Currently, Stream flow analysis has been accomplished by one or two dimensional equations and was applied by simple momentum equations and fixed energy conservations which contain many reach uppermost limit. In this study, FLOW-3D using CFD(Computational Fluid Dynamics) was applied to stream flow analysis which can solve three dimensional RANS(Reynolds Averaged Navier-Stokes Equation) control equation to find out physical behavior and the effect of hydraulic structures. Numerical simulation accomplished those results was compared by using turbulence models such as $k-\varepsilon$, RNG(Renomalized Group Theory) $k-\varepsilon$ and LES(Large Eddy Simulation). Numerical analysis results have been illustrated by the turbulence energy effects, velocity of flow, water level pressure and eddy flows around the side overflow type structures at Jangwall bridge in urban stream.

The fast development of vaccines against the novel coronavirus disease is among the most critical steps taken to control this potentially fatal viral disease. Like other vaccines, the coronavirus disease 2019 (COVID-19) vaccines can also cause unwanted reactions. Erythema multiforme (EM) is among the oral mucocutaneous side effects of COVID-19 vaccines. This study aimed to comprehensively review the reported cases of EM since the global onset of COVID-19 vaccination. Data from 31 relevant studies regarding the type and dose of COVID-19 vaccines administered, time of initiation of symptoms, age, and gender of patients, site of involvement, patients' medical history, and treatment options were extracted. In total, 90 patients were identified with EM as a side effect of COVID-19 vaccination across studies. EM had the highest frequency after receiving the first dose of mRNA vaccines in older individuals. The first symptoms of EM appeared in less than 3 days in 45% and after 3 days in 55% of patients. EM is not a common side effect of COVID-19 vaccination, and fear of its occurrence should not impede vaccination.

Background: This study aimed to assess the most common physical side effects experienced by local chemotherapy patients. Their perceptions of these side effects and informational needs from clinical pharmacists were also evaluated. Materials and Methods: This was a single-center, cross-sectional study. A face-to-face interview guided by a structured questionnaire with cancer patients admitted to receive repeated cycles of chemotherapy was conducted. Information collected included chemotherapy-related side effects after last chemotherapy experience, the most worrisome side effects, the side effects overlooked by healthcare professionals and the preferred method, amount and source of receiving related information. Results: Of 99 patients recruited, 90 participated in this survey (response rate: 90.9%). The majority were in the age range of 45-64 years (73.3%) and female (93.3%). Seventy-five (83.3%) and seventy-one (78.9%) experienced nausea and vomiting, respectively. Both symptoms were selected as two of the most worrisome side effects (16.7% vs. 33.3%). Other common and worrisome side effects were hair loss and loss of appetite. Symptoms caused by peripheral neuropathies were perceived as the major symptoms being overlooked (6.7%). Most patients demanded information about side effects (60.0%) and they would like to receive as much information as possible (86.7%). Oral conversation (83.3%) remained as the preferred method and the clinical pharmacist was preferred by 46.7% of patients as the educator in this aspect. Conclusions: The high prevalence of chemotherapy-related side effects among local patients is of concern. Findings of their perceptions and informational needs may serve as a valuable guide for clinical pharmacists to help in side effect management in Malaysia.

The auther studied clinically and. radiologically 48 cases which had been diagnosed as TMJ ankylosis in SNUDH (1974-1984). The purpose of this study is to analyse clinical features of TMJ ankylosis and to evaluate the effect of TMJ ankylosis on the growth of the mandible. The obtained results were as follows: 1. Total 48 cases of TMJ ankylosis patients consist of 23 males and 25 females. 65 percent of all cases of TMJ ankylosis occurred in patients between 1 and 10 years of age. The awerage age at the onset of ankylosis was 11.7 and average duration at the time of examination was 11.7 years. 2. Unilateral akylosis (81.3%) was more frequent than bilateral ankylosis (18.7%). 3. Traum a (57.9%) and infection (21.2%) were main etiology. 4. Inability to open the mouth (78.3%) and facial asymmetry (17.4%) were main chief complaints. 5. Mandibular morphology through radiographic features. (a) In TMJ ankylosis patients the ramus length of the ankylosed side was shorter than that of the non-ankylosed side. Comparing with the centrol group, ramus length of the each side was shorter than normal value. (b) The partial body length of the ankylosed side was longer than that of the non-ankylosed side. Comparing with the control group, partial body length of the each side was longer than normal value. Partial body length was related with antegonial notch depth. (c) Ratio of upper and lower ramus length at the level of mandibular foramen was smaller in ankylosed side than in non-ankylosed side. (d) Antegonial notch depth and ramus posterior contour depth were deeper in ankylosed side than in non-ankylosed side and those of both sides were deeper than normal value. (e) Gonial angle in ankylosed side was larger than in non-ankylosed side and that in both sides was smaller than normal value.

In summer, the natural ventilation performance for varying greenhouse width is very important in the glasshouses for year round cultivation. The effect of the side openings and greenhouse width on natural ventilation performance was analyzed by simulation. The necessary ventilation rate with different solar radiation transmittance increased significantly when the outside temperature grows higher. The necessary ventilation rate of 40% transmittance was about half of that of 90% transmittance. In consequence, shading effect on temperature control in greenhouse is significant in summer. When the total area of the openings for ventilation is constant, the maximum ventilation rate happens when the area of roof openings is equal to the area of side openings. This maximum ventilation rate is about 3 times of that of the greenhouse with roof openings and without side openings. Therefore, the side openings are advantageous to improve the natural ventilation in greenhouses. As the greenhouse width increases, the influence of side openings on the ventilation rate is becoming smaller. If the natural ventilation rate of the greenhouse with roof and side openings is to become double of that of the roof openings only, the width should be narrower than 38.4m for the Venlo type and 64m for Wide span type.

Side-jets enable the immediate maneuver of a missile compared to control surfaces; however, they may cause adverse effects on aerodynamic coefficients, for they interfere with freestream. To find out the impact of side-jets on aerodynamic coefficients, we simulate side-jets as air gas and utilize multi-fidelity models to evaluate differences between aerodynamic coefficients obtained with and without side-jets. We computed differences in aerodynamic coefficients to investigate side-jet effects for the changes of a Mach number, a bank angle, and an angle of attack. As a result, asymmetrically developed side-jets affect the longitudinal force and moment coefficients, and the lateral force and moment coefficients drastically change in-between -30 and 30 degrees of bank angles. In contrast, side-jets hardly influence the axial force coefficients. As for the axial moment coefficient, we could not determine the side-jet effect due to a lack of aerodynamic coefficient samples in the Mach number. All in all, we confirm that side-jets lead to the change of a missile attitude as they considerably vary the longitudinal and lateral aerodynamic coefficients.

Purpose: The purpose of this study was to explore the effects of Patient Controlled Analgesia (PCA) on the postoperative patient's pain management and recovery of bowel movement with gastrointestinal cancer Method: The participants were 249 patients diagnosed with gastrointestinal disease and scheduled for elective surgery, who were recruited to either the postoperative patient-controlled analgesia group or epidural analgesia group. Participants aged 20 and above were recruited from P, K, D, and I university hospitals in B city. Pain visual analogue scale, and recovery of bowel movement according to PCA-related characteristics were measured using structured questionnaires from April 2005 through December 2005. Descriptive statistics t-test and F-test were used to analyze the data. SPSS WIN 10.0 program was used. Results: Mean score for pain was 62.31. Scores for pain on the visual analogue scale were significantly lower in the epidural-PCA than in the intravenous PCA, and also significantly lower in the absence of side effect of PCA than in the presence of side effect. Recovery time for bowel movement was significantly faster in the absence of side effect of PCA than in the presence of side effect. Conclusion: Based on the findings, there is a significant difference in pain and no difference in first passage of flatus according to PCA infusion route in patients who are post-operative for gastrointestinal cancer.

The most common and unacknowleged something in the secondary parkinsonism is parkinsonism caused by drug abuse. Patient had a glossal tremor caused by a side effect of GIT regulators and antispasmodics taked for the purpose of cured cholecystitis. We thought that the cause of a glossal tremor is 'Pungdam(風痰)' and gave 'Chukdamtang(滌痰湯)'. As a result this patient was taken a quick turn for the better. This case is specific. Because parkinsonism is caused by GIT regulators and antispasmodics, and the symptom of side effect is a glossal tremor. We hope that this case arouse people's attention to a tremor caused by a side effect of drugs and is useful to medical cure and prognosis.

This study was done to investigate the changes in the quality of life(QOL) of patients who received radiation therapy after surgery for breast cancer. For this purpose, 35 patients were interviewed using a questionnaire. They were followed over 8 month period from the beginning of radiation therapy. Changes in the QOL, side effect of the RT(radiation therapy), depression were measured. The results can be summarized as follows : 1. The mean score of the side effect of RT increased significantly over the period of RT. When the RT was completed, the QOL score was the low-est, and the depression score was the highest, but the changes of these scores were not statistically significant. 2. When the 6-week RT was finished, the QOL was significantly correlated with QOL of the beginning of RT, depression at RT completion and age. At three months after the completion of RT, the QOL was significantly correlated with QOL of the beginning of RT, depression and side effect of RT at three months after the completion of RT. At six months after the completion of RT, the QOL was significantly negatively correlated with age. 3. In the stepwise multiple regression analysis, the major influencing variables on the QOL were various according to the time lapse after the RT. The QOL at the completion of RT was predicted by the QOL at the beginning of RT, depression at the completion of RT and age. The QOL at three months after the completion of RT was predicted by the QOL at the beginning of RT and side effect of RT and depression at three months after the completion of RT. The QOL at six months after the completion of RT was predicted by age. This study suggests that continuous nursing care be required for improving the QOL of breast cancer patients not only during the RT period but also for a long term after the completion of RT.
