Much effort has been carried out to calibrate and revise asteroseismic relations, given their importance of relations in asteroseismology in determining fundamental parameters of stars. In this study, we statistically explore asteroseismic relations with partial correlation coefficients to determine the most fundamental parameters, separately analyzing asteroseismic data based on the evolutionary status of stars from main sequence up to core helium-burning red-clump stars. We have found that regardless of the evolutionary status of the sampled stars the surface gravity and density of stars strongly influence the observed correlations. More importantly, it is found that indirect correlations derived considering the influence of confounding parameters are subject to the evolutionary status. For example, the observed correlation of the large frequency separation Δν with the central frequency νmax is influenced by the stellar mass, radius, and luminosity only for main sequence stars. The observed correlation of the width of the Gaussian envelope δνenv with νmax is influenced by the stellar mass, effective temperature, radius, and luminosity for main-sequence and subgiant stars. The observed relation between Δν and the small frequency separation δν02 is influenced by the stellar mass, radius, and luminosity for main-sequence and subgiant stars. In contrast, effective temperature, metallicity, and age do not seem to significantly affect the observed correlations. Finally, we conclude by discussing implication of our findings.

In order to apply indirect methods (such as scaling factors) to assess the radionuclide inventory of waste generated by nuclear power plants, it is essential to first evaluate the correlation coefficient between key radionuclides and those that are difficult to measure (DTM). The benchmark for the correlation coefficient (r) applied in indirect assessments is set at 0.6, and its significance can vary based on both its value and the size of the dataset. For instance, deriving a correlation coefficient using three data points versus utilizing a dataset with a hundred data points would yield different implications. This study addresses the variance in correlation coefficients based on data selection and presents a methodology for validating the significance of these coefficients. Additionally, we will discuss how these variances may impact the results of indirect assessments, such as scaling factor evaluations.

영화에서 사용되는 오페라의 음악 및 줄거리는 유사성을 통하여 의미를 강화하고, 극적 전개에 기여한다. 오페라가 영화에 사용되면 그것은 분명 내재적 음악에 해당하나, 세련된 의미 전달과 강화를 위해 영화 제작자들은 영화 속 오페라의 위치성을 조작하여 현장감(청각적 충실도)을 성취하거나, 그와 반대로 처리하여 외재적으로 변용하기도 한다. 이 논문에서는 필자는 음악의 현장감을 확보하거나 무마하기 위해 위치성을 강화하거나 약화시키는 요인으로 음원의 명료성과 좌우 혹은 중앙의 방향성을 분석하였다. 전자는 위상상관계수, 후자는 고니오미터를 통해 계측이 가능한데, 필자는 영화에 사용된 두 요소의 미묘한 조정이 영화의 의미 형성 및 강화에 어떻게 기여하고 또 나아가 내러티브 전략을 보조하는 측면을 논의하였다. 필자는 『대부3』(1990), 『007: 퀸텀 오브 솔라스』(2008), 『미션임파서블 5 로그네이 션』(2015)에서 사용된 오페라 ⪡카발레리아 루스티카나⪢, ⪡토스카⪢, ⪡투란도트⪢가 음향의 변화에 따라 어떻게 기능하는지 위상상관계수와 고니오미터를 통해 분석하였다. 『대부3』에서는 오페라의 특정 지점에서 위상상관계수를 높여 가사를 대사 수준의 명료하게 확보하는 처리가 돋보였고, 『007: 퀸텀 오브 솔라스』에서는 근본적으로 내재성을 지닌 ⪡토스카⪢가 외재적으로 삽입 된 아놀드의 음악과 결합하며 만들어내는 위치성의 변화를 통한 역동적인 현장감 확보와 매체 간 감정 공유 방식이 드러났고, 『미션임파서블 5: 로그네이션』에서 음악의 처리 방식과 방향성 및 음향 조절을 통한 현장감 전달 방식을 확인할 수 있었다. 이러한 음향 조절은 영화음악이 내재와 외재의 위치성을 넘어 앰비다이제틱하거나 메타다이제틱한 음향 효과를 보조함으로써 관객들의 감정적 만족도와 풍요로운 정보로 인한 몰입도를 확보할 수 있음을 확인하였다.

In this study, we were turning STD11 and was carried out to presume for mutual relation of turning condition to get optimum cutting force(principal, radial, feed force) and experimental equation by variance, correlation coefficient and multi regression analysis with whisker reinforced ceramic tool. To predict cutting force, analyze principal, radial, feed force with multi-regression analysis. Results are follows: From the analysis of variance, affected factor to cutting force feed rate, depth of cut, cutting speed in order and cutting speed was very small affect to cutting force. From multi-regression analysis, we extracted regression equation and the coefficient of determination(R2) was 0.84, 0.88, 0.7 at principal, radial and tangential force. It means regression equation is significant. From the experimental verification, it was confirmed that princial, radial and tangential force was predictable by regression equation. Through the analysis of the correlation coefficient between each component forces and surface roughness, the principal force was found to have the greatest impact

화장품을 바를 때 피부와 손가락 사이에서 일어나는 마찰계수는 화장품의 주관적 평가에 많은 영향을 주는 요소이다. in-vivo상태에서 피부와 접촉자 간의 마찰계수는 접촉자의 모양이나 거칠기의 정도 그리고 누르는 하중에 따라 변할 수 있다. 본 실험에서는 리니어 모터와 다축 로드셀을 이용하여 여러 가지 접촉자를 in-vivo상태에서 직접 피부에 접촉시키고 실시간으로 마찰계수를 측정할 수 있는 장치를 개발하였다. 이 장치를 이용하여 피부와 접촉자 간의 마찰계수를 측정하고 그 데이터를 화장품을 바를 때의 전후와 비교·분석하였다. 또한 화장품을 바를 때 주관적인 평가에서 이용되는 형용사를 조사하며 마찰계수와의 그 상관관계를 분석하였다. 그 결과, 피부와 접촉자 간의 마찰계수는 화장품의 종류와 접촉자의 성질에 따라 0.17-1.2사이에서 나타나며, 주관적인 평가 또한 화장품을 바른 후 시간의 경과함에 따라 변하며, 그것은 마찰계수와 관련이 있음을 확인할 수 있었다.

A highly significant positive correlation was found between flowering date and maturing date, plant hight and ear length, number of pods per ear and flowering date, maturing date and plant hight, The number of seed per pod showed also significant positive correlation with flowering or maturing date as well as with the relationship between weight of 1, 000 grains and plant height or ear length inrapeseed, respectively. Heritabilities of maturing date, length of stem with eapsule and number of seed per capsule were high, in sesame.
