AIM To evaluate the accuracy of spherical equivalent (SE) estimates of a double-pass system and to compare it with retinoscopy, subjective refraction and a table-mounted autorefractor. METHODS Non-cycloplegic refraction was performed on 125 eyes of 65 healthy adults (age 23.5±3.0 years) from October 2010 to January 2011 using retinoscopy, subjective refraction, autorefraction (Auto kerato-ref...

AIM To evaluate the intra-operator repeatability in healthy subjects using the WAM-5500 auto-kerato/refractometer and the iTrace aberrometer, to compare the refractive values and the subjective refraction obtained with both devices and to determine which of these three spherocylindrical corrections allows the subject to achieve the best visual comfort. METHODS Forty-two non-presbyopic healthy...

Looking across many diseases, average health among mature men is much worse in America compared to England. Second, there exists a steep negative health gradient for men in both countries where men at the bottom of the economic hierarchy are in much worse health than those at the top. This health gradient exists whether education, income, or financial wealth is used as the marker of one's SES s...

Subjective tinnitus (ST) is a frequent but poorly understood medical condition. Recent studies demonstrated abnormalities in several types of eye movements (smooth pursuit, optokinetic nystagmus, fixation, and vergence) in ST patients. The present study investigates horizontal and vertical saccades in patients with tinnitus lateralized predominantly to the left or to the right side. Compared to...

When the probability of a single member of a set of mutually exclusive and exhaustive possibilities is judged, its alternatives are evaluated as a composite "residual" hypothesis. Support theory (Rottenstreich & Tversky, 1997; Tversky & Koehler, 1994) implies that the process of packing alternatives together in the residual reduces the perceived evidential support for the set of alternatives an...

There are two service selection strategies in dynamic service composition, i.e., global strategy and local strategy. The existed global service selection algorithms, due to insufficiently show users’ partiality and feature of the service, is unfavorable to encourage the service provider to optimize the service quality to some extent. In this paper, an ordinary utility function is used as a nume...

Job Insecurity and Youth Emancipation: A Theoretical Approach In this paper, we propose a theoretical model to study the effect of income insecurity of parents and offspring on the child’s residential choice. Parents are partially altruistic toward their children and will provide financial help to an independent child when her income is low relative to the parents’. We show that first-order sto...

[Purpose] The present study investigated what kind of effect smart phone use has on dynamic postural balance. [Subjects] The study subjects were 30 healthy students in their 20's who were recruited from a University in Busan, Korea. [Methods] The present experiment was quasi-experimental research which measured the postural balance (Biodex) of subjects while they sent text messages via smart ph...

In an effort to bolster soundness standards in banking, the 2006 international regulatory agreement of Basel II requires globally active banks to include operational risk in estimating regulatory and economic capital to be held against major types of risk. This paper discusses practical issues faced by a bank in designing and implementing an operational risk capital model. Focusing on the use o...

This paper acknowledges the role of entrepreneurship for the development of the process of sustained livelihood. The paper proposes a systematic usage of the ‘Capability’ approach (Sen, 2000) as the basis of the methodology applied by agencies having objectives in lieu with the process of sustained livelihood, because of the wider applicability and span of this approach. Taking examples of rura...
