Crowdfunding has seen an enormous rise, becoming a new alternative funding source for emerging startup companies in recent years. Despite the huge success of crowdfunding, it has been reported that only around 40% of crowdfunding campaigns successfully raise the desired goal amount. The purpose of this study is to investigate key factors influencing successful fundraising on crowdfunding platforms. To this end, we mainly focus on contents of project campaigns, particularly their linguistic cues as well as multiple features extracted from project information and multimedia contents. We reveal which of these features are useful for predicting success of crowdfunding campaigns, and then build a predictive model based on those selected features. Our experimental results demonstrate that the built model predicts the success or failure of a crowdfunding campaign with 86.15% accuracy.

최근 들어 환경보전을 위해 국내외적으로 다양한 활동과 정책이 이루어지고 있다. 환경을 일방적으로 이용하던 기존의 건축은 환경을 보전하고 환경부하를 저감하는 방향으로 패러다임의 전환에 따라 환경친화적 건축물로의 전환이 요구되고 있다. 이에 따라 건축물은 초기 기획단계에서부터 건설, 유지관리, 철거/해체에 이르는 라이프싸이클에서 에너지 소비와 이산화탄소, 폐기물 등의 환경부하를 평가하고 이를 토대로 하여 환경친화적 건축자재, 재료선택과 환결친화적 계획요소기술 등이 적용되어야 할 것이다. 건축물의 라이프싸이클에서 환경에 미치는 영향을 파악하기 위해서는 건설, 사용/유지관리, 철거/해체과정에서 요구되는 에너지와 환경부하를 총량화하는 수단이 필요하다. 본 논문에서는 건축물의 라이프싸이클에서 에너지 소비량과 이산화탄소 배출량을 정량화하는 방법을 제시하고 있다. Recently, various activities and interest for the environment conservation are conducted in the world. These show that the environment is no longer object which is used by human on one side, but it should be accentuated for coexistence. With limit resources, we should use it effectively and efficiently. On coming the new paradigm for the environment conservation, all of the industries should be required to diminish the resource use and the environmental load such as Green House Gases (GHG's) and waste. With a step of all industries, the building industry has changed into effective use of resource and energy, included with diminishing the environmental load. The building has loaded the environmental impact with GHG's, waste and etc. To quantatify how much affect to the environment by the building over the lifecycle, it required to provide the estimation method. In this paper, it provided the indirect estimation method in aspect of lifecycle energy and CO_(2) of building with input-output table, focused on the construction materials.

본 논문에서는 영상 리타겟팅 방법 중 seam carinvg을 실시간으로 처리할 수 있는 속도 개선 알고리즘을 제 안한다. 기존의 seam carving 방법은 다이나믹 프로그래밍(Dynamic Programming) 기법을 사용하기 때문에 여러 개의 seam을 찾기 위해서는 반복적인 cost 갱신 과정이 필요하다. 제안하는 방법은 이러한 cost 갱신으 로 인한 속도 지연을 개선하기 위하여 누적된 cost에서 seam이 될 수 있는 모든 후보들이 영향을 미치는 영 역을 계산한다. 이를 이용하여 한번의 cost 갱신에서 여러 개의 seam을 추출함으로써 전체 cost의 갱신 횟수 를 줄이기 때문에 전체의 연산 속도가 개선된다. 실험 결과는 제안하는 방법이 빠른 처리 속도와 영상이 가지 고 있는 컨텐츠를 보전하면서 영상의 크기를 조절할 수 있음을 보여준다.

The purpose of this study is to develop optimal prediction model by building prediction models in order to improve systematic risk prediction ability considering the efficiency of security market in Korea. For empirical analysis the data of 111 companies were sampled from January in 1982 to December in 1991. Systematic risk is estimated by means of OLS(Ordinary Least Square)estimation method and added by Bayesian adjusted technique to make systematic risk more stationary. The variables used as accounting information are estimated by making 21 accounting variables in all simple average ranging over selected periods and all applied to the build prediction models. The accounting variables related to Beta and Bayesian are selected by dint of Pearson Correlation and the variables in which multicollinearity lies between explanatory variables are eleminated by means of VIF(variance information factor). This study is produced by multiple regression analysis to make systematic risk be dependent variables and accounting variables be independent ones.Portfolio composed of 3 securities was applied and analyzed by the order of beta size. Also,the suitability of model variables are applied by t-value,R? R?F-value and evaluation criterion of prediction ability by RMSE,MAE,ME,Theil's U. The results of the above study are as follows; As the best model for predicting the systematic risk, ARM Bayesian model in individual level (1-year), ARM Bayesian model in fortfolio level(2-year), Naive Bayesian model in fortfolio level(3-year,4-year),ARM Bayesian model in individual level(5-year) was the best each period. In conclusion, the rick prediction model based only accounting data was not the best over periods. Because the forecasting model over periods is different the forecasting of investment based only accounting data is not desirable for acounting information user's.

This study intends to find and analyze the meaningful factors acting as variables on the foreign policy making of China toward Korea. In this research, domestic and external environments are regarded as influencing on that process. The external environment covers economic, ideological and military condition of China. The internal environments are the China's relations with the United States, Japan and North Korea. China's utmost policy priority can be said to be on the economic modernization. Deng's Pragmatism is also aimed at the development of the economy. The desire to modernize its domestic industry and technology base continues to drive the policies and programs of the Chinese leaders. China is strengthening its military power both in its hardwares and softwares. It may intend to take over the role played before by America and Russia in East Asia, filling the vacuum of power in the region. Communism actually collapsed in world politics. Thus, ideology is becoming less important in international relations. China can not be the exception, so normalized relations with Korea, its probably former ideological enemy. The relationships between China and America and Japan are increasingly economy-based. On the other hand, that with North Korea is losing foundation more and more, as the meaning of ideology diminishes.

The authors investigated the factors influencing drug noncompliance in schizophrenic patients in Yongin Mental Hospital. 37 of 417 schizophrenic patients taking chlorpromazine proved to be drug noncompliant by Forrest urine test. We selected 22 of them who could give reliable answers to self-report questionaire as a noncompliant group. We also selected 22 patients as a control group who proved to be drug compliant by Forrest urine test. Using self-report questionaire we compared the difference in the knowledge about the medication, attitudes concerning the drug, opinions on the therapist-patient relationship and experiences of the drug side effects between two groups. The results were as follows •• 1) The rates of drug noncompliance of 417 patients taking chlorpromazine were 14.5% at the 1st urine test, 21.9% at the 2nd urine test, respectively. 2) The more the dose of chlorpromazine patient takes, the higher was the drug noncompliant rate. 3) The average frequency of medication per day of the drug compliant group was 2,6times per day, which was less than that (2.9 times per day) of the drug noncompliant group. 4) In comparison with the drug noncompliant group, the patients of the drug compliant group showed a tendency to believe that mental hospital teams other than the doctors were more concerned with them. 5) In comparison with the drug noncompliant group, the patients of the drug compliant group showed a tendency to fed more tension when they faced the mental hospital team. 6) The two groups were not signficantly different in their knowledge about the medication, attitudes concerning the drug, and experiences of the drug side effects.

Time domain response analysis for vibro-impact nonlinear behavior of multi-span tube with loose supports was performed using commercial FEA code and user subroutine. Support geometry of multi-span tube with a finite gap is realistically modeled by analytical rigid surface. Model of hydrodynamic force is based on the Qusai-steady model which accounts for the inclined angle of relative flow velocity and time delay between flow force and resulting tube motion. During tube vibration from flow loading, impact and friction at the support location is simulated using commercial FEA code with master slave contact algorithm. Analysis results has reasonable agreement with those of references and test experience. Plan of further refinement of analysis model and future test verification is briefly introduced.

社外理事의 法的地位와 責任

The outside directors system, a means of strong internal control, was obliged for the better corporate governance structure against a weak check on a large stock holder, management and an evil influence-resulted from the self-righteousness of executive. The outside directors system has three types of operation. Which are CEO's voluntary system, organ investors centered system and legal system. Voluntary system lacks independence owing to CEO's appointment of outside directors and legal system has the problem that government does not act as a mediator following the market principles. So the best way to operate outside directors system is as follows. Outside directors should be chosen by agency investors for a small stock holder and other interest group. The outside directors' legal status remains only a member of board of directors according to Korean law. In addition to this, outside directors are a party to the trade, the third control organ and creditor directors that banking facilities sent in terms of law. They have power as directors in company law, fiduciary duty, notice obligation and other concrete duties like safekeeping secrets and protection of organ investors and a small stock holder. Because of outside directors' inferior management speciality and expert knowledge to inside directors, the reduction of responsibility was on the rise due to the theory of case law. But there were problems and a majority opinion is the equal responsibility principle in the academic world because they are the members of same board of directors. But it is not deniable that they were for the check on management and the prevention of interest group's damage. So their duty as a management guard should linked to the augmentation of their responsibility. When role duplicators, outside auditor and auditor, are members of audit committee, the responsibility of outside director, non committee member, is the point in question. Non committee members require to pay attention as much as a man with reasonable, general prudence, professional knowledge and technology do for himself in similar business area. So outside directors, although non committee member, must be responsible. Outside director system itself causes no legal problems but audit committee consists of outside directors will overlap with auditor, a standing organ, and outside auditor's role. At this time, audit committee is only a american management organization under board of directors, so the introduction of this system must be considered carefully because the control method of organ, features of Korean company law, may fade away.
