The normal aging process on speech production and these changes are perceived by listeners. This study examined whether age perception changed under various conditions of prosodic manipulations in normal listeners, comparing the prosodic changes according to age and sex in adulthood. The older and younger voices were resynthesized by manipulation of the speaking rate and pitch to shift the perceived age of the groups toward each other. Two-way repeated ANOVA were conducted to determine if the prosodic type of resynthesized cue resulted in a significant shift in perceived age of young and old voices. The manipulation of the speaking rate resulted in a significant shift in perceived age for the older and younger groups. A significant shift in age estimates was not observed for the younger male group when pitch was manipulated. There were significant gender-by-age group interactions for prosodic manipulation type. Age-related changes in the prosodic properties of speech may ultimately influence speech perception.

Purpose: The purpose of this study is to identify risk factors of accidental falls by age in the Korean elderly. Methods: The study subjects included 10,242 community-dwelling elders aged 65 or over. The data were analyzed by logistic regression analysis. Results: The risk factors of accidental falls in the younger old group (aged 65~74) include fear of falling (OR=16.28, 95% CI: 12.03~22.03), depression (OR=1.24, 95% CI: 1.06~1.44), and hearing impairment (OR=1.20, 95% CI: 1.01~1.43). The risk factors of accidental falls in the older old group (aged 75~84) include fear of falling (OR=11.54, 95% CI: 7.04~18.93), muscle strength (OR=1.36, 95% CI: 1.15~1.60), number of chronic disease (OR=1.65, 95% CI: 1.09~2.50), and presence of spouse (OR=1.27, 95% CI: 1.06~1.51). The risk factors of accidental falls in the oldest old group (aged 85 years old or older) include fear of falling (OR=8.05, 95% CI: 1.85~34.98) and exercise (OR=2.91, 95% CI: 1.36~6.24). Fear of falling is defined as a common factor in the all age groups. Conclusion: Different strategies should be developed for age groups to prevent elderly falls with understanding of contributing factors of falls in each group.

In order to evaluate acute toxicity of Coptidis rhizoma, 6 week- and 13 week-old male ICR mice received Coptidis rhizoma extract (600~4,800 mg/kg body weight) orally, and toxicological responses were observed for consecutive 7 days. In the mice received relatively high concentration of Coptidis rhizoma($\geq$1,200mg/kg), death occurred within 3 hrs after oral administration, and its ratio in 13 week-old mice was conspicuously higher than that in 6 week-old mice. $LD_{50}$ of Coptidis rhizoma were estimated to bi 2,575 mg/kg and 1,490 mg/kg body weight in 6 week and 13 week-old mice, respectively. Coptidis rhizoma-treated animals manifested a variety of abnormal clinical findings such as ptosis, crouching, lethargy, convulsion, bizarre behavior and truning sideway. These abnormalities also ranked highly in the 13 week-old mice compared to those in the 6 week-old mice. In addition to abnormal behaviors, Coptidis rhizoma($\geq$1,200 mg/Kg) significantly elevated the urinary contents of bilirubin, urobilirubin, protein and glucose, and values in 13 week-old mice was higher than those in 6 week-old animals. No toxicological response was observed at concentration less than 600 mg/kg. Our results clearly demonstrate that susceptibility of mice to Coptidis rhizoma may be related with age, indicating that younger age mice is more resistant to the Coptidis rhizoma than the older, and toxicological mechanism of Coptidis rhizoma may be closely associated with its pharmacological mechanism.

The lung cancer in patients under 40 years old is rare and reported to be more rapidly fatal than in older persons. We reviewed the records of 18 cases who younger than 40 years with histologically proven lung cancer between 1959 and 1992 at department of Thoracic Surgery in National Medical Center. There were 12 male and 6 female patients. Two male and all female patients had never smoked. The 17 cases had respiratory symptoms for a mean duration of 3 months. The squamous carcinoma was found in 7 cases[38.9%], small cell carcinoma in 4 cases[22.2%], mixed cell carcinoma in 4 cases[22.2%], adenocarcinoma in 2 cases[11.1%] and bronchoalveolar cell carcinoma in 1 case. Among the 6 resected tumors, one case was stage I, two cases were stage II and three cases were stage IIIa. The operation was considered complete and curative in 6 patients and noncurative in 6 pations because of an exploratory thoracotomy. We conclude that lung cancer in young persons is virulent and that diagnosis is frequently delayed.

A laboratory study was conducted to evaluate if two different age groups(young vs. old) had differences in walking velocity and heel contact velocity and, furthermore, if these gait characteristics could adversely influence initial friction demand characteristics(i.e. RCOF) and the likelihood of slip-initiation. Twenty eight(14 younger and 14 older adults) participated in the study. While wearing a safety harness, all participants walked at their preferred gait speed for approximately 20 minutes on the linear walking track(1.5m× 20m) consisting of two floor-mounted forced plates. During subsequent 20 cameras, respectively. The results indicated that older adults walked slower(i.e., slower whole body center-of-mass velocity), exhibited lower heel contact velocity, and produced lower initial friction demand characteristics (i.e. RCOF) in comparison to younger adults. However, ANCOVA indicated that the diferences in heel contact velocity between the two age groups were due to the effects of walking velocity. The bivariate analysis further suggested that walking velocity was correlated to RCOF and heel contact velocity, while heel contact velocity was not found to be correlated to RCOF. In conclusion, could be a better indicator for predicting initial friction demand characteristics(i.e. RCOF) not hel contact velocity.

In this study of age differences in the correct judgment of relative size and size comparison strategies, 114 three-, four-, and five-year-old children were asked to judge the relative size of 2 figures. Findings were that older children judged size comparison more correctly than younger children. The 5-year-old children used the strategy of superimposition more frequently than younger children, though children in all age groups most frequently used the strategy of one sided comparison with one side of each figure touching the other. The strategy in which one figure is put on top another with a general shape adjustment led most frequently to correct judgment of the relative size of 2 figures.

Diagnostic and therapeutic strategies of prostate cancer may largely influenced by patients' age at presentation. This study is aimed to evaluate the characteristics, diagnostic and treatment strategies in prostate cancer patients in our centres. A cross-sectional analytic study of prostate cancer data in two main referral cancer centres, Cipto Mangunkusumo General Hospital and Dharmais National Cancer Centre from 1995-2010, was therefore performed. Patients were divided into 2 sub-populations; below 60 years (younger patients) and 75 years old and above (older patients). PSA levels, diagnostic modalities, Gleason score and therapeutic options were analysed for both and compared using bivariate analysis. 152 patients were <60 years and 210 were ${\geq}75$ years. There was no statistical difference in mean PSA level (797.9ng/mL vs 345.3 ng/mL, respectively; p>0.05) and diagnosis was made by biopsy in majority of patients in both groups (68.2% and 71.6% in younger and older groups respectively). Most presented with an advanced disease stage (65.1% and 66.0%, respectively) and there was no statistically significant difference in mean Gleason scores f (8.1 vs 7.7; p>0.05). Primary androgen deprivation therapy (PADT) was the main treatment for overall patients (48.0% and 50.7%, respectively). Radiotherapy and radical prostatectomy are the main therapeutic modalities for younger patients with local and locally advanced disease (39.6% and 35.4% respectively), while the majority of older patients with the same disease stage were treated with radiotherapy and PADT (45.8% and 39.0% respectively). Differences observed in treatment modalities were statistically significant (p<0.0003). We conclude that there is no difference in disease clinical aggressiveness of the two groups but significant differences were observed in therapeutic strategies utilised with younger and older patients.

This study investigated the recognition and preference of a chicken menu according to the age of adults in the Jeonbuk area. Self-administered questionnaires were collected from 394 adults (male 55.3%, female 44.7%) residing in the Jeonbuk area. Descriptive and comparative statistical data analysis was completed using SPSS v. 12.0. The frequency of consumption of chicken-containing foods for the younger group (20~30 years old) was significantly higher than the frequency of older groups (over 40) (p<0.001). The younger group also consumed chicken food through a delivery service, whereas the older group consumed chicken through delivery and self-cooking. Approximately 50.0% of the older group preferred the chicken leg whereas 38.1% of the younger group preferred the chicken breast (p<0.001). The most highly recognized chicken menu items, among 36 chicken menus, were Samgyetang (2.93), chicken dori-tang (2.93), and fried chicken (2.93). The older group knew about a chicken menu made by traditional cooking much more than the younger group. The most highly preferred chicken menu item was spicy fried chicken (4.18). The preference for Western-style chicken menu (e.g. Cajun chicken salad, chicken sandwich) was significantly higher in the younger group than the older group (p<0.001, p<0.05). Therefore, to develop a new chicken menu, the consideration of favorite chicken parts and an age-based menu is necessary.

Background: To evaluate pathological features of head and neck squamous cell carcinoma (HNSCC) and to compare these pathological features in patients younger and older than 40 years. Materials and Methods: All resection specimens of HNSCC between 2010 and 2013 evaluated. Tumor characteristics - grade, location (site) cervical node status, alongwith presence or absence of extranodal extension, lymphovascular invasion, gender and age - were extracted from surgical pathology reports. Results: Among these n=19 patients (21.8%) were 40 years or younger and n=68 patients (78.2%) were above 40 years of age. The mean age was 34 (20-40 years) in the younger group and 56 (42-86) in the older group. The most common location of HNSCC in both groups was the oral cavity. The analysis of histopathological features including grade of tumor, tumor size, extranodal extension and comparison between two groups do not show any significant difference. Conclusions: There are no specific pathological characteristics of HNSCC in young patients. An interesting observation is that exposure to expected risk factors is similar in both groups, in younger patients they have less time to act and yet tumors are the same in terms of tumor size, lymph node status and lymphovascular invasion. Therefore further research is recommended to look for potentiating factors.
