Authors have selected a physiological bad breath patient( 62 years old, male ) among the bad breath outpatients who have visited the halitosis control clinic in Korea University Medical Center(KUMC). The patient visited the halitosis control clinic for his oral malodor control, 3 times from April to June in 2018, and in August the patient visited to KUMC malodor control clinic again for his assessment of his two months efforts. Getting the data about the patient's endeavor to get over his physiologic oral malodor and the estimation of the patient's satisfaction level at his oral malodor improvement by a questionnaire method, and the organoleptic level assessment by the dentist, then we could propose an estimation method of the physiologic oral malodor patient care prognosis.

The antimicrobial and antioxidant activities of grapefruit seed extract(GFSE), which was extracted with glycerine in the special schematic extraction apparatus, were investigated for handling and processing of fishery products. The effectivity of GFSE has been tried on sardine, mackerel and shrimp divided into six lots for each fishery product: control(no treatment) and five GFSE-treated samples. Samples were inoculated with Salmenella typhi, incubated for 24hrs at $30^{\circ}C$ in dextrose-tryptone broth medium and prepared for microbiological 8f chemical analysis and organoleptic assessment. The bacteriological analytical results with GFSE(250ppm) showed the reduction of $1.8\times10^6\to2.0\times10^4,\;1.9\times10^6\to1.8\times10^4$ and $1.6\times10^6\to2.7\times10^3$ in total bacterial count for sardine, mackerel and shrimp, respectively. The test results with GFSE(500ppm) showed a $100\%$ reduction of bacterial mackerel treated with GFSE(500ppm) was reduced to $1.1\times10^4$ and $9.0\times10^3$ respectively. Antioxidant effect of treatment with GFSE at 500ppm level for three products was significant. LSD test results on organoleptic parameter for the samples treated with various showed a significant influence on the appearance, odor and texture in which at concentration 500ppm level give the excellent scours compared to each control.
