Aging is one of the major tasks that our country should resolve. To deal with aging problems, many countries have introduced various new concepts such as active aging, productive aging, and successful aging, well aging and anti-aging. This study suggests a new concept, digital aging, to tackle aging problems, and we use this concept to explore the new policy and policy areas for aged people. Since this concept is not well defined yet, this article focuses reviewing existing research literature. Instead of focusing the negative aspect of aging, this study investigates how to use the digital technology to build such images that the old man can be continuously learning, active and productive.

This study aimed to identify the effect of the active aging on life satisfaction and present an improvement strategies to increase life satisfaction in elderly people. Active aging is divide into three aspects; health, participation and security. The subjects were people older than 55 years who were enrolled in Korean Retirement and Income Study. The influencing effect was analyzed by a hierarchial regression. Key factors associated with active aging influencing life satisfaction were subjective health, mental health, participation in the labor market, income, and housing while subjective health was a determinant factor that best describes the effect of the active aging on life satisfaction. On the basis of above result, this study suggests that there needs to be an effort in improvement of physical and mental health, participation in the labor market, and housing at national and regional levels.

Due to the aging of economically active population in the world, the average age of workers in the domestic construction industry is also steadily increasing. This study analyzes the aging of construction workers in small-size construction sites in Busan, where the aging of the economically active population is the most severe in Korea. As a result of the study on the aging of construction workers in six construction sites with a construction cost of less than 500 million won in Busan, it was found that 65% of the workers were over 50 years of age. In addition, several experts interviews and survey revealed that 'securing welfare facilities for construction workers' and 'diminishing prejudice about the construction industry" were the most urgent and effective methods to overcome the aging problems. The results of this study can be served as basic data to solve the aging problems in the industry.

The thermal degradation of low density polyethylene (LDPE) will accelerate the production of carbonyl groups (C=O), which can act as the induced dipoles under high voltage. In this paper, we researched the dielectric properties and space charge behavior of LDPE after thermal aging, which can help us to understand the correlation between carbonyl groups (C=O) and electrical properties of LDPE. The spectra results show that LDPE exhibit obvious thermooxidative reactions when the aging time is 35 days and the productions mainly contain carboxylic acid, carboxylic eater and carboxylic anhydride, whose amount increase with the increasing of aging time. The dielectric properties show that the real permittivity of LDPE is inversely proportional to temperature before aging and subsequently become proportional to temperature after thermal aging. Furthermore, both the real and imaginary permittivity increase sharply with the increasing of aging time. The fitting results of imaginary permittivity show that DC conductivity become more sensitive about temperature after thermal aging. On this basis, the active energies of materials calculated from DC conductivity increase first and then decrease with the increasing of aging time. In addition, the space charge results show that the heterocharges accumulated near electrodes in LDPE change to the homocharges after thermal aging and the mean volume charge density increase with the increasing of aging time. It is considered that the overlaps caused by electrical potential area is the main reason for the increase of DC conductivity.

The purpose of this study is to compare rational process of active ageing and productive aging based on the theory of planned behavior. The effect of post-retirement may be influenced by attitude, subjective norms, and perceived behavioral control for old aged workers, then we tested the effect of mediating role of post-retirement preparation on active ageing and productive aging. And we conducted additional analyses of mediating role of post-retirement preparation respectively. Conducting a survey research to 192 employed old aged workers, the data was analyzed by Structural Equation Modeling. The result of this study found the positive effects of attitude and perceived behavioral control on active ageing through post-retirement preparation. There were negative effect of subjective norms and positive effect of perceived behavioral control on productive aging through post-retirement preparation. According to additional analyses, the mediating effect of social post-retirement preparation was significant on active ageing, and the mediating effect of emotional and social post-retirement preparation was significant on productive aging. Suggestions for future research and practical implications were provided based on the findings.

Taste-active compounds (e.g., amino acids and nucleotides) play an important role in contribution to the gustatoty sensation of food. The current study aimed to examine the differences in taste-active compounds between different beef muscles, breeds and aging periods. We have chosen the longissimus dorsi and semitendinosus muscles of Hanwoo breed and longissimus dorsi muscle of Angus breed for the investigation of the aforementioned compounds. Hanwoo muscles were aged for 7 or 28 d, and Angus samples were aged for 28 d at $4^{\circ}C$. Results revealed that 8 out of the 18 detected free amino acids (FAA) showed significant (p<0.05) differences between the two Hanwoo muscles. Twelve FAAs showed aging effect (p<0.05) in which the amounts of 8 FAAs significantly increased as aging time increased. Inosine 5-monophosphate (IMP), hypoxanthine (Hx) and inosine showed significant (p<0.05) differences between the Hanwoo muscles, aging resulted in an increase in amounts of these nucleotides. Hanwoo beef had significantly (p<0.05) higher total amount of sweet amino acids than the Angus ones in that 15 amino acids showed differences (p<0.05) between the two breeds. Amounts of guanosine 5-monophosphate (GMP) and Hx were significantly higher (p<0.05) for Angus beef. Current study indicated that muscle type, breed and aging period had large variations in free amino acid and nucleotide contents, which may subsequently affect the taste attributes of cooked beef.

The purpose of this study was to analyze the policy and programs of the Seoul50Plus Foundation and to propose policies and programs to promote active aging of middle-aged and elderly people. A single case study was utilized as a research method. The analysis framework of case was approached with four frameworks: the context of policy and program, ideology-goal analysis of policy and program, supplier and customer analysis of policy and program, and process and domain analysis of policy and program. The analysis data included the homepage content of the Seoul50Plus Foundation, related 50+ policy and program data, active aging research papers at home and abroad, and presentation and meeting materials. The results of the research showed that the policy and program background and environment were essential elements for responding to environmental changes in the aging society. In terms of the philosophy-goal, job creation, social participation, and approach to life design were systematically carried out for the ideology of 'creating a new life vision' and promoting active aging. In terms of subject-target, the subject of policy implementation is systematically composed of three stages: 50+ foundation, 50+ campus, and 50+ center. The target was limited to 50+ generations(age 50~64) and had a problem that is limited to applicants. In the process-area analysis, programs such as educational support, work and entrepreneurship support, counseling information, and new-age cultural creation activities were designed to increase added value according to the characteristics of the middle-aged people. In conclusion, the future Seoul50Plus Foundation's policy and lifelong learning programs need to be systematically promoted through cooperation with businesses and universities, expanding the target audience, matching the characteristics of the middle-aged and elderly, and linkage among programs.
