Purpose:
To investigate the flow characteristics using different thresholding methods on a choriocapillaris optical coherence tomography angiography (OCTA) image complemented with a structural En Face image.
Methods:
The 42 choriocapillaris OCTA images from healthy subjects were obtained with swept-source OCTA device and the 3 × 3-mm area OCTA images were processed with ImageJ. Using a raw choriocapillaris OCTA image and structural En Face image, we adjusted the different structural signal intensity. Then, the raw images and adjusted images were binarized with a global threshold and an auto local threshold using the Phansalkar method at 1- or 2-intercapillary distance. Then, the mean area, number, and size of the flow void, were compared among the images using different thresholding methods.
Results:
Mean flow void area, number, and size were different according to the different binarization method both in raw and adjusted images (all p < 0.001). The mean flow void area analyzed with global threshold method were well correlated with those with auto local threshold method both in raw and adjusted images (all intraclass correlations, >0.929).
Conclusions
Flow void features varied according to the different binarization methods but showed good correlation. The flow void characteristics according to the different binarization methods should be considered for the analysis of the choriocapillaris OCTA images complemented with a structural En Face image.

It is well known that proper gender assignment and treatment to a neonate born with ambiguous genitalia are extremely important. We reviewed seven patients with ambiguous genitalia who were surgically managed at our department during recent 5 years. The median age was 12.1 years (from 3 to 24 years) and patients consist of three female pseudohermaphroditism (adrenogenital syndrome), one true hermaphroditism, one male pseudohermaphroditism and two mixed gonadal dysgenesis. Three patients were managed with clitoral recession and vaginoplasty, each of them with clitoral recession vaginoplasty and gonadectomy, with clitoral recession and gonadectomy, with clitoral recession, with gonadectomy and bilateral mastectomy. One patient with adrenogenital syndrome was raised as male, but re-assigned and surgically corrected as female at her age of 16 years. Another one patient with true hermaphroditism was raised as male who underwent excision of female internal genitalia, gonadectomy and bilateral mastectomy in considering of patient's gender identity, appearance of external genitalia and parent's proposal although the karyotype was 46 XX. We suggest that gender assignment and surgical correction must be done as early as possible after full evaluation of fertility feasibility, karyotype, sex ability and patient and parent's proposal.

5.A Study on Obese Female College Students' Weight Control Experiences.
Korean Journal of Women Health Nursing 2004;10(4):291-300
PURPOSE: This study attempted to show the implications of obese female college students' weight control experiences and to use this as primary data for developing a nursing intervention. METHOD: The participants were 7 obese students who had tried losing weight at C College on Jeju Island. Their average age was 22 and BMI was 25.6kg/m (2) on average. The data were collected from May 17th to July 6th 2004, and in-depth interviews were conducted with open-ended questions. RESULT: The analysis was conducted by Colaizzi's phenomenological method, and the analyzed results were categorized into 9 criteria, 22 theme clusters and 50 themes. The 9 criteria include withdrawal, desperation, self-restraint, relief, satisfaction, distraction, depression, regaining self-control and negligence of health. They tended to go through a weight gain loss cycle in a repetitive manner, and were faced with great physical and mental difficulties. In addition, they often went on a severely-strict diet without taking their health condition into consideration, which, in effect, causes various health problems. CONCLUSION: This study gives insights into the weight control experiences of obese female college students, and it shows developing more practical and effective nursing interventions are urgently needed.

Uterine prolapse with pregnancy is rare condition. The overall incidence is 1/10000- 15000 deliveries. The complications from uterine prolapse range from minor cervical ulceration and infection to fetal death or uterine rupture. The fetal mortality was as high as 22% mainly due to prematurity, respiratory infection. The management of this condition is focused on preventing late occurrence of prolapse during pregnancy and continued reduction. We present a case of uterine prolapse in pregnancy with a brief review of the literature.

Ten children were selected out of 21 cases diagnosed as ureteropelvic junction obstruction between March, 1989 and March, 1992. The children were evaluated quantitatively using the renal cortical labeling agent, 99m technetium dimercaptosuccinic acid (Tc-DMSA), before and following pyeloplasty. The preoperative residual renal function and the extent of functional recovery were investigated. The children ranged from 15 months to 13 years old (average 6.8 years) and consisted of 8 boys and 2 girls. The obstruction was on the left in 7 cases and the right in 3. Symptoms on admission included pain in 5 cases, abdominal mass in 3 cases, and fever and chill in 2. The subjects divided into two groups. The first group consisted of children who did not have complications or other coexisting diseases, while the second consisted of who had pyonephrosis or vesicoureteral reflux. All patients underwent dismembered pyeloplasty and the results were satisfactory in all. 1. The preoperative differential renal function by Tc-DMSA renal scintigraphy ranged from 0.5% to 46.0% (mean 19.1%) and increased to 3.5% to 46.9% (mean 28.8%) postoperatively. 2. In five of the seven cases with uncomplicated ureteropelvic junction obstruction, differential renal function increased more than 1096 following pyeloplasty. In the two other cases which showed preserved renal function of up to 4096 preoperatively, noticeable changes not observed. 3. In the three cases with complicated ureteropelvic junction obstruction, (two cases associated with pyonephrosis and one case with vesicoureteral reflux) only slight increased differential renal function. In conclusion, we suggest that severely obstructed kidneys in infants and children spare nephrectomy and encourage pyeloplasty, even in cases of non-visualization on excretory urography in hopes of improving relative renal function.

PURPOSE: The purpose of this study is to investigate the perception of nursing students' on-site clinical experience at intensive care unit(ICU), which will help on developing fundamental tool to enhance the effect of their clinical practice. METHOD: Van Manens hermeneutic-phenomenological method has been used to analyze the data. Participants consisted of 74 third-year nursing students who performed the clinical practice at an ICU in C university hospital. The students got the group interviews and kept the clinical diaries. Data was collected from series of group interviews and contents of the students clinical diaries. RESULT: Major concerns related to students clinical practice were found as follows: [being nervous about unfamiliar machines and situations], [being frustrated about the patients], [feeling of helplessness], [being stupefied from witnessing a death], [realizing the importance of health], [realizing individual patient's precious value through family's love], [realizing the importance of treating a patient as human being], [realizing the differences between theory and practice], [modelizing two aspects of nursing: professional and personal], [readiness to become a capable nurse]. CONCLUSION: We are able to obtain in-depth understandings about the nursing students lived experience of clinical practice at the ICU. Based upon this, there is a need to develop a better nursing intervention enhance the effectiveness of the nursing students clinical practice.

Korean Journal of Urology 1994;35(3):261-264
Between July 1988 and June 1993, nine patients with renal and perirenal abscess were treated using the percutaneous management. Percutaneous abscess drainage was done under ultra- sound guidance and local anesthesia. Among the nine patients, two patients were managed by percutaneous aspiration only and the other seven patients were managed by continuous drainage using the 8.3F pig-tail or 14F Malecot catheter. The catheters were placed in the abscess cavity during the period from 4 days to 19 days (average 8 days). On the abscess culture, the organisms were identified in 9 cases ( 100%) ; E.coli was in 4 cases, S. aureus was in 2 cases, Proteus, Enterobacter, unidentified gram negative bacilli in 1 case, respectively. After catheter removal, all patients have remained free of symptoms during followup from 2 months to 32 months (average 20 months). We suggest that proper antibiotic therapy combined with ultrasound guided percutaneous drainage of renal and perirenal abscess is a choice of reasonable, safe and effective management in selected patients.
