Abstract
Purpose
The purpose of this paper is to propose that the measurement of salivary amylase activity is an effective index to evaluate the stress of a ship navigator for safe navigation training and education.
Design/methodology/approach
Evaluation comes from the simulator and actual on‐board experiments. The subjects are real captains who have unlimited licenses and cadets who are senior students at Kobe University, navigation course. Stress is evaluated for several situations where a ship navigator makes a lot of decisions, in this case in a narrow passage, entering a port and leaving a port.
Findings
Salivary amylase activity occurs when a ship navigator makes a decision regarding ship handling and collision avoidance. By measuring salivary amylase activity when a student is under duress, cadets' ship‐handling training can be evaluated while onboard a vessel.
Research limitations/implications
Future research will develop cross‐indices with the salivary amylase activity and other physiological indices (nasal temperature and heart rate variability (R‐R interval)), complementary to each other. The salivary amylase activity registers the stress quickly on the spot. Then the nasal temperature and R‐R interval registers the trend and the quick response to the stress (mental workload).
Practical implications
The paper describes an effective index which is useful for evaluating a ship navigator's stress for safe navigation.
Originality/value
Ship navigator's skill and cadet's on‐board training have been evaluated according to performance and a questionnaire as a quantitative evaluation; moreover, stress is evaluated using salivary amylase activity.

Abstract
THE first of the Islington Public Libraries, opened on September 21st, has proved a phenomenal success, and, at the same time, has thrown an interesting light on several modern theories in librarianship. It is, as our readers know, the fust of a system of five libraries, towards the erection of which Dr. Carnegie has given £40,000. The building itself is, as many librarians had an opportunity of judging at the “private view” described in our last number, of an exceedingly well‐lighted and attractive character. The arrangement and accommodation provided present several novel features. On the ground floor, opening from the Central Hall, is the Children's Lending Library and Reading Room. This is stocked with about 3,000 volumes for lending purposes, including French and German juvenile literature, and the reading room portion has seating accommodation for about a hundred children. A representative selection of children's magazines are displayed here, and there are special study‐tables for girls and boys equipped with suitable reference collections. A feature of this room is a striking dado of pictures illustrating scenes from English history, which goes far to make the room interesting and attractive.
