Thoracic surgery may be greatly facilitated by causing selective atelectasis of the lung being operated on (one-lung ventilation anesthesia). But the tube used for one-lung ventilation is greater outer diameter than conventional endotracheal tube when compare to each other with same inner diameter, so in some young children it is impossible to one-lung ventilation using double lumen tube or bronchial blocker tube because of narrow vocal cord. We performed one lung ventilation anesthesia using conventional endotracheal tube and Fogarty catheter as a bronchial blocker in 11-year old women who received lung biopsy surgery and left lower lobectomy.

Objectives: To demonstrate a number of advantages of Gd-enhanced MR-venography with FISP techinuque in diagnosis of extremity deep vein thrombosis. Method and Materials: Gd-enhanced MR venography with FISP technique was performed in patients had deep venous thrombosis of lower limb. Findngs of MR venography was retrogradely analyzed. Results : Gd-enhanced MR-venography clearly demonstrates venous anatomy of the lower extremities in all cases. And, deep vein thrombosis was well detected with signal void filling defect. MR-venography also shows additional combined findings in deep vein thrombosis. Conclusion : Gd-enhanced MR venography well demonstrates the anatomy of lower extremities and is a useful method for detection of deep vein thrombosis.

It is a relatively rare clinical experience to see the impacted first molar. The first permanent molar is the dey in normal occlusion. Abnormal eruption of the first permanent molars would inflict normal development of dental arches and give rise to abnormal root resorption of the adjacent teeth. Therefore, the abnormally erupted first permanent molars should be detected and treated early in order to obtain proper occlusal guidance in mixed dentition period. This report presents two cases on distally tilted and impacted mandibular first molars which were treated by surgical exposure and orthodontic traction using facial mask.

Background and Objectives: Evidence based practice is a hallmark of professional nursing. However, low levels of research utilization are problematic in nursing. The purposes of this study were to identify the facilitators and barriers to research utilization and to identify factors associated with research utilization among nurses. Methods: A descriptive study was conducted with a sample of 227 nurses in a university hospital located in a metropolitan city. The questionnaire included the Barriers Scale and questions about research activities, research related educational needs, and resources used to obtain information for clinical decision making. Results: The main barriers to research utilization identified by the respondents were: the fact that most research is published in a foreign language; implications for practice are not made clear; the research has not been replicated. The greatest mean score of each of the sub-scales was the communication factor followed by the organization, research, and nurse factors. Nurses who had received education for research methods, statistics, and reference search and who had participated research activities reported lower barrier score than those who did not. Conclusions: Although the nurses perceived the importance of research utilization in their practice, there was a poor application in their work. Decreasing known barriers would facilitate research-based practice. The implications for nursing to decrease the barriers to research utilization are discussed.

In order to develop a dandelion (Taraxacum officinale) with natural food applications, the effects of dandelion leaves and roots powder content on the physical, textural and sensory properties of sulggidduk were examined. Dandelion powders of leaves and roots at 0, 1, 2 and 3% were added to the dandelion sulgidduk. In the dandelion roots powder in sulgidduk, the color intensity of L values and the values and moisture content decreased however, the sensory color intensity, dandelion flavor and overall acceptability increased with increasing the dandelion powder content. The sensory overall acceptability indicated the dandelion roots powder content at 3% had the highest overall and flavor scores. As the dandelion leaves content was increased, the moisture contents, lightness, adhesiveness and cohesiveness of sulggidduk decreased, while the sensory color intensity, sensory hardness, hardness of texture properties and dandelion flavor increased. The addition at 1% of the dandelion leaves powder content with the dandelion sulggidduk and the addition at 3% of the dandelion roots powder content with the dandelion sulggidduk showed the highest overall acceptability.

Two methods, the bin averaging method and least square method, are often used in calibrating wind turbine test sites. The objective of this work was to determine a better method to predict the wind speed at wind turbine installing point. The calibration was done at the test site on a complex terrain located in Daegwallyeong, Korea. It was performed for two different cases based on the IEC 61400-12 power performance measurement standard. The wind speeds averaged for 10 minutes ranged between 4 m/s and 16 m/s. The wind-direction bins of each meteorological mast were 10 degrees apart, and only the bins having data measured for more than 24 hours were employed for the test site calibration. For both cases, the two methods were found to yield almost same results which estimated real wind speed very closely.
