PURPOSE: This study was to investigate the effect of stabilization exercise with abdominal breath on Balance and Oswestry Disability Index for Low Back Pain Patients. METHODS: The subjects were 18 low back pain patients in their twenties. The subjects were randomly assigned into experimental group and control group. Control group and experimental group both participated in 30 minutes of stabilization exercise for 8 weeks(5 times/week), and experimental group participated in stabilization exercise with abdominal breath. The subjects were tested balance and pain using BioRescue and Oswestry Diability Index respectively, before and after intervention. RESULTS: The experimental group showed a statistical significance in movement areas of the body's center(p<.05), but there was no significant differences between groups (p>.05). The experimental group showed a statistical significance in movement distances of the body's center with eyes open(p<.05), and there was significant differences between groups(p<.05). Both groups showed a statistical significance in ODI between pre and post test(p<.05) but there was no significant differences between groups(p>.05). CONCLUSION: As a result, the group participating in stabilization exercise with abdominal breath had a more effective improvement than the control group. Therefore, the stabilization exercise with abdominal breath may be used improving balance and pain in low back pain patients.

The inverse correlation between maternal age and pregnancy rate represents a major challenge for reproductive endocrinology. The high embryo ploidy error rate in failed in vitro fertilization (IVF) cycles reflects genetic misfires accumulated by older oocytes over time. Despite the application of different follicular recruitment protocols during IVF, gonadotropin modifications are generally futile in addressing such damage. Even when additional oocytes are retrieved, quality is frequently poor. Older oocytes with serious cytoplasmic and/or chromosomal errors are often harvested from poorly perfused follicles, and ovarian vascularity and follicular oxygenation impact embryonic chromosomal competency. Because stimulation regimens exert their effects briefly and immediately before ovulation, gonadotropins alone are an ineffective antidote to long-term hypoxic pathology. In contrast, the tissue repair properties (and particularly the angiogenic effects) of platelet-rich plasma (PRP) are well known, with applications in other clinical contexts. Injection of conventional PRP and/or its components (e.g., isolated platelet-derived growth factors as a cell-free substrate) into ovarian tissue prior to IVF has been reported to improve reproductive outcomes. Any derivative neovascularity may modulate oocyte competence by increasing cellular oxygenation and/or lowering concentrations of intraovarian reactive oxygen species. We propose a mechanism to support intrastromal angiogenesis, improved follicular perfusion, and, crucially, embryo ploidy rescue. This last effect may be explained by mRNA upregulation coordinated by PRP-associated molecular signaling, as in other tissue systems. Additionally, we outline an intraovarian injection technique for platelet-derived growth factors and present this method to help minimize reliance on donor oocytes and conventional hormone replacement therapy.

Recently, rapid spreading of smart-phone make an expectation for increase of practical application for MANET(Mobile Ad-Hoc Network) which is not used infrastructure like as base-station. One of important application for MANET will be VoIP(Voice over Internet Protocol) known as Internet telephony. On the other hand, information intrusions causing serious problems is not allowed exception of MANET. Especially, there are some dangerous problems of intrusions to MANET, differently to other networks, because of it's usage of military purpose or emergency application of rescue. In this paper, to analyze this intrusion problem on MANET with blackhohe attacks, effect of intrusion to transmission performance is studied. VoIP traffic is assumed as an application service on MANET, computer simulation with NS-2 is used for this analysis.

This paper presents fatigue analysis of helideck structures located in FPSO. After FPSO is moved to the target position where production of resource is performed, FPSO stays at the target position and performs production of resource, storage and off-loading during the design life. Helideck structure is located in FPSO essentially for the movement of personnel and life rescue at emergency situations by using helicopters. Because inertial load induced by FPSO motion and landing and taking-off load of helicopter occur at helideck structures cyclically, helideck structures should be designed to withstand fatigue loads. Therefore, The fatigue assessment of helideck structures should be performed with fatigue loads. Effect of stress concentration due to misalignment between welded plates is considered in fatigue assessment additionally.

Purpose: We aimed to provide effective emergency medical services (EMS) response strategies for coping with high acuity patients during the pandemic by analyzing the influence of the COVID-19 and social distancing on EMS. Methods: In this retrospective observational study, we analyzed the distribution of high acuity patients transported by Daejeon 1-1-9 EMS during the COVID-19 pandemic period, between February 1, 2020 and October 31, 2020 and the same period in 2019, as well as the level 3 social distancing enforced period, between July 27, 2020 and October 31, 2020. Results: The EMS dispatches decreased by 17% during the observed COVID-19 pandemic period compared to the same period in 2019. The number of cases with cardiac arrest and positive prehospital stroke scale rose by (p<.001). Patients with cardiac arrest, trauma, and positive prehospital stroke scale increased by during the level 3 social distancing period. Conclusion: Unlike the decreased EMS call volume and patient transports during the COVID-19 pandemic, cardiac arrest cases and the severity of high acuity patients tended to increase. We suggest that EMS systems should contrive a response strategy considering the collateral effect of major epidemics on the incidence rate of high acuity patients.

The purpose of the study is to examine the visual evaluation of bleeding amount in hemorrhagic shock in paramedic students. Through manikin simulation training, paramedic students were able to have confidence with estimation of bleeding amount in the prehospital settings. Three rescue training manikins were placed in supine position and artificial blood was poured between the abdomen and pelvis. The bleeding evaluations of 700 mL, 1200 mL, and 1700 mL were performed before and after simulation training. Paramedic students underestimated the amount of bleeding in the trauma situation, and it was found that it was difficult for the students to evaluate the accurate amount of bleeding with a single simulation.

Previous studies have uncovered the role of circ_0000144 in various tumors. Here, we investigated the function and mechanism of circ_0000144 in gastric cancer (GC) progression. The expression of circ_0000144 in GC tissues and cells was detected through quantitative real-time polymerase chain reaction (qRT-PCR) method. Gain- and loss-of-function experiments including colony formation, wound healing and transwell assays were performed to examine the role of circ_0000144 in GC cells. Furthermore, western blot was conducted to determine the expressions of epithelial mesenchymal transition (EMT)-related proteins. The interaction between circ_0000144 and miR-217 was analyzed by bioinformatic analysis and luciferase reporter assays. The circ_0000144 expression was obviously upregulated in GC tissues and cells. Silencing of circ_0000144 inhibited cell proliferation, migration and invasion of GC cells, but ectopic expression of circ_0000144 showed the opposite results. Moreover, circ_0000144 sponged miR-217, and rescue assays revealed that silencing miR-217 expression reversed the inhibitory effect of circ_0000144 knockdown on the progress of GC. Our findings reveal that circ_0000144 inhibition suppresses GC cell proliferation, migration and invasion via absorbing miR-217, providing a new biomarker and potential therapeutic target for treatment of GC.

PURPOSE: This study examined effects of the untact trunk stabilization exercise program on muscle thickness, trunk strength, maximal expiratory flow, and static balance. METHODS: The subjects were 20 normal adults divided into 10 in the contact exercise group and 10 in the untact exercise group. The trunk stabilization exercise program was conducted for four weeks. The muscle thickness was measured using ultrasound. The maximal expiratory flow was measured using Personal Best Full Range Peak Flow Meter. The static balance was measured through Bio-rescue; and the trunk muscle strength was measured by bending the upper body forward and measuring the time for maintaining the posture. RESULTS: Both contact and untact exercise groups showed significant differences in muscle thickness, muscle strength, maximal expiratory flow, and static balance (p < .05). A significant difference in muscle thickness on ultrasound was observed between the contact and untact exercise groups (p < .05). CONCLUSION: Activation of the transverse abdominal muscle requires accurate instructions of the contact exercise, but despite environmental constraints, the untact exercise program is as effective as the contact exercise for improving muscle strength, maximum expiratory flow, and static balance.

Purpose: This study explored the impact of using a music and horticultural therapy program on depression among rural seniors living in Yeongam-gun and conducted a comparative analysis before and after the program to present basic data helpful for an integrated mental health promotion program tailored to rural areas. Research methodology: The analysis subjects of this study were users of the rural residential program of 'Our Village Day Care Center' in Yeongam-gun in 2023, with a total of 20 people, 10 seniors for each program. The research analysis used SPSS to determine the effect on participation and depression before and after the program was implemented. Results: As a result of the analysis, depression levels decreased after completion of the horticultural therapy program and music therapy program, and this was statistically significant. Conclusion: Three implications are presented based on the following research results. First, the need for programs that can improve not only the physical health but also the mental health of elderly people living in rural areas is suggested. Second, the need for programs that link cultural programs such as music and gardening activities with welfare programs is suggested. Third, the need for follow-up management and verification of periodic mental health checkups for rural elderly is suggested.
