Instead of a highly toxic CdSe and ZnScore-shell,InP/ZnSecore-shell quantum dots [1,2] were investigated as an active material for quantum dot light emitting diode (QD-LED). In this paper, aquantum dot light-emitting diode (QDLED), consisting of a InP/ZnS core-shell type materials, with the device structure of glass/indium-tin-oxide (ITO)/PEDOT:PSS/Poly-TPD/InP-ZnS core-shell quantum dot/Cesium carbonate(CsCO3)/Al was fabricated through a simple spin coating technique. The resulting InP/ZnS core-shell QDs, emitting near blue green wavelength, were more efficient than the above CdSe QDs, and their luminescent properties were comparable to those of CdSe QDs.Thebrightness ofInP/ZnS QDLED was maximumof 179cd/m2.

Multi-color organic electroluminescent (EL) displays have already been commercialized, and the simple extensions of present technologies on organic EL can not be a target for basic research anymore. Future prospect of research on organic electroluminescent devices are described from the view point of possible future break-through. Three aspects, perspective for further increase of device efficiencies, possibility of simplified device structures and possible use of thick organic layers, are discussed.

This research presents an analysis of some of the occupations associated with Korea‘s national strategic industries. Therefore, the objectives of this paper can be summarized as follows: By classifying existing occupations and identifying potential future ones, this paper will strive to present a systematic analysis of environmental related occupations. In order to achieve the objectives of this research, related literature was examined, a Delphi Survey was conducted. In order to select potential future occupations, this research used a qualitative method that involved interviews with specialists. More specifically, a Delphi Survey was used to collect the specialists' opinions. The potential occupations were selected using a three-prong procedure involving an analysis of related literature and materials, a Delphi Survey, as well the holding of conferences with specialists and visits to those in the actual field. Through this process, 33 different potential future occupations were selected.

The rapid growth of smart devices demands an enhanced throughput for network connection sustainability during mobility. However, traditional wireless network architecture suffers from mobility management issues. In order to resolve the traditional mobility management issues, we propose a novel architecture for future wireless access network based on software-defined network (SDN) by using the advantage of network function virtualization (NFV). In this paper, network selection approach (NSA) has been introduced for mobility management that comprises of acquiring the information of the underlying networking devices through the OpenFlow controller, percepts the current network behavior and later the selection of an appropriate action or network. Furthermore, mobility-related scenarios and use cases to analyze the implementation aspects of the proposed architecture are provided. The simulation results confirm that the proposed scenarios have obtained a seamless mobility with enhanced throughput at minimum packet loss as compared to the existing IEEE 802.11 wireless network.

With rapid development of various information and communication technologies, to forecast future became important for coping with new environment. Experts in each field of study are forecasting future society, and considerable life scenarios are derived in the process. Life scenarios help people to approach and understand future circumstances easily. Therefore, to study future housing with life scenarios as materials will be helpful to establish the direction to the development of current housing. The purpose of this research is to examine what characterizes the housing functions and life behaviors of future house and what is changing from the housing functions and life behaviors of past and present. Content analysis was used as research method. The subject was 10 future forecasting books which reflects daily life in the house, and 1 episode relating residential space as 1 analysis unit, the total of 213 episodes were analyzed as materials. As a result, most of the life behaviors in the house are expected to be performed by robots instead of humans in the future. On the other hand, partial life behaviors are already being performed mostly by computer system, and another partial life behaviors show that the role-performance of them are not being totally by robots but partially with human.

The future is complex and unpredictable. In particular, it is unlikely to occur, but once it occurs, no one knows how it will affect our society if X-event, which has a tremendous impact, is created. This study was conducted only in the climate field to offset the ripple effect of this X-event, and was conducted through in-depth interviews with experts from the Korea Army Research Center for Future & Innovation and the Army College. As a result, it was possible to explore what factors would trigger X-event from their discourse and what X-event would be newly created by spreading them to other fields. Starting with this study, if we accumulate the discourse of experts in various fields such as population, science and technology, as well as climate, and other fields other than the Army, we can predict X-event and offset the threats that may arise.

Objectives of this study are to analyze the previous research perfomed in the Bus Information System (BIS) area and to suggest future research directions. This is a very meaningful and important work. To accomplish this, this study (1) summarizes the concepts of BIS, (2) establishes a research framework to be used to analyze the previous studies in the area, and (3) identifies and suggest trends and future directions of the BIS research. This study has identified total of 68 article (22 foreign and 46 domestic) using 'Google Scholoar' search engine. Major research results include (1) since non-empirical research is dominant, more explanatory empirical research is needed in the future, (2) research that provides consistent and comprehensive measures for BIS related constructs (e.g., BIS quality) is needed, and (3) impacts on the stakeholders of BIS not reflected in the current research (e.g., bus drivers, administrative agencies) should be analyzed in the future research.

This experiment was carried out to investigate the effect of several organic compost on the growth and root yield of Scutellaria baicalensis G. with organic cultivation from 2008 to 2009. Four organic compost were used ; Rice bran compost (RC : 1.1-3.6-1.4), Wheat bran compost (WC: 1.1-3.4-1.4), Hangawi compost (HC : 3.7-4.0-1.0), Cheonnyeonjigi compost (CC : 12.4-3.4-5.4) and Fermented chicken droppings compost (FC : 2.9-6.1-3.2). Organic matter, available phosphate and $K_2O$ of soil increased in all plots with the addition of organic compost, specifically in HC, CC and FC application. Treatment of HC, CC and FC application increased emergence rate and improved the growth characters of shoot, root parts of plants compared to those of RC application. Subterranean part yields by different organic compost was high 149~156 kg per 10a as by growth increment of dried root yield. length of main root and diameter of main root. respectively, 17.4~18.4 cm, 12.65~12.94 mm from HC, CC and FC application. There were significantly positive correlation between the growth characters of shoot, root parts of plants, dry root yield in Scutellaria baicalensis G. grown under organic compost application.
