The purpose of this study was to investigate the effects of gender, science achievement, perceptions of science, and out-of-school experience on middle school students' science career aspiration. We conduced a survey on 181 middle school students and investigated whether there was a difference in perception of science and out-of-school experience according to science career aspiration, and derived the eight variables from survey items based on exploratory factor analysis. And we conducted a logistic regression analysis that explains the effects of eight derived variables, gender, and science achievement on science career aspiration. The result of analysis showed that only two factors such as 'interest and preference for science learning' and 'use of everyday tools' were significant to explain science career aspiration. It has thus been found that it is important to increase students' interest in and preferences for science learning and use of tools in everyday life in order to increase their science career aspiration.

The purpose of this study was to measure the job aspiration and examine the relationship between that and job satisfaction for wage-earners using the fourth Korean Working Conditions Survey(KWCS). We use the stochastic frontier model for measuring the job aspiration and testing its effect on the job satisfaction. Fstochastic frontier model is introduced to explain that each company potentially produces less than it might due to a degree of job aspiration, measured by decomposing the residuals. In this model framework, it can be regard that the upper bound of the job satisfaction is the ideal frontier, and the bias between the ideal condition and the reality is the job aspiration. If this concept is applicable to the job aspiration, we can measure this bias and investigate a relationship with the job satisfaction. We find that there exists the job aspiration, and it is significantly negatively correlated with the job satisfaction. This result supports that if job aspiration increases, job satisfaction level decreases.

This study was undertaken to access the effect of collection methods on the collection efficiency, blastocyst rate and pregnancy rate after IVP embryo transfer. The ovaries of Hanwoo were obtained from an abattoir and kept on 25 to $28^{\circ}C$ and transported to laboratory within 4 hrs. The oocytes were collected by aspiration of follicles $(2\~6\;mm)$ with or without slicing of ovaries after aspiration. The oocytes were matured in vitro (IVM) for 20 to 24 hrs in TCM-199 supplemented with $10\%$ fetal bovine serum at $39^{\circ}C$ under $5\%\;CO_{2}$ in air. Following routine IVM/IVF procedure, the oocytes and presumed zygotes were cultured for three day in CRlaa medium with BSA. The cumulus cells at 2 to 8-cell stage of embryos removed then the embryos and were cultured in CRlaa medium containing $10\%$ fetal bovine serum in $5\%\;CO_{2}$ at $39^{\circ}C$. The fresh blastocysts cultured for 7 to 9 days were transferred into recipients. The numbers of oocytes recovered form two different methods, the aspiration and slicing after aspiration, were compared to know what. The number of oocytes per ovary was 8.2 and 6.5 in aspiration combining slicing, and aspiration groups, respectively (p<0.05). The cleavage rate in aspiration method are significantly (p<0.05) high than those in slicing post aspiration $(27.9\%)$, and aspiration $(25.5\%)$. The pregnancy .ate in aspiration method $(62.5\%)$ was high than that in slicing method after aspiration $(54.4\%)$. The pregnancy rates of aspiration method and slicing method after aspiration in nullipara $(58.1\%\;vs\;68.2\%)$ was high than that in pluripara $(49.5\%\;vs\;53.2\%)$. The results obtained that the increased number of oocytes per ovary in slicing method after aspiration could be better than that in aspiration method. Pregnancy rate in aspiration method was slightly higher in than that in slicing method after aspiration.

Pancreatic pseudocyst is one of the most common pancreatic mass lesions developed following acute or chronic pancreatitis. Two dogs were presented with nonspecific clinical signs such as abdominal pain, vomiting and depression and diagnosed as pancreatic pseudocysts through percutaneous ultrasound-guided aspiration. Pancreatic pseudocyst may contain pancreatic juice, so leads the deteriorate state of patient through pertinent inflammation and autodigestion of pancreas. In this study, the clinical signs and pancreatic lesion were improved after aspiration. Percutaneous ultrasound-guided aspiration can provide the diagnostic information through cytology and lipase and amylase concentration, and be selected as the first choice for treatment.

Holstein cow ovaries obtained at a slaughterhouse were used to study the influence of the oocyte collection methods (slicing, puncture, aspiration I and II) on recovery efficiency and subsequent in vitro maturation and embryonic development competence of immature oocytes recovered. In the slicing method, the whole ovarian was chopped into small pieces with a surgical blade. In the puncture method, the whole ovarian surface was punctured by 18-g needle. In other 2 aspiration methods, collected oocytes by aspirating from the visible follicles using an 18-g needle attached to a 5 ml syringe (aspiration I) or using a constant negetive pressure (-80 mmHg) with a vacuum pump (aspiration II). The oocytes were classified into 4 classes on the basis of the morphology of cumulus cells and cytoplasmic appearance of oocyte. Slicing ($9.6{\pm}0.4$) and puncture ($9.7{\pm}0.4$)yielded a larger number of oocytes per ovary than other two aspiration methods (aspiration I and II were $5.8{\pm}0.3$and $5.6{\pm}0.4$, respectively) (p<0.05). The number of the highest quality oocytes (grade A) per ovary was significantly higher in slicing ($4.2{\pm}0.2$) and puncture ($4.6{\pm}0.1$) methods than in other methods (aspiration I and II were $1.2{\pm}0.2$ and $1.4{\pm}0.2$, respectively) (p<0.05). The rate of nuclear maturation of the highest and higher quality oocytes (grade A and grade B, respectively) was not affected by the oocytes collection methods. The oocytes collection methods also did not influence subsequent embryonic developmental competence after in vitro fertilization with M II stage oocytes. It is concluded that slicing and puncture methods of the ovaries can be used as an alternative techniques to aspiration by the syringe or vacuum pump.

Purpose: This study was performed to test the clinical usefulness of the glucose test strip method for early detection of pulmonary aspiration in tube fed patients. Method: The subjects for the study were 36 patients who were receiving enteral feedings and 39 patients who were not given enteral feedings. For the analysis, the tube fed patients were divided into two groups (clinically significant aspiration and no aspiration) according to criteria. Result: The mean glucose concentration of tracheal secretions from non enteral fed patients was 26.35mg/dl and were lower than those concentrations found in tube fed patients (32.75mg/dl). The mean glucose concentration of the aspiration group was 45.60mg/dl and the glucose concentration of the non aspiration group was 19.93mg/dl. The difference was statistically significant (t=2.163, p=.038). More subjects in the no aspiration group ($73\%$) than the aspiration group ($56\%$) had glucose concentrations below 20mg/dl. After deleting the cases that had samples containing blood, glucose concentrations of tracheal aspirates were lower in both groups. Conclusion: The glucose level of the aspiration group was significantly lower than the no aspiration group and more subjects in the aspiration group had a glucose level higher than 101mg/dl. Therefore, the glucose test of tracheal secretions in tube fed patients could be a desirable test for screening for tracheal aspiration. Especially the patient who is showing repeatedly high glucose levels should not be given feedings until reassessment is completed.

There are a lot of dental emergency situation. Especially on disabled or pediatric patient with negative behavior, accidental aspiration or ingestion of foreign body (ex: dental instrument) is one of the common accidents in dental procedure. Dentists and dental hygienists must have knowledge about the precaution and be ready to deal with foreign body aspiration during dental treatment, especially on the disabled. This is a case of an accident during the dental treatment of 14-year-old female patient with cerebral palsy. During scaling, prolonged retained primary tooth which had resorbed roots was fell into left bronchi. So we tried to remove the crown by endotracheal approach. Most ingested foreign bodies pass through the gastrointestinal tract spontaneously, but some of them need endoscopic or surgical removal. Moreover aspiration into broncho-trachea can be more serious events and must be treated as emergency situation.

Aims: To determine suitable food textures for videofluoroscopic study of swallowing (VFSS), in order to predict and prevent subsequent aspiration pneumonia in esophageal cancer patients with dysphagia after surgery. Materials and Methods: We evaluated 45 hospitalized esophageal cancer patients who underwent surgery between January 2012 and December 2013. The control group consisted of 43 patients treatmed from January 2010 until December 2011 and were not examined by VFSS. Test foods, which were presented in order of increasing thickness, included thin barium sulfate (Ba) liquid (3 or 10 ml), slightly thickened Ba liquid (3 or 10 ml), a spoonful of Ba jelly, and a spoonful of Ba puree. Results: Patients could most safely swallow puree, followed by jelly. The 3-mL samples of both the thin and thick liquids put patients at risk for aspiration pneumonia, with incidence rates of 13% and 11%, respectively. While 64.4% of patients could swallow all test foods and liquids safely, 35.6% were at risk for aspiration pneumonia when swallowing liquids. Even though >30% of patients were at risk, only 1 (2.2%) in the VFSS group developed aspiration pneumonia, which occurred at the time of admission. Following VFSS, no incidence of aspiration pneumonia was observed. However, aspiration pneumonia occurred in 4 (9.3%) control patients during hospitalization. Conclusions: Postoperative esophageal cancer patients were more likely to aspirate any kind of liquid than solid foods, such as jellies. VFSS is very useful in determining suitable food textures for postoperative esophageal cancer patients.

Lung cancer is a type of cancer with high mortality; its 5-year survival rate is at a low 14%. Related cytological tests include sputum, bronchial brushing, bronchial washing and fine needle aspiration cytology test etc. From the test specimens in which sputum, bronchial brushing, bronchial washing, and fine needle aspiration cytology were performed, the sensitivity, specificity and accuracy between cytology test and histology test. In the sputum test, sensitivity was 27.71% and specificity was 98.02%, and the bronchial brushing test showed sensitivity of 93.33% and a specificity of 91.3%. The bronchial washing test was a sensitivity of 53.7% and its specificity was 98.9%, and the fine needle aspiration cytology test showed sensitivity and specificity were 88.46% and 72.97%, respectively. In the specimens diagnosed as normal at the sputum test, malignant diagnosis was found in 21 specimens of bronchial brushing, 30 cases of bronchial washings and 37 cases of fine needle aspiration cytology specimens. In the specimens diagnosed as normal at the bronchial washing test, malignant diagnosis was found in 5 specimens of sputum, 7 specimens of bronchial brushin and 1 cases of fine needle aspiration cytology. One specimens found to be normal in fine needle aspiration cytology turned out to maligant in sputum test. The result of this research shows that, in diagnosis lung cancer, a test method of high sensitivity and specificity should be pursued. However, depending on the location and malignancy of the illness, diagnosis may not be obtained in some cases. Therefore, we conclude that the cytological tests performed for lung cancer testing such as sputum, bronchial brushing, bronchial washing, and fine needle aspiration cytology should be carried out in a mutually complementary manner.
