  • As computational resolution of modern cosmological simulations reach ever so close to resolve individual star-forming clumps in a galaxy, a need for "resolution-appropriate" physics for a galaxy-scale simulation has never been greater. To this end, we introduce a self-consistent numerical framework that includes explicit treatments of feedback from star-forming molecular clouds and massive black holes. We perform a state-of-the-art cosmological simulation of a quasar-host galaxy at z~7.5, and demonstrate that previously undiscussed types of interplay between galactic components may hold important clues about the growth and impact of quasar-host galaxies.

  • The followings are the landscape preference aspects from the 816 landscapes(景, Kyung), which comprise the 78 modern Palkyungs, presented by the 78 local governments in Korea. First, the natural environment elements selected as Kyung(景), which are topographical landscapes, mostly consist of mountain elements such as mountains, terrace(臺), rocks and stones and water elements classified as rivers, oceans, and lakes. Natural elements also include old-growth and giant trees such as pines, ginkgos, Japanese cornels and fringe trees, tree-lined streets and forests, and plant elements such as azaleas, rhododendrons, lotuses, reeds, and silver grasses which provide seasonal landscapes. Second, more than half of Kyung, selected as human environment elements, are historical and cultural heritages such as graveyards, mountain fortresses, town fortresses, traditional villages, pavilion in villas, and temples. And it is followed by leisure tourism facilities such as traditional markets, exhibition halls, theme parks, beaches, and food streets, green-based structures such as trails, plazas, parks, and botanical gardens, and industrial heritages such as ranches, abandoned coal mines, stations, ports and bridges. Third, modern Palkyungs include objects not related to the views such as local representative facilities, regional products, and festivals. Fourth, although most of the modern Palkyungs consist of eight, some include 20, 38, or 100 in order to increase the number of objects of public relations. Fifth, a certain local government makes two modern Palkyungs with different subjects by introducing traditional Palkyung and modern Palkyung altogether. In this case, it presents several modern Palkyungs like by selecting Palkyungs in a limited area. Furthermore, one Palkyung includes numerous place names at a time in some cases. Sixth, Sosangjeonhyeong(瀟湘典型)-style modern Palkyung uses 'NakAn(落雁)' as the name of Kyung. Sosangyusahyeong(瀟湘類似型)-style modern Palkyung expresses 'Hyojong(曉鐘)' and landscape of glow of the setting sun, sunset, night view, dawn, sunrise and depicts cloud, sunset, moon, and snow. There are many Myeongsocheheomhyeong(名所體驗型)-style Palkyungs exhibiting the behavior of tourism and Myeongseunghyeong(名勝型)-style Palkyungs raising the awareness only by the names of the places. Seventh, modern Palkyung's naming styles are diverse, such as using only four letters instead of specifying Kyungmul(景物) or Kyungsaek(景色) in combination with Chinese characters or adding modifiers specializing in places.

  • The Seoul Woods Design Competition in 2003 was one of the most remarkable events within the field of landscape architecture in Korea since the Yeo-Ui Do Square Park Design Competition in the mid 1990s. This study examines the overall procedure, evaluations and competition guidelines for the Seoul Forest Park Design Competition and identifies the implications and issues related to Korean landscape architecture. In addition this study analyzes the design concepts, strategies and spatial composition, and programs of five selected design worts including the best awarded work. This study also examines key features and issues from the five selected design works. Finally, this study examines a new trend of landscape design in Korea, which can be observed at the Seoul Forest Park Design Competition. In this study, it is argued that the Seoul Forest Park Design Competition had significant implications for landscape architecture in Korea. Firstly, the Seoul Forest Park Design Competition was the greatest project in Korea in terms of its size. Therefore, it shows us an enhanced status of Korean landscape architecture. Secondly, the Seoul Forest Park Design Competition provided a good opportunity to redefine the concept of 'park' in Korean modern society. Thirdly, through the Seoul Forest Park Design Competition, we can observe a dramatic change and developments in Korean landscape design since the 1990s, as well as the present status of landscape design competitions in Korea. And this study identifies an emphasis of a program in design, an evolution in ecological approach an diminishment in concern of Korean tradition, and a change in design methods and media, which are some aspects of Korean contemporary landscape design observed at the Seoul Forest Park Design Competition.

  • This study investigates coping strategies of overweight or underweight males in Korea. For this purpose, the authors identify types of stress related to weight management. A qualitative method was utilized to collect the data related to successful weight management experiences of males aged 20-37 years. Data were analyzed based on a motivation theory of coping, which suggests coping strategy elements. The results of this study identified the stress related to weight: dissatisfaction with appearance, others' disapproval of appearance, health problems, weaker athletic ability, negative self-perception, passiveness about appearance, lower romantic attractiveness, others' disapproval of lower romantic attractiveness, weakened task execution capability, and negative stereo-types about task execution capability. In addition, six coping strategies were suggested: improved appearance, improved physical function, improved positive self-perception, more choices to improve appearance, enhanced romantic relationship, and enhanced job performance. This study shows that weight problems in modern society are diverse and complex. Therefore a man who has abnormal weight needs to clarify his stress first and then proposes strategies that are appropriate for each type of stress.

  • Galaxy clusters, the largest gravitationally bound systems, are an important means to place constraints on cosmological models. Moreover, they are excellent places to test galaxy evolution models in connection to the environments. To this day, massive clusters have been found unexpectedly at high redshfit (Kang & Im 2009, Durret et al. 2011, Tashikawa et al. 2012), and evolution of galaxies in cluster has not been fully understood. Finding galaxy cluster candidates at z > 1 in wide, deep imaging survey data will enable us to solve such issues of modern extragalactic astronomy. We report new candidates of galaxy clusters in the wide and deep survey fields, European Large Area ISO Survey North1(ELAIS-N1) and North2(ELAIS-N2) fields, covering sky area of $8.75deg^2$ and $4.85deg^2$ each. We also suggest a new useful colour-colour selection technique to separate 1 < z < 2 galaxies from low-z galaxies by combining multi-wavelength data from the UKIRT Infrared Deep Sky Survey Deep Extragalactic Survey (UKIDSS DXS, JK bands), Spitzer Wise-area InfraRed Extragalactic survey (SWIRE, Optical-Infrared bands), Canada France Hawaii Telescope (CFHT, z band) and Infrared Medium-deep Survey(IMS, J band).

  • Though anatomical and histological investigations on the novel threadlike and corpuscular structures, Bonghan duct(BHD) and Bonghan corpuscles(BHC) of internal organs of rats and rabbits were extensively studied. In this article we introduce the refined method to observe the BHD and BHC on the internal organs of mice. This development is needed because immunohistochemical analysis and other modern biological techniques were mostly applicable only to mice but not to rats and rabbits. We made uses of grazing effect of light as well as discriminating technique of BHD/C from fibrin and take the novel structures, BHD/C on mouse internal organ. The specimens taken were examined by hematoxyline and eosin(H & E) and revealed as novel structures. Our method described herein to take BHD/C characterization of mouse, especially for stem cell related researches.

  • Galaxy clusters, the largest gravitationally bound systems, are an important means to place constraints on cosmological models. Moreover, they are excellent places to test galaxy evolution models in connection to the environments. To this day, massive clusters have been found unexpectedly(Kang & Im 2009, Durret et al. 2011, Tashikawa et al. 2012) and evolution of galaxies in cluster have been still controversial (Elbaz et al. 2007, Cooper et al. 2008, Tran et al. 2009). Finding galaxy cluster candidates in a wide, deep imaging survey data will enable us to solve the such issues of modern extragalactic astronomy. We have used multi-wavelength data from the UKIRT Infrared Deep Sky Survey Deep Extragalactic Survey (UKIDSS DXS/J and K bands), Spitzer Wise-area InfraRed Extragalactic survey (SWIRE/two mid-infrared bands), the Panoramic Survey Telescope and Rapid Response System (PAN-STARRS/ g, r, i, z, y bands) and Infrared Medium-deep Survey(IMS/J band). We report new candidates of galaxy clusters and properties of their member galaxies in one of the wide and deep survey fields ELAIS-N1, European Large Area ISO Survey North1, covering sky area of $8.75deg^2$.

  • In the TV broadcasting, movie production and business the transportation of video between creators (programmers, studios) and distributors (broadcast and cable networks, cable and satellites companies) is still a mix of File Transfer Protocol (FTP), physical delivery, and expensive multicast satellite. Cloud-based file sync-and-share providers like Dropbox and box are playing an increasing role, but the industry's unique demands for speed and multicasting have fueled the growth of IP Video transport. This paper gives a solid grasp of the major elements of IP video technology, including content preparation, system architecture alternatives and network performance management.

  • We investigated the elementary students' epistemological views on the nature of scientific measurement. The Views About Scientific Measurement (Ibrahim, 2005) was administered to 117 sixth graders. The analyses of the results indicated that there was an inconsistency in their epistemological views depending on the contexts of the measurement. They also had some difficulties in understanding a distribution of the data, which is needed to understand the necessity of repeating measurements, choosing a best representative value, and comparing data sets. They were found to have some naive views on scientific measurement which influenced negatively for fostering modern epistemological views on the nature of scientific measurement. The results suggest that the nature of scientific measurement should be emphasized explicitly in the national curriculum, and an effective method which improves elementary students' epistemological views on the nature of scientific measurement also be developed.
