Countries that considered importance of the quality management of higher education are strengthening through various systems and methods. Field of computer science also, they have constantly made efforts, such as constituting standards of curriculum for the management of the quality of higher education. If we know the priorities of the knowledge area mentioned in the standard of curriculum of computer science, we can give implications to the composition of the content system. Therefore, we derive the ranking based on base on CS2013 the lesson time number of Tier 1, Tier 2, Elective, and detail areas for content elements. As a result, the knowledge area with the highest priority was Software Development Fundamentals. The knowledge area is recommended as a beginner course in CS2013 because it is a basic element. The priorities of these areas may provide implications for future elementary and secondary informatics curriculum, higher liberal arts informatics curriculum, Informatics curriculum of teacher training agency.

Although the e-learning system is being introduced in elementary and secondary education, incorporating it into the regular curriculum is difficult. Other problems include the lack of sessions and connection to regular courses in realistically applying project-based learning in the regular school curriculum. Therefore. this study established, applied, and analyzed the blended learning strategy to resolve such issues. Specifically, a theoretical investigation on the concept of blended learning and IT-oriented, project-based learning was conducted. The theme for learning based on integrated courses was also selected, and the 5-stage project-based teaching and learning strategy, concretized. The concretization strategy involved discussion, role division, and alternative evaluation strategy. The class progressed in formats of on-class online, on-class offline and off-class online. As a result, students experienced inconvenience since the project only lasted for a short period of time. Nonetheless, they responded positively to the effect of project-based learning in general. This study was able to suggest the possibility of applying e learning in regular school curriculum and propose the direction for digital and learner oriented teaching.

We study on the Connected Mathematics Project(CMP), one of the American mathematics education reform projects which have been promoted since the 1990s, so that we can provide some suggestions for the recent research of developing the 2009 Korean Mathematics Curriculum. In this paper, we examine the background of the CMP, the controversies over the textbooks [CMP1 textbooks] developed by CMP[CMP1] implemented from 1991 till 1996, and the curriculum of the CMP[CMP2] revised from CMP1 and carried from 2000 till 2006. Through the literature study, we can see that the CMP2 curriculum has reflected some of those controversies of the CMP1 textbooks by introducing procedures for students' acquiring basic skills, reducing the number of lessons and the contents supposed to be learned in each lesson, putting more stress on algebra and adding data analysis contents more.

This study aims to identify parents' recognition of school-enterprise convergence by type of disability. To this end, it analyzes 150 parents with children attending special school in region D, K, and S. As a result, first, parents preferred their children's vocational ability development, employment rate improvement, and manufacturing and supplying method of goods requested by industrial bodies in the community the most and hoped to complete educational courses for the professional education of a job that they wanted to learn and learn the basic ability education for the job. Second, they preferred participation in practical hours and after-school activities and hoped all 2nd and 3rd high school graders to be selected if they wanted, and as compensation for them, wanted appropriate adjustment of class hours or tasks. This suggests that active participation in classes and selection of various types of business seem to be necessary.

On an offshore plant topside, various types of offshore facilities for processing energy resources, such as oil and gas, and equipment and outfitting for connecting these facilities are installed in a limited space. An offshore plant superstructure is composed of numerous supporting rack structures and reinforcements for securing and supporting offshore installations and the related equipment. This paper describes the development of design support software to support this superstructure design efficiently. The developed design support software, which was based on AVEVA Marine's PML(Programmable Macro Language), supports the parametric method for superstructure design. A method of batch 3D modeling from 2D drawings for supporting rack structure produced in the basic and detailed design was also developed using AutoLisp. In addition, through the application example of superstructure module design, the design support software introduced in this paper can be expected to reduce the design time by more than 90% compared to the use of only basic functions of AVEVA PDMS.

This study was carried out to ascertain the flowering and boiling habits in conditions of vinyl mulched cultivation. The effects of vinyl mulching cultivation in cotton was early flowering. The flowering period was no more than 26 days and shedding of flower bud was lower. The total boll setting rate to flower number was about 38%. The number of flowering plants was rapidly increased until Aug. 8, then later was decreased, the period of the highest flowering occured was for 5 days from Aug. 6 to Aug. 10. Boll setting was increased that the flowers opened before July 30, then the later flowers was tended to decrease belling in spite of the increased flowering. However flower bud shedding had a tendency to decrease after the highest boiling period. The effect of weather, max. temperature and hours of sunshine on flowering days were highly positive significant correlation. Minimum temperatures, high air humidity and amount of rainfall had a negative significant correlation. The demanded days to flowering on the same internode in each fruiting branches was taken average 1.2 days, these days among the fruiting branches of the same internode was 3.6 days.

The objectives of this research are to investigate the mechanism of coagulation affecting UF and find out the optimum conditions of the combined of coagulation with UF membrane filtration for NOM removal. During the mixing period, substantial changes in particle size distribution occurred under rapid and slow mixing condition due to the simultaneous formation of microflocs and NOM precipitates. Therefore, combined pretreatment using coagulation (both rapid mixing and slow mixing) improved dissolved removal efficiency. Also, for combined coagulation to membrane process, flux reduction rate showed lower than only UF process. The rate of flux decline for the hydrophobic membrane was considerably greater than for the hydrophilic membrane. Applying coagulation process before membrane filtration showed not only reducing membrane fouling, but also improving the removal of dissolved organic materials that might otherwise not be removed by the membrane.

A weld scallop is a small quadrant or half circle type hole installed in the weld line cross area for easy welding operation. Many types of T-bars with a scallop can be welded in a block assembly stage in shipbuilding. The difficulties arise from the fact that scallops are to be filled by build-up welding after welding of the cross line is complete. In this study, a non-scallop block joint welding method was developed using special type CBM (ceramic backing material). The wedge shaped CBM was devised to insert a CBM into just the V groove of weld line cross area without weld scallop. A saw-toothed shape was adopted for easy cutting of the unnecessary part in the CBM fitting process. The applicability of the developed method was verified through welding experiments based on the yard welding conditions.

The purpose of this study is proposing implications toward liberal arts Informatics education at universities in Korea by analyzing Japan's liberal arts Informatics curriculum standards. For this aim, the changes of the two standards have been compared focusing on a variety of researches related to J07-GE and J17-GE. In order to examine the scope and degree of Informatics knowledge reflecting J17-GE, which is a revised version, the analysis has been conducted through the relationship between curriculum standards regarding CS. As a result of the analysis, it has been identified that principles and knowledge of informatics can nurture competency of university students as universal liberal arts through J07-GE and J17-GE based on Computational thinking viewpoint and Japanese Informatics studies definition. Thus, when it comes to developing curriculum, discussion of not only knowledge system but also number of classes and methods have to be taken into account. This study is meaningful in the sense that it proposed directions for advancing university liberal arts Informatics education and developing liberal arts Informatics curriculum standards.

The 21st century computer education is very important for the future generations in the knowledge and information society. Therefore, developed countries that are the US, UK, and Germany, it is very important to find out how the computer education. In the US, the NETS and ACM K12 curriculum are investigated, In the UK and Germany national level computer curriculums are looked out. USA, UK, and Germany's curriculum includes computer science, information technology, digital literacy, and computer curriculum is independent, at least in the elementary schools computer education can be seen that more than 17 hours. After the revised national curriculum at 2015 is amended in korea. compared to the developed countries to derive the problems of the Korean revised national curriculum 2015. The revised 2015 Korean elementary school computer education, has no identity because it is not operated as an independent subject. Software will include education only. A very limited time of 17 hours may be a problem.
