Charge dynamics in polymeric materials after aged under ac electric field using the pulsed electroacoustic (PEA) technique is reported. The emphasis is placed on charge decay. The charge dynamics of the ac aged additive free low density polyethylene (LDPE) samples under dc bias differ from the sample without ac ageing, indicating changes brought in by ac ageing. It is believed that a slow decay rate of charge in the ac aged sample is related to the formation of deep traps in the material. However, chemical analysis by infrared spectroscope (FTIR) and Raman microscope reveals no significant chemical changes taken place in the bulk of the material after ac ageing. Further experiments on irradiated LDPE have revealed a similar behaviour, i.e. the charge decay is slower in irradiated samples than that of fresh sample. The findings presented clearly indicate that space charge measurement can be used as a diagnostic tool to monitor ageing in polymeric materials.
As population ageing and shrinking accompanied by dramatically expanded individual life expectancy and declining fertility rate is a global phenomenon, ageing becomes its broader perspective of ageing well embedded into sustained health and well-being, and also the fourth industrial revolution speeds up a more robust and inclusive view of smart ageing. While the latest paradigm of SA has gained considerable attention in the midst of sharply surging demand for health and social services and rapidly declining labor force, the definition has been widely and constantly discussed. This research is to constitute a conceptual framework of smart ageing (SA) from systematic literature review and the use of a series of secondary data and Geographical Information Systems(GIS), and to explore its components. The findings indicate that SA is considered to be an innovative approach to ensuring quality of life and protecting dignity, and identifies its constituents. Indeed, the construct of SA elaborates the multidimensional nature of independent living, encompassing three spheres - Aging in Place (AP), Well Aging (WA), and Active Ageing (AA). AP aims at maintaining independence and autonomy, entails safety, comfort, familiarity and emotional attachment, and it values social supports and services. WA assures physical, psycho-social and economic domains of well-being, and it concerns subjective happiness. AA focuses on both social engagement and economic participation. Moreover, the three constructs of SA are underpinned by specific elements (right to housing, income adequacy, health security, social care, and civic engagement) which are interrelated and interconnected.

Given the importance of ensuring continued residency and maintenance of the 1st Planned New Town, which is the first of more than 20 such projects, this study aims to identify the factors determining the residents' living intention. The results show that age, gender, length of stay, and occupancy type are significant factors influencing their living intention. Among the environmental factors, the educational environment and shopping environment are crucial. This means that in order to achieve the "Ageing in Place" concept, it is necessary to improve the educational environment, provide a variety of commercial facilities and expand the living facilities. While it has no direct influence on the pros and cons of building remodeling, the results showed that when the living intention is used as a parameter, the transportation, educational, and shopping environment have an indirect influence on the pros and cons of building remodeling.
Various housing measures are needed for the rapidly aging society of Korea. In particular, the welfare policy for the elderly has changed towards the community care. Taking this fact into consideration, it is necessary to have the establishment of a system that offers the elderly appropriate welfare services at their appropriate residence (ageing in place) for the effectiveness of the community care. In this aspect, there are a number of implications to Korea to study merits and demerits of the Health Facilities for the Aged (HFA) in Japan. The society of Japan has been rapidly aging since 1970, and Korea is to face the same situation. As for the data of this study, a total of 2,393 facilities (as of November 1999) mentioned in the annual report of the Japanese Ministry of Health, Labor and Welfare were classified based on types of their establishment: (1) free-standing structures (603 facilities); (2) annexes to hospitals (981 facilities); (3) annexes to welfare facilities (511 facilities); and (4) annexes to clinics (298 facilities). Next, 239 facilities were selected through taking a sample of 10 percent from each type of the HFA mentioned above. This was done through the random sampling method with the computer program of MS EXCEL. The Implications of the results of analyses are as follows. First, most of the health facilities were planned with the scale that was larger than the scale of standard special nursing homes in terms of the total floor area. Precise equations that were to obtain precise results of the scale of the HFA and the appropriate number of residents were obtained through the method of the regression analysis. Korea and Japan have similarities in terms of culture, society and family relations; however, the two countries also have differences in terms of the application of laws on the establishment of houses, hospitals, and welfare facilities. As for planning the scale of the HFA, the realities of Korea should be considered. Second, as for the functional aspect of the HFA with a condition of returning home, the place before and after the HFA showed the pattern of 'from a residential place to a residential place' and 'from a hospital to a hospital.' This reveals a close correlation with the types of the HFAs and operational ways of the facilities. Its cause is considered to be the aspect of the operation and management of the HFA rather than the aspect of its function of providing services in association with medical and health facilities. Therefore, when intermediate welfare facilities are considered in Korea, it is strongly advised to consider the problem of annexes to other facilities and efficiency of sharing of the facilities in terms of its operation and management.
Current world population is rapidly ageing and the disabled population is expected to age seriously as well. The concern about the elderly and the disabled is increased largely not just the field of social welfare and service but the housing planning where the physical environment of everyday life is. Recently in Ireland, 'Universal Design Guideline for Homes' is established and proposed in public. It is considered as initial and special national policy for the socially venerable. The purpose of this research is to analyze the User Benefit Characteristics(UBC) of 'Universal Design Guideline for Homes in Ireland' and clearly organize the characteristics for comprehensive communication. The research subjects are 444 guidelines of 'Universal Design Guideline for Homes in Ireland.' The research is conducted by contents analysis technique, and each guideline is analyzed by the 4 main concepts of UBC- 'Behavioral Facilitation(BF)', 'Physiological Maintenance(PhM)', 'Perceptual Maintenance(PM)', 'Social Facilitation(SF).' As results, the User Benefit Characteristic of 'Universal Design Guideline for Homes in Ireland' is ordered by PhM>PM>BF>SF. The design guidelines are supposed to support ageing in place and sustainable living in the existing houses even though people are ageing or being disabled. 'Universal Design Guideline for Homes in Ireland' supports safe behavior and comfort cognition especially in indoor and surrounding outdoor environment. This research is significant for sharing the knowledge and comprehension of decreasing environmental stress of the elderly in specific, and could be utilized for developing new elderly housing in future.

The purpose of this study was to understand clothing condition of elderly men focusing on somatotype variation and satisfaction with ready-to-wear and to provide basic data in designing ready-to-wrar for the elderly men. The questionnaire method was used and one-to-one interviews were held for the elderly residents in Seoul, Deajon, Jonju, and Yeosu areas. The total of 275 questionnaires (from 148 elderly men in the 60's, 99 in the 70's and 28 in the 80's) were collected and used for statistics. SAS package was used for the statistics and the statistics were based on frequency, X2-test, ANOVA, Duncan's multifle range test. The results of the study were as follows; 1) Height (p< .05), weight (p< .001) and Rohrer index (p< .05) decreased significantly with ageing 2) The somatotypes of 75.6% were changed and the 70's 8t the 80's showed significantly (p< .05) higher changing rate compared to the 60's and more changes took place significantly (p< .001) with ageing. 3) The most preferred out wear was suit & tie and next was jumper or shirt. 4) For the mode of getting suit, the highest number 55.3%) purchased ready-to-wear, next (32.0%) was tailored and the least (12.7%) neither purchased nor tailored. The percentage of buying ready-to-wear significantly (p< .01) decreased with ageing. The main reason for getting tailor-made was not well fitting of ready-to-wear (20.7% out of 32.0%). And for the mode of getting suit, there was significant differance with income (p< .001) and pocket money (p< .01). 5) The most important factors in suit and shirt werefirst, size (fitness) and second, comfort in movement. 6) For the wearing feeling of suit, 55.3% showed discomfort. There was significant difference according to the age (p< .05) and pocket money (p< .05). The Discomfort increased with ageing and less pocket money. 7) 62.4% answered it uneasy to Pick out well fitting If comfortable suit. This showed their dissatisfaction with ready-to-wear. 8) As for the items of not well fitting, 64.4% answered in jacket, 60.8% in trousers, 46.0% in shirt. The above result shows that elderly men's somatotype changes as they age, suit is found uncomfortable and it's not easy for elders to pick out comfortable ready-to-wear. So, they seem to have a certain dissatisfaction in ready to wear. Therefore, there is a need for reorganization of size and developing pattern design according to measurement of elderly men.

The demand for a construction method capable of securing a safety environment and improving quality is increasing. There is a high risk of falling when working at a high place in an environment where it is difficult to secure visibility, such as an underground space, and there is a risk of falling if cement liquid waterproof materials are transferred to the top of the scaffold by manpower. In addition, when working on a high place in a poor environment, the quality uniformity of the upper part of the wall is deteriorated. In addition, as waterproof technicians gradually age and decrease, it is difficult to secure them, so it is urgent to prepare countermeasures against the shortage of waterproof technicians. Therefore, the purpose of this study is to develop cement liquid waterproof spouting construction equipment that can secure uniform quality of construction areas to prevent accidents and ensure safety of workers, improve work efficiency and quality due to improvement of work environment. The adhesion performance of the cement liquid waterproof material could be improved by about 20% in accordance with the use of the equipment.

The purpose of this study is to offer and analysis the stage of elderly in order to improve the quality of living environment of elderly in Korea. The results are as follows: Stage 1 of the early elderly appear to live with the elderly and their children, but stage2 and stage3 show the increase of the elderly couple. In case of elderly household, It showed reasons of living together, relationship between the elderly and their children for taking care of grandchildren and being dependent children. Also, residents currently had lived for a long time, especially get older, and ageing in a place has definitely. The Stage of elderly can be applied to understand the living environment for elderly in the future when housing for elderly solve a problem.
In this study, Exit light installed in offices, malls, hospitals, and factories were analyzed to analyze the luminance performance of CCFL and LED light sources. In addition, fire protection products with electrical characteristics such as Exit light may change their performance due to ambient temperature, humidity, and dust. So it was extracted by installation place and analyzed its characteristics. As a result of the experiment, Exit light for CCFL type showed the value of 'ratio of luminance 2' for large, medium and small. Considering that the reference value was 'lower than 9', the value was very good and it can be seen that there is almost no change in ratio of luminance due to aging. The Exit light for LED type showed a value of 'ratio of luminance 5', which means that the light on the display surface is not uniform. In addition, there was almost no change in ratio of luminance due to ageing, but the ratio of luminance was larger than Exit light for LED type. This is an unsatisfactory result from a visual point of view. To improve this, it is necessary to disperse the light of LED light source and strengthen the regulation on ratio of luminance.

This paper describes the checking results and some problems of guard lamps installed in the field. The guard lamp providing night security for people is installed outdoors and exposed to the natural factors causing secular ageing and the people's vandalism, etc., thus it is prone to get troubles in function. In fact, the guard lamps has been left without considering the fundamental measures in the legislative system in spite of the loss of lives due to the electric shock accidents repetitively taking place every year. This study arouses people's attention to the risk due to the lack of management and maintenance of the guard lamp by investigating the recent technology and the actual operating conditions and some problems and countermeasures were ultimately deduced. In this process, we reflected on the various opinions through fieldwork and had a couple of consultations with field staffs, manufacturers concerned and active officers with local autonomous entities.
