공작 기계의 실시간 폐회로 컴퓨터 수치 제어 시스템
No full text학위논문 (석사) - 한국과학기술원 : 전기 및 전자공학과, 1978, [ [v], 98, [2] p. ]The computer numerical control(CNC) system that has a direct numerical control metal processing facility is implemented by using a minicomputer(Nova 1200) and peripheral equipement. As the control scheme, two types of closed loop contouring controls are considered. One is a closed loop scheme which after each step checks the machine status to determine if the path is correct. The error occured is compensated so as to minimize the future errors. The other closed loop scheme is to allow the entire table movement to be complete before the check routine determines if the table is at its final location. This is used a point-to-point operation where the path is immaterial. The conversational computer language BASIC has been expanded to include various machine tool performance commands which are applied to manufacturing equipment from a standard input terminal. Also there are commands that force a machine tool to move to a desired position, that specify a delay or dwell of time or that generate a display of the programed part. In order to show the possibility of the adaptive control system, a simple case of the adaptive control system is simulated. As actuators, a stepping motor and hydrauric servo system are used. Analysis of the actuators is given in the thesis.한국과학기술원 : 전기 및 전자공학과
Three essays on the role of bank lending
Get PDFThesis(Doctoral) --KDI School:Ph.D in Public Policy,2016This paper analyzes the dynamic effects of credit supply on economic growth and the shortand long-term relationship between house prices and income inequality in 18 OECD countries. It was found that increased income inequality expands credit supply in the short term but reduces credit supply in the long term. Increasing house prices contribute positively to greater credit supply and drive economic growth. However, when house prices are higher than long-run equilibrium levels, credit supply can negatively contribute to economic growth. Finally, income inequality has a negative influence on the effect of credit supply on economic growth when it is at a higher phase than the long-run equilibrium level. These results suggest that when an excessive increase in house prices and income inequality occurs, it is necessary to consider the possibility that increasing credit supply may not boost economic growth is necessary.
This paper examines the effect of bank financing on corporate value through the study of KOSPI listed companies from 2003 to 2013. It use the bank loan ratio as a proxy variable for the level of bank monitoring. The analysis results showed that a higher bank loan ratio negatively affected firm value for financially troubled companies with an interest coverage ratio below 1. And for companies with a centralized ownership structure where controlling shareholders have 35% or more shares, a higher bank loan ratio positively affected firm value. This paper also confirmed that bank monitoring effects can differ between firms with high default risk and those with concentrated ownership structure through an event study analysis regarding the impact of the announcement of a unique Korean bank monitoring system of MDG designation on corporate stock price. Negative effects were observed in cases of firms with a high default risk, whereas positive ones in case of firms with concentrated ownership structure. These results of this analysis are generally the same as those which use a bank loan ratio variable.
Korean Savings banks that expanded the number of high-risk loans experienced huge defaults after the 2008 global financial crisis. We consider the prompt corrective action (PCA) to analyze factors that drive savings banks to failure given that an order for PCA by a supervisory authority normally leads to defaults. We conduct discrete choice models to estimate the probability of PCA, using 2005 to 2011 data on 103 Korean savings banks. We find that the post-examination actions taken by supervisory authorities and a rapid increase in loans increase the possibility of PCA. These results suggest that depositors and the market can reduce the costs incurred from defaults by identifying information that predicts PCA.Chapter 1: What Do House Prices and Income Inequality Tell About Finance and Growth?

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Factors Driving the Prompt Corrective Action of Supervisory Authorities: Evidence from Korea's Savings Banks

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
