This study aims to investigate strategies for attracting consumers in Urban Entertainment Centers and understand the relationship between user satisfaction and intention of revisiting. To accomplish this, the strategic attraction factors were set as functional, experiential, episodic, and semantic. The relationships between these factors and revisiting intentions were studied experimentally. The result of the study can be summarized to 3 points. First, the 4 strategic factors that were selected all had a significant influence on revisiting intention. Therefore the more these factors have an influence, the higher the satisfaction and revisiting intentions. Secondly, out of the attraction factors the one with the biggest influence to customer satisfaction turned out to be 'functional factors' which is related to convenience, accessibility and availability. The factor that had the biggest influence on revisiting intentions turned out to be 'semantic factors' which is related to events, unusualness and temporality. Through this result we can see that to enhance satisfaction 'functional factors' should be considered first and to increase revisiting intentions 'episodic factors' should be considered first. Thirdly, it could be assumed that satisfaction of the visitors could boost intentions of revisiting.

The instability associated with the gas-liquid interface that builds up when compressible gas jet in injected into the liquid environment is theoretically analyzed. Classical flow theory predicted the transition from bubbling jet into continuous gas jet occurred at transonic speed. In the present study, it was demonstrated that similar result can be achieved from viscous potential flow theory. Surface tension and viscous force in liquid tend to stabilize the gas-liquid interface. And in non-axisymmetric mode, the transition occurs at different velocity regime.

Positioning information of workers is important for safety management at construction sites. Among the various indoor positioning technologies, geomagnetic fields-based technology is more economical and has less error than other technologies. However, there is a problem that the installation and dismantling of materials such as formwork at construction sites can cause degradation in positioning performance. Therefore, in this study, the distortion of the geomagnetic field near euro-form was quantitatively measured and the application method of geomagnetic field-based indoor positioning technology on formwork stage was presented. The results showed that the distortion occurred within 10cm of the wall and column form, but positioning accuracy could be affected up to 60cm from the form due to the characteristic of geomagnetic field-collecting technology. Therefore, applying this technology to the formwork stage requires complementary measures, such as using other positioning techniques up to 60 cm near the formwork, or excluding distorted area when positioning. It is expected that this study can contribute to the efficient safety management of workers by suggesting ways to prevent an increase in positioning error when applying geomagnetic field sequence-based indoor positioning technology during the formwork stage.

사회생태주의적 관점에서의 한국 복지국가담론 비판과 대안

김형준(Kim Hyungjun),한동우(Han Dongwoo) 비판과 대안을 위한 사회복지학회 2012 비판사회정책 Vol.- No.36

이 글의 목적은 사회생태주의적 관점으로 최근 한국 사회의 복지국가 담론들을 비판하고, 이러한 복지국가담론에 사회생태주의적 가치가 포함되어야 함을 주장하는 데 있다. 이 글에서는 최근 제기되고 있는 ‘정의로운 복지국가론’과 ‘역동적 복지국가론’ 그리고 ‘삼차원 복지국가론’을 비판의 대상으로 삼고 있으며, 분석틀로는 사회생태 주의의 주요 가치인 ‘탈지배’, ‘참여’ 그리고 ‘연대’를 활용하였다. 분석결과, 정의로운 복지국가론과 역동적 복지국가론은 복지제공 주체로서 국가의 관료제적 개입을 상대적으로 과도하게 설정하는 한편, 시민사회의 중요성과 역할을 적극적으로 다루고 있지 않는 것으로 판단되며, 시장임금 중심의 노동-복지 연계를 강조하는 반면, 기본소득 보장 등 노동의 탈상품화 혹은 탈시장화에 대한 의지가 확연하게 드러나고 있지 않은 것으로 판단된다. 또한 복지국가 체제 구성에 있어, 이 두 담론은 참여와 연대 수준의 관점에서, 상층과 제도 정치권 중심의 참여와 연대를 강조하는 한편, 지역사회 수준에서의 시민들의 직접적 참여와 연대 형성에 대한 고려는 부족한 것으로 나타나는 등 사회생태주의적 관점에선 다소 부정적으로 분석되었다. 이에 비해 ‘삼차원 복지국가론’은 복지제공 주체로 지역공동체와 시민사회에 주목하고 있으며, 지역에서의 주민 참여와 연대를 강조하고 있다는 점에서 현 단계에선 가장 생태적 가치를 포함하고 있는 담론으로 분석되었다. 사회생태주의는 서구의 복지국가가 경제성장과 임금소득, 그리고 관료제에 과도하게 의존하고 있다는 점을 비판하며, 이른바 복지국가 황금기를 지탱했던 경제성장과 이에 따른 측적 시스템의 지속가능성을 의심하고 있기 때문에, 여전히 이에 의존하고 있는 복지국가의 미래도 불투명하다고 경고하고 있다. 사회생태주의는 사회복지에 지속가능성이라는 개념을 제시해 주고 있다. 따라서 사회복지와 생태주의의 결합은 매우 중요한 시도이며 이것은 복지국가 담론은 물론, 사회복지의 새로운 이론화 작업에도 기여할 수 있을 것이다. The purpose of this article is to recommend that we should include some value of social ecology when discussing the welfare state in Korea. In this paper, we select three welfare discourses, ‘the just welfare state’, ‘the dynamic welfare state’, and ‘the three-dimensional welfare state’, as subjects for critical analysis, and utilize main concepts of social ecology, ‘de-domination’, ‘participation’ and ‘solidarity’, as a framework for analysis. The results are as follows; in view of de-domination, we could find out that ‘the just welfare state’ and ‘the dynamic welfare state’ tend to heavily depend on bureaucratic approach of the state as a welfare provider, while underestimating importance and roles of civil societies. They both also place an emphasis on workfare for wage earnings. In view of participation and solidarity, these two discourses focus on upper-level and political level, whereas little considering citizens’ direct participation and co-operation in the community-level. But, ‘the three-dimensional welfare discourse’ focuses on local communities and civil societies as a welfare provider and residents’ participation and solidarity in local areas. So far, this discourse has included some ecological values the most among three discourses. Social ecology has criticized the welfare state owing to its heavy dependence on economic growth, wage earnings and bureaucracies. Therefore it is meaningful in that social ecology gives the concepts of sustainability to welfare discourse, which can lead to theorizing about social welfare.

전자공시시스템(DART)을 활용한 국내 텍스트 분석(Textual Analysis) 환경에 관한 연구

본 연구는 금융감독원의 전자공시시스템(DART)을 통해 공시된 대량의 보고서들을 활용한 국내 텍스트 분석 연구 환경을 평가한다. 먼저 저자들은 대량의 공시서류를 내려받기 어려운 국내 전자공시 환경을 고려하여, 웹 크롤링 등을 활용한 우회적인 방법을 통해 1999년부터 2013년까지 공시된 총 111,497 건의 분기, 반기 및 사업보고서들을 내려받는다. 이후, Li(2008)의 연구방법을 응용하여 이들 보고서에서 "임원의 현황"표를 추출하는 비정형 데이터 마이닝 프로그램을 개발하고, 이를 바탕으로 전체 표본에 대한 텍스트분석 가능여부를 점검한다. 연구 결과, 전자공시시스템에 공시된 모든 분기, 반기, 및 사업보고서들 중 약 40%가 기계판독 불가능한 것으로 나타났다. 또한 기계판독이 가능한 보고 서들의 경우에도, 문서가 PDF 형식으로 제공되고 있어 효과적인 텍스트 분석을 위해서는 TXT 혹은 HTML 형식으로의 추가적인 변환작업이 필요한 것으로 나타났다. 최근 미국을 중심으로 각종 기업 공시자료들을 활용한 다양한 텍스트 분석이 진행되는 등 그 중요성이 점차 대두되고 있는 상황을 고려할 때, 본 연구의 결과는 국내 텍스트 분석 연구를 보다 활성화시키기 위해 DART 시스템의 개선이 선행되어야 한다는 점을 시사한다. In the United States, there is an increasing interest in the application of computer-based textual analysis and a large body of prior accounting literature has analyzed the textual contents of corporate filings such as annual reports. However, due to the lack of institutional supports and relevant experiences, neither practitioners nor researchers in Korea have used textual analysis. Given the circumstances, this study examines whether the Korea Financial Supervisory Service(FSS)``s on-line Data Analysis Retrieval and Transfer(DART) system offers adequate research environment for the textual analysis on corporate filings. By replicating a textual analysis procedure used in prior study, we point out some flaws and limitations of current DART system and suggest potential solutions to encourage the textual analysis in Korea. First, we start by collecting the full sample of corporate annual reports provided in DART system. Unlike the EDGAR(Electronic Data Gathering, Analysis, and Retrieval) system in U.S. which allows information users to easily download massive amount of corporate reports through the anonymous FTP server, the DART system only provides web-based downloading system and does not facilitate users to download massive amount of reports instantly. In this study, we overcome this issue by utilizing a web-crawler program and collect 111,497 corporate annual(quarterly) reports from 1999-2013 period. However the development of web-crawler program requires information users to have certain level of programming skills, implying that this approach is not appropriate to be widely used. Moreover, it took approximately 372 hours to complete our collection using web-crawler which is three times longer that the time needed to collect the similar amount of corporate reports using EDGAR anonymous FTP server. Overall, our findings from the collection step indicate that current DART system is not suitable for downloading massive amount of corporate reports which is necessary to run the textual analysis. Second, from the collected samples, we extract "top executives status" table from individual reports with a text analyzing program that we develop following Li(2008). This procedure intends to check the machine-readability of texts and tables included in corporate reports and to further assess the environment of textual analysis using Korean data. With a similar method used by Li(2008) when extracting MD&A sections and footnotes from his U.S. sample annual reports, we try to obtain "top executives status" table from our Korean sample reports. We deem specific sentences that meet certain regular-expression conditions we define to be starting sentences of the "top executives status" tables. This text analyzing program is written by Python programming language and tested to ensure 99% or higher accuracy of extracting the table. The results indicate that the Korean DART system offers inadequate research environment for textual analysis on corporate filings. Particularly, corporate reports provided in PDF format act as constraints on analyzing the textual contests. In detail, 43,407 reports out of 111,497, which approximately is 40% of the total samples are found to be not machine readable. For these reports, computer failed to extract "top executive status" table meaning that none of the texts from the report could be used for textual analysis. Moreover, given the technical difficulties in reading PDF format, corporate filings that are machine readable require another conversion process before the textual analysis adding to the difficulty of analyzing massive amounts of data. Alternatively, we develop web automation program and web-crawler program in an attempt to collect the sample reports in a machine readable format. However, using these programs are time consuming works which require approximately 1,800 hours to complete our collection process. Considering that textual analysis on corporate filings are on the rise, our overall results reveal that the refinements of DART system must precede the active research on textual analysis of corporate filings in Korea. We propose two potential solutions to resolve the problems related to current DART system and encourage the textual analysis in Korea. First, as in the EDGAR system, DART system must construct an anonymous FTP server where the information users can easily access and download massive amount of reports. This may allow practitioners and researchers to actively engage in textual analysis and thereby extend the application of disclosed corporate reports. Furthermore, corporate managers would pay more attention to the non-numeric information included in their reports increasing the quality of disclosure. Second, DART system must make technical complements to its report format by providing additional format of TXT or HTML. PDF format report which is the only format of report that DART system provides has its advantage in terms of clarity and security. However, PDF reports require additional conversion process which significantly increases the time spent on running textual analysis. In addition, TXT and HTML formats are perfectly machine readable and can resolve the problems related to machine readability issue. This study contributes to the literature by examining the textual analysis research environment using DART system. In typical, we point out the flaws and limitations of DART system by comparing its relevant attributes with EDGAR system. Furthermore, we propose two potential solutions to resolve the problems and in turn encourage the textual analysis research in Korea.
