Let denote the orthosymplectic Lie superalgebra spo (2m,1). For each irreducible -module, we describe its character in terms of tableaux. Using this result, we decompose kV, the k-fold tensor product of the natural representation V of , into its irreducible -submodules, and prove that the Brauer algebra Bk(1-2m) is isomorphic to the centralizer algebra of spo(2m, 1) on kV for m .

In this paper, we introduce the automatic speaker identification system 'SPO(Supreme Prosecutors Office) Verifier'. SPO Verifier is a GMM(Gaussian mixture model)-UBM(universal background model) based automatic speaker recognition system and has been developed using Korean speakers' utterances. This system uses a channel compensation algorithm to compensate recording device characteristics. The system can give the users the ability to manage reference models with utterances from various environments to get more accurate recognition results. To evaluate the performance of SPO Verifier on Korean speakers, we compared this system with one of the most widely used commercial systems in the forensic field. The results showed that SPO Verifier shows lower EER(equal error rate) than that of the commercial system.

본 논문에서는 심전도(ECG)와 SPO2를 이용하여 혈류속도를 측정하였다. 심전도(ECG)와 손가락 검지손가락 끝의 SPO2농도로 얻는 맥파를 동시에 측정하여 두 파형의 피크값의 시간차를 분석하여 혈류속도를 계산하는 방법을 연구하였다. 심전도(ECG)와 SPO2를 동시 측정 분석하는 시스템으로서 정상인 10명과 임상참가자 3명에 대한 심전도(ECG)와 손가락 검지 손가락 끝의 SPO2농도로 얻는 맥파를 동시에 측정하여 비교 분석한 결과 자료에서 보는 것과 같이, 심혈관계 환자들이 일반적으로 혈류 속도가 빠르다는 것일 볼 수 있다. 또한 정상인들 중에서도 남자와 여자의 속도차이가 있음을 알 수 있다.

Let $O_n$ and $PO_n$ denote the order-preserving transformation and the partial order-preserving transformation semigroups on the set $X_n=\{1,{\ldots},n\}$, respectively. Then the strictly partial order-preserving transformation semigroup $SPO_n$ on the set $X_n$, under its natural order, is defined by $SPO_n=PO_n{\setminus}O_n$. In this paper we find necessary and sufficient conditions for any subset of SPO(n, r) to be a (minimal) generating set of SPO(n, r) for $2{\leq}r{\leq}n-1$.

The application of LFH-PCR(long flanking homology region-PCR) for Bacillus subtilis gene disruption is presented. Without plasmid- or phage-vector construction, only by PCR, based on a DNA sequence retrieved from B. subtilis genome data base, kanamycin resistance gene was inserted into two genes of B. subtilis involved in sporulation, spoIIIE and spoIIIG. The effect of gene disruption on subtilisin expression was examined and the sporulation frequency of two mutants was compared to that of the host strain. For this purpose, only 2 or 3 rounds of PCR were required with 4 primers. We first demonstrated the possibility of LFH-PCR for rapid gene disruption to characterize an unknown functional gene of B. subtilis or other prokaryote in the genomic era.

MAK18 gene of Saccharomyces cerevisiae, needed for M1 replication, was mapped within 2cM of PET3 on chromosome VIII. From 38kb clone pRE66 carrying SPO11 and PET3, we have localized MAK18 gene whose insert is 2.8kb. MAK18 gene is Iocalized on about 9kb distance from PET3 and about 18kb distance from SPO11 on chromosome VIII.

본 논문에서는 반려동물용 산소포화도 측정 웨어러블 장치를 설계하고 구현하였다. 기존 장치들은 움직이는 반려동물들의 SPO₂를 측정하는데에는 방법이 어렵거나 측정 오류가 발생하여 불편한 점이 있었다. 본 논문에서는 이러한 점을 개선하고 수의학적으로 측정 부위에 대한 새로운 위치를 찾아 가능한 형태의 웨어러블을 설계·구현하고 그 성능을 보였다.

Objective : To present the incidence and management of dural tears and cerebrospinal fluid leakage during corrective osteotomy [Pedicle Subtraction Osteotomy (PSO) or Smith-Petersen Osteotomy (SPO)] for ankylosing spondylitis with kyphotic deformity. Methods : A retrospective study was performed for ankylosing spondylitis patients with fixed sagittal imbalance, who had undergone corrective osteotomy (PSO or SPO) at lumbar level. 87 patients were included in this study. 55 patients underwent PSO, 32 patients underwent SPO. The mean age of the patients at the time of surgery was 41.7 years (21-70 years). Of the 87 patients, 15 patients had intraoperative dural tears. Results : The overall incidence of dural tears was 17.2%. The incidence of dural tears during PSO was 20.0%, SPO was 12.5%. There was significant difference in the incidence of dural tears based on surgical procedures ( PSO vs. SPO) (p<0.05). The dural tears ranged in size from 12 to $221mm^2$. A nine of 15 patients had the relatively small dural tears, underwent direct repair via watertight closure. The remaining 6 patients had the large dural tears, consequently direct repair was impossible. The large dural tears were repaired with an on-lay graft of muscle, fascia or fat harvested from the adjacent operation site. All patients had a successful repair with no patient requiring reoperation for the cerebrospinal fluid leak. Conclusion : The overall incidence of dural tears during PSO or SPO for ankylosing spondylitis with kyphotic deformity was 17.2%. The risk factor of dural tears was complexity of surgery. All dural tears were repaired primarily using direct suture, muscle, fascia or fat graft.

The cell cultures and crude extracts of Bacillus sphaericus 1593 K-5 and its mutant Spo-Dl216 were respectively bioassayed against Culex pipiens var. pollens mosquito larvae. The B. sphaeriucs 1593 K-5 showed toxic activity against the larvae. LC$_{50}$ values (cells/$m\ell$) was 2.6$\times$10$^2$. Also the LC$_{50}$ ($\mu\textrm{g}$ Protein/$m\ell$) of the crude extract was 10.26. However, B. sphaericus Spo-Dl216 didn't show toxic activity against the larvae. The soluble cytoplasmic toxin in broken B. sphaeriucs 1593k-5 cells was partially purified by gel permeation chromatography and ion exchange chromatography. Among the fractions of the gel permeation chromatography only a single fraction was found to be toxic. LC$_{50}$ values ($\mu\textrm{g}$ protein/$m\ell$) of the active fraction was 0.182. The active fraction of the gel permeation was subjected to ion exchange chromatography. Only a single fraction showed toxic activity and its LC$_{50}$ values ($\mu\textrm{g}$ protein/$m\ell$) was 0.02..02.

For the development of a sporeless strain of P. ostreatus we used sporeless strain ASI 2069. We have recovered both nuclear types of strain ASI 2069 as monokaryons of nh9, nh15, nh26 and nh36 (here after referred to as neohaplonts) by protoplasting the mycelium. Crosses between neohaplonts and SSI's(single spore isolates) obtained from a sporulating commercial strain ASI 2180. Five excellent strains are selected from 30 bred strains by quality of fruitbodies and spore number. To development of molecular markers linked to sporeless strain of P. ostreatus, we are screened helicase, recombinase(DMC1) and topoisomerase(Spo11) genes related meiosis by PCR and sequencing. Among three genes, Spo11 gene was identified into molecular marker of sporeless from neohaplonts and bred strains of P. ostreatus.
