Amphibians and reptiles are included in two independent classes which are upper units of animal kingdom and inseparable members of biodiversity in Mongolia as well as important part of ecosystem. If these animals are taken from the ecosystem, that normal natural substance nutrient cycle and energy flow will be destroyed. In order to keep the ecosystem balance, there is a need to study and protect the herpetologcal species same as with other biological groups. When amphibians dominating in Nothern region which has more lakes, streams and ponds, as a true terrestrial animal reptiles are mainly occur in Gobi Desert region of the country. There are 6 species of amphibians in Mongolia belongs to 4 families of 2 orders and 21 species of reptiles in Mongolia belongs to 13 genera 6 families of 2 suorders. Our diversity is low, comparing with the Middle Asia, Northeast Asia and Central Asian herpetoligical species, due to harsh continental climate of Mongolia. From the viewpoint of evolution, whole class of amphibians and reptiles could be a relict and since they are cold-bloooded animal, its very difficult to live in dry and cold climate. Even species diversity is poor, Mongolian herpetological composition is unique, highly adopted in country’s harsh climate and originated a long time ago. There are two main characteristic in herpetilogical species composition of Mongolia. First, marginal population of widely distributed Palearctic species entered. Second, core zone of species originated in Central Asia is Mongolia. Based on these two characteristic, objective and future trend of herpetoligical study might determined. Recently climate changes and human impacts on environment negatively influencing on the marginal population species in Mongolia. In mongolia, totally 6 species of amphibian species are recorded; from class Amphibia, order Urodela, family Hynobiidae one species distributed- Hynobius keyserlingii, from order Anura, family Bufonidae two species: Bufo raddei and Bufo pewzovi, from Hylidae family: Hyla japonica, from Ranidae family 2 species: Rana amurensis and Rana chensinensis. Recently some study including Hynobius keyserlingii in Salamandridae family, but we are preffering previous classification which including the species in independent family “Hynobiidae”. The origin of Mongolian amphibian fauna divided into Central Asia-Mongolia, Siberian - Europe, Eastern and Middle Asia (Munkhbayar, 1973). There are total of 21 species of reptiles in two suborders (snake, lizard) of a order (Squamata) distributed in Mongolia, from these 13 species of 13 genera of 6 families are lizards, as follows Kaspischer even-fingered gecko - Alsophylax pipiens, Przewalski’s wonder gecko - Teratoscincus przewalskii, Gobi naked-toed gecko - Cyrtopodion elongates, Mongolian agama - Laudakia stoliczkana altaica, Toad-head agama - Phrynocephalus versicolor, Sunwather toadhead agama - Ph.helioscopus, Sand lizard - Lacerta agilis, Viviparous lizard - L.vivipara, Mongolian racerunner - Eremias argus, Variegated racerunner - E.vermiculata, Stepperunner - E.arguta, Multiocellated racerunner - E.multiocellata and Gobi racerunner - E.przewalskii, and 8 species are snakes as follows Tatar sand boa - Eryx tataricus, Slender racer - Coluber spinalis, Steppes ratsnake - Elaphe dione, Amur rat snake - E.schrenckii, Grass snake - Natrix natrix, Steppe ribbon racer - Psammophis lineolatus, Northern viper - Vipera berus and Halys pit viper - Gloydius halys. The origin of Mongolian reptilian fauna divided into three complex groups (Peters, 1982): West Palearctic forest centered originated species (Viviparous lizard, Grass snake and Northern viper), East Palearctic forest centered originated species (Mongolian racerunner, Halys pit viper and Steppes ratsnake), and Desert centered originated species. Desert centered originated species divided into as complex of Turan (Sunwather toadhead agama, Squeaky pygmy gecko, Stepperunner, Tatar sand boa and Steppe ribbon racer) complex of Tuvd (Mongolian agama), and complex of Mongolia (Plate-tailed gecko, Tuva toad-head agama, Gobi racerunner, Variegated racerunner and Slender racer). Also some researchers divided the fauna as follows Euro-Siberian cool zone, Manjuur, Central Asian, South Palearctic (Asian) and Palearctic and then these species included in Central Asian complex such as Sunwatcher toadhead agama, Mongolian agama, Plate-tailed gecko, Gobi naked-toed gecko, Mongolian racerunner, Multiocellated racerunner, Gobi racerunner and Slender racer (Orlova et al., 1986). At the second International Mongolian Biodiversity Databank Workshop (11-15 September, 2006), participants assessed the status of 27 Mongolian reptile and amphibian species using the IUCN Red List Categories and Criteria. The assessments revealed a number of trends affecting the amphibians and reptiles of Mongolia. Six Mongolian reptile and amphibian species were identified as regionally threatened. Of these, four species are amphibians and two are reptiles. One species, the stepperunner (Eremias arguta) is categorized as Data Deficient. This does not necessarily imply that it is facing a lower risk of extinction than those identified as threatened, but highlights a requirement for more extensive research (Terbish et al.,2008). Steppes ratsnake and Halys pit viper are in 8 biotopes, Mongolian toad is in 6 biotopes, Mongolian racerunner is in 5 biotopes, Siberian salamander, Siberian wood frog, Asiatic grass frog are in 2 biotopes, European grass snake, Steppe ribbon racer are in a biotope. Also lets discuss results of some sites’ estimation. About 60 Asiatic grass frogs are estimated from the 1000 m transect at bank of Dagsh River in Dariganga. While 14 Asiatic grass frogs are estimated from the 1000 m transect at bank of Nariin River in head of Nomrog. Three hundred Mongolian toads are estimated from a hectare at some sites of Mongol Daguur preserve (Munkhbaatar, 2004). Conservation of Mongolian amphibians and reptiles are being held as follow : Register and conserve in the Mongolian Red Book. There are 9 species of gerpetofauna have been registered in the Mongolian Red Book, and these are Siberian salamander, Pewzow’s toad, Japanese tree frog, Asiatic grass frog, Gobi naked-toed gecko, Sunwatcher toadhead agama, Stepperunner, Tatar sand boa and Slender racer. Amphibians and reptiles have been conserved at Special Protected Area Network. In 2008, 61 areas from Mongolian land, which are about 14% or 21.9 million hectares, have been protected as Protected Area.

정보보호 : SIFT 기반 카피-무브 위조 검출에 대한 타켓카운터-포렌식 기법

( Munkhbaatar Doyoddorj ),이경현 ( Kyung Hyune Rhee ) 한국정보처리학회 2014 정보처리학회논문지. 컴퓨터 및 통신시스템 Vol.3 No.5

Scale Invariant Feature Transform (SIFT)은 높은 매칭 능력과 회전이나 스케일 조정 시 안정성으로 인해 이미지 특징 매칭을 위해 많은응용에서 사용되어지고 있으며, 이러한 특성으로 인해 카피-무브 위조 검출을 위한 핵심 알고리즘으로 각광받고 있다. 하지만 SIFT 변환은 이미지 조작의 증거를 감출 수 있는 안티포렌식의 가능성이 높음에도 불구하고 이에 대한 연구는 거의 없으므로, 본 논문에서는 의미론적으로 허용될 수 있는 왜곡을 적용하여 SIFT 기반 카피-무브 위조 검출을 방해하기 위한 타켓 카운터-포렌식 기법을 제안한다. 제안 기법은 공격자가유사성 매칭 절차를 속일 수 있는 동시에 SIFT 키포인트의 변형을 통한 추적을 방해하여 이미지 조작의 증거를 숨길 수 있는 방안을 제공한다. 또한 제안 기법은 의미론적 제약 하에서 가공된 이미지와 원본 이미지 간의 높은 충실도를 유지하는 특성을 가진다. 한편, 다양한 조건의테스트 이미지에 대한 실험을 통해 제안 기법의 효율성을 확인하였다. The Scale Invariant Feature Transform (SIFT) has been widely used in a lot of applications for image feature matching. Such atransform allows us to strong matching ability, stability in rotation, and scaling with the variety of different scales. Recently, it has beenmade one of the most successful algorithms in the research areas of copy-move forgery detections. Though this transform is capable ofidentifying copy-move forgery, it does not widely address the possibility that counter-forensics operations may be designed and used tohide the evidence of image tampering. In this paper, we propose a targeted counter-forensics method for impeding SIFT-based copy-moveforgery detection by applying a semantically admissible distortion in the processing tool. The proposed method allows the attacker todelude a similarity matching process and conceal the traces left by a modification of SIFT keypoints, while maintaining a high fidelitybetween the processed images and original ones under the semantic constraints. The effiiency of the proposed method is supported byseveral experiments on the test images with various parameter settings.

A Numerical Study of Coaxially Gated Ballistic Carbon Nanotube Field-Effect Transistor

Munkhbaatar Nyam-Osor,Bolormaa Dalanbayar 한국멀티미디어학회 2011 한국멀티미디어학회 국제학술대회 Vol.2011 No.-

The developments of device structure and performance metrics of carbon nanotube Feld-effect transistors (CNTFETs) are rapidly advancing. Because of the capability of ballistic transport, CNTFETs are very attractive as high-speed transistors in highly integrated carbon nanotube (CNT) based circuits. Therefore, there is always a need for device numerical simulations. In this paper, we present results of numerical simulation of a coaxially-gated, ballistic CNTFET based on a semiclassical analytical theory, which is used to examine device performance limits. The results has been obtained by numerical methods using C++ programming.

잡음종속 Watershed 변환을 이용한 이미지 위조 검출

( Munkhbaatar Doyoddorj ),이경현 ( Kyung-hyune Rhee ) 한국정보처리학회 2013 한국정보처리학회 학술대회논문집 Vol.20 No.1

Noise is unwanted in high quality images, but it can aid image tampering. For example, noise can be intentionally added in image to conceal tampered regions or to create special visual effects. It may also be introduced unknowingly during camera imaging process, which makes the noise levels inconsistent in splicing images. In this paper, we present an image forgery detection method using a noise dependent watershed transformation. Image is segmented into objects for initial noise estimation by the watershed transformation, and different noise level in objects are estimated to obtain final decision result. Experimental results of the proposed method on natural images are presented.

Selection of stimulated Raman scattering signal by entangled photons

<P><B>Abstract</B></P> <P>We propose an excitation-probe measurement method utilizing entangled photon pulses. The excitation-probe signal is dominated by stimulated Raman scattering as well as two-photon absorption when the time delay between the excitation pulse and the probe pulse is shorter than the pulse duration. We demonstrate that the two-photon-absorption signal can be suppressed when the photons of the pulses are entangled. The stimulated Raman scattering signal can be composed of many peaks distributed over broad photon energies owing to the transitions between numerous quantum states in complex materials. We show that the desired peaks among the many peaks can be selected by controlling the thickness of the nonlinear crystal, the pump pulse center frequency, and the polarization of the excitation pulse and probe pulse.</P> <P><B>Highlights</B></P> <P> <UL> <LI> We propose an excitation-probe measurement method utilizing entangled photon pulses. </LI> <LI> The excitation-probe signal is dominated by nonlinear processes including stimulated Raman scattering. </LI> <LI> We demonstrate that the stimulated Raman scattering signal can be relatively enhanced by the entangled photons. </LI> <LI> The stimulated Raman scattering signal si composed of many peaks distributed over broad photon energies. </LI> <LI> Only the desired peaks among those many peaks can be selected by controlling the thickness of the nonlinear crystal. </LI> </UL> </P>

Privacy enhancing based a cancelable secure biometric template for ROI in face recognition

Munkhbaatar Doyoddorj,Kyung Hyune Rhee 한국멀티미디어학회 2010 한국멀티미디어학회 학술발표논문집 Vol.2010 No.1

One of the inherent properties of biometrics is the ability to use unique features for identification and verification of users. The usable biometric features in humans are limited in number and they must be kept secret. The biometrics are intrinsically associated with individuals and cannot be forgotten or shared with others. However, one of the most relevant vulnerabilities of biometrics is that once a biometric template is compromised, it cannot reissued, updated or destroyed. This paper proposes privacy concern for a self-exclusion scenario of face recognition with a simple biometric encryption scheme called helper data system. The privacy in a biometric verification system using combined with a source template coding (HD1) and hash function (HD2) which related to secure biometric templates with enhanced security.
