The myth reflects the human way of thinking about the world. Therefore, an important part of myth is human creation and role. This study examines the process of human creation in myth and discusses implications for education. The subjects that can be considered from the viewpoint of education are as follows. The status and role of teachers and students, the relationship between teachers and students, how to create or create humans, and the purpose and results of human creation. First, it is the position and role of the teacher. In myth, being like a teacher is a divine being that transcends human ability. In Dangun mythology, Hwanwoong or Shinwoong descended from heaven, and in the Genesis it is the Creator God. In Dangun mythology, the role of the teacher guides the way of becoming a human and provides necessary tasks. In Genesis, the image of the teacher is the Creator God. God plays the role of a teacher who prepares various environments in which learners can work. Second, the status and role of students in myths. In Dangun mythology, students are symbolized by bear and tiger. They go to the teacher with the desire to become human beings. In Dangun mythology, the student is not a passive existence but an autonomous and active image. In Genesis, the appearance of a student is a passive being created by a teacher. Third, the creation of human beings in myth can be seen in terms of educational process and method. In Dangun Myth, the beginning of education is the wish or expectation of learners. Learners eat mugwort and garlic and participate in human learning. In Genesis 1, however, there is no need for a special method, since human beings are created according to the Creator's command. Fourth, the purpose of education can be discussed through the purpose of human creation. In Dangun mythology, the purpose of education is not to live according to instinct but to become human with culture and personality. In Genesis 1, the purpose of human creation is the role of the Creator in creating and managing the world. Therefore, it is the aim of humans to manage the world in an orderly manner. The purpose of education in Genesis 2 is to enable humans to serve the world.

Purpose: The aim of this retrospective study was to investigate the use of a radiopaque tissue fiducial marker (TFM) in the treatment of prostate cancer patients who undergo post-prostatectomy radiotherapy (PPRT). TFM safety, its role and benefit in quantifying the set-up uncertainties in patients undergoing PPRT image-guided radiotherapy were assessed. Materials and Methods: A total of 45 consecutive PPRT patients underwent transperineal implantation of TFM at the level of vesicourethral anastomosis in the retrovesical tissue prior to intensity-modulated radiotherapy. Prostate bed motion was calculated by measuring the position of the TFM relative to the pelvic bony anatomy on daily cone-beam computed tomography. The stability and visibility of the TFM were assessed in the initial 10 patients. Results: No postoperative complications were recorded. A total of 3,500 images were analysed. The calculated prostate bed motion for bony landmark matching relative to TFM were 2.25 mm in the left-right, 5.89 mm in the superior-inferior, and 6.59 mm in the anterior-posterior directions. A significant 36% reduction in the mean volume of rectum receiving 70 Gy (rV₇₀) was achieved for a uniform planning target volume (PTV) margin of 7 mm compared with the Australian and New Zealand Faculty of Radiation Oncology Genito-Urinary Group recommended PTV margin of 10 mm. Conclusion: The use of TFM was safe and can potentially eliminate set-up errors associated with bony landmark matching, thereby allowing for tighter PTV margins and a consequent favourable reduction in dose delivered to the bladder and rectum, with potential improvements in toxicities.

It is very important that analysis of textures in rock, the moving of hydrothermal solution along the structures, epithermal vein textures, mineralization and composition minerals to confirm the hydrothermal ore deposits and ore genesis. The purpose of this study is to confirm the gold mineralization and ore genesis through the moving of hydrothermal solution along the structure lines and epithermal vein textures by using Color-corescanner techniques. The three drilling hole cores of Sunshin Gold Mine in Haenam area in Jeonnam Province were into a digital image data. Digital image data of gold bearing epithermal vein textures were analyzed detaily by Color-corescanner. There are several epithermal vein textures, namely Comb texture, Cavity texture, Bladed texture, Zonal texture, Brecciated texture and Combined texture. Gold mineralization is dominated in vein type textures, but high grade gold are enbedded in brecciated texture. Ore genesis is epithermal gold deposit. This Color-corescanner techniques can cover the missing part of the examine with the naked eye, and can examine closely the situation of ore deposit development and genesis by detail checking the textures in rock, mineralization and so on.

The goals of this papper are not only to maximize of performance but also to reduce the response time for the real-time printed alphabets recognition system using the backpropagation algorithm in the artificial neural network. The Genesis board and MIL(Matrox Image Library) package were used to real-time acquisition, processing and display of images. Through this experiment proved the possibility of real-time recognition processing by comparing response times of the system and proposing the method to reduce of order of the output vectors.

문자영상의 인식분야에서는 다양한 잡음으로 인해 손상된 영상을 개선하는 영상의 전처리 과정을 아주 중요시하고 있다. 본 논문에서는 영상의 객체 윤곽을 보호하면서 충격잡음에 효과적인 비선형 중간값(median) 필터를 먼저 적용하고, 영상객체에 대해 선택적으로 축소하고 확대하는 형태학(morphological) 필터를 직렬로 조합함으로서 선명한 문자 영상을 획득하였고, 좀 더 현실적인 문자를 인식하도록 Genesis 영상처리 보드와 이를 제어하는 MIL(Matrox Image Library) 패키지를 사용하여 실시간적으로 구현해 보았다.

In this paper, we described the unique and novel method to prepare two kinds of electro-active particles, black and white particles with different polarity. The surface of the particles was characterized to be uniform and clean by adopting spray dryer as a tool for genesis of particles; neither surfactants nor high dielectric medium like water was employed during particle preparation step. The other purpose of this study is to investigate the factors that contribute high driving voltage of particlebased display like QR-LPD. We extracted parameters interaction between particle and electrode, and between oppositely charged particles. Here we reported an excellent behavior of particle-based display that showed low operating voltage, high contrast ratio as high as 8:1 without scarification of quick response time. By optimizing the particle size, charge per mass, selection of external additive sets, a lower driving voltage as low as 40V for the particles with $10{\mu}m$ volume average diameter was obtained.

Lung cancer is the most common causes of cancer-related deaths worldwide, and a lack of effective methods for early diagnosis has greatly impacted the prognosis and survival rates of the affected patients. Tumor-initiating cells (TICs) are considered to be largely responsible for tumor genesis, resistance to tumor therapy, metastasis, and recurrence. In addition to representing a good potential treatment target, TICs can provide clues for the early diagnosis of cancer. MicroRNA (miRNA) alterations are known to be involved in the initiation and progression of human cancer, and the detection of related miRNAs in TICs is an important strategy for lung cancer early diagnosis. As Hsa-miR-155 (miR-155) can be used as a diagnostic marker for non-small cell lung cancer (NSCLC), a smart molecular beacon of miR-155 was designed to image the expression of miR-155 in NSCLC cases. TICs expressing CD133 and CD338 were obtained from A549 cells by applying an immune magnetic bead isolation system, and miR-155 was detected using laser-scanning confocal microscopy. We found that intracellular miR-155 could be successfully detected using smart miR-155 molecular beacons. Expression was higher in TICs than in A549 cells, indicating that miR-155 may play an important role in regulating bio-behavior of TICs. As a non-invasive approach, molecular beacons could be implemented with molecular imaging to diagnose lung cancer at early stages.
