A robot's recognition and diagnosis of pronunciation and its speech are the most important interactions in RALL(Robot Assisted Language Learning). This study is to verify the effectiveness of robot TTS(Text to Sound) technology in assisting Korean English language learners to acquire a native-like accent by correcting the prosodic errors they commonly make. The child English language learners' F0 range and speaking rate in the 4th grade, a prosodic variable, will be measured and analyzed for any changes in accent. We compare whether robot with the currently available TTS technology appeared to be effective for the 4th graders and 1st graders who were not under the formal English learning with native speaker from the acoustic phonetic viewpoint. Two groups by repeating TTS of RALL responded to the speaking rate rather than F0 range.

Over the last few years, the major airports in Asia have been operating at or close to their capacity. As a result, Korea, Japan, China, Hong Kong, Thailand, Malaysia, and Indonesia decided to expedite the development of new airports. Accordingly, some of the existing airports have been completely used as other functions or purposes and the others operated as a domestic airport. In the latter case, re-development plans are needed for idle facilities. This paper evaluates the alternative options for re-development of idle airport facilities of Seoul Gimpo International Airport. The proposed methodology makes it possible to provide a practical and applicable evaluation of airport re-development plan. In particular, it can take into account the qualitative aspects of different interesting groups such as airport experts. passengers and airport peripheral community. The interview was conducted in order to obtain the different groups' view. To evaluate and select the best option of the airport re-development, this study adopted a fuzzy linguistic approach.

The domestic content market has grown continuously. Furthermore, content consumption has rapidly increased in the COVID-19 era. For these reasons, it is necessary to investigate consumer behavior related to content business. This study focuses on content names as a key factor that induces consumers' interest in the content. In particular, this research examines if the conceptual fluency of the content name affects consumers' liking for the content. In addition, it explores the moderating effect of style of information processing (verbalizer vs. visualizer). The results of an experiment shows that the conceptual fluency on the content name is positively influential for liking content. Also, there was a significant interaction effect between verbalizers and conceptual fluency on content name. This study has important findings in terms of content marketing strategies. Above all, it has strong points because this research examines the style of information processing as an important consumer characteristic variable.

Recently, lots of research on automated test data generation has been actively done. However, techniques for automated test data generation presented so far have been proved ineffective for programs with flag variables. It can present problems when considering embedded systems such as engine controllers that make extensive use of flag variables to record state information concerning devices. This paper introduces a technique for generating test data effectively for programs with flag variables. The presented technique transforms the test data generation problem into a SAT(SATisfiability) problem and makes advantage of SAT solvers for automated test data generation(ATDG). For the ends, we transform a program under test into Alloy which is the first-order relational logic and then produce test data via Alloy analyzer.

We have proposed BIST method and circuit for embedded 16M SDRAM with logic. It can test the AC parameter of embedded 16M SDRAM using the BIST circuit capable of detecting the address of a fail cell of a 16M SDRAM installed in an Merged Memory with Logic(MML) generating the information of repair for redundancy circuit. The function and AC parameter of the embedded memory can also be tested using the proposed BIST method. The total gate of the BIST circuit is approximately 4,500 in the case of synthesizing by $0.25\mu\textrm{m}$ cell library. and verify the result of Verilog simulation. The test time of each one AC parameter is about 200ms using 2Y-March 14N algorithm.

A recognizable form having meaning is called a sign in semiotics. The sign is transformed into a physical counter form in this work. Its internal structure is restricted on the linguistic concept structure. We borrow the concept of a mathematical function from the utility function of a rational personal in the economy. Universalizing the utility function by introducing the consistency of independency on the manner of construction, we construct the probability. We introduce a random variable for the probability and join it to a position variable. Thus, we propose a physical sign and its serial changes in the forms of stochastic equations. The equations estimate three patterns (jumping, drifting, diffusing) of possible solutions, and we find them in the one-day stock-price flow. The periods of jumping, drifting and diffusing were about 2, 3.5, and 6 minutes for the Kia stock on 11/05/2014. Also, the semiotic sign (icon, index, symbol) can be expected from the equations.

This study is a descriptive survey using a self-reported survey method to understand the effect of language and non-verbal communication of medical service providers on customer satisfaction through Lapport and to determine the degree of impact on Lapport by adjusting perceived service authenticity. The data collection period was from April 5 to April 30, 2021. Using the convenience sampling method, data were collected from users of medical institutions located in Busan and Gyeongsangnam-do, and a total of 306 valid questionnaires were used as statistical analysis data. The collected data were analyzed using the IBM SPSS statistics version 25.0 and AMOS 20.0 programs through a coding process. In the results of this study, it was found that the language and non-verbal communication of medical service providers influenced customer satisfaction through Lapport, and the perceived service authenticity in the relationship between each variable acts as a moderating effect. Considering that the language and non-verbal factors of the medical service provider are important in the interaction between the medical service provider and the hospital user, the medical service provider should take full account of the language and non-verbal factors and help the medical institution communicate with the hospital user.

This paper proposed new approach for the information gifted discrimination test usign EPL. We tried to distinguish high level thinking in the information gifted through test of this study. We designed discrimination test by the features of EPL and developed testing item tool like single-sprit and multi-sprite. These items are divided into adding block, changing the block order, modifying value io block, and changing a block. We designed this testing tool that the elementary students can solve items without an experience on learning programming language. We expect the testing tool io proposed this study will help to discriminate the information gifted effectively.

The loop is a fundamental for the parallelism exploiting as it has a large portion of execution time for sequential Java program on the parallel machine. This paper proposes the method of exploiting the implicit parallelism through the analysis of data dependence in the existing Java programming language having a single loop structure. The parallel code generation method through the restructuring compiler and the translation method of Java source program into multithread statement, which is supported in the level of the Java programming language, are also proposed here. The performance test of the program translated into the thread statement is conducted using the trip count of loop and the thread count as parameters. The restructuring compiler makes it possible for users to reduce overhead and exploit parallelism efficiently in the Java programming.
