Background and Objectives : Palindromic rheumatism (PR) is known to be triggered without any obviously inciting events in most patients, although, in a few cases, attacks have been noted to relate to another events such as weather change, childbirth, ingestion of certain foods, or over-exercise. The aim of this study was to characterize the triggering factors on palindromic attacks. Materials and Methods : We evaluated sixty-four patients with PR for the presence of triggering factors and the relationship between attacks and triggering factors by interview of patients. We considered that there was an probable association between episodes and PR, if episodes within 24 hours prior to PR had triggered at least 50% of all attacks and a definite association between episodes and PR, if episodes within 24 hours prior to PR had triggered 100% of all attacks. Results : In 15 patients (35.9%), there was a possible association between episodes of PR and initiating events. In 8 patients (12.5%), there was a definite association between episodes of PR and initiating events. The triggering factors were physical over-activity including exercise (19/64: 29.7%), foods, such as rawfish, crab, and chicken, including alcohol (19/96: 19.8%). However, there were no difference between the groups with and without the triggering factor in sex ratio, duration and onset of PR, the positive rate of rheumatoid factor and involved sites. Conclusion : Our observations showed that PR was triggered by physical over-activity more than in previous reports and hypersensitivity to foods was a causative factor in some patients with PR. However, patients with triggering factors had a similiar clinical profile to patients without triggering factors.

최근 컴퓨팅 환경이 변화함에 따라 현재 운용되고 있는 레거시 시스템을 새로운 환경에서도 운용할 수 있도록 시스템을 현대화하는 연구가 활발히 진행되고 있다. 특히 소프트웨어 재사용 기술과 함께 컴포넌트 기술이 개발, 보급됨에 따라 기존 시스템을 컴포넌트로 변환하거나 연계하는 방법들이 연구되고 있다. 그러나, 레거시 시스템은 중요성과 안정성으로 인해서 쉽게 새로운 시스템으로 전환하기가 쉽지가 않다. 그래서, 레거시 시스템의 현대화를 위해서 재개발, 변환, 래핑 등의 다양한 방법을 사용해서 새로운 시스템 환경에서 사용 가능하게 한다. 이 방법을 사용함으로써 신뢰성과 안정성을 향상시킬 수 있게 된다. 본 논문에서 추출정보, 플로우 그래프, 프로그램 콜 그래프, 패러그래프 플로우 그래프 등에서 사용될 핵심변수와 패턴 식별을 위한 레거시 시스템과 릴레이션 방지 기술을 가진 효율적인 코볼 코드 분석기를 소개한다. Computing environment is changing much recently Legacy system should be executed in new environment. Modernization research of system is progressing so that can be executed in these environment. According to the development and supply of the component technology and software reuse technology. We are studied and interested in conversion and connection of component methods. But the importance of legacy system, it is hard to convert by easily new system. Make use of legacy system just as it is using methods of redevelopment, transformation, wrapping etc. It is available in new system environment and improve trustability and stability. In this paper, we introduce a legacy system and design a efficient cobol code analyzer which has a redundant relation preventing technology to create core variable and pattern discernment that is used to abstraction information and flow graph, program call graph, paragraph flowing graph etc.

The effect of alloying elements addition, austenite content and distributions on the tensile properties and corrosion resistance of duplex and super duplex stainless steels has been investigated by changing heat treatment conditions. With the addition of N and Cu, the austenite content of duplex stainless steels increased. After heat treating the super duplex stainless steel, the austenite content increased above 1200℃ and the ferrite single phase temperature shifted to 50℃ high in comparison to duplex stainless steel. Due to the stored energy induced from cold rolling the super duplex stainless steel. the specimen with fibous structure showed to be increased in austenite content compared to the specimen with dispersed structure. Tensile strengths decreased and elongations increased with increasing austenite content. The super duplex stainless steel with fibrous structure showed superior tensile strengths and elongations to the fibrous duplex stainless steel and super duplex stainless steel with dispered structure. The effect of Cu and CU+W addition on tensile properties was small. The passive current density and critical current density of high alloyed super duplex stainless steel showed value in comparison to duplex stainless steel. The Cu+W added super duplex stainless steel appeared the highest corrosion resistance among all specimens.

전기로 슬래그의 재활용을 위해서는 우선적으로 환경적 안정성이 검증되어야 한다. 본 연구에서는 aging 처리한 전기로 슬래그의 환경 안정성을 availability test와 ANC test를 통한 단기평형 용출과 장기용출 거동을 조사하였다. 또한 모델링을 통해 단기평형 용출실험의 결과와 비교할 수 있었다. 실험결과 공기 중 aging을 수행하는 것은 산중화능을 증대시켜 환경적으로 안정성을 높이는 방법이라 판단된다. 또한 장기용출 실험결과 L/S ratio가 작은 경우 전기로 슬래그 자체의 높은 pH에 의해 반응기 내부의 pH가 영향을 받게 되어 용출된 중금속의 양은 매우 미량이였다. ANC test와 availability test의 결과는 MINTEQA2를 이용한 모델링과 비교되었으며, 전기로 슬래그에 대한 용출특성이 모델링을 통하여 예측 가능할 것으로 판단된다. It is important to comfirm environmental stablity of electric are furnace(EAF) slag which has a low recycling ratio due to expansibility and breaking-down-possibility. The objective of this study is to investigate the environmental stability of EAF slag through availablity test, ANC test and long-term leaching test. Modeling data was compared with the result of short-term equilibrium leaching test. The results of ANC test and availability show Processing aging in the air is the way to increase environmental safety by enhancing acid neutralizing capacity. And result of long term leaching experiment shows that increasing L/S ration of almost every heavy metal at the same flow increased amount of leaching. Compared the results from ANC test and availability test to result of copying by MINTEQA2, each deposit curve of objective materials copied by MINTEAQ2 corresponds to the test results, and that is effective to predict leaching properties of EAF slg.

This research aims to find granulation and organic removal of the piggery wastewater with the upflow blanket filter (UBF) reactor. UASB process had the effect of high pH on the granulation phase. But teh effect was decreased after the granule formtion. The filter zone of the UBF reactor had the function of GSS and contributed to removing the organic because of its biofilm formtion. The removal rates of total COD and soluble COD were 70% ~ 80% and 60 ~80% at an influent organic loading range of 2 ~ 17.4 kgCOD/m?.d, respectively. The methane production rate with the organic removal was 0.21 ~ 0.34 ℓCH?/gCOD ? and the maximum methan production rate was 0.34 CH?ℓ/gCOD ? at the volumetric loading 5 kgCOD/m?.d.

Objective: TRAIL(also called Apo-2L) is a member of the tumor necrosis factor(TNF) family of cytokines which induces apoptosis cell death in a variety of tumor cell lines. It mediates its apoptotic effects through one of two receptors, DR4 and DR5, which are members of the TNF receptor family, and whose cytoplasmic regions contain death domains. TNF and Fas ligand induces apoptosis in tumor cells; however, their severe toxicity toward normal tissues hampers their application to cancer therapy. We examed if paclitaxed and/or Apo-2LTRAIL induces apoptosis of cervical cancer HeLa, SiHa, ME-180, and CaSki cells. Mehods : We have demonstrated that paclitaxel and Apo-2L/TRAIL induces apoptosis of cervical cancer HeLa, SiHa, CaSki and ME-180 cell lines in a dose-dependent manner. HeLa, SiHa, ME-180 and CaSki were obtained from American Type Culture Colection. Recombinant Human TRAIL(Chmicon). DR4 and DR5 were purchased from Santa Cruz. Paclitaxel, MTT assay Kit, Acridine orange and Ethium bormide were purchased from Sigma. HeLa and SiHa were grown in DMEM. ME-180 and CaSki were grown in RPMI. Tripan blue stain and MTT assay were done for cytotoxicity. Annexin V-FITC and PI(propidium iodide) flowcytometry for apoptosis assay. DR4 and DR% were expressed by Western Blot. Fluorescent Microscopy used Acridine orange(AO) and Ethium bromide(EB). Results : Importantly, concurrent treatment of cervical cancer cells with paclitaxed and Apo-2L/TRAIL induces significantly more apoptosis than Apo-2L/TRAIL alone. Conclusion : We need further studies which reveals possible therapeutic potential in the women with cervical cancer by suing Apo-2L/TRAIL.
