Purpose: The purpose of the study was to identify factors influencing health promotion behavior of late-middle aged women. Methods: The subjects were 128 women who were attending a cultural center located in B metropolitan city. Data were collected from July 1 to July 31, 2016. Data were analyzed using descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson correlation coefficient, Stepwise multiple regression with SPSS/WIN 23.0 program. Results: Health promotion behavior of later middle-aged women was different by general characteristics such as religion, exercise, economic satisfaction, life satisfaction, and leisure time activities. Health promotion behavior had a positive relationship with health perception and perception of successful aging, and a negative relationship with aging anxiety. Health perception, perception of successful aging, exercise, leisure time activities (exercise and social activity) were verified significant factors influencing health promotion behavior accounted for 38%. Conclusion: The results indicate that health perception and perception of successful aging influence health promotion behavior of late-middle age women. It would provide the basic data for the development of program aimed at improving health promotion behavior of late-middle age women.

Purpose: This study was done to examine the relationship of successful aging, depression, and family function in rural elders. Method: A descriptive correlation study design was used and data of the study were collected from 272 people who were overn 65 years of age and lived in a rural community. Result: The mean score for successful aging was $2.28{\pm}0.46$ points of a maximum 3 points. The elders showed a moderate degree of family function ($6.98{\pm}2.83$ points out of 10 points). The mean score for depression was $6.13{\pm}3.75$ points out of 15 points. There was a statistically significant correlation between successful aging and both depression (r=-.659, p<.001) and family function (r=.621, p<.001). Stepwise regression analysis was done to verify factors influencing successful aging. Depression was the dominant factor accounting for 43.2% of the total variance, followed by family function and age in that order. Inclusion of all of the study values resulted in an explanation power of 61.7%. Conclusion: The study results suggest that the provision of individual socio-psychological, and economic measures is important to promote successful aging in rural areas which are different in terms of socio-cultural as well as regional factors compared to urban areas.

The purpose of this research was to identify causes of damage of wax-treated volume of "The Annals of the Joseon Dynasty". As one of the efficient restoration methods, analyses of damaged state of reproduced wax-treated paper through tests of degradation of wax-treated paper under an artificial setting were performed, and in particular, differences between lightness and acidity were observed. On the whole, it was confirmed that yellow wax-treated papers were more stable than white wax-treated papers against artificial aging treatment, which is thought to be because the white wax-treated paper was more affected by a variety of substances interacting with paper than yellow wax-treated paper under artificially aged conditions, which were added in the course of refinement and processing operation such as decolorization and deodorization.

Recently, cultural property policies have changed from the preservation of cultural assets to the utilization of cultural assets. In historic villages, more and more traditional housings have been used as lodging facilities. On the other hand, low birth rates, aging population, declining population due to population outflow to the cities, increasing vacant houses, and aging buildings are tasks of historic villages. To be preserved the historic villages continuously, it is time to review how to regenerate and utilize the growing number of vacant houses. This study targets Tambasasayama city, which is drawing attention to the regeneration and utilization of vacant houses among historic Japanese villages. We want to analyze the operation systems and deregulation of a traditional housing regeneration project in Tambasasayama city and draw suggestions for the regeneration and utilization of vacant houses in traditional villages in South Korea.

This study shows the research of causes of deterioration of the amber from foreign cases. It also presents the conservation treatment as well as tests to examine the effect of the organic solvents on the amber in order to find reversible and safe reinforcing agent which will prevent further damage of the artefact. The result showed that there was no noticeable change in the weight of the artefact as well as on the appearance of the surface when Mineral spirit(White spirit), which is aliphatic hydrocarbon group, and Xylene, aromatic hydrocarbons group was applied. Reinforcement and restoration was carried out using Paraloid(R) B67, which has a broad option for the solvent, in Xylene. Finally, it is recommended that the use of polar organic solvent in the conservation treatment of amber artefacts should be limited.

Ambers are composed of polymer molecules which contain aromatic moieties such as benzene, naphthalene, phenanthrene and anthracene. They emit fluorescence when irradiated with ultraviolet light, which was used for confirming an amber. The fluorescence of amber, however, tends to decrease as the surface of amber is weathered with light, heat, oxygen for a long time. In this study, the reliability of confirming amber with its fluorescence by measuring the changes of fluorescence after artificial aging. Aging factors were UV light (${\lambda}$=340 nm), oxygen with heat (100%, $90^{\circ}C$) and heat ($90^{\circ}C$) and aging time was for 5, 15, 30 and 60 days, respectively. In the excitation and emission spectra of amber, the intensity decreased and the maximal wavelength was shifted to longer wavelength with artificial aging time. Especially, there was a drastic decrease in the intensity of spectra to 1.7% of initial value after 60 days aging under oxygen with heat. Only in Colombian amber there showed an increase of fluorescence intensity for a certain aging time, which could be explained by the production of aromatic ring in the presence of light and heat. Conclusively, the fluorescence can be lessened by the natural weathering with light, heat and oxygen and it is not accurate to recognize amber just with UV irradiation method.

Korean society is running fast toward a super aging society. This means that new solutions for new problems of aged people are needed. An important area to prove is the aging-friendly neighborhood environments supporting casual contacts and meetings of old residents. This study attempts to suggest neighborhood design indicators which support casual contacts and meetings of old residents. The subjects were 24 professionals who had studied on housing environment for the elderly. They answered through the on-line questionnaire. The questionnaire consisted of items which evaluate the appropriateness of classification of neighborhood area and the indicators of each area using 5-points Likert scale. Also open questions asking adding or eliminating areas or indicator and other opinions were included. On the basis of these answers, the aging-friendly neighborhood design indicators supporting contacts and meetings of old residents was developed. They are consisted of 7 areas in neighborhood and 60 indicators. Those areas were semi-public residential area, commercial area, cultural & educational area, health & medical area, park & green area, walkway, and public traffic facilities. This would be used to design the neighborhood environments that are aging-friendly and facilitating casual contacts and meetings of all residents, especially old residents.

Purpose: This was a methodological study that aimed to develop a measurement scale for aging anxiety among middle-aged women. Methods: In this study, construct factors were extracted, and a conceptual framework was established through an extensive literature review and in-depth interviews with middle-aged women. Under the conceptual framework, 44 preliminary items were constructed, and a preliminary scale of 25 items was completed after two rounds of expert validation and item review. For this study, data were collected from 201 women aged 40~59 years, and the construct validity and reliability of the preliminary scale were verified. Results: To verify the construct validity, exploratory factor analysis was conducted. Four factors containing 19 items were extracted. Concurrent validity of the developed scale was verified with Pearson's correlation analysis. The final scale comprised 4 factors ("Social valueless", "Physical weakness", "Concern about changes in appearance", and "Expectations of old age") and 19 items. The Cronbach's ${\alpha}$ value was .91. Conclusion: The scale for measuring aging anxiety in middle-aged women developed in this study validly reflected the peculiarities of aging anxiety in middle-aged women, who experience many physical, emotional, and social changes. The scale can be said to reflect the cultural background, as it reflected real experiences gained through in-depth interviews with middle-aged women.

In the digital era, large archives of information and Internet accessibility make information search, including image search, easier and affordable, even from remote locations. Information transmission and sharing can be performed instantly, at any moment. In the case of images, there are risks of transmitting and recklessly sharing intentionally modified images. Such modified images can also be transmitted and used as an additional source of information by followers. In this study, historical portraits of Yu Kil-Chun are shown, who was the first Korean student to study in both Japan and the United States. He was an intellectual, writer, politician, and independence activist of Korea's late Joseon Dynasty. Using image processing software, the portrait images were compared to investigate aging effects and artificial modifications. Statistics of red (R), green (G), blue (B), and L^*, a^*, and b^* values of every pixel in the selected identical areas of the portraits were compared to identify possible causes of variations, including aging effects and artificial modifications. Sepia toning, used in black and white photographs until the 1930s, and modern digital sepia toning can be very confusing owing to their aging effects. The importance of preservation of physical copies and preservation of context (interconnections between data and between documents) is discussed from archiving and conservation science perspectives.
