  • Tumor immune evasion is a complex process that involves various mechanisms, such as antigen recognition restriction, immune system suppression, and T cell exhaustion. The tumor microenvironment contains various immune cells involved in immune evasion. Recent studies have demonstrated that granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) induce immune evasion in lung cancer by modulating neutrophils and myeloid-derived suppressor cells. Here we describe the origin and function of G-CSF and GM-CSF, particularly their role in immune evasion in lung cancer. In addition, their effects on programmed death-ligand 1 expression and clinical implications are discussed.

  • A transfer loading system for 21' RF band assembly box was developed in the present study. The weight of a box is approximately 60kgf End total weight of one day job per person is about $4,000kg_f$. For an efficient design and manufacturing process, three dimensional design and engineering technique were applied to the presented system. Motion analysis for a popup unit and structural analysis for belt part subjected to the load of box weight were performed, respectively. It was found that the evasion of duty and labor intensity is reduced after appling the developed system to manufacturing field of small and midium business.

  • Planarians show negative phototaxis and have extensive regenerative ability, including the ability to regenerate the brain. Recently the process of regeneration of the planarian brain has been divided into three steps based on the expression of neural markers. In this study, we have analyzed the process of recovery of the light response during head regeneration. Although morphological observations indicated that regeneration of the eyes and optic nerves appeared to be completed by the fourth day, the recovery of the evasion behavior against light was not recovered within 4 days after amputation. Functional recovery of the evasion behavior could be detected starting 5 days after amputation and then gradually recovered. We previously identified genes which are specifically expressed in the brain after the recovery of morphological structures. This characteristic suggested that these genes may be involved in functional recovery of the brain. To investigate the function of these genes, we performed gene knockout analysis using the RNA interference method. The results clearly indicated that these genes are involved in the functional recovery of the visual system.

  • 합성 환경/실험 체계 전술객체 표현 기술 연구는 전술객체들의 위치를 실시간으로 탐지·추적하고 이를 가상현실 내에서 모의하기 위한 기반 기술을 확보하는 것을 목적으로 한다. 이를 위한 기술로써 전술객체 위치 추적 및 모의 기술, 모델 간 공유기술에 대한 연구가 필요하다. 본 논문에서는 우선 센서 데이터 융합과 좌표계 통일을 위한 알고리즘을 연구하였고, 추적자의 유도 방식인 PNG(Proportional Navigation Guidance)를 적용한 추적 기술, 공학급 및 상급 모델의 회피 알고리즘을 적용한 회피 기술을 연구하였다. 또한, 잠수함과 어뢰의 추적 회피 시뮬레이션을 통해 전술객체의 위치 모의를 연구하였다.

  • As a part of environmental pollution prevention and resources recycling, the regeneration of waste tire has been largely contributed to national industry. But, the worker has been evaded this regeneration process by reason of the best mischievous process condition among 3D industries. So, the first, the process condition of regenerating waste tire was analyzed. The second, the equipment or system was developed for the improvement of working strength and environment. The last, researchers intend to solve these problems

  • A multi axis whetstone polishing system, which uses the flow system of the stone polishing machine head, has been developed. The test results show that the defect by line contact polishing does not occur in both ends of the stone and that it came to trim smoothly. In terms of the surface roughness, the corresponding index was decreased by 3.6 times, improving the polishing effect greatly. It decreased significantly the dust and noise with the wet polishing. The factors of the duty evasion at production site can thus be solved with the work environment improvement against the polishing process of the stone industry and work intensive reduction.
