This study dealt with the experimental modal analysis of the perforated rectangular plate coupled with fluid. The natural frequencies of the perforated plate and solid plate in air were obtained by the analytical method based on the relation between the reference kinetic and maximum potential energy and compared with the experimental results. Good agreement between the results was found for the natural frequencies of the perforated plate in air. It was empirically found the natural frequencies of the perforated plate coupled with fluid. The transverse vibration modes, in-phase and out-of-phase, were observed alternately in the fluid-coupled system. Additionally, the effect of distance between perforated plate and solid plate on the fluid-coupled natural frequency was investigated.

싸주아리쑥 지상부의 80% MeOH 추출물로부터 얻어진 EtOAc 분획물에 대하여 silica gel 및 ODS column chromatography를 반복하여 diterpene을 분리하였다. 화합물의 화학구조는, NMR, MS 및 IR 등의 스펙트럼을 해석하여 phytol로 동정하였다. The aerial part of Artemisia herba was extracted with 80% aqueous MeOH and the concentrated extract was partitioned with EtOAc, n-BuOH and H_(2)O, successively. From the EtOAc fraction, a terpenoid was isolated through the repeated silica gel and ODS column chromatographies. From the result of physico-chemical data including NMR, MS and IR, the chemical structure of the compound was determined as phytol.

Objectives : Recent genetic studies have suggested a preferential transmission of the Dopamine D5 receptor gene (DRD5) 148bp marker allele. The aim of this study is to test the association between DRD5 and ADHD. Methods : 106 Korean children with ADHD and their parents were analyzed using the transmission disequilibrium test (TDT) and haplotype-based haplotype relative risk test (HHRR). And also the ADHD children were compared with 212 ageand gender matched normal controls. Results : We found the evidence for an association of short alleles of DRD5 dinucleotide repeat polymorphism in both Case-control and family based studyies. Additionally, we observed some evidence for biased transmission of allele 152 bp and 144 bp. Conclusion : Our results lend credence to the notion that the relationship between ADHD and DRD5 is complex. The number of cases and informative transmissions in our study were small, therefore it would be premature to make any conclusions Con-ceming the role of DRD5 in ADHD. Further work is needed to support these findings.

장혜경,유태명 한국 가정과 교육 학회 1994 한국가정과교육학회지 Vol.6 No.2

This study developed and proposed a lesson plan for the area of "Human development and family relationship" in secondary home economics curriculum. In current, educational practice in secondary home economics curriculum, the employed goal and the nature of home economics are neither stated specifically nor closely interrelated. This problem has led us not being able to achieve pursuing goal of home economics education and to employ appropriate teaching methods. In view of this situation, the purpose of this study was to propose a plan reflecting the contents and teaching methods to overcome difficulties and inefficiency in the current practice of secondary home economics education. The theoretical background of the lesson plan was based on the Marjorie M. Brown's philosophy of home economics which can be summerized as follows: 1. The goal of home economics is to help individuals and families to become autonomous in their own family life and to be more capable of interacting with others in behalf of well-being of the family and of social evoluation toward a free society. 2. The characteristics of home economics is conceptualized as practical science and personal serviec profession. 3. The nature of problems which home economics should deal with is perennial nad practial. 4. Practial reasoning composed of historical understanding, critical action, and reflective thinking is appropriate for the previously mentioned goal and characteristics of home economics and for dealing with perennial practial problems. The lesson plan was proposed for one of perennial problem, "How should we understand, creat and maintain our family culture?" by employing practial reasoning and teaching models such as "role play" and "classroom meeting".
