Since 1945, geography textbooks of South Korea and North Korea have been developed differently. Taking both geography textbooks of South Korea(printed in 1996 and 1997) and them of North Korea(printed in 1995), this study compares and analyse geography textbooks of South and North Korea systematically, then to show their likeness and difference. Results of this study are as follows: First, Most of contents in South Korean textbooks consist of explations and many tables, graphs and photographs leading to inquiry activities, whereas those in North Korean textbooks consist of mostly sentences that explain topics, diagrams and sketches. Second, Geographical education in South Korea puts strong emphasis on human geography and regional geography, whereas that in North Korea does strong emphasis on physical geography, economic geography and education of cartography. Third, The geographical words of South Korean textbooks contain words written in Chinese character and words of English origin, whereas Those of North Korean textbooks do many pure Korean words.

The purpose of this study was to investigate the effects of game-based-digital textbook on the basic arithmetic abilities and the task attention of students with mental retardation. To do this, 38 students with mental retardation participated and were assigned to the three groups. The first group only used the traditional text book, the second group only used the game-based-digital textbook, and the third group used both the traditional textbook and the game-based-digital textbook. The third group using both the traditional textbook and the game-based-digital textbook revealed more higher improvement than the other two groups in the basic arithmetic and the task attention.

The purpose of this study was to examine the understanding of contents and the convenience of use of the DNR animation mobile electronic informed consent. The subjects in this study were inpatients of long-term care hospital. As for data analysis, a statistical package SPSS 21.0K was employed. The findings of the study were as follows: First, DNR choice was 33.0%, CPR choice was 54.0% in case of the outbreak of cardiac arrest. Their principal diagnosis made statistically significant differences to their choice of DNR and CPR. Second, they got 2.50 in the understanding of the content of the DNR electronic informed consent, and got 2.37 in the convenience of use. Given the findings of the study, the DNR animation electronic informed consent is expected to help patients to have a better understanding of contents, to make their decision to choose DNR or CPR, and to sign the DNR informed consent forms themselves.

One of the issues with the textbooks pertinent to the current study is whether or not the Universal Design for Learning (UDL) factors have been dealt to satisfy students with different aptitudes in learning the core objectives of the lessons. This study develops a modified version of the UDL analysis criteria from the cross curricular criteria to language teaching and learning and uses it to analyze the sequence of digital English textbooks to investigate the descriptive statistics of the UDL factors in the new textbooks. The result shows that the textbook is designed most favorably to the students with the talent of linguistic aptitude and less favorably to the students with other types of aptitudes. The sequence analysis shows that sentence/word length and appearance of new words are incrementally sequenced as students advance upper grades. However, the syntactic complexity of middle school curves up steeply which is different from the elementary school textbooks. The UDL analysis will provide learning factors to consider when designing digital English textbooks to cover different aptitudinal groups.

In this paper, based on the results of analysis on types and strategies of estimation in measurement in the textbooks according to 2009 revised elementary mathematics curriculum, the following four implications are suggested for curriculum development and textbook development for a later date. First, it is necessary to reconcile curriculum and textbooks in contents for estimation in measurement. In 2009 revised elementary mathematics curriculum, only estimation in length, estimation in capacity, estimation in weight, estimation in angular measure are presented. However, estimation in time and estimation in area are presented in textbooks. Second, it is necessary to introduce various strategies for estimation in measurement. In teacher's manual, three strategies like using referent, chunking, unitizing are illustrated. But in textbooks, such strategies are not illustrated properly. Third, the meaning of the 'estimate' need to be clarified. In textbooks, 'estimate' are used also in other contexts. Fourth, it is necessary to clarify whether or not to deal with estimation in time, estimation in area, and estimation in volume in the school curriculum. In 2009 revised elementary mathematics curriculum, estimation in time, estimation in area, and estimation in volume are not mentioned explicitly.

Nowadays, domestic construction companies make an effort to share knowledge and experience accumulated while conducting a project. One way of improving knowledge sharing is to develop specifications which are linked to the expert's knowledge and experience based on the specification classification. Therefore, the purpose of this paper is to review the current domestic specification system and develop the specification linked to the construction lessons learned database. It is expected that the proposed specification system will support the decision making process by effectively providing the knowledge and solution.

Computational studies on the hydrodynamic behavior of the forward-sweep inducers for the rocket-engine turbopump are presented in comparison with the conventional backward- sweep inducers. In the present study, two kinds of forward-sweep inducers are designed and numerically investigated. Forward-sweep inducers have bigger tip solidity compared to backward-sweep inducers even with shorter axial length due to their forward-sweep leading edge profiles. It is shown that back flows at the inlet decreases dramatically for forward- sweep inducers. And the low pressure region at the back flow are also decreased, which is assumed to promote the suction performance of the inducers. It seems that the hub located upstream of the tip at the leading edge induces pre whirl at the inlet blade tip for the backward sweep inducer. And this pre whirl leads to the big back flow.

General and subject guideline for new curriculum are confirmed and plan to announced on September 2015. The development of instructional materials according to them will proceed. Because textbooks have the role and function to determine and control the direction and scope of teaching and learning, Textbook plays a very important role in the situation where teachers and students meet. Thus we get a significant effect depending on the structure of textbook. In this study, we analyzed differences of detail learning content according to high school textbooks focused on utilizing of definite integral. After creating the questionnaire based on it, The survey was conducted targeting for 369 high school mathematics teachers belong to 14 education offices of cities and provinces are polled out by accidental sampling method. Analyzing the results of the survey, We searched various teaching and learning method that arise due to differences of detail learning content according to high school textbooks and thereby it explored the impact on students' mathematics learning. Through this, Our intention is to offer implication about the structure of textbook detail learning contents and to derive the improvements about textbook compilation system.

The purpose of this paper is to examine how European textbooks reflect Seoul nowadays. The study focuses on the trend of textbooks in main European countries, such as England, France, Spain, Italy, and Germany. They tend to describe Seoul as one of the mega cities with urban problems, and introduces the city as an economic center which is responsible for interaction with other mega cities. Besides, Seoul is also described as less competitive city compared to others, and its history and cultural resources are not paid attention. Despite everything, it is fortunate that there are very few errors in descriptions of Seoul. In future I expect that descriptions of Seoul in European textbooks are enhanced in not only economic aspects of Seoul but also historic and cultural aspects of Seoul and then European textbooks get more reliable contents to inform Korea.
