The purposes of this study was to analyze the characteristics of national races' costumes in Chinese contemporary costumes. For the purpose, this researcher concentrated on the relations between national races' costumes and Chinese contemporary costumes and discuss systematically depending on references such as fashion magazines, picture albums, and historical records. The results of study were as follows: First, the formation of fashion has been influenced by Man, Uighur, and Choson races. For example, Qipao, the tight style of Man race's fashion, Uighur race's bell style sleeve and cyclic skirt are applied to women's modern fashion. Second, weaving, printing, and embroidery technique of a minority race developed more than Han race, so applied still. Recently, Chinese contemporary costumes accepted the weaving technique of Miao and Uighur race through publicizing of a minority culture. Third, a national race's costumes are famous with splendid design and applied to modern fashion directly. They are commonly made to hair pin, necklace, earing, bracelet and so on. Recently, styles from a national race's costumes and old style are becoming popular to Chinese and it's easier to found such a fashion in market.

The autonomic regulation of heart rate (HR) is an indicator of the body's ability to adapt to an exercise stimulus. However, there are no reports on this topic in relation to Jeju horses used for racing. The aim of this study was to analyze the HR responses of Jeju horses during race trials and to investigate the correlation between HR and performance in these horses. HR data were collected from 17 healthy 2- to 7-year-old Jeju horses wearing HR monitors during race trials. Pearson correlation coefficients was used to determine the significance of the association between the race trial time and HR. A significant inverse correlation was observed between the race trial time (performance) and both the maximal HR (HRmax, r = -0.69, p < 0.01) and HR reserve (HRR) (HRmax - average HR during the warm-up period, r = -0.63, p < 0.01) and between the HRR and HRmax (r = 0.73, p < 0.01). Horses with a lower average HR during the warm-up period and higher heart rates during the trial achieved faster race trial times. This study reports the first HR measurements in Jeju horses during race trials, providing new insights into the HR response of this breed to exercise. The use of a noninvasive remote HR monitor system allowed assessment of exercise responses in the field, and the results suggest that both the HRR during warm-up period and HRmax may be useful performance indicators in Jeju horses.

Recently, the horse racing industry in Korea has developed rapidly with good betting turnover. One of the most important factors in enhancing the performance of racehorses is the study of equine exercise physiology. This study was performed to analyze the results of pre-race blood test on race day and evaluate its correlation with the race performance in Thoroughbred racehorses. Twenty-one, healthy 3- to 6-year-old Thoroughbred horses were used to collect blood samples and hematological and biochemical measurements were performed. Results were analyzed to identify its correlation with racing performance. Analysis of hematological profile of pre-race blood of the racehorses revealed that red blood cell indices including RBC, Hb, and PCV levels were elevated. Additionally, levels of AP, AST, and GGT were also elevated in pre-race blood of horses on race day. RBC, Hb, and PCV levels of high performance racehorses were significantly lower than those of low class racehorses. Moreover, the analysis of correlation between blood test results and racing ability-related categories have shown negative correlations for rating, placing strike rate, prize money per race, RBC, Hb, and PCV and positive correlations for G3F and PCV. Additionally, AST value was positively correlated to prize money per race. Thus, the results of this study show that red blood cell indices and AST are good parameters for evaluating racing performance of horses before the race.

The racehorses that under arthroscopic surgery due to be injured his limbs were studied during exercise or training at Busan Race Park from 2005 to 2010. Rate of arthroscopic surgical treatments was 1.4% (63/4,642). Affected bones were radius, radial carpal bone, third carpal bone, proximal phalanx, third metacarpal bone, femur, tibia, proximal sesamoid bone and intermediate carpal bone. The lesions were fracture, chip fracture, slap fracture, osteochonrosis, and osteochondrotitis dissencans. Number of patients under arthroscopic surgery were 63. Success horses of returned to racetrack or tried to return to racetrack were 58, and 5 horses were in training or resting at the time of publication. Success horses of returned to their previous use in the patients were 49 horses (84.4%) and no returned to the racetrack were 9 horses (15.6%) in 58 horses.

The ratio of form and character in the text generation of silkworms which were double copulated between home race copulation and hetero race copulation in crossing with two males of different races for female(double crossing) are different according to the copulating time, copulating order and sperm activities. But the general tendencies are as follows; 1. During two hour's double copulation, sufficiently ejaculating time, the fertilization percentage of hetero lace copulation are higher than that of homo race, but in case of double copulation with plain and normal marked silkworms showed opposite results. The fertilization percentage of homo race copulation are equal or higher compare with that of hetero race copulation. 2. The form and character of the next generation were largely effected by copulating order, so the primary copulating moths are more effected in the next generation than the secondary moths. 3. The active sperms were more fertilized than non-active sperms in the double copulation.

Clubroot is one of the most economically important diseases of the Brassicaceae family. Clubroot disease is caused by the obligate parasite Plasmodiophora brassicae, which is difficult to study because it is nonculturable in the laboratory and its races are genetically variable worldwide. In Korea, there are at least five races that belongs to four pathotype groups. A recent study conducted in Korea attempted to develop molecular markers based on ribosomal DNA polymorphism to detect P. brassicae isolates, but none of those markers was either race-specific or pathotype-specific. Our current study aimed to develop race- and isolate-specific markers by exploiting genomic sequence variations. A total of 119 markers were developed based on unique variation exists in genomic sequences of each of the races. Only 12 markers were able to detect P. brassicae strains of each isolate or race. Ycheon14 markers was specific to isolates of race 2, Yeoncheon and Hoengseong. Ycheon9 and Ycheon10 markers were specific to Yeoncheon isolate (race 2, pathotype 3), ZJ1-3, ZJ1-4 and ZJ1-5 markers were specific to Haenam2 (race 4) isolate, ZJ1-35, ZJ1-40, ZJ1-41 and ZJ1-49 markers were specific to Hoengseong isolate and ZJ1-56 and ZJ1-64 markers were specific to Pyeongchang isolate (race 4, pathotype 3). The PCR-based sequence characterized amplified region (SCAR) markers developed in this study are able to detect five Korean isolates of P. brassicae. These markers can be utilized in identifying four Korean P. brassicae isolates from different regions. Additional effort is required to develop race- and isolate-specific markers for the remaining Korean isolates.

Xanthomonas campestris pv. campestris (Xcc) is a plant pathogen of Brassica crops that causes black rot disease throughout the world. At present, 11 physiological races of Xcc (races 1-11) have been reported. The conventional method of using differential cultivars for Xcc race detection is not accurate and it is laborious and time-consuming. Therefore, the development of specific molecular markers has been used as a substitute tool because it offers an accurate and reliable result, particularly a quick diagnosis of Xcc races. Previously, our laboratory has successfully developed race-specific molecular markers for Xcc races 1-6. In this study, specific molecular markers to identify Xcc race 7 have been developed. In the course of study, whole genome sequences of several Xcc races, X. campestris pv. incanae, X. campestris pv. raphani, and X. campestris pv. vesicatoria were aligned to identify variable regions like sequence-characterized amplified regions and insertions and deletions specific to race 7. Primer pairs were designed targeting these regions and validated against 22 samples. The polymerase chain reaction analysis revealed that three primer pairs specifically amplified the DNA fragment corresponding to race 7. The obtained finding clearly demonstrates the efficiency of the newly developed markers in accurately detecting Xcc race 7 among the other races. These results indicated that the newly developed marker can successfully and rapidly detect Xcc race 7 from other races. This study represents the first report on the successful development of specific molecular markers for Xcc race 7.

Severe Fusarium wilt of tomato was observed in greenhouses in Sedo, chungnam and Sandae, Kyeongbuk from march to May 1993. Among the 20 isolates of Fusarium oxysporum isolated from wilted tomato plants and their rhisoplane or rhizosphere, 18 isolates were pathogenic to tomato. All of the pathogenic isolates were identified as F. oxysporum f. sp. lycopersici; they were pathogenic only to tomato and not pathogenic to red pepper, potato and egg-plant. The isolates of F. oxysporum f. sp. lycopersici used in this study could be divided into 2 races according to their pathogenicity to eight differential varieties of tomato. Of 10 isolates tested, 6 were classified as race 1, while 4, as race 2.
