The present study examined the differences of system and problems of descriptive assessment at the national, district level, and school's levels between Korea and U.S.A. (focused on NCTM perspective). As results, both Korea and U.S.A. showed that their goals for descriptive assessment at the national level pointed out the importance of assessment of process rather than result. In addition, States of U.S.A. demonstrated concrete rubrics and examples to help many school teachers to use easily, while many Districts of Education in Korea presented implementation rate in school in order to give a official direction to teachers.

The purpose of this study is to understand two geography student teachers' experience of practical knowledge on the geography classroom organization during their student teaching. I carried out a qualitative case study on the geography classroom organization and its practice. Data was gathered through participant observation and in-deep interview. The results are as follows: 1) I present portraits two pre-service geography teachers' lives, which represent typical case of intrinsic deep motivation and spontaneous interest in subject matter. 2) Their classroom are organized $9{\sim}14$ segment, its segment organizations in introduction close steps and main lesson step behave differently. The segment activities in close step behave most irregularly. 3) In the reflection rubric, the level of their reflection is middle, mostly concentrated on 'technical' or 'dialogue' level. On the basis of these findings, it can be concluded that a different way of understanding the relationship between knowing to teach and knowing about teaching is necessary.

Menu is the most common interaction tool to select and execute a specific menu item from multiple menu options. With the very rapid increasing amount of information, various new menu designs have been developed. In this research, the pull-down menu, fisheye menu and grid menu were tested to compare the performance time, error rate, simplicity, usefulness, user friendliness, and overall user preference of each menu type. The grid menu was more efficient in selection speed than the pull-down and fisheye menus when the number of menu-items was 50 and 100. The time needed to choose a menu-item with a grid menu was less affected by the size of menu. The pull-down and the grid menus were considered to be more satisfactory, simple, user friendly, and useful than the fisheye menu. 42.3 percent of subjects indicated that the grid menu was their preferred selection tool among the menus. The grid menu is an efficient and robust alternative menu choice for small and middle size menu list. Further study is required to examine the possibility of grid menu on mobile devices.

With the increasing popularity of multi-core processors, they have been adopted even in embedded systems. Under this circumstance many multimedia applications can be parallelized on multi-core platforms because they usually require heavy computations and extensive memory accesses. This paper proposes an efficient thread-level parallel implementation for color space conversion on multi-core CPU. Thread-level parallelism has been becoming very useful parallel processing paradigm especially on shared memory computing systems. In this work, it is exploited by allocating different input pixels to each thread for concurrent loop executions. For the performance evaluation, this paper evaluate the performace improvements for color conversion on multi-core processors based on the processing speed comparison between its serial implementation and parallel ones. The results shows that thread-level parallel implementations show the overall similar ratios of performance improvements regardless of different multi-cores.

The purpose of this study is to find out how much psychosocial factors affecting the intention to use mental health services and the characteristics of respondents in college students. Specifically, the influence of the level of knowledge about mental health, subjective norms, attitudes for seeking help, and social psychological stress levels on the respondents'intention to seek help is examined. As a result of the study, it was found that the subjective norms, social and psychological stress levels, and mental health students'intention to use mental health services were influenced by factors. It was found that subjective norms, psychosocial stress level, and attitude toward using mental health service were factors that influence the intention to use mental health service. The influence of these factors on help seeking intention was in the order of psychosocial stress level, help seeking attitude, and subjective norm. The study provided implications that were helpful in message development when executing mental health promotion and awareness campaigns by identifying predictive factors of the intention to use mental health services of college students.

Current science education aims to guide students as future responsible citizens to make informed decisions on socioscientific issues (SSI). In the authors' previous study, it was found that conceptions of nature of technology (NOT) were explicitly represented in various contexts of SSI with differentiated levels of understanding, and cases of the informed NOT understanding included the key features of well-reasoned SSI decision-making. Therefore, enhancing NOT understanding could be one of the elements to leverage students' informed SSI decision-making. In this study, we developed a rubric to assess NOT understanding in the context of SSI and applied it to evaluate the impact of SSI instruction. Participants were 58 college students who took an SSI course for 6 weeks. Before and after the SSI course, they were asked to write decision-making essays on the Golden Rice issue (a type of genetically modified food). As a result of analyzing the pre- and post decision-making essay using the rubric, it was found that NOT understanding was improved after the SSI course; in addition, the salient patterns of NOT changes were analyzed in detail in order to gauge the influence of the SSI classes. Implications for science education were discussed.

Objectives : This study examined the selective deficits of executive function in patients with mild traumatic brain injury that in normal range of general intelligence level and aimed to analysis of the correlation between K-WAIS result and executive function. Methods : 59 subjects were included in this study, who were diagnosed as mild traumatic brain injury(MTBI) and they have visited in neuropsychiatric department of Wonkwang University Hospital during from March, 2005 to September, 2010. For measurement of general intelligence quotient, the Korean-Wechsler Adults Intelligence Scale(K-WAIS) was administered and for measurement of executive intelligence quotient(EIQ), Executive Intelligence Test(EXIT) was administered. Results : Of patients, 50.8% included at abnormal EIQ group. The patients of abnormal EIQ showed poorer full scale IQ(FIQ), performance IQ(PIQ) and in subscale that picture arrangement, digit symbol, digit span, block design, object assembly and comprehension were significantly different. In terms of relationships between K-WAIS and EIQ, FIQ and PIQ have positive correlation with EIQ. And in subscale, picture arrangement, digit symbol, digit span, block design, object assembly and comprehension show positive correlation with EIQ. Conclusion : This study suggest that MTBI patients with have normal range of general intelligence level may have deficit of executive function is common. The decline of FIQ, PIQ and some subscales of K-WAIS may suggest executive dysfunction in MTBI patients.

It is necessary to look at the essence of STEAM education from the viewpoint of the teacher who is the subject of education execution. We carry out questionnaires and telephone interviews for the purpose, definition, change, etc. of STEAM education from eight elementary, middle, and high teachers who are rich in policy and field application experience. As a result of the analysis, the purpose of the STEAM education that the specialists mentioned includes the active participation of the students. Most experts pointed out that the definition of STEAM education is ambiguous. So, it is necessary to express a clear goal of STEAM education. The category and level meaning "fields" from "a convergence of two or more fields" are not indicative definitions, but can be different depending on the situation, considering the context of activities and the level of students. The perception of the experts on framework may be a guide for STEAM education and stumbling block. It is necessary for "Context" to shift away from the emphasis on the real life connection and to the emphasis on the interest of the student and the guidance of the class. "Creative design" must be based on trial and error in the process of solving problems. "Emotional touch" needs to correct elements that cannot be observed, evaluated, and applied to lessons that are elements of emotional experience. As for the expansion of STEAM education, most expert teachers have recognized that STEAM education is becoming increasingly stable and that policy change has continued to slow the pace of stabilization.

As interest in advanced countries regarding the convergence technology development increases, a methodology for identifying the core convergence technology that has a large spill-over effect on the technology and industry is required for the nation's competitiveness enhancement in the convergence technology field. Based on patent citation network analysis using 1,124 USPTO patents in the ICT convergence technology field of the smart factory, this study examined the proposed heterogeneous technology convergence index as a tool for measuring the convergence characteristics of the spillovers compared to other indexes (i.e. other sector ratio index and homogeneous technology convergence index). The proposed heterogeneous technology convergence index was used to investigate core technology sectors among ICT technology sectors of smart factory identified by government ministries. Results found 6 core ICT convergence technology sectors including the manufacturing execution analysis application sector. Also, this study conducted blockmodeling analysis using the IPC codes of patents in the manufacturing execution analysis application sector, and identified that the blocks representing the electronic communication and electric digital data processing technology sectors (Block 3 & 4) are related technology sectors which can be converged with core technology. Based on the findings, the implications for the convergence technology development planning of the smart factory field are discussed.
