We teach students to explore geometric figures by its properties and establish relationships between some basic figures. The concept of parallel line play very im-portant roles in such geometry learning process. In this study, 1 investigate the con-cept of parallel line we teaching in elementary school. Students have wrong concept images for parallel line, which is the result of the elementary school mathematics text books, where only typical cases for parallel line Is presented and there is no method to find if two lines is parallel or not. Therefore, we should teach explicitly students to find if two lines is parallel or not. The depth study on it is needed to develope students' geometric thought level.

Bacillus subtilis 8 is highly efficient at degrading feather keratin. We observed integrated feather degradation over the course of 48 h in basic culture medium while studying the entire process with scanning electron microscopy. Large amounts of ammonia, sulfite, and $\text\tiny{L}$-cysteic acid were detected in the fermented liquid. In addition, four enzymes (gamma-glutamyltranspeptidase, peptidase T, serine protease, and cystathionine gamma-synthase) were identified that play an important role in this degradation pathway, all of which were verified with molecular cloning and prokaryotic expression. To the best of our knowledge, this report is the first to demonstrate that cystathionine gamma-synthase secreted by B. subtilis 8 is involved in the decomposition of feather keratin. This study provides new data characterizing the molecular mechanism of feather degradation by bacteria, as well as potential guidance for future industrial utilization of waste keratin.

As the world's population grows, how to maintain the food supply is becoming a bigger problem. Now and in the future, big data will play a major role in decision making in the agriculture industry. The challenge is how to obtain valuable information to help us make future decisions. Big data helps us to see history clearer, to obtain hidden values, and make the right decisions for the government and farmers. To contribute to solving this challenge, we developed the Agriculture Big Data Analysis System. The system consists of agricultural big data collection, big data analysis, and big data visualization. First, we collected structured data like price, climate, yield, etc., and unstructured data, such as news, blogs, TV programs, etc. Using the data that we collected, we implement prediction algorithms like ARIMA, Decision Tree, LDA, and LSTM to show the results in data visualizations.

The Ministry of Construction & Transportation revised the full text of 'The Act for Promoting Housing Construction' that concentrated to the quantitative supply of houses into 'Housing Act' in order to improve the quantity as well as quality of housing construction and management, such as housing welfare, management or improvement of previous houses, in October 2002. Accordingly, local authority need to play more critical roles in the area of multi-family housing management and remodeling. The desirable roles of local authority called for the need are like followings: 1. Local authority should provide professional knowledge for education, direction and consultation of multi-family housing management rather keeping the previous role to control, manage and regulate it. 2. The multi-family housing management should be changed from administration and punishment to incentive-centered institutions. 3. It is necessary to consider neglected people, such as occupants of rental apartment or of a small-sized multi-family housing, who have been excepted from the subject of obligatory management under the current law. 4. For harmonious and professional housing management, local authority need to support the establishment or special companies for housing management and to strengthen the audit on trust management companies. 5. It calls for the studies on management guideline of multi-family housing, standardization of management specifics, reasonable standard for special mending appropriation amount, etc. 6. They should lead the composition of a community by residents harmoniously and support the encouragement of community consciousness to live together.

The purpose of this study is to suggest the schemes to enhance information service functions by the utilization of CD-ROM in medical school libraries. The results of the study are summarized as follows : 1. The selection and evaluation of CD-ROM database are necessary steps in the planning of a CD-ROM. Before the CD-ROM is selected, therefore, medical libraries must make a practical evaluation criteria in important order of information services environment, characteristics of hardware/software, service requirements, price and cost, etc. 2. If possible, CD-ROM MEDLINE must be suited for the information services environment. 3. In case of the popular core journals, full-text CD-ROM should be gradually purchased. 4. In order to reduce the time required from search of bibliographic informations to receipt of original articles, CD-NET system and library holding administration program must be built up and developed. And channel of information search and order/receipt of original article should be varied. 5. Search education program for medical librarians and users should be enforced, and librarians must play an important role in CD-ROM retrieval consultant and intermediator.

The case study describes kindergarten children's reading stances and responses with relation to those of their mothers'. Rosenbaltt's theory (1978) of aesthetic and efferent stances in used to characterize the relationship between the reader and the text. mother's reading stances are examined by observing each case study child's reading experience with his/her mother at home. In most cases differences in some children's preferred stances seemed to reflect differences in their mothers' stances. As a result, children took a different type of stance from the teacher's efferent stance and were perceived by the teacher to be slower with regard to literacy development, even though they had formed their own reading worlds. Interestingly enough, children with an aesthetic reading stance were welcomed among their peers during free play time. In contrast, children who took a stance congruent with the teacher's efferent stnace were perceived by the teacher to be on the right track with regard to literacy development, although their reading worlds seened to be limited. Interestingly, the children with efferent reading stances were not engaged in collaborative meaning negotiation processes with peers. The case study children with mothers who did not take an extreme type of stance, I.e., neither a very efferent nor a very aesthetic stance, seemed to choose a type of stance depending on a context.

Purpose: The purpose of this study was to describe what critical care nurses perceived about life-sustaining treatment at end of life. Methods: A qualitative content analysis method was utilized. The unit of analysis was interview text obtained from fifty critical care nurses of a general hospital. Results: Seven categories in two content areas were abstracted. In the negative perception area, the following five categories were abstracted: patients' suffering, dying with damaged dignity, patients' isolation from family members, regret about choosing life-sustaining treatment, and family members' burden. In the positive perception area, the following two categories were abstracted: willingness to sustain life and duty as family members. Conclusions: Nurses have better competencies pertaining to understanding patients' responses and suffering than any other health care professions do. Nurses should play an important role in advocating for patients and their family in the process of end-of-life care decision making.

This paper aims to present how to design and implement a multimedia tutorial system for the self-learning French language using Director with additional tools. To implement a multimedia tutorial system we need to design several steps. First, we should choose the level of the users and design tutorial. Second, we should prepare all materials such as sounds, graphics, text and video. Finally, we should implement the selected elements and control the educational software. Due to the nature of the paper, it must emphasize French basic conversation to make environment that be used in each scene and the scene of the context dialog. In view of the fact that the fitness of each content utilization field of multimedia authoring tool is high, it is possible as part of the system sizing process of the manufacturing process, to impart its meaning. This learning-contents are composed of 10 units each situation, and we anticipate there are the several effects of this system on basic French students. This system helps lecturer get French students interested in lessons, and enables learner to learn French of the role of iterative practice by linking image and sound. Also this system helps learners to prepare and review French studying after a lesson and allows leaners to maximize their efficiency. The future of this work is to implement this system on the app.
