In the purpose of suggesting the necessity and proper method of providing the standard reference material for acquiring the aircraft pilot license, this study provides the FAA and ROKAF case study, and positively analyzes the materials of 178 pilots and student pilots who acquired the aircraft pilot license. The result of case study shows that compared to the case of Korea which the restriction on the standard reference material providing exists, the FAA(Federal Aviation Administration) and ROKAF are currently providing the standard reference material. Additionally, the result of positive analysis indicates the fact that the necessity of standard reference material providing is well recognized and its importance also found to be remarkably high. These results represent that the standard reference material providing is necessary for training competent aircraft pilots. Also, this will mitigate the current shortage of aircraft pilots due to the rapid growth of air transportation industry, and this will play an important role in preventing diverse aircraft-related accidents.

The study investigated and analyzed the middle school student's science textbook learning methods and strategies. The Preferred Mehtod of Study (PMOS) and a clinical interview method were utilized. Results indicate that there is a meaningful and significant positive correlation between the number of times students read a chapter of the science textbook and their science grade point. Students do not tend to alter learning strategies dependent upon the subject matter studied, but easily alter stratgies dependent upon the types of the test. Most students could not construct "organiztional tools" such as a summary, a chart, a talbe, or a figure when they study textbook, but might pursure and prefer only one method when they choose their learning strategise. Very few students (less than 1%) among those queried consciously try to connect between prior knowledge and new concepts in the textbook. Even though students choose the textbook for learning science in the beginning, they prefer to stick to reference and exercise materials. Therefore, detailed and direct studise of the student's learning methods and strategies, as well as research on cognitive psychology and motivational psychology, are necessary in order to develop a new textbook with student-based learning materials. By understanding the student's konwledge level through investigation of his or her learning style, an effective science education program can be realized. Finally, the role of the textbook as a tezching/learning material can be maximized by investigating and understanding the student's learning method and strategy with emphasis on reciprocal action between textbooks.

The purpose of this study is to explore the child education experiences of married female students who left their children in their home countries. This study consists of two questions. First, what is the meaning of the child in home country for married female students to their foreign student's life? Second, how they do the child education? For this study data was collected from March to May, 2016 through in-depth interviews with 6 married female students who left their children in their home countries to further their studies in Korea. Then, the data was analyzed their cases were analyzed. First, for married female students their children are always in the first place during their life as a foreign student in Korea. Second, their children play a great role in their foreign student life. Third, the child makes them to be exemplary student in their foreign student's life. In addition, children's education is entrusted to those who are raising them in their home country. However, when big decisions have to be made, it is done by the mother. Also, because they feel sorry towards their children they actively reflect the views of the children. Moreover, they often check everything about their children through SNS. Through this study, we expect to less school life's difficulty of foreign married students and it will be helpful material for them to graduate their foreign students' life. The purpose of this study is to explore the child education experiences of married female students who left their children in their home countries.

This study focused on the practical research needed to improve elementary school science lesson plans. Specifically, a video clip-based pedagogical reasoning activity that included elementary student misconceptions was presented and the influences of this activity on preservice teachers' science lesson planning were assessed. First, the eight preservice teacher participants were asked to write a lesson plan for a dissolution and solution unit, after which a first semi-structured interview was conducted. Then, the participants participated in a video clip-based pedagogical reasoning activity. Based on the activity results, the participants revised their previously planned lessons, and second semi-structured interviews were conducted. The data from the preservice teachers' lesson plans and interview transcripts were analyzed using a constant comparative method to investigate the lesson plan changes. It was found that after the video clip-based pedagogical reasoning activity, the preservice teacher tightened the activity or changed the material to understand the students' thinking processes. In addition, they supplemented their goals and assessment criteria to accommodate the diverse students' thinking. Some also specified motivational strategies that considered student interests, motivation, and possible misconceptions. However, some preservice teachers still set goals that did not sufficiently account for student misconceptions and some planned the student assessments based only on the learning goals rather than the students' thinking. The few preservice teachers were able to develop motivational strategies that considered interest, motivation, and misconceptions. The preservice teachers claimed that they had difficulty predicting the misconceptions and connecting these to the lesson content. Discussions were then held to assist the preservice teachers to consider possible student misconceptions when planning their lessons.

We have been received questionnairs on the general characteristics and cognition of radiotechnological students, instruction which they hope, and the present processing actural states of instruction to 610 numbers of 2, 3 years radiotechnological students in korea. We have been perceived the actural states of radiotechnological instruction by the results of questionnaires, therefore, the imperfections of student's contentment, lack of instruction plan and audio-visual material's practical use, insufficient of study activities on instruction process, lack of clinical adaptation and practice of lecture evaluation were founded. We propose the solving method of these problems as the improvement of instruction. It is necessary for the will and effort of college and teacher to practices these problems.

In the comprehension of English texts, Korean students generally try to translate English into Korean in accordance with the word order of Korean language. As a result, the comprehension of English texts is made in a regressive way, which results in slower reading. In order to enhance the reading speed, it is necessary for students to practice progressive reading. Also, while reading English texts, most readers' eyes tend to look at one word at a time, which actually cuts down on the reading speed. Reading by the sense group of as many words as possible at a glance, however, can help a reader more efficiently in less time. This research aims at developing the Powerpoint program for progressive reading by the sense group according to the student's level. In this program, as for methodology, the technique of rooking it fade-away is introduced to force a reader's eyes to move fast. Through this technique, it is possible to make a line of the texts disappear on the screen and make another line appear, which enables a reader to sweep the words across each and every line of the reading material smoothly without regression.

This paper studies the field applicability of the Special Chemical grouting Method(SCM) in reinforcing and reducing permeability of the back of an existing continuous wall. SCM uses double rod which imposes intermediate pressure$(981\sim9,810kPa)$ to disturb, cut, discharge, and mix the ground. It is observed that a bulb is formed by using cement paste and environmentally friendly injection materials with minimal alkali leaching. Uniaxial compression tests, test for chemical properties and fish poison test are performed. Test results indicate that the method results in higher durability, less leaching through use of the environmentally friendly injection material, and faster mobilization of the strength. In addition, field tests confirm the formation of the bulb and the seepage cutoff wall.

Manufacturing fabrics from dissolving cellulosic pulp is increasing in these days. For making high quality of cellulose-based fabrics, control of cellulose DP (degree of polymerization), its alpha cellulose content, its brightness, and its crystallinity are important. To process the cellulosic raw material, refining of cellulosic fibers is essential, and it is important to know if refining affects those important cellulose properties. The effects of PFI mill and Valley beater refining on the alpha-cellulose content, cellulose DP, crystallinity, and paper mechanical properties of wood and two different cotton fibers were studied. The results showed that PFI mill refining rarely affected those properties. Fibers refined by a Valley beater displayed a small reduction in fiber length in comparison with those refined by a PFI mill. However, the Valley beater refining method produced almost no changes in cellulose properties, either. The refining process seemed to have very little effect on the cellulose DP, crystallinity index, or alpha-cellulose content until the freeness decreased to around 300 mL CSF for wood and 100 mL CSF for cotton fibers, respectively. There were also no differences in tensile strength development in two refining methods.
