Objective: The objective of our present study was to assess the role of serum amyloid A (SAA) in stages and prognosis of renal cell carcinoma. Material and Methods: It was a hospital based retrospective study carried out in the Department of Medicine and Biochemistry of Manipal Teaching Hospital, Pokhara, Nepal between $1^{st}$ January 2008 and $31^{st}$ December 2011. The variables collected were SAA, CRP. Approval for the study was obtained from the institutional research ethical committee. Quantitative analysis of human SAA and C-reactive protein (CRP) was performed by radial immune diffusion (RID) assay for all cases. Results: Of the 422 total cases of renal cell carcinoma, 218 patients had normal and 204 abnormal SAA. SAA levels were grossly elevated in T3 stage ($122.3{\pm}SD35.7$) when compared to the mean for the T2 stage ($84.2{\pm}SD24.4$) (p value: 0.0001). Similarly, SAA levels were grossly elevated in M1 stage ($190.0{\pm}SD12.7$) when compared to the M0 stage ($160.9{\pm}SD24.8$) (p: 0.0001). There was no significant association with elevated CRP levels ($209.1{\pm}SD22.7$, normal $199.0{\pm}SD19.5$). Conclusion: The validity of SAA in serum as being of independent prognostic significance in RCC was demonstrated with higher levels in advanced stage disease.

Xanthoceras sorbifolium is considered as bio-energy crops owing to the high oil content from kernel. This study was performed to analyze calorific value, crude ash content, ultimate ratio, crude lipid and fatty acid composition among seed sources. Calorific values ranged from $4,526.0\;cal\;g^{-1}$ to $7,377.2\;cal\;g^{-1}$ in seeds and kernels showed the highest value. Calorific values and crude ash contents were observed as significant difference among plantations and/or individuals (p>0.05). Kernel from SD-F plantation showed the highest calorific value and lower crude ash content. C content comprised 63.4%, the highest levels was detected from SD-F (64.8%). Crude lipid content in kernel observed as 54.5 g $100\;g^{-1}$ from SD-F. In contrast it was determined the lowest value from LN-JARS as 46.5 g $100\;g^{-1}$. The fatty acid composition of kernel was determined to those of oleic acid (31.3%) and linoleic acid (38.1%) from SD-F and LN-JARS. These results will be offered to useful information for breeding materials selection.

We developed an SD-OCT (Spectral Domain-Optical Coherence Tomography) system which uses a GPU (Graphics Processing Unit) for processing. The image size from the SD-OCT system is $1024{\times}512$ and the speed is 110 frame/sec in real-time. K-domain linearization, FFT (Fast Fourier Transform), and log scaling were included in the GPU processing. The signal processing speed was about 62 ms using a CPU (Central Processing Unit) and 1.6 ms using a GPU, which is 39 times faster. We performed an in-vivo retinal scan, and reconstructed a 3D visualization based on C-scan images. As a result, there were minimal motion artifacts and we confirmed that tomograms of blood vessels, the optic nerve, and the optic disk are clearly identified. According to the results of this study, this SD-OCT can be applied to real-time 3D display technology, particularly auxiliary instruments for eye operations in ophthalmology.

The maintenance of school building is pivotal issue. However, it is difficult to obtain basic analysis data for LCC(Lifecycle Cost) analysis and maintenance planning of school building. Therefore, this study proposed System Dynamics(SD) techniques to make maintenance decisions for school building. The interaction between the major parameters related to the aging of a building, maintenance activities, and cost were expressed in Causal Loop Diagram. Based on this, the formula for the relationship between causal maps was defined and converted to Stock and Flow Diagram. Through the completed SD model the 50-year plan of 214 educational building were tested by considered in account budget, maintainability, and budget allocation opinions. As a result, the integrated SD model demonstrated that it can support strategic decision making by identifying the status class and LCC behavior of school buildings by scenario. According to the scenario analysis, the rehabilitation action of preventive maintenance that primarily repairs the buildings in condition grade C showed the best performance improvement effect relative to the cost. Therefore, if the proposed SD model is expanded to consider the effects of other educational policies, the crucial performance improvement budget can be estimated in the long-term perspective.

Small angle light scattering and field emission scanning electron microscope have been used to quantify the kinetics of liquid-liquid separation behavior during water vapor(RH52%[$\pm$3%] at 27$^{\circ}C$) quenching (non-solvent induced phase separation, NIPS) of polysulfone/NMP/Alcohol and CPVC/THF/Alcohol, respectively. Time dependence of the position of the light scattering maximum was observed at polysufone dope solutions, confirming spinodal secomposition (SD). while CPVC dope solutions showed a decreased scattered light intensity with a increased q-valuel, indicating nucleation & growth (NG). For the each system, domain growth rate in the intermediate and late stage of phase separation decreased with increasing the number of carbon of alcohol used as additive (non-solvent). Also, in the early stage for SD, the scattering intensity with time was in accordance with Cahns linear theory of spinodal decomposition,[1-3] regardless of types of non-solvent additive.

Background: Breast cancer is the most common cancer among women in most countries of the world. It is ranked first in females in Morocco (accounting for 33.4% of the total cancer burden) and more than 60% of cases are diagnosed at stage III or IV. During the last decade, health-related quality of life (HRQOL) has become an important aspect of breast cancer treatment. The objective of this study was to describe self-reported HRQOL in patients with breast cancer and to investigate its associations with sociodemographic and clinical variables. Methods: A prospective study was carried out in the main oncology centers in Morocco. Quality of life was measured using the Moroccan Arabic versions of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C 30 (EORTC QLQ C30) and the Breast Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-BR23). Statistical analyses were performed using descriptive statistics and multivariate analyses. Results: A total of 1463 subjects were included in the study, with a mean age of 55.6 (SD. 11.2) years, 70% being married. The majority had stage II (45.9%) and a few cases stage IV (12.9%) lesions. The participants' global health mean score was 68.5 and in "functional scales", social functioning scored the highest (Mean 86.2 (SD=22.7)). The most distressing symptom on the symptom scale was financial difficulties (Mean 63.2 (SD=38.2)). Using the disease specific tool, it was found that future perspective scored the lowest (Mean 40.5 (SD=37.3)). On the symptom scale, arm symptoms scored the highest (Mean 23.6 (SD=21.6)). Significant mean differences were noted for many functional and symptom scales. Conclusion: Our results emphasized that the general HRQOL for our study population is lower than for corresponding populations in other countries. This study provided baseline information on the quality of life for a large sample of Moroccan women diagnosed with breast cancer.

Introduction: Breast cancer is the most common cancer among Jordanians. Breast cancer patients suffer from several negative consequences after treatment and these include pain, fatigue, sexual problems, appearance and body image concerns, with psychological dysfunction. This could affect the patient quality of life and psychological well-being. To the best of our knowledge, there is no published quantitative data on the quality of life and psychological well-being of breast cancer patients in Jordan. The objective of this study was to obtain such data and assess predictors with calculated scores. Methods: In this cross-sectional study conducted among breast cancer patients in Jordan diagnosed in 2009 and 2010, assessment was performed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the Breast Module (QLQ-BR23) and the Hospital Anxiety and Depression Scale (HADS). Clinical, demographic and psychosocial indicators that could predict patient quality of life scores were collected. Results: The number of patients interviewed was 236 (mean age=$50.7{\pm}10.7$ years). The mean Global Health score for the QLQ-C30 was $63.7{\pm}20.2$ SD. Among functional scales, "social functioning" scored the highest ($mean=78.1{\pm}28.6$ SD), whereas "emotional functioning" scored the lowest ($mean=59.0{\pm}SD\;33.5$). For the QLQ-BR23, the worst scores within the functional scales were for "body image" ($mean=52.1{\pm}36.8$ SD) and "future perspective" ($mean=52.9{\pm}38.5$ SD). The worst symptom was "upset by hair loss" ($mean=69.8{\pm}43.0$). The mean HADS scores was $18.{\pm}9.0$ SD. Out of study participants, 53% scored abnormal on the anxiety scale and 45% on the depression scale. Severe depression and severe anxiety were detected among 8% and 14% of study participants, respectively. Statistically significant predictors for individual scores were similar to those reported in published studies, such as the presence of recurrence since baseline, family history of cancer, low educational status, current social problems, extent of the disease, presence of financial difficulties, and employment status. Conclusions and Recommendations: Breast cancer survivors in Jordan have overall good quality of life scores when compared with patients from Western countries. However, their psychological wellbeing is more impaired. There is an urgent need for psychosocial support programs and psychological screening and consultation for breast cancer patients at hospitals of the Ministry of Health in Jordan.

본 논문에서는 Full HD TV를 위한 화질 개선 VDP( Video Display Processor)의 SoC( System on a Chip) 구현을 위한 효율적인 하드웨어 구조를 제안한다. 제안한 구조는 SoC 설계의 한 방법으로써 효율적인 버스 구조와 유연성 있는 인터페이스를 지원하여 실시간 비디오 처리를 가능하게 한다. VDP를 구성 하고 있는 비디오 IP 들은 고화질 영상 제공 및 화질 개선을 위한 목적으로 설계 되었고, 각각의 IP는 실시간성 보장 및 SoC의 하드웨어 통합을 위해서 Avalon 인터페이스가 사용되었다. 이는 설계시간을 단축하고, IP 검증과 특히 SoC를 구성하는데 있어서 IP 추가 삭제 및 변경 등이 용이함으로써 사용자의 편리성을 높여준다. 또한 SoC의 임베디드 소프트웨어는 실시간으로 비디오 세부 항목 설정 및 데이터 전송 방식 설정 등을 제어할 수 있음으로써 유연성 있는 실시간 처리 시스템을 구현할 수 있다. VDP의 SoC 구현은 CyclonIII SoPC(System on a Programmable Chip) 플랫폼 상에서 구현되었으며, 실험 결과 SD 해상도의 입력 영상을 Full HD 해상도로 변환시킴으로써 고화질 영상을 획득 할 수 있다.
