This study examined the hygiene management of ultrasound probes by examining the cleaning tools for hygiene management of ultrasound probes, the presence or absence of wearing glove as a personal protective equipment, and the awareness of ultrasound probe hygiene. Parts 154 questionnaire about people working in the ultrasound room were surveyed and analyzed. The single gel removal tool of the ultrasound probe was most frequently used with a 48.7% cotton towel, and for double gel removal tools, the first gel removal tool was 42.4% cotton towel and the second gel removal tool was used with 57.6% wet tissue. Antimicrobial wipes were the most commonly used drug and instrument used in ultrasound hygiene management at 58.4%. According to the survey of the presence or absence of wearing glove during ultrasound examination, 46.8% were found to be unworn. When examining the intracavity ultrasound, 30.9% of those who do not wear glove and 61.0% of hygiene awareness of ultrasound probes are 'normal'. According to age, ultrasound probe gel removal tool was not significant difference(p>0.05). According to the working organization and the working department, it was significant difference to wearing gloves during ultrasound examination(p<0.05). Therefore, in order to properly sanitize the ultrasound probe, it is considered that a guideline for hygiene management of the ultrasound probe that fits the situation in Korea is necessary, and it is considered that thorough hygiene management training for inspector is necessary for efficient hygiene management of the ultrasound probe.

This study was conducted to evaluate the microbiological contamination on commonly used hand towels in the child care centers and to investigate the toxin gene and toxin production ability of food-borne pathogens. A total of 22 commonly used hand towels including 7 for before use and 15 for during use were tested. The average number of total aerobic bacteria and fungi were 6.2 log CFU/100 $cm^2$ and 4.1 log CFU/100 $cm^2$. Coliform bacteria were detected in 4 out of 7 before used towels (57.1%) and all of during used towels (100%). These results showed that the sanitary conditions of hand towels in the child care centers should be improved promptly. Among the pathogenic bacteria, Staph. aureus and B. cereus without Salmonella spp. were detected in 5 (22.7%) and 11 (50.0%) out of 22 hand towels. All of Staphy. aureus isolated in this study did not possess any toxin genes and did not produce enterotoxin. The detection rate of hblC, hblD, and hblA toxin genes in B. cereus was 72.7, 72.7, and 54.5% respectively. The possession rate of nheA, nheB, and nheC toxin genes showed 81.8, 72.7, and 54.5% respectively. The cytK and entFM toxin genes were presented at 45.5 and 90.0% in B. cereus. The HBL was detected in 8 out of 11 B. cereus isolates (72.7%) and 5 B. cereus isolates produced NHE (45.5%). Ten out of eleven B. cereus isolates (90.9%) produced one or more enterotoxin such as HBL and NHE. From the results, using a private hand towel or paper towel is required to prevent the cross-contamination between commonly used hand towel and children's hands in the child care center.

목욕탕, 호텔과 같이 다량의 수건이 사용되는 곳은 빠르게 수건을 개기 위해서 수건을 접는 로봇을 사용한다. 그러나 기존의 수건을 접는 로봇은 사람이 수건을 일일이 일정한 형태대로 정렬을 해주어야 하고 복잡한 구조로 인해 부피가 크다는 단점이 존재한다. 본 연구에서는 기존의 수건 접는 로봇보다 구조가 간단하고 부피가 작으며, 임의로 투입된 수건을 자동으로 정렬하는 로봇을 개발하였다. 특히 랙과 피니언을 이용한 수직운동과 컨베이어 벨트의 수평운동을 이용한 수건 접기 방식을 통해 로봇의 부피를 획기적으로 줄일 수 있었다. 또한 영상처리 과정을 통해 수건의 각 꼭짓점의 좌표를 실시간으로 트래킹 하여 모든 수건 접기 과정을 자동화하였다. 본 연구의 결과로서 강체가 아닌 유동성을 가진 수건을 정렬하는 방법을 개발하였으므로 향후 연구를 통해 여러 가지 물체들을 정렬하는데 응용될 수 있을 것이라 기대된다.

타월은 소비자가 구매할 때 촉감을 중요시하므로 염색 후 가공 시 유연제를 사용한다. 그러나 반복 세탁 후에는 유연가공제의 탈착으로 초기의 유연성을 잃게 되고, 유연성 유지를 위해 후 가공시 유연제를 다량 사용할 경우 타월의 흡수성을 감소시키게 된다. 유연제는 이온성 별로 다양한 종류가 시판되고 있으나, 수중에서 음으로 하전된 면섬유와 이온결합이 가능한 양이온성 유연제가 가장 많이 사용되고 있다. 양이온성 유연제는 4급 암모늄 화합물로 항균효과도 부수적으로 타월에 부여한다. 본 연구에서는 반응성기를 도입한 양이온성 유연제를 합성하여 시판 유연제와 사용량에 따른 유연효과, 내세탁성을 비교하였으며, 또한 염색 후 유연가공한 타월의 색상변화도 조사하였다. 합성한 양이온성 유연제는 친수성의 특성도 유지하면서, 5회 세척 후에도 개선된 유연효과를 나타내었다.

The risks of sanitary indicative bacteria, heavy metals and chlorinated derivatives in 94 cases of sanitary wet towels used in food services (39 from sanitary wet towel treatment business, 55 from food services) were assessed in the present study. Lead was detected in the range of N.D.~0.41 mg/kg (75 cases were not detected), N.D.~0.25 mg/kg of arsenic (93 cases were not detected), N.D.~0.01 mg/kg of cadmium (7 cases were lower than limit of quantitation; 87 cases were not detected), 0.003 mg/kg ~ 0.09 mg/kg of mercury. And chromium (VI) was not detected from all samples. The level of lead was the highest among the tested heavy metals, and the highest concentration of lead was 0.41 mg/kg. However, it was only 2.1% of legal limit (less than 20 mg/kg). The average moisture content of the samples was 61.9% (50.0% ~ 77.0%) and it showed no relevance to the detection of bacterial counts. Escherichia coli was not detected. Bacterial counts were detected 43 cases and among them, 24 cases were exceeded the legal limit. It was verified that the packaging conditions of sanitary wet towel (whether it is packed by a piece or not and sealed or not) are critical factors to cause the germ contamination and cross contamination in the wet towels. The chlorinated derivatives (chlorites and chlorates) were detected in 17 (19.3%) out of 88 cases. The results would be used as preliminary information to establish the programs of "Safety education for manufacturers and public policy of safety".

To investigate the hormetic effects of the low dose ${\gamma}-ray$ radiation on the germination rate, Welsh onion (Allium fistulosum L. cv. Eunchun and cv. Sukchangwoidae) seeds were irradiated at the dose of $0.5\;{\sim}24.0$ Gy with the ${\gamma}-ray$ radiation (Co-60). The germination rate of 'Eunchun' cultivar increased about 10% in the low dose ${\gamma}-ray$ irradiation group compared with that of the control. In the 'Sukchangwoidae' cultivar, the germination rate of the 4 Gy irradiation group increased 40% more than that of the control. Broadly, it seemed that the hormetic effects of the low-dose ${\gamma}-ray$ radiation were taken more promisingly in the uncultivated soil than in the fertile soil. The germination rate from the paper towel and filter paper based cultivation increased 10% and 16% more, respectively, in the 1 Gy irradiation group than that in the control group. And the electric conductivities of the above groups supposed to be taken hormetic effects of the ${\gamma}-ray$ radiation were lower than those of the control group. From the above results, it is suggested that the low dose ${\gamma}-ray$ radiation ranged from 1 Gy to 10 Gy could have the hormetic effects on the germination rate related characters in Welsh onion seeds.
