This study is to review the content organization and developmental ways of the unit on the mixed calculations and explore the alternatives on the basis of students' responsive examples and error patterns with relation to the mixed calculations, mnemonics of PEMDAS and historical context with relation to the order of operations. Then I analyzed the textbook and manual for teachers of the unit of mixed calculations of fourth grade and improvement about teaching the mixed calculations. First, I pointed out illogical connection between practical problem and rules of order of operations. Second, I suggested constructing a textbook by considering conventional character of order of operations. Third, I pointed out the importance of structural understanding of an expression of mixed calculations and various strategies with relation to teaching and learning. This study is suggestive for textbook development of the mixed calculations.

Background : It was not enough to apply three kinds of syndrome differentiation in our oriental medical textbook to tremor's treatment according to reports of Korea and traditional medical textbook of China. Objective : To investigate syndrome differentiations by types of diseases related to tremor through Chinese journals review and to suggest adding possible syndrome differentiations. Methods : Literature search was performed using China Academic Journal (CAJ), the search engine of China National Knowledge Infrastructure (CNKI) from January 1994 to December 2009. Searching key words were Chinese characters in combination meaning tremor, paralysis agitans, and syndrome differentiation. We included all types of articles that explained or referred to definite syndrome differentiations. The symptoms and oriental medications by syndrome differentiation in selected articles were extracted and summarized. Results : 56 Chinese journals were ultimately selected. 37 kinds of syndrome differentiations about tremor were investigated, which included dual deficiency of qi and blood (氣血兩虛) quoted 31 times, liver-kidney yin deficiency (肝腎陰虧) 23 times, liver-kidney deficiency (肝腎不足) 21 times, and phlegm-heat stirring wind (痰熱動風) 20 times. 37 kinds of syndrome differentiation could by group into eight types, such as liver-kidney yin deficiency (肝腎陰虧), dual deficiency of qi and blood (氣血兩虛), phlegm-heat stirring wind (痰熱動風), heart deficiency and spirit weakness (心虛神弱), blood stasis due to qi stagnation (氣滯血瘀), sea of marrow deficiency (髓海不足), liver qi depression (肝氣鬱結), and liver yang transforming into wind (肝陽化風). Conclusion : We suggest that the syndrome differentiations of tremor, such as heart deficiency and spirit weakness (心虛神弱), blood stasis due to qi stagnation (氣滯血瘀), sea of marrow deficiency (髓海不足), liver qi depression (肝氣鬱結), and liver yang transforming into wind (肝陽化風), can be added to liver-kidney deficiency (肝腎不足), dual deficiency of qi and blood (氣血兩虛), and phlegm-heat stirring wind (痰熱動風) of the textbook. Further systematic research will be needed on them.

Background: Elements of informed consent including capacity, disclosure, understanding, voluntariness, and permission of the participant, are all crucial for clinical trials to be legally and ethically valid. During the informed consent process, the patient information leaflet is an important information source which prospective research subjects can utilize in their decision-making. In the adequate provision of information, KGCP guideline necessitate 20 specific items, as well as the use language that individuals can understand. This study measures the vocabulary level of patient information leaflets in an effort to provide an objective evaluation on the readability of such material. Methods: The word difficulty of 13 leaflets was quantitatively evaluated using Kim kwang Hae's vocabulary grading framework, which was compared to the difficulty level of words found in the $6^{th}$ grade Korean textbook. The quantitative outcomes were statistically analyzed using chi-squared tests and linear by linear association for ordinal data. Results: There was a statistically significant difference between the vocabulary level and frequency of words in leaflets and the 6th Korean textbook. The leaflets were on average 260 sentences and about roughly 15 pages long, including lay language (easier or equal to language used in primary school) of around 12% less; technical language of around 4.5% more. As the vocabulary grades increase, there was a distinct difference in vocabulary level between Korean textbook and each information leaflet (p < 0.001). Conclusion: Patient information leaflets may fail to provide appropriate information for self-determination by clinical trial subject through the difficulty level of its wording. Improvements in the degree of patients' understanding and appropriate use of information leaflets are collaboratively equipped to strengthen patient's autonomy and therefore guaranteeing participant's rights.

The fraction concept consists of various meanings and is one of the abstract and difficult in elementary school mathematics. This study intends to find out the implication for introducing the fraction concept by comparing mathematics textbooks of Korea and Singapore. Both countries' students peformed well in recent TIMMSs. Some implications are as follows; The term 'equal' is not defined and the results of various 'equal partitioning' activities can not easily examined in Korea's mathematics textbook. And contexts of introducing fractions as a quotient and a ratio are unnatural in Korea's mathematics textbook in comparison with Singapore's mathematics textbook. So these ideas should be reconsidered in order to seek the direction for improvement of it. And Korea's textbooks need the emphasis on the fraction as a measure and on constructing fraction concept by unit fraction.

In this research, Problem Solving and Programming - the chapter common among four different types of middle school informatics textbooks based on the national curriculum revised in 2015 - was analyzed to measure its effects on cultivating students' curiosities. Romey's analysis was applied to these textbooks on four analytic elements - texts, data, activities, and evaluation. The results showed that each type of textbook showed a differing degree of encouraging students' inquisitive tendencies on each analytic element; two out of four textbooks were well developed for texts, three for data, three for activities, and all four for evaluation. In terms of Romey's index points, two textbooks had low indexes of texts, such as 0.185 and 0.413. Data indices were extremely low in one textbook at 0.147. Three of four textbooks exhibited high indices of activities at 0.969, 0.608 and 0.627. Evaluation indices were high in all four textbooks at 1.333, 1.268, 1.274, and 0.764. These revised textbooks overall showed higher metrics than the previously designed textbooks with regards to promoting students' inquisitive nature.

Recently, research on edutech, which combines education and technology in the e-learning field called learning, education and training, has been actively conducted, but it is still insufficient to collect and utilize data tailored to individual learners based on learning activity data that can be automatically collected from digital devices. Therefore, this study attempts to detect questions in textbooks or problem papers using artificial intelligence computer vision technology that plays the same role as human eyes. The textbook or questionnaire item detection model proposed in this study can help collect, store, and analyze offline learning activity data in connection with intelligent education services without digital conversion of textbooks or questionnaires to help learners provide personalized learning services even in offline learning.

Measurement in elementary school mathematics is one of the mathematical concepts that is directly used in real life. This study is based on the fact that mathematics textbooks for 3-4 and 5-6 graders were developed as the government designed and authorized textbooks and the general measurement instruction process is condensed and presented considering the limitation of the textbook's space for the capacity and weight. Its contents were analyzed. The results are as follows. The contents of authorized textbooks and government designed textbook are different in detail but similar overall in comparative activities, recognition, and situation of the need for the introduction of standard unit and estimation activities. Through this, it is proposed that efforts are needed to reform national textbook policies and develop textbooks that can highlight the meaning of each measurement activity and focus on students' activities.

The researchers set up a research question to find out how to teach the concept of a right triangle through classification activities after listening to the conversations of fellow teachers about the recently revised textbooks. First, a questionnaire was created to confirm the objectivity of the research problem, data were collected through online and offline, and interviews were conducted with some of the respondents. As a result, it confirmed that there was a considerable difference in the perception of the research study about the direction of revising the curriculum called 'student participation centered' and 'the possibility of achieving the learning objective'. Then, we analyzed the critical interpretations used in the third grade math textbook Lesson 2. 'Plane Figure' part 4 and 5. Finally, by analyzing the results of the recognition analysis and textbook analysis, we proposed two learning methods which can link the triangle classification activity and the right triangle concept. Based on the results of the research, we obtained suggestions that a teaching should be made regarding that the classification process may be changed according to the student's prior knowledge and the process of classification activities may be different according to the viewpoint and classification criteria.

As an effort to realize the results of last two years of study, this study had three distinguished purposes: 1) confirming whether some requests for corrections had been accepted or not 2) making a list of possible errors found in newly written textbooks and asking to fix them, and 3) classifying forest related contents identified in the textbooks according to the 150 topics included in information material, so called Forest IQ 200. Among 94 errors associated trees, forest or forest education, only thirteen of them were found to be fixed according to the request made in previous study of 2008. Especially, most of the fixed errors were identified to be in natural and social science subject textbooks and nothing was found in art and language areas. Total of 1,320 forest related items were found in the textbooks at the level of kindergarten to 10th grade(freshman in highschool). Korean student was expect to have a chance to learn forest related items 1.64 times a week for 10 years(First to 10th grade). Analyzing 1,109 contents in terms of four topic areas of forest education, the forest culture area was found to have most content of 348 including painting and recreation. Some suggestions were made to make school forest education better, and publishing the forest textbook for elementary schools was one of them.
