The purpose of this study was to examine physical properties of the addition of Plantago powder on bread flour and dough fheology of white pan bread. Four levels(0.3, 0.6, 0.9 and 1.2%) of each Plantago powder with bread flour were tested for their effects in dough mixing using rapid visco analyzer, alveogram, farinogram and sensory test. Addition of Plantago powder(0.3, 0.6 and 0.9% ) showed almost same tendency on the initial pasting temperature but 1.2% increased it. Increment of Plantago powder showed increment of peak viscosity and final viscosity, L(extensibility) and G(swelling index) value in alveogram showed decrement with increasing Plantago powder. In farinogram the use of Plantago powder increased consistency and water absorption but decreased development time and stability. White pan bread using Plantago powder had higher value of Max. G and gardeness in rheometer than without using it. Sensory evaluation of white pan bread with 0.6% Plantago powder had the highest score.

Two experiments were conducted to examine whether the word superiority effect (WSE) can be affected by visual familiarity of Hangout font and visual identicalness between target letter and test letter. In experiment 1, Using Batang-font as a target font, it was tested whether the consistency between test font and target font could affect the WSE across different display time conditions. In experiment 2, using the Batang-font and Sebeul-font, the effort of visual familiarity on WSE were investigated. The results revealed that the WSE was found regardless the consistency between target and test letter. In addition, it was found that visual familiarity could affect overall detection rate, but not WSE. These results suggested that the WSE on Hanguel is independent of visual properties.

Many researches are going on with regard to issues and problems related to mobile database systems, which are caused by the weak connectivity of wireless networks, the mobility and the portability of mobile clients. Mobile computing satisfies user's demands for convenience and performance to use information at any time and in any place, but it has many problems to be solved in the aspect of data management. The purpose of our study is to design Mobile Continuous Query Processing System(MCQPS) to solve problems related to database hoarding, the maintenance of shared data consistency and the optimization of logging, which are caused by the weak connectivity and disconnection of wireless networks inherent in mobile database systems under mobile client server environments. We proved the superiority of the proposed MCQPS by comparing its performance to the C I S(Client-Intercept-Slaver) model. In Addition, we experiment on proposed index structure and methodology in various methods.

Purpose: Accuracy and variability of movement in daily life require synchronization of muscular activities through a specific chronological order of motor performance, which is controlled by higher neural substrates and/or lower motor centers. We attempted to investigate whether transcranial direct current stimulation (tDCS) over primary sensorimotor areas (SM1) could influence movement variability in healthy subjects, using a tapping task. Methods: Twenty six right-handed healthy subjects with no neurological or psychiatric disorders participated in this study. They were randomly and equally assigned to the real tDCS group or sham control group. Direct current with intensity of 1 mA was delivered over their right SM1 for 15 minutes. For estimation of movement variability before and after tDCS, tapping task was measured, and variability was calculated as standard deviation of the inter-tap interval (SD-ITI). Results: At the baseline test, there was no significant difference in SD-ITI between the two groups. In two-way ANOVA with repeated measurement no significant differences were found in a large main effect of group and interaction effect between two main factors (i.e., group factor and time factor (pre-post test)). However, significant findings were observed in a large main effect of the pre-post test. Conclusion: Our findings showed that the anodal tDCS over SM1 for 15 minutes with intensity of 1 mA could enhance consistency of motor execution in a repetitive-simple tapping task. We suggest that tDCS has potential as an adjuvant brain facilitator for improving rhythm and consistency of movement in healthy individuals.

Background: Measuring effects of cancer on family caregivers is important to develop methods which can improve their quality of life (QOL). Nevertheless, up to now, only a few tools have been developed to be used in this group. Among those, the Caregiver Quality of Life Index-Cancer Scale (CQOLC) has met minimum psychometric criteria in different populations in spite of conflicting results. The present study was conducted to evaluate reliability and validity of CQOLC among Turkish cancer family caregivers. Materials and Methods: The CQOLC was administered to 120 caregivers, along with Beck Depression Inventory (BDI), Medical Outcomes Study MOS 36- Item Short Form Health Survey (SF-36), State-Trait Anxiety Inventory (STAI), and Multidimensional Scale of Perceived Social Support (MSPSS). Internal consistency and test-retest stability were used to investigate reliability. Construct validity was examined by using known group method, convergent, and divergent validity. For the known group method, we hypothesized that CQOLC scores would differ between depressed and non-depressed subjects. We investigated convergent validity by correlating scores for CQOLC with scores for other similar measures including SF-36 and STAI. The MSPSS was completed at the same time as CQOLC to provide divergent validity. Results: The values for internal consistency and test-retest correlation were 0.88 and 0.96, respectively. The CQOLC discriminated those who were depressed from those who were not. Convergent validity supported strong correlations between CQOLC scores and two main component scores (PCS, MCS) in SF-36 although there was a weak correlation between CQOLC and STAI scores. Regarding divergent validity, the correlation between CQOLC and MSPSS was in the low range, as expected. Conclusions: The Turkish CQOLC is a reliable and valid tool and it can be utilized to determine QOL of family caregivers.

Based on the importance of asset allocation in the return of an investment portfolio, this article attempts to verify the appropriateness of mutual funds as means of investment to obtain optimal asset allocation. The return-based style analysis is applied to determine a mutual fund's allocation(or a style) among a set of specified asset classes. Assuming a particular investor who defines a range allowed a fund's style to differ from its original one, it is examined whether or not the fund style is continued over an investment time horizon. After verifying the fact that the original style of the investment fails to remain unchanged from the empirical analysis limited to domestic equity mutual funds, we further investigated the reasons for the style drift. Despite several limitations of the analysis, it yields the conclusion that domestic equity mutual funds do not seem to be an appropriate investment tool to achieve a target asset allocation.

The rheological studies on dilute and concentrate solutions of naked and covered barley starches were carried out with various viscosimeters. The rheology of dilute solutions (0.05-0.3%) were characterized by intrinsic viscosity and related parameter according to Huggins equation. Also, the rheology of the solutions of higher concentrations (1-5%) were characterized by time dependent characteristics and pseudoplastic behaviors. The values of consistency index according to the power equation were exponen tially dependent upon concentration and temperature. The results showed that the rheological properties could differ greatly due to difference in varieties. The naked barley starch exhibited higher intrinsic viscosity, more thixotropic behavior and more dependence of consistency index on concentration and temperature than the covered barley starch.
