        Our professors and teachers have been cooperated with professors and researchers of National Sciences Museum of Korea for the project of “Biodiversity of Mongolian” since 2012. This project is to study for Mongolian biodiversity by Mongolian and Korean scientists and to support advanced training for our professionals, to increase capabilities and training new methodologies for students and to publish articles from the conducted research. Our researches conducted following areas such as in Ikh Nart Nature reserve area in 2013, Khan Khentii strictly protected area in 2014, our university’s Shatan research camp in 2014, and Kherlen Toonot Nature reserve area in 2015. From these studies, we published articles of “Biodiversity of Ikh Nart Nature reserve” and “Biodiversity of Shatan area” in Korean journals. Our teachers anticipated for publishing guidebook “Methods to preparing natural taxidermy and herbarium” in Mongolian prepared by Korean scientists to useful for students in laboratory and field. Teachers are visited in National science museum of Korea, such as Mr. J.Ariunbold studied in 2013 and Dr. M.Munkhbaatar visited for 14-30 days to develop samples collected from field research. Our teaching assistant G.Onolragchaa is enrolled as doctoral student for Chunnam University in 2015 according to this project grant. Also Mr. P.Erdenetushig and one student are planning to visit in October for developing collected samples. In 2015, School of Mathematics and Natural Sciences is willing to establish “Mongolian and Korean monitoring center”, it’s in compromise of both side, and Mongolian National University of education is prepared a room for this center. Коrean colleague provided USD 10.000 worth of new equipment such as electric motor, boryoscope, tent trap, Sherman trap, aquatic net, sweep net, glass vials and bottles for research and teaching of MNUE. Framework of Mongolian-Korean cooperative research project “Biodiversity of Mongolia” was held a conference topic on “Biological resource management and remote sensing survey” in Ulaanbaatar 2014 and 2015. Our scientists are planning future collaboration with scientists of Korean ocean research institute, Ornithological Society of Korea, Korea Institute of Environmental Ecology.

        We have been performing daily VLBI monitoring of the ux density of Sagittarius (Sgr) A* at 22 GHz from February 2013 to August 2014 using a sub-array of the Japanese VLBI Network (JVN). The purpose of this monitoring is to explore the ux density variability at daily time resolution for a period longer than one year with the G2 cloud approaching. The ux density of Sgr A* is basically stable during the observational period, though there are some small variations. The average and scattering range are consistent with the previously observed values. We have observed no strong are of Sgr A* although it is near the expected peri-center passing.

        Polarbear is a ground-based experiment located in the Atacama desert of northern Chile. The experiment is designed to measure the Cosmic Microwave Background B-mode polarization at several arcminute resolution. The CMB B-mode polarization on degree angular scales is a unique signature of primordial gravitational waves from cosmic in ation and B-mode signal on sub-degree scales is induced by the gravitational lensing from large-scale structure. Science observations began in early 2012 with an array of 1,274 polarization sensitive antenna-couple Transition Edge Sensor (TES) bolometers at 150 GHz. We published the first CMB-only measurement of the B-mode polarization on sub-degree scales induced by gravitational lensing in December 2013 followed by the first measurement of the B-mode power spectrum on those scales in March 2014. In this proceedings, we review the physics of CMB B-modes and then describe the Polarbear experiment, observations, and recent results.

        Galaxies can be "pre-processed" in the low-density outskirts by ambient medium in the filaments or tidal interactions with other galaxies while falling into the cluster. In order to probe how early on and by which mechanisms galaxies can be affected before they enter high-density cluster environments, we are carry- ing out an atomic hydrogen (H i) imaging study of a sample of galaxies selected from three filamentary structures around the Virgo cluster. Our sample consists of 14 late-type galaxies, which are potentially interacting with their surroundings. The Hi observations have been done using the Westerbork Synthesis Radio Telescope, the Giant Metrewave Radio Telescope, and the Jansky Very Large Array with column density sensitivity of ≈ 3-5 X 1019 cm-2 in 3σ per channel, which is low enough to detect faint Hi features in the outer disks of galaxies. In this work, we present the Hi data of two galaxies that were observed with GMRT. We examine the Hi morphology and kinematics to find the evidence for gas-gas and/or tidal interactions, and discuss which mechanism(s) could be responsible for pre-processing in these cases.

        We use ALLWISE data release W1- and W2-band epoch photometry collected by the Wide-Field Infrared Survey Explorer (WISE) to determine slopes of the period-luminosity relations for RR Lyrae stars in 15 globular clusters in the corresponding bands. We further combine these results with V- and K-band photometry of Galactic field RR Lyrae stars to determine the metallicity slopes of the log PF - [Fe/H]-MK, log PF - [Fe/H]-MW1, and log PF - [Fe/H]- MW2 period-metallicity-luminosity relations. We infer the zero points of these relations and determine the kinematical parameters of thick-disk and halo RR Lyraes via statistical parallax, and estimate the RR Lyrae-based distances to 18 Local-Group galaxies including the center of the Milky Way.

        We report results of the measurement of the trigonometric parallax of an H2O maser source in IRAS 22555+6213 with the VLBI Exploration of Radio Astrometry (VERA). The annual parallax was determined to be 0.2780.019 mas, corresponding to a distance of 3.66+0:30 -0:26 kpc. Our results con rm that IRAS 22555+6213 is located in the Perseus arm. We computed the peculiar motion of IRAS 22555+6213 to be (Usrc; Vsrc;Wsrc) = (0 ± 1,-32 ± 1, 9 ± 1) km s􀀀1, where Usrc, Vsrc, and Wsrc are directed toward the Galactic center, in the direction of Galactic rotation and toward the Galactic north pole, respectively. IRAS 22555+6213, NGC7538 and Cepheus A lie along the same line of sight, and are within 2 on the sky. Their parallax distances, with which we derived their absolute position in the Milky Way, show that IRAS 22555+6213 and NGC7538 are associated with the Perseus arm, while Cepheus A is located in the Local arm. We compared the kinematic distances of IRAS 22555+6213 derived with at and non- at rota- tion curve with its parallax distance and found the kinematic distance derived from the non- at rotation assumption (—32 km s-1 lag) to be consistent with the parallax distance.

        Research on new product development has emphasized the importance of integrating customers, employees, and suppliers in an organization’s innovation processes. While several studies evaluate respective participatory processes, there is, surprisingly, no consensus on which dimension participation quality consists of, and how to measure them consistently. The present study contributes to the literature by identifying the dimensions of participation quality and by constructing a participation quality scale that includes six dimensions, namely (1) project-related resources, (2) early involvement, (3) degree of influence, (4) transparency of processes, (5) incentive mechanisms, and (6) voluntariness of participation. Furthermore, a 24-item measure of participation quality is developed using a mixed-method design. Results of our study show that the developed measure impacts important innovation-related outcomes such as innovation performance, acceptance of the innovation, and intention to participate in future innovation projects. Given that the six identified dimensions of participation quality differentially affect these outcomes, the scale provides the opportunity to better design participatory innovation projects, and thus helps managers to integrate stakeholders more successfully in these projects.

        In this study, synthetic viscose rayon fabric has been used for preparing activated carbon fabric (ACF), impregnated with different concentrations of H3PO4. The effect of H3PO4 im-pregnation on the weight yield, surface area, pore volume, chemical composition and mor-phology of ACF were studied. Experimental results revealed that both Brunauer-Emmett-Teller surface area and micropore volume increased with increasing H3PO4 concentration; however, the weight yield and microporosity (%) decreased. It was observed that samples impregnated at 70°C (AC-70) give higher yield and higher microporosity as compared to 30°C (AC-30). The average pore size of the ACF also gradually increases from 18.2 to 19 and 16.7 to 20.4 Å for 30°C and 70°C, respectively. The pore size distribution of ACF was also studied. It is also concluded that the finalACF strength is dependent on the concentra-tion of impregnant.
