As we know Dance is an action which communicates emotions and thinkings of an individual through the skillful movement. For this study it was necessary to make a statistic. I made this study during eight weeks. Each week with five days so total was 40 days. During five days we made practice with total of 60 students divided in three groups, each group had 20 students of kyongbuk Art High School in Teagu. The groups was as follow : 1. Physical practice group. 2. Mental practice and physical practice group. 3. Control practice group. 1. Physical practice group : I founded that this group was more effective than that of control practice group. (expression, skill) 2. Mental practice and physical practice group : the combination of mental practice and physical practice group is more effective than the physical practice group and the control practice group. 3. Control practice group : At the beginning of the statistic this group got the highest score among the two other groups above mention, but I founded also at the end of the 8th week experiment that this group made a quick retrogression so they got a very low score at the end. Being based on the result of statistic before and after the measuring value, the three experimental groups had a remarkable difference.(P<0.01) This study will provide foundation to the theory of excellent performance through psychological skill training.

이 논문은 전 세계 상위 61개의 해운기업을 대상으로 2009년부터 2013년까지의 자료를 이용하여 자본조달에 관한 기업의 특성과 재무건전성과의 관계를 분석하였다. 패널 데이터를 이용하여 FGLS 회귀분석을 실시하는 연구방법을 사용하였다. 실증분석결과 자산의 유형성이 재무건전성과 깊은 관련이 있음을 발견하였다. 유형자산의 비율이 높은 기업일수록 부채의존도가 높게 나타났다. 또한 해운기업의 유동부채비율이 재무건전성에 영향을 미치는 중요한 요인으로 나타났다. 한국의 해운기업 뿐만 아니라 전 세계 해운기업들의 현재 재무구조는 단기 운영자금의 의존도가 상당히 높다고 할 수 있다. 해운기업은 재무구조의 건전성을 개선시키고 경영효율성을 높이는 구조조정이 필요하다. Companies that have a solid financial structure tend to increase a debt level to the extent that they can afford to maximize their shareholder value. But if the debt level becomes higher, the cash flow from operating activities decreases. The decrease of after-tax cash flow will induce a higher risk of insolvency. This study analyzes the factors that influence the financial stability and that are likely to have a decisive impact on a company`s survival and bankruptcy. It focuses on the relationship between the characteristics of the shipping companies and their financial soundness by using the data of the world`s top 61 shipping companies from 2009 to 2013. Feasible Generalized Least square(FGLS) regression analyses are conducted for the empirical study using panel data. The study finds that the tangibility of assets of shipping firms is closely related to financial soundness. Shipping firms with higher tangible assets have easy recourse to debt, because vessels can serve as collateral. In addition, the study finds that the liquidity ratio of shipping firms is associated with financial stability. Current liabilities account for about 80% of the equity in shipping companies. Further, shipping companies are found to have low stability of the capital structure. Therefore, they need to restructure the organization to enhance their effectiveness and financial soundness.

유럽행 컨테이너 화물의 철도 운송경로에 관한 연구

The maritime transportation has been largely used for the trade between Korea and the EU even if the two partners are located in the Eurasian continent Recent improvement of railway, linkage system in border areas, and safety level leads to the increased use of railway transportation such as the Trans-Chinese Railway(TCR) and the Trans-Siberian Railway(TSR). Korean shippers choose either the TCR or the TSR as a means of railway transportation with respect to their priority consideration. The short running distance and low damage level of freight are cost saving factors of TCR However, since gauges in the outside China are different and same in the EU, frequent transshipment is needed when crossing borders. This creates delayed clearances and waiting time for quarantine. By contrast, the TSR passes less borders and encounters less gauge differences, thus less transshipment Though the physical length of the TSR between Korea and the EU is longer than that of TCR, the transportation time with the TSR is advantageous. However, by the fact that the railway is located in a polar climate region, freight damage is frequent in winter.

온라인 기업의 가치에 영향을 미치는 요인

여희정 ( Hee-jung Yeo ) 한국통상정보학회 2019 통상정보연구 Vol.21 No.3

이 논문은 세계 유가증권시장에 상장된 상위 100대 온라인 기업을 대상으로 기업의 가치에 영향을 미치는 요인을 파악하였다. 2009년부터 2017년까지 8년간의 회계연도 재무제표의 정보를 이용하여 자본구조이론을 검증하고자 하였다. 무형자산, 잉여현금흐름, 레버리지, 수익성, 최고경영자의 자기과신, 재무불안정성 등을 독립변수로 하고 시장가치/장부가치와 주가를 종속변수로 하여 일반화선형모형(Generalized linear model; GLM)을 이용하여 실증분석하였다. 실증분석에서 무형자산과 기업가치가 음(-)의 방향으로 작동하는 것을 발견하였다. 재무불안정성과 기업가치는 음(-)의 관계를 발견했지만, 부채증가율과는 관련이 없다는 것도 발견되었다. 온라인 기업이 보유한 잉여현금흐름과 초과현금은 기업가치를 높이는 중요한 변수이다. 자기과신적 최고경영자가 통계적으로 유의하게 온라인 기업의 가치에 영향을 미치는 것으로 나타났다. 부채비율과 기업가치와 음(-)의 관련성이 있다는 사실을 통해 자본조달의 순서이론을 증명하였다. This paper has examined factors affecting firm value for online companies worldwide. The purpose of this study is to verify theories of capital structure using information on financial statements for eight fiscal years from 2009 to 2017. We conducted a generalized linear model(GLM) regression analysis using market to book value and stock price as dependent variables and intangible assets, free cash flow, leverage, profitability, CEO's self-confidence and financial instability for independent variables. In empirical analysis, we found that intangible assets and firm value operate in a negative direction. It was also found that firm value is negatively related to financial instability but not related to debt growth rate. The free cash flow and excess cash held by online companies are important variables that increase corporate value. Self-confident CEOs have a statistically significant effect on the value of online firms as well. We have proved the pecking order theory of capital procurement through the fact that there is a negative relationship between debt ratio and firm value.

여희정 ( Hee Jung Yeo ) 한국해운물류학회(구 한국해운학회) 2011 해운물류연구 Vol.27 No.4

본 논문에서는 중국과 유럽 주요항만의 상대적 효율성을 분석하였다. 이를 위해 중국 항만 10개, 유럽 항만 10개 총 20개 항만을 대상으로 2009년 자료를 이용하였다. 연구방법으로 DEA모형을 이용하여 항만별 기술효율성(technical efficiency), 순수 기술 효율성(경영효율성, pure technical efficiency), 규모의 효율성(scale efficiency)을 측정하였다. 분석결과 상해 항, 홍콩 항, 선전 항, 닝보 항, 례윈강 항, 이탈리아의 지오이아 타우로 항만이 가장 효율적인 것으로 나타나고 있다. This paper examines the relative efficiency of European and Chinese major ports. The analysis of efficiency is based on 20 largest ports in China and Europe respectively for 2009 by applying the Data Envelopment Analysis (DEA). I have analysed the technical efficiency, pure technical efficiency and scale efficiency of ports. Shanghai Port, Hong Kong Port, Shenzhen Port, Ningbo Port, Lianyungang Port and Gioia Tauro port are found to be highly efficient than other sample ports in terms of the technical efficiency pure technical efficiency and scale efficiency.

강주희(Kang Joo-Hee),김선응(Kim Seon-Eung),여희정(Yeo Hee-Jung) 한국체육과학회 2002 한국체육과학회지 Vol.11 No.1

The purpose of this study was to investigate the level of sport competition trait anxiety among volleyball players. To meet this purpose, 468 subjects were recruited, 119 drawn from middle school players, 159 from high school players, 81 from university players, and 109 from professional team players. Among them, 196 subjects were female, and 272 subjects were male. The age range of the subject was from 14 years old to 32. Marten's Sport Competition Anxiety Test(SCAT) was applied to the whole subject to measure their competition trait anxiety. The data gathered were analyzed by t-test and ANOVA after sorted by gender, grade, length of playing experience, position, and team performance level. The results were as follows : 1. The anxiety level of female players were higher than that of male players in all groups of the middle school, high school, and professional team. 2. High school players showed the highest level of anxiety when compared to the other groups. 3. The more experienced a player was, the more lowered his/her anxiety level was. 4. 'There was no significant difference among subject groups as for the anxiety level according to position. 5. 'There was no significant difference among subject groups as for the anxiety level according to team performance level. Based on the above results, it was suggested that future studies empirically examine the effect of an anxiety reduction training on adolescents' performance.
