Objective : The purpose of this report is to examine the effects of direct moxibustion in the Low back pain patient. Methods : Clinical studies were done 30 patients who were treated with low back pain to Dept. of Acupuncture & Moxibustion, of Oriental Medical Sang-Ji University from September 1, 2003 to August 31, 2004. We treated them by Oriental medical therapy(including direct moxibustion)for 10 days. The evaluation was performed five times(admission day, before and after each twice). Results : 1. VAS was decreased after direct moxibustion for 10 days significantly(p<0.01). 2. After direct moxibustion, S.L.R. T angle of patients were increased. ConclUsions : We brought to the conclusion that direct moxibustion has possibility to the efficient to cure the Low back pain. So we suggest the possibility to use this treatment for Low back pain.

<P>Background: The response of hepatocellular carcinoma (HCC) to immunotherapy is often disappointing and new strategies are clearly needed. The aim of the present study was to investigate whether cytokine-induced killer (CIK) cells combined with a dendritic cell vaccination enhanced cytotoxicity against hepatocarcinoma tumor cells in an in vivo animal model.Methods: CIKs and DCs were prepared from C3H/HeJ mice by conventional methods, the dendritic cell (DC) pulsed with a MH134 cell lysate, DC or CIK alone were used as controls. Cell phenotypes were analyzed by flow cytometry, cytokine secretion levels were determined by enzyme-linked immunosorbent assay (ELISA), and cytotoxicity was assessed by means of an in vitro lactate dehydrogenase (LDH) release assay. A mouse hepatocarcinoma cell MH134-bearing mice model was established to test the in vivo anti-tumor efficacy of the system.Results: CIK cells combined with DC therapy resulted in significant inhibition of tumor growth compared with the control group, whereas the decrease in tumor growth in mice that had been treated with CIK or DC alone did not reach the level of statistical significance. The combination therapy led to a further increase in the population of cytotoxic T cells (CTLs) in vivo, compared to the CIK or DC alone therapy. In addition, the combination therapy significantly enhanced cytotoxic activity against MH134 cells.Conclusion: Taken together, these results show that a DC + CIK vaccination is more effective than DC or CIK alone therapy for the treatment of hepatocarcinoma cancer.</P>

Laparoscopic surgery and the market for its robotic devices keep growing since postoperative complications are fewer and patients recover quicker than conventional laparotomy wounds, even though robotic surgery is 5-6 times more expensive than traditional laparotomy. We are developing surgical robot system with minimally invasive robotic surgical tools. And to use those tools in surgery, the mechanism of system needs to be simple and durable to reduce the cost of robotic surgery. In this paper, we present some mechanisms for minimally invasive surgical robot tools that have simple structure, easy to manufacture and control.

To ensure the international competitiveness of the domestic offshore plant industry, a consensus has been formed regarding the requirement for large offshore basins for performing offshore plant performance verification. Accordingly, the Korea Research Institute of Ships & Ocean Engineering has built the world"s largest deep ocean engineering basin (DOEB). The purpose of this study is to evaluate the characteristics of velocity distribution under various conditions of the DOEB. An independent measuring jig is designed and manufactured to measure the current velocities of many locations within a short time. The measurement jig is a 15-m-high triangular-truss structure, and the measurement sensors can move 15 m vertically through an electric motor-wire device. The current speed is measured under various impeller revolutions per minute and locations of the DOEB using the jig. The spatial distribution characteristics of the current velocity in the DOEB and the performance of the current generator are analyzed. The maximum speed is 0.56 m/s in the center of the DOEB water surface, thereby confirming sufficient current velocity distribution uniformity for model testing.
IMPACTION OF PRIMARY TEETH ASSOCIATED WITH ODONTOMA: CASE REPORTS
Jung-Woo Kim,Teo-Jeon Shin,Hong-Keun Hyun,Young-Jae Kim,Jung-Wook Kim,Ki-Taeg Jang,Chong-Chul Kim,Sang-Hoon Lee 大韓小兒齒科學會 2012 大韓小兒齒科學會誌 Vol.39 No.1
Odontomas generally appear as small, solitary, or multiple radio-opaque lesions found on routine radiographic examinations. It is a comparatively common odontogenic tumor, and may lead to interfere with the eruption of its associated tooth. In general, odontomas occur more often in permanent dentition and are very rarely associated with primary teeth. This report deals with five rare cases of primary teeth impaction associated with odontomas, with spontaneous eruption occurring in all five cases after simple surgical removal of the odontoma. Impacted primary teeth may be associated with defects in development and eruption of their permanent successors, and thus long-term observation is necessary until the permanent successors erupt. 치아종은 유치나 영구치배의 지속적인 치배 형성이나 법량기 세포들의 비정상적인 증식의 결과로 발생하는 방사선 불투과성 병소로, 비교적 흔한 치원성 종양이며 인접한 치아의 맹출을 방해 할 수 있다. 치아종은 영구치열기에서 주로 관찰되고, 유치열기에서는 매우 드문 것으로 보고되고 있다. 본 증례 보고에서는 치아종에 의해 매복된 유치가 치아종의 외과적 발거 후 자연 맹출된 증례들을 보고하고자 한다. 매복 유치는 계승 영구치의 발육과 맹출 문제를 야기할 수 있기 때문에 치아종이 제거된 후에도 계승 영구치가 맹출할 때까지 장기적인 검사 및 관찰이 필요하다.
A scalable hybrid approach for extracting head components from Web tables
Jung, Sung-Won,Kwon, Hyuk-Chul IEEE 2006 IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERIN Vol.18 No.2
We have established a preprocessing method for determining the meaningfulness of a table to allow for information extraction from tables on the Internet. A table offers a preeminent clue in text mining because it contains meaningful data displayed in rows and columns. However, tables are used on the Internet for both knowledge structuring and document design. Therefore, we were interested in determining whether or not a table has meaningfulness that is related to the structural information provided at the abstraction level of the table head. Accordingly, we: 1) investigated the types of tables present in HTML documents, 2) established the features that distinguished meaningful tables from others, 3) constructed a training data set using the established features after having filtered any obvious decorative tables, and 4) constructed a classification model using a decision tree. Based on these features, we set up heuristics for table head extraction from meaningful tables, and obtained an F-measure of 95.0 percent in distinguishing meaningful tables from decorative tables and an accuracy of 82.1 percent in extracting the table head from the meaningful tables.

Understanding how future climate conditions will be impact on the biodiversity and species composition is important, because biodiversity becomes more important in environment assessment. To understand the biological changes including diversity and species composition over time (temporal variation within a year), the species diversity and composition of ground beetles were investigated in two well-preserved areas in the Sobaeksan National Park using pitfall traps. In addition, relationships between ground beetles and environmental variables were studied by considering temporal variation. We collected 2,146 ground beetle specimens representing 45 species, and individual-based rarefaction curves indicated that similar species richness was found between Geumseon Valley (GV) and Namcheon Valley (NV). The Bray-Curtis matrix comparisons between study sites were characterized by similar ground beetles sample heterogeneity, while temporal variations in abundance, species richness, and ${\beta}-diversity$ of ground beetles showed rather difference over time according to location of study sites. In GV site, minimum temperature was selected as the best predictor for abundance, species richness, and ${\beta}-diversity$ of ground beetles, while those relationships in NV site were more complicated. In conclusion, our study suggests that understanding the different response of ground beetles to climatic variables related to local habitat conditions is important to predict the effect of climate change on biological communities.
