Purpose: To compare the amoebicidal effects of nephrite containing contact lens (CL) storage cases with conventional CL storage cases. Methods: Acanthamoeba lugdunensis were inoculated onto 5% nephrite containing CL storage cases as well as conventional CL storage cases both with and without silicone hydrogel contact lenses (SHCLs). Then the amount of Acanthamoeba proliferation on CL storage cases and the number of adherent Acanthamoeba on SHCLs were determined and compared. The effects of multipurpose solution (MPS) with and without 1% or 5% nephrite solution on Acanthamoeba adhesion were analyzed. Results: Nephrite containing CL storage cases showed more inhibitory effects on Acanthamoeba proliferation (p = 0.02) and significantly reduced the number of adherent Acanthamoeba on SHCLs compared with conventional CL storage cases, regardless of SHCLs generation (p = 0.001, p = 0.001 and p < 0.001, respectively). The number of adherent Acanthamoeba on the first generation of SHCLs was significantly reduced by MPS with 1% and 5% nephrite solutions (p = 0.03 and p = 0.004, respectively), but the numbers for the second and third generation SHCLs were not. Conclusions: Nephrite could be used as a new additive component for CL storage cases and multipurpose solutions to improve the disinfection effects on Acanthamoeba.

This research is a study on the welfare satisfaction of radiological technologists in university hospital, and was conducted in order to analysis of welfare factors and improvements. The survey was conducted on radiological technologist of a university hospital in Gyeongnam from July 14th 2014 to August 14th 2014, and we analyzed 121 of the questionnaire, which was retrieved by distributing. As a result, we looked at the welfare level of satisfaction by welfare hospital factors, each of the satisfaction scores were living welfare supports($2.83{\pm}0.43$), financial supports($4.25{\pm}0.65$), housing supports($2.28{\pm}0.46$), educational supports($2.58{\pm}0.50$), health medical supports($3.02{\pm}0.56$), culture and leisure supports($2.79{\pm}0.45$), other welfare supports($2.70{\pm}0.48$) points. The level of satisfaction with the hospital welfare support factors of average score level it was analyzed. It is important that is providing effective hospital welfare through survey for hospital welfare needs and benchmarking of welfare system of general corporate.

Background: The purpose of this study was to compare and analyze the differences in charges and length of stay per case between spine specialty hospitals and non-specialty hospitals, and to identify the factors that influenced them. Methods: This study used claims data from the Health Insurance Review and Assessment Service, including inpatient visits from January 2021 to December 2022. The healthcare facility status data was used to identify the characteristics of study hospitals. Multilevel analysis was conducted to identify factors associated with the charges and Poisson regression analysis was conducted to analyze the length of stay between spine specialty hospitals and non-specialty hospitals. There were 32,015 cases of spine specialty hospitals and 17,555 cases of non-specialty hospitals. Results: For four of five common spinal surgeries, specialty hospitals shaped longer length of stay than those of non-specialty hospitals. Multilevel and Poisson regression analysis revealed that regardless of the type of surgery, higher age and higher Charlson comorbidity index scores were significantly associated with an increase in both the charges per case and length of stay (p<0.05). However, when hospitals were located in metropolitan areas, there was a significant decrease (p<0.05). Conclusion: This study found that specialty hospital had higher inpatient charges and loner length of stay contrary to the previous study results. Further studies will be needed to find which contribute to the differences.

Xanthogranulomatous inflammation is a rare inflammatory reaction, characterized by lipid-laden macrophages, known as xanthomas, in histopathologic examination. Aggressive xanthogranulomatous inflammation often manifests as local infiltration but does not affect distant organs unless combined with rare systemic diseases. We report a case of focal xanthogranulomatous pyelonephritis (XGP) associated with severe xanthogranulomatous cholecystitis. Focal XGP was suspected in radiologic examination that showed a cystic lesion with an infiltrative margin, which were surgically resected and confirmed in pathologic examination. To our knowledge, this is the first report of focal xanthogranulomatous pyelonephritis associated with xanthogranulomatous cholecystitis. Moreover, we found peripheral hypointensity around the cystic lesion in the T2-weighted image, probably reflecting hemorrhage and fibrosis of the xanthogranulomatous inflammation.

Purpose: This study was conducted to investigate the relationship of hardiness, job stress, and burnout in nurses, and to identify predictors of burnout. Method: Empirical data were collected from 154 staff nurses at one university hospital in Gwangju city. Self- reported questionnaires were composed of the Personal Views Survey(PVS), job stress scale, Tedium scale, and 7 items asking nurse's general characteristics. Data analysis was done with a SAS package. Result: In correlation analysis, hardiness, job stress, and nursing satisfaction had significant correlation with burnout. In stepwise multiple regression, 28.7% of the variance in burnout was accounted for by nursing satisfaction (19.9%), job stress (6.0%), and hardiness (2.8%). Among subscales of hardiness, only commitment was a significant predictor, so nursing satisfaction, job stress, and commitment explained 28.9% of variance in burnout. Conclusion: Based on the findings of this study, the development of program for nurses to increase nursing satisfaction is needed, and more studies to examine causal relationship between nursing satisfaction and burnout is also highly recommended.

10개월경의 그리폰 벤딘 수컷 강아지가 8개월경부터 점점 운동 실조 및 마비증상을 나타내어 머독대학 동물병원에 내원 하였다. 내원 했을 때 주변에 매우 민감한 반응과 경계를 늦추지 않았지만 호흡과 심박수 및 체온은 정상이었다. 일반 방사선 사진 및 척수조영사진(myelography)을 촬영하여 확인한 결과 환축추의 불안정에 따른 척수의 복측 압박을 확인할 수 있었다. 외과적 고정은 복측 접근을 통하여 2개의 키르크너 강선(Kirschner wire)과 자가골이식을 실시하였으며 8주동안 외부 고정을 하였다. 수술 후 5개월 동안 지켜본 결과 증상은 꾸준히 좋아졌으며 환축추 관절으 관절고정술(arthrodesis)은 완벽한 고정을 유지하고 있었다.

스멀스멀 아지랑이 피듯 나른한 오월, 몸이 피곤하고 의욕이 없는 증상은 누구나 한 번쯤 겪어 보았을 것이다. 일반적으로 과로에 의한 피로는 충분한 휴식과 영양을 공급해주면 회복된다. 그러나 휴식을 취해도 호전되지 않고 피로가 6개월 이상 지속된다면 '만성피로'로 의사의 진찰을 받아보아야 한다. 왜냐하면, 피로의 원인이 당뇨, 암, 갑상선질환, 고혈압, 우울증 등에 있을 수 있기 때문이다. 실제로 원인 모를 피곤함으로 병원을 찾은 환자 중 종종 당뇨 진단을 받기도 한다. 그러면 당뇨병환자는 왜 기력이 떨어지고 피곤해하는지 당뇨와 피로의 상관관계에 대해 알아보도록 하자.
