The purpose of this study is to investigate the impact of argument-based modeling strategy using scientific writing on student's modeling ability. For this study, 66 students (three classes) from the 7th grade were selected and of these, 43 students (two classes) were assigned to two experimental groups while the other 23 students (one class) were assigned to comparative group. In the experimental groups, one group (22 students) was Argument-based multimodal Representation and Modeling (AbRM), and the other group (21 students) was Argument-based Modeling (AbM). Modeling ability consisted of identifying the problem, structuring of scientific concepts, adequacy of claim and evidence and index of multimodal representation. As for the modeling ability, AbRM group scored significantly higher than the other groups, AbM group was significantly higher than comparative group. The four sub-elements of modeling ability in the AbRM group was significantly higher than the other groups statistically and AbM group scored significantly higher than comparative group. From these results, the argument-based modeling strategy using scientific writing was effective on students' modeling ability. Students organized or expressed the model and evaluated or modified it through the process of argument-based modeling using scientific writing and the exchange of opinions with others by scientific language as argument and writing.

When you present a medical scientific paper or give a lecture in English, It is important to visit your presentation room in advance to gain familiarity with the controls and the computer. You can check how to use the mouse or laser pointer and determine where the microphones are. You should meet the Chairman and introduce yourself. You may ask the Chairman any questions you have. I am confident this strategy will work for beginners because they are usually nervous before their presentations. Most Chairmen prepare one or two questions for the presenters to stimulate discussion. Speaking with the Chairman also allows you to determine the type of English that he or she speaks (i.e., French-English, Spanish-English, and British-English). You need to be comfortable with the Chairman's English before the presentation because the Chairman will repeat the questions for you when you do not understand a question from the audience. Although I have given a number of lectures and moderated many scientific sessions and symposiums in English over the past 20 years, it is still difficult and stressful for me to do these in English because English is not my first language. To overcome the problems, I have written down the questions and useful English expressions that I have received during or after my presentation because I found them helpful for my next presentation. I hope the examples will be of great help to you.

The purpose of this study was to get an implication on teacher education program, by exploring the difficulties pre-service elementary teachers have with their science lessons. 37 pre-service teachers were requested to write an anecdote about their science lessons during their 4 week practicum. By analyzing these anecdotes, the difficulties were grouped into several categories by the researcher, and then reconfirmed by the pre-service teachers themselves. The result showed that there were far more difficulties with practical work (cases: 48), than with content knowledge teaching (cases: 17). Among practical work related difficulties, the most frequent cases were: 1) when they have unexpected result different from scientific theory (cases: 10), 2) when they teach process skill and usage of lab equipments (cases: 8), and 3) when they do not have enough preparation for practical work (cases: 7). Unlike the result of preceding research on secondary pre-service teachers, there was no affective aspect problems. These difficulties also can be divided into 'problems' and 'dilemmas'. Whereas 'problems' can be settled by removing obstacles, 'dilemmas', a conflict-filled situation, require choices between competing values or aims. The use of scientific language, the decision on the level and amount of knowledge they teach, and disposal of unexpected experiment results caused such dilemmas in science lessons. The research results imply practical work should be more strengthened in the elementary teacher education program. And both teacher educators and pre-service teachers need to understand that practical teaching is a complex enterprise accompanying some 'dilemmas'. The role of science teachers as managers of dilemmas could be considered.

Text mining has become an important research method in biology, with its original purpose to extract biological entities, such as genes, proteins and phenotypic traits, to extend knowledge from scientific papers. However, few thorough studies on text mining and application development, for plant molecular biology data, have been performed, especially for rice, resulting in a lack of datasets available to solve named-entity recognition tasks for this species. Since there are rare benchmarks available for rice, we faced various difficulties in exploiting advanced machine learning methods for accurate analysis of the rice literature. To evaluate several approaches to automatically extract information from gene/protein entities, we built a new dataset for rice as a benchmark. This dataset is composed of a set of titles and abstracts, extracted from scientific papers focusing on the rice species, and is downloaded from PubMed. During the 5th Biomedical Linked Annotation Hackathon, a portion of the dataset was uploaded to PubAnnotation for sharing. Our ultimate goal is to offer a shared task of rice gene/protein name recognition through the BioNLP Open Shared Tasks framework using the dataset, to facilitate an open comparison and evaluation of different approaches to the task.

Robot control involves advance programming, scientific and high technology. The systematic and methodological aspects of robot controls often results in having superficial control design problems that can negatively affect the robot application, usability and appeal. User friendly interface of robot control is extremely advantageous and more attractive. To illustrate, the application of medical robot is usually handled by clients who have little background in advance programming language. Thus, it would be difficult if the client needs to use programming language to control the robot. It would justify better if the robot control is presented in a meaningful interface to the client. This way the robot application would be more natural and user friendly. This paper describes the method of developing the user interface for web based communication to control an internet robot named Tarou. The web based communication tasks involves three levels. The first one accommodates on the client sending commands to robot through the internet. The next communication level relates to the robot receiving the commands sent by the client. The final communication level generates on sending feedback on status of commands by the robot to the client. The methodology used here can be elaborated in four hierarchical steps; identify user needs and robot tasks, identify the enhancing tag reference used by the server, induce the tag into HTML, present the HTML in attractive user interface as the client control panel.

본 연구는 결속장치(cohesive devices)가 과학텍스트의 읽기 속도와 내용 이해에 끼치는 영향에 대해 연구하였다. 연구의 목적을 위한 실험을 통해서 먼저, 텍스트의 문단별 읽기 시간을 측정하여 온라인 처리 과정을 검토하였고, 둘째, 회상과 재인 검사를 실시하여 오프라인 상태에서의 이해도를 조사하였다. 이 연구의 재료로 사용된 텍스트는 번개 생성과정에 대한 과학텍스트로서, 반복, 지시사, 정박(anchoring), 인과적 접속사 등의 결속장치를 이용하여 응집성(coherence)의 강도를 높고, 낮게 조작하였다. 실험 결과, 결속장치가 길속장치의 종류와 지엽적 응집성의 강도에 따라 과학텍스트 읽기와 이해에 선택적으로 영향을 끼친다는 것을 발견하였다. 첫째, 인과적 접속사는 읽기 시간에는 영향을 주지 않는 반면, 이해를 촉진했는데, 이 긍정적 효과는 과제의 종류에 따라 다르게 나타났다. 즉, 회상 검사 결과에서는 인과적 접속사가 쓰인 모든 문단에서 유의한 차이가 나타났으나, 재인 검사에서는 유의한 차이가 부분적으로만 나타났다. 둘째, 반복 결속장치는 다른 결속장치와 같이 발생할 경우에만 읽기 시간과 이해를 부분적으로 촉진하는 것으로 나타났다. 셋째. 정박 결속장치의 영향은 읽기와 이해 두 처리 과정에 모두 선택적으로 영향을 준 것으로 나타났다. 인과적 접속사와 함께 쓰인 문단의 경우에는 회상 검사에서만, 반복 결속장치가 함께 쓰인 문단에서는 회상, 재인 검사에서 모두 긍정적 영향을 준 것으로 관찰되었다.
