Objective : On the magnetic resonance image (MRI) of the infiltrating brain tumor, enhancement is usually higher in malignant tumor than in benign tumor, and tumor cells can invade into the peritumoral area without definite enhancement. In various pathological conditions, the blood brain barrier (BBB) becomes changed to pathological condition, allowing various materials extravasating into the interstitial space, and degree of enhancement is depend on the pathology. Authors performed dynamic MRI on enhancing and surrounding edematous area in order to evaluate the degrees of opening of BBB, to differentiate tumor from non-tumorous condition, and to determine its relationship with the recurrence of the tumor. Methods : Dynamic MRI was performed in 25 patients. Dynamic scans were done every 15 seconds after administration of Gd-DTPA on the enhancing and surrounding area for maximum 300 seconds, and the patterns of enhancement were ana lysed. The enhancement curve with initial steep increase followed by slow decrease was defined as "N pattern", those with initial steep increase followed by additional slow increase as "T pattern", and those with initial steep increase followed by plateau as "E pattern". Histopathological findings were compared with the dynamic scan. Results : The graphs taken from enhancing area showed "T pattern" regardless of pathology. In the surrounding area, "T pattern" was noticed in the malignant tumors, but "E pattern" or "N pattern" was noted in low-grade or benign tumors and non-tumorous condition. "T pattern" in the surrounding area was related to the malignant with tumor cell infiltration and recurrence. Conclusion : The results suggest that the malignant tumor infiltration changes the condition of BBB enough to extravasate the Gd-DTPA. Enhancement pattern in the surrounding edematous area may be a useful information to differentiate the malignant glioma with the low-grade and benign tumors or other non-tumorous conditions.

급속하게 변화하는 오늘날의 시장은 혁신적이고 새로운 마케팅 접근 방식을 요구한다. 관계 마케팅은 가장 혁신적인 마케팅 접근 방식의 하나이다. 관계 마케팅 개념의 중요한 특징은 경쟁 우위를 위해 고객 관계를 구축하고, 유지하고, 강화하는 것이다. 고객 정보는 조직내에서 관계 마케팅 활동에 대한 토대를 제공한다. 관계 마케팅은 데이터베이스 마케팅 시스템의 개발과 사용 없이는 불가능하다. 관계 마케팅을 통해 경쟁 우위를 달성하는 데 있어서 가장 큰 장애는 DB 마케팅 시스템의 개발이다. 따라서, 만약 마케터들이 관계 마케팅을 활용하기를 원한다면, 성공적인 DB 마케팅을 위해 필요한 특성들을 반드시 규명해야 한 것이다. 많은 연구에서 관계 마케팅을 통해 경쟁 우위를 획득하는데 있어서 가장 핵심적인 요소가 조직적 장벽이 사실이라는 결론을 얻었다. Fletcher, et al.은 관계 마케팅에서 조직적 변수들의 중요성을 발견했지만, 이 영역의 연구는 상당히 미개척 분야이다. 이에 본 연구는 조직 변수와 DB마케팅 성숙도간의 관계에 대한 실증적 증거를 제시하고자 한다.

배 경: 결핵성흉막염환자에서 흉수 내 아데노신 탈아민효소(ADA) 활성도와 CT에서 흉막의 조영증강 양상과의 연관성에 대해 알아보고자 하였다.방 법: 2002년 2월부터 2006년 10월까지 결핵성흉막염으로 진단되고 동시에 조영증강 CT를 시행한 44명을 후향적으로 분석하였다. 결핵성흉막염의 진단은 흉수 내 ADA활성도와 추적검사(24/44), 객담도말이나 배양(16/44), 흉막배양(3/44), 그리고 흉막조직검사(1/44)로 얻었다. 흉수 내 ADA활성도 값이 40-70 U/L인 환자는 I군(12명)으로, 71 U/L이상인 환자는 II군(32명)으로 분류하였다. CT에서 흉막의 조영증강 유무, 최대 흉막두께, 조영증강의 양상을 분석하였다. 흉막의 조영증강 양상은 미만성(diffuse)인지 국소성(focal)인지, 매끈(smooth)한지 불규칙(irregular)한지, 혹은 단절성(Interrupted)인지 연속적(continuous)인지로 나누어 분석하였다. I군과 II군 사이에 CT 소견의 차이가 있는지를 분석하였다. 통계적 방법은 T 검정, 카이제곱검정 그리고 비율의 검정을 사용하였다.결 과: 44명 모두 CT에서 흉막의 조영증강이 관찰되었다. I군과 II군의 흉막의 최대 두께는 각 $1.83{\pm}1.03mm$ (1-4 mm), $3.63{\pm}1.78mm$ (18 mm)이어서 유의한 차이가 있었다(p= 0.0002). 특히, I군의 흉막비후의 두께는 모든 예에서 4 mm 이하이었고, 5 mm 이상으로 흉막이 두꺼워진 경우는 II군에서만 31.3%(10/32) 있었다. I군은 미만성이고 단절성인 흉막비후(diffuse, interrupted pleural enhancement)를 보인 예가 91.7% (11/12), 미만성이고 연속적인 흉막비후를 보인 예가 8.3%(1/12)있었고, II군은 각각 62.5%(20/32), 37.5% (12/32) 있었다. I군보다 미만성이고 연속적인 흉막비후(diffuse and continuous pleural enhancement)를 보인 예가 II군에서 많았으나 통계적 유의성은 없었다(p=0.0748).

Rapid Prototyping(RP) techniques have unique characteristics according to their working principle: the stair-stepped surface of a part due to layer-by-layer stacking, low building speed, and additional post-processing to improve surface roughness. A new RP process, Variable Lamination Manufacturing by using expandable polystyrene foam(VLM-S), has been developed to overcome the unfavorable characteristics. The objective of this study is to investigate the thermal characteristics and skeleton size effects as the hotwire cuts EPS foam sheet in order to improve dimensional accuracy of the parts, which is produced by VLM-S. Empirical and analytical approaches are performed to find the relationship between cutting speed and heat input, and the relationship between maximum available cutting speed and heat input. In addition, empirical approaches are carried out to find the relationship between cutting error and skeleton size, and cutting deviation and skeleton size. Based on these results, the optimal hotwire cutting condition and available minimum skeleton size are derived. The outcomes of this study are reflecting in the enhancement of VLM-S input data generation S/W.

Purpose: This study aimed to determine the moderating effect of self-esteem on the perception of death and the meaning of life among hospital nurses. Methods: The participants were 167 nurses working in two tertiary general hospitals located in city B. Data were collected from September 8 to 21, 2022. SPSS/WIN 29.0 was used for analysis along with t-test, ANOVA, Pearson correlation coefficients, and hierarchical multiple regression. Results: The study showed that the meaning of life was significantly correlated with the perception of death (r=.34, p<.001) and self-esteem (r=.31, p<.001). Self-esteem significantly moderated the relationship between the perception of death and the meaning of life (F=16.00, p<.001). Conclusion: Self-esteem may moderate the relationship between the two factors. This means that nurses with higher self-esteem have a greater tendency for their perception of death to positively impact their meaning of life. Therefore, for hospital nurses to discover the meaning of life, it is necessary to develop and apply a self-esteem enhancement program specialized for each clinical career.
