The purpose of this paper is to clarify the patterns of ethnic identity and acculturation among the 3rd generation of returnee from China in Japan from the viewpoint of segmented assimilation theory. The results of the analysis, the three types of ethnic identity are found; Meritocracy, Hybrid, and Chinese Culture-Oriented. According to segmented assimilation theory, these types are affected by family structure, modes of incorporation, and ethnic community. In this paper it’s found that the modes of incorporation have a strong effect on acculturation and ethnic identity among the 3rd generation of returnee from China, especially the acceptance in Japanese school and its experience, acquisition of culturally tolerant peer group, and keeping a distance from the ethnic community.

It is effective to divide the sequence of events for vocational training instructor candidates and so on to understand history of a law related to the vocational ability. A concept of self-help　co-aid public-assistance is taken up, and it's separated by whether it was the dominant of the three concepts. In the texts and composition of the law, it inclined toward public-assistance until a legal revision in 1985, but co-aid became superior around that time. And the weight of self-help increased by a legal revision in 2007, and it is interpreted a balance of 3 concepts was planned for. It is certain that the amendment in 1985 and 2007 is an epoch legally but it is also necessary to pay attention these changes are somewhat continuous. In addition, consideration is given to the relationship between these categories and the internal labor market and external labor market.

This research clarifies the relevance between qualifying technical education courses and career experiences in colleges, and the development of key vocational abilities and vocational values by students. This study was originally implemented as one part of the surveys within the framework of Prof. Terada’s research project. The analysis was made from longitudinal data (N=83) from students at two Polytechnic Colleges, based on responses in 2013 (freshmen) and 2016 (seniors). Many students had received vocational certificates before entering college, but the tendency had been reinforced since the first year in college. This influences the development of vocational key skills or vocational values. These situations were shown through factor analysis of variables for skills and values, analysis of variances on factor scales, and some career experience variables.

In general, austenitic stainless steel (309 series) with high Cr and Ni contents is used as a filler metal for welding dissimilar mild steel and stainless steel. The reason is to prevent the reduction of Cr and Ni at the weld, and prevent the part from hardening further. However, this filler metal is expensive. In this study, the most common and inexpensive filler metal for mild steel was applied for welding dissimilar mild steel and austenitic stainless steel to a thin plate. We carried out hardness testing, tensile testing, and bend testing on the joint, and compared the results with those of the 309 series filler metal. The welding methods applied were gas metal arc welding, shielded metal arc welding, and gas tungsten arc welding. The results show no problem with practical application even if the filler metal for mild steel was applied.

The safety system is recently developing using microcontroller and sensing, such as the safety mode of the numerical control (NC) for machining center, the light curtain for press machine etc. However, the manual control device/tool cannot be developed, because integrating the sensor or the microcontroller is difficult. In this paper, we suggest the booting system for necessary safety check using AR (Augmented Reality) technology. First, the safety check process is constructed as a reference of PDCA using programing. After that, we confirm the validity of the system for safety check using AR technology, the safety check function of the machine tool and switches is investigated by some workers. The machine tool and many switches are equipped with AR markers, and the workers have the USB camera on head side. Therefore, the switches are measured correctly, and the workers can check the safety using USB camera and AR technology.

In order to quantitatively grasp influence of asymmetry of channel, flow in an eccentric sudden expansion channel in which the channel centers are different on upstream side and downstream side was calculated in Re < 200, where expansion rate was E = 3. The asymmetry of a channel is expressed by an eccentricity B, where a symmetric expansion channel is B = 0 and a channel with one side step is B = 1. Multiple solutions are confirmed in B < 0.35. The critical Reynolds number increases with parabola with respect to eccentricity. Entrance length increases to about 1% according to eccentricity. The reattachment point distance decreases linearly on the short side of a wall of a sudden expansion part and is almost equal except for B = 0 on the long side. The pressure loss coefficient increases due to asymmetry and rapidly as approaching B = 1.

Visible-light communication systems are suitable to realize secure indoor networks. In this paper, a visible-light CDM experimental system developed by the authors with an FPGA and white LEDs is reported. The developed system adopts EWO signaling scheme as an MUI canceller. The signature codes can be selected from MPSCs and inverted MPSCs with a code length of 16. It has five channels on each of which 31.25kHz MIDI data spread with a code sequence is transmitted. The experimental system has five LEDs to transmit coded sequences with a chip rate of 500kcps. Multiplexed optical signal sequence is received by the receiver and decoded by each of five EWO decoders. It has been shown that the average light intensity of the system employing an inverted MPSC with a length of q^2 is, theoretically, q-1 times as high as that of the system employing a non-inverted MPSC with the same length. It is shown that experimental results about light intensity obtained with the developed system agree well with the theoretical results.

In this research, a low-energy secondary emission electron gun using wire ion plasma source was developed. The characteristics of secondary electron beam were investigated in order to achieve main objective, which is to realize the sterilization using pulsed electron beams. The electron dose per unit time was also observed by film-type dosimeter, and it was confirmed to increase at the higher repetition rate. The sterilization experiments were conducted using bacteria called Bacilus pumilus which is the biological indicator of radiation sterilization. It is found that the inactivation effect is intensified by increasing the repetition rate of the electron beam irradiation. Furthermore, morphological damage to the bacteria is observed by Field Emission-Scanning Electron Microscope. It is observed that the damage are caused by radial effects that it is attributed to electron beam irradiation.

The electrostatic precipitator is a device for reducing suspended fine particles, which is widely used from home air cleaner to industrial applications. However, odorous substances cannot be almost reduced with the electrostatic precipitator. Most odorous substances are liquids at room temperature, however these become volatile if vaporized. Generally, gaseous substance is not removed from air with electrostatic precipitator. In this study, we investigated that odorous substances are removed with an electrostatic precipitator, and then, odorous substances are reduced by the ozone generated with corona discharge. The measurement of odorous substances is used odorous sensor corrected for ozone concentration. Furthermore, collected substances at collected electrode in electrostatic precipitator are analyzed by a Fourier transform infrared (FT-IR) with the Nujol methods.
