This study analyzed data from the Korea National Hospital Discharge In-depth Injury Survey (KNHDIS) (2004~2021) and found that for the young-old with disabilities, the location of injury was roads and main roads, the activity at the time of injury was daily life, the mechanism of injury was falling and the type of transportation accident was collision with passenger cars. In the old-old, the characteristics by type of injury were fractures, the intentionality of the injury was unintentional, the place of injury was residence, the activity at the time of injury was daily life, the mechanism of injury was falling and the type of transportation accident was pedestrian. In conclusion, the old-old were more likely to suffer injuries at home and in daily life than the young-old with disabilities, and old-old injured patients were more active than the old-old, resulting in higher falls and transportation accidents and older seniors were more likely to have pedestrian accidents. Based on the information collected from the young-old and old-old, it is believed that efforts to prevent damage that consider the characteristics of the elderly are necessary.

Using data from the 2015 Korea Welfare Panel Study, we examined the predictors of psychological well-being (life satisfaction and depression) of single elderly people living alone across development stages (young-old, mid-old, and old-old) and suggested implications for elderly policy. For this purpose, we selected 1,364 elderly people who lived alone but preserved their family relationships, and were 65 years of age or older. Separate analyses were conducted for the three groups of single elderly people living alone. Overall, the psychological well-being of single elderly people living alone was higher than moderate level, and they were generally satisfied with their everyday lives and less depressed. However, there were group differences: the young-old group was more satisfied than the old-old group with in their everyday lives and less depressed than the mid-old and old-old groups. In the young-old group, life satisfaction was significantly associated with subjective health, non-physical conflict with family, disposal income, house ownership, dietary deficiency, cost of living, and public pension. In addition, depression was significantly associated with subjective health, non-physical conflict with family, dietary deficiency, and physical conflict with family. In the mid-old group, life satisfaction was significantly associated with subjective health, housing non-physical conflict with family, disposal income, and dietary deficiency. Depression was significantly associated with subjective health, housing deficiency. In the old-old group, life satisfaction was significantly associated with subjective health and non-physical conflict with family. Depression was significantly associated with subjective health. Therefore, 'health'and 'family'are important key concepts to consider when making elderly policy.

In order to check ordinary trend of a research for old ages, it was collected and analyzed against old ages. Out of a research papers from 1995 to 2005 issued for 6 scientific journals in clothing and textiles areas which were listed on KOREA RESEARCH FOUNDATION. The results were as follows. First, the research papers for 11 years from surveyed scientific journals were totally 5,711 papers, and It were only 71 papers for old ages to be reviewed and surveyed, which slightly occupied 1.24% from whole papers. Second, yearly ranges of research paper against old ages were shown to be down-trend, as it recorded 2.75% in 1995, however it falls on 0.77% in terms of the increasing aspect of clothing and textiles research paper numbers. Third, a paper for each research areas ranged in turn, as clothing construction, fashion merchandising socio-psychology of clothing, etc. If we see in detail area, the research for somatotype and role occupied 37.4% from all researches against old ages. Accordingly it needs more various kinds of study. Fourth, The Koreav Society of Clothing and Textiles paper occupied 40.8% from whole scientific journals, which was obviously shown. Fifth, each sex distribution for researched old ages noted almost old women (77.5%), but cover 9.9% for old men. Therefore it required much more researches for old men, we thought.

Wild Korean ginseng has been recognized as highly precious medicine since ancient times. Nowadays, the population of wild ginseng in the forest of Korean peninsula is very rare due to indiscreet harvest. In this work, we investigated the plant regeneration via somatic embryogenesis from embryogenic callus of old wild ginseng (more than 50 years-old) and compared the features of plants regenerated from 5-years old and 50 years-old ginseng. Induction of embryogenic callus from adventitious roots of 50 year-old wild ginseng required 83 weeks of culture, but only 10 weeks were sufficient for 5 year-old ginseng. Height and width of plants derived from the old wild ginseng was smaller and slender compared to the plantlets derived from 5 year-old ginseng. Total chlorophyll contents was 2-6 time lower in plantlets regenerated from 50 year-old wild ginseng than those from 5 year-old ginseng, but anthocyanin content was higher in 50 year-old ginseng. Our results revealed that plants regenerated from old wild ginseng have different morphological and physiological characters probably due to age-dependent phenomenon.

Purpose: The purpose of this study was to investigate the level of life satisfaction and the significant factors which impact on life satisfaction of young-old (60-69 yr), old (70-79 yr), and oldest-old (80 yr or above) women. Methods: The participants for this study were 289 elderly Korean women living in the city of Daegu and Kyongpook province. The data were collected using structured questionnaires. ANOVA, Chi-square, and multiple regression with the SPSS program were used to analyze the data. Results: There were statistically significant differences among young-old, old, and oldest-old women regarding the existence of spouse, income, educational status, and religions. The model including variables related to physical, psychological, financial, and social aspects of life, explained variance of life satisfaction of elderly women differently, such as 55% of young-old, 37% of old, and 66% of oldest-old. Finally, self-esteem was the only predictor in explaining the level of life satisfaction among old women regardless age. Conclusion: Based on the findings of the study, implications for practical services for elderly women and recommendations of further study are provided. Nursing interventions should be developed to improve life satisfaction of elderly women according to age differences.

We analyse the map of the west capital Pyongyangbu of Old Korea(AD 920) by topological method and geometrical method and compare it with the map of North Korea Pyongyang. By the analyse of the map we find the real place of the old map. The analysing and finding the real place of the old map is a very good example of geometry education. Many Koreans had learned and recognized that Old Korea(AD 920) was a small country located in the south part of Ablok river. But, after reading this paper they change their old recognitions and they take prides in Great Old Korea.

Starch was isolated from 4-year-old and 6-year-old ginseng roots and its physical and chemical characteristics were studied. The results obtained were summarized as follows. 1. The shape of ginseng starch granules was polygonal and rounded with its granule size ranging from 2.0 to 7.5$\mu$. The swelling power of 4-year-old ginseng starch was much greater than that of 6-year old ginseng starch. Gelatinization pattern showed that 6-year-old ginseng starch gelatinized rapidly at $65^{\circ}C$, whereas 4-year-old starch continued to gelatinize, without having a definite gelatinization temperature as temperature increased 3. Amylogram of ginseng starch showed that gelatinization initiated at 61$^{\circ}C$ and was completed at 88$^{\circ}C$ with its viscosity reaching at 810 B.U. 4. The amylose contents were 32% and 9% for 4-year-old and 6-year-old ginseng starch, respectively. 5. X-ray diffraction analyses indicated that there were some structural differences between 4-year-old and 6-year-old ginseng starch.

Purpose: The purpose of this study was to investigate the prevalence of depression and its' correlates among elderly people(young-old vs old-old) with poverty. Methods: The sample was 434 of young-old elderly and 209 of old-old elderly people who were 60 and over and basic livelihood recipient in Korean urban community. Depression was measured by Geriatric Depression Scale by Yesavage et al.(1983) in Korean Version. Results: The prevalence of depression was greater for old-old people(63.2%) compared to young-old people(53.9%). Multivariate logistic regression analysis shows the difference of correlates of depression between young-old and old-old elderly people. Prevalence of depression in young-old people was associated with renting in housing type; bad self-rated health status; lack of regular leisure activity; lack of regular eating habit, whereas old-old people was affected by lower social support; moderate or bad self-rated health status; lack of regular leisure activity Conclusion: The finding of differences in prevalence of depression and its' correlates between young-old and old-old people is expected to promote the screening strategy for elderly at risk of depression in Korean community elderly with poverty.

This study investigated the prevalence of unmet needs for health care among Korean adults and related factors. Using data from the 2012 Korea Health Panel, 1,896 adults aged 65 and over and two age groups(Young-Old(66-74) and Old-Old($65{\leq}$)) were analyzed to identify these factors. Logistic regression analysis was used to examine the main factors associated with unmet medical needs. According to the results of this study, the factors influencing unmet medical needs with regard to economic factors were Subjective Health Status(young-old), Disability(young-old), Activity Limitation(young-old), Education Level(old) and Economic Activity(old). The factors influencing unmet medical needs were factors of attitude, information, and disease. factors were Disability(young-old), Activity Limitation(young-old), Education Level(old) and Economic Activity(old). Therefore, further research that investigates unmet needs depending on age group in the elderly would suggest helpful policy implications.

Purpose: The purpose of this study was to identify the influence of physical activity and depression on sleep quality among the young-old and old-old community-dwelling elderly. Methods: Participants were 216 community-dwelling older adults in Korea aged 65 or above. Data were collected using structured questionnaires with face-to-face interviews that included demographic and health-related characteristics, International Physical Activity Questionnaires (IPAQ), the Short Form Geriatric Depression Scale (SGDS) and the Pittsburgh Sleep Quality Index (PSQI). A hierarchical multiple regression was conducted to examine whether physical activity and depression would predict sleep quality under other controlled factors. Results: There were differences in demographic and health-related characteristics, physical activity, and depression by age groups, but not in sleep quality. In the young-old elderly, physical activity (${\beta}=-0.22$, p=.043) and depression (${\beta}=0.31$, p=.002) were significantly associated with sleep quality (F=4.46, p=.001, Adjusted $R^2=.16$). In the old-old elderly, physical activity (${\beta}=-0.29$, p=.001) and depression (${\beta}=0.41$, p<.001) were significantly associated with sleep quality (F=10.79, p<.001, Adjusted $R^2=.29$). Conclusion: These finding highlight physical activity and depression as important contributors to sleep quality in both young-old and old-old elderly.
