This present study is designed to analyze the mortality and potential years of life lost (PYLL) by malignant neoplasm of lung between OECD countries and Korea before and after the year 2000. We used the methods of Wilcoxon Singed Ranks Test between korean and other 30 OECD countries between 1993-1999 and 2000-2006 year using 2009 OECD Health data(2010) of 30 contries. At the results, the mortality of lung cancer in male korean was significantly increased after 2000 year whereas those in other 23 countries decreased. The mortalities in female were increased in 20 countries including Korea. PYLL in male and female korean were significantly decreased and male PYLL in other 26 countries was decreased, but female PYLL in other countries showed various patterns; increase in 12 countries and decrease in 3 countries. Therefore, the present study elucidated that the lung cancer-induced PYLL in the comparison between korean and OECD countries can be more important parameter.

Objective : The purpose of this study was to investigate the effects of virtual reality-based activities of daily living (ADL) training on ADL and rehabilitative motivation in patients with traumatic brain injury. Methods : This study was performed using a pre-post design with seven traumatically brain injured patients. Subjects were subjected to virtual reality-based ADL training for 30 minutes a day, 2 to 3 times a week for 4 weeks. Evaluation was conducted before and after the intervention using the Korean Modified Barthel Index (K-MBI), Cognitive Functional Independence Measure (C-FIM), and Volitional Questionnaire (VQ). Changes before and after intervention were analyzed by Wilcoxon signed-rank test, and correlations were analyzed using Spearman's coefficient. Results : After intervention, patients with traumatic brain injury showed significant improvements in K-MBI (p<.05). There was no significant change in total C-FIM score and VQ score (p>.05). Total C-FIM score correlated significantly with VQ score (p<.05, r=.755). The social cognition domain of C-FIM had a significant correlation with VQ score (p<.05, r=826). Conclusions : Virtual reality-based ADL training can improve ADL performance, but further research is needed to determine whether improvements in social cognition and rehabilitative motivation are possible.

Chin Tuck Against Resistance Exercise(CTARE) and Shaker exercise is used to common for strengthening of suprahyoid muscle. No previous studies was compare of two exercises for patients with dyaphagia. This study investigated the effects of CTARE and Shaker exercise on suprahyoid, sternocleidomastoid muscle activity in stroke older patients with dysphagia. Ten stroke patients with dyaphagia voluntarily participated in this study. All subjects was performed in the order in the CTARE (isometric, isokinetic), Shaker (isometric, isokinetic), and repeated each ten trials. After CTARE was performed, subjects took a 5 min wash out period to minimize muscle fatigue. Activity of suprahyoid and sternocleidomastoid muscle during two training was analyzed using surface electromyography(sEMG). Wilcoxon signed rank test was used to assess differecences for muscles activity between the effects of the CTAR and Shaker exercise within group. CTARE and Shaker exercise showed no significant difference activity in suprahyoid muscle(p > .05). CTARE showed significantly lower muscle activity in sternocleidomastoid muscle than Shaker exercise(p < .05). CTARE in stroke older patients with dysphagia may be a effective intervention to improve swallowing function than Shaker exercise.

In this study, we investigated the effects of five EMS lumbar back pressure belts produced on an anatomical basis on lumbar spine stabilization. Five core muscles were selected, including the urinal, vertebral column, endotracheal, external abdominal, and large back muscles, and patterns were designed using a conductive fabric considering the appropriate muscle shape and pain-causing points. We experimented with four motions to examine the effects of different EMS abdominal compression belts on lumbar spine stabilization. Five healthy men in their 20s were selected. The selection conditions include no back pain history for the past three months, no restricted movements through pre-inspection, and the muscular strength of the body should belong to the normal grade. Using SLR, the sequence of experimental actions was chosen from the following but not limited to left-hand, body-hand, and back-line forces. Resting between movements lasted for 2 min, and the experiments were conducted after wearing the EMS abdominal pressure belt. Electrical stimulation was applied for 10 min to increase blood flow and muscle activation. The statistics of the experimental results were analyzed for specific differences by conducting the Wilcoxon and Friedman tests with nonparametric tests. The ranking results of each pattern were successfully assessed in the order of 5, 4, 3, 1, 2 for the five patterns, and we could identify slightly more significant results for experimental behavior associated with each muscle movement. Patterns produced based on anatomy showed differentiated effects when electric stimulation was applied to each muscle in different shapes, which could improve the stabilization of the lumbar spine in everyday life or training to the public. Based on these results, subsequent research would focus on developing smart healthcare clothing that is practical in daily life by employing different anatomical mechanisms, depending on the back pain, to utilize trunk-type tights.

The South Korean Ministry of Land, Infrastructure, and Transport designated seven automated driving test beds required to evaluate vehicle performance every year for the expansion of mobility services based on automated driving. As a fundamental study, we suggested a necessary example of evaluating the performance with a satisfaction survey for the services before the evaluation. First, we surveyed the perception of automated driving services of users and the public in Sejong-si, South Korea. The survey showed that the users had a higher level of awareness of automated driving technology and intention to use it than the public. Second, the satisfaction survey was conducted on demand-responsive public transportation and automated driving service users. Notably, using the Wilcoxon Rank Sum Test, among the non-parametric statistical analysis methods, we found that safety-related factors affected the overall satisfaction of users of automated driving services. On the other hand, in the case of the demand-responsive public transportation service users, factors related to service convenience affected overall satisfaction. Hence, the results of these surveys are expected to be used as basic data and guidelines to improve the quality of automated driving services and policy establishment.
