In this thesis, a method has been developed to evaluate a disassembly time of a product. Some factors regards to affects disassemblibility are found by experiment and the value of disassembling time of elements and the computation formular are delived by using WF(work factor) method. The evaluated disassembling times are compared with real disassembling times of recyclable products, a desk toy computer case.

Recently, as the population becomes older, the elderly suffering increase, requiring multifaceted approaches to help them. Under such circumstances, this study was aimed at determining the effects of horticultural therapeutic program on the symptomatic alleviation of disorders in older people. The survey got the basic data of horticultural therapeutic activities for older people. The research method was investigated the horticultural therapy relation to literature documents and web sites. The classification of result by horticultural therapeutic activity was surveyed according to seasons, plant species, and activities. The horticultural therapeutic activities were carried out indoor space mainly. The ornamental plants were used more than vegetables for summer, autumn, and winter except spring. The horticultural therapeutic activities effected on senile dementia to decrease mental depression and increase the feeling of satisfaction for life, cognitive function, and physical promptitude. 우리나라의 노인인구증가는 급속하게 이루어지고 있다. 2030년에는 총인구 가운데 65세 이상이 19.3%, 70세 이상이 12.6%, 80세 이상이 3.4%에 도달, 65세 이상 노인 인구가 총 인구의 35% 이상을 차지할 것으로 예상되며, 이러한 증가속도는 세계에서 유례없이 빠르다(통계청, 2001). 현재 65세 이상의 노인의 87%가 장기 치료나 요양을 필요로 하며, 이들 중 31.9%는 일상생활 동작능력에 일부 장애가 있고, 3.5%는 스스로 모든 활동을 하는데 어려움을 겪고 있다(정경희 외, 1998). 또한 노인의 치매 유병율이 10% 내외로 추정되어(김한곤, 2002) 심각한 사회적 문제가 되 고 있다. 이에 따라 노인성 질환에 대한 의료적 혹은 약물처치이외의 대체치료에 대한 중요성이 강조되고 있으며, 특히 장애노인을 위한 신체적 능력 향상을 위한 프로그램으로서, 그리고 여가생활의 일환으로서, 나아가 노인의 삶의 질을 높이기 위한 방법으로서 원예치료가 주목받고 있다. 따라서 본 연구에서는 노인을 위한 원예치료활동이 더욱 적극적으로 활용될 수 있도록 구체적인 정원활동 및 원예치료활동의 모델을 제시하고자 문헌조사를 통한 기초연구를 실시하였다.

Between a wide range of distributed applications, this work is particularly focused on those applications which allow a group of persons, who are geographically distributed, to interact and cooperate exchanging different kind of information in order to realize group activities in a common work environment. In this paper we realized a study of this kind of applications to identify general and functional characteristics which will then enable us to determine their communication requirements. Also, we analyzed the existent support architectures to examine whether they support multimedia cooperative applications. Based on the results of analysis, we proposed a set of communication functions needed additionally to support these applications, using the ODP(Open Distributed Processing) modelling concepts, rules and view points as our global design methodology.

Objective: To determine the incidence of embryo retention (ER) in the transfer catheter following embryo transfer (ET) in blastocyst transfer and investigate whether retransferring retained embryos has an impact on reproductive outcomes in patients undergoing in vitro fertilization-ET. Methods: We retrospectively analyzed the records of 1,131 blastocyst transfers, which comprised 223 single blastocyst transfer (SBT) and 908 double blastocyst transfer (DBT) cycles. Each SBT and DBT group was classified depending on whether ET was performed without retained embryos in the catheter during the first attempt (without-ER group) or whether any retained embryos were found following ET (ER group) for the purpose of comparing reproductive outcomes in a homogenous population. Results: The overall incidence of finding retained embryos was 2.8% (32/1,131). There were no retained embryos in SBT cycles. In DBT cycles, implantation rates (30.0% vs. 26.6%), positive ${\beta}-hCG$ rates (57.2% vs. 56.2%), clinical pregnancy rates (45.3% vs. 46.9%), and live birth rates (38.9% vs. 43.8%) were not significantly different between the without-ER and ER groups. There were no significant differences in the mean birth weight (g) $2,928.4{\pm}631.8$ vs. $2,948.7{\pm}497.8$ and the mean gestational age at birth ($269.3{\pm}17.2days$ vs. $264.2{\pm}25.7days$). A total of nine cases of congenital birth defects were found in this study population. Eight were observed in the without-ER group and one in the ER group. Conclusion: Our results suggest that retransfer of retained embryos does not have any adverse impact on reproductive outcomes in blastocyst transfer cycles. Furthermore, our results support finding that SBT might be advantageous for decreasing the incidence of retained embryos in catheters.
