In order to capture the fast crack propagation in an unmanipulated concrete fracture test, we employed mechanoluminascent(ML) material, which emits visible light when stressed, as a crack visualization tool. Three-point bending fracture test setup, a paint type ML material and a high speed camera were used to capture the images of fast moving cracks. The maximum size of coarse aggregates of concrete was used as an experimental parameter. The crack images, loading, and crack mouth opening displacement were successfully recorded as a function of time elapsed. From the test results, several interesting cracking behavior in the unmanipulated fracture test was observed in such that (1) the crack moves fast while the load is slowly decreased after the maximum loading, and (2) the crack in concrete with larger coarse aggregates moves faster than the others.

Tuberculosis of the nasal cavity and nasopharynx is extremely rare. The diagnosis is frequently delayed because of unfamiliarity with the disease. It is difficult to make an accurate diagnosis of tuberculosis of the nasal cavity and nasopharynx on imaging findings alone; a biopsy is required to confirm the diagnosis and to differentiate it from malignancy and the other conditions. The authors have experienced 6 cases of tuberculosis of the nasal cavity and nasopharyx. We report them with review of literatures.

국내 주식시장에서 시장 유동성과 모멘텀 효과에 관한 연구

이창준,김창하 한국파생상품학회 2018 선물연구 Vol.26 No.4

Previous literature in the Korean stock market has shown that the momentum effect is not observed during pre-2000 period while it is observed during post-2000 period. Given that market illiquidity has substantially decreased during post-2000 period, we examine whether the level of market illiquidity affect the momentum profits. The central findings are summarized as follows. First, our full-sample analysis shows that market liquidity is positively associated with momentum profits, meaning that the observed momentum effect during post-2000 period is related to the decrease in market illiquidity. Second, during pre-2000 period, when the market illiquidity is very high, the illiquidity of past losers is extremely high compared to that of past winners. However, there is no significant difference in illiquidity between winners and losers during post-2000 period. Third, based on this result, we conjecture that the momentum effect is related to the different compensation for liquidity risk between past losers and winners, and test whether this is indeed the case. We find significant momentum profits over the whole period when we consider the compensation for the liquidity risk of past losers and winners. In addition, during pre-2000 period, the return on momentum strategy that controls the liquidity risk is substantially higher than the actually observed momentum profits. In sum, our study suggests that the difference in compensation for liquidity risk between past losers and winners is very important in understanding the momentum effect in the Korean stock market. 국내 주식시장에서 모멘텀 현상을 살펴본 최근 연구들에 의하면, 2000년 이전에는 모멘텀 현상이 관찰되지 않지만, 2000년 이후에는 모멘텀 현상이 강하게 나타남을 보고하고 있다. 이에 본 연구에서는 시장 유동성과 모멘텀 수익률의 관계를 통해 국내시장에서 2000년을 기준으로 모멘텀 현상이 서로 다른 양상을 보이는 이유를 분석하였으며 주요 결과는 다음과 같다. 첫째, 시장 유동성은 모멘텀 효과와 강한 양의 관계를 나타내는데, 이는 2000년 이후에 모멘텀 현상이 관찰된 원인이 시장 비유동성의 감소와 관련이 있음을 암시한다. 둘째, 시장의 비유동성이 높은 2000년 이전에는 10분위 모멘텀 포트폴리오의 유동성 수준이 매우 다르며 과거 패자(승자)의 비유동성(유동성)이 높은 현상이 관찰되지만, 2000년 이후에는 과거 승자와 패자 사이에 유의미한 유동성 차이가 존재하지 않았다. 셋째, 과거 승자와 패자 포트폴리오의 유동성 위험에 대한 보상을 고려할 경우 전체 기간에서 통계적으로 유의한 모멘텀 현상을 발견할 수 있었다. 본 연구는 과거 패자와 승자의 유동성 요인에 대한 보상의 차이가 국내 주식시장에서 모멘텀 현상을 이해함에 있어 매우 중요한 요소임을 보고한다.

This research describes how to predict a model of the tensile strain related to the fatigue cracking performance of several asphalt concrete structures through design of experiments(e.g., Response Surface Methodology) and harmony search(HS) algorithm. The axisymmetric analysis program of finite element method, which is the KICTPAVE, was used to determine the strain level at the interface layer between asphalt layer and lean concrete layer. Once the training database set of various strain levels was constructed under the several condition of layer stiffnesses and thicknesses in the asphalt concrete structures, the data set was trained through the HS algorithm in order to determine the regression coefficients defined based on a response surface methodology. Furthermore, the testing set, which was not used for the training procedure of HS algorithm, was also constructed in order to evaluate whether the regression coefficients of a prediction model can be appropriately applied for other cases in asphalt concrete structures. 본 연구는 실험계획법(예: 반응표면계획법) 및 하모니 검색 알고리즘을 통하여 다양한 아스팔트 콘크리트 포장 구조체에 있어 피로균열의 공용성 인자인 인장변형률을 예측하는 모델을 개발하는 방법에 대한 연구이다. 인장변형률을 산정하기 위하여한국건설기술연구소에서 개발한 유한요소 축대칭해석 프로그램인 KICTPAVE를 이용하여 아스팔트 층과 린콘크리트 층의 접속면에서 발생되는 변형률을 구하여 데이터베이스(D/B)화 하였다. 아스팔트 포장에서 입력변수인 층별 탄성계수 및 두께를 다양한 조건에서 KICTPAVE 프로그램을 수행하여 훈련용 D/B(Training Set)인 변형률의 값들을 구축한 후 반응표면계획법에근거하여 회귀방정식을 정의하였으며 방정식에 필요한 계수값을 결정하기 위하여 하모니 검색 알고리즘을 이용하였다. 최종적으로 결정된 회귀방정식의 계수값들의 정확성을 검증하기 위해서 훈련용 D/B가 아닌 다른 조건의 입력변수를 이용하여 검증용 D/B(Testing Set)를 구축하고 이를 이용하여 개발된 모델을 검증하였다.
