The information on the cloud presence within a instantaneous field of view is the first step toward the derivation of many other geophysical parameters. Here, we first applied the current MODIS cloud detection algorithm developed by University of Wisconsin and compared the results to a visual interpretation of composite data, especially during the daytime. Most of cases, the detection algorithm performs very well, except a few cases with over-detection. One of the reasons for the false detection is due to the time independent use of land information which affects the threshold values of visible channel test. In the presentation, we show detailed analysis of the current cloud detection algorithm and suggest possible way to overcome the current shortfall.

In this paper, we propose an efficient algorithm for non-streaming synchronized data processing based on ATSC-DASE in terrestrial digital data broadcasting services. Non-streaming synchronized data is encapsulated in DSM-CC sections with PTS(presentation time stamp) values associated with A/V and it is transmitted in a form of MPEG-2 TS(transport stream). At the receiver, the transmitted A/V data are processed by PC based set-top box(STB) in real-time, and the transmitted non-streaming synchronized data is also stored at the STB and is displayed at right time by the proposed algorithm. To verity the proper operation of the proposed algorithm, we make a scenario for non-streaming synchronized data by XML, and finally we are able to display it properly by using declarative application(DA) browser.

Background: Multiple myeloma is the most common malignant plasma cell dyscrasia and ranks second among primary haematological malignancies. This study describes the epidemiologic, clinical and pathologic profile of monoclonal gammopathies seen in the University Hospital of the West Indies (UHWI), a tertiary care referral centre. Materials and Method: A retrospective analysis of 85 cases diagnosed at UHWI over the 5-year period 2003-2007 was conducted. The cases were identified from the bone marrow records as well as the computerized database of the Medical Records Department. Clinical presentation, family and personal history and demographic data were retrieved. Haematological and biochemical results were also analyzed. Results: There were 85 patients diagnosed with monoclonal gammopathies. The M:F ratio was 1.2:1 and the mean age was $65.7{\pm}1.3$ years. Eighty percent of the patients had skeletal pain and 40% experienced weight loss. Of the patients experiencing bone pain 56.7% had multiple lytic lesions, 26.7% had pathological fractures and 26.7% had compression fractures. Seventy-four patients (87.1%) had a haemoglobin level <12.0 g/dL with 52.9% having values <8.0 g/dL. Renal impairment was evident at diagnosis in 36.5%. Hypercalcemia was seen in 26.5% and hyperuricemia in 45.9%. Of the 79 patients who had serum protein electrophoresis performed, 77.2% had at least one monoclonal band and of these 24.6% had a monoclonal protein also present on urine protein electrophoresis. Conclusions: The demographic profile in this group of patients is largely similar to other studies in predominantly Caucasian populations; however there was a notable increase in prevalence of severe disease at presentation, with the majority of patients presenting at the most advanced stage. It is probable that these differences reflect socioeconomic factors and not merely inherent ethnic variation in disease biology.

Purpose: Celiac disease, an autoimmune enteropathy triggered by exposure to gluten, is not uncommon in South Jordan. However, its prevalence is underestimated due to lack of physician awareness of the diversity of disease presentation. The clinical spectrum includes classic gastrointestinal manifestations, as well as rickets, iron-deficiency anemia, short stature, elevated liver enzymes, and edema. Our goal was to evaluate celiac disease presentation in clinically diagnosed children. Methods: Retrospective study included all children diagnosed with celiac disease between September 2009 and September 2015. Hospital charts were reviewed. Demographic data, clinical characteristics, and follow-up were recorded. Results: Thirty-five children were diagnosed with celiac disease during the study period. Mean age${\pm}$standard deviation was $6.7{\pm}3.8$ years (range, 2.0-14 years). There were 17 (48.6%) female patients. The average duration between onset of symptoms and diagnosis was $16.3{\pm}18.7$ months. Fifteen (42.9%) patients presented with classic malabsorption symptoms, whereas 7 (20.0%) patients presented with short stature. Positive tissue transglutaminase antibodies (tTg)-immunoglobulin A (IgA) was seen in 34 (97.1%) patients. The one patient with negative tTg-IgA had IgA deficiency. Although tTG-IgA values were not available for objective documentation of compliance, clinical data (resolution of presenting abnormalities and growth improvement) assured acceptable compliance in 22 (62.9%) patients. Conclusion: CD in children may present with diverse picture. Although of the small number, the non-classical presentations are not uncommon in our rural community. Gluten-free diet is the main strategy for treatment and associated with usually correction of laboratory abnormalities and improvement of growth.

Over the past 20 years, constant progress in noise and vibration (NVH) engineering has enabled to constantly advance quality and comfort of operation and use of really any products - from automobiles to aircraft, to all kinds of industrial vehicles and machines - to the extend that for many products, supreme NVH performance has becomes part of its brand image in the market. At the same time, the product innovation agenda in the automotive, aircraft and really many other industries, has been extended very much in recent years by meeting ever more strict environmental regulations. Like in the automotive industry, the drive towards meeting emission and CO2 targets leads to very much accelerated adoption of new powertrain concepts (downsizing of ICE, hybrid-electrical...), and to new vehicle architectures and the application of new materials to reduce weight, which bring new challenges for not only maintaining but further improving NVH performance. This drives for innovation in NVH engineering, so as to succeed in meeting a product brand performance for NVH, while as the same time satisfying eco-constraints. Product innovation has also become increasingly dependent on the adoption of electronics and software, which drives for new solutions for NVH engineering that can be applied for NVH performance optimization of mechatronic products. Finally, relentless pressure to shorten time to market while maintaining overall product quality and reliability, mandates that the practice and solutions for NVH engineering can be optimally applied in all phases of product development. The presentation will first review the afore trends for product and process innovation, and discuss the challenges they represent for NVH engineering. Next, the presentation discusses new solutions for NVH engineering of products, so as to meet target brand values, while at the same time meeting ever more strict eco constraints, and this within a context of increasing adoption of electronics and controls to drive product innovation. NVH being very much defined by system level performance, these solutions implement the approach of "Model Based System Engineering" to increase the impact of system level analysis for NVH in all phases of product development: - At the Concept Phase, to be able to do business case analysis of new product concepts; to arrive at an optimized and robust product architecture (e.g. to hybrid powertrain lay-out, to optimize fuel economy); to enable target cascading, to subsystem and component level. - In Development Phase, to increase realism and productivity of simulation, so as to frontload virtual validation of components and subsystems and to further reduce reliance on physical testing. - During the final System Testing Phase, to enable subsystem testing by a combination of physical testing and simulation: using simulation models to simulate the final integration context when testing a subsystem, enabling to frontload subsystem testing before final system integration is possible. - To interconnect Mechanical, Electronical and Controls engineering, in all phases of development, by supporting model driven controls engineering (MIL, SIL, HIL). Finally, the presentation reviews examples of how LMS is implementing such new applications for NVH engineering with lead customers in Europe, Asia and US, with demonstrated benefits both in terms of shortening development cycles, and/or enabling a simulation based approach to reduce reliance on physical testing.

Background: This study aimed to create and present content that can be used in the dental hygiene ethics process to help dental hygiene students develop desirable work ethics and ethical values. Methods: In order to operate the dental hygiene ethics course in all academic systems, one three-year dental hygiene professor and one four-year dental hygiene professor participated in setting core competencies and learning goals for the dental hygiene ethics course. The class consisted of two credits, two hours of theoretical classes, and class activity sheets developed according to the learning contents and learning topics for each week that can be operated for 15 weeks. Results: The contents of the dental hygiene ethics subject were developed to be conducted as theoretical education and case-oriented discussion classes. The 15-week class consisted of a theory lecture on dental hygiene work ethics (eight weeks), discussions and presentations for ethical decisions based on actual cases related to dental hygiene ethics (four weeks), and the design and presentation of individual professional mission statements and codes of conduct (three weeks). The class data for each week consisted of four stages: "Learning goal-thinking," "open-thinking," "learning content-thinking," and "according to learning goal." Conclusions: In order to establish desirable workplace ethics and ethical values for dental hygiene students, it is necessary to approach education in a way that values understanding and application of dental hygiene practices, legal and ethical standards, ethical decision-making models, and ethical principles.

Background: The purpose of this study is to evaluate if there is a relation between platelet: lymphocyte ratio (PLR) and neutrophil lymphocyte ratio (NLR) values and tumour histology and spread in bladder cancer cases. Materials and Methods: Bladder cancer patients undergoing TUR-M operation, with histopathologically verified diagnosis, followed-up and treated at the Private Medical Park Gaziantep Hospital between 2010 and 2015, have were included in the study. NLR and PLR values were calculated using complete blood count data obtained at the first presentation. Results: A total of 99 patients were included in the study, 7 (7.1%) women and 92 men (92.9%). When NLR was used as the indicator of systemic inflammatory response (SIR), it was determined that, 52 (52.5%) of the patients were SIR negative and 47 (47.5%) SIR positive. No significant relation could be detected between NLR and tumour grade and muscle invasion (p=0.948, p=0.480). When PLR was used as SIR indicator, it was determined that 71 (71.7%) of the patients were found as negative and 28 (28.3%) as positive. No significant relation could be detected between PLR and tumour grade and muscle invasion (p=0.651, p=0.494). Conclusions: In our study we did not detected a relation between tumour histological behavior and PLR and NLR in bladder cancer. However, NLR and PLR are easily calculated, accessible, inexpensive and simple-to-use laboratory data from whole blood counts.

The purpose of this study was development of 'Environmental Science' of high school appropriate to Sixth Natinal Education Curriculum. In view that ultimate aim of environmental education is forming responsible environmental behaviors and the goals of values and behaviors are as important as knowledges and skills, A new environmental text of high school level was developed and it was based on analysis of seven texts and environmental education in Fifth Korean Curriculum. This text have seven units, 1.Habitates : What're the Meanings?, 2.Nuclear Energy: Can't be Avoid?, 3.Acid Rain : What're the Messages", 4.Ethanol : Is this Future Fuel?, 5.Wastes : A New War!, 6.What're the National and Global Environmental Issues? and 7.Our Water: Can Drink, Really? This text was stressed equally in goals of four environmental education and avoided from the array of knowledges. Therefore included various teaching strategies and independent actions of students. 'Open-ended value learning' and 'free behavior learning' in text were special learning parts for aquisition of values and formation of behaviors. To verify the effects of new developed environmental text, the direct learning was carried out by 286 students in total. Post test scores of experimental groups per each units were significantly higher than those of control groups about four goals, respectively. The Results of questionnaires by 50 teachers from five different schools were as follows. For validity of selecting contents for units, 74% of respondents replied positively. For classification and presentation of four goal-groups, 90% replied positively in validity and 82%, in utility. For validity of various teaching strategies, 88% and for the degree of including student-centered independent actions, 86% replied positively. For importances and expected effects of 'open-ended value learning' and 'free behavior learning', showed positive responses respectively, 88%, 92%. Therefore this text is effective to acheive four goals of environmental education equally.

Background: Pancreatic cancer is a distressing disease with a miserable prospects and early recognition remains a challenge due to ubiquitous symptomatic presentation, deep anatomical location, and aggressive etiology. False positives and problems in distinguishing pancreatitis from adenocarcinoma limit the use of CA 19-9 as both disorders can present with similar symptoms and share radiographic physiognomies. This study aimed to assess the relative increase in accuracy of diagnosing the patients with chronic pancreatitis, benign neoplasm of pancreas and adenocarcinomas with CA 19-9, haptoglobin, and serum amyloid A in comparison to CA 19-9 alone. Materials and Methods: This hospital based case control study was carried out in the Departments of Medicine and Biochemistry of Manipal Teaching Hospital, Pokhara, Nepal, between $1^{st}$ January 2010 and $31^{st}$ December 2011. The variables assessed were age, gender, serum CA19-9, serum haptoglobulin, serum Amyloid A. The data were analyzed using Excel 2003, R 2.8.0 Statistical Package for the Social Sciences (SPSS) for Windows Version 16.0 (SPSS Inc; Chicago, IL, USA) and the EPI Info 3.5.1 Windows Version. Results: Out of 197 cases of pancreatic disease, maximum number of assumed cases were of adenocarcinoma of pancreas (95). Number of males (59) were more than females (36) in assumed cases of adenocarcinoma of pancreas. The mean values of CA19-9 raised considerably in cases of chronic pancreatitis, benign neoplasm and adenocarcinoma of pancreas when compared to controls. The highest augmention in CA19-9 values were in cases of adenocarcinoma of pancreas. The p-value indicates that in cases of chronic pancreatitis, there was not significant increase in precision of diagnosis. Conclusions: These statistics established that haptoglobin and SAA are useful in discriminating cancer from benign conditions as well as healthy controls.

We performed a comprehensive comparison between GPS Global Ionosphere Map (GIM) and TOPEX/Jason (T-J) TEC data for the periods of 1998~2009 in order to assess the performance of GIM over the global ocean where the GPS ground stations are very sparse. Using the GIM model constructed by CODE at University of Bern, the GIM TEC values were obtained along the T-J satellite orbit at the locations and times of the measurements and then binned into various geophysical conditions for direct comparison with the T-J TECs. On the whole, the GIM model was able to reproduce the spatial and temporal variations of the global ionosphere as well as the seasonal variations. However, the GIM model was not accurate enough to represent the well-known ionospheric structures such as the equatorial anomaly, the Weddell Sea Anomaly, and the longitudinal wave structure. Furthermore, there seems to be a fundamental limitation of the model showing the unexpected negative differences (i.e., GPS < T-J) in the northern high latitude and the southern middle and high latitude regions. The positive relative differences (i.e., GIM > T-J) at night represent the plasmaspheric contribution to GPS TEC, which is maximized, reaching up to 100% of the corresponding T-J TEC values in the early morning sector. In particular, the relative differences decreased with increasing solar activity and this may indicate that the plasmaspheric contribution to the maintenance of the nighttime ionosphere does not increase with solar activity, which is different from what we normally anticipate. Among these results, the plasmaspheric contribution to the ionospheric GPS TEC will be presented in this talk and the rest of it will presented in the companion paper (poster presentation).
