    The purpose of this paper is to clarify the process of how adventitiously blinded persons take it granted for using white cane through the effect of significant others using interview as a method. Based on the life-story approach, it is found that adventitiously blinded persons have chances of attaining disability acceptance by through of encountering a significant other. Analyzing the effects of significant others, it’s also found that the effects are mainly consist of two functions; person-oriented and group-oriented support. As result, person-oriented support provided by the same blinded community has a strong effect on the use of white cane by through of the choices of assimilation or disassimilation for the community, which makes a divergence on the process of using white cane.

    The purpose of this paper is to clarify what kind of factors affect team errors through the case of manufacturing class in Tokai polytechnic college. Based on recovering theory of team errors, three factors are found; human relationship, technical knowledge, and diffu sion of responsibility. First, human relationship factor affects first step in team making process because they don’t understand mutually. Second, technical knowledge factor affects middle step because they lack of knowledge and certain evidence for pointi ng out of errors. Third, diffusion of responsibility factor affects manufacturing step because they’re inexperienced of manufacturing in fact. Especially, third factor is distinctive feature in students. In educating manufacturing knowledge and skills, the se factors are considered and educators are needed to be conscious for nurturing teamwork.

    Competitors of world skills Japan operate tasks under the high psychosocial pressure. In this study, we explored the relationship between cognitive load appraisal, use of cognitive strategies, and difference of the training length, to find the factors that restrict competitor’s performance in the competition. Questionnaire survey was conducted to competitors who belonged to informational field, and participated in 54th world skills Japan. Statistical analysis shows that high appraisal of cognitive load promotes use of cognitive strategies.it also reveals that more expertise competitor appraise intrinsic cognitive load as high, and tend to use more meta-cognitive strategies than less expertise one. We suggest the conducting skills training for optimize cognitive load during the task operation.

    This article discusses who can acquire social skills through vocational training by analyzing the data from the quantitative survey towards enrollees in vocational training for the graduates from high schools. The analyses examined two hypotheses; namely, (1) the more enthusiastically and autonomously enrollees participate in vocational training, the more they can heighten but also generic skills, and (2) the more enthusiastically and autonomously enrollees spear themselves time for extracurricular work, the more they can heighten generic skills. With x2 test and t test, both hypotheses were supported to some extent. Vocational training has mainly focused on the professional skills, however, this article indicates it helps the enrollees acquire not only professional skills but also generic skills.

    In this work, a newly-designed impact-sliding type vibration power generator using a Fe-Co-V ferromagnetic alloy rod was fabricated and its power generation properties were evaluated. As a result, the open circuit peak-to-peak voltage was 60.4 Vpp and the voltage with 1 kΩ resistor was 32.7 Vpp at maximum. The maximum electric energy obtained with this generator was 253 μJ. It was also found that the induced voltage and the total power increased with increasing number of coil turns. Furthermore, the generator produced in this work was tentatively applied for the power source of a sensor and wireless communication devices and it was found that the generator supplied those devices with electricity, the temperature data were successfully sent to a PC with an USB wireless receiver.

    Corona discharge air ionizers are widely used during the assembly of electronic products to reduce the electrostatic attraction (ESA) and the electrostatic discharge (ESD), that can attach particulate contaminants to printed circuit boards and destroy electronic parts. It is necessary to use the operating conditions of ionizer with caution, because a conventional air ionizer always generates ions. However, operating conditions and theoretical neutralizing of an air ionizer are based on experience for development, because there is not report for the theoretical static neutralization processes. In this study, we investigate static electricity countermeasure for printed circuit board, assessing the relationship between the neutralization current and the neutralization speed. It became clear that it was necessary to examine condition both a mixture of positive and negative static charged model.

    Suppression of the particle generation from the emitter of the corona discharge air ionizer is one of the most important issues to maintain the clean room at low contamination level. The particle generation rate increases with increasing the ion creation rate, because the particles are generated by spattering effect of the generated ions. In order to find out the optimum operating condition by controlling the ion transportation efficiency, that is defined as the ratio of the ion number arrived at the working aria to the of ion number created at the emitter of the air ionizer, we investigated the relationship between the ion transportation efficiency and the frequency of the power supply as an operating condition of the air ionizer. The low frequency operation was suitable to suppress particle generation without reducing the static neutralization performance, because the ion transportation efficiency increased with decreasing the operating frequency.

    The welding of gray cast iron is difficult because it contains a large amount of carbon, which causes the welded part to become brittle. Therefore, several researches have been conducted on welding of gray cast iron. However, none of these studies compared the performance of the joints made using different welding methods and materials. In our study, four kinds of welding methods, namely gas welding, metal-arc welding with covered electrode, semi-automatic arc welding, and TIG welding were applied to the butt joint of a gray cast iron (FC 200). Moreover, eight kinds of specimens were produced by combining the welding materials. Subsequently, the hardness, tensile strength, impact value, workability, and efficiency were quantitatively compared and examined. Based on the results, we arrived at the following conclusions. (1) The gas welding method is not suitable. (2) In metal-arc welding with covered electrode, the tensile strength and impact value of the joint made using the Ni-type welding rod ECNi-CI are high; however, the workability is low. (3) The recommended welding methods are metal-arc welding with covered electrode (E4316), semi-automatic welding (YGW 12), and TIG welding (for repair overlaying).

    Earthquakes sometimes give damages to steel structures. The structures which have not been seriously damaged are still used after an earthquake. The fatigue strength of these structures, however, might have been decreased due to the cyclic loads during an earthquake. In order to clarify the effect of seismic loading on the fatigue strength of the welded joint of a steel structure, varying loading fatigue test of welded joint after large straining was performed. However, few researches have been done on the residual fatigue strength after large strain cycling which enters into gross plasticity. The objective of this study is to clarify the integrity evaluation method of steel structures which experienced seismic loading. The varying loading fatigue test of a welded joint which had been subjected to a large cyclic strain as a simulation of a seismic loading was conducted and the residual fatigue strength was investigated.

    The conventional single-carrier (SC) method using frequency domain equalization (FDE) requires the insertion of the guard interval (GI) to avoid inter-block interference (IBI). Although it achieves a good bit error rate (BER) performance in frequency-selectivity channel, transmission efficiency deteriorates. On the other hand, the overlap FDE, in which the GI insertion is not used, improves the transmission efficiency. The transmission efficiency is not equal between SC-FDE and overlap-FDE. We propose and evaluate methods to equal transmission efficiency by using error correcting codes. Computer simulation shows that the overlap FDE has particularly superior performance in a high E_b⁄N_0 region.

    Manufacturing is closely related to environmental problems. In all processes of commercializing materials, we must be environmentally friendly. In particular, it seems that the load on the environment is great during processing. To that end, it is necessary to cultivate personnel who acquire environmentally friendly skills. The following two points are conceivable as a method of human resources development. Train by incorporating environment-related subjects (department and practical skills: For example, regarding effective utilization of residual materials or waste materials generated during training) into the training curriculum. Train while constantly conscious of 5S's efforts, feelings of treating things, and Mottainai feelings.

    This paper examines the historical transition of quality control (QC) education in public vocational training of Polytechnic University and issues hereafter. Although QC is one of the most important issues in business, vocational training institutes have subordinated QC. From the survey of the relationship between the historical transition of QC education in Polytechnic University and industry, following issues became clear. (1) QC education in Polytechnic University began by Statistical Quality Control (SQC) along with the movement of the age in industry. (2) There was a period that subjects concerning QC were optional, instructors who have less knowledge were nurtured. (3) QC lectures restarted as a compulsory subject in 2012, introductory QC and SQC have been lectured. It is necessary to establish a system for all the instructors to enhance their knowledge of QC. Some programs have been conducted on a trial basis.

    The purpose of this paper is to clarify the process of identity formation among newly appointed vocational training instructors by use of the concept of identity-work, using interview as a method. Analyzing the various aspects of their identity works firstly, it is found that newly appointed vocational training instructors have two kinds of difficulties for job seekers due to their lack of knowledge, skills, and experience at vocational training centers. However, they tend to cope with these problems by adapting "assimilation", "adjustment", and"redefinition" strategy by through of the interaction with colleagues and job seekers. Correspondingly, it is also found that newly appointed vocational instructors form various vocational identities; "skill-oriented", "support-oriented", and"change-oriented". These findings show that the human development of vocational training instructors can be analyzed from the viewpoint of the interaction process focusing on their coping strategy for their difficulties.

    A training curriculum of Kinki polytechnic college application course production electric system technology department is doing a working group learning system. When I observed the group discussion in practice, the brainstorming session did not proceed well. Therefore, in this study, we collected the thought contents before group discussion and analyzed the characteristics and connection of thought elements. As a result, four characteristics were found by analysis.①A group with high work evaluation has a large number of thought elements per person, and is considering a wide range of contents. ②Students are divided in thoughts within the group, and group leaders and members are not communicating. ③A group with high work evaluation has multiple key words and has a complex content. ④The group with higher work evaluation was promoting discussion while linking what the group members are thinking. Based on these results, we developed an educational tool to promote discussion.

    In order to compare or calibrate instruments, a standard is needed. JIS Z 2316-2 as a standard defines 18 characteristics of instruments and measurement methods for the eddy current testing. We made a process document and an automatic measurement system for calibrating eddy current instruments, and tested the effectiveness of this system through experiment. This paper explains the standard and automation of the measurements of the standard. First, the characteristics and measurement methods used in the standard are discussed. Users of this standard need to select proper characteristics in many characteristics for each purpose in accordance to goals. We tried to explain how to select proper characteristics. Second, the results measured by the system are discussed. We measured characteristics of a lock-in amplifier, in comparison with that of other settings of the amplifier using the system. The results rightly show characteristics. It is hoped that the automation will help in measuring characteristics and compare of the eddy current instruments.
