切斷者의 再活에 關한 硏究

申廷淳,權純元 中央醫學社 1977 中央醫學 Vol.33 No.6

We have made a study of 1, 235 amputees (1, 342 limbs) who were admitted to the Rehabilitation Center, Yonsei University Medical Center to have prosth-etic fitting and training during the period from March 1970 to February 1975. The age groups of the amputees in order of prevalence were 21 to 30 years, 11 to 20 years and 31 to 40 years. Males accounted for 85.4% of the cases and females 14.6%. Accidents were the cause of the greatest number of amputations (78.1%) with peripheral vascular diseases next in 9.7%. Lower extremity amputations accounted for 77.3% of all the cases. Of these,, 399 cases (38.4%) were A.K. amputations and 528 cases (50.8%) were B.K. amputations. The remaining 22.7% of the cases were upper extremity amputations. Of these, 112 cases (36.8%) were A.E. amputations and 143 cases (47.0%) B.E. amputations. In general most of the amputees were poorly educated and 87.1% came from economically very poor families thus necessitating governmental relief and charity service for their rehabilitation.

KOSPI 상장 기업의 스프레드 추정 방법론 연구

신정순,임예진 한국자료분석학회 2015 Journal of the Korean Data Analysis Society Vol.17 No.4

본 연구에서는 스프레드 연구와 관련하여 일일 고가와 저가 정보로부터 스프레드를 추정하는 Corwin, Shultz(2012)의 스프레드 추정방법론이 국내에도 적용가능할지 그 적용가능성에 대하여 살펴보았다. Corwin, Shultz(2012)는 일일 고가(저가)는 대부분 매수(매도) 거래이므로 고가-저가 비율은 주식의 변동성과 스프레드를 반영한다는 점에 착안한 스프레드 추정법을 제안하였다. 이들의 추정방법에 따라 국내 주식 시장에 상장되어있는 KOSPI 200 기업 데이터를 활용하여 연구한 결과, 추정법의 국내 주식 시장 적용 상 중대한 문제점들이 관찰되었다. 먼저 스프레드 값은 음수를 가질 수 없음에도 불구하고 추정한 스프레드율 값을 살펴보면 전체 표본에서 음의 스프레드율의 비율이 상당히 크게 나타났다. 또한 실제 거래소에서 제공한 KRX스프레드율과의 비교에서도 호가 단위별로 어느 정도의 차이는 존재하였지만 전체 표본으로 고려할 때 HL스프레드율과 KRX스프레드율의 상관계수가 4%에 불과해 이들의 추정 방법론은 국내 시장에서 적합하지 않은 것으로 나타났다. This paper analyzes the applicability of the high-low spread estimator developed by Corwin, Shultz (2012) to daily and low prices in the Korean stock market. Corwin, Shultz (2012) suggested the bid-ask spread estimator which is based on the idea that daily high (low) prices are almost buy (sell) trades, and therefore the high-low ratio reflects both the variance of stock and its bid-ask spread. We investigate the spreads of firms listed in KOSPI 200 which are based on the estimating method of Corwin, Shultz (2012), then find out the critical problems. The results show that the proportion of spreads have negative value which is considerably high although spread cannot be negative. Though slight difference of correlated coefficients between HL spread ratio and KRX spread ratio does exist when considering them as tick range, it is only about 4% as a whole. This shows that the High-Low spread estimator is not an appropriate estimating method of spread in Korean financial market.

Security Concentration and Fund Performance

신정순,손판도,김성신 한국증권학회 2011 Asia-Pacific Journal of Financial Studies Vol.40 No.1

We examine focused funds from 2002 to 2008 to see whether they offer superior performance to Korean equity funds without survivorship bias. Prior studies show that fund managers might allocate their funds to specific industries or focused securities to achieve superior performance. However, after controlling for various fund characteristics and using several alternative measures, our results show that fund performance has a positive relation to diversification. Furthermore, we identify that the underperformance of focused funds is due to liquidity problems, idiosyncratic risk, and trade performance. Our findings have important implications for the investment strategies of fund managers and fund industries.

Analysis of Transaction Costs and Inferring Trade Direction

신정순 한국자료분석학회 2009 Journal of the Korean Data Analysis Society Vol.11 No.4

Using the U.S. TAQ(Trading and Quotation) data, I analyzed the transaction costs and inferred the trading direction. Unlike the explicit trading costs, little attention has been paid to the implicit trading costs. In the market microstructure study, absolute, effective, and realized spreads are deemed as the implicit costs. To obtain the effective and realized spreads, I employ the Lee and Ready(1991) 5 second rule method. Then, I compare three implicit costs. Consistent to the theory, effective and realized spreads show the lower values than the absolute dollar spreads. Effective spreads reflect the price improvement because dealers and brokers provide discount to the traders. Realized spreads adjust for the price impact since large buys and sales may have influence on the prices following block transactions.

금융기업 경영진 보수체계에 대한 시사점 및 사례 분석

신정순,오원선 예금보험공사 2009 金融安定硏究 Vol.10 No.2

The purpose of this study is to examine the current problematic executive compensation system in financial corporations, to analyze the causes of the situation, and to propose some effective solutions. Even though the managers of financial corporations are often expected to take the initiative to take a lead in overcoming the current global financial crisis, they are still sticking to excessive and short-term performance based incentives by shirking their sense of mission and responsibility. In this study, we suggest four major factors of the rampant malpractice of financial corporations, and perform a case analysis of Sam Sung Card to propose a key solution to make up for the weak points of the current incomplete compensation system. Unfortunately, we were however unable to observe the high executive compensation level as suggested by previous studies. The compensation level of ten Korean financial corporations for the year 2008 is similar or lower than those of non-financial corporations. It is likely that the result might have been under-calculated by only focusing on compensation paid in cash and not considering the amount of stock options. Thus, stock options paid to the managers of financial corporations should be included in any further research. 본 연구의 목적은 금융기업 경영진의 보수체계의 현실과 문제점을 살펴보고 그에 대한 원인분석과 효과적인 해결책 제시에 있다. 글로벌 금융위기가 장기화되고 있는 오늘날의 상황에서, 사실상 사명감과 책임의식을 가지고 위기극복에 앞장서야 할 국내외의 금융기업 경영자들은 여전히 단기성과 위주의 보너스 및 성과급을 과다 지급하는 등 비도덕적 관행을 고수하고 있다. 본 연구에서는 이러한 금융기관의 경영부실화 사태 및 경영자들의 도덕적 해이의 업무행태의 원인에 대하여 크게 네 가지 사항을 제시하고, 현재의 미흡하고 불완전한 현재의 보상체계를 보완할 수 있는 효과적인 해결책을 제시하기 위해 삼성카드의 사례를 분석하였다. 그러나 본 연구에서는 2008년의 국내 금융기업 10곳의 경영진의 보수를 조사한 결과 비금융기업들에 비해 금융기업이 비교적 낮은 수준의 경영진 보수를 지급한 것으로 밝혀져, 금융기업의 고임금 문제현황을 다루고 있는 기존의 국외연구와는 사뭇 다른 결과를 나타냈다. 이는 본 연구에서 스톡옵션 지급액은 고려하지 않고 현금지급액만을 기준으로 경영진 보수를 산정했기 때문으로 보이며, 앞으로의 연구에서는 스톡옵션에 대한 연구가 추가적으로 진행되어야 할 것으로 보인다.

Enflurane 마취환자의 간기능 검사에 관한 연구

신정순,노영순 대한마취과학회 1983 Korean Journal of Anesthesiology Vol.16 No.2

The controversy over the hepatotoxic effect of the halogenated anesthetic agents, particullary halothane, is still not resolved despite many years of continued study. Enflurane (synthesized by R. Terrell In 1963) reduces the potential for hepatotoxic effects as compared to some fluorinated agents because of a relatively low level of biotransformation, but liver injury following enflurane anesthesia has been reported, and was attributed to hepatotoxic agents, upper abdominal surgery, blood transfusion, shock, hyperpyrexia and sepsis. This study was undertaken to evluate the effect of enflurane on liver function by comparing the preoperative and the 48 hour postoperative liver function tests in 25 cases of enflurance and also in 20 cases of balanced anesthesia. Other factors considered were the influences of the duration of anesthesia, the type of surgery, and the use of blood transfusion. The results were as follows; 1) SGOT and SGPT levels were significantly increased in enflurane group; but SGOT were increased above the normal range, on the other hand SGPT were remained within normal limits. 2) SGOT and SGPT levels were increased significantly in the balanced anesthetic group; but SGOT were increased above the normal range, on the other hand SGPT were remained within normal limits. 3) SGOT and SGPT levels were significantly increased following prolonged anesthesia of 3 hours. 4) SGOT and SGPT levels were significantly increased after gastric surgery. 5) SGOT and SGPT levels were significantly increased after blood transfusion. 6) But the other values of the liver function test, such as alkaline phosphatase, total bilirubin and total protein were not significantly increased and remained within normal limits. Although minute changes in liver function were occured following enflurane anesthesia, it is suggested that the changes in liver function were more influenced by the duration of anesthesia the type of surgery and the administration of blood rather than the kinds of anesthetic agents.
