Acquired Immune Deficiency Syndrome is the state which develops after complications with the infection from HIV. Irrespective of their state, all HIV infections have infectivity. According to a 2013 U.N. AIDS global report, the number of reported newly infected with HIV is constantly falling, while that of Korea has been increasing over recent years and it surpassed 10,000 in 2013. This phenomenon might be attributed to the unusualness of the blood test for early detection of HIV infection. From this fact, we can assume that we have strong possibilities for encounters with infections in the office. But many misconceptions about the disease makes patients try to hide their medical history, which can lead to a nationwide spread of the infection without proper management. Even though it may be difficult to take care of HIV patients in smaller dental offices, large scale hospitals have the means to arrange protocols to treat them. We present a case about dental treatment of a patient with AIDS that has a history of cerebral infarction and hepatitis type B under general anesthesia. The purpose of this case report was to discuss the special considerations of dental care for patients with HIV.
Through the theoretical study on Sa-sang constitutional medicine from a evolutionary point of view, the result was obtained as follows. 1. The system of Sa-Sim-Sin-Mul(事心身物) in Sa-sang constitutional medicine is similar to the theory of evolution of Teilhard de Chardin. 2. The concept of Yin and Yang in Sa-sang constitutional medicine can be set up by the demand and necessity in the progress of evolution and the time of the differentiation of functions. 3. The Sung-Jung(性情) of each Sa-sang constitution can be explained as the strategy and form survival. 4. The theory of physiology, pathology and therapy in Sa-sang constitutional medicine can be hypothesized by the evolutionary standards which are related with the thermo-metabolism and hematopoietic-immune system.
Purpose This study was carried out ro apply the knowledge of bioinformatics to the quantification of constitutional information. Methods To objectify consitirutional knowledge, several uselful methods including Bayesian estimate, position specific score matrix, entropy, phylogenetic tree, simulated annealing were discussed. Results and Conclusion It is obvious that bioinformatic methods can be the most important tool for the objectification of constitutional medicine.
한국형발사체를 독자개발하기 위한 연구개발이 한국항공우주연구원을 중심으로 2010년 이후 수행 중에 있다. 발사대 장비 중 발사체고정장치는 발사체를 발사패드 위에 수직으로 기립시킨 후 발사체 하부를 고정하여 풍하중 등 외부 하중으로부터 발사체를 견고하게 고정하는 장치로, 발사체 1단 엔진 점화 후 발생된 추력이 발사체의 이륙중량을 초과되어 이륙이 시작하는 발사초기에 다른 지상장비들과 마찬가지로 발사체 이륙에 간섭이 되지 않도록 고정장치를 빠르게 해제 하여야 한다. 파이로밸브는 발사체고정장치를 구성하는 핵심 구성품의 하나로 발사체 단분리 장치 및 위성 분리장치 등에도 적용하는 유사기능부품으로 높은 신뢰도과 빠른 응답특성을 가져야 한다. 본 논문내용을 통해 발사체고정장치용 파이로밸브 개발과정과 한국형발사체에 대한 전반적인 이해의 폭을 넓히고자 한다. KARI has been conducting R&D for independent development of KSLV-II since 2010. Vehicle holding device is a device for vertically standing SLV on the launch pad of launch complex and fixing the lower part of vehicle in order to firmly fix vehicle so that SLV does not fall from an external load such as a wind load. When thrust generated after the 1st stage engine ignition of SLV must exceed the takeoff weight of vehicle, and holding device should be quickly released so that it does not interfere with takeoff of vehicle like other ground equipment at the beginning of the launch. Pyro-valve is one of the key components constituting VHD, and it should have high reliability and quick response characteristics with similar functional parts applied to launch vehicle separation device and satellite separation device. Through this paper, I intend to broaden the overall understanding of the development process of pyro-valve for VHD and KSLV-II .
The aim of this study is to compare the properties of odontoblast gene of early passage cells and late passage cells derived from impacted maxillary supernumerary teeth. Impacted supernumerary teeth with maxilla were extracted from 12 patients (8 males, 4 females) between 6 - 9 years old without medical history. Real-time polymerase chain reaction (PCR) was conducted to compare characterization of odontoblast cell in the 3rd and 10th passage, and between with bone inducing additive group and without additive group. Genes for odontoblasts characteristics are osteonectin (ONT), alkaline phosphatase (ALP), osteocalcin (OCN), dentin matrix protein 1 (DMP-1) and dentin sialophosphoprotein (DSPP). The level of gene expression was in a decreasing order of ONT, ALP, OCN, DMP-1 and DSPP in the 3rd passage, and in decreasing order of ONT, DMP-1, OCN, ALP, and DSPP in the 10th passage in the undifferentiation and differentiation group. The order of ONT, DMP-1, and OCN did not changed. ALP and DMP-1 were switched in order. ALP and DMP-1 may be used as important markers for differentiating between the 3rd passage and 10th passage cells. Considering that supernumerary tooth was extracted young age and the time required to cultured 10th passage was short, supernumerary tooth can be considered a useful donor site of dental pulp stem cells.
