In this paper, we propose an effective neural network model for image caption generation and model transfer. This model is a kind of multi-modal recurrent neural network models. It consists of five distinct layers: a convolution neural network layer for extracting visual information from images, an embedding layer for converting each word into a low dimensional feature, a recurrent neural network layer for learning caption sentence structure, and a multi-modal layer for combining visual and language information. In this model, the recurrent neural network layer is constructed by LSTM units, which are well known to be effective for learning and transferring sequence patterns. Moreover, this model has a unique structure in which the output of the convolution neural network layer is linked not only to the input of the initial state of the recurrent neural network layer but also to the input of the multimodal layer, in order to make use of visual information extracted from the image at each recurrent step for generating the corresponding textual caption. Through various comparative experiments using open data sets such as Flickr8k, Flickr30k, and MSCOCO, we demonstrated the proposed multimodal recurrent neural network model has high performance in terms of caption accuracy and model transfer effect.

General development basis of letter system is recognized by formative value in terms of its function and structure. principle of clustered writing is the most significant feature of Hangeul typography as considered that it is based on function and formativeness. Thus, not only by changes with its form but also by its characteristic syllable combination, space structure is made as consonants and vowels are combined in single letter, then the combination develop into word, sentence, paragraph to make second, third space structure character. This character has significant impact on readability that is core function of typography. With this property, space structure character is regarded as very important component of Hangeul typography. First, space structure character of Hangeul typography is reviewed by relating it to visual perception of gestalt psychology and compared square-framed letter and framed latter By applying square-framed letter and framed latter in same sentence, legibility and readability were studied. Researcher has found that space structure character of Hangeul typography has significant impact on its function, and in terms of future design, it is very critical not only for design but also for communication environment as space structure formativeness of Hangeul typography interact with communication that is basic concept.

This study aims at investigating and comparing the diphthongs, words, and sentences between two Korean highschool students groups using the Praat program. To do this English words and sentences were uttered and recorded by twenty Korean subjects; each group has ten subjects. All the subjects are female and their grades range from freshman to sophomore. Acoustic features were measured from a sound spectrogram with the help of the Praat software program and analyzed through statistical analysis. Results showed that the lengths of diphthongs and words were different between two groups, but the difference was not significant. However, in the lengths of sentence utterance, the group of 5 to 6 grade students in the current grading system pronounced longer than that of 1 to 2 grade students. Especially in the pronunciation of the first two sentences with more than five words, the difference was significant. From the data of the overall sum of words between the two subject groups, we were able to find out that the differences of the lengths of the words with the diphthongs were not significant, but those of the sentences with more than five words were significant. In the pronunciation of the words between coat and code, the length of the diphthong in coat was smaller than that of in code.

The purpose of this study was to qualitatively examine the meaning of students' drawings in outdoor classes and modeling-based learning cycles. Ten students were observed in a gifted education center in Seoul. Under the theme of the Hantan River, three outdoor classes and three modeling activities were conducted. Data were collected to document all student activities during field trips and classroom modeling activities using simultaneous video and audio recording and observation notes made by the researcher and students. Please note it is unclear what this citation refers to. If it is the previous sentence it should be placed within that sentence's punctuation. Hatisaru (2020) Ddrawing typess were classified by modifying the representations in a learning context in geological field trips. We used deductive content analysis to describe the drawing characteristics, including students writing. The results suggest that students have symbolic images that consist of geologic concepts, visual images that describe topographical features, and affective images that express students' emotion domains. The characteristics were classified into explanation, generality, elaboration, evidence, coherence, and state-of-mind. The characteristics and drawing types are consecutive in the modeling-based learning cycle and reflect the students' positive attitude and cognitive scientific domain. Drawing is a useful tool for reflecting students' thoughts and opinions in both outdoor class and classroom modeling activities. This study provides implications for emphasizing the importance of drawing activities.

There were several methods of conception in seeking a visul idea of the advertising design. However, such conventional methods had a tendency that the degrees of utilization and satisfation are lacking. Also, in a thumbnail sketch phase, there was a great tendency to seek an idea based on pictorial elements only and thus depended chiefly on the existing references. Accordingly, originality was not high. Further, under the background which any common methods of a designer and a copywriter, if they have effective. I would like to propose a visul idea conception method, a condensing & amplification method for maintaining a logical system of advertising intelligence and for facilitating creative visualization through a language-oriented approach. The condensing & amplification method is the method of conception, in which after an appeal point as per advertising intelligence is passed through sentence and phrase and then condensed with word, various variation for the word develop, and by selecting the most creative word of the results, the thumbnail sketch commences based on the results amplified with the phrases and sentences.

Numerous methods can be employed to teach students and farmers on soil science and fertilizer. The cartoon is one of the most effective teaching aids both for instructors and students. Instructor becomes a director of the cartoon to organize the framework of story based on the chapter of lecture. Director should adapt the regular sentence on soil science into the short and concise scenario suitable for the visual expression of the cartoon, followed by the selection of the scene for drawing. Next is to cast the instructor for the role of actor or sometimes supporter. After casting, the director starts to draw each cut of the cartoon in sequence. I published the cartoons in weekly serials in the farmer's newspaper for three years. Each cartoon was composed of eighteen cuts and formatted with the introductory, main and conclusive issues. Cartoon started with dialogues between the cast on subject to stimulate the interest by farmers, inserted the tables and graphs for the scientific knowledge and summarized the chapter. Major contents covered in the cartoons were glossary, nutrient uptake, pH, salt accumulation, moisture, pollution, chemical fertilizer, compost and other general aspects of soils. Cartoons had been very popular serial of the newspaper and are archived in the web for reviewing.

As the main mathematical concepts are presented and expressed in various ways through textbooks during the teaching and learning process, it is necessary to look at the representations used in elementary math textbooks to find effective guidance. This study analyzed sentences used in the definition of mathematical terms and unit assessments of current elementary mathematics textbooks according to word depth (Yngve, 1960) from a syntactic perspective. As a result of the analysis, it could be seen that the sentences in textbook were generally concise, the word depth was lower, and the sentence structure and form were different depending on the individual characteristics of each term. Also, the sentences in the lower grade textbooks were more easily constructed, and the sentences of the term definition were more complex than the sentences of the unit assessments. Efforts should be made to help learners learn mathematical concepts, such as clarifying sentences in textbooks, presenting visual materials together, and providing additional explanations to suit the level of individual learners.

This study aimed to examine whether there are differences in reading performance between digital and print media by measuring reading speed of paragraphs on print materials and tablet PC. To investigate whether the physical characteristics of the media influence reading performance, the format of text was kept as similar as possible between print and digital media. We also compared conditions in which paragraphs consisted of either long or short sentences to explore if there were differential effects on reading performance based on sentence length across different media. Additionally, reading speed was analyzed based on reading span to investigate whether there were differences in reading performance according to participants' working memory capacity. As a result, reading speed was faster when reading print media compared to digital media. However, there was no difference in reading speed based on the length of sentences composing the paragraphs. Participants with a higher reading span exhibited faster reading speed compared to participants with a lower reading span. Moreover, participants with a higher reading span read paragraphs composed of long sentences faster on print media than on digital media. The findings of this study suggest that visual fatigue induced by tablet PCs and participants' working memory capacity may impact reading speed.

Unlike a study related in language alone, rhetorical study of current time, composed with multi-culture, medias, communication, presents its own field that covers from the form of discourse(persuasive) to another form of discourse(not persuasive). If there was a study of making beautiful sentences for story and finding simple method of speech in Greek and roman period of an ancient time, it now a study in which one finds the essence of literary style or terminology in the expression of sentence. The taller case is especially important, given that the importance of what to express visually is on-going active procedure of this stuffy as itself an activity of communication. When a visual object persuades viewers, the activity of communication derives them to react and to understand the intention of an artist. The matter of how to speak is the matter of how to shape message persuasively. This persuasive method or technique is study of rhetoric. The three aspects (figurative, accentuating, mutating) of rhetorical expression of an illustration, the visual image can give fresh feelings to be in intimate relations with public. These rhetorical expressions also vitalize the story that is expressed on illustration with crisp image. It helps to attain expected effects while discovering essential meaning through the corresponding linguistic interpretation of an image. The study aims at the most effective way to communicate by figuring the most strong and direct illustrative message out. One of the method is to patternize illustrative expressions that are established from all kinds of shapes of Rhetoric. Therefore ,an operation of significance and an implication can shape an ultimate goal of this study from acknowledging the mechanism that modern illustration embraces.

The purpose of this study is to obtain implications for mathematical education by analyzing how the multiplication and division of decimal numbers are presented in the elementary mathematics textbooks in Korea, Japan, Singapore, and Finland. Compared to the fact that students often have misconceptions about multiplication and division of decimal numbers, there have been not many comparative studies in recent elementary mathematics textbooks. For this study, we selected elementary mathematics textbooks those are widely used in Japan, Singapore, and Finland along with Korean elementary mathematics textbooks. We chose the textbooks because the students in the selected countries have scored high in international achievement studies such as TIMSS and PISA. The analysis was examined in terms of elementary mathematics curriculum related to multiplication and division of decimal numbers, introduction and content, real-life situations, use of visual models, and formalization methods of algorithms. As a result of the study, the mathematics curricula related to multiplication and division of decimal numbers includes estimation in Korea and Finland, while Japan and Singapore emphasize real-life connections more, and Finland completes the operations in secondary schools. The introduction and content are intensively provided in a short period of time or distributed in various grades and semesters. The real-life situations are presented in a simple sentence format in all countries, and the use of visual models or formalization of algorithms is linked to the operations of natural numbers in unit conversions. Suggestions were made for textbook development and teacher training programs.
