The purpose of the study was to identify dimensions of benefit sought where consumer cross-border online shoppers seek and to examine the effects of the dimensions on expectancy, perceived performance, disconformity and satisfaction with cross-border online shopping. A total of 258 data were gathered and analyzed using SPSS 22.0. The results of the study identified that six dimensions of benefit sought of cross-border online shopping, which were economic-efficiency, convenience, uniqueness, scarcity, superiority and conformity seeking. There were significant effects of economic-efficiency, scarcity and uniqueness seeking on the expectancy, perceived performance, and satisfaction. In addition, consumers were segmented as four clusters classified using benefit sought of cross-border online shopping. The four clusters were labeled as "high interest type", "disinterested type", "unique scarcity type", and "price-first unfussy type". The significant differences were found among the clusters in the research constructs of expectancy and disconfirmation theory. The findings of the study suggested practical and managerial implications.

In the context of export-oriented growth strategy, Korea has promoted the conclusion of FTAs and 16 FTAs have entered into force or concluded so far. Despite of these efforts, the expansion of the global value chain (GVC) has resulted in fragmentation of production processes and international companies have been struggling to meet the criteria for determining the rule of origin. In order to overcome these difficulties, some foreign FTAs have been introducing cross-cumulation of origin. In this paper, we try to examine empirically whether the easing of the rules of origin using cross-cumulation contributes to the increase in actual value-added exports. we quantify the effects of cross-cumulation included in the EU-Vietnam FTA on Korean exports of the textile through a gravity model using the concept of value-added export. Based on the analysis results, the proportion of value-added exports in Vietnam increased by adoption of cross-cumulation of origin, which consequently resulted into an increase in total exports. This paper tries to draw several implications for the rules of origin in Korea's FTAs including cross-cumulation considering the export value chain of Korea.

The linear motors are easily affected by load disturbance, force ripple, friction, and parameter variations because there is no mechanical transmission to reduce the effects of model uncertainties and external disturbance. For highspeed/high-accuracy position control of a linear-motor-driven two axes, a nonlinear adaptive controller including a cross-coupling algorithm is designed in this paper. The nonlinear effects such as friction and force ripple are estimated and compensated. An enhanced approach for cross-coupling algorithm is proposed to effectively improve the biaxial contour accuracy with the closed-loop stability. The proposed controller is evaluated through the computer simulations.

Common belief in border regions holds that Mexican cross-border shoppers play a larger role in the regional economic base than they do and that NAFTA will provide a bigger stimulus to the regional economy than it is likely. In the regional economy than it is likely. In the first case, price elasticities are implicitly underestimated as highly inelastic and in the latter case, overestimated as highly elastic. This paper provides empirical evidence on the effects of distance and real exchange rates as price proxies on both field survey and population-imputed estimates of cross-border shopping. After estimating both distance-based and real exchange rate-based estimates of price elasticities of Mexican shopper demand for U.S. border-region goods, implications are obtained concerning the relative importance for U.S. border-regon economies of more distant Mexican markets, and the likely impacts of NAFTA.

In this article, we report a new empirical formula for quick calculation of cross sections of (n, α) reactions with 14-15 MeV neutrons. Cross sections are analysed in terms of the compound nucleus model. A systematic trend for 14-15 MeV neutrons is found in the variation of (n, α) reaction cross sections with the parameters (N - Z + 1), (E_n + Q)^0.5 and N/Z. The empirical relation between the cross sections and these parameters has been obtained, which give fairly good fits with the experimental data. We have also investigated the odd-even effects on (n, α) cross sections considering binding energy systematic of the shell model. The present formula is very useful in predicting of the (n, α) cross sections, where the measurements are not available as well as in testing new experimental data.

Purpose: The purpose of this study was to determine the effects on improvement of the range of motion in the TM joint. Methods: 26 subjects who have TM joint limitation were divided to passive movement group(n=13, $21.3{\pm}2.95$ years) and active movement group(n=13, $20.62{\pm}1.39$ years). All of the subjects were treated 5 to 10 minutes per one time, five times once a week for 4 weeks by the physical therapist. The open bite and cross bite were investigated at before, during(2 wks) and treatment(4 wks). Results: In order to assure the statistical significance of the result, a Repeated measures ANOVA were applied at the 0.05 level of the significance. There was a significant difference in terms of the rates of open bite mean change in within-open bite effects among pre-test, post-test 2weeks and post-test 4weeks in each group(P=0.029). There was no significant difference in the rates of mean change in between-open bite effects(P=0.441) but interactions between two types of effects(P=0.025) were statistical significance among pre-test, post-test 2 weeks and post-test 4 weeks in each group. There was no significant difference in the rates of mean change in within-close bite effects(P=0.112), between-cross bite(P=0.179) and interactions between the two types of effects(P=0.098) among pre-test, post-test 2 weeks and post-test 4 weeks in each group. Conclusion: The results of this study showed that passive movement and active movement were effect on increase of TM joint ROM about open bite and cross bite.

In this paper, we present a cross-layer analysis of wireless TCP systems over correlated channels. The effects of error correlation on the behavior of link retransmission strategy and the end-to-end throughput of TCP layer are investigated. Based on the cross-layer analysis, an efficient refinement of link layer protocol is proposed by consciously utilizing the information of channel correlations, which leads to the performance improvement of wireless TCP systems.

Electroconvulsive therapy(ECT) is one of the most effective treatment modalities for the treatment of depression, mania, schizophrenia, or other neuropsychiatric disorders. But, reportedly ECT also can produce various forms of cardiac arrhythmia. We experienced a case of ECT-induced arrhythmia(PVC) accompanied with chest pain in a schizophrenic patient during the course of plain ECT. We conclude that there is a possible causal relationship between ECT and cardiac arrhythmia(PVC). The mechanisms of cardiac arrhythmia(PVC) due to ECT may be explained by the effects of ECT to vagal and sympathetic nervous systems. from this case report, We suggest that careful cardiac monitoring before, during, and after ECT with appropriate anesthetic preparation to a patient may enable to minimize the cardiovascular side effects of ECT in the patients with neuropsychiatric disorders.

The looper of a hot strip finishing mill is installed between each pair of stands and plays a key role to enhance the product quality of strip by controlling the tension and height of strip in each inter-stand. Though the conventional looper control has achieved the mass products of strip so far, it has difficulties not only tuning gains by means of errors which are caused by coupling effects between strip tension and looper angle both utilizing tension feedback. Therefore, the non-interactive control employing cross controller and tension feedback has been introduced in looper control system in order to overcome the coupling effects existing between tension and looper angle and track the reference tension efficiently. In this paper, we present the cross controllers which play a role to decouple reciprocal effects between tension and looper angle and show better performance.

Wind tunnel aeroelastic model tests of the Commonwealth Advisory Aeronautical Research Council (CAARC) standard tall building were conducted using a three-degree-of-freedom base hinged aeroelastic(BHA) model. Experimental investigation into the effects of coupled translational-torsional motion, cross-wind/torsional frequency ratio and eccentricity between centre of mass and centre of stiffness on the wind-induced response characteristics and wind excitation mechanisms was carried out. The wind tunnel test results highlight the significant effects of coupled translational-torsional motion, and eccentricity between centre of mass and centre of stiffness, on both the normalised along-wind and cross-wind acceleration responses for reduced wind velocities ranging from 4 to 20. Coupled translational-torsional motion and eccentricity between centre of mass and centre of stiffness also have significant impacts on the amplitude-dependent effect caused by the vortex resonant process, and the transfer of vibrational energy between the along-wind and cross-wind directions. These resulted in either an increase or decrease of each response component, in particular at reduced wind velocities close to a critical value of 10. In addition, the contribution of vibrational energy from the torsional motion to the cross-wind response of the building model can be greatly amplified by the effect of resonance between the vortex shedding frequency and the torsional natural frequency of the building model.
