  • In order to find a way to reduce histamine formation when storing salted mackerel at home, a series of experiments were carried to monitor the time-related changes of histamine content, total aerobic bacteria and coliform quality of mackerel marketed in Incheon by the type of storage containers (clean, zipper and vacuum bag) during storage at $4^{\circ}C$, $24^{\circ}C$ and $-20^{\circ}C$ for 10 days. Histamine formation was continuously increased with passing time during storage at $4^{\circ}C$, whereas it was decreased after 3 days during storage at $24^{\circ}C$. The initial value of histamine was maintained during storage at $-20^{\circ}C$ for 10 days. During storage at $4^{\circ}C$, total aerobic bacteria and coliform showed a tendency to increased rapidly till 3day and then decreased gradually. The formation of histamine was increased in the order of vacuum bag$4^{\circ}C$.

  • This study was to examine the effects of insurance coverage on the utilization of public health institutions and to identify the factors associated with the utilization. The data were obtained from household interview surveys conducted twice in Hwachun Gun, Kangwon Do. The time period covered in the first survey was December $17{\sim}31$, 1987, before the implementation of regional medical insurance for the self-employed, and that of the second survey was January 28 $\sim$ Febuary 11, 1990, after its implementation. Major findings emerged from the analysis can be summarized as follows (1) Medical care utilization of rural people markedly increased after they were covered by medical insurance. The insurance coverage increased the utilization of public health institutions as well, and this increase was mainly attributable to the utilization by chronically ill patients. (2) Between 1987 and 1990, the proportion of the utilization of public health institutions over whole medical care utilization decreased. But the proportion increased for chronically ill patients covered by regional medical insurance during the same time span. (3) The results of logistic regression suggested that the rural self-employed utilized public health institutions at an increased rate after they were covered by medical insurance. It was also indicated that the increase resulted from the utilization by chronically ill patients. (4) The relative importance of public health institutions for rural medical care decreased after the implementation of regional medical insurance. But considering that the utilization of public health institutions by chronically ill patients increased after insurance coverage, attention should be directed to improving the capability of public health institutions to control chronic degenerative diseases.

  • Polymorphisms in miRNA binding sites have been shown to affect miRNA binding to target genes, resulting in differential mRNA and protein expression and susceptibility to common diseases. Our purpose was to predict SNPs (single nucleotide polymorphisms) within miRNA binding sites of inflammatory genes in relation to gastric cancer. A complete list of SNPs in the 3'UTR regions of all inflammatory genes associated with gastric cancer was obtained from Pubmed. miRNA target prediction databases (MirSNP, Targetscan Human 6.2, PolymiRTS 3.0, miRNASNP 2.0, and Patrocles) were used to predict miRNA target sites. There were 99 SNPs with MAF>0.05 within the miRNA binding sites of 41 genes among 72 inflammation-related genes associated with gastric cancer. NF-${\kappa}B$ and JAK-STAT are the two most important signaling pathways. 47 SNPs of 25 genes with 95 miRNAs were predicted. CCL2 and IL1F5 were found to be the shared target genes of hsa-miRNA-624-3p. Bioinformatic methods could identify a set of SNPs within miRNA binding sites of inflammatory genes, and provide data and direction for subsequent functional verification research.

  • To evaluate the potential risk associated with zoonotic ascarid eggs in educational facilities and public playground in Seoul city, the sand samples collected from April to December in 2011 were examined with a fecal flotation method. Of 5,066 sand samples from 1,367 playgrounds tested, 12 sands from 12 places (0.88%) had ascarid eggs. Sand samples in educational facilities were more contaminated (10/870, 1.15%) with the parasite eggs than those of public playground area (2/497, 0.4%). Fisher's exact tests were used to make pairwise comparisons between which locations were more or less similar with regard to levels of contamination. We didn't find significantly different from one another. Most ascarid eggs detected were found in the Spring. Through this study, we hope to raise awareness of contamination of playgrounds by potentially infectious ascarid ova.
