We have evaluated the effects of experimental factors on transmitted electron beam intensities for quantitative analysis in electron tomography. For the correct application of Beer's law in electron tomography, the transmitted beam intensity should reflect the net effect of mass properties on beam path. So, the any other effects of the objective aperture and the specimen holder on beam path should be removed. The cut-off effects of objective aperture were examined using Quanti-foil holey carbon film and a transmission electron microscope operated at 120 kV. The transmitted beam intensities with $30{\mu}m$ objective aperture dropped about 16.7% compared to electron beam intensities without the objective aperture. Also, the additional losses of about 14.2% at high tilt angles were occurred by cut-off effects of the objective apertures. For the precise quantitative analysis in electron tomography, the effect of the objective aperture on transmitted electron beam intensities should be considered. It is desirable that 2-D tilt series images are obtained without the objective aperture for correct application of Bee's law.

Many game designers suggested that if players got many objective performance, they could have a fun experience while playing the MMORPG. Does a quantity of objective performance lead to player's fun experience in the MMORPG? According to the Equity Theory, the reason of players getting fun experience is not only that players get reasonable objective performances as many as efforts of theirs but also that amount of their objective performances were same as others. This study analysed that the equity of objective performances would have an effect on the player's fun experience. The results were that the equity of objective performances produced an effect on the players' behavioral intention, flow experience, and cognitive performance. Hence if game designers want that players are interested in the online game playing, they have to support the equity of objective performance to players.

Along with the well-established evidence on the negative effect of social isolation on physical mental health and mortality, increasing attention has been paid to multi-dimensional nature of social isolation. In this study, the main effect and interaction effect of objective and subjective social isolation on heterogeneous age cohort related to the onset of dementia, which is becoming a social problem due to rapid aging of health issues, was examined through binary logistic regression analysis. Data came from the first wave of Korean Social Life, Health and Aging Project (KSHAP) (N= 814). Findings showed 1) in the young-old, objective isolation was a significant on the incidence of dementia, 2) in the old-old, subjective isolation increased the risk of dementia. In summary, the relative influence of objective and subjective social isolation related to the incidence of dementia varies depending on the young-old and old-old. On the other hand, the interaction effect of objective and subjective social isolation on dementia was not significant in both the young-old and old-old. Based on the findings, we discussed implications and suggestions for future research and relevant policy and program development(dementia-friendly communities) for ameliorating objective and subjective social isolation.

This article presents a simple and reasonable in-service, real-time, and continuous single-ended objective video quality assessment model for DTV broadcasting using a multiburst signal at the bottom of the transient effect area, similar to Vertical Interval Test Signals. The issue of in-service video-quality monitoring in DTV broadcasting is addressed, and an effective method of quality monitoring is presented. The proposed method is also implemented and tested in a range of situations using a simulated HDTV broadcasting network.

By using finite ray-tracing and curve fitting, a numerical method to determine the non-paraxial pupil function of a high-NA objective is presented. MTF degradations caused by the non-paraxial diffraction effect are analyzed for on-axial imaging of a far-infrared objective and aberration-free ellipsoidal mirror system. The ellipsoidal mirror system has the same paraxial specifications as the far-infrared objective.

This study aims to understand the evaluation of importance, satisfaction and repurchase intention after dividing the attributes of environment-friendly fashion product in details. Out of 400 surveys, 328 were used in the final analysis of this study, with 113 respondents having experience of buying Environment-friendly fashion products. The analysis of this study is done by SPSS 18.0(ver.). Through the literature review, the objective attributes were subdivided into seven factors, including brand, environment-friendly materials, quality, environment-friendliness when using/managing, environment-friendliness when discarding, color/pattern, and environment-friendly design. Though an empirical study, the subjective attributes were subdivided into three factors, including innovation/individuality, practicality, and dignity/popularity. In the analysis results of the importance of the attributes of environment-friendly fashion products, it was shown that it was considered as importance as above average. The effect of the satisfaction of the objective attributes on the repurchase intention was measured. In the results, the regression model was significant while it was understood that the satisfaction of environment-friendly materials, environment-friendliness when discarding, color/pattern and environment-friendly design had positive effect on the repurchase intention. The effect of the satisfaction of the subjective attributes of environment-friendly fashion products on the repurchase intention was measured. In the results, dignity/popularity and innovation/individuality factors had positive effect on the repurchase intention.

Financial IT evaluation methods have been unable to satisfy firms' requirements. There has been a growing demand for more comprehensively and non-financially measuring the IT performance. We developed a process-based approach in evaluating impacts of IT on primary activities. In this research we proposed a model that uses the corporate objective of IT and strategic fitt as the core independent variables in measuring the IT effect. Based on the data collected from the management variables of the 125 companies located in Korea, the companies were classified into the 4 different groups according to their corporate objective for IT: un-oriented, operations oriented, market oriented and dual oriented. Through the empirical analysis, we were able to demonstrate that the management of the companies showing a higher orientation level perceives a better IT investment performance, and this shows that the corporate objective for IT serves as a useful index for measuring the IT investment effect. In this research, it was also demonstrated that the strategic alignment has a positive influence on perceiving the IT investment effect.

Objectives: The purpose of this study is to examine the process of how a parent-child relationship affects an impaired objective self, emotional regulation difficulties, and, consequently, interpersonal problems. Methods: To carry out this study, a total of 467 married women were surveyed on their parent-child relationship, impaired objective self, and emotional regulation difficulties. The resulting data was interpreted using descriptive statistics analysis, correlation analysis, and structural equation models analysis. Results: First, the parent-child relationship shows negative correlations with an impaired objective self, emotional regulation difficulties, and interpersonal problems. In addition, an impaired objective self, emotional regulation difficulties, and interpersonal problems show positive correlations with one another. Second, an impaired objective self and emotional regulation difficulties mediate the parent-child relationship and intrapersonal problems consecutively. Conclusions: This indicates that efforts to mitigate an impaired objective self and to intervene in difficulties in emotional regulation can help address intrapersonal difficulties. Finally, this paper examines how this study affects the ongoing discussion on this matter and its implications for future studies.

This article deals with the problem of testing whether the effect size in paired study exists. We propose Bayesian hypothesis testing procedures for the effect size in paired study under the noninformative prior. The noninformative prior is usually improper which yields a calibration problem that makes the Bayes factor to be defined up to a multiplicative constant. So we propose the objective Bayesian hypothesis testing procedures based on the fractional Bayes factor and the intrinsic Bayes factor under the reference prior. Simulation study and a real data example are provided.
