The research is centered towards analyzing the differentiation of the characteristics and organization of programming strategy and channel positioning by selecting Korean International Public Relations Broadcasting Stations Arirang TV and KBS World. According to the results, Arirang TV positions Korean culture content-implied educational programs as their strategy while KBS World places the main programs of KBS1, 2TV with many entertainment programs such as dramas and entertainment shows. Arirang TV's programming strategy is well-fulfilling the purpose of promoting Korea's culture contents by organizing their programming with documentaries, tourist information, and daily living information. On the other hand, KBS World works as the agent of the spread of the Korean Wave by filling their program with dramas and K-pop programs such as . Due to the difference in programming strategy of these two broadcasting stations, Arirang TV has positioned itself as a diplomatic channel to spread Korean culture and KBS World a channel representing the Korean Wave. However, there are problems of inefficiency due to recurrent investments because of the fact that both broadcasting stations' programming strategy is to promote Korean culture and spread the Korean Wave by aiming similar targets such as foreigners or overseas Koreans.

Educational Programming Language (EPL) should be learner-friendly and easy to use. Dolittle, an object-oriented educational programming language (EPL), offers programming environment which can be programmed in Korean(Hangul). However, since some Dolittle commands are not appropriate to elementary and middle school students, it shows limitations for learners to express programming process. In this paper, we developed a set of 1:n multi-reserved words which are able to program with Korean linguistic characteristics as well as considering learners' differences, preferences, and applicable areas. The conclusion in the paper showed that programming with this 1:n multi-reserved words helped learners concentrate on problem solving regardless of the reserved words.

Physical computing is the concept of expanding computing to humans, environments, and objects. It draws attention as a programming learning medium based on physical outputs in integration of hardware and software. This study developed a programming learning model based on interactive prototyping using the characteristics of physical computing with a high degree of technical freedom and analyzed its learning effect in an experiment. To examine the effect of the experimental treatment, this researcher divided fifty nine 5th-grade elementary students into an experimental group and into a control group. the interactive prototyping programming learning model was applied to the experimental group, and a linear sequential programming learning model was applied to the control group. Information Science Creative Personality Test was conducted before and after the experimental treatment. Analysis of Covariance was conducted with the pre-test scores of the two groups. As a result, it was proved that there was the effect of learning at the significance level of .05. It indicates that the physical computing based interactive prototyping programming learning model is applicable to the programming learning for 5th-grade elementary students.

The new national K-12 Information subject curriculum which will be effective in year 2010 includes algorithm and programming sections. Programming languages in K-12 are more effective the Educational Programming Language (EPL) than general language, because it focuses on developing problem solving ability rather than training a programmer. Therefore, it is necessary to study for suitable EPL in Korean K-12 curriculum. In this study, we studied and analyzed various types of EPLs available and strategies to apply them to the new national curriculum. First of all, we chose 26 educational programming languages and analyzed their characteristics and functions. Also, we investigated associations between key factors of the new Information curriculum and each language and suggested a proper language for their students' level. Finally, we considered possible problems and suitability to Korean K-12 students. The result of this study help us to choose what is the proper EPL and to consider applicability and criteria of EPLs.

The Main object of this research is directed to LG Oil company harbor in kwangyang-hang, where various ships ranging from 300 ton to 48000ton DWT use seven berths in the harbor. This harbor suffered from inefficient and unsafe management procedures since it is difficult to set guidelines for arrival and departure of ships according to the weather conditions and the current guidelines dose not offer clear basis of its implications. Therefore, it has long been suggested that these guidelines should be improved. This paper proposes a decision-support system, which can quantitatively decide the possibility of entry or departure on a harbor by analyzing the weather conditions (wind, current, and wave) and taking account of factors such as harbor characteristics, ship characteristics, weight condition, and operator characteristics. This system has been verified using 5$_{th}$ and 7$_{th}$ berth in Kwangyang-hang harbor. Machine learning technique using genetic programming(GP) is introduced to the system to quantitatively decide and produce results about the possibility of entry or arrival, and weighted linear associative memory (WLAM) method is also used to reduce the amount of calculation the GP has to perform. Group of additive genetic programming trees (GAGPT) is also used to improve learning performance by making it easy to find global optimum.mum.

The three-dimensional (3-D) NAND flash structure with fully charge storage using edge fringing field effect is presented, and its programming characteristic is evaluated. We successfully confirmed that this structure using fringing field effect provides good program characteristics showing sufficient threshold voltage ($V_T$) margin by technology computer-aided design (TCAD) simulation. From the simulation results, we expect that program speed characteristics of proposed structure have competitive compared to other 3D NAND flash structure. Moreover, it is estimated that this structural feature using edge fringing field effect gives better design scalability compared to the conventional 3D NAND flash structures by scaling of the hole size for the vertical channel. As a result, the proposed structure is one of the candidates of Terabit 3D vertical NAND flash cell with lower bit cost and design scalability.

This paper presents a new linking methodology of direct load control(DLC) and unit commitment(UC) considering system spinning reserve characteristics. To consider system spinning reserve characteristics, we formulate new constraints. And to link DLC and UC, we employed 3-Dimensional dynamic programming which has DLC state, UC state, and stage. As a result, economical DLC and UC schedule of the power system is possible. This method is applied to the test system, and the usefulness of the method is verified.

Electrical characteristics of split-gate flash EEPROM with triple polysilicon is investigated in terms of effects of floating gate and offset gate. In order to search for t the effects of offset gate on programming characteristics, threshold voltage and drain current are studied with variation of control gate voltage. The programming process is believed to depend on vertical and horizontal electric field as well as offset gate length. The erase and program threshold voltage are found to be almost constant with variation of control gate voltage above 12V, while endurance test indicates degradation of program threshold voltage. With increase of offset gate length, program threshold voltage becomes smaller and the drain source voltage just after program under constant control gate voltage becomes higher.
