  • Due to human life expectancy of the recent development of medical technology recently, it leads to increase the desire for improving the quality of human life, and grow health concerns and needs. Therefore, in order to prevent the occurrence of disease and to check up a disease quickly, research on the development of a biosensor has been actively processed. One of them, the nano-carbon materials, are very suitable for manufacturing biosensor due to their excellent electrical/mechanical properties. In this review, we introduced the recent studies about preparation methods of carbon electrodes using the carbon nano-materials for biosensors as well as its technological applications.

  • This study was intend to develop the optimal design method of suspension bridge by the reliability analysis based on minimization of life cycle cost(LCC). The reliability analysis was performed considering aleatory uncertainties included in the result of numerical analysis. The optimal design was estimated based on life-cycle cost analysis depending on the result of reliability analysis. As the effect of epistemic uncertainty, the safety index (beta), failure probability (pf) and minimum life cycle cost were random variables. The high-level distributions were generated, from which the critical percentile values were obtained for a conservative bridge design through sensitivity assessment.

  • 식품과 사료에서 곰팡이독소 오염은 세계적으로 중요한 문제이다. 곰팡이독소는 곰팡이의 이차대사산물로서 인축중독증을 야기하며 경제적인 손실을 초래한다. Aflatoxin, ergot alkaloid, fumonisin, ochratoxin, tremorgenic toxin, trichothecene 및 zearalenone 등이 식품과 사료에서 흘러 발생하는 곰팡이독소이다. 어떤 곰팡이는 하나 이상의 곰팡이독소를 생산하고, 또 어떤 곰팡이독소는 여러 종의 곰팡이에서 생성되기 때문에 여러 곰팡이독소가 함께 발견된다. 곰팡이독소의 발생에 영향을 끼치는 요인으로는 인위적으로 조절할 수 있는 보관과 환경적 조건도 포함된다. 기후와 같은 비본질적인 요인, 진균류의 계통 특이성 및 계통 변이와 같은 본질적인 요인 및 독소발생의 불안정성은 조절하기 어렵다. 곰팡이독소는 한 종의 동물에 있어서의 감수성과 종에 의존하며 인간에게 갖가지의 만성적 또는 급성적인 영향을 미친다. 그러나 반추동물은 곰팡이독소에 저항력을 가지고 있으며, 이는 반추동물의 위에 존재하는 미생물들이 곰팡이독소의 활성을 억제할 수 있기 때문이다. 곰팡이독소 피해의 경제적인 파급효과는 인축의 수명 단축, 축산물 생산감소, 오염된 식량과 사료의 처리 및 곰팡이독소의 문제점 해결을 위한 연구비용 등을 포함한다. 곰팡이독소 피해감소를 위한 국제적인 노력이 계속 진행되고 있지만 최근에 World Trade Organization이 발효되면서 동 식물이 지역간 자유로운 이동으로 곰팡이독소 피해 경감대책뿐만 아니라 피해측정이 어려워지고 있다.

  • 생체재료란 손상된 생체조직의 기능을 가능한 한 정상에 가까운 상태로 회복시킬 때 이용되는 재료이다. 생체재료는 보건 의료 분야 중 치료, 재활 및 예방의 수단으로 생체에 적용되기 때문에 인간 수명연장 및 사고, 질병의 증가 등에 따라 그 중요성이 점점 증가되고 있는 추세이다. 그럼에도 불구하고, 생체재료 이식에 따른 면역기전에 대해서는 명확하게 밝혀지지 않고 있다. 따라서 본 연구에서는 미생물의 특이 구조를 인식하여 염증반응을 유도하는 TLR (Toll like receptor)을 통한 면역학적 기전을 생체재료 이식시 나타나는 면역반응에 적용하고자 macrophage cell line인 RAW264.7을 이용하여 확인하였다. 생체재료(칼슘-인산계 뼈이식제, PCL microphere)의 특성은 electron microscope(SEM, TEM)을 통하여 관찰하였고 RAW264.7에 의한 세포 독성실험 (MTT와 LDH assay) 결과 세포독성은 없는 것으로 확인되었다. 생체재료가 TLR pathway에 미치는 영향을 Western blotting과 RT-PCR을 이용하여 확인하였으며, 면역반응 시 유도되는 cytokine을 RT-PCR과 ELISA를 이용하여 확인하였다.

  • Space Environment including Solar activities such as Solar explosion, Corona Mass Ejection(CMS) is always not friendly for human. Especially it may be fatal to artificial satellites. The lifetime of geostationary communication satellites are reducing due to plasma such as electrons, protons etc. emitting from Sun. This is because the active components constituting communication satellite are easily affected by plasma. Even though the radiation shielding on the components can be a way to prevent, the cost will be high. So the appropriate shielding is necessary and the study on space environment is also. In this study spacecraft anomalies will be investigated from low earth orbit to deep space spacecraft and the correlation between spacecraft anomalies and space environment events including space explosion, geomagnetic storms etc is analyzed.

  • Sensor network for the human approach in a difficult area and a wide range of surveillance and the boundaries for the purpose and mission is the utilization significantly. In this paper we searched important nodes from the surveillance reconnaissance sensor network based on the virtual data. we generated data within the sensor's measurement range in the data transmitted from sensor nodes, and used PCA(Principle Component Analysis) for searching key node. If the important sensor node searched, and we can have easy management and establishing security measures when security problems is happened about nodes. This is for the sensor network in terms of effectiveness and cost-effectively and is directly connected with life span.

  • 1. Objects of Research Dong-mu Lee Je-ma was tried to solve the diseases of human beings through Sasang Constitutional Medicine with new viewpoints on human beings and life compared with the existed medicine. So it was very important to understand his medical views in order to apply Sasang Constitutional Medicine in clinical treatment. In this paper, I tried to find his medical views on human beings, life, and diseases to get informations in clinical application. 2. Methods of Research It was researched as bibliologically with his writings such as "Dongyi Soose Bowon(東醫壽世保元)", "Dongyi Soose Bowon Sasang Chobongyun(東醫壽世保元四象草本卷)", "Dongmu Yugo(東武遺稿)", "Gyuk-chigo(格致藁)". 3. Results and Conclusions The conclusions were as follows. 1. "I Ching"'s recognition of Things is that based on Yin-yang theory, originated from Taoism, and aimed to 'the Fine point of Easiness and Simpleness(易簡之妙)'. On the other hand, Dong-mu's is that based on Sasang theory, originated from Confucianism and designed to developed 'the Fine point of Easiness and Simpleness' in view of Sasang(四象). 2. Dong-mu Lee Je-ma had devoted himself in his whole life to establishing new paradigm in the Confucianism, inventing new medicine and, furthermore, embodying the spirit of General health maintenance. 3. Dong-mu Lee Je-ma recognized 'the Fine point of Easiness and Simpleness' in view of Sasang and offered new viewpoint of human being through summarizing various existing viewpoints. 4. Dong-mu Lee Je-ma established new viewpoint of life span of human being through offering new ideas such as 'Inherent vitality(命脈實數)', 'Essential power of organ(臟의 本常之氣)' and 'Regimen in ordinary life(生息允補之道)'. 5. Dong-mu Lee Je-ma embodied 'the Fine point of Easiness and Simpleness' in medicine through offering, in a wide meaning, the spirit of the General health maintenance and the spirit of the Positive medical treatment.
