This study focuses on the workplaces of two distinct nations, the United States and Korea, to ascertain the impact of culture on emotional intelligence (EI). This paper examines if EI is dependant on culture by finding significant variances of emotional responses under a given situation. The results suggest that EI is significantly impacted by national culture. In addition, this study investigates the relationship between cultural distance and EI by using the secondary data of 19,402 participants across 13 nations. The results demonstrate that only power distance among Hofstede's dimensions has significant effect on EI.

Curvic coupling of mill turret should maintain disk weight and the cutting resistance which occurs the machining operation and must also have power transmission function. In order to improve machining operation range, the ejecting distance from curvic coupling to the disk must increase as much as possible. But moment is increased by the lack of capacity of the curvic coupling. Increase of moment is the cause of vibration/noise and degradation of machining performance not only stability problem. The manufacturer of mill turret has no the design information between the ejecting distance and the cutting resistance with safety of curvic coupling. Therefore this study describes a finite element analysis model of mill turret using ANSYS workbench. The structural analyses and modal analyses with varying of the ejecting distances and cutting resistances are performed. Finally the equation for relationship between the critical ejecting distance and the cutting resistance is defined under 5 of the safety factor for the maximum von-Mises stress at the curvic coupling.

Extreme ultraviolet (EUV) pellicle is one of the most concerned research in the field of EUV lithography (EUVL). Imaging performance of EUV mask with pellicle should be investigated prior to high volume manufacturing (HVM) of EUVL. In this paper, we analyzed the relationship between standoff distance and imaging performance of EUV mask to verify the influences of relative standoff distance on imaging performance. As a result, standoff distance of EUV pellicle has no effect on imaging performance of EUV mask such as critical dimension (CD), normalized image log slope (NILS) and image contrast. Therefore, pellicle support structure can be flexibly designed and modified in diverse ways to complement the thermal limitation of EUV pellicle membrane.

Recent advances in technology are evolving to enable individuals to perform various activities necessary for their lives, without being constrained by physical, temporal, and spatial constraints. The online services and experiences that originated from solving the discomfort in the actual offline space have created the newness that can only be experienced in the digital world and furthermore uniquely new experiences in actual space as well. While many previous studies have suggested several interpretations of unique individual behaviors in virtual environments, a recent research approaches virtuality as an interesting perspective of the change of thinking style. Virtuality is defined as how far apart we are from everyday reality, and if the individual faces a situation far from reality, the psychological distance of the individual becomes distant and ultimately leads to the thinking style of high construal level. Otherwise, it is said to have a relatively low construal level of thinking style. In this study, I try to confirm the virtual distance as the role of psychological distance in new virtual contexts. Simultaneously considering temporal distance, which are most used in psychological distance, and virtual distance based on virtuality, this study tries to find whether the effect of virtual distance on product attitude is the same as that of temporal distance and check the relationship between virtual distance and temporal distance in the context of consumers' product evaluations depending on product information type.

The anatomic structure around interproximal area plays an important role not only in the natural teeth, but also in the implant. The loss of papilla can lead to cosmetic deformity, phonetic problem, food impaction on the anterior dentition, and masticatory problem, food impaction and proximal caries on the posterior dentition. The purpose of this study was to evaluate the relationship between interdental papilla existence and distance from contact point to alveolar crest in Korean posteior dentition. 45 Korean adult patients(31males, 14 females) participated in this study. Measurements were carreid out total 126 interproximal areas, 18 first premolar, 31 second premolar, 40 first molar, and 37 second molar areas. Papilla index was recorded as suggested by Jemt. Distance between contact point and alveolar crest measrued by Florida $probe^{R}$, after flap elevation. Each distance was measured 10 times by every 0.1mm unit. The results showed that the mean Papilla index 1.37 and mean distance between contact point and alveolar crest was 7.44mm. The correlation between the Papilla index and distance was high negative correlation(Pearson correlation=-0.47), and it was statistically significant(P=0.000) When the distance between contact point and alveolar crest was 5mm, the loss of papilla was appeared almost in half cases. When the distance was 6mm, the papilla loss was present 95%, when 7mm, the papilla loss was 100%.

This study was to investigate the relationship between the distance and projection factors, angle factors of javelin in women's javelin throwing. The data were collected in the 2011 National Sports Festivals for 11 players. Three-Dimensional motion analysis using a system of 4 video cameras at a sampling frequency of 60 fields/s was performed for this study. The factors of release conditions calculated using Matlab 2009a program. The statical analysis on the records(n=42) included mean and standard deviation of the mean(SD), Pearson's product moment correlation coefficient(SPSS Version 16.0 for Windows). There was a statistically significant positive relationship between the records and release velocity(r=.866, p<.01), height(r=.433, p<.01) and height rate(r=.340, p<.05). The attitude angle, release angle, and attack angle showed not a statistically significant relationship between the records. The medial-lateral tilt angle of javelin showed not a statistically significant relationship between the records, but the yaw angle of javelin(r=.549, p<.01) showed a statistically significant positive relationship between the records.

This article presents a new family of the estimating functions related with minimum distance estimations, and discusses its relationship to the family of the minimum density power divergence estimating equations. Two representative minimum distance estimations; the minimum $L_2$ distance estimation and the minimum Hellinger distance estimation are studied in the light of the theory of estimating equations. Despite of the desirable properties of minimum distance estimations, they are not widely used by general researchers, because theories related with them are complex and are hard to be computationally implemented in real problems. Hopefully, this article would be a help for understanding the minimum distance estimations better.

Generally, to get the minimum distance between two arbitrary shapes that are composed of circular arcs and lines, we must calculate distances for all the possible pairs of the components from two given shapes. In this paper, we propose an efficient method for the minimum distance problem between two shapes by using their structural features after extracting the reduced component lists which are essential to calculate the minimum distance considering the relationship of shape location. Even though the reduced component lists may contain all the components of the shapes in the worst case, in the average we can reduce the required computation much by using the reduced component lists. This method may be efectively applied to calculating the minimum distance between two shapes which are generated by the CAD tool, like in the nesting system.

In this paper, we propose an error estimation method based on the Bhattacharyya distance for multimodal data. First, we try to find the empirical relationship between the classification error and the Bhattacharyya distance. Then, we investigate the possibility to derive the error estimation equation based on the Bhattacharyya distance for multimodal data. We assume that the distribution of multimodal data can be approximated as a mixture of several Gaussian distributions. Experimental results with remotely sensed data showed that there exist strong relationships between the Bhattacharyya distance and the classification error and that it is possible to predict the classification error using the Bhattacharyya distance for multimodal data.

Backgrounds: Cervical epidural nerve block is useful in the management of a variety of acute, chronic and cancer related pain syndromes involving the head, face, neck and upper extrimity. To safely perfom the cervical epidural block, an appreciation of the expected distance from skin to epidural space is important. We studied the distance from skin to cervical epidural space of adults to determine if any relationship exists between patient height, weight and neck circumference and the distance from skin to epidural space. Methods: Patients 170, suffering from neck and upper extremity pain with cervical HIVD(herniated intervertebral dics) were selected. Cervical epidural block was performed at $C_{6\sim7}$ or $C_{7-}T_1$ intervertebral space. Then measured the distance from skin to epidural space and analysed the relationship between age, height, weight and neck circumference and the distance from skin to epidural space. Results: The cervical epidural depth of male $C_{6\sim7}$, male $C_{7-}T_1$, female $C_{6\sim7}$ and female $C_{7-}T_1$ groups were $5.17{\pm}0.63$, $5.47{\pm}0.59$, $4.84{\pm}0.56$ and $5.01{\pm}0.60$ cm respectively. Cervical epidural depth significantly correlated with body weight, ponderal index and neck circumference. Conclusions: The distance from skin to cervical epidural space has significant relationships with weight, ponderal index and neck circumference. Although experience is important, patient's weight and neck circumference are indicating factor, of the cervical epidural depth.
