The hamonious development of human brain has been an indigenous objective of each age. A variety of training programs related to the purpose have turned up at an educational market and a commercial market, as well. I'd like to indicate, however, that these training methods are somewhat prejudiced and have some elements, inherently, which are against the development of human brain for one's whole personality. Therefore, the most desirable brain training program is to induce it to respond to various stimuli, to educate for itself and to generate continuously, to create and strengthen an innumerous synapse among brain cells, so as to form a nero-network. In this study, I have used a brain training program with multimedia which have been produced for a specific purpose. With this method, by measuring directly the effectiveness of human brain development, I have analysed more objectively and more quantitatively.

The user valence of VoIP services with SIP protocol is increasing rapidly because of cheap communication cost and its conveniency. But attacker can easily modify the packet contents of SIP protocol as SIP header is transmitted by using UDP methods in text form. The reason is that SIP protocols does not provide an authentication function on the transmission session. Therefore, existing SIP protocol is very weak on SIP Packet Flooding attack etc. In order to solve like this kinds of SIP vulnerabilities, we used SIP status codes under the monitoring module for detecting SIP Flooding attacks and additionally proposed an advanced protocol where the authentication and security function is strengthened about SIP packet. We managed SIP session spontaneously in order to strengthen security with SIP authentication function and to solve the vulnerability of SIP protocol. The proposed mechanism can securely send SIP packet to solves the security vulnerability with minimum traffic transmission. Also service delay in SIP proxy servers will be minimized to solve the overload problem on SIP proxy server.

Background: Lumbopelvic stability is highly important for exercise therapy for patients with low back pain and shoulder dysfunction. It can be attained using a pelvic compression belt. Previous studies showed that external pelvic compression (EPC) enhances form closure by reducing sacroiliac joint laxity and selectively strengthens force closure and motor control by reducing the compensatory activity of the stabilizer. In addition, when the pelvic compression belt was placed directly on the anterior superior iliac spine, the laxity of the sacroiliac cephalic joint could be significantly reduced. Objects: This study aimed to compare the effects of EPC on lumbopelvic and shoulder muscle surface electromyography (EMG) activities during push-up plus (PUP) and deadlift (DL) exercise, trunk extensor strength during DL exercise. Methods: Thirty-eight subjects (21 men and 17 women) volunteered to participate in this study. The subjects were instructed to perform PUP and DL with and without the EPC. EMG data were collect from serratus anterior (SA), pectoralis major (PM), erector spinae (ES), and multifidus (MF). Trunk extensor strength were tested in DL exercise. The data were collected during 3 repetitions of all exercise and the mean of root mean square was used for analysis. Results: The EMG activities of the SA and PM were significantly increased in PUP with pelvic compression as compared with PUP without pelvic compression (p<.05). In DL exercise, a significant improvement in trunk extensor strength was observed during DL exercise with pelvic compression (p<.05). Conclusion: The results of this study indicate that lumbopelvic stabilization reinforced with external pelvic compression may be propitious to strengthen PUP in more-active SA and PM muscles. Applying EPC can improve the trunk extensor strength during DL exercise. Our study shows that EPC was beneficial to improve the PUP and DL exercise efficiency.

Background: Stretch-oriented home exercise programs are often used as treatments for patients with adhesive capsulitis; however, there is lack of research on home exercise programs to strengthen rotator cuffs. Objects: The aim of this study is to investigate the effect of home exercise programs for rotator cuff strengthening on pain, range of motion (ROM), disability level, and quality of life in patients with adhesive capsulitis. Methods: Twenty-two patients with adhesive capsulitis volunteered to participate in this study. The subjects were randomly divided into an experimental group (n = 11) and control group (n = 11). For the experimental group, manual therapy and home exercise programs for rotator cuff strengthening were applied for 6 weeks; for the control group, only manual therapy was applied for 6 weeks. Shoulder pain (quadruple visual analogue scale, QVAS), ROM, disability (shoulder pain and disability index-Korean version, SPADI), and quality of life (world health organization quality of life scale-Korean version, WHOQOL-BREF) were evaluated at baseline, after 3 weeks, and after 6 weeks of intervention. The changes in the measurement variables were analyzed by using repeated measure analysis of variance. Results: Significant differences were observed between the experimental group and control group in the QVAS; SPADI-pain scores; SPADI-disability scores; SPADI-total scores; flexion, abduction, internal and external rotation ROM of the glenohumeral joint; and WHOQOL-BREF total, overall, physical health, and psychological scores. All groups displayed statistically significant improvements as observed in the QVAS, SPADI, flexion, abduction, external and internal rotation ROM of the glenohumeral joint, and WHOQOL-BREF. Conclusion: Home exercise programs for rotator cuff strengthening had a positive impact on shoulder pain, shoulder ROM, disability level, and quality of life in patients with adhesive capsulitis. Therefore, we propose the use of home exercise programs for rotator cuff strengthening in the exercise rehabilitation of patients with adhesive capsulitis.

Purpose: This study was conducted to investigate changes in cognitive functions, depression and life-satisfaction for elderly participants with mild cognitive impairments participating in an individual cognitive improvement program. Methods: A quasi-experimental with non-equivalent control group pretest-posttest design was implemented. The participants were senior citizens over 65 years of age who had been clinically diagnosed with mild cognitive impairments in G City and J Province (experimental group: 29, control group: 27). The experimental group participated in the individual cognitive improvement program based on Korean traditional tales and games for nine weeks. Results: After the intervention, only the participants in the experimental group reported significant improvement in K-MMSE (t=-2.5, p=.016), MoCA-K (t=-2.6, p=.008), depression (t=3.51, p=.001), and life satisfaction (t=-2.75, p=.008) when compared to those in the control group. Conclusion: These results indicated that the individual cognitive improvement program was effective in improving cognitive functions, depression, and life-satisfaction among the elderly with mild cognitive impairments. Therefore, the application of this individual cognitive improvement program developed in this study by visiting nurses may strengthen the cognitive functions of seniors with mild cognitive impairments.

Purpose: This study aimed to identify variables influencing the health-related quality of life (HRQoL) of adults with epilepsy in order to establish a structural model and design an intervention strategy to improve patients' HRQoL. Methods: The selected subjects were 212 patients with epilepsy aged between 18 and 70 years who were currently receiving treatment from hospital, general hospital, and clinic. They were surveyed using a structured questionnaire. Results: The goodness of fit measures of the final hypothetical model were as follows: ${\chi}^2/df=2.51$, GFI=.91, AGFI=.90, CFI=.96, SRMR=.04, NFI=.93, and RMSEA=.08. The major variables influencing the HRQoL of adults with epilepsy were epilepsy self-efficacy, depression, social support, and side effects of anti-epileptic drugs (AEDs), which were significant in the mentioned order, whereas the duration of AEDs use and perceived stigma did not show any effects. Six variables accounted for 75.6% of HRQoL. Variables having a direct and total effect on the HRQoL of adults with epilepsy were the side effects of AEDs, social support, epilepsy self-efficacy, and depression, and those with an indirect effect were the side effects of AEDs and social support. Conclusion: It is necessary to accurately identify the side effects of AEDs in adults with epilepsy and accurately observe the physical changes caused by depression. In addition, it is imperative to establish an active and effective nursing intervention program to strengthen the self-efficacy of the patients and to improve their quality of life through social support provided by family members and medical professionals.

Knowledge management becomes the key point for organizations to survive and maintain competitive advantages in the knowledge economy era. E-learning plays a vital role for the organizational learning. How to share the experience of knowledge and the success of the knowledge management has great connection with the organizational culture. This study focuses on the factors of effective E-learning as well as its relation to the organizational culture. A successful e-learning system should not only aim at different statistical variables but emphasize on : course contents, variety of teaching methods and establishes a stable network environment. A stable E-learning platform and speedy bandwidth is a must to achieve the non-barrier communication and built an interactive learning environment. To achieve success in E-learning, it is not necessary to divide the organizational culture to strengthen the course content multiplication and plans the E-learning supervisory work by the sole responsibility unit. It should establish an ample teaching frequency width and platform and also must establish the appropriate study network frequency width and hardware equipment to achieve the best E-learning effect. The interaction in different organizational culture in adapting E-learning, those Ad-hoc and Marketing Culture, are mostly influence by the external environment and have more interactive content. Those in Clan and Hierarchy Culture are affected by traditional conception and lack of interaction. Meanwhile, under the cost consideration, Clan and Ad-hoc Culture on the dynamic side prefer to spend more cost on E-Learning while the stable side, Hierarchy and Marketing culture are willing to pay more expenses on E-Learning.

Purpose: As emergency medical service fund is further expanded due to amendment of the law on emergency medical services in 2008, Korean government has prepared to intervene in a comprehensive manner to strengthen a trauma treatment system. As a result, it announced a master plan to establish a serious trauma treatment center in 16 areas across the nation. Therefore, this study has attempted to investigate the current status of the serious trauma treatment centers and suggest the goal and improvement plan of future serious trauma treatment centers. Methods: As of 2011, Korea operates 23 emergency cerebrovascular service centers, 23 emergency heart disease centers and 35 severe trauma treatment centers across the country. 12 emergency medical service centers have been chosen among the serious trauma treatment centers. Then, top six (6) centers chosen at Emergency Medical Institute Assessment 2011 by Ministry of Health and Welfare have been selected, and floor layout and spatial allocation by usage have been reviewed and analyzed. Results: Consequently, this study has investigated the spatial components, circulation layout and spatial allocation of a serious trauma treatment. For construction planning in consideration of the fundamental objectives and goal of emergency medical services, it is essential to allot spaces and select exact spatial components. It appears that it is necessary to design spaces for emergency medical services and come up with construction planning through appropriate spatial allocation.
