Purpose: The purpose of the study was to forecast manpower by building the nursing manpower-staffing model(surgical-medical nursing unite). Method: The system dynamics approach was adapted to build a simulation model for calculating medical-surgical nursing manpower-staffing. The model was built up on Venism 5.0b DSS. Result: The results in the basic circumstance are in following. The level of nursing service quality, patientsatisfaction, and nurse job satisfaction maintains higher at medical-surgical nursing unit of the tertiary hospitals with the ratio of bed to nurse 2.5:1-3.0:1 than at any other situations. The level of nursing service quality, patient satisfaction, and nurse job satisfaction maintains higher at madical nursing unit of the secontary hospotals with the ratio of bed to nurse 3.0:1 and at surgical nursing unit of the secondary hospitals with the ratio of bed to nurse 3.0:1-3.5:1 than at any other situations in the fundamental from. The results in the simulation circumstance are in following, As author raises the operating rate of bed into 95-100%, and cut skilled nursing staff down, the level of nursing-service quality, patient satisfaction, and nurse job satisfaction drops slightly. Conclusion: In terms of economic efficiency on tertiary hospotals, the ratio of bed to nurse for the best reasonable medical-surgical nursing manpower-staffing is 3.0:1. In terms of economic efficiency on secondary hospitals, the ratio of bed to nurse for the best reasonable medical nursing manpower-staffing is 3.0:1 and surgical nursing manpower-staffing is 3.5:1

Recently, the impotence of participating in classes actively and cultivating student's thinking ability is emphasized in mathematics education society. Teachers are demanded to change their teaching style centered pencile- and-paper into using the variety instructional aids, such as calculator, vidio tape, computer, ohp, and projector, etc. In this paper, we search for the maple's function and the method that apply maple to the secondary school mathematics Maple has many functions : calculator, algebra, graphics, animation, programing, notebook. We find that maple can be applied to the graph of function, the understand of simultaneous equations, the graph of trigonomtry function, the calculation of limit, the computation of areas as limits, the derivative of a function and tangent line, a solid figure, and others in secondary school mathematics.

It is very difficult to test the concrete quality, because the concrete consists of various materials, such as cement, sand, gravel, water, and etc. Therefore, the concrete has difficulties to estimate quickly its quality, compared with the other materials, Accordingly, we can't reflect quality control result quickly, a fresh concrete has many serious problems (economical problem, structural problem, etc.) after being cast in place. Especially, it takes a long time to discover the problems so that it's difficult to consider a counterplan when we discover them. And it takes not only many cost to Solve those problems, but we can't also remove perfectly fundamental ones. Besides, it results in shortening a whole building life, nevertheless the damage is small and limited. Therefore, the earlier test system of concrete quality is needed for the solution of the problem. The purpose of this study is to develop the method of earlier concrete quality control and its system, which evaluate the concrete 28 days strength in concrete. And this study establishes the general equation for the prediction of 28 days strength from the results of the earlier test. Also the method adopted ultras-onic velocity and electric resistivity as specific characters. This study proposed the method, the general equation, and the system for earlier concrete strength evaluation so that we may achieve convenient and quick quality controls.

During the prostate cancer (PCa) development and its progression into hormone independency, androgen receptor (AR) signals play a central role by triggering the regulation of target genes, including prostate-specific antigen. However, the regulation of these AR-mediated target genes is not fully understood. We have previously demonstrated a unique role of HOXB13 homeodomain protein as an AR repressor. Expression of HOXB13 was highly restricted to the prostate and its suppression dramatically increased hormone-activated AR transactivation, suggesting that prostate-specific HOXB13 was a highly potent transcriptional regulator. In this report, we demonstrated the action mechanism of HOXB13 as an AR repressor. HOXB13 suppressed androgen-stimulated AR activity by interacting with AR. HOXB13 did neither bind to AR responsive elements nor disturb nuclear translocation of AR in response to androgen. In PCa specimen, we also observed mutual expression pattern of HOXB13 and AR. These results suggest that HOXB13 not only serve as a DNA-bound transcription factor but play an important role as an AR-interacting repressor to modulate hormone-activated androgen receptor signals. Further extensive studies will uncover a novel mechanism for regulating AR-signaling pathway to lead to expose new role of HOXB13 as a non-DNA-binding transcriptional repressor.
Calibrating KOMPSAT OSMI sensor using in situ measurements

A vicarious calibration method was developed for an OSMI sensor calibration using sky radiometer measurements and observed water leaving radiances as inputs to a radiances transfer model. Observations of these input data were made during a cruise from April 16 to April 23, 2001 in the East Sea, while two KOMPSAT overpasses were made. TOA (top of the atrnosphere) radiance for each OSMI channel was calculated. Calibration coefficients are determined at six OSMI channels by comparing calculated TOA radiances with OSMI count values.

<P>Conclusions: Skull-base tumor surgery via an EETSA with a team approach was performed for various extended tumors. It is important to consider postoperative sinonasal dysfunction, such as hyposmia or anosmia, and to have this followed by an otolaryngologist.</P>

<P>Conclusion: This technique could improve the manipulability of surgical instruments and increase the accessibility of the parasellar region. This approach better conserves the nasal mucosa, posterior ethmoid, and superior and supreme turbinates and more efficiently exposes skull-base tumors than traditional methods with pathology of the anterior cranial fossa and parasellar region. This technique also prevents the drilling procedure from damaging the surrounding nasal mucosa, including the exfoliated and laterally preserved posterior sphenoid mucosa.</P>

<P>Objective We evaluated postoperative changes in nasal cavity dimensions and their effects on nasal functions and symptoms. Study Design Case series with chart review. Setting Tertiary referral center. Subjects and Methods We studied patients who underwent binostril, 4-hand endoscopic endonasal transsphenoidal approach surgery with the bilateral modified nasoseptal rescue flap technique. Pre- and postoperative paranasal computed tomography scans were used to assess nasal cavity dimensional changes at 4 levels. We also performed several pre- and postoperative tests, including the Connecticut Chemosensory Clinical Research Center test and the Cross-Cultural Smell Identification Test (n = 119) to evaluate olfactory functions. Also, the Nasal Obstruction Symptoms Evaluation, the Sino-Nasal Outcome Test-20, and a visual analog scale were used (n = 157) to record subjective symptoms. We compared these data with the pre- and postoperative nasal cavity dimensions. Results Two-dimensional objective increases in nasal passage dimensions were evident postoperatively (all cross-sectional areas, P < .001, except choana and left inferior turbinate). However, these did not correlate with subjectively assessed symptoms (Nasal Obstruction Symptoms Evaluation, all cross-sectional areas, P .05, except right middle turbinate; Sino-Nasal Outcome Test-20, all cross-sectional areas, P .05) or olfactory dysfunction evaluated with the Connecticut Chemosensory Clinical Research Center test (all cross-sectional areas, P .05) or the Cross-Cultural Smell Identification Test (all cross-sectional areas, P .05). Conclusion Endoscopic endonasal transsphenoidal approach surgery altered the patients' nasal anatomy, but the changes in nasal cavity dimensions did not affect nasal functions and symptoms. These results will help surgeons to appropriately expose the surgical field during endoscopic endonasal transsphenoidal approach surgery.</P>
