Abstract: The purpose of this study is to investigate the psychometric properties and factor structure of a popular second language reading motivation questionnaire developed by Mori (2002). 550 first year high school students in Korea answered the 30-item questionnaire which consists of statements indicating different degrees of English reading motivation. Exploratory factor analysis was conducted with principal axis factoring and promax rotation, which yielded a four-factor solution. The factors included ‘Intercultural and Intellectual Orientation’, ‘Reading Efficacy’, ‘Intrinsic Motivation’, and ‘Negative Attitudes’. The results supported the multidimensionality of the construct of L2 reading motivation, but could not replicate the nine factor structure …which was originally proposed by Mori. The implications for further research on L2 reading motivation and development of a more valid L2 reading scale are discussed. Show more

Abstract: Recently, the interest toward human longevity free from diseases is being converged as one system frame along with the development of mobile computing environment, diversification of remote medical system and aging society. Such converged system enables implementation of a bioinformatics system created as various supplementary information services by sensing and gathering health conditions and various bio-information of mobile users to set up medical information. The existing bio-information system performs static and identical process without changes after the bio-information process defined at the initial system configuration executes the system. However, such static process indicates ineffective execution in the application of mobile …bio-information system performing mobile computing. Especially, an inconvenient duty of having to perform initialization of new definition and execution is accompanied during the process configuration of bio-information system and change of method. This study proposes a dynamic process design and execution method to overcome such ineffective process. Show more

Abstract: The application of transcutaneous electrical nerve stimulation (TENS) enhances muscle weakness and static balance by muscle fatigue. It was said that TENS affects decrease of the postural sway. On the other hand, the applications of TENS to separate dorsi-plantar flexor and the comparison with and without visual input have not been studied. Thus, the aim of this study was to compare the effects of TENS on fatigued dorsi-plantar flexor with and without visual input. 13 healthy adult males and 12 females were recruited and agreed to participate as the subject (mean age 20.5 ± 1.4, total 25) in this study …after a preliminary research. This experiment was a single group repeated measurements design in three days. The first day, after exercise-induced fatigue, the standing position was maintained for 30 minutes and then the postural sway was measured on eyes open(EO) and eyes closed(EC). The second, TENS was applied to dorsi flexor in standing position for 30 minutes after conducting exercise-induced fatigue. On the last day, plantar flexor applied by TENS was measured to the postural sway on EO and EC after same exercise-induced fatigue. The visual input was not statistically difference between the groups. However, when compared of dorsi-plantar flexor after applied to TENS without visual input, the postural sway of plantar flexor was lower than the dorsi flexor (p < 0.05). As the result, the application of TENS in GCM clinically decreases the postural sway with visual input it helps to stable posture control and prevent to falling down. Show more

Abstract: This suggests indicators to be considered in the protocol for setting up equipment and minimizing patient doses by identifying the effective dose and correlations of each equipment company according to a patient's body characteristics in liver CT. The study was conducted with 445 patients who went to the hospital and received liver CT at the diagnostic radiology department of S medical center from 2010 January to June. As the statistical methods, t-test, one-way ANOVA, and Pearson's correlation analysis were used. The study results show that as height, weight, and BMI increased, the effective dose increased with all equipment vendors. Correlations …between a patient's body characteristics and the effective dose were shown to be positive with all equipment vendors in regard to weight, BMI, and height, in order. Show more

Abstract: The photoplethysmogram (PPG) is an extremely useful medical diagnostic tool. However, PPG signals are highly susceptible to motion artifacts. In this paper, we propose a cyclic moving average filter that use similarity of Photoplethysmogram. This filtering method has the average value of each samples through separating the cycle of PPG signal. If there are some motion artifacts in continuous PPG signal, disjoin the signal based on cycle. And then, we made these signals to have same cycle by coordinating the number of sample. After arrange these cycles in 2 dimension, we put the average value of each samples from starting …till now. So, we can eliminate the motion artifacts without damaged PPG signal. Show more

Abstract: Background: It has been previously demonstrated that listening to 1/f sound effectively reduces stress. However, these findings have been inconsistent and further study on the relationship between 1/f sound and the stress response is consequently necessary. Objective: The present study examined whether sound with 1/f properties (1/f sound) affects stress-induced electroencephalogram (EEG) changes. Methods: Twenty-six subjects who voluntarily participated in the study were randomly assigned to the experimental or control group. Data from four participants were excluded because of EEG artifacts. A mental arithmetic task was used as a stressor. Participants in the experiment …group listened to 1/f sound for 5 minutes and 33 seconds, while participants in the control group sat quietly for the same duration. EEG recordings were obtained at various points throughout the experiment. After the experiment, participants completed a questionnaire on the affective impact of the 1/f sound. Results: The results indicated that the mental arithmetic task effectively induced a stress response measurable by EEG. Relative theta power at all electrode sites was significantly lower than baseline in both the control and experimental group. Relative alpha power was significantly lower, and relative beta power was significantly higher in the T3 and T4 areas. Secondly, 1/f sound and simple resting affected task-associated EEG changes in a similar manner. Finally, participants reported in the questionnaire that they experienced a positive feeling in response to the 1/f sound. Conclusions: Our results suggest that a commercialized 1/f sound product is not more effective than simple resting in alleviating the physiological stress response. Show more

Abstract: This study aimed to evaluate the relative speed (RS) of latent images in relation to changes in the fading time and storage temperature of imaging plates (IPs) in computed radiography systems. The storage temperatures adopted were 20, 30, and 40°C, while the fading times employed were 0, 4, 8, 12, and 24 hours. The X-ray exposure factors were 50 kVp, 10 mAs, and a 150 cm distance from an IP to an X-ray source. In the processing of each image, the parameters used for multi-scale image contrast amplification were multiscale image contrast, noise reduction, edge enhancement, and latitude reduction, all …assigned a value of 0. Image sensitivity was used to convert linear properties. The RS used for the characteristic curve was evaluated using a uniform aluminum 11-step wedge. Results show that the RS values of IPs with changing fading time were 17.8 ± 0.9 at 20°C, 13.9 ± 1.1 at 30°C, and 13.4 ± 0.9 at 40°C. On the basis of these findings, we conclude that IPs should be stored in the long term at temperatures as low as 20°C. Show more

Abstract: The narrative structure of The Story of Sim Cheong exists on two levels: the narrative structure of the surface and the narrative structure of the unconscious ness in my terminology. The former is deduced from the content of the work corresponding to the concept of objective physical reality, and the other to the concept of psychic reality according to Freud. I see that the heroine Cheong was in an incestuous love relationship with her blind father nicknamed Sim Bongsa – Sim being his family name, Bongsa meaning the blind person – at the unconscious level. Their relationship became an incestuous …symbiosis in which they are indispensable to each other. However, there is a break-up of their intimate relationship between father and daughter due to her abandonment by her father. This abandonment results in turn by her abandoning him; there is a mutual abandonment between the father and the daughter. A psychoanalytic study leads us to discover the narrative structure of the unconsciousness of The Story of Sim Cheong: being abandoned by her father and abandoning him from the perspective of the daughter.
