Current statistics reveal remarkable prolongation of the average longevity in this country for the past decade. Welfare of the aged is no longer sole concern of the person or/and family. but has aroused social concern on the community and national level. This study was designed to assess social, economic and emotional needs of the aged. and to identify problems they are confronting. Data were gathered through questioning 273 subjects living in Seoul from July 25, to August 31. 19 80. Frequencies and percentile scores were analysed to describe the fact. and the significance of int or-variable differences was tested by Chi-square method. Results are : 1. Majority of the subjects (male : 65.38%). (female : 62.13%)“talk about past experiences”to re-collect their past days, the difference between male and female respondents was not significant. 2. Except few who earn their pocket money (4.21%). majority were doing household errands (34.52% ) and looking after their garnd children (29.26 ％）. Main sources of their pocket money revealed to be their children (84.02%) and their own savings (24.64% ). Except few (15％）engaged with social activities directly or indirectly. leisure hours are spent in chatting with aged neighbors (44.81%). Highest in the rank order on the joyous moments for the aged revealed to be when the members of family living apart paying a visit (male : 37.5%, female : 63.72%)difference of male and female was significant ( P<0.05). Among female respondents. significant difference between age group was revealed (p<0.05). 3. Majority prefered sin91e houses (84.30% ). as residential environment. the suburban (36.26% ) area was the filet in the rank order : difference between age group and the educational status were not significant. Majority of respondents revealed to have their own room in the house. The first preference was given to live with their children (68.86%). Memory of the past (37.36% )revealed to be the highest in the rank order among the reasons why they dislike moving the house. 4. Majority favored current welfare benefts provided for the old age. however. the ideal way to live at their old age they responded was to live on their own savings (50.54%). 5. Majority revealed to be daunted occasionally (62.27%) by not being less active (34.16%) socially and by poor physical health(29.75%). Male and female differ in the causes of loneliness significantly (P <0.001) : retirement (37.89%) in ale and helpessness (43.05%) in female revealed the highest in the rank order. Majority talk over their feelings with aged neighbors to overcome the loneliness. 6 Majority were in favor of planting and looking after pet animal in the house. however. male and female differ in the kind significantly (p <0.001), 7. Majority think about death and dying occasionally or more (84.11% ). Many of the respondents believes in the life after life (53.49%) : female revealed to be significantly higher (p <0.01). and subjects with christian belief were significantly higher than non-christians (P<0.001). Attitude towards death and dying differs significantly between male and female (P <0. 001) and between christians ans and nonchristians (p <0.001). Highest preference was given to simple funeral (69.85%). Precious heritage that they would pass on to their descendants was onoscience and ethical value(57. 51%) : christian response as the first value was christian belief (52.38%).

본 연구의 목적은 중력 하중에 저항하도록 설계된 플랫 플레이트 외부 접합부의 이력 거동을 평가하는 데 있다. 이러한 목적을 위하여 2/3의 크기가 조정된 PT 슬래브-기둥 외부 접합부 2개와 RC 슬래브-기둥 외부 접합부 1개를 대상으로 실험적 연구를 수행하였다. 여기서 각각의 PT 실험체는 서로 다른 강선 배치 형태를 띄고 있다. 중력 하중은 동일하게 설정하였고, 지속적인 정적 하중 하에서 유사 정적 횡하중을 적용하였다. 한편 모든 실험체는 ACI 318-05과 ACI 352.1R-89에 근거하여 기둥 폭 내에 하부 철근을 배근 하였다. 또한 PT 외부 접합부의 이력 거동에 대한 일반적인 결론을 얻기 위하여 기존 연구자들의 실험 결과와 함께 비교하였다. 이번 연구를 통하여 강선의 배치는 PT 접합부의 이력 거동을 결정하는 중요한 변수임을 확인하였다. 즉 횡변형 성능, 에너지 소산 능력, 파괴 메커니즘, 그리고 연성 능력이 강선의 배치에 따라 다르게 나타났다. 또한 ACI 352.1R-89에서 구조적 일체성을 위해 제공된 하부 철근의 양은 모멘트 역전에 의해 발생된 정모멘트를 저항하는데 있어서도 적절하다는 것이 밝혀졌다. 또한 실험체의 전단 강도는 강선의 포스트 텐션에 의한 평균 콘크리트 압축 응력($f_{pc}$)의 효과가 고려된 식이 그렇지 않은 식보다 전단 강도를 정확히 예측하는 것으로 나타났다.
