식품 중 곰팡이 이물에 대한 연구를 위하여 식품 제조 및 유통/보관현장에서의 곰팡이 오염수준 및 주요 곰팡이류를 조사하였다. 측정은 식품유형별 총 9장소 (젓갈류, 식초류, 쌀류, 밀가루류, 냉동만두류, 면류, 과자류, 육가공류, 김치류)와 유통/보관현장 총 8장소(물류 창고)에서 진행하였고, 각 생산라인에서 부유곰팡이, 표면 곰팡이 오염도를 조사하였다. 측정결과, 육가공류 생산현장에서 부유곰팡이 오염도가 가장 높게 측정되었으며, 김치류 생산현장에서의 부유곰팡이 오염도가 가장 낮게 측정되었다. 설비 및 벽면에서의 표면 곰팡이 오염도의 경우, 식품 제조 및 유통/보관 현장에 관계없이 거의 검출되지 않았다. 현장에서 검출된 주요곰팡이를 조사한 결과, Penicillium sp., Aspergillus sp., Cladosporium sp., 종이 우점종 곰팡이로 조사되었다.

This study investigated the effects of changes to the pulsation factor of pulsed direct currents on wound healing. Patients with a pressure ulcer at a care hospital for the elderly were randomly divided into three groups: Group 1 involved the application of 100㎲ in pulse duration, 10 ㎳ in pulse period, 100 pps in a pulsation factor, 15 ㎃ in pulse amplitude, and polarity red+ by using pulsed direct currents; Group 2 involved a change of pulse period to 8 ms; and Group 3 received general wound management. Although there were no statistically significant differences in the changing stages of pressure ulcers among the groups, all the groups dropped in numerical stages. In the two groups to which pulsed direct currents were applied, there was a statistically significant reduction in the stages of pressure ulcers from the initial assessment to the 12-week assessment (p<.05). Even though there were no statistically significant differences in changes to the area of pressure ulcers among the groups, a statistically significant decrease was found in pulsed direct current group 2 whose pulse period was shortened (p<.05). There was no difference in the healing rate of pressure ulcers among the groups, but it made a numerical increase in pulsed direct current group 1 and group 2 and a numerical decrease in group 3. There were no significant differences in the characteristics of those who had a full recovery among the groups. Those findings indicate that pulsed direct currents have positive effects on the wound healing of patients with a pressure ulcer and that a treatment with pulsed direct currents whose pulsation factor is raised by reducing the pulse duration is especially effective.

"Juan1" is a new japonica rice variety of mid-late maturing, tolerance to lodging and adaptable to direct seeding which was developed by the rice breeding team of National Institute of Crop Science, RDA, in 2005. This variety is derived from a cross between Ilpumbyeo, a variety of good-eating quality and high yield, and SR18392-HB683-104. The Juanl has heading date of August 19 at ordinary planting in the middle plain. It has semi-erect plant type with culm length of about 80cm and tolerance to lodging. This variety shows susceptible to blast, bacterial blight, virus diseases and brown planthopper. The milled rice kernels of Juanl are translucent with non-glutinous endosperm, clear in chalkiness and medium short grain. It has also low amylose content of 18.8%, low gelatinization temperature and good palatability. The average milled rice yield of this variety was 5.68 MT/ha at ordinary planting in local adaptability test for three years from 2003 to 2005. Juan! would be highly adaptable to middle plain and mid-eastern coastal region of Korea.

"Samkwangbyeo" is a new japonica rice variety developed and registered by the rice breeding team of National Institute of Crop Science, RDA in 2003, which was derived from a cross between good quality, high yielding line Suweon361 and a disease resistant line Milyangl01. This variety has about 129 days duration from seeding to heading in central lowland and mid-mountainous areas. It is about 87 cm in culm length and moderately tolerant to lodging. It has also erect pubescent leaf blade and slightly tough culm with good canopy architecture. Samkwangbyeo has the same number of tillers per hill and spikelets per panicle as those of Ilpumbyeo. It shows less sensitivity to premature heading by lately transplanting of 50-day old seedlings. It is slightly less tolerant to cold stress in terms of both heading delay and spikelet fertility than those of Ilpumbyeo. It shows delayed leaf senescence and considerable tolerance to viviparous germination at ripening stage. It shows moderate resistance to leaf blast, bacterial blight, and stripe virus, but susceptibility to insect pests. The milled rice of Samkwangbyeo exhibits translucent, relatively clear non-glutinous endosperm and medium short grain. It has similar amylose content of 18.3% and similar gelatinization temperature, and good palatability of cooked rice compared to Ilpumbyeo. The milled rice yield of Samkwangbyeo is about 5.69 MT/ha at ordinary culture in local adaptability test for three years. Samkwangbyeo would be highly adaptable to central lowland and mid-southern mountainous areas of Korea.

“Yeonganbyeo”, a new japonica rice variety (Oryza sativa L.), is a mid- maturing ecotype with high lysine content in kernels that was developed by the rice breeding team of National Yeongnam Agricultural Experiment Station (NYAES) in 2001 and released in 2002. This variety was originated from the single cross of Milyang 122/YR13616 Acp1 (in 1992/1993 winter) and was selected by means of a mixed method of bulk and pedigree breeding. The pedigree of “Yeonganbyeo” was YR15815-B-B-B-30 and designated in 1998 as “Milyang 164”. It has about 83cm in culm length with lodging tolerance. This variety is resistant to bacterial leaf blight (K1, K2, K3), stripe virus, and moderately resistant to leaf blast disease. Milled rice kernels of “Yeonganbyeo” has high lysine content of 4.31% (ratio of amino acid components in total protein), a clear translucent with non-glutinous endosperm and clear in chalkness and good at eating quality by pannel test. The yield potential of “Yeonganbyeo” in milled rice is about 5.45 MT/ha at ordinary fertilizer level of local adaptability test. This cultivar would be adaptable to the southern plain of Korea.
