Encased melt technique was applied to measure the amount of the undercooling of the bulk Sn, Pb, In, Bi, Sb, and Al metals. Quartz glass and argon gas were used to remove potent heterogeneous nucleation sites of the mould walls. Despite of a relatively slow cooling rate and a Large bulk type metal, a quite large amount of the undercooling of the Sn, Bi, and Sb metals was showed. Also, the undercooling of the Al metal was increased by the change of the heterogeneous nucleation site. The effects of the nucleation sites and gas environment condition on the solidification were also studied.

외환위기 등 급격한 환경변화를 겪은 사회복지법인은 현행 보고위주의 예산제도에서 벗어나 효율적인 예산제도 운영에 대한 요구가 높아지고 있다. 본 연구에서는 자원의 효율적 배분을 도모할 수 있도록 현행 사회복지법인 예산제도의 개선방안을 제시하고자 한다. 본 연구에서는 첫째, 투입중심, 통제중심의 현행 품목별예산제도를 개선하여 중ㆍ장기적, 전략적 자원배분과 성과관리체계를 강화해야 하며, 둘째, 예산운영의 효율성을 높일 수 있도록 자율성과 책임성을 부여할 수 있도록 해야 하고, 셋째, 예산집행에 일관성을 유지할 수 있는 구제적인 지침이 마련되어야 하며, 넷째, 복식회계ㆍ발생주의 예산제도를 도입하고, 마지막으로 중ㆍ장기 전략적 자원배분이 가능한 예산프로세서 확립을 현행 사회복지법인의 예산제도 개선방안으로 제시하였다. 한국의 사회복지법인 실정에 맞는 예산제도의 마련을 위해서 본 연구를 확장하여 더 많은 연구가 이루어져야 한다.

Objectives This study is to investigate the related factors to contribute the metabolic syndrome according to Sasang Constitution. Methods Nine hundred twenty six persons out of 1774 persons, over 40 years old, participated in community-based cohort in Wonju City of South Korea from June 2006 to August 2009. The diagnosis of metabolic syndrome was carried out by NCEP-ATP III(National Cholesterol Education Program in Adult Treatment Panel III) and Asian Pacific Criteria for abdominal obesity. The related factors were checked using questionnaire and blood samples. Sasang Constitution was verified by a Sasang Constitution specialist using the results of PSSC(Phonetic System for Sasang Constitution), facial pictures and simplified Sasang Constitutional questionnaires. Metabolic syndrome incidence rate according to Sasang Constitution and binary logistic regression analysis were performed with SPSS 19.0. Results Metabolic syndrome incidence rate was 30.3% and the majority of newly categorized as metabolic syndrome was Taeeumin(40.7%). There were significant risk factors like systolic blood pressure, fasting blood sugar, triglyceride and female and a significant defense factor like HDL-cholesterol. In terms of constitutional view, there were significant risk factors like waist circumference, systolic blood pressure, triglyceride in Soyangin, female, waist circumference, systolic blood pressure, fasting blood sugar, triglyceride in Taeeumin, female, waist circumference, systolic blood pressure, triglyceride in Soeumin. And there was a significant defense factor like HDL-cholesterol in only Taeeumin. Conclusions Regimens on metabolic syndrome were considered to be changed according to Sasang Constitution. Taeeumin female and Soeumin female should be cautious of body weight and metabolic syndrome when elderly. There are more cautious risk factors in each constitution; systolic blood pressure and triglyceride in Soyangin and fasting blood sugar and serum lipids levels in Soeumin and Taeeumin.
