  • Habitual speaking fundamental frequency (sF0) plays an important role in determining the voice classification, which can be presented differently depending on the vocal fold length and language habits. The purpose of this study, therefore, was to compare the differences in sF0 for voice classification and closed quotient between speaking and singing. Seventeen singers (7 sopranos, 5 tenors, 5 baritones, mean age 25.1 years) with no evidence of vocal folds pathology were participated. sF0 and closed quotient (CQ) both in speaking and in singing (A3-A5 with soprano, A2-A4 with tenor and baritone) were measured using SPEAD program and electroglottography. No significant differences were observed for sF0 between tenor and baritone groups (p> 0.05). However, CQ in singing was significantly different among three groups (p< 0.05), but CQ in speaking was not (p> 0.05). Furthermore, CQ was significantly different with both soprano (p< 0.01) and tenor groups ((P= 0.02) whereas baritone group revealed there is no difference when compared between speaking and singing. No significant differences in sF0 between tenor and baritone participants may result from decision-making for voice classification by experience and should measure sF0 before determining the voice classification.

  • Purpose : We aimed to investigate the effect of cranio-cervical flexion exercises(CCFE) with visual feedback(VF) on the muscle activity of the upper trapezius in forward head posture (FHP) and whether deficits in proprioception affect the changes in muscle activity. Methods : Twenty subjects with FHP were assigned to one of 2 groups according to deficits in proprioception. The muscle activity of the upper trapezius during arm movement under three exercise conditions (resting, CCFE, and VF + CCFE). Repeated-measures analysis of variance was used to compare differences in muscle activity according to the exercise conditions between the groups and to analyze the interactions between groups and conditions. Results : Significant differences were observed in muscle activity according to the exercise condition (p<.05), with no significant differences between the groups. The muscle activity of the upper trapezius was significantly different between the resting and VF +CCFE conditions (p<.05), with no significant difference between the resting and CCFE conditions (p>.05). Conclusion : The results of this study showed that the CCFE combined with VF are an effective intervention for FHP to train deep muscles selectively. In addition, the loss of proprioceptive sensation is not related to changes in muscle activity during exercises.

  • Purpose: Owing to increased life expectancy, the number of elderly patients with gastric cancer has increased. This study aimed to identify the outcomes of gastric cancer patients aged 80 years or older through comparison of their clinicopathological characteristics, surgical outcomes, and oncologic outcomes. Materials and Methods: Between January 2006 and December 2013, the records of 478 patients who underwent surgery for gastric cancer were retrospectively evaluated. Patients were divided into two groups: patients <80 years old (n=446) and patients ${\geq}80$ years old (n=32). Results: There were no significant differences in sex, body mass index, length of hospital stay, duration of surgery, depth of invasion, nodal metastasis, histologic type, or tumor size between the two groups. However, significant differences were found for the American Society of Anesthesiologist score and the serum albumin level between the two groups. Postoperative morbidity, mortality, disease-free survival, and recurrence rate did not differ between curatively resected patients in the two groups. Conclusions: In elderly patients with gastric cancer, active treatment including radical gastrectomy is necessary.

  • PURPOSE: In adults with hamstring tightness, stretching is considered a therapeutic exercise that improves flexibility. However, previous studies have reported efficacy of numerous methods, and are inconclusive in determining the most effective stretching techniques. This study aims to compare the outcomes of Evjenth-Hamberg stretching (E-HS), proprioceptive neuromuscular facilitation stretching (PNFS), and static stretching (SS), on muscle tone and flexibility. METHODS: A total of 30 subjects were assigned to each of the three stretching groups:; E-HS (n1 = 10), PNFS (n2 = 10), and SS (n3 = 10). Muscle tone of the hamstring muscle, active knee extension (AKE), and passive knee extension (PKE) were assessed by range of motion. RESULTS: After the intervention, statistically significant differences were obtained between groups for muscle tone (p < .05). The post hoc test, showed statistically significant differences in muscle tone between the E-HS and PNFS groups (p < .05), and PNFS and SS groups (p < .05). Post hoc test after intervention, also revealed statistically significant differences in flexibility (p < .05) between the E-HS and PNFS groups (p < .05), E-HS and SS groups (p < .05), and PNFS and SS groups (p < .05). Moreover, a statistically significant difference was observed in PKE scores between the E-HS and SS groups (p < .05), and PNFS and SS groups (p < .05). CONCLUSION: This study indicates that E-HS may be the most effective stretching technique for muscle tone and flexibility, in adults with hamstring tightness.

  • 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.
