Currently, Hyphantira cunea Drury, the fall webworms (FWW), is one of the most severe insect pest for various landscaping trees and mulberry trees. In this study, we investigated whether FWW might be managed by Sodium saccharin (SAC) which is a food additive and not toxic to humans and environment. We found that FWW larvae treated with various concentrations of SAC showed dose-dependent delayed development and low survival rates. The lethal-concentration 50% of FWW larvae to SAC was 0.03 M. We also confirmed that SAC can be used to control FWW larvae attacking mulberry trees in the field. Compared to not-treated or tap-water-spraying control groups, SAC-spraying groups showed significantly higher mortality rates of FWW larvae (56.2%). Thus, SAC can be used for control FWW larvae in mulberry trees.

Purpose: The aim of this study was to describe problems and solutions for older adults living alone and using wearable devices to report depressive moods in daily life. In addition, gerontology nurses' competencies and strategies were discussed based on lessons learned from the observational study. Methods: A hybrid method was used, combining literature review and content analyses based on interviews with 53 participants and observations done by the research team. Results: Main issues and relevant strategies were identified in terms of (1) applicability of information and communications technology (ICT) devices for older adults, (2) feasibility of older adults' use of ICT devices, (3) integration of ICT devices into daily life, and (4) relevant issues when older adults use ICT. Important roles and competencies were discussed regarding general and gerontology aspects of ICT. Conclusion: Findings indicate that a wearable device is feasible to measure daily depressive moods in older adults living alone in community settings. To extend our research protocol to practice, gerontology nurses must adequately prepare to meet emerging health care trends and end users' needs for ICT-based nursing. It is necessary to develop diverse educational programs and active involvement in research and design of relevant devices and programs.

This study analyzed the 2019 Community Health Survey data to compare and analyze the health levels and life satisfaction of single-person elderly households based on food security. The final study subjects were 15,606 single-person elderly individuals aged 65 and above. These subjects were classified based on their response to food security into three groups: food sufficient-diverse, food sufficient-not diverse, and food insufficient. The study results showed that the proportion of the food insufficient group among single-person elderly households was 7.4% for men and 10.6% for women, with a slightly higher rate for female elderly. Both male and female elderly over 80 years of age, with low education levels, and basic living support recipients showed significantly higher proportions in the sufficient-not diverse and food insufficient groups. For male elderly, significant differences were observed in subjective health status and oral health level in the food insufficient group, and for female elderly, stress levels also showed significant differences. Life satisfaction scores were generally lower for female elderly compared to male, and significant differences were found in both male and female elderly based on food security. Common factors that significantly influence life satisfaction among single-person elderly households, both male and female, include food security, subjective health status, and living environment satisfaction, with food security being the most impactful factor. The study suggests that it is necessary to include these significant factors in the development of various social activity programs, such as dietary programs, to enhance life satisfaction and food security of single-person elderly households.

On the basis of the widely collected fork prescriptions, long clinical practice of himself, together with integration of all the good points of earlier medical specialists, 孫思邈 wrote 『千金方』 of thirty volumes. Among them Volumes 『食治』 (Food Therapy) and 『養性』(Cultivating the Character) are especially meaningful for in gerontology. Thirty years after its completion, as a supplement, he wrote another thirty volumes of 『千金翼方』. Mr. Sun integrated his discoveries in the treatments of the aged patients, and his opinions for longevity into the Volumes 『養性』 (Cultivating the Character), 『?穀』(Fasting), 『退居』(Retirement), 『補益』(Supplementation). Thus he laid down the basic foundation for the gerontology of Chinese medicine. 『千金要方』 and 『千金翼方』 by Mr. Sun discuss mainly the prevention of illness for aged patients. As for the function of food therapy, he explains: 'Food can dispel evil elements of the body and settle down its organs. It can further bring pleasure to man's spirit and help the circulation of blood and breath.' He then propose the major method of food therapy: 'For a medical doctor, he should understand the causes of disease, then treat it with food. Only after the food treatment fails, medicine is employed.' He thinks that medicine does work in treatment, but it also creates imbalance in the body, and makes the latter vulnerable to outside harms. Therefore, a good doctor is the one who cures the disease and bring pleasure to the patient with food. He stresses that food therapy is always a priority. Mr. Sun prefers animal's organs in the food therapy for aged. For example, he uses powder of sheep's kidney to treat the lumbago. He suggests the viewpoint of 'Curing man's organs with animal's organs' and 'Strengthening man's organs with animal's organs,' and sets the theoretical foundation of 'Organic Treatment.' Mr. Sun's gerontology and food therapy received further development latter. The prescriptions contained therein had been widely used in 王懷隱's 『太平聖惠方』 and 陳直's 『養老奉親書』, both in the Song Dynasty. Eventually they had become a science of food therapy for aged patients.

We conducted the analysis using the data of the '2019 Korean Middle and Elderly Technology Acceptance Survey' to verify the comprehensive senior technology acceptance model. In this study, we examined the significant effect the relationship between behavioral intention to use the diital health devices and perceived usefulness, perceived ease of use, gerontechnology self-efficacy, gerontechnology anxiety, facilitating conditions, attitude to life and satisfaction through the structural equation. The results of the research model are as follows. First, the usefulness and ease of use had significant effects on intention to use. Second, the self-efficacy had significant effects on the intention to use. But they had negative effect. Third, perceived usefulness, self-efficacy and anxiety had significant effects on ease of use. Lastly, self-efficacy, facilitating conditions, attitude to life and satisfaction had significant effects on perceived usefulness. These findings highlight that verified the comprehensive senior technology acceptance model in Korea.

The purpose of the present study was to examine married female immigrants' life style and marriage satisfaction on the perception of preparing their old age. We also investigated how socio-demographic factors influence their Preparation for old age. For the study, -data were collected from 350 questionnaires obtained from female immigrants living in Chungcheongnam-do. Cronbach's ${\alpha}$ tests were conducted for reliability, and regressional analysis was conducted to test our hypotheses. The results of this study shows that there is evidence of relations among the sub-variables. However, we found attitudes to safety and material pursuit are not related to married female immigrants' preparations for their old age. On the other hand, the results indicate that their life style and marriage satisfaction influences their perception of preparing their old age in a positive way. Finally, sociodemographic factors such as gender, age, education, marriage status, occupation and income are shown to affect the women's perception of preparing their old age positively.

This research was based on surveys about differences of perception on retirement among the babe-boomers. Middle-aged men and women in their 40s' and 50s' residing in metropolitan areas centering around Seoul were the main targets for the surveys. Results indicated meaningful differences between men and women in the level of percection and expectation about their retirement. More specifically, men noted physical health, economic sufficiency and work as significant factors for happy retirement. Women, on the other hand, answered economic sufficiency first, and then physical health and relationship with spouse as the important variables for retirement. In addition, men and women portrayed different expectations for difficulties of retirement. Based on the survey results, this research proposed possible national, social, corporate, and individual approaches for secure retirement of the middle-aged baby-boom generation.

Aging is accompanied by a time-dependent progressive deterioration of multiple factors of the cellular system. The past several decades have witnessed major leaps in our understanding of the biological mechanisms of aging using dietary, genetic, pharmacological, and physical interventions. Metabolic processes, including nutrient sensing pathways and mitochondrial function, have emerged as prominent regulators of aging. Mitochondria have been considered to play a key role largely due to their production of reactive oxygen species (ROS), resulting in DNA damage that accumulates over time and ultimately causes cellular failure. This theory, known as the mitochondrial free radical theory of aging (MFRTA), was favored by the aging field, but increasing inconsistent evidence has led to criticism and rejection of this idea. However, MFRTA should not be hastily rejected in its entirety because we now understand that ROS is not simply an undesired toxic metabolic byproduct, but also an important signaling molecule that is vital to cellular fitness. Notably, mitochondrial function, a term traditionally referred to bioenergetics and apoptosis, has since expanded considerably. It encompasses numerous other key biological processes, including the following: (i) complex metabolic processes, (ii) intracellular and endocrine signaling/communication, and (iii) immunity/inflammation. Here, we will discuss shortcomings of previous concepts regarding mitochondria in aging and their emerging roles based on recent advances. We will also discuss how the mitochondrial genome integrates with major theories on the evolution of aging.
