Purpose: Communication skills are considered as one of the essential requirements in medical education, and the training often involves exercising medical interviews with standardized patients(SP) or role play. This study investigated the helpfulness of the communication skills training programs for students' performance on the clinical performance examination (CPX). Methods: Fourth-year students who have taken one of two communication skills programs(exercising communication skills with SP or elective communication skill course with role play) completed a questionnaire on their evaluation of the helpfulness of communication skills programs immediately after finishing the CPX. Then, the programs were objectively assessed by comparing all fourth-year students' CPX scores between program participants and non-participants. Results: About 70% of participants answered that the programs were helpful to perform clinical clerkship and CPX. However, there was no difference in either the total CPX score or 2 categorical scores(integrated clinical encounter, communication and interpersonal skill) between program participants and non-participants. Conclusion: Although the students felt that the communication skills programs were helpful to their clinical activities, this study failed to find objective evidence of any effect of the programs on the CPX results. Communication skills training should be continued during clinical clerkship to maintain or enhance the skills, and it is necessary to introduce more effective methods for precise evaluation of students' communication skills.

Lempel-Ziv coding is one of the most famous source coding schemes. The output of this source coding is usually a non-uniform code, which requires additional source coding, such as arithmetic coding, to reduce a redundancy. However, this additional source code increases complexity and decoding latency. Thus, this paper proposes the optimal maximum a-posteriori (MAP) receiver for non-uniform source non-orthogonal multiple access (NOMA) with symmetric superposition coding (SSC). First, we derive an analytical expression of the bit-error rate (BER) for non-uniform source NOMA with SSC. Then, Monte Carlo simulations demonstrate that the BER of the optimal MAP receiver for the non-uniform source improves slightly, compared to that of the conventional receiver for the uniform source. Moreover, we also show that the BER of an approximate analytical expression is in a good agreement with the BER of Monte Carlo simulation. As a result, the proposed optimal MAP receiver for non-uniform source could be a promising scheme for NOMA with SSC, to reduce complexity and decoding latency due to additional source coding.

Clothing not only offers protection for the body and an aesthetic function but also accomplishes a communication role by delivering a message. And symbolic meanings of clothes deliver important information about the wearer. The T-shirt is one of the most popular items of clothing because of its simplicity and utility, In particular, T-shirt patterns, being simple forms, accomplish non-verbal communication directly by making possible the expression of an idea and showing the personality of the wearer. For these reasons, the T-shirt is becoming established as an Important item of clothing that shows one's personality and individuality in modern society. One purpose of this study is to confirm the communication function of fashion and understand that fashion plays an important symbolic role as a means of communication. Another purpose is to see how T-shirt patterns relate to human communication, through studying of widely accepted T-shirt in modern society. The final purpose is to develop a T-shirt design application based on this study and show how T-skirts contribute to expressing one's individuality and deliver ideas about society through clothing. The results of this study are as follows: 1. T-shirt patterns play a part in non-verbal communication. 2. T-shirt patterns have been variously expressed through conditions of society, culture and types of patterns, and formation techniques. 3. The communication function of T-shirt patterns have been classified to 5 categories; publicity, persuasion, solidarity, art, and fashion. 4 T-shirt design patterns were developed and produced. 5. T-shirt patterns could be useful ways to express individuality of oneself today.

Objectives : The purpose of this study was to help form treatment relationship with patient through more effective communication by defining the relationship between dental hygienist's medical communication and outpatient's reliance satisfaction. Methods : The study researched 273 male and female patients who visited dental clinics and hospitals of Busan from March 12 to March 26, 2012 and its results are as follows. Results : 1. The linguistic communication of dental hygienist was $3.72{\pm}0.63$ and non-linguistic communication was $3.48{\pm}0.58$. 2. For the dental hygienist's reliance satisfaction, the reliance was $3.62{\pm}0.65$ and the satisfaction was $3.74{\pm}0.65$. 3. The dental hygienist's communication degree depending on general characteristic was statistically significant when the job of patient was housewife(p<0.001) and the number of dental clinic visits was more than 10 times (p<0.000). The dental hygienist's non-linguistic communication was statistically significant depending on patient's gender(p<0.000), age(p<0.002), job(p<0.001) and number of dental clinic visits (p<0.000). 4. The dental hygienist's reliance and satisfaction showed statistically significant difference depending on patient's gender(p<0.000), age(p<0.002), job(p<0.001) and number of dental clinic visits (p<0.000). 5. The dental hygienist's non-linguistic communication showed a positive correlation with reliance and satisfaction(p=0.000). Conclusions : When considering the result above, it is necessary to develop the teaching method and material to educate the communication ability of dental manpower. It is necessary to reinforce the curriculum of dental hygienics and the education of dental hygienist to perform effective, smooth communication between dental hygienists.

Fieldbuses are used as the lowest level communication network for real-time communication in factory automation and process control systems. Data generated from field devices can be divided into three categories: sporadic real-time, periodic real-time and non real-time data. Since these data share one fieldbus network medium, it needs a method that allocate the limited bandwidth of fieldbus network to the sporadic real-time, periodic real-time and non real-time traffic. This paper introduces an implementation method of bandwidth allocation scheme introduced in [51 on PROFIBUS. Using the modified PROFIBUS FDL(Fieldbus Data Link layer), the bandwidth allocation scheme introduced in [51 is verified by the experiments.

In this paper, we propose to exploit a multi-code CDMA scheme for power line communication (PLC) systems, and its performance on non-Gaussian impulse and harmonic noises is presented. The proposed multi-code CDMA scheme utilizes convolutional coding and block interleaving to combat with the non-Gaussian noises, and simulation results indicate effective alleviation of these noises, and thus significant bit error rate improvement by the proposed scheme even under strict restriction of frequency band allowed in PLC systems.

Concept development of a real-time Field Programmable Gate Array (FPGA)-based switched Ethernet data communication network for the Man-Machine Interface System (MMIS) is presented in this paper. The proposed design discussed in this research is based on the systems engineering (SE) approach. The design methodology is effectively developed by defining the concept development stage of the life-cycle model consisting of three successive phases, which are developed and discussed: needs analysis; concept exploration; and concept definition. This life-cycle model is used to develop an FPGA-based time-triggered Ethernet (TTE) switched data communication network for the non-safety division of MMIS system to provide real-time data transfer from the safety control systems to the non-safety division of MMIS and between the non-safety systems including control, monitoring, and information display systems. The original IEEE standard 802.3 Ethernet networks were not typically designed or implemented for providing real-time data transmission, however implementing a network that provides both real-time and on-demand data transmission is achievable using the real-time Ethernet technology. To develop the design effectively, context diagrams are implied. Conformance to the stakeholders needs, system requirements, and relevant codes and standards together with utilizing the TTE technology are used to analyze, synthesize, and develop the MMIS non-safety data communication network of the APR1400 nuclear power plant.
