웹의 등장은 인터넷 인구의 엄청난 성장을 가져왔다. 이와 더불어 최근에는 가상 금융 및 저자 상거래 시장 등을 지원하는 웹 상의 데이타베이스 관련 상품들이 속속 등장하고 있다. 이에 기존의 데이타베이스 시스템과 클라이언트-서버 방식으로 동작하던 응용 프로그램들을 웹 환경에 적합한 상호 연동 방식을 요구한다. 본 논문에서는 관계형 DBMS인 SRP를 웹 상에서 동작시키기 위한 통로인 SWeS를 제시한다. SWeS는 CGI를 이용한 응용서버 방식으로 구현되었으며, 동적 서버 교체와 페이지 단위의 결과 전송 기법 등을 사용해 가용성 및 동시성, 확장성을 높이는 구조를 갖는다. As the World Wide Web's popularity grows very rapidly, database applications that support internet commerce like virtual banking and electronic commerce come out with a rush. So database applications operating on the client-server architecture require new architecture which can support efficient operations on the Web environment. In this paper we present SWeS, the relational database gateway which connects SRP RDBMS to Web. SWeS has CGI application-server architecture. SWeS provides efficient structure by using both dynamic server replacement scheme and page level transmission of results to achieve availability, concurrency, and scalability.

Objectives: This purpose of this study was to analyzed the Biological Activities of CA Yakchim Fluid. Methods: The protein content, glucose content, crude fat content, crude ash content in CA Yachim fluid were analyzed, and DPPH radical scavenging, inhibition of COX-2 activities were investigated. Also TNF-α, IL-6, GAPDH as inflammatory cytokines were measured. Results: The protein, 1.46%, glucose, 0.13%, crude fat 96.18%, crude ash 0.51% in CA Yachim fluid were confirmed. The electron donation ability of CA Yakchim on DPPH WAS 21%. The inhibition of COX-2 activity of CA Yakchim fluid was 68%. The TNF-α, IL-6 were increased in RAW 264.7 treated with LPS, and were decreased in RAW 264.7 pre-treated with CA Yakchim fluid. Conclusions: We conclude that the CA Yakchim fluid has anti-oxidant, anti-inflammatory activities and inhibition effect of the inflammatory cytokines.

Objectives: The aim of this experimental study was to investigate the component of HO Yakchim and prove its anti-oxidant and anti-inflammatory effect. Methods: Content of protein, glucose, crude fat and crude ash was calculated. Anti-oxidant effect was measured using DPPH free radical scavenging activity. Anti-inflammatory effect was measured with COX-2 kit and RAW 264.7 macrophage. the concentration of TNF-α and IL-6 was measured by Enzyme-linked immuno-sorbent assay. Results: HO Yakchim is consist of 0.09% of protein, 0.23% of glucose, 97.04% of crude fat and 0.37% of crude ash. HO Yakchim showed better anti-oxidant effect than its BHA control sample. The COX-2 inhibiting capacity of HO Yakchim was better than its Indomethacin control sample. Inflammatory cytokine production was reduced but not at transcription level. Conclusions: These results represents that HO Yakchim is composed of protein, glucose, crude fat and crude ash. HO Yakchim anti-oxidant and anti-inflammatory effect.

Objectives: CS has been used as effective pain reducing pharmacoacupunture in clinical fields, however its constituents and physiological activity have not been yet certified by experiment. This experimental research was to analyze the component of CS Yakchim and prove its anti-oxidant and anti-inflammatory effect. Methods: Content of protein, glucose, crude fat and crude ash was calculated. Anti-oxidant effect was measured using 1,1-diphenyl-2-picryl hydrazyl(DPPH) free radical scavenging activity. Anti-inflammatory effect was measured with COX-2 kit and RAW 264.7 macrophage. the concentration of TNF-α and IL-6 was measured by Enzyme-linked immuno-sorbent assay. Results: CS Yakchim is consist of 0.17% of protein, 0.32% of glucose, 95.19% of crude fat and 0.32% of crude ash. CS showed better anti-oxidant effect than its control sample. CS COX-2 inhibiting capacity was better than its Indomethacin control sample. Inflammatory cytokine production was reduced but not at transcription level. Conclusions: These results showed that CS Yakchim is consist protein, glucose, crude fat and crude ash. CS Yakchim anti-oxidant and anti-inflammatory effect.
