Measuring individual IT capability to efficiently perform business tasks in an enterprise IT environment

This study presents a tool for measuring an individual IT capability to efficiently execute the given tasks on an enterprise IT environment. We developed the measurement items for an individual IT capability based on the previous literature. This research proposed a 13-item scale that can totally measure individual IT capability through a validity and reliability test. The developed tool has four measurement factor and thirteen items. The actual utilization of the tool is confirmed by applying it to a case study.

Bridge Resource Management Training Programs in Korea and Their Effectiveness

Objective: This study aims to introduce the bridge resource management (BRM) training courses implemented in Korea and to analyze their effectiveness in several views. Background: BRM training will be a mandatory course for crew members of ships from 2017. At this stage, it is needed to check if the BRM training courses implemented until now was effective to the Korean maritime safety and to investigate if there are more effective training methods. Method: The effectiveness of BRM training intervention in Korea was compared with that of the other countries, using Kirkpatrick’s (1976) training evaluation framework. Kim (2012)’s data on the BRM training effectiveness were re-analyzed in order to check if the effects of BRM training are dependent on the bridge work experience. Results: Many BRM training courses has been opened in Korea. However, the methods to assess BRM training effects used in Korea focused on the survey of subjective satisfaction level, not investigating trainees’ attitude and behavior change. On the other hand, the effectiveness of BRM training was higher to the bridge officers with long work experience than with shorter work experience. Conclusion: The contents of BRM training should be changed to effectively apply to the context of the real-world exercise and be differentiated depending on the work experience. Research on the methods to measure the BRM training effectiveness is also more required. Application: The results of this study will aid to develop the BRM training courses for bridge officers of ships in the BRM training institutions.

Evaluating end-user computing competency in an organizational computing environment

This study presents an evaluation model that can appraise end-user computing competency in an organizational computing environment. Through factor analysis and reliability analysis on a pilot test of 328 respondents, this study designed a 16-item evaluation model with evaluation system, procedure and method. The validity and application of the model is confirmed by applying it to a case study and presenting its results.

A Pilot Study on the Control Performance of Foot-Controlled Mouse Devices for the Nondisabled People

Objective: In this study, two types of foot-controlled mouse devices are compared with a hand mouse in the input tasks requiring repetitively switching between a keyboard and a mouse. Background: Foot-controlled mouse devices have been developed for persons with impairments in the mobility of their hands. However, some researchers insisted that the foot-controlled mouse devices could be effectively used by the persons with no limits to their hand mobility. There are needs to investigate the efficiency of the foot-controlled mouse devices, when they are used by the nondisabled people. Method: Participants conducted the input tasks, requiring repetitive switches between a keyboard and a computer mouse. The used computer mouse devices were two types of foot-controlled mouse and a typical hand mouse. Participants performed three types of input task for five days and three types of task performance were measured; the number of completed input tasks within a given practice time, subjective satisfaction level and the time wasted for the mouse control. Results: For five days, the performance of input tasks sharply increased in input tasks by foot-controlled mouse devices rather than a hand mouse. After five days, the level of satisfaction on the foot-controlled mouse devices approached to about 76% of a hand mouse satisfaction level. The control time of the foot-controlled mouse devices also approached to about 109% of a hand mouse control time. Conclusion: After only five-day practice, the input task performance by foot-controlled mouse devices approached to that of a hand mouse. This result may suggest that the foot-controlled mouse devices can be effectively used as an alternative input device for the nondisabled people, if input tasks are easy and enough practice time is provided. Application: The results of this study might help to design foot-controlled mouse devices and to expend the usage of them.

Temporal Coupling of Eye Gaze and Cursor on Key Buttons during Text-Entry Tasks

Coupling patterns of eye gaze and cursor movements on key buttons were investigated during a practical text-entry task. A text-entry task can be described as a series of goal-directed aiming tasks. In a typical goal-directed aiming task, eye movements generally lead cursor movements; eye gaze arrives at the target and starts moving to the next target before the cursor. However, in 10% of cases in this experiment, the cursor arrived at the target earlier than the eye gaze did, regardless of text entry speed. Eye gaze started toward the next target key button after the start of the cursors movement in 57% of cases, which also varied with text-entry speed. The coupling patterns, which differed from those observed in typical goal-directed aiming tasks, might be due to the speed requirement of practical text-entry tasks, memory of key button positions, and the use of peripheral vision.

Human Errors and Human Factors in Service Delivery Processes: A Literature Review and Future Works

The aim of this study is to review previous studies on human errors in the service delivery processes. Service industry is sharply growing in the advanced countries. Many people are looking for something to contribute to the service industry. Although there are many research topics related to service domain that human factors and ergonomics specialists can do contribute, a few researchers are studying such topics. This paper indicated how previous researches on human factors and human errors have addressed the service domain, in order to prompt human factor study on the service domain. A variety of sources were inspected for literature reviews, including books and journals of managements, medicine, psychology, consumer behavior as well as human factor and ergonomics. The characteristics of human errors in the service domain were investigated. Human error studies in several service sectors were summarized such as medical service, automotive service operation, travel agent service and call center service. Until now, human factors community was not much interested in human errors in service domain. However, there is much space to contribute to service domain; human error identification, human error analysis and control of human error. The research of human error in service domain can provide clues to improve service quality. This paper helps to guide to identify human error of service domain and to design service systems.

Measuring individual e-Business capability working on an enterprise e-Business system

This study presents a tool for measuring and managing an individual e-Business capability to efficiently execute the given tasks on an enterprise e-Business system. The measurement items for an individual e-Business capability are extracted from the major components of a general competency. By factor analysis and reliability analysis through a pilot test, we proposed a 14-item tool that can totally measure individual e-Business capability. The developed tool has four measurement factor and fourteen items. The utilization of the tool is confirmed by applying it to a case study.
