This research was carried out to find the mordant effect of Chestnut's inner skin on the cow leather dyed by Turmeric powder. The best proper mordanting conditions were examined by changing mordant method, concentration, temperature, bath ratio, time, and repetition. Also dyeability and surface color changes were evaluated by various mordanting methods. The optimum mordanting conditions of chestnut's inner skin extract on the cow leather were pre mordant, 80%, $50^{\circ}C$, 50:1, 40minutes, 4 repetition. The K/S values as a mordant were higher in pre mordant than post mordanting condition. Although the ${\Delta}E$ was slightly higher in post mordant than pre mordant, it was too small to find any means. The surface colors of all dyed cow leathers were yellow. Among light, dry cleaning, and abrasion fastnesses, only light fastness was increased one degree, others were same degrees.

This research was carried out to find the dyeabilities and mordants effects of cow leather dyed with Lac powder. They were examined by changing dye concentration, dyeing temperature, bath ratio, dyeing time, and dyeing repetition. And K/S values and surface color changes were evaluated by various mordanting conditions. The optimum dyeing conditions of the cow leather dyed with Lac powder were 30%, $40^{\circ}C$, 30:1, 30minutes, and 4 repetitions. The K/S values were higher in post mordant than pre mordanting condition. The surface colors of dyed cow leathers were R and RP. The dye fastnesses increased in post Cu and Fe mordanting, as decreased in gallnut and chestnut's skin conditions.

This was a study examining the fatliquoring of natural dyed cow skin with Coptis chinensis Franch. The K/S according to optimal dyeing condition, mordants and mordanting method was measured. And the surface, sections, tensile strength, elongation, stiffness and colorfastness according to post-dyeing fatliquoring were observed. The optimal conditions include 300%(o.w.f.), $50^{\circ}C$, 30 minites. Fe-simmordanting showed the highest dyeability. Coptis chinensis Franch showed a yellow color regardless of mordants and mordanting methods. Tensile strength and elongation increased in the case of simmordanting compared with untreated and the process of fatliquoring further increased. The softness significantly increased when fatliquored. Shrinkage was slightly reduced when dyed, but showed almost no change with fatliquoring. Lastly, color fastness increased overall with mordanting and partly increased with fatliquoring. The rubbing and light fastness were excellent Cu- mordanting, and drycleaning fastness also improved with Cr-mordanting.

Allergic disorders may be defined as the abnormal reactions to proteins. Cow milk is the first foreign protein which the human being would contact postnatally. Serveral studies suggested that this contact had certain effects on the development o allergic disorders with great controlversies. Seven hundred seventy eight students from middle class in Seoul, aged 6 to 17 wears, were surveyed to delineate the relationshpis between the cow's milk contacts in infancy and the subsequent development of allergic disorders in Koran population. Questionaire were included the nursing patterns in infancy, the past medical history of asthma or wheezy bronchitis and the presence of infantile eczema. Skin tests to three common resporatory allergens in Korea(house dust, house dust mite; D. farinae, D. ptoeronssinus) were performed. The positivity was determined by the wheal size larger than that to histamine. 70.2% of whole mateials was fed by breast milk, 13.1% by cow's milk and 16.7% by mixed nutsing. From the obsevation of nursing patterns by (table 2), we find that the number of breast milk group has been decreasing in 1970's. 10.1% of breast milk group(BMG) had wheezy bronchitis, 8.8% of cow's milk group(CMG) and 11.5% of mixed nursing group(MNG). Infantile eczema history was positive in 27.8% of BMG, in 26.5% of CMG and in 29% of MNG. Skin test positivity was 23.8% in BMG, 25.5% in CMG and 26.2% in MNG. There prevalences of allergic disorders in each nursing group did not reveal any statistically significant differences. In conclusion, nursing patterns in infancy do not seem to have certain effects on the development of allergic disorders such as infantile eczema. wheezv bronchitis or skin test positivity.

Purpose: The Cow's Milk-related Symptom Score (CoMiSS^TM), which considers crying, regurgitation, stools, skin and respiratory symptoms, was developed as an awareness tool for evaluating cow's milk-related symptoms. The scoring ranges from 0 to 33. A score ≥12 was proposed as being likely cow's milk-related and suggestive of allergy to cow's milk. This study aimed to determine the age-related CoMiSS^TM values in presumed healthy infants in Poland. Methods: This was a cross-sectional study conducted in well-child clinics in two locations. Parents of the presumed healthy infants aged ≤6 months were approached during a routine checkup/vaccination visit. The exclusion criteria were as follows: presence of acute or chronic diseases, preterm delivery, treatment with therapeutic formula, and use of any food supplements (except vitamins) or medications. Results: Data from 226 infants were obtained (median age [Q1-Q3], 4 months [3-4]). The overall median (Q1-Q3) and mean (standard deviation) CoMiSS^TM values were 4 (2-7) and 4.7 (3.5), respectively. The 95th percentile was 11. Scores on some, albeit not all, components of the CoMiSS^TM significantly differed between age groups (crying, stools) or feeding type groups (stools and skin symptoms). Eleven children (4.9%) scored ≥12. Conclusion: This study adds to earlier age-related CoMiSS^TM data by providing CoMiSS^TM values in presumed healthy infants in Poland.

The outbreak of lumpy skin disease (LSD), caused by LSD virus (LSDV), in Jeollabuk-do was first confirmed at a Korean cattle farm in Buan-gun on October 24, 2023. Afterwards, thirteen cases (twelve cases in Gochang-gun and a case in Imsil-gun) were further confirmed, resulting in a total of fourteen cases over 25 days until November 17, 2023. Clinical examination were conducted on infected and co-habitting cattle from the LSD-affected farms with particular focus on the presence of nodules throughout the body such as head, neck, chest, femur, head, and perineum. As a results, abnormal clinical signs were observed in fifteen cows: loss of appetite in six cows, high fever in three cows, eye mucosal nodules in a cow, nasal mucosal nodules in six cows, nodules on perineum in five cows, scrotum nodules in two cows, papillary nodules in a cow, and/or skin nodules in eleven cows. By the PCR methods, the common gene of capripox virus and/or the specific gene of LSDV were detected in 35 of the 69 cows tested this study. In the Farm1, capripox virus-specific gene, LSDV wild strain-specific gene, and LSDV vaccine strain-spcific gene were simultaneously detected in affected cows, indicating the cattle farm was affected by various strain of LSDV. As a result of combining clincal examination and PCR test, it was found that clinically and subclinically infeted cows coexist in the LSDV-infected farms. These finding in this study will be a great help in diagnosis and prevention of the LSD in Korean cattle farms.

In the present study, the incidence of bovine tubeculosis (bTB) and brucellosis in Hanwoo (Korean native cattle) and dairy cow in Gyeongsangnam-do was investigated for three years from 2020 to 2022. The incidence bTB tested by tuberculin skin test with purified protein derivative (PPD) and gamma interferon (γ-INF) test with a commercial enzyme-linked immunosorbent assay. From 2020 to 2022, the incidence of bTB showed a decreasing trend in Hanwoo, while an increasing trend in dairy cow. In the case of Brucellosis, the positive rates for Hanwooe gradually increased. However, no brucellosis was found in dairy cow from 2020 to 2022. The increase in the incidence of these diseases is presumed to be related the small scale and poor sanitation facilities of livestock farms in Gyeongsangnam-do, and easy access of wild animals. Therefore, in order to suppress the incidence of the diseases, it is necessary to the farm scale from small to large and to strengthen sanitary facilities on farms.

On a farm with 6 Korean beef cattle, an adult cow and a calf suddenly died while eating. At that time, hair was pressed upon the stanchion facilities where the adult cow was fed. Two dead cattle were submitted to the Animal and Plant Quarantine Agency for disease diagnosis. Grossly, the mouth of the adult cow was full of feed that had been eaten before death, and there was a foamy fluid in the calf's trachea. Both hemorrhages were observed in the muscles, as well as in the internal organs such as the liver, lungs, and heart. Ruminal mucosa was easily peeled off. Histopathologically, both muscles and internal organs showed severe hemorrhages. In particular, affected muscles were shown segmental and band-like patterns of myonecrosis, disappeared some myocytes, burned hair follicles, and irregular surface of skin. Severe hemorrhages of muscles and internal organs were consistent with previous reports. Easily separated mucosa of rumen and muscle lesions were very characteristic. We determined electrocution according to the pathological findings, laboratory results, and traces of accidents. This report will help to understand of pathological lesions of electrocution. Furthermore, this case suggests that the electrical wires and devices must be installed and handled carefully during the construction of the cowsheds care.
