Hotron's vehicle detection sensors allow you to search for products that meet your needs in three categories: "Purpose of Use," "Location of Use," and "Product List." The sensors detect the passage of vehicles, alerting you with rotating lights or switching the display of parking availability. They manage vehicle presence, full parking, and exit warnings in parking lots, contributing to safe driving and smooth operational management within the parking area. They are used in various settings, from coin-operated parking to large-scale parking lots.

Based on practical experience in both support companies and business companies, SBS Marketing Co., Ltd. provides consulting services related to marketing, sales promotion, and customer attraction primarily in the BtoB (business-to-business) sector. On August 14, 2025 (Thursday), they published a page titled "Is the 'Doctrine of Innate Goodness' No Longer Applicable!? The 'Forget the Shame of Your Journey Phenomenon.'" The 'Forget the Shame of Your Journey Phenomenon' refers to the tendency to engage in behavior that violates social norms or causes inconvenience while feeling liberated during travel, something that people typically wouldn't do in their daily lives. This phenomenon can be observed not only among inbound tourists from abroad but also among domestic tourists in Japan. The page explains the representative issues of overtourism, the causes of its occurrence, countermeasures, the already arising negative effects, and the attitudes and behaviors that are required! (Page Overview: Excerpts) ■ Why does "overtourism (tourism pollution)" occur? ■ Countermeasures for the 'Forget the Shame of Your Journey Phenomenon' ■ Negative effects of the 'Forget the Shame of Your Journey Phenomenon' (DL content only) ▼ For more details, please visit this page. https://sbsmarketing.co.jp/blog/forget-the-shame-of-your-journey-phenomenon-2025-08/

In the past, despite a large number of examinees flocking to the university I applied to, the exam was in essay format. What could this mean? Additionally, the book "Guide to Mathematics Exam Techniques" also discusses "The Inside Story of Entrance Exam Grading." Therefore, I asked current university officials about "multiple-choice" and "essay" formats. For more details, please see the link below. https://mbp-japan.com/hyogo/banyohkagaku/column/5200992/

We will clearly explain the basic concepts for understanding the characteristics of each column and strategically selecting the most suitable column for your research and analysis purposes, along with practical selection points. We will also touch on column selection for GC/MS, aiming for a broader acquisition of knowledge. The choice of column is a crucial factor that influences the results of GC analysis. Commercially available columns have various features, such as the type of liquid phase, inner diameter, length, and film thickness. This is an excellent opportunity to deepen your understanding of GC columns, so please take a look.
