기업공개(Initial Public Offering, IPO)는 기업의 중요한 전략 중 하나로 IPO를 통해 가치를 평가받고 보상받으며 다음 단계로의 성장을 위한 자본을 조달할 수 있다. 본 연구에서는 CEO의 개인적 특성이 IPO까지의 소요기간에 미치는 영향을 분석하였다. CEO의 나이, 관련 전공 여부, 최종학력, 이전 업무경험이 IPO까지의 소요기간을 단축할 것이라고 가설을 제시하였다. 코스닥 벤처기업부, 신성장기업부에 상장한 318개 기업을 대상으로 분석한 결과, 기업 공개까지의 소요기간에는 CEO의 나이, 전공(의학계열), 최종 학력 등이 부(-)의 영향을 미치는 것으로 나타났다.

This study investigates empirical issues that have received little attention in the previous research in the Korean capital market. It is to find any financial determinants on the capital structure for the firms listed in the KOSDAQ(Korea Securities Dealers Automated Quotation). Another test is performed to find any possible discriminating factors by utilizing a robust methodology, which may distinguish between the firms belonging the 'prime section' and the 'venture section' in terms of their financial aspects. Moreover, the null hypothesis that the changing trend or movement of a firm's capital structure with respect to its industry mean (or median) may be random, is also tested. For the book-value based debt ratios, size(INSIZE), growth(GROWTH), Market to book value of equity(MVBV), volatility(VOLATILITY), market value of equity (MVE) and section dummy (SECTION) showed their statistically significant effects on the book-value based leverage ratios, respectively, while size(INSIZE), growth(GROWTH), market value of equity(MVE), beta(BETA) and section dummy (SECTION) showed their statistically significant effects on the market-value based leverage ratios. This study also found an interesting result that a firm belonging to each corresponding industry has a tendency for reversion toward its mean and median leverage ratios over the five-year tested period.

Launching truss used for constructing the precast segmental concrete bridge has upper chord, lower chord and diagonal members. And the pin is used for connecting these members. From the field loading test carried out for investigating the actual behavior of launching truss, the great difference is analyzed between measured stress and calculated stress. Based on measured value, the structural analysis are carried out about assumed abnormal behavior of connection part. From the results of analysis, it is analyzed that the abnormal behavior of connection part greatly affect the structural behavior of launching truss. In addition, from the investigation of safety of launching truss, it is evaluated that the launching truss has enough safety with normal behavior of connection part.

A butterfly valve is a type of flow-control device typically used to regulate a fluid flow. This paper presents an estimation of the shape parameter of the Weibull distribution, characteristic life, and $B_{10}$ life for a concentric butterfly valve based on a statistical analysis of the reliability test data taken before and after the valve improvement. The difference in the shape and scale parameters between the existing and improved valves is reviewed using a statistical hypothesis test. The test results indicate that the shape parameter of the improved valve is similar to that of the existing valve, and that the scale parameter of the improved valve is found to have increased. These analysis results are particularly useful for a reliability qualification test and the determination of the service life cycles.

Attitude toward the advertising is widely used in studies of traditional mass media advertising. As internet marketing becomes more important, attitude toward the website will gain parallel status in evaluating effectiveness. And also, studies on relationship among attitude toward the website, attitude toward the advertising, attention to the commercial, attitude toward the brand, & purchase intention was needed. This study sets a hypothetical model about the relationship among attitude toward the website, attitude toward the advertising, attention to the commercial, attitude toward the brand, & purchase intention. And to testify this model, 10 hypotheses were set. The results of the analysis, all variables were related significantly.

The purpose of this paper is to provide values and effectiveness to libraries making a new social network service marketing model and strategy. According to study, when libraries entice library users with social network services, the users become loyal customers who give libraries long-term supports. For method of study, it establishes 15 hypotheses and proves those hypotheses with 157 responders. After inspecting hypotheses, 13 hypotheses are adopted and 3 hypotheses are dismissed. During the research, it is verified that usefulness perceived by library users is the most important factor of user satisfaction and continuous use intention which increased library users' intention to continue visiting the library. In addition, effectivness of marketing and cause are found in order of system quality, information quality, reliability, interactivity, subjective norms. In other words, the study found that library users found their information for using social network services and this attribute affects user satisfaction and ultimately continuous use intention in a positive way.

While the importance of adopting cloud computing service has been emerged, comparatively little research has been conducted on examining factors of an individual user's intention to switch toward cloud computing service. Hereafter, this study presents and empirically tests users' intention to switch to cloud computing. Our model posits that the characteristics of cloud computing such as effectiveness, economics, accessability, switching cost, security concern, and satisfaction toward existing IT service to cloud service affect perceived value, which in turn, influences intention to switch. An experimental study using student subjects provided empirical validation for our proposed model. Survey data from 204 respondents was used to test the model using partial least square analysis. As the result of the analysis, five hypotheses out of seven hypotheses were supported. According to our results, among the characteristics of cloud computing, effectiveness, economics, switching cost, and security concern were found to have significant impact on users' intention to switch that mediated by perceived value. Based on our research findings, we hope that this research will stimulate researchers' interest in the emerging area of cloud computing adoption.

In order to understand how various support programs affect the development of traditional performing arts, I used descriptive statistics and multivariate statistics analysis on 267 surveys. I estimated relationship between item-whole by calculating mean and standard deviation. This will help us comprehend effects of the variables. Cronbach alpha coefficient, a measure of internal consistency, exceeded 0.7, indicating that reliability is satisfactory. I have established one main hypothesis and four sub-hypothesis to identify the relationship between support programs and the performing arts more clearly. The result supports that the support programs do have effects on the performing arts. However, there are not enough researches done on this subject, and additional researches are needed in order to systemize relevant theories and the development of performing arts industry.

This study attempted to analyze factors influencing S-DMB adoption. The theoretical background of this study is 'Technology acceptance model.' Based on this theory and literature review this study set 5 hypotheses. For this research, a survey was conducted by online research lab. from October 25 to 31. Data were collected from 350 subjects. Complete and useable questionnaires were received from 303 respondents. The result and conclusion are as follow: 'Instant accessibility,' 'service quality,' 'Cost,' 'advertising,' 'perceived easy of use' are significant factors influencing 'perceived usefulness'. 'Compatibility,' is a significant variable influencing 'perceived easy of use'. However, 'self efficacy' and 'innovativeness' are not significant factors influencing 'perceived easy of use.' The result of the analysis showed that most of the hypotheses were verified the same as preceding studies, but some results were different with the result of preceding studies. Therefore, it implies the characteristics of S-DMB different with other IT systems and mass media that were research subject mostly before, and it influences the result of this study as well.
