The purpose of this paper is to survey the history of engineering ethics education in Japan for about a decade.
We will find following two features as the history of engineering ethics in Japan: firstly, the engineering ethics
education was introduced in Japan by the government and the industrial world; and there was no interdisciplinary
cooperation for groping for how to teach it effectively, contrary to the United States case. We also propose that we should make the best use of this trial and error for the research ethics education in Japan.

This paper presents a framework for the construction of finite deformation Spectral Stochastic Finite Element Method (SSFEM) which is the expansion of the former research carried out in a range of small deformation theory. In addition, we report on the results of benchmark tests to check the effectiveness of the code made in a framework of ordinary nonlinear FEM as preparations before considering the stochastic phenomena. Furthermore, we carried out the two and three dimensional elasto-plastic bifurcation analysis conducting branch-switching procedures that are required as a fundamental research to construct finite deformation SSFEM.

The purpose of this study was to investigate the new physical fitness test in this year. The subjects were 696 students(Male; 600, Female; 96) of the National Institute of Technology, OYAMA College. Subjects were new physical fitness test of eight kinds (Grip strength, Sit up, Sitting trunk flexion, Side step, 20m Shuttle running, 50m sprint, Standing long jump, Hand-ball throw).
As a result, Male students were significantly lower than the National Average in many events. Also, it was less events that are better than last year. However, a change significant to a female student's result was not accepted at many items. These results suggest implicate that there should be a need to increase the physical activity to improve physical fitness level.

This paper is concerned with the preparative guidance on how to work on the GTEC writing section that I
gave to four classes of second-grade students at my college in 2004. First, I will describe what kind of task
examinees are to work on in this section and state that in the past some students could not write a sufficient number of sentences for their abilities to be appropriately evaluated, even if they had a substantial vocabulary and grammatical competence. Next, I will argue that in order for students to display their abilities in the writing section, some pieces of advice, such as guidelines for creating paragraphs, should be given to them beforehand; at the same time, I will also show how I actually gave such guidance to the students in my classes. Finally, I will compare the essays that those students wrote on the real test with the students that took the same test in the preceding year, and show that the preparative guidance had a beneficial effect on the amount that the students wrote. In addition, I will show that the guidance fortunately made a difference to the growth of students' scores.

The threaded screw hole is often tested using the screw gauge manually. The change of a minute torque acts on the screw gauge when the screw gauge is put in a defective screw and it rotates. In this case, the inspector who inspects the screw judges it as “defective” by the feeling of the change of the minute torque. The purpose of this study is to develop the automatic screw testing system instead of the manually testing. Concretely, this paper
inspects the screw with the gauge, measures the value of the torque, and clarifies the value of the torque which leads to “defective”. Moreover, the screw testing device was developed based on those data.

The model aircrafts using ground effect are adopted as a teaching material for many handicraft classes aimed at young students. That model has no tailplane and flies on the floor surface horizontally, therefore the general flight theory of gliders can’t be applicable. In order to clarify the flight mechanism, observation of flying models by a high-speed camera, wind tunnel experiment and numerical simulation were executed. As a result, the posture angle and external fore on the model could be almost predicted as a function of the flying speed.

This study reports on computational analyses of ghost noise and bit error rate (BER) in memory using computer-generated hologram. The sampling periodicity (
ds) can bring the ghost noise both in the telecentric (T) and lensless (L) optical systems, and the noise is avoided when
ds<λ (:wavelength of light) or when lights by the
ds are diffracted to outside of the image region. The code periodicity (
dc) brings no ghost in the T or L system, but banded brightness unevenness noise is inevitably caused by diffracted images overlapped on hologram in the L system for the codes in this study. However, the BER characteristics in the L system are confirmed to be comparable with those in the T system. The L system makes the memory system simple, so it would be useful for the holographic memory if it is robust also for other disturbances.

Recently, multi-functional small electronic devices such as smart phones and wearable devices have been widely
used. Our research team has proposed the novel communication method for those devices. The communication is using the human body as a transmission path, and electric field and ultrasonic waves transmitted information
hybridly through the human body. We call this method hybrid communication. The system can be utilized high
speed and high security communication by using two kinds of energy. In the previous study on the ultrasonic waves communication, we have succeeded in the linear path communication that distance is less than 5cm. In this time, we have particularly worked on change of the shape of the ultrasonic oscillator in order to expand the communication range. As a result, we have suggested the possibility of the communication between the ring-type wearable device and fingertip.

However, in recent years, screening of fermentative original yeasts from flowers and fruits have been attempted because the needs of unique sake requirements of non-traditional sake tastes are increased. Thus, we tried to screen the fermentative yeasts from Omoigawa cherry that is the City Flower of Oyama-city and to develop of fermented foods such as sake. A selected strain,
Saccharomyces cerevisiae OPJ-1, showed high ethanol productivity almost as much as the Sake yeast kyokai No.7. The sake by
Saccharomyces cerevisiae OPJ-1 brewed at a local brewery this commercial fermentation was released in April 2014.

Flavonoids are major active nutraceutical ingredients in citrus. The flavonoid glucosides were screened for their effect on cell proliferation of vascular endothelial cells. The glucosides of Satsuma mandarin stimulated cell proliferation and production of exogenous beta-glucosidase. The results suggest that the glucosides could have
cell-proliferative activities in vascular endothelial cells, and the molecular mechanism of the proliferation might
involve structural changes in the glucoside binding to its receptor.

Iron oxides such as wuestite, magnetite and hematite were analyzed by a powder X-ray diffraction system
consists of a Cu X-ray source and a one-dimensional semiconductor detector. In this system, a pulse height analyzer(PHA) is also useful to not only cut off continuous X-rays also reduce influence by fluorescent X-rays from the samples containing iron. By adjusting a lower energy level of the PHA, it is possible for the samples to obtain an X-ray diffraction pattern with high peak to background ratio. A semi-quantitative analysis was successfully performed for a two-phase mixture of magnetite and hematite. However the quantitative values of the two-phase mixtures containing wuestite were in no agreement with the respective target values. A correction equation derived from the quantitative results of the two-phase mixtures was of use to determine the quantity of wuestite, magnetite and hematite in the three-phase mixture.

When performing X-ray diffractometry for small amounts of a sample, the background intensity is relatively high with respect to the intensity of the diffraction peaks. Therefore the peak-background (P/B) ratio decreases, and
the analysis will generally be difficult. Because background X-rays are considered mainly due to the reflected X-rays from the sample plate, non-reflective sample plates are useful. Non-reflective sample plates, which are made from silicon, do not easily reflect X-rays. One-dimensional semiconductor detectors are also helpful, which can considerably increase X-ray intensity as a result of integration by a number of semiconductor elements. In this paper, we analyze three various samples of cosmetics using a non-reflective sample plate together with a one-dimensional semiconductor detector. We have diffraction patterns of high P/B ratios, and, as a result, succeed in identifying major parts of inorganic components.

6 latest models of machines have been delivered to the center, and the center has become active for joint researches with local companies. Even if the facility and the machines become latest, in the point of view of relationship between man and machines, there is no guarantee to say that we never cause any mistakes, as long as we are human. To minimize the errors, it is necessary to take measures to verify the errors and estimate the future happening.
