In this study, we analyzed the written and drawn explanations of thirty elementary school pre-service teachers in order to examine their perception on the seasonal length of day and night. The main findings are as follows: First, pre-service teachers used the most common term in the description of the texts, such as meridian altitude, axis of rotation, and revolution, and there were more misconceptions in the drawn explanation than in the written explanation. Second, by analyzing the pre-service teachers' perceptions by combining written and drawn explanations, it is possible to detect scientific errors that the distance between the Earth and the Sun is closer when the axis of rotation is tilted in relation to the revolution and seasonal changes due to changes in the orbital radius of the Earth. In addition, there have been types of explanations such as seasonally changing meridian altitudes related to the rotation of the Earth but no change in the location of the Sun. Based on the results of the analysis, we discussed the lack of experience in constructing an explanatory system of specific phenomena using scientific knowledge, lack of observational experiences about natural phenomena, and lack of exposure to other explanatory systems that cause cognitive conflicts. We hope that it will be concrete and practical help to improve the understanding of pre-service teachers in the science domain of primary teacher training program.

Objectives : This study aims to grasp the principle of the Won Bang supplementation and draining method as mentioned in the 『Lingshu·Guanneng』 and the 『Suwen·Bazhengshenminlun』, which have contrasting properties. Methods : The texts in each chapter were analyzed to understand the supplementation and draining principle that matches the meanings of round[won,員] and angular[bang, 方]. Especially in the case of the chapter 「Bazhengshenminlun」, a hypothesis was drawn upon the relationship between the abstract explanation of the round[won,員] and angular[bang, 方] and the actual manipulation technique. This hypothesis was tested against other texts and annotations for further discussion. Results & Conclusions : The expressions 'bang[angular, 方]' and 'won[round,員]' refer to the same meanings in both chapters, as 'to be upright' and 'to be smooth,' respectively. The difference between the two chapters is that in the 『Lingshu·Guanneng』 the standard for Won Bang is the needler's movements, while in the 『Suwen·Bazhengshenminlun』, it is the patient's breathing. Moreover, while in the former the subjects of supplementation and draining are clearly divided into healthy qi and exterior pathogenic qi, in the latter the subject of manipulation is the deficiency and excessiveness caused by deviation of the healthy qi, thus making the subject of both supplementation and draining healthy qi. Based on these findings, we can conclude that the supplementation and draining of needling is divided into two methods; separating the healthy and pathogenic qi and manipulating the deficiency and excessiveness of healthy qi within the body.

This study analyzed the written texts of textbook and the teacher's discourse explaining 'the relationship between quadratic functions and quadratic equations' in the 9th grade high school mathematics class. Data consisted of the lecture recordings and the textbooks were analyzed based on the Halliday's systemic functional linguistics. According to the results, the written texts of the textbook used lexico-grammatical strategies such as generalization using hyponomy of meanings, mathematical objectification through nominalization and materialization of meaning through change in themes to compose mathematical concepts. The textbook generalized from an example in the description of formulating mathematical concepts, and in this process the organizational interactions of discourse-semantic level and lexico-grammartical level appeared. On the other hand, the teacher's doscourse appeared the change in transitivity and the addition of the reasons and the process. Also the teacher used explanation process of formulating the relationship between quadratic functions and quadratic equations. The linguistic characteristics of the teacher were linguistic implication and omission of lexemes due to contextual ommission. And there was no use of structural lexico-grammatical resources that influence the discourse-semantic level. This results provide a new framework for analyzing mathematical discourse, and suggest the lexico-grammatical strategies that can be used to explain mathematical concepts by teachers in math classrooms.

Objectives : In this article, an analysis of the changing theory(從化理論) of Sameumsamyang(三陰三陽) and Pyobonjung(標本中) in some important medical books, and the historical contexts of those is investigated. Methods : Primary literatures about the changing theory were searched by key words of Sameumsamyang and Pyobonjung in main medical texts, and then analyses and selecting of significant documents have followed. Results : The application of the changing theory to clinical treatment has been mainly done in the process of comprehension and practice about "Sanghanron(傷寒論)". Getting out of simple explanation about meaning of paragraphs in "Sanghanron", the clinical application has been expended to detail drug instruction and prescription managements. Conclusions : The changing theory of Sameumsamyang and Pyobonjung has been actively applied to supporting clinical treatment historically, not recognized merely as a ideal theory.

Objective : Through the comparison of the Eumyang(陰陽) theory between Hwangjenaegyeong(黃帝內經) and Juyeok(周易) Gyesajeon(繫辭傳) written by Gongja(孔子), the philosophical background of Hwangjenaegyeong(黃帝內經) and the position of Eumyang theory in the ancient academic society can be clearly understood. Method : The similarities and differences of the Eumyang theory in Hwangjenaegyeong(黃帝內經) and Juyeok(周易) Gyesajeon(繫辭傳) are categorized and analyzed comparing both texts. Results & Conclusion : Hwangjenaegyeong(黃帝內經) and Juyeok(周易) all recognized Eumyang movement as the most important and basic principle of the change of the universe. In the relationship between Eum(陰) and Yang(陽), the key of harmonization of them is to keep and practice the virtue of each others. The plentiful expression of Juyeok(周易) Gyesajeon(繫辭傳) about the relationship of Eumyang is helpful to understand and apply the concepts of Eumyang to daily life. The other hand, Hwangjenaegyeong(黃帝內經) as medical text, concentrates upon the explanation about the movement and circulation of Gi(氣) between Eum and Yang.

Using eighteen texts from various genera of present-day Japanese, I collected phonologically reduced forms frequently observed in conversational Japanese, and classified them in search of a unified. explanation of phonological phenomena. I found 7,516 cases of reduced forms which I divided into 43 categories according to the types of phonological changes they have undergone. The general tendencies are that deletion and fusion of a phoneme or an entire syllable takes place frequently, resulting in the decrease in the number of syllables. From a morphosyntactic point of view, phonological reduction often occurs at the NP and VP morpheme boundaries. The following findings are drawn from phonetical observations of reduction. (1) Vowels are more easily deleted than consonants. (2) Bilabials ([m], [b], and [w]) are the most likely candidates for deletion. (3) In a concatenation of vowels, closed vowels are absorbed into open vowels, or two adjacent vowels come to create another vowel, in which case reconstruction of the original sequence is not always predictable. (4) Alveolars are palatalized under the influence of front vowels. (5) Regressive assimilation takes place in a syllable starting with [r], changing the entire syllable into a phonological choked sound or a syllabic nasal, depending on the voicing of the following phoneme.

Purpose - The current study will provide a cause-effect explanation that will reinforce the existing perception that effective communication fosters organizational communication. The findings will also empower organizations with information on why they must polish their communication strategies. Research design, Data, and methodology - This study has collected numerous textual datasets through 'Qualitative Content Approach' (QCA). The author of this research had a responsibility to develop comprehensible methods for categorizing and drawing inferences from raw data in addition to data collecting tactics that may effectively solicit representations. Result - The current study ultimately concludes that effective communication is the most cost-effective tool for motivating employees. Two-way organization communication allows employees to communicate the hardships they encounter in their job. The result of this is adjustments that are geared towards eliminating work-related challenges. Total four suggestions exist for practitioners in the main texts on 'Results' section. Conclusion - According to theoretical research, organizational commitment is anchored on the ability of an organization's leadership to communicate the organization's values to lower-level employees. Moreover, the findings reiterate the importance of creating leadership systems that embody an organization's core values. Communication systems that engender this ensure that management discloses the rationale for their business and corporate strategies to employees.

Objectives : The theory of Latent Qi Wenbing and its counter-arguments were examined in terms of each argument's theoretical background and logicality. Methods :Arguments for and against the theory of Latent Qi Wenbing in medical texts were examined closely. Results & Conclusions : Each doctor's theory on Latent Qi Wenbing was examined in the following four aspects. First, to what kind of pathogenic qi was the patient exposed during Winter? Second, how did the pathogenic qi affect the body in the time of exposure? Third, how did the latent qi change over the Spring and Summer within the body? Fourth, what kind of weather generates the disease during Spring and Summer? Each argument had different opinions on each aspect. The main argument made against the theory of Latent Qi Wenbing is that it is impossible for the pathogenic qi that initially damaged the body to stay latent until it generates disease after some time. The theory of Latent Qi Wenbing could be assumed to have been created based on situations in which such explanation was adept. Factors that contribute to this theory could be explained through the condition of the healthy qi, state of cultivation during the past season, and constitutional factors.

The objectives of this study was to apprehend the displaying components by comparing and analyzing the ten types of construction textbooks used in Technical high schools by elaboration theory by Ferigeluth, and to supply preliminary data for the following revising textbooks. To achieve them, first, comparable units were excerpted by analyzing between the national textbooks of 7th curriculum and the new revised curriculum used in Technical high schools. Second, each five types of 7th and new curriculum textbooks were compared and analyzed by seven requisites in the Elaboration theory by Reigeluth. As the results of the study, first, elaborating process like conceptual, procedural, and theoretical elaboration has been applied to the different subjects according to their properties. Second, cognitive strategy activator among the seven strategies was widely used. Whereas, analogy was not applied to all the ten types of the text books. In addition, Learning prerequisite sequence was presented with only simple picture and explanation, and it was inadequately used in practice. Third, summary was more used in 7th curriculum text than the new revised text. Fourth, six strategy components were widely used to all texts except construction and materials in the five types of texts. Lastly synthesis of theory and practice was more used than summary in theory subjects and learner control was more used in the subject of the synthesis of theory and practice.

Scientific explanation is composed of various representations such as texts, diagrams, and graphs, and each representation contributes to expanding scientific meaning by connecting similar but slightly different meanings as a 'mode'. Based on this perspective of social semiotics, we aimed to identify the characteristics of meaning formation demonstrated in students' science writing (verbal mode) and science drawing (visual mode) and to discuss the pedagogical use of multimodal representations. To that end, 18 science drawings and 18 scientific writings constructed by science-gifted elementary students on air pressure were collected. The characteristics of the drawn and written explanations were then analyzed from the affordance perspective in social semiotics. In science drawing, students showed a tendency to use the affordance of the visual mode to infer concrete changes from the particle view, such as the movement of air particles, the number of air particles, and the collision of particles. In science writing, students used the affordance of the verbal mode mainly to infer the causal relationship between the concept of air pressure and other related factors at an abstract level. Based on those results, we discuss the educational implications and provide concrete examples of how to use the unique affordances of each form to complement one another.
