This study performed comprehensive tests on the four hypotheses on the capital structures for the firms listed in the KOSPI during the period from 2006 to 2011. It may be of concern to find any financial profiles on firms' leverage across the book- and market-value bases since there was relatively little attention drawn to any financial changing profile of the leverage surrounding the period of the pre-and the post-global financial crises. The findings of this study may also be compared with those of the previous related literature, by which it may be expected to enhance the robustness and consistency of the results across the different classifications on capital markets. It was found that three explanatory variables such as PFT, SIZE, and RISK, were found to be the statistically significant attributes on leverage during the tested period. Moreover, the outcome by the Fisher Exact test showed that a firm belonging to each corresponding industry may possess its reversion tendency towards the industry mean and median leverage ratios.

The team's performances were analyzed by evaluating the scores gained by their offense and the scores allowed by their defense. To evaluate the team's attacking and defending abilities, we also considered the factors that contributed the team's gained points or the opposing team's gained points? In order to analyze the outcome of the games, three prediction models were used such as decision trees, logistic regression, and discriminant analysis. As a result, the factors associated with the defense showed a decisive influence in determining the game results. We analyzed the offense and defense by using the response variable. This showed that the major factors predicting the offense were non-stop pass and attack speed and the major factor predicting the defense were the distance between right and left players and the distance between front line attackers and rearmost defenders during the game.

본 연구에서는 국내 공모 부동산펀드를 임대형과 대출형으로 나누어 이들 펀드수익률의 결정요인을 분석하여 보았다. 펀드수익률은 왜도와 첨도가 매우 높은 분포를 따르기 때문에, 본 연구에서는 회귀분석으로 추정된 잔차가 정규분포를 따르도록 극단 관찰치를 충분히 제거한 표본을 사용하였다. 분석 결과, 부동산펀드의 (초과)수익률에 영향을 주는 유의적인 요인으로 규모, 운용보수, 기간 등이 발견되었다. 또한 특이하게도 이들 결정요인은 두 유형에 대해 각기 상반된 방향으로 영향을 주고 있다. 임대형 부동산펀드의 경우는 규모, 운용보수가 펀드수익률에 유의미한 음의 영향을 미치는 반면, 대출형 부동산펀드의 경우는 규모, 운용보수 및 기간도 펀드수익률에 유의적인 양의 영향을 주었다. 이러한 결과는 국내 공모 부동산펀드는 임대형과 대출형이 매우 다른 경제적 성격을 가지고 있으며 향후 연구에서도 두 유형을 분리할 필요가 있음을 시사한다.

Recently, with the conversion towards knowledge-based economy era, the importance of the evaluation for patent valuation has been growing rapidly because technology transactions are increasing with the purpose of practically utilizing R&D outcomes such as technology commercialization and technology transfer. Nevertheless, there is a lack of research on determinants of patent valuation by analyzing technology transactions due to the difficulty of collecting data in practice. Hence, to suggest quantitative determinants for the patent valuation which could be applied to scoring methods, 15 patent valuation models domestically and overseas are analysed in order to assure the objectiveness for subjective results from qualitative methods such as expert surveys, comparison assessment, etc. Through this analysis, the important 6 common determinants are drawn and patent information is matched which can be used as proxy variables of individual determinant factors by advanced researches. In addition, to validate whether the model proposed has a statistically meaningful effect, total 517 technology transactions are collected from both public and private technology transaction offices and analysed by multiple regression analysis, which led to significant patent determinant factors in deciding its value. As a result, it is herein presented that patent connectivity(number of literature cited) and commercialization stage in market influence significantly on patent valuation. The meaning of this study is in that it suggests the significant quantitative determinants of patent valuation based on the technology transactions data in practice, and if research results by industry are systematically verified through seamless collection of transaction data and their monitoring, we would propose the customized patent valuation model by industry which is applicable for both strategic planning of patent registration and achievement assessment of research projects (with representative patents).

This study presents the determinants of R&D efficiency as the focus on CEO's competency, which influences R&D competency and R&D efficiency. The research samples are 6,708 technology-innovation small and medium-sized enterprises (SMEs). The independent variable is the R&D competency(existence of R&D organization, level of R&D personnel, R&D personnel management, R&D investment), the dependent variable is R&D efficiency. The moderator is the CEO's competency(experience level in its own industry, technical knowledge level, technology management strategy, management ability). R&D efficiency measures the relationship between inputs(level of R&D personnel, R&D investment) and outputs(patent applications, prototype) by the DEA. and the determinant analysis uses Tobit regression. As a result of the analysis, the existence of R&D organization and R&D personnel management is positively significant, level of R&D personnel and R&D investment is negatively significant for R&D efficiency. The moderating effect of CEO's competency on the relationship between the R&D competency and R&D efficiency is significant determinants of CEO's experience(experience level in its own industry, technical knowledge level) and technology management strategy. The finding is to measure the efficiency of R&D performance, and to analyze its determinants as the moderating effect of CEO's competency, using the technology appraisal data. In the conclusion session, the limitations of the research and future research directions were discussed.

동사의 종류와 곡용, 논항의 종류와 격 등 문장의 상을 결정하는 요인들은 여러 가지이다(Tenny 1994). 그러나 실제 자연언어처리에서 상 결정 요소들의 복잡한 조합은 기계가 문장의 상을 파악하는 작업을 더욱 어렵게 만들뿐이다. 본 논문에서는 다양한 상 결정 요인을 참조하지 않고 특정 부류의 부사에 의존하여 문장의 상을 결정하는 방법을 제안하고자 한다. 부사는 이른바 불변화사로 분류하는 품사 중의 하나로 통사적 혹은 형태소적 규칙의 적용을 받아 변형하지 않는다. 따라서 기계는 복잡한 형태소 분석을 통하지 않는 부사를 포착하기가 쉽다. 이와 같은 이점을 지닌 부사가 통사적 분석을 토대로 파악할 수 있는 문장의 의미인 상에 대한 표지임을 증명하여 자연언어처리의 간결함을 확보하고자 하는 것이 본 논문의 목적이다.

The purpose of this research is to set a standard for deciding competitive marketing prices of new supplying apartment houses and to analyze decision factors in sale price of supplying apartment houses with Analytic Hierarchy Process; the resulted model does not use the method that joins the land cost and the cost of construction together, but the method that compares the sales prices of surrounding apartments. This research tries to set a standard for decision of the prices of newly supplying apartment houses by classifying the determinants into the $1^{st}$ step(4 factors), the $2^{nd}$ step(9 factors), and the $3^{rd}$ step(25 factors). According to the process, the relative importance of decision factors in the sale prices is determined and this should be used as the index of sale prices for newly supplying apartment houses when the houses are provided. In addition, through the $2^{nd}$ step including 9 factors, the comparative model for sale prices is defined and the model is presented to be applied in the real business. Subsequent study additionally considering the factors apart from marketing which tries to find a generalized standard needs to be conducted.
