The Roman thinker, Cicero said, "The Nations that rule the sea, rule the world". In the world history, the countries done critical roles, have emphasized the importance of the sea. The world history is called as the histories of the countries which governed the sea, such as Phoenicia, Greece, Carthago, Roma, Portugal, Spain, England, and USA. The sea is not only the political, economical, social and cultural basis, serving as the origin of resources and channel of communication, logistics and distribution but also the area of dreams and imaginations and ground of potentiality and visions. This paper reviewed the major countries and their histories to realize the vision of Korea, super power country of maritime and fishery. Main maritime policies and its core issues and prospects of Korea were reviewed. And on the basis of these reviews, the vision of super power country of maritime and fishery was suggested. The vision, the 5th super power country of maritime and fishery in 2020, and 10th country of maritime technology level in 2020 and their details were proposed also. For achieving the vision, the resurrection of MOMAF is necessary and its reasons and 5 necessities were suggested. And the directions of the resurrection of MOMAF were proposed in terms of two viewpoints, policy/functional and institutional basis. I think Korea, the super power country of maritime and fishery, can be realized only when MOMAF may be resurrected.

The major purpose of this paper is to analyze the evolution of the presidential system in South Korea during the past three decades ever since the country's democratization in 1987 from the comparative institutional perspective. As imperial presidentialism during the so-called three Kim's era(1987-2003) disappeared right after the political retirement of the three Kims in 2003, then president-centered presidentialism emerged during the post-three Kim's era, since the country's recent three presidents possessed their relatively low-level of partisan power in terms of their control of National Assemblies and their respective presidents' parties during their presidencies. South Korea has now a strong possibility to transform the current president-centered presidentialism into the American-style separatist presidential system in the near future, since the country's National Assembly has continuously been making its efforts to function as an effective governing body being compatible with the American Congress. In addition, the country's judiciary branch has effectively been playing a political role like the US supreme court ever since the country's democratization in 1987. It is also emphasized that South Korea's civic society is currently playing as a guardian of democracy through its effective and responsive political participations in many public sectors for promoting civic liberties, public welfare, and other democratic values. South Korea now needs to carry out constitutional revisions, political reforms of legislative system, party system, and electoral system as well as correct some contradictory political understandings and habits in a way to transform the current president-centered presidentialism into American-style separatist presidential system in the near future.

The rapid development in modern industrialization pollutant the water and atmospheric air across the globe that have a major impact on the human and livings health. In worldwide, every country government increasing the importance to improve the outdoor air pollution monitoring and control to provide quality of life and prevent the citizens and livings life from hazard disease. We proposed the environmental dust level detection method for outdoor facilities using sensor fusion technology to measure precise micro-dust level and monitor in realtime. In this proposed approach use the camera sensor and commercial dust level sensor data to predict the micro-dust level with data fusion method. The camera sensor based dust level detection uses the optical flow based machine learning method to detect the dust level and then fused with commercial dust level sensor data to predict the precise micro-dust level of the outdoor facilities and send the dust level informations to the outdoor air pollution monitoring system. The proposed method implemented on raspberry pi based open-source hardware with Internet-of-Things (IoT) framework and evaluated the performance of the system in realtime. The experimental results confirm that the proposed micro-dust level detection is precise and reliable in sensing the air dust and pollution, which helps to indicate the change in the air pollution more precisely than the commercial sensor based method in some extent.

The statistic processing of collected data utilized the SPSS version 15.0 the statistical package program through data coding and cleaning process and performed the frequency analysis, reliability analysis, t-test, one way analysis of variance, Pearson analysis, and regression analysis. The relationship of the office given condition actual condition of the guard about the national important facility and job satisfaction degree was classified into the interpersonal relationship, task characteristic, office environment, and complement factor and the difference of the job satisfaction degree according to the general characteristic was verified. If the conclusion obtained through the method of study described in the above looked at, for as to general tendency, the low wages and poor field environment was continued. In the general characteristic, the man was higher than the excitation about the job satisfaction level. As there was lots of the age and the scholarship was low, the age was high. And as there was lots of the career and income, the police of a petition or search and guide staff was high and the job satisfaction degree in which relatively the employee and the other job group is high so that the case of being the former student incidence can be the poorest was shown rather than the facility security agent. As the interrelation analysis result job satisfaction was high, the change of occupation pseudo was low and the organizational commitment degrees was increased. The regression analysis result job satisfaction degree was exposed to reach the meaningful effect on the change of occupation pseudo and organizational commitment. It had an effect on the change of occupation pseudo as the task characteristic and office ambient level was low. It had an effect on the organizational commitment as the extend of satisfaction about the task characteristic and interpersonal relationship, complement, and office ambient level were high. If the research result of this time is integrated, the support of the political system including the interpersonal relationship thesis between top and bottom of the organized I and substantial complement actualization is urgently needed between the office given condition improvement effort in the country important facility defense manpower field and police of a petition and special guard.

The purpose of this review is to identify factors that affect the quality of cyber universities. While the previous studies focused on the university-level factors, the review revealed that the country-level, social-level, and individual-level variables are also important factors influencing the quality of cyber universities organically and systematically. Therefore, the current study asserts that additional predictors should be added with regard to its systemic structure. These variables would include basic educational environment (e.g., teachers, staff, educational system), related regulations, management system, student willingness to participate in learning and their motivation, the government's awareness of cyber universities and polity support, and societal recognition/assessment of cyber universities.

The outage cost assessment has an important position for determination of the optimal level or optimal range of reliability for power system expansion planning. Establishing the worth of service reliability is a very difficult and subjective task. While the utility cost(reliability cost) will generally increase as consumers are provided with higher reliability, the consumer costs(reliability worth) associated with supply interruptions will decrease as the reliability increases. The total costs to society are the sum of these two individual costs and the optimum or target level of reliability is achieved at minimum point of the total cost curve. This paper addresses the role, need and assessment algorithms and methodologies of the outage cost in power system expansion planning. In a case study, the outage cost has been assessed using macro approach for our country 15years(1986-200l) in the case study. Additionally, determination processing of optimum reliability level is presented in another case study with the five buses MRBTS.
