Purpose: The purpose of this descriptive study is to examine the correlation between nursing students’ perception of nurses and the level of their satisfaction with the major. Method: The survey was done with the total number of 192 nursing students from 10 different universities in S city selected by a convenience samplingmethod. In order to measure the perception of nurses, the measurement which was invented by Lee(1992) and revised by Jang(1998) was used. Also, the measurement designed by Shim, and modified by Kim(2007) was used for measuring of the students’ satisfaction in their major. The collected data was analyzed by SPSS 17.0. Results: 1.The most decisive factor of the conceptualization of the image of nurses for the nursing college students is their experience of meeting nurses as a patient. 2. Students reconsider the role of nurses by experiencing immediate relationships with nurses in field training. 3. Other factors of the survey such as the students’academic year, religion, the field training situation (individual experience, type of the hospital where they experienced the training, and a relationship with the nurse in charge of the training) or the existence of nurses among their family members do not affect the students’ satisfaction. 4. There is a positive correlation between the image of nurses of nursing college students and their satisfaction with the major(0.66). Conclusion: The positive image of nurses is directly related to the students’ satisfaction in the nursing major, which hugely affects on their academic achievements and decisions of career path. Therefore, there should be more efforts to increase the positive perception of nurses among nursing students.

Objective : The effectiveness of gamma knife radiosurgery (GKR) in the treatment of brain metastases is well established. The aim of this study was to evaluate the efficacy and safety of maximizing the radiation dose in GKR and the factors influencing tumor control in cases of small and medium-sized brain metastases from non-small cell lung cancer (NSCLC). Methods : We analyzed 230 metastatic brain tumors less than 5 mL in volume in 146 patients with NSCLC who underwent GKR. The patients had no previous radiation therapy for brain metastases. The pathologies of the tumors were adenocarcinoma (n=207), squamous cell carcinoma (n=18), and others (n=5). The radiation doses were classified as 18, 20, 22, and 24 Gy, and based on the tumor volume, the tumors were categorized as follows : small-sized (less than 1 mL) and medium-sized (1-3 and 3-5 mL). The progression-free survival (PFS) of the individual 230 tumors and 146 brain metastases was evaluated after GKR depending on the pathology, Eastern Cooperative Oncology Group (ECOG) performance score (PS), tumor volume, radiation dose, and anti-cancer regimens. The radiotoxicity after GKR was also evaluated. Results : After GKR, the restricted mean PFS of individual 230 tumors at 24 months was 15.6 months (14.0-17.1). In small-sized tumors, as the dose of radiation increased, the tumor control rates tended to increase (p=0.072). In medium-sized tumors, there was no statistically difference in PFS with an increase of radiation dose (p=0.783). On univariate analyses, a statistically significant increase in PFS was associated with adenocarcinomas (p=0.001), tumors with ECOG PS 0 (p=0.005), small-sized tumors (p=0.003), radiation dose of 24 Gy (p=0.014), synchronous lesions (p=0.002), and targeted therapy (p=0.004). On multivariate analyses, an improved PFS was seen with targeted therapy (hazard ratio, 0.356; 95% confidence interval, 0.150-0.842; p=0.019). After GKR, the restricted mean PFS of brain at 24 months was 9.8 months (8.5-11.1) in 146 patients, and the pattern of recurrence was mostly distant within the brain (66.4%). The small and medium-sized tumors treated with GKR showed radiotoxicitiy in five out of 230 tumors (2.2%), which were controlled with medical treatment. Conclusion : The small-sized tumors were effectively controlled without symptomatic radiation necrosis as the radiation dose was increased up to 24 Gy. The medium-sized tumors showed potential for symptomatic radiation necrosis without signifcant tumor control rate, when greater than 18 Gy. GKR combined targeted therapy improved the tumor control of GKR-treated tumors.
A Case of Myelodysplastic Syndrome with Clinical Manifestations of Recurrent Cellulitis

An 84-year-old male patient with recurrent cellulitis in the left submandibular area visited the outpatient clinic. He underwent debridement of the wound with administration of intravenous antibiotics. The defect was reconstructed using a split-thickness skin graft. After 2 months, the cellulitis recurred adjacent to the prior lesion in the submandibular area. The wound improved with intravenous antibiotics and conservative treatment. During the second hospitalization, the patient was evaluated for abnormal complete blood count, and was finally diagnosed with myelodysplastic syndromes. Recurrent cellulitis in this patient was not accompanied with any other symptoms; instead of being a simple uncontrolled infection it had a systemic origin. Physicians should consider the possibility of systemic causes for recurrent cellulitis, such as myelodysplastic syndromes, especially if laboratory results suggest pancytopenia.

Background/Aims: Myelodysplastic syndrome (MDS) is caused by genetic and epigenetic alteration of hematopoietic precursors and immune dysregulation. Approximately 20% of patients with MDS develop an autoimmune disease (AID). Here, we investigated whether particular genetic mutations are associated with AID in patients with MDS. Methods: Eighty-eight genetic mutations associated with myeloid malignancy were sequenced in 73 MDS patients. The association between these mutations and AID was then analyzed. Results: The median age of the 73 MDS patients was 70 years (interquartile range, 56 to 75), and 49 (67.1%) were male. AID was observed in 16 of 73 patients (21.9%). Mutations were detected in 57 (78.1%) patients. The percentage (68.8% vs. 80.7%, p = 0.32) and the mean number of mutations (1.8 ± 1.6 vs. 2.2 ± 1.8, p = 0.34) in MDSpatients with or without AID were similar. However, the ten-eleven translocation-2 (TET2) mutation rate was significantly higher in patients with AID than in those without (31.3% vs. 5.3%, respectively; p = 0.001). All TET2 mutations were variants of strong clinical significance. Conclusions: Mutation of TET2 in patients with MDS may be associated with increased risk of developing AID.

최근 들어 ASIC이나 소형 시스템에서 사용할 수 있는 더 빠르고 정확한 움직임 벡터 예측방법이 요구되고 있다. 블록 움직임 벡터를 예측하기 위한 전역탐색 (Full Search: FS) 방법은 탐색영역의 모든 화소들을 탐색하여 움직임 벡터를 예측하는 방법으로 화질과 PSNR은 좋지만 많은 계산량이 요구된다. 이전에 제안된 고속 알고리즘들은 탐색하는 회수를 제한함으로써 계산량을 줄였기 때문에 움직임 벡터 예측의 정확도가 낮고, 움직임 보상시 SAD 값이 높아지는 것을 감수해야한다. 본 논문은 기존의 고속 알고리즘과 유사한 화질을 유지하면서 속도를 향상시키는 저비트율에서 효과적인 새로운 움직임 예측 탐색 알고리즘을 제안한다. NSS (A New Past Subsampling-based Search Algorithm for Block Motion Estimation)라 불리는 제안된 알고리즘은 서브샘플링 방법을 위한 디더링 패턴과 주위 블록의 움직임벡터를 이용하는 방법을 기반으로 하고 있다. 제안된 알고리즘은 기존 알고리즘들과 유사한 시각적 화질을 제공하면서 입력 비디오 영상에 따라 약 50% 정도 계산량을 줄일 수 있다. Recently we needs a faster and more accurate motion vector search algorithm for an ASIC (Application Specific IC) or a small system. A full search algorithm for block motion estimation is computationally intensive even though it can provide the best visual quality. Previously proposed fast algorithm reduce the computation by limiting the number of searching locations. This is accomplished at the expense of less accuracy of motion estimation and gives rise to an appreciably higher sum of absolute difference (SAD) for motion compensated images. In this paper, we present a new fast search algorithm for block motion estimation that can produce proper visual quality Performance and less computational time compared with conventional fast algorithms. The proposed algorithm, NSS (A New Fast Subsampling-based Search Algorithm for Block Motion Estimation), is based on the ideas of dithering pattern for pixel decimation and using motion vectors in adjacent macro blocks. NSS is especially an efficient method for low bit-rate video coding. From the experimental results, the proposed algorithms is superior to conventional fast algorithms in computational complexity up to about 50% with almost the same visual quality performance.
