The Faculty of Engineering, Niigata University, Japan, obtained the scholarship in “Short-Stay and Short-Visit scholarshipprograms(SS-SV programs)” for both German and Japanese students in 2011 and 2012. Our short-term student exchange programsproved that a short-term stay in a foreign country worked as an initiator for the students' interest and it strengthen their will tostudy further more in foreign countries.

We report about the international cooperative activities for the engineering education between a German University and a Japanese University. After the experiences for 15 years of cooperation, both in research and student exchange, we learned a lot about the differences between these two educational systems. This report summarizes the differences and the future perspective for the improvement of engineering education based on the understanding of the differences, including advantages and disadvantages, between two educational systems.

Prior research shows that in-store displays have a significant effect on product sales, but no study so far has measured this effect using a qualitative approach that considers the size of the in-store display or its general theme. In this study, a smartphone-based user generated contents (UGC) was used to encourage consumers to post about the in-store displays they liked. This study investigates the relationship between the qualitative content of in-store displays and the sales of the products featured in such displays, and the relationship between posts or likes and the sales of the products featured in the posted liked display. We examine the effects of the contents of in-store display on sales and the mediation effect of the POST or LIKE on these relationship. As the result, this study is the first to explicate the difference of the mediation effect of post on sales by the type of the content of the in-store display. Specifically, the following three aspects were elucidated: (1) “Seasonality” drives user posting on UGC and such posts contribute to increased sales, (2) “Mass” both directly contributes to increased sales and also promotes user postings on UGC, which contribute to increase sales, and (3) “Character” directly influences sales but does not contribute to sales through postings. This study also provides important managerial implications. The results highlight the role of the content of in-store displays in promoting sales. Specifically, if the goal is to simply increase sales, a character themed in-store display will suffice. If the goal is to induce postings to UGC, which will result in increased sales, then a seasonally themed in-store display will work. In this way, expanding consideration to the qualities of in-store displays makes it possible to develop a more strategic understanding of their effects rather than the simple on/off or numerical frequency approach of the past. It must be taken into account that the type of in-store display content that is called for will differ according to whether the objective is to simply increase sales or to also attempt to create WOM promotion.

In 1996, the Faculty of Engineering, Niigata University, Japan entered an era of open student-exchange with Otto-von-GuerickeUniversity Magdeburg, Germany. Thus far, more than 50 of our students have devoted anywhere from three months, to an entire year of their courses, to collaborative efforts with fellow students, (-and some cases, the local citizenry) -in their native environment experiencing unfamiliar education systems and cultures.

Study Design: Retrospective cohort study. Purpose: The aim of our study is to evaluate the extent of posterior spinal dural shift following spinous process splitting multi-level intervertebral lumbar laminectomies, and determine the relationship between posterior spinal dural shift and preoperative parameters. Overview of Literature: There are no existing studies on the posterior spinal dural shift after spinous process-splitting multi-leveled lumbar laminectomies. Methods: We examined 37 patients who underwent spinous process-splitting laminectomies in at least two intervertebral levels, including at the L5/S level. We defined the distance between the vertebral bodies and the anterior edge of the dural sac in the magnetic resonance images at the L5 vertebral level as the anterior dural space (ADS) and detected the difference (d-ADS) between preoperative ADS (pre-ADS) and postoperative ADS (post-ADS). We assessed the relationship between ADS or d-ADS, and preoperative parameters, including age, sex, lumbar lordosis, focal lordosis (FL), and number of decompression levels. Results: Post-ADS was significantly greater than pre-ADS (p<0.001). Pre-ADS was significantly correlated with FL (p=0.44, p<0.01) and also with post-ADS (p=0.43, p<0.01). d-ADS was negatively correlated with pre-ADS (p=−0.37, p<0.05). A single regression analysis revealed that the relationship between d-ADS and pre-ADS was described as d-ADS=3.67−0.46×pre-ADS. In one of three patients whose d-ADS was above the range of two standard errors, reoperation was performed because of impingement of the nerve root caused by the excessive posterior dural shift. Conclusions: Posterior dural shifts occur after spinous process-splitting multi-level lumbar laminectomies, including at the L5/S level. FL and pre-ADS are good predictive factors for posterior dural shift. Excessive posterior dural shift may lead to stretching and impingement of nerve roots and thus require attention.

The effect of carbon dioxide on yeast growth was investigated during the cultivation of pH 5.0 and pH 6.8, by replacing the nitrogen part with carbon dioxide under aerobic conditions. The values of the specific growth rate under pH 5.0 and pH 6.8 conditions became 64.0% and 46.9%, respectively, compared to those before the change in gas composition. This suggests that the effect of carbon dioxide was greater pronounced in pH 6.8 than in pH 5.0. The genome-wide transcriptional response to elevated carbon dioxide was examined using a DNA microarray. As for upregulated genes, it was noteworthy that 3 genes were induced upon entry into a stationary phase and 6 genes were involved in stress response. Of 53 downregulated genes, 22 genes were involved in the ribosomal biogenesis and assembly and 5 genes were involved in the lipid metabolism. These facts suggest that carbon dioxide could bring the cell conditions partially to a stationary phase. The ALD6 gene encoding for cytosolic acetaldehyde dehydrogenase was downregulated, which would lead to a lack of cell components for the growth. The downregulation of ALD6 was greater in pH 6.8 than in pH 5.0, consistent with physiological response. This suggests that it might be the most effective factor for growth inhibition.

Objective: To three-dimensionally elucidate the effects of occlusal hypofunction on the periodontal ligament and alveolar bone proper of rat molars by micro-computed tomography (micro-CT). Methods: Occlusal function in the molar area was restricted by attaching an anterior bite plate on the maxillary incisors and a metal cap on the mandibular incisors of 5-week-old male Wistar rats for 1 week. The periodontal ligament space and alveolar bone proper around roots of the mandibular first molar were assessed by histology and micro-CT. Results: The periodontal ligament space was narrower and the alveolar bone proper was sparser and less continuous in the hypofunction group than in the control group. Further, both the volume of the periodontal ligament and the volumetric ratio of the alveolar bone proper to the total tissue in the region of interest were significantly lower in the hypofunction group (p < 0.05). Conclusions: Occlusal hypofunction induces atrophic changes in the periodontal ligament and alveolar bone proper of rat molars.
