In general, a venture capital invests in tech startups and helps them improve the corporate transparency through board of directors. With respect to venture capital investment and its impact on the corporate transparency of the newly public firms from 2004 to 2010 in Korea, we have made regression analysis. First, it was found that it was likely to be less transparent, the larger its asset size or the higher its debt ratio was. Second, lower level of ownership-control disparity resulted in higher transparency. Third, a shorter period to IPO and higher growth rate were more prominent in companies with lower degree of transparency. The above findings were not conclusive to prove whether or not venture capital directly increases the transparency level of its portfolio companies, but do insinuate the possibility of a negative impact on the transparency of its investee companies, as early IPO's were associated with less transparency. This is all the more persuasive as it was observed that companies with a lower level of transparency had generally raised more money from venture capitals, and that companies with a higher growth rate and/or higher PBR, have shown to be less transparent.

The physicochemical properties and nutritional components of fermented black jujube (FBJ) were compared with those of dried jujube (DJ) to improve their utilization as food materials. The moisture contents and brix of the DJ and FBJ were 22.6% and 6.07 brix, and 10.36% and 7.23 brix, respectively. Their L values were 34.78 and 31.82, and the a and b values of DJ were higher than those of FBJ. DJ had a lower water activity level (0.75) than FBJ (0.45), but FBJ had a higher amount of reducing sugar and soluble protein than DJ. The major free sugars in the two types of jujube were fructose and glucose, and their potassium content was highest (about 90%) among minerals. Their unsaturated fatty acid contents were 51.0% and 59.83%, respectively, and the major fatty acids myristoleic acid, palmitic acid, and palmitoleic aid were detected in them.

The purpose of this study is to improve the quality of white pan bread by adding polymannuronic acid, an excellent rheological properties material which has the high blood control function in seaweeds, to flour. To investigate the rheological properties appropriate to the making of white pan bread, amylograph, farinograph, extensography were done adding polymannuronic acid(0%, 1%, 3%, and 5%) to flour. The gelatinization condition between flour and compositic flour, amylogram was done. The result was that the gelatinization temperature in flour(100%) was $61.0^{\circ}C$, as polymannuronic acid rate was increased by 1%, 3%, 5%, thetemperature was all the same, $63.5^{\circ}C$. The maximum viscocity temperature of flour(100%) was $92.0^{\circ}C$. that of flour added polymannuronic acid (1%) $92.5^{\circ}C$, those of flour added polymannuronic acid (3%, 5%) unchangeable. $\alpha$ -amylase activity degree, maximum viscocity was that flour(100% was 525 BU, flour added polymannuronic acid (1%) 498 B.U, flour added polymannuronic acid (3%) 385B.U, flour added polymannuronic acid (5%) 360 B.U, highly decreased. Farinograph was done, as the additional quantity of polymannuronic acid increase(1%, 3%, 5%), water absorption rate increase much more thin the control. As the additional quantity of polymannuronic acid is added from 1% to 3%, development time of dough was increase, but one added 5% was decreased. In case of extensograph was done, resistance of dough increased but extensibility is decreased, so R/E value increased.

The modern society has been drastically changed from the industrial economic society to the knowledge based society, to catch up with the knowledge and the change of technology required for the modern people, the people can not live in the modern society without the continued study or education. In case of architectural design firm, it is concentrating on the productivity of enterprise by cultivating the working level through the self education focused on the improvement of inner capacity. In connection with this, the efficiency of enterprises are analyzed by carrying out the Data Envelopment Analysis(DEA) utilizing the financial ratio index in the various field of industries recently, the analysis study for the efficiency utilizing DEA is increased in the construction industries as well. However, in case of construction industries, the study focused on the efficiency of administration only has been progressed, it is the real situation that the approach for the analysis of education efficiency of each enterprise is very insufficient. Therefore, this study analyzed the education efficiency of architectural design firm after the selection of input and output variables by utilizing the DEA model and utilizing the AHP analysis technique by deducting the variables through the preceding study in relation to the education efficiency and the interview with the specialists.

The construction industry has strong ties with other industries, and so construction company insolvency also has a strong influence on other industries. Prediction models addressing the insolvency of construction company have been well studied. Although factors contributing to insolvency must precede those of predictions of insolvency, studies on these contributing factors are limited. The purpose of this study is to analyze the influence of changes in the housing market on construction company insolvency by using the Vector Error Correction Model. Construction companies were divided into two groups, and the expected default frequency(EDF), which indicates insolvency of each company was measured through the KMV model. The results verified that 10 largest construction companies were in a better financial condition compared to relatively smaller construction companies. As a result of conducting impulse response analysis, the EDF of large companies was found to be more sensitive to housing market change than that of small- and medium-sized construction companies.

현재 공적연금제도의 하나인 사학연금은 일반 민간 기업에서 퇴직시에 지급하는 퇴직금과 유사한 성격의 '퇴직수당' 급여를 지급하고 있다. 사립학교연금법에서 지급하고 있는 퇴직수당제도는 학교법인인 사용자가 지급할 의무가 있는 급여에 해당한다. 그러나 사립학교의 열악한 재정으로 인하여 학교법인이 지급하지 아니하고 이를 국가와 공단 및 대학의 일부가 이를 분담하여 지급하고 있다. 사학연금공단에서는 매년 236억원을 연금기금에서 지급하였으며, 동 금액은 기부금으로 손금산입되어 왔다. 그러나, 최근 들어 기부금의 손금 인정비율이 50%로 축소되어 실제 법인세를 납부하고 있다. 본 연구에서는 이러한 퇴직수당 공단부담금을 공단에서 부담하는 것이 타당한지 여부와 기부금으로 처리되는 것에 대한 타당성 여부 등에 대하여 세무회계적인 접근을 통해 법인세제개선을 위한 법 개정의 타당성을 살펴보고자 하였다. 본 연구는 퇴직수당 공단부담금이 기금회계에서 지급되어 기부금으로 보고 있는 기존의 예규에 대한 해석을 새롭게 하고 사학연금기금의 세무회계상 개선방안을 도출하고자 하였다. 퇴직수당의 급여지급은 엄밀하게 살펴보면 기금회계의 대상이 아니라 연금제도의 고유사업인 연금회계의 대상으로 보는 것이 타당하다. 이와 같은 현행 공단의 회계처리 및 기금회계 과세대상의 문제점을 인지하고 이를 면밀히 분석해보고자 한다. 본 연구는 사학연금기금의 법인세 부담으로 인한 연금재정악화를 사전에 방지할 뿐만 아니라 사학연금기금에 대한 안정화를 도모하고자 하는 방안 연구의 일환으로 법적 개선안 도출을 목적으로 하고 있다. 공단은 사립학교 법인을 대신하여 공단에서 대신 지급하면서도 이에 대해 기부금으로 보는 규정으로 인해 법인세를 납부하고 있어 부담금을 대신하여 납부하면서 법인세도 부담하고 있는 이중부담을 안고 있는 것이다. 본 연구에서는 이와 같은 사항을 토대로 다음과 같이 개선방안을 제시하고자 한다. 우선, 공단내부회계규정의 수정을 통해 퇴직수당의 연금회계 적용을 주장하고자 한다. 퇴직수당제도는 연금급여와 관련된 것으로 비과세대상의 고유목적사업 회계에 해당됨에도 불구하고 퇴직수당을 기금회계에서 기부금으로 처리하는 것은 법 논리상 타당하지 않다고 본다. 둘째, 학교법인을 대신하여 기금에서 대신 지급하였다는 것은 연금제도를 유지하기 위해서 연금법상에서 강제로 부과된 부담금으로 이를 필요경비로도 보아야 한다. 셋째, 학교경영기관이 마땅히 부담하여야 할 부담금임에도 불구하고 사학연금기금에서 부득이하게 지급하고 있음을 감안하여 퇴직수당부담금은 현행의 법인세법상 기부금 한도초과 대상에서 제외하는 특례규정을 신설하는 것이다. 본 연구는 최근 법인세가 과세되고 있는 사학연금기금의 과세 문제점을 살펴보고 이에 대한 개선방안을 제시하였다는 점에서 기존 연금제도의 틀 안에서 퇴직수당제도의 법적 부담을 검토한 연구와는 달리 법인세법상의 세무적 검토를 하였다는 점에서 의의가 있다고 할 수 있다.

The purpose of this study was to propose a model which is suitable for the actual delivery system by designing a fetal delivery hospital operation management and fetal health classification model. The number of deaths during childbirth is similar to the number of maternal mortality rate of 295,000 as of 2017. Among those numbers, 94% of deaths are preventable in most cases. Therefore, in this paper, we proposed a model that predicts the health condition of the fetus using data like heart rate of fetuses, fetal movements, uterine contractions, etc. that are extracted from the Cardiotocograms(CTG) test using a random forest. If the redundancy of the data is unbalanced, This proposed model guarantees a stable management of the fetal delivery health management system. To secure the accuracy of the fetal delivery health management system, we remove the outlier which embedded in the system, by setting thresholds for the upper and lower standard deviations. In addition, as the proportion of the sequence class uses the health status of fetus, a small number of classes were replicated by data-resampling to balance the classes. We had the 4~5% improvement and as the result we reached the accuracy of 97.75%. It is expected that the developed model will contribute to prevent death and effective fetal health management, also disease prevention by predicting and managing the fetus'deaths and diseases accurately in advance.

This study examines one of the conventional and controversial issues in modern finance. Specifically, this study identifies financial determinants of corporate R&D intensity for firms belonging to Korean Chaebols. Empirical estimation procedures are applied to derive more robust results of each hypothesis test. Static panel data, Tobit regression and stepwise regression models are employed to obtain significant financial factors of R&D expenditures, while logit, probit and complementary log-log regression models are used to detect financial differences between Chaebol firms and their counterparts not classified as Chaebols. Study results found the level of R&D intensity in the prior fiscal year, market-value based leverage ratio and firm size empirically showed their significance to account for corporate R&D intensity in the first hypothesis test, whereas the majority of explanatory variables had important power on a relative basis. Assuming that the current circumstances in the domestic capital market may necessitate gradual changes of Korean Chaebols in terms of their socio-economic function, the results of this study are expected to contribute to identifying financial antecedents that can be beneficial to attain optimal level of corporate R&D expenditures for Chaebol firms on a virtuous cycle.

The purpose of this study is to analyze how Corporate Real Estate Ratio affects Firm's Value for KOSPI Companies and KOSDAQ Companies. The period of analysis is the period of the Financial Crisis (2007-2008), the period immediately after the Financial Crisis (2009-2011), and the period following the introduction of IFRS (2012-2016). The samples of 2761 KOSPI Companies years and 3719 KOSDAQ Companies years are used in this study. The result of Regression Analysis shows that the higher Corporate Real Estate Ratio is, the more negative Firm's Value is. In the comparison of markets, both KOSPI Companies and KOSDAQ Companies had no statistically significant effects during the Financial Crisis. Although KOSDAQ Companies had a greater negative effect on the Firm's Value than KOSPI Companies right after the Financial Crisis, KOSPI Companies have had a greater negative influence on the Firm's Value than KOSDAQ Companies since the introduction of IFRS. Therefore, each corporation should pay more attention to identifying the appropriate amount of their Corporate Real Estate Ratio and should continue to analyze and make decisions on the most efficient use of real estate which is owned by each company. This study shows speciality in dividing into three period, such as the period of the Financial Crisis, the period immediately after the Financial Crisis, and the period following the introduction of IFRS and comparing the degree of influence on the KOSPI Companies and KOSDAQ Companies for the each period. I hope to study the factors that affect the company's real estate policy.
