This study was attempted to survey on the prevalence of heart-worm infection among 253 dogs (male 167, female 86) on the 16 breeding farms in southern Gyeongnam area in May to December 2007. The results obtained from this experiment were summarized as follows; 1. Fifty seven (22.5%) of the 253 examined dogs were heartworms antigen positive, while twenty five dogs were Microfilaria positive by the modified Knott`s method. 2. The regional infection rates were of Tongyeong (25%) and Goseong (21%), and on the breeding environment aspects, infection rates were rural area farms lower than urban area farms. 3. The sexual infection rates were observed female (26/86, 30.2%) higher than male (31/167,18.6%). 4. The infection rates in breeding size of farms were ?20 head, 20~50 head and ¤50 head were 31% (11/35), 26% (35/135) and 13% (11/82), respectively. 5. The infection rates of heartworm in examined dogs at the age of ?2, 2~4 and ¤5 were 10.7% (8/75), 26% (40/154) and 37.5% (9/24), respectively. 6. In the microfillaria infected 25 dogs, identified Dirofilaria immitis of 21 (84%) using PCR. 7. Dogs infected with heartworm were increased in number of eosinophil.

The present study was conducted to investigate the epidemiological characteristics such as isolation rate and antimicrobial drug susceptibility of etiological agents. The specimens (stool or intestine) were collected from 319 calves with clinical diarrhea from 195 farms in Gyeongnam south area (Gosung, Tongyung, Hadong) from June 2005 to August 2006. The isolation rate of Salmonella spp was higher in summer (8.4%) than in winter (4.8%) and the average was 7.2% (23/319 head). Some of Salmonella spp isolated were resistant to penicillin, oxytetracycline, tetracycline, and cephalexin (>90%), but some of them were suscep-tible to norfloxacin, ciprofloxacin, sulfamethoxazole/trimethoprim and amikacin(>30%). There was no statistical difference in the isolation rate of Eimeria spp between summer(48.9%) and winter(42.3%). For the evaluation of infection level of Eimeria spp oocyst per gram of feces(OPG) was examined, and severe, moderate and light infection level were 11.9%, 12.5% and 22.3%, respectively. In the isolation rates of Eimeria spp the calves under 19 days was lowerthan those over 60 days, but there was not different among herd size.

Among calves` diseases, digestive diseases most frequently occur in Korea, and especially viral diarrhea is one of the most important diseases. This study was conducted to get some basic information for the control of the viral diarrhea in calves. The samples were obtained from 319 calves with clinical diarrhea from 195 farms in Gyeongnam south area (Gosung, Tongyung, Hadong) from June 2005 to August 2006. Viral detection was examined by polymerase chain reaction (PCR). Etiological viruses were detected from 171(53.6%) of 319 calves, and bovine rotavirus (BRV) were 130 (40.8%) and bovine viral diarrhea virus (BVDV) 41 (12.9%), and no coronavirus was confirmed. Statistical difference was found in BRV detection between summer (32.6%) and winter (57.7%). However there was no seasonal difference in BVDV. In detection rate of the calves under 19days, BRV was highest (55.1%), but BVDV lowest (5.1%). No big difference was in rate among herd size. However, BRV was lowest (26.8%) in the group over 51 heads, but BVDV was highest (19.5%) in the same.
STS 436L 강의 성형성에 미치는 (Ti + Nb) 복합첨가의 영향

The effects of alloying elements(Ti, Nb and Ti+Nb) on the formability, mechanical and ridging properties of low C, N-18.5%Cr-1wt%Mo ferritic stainless steels have been investigated. The formability and ridging properties of cold rolled and annealed steels were effectively improved by addition of Ti and Nb together, 0.05∼0.1 wt% Ti and 0.2 ∼0.3% wt% Nb. The larger the amount of the Nb addition, the better results were achieved. The average r-value of the steel was the largest with the addition of (Ti+Nb) in the range of (Ti+Nb)/(C+N)=12∼20.
경북 동해안 지역 식생활 문화에 관한 연구(1) : 일상식과 특별식 for Normal and Particular Folk Meals

The present study was surveyed for the normal meal and particular folk meal in east cot area in Kyungpook province, Pohang, Youngduk, and Uljin areas. The results are as below: Most subjects for surveying were 30-40 years old and permanent residents in those areas. For the normal meal, the boiled rice was the top main dishes among 18 main dishes. The folloing upper five main dishes were boiled bean rice, boiled barley rice, boiled miscellaneous cereals rice, noodles, and Bbimbab (miced rice with cooked various vegetables and meats). Less frequent main dishes were raw fish Bbimbab and the various fish soups etc. The two upper side dishes, out of 17 surveyed ones, were kimchi and soybean paste soup. Twelve dishes(about 70%) out of 17 side dishes, the loach soup, the marinated and fermented raw fishes (fish Sikhae'), the baked mackerel, the pickled fishes, the friedsardine, the green seaweed, and the quid, etc. were made from the sea products. For the particular folk meal, about 30 kinds of the specific folk food items of this area were surveyed: Gudungchi' Sikhae', which was made with seaweed, out of the 11 kinds of fish Sikhae', raw fish(Whae') in water, Sigumjang', a salty agar, a steamed seaweed which was covered with the flour or bean power the various kinds of fish soups, the various kinds of fish stews were the particular folk side dishes in these areas. The dietary habit in these east coast areas were affected by the various sea food products, the fishes and the seaweeds, which were acquired easily through four season in these area.
