  • Currently, interest in the quality of concrete is increasing. Among the important factors for evaluating the quality of concrete, interest in unit-water content is also increasing. Currently, the air-meter method, the microwave oven drying method, the capacitance method, and the microwave penetration method are used to measure the unit-water content of concrete.. Among the above methods, except for the microwave method, the measurement method is complicated, portability is reduced, and economic efficiency is reduced. This research aims to measure a unit-water content by using a Frequency Domain Reflectometry(FDR) sensor that is economical, simple to measure, and portable among microwave methods. In addition, it is an experimental study to determine the accuracy of unit-water content using a single input residual model during deep learning to solve the limitations of the FDR sensor.

  • Purpose - Consumers have memories of their past time that they have not experienced. So consumers want to experience the past time and get pleasure through historical contents such as movies or dramas. This is because the re-created the past time sets the identity of the consumers who live today, and in the process, it give consumers emotional comfort. Consumers do not remember and sympathize with all of their historical time. In general, consumers remember the time that their communities are proud of. As s result, historical content is seen as a hero, and through that, consumers can check their identity. Also consumers experience positive emotions such as self-esteem, gratitude and pride through identification with heroes. That is, through historical contents, consumers can identify themselves and replace the current negative emotions with positive ones. Therefore, this study presents narrative identity and historical nostalgia that can affect positive evaluation of historical contents and suggest the factors the can induce such effects. This study was conducted to explain what the consumption effect of historical content is from a marketing perspective and what constitutes a component of historical content as a factor driving this effect. Research design, data, and methodology - This study has developed a questionnaire with 8 Hypotheses. The Films ('Masquerade(2012)', 'Roaring Current(2014)', 'Assassination(2015)', 'The Age of Shadow(2016)') and dramas('Six Flying Dragon(2015-2016)', 'Mr. Sunshine(2018-2019)') were used as experimental contents. 268 college students participated in this empirical study, and structural equation model was used to verify hypotheses. Results - Frist, narrative identity affects positive evaluation of historical contents. Nostalgia affect positive evaluation of historical contents. and narrative identity affects positive response of historical nostalgia. Second, character act relevance, circumstance similarity, and character attractiveness have positive influence upon response of narrative identity. Lastly, empathy for story and vividness of representation have also positive influence upon response of historical nostalgia. Conclusion - This study contributes to the theoretical and managemental development of historical contents. This study shows that narrative identity and historical nostalgia are important for success of historical contents. In order for historical content to be successful, it must manage elements of character act relevance, circumstance similarity, and character attractiveness, empathy for story and vividness of representation.

  • In this study, we developed a 15-week educational program for TPACK(Technological Pedagogical Content Knowledge) development of 40 pre-service teachers in a university for teacher training. We also developed a TPACK evaluation framework to evaluate the practical competency of TPACK of pre-service teachers. The developed evaluation framework consisted of 5 levels, from 0 to 4, TPK(Technological Pedagogical Knowledge), TCK(Technological Content Knowledge), and TPACK, respectively. As a result of the evlauation, the levels of TPK, TCK, and TPACK development stages of most pre-service teachers were consistent, but some pre-service teachers' TPK and TCK did not match. It was found that the TPACK stages follow the lower level between TPK and TCK. In addition, as a result of an investigation into the hindrance factors of the TPACK development of pre-service teachers with low TPACK stages in the use of technology, they have distrust of students' ability to learn with self-regulation, distrust of students' ability to interact, and recognition of practical limitations in the school field. Based on these findings, we argued that it was necessary to provide an educational program to help pre-service teachers develop balanced TPK and TCK and eliminate the hindrance factors of the TPACK development of pre-service teachers about technology-using classes.

  • The purpose of this study is to examine the effect of protein content on the physicochemical properties, gelatinized characteristics and textural properties of cowpea precipitate gels stored for 24 hrs and 48 hrs at room temperature. The contents of protein, total fat, and ash ranged from 0.35%∼1.38%, 0.54%∼0.64%, and 0.21%∼0.25%, respectively. The X-ray diffraction patterns were all Ca-type, showing no difference according to the protein content. Protein content did not make any difference in the blue values of cowpea precipitate. The blue value of cowpea precipitate powder as protein content was decreased. The water-binding capacity of cowpea precipitate powder increased as the protein content increased. Swelling power and solubility of cowpea precipitate powder increased as protein content decreased. The transmittance of cowpea precipitate powder was not different according to the protein content. The initial pasting temperature of cowpea precipitate powder by differential scanning calorimetry (DSC) and rapid visco analyser (RVA) showed no differences according to the protein content. In sensory evaluation, the color and clarity of cowpea precipitate gels stored for 24 hrs and 48 hrs at room temperature as the protein content increased, and the hardness, cohesiveness, springiness, acceptability were greater when the gels were stored for 48 hrs. Instrumental analyses using a rheometer showed that the hardness, gumminess, and chewiness of cowpea precipitate gels stored for 24 hrs, which was increased as the high protein content increased. For the gels stored for 48 hrs, all other factors are significantly different except cohesiveness as the protein content increased.
