Although midgut volvulus is clinically characterized by bilous vomiting and abdominal distention, plain abdominal X-ray is usually non-specific and therefore it can be misdiagnosed to other diseases. Upper gastrointestinal contrast study and computed tomography have been used as a routine diagnostic tool but it takes cost and time. Abdominal ultrasonography is a relatively good alternatives in diagnosing midgut volvulus and it relatively saves cost and time. But case presentation of midgut volvulus diagnosed with abdominal ultrasonography are rarely found in literature. We experienced a 6 month old girl who had come to our hospital with bilous vomiting and was diagnosed as midgut volvulus with ultrasonography. Thus we report this case with the presentation of typical ultrasonographic findings of midgut volvulus.

In this study we examined the context effects in reading Hangul (Korean alphabets) in normal and low vision, using the two different reading techniques, self-paced reading (Experiment 1) and rapid serial visual presentation (Experiment 2). We compared the reading speed of participants with normal or low vision in sentences vs. randomly ordered words. The results from both experiments showed that the reading speed of participants with low vision slowed significantly relative to those with normal vision. However, the patterns in the size of context effects were different in the two experiments. The context effects were larger in low vision than in normal vision in self-paced reading, but they were smaller in low vision than in normal vision in RSVP. This result indicates that context may make a greater contribution for readers with low vision than for readers with normal vision when sufficient time is allowed to read; in contrary, its contribution is smaller for readers with low vision than for readers with normal vision when there is time limitation for reading.

Background: Resection rates of lung cancer are low in general and especially in countries like Nepal. Advanced stage at presentation and poor general condition of the patient are the usual causes. Materials and Methods: In this prospective observational study, one hundred cases of lung cancer who presented at the Thoracic Surgery Unit between October 2011 and October 2012 were included. Results: Those aged in the $6^{th}$ and $7^{th}$ decades together accounted for 72/100 patients. The male to female ratio was 2:1. There was a mean-$29.2{\pm}14.2$ pack yrs smoking history with only five non-smokers. Seventy-six patients presented with locally advanced disease while 21 had metastases. Only three had local disease. The average time between onset of symptoms to first contact with a doctor was $2.3{\pm}5.3$ months (range: 0-35.6 months). Average time between first contact to referral was $50.4{\pm}65.7$ days (range-0-365). Only three patients were resected, one after neo-adjuvant chemotherapy. Advanced disease was the cause of unresectability in 95 cases. One of three patients with local disease had pulmonary functions allowing the warranted resection. $N_2$ disease with $T_{1-3}$ on CT scan was found in 47. Three of these patients underwent mediastinoscopy and all confirmed uninvolved $N_2$. Conclusions: Lung resection rates in our center remain low. Late presentation leading to advanced disease and poor pulmonary reserves preclude resection in most cases. More liberal use of mediastinal staging and better assessment of pulmonary functions may allow us to improve resection rates.

Although data analysis in earlier days had been sufficiently done only by character user interface, users of these days are more used to the graphic user interface and the requirements for the user interface are gradually varying and increasing. In order to meet users' various wants and needs and to develop well-equipped interface, not only software developers but also professional designers who can complement the technique of the developers are needed. But in reality there are many restrictions and difficulties for developers and designers to work together cooperatively. Moreover, developing user interface in use of 3D type of graphics and animation techniques causes the rise of the developing cost. The thesis attempts to design and implement 3D visualization for real-time sensor data collected by the various environmental sensor and measuring devices, by using WPF (Window Presentation Foundation) which can make both developers and designers work together cooperatively and which makes it possible to implement various multimedia functions such as a 2D and 3D type of graphics, animation techniques, and an acoustic effect.

Purpose: There is a lack of scholarly reports on pediatric emergency department (PED) exposure to hyperbilirubinemia. We aimed to describe the epidemiology of hyperbilirubinemia in patients presenting to a PED over a three-year period. Methods: This was a retrospective cohort study, completed at an urban quaternary academic PED. Patients were included if they presented to the PED from 2010 to 2012, were 0 to 18 years in age, and had an elevated serum bilirubin for age. A chart review was completed to determine the incidence of hyperbilirubinemia, etiology, diagnostic work up and prognosis. The data set was stratified into four age ranges. Results: We identified 1,534 visits where a patient was found to have hyperbilirubinemia (0.8% of all visits). In 47.7% of patients hyperbilirubinemia was determined to have arisen from an identifiable pathologic etiology (0.38% of all visits). First-time diagnosis of pathologic hyperbilirubinemia occurred in 14% of hyperbilirubinemia visits (0.11% of all visits). There were varying etiologies of hyperbilirubinemia across age groups but a male predominance in all (55.0%). 15 patients went on to have a liver transplant and 20 patients died. First-time pathologic hyperbilirubinemia patients had a mortality rate of 0.95% for their initial hospitalization. Conclusion: Hyperbilirubinemia was not a common presentation to the PED and a minority of cases were pathologic in etiology. The etiologies of hyperbilirubinemia varied across each of our study age groups. A new discovery of pathologic hyperbilirubinemia and progression to liver transplant or death during the initial presentation was extremely rare.

Although the accuracy of handwritten character recognition based on deep networks has been shown to be superior to that of the traditional method, the use of an overly deep network significantly increases time consumption during parameter training. For this reason, this paper took the training time and recognition accuracy into consideration and proposed a novel handwritten character recognition algorithm with newly designed network structure, which is based on an extended nonlinear kernel residual network. This network is a non-extremely deep network, and its main design is as follows:(1) Design of an unsupervised apriori algorithm for intra-class clustering, making the subsequent network training more pertinent; (2) presentation of an intermediate convolution model with a pre-processed width level of 2;(3) presentation of a composite residual structure that designs a multi-level quick link; and (4) addition of a Dropout layer after the parameter optimization. The algorithm shows superior results on MNIST and SVHN dataset, which are two character benchmark recognition datasets, and achieves better recognition accuracy and higher recognition efficiency than other deep structures with the same number of layers.

Background: Serum 25-hydroxyvitamin D insufficiency is very common in Pakistan and is often related to inferior prognosis in some cancers but limited data exist for hematopoietic malignancies. This study was conducted to determine the vitamin D insufficiency in B-chronic lymphoid leukemia (CLL) cases at the time of presentation and its possible correlation with clinical staging, hematological parameters and biochemical markers. Materials and Methods: This descriptive cross sectional study was carried at Liaquat National Hospital from January 2011 to June 2013. Sixty patients with B-chronic lymphoid leukemia were enrolled. Complete blood count, vitamin D levels, serum urea, creatinine, uric acid and LDH levels were assessed. Data were compiled and analyzed using SPSS version 21. Results: Out of 60 patients, 42 (70%) were male and 18 (30%) were female. Mean age was $59.0{\pm}9.2years$. The frequency of vitamin D insufficiency was found to be 56.7%. Overall insufficiency was more frequently seen in male gender (40%). Vitamin D insufficiency demonstrated a positive association with low lactate dehydrogenase levels (P=0.005). No links were established with age, clinical stage, hematological and other biochemical markers. Conclusions: Vitamin D insufficiency is high compared with Western studies. Whether normalization of vitamin D insufficiency in deficient B-CLL patients could improve the clinical outcome or delay disease progression will require further studies.

The purpose of this study is to do an in-depth examination of Korean women in their 30's on the characteristics of their online fashion shopping, clothes-wearing, and presentation. In-depth interview and quantitative analysis were conducted as study methods. Results of this in-depth analysis showed that the factor with the most significant influence in their lifestyle was "childbirth." Childbirth was a major factor during fashion shopping and clothes-wearing. Also the results showed that the reason they used online shopping was for convenience, efficiency, rationality, pursuit of information, variety, and hedonism. In particular, women in their 30's had a higher motivation for efficiency and rationality compared to those in their 20's, and of those women, married working women showed the highest preference for fashion soho malls. Meanwhile, full-time homemakers, who pursued rationality, used open markets to search for fashion items based on price. Furthermore, the factors that women in their 30's considered during online shopping were price, design, purpose or situation for wearing the clothing, respectively. Compared to the women in their 20's, they emphasized recommendation, product properties, credibility, economy more than women in their 20's. Factors such as marriage and childbirth were more influential than occupation. Meanwhile, the factors that women in their 30's considered for wearing and presentation were time, place, and occasion(TPO), which all showed high importance in in-depth interview and quantitative analysis. Other factors were 'suitable image to self' and 'covering up body figure.'

The purpose of this study is to analyze the current status of augmented reality picture books, which have been steadily developed since 2010, as a genre of electronic picture books, and to reveal how children's immersion in augmented reality picture books differs from paper picture books. To this end, 30 augmented reality picture books on the market were analyzed according to genre, life theme, implementation method, and augmented reality scene ratio. As a result of the study, it was found that the genre of picture books was in the order of information fairy tales, daily fairy tales, and historical fairy tales, and there were no traditional or fantasy fairy tales. Animals and plants accounted for about half of the life topics, and in some cases, there were only a few or no other life topics. In the augmented reality implementation scene, it consisted of only one page in the early days, but all pages are now possible to implement augmented reality due to technology development, production cost reduction, and improved hardware performance of smartphones. It was found that the augmented reality implementation method used CD-ROM in the early days, but gradually became possible to implement using only mobile phones and tablets that were easy for readers to access. In addition, after presenting four picture books to eight 5-year-old infants, the immersion time was measured and the immersion behavior was observed. As a result, augmented reality picture books showed higher immersion[immersion time, immersion behavior] than paper picture books, but compared by literature genre, life fairy tales were higher in paper picture books and natural fairy tales in augmented reality picture books. It was higher when presenting augmented reality picture books after presenting paper picture books according to the order of presentation of picture book types. The results of this study suggest that more diverse life topics and augmented reality picture books in the genre of children's literature should be developed to increase the utilization of augmented reality picture books. In addition, considering that there are differences in immersion between types, literary genres, and reading experience [presentation order], it is expected to increase the educational effect by using picture books complementarily.

Conventionally the subjective assessment for measuring the human sensibility is always performed after an experiment or a stimulus is terminated. This aftermath method can not. exactly, reflect the human sensibility which is produced at the moment of the presentation of the stimulus. In the present study, a new real-time subjective assessment system is developed. The system is composed of two parts: the sensibility input part and the sensibility evaluation part. The sensibility input part gets the values, which are recorded on the input board using pen-mouse, from the evaluation of each subject on his/her own subjective sensibility for the stimulus. The sensibility evaluation part displays the level of the pleasantness and arousal on one and two dimension in real time. An experiment on the design of the input board that any subject can easily and exactly evaluates one's own sensibility is also included in this study. The system can be used for evaluating the human subjective sensibility in real time, and, also, can be applied to other subjective assessment tests that require real time evaluation.
