Sonographic detection of ureteral jets entering the urinary bladder is a well-known procedure. Color Doppler ultrasound was used to image the ureteral jets in 28 patients with unilateral ureteral calculi proved by intravenous urography. Three major findings of ureteral jets were obtained in the affected ureter with a stone: less frequency (26 patients), weak reflection (20 patients), and lower grade in length (27 patients) that were significantly different from the unaffected side in the same patient. No significant differences were found between the ureteral jets and the degree of hydronephrosis or the location of a stone. In conclusion, these results suggest that ureteral jets should be checked routinely during the procedure of color Doppler ultrasonogram in patients with possible unilateral ureteral obstruction. Color Doppler examination of ureteral jets may be a important adjunct in routine pelvic ultrasonogram especially in patients who have absolute or relative contraindications of intravenous urography.

We have studied the genetic differences among four isolates of Trichinella including a new strain of Trichinella spiralis (ISS 623) recently found from a human case who took a badger in Korea. Because they have a different host origin and came from geographically separated regions, we supposed the genetic pattern of the isolates might be different as had been previously reported. It was analysed by PCR-RFLP analysis of the rDNA repeat that can readily distinguish a species or strain from others. Isolated genomic DNA of each isolate of Trichinella larvae was amplified with ITS1 specific primers and digested with restriction endonucleases. The PCR product of ITS1 was confirmed using Southern blot analysis to be a 910 bp fragment. The restriction fragments of each isolate had variable patterns when it was digested with Rsa 1 only. According to the RFLP patterns, the estimated genetic divergence between each isolate was different. In conclusion, four isolates of Trichinella including a new strain of T. spiralis obtained from a Korean patient may have genetic differences in the ITS1 region and the Shanghai isolate was genetically more similar to the Japanese unknown isolate than others in the ITS1 region.

PURPOSE: The purpose of this study was to verify the validity and reliability of a 14-item Resilience Scale (RS-14) by applying it to Korean university students. METHODS: The original English version of the RS-14 was translated into Korean, and the Korean version of the RS-14 was confirmed with back-translation. This was a methodological study, and data were collected from 273 students. Principal components factor analysis and Pearson correlation coefficients were used to test validity; Cronbach's alpha coefficient was used to test reliability. RESULTS: Factor analysis of 14 items revealed 2 factors with a total variance of 55.43%. The new scale correlated significantly with self-esteem (.48, p<.001) and depression (-.44, p<.001). Cronbach's coefficient was .905. CONCLUSION: The results indicate good validity and reliability for the Korean version of the RS-14. Future studies will need to further test this scale by applying it to different study populations.

PURPOSE: The purpose of this study was to understand the meaning and nature of adaptation experiences among newly employed nurses in oncology ward. METHODS: The present study adopted a phenomenological method. The participants were 9 nurses employed for less than one year. Data were collected by using in-depth interviews. The question of this study was, "What are your experiences as a newly employed nurse in oncology?" RESULTS: 150 significant statements were extracted from the data, and these were clustered into 5 main categories: a 'Difficulty in performing the work of a cancer ward', 'problems with interpersonal relationships', 'striving to be a good nurse', 'satisfaction and rewarding nursing', and 'adapted oneself to be a nurse'. CONCLUSION: Newly employed nurses in oncology ward experienced and perceived feelings of difficulty in performing the work of a cancer ward, problems with interpersonal relationships, striving to be a good nurse, satisfaction and rewarding nursing, and adapting oneself to be a nurse. It is necessary to understand the experiences of new nurses, and to provide strategies that could help new nurses effectively adapt and find the meaning in their adaptation to work in oncology wards. Further research is needed on development of a program focusing on training to improve practicing ability and interpersonal relationships skills.

PURPOSE: This study was done to develop and test the effectiveness in late school-aged children of a healthy lifestyle education program for cancer prevention. METHODS: Participants were 26 students in the sixth grade of N elementary school in J City (experimental group) and 25 students in the sixth grade of D elementary school with same educational conditions (control group). The research design was a nonequivalent control group pretest-posttest design. Data collection and execution of the study were carried out from March 10 to May 19, 2011. For the experimental treatment, 7 weekly sessions of the healthy lifestyle education program for cancer prevention were given by the researcher. Posttest was done immediately following the conclusion of the program and 4 weeks later. Frequencies, percentages, chi2-test, t-test, repeated measures ANOVA and paired t-test with SPSS WIN 18.0 were used to analyze the data. RESULTS: Perceived barriers, perceived self-efficacy, activity related effect and family support significantly influenced cancer prevention knowledge and increases in healthy life styles. CONCLUSION: Results indicate that, as this program for cancer prevention was effective in increasing healthy lifestyle practices in these children, there is a need to further develop, test and implement programs in all schools.

PURPOSE: This study was done to identify the level and correlation of knowledge and practice of fever management at home and provide data for the development of an intervention program to improve the fever management ability of mothers of preschool age children. METHODS: Participants were 112 mothers with children between 1 and 6 years of age and attending one of three daycare centers located in J city. The participants had a history of using medication and tepid massage. Data were collected during April, 2016. RESULTS: The mean scores were 27.55 (correct answer rate 70.64%) of 39 for knowledge, and 75.93 of 92 for fever management practice. There were significant differences in scores for knowledge according to the number of children and number of visits to doctors for treatment of a fever. There were no differences in scores for practice. There was a positive correlation between knowledge and practice. CONCLUSION: Results indicate that mothers' knowledge and practice of childhood fever management were insufficient to provide accurate management of childhood fevers. Therefore, to improve the mothers' ability to provide appropriate fever management, educational strategies that focus on increasing knowledge need to be developed.

Paranasal sinus CT is known as the most effective imaging modality in the evaluation of inflammatory sinonasal diseases and can depict the distribution, causative lesions obstructing main drainge route, and associated findings. Recently, functional endoscopic sinus surgery has been widely used for the evaluation and treatment. Before operation, PNS CT has been routinely used to evaluate the paranasal sinuses and mucociliary drainage route. The authors analyzed the PNS CT findings of 3156 cases in 1578 patients with chronic sinusitis symptoms. Sinonasal inflammatory diseases were categorized into 5 patterns according to the obstruction sites. They were 1) infundibular (10%, 316/3156), 2) ostimeatal unit (41%, 1294/3156), 3) sphenoethmoidal recess (12%, 379/3156), 4) sinonasal polyposis (30%, 946/3156) , and 5) unclassifiable (6%, 190/3156) patterns. The main causes for infundibular obstruction in order of frequency were inflammatory mucosa, enlarged ethmoidal bulla and Haller's cell. With respect to the middle meatus obstruction, is main causes in the order of frequency were polypoid lesion, inflammatory mucosa and medially deviated uncinate process. In particular, sinonasal polyposis showed one or more of the characteristic associated findings of infundibular enlargement, air-fluid level, ethmoidal sinus was bulging and bony deossification or sclerosis as well as sinonasal polypoid change. In conclusion, the inflammatory sinonasal diseases were classified into five patterns, and the causative lesions or anatomic variations were efficiently detected by the PNS CT. Furthermore, it could provide a guidance for proper management of the sinusitis including functional endoscopic sinus surgery.

BACKGROUND: Although intracranial hemorrhage is a dreadful complication of thrombolytic therapy in acute ischemic stroke, increased densities on immediate CT after intraarterial thrombolytic therapy in some cases, does not have any clinical deterioration and improve dramatically on follow-up CT. This unusual observation inspired us to determine the nature of the lesion of increased density on immediate CT finding, after intraarterial thrombolytic therapy. SUBJECTS AND RESULTS: Eight patients presenting with acute middle cerebral artery or internal carotid artery territory strokes were treated by emergency intraarterial urokinase with superselective catheterization. Fight of them had the areas of increased density in the territory sustaining the ischemic event on the immediate CT, performed within 30 minutes after thrombolytic therapy. Most lesions resolved definitely on follow-up scan within 48 hours of their detection. No cases were associated with clinical deterioration. CONCLUSION: As those lesions were cleared so fast without any clinical deterioration, the area of increased density should not necessarily be interpreted as hemorrhage alone. The density change on immediate CT after intraarterial thrombolysis partially attributable to extravasated pure contrast materials.

Monitoring fetal movement serves as an indirect rneasure of fetal well-being, especially for central nervous system integrity and function. Methods to monitor fetal movement vary from the simple approach of having the mother chart perceived movement to highly specialized methods. However there were no reliable objective monitoring methods in Korea. For development of objective method for evaluating fetal movement, during pregnancy, one-hundred and two pregnant patients were entered to this study. All patients were divided into following 3 groups and each type of monitoring methods were applied. Group 1(N=20): Type I using portable FHR Doppler unit(IFD-100 model, Intermed, Korea). Group 2(N=20): Type II using FHR Microphone(Prenatal Listening Kit, Model FS002, Unisar Inc., US). Group 3(N=62): Type III using conventional ultrasound transducer(Corometric 115 Model, US). In this study, accurate counting of the fetal movementutus were best performed using Type III, because of monitoring fetal movements has its greatest efficiency when using conventional ultrasound transducer of fetal monitor. It was also attractive to doctors and nurses as a convenient methods because it needed only single transducer when compared to Type I and II. Although monitoring fetal body movement permits a general assessment of well-being, no perfect technique is still reliable. Futher techniques would be developed using the results of this study for improvement of several factors such as accuracy and objectiveness
