  • The close-range photogrammetry is a surveying technique the acquiring the 3D object from 2D geometric appearance shown in the image. Camera treatment is relatively so simple. Camera position refer to the object can be freely adjusted by locating the exposure station at any site. So it is used effectively on a small area or object for survey. In this study, using the digital camera which has capacity of keeping numerical value by itself and easy carrying, we analyze the positioning error according to various change of photographing condition. Also we try to find a effective method of acquiring basis data for 3D monitoring of high-accuracy in sub-pixel degree thorough digital close-range photogrammetry with bundle adjustment for local terrain model generation.

  • The previous control point surveying, being standardized by trigonometric point which hasn't been unified in the whole country and producing put into operation through complex calculation process, has many problems about accurate results and economic side. Because most of trigonometric points that standardize a present surveying are in situation in top of the mountain, there are many difficulties in solving sight problems. Since trigonometric points are far away from one another, Differences are created because of limitation of point distance, observatory network construction and distribution of error. In the information age, the study about acquiring three dimension surveying information that uses GPS has been processed as fast as acquiring topography information is getting important gradually. For utilizing GPS in surveying work, deciding transformation 7-Parameters that changes data about location information which is received by GPS receiver is important. In this study, it is decided transformation 7-Parameters that can be used in ka-pyoung area by using GPS surveying production that had put into operation.

  • Today, we have often heard that information is a national resources, perhaps our most important national resources, and that government should recognize this and develop a national policy for the effective management and use of information. But traditionally the library has played a rather passive role in selecting, acquiring, preserving and transfering information. Now we have faced greater and much more diverse and more urgent demand from users and we have to cope effectively with a massive increase in volume and in cost in selecting, acquiring, storing and retrieving information. Individual libraries can no longer keep pace with the published outputs of the world. The solution of these problems lies in "national planning and in cooperation through inter-library cooperation and in the application of data processing to library operations." Also at the national level lies the responsibility for total bibliographic control of the national information output and for the interfacing of this with other national and international systems; for the development, adoption and maintenance of, standards in all areas affecting library work; for the provision of services based on centrally created and maintained bibliographic data files, and for planning and policy development of the national information system.

  • In this study, we introduce trends in neural-network-based deep learning research applied to dialogue systems. Recently, end-to-end trainable goal-oriented dialogue systems using long short-term memory, sequence-to-sequence models, among others, have been studied to overcome the difficulties of domain adaptation and error recognition and recovery in traditional pipeline goal-oriented dialogue systems. In addition, some research has been conducted on applying reinforcement learning to end-to-end trainable goal-oriented dialogue systems to learn dialogue strategies that do not appear in training corpora. Recent neural network models for end-to-end trainable chit-chat systems have been improved using dialogue context as well as personal and topic information to produce a more natural human conversation. Unlike previous studies that have applied different approaches to goal-oriented dialogue systems and chit-chat systems respectively, recent studies have attempted to apply end-to-end trainable approaches based on deep neural networks in common to them. Acquiring dialogue corpora for training is now necessary. Therefore, future research will focus on easily and cheaply acquiring dialogue corpora and training with small annotated dialogue corpora and/or large raw dialogues.

  • Purpose: This study examined medical college students' perception of euthanasia and analyzed whether there were significant differences in their perceptions based on their grade, religion, and economic situation. Methods: A questionnaire comprising items relating to students' knowledge about euthanasia, their economic situation relationships with patients, and the extent to which euthanasia would be allowed depending on the patient's condition. Results: Results by age and school year revealed there were no statistically significant differences concerning permissible levels of euthanasia. However, differences were found in the permissible levels of euthanasia according to changes in the patients' condition. Conclusion: It can be interpreted that students' personal values and religion had a great effect on the perception of euthanasia than the process of acquiring medical knowledge. The religion or values they have in your life affect your perception of euthanasia more than the process of acquiring and learning medical knowledge. The suffering of patients is the most important priority and it supports euthanasia on the grounds of relieving psychological distress for patients' families and the right of every patient to die gracefully. Nevertheless, considering the possibility of patient survival and euthanasia being used for murder, it is necessary to legislate the use of euthanasia and have the appropriate qualifications for its administration on patients.

  • In general, similar or previous projects are mainly referred to in order to derive operational test and evaluation(OT&E) items after acquiring weapon system. The idea that a more systematic method is needed is spreading because some of OT&E items derived in this process are redundant or unnecessary. Therefore, in this topic, we plan to use WBS, a tool that classifies components into a hierarchical structure and manages development easily to achieve the weapon system development goal. In addition, the WBS tool is applied to the medium-sized standard vehicle project, which is currently being research and developed, to effectively derive OT&E items. As a result of deriving OT&E items by applying WBS to the vehicle development field and electric devices of the medium-sized standard vehicle project, the operability and relationship were judged early, and then contents of the evaluation items could be written substantially while working on environmental adaptability. In the future, it is judged that the efficiency will be increased if the method discussed in this paper is applied when deriving the OT&E items from the R&D development project.

  • Acquiring high-quality images in control and measurement systems is one of the important factors. Among image acquisition technologies, SFF (Shape from Focus) is a technology for recovering a 3D shape by acquiring 2D images with different focus levels by moving an object at a predetermined step size along the optical axis. For SFF, when an object is moved at a constant step size, mechanical vibration, referred as jitter noise, occurs in each step along the optical axis. In this paper, a new state estimation filter is designed and applied for reducing the jitter noise. For the application of the proposed method, the jitter noise and focus curves are modeled as Gaussian function. Experimental results demonstrate the effectiveness of proposed method.
