Advanced ICT(Information and Communication Technology) and popularization of smart devices change our culture as well as our life style and it has changed the way of learning in education area. There have been some researches to make effective smart education systems based on ICT but few of them were designed by a solid concept of smart education. This is because there have been few researches on developing a conceptual model for smart education. The purpose of this study is to propose a conceptual model for smart education: CTLA(Creation, Teaching, Learning and Assessment) model. It includes activities of smart creation, smart teaching, smart learning, and smart assessment considering ICT environment for education and characteristics of digital natives.

By the change of the times and higher living standards, modern people are becoming interested in life value and culture. On this, in consideration of researches in behavior of people use teacup and drink tea; I develop a concept of interactive teacup which provides music of proper mood for people who drink and enjoy a cup of tea. The concept teacup is produced by adopting the ceramic craft process.

This Paper discusses about the popularity of indie games that have recently caught spotlight from multiple platforms by finding the reason from the games' innovative way of interaction and new attempts in narrative style, and the objective is a preliminary study on indie games' game design, storytelling and it's prestige. This paper focuses on the aspects of indie games compared to established studio games by means of interaction mechanism, directing style and narrative style, and analyzed it with examples. In addition, it looks into examples of Korean indie games entering global platforms such as Steam.

After the Korean Wave with the industrialization of acting arts, scientific actors management has been demanded for the purpose of investment stabilization in related areas. This study was undertaken to develop a new convergence actors evaluation model applying inter-disciplinary research. The assessment factors were selected through literature reviews and the consensus of experts has been derived through Delphi Method. In conclusion, the evaluation criteria for the actors were drawn by 10 different factors. They are composed of qualitative factors such as the ability of acting and communication, degree of understanding of works and production system, actor philosophy and stability of the actors' self-management, physical condition and image, passion and enthusiasm for acting and works, and performance factors such as the stardom, fandom, philmography, audience share and ticket power, and network size and quality.

A thermal micro actualtor has been fabricated using surface micromachining techniques. It consists of doped ploysilicon as a moving part and TEOS(Tetra Ethyl Ortho Silicate) as a sacrificial layer. The polysilicon was annealed for the reduction of residual stress which is the main cause to its deformation such as bending and buckling. And the newly developed HF VPE(vapor phase etching)process was also used as an effective release method for the elimination of sacrificaial layer. With noliquid involved during any of the steps for relasing, unlike other reported relase techniques, the HF VPE pocess has produced polysilicon microstructures with virtually no process-induced stiction problem. The actuation is incured by the thermal expasion due to current flow in active polysilicon cantilever, which motion is amplified bylever mechanism. The thickness of pllysilicon is 2 .mu. m and the length of active and passive polysilicon cantilever are 500 .mu. m, respectively. The moving distance of polysilicon actuator was experimentally conformed as large as 21 .mu. m at the input voltage level of 10 V and 50Hz square wave. These micro actuator technology can be utilized for the fabrication of MEMS (microlectromechanical system) such as microrelay, which requires large displacement or contact force but relatively slow response.

There have been numerous experimental studies for heat transfer measurement technique. This study investigates optical methods for measuring local heat transfer coefficient using thermochromic liquid crystal. Transient and steady methods have been utilized to measure local heat transfer coefficient on a cylinder with a cross flow. The steady method is based on the heat-coating technique and two transient methods adopt by-pass technique and insertion technique, respectively. Both techniques of transient method employ heating technique in which the flow is heated by using the electric heater and cooling technique which cools the preheated cylinder. Experimental results indicate that each methods have nearly similar results. Detailed discussions have been made for its own advantages and disadvantages.

RFID method is a non-contact automatic identification technology, which attaches microchips and antennas to an object in a tag form, to send and process information sent to the network using wireless frequency. Drying and curing process is extremely important which minimizes the resistivity of RFID antennas. This research is about the drying characteristic of conductivity ink, and analyzes and compares the hot-air drying process and infrared drying process. Also, the research was done for the improvement in drying performance by using combined process of hot-air and infrared mechanism. The experiment result shows that the hot-air or infrared drying system used alone cannot meet the required performance in drying printing method using conductivity ink. The combined drying system of hot-air and infrared ray showed resistance low enough in short drying and curing time, and this mechanism makes drying and curing process for mass and continuous production possible on-line.

Recently electronic circuit pattern printing technologies like antennas of RFID process are paid attention. oven drying system is being used since drying and curing time of RFID Tag Gravure printing normally takes from 5 minutes and up to 30 minutes long. In this case the parental material which is of a sheet shape is possible, however, for a massive and a continuous production drying and curing process must be done on-line. This research compared and analyzed the an oven type drying device and a traditional hot-air drying device. Considering the experiment result, the cell depth that shows low resistivity, which doesn't consider the pattern difference, is $31{\sim}33{\mu}m$. Also, oven drying system showed some resistivity after around 120 seconds of drying time, and showed much better performance in minimum resistivity compared to the hot-air drying system.

Separate heat pipe exchanger is considered as the high thermal transportation equipment, because evaporator and condenser are separately positioned in the long distance. Its characteristics are that the working fluid is circulated naturally by the position height of two exchangers. But the operating characteristics are restricted by the temperature of hot and cold fluid, flow pattern and diameter of vapor line, etc. in this study, the vapor pressure and the minimum height of two exchangers are studied about the factors restricting the operating characteristics.
