This paper is written to clarify the specific details of the Sabu-Songyu­Mongnok(사부송유목록). which is a reading list for recitation and appreciation of Chinese classics edited by Hong Suk-Chu(1774-1842) when he was 56 years old for the stimulation of his younger brother Hyun-Ju (1793-1865)'s reading life. In this study the catalogue's title interpretation. the time of the editing, the motive for the editing and the analysis of the contents are revealed as what they actually are. The main details are as followings. There is no date written on the Sabu-Songyu-Mongnok but the writer estimate it to be around 1829. After Hong Suk-Chu recognized the fact that although his younger brother Hyun-Ju was interested in reading but felt that he was a little too old to begin to read all the books of the whole classes. he selected the classic works from whole subjects, i.e. history, philosophy and anthology, that he thought which would best represent each subject. From these selected works he then picked out the most important chapters or parts of the works. Another motivation of the editing was for the stimulation of the reading life for Hong Suk-chu himself and for people like himself who were getting old and losing their vitality. The Sabu-Songyu-Mongnok consists of four categories. i.e. classics category, history category, philosophy category and anthology category, and in the catalogue, 26 different works are entered. The classics category has ten, the history category has six, the philosophy category has six and the anthology category has four. Each of the works are entered under the title of the book, and hen the chapter heading. The Sabu-Songyu-Mongnok was edited 19 years later than Hong-ssi toksorok(홍씨독서록) or an Annotated Bibliography of Korean and Chinese Books. Comparing each category of the catalogue with the Hong-ssi toksorok, the writer could catch the following characteristics. 1. Although there was no indication of the class heading, the sequence of the arrangement of the entries in the classics categories was the same as the sequence of the classes in the Hong-ssi toksorok. 2. The Zuo-shi Chun-qiu-zhuan(좌씨춘추전) is recorded in the class of Chunqiu of the classics category in the Hong-ssi toksorok, but in the Sabu-Songyu­Mongnok, it belongs to the history category. 3. In the philosophy category of the catalogue, Chuangtzu(장자) writings are included because it is so well written. 4. Unlike the categories of classics, history and anthology, the philosophy category is recorded under the author's name. This is fascinating because it unites with the conventional cataloguing practice of the west. 5. In the anthology category, the writings with the best styles from the Chuci(초사) or the poems of Chou, Wen-xuan(문선), wen-yuan-ying-hua(문여영화) are selected and classified into four parts: (1) poems, (2) proses of Han, Wei and Pre-Qin dynasties. (3) Si-liu-pian-li-wen(사육병려문), (4) classic style of writings of Tang and Song dynasties (당송고문). 6. There was an unusually large number of Han Yu's writings selected from the great eight poets of Tang and Song dynasty writings. (20 categories out of $43: 47\%)$ After comparing the entries of the Sabu-Songyu-Mongnok, it can be concluded that all the entries were also included in the Hong-ssi tokrorok. The fact that the sequence of the entries in the classics category and that the literary works were sequenced under the same subject by the year of editing or writing like as the Hong-ssi toksorok Also it is unusual that there was not even one literary work of a Korean in the catalogue. Anyhow this catalogue is the first recitation catalogue in our country that was edited for the people in the prime of life as well as for old people and is the only one existing today.

The historical development of books examination with utilizing science become inevitable to the machanization of library catalogues. With the advance of times, like this, a new- development of $Indention('||'&'||'$ : Kisun) must be sought for which is a kind of descriptive catalogues being used now. This paper is scheduled to grasp problems in the course of using and logical grounds of Indention which hal-e been used disordering. It must be considered that four kinds of Icdention settlement is suitable to the features of Korean letters. 1) TI-e must consider the features of Korean Language and Oriental Language writing(Japan, China). There must be a establishment of floating $Indention('||'&'||'E$ : Kisun), which are suitable for the writting style or hand writting man on the point of most of Koreans are depend upon hand witting, then books catalogues like western language, not left edge of the cards of the $Indention(B$ : Kisun) establishing, from edge to Call Number, from the last of the Call Number to First Indention(%-Bl63). First Indention(%-%%) to a space of Second $indention($\ulcorner^%)$ must be established and then, every catalogue and Indentions are distinguished surely. 2) \Then we consider the developing catalogue making in the future. It is important to establish a fixed $Indention('||'&'||'$ : Kisun) for machinization of typewriter(Korean, Mimeographing) and computer, etc ... not "Cm" unit but "Space" unit, and consider oriental letter, ne make more surplus space as a Indention, we can give anadaptablity of using machines. 3) Considering typography printing and type-setting printing by printing type, we must fit the $Indention(\ulcorner'||'&'||'$ : Kisun) as a "Cm" unit, and there must be a re-adjustment of $Indention(g$$ : Kisun) which considered the complexity of Call Number by a mass of collecting books like this, the establishment of Indention(E'||'&'||'j!: Kisun). We must not use a uilified one as a concrete conception by "Space" or "Cm" unit which has been used now but re-adjusted adaptably which can be fited as a method of making of catalogues. 4) The name of $Indcntion(J, S$ : Kisun) has becll called 7;arious methods until now, but English Indention which has been used without any concrete mexirig must be used as a ours fitable as a our mind. The above mentioned is presented as a Indention and examinational l~letilods by myself style, I wants these r i l l be helpful to the future developments of the machanization of Indention $(sf:$ Ki sun). Concrete studies must be continued in the future for development of $Indention(zj:$ : Kisun). : Kisun).

We present a pipeline to estimate baryonic properties of a galaxy inside a dark matter (DM) halo in DM-only simulations using a machine trained on high-resolution hydrodynamic simulations. As an example, we use the IllustrisTNG hydrodynamic simulation of a (75 h^-1 Mpc)³ volume to train our machine to predict e.g., stellar mass and star formation rate in a galaxy-sized halo based purely on its DM content. An extremely randomized tree (ERT) algorithm is used together with multiple novel improvements we introduce here such as a refined error function in machine training and two-stage learning. Aided by these improvements, our model demonstrates a significantly increased accuracy in predicting baryonic properties compared to prior attempts --- in other words, the machine better mimics IllustrisTNG's galaxy-halo correlation. By applying our machine to the MultiDark-Planck DM-only simulation of a large (1 h^-1 Gpc)³ volume, we then validate the pipeline that rapidly generates a galaxy catalogue from a DM halo catalogue using the correlations the machine found in IllustrisTNG. We also compare our galaxy catalogue with the ones produced by popular semi-analytic models (SAMs). Our so-called machine-assisted semi-simulation model (MSSM) is shown to be largely compatible with SAMs, and may become a promising method to transplant the baryon physics of galaxy-scale hydrodynamic calculations onto a larger-volume DM-only run. We discuss the benefits that machine-based approaches like this entail, as well as suggestions to raise the scientific potential of such approaches.

To understand the connection between active galactic nuclei (AGNs) and star formation, we investigated the relation between AGN bolometric and far-infrared (FIR) luminosities, using type-2 AGNs. By matching type-2 AGNs at z < 0.3 selected from the SDSS based on the emission-line diagnostics, against the AKARI/FIS All-Sky Survey Catalogue and the COSMOS PEP (PACS Evolutionary Probe) Survey Catalogue, we obtained a sample of 729 type-2 AGNs detected in the AKARI survey ($90{\mu}m$) and 17 ones detected in the PEP survey ($100{\mu}m$). For AGN bolometric luminosities, we adopted an estimate based on the [OIII] and [OI] line luminosities. We confirmed that there is a correlation between the AGN bolometric and FIR luminosities with a large scatter, which is consistent with previous studies. However, we claim that this correlation suffers from various artificial effects, e.g., FIR detection limits, survey volumes, and so on. We will discuss the limitations of studying the connection between AGN and star formation using currently available facilities.

Although features, core element of marine GIS in many application, are same things users have difficulty in using them on account of varying according to method of classification. Accordingly feature cataloguing in accordance with the standard is the trend of the modem world. In this article we have became familiar with ISO 19110 - Methodology for Feature Cataloguing, we was able to discuss element and definition of features for the purpose of Marine GIS's activation. Through the result of study, we presented the methodology of Marine GIS feature cataloguing.

We have employed SNANA supernova analysis package to make YONSEI Supernova Catalogue 1, which contains distance modulus, light-curve shape parameters, and color or extinction values of each supernova. This database is used to study the dependence of Type Ia supernovae (SNe Ia) luminosities on the host-galaxy morphologies. The redshift range of this catalogue is 0.010 < z < 1.555, and we use three light-curve fitters: SALT2, MLCS2k2 (Rv = 3.1), and MLCS2k2 (Rv = 1.7). We find a systematic difference in the Hubble residual (HR) of $0.1{\pm}0.031$ mag between E-S0 and Scd/Sd/Irr host-galaxies, and of $0.16{\pm}0.044$ mag between passive and star-burst host-galaxies. This difference is significant over the $3{\sigma}$ level. Considering the significant difference in the mean age of stellar population between these morphological types, the difference in the HR reported here suggests that the evolution effect of SNe Ia luminosity should be considered in the cosmological application of SNe Ia data.

The purpose of this research is to investigate economic factors that determine characteristics of B2B e-Marketplaces. From a previous research work, we classify B2B e-Marketplaces into four forms: MRO Hubs, Catalogue Hubs, Yield Managers, and Exchanges. This classification is based upon "What businesses buy" and "How businesses buy." In an attempt to identify economic factors that determine e-Marketplace forms, we employ three economic factors: buyer/seller relationships, features of products traded, and characteristics of industries or markets. Through extensive literature reviews, we have selected six variables which can be used to explain reasons for different e-Marketplace forms: asset specificity and information asymmetry for the buyer/seller relationship, standardization and price variability for the product features, entry barrier and market volatility for the market characteristics. This research conducts six in-depth case studies to explain that "Why different forms of e-Marketplace emerge?" The research framework intends to provide link between e-Marketplace forms and six economic variables. Six case studies are based on interviews with CEO or team managers of e-Marketplace firms. This study has found six economic variables, explaining well reasons for different e-Marketplace forms. Research findings are summarized as propositions so that survey-type research can be conducted with a large number of samples in the future.
