목적: 산전 초음파가 널리 이용되면서 태아기의 선천성 요로계의 이상이 발견되는 경우가 점차 증가하고 있다. 수신증의 대부분은 출생 후 1년 내에 자연스럽게 없어지는 생리적 수신증이지만 수술적 교정을 요하는 병적 수신증과의 감별이 쉽지 않다. 본 연구에서는 산전 수신증이 의심되는 환아에서 출생 후 수신증을 확진하여 산전 진단과의 연관성을 비교 분석하고, 산전 수신증의 원인과 자연경과를 이해하여 출생 후 수신증에 대한 대처에 도움을 주고자 본 연구를 시행하였다. 방법: 1994년 9월부터 2001년 8월까지 아주대학교 병원 산과에 등록되어 산전 초음파 검사상 태아 수신증이 의심되었던 환아 119명 중 출생후 실시한 신 초음파 검사에서 수신증이 확진된 91명(121 신단위)을 대상으로 수신증의 원인과 자연경과를 신 초음파 검사와 배설성 신주사 검사로 추적 관찰하였다. 결과: 산전 초음파 검사에서 수신증이 의심되었던 119명의 신생아 중 출생 후 수신증이 확진 되었던 환아는 91명으로 76%였다. 수신증의 원인으로 요관 신우 이행부 협착이 57례(47%)로 가장 많았으며 그 다음으로는 다낭성 이형성신이 12례(10%), 요관 방광 이행부 협착 5례(4%), 방광 요관 역류 5례(4%), 후부요도 판막 2례(2%)등의 눈이었으며 원인을 찾을 수 없었던 경우도 38례(31%)였다. 추적검사에서 47%가 수신증의 완전소식 혹은 호전소견을 보였으며 총 121개의 신 단위 중 10단위가 수술을 받았으며 진단에서 수술까지는 평균 7.2개원이 걸렸다. 결론: 산전 초음파로 발견된 수신증의 대부분은 출생후 수신증으로 확진되었으나 정상인 경우도 있었다. 산전 수신증의 원인으로 요관 신우 이행부 폐쇄가 가장 많았으며 대부분은 비폐색성 수신증이었고, 추적 검사에서 호전되는 경우가 많았다. 그러나 아직까지 신생아 수신증은 정확한 감별진단이 어렵기 때문에 신장기능의 보전을 위해서는 수신증의 정도에 따라 적절한 간격으로 지속적인 관찰을 하는 것이 필요할 것으로 사료된다. Purpose : The detection of hydronephrosis(HN) with antenatal ultrasonography was first reported in the 1970s. Prenatal HN is diagnosed with an incidence of 1:100 to 1:500 on antenatal screening. Recently, the purpose of antenatal screening has changed from simple detection to selection for specific diagnosis-based management. this study is to evaluate the usefulness of antenatal sonography for HN and to investigate the differential causes of HN and their clinical outcomes. Patients and methods : 11,783 live neonates with prenatal ultrasonographic examination at Ajou University School of Medicine, from Sep. 1994 to Aug. 2001 were analyzed. Results and conclusion : Hydronephrosis (>10 mm) was detected in 119 (1.0%) cases antenatally and among these, 91 were proved to have HN postnatally Males were three times more affected than females. Additional imaging studies revealed that ureteropelvic junction obstruction was the most common postnatal diagnosis (47%), followed by multicystic dysplastic kidney, vesicoureteral junction obstruction and vesicoureteral reflux. During 20 months' follow-up(3 to 72 months), 58(48%) renal units showed spontaneous resolution and surgical interventions were necessary in 10 (7.4%) of postnatally confirmed hydronephrotic renal units.

The purpose of this paper is to investigate the removal efficiency of fine dusts as the configuration condition of machinery and equipments in Clean Room and to analyze the flowing behaviors of fine dusts as the layout of Clean Room. The layout of the Clean Room was classified into side layout type, 2 center line type and center concentration type layout, and the flow rates used in this research were 0.22m/s, 0.44m/s and0.80m/s. Dust removal efficiency as layout change was decreased 37% for side layout type, 31% for 2 centerline type and 20% for center concentration type layout at the flow rate of 0.22m/s, compared with the state without machinery and equipments in Clean Room. The efficiency was decreased 42% for side layout type,22% for 2 center line type and 8% for center concentration type layout at the flow rate of 0.44m/s, and decreased 20% for side layout type, 18% for 2 center line type and 10% for center concentration type layout at the flow rate of 0.80m/s. According to the result of dust removal behavior, $0.3\mum$, $1\mum$and $3\mum$dust except for $5\mum$showed the higher change of the behavior in side layout type than in center concentration type layout due to the change of air flow. It was confirmed that removal behavior depends on the layout of machinery and equipments as the dust size decreases.

Purpose: To investigate the effects of cataract extraction in chronic angle-closure glaucoma (CACG) patients. Methods: Sixteen eyes from 14 patients with CACG underwent phacoemulsification with posterior chamber intraocular lens (PCL) implantation (group A), and 19 eyes from 17 patients with CACG underwent cataract surgery and additional trabeculectomy (combined surgery, group B) were evaluated for visual acuity, intraocular pressure (IOP), number of glaucoma medications and surgical complications. All patients had patent peripheral iridotomy holes before cataract surgery, and a minimum 6 month follow-up period was needed. Results: The mean postoperative follow-up period was 15.6 months in group A, and 21.7 months in group B. After surgery, the IOP was significantly reduced in both groups [from 16.1 mmHg to 13.8 mmHg in group A (P=0.013), and from 16.7 mmHg to 13.2 mmHg in group B (P=0.005)], but the amount of IOP reduction was not significantly different between the two groups (P=0.401). The relative decrease in the mean number of postoperative glaucoma medications was 0.9 in group A and 1.8 in group B, but these were not significantly different (P=0.060). Conclusions: Simple cataract surgery was effective in reducing IOP as much as combined surgery in CACG patients. These results affirm that phacoemusification with PCL implantation may be considered as the first treatment in cataract and CACG patients.

Purpose: The purpose of the study was to identify the relationship between low back pain and job stress in hospital nurses. Method: A descriptive correlation research design was employed. The participants were 355 nurses who worked in a general hospital in W city Kangwon-do and consented to participate in this study. The Visual Analog Scale and job stress scale were used in this study. Analysis included descriptive statistics, t-test, ANOVA, and partial correlation coefficients. Results: Experience of low back pain for nurse in the past was 86.5% and in the present was 67.5% for low back pain which measured an average of 4.4 points for the level of low back pain. The mean score for job stress was relatively low(M=47.2). Job demand, organization system, job instability and conflict in relationships contributed to high stress scores, instead inappropriate compensation, job culture, and job autonomy contributed to low stress. There was a significant relationship between low back pain and job stress. Conclusion: These results suggest that further research is needed to develop programs to prevention and management of low back pain for nurses.

Purpose: To report a case of cytomegalovirus (CMV) retinitis in a child who had been managed by immunosuppressive chemotherapy for acute lymphoblastic leukemia (ALL). Methods: An 8-year-old boy who had been managed by immunosuppressive chemotherapy for ALL was referred to the ophthalmologic clinic because of blurred vision in his right eye. Fundus examination showed hard exudates and white retinal leaion in the macular area of the right eye, white retinal lesion accompanied with retinal hemorrhage and exudates in the midperipheral retina of the left eye. Serologic tests demonstrated a positive response of CMV antibody IgG and a negative response of CMV antibody IgM. CMV was isolated upon the culture of bone marrow and peripheral blood. Immunosuppressive chemotherapy was discontinued and ganciclovir was administered. Results: Administration of ganciclovir led to clinical stabilization of the retinitis lesion that was accompanied by scarring. We were able to discontinue the administration of ganciclovir after the retinal lesions were resolved, and no recurrence of CMV retinitis was noted. Conclusions: Ganciclovir treatment was clinically effective in improving CMV retinitis in an immunocompromised child with ALL. In addition, the improved systemic immune function achieved by discontinuing immunosuppressive chemotherapy permitted discontinuation of anticytomegalovirus therapy.

Advanced Practice Nurses' Organization Commitment: Impact of Job Environment, Job Satisfaction, and Person-Organization Fit

김연희,Shin Soo Il,Kim, Hye-Kyung,Jun, Myunghee,Wreen Michael 한국간호과학회 2023 Asian Nursing Research Vol.17 No.2

Purpose: The demand for advanced practice nurses (APNs) has increased globally due to a shortage of physicians and an increased demand for high-quality healthcare. Research is needed on the enhancement of advanced practice nurses' organization commitment. Organization commitment (OC) directly impacts the retention of APNs. This study aims to identify the key factors affecting the OC of advanced practice nurses. Method: A cross-sectional survey was conducted at the largest hospital in South Korea. A total of 189 APNs answered survey questions. A partial least squares-structural equation modeling method was employed to analyze the survey responses. Results: A pay scale of APNs is positively associated with person-organization fit (POF). However, the effect of job location and computer self-efficacy on POF is not significant. Job satisfaction plays a salient direct role in supervision and POF. Job satisfaction is also a significant moderator in the relationship between supervision and POF. POF is significantly associated with both OC and supervision. Supervision has a positive effect on organization commitment. Conclusions: Pay scale, job satisfaction, supervision, and POF are significant factors affecting organization commitment. Establishing an intra-organization entity, such as APN steering committee, to ensure mutual consensus and transparent communication between administrators and APNs would enhance POF, the rating of supervision, and organization commitment.
