Purpose: This study aimed to investigate the application of temperature to balance the training by observing the effect of sensory changes in the foot sole area on dynamic equilibrium ability through change in the sole temperature. Methods: Participants (n=49), who were selected as a certain standard, applied cold and hot packs for ten minutes at two-week intervals, and the laboratory's internal temperature was maintained at $25^{\circ}C$. The subjects were measured before and after the cold and hot applications in the stable condition with bare feet. Before each experiment applied the cold and hot packs, the balance ability of the ordinary temperature was measured once by conducting a limit of stability test using Biorescue, and the changes in balance ability were observed by measuring once after applying the temperature to the foot sole by means of the ice pack and the hot pack. Results: The results of the dynamic balance test, both before and after the temperature application, were compared, and it was confirmed that the moving area before and after cold application decreased significantly, and the moving area before and after application was not significantly different. The mean of pre-post area differences was found to have decreased at a statistically significant rate in the forward, backward, rightward, leftward, and total areas for the group that received the cold application compared to the group that received the hot application. Conclusion: These findings showed that cold application to the foot sole decreased dynamic balance. There was no significant difference in the dynamic balance ability both before and after the hot application to the foot sole, so it is difficult to conclude that the hot application affected dynamic balance.

Purpose: This study aimed to investigate the effect of single-leg stance training according to different support surfaces on walking speed and balance in patients with chronic hemiplegia. Methods: Twenty-two patients with chronic stroke were randomly categorized into an experimental group (11 patients) and a control group (11 patients). In the experimental group, single-leg stance training was performed on an unstable surface after 50 min of general physical therapy. In the control group, single-leg stance training was performed on a stable surface after 50 min of general physical therapy. All participants performed five sets of single-leg stance exercises per minute and rested for 3 min. The intervention was performed 5 times a week for 4 weeks, and each patient was evaluated using the Berg Balance Scale (BBS), Fugl-Meyer Assessment Scale (FMA), and difference in walking speed between the first and last day of the intervention. Results: Compared to baseline measurements, both study groups showed significant increases in FMA, BBS, and walking speed (p< .05) after the intervention. However, there was no statistically significant difference (p >.05) between the experimental and control groups. However, in the experimental group, the increases in FMA, BBS, and walking speed were 3.36 %, 9.50 %, and 7.71 %, respectively. In the control group, the increases in FMA, BBS, and walking speed were 2.39 %, 6.65 %, and 7.64 %. Conclusion: Single-leg stance training on different support surfaces could help improve walking ability and balance in patients with chronic hemiplegia

Purpose : This study examined the effect of locomotive syndrome on stress index and lifestyle patterns among elderly Koreans aged 65 years and older, and analyzed its correlation with stress index and lifestyle patterns. The purpose of this study was to provide basic data for the management and prevention of locomotive syndrome in the elderly. Methods : Using the “25-Question Geriatric Locomotive Function Scale (GLFS-25)”, the study evaluated locomotive syndrome in 123 elderly Koreans aged 65 years and older. Of them, 85 patients were assigned to the locomotive syndrome group and 38 patients were assigned to the normal group. The questionnaire measured and investigated the participants’ stress index and lifestyle patterns. Statistical analysis was performed using SPSS 22.0 ver. Results : Results showed the locomotive syndrome group displayed a higher stress index than the normal group, with a statistically significant difference between the two groups. The group also scored lower in the lifestyle pattern survey than the normal group did, with a statistically significant difference in high-intensity work performance ratio and average daily performance time between them. The GLFS-25 score showed a significant positive correlation with the stress index and sitting and lying down time, and a significant negative correlation with medium-intensity working time, walking, and cycling time. Conclusion : In conclusion, Locomotive syndrome in elderly Koreans is closely related to stress and lifestyle patterns, especially high-intensity work. We recommend active prevention and management of locomotive syndrome and further research into the effects of various lifestyle factors on the illness.

실험계획법을 이용한 TCP 데이타 부분에 대한 상호운용성 시험스위트 생성

유지원(Jiwon Ryu),김명철(Myungchul Kim),설순욱(Soonuk Seol),강성원(Sungwon Kang),이영희(Younghee Lee),이근구(Keunku Lee) 한국정보과학회 2001 정보과학회논문지 : 정보통신 Vol.28 No.2

통신 프로토콜의 상호운용성을 시험하기 위한 시험경우를 생성하는 방법론이 논문 [1, 2, 3]에서 제안되었고 TCP와 ATM 프로토콜에 적용되었다. 이들 방법론으로 생성된 시험경우는 제어 부분만을 고려하고 있다. 그러나 실제 시험에 있어서는 데이타를 고려하여야 하며, 완전한 시험이 되기 위해서는 이들 변수들이 가질 수 있는 모든 값에 대한 시험을 거쳐야 하지만 이것은 현실적으로 불가능하다. 본 논문에서는 데이타를 포함하는 시험을 하기 위하여 논문 [1]에서 도출한 시험경우에 제어 부분과 데이타 부분을 동시에 고려하여 TCP의 연결 설정 절차에 대한 시험경우를 도출한다. 이 과정에서 시험경우의 수가 너무 커지는 것을 피하기 위해 최소의 실험횟수로 최대의 정보를 얻을 수 있도록 실험계획법(experimental design)을 이용한다. 실험계획법은 적합성 시험에는 적용되었지만 아직 상호운용성 시험에는 적용되지 않았다. 이 방법을 통해 데이타 부분을 포함하는 상호운용성 시험경우를 생성하고, 시험의 검출력 (power of test)을 유지하면서 최소화된 시험경우로 상호운용성 시험을 할 수 있는 가능성을 보인다. Test derivation methods suitable for interoperability testing of communication protocols were proposed in [1, 2, 3] and applied to the TCP and the ATM protocols. The test cases that were generated by them deal with only the control part of the protocols. However, in real protocol testing, the test cases must manage the data part as well. For complete testing, in principle we must test all possible values of data part although it is impractical to do so. In this paper, we present a method generating the interoperability test suite for both the data part and the control part of protocols with the example of TCP connection establishment. In this process, we make use of experimental design techniques from industrial engineering to minimize the size of test suite while keeping testing capability. Experimental design techniques have been used for protocol conformance testing but not for interoperability testing so far. We generate the test suite for data part by this method and show a possibility that we can test interoperability of protocols with the minimum number of test cases while maintaining the testing power.
