Purpose: To evaluate the efficacy and safety of laparoscopic renal cryoablation (LRC) of small endophytic renal cell carcinoma, for which surgical treatment is technically difficult. Materials and Methods: We enrolled patients with endophytic tumors from a prospectively collected database of 45 renal tumors in 39 patients who had undergone LRC from June 2005 to May 2009. An endophytic tumor was defined as less than 40% of the lesion extending off the surface of the kidney. We evaluated surgical and oncological outcomes. Results: Among the treated tumors, 17 tumors (37.8%) were defined as endophytic tumors and 15 tumors from 14 patients were confirmed as renal cell carcinoma (RCC) in the pathologic examination of the tissue biopsy that was conducted at the time of LRC. The mean American Society of Anesthesiologists (ASA) score of the whole patient group was 2.9 (range, 1-4), and 85.7% (12/14) of the patients had an ASA physical status score over 3. The mean tumor size was 2.8 cm (range, 1.7-3.7 cm). The layout of the cryoprobe was carefully planned preoperatively on the basis of radiologic evaluation in all tumors. Multiple cryoprobes (mean, 3.2; range, 2-5) were used. No major complications, including open surgical conversion and nephrectomy due to bleeding, occurred. No patient experienced clinical symptoms of collecting system injuries. During the mean follow-up of 32.6 months (range, 12-51 months), radiologic evidence of tumor recurrence was found in one patient (6.7% for RCC). With the exception of this patient, all other patients have remained free of recurrence or metastasis, as determined by periodic radiologic workups. Conclusions: In this series of patients with intermediate-term follow-up, LRC for endophytic renal cell carcinoma showed acceptable oncological and surgical outcomes without sequelae in the collecting system.

The biodegradation charcteristics of phenol by Pseudomonas putida KCTC 1643 was studied in a bubble column bioreactor as batch fed-batch and continuous operation. Phenol could be utilized as the sole carbon source by P. putida, however, the degradation level for phenol was increased from 58.2% to 99% because of cell growth by glucose addition to basal media. The growth rate of P. putida decreased with phenol. At initial phenol concentration of 0.6g/L, degradation rate had its maximum value. In the continuous operation the maintenance of cellular stability from Phenol inhibition was a important parameter for the degradation of Phenol.

Ⅰ. 서 론기업경영의 성패를 좌우하는 여러 가지 요인들 중 가장 중요한 것은 조직구성원들의 공. 즉 조직구성원들이 조직에 대해 얼마나 큰 관심을 가지고 열심히 공헌할 의욕이 있는가 하는 조직몰입수준이 기업경영의 성공의 중요한 요인 중 하나라고 할 수 있다.구성원들의 조직몰입에 영향을 미치는 요인들은 조직의 리더십 형태 , 과업의 성공 가능성, , 조직의 환경, 구성원의 개인적 특성 등이 있다 . 본 연구에서는 이들 변수들의 상호관계를 실증적으로 분석하여 규명하고 , 조직구성원의 조직몰입도와 임금의 공정성에 영향을 미치는 요인들 특히 조직의 리더십 성향 , 인사평가의 공정

esus focused most of His ministry on the proclamation of the Word and His ministry of healing. Jesus' healing work was not defective in the slightest, and He healed the whole person perfectly. However, today's human medical practice, although it provides services for a fee, is not perfect, leading to dissatisfaction among medical consumers. In this study, in order to find out the influence of factors affecting the quality level of medical services in Korea that affect the satisfaction of medical consumers, we tried to test the difference between patients' expectations and perceived experiences of medical services using a SERVQUAL model. Regarding these quality levels and factors, we decided to find out whether there are differences according to gender, age, size of medical institutions, and type of treatment, and hypotheses were established and tested. The sample distributed questionnaires to 400 randomly selected people among office workers, and 197 cases recovered were a valid sample. The survey period is from April 1 to November 19, 2022. The statistical package used to analyze the questionnaire is IBM-SPSS. v.26. As a result of the empirical analysis, the factors affecting the quality of medical services appeared in the order of reactivity-empathy-fluidity-guarantee-reliability, and it was confirmed that reactivity was the most important factor and reliability was the least influential. This can be seen as a general of factors rather than any one particular factor that determines the quality of medical services. On the other hand, in tests of demographic variables for the quality of medical services or differences according to the size of hospitals and the type of care, some factors were adopted and some factors were rejected. 예수님은 공생애의 대부분을 말씀선포와 치유사역에 집중하셨다. 예수님의 치유사역에는 조금도 결함이 없으시고 완벽하게 전인치유를 하셨다. 그러나 오늘날 인간의 의료행위는 대가를 받고 서비스를 시행하지만 완벽하지 못하여 의료소비자들의 불만족을 초래하고 있다. 본 연구에서는 의료소비자들의 만족에 영향을 주는 우리나라 의료서비스의 품질의 수준에 미치는 요인들의 영향력을 알아보기 위하여 서브퀄 모델을 이용하여 의료서비스에 대한 환자들의 기대와 인지된 경험 간의 차이를 검정하여 알아보고자 하였다. 그리고 이러한 품질 수준과 요인에 대하여 성별, 나이, 의료기관의 규모, 진료유형에 따른 차이가 있는 지도 알아보기로 하고 가설을 설정하고 검정 하였다. 표본은 직장인을 대상으로 임의로 선정된 400명을 대상으로 설문지를 배포하여 회수된 197건을 유효한 표본으로 하였다. 설문조사기간은 2022년 4월 1일부터 11월 19일까지이다. 설문지 분석을 위하여 사용된 통계 패키지는 IBM-SPSS. v.26이다. 실증분석의 결과 의료서비스 품질에 미치는 요인은 공감성-반응성-유형성-신뢰성-보장성의 순으로 나타나서 공감성이 가장 중요한 요인이고, 보장성은 영향력이 가장 낮은 것으로 확인되었다. 이것은 의료서비스의 품질을 결정하는 요인이 어느 특정한 하나의 요인이라기보다는 요인들의 전반적인 것들이라고 볼 수 있다. 한편 의료서비스 품질에 대한 인구 통계적 변수나 병원의 규모 및 진료의 종류에 따른 차이 검정에서는 일부 요인은 채택되고 일부 요인은 기각되었다.
