Horticultural facility farmers subscribe to crop accident insurance and insurance products secured by horticultural facilities in preparation for possible risks in the facility. Insurance is purchased to prepare for natural disasters such as typhoons, hail, frostbite, heavy rain, and strong wind damage covered by the product. In order to find out the effect of risk perception, which is a subjective perception of the risks of a given situation, on horticultural facility farmers' intention to purchase horticultural facility insurance products, the risk perception and insurance purchase intention were analyzed. A t-test was conducted to determine the impact relationship between farm size, insurance coverage, and risk perception, and multiple regression analysis was conducted to verify the effect of personal characteristics and behavioral factors such as subjective perception, reference group, media exposure, and compensation understanding. In addition, a three-step regression analysis by Baron & Kenny was conducted to confirm the mediating role of personal characteristics and behavioral factors in the relationship between risk perception and insurance purchase intention. As a result of the study, although there was no difference in farm size, it was analyzed that policy holders had a higher degree of risk perception than non-subscribers, and that compensation understanding had the greatest influence and subjective knowledge had the smallest influence. In addition, these four factors were verified to have a mediating effect on the relationship between risk perception and insurance purchase intention. These results are expected to provide practical help to the development and marketing activities of horticultural facility insurance products.

The purpose of this study is to verify the factors that affect the fear of crime by applying the risk interpretation model. Especially, whereas previous studies have not proven micro individual factor that the risk interpretation model had presented, This study includes micro individual elements such as neighborhood factor, perceived risk of crime, fears of crime as main variables. This study utilized secondary data of the National Crime Victimization Survey 2012, conducted by the Korean Institute of Criminology. In this study, multiple regression analysis of two stages and Sobel Test were conducted for verifying the individual influence of each independent variables and identifying the causal relationship between the variables set out in the risk analysis model. As the result, it appeared that the higher level of perceived risk of crime, neighborhood factor, crime experience, education, income cause the higher degree of the fear of crime. On the other hand, the lower degree of age was found to induce the higher level of the fear of crime. In addition, female showed the higher degree of the fear of crime than man. The causal relationship between the variables set out in the risk interpretation model was presented significantly in all variables, except for education.

Recently, a research of the urban regeneration has been performed very actively. This is one of the efforts to resolve various social and economic problems coming from the existing deteriorated building and facilities by new urban development or redevelopment. However, an urban regeneration has a characteristic to be unable to ensure the project performance due to the exposed numerous risks coming from the various and complex stake-holders, and its mega sizes. This paper proposes the method of risk performance index in order to improve an efficiency of performance measurement expanding to the risk view point from the existing integrated cost/schedule performance measurement. A risk performance index is compatible with the existing EVMS, and can make the performance measurement in 3 dimensions of the integrated cost/schedule/risk with 18 sub-indexes and variables.

This study is aimed to examine effects of sociodemographic, social relation, and health related factors on risky drinking among early, middle, and older adulthoods. Using the sixth(2013-2016) National Health and Nutrition Examination Survey, separate logistic regression analyses were conducted for women's early adulthood (n=1,143), middle adulthood (n=1,306), and older adulthood (n=875) to test factors associated with risky drinking. For study results, as for women's early adulthood, education, marital status, employment, depressive feeling, and smoking were statistically associated with risky drinking. As for women's middle adulthood, only subjective stress level and smoking were associated with risky drinking. As for women's older adulthood, education, suicidal ideation, and subjective health condition were associated with risky drinking. These results found different factors influenced risky drinking according to life stages. Based on these results, convergent implications about reducing risky drinking according to life stages of women were discussed.

One of the methods of securing the reliability of accounting information is maintaining high audit quality. The first step of improving audit quality is lowering audit engagement risks. Thus, this study analyzed the relationship between the characteristics of accounting firms and audit engagement risks based on the Bayesian Network. For this, Markov Blanket, the minimum explanatory variable set, which affects audit engagement risks, was presented, and based on the drawn causal relationship, sensitivity analysis was conducted to verify the characteristics of accounting firms, which affect audit engagement risks. The existing preceding research that used multiple regression analysis presumes the linearity between explanatory variables and dependent variables, so there was a limit in drawing the relationship between explanatory variables. Therefore, this study figured out the interdependence between variables using the General Bayesian Network and examined the impact that each variable has finally on audit engagement risks that affects the audit quality. The results of this study would greatly contribute to improving the efficiency of the supervisory task by allowing a supervisory institution to identify an accounting firms that does not manage audit engagement risks properly and to improve the supervision of the accounting firms in advance. In addition, this study will be used as a reference when a supervisory institution would improve the system related to audit quality by presenting the characteristics of accounting firms related to the audit quality.

The objective of this empirical study is to examine the mediating and moderating effects of perceived risks on the relationship between knowledge, feelings and acceptance intention towards AI. Subjects in their teens to forties were surveyed and the final sample comprised 1,969 subjects. Data were analyzed using Mediation using Multiple Regression and Moderated Multiple Regression. Results showed that people's knowledge and feelings towards AI affected their acceptance intention of AI. Results also showed that the perceived risks of AI partially mediated and moderated the relationship between feelings and acceptance intention towards AI and moderated but not mediated the relationship between knowledge and acceptance intention towards AI. Overall, these results suggest that people's perceived risks of AI are associated more strongly with their feelings towards AI than their knowledge towards AI. Implications and directions for future research were discussed in relation to increasing general population's acceptance intention towards AI.

We This study aimed to quantitatively analyze the theme of 'libertinage' and the associated issues of reason and emotion in 『Dangerous Liaisons』, a novel considered a masterpiece of libertine literature and an epistolary novel of the 18th century, using digital analysis tools. First, based on the frequency analysis of word usage using Voyant and LIWC 22, we confirmed that libertinage is manifested with keywords such as 'love' and 'time'. With Voyant's 'Contexts' feature, it was found that the letters sent by Valmont to Madame de Tourvel and those sent by Madame de Merteuil both have 'love' as the central theme. However, emotional vocabulary was higher in the former, whereas strategic vocabulary was more prevalent in the latter. Additionally, it was observed that the most frequently used word in the letters sent by Madame de Merteuil is 'time', with a higher frequency than 'love'. Thirdly, using LIWC 22, we measured the analytical thinking and emotional tone of the letters exchanged by the main characters, and analyzed how these values changed according to the chapters. Through these analyses, we confirmed that this novel, alongside Rousseau's "New Eloise," anticipates romanticism by embracing the theme of 'emotion,' which was rejected by 18th-century Enlightenment ideals.

본(本) 연구(硏究)는 자본거래자유화정도를 명목상의 규제완화여부에 의해 판별하는 종래의 접근방법(接近方法)에서 벗어나, 형식적(形式的) 규제여부(規制與否)에 관계없이 자본거래(資本去來)가 실질적으로 경제적(經濟的) 유인(誘引)에 따라 얼마나 활발하게 이루어지고 있는가를 측정함으로써 자본거래자유화정도(資本去來自由化程度)를 평가할 수 있는 방법을 모색하고 있다. 이와 관련해서 본 연구는 모두 5가지 접근방법을 시도하고 있다. 그 첫째는, 총대외무역량대비 자본거래량비중으로서 자본거래량이 상대적으로 증가하면 자본거래자유화정도가 높다고 본다. 둘째는, 환율절하기대를 감안한 국내외실질 금리차로서 대내외자본거래(對內外資本去來)가 자유로울수록 국내외금리차(國內外金利差)는 낮아질 것이기 때문에, 동 금리차가 낮을수록 자본자유화정도가 높다고 본다. 동 지수로서는 통화선물시장의 존재 여부에 따라 위험포함 및 불포함 대내외금리차를 사용할 수 있다. 셋째로는, 다소 복잡한 계량경제학적 방법을 통해 국내외실질금리간의 연계관계를 측정하는 방법으로서 두번째 방법의 개선에 해당된다. 그리고 넷째로는, 셋째번 방법에 의한 연계관계를 시간변동지수로 전환하여, 시간의 경과에 따른 자본자유화정도의 변화를 측정하고 있다. 마지막으로는, 자본거래를 위험자산의 국제교역관계(國際交易關係)로 파악하여, 무역에 있어서의 산업내교역지수측정방법을 자본거래에 적용하여 자본거래총유출입지수를 측정하였다. 동 지수는 저축투자갭의 보정적(補正的) 거래차원을 넘어 위험자산거래 자체를 위한 자본거래의 정도를 측정함으로써 순수하게 자본거래 자체의 메커니즘에 의해 자생적으로 일어나는 자본거래의 활성화정도에 대한 척도가 될 수 있을 것으로 판단된다. 이상의 방법들을 주로 한국(韓國), 일본(日本), 대만(臺灣) 등에 적용해서 평가한 결과 한국의 자본거래자유화정도(資本去來自由化程度)는 일본에 비해서는 낮지만 대만에 비해서는 높으며, 특히 90년대 들어 크게 향상된 것으로 평가되었다.

자본시장에서 자산가격결정이론의 대부분은 투자자산의 기대수익률과 변동성이 시간의 흐름에 따라 일정한 것으로 가정하여 왔다. 그러나 최근의 연구 성과에 의하면 주식수익률의 변동성이 동분산이라기 보다는 이분산일 가능성이 높다는 것이다. 1982년 Engle에 의하여 개발된 자기회귀 조건부 이분산모형(ARCH)이 제시된 이래 ARCH형태의 모형개발이 계속 이루어져 왔다. 본 논문은 ARCH형태의 이분산모형 가운데서 EGARCH모형을 이용하여 위험프레미엄과 조건부 이분산과의 관계와 더불어 기대하지 않은 수익률변화와 변동성과의 관계를 규명하고자 노력하였다. 1980년에서 1994년까지의 주가자료를 전체기간과 세부기간(4기간)으로 분류하여 기술 통계량 분석을 행하고, 종합주가지수초과수익률, 동일 가치 가중지수초과수익률, 대형주 주가지수초과수익률, 소형주 주가지수초과수익률에 대하여 EGARCH모형 을 적용하여 실증분석 하였다. 그 결과 위험프레미엄과 조건부 이분산은 시간이 지남에 따라 일정한 관계를 보여주지 못하고 있어 투자자의 위험회피도(危險回避度)가 변화함을 보여주었다. 기대하지 않은 수익률변화와 변동성 관계에서는 기대하지 않은 음(陰)(-)의 주식수익률이 기대하지 않은 양(陽)(+)의 주식수익률보다 상대적으로 더 큰 변동성을 가져오는 것으로 보여 우리나라 주식시장에서 주식수익률의 변동성 정보의 비대칭 반응효과가 존재하는 것으로 나타났다.

본 논문에서는 자본시장의 변동성을 충분히 해명할 수 있는 가격결정모형이 정립되었다. 자본 자산의 가격은 세개의 위험에 대한 프리미엄의 총화임이 도출되었다. 이 세개 위험은 소비베타와 유사한 형태를 갖는 모수, 시장베타와 유사한 형태의 모수, 그리고 총국민생산의 성장률과 자산과의 공분산에 의하여 정의되는 모수이다. 이 모수를 각각 소비위험모수, 시장위험모수 및 생산위험모수라 할 수 있다. 자산의 가격을 결정하기 위하여 가격화(pricing)되는 체계적 위험이 세개라는 것은 중요한 함의인 것이다. 자산의 가격은 소비와 시장에 의하여 결정된다. 소비와 시장은 자체의 독립적 영역과 서로 상대에 대하여 상호작용하는 영역을 갖는다. 독립적 영역에서 생성되는 위험이 소비모수와 시장모수로 표상되며, 이 양자의 상호작용관계가 생산모수로 귀일한다.
