We report preliminary results from our analyses on the star-forming galaxies in the Herschel/SPIRE survey data over the AKARI/NEP-Wide Field. In this work, we utilize a combination of the SPIRE point source catalogue containing ~ 4,800 sources distributed over the wide (5.6 sq. deg) field and the spectroscopic redshift (zSPEC) data for 1790 selected targets obtained by MMT/Hectospec and WIYN/Hydra. Our analyses take advantages of multi-wavelengths photometric data (28 bands at most) covering from u* to $500{\mu}m$ band as well as continuous MIR wavelengths sampling by AKARI and WISE (4 to $25{\mu}m$). Various physical properties such as total infrared luminosity (LTIR), star formation rate (SFR), and luminosity functions (LFs) will be presented.

In the 1930s, The Architectural Association of Joseon run the 'Architectural Material Display' on the 2nd floor of the Japan Life Insurance Building in Hwanggumjeong(currently Euljiro street). The purpose of this place was to introduce new architectural materials to builders. And they issued a "建築資料型錄(Architectural Material Catalog)" and distributed it free of charge so that people in districts at long distances can make use of it. This catalog contains descriptions, photographs and drawings of various architectural materials that were common at the time, and the overseas branch address of the store is stated. The purpose of this research is to investigate the type and characteristics of architectural materials distributed in Northeast Asia around the 1930s, the region of sale, affiliated companies by closely analyzing the "建築資料型錄".

We have derived the luminosity function for subdwarfs on the basis of the proper motion data in LHS Catalogue, utilizing the reduced proper motion diagram for the selection of sub dwarfs and the hybrid method combining the mean absolute magnitude method and V/$V_m$ method to estimate the distance and density of subdwarfs. The luminosity function found here is almost flat, showing a very slow increase up to $M_V\;=\;9$ or $M_B\;=\;10$, and the overall halo density is larger than those derived by Schmidt (1975), Chiu (1980), Reid (1984), Lee (1985), and Dawson (1986), but smaller than that by Eggen (1983). Comparison with 1/100 of disk stellar luminosity function implies that no conclusive dip in the halo luminosity function is found.

The galaxy cluster is a good laboratory to test the cosmological model as well as the evolution of galaxies in the dense region. However the lack of wide and deep near-IR datasets has prevented to identify galaxy clusters at z>1. Here we merge a wide, deep near-IR datasets of UKIDSS DXS (J and K bands) and IMS (J band) with the CFHT Legacy Survey (CFHTLS) ugriz catalogue to detect galaxy clusters. We identify candidate galaxy clusters at z>0.8, where the near-IR dataset plays an important role to detect galaxies efficiently. The cluster mass is also estimated based on the cluster richness and the semi-analytical cosmological simulation.

In the late of 1990s, a super-high-rise residential started with the concept corresponding to a natural view, as the habitants' desire for spaciousness worked on an initiative factor. The appearance of the new style of residential form was encouraged and habitants' items desired were increased by the security of spaciousness for view. The purpose of this study is to understand spatial trans orientation through the plan type focusing the recent case study of super-high-rise and to interpretate spatial changes of residential space following it. For the case study, 20 apartments(or apartment complex) were selected from more than 25 storied super-high -rise located in Seoul and the metropolitan area. On the other hand, the objective facts about super-high-rise were cited in the results of the established studies and the selected cases were extracted from a catalogue and internet

Seismic risk management has two main technical aspects: to recommend the construction of high-performance buildings and other structures using earthquake-resistant designs or evaluate existing ones, and to prepare emergency plans using realistic seismic scenarios. An overview of seismic risk assessment methodologies in Croatia is provided with details regarding the components of the assessment procedures: hazard, vulnerability and exposure. For Croatia, hazard is presented with two maps and it is expressed in terms of the peak horizontal ground acceleration during an earthquake, with the return period of 95 or 475 years. A standard building typology catalogue for Croatia has not been prepared yet, but a database for the fourth largest city in Croatia is currently in its initial stage. Two methods for earthquake vulnerability assessment are applied and compared. The first is a relatively simple and fast analysis of potential seismic vulnerability proposed by Croatian researchers using damage index (DI) as a numerical value indicating the level of structural damage, while the second is the Macroseismic method.

최근 인터넷이 대중화되면서 웹을 통한 전자상거래가 점차 늘고 있다. 이에 따라 웹 기반전자상거래를 위한 문서교환의 표준화 연구는 여러 기업의 참여 하에 활발히 진행 중에 있으나 아직까지 전자상거래의 일부 절차는 체계화되어 있지 않다. 가장 활발한 전자상거래형태인 오픈마켓을 통한 중계판매에서 상품제조업체, 판매업체, 오픈마켓(중계판매업체) 간의 전자적 상품정보(e-Catalogue)교환은 거의 이루어지지 않고 있다. 이런 이유로 오픈마켓을 통한 전자상거래에서 상품을 판매하는 판매업체는 상품정보를 직접 수집하거나 가공하여 이를 오픈마켓에 등록한다. 실제로 이러한 상품정보 교환 과정에서 많은 인력과 시간이 소비된다. 본 논문은 이러한 문제점을 해결하기 위해 RFID ODS 기술과 ebXML 기술을 활용하여 상품제조업체와 판매업체, 판매업체와 오픈마켓 간의 상품정보를 공유할 수 있도록 하는 새로운 모델을 제안한다.

We reconstruct the underlying dark matter (DM) density distribution of the local universe within 20Mpc/h cubic box by using the galaxy position and peculiar velocity. About 1,000 subboxes in the Illustris-TNG cosmological simulation are used to train the relation between DM density distribution and galaxy properties by using UNet-like convolutional neural network (CNN). The estimated DM density distributions have a good agreement with their truth values in terms of pixel-to-pixel correlation, the probability distribution of DM density, and matter power spectrum. We apply the trained CNN architecture to the galaxy properties from the Cosmicflows-3 catalogue to reconstruct the DM density distribution of the local universe. The reconstructed DM density distribution can be used to understand the evolution and fate of our local environment.

The 『Hun-Gai-Tong-Xian-Tushuo 渾蓋通憲圖說』, which was an important astronomical book in East-Asia, was published by Li Zhi-zao (李之藻, 1565-1631) in 1607. This book was including the data of stars. We analyzed the data of stars recorded in 『Hun-Gai-Tong-Xian-Tushuo 渾蓋通憲圖說』. Based on historical background, we assumed that the data of stars recorded in 『Hun-Gai-Tong-Xian-Tushuo 渾蓋通憲圖說』 likely referenced knowledge from the ancient Arab/Islam culture. In conclusion, we assume a correlation with the star catalogue included in 『Almagest』 by Ptolemaios. Therefore, we think that this star's data will become important data for comparison with the star catalogues published in Arabic/Islam.
