In this study, high school students' perceptions and attitudes toward nanotechnology are examined through questionnaires gathered from 1704 high school students (five general high schools and two science high schools). As a result, the study shows that high school students have generally high perceptions and positive attitudes toward nanotechnology. Science high school students show more positive attitudes and correct knowledge toward nanotechnology rather than general high school students do. High school students get information on nanotechnology via various sources such as TV and internet, whereas they have rarely perceived to get information on nanotechnology in textbooks and science class. They think that newspaper and TV programs are proper methods to introduce new science technology and get information on the advanced science and technology through the internet and science teachers. High school students show positive attitudes toward the application of nanotechnology, whereas they show negative attitudes toward personal information chips and nano-taste enhancer. And they trust nanotechnology researchers and science teachers, whereas they rarely trust about government, public organizations, and internet.

New product development requires information on customers' emotions such as vision, auditory, olfactory, gustatory, or tactile perceptions. In this study, tactile sense which has not been well studied compared to other senses, was measured and statistically analysed for different surface roughnesses of plastic samples. The emotional responses of 37 pairs of positive and negative adjectives describing tactile senses were collected and analysed through the questionnaire to find the correlation between adjectives and surface roughness. Frequency of the first preference for each adjective on four different roughness is obtained, and used for the statistical studies such as factor analysis, multidimensional scaling, or clustering.

The Internet of Things era is approaching where all the things are equipped with smart sensors and communicate through internet. The three core technologies of the Internet of Things are 'detection technology' to get information from things and the environment, 'wired and wireless communications and network infrastructure skills' that support to connect things to the internet, and 'service interface technology' that processes the information appropriate to various services. Smart sensor application can expand to smartphone, smart cars, smart home systems, wearable electronic devices, telemedicine systems, and environmental monitoring systems, etc. In particular, technologies that mimic the five human senses. This study reviews the biological principles of the human senses and the principles of operation, research & development status, technology trends and market analysis of the sensors.

In this study, science teachers' perception and attitude toward nanotechnology are examined through questionnaires gathered from 134 secondary science teachers. As a result, the study shows that science teachers have high perceptiveness. However, they do not understand specific information on nanotechnology correctly. Science teachers have positive attitudes toward nanotechnology and they have perceived risks of nanotechnology as well as benefits of nanotechnology. Science teachers show positive attitudes toward the application of nanotechnology, whereas they show negative attitudes toward personal information chip and nano-taste enhancer. Science teachers are exposed to nanotechnology via various sources such as TV and internet, whereas teachers rarely get information on nanotechnology-related concepts in textbooks and teaching resources. Science teachers have perceived many textbooks do not introduce enough nanotechnology-related concepts. Many teachers try to explain the nanotechnology when textbooks include nanotechnology-related concepts, whereas quite a few of teachers do not introduce the nanotechnology-related concepts in class.

The importance of coatings has been increasing for different purposes such as prevention of static electricity of auto parts or products, improvement of abrasion and corrosion resistance, and enhancement of esthetics. As a method for measuring the thickness of a coating film, a contact method with probe is commonly used. However, it is problematic that accuracy of the sensor is degraded due to sensor output distortion or load phenomenon, which is caused by a change in magnetic permeability of the core. In this study, we propose a method to reduce the measurement error of the coating film by applying the optimized circuit design and the thickness measurement algorithm to the problems caused by the nonlinear characteristics. The tests result which have been taken with different thickness coating samples show that the measurement accuracy is within ${\pm}2%$.

Humans mainly recognize surrounding objects using visual and auditory information among the five senses (sight, hearing, smell, touch, taste). Major research related to the latest object recognition mainly focuses on analysis using image sensor information. In this paper, after emitting various chirp audio signals into the observation space, collecting echoes through a 2-channel receiving sensor, converting them into spectral images, an object recognition experiment in 3D space was conducted using an image learning algorithm based on deep learning. Through this experiment, the experiment was conducted in a situation where there is noise and echo generated in a general indoor environment, not in the ideal condition of an anechoic room, and the object recognition through echo was able to estimate the position of the object with 83% accuracy. In addition, it was possible to obtain visual information through sound through learning of 3D sound by mapping the inference result to the observation space and the 3D sound spatial signal and outputting it as sound. This means that the use of various echo information along with image information is required for object recognition research, and it is thought that this technology can be used for augmented reality through 3D sound.

A variety of methods are used in public advertising to make message persuasive. In order for posters to be more appealing, one good way is to use synesthesia. This study analyzed how synesthesia were used for effective communication. The case analysis is based on the prize winning advertisements chosen by the Korea Broadcast Advertising Corporation. According to the study, synesthesia maximize the efficiency of information delivery. Secondly, in the public campaign posters, sight was the most frequently used sensory element, followed by touch, hearing, smell and taste, respectively. Third, visual tactility was mostly used in nature and environment related posters to effectively deliver the messages. In the topic of social community campaigning, visualization of hearing was applied the most. Lastly, when more than three multisensory stimulations were present in the public campaign, the strongest sense stimulus played the largest part in making message delivery more efficient. The results of this study are expected to provide a scientific basis for future campaign posters that synesthesia expression elements are applied.

Five Plus One' is a result of visual expressions on five senses such as the sense of sight, hearing, smell, taste, and touch. Although I searched for the data on five senses, there were only information which was quoted in various languages and scientific bases, and also most of the books written were far from artistic expressions including visual pleasure and emotional expressions. In addition, most materials were mainly textbooks for children's intellectual development, academic papers, and medical publications. Therefore, I made this book that makes us to communicate about five senses and an inspiration even though we have a problem to read writings in both Korean and English. I arranged visual elements using illustrations and typography in various ways based on the scientific evidence.
