Background p19arf, primarily known as a tumor suppressor, has also been reported to play an essential role in normal development of mouse eyes. Consistently, lack of p19arf has been associated with ocular defects, but the mixed background of the knockout (KO) mouse strain used raised a concern on the accuracy of the phenotypes observed in association with the targeted gene due to genetic heterogeneity. Object We carried out a study to investigate into the efect of genetic background on the manifestation of p19arf KO associated phenotypes. Methods We characterized the phenotypes of novel p19arf KO mouse lines generated in FVB/N and C57BL/6J using a transcription activator-like efector nuclease (TALEN) system in comparison to the reported phenotypes of three other p19arf-defcient mouse lines generated using homologous recombination. Results Ninety-fve percent of FVB/N-p19arf KO mice showed ocular opacity from week 4 after birth which worsened rapidly until week 6, while such abnormality was absent in C57BL/6J-p19arf KO mice up to the age of 26 weeks. Histopathological analysis revealed retrolental masses and dysplasia in the retinal layer in FVB/N-p19arf KO mice from week 4. Besides these, both strains developed normally from birth to week 26 without increased tumorigenesis except for a subcutaneous tumor found in a C57BL/6J-p19arf KO mouse. Conclusion Our fndings demonstrated surprisingly variable manifestation of p19arf-linked phenotypes between FVB/N and C57BL/6J mice, and furthermore between our mouse lines and the established lines, indicating a critical impact of genetic background on functional study of genes using gene targeting strategies in mice.

Magnesium carbonate hydroxide (hydrotalcite) was synthesized to pursue the optimum conditions having the highest acid consuming capacity by a Box-Wilson experimental design, and micromeritical properties of samples were evaluated by laser particle size analyzer, SRD, BET system, mercury porosimeter, and several adsorption capacity test. The optimum preparation conditions for hydrotalcite were as followwws: concentration of aluminum hydroxide and magnesium hydroxide 1.17mole, reaction temp. 82.6℃, reaction time 2.32hr, ratio of (Al(OH)_3/Mg(OH)_2 4.25, drying temperature 93.2℃ respectively, and its acid consuming capacity was 286ml/g. the neutralization curve shows that sample whose acid consuming capacity was the highest has the best neutralizing capacity and duration capacity. The crystalline form of the synthesized hydrotalcite was identified with a hexagonal system, and the d (003) spacing value of three samples was large. a part of alumina crystal form was shown at 2θ=18°, 38° in sample 3. The micromeritical properties of the synthesized hydrotalcite has no relation with an acid consuming capacity, and there was a tendency that the higher the acid consuming capacity is the larger the particle size and the narrower the size distribution. The values of pore invasive volume, pore area and specific surface area of sample 1 were small among three samples. Isotherm by BET system forms hyteresis loop and it shows the synthesized hydrotacite was porous. the pore diameter was about 10Å and it verifies mesopore. The adsorption capacity measured by methylene blue has no relation with acid consuming capacity. The adsorption of quinine sulfate in aqueous solutuion was identical with the Langmuir isotherm.

This study considered the characteristics of Gian Lorenzo Bernini's inclusive architecture by means of the iconological interpretation of the relationship between his architecture and sculpture. There have been many studies of Bernini's sculpture and architecture apart, and it is the fact that especially studies of his architecture have remained at stylistic one. However it is not so much difficult to find the ensemble made by symbolic relationship between architecture and sculpture in Bernini's works. Therefore this study introduced Erwin Panofsky's Iconology methodologically to analyze his architectural works and to show that they could be interpreted from sculpture added to architecture. According to iconological analyses about Bernini's Sant' Andre al Quirinale and Scala Regia, followings were investigated. Firstly, The sculptures added to each architectural space are not simple baroque decorations but project symbolic meanings such as the religious symbolism, the historicity of site, and the needs of the time. Secondly, each architecture and sculpture organize spatial characteristics in harmony by means of the projected symbolic meaning. Thirdly, the motive which make him add many sculptures to architectural space are neo-platonism, city planning of Baroque, and political reasons which reinforce the papacy.

Background : Various types of protective footwear have been used to minimize bacterial contamination in operating rooms. In recent years, debate has arisen concerning the need for use of such protective footwear. This study was designed to provide useful data about choosing shoes most suitable for the surgical environment. Methods : Between November, 1999 and January, 2000, we performed this experimental study by comparing effect of three types of shoes (i.e., disposable shoescover, operating room-restricted shoes, and ordinary shoes) on bacterial contamination of operating rooms equipped with two different ventilation systems (i.e., high air-change, low air-change) respectively. Data were collected during two-hour sham operations in which subjects and their activities were strictly standardized. Bacterial flora were sampled from the study area floor and air colony-counts were measured. Results : In experiments involving high air-change ventilation system, there was a significant difference of floor contamination between three types of shoes, but no difference of air contamination. Under low air-change system, there was a significant difference of both floor and air contamination between three types of shoes. Conclusion : The results show that protective footwear would be unnecessary in the operating room with high air-change ventilation system, but it is important to choose suitable shoes carefully under low air-change system. Therefore, the use of outdoor shoes can be considered under high air-change system, but it would seem sensible to apply their first use in less bloody operations at the day surgery center or out-patient department to prevent transfer of body fluid into the outside environment.

The studies about automatic pattern detection of the eye and face from the human image acquired by the CCD image sensor have good applicabilities in the industry, home automation, and data communication field. In general, pattern detection method consists of feature based matching and template matching. In feature based matching, the feature vector is extracted with DLM(dynamic linking matching), EBGM(elastic bunch graph matching), HMM(hidden markov model) matching and knowledge based matching using statistical characteristics. In template matching, in general, the template vector is extracted with PCA(principal component analysis). When these method applied in the face and eye detection, each method has its own merits and some disadvantage. Therefore, by combined utilization of SVD(singular value decomposition) and HMM algorithm, is expected that we can selectively make use of each methods advantage and it result in improved detection accuracy. In this paper, we proposed the method for face and eye detection, which was combined by the two algorithms, to be suitable for the high speed image processing using DSP chip or microprocessor. In the beginning, template matching was followed by a template extraction using batch SVD algorithm and then face pattern was classified and recognized by HMM algorithm which is one of feature based matching technique. Finally, eye pattern detection was performed by pattern search neural network utilizing eigeneye image.

강동균,황경문,김은정,김현정,김영진,남순현 大韓小兒齒科學會 2006 大韓小兒齒科學會誌 Vol.33 No.1

하마종은 구강저에 발생하는 점액 남종으로 주로 설하선과 관련된다. 즉, 하마종은 설하선 분비도관의 파열로 인하여 타액이 분비도관에서 빠져나와 주위의 연조직 내에 저류됨으로써 발생하는 가성 낭으로 정의 되며, 원인은 설하선 도관의 파열이나 폐색이다. 하마종의 임상소견은 청색의 투명한 종창이 구강저의 소대를 중심으로 편측으로 발생하며, 무통성이며, 촉진시 파동성을 나타낸다. 조직소견은 결합 조직 내 와동이 형성되지만, 낭 벽은 상피세포가 아닌 육아조직으로 구성되는 가성 낭을 관찰할 수 있다. 하마종의 첫 번째 치료법으로는 하마종의 내벽이 구강점막의 일부가 되도록 만들어 주는 조대술을 고려할 수 있다. 본 증례는 특징적인 하마종의 임상소견을 보이는 환아에게 gauze-packing등을 동반한 조대술을 이용하여 치료한 증례로써 양호한 치료결과를 보여 보고하고자 한다. Ranula is a mucocele which occurs at the mouth floor and mostly related to sublingual gland. In other words ranula is definded as a pseudocyst which occurs as the secretion duct of sublingual gland is destructed there as the saliva from the the secretion duct flows out and retention in the soft tissue. The cause of ranula is destruction or obstruction of the duct. The clinical findings of ranula is a painless, unilateral bluish transparent swelling around the frenum and shows fluctuation when palpated. Histological finding represent a formation of cavity inside the connective tissue. but a pseudo-cyst can be seen which the wall of the cyst is composed of granulation tissue rather than epithelial cells. The first treatment of ranula can be considered as marsupialization. which induces the inner wall of the Ranula to be a part of oral mucosa. This case report shows a treatment of marsupialization with gauze packing in a young patient representing a clinical finding of characteristic ranula.
