The next local election for Jeollabuk-do will be held in 2010. In preparation for this, we conducted a study to observe whether or not if minute regionalism occurred during the fourth "Nationally coordinated local election" which was held on May 31st in 2006. This study is based on Jeollabuk-do provincial governor election data. For this, we introduced a RS index which is used to measure how evenly each candidate for governor of the province received votes, and chi-statistics that measure each candidate's local intimacy. Further more, we checked out whether minute regionalism occurred or not by putting to practical use correspondence analysis. As a result, we could confirm that minute regionalism occurred to a few candidates. After reviewing many measurements, we found that a RS index's validity is not high.

This study was aimed to analyzing the fashion style worn during the election campaign in the 16-18 Korea presidential candidates. In order to derive a comprehensive fashion style of each candidate it was classified as outfits, items, colors, patterns, accessories and the like. Research data was collected through literature, newspapers, Internet sites, etc., and SPSS statistical package was performed. In research data, 16 presidential candidates photographs were 87, 17 presidential candidates photographs were 82, 18 presidential candidates photographs were 155 as photograph by exposure to the media during each presidential campaign. The results of this study are as follows: In the fashion style of presidential candidates, male candidates mainly dressed in a tie and suit, but the 18 candidates dressed in casual wear unlike previous candidates. In tie color, 16 appeared in the red series, 17 election and 18 election appeared in blue series. Female candidate, Park Geun-hye candidate dressed in the combination of a jacket and blouse and pants. Therefore fashion style of presidential candidates got a strong symbolic image functions as political lines, ideologies, beliefs, and the campaign promises. Because describing the fashion style of candidates based on the statistical result, it requires attention to generalization.

Leader election is an important problem in developing fault-tolerant distributed systems. As a classic solution for leader election, there is Garcia-Molina's Bully Algorithm based on time-outs in synchronous systems. In this paper, we re-write the Bully Algorithm to use a failure detector instead of explicit time-outs. We show that this algorithm is more efficient than the Garcia-Molina's one in terms of the processing time. That is because the Bully_FD uses FD to know whether the process is up or down so fast and it speed up its execution time. Especially, where many processes are connected in the system and crash and recovery of processes are frequent, the Bully_FD algorithm is much more efficient than the classical Bully algorithm in terms of the processing time.

Short-term electric load forecasting of power systems is essential for the power system stability and the efficient power system operation. An accurate load forecasting scheme improves the power system security and saves some economic losses in power system operations. Due to scarcity of the historical same type of holiday load data, most big electric load forecasting errors occur on load forecasting for the holidays. The fuzzy linear regression model has showed good accuracy for the load forecasting of the holidays. However, it is not good enough to forecast the load of the election day. The concept of the load variation rate for the load forecasting of the election day is introduced. The proposed algorithm shows its good accuracy in that the average percentage error for the short-term 24 hourly loads forecasting of the election days is 2.27%. The accuracy of the proposed 24 hourly loads forecasting of the election days is compared with the fuzzy linear regression method. The proposed method gives much better forecasting accuracy with overall average error of 2.27%, which improved about average error of 2% as compared to the fuzzy linear regression method.

Till now, much progress has been made in election forecasting. But fixed-line telephone survey has limitations, because it has become more and more difficult to get a representative sample, Exit poll has been considered to provide a new solution. From the beginning, exit poll provided more accurate predictions than those based on surveys using fixed-line phone. In 2002 presidential election, prediction based on exit poll was perfect. Its predictive error was zero. This paper describes how the exit poll was done in 2002 presidential elections. Specifically, we are to show the estimating procedures as well as sampling and polling process. Among many factors, sampling procedure has been fond to be the most important factor in exit poll accuracy.

According to the double-phase cluster-head election method (DCE), the final cluster heads (CHs) sometimes are located at the edge of cluster. They have a long distance from the base station (BS). Sensor data is directly transmitted to BS by CHs. This makes some nodes consume much energy for transmitting data and die earlier. To address this problem, energy efficient multi-hop cluster-head election strategy (EEMCE) is proposed in this paper. To avoid taking these nodes far from BS as CH, this strategy first introduces the distance from the sensor nodes to the BS into the tentative CH election. Subsequently, in the same cluster, the energy of tentative CH is compared with those of other nodes, and then the node that has more energy than the tentative CH and being nearest the tentative CH are taken as the final CH. Lastly, if the CH is located at the periphery of the network, the multi-hop method will be employed to reduce the energy that is consumed by CHs. The simulation results suggest that the proposed method exhibits higher energy efficiency, longer stability period and better scalability than other protocols.

In this paper, the Constitutional Court's ruling through the SNS was virtually guaranteed the freedom of election campaign through, though, still a large portion of campaign restrictions on public election law provisions exist to this forward in the election is likely to cause a lot of legal problems. In this paper, the Constitutional Court's ruling through the SNS was virtually guaranteed the freedom of election campaign through, though, still a large portion of campaign restrictions on public election law provisions exist to this forward in the election is likely to cause a lot of legal problems. Moreover, in the mean time the campaign and which in the course of the election campaign through the SNS, the infinite potential of the growing point than any point spread from the SNS and freedom of election campaign through public election law with regard to the limitation of the diffusion of false facts, awards, a number of problems are likely to occur. You've been in this business and disseminate false guilt disparage precandidacy for true-false, as well. He should be able to reach a specific goal you want to defeat through the dissemination of information which is specified as a crime for this strictly for the fact that disseminate false, rather than to interpret it is the judgment of the Court in that judgment against have been made. Therefore, this strict interpretation of the law and the need to revise or delete before I would like to discuss about. The legislation would repeal the cull of Ron sang first of all point out the issue through analytics. First, the purpose of the data protection Act provides limited interpretation to fit in this world of sin. Secondly, this sin is committed for the purpose of prevention, since the purpose of the objective in this case of sin and the need to interpret strictly. Why I am the Internet space in the case of so-called tweets from followers, this means in some cases done without a lot of the stars because of this, there will be a limit to the punishment of sin, this is obvious. And, in the long-awaited Constitutional Court ensures the freedom of election campaign through SNS and free election in the country, even in the limited sense interpretation opens the chapter of communication is needed. This ensured the freedom of expression will be highly this is a mature civil society that will be imperative.

In this study, the undeniable digital multi-signature scheme based on the discrete logarithms is proposed. The proposed multi-signature scheme satisfies undeniability and is secure against active attacks such as fabrication and denial of multi-signature by signers. It is suitable for electronic election scheme in which several administrators are required. Especially in case of dispute among voters and administrators, the proposed scheme can resolve it due to the undeniable property. It can provide fair electronic election by minimizing the role of voting center, and can enable user-oriented electronic election.
