It has been well established that the kidney is the main organ producing erythropoietin (E.S.F.). Erythropoietin activity was reported to be increased in cases of renal tumor. cyst, polycystic disease and hydronephrosis. To study erythropoietic activity in hydronephrosis and renal cell carcinoma, erythropoietin bioassay by DeGowin method were performed in 7cases of hydronephrosis and renal cell carcinoma. Erythropoietin activity is significantly increased in renal cell carcinoma but not significantly increasedin hydronephrosis.

PURPOSE: To identify the effects of workplace bullying of hospital nurses on the quality of nursing service and to investigate the moderating effects of professional self-concept in the relationship between workplace bullying and quality of nursing service. METHODS: The participants in this study were 280 nurses working in hospitals located in J Province. Data were collected from December 20, 2016, to January 20, 2017. A self-administered structured questionnaire was used. Data were analyzed using the SPSS/WIN 22.0 statistical program. RESULTS: Workplace bullying had significant negative correlations with professional self-concept and nursing service quality. There was a significant positive correlation between professional self-concept and nursing service quality. Professional self-concept was the only variable to show a moderating effect in the relationship between the outcome of workplace bullying and quality of nursing service (β=−.12, p=.023). CONCLUSION: The findings from this study suggest building a systematic strategy to prevent workplace bullying at the organizational-level, where it threatens quality of nursing service and developing programs to promote professional self-concept, which can control the negative effect of workplace bullying.

PURPOSE: The purpose of this study was to determine gender differences in effects of self-efficacy, exercise benefits and barriers, and demographic factors on the physical activity. METHODS: Seventy sedentary office workers, 35 male and 35 female, from a major airline company, completed a questionnaire from March 28 to April 5, 2012. Steps and body mass indices were measured using a CW-700/701 (Yamax) pedometer and Inbody 720 (Biospace), respectively. Data were analyzed using t-test, chi2-test, multiple linear regression, and simultaneous quantile regression. RESULTS: For male workers, exercise self-efficacy had a significant effect on physical activity, but only when respondents were at 10%(3,431 steps/day, p=.018) and 25%(4,652 steps/day, p=.044) of the physical activity distribution. For female workers, marital status was significantly related to physical activity, but only when respondents were at 10% (3,537 steps/day, p=.013) and 25%(3,862 steps/day, p=.014) of the physical activity distribution. CONCLUSION: Quantile regression highlights the heterogeneous effect of physical activity determinants among office workers. Therefore intervention strategies for increasing physical activity should be tailed to genders as well as physical activity levels.

Tibial nonunion is often associated with the soft tissue atrophy and the local circulatory disturbance, so it is important to minimize the soft tissue injury and maintain the stability at fracture site for bone union. We reviewed 29 cases of subcortical onlay bone grafts and plate fixations for the nonunion and delayed union of tibial shafts, from Jan. 1988 through Jan. 1994. The results were as follows. 1. Twenty-nine patients who had nonunion of the tibia underwent subcortical cancellous onlay bone graft and plating, and 28 fractures(96.6%) went on to union. 2. Subcortical elevation or shingling of cortical bone fragments of the tibial cortex, is advocated to provide sound biological condition in atrophic soft tissue envelope. 3. Narrow DCP encouraged early motion and reliably promoted obtaining anatomical alignment. So, in treatment of protracted tibial nonunion, especially in an area with deficient soft tissue or unyielding scar tissue, subcortical onlay bone graft and plate fixation is very useful method, result in good union and no skin problem.

Purpose: This study aimed to explore the current status of systematic review studies on patient-reported outcome measures (PROMS) published in Korean journals. Methods: Studies on the systematic review of PROMs, which applied the COnsensus-based Standards for selecting health Measurement Instruments (COSMIN) methodology. There were searched from the KoreaMed. The studies were evaluated based on the eight steps suggested by the COSMIN systematic review processes. Results: A total of eight systematic review studies were published in seven Korean journals. Patient-reported outcome measures (PROMS) measure for post-traumatic growth, social adjustment, physical impairment in post-intensive care syndrome, sleep quality, constipation, discharge readiness, post-traumatic stress disorder, and eHealth literacy. Conclusions No studies adhered to the steps of the COSMIN systematic review guidelines. Among the steps, the weakest points were searching strategies and evaluating measurement properties.
