PURPOSE: This pre-post intervention study aimed to examine the effects of a 12-week supervised modified Taekwondo exercise program on the functional fitness of community-dwelling older adults. METHODS: 10 participants (mean age: 72.3 ± 4.6 years) completed the program over a 12-week period. The intervention consisted of Taekwondo-based exercises modified for older persons. Changes to functional fitness were measured using the finger-to-nose test, functional reach test, timed up and go test, 30-second sit-to-stand test, 30-second arm curl test, Chester step test, chair sit-and-reach test, and back scratch test. Participants were assessed prior to the training and after the final training session, changes were measured using descriptive statistics and paired sample 't' tests. RESULTS: Effect sizes ranged from small to large (Cohen's d = .22 to 1.23). The exercise program was well- tolerated by participants, with a high level of engagement and no attrition for the duration of the program. Results showed significant improvements in most measures of functional fitness (p < .05) except for the back scratch test (p = .051). CONCLUSION: These findings suggest a well-designed, supervised, modified Taekwondo exercise program can significantly improve functional fitness in older adults.

Advanced SITs of the evolutionary PWRs have the advantage that they can passively control the ECC water discharge flow rate. Thus, the LPSI pumps can be eliminated from the safety injection system owing to the benefit of the advanced SITs. In the present study, a passive sealing plate was designed in order to overcome the shortcoming of the advanced SITs, i.e., the early nitrogen discharge through the stand pipe. The operating principle of the sealing plate depends only on the natural phenomena of buoyancy and gravity. The performance of the sealing plate was evaluated using the VAPER test facility, equipped with a full-scale SIT. It was verified that the passive sealing plate effectively prevented the air discharge during the entire duration of the ECC water discharge. Also, the major performance parameters of the advanced SIT were not changed with the installation of the sealing plate.

In the modern society, social activities of married women are increasing along with the economic growth, which leads to low birth rates of the situation where most people give birth to only one or two children. Korea in particular records one of the lowest birth rates among many other nations of the world. Despite the situation where overall industrial consumer economy is not good, baby goods market is becoming more luxurious and diversified, and its scale is also growing. Desires of young parents in their 20s and 30s for their children leads to consumption desires of luxurious baby goods, and despite the fact that their taste level rises by easily gaining access to immense baby information via the Internet, our nation's baby furniture market is unreasonably lacking the ability to satisfy the needs of such consumers. Furniture culture of our nation today is based on the stand-up culture of the West. However, analyzing the life culture inside our homes, stand-up and sit-down cultures of the West and the East are coexisting complexly. Such life pattern can be more easily found in households with babies. As such, baby furniture that satisfies our unique life culture and has quality, design and price competitiveness is desperately needed. In such market state, this study is expected to make economic and cultural accomplishments by focusing on the newly embossing baby furniture market and developing products, delivering them to consumers to open new markets and developing into an industry.

The purpose of this case report is to investigate whether an attempt to hold the repeated upright posture under blocking the patient's vision affects the deficits to push away from the paralytic side and the relapse time from down to stand up position without push away in patients with hemiplegia with pusher syndrome. Two hemiplegic patients with pusher syndrome were assessed. The task was performed 4 times per day for 6 weeks. The modified barthel index (MBI) was performed to assess activities of daily living (ADL). For assessing balance, the "balanced sitting" and "sit to stand" are analyzed using by modified motor assessment scale (MMAS). The scale for contraversive pushing (SCP) was used for determination of push away from paralyzed side. MBI, MMAS and SCP were assessed before and after trial of the task. In patient 1, total score of the scale is 0 in sitting posture and standing posture within 3 weeks and 4 weeks, respectively, In patient 2, total score of the scale is 0 in sitting posture and standing posture within 4 weeks and 6 weeks, respectively. These results demonstrated that pusher syndrome was completely resolved in at least 6 weeks. Our findings indicate that this physical therapy seems to be relevant for the hemiplegic patients with pusher syndrome.

The purpose of this study was to determine how smartphone use posture affects biomechanical variables and muscle activities. Eleven university students(age: $22.2{\pm}2.6$ yrs, height: $176.6{\pm}4.7$ cm, weight: $69.5{\pm}7.5$ kg) who have no musculoskeletal disorder were recruited as the subject according to having experience in using the smartphone for more than one year. Angular velocity, muscle activity, and thumb finger pressure were determined for each trial. For each dependent variable, a one-way analysis of variance (ANOVA) with repeated measures was performed to test if significant difference existed among different three conditions (p<.05). The result showed that rotational angular velocity of the first metacarpal were increased in DESK posture compared with STAND posture during SU phase. The average nEMG values of FDI(First dorsal interosseous) were less in SIT and DESK posture compared with STAND posture during SR phase. These indicated that smartphone postures may effect the thumb ROM(Range of motion) and muscle activity. This has led to suggestions of the need for further kinetic and EMG analyses to evaluate best assess and characterize with smartphone use.

Purpose: This study examined the effects of an exercise program involving the Proprioceptive Neuromuscular Facilitation (PNF) lower-extremity patterns on the Bone Mineral Density (BMD), balance and lower muscular strength in patients with osteoporosis. Methods: The participants were allocated randomly to 2 groups: experimental group and control group. To evaluate the effects of exercise, the subjects were evaluated using the BMD and Time Up & Go Test and One Leg Stance Test for balance, and the Sit To Stand for lower muscular strength. Results: After the 8 week study, the experimental group showed a significant difference in all items compared to the control groups. Conclusion: These results suggest that a PNF exercise program is effective in patients with osteoporosis. Furthermore, an exercise program involving these patterns can be used in a follow-up program for patients with osteoporosis. Overall, more study will be needed to develop and apply more efficient exercise programs for such patients.
