기능성 반대교합을 가진 성장기 환자의 경우 조기에 원인을 제거하여 골격성으로 이행하는 것을 방지하고 성장조절에 의해 악골관계를 개선함으로써 정상적인 기능과 안모를 유도해야 된다. 반대교합의 치료방법중 기능형 치료장치가 있는데, 그중 Frankel 장치물은 작용발휘의 기반으로서 vestibular region을 이용하는 것이 특징이며, 비정상적인 근육력을 차단하여 구강내 치열 및 악궁에 대한 힘의 불균형 상태를 개선하고, 결여되어 있는 근육의 긴장도를 증대시킴으로써 근육의 힘을 치아에 직접 미치지 않고, 악골 및 치아, 치조골을 양호하게 발육시킬 수 있다는 점에서 근육의 힘이 장치를 매개로하여 직접 치아에 전달되어 치아이동을 얻게 되는 다른 장치와 구별된다고 할 수 있다. 이에, 상악중절치 맹출시기의 전치부 반대교합을 FR Ⅲ로 치료하여 다음과 같은 결론을 얻었다. 1. 상악의 전방성장과 상악전치의 순측경사가 일어났다. 2. 하악의 후하방회전에 의해 하안면고가 증가하였다. 3. 정상적인 하악골과 열성장된 상악골을 가진경우, 수직피개교합과 역수평피개교합이 더 클수록 더 좋은 예후를 나타냈다. It is well recognized that a cross-bite tends to occur more frequently among Japanese, Chinese and Koreans more than among Europeans. A variety of functional appliances have already invented for the treatment of cross-bites. One of them is the FR Ⅲ(by Rolf Frankel) which applies a quite different philosophy based on the using vestibular region compared with other methods which utilize muscular forces applied directly on the teeth. The FR Ⅲ also increases both the lack of muscular tension against the dental arch and the dentition and muscular forces which can then influence the teeth indirectly. This mechanism can achieve favorable developments with the basal bone, teeth, and alveolar bone. After using FR Ⅲ to the anterior cross-bite patient with the eruption of a maxillary incisor, the results were as follows: 1. Forward growth of maxilla and proclination of the upper incisor 2. Downward and backward rotation of the mandible 3. Increase the facial height 4. The case which was normal mandible, underdevelopmental maxilla, deeper overbite and more nagative overjet exhibited good prognosis

QUOTIENTS OF REAL ALGEBRAIC G VARIETIES AND ALGEBRAIC REALIZATION PROBLEMS

SUN, DONG YOUP 경북대학교 위상수학 기하학연구센터 1995 硏究論文集 Vol.4 No.-

Let G be a compact Lie group and H an odd order group. We show that a real algebraic G×H variety X induces a real algebraic G variety structure on the quotient space X/H. We then apply the result to actions with one orbit type to solve algebraic realization problems for both G manifolds and G vector bundles.

An algorithm to automatically extract coordinate and time information from optical observation data of geostationary orbit satellites (GEO satellites) or geosynchronous orbit satellites (GOS satellites) is developed. The optical wide-field patrol system is capable of automatic observation using a pre-arranged schedule. Therefore, if this type of automatic analysis algorithm is available, daily unmanned monitoring of GEO satellites can be possible. For data acquisition for development, the COMS1 satellite was observed with 1-s exposure time and 1-m interval. The images were grouped and processed in terms of “action”, and each action was composed of six or nine successive images. First, a reference image with the best quality in one action was selected. Next, the rest of the images in the action were geometrically transformed to fit in the horizontal coordinate system (expressed in azimuthal angle and elevation) of the reference image. Then, these images were median-combined to retain only the possible non-moving GEO candidates. By reverting the coordinate transformation of the positions of these GEO satellite candidates, the final coordinates could be calculated.

Ethephon was sprayed on Euphorbia pulcherrima Willd. ex Klotzsch (poinsettia) ‘Sonora Jingle’ and ‘Sonora White’ to control their height and produce more compact potted plants. The results showed that Ethephon could effectively control the growth of ‘Sonora Jingle’ and ‘Sonora White’ poinsettia. Height was reduced by was 33.4 ± 0.8% for ‘Sonora Jingle’ and 30.8 ± 1.3% for ‘Sonora White’ poinsettia, when 700 mg・L^(-1) Ethephon was sprayed three times on 29 August, 20September, and 13 October 2005, respectively. Similar to other plant growth retardants, side effects including phytotoxicity and delays to first bract color were also observed on Ethephon treated poinsettia. However, all plants produced were still of a marketable quality.

Development of a Data Reduction algorithm for Optical Wide Field Patrol

Park, Sun-Youp,Keum, Kang-Hoon,Lee, Seong-Whan,Jin, Ho,Park, Yung-Sik,Yim, Hong-Suh,Jo, Jung Hyun,Moon, Hong-Kyu,Bae, Young-Ho,Choi, Jin,Choi, Young-Jun,Park, Jang-Hyun,Lee, Jung-Ho 한국우주과학회 2013 Journal of Astronomy and Space Sciences Vol.30 No.3

The detector subsystem of the Optical Wide-field Patrol (OWL) network efficiently acquires the position and time information of moving objects such as artificial satellites through its chopper system, which consists of 4 blades in front of the CCD camera. Using this system, it is possible to get more position data with the same exposure time by changing the streaks of the moving objects into many pieces with the fast rotating blades during sidereal tracking. At the same time, the time data from the rotating chopper can be acquired by the time tagger connected to the photo diode. To analyze the orbits of the targets detected in the image data of such a system, a sequential procedure of determining the positions of separated streak lines was developed that involved calculating the World Coordinate System (WCS) solution to transform the positions into equatorial coordinate systems, and finally combining the time log records from the time tagger with the transformed position data. We introduce this procedure and the preliminary results of the application of this procedure to the test observation images.

Due to its carbon-neutral nature, biogas generated from anaerobic digestion or fermentation of biodegradable wastes is one of the important renewable energy sources to reduce global warming. It is mainly composed of methane and various inert gases such as CO2 and N2, and the actual composition of biogas significantly varies depending on the origin of anaerobic digestion process. Therefore, in order to effectively utilize this fuel as an energy source for electricity, it is important to develop power generation engines which can successfully apply biogas with significant composition variations. In this study, efforts have been made to develop a diesel-biogas duel fuel engine as a way to achieve such a stable power generation. The effects of diesel fuel injection quantity and pressure on stable combustion and engine performance were investigated, and an impact of diesel fuel atomization was discussed. The engine test results show that there exists a 2 stage combustion which consists of diesel pilot fuel burning and premixed biogas/air mixture burning in dual fuel engine operation and optimum diesel injection parameters were suggested for biogases with various compositions and heating values.

<P>The identification of novel tumor-specific proteins or antigens is of great importance for diagnostic and therapeutic applications in pancreatic cancer. Using oligonucleotide microarrays, we identified a broad spectrum of differentially expressed pancreatic cancer-related genes. Of these, we selected an overexpressed expressed sequence taq and cloned a 721-bp full-length cDNA with an open reading frame of 196 amino acids. This novel gene was localized on the Homo sapiens 16p13.3 chromosomal locus, and its nucleotide sequence matched the Homo sapiens similar to common salivary protein 1 (LOC124220). We named the gene pancreatic adenocarcinoma up-regulated factor. The pancreatic adenocarcinoma up-regulated factor was secreted into the culture medium of pancreatic adenocarcinoma up-regulated factor-overexpressing Chinese hamster ovary cells, had an apparent molecular mass of approximately 25 kDa, and was N-glycosylated. The induction of pancreatic adenocarcinoma up-regulated factor in Chinese hamster ovary cells increased cell proliferation, migration, and invasion ability in vitro. Subcutaneous injection of mice with Chinese hamster ovary/pancreatic adenocarcinoma up-regulated factor cells resulted in 3.8-fold greater tumor sizes compared to Chinese hamster ovary/mock cells. Reverse transcription-polymerase chain reaction and western blotting with antirecombinant human pancreatic adenocarcinoma up-regulated factor antibodies confirmed that pancreatic adenocarcinoma up-regulated factor was highly expressed in six of eight pancreatic cancer cell lines. Immunohistochemical staining of human pancreatic cancer tissues also showed pancreatic adenocarcinoma up-regulated factor overexpression in the cytoplasm of cancer cells. Transfection with pancreatic adenocarcinoma up-regulated factor-specific small-interfering RNA reduced cancer cell migration and invasion in vitro. Treatment with antirecombinant human pancreatic adenocarcinoma up-regulated factor in vitro and in vivo reduced proliferation, migration, invasion, and tumorigenic ability. Collectively, our results suggest that pancreatic adenocarcinoma up-regulated factor is a novel secretory protein involved in pancreatic cancer progression and might be a potential target for the treatment of pancreatic cancer.</P>
