the future assignments.

灰鑄鐵을 中周波 誘導爐에서 熔解할때의 殘留酸素 含量의 決定과 熔湯中에 酸化鐵로서 强制로 酸素量을 增加 시켰을때 熔解酸素量이 接種效果에 미치는 影響을 檢討한 바 다음과 같은 것을 究明하였다. (1) 中周波 誘導爐에서 灰鑄鐵 熔解時 殘留含有酸素量은 80∼100ppm 範圍이다. (2) 炭素當量이 작을수록 黑鉛核數는 減少하여 酸素量 增加에 따르는 黑鉛核 生成數는 減少하고 硬度는 커진다. (3) 黑鉛核 生成에 要하는 活性化 Energy는 Mill Scale을 3% 및 6% 添加하였을 때 各各 15,000 ㎈/㏖ 및 21,000 ㎈/㏖ 이었다. (4) 酸素合有量 變化에 따르는 黑鉛形狀은 酸素含有量 增加에 따라 粗片狀, 薔薇形 共晶形으로 變化하였다. The amount of retained oxygen and it's relation with the formation of graphite in the gray cast iron melted with the medium frequency induction furnace were investigated. And also the effect of retained oxygen on the inoculation by adding mill scale as the oxidizing agent at 1,450℃, 1,500℃, and 1,550℃ respectively were studied. The results were as follows: (1) The amount of retained oxygen was approximately 80-100 ppm (2) The number of graphite nucleus was decreased as carbon equivalent decreases. The number of nucleated graphite was decreased and the hardness was increased, as increasing the amount retained oxygen. (3) when 3% aad 6% mill scale, respectively, were added into the molten gray cast iron, the activation energy for the graphite nucleation was 15,000 ㎈/㏖ and 21,000 ㎈/㏖, respectively. (4) The shape of graphite, as the amount of retained oxygen increases, was changed from coarse flake, rossete to eutectic gradually.

To control the position, velocity and torque of the ultrasonic motor, a great variety of method are proposed such as the amplitude, phase difference, frequency and so on. In the case of phase difference method, it has some advantages; it can control the direction and velocity of rotation only adjusting the phase difference and it has wide control-band. During the USM driving on adjusting phase difference, its characteristic was transformed by the change of resonance-frequency of stator, which means that the resonance frequency is different according to the phase difference. Consequently, we need to set up the most suitable driving frequency according to each phase difference.

This paper aims to find out an alternative method by analyzing embedded tensed clauses differently from the analysis with category-changing phrase structure rules. Particularly our concerns are extraposition and topicalization of that-clauses without any head noun. Our basic assumptions are as follows: (i) All the phrases are endocentric ; (ii) Extraposition is optional; (iii) Topicalization is applied only to NP￣ instead of S￣. Assumption (i) implies that there is no category-changing phrase structure rules. Therefore, we must analyze that-clauses as [NP￣NP S￣]. In this structure, the NP is null, but the NP is realized as it after extraposition is applied optionally. Otherwise the NP is deleted. Our analysis elicits some theoretical problems. These problems are solved within our framework. We examine some analyses including Stowell(1984) thoroughly. As a result, we make clear that our analysis is more plausible theoretically as well as practically.

This paper examines the financial difference between the large firms and the small-medium sized firms in Korea and the U.S. The useful 13 financial ratios are selected to represent liquidity, activity, leverage and profitability. The data are collected from manufacturing industries by SIC code. First', the paper analyzes the mean difference of financial ratios by t-test. The result indicates that there is significant differences between the two groups in ratios representing liquidity, activity, and leverage in both countries. Second, factor analysis were used to reduce ratios to several principal components which have no correlation. The results show 4 major factors in the U.S and 3 factors in Korea. Finally ANOVA is carried out seperately for those major factors and individual ratios which have the highest factor loading in each factor. The results find the significant difference in liquidity, activity, and leverage as whole. Particularly small and medium sized firms show high sales/fixed assets ratio and low current ratio in the U.S. and high sales/total assets ratio in Korea. Therefore this study identifies the financial characteristics of small and medium sized firms indicating that they are more efficient in asset operation in Korea and the U.S. The results suggest that asset turnover ratios are the most important ratios to characterize the difference between small and large firms. This implies that the management of small business should focus on maximizing activities.
