근거리 동일 시력에서 연령에 따른 농약 제품 표시 글자의 가독성 평가

This study tried to investigate the difference of the legibility in different age groups (young and old) with same near visual acuity and to provide preliminary guidelines for the text sizes in the pesticides products based on the legibility experiments. To achieve the objective, legibility evaluation experiments were conducted to test the effects of different age(20s, 50-60s), gender, font type(thick gothic-type and fine gothic-type), thickness (plain and bold), and number of syllables(2 and 3 syllables) in the same near visual acuity(0.6). The results showed that legibility 50s was higher than 20s. And 20s are appealed higher discomfort than 50s. Considering these experimental results, it was recommended that the 14 pt or larger characters (100% readable size) should be used the important information such as toxicity, and the minimum character size was 7 pt (50% readable size) for other information.

An Implementation of Document Image Reconstruction System on a Smart Device Using a 1D Histogram Calibration Algorithm

In recent years, the smart devices equipped with imaging functions are widely spreading for consumer application. It is very convenient for people to record information using these devices. For example, people can photo one page of a book in a library or they can capture an interesting piece of news on the bulletin board when walking on the street. But sometimes, one shot full area image cannot give a sufficient resolution for OCR soft or for human visual recognition. Therefore, people would prefer to take several partial character images of a readable size and then stitch them together in an efficient way. In this study, we propose a print document acquisition method using a device with a video camera. A one-dimensional histogram based self-calibration algorithm is developed for calibration. Because the calculation cost is low, it can be installed on a smartphone. The simulation result shows that the calibration and stitching are well performed.

Super-resolution complex amplitude reconstruction of nanostructured binary data using an interference microscope with pattern matching

We propose a new method of optically reconstructing binary data formed by nanostructures with an elemental size several tens of nanometers smaller than the diffraction limit, implemented with an interference microscope and a complex-amplitude image pattern matching method. We examine the size dependency of the data reconstruction capacity using a light propagation simulation based on the finite-difference time-domain (FDTD) method and the Fourier spatial frequency filtering method. We demonstrated that the readable size of the binary nanostructure depends on the magnitude of noise.

Physiology of the Gastrointestinal Tract

Of easily readable size and presenting its material in an attractive format, this work is oriented toward the medical student. It covers the subject under major headings of splanchnic circulation, motor mechanisms, secretion, digestion, and absorption. The bibliography is brief, and controversial points generally are passed over. Although opinions differ over what the medical student should be taught and how material should be presented, coverage certainly offers an adequate background in most areas of gastrointestinal physiology. Hepatic physiology, however, is incompletely examined, and the authors seem not to have decided how to approach this complicated subject. Perhaps hepatic physiology, now so extensive, can be covered adequately only in a separate volume. Some of the material is presented and discussed in a confusing or inadequate manner, especially for a book designed as an introductory text for students. For example, the authors mention results obtained by using a Pavlov pouch, but they
