Cyber-attacks on critical infrastructure have been on the rise. Therefore, cyber-security has become very important for Industrial Control Systems (ICS). For communication protocol in ICS networks, the Open Platform Communications Unified Architecture (OPC UA) communication protocol, which enables secure and platform-independent communications, is expected to be widely used. Beginning from OPC UA v1.04, which was released in 2021, Pub/Sub mode has been supported in addition to Client/Server. Because it can easily support much more communications than usual, it can support all use cases in the industrial sector. An important property of OPC UA is encryption. It is effective in protecting communication data from tampering and eavesdropping but also makes it impossible to monitor communications. In ICS, ill commands to controllers can cause dangerous situations. Even a secure communication protocol cannot guarantee that the data being communicated are safe. There are many types of machines, such as operating support systems and engineering workstations, that can send commands to controllers. They are implemented in common operating systems and may fall victim to a cyber-attack. Therefore, the commands to controllers should be monitored. We propose a monitoring system for encrypted data by OPC UA.
针对关键基础设施的网络攻击呈上升趋势。因此,网络安全对工业控制系统(ICS)来说变得非常重要。在ICS网络通信协议方面,开放平台通信统一架构(OPC UA)通信协议能够实现安全、独立于平台的通信,有望得到广泛应用。从2021年发布的OPC UA v1.04开始,除了客户端/服务器之外,还支持Pub/Sub模式。因为它可以轻松地支持比平常更多的通信,所以它可以支持工业部门中的所有用例。OPC UA的一个重要特性是加密。它可以有效地保护通信数据不被篡改和窃听,但也使通信监控变得不可能。在ICS中,对控制器的错误命令可能导致危险的情况。即使是安全的通信协议也不能保证所通信的数据是安全的。有许多类型的机器,例如操作支持系统和工程工作站,可以向控制器发送命令。它们在普通操作系统中实现,可能成为网络攻击的受害者。因此,应该监控发送到控制器的命令。提出了一种基于OPC UA的加密数据监控系统。

It is challenging to model the relationship between context and intent, and the relationship between context and intent is complicated. The purpose of this study is to make structuralizing context and intention easier in design-related communication such as requirement analysis and architecture design in various fields, and thereby to enable conveying messages as intended. This study also shows cases that context and intention cannot be structuralized. In this study, we assume what a person wants to realize as a “system”, and call the way to realize it as “design”. A person who intends to realize something receives information from someone else who provides supporting information, and implements the design work. This study evaluated language information by clarifying the structure of context and intent of example sentences. Thereby, this study evaluated the effectiveness of structuralization. Finally, this study concludes with future research topics.
语境与意图之间的关系是一个具有挑战性的建模问题,而且语境与意图之间的关系是复杂的。本研究的目的是为了在各个领域的需求分析和架构设计等与设计相关的交流中,更容易地结构化上下文和意图,从而使信息的传递成为可能。本研究还显示了上下文和意图不能结构化的情况。在本研究中,我们假设一个人想要实现的东西是一个“系统”,并将实现它的方式称为“设计”。打算实现某件事的人从提供支持信息的其他人那里接收信息,并实现设计工作。本研究通过厘清例句的语境结构和意图来评估语言信息。因此,本研究评估了结构化的有效性。最后,对未来的研究方向进行了总结。

In the Ogino area of Atsugi City, Kanagawa Prefecture, Wadaiko(Japanese drums) is practiced and passed down to generations for performance at festivals and other events. However, nearby residents would sometimes make noise complaints to the government about the sound generated. Therefore, in Atsugi City, the use of city facilities is prohibited when the main purpose is to practice Wadaiko, creating a situation in which practices are restricted to only some locations. Physical noise control for membranophone instruments such as Wadaiko is difficult from the architectural perspective, as well as the cost perspective if it were to be carried out by the local government. Therefore, the final goal of this study is to find a solution to the noise problem through social measures so that traditional musical instruments whose physical noise control is difficult, such as Wadaiko, will continue to be passed down to generations. First, we uncovered the appearance of the acoustic characteristics of Wadaiko through acoustic measurements. Additionally, by working with the locals, we obtained a clear picture of the current noise complaints and situations. Next, as part of the Noise Compatibility Planning attempt, we set up a website and constructed an operational system to collect feedback from the locals regarding the Wadaiko sounds in order to cater to all lifestyles and circumstances. This paper covers a part of the initial stage of the project. In consideration of people who are easily affected by noise, such as examinees, sick patients, those who are hypersensitive to hearing, and those of specific lifestyles, the community association and the university collaborated to build a website accessible to all residents in the area. Using the website, they schedule practice days and times and create and operate a noise map by monitoring environmental noise regularly. Although not everyone can escape from the Wadaiko noise, we have focused on noise control measures that considered the characteristics of every individual, which is possible only in a small community.
在神奈川县厚木市的Ogino地区,Wadaiko(日本鼓)被练习并代代相传,在节日和其他活动中表演。然而,附近的居民有时会向政府投诉噪音产生的声音。因此,在津木市,当主要目的是练习和太子时,禁止使用城市设施,造成了只在某些地方练习的情况。对于像Wadaiko这样的膜乐器来说,物理噪声控制从建筑的角度来看是困难的,如果由地方政府进行控制,从成本的角度来看也是困难的。因此,本研究的最终目的是通过社会措施找到解决噪音问题的方法,使和台琴等物理噪声控制困难的传统乐器能够继续代代相传。首先,我们通过声学测量揭示了Wadaiko的声学特征。此外,通过与当地人合作,我们清楚地了解了目前的噪音投诉和情况。接下来,作为“噪音兼容性规划”尝试的一部分,我们建立了一个网站,并建立了一个操作系统,以收集当地人对Wadaiko声音的反馈,以满足各种生活方式和环境。本文涵盖了项目初始阶段的一部分。考虑到容易受噪音影响的人群,如考生、病人、对听力过敏的人以及有特定生活方式的人,社区协会和大学合作建立了一个面向该地区所有居民的网站。通过这个网站,他们安排练习的日期和时间,并通过定期监测环境噪音来创建和操作噪音地图。虽然不是每个人都能逃离和田科的噪音,但我们关注的是考虑到每个人的特点的噪音控制措施,这只有在一个小社区才有可能。

In this paper, we consider developing a QGIS plugin to support ideas from multiple keywords. In the existing idea support system, Google searched for any two keywords, created a co-occurrence network diagram, and visualized the relationships between words in a 3D directed graph. However, since there is no geographic information, it is difficult to know where to use the ideas obtained. Since the co-occurrence network diagram is only information on the Web, it is difficult to reflect the latest trend information. Therefore, we have made it possible to examine where the ideas obtained by using QGIS are practical.
在本文中,我们考虑开发一个QGIS插件来支持来自多个关键字的想法。在现有的想法支持系统中,谷歌搜索任意两个关键词,创建一个共现网络图,并将单词之间的关系可视化为三维有向图。然而,由于没有地理信息,很难知道在哪里使用获得的想法。由于共现网络图只是网络上的信息,很难反映最新的趋势信息。因此,我们已经可以检查使用QGIS获得的想法在哪里是实用的。

This paper presents an optimization model using stochastic programming to secure the optimum seat and maximizing the profit of the airline in consideration of overbooking. Airline seat inventory control involves selling the right seats to the right people at the right time. If an airline sells tickets on a first-come, first-serve basis, it is likely to be occupied by leisure travelers and late bookers. Generally, business travelers willing to pay a higher fare will subsequently find no seats left, and revenue from such sales will be lost. While there are various needs that depend on the type of passenger, we propose an optimization model using stochastic programming as a method of maximizing the profit of the airline company by securing seats appropriately and employing the concept of overbooking.
本文利用随机规划方法建立了考虑超售情况下航空公司获得最优座位和利润最大化的优化模型。航空公司的座位库存控制包括在正确的时间把正确的座位卖给正确的人。如果航空公司以先到先得的方式出售机票,很可能会被休闲旅行者和晚订者占据。一般来说,愿意支付更高票价的商务旅行者随后会发现没有剩余的座位,这样的销售收入就会损失。由于乘客的类型不同,乘客的需求也不同,因此我们提出了一个使用随机规划的优化模型,通过适当地确保座位并采用超售的概念,使航空公司的利润最大化。

In recent years, the number of systems using artificial intelligence (AI) is increasing. Even in Chess, Shogi, and Go, which are perfect information games, AI has been used to beat masters. Furthermore, AI has been actively researched in the imperfect information games Poker and Mahjong, and has reached the point where it can be played on par with humans. On the other hand, the werewolf game focused on in our research is an incomplete information game, and it is also necessary to aim for victory as a team using asymmetric information. In this paper, we report that the winning percentage of werewolf team can be improved by taking a team strategy in a 15-player werewolf game.
近年来,使用人工智能(AI)的系统数量不断增加。即使在国际象棋、将军棋和围棋这些完美的信息游戏中,人工智能也被用来击败高手。此外,人工智能在扑克和麻将等不完全信息游戏中也得到了积极的研究,已经达到了可以与人类相提并论的程度。另一方面,我们研究的狼人博弈是一个不完全信息博弈,同样需要利用不对称信息作为一个团队以胜利为目标。本文报道了在15人狼人游戏中,采用团队策略可以提高狼人团队的胜率。

Assessing the consequences of emerging technological concepts on human existence is a challenge that requires unconventional approaches. Science Fiction Prototyping is a methodology that builds on the art of telling stories about our future. Since 2017, we have been using Science Fiction Prototyping to develop an extended approach we call immersive SciFi Prototyping. Immersive SciFi Prototyping features multilinear Virtual Reality (VR) scenarios in order to promote the exchange between scientists and the broad public on the consequences of Emerging Technologies. The resulting discourse will bring together scientists, decision makers and laypeople who can discuss opportunities and risks of Emerging Technologies based on their immersive experiences.
评估新兴技术概念对人类生存的影响是一项挑战,需要采用非常规方法。科幻原型是一种建立在讲述未来故事艺术基础上的方法论。自2017年以来,我们一直在使用科幻原型来开发一种扩展方法,我们称之为沉浸式科幻原型。沉浸式科幻原型以多线性虚拟现实(VR)场景为特色,以促进科学家和广大公众就新兴技术的后果进行交流。由此产生的讨论将把科学家、决策者和非专业人士聚集在一起,他们可以根据自己的沉浸式体验讨论新兴技术的机遇和风险。
