        The content of harmful materials was investigated for coffee beans sold in Daejeon. Total 79 samples were analysed and 213 residual pesticides and 2 heavy metals were analysed simultaneously by GC-MS/MS, GC-NPD, GC-ECD, LC-MS/MS and ICP-MS. The instrumental method was validated with limit of detection (LOD), limit of quantification (LOQ), the linearity of standard curves. LOD of the residual pesticides was between 0.0003 to 0.0021 mg/kg, LOQ of the residual pesticides was between 0.0008 to 0.0064 mg/kg. LOD of the heavy metals was between 0.0077 to 0.0079 μg/kg, LOQ of the heavy metals was between 0.0233 to 0.0239 μg/kg. The linearity correlation coefficient for the calibration curve was between 0.9929 to 0.9999 and the recovery rate was between 95.4% to 106.1%. According to the monitoring of residual pesticides and heavy metals, no pesticide was detected in all coffee bean samples. 88.6% (70 samples) of analysed total 79 coffee beans contained at least 1 heavy metal but there was no sample which exceeded the maximum residual limit. Risk assessment was also carried out based on the content of heavy metals detected in coffee beans. The carcinogenic risk assessment to heavy metals showed that all cancer-risk (CR) values were below 10–6 and it meant that the CR due to heavy metals intake was evaluated as safe. The non-carcinogenic risk assessment to heavy metals showed that all hazard index (HI) were below 1, which was considered acceptable at the current level of exposure. The %PTWI values of lead and cadmium for 55 roasted coffee bean samples were 0.09% and 0.04% respectively, compared with the reference values. This results indicate that there is almost no health risk from heavy metal intake through the consumption of coffee beans in circulation in Daejeon.

        포인트 클라우드를 활용한 폴리곤 모델 활용에 대해서는 지속적으로 연구되고있다. 이러한 연구는 대부분 하이 폴리곤 모델을 대상으로 생성된 모델을 활용한 기술이다. 오늘날 비디오 게임 등에서 활용되는 하이 폴리곤 모델은 대부분 높은 퍼포먼스를 바탕으로 화려한 효과를 표현한다. 그러나 게임 등의 콘텐츠에 있어서 화려한 효과와 높은 품질의 리소스를 활용한 게임만이 만족도를 충족시켜주는 것이 아니다. 콘텐츠에 따라서 의도적으로 로우 폴리곤 모델을 활용하기도 한다. 인디 게임 등에서는 낮은 접근성을 장점으로 로우 폴리곤 형태의 모델을 제작하여 이를 활용한 게임들도 지속적으로 개발되어 왔다. 따라서 본 연구에서는 이러한 변화에 맞춰서 포인트 클라우드 데이터를 활용하여 로우 폴리곤 모델을 생성 및 음영 처리하는 방법을 제안한다. 여러 개의 모델을 생성하여, 각각의 모델이 하나의 텍스처를 공유하고, 음영을 처리한다. 마지막으로 라이트맵 기법의 결과물과 비교하는 실험을 진행한다.

        사용자들이 게임의 기능적 편리성뿐만 아니라 정서적 충족을 목표로 하면서, 이러한 점을 고려한 새로운 감성공학이 게임산업에 적용되었다. 이러한 이유로 게임업계에서도 게이머의 정서적 충족을 목표로 게임을 개발하려는 움직임이 활발하다. 따라서 게임이 출시 전 개발단계에서 감성평가라는 제도가 적용되었다. 감성평가는 게임 인터페이스와 시스템, 게이머의 감성적 욕구 등을 평가하는 방식이다. 다만 평가방식이 평가자의 주관에 따라 결정되는 단점이 있다. 그래서 게이머의 몰입여부에 따라 답변이 달라질 수 있는 문제를 가지고 있다. 따라서 본 연구에서는, 아이트래킹 기술과 본 논문에서 제시한 평가 시스템을 이용해 게이머의 몰입도를 측정하고, 그 후 감성평가를 실시함으로써 감성평가의 신뢰성을 높이는 방법을 제안한다.

        This study proposes a method of separating uranium (U) and minor actinides from rare earth (RE) elements in the LiCl-KCl salt system. Several RE metals were used to reduce UCl3 and MgCl2 from the eutectic LiCl-KCl salt systems. Five experiments were performed on drawdown U and plutonium (Pu) surrogate elements from RECl3-enriched LiCl-KCl salt systems at 773 K. Via the introduction of RE metals into the salt system, it was observed that the UCl3 concentration can be lowered below 100 ppm. In addition, UCl3 was reduced into a powdery form that easily settled at the bottom and was successfully collected by a salt distillation operation. When the RE metals come into contact with a metallic structure, a galvanic interaction occurs dominantly, seemingly accelerating the U recovery reaction. These results elucidate the development of an effective and simple process that selectively removes actinides from electrorefining salt, thus contributing to the minimization of the influx of actinides into the nuclear fuel waste stream.

        The objective of the present study was to determine the best model to describe and quantify the changes in live body weight, height at withers, height at rump, body length and chest girth of Holstein cows raised under Korean feeding conditions for 50 months. The five standard growth models namely polynomial linear regression models, regression of growth variables on the first and second-order of ages in days (model 1) and regression of growth variables on age covariates from first to the third-order (model 2) as well as non-linear models were fitted and evaluated for representing growth pattern of Holstein cows raised in Korean feeding circumstances. Nonlinear models fitted were three exponential growth curve models; Brody, Gompertz, and von Bertalanffy functional models. For this purpose, a total of 22 Holstein cows raised in Korea used in the period from April 2016 to May 2020. Each model fitted to monthly growth curve records of dairy cows by using PROC NLIN procedure in SAS program. On the basis of the results, nonlinear models showed the lower root mean square of error (RMSE) for live body weight, height at withers, height at rump, body length and chest girth (12.22, 1.95, 1.55, 4.04, 2.06) with higher correlation coefficiency (R2) values for live body weight, height at withers, height at rump, body length and chest girth (0.99, 0.99, 0.99, 1.00, 1.00). Overall, the evaluation of the different growth models indicated that the Gompertz model used in the study seemed to be the most appropriate one for standard growth of Holstein cows raised under Korean feeding system.

        Intermedia refers to the convergence of media. The advance of intermedia has not only facilitated the delivery of brand messages in contemporary fashion shows but also facilitated interactive communication. This study investigated the mediating roles played by various media in fashion and fashion shows, focusing on the phenomenon of intermedia in contemporary fashion shows. To investigate the impact of intermedia on contemporary fashion shows, we conducted a social network analysis—a promising approach for research into fashion trends. Analyzing 159 fashion-related articles published in the 2000s, we extracted intermedia-related words (n=253). The relationships between keywords made an analysis of between centrality, and cluster variables applied Clauset-Newman-Moore by using KrKwic and NodeXL programs. The results of the between centrality analysis indicated that the most important factors in contemporary fashion shows are “models” and “stages.” We found that the impacts of intermedia on contemporary fashion shows can be divided into four categories: “model performance,” “symbolic stage management,” “new media utilization,” and “convergence in arts.” Our analysis thus identified considerable synergy between the characteristics of intermedia and contemporary fashion shows. These results have found intermediarelated commonalities in intermedia and fashion show, and this might increase customer interest in fashion, a positive outcome for the fashion industry.
