Sahmyook University is a private, Christian, coeducational university located in Metropolitan Seoul, South Korea. Sahmyook University is part of a worldwide network of Seventh-day Adventist institutions of higher education providing an environment for learning that emphasises individual commitment to Christ, personal integrity, intellectual development, and community service. The school was founded in 1906 as Euimyung College in Sunahn, Pyeongan-namdo in what would become today's North Korea. It was the first higher education facility started in Korea, and is today the largest university owned by the Seventh-day Adventist Church.In 2009, the university had 6 colleges, including the College of Theology, Humanities & Social Science and Health Science & Social Welfare in addition to 4 graduate schools. There are 216 full-time faculty teaching 5,566 undergraduate students and 189 graduate students. Wikipedia.

Sliding window equijoins are commonly used in data stream applications. In their implementation, a hash table is generally allocated for each stream source. However, this structure may degrade join performance because all tuples in the hash tables need to be scanned to find expired tuples whenever windows are updated periodically. This paper presents an alternative structure to improve the performance of sliding window equijoins. The basic idea of the proposed method is to allocate a hash table for each set of tuples arriving for a window slide interval. This organization facilitates the identification of expired tuples and improves the join performance, which we observed through our experimental results. © 2013 IEEE.

The purpose of this paper is to verify the relationships among service quality, perceived value, customer satisfaction, and customer loyalty in mobile phone service. The study conducted an empirical research. A total of 384 mobile phone users' responses were collected from Seoul in Korea. The findings show that service quality positively influences customer loyalty. In addition, perceived value and customer satisfaction positively affects customer loyalty respectively. For customers with high perceived service quality, perceived value, and satisfaction, they have a strong loyalty. © Hyung Seok Lee, 2010.

Objective: The purpose of this study was to examine the feasibility of core stabilization exercise with real-time feedback on balance and gait function in patients with chronic hemiparetic stroke. Methods: Nineteen stroke subjects were enrolled in this study. The patients were randomly divided into the experimental (n = 10) and control groups (n = 9). Subjects in the experimental group performed core stabilization exercise with real-time feedback training for 30 minutes per day during a period of six weeks. Subjects in the control group performed core stabilization exercise during the same period. This study assessed the kinematic parameters using a portable walkway system, and timed up-and-go test. Results: Gait velocity showed significantly greater improvement in the experimental group (7.3 ± 5.0 sec) than in the control group (-0.7 ± 10.6). Stride length showed significantly greater increase in the experimental group (13.2 ± 7.9 on the affected side and 12.6 ± 8.0 on the less affected side) than the control group (3.5 ± 8.7 on the affected side and 3.4 ± 8.5 on the less affected side). After training, change in results on the timed up and go test was significantly greater in the experimental group than in the control group. Conclusion: Core stabilization exercise using real-time feedback produces greater improvement in gait performance in chronic hemiparetic stroke patients than core stabilization exercise only. © 2014 - IOS Press.

The purpose of this study was to investigate the effectiveness of the virtual walking training program using a real-world video recording on walking balance and spatiotemporal gait parameters in patients with chronic stroke. Fourteen patients with chronic stroke were randomly assigned to either the experimental group (n = 7) or the control group (n = 7). The subjects in both groups underwent a standard rehabilitation program; in addition, the experimental group participated in the virtual walking training program using a real-world video recording for 30 mins a day, three times a week, for 6 wks, and the control group participated in treadmill gait training for 30 mins a day, three times a week, for 6 wks. Walking balance was measured using the Berg Balance Scale (BBS) and the Timed Up and Go test. Gait performance was measured using an electrical walkway system. In walking balance, greater improvement on the Berg Balance Scale (experimental group: 4.14 vs. control group: 1.85) and the Timed Up and Go test (-2.25 vs. -0.94) was observed in the experimental group compared with the control group (P <; 0.05). In the spatiotemporal gait parameters, greater improvement on velocity (25.40 vs. 9.74) and cadence (26.71 vs. 11.11) was observed in the experimental group compared with the control group (P <; 0.05). This study demonstrated the positive effects of the virtual walking training program using a real-world video recording on gait performance. These findings suggest that the virtual walking training program using a real-world video recording may be a valid approach to enhance gait performance in patients with chronic stroke.
