The quantitative evaluation of DEM(Digital Elevation Map) is very important to the assessment of the effectiveness for the applied 3D image analysis technique. This paper presents a new quantitative evaluation method of 3D reconstruction process by using synthetic images. The proposed method is based on the assumption that a preacquired DEM and ortho-image should be the pseudo ground truth. The proposed evaluation process begins by generating a pair of photo-realistic synthetic images of the terrain from any viewpoint in terms of application of the constructed ray tracing algorithm to the pseudo ground truth. By comparing the DEM obtained by a pair of photo-realistic synthetic images with the assumed pseudo ground truth, we can analyze the quantitative error in DEM and evaluate the effectiveness of the applied 3D analysis method. To verify the effectiveness of the proposed evaluation method, we carry out the quantitative and the qualitative experiments. For the quantitative experiment, we prove the accuracy of the photo-realistic synthetic image. Also, the proposed evaluation method is experimented on the 3D reconstruction with regards to the change of the matching window. Based on the fact that the experimental result agrees with the anticipation, we can qualitatively manifest the effectiveness of the proposed evaluation method.

The book is a footnote of life and memory, a sign of knowledge and intelligence, including divinity and reason, idols and destruction, praise and curse, arrogance and prejudice, truth and falsehood. The past emperors, monarchs, priests, and rulers have been controlled or slaughtered by censorship and prohibition, burning and destruction, etc. In ancient history, archaeology, war history, cultural history, and library and information science, many studies have been conducted on the burning and destruction of books, but the Western perspective is dominant, and there are nationalistic approaches and logical leaps. This study traced the truth about the destruction of the Royal Library of Alexandria in Egypt, destruction of the Baghdad libraries by the Mongol Empire, and burning more than 200,000 volumes of Korean historical documents of Japanese Government-General in Korea among the major bibliocausts with many mysteries and controversial issues in the East and West. As a result, the Royal Library of Alexandria is most likely destroyed under the rule of the Roman Empire. The massacre of the Baghdad library by the Mongolian army is a historical fact, not the manipulation and extreme exaggeration of western society. And Korean historical documents have been stolen and burned by the Government-General of Chōsen for 35 years and should be recognized as '200,000 + α'. Lastly, On the premise of excavating historical materials, research to investigate the truth behind the blibiocaust or libricide should be continued.

This study was examined the effective nonverbal behavior cues of detecting suspects' lies in the investigation scene. In order to search the suspects who drank the alcohol liquor without a permission, 18 soldiers were interviewed. 8 solders had drunken alcohol and had lied when was asked(lie group). The other 10 soldiers hadn't drunken alcohol and had told the truth(truth group). The mean frequencies of nonverbal behaviors were compared lie group with truth group. The following behaviors were measured by frequency: vocal characteristics (high pitch of voice, speech hesitations, speech error, frequency of pauses, period of pauses, latency period), facial characteristics (gaze, smile, touching face, blinking, facial micro-expression), body movement (illustrators, hand and finger movement, leg and foot movement, head movement, trunk movement, shifting position). As results, this study found that deception cues were periods and frequencies of pause, micro-expression, head movements. The lie group had less periods and frequencies of pause, and more micro-expression, head movements than truth group. But, this study didn't found Othello's error cues.

가상시험장은 양질의 시험 서비스를 보다 적은 비용으로 신속하게 제공하면서 실제 시험시에 발생할 수 있는 새로운 시험공간의 확보, 안전문제, 오염방지, 민원등에 효과적으로 대처할 수 있는 기술로 판단된다. 가상시험장의 효용가치는 가상시험 결과와 실제시험 결과의 근접성에 의해 결정되므로 모델링과 시뮬레이션 기술 개발과 더불어 Ground Truth Data의 축적이 선행되어야 성공적인 가상시험장 구축을 기대할 수 있다.

The paper argues for the necessicity of revising many fundamental concepts that we use in everyday situations and in communication such as reality, thought, language, the world and finally the truth. The paper develops the argument that what the word ′truth′ actually signifies cannot be addressed just by explicating what philosophy, science or even religion denote but that it can only be answered fully by the study of language and therefore in a larger context linguistics. Language is the very tool that enriches the communication between one another due to its diverse significations that one may use when expressing one′s views, thereby making life more enjoyable. The paper develops why the above corresponding argument should be justified by developing three outstanding views as follows. The world or reality is indistinguishable from the common worldview that we associate with without the means of language. That the worldview is in essence inseparable from the mental and intellectual representation of it and the only means of expression lies with language. And finally, that the language is a complex signification in itself in every aspect. Language in short is the very essence of what we define as being ′poetic.′ With these arguments in mind, we may once again ponder the signification of Nietzsche′s words when he states that "to see science through the lens of art, and art through the lens of life."

Wheelchair users have a difficulty in managing their weight because there is lack of measure systems and even though the users have the system, it costs too much. Thus, purpose of this study is for developing the portable weight scale automatic device to help wheelchair users by monitoring their weight on the wheelchairs in real time. Portable weight scale automatic device composed by four strain gauges, and the device was connected with mobile phone so that wheelchair users were able to check their weight in real time. In order to evaluate the device performance, 10 normal subjects and 10 disabled subjects participated in this study. The subjects' truth weight and measured weight by the device are compared. The weigh difference within normal subjects was $0.75{\pm}0.80kg$, and the weigh difference within disabled subjects was $1.02{\pm}0.74kg$. Difference between the truth weigh and the measured weigh were not statistically different. The reason for this error occurred is inaccuracy of the loadcell installation and calibration. If this problems get solved, the measured indicator is expected to help wheelchair users to manage their weight.

This paper proposed image matching technique that find out the truth of the wild ginseng through smart phone when the common person discovered a plant like a wild ginseng. Also sharing a location and information by SNS, we can improve the probability of wild ginseng discovery. Image matching technique using OpenCV porting in android finds out the truth of the wild ginseng with comparing existing it. Thus we are able to compare and analysis them in our application program. For more verification, we added marking function of wild ginseng position for information sharing between users.

In this study, we propose a novel technique of software clustering to recover the software module-view by using the dependency and author entropy of modules. The proposed method first performs clustering of modules based on structural and logical dependencies, then it migrates selected modules from the clustered result by utilizing the author entropy of each module. In order to evaluate the proposed method, we calculated the MoJoFM values of the recovery result by applying the method to open-source projects among which ground-truth decompositions are well-known. Compared to the MoJoFM values of previously studied techniques, we demonstrated the effectiveness of the proposed method.

In this paper, we describe a measurement technique for the backscattering coefficient and ground truth of a vegetation canopy in detail. A simple microwave backscattering model for vegetation canopies is verified by being compared with this measurement. An R-band$(1.7\sim2.0GHz)$ scatterometer system is used to measure the backscattering coefficient of a vegetated area in the Han-river park for various incidence angles and a wide range of the soil moisture contents. It is found that the model agrees quite well with the measurements for co-polarized radar backscatter, and needs a correction for cross polarized radar backscatter.
