法定代理와 민법 제126조의 관계

박철호(Park, CheolHo) 한양법학회 2009 漢陽法學 Vol.25 No.-

The problem is that whether delegation of legal power only happened by a legal act is recognized as a foundation the right of agency to be permitted and especially, agency provided by law is recognized as a foundation the right of agency. The right problem is that whether it can be applied by the section 126 that the procuration of conjugal household and the subrogation of a guardian of a person without legal capacity are provided by the section 827 of Korean civil law. Case law has solved whether the representation agency provided by the section 126 of Korean civil law can be applied by using transaction security. Of course, it is true that court try to make right application of rigid rules through "lawful reason", but case law say that there are no reason to judge differently both agency provided by law and discretion agency by the section 126 of Korean civil law. In case of procuration of conjugal household, case law can have validity in effect. But, in case of a guardian of a person without legal capacity, it is not matched to the basic of representation agency that a person without legal capacity is imposed on his/her responsibility for guilty to recognize a foundation the right of agency for the completion of representation agency. And also that is not matched to the principle of self-determination and self-responsibility that is based on a basis validity of legal act. And more, a guardian of a person without legal capacity should accept that there are other requirements of decision rather than realization of the law of logic. Examine the regulation of a family council of Korean civil law, there are reasons that we should accept. In effect that is kind of a formal act and we should consider it has the lack of ability to control. Accordingly, in case of agency provided by law of a person without legal capacity, the problem that whether the expression of procuration should be rightful should not be applied and also case law should be interpreted in limited ways.

박철호 ( Cheolho Park ),김준형 ( Junhyung Kim ) 한국부동산분석학회 2023 부동산분석학회 학술발표논문집 Vol.2023 No.1

부동산경매 낙찰가율에 미치는 영향에 관한 많은 연구가 진행되어 왔다. 특히 주거용 부동산 경매에 대한 연구가 많이 진행되어 왔지만 상업용 부동산 경매에 대한 연구는 부족한 실정이다. 상업용 부동산 경매 낙찰가율에 미치는 영향 요인 중 인구와 소득이 유의미한 영향이 있는지 연구하고자 한다. 공간적 범위는 서울의 5개 법원으로 하고 시간적 범위는 2018년1월부터 2022년12월까지 낙찰된 상업용 부동산경매 물건 중 집합건물의 소유 및 관리에 관한 법률에 따른 구분소유 상가경매 물건으로 하였다. 총1,125건 중 20㎡미만의 소형 상가와 테마상가, 현황상 주거용으로 이용하는 근린생활시설 등을 제외한 451건으로 분석하였다. 분석모형으로는 헤도닉가격모형으로 하였다. 종속변수는 낙찰가율로 하고, 독립변수는 인구특성, 소득특성, 물리적특성, 경매특성, 입지특성으로 하였다. 인구특성에는 주거인구, 직장인인구, 유동인구로 하고 소득특성에는 연소득(주거지), 연소득(근무지)으로 하고, 물리적 특성으로는 전용면적, 경과년수, 층수로 하고 경매특성으로는 입찰자수, 유찰횟수, 유치권신고여부, 지분경매 여부로 하고 입지특성으로는 지하철역과의 거리로 하였다. 분석결과 주거인구와 유동인구가 다중공선 성의 문제가 발견되어 주거인구를 제외하고 다시 분석한 결과 유찰횟수만 음(-)의 영향을 주는 결과를 보였고 다른 독립변수들은 유의미하지 않은 결과를 보였다. 이후 연구를 통해 인구와 소득이 상가경매 낙찰가율에 미치는 영향에 대한 상관관계를 밝히고 의미있는 분석결과를 도출하고자 한다.

상장리츠의 수익, 위험, 그리고 재무적 특성: 2010~2015

This article examines the risk-return characteristics of Real Estate Investment Trusts (REITs) listed on the Korea Exchange (KRX) from 2010 to 2014, a period of stagnant growth in the real estate and equity markets. Two indexes composed of publicly traded REITs have slightly higher returns, risk and Sharpe ratios relative to the KOSPI200 equity index but lower returns, higher risk and lower Sharpe ratios relative to the KRW Cash government bond index. The REITs also have weak positive correlations with the equity index but weak negative correlations with the government bond index, illustrating their diversification potential within the framework of a mixed-asset portfolio. We employ the Sharpe-Lintner CAPM, the Fama-French three-factor model and the Carhart four factor model to measure REITs` exposure to systematic risk factors and evaluate their risk adjusted performance. Overall, the market premium alone appears to have statistically significant effects on the excess returns of REITs. Self-managed REITs with more volatile prices and lower dividend yields tend to have higher beta coefficients. Finally, we look into correlations between REITs` financial metrics and their systematic and unsystematic risks. Results show that the interest coverage ratio, market capitalization and dividend yield have moderate to strong negative correlations with unsystematic risks whereas the interest coverage ratio and market capitalization have moderate negative correlations with the beta coefficient. This finding underscores the importance of factors such as business profitability and stability when managing or investing in REITs.

Today the advancement of life scientific technique contributed it solves a sterility effectively. It does so, it is this possibility of the artificial pregnancy such as the Artificial Insemination, the in vitro fertilization-embryo transfer, the gamete intrafalopian transfer etc. The birth of the child who leads the surrogate mother became accomplished. But the surrogate mother contract appears and the problems which forecast it cannot entirely before are proposed, There is to surrogate mother contract, the surrogate mother and the client where becomes the mother legally changes. The problem of many law will be able to occur. Each nations are taking the position which differs each other in about permission and prohibition of surrogate mother system. However the surrogate mother occurs from all countries, the nation which permits a surrogate mother contract or the nation which forbids a surrogate mother contract. Our country is not legal provision to about the surrogate mother contract. It does to entrust in interpretation of civil law. The legal interpretation as a matter of surrogate mother contract violates in the 103 provision of civil law. And so, the multiple position as invalidity thought a surrogate mother contract.

자동차의 경량화를 위해 요구되는 철강의 강도가 높아지면서 수소 지연 파괴가 드러나고 있다. 수소취성 감수성은 철강의 강도에 따라 증가하며, 특히 약 1,000MPa 이상인 고강도 강의 경우 일정 시간이 지나면 수소취성에 의한 균열이 발생하여 갑자기 절단되는 지연파괴(delayed fracture)가 일어난다. 특히 차량 구조부 고강도 강에 수소취성이 발생한 상태에서 충돌이 발생하는 경우 심각한 사고가 될 수 있다. 수소취성 가능성을 예측하고자, 도금유무에 따른 수소확산 거동을 측정하였으며, 핫스탬핑 전과 후의 미세조직의 변화 및 수소확산거동 차이를 확인하였다.

중국 CSI 300 주가지수에 대한 MACD 거래전략의 수익성

박철호(Cheolho Park) 중앙대학교 한국전자무역연구소 2023 전자무역연구 Vol.21 No.1

연구목적: 본 연구의 목적은 2012-2021년 기간의 중국 CSI 300 주가지수에 대해 MACD 거래전략의 수익성을 분석하는 것이다. MACD(moving average convergence- divergence)는 기술적 지표의 일종으로 여러 금융시장에서 가격 예측을 위한 기술적 분석(technical analysis)에 흔히 사용된다. 기술적 분석은 가격의 추세나 패턴을 이용하여 미래 가격 움직임을 예측하는 방법이며, 실무에서는 펀드운용자들이나 투자자들에 의해 널리 활용되고 있다. 학술적으로 기술적 분석은 약형(weak-form) 효율적 시장가설을 검증하는 수단으로 사용되고 있다. 논문구성/논리: 수익성 측정을 위해 MACD를 구성하는 4가지 파라미터 조합으로부터 18,221개의 방대한 거래규칙을 생성하고, 순수익률과 샤프비율 기준 하에서 이들의 거래성과를 매입보유전략의 성과와 비교한다. 먼저, 10년의 전체 기간과 각 5년의 두 하위기간에서 가장 우수한 MACD 거래전략이 매입보유전략보다 더 좋은 거래성과를 내는지 살펴본다. 다음으로, 투자자들이 실제로 활용할만한 분석방법으로 과거 일정 기간의 자료에 MACD 거래규칙들을 최적화하고, 각 기간에서 가장 우수한 성과를 보인 거래규칙을 다음 1년 동안의 거래에 적용하여 그 성과를 측정한다. 결과: 각 성과기준 하에서 전체 및 하위 분석기간 동안 MACD 거래전략은 매입보유전략에 비해 훨씬 높은 성과를 거둔 것으로 나타났다. 전체 분석기간에서 MACD 거래전략의 연평균 순수익률과 샤프비율은 각각 13.75%와 0.556이었으며, 이는 매입보유전략의 상응하는 성과인 7.45% 및 0.283과 비교된다. 특히, 첫 번째 하위기간인 2012-2016년 기간에서 MACD 거래전략은 매입보유전략보다 3배 이상 높은 순수익률(연 23.14%)과 4배가량 높은 샤프비율(0.853)을 기록하였다. 최적화 방법을 사용한 표본 외 분석에서도 과거 1년 간의 자료에 최적화된 MACD 거래규칙들은 2021년을 제외한 나머지 9년의 기간에서 모두 양(+)의 순수익률을 거두었으며, 연평균 순수익률과 사프비율은 각각 9.57%와 0.372로 매입보유전략보다 각각 연평균 2.12%, 0.089 높은 것이다. 독창성/가치: 본 논문은 국내 문헌으로서는 처음으로 대표적 추세추종 지표인 MACD를 중국 주식시장을 대표하는 CSI 300 주가지수에 적용하여 그 효과성을 분석하였다는 데 의의가 있다. 방법론적으로, 본 논문은 18,000여 개가 넘는 거래규칙들을 다양한 기간에 걸쳐 최적화하고, 이를 통해 얻는 최적 거래규칙을 이후의 분석기간에 적용하여 그 수익성 여부을 살펴보았다. 국내에서도 중국 주식시장과 관련된 다수의 수익증권과 상장지수펀드(ETF)가 활발히 거래되고 있다는 점에서 본 논문의 연구결과는 실무적으로도 시사하는 바가 크다. Purpose: This study analyzed the profitability of the MACD trading strategy for the Chinese CSI 300 stock index from 2012 to 2021. MACD is a technical indicator commonly used in technical analysis for price prediction in various financial markets. Technical analysis is a method of predicting future price movements using price trends or patterns and is widely used by fund managers and investors. Academically, technical analysis is used as a means of testing the weak-form efficient market hypothesis. Composition/Logic: To measure profitability, 18,221 trading rules were created from the four parameter combinations that make up the MACD, and their performance was compared with that of the buy-and-hold (B&H) strategy under the criteria of the net return and Sharpe ratio. First, we determined whether the best MACD strategy outperformed the B&H strategy over the full 10-yr period and each of the two five-yr sub-periods. Next, MACD trading rules were optimized for the data of a certain period in the past, and the trading rules that showed the best performance in each period were applied to transactions for the next year to measure their performance. Findings: Over the full sample period, the average annual net return and Sharpe ratio of the MACD trading strategy were 13.75% and 0.556, respectively, compared to the corresponding performance of the B&H strategy of 7.45% and 0.283. In the first sub-period, from 2012 to 2016, the MACD trading strategy recorded a net return that was three times higher than that of the B&H strategy and a sharpe ratio that was four times higher than that of the B&H strategy. Even in the out-of-sample analysis using the optimization method, the MACD trading rules optimized for the previous year achieved positive net returns in all nine years except for 2021 and outperformed the B&H strategy. Originality/Value: This study is significant in that it analyzed the effectiveness of the MACD for the first time in Korean literature by applying it to the Chinese CSI 300 stock index. Methodologically, we optimized more than 18,000 trading rules over several in-sample periods and applied the optimal rules to the subsequent period to see whether they were profitable. The findings in this study have great practical implications in that a number of beneficiary certificates and exchange-traded funds related to the Chinese stock market are also actively traded in Korea.

원치 않은 출산소송에 관한 판례평석

박철호(Park, CheolHo) 한양법학회 2012 漢陽法學 Vol.23 No.1

Wrongful birth describes a cause of action or claim by parents of a deformed or defective child who allege that negligent advice as to the risk of genetic or birth defects or negligent treatment, or failure to abort a fetus, by the doctor deprived them of the choice of avoiding the child’s conception or of terminating the pregnancy. In these cases, parents of child with disability allege that because the defendant doctor breached the duty owed to the patient, they were denied the opportunity to make an informed decision. This claim lies on the basis that had it not been for the doctor’s negligence, the imperfect child would not have been born. In traditional medical malpractice lawsuits doctor’s negligence is the direct cause in the child’s disability, but in wrongful birth cases his/her negligence are the indirect causes of child birth. After this new type of lawsuit like wrongful birth action had been litigated in the United States in the 1930s many courts in Germany, France, UK including the United States have been recognized to recover to the parents for birth of child with disability. In contrast, in Korea, wrongful birth actions have been brought by parents alleging that the physician’s negligence of their child caused the injury in 1990s in many lower court and since that time these have been big issues legally and socially. While some lower courts have recognized in this new type cause of action, others have rejected it based on the difficulty in determining damages. On the other hand the Supreme Court of Korea has generally indicated negative attitude to the cause of wrongful birth action. However, Korean Supreme Court, for the first time as the highest Court, had decided to recover to parents of children with disabilities for the mental damages excepting for property damages in 2002. After this 2002 Supreme Court decision because there are only one judgment in Seoul Western District Court it can not be said that many wrongful birth actions will be brought sooner or later. But in a long-term perspective it can be said that this new type actions will be gradually increasing in Korea. It was apparent that Korean Courts still had a negative view to the cause of wrongful birth action. But because the Supreme Court’s 2002 decision agreeing to allow the parents of disabled child to recover damages for the mental anguish was said rather progressive, it may seems to be a positive outlook on this issue. Meanwhile many courts of Korea have determined whether it can allow the parents of disabled child to recover damages, basing on Article 14 of Maternal and Child Health Act, allowance standard of abortion. When the abortion of the disabled fetus only can be allowed depending on Article 14 of Maternal and Child Health Act, Courts allowed damages to the parents of children with disabilities. But this Article 14 has been designed to allow abortion because of the health of the parents and this is just standard to judge whether the maintenance of pregnancy is harmful to the health of the mother of fetus. Therefore, it is unreasonable that it should be decided to recover the damages to the parents in wrongful birth action whether or not to admit by the Article 14 of Maternal and Child Health Act. Thus, the court should change their views. So it should be decided to recover the damages to the parents in wrongful birth action because of the doctor’s negligence, the duty violation doctor’s explanation and the health of the fetus itself. In this paper, it was reviewed the Supreme Court’s 2002 decision, investigated about whether or not to admit demage recover in this type of action, and examined the compensation range.
