이국형,이준희,김정준,김영곤,Lee, Kuk Hyung,Lee, Jun-Hee,Kim, Jeong-Joon,Kim, Young-Gon 한국인터넷방송통신학회 2018 한국인터넷방송통신학회 논문지 Vol.18 No.1
최근 웰빙(Well-Bing) 열품에 힘입어 화학적으로 가공되지 않은 천연 식품을 찾는 소비 형태가 많이 부각되고 있다. 하지만 현대 시대를 살아감에 있어 화학 식품 첨가물이 포함되지 않은 식품을 주변에서 찾기는 매우 힘들다. 또한 가공 조리된 식품에는 화학 식품 첨가물의 성분이 제대로 표기되어 있지 않거나 표기가 생략되어 나오는 제품이 상당수다. 본 논문은 한국의 연간 화학 식품 첨가물 소비량 데이터를 기반으로 첨가물 별 대두 되고 있는 암 발생을 빅 데이터 분석 기법 중 하나인 시계열 분석과 회귀 분석을 통해 검증 할 것이며, 이러한 식품 첨가물이 사회의 어떠한 요인 때문에 소비가 증가했는지에 대한 빅 데이터 분석을 실시해 검증한다. Well-Bing Many consumer forms of natural foods that are not chemically processed due to heat are becoming popular. However, it is very difficult to find foods that do not contain chemical food additives in the modern. Also, there are many products that do not have proper marking of ingredients of chemical food additives or are omitted from marking. Based on the annual data on chemical food additive consumption in Korea, this paper will examine the occurrence of cancer, which is emerging by additives, through time series analysis and regression analysis, one of the big data analysis techniques. Of the total population.

This study aims to analyze the ideas of whether the financial institutions would accept easing credit-enhancement (typically in the form of guarantees) requirements on real estate project finance (PF) loans; if they accept whether they would participate in PF loans with these eased requirements; and if they participate in these PF loans which factors they would consider. Statistical methods have been applied and AMOS 19.0 and SPSS 12.0 in particular were used in this analysis. The statistical population was 281 relevant professionals working at 41 financial institutions. Effectively 150 completed surveys have been collected and analyzed-172 completed surveys have been collected, 22 of which were discarded because they were unsuitable for analysis. The potential variables of this research model, based on choice factors of behavior, were taken as follows: ⅰ) the perception of real estate PF lending; ⅱ) the need of easing credit-enhancement; ⅲ) the implementation level of real estate PF; ⅳ) the receptiveness of easing credit-enhancement approaches; and ⅴ) the possibility of project participation from financial institutions. The research results are the following. First, the financial institutions appreciate the notional reason that risk should be shared among real estate PF participants and the ongoing change of credit-enhancement environment provided by construction companies. Therefore easing credit-enhancement requirements is necessary, and financial institutions are reviewing corresponding solutions in taking risks related to PF loans. Second, financial institutions are raising the following conditions for future projects they would consider for PF lending: ⅰ) projects where a third-party shares construction completion risk by lending against the construction cost; ⅱ) joint venture projects with land owners or projects of which the PF amounts are small owing to increased equity contribution from the real estate developer. This attitude of the financial institutions implies that they will participate in PF lending passively and in limited scale compared to the past should the credit-enhancement becomes eased.

The purpose of this study is to categorize the credit granting on real estate project financing by construction companies and define the characteristics. The credit granting of construction companies are categorized by restricted sense, broad sense, supra-broad sense. Based on the categorization the characteristics of credit granting on 73 project financing business are analyzed. The results of this research are as follows: First, the construction companies with low credits are participating in real estate project financing enduring the risk of credit granting frequency. Second, the most common credit granting method of construction companies are joint liability on guarantee. This reflects the convenience of collecting PF debenture of financial companies. Third, the companies with high credit rate have more credit granting on banking sector and the apartment projects. This shows that the companies with higher credit ratings have competitiveness on financing cost and also the social phenomenon of apartmentbranding. Forth, there was difference in project risk management depending on the credit rate of the construction companies. The companies with low credit rate are participating in retail projects with savings bank project financing which have more risk of project due to the project delays. This study can be applied as a basic data and also suggest a way out for the real estate project financing sector which has come to a standstill by global economic crisis and the suspension of business of savings bank.
