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.

국내 신발산업(Foodwear Industry)은 주로 외국의 대형 바이어에 의존적인 형태로 생산하는 주문자 상표 부착 생산방식이 대부분을 차지하며, 신발 제조에서 인건비가 차지하는 비중이 절대적이어서 대형 바이어들이 중국, 베트남, 인도네시아 등의 저임금 국가로 신발 생산기지를 옮겨가고 있다. 이로 인해 국내 신발산업은 많은 어려움을 겪고 있는 것이 사실이다. 또한 국내의 신발제조기업들도 상당수 해외에 생산공장을 운영하고 있으며, 국내 생산공장은 그 규모가 굉장히 축소되어 있거나 혹은 연구개발 및 부품 조달기지로서의 역할을 수행하고 있다. 이러한 신발산업의 환경에 변화에 대해 산업 차원에서 대응할 필요성이 있다. 앞으로 국내 신발산업이 성장하기 위해서는 전체 공급망의 협업체제를 갖추는 것이 필요하다. 이를 위해서는 신발산업의 공급망 네트워크 구조를 분석하여 비효율적인 부분을 개선해야 하며, 기업간의 비즈니스 프로세스를 새롭게 정립하여 혁신해야 한다. 이에 본 연구에서는 신발산업의 공급망 네트워크 구조를 분석하여 개선 모델을 제시하였으며, 공급망에서 대부분을 차지하는 신발 완제품 제조기업과 부품 제조기업간의 비즈니스 프로세스를 분석하여 개선된 비즈니스 프로세스를 제시하였다.

The purpose of this thesis is to investigate how agalmatolite-product domestic industry has grown in Ockyeon village. Through this case study, it is hoped that we can shed some light on the origin and formation process of Korean traditional handicraft industry. The primary data for the present study were collected by utilizing interview schedule. In addition, informal interviews were held to all producers. The study results can be summarized as the followings : 1) The agalmatolite-product industry in this area was originated from a village which is located 10km away from Ockyeon village, in 1930s. But one of the producers migrated to Ockyeon village in 1959. After this happened, the village had become a new center of the industry. The major reason for this relocation- diffusion was that it was much easier to acquire the material, i.e., agalmatolite, in Ockyeon village than in the original village. It is noted that the industry is material-oriented one in its nature. 2) The development of the industry can be marked by two phases : the first phase covers 1959 ~ 1969 time period, and the second phase falls into 1970 ~ 1985 time period. The first phase refers to the period when the products were made through handicraft. The second phase characterized by the use of machines in its production. During this phase, the products became more diverse, and production level increased. 3) The industry is not specialized in terms of production and merchandizing. With respect to specialization, it is also noted that about half of the producers have additional jobs.

In this study, a vehicle vector using cryptic plasmids was constructed for gene transfer in Helicobacter pylori. pHP51(3.9 kb) and pHP489(1.2 kb) were selected for constructing vectors from cryptic plasmid of H. pylori isolates in Korea. The HindⅢ-digestedDNA fragment(1.2kb) of pHP489 and 1.6kb DNA fragment of pHP51 were ligated with a kanamycin resistance gene(aph3'-Ⅲ) from C. jejuni to produce the recombinant plasmids pHP489K and pHP51K, respectively. Transformation frequency of pHP51K by electroporation was low. But pHP489K could be effectively transformed into various H. pylori strains. In order to design an intermdiate vehicle vector for gene transfer into H. pylori, pBlueHP489K was prepared by recloning pHP489K DNA into pBluescript and pTZ19R vector. This vector permitted the DNA fragment containing pHP489 sequence, aph3'-Ⅲ, and cloned DNA to be cut and self-ligated in the SacⅠ site after cloning. ureA and ureB gene were inserted into pBlueHP489K, resulting in pBlueHP489K/AB. The DNA fragment containing pHP489, kanamycin resistance gene(aph3'-Ⅲ), and urease structural gene was cut away from pBlueHP489K/AB and self-ligated to generate pBlueHP489K/AB. pBlueHP489K/AB made urease-negative H. pylori strains restore their urease activity. By this experiment, pBlueHP489K was confirmed to be the vehicle system for transferring H. pylori genes.

The author present a modified multi-loop algorithm including feedforward for controlling a 55kW step down chopper in the power supply of Maglev. The control law for the duty cycle consists of three terms. The first is the feedforward term which compensates for variations in the input voltage. The second term consists of the difference between the slowly moving inductor current and output current. The third term consists of proportional and integral terms involving the perturbation in the output voltage. This perturvation is derived by subtracting the desired output voltage from the actual output voltage. The proportional and integral action stabilizes the system and minimizes output voltage error. In order to verify the validity of the proposed multi-loop controller, simulation study was tried using Matlab simulink.

Water soluble anti-static coating composition(AS-2001), multi-functional(anti-static and slip-stop)and anti-static functional paint coating agents were formulated. Firstly, the multi-functional coating agents were formulated with AS-2001 and slip stop(SㆍS) with water-born polyurethane. The additive of multi-functional coating agent varied from 5 to 12 wt%, depending on the amount of polyurethane used. The optimum amount of coating agent was 10 wt%, The ratio of coating composition AS-2001: SㆍS was 8:2. The surface resistance and friction factor of coated layer were 10^(9)Ω/㎠ and 0.88 in optimum condition, respectively. Secondly, the anti-static functional paint was formulated with AS-2001 and water soluble paint. The additive amounts of AS-2001 are varied from 5 to 20 wt% depending on the amount of water soluble paint. Results showed that the surface resistance of coated gypsum board decreased up to 10^(6)Ω/㎠ as the amount of coating agent increased. However, water soluble paint was aggregated in 20wt% addition of AS-2001, causing coating problems. Anti-static and anti-stain effects were excellent even though 5 wt% of AS-2001 was added in the board.
