This study is designed to investigate what elders think about the meaning of aging. We have used Q-methods to identify meaning of aging from elders, and developed self-referenced surveys to analyze characteristics In this study, we used a non-structured method to select Q sampling. From 183 Q populations, we selected 36 Q sampling. A total of 32 persons sixty-years or older were randomly selected for P samples, When the Q-sorting was complete, we interviewed the participants at both end of the extremes(agree or disagree), and documented their responses. We used PC QUANL to process the data and used principal component analysis for Q factor analysis. There were five subjective types for the meaning of aging by elders. Of the 32 P-samples of elders, 11 were identified as Type 1, 7 as Type 2, 2 as Type 3, 8 as Type 4, and 4 as Type 5. Type 1 : 'Matured elders' Elders wished the well being of their children, thought older persons should maintain good health, worried about becoming senile, and dependent God believing in life after death. Type 2 : 'Assertive-Rights' Elders categorized as Assertive-Rights insisted on their rights to life as a person. Type 2 elders characterized themselves as people who should keep themselves healthy, become weak and lack sexual desires, act selfish like a child, need to be protected, and be financially independent. Type 3 : 'Passive-Dependents' Elders characterize themselves as those who pray for their children's well being, worry about the children even after their death. and becoming senile. Type 4 : 'Hopeless' The 'Hopeless' type of elders characterized aging as a time to pray for their children, insignificant beings, thoughts were selfish and child-like, poor, worried about going senile, regret their life overall, and preferred to die than to live as an old person. Type 5 : 'Attached-Present' The 'Attached-Present' type of elders thought elderly characterized themselves as acting selfish and child-like, wiser, anxious, regret their life, stand aloof of greed and worldly things, being a model for the society, and deserving to be treated with filial respect. Thus far, Korean elders seemed to have a positive and negative meaning of aging due to the current changes in the society, value system, and family structures. The above five subjective meanings of aging confirm that we need to approach and nurse the elderly differently. Years of aging are a part of and a natural process of life with various physical, psychological, and sociological changes. Nurses need to assist elderly to find the positive meaning of their life by providing appropriate physical, psychological, and social support at an earlier stage in nursing. Based on this study, we could derive the following two implication from the perspectives of science of nursing to care for elders. 1) Based on the studies investigating the type of meaning of aging, we could develop tools to assist in nursing intervention programs for elderly. 2) Based on research on the meaning of aging for different developmental stages of life, we could develop a model for roles for different family members in nursing and caring for the elders.

Amongst society's transitional presuppositions towards the future, population aging is the most critical issue in Korea. Immediate attention to devise a countermove is required. One of the major trends appeared in retirement communities of advanced countries is social integration which has been considered as a promising future direction of elderly housing development. This study aims to find out social integration characteristics and to categorize local engagement types of recent retirement communities through the characteristics of sharing common facilities and programs. Data were collected through mainly web site and literature reviews. Contentent analysis technique was used. Ten CCRC cases were selected through web search using the major key words such as 'intergenerational'. As a result, community engagement types were classified into six categories by the degree of sharing both physical and program resources between the retirement community and local area. This type can be utilized to develop alternative housing and retirement community for the older adults as a new model which activates the resident and vitalizes the retirement community through local engagement by physical and social resources.

Rubber material properties and useful life evaluation are very important in design procedure to assure the safety and reliability of the rubber components. In this paper, the evaluation of characteristics and useful life prediction of rubber component for elevator cabin were experimentally investigated. The material test and accelerated heat-aging test were carried. Rubber material constants were obtained by curve fittings of simple tension, pure shear and bi-axial tension test data. Heat aging test results changes as the threshold are used for assessment of the useful life and time to threshold value were plotted against reciprocal of absolute temperature to give the Arrhenius plot. By using the rubber material and component test several useful life prediction equations for rubber component were proposed. Predicted useful life of rubber component for elevator cabin agreed fairly with the experimental lives.

Due to the rapid increasing in the aged population, it calls for social countermeasures urgently. Especially, there are increasing needs of space environment to support physical and spiritual characteristics of elderly. When designing space environment including house, there are growing consideration for elderly and extending appreciation of aging. The purpose of this study is to investigate the perception on environment planning for the seniors among university students who majoring in Housing & Interior Design and who visited the Aging Simulation Center located in Seoul. The Aging Simulation Center gives a chance of space design to support the elderly based on the experiences of daily living for the designers who design environment for elderly. Questionnaire survey was conducted to obtain data from 93 university students in their 20s majoring in housing and interior design who visited the Aging Simulation Center. The research findings showed that the recognition for design elements of residential environment for the elderly of respondents was changed toward positive way after visiting the Aging Simulation Center. The Aging Simulation Center was an effective educational environment for the preliminary designers to understand aging and the importance of appropriate design for users' needs. That is, aging simulation space can improve recognition of necessity of universally designed environment to support the elderly. Handrails around bathtub and wash basin, stair slope, electric auto-level controlled kitchen counter and kitchen cabinet were especially perceived for the respondents as very essential design elements to support the aged.

Rapidly aging society extends the span of aged life of the elderly people longer than before and this trend raises the issue of holistic health of the aged including their physical, psychological and social health making it necessary to study for environmental development to support this trend. This study intends to explore the direction of residential planning to support the deterioration phenomenon of social networks due to aging. Social networks here are treated as basic conditions for social health. This study researched the diverse types of elderly housings in preparation for the aged society and their spatial characteristics, social affordance characteristics and their potentials for social interactions from the viewpoint of their social relations. literature studies with contents analysis method was used. The results of this study were arranged primarily according to the characteristics of social relations by types of housings. Socially integrated types of housings can be found as inclusive housing type as they have both social characteristics that can be found in houses in general and the elderly housings, they should be considered as desirable types in Korea where collective houses are most popular. Form the existing housing plans housing plan direction should move toward socially integrated housing plans that can protect the elderly people collectively and the direction of housing plans here means the direction from more macro-perspective viewpoint. Therefore, the results of this study are meaningful in adding interpretation from the viewpoint of social relations respective housings and promoting housings for the elderly people more desirably.

The purpose of this study is to introduce ubiquitous home services for the aged. In comparison with general ubiquitous homes, ubiquitous homes for the aged have two major characteristics. First, the service contents should be expanded and strengthened. Second, the services should be customized to each individuals. The primary objective of a ubiquitous home for the aged is health care. The three affordances for this objective are 1)prevention of sickness and reducing the speed of aging process, 2)technical assistance for disability, 3)recovering and enhancing the physical and cognitive function. For this purpose this paper analyses the characteristics of the aged and current ubiquitous technology and ubiquitous home service, thus providing an outline for ubiquitous services necessary for aged people.

This paper reports the investigation of the physical and chemical characteristics of the prepared 3Pt-2MgO-$3ZrO_2$-$2CeO_2/Al_2O_3$ DOC, based on its hydrothermal aging. As a result of impregnating and reducing the $H_2PtCl_6$ $6H_2O$ precursor on a ${\gamma}-Al_2O_3$ basis, it was well dispersed into small particles with the range 2-3nm. This was because the $Al_2O_3$ acted as a barrier to prevent movement of the catalyst particles. For a hydrothermally aged catalyst for 9h at $700^{\circ}C$, its performance when purifying harmful gases decreased compared to a fresh catalyst, but its specific surface area was at the same level. This was because the performance of the catalyst was reduced by the sintering of the precious metal Pt, rather than by washcoat sintering and pore clogging. For an excessively hydrothermally aged catalyst for 9h at $850^{\circ}C$, Pt grew into an approximately 50nm class, formed a cluster compared to a fresh catalyst. The $CeO_2$ promoters also formed clusters among components of the same type, reducing their specific surface area to $114m^2/g$, which was 14% less than a fresh catalyst.

The number of elderly citizens has risen in Korea and resulted in an aging society. Correspondingly, the social interest in the aging population has escalated immensely; however, research or product development on the quality of life for seniors has shortcomings. Healthcare smart clothing is required to help the elderly with changes and weaknesses that follow aging; however, there is unfortunately insufficient amounts available. This study explores the feasibilities of smart clothing for seniors based on a universal design. Based on previous research, we analyzed the universal design theory, body shape characteristics and design requirements for seniors, and heart rate measurement method. The design is different according to body shape and body shape is different between sex, age, and body race; therefore, subjects were limited to 70-74 year old Korean males in this study. This study proposes a guideline for heart rate sensing clothing that satisfies the 'universal design' aspects as well as the functionality of heart sensing, senior's physical characteristics and needs. It has broadened the range of smart clothing, which was once limited to the younger generation and provided a foundation for the development of specialized smart clothing for seniors.

In this paper, we evaluated the suitability of converter slag as concrete aggregate by measuring physical and chemical characteristics of converter slag. The converter slag mainly contains SiO₂and CaO as the chemical composition. The reaction with water and a little of free CaO in the slag causes slag's volume to expanse. Therefore, we used several aging method in order to decrease the characteristics of slag volume expansion. Then the compressive strength of concrete with the converter slag aggregate is measured.
