This study is purposed to propose the basic model for calculation of the proper dwelling size, which is suitable to the conscious structure and form of the dwelling life of Korean, in planning the unit plan with a national housing-size apartment after this. It limits the factors which effect the dwelling size(Y) to general household characteristic of dweller and the activity of dwelling life. It clears the formula by regression model in the relation between these factors and dwelling size(Y). The results is follows ; 1) Y(X_(8)) = 1.55397(FF2)+1.08807(FF3)+0.62683(FF1)+18.89860, estimate ability of this formula comes into 23.6%. 2) Y(X_(8)) =0.99396(BB1)+0.43160(BB3)+0.33118(BB2)+0.34311, estimate ability of this formula comes into 28.5%. This study tries estimating the dwelling size(Y) not by the degree of satisfaction, but the aquirement marks of the exclusive dwelling-ratio in part. But the study is elementary in estimating the dwelling size(Y) and vary estimations are expected in the method of study. Thus the study is necessary to be achieved lastingly in the propriety of interpretation the value of dweller's degree of satisfaction.

Hypereosinophilic syndrome is characterized by persistent blood eosinophilia of 1,500/ul or more in the absence of known causes and multiorgan dysfunction by eosinophil-related tissue damage. In Korea, some cases of hypereosinophilic syndrome with hepatic involvement have been described with prolonged benign clinical courses. Most of them were diffuse or multifocal lesions in imaging studies, and a few case presenting as a single mass has been described. Here we report a case of hypereosinophilic syndrome with hepatic involvement in a 65-year-old man who presented with multifocal mass lesions. By abdominal US and CT scan, multiple, ill-defined nodules were detected in throughout the liver. Liver biopsy revealed severe eosinophilic hepatitis, suggestive of hypereosinophilic syndrome. Hepatic mass lesions improved after steroid administration for several weeks.

This study was conducted to compare the reproduction ability of the wild type boar and recombinant human erythropoietin (hEPO) transgenic boar semen. Ejaculated boar semen was analyzed by flow cytometry, Elisa and IVF methods. In experiment 1, flow cytometric analysis showed that the live sperm ratio of transgenic boar sperm significantly lower (P<0.05) than that of wild type boar after incubation at 20, 22, 24 and 26 hr. In experiment 2, the presence and levels of various cytokines (IL-6, IL-10 and TNF-α) to related animal reproduction in the seminal and blood plasma were examined using specific enzyme immunoassay. There was no significant difference between both groups. In experiment 3, the fertilizing capacity and developmental ability of both boar sperm were compared. The transgenic boar sperm had a significantly low capacity of penetration, sperm-zona binding, embryo development, and blastocyst formation compared to wild type sperm (P<0.05). These results suggest that transgenic boar sperm harboring hEPO gene has low sperm viability than wild type boar, and it is a reason to decrease of fertility and litter size.
