Authors report a case of one-stage transoral decompression and posterior fusion in rheumatoid atlantoaxial subluxation. A 63-year-old man developed a rheumatiod atlantoaxial subluxation with mild weakness of all extremities which developed relatively suddenly 3 months after the initial symptom of neck pain. Skeletal traction followed by transoral decompression and occipitocervical fusion was performed on the same day. Postoperative course has been uneventful and revealed favorable fusion state of occipito-atlanto-axis. The pertinent literature on theumatoid atlanto-axial subluxation is reviewed and discussed.

Beta-Alumina was prepared with varying Na content from the theoretical composition of β-Al₂O₃(Na₂O·llAl₂O₃) to that of β″-Al₂O₃(Na₂O·5Al₂O₃). Phases and electrical properties of specimens have been investigated. For specimens sintered at 1600℃ for 30mins, Majority phase is β-Al₂O₃and when Na₂O content is over 7.98 wt%, β-Al₂O₃ phase only exists. However, for specimens sintered at 1600℃ for 90 mins, β-Al₂O₃ only is shown. For sintered β-Al₂O₃specimen with α-Al₂O₃, the resistivity is mainly affected by α-Al₂O₃, but for β-Al₂O₃specimen without α-Al₂O₃, it can be divided into part of three temperature regions by effect of grain boundary.

Cerebral angiography has been essential for the diagnosis of the intracranial aneurysms but. is sometimes accompanied by serious complications. Resolution of CT angiography was up-graded greatly to represent the three-demensional structure of vesseles since helical CT had been introduced. We have compared 26 cases of CT angiography and 28 cases of conventional angiography in terms of specificity and sensitivity for the diagnosis detectable aneurysm diameter. configurational diagnosis and diagnostic confidency. All results showed no statistical difference between CT angiography and conventional angiography. These should suggest that CT angiography could be replaced with conventional angiography for the diagnosis of ruptured aneurysms and even of unruptured aneurysms. resulting in the introduction of first screening modality of unruptured aneurysms.

The proper surgical management of obstructing left colorectal cancers in an issue of debate. Staged operation including proximal colostomy has generally been accepted as a safe and standard method of management. But staged colonic procedures are associated with significant morbidity and mortality, and many patients, unfit for further surgery, are left with a permanent colostomy. Many other methods such as the use of long intestinal tube, transanastomotic obturation balloon colostomy, intracolonic bypass tube (Coloshield) were developed, but they have failed to gain wide accepance. We have already reported the initial results of intraoperative antegrade colonic irrigation for one-stage operation in obstructing left colorectal cancers. In this investigation, we evaluated the results of prospective trials of primary resection and anastomosis using intraoperative colon irrigation and subtotal colectomy in obstructing loft colon and rectal carcinomas. During recent five years, 19 cases of obstructing left colon and rectal carcinomas which could not received regular colon preparation due to marked abdominal distension were enrolled to this study. There were 12 men and 7 women, and mean age was 61. 14 of the 19 patients which tumors located below mid-descending colon were subjected to primary resection and anastomosis using intraoperative antegrade colonic irrigation, 4 patients which tumors located above the mid-descending colon were treated with subtotal colectomy, and remaining one patient which tumor located upper rectum was performed subtotal coloectomy because of underlying colonic ischemia. There was no mortality and significant postoperative complications such as anastomotic leakage, pelvic abscess of intraabdominal sepsis which seemed to related with anastomotic dehiscence. Therefore, primary resection and anastomosis using intraoperative colonic irrigation of subtotal colectomy depending on tumor locations in cases of obstructing left colon and rectal carcinomas might be useful methods to obtain safe one-stage restorative colorectal resections

The systematic material management of curtain wall should be established on accomplished EVM data. The matrix method of integrated cost and schedule was used with common category concept according to the construction project control system. The material management was suggested through analyzing curtain wall process and data model using integrated cost, schedule and material. In this study, the material management of curtain wall based on historical data to the related EVM is proposed. This Material management of curtain wall model can provide a standard process and data which are related to the integrated cost, schedule data.

Major cardiovascular complications of diabetes are coronary atherosclerosis, diabetic dilated cardiomyopathy, autonomic neuropathy and those are major causes of morbidity and mortality in diabetic patients. Gated blood pool heart scan is noninvasive and useful method for evaluation of functional status of heart in diabetics. We evaluated 52 patients with diabetes and divided 3 groups. Group 1 were 11 patients without proteinuria or with proteinuria less than 550mng during 24 hours. Group 2 were 9 patients with proteinuria more than 550mg during 24 hours and group 3 were 32 patients with endstage renal diasese due to diabetes. We performed 99mTc-HSA cardiac gated blood pool scan and used left ventricular ejection fraction(LVEF), peak ejection rate(PEF) to indices of LV systolic function and peak filling rate(PER) to index of LV diastolic function. The results were follows : 1) LVEF, PER were significantly lower in diabetics with ESRD than diabetics without ESRD, but there were no significant difference between normal controls and diabetics without ESRD 2) PFR was significantly lower in diabetics than normal controls, but there were no significant differences in diabetics with or without nephropathy. 3) There were negative correlation between PER, PFR and duration of diabetes. On the basis of results, PFR is a LV functional index of GBPS which can disclose early change of LV dysfunction in patients with diabetes.

The purpose of this study is that public kindergarten teachers and private kindergarten teachers perceive the kindergarten teachers' role and related degree of role importance, and as looking into what is difference recognition of kindergarten teachers and private kindergarten teachers . To achieve the study purpose, investigator choose the study method by the questionnaire. It consisted of 47 items reflecting the 6 areas of roles. To perform this study, In order to conduct this study we gave several test's to 135 public kindergarten teachers and 137 private kindergarten teachers in chunk-buk province by either in person or by mail, By using the SPSS/PC+ program it resulted to the T-test, the oneway ANOVA and the Tukey after inspection. The result of this study is as follows. 1. We discovered that public kindergarten teachers had a conscious recognition of the importance of their roles and had pride in what they wear Therefore the support for extension of specialization will lead into positive effiency for their roles performance as teachers. 2. Both public kindergarten teachers and private kindergarten teachers have a high recognition in the importance of kindergarten' roles which led into the sympathetic response to each other that they be closely connected with each other. 3. According to the related transformation cause. between the public kindergarten teachers and private kindergarten teachers group. kindergarten teachers role recognition has a little difference of related teacher's age and educational career.

It is necessary to provide sufficient daylighting for the high quality lighting in interior space. In these days various kinds of daylighting systems are developed and applied to buildings, however the difference of the purpose of an object room and a physical environment makes the Daylighting system to be unuseful. Therefore it is necessary to estimate the performances of the Daylighting system using the Computer program to apply the Daylighting system usefully. The purpose of this study is to develop the computer program using the Monte Calro Method and Ray-tracing technique to estimate the performances of the Daylighting system in interior space and the consumption of electric energy by dimming control of electric lighting. The accuracy of the computer model was validated through measurements with physical scale models under real clear sky conditions.
