증류주에서 중요한 향미 물질인 에스테르 생성과정을 알아보기 위하여 발효완료 술덧에 알코올과 함께 존재하는 초산, 젖산, 구연산 같은 유기산의 종류별, pH별, 증류 온도별로 에스테르 생성 과정을 실험하였다. 유기산의 종류별 실험에서 생성 에스테르량은 ethyl acetate가 기주에 비해 최고 2,890%, ethyl lactate가 최고 6,410% 및 iso-amyl acetate가 최고 52% 증가하였다. 에스테르화시 pH는 중요한 요인이며, 초산첨가 에스테르화 증류액의 ethyl acetate의 경우 pH 3.0이 pH 4.5보다 1,092% 증가하였다. 에스테르화 증류온도는 초산첨가 에스테르화 가압 (약 1.9 기압) 증류액은 상압 (1기압) 증류액보다 ethyl acetate 생성은 18% 증가하였고, iso amyl acetate 생성은 24% 감소하였고, 젖산 첨가 에스테르화 가압 증류액은 상압 증류액보다 ethyl-lactate 생성이 33% 증가하였다. 에스테르화 증류시간은 pH 3.0에서는 ethyl acetate 생성은 반응시간 240분으로 충분하고, ethyl lactate 생성은 30분 이상 긴 반응 시간이 필요하였다. 결론적으로 증류주 제조에 있어서 2차 증류시 1차 증류액에 유기산을 첨가하여 증류하면 에스테르량이 증가한 2차 증류액을 얻을 수 있었다. The esterification of alcohols with acetic acid, lactic acid and citric acid was carried out in batch during the second distillation. Effect of various parameters, e.g. pH of reactant base spirit, temperature of distillation, time of distillation were studied. The parameter of distillation temperature was modified by atmospheric distillation and pressure distillation. The pressure (1.9 atm.) distillation was used in order to react and distill at high temperature. Compared with the base spirit concentration, ethyl acetate, ethyl lactate and iso-amyl acetate in esterification distillate increased by 2,890%, 6,410% and 52% , respectively. Major factors of the esterification with organic acids in distilled spirit making were molecular weight of the organic acid and pH of reactant base spirit.

Efficient Unlinkable Secret Handshakes for Anonymous Communications

Eun-Kyung Ryu1,Kee-Young Yoo,Keum-Sook Ha 보안공학연구지원센터(JSE) 2010 보안공학연구논문지 Vol.7 No.6

The technique of secret handshake is used as a fundamental building block for anonymous peer-to-peer communications over untrusted networks. However, the fact that most existing schemes fail to meet unlinkability causes the use of schemes to limit for practical use. In this paper, we provide new constructions for unlinkable secret handshake, allowing arbitrary two communication parties with the same role in either one single group or multiple groups to privately authenticate each other. Compared to previous works, our techniques have much better performance in terms of both computational and communication cost, while they obtain good security results.

This purposes of this study were to assess the state of current administration and program contents in early childhood institutes. Using APECP(Assessnt Profile for Early Childhood Programs), assesment data were gathered from 27 apprentices in child care centers and 6 apprentices in Kindergarten in Cheongju. Descriptive statistics and Mann-Whitney test were used to analyze data. The result were as follows : (1) The distribution of percentile rate in administration was from 55% to 78%, and the area of Program Development scored the lowest. The assessments for Kindergarten were higher than those of child care center in the areas of Physical Facility, Food Service, and Program Management. (2) As for the program contents, percentile rate was from 62% to 80%, and generally the assessments for Kindergarten were higher than those of child care center. It appears that the certification and assessment system for ealry childhood institutions should be supervised more strongly in order to improve the qulaity of those institutions.
