The Effects of Microeconomic Fundamentals on the Korean Financial Crisis

Kim,Sunghwan,Kim,Hong Kee,Kim,Jin San 한국산업경영학회 2010 한국산업경영학회 발표논문집 Vol.2010 No.1

In this study, we assess the effects of default risks and financial performance of firms on the overall risk of Korea around its financial crisis in the late 1990s and on their market values, using firm-level data from 1991 to 2007. We develop default prediction models and calculate Altman’s K scores to measure the overall risks and quality of firms respectively. Based on our own default prediction models, we have shown that the default risks of firms were extremely high before the crisis and drastically declined after the crisis. We have also found that the default risks of chaebol firms were much lower before and after the financial crisis and that their market values were much higher after the crisis, compared with those of non-chaebol firms. This implies that the Korean economy with high sovereign risks for a long time experienced the crisis due to weak firm-level fundamentals, regained its vitality due to significant improvements made by chaebol firms through the crisis and has become much stronger than before.

김용훈,권현철,김필호,안석진,유철웅,최진호,이상철,김준수,김덕경,전은석,이상훈,홍경표,박정의,서정돈 대한내과학회 2004 대한내과학회지 Vol.66 No.5

목적 : 경피적 관동맥 중재술은 최근 양적 및 질적으로 급격한 발전을 보였지만 시술 시 천자부위의 혈관 합병증은 아직 해결해야 할 문제점이다. 저자들은 대퇴동맥을 통한 경피적 관동맥 중재술을 환자에게 천자부위 지혈을 위한 혈관폐쇄기구인 안지오실의 안전성과 유용성을 고식적인 용수 압박법과 비교 연구하고자 하였다. 방법 : 2002년 4월부터 2003년 5월 사이에 삼성서울병원 심장혈관센터에서 대퇴동맥을 통한 경피적 관동맥 중재술을 성공적으로 시행한 200명의 환자(안지오실 사용군: A군, 100명, 고식적 용수압박법 사용군 B군, 100명)를 대상으로 시술 후 주요 합병증 및 경한 합병증, 지혈 후 환자가 자리에 앉기까지의 시간, 보행개시 가능시간, 총 재원 기간과 시술 1주 후의 합병증을 전향적으로 조사하여 비교 연구하였다. 결론 : 두 군에서 연령, 성별, 기저질환, 심혈관 질환의 위험요소, 시술의 종류, 시술 중 사용한 헤파린의 양, clopidogrel의 양, ticlopidine의 양, 지혈 시 수축기와 확장기혈압, ACT (activated clotting time)는 차이가 없었다. A군이 B군에 비해 시술 후 자리에 앉기까지의 시간 (A군: 4.3±0.3시간, B군: 13.7±0.8시간, p=0.004) 및 보행개시까지의 시간(A군: 6.8±0.5시간, B군: 18.8±2.1시간, p=0.013)이 유의하게 짧았다. 시술 후 주요 합병증은 두군 모두에서 관찰되지 않았으며, 경한 합병증의 전체발생은 A군에서 유의하게 적었다(A군: 28명, B군: 19명, p=0.003). 반상출혈의 경우는 A군에서 유의하게 낮았지만(A군: 3명, B군: 12명, p=0.01), 혈종, 출혈의 발생은 두군간에 차이가 없었다. 총 재원기간에는 두 군간에 차이가 없었다(p=0.239). 시술 1주 후 경과관찰에서 주요합병증은 역시 두 군 모두에서 관찰되지 않았으며, 경한 합병증의 전체발생은 두 군에서 차이가 없었다(A군: 15명, B군: 13명 p=0.418), 반상출혈의 빈도는 차이가 없었지만 혈종의 발생은 A군에서 더 낮았다(A군: 2명, B군:6명, p=0.004). 두 군 모두에서 출혈은 발생하지 않았다. 결론 : 대퇴동맥을 통한 경피적 관동맥 중재술을 시행한 환자에서 안지오실의 사용은 고식적 용수 압박법에 비해 환자의 침상 안정시간을 줄여 조기 활동개시가 가능하게 하였으며 국소합병증의 위험도를 일부 낮추어, 시술에 따른 환자의 불편을 현저하게 감소시킬 수 있다고 할 수 있을 것으로 기대된다. Background : Although the number and the quality of percutaneous coronary intervention have been recently increased dramatically, the vascular complication at puncture site is still the major cause of patients' morbidity. We evaluated the safety and efficacy of newly of newly-developed collagen-based arterial closure device, Angioseal after transfemoral percuatenous coronary intervention. Methods : This study was designed as a prospective single center non-randomized comparative study. A total 200 patients undergoing transfemoral percutaneous coronary intervention were enrolled between April 2002 and May 2003. They were divided into two groups; Angioseal group (group A, n=100) and manual compression group (group B, n=100). The baseline clinical and angiographic characteristics were reviewed. The time to sit up, the time to ambulation, the duration of hospital stay, major and minor vascular puncture site complications were monitored. The patients were followed-up for 1 week after procedure by telephone. Results : The baseline clinical characteriwtics, clinical diagnosis, cardiocascular risk factors, typesof procedure, doses and numbers of anticoagulants were similar between two groups. The blood pressure and activated clotting time were also similar. The time to sit up (group A: 4.3±0.3 hours, group B: 13.7±0.8 hours, p=0.004) and the time to ambulation (group A: 6.8±0.5 hours, group B: 18.8±2.1 hours, p=0.013) were shorter in group A. No major vascular complications were noted. The incidence of hematoma and bleeding were not significantly different between two groups. The incidence of ecchymosis, however, was significantly lower in group A (group A:12%, group B: 3%, p=0.001) The duration of gospital stay was similar between groups. During 7 days of follow-up period incidence of hematoma was significantly lower in group A (p=0.004). Although the incidence of ecchymosis was not significantly different between two groups. Conclusion : The angioseal may be associated with earlier ambulation and less patients' morbidity with low incidence of local complication rate compared to manual compression after transfemoral percutaneous coronary intervention.

김병후,정선욱,강연화,김윤,김창엽,홍진표,한오수,조맹제,김용익 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.5

Objectives : Attitudes of families of mentally ill, health personnels and community leaders to the mentally ill after the development and utilization of the community mental health program and reintegration of the chronically ill patients into society. This study was designed to compare the attitudes toward the mentally ill patient of the persons who have important role in treating the mentally ill and to find the variables influencing the attitudes. Methods : We measured attitudes toward mental illness in psychotic patients' families(N=139), community leaders(N=180) and health personnels(N=324) including mental health personnels before the implementation of community mental health services in Yonchon county and Seodaemun district area. The instrument used to measure attitudes was Opinion about Mental Illness(O. M. I.) scale. Results : 1) Health personnel showed lower Authoritarianism(Factor A) and higher Benevolence(Factor B) scores on the average than community leaders and psychotic patients families. 2) Current residence affect the attitudes in psychotic patients' families, not in community leaders and health personnels. Families in urban area showed lower Authoritarianism(Factor A) and Social Restrictiveness(Factor D) and higher Benevolence(Factor B) scores than in the rural areas. 3) Many patient variables were correlated to the attitudes of families. Duration of illness, number of recurrence, number of admission, age of patient and family burden were positively correlated mainly to Social Restrictiveness(Factor D). 4) Sex and religion of respondents showed no or weak relationship with the factor scores. Conclusions : Education for community leaders and families is required to achieve successful community mental health services. Community support program should be developed for chronic, recurrent and burdensome psychiatric patients in the first place.

목적 : 기관지내시경 검사에서 흔히 사용되는 국소마취제인 lidocaine과 내시경시 지혈목적으로 사용되는 thrombin과 epinephrine이 각종 균주에 미치는 항균효과에 대해 알아보고자 하였다. 재료 및 방법 : 균주는 가톨릭대학교 성모병원에서 2004년 3월부터 2004년 9월까지 임상검체 에서 동정된 S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa 각각 42, 42, 42, 43주를 대상으로 하였다. Lidocaine, thrombin, epinephrine 감수성 검사는 National Committee for Clinical Laboratory Standards (NCCLS, 2002)의 기준에 따랐다. 결과 : Lidocaine은 S. aureus, S. pneumoniae, P. aeruginosa에서 MIC_(50), MIC_(90) 모두 20,000 ㎍/mL 이었다. K. pneumoniae는 각각 10,000 ㎍/mL이었다. Thrombin은 S. aureus와 P. aeruginosa에서 MIC50 500 lU/mL 과 MIC_(90) 500 IU/mL 이상이었고, K. pneumoniae에서는 MIC_(50)과 MIC_(90)이 모두 500 lU/mL이상이었으나 S. pneumoniae에서는 MIC_(50)과 MIC_(90)은 125 IU/mL이었다. Epinephrine은 K. pneumoniae, S. pneumoniae에 대한 MIC_(50), MIC_(90)가 모두 >500 ㎍/mL이었고, S. aureus와 P. aeruginosa에 대한 MIC_(50), MIC_(90)가 모두 500 ㎍/mL이었다. 결론 : 기관지 내시경 검사에서 흔히 쓰이는 lidocaine, thrombin, epinephrine 등의 약제들이 호흡기 질환의 흔한 병원균인 S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa 균주들에 대해 항균 효과가 있을 수 있어 세균배양검사에 영향을 미칠 수 있겠다. Background : We performed this stody to find out about antimicrobial effect of lidocaine which is commonly used local anesthetic, and thrombin and epinephrine used for hemostasis during bronchoscopic procedures. Materials and Methods : The microorganisms that were cultured from specimens obtained during bronchoscopy were Staphylococcus aureus (n=42), Streptococcus pneumoniae (n=42), Klebsiella pneumoniae (n=42), and Pseudomonas aeruginosa (n=43) collected from St. Mary's Hospital, from March to Sep 2004 were used for susceptibity testing. Susceptibility to lidocaine, thrombin, and epinephrine were tested according to the National Committee for Clinical Laboratory Standards. Result : MIC_(50) and MIC_(90) of lidocaine for S. aureus, S. pneumoniae, P. aeruginosa were all 20,000 ㎍/mL and that for K. pneumoniae were 10,000 ㎍/mL. MIC_(50) and MIC_(90) of thrombin for both S. aureus and P. aeruginosa was 500 IU/mL and above 500 IU/mL, respectively; that for K. pneumoniae were all above 500 IU/mL and for S. pneumoniae they were 125 IU/mL, MIC_(50) and MIC_(90) of epinephrine for K. pneumoniae and S. pneumoniae were above 500 ㎍/mL; that for S. aureus and P. aeruginosa were 500 ㎍/mL. Conclusion : We observed possible antimicrobial effect of lidocaine, thrombin, and epinephrine in vitro against pathogens such as S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa, which are common respiratory microorganisms. The use of these agants could affect the result of bacterial culture.

국내 중증 만성정신질환자 수를 추정하기 위하여 일 농촌 및 대도시 지역의 지역의료보험 및 의료보호 대상자 중 1993년 1년간 의료기관에서 정신증 상병(ICD-9 code 상 290-299) 및 알콜 남용/중독, 성격장애 및 정신박약 진단하에 치료를 받은 적이 있는 사람에 대해 설문조사를 실시하였다. 연구자들이 개발한 진단도구를 이용하여 진단을 평가하고, Strauss-Carpenter scale 등을 이용하여 기능 장애를 평가하고 유병기간 등을 조사하였다. 결과를 요약하면 다음과 같다. 1) 진단평가상 정신분열병군(61.1%)이 가장 많았으며, 정동장애군(23.7%), 알콜장애군(11.2%), 기질성 정신장애군(4.0%)의 순서이었다. 2) 직업활동정도는 진단군별로 차이가 많았다. 지난 1년간 직업활동이 6개월 미만이거나 전혀 없는 환자 비율이 정신분열병군은 67.2%, 알콜장애군 52.0%, 정동장애20.8%의 순으로 정신분열병군이 가장 불량하였다. 3) 사회활동도 진단군별로 차이가 많아서 지난 1년간 의도적, 사회활동이 없는 비율이 정신분열병군이 가장 높았고(72.3%), 알콜장애군(32.0%), 정동장애군(20.7%)의 순이었다. 4) 국내 의료보험 및 사회복지시설 이용 자료 등을 토대로 본 조사 결과를 적용한 결과 국내중증 만성 정신질환자의 수는 약 8만 7천명으로 추산되었다. Objectives: The purpose of this study was to estimate the number of serious and persistent mentally ill patients in Korea. Methods : Study populations were recruited from medical insurance data of two district areas ; one rural and the other urban areas. Subject were all mentally ill who had ever visited any hospital in 1993 and were diagnosed as having psychosis, personality disorder and drug abuse. We conducted a home visiting survey applying semi-structured diagnostic interview, assessing the level of social adjustment with Strauss-Carpenter Scale, and past psychiatric history by the trained researchers, in October and November,1994. Results : According to diagnostic assessment schizophrenic patients constituted the major portion(61.1%) of study subjects. The distribution of occupational functions and social contacts was variable according to diagnosis. Most schizophrenic patients were unemployed or worked less than 6 months in the previous year(67.2%), and showed poor social contact(72.3%). But affective disorder patients were relatively independent in job maintenance and social relationship. Alcoholic patients lay between those of schizophrenic and affective disorder groups. It was estimated that about 87,000 adult Koreans were suffering from chronic mental disorders which seriously interfere with their daily life. Conclusions : Serious and persistent mentally ill patients were common in Korea. Community support program should be provided for them.

김진경,김기홍,김행미,안두홍 慶北大學校 醫科大學 1991 慶北醫大誌 Vol.32 No.1

신생아 시기에 BCG를 접종받은 영아를 대상으로 3±개월, 7-8개월 및 15-16개월에 Mantoux 검사를 시행하여 다음과 같은 결과를 얻었다. 3-4개월째 측정한 결절의 크기는 5.8±4.5㎜, 7-8개월째 7.9±4.9㎜,15-16개월째 6.7±4.9㎜로서 7-8개월째 의의있게 (p<0.55)증가되어 있었다. Mantoux 검사상 결절의 크기가 5㎜미만인 경우를 음성으로 간주하였을대 3-4개월째 38.5%, 7-8개월째 26.0% 및 15-16개월째 35.2%가 음성이었으며 15㎜이상의 강양성은 3-4개월째 1.9%, 7-8개월째 12%, 15-16개월째 7.5%를 차지하였다. 33례의 미숙아에 있어서 BCG 접종후 18개월 동안 5㎜ 이상의 반응을 보인 양전례는 63.6%인 21례로 이들 양전군과 비양전군 사이에는 출생시 제태연령, 체중 및 BCG 접종시기에 유의한 차이를 보이지 않았으며 만삭아의 양전율과 비교 하였을 때 의의있는 차이를 보이지 않았다. We conducted this study to evaluate the change of tuberculin reaction after neonatal BCG vaccination in Korea. Seventy-four infants were followed for 15-16 month after birth. BCG vaccination were given within 4 weeks after birht and 3 times of Mantoux test were performed at 3-4 months, 7-8 months and 15-16 month after birth. During the same period, Mantoux test were done on 238 cases of 3-4 months-old infants, 107 cases of 7-8 months-old infants and 85 cases of 15-16 months-old infants who were given BCG vaccination within 4 week after birth. We evaluated the results without distinction of these infants because there was no statistically significant difference between two groups. The size of induration was significantly increased at 7-8 months(7.9±4.9㎜) compare to the size at 3-4 months (5.8±4.5㎜) and 15-16months(6.7±4.9㎜) (P<0.05). But 38.5%, 26.8% andn 32.5% of infants were not converted ( < 5㎜) at 3-4months, 7-8 months and 15-16 months after birth respectively. Thirty-three preterm infants were followed for 18 months after birth. Twenty-one out of 33 (63.6%) were converted during this period. There was no difference of gestational age, birth weight, age on BCG vaccination between converters and nonconverters. There was no difference of conversion rate compatre to full term infants.
