The objective of this study was to investigate the influence of adding Gastrodiae rhizoma powder on quality attributes of sponge cake. The cake was made with various Gastrodiae rhizoma powder concentration(0.5%, 1%, and 1.5%) added, and it was stored for 5 days at three different temperatures(5, 15, and $25^{\circ}C$). By analyzing the mixogram data of wheat flour-Gastrodiae rhizoma powder composite flour, the ascending angle of the samples containing Gastrodiae rhizoma powder was increased and the descending angle had upper values compared with that of control as the Gastrodiae rhizoma powder addition concentration was increased. The loaf volume of 0.5% Gastrodiae rhizoma powder slightly increased by 5.1% but those of 1% and 1.5% were slightly decreased compared with that of the control. Crumb firmness of the control showed relatively high value compared with those($5{\sim}6\;N$) of other samples containing Gastrodiae rhizoma powder regardless of storage temperature and storage period, and the firmness after 5 day storage at $5^{\circ}C$ showed the highest value(about 9.3 N). Sensory evaluation attributes of sponge cakes did not show significant difference by Gastrodiae rhizoma powder addition up to concentration of 1.5%.

The speed variation of SRM is fulfilled throughout a transition from chopping control to single pulse operation. (i,e., low speed to high speed operation). It is unsatisfied with performance at all operational regimes. In this paper, the operational performance of SRM can be improved by using current hysteresis control method. This method maintains a generally flat current waveform. At the high speed, the current chopping capability is lost due to the development of the back-EMF. Therefore SRM operates in single pulse mode. By using zero-current switching and zero-voltage switching technique, the stress of power switches can be reduce in chopping mode. When the commutation from one phase winding to another phase winding, the current can be zero as fast as possible in this period because several times negative voltage of DC-source voltage produce in phase winding. This paper is compared to performance based on conventional C-dump converter topology and the proposed resonant C-dump converter topology. Simulation and experimental results are presented to verify the effectiveness of the proposed circuit.

Effect of blanching and/or $CaCl_2$ addition on the quality characteristics of Oiji prepared by dry salting method, which has been used for industry, was investigated. Control$(15\%\;salt),\;CAO(15\%\;salt\;+\;0.04\%\;CaCl_2)$ and BCO $(15\%\;salt\;+\;0.04\%\;CaCl_2+blanching\;at\;60^{\circ}C\;for\;20\;min)$ for 165 days. Acidity was lower, but pH was higher in BCO than in the control or CAO. During the whole period of storage, greenness(-a) of BCO was maintained in Hunter color system, compared with the other groups. The numbers of total microbes, lactic acid bacteria and yeast were the lowest in BCO, while the highest in control. Moreover, texture profile analysis exhibited that fracturability and hardness maintained the highest in BCO during storage, compared with the other groups. Based on these results, combination of blanching and $CaCl_2$ addition is favorable to extend the shelf life and to maintain the good quality.

In this paper, the implementation of a production control system based on RFID has been studied in order to obtain an exact Cost Center data such as the name of workers included a process of work and a time period to finish the process. The cost center of a worker will be correctly obtained by checking the work time using RFID tag data and by transmitting the data to a server of ERP or POP system. And also warming up time, cleaning time, power failure, and out of order sign will be checked and calculated using the data stored in RFID tags attached in workers and machine facilities. Therefore, exact Cost Center data will be obtained by the production control system with touch screens entering the data according to the situation in real time.

Purpose: This study was conducted to examine the effects of a multicultural course on nursing students' multicultural acceptability and competency. Method: The research design for this study was a non-equivalent control group, non-synchronized pre- and post-test. The experimental group (n=28) took 13 weeks of the multicultural course, while the control group (n=28) received only regular classes over the same period. Pre- and post-tests were done to identify the effects of the program. The data were collected using self-administered questionnaires and analyzed using the PASW 18.0 program. Results: All indices of multicultural acceptability and competency in the experimental group were significantly higher than that of control group after the program, except for two: universality (a measure of multicultural acceptability) and multicultural awareness (a measure of multicultural competency). Conclusion: These results suggest that the multicultural course was effective in elevating the level of multicultural acceptability and competency among nursing students.

In the attitude and orbit control subsystem design, the moment of inertia of the satellite is the major contributor to be considered. Satellites equipped with large solar arrays need to measure the moment of inertia accurately to avoid the interference of the thruster actuation period with its flexible mode. In this paper, the in-orbit tests of COMS to measure the moment of inertia are described. Then, the differences between the measured through in-orbit test and the predicted are compared. Finally, it is verified that the differences are below uncertainty bounds considered in the critical design of COMS attitude and orbit control subsystem.

The aim of the present study was to examine whether repetitive transcranial magnetic stimulation (rTMS) can improve gait ability of acute stage stroke patients. This study was conducted with 39 subjects who were diagnosed as having a hemiparesis due to stroke. The experimental group included 20 subjects who underwent repetitive transcranial magnetic stimulation and the control group included 19 subjects who underwent sham therapy. The stroke patients in the experimental group underwent conventional rehabilitation therapy and rTMS was applied daily to the hotspot of the lesional hemisphere. The stroke patients in the control group underwent sham rTMS and conventional rehabilitation therapy. Participants in both groups received therapy five days per week for four weeks. Temporospatial gait characteristics, such as stance phase, swing phase, step length in affected side, velocity, and cadence, were assessed before and after the four week therapy period. A significant difference was observed in post-treatment gains for the step length in the affected side, velocity, and cadence between the experimental group and control group ( p < 0.05). However, no significant differences were observed between the two groups on stance phase and swing phase ( p > 0.05). We conclude that rTMS may be beneficial in improving the effects of acute stage stroke on gait ability.

Subacute toxicities of DWH-Ol(Ranitidine : Bismuth : Sucralfate=1.5:2:6) were inverstigated in Sprague-Dawley rats. After oral administration of DWH-01 with different dosages of 5 g/kg, l g/kg, and 0.2 g/kg, we examined the number of deaths, general signs, food intake, water intake, body weight and histopatholgical changes for both sexes of rats. During the adminstration period, urinalysis and opthalmological examination were also performed in the treated animals. 1) Animals were all survived for 4 weeks. 2) There were no significant differences in pathological and opthalmological findings between the control and treated animals. 3) There were no significant changes in body weight, food intake and water intake compared with control group. 4) In hematological examination and blood chemical analysis, there was no significant change compared with control group. 5) In histopathological examinations of organs and tissues, there was some hemorrhage in a lung tissue of low dose group, but it was thought to be caused by environmental factor. These data suggest that DWH-01 is not subacutely toxic in Sprague-Dawley rats.

Objective: The objective of this study is to investigate the effect of treadmill gait trainig on dynamic balance and gait functions in stroke patients. Design: Randomized, double-blind, controlled pilot study. Methods: Four subjects following first stroke participated in this study. They were divided randomly into the treadmill gait trainig group (TM group) (n=2) and the control group (n=2). Subjects in both groups received general training five times per week. Subjects in the TM group practiced an additional treadmill gait trainig program that consisted of 60 minutes, three times per week, during a period of four weeks. Timed up and go test (dynamic balance) and the GAITRite test (gait function) were evaluated before and after the intervention. Results: In dynamic balance (timed up and go test), the TM group (-14.235 sec) showed a greater decrease than the control group (-13.585 sec). In gait functions, the TM group showed a greater increase in gait speed (12.8 cm/s vs. 10.15 cm/s), step-length (5.825 cm vs. 3.735 cm), and stride-length (5.005 cm vs. 1.55 cm) than the control group. Conclusions: The treadmill gait trainig improved dynamic balance and gait functions. Further research is needed in order to confirm the generalization of these findings and to identify which stroke patients might benefit from treadmill gait trainig.

Purpose: The purpose of this study was to identify the effects of a smoking cessation program on processes of change, situational temptation, and decisional balance in male university student smokers. Method: Utilizing a quasi-experimental design, 78 male university students consisted of an experimental group (n=48) and a control group (n=30). A smoking cessation program was applied to the experimental group for a period of 6 months while no program was given to the control group. Study questionnaires were used to measure outcome variables before and after the program. Descriptive analysis, $\chi^2$-test, t-test, and ANCOVA were used with SPSS 18.0 program for data analysis. Results: After treatment with this program, the experimental group showed significantly higher scores for processes of change (experiential and behavioral processes of change) than the control group. The experimental group also showed significantly lower scores for situational temptation (positive social, negative affect, and habit strength). Conclusion: The smoking cessation program may have positive effects on process of change and smoking temptation for male university student smokers.
