  • We developed a new PDP gray scale implementation method on the basis of the quantized memory addressing(QMA) principle. We defined three wall charge states; 'fully-on', 'off', and 'half-on', by controlling the width of address pulses. With these three wall charge state, we were able to express 255 level gray scale with only 7 sub-fields. Furthermore, in contrast to the conventional driving methods, the sub-field combinations for any two adjacent gray levels differ by only 1 sub-field, at worst, and therefore, eliminate the dynamic false contours. Since this method use 7 sub-field, the sustain discharge Period is increased by more than $70\%$ compared to the 12 sub-field method which reduces the dynamic false contours.

  • This paper proposes an algorithm of address analysis for the next-generation networks. That is, we present integrated address analysis of the Numbering Plans of public telecommunication networks such as those of the ATM network. The purpose of implementing software for integrated address analysis is to actively and flexibly cope with a large change of information while operating the system and the network. By designing and implementing a database structure and an address analysis algorithm, interworking is possible among part (local) networks that each have a different Addressing Plan within an integrated network. Proposed relational model database structure has effect that do to manage address information of complicated network efficiently. Also, apply in real environment and proved excellency through interworking test to verify mechanism that propose.

  • Packet transmission and independent addressing in the mobile environments are very similar to the ones in the multicasting environment. So, in this paper, we propose a new scheme about how to manage the multicasting group and to set the communication path in the mobile environment by applying two-level addressing mode, which is similar to mobile If, for location-independent address setting. And we propose the smooth handoff scheme that minimizes the handoff delay for mobile multimedia services. To check the performance of our proposed scheme, we modified the NS-2 network simulator and as a result, we showed that our proposed scheme is better than other techniques in terms of handoff delay and transmitted packets' throughput.

  • The voltage controlled ramp waveform(VCR) has recently been used in the reset period prior to addressing for plasma display. However, in this paper, the current controlled ramp waveform(CCR) which may prevent the oscillation of gap voltage cause current growth and decrease the background luminance has been suggested. As a result, in case of CCR method, the contrast ratio was about 14% increased compared with VCR method, whereas the addressing and sustainin discharge characteristics of CCR method were same with those of VCR method.

  • This study explored the accumulated personal practical knowledge of six experienced science teachers in teaching SSI. The guiding research questions were: 1) how did they develop their understanding of SSI and their goals for teaching SSI over many years, and 2) what are the practical issues that the teachers have experienced while addressing SSI in science classrooms. The data source included individual interviews with six science teachers. Each interview lasted 50-70 minutes long and was audio-taped. Data was analyzed based on the methods suggested by Miles and Huberman (1994). Results indicated that, although their motivations for teaching SSI were personal and different, two major categories emerged. One group of teachers was mainly motivated by SSI itself, and the other group was motivated by the teaching aspects that SSI brings. The SSI-oriented group was very sensitive to SSI as it occurs in contemporary society. The teaching-oriented group paid more attention to the educational benefits that addressing SSI could bring to students. Their motivations for teaching SSI influenced how they set up their purposes for teaching, and their purposes for teaching guided them to use appropriate teaching strategies to make their SSI teaching more effective. All of their practical concerns were also connected to their basic motivations for teaching SSI.

  • If the ambient temperature rises in AC PDP, some of the discharged cells arc turned off because of the addressing failure. Particularly, the addressing failure at the last scan line is more serious than at the first scan line. The failure is accompanied with delay of the address discharge and reduction of total charge involved. In order to compensate this kind of misfiling, the progressively increasing address voltage waveform is used instead of constant one. In this method, we found that the total charge and address time at the last scan line are similar to those of the first line. As a result, we can have stable discharge without misfiring even at the high ambient temperature.

  • This paper propose the issue of connecting nested NEMO (Network Nobility) networks to global IPv6 networks, while supporting IPv6 mobility. Specifically, we consider a self-addressing including topology information IPv6-enabled NEMO infrastructure. The proposed self-organization addressing protocol automatically organized mobile routers into free architecture and configuration their global IPv6 addresses. BU(binding update) to MR own HA and internal rouging, hosed on longest prefix matching and soft state routing cache, are specially designed for IPv6-based NEMO. In conclusion, numeric analysis ore conducted to show more efficiency of the proposed routing protocols than other RO (Route Optimization) approaches.

  • Purpose: The aim of this study was to investigate the characteristics of intervention programs for internet/smartphone addiction among adolescents through an integrative literature review. Methods: We searched MEDLINE(PubMed), CINAHL, Embase, DBpia, RISS, and KISS using a combination of "Internet or $phone^*$," "$addicti^*$," "adolescent," and "intervention or program or therapy." The searched studies were reviewed according to the criteria and an integrative literature review was conducted on the 14 selected papers published from January 1, 2013 to November 14, 2017. Results: Through the integrative review and analysis, a total of four attributes of interventions and their effects were derived. First, the number of group-focused interventions was significantly higher than that of individual-focused ones. Second, the interventions addressed various aspects of adolescents' problems while considering the complex nature of addiction problems. Third, there was a bias for region and sexual ratio. Lastly, most studies were actively conducted in community-based counseling or psychology settings. Conclusion: It is necessary to find more effective methods for addressing internet/smartphone addiction among adolescents through multidisciplinary approaches, including the consideration of various cultural and gender characteristics. This study provides a basis for developing future programs addressing addiction problems among adolescents.

  • The United States Department of Energy (US DOE) is conducting research and development (R&D) activities under the Used Fuel Disposition Campaign (UFDC) to support storage, transportation, and disposal of used nuclear fuel (UNF) and wastes generated by existing and future nuclear fuel cycles. R&D activities are ongoing at nine national laboratories, and are divided into storage, transportation and disposal. Storage R&D focuses on closing technical gaps related to extended storage of UNF. Transportation R&D focuses on ensuring transportability of UNF following extended storage, and addressing data gaps regarding nuclear fuel integrity, retrievability, and demonstration of subcriticality. Disposal R&D focuses on identifying geologic disposal options and addressing technical challenges for generic disposal concepts in mined repositories in salt, clay/shale, and granitic rocks, and deep borehole disposal. UFDC R&D goals include increasing confidence in the robustness of generic disposal concepts, reducing generic sources of uncertainty that may impact the viability of disposal concepts, and developing science and engineering tools to support the selection, characterization, and licensing of a repository. The US DOE has also initiated activities in the Nuclear Fuel Storage and Transportation (NFST) Planning Project to facilitate the development of an interim storage facility and to support transportation infrastructure in the near term.
