Rhabdomyosarcoma, when it occurs in the head and neck, is primarily found in children. Alveolar rhabdomyosarcoma is rarely seen in the oral lesion, comparing to the embryonal and the pleomorphic variants. This is a report of a case of alveolar rhabdomyosarcoma in the mandible in a ten-year old girl who complained of a non-painful swelling on the right cheek. The right lower 1st molar was mobile. Her radiographs revealed an extensive radiolucency with somewhat irregular border on the right mandibular ramus. The right mandibular 1st and 2nd molars lost their lamina dura and were floating. CT images revealed smooth-outlined soft tissue mass occupying the pterygomandibular space, the infratemporal space, and the masseteric muscle with thinning and perforation of the right mandibular angle and ramus. Histopathological and immunohistochemical findings established the final diagnosis of alveolar rhabdomyosarcoma.

This research is to comparative study on the physique and the physical fitness and the obesity of the Regions that S middle school which is located in Seoul, which are 172 students(90 boys, 82 girls) and that 84 boys from A middle school, 74 girls from F middle school also located in Chungnam. totally 330 students. Then after we got the result we compared the result with the average of examination of the physical fitness for whole students reported by the Ministry of Education and Human Resour Development. Obtain the result follow: First, in the structure of physique, The Seoul area students appeared the Chungnam area students compared to 4.2cm height and 2.7kg weight highly. The Seoul area girls students who was higher 1.4cm and lower weight 0.6kg, than Chungnam area girl students. In the physical fitness, the average figures of boys in Chungnam are higher than the average figures of boys in Seoul in a standing long jump, a push-up, sit-ups, sit and reach. the average figures of girls in Chungnam was higher than the average figures of girls in Seoul in a standing long jump, fixed-arm hanging and a long distance race. Second, in the structure of physique fitness the height and for boys and girls studnts Seoul and Chungnam girl students are higher than the national average. Weight was appeared highly seoul area man and two area girls students than the national average. In the physical fitness the students in Seoul have under average in all items except push-ups. And boys in Chungnam have higher result than the national average in sit-ups and sit and reach. In two area girls students, there was appeared more lowly the national average than from all items. Third, in the degree of obesity, A Seoul area boy students was under weight(0.5%) and hi degree of obesity(1.6%) than Chungnam area boys. A Seoul area girl studnts was low of over weight(5.6%) and hi degree of obesity(1.8%) than a Chungnam area girls

Regulation mechanisms of inflammatory responses induced by FcrR stimulation in human monocytes and monocytic cell line THP1 were investigated. Release of arachidonic acid, which is the precusor for inflammatory mediators, was induced by FcrR stimulation with its ligand human IgG or with anti FcrR mAbs. This response was further increased when FcrR was cross-linked with in-soluble anti-IgG-agarose and soluble anti-IgG Fc specific Fab fragments. These phenomena were shown in both monocyte and THP1. Oxidative burst activity, resulting from generation of reactive oxygen speices, was also induced by FcrR stimulation and further enhanced by cross-linking of Fcr R. Induction mechanisms of inflammatory responses caused by PMA or FcrR stimulations were then examined by measurements of release of arachidonic acid and oxidative burst activity. The results demonstrate that monocytes utilize different signaling pathways for FcrR or PMA stimulation. Signaling mechanism of PMA stimulation is especially dependent on Ca}+/calmodulin dependent kinase in arachidonic acid release, but not in oxidative burst activity. Meanwhile, signaling pathways of FcrR are dependent on tyrosine kinase but independent of protein kinase C both in the release of arachidonic acid and oxidative burst activity. The results suggest that in monocytes, there is a not only functional but also mechanistic link between arachidonic acid release and oxidative burst activity induced upon FcrR stimulation. Distinct signaling pathways seem to be operating in transformed monocytic cell line THP-1 cells, and no mechanistic link was found between arachidonic acid release and oxidative burst activity induced after FcrR stimulation.

Purpose: This study was aimed to specify roles of nurses from the anesthesia and recovery room by analyzing nursing activities as well as anesthesia nursing during surgery. Method: The objects were 12 RNs working in the recovery room of a university hospital located in Incheon. Self-report was performed by measuring stop-watch for five days from May 17th to May 21st in 2004. Research method was designed to record the time and frequency of the nursing activity from anesthesia and recovery room based on nurses' statement and other references for five days. The data were analyzed with descriptive statistics, ANOVA, and t-test via SPSS Win 10.0 program. Result: Nursing activities in anesthesia recovery room were classified into two different characteristics such as direct and indirect nursing activity. The activities consisted of 11 direct nursing areas and 39 nursing activities in anesthesia preparation room. The indirect nursing was classified into 8 nursing areas and 32 nursing activities. The direct nursing was classified into 12 nursing areas and 55 nursing activity. Also, the indirect nursing was classified into 7 nursing areas and 21 nursing activities in recovery room. In terms of prevalence of nursing activities in the anesthesia preparation room, observation and cooperation of anesthesia was the most prevalent activity, drug and eqipment management the second prevalent, and drug administration the third. On the other hand, in the recovery room, the most prevalent activity was vital sign checking and observation, the second most prevalent activity informative activity, and the third body temperature control. Nursing activity time was recorded according to the nursing characteristics. In the anesthesia preparation room, the direct nursing spent for 8092.20 minutes was larger than the indirect nursing spent for 7198.50 minutes. Also, in the recovery room, the direct nursing spent for 2361.16 minutes was larger than the indirect nursing spent for 1134.13 minutes. 4. Nursing activity time was compared to duty shifts. In the anesthesia preparation room, the direct nursing was more prevalent on day shift and the indirect nursing was prevalent on evening shift. However, in the recovery room, both direct and indirect nursing activities were prevalent on day shift. Conclusion: The role of anesthesia and recovery room nurses was analysed according to the time, frequency, and its characteristics.

Penetration of concrete by aggressive materials in solution may cause an undesirable effect on concrete durability, for instance when Ca(OH)₂ is being leached out or an attack by aggressive liquids takes place. In particular, carbonation occurs in concrete because the calcium bearing phases present are easily attacked by carbon dioxide and converted to calcium carbonate from surface of concrete, It has been known that the durability of reinforced concrete structure is concerned with the surface performance of concrete which affects on the carbonation occurred by invasion of CO₂ gas and the corrosion of steel bar occurred by O₂ In this paper, the effects of carbonation resistance by improvement of surface performance for concrete are investigated according to the accelerated carbonation test. It is believed that the carbonation resistance of concrete has been significantly improved by the application of penetrative hardening agent due to the formation of a dense surface.
