Abstract:
본 발명의 목적은 디자이너가 새로운 이미지를 구상할 때의 창작의 고통을 덜 수 있고, 동시에 자연스러운 이미지를 생성할 수 있는 자동 이미지 생성 방법을 제공하는 것을 목적으로 한다. 이를 위하여 본 발명에서는, 생성할 이미지의 크기, 생성할 이미지의 구성, 생성할 이미지의 색상 중에서 선택된 하나 이상의 초기 조건을 설정하는 초기 설정 단계 최대 체적 분율, 최대 반복 계산 횟수, 수렴 조건, SIMP 방법의 페널티 값, 물성 값, 경계 조건 중에서 선택된 하나 이상의 위상최적화 과정을 위한 변수를 설정하는 전처리 단계 생성할 이미지를 유한개 요소로 나누고, 나누어진 각각의 유한 요소들에 대해 물성 값을 부여하며, 부여된 물성 값에 대한 필터링을 수행하고, OC, MMA, 유전 알고리즘을 포함하는 최적화 기법의 그룹에서 선택된 하나의 최적화 기법을 적용하여 설계 변수를 최적화하고, 최적화 과정에서 얻어진 설계 변수를 새로운 결과 설계 변수로 업데이트 한 후, 업데이트 된 설계 변수가 미리 설정된 수렴 조건을 만족하는지 여� �를 확인하여, 수렴이 안 되었을 경우에는 최적화 과정을 다시 수행하고, 수렴이 되었을 경우에는 결과물을 출력하는 위상최적화 처리 단계 및 위상최적화 과정을 통해 얻은 결과적인 설계 변수 값을 디지털 이미지의 RGB값으로 변환하는 후처리 단계를 포함하는 최적화 기법을 이용한 자연스러운 이미지의 자동 생성 방법을 제공한다.
Abstract:
PURPOSE: A malignant undifferentiated cancer stem cell target peptide is provided to effectively and accurately deliver anti-cancer drug to tumor cells by targeting nestin-positive cells of tumor cells. CONSTITUTION: A malignant undifferentiated cancer stem cell target peptide GICT has AQYLNPS sequence which can selectively recognizes and combines with the malignant undifferentiated tumor stem cells. A marker for diagnosing malignant cancers uses the cancer stem cell target peptide GICT having AQYLNPS sequence. A method for screening the cancer stem cell target peptide, which can selectively recognize and combine with the malignant undifferentiated cancer stem cells, uses phage display technique. The method for sorting and inspecting the cancer stem cell target peptide comprises the following steps: prying the cancer stem cell target peptides through sorting the cancer stem cell bonded phage and analyzing the individual phage combination aspect by using the page display technique; analyzing combining ability of the pried cancer stem cell target peptide with the various cells; sorting and verifying the protein bonded with the pried cancer stem cell target peptide; verifying the cancer tissue transmission ability of the cancer stem cell target peptide in a cancer model mouse; verifying undifferentiated cancer stem cell specific targeting ability of the cancer stem cell target peptide in the brain tumor organization; and confirming the cancer cell growth inhibition ability in the tumor model mouse of the tumor stem cell target peptide.
Abstract:
The present invention relates to tumor stem cell targeting peptide GICT which can selectively recognize and bind malignant undifferentiated brain tumor stem cells, and a diagnosis method of brain tumor using the peptide. The present invention provides a pharmaceutical composition for preventing and treating malignant tumor which contains the tumor stem cell targeting peptide denoted by sequence number 1 as an effective component.
Abstract:
PURPOSE: A mesenchymal stem cell in which endostatin and carboxyl esterase are concurrently over expressed and preventing, treating or recurrence suppression method of glioma by using the same are provided to drastically prevent carcinogenesis and recurrence. CONSTITUTION: In a mesenchymal stem cell, endostatin and carboxyl esterase are concurrently over expressed. A preventing, treating or recurrence suppression method of glioma includes a step of injecting the mesenchymal stem cell to all mammals except for human. A manufacturing method of human amniotic fluid-derived mesenchymal stem cell(AF-MSC) comprises the following steps: establishing positive number of primary cell cultivation in a minimum essential medium in which fetal bovine serum(ES-FBS) having 15% of embryonic stem cell, 2mM L-glutamine and 1% of penicillin streptomycin are contained, and 18% Chang culture medium B and 2% Chang culture medium C are supplemented; collecting cells by trypsinization for selective cultivation of AF-MSC; plating in DMEM low dextrose broth supplemented with 10% of FBS, 1% of penicillin streptomycin, 2mM L-glutamine and 4ng/mL basic fibroblast growth factor (bFGF: R&D); and obtaining morphologic interspecies population of the AF-MSC after second round of the subculture.
