  • The purpose of this study was to investigate the influnce of afferent stimuli, transcutaneous electrical nerve stimulation and ultra sound, on the electrdiagnostic study of normal subjects. Electrodiagnostic study was performed before and after the application of afferent stimulation of the right popliteal fossa on 18 healthy female volunteers. After the transcutaneous electrical nerve stimulation, there is no significantly change of latencies and amplitudes of SEP, H-reflex, peroneal nerve F-wave, and sensory nerve conduction. After the ultra sound, there is no significantly change of latencies and amplitudes of SEP, H-reflex, peroneal nerve F-wave, and sensory nerve conduction. Tibial nope F-wave and motor nerve shows prolonged latency after TENS and US (p<0.01). Ultrasound may have a similar mechanism of action compared to transcutaneous electrical nerve stimulation by having localized inhibitory effects of the peripheral nerve. However, further investigation is needed to assess their mechanism of action and the precise relevance of stimulation modality.

  • The purpose of this study is to examine how change recipients react to change (affective commitment to change) and how change leads to positive consequences (job satisfaction) in Revolution and Evolution, taking into account the change content (perceived change impact), change context (change climate), and change process (participation in the change process). The present study uses a deductive approach with an exploratory research design. Data was collected from 254 employees of the head offices of three major banks, who have gone through Revolution, and 354 employees of the head offices, three banks who have gone through Evolution in the last five years. The hypothesized model is tested and analyzed through structural equation modeling using SmartPLS. The findings revealed that, in the case of Revolution, the presence of the favorable context and process might revert the negative perception of the change and lead towards explicit positive reactions (affective commitment to change) and change consequences (job satisfaction). In the case of Evolution, the change can be more effectively implemented using favorable context and process by achieving explicit positive reactions (affective commitment to change) and change consequences (job satisfaction).

  • The government has proposed a development model for universities to strengthen the capacity of the College of Humanities as part of the university restructuring policy in line with the trend of the times, and encouraged each university to voluntarily induce the establishment of the humanities development plan through financial support under their own individual conditions. With the decline in the school-age population due to the declining fertility rate, the rapid change in the industrial structure has highlighted the decline in the employment rate of the students of the humanities. Therefore, the government is implementing university grading based on the results of the university structural reform evaluation, and pressing low-grade universities through reduction of capacity and reduction of support. In the course of this change, universities have designated the College of Humanities as the primary target of integration with other majors or and its disintegration. This study examines the direction of the government's attempt to change the humanities in the era of the Fourth Industrial Revolution, and suggests a precedent example during the reform of the humanities college. If the humanities college is integrated with practical studies such as management, design, IT, CT, and engineering, the strengths of the humanities can be highlighted. However, the results of this study suggest that many variables such as consideration of students' aptitudes and interests in the integration process of majors, autonomy in major selection, understanding between departments integrated, and demand for a single major before integration or disintegration should be considered. In addition, an example of a local private university shows that the hasty attempt to integrate or disintegrate the humanities can rather lead to various educational harms.

  • Purpose: The purpose of this study was to investigate smoking cessation behavior of male taxi drivers in Korea on the basis of the Transtheoretical model(TTM), and to validate the usefulness of TTM. Method: Data were collected using a self-reported questionnaire including smoking history and major factors of TTM from 208 subjects who were current smokers or ex-smokers. Data were analyzed by descriptive statistics and ANOVA. Result: Most subjects ($85.1\%$) were current smokers. Stages of change were precontemplation ($44.7\%$) and contemplation ($27.4\%$). Subjects in precontemplation stages had the lowest mean score in processes of change and the highest mean scores in decisional balance(pros) and temptation(positive affective, habitual/craving). According to stages of change, there were statistically significant differences in processes of change, decisional balance, and temptation. Conclusion: This study supported the generalization of TTM. As this study showed that the subjects didn't have motivation in smoking cessation, applying tailored smoking cessation programs for taxi drivers is needed.

  • This experiment studied the change in a human's control of his or her static posture by analyzing the stabilogram diffusion and, by using the said study, evaluated the control ability of different groups with different experiences. The postures had a rising requirement of heel-rise according to three conditions: heel-toe, ball, toe; the groups were divided into dance major student and non-dance majors. The results of the critical points according to posture did not show a direct relation with the change in postures that had a rising requirement of heel-rise. The diffusion coefficient(D) had greater stochastic activity for short-term regions that utilize open-loop controls without feedback than for long-term regions that used closed-loop controls with feedback to maintain balance. The directional results of the body undergoing disturbance showed that A/P direction's diffusion coefficient (D) was larger than that of M/L direction. Both feet's planar diffusion coefficients were a linear combination of the diffusion coefficients calculated for the x and y axis. In studying the different abilities to control posture between a dance major student and a non-dance majors, a comparison of open-loop control's diffusion coefficient(D) was effective, and dance major student had superior control ability to that of non-dance majors.

  • Purpose. Despite many smoking cessation programs, many patients with CAD continue to smoke or re-smoke. The processes of change and self-change for smoking cessation is emphasized. The purpose of present study was to investigate decisional balances and processes of change according to stages of change for smoking cessation in the patients with CAD. Methods. This descriptive study was performed using the self-reported questionnaires from 157 male patients with CAD who have smoking experiences. The questionnaires consisted of decisional balances toward smoking (pros/cons) and processes of change including 7 factors. Results. 45.2% of the subjects had myocardial infarction and 54.8% for angina pectoris. Major stages of change were maintenance, contemplation, and precontemplation in 62%, 14%, and 18% respectively. The mean score of pros smoking was 31.07 and cons smoking was 32.52. The mean scores of processes of change were high in all 7 factors, especially in self determination. The pros smoking in precontemplation stage was significantly higher than those in other stages. Between contemplation and precontemplation stages, processes of change showed significant differences in stimulus control, self determination, information management, and dramatic relief. Conclusion. This study suggests that decisional balances and processes of change are stage-specific. As this study, smoking cessation program in the patients with CAD must put priority on the patients group in pre-contemplation and contemplation stages, and stress self determination and dramatic relief.
