The purpose of this study is to organize research trends by analyzing healing studies using emotional insects, and to suggest future research directions. As a result, only six emotional insect species were used for healing purposes, and most of the age groups of the test subjects were elementary school students and the elderly. As for the type of research, field application of the healing program was dominant at 76.5%. Effectiveness verification was mainly conducted through questionnaires before and after participating in the healing program. In some cases, stress-related salivary hormones were used as indicators or clinical tests were conducted by medical staff. Based on the results of this analysis, future strategies such as finding new emotional insect species, developing various types of healing program models, and expanding and subdividing the target subjects were suggested to promote the growth of the healing industry using emotional insects in the future.

Repetitive stress injury at the wrist has been reported as a common injury among visual display terminal (VDT) users (i.e., computer users). Adjusting a VDT workstation (computer table and chair) to maintain a correct seated posture while operating a keyboard is perhaps the most frequently recommended preventive solution. This paper proposes an analytical design methodology based on ergonomic design principles for recommending appropriate VDT workstation settings and layout of individual computer accessories on the computer table. The proposed design methodology consists of two interrelated phases: (1) determination of VDT workstation settings, and (2) design of computer accessories layout. Based on the information about the VDT user, dominant task to be performed, typing skill, and degrees of physical and visual interactions between the user and computer accessories, adjustment and layout solutions are recommended to allow having a correct seated posture while minimizing both physical and visual movements. The results from an experiment show that when adjusting the workstation and locating the computer accessories according to the recommendations given by the proposed design methodology, the user's hand movements can be significantly reduced.

Process design is one of the most important fields in metal forming, where the finite element method has appeared a useful method for industrial applications. In this study, a program using the rigid plastic finite element has been developed for preform design in three-dimensional plastic deformation. The surface integration for calculation of the friction between die and workpiece has been implemented with care in numerical treatment. The developed program is applied to a precision coining process for designing an optimal punch.

Recently a technology paradigm of ship has been changed to digital ship, IT shipbuilding convergenced technology development and Human training is very important, that is important role of making high valued shipbuilding industrial development. In this paper, we introduce IT shipbuilding convergenced education program for training human of special skill. A course of study is made of analyzing a survey of IT shipbuilding convergenced core technology in shipbuilding industry. we surveyed marine wireless communication technology, S/W solution for vessel, and CAN & SAN technology in IT filed, and ship-building design and vessel construction technology in shipbuilding field. we put in industry specialist in our education program because we have a gole of training the person are adapted immediately in shipbuilding industry.

This paper deals with design problem of unit load automated storage/retrieval systems (AS/RS). We propose an optimal design model in which the investment and maintenance costs of AS/RS, operating under dual command model is minimized over a time horizon satisfying the warehouse dimensional constraints. The model is formulated as an integer nonlinear program and an algorithm is proposed to find an optimum solution. The valididty of the solution algorithm is illustrated through an example.

Effective use of debugging in computer science education is a topic that has received little attention. Existing tools either are too overwhelming for the novice or are too basic and inflexible. Furthermore, the integration of the debugger into complex IDEs have unfamiliar debuggers from students, resulting in a harmful proliferation of console I/O. In this paper, a new stand-alone educational debugging tool is presented, with simple but powerful tools for easily observing and modifying program execution state. This tool is analyzed from an user perspective, and is compared with existing tools.

Today there is an ever increasing effort to control high-pressure discharge lamps with electronic ballasts. HID lamps can be ignited by high-voltage pulses and need an ignitor to start them. An ignitor gives high-voltage pulses to HID lamps, which have the type of the arc discharge. Two kinds of ignitor circuits have been analyzed by the P-spice program and we have shown experimental results in this paper. The result of this study seems to be able to help to develope various ignitors.

The divided channel is not often used on the river and when the installation is for the controlling of the flow quantity. The determination of the channel size is not a easy task. Model tests are examined to confirm the variation of distribution rate by the method of the channel installation and the position of the structure and the adjustment of numerical simulation is executed by the comparing of the results. This study is to execute numerical model according to installation of divided channel by using AQUADYN program, the 2nd dimension numerical model, and HEC-RAS program, the 1st dimension numerical model, by the shape of divided channel. Also, it compares with difference by method about each case.

This paper discusses two algorithms for recommending notebook computer (NBC) and workstation adjustments so that the user can assume an ergonomic seated posture during NBC operation. Required input data are the user's anthropometric data and physical dimensions of the NBC and the workstation. The first algorithm is based on an assumption that there are no workstation constraints while the second algorithm considers the actual seat height and work surface height. The results from the algorithms include recommendations for adjusting the NBC (tilt angle of the NBC base unit, angle between the base and screen units, and base support height) and the workstation (heights of seat support and footrest, and distance between the body and the NBC).
