최근 크라우드 펀딩 시장의 높은 성장률과 장점으로 인해 브랜드와 기업의 참여가 증가하고 있으며 이는 패션 비즈니스에도 예외가 아니다. 특히 온라인 플랫폼을 기반으로 한 크라우드펀딩 상황에서 서포터가 실제 제품을 받기 전에 전액을 지불해야 하며 소비자의 지각된 위험은 소비자 구매의사결정에 핵심적인 영향을 미치는 요인으로 작용한다. 따라서 온라인 플랫폼을 기반으로 하는 크라우드펀딩의 인지된 위험을 높이거나 억제하는 플랫폼 환경, 소비자 개인 특성, 또는 프로젝트의 구성 요인에 대한 심화된 연구가 필요하다. 한편 크라우드펀딩에서 인지된 위험과 소비자 태도에 대한 과거 문헌은 확장되었지만 패션 제품과 같은 경험재 소비와 관련된 맥락에서 플랫폼과 프로젝트의 특성에 관해 다룬 연구는 매우 드물었다. 따라서 본 연구는 패션 크라우드 펀딩 프로젝트에서 제공되는 지각된 정보의 양이 지각된 위험과 프로젝트 참여 의도에 미치는 영향을 실증적으로 분석했다. 가설을 검증하기 위해 총240명의 한국인 참가자를 대상으로 한 설문조사를 실시했고, 본 연구의 실험을 위해 가상의 패션제품 크라우드펀딩 페이지를 자극물으로 설정하였다. 데이터를 분석한 결과, 패션 크라우드펀딩 프로젝트에 대한 지각된 정보의 양이 많은 상황에서 적은 상황에 비해 응답자들의 프로젝트에 대한 참여의도가 높았다. 또한 지각된 정보의 양은 소비자의 지각된 위험에 부적인 유의한 영향을 미쳤다. 또한 지각된 위험은 참여의도에 부적인 유의한 영향을 미쳤다. 마지막으로 지각된 위험은 지각된 정보의 양과 프로젝트 참여의도 사이의 관계에서 부분 매개효과를 가졌다. 연구결과를 바탕으로 한학술적 실무적 의의 및 연구 제한점이 논의되었다.

The purpose of this study was to determine the relationship between company risk and factors such as business size, ownership structure, and leverage. The study was conducted on 142 manufacturing sector companies listed on the Indonesia Stock Exchange from 2013 to 2018. The purposive sampling method was used to select the research sample. The sample size for this study was 21 different companies. The analytical approach uses Structural Equation Modeling (SEM) with WarpPLS. According to the findings of the investigation, the size of the company has a significant influence on both the amount of leverage the company uses and the amount of risk the company takes. The level of leverage is significantly influenced by the ownership structure. However, the ownership structure does not have a significant impact on the level of risk the company; rather, leverage has a big impact on the level of risk the company faces. The findings of this study are helpful to prospective investors in measuring the risk posed by the company to make judgments regarding investments. The findings of this study are also essential for management to consider while controlling the risk of the organization.

In order to investigate dietary risk factors for hypertension in th elderly, dietary intakes and dietary habits of 405 elderly subjects, aged 60-94, were assessed by the questionnaire, anthropometric measurement and a 24-hour dietary recall. The prevalence of definite (>95mmHg for diastolic or>160mmHg for systeolic blood pressue) and borderline(90-95mmHg for diastolic or 140-160mmHg for systolic blood pressure) hypertensive subjects 33.3% and 19.3%, respectively. The distribution of the subjects for Body Mass Index(BMI), waist-hip ratio, and alcohol consumption were significantly different among definite, borderline, and normal groups(p<0.05). The distribution of the subjects for smoking, exercise, and preference of salty food were not significantly different among definite, borderline, and normal groups(p>0.05). From the generalized logistic regression analysis of the risk factors for the hypertension, the subjects with over 27 of BMI had significantly higher risk of hypertension. Alcohol consumption and preference of salty food were significant risk factors of hypertension in the elderly. Dietary risk factors for the hypertension that had significant relationship to the hypertension were intakes of potassium, calcium, phosphate, sodium, vitamin B1, niacin, and folate. There was no significant difference of consumption frequencies of food and dish among definite, borderline, and normal groups(p>0.05). The amount of intakes for cereals and grain product, bean and their products, eggs were significantly different among definite, borderline, and normal groups(p<0.05). In summary, the amount of dietary intakes to hypertension in elderly population. Longitudinal studies for dietary risk factors on incidence of hypertension are needed in general population, especially in the elderly.

This review addresses the role of fat in beef palatability and healthfulness. Particular emphasis is placed on the content of oleic acid in beef, and how this increases with time when cattle are fed a grain-based diet. Oleic acid decreases the melting point of lipids from beef, increasing the perception of juiciness and improving beef flavor. Clinical trials have demonstrated that ground beef containing elevated oleic acid increases, or at the least has no negative effects on the concentration of HDL cholesterol. The amount of fat in published ground beef intervention trials greatly exceeds the amount of fat in equivalent portions of beef from U.S. domestic or Korean Hanwoo cattle. Thus, we conclude 1) Beef cattle should be raised under production conditions that increase the concentration of oleic acid in their edible tissues (i.e., by grain feeding over extended periods of time); and 2) The amount of fat consumed in a typical portion of beef will not increase risk factors for cardiovascular disease.

There have been various studies on measurements of flood risk and forecasting models. For river and dam region, PDF and FVI has been proposed for measurement of flood risk and regression models have been applied for forecasting model. For Bo region unlikely river or dam region, flood risk would unexpectedly increase due to outgoing water to keep water amount under the designated risk level even the drain system could hardly manage the water amount. GFI and general linear model was proposed for flood risk measurement and forecasting model. In this paper, FVI with the consideration of duration on GFI was proposed for flood risk measurement at Bo region. General linear model was applied to the empirical data from Bo region of Nadong river to derive the forecasting model of FVI at three different values of Base High Level, 2m, 2.5m and 3m. The significant predictor variables on the target variable, FVI were as follows: ground water level based on sea level with negative effect, difference between ground altitude of ground water and river level with negative effect, and difference between ground water level and river level after Bo water being filled with positive sign for quantitative variables. And for qualitative variable, effective soil depth and ground soil type were significant for FVI.

Purpose: In many Korean hospitals, serum acetaminophen concentrations in cases of overdose cannot be measured initially because of inadequate laboratory facilities. Under these circumstances, physicians base the administration of the antidote, N-acetylcysteine, on ingestion amounts as determined by initial history taking. We therefore examined the correlated between ingested amounts and serum acetaminophen concentrations. Methods: Medical records were reviewed retrospectively for patients who presented to the ED with acetaminophen overdose between January 2002 and March 2006. Fifty-nine patients were recruited and sixteen patients were excluded. The forty-three remaining patients were placed into either the high-risk or low-risk group based on their ingested amount (140 mg/kg), and were separately categorized into the toxic or non-toxic group based on their serum acetaminophen concentrations, according to the Rurnack-Matthew nomogram. Results: Ten patients (83.3%) among twelve in the high-risk group were found to have non-toxic serum concentrations, and just one patient (3.2%) among thirty-one in the low-risk group fell into the toxic group based on their serum concentrations. The sensitivity and specificity of risk stratification of the ingested amount as a predictor of intoxication requiring antidote therapy were 66.7% and 75.0%, respectively. Conclusion: This study suggests that the therapeutic decision for acetaminophen overdose should not be based solely on ingested amount only, but requires assessment of acetaminophen concentration.

This study was performed to investigate the relationship between obesity, health-related lifestyle, and dietary intake and serum lipid level in 96 male university students. Health-related lifestyle factors were obtained from questionnaires. Dietary intakes were evaluated with one-day 24-hr recall and two-day dietary record. Anthoropometric data were recorded and serum cholesterol and triacylglycerol concentrations were measured. 21.9%, 36.5%, 36.5%, and 6.2% of the subjects had levels beyond the normal range in serum total cholesterol(TC), HDL-cholesterol(HDL-C), LDL-cholesterol(LDL-C), and triacyglycerol respectively, and 57.3% of the subjects had more than one hyperlipidemic factor. TC was correlated positively with BMI(p〈0.01), waist length(p〈0.05), hip length(p〈0.05), and the amount of smoking(p〈0.05). HDL-C was correlated negatively with BMI(p〈0.05) and hip lenghth(p〈0.05). LTD-C was correlated positively with BMI(p〈0.01), water length(p〈0.05), hip length(p〈0.01), and coffee consumption(p〈0.05). TG was correlated positively with waist length(p〈0.01), waist-to-hip ratio(p〈0.05), and amount of smoking(p〈0.01) and negatively correlated with frequence of exercise(p〈0.05). Among nutrient intakes, only the ratio of protein to energy was correlated negatively with TC(p〈0.05). Logistic regression analysis revealed that BMI, waist length, hip length, waist-to-hip ratio, and amount of cigarette smoking were associated with an increased risk of hyper-TC. BMI, waist length, and hip length were associated with an increased risk of hypo-HDL-C. BMI and coffee consumption were associated with an increased risk of hyper-LDL-C. Amount of cigarette smoking was associated with an increased risk of hyper-TG. In conclusion, a high prevalence of hyperlipidemia in subjects was observed. Also obesity, smoking, and coffee consumption were observed to be highly with the risk of hyperlipidemia in subjects. These findings imply that these factors should be primarily considered in planing the nutrition education program for the prevention of cardiovascular disease in male university students.

In this paper, we consider a diffusion risk process, in which, its surplus process behaves like a Brownian motion in-between adjacent epochs of claims. We assume that the claims occur following a Poisson process and their sizes are independent and exponentially distributed with the same intensity. Our main goal is to derive the exact formula of the joint moment generating function of the ruin time and the total amount of aggregated claim sizes until ruin in the diffusion risk process. We also provide a method for computing the related first and second moments using the joint moment generating function and the augmented matrix exponential function.

In this paper, we show that there exists an optimal investment policy for the surplus in a risk model, in which the surplus is continuously invested to other business at a constant rate a > 0, whenever the level of the surplus exceeds a given threshold V > 0. We assign, to the risk model, two costs, the penalty per unit time while the level of the surplus being under V > 0 and the opportunity cost per unit time by keeping a unit amount of the surplus. After calculating the long-run average cost per unit time, we show that there exists an optimal investment rate $a^*$>0 which minimizes the long-run average cost per unit time, when the claim amount follows an exponential distribution.
