  • The purpose of this study was to examine the mediating effect of the adult attachment in the relationship between the family of origin functioning and fear of intimacy. Data were collected through a questionnaire from 557 university students in the Jeollabuk-do of South Korea. The collected data were analyzed by basic descriptive statistics, Pearson's correlations and multiple regression analysis. Baron and Kenny's method was used and examined, and the Sobel test was performed to determine the mediating model's significance. It was adapted to SPSS ver. 18.0 for Windows. The major findings were as follows: first, the functioning of family-of-origin was negatively related to the fear of intimacy. In addition, younger students and students with less past dating experience were more likely to fear of intimacy. Second, fear of intimacy was influenced by the family-of-origin through the intermediate effect of attachment avoidance and attachment anxiety. Attachment avoidance and attachment anxiety had partial mediating effects on the relationship between family-of-origin functioning and the fear of intimacy. That is, family-of-origin functioning was shown to have not only a direct effect, but also an indirect effect through attachment avoidance and attachment anxiety, on the fear of intimacy. The results of this study suggest that the importance of family-of-origin functioning in order to improve Korean college students' intimacy abilities.

  • 이 연구에서는 국내에 분포하는 화강암에 대한 점하중강도($I_{s(50)}$) 와 일축압축강도(UCS) 사이의 상관관계를 선형회귀분석을 통하여 구하였다. 이를 위하여 암석시료의 물리적 물성에 근거하여 화강암 시료를 재분류하여 세 경우에 대한 회귀분석을 수행하였다. 첫째로, 풍화등급에 따른 원점회귀분석을 수행하여 풍화에 따른 상관관계를 구하였으나 풍화등급별 시료의 개수가 부족하여 만족할만한 신뢰수준의 회귀분석결과를 얻지 못하였지만, 풍화가 진행될수록 회귀직선의 기울기가 급해지는 경향을 파악할 수 있었다. 두 번째, 전체 화강암에 대한 회귀분석을 수행하기 위하여 단순선형회귀분석과 신뢰도 및 정확도를 향상시키기 위하여 부트스트랩 리샘플링법을 이용한 단순선형회귀분석을 통하여 두 강도간의 상관관계를 구하였다. 세번째로는 유사한 물리적 물성을 지닌 화강암 시료들의 평균강도에 대한 선형회귀분석을 수행하여 상관관계를 구하였다. 이 방법들을 사용하여 구한 회귀직선방정식의 기울기는 14 내외의 값을 보이고 작은 편차를 지니고 있으며 국내 화강암에 대하여 수행한 기존 연구와 유사한 값을 보이고 있었다. 그러나 16에서 43의 범위를 지닌 y-축 절편은 큰 편차를 보이기 있었기 때문에, 점하중강도로 일축압축강도를 추정할 때에는 이러한 회귀방정식의 오차범위를 고려하여야 할 것으로 판단된다.

  • This study had the goal of investigating the effect of the curvature along the heating line on the transverse angular distortion of plates having an initial curvature from line heating. A thermo-elasto-plastic analysis was carried out using 54 models with various radii of curvature, plate thicknesses, and heating speeds. The results show the effect of the curvature along the heating line on the angular distortion in relation to changes in the magnitudes of the curvature, heating speed, and plate thickness. The present numerical results show that the time history of the angular distortion after cooling and reaching the final deformed shape for a plate having an initial curvature is quite different from that of a flat plate. This emphasized the importance of considering the curvature effect on the transverse angular distortion. From the viewpoint of the curvature effect on the deformation, it has been seen that the curvature does not affect the transverse shrinkage. In this study the predicting formula for the transverse angular distortion was derived through a regression analysis. It showed that as the curvature increased, the angular distortion was reduced because of the higher bending rigidity at the same heat input parameter, and the peak points moved toward the origin as the curvature increased.

  • Italian Ryegrass (IRG), which is known as high yielding and the highest quality winter annual forage crop, is grown in mid-south area in Korea. The objective of this study was to evaluate the use of unmanned aerial vehicle (UAV) for the monitoring IRG growth. Unmanned aerial vehicle imagery obtained from middle March to late May in Nonsan, Chungcheongnam-do. Unmanned aerial vehicle imagery corrected geometrically and atmospherically to calculate normalized difference vegetation index (NDVI). We analyzed the relationships between $NDVI_{UAV}$ of IRG and biophysical measurements such as plant height, fresh weight, and dry weight over an entire IRG growth period. The similar trend between $NDVI_{UAV}$ and growth parameters was shown. Correlation analysis between $NDVI_{UAV}$ and IRG growth parameters revealed that $NDVI_{UAV}$ was highly correlated with fresh weight (r=0.988), plant height (r=0.925), and dry weight (r=0.853). According to the relationship among growth parameters and $NDVI_{UAV}$, the temporal variation of $NDVI_{UAV}$ was significant to interpret IRG growth. Four different regression models, such as (1) Linear regression function, (2) Linear regression through the origin, (3) Power function, and (4) Logistic function were developed to evaluate the relationship between temporal $NDVI_{UAV}$ and measured IRG growth parameters. The power function provided higher accurate results to predict growth parameters than linear or logistic functions using coefficient of determination. The spatial distribution map of IRG growth was in strong agreement with the field measurements in terms of geographical variation and relative numerical values when $NDVI_{UAV}$ was applied to power function. From these results, $NDVI_{UAV}$ can be used as a new tool for monitoring IRG growth.

  • Object : The goals of this research were to make Performance Enhanced Model(PE) taken the largest performance index (PI) through artificial variation of principle components calculated by principle component analysis for trial data, and to verify the effect through comparing kinematic factors between trial data (Raw) and PE. Method : Ten subjects (5 men, 5 women) were recruited and 80% of their maximal record was considered. The PI is a regression equation. In order to develop PE, we extracted Principle components from trial position data (by Principle Components Analysis (PCA)). Before PCA, we made 17 position data to 3 row matrix according to components. We calculated 3 eigen value (principle components) through PCA. And except Y (medial-lateral direction) component (because motion of Y component is small), principle components of X (anterior-posterior direction) and Z (vertical direction) components were changed as following. Changed principle components = principle components + principle components ${\times}$ k. After changing the each principle component, we reconstructed position data using the changed principle components and calculated performance index (PI). A Paired t-test was used to compare Raw data and Performance Enhanced Model data. The level of statistical significance was set at $p{\leq}0.05$. Result : The PI was significantly increased about 12.9kg at PE ($101.92{\pm}6.25$) when compared to the Raw data ($91.29{\pm}7.10$). It means that performance can be increased by optimizing 3D positions. The difference of kinematic factors as follows : the movement distance of the bar from start to lock out was significantly larger (about 1cm) for PE, the width of anterior-posterior bar position in full phase was significantly wider (about 1.3cm) for PE and the horizontal displacement toward the weightlifter after beginning of descent from maximal height was significantly greater (about 0.4cm) for PE. Additionally, the minimum knee angle in the 2-pull phase was significantly smaller (approximately 2.7cm) for the PE compared to that of the Raw. PE was decided at proximal position from the Raw (origin point (0,0)) of PC variation). Conclusion : PI was decided at proximal position from the Raw (origin point (0,0)) of PC variation). This means that Performance Enhanced Model was decided by similar motion to the Raw without a great change. Therefore, weightlifters could be accept Performance Enhanced Model easily, comfortably and without large stress. The Performance Enhance Model can provide training direction for athletes to improve their weightlifting records.
