Molecular dynamics simulations have been performed to investigate the transport properties of self-diffusion coefficients in the penetrable-sphere model system. The resulting simulation data for the product of the packing fraction and the self-diffusion coefficient exhibit a transition from an increasing function of density in lower repulsive systems, where the soft-type collisions are dominant, to a decreasing function in higher repulsive systems, where most particle collisions are the hard-type reflections due to the low-penetrability effects. A modified Enskog-like equation implemented by the effective packing fraction with the mean-field energy correction is also proposed, and this heuristic approximation yields a reasonably good result even in systems of high densities and high repulsive energy barriers.

This study's research method was to investigate the effects of career development in the field of beauty on organizational commitment. A survey targeted 271 beauty workers living in Seoul and Gyeonggi-do. For data analysis, SPSS 21.0 was used for statistical processing. First, descriptive statistics were analyzed, followed by a factor analysis and reliability analysis, third, correlation analysis, and finally linear regression analysis. Detailed research results are as follows. First, the effect of career development of beauty workers and organizational commitment was investigated. The result is as follows. The independent variables, self-development, goal orientation, and career orientation, which are sub-variables of career development, were found to have a statistically significant positive effect. Second, the effect of career development of beauty workers on co-workers' organizational commitment was investigated. The result is as follows. By the independent variable, self-development, and career orientation, which are sub-variables of career development, are found to have a significant positive effect. However, goal orientation had no effect. Therefore, based on the results of this study, the implications are as follows. As beauty is a creative pursuit, it is often done in collaboration rather than alone, and therefore camaraderie plays an important part in the foundation of a commitment to a company. It is a field that goes after a goal after committing to a community mindset, instead of pursuing a goal alone.

Magnetic fields correlated on several kiloparsec scales are seen in spiral galaxies. Their origin could be due to the winding up of a primordial cosmological field or due to amplification of a small seed field by a turbulent galactic dynamo. Both options have difficulties: There is no known battery mechanism for producing the required primordial field. Equally the turbulent dynamo may self destruct before being able to produce the large scale field, due to excess generation of small scale power. The current status of these difficulties is discussed. The resolution could depend on the nature of the saturated field produced by the small scale dynamo. We argue that the small scale fields do not fill most of the volume of the fluid and instead concentrate into intermittent ropes, with their peak value of order equipartition fields, and radii much smaller than their lengths. In this case these fields neither drain significant energy from the turbulence nor convert eddy motion of the turbulence on the outer scale to wave like motion. This preserves the diffusive effects needed for the large scale dynamo operation.

Purpose: The purpose of this study was to identify the effects of the education program to promote self care for elderly patients with percutaneous coronary intervention. Method: The research was a quasi-experimental study using a nonequivalent control group non-synchronized design. The participants was 56 patients, 28 in the experimental group and 28 in the control group. A pretest and a posttest were conducted to measure main variables. The self care education program, consisting of flash animation, leaflet and telephone counseling, was given for the experimental group. Data were analyzed using ${\chi}^2$, Fisher's exact test, and independent t-test with SAS statistics program. Results: There were statistically significant increase in knowledge and self care behavior, and decrease in anxiety by difference between a pretest and a posttest in the experimental group compared to that in the control group. Conclusion: The result of this study indicate that the self care education program is effective in increasing knowledge and self care behavior, and in decreasing anxiety for elderly patients with percutaneous coronary intervention. Therefore, it can be usefully utilized in the field of nursing for elderly patients with percutaneous coronary intervention.

Yano method had been used in predicting the settlement of self-weight consolidation of dredged soil in the construction of reclamating the dredged soil. Its estimation was found to show some different results from field measurements. The numerical analysis with PSDDF was peformed find such differences, considering the effect of desiccation on the consolidation during the remaining time after reclamation. For the parametric study, numerical analyses with/without consideration of desiccation were carried out with changing the conditions of desiccation such as the number of placing the fill and the time period between each placement. As results of analysis, estimations about consolidation settlement and distribution of water contents with consideration of desiccation was in good agreements with field measurements. It was also found that the number of placing the fill and the time period between each placement did not affect the behavior of self-weight consolidation as much as the effect of desiccation.

This study analyzed the influences of child care accreditation system on the participants' successful experiences. Analysis of 20 protocols made by the participants showed three dimensions of effects (1) reinforcement of their speciality within the field of childcare, (2) psychological satisfaction; e.g. self-confidence and self-fulfillment, and (3) positive perspectives on child care accreditation. Conclusions were that child care accreditation is an effective system as long as it helps the participants achieve successful experiences. These data will be useful for understanding and publicity of the recently established child care accreditation system. Future research on this subject is needed not only to activate childcare study but also to contribute towards acceptance of the new system.

We investigated vertical liquid crystal (LC) alignment effects of a self-assembled-monolayer (SAM) prepared on an anisotropic $SiO_2$ surface where the field-induced LC reorientation produced a uniform single domain texture. We compared the results with the homeotropic-to-random planar reorientation results shown in LCs aligned on a SAM surface prepared on an isotropic $SiO_2$ surface.

In the United States, a marked emphasis on personal achievement has been among enduring values characterizing American culture from the beginning of the republic. Particularly, Americans have attached great value to the spirit of self-reliance in striving for personal achievement. However, there have been few empirical studies focusing on the effects of Americans' self-reliant spirit on American electoral politics. Through a field experimentation focusing on the voters of Portage County in Ohio, this study examined the effects of Americans' self-reliant spirit on the evaluations of presidential candidates' personal traits, which constitute the candidates' character. The results of this study demonstrated that American voters evaluated those presidential candidates who were described as self-reliant significantly more favorably than the presidential candidates who were not so described, for 8 out of the 11 personal traits. The findings provide meaningful evidence for ascertaining the potential and legitimacy of the influences of the spirit of self-reliance, in the American society including electoral politics.
