Purpose: The purpose of this study was to examine the influence of multi-directional dynamic stabilization exercise on the thickness of the external oblique abdominis, internal oblique abdominis, and transversus abdominis. Methods: For the study subjects, 40 adults were taken and divided into two groups and stabilization exercise was performed for 6 weeks. Changes in muscle thickness during the pre-experimental period, and at 2 weeks, 4 weeks, and 6 weeks were analyzed using repeated ANOVA. Results: The thickness of the external oblique abdominis, internal oblique abdominis, and transversus abdominis in the multi-directional dynamic stabilization exercise group showed significant differences per period and an interaction was observed between period and group (p<0.01), while there were no significant differences in changes per group (p>0.05). Conclusion: The effects of multi-directional stabilization exercises on abdominal muscle thickness differed. The results presented herein can be utilized as basic data for future studies and in development of rehabilitation treatments.

The purpose of this study is to examine the changes on lumbar muscle strength in relation to 12-week pilates mat exercise of elderly women. The participants are chosen for 17 people who is an experimental group and 14 people who is an comparison group who except wastage and pilates mat exercise program was gradually intensify applied three times a week, during 12 weeks. The peak torque of flexion was increased(p<.01) and the difference of ratio of agonist to antagonist was decreased(p<.001). The total work of flexion and extension had significant increased(p<.001) at $120^{\circ}/sec$. As a result of all these, it was judged as positive effect for body composition, basal physical fitness and lumbar muscle strength after pilates mat exercise in 12 weeks. These positive effects showed that pilates mat exercise could got conclusions that mitigated the musculoskelctal disorders, slow down the progress of disorders, helped as a functions of physical.

A diabetes self-management serious game, 'Roly Poly 160' is developed for Type II diabetes patients to decrease their blood Sugar level. For verifying the effectiveness of 'Roly Poly 160', we examined the satisfaction survey. Data were collected from the diabetes patients and public those who have used 'Roly Poly 160' through D Community health center and S Community health center in Gwangju, from November, 27, 2018 to December, 4, 2018. 67 people returned the survey through the 'Roly Poly 160' APP. The overall average satisfaction level was 3.7 out of 5.

RFID is rising as a means which recognizes products efficiently and correctly. The use of RFID technology can reduce the expense of excess stocktaking, forgery, labor and improve supply network. RFID technology uses RF to recognize the products. EPC, a small tag, is attached to each product, which includes specific product information. Each EPC is only one and can recognize each product. If EPC tag moves to a specific location, the reader reads the tag, the data of which get to be stored in EPC information service, a data storage system. All services can approach EPC information service through web and whenever users demand services, they are provided with the data they want. This study shows an inventory control system is implemented by EPC information service.

Purpose : The purpose of the present study was to investigate the effects of ballistic stretching techniques on the flexibility, muscle strength and electrophysiologic nature. Methods : The subjects of the study were 20 young adults including 10 for the ballistic-stretching group, and 10 for the control group. This study measured hamstring flexibility, muscle strength, median frequency and root mean square on electromyography signals. All measurements were analyzed using independent sample t-tests. Results : VAS, FPRS, and ODI showed significant pain decrease in all groups except for the ODI measurement in the 0.5㎐ group. There were no significant differences according to frequency levels. Conclusion : It was understood that the effect of stretching was greater when performing ballistic stretching techniques.

At present, with the rise of smart-phone market supported the Wi-Fi, smart-phone based network content has propagated rapidly. But, network content service is difficult in feature phone and multimedia device not supporting the Wi-Fi or supporting only the bluetooth. This paper was used the zigbee technology supporting low power, low cost, availability, multi channel, broadcasting compared to the bluetooth or Wi-Fi. It will provide a variable network game development by utilizing the zigbee technology. Also, it is provide the development of variable mobile network contents using the zigbee.

Purpose: The present study was to examine the effects of a communication training program on nursing students' interpersonal communication and relationships. Methods: This study was quasi-experimental research using a non-equivalent pre-post design. The subjects were 40 sophomore nursing students who were divided into an experimental group of 20 members and a control group of 20 members. The communication training program consisted of 8 sessions of small group training and each session lasted 120 minutes. A pretest, posttest and follow-up test (6 months after the program was terminated) were conducted to measure Inter-personal Communication Inventory and Relationships Scale. Data was analyzed by $X^2$-test, independent t-test, paired t-test and Friedman test with SPSS. Results: The communication training program was very effective in enhancing the nursing students' communication and interpersonal abilities. Nursing students' communication ability in the experimental group, however, decreases after 6 months while there is no change in the control group. Nursing students' interpersonal relationships in the experimental group was maintained at the follow-up test. Conclusions: This study supports that a communication training program has a positive effect on improving the nursing students' communication skill and interpersonal relationships.

This study aims to suggest a rural village development policy considering tourists' stay pattern and villages' resources which can be infrastructure for green-tourism. For this purpose, a relationship table between amenity resources and the stay pattern was developed as a guide line to combine a set of several facilities fer village renewal. The amenity resources system was classified into three sub-classes(social, industrial, and natural/cultural/historical resources) and a relationship diagram between three classes and tourists' behavior was also defined. The table and diagram were applied to make renewal plan for 40 rural villages of the study area, Bukmyun, Cheonan, Chungnam province, so that the development scheme for the villages was suggested reasonably by the new findings of this study.

Purpose: The purpose of this study was to compare the effects of scrambler and transcutaneous electrical nerve stimulation therapy on pain, functional disability, and depression in patients with chronic low back pain. Methods: Twenty patients with chronic stroke were assigned randomly to an experimental (n=10) or control (n=10) group. The experimental group performed scrambler therapy. The control group performed electrical nerve stimulation therapy. Training was conducted once a day for 30 minutes, five days per week, for three weeks. The pain was measured using the numeric rating scale. Functional disability was measured using the Roland-Morris disability questionnaire. Depression was measured using the Beck depression inventory. Results: As a result of comparison between the groups, the experimental and control groups showed significant difference for pain, functional disability and depression after the experiment (p<0.05). In a comparison between the two groups, the experimental group, in which scrambler therapy was applied, showed a more significant reduction in pain, functional disability and depression than the control group (p<0.05). Conclusion: Based on these results, scrambler therapy shows positive effects on pain, functional disability, and depression in patients with chronic low back pain.
