Since 2012, the government has attempted to stimulate the human resources businesses need and substantial R&D technology by promoting "Leaders in INdustry-university Cooperation" (LINC). They use the natural the relationship between industry and university develop and spread a variety of industry-university cooperation for mutual growth model leading universities and industries of the region. More than recent cooperation education, at the level of practical use, field oriented talent needed in the industry demand Internationalized talent which can become members of a global community cultivated with International perspective and insight. Furthermore, while currently each university's circumstances and the position is different, and while this strategy, each unique, individual, specific international level's Cooperation Education Plan is Established and operating actively, Governments and businesses will be able to train desired international academic centers' advanced talent. We have come to hope that this will act as an important factor in furthering national competitiveness.

We have studied the astigmatism according to the bevel position and the tilting(pantoscopic) angle of decentered spectacle lens for prism prescription. For prism prescription, generally we make a general spectacle lens into decentered spectacle lens. At this time the bevel position of decentered lens is a important matter, because the difference between optic axis and visual axis occur aberrations. Using the calculation we find that the case that the axis of bevel rotation band passes the front curvature center of (+) lens has a smaller astigmatism than the case that the axis of bevel rotation band passes the rear curvature center of (+) lens and that the case that the axis of bevel rotation band passes the rear curvature center of (-) lens has a smaller astigmatism than the case that the axis of bevel rotation band passes the front curvature center of (-) lens. We find the lens with higher refraction index has a smaller astigmatism.

The spermatozoa of Platichthys stellatus is relatively simple cells composed of a spherical head, a short midpiece, and a tail, as in most Pleuronectiformes. The ultrastructure is characterized by the following features: a round nucleus with a deep nuclear fossa, the centriolar complex located at a right angle to each other, a short midpiece, a tail with paired lateral ribbon and no acrosome. However there are some minor morphological differences, including the appearance and number of the mitochondria, the shape and size of the nuclear fossa and the structure of the basal body. Especially the basal body structure consisting of a basal foot, a rootlet and nine alar sheets structures varies considerably in different species. It can be used as indicator of relationships in Pleuronectiformes because minute morphological differences might have functional and evolutionary significance. In conclusion, the spermatozoa of P. stellatus show a certain structural homogeneity and provide support for the concept that ultrastructural features of spermatozoa can be useful in taxonomic studies of Pleuronectiformes.

In this paper, a method of ISAR geometric calibration is represented by using impulse-radio UWB radar. The ir-UWB is good for using a signal processing in time domain, so, it does not occur a multi-path or coupling problem. If a signal that between antennas and target is assumed a plane wave, a center of rotation in ISAR geometry model can be estimated by using point target. Before image is reconstructed with sinogram, the center of rotation can be calculated by using least square fitting. This method can be obtained a more contrast image, and a maximum value of entropy of image. The method, that estimates a center of rotation in received data, will be used a initial setup of instruments or a periodic compensation to reconstruct image. It would be useful in medical, security and surveillance imaging equipments that have a fixed geometry.

Many of the universities in Korea recently is changing the school policy oriented from the supply approach to the demand as the case of business companies. Customer orientation is the key point of the customer satisfaction. But there are few studies focused on the satisfaction of students as a customer. In this paper, we studied the components of satisfaction in university life, the factors affecting on the satisfaction of students, and the relationship among them. The principal components of satisfaction in university life are services related to the activities of students, the utilization of welfare facilities, curriculum, the adminstration on students, and the department office. Factors affecting on the satisfaction of students are expectation, pride, self evaluation on learning, and special activities. Demographic variables, for example, sex, grade, colleges, and so on are also important factors. We also found the fact that the pride was the most important factor, and it gives positive drive on the satisfaction of students in university life. It gives us the important implication to the school policy.

Opening and regional economic integration are characteristic of global economic trends that have been made since the 1990s. Accordingly, all economic blocs of the world are largely reorganized into three poles, European Economic Bloc, American Economic Bloc and Northeast Asian Economic Block which are respectively led by EU, the United States and the rapidly emerging economic power, China. Considering this direction of global economy, the current status of Northeast Asia, China's unprecedentedly enormous port development project and Japan's introduction of an epoch-making port policy towards the restoration of its port competitiveness, Korea is urgently need to take its own initiatives and positive actions that can cope with the above situations. The purpose of this study is to propose ways of strategic cooperation for Korea-Japan joint development. For the purpose, this researcher provides the concept and preconditions of hub-port, investigates hub-port development strategies of rival companies in Northeast Asia and discusses the potential of the development of the Korea-Japan Strait Economic Zone which is located between Busan port and Japan's Honshu(Simonoseki port) and Kyushu(Kitakyushu port).

The horizontal force acting on a work roll was examined. This force results from the contact force between the work roll and backup roll in a backup-roll-drive 4-high cold-rolling mill. This horizontal force bends the work roll horizontally and therefore exerts reciprocal action on the roll-gap contour. An analytical model for predicting the horizontal force acting on a work roll, which generates a mean value in the steady state, was presented. The material used for the analysis was high-silicon steel (about 3% Si). A three-dimensional finite element (FE) model was also employed to investigate the non-steady-state behavior of the horizontal force. Results showed that the horizontal force varied with the off-center distance between the work roll and backup roll. In addition, the optimal off-center distance was determined to minimize the horizontal force.

"The Candle Revolution" impeached the Park government and elected the Moon government. The candlelight protesters demonstrated public anger associated with accumulated corruption and deep-rooted irregularities. Complete political reform is required to perform deep fundamental reform. It aims to transform democracy in a way that is more inclusive. Inclusive democracy contributes to making welfare state stronger. Inclusive democracy is made possible by proportional representation that allows progressive parties more seats and leverages. Proportional representation systems are characterized by higher degrees of redistribution and larger welfare state. Constitutional reform has to be focused on introducing parliamentary government. "Imperialistic" presidential system in Korea has no mechanism of checks and balances which are key characteristics of presidential systems. It has failed to attend the poverty and social inequality arising from globalization and neoliberal change since 2000s. Parliamentary government is supposed to deliver social policy when parties are more disciplined than in presidential system where political parties remain weak.

This study is the identify of influence in the social adjustment stress on foreign female immigrants in Korea. the study is like followings: First, offering the opportunity of employment will increase social activity of foreign female immigrants in Korea, and it will be helpful for their adaptation in Korean society. Second, the service of supporting family should be provided for settlement of foreign female immigrants in Korea, and proper education for affirmative adaptation of them in all spheres of home life, language, culture and it should be performed through their family. Third, systematic service of social welfare should be offered. The adoption of the system which overcome geographical limitation and can provide the service to needed people is required. In addition, for foreign female immigrants in Korea who cannot receive basic Korean language's education because of geographical limitation, it will be another solution which creates programs about Korean language's education. Finally, for understanding culture shock and keeping social relationship, the plans of supporting foreign female immigrants in Korea are required.

Two output ports of $90^{\circ}$ hybrid-coupler are generally the same output power with $90^{\circ}$ phase difference. But, Two output ports of $90^{\circ}$ hybrid-coupler must be the different output slope characteristic about frequency because of the different electrical length. In $90^{\circ}$ hybrid-coupler being the same power distribution, 3-dB power distribution at two output ports only exists near the center frequency. And, the output power difference between two output ports increases in accordance with the further away from the center frequency. This paper proposes $90^{\circ}$ hybrid-coupler being the similar output slope characteristic of two output ports in wideband to modify the ${\lambda}/4$ transmission line of $35-{\Omega}$ characteristic impedance between input port and output port near input port. The power difference between two output ports of the proposed circuit is below 0.2dB over 20% bandwidth of the center frequency in ADS(advanced Design System).
