This study was carried out to investigate the prevalence of fascioliasis of slaughtered and farmed cattle in Gwangju area from February to November in 2007. A total of 1,000 cattle fecal samples were collected from slaughter houses (n=805) and farms (n=185). Twelve (1.2%) were found as positive cases with excretion of the egg of Fasciola spp in the fecal specimens, and 128 (12.8%) were positive in intestinal parasitism using the flotation and sedimentation procedures. The infection rate of fluke larvae from the slaughtered cattle at abattoirs in Gwangju was 0.75% (6 out of 805 heads). In histopathology, there were several liver lesions such as inflammation with infiltration of eosinophil, polymorphonuclear cells, mononuclear cells and multinucleated giant cells, proliferation of connective tissue, calcification and abscess formation.

Recently, passengers using public transport are concerned about the effects of COVID-19 and fine dust. Therefore, from February 2020 to February 2021, we investigated whether SARS-CoV-2 RNA was detected even after disinfection in 55 public transportation places visited by confirmed patients in Seoul. 34 air samples and 702 object surface samples were collected and tested with RT-PCR, one surface sample was positive. In addition, preemptive investigations were conducted in 22 subway trains that passengers were being on board at that time. 1,018 preemptive tests were performed, and all were negative. Although PM-2.5 is dangerous in itself, it can be a potential carrier of viruses. It seemed that a solution was needed as one line continuously exceeded the criteria of PM-2.5. Through this study, it is judged that cluster infection in public transportation can be prevented if efforts to reduce the concentration of fine dust, appropriate disinfection management, and personal disinfection such as wearing a mask in public transportations.

According to 'Metropolitan Traffic Network Plan' announced in 2001, radial railways which connect Seoul with satellite cities around Seoul appear gradually. And followed by this, social demand for circular metropolitan railways that can connect the radial railways horizontally is increasing. But existing plans about circular metropolitan railways has limits to propose only passing cities of the railways. If there is no detailed guideline for circular metropolitan railways, the each railway for circular line will be constructed individually and then it will be not effective circular railways totally. Additionally that railway project will be easily interrupted by popular complaints. Therefore "The basic plan for circular metropolitan railways" is needful to guide a right direction for circular metropolitan railways. In this paper, rough track diagram of 'node' station for circular metropolitan railways is proposed. It is essential part of the basic plan. If the track diagram of a node is publicized in advance and individually lines of circular metropolitan railways is enforced to followed it, all lines will has rich circular functionality. Finally, effective circular metropolitan railways can be built.

Berries are rich sources of phenolic compounds, which are known to have health-promoting effects. In this study, phenolic compounds of seven popularly consumed berries were analyzed by HPLC-ESI-MS/MS. In addition, 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical and nitrite scavenging activities were investigated for comparison of the biological activity of the berry extracts. Chlorogenic acid was the major phenolic acid, which had the highest content in aronia, followed by blueberry. The rutin and isoquercetin contents were the highest in mulberry, followed by aronia, black raspberry, and blueberry. The anthocyanin content was the highest in black raspberry. Aronia showed the highest DPPH free radical and nitrite scavenging activities with the highest contents of total phenolics and proanthocyanidins.
