제어 비트를 통한 직류 성분 제거 방법으로 주로 코드워드 끝단에서의 WRDS(word-end running digital sum) 기준을 적용하고 있다. WRDS 기준에 의한 직류 성분 제거 방법은 계산 및 구현이 쉬운 반면에 제어 비트 및 코드워드의 길이가 길어질수록 성능이 저하되는 단점이 있다. 복잡도가 높은 대신 최적의 성능을 갖는 방법으로 MSW(mean-square weight) 기준이 있다. 본 논문에서는 MPRDS(minimum peak RDS)라는 고밀도 광 기록 저장 장치를 위한 변조 코드의 새로운 직류 성분 제거 방법을 제안하였다. 이 방법은 계산 및 구현상의 복잡도가 MSW 기준에 비해 현저하게 낮으면서도 제어 비트 및 코드워드의 길이가 증가하더라도 MSW 기준에 의한 성능에 근접함을 입증하였다.

This research was carried out to investigate the optimal conditions ssociated with the RIA procedures such as a bridging phenomena, prozone effects and a new separation methods etc. The results obtained were summarized as follows: 1. The lgG fractions of donkey anti-rabbit IgG sera were purified by Protein-A-Sepharose affinity column, which indicates that Protein-A an affinity for IgG class of donkey antiserum. 2. In coating the IgG fraction on polystryene tubes, incubation conditions made no differences between 2 hr at room temperature and overnight at 4$^{\circ}C$. 3. There were no significant differences between 1st antibody-coated tube and 2nd antibody-coated tube as a separation method when compared in terms of reproducbility. A better reproducibility may be expected if the titers of 1st antibody for the progesterone to be assayed and of corresponding 2nd antibody are reasonably high. 4. The titers of anti-progesterone antibody for 3H-progesterone and progesterone-11HS-125I were 1:300 and 1:700 in liquid-phase, and 1:100 and 1:300 in solid-phse for the separation methods. 5. A bridging phenomena in which a standard curve is long and shallow were observed when progesterone-11HS-125I was used for the tracer, but not in 3H-progesterone. 6. A prozone effect in a solid-phase system, especially 1st antibody-coated tube method was observed which the degree of inhibition was significantly different although zero bindings look the same. In this case, the titration curve should be made both in the absence and in the presence of a, pp.opriate amount of competiter, standard, respectively.

This study is intended to understand an implication and significant of anti-design and Italian radical fashion. Anti-design and radicalism is the main stream or origin and essence of post-modernism which hs been swaying our society at large through modern culture, economy, art, fashion etc, from the latter part of 1960s. In this paper, the author classified the italian radical fashion with the Archizoom, the Alchymia, the memphis fashion. In post-modernism fashion, radical fashion design of the Archizoom, Alchymia and Memphis group is in part a menifesto and in part a noncanonical history of the most progressive and heretical experiments of the world of fashion. Anti-designers of Italy call for a theory an practive in which the old methods and instruments and the old commendments of modernism are banished. They looked on fashion as material culture, a creative field with its own independent foundation and endowed with its own strong artistic intuition. IF radical design is dead, the energy it has stirred up is still alive nd kicking. One of the most progressive and well-informed culture milieus in Milian, seved as a point of reference for the vanguard of fashion.

Purpose - The purpose of this paper was to analyze the Chinese government's announcement of the RMB's appreciation on July 1, 2010, and its aim was to ascertain whether the appreciation has affected Chinese export prices by empirically measuring the degree of the exchange rate pass-tough on those prices. Research design, data, and methodology - Using 73 HS trade categories with cross-industry and time-series data, the panel estimation of a fixed-effects model has been applied to measure the degree and stability of any exchange rate pass-through effects. The estimation results show that the export prices of most trade categories were affected by the exchange rate changes. The pass-through effect was generally small, at about -0.485, and statistically significant in most export prices. Results - The empirical results indicate that China would lose its advantage and competitiveness in export if the RMB were appreciated continuously and rapidly because its export goods would no longer operate under strong monopolistic competition. Conclusions - The implications for China's exchange rate policy suggest that it would be better for the RMB to appreciate slowly and gradually rather than radically. It is clear that it would be allow the capital free flow in Chinese overall economic interest to reduce the continuous appreciation pressure on the currency and pave the way for improvements in export distribution competitiveness.

Origin regulation of Korea AESAN FTA prescribe by general standard fulfills alteration standards 40% standard or HS 4 units three times regional deputy inflicts, and define in item different place of origin(PSR) about 447 items as the exception. Also, Korea AESAN FTA except broad principles that decide place of origin in ASEAN FTA accumulation standard, smile standard, place of origin disapproval process standard and directly various repletion standard such as transport principle introduce. But, most export trader are circumstance judging can charge preferential tariff if export trader submits sending certificate of origin in the customs service without deep comprehension about place of origin regulation. Therefore, will have to be knowing well place of origin decision standard and creation trick of certificate of origin to receive exactly preferential tariff benefit. Also, because it can be difficult that all registered customs brokers who is acting for certificate of origin issuance booking get acquainted in place of origin problem, it is expected to can become confrontation plan train FTA and place of origin professional registered customs brokers.

When glycosaminoglycan (GAG)-degrating enzymes were measured in normal human stool suspensions, all 5 tested different stools degraded titrable heparin and acharan sulfate. GAG-degrading bacteria were screened from the isolates of human stools. Among them, HJ-15 had the most potent activities of heparinases (GAGs-degrading enzymes). However, HJ-15 produced the enzyme even if in the media without heparin. Acharan sulfate lyase was induced by acharan sulfate and heparin. Heparinase production was also induced by these GAGs. These enzymes, acharan sulfate lyase and heparinase, were produced in exponential and stationary phase of HJ-15 growth, respectively. Optimal pHs of the acharan sulfate lyase and heparinase activities were 7.2 and 7.5 respectively. the biochemical properties of HJ-15 was similar to those of B. stercoris. However, difference from B. stercoris was utilization of raffinose. this HJ-15 also degraded chondroitin sulfates A and C.

Brittle fracture of structures excited by earthquakes can be prevented by adding a tuned mass damper (TMD). This TMD must be optimum and suitable to the physical conditions of the structure. Compressive strength of concrete is an important factor for brittle fracture. The application of a TMD to structures with low compressive strength of concrete may not be possible if the weight of the TMD is too much. A heavy TMD is dangerous for these structures because of insufficient axial force capacity of structure. For the preventing brittle fracture, the damping ratio of the TMD must be sufficient to reduce maximum shear forces below the values proposed in design regulations. Using the formulas for frequency and damping ratio related to a preselected mass, this objective can be only achieved by increasing the mass of the TMD. By using a metaheuristic method, the optimum parameters can be searched in a specific limit. In this study, Harmony Search (HS) is employed to find optimum TMD parameters for preventing brittle fracture by reducing shear force in additional to other time and frequency responses. The proposed method is feasible for the retrofit of weak structures with insufficient compressive strength of concrete.

Polyamines such as putrescine are small, ubiquitous polycationic molecules that are required for optimal growth of eukaryotic and prokaryotic cells. These molecules have diverse effects on cell physiology and their intracellular content is regulated by de novo synthesis and uptake from the environment. The studies presented here examined the structure of a putative polyamine transporter (Pot) operon in Streptococcus pneumoniae (pneumococcus) and growth of pneumococci in medium containing putrescine substituted for choline. RT-PCR experiments demonstrated that the four genes encoding the Pot system are co-transcribed with murB, a gene involved in an intermediary step of peptidoglycan synthesis. Pneumococci grown in chemically-defined media (CDM) containing putrescine without choline enter logarithmic phase growth after 36-48 hs. However, culture density at stationary phase eventually reaches that of choline-containing medium. Cells grown in CDM-putrescine formed abnormally elongated chains in which the daughter cells failed to separate and the choline-binding protein PspA was no longer cell-associated. Experiments with CDM containing radiolabeled putrescine demonstrated that pneumococci concentrate this polyamine in cell walls. These data suggest that pneumococci can replicate without choline if putrescine is available and this polyamine may substitute for aminoalcohols in the cell wall teichoic acids.
