Objective: To study the effects of gait training with additional weight and gait training with non-additional weight on balance ability and gait ability in patients with chronic stroke through comparative analysis. Design: Randomized controlled trials. Methods: The subjects were divided randomly into two groups: additional weight group (AWG, n=12), and non-additional weight group (NAWG, n=10). Both groups received general physical therapy for 30 min in 1 session, 5 sessions per week during 6 months. The AWG practiced gait training with additional weight of 0.1 and 0.5 kg for 20 min a day, 3 days per week for 6 months and the NAWG practiced gait training with non-additional weight for 20 min a day, 3 days per week for 6 months. Patients in both groups were instructed to walk as fast as they could along a 35 m long track (straight for 20 m and curved for 15 m). Patients walked with their hemiplegic side on the inside of the track while a physical therapist followed along to instruct patients to maintain a straight posture. Balance ability was tested with the Functional Reach Test, the Timed Up and Go test, and the Berg Balance Scale, and gait ability was tested with GAITRite. The results of balance and gait ability were analyzed before and after interventions. Results: A significant increase in FRT, TUG, BBS was seen in both groups after intervention (p<0.05). A significant increase in gait ability was seen in the AWG after intervention (p<0.05). For balance and gait ability, the results from the AWG was significantly improved compared with the NAWG (p<0.05). Conclusions: Gait training with additional weight improves balance ability and gait ability in stroke patients, this gait training method is effective and suitable for stroke patients to increase the ability of functional performance.

Purpose: This study aimed to examine the effects of proprioceptive neuromuscular facilitation (PNF) upper and lower limb coordinated exercises on balance in elderly women. Methods: The study was conducted with 27 elderly women who were at least 65-year-old. The subjects were randomly assigned to a PNF upper and lower limb coordinated exercise group consisting of 14 subjects and an aero step balance exercise group consisting of 13 subjects, and the exercises were performed for 30 minutes, three times per week, for eight weeks. One Leg Stance Tests (OLST), Functional Reaching Tests (FRT), Four Square Step Tests (FSST), and Timed Up and Go (TUB) tests were conducted before and after the exercises to evaluate the subjects' static balance ability and dynamic balance ability. Among the collected data, the subjects' general characteristics were evaluated using descriptive statistics, the intra-group differences of the test results before and after the intervention were compared using paired sample t-tests, and the inter-group differences in the results before and after the intervention were evaluated using independent sample t-tests. The statistical significance level was set to 0.05. Results: Among the OLST, FRT, FSST, and TUG tests, the experimental group showed positive FSST results that were statistically significantly greater than the control group; the results of the other tests were also more positive for this group, but the differences between the groups were not statistically significant. The magnitude of the effects for both groups was clinically significant. Conclusion: Since inter-limb coordinated exercises for PNF applied to elderly women were found to produce good results for both static balance ability and dynamic balance ability, these exercises can be used in exercise programs to improve balance in elderly women.

The IMO has adopted emission standards that strictly restrict the use of bunker C oil for vessels. Accordingly, research and bunkering pilot projects for LNG fueled ships are being actively carried out, which is expected to substantially reduce environmental pollution. In this study, we have adopted the turret moored Floating LNG Bunkering Terminal (FLBT) designed to receive the LNG from LNGCs and to transfer LNG to LNG bunkering shuttles in ship to ship moored condition. Numerical simulations have been performed with a 1-year return period of wind, wave, and current. Damping values of numerical model were adjusted from the results of model tests to obtain accurate simulation results. The results confirm safe berthing operation during the 1-year return period of environmental condition. Safety depends on the direction of environment, with increasingly stable operation facilitated by the application of heading-control function of FLBT to avoid beam-sea conditions.

PURPOSE: The present study was conducted to investigate the effects of functional electrical stimulation gait training with rhythmic auditory stimulation on balance and gait ability in stroke patients. METHODS: In this blinded randomized controlled study, 26 stroke patients were assigned to either experimental group (n=13) consisting of 30 min of gait training 5 days per week for 4 weeks while performing functional electrical stimulation gait training with rhythmic auditory simulation, or a control group (n=13) performing the same gait training program, also consisting of 30 minutes 5 days a week and lasting for 4 weeks, but without functional electrical stimulation and rhythmic auditory stimulation. At baseline and after the 4 week intervention, balance was measured using the timed up and go test (TUG). Gait velocity was measured using the 10-meter walk test (10 MWT) and gait ability was assessed using the functional gait assessment (FGA). RESULTS: After the intervention, the experimental group showed statistically significant differences in gait velocity and ability (10 MWT, FGA) (p<.05). Between-group differences were statistically significant in gait velocity and ability (10 MWT, FGA) (p<.05). CONCLUSION: The findings suggest that functional electrical stimulation gait training with a rhythmic auditory stimulation gait training program may help improve gait ability in stroke patients.

The purpose of this study was to examine the meaning and essence of the life of elderly men living alone in public rental housing. Among the phenomenological study methods, the present study used the analysis method proposed by Giorgi(2009). The study participants included 10 elderly men living alone in public rental housing who were recruited through network sampling. The research data were collected through in-depth interviews conducted twice for each person. The results showed that living alone as an elderly man is likened to standing against cold wind out in the wilderness of the world, with living alone deemed a power game between life and death. For the participants, public rental housing is a fence that separates them from the world-the final station of a wandering life. For common people, public rental housing is a stable fence, but for the participants, it is the location of a double-edged solitary life out in the wilderness where the instincts for survival and death play a tug of war. Based on the study findings, the researcher discussed and provided suggestions for psychological housing stability, the disparagement of the elderly in mass media, and countermeasures against psychological isolation.

Objective: Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairment in social skills and communication with repetitive behaviors. Etiology is still unclear although it is thought to develop with interaction of genes and environmental factors. Oxytocin has extensive effects on intrauterine brain development. Vitamin D, affects neural development and differentiation and contributes to the regulation of around 900 genes including oxytocin receptor gene. In the present study, the contribution of D vitamin receptor and oxytocin receptor gene polymorphisms in the development of ASD in Turkish community was investigated. To our knowledge, this is the first study examining these two associated genes together in the literature. Methods: Eighty-five patients diagnosed with ASD according to DSM-5 who were referred to outpatient clinics of Child and Adolescent Psychiatry of Başkent University and Mersin University and 52 healthy, age and gender-matched controls were included in the present study. Vitamin D receptor gene rs731236 (Taq1), rs2228570 (Fok1), rs1544410 (Bsm1), rs7975232 (Apa1) polymorphisms and oxytocin receptor gene rs1042778 and rs2268493 polymorphisms were investigated using real time polymerase chain reaction method. Results: No significant difference between groups in terms of distribution of genotype and alleles in each of polymorphisms for these genes could be found. Conclusion: Knowledge of genes and polymorphisms associated with the development of ASD may be beneficial for early diagnosis and future treatment. Further studies with larger populations are required to demonstrate molecular pathways which may play part in the development of ASD in Turkey.

PURPOSE: This study was conducted to determine the effects of treadmill gait training with obstacle-crossing on the static and dynamic balance ability of patients with post stroke hemiplegia. METHODS: Twenty-one patients with post stroke hemiplegia were divided into three groups as: treadmill gait training with obstacle-crossing (TOG, n=7), treadmill gait training without obstacle-crossing (TGG, n=7) and a control (CON, n=7). TOG and TGG performed exercise for 20 minutes, three times a week for 8 weeks. Static balance ability (stability typical, ST; weight distribution index, WDI; fourier harmony index, FHI; and fall index, FI) and dynamic balance ability (berg balance scale, BBS and timed up and go test, TUG) were measured before and after 8 -weeks in each exercise group. Statistical analyses were conducted using two-way ANOVA with repeated measures, a paired t-test, and multiple comparisons according to Tukey's HSD. RESULTS: FHI and BBS were significantly increased at TOG (p<.01) and TGG (p<.05) after 8-weeks compared to before treadmill gait training with obstacle-crossing. FHI and BBS were significantly increased at TOG compared with CON and TGG (p<.05). CONCLUSION: Treadmill gait training with obstacle-crossing was more effective than that without obstacle-crossing to improve posture control and independent daily life performance of hemiplegia patients.

Purpose: The purpose of this study was to evaluate the effect of task-oriented exercise and abdominal muscle contraction using functional electrical stimulation (FES) on abdominal muscle thickness and balance of stroke patients. Methods: Ten stroke patients who met the selection criteria were assigned randomly into two groups of five. One group received FES therapy before task-oriented training (experimental group), while the other group received a FES placebo before task-oriented training (control group). The Mann-Whitney U test was used to compare the groups, and the Wilcoxon Signed-ranks test was used to compare differences between the groups before and after intervention. The Mann-Whitney U test was used to compare the rate changes of each item before and after intervention, between the two groups. Results: In the rectus abdominalis and external oblique muscle thickness tests that used ultrasound, there was a statistically significant difference in the experimental group (p<.05),but no significant difference in the control group (p>.05). There was also a significant difference between the groups (p<.05). In the Balance test that used the Berg Balance Scale (BBS) and timed up and go test (TUG), there was a statistically significant difference in the experimental and control groups (p<.05), but there was no significant difference between the groups (p>.05). Conclusions: FES therapy before task-oriented training increases the thickness of abdominal muscles and improves balance abilities.
