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.

This study aimed to identify the development pattern of final stop consonant perception using the gating task. Sixty-four subjects participated in the study: 16 children aged 4 years, 16 children aged 5 years, 17 children aged 6 years, and 15 adults. One-syllable words with consonant-vowel-consonant(CVC) structure, mokㄱ-motㄱ and papㄱ-patㄱ were used as stimuli in order to remove the redundancy of acoustic cues in stimulus words, 40ms-length (-40ms) and 60ms-length (-60ms) from the entire duration of the final consonant were deleted. Three conditions (the whole word segment, -40ms, -60ms) were used for this speech perception experiment. 48 tokens (4 stimuli ${\times}3$ conditions ${\times}4$ trials) in total were provided for participants. The results indicated that 5 and 6 year olds showed final consonant perception similar to adults in stimuli, papㄱ-patㄱ and only the 6-year-old children showed perception similar to adults in stimuli, 'mokㄱ-motㄱ. The results suggested that younger typically developing children require more acoustic information to accurately perceive final consonants than older children and adults. Final consonant perception ability may become adult-like around 6 years old. The study provides fundamental data on the development pattern of speech perception in normal developing children, which can be used to compare to those of children with communication disorders.

Objectives: The purpose of this study is to identify the relationship between metabolic syndrome factor diseases and falls in the elderly aged 65 years or older and use them as basic data to reduce the risk of falls. Methods: The method of this study was to compare the injury-related characteristics of the fall and non-fall groups with a factor disease of metabolic syndrome in Korea over 65 years of age. Data from the 14th National Hospital Discharge In-depth Injury Survey in 2018 were used to conduct the study. A total of 7,991 data were analyzed using SPSS 23.0. Results: Among the total injuries, the fall group with metabolic syndrome factor disease accounted for 69.0% and the non-fall group 31.0%. Falls occurred in 86.3% of households. In the fall group with metabolic syndrome factor disease, the number of females was 1.9~2.1 times higher than that of males. Compared to 65~69 years of age, the incidence of falls was 1.4~1.5 times higher in 70~79 years, 1.7~2.2 times higher in 80~89 years, and 2.5~3.6 times higher in 90-year-olds and older. In NISS, the incidence of falls was 1.7 times higher in moderate compared to mild. In principle diagnosis, the incidence of falls was 2.2 times higher in S40-S99 compared to S00-S19. Conclusion: The elderly with metabolic syndrome factor disease should continue to promote health through light exercise that can strengthen muscle strength to prevent falls.

Background: Growing evidence suggests that beta-hydroxy-beta-methylbutyrate (HMB), arginine (Arg), and glutamine (Gln) positively affect wound recovery. This study investigated the effects of long-term administration of HMB/Arg/Gln on pressure ulcer (PU) healing in sedentary older adults admitted to geriatric and rehabilitation care facilities. Methods: This was a pilot retrospective case (standard of care and HMB/Arg/Gln)-control (standard of care alone) clinical study. Outcome measures were relative healing rates and Pressure Ulcer Scale for Healing (PUSH) scores (calculated after 4, 8, 12, 16, and 20 weeks) and time to healing. Results: The study subpopulation was comprised of 14 participants (four males, 28.6%) with the median age of 85.5 years (interquartile range [IQR], 82.0-90.2 years). The control subpopulation was comprised of 31 participants (18 males, 58.1%) with the median age of 84.0 years (IQR, 78.0-90.0 years). At the beginning of follow-up, there were no statistically significant demographic (sex and age) and clinical (main diagnosis, baseline area, and PU perimeter) differences between the groups. During the study period, there were no significant differences in the relative healing rates and PUSH scores between the subpopulations. The median time to complete healing in the study and control populations was 170.0 days (95% confidence interval [CI], 85.7-254.3) and 218.0 days (95% CI, 149.2- 286.7) (log-rank, chi-square=3.99; p<0.046), respectively. Conclusion: More than 20 weeks of HMB/Arg/Gln supplementation had a positive effect on difficult PU healing in older adults with multiple comorbidities.

Food/nutrition related views, beliefs, attitudes, and behaviors were investigated for three hundred randomly selected men and women, aged 20-60 years, residing in Seoul metropolitan area. Food/nutrition views, attitudes, and beliefs were found to vary greatly between groups of different age, sex, education and income level. Adults of 20-35 years of age showed significantly less strong views about keeping traditional food habits, while exhibiting a significantly high level of acceptance towards the use of convenience foods as compared to the adults aged 36 years or older. Food safety was found to be a major concern to most of the subjects accounting 69.7% for pesticides residues in fresh produce items, 94.7% for food additives in processed food, and 56.3% for food poisoning in foods eaten outside of the home. Male adults aged 45 years or older showed a strong tendency to rely on a few promotional food products for the maintenance of their health and for them the development and implementation of a sensible feed nutritin/health education program including a way to avoid nutrition quackery might be beneficial. Eighty percent of the subjects were found to read food labels with higher rates shown among young adults and females. Due to the virtual absence of nutrition labeling however, the percentage of subjects who idicated that they are looking for the information on nutrient content was low (<10%) compared to the rates for other informations such as date of manufacture(80.2%), expiration data(55.8%), ingredients(40.9), and additives(40.9%). Ninety one percent of the subjects indicated that they would like to see the sources for nutrition label the nutritional value of the foods. The top five most frequently (68.3%), food packages(50.7%), and radio(43.3%). Health professionals such as physicians, nurses, and nutritionists/dietitians were utilized less frequently as sources of nutrition information than lay sources, with reported rate of only 38%, 22%, and 0.7%, respectively. These results collectively suggest that strategies are to be developed to provide accurate nutrition information to adults.

Although there are many old school buildings that is more than 40 years in Korea, it is difficult to rebuild all of them due to limitations in budget management. Therefore, objective feasibility evaluation criteria are necessary to determine which school buildings should be rebuilt preferentially among the numerous old school buildings. One of the rebuilding feasibility evaluation items, economic evaluation generally requires documents such as construction statements and facility drawings. However, because most buildings older than 40 years do not have these documents, an economic analysis model that requires only basic building information should be developed. In this study, the economic analysis model that can be used for evaluating the rebuilding feasibility only with the number of years, total floor area, and structural information of school buildings was established. This model can contribute to the objective feasibility evaluation of old school buildings because it can evaluate numerous buildings on the same criteria based on basic building information.

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.

Objective: To compare the mammogarphic appearance between breast cancer patients aged <40 and ${\geq}40$ years. Methods: Needle localization and biopsy of suspicious mammographic lesions identified 1,959 breast carcinomas in a single institution from Jun 2012 to Apr 2013. According to the age, we divided patients into two groups: <40 and ${\geq}40$ years old, and analyzed mammographic appearance separately. Results: Young patients had 44.2% foci with calcification, but old patients only had 39.4% (P<0.001). In younger group, the ratios of cases according to mass density were 41.8% or higher, 58.2% equivalent and lower. In older group, the ratios were 55.5 % and 44.5%, respectively. There were statistical differences between high density and others (P<0.05). The ratios of cases according to mass margin were 13.9% circumscribed and microlobulated, 86.1% indistinct and spiculated in the younger group, as compared to 6.5% and 93.5%, respectively, in the older group (P<0.05). Conclusions: Mammographic findings differ between young and old patients with breast cancer, for example regarding mass density, mass margin and microcalcification ratios.

This study was carried out to investigate the perception, preference and usage of Korean festival foods of women according to age in Busan. The survey was conducted from October 15, 2012 to November 30, 2012 using questionnaires and the data were analyzed with the SPSS program. In general, younger women (20~30 years old) had a lower interest in Korean festival foods than slightly older women (40~50 years old). Most of women over 40 years of age prepared Korean festival foods at home, but many who were in their 20's (45.9%) and 30's (41.1%) obtained their foods from family and relatives. Overall, 62.5% of the subjects wanted to inherit Korean festival food from family and relatives. The dissemination of information and recipes of Korean festival foods were needed for succeeding to Korean festival foods. The taste score was significantly lower for women in their 20's compared to those over 40. Women under 40 reported a lower ease of cooking compared to women over 50. Tangguk (4.93) on Seollal showed the highest perception degree in the order of Namul (4.91), Tteokguk (4.90), and Sikhye (4.90). Jeon, Yaksik, Sikhye, and Gangjeong were the most highly preferred in every group. The preference degree of Pajeon was significantly higher in women under 40 than in those over 60. Tteokguk and Tangguk were more highly preferred in women in their 30's and 40's compared to the other groups. There was a significant positive correlation between preference for festival food and education level, degree of knowledge, degree of interest, will for inheritance, and will for learning (P<0.01). In conclusion, festival foods rich in local tradition should be developed, publicized and used to educate others. The simplification of cooking methods and the development of processed foods are needed to pass on the traditional food culture of Busan.

Purpose: This study aimed to investigate the association of social participation and depressive symptoms with health-related quality of life (HRQoL) among older adults living in urban and rural areas. Methods: This secondary, cross-sectional study was conducted with a total of 66,765 adults aged ≥65 years (urban-26,485 and rural-40,280) who participated in the household and individual surveys of the Korea Community Health Survey 2019. Data on the main study variables including social participation, depressive symptoms, and HRQoL were collected from August 16 to October 31, 2019. Multiple linear regression was used to identify the factors affecting HRQoL in urban and rural older adults. Results: The proportion of social participation (χ²=354.69, p<.001) and the level of HRQoL (χ²=12.06, p<.001) were significantly higher in older adults living in urban area than those in rural area. However, there was no significant difference in depressive symptoms between older adults living in urban and rural areas. Multiple linear regression analysis showed that social participation and depressive symptoms were significant predictors of HRQoL in both urban and rural older adults. Conclusion: Our main finding highlights that active participation in social activities and management of depressive symptoms in older adults regardless of living arrangements are crucial to improve HRQoL in later life. Interventions to increase social participation include early assessment of depressive symptoms in the community to promote HRQoL. More longitudinal studies are needed to identify the factors associated with HRQoL between older adults living in urban and rural areas while considering neighborhood environment and living arrangements.
