A more detailed design of offset system is needed according to the emission trading system started in 2015. This study aims to estimate the supply of potential offset that can be secured by expanding high-efficiency household electric appliances. The target commodities for analysis are three different householding electric appliances: TV, washing machine, electric fan, refrigerator and air conditioner. By using the ARDL model, we estimated the coefficients of diffusion of these high-efficiency appliances from 2016 to 2022. Then, the potential supply of offset was drawn by calculating the amount of electricity saving by efficiency improvement and by applying the rates of carbon exchange. Supposing that the electricity savings rates of high-efficiency appliances are each 10% and 20%, the accumulated carbon decrement in 2022 was respectively $361,899CO_2t$ and $723,797CO_2t$. The appliance that showed the biggest carbon decrement was air conditioner, and the second biggest was refrigerator and the next was TV, followed by washing machine, electric fan.

Customer Relationship Management (CRM) is a corporate marketing strategy maintaining and managing customers. And with CRM companies maximize the customer's value through a series of processes of new customer retention, VIP customer retention, customer value increase, potential customer activation, and customers for lifetime by collecting the customer information and taking advantage of it effectively. In particular, as the competitive environment is changing rapidly and getting more intense, maintaining the customer retention through customer churn management becomes more important in order to increase the customer value for maximizing the company's profit and to build up the relationship with customers. For example, the financial industry has managed the customer churn with the concept of customer segmentation. Recently the customer retention and churn management is becoming increasingly important in all business fields as well as financial industry since the companies expect the effect of preventing the customer churn by identifying characteristics of customers. However, despite the increasing interest and importance of the management of the customer churn, not many of studies are systematically executed by analyzing the data of customer churn. In this study we analyze the actual data of CRM activities for the customer retention, specifically the data of TV home-shopping. By doing so, we hope to identify the differences of demographic attributes and transaction specific characteristics in consumer behaviors between the churning customer and the retained customers. In addition, we try to find out the variables which can impact the churning of the customers and to predict the churn rate of individual customer through our proposed model of customer churn. In the end, based on our findings we suggest the possible marketing strategies for TV home-shopping companies.

In this paper, we implemented and analyzed a wireless power transfer (WPT) system with a CSPR topology. CSPR refers to constant current source, series resonance circuit topology of a transmitting coil, parallel resonance circuit topology of a receiving coil, and pure resistive loading. The transmitting coil is coupled by a magnetic field to the receiving coil without wire. Although the electromotive force (emf) is small (about 4.5V), the voltage on load resistor is 148V, because a parallel resonance scheme was adopted for the receiving coil. The implemented WPT system is designed to be able to transfer up to 1 kW power and can operate a LED TV. Before the implementation, the EMF reduction mechanism based on the use of ferrite and a metal shield box was confirmed by an EM simulation and we found that the EMF can be suppressed dramatically by using this shield. The operating frequency of the implemented WPT system is 30.7kHz and the air gap between two coils is 150mm. The power transferred to the load resistor is 147W and the real power transfer efficiency is 66.4 %.

This paper proposes a paradigm for research on broadcast political interviews. Developed using a series of studies, the paradigm introduces core aspects and questions that should be addressed when examining political interviews in a particular society. This paradigm will enable researchers to collect detailed accounts of the interaction between interviewers and interviewees, the structure and tone of the questions posed to interviewees and the interviewees' communicative style when addressing such questions, and the strategies employed by the participants to pursue their goals. It is hoped that the paradigm will encourage the interest and facilitate the study of televised political interviews particularly from the nationally, culturally, and socially diversified Asian countries. Gathering detailed data from non-Western societies in Asia will also facilitate our understanding of the function and effect of political communication from a cross-cultural perspective.

This paper presents a forecasting method for domestic demand of electric home appliances. Because of lack of data, some popular methods such as time series analysis may not be appropriate to forecast such a demand domestically. We suggest a systematic and practical method by considering structural parameters and variables which determine the actual demand. We use this model to forecast the demand of color TV. Since the parameters in our model may be variant according to the change of economic environment, our model leads the user to develop a dynamic model to be used in the well-known System Dynamics Approach.

Three-ring types liquid crystalline compounds having fluoro and isothiocyanate substituent were synthesized and their physical and electro-optical properties were measured to evaluate the applications to active matrix VA liquid crystal displays. The tetrakis(triphenylphosphine)palladium(0) catalyzed cross coupling of aryl boronic acids with aryl halides is used to prepare trans-4'-Alkoxy-2,3-difluoro-3'-isothiocyanato-4-(4-alkylcyclohexyl}-biphenyl series. The synthesized compounds showed the nematic liquid crystalline phase and the negative dielectric anisotropy. The prepared mixtures showed faster response time and lower threshold voltage than their host mixture.

In this paper, a new planar transformer with a novel core configuration that can regulate the leakage inductance is proposed and described in detail. In order to design the slim size power system for flat panel TV, Two planar transformers applied to LLC resonant converter are connected in series at primary and in parallel by the center-tap winding at secondary. In this paper, a 300W low profile LLC resonant converter was built and tested to verify the proposed planar transformer.

To develop new cephalosporin antibiotics with improved antibacterial activities, a series of 7$\beta$-[2-(2-aminothiazol-4-y)-(Z)-2-(1-carboxy-1-methylethoxyimino)acetamido] -3-[5-(heterocycle)thiomethylpy-rrolidin-3-ylthio]methyl-3-cephem-4-carboxylic acid (14~18) having aminothiazol carboxymethylethoxy-imino group on the C-7 position and (heterocycle) thiomethyl pyrrolidinthiomethyl group on the C-3 position of the cephem ring were synthesized. These compounds were tested for antimicrobial activity in vitro against Gram(+) and Gram(-) bacteria. Compounds 15 and 16 showed remarkable antibacterial activity against Salmonella typhimurium TV119 and Alcalienes faecalis KCTC1004, but most of compounds showed lower activity than cefotaxime.

This paper examines the complexities and creative opportunities brought about by the transnational circulation of texts specifically in the areas of transmission, consumption, and adaptation. The circulation of texts and along with it creative elements such as generic forms, tropes, and frameworks for consumption form an integral part in the production and advancement of any form of popular culture. In the process of such circulation, adaptation becomes a form of social and political process necessary for domestic palatability. In this paper, I examine how these complexities can be illustrated in the circulation of one emerging popular form in East and Southeast Asia: Boys Love (BL) television and web series. Using the transnational movement of the BL genre from South Korea, Thailand, and the Philippines, I examine how the circulation and adaptations are inflected by considerations related to regional geopolitics and domestic issues concerned with the creative praxis of representing gender and sexuality.

Animation contents are gradually growing every year, but production period and budget for making one animation contents is insufficient as of now. In particular, in case of animation series that are broadcasted on television, many episodes should be made within a short period of production term. Hence, production pipeline of full three-dimensional animation is frequently chosen in this case. However, another problem emerges as the full three-dimensional animation also requires a lot of time for making high-quality background and for rendering. Composed animation is a production pipeline that attempts to solve such problem. It is a pipeline of producing animation by composing computer graphic (CG) character and real background. It requires relatively small number of human resources compared to the full three-dimensional animation pipeline. Hence, it has an advantage in that natural-looking image can be produced under efficient structure and time for rendering can also be reduced. This paper proposes an efficient process of producing composed animation by using miniature set and three-dimensional computer graphic.
