고력볼트 인장접합 형신인 Split Tee 접합은 접합부의 효율성과 시공성이 우수하여 유럽등지에서는 중저층의 건축물에 많이 적용되고 있으나 국내에서는 널리 사용되지 않은 상황이다. 이는 고력볼트와 Split Tee를 구성하는 판재의 강성에 따라 지레작용의 효과를 포함하는 보트의 인장 전단파괴와 Split Tee의 송성파괴가 상호작용을 일으켜 해석과 설계가 복잡하다는 점과 시공상의 정밀도 확보가 쉽지 않기 때문이다. Split Tee접합에 관한 연구는 미국, 일본, 유럽등지에서 다양한 방법으로 진행되고 있지만 국내의 경우 아직 초보적 단계에 머물고 있다. 본 연구에서는 실험을 통한 Split Tee접합부의 거동, 즉 지레작용의 영향과 그에 따른 반력작용의 특성을 파악하여 Split Tee접합 설계를 하는데 있어 기초 자료를 제공하고자 한다. Split-tee connection with High Strength Bolts is normally used in low and middle rise buildings in Europe because the structural efficiency and installation work of connections are excellent. However, the domestic situation is different from that in Europe. The analysis and the design for the T-split connection are complicated, because the structural behavior often T-split connection with High Strength Bolt is governed by so many parameters, i.e., prying action, bolt's tension, shear failure and plastic failure of flange plates. Many researches regarding the structural behavior of the split-tee connection have been undertaken in other parts of the world, such as the, Americas, Japan and Europe, but in the domestic context, this is a pioneering study. Therefore, the purpose of this paper is to supply basic data for the design of T-split connection, and to verify the structural characteristics that define reactions to prying action, based on an experimental study.

Korean society has recently experienced a rapid aging of its population. The increase in the number of older people with chronic illness, as the number of older people increases, calls our attention to such issues as who cares for those elderly, and how? Family has served as the major source for long-term care for the elderly in various countries including Korea. The primary caregiver is usually a woman in the family, but the social circumstances around women, families, and older people has been changing. Especially, the increase of women`s participation in labor force has a profound impact on the situations of family caregiving. The purpose of this article is to deepen our understanding on how employment and caregiving are related with each other among women who are the primary caregiver for the elderly, and thus to explore the effective way of improving the quality of life among caregivers and older people. The literature review helps us understand how employment affects the caregiving stress among women caregivers. The comparison of employed caregivers with unemployed caregivers suggests the positive impact of employment among caregivers. It might be that multiple roles enhance the availability of caregiving resources and the capability of caregivers themselves. However, the comparison of those who are caregivers and those who are not among employed women reveals that the additive caregiving role has a negative impact on job performance of employed women. Time conflict, overload, role conflicts, and ambiguity in cultural norm about elder care role are those which are identified to contribute to the poor job performance among employed caregivers. Important are to distinguish care manager role from care provider role. Care manager arranges various types of services to meet the needs of their older parents by purchasing them in market, while care provider herself supply all the services. There are differences between cue managers and care providers in ways to accommodate their job schedule to meet the caregiving responsibilities, suggesting that care managers have more flexibility and better adjustment in their job. Policies for the elderly in Korea have limitations in that those policies could not fully reflect the changes in situations which women, families, and older people reside in. The literature review on women`s employment and family caregiving suggests the several implications for policies for the elderly.
