  • This study was performed to find out the quality characteristics of rice noodles by addition of red ginseng(0, 2, 6, 10%). The quality characteristics of the sample were estimated in terms of general composition, growth of microorganism and sensory evaluation. The results from this study were as follows. The protein, lipid and ash contents did not show significant difference in any of the groups. In dry rice noodles, moisture content significantly decreased in red ginseng groups but, in half-cooked rice noodles, moisture content significantly increased in 6 % and 10% red ginseng added groups(p<0.05). The microbial count showed less growth in red ginseng added groups after 3 months(p<0.05). According to sensory evaluation, surface color proved very good in the 10% red ginseng added group among the training panel while very good in the 2% red ginseng added group among consumers. Flavor was good in red ginseng added groups(p<0.05). Taste was very good in the 3% red ginseng added group. Appearance and overall quality were highest in the 2% and 6% red ginseng added groups(p<0.05). Therefore, rice noodles containing 2% or 6% red ginseng were most preferable and safe during 5 months and 6 days in dry and half-cooked noodles respectively.

  • In the evaluation method of KS on the activity factor of fly ash, same amount of cement should be replaced with fly ash. Therefore, contradictory effects on concrete strength exist, i. e. strength decease due to low content of cement and strength increase of strength due to filling-pore-function of fly ash. European Committee for Standardization (CEN) specifies the method 1 to 4. adding fly ash without reducing the content of cement, for the evaluation method on activity factor of fly ash. This study investigates the applicability of the method 2 of CEN to mix design of concrete. The followings are derived ; There is a key ratio of f)y ash mixing which enhances the incremental ratio of mixing water to improve fluidity of mortar. The incremental ratio of mixing water is maximized about 11% ratio of fly ash mixing. Compressive strength most slightly increases at that ratio of fly ash mixing. Activity factor of fly ash increases as water-cement ratio becomes low and contents of fly ash becomes high. Moreover, quality of fly ash and condition of mix design affect the applicable amount of fly ash and available range of water-cement ratio. However, this method has some problems for practical purpose because activity factors of fly ash for some cases are over 1.0. Further research should be conducted to develop more useful method of evaluating activity factor of fly ash.

  • This study was performed to the investigate the Yackwa quality according to the addition level of cellulose(0, 1, 3, 5 and 7% w/w flour). The color(L, a and b value), hardness, crude lipid content and sensory evaluation of Yackwa were measured. The values for color(L, a and b value) were not shown any significant difference among the all of Yackwa groups, but L(lightness) tended to be increased in 5 and 7% cellulose Yackwa groups than cellulose free Yackwa(control). The 7% cellulose Yackwa was harder than control, but the hardness of Yackwa didn't show difference in groups added below 5% cellulose compare to control. Crude fat contents showed no significant difference in the all Yackwa groups but tended to decrease in Yackwa groups added above 1% cellulose than control. It could be thought that fat absorption of Yackwa was affected due to adding a cellulose. There were not found any significant differences in the taste values for sensory evaluation according to cellulose level, and overall acceptability in below 5% cellulose Yackwa groups didn't differ from control. On the other hand the higher level of cellulose, the more crispness which was positively associated with overall acceptability. These findings could be thought that the addition of 3% cellulose(w/w) in preparing Yackwa were needed to reduce the fat absorption and to increase the crispness without changing the tastes and overall acceptability of Yackwa.

  • The KJC and KCI services operated by the National Research Foundation of Korea (NRF) need to refer to the global citation index database to set the service direction that researchers want and develop new functions. Therefore, in this study, the usability of Korea's KJC and KCI web databases was evaluated. In addition, FGI verification was performed for a group of experts on KJC and KCI improvement measures derived by academic information experts. The evaluation committee consisted of the researcher group, the society related group, the publisher (academic information distribution organization) group, and the policy-making organization group. A total of 16 experts performed usability evaluation and service improvement proposals for KJC and KCI services. As a result of usability evaluation of KJC and KCI web database using SUS measurement tool, KJC service was evaluated as 73.44, and KCI service was evaluated as good as 64.38. KJC improvement proposals were evaluated positively with 4 points or more for all improvement items, and KCI improvement proposals were positively evaluated with 3.5 points or more for all improvement items. Overall, KJC and KCI error improvements were evaluated with a score of 4 or more, showing strong affirmations. In the future, it is hoped that the improvement proposals and improvements proposed in this study will be applied to the development of KJC and KCI services, so that more quality services will be used by domestic researchers.

  • In this study, safety education contents for medical radiation workers were produced based on Mixed Reality(MR). Currently, safety training for radiation workers is based on theory. This is insufficient in terms of worker satisfaction and efficiency. To address this, we created ICT(Information and Communication Technologies)-based MR radiation worker safety education content. The expected effect of Mixed Reality worker safety education content is that education is possible without space and time constraints, realistic education is possible without on-site training, and interaction between images is possible through reality-based 3D images, enabling self-directed learning Is that. In addition, learning in a virtual space expressed through HMD(Head Mounted Display) is expected to make education more enjoyable and increase concentration, thereby increasing the efficiency of education. A quantitative evaluation was conducted by an accredited institution and a qualitative evaluation was performed on users, which received excellent evaluation. The MR safety education conducted in this study is expected to be of great help to the education of medical radiation workers, and is expected to develop into a new educational paradigm as online education in accordance with Corona 19 progresses.

  • The present paper focuses on the interaction between lexical-semantic information and affective prosody. The previous studies showed that the influence of lexical-semantic information on the affective evaluation of the prosody was relatively clear, but the influence of emotional prosody on the word evaluation remains still ambiguous. In the present, we explore whether affective prosody influence on the evaluation of affective meaning of a word and vice versa, using more ecological stimulus (sentences) than simple words. We asked participants to evaluate the emotional valence of the sentences which were recorded with affective prosody (negative, neutral, and positive) in Experiment 1 and the emotional valence of their prosodies in Experiment 2. The results showed that the emotional valence of prosody can influence on the emotional evaluation of sentences and vice versa. Interestingly, the positive prosody is likely to be more responsible to this interaction.

  • Properties of concrete using low heat portland cement is different from using ordinary portland cement and temperature of aggregate can be expected to have an important influence on its properties. In this study, experiment by setting up 5 levels (40, 30, 20, 4, $-2^{\circ}C$) by temperature of aggregate for evaluation properties of concrete using low heat portland cement was conducted. The experiments include slump test, air content test, change of slump, change of air content and compressive strength of concrete test. As the result of experiments, slump and air content was decreased by increasing temperature of aggregate. But it was not exceeding it's limit. Change of slump and air content was rapidly decrease by decreasing temperature of aggregate. At early age, compressive strength was influenced by the temperature of aggregate.
