The purpose of this study is to find methods that allow learners to improve their listening comprehension skills. To do this, we have divided this article into three parts. In the first part, we analyzed studies focus on the skill of listening. In the second part, we are dedicated to the process steps in the study of listening comprehension. In the last part, we tried to demonstrate this by examples according to the difference in levels of learners. More specifically, we applied the questionnaires according to a typological difference. Most teachers recognize the importance of listening to complete the language proficiency of learners. Nevertheless, there are many difficulties in implementing effective methods for improving listening comprehension skills. In addition, there is a strong tendency not to consider listening as an autonomous field, but as a part of oral proficiency. In addition, we can not ignore the importance of the method of application, because it can motivate learners to both concentrate on their studies and to voluntarily participate in the course. In this sense, the Professors and teaching staff can use the examples of DELF to establish concrete goals for the course of listening. It is difficult to confirm that this study is the most effective way with regard to the methodology, but we hope it may be useful to improve the skills of listening comprehension French learners.

This study investigated the Present status of laboratories for experiment and practice, and analyzed teachers' recognitions on experiment and practice for Home Economics area of a Technology and Home Economics curriculum according to majors of teachers. Questionnaires were mailed to middle school teachers who taught home economics part and they answered on the web. 220 replies were used for the final analysis. The findings were as follows: First, the facilities and teaching equipments of laboratories for home economics area were inferior, especially, for clothing and textiles part and housing part. Second, teachers recognized necessity to conduct experiment and practice highly. Food life part scored the highest, while housing part scored the lowest. Teachers who majored in home economics recognized more necessities of experiment and practice than teachers who didn't majored in home economics. Third, they recognized level of experiment and practice to be suitable to students, but 'maintenance and repair of housing' section was relatively less suitable than other sections. Fourth, 'making clothes and recycling' section was recognized to have the least suitability in quantities and hours of experiment and practice lesson, because of too much contents and lack of lesson hours. Fifth, teachers recognized that students were more interested in 'the basis of food preparation and practice' section, but they are less interested in 'maintenance and repair of housing' section. Sixth, teachers recognized that contents of experiment and practice were very useful to the real life. 'The basis of food preparation and practice' section was the most useful, while 'maintenance and repair of housing' section was the least useful. Seventh, experiment and practice lessons for food life part were put in practice very well, followed by the order of clothing and textiles part and housing part. Teachers who majored in home economics usually took more experiment and practice lessons than teachers who didn't major in home economics.

Because the probability education in the elementary statistics course is the starting part of the inferential statistics, it is hard to follow the lecture for undergraduate students. In this paper, we suggest the useful cases for the probability education in the elementary statistics course and give the corresponding R scripts.

Repetitive sequences such as SINE, LINE, and LTR elements form a major part of eukaryotic genomes. A literature search tool that summarizes the information contained within repeat elements would provide biologists in the field of genomics with a useful tool for analyzing genomic sequence features. We developed a java program designed to make literature access easier by using two search engines simultaneously. RepWeb is a web-based search system that provides a user friendly interface for searching the reference data and journals for information related to repeat elements by using the search engines, Google Scholar and PubMed, simultaneously. It provides an interface that displays the repeat element- related biological information, and includes useful functions such as the production of a repeat tree, clickable links to PubMed and Google Scholar, exporting, and sorting a field into date, author, journal and title.

Photopolymer films containing fluorescent anthracene polymer, polymethyleneanthracene (PMAn), were prepared with different concentrations of PMAn for holographic recording useful for security documents. The fluorescent photopolymer film showed enhanced fluorescent intensity due to the micro-separation which arose from grating formation and diffusion during photopolymerization. Experimental values of diffraction efficiency were well matched to the simulated values for photopolymers having different PMAn concentrations. Holography patterning was carried out using the fluorescent photopolymer under a photo-mask. A grating was confirmed using microscope techniques in the recorded area under the pattern. Importantly the recorded area showed enhanced fluorescence compared to the unrecorded part, allowing fluorescence patterns at micro scale along with the submicron grating pattern. The fluorescence pattern recorded on the photopolymer film provides additional readability of holographic reading and thus is useful for secure recording and reading of information.

In this paper real-time estimation methods for identifying the tire-road friction coefficient are presented. Taking advantage of the Magic Formula Tire Model, the similarity technique and the specific model for the vehicle dynamics, a reduced order observer/filtered-regressor-based method is proposed. The Proposed method is evaluated on simulations of a full-vehicle model with an eight state nonlinear vehicle/transmission model and nonlinear suspension model. It has been shown through simulations that it is possible to estimate the tire-road friction from measurements of engine rpm, transmission output speed and wheel speeds using the proposed identification method. The proposed method can be used as a useful option as a part of vehicle collision warning/avoidance systems and will be useful in the implementation of a warning algorithm since the tire-road friction can be estimated only using RPM sensors.

In the screening of those components with comparatively strong xanthine oxidase inhibition activities from Panax ginseng folium. trifolin. panasenoside. kaempferol and so far unconfirmed phenol whose chemical structure still without elucidation have been discovered as such components. Specific inhibitors of xanthine oxidase are thought to be therapeutically useful for the treatment of gout. Such opinion is considered to be useful to support the thought that ginseng folium is effective for the adjustment of gout. Although trifolin. panasenoside. and kaempferol are well known flavonoids. further studies on unidentified new phenols should be continued.

Objectives : This report is intended to suggest that lentigo can be removed using the cauterization. Methods : Handle of the needle, which is distal part to the tip and shaft, was heated with an alcohol lamp to cauterize the lentigo one by one to form a crust, and wet dressing was applied to the treatment sites by using Hwangryunhaedok-tang pharmacopuncture solution. Results : Ten days after the cauterization, the lentigo was cleared from the normal skin without adverse reactions. Conclusions : The cauterization is a useful technique for removing lentigo, but the conventional method is somewhat inconvenient, so a radiofrequency technique or a laser-based cauterization may be more useful Instead of the traditional cauterization.

In recent years, dramatic advances in information technology have motivated the construction industry to improve its productivity. Computer-based information technology includes Computer-Aided Design (CAD), Computer-Aided Engineering (CAE), Computer-Aided Manufacturing (CAM), Enterprise Resource Planning (ERP), Digital Mock-Up (DMU) and Product Data Management (PDM). Most construction industries are trying to apply these technologies for quality improvement, reduction of construction time and cost. PDM is very useful for managing data and process related to product design and manufacturing. PDM system has various functions such as drawing and engineering document management, product structure and structure modification management, part classification management, workflow management, and project management. In this paper, PDM system was applied to the design of steel-concrete composite girder bridge. To make a practical guidance for PDM implementation to bridge design, the procedure for its implementation was presented. Consequently, this paper could be useful to enhance the efficiency of bridge design.
