『Classified Collection of Medical Prescriptions』(『醫方類聚』) is a medical book which classifies and edits the existing books. First of all, it is not until finishing the study of reference books that we can study the 『Classified Collection of Medical Prescriptions』in earnest. We did not take traditinal non-systematic methods to study the reference books of 『Classified Collection of Medical Prescriptions』systematically. We investigated the title of 'refernce book's name' as a reference book and did not investigate re-reference books. The number of reference books are one hundred forty-two volumes. Most of the reference books are medical books; some books are about Taoism and Buddhism. The title of the reference books are given a name by various methods. But these methods have a lot of problems. First, the same title book misapply an alias, the original text name and an abbreviated name. Second, a chapter name misapplies reference books. Third, reference books misapplies a chapter name. Fourth, the writer and book name misapplies reference books and so on. From quotation collection about 『Classified Collection of Medical Prescriptions』's characteristic point follows below in three kinds. First, it emphasizes medical therapy. Second, most of Song(宋) period, Geum-Yuan(金, 元) period of China reference books take place in here. During this period it had accepted studying theory from clinical accumulation and the result of re-clinical studies reception based on theory research, and also had accepted Geum-Yuan's expansive theory. Third, by adding technical books of a professional assortment, it has raised its profession of division.

Modified surgical technique for transposition of the inferior alveolar nerve followed by immediate placement of endosseous implants in mandibles with moderate to severe atrophy are presented. Five transpositions of the inferior alveolar nerve together with the installation of 10 implants were performed in four patients. The mean postoperative follow-up time was 17 months, with a range of 8 to 20 months. All implants with functioning pontics remained stable, with no mobility or symptoms of pain and infection during the follow-up period. Neurosensory evaluation was performed using the two-point discrimination test. Two patients had objective neurosensory dysfunction at postoperative, but all the nerve function were reported as normal by the patients 4 months postoperatively.

Malaria is the world's most important parasitic infection. Although it has been erw5cated from temperate zones including Korea, increasing numbers of travellers visit tropical malarious countries and imported malaria becomes important medical problem in the developed countries. In Korea with increasing travellers to malaria-endemic area, the incidence of imported malaria shows rising tendency same as the developed countries. It becomes important to personal general personal protective measures and chemoprophylaxis to trevellers, when employed in appropriate manner, that can be highly effective in preventing malaria. We recently experienced a case of in Plasmodium vivax malaria with delayed manifestations due to inadequate chemoprophylaxis. A 53-year-old woman with history of trevel to East Africa 4 months ago and chief complaint of fever was diagnosed as tertian malaria. She had irregularly taken prophylatic antimalarial during travel and had not taken it after return but should have taken it at least 4 weeks after return.

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.

This paper presents algorithm and system for biometric person identification utilizing vein pattern. In order to represent hand vein images, we utilized template matching. We implemented the algorithm with DSP(ADSP-21061). This paper presents the detailed algorithm, system and performance evaluation results.
고온·알칼리성 Bacillus sp.의 Catabolite Repression 저항성 변이주로부터 Cellulase 및 Xylanase의 생산

고온·알칼리성 cellulase 및 hemicellulase 생성 미생물을 분리할 목적으로 pH 10.3의 PY-CMC배지에서 55℃로 3회 연속 직접배양하여 효소 생성능이 우수한 20여균주를 분리하였고, 그 중에서 2개균주를 최종 선정하여 균학적 성상을 조사한 결과 고온·알칼리성 Bacillus속과 거의 일치하였다. 선정, 동정된 고온·알칼리성 Bacillus sp. F204와 F1020은 α-1, 4-glucose 등에서는 효소 생합성이 왕성하였으나, glucose와 같은 단당류에서는 효소가 전혀 유도되지 않았는데, 이 두 균주는 carbon catabolote repression을 받고 있었다. 2-deoxy glucose는 야생주에서는 강력한 repressor로 작용하였고, 야생주의 catabolite repression을 해제 시키는데 antimetabolite로 작용한다는 것이 밝혀졌다. NTG(500㎍/㎖, 50℃, 20∼60분)와 UV(2분) 처리후 2-DG(20mM)에 직접배양하여 강력한 catabolite repression resistant strain인 M-211과 M-367을 분리하였다. M-211과 M-367은 2-DG를 energy원으로 이용하였으며, glucose에 대하여 CMCase는 1.5%, avicelase 및 xylanase는 약 1.0%까지 저항성을 보였다. 또한 두개의 변이주의 효소 활성은 CMCase 2배, avicelase 1.5배 및 xylanase3배의 증가를 보였으며, 각 효소생합성을 위한 gene expression은 cAMP-independent transcription을 하는 것으로 나타났다. Cellulase and xylanase synthesis of thermophilic alkalophilic Bacillus sp. F204 and F1020 isolated in our lab, were repressed by glucose and induced by compounds structurally related to α-1,4 linkage (avicel cellulose and xylan et. al.). Catabolite repression-resistant mutants were obtained through treatment of NTG(500㎍./㎖), UV(2 min) and enrichment culture in 2-deoxy glucose (20 mM) containing PY-glucose on the wild type strain. T재 catabolite repression resistant mutants were not repressed by glucose and produced cellulase complex and xylansase when in grown in the presence of 1.0% glucose and 30mM 2-DC, which were repressors in wild type. Enzyme production was greater with the mutants (CMCase of 2 times, avicelase of 1.5 times, xylanase of 3 times) than with the wild type strains under various test conditions. T재 mutants M-211 and M-367 were potential catabolite repression resistant mutants and their gene expression was cAMP independent transcription.

This paper proposes an enhanced algorithm for person identification system utilizing hand vein pattern. The conventional algorithm does not cope with distortion caused by image rotation caused by misplaced hands on the imaging device. A straightforward approach to consider the rotaional compensation required too much computational load, thus, we devised an approach to expect the rotation direction along with image translation, reducing the compuational requirement dramatically. In this paper, we present the detail of the algorithm with experimental results with the new algorithm.
