Purpose - This research was to help distribution of Go Bags (Survival Bag or Disaster Supplies Kit), which are useful for disaster preparedness, by surveying precomposed Go Bag items in internet shopping malls. Research design, data, and methodology - We checked 15 items including food, water, first aid kit, radio, flashlight or candles, battery, lighter or matches, whistle, blanket, towel, toilet paper, personal sanitations, raincoat, can opener, disaster manual in Go Bags based on the recommendations by the Ministry of the Interior and Safety. The number of items and price, domestic product, accreditation were compared using a Chi-square test. The Pearson's R was also used to summarize the strength of the linear relationship between the number of items and price, sub-items. Results - Mean of the sub-items was 21, and mean of the items was 8. There was a statistically significant difference between the number of items size and the price level (p=.014). There was also a statistically significant difference between the number of items and sub-items (p<.001), and correlation coefficient was a positive linear relationship of .467. Conclusions - Only eight were sold in the internet shopping malls as a precomposed Go Bag items. Even the approved Go Bags had no difference in the number of items. Higher prices had a relatively greater number of items, and it had a positive correlation between the size of sub-items and items.

The strains of Salmonella othmarschen and Norovirus isolated from outbreak A, the funeral ceremonies incidents in Ouri-shi of Oyeonggido in, 2007, were subjected to genotyping by using PFGE and extraction of RNA by using RT-PCR. 24 Salmonella othmarschen were isolated from 37 cases (patients 12 cases, cookers 4 cases, foods 7cases, knife, kitchen board, dish towel 4 cases, etc) and PFGE patterns showed that 22 strains isolated from the same incident were almost of the same pattern and 2 strains exhibited 50% of the pattern. Antimicrobial susceptibility patterns were such that there were 22 case susceptibility patterns and 2 case resistance patterns (strain 4: AM, CF, CIP, NA, TE TIC and strain 13: CF, CZ). Norovirus G1 (1case), Norovirus G2 (7cases), Norovirus G1,G2 (1case) were detected by using RT-PCR. The fine typing ability and reliability of PFGE and BioNumerics are helpful for establishing out the foodborne pathogens of outbreaks.

This paper presents a new forward-viewing mono-camera based obstacle detection algorithm for mobile robots. The proposed method extracts the coarse location of an obstacle in an image using inverse perspective mapping technique from sequential images. In the next step, graph-cut based image labeling is conducted for estimating the exact obstacle boundary. The graph-cut based labeling algorithm labels the image pixels as either obstacle or floor as the final outcome. Experiments are performed to verify the obstacle detection performance of the developed algorithm in several examples, including a book, box, towel, and flower pot. The low illumination condition, low color contrast between floor and obstacle, and floor pattern cases are also tested.

Germination of sweet and super sweet corn is lower than normal corn due to the higher sugar and lower starch contents of kernels. Sweet corn seeds are easily deteriorated in the field under the unfavorable condition, therefore it is important to identify the optimal harvesting time for seed production. This trial was conducted to investigate the responses of germination percentage of shrunken-2(sh2), brittle(bt), sugary(su), and sugary enhancer(se) hybrids in relation to harvesting dates. Eight hybrids of four different gene sweet corns were harvested at 15, 20, 25, 30, 35, 40, 45, and 50 days after silking(DAS). Germination test was performed using paper towel method. Mean germination percentages across eight hybrids showed the highest value at 45 DAS. There were significant differences among genes and within gene for germination. Shrunken-2 hybrid Mecca was higher than su hybrids for germination, indicating that sh2 would not be poorer than su Late harvesting beyond the optimal harvesting date might not be desirable because of more lodging and ear rots. Theoretical optimal harvesting date estimated from the regression equation was 40.9 DAS, however, practical date for harvesting would be a few days later than the estimated date if seedling vigor might be considered. Kernel dry weight per ear showed similar response to germination. Regression equation showed the highest kernel dry weight at 40.7 DAS. Significant correlations between kernel dry weight and germination were observed, impling that kernel dry matter accumulation would be an important factor for germination.

Studies were made on the relation of mastitis infection rate to the management and sanitations of dairy farms by examining 46 dairy herds. The results obtained were as follows: 1. The higher infection rate was observed in farms managed by employees than by owners, and in impoprted cattle than cattle horn in Korea. 2. Type of education and the period of experience of management were not correlated to the infection rate. 3. The infection rate was the highest in Summer and in cattle of 5~8 lactating age group. 4. It was observed that the amount of water supply, time of cleaning stall, frequency of disinfection, the method of using cleaning towel and the method of milking were correlated to the infection rate.

To evaluate the possible route of intrafamilial transmission among carriers of hepatitis B surface antigen ($HB_sAg$), epidemiologic and serologic data were obtained on 107 household contacts of 35 carriers of HBsAg and on 71 household contacts of 25 controls who were negative for serologic markers of hepatitis B virus. The HBsAg prevalence was 26.5% among the contacts of carriers compared to 0.0% among the contacts of controls. And the combined prevalence for all hepatitis markers was 48.5% among the contacts of carriers compared to 26.0% among the contacts of controls(p<0.05). Especially the offspring of carriers showed significantly higher risk in the combined prevalence for all hepatitis markers (p<0.05). There were no significant relationship between HBV infection and past history like acupuncture, transfusion, operation and tattooed. Factors associated with the risk of intrafamilial transmission of HBV were not found in the sharing of household articles such as razor, towel, drinking glass, nail clippers, toothbrush and tableware.

This study was peformed to characterize the physiological signal prior to develop an algorithm which quantifies EEGs evoked by tactile stimulation. The experiment was devised with four experimental conditions, which were control and two levels of pressures in tactile sensation. Twenty subjects were used to obtain EEGs while applying tactile stimulation using two types of textiles, soft towel and sand paper, to the right hand of each subject. EEGs were acquired for 20 seconds, and each trial was repeated five times randomly at the different levels of stimulus intensities. The index, $S_{n}$, was obtained by calculating the ratio of energy distribution in the time-frequency plot for each scored psychological state of the subject. The results showed that dominant aspects of the EEG signals have their maximal frequencies concentrated at a lower ranges for the resting and pleasant state, while the spectral energies were distributed to higher frequency ranges when subjects experience an unpleasant emotion.

연구목적: 최근 전기레인지의 사용증가와 더불어 화재도 증가하고 있다. 전기레인지 중 대표적인 인덕션과 하이라이트 방식에 대해 구조 및 작동방법을 알아보고 화재위험성을 살펴보고자 하였다. 연구방법: 두 방식에 대하여 연소실험, 전열실험, 발화실험 등을 실시하였다. 연구결과: 하이라이트 전기레인지는 키친타월이 2분 후 연소되었고, 조리를 마친 후 잔열이 식는데 약 25분이 소요되며, 니크롬선의 붉은 기운이 3~4분 만에 사라지고 불꽃이 보이지 않았다. 결론: 실험 결과 하이라이트 방식은 화상 및 화재 위험성이 존재하며, 특히 상판에 균열이 있을 경우 화재 및 폭발의 위험성이 있음을 알 수 있었다.
