The commercialization of an active matrix e-reader display using E Ink microencapsulated electrophoretic (MEP) ink marked a big step towards comfortable reading over an extended period of time in an electronic book, as the high resolution display, jointly realized by Philips, E Ink and Toppan, has a true paper-like look and feel. Alternative electrophoretic material systems are being developed by SiPix and Bridgestone and progress has been made in the past two years. In this paper, electrophoretic material systems are briefly reviewed, after which the perspectives and challenges of electrophoretic displays are addressed and methods for generating gray tones are presented and discussed.

The main theme of this paper is to evaluate the relevance of Educational Facilities in terms of university change in near future. The paper reviewed the changing process of higher education and its role in Korean society briefly, proposed the developmental directions of higher education in future in several perspectives, and introduced educational reform plan in the field of higher education proposed on May 30, 1995 by advisory group to the president. In this context, the irrelevance of university and college education facilities was pointed out, and proposed some new and modernizing guide lines of educational facilities such as flexibility, openness, corelationships and consortium among related institutes, optimization of related laws and rules, exemption from the direct ruling and control of government. This paper also suggested some ideas of facilitating educational facilities in accordance with the future change trends of university and college education.

One common roadblock to innovation is the inability to define the problem that needs to be solved. Main contributors to this situation are the complexity of real field and the psychological inertia. 9-Windows can help break the complexity and the psychological inertia. In this article, we attempt to propose how to link resources to space and time framework through 9-Windows. Also, we propose how to use the 9-Windows to find multiple perspectives and explore solutions to a problem. This research is expected to be a vehicle to make an effective use of 9-Windows along with TRIZ, SIT, CT, FMEA and QFD.

Formula for the area of a trapezoid is an educational material that can handle algebraic and geometric perspectives simultaneously. In this note, we will make up the expression equivalent algebraically to the formula for the area of a trapezoid, and deal with the conversion of a geometric point of view, in algebraic terms of translating and interpreting the expression geometrically. As a result, the geometric conversion model, the first algebraic model, the second algebraic model are obtained. Therefore, this problem is a good material to understand the advantages and disadvantages of the algebraic and geometric perspectives and to improve the mathematical insight through complementary activity. In addition, these activities can be used as material for enrichment and gifted education, because it helps cultivate a rich perspective on diverse and creative thinking and mathematical concepts.

We propose an alternative procedure to select penalty parameter in $L_1$ penalized robust regression. This procedure is based on marginalization of prior distribution over the penalty parameter. Thus, resulting objective function does not include the penalty parameter due to marginalizing it out. In addition, its estimating algorithm automatically chooses a penalty parameter using the previous estimate of regression coefficients. The proposed approach bypasses cross validation as well as saves computing time. Variable-wise penalization also performs best in prediction and variable selection perspectives. Numerical studies using simulation data demonstrate the performance of our proposals. The proposed methods are applied to Boston housing data. Through simulation study and real data application we demonstrate that our proposals are competitive to or much better than cross-validation in prediction, variable selection, and computing time perspectives.

This study presents the rationale for the development of the Comparison Level Scale(CLS) and the Comparison Level for Alternatives Scale(CLAS). Data from 130 married women who live in the U.S.A. suggest that the CLS and the CLAS are internally consistent and unidimensional. The CLS and the CLAS are based on exchange theory perspectives, particularly, Thibaut and Kelley's theory, on evaluating an individual's comparative processes. The scales provide explanatory as well as descriptive power concerning evaluating an intimate relationship.

The Outsourcing Industry has grown swift pace and evolved over time, and the Global IT Outsourcing market has shown signs of a steady growth. In the Korean company, however, IT Outsourcing is not active as that of the advanced countries and there is lack of literature to understand the characterristics of IT Outsourcing in the Korean company. This paper, therefore, analyze the outcomes surveying 65 compaanies in Korea to investigate how IT Outsourcing risk factors affects IT Outsourcing intention. Based on our literature reviews bassed on number of key articles, journals, and the focus group interviews, IT Outsourcing risk factors are proposed into four different domains: Transaction, Client, Vendor, Environment perspectives. It found that one factor(Vendor perspectives) is closely related to the IT Outsourcing intention of the Korean company. Finally, this paper analyzed the pros and cons of IT Outrcing offers a guide to the risk factors.

This research aims at exploring what Korean teachers of English need for their effective professional development, particularly from the perspectives of peer trainers who are school teachers as well as teacher trainers. The research is based on an assumption that despite the critical roles of peer trainers in the changing process of English education, very little attention has been paid to listening to their voices. Having an awareness of the meaningfulness of their voices in teacher education, the researcher collected and analyzed the data, employing a questionnaire responded by 32 peer trainers and in-depth group interview with 6 peer trainers who responded the questionnaire. The research findings suggest that the majority of peer trainers believe that the priority should be put on teaching practice rather than language competence for Korean English language teacher development. It has been found that they believe that teacher learning within the workplace with some support from outside experts is the most effective way of making classroom change possible and keeping teachers' professional development sustainable. Finally, the research suggests school-based professional development as an alternative strategy to satisfy their needs on effective and sustainable professional development.

This study examined the effects of a geographic experiential activity program on the ability to represent and to read maps(directions, perspectives, and symbols). The subjects were 44 5-year-old kindergarten children assigned to an experimental or a control group, with 22 children in each group. The geographic experiential activity program was developed and applied to the experimental group for 4 weeks. Results indicated that the experimental group was higher in reading and representing maps than the control group. Through the geographic experiential activity program, children came to be concerned about their living space, to be able to read and comprehend a simple map, and to represent a basic map with the use of directions, perspectives, and symbols.

Purpose: This study was conducted to explore the perspectives of gender and role in the family for nurses' work-family balance. Method: Data were collected through in-depth interviews with 14 married nurses having children, who were selected through convenience sampling and purposive sampling from November 1, 2011 to January 20, 2012. The data were analyzed using qualitative thematic analysis. Results: The common themes resulted from data analysis included following traditional gender roles, giving up any expectation of spouse's role, coordinating the division of family roles, and refusing to stick to gender roles. The age of nurse, family background of husband, and social-economic contexts were essential to explain the couple dynamics. Conclusions: Nurses who received private family support were stably leading a work-family balance, yet unable to change the gender structure of spouse for the work-family balance. On the other hand, young nurses who were unable to get any support, had a tendency of cooperating with their spouses and adopting more negotiable and pragmatic approach to work-family balance.
