The purpose of this study is to analyze the influence of the number of investors influencing the achievement rate of domestic securities type crowdfunding, to find out why the general investors need to participate and to suggest measures to increase the participation of general investors. The results of this study are as follows. First, the effect of the recruitment amount, the target amount, the recruitment period and the business training is confirmed as factors affecting the achievement rate of domestic securities type crowdfunding. And it was confirmed that the influence factors on achievement rate could have a greater effect as the number of general investors increased. Therefore, the government should make more effort to relax regulations on general investors, and the investor of capital should strengthen the public disclosure of KSM through the KSM market in order to recover the funds of general investors, Crowd funding will be able to attract enough funds.

The purpose of this study is to present the direction of ELS investment by analyzing the actual investment return of the ELS commodities and analyzing the investment effect of ELS that investors have felt unsatisfactory at financial marketing service. The research method is based on the step-down type ELS. We calculated the probability of achieving early redemption condition and maturity repayment condition, early redemption estimated yield, and maturity repayment estimated yield. As the study result, the probability of achieving 100% of the early redemption condition was 74.5%, and the probability of the early redemption condition 95% was 83.0%, 90% was 89.5%, 85% was 92.5%, and 80% was 96.5% respectively. In the case of the lowest 75%, the probability of holding to maturity is analyzed to be 2.5%, and the probability of early redemption is high. The probability of the stock price growth within 65% of the maturity repayment condition was 98.5% and the probability of the stock price growth within 60%~45% of the maturity repayment condition was 100%. 65% of maturity repayment condition was analyzed as 1.5% risk of principal loss, and the probability of achieving the committed yield of maturity was high. As a key measure of ELS investment, it is advantageous to select a commodity with a low rate of maturity repayment and a high rate of early redemption.

Recently, crowdfunding platforms have received attention as one of the content investment platforms for the public. This research attempts to explore the influencing factors on the success of movie euqity crowdfunding project. We use 'number of texts', 'number of images', 'star influence power', 'IP-based movie project', 'movie production stage', 'box office prediction', 'investment capital ratio', 'amount of surplus available investment', 'profit calculation method' and 'minimum investment amount' as independent variables. And we examined how these factors affects the achievement rate of movie crowdfunding. As a result of multiple regression analysis, 'movie production stage', 'investment capital ratio', 'amount of surplus available investment' and 'profit calculation method' have a significant effect on the crowdfunding achievement rate. In addition, the results of this research can be used for reference when planning film crowdfunding projects.

This study aims to find out success factors of crowdfunding on movie projects. For empirical analysis, we collected 583 data of the movie projects from the crowdfunding platform 'Tumblbug'. To figure out the success factors, we examined effects of 10 independent variables on 1 dependent variable. The independent variable includes target amount, project information, reward options, creator funding power, editor recommendation, creator contents power, movie type, number of comments, number of replies, and number of SNS information. The final achievement rate of crowdfunding was set as dependent variable. This study found that the target amount, number of text information, number of video information, editor recommendation, number of backers' reply, and number of SNS information had a significant impact on the achievement rate of the movie crowdfunding project. This study has implications in that it has discovered a variable of editor recommendation and the number of SNS information, and both of them have a positive effect on crowdfunding achievement.

This study was implemented to verify the validity and effectiveness of the current evaluation indicators by analyzing the content and result of the current survey for evaluating a small library, based on the achievement rate of each index. To this end, questions, included in evaluation indices for the small library were reviewed, and survey data from a total of 19,476 libraries during the past 3 years from 2018 to 2020 were investigated to analyze the evaluation scores, differences and achievement rates of each item. It was proposed to delete or add some indicators of the current evaluation category, and to raise supplementally the need for qualitative assesment. Based on the research results, the following implications are suggested. First of all, the evaluation of small libraries should focus on the quality of the services they provide rather than the library environment. Second, demonstrable systematic indicators should be designed and then clearly explained to resolve the ambiguity of the terms used. Third, for better analysis, it is necessary to distinguish evaluation items between public and private small libraries and the assessment process should be done by the local government. Lastly, qualitative evaluation items that can measure users' satisfaction should be added.

기존의 고정 중계를 하는 협력 통신 프로토콜은 중계기가 언제나 신호를 보내기 때문에 전송률이 높은 경우에는 비효율적이다[1]. 그러므로 수신단이 요구하는 경우에만 중계기가 신호를 송신하는 협력 재전송 프로토콜이 제안 되었다. 본고에서는 다양한 협력 재전송 프로토콜을 소개하고 송신단이 각 링크의 평균 신호대 잡음비만 아는 경우의 프로토콜들의 달성 가능 전송률을 비교한다. 또한, 전송 횟수에 제한이 없는 경우에 각 협력 재전송 프로토콜의 에르고딕 전송용량 달성 여부를 알아본다.

2018년 물관리 일원화를 위한 정부조직법 개정으로 기존 국토교통부의 「수자원의 조사·계획 및 관리에 관한 법률」 등의 사무가 환경부로 이관되었다. 과거 부처별로 나누어진 물 관리 체계에 따라 부처간 업무중복, 과잉투자 등 수량과 수질에 대한 분리된 관리체계의 한계점으로 유역 상류에 설치된 댐의 경우 저류된 댐 용수의 수질악화의 문제가 발생하였다. 또한, 물관리 일원화 이후, 「제2차 물환경관리 기본계획」에서는 2025년까지 주요 상수원 수질을 좋음(I)등급 달성을 목표로 제시하였고, 이와 연계하여 평가지표 등에 설정한 댐 수질목표를 2025년까지 매우좋음(Ia) 등급 달성을 위해서는 댐 상류 주요 오염원에 대한 과학적 분석이 필요하며 이에 대한 관리대책 마련이 시급한 상황이다. 본 연구의 공간적 범위인 사연댐은 울산공업지구의 공업용수 확보를 위해 1965년 준공되어 울산 일원에 100,000m³/일 이상의 공업용수를 공급하는 수원시설이며, 대곡댐은 기존 울산지역에 공업용수로 사용하던 사연댐의 물을 생활용수로 전환하고, 대곡·사역댐의 연계운영을 통해 연간 66백만의 생활용수를 공급하기 위한 수원시설이다. 수질 목표기준의 경우 대곡댐은 좋음(Ib), 사연댐은 매우좋음(Ia)로 설정되어 있으나, 2015~2019년까지의 TOC, T-P의 평균 달성률을 살펴보면 대곡댐은 TOC 45.8%, T-P 27.1%의 목표수질 달성률을 나타내었고, 사연댐은 TOC 및 T-P 모두 0%로 목표수질을 달성하지 못한 것으로 조사되었다. 본 연구에서는 대곡·사연댐 상류 유역을 대상으로 유역의 특성 및 오염원 발생 특성을 파악하고, 이에 따른 물환경관리 종합대책을 수립하기 위하여 1) 유역 물환경 기초자료 조사와, 2) 모니터링을 통한 댐유역 오염 원인분석을 수행하였다. 그 결과를 바탕으로 소유역별 오염부하량을 분석하고 개선대책(안)을 도출하였다. 이 때, 개선대책의 효과를 분석하기 위해서 유역 모형(HSPF)과 호소수질(AEM3D) 모형을 활용하여 수질모델 구축 및 보정을 수행하였고, 개선 대책(안)에 대한 목표수질 달성여부를 파악하였다. 최종적으로 대곡·사연댐 유역의 호소수질 변화를 파악하고 댐 유역 특성을 고려한 맞춤형 물환경관리 종합대책을 제시하였다.
