  • The puropose of this study was to investigate the relationships between four aspects of clothing behavior ana marital adjustment. Marital adjustment was measured with the Spaniel's Marital Adjustment Scale. The questionnaire measuring clothing behavior consisted of items designed to assess dressing for self, dressing for others, self-concept regarding clothing and dependence in clothing. This questionnaire was selected and revised from inventories of such researchers as Pasnak, Sin, Lee, Park and Creekmore. This questionnaire was administered to 269 home makers in Seoul. Statistical analyses utilized in this study included correlation coefficients and $X^2$ test. The results were as followes: 1. Marital adjustment showed significant and positive relationships with dressing for self, dressing for others, ana self-concept regarding clothing. 2. Marital adjustment was negatively correlated to dependence in clothing.

  • 제올라이트에 포함된 feldspar와 illite의 불순광물을 공기분급 조작 의하여 정제하였다. 공기 분급된 제올라이트를 XRD로 분석한 결과 공기분급에 의하여 제올라이트와 불순광물을 분리 할 수 있었고, 공기 분급을 함으로서 불순광물이 감소된 것을 알 수 있었다. 또한, 공기 분급된 천연 제올라이트를 1N NaOH용액으로 100, 150, 200℃에서 17시간동안 수열처리한 결과 mordenite와 clinoptilolite에서 phillilsite와 analcime의 상변화를 얻을 수 있었다.

  • The adsorption performance of lead ion was studied using five zeolites (Na-P1, sodalite (SOD), analcime (ANA), nepheline hydrate (JBW), cancrinite (CAN)) synthesized from Jeju scoria. The adsorption performances of lead ion decreased in the order of Na-P1 > SOD > ANA > JBW > CAN. These results showed that the synthetic zeolite with a higher cationic exchange capacity showed a higher adsorption performance. The uptake of lead ion by synthetic zeolites were described by Freundlich model better than Langmuir model. The adsorption kinetics of lead ion by synthetic zeolites fitted the pseudo 2nd order kinetics better than pseudo 1st order kinetics. The effective diffusion coefficients of lead ion by synthetic zeolites were ten times higher than the zeolite A synthesized from coal fly ash.

  • The Santa Ana winds occur in Southern California during the September-May time frame, bringing low humidities across the area and strong winds at favored locations, which include some mountain gaps and on particular slopes. The exceptionally strong event of late October 2007, which sparked and/or spread numerous fires across the region, is compared to more recent events using a numerical model verified against a very dense, limited-area network (mesonet) that has been recently deployed in San Diego County. The focus is placed on the spatial and temporal structure of the winds within the lowest two kilometers above the ground within the mesonet, along with an attempt to gauge winds and gusts occurring during and after the onset of October 2007's Witch fire, which became one of the largest wildfires in California history.

  • The ermK gene from Bacillus lichenformis encodes an inducible rANA methylase that confers resistance to the macrolide-lincosamide-streptograminB antibiotics. The ermKmANA leader sequence has a total length of 357 nucleotides and encodes a 14-amino acid leader peptide together with its ribosome binding site. The secondary structure of erm leader RNA and a leader peptide have been reported as the elements that control expression. (omitted)
