The purpose of this study is to establish academic identity as well as produce human resources that industries need by grasping curriculum of the departments related beauty focusing on Korean colleges (junior colleges and four year course colleges), analyzing examples of advanced countries and suggesting their developmental direction. For the research method, the reference period of curriculum in Korean colleges was from Jul. 05th, 2011 to Aug. 05th, 2011. the investigation method is as follow: first, the curriculum of the departments related to beauty which were registered in the web sites were investigated. Second, the documents were received by fax and Email from each department after calling it. Third, questions and answers were done in reference to majors on the phones. these methods are intended for 65 junior colleges and 16 four year course colleges (total 81 ones). It clarified that lifelong education centers and the graduate courses were ruled out. the statistical analysis about data which were investigated like this were done by the frequency analysis. The results which examined the major subjects of Make-up focusing on Korea and foreign countries are as follow: First, the result which examined the major and theory subjects of Make-up has found that there are the human body theory, the equipment theory, the marketing theory are the management theory in Korean junior colleges and physiology/chemical, management, marketing and equipment product were treated in four year course colleges of Korea. As for foreign colleges, the subjects related to history and culture are mainly treated as the theory courses and their purpose is to cultivate basic knowledge of the fields which are mainly connected to Make-up including plays, movies, TV and studios. Second, the result which examined practice subjects of Make-up major has found that practice subjects of the total ones are of great importance in junior colleges. And it could be found that the Make-up field is of little importance as it is not independent and exists with the hair and skin fields in one department in the four year course colleges. Especially, in the foreign countries, the more detailed and professional subjects including classes which treat digital media, studio technologies, production, wigs and the special effects were treated by the field class system and these characteristics implies that Korean curriculum should be changed in the future. Based on this analytical results of investigation, this researcher tried to propose the developmental direction of Korean curriculum in the future.

This paper examines the recently empirical test for the two types of endogenous growth models, which one is more fitted to real data. We adopt the non-stationary panel data methodologies for seeking empirical implication by using productivity and R&D data in the OECD over the past two decades. The Empirical tests show that there is a robust relationship Total Factor Productivity and R&D variables implied by semi-endogenous growth model. The relationship suggested by fully endogenous growth theory, however, is sensitive to R&D variables. Therefore, the estimation results provide empirical evidence in favour of endogenous growth theory of R&D expenditure role for sustaining economic growth. The sustained Total Factor Productivity, however, is maintained by more increasing R&D inputs for overcoming diminishing return to R&D efforts.

With the development of virtual and augmented reality technologies, the metaverse, a digital world that provides an immersive feeling like the real world, is overgrowing. Many IT companies such as Naver, Facebook (Meta), and NVIDIA are developing innovative technologies and launching the Metaverse platform and related products on the market. However, even though it is a new business in which many global big tech companies are aggressively investing, the results are not yet precise compared to the market expectations, and the rate of increase in the number of users is gradually slowing down. This can be attributed to the lack of consideration and understanding about how to grow the metaverse ecosystem and operate & harmonize various users/components from the time the metaverse platform was designed. In order to propose a better solution to these problems, this study adopts the yin-yang and five elements theory, which was created to understand the operation logic and logic of the human world for thousands of years. This research would like to propose a theory of double lines-five elements by defining two essential spaces of the metaverse platform, online and offline, and five essential elements constituting the metaverse platform. This study intends to provide a theoretical lens on how to design and operate a platform through the double lines and five elements theory and the concept of coexistence and polarity between the five elements.

The current study deals with the size-dependent free vibration analysis of graphene nanoplatelets (GNPs) reinforced polymer nanocomposite plates resting on Pasternak elastic foundation containing different boundary conditions. Based on a four variable refined shear deformation plate theory, which considers shear deformation effect, in conjunction with the Eringen nonlocal elasticity theory, which contains size-dependency inside nanostructures, the equations of motion are established through Hamilton's principle. Moreover, the effective material properties are estimated via the Halpin-Tsai model as well as the rule of mixture. Galerkin's mathematical formulation is utilized to solve the equations of motion for the vibrational problem with different boundary conditions. Parametrical examples demonstrate the influences of nonlocal parameter, total number of layers, weight fraction and geometry of GNPs, elastic foundation parameter, and boundary conditions on the frequency characteristic of the GNPs reinforced nanoplates in detail.

Theories and concepts emerging in new media environment are influencing the field of current spatial design. Art and technology have always coexisted, not but they are differentiated in two parts. They show new communicational paradigm in terms of supplementary position each other. The fact that examining the expression method and the communicational structure of today's new media art will be an analytical tool which analyzes the concepts of contemporary spatial design. For this, we attempt to use the Bolter and Gusin's remediation theory as analytical tool. First of all, we consider its theoretical aspects, and then, classify them according to the creation method, and investigate the characteristics of expression according to their types. We prepared an framework of analysis using the Remediation theory and its traits. We reviewed the relations between new media and spaces concerning remediation. After researching, we could analyze the cognitive aspects between new media and spaces as immediacy, and recognize the operational aspects of visual image as hypermediacy. Through the analysis, we could recognize the traits that digital environmental simulacres, sense of telepresence, and non-linear hypermediacy etc. remediate with repeating of mediation of mediation.

The design and construction of special purpose vessels such as drillship and shuttle tankers have been increased. These vessels install the DPS(dynamic positioning systems) to maintain the position and heading for long-time operation. This paper deals with the experimental method for model-based DP system and the control theory and filter algorithms. In this experiment, the length of model ship is 4 meters and it has three thrusters to maintain the position. The ability of tracking along the given course and keeping of heading in waves are confirmed. For the calculation of thruster input the PID control theory are adopted and the effects of PID gain were investigated. To estimate the low frequency motions Kalman filter and digital filter were used and their effects were investigated.

This paper focuses on the control of bidirectional power flow in the electric shipboard power systems, especially in the Medium-Voltage Direct Current (MVDC) shipboard power system. Bidirectional power control between the main MVDC bus and the local zones can improve the energy efficiency and control flexibility of electric ship systems. However, since the MVDC system contains various nonlinear loads such as pulsed power load and radar in various subsystems, the voltage of the MVDC and the local zones varies significantly. This voltage variation affects the control performance of the bidirectional DC-DC converters as exogenous disturbances. To improve the control performance regardless of uncertainties and disturbances, this paper proposes a novel controller design method of the bidirectional DC-DC converters using $L_1$ control theory and intelligent optimization algorithm. The performance of the proposed method is verified via large-scale real-time digital simulation of a notional shipboard MVDC power system.

This paper deals with operational characteristic analysis of a single-phase PCS (Power Conditioning System) for PV (Photovoltaic) power generation system with AF (Active Filter) function. The theory of dq transformation has been applied to the control strategy of a single-phase PV power generation system to implement the AF function. Application of the virtual two-phase using phase-shift makes it possible to use the dq theory for the single-phase PV power generation system. The authors are sure that the proposed system is a very useful to compensate harmonics caused by nonlinear loads in a single-phase utility system. In this paper, not only a theoretical aspect of the single-phase PV-AF system is discussed, but also the DSP (Digital Signal Processor) based experiment results are presented to demonstrate the effectiveness of the single-phase PV-AF system.
