The Enterprise Resource Planning (ERP) system is the most important information technology system supporting, effectively and efficiently, the operation of an organization. If user training is insufficient, it is difficult for users to utilize the ERP system in full capacity. Therefore, the aim of this study is to propose a method for creating a combination flow to understand the ERP system with both IT system and business perspectives in training contents and manuals at the ERP implementation phase. For the evaluation of this study, we applied the method to an actual ERP implementation project and conducted an interview survey to the person in charge of the project. We suggest that the proposed method is effective after evaluating the results of this study against the four points of ERP training.
企业资源规划(ERP)系统是支持组织有效、高效运作的最重要的信息技术系统。如果用户培训不足,用户很难充分利用ERP系统。因此,本研究的目的是提出一种方法,在ERP实施阶段,从培训内容和手册的IT系统和业务角度创建一个组合流来理解ERP系统。为了评估本研究,我们将该方法应用于一个实际的ERP实施项目,并对项目负责人进行了访谈调查。对比ERP训练的四个方面,我们认为本文提出的方法是有效的。

In bad weather environments such as rainy or snow, car parking becomes difficult. Especially, this makes an impact to some nations since like Japan and Singapore are facing the problem of aging problems. Elder finds it difficult to park their car at night which becomes worse in bad weather. In addition, generally, car parking spaces are narrow which makes the problem more complex. In this paper, we present our preliminary analysis on the performance of different vision sensors, 2D LiDAR, and 3D LiDAR on the basis of the quality point cloud data information and feature detection. Motion planning for auto-car parking depends on the extraction of environmental information. We also present our analysis on the path planning for auto-parking in narrow space on the basis of computational time, path length, and success rate. An approach which utilizes RRT* algorithms is proposed for auto-parking in different parking scenarios with a small model car in the simulation environment.
在雨雪等恶劣天气环境下,停车变得困难。特别是,这对日本和新加坡等面临老龄化问题的国家产生了影响。埃尔德发现很难在晚上停车,这在恶劣的天气下变得更糟。此外,一般来说,停车位很窄,这使得问题更加复杂。在本文中,我们在质量点云数据信息和特征检测的基础上,对不同视觉传感器、2D激光雷达和3D激光雷达的性能进行了初步分析。汽车停车的运动规划依赖于环境信息的提取。在计算时间、路径长度和成功率的基础上,对窄空间自动泊车路径规划进行了分析。提出了一种利用RRT*算法实现小型模型车在不同停车场景下自动泊车的方法。

In recent years, with the progress of economic globalization, corporate and social activities have shifted from vertical integration to horizontal integration. Therefore, the number of collaborative projects in which multiple organizations collaborate is increasing. In such projects, communication between organizations is often a factor in success. Therefore, in this paper, a method for estimating the effect of improving communication between different organizations was examined for collaborative projects with high uncertainty. Since the project is highly unique, the Systems approach focusing on the structure of the project was used as the estimation method. According to the proposed estimation method, the delivery date and cost of the two projects with different uncertainties were compared by changing the degree of communication. As a result, it was confirmed that the effect of improving communication can be grasped quantitatively. These results provide useful suggestions in determining the organizational structure of collaborative projects.
近年来,随着经济全球化进程的推进,企业和社会活动从纵向一体化转向横向一体化。因此,多个组织合作的协作项目的数量正在增加。在这样的项目中,组织之间的沟通通常是成功的一个因素。因此,本文研究了一种评估高不确定性协作项目中改善不同组织之间沟通效果的方法。由于项目是高度独特的,因此使用了关注项目结构的系统方法作为评估方法。根据提出的估算方法,通过改变沟通程度,对具有不同不确定性的两个项目的交付日期和成本进行比较。结果证实,改善沟通的效果是可以定量把握的。这些结果为确定协作项目的组织结构提供了有益的建议。

The number of female deaths caused by breast cancer each year is the second of all causes of death. According to the International Agency for Cancer's Research, early diagnosis can effectively reduce breast cancer mortality. Therefore, our study attempts to construct an automatic X-ray image detection system to help radiologists Interpret the image content to improve the accuracy of diagnosis. In recent years, the development goal of convolutional neural networks is to achieve relatively good accuracy with the least amount of calculation to meet the actual application situation, but ignore the application fields that do not emphasize real-time calculation. Our research will try to use ensemble learning methods to integrate several Efficientnets through two integrated strategies to improve the accuracy of the model. Our study used the DDSM data set, which contains 1329 cases and 5316 digital X-ray images. 641 patients were diagnosed as negative and 688 were diagnosed with benign or malignant tumors. Experimental results show that the accuracy and recall rate of the model can be improved through ensemble learning. The framework proposed in this experiment also achieves an accuracy rate of 87.6 and a recall rate of 91.8%.
每年因乳腺癌导致的女性死亡人数在所有死亡原因中排名第二。根据国际癌症研究机构的研究,早期诊断可以有效降低乳腺癌的死亡率。因此,我们的研究试图构建一个自动x射线图像检测系统,帮助放射科医生解读图像内容,以提高诊断的准确性。近年来,卷积神经网络的发展目标是以最少的计算量达到相对较好的精度来满足实际应用情况,而忽略了不强调实时计算的应用领域。我们的研究将尝试使用集成学习方法,通过两种集成策略整合多个高效网络,以提高模型的准确性。我们的研究使用了DDSM数据集,其中包含1329例病例和5316张数字x射线图像。641例诊断为阴性,688例诊断为良恶性肿瘤。实验结果表明,通过集成学习可以提高模型的准确率和召回率。本实验提出的框架也达到了87.6的准确率和91.8%的召回率。

In this study, we considered projects in which enterprise service systems are developed using artificial intelligence (AI) technologies. Many enterprises have started applying AI technologies to their business functions. When introducing AI technologies effectively, it is important to identify suitable business domains in the enterprise before planning projects. We proposed a GQM+Strategies-based method for identifying business domains where AI technologies can be applied and confirmed the effectiveness of the proposed method through a real business analysis.

Process mining is a technology that extracts useful information from event logs output from information systems and utilizes it for business process analysis. Conventional process mining approaches do not take into account information about organizational goals, and thus may output process models that inhibit the goal of the organization, for example, “to reduce cost”. To solve such problems, goal-oriented process discovery method was proposed as an existing research. On the other hand, one of the methods to generate process models is process model repair. This method uses a process model and an event log as input, and repairs the existing process model to reproduce all the behaviors observed in the event log. However, the existing process model repair methods do not take into account the information about goals. Therefore, in this paper, we propose a goal-oriented process model repair method. It is easy to visually identify and compare which parts of the existing process model satisfy the goal satisfaction and which parts do not satisfy the goal. In addition, the structure of the model is simpler and closer to the initial model, and its effectiveness can be demonstrated. The effectiveness of the model was confirmed by experimental results.
流程挖掘是一种从信息系统的事件日志输出中提取有用信息并将其用于业务流程分析的技术。传统的过程挖掘方法没有考虑到组织目标的信息,因此可能会输出抑制组织目标的过程模型,例如,“降低成本”。为了解决这些问题,面向目标的过程发现方法作为一种现有的研究提出。另一方面,生成流程模型的方法之一是流程模型修复。此方法使用流程模型和事件日志作为输入,并修复现有流程模型以重现事件日志中观察到的所有行为。然而,现有的过程模型修复方法并没有考虑到目标的信息。因此,本文提出了一种面向目标的过程模型修复方法。很容易直观地识别和比较现有流程模型的哪些部分满足目标满足,哪些部分不满足目标。此外,模型的结构更简单,更接近初始模型,可以证明其有效性。实验结果验证了该模型的有效性。

Retailers often make sales forecasts based on the purchase history data they have. When making forecasts, sales may be influenced by periodic factors such as fashion and climate, so the forecast model may consider periodicity. However, most of the proposed models deal with seasonal fluctuations. There is no doubt that seasonal fluctuations are important, but in order to improve prediction accuracy, it is necessary to pay attention to circular fluctuations as well. In this study, we identified the circular fluctuations in sales by Fourier analysis, and constructed a model with higher prediction accuracy than the conventional ARIMA model by taking that factor into consideration.
零售商经常根据他们拥有的购买历史数据做出销售预测。在进行预测时,销售可能会受到诸如时尚和气候等周期性因素的影响,因此预测模型可能会考虑周期性。然而,大多数提出的模式都处理季节波动。毫无疑问,季节波动很重要,但为了提高预测精度,也有必要注意循环波动。在本研究中,我们通过傅里叶分析来识别销售的循环波动,并考虑到这一因素,构建了一个比传统ARIMA模型预测精度更高的模型。

In this study, we perform an empirical analysis of text-mining methodology that extracts sentiment information to predict stock returns. We use the Quarterly Japanese Company Handbook, which is a widely-acclaimed quarterly publication on the Japanese stock exchange, but there are few studies using it. As for the sentiment analysis model, we focus on the Supervised Sentiment Extraction via Screening and Topic Modeling (SSESTM). It has been proposed as a sentiment analysis specialized for stock return forecasting and produced a substantial profit in the U.S. stock market. The SSESTM using the stock return as a teacher label, but we propose using the specific return. The stock return can be decomposed into various common factors such as market and size, and firm-specific return. The Quarterly Japanese Company Handbook provides the comments of companies' earnings forecasts, and it is considered more useful for forecasting specific returns than stock returns including common factors. We examine for prediction the specific return in the Japanese market using Quarterly Japanese Company Handbook. As a result, we confirm that the SSESTM model using four years of articles in the training data gave relatively good results for the high quantile stock groups, but not for the low quantile stocks.
在本研究中,我们对文本挖掘方法进行了实证分析,该方法提取情绪信息来预测股票收益。我们使用的是季刊《日本公司手册》,这是一本在日本证券交易所广受好评的季刊,但很少有研究使用它。在情感分析模型方面,我们重点研究了基于筛选和主题建模的监督情感提取(SSESTM)。它作为预测股票收益的专门情绪分析被提出,并在美国股市上获得了可观的利润。SSESTM使用股票收益作为教师标签,但我们建议使用具体收益。股票收益可以分解为各种常见因素,如市场和规模,以及公司特定收益。《日本公司季刊手册》提供了对公司盈利预测的评论,它被认为对预测具体收益比包括共同因素的股票收益更有用。我们使用《日本公司季刊手册》来检验预测日本市场的具体收益。因此,我们确认使用训练数据中四年文章的SSESTM模型对于高分位数股票组给出了相对较好的结果,但对于低分位数股票组则没有。

As a result, we confirm that the SSESTM model using four years of articles in the training data gave relatively good results for the high quantile stock groups, but not for the low quantile stocks.","PeriodicalId":414070,"journal":{"name":"2021 10th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134051198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the importance of intellectual property is increasing, there have been many infringement cases pertaining to its rights. As per a survey of students ranging from elementary school students to university students, university students, especially those who have the most contact with society and start using electronic devices voluntarily, have the lowest awareness of information ethics. The main reason for this can be that they are not directly harmed. Thus, in this research, we selected nudge tools that are highly effective with university students particularly. These tools were selected from the nudge-type frameworks that work on their subconscious. We devised an approach to improve their awareness of the copyright infringement prevention using these tools, and confirmed the change in awareness with and without the application of the approach via a questionnaire survey. The approach proposed in this research and the obtained findings are intended to induce voluntary actions, not to control the actions through explicit regulations or rules. In particular, it has a high affinity with the management of organizations with diverse objectives and human resources, such as consortiums and NPOs.
在知识产权日益重要的同时,也出现了许多涉及知识产权的侵权案件。根据一项从小学生到大学生的调查显示,大学生,特别是那些与社会接触最多并开始自愿使用电子设备的大学生,信息伦理意识最低。造成这种情况的主要原因可能是他们没有受到直接伤害。因此,在本研究中,我们选择了对大学生特别有效的助推工具。这些工具是从对他们的潜意识起作用的轻推型框架中选择出来的。我们设计了一种方法来提高他们使用这些工具来防止版权侵权的意识,并通过问卷调查来证实在使用该方法和不使用该方法时意识的变化。本研究提出的方法和获得的结果旨在诱导自愿行动,而不是通过明确的法规或规则来控制行动。特别是对财团、非营利组织等具有多种目标和人力资源的组织的管理,具有很高的亲和力。
