This research points out the necessity of customized communication education for engineering students in the era of the Fourth Industrial Revolution. This paper also points out such problems of current communication education as presentation and discussion-focused 'Public Speech' exercises, absence of interests about social issues, and lack of interactive communication learning. In general, as the characteristics of their major education, engineering students are not aggressive in self-questioning and active communication rather than their sensitive reaction to the changes of the new era. Considering these characteristics of engineering students, this research emphasizes that future communication education should be deployed from the major-focused thinking to the development of convergent thinking, from the problem-solving to the problem-finding, and from the contentious thinking to the cooperative thinking. In addition, as a class design reflecting future trends, this research emphasizes, firstly the development of cooperative communication education model, secondly active utilization of SMART technology, and lastly the importance of customized-coaching for each student considering their own characteristics and requirements.

The education system is the communication field should be based on the characteristics of communication science and the function of manpower. However, the current education system at the level of college is insufficient and irrational to meet the requirements of the telecommunication field in our country. The main reasons are as follows: 1. Misunderstanding the characteristics of communication science. 2. Indiscretion of the categories of communication manpower due to lack of coordination between academic circles and communication industrial field. Telecommunication function could be performed only by combining the engineering and the suitable operational control. The communication engineering is similar to the electronic engineering, but the former should follow the miscellaneous international protocol and the domestic regulations, being only a means for the telecommunication function. In order to improve the education system of communiation, we aim to identify the principle of communication science, orthodoxy of the education, the categories of communication industrial field and manpower. The present system has been formed on the basis of ignoring the attributes of manpower and historical background of communication science. Therefore, this paper proposes to set up new departmental organizations for educating communication manpower as the following: In addition, this paper proposes a new curriculum model of the above twodept, and we believe that it well turn out more scientific, effective and reasonable education for the communication science. 1. Modification of the present formation, designated Electronic Communication Department. 2. New formation model: A. The best future model such as establishing ad independent telecommunication college which is composed of : Dept. of Radiocommunication Dept. of Telecommunication Enginnering Dept. of Communication Industrial management Dept. of Transmission Engineering Dept. of Telecommunication Law B. An immediately practicable proposal model instead of the existin Dept.. which is composed of the first two Dept. of the above five Dept. In addition, this paper proposes a new curriculum model of the above two dept. and we believe that it will turn out the education for the communication science to be more scientific, effective and reasonable.

In engineering education, stimulating students' questions and encouraging learning participation are crucial for achieving higher-order thinking abilities. This study aims to investigate the use and effect of an online communication channel in fostering engineering students' questioning abilities. Consequently, in this research, we gauged students' satisfaction with an engineering class that implemented a communication channel, and scrutinized the changes in their perceptions regarding the significance of questions, their engagement in learning, and their academic self-efficacy. In addition, we interviewed the students who participated in the class. The outcomes are as follows: Firstly, student satisfaction improved compared to the previous semester's class where the communication channel was not utilized. Secondly, learners' understanding of the importance of asking questions positively escalated, alongside their actual frequency of posing questions. Thirdly, there was an improvement in learners' active engagement in their studies and their academic self-confidence. The findings of this research suggest that communication channels should be employed to motivate learners to pose questions and involve students in effective learning.

This paper proposes a convergence education method that combines architecture and communication through a documentary film entitled the Talking Architecture. The purpose of this program is to propose a new teaching and learning method for architecture education and investigates what would be an effective method of communication for architects. As mentioned above, this paper proposes a teaching method and a model applicable to actual classes based on the Talking Architect. It is proved that the method can be used for various types of classes and fields such as architectural expression, architectural planning and designing, housing theory, building structure, building materials, and other subject matters. In addition, this paper explores how architects communicate as described in the film. The findings show the potential of integrity, negotiating capability, and the convergent method of thinking and communication between the humanities and architecture as a positive communication model for architects. This paper opens up the possibilities for convergence education in the field of engineering education through three key words: film, architecture, and communication. And this paper is worth in that it is a useful method for developing convergence courses and team-teaching courses.

Professional communication skills in writing and speaking with multiple and complex audiences are required to engineers in society of modern technology. In this paper, we proposed the effective assessment system for the Program Outcomes on the communication skill competence(PO7), which is one of the 12 program outcomes stipulated by ABEEK (Accreditation Board for Engineering Education of Korea). To ensure logical connectivity of the assessment system, we carefully selected the performance criteria by defining the core concept of "written communication" and "verbal communication". Based on the selected performance criteria, the whole process of creating assessment tools and rubrics was explained in detail. It can be expected that the assessment for the Program Outcomes on the communication skill competence would be more systematic by using the proposed assessment system.

This paper investigated the influence of foreign words, otherwise known as loan words, on global communication abilities of university students from two non English-speaking countries: Korea and Japan. To survey the understanding and usage of foreign words which are from English language and used frequently in daily conversation, questionnaires were administered to Korean and Japanese university students majoring in engineering who shared similar linguistic backgrounds. The results were analyzed from global communication viewpoint. Based on the results, methods for improving global communication skills in engineering education were proposed.

The texturing is one of the most important processes for high efficiency crystalline silicon solar cells. The rear side flatness of silicon solar cell is very important for increasing the light reflectance and forming uniform back surface field(BSF) region in manufacturing high efficiency crystalline silicon solar cells. We investigated texturing difference between front and rear side of wafer by texturing of two adhered wafers. As a result, the flatter rear side was obtained by forming less pyramid size compared to the front side and improved reflectance of long wavelength and back surface field(BSF) region were also achieved. Therefore, the texturing of two adhered wafers can be expected to improve the efficiency of silicon solar cells due to increased short circuit current(Isc).

The surface passivation is one of the important methods that can improve the efficiency of solar cells and can be classified into two methods: wet-chemical passivation and film passivation. In this paper, chemical HF treatment were employed for the passivation of n-type silicon wafers and their effects were studied. To investigate film passivation effects, the silicon nitride films were also deposited by PECVD (plasma-enhanced chemical vapor deposition) on n-type silicon wafers treated with chemical HF. The minority carrier lifetime measurements were used for evaluation of the passivation characteristics in the all experiments steps. We confirmed that the minority carrier lifetime was improved with chemical HF treatment due to passivation effects by H-termination.

We have fabricated silver nanowire (AgNW) films as a stretchable and transparent electrode on polydimethylsiloxane (PDMS) substrates using a spray coater. Inherently, they show poor surface roughness and stretchability. To tackle it, we have employed a conductive polymer, poly (3,4-ethylenedioxythiophene) : Poly(styrene sulfonate) (PEDOT : PSS). PEDTO : PSS solution is mixed with AgNWs or spin-coated on the AgNW film. Compared with AgNW film only, PEDOT : PSS film only, and polymer-mixed AgNW films, the AgNW/polymer bilayer films exhibit much better surface roughness and stretchability. It is found that spray-coating of AgNWs on uncured PDMS and spin-coating of PEDOT : PSS solution on the AgNW films enhance the surface roughness of electrodes. Such a bilayer structure also provides a stable resistance under tensile strain due to the fact that each layer acts as a detour route for carriers. With this structure, we have obtained the peak-to-peak roughness ($R_{pv}$) as low as 76.8nm and a moderate increase of sheet resistance (from $10{\Omega}/{\Box}$ under 0% strain to $30{\Omega}/{\Box}$ under 40% strain).
