Personalized reminder systems have to identify the user's current needs dynamically and proactively based on the user's current context. However, need identification methodologies and their feasible architectures for personalized reminder systems have been so far rare. Hence, this paper aims to propose a proactive need awaring mechanism by applying agent, semantic web technologies and RFID-based context subsystem for a personalized reminder system which is one of the supporting systems for a robust ubiquitous service support environment. RescorlaWagner model is adopted as an underlying need awaring theory. We have created a prototype system called NAMA(Need Aware Multi-Agent)-RFID, to demonstrate the feasibility of the methodology and of the mobile settings framework that we propose in this paper. NAMA considers the context, user profile with preferences, and information about currently available services, to discover the user's current needs and then link the user to a set of services, which are implemented as web services. Moreover, to test if the proposed system works in terms of scalability, a simulation was performed and the results are described.

e-Health system is the use of information and communication technologies to provide health care information and services to stakeholders. It pursues an improvement of service quality of health care, increases of accessability of information, reduction of medical cos and enforcement of competitiveness in health care industry. There are lots of difficulties in implication of internet technology to health care process. This is because that the characteristics of health care industry is very closed and specific and also the internet technology has the very user-oriented characters. So it is necessary to have the system independent conceptual design method to combine these two characteristics. In this paper a new modified conceptual design methodology will be proposed for the successful implementation of e-health system in korean health care industry. The proposed methodology will be verified its validity and feasibility through AHP method. And the results of this research will be implied as the basis for the development and revitalization of e-Health system in Korea.

In the edge of new jumping up in global market, our construction industry is required to develop a competitive power and new construction market. As a considerable global player, our construction industry and information technology industry are regarded as to achieve more competitiveness and new market by developing fusion technology between information and construction technology. But, practically not only the technologic barrier but unripe developing model, it is time to visualize fusion strategic model and possible area as a constructional point of view. The aim of fusion technology is to increase productivity by reducing labor power and over all life cycle cost and to suggest new market with effective demanding power such as ubiquitous-city. As a successful development model, both the demand driven approach dealing with prompt IT developing speed and a circular leading model boosted by leading group will be key factors.

In this paper, a calculation method of the thermodynamic parameters of cryogenic propellant is proposed when a cryogenic propellant tank is pressurized by gaseous helium(GHe) bubbling. Temperature of cryogenic propellant and mass of dissolved GHe into propellant were analyzed at the various operation of pressurization of tile liquid oxygen(LOX) and hydrogen($LH_2$) tank using helium bubbling. It was evaluated how the GHe bubbling influences to the thermodynamic parameters of LOX and $LH_2$ with results of the analysis. With the proposed calculation method, It will be able to confirm the feasibility of GHe bubbling as a pressurization system of cryogenic propellant tank and to optimize the pressurization system using GHe bubbling.

NTIS(National Science & Technology Information Service) is the first national R&D information knowledge portal service in the world to provide information of government-funded R&D projects and it has been developed by KISTI. This study investigated several limitations of current NTIS information service, analyzed information needs for end users, and then proposed information recomposition and visualization method to satisfy their information needs. For doing this, we firstly clarified the definition of 'end-users' and classified three different groups of general users. We also discriminated various information needs according to three groups and illustrated some examples of visualization results to meet the requirements - 'retrieval simplification' and 'information visualization'. To consider practicality of our proposed method, we suggested implementation plans to utilize existed NTIS services.

Seomin has been used frequently in mass media and political discussion. However, who is Seomin, how to define Seomin, and whether Seomin and middle class are different has been rarely discussed. This study conducted both national level of survey and in-depth interviews and explored how to define Seomin and who respondents think as Seomin. The majority of respondents consider themselves as Seomin and that monthly income is the most important criteria to define Seomin. Seomin was considered as those who have high school education and 200~300(million won) monthly income, live in a rented house, and work as a small-scale self-employer, skilled laborer, and low level of white collar workers. Also, Seomin is a precarious group which can achieve upward or downward mobility and is located between low and middle class. Those who have Seomin identity tend to have pride in their social status and hope for upward mobility rather than depreciate their social status or envy the middle class. In order for Seomin to be able to achieve upward mobility and to maintain pride in current status, diverse social policies are needed. Further analyses on examining characteristics and policy needs of Seomin are needed.

A novel priming discharge technique in which the ramp shaped priming pulse is superposed on the sustain period so that the entire plasma display panel (PDP) is discharged at the same time with a single drive circuit is proposed. From the experimental results, it is ascertained that the priming discharge is ignited only in a pixel in which sustain discharge does not occur and it has been understood that the priming pulse hardly influences the sustain discharge. Moreover, high-speed driving with address pulse widths of 0.7[${\mu}s$] was achieved and a wide address voltage margin of 40[V] was obtained by using the drive method applied the proposed priming discharge technique. In these results, full-HDTV PDP with 1080 horizontal scanning lines can be driven without decreasing the brightness and the possibility of the commercializing is also high because this technology is designed for using the commercialized driver IC.

Recently the building of ultra large container ship are discussed among ship building companies and ship operating company who have a tendency to pursue the advantage of large scale of economy. These tendency will be continued for the time being, if ship-building skill and economical efficiency are available. As the enlargement of container ship size becomes hot issues in ship-building markets, the needs for re-arrangement of accommodation house in large container ship are proposed carefully in some researches. This study examined economical efficiency of re-arrangement of accommodation house in ultra large container ship. The separation between accommodation and engine room is proposed through out drawing works in initial design stage and we examined the merits and demerits of the separation in the view of economical efficiency. The RFR(Required Freight Rate) is considered as the objective function to evaluate the re-designed vessel. The economical benefits are analyzed in the view of ship operator and shipyard respectively.

In this paper, we introduce an energy-efficient opportunistic interference alignment (OIA) scheme that greatly improves the sum-rates in multi-cell uplink networks. Each user employs optimal transmit vector design and power control in the sense of minimizing the amount of generated interference to other-cell base stations while satisfying a required signal quality. As our main result, it is shown that owing to the reduced interference level, the proposed OIA schemes attains larger sum-rates than those of OIA with no power control for almost all signal-to-noise ratio regions. In addition, when both zero-forcing and minimum mean square error (MMSE) detectors are employed at the receiver along with the OIA scheme, it is shown that the OIA scheme with MMSE detection shows superior performance.

Most films have not made by original storytelling. They get their storylines and themes from diverse sources such as novels, comics, performing arts, and previous film products. Comics have become a primary source for film production since 1960s in such nations as Japan and USA. In the contemporary period, this becomes a more visible trend in many countries including Korea, China, and France. Unlike novel, comics combine words with images. Since a comic strip isa graphic medium in which visible images are created in order to express a sequential narrative, it seems more relevant when films adapt original comics in order to recreate new products. The progress of 3D graphics technology enables film creators to realize imagined images in screen, most of which were once imagined only in comics. Keeping an eye on the strength of comics, this study tries to tries to investigate the relationship between a comic strip and its adaptation to film. It will firstly discuss the cases of comics in Korea, which are adapted to film in Korea. And this study will discuss "Le Grand Chef"as a case study in order to investigate what is the difference between original comics and film adaptation.
