The aim of study was to investigate genetic diversity for the calpain/calpastatin gene in three Hanwoo breeds [(Brown (n=62), Brindle (n=81) and Jeju Black (n=30)]. Random samples from three breeds of Hanwoo were selected and genotyped for the 7 SNPs of calpain/calpastatin using TaqMan method. Allele frequencies were investigated for CAPN1/CAST gene. Allele frequency of CAST2 SNP was 0.75, 0.59 and 0.22 for Brown, Brindle and Jeju black, respectively. The CAST3 revealed allele frequency of 0.59 and 0.57 in Brown and Jeju Black, while it showed very low allele frequency (0.07) in Brindle. In particular, favorable allele (G allele) for the CAPN1-2 SNP which was shown a strong association with tenderness in Taurine and Indicine cattle revealed 16% and 17% higher allele frequency in Brown Hanwoo (0.82) comparing Brindle (0.66) and Jeju Black Hanwoo (0.65). AMOVA demonstrated that among population variance occupied only 10% of total variance and among individual variance was 0%, while within individual variance was 90% of total variance. This result showed that population effect contributed very small portion of genetic to these three Hanwoo breeds, while within individual variance contributed large portion of genetic diversity within these Hanwoo breeds. In conclusion, three Hanwoo breeds (Brown, Brindle and Jeju black) showed a genetically homogeneous based on the 7 SNPs of CAPN1/CAST gene and it came from same ancestor to form modern Hanwoo breed.

Anthor examined the small water supply works of 108 which had been excuted in Jenbug region before the year of 1977, and this is the report on the evaluation of the works and the proposed rational methods for the works. It was found that the excuted woks had many faults. Though water works were required the highly specialized abilities in engineering and administration, water works were excuted in too small units of each villagage, and the many fauts of the works were resulted. Accordingly, the method of excuting the water supply works with the larger units bound several villages is proposed as the rationl.

A new coating process known as metalliding has been adopted to have the diffusion coating of aluminium on steel from molten fluorides(29.2wt.% LiF-11.7wt.% NaF-59.lwt.% KF, FLINAK). Experiments were carried out in argon gas atmosphere. The electrolytic cell consists of a steel cathode and a consumable aluminium anode. The reagents were vacuum dried to remove the moisture for 24hrs. at 400 C and the electrolyte was pre-electrolyzed to remove residual impurities. The influence of the co-deposition of manganese was also investigated. The quality of deposit was analyzed by SEM, EPMA and also examined by Micro-Vickers hardness, and corrosion tests. Deposit layer was identified as an aluminium-rich iron alloy layer caused by diffusion process. The optimum condition for the metalliding was found to be the bath temperature, 575℃, the amount of AlF_(3), l0wt.%, and the current density, 50 to 150mA/cm^(2). Addition of manganese fluoride (up to 5wt.%) as a co-deposit element improved significantly the quality of deposit layer.

Background: Immediate implant placement has become an acceptable treatment for the edentulous area. The advantages of the immediate implant placement include considerable decrease in time from tooth extraction to placement of the finial prosthesis, fewer surgical procedures, and better acceptance of the overall treatment plans. But the success is dependent on the quantity and quality of the extraction socket. The purpose of this study is to evaluate the success of the immediate implant placement. Materials and Methods: Twenty-one sites in 16 patients were selected for the evaluation of the immediate implant placement. All of the cases were followed using clinical and radiographic examinations. Criteria of success were the absence of peri-implant radiolucency, mobility, and persistent pain or sign of infection. Results: Of the 21 implants, 13 implants have been succeeded. Of the 13 implants, 10 implants were replaced for the periodontal disease and 3 implants were replaced for the trauma. Conclusion: The criteria of the success in immediate implant placement are as follows. 1) Implants placed into fresh extraction sockets have a high rate of survival. 2) Implant should be placed as close as possible to the alveolar crest. 3) Implant placed into available bone beyond the apex have a high success rate.

During a three-year period, 600 patients were admitted to the Asan Medical Center because of biliary tract diseases. Both aerobic and anaerobic cultures were performed in 313 patients with cholangitis (bile : 253, blood : 113, both : 53). Of these patients, 189 were positive(bile 159. blood 68. both 38). The most common organisms were E. coli, K pneumoniae, and P. aeruginosa in both bile(respectively, 49.7%, 20.8%, 51.5%) and blood cultures(respectively, 45.6%, 26.5%, 22.1%). Antibiotic therapy did not sterilize bile, but selectively increased the proportions of P. aeruginosa. There was no significant difference in biliary bacteriology according to the history of biliary surgery, or the presence of percutaneous biliary drainage or underlying disease. More than 95% of gram-negative organisms isolated was highly susceptible to imipenem and amikacin. P. aeruginosa was resistant to ceftazidime in 63.3% which might be associated with overuse of the drug during the study period. Further studies will be necessary in patients with cholangitis to determine whether newer antibiotics replace previous combination therapy.

Human sparganosois was reported more than 100 cases in Korean population. However no case reported yet in Korea as a patient was infected by sparganum from other geographical area, such as Thailand. The case we are reported here is a 38 year-old Korean male who had been suffered from mass being a small, round and soft consistance in upper portion of his right thigh. The patients stated that he had an opportunity to eat living snake in Bangkok, Thailand during trip. As therapy praziquantel (75㎎/㎏/day) was given p.o. for 14 days, but in vain to cure. Following medical treatment, surgical exicision was performed to remove a alive, soft, whitish-milky, mobile and elongated sparganum. Serlogical test by micro-ELISA for sparganum-specific antibody revealed a high serum antibody level of absorbance 0.67 (positive criterion: absorbance 0.22).
