There are highly toxic radio-isotopes and high heat emitting isotopes in spent nuclear fuels which could be a burden in a deep geological repository. Some preliminary study in order to see if there are some advantages in terms of waste burden, in case that the spent fuel is appropriately processed and then disposed of in a final repository, has been carried out at KAERI. This study is focused on the proliferation resistance for various processing alternatives for them. The evaluation criteria and their indicators for proliferation resistance analysis are selected and then evaluated quantitatively or quantitatively for the alternatives. The processing alternatives are grouped into three categories according to the level of decrease of burden for final disposal and named them as Level I, Level II and Level III technolgy alternatives. Level I alternative is to maximize the long-term safety in the final repository from the removal of I- 129, semi-volatile radioisotope, which is the greatest impact on the long-term safety of the repository. Level II alternative is to remove the strontium-90, high heat emitter, in addition to the removal in Level I. The Level III is to additionally remove uranium from main stream of the level II to reduce the volume of the high level wastes to be disposed. The intrinsic radiation and chemical barriers against the nuclear proliferation are selected and analyised for the alternatives. It is resulted from the proliferation resistance analysis that all three options showed excellent resistance to nuclear proliferation for the two barriers. However, Level III technology including electrochemical refining process is relatively a little weaker than others. Overall, it could be an effective means to reduce the burden of disposal if the spent fuels are appropriately conditioned for final disposal. Further detailed studies are, however, needed to finalize its feasibility.

생체용 마그네슘 합금은 전연성 부족과 열에 의한 팽창률 변화가 심하여 2mm 이하의 판재를 만드는 것이 매우 어려움 문제이다. 이를 해결하기 위해 압연 방식, 세이퍼 방식, 밀링 방식 등의 다양한 방법이 존재할 수 있다. 압연 방식을 적용하여 실험을 진행하였으나 Mg 합금은 전연성, 취성의 문제로 인해 파괴되는 현상이 발생하였다. 그리고 세이퍼 방식은 가공시 충격이 발생하는 단속절삭이기 때문에 표면에 자국이 남게 되고 시험편이 휘어지는 현상이 발생하는 문제가 발생하였다. 최종적으로 밀링 방식으로 전환하여 가공실험을 수행해 본 결과 매우 만족할 만한 결과값을 얻게 되었고, 이 결과는 절삭조건을 절삭회전수 1000rpm, 이송속도 127mm/rev, 절삭깊이 0.5mm로 엔드밀 사용하여 가공하였을 때 Ra = 0.44㎛의 표면거칠기값을 얻게 되었다. 본 논문에서는 생체 마그네슘 합금재료로 미소판재를 가공하였을 때 매우 좋은 표면을 유지하며 2mm 이하의 미소 두께를 지속적으로 가공이 가능하도록 하였으며, 다양한 절삭조건, 2날과 4날 엔드밀 날수 변화 등을 통해 최적의 가공조건을 알아보는 실험을 진행하였다.

Heavy bitumen scattered in the underground sedimentary layer is a kind of unconventional energy source, and by extracting it, a production well is excavated in the sedimentary layer and high-temperature and high-pressure steam is injected to reduce the viscosity of bitumen and recover it to the ground steam assisted method is applied. As a recovery method that uses the steam effect of the dilution effect of solvent injection, it is a recovery method that can increase thermal efficiency. In this study, the process system of the central processing facility(CPF) of the hybrid steam-solvent recovery method that injects solvent into the existing steam assisted method was analyzed, and the core facilities for each process were identified, and hybrid steam-solvent recovery compared to the existing steam assisted method. In the case of the method, it was evaluated that the amount of steam supply and all utility costs decreased according to the solvent injection.

The purpose of this study is to analyze the structure, status and economic ripple effects of the fisheries processing industry in Korea using interindustry analysis. Five input-output tables published over the past twenty years have been reclassified with a focus on the fisheries processing sector. Through these multi-period tables, we analyzed changes in the inducing effects in production, value added and employment as well as the backward-forward linkage effects. As a result of the analysis, it was found that the industrial scale of the fisheries processing industry is very small compared to other food manufacturing industries. The backward linkage effect of the fisheries processing industry was greater than that of other industries, but the forward linkage effect was rather low. This means that the fisheries processing industry can be greatly affected by industrial depression of the downstream industries such as fishery and aquaculture. Production and employment-inducing effects of the fisheries processing industry have shown a decreasing trend in recent years. This reflects the reality that intermediate inputs are gradually being replaced by imports from domestic production due to the expansion of market opening and the depletion of fishery resource. In the future, it is necessary to prepare a strategy to increase the value-added productivity of the fisheries processing sector and foster it as an export industry.

This study was developed to recognize the occurrence of 250[m] of experimental distance, rain and nighttime as an educational and training device without any safety accidents by applying algorithms to optical filters and noise filters to be used in all weather environments and closest to actual shooting training using IR Laser. There are live-fire shooting using live ammunition, screen shooting using beam project and screen, MILES using IR Laser and sensor, BB shooting using compressed gas and BB bullet, and painting shooting using CO2 gas and paint bullet. Among them, the actual shooting training is not efficient in terms of management and operation because it requires considerable risk factors and large costs in preparation for the highest efficiency. Therefore, training that replaces these problems is needed, and various alternative shooting training is being implemented. Therefore, research and development was conducted to solve these problems by using it as one of efficient shooting training and education systems. This study was conducted to develop high-performance and low-cost precision shooting training equipment to contribute to strengthening the defense of the Republic of Korea.

INTRODUCTION Online marketing has grown rapidly over the past years and has become a key component when making marketing mix decisions. Over 2014, internet advertising revenues in the U.S. increased 16% from the previous year to a total of $49.5 billion (IAB 2015). In addition, according to Online Publisher Association, video advertisements have reached the majority of the Internet users (66%), and have resulted in an action from almost half of the users. The significant business opportunities provided by the online environment are reflected as the increasing amount of attention for online advertising in academic research (Mei et al. 2008). It is yet to be researched how online videos and the accompanied online video advertisements interact and how advertisement customization can play a role to possibly optimize user experience and therefore the effectiveness of online video advertisements. Particularly, congruity forms a key opportunity for customization in embedded online video advertising. Congruity is defined as consistency between the ad and video or the advertised product and video (Moore et al. 2005). Evidences in extent literature have shown the positive effects of congruity on, for example, the processing fluency of the ad, the consumer attitudes towards the ad and the persuasiveness of the ad (Moore et al. 2005). However, in the context of online video advertising, limited research has been conducted on this topic. The main goal of this research is to explore the effect of online video advertising congruity on consumer attitudes towards the online video, advertisement and advertised product. Therefore, this research attempts to examine the information processing of a consumer and how congruity acts in this process to affect consumer's preferences. Due to the nature of this research question, an online experiment is used to test the hypothesized relationships of the conceptual model. The collected data in this study were examined using partial least squares (PLS). CONGRUITY AND PROCESSING FLUENCY Congruity can be defined in terms of similarity. The perceived similarity between two given stimuli of equal importance, determines their congruity (Rokeach & Rothman, 1965). Extensive research has been conducted on the effects of congruity in advertising. For example, studies have focused on congruity between involvement types of ads and TV programs (Sharma, 2000), viewer's mood-ad content congruity (Kamins, Marks, & Skinner, 1991), and program context- advertised product congruity (De Pelsmacker, Geuens, & Anckaert, 2002). Previous research from (Moore, Stammerjohan, & Coulter, 2005) has shown that congruity has a positive effect on consumer attitudes. Research on online banner advertisements on websites has indicated that advertisements should be consistent with the website brand (Newman, Stem Jr, & Sprott, 2004). Appeal congruity can then be achieved when the appeal of the online video and the appeal of the embedded ad are similar: an emotional (affective) video paired with an emotional ad can be deemed congruent. Similarly, an informational ad will be more effective when embedded in an informational video. In this study, Ad-and-Video congruity represents such type of congruity. Based on extent research on processing fluency, it can be assumed that online video advertising congruity, either in terms of appeal or content, will result in more processing ease of the ad as the information provided by the video and ad is similar. The following hypotheses are formulated: Hypothesis 1: Congruity between the appeal of the online video and the appeal of the advertisement has a positive effect on processing fluency. Hypothesis 2: Congruity between content of the online video and the advertised product has a positive effect on processing fluency. We further propose that the above process is influenced by ad/video appeal or execution format (emotional vs. informational). An informational ad format is defined as an ad execution designed to appeal to the rationality of the receiver by using objective information describing a brand’s attributes or benefits, while an emotional ad format as an ad execution designed to appeal to the receiver’s emotions by using drama, mood, music and other emotion-eliciting strategies (Yoo & MacInnis, 2005). When an individual is watching an emotional ad or video, the possible effect of Ad-video or Product-video congruity on a consumer's processing fluency will be attenuated. The following hypotheses are formulated: Hypothesis 3a: Congruity between the appeal of online video and the appeal of embedded advertisement has a stronger effect on processing fluency for informational appeals than for emotional appeals. Hypothesis 3b: Congruity between content of the online video and the advertised product has a stronger effect on processing fluency for informational contents than for emotional contents. Involvement and processing fluency With regards to online advertising, research has shown that the degree to which a consumer is involved with the topic of a website also affects the processing of online advertising. It can be argued that when an individual is not involved in watching an online video, its effect on a consumer's processing fluency will be absent. On the other hand, when a consumer is highly involved in watching an online video, it is more likely that the viewer experiences processing fluency. As a result, in this situation, involvement may actually affect processing fluency of the viewer. Based on these findings, the following hypothesis is formulated: Hypothesis 4: Involvement has a positive effect on the processing fluency of consumers. Post-viewing attitudes Research has also indicated the mediating role of an individual’s affective response from processing fluency to its evaluation (Winkielman & Cacioppo, 2001). A viewer of an online video is shown an ad that has the same appeal as the video, making it rather easy to process. The viewer appreciates this as it takes less effort to view the ad and to relate to advertised product to the content of the video and the viewer's interests. As a result the viewer is more likely to generate a positive attitude towards the ad, the advertised product and the video. The insights lead to the formulation of the following three hypotheses: Hypothesis 5: Processing fluency has a positive effect on the attitude towards the online video. Hypothesis 6: Processing fluency has a positive effect on the attitude towards the advertisement. Hypothesis 7: Processing fluency has a positive effect on the attitude towards the advertised product. Figure 1 shows the conceptual model, which summarises the hypothesized relationships. <Insert Figure 1 about here> METHODOLOGY We conducted an experiment in the form of a 2 (type of appeal: informational vs. emotional) × 2 (Ad-Video congruity: congruent vs. incongruent) × 2 (Product-Video congruity: congruent vs. incongruent) full-factorial between-subject design. Video and advertisement appeal are each measured by the three items derived from the study by Moore et al. (1995) on the individual difference in response to advertising appeal. Processing fluency is measured by two items of the study by Lee and Aker (2004). Three items of the study from Zaichowsky (1985) are used to measure the involvement of the participants. The three items related to the attitude towards the video, advertisement and product are derived from the respective studies from Russell et al. (2004) and Kozup, Creyer and Burton (2003). Returned questionnaires numbered 276 responses with 24 incomplete data, resulting in 252 valid responses for data analysis. The collected data in this study were analyzed using partial least squares (PLS). Measurement model A measurement model was used to evaluate reliability, convergent validity, and discriminate validity. A structural model was used to determine the significance and association of each hypothesized path, and the explained variance. Reliability was examined by composite reliability values above the 0.70 benchmark (Fornell and Larcker 1981). Results show all values above 0.70, indicating satisfactory reliability. Convergent validity was examined by all indicator loadings that were significant and exceeding 0.7 and average variance extracted (AVE) by each construct exceeding 0.50 (Fornell and Larcker 1981). Results shows all indicator loadings above 0.70 and all AVEs exceeding 0.50, indicating satisfactory convergent validity. Discriminant validity is demonstrated by the square root of the AVE for each construct exceeding the correlations between the constructs (Chin 1998). These results indicate that the proposed models have good reliability and validity. Structure model Figure 2 shows the standardized path coefficient, the significance of each hypothesized path and the variance explained (R²). H1 and H2 investigate the effect of Ad-Video congruity and Product-Video congruity on processing fluency. Results show that Product-Video congruity is positively related to processing fluency (β=0.115, t-value=2.131, p<0.05), supporting H2. However, the effect of Ad-Video congruity on processing fluency is not significant ((β=0.022, t-value=0.377, p>0.05). Thus, H1 is not supported. H3a and H3b examine the moderating effect of the type of appeal. The hypothesis testing of H3a and H3b is discussed under the multi-group analysis (PLS-MGA). H4 proposes that involvement has a positive effect on the processing fluency of consumers, which is supported by the results (β=0.399, tvalue= 6.778, p<0.05). H5, H6, and H7 investigate the effects of processing fluency on post-viewing attitudes. Processing fluency is positively related to attitude towards the video (β=0.192, t-value=2.838, p<0.05), advertisement (β=0.426, t-value=7.607, p<0.05) and the focal product (β=0.422, t-value=7.171, p<0.05). These results support H5, H6 and H7. <Insert Figure 2 about here> We hypothesize that the type of appeal (informational or emotional) moderates the effects of Ad-Video congruity and Product-Video congruity on processing fluency in H3a and H3b. Specifically, the effects on under informational appeal condition are stronger. To test for group differences, we applied a multi-group analysis (PLS-MGA) approach. The PLS-MGA results for both informational and emotional groups, show that that the positive effect of Ad-Video congruity on processing fluency is only significant for informational appeals (β=.150, t-value=1.99, p<.05) but not emotional appeal (β=-.010, t-value=.15, p>.05), supporting H3a. Similarly, results show that that the positive effects of Product-Video congruity on processing fluency is only significant for informational appeals (β=.170, t-value=2.27, p<.05) but not emotional appeal (β=.050, t-value=.57, p>.05), supporting H3b. CONCLUSION Results show that congruity is related to the improvement of processing fluency only for informational ads/videos. This finding provides some support to the processing fluency theory which holds that less discrepant information should result in a higher processing fluency and extends the existing literature by investigating the appeal/execution format as a boundary condition. Involvement itself has been found to be positively related to processing fluency. Thus, when a consumer is initially more involved in watching a video, the processing fluency increases. This is in line with previous research that proved that involvement positively affects the attention that is given to advertisements and ultimately also the attitude of consumers.

Even though the red pepper is one of the most important seasoning vegetables in Korea, the volume of usage of domestic red pepper has shrunk due to decrease in consumption. Thus, researchers and government officers need to seek for solutions to extend usage of domestic red pepper of food processing industry which consumes considerable amount of it. The purpose of this paper is to analyze the factors of the usage of domestic red pepper in food processing companies using cross-tabulation analysis and multiple regression model and to find the implications for promoting the usage of domestic red pepper. The results of studies present that specific characteristics of food processing companies affect the usage of domestic red pepper, including size of sales, shape of company, food product processed by company, human organization for purchase of food material, registered trademark, and support of government. This study also suggests that government needs to offer more supporting programs to sauce industry and improve the system of program to promote the usage of domestic red pepper.

In this article, to predict the wear amount of nano particles in a worn nano composite, computational analysis pre/post-processor were developed using ABAQUS and visual basic programs. The abrasion, which is one of nano particles release scenarios, was applied in the computational analysis. Moreover, reciprocation, which is the abrasion type, was selected and incarnated in abrasion computational analysis. Also, to predict wear amount of nano composite in computational analysis, archard equation was applied and the predicted wear amount was evaluated compare with experimental value. The predicted wear amount of nano composite was increased in accordance with increasing force and was similar to result of experimental value.

In this study, the transfer rate of wild type Listeria monocytogenes (LM) was investigated to establish the standard of safety management during pork meat processing for meat to meat and meat to food contact surfaces contamination at 5 and 10oC. The transfer rate of LM from meat to meat during the processing increased from 0.02% after 30 min to 0.42% after 120 min at 5oC, while for conveyor belt and stainless steel, it decreased from 0.015% and 0.013% after 30 min to 0.002% and 0.0003% after 120 min at 5oC, respectively (p < 0.05). When temperature increased to 10oC, the transfer rates of LM from meat to meat, conveyor belt and stainless steel were the highest at 60 min exposure, and all decreased after 120 min. In reverse, the transfer rate from food contact surface to pork meat was significantly higher than that from pork meat to food contact surface (p < 0.01). Also, the transfer rate to conveyor belt was significantly higher than stainless steel (p < 0.05) and it was highest at 30 min exposure time in both 5 and 10oC. This study indicates that the transfer and adherence rates of LM are influenced by the contact time and temperature. Consequently, these results were utilized to develop a predictive model with a high level of confidence which can lead to prevent cross-contamination during pork meat processing.

This study was conducted to assess the levels of microbiological hazards of preprocessed Namuls, which were served at the school foodservice. 19 preprocessed ground or root vegetables were collected from 21 schools in May to June of 2011. Heavy contamination of aerobic plate counts (from 3.39 to 8.42 logCFU/g) and total coliform groups (from 3.16 to 7.84 logCFU/g), enterobacteriaceaes (from 2.53 to 7.55 logCFU/g) were detected in preprocessed Namuls. In addition, the detection rates of Escherichia coli, Staphylococcus aureus and Bacillus cereus (emetic form) were 4.3%, 11.7% and 2.1%, respectively. In addition, sanitary indicative bacterium at preprocessing steps of root vegetables (lotus root, burdock root, bellflower root) and blanched Namuls (bracken, sweet potato vine, chinamul) were analyzed. Aerobic plate counts, coliform groups, and enterobacteriaceaes were not effectively removed during preprocessing including washing and soaking steps. In the case of blanched Namuls (bracken, sweet potato vine, chinamul), contamination levels increased more after drying process and no significant reduction effect on the levels of microbial contamination was observed during preprocessing steps. Thus, effect of preprocessing steps on the microbiological hazards in Namuls must be reevaluated to improve the microbiological quality of preprocessed Namuls at the school foodservice and retail markets.
