Image restoration based on the wavelet filter bank
Lee, Jong-soo,Kim, Ju-hun Research Institute for Science & Technology HONG-I 1997 Hongik Journal of Science and Technology Vol.1 No.-
In this paper, we propose a new way to restore a degraded image using the wavelet transform and filter banks. First, we device a degraded image into 4 subband images using UDWT(Undecimated Wavelets Transform), and then use a proper CLS(Constrained Least Square) filter in each subband. Using a proper CLS filter in each subband, we can save the high frequency components constained in the original images. To reduce the computational load, we propose an algorithm which reconstructs an image from the down-sampled subband images using the wavelet transform. This is a good tade-off between the ISNR(Inverse Signal-to-Noise Ratio) and the calculation time because it reduces the calculation loads significantly in contrast to the degradation in ISNR
Image-guided radiation therapy in lymphoma management
Eng, Tony,Ha, Chul S. The Korean Society for Radiation Oncology 2015 Radiation Oncology Journal Vol.33 No.3
Image-guided radiation therapy (IGRT) is a process of incorporating imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI), Positron emission tomography (PET), and ultrasound (US) during radiation therapy (RT) to improve treatment accuracy. It allows real-time or near real-time visualization of anatomical information to ensure that the target is in its position as planned. In addition, changes in tumor volume and location due to organ motion during treatment can be also compensated. IGRT has been gaining popularity and acceptance rapidly in RT over the past 10 years, and many published data have been reported on prostate, bladder, head and neck, and gastrointestinal cancers. However, the role of IGRT in lymphoma management is not well defined as there are only very limited published data currently available. The scope of this paper is to review the current use of IGRT in the management of lymphoma. The technical and clinical aspects of IGRT, lymphoma imaging studies, the current role of IGRT in lymphoma management and future directions will be discussed.

Written corrective feedback (WCF) is widely used to point students to the grammatical errors in their written work and help reduce them. This paper reports a quasi-experimental study that compared the effectiveness of direct and indirect teacher WCF in a Thai context. One hundred and twenty Thai students at two public universities in southern Thailand were assigned to write argumentative essays within a treatment period; each treatment had 60 students. The feedback was given by four ESL/EFL lecturers at the two universities. Grammatical aspects focused on were tenses, subject-verb agreement, articles, singular/plural nouns, prepositions and adjectives/adverbs. Means for the number of errors were obtained at three points, namely, pretest, immediate posttest and delayed posttest. The findings revealed that time and WCF type as main effects showed differentiated results on all six grammatical aspects. Interaction effects between time and WCF were found for tenses and subject-verb agreement. For between-subjects effects, indirect WCF was more effective than direct WCF. For within-subjects effects, generally the differences in the mean values were significant between pretest and delayed posttest, but not between pretest and immediate posttest. These findings have implications for writing instruction and research in an ESL/EFL tertiary context.
Multiple gastrointestinal melanoma causing small bowel intussusception
Jian Yang Eng,Salehah Tahkin,Huzairi Yaacob,Nor Hayati Yunus,Ahmad Shan Wani Mohamed Sidek,Michael Pak-Kai Wong 대한대장항문학회 2023 Annals of Coloproctolgy Vol.39 No.1
A 61-year-old gentleman presented with small bowel intussusception from small bowel melanoma intussusceptum. He complains of intermittent abdominal distension but no history of intestinal obstruction. Apart from this, he was also symptomatic anemia which required repeated transfusion for the past few months. The contrast-enhanced computed tomography of the abdomen shows an omental mass with small bowel intussusception. He then underwent an exploratory laparotomy with segmental resection of the affected segment. Histopathological examination confirmed primary gastrointestinal melanoma. Multiple small bowel malignant melanoma is a rare disease. It remains a controversial diagnosis as it may be a primary or metastasis from an unidentified or regressed primary cutaneous melanoma. Prompt surgical intervention enables us to obtain tissue diagnosis, prevent complete intestinal obstruction and strategize the goals of treatment for the patient.
Neurovascular Mechanisms in Stroke, Neurodegeneration and Recovery
Lo, Eng-H. The Korean Society of Pharmacology 2006 The Korean Journal of Physiology & Pharmacology Vol.10 No.5
The emerging concept of the 'neurovascular unit' may enable a powerful paradigm shift for neuroscience. Instead of a pure focus on the 'neurobiology' of disease, an opportunity now exists to return to a more integrative approach. The neurovascular unit emphasizes that signaling between vascular and neuronal compartments comprise the basis for both function and dysfunction in brain. Hence, brain disorders are not just due to death of neurons, but instead manifested as cell signaling perturbations at the neurovascular interface. In this mini-review, we will examine 3 examples of this hypothesis: neurovascular mechanisms involved in the thrombolytic therapy of stroke, the crosstalk between neurogenesis and angiogenesis, and the link between vascular dysfunction and amyloid pathology in Alzheimer's disease. An understanding of cell-cell and cell-matrix signaling at the neurovascular interface may yield new approaches for targeting CNS disorders.

It is a stringent challenge to swiftly rehabilitate and strengthen the concrete segments on the metro tunnel that are under the humid environment and vibration fatigue by the locomotives. By means of fatigue experiments under the constant amplitude loading, the repair materials (fiber reinforced polymer (FRP) and polymer matrix (PM)) which can be moisture proof and resist the cyclic load are introduced. Hereafter, a fatigue model of tilt’s fulcrum reinforced concrete (RC) segments under constant amplitude loading are proposed by the calibration of S-N curves through these fatigue test. The fatigue model explains for the (a) scope of pre-damage, (b) mechanical properties of the repaired concrete segments, such as the specific rupture times of cycle and stress-crack opening relation, and (c) effective plastic strain behavior of the RC segments. The results show that the purely PM is an excellent candidate for repairing the fatigue loaded damaged RC segment. It (L-4-2) had an average mechanical behavior for cyclic load bearing compared with the remaining specimens. On the other hand, the numerical model predictions had an approximately 96.00% of agreement with the corresponding test results.

Human pluripotent stem cells (hPSCs), including embryonic stem cells (ESCs) and induced PSCs (iPSCs), represent potentially unlimited cell sources for clinical applications. Previous studies have suggested that hPSCs may benefit from immune privilege and limited immunogenicity, as reflected by the reduced expression of major histocompatibility complex class-related molecules. Here we investigated the global immune-related gene expression profiles of human ESCs, hiPSCs and somatic cells and identified candidate immune-related genes that may alter their immunogenicity. The expression levels of global immune-related genes were determined by comparing undifferentiated and differentiated stem cells and three types of human somatic cells: dermal papilla cells, ovarian granulosa cells and foreskin fibroblast cells. We identified the differentially expressed genes CD24, GATA3, PROM1, THBS2, LY96, IFIT3, CXCR4, IL1R1, FGFR3, IDO1 and KDR, which overlapped with selected immune-related gene lists. In further analyses, mammalian target of rapamycin complex (mTOR) signaling was investigated in the differentiated stem cells following treatment with rapamycin and lentiviral transduction with specific short-hairpin RNAs. We found that the inhibition of mTOR signal pathways significantly downregulated the immunogenicity of differentiated stem cells. We also tested the immune responses induced in differentiated stem cells by mixed lymphocyte reactions. We found that CD24- and GATA3-deficient differentiated stem cells including neural lineage cells had limited abilities to activate human lymphocytes. By analyzing the transcriptome signature of immune-related genes, we observed a tendency of the hPSCs to differentiate toward an immune cell phenotype. Taken together, these data identify candidate immune-related genes that might constitute valuable targets for clinical applications.

Purpose: The aim of this study was to compare the effect of different simulation modalities on knowledge, skill, stress, satisfaction, and self-confidence levels of students receiving undergraduate education in three nursing schools. Method: This was an experimental study. Students applied the scenario of “Respiratory Sounds Assessment” which was prepared according to three different simulation modalities. In the study, the standardized patient, high-fidelity simulation, and partial task trainer were used as simulation modalities. Results: An increase was observed in postpractice knowledge levels of the three groups which had similar knowledge levels before the practice. Virtual Analog Scale stress levels of the students in the standardized patient group were higher than those of others. The students’ mean scores of satisfaction in learning were higher in the standardized patient group. The students in the partial task trainer group had lower scores of self-confidence in learning. Skill scores of the students were lower in the standardized patient practice than those in others. Conclusion: Simulation-based experiences give students the opportunity of experiencing situations they may experience in the actual practice beforehand. Therefore, this may increase their performance in real practices, as reality increases in the standardized patient group.
