  • The purpose of this study was to develop the Constraints in Physical Activity Scale for people with physical Disabilities(CPASD) which measures the constraints in physical activity of people with physical disabilities. For this study, the 5 step analytic framework of unified validity developed by Messick (1995), the framework for conducting a strong program of construct validation by Benson (1998) method were applied. Furthermore, the validity of CPASD was systematically presented by applying common factor model and measurement model to 264 persons with physical disabilities. The conclusion based on the results and discussions of this study is as follows. First, CPASD presented evidence of job validity. Four factors (17 items) were developed, consisting of leader constraints, economic constraints, prejudice, and exercise environment constraints through the analysis of the factor structure and the fit of factor coefficients. Second, the factor structure of the developed CPASD (leader constraint, economic constraint, prejudice, exercise environment constraint) was statistically distinguished and stably reflected the existing exercise participation constraints theory. Third, the developed CPASD presented evidence of the validity of the criteria. Leader constraints and prejudice were negatively correlated with positive motor emotions, leader constraints, prejudice, and exercise environment constraints were positively correlated with negative motor emotions. Therefore, in future research, it is necessary to reevaluate the current system and actual condition related to leader constraints, economic constraints, prejudices, and exercise environment constraints derived as factors of CPASD. To do this, it is necessary to judge the degree of reality based on the causal relationship verification and IRT theory using CPASD.

  • In this paper, we study empirically the relations between financial constraints and dividend adjustment speed of innovative small and medium sized enterprises (SMEs) listed on Kosdaq Market of Korea Exchange. The main results of this study can be summarized as follows. Determinants suggested by the major theories of dividends, namely, residual dividend theory, dividend signaling theory, agency theory, catering theory, and transactions cost theory explain significantly the dividend payout policy of Kosdaq SMEs. Lintner's dividend adjustment model indicates that Kosdaq SMEs have long run target payout ratio, and that Kosdaq SMEs adjust partially the gap between actual and target payout ratio each year. In the core variables of Lintner (1956) dividend adjustment model, past DPS has more effect than current EPS. These results suggest that Kosdaq SMEs maintain stable dividend policy which maintain past DPS level without corporate special reasons. Dividend adjustment speed of innovative Kosdaq SMEs is more fast than that of uninnovative Kosdaq SMEs, and dividend adjustment speed of financial unconstrained innovative Kosdaq SMEs is faster than that of financial constrained innovative Kosdaq SMEs. Futhermore, dividend adjustment speed of innovative Kosdaq SMEs classified by Small and Medium Business Administration is faster than that of unclassified innovative Kosdaq SMEs. The former is linked with financial policies and services like credit guaranteed service, venture investment fund, insurance program, and so on. In conclusion, past DPS and current EPS suggested by the Lintner's dividend adjustment model explain mainly dividend adjustment speed, and financial constraints explain also partially. Therefore, if managers of innovative Kosdaq SMEs can properly understand of the effects of financial constraints on dividend smoothing, they can maintain constantly dividend policy. This is encouraging result for Korea government as it has implemented many policies to commit to innovative Kosdaq SMEs.

  • This paper is a theoretical inquiry of the changing roles of digital technologies in the representation of risk. Critically examining existing perspectives on risk society and risk communication, this paper argues that digital technologies and images in risk communication have been relatively understudied. Having said that, this paper suggests that Actor-network Theory provide useful theoretical tools for current studies on how digital technologies affect contemporary risk communication practices. Furthermore, this paper examines varied recent studies investigating how digital technologies of visualization are at play in risk communication practices. In doing so, this paper demonstrates how digital images and technologies interrupt the processes that scientific evidence is presented and facts are constructed in varied contemporary scientific reasoning. It will focus on the emerging mode of seeing and visual regime made possible by the increased usage of digital image and technologies, which are characterized by networked connection, sensor, computerized algorithm, and increased storage space. Finally this paper will discuss on the implications on future studies on the roles of digital images and technologies in risk communication practices in Korean context.

  • The purpose of this paper is to test the market timing hypothesis and impact of macro economic variables on capital structure choice as well as the traditional static trade-off and pecking order theories of capital structure in a integrated framework. Through a two stage test of target capital structure and capital structure choice, none of theories was consistently supported, but most of them were partly supported. In the first stage analysis of target ratio, coefficients of firm-specific variables generally supported the predictions of pecking order theory rather than those of the static trade-off theory. However, the result of the second stage test on capital structure choice supported the hypothesis of the static trade-off theory, which claims that firms usually set and pursue the target leverage ratio. Further, the result of the seconde stage shows that a simple pecking oder theory does not hold because firms with deficit of internal fund tend to issue bonds rather than stocks to raise outside fund. Also, the result indicates that the market timing hypothesis holds because firms with over-valued stocks tend to issue stocks rather than bonds. However, contrary to Korajczyk and Levy(2003), the impact of macro economic variables such as term or credit spreads on capital structure choice was negligible, and the impact of macro economic and market timing hypothesis variables were not greater in financially unconstrained firms as Korajczyk and Levy(2003) suggested.

  • 19세기(世紀) 중반(中盤)에 시작된 선진국(先進國)들의 공업화(工業化)는 약 100년이 소요(所要)되었는데 동(東)아시아 신흥공업국(新興工業國)(NICs)들의 경우에는 20~30년이 소요(所要)된 것으로 추정된다. 후자(後者)의 공업화(工業化) 경험은 흔히 '동(東)아시아의 기적(奇蹟)'이라 불린다. 그러나 이 고속성장(高速成長) 혹은 압축성장(壓縮成長)이 가능했던 이유가 무엇이냐에 관해 경제학계(經濟學界) 내외(內外)에서 그리고 국내외(國內外)에서 일치된 의견이 없고, 특히 이 과정에서의 정부(政府)의 역할(役割)을 어떻게 평가하느냐에 관하여는 더욱 그러하다. 신고전(新古典) 경제학(經濟學)은 이 나라들의 가격왜곡(價格歪曲)의 최소화(最小化), 시장기구(市場機構)의 활용(活用), 국제분업(國際分業)에의 참여(參與)에서 주된 이유를 찾고 있는데 비해, 소위 수정주의(修正主義)는 이같은 견해가 사실과 크게 괴리가 있으며 '기적(奇蹟)'은 시장(市場)의 자원배분(資源配分)에 대한 정부개입(政府介入)이 주효(奏效)하였기 때문이라 주장한다. '동(東)아시아의 기적(奇蹟)'은 동(東)아시아란 지역(地域)에서 일어난 현상일 뿐 아니라 20세기(世紀) 후반(後半)에 일어난 동시대적(同時代的) 현상이기도 하다. 공업화(工業化)를 이룬 나라들은 모두 세계시장(世界市場)과 활발히 교역(交易)하였다는 공통점이 있는데, 세계시장(世界市場)의 규모(規模)를 대표하는 세계총수출(世界總輸出)이 19세기(世紀) 중반(中盤)과 20세기(世紀) 후반(後半) 사이에 실질기준(實質基準)으로 100배 이상 커졌다. 이 글은 세계시장(世界市場)의 규모증대(規模增大)가 동(東)아시아 NICs들의 고속성장(高速成長)의 이유(理由)였을 가능성(可能性)을 이론적(理論的)으로, 실증적(實證的)으로 검토해본 것이다. 이론적(理論的)으로는, A Lewis의 무한노동공급(無限勞動供給)(unlimited supply of labor)이 존재하는 경제(經濟)에서는 세계시장((世界市場) 상대가격(相對價格)이 불변(不變)인 한 제조업내(製造業內) 노동집약도(勞動集約度)가 높은 산업(産業)에 대한 투자유인(投資誘因)이 지속된다는 점에 고속성장(高速成長)의 근거가 있다고 보았다. 이러한 투자(投資)의 지속은 제조업부문(製造業部門)의 산출(産出)과 고용(雇傭)이 경제(經濟)에서 점하는 비중(比重)을 낮은 자원비용(資源費用)으로 증대(增大)시킬 것이기 때문이다. 실증분석(實證分析)에서는, 필요한 통계자료(統計資料)가 있는 19개국의 공업화(工業化) 경험(經驗)을 검토하였는데, 한 나라가 공업화(工業化)를 시작하는 시점(時點)의 세계총수출(世界總輸出)이 클수록 그 나라의 공업화(工業化) 소요기간(所要期間)이 단축(短縮)된다는 매우 확실한 증거가 있었다. 또한 동(東)아시아 NICs의 공업화(工業化) 소요기간(所要期間)이 선진국(先進國) 경험에 비해 약 1/4의 길이로, 혹은 그보다 더 짧게 단축(短縮)된 것은 거의 모두 세계총수출(世界總輸出) 규모(規模)의 증가(增加)로 설명될 수 있었다. 이같은 이론적(理論的) 근거(根據)와 실증적(實證的) 증거(證據)를 감안할 때, 우리 경제(經濟)는 정부주도형(政府主導型)이었으나 고속성장(高速成長)을 가능하게 한 것은 정부주도(政府主導)보다는 그 규모(規模)가 대폭 증대한 세계시장(世界市場)에서의 국제분업(國際分業)이었다.

  • This thesis is performed to suggest an objective and effective optimization plan of appraisal for archival values. Even though saving all of archives and records and passing them to descendants would be a strong preservation method, but preservation expenses cannot be ignored. Additionally the appraisal for archives is completed by selecting and preserving high-value records, preserving all of records seems not to be effective. In this aspects archivists have tried to find the appraisal standard to ensure the objectivity of it, however, existing studies cannot bring out positive method because of focusing on analyzing only theoretical analysis on appraisal. This study divides appraisal for archives in 3 steps; inquiry for the records creators, appraisal of archivists, appraisal of appraisal experts, and suggests the standard to increase objectivity and confidency of appraisal. The optimization plan of appraisal for archival values with the results of this thesis would influence on the revitalization of reappraisal for the archives in repository and archive of Korea.

  • The ownership structure of a franchise system is determined by the franchisor's strategic choice. A close look at the extant theories and perspectives in economics and management such as resource scarcity theory, agency theory, transaction cost analysis, and mixed ownership theory reveals that firms choose their ownership structure for the sake of economic efficiency, profit potentials, the chance of survival, and other strategic concerns. The present study, on the basis of strategic choice perspective, reviews the divergent theories of a franchise system's ownership structure and its determinants, thus providing a theoretical framework for comparing the contradictory arguments along the several critical dimensions. We also developed and tested the conflicting hypotheses regarding key determinants of ownership structure including firm's age, size, transaction-specific investments, uncertainty, and risk-sharing propensity. Using a FDD (Franchise Disclosure Document) data set of 543 Korean franchisors, we found that the years in business, the total number of employees, days of training, the inverse of the years of franchising, and the requirement of royalty payment have positive relationships with the proportion of company-owned outlets to total number of outlets. On the other hand, the proportion of company-owned outlets was found to have negative relationships with the total number of outlets and the extent of geographic dispersion of outlets, but to have no significant relationships with the initial investment required and the inverse of contract length. Based on the findings, we provide several theoretical and managerial implications for studying ownership structure of franchise systems.

  • This paper performed empirical tests of the validity of the pecking order theory which explains financing behavior of firms under information asymmetry. The results of regression analyses using the data of listed manufacturing companies in the Korean Stock Market from 1981 to 2010 have shown strong evidences supporting the pecking order theory. Especially regression coefficients of change of debt on funds deficit and control variables were found to be almost (+1) with statistically significance, which is interpreted as being consistent with the pecking order theory. Same results were found when I performed regression analyses by dividing the sample period into pre-currency crisis period, currency crisis period and post-currency crisis period and using 2 regression models. Change of tangible asset were found to function as collateral rather than reducing information asymmetry and as the firm size decreased, use of debt increased and as profitability increased use of debt decreased, which are consistent with the pecking order theory.

  • 우리는 최근 현대천문학의 가장 오래된 난제로 우리은하 헤일로의 형성과 깊은 관련이 있는 구상성단계의 오스터호프 이분법이 다중항성종족 패러다임 하에서 76년 만에 완벽히 규명되는 것을 발견하였다. 또한 이 연구의 기본 개념을 우리은하 벌지에 적용한 결과, 기존 국제학계의 이론과 완전히 다른 벌지의 형성기원에 대한 새로운 해석에 도달하였다. 우리은하의 벌지에 대한 대규모 측광 서베이 분석으로부터 double red clumps가 있다는 것이 2010년에 발견되었고, 이는 디스크와 바 불안정에 기인하는 은하중심부 X-shape 구조의 증거로 널리 받아들여지고 있다. 그러나 우리는 이와 같은 국제학계의 해석이 수평계열성의 항성진화이론을 간과한데서 비롯된 허구일 가능성을 제시하고자 한다. 우리의 모델에 의하면 관측된 double red clumps는 Omega Cen을 포함하는 대다수의 구상성단에서 발견되는 것과 동일한 헬륨함량이 증가된 2세대 별들(G2)에 의한 효과이다. 우리은하 벌지에 위치한 Terzan 5 구상성단처럼, 중원소함량이 높은 벌지에서는 G2에 해당하는 수평계열성들이 광도가 약 0.5등급 더 밝은 red clump 위치에 놓이게 되어 자연스럽게 double red clumps를 형성하게 된다. 앞으로 우리의 새로운 해석이 Gaia에 의한 삼각시차 거리결정으로 확인된다면, 이는 우리은하 벌지를 이루는 대부분의 별들이 Terzan 5와 같은 윈시 빌딩블럭들의 합병과 붕괴에 의해 형성되었다는 것을 암시하여, 우리은하는 물론, 조기형은하의 형성기원 연구에 큰 전환점이 될 것으로 기대한다.
