하루에도 수많은 제품들이 시장에 출시되고 있고 소비는 점차 양극화되고 있다. 기존 고객의 이탈을 막고 양극화된 소비자를 잡기 위해 고급브랜드나 저가브랜드 모두 끊임없이 신제품을 출시하고 있다. 기업에게 있어 신제품 출시는 기존 고객 유지뿐 아니라 새로운 고객을 유인하는 데 있어 매우 중요한 역할을 한다. 그러나 신제품을 출시하면 소비자들에게 신제품의 이름과 핵심편익을 알려야하는데 이 비용이 만만치 않다. 게다가 신제품이 실패라도 하게 되면 기업이 지불해야 하는 금액은 더 커질 수밖에 없다. 그래서 기업들은 기존에 고객들에게 사랑받고 있는 유명브랜드의 이름을 신규제품에 활용하는 브랜드확장전략을 많이 사용한다. 확장브랜드는 소비자들에게 좀 더 쉽게 선택 받을 수 있기 때문에 소비양극화시대에 매우 중요하다. 이에 본 연구에서는 확장유사성, 출시시기, 메시지 전략이 브랜드 확장에 어떤 영향을 미치는 지를 알아보기 실험을 실시하였다. 연구결과 기존 브랜드와 유사성이 떨어지는 경우에는 구체적인 메시지보다는 추상적인 메시지를 사용하는 것이 더 효과적인 것으로 나타났다. 특히 이런 효과는 출시시기가 가까울수록 더 효과적이었다. 그러나 유사성이 높은 제품으로 브랜드 확장을 할 경우에는 출시시기가 가까울 경우에는 구체적 메시지 위주로, 출시시기가 먼 경우에는 추상적 메시지를 위주로 커뮤니케이션 하는 것이 효과적인 것으로 나타났다. 이런 결과는 기업이 브랜드확장을 할 때 확장 유사성뿐만 아니라 출시시기와 메시지특성을 함께 고려해야 한다는 시사점을 주고 있다.

The performance of an electrodialyzer for concentrating seawater is predicted by means of a computer simulation, which includes the following five steps; Step 1 mass transport; Step 2 current density distribution; Step 3 cell voltage; Step 4 NaCl concentration in a concentrated solution and energy consumption; Step 5 limiting current density. The program is developed on the basis of the following assumption; (1) Solution leakage and electric current leakage in an electrodialyzer are negligible. (2) Direct current electric resistance of a membrane includes the electric resistance of a boundary layer formed on the desalting surface of the membrane due to concentration polarization. (3) Frequency distribution of solution velocity ratio in desalting cells is equated by the normal distribution. (4) Current density i at x distant from the inlets of desalting cells is approximated by the quadratic equation. (5) Voltage difference between the electrodes at the entrance of desalting cells is equal to the value at the exits. (6) Limiting current density of an electrodialyzer is defined as average current density applied to an electrodialyzer when current density reaches the limit of an ion exchange membrane at the outlet of a desalting cell in which linear velocity and electrolyte concentration are the least. (7) Concentrated solutions are extracted from concentrating cells to the outside of the process. The validity of the computer simulation model is demonstrated by comparing the computed results with the performance of electrodialyzers operating in salt-manufacturing plants. The model makes it possible to discuss optimum specifications and operating conditions of a practical-scale electrodialyzer.

Interpreting the phenomenon of Fast fashion that is prevalent these days, this research is meaningful in that it prepares the frame which suggests the vision to read the trend of 2000s and analyzes the property of phenomenon of Fast Fashion in the connection with society and culture. The so[io-cultural property can be largely characterized by consumption orientation, change orientation, efficiency, moment and multiculturism. Analyzing the phenomenon of fast fashion that emerged after 2000 on the basis of such sociocultural background, it is largely classified into imitation, fashionability, disposability, portability, transformation and convergence. Due to the hi-polarization of consumption, people tend to select imitated goods, and people accustomed to speed get interested in the fashionability of all Phenomena. Further, society that is transient and changing rapidly makes the habit of purchasing in disposability. The property of nomad society encourages to keep the habit of portability. Such change-oriented society and rapidly changing life pattern make them adapt in diverse transformation modes of Fast Fashion. Further, multi-cultural world integrates enterprises through combination of all cultures and the convergence of all factors.

양극화와 세대간 계층재생산이 한국 사회의 심각한 사회문제로 여겨지는 상황에서, 동질적인 부모의 배경, 동일한 소득계층, 동일한 학력 간에 끼리끼리 이루어지는 동질혼의 증가가 사회적 주목을 받고 있다. 동질혼의 증가가 사회 이동의 폐쇄성을 강화함으로써 불평등을 심화시키고 세대간 계층 이동을 제한시킬 것이라는 우려 때문이다. 이 연구는 동질혼의 개념을 구성하는 부부의 성취적 특성 및 부모의 귀속적 특성이 가구의 경제적 상태를 대표하는 소득, 소비, 자산에 미치는 영향을 분석하고 있다. 이를 통하여 한국 사회의 세대내 불평등 및 세대간 계층이동성에 영향을 미치는 동질혼의 역할에 대한 실증적 이해에 기여하고자 하였다. 동질혼이 소득과 소비, 그리고 자산에 미치는 영향에 관한 다중회귀분석 결과, 동질혼의 성취적 특성으로는 고학력 동질혼이 소득과 소비 수준을 증가시키는 요인으로 나타났으며, 동질혼의 귀속적 특성으로는 아버지들의 교육적 동질혼이 자산수준을 증가시키는 요인으로 나타났다. 소득과 소비에는 동질혼의 성취적 특성이 영향을 미치는 반면, 자산에는 동질혼의 귀속적 특성이 유의미한 영향을 미치는 것으로 나타나, 세대간 이전이 소득보다 자산을 중심으로 영향을 미치고 있음을 발견하였다. 특히 20-30대 젊은 부부에게는 귀속적 특성이 자산에 대해서만 유의미한 영향을 미친다는 점도 밝혀졌다.

Electrochromic displays offer the possibility of providing high brightness in reflective mode due to the fact that no polarization of the incident or reflected light is required. The use of appropriately roughened reflective layers can enable the diffuse or Lambertian reflection of light. truly imitating the optical nature of paper as a reading medium. Furthermore, the use of an electrochromic system, essentially an electrochemical device, allows for the integration of charge storage layers, endowing such devices with an on-state memory and associated low power consumption. In this paper we describe the $NanoChromics^{TM}$ system and overview the several strategies employed towards the migration of this technology to flexible display formats.

Ferroelectric thin films have attracted much attention for applications in nonvolatile ferroelectric random access memories(NVFeRAM) from the view points of high speed operation, low power consumption, and large scale Integration[1,2]. Among the FRAM, BLT is of particular interest. as it is not only crystallized at relatively low processing temperature, but also shows highly fatigue resistance and large remanent polarization Meanwhile, these submicron ferroelectric capacitors were fabricated by a damascene process using Chemical mechanical polishing (CMP). BLT capacitors were practicable by a damascene process using CMP. The P-E hysteresis were measured under an applied bias of ${\pm}5V$ by using an RT66A measurement system. The electric properties such as I-V were determined by using HP4155A analysers.

We examined the effects of alloying elements such as Fe, Ga, In, Sn, Mg, and Mn on the electrochemical characteristics of Al-based alloys for Al-air batteries by potentiodynamic polarization tests and electrochemical impedance spectroscopy. The corrosion potential of an Al anode was lowered by the addition of Ga and Sn, resulting in an increase in the cell voltage compared with a pure Al electrode. Fe was not beneficial to improve the electrochemical properties of the Al anode in that it caused a decrease in the cell voltage and reduced corrosion rate slightly. In, Mn, Sn, and Mg decreased the corrosion rate of the Al alloys, while Ga enhanced corrosion significantly and accelerated consumption of the anode.

Energy storage devices have received a keen interest throughout the world due to high power consumption. A large number of research activities are being conducted on electrochemical double layer capacitors (EDLCs) because of their high power density and higher energy density. In the present study, an EDLC was fabricated using natural graphite based electrodes and ionic liquid (IL) based gel polymer electrolyte (GPE). The IL based GPE was prepared using the IL, 1-ethyl-3-methylimidazolium trifluoromethanesulfonate (1E3MITF) with the polymer poly(vinyl chloride) (PVC) and the salt magnesium trifluoromethanesulfonate (Mg(CF₃SO₃)₂ - MgTF). GPE was characterized by electrochemical impedance spectroscopy (EIS), DC polarization test, linear sweep voltammetry (LSV) test and cyclic voltammetry (CV) test. The maximum room temperature conductivity of the sample was 1.64 × 10^-4 Scm^-1. The electrolyte was purely an ionic conductor and the anionic contribution was prominent. Fabricated EDLC was characterized by EIS, CV and galvanostatic charge discharge (GCD) tests. CV test of the EDLC exhibits a single electrode specific capacitance of 1.44 Fg^-1 initially and GCD test gives 0.83 Fg^-1 as initial single electrode specific discharge capacitance. Moreover, a good stability was observed for prolonged cycling and the device can be used for applications with further modifications.

Artificial intelligence (AI) has become the hottest topic in information and communications technology (ICT) in recent years. Along with the advancement of AI technology, technologies such as big data, cloud, and high-speed wired and wireless communication are being applied to existing media areas in earnest, affecting all parts of the media value chain from content production to consumption. AI technology is now spreading across the media industry faster than any other industry. In the future, the gap between those with and without AI technology will widen, further deepening the polarization of the media ecosystem. Media intelligence, which combines media and AI technologies, is now perceived as essential, not optional. In this paper, we examine the current status of technology development and standardization by major domestic and foreign institutions on how AI is being utilized in the media industry. In addition, we discuss what technology should be developed to lead media intelligence.
